to the account of the Depositary or its nominee.

interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: 

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective
Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall

notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt

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 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

the following clause (ii) of this Section 2.03(c). 
 (ii) The Company may make payment of any Defaulted Amounts in
any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or
automated quotation system, if, after 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.

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.

Transfer; Depositary. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note
Register”) in which, subject 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

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.

to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the
Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 
 All Notes presented or
surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be
accompanied by a written instrument or instruments of transfer in form satisfactory to the Note Registrar 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. 

  
 16 

 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 or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15. 

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.

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
transfer set forth herein) and the Applicable Procedures. 
 (c) Every Note that bears or is required under this Section 2.05(c) to

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

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 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. 

  
 18 

 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 to determine
that any proposed transfer of any Note is being made in compliance with the Securities Act and applicable state securities laws. 
 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 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. 
 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. 

  
 19 

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

 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 or transferred, such Global Note shall be, upon
receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical
Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance
with 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 or any agent of the Company or the
Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. 
 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). 

  
 20 

 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 OKTA, 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 

  
 21 

 (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 CLASS A 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. 
 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. 

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. 

  
 22 

 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, 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, 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

  
 23 

 
to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such
exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as
Physical Notes authenticated and delivered hereunder. 
 Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company shall
cause all Notes surrendered for the purpose of payment at maturity, registration of transfer or exchange or conversion, if surrendered to any Person that the Company controls other than the Trustee, to be surrendered to the Trustee for cancellation
and they will no longer be considered outstanding under this Indenture upon their payment at maturity, 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 resissuance or resale. Any Notes 

  
 24 

 
that the Company may 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 proper instruments acknowledging satisfaction and discharge of this Indenture and the Notes, when (a) (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 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 (b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of
this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive. 

ARTICLE 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, 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. 

  
 25 

 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.

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

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

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

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

(iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the
Trustee all sums so held in trust; 
 provided, that a Paying Agent appointed as contemplated under Section 15.02(f) shall not be required to
deliver any such instrument. 
 The Company shall, on or before each due date of the principal (including the Fundamental Change Repurchase
Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee 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. 

  
 26 

 (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, 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, 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, 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. 
 (d) Subject to applicable law, any money 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, 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, if applicable), interest or consideration due upon conversion has become due and payable shall be paid to the
Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee, 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 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 

  
 27 

 
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). 
 (c) Delivery of the reports and documents described in subsection (b) above to the Trustee
is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with
any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate). 
 (d) If, at
any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes, the Company fails to timely file any document or report that
it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form
8-K), or 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 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 

  
 28 

 
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 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. 
 (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. 
 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 January 31, 2019) 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.

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 or interest
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

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(i) or Section 6.01(j) with respect to the Company), unless the principal of all of the
Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, 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(i) or Section 6.01(j) with respect to the Company occurs and is continuing, 100% of the principal
of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable. 
 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 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 

  
 32 

 
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, 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 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. 

  
 33 

 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 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 thereunder 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. 
 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 

  
 34 

 
administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of
reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions,
dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 

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

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, including its agent and counsel, under Section 7.06; 

  
 35 

 Second, in case the principal of the outstanding Notes shall not have become due and be
unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such
interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto; 

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment
of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal
and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and
unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase 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 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 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 in its reasonable judgment 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, 

  
 36 

 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, 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. 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 

  
 37 

 
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 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) 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, 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

 38

accordance with the provisions of Article 14. 
 ARTICLE 7 

CONCERNING THE TRUSTEE 

Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing
or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. If an Event of Default has occurred and is continuing, the Trustee shall exercise such
of the rights and powers vested in it by this Indenture, and use 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 to the Trustee indemnity or security satisfactory to Trustee
in its reasonable judgment against any loss, liability or expense that might be incurred by it in compliance with such request or direction. 

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

(b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless
it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 

  
 39 

 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it
in good faith in accordance with the direction of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined as provided in Section 8.04 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; 

(d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording
protection to, the Trustee shall be subject to the provisions of this Section; 
 (e) the Trustee shall not be liable in respect of any
payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent (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; and 

(h) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or
transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or transfer agent. 

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 
 Section 7.02. Reliance
on Documents, Opinions, Etc. Except as otherwise provided in Section 7.01: 
 (a) The Trustee may conclusively rely and shall be fully
protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties. 

  
 40 

 (b) Any request, direction, order or demand of the Company mentioned herein shall be sufficiently
evidenced by an Officer’s Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary
of the Company. Before the Trustee acts 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
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,
and, if the Trustee shall determine in its reasonable judgment to make such further inquiry or investigation, it shall be entitled, at a reasonable time on any Business Day after reasonable notice, to examine the books, records and premises of the
Company, personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation. 

(e) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents,
custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney appointed by it with due care hereunder, and the permissive rights of the Trustee
enumerated herein shall not be construed as duties. 
 (f) The Trustee shall not be required to give any bond or surety in respect of the
execution of the trusts and powers under this Indenture. 
 (g) The Trustee may request that the Company deliver an Officer’s
Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any Person authorized to sign an
Officer’ Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

(h) 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. 

  
 41 

 (i) 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. 
 (j) The Trustee shall not be responsible or
liable for any action taken or omitted by it in good faith at the direction of the holders of not less than a majority in principal amount of the Notes as to the time, method and place of conducting any proceedings for any remedy available to the
Trustee or the exercising of any power conferred by this Indenture. 
 (k) Neither the Trustee nor any of its directors, officers,
employees, agents or affiliates shall be responsible for nor have any duty to monitor the performance or any action of the Company, or any of their respective directors, members, officers, agents, affiliates or employee, nor shall it have 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 from
such information or any failure by the Trustee to perform its duties as set forth herein as a result of any inaccuracy or incompleteness. 

(l) In no event shall the Trustee be responsible or liable for punitive, special, indirect or any consequential loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than any such loss or damage caused by the Trustee’s willful
misconduct or gross negligence. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of
Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or by any Holder of the Notes. 

(m) Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by the Depositary. 

Section 7.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s
certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of
the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 

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

  
 42 

 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 extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed from time to time by the Company and the Trustee. 

Section 7.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the
Trustee shall be entitled to, 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 with any of the provisions of this Indenture in any
capacity thereunder (including the compensation and the reasonable expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its
gross negligence, willful misconduct or bad faith. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any
authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense (including attorneys’ fees) 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 claim 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(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any
bankruptcy, insolvency or similar laws. 
 Section 7.07. Officer’s Certificate as Evidence. Except as otherwise provided
in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any

  
 43 

 
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 delivered to the Trustee, and such Officer’s Certificate, in the absence of gross negligence or willful misconduct on the part of the Trustee, shall
be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 

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. 

