Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial months, on the basis of actual days elapsed over a 30-day month. 

(b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Regular
Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the office or agency of the Company maintained by the Company for such purposes in

holding Physical Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to such Holders or, upon application by such a Holder to the Note Registrar not later than the relevant Regular Record Date, by wire transfer
in immediately available funds to that Holder’s account within the United States, if such Holder has provided the Company, the Trustee or the Paying Agent (if other than the Trustee) with the requisite information necessary to make such wire
transfer, which application shall remain in effect until the Holder notifies, in writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its
nominee. 
 (c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue
interest per annum at the rate borne by the Notes, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the
Company, at its election in each case, as provided in clause (i) or (ii) below: 
 (i) The Company may elect to make
payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the
following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of
such notice, unless the Trustee shall consent in writing to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall
make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause
provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the
receipt by the Trustee of

Days before such notice is to be sent and in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be delivered to each Holder at its address as it
appears in the Note Register, or by electronic means to the Depositary in the case of Global Notes not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor
having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable
pursuant to the following clause (ii) of this Section 2.03(c). 
 (ii) The Company may make payment of any
Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such
exchange or automated quotation system, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

of Note attached as Exhibit A hereto, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 16.10), shall be entitled to the benefits of this Indenture or be
valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered
hereunder and that the Holder is entitled to the benefits of this Indenture. 
 In case any Officer of the Company who shall have signed any
of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the
Person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on behalf of the Company by such Persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although

shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed
the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with

to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the

 No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or any Paying Agent for any exchange or registration of transfer of Notes, but the Company or the Trustee may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar
issue or transfer tax or other similar governmental charge required by law or permitted pursuant to Section 13.02(d) or Section 13.02(e).

exchange or register a transfer of (i) any Notes selected for redemption in accordance with Article XV, except the unredeemed portion of any Note being redeemed in part, (ii) any Notes surrendered for conversion or, if a portion of any
Note is surrendered for conversion, such portion thereof surrendered for conversion or (iii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article XIV. 

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. 

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fourth
paragraph from the end of 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 a nominee of the Depositary. The transfer and
exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on
transfer set forth herein) and the procedures of the Depositary therefor.

subject to the restrictions on transfer set forth in this Section 2.05(c) (including those contained in the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company
with notice to the Trustee as provided below. 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) and
Section 2.05(d), 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, or such shorter period of time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, any
certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.05(d), if applicable)
shall bear a legend in substantially the following form (unless such Notes 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, or sold 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 notice thereof to the Trustee):

THE SECURITIES ACT, OR 
 (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR
ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN
ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER FOR THE COMPANY TO DETERMINE THAT THE PROPOSED
TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

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. 
 Any 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 required by this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the Custodian in writing to so
surrender any Global Note as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note
so exchanged therefor shall not bear the restrictive legend specified in this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee and the Holders after a registration statement, if
any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act. 

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 (i) 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 and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a
beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.05(c). 

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints DTC to act as Depositary with
respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling
or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not
appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the Company shall
execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner
in a principal amount equal to the principal amount of such Note corresponding such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes
(or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled. 

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(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. Upon execution and authentication, the Trustee shall deliver such Physical Notes to
the Persons in whose names such Physical Notes are so registered. 
 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 existing instructions 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 standing procedures and existing instructions between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement
shall be made on the Schedule of Exchanges of such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 

Neither the Company, the Trustee, the Paying Agent 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. Subject to its compliance with
its respective obligations under this Indenture, the Company, the Trustee, the Paying Agent and the Conversion Agent shall have no responsibility or liability for any act or omission of the Depositary. 

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. 
 (d) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon
conversion of such Note shall bear a legend in substantially the following form (unless the Note or such Common Stock has 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, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon conversion of
Notes that 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, or 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 with written notice thereof to the Trustee and any transfer agent for the Common Stock):

 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 

(1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE
MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 

(2) AGREES FOR THE BENEFIT OF INFINERA CORPORATION (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR
OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE OF THE SERIES OF NOTES UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED OR SUCH
SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: 

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D)
ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER FOR THE COMPANY TO DETERMINE THAT
THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the
certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common
Stock, which shall not bear the restrictive legend required by this Section 2.05(d).

 (e) Any Note or Common Stock issued upon the conversion or exchange of a Note that is
repurchased or owned by any of the Company’s “affiliates” (as defined in Rule 144) may not be resold by such affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of
the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted security” under Rule 144 that have been reacquired by any of them. The Company will cause any Note that is
repurchased or owned by the Company to be surrendered to the Trustee for cancellation as described in Section 2.08. 

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 its written request, the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver a new Note, bearing a registration 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 such 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 such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

The Trustee or such authenticating agent 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, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar or any co-Note Registrar for
any exchange or registration of transfer of any substitute Note, but, 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 documentary, stamp or similar issue or
transfer tax required in connection therewith. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article XIII shall become mutilated or be
destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated
Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them
harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion
Agent 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 or payment or conversion or repurchase or redemption 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 or payment or repurchase or redemption or conversion of negotiable instruments or other securities without
their surrender. 

  
 19 












 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 4.02 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. 
 Section 2.08 Cancellation of Notes Paid, Converted, Etc. The Company shall cause all
Notes surrendered for the purpose of payment, repurchase, redemption, registration of transfer or exchange or conversion, if surrendered to the Company or the Company’s agents, Subsidiaries or Affiliates, to be surrendered to the Trustee for
cancellation. All Notes delivered to the Trustee shall be canceled promptly by it, and except for any Notes surrendered for registration of transfer or exchange, no Notes shall be authenticated in exchange 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 disposition, shall deliver a certificate of such disposition to the Company. If the Company shall
acquire any of the Notes, such acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 

Section 2.09 CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in
use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness 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, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company
shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 Section 2.10 Additional
Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other
than differences in the issuance date, issue price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes
initially issued hereunder for U.S. federal income tax or securities law purposes, such additional Notes shall have 

  
 20 












 
one or more separate CUSIP numbers. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of
Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters required by Section 16.05, and such Opinion of Counsel to include a customary legal opinion as to the enforceability under New York law of such additional
Notes, which opinion may contain customary exceptions and qualifications. In addition, the Company may, to the extent permitted by law, and without the consent of the Holders, directly or indirectly (regardless of whether such Notes are surrendered
to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or
other derivatives. The Company may, at its option and to the extent permitted by applicable law, reissue, resell or surrender to the Trustee for cancellation any Notes that the Company may repurchase, in the case of a reissuance or resale, so long
as such Notes do not constitute restricted securities upon such reissuance or resale. Any Notes that the Company repurchases shall be considered outstanding (except for voting purposes) unless and until such time the Company surrenders them to the
Trustee for cancellation and, upon receipt of written order from the Company, the Trustee shall cancel all Notes so surrendered in accordance with Section 2.08. 

ARTICLE III 

SATISFACTION AND DISCHARGE 

Section 3.01 Satisfaction and Discharge. This Indenture and the Notes shall, upon request of the Company contained in an
Officer’s Certificate cease to be of further effect, and the Trustee, at the expense and request of the Company, shall execute such instruments reasonably requested by the Company acknowledging satisfaction and discharge of this Indenture, when
(a) (i) all Notes theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money has
theretofore been irrevocably deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d)) have been delivered to the Trustee for
cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether at the Maturity Date, any Redemption Date, any Fundamental Change Repurchase Date,
upon conversion or otherwise, cash or, solely in the case of conversion, cash and, if applicable, any shares of Common Stock sufficient to pay all of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and
(b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this 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. 

ARTICLE IV 

PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01 Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the
principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and in the
Notes. 

  
 21 












 Section 4.02 Maintenance of Office or Agency. The Company will maintain
an office or agency in New York, New York, or any other office or agency in the United States of America so designated by the Trustee, where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or
repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency in the United States of America so designated by the Trustee as a place where Notes may be presented for payment or for
registration of transfer. 
 The Company may also from time to time designate as co-Note Registrars
one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office in New York, New York, or any other office or agency in the United States of America so designated by the Trustee as a place for such purposes. The Company will give prompt written notice
to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices
or agencies, as applicable. 
 The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and
Conversion Agent and the Corporate Trust Office as one such office or agency of the Company for each of the aforesaid purposes; provided that the Corporate Trust Office shall not be a place for service of legal process on the Company. 

Section 4.03 Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to
avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder. 

