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 to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted
Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in
this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days
after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee in writing of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the
proposed payment of such Defaulted Amounts and the special record date therefor to be 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

whatsoever for the calculation of the Defaulted Amounts. 
 (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 written notice as may be required by such exchange or
automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Company with respect to the issuance, authentication and delivery of such Notes.

 Only such Notes as shall bear thereon a certificate of authentication substantially in the
form set forth on the Form 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 17.10), 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 at the date of the execution of this Indenture any such person was not such an Officer.

to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a
reasonable period of time. The Trustee is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with Section 4.02.

any Note to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such legends as may be required by this Indenture.

Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 

  
 17

satisfactory to the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing. 

No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note
Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a
result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer. 

None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to
exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any Notes, or a portion of any Note, surrendered
for repurchase (and not withdrawn) in accordance with Article 15 or (iii) any Notes selected for Optional Redemption in accordance with Article 16, except the unredeemed portion of any Note being redeemed in part. 

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 the nominee of the Depositary. The transfer and
exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on

CONVERSION OF THIS SECURITY HAVE 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 IMPINJ, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE

 19 












 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 AFFILIATE (AS DEFINED IN RULE 144 UNDER THE SECURITIES ACT) OF THE COMPANY OR PERSON THAT HAS BEEN AN AFFILIATE (AS DEFINED IN RULE 144
UNDER THE SECURITIES ACT) OF THE COMPANY DURING THE IMMEDIATELY PRECEDING THREE MONTHS MAY PURCHASE, OTHERWISE ACQUIRE OR HOLD THIS SECURITY OR A BENEFICIAL INTEREST HEREIN. 

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) (i) as to
which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that
continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, 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 (or deemed assigned) a restricted CUSIP number. The Restrictive Legend set forth above and affixed on any Note will be deemed, in accordance with the terms of the certificate representing such Note, to
be removed therefrom upon the Company’s delivery to the Trustee of written notice to such effect, without further action by the Company, the Trustee, the Holder(s) thereof or any other Person; at such time, such Note will be deemed to be
assigned an unrestricted CUSIP number as provided in the certificate representing such Note, it being understood that the Depositary of any Global Note may require a mandatory exchange or other process to cause such Global Note to be identified by
an unrestricted CUSIP number in the facilities of such Depositary. Without limiting the generality of any other provision of this Indenture, the Trustee will be entitled to receive an instruction letter from the Company before taking any action with
respect to effecting any such mandatory exchange or other process. 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 any proposed transfer of any Note is being made in compliance with the Securities Act and applicable state securities laws. 

  
 20 












 The Company shall be entitled to instruct the Custodian in writing to so surrender any
Global Note as to which any of the conditions set forth in clause (i) through (iii) of the immediately preceding sentence have been satisfied, 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 (or deemed assigned) a restricted CUSIP number. The Company shall promptly notify the Trustee in writing
upon the occurrence of the Resale Restriction Termination Date and promptly 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. Any exchange pursuant to the foregoing paragraph shall be in accordance with the Applicable Procedures. 
 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 exchange of a Global Note or a portion thereof for one
or more Physical Notes in accordance with the second immediately succeeding paragraph. 
 The Depositary shall be a clearing agency
registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of
Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. 
 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, subject to the Applicable Procedures, 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, an Opinion of Counsel 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 to 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. 

  
 21 












 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, or, in the case of clause (iii) of the immediately
preceding paragraph, the relevant beneficial owner, 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, redeemed 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, redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note
shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or
the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 
 None of the Company, the Trustee (including in its
capacity as Paying Agent) or any agent of the Company or the Trustee shall have any responsibility or liability for the payment of amounts to owners of beneficial interest in a Global Notes, 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. 

Neither the Company nor the Trustee shall have any responsibility or liability for any act or omission of the Depositary. All notices and
communications to be given to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made only to, or upon the order of, the registered Holder(s) (which shall be the Depositary or its nominee in the case of a
Global Note). 
 The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the Applicable
Procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners. 

(d) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Note shall bear
a legend in substantially the following form (unless 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 a Note that has 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 IMPINJ, INC. (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 THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT AND IS EFFECTIVE AT THE TIME OF
SUCH TRANSFER, OR 
 (C) TO A PERSON THAT YOU REASONABLY BELIEVE TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH
RULE 144A UNDER THE SECURITIES ACT, OR 
 (D) 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 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. 

  
 23 












 Any such Common Stock (i) as to which such restrictions on transfer shall have expired
in accordance with their terms, (ii) that 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
(iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, 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 that is owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company
at any time during the three months immediately preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of
the Securities Act in a transaction that results in such Note no longer being a “restricted security” (as defined under Rule 144). 

(f) Notwithstanding anything contained herein to the contrary, neither the Trustee nor the Note Registrar shall be responsible for
ascertaining whether any transfer complies with the registration provisions of, or exemptions from, the Securities Act, applicable state securities laws or other applicable law. 

(g) Neither the Trustee nor any agent shall have any responsibility or liability for any actions taken or not taken by the Depositary, and may
assume performance absent written notice to the contrary. 
 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 receipt of a Company Order, 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. 

  
 24 












 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, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required
in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. 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 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a
substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish
to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such
substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof. 
 Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact
that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be
subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement, payment, redemption, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the replacement, payment, redemption, conversion or repurchase of negotiable instruments or other securities without their surrender. 

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 receipt of a Company Order, 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. 

  
 25 












 Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company
shall cause all Notes surrendered for the purpose of payment at maturity, repurchase upon a fundamental change, redemption, registration of transfer or exchange or conversion, if surrendered to any Person that the Company controls, to be surrendered
to the Trustee for cancellation and they will no longer be considered outstanding under this Indenture upon their payment at maturity, repurchase upon a fundamental change, redemption, registration of transfer or exchange or conversion. All Notes
delivered to the Trustee shall be canceled promptly by it. Except for any Notes surrendered for registration of transfer or exchange, or as otherwise expressly permitted by any of the provisions of this Indenture, no Notes shall be authenticated in
exchange for any Notes surrendered to the Trustee for cancellation. The Trustee shall dispose of canceled Notes in accordance with its customary procedures. After such cancellation, the Trustee shall deliver a certificate of such cancellation to the
Company, at the Company’s written request in a Company Order. 
 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. 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,
or notice to, the Holders and notwithstanding Section 2.01, issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue date, the 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 a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s
Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law and without the consent of Holders,
and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or
through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company may, to the extent permitted by applicable law, reissue, resell or surrender to the Trustee for cancellation in accordance with
Section 2.08 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” (as defined under Rule 144) upon such reissuance or resale. Any Notes


  
 26 












 
that the Company may (or is required under this Indenture to) repurchase shall be considered outstanding for all purposes under this Indenture unless and until such time the Company surrenders
them to the Trustee for cancellation in accordance with Section 2.08 and, upon receipt of a written order from the Company, the Trustee shall cancel all Notes so surrendered. 

ARTICLE 3 

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 of the Company, shall execute such instruments reasonably requested by the Company acknowledging satisfaction and discharge of this Indenture and the Notes,
when Section 3.02 (i) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) have been delivered to the
Trustee for cancellation; or (ii) after the Notes have (x) become due and payable, whether on the Maturity Date, on any Fundamental Change Repurchase Date, any Redemption Date or otherwise and/or (y) been converted (and the related
consideration due upon conversion has been determined), the Company has deposited with the Trustee cash and/or has delivered to Holders shares of Common Stock, as applicable, (in the case of Common Stock, solely to satisfy the Company’s
Conversion Obligation) sufficient to pay all of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and Section 3.03 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 4 

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 Fundamental Change Repurchase Price or the Redemption Price, if applicable) of, the Settlement Amounts owed upon conversion on, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and
in the manner provided herein and in the Notes. 
 Section 4.02. Maintenance of Office or Agency. The Company will
maintain in the United States an office or agency 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 in respect of the Notes and this Indenture may be made. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made at the Corporate Trust Office. 