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, 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 

  
 44 

 
behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c)
The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, 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. 
 (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 claim 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. 

  
 45 

 Section 7.11. Succession by Merger, Etc. Any corporation or other entity
into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other
entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any
further act on the part of any of the parties hereto; provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be
eligible under the provisions of Section 7.08. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by
this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee,
and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may 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
the date any officer that the Company has indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking any
such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 

ARTICLE 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 

  
 46 

 
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. 
 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) 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. 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 

  
 47 

 and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the
above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding
for the purpose of any such determination. 
 Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but
not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder
of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section
8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued
in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer
thereof.

the Company. Such notices shall be delivered not less than 20 nor more than 90 days prior to the date fixed for the meeting. 

  
 48 

 Any meeting of Holders shall be valid without notice if the Holders of all Notes then outstanding

meeting, waived notice. 
 Section 9.03. Call of Meetings by Company or Holders. In case at any time the Company, pursuant to a Board

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 for such meeting and may call such
meeting to take any action authorized in Section 9.01, by delivering notice thereof as provided in Section 9.02.

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

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

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

  
 49 

 Section 9.06. Voting. The vote upon any resolution submitted to any meeting of Holders
shall be by written ballot on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the outstanding aggregate principal amount of the Notes held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the
meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken
thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was delivered as provided in Section 9.02. The record shall show the aggregate principal
amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the
other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 
 Any record so
signed and verified shall be conclusive evidence of the matters therein stated. 
 Section 9.07. No Delay of Rights by Meeting.
Nothing contained in this Article 9 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise
of any right or rights conferred upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Notes.

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 Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture, any supplemental indenture or the Notes or of modifying in any manner the rights of the Holders;

provided for in the Notes or this Indenture; or 
 (i) make any change in this Article 10 that requires each Holder’s consent or in the
waiver provisions in Section 6.02 or Section 6.09. 
 Upon the written request of the Company, and upon the filing with the
Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own
rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

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 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. 
 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, 

  
 52 

 limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the
Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms
and conditions of this Indenture for any and all purposes. 
 Section 10.04. Notation on Notes. Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so
determine, new Notes so modified as to conform, in the opinion of the Board of Directors, to any modification of 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 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, 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; 
 (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. 

  
 53 

 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. Opinion of Counsel to Be Given to Trustee. If a supplemental indenture is required pursuant to this Article 11, no such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an
Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption complies with the provisions of this Article 11.

of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration

 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 October 15, 2022 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 October 15, 2022 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 20.6795 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 October 15, 2022, 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. 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 

  
 55 

 
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. 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
to solicit bids when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent 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) on 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) 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. 

(ii) If, prior to the close of business on the Business Day immediately preceding October 15, 2022, 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 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; 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 Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement for such distribution, 

  
 56 

 then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if
other than the Trustee) (such notification, the “Certain Distributions Notification”) (x) at least 50 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. 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”). 
 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), 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 October 15, 2022, 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 October 15, 2022 (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) as promptly as practicable following the date the Company publicly announces the effective date of such Corporate Event,
but in no event later than the effective date of such Corporate Event. 

  
 57 

 (iv) Prior to the close of business on the Business Day immediately preceding
October 15, 2022, 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 April 30, 2018 (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. 
 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 October 15, 2022 shall be settled using the
same Settlement Method. 
 (ii) Except for any conversions for which the relevant Conversion Date occurs on or after
October 15, 2022, 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. 
 (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 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 Conversion Agent and converting Holders no later than the close of business on the first Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant
Conversion Date occurs on or after October 15, 2022, no later than October 15, 2022). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have
the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be
equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of
Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a 

  
 58 

 
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 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. 

(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. 

  
 59 

 (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 procedures of the Depositary 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 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 (if applicable) to the Conversion Agent or 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. 
 (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. 

  
 60 

 (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 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; or (3) 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 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 and/or
repurchased, as applicable, following such Regular Record Date. 

  
 61 

 (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 Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the
aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash. 

Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes. (a)
If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below,
increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for these
purposes to be “in connection with” such Make-Whole Fundamental Change if 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”). 

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

  
 62 

 
shall be paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify 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 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”) and the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change (the “Stock Price”). If the holders of the Common Stock receive in exchange for their
Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last
Reported Sale Prices of the Common Stock over the five consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. 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 set forth below:

 The exact Stock Price and Effective 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 is between two Effective Dates 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, as applicable, based
on a 365-day year; 

  
 63 

 (ii) if the Stock Price is greater than $150.00 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 $35.82 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 27.9173 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, 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;

  
 64 

					
	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;
			
	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.

  
 65 

 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)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price per share that is less than such average of the Last Reported
Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement 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 Board of Directors. 
 (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other
assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances (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: 

 
 

 
 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;

  
 66 

					
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date
for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such
distribution.

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

 
 

 
 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”); and

  
 67 

					
	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. 
 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

  
 68 

 
any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate
shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though
it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants),
made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate
shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of Section 14.04(a),
Section 14.04(b) and this Section 14.04(c), if any dividend or distribution to which this Section 14.04(c) is applicable also includes one or both of: 

(A) a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the “Clause A
Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable
(the “Clause B Distribution”), 
 then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and
the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 14.04(c)
with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by
Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the
Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be
deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior
to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b). 

(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;

  
 69 

					
	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. 
 (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 Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

  
 70 

					
	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 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 

  
 71 

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

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

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

  
 72 

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

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

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

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. 
 (k) Whenever the Conversion Rate is adjusted as herein
provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring
such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry
that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the
date on which each adjustment becomes effective and shall 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), the Board of Directors 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. 

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). 

  
 73 

 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 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 

  
 74 

 
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) 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, including the provisions providing for the purchase rights set forth in Article 15. 

(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. 

(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. 

  
 75 

 (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 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

  
 76 

 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). 

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; 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 no later than the earlier of the date
notice of such date is required to be provided under Rule 10b-17 of the Exchange Act, other applicable Commission rule or applicable rules of the principal U.S. national or regional securities exchange on
which the Common Stock is then listed or admitted for trading and such date is publicly announced by the Company. 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 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”), direct the Conversion Agent to deliver, on or prior to the first Trading Day following the Conversion Date, such Notes to a financial institution designated by the Company for exchange in
lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution must agree to timely deliver, in exchange for such Notes, the 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 

  
 77 

 
relevant Conversion Date, notify 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. 

Any Notes exchanged by the designated financial institution shall remain outstanding. If the designated financial institution agrees to accept
any Notes for exchange but does not timely pay and/or deliver the 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 Conversion Agent 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. 