Section 4.04 Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee,
the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 

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

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

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

  
 22 












 The Company shall, on or before each due date of the principal (including the Redemption
Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Redemption Price and the Fundamental Change
Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing of any failure to take such action; provided that if such deposit is made
on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date. 
 (b) If the Company
shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside,
segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest so becoming
due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable)
of, or accrued and unpaid interest on, the Notes when the same shall become due and payable. 
 (c) Anything in this Section 4.04 to
the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by
the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the
Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts. Upon the occurrence of any event specified in Section 6.01(h) or Section 6.01(i), the Trustee shall automatically
become the Paying Agent. 
 (d) Subject to applicable escheatment laws, any money and shares of Common Stock deposited with the Trustee or
any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on and the consideration due upon
conversion of, any Note and remaining unclaimed for two years after such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) or interest has become due and payable shall be paid to the Company on
request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease. 

Section 4.05 Existence. Subject to Article XI, the Company shall do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence. 
 Section 4.06 Rule 144A Information Requirement and Annual
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, promptly provide to the Trustee and shall, upon written request, provide to the Trustee, any Holder, beneficial owner or prospective
purchaser of such Notes or any shares of Common Stock issuable upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to 

  
 23 












 
facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial owner of such Notes or such Common
Stock may reasonably request to the extent required from time to time to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A under the Securities Act, as such rule may be amended from time
to time. 
 (b) The Company shall file with the Trustee within 15 days after the same are required to be filed with the Commission (giving
effect to any grace period provided by Rule 12b-25 or any successor rule under the Exchange Act or any similar or successor grace period), copies of any documents or reports that the Company is required to
file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (excluding any such information, documents or reports, or portions thereof, subject to confidential treatment and any correspondence with the Commission). Any such
document or report that the Company files with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be filed with the Trustee for purposes of this Section 4.06(b) at the time such documents are
filed via the EDGAR system (or any successor thereto), it being understood that the Trustee shall not be responsible for determining whether such filings have been made. 

(c) Delivery of the reports and documents described in subsection (b) above to the Trustee is for informational purposes only, and the
Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which
the Trustee is entitled to conclusively rely on an Officer’s Certificate). 
 (d) If, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes offered pursuant to the Offering Memorandum, the Company fails to timely file any
document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), or such Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months preceding (as a result
of restrictions pursuant to U.S. securities laws or the terms of this Indenture or such Notes), the Company shall pay Additional Interest on such Notes. Such Additional Interest shall accrue on such Notes at the rate of 0.50% per annum of the
principal amount of such Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is continuing or such Notes are not otherwise freely tradable by Holders other than the Company’s
Affiliates (or Holders that have been the Company’s Affiliates at any time during the three months preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or such Notes. As used in this
Section 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the
Commission pursuant to Section 13 or 15(d) of the Exchange Act. 
 (e) If, and for so long as, the restrictive legend on the Notes
offered pursuant to the Offering Memorandum specified in Section 2.05(c) has not been removed (or deemed removed pursuant to this Indenture), such Notes are assigned a restricted CUSIP number or such Notes are not otherwise freely tradable by
Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or such Notes) as
of the 380th day after the last date of original issuance of such Notes, the Company shall pay Additional Interest on such Notes at a rate equal to 0.50% per annum of the principal amount of such 

  
 24 












 
Notes outstanding until the restrictive legend on such Notes has been removed in accordance with Section 2.05(c) (or deemed removed pursuant to this Indenture), such Notes are assigned an
unrestricted CUSIP number and such Notes are freely tradable by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months preceding) (without restrictions pursuant to
U.S. securities laws or the terms of this Indenture or such Notes). 
 (f) Additional Interest will be payable in arrears on each Interest
Payment Date following accrual in the same manner as regular interest on the Notes. 
 (g) The Additional Interest that is payable in
accordance with Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03. 

(h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or Section 4.06(e), the Company shall deliver to
the Trustee an Officer’s 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 (and, if applicable, the Notes with respect to 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 Officer’s Certificate setting forth the particulars of such payment. 

Section 4.07 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall
not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or
interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly
waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted. 
 Section 4.08 Compliance Certificate; Statements as to Defaults. The
Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2022) an Officer’s Certificate stating whether or not the signers thereof have
knowledge of any failure by the Company to comply with all conditions and covenants then required to be performed under this Indenture and, if so, specifying each such failure and the nature thereof. 

In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within 30 days after the Company becomes aware of
the occurrence of any Event of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or proposing to take in respect thereof;
provided that the Company shall not be required to deliver such notice if such Event of Default or Default has been cured or waived before the date on which the Company is required to deliver such notice.

 26 












 
equivalent) in the aggregate of the Company and/or any such Significant Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness
becoming or being declared due and payable prior to its stated maturity or (ii) constituting a failure to pay the principal of any such indebtedness when due and payable at its stated maturity, upon required repurchase, upon declaration of

Section 6.02 Acceleration; Rescission and Annulment. In case one or more Events of Default shall have occurred and be continuing
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the Company), unless the principal of all of the Notes shall have already become due
and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by notice in writing to the Company (and to the Trustee if given by Holders),
may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained
in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the Company occurs and is continuing, 100% of the principal of, and accrued and
unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable. 
 The immediately preceding
paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or
entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise
than by acceleration (with 

  
 27 












 
interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the
Notes) and amounts due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this
Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such
case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default
with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no
such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and
annulment shall extend to or shall affect any continuing Default or Event of Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid interest on, any Notes or (ii) a failure to pay or deliver, as the case may
be, the consideration due upon conversion of the Notes. 
 Section 6.03 Additional Interest in Lieu of Reporting Default.
Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in
Section 4.06(b) shall, for the first 360 days after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to (1) 0.25% per annum of the principal amount of the
Notes outstanding for each day during the 180 day period after the occurrence of such Event of Default and (2) 0.50% per annum of the principal amount of the Notes outstanding beginning on and including the 181st day following the occurrence of such
an Event of Default during which such Event of Default is continuing. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or
Section 4.06(e). If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. On the 361st day after such Event of Default (if the Event of Default relating to
the Company’s failure to comply with its obligations as set forth in Section 4.06(b) is not cured or waived prior to such 361st day), the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does
not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company elected to make such payment of Additional Interest in accordance with this Section 6.03 but does not pay the Additional
Interest when due, the Notes shall be subject to acceleration as provided in Section 6.02. 
 In order to elect to pay Additional
Interest as the sole remedy during the first 360 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify in writing all Holders of the Notes, the Trustee and the Paying Agent of
such election in writing prior to the beginning of such 360-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

 In no event shall Additional Interest payable at the Company’s election for failure to comply with its obligations as set forth in
Section 4.06(b), together with any Additional Interest that may accrue pursuant to Section 4.06(d) as a result of the Company’s failure to timely file any document or report that the Company is required to file with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), accrue at a rate in excess of 0.50%
per annum pursuant to this Indenture, regardless of the number of the events or circumstances giving rise to the requirement to pay such Additional Interest. 

  
 28 












 Section 6.04 Payments of Notes on Default; Suit Therefor. If an Event of
Default described in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes
for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the
Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the
property of the Company or any other obligor upon the Notes, wherever situated. 
 In the event there shall be pending proceedings for the
bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or
such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims
for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem
necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same
after the deduction of any amounts due to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such
payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and
disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses,
advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other
property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

  
 29 












 All rights of action and of asserting claims under this Indenture, or under any of the
Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the
Holders of the Notes. 
 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of
this Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or
abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the
Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall
continue as though no such proceeding had been instituted. 
 Section 6.05 Application of Monies Collected by Trustee.
Any monies or property collected by the Trustee pursuant to this Article VI with respect to the Notes shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies or property, upon
presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 

First, to the payment of all amounts due the Trustee (in each of its capacities hereunder) under Section 7.06; 

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash
due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such
overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto; 
 Third, in
case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of the Redemption Price, the Fundamental Change Repurchase Price
and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of
interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Redemption
Price, the Fundamental Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of
interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Redemption Price, the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and


  
 30 












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

Section 6.06 Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable,
the Redemption Price and the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of
any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for
any other remedy hereunder, unless: 
 (a) such Holder previously shall have given to the Trustee written notice of an Event of Default and
of the continuance thereof, as herein provided; 
 (b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding
shall have made written request upon the Trustee to pursue such remedy hereunder; 
 (c) such Holders shall have offered to the Trustee such
security or indemnity satisfactory to it against any loss, liability or expense to be incurred therein or thereby; 
 (d) the Trustee for 60
days after its receipt of the request and offer of security or indemnity, had not complied with such request; and 
 (e) no direction that,
in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such
60-day period pursuant to Section 6.09, 
 it being understood and intended, and being expressly covenanted by
the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common
benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

