2014 Stock Option Plan 

STOCK OPTION AGREEMENT 

This STOCK OPTION AGREEMENT (“Agreement”), dated
as of the _______________ day of _______________ ,
201        is made by and between
ENERTOPIA CORPORATION, a Nevada corporation (the “Corporation”),
and ______________________________(the “Optionee,” which term as used
herein shall be deemed to include any successor to the Optionee by will or by
the laws of descent and distribution, unless the context shall otherwise
require). 

BACKGROUND 

Pursuant to the Corporation’s 2014 Stock Option Plan (the
“Plan”), the Corporation, acting through the Committee of the Board of
Directors (if a committee has been formed to administer the Plan) or its entire
Board of Directors (if no such committee has been formed) responsible for
administering the Plan (in either case, referred to herein as the
“Committee”), approved the issuance to the Optionee,
______________________ share options at $ __________ per share,
effective as of the date set forth above, of a stock option to purchase shares
of Common Stock of the Corporation at the price (the “Option Price”) set
forth in the attached Notice of Grant (which is expressly incorporated herein
and made a part hereof, the “Notice of Grant”), upon the terms and
conditions hereinafter set forth. 

NOW, THEREFORE, in consideration of the mutual premises
and undertakings hereinafter set forth, the parties hereto agree as follows:

1.     Option; Option Price.
On behalf of the Corporation, the Committee hereby grants to the Optionee the
option (the “Option”) to purchase, subject to the terms and conditions of
this Agreement and the Plan (which is incorporated by reference herein and which
in all cases shall control in the event of any conflict with the terms,
definitions and provisions of this Agreement), that number of shares of Common
Stock of the Corporation set forth in the Notice of Grant, at an exercise price
per share equal to the Option Price as is set forth in the Notice of Grant (the
“Optioned Shares”). If designated in the Notice of Grant as an “incentive
stock option,” the Option is intended to qualify for Federal income tax purposes
as an “incentive stock option” within the meaning of Section 422 of the Code. A
copy of the Plan as in effect on the date hereof has been supplied to the
Optionee, and the Optionee hereby acknowledges receipt thereof. 

2.     Term. The term
(the “Option Term”) of the Option shall commence on the date of this
Agreement and shall expire on the Expiration Date set forth in the Notice of
Grant unless such Option shall theretofore have been terminated in accordance
with the terms of the Notice of Grant, this Agreement or of the Plan. 

1 

3.     Time of Exercise.

(a)     Unless accelerated in the
discretion of the Committee or as otherwise provided herein, the Option shall
become exercisable during its term in accordance with the Vesting Schedule set
out in the Notice of Grant. Subject to the provisions of Sections 5 and 8
hereof, shares as to which the Option becomes exercisable pursuant to the
foregoing provisions may be purchased at any time thereafter prior to the
expiration or termination of the Option. 

(b)     Anything contained in this
Agreement to the contrary notwithstanding, to the extent the Option is intended
to be an Incentive Stock Option, the Option shall not be exercisable as an
Incentive Stock Option, and shall be treated as a Non-Statutory Option, to the
extent that the aggregate Fair Market Value on the date hereof of all stock with
respect to which Incentive Stock Options are exercisable for the first time by
the Optionee during any calendar year (under the Plan and all other plans of the
Corporation, its parent and its subsidiaries, if any) exceeds $100,000. 

4.     Termination of Option.

(a)     The Optionee may exercise the
Option (but only to the extent the Option was exercisable at the time of
termination of the Optionee’s Business Relationship with the Corporation, its
parent or any of its subsidiaries) at any time within three (3) months following
the termination of the Optionee’s Business Relationship with the Corporation,
its parent or any of its subsidiaries, but not later than the scheduled
expiration date. If the termination of the Optionee’s employment is for cause or
is otherwise attributable to a breach by the Optionee of an employment,
non-competition, non-disclosure or other material agreement, the Option shall
expire immediately upon such termination. If the Optionee is a natural person
who dies while in a Business Relationship with the Corporation, its parent or
any of its subsidiaries, this option may be exercised, to the extent of the
number of shares with respect to which the Optionee could have exercised it on
the date of his death, by his estate, personal representative or beneficiary to
whom this option has been assigned pursuant to Section 9 of the Plan, at any
time within the twelve (12) month period following the date of death. If the
Optionee is a natural person whose Business Relationship with the Corporation,
its parent or any of its subsidiaries is terminated by reason of his disability,
this Option may be exercised, to the extent of the number of shares with respect
to which the Optionee could have exercised it on the date the Business
Relationship was terminated, at any time within the twelve (12) month period
following the date of such termination, but not later than the scheduled
expiration date. At the expiration of such three (3) or twelve (12) month period
or the scheduled expiration date, whichever is the earlier, this Option shall
terminate and the only rights hereunder shall be those as to which the Option
was properly exercised before such termination. 

(b)     Anything contained herein to the
contrary notwithstanding, the Option shall not be affected by any change of
duties or position of the Optionee (including a transfer to or from the
Corporation, its parent or any of its subsidiaries) so long as the Optionee
continues in a Business Relationship with the Corporation, its parent or any of
its subsidiaries. 

2 

5.     Procedure for
Exercise. 

(a)     The
Option may be exercised, from time to time, in whole or in part (but for the
purchase of whole shares only), by delivery of a written notice in the form
attached as Exhibit A hereto (the “Notice”) from the Optionee to
the Secretary of the Corporation, which Notice shall: 

(a)     state that the Optionee elects to
exercise the Option; 

(b)     state the number of shares with
respect to which the Option is being exercised (the “Optioned Shares”);

(c)     state the method of payment for the
Optioned Shares pursuant to Section 5(b); 

(d)     state the date upon which the
Optionee desires to consummate the purchase of the Optioned Shares (which date
must be prior to the termination of such Option and no later than 30 days from
the delivery of such Notice); 

(e)     include any representations of the
Optionee required under Section 8(b); 

(f)     if the Option shall be exercised in
accordance with Section 9 of the Plan by any person other than the Optionee,
include evidence to the satisfaction of the Committee of the right of such
person to exercise the Option; and 

(b)     Payment of the Option Price for the
Optioned Shares shall be made either (i) by delivery of cash or a check to the
order of the Corporation in an amount equal to the Option Price, (ii) if
approved by the Committee, by delivery to the Corporation of shares of Common
Stock of the Corporation having a Fair Market Value on the date of exercise
equal in amount to the Option Price of the options being exercised, (iii) by any
other means which the Board of Directors determines are consistent with the
purpose of the Plan and with applicable laws and regulations (including, without
limitation, the provisions of Rule 16b-3 and Regulation T promulgated by the
Federal Reserve Board), or (iv) by any combination of such methods of
payment.

(c)     The Corporation shall issue a stock
certificate in the name of the Optionee (or such other person exercising the
Option in accordance with the provisions of Section 9 of the Plan) for the
Optioned Shares as soon as practicable after receipt of the Notice and payment
of the aggregate Option Price for such shares. 

6.     No Rights as a
Stockholder. The Optionee shall not have any privileges of a
stockholder of the Corporation with respect to any Optioned Shares until the
date of issuance of a stock certificate pursuant to Section 5(c). 

7.    
Adjustments. The Plan contains provisions covering
the treatment of options in a number of contingencies such as stock splits and
mergers. Provisions in the Plan for adjustment with respect to stock subject to
options and the related provisions with respect to successors to the business of
the Corporation are hereby made applicable hereunder and are incorporated herein by reference. In general, the Optionee should not assume
that options would survive the acquisition of the Corporation. 

3 

8.     Additional Provisions Related
to Exercise.

(a)     The Option shall be exercisable
only on such date or dates and during such period and for such number of shares
of Common Stock as are set forth in this Agreement. 

(b)     To exercise the Option, the
Optionee shall follow the procedures set forth in Section 5 hereof. Upon the
exercise of the Option at a time when there is not in effect a registration
statement under the Securities Act of 1933, as amended (the “Securities
Act”), relating to the shares of Common Stock issuable upon exercise of the
Option, the Committee in its discretion may, as a condition to the exercise of
the Option, require the Optionee (i) to execute an Investment Representation
Statement substantially in the form set forth in Exhibit B hereto and
(ii) to make such other representations and warranties as are deemed appropriate
by counsel to the Corporation.

(c)     Stock certificates representing
shares of Common Stock acquired upon the exercise of Options that have not been
registered under the Securities Act shall, if required by the Committee, bear an
appropriate restrictive legend referring to the Securities Act. No shares of
Common Stock shall be issued and delivered upon the exercise of the Option
unless and until the Corporation and/or the Optionee shall have complied with
all applicable Federal or state registration, listing and/or qualification
requirements and all other requirements of law or of any regulatory agencies
having jurisdiction. 

(d)     Subject to the provisions of this
Agreement and the Plan and subject to compliance with any applicable securities
laws and the policies of the Canadian Securities Exchange, the Options shall be
exercisable, in full or in part, at any time after vesting, until termination,
provided that if the Optionee is subject to the reporting and liability
provisions of Section 16 of the Securities Exchange Act of 1934,
as amended, the Optionee shall be precluded from selling, transferring or
otherwise disposing of any Optioned Shares during the six months immediately
following the grant of the Options unless an exemption is available to such
restrictions. If less than all of the Optioned Shares included in the vested
portion of any Options are purchased, the remainder may be purchased at any
subsequent time prior to the Expiry Date. Only whole Optioned Shares may be
issued pursuant to the exercise of any Options, and to the extent that any
Option covers less than one Optioned Share, it is not exercisable. 

9.     No Evidence of Employment or
Service. Nothing contained in the Plan or this Agreement shall
confer upon the Optionee any right to continue in a Business Relationship with
the Corporation, its parent or any of its subsidiaries or interfere in any way
with the right of the Corporation, its parent or its subsidiaries (subject to
the terms of any separate agreement to the contrary) to terminate the Optionee’s
Business Relationship or to increase or decrease the Optionee’s compensation at
any time. 