  
 27 












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

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate
Trust Office as a place where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (if applicable) or for conversion and where notices in respect of the Notes and this Indenture may be made,
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:

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

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

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; 
 provided, that a Paying Agent appointed as contemplated under Section 15.02(f) shall not be required to
deliver any such instrument. 

  
 28 












 The Company shall, on or before each due date of the principal (including the Fundamental
Change Repurchase Price or the Redemption Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price or the
Redemption Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee 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 Fundamental Change Repurchase Price or the Redemption Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside,
segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable) and accrued and unpaid interest so becoming due
and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price or the Redemption 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 law, any money or property deposited with the Trustee, the Conversion Agent or any
Paying Agent, or any money and shares of Common Stock then held by the Company, in trust for the payment of the principal (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable) of, accrued and unpaid interest on
and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable), interest or consideration due upon
conversion has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust and the Trustee shall have no further
liability with respect to such funds or property; 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, the Conversion Agent or such Paying
Agent with respect to such trust money, and all liability of the Company as trustee with respect to such trust money and shares of Common Stock, shall thereupon cease; provided, however, that the Trustee, Conversion Agent or such
Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in
The Borough of 

  
 29 












 
Manhattan, The City of New York, notice that such money and shares of Common Stock remain unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money and shares of Common Stock then remaining will be repaid or delivered to the Company. 

Section 4.05. Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence. 
 Section 4.06. Rule 144A Information Requirement and Annual
Reports. (a) At any time the Company is not subject to Section 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, upon written request, 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 facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. 

(b) The Company shall file with the Trustee, within 15 days after the same are required to be filed with the Commission, copies of any
documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the
Exchange Act). Notwithstanding the foregoing, the Company shall in no event be required to file with, or otherwise provide or disclose to, the Trustee or any Holder any information for which the Company is requesting (assuming such request has not
been denied), or has received, confidential treatment from the Commission, or 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 documents have been filed. 
 (c) Delivery of the reports, information 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, 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 provided by Rule 12b-25 or any successor rule under the Exchange Act and other than reports on Form 8-K), or the Notes are
not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at 

  
 30 












 
any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional
Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and
is continuing or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding). 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
specified in Section 2.05(c) has not been removed, the Notes are assigned a restricted CUSIP or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the
Company’s Affiliates at any time during the three months immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 380th day after the last date of original issuance of
the Notes, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the Restrictive Legend on the Notes has been removed in accordance with Section 2.05(c), the
Notes are assigned an unrestricted CUSIP and the Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately
preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes. The Restrictive Legend on the Notes shall be deemed removed pursuant to the terms of this Indenture as provided in Section 2.05(c),
and, at such time, the Notes will, pursuant to, and subject to the provisions of, such Section, be deemed assigned an unrestricted CUSIP number. However, for the avoidance of doubt, Global Notes will continue to bear Additional Interest pursuant to
this paragraph until such time as they are identified by an unrestricted CUSIP in the facilities of the Depositary therefor, as a result of completion of such Depositary’s mandatory exchange process or otherwise. 

(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. However, in no event shall any Additional Interest that may accrue as a result of the
Company’s failure 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), as described in Section 4.06(d), together with any Additional Interest payable at the Company’s election as the remedy for an Event of Default relating to the
Company’s failure to comply with its reporting obligations as set forth Section 4.06(b), accrue at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving rise to the
requirement to pay such Additional Interest. 

  
 31 












 (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.
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 and the Trustee shall not have any duty to verify the
Company’s calculation of Additional Interest. 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 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 within 30 days after an officer of the Company becomes aware of the occurrence of any
Event of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or proposing to take in respect thereof; provided that the Company
is not required to deliver such notice if such Event of Default or Default has been cured. 
 Section 4.09. Further Instruments and
Acts. Upon request of the Trustee, Paying Agent or Conversion Agent, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the
purposes of this Indenture.

(g) default by the Company or any Significant Subsidiary of the Company with respect to any mortgage, agreement or other instrument under
which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $40,000,000 (or its foreign currency 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
debt when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, in each case, after the expiration of any applicable grace period, if such acceleration shall not have been rescinded or

the Trustee by Holders of at least 25% in aggregate principal amount of Notes then outstanding in accordance with this Indenture; 
 (h) the
Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy,
insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or any substantial part of its property,
or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall
publicly admit in writing that it generally is not paying, or is unable to pay, its debts as they become due; or 
 (i) an involuntary case
or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or
other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such
involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive days. 
 Section 6.02.
Acceleration; Rescission and Annulment. If 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 

  
 34 












 
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 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 at such time) 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
(except with respect to any continuing defaults relating to nonpayment of principal or interest or with respect to the failure to deliver the consideration due upon conversion) 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 Default or Event of Default resulting from (i) the
nonpayment of the principal (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a
failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 
 Section 6.03. Additional
Interest. 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 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: (i) 0.25% per annum of the principal amount of the Notes outstanding for
each day during the period beginning on, and including, the date on 

  
 35 












 
which such Event of Default first occurs and ending on the earlier of (x) the date on which such Event of Default is cured or validly waived in accordance with this Article 6 and
(y) the 180th day immediately following, and including, the date on which such Event of Default first occurs and (ii) if such Event of Default has not been cured or validly waived prior to the 181st day immediately following, and
including, the date on which such Event of Default first occurs, 0.50% per annum of the principal amount of Notes outstanding for each day during the period beginning on, and including, the 181st day immediately following, and including, the date on
which such Event of Default first occurs and ending on the earlier of (x) the date on which the Event of Default is cured or validly waived in accordance with this Article 6 and (y) the 360th day immediately following, and including, the
date on which such Event of Default first occurs. 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),
subject to the second immediately succeeding paragraph. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes and shall accrue on all outstanding
Notes from, and including, the date on which the Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) first occurs to, and including, the 360th day thereafter (or such earlier
date on which such Event of Default is cured or validly waived in accordance with this Article 6). 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 validly waived in accordance with this Article 6 prior to such 361st day), such Additional Interest shall cease to accrue and the Notes shall be immediately subject to acceleration as provided in
Section 6.02. The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in
Section 4.06(b). 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 has elected to make such payment but does not pay the Additional Interest
when due, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 
 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 all Holders of the Notes, the Trustee and the Paying Agent in an
Officer’s Certificate (consistent with Section 4.06(h)) of such election on or before the open of business on the business day immediately succeeding the date on which such Event of Default first occurs. Upon the failure to timely give
such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 
 In no event shall Additional
Interest payable at the Company’s election as the remedy for an Event of Default relating to the Company’s failure to comply with its reporting obligations as set forth in Section 4.06(b), together with any Additional Interest that
may accrue as a result of the Company’s failure 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 provided by Rule 12b-25 or any successor rule under the Exchange Act and other than reports on Form 8-K), pursuant to Section 4.06(d), accrue at a
rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. The Trustee shall have no duty to calculate or verify the calculation
of Additional Interest. 

  
 36 












 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, the property of the Company, or in the event of any other judicial proceedings relative to the Company, or to the creditors or property of the
Company, 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, its creditors, or its 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. 