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

  
 31 












 Section 6.07 Proceedings by Trustee. In case of an Event of Default the
Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law
or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable
right vested in the Trustee by this Indenture or by law. 
 Section 6.08 Remedies Cumulative and Continuing. Except as
provided in the last paragraph of Section 2.06, all powers and remedies given by this Article VI to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other
powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the
Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any
acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article VI or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Holders. 
 Section 6.09 Direction of Proceedings and Waiver of Defaults by Majority of Holders.
The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that such direction shall not be in conflict with any rule of law or with this Indenture, and the Trustee may
take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the
Trustee in personal liability (it being understood that the Trustee shall not have an affirmative duty to ascertain whether or not any such direction is unduly prejudicial to any other Holder). The Holders of a majority in aggregate principal amount
of the Notes at the time outstanding determined in accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment
of accrued and unpaid interest, if any, on, or the principal (including any Redemption Price and any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure
by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article X cannot be modified or amended without the consent of
each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder, but no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the
Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

  
 32 












 Section 6.10 Notice of Defaults. The Trustee shall, within 90 days after
it receives written notice of the occurrence and continuance of a Default with respect to the Notes of which it has actual knowledge, send to all Holders as the names and addresses of such Holders appear upon the Note Register, notice of all such
Defaults, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Redemption Price and Fundamental Change
Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as it in
good faith determines that the withholding of such notice is in the interests of the Holders. 
 Section 6.11 Undertaking to Pay
Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the
provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the
Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not
limited to, the Fundamental Change Repurchase Price with respect to the Notes being repurchased as provided in this Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert
any Note in accordance with the provisions of Article XIII. 
 ARTICLE VII 

CONCERNING THE TRUSTEE

affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders
have offered (and, if requested, provided) to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense that might be incurred by it in compliance with such request or direction. 

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly
negligent failure to act or its own willful misconduct, except that: 
 (a) prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default that may have occurred:

Indenture against the Trustee; and 
 (ii) in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such
certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture
(but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

authorized or within the rights or powers conferred upon it by this Indenture;

action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined as provided in Section 8.04

protection to, the Trustee shall be subject to the provisions of this Section;

Registrar with respect to the Notes; 
 (g) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this
Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless a Responsible Officer of the Trustee had actual knowledge of such
event; 
 (h) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses, fees, taxes or other costs incurred with respect thereto or for losses
incurred as a result of the liquidation of any such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely
written investment direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the Company; 

  
 34 












 (i) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent,
Conversion Agent, Bid Solicitation Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article VII shall also be afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid
Solicitation Agent or transfer agent; and 
 (j) under no circumstances shall the Trustee be liable in its individual capacity for the
obligations evidenced by the Notes.

own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers.

(b) before the Trustee acts or refrains from acting, it shall be entitled to receive upon request an Officer’s Certificate or an Opinion

(d) the Trustee may consult with counsel of its selection and require an Opinion of Counsel and any advice of such counsel or Opinion of
Counsel shall be full and complete authorization and protection or reliance on in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit,

liability of any kind by reason of such inquiry or investigation;

respect of the performance of its powers and duties hereunder;

custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney appointed by it with due care hereunder; 

(j) the permissive rights of the Trustee enumerated herein shall not be construed as duties; and 

(k) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with
such request or direction. 
 In no event shall the Trustee be responsible or liable for any special, indirect, punitive or consequential
loss or damage of any kind whatsoever (including, but not limited to, lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. The Trustee shall not be charged with knowledge
of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default is received by
the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. 
 Section 7.03
No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for
the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any
Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture or any money paid to the Company or upon the Company’s direction under any provision of this Indenture. 

Section 7.04 Trustee, Paying Agents, Conversion Agents, Bid Solicitation Agent or Note Registrar May Own Notes. The
Trustee, any Paying Agent, any Conversion Agent, Bid Solicitation Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying Agent,

 Section 7.06 Compensation and Expenses of Trustee. The Company covenants
and agrees to pay to the Trustee, in any capacity under this Indenture, from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the reasonable compensation and the expenses and disbursements of its agents and
counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its gross negligence or willful misconduct as determined by a final, nonappealable decision of a court of competent
jurisdiction. The Company also covenants to indemnify the Trustee or any predecessor Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and their officers, directors, employees and
agents and any authenticating agent for, and to hold them harmless against, any loss, claim (whether asserted by the Company, any Holder or any other Person), damage, liability or expense incurred without gross negligence or willful misconduct as
determined by a final, nonappealable decision of a court of competent jurisdiction on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in
connection with the acceptance or administration of this Indenture or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this
Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior lien to which the Notes are hereby made subordinate on all money or property held or
collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this
Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The obligation of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation
or removal of the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents
and employees of the Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and
its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 6.01(h) or Section 6.01(i) occurs, the expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. 

Section 7.07 Officer’s Certificate as Evidence. Except as otherwise provided in Section 7.01, whenever in
the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of gross negligence and willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the Trustee, and such
Officer’s Certificate, in the absence of gross negligence or willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith
thereof. 

  
 37 












 Section 7.08 Eligibility of Trustee. There shall at all times be a
Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant
to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 

Section 7.09 Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of
such resignation to the Company and by delivering notice thereof to the Holders. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of
Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such
notice of resignation to the Holders, the resigning Trustee may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes
for at least six months may, subject to the provisions of Section 6.11, on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 
 (b) In case at any time any of the following shall
occur: 
 (i) 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 
 (ii) the Trustee shall become incapable
of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, 
 then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a successor
trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of
Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself or herself and all others similarly situated, at the expense of the Company, 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. If no successor
trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of removal to the Holders, the Trustee being removed may, at the expense of the Company, petition any court of competent jurisdiction
for the appointment of a successor trustee with respect to the Notes. 
 (c) The Holders of a majority in aggregate principal amount of the
Notes at the time outstanding, as determined in accordance with Section 8.04, may at any time remove the Trustee and nominate a successor trustee by so notifying the Trustee and the Company in writing not less than 30 days prior to the
effective date of such removal. If within ten days after notice to the Company of such nomination the Company objects thereto, the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09 provided, may
petition any court of competent jurisdiction for an appointment of a successor trustee. 

  
 38 












 (d) Any resignation or removal of the Trustee and appointment of a successor trustee
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 by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall
execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request
of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior lien to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit
of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06. 
 No successor trustee
shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08. 

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at
the written direction and at the expense of the Company shall mail or cause to be delivered notice of the succession of such trustee hereunder to the Holders. If the Company fails to mail such notice within ten days after acceptance of appointment
by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
 Section 7.11
Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to
which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee
hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust
business of the Trustee such corporation or other entity shall be eligible under the provisions of Section 7.08. 
 In case at the time
such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor
trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent
appointed by such successor trustee may 

  
 39 












 
authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it
is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in
the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

Section 7.12 Trustee’s Application for Instructions from the Company. Any application by the Trustee for
written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set
forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken
by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer that the Company has
indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of
any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 

ARTICLE VIII 

CONCERNING THE HOLDERS 

Section 8.01 Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the
aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article IX, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders.
Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining Holders
entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 

Section 8.02 Proof of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and
Section 9.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06. 

  
 40 












 Section 8.03 Who Are Deemed Absolute Owners. The Company, the Trustee,
any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not
such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject
to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes under this Indenture; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar
shall be affected by any notice to the contrary. The sole registered holder of a Global Note shall be the Depositary or its nominee. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to
the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the
Notes following an Event of Default, any owner of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person,
such owner’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture. 

Section 8.04 Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal
amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee
shall be protected in conclusively relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be
regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary
thereof or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision or indecision by the Trustee taken
upon the advice of counsel shall be full protection to the Trustee. The Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the
account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed
therein are outstanding for the purpose of any such determination. 
 Section 8.05 Revocation of Consents; Future Holders
Bound. 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 percentage of the 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 at its Corporate Trust Office
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 Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or
substitution therefor or upon registration of transfer thereof.