10.    Restriction on
Transfer. The Option may not be transferred, pledged, assigned,
hypothecated or otherwise disposed of in any way by the Optionee, except by will
or by the laws of descent and distribution, and may be exercised during the
lifetime of the Optionee only by the Optionee. If the Optionee dies, the Option shall thereafter be
exercisable, during the period specified in Section 4, by his executors or
administrators to the full extent to which the Option was exercisable by the
Optionee at the time of his death. The Option shall not be subject to execution,
attachment or similar process. Any attempted assignment, transfer, pledge,
hypothecation or other disposition of the Option contrary to the provisions
hereof, and the levy of any execution, attachment or similar process upon the
Option, shall be null and void and without effect. The words “transfer” and
“dispose” include without limitation the making of any sale, exchange,
assignment, gift, security interest, pledge or other encumbrance, or any
contract therefor, any voting trust or other agreement or arrangement with
respect to the transfer of any interest, beneficial or otherwise, in the Option,
the creation of any other claim thereto or any other transfer or disposition
whatsoever, whether voluntary or involuntary, affecting the right, title,
interest or possession with respect to the Option. 

4 

11.     Specific
  Performance. Optionee expressly agrees that the Corporation will be
  irreparably damaged if the provisions of this Agreement and the Plan are not
  specifically enforced. Upon a breach or threatened breach of the terms,
  covenants and/or conditions of this Agreement or the Plan by the Optionee, the
  Corporation shall, in addition to all other remedies, be entitled to a temporary
  or permanent injunction, without showing any actual damage, and/or decree for
  specific performance, in accordance with the provisions hereof and thereof. The
  Board of Directors shall have the power to determine what constitutes a breach
  or threatened breach of this Agreement or the Plan. Any such determinations
shall be final and conclusive and binding upon the Optionee. 

12.     Disqualifying
Dispositions. To the extent the Option is intended to be an Incentive
Stock Option, and if the Optioned Shares are disposed of within two years
following the date of this Agreement or one year following the issuance thereof
to the Optionee (a “Disqualifying Disposition”), the Optionee shall,
immediately prior to such Disqualifying Disposition, notify the Corporation in
writing of the date and terms of such Disqualifying Disposition and provide such
other information regarding the Disqualifying Disposition as the Corporation may
reasonably require. 

13.     Notices. All
notices or other communications which are required or permitted hereunder shall
be in writing and sufficient if (i) personally delivered or sent by telecopy,
(ii) sent by nationally-recognized overnight courier or (iii) sent by registered
or certified mail, postage prepaid, return receipt requested, addressed as

given may have furnished to the other party in writing in accordance herewith.
Any such communication shall be deemed to have been given (i) when delivered, if
personally delivered, or when telecopied, if telecopied, (ii) on the first
Business Day (as hereinafter defined) after dispatch, if sent by
nationally-recognized overnight courier and (iii) on the third Business Day
following the date on which the piece of mail containing such communication is posted, if sent by mail. As used herein,

5 

14.    Representations and Warranties.
  The Optionee hereby represents and warrants to and covenants with the
  Corporation (which representations, warranties and covenants shall survive the
closing) that: 

	 	(a) 	
      the Optionee is a director, officer, employee or
      consultant of the Corporation or subsidiary of the Corporation;

	 	 	 
	 	(b) 	
      if the Optionee is a consultant and resident in Canada,

      related entity of the Corporation, other than services provided in
      relation to a distribution,

	 	 	 
	 	2) 	
      provides the services under a written contract with the
      Corporation or a related entity of the issuer, and

	 	 	 
	 	3) 	
      spends or will spend a significant amount of time and
      attention on the affairs and business of the issuer or a related entity of
      the issuer;

	 	(c) 	
      if an employee or consultant of the Corporation or
      subsidiary of the Corporation, the Optionee is a bona fide employee or
      consultant of the Corporation or subsidiary of the
  Corporation;

14.    No Waiver. No waiver
of any breach or condition of this Agreement shall be deemed to be a waiver of
any other or subsequent breach or condition, whether of like or different
nature. 

15.    Optionee Undertaking.
The Optionee hereby agrees to take whatever additional actions and execute
whatever additional documents the Corporation may in its reasonable judgment
deem necessary or advisable in order to carry out or effect one or more of the
obligations or restrictions imposed on the Optionee pursuant to the express
provisions of this Agreement. 

16.    Modification of
Rights. The rights of the Optionee are subject to modification
and termination in certain events as provided in this Agreement and the Plan.

17.    Governing Law. This
Agreement shall be governed by, and construed in accordance with, the laws of

20.    Severability. In the
event one or more of the provisions of this Agreement should, for any reason, be
held to be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provisions of this
Agreement, and this Agreement shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein.

21.    WAIVER OF JURY

3.     Rights as Shareholder; Shares
Subject to Stockholders Agreement. Until the stock certificate evidencing
such Shares is issued (as evidenced by the appropriate entry on the books of the
Corporation or of a duly authorized transfer agent of the Corporation), no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Shares, notwithstanding the exercise of the Option. The
Corporation shall issue (or cause to be issued) such stock certificate promptly
after the Effective Date, provided the applicable price has been paid and the
required documents have been received. No adjustment will be made for a dividend
or other right for which the record date is prior to the date the stock
certificate is issued, except as otherwise provided in the Plan. Unless waived
by the Corporation in writing, the Shares shall automatically become subject to
the terms and conditions of any stockholders agreement or similar agreement to
which a majority of the outstanding capital stock of the Corporation is subject

issuance of the Shares such joinder agreement, signature pages or other
documents in order to evidence the Optionee’s agreement to be so bound.

Optionee understands that the Optionee may suffer adverse tax consequences as a
result of the Optionee’s purchase or disposition of the Shares. The Optionee
represents that the Optionee has consulted with any tax consultants the Optionee

that the Optionee is not relying on the Corporation for any tax advice. 

5.     Successors and Assigns. The
Corporation may assign any of its rights under the Stock Option Agreement to
single or multiple assignees (who may be stockholders, officers, directors, employees or consultants of the Corporation), and this
Agreement shall inure to the benefit of the successors and assigns of the
Corporation. Subject to the restrictions on transfer set forth in the Stock
Option Agreement, this Agreement shall be binding upon the Optionee and his or
her heirs, executors, administrators, successors and assigns.

6.     Interpretation. Any dispute
  regarding the interpretations of this Agreement shall be submitted by the
  Optionee or by the Corporation forthwith to the Committee, which shall review
  such dispute at its next regular meeting. The resolution of such a dispute by
  the Committee shall be final and binding on the Corporation and on the Optionee.

7.     Governing Laws: Severability.
This Agreement shall be governed by, and construed in accordance with, the laws
of the State of Nevada applicable to contracts made and to be wholly performed
therein, without giving effect to its conflicts of laws principles. Should any
provision of this Agreement be determined by a court of law to be illegal or
unenforceable, the other provisions shall nevertheless remain effective and
shall remain enforceable. 

8.     Notices. Any notice required
or permitted hereunder shall be given in writing and shall be deemed effectively
given if given in the manner specified in the Stock Option Agreement.

parties agree to execute such further instruments and to take such further
action as may be reasonably necessary to carry out the purposes and intent of
this Agreement.

Agreement, and the Investment Representation Statement constitute the entire

and agreements of the Corporation and the Optionee with respect to the subject
matter hereof.

	SECURITY: 	Common

	AMOUNT: 	 
    
	 	 
	DATE: 	 
    

In connection with the purchase of the above-listed Securities,
the undersigned Optionee represents to the Corporation the following: 

(a)     The Optionee is aware of the
Corporation’s business affairs and financial condition and has acquired
sufficient information about the Corporation to reach an informed and
knowledgeable decision to acquire the Securities. The Optionee is acquiring
these Securities for investment for the Optionee’s own account only and not with
a view to, or for resale in connection with, a “distribution” thereof within the
meaning of the Securities Act of 1933, as amended (the “Securities Act”).

(b)     The Optionee acknowledges and
understands that the Securities constitute “restricted securities” under the
Securities Act and have not been registered under the Securities Act in reliance
upon a specific exemption therefrom, which exemption depends upon, among other
things, the bona fide nature of the Optionee’s investment intent as expressed
herein. In this connection, the Optionee understands that, in the view of the
Securities and Exchange Commission, the statutory basis for such exemption may
be unavailable if the Optionee’s representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future. The Optionee further understands that the
Securities must be held indefinitely unless they are subsequently registered
under the Securities Act or an exemption from such registration is available.
The Optionee further acknowledges and understands that the Corporation is under
no obligation to register the Securities. The Optionee understands that the
certificate evidencing the Securities will be imprinted with a legend which
prohibits the transfer of the Securities unless they are registered or such
registration is not required in the opinion of counsel satisfactory to the
Corporation and other legends required under the applicable state or federal
securities laws.

 Article 2. THE NOTES 

Section 2.01. FORM, DATING AND DENOMINATIONS. 

The Notes and the Trustee’s certificate of authentication will be substantially in the form set forth in Exhibit
A. The Notes will bear the legends required by Section 2.09 and may bear notations, legends or endorsements required by law, stock exchange rule or usage or the Depositary. Each Note will be dated as of the date of its
authentication. 
 Except to the extent otherwise provided in a Company Order delivered to the Trustee in connection with
the issuance and authentication thereof, the Notes will be issued initially in the form of one or more Global Notes. Global Notes may be exchanged for Physical Notes, and Physical Notes may be exchanged for Global Notes, only as provided in
Section 2.10. 
 The Notes will be issuable only in registered form without interest coupons and
only in Authorized Denominations. 
 Each certificate representing a Note will bear a unique registration number that is not
affixed to any other certificate representing another outstanding Note. 
 The terms contained in the Notes constitute part
of this Indenture, and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, agree 

  
 - 13 - 

 
to such terms and to be bound thereby; provided, however, that, to the extent that any provision of any Note conflicts with the provisions of this Indenture, the provisions of this
Indenture will control for purposes of this Indenture and such Note. 
 Section 2.02. EXECUTION,
AUTHENTICATION AND DELIVERY. 
 (A) Due Execution by the Company. At
least one (1) duly authorized Officer will sign the Notes on behalf of the Company by manual or facsimile signature. A Note’s validity will not be affected by the failure of any Officer whose signature is on any Note to hold, at the time
such Note is authenticated, the same or any other office at the Company. 
 (B) Authentication by the Trustee and

 (i) No Note will be valid until it is authenticated by the Trustee. A Note will be deemed to
be duly authenticated only when an authorized signatory of the Trustee (or a duly appointed authenticating agent) manually signs the certificate of authentication of such Note. 