  
 78 

 (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 procedures of the Depositary, in each case
such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 
 The Fundamental Change
Repurchase Notice in respect of any Notes to be repurchased shall state: 
 (i) in the case of Physical Notes, the
certificate numbers of the Notes to be delivered for repurchase; 
 (ii) the portion of the principal amount of Notes to be
repurchased, which must be $1,000 or an integral multiple thereof; and 
 (iii) that the Notes are to be repurchased by the
Company pursuant to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the
Fundamental Change Repurchase Notice must comply with 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 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; 

  
 79 

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

(v) the Fundamental Change Repurchase Date; 

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

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

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be
converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of 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. Simultaneously with providing such notice, the Company will publish such information on its website or through such other public medium as the Company
may use at that time. 
 At the Company’s request, 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. 

  
 80 

 (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. 
 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 $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 appropriate 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. 

  
 81 

 (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 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 our obligations under such provisions of this Indenture
by virtue of such conflict.

 86 

 
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,

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 Trustee will

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] 

Okta, Inc. 
 0.25% Convertible
Senior Note due 2023 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 0.25% Convertible Senior
Notes due 2023 (the “Notes”), limited to the aggregate principal amount of $345,000,000 all issued or to be issued under and pursuant to an Indenture dated as of February 27, 2018 (the “Indenture”), between the
Company and Wilmington Trust, 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 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, 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

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

The Notes are not subject to redemption through the operation of any sinking fund or otherwise. 

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase for
cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. 

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of
certain conditions specified in the Indenture, prior to the close of business on the 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.

 The purpose of this letter agreement (this
“Confirmation”) is to confirm the terms and conditions of the call option transaction entered into between [Dealer] (“Dealer”) and Okta, Inc. (“Counterparty”) as of the Trade Date specified

evidence a complete binding agreement between Counterparty and Dealer as to the subject matter and terms of the Transaction to which this Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with
respect thereto. 
 The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity
Definitions”), as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation. In the event of any inconsistency between the Equity Definitions and this
Confirmation, this Confirmation shall govern. Certain defined terms used herein are based on terms that are defined in the Offering Memorandum dated February [DATE], 2018 (the “Offering Memorandum”) relating to the
[    ]% Convertible Senior Notes due 2023 (as originally issued by Counterparty, the “Convertible Notes” and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by
Counterparty in an aggregate initial principal amount of USD [300],000,000 (as increased by [up to]1 an aggregate principal amount of USD [45],000,000 [if and to the extent that]2[pursuant to the exercise by]3 the Initial Purchasers (as defined herein) [exercise]4[of]5 their option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture [to be]6
dated [DATE], 2018 between Counterparty and [Wilmington Trust, National Association], as trustee (the “Indenture”). In the event of any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this
Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to
the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Offering Memorandum. If any such definitions in the Indenture or any such sections of the Indenture differ from the
descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation. The parties further acknowledge that the Indenture section numbers used herein are based on the
[draft of the Indenture last reviewed by Dealer as of the date of this Confirmation, and if any such section numbers are changed in the Indenture as executed, the parties will amend this Confirmation in good faith to preserve the intent of the

supplement (x) pursuant to Section 10.01(n) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering
Memorandum or (y) pursuant to Section 14.07 of the Indenture, subject, in the case of this clause (y), to the second paragraph under “Method of Adjustment” in Section 3), any such amendment or supplement will be disregarded
for purposes of this Confirmation (other than as provided in Section 9(h)(iii) below) unless the parties agree otherwise in writing. 

Each party is hereby advised, and each such party acknowledges, that the other party has engaged in, or refrained from engaging in,
substantial financial transactions and has taken other material actions in reliance upon the parties’ entry into the Transaction to which this Confirmation relates on the terms and conditions set forth below. 

1.This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation
relates. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Dealer and Counterparty had executed an agreement in such form (but
without any Schedule except for (i) U.S. Dollars (“USD”) as the Termination Currency, (ii) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement will apply to Dealer as if
(w) the phrase “, or becoming capable at such time of being declared,” were deleted from Section 5(a)(vi)(1) of the Agreement, (x) the “Threshold Amount” with respect to Dealer were three percent (3%) of
shareholders’ equity of [Dealer/Name of Dealer’s Parent] as of the Trade Date, (y) “Specified Indebtedness” had the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in
respect of deposits received in the ordinary course of Dealer’s banking business, and (z) the following language were added to the end of such Section 5(a)(vi): “Notwithstanding the foregoing, a default under subsection
(2) hereof shall not constitute an Event of Default if (1) the default was caused solely by error or omission of an administrative or operational nature; (2) funds were available to enable the party to make the payment when due; and
(3) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay.” and (iii) the election of the laws of the State of New York as the governing law (without reference to
choice of law doctrine)) on the Trade Date. In the event of any inconsistency between provisions of the Agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction to which this Confirmation relates. The
parties hereby agree that no transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement.

the Scheduled Valid Day immediately preceding the scheduled first day of the Settlement Averaging Period for the Options being exercised (the “Notice Deadline”) of (i) the number of such Options, (ii) the
scheduled first day of the Settlement Averaging Period and the scheduled Settlement Date, (iii) the Relevant Settlement Method for such Options, and (iv) if the settlement method for the related Convertible Notes is not Settlement in

pursuant to this proviso, the Calculation Agent shall have the right to (i) postpone the Settlement Date and (ii) adjust the number of Shares deliverable and/or amount of cash payable by Dealer with respect to such Options in a
commercially reasonable manner as appropriate to reflect the additional costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its commercially reasonable hedging activities as
a result of Dealer not having received such Notice of Exercise, on or prior to such Notice Deadline; provided further that in respect of any Options relating to Convertible Notes with a Conversion Date occurring on or after the Free
Convertibility Date, (A) such notice may be given on or prior to the second Scheduled Valid Day immediately preceding the Expiration Date and need only specify the information required in clause (i) above, and (B) if the Relevant
Settlement Method for such Options is (x) Net Share Settlement and the Specified Cash Amount is not USD 1,000, (y) Cash Settlement or (z) Combination Settlement, Dealer shall have received a separate notice (the “Notice of
Final Settlement Method”) in respect of all such Convertible Notes before 5:00 p.m. (New York City time) on the Free Convertibility Date specifying the

  
 4 

			
		
		  	information required in clauses (iii) and (iv) above. Counterparty acknowledges its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act (as defined
below) and the rules and regulations thereunder, in respect of any election of a settlement method with respect to the Convertible Notes.

discretion.
		