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 9.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the

Section 9.07 No Delay of Rights by Meeting. Nothing contained in this Article IX shall be deemed or construed to authorize
or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the
Holders under any of the provisions of this Indenture or of the Notes. Nothing contained in this Article IX shall be deemed or construed to limit any Holder’s actions pursuant to the applicable procedures of the Depositary so long as the Notes

 With respect to clause (l) above, the supplemental indenture shall describe such conforming
changes to the Indenture. The Company shall deliver an Officer’s Certificate to the Trustee that the Company is entering into such supplemental indenture to conform the Indenture to the “Description of Notes” in such Offering

 44 












 Upon the written request of the Company, the Trustee is hereby authorized to join with the
Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental
indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any supplemental indenture
authorized by the provisions of this Section 10.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 

Section 10.02 Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article VIII) of
the Holders of at least a majority of the aggregate principal amount of Notes then outstanding (determined in accordance with Article VIII and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange
offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that,
without the consent of each Holder of an outstanding Note affected, no such supplemental indenture shall:

whose Holders must consent to an amendment; 
 (b) reduce the rate of or extend the stated time for payment of interest on any Note;

 Upon the
written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.05, 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. 

  
 45 












 Holders do not need, under this Section 10.02, to approve the particular form of any
proposed supplemental indenture. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall deliver to the Holders (with a copy to the Trustee) a notice briefly
describing such supplemental indenture. However, the failure to give such notice to all the Holders (with a copy to the Trustee), or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 

Section 10.03 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the
provisions of this Article X, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the
Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be
part of the terms and conditions of this Indenture for any and all purposes. 
 Section 10.04 Notation on Notes. Notes
authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article X may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental
indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 16.10) and delivered in exchange for the Notes
then outstanding, upon surrender of such Notes then outstanding. 
 Section 10.05 Evidence of Compliance of Supplemental Indenture
to Be Furnished Trustee. In addition to the documents required by Section 16.05, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed
pursuant hereto complies with the requirements of this Article X, is permitted or authorized by this Indenture and constitutes the legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms (which
Officer’s Certificate and Opinion of Counsel may contain customary exceptions and qualifications). 
 ARTICLE XI 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 11.01 Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 11.02, the Company
shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets substantially as an entirety to another Person, unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, all of the obligations of the
Company under the Notes and this Indenture; and 

  
 46 












 (b) immediately after giving effect to such transaction, no Default or Event of Default
shall have occurred and be continuing under this Indenture. 
 For purposes of this Section 11.01, the sale, conveyance, transfer or
lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all
of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

Section 11.02 Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance,
transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Notes, the due and punctual delivery or payment, as the
case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Company (if not the Company) shall
succeed to, and may exercise every right and power of, the Company under this Indenture, and the Company shall be discharged from its obligations under the Notes and this Indenture, except in the case of any such lease of all or substantially all of
the Company’s properties and assets. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been
signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall
deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to
be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article XI the Person
named as the “Company” in the first paragraph of this Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article XI) may be dissolved, wound up and liquidated at any time thereafter and,
except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes. 

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance)
may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 11.03 Evidence to Be Given to Trustee.
No consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Opinion of Counsel and an Officer’s Certificate to the effect that such transaction complies with the provisions of this
Article XI.

 ARTICLE XII 

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS,
EMPLOYEES OR STOCKHOLDERS 
 Section 12.01 Indenture and Notes Solely Corporate
Obligations. None of the Company’s past, present or future directors, officers, employees or stockholders, as such, will have any liability for any of the obligations under the Notes or this Indenture or for any claim based on, or in
respect or by reason of, such obligations or their creation. By accepting a Note, each Holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the Notes. 

ARTICLE XIII 

CONVERSION OF NOTES 

Section 13.01 Conversion Privilege. 

(a) Subject to and upon compliance with the provisions of this Article XIII, 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(b), at any time prior to the
close of business on the Business Day immediately preceding May 1, 2028 under the circumstances and during the periods set forth in Section 13.01(b), and (ii) regardless of the conditions described in Section 13.01(b), on or
after May 1, 2028 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 147.1183 shares of Common Stock (subject to adjustment as provided
in Section 13.04, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 13.02, the “Conversion Obligation”). 

(b) (i) Prior to the close of business on the Business Day immediately preceding May 1, 2028, a Holder may surrender all or any portion of
its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading-Day period (the “Measurement Period”) in which the Trading Price per
$1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this Section 13.01(b)(i) for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price
of the Common Stock and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The
Company shall provide written notice to the Bid Solicitation Agent of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for
each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination, and the Company shall have no obligation
to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price) unless a Holder of at least $1,000,000 aggregate principal amount of Notes provides the Company with
reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at which time the Company shall (i) instruct the
three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price to deliver bids to the Bid Solicitation Agent and (ii) instruct the Bid Solicitation Agent (if other than the
Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of Notes in each case, 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 

  
 48 












 
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 the Bid Solicitation Agent and does not, when required to,
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) if the Company is acting as Bid Solicitation Agent and fails to obtain such bids, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be
less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the
Trustee and the Conversion Agent (if other than the Trustee) in writing. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the
product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing. 

(ii) If, prior to the close of business on the Business Day immediately preceding May 1, 2028, the Company elects to: 

(A) issue to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a
stockholder rights plan so long as such rights have not separated from the shares of Common Stock) entitling them, for a period of not more than 45 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 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 Company in good faith and in a commercially reasonably manner, 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, the Trustee and the Conversion Agent (if other than the Trustee) in writing at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance
or distribution (or, if later in the case of any such separation of rights issued pursuant to a stockholder rights plan, as soon as reasonably practicable after the Company becomes aware that such separation or triggering event has occurred or will
occur). Once the Company has given such notice, Holders may surrender all or any portion of their 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 (or in the case of a separation or triggering event, until the
20th Trading Day following the date of the Company’s notice), even if the Notes are not otherwise convertible at such time. For purposes of this Section 13.01(b)(ii)(A) and Section 13.04(b), in determining whether any rights, options
or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading-Day period
ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received
by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other 

  
 49 












 
than cash, to be determined by the Company in good faith and in a commercially reasonable manner. Notwithstanding the foregoing, Holders of the Notes may not convert their Notes pursuant to this
provision if they participate, at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described above without having to convert their Notes as if they held a
number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

(iii) If (A) 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 May 1, 2028, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 14.01 or (B) the
Company is a party to a Merger Event (other than a Merger Event that is solely for the purpose of changing the Company’s jurisdiction of organization that (x) does not constitute a Fundamental Change or a Make-Whole Fundamental Change and
(y) results in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of Common Stock of the surviving entity and such Common Stock becomes Reference Property for the Notes), that occurs prior to the
close of business on the Business Day immediately preceding May 1, 2028 (each such Fundamental Change, Make-Whole Fundamental Change or Merger Event, a “Corporate Event”), then all or any portion of a Holder’s Notes may be
surrendered for conversion at any time after the effective date of such Corporate Event until the earlier of (x) 35 Trading Days after the actual effective date of such Corporate Event or, if such Corporate Event also constitutes a Fundamental
Change, until the close of business on the Business Day immediately preceding the related Fundamental Change Repurchase Date and (y) the Scheduled Trading Day immediately preceding the Maturity Date. The Company shall notify Holders, the
Trustee and the Conversion Agent (if other than the Trustee) in writing within three Business Days following the date the Company publicly announces such Corporate Event, but in no event later than the actual effective date of such Corporate Event.

 (iv) Prior to the close of business on the Business Day immediately preceding May 1, 2028, all or any portion of a
Holder’s Notes may be surrendered for conversion at any time during any fiscal quarter commencing after the fiscal quarter ending on September 24, 2022 (and only during such fiscal quarter), if the Last Reported Sale Price of the Common
Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on, and including, 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. The Conversion Agent, on behalf of the Company, shall determine at the beginning of each fiscal quarter commencing after September 24, 2022 whether the Notes may be surrendered for conversion in
accordance with this clause (iv) and shall notify the Company and the Trustee if the Notes become convertible in accordance with this clause. 