(ii) The Trustee will cause an authorized signatory of the Trustee (or a duly appointed authenticating agent)
to manually sign the certificate of authentication of a Note only if (1) the Company delivers such Note to the Trustee; (2) such Note is executed by the Company in accordance with Section 2.02(A); and (3) the Company delivers a

first Interest Payment Date and the Last Original Issue 

  
 - 14 - 

 
Date of such additional Notes), which additional Notes will, subject to the foregoing, be considered to be part of the same series of, and rank equally and ratably with all other, Notes issued
under this Indenture; provided, however, that if any such additional Notes are not fungible with other Notes issued under this Indenture for federal income tax or federal securities laws purposes, then such additional Notes will be
identified by a separate CUSIP number or by no CUSIP number. In authenticating additional Notes, the Trustee will receive: 

(i) a copy of the resolution or resolutions of the Board of Directors in or pursuant to which the terms and
form of the Notes were established, and if the terms and form of such Notes are established by an Officer’s Certificate pursuant to general authorization of the Board of Directors, such Officer’s Certificate; 

(ii) an executed supplemental indenture, if any; and 

(iii) an Opinion of Counsel which will state:

Indenture; and 
 (2) that such Notes, when authenticated and delivered by the Trustee and issued by the
Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency,
reorganization and other laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles. 

Section 2.04. METHOD OF PAYMENT. 

(A) Global Notes. The Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on
the Maturity Date, Redemption on a Redemption Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash Conversion Consideration for, any Global Note to the Depositary by wire transfer of immediately
available funds no later than the time the same is due as provided in this Indenture. 
 (B) Physical Notes. The
Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on the Maturity Date, Redemption on a Redemption Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash
Conversion Consideration for, any Physical Note no later than the time the same is due as provided in this Indenture as follows: (i) if the principal amount of such Physical Note is at least five million dollars ($5,000,000) (or such lower
amount as the Company may choose in its sole and absolute discretion) and the Holder of such Physical Note entitled to such payment has delivered to the Paying Agent or the Trustee, no later than the time set forth in the immediately following
sentence, a written request that the Company make such payment by wire transfer to an account of such Holder within the United States, by wire transfer of immediately available funds to such account; and (ii) in all other cases, by check mailed
to the address of the Holder of such Physical Note entitled to such payment as set forth in the Register. To be timely, such written request must be so delivered no later than the Close of Business on the following date:

  
 - 15 - 

 
(x) with respect to the payment of any interest due on an Interest Payment Date, the immediately preceding Regular Record Date; (y) with respect to any cash Conversion Consideration, the
relevant Conversion Date; and (z) with respect to any other payment, the date that is fifteen (15) calendar days immediately before the date such payment is due. 

Section 2.05. ACCRUAL OF INTEREST; DEFAULTED AMOUNTS;
WHEN PAYMENT DATE IS NOT A BUSINESS DAY. 

(A) Accrual of Interest. Each Note will accrue interest at a rate per annum equal to 2.25% (the “Stated
Interest”), plus any Additional Interest and Special Interest that may accrue pursuant to Sections 3.04 and 7.03, respectively. Stated Interest on each Note will (i) accrue from, and including, the most recent date
to which Stated Interest has been paid or duly provided for (or, if no Stated Interest has theretofore been paid or duly provided for, the date set forth in the certificate representing such Note as the date from, and including, which Stated
Interest will begin to accrue in such circumstance) to, but excluding, the date of payment of such Stated Interest; and (ii) be, subject to Sections 4.02(D), 4.03(E) and 5.02(D) (but without duplication of any
payment of interest), payable semi-annually in arrears on each Interest Payment Date, beginning on the first Interest Payment Date set forth in the certificate representing such Note, to the Holder of such Note as of the Close of Business on the
immediately preceding Regular Record Date. Stated Interest, and, if applicable, Additional Interest and Special Interest, on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (B) Defaulted Amounts. If the Company fails to pay any amount (a
“Defaulted Amount”) payable on a Note on or before the due date therefor as provided in this Indenture, then, regardless of whether such failure constitutes an Event of Default, (i) such Defaulted Amount will forthwith cease to
be payable to the Holder of such Note otherwise entitled to such payment; (ii) to the extent lawful, interest (“Default Interest”) will accrue on such Defaulted Amount at a rate per annum equal to the rate per annum at which
Stated Interest accrues, from, and including, such due date to, but excluding, the date of payment of such Defaulted Amount and Default Interest; (iii) such Defaulted Amount and Default Interest will be paid on a payment date selected by the
Company to the Holder of such Note as of the Close of Business on a special record date selected by the Company, provided that such special record date must be no more than fifteen (15), nor less than ten (10), calendar days before such
payment date; and (iv) at least fifteen (15) calendar days before such special record date, the Company will send notice to the Trustee and the Holders that states such special record date, such payment date and the amount of such
Defaulted Amount and Default Interest to be paid on such payment date. 
 (C) Delay of Payment when Payment Date is Not a
Business Day. If the due date for a payment on a Note as provided in this Indenture is not a Business Day, then, notwithstanding anything to the contrary in this Indenture or the Notes, such payment may be made on the immediately following
Business Day and no interest will accrue on such payment as a result of the related delay. Solely for purposes of the immediately preceding sentence, a day on which the applicable place of payment is authorized or required by law or executive order
to close or be closed will be deemed not to be a “Business Day.” 

  
 - 16 - 

 Section 2.06. REGISTRAR, PAYING AGENT AND
CONVERSION AGENT. 
 (A) Generally. The Company will maintain (i) an office or
agency in the continental United States where Notes may be presented for registration of transfer or for exchange (the “Registrar”); (ii) an office or agency in the continental United States where Notes may be presented for payment
(the “Paying Agent”); and (iii) an office or agency in the continental United States where Notes may be presented for conversion (the “Conversion Agent”). If the Company fails to maintain a Registrar, Paying
Agent or Conversion Agent, then the Trustee will act as such. For the avoidance of doubt, the Company or any of its Subsidiaries may act as Registrar, Paying Agent or Conversion Agent. 

(B) Duties of the Registrar. The Registrar will keep a record (the “Register”) of the names and
addresses of the Holders, the Notes held by each Holder and the transfer, exchange, repurchase, Redemption and conversion of Notes. Absent manifest error, the entries in the Register will be conclusive and the Company and the Trustee may treat each
Person whose name is recorded as a Holder in the Register as a Holder for all purposes. The Register will be in written form or in any form capable of being converted into written form reasonably promptly. 

(C) Co-Agents; Company’s Right to Appoint Successor Registrars, Paying Agents
and Conversion Agents. The Company may appoint one or more co-Registrars, co-Paying Agents and co-Conversion Agents, each of
whom will be deemed to be a Registrar, Paying Agent or Conversion Agent, as applicable, under this Indenture. Subject to Section 2.06(A), the Company may change any Registrar, Paying Agent or Conversion Agent (including appointing itself or
any of its Subsidiaries to act in such capacity) without prior notice to any Holder. The Company will notify the Trustee (and, upon request, any Holder) of the name and address of each Note Agent, if any, not a party to this Indenture and will enter
into an appropriate agency agreement with each such Note Agent, which agreement will implement the provisions of this Indenture that relate to such Note Agent. 

(D) Initial Appointments. The Company appoints the Trustee as the initial Paying Agent, the initial Registrar and the
initial Conversion Agent. 
 Section 2.07. PAYING AGENT AND CONVERSION
AGENT TO HOLD PROPERTY IN TRUST. 

The Company will require each Paying Agent or Conversion Agent that is not the Trustee to agree in writing that such Note Agent
will (A) hold in trust for the benefit of Holders or the Trustee all money and other property held by such Note Agent for payment or delivery due on the Notes; and (B) notify the Trustee of any default by the Company in making any such
payment or delivery. The Company, at any time, may, and the Trustee, while any Default continues, may, require a Paying Agent or Conversion Agent to pay or deliver, as applicable, all money and other property held by it to the Trustee, after which
payment or delivery, as applicable, such Note Agent (if not the Company or any of its Subsidiaries) will have no further liability for such money or property. If the Company or any of its Subsidiaries acts as Paying Agent or Conversion Agent, then
(A) it will segregate and hold in a separate account for the benefit of the Holders or the Trustee all money and other property held by it as Paying Agent or Conversion Agent; and (B) references in this Indenture or the Notes to the Paying
Agent or Conversion Agent holding cash or other property, or to the delivery of cash or other property to 

  
 - 17 - 

 
the Paying Agent or Conversion Agent, in each case for payment or delivery to any Holders or the Trustee or with respect to the Notes, will be deemed refer to cash or other property so segregated
and held separately, or to the segregation and separate holding of such cash or other property, respectively. Upon the occurrence of any event in clause (viii) or (ix) of Section 7.01(A) with respect to the Company
(or with respect to any Subsidiary of the Company acting as Paying Agent or Conversion Agent), the Trustee will serve as the Paying Agent or Conversion Agent, as applicable, for the Notes. 

SECTION 2.08. HOLDER LISTS. 

If the Trustee is not the Registrar, the Company will furnish to the Trustee, no later than seven (7) Business Days before
each Interest Payment Date, and at such other times as the Trustee may request, a list, in such form and as of such date or time as the Trustee may reasonably require, of the names and addresses of the Holders. 

SECTION 2.09. LEGENDS. 

(A) Global Note Legend. Each Global Note will bear the Global Note Legend (or any similar legend, not inconsistent with
this Indenture, required by the Depositary for such Global Note). 
 (B)
Non-Affiliate Legend. Each Note will bear the Non-Affiliate Legend. 