  
 37 












 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding. 
 All rights of action and of asserting claims under 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
collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and
stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the payment of all
amounts due the Trustee (in each of its capacities under this Indenture), including its agent and counsel, 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; 

  
 38 












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

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

Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if
applicable, the Fundamental Change Repurchase Price or the Redemption Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by
availing of any provision of 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 institute such action, suit or proceeding in its own name as Trustee hereunder; 

(c) such Holders shall have offered to the Trustee such security or indemnity satisfactory to Trustee against any loss, liability or expense
to be incurred therein or thereby; 
 (d) the Trustee for 60 days after its receipt of such notice, request and offer of such security or
indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 
 (e) no direction that, in the opinion of
the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day
period pursuant to Section 6.09, 

  
 39 












 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, each Holder shall have the contractual right to receive
payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due
upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, and the contractual right to institute suit for the enforcement of any such payment or delivery, as the case may be, on
or after such respective dates, shall not be amended without the consent of each Holder. 
 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 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements
contained in 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 6 or by law to the Trustee or to the Holders may be exercised from time
to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 
 Section 6.09. Direction of Proceedings and
Waiver of Defaults by Majority of Holders. Subject to the Trustee’s right to receive security or indemnity from the relevant Holders as described herein, 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 the Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this 

  
 40 












 
Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it
determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with
Section 8.04 may on behalf of the Holders of all of the Notes (x) waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the
principal (including any Fundamental Change Repurchase Price or Redemption Price, if applicable) 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 10 cannot be modified or amended without the consent of each Holder of an outstanding Note
affected; and (y) rescind any resulting acceleration of the Notes and its consequences if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default
(other than nonpayment of the principal of, and interest on, the Notes that have become due solely by such acceleration) have been cured or waived. 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. 
 Section 6.10. Notice of Defaults. The Trustee shall, after
the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, deliver to all Holders notice of such Default within 90 days after such Responsible Officer obtains such knowledge, unless such Defaults shall have been
cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable), or accrued and
unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as a Responsible Officer of the Trustee 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 

  
 41 












 
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 or the
Redemption Price, if applicable) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions
of Article 14.

the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; provided that 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 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 of which a Responsible Officer of the Trustee has written notice or actual knowledge and
after the curing or waiving of all Events of Default that may have occurred: 
 the duties and obligations of the Trustee
shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and 
 in the absence of bad faith and willful misconduct
on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of
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);

Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts;

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 relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

relating to payment) or notice effected by the Company or any Paying Agent (except in its capacity as Paying Agent pursuant to the terms of this Indenture) or any records maintained by any co-Note Registrar
with respect to the Notes; 
 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to 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; 

(g) 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 incurred thereon 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; 

(h) under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by the Notes; and 

(i) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or

refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of
Counsel. 
 (c) The Trustee may consult with counsel and require an Opinion of Counsel and any written or verbal advice of such counsel or
Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in reliance on such advice or Opinion of Counsel. 

(d) 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,

including any Person specified as so authorized in any such certificate previously delivered and not superseded. 
 (i) The Trustee shall
not be deemed to have notice of any Default or Event of Default (except in the case of a Default or Event of Default in payment of scheduled principal of, premium, if any, or interest on, any Note) unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact such a Default or Event of Default (and stating the occurrence of a 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. 
 (j) The Trustee shall not be responsible or liable for any action it takes or
omits to take in good faith which it reasonably believes to be authorized or within its rights or powers.

any liability in connection with the malfeasance or nonfeasance by such party. The Trustee shall not be responsible for any inaccuracy in the information obtained from the Company or for any inaccuracy or omission in the records which may result

actions taken or not taken by the Depositary.

Section 7.05. Monies and Shares of Common Stock to Be Held in Trust. All monies and shares of Common Stock received by the
Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money and shares of Common Stock held by the Trustee in trust hereunder need not be segregated from other funds except to the

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, 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 expenses, disbursements and advances incurred or made by the Trustee in accordance

 46 












 
incurred without gross negligence, willful misconduct or bad faith 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 (whether such claims arise by or against the Company or a third person), including the reasonable costs and expenses
of defending themselves against any claim of liability in the premises or enforcing the Company’s obligations hereunder. 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 and the compensation for the services are intended to constitute expenses of administration under any
bankruptcy, insolvency or similar laws.

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 or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and
established by an Officer’s Certificate and Opinion of Counsel delivered to the Trustee, and such Officer’s Certificate and Opinion of Counsel, 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. 

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 (as if the Trust Indenture Act were applicable hereto) 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.


  
 47 












 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. Upon receiving such notice of resignation, the Company shall promptly notify all Holders 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 resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 60 days after
the giving of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders and 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 (or since the date of this Indenture) 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 (or since the date of this Indenture) may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction at the expense of
the Company for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with
Section 8.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto, in which
case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 

  
 48 












 (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 deliver or cause to be delivered notice of the succession of such trustee hereunder to the Holders. If the Company fails to deliver such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such notice to be delivered 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.


  
 49 












 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 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 to the Company 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 notice that the Company has been deemed to have been given pursuant to Section 17.03, 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 8 

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 9, 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. 

  
 50 












 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 (including any
Fundamental Change Repurchase Price or Redemption Price, if applicable) of and (subject to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee
nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. 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 holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy,
authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of 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 Affiliate of 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 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 an Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to such
right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of 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.

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

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

Section 9.07. No Delay of Rights by Meeting. Nothing contained in this Article 9 shall be deemed or construed to authorize

Holders under any of the provisions of this Indenture or of the Notes. Nothing contained in this Article 9 shall be deemed or construed to limit any Holder’s actions pursuant to the Applicable Procedures so long as the Notes are Global Notes.

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 8) of
the Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 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 

  
 55 












 
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

dates expressed or provided for in the Notes or this Indenture; or 
 (i) make any change in this Article 10 that requires each

 Upon the written request of the Company, and
upon the filing with the Trustee of evidence of the consent of the requisite 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. 

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, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 

  
 56 












 Section 10.03. Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture pursuant to the provisions of this Article 10, 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.

conform, in the opinion of 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, upon receipt of a
Company Order, by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.10) 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 to Trustee. In addition to the documents
required by Section 17.05, 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 10 and
is permitted or authorized by this Indenture such Opinion of Counsel to include a customary legal opinion stating that such supplemental indenture is the valid and binding obligation of the Company, subject to customary exceptions and
qualifications. 
 ARTICLE 11 

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 the consolidated assets of the Company and the Company’s Subsidiaries, taken as a whole, to another Person (other than any such sale,
conveyance, transfer or lease to one or more of the Company’s direct or indirect wholly-owned Subsidiaries), 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; 

  
 57 












 (b) immediately after giving effect to such transaction, no Default or Event of Default
shall have occurred and be continuing under this Indenture; and 
 (c) if the Company is not the Successor Company, the Successor Company
shall have delivered to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, transfer or lease complies with this Indenture and that such supplemental indenture is
authorized or permitted by this Indenture and an opinion of counsel stating that the supplemental indenture is the valid and binding obligation of the Successor Company, subject to customary exceptions and qualifications. 

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, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid
interest on all of the Notes, the due and punctual delivery and/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, except in the case of a lease of all or substantially all of the consolidated assets of the Company and the Company’s Subsidiaries, taken as a whole,
shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part, and the Company shall be discharged from its obligations under the Notes and this Indenture (except in the case of a lease of
all or substantially all of the consolidated assets of the Company and the Company’s Subsidiaries, taken as a whole). 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 11 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 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under 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. Officer’s Certificate and Opinion of Counsel to Be Given to Trustee. If a supplemental
indenture is required pursuant to this Article 11 as a result of the Company not being the Successor Company, no such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive (and shall be
conclusively entitled to rely upon) an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption complies with the provisions of this
Article 11, and that the supplemental indenture is the valid, binding obligations of the Successor Company, enforceable against such Successor Company in accordance with its terms, such Opinion of Counsel to be subject to customary exception. 