(v) If the Company calls any or all of the Notes for Optional Redemption pursuant to Article XV, then a Holder of any Note
called for Optional Redemption may surrender all or any portion of such Notes for conversion at any time prior to the close of business on the Scheduled Trading Day prior to the Redemption Date, even if such Note called for Optional Redemption are
not otherwise convertible at such time. After that time, the right to convert on account of the Company’s delivery of a Notice of Redemption shall expire, unless the Company defaults in the payment of the Redemption Price, in which case a
Holder of the Notes called for Optional Redemption may convert its Notes (or any portion thereof) until the close of business on the Scheduled Trading Day immediately preceding the date on which the Redemption Price has been paid or duly provided
for. Notwithstanding the foregoing, if the Company calls less than all outstanding Notes for Optional Redemption and a Holder (including, for this 

  
 50 












 
purpose, the owner of a beneficial interest in a Global Note) is not able to reasonably determine, prior to the close of business on the 44th Scheduled Trading Day immediately preceding the
relevant Redemption Date, whether the Notes owned by such Holder (or beneficially owned by such owner of a beneficial interest, as applicable) are subject to such partial Optional Redemption (and, as a result thereof, convertible in accordance with
this Section 13.01(b)(v)) for any reason, then such Holder (or such owner of a beneficial interest, as applicable) shall be entitled to convert such Notes (or such beneficial interests, as applicable) after the date of the Notice of Redemption
until the close of business on the Scheduled Trading Day prior to the Redemption Date, regardless of whether such Notes (or such beneficial interests, as applicable) are subject to such partial Optional Redemption. After that time, the right to
convert Notes on account of the Company’s delivery of a Notice of Redemption shall expire, unless the Company defaults in the payment of the Redemption Price, in which case such Holder of the Notes (or such owner of a beneficial interest, as
applicable) called for such partial Optional Redemption may convert such Notes (or such beneficial interests, as applicable) until the Redemption Price has been paid or duly provided for. Any such conversion will be deemed to be of a Note called for
Optional Redemption for purposes of Section 13.03. The Trustee shall not be obligated to make any determination in connection with this Section 13.01(b)(v). 

Section 13.02 Conversion Procedure; Settlement Upon Conversion. (a) Except as provided in Section 13.03(b) and
Section 13.07(a), upon conversion of any Note, on the second Business Day immediately following the last Trading Day of the relevant Observation Period, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect
of each $1,000 principal amount of Notes being converted, a “Settlement Amount” equal to the sum of the Daily Settlement Amounts for each of the 40 Trading Days during the relevant Observation Period for such Note, together with
cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 13.02. 

(i) All conversions for which the relevant Conversion Date occurs on or after May 1, 2028 and all conversions for which
the relevant Conversion Date occurs after the issuance of a Notice of Redemption and prior to the related Redemption Date shall be settled using the same forms and amounts of consideration. 

(ii) Except for any conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Notice of
Redemption with respect to the Notes, but prior to the related Redemption Date, and any conversions for which the relevant Conversion Date occurs on or after May 1, 2028, the Company shall use the same forms and amounts of consideration for all
conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same forms and amounts of consideration with respect to conversions that occur on different Conversion Dates. 

(iii) If, in respect of any Conversion Date (or for conversions occurring after the issuance of a Notice of Redemption or on or
after May 1, 2028, as the case may be), the Company elects to settle all or a portion of its Conversion Obligation in excess of the principal portion of the Notes being converted in cash in respect of such Conversion Date (or such period, as
the case may be), the Company shall inform converting Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such election (the “Settlement Notice”) no later than the close of business on the Trading Day
immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs (x) after the date of after the date of issuance of a Notice of Redemption with


  
 51 












 
respect to the Notes and prior to the related Redemption Date, in such Notice of Redemption or (y) on or after May 1, 2028, no later than the close of business on the Scheduled Trading
Day immediately preceding May 1, 2028) and the Company shall indicate in such Settlement Notice the percentage of each share of Common Stock issuable upon conversion in excess of the principal portion of the Notes being converted that will be
paid in cash (the “Cash Percentage”). If the Company does not elect a Cash Percentage prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect a Cash Percentage with
respect to any conversion on such Conversion Date or during such period, and the Company shall settle its Conversion Obligation by paying cash in respect of the principal portion of the converted Notes and delivering shares of Common Stock in
respect of the remainder (other than cash in lieu of any fractional share), if any, of its Conversion Obligation in excess of the aggregate principal portion of the Notes being converted as set forth herein. 

(iv) The Daily Settlement Amounts (if applicable), the Daily Net Settlement Amounts (if applicable) and the Daily Conversion
Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts, the Daily Net Settlement Amounts or the Daily Conversion Values,
as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts, the Daily Net
Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no
responsibility for any such determination. 
 (b) Subject to Section 13.02(e), before any Holder of a Note shall be entitled to convert
a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the 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 13.02(h) and, if required, pay all transfer and similar taxes, if any as provided in Sections 13.02(d) or (e), and (ii) in the case of a Physical Note (1) complete, manually sign and
deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the
principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be
registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements
and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 13.02(h). The Trustee (and, if different, the Conversion Agent)
shall notify the Company of any conversion pursuant to this Article XIII on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a
Fundamental Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 14.02. 

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

  
 52 












 (c) A Note shall be deemed to have been converted immediately prior to the close of business
on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be
issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be
entitled in satisfaction of the Company’s Conversion Obligation. 
 (d) In case any Note shall be surrendered for partial conversion,
the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted
portion of the surrendered Note, without payment of any service charge by the converting Holder but with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or
that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue
of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to
deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately
preceding sentence. 
 (f) Except as provided in Section 13.04, no adjustment shall be made for dividends on any shares issued upon the
conversion of any Note as provided in this Article XIII. 
 (g) Upon the conversion of an interest in a Global Note, the Trustee, or the
Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any
Conversion Agent other than the Trustee. 
 (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid
interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but
not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion
of Notes, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of
the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the
close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such
payment shall be required (1) for conversions of Notes following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the
Business Day immediately following the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a 

  
 53 












 
Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts
exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date, any Fundamental Change Repurchase Date or Redemption Date,
in each case, shall receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date in cash, regardless of whether their Notes have been converted following such Regular Record Date. 

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

(j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of
delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the last Trading Day of the relevant Observation Period. For each Note surrendered for conversion, the full number of shares, if any, that shall be
issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period, and any fractional shares remaining after such computation shall be paid in cash. 

Section 13.03 Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental
Changes or Notice of Redemption. (a) If (i) the Effective Date (as defined below) of a Make-Whole Fundamental Change occurs prior to the Maturity Date or (ii) the Company gives a Notice of Redemption with respect to the Notes
and, in each case, a Holder elects to convert its Notes (or portions thereof) in connection with such Make-Whole Fundamental Change or Notice of Redemption, the Company shall, under the circumstances described below, increase the Conversion Rate for
the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”) as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with”
such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the
related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for subclause (i) of the proviso in clause (b) of the definition thereof, the 35th Trading Day
immediately following the Effective Date of such Make-Whole Fundamental Change). A conversion of Notes shall be deemed for these purposes to be “in connection with” a Notice of Redemption and solely with respect to Notes called for
Optional Redemption thereby (including, for the avoidance of doubt, in the case of a partial Optional Redemption, Notes (or beneficial interests in a Global Note, as applicable) deemed to be called for such partial Optional Redemption in the
circumstances described under Section 13.01(b)(v)) if the Notice of Conversion of the Notes is received by the Conversion Agent from, and including, the date of the Notice of Redemption until the close of business on the Business Day
immediately preceding the Redemption Date. In the event that a conversion in connection with an Optional Redemption would also be deemed to be in connection with a Make-Whole Fundamental Change, a Holder of the Notes to be converted will be entitled
to a single increase to the Conversion Rate with respect to the first to occur of the applicable date of the Notice of Redemption or the Effective Date of the applicable Make-Whole Fundamental Change, and the later event will be deemed not to have
occurred for purposes of this Section 13.03. 

  
 54 












 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental
Change pursuant to Section 13.01(b)(iii) or a Notice of Redemption, as applicable, the Company shall, pay or deliver, as the case may be, the Settlement Amount due in respect of such Notes in accordance with Section 13.02 based on the
Conversion Rate as increased to reflect the Additional Shares pursuant to the table below; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of
Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be
calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied
by such Stock Price. In such event, the Conversion Obligation will be determined and shall be paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the
Conversion Agent (if other than the Trustee) in writing of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective Date. 

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table
below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective, or the date of the Notice of Redemption, as the case may be (in each case, the “Effective Date”) and the price paid (or deemed to be
paid) per share of the Common Stock in the Make-Whole Fundamental Change or with respect to the Notice of Redemption, as the case may be (in each case, the “Stock Price”). If the holders of the Common Stock receive in exchange for
their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the
Last Reported Sale Prices of the Common Stock over the five Trading-Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change or the
date of the Notice of Redemption, as the case may be. The Company in good faith and in a commercially reasonable manner shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the
Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, during such five consecutive
Trading-Day period. 
 (d) The Stock Prices set forth in the column headings of the table below shall
be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of
which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be
adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 13.04. 