	 Market Disruption Event:
	  	Section 6.3(a) of the Equity Definitions is hereby replaced in its entirety by the following:
		
		  	“‘Market Disruption Event’ means, in respect of a Share, (i) a failure by the primary United States national or regional securities exchange or market on which the Shares are listed or admitted for trading to
open for trading during its regular trading session or (ii) the occurrence or existence prior to 1:00 p.m. (New York City time) on any Scheduled Valid Day for the Shares for more than one half-hour period in the aggregate during regular trading
hours of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in the Shares or in any options contracts or futures contracts relating to the
Shares.”
		
	 Settlement Terms.
	  	
		
	 Settlement Method:
	  	For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement
Method, but only if Counterparty shall have notified Dealer of the Relevant Settlement Method in the Notice of Exercise or Notice of Final Settlement Method, as applicable, for such Option.
		
	 Relevant Settlement Method:
	  	In respect of any Option:
		
		  	(i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(a)(iv)(A) of the Indenture (together with cash in lieu of
fractional Shares) (such settlement method, “Settlement in Shares”), (B) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Indenture with a Specified Cash Amount less than USD 1,000 or
(C) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share
Settlement;

  
 5 

			
		
		  	(ii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note in a combination of cash and Shares pursuant to Section [14.02(a)(iv)(C)] of the Indenture with a Specified Cash Amount
greater than USD 1,000, then the Relevant Settlement Method for such Option shall be Combination Settlement; and
		
		  	(iii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note entirely in cash pursuant to Section 14.02(a)(iv)(B) of the Indenture (such settlement method,
“Settlement in Cash”), then the Relevant Settlement Method for such Option shall be Cash Settlement.
		
	 Net Share Settlement:
	  	If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “Net Share
Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid
Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date in no
event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the Settlement Date for such Option.
		
		  	Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
		
	 Combination Settlement:
	  	If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:
		
		  	 (i) cash (the “Combination Settlement Cash Amount”) equal to the sum, for
each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and
(y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above
results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

		  	 (ii)  Shares (the “Combination Settlement Share Amount”) equal to the
sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid
Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period;
provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be
zero;

		
		  	provided that for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date in no event shall the sum of (x) the Combination Settlement Cash Amount for any
Option and (y) the Combination Settlement Share Amount for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.
		
		  	Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging
Period.
		
	 Cash Settlement:
	  	If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an
amount of cash (the “Cash Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid Day, divided by (ii) the number
of Valid Days in the Settlement Averaging Period.
		
	 Daily Option Value:
	  	For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) the Relevant Price on such Valid Day less the Strike Price on such Valid Day; provided that if the
calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.
		
	 Make-Whole Adjustment:
	  	Notwithstanding anything to the contrary herein, in respect of any exercise of Options relating to a conversion of Convertible Notes for which additional Shares will be added to the “Conversion Rate” (as defined in the
Indenture) as determined pursuant to Section [14.03] of the Indenture, the Daily Option Value shall be calculated as if the Option Entitlement included the Applicable Percentage of the

  
 7 

			
		
		  	number of such additional Shares as determined with reference to the adjustment set forth in such Section 14.03 of the Indenture; provided that if the sum of (i) the product of (a) the number of Shares (if any)
deliverable by Dealer to Counterparty per exercised Option and (b) the Applicable Limit Price on the Settlement Date and (ii) the amount of cash (if any) payable by Dealer to Counterparty per exercised Option would otherwise exceed the
amount per Option, as determined by the Calculation Agent, that would be payable by Dealer under Section 6 of the Agreement if (x) the relevant Conversion Date were an Early Termination Date resulting from an Additional Termination Event
with respect to which the Transaction was the sole Affected Transaction and Counterparty was the sole Affected Party and (y) Section 14.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the
extent necessary to eliminate such excess.
		
	 Applicable Limit:
	  	For any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder of the related Convertible Note upon
conversion of such Convertible Note and (B) the number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note multiplied by the Applicable Limit Price on the Settlement Date
for such Option, over (ii) USD 1,000.
		
	 Applicable Limit Price:
	  	On any day, the opening price as displayed under the heading “Op” on Bloomberg page OKTA <equity> (or any successor thereto).
		
	 Valid Day:
	  	A day on which (i) there is no Market Disruption Event and (ii) trading in the Shares generally occurs on the Exchange or, if the Shares are not then listed on the Exchange, on the principal other United States national or
regional securities exchange on which the Shares are then listed or, if the Shares are not then listed on a United States national or regional securities exchange, on the principal other market on which the Shares are then listed or admitted for
trading. If the Shares are not so listed or admitted for trading, “Valid Day” means a Business Day.
		
	 Scheduled Valid Day:
	  	A day that is scheduled to be a Valid Day on the principal United States national or regional securities exchange or market on which the Shares are listed or admitted for trading. If the Shares are not so listed or admitted for
trading, “Scheduled Valid Day” means a Business Day.
		
	 Business Day:
	  	Any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank of New York is authorized or required by law or executive order to close or be closed.
		
	 Relevant Price:
	  	On any Valid Day, the per Share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page OKTA <equity> AQR (or any successor thereto) in respect of the period from the

  
 8 

			
		
		  	scheduled opening time of the Exchange to the Scheduled Closing Time of the Exchange on such Valid Day (or if such volume-weighted average price is unavailable at such time or is manifestly incorrect, the market value of one Share
on such Valid Day, as determined by the Calculation Agent in good faith and in a commercially reasonable manner using, if practicable, a volume-weighted average method). The Relevant Price will be determined without regard to after-hours trading or
any other trading outside of the regular trading session trading hours.
		
	 Settlement Averaging Period:
	  	For any Option and regardless of the Settlement Method applicable to such Option:
		
		  	 (i) if the related Conversion Date occurs prior to the Free Convertibility Date, the 40
consecutive Valid Days commencing on, and including, the second Valid Day following such Conversion Date; or

		
		  	 (ii)  if the related Conversion Date occurs on or following the Free Convertibility
Date, the 40 consecutive Valid Days commencing on, and including, the 42nd Scheduled Valid Day immediately prior to the Expiration Date.

		
	 Settlement Date:
	  	For any Option, the third Business Day immediately following the final Valid Day of the Settlement Averaging Period for such Option.
		
	 Settlement Currency:
	  	USD
		
	 Other Applicable Provisions:
	  	To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9 and 9.11 of the Equity Definitions will be applicable, except that all references in such provisions to
“Physically-settled” shall be read as references to “Share Settled”. “Share Settled” in relation to any Option means that Net Share Settlement or Combination Settlement is applicable to that Option.
		
	 Representation and Agreement:
	  	Notwithstanding anything to the contrary in the Equity Definitions (including, but not limited to, Section 9.11 thereof), the parties acknowledge that (i) any Shares delivered to Counterparty shall be, upon delivery,
subject to restrictions and limitations arising from Counterparty’s status as issuer of the Shares under applicable securities laws, (ii) Dealer may deliver any Shares required to be delivered hereunder in certificated form in lieu of
delivery through the Clearance System and (iii) any Shares delivered to Counterparty may be “restricted securities” (as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”)). With
respect to any such certificated shares (as described in clause (ii) above, the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by deleting the remainder of the provision after the word
“encumbrance” in the fourth line thereof.