ARTICLE 12 

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND
DIRECTORS

of the principal of or accrued and unpaid interest on, or the payment or delivery of consideration due upon conversion of, any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation,

 ARTICLE 13 

[INTENTIONALLY OMITTED] 

ARTICLE 14 

CONVERSION OF NOTES 

Section 14.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 14, each
Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the
conditions described in Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding February 15, 2027 under the circumstances and during the periods set forth in Section 14.01(b), and
(ii) regardless of the conditions described in Section 14.01(b), on or after February 15, 2027 and prior to the close of business on the second Scheduled Trading Day immediately 

  
 59 












 
preceding the Maturity Date, in each case, at an initial conversion rate of 9.0061 shares of Common Stock (subject to adjustment as provided in this Article 14, the “Conversion
Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.02, the “Conversion Obligation”). 

(b) (i) Prior to the close of business on the Business Day immediately preceding February 15, 2027, a Holder may surrender all or any
portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of
Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock on each such
Trading Day and the Conversion Rate on each such Trading Day (the “Trading Price Condition”). 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 (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the
definition of Trading Price, along with appropriate contact information for each, and the Company shall instruct the three independent nationally recognized securities dealers to deliver bids to the Bid Solicitation Agent. The Bid Solicitation Agent
(if other than the Company) shall have no obligation to solicit the Trading Price per $1,000 principal amount of Notes unless the Company has requested such solicitation, and the Company shall have no obligation to make such request (or, if the
Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes) unless a Holder of at least $2,000,000 aggregate principal amount of Notes provides the Company
with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the Conversion Rate on such
Trading Day, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) to solicit, or if the Company is acting as Bid Solicitation Agent, the Company shall solicit, such bids beginning on the next Trading Day
and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate and the Company shall instruct
the three independent nationally recognized securities dealers to deliver bids to the Bid Solicitation Agent. The Company shall determine the Trading Price per $1,000 amount of Notes in accordance with the bids solicited by the Bid Solicitation
Agent. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation Agent in writing to solicit bids when obligated as provided in the preceding sentence, or if the Company instructs the Bid
Solicitation Agent in writing to obtain bids and the Bid Solicitation Agent fails to make such solicitation, or (y) the Company is acting as Bid Solicitation Agent and the Company fails to make such solicitation when obligated as provided in
the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day
of such failure. If the Trading Price Condition has been met on any Trading Day, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing on


  
 60 












 
or within one Business Day of such Trading Day. If, at any time after the Trading Price Condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to
98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such Trading Day, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing
that the Trading Price Condition is no longer met and thereafter neither the Company nor the Bid Solicitation Agent (if other than the Company) shall be required to solicit bids again until another qualifying request is made as provided above.
Neither the Trustee nor the Conversion Agent shall have any duty to determine or verify the Company’s determination of whether the Trading Price Condition has been met. 

(ii) If, prior to the close of business on the Business Day immediately preceding February 15, 2027, 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 stockholders rights plan, so long as such rights have not separated from the shares of the Common Stock) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase
shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of
announcement of such issuance; or 
 (B) distribute to all or substantially all holders of the Common Stock the
Company’s assets, securities or rights to purchase securities of the Company (other than pursuant to a stockholders rights plan, so long as such rights have not separated from the shares of the Common Stock), which distribution has a per share
value, as reasonably determined by the Company, 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 (such
notification, the “Certain Distributions Notification”) (x) at least 48 Scheduled Trading Days prior to or (y) if in the Certain Distributions Notification the Company irrevocably elects Physical Settlement in respect of any
conversions with Conversion Dates that occur after delivery to the Holders of the Certain Distributions Notification until the Certain Distributions Conversion Period End Date, at least 10 Scheduled Trading Days prior to, in either case, the Ex-Dividend Date for such issuance or distribution (or, if later in the case 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, a Holder may surrender all or any portion of its Notes for conversion at any time until the earlier of (1) the close of business
on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place (such
earlier date and time, the “Certain Distributions Conversion Period End Date”). 

  
 61 












 Holders may not convert their Notes pursuant to this Section 14.01(b)(ii) if they participate (other
than in the case of a share split or share combination in respect of the Common Stock), 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 applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

(iii) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the
close of business on the Business Day immediately preceding February 15, 2027, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or if the Company is a party to a Share
Exchange Event (other than a Share Exchange Event that is solely for the purpose of changing the Company’s jurisdiction of organization that (x) does not constitute a Fundamental Change or a Make-Whole Fundamental Change and
(y) results in a reclassification, conversion or exchange of outstanding shares of the 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 February 15, 2027 (each such Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event, a “Corporate Event”), all or any portion of a Holder’s
Notes may be surrendered for conversion at any time from or after the effective date of the Corporate Event until the earlier of (x) 35 Trading Days after the effective date of such Corporate Event or, if such Corporate Event also constitutes a
Fundamental Change, until the close of business on the Business Day immediately preceding the related Fundamental Change Repurchase Date and (y) the second 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 as promptly as practicable, but in any event no later than the effective date of such Corporate Event. 

(iv) Prior to the close of business on the Business Day immediately preceding February 15, 2027, a Holder may surrender
all or any portion of its Notes for conversion at any time during any fiscal quarter commencing after the fiscal quarter ending on March 31, 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. 
 (v) Neither the Trustee nor the Conversion Agent shall have any obligation to make any
calculation or to determine whether the Notes may be surrendered for conversion or to notify the Company, the Depositary or any Holders if the Notes have become convertible. 

  
 62 












 (vi) If the Company calls any Note for redemption pursuant to Article 16,
then the Holder of the Note called for redemption may surrender such Note for conversion at any time prior to the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date (any such period, a “Redemption
Period”), even if such Note is not otherwise convertible at such time. After that time, the right to convert such Note on account of the Company’s delivery of the Redemption Notice shall expire, unless the Company defaults in the
payment of the Redemption Price, in which case a Holder of such Note may convert such Note (or a 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. 
 (vii) If the Company elects to redeem less than all of the outstanding Notes pursuant to
Section 16.01 and the Holder of any Note (or any owner of a beneficial interest in any Global Note) is reasonably not able to determine, before the close of business on the 44th Scheduled
Trading Day immediately before the relevant optional redemption date, whether such Note or beneficial interest, as applicable, is to be redeemed pursuant to such redemption, then such Holder or owner, as applicable, will be entitled to convert such
Note or beneficial interest, as applicable, at any time during the related Redemption Period, and each such conversion will be deemed to be of a Note called for redemption. The Trustee shall not be obligated to make any determination in connection
with the foregoing. 
 Section 14.02. Conversion Procedure; Settlement Upon Conversion. 

(a) Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall pay or
deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering
any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of
delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Combination Settlement”), at its election, as set forth in this Section 14.02. 

(i) All conversions for which the relevant Conversion Date occurs on or after February 15, 2027or during a Redemption
Period shall be settled using the same Settlement Method. 
 (ii) Except for any conversions for which the relevant
Conversion Date occurs during a Redemption Period and any conversions for which the relevant Conversion Date occurs on or after February 15, 2027, the Company shall use the same Settlement Method for all conversions with the same Conversion
Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates. 