  
 55 












 (e) The following table sets forth the number of Additional Shares of Common Stock by which
the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 13.03 for each Stock Price and Effective Date set forth below:

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

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in
the table above, the number of Additional Shares by which the Conversion Rate for the Notes will be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock
Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year; 

(ii) if the Stock Price is greater than $23.00 per share (subject to adjustment in the same manner as the Stock Prices set
forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate for the Notes; and 

(iii) if the Stock Price is less than $5.13 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate for the Notes. 

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 194.9317 shares of Common Stock, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 13.04. 
 (f) Nothing in this Section 13.03 shall prevent
an adjustment to the Conversion Rate pursuant to Section 13.04 in respect of a Make-Whole Fundamental Change. 
 Section 13.04
Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of
the Notes participate (other than in the case of a share split or share combination or a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the
transactions described in this Section 13.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes
held by such Holder. 

  
 56 












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





 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the Effective
Date of such share split or share combination, as applicable;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date (before giving effect to any such dividend, distribution,
split or combination); and
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Any adjustment made under this Section 13.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the
type described in this Section 13.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b) If the Company issues to all or
substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a stockholder rights plan) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to
subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading-Day period ending on, and
including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula: 
  





 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;


  
 57 













					
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 13.04(b) shall be made successively whenever any such rights, options or warrants
are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such
rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
Ex-Dividend Date for such issuance had not occurred. 
 For purposes of this Section 13.04(b)
and Section 13.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the
10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of
Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be
determined by the Company in good faith and in a commercially reasonable manner. 
 (c) If the Company distributes shares of its Capital
Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding: 

(i)dividends, distributions or issuances (including share splits) as to which an adjustment was effected pursuant to Section 13.04(a) or
Section 13.04(b); 
 (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in
Section 13.04(d) shall apply; 
 (iii) except as otherwise provided for in this Section 13.04(c), rights issued pursuant to a
stockholder rights plan of the Company; 
 (iv) distributions of Reference Property in a transaction as to which an adjustment was effected
pursuant to Section 13.07; and 
 (v) Spin-Offs as to which the provisions set forth below in this Section 13.04(c) shall apply
(any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), 

  
 58 












 then the Conversion Rate shall be increased based on the following formula: 

 
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Company in good faith and in commercially reasonable manner) of the Distributed Property with respect to each outstanding share of the Common Stock on the
Ex-Dividend Date for such distribution.

 Any increase made under the portion of this Section 13.04(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. If any distribution of the type described in this portion of Section 13.04(c) is declared but not so paid or made, the Conversion Rate shall be
decreased to the Conversion Rate that would then be in effect if such distribution had not been declared. If the Company issues rights, options or warrants that are only exercisable upon the occurrence of certain triggering events, then the Company
shall not adjust the Conversion Rate pursuant to this Section 13.04 until the earliest of these triggering events occurs, and the Company shall readjust the Conversion Rate to the extent that any of these rights, options or warrants are not
exercised before they expire. In the case of any distribution of rights, options or warrants, to the extent any such rights, options or warrants expire unexercised, the Conversion Rate shall be immediately readjusted to the Conversion Rate that
would then be in effect had the increase made for the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, options or
warrants. 
 Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as
holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 13.04(c) by reference to the actual or
when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive
Trading-Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution. 

With respect to an adjustment pursuant to this Section 13.04(c) where there has been a payment of a dividend or other distribution on the
Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national
securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

  
 59 












 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last
Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading-Day period after, and
including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); provided that if there is no Last Reported Sale Price of the Capital
Stock or similar equity interest distributed to the holders of the Common Stock on such Ex-Dividend Date, the Valuation Period shall be the first ten consecutive Trading Day period after, and including, the
first date such Last Reported Sale Price is available; and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The increase to the Conversion Rate under the preceding paragraph shall occur at the close of business on the
last Trading Day of the Valuation Period; provided that for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, the reference in this Section 13.04(c) to “10”
shall be deemed replaced with such lesser number of Trading Days as have elapsed from, but including, the Ex-Dividend Date for such Spin-Off to, and including, such
Trading Day in determining the Conversion Rate as of such Trading Day of such Observation Period. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or made, the Conversion
Rate shall be immediately decreased, effective as of the date the Board of Directors determines not to pay or make such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared or announced. 
 (d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, the
Conversion Rate shall be adjusted based on the following formula: 
  
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.


  
 60 












 Any increase pursuant to this Section 13.04(d) shall become effective immediately after the open of
business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors
determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of 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 Conversion Rate in effect on the
Ex-Dividend Date for such cash dividend or distribution. 
 (e) If the Company or any of its
Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock that is subject to the then-applicable tender offer rules under the Exchange Act, other than an odd lot tender offer, to the extent that the cash and value of
any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next
succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 

 
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Company in good faith and in a commercially reasonable manner) paid or payable for shares of Common Stock purchased in such tender or exchange
offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such
tender or exchange offer);
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or
exchange offer); and


  
 61 













					
			
	SP'	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 The increase to the Conversion Rate under this Section 13.04(e) shall occur at the close of business on the 10th Trading
Day immediately following, and including, the Trading Day immediately following the date such tender or exchange offer expires; provided that for any Trading Day that falls within the relevant Observation Period for such conversion and within
the 10 Trading Days immediately following, and including, the Trading Day immediately following the expiration date of any tender or exchange offer, references in this Section 13.04(e) to “10” or “10th” shall be deemed
replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding such expiration date of such tender or exchange offer to, and including, such Trading Day in determining the Conversion Rate as of
such Trading Day. 
 If the Company or one of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender or exchange
offer described in this Section 13.04(e) but the Company, or such Subsidiary, is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the applicable Conversion Rate will be decreased to
be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that have been effected. 

(f) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities
convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities (including as consideration for a merger, purchase or similar transaction). 

(g) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 13.04, and to the extent
permitted by applicable law and subject to the applicable listing standards of the Nasdaq Global Select Market, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of
Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of the Nasdaq Global Select Market, the Company may (but is not required
to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the
Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such
notice shall state the increased Conversion Rate and the period during which it will be in effect. 
 (h) Except as described above in this
Article XIII and under Section 13.03, the Conversion Rate will not be required to be adjusted for any transaction or event. Without limiting the foregoing, the Conversion Rate will not be required to be adjusted: 

(i) upon the issuance of shares of Common Stock at a price below the Conversion Price or otherwise, other than any such
issuance described in Section 13.04(a), Section 13.04(b), or Section 13.04(c); 

  
 62 












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

(iii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or
future employee, director or consultant benefit or incentive plan or program of or assumed by the Company or any of the Company’s Subsidiaries; 

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

(v) upon the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction (including, without limitation, through any structured or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives), or other buy-back transaction, that is not a tender offer or exchange offer of the nature described under Section 13.04(e); 

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

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

The Company shall not make an adjustment pursuant to clauses (a), (b), (c), (d) or (e) of this Section 13.04 unless such adjustment
would result in a change of at least 1% of the then effective Conversion Rate. However, the Company shall carry forward any adjustment to the Conversion Rate that the Company would otherwise have to make and take that adjustment into account in any
subsequent adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with respect to the Notes (i) in connection with any subsequent adjustment to the Conversion Rate of at least 1% of the Conversion Rate
(when such carried-forward adjustments are taken into account), (ii) regardless of whether the aggregate adjustment is less than 1% of the applicable Conversion Rate, on each Trading Day of any Observation Period related to any conversion of
Notes and (iii) on the Effective Date of any Make-Whole Fundamental Change or Notice of Redemption, in each case, unless the adjustment has already been made. All calculations and other determinations under this Article XIII shall be made by
the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share. All calculations and other determinations under this Article XIII shall be made by the Company and shall be made to the
nearest one-ten thousandth (1/10,000) of a share. 
 (i) Whenever the Conversion Rate is adjusted as
herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts
requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without
inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate
and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to each Holder. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

  
 63 












 (j) For purposes of this Section 13.04, the number of shares of Common Stock at any
time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable
in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 (k) For purposes of this Section 13.04,
“Effective Date” means the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, reflecting the relevant share split or share combination, as applicable. 

Section 13.05 Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last
Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values, the Daily Net Settlement Amounts or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock Price for
purposes of a Make-Whole Fundamental Change or Optional Redemption), the Company shall, in good faith and in a commercially reasonable manner, make appropriate adjustments, without duplication in respect of any adjustment made pursuant to
Section 13.04, to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date
or expiration date of the event occurs, at any time during the period when such Last Reported Sale Prices, Daily VWAPs, Daily Conversion Values, the Daily Net Settlement Amounts or Daily Settlement Amounts are to be calculated. 

Section 13.06 Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but
unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming delivery of the maximum number of Additional Shares pursuant
to Section 13.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder). 