(C) Restricted Note Legend. Subject to Section 2.12, 

(i) each Note that is a Transfer-Restricted Security will bear the Restricted Note Legend; and 

(ii) if a Note is issued in exchange for, in substitution of, or to effect a partial conversion of, another
Note (such other Note being referred to as the “old Note” for purposes of this Section 2.09(C)(ii)), including pursuant to Section 2.10(B), 2.10(C), 2.11 or 2.13, such Note will bear the Restricted Note
Legend if such old Note bore the Restricted Note Legend at the time of such exchange or substitution, or on the related Conversion Date with respect to such conversion, as applicable; provided, however, that such Note need not bear the
Restricted Note Legend if such Note does not constitute a Transfer-Restricted Security immediately after such exchange or substitution, or as of such Conversion Date, as applicable. 

(D) Other Legends. A Note may bear any other legend or text, not inconsistent with this Indenture, as may be required
by applicable law or by any securities exchange or automated quotation system on which such Note is traded or quoted. 
 (E)
Acknowledgement and Agreement by the Holders. A Holder’s acceptance of any Note bearing any legend required by this Section 2.09 will constitute such Holder’s acknowledgement of, and agreement to comply
with, the restrictions set forth in such legend. 
 (F) Restricted Stock Legend. 

  
 - 18 - 

 (i) Each Conversion Share will bear the Restricted Stock Legend
if the Note upon the conversion of which such Conversion Share was issued was (or would have been had it not been converted) a Transfer-Restricted Security at the time such Conversion Share was issued; provided, however, that such
Conversion Share need not bear the Restricted Stock Legend if the Company determines, in its reasonable discretion, that such Conversion Share need not bear the Restricted Stock Legend. 

(ii) Notwithstanding anything to the contrary in this Section 2.09(F), a Conversion Share need not bear
a Restricted Stock Legend if such Conversion Share is issued in an uncertificated form that does not permit affixing legends thereto, provided the Company takes measures (including the assignment thereto of a “restricted” CUSIP
number) that it reasonably deems appropriate to enforce the transfer restrictions referred to in the Restricted Stock Legend. 

Section 2.10. TRANSFERS AND EXCHANGES; CERTAIN TRANSFER
RESTRICTIONS. 
 (A) Provisions Applicable to All Transfers and Exchanges. 

(i) Subject to this Section 2.10, Physical Notes and beneficial interests in Global
Notes may be transferred or exchanged from time to time and the Registrar will record each such transfer or exchange in the Register. 

(ii) Each Note issued upon transfer or exchange of any other Note (such other Note being referred to as the
“old Note” for purposes of this Section 2.10(A)(ii)) or portion thereof in accordance with this Indenture will be the valid obligation of the Company, evidencing the same indebtedness, and entitled to the same benefits under this
Indenture, as such old Note or portion thereof, as applicable. 
 (iii) The Company, the Trustee and the Note
Agents will not impose any service charge on any Holder for any transfer, exchange or conversion of Notes, but the Company, the Trustee, the Registrar and the Conversion Agent may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Notes, other than exchanges pursuant to Sections 2.11, 2.17 or 8.05 not involving any transfer. 

(iv) Notwithstanding anything to the contrary in this Indenture or the Notes, a Note may not be transferred or
exchanged in part unless the portion to be so transferred or exchanged is in an Authorized Denomination. 

(v) The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with any
transfer restrictions imposed under this Indenture or applicable law with respect to any Security, other than to require the delivery of such certificates or other documentation or evidence as expressly required by this Indenture and to examine the
same to determine substantial compliance as to form with the requirements of this Indenture. 
 (vi) Each
Note issued upon transfer of, or in exchange for, another Note will bear each legend, if any, required by Section 2.09. 

  
 - 19 - 

 (vii) Upon satisfaction of the requirements of this Indenture to
effect a transfer or exchange of any Note, the Company will cause such transfer or exchange to be effected as soon as reasonably practicable but in no event later than the third (3rd) (or, if the T+2 Effective Date has occurred by the date of such
satisfaction, the second (2nd)) Business Day after the date of such satisfaction. 
 (viii) For the avoidance
of doubt, and subject to the terms of this Indenture, as used in this Section 2.10, an “exchange” of a Global Note or a Physical Note includes (x) an exchange effected for the sole purpose of removing any
Restricted Note Legend affixed to such Global Note or Physical Note; and (y) if such Global Note or a Physical Note is identified by a “restricted” CUSIP number, an exchange effected for the sole purpose of causing such Global Note or
a Physical Note to be identified by an “unrestricted” CUSIP number. 
 (ix) Neither the Trustee nor
any Note Agent will be responsible for any actions taken or not taken by the Depositary. 
 (B) Transfers and Exchanges
of Global Notes. 
 (i) Subject to the immediately following sentence, no Global Note may be transferred
or exchanged in whole except (1) by the Depositary to a nominee of the Depositary; (2) by a nominee of the Depositary to the Depositary or to another nominee of the Depositary; or (3) by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. No Global Note (or any portion thereof) may be transferred to, or exchanged for, a Physical Note; provided, however, that a Global Note will be exchanged, pursuant to
customary procedures, for one or more Physical Notes if: 
 (1) (x) the Depositary notifies the Company or
the Trustee that the Depositary is unwilling or unable to continue as depositary for such Global Note or (y) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act and, in each case, the
Company fails to appoint a successor Depositary within ninety (90) days of such notice or cessation; 

(2) an Event of Default has occurred and is continuing and the Company, the Trustee or the Registrar has
received a written request from the Depositary, or from a holder of a beneficial interest in such Global Note, to exchange such Global Note or beneficial interest, as applicable, for one or more Physical Notes; or 

(3) the Company, in its sole discretion, permits the exchange of any beneficial interest in such Global Note
for one or more Physical Notes at the request of the owner of such beneficial interest. 
 (ii) Upon
satisfaction of the requirements of this Indenture to effect a transfer or exchange of any Global Note (or any portion thereof): 

(1) the Trustee will reflect any resulting decrease of the principal

  
 - 20 - 

 
amount of such Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if such notation results in such Global Note
having a principal amount of zero, the Company may (but is not required to) instruct the Trustee to cancel such Global Note pursuant to Section 2.15); 

(2) if required to effect such transfer or exchange, then the Trustee will reflect any resulting increase of
the principal amount of any other Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such other Global Note; 

(3) if required to effect such transfer or exchange, then the Company will issue, execute and deliver, and the
Trustee will authenticate, in each case in accordance with Section 2.02, a new Global Note bearing each legend, if any, required by Section 2.09; and 

(4) if such Global Note (or such portion thereof), or any beneficial interest therein, is to be exchanged for
one or more Physical Notes, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that are in Authorized Denominations
(not to exceed, in the aggregate, the principal amount of such Global Note to be so exchanged), are registered in such name(s) as the Depositary specifies (or as otherwise determined pursuant to customary procedures) and bear each legend, if any,
required by Section 2.09. 
 (iii) Each transfer or exchange of a beneficial
interest in any Global Note will be made in accordance with the Depositary Procedures. 
 (C) Transfers and Exchanges of
Physical Notes. 
 (i) Subject to this Section 2.10, a Holder of a Physical
Note may (x) transfer such Physical Note (or any portion thereof in an Authorized Denomination) to one or more other Person(s); (y) exchange such Physical Note (or any portion thereof in an Authorized Denomination) for one or more other
Physical Notes in Authorized Denominations having an aggregate principal amount equal to the aggregate principal amount of the Physical Note (or portion thereof) to be so exchanged; and (z) if then permitted by the Depositary Procedures,
transfer such Physical Note (or any portion thereof in an Authorized Denomination) in exchange for a beneficial interest in one or more Global Notes; provided, however, that, to effect any such transfer or exchange, such Holder must:

 (1) surrender such Physical Note to be transferred or exchanged to the office of the Registrar, together
with any endorsements or transfer instruments reasonably required by the Company, the Trustee or the Registrar; and 

(2) deliver such certificates, documentation or evidence as may be required pursuant to Section 2.10(D).

  
 - 21 - 

 (ii) Upon the satisfaction of the requirements of this Indenture
to effect a transfer or exchange of any Physical Note (such Physical Note being referred to as the “old Physical Note” for purposes of this Section 2.10(C)(ii)) of a Holder (or any portion of such old Physical Note in an Authorized
Denomination): 
 (1) such old Physical Note will be promptly cancelled pursuant to
Section 2.15; 
 (2) if such old Physical Note is to be transferred or exchanged
only in part, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and
have an aggregate principal amount equal to the principal amount of such old Physical Note not to be transferred or exchanged; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by
Section 2.09; 
 (3) in the case of a transfer: 

(a) to the Depositary or a nominee thereof that will hold its interest in such old Physical Note (or such
portion thereof) to be so transferred in the form of one or more Global Notes, the Trustee will reflect an increase of the principal amount of one or more existing Global Notes by notation on the “Schedule of Exchanges of Interests in the
Global Note” forming part of such Global Note(s), which increase(s) are in Authorized Denominations and aggregate to the principal amount to be so transferred, and which Global Note(s) bear each legend, if any, required by
Section 2.09; provided, however, that if such transfer cannot be so effected by notation on one or more existing Global Notes (whether because no Global Notes bearing each legend, if any, required by
Section 2.09 then exist, because any such increase will result in any Global Note having an aggregate principal amount exceeding the maximum aggregate principal amount permitted by the Depositary or otherwise), then the
Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Global Notes that (x) are in Authorized Denominations and have an aggregate
principal amount equal to the principal amount to be so transferred; and (y) bear each legend, if any, required by Section 2.09; and 

(b) to a transferee that will hold its interest in such old Physical Note (or such portion thereof) to be so
transferred in the form of one or more Physical Notes, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that
(x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so transferred; (y) are registered in the name of such transferee; and (z) bear each legend, if any, required by
Section 2.09; and 

  
 - 22 - 

 (4) in the case of an exchange, the Company will issue, execute
and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the
principal amount to be so exchanged; (y) are registered in the name of the Person to whom such old Physical Note was registered; and (z) bear each legend, if any, required by Section 2.09. 