  
 63 












 (iii) If, in respect of any Conversion Date (or the period described in the
third immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a written notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as
the case may be), the Company shall deliver such Settlement Notice to the Trustee, the Conversion Agent and converting Holders no later than the close of business on the second Trading Day immediately following the relevant Conversion Date (or, in
the case of any conversions for which the relevant Conversion Date occurs (i) during a Redemption Period, in the related Redemption Notice or (ii) on or after February 15, 2027, no later than February 15, 2027). If the Company
does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement for such conversion or during such period and the
Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. Such Settlement Notice shall specify the relevant
Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing
Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes to be
converted shall be deemed to be $1,000. Notwithstanding anything to the contrary in the foregoing, the Company shall be permitted to irrevocably elect Physical Settlement in any Certain Distributions Notification and any such election would be
applicable to conversions with Conversion Dates that occur after delivery to the Holders of the Certain Distributions Notification until the Certain Distributions Conversion Period End Date. By notice to Holders, the Trustee and the Conversion Agent
(if other than the Trustee), the Company may, prior to the close of business on the Scheduled Trading Day immediately preceding February 15, 2027, at its option, irrevocably elect to satisfy its Conversion Obligation through Combination
Settlement with a Specified Dollar Amount per $1,000 principal amount of Notes of at least $1,000 for all Conversion Dates occurring subsequent to delivery of such notice and for which another Settlement Method does not otherwise apply or is not
otherwise deemed to apply as set forth above. If the Company irrevocably elects Combination Settlement with an ability to continue to set the Specified Dollar Amount per $1,000 principal amount of Notes at or above a specific amount, the Company
will, after the date of such election, inform Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) of such Specified Dollar Amount no later than the related Conversion Date (or in the case of any conversions for
which the relevant Conversion Date occurs (i) during a Redemption Period, in the related Redemption Notice, or (ii) on or after February 15, 2027, no later than the close of business on the Scheduled Trading Day immediately preceding
February 15, 2027), or, if the Company does not timely notify Holders, the Trustee and the Conversion Agent (if other than the Trustee), such Specified Dollar Amount will be the specific amount set forth in the election notice or, if no
specific amount was set forth in the election notice, such Specified Dollar Amount will be $1,000 per $1,000 principal amount of Notes. 

  
 64 












 
Concurrently with providing notice to Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) of such election, the Company will promptly file a Current Report on
Form 8-K or issue a press release announcing that they have elected to irrevocably fix the Settlement Method. The irrevocable election will apply to all Note conversions on Conversion Dates occurring
subsequent to delivery of such notice; provided, however, that no such election will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note; provided, further, that any such election that is made during a
Redemption Period will not be applicable to conversions with Conversion Dates that occur during such Redemption Period. For the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend the Indenture or
the Notes, including pursuant to Section 10.02. However, the Company may nonetheless choose to execute such an amendment at its option. 

(iv) The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes
(the “Settlement Amount”) shall be computed as follows: 
 (A) if the Company elects to satisfy its
Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock equal to the
Conversion Rate in effect on the Conversion Date (plus cash in lieu of any fractional share of Common Stock issuable upon conversion); 

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company
shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive Trading Days during the related Observation
Period; and 
 (C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of
such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of
the 40 consecutive Trading Days during the related Observation Period (plus cash in lieu of any fractional share of Common Stock issuable upon conversion). 

(v) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the
Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any
fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of
delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 

  
 65 












 (b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to
convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the Applicable Procedures in effect at that time and, if required, pay funds equal to the interest payable on the next Interest Payment Date to
which such Holder is not entitled as set forth in Section 14.02(h) and, if required, pay all transfer or similar taxes, if any, pursuant to Section 14.02(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, PDF or other electronic transmission thereof) (a “Notice of Conversion”) at the office of the Conversion Agent
and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the
Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish
appropriate endorsements and transfer documents, (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (5) if required, pay all
transfer or similar taxes, if any, pursuant to Section 14.02(e). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice
of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change
Repurchase Notice in accordance with Section 15.03. 
 If more than one Note shall be surrendered for conversion at one time by the
same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 14.03(b) and Section 14.07(a), the Company shall pay or deliver, as the case may be, the
consideration due in respect of the Conversion Obligation on the second Business Day immediately following the relevant Conversion Date, if the Company elects to satisfy its Conversion Obligation through Physical Settlement, or on the second
Business Day immediately following the last Trading Day of the Observation Period, if the Company elects to satisfy its Conversion Obligation through any other Settlement Method. If any shares of Common Stock are due to a converting Holder, the
Company shall issue or cause to be issued, and deliver to such Holder, or such Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary, in
satisfaction of the Company’s Conversion Obligation. 

  
 66 












 (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, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge
required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue
of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests 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 14.04, no adjustment shall be made for dividends on any shares of Common Stock
issued upon the conversion of any Note as provided in this Article 14. 
 (g) Upon the conversion of an interest in a Global Note, the
Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected
through any Conversion Agent other than the Trustee. 
 (h) Upon conversion, a Holder shall not receive any separate cash payment for
accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid
interest, if any, to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited.
Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the
close of business on a Regular Record Date but prior to the open of business on the immediately following Interest Payment Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest
payable on such Notes on such Interest Payment Date notwithstanding the conversion. However, Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the


  
 67 












 
immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted on the corresponding Interest Payment Date (regardless
of whether the converting Holder was the Holder of record on the corresponding Regular Record Date); provided that no such payment shall be required (1) for conversions following the close of business on the Regular Record Date
immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment
Date; (3) 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 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 Redemption Date and any
Fundamental Change Repurchase Date described in clause (2) above 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, redeemed
and/or repurchased, as applicable, following such Regular Record Date. 
 (i) The Person in whose name the shares of Common Stock shall be
issuable upon conversion shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of
the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for
conversion. 
 (j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash
in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant
Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected (or is deemed to have elected) Combination Settlement, the full number of shares that shall be issued upon conversion
thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash. 

Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes or
During a Redemption Period. (a) If (i) the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, or
(ii) the Company issues a Redemption Notice and a Holder of the Notes called for redemption elects to convert such Notes called for redemption (or portion thereof) during the related Redemption Period, 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


  
 68 












 
deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Conversion Date occurs during the period from, and including, the Effective Date
of the Make-Whole Fundamental Change up to, and including, the close of business on the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a
Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change
Period”). A conversion of Notes will be deemed for these purposes to be “in connection with” a Redemption Notice if the Notice of Conversion of the Notes is received by the Conversion Agent from, and including, the date of the
Redemption Notice until the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date. For the avoidance of doubt, the Company will increase the Conversion Rate hereunder during the related Redemption Period
only with respect to conversions of Notes called (or deemed called) for redemption, and not for Notes not called (or deemed called) for redemption. Accordingly, if the Company elects to redeem less than all of the outstanding Notes as described in
Section 14.01, Holders of the Notes not called for redemption will not be entitled to an increased Conversion Rate for conversions of such Notes (on account of the Redemption Notice) during the applicable Redemption Period, except in the
limited circumstances set forth in Section 14.01. 
 (b) Upon surrender of Notes for conversion in connection with a Make-Whole
Fundamental Change pursuant to Section 14.01(b)(iii) or during a Redemption Period, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with
Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental
Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be
deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be
paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of Notes of the Effective Date of any Make-Whole
Fundamental Change in writing no later than five Business Days after such Effective Date. 
 (c) The number of Additional Shares, if any, by
which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) or the Redemption
Notice Date, as applicable, and the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change or on the Redemption Notice Date (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 

  
 69 












 
five consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change or the Redemption Notice Date, as the
case may be. In the event that a conversion during a Redemption Period 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 Redemption Notice Date 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 14.03. The
Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where
the Ex-Dividend Date, Effective Date (as such term is used in Section 14.04) or Expiration Date of the event occurs during such five consecutive Trading Day period. 