	3.	Additional Terms applicable to the Transaction. 

 Adjustments applicable to the
Transaction: 
  

			
		
	 Potential Adjustment Events:
	  	Notwithstanding Section 11.2(e) of the Equity Definitions, a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in any Dilution Adjustment Provision, that would result in an
adjustment under the Indenture to the “Conversion Rate” or the composition of a “unit of Reference Property” or to any “Last Reported Sale Price”, “Daily VWAP,” “Daily Conversion Value” or
“Daily Settlement Amount” (each as defined in the Indenture). For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be made to the terms of the Transaction, on account of
(x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in
each case, in lieu of an adjustment under the Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of the first paragraph of Section 14.04(c) of the Indenture or
the fourth sentence of Section 14.04(d) of the Indenture).
		
	 Method of Adjustment:
	  	Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any Potential Adjustment Event, the Calculation Agent shall make an adjustment corresponding to the adjustment made
under the Indenture to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction.
		
		  	Notwithstanding the foregoing and “Consequences of Merger Events / Tender Offers” below:
		
		  	 (i) if the Calculation Agent, acting in good faith and in a commercially reasonable manner,
disagrees with any adjustment to the Convertible Notes pursuant to the terms and provisions of the Indenture that is the basis of any calculation hereunder and that involves an exercise of discretion by Counterparty or its board of directors
(including, without limitation, pursuant to Section 14.05 of the Indenture, Section 14.07 of the Indenture or any supplemental indenture entered into thereunder or in connection with any proportional adjustment or the determination of the
fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will, acting in good faith and in a commercially reasonable manner, determine the adjustment to be made to any one or more of the Strike
Price, Number of Options, Option Entitlement and any other variable relevant to the

  
 10 

			
		
		  	 exercise, settlement or payment for the Transaction in a commercially reasonable manner; provided that,
notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment was made to any Convertible Note under the Indenture because the relevant “Holder” (as such term is defined in
the Indenture) was deemed to be a record owner of the underlying Shares on the related Conversion Date, then the Calculation Agent shall make an adjustment, as determined by it, to the terms hereof in order to account for such Potential Adjustment
Event;

		
		  	 (ii)  in connection with any Potential Adjustment Event as a result of an event or
condition set forth in Section 14.04(b) of the Indenture or Section 14.04(c) of the Indenture where, in either case, the period for determining “Y” (as such term is used in Section 14.04(b) of the Indenture) or
“SP0” (as such term is used in Section 14.04(c) of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such Potential Adjustment Event, then the Calculation Agent
shall have the right, acting in good faith and in a commercially reasonable manner, to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to,
hedging mismatches and market losses) and expenses incurred by Dealer in connection with its commercially reasonable hedging activities as a result of such event or condition not having been publicly announced prior to the beginning of such period;
and

		
		  	 (iii)  if any Potential Adjustment Event is declared and (a) the event or
condition giving rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned, (b) the “Conversion Rate” (as defined in the Indenture) is otherwise not adjusted at the time or in the manner
contemplated by the relevant Dilution Adjustment Provision based on such declaration or (c) the “Conversion Rate” (as defined in the Indenture) is adjusted as a result of such Potential Adjustment Event and subsequently re-adjusted (each of clauses (a), (b) and (c), a “Potential Adjustment Event Change”) then, in each case, the Calculation Agent shall have the right, acting in good faith and in a commercially
reasonable manner, to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market

  
 11 

			
		
		  	 losses) and expenses incurred by Dealer in connection with its commercially reasonable hedging activities as a result
of such Potential Adjustment Event Change.

		
	 Dilution Adjustment Provisions:

	 Tender Offers:
	  	Applicable; provided that notwithstanding Section 12.1(d) of the Equity Definitions, a “Tender Offer” means the occurrence of any event or condition set forth in Section 14.04(e) of the
Indenture.
		
	 Consequences of Merger Events /

Tender Offers:
	  	 Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions, upon the occurrence of a Merger Event or a Tender Offer,
the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture to any one or more of the nature of the Shares (in the case of a Merger Event), Strike Price, Number of Options, Option Entitlement and any
other variable relevant to the exercise, settlement or payment for the Transaction (as determined by the Calculation Agent, acting in good faith and in a commercially reasonable manner, by reference to the relevant provisions of the Indenture),
subject to the second paragraph under “Method of Adjustment”; provided, however, that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to any Excluded Provision; provided further
that if, with respect to a Merger Event or a Tender Offer, (i) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation or is not organized under
the laws of the United States, any State thereof or the District of Columbia or (ii) the Counterparty to the Transaction following such Merger Event or Tender Offer will not be a corporation organized under the laws of the United States, any
State thereof or the District of Columbia, then, in either case, Cancellation and Payment (Calculation Agent Determination) may apply at Dealer’s sole election.

		
	 Nationalization, Insolvency

or Delisting:
	  	 Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii)

re-quoted on any of The New York Stock Exchange, The

		  	NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors), such exchange or quotation system shall thereafter be deemed to be the
Exchange.

the avoidance of doubt and without limitation, adoption, effectiveness or promulgation of new regulations authorized or mandated by existing statute)” at the end of clause (A) thereof.

		  	 “For the avoidance of doubt, the term “equity price risk” shall be deemed to include, but shall not be
limited to, stock price and volatility risk. And, for the further avoidance of doubt, any such transactions or assets referred to in phrases (A) or (B) above must be available on commercially reasonable pricing terms.”; and

	8.	Representations and Warranties of Counterparty. 

 Each of the representations and
warranties of Counterparty set forth in Section 1 of the Purchase Agreement (the “Purchase Agreement”) dated as of [DATE], 2018, among Counterparty and
[                ] and [                ], as representatives of the initial purchasers
party thereto (the “Initial Purchasers”), are true and correct and are hereby deemed to be repeated to Dealer as if set 

  
 15 

 
forth herein. Counterparty hereby further represents and warrants to Dealer on the date hereof and on and as of the Premium Payment Date that: 

 

	 	(a)	Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all
necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its
terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity,
including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by
federal or state securities laws or public policy relating thereto. 