(D) Requirement to Deliver Documentation and Other Evidence. If a Holder of any Note that is identified by a
“restricted” CUSIP number or that bears a Restricted Note Legend or is a Transfer-Restricted Security requests to: 

(i) cause such Note to be identified by an “unrestricted” CUSIP number; 

(ii) remove such Restricted Note Legend; or 

(iii) register the transfer of such Note to the name of another Person, 

then the Company, the Trustee and the Registrar may refuse to effect such identification, removal or transfer, as applicable, unless there is
delivered to the Company, the Trustee and the Registrar such certificates or other documentation or evidence as the Company, the Trustee and the Registrar may reasonably require to determine that such identification, removal or transfer, as
applicable, complies with the Securities Act and other applicable securities laws; provided, however, that no such certificates, documentation or evidence need be so delivered on and after the Free Trade Date with respect to such Note
unless the Company determines, in its reasonable discretion, that such Note is not eligible to be offered, sold or otherwise transferred pursuant to Rule 144 or otherwise without any requirements as to volume, manner of sale, availability of current
public information or notice under the Securities Act. 
 (E) Transfers of Notes Subject to Redemption, Repurchase or
Conversion. Notwithstanding anything to the contrary in this Indenture or the Notes, the Company, the Trustee and the Registrar will not be required to register the transfer of or exchange any Note that (i) has been surrendered for
conversion, except to the extent that any portion of such Note is not subject to conversion; (ii) is subject to a Fundamental Change Repurchase Notice validly delivered, and not withdrawn, pursuant to Section 4.02(F), except to the
extent that any portion of such Note is not subject to such notice or the Company fails to pay the applicable Fundamental Change Repurchase Price when due; or (iii) has been selected for Redemption pursuant to a Redemption Notice, except to the
extent that any portion of such Note is not subject to Redemption or the Company fails to pay the applicable Redemption Price when due. 

Section 2.11. EXCHANGE AND CANCELLATION OF NOTES
TO BE CONVERTED, REDEEMED OR REPURCHASED. 

(A) Partial Conversions, Redemptions and Repurchases of Physical Notes. If only a portion of a Physical Note of a
Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change or Redemption, then, as soon as reasonably practicable after such Physical Note is surrendered for such conversion or repurchase,
the 

  
 - 23 - 

 
Company will cause such Physical Note to be exchanged, pursuant and subject to Section 2.10(C), for (i) one or more Physical Notes that are in Authorized Denominations and have an
aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased, and deliver such Physical Note(s) to such Holder; and (ii) a Physical Note having a principal amount equal to the
principal amount to be so converted or repurchased, which Physical Note will be converted or repurchased, as applicable, pursuant to the terms of this Indenture; provided, however, that the Physical Note referred to in this clause
(ii) need not be issued at any time after which such principal amount subject to such conversion or repurchase is deemed to cease to be outstanding pursuant to Section 2.18. 

(B) Cancellation of Converted, Redeemed and Repurchased Notes. 

(i) Physical Notes. If a Physical Note (or any portion thereof that has not theretofore been exchanged
pursuant to Section 2.11(A)) of a Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change or Redemption, then, promptly after the later of the time such Physical Note (or
such portion) is deemed to cease to be outstanding pursuant to Section 2.18 and the time such Physical Note is surrendered for such conversion or repurchase, as applicable, (1) such Physical Note will be cancelled
pursuant to Section 2.15; and (2) in the case of a partial conversion or repurchase, the Company will issue, execute and deliver to such Holder, and the Trustee will authenticate, in each case in accordance with
Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or
repurchased; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by Section 2.09. 

(ii) Global Notes. If a Global Note (or any portion thereof) is to be converted pursuant to Article
5 or repurchased pursuant to a Repurchase Upon Fundamental Change or Redemption, then, promptly after the time such Note (or such portion) is deemed to cease to be outstanding pursuant to Section 2.18, the Trustee will
reflect a decrease of the principal amount of such Global Note in an amount equal to the principal amount of such Global Note to be so converted or repurchased, as applicable, by notation on the “Schedule of Exchanges of Interests in the Global
Note” forming part of such Global Note (and, if the principal amount of such Global Note is zero following such notation, cancel such Global Note pursuant to Section 2.15). 

Section 2.12. REMOVAL OF TRANSFER RESTRICTIONS. 

Without limiting the generality of any other provision of this Indenture (including Section 3.04),
the Restricted Note Legend affixed to any Note will be deemed, pursuant to this Section 2.12 and the footnote to such Restricted Note Legend, to be removed therefrom upon the Company’s delivery to the Trustee of notice
to such effect. If such Note bears a “restricted” CUSIP or ISIN number at the time of such delivery, then, upon such delivery, such Note will be deemed, pursuant to this Section 2.12 and the footnotes to the CUSIP
and ISIN numbers set forth on the face of the certificate representing such Note, to thereafter bear the “unrestricted” CUSIP and ISIN numbers identified in such footnotes; provided, however, that if such Note is a Global
Note and the Depositary thereof requires a mandatory exchange or other procedure to cause such 

  
 - 24 - 

 
Global Note to be identified by “unrestricted” CUSIP and ISIN numbers in the facilities of such Depositary, then (i) the Company will effect such exchange or procedure as soon as
reasonably practicable; and (ii) for purposes of Section 3.04 and the definition of Freely Tradable, such Global Note will not be deemed to be identified by “unrestricted” CUSIP and ISIN numbers until such
time as such exchange or procedure is effected. 
 Section 2.13. REPLACEMENT NOTES. 

If a Holder of any Note claims that such Note has been mutilated, lost, destroyed or wrongfully taken, then the Company will
issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a replacement Note upon surrender to the Trustee of such mutilated Note, or upon delivery to the Trustee of
evidence of such loss, destruction or wrongful taking reasonably satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Note, the Company and the Trustee may require the Holder thereof to provide such
security or indemnity that is reasonably satisfactory to the Company and the Trustee to protect the Company and the Trustee from any loss that any of them may suffer if such Note is replaced. 

Every replacement Note issued pursuant to this Section 2.13 will be an additional obligation of the
Company and will be entitled to all of the benefits of this Indenture equally and ratably with all other Notes issued under this Indenture. 

Section 2.14. REGISTERED HOLDERS; CERTAIN RIGHTS WITH
RESPECT TO GLOBAL NOTES. 
 Only the Holder of a Note will
have rights under this Indenture as the owner of such Note. Without limiting the generality of the foregoing, Depositary Participants will have no rights as such under this Indenture with respect to any Global Note held on their behalf by the
Depositary or its nominee, or by the Trustee as its custodian, and the Company, the Trustee and the Note Agents, and their respective agents, may treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever;
provided, however, that (A) the Holder of any Global Note may grant proxies and otherwise authorize any Person, including Depositary Participants and Persons that hold interests in Notes through Depositary Participants, to take
any action that such Holder is entitled to take with respect to such Global Note under this Indenture or the Notes; and (B) the Company and the Trustee, and their respective agents, may give effect to any written certification, proxy or other
authorization furnished by the Depositary. 
 Section 2.15. CANCELLATION. 

Without limiting the generality of Section 3.08, the Company may at any time deliver Notes to the
Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent will forward to the Trustee each Note duly surrendered to them for transfer, exchange, payment or conversion. The Trustee will promptly cancel all Notes so
surrendered to it accordance with its customary procedures. Without limiting the generality of Section 2.03(B), the Company may not originally issue new Notes to replace Notes that it has paid or that have been cancelled upon transfer,
exchange, payment or conversion. 

  
 - 25 - 

 Section 2.16. NOTES HELD BY THE
COMPANY OR ITS AFFILIATES. 
 Without limiting the generality
of Section 3.08, in determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any of its Affiliates will be deemed
not to be outstanding; provided, however, that, for purposes of determining whether the Trustee is protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are
so owned will be so disregarded. 
 Section 2.17. TEMPORARY NOTES. 

Until definitive Notes are ready for delivery, the Company may issue, execute and deliver, and the Trustee will authenticate,
in each case in accordance with Section 2.02, temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. The
Company will promptly prepare, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, definitive Notes in exchange for temporary Notes. Until so exchanged, each
temporary Note will in all respects be entitled to the same benefits under this Indenture as definitive Notes. 
 Section 2.18.
OUTSTANDING NOTES. 
 (A) Generally. The Notes that are outstanding at any time will
be deemed to be those Notes that, at such time, have been duly executed and authenticated, excluding those Notes (or portions thereof) that have theretofore been (i) cancelled by the Trustee or delivered to the Trustee for cancellation in
accordance with Section 2.15; (ii) assigned a principal amount of zero by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of any a Global Note representing such Note;
(iii) paid in full in accordance with this Indenture; or (iv) deemed to cease to be outstanding to the extent provided in, and subject to, clause (B), (C) or (D) of this Section 2.18.

 (B) Replaced Notes. If a Note is replaced pursuant to Section 2.13, then such Note will
cease to be outstanding at the time of its replacement, unless the Trustee and the Company receive proof reasonably satisfactory to them that such Note is held by a “bona fide purchaser” under applicable law. 

(C) Maturing Notes and Notes Called for Redemption or Subject to Repurchase. If, on a Redemption Date, a Fundamental
Change Repurchase Date or the Maturity Date, the Paying Agent holds money sufficient to pay the aggregate Redemption Price, Fundamental Change Repurchase Price or principal amount, respectively, together, in each case, with the aggregate interest,
in each case due on such date, then (unless there occurs a Default in the payment of any such amount) (i) the Notes (or portions thereof) to be redeemed or repurchased, or that mature, on such date will be deemed, as of such date, to cease to
be outstanding, except to the extent provided in Sections 4.02(D), 4.03(E) or 5.02(D); and (ii) the rights of the Holders of such Notes (or such portions thereof), as such, will terminate with respect to such Notes (or such
portions thereof), other than the right to receive the Redemption Price, Fundamental Change Repurchase Price or principal amount, as applicable, of, and accrued and unpaid interest on, such Notes (or

  
 - 26 - 

 
such portions thereof), in each case as provided in this Indenture. 

(D) Notes to Be Converted. At the Close of Business on the Conversion Date for any Note (or any portion thereof) to be
converted, such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due, pursuant to Section 5.03(B) or Section 5.02(D), upon such conversion) be deemed to cease to be
outstanding, except to the extent provided in Section 5.02(D) or Section 5.08. 
 (E)
Cessation of Accrual of Interest. Except as provided in Sections 4.02(D), 4.03(E) or 5.02(D), interest will cease to accrue on each Note from, and including, the date that such Note is deemed, pursuant to this
Section 2.18, to cease to be outstanding, unless there occurs a default in the payment or delivery of any cash or other property due on such Note. 