(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 14.04. 
 (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 14.03 for each Stock Price and Effective Date or Redemption Notice Date, as applicable, set forth below:

 The exact Stock Price and Effective Date or Redemption Notice Date 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 or Redemption
Notice Date, as the case may be, is between two Effective 

  
 70 












 
Dates or Redemption Notice Dates, as applicable, in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set
forth for the higher and lower Stock Prices and the earlier and later Effective Dates or Redemption Notice Dates, as applicable, based on a 365-day year; 

(ii) if the Stock Price is greater than $750.00 per share (subject to adjustment in the same manner as the Stock Prices set
forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii) if the Stock Price is less than $77.92 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 12.8336 shares of Common Stock, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 
 (f) Nothing in this Section 14.03 shall prevent
an adjustment to the Conversion Rate pursuant to Section 14.04 in respect of a Make-Whole Fundamental Change. 
 Section 14.04.
Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the
Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in
any of the transactions described in this Section 14.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands)
of Notes held by such Holder. 
 (a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on shares of the
Common Stock, or if the Company effects a share split or share combination in respect of the shares of 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 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, as applicable;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date, as applicable, before giving effect to such dividend,
distribution, share split or share combination; and
			
	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 14.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the
type described in this Section 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b) If the Company issues to all or
substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a stockholders rights plan) entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, to
subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day
immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula: 
  





 
 where, 
  

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


  
 72 












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

Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become
effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or
warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for
such issuance had not occurred. 
 For purposes of this Section 14.04(b) and for the purpose of Section 14.01(b)(i)(A), in
determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share that is less than such average of the Last Reported Sale Prices of the Common
Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall
be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Company. 

(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 14.04(a) or Section 14.04(b), (ii) except as otherwise described in Section 14.11, rights issued pursuant to any stockholders rights plan of the Company then in effect, (iii) dividends or distributions paid
exclusively in cash as to which the provisions set forth in Section 14.04(d) shall apply, (iv) dividends or distributions of Reference Property in exchange for or upon conversion of the Common Stock in a Share Exchange Event, and
(v) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock
or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 
  





 

  
 73 












 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) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such
distribution.

 Any increase made under the portion of this Section 14.04(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing
increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property
such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines
the “FMV” (as defined above) of any distribution for purposes of this Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same
period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for
such distribution. 
 With respect to an adjustment pursuant to this Section 14.04(c) where there has been a payment of a dividend or
other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for
trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

 
 



 

  
 74 












 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 holders of the Common Stock on such Ex-Dividend Date, the
“Valuation Period” shall be the first 10 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 (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references to “10” in
the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the
Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such
conversion and within the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the
Ex-Dividend Date of such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. If the
Ex-Dividend Date of the Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of
Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and
including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or made, the Conversion Rate shall be immediately decreased, effective as of the date the Board of Directors determines not to pay 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. 

  
 75 












 For purposes of this Section 14.04(c) (and subject in all respect to
Section 14.11), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under
certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable;
and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(c)
will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under
this Section 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or
warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and
Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise
by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect
thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have
been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate
shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders
of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of
such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 

For purposes of Section 14.04(a), Section 14.04(b) and this Section 14.04(c), if any dividend or distribution to which this
Section 14.04(c) is applicable also includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which
Section 14.04(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options
or warrants to which Section 14.04(b) is applicable (the “Clause B Distribution”), 
 then, in either case, (1) such dividend or
distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion
Rate adjustment required by this Section 14.04(c) with respect to such Clause C Distribution shall then be made, 

  
 76 












 
and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by
Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the
Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be
deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior
to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b). 

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



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	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.

 Any increase pursuant to this Section 14.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or
pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of
shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash
dividend or distribution. 

  
 77 












 (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 (the date such tender offer or exchange
offer expires, the “Expiration Date”); 

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 Expiration Date; 

AC    =      the aggregate value of all cash and any other consideration
(as determined by the Company) paid or payable for shares of Common Stock purchased in such tender or exchange offer; 
 OS0    =      the number of shares of Common Stock outstanding immediately prior to the Expiration Date (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 Expiration Date (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and 

SP’    =      the average of the Last Reported Sale Prices of the
Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date. 

The increase to the Conversion Rate under this Section 14.04(e) shall occur at the close of business on the 10th Trading Day immediately
following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion
Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “10” or “10th” in


  
 78 












 
the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Expiration Date of such tender or exchange offer and the Conversion Date in
determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and
within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed
replaced with such lesser number of Trading Days as have elapsed between the Expiration Date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Trading Day next
succeeding the date such tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in
the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such
tender or exchange offer expires to, and including, the last Trading Day of such Observation Period. 
 In the event that the Company or one
of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company is, or such Subsidiary is, permanently prevented by applicable law from consummating any such purchases, or all
such purchases are rescinded, then the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that have
been consummated. 
 (f) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if a Conversion Rate
adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record
Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 14.02(i) based on an adjusted Conversion Rate for such Ex-Dividend
Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder.
Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 

(g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of the Common Stock or any securities
convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. 

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent
permitted by applicable law and subject to the applicable rules of 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 

  
 79 












 
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 of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is
increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder, the Trustee and the Conversion Agent 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. 
 (i) Except as stated
in this Indenture, 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. For illustrative purposes only and without limiting the generality of the preceding sentence, the Conversion Rate shall not 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 14.04(a), (b) or (c); 
 (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 plan or incentive plan (including pursuant to any evergreen plan) or program of or assumed by the Company or any of the Company’s Subsidiaries or in connection with any such shares withheld by the
Company for the withholding purposes; 
 (iv) upon the issuance of any shares of the Common Stock pursuant to any option,
warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued; 

(v) for tender offer by any party other than a tender offer by the Company or one or more of its Subsidiaries as described in
Section 14.04(d); 
 (vi) 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 transactions, that is not a tender offer or exchange offer of the nature described in Section 14.04(e); 

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

  
 80 












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

(j) The Company will not adjust the applicable Conversion Rate pursuant to the clauses (a), (b), (c), (d) or (e) of this
Section 14.04 unless the adjustment would result in a change of at least 1% in the then effective Conversion Rate. However, the Company will carry forward any adjustment to such 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) when all such deferred adjustments would result in an aggregate
change of at least 1% to the Conversion Rate; (ii) the Conversion Date of (if Physical Settlement applies to such conversion), or each Trading Day of the applicable Observation Period for (if Cash Settlement or Combination Settlement applies to
such conversion), any Note; and (iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs. All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. 
 (k) Whenever the Conversion Rate is adjusted as herein
provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring
such adjustment. Neither the Trustee nor the Conversion Agent shall have any responsibility to verify the accuracy of any adjustment to the Conversion Rate. 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. 
 (l)
For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any
distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

Section 14.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last
Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental
Change or Optional Redemption), the Company shall make appropriate adjustments (without duplication in respect of any adjustment made pursuant to Section 14.04) to each to account for any adjustment to the Conversion Rate that becomes
effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or Expiration Date, as the case may be, of the event occurs, at any time during the period when
the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 

  
 81 












 Section 14.06. Shares to Be Fully Paid. The Company shall reserve, 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 14.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable). 

Section 14.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 

(a) In the case of: 

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

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

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including
cash or any combination thereof) (any such event, a “Share Exchange Event”), then at and after the effective time of such Share Exchange Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right
to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the
Conversion Rate immediately prior to such Share Exchange Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference
Property that a holder of one share of Common Stock is entitled to receive) upon such Share Exchange Event and, prior to or at the effective time of such Share Exchange Event, the Company or the successor or acquiring Person, as the case may be,
shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective
time of the Share Exchange Event (A) the Company or the successor or acquiring company, as the case may be, shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of
Notes in accordance with Section 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in cash, (II) any shares of


  
 82 












 
Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of
Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Share Exchange Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 

If the Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of
consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of
Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders of the Common
Stock receive only cash in such Share Exchange Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Share Exchange Event (A) the consideration due upon conversion of each $1,000
principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.03), multiplied by the price paid per share of
Common Stock in such Share Exchange Event and (B) the Company shall satisfy the Conversion Obligation by paying such cash amount to converting Holders on the 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 reasonably practicable after such determination is made. 