  

	 	(b)	Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Counterparty hereunder will conflict with or result in a breach of the certificate of incorporation or by-laws (or any equivalent documents) of Counterparty, or any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or any agreement or instrument
filed as an exhibit to Counterparty’s (i) Registration Statement on Form S-1, as filed with the Securities and Exchange Commission (“SEC”) on April 5, 2017, (ii) Quarterly
Report on Form 10-Q, filed with the SEC on September 8, 2017, and (iii) Current Report on Form 8-K, filed with the SEC on December 6, 2017, to which
Counterparty or any of its subsidiaries is a party or by which Counterparty or any of its subsidiaries is bound or to which Counterparty or any of its subsidiaries is subject, or constitute a default under, or result in the creation of any lien
under, any such agreement or instrument. 

  

	 	(c)	To Counterparty’s knowledge, no consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by
Counterparty of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act or state securities laws. 

  

	 	(d)	Counterparty is not and, after consummation of the transactions contemplated hereby, will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940,
as amended. 

  

	 	(e)	Counterparty is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended, other than a person that is an eligible contract participant under
Section 1a(18)(C) of the Commodity Exchange Act). 

  

	 	(f)	Counterparty is not, on the date hereof, aware of any material non-public information with respect to Counterparty or the Shares. 

 

	 	(g)	Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise
independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least USD 50 million. 

 

	 	(h)	 Counterparty acknowledges that the board of directors of Counterparty has granted the approval necessary to cause
the restrictions set forth in Section 203 of the Delaware General Corporation Law (the “Business Combinations Statute”) to be inapplicable to the Transaction, including, without limitation, transactions in, or linked to,
Counterparty’s securities to be effected by Dealer in connection with hedging the Transaction, and as a result neither Dealer nor any of its affiliates or associates shall be subject to the restrictions in the Business Combinations Statute as
an “interested stockholder” of Counterparty by virtue of (i) its entry into the Transaction or (ii) any act that Dealer may take in furtherance of the Transaction (including without limitation the

  
 16 

	 	
hedging transactions to be effected by Dealer or its affiliates in connection with the Transaction, whether in Shares or transactions that references the Shares) or (iii) its purchase of, as
the case may be, and/or market-making in, the Convertible Notes. 

  

	 	(i)	On each of the Trade Date and the Premium Payment Date, Counterparty is not “insolvent” (as such term is defined under Section 101(32) of the U.S. Bankruptcy Code (Title 11 of the United States Code) (the
“Bankruptcy Code”)) and Counterparty would be able to purchase the Number of Shares in compliance with the laws of the jurisdiction of Counterparty’s incorporation. 

 

	9.	Other Provisions. 

  

	 	(a)	Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to the matters set forth in Sections 8(a) through (c) of this Confirmation; provided
that any such opinion of counsel may contain customary exceptions and qualifications, including, without limitation, exceptions and qualifications relating to indemnification provisions. Delivery of such opinion to Dealer shall be a condition
precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement. 

  

	 	(b)	Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”)
on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than [     ]12 million (in the case of the first such
notice) or (ii) thereafter more than [    ]13 million less than the number of Shares included in the immediately preceding Repurchase Notice. Counterparty agrees to
indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses
(including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of
hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become
subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for
any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental
or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified
Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty
may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its
written consent, but if settled with such consent or if there be a final judgment for the plaintiff, 

  

	12 	Insert the number of Shares outstanding that would cause Dealer’s current position in the Shares underlying the Transaction (including the number of Shares underlying any additional transaction if the greenshoe is
exercised in full, and any Shares under pre-existing call option transactions with Counterparty) to increase by 0.5%. 

	13 	 Insert the number of Shares that, if repurchased, would cause Dealer’s current position in the Shares
underlying the Transaction (including the number of Shares underlying any additional transaction if the greenshoe is exercised in full, and any Shares under pre-existing call option transactions with
Counterparty) to increase by a further 0.5% from the threshold for the first Repurchase Notice.

Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent
of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder
by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person.
If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not
limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the
termination of the Transaction. 

  

	 	(c)	Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), of any securities of Counterparty, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Counterparty shall not, until the second Scheduled Trading Day
immediately following the Effective Date, engage in any such distribution. 

  

	 	(d)	No Manipulation. Counterparty is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise
or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act. 

 

	 	(e)	Transfer or Assignment. 

  

	 	(i)	Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”);
provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to the following conditions: 

 

	 	(A)	With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 9(b) or any obligations under Section 9(m) or 9(r) of this
Confirmation; 

  

	 	(B)	Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended); 

 

	 	(C)	Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws
in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by
such third party and Counterparty, as are requested and reasonably satisfactory to Dealer; 

  

	 	(D)	Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have
been required to pay to Counterparty in the absence of such transfer and assignment; 

  
 18 

	 	(E)	An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment; 

  

	 	(F)	Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit
Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and 

  

	 	(G)	Counterparty shall be responsible for all commercially reasonable out-of-pocket costs and expenses, including commercially reasonable
counsel fees, incurred by Dealer in connection with such transfer or assignment. 

  

	 	(ii)	 Dealer may not transfer or assign all or any part of its rights or obligations under the Transaction without
Counterparty’s consent other than to an affiliate of Dealer (1) that has a long-term issuer rating at the time of such transfer or assignment that is equal to or better than Dealer’s credit rating at the time of such transfer or
assignment, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions, by Dealer or its ultimate parent; provided that, at the time
of such transfer or assignment either (i) the transferee in any such transfer or assignment is a “dealer in securities” within the meaning of Section 475(c)(1) of the Code or (ii) the transfer or assignment does not result
in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code. Without limiting the foregoing, no transfer or assignment by Dealer shall be permitted hereunder that would result in the occurrence of an Event of Default,
Potential Event of Default or Termination Event. If at any time at which (A) the Section 16 Percentage exceeds 8.5%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any
applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer, acting in good faith, is unable after using its commercially reasonable efforts to effect a transfer or assignment of
Options to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early
Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists. Dealer shall notify Counterparty of an Excess Ownership
Position with respect to which it intends to seek a transfer or assignment as soon as reasonably practicable after becoming aware of such Excess Ownership Position. In the event that Dealer so designates an Early Termination Date with respect to a
portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of
Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for
the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “Section 16
Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation with Dealer for purposes of the
“beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the
meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a
higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the
numerator of which is the 

  
 19 

	 	
sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to
Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of
Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares
(“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its
reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations (other than any Form 13F, Schedule 13D or
Schedule 13G filing under the Exchange Act) or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as
determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding. 

  

	 	(iii)	Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or
from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the
Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty only to the extent of any such performance. 

 

	 	(f)	Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s commercially reasonable hedging activities
hereunder, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice
to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) as follows: 

 

	 	(i)	in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th)
Exchange Business Day following such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date; 

  

	 	(ii)	the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal
Settlement Date; and 

  

	 	(iii)	if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case
may be, will apply on each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause
(i) above. 

  

	 	(g)	Role of Agent. [Insert Any Dealer Agency Language, If Applicable] 

  

	 	(h)	Additional Termination Events. 