Section 2.19. REPURCHASES BY THE COMPANY. 

Without limiting the generality of Section 2.15, the Company or its Subsidiaries may, from time to
time, directly or indirectly, repurchase Notes in open market purchases or otherwise, whether through private or public tender or exchange offers, cash-settled swaps or other derivatives without delivering prior notice to Holders. 

Section 2.20. CUSIP AND ISIN NUMBERS. 

Subject to Section 2.12, the Company may use one or more CUSIP or ISIN numbers to identify any of the
Notes, and, if so, the Company and the Trustee will use such CUSIP or ISIN number(s) in notices to Holders; provided, however, that (i) the Trustee makes no representation as to the correctness or accuracy of any such CUSIP or
ISIN number; and (ii) the effectiveness of any such notice will not be affected by any defect in, or omission of, any such CUSIP or ISIN number. The Company will promptly notify the Trustee of any change in the CUSIP or ISIN number(s)
identifying any Notes. 
 Article 3. COVENANTS 

Section 3.01. PAYMENT ON NOTES. 

(A) Generally. The Company will pay or cause to be paid all the principal of, the Fundamental Change Repurchase Price
and Redemption Price for, interest on, and other amounts due with respect to, the Notes on the dates and in the manner set forth in this Indenture. 

(B) Deposit of Funds. Before 1:00 p.m., New York City time, on each Redemption Date, Fundamental Change Repurchase Date
or Interest Payment Date, and on the Maturity Date or any other date on which any cash amount is due on the Notes, the Company will deposit, or will cause there to be deposited, with the Paying Agent cash, in funds immediately available on such
date, sufficient to pay the cash amount due on the applicable Notes on such date. The Paying Agent will return to the Company, as soon as practicable, any money not required for such purpose. 

  
 - 27 - 

 Section 3.02. EXCHANGE ACT REPORTS. 

(A) Generally. The Company will send to the Trustee copies of all annual or quarterly reports (on Form 10-K or Form 10-Q, or any respective successor forms) that the Company is required to file with or furnish to the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act
within fifteen (15) calendar days after the date that the Company is required to file or furnish the same (after giving effect to all applicable grace periods under the Exchange Act); provided, however, that the Company need not
send to the Trustee any material for which the Company has received, or is seeking in good faith and has not been denied, confidential treatment by the SEC. Any report that the Company files with or furnishes to the SEC through the EDGAR system (or
any successor thereto) will be deemed to be sent to the Holders at the time such report is so filed or furnished via the EDGAR system (or such successor). 

(B) Trustee’s Disclaimer. The Trustee need not determine whether the Company has filed or furnished any material
via the EDGAR system (or such successor). The sending, filing or furnishing of reports pursuant to this Section 3.02(A) will not be deemed to constitute constructive notice to the Trustee of any information contained, or determinable from
information contained, therein, including the Company’s compliance with any of its covenants under this Indenture. The Trustee will have no liability or responsibility for the filing, timeliness or content of any such report or information.

 Section 3.03. RULE 144A INFORMATION. 

If the Company is not subject to Section 13 or 15(d) of the Exchange Act at any time when any Notes or shares of Common
Stock issuable upon conversion of the Notes are outstanding and constitute “restricted securities” (as defined in Rule 144 under the Securities Act), then the Company (or its successor) will promptly provide, to the Trustee and, upon
written request, to any Holder, beneficial owner or prospective purchaser of such Notes or shares, 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
pursuant to Rule 144A under the Securities Act. 
 Section 3.04. ADDITIONAL INTEREST. 

(A) Accrual of Additional Interest. 

(i) If, at any time during the six (6) month period beginning on, and including, the date that is six
(6) months after the Last Original Issue Date of any Note, 
 (1) the Company fails to timely file any
report (other than Form 8-K reports) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (after giving effect to all applicable grace periods thereunder);
or 
 (2) such Note is not otherwise Freely Tradable, 

then Additional Interest will accrue on such Note for each day during such period on which such failure is continuing or such
Note is not Freely Tradable. 

  
 - 28 - 

 (ii) In addition, Additional Interest will accrue on a Note on
each day on which such Note is not Freely Tradable on or after the fifteenth (15th) calendar day following the Free Trade Date of such Note. 

(B) Amount and Payment of Additional Interest. Any Additional Interest that accrues on a Note pursuant to Section
3.04(A) will be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate per annum equal to one quarter of one percent (0.25%) of the principal amount thereof for the first ninety
(90) days on which Additional Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof; provided, however, that in no event will Additional Interest, together
with any Special Interest, accrue on any day on a Note at a combined rate per annum that exceeds one half of one percent (0.50%), regardless of the number of events or circumstances giving rise to the accrual of Special Interest or Additional
Interest. For the avoidance of doubt, any Additional Interest that accrues on a Note will be in addition to the Stated Interest that accrues on such Note and, subject to the proviso of the immediately preceding sentence, in addition to any Special
Interest that accrues on such Note. 
 (C) Notice of Accrual of Additional Interest; Trustee’s Disclaimer. The
Company will send notice to the Holder of each Note, and to the Trustee, of the commencement and termination of any period in which Additional Interest accrues on such Note. In addition, if Additional Interest accrues on any Note, then, no later
than five (5) Business Days before each date on which such Additional Interest is to be paid, the Company will deliver an Officer’s Certificate to the Trustee and the Paying Agent stating (i) that the Company is obligated to pay
Additional Interest on such Note on such date of payment; and (ii) the amount of such Additional Interest that is payable on such date of payment. The Trustee will have no duty to determine whether any Additional Interest is payable or the
amount thereof. 
 Section 3.05. COMPLIANCE AND DEFAULT CERTIFICATES.

 (A) Annual Compliance Certificate. Within one hundred twenty (120) days after December 31, 2017, and
each fiscal year of the Company ending thereafter, the Company will deliver an Officer’s Certificate to the Trustee stating whether, to such signatory’s knowledge, a Default or Event of Default has occurred or is continuing (and, if so,
describing all such Defaults or Events of Default and what action the Company is taking or proposes to take with respect thereto). 

(B) Default Certificate. If a Default or Event of Default occurs, then, within thirty (30) days after its
occurrence, the Company will deliver an Officer’s Certificate to the Trustee describing the same and what action the Company is taking or proposes to take with respect thereto, except that the Company will not be required to deliver such an
Officer’s Certificate if such Default or Event of Default has been cured.

EXTENSION AND USURY LAWS. 
 To the extent that it may
lawfully do so, the Company (A) agrees that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law (wherever or whenever enacted or in force) that may
affect the 

  
 - 29 - 

 
covenants or the performance of this Indenture; and (B) expressly waives all benefits or advantages of any such law and agrees that it will not, by resort to any such law, hinder, delay or
impede the execution of any power granted to the Trustee by this Indenture, but will suffer and permit the execution of every such power as though no such law has been enacted. 

Section 3.07. CORPORATE EXISTENCE. 

Subject to Article 6, the Company will cause to preserve and keep in full force and effect: 

(A) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with
the respective organizational documents of the Company and its Subsidiaries; and 
 (B) the material rights (charter and
statutory), licenses and franchises of the Company and the Subsidiaries; 
 provided, however, that the Company need not
preserve or keep in full force and effect any such existence, right, license or franchise if the Board of Directors determines that (x) the preservation thereof is no longer desirable in the conduct of the business of the Company and its
Subsidiaries, taken as a whole; and (y) the loss thereof is not, individually or in the aggregate, materially adverse to the Holders. 

Section 3.08. RESTRICTION ON ACQUISITION OF NOTES
BY THE COMPANY AND ITS AFFILIATES. 

The Company will promptly deliver to the Trustee for cancellation all Notes that the Company or any of its Subsidiaries have

Section 3.09. FURTHER INSTRUMENTS AND ACTS. 

At the Trustee’s request, the Company will execute and deliver such further instruments and do such further acts as may be
reasonably necessary or proper to more effectively carry out the purposes of this Indenture. 
 Article 4. REPURCHASE AND REDEMPTION

 Section 4.01. NO SINKING FUND. 

No sinking fund is required to be provided for the Notes. 

Section 4.02. RIGHT OF HOLDERS TO REQUIRE
THE COMPANY TO REPURCHASE NOTES UPON A FUNDAMENTAL CHANGE. 

(A) Right of Holders to Require the Company to Repurchase Notes Upon a Fundamental Change. Subject to the other terms of
this Section 4.02, if a Fundamental Change 

  
 - 30 - 

 
occurs, then each Holder will have the right (the “Fundamental Change Repurchase Right”) to require the Company to repurchase such Holder’s Notes (or any portion thereof in
an Authorized Denomination) on the Fundamental Change Repurchase Date for such Fundamental Change for a cash purchase price equal to the Fundamental Change Repurchase Price. 

(B) Repurchase Prohibited in Certain Circumstances. If the principal amount of the Notes has been accelerated and such
acceleration has not been rescinded on or before the Fundamental Change Repurchase Date for a Repurchase Upon Fundamental Change (including as a result of the payment of the related Fundamental Change Repurchase Price, and any related interest
pursuant to the proviso to Section 4.02(D), on such Fundamental Change Repurchase Date), then (i) the Company may not repurchase any Notes pursuant to this Section 4.02; and (ii) the Company will cause any
Notes theretofore surrendered for such Repurchase upon Fundamental Change to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer to the Company, the Trustee or the
Paying Agent of the applicable beneficial interest in such Notes in accordance with the Depositary Procedures). 
 (C)
Fundamental Change Repurchase Date. The Fundamental Change Repurchase Date for any Fundamental Change will be a Business Day of the Company’s choosing that is no more than thirty five (35), nor less than twenty (20), Business Days after
the date the Company sends the related Fundamental Change Notice pursuant to Section 4.02(E). 
 (D) Fundamental
Change Repurchase Price. The Fundamental Change Repurchase Price for any Note to be repurchased upon a Repurchase Upon Fundamental Change following a Fundamental Change is an amount in cash equal to the principal amount of such Note plus accrued
and unpaid interest on such Note to, but excluding, the Fundamental Change Repurchase Date for such Fundamental Change; provided, however, that if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before
the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Repurchase Upon Fundamental Change, to receive, on or before such Interest Payment
Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Fundamental Change
Repurchase Date is before such Interest Payment Date); and (ii) the Fundamental Change Repurchase Price will not include accrued and unpaid interest on such Note to, but excluding, such Fundamental Change Repurchase Date. For the avoidance of
doubt, if an Interest Payment Date is not a Business Day within the meaning of Section 2.05(C) and such Fundamental Change Repurchase Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and
unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance with Section 2.05(C), on the next Business Day to Holders at of the Close of Business on the immediately preceding Regular Record Date; and
(y) the Fundamental Change Repurchase Price will include interest on Notes to be repurchased from, and including, such Interest Payment Date. 