If the Reference Property in respect of any Share Exchange Event includes, in whole or in part, shares of common equity, 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 14 with respect to the portion
of the Reference Property consisting of such common equity. If, in the case of any Share Exchange Event, the Reference Property includes shares of stock, securities or other property or assets (other than cash and/or cash equivalents) of a Person
other than the successor or purchasing corporation, as the case may be, in such Share Exchange Event, then such supplemental indenture shall also be executed by such other Person, if such other Person is an affiliate of the Company or the successor
or acquiring company, and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing. 

(b)    When the Company executes a supplemental indenture pursuant to subsection (a) of this Section 14.07, 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 Share
Exchange 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 delivered to each Holder within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

  
 83 












 (c)    The Company shall not become a party to any Share Exchange Event
unless its terms are consistent with this Section 14.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as
applicable, as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Share Exchange Event. 

(d)    The above provisions of this Section shall similarly apply to successive Share Exchange Events. 

Section 14.08. Certain Covenants. (a) Subject to Sections 14.02(d) and 14.02(e), the Company covenants that all shares
of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(b)    The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes
hereunder require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and
interpretations of the Commission, secure such registration or approval, as the case may be. 
 (c)    The Company
further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company will list and use its commercially reasonable efforts to keep listed, so long as the Common Stock
shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes. 

Section 14.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any
duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other 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 

  
 84 












 
Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the
kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 7.01, 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 14.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor. The Trustee and the Conversion Agent may conclusively rely upon any notice with respect to the commencement or termination of such
conversion rights, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). Except as
otherwise expressly provided herein, neither the Trustee nor any other agent acting under this Indenture (other than the Company, if acting in such capacity) shall have any obligation to make any calculation or to determine whether the Notes may be
surrendered for conversion pursuant to this Indenture, or to notify the Company or the Depositary or any of the Holders if the Notes have become convertible pursuant to the terms of this Indenture. 

Section 14.10. Notice to Holders Prior to Certain Actions. In case of any: 

(a)    action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant
to Section 14.04 or Section 14.11; 
 (b)    Share Exchange Event (other than with respect to any Share
Exchange Event for which notice is provided to under Section 14.01(b)(iii) of this Indenture); or 

(c)    voluntary or involuntary dissolution, liquidation or winding-up of the
Company; 
 then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture) and to
the extent applicable, the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder, a notice stating the date on which a record is to be taken for the purpose of such
action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries. Failure
to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Share Exchange Event, dissolution, liquidation or winding-up.

 Section 14.11. Stockholder Rights Plans. If the Company has a stockholder rights plan in effect upon conversion of the
Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, under such stockholder rights plan and the certificates representing the Common Stock issued upon such


  
 85 












 
conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to
any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company
distributed to all or substantially all holders of the Common Stock Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

Section 14.12. Exchange in Lieu of Conversion. When a Holder surrenders its Notes for conversion, the Company may, at its
election (an “Exchange Election”), cause such Notes to be delivered on or prior to the first Trading Day following the Conversion Date to a financial institution designated by the Company for exchange in lieu of conversion. In order
to accept any Notes surrendered for conversion, the designated financial institution must agree to timely deliver, in exchange for such Notes, the cash, shares of Common Stock or combination thereof due upon conversion as described in
Section 14.02. If the Company makes an Exchange Election, the Company shall, by the close of business on the first Trading Day following the relevant Conversion Date, notify in writing the Trustee, the Conversion Agent and the Holder
surrendering its Notes for conversion that it has made the Exchange Election, and the Company shall notify the designated financial institution of the Settlement Method it has elected with respect to such conversion and the relevant deadline for
payment and/or delivery of cash, shares of Common Stock or a combination thereof due upon conversion. The Company, the Holder surrendering its Notes for conversion, and the Conversion Agent shall cooperate to cause such Notes to be delivered to the
financial institution, and the Conversion Agent shall be entitled to conclusively rely upon the Company’s instruction in connection with effecting such Exchange Election and shall have no liability in respect of such Exchange Election outside
its control. 
 Any Notes exchanged by the designated financial institution, subject to Applicable Procedures, shall remain outstanding,
notwithstanding the surrender thereof by the Holder of such Notes. If the designated financial institution agrees to accept any Notes for exchange but does not timely pay and/or deliver the required cash, shares of Common Stock or a combination
thereof due upon conversion, or if such designated financial institution does not accept the Notes for exchange, the Company shall notify the Trustee, the Conversion Agent (if other than the Trustee) and the Holder surrendering its Notes for
conversion, and pay and/or deliver the required cash, shares of Common Stock or a combination thereof due upon conversion to the converting Holder at the time and in the manner required under this Indenture as if the Company had not made an Exchange
Election. 
 The Company’s designation of a financial institution to which the Notes may be submitted for exchange does not require
that financial institution to accept any Notes (unless the financial institution has separately made an agreement with the Company). The Company may, but shall not be obligated to, enter into a separate agreement with any designated financial
institution that would compensate it for any such transaction.

 ARTICLE 15 

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

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at
any time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple
of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 Business Days or more than 35 Business Days following the date of the Fundamental Change Company Notice at a
repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the
Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest
(to, but excluding, such Interest Payment Date) to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15.
The Fundamental Change Repurchase Date shall be subject to postponement in order to allow the Company to comply with applicable law. 
 (b)
Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon: 
 (i) delivery
to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in
compliance with the Applicable Procedures 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 office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the Applicable Procedures, in each
case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 
 The Fundamental Change
Repurchase Notice in respect of any Notes to be repurchased shall state: 
 (i) in the case of Physical Notes, the
certificate numbers of the Notes to be delivered for repurchase; 

  
 87 












 (ii) the portion of the principal amount of Notes to be repurchased, which
must be in minimum denominations of $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 the Applicable Procedures. 
 Notwithstanding anything herein to the
contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior
to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03. 

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

(i) the events causing the Fundamental Change; 

(ii) the effective date of the Fundamental Change; 

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

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

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

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

  
 88 












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

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02. 
 At the Company’s request, given at
least five days prior to the date the Fundamental Change Company Notice is to be sent to the Holders (or such shorter period as agreed by the Paying Agent) the Paying Agent shall give such notice in the Company’s name and at the Company’s
expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders in connection with 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 Applicable Procedures shall be deemed to
have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

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

 (f) For purposes of this Article 15, the Paying Agent may be any agent, depositary, tender agent, paying agent or other agent appointed
by the Company to accomplish the purposes set forth herein. 