Section 13.07 Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 

(a) In the case of: 

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or
combination), 
 (ii) any consolidation, merger or combination involving the Company, 

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s
Subsidiaries substantially as an entirety or 
 (iv) any statutory share exchange, 

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including
cash or any combination thereof) (any such event, a “Merger Event”), then the Company, or the successor or purchasing company, as the case may be, will execute with the Trustee and without the consent of the Holders, a supplemental
indenture providing that, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be 

  
 64 












 
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; provided, however, that at and after the effective time of the
Merger Event the Conversion Obligation shall be calculated and settled in accordance with Section 13.02 such that (A) the amount otherwise payable in cash upon conversion of the Notes as set forth under Section 13.02 shall continue to
be payable in cash, (B) the Company shall continue to have the right to elect to determine the form of consideration to be paid or delivered, as the case may be, in respect of the remainder, if any, of the Conversion Obligation in excess of the
principal amount of the Notes being converted as set forth under Section 13.02, (C) the number of shares of Common Stock, if any, otherwise deliverable upon conversion of the Notes in accordance with Section 13.02 shall instead be
deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have received in such Merger Event and (D) the Daily VWAP shall be calculated based on the value of a unit of Reference
Property. 
 If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single
type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be the types and amounts of consideration actually received by
the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders
of the Common Stock receive only cash in such 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 pursuant to Section 13.03), 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 second Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the 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. 
 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 XIII. If, in the case of any Merger Event, the Reference
Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental
indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing,
including the provisions providing for the purchase rights set forth in Article XIV. 
 (b) In the event the Company shall execute a
supplemental indenture pursuant to subsection (a) of this Section 13.07, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or
property or asset that will comprise 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 deliver notice thereof to all
Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to
deliver such notice shall not affect the legality or validity of such supplemental indenture. 

  
 65 












 (c) The Company shall not become a party to any Merger Event unless its terms are consistent
with this Section 13.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash up to the aggregate principal amount of such Notes and cash, shares of Common Stock or a combination of cash
and shares of Common Stock, as applicable, in respect of the remainder, if any, of the Conversion Obligation in excess of the aggregate principal amount of such Notes as set forth in Section 13.01 and Section 13.02 prior to the effective
date of such Merger Event. 
 (d) The above provisions of this Section shall similarly apply to successive Merger Events. 

Section 13.08 Certain Covenants. (a) The Company covenants that any shares of Common Stock issued upon
conversion of Notes will be validly issued, fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

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

 Section 13.09 Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any
duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion
Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities
or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither
the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 13.07 relating either to the kind or amount of shares
of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 13.07 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated
to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 13.01(b) has
occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 13.01(b) with respect to the commencement or
termination of such conversion rights, on which notices 

  
 66 












 
the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such
event or at such other times as shall be provided for in Section 13.01(b). The Conversion Agent (if other than the Company or an Affiliate of the Company) shall have the same protection under this Section 13.09 as the Trustee. 

Section 13.10 Stockholder Rights Plans. To the extent that the Company has a rights plan in effect upon conversion of the
Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if
any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if prior to any conversion of Notes, the rights have separated from the shares of Common Stock in
accordance with the provisions of the applicable stockholder rights plan so that the Holders would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon conversion of the Notes, the Conversion Rate shall be adjusted
at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property as provided in Section 13.04(c), subject to readjustment in the event of the expiration, termination or
redemption of such rights. 
 Section 13.11 Exchange in Lieu of Conversion. (a) Notwithstanding anything herein to the
contrary, when a Holder surrenders Notes for conversion, the Company may, at its election, direct the Conversion Agent to deliver, on or prior to the Scheduled Trading Day immediately following the Conversion Date, such Notes to one or more
financial institutions designated by the Company for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution(s) must agree to pay and/or deliver, as the case may be, to such
Holder, in exchange for such Notes, the cash, shares of Common Stock or any combination thereof that would otherwise be due upon conversion, as provided in Section 13.02 (the “Conversion Consideration”) or such other amount
agreed to by the Holder and the designated financial institution(s). By the close of business on the Trading Day following the relevant Conversion Date, the Company shall notify the Holder surrendering Notes for conversion, the Trustee and the
Conversion Agent (if other than the Trustee) in writing that the Company made the exchange election and the Company shall notify the designated financial institution(s) of the relevant deadline for delivery of the Conversion Consideration and the
type of Conversion Consideration to be paid and/or delivered, as the case may be. 
 (b) Any Notes delivered to the designated financial
institution will remain outstanding subject to applicable Depositary procedures. If the designated financial institution(s) agree(s) to accept any Notes for exchange but do(es) not timely pay and/or deliver, as the case may be, the related
Conversion Consideration, or if such designated financial institution(s) do(es) not accept the Notes for exchange, the Company shall pay and/or deliver, as the case may be, the relevant Conversion Consideration as if the Company had not made an
exchange election. 
 (c) The Company’s designation of a financial institution to which the Notes may be submitted for exchange does not
require the financial institution to accept any Notes.

 ARTICLE XIV 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 14.01 Repurchase at Option of Holders Upon a Fundamental Change. (a) If a
Fundamental Change occurs at any time prior to the Maturity Date of the Notes, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that
is equal to $1,000 or a multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar Days or more than 35 calendar Days following the date of the Fundamental
Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase
Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of
accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article XIV. 

(b) Repurchases of Notes under this Section 14.01 shall be made, at the option of the Holder thereof, upon: 

(i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase
Notice”) substantially in the form set forth in Attachment 2 to the Form of Note, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global
Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental
Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the
Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 

The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state: 

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

(ii) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

 (iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this
Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate
Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change
Repurchase Notice contemplated by this Section 14.01 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 14.02. 

  
 68 












 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental
Change Repurchase Notice or written notice of withdrawal thereof. 
 (c) On or before the 20th Business Day after the occurrence of a
Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence
of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered
in accordance with the applicable procedures of the Depositary. Each Fundamental Change Company Notice shall specify: 
 (i)
the events causing the Fundamental Change; 
 (ii) the effective date of the Fundamental Change; 

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

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

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

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

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

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes; provided, however,
that, if the Notes are Global Notes, the Holders (and holders of a beneficial interest in such Global Notes) must comply with the applicable procedures of the Depositary. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 14.01. 
 At the Company’s written request
and upon 15 days prior notice (or such shorter period as shall be acceptable to the Trustee), the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the
text of such Fundamental Change Company Notice shall be prepared by the Company. 

  
 69 












 (d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at
the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by
the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in
the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of
the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 14.02 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 received by the Paying Agent in accordance with this Section 14.02 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 a multiple of $1,000; 
 provided,
however, that if the Notes are Global Notes, the notice must comply with the applicable procedures of the Depositary. 

Section 14.03 Deposit of Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other
Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase
Date 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 (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date) 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 14.01) 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 14.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to
the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in
excess of the Fundamental Change Repurchase Price. 

  
 70 












 (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, with respect to Notes that have been
properly surrendered for repurchase and have not been validly withdrawn in accordance with the provisions of this Indenture, (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). 
 (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 14.01, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered. 

Section 14.04 Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the
Company will, if required: 
 (a) comply with the provisions of any applicable tender offer rules under the Exchange Act; 

(b) file a Schedule TO or any other required schedule under the Exchange Act; and 

(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 XIV to be exercised in the time and in the manner specified in this Article XIV.
To the extent that the provisions of any securities laws or regulations enacted after the date the Company initially issues the Notes conflict with the provisions of this Article XIV relating to the Company’s obligations to purchase the Notes
upon a Fundamental Change, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under such provisions of this Article XIV by virtue of such conflict. 

ARTICLE XV 

OPTIONAL REDEMPTION 

Section 15.01 Optional Redemption. No sinking fund is provided for the Notes. Except as provided in clause (b), the Notes shall
not be redeemable by the Company prior to August 5, 2025. On or after August 5, 2025, the Company may redeem, at its option, (an “Optional Redemption”) for cash all or any part of the Notes, at the Redemption Price, if the
Last Reported Sale Price of the Common Stock has been at least 130% of the Conversion Price then in effect for at least 20 Trading Days (whether or not consecutive) during any 30 consecutive Trading Day period (including the last Trading Day of such
period) ending on, and including, the Trading Day immediately preceding the date on which the Company provides the Notice of Redemption in accordance with Section 15.02. The Company may not specify a Redemption Date with respect to an Optional
Redemption that falls on or after the 41st Scheduled Trading Day immediately preceding the Maturity Date. 
 Section 15.02 Notice of
Redemption. (a) In case the Company exercises its right to redeem all or, as the case may be, any part of the Notes pursuant to Section 15.01, it shall fix a date for redemption (each, a “Redemption Date”) and it or,
at its written request received by the Trustee not less than 5 Scheduled Trading Days prior to the delivery of a notice of such redemption (a “Notice of Redemption”) (or such shorter period of time as may be acceptable to the
Trustee), the Trustee, in the name of and at the expense of the Company, shall deliver or cause to be 

  
 71 












 
delivered the Notice of Redemption not less than 45 nor more than 60 Scheduled Trading Days prior to the Redemption Date to each Holder of Notes, the Conversion Agent (if other than the Trustee)
and the Paying Agent (if other than the Trustee); provided, however, that, if the Company shall give such notice, it shall also give written notice of the Redemption Date to the Trustee. The Redemption Date must be a Business Day. 