  

	 	(i)	 Notwithstanding anything to the contrary in this Confirmation, if an event of default with respect to
Counterparty occurs that results in an acceleration of the Convertible Notes under 

  
 20 

	 	
the terms of the Convertible Notes as set forth in Section 6.01 of the Indenture, then such event of default shall constitute an Additional Termination Event applicable to the Transaction
and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate
an Early Termination Date pursuant to Section 6(b) of the Agreement. 

  

	 	(ii)	Promptly (but in any event within five Scheduled Trading Days) following any Repurchase Event (as defined below), Counterparty may notify Dealer of such Repurchase Event and the aggregate principal amount of Convertible
Notes subject to such Repurchase Event (any such notice, a “Convertible Notes Repurchase Notice”); provided that any such Convertible Notes Repurchase Notice shall contain an acknowledgment by Counterparty of its
responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act and the rules and regulations thereunder, in respect of such Repurchase Event and the delivery of such Convertible Notes
Repurchase Notice. The receipt by Dealer from Counterparty of any Convertible Notes Repurchase Notice shall constitute an Additional Termination Event as provided in this Section 9(h)(ii). Upon receipt of any such Convertible Notes Repurchase
Notice, Dealer shall designate an Exchange Business Day following receipt of such Convertible Notes Repurchase Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related settlement date for the
relevant Repurchase Event) as an Early Termination Date with respect to the portion of the Transaction corresponding to a number of Options (the “Repurchase Options”) equal the lesser of (A) (x) the aggregate principal amount
of such Convertible Notes specified in such Convertible Notes Repurchase Notice, divided by USD 1,000 [minus the number of “Repurchase Options” (as defined in the Base Call Option Confirmation), if any, that relate to such
Convertible Notes], and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Repurchase Options. Any payment hereunder with respect
to such termination (the “Repurchase Unwind Payment”) shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to
the Transaction and a Number of Options equal to the number of Repurchase Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were the
sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this Section 9(h)(ii) as if Counterparty was not the Affected
Party). “Repurchase Event” means that (i) any Convertible Notes are repurchased (whether pursuant to Section 15.02 of the Indenture or otherwise) by Counterparty or any of its subsidiaries, (ii) any Convertible Notes
are delivered to Counterparty in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (iii) any principal of any of the Convertible Notes is repaid prior to the final maturity date of the
Convertible Notes (other than upon acceleration of the Convertible Notes described in Section 9(h)(i)), or (iv) any Convertible Notes are exchanged by or for the benefit of the Holders (as defined in the Indenture) thereof for any other
securities of Counterparty or any of its Affiliates (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction; provided that any conversion of Convertible Notes that occurs pursuant to the terms
of the Indenture shall not constitute a Repurchase Event. For the avoidance of doubt, in determining the amount payable in respect of such Affected Transaction pursuant to Section 6 of the Agreement, the Calculation Agent shall assume
(1) the relevant Repurchase Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (2) no adjustments to the Conversion Rate have occurred
pursuant to any Excluded Provision and (3) the corresponding Convertible Notes remain outstanding as if the circumstances related to the Repurchase Event had not occurred. 

  
 21 

	 	(iii)	Notwithstanding anything to the contrary in this Confirmation, the occurrence of an Amendment Event shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional
Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant
to Section 6(b) of the Agreement. “Amendment Event” means that Counterparty amends, modifies, supplements, waives or obtains a waiver in respect of any term of the Indenture or the Convertible Notes governing the principal
amount, coupon, maturity, repurchase obligation of Counterparty, any term relating to conversion of the Convertible Notes (including changes to the conversion rate, conversion rate adjustment provisions, conversion settlement dates or conversion
conditions), or any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes to amend (other than, in each case, any amendment or supplement (x) pursuant to Section 10.01(n) of
the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum or (y) pursuant to Section 14.07 of the Indenture), in each case, without the consent of
Dealer. 

  

	 	(i)	Amendments to Equity Definitions. 

  

	 	(i)	Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and
(2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master
Agreement with respect to that Issuer.” 

  

	 	(ii)	Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party”
with “notice to Counterparty” in the first sentence of such section. 

  

	 	(iii)	Section 12.9(b)(vi) of the Equity Definitions is hereby amended by (1) adding the word “or” immediately before subsection “(B)”, (2) deleting the comma at the end of subsection (A), (3)
deleting subsection (C) in its entirety, (4) deleting the word “or” immediately preceding subsection (C) and (5) replacing the words “either party” in the last sentence of such Section with “Dealer”.

  

	 	(j)	Setoff. Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any
other agreement, applicable law or otherwise. 

  

	 	(k)	 Alternative Calculations and Payment on Early Termination and on Certain Extraordinary
Events. If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon
the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that
is within Counterparty’s control, or (iii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party other than an Event of Default of the type described in
Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and
if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer
shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m.
(New York City time) on the Merger Date, Tender Offer Date, Announcement 

  
 22 

	 	
Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not
apply, (b) Counterparty remakes the representation set forth in Section 8(f) as of the date of such election and (c) Dealer agrees, in its sole discretion, to such election, in which case the provisions of Section 12.7 or
Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply. 

  

			
	 Share Termination Alternative:
	  	If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due
pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable, in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of
payment.
		
	 Share Termination Delivery Property:
	  	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery
Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.
		
	 Share Termination Unit Price:
	  	The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the
time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the
commercially reasonable purchase of Share Termination Delivery Property.
		
	 Share Termination Delivery Unit:
	  	One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the
“Exchange Property”), a unit consisting of the type and amount of such Exchange Property received by holders of all or substantially all Shares determined on a per share basis (without consideration of any requirement to pay cash or
other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.
		
	 Failure to Deliver:
	  	Applicable
		
	 Other applicable provisions:
	  	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set

  
 23 

			
		  	forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share
Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination
Alternative is applicable to the Transaction.

  

	 	(l)	Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the
Transaction. Each party (i) certifies that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the
foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein. 