(E) Fundamental Change Notice. On or before the twentieth (20th) calendar day after the occurrence of a Fundamental
Change, the Company will send to each Holder (and to any beneficial owner of a Global Note, if required by applicable law), the Trustee and the Paying 

  
 - 31 - 

 
Agent a notice of such Fundamental Change (a “Fundamental Change Notice”). 

Such Fundamental Change Notice must state: 

(i) briefly, the events causing such Fundamental Change; 

(ii) the effective date of such Fundamental Change; 

(iii) the procedures that a Holder must follow to require the Company to repurchase its Notes pursuant to this
Section 4.02, including the deadline for exercising the Fundamental Change Repurchase Right and the procedures for submitting and withdrawing a Fundamental Change Repurchase Notice; 

(iv) the Fundamental Change Repurchase Date for such Fundamental Change; 

(v) the Fundamental Change Repurchase Price per $1,000 principal amount of Notes for such Fundamental Change
(and, if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso to Section 4.02(D)); 

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

(vii) the Conversion Rate in effect on the date of such Fundamental Change Notice and a description and
quantification of any adjustments to the Conversion Rate that may result from such Fundamental Change (including pursuant to Section 5.07); 

(viii) that Notes for which a Fundamental Change Repurchase Notice has been duly tendered and not duly
withdrawn must be delivered to the Paying Agent for the Holder thereof to be entitled to receive the Fundamental Change Repurchase Price; 

(ix) that Notes (or any portion thereof) that are subject to a Fundamental Change Repurchase Notice that has
been duly tendered may be converted only if such Fundamental Change Repurchase Notice is withdrawn in accordance with this Indenture; and 

(x) the CUSIP and ISIN numbers, if any, of the Notes. 

Neither the failure to deliver a Fundamental Change Notice nor any defect in a Fundamental Change Notice will limit the
Fundamental Change Repurchase Right of any Holder or otherwise affect the validity of any proceedings relating to any Repurchase Upon Fundamental Change. 

(F) Procedures to Exercise the Fundamental Change Repurchase Right. 

  
 - 32 - 

 (i) Delivery of Fundamental Change Repurchase Notice and Notes
to Be Repurchased. To exercise its Fundamental Change Repurchase Right for a Note following a Fundamental Change, the Holder thereof must deliver to the Paying Agent: 

(1) before the Close of Business on the Business Day immediately before the related Fundamental Change
Repurchase Date (or such later time as may be required by law), a duly completed, written Fundamental Change Repurchase Notice with respect to such Note; and 

(2) such Note, duly endorsed for transfer (if such Note is a Physical Note) or by book-entry transfer (if such
Note is a Global Note). 
 The Paying Agent will promptly deliver to the Company a copy of each Fundamental Change Repurchase
Notice that it receives. 
 (ii) Contents of Fundamental Change Repurchase Notices. Each Fundamental
Change Repurchase Notice with respect to a Note must state: 
 (1) if such Note is a Physical Note, the
certificate number of such Note; 
 (2) the principal amount of such Note to be repurchased, which must be an
Authorized Denomination; and 
 (3) that such Holder is exercising its Fundamental Change Repurchase Right
with respect to such principal amount of such Note; 
 provided, however, that if such Note is a Global Note,
then such Fundamental Change Repurchase Notice must comply with the Depositary Procedures (and any such Fundamental Change Repurchase Notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this
Section 4.02(F)). 
 (iii) Withdrawal of Fundamental Change Repurchase Notice. A Holder that
has delivered a Fundamental Change Repurchase Notice with respect to Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent at any time before the Close of Business on the
Business Day immediately before the related Fundamental Change Repurchase Date. Such withdrawal notice must state: 

(1) if such Note is a Physical Note, the certificate number of such Note; 

(2) the principal amount of such Note to be withdrawn, which must be an Authorized Denomination; and 

(3) the principal amount of such Note, if any, that remains subject to such Fundamental Change Repurchase
Notice, which must be an Authorized Denomination; 

  
 - 33 - 

 provided, however, that if such Note is a Global Note, then such
withdrawal notice must comply with the Depositary Procedures (and any such withdrawal notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)). 

Upon receipt of any such withdrawal notice with respect to a Note (or any portion thereof), the Paying Agent will
(x) promptly deliver a copy of such withdrawal notice to the Company; and (y) if such Note is surrendered to the Paying Agent, cause such Note (or such portion thereof in accordance with Section 2.11, treating
such Note as having been then surrendered for partial repurchase in the amount set forth in such withdrawal notice as remaining subject to repurchase) to be returned to the Holder thereof (or, if applicable with respect to any Global Note, cancel
any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Note in accordance with the Depositary Procedures). 

(G) Payment of the Fundamental Change Repurchase Price. Without limiting the Company’s obligation to deposit the
Fundamental Change Repurchase Price within the time proscribed by Section 3.01(B), the Company will cause the Fundamental Change Repurchase Price for a Note (or portion thereof) to be repurchased pursuant to a Repurchase Upon Fundamental
Change to be paid to the Holder thereof on or before the later of (i) the applicable Fundamental Change Repurchase Date; and (ii) the date (x) such Note is delivered to the Paying Agent (in the case of a Physical Note) or (y) the
Depositary Procedures relating to the repurchase, and the delivery to the Paying Agent, of such Holder’s beneficial interest in such Note to be redeemed are complied with (in the case of a Global Note). For the avoidance of doubt, interest
payable pursuant to the proviso to Section 4.02(D) on any Note to be repurchased pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to such proviso regardless of whether such Note is delivered or such Depositary Procedures
are complied with pursuant to the first sentence of this Section 4.02(G). 
 (H) Third Party May Conduct
Repurchase Offer In Lieu of the Company. Notwithstanding anything to the contrary in this Section 4.02, the Company will be deemed to satisfy its obligations under this Section 4.02 if
(i) one or more third parties conduct any Repurchase Upon Fundamental Change and related offer to repurchase Notes otherwise required by this Section 4.02 in a manner that would have satisfied the requirements of this
Section 4.02 if conducted directly by the Company and (ii) an owner of a beneficial interest in the Notes would not receive a lesser amount (as a result of taxes, additional expenses or for any other reason) than such
owner would have received had the Company repurchased the notes. 
 (I) No Requirement to Conduct an Offer to Repurchase
Notes if the Fundamental Change Results in the Notes Becoming Convertible into an Amount of Cash Exceeding the Fundamental Change Repurchase Price. Notwithstanding anything to the contrary in this Section 4.02, the
Company will not be required to send a Fundamental Change Notice pursuant to Section 4.02(E), or offer to repurchase or repurchase any Notes pursuant to this Section 4.02, in connection with a Fundamental Change
occurring pursuant to clause (B)(ii) (or pursuant to clause (A) that also constitutes a Fundamental Change occurring pursuant to clause (B)(ii)) of the definition thereof, if (i) such Fundamental Change constitutes a Common Stock Change
Event for which all or part of the Reference Property consists of cash in U.S. dollars; (ii) immediately 

  
 - 34 - 

 
after such Fundamental Change, the Notes become convertible, pursuant to Section 5.09(A) and, if applicable, Section 5.07, into consideration that includes such
cash in an amount per $1,000 aggregate principal amount of Notes that equals or exceeds the Fundamental Change Repurchase Price per $1,000 aggregate principal amount of Notes (calculated assuming that the same includes accrued interest to, but
excluding, the latest possible Fundamental Change Repurchase Date for such Fundamental Change); and (iii) the Company timely sends the notice relating to such Fundamental Change required pursuant to Section 5.01(C)(i)(3)(b). 

(J) Compliance with Applicable Securities Laws. The Company will comply with all federal and state securities laws in
connection with a Repurchase Upon Fundamental Change (including complying with Rules 13e-4 and 14e-1 under the Exchange Act and filing any required Schedule TO, to the
extent applicable) so as to permit effecting such Repurchase Upon Fundamental Change in the manner set forth in this Indenture. However, to the extent that the provisions of any securities laws or regulations adopted after the date on which the
Notes are first issued conflict with the provisions of this Indenture relating to the Company’s obligations to effect a Repurchase Upon Fundamental Change, the Company will comply with such applicable securities laws and regulations and will
not be deemed to have breached its obligations under such provisions of this Indenture by virtue of such conflict. 
 (K)
Repurchase in Part. Subject to the terms of this Section 4.02, Notes may be repurchased pursuant to a Repurchase Upon Fundamental Change in part, but only in Authorized Denominations. Provisions of this
Section 4.02 applying to the repurchase of a Note in whole will equally apply to the repurchase of a permitted portion of a Note. 

Section 4.03. RIGHT OF THE COMPANY TO REDEEM
THE NOTES. 
 (A) No Right to Redeem Before May 15, 2021. The
Company may not redeem the Notes at its option at any time before May 15, 2021. 
 (B) Right to Redeem the Notes on
or After May 15, 2021. Subject to the terms of this Section 4.03, the Company has the right, at its election, to redeem all, or any portion in an Authorized Denomination, of the Notes, at any time and
from time to time, on a Redemption Date on or after May 15, 2021, for a cash purchase price equal to the Redemption Price, but only if the Last Reported Sale Price per share of Common Stock exceeds one hundred and thirty percent (130%) of the
Conversion Price on each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the Trading Day immediately before the Redemption Notice Date for such
Redemption. 
 (C) Redemption Prohibited in Certain Circumstances. If the principal amount of the Notes has been
accelerated (other than as a result of a failure to make the payment of the related Redemption Price, and any related interest pursuant to the proviso to Section 4.03(E), on such Redemption Date) and such acceleration has not been rescinded
on or before the Redemption Date, then (i) the Company may not call for Redemption or otherwise redeem any Notes pursuant to this Section 4.03; and (ii) the Company will cause any Notes theretofore surrendered for
such Redemption to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interests in such
Notes in accordance with the 

  
 - 35 - 

 
Depositary Procedures). 
 (D) Redemption Date. The Redemption
Date for any Redemption will be a Business Day of the Company’s choosing that is no more than fifty-five (55), nor less than thirty-five (35), Scheduled Trading Days after the Redemption Notice Date for such Redemption. 