  
 89 












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

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is
being submitted, and 
 (iii) the principal amount, if any, of such Note that remains subject to the original Fundamental
Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that
if the Notes are Global Notes, the notice must comply with Applicable Procedures of the Depositary. 
 Section 15.04. Deposit of
Fundamental Change Repurchase Price. (a) The Company will deposit with the Paying Agent, 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 (subject to extension in order to allow the Company to comply with applicable law) 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 Paying Agent, 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 (provided the Holder has satisfied the conditions in Section 15.02) and (ii) the time of book-entry transfer or the
delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 15.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the 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 Paying Agent shall, promptly after such payment and upon written
demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price. 
 (b) If by 11:00 a.m. New
York City time, on the Fundamental Change Repurchase Date, the Paying Agent holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, or, if extended in order
to allow the Company to comply with applicable law, such later date, then, with respect to the Notes that have been properly surrendered for repurchase and have not been validly withdrawn, (i) such Notes will cease to be outstanding,
(ii) interest will cease to accrue on such Notes on the Fundamental Change Repurchase Date or, if extended in order to allow the Company to comply with applicable law, such later date (whether or not book-entry transfer of the Notes has been
made or the Notes have been delivered to the Paying Agent) and (iii) all other rights of the Holders of such Notes with respect to the Notes will terminate on the Fundamental 

  
 90 












 
Change Repurchase Date or, if extended in order to allow the Company to comply with applicable law, such later date (other than (x) the right to receive the Fundamental Change Repurchase
Price and (y) if the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the related Interest Payment Date, the right of the Holder of record on such Regular Record Date to receive the full amount of accrued
and unpaid interest to, but excluding, such Interest Payment Date). 
 (c) Upon surrender of a Physical Note that is to be repurchased in
part pursuant to Section 15.02, the Company shall execute and the 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 15.05. 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 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 in all material respects with all federal and state securities laws in connection with any offer by the Company to
repurchase the Notes; 
 in each case, so as to permit the rights and obligations under this Article 15 to be exercised in the time and in the manner
specified in this Article 15 subject to postponement in order to allow the Company to comply with applicable law. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture relating to the
Company’s obligations to purchase the Notes upon a Fundamental Change, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under such provisions of this Indenture
by virtue of such conflict. 
 ARTICLE 16 

OPTIONAL REDEMPTION 

Section 16.01. Optional Redemption. No sinking fund is provided for the Notes. The Notes shall not be redeemable by the Company
prior to November 20, 2024. On or after November 20, 2024, the Company may redeem, at its option (subject to the Partial Redemption Limitation) (an “Optional Redemption”), for cash all or any portion 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 Redemption Notice (a “Redemption Notice Date”) in accordance with Section 16.02. 

Section 16.02. Notice of Optional Redemption; Selection of Notes. 

  
 91 












 (a) In case the Company exercises its Optional Redemption right to redeem all or, as the
case may be, any part of the Notes pursuant to Section 16.01, 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 five Scheduled Trading Days
prior to the Redemption Notice Date (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall deliver or cause to be delivered a notice of such Optional Redemption (a
“Redemption Notice”) not less than 45 nor more than 60 Scheduled Trading Days prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole or in part; provided, however, that, if the Company shall give
such notice, it shall also give written notice of the Redemption Date to the Trustee, the Conversion Agent (if other than the Trustee) and the Paying Agent (if other than the Trustee). The Redemption Date must be a Business Day. The Company may not
specify a Redemption Date that falls on or after the 41st Scheduled Trading Day immediately preceding the Maturity Date. 
 (b) The
Redemption Notice, if delivered in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice or any defect in the
Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. 

(c) Each Redemption Notice shall specify: 

(i) the Redemption Date; 

(ii) the Redemption Price; 

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

(vii) the Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with
Section 14.03; 

  
 92 












 (viii) the CUSIP, ISIN or other similar numbers, if any, assigned to such
Notes; and 
 (ix) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be
redeemed and on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued, which principal amount must be $1,000 or a multiple thereof. 

A Redemption Notice shall be irrevocable. 

(d) If the Company elects to redeem fewer than all of the outstanding Notes, at least $75.0 million aggregate principal amount of Notes
must be outstanding and not subject to redemption as of the relevant Redemption Date (such requirement, the “Partial Redemption Limitation”). If fewer than all of the outstanding Notes are to be redeemed, the Notes to be redeemed
will be selected according to the Depositary’s Applicable Procedures, in the case of Notes represented by a Global Note, or, in the case of Notes represented by Physical Notes, on a pro rata or by lot basis or by another method the Trustee
deems to be appropriate and fair. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be the portion
selected for redemption. 
 Section 16.03. Payment of Notes Called for Redemption. (a) If any Redemption Notice has been
given in respect of the Notes in accordance with Section 16.02, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and
surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price. 

(b) Prior to 11:00 a.m. New York City time on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a
Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 7.05 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 for such Notes. The Paying Agent shall, promptly after such
payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price. 
 Section 16.04
Restrictions on Redemption. The Company may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or
prior to the Redemption Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes).

 Section 17.06. Legal Holidays. In any case where any Interest Payment
Date, any Fundamental Change Repurchase Date, any Redemption Date or the 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

be closed will be deemed not to be a Business Day. 
 Section 17.07. 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 17.08. Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or implied, shall give to any
Person, other than the Holders, the parties hereto, any Paying Agent, any Conversion Agent, any Bid Solicitation Agent, any Custodian, any authenticating agent, any Note Registrar and their successors hereunder, any benefit or any legal or equitable
right, remedy or claim under this Indenture. 
 Section 17.09. 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 17.10. 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 15.04 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 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 17.10, 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. 

  
 96 












 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. 
 The Company agrees to pay to the authenticating agent from time
to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 

The provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and this Section 17.10 shall be applicable
to any authenticating agent. 
 If an authenticating agent is appointed pursuant to this Section 17.10, 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.

Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other similar state laws based on the Uniform Electronic Transactions Act; provided that, notwithstanding anything herein to the
contrary, the Trustee is under no obligation to agree to accept electronic signatures in any form or in any format unless expressly agreed to by the Trustee pursuant to reasonable procedures approved by the Trustee. All notices, approvals, consents,

as specified in writing to Trustee by the authorized representative) in English. The Company agrees to assume all risks arising out of the use of using digital signatures and electronic methods to submit communications to the Trustee, including
without limitation the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties. 

Section 17.12. 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. 

Section 17.13. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT

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 17.15. Calculations. 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 Daily VWAPs, the Trading Price of the Notes (for the purposes of determining whether the Notes are convertible as described
herein), the Daily Conversion Values, the Daily Settlement Amounts, adjustments to the Conversion Rate and the Conversion Price, accrued interest payable on the Notes, the Redemption Price, any Additional Interest payable and the Conversion Rate of
the Notes, including adjustments to the Conversion Price and the Conversion Rate. 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 of Notes.
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 of Notes upon the written request of that Holder at the sole cost and expense of the Company.

 Section 17.16. 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. 
 Section 17.17. Tax Withholding. The Company or the Trustee, as the case may be,
shall be entitled to make a deduction or withholding from any payment which it makes under this Indenture for or on account of any present or future taxes, duties or charges if and to the extent so required by any applicable law and any current or
future regulations or agreements thereunder or official interpretations thereof or any law implementing an intergovernmental approach thereto or by virtue of the relevant Holder failing to satisfy any certification or other requirements in respect
of the Notes, in which event the Company or the Trustee, as the case may be, shall make such payment after such withholding or deduction has been made and shall account to the relevant authorities for the amount so withheld or deducted and shall
have no obligation to gross up any payment hereunder or pay any additional amount as a result of such withholding tax.

 [FORM OF REVERSE OF NOTE] 

Impinj, Inc. 
 1.125% Convertible
Senior Note due 2027 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 1.125% Convertible Senior
Notes due 2027 (the “Notes”), limited to the aggregate principal amount of $287,500,000 all issued or to be issued under and pursuant to an Indenture dated as of November 5, 2021 (the “Indenture”), between the
Company and U.S. Bank 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 case certain Events of Default shall have
occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and
payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. 
 Subject to the
terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date, the Redemption Price on the Redemption Date and the principal
amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company 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. 

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

  
 A-6 












 The Notes are issuable in registered form without coupons in minimum 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 are not subject to redemption prior to November 20, 2024. The Notes shall be redeemable at the Company’s option on or
after November 20, 2024 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 integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. 

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of
certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into
cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