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

(i) the Redemption Date; 

(ii) the Redemption Price; 

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that
interest thereon, if any, shall cease to accrue on and after the Redemption Date; 
 (iv) the place or places where such
Notes are to be surrendered for payment of the Redemption Price; 
 (v) that Holders may surrender their Notes for conversion
at any time prior to the close of business on the Scheduled Trading Day immediately preceding the Redemption Date (unless the Company fails to pay the Redemption Price in which case a Holder may convert such Notes until the close of business on the
Scheduled Trading Day immediately preceding the date on which the Redemption Price has been paid or duly provided for); 

(vi) the procedures a converting Holder must follow to convert its Notes and the Cash Percentage; 

(vii) the Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with
Section 13.03; and 
 (viii) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes. 

A Notice of Redemption shall be irrevocable. 

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

  
 72 












 Section 15.03 Payment of Notes Called for Redemption. (a) If any Notice of
Redemption has been given in respect of the Notes in accordance with Section 15.02, the Notes called for redemption shall become due and payable on the Redemption Date at the place or places stated in the Notice of Redemption and at the
Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Notice of Redemption, the Notes shall be paid and redeemed by the Company at the Redemption Price. 

(b) Prior to the open of business on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a Subsidiary
of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 4.04(b), an amount of cash (in immediately available funds if deposited on the Redemption Date) sufficient to pay the Redemption Price of all
of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made on the Redemption Date. The Paying Agent shall, promptly after such payment and upon written
demand by the Company, return to the Company any funds in excess of the Redemption Price and any amounts due and owing to the Trustee or Paying Agent. 

Section 15.04 Restrictions on Redemption. The Company may not redeem any Notes on any date pursuant to this Article XV if
the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a Default
by the Company in the payment of the Redemption Price with respect to the Notes).

application or demand by the Company to the Trustee to take any action under any of the provisions of this Indenture, the Company shall, if requested by the Trustee, furnish to the Trustee an Officer’s Certificate and an Opinion of Counsel (to
the extent that the determination of compliance requires a legal conclusion, but not as to any determination that requires a conclusion with respect to factual matters) stating that such action is permitted by the terms of this Indenture and that
all conditions precedent thereto have been complied with. 
 Each Officer’s Certificate and Opinion of Counsel provided for, by or on
behalf of the Company in this Indenture and delivered to the Trustee with respect to compliance with this Indenture (other than the Officer’s Certificates provided for in Section 4.08) shall include (a) a statement that the Person
signing such certificate is familiar with the requested action and this Indenture; (b) a brief statement as to the nature and scope of the examination or investigation upon which the statement contained in such certificate is based; (c) a
statement that, in the judgment of such person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed judgment as to whether or not such action is permitted by this Indenture; and (d) a

 Section 16.06 Legal Holidays. In any case where any Interest Payment
Date, Fundamental Change Repurchase Date, Conversion Date, Redemption Date or Maturity Date is not a Business Day, then any action to be taken on such date need not be taken on such date, but may be taken on the next succeeding Business Day with the
same force and effect as if taken on such date, and no interest shall accrue in respect of the delay. 
 Section 16.07 No Security
Interest Created. Nothing in this Indenture or in the Notes, expressed or implied, shall be construed to constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect,
in any jurisdiction. 
 Section 16.08 Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or
implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Conversion Agent, any authenticating agent, any Note Registrar and their successors hereunder or the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture. 
 Section 16.09 Table of Contents, Headings, Etc. The table of contents and the titles and
headings of the articles and sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof. 

Section 16.10 Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its
behalf and subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Section 2.04, Section 2.05, Section 2.06,
Section 2.07, Section 10.04 and Section 14.03 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes. For all
purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the
Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee
hereunder pursuant to Section 7.08. 
 Any corporation or other entity into which any authenticating agent may be merged or converted
or with which it may be consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity succeeding to all or substantially
all the corporate trust business of any authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this Section, without the execution or filing of
any paper or any further act on the part of the parties hereto or the authenticating agent or such successor corporation or other entity. 

  
 75 












 Any authenticating agent may at any time resign by giving written notice of resignation to
the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time any authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice of such appointment to
the Company and shall deliver notice of such appointment to all Holders as the names and addresses of such Holders appear on the Note Register. 

The Company agrees to pay to the authenticating agent from time to time such compensation for its services as agreed in writing although the
Company may terminate the authenticating agent (if other than the Trustee), if it determines such authenticating agent’s fees to be unreasonable. 

The provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and this Section 16.10 shall be applicable
to any authenticating agent. 
 If an authenticating agent is appointed pursuant to this Section, the Notes may have endorsed thereon, in
addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 

__________________________, 
 as Authenticating Agent, certifies
that this is one of the Notes described 
 in the within-named Indenture.

Section 16.11 Execution in Counterparts. This Indenture may be executed in any number of counterparts, each of which shall
be an original, but such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of
this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. The words
“execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Indenture or any document to be signed in connection with this Indenture shall be deemed to include electronic
signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping
system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means. All notices, approvals, consents, requests and any communications hereunder must be in writing (provided that any such
communication sent to Trustee hereunder must be in the form of a document that is signed manually or by way of a digital signature provided by DocuSign or other electronic signature provider that the Company plans to use (or such other digital
signature provider as specified in writing to Trustee by the authorized representative), in English. Company agrees to assume all risks arising out of the use of using digital signatures and electronic methods to submit communications to Trustee,
including without limitation the risk of Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties. 

Section 16.12 Severability. In the event any provision of this Indenture or in the Notes shall be invalid, illegal or
unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired. 

  
 76 












 Section 16.13 Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

Section 16.14 Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of
its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that are consistent with accepted
practices in the banking industry to resume performance as soon as practicable under the circumstances. 
 Section 16.15
Calculations. Except as otherwise provided herein, the Company shall be responsible for making all calculations called for under the Notes. These calculations include, but are not limited to, determinations of the Last Reported Sale Prices of
the Common Stock, the Trading Price of the Notes (for purposes of determining whether the Notes are convertible as described in this Indenture), the Daily VWAPs, the Daily Net Settlement Amounts, the Daily Settlement Amounts, the Daily Conversion
Values, Redemption Prices, accrued interest payable on the Notes and the Conversion Rate of the Notes. The Company shall make all these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding
on Holders. The Company shall provide a schedule of its calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations
without independent verification. The Company will forward the Company’s calculations to any Holder upon the written request of that Holder at the sole cost and expense of the Company. 

Section 16.16 USA PATRIOT Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT
Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a
relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act.

 [FORM OF REVERSE OF NOTE] 

Infinera Corporation 
 3.75%
Convertible Senior Note due 2028 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 3.75% Convertible
Senior Notes due 2028 (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 August 8, 2022 (the
“Indenture”), between the Company and U.S. Bank Trust Company, National Association (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. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture. 

In the event of certain Events of Default (other than an Event of Default specified in Section 6.01(h) or Section 6.01(i) of the
Indenture with respect to the Company or any of its Significant Subsidiaries) shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate
principal amount of the 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 on the Fundamental Change Repurchase Date (if applicable), the Redemption Price on any Redemption Date (if applicable) and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a
Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

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

  
 A-7 












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

The Notes shall be redeemable at the Company’s option in accordance with the terms and subject to the conditions specified in the
Indenture. No sinking fund is provided for the Notes. 
 Upon the occurrence of a Fundamental Change, the Holder has the right, at such
Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the
Fundamental Change Repurchase Price. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during
certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is
$1,000 or a multiple thereof, into cash up to the principal amount hereof and cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, in respect of the remainder, if any, of the Company’s Conversion
Obligation hereof in excess of the principal amount hereof at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 

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