(E) Redemption Price. The Redemption Price for any Note called for Redemption is an amount in cash equal to the
principal amount of such Note plus accrued and unpaid interest on such Note to, but excluding, the Redemption Date for such Redemption; provided, however, that if such Redemption Date is after a Regular Record Date and on or before the
next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Redemption, to receive, on or before such Interest Payment Date, the unpaid interest that
would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Redemption Date is before such Interest Payment
Date); and (ii) the Redemption Price will not include accrued and unpaid interest on such Note to, but excluding, such Redemption Date. For the avoidance of doubt, if an Interest Payment Date is not a Business Day within the meaning of
Section 2.05(C) and such Redemption Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance
with Section 2.05(C), on the next Business Day to Holders at of the Close of Business on the immediately preceding Regular Record Date; and (y) the Redemption Price will include interest on Notes to be redeemed from, and including, such
Interest Payment Date. 
 (F) Redemption Notice. To call any Notes for Redemption, the Company must send to each
Holder (and to any beneficial owner of a Global Note, if required by applicable law), the Trustee and the Paying Agent a written notice of such Redemption (a “Redemption Notice”). 

Such Redemption Notice must state: 

(i) that the Notes have been called for Redemption, briefly describing the Company’s Redemption right
under this Indenture; 
 (ii) the Redemption Date for such Redemption; 

(iii) the Redemption Price per $1,000 principal amount of Notes for such Redemption (and, if the Redemption
Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso to Section 4.03(E)); 

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

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

(vi) the Conversion Rate in effect on the Redemption Notice Date for such 

  
 - 36 - 

 
Redemption; 
 (vii) the Settlement Method that will
apply to all conversions of Notes with a Conversion Date that occurs on or after such Redemption Notice Date and before such Redemption Date; 

(viii) that Notes called for Redemption must be delivered to the Paying Agent (in the case of Physical Notes)
or the Depositary Procedures must be complied with (in the case of Global Notes) for the Holder thereof to be entitled to receive the Redemption Price; and 

(ix) the CUSIP and ISIN numbers, if any, of the Notes. 

On or before the Redemption Notice Date, the Company will send a copy of such Redemption Notice to the Trustee and the Paying
Agent. 
 (G) If less than all Notes then outstanding are called for Redemption, then: 

(i) the Notes to be redeemed will be selected by the Trustee as follows: (1) in the case of Global Notes,
in accordance with the Depositary Procedures; and (2) in the case of Physical Notes, pro rata, by lot; and 

(ii) if only a portion of a Note is subject to Redemption and such Note is converted in part, then the
converted portion of such Note will be deemed to be from the portion of such Note that was subject to Redemption. 
 (H)
Payment of the Redemption Price. Without limiting the Company’s obligation to deposit the Redemption Price by the time proscribed by Section 3.01(B), the Company will cause the Redemption Price for a Note (or portion thereof)
subject to Redemption to be paid to the Holder thereof on or before the later of (i) the applicable Redemption Date; and (ii) the date (x) such Note is delivered to the Paying Agent (in the case of a Physical Note) or (y) the
Depositary Procedures relating to the Redemption, and the delivery to the Paying Agent, of such Holder’s beneficial interest in such Note to be redeemed are complied with (in the case of a Global Note). For the avoidance of doubt, interest
payable pursuant to the proviso to Section 4.03(E) on any Note (or portion thereof) subject to Redemption must be paid pursuant to such proviso regardless of whether such Note is delivered or such Depositary Procedures are complied with
pursuant to the first sentence of this Section 4.03(H). 
 Article 5. CONVERSION 

Section 5.01. RIGHT TO CONVERT. 

(A) Generally. Subject to the provisions of this Article 5, each Holder may, at its option, convert such
Holder’s Notes into Conversion Consideration. 
 (B) Conversions in Part. Subject to the terms of this
Indenture, Notes may be converted in part, but only in Authorized Denominations. Provisions of this Article 5 applying to the conversion of a Note in whole will equally apply to conversions of a permitted portion of a

  
 - 37 - 

 
Note. 
 (C) When Notes May Be Converted. 

(i) Generally. Subject to Section 5.01(C)(ii), a Note may be converted only in the following
circumstances: 
 (1) Conversion upon Satisfaction of Common Stock Sale Price Condition. Prior to the
Close of Business on the Business Day immediately preceding January 15, 2024, a Holder may convert its Notes during any calendar quarter commencing after the calendar quarter ending on September 30, 2017 (and only during such calendar
quarter), if the Last Reported Sale Price per share of Common Stock for each of at least twenty (20) Trading Days (whether or not consecutive) during the period of thirty (30) consecutive Trading Days ending on, and including, the last
Trading Day of the immediately preceding calendar quarter exceeds one hundred and thirty percent (130%) of the Conversion Price on the applicable Trading Day. 

(2) Conversion upon Satisfaction of Note Trading Price Condition. Prior to the Close of Business on the
Business Day immediately preceding January 15, 2024, a Holder may convert its Notes during the five (5) consecutive Business Days immediately after any ten (10) consecutive Trading Day period (such ten (10) consecutive Trading
Day period, the “Measurement Period”) if the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder in accordance with the procedures set forth below, for each Trading Day of the
Measurement Period was less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. The condition set forth in the preceding sentence
is referred to in this Indenture as the “Trading Price Condition.” 
 The Trading Price will be determined
by the Bid Solicitation Agent pursuant to this Section 5.01(C)(i)(2) and the definition of “Trading Price.” The Bid Solicitation Agent (if not the Company) will have no obligation to determine the Trading Price of the Notes unless
the Company has requested such determination in writing, and the Company will have no obligation to make such request (or seek bids itself) unless a Holder of at least five million dollars ($5,000,000) aggregate principal amount of Notes (or such
lesser principal amount as may be then outstanding) provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than ninety eight percent (98%) of the product of the Last Reported Sale
Price per share of Common Stock and the Conversion Rate. If such a Holder provides such evidence, then the Company will (if acting as Bid Solicitation Agent), or will instruct the Bid Solicitation Agent to, determine the Trading Price of the Notes
beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per

  
 - 38 - 

 
share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. If the Trading Price Condition has been met as set forth above, then the Company will notify the Holders,
the Trustee and the Conversion Agent of the same, and each of the Holders, the Trustee and the Conversion Agent will be entitled to rely conclusively upon the accuracy of such notice and any calculations therein without independent verification. If,
on any Trading Day after the Trading Price Condition has been met as set forth above, the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per
share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day, then the Company will notify the Holders, the Trustee and the Conversion Agent of the same, and, thereafter, neither the Company nor the Bid Solicitation Agent
will be required to solicit bids again until another Holder request is made as provided above. 
 (3) Conversion upon
Specified Corporate Events. 
 (a) Certain Distributions. If the Company elects to: 

(I) distribute, to all or substantially all holders of Common Stock, any rights, options or warrants (other
than rights issued pursuant to a stockholder rights plan, so long as such rights have not separated from the Common Stock and are not exercisable until the occurrence of a triggering event, except that such rights will be deemed to be distributed
under this clause (I) upon their separation from the Common Stock or upon the occurrence of such triggering event) entitling them, for a period of not more than sixty (60) calendar days after the record date of such distribution, to
subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day
immediately before the date such distribution is announced; or 
 (II) distribute, to all or substantially
all holders of Common Stock, assets or securities of the Company or rights to purchase the Company’s securities, which distribution per share of Common Stock has a value, as reasonably determined by the Company in good faith, exceeding ten
percent (10%) of the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before the date such distribution is announced, 

then, in either case, (x) the Company will send notice of such distribution, and of the related right to convert Notes,
to Holders, the Trustee and the Conversion Agent at least thirty-five (35) Scheduled Trading Days before the Ex-Dividend Date for such distribution (or, if later in the case of any such separation of
rights issued pursuant to a stockholder rights plan or the occurrence of any such triggering event under a stockholder rights plan, as 

  
 - 39 - 

 
soon as reasonably practicable after the Company becomes aware of that such separation or triggering event has occurred or will occur); and (y) once the Company has sent such notice, Holders
may convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately before such Ex-Dividend Date and the Company’s announcement that such distribution will not
take place. 
 (b) Certain Corporate Events. If, prior to the Close of Business on the Business Day
immediately preceding January 15, 2024, a Fundamental Change, Make-Whole Fundamental Change or Common Stock Change Event occurs, then, in each case, Holders may convert their Notes at any time from, and including, the effective date of such
transaction or event to, and including, the thirty fifth (35th) Trading Day after such effective date (or, if such transaction or event also constitutes a Fundamental Change (other than an Exempted Fundamental Change), to, but excluding, the related
Fundamental Change Repurchase Date). No later than the second (2nd) Business Day after the effective date of any Fundamental Change, Make-Whole Fundamental Change or Common Stock Change Event that occurs before the Maturity Date, the Company will
send notice to the Holders, the Trustee and the Conversion Agent of such transaction or event, such effective date and, if applicable, the related right to convert Notes. 

(4) Conversion upon Redemption. If the Company calls any Note for Redemption, then the Holder of such
Note may convert such Note at any time before the Close of Business on the Business Day immediately before the related Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such
time as the Company pays such Redemption Price in full). 
 (5) Conversions During Free Convertibility
Period. A Holder may convert its Notes at any time from, and including, January 15, 2024 until the Close of Business on the Scheduled Trading Day immediately before the Maturity Date. 

For the avoidance of doubt, the Notes may become convertible pursuant to any one or more of the preceding sub-paragraphs of this Section