 

	 	(m)	Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer based on the advice of counsel, the Shares acquired by Dealer for the purpose of effecting a commercially
reasonable hedge of its obligations pursuant to the Transaction (other than any such Shares that were, at the time of acquisition by Dealer, “restricted securities” (as defined in Rule 144(a)(3) under the Securities Act)) (the
“Hedge Shares”) cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered
offering, make available to Dealer an effective registration statement under the Securities Act and (A) enter into an agreement, in form and substance satisfactory to Dealer, substantially in the form of an underwriting agreement for a
registered secondary offering of comparable size for an issuer comparable to Counterparty, (B) provide accountant’s “comfort” letters in customary form for a registered secondary offering of comparable size for an issuer
comparable to Counterparty, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Dealer, (D) provide other customary opinions, certificates and closing documents customary in
form for a registered secondary offering of comparable size for an issuer comparable to Counterparty and (E) afford Dealer a reasonable opportunity to conduct a “due diligence” investigation with respect to Counterparty customary in
scope for a registered secondary offering of comparable size for an issuer comparable to Counterparty; provided, however, that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the
results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above (after Dealer has given Counterparty reasonable notice of its determination and provided Counterparty with reasonable
opportunity to satisfy Dealer’s concerns), then clause (ii) or clause (iii) of this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into
a private placement agreement and use best efforts to include therein representations and other provisions, customary for private placements of equity securities of comparable size for an issuer comparable to Counterparty, in form and substance
commercially reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its commercially reasonable judgment, to compensate Dealer for any discount from
the public market price of the Shares incurred on the sale of Hedge Shares in a private placement), or (iii) purchase the Hedge Shares from Dealer at the Relevant Price on such Exchange Business Days, and in the amounts, requested by Dealer.
For the avoidance of doubt, under no circumstances shall Counterparty be obligated to make the election described in clause (iii) of the preceding sentence. 

  

	 	(n)	Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all
persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax
structure. 

  
 24 

	 	(o)	Right to Extend. Dealer may postpone or add, in whole or in part, any Valid Day or Valid Days during the Settlement Averaging Period or any other date of valuation, payment or delivery by Dealer, with
respect to some or all of the Options hereunder, if Dealer reasonably determines (in its commercially reasonable discretion with respect to clause (i) below and upon the advice of counsel with respect to clause (ii) below) that such action
is reasonably necessary or appropriate to (i) preserve Dealer’s commercially reasonable hedging or commercially reasonable hedge unwind activity hereunder in light of existing liquidity conditions (but only in the case of a material
decrease in liquidity relative to Dealer’s expectations as of the Trade Date), or (ii) enable Dealer to effect transactions in Shares in connection with its commercially reasonable hedging, commercially reasonable hedge unwind or
settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures
applicable to Dealer (so long as such policies and procedures would generally be applicable to counterparties similar to Counterparty and transactions similar to the Transaction); provided that no such Valid Day or other date of valuation,
payment or delivery may be postponed or added more than 40 Valid Days after the original Valid Day or other date of valuation, payment or delivery, as the case may be. 

 

	 	(p)	Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are senior to the
claims of common stockholders of Counterparty in any United States bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by
Counterparty of its obligations and agreements with respect to the Transaction; provided further that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction. For
the avoidance of doubt, notwithstanding any provision of this Confirmation, the Agreement, the Equity Definitions, or any other agreement between the parties to the contrary, the obligations of Counterparty under the Transaction are not secured by
any collateral. 

  

	 	(q)	Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code, and
the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party’s right to liquidate the Transaction and to exercise
any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as described in the Bankruptcy Code, and (iii) each payment and delivery of cash,
securities or other property hereunder to constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code. 

 

	 	(r)	Notice of Certain Other Events. Counterparty covenants and agrees that: 

  

	 	(i)	promptly following the public announcement of the results of any election by the holders of Shares with respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written
notice of (x) the weighted average of the types and amounts of consideration that holders of Shares have elected to receive upon consummation of such Merger Event or (y) if no holders of Shares affirmatively make such election, the types
and amounts of consideration actually received by holders of Shares (the date of such notification, the “Consideration Notification Date”); provided that in no event shall the Consideration Notification Date be later than the
date on which such Merger Event is consummated; and 

  

	 	(ii)	(A) Counterparty shall give Dealer commercially reasonable advance (but in no event less than one Exchange Business Day) written notice of the section or sections of the Indenture and, if applicable, the formula
therein, pursuant to which any adjustment will be made to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer and (B) promptly following any such adjustment, Counterparty shall give Dealer
written notice of the details of such adjustment. 

  
 25 

	 	(s)	Wall Street Transparency and Accountability Act. In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), the parties hereby agree that
neither the enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend
or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or
the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as defined in the Agreement)). 

 

	 	(t)	Agreements and Acknowledgements Regarding Hedging. Counterparty understands, acknowledges and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or
sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be
active in the market for Shares other than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in securities of
Issuer shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Relevant Prices; and (D) any market activities of Dealer and its affiliates with respect to Shares may affect
the market price and volatility of Shares, as well as the Relevant Prices, each in a manner that may be adverse to Counterparty. 

  

	 	(u)	Early Unwind. In the event that the sale of the “Firm Securities” (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers for any reason, or
Counterparty fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment
Date or such later date, the “Early Unwind Date”), the Transaction shall automatically terminate (the “Early Unwind”) on the Early Unwind Date and (x) the Transaction and all of the respective rights and
obligations of Dealer and Counterparty under the Transaction shall be cancelled and terminated and (y) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party with respect to
any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date. Each of Dealer and Counterparty represents and acknowledges to the other that,
upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged. 

  

	 	(v)	Payment by Counterparty. In the event that, following payment of the Premium, (i) an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event
or an Event of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated under Section 6(e) of the Agreement, or
(ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero. 

 

	 	(w)	Conduct Rules. Each party acknowledges and agrees to be bound by the Conduct Rules of the Financial Industry Regulatory Authority, Inc. applicable to transactions in options, and further agrees not to
violate the position and exercise limits set forth therein, in all case as such rules are applicable to such party. 

  
 26 

	 	(x)	Adjustments. For the avoidance of doubt, whenever the Calculation Agent or the Determining Party is called upon to make an adjustment or determine an amount pursuant to the terms of this Confirmation or
the Equity Definitions to take into account the effect of an event, the Calculation Agent or the Determining Party, as the case may be, shall make such adjustment or determine such amount, as the case may be, by reference to the effect of such event
on the Hedging Party, assuming that the Hedging Party maintains a commercially reasonable hedge position. 

  

	 	(y)	Amendment. This Confirmation and the Agreement may not be modified, amended or supplemented, except in a written instrument signed by Counterparty and Dealer. 

 

	 	(z)	Counterparts. This Confirmation may be executed in several counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. 

 

	 	(aa)	Payee Tax Representations. For the purpose of Section 3(f) of the Agreement, Counterparty makes the representations below: 

 

	 	(i)	Counterparty is a corporation created or organized in the United States or under the laws of the United States and its U.S. taxpayer identification number is [        ]. It
is “exempt” within the meaning of Treasury Regulation sections 1.6041-3(p) and 1.6049- 4(c) from information reporting on IRS Form 1099 and backup withholding. 

 

	 	(bb)	[Tax Forms. For the purpose of Section 4(a)(i) of the Agreement, Counterparty shall provide to Dealer a valid U.S. Internal Revenue Service Form W-9, or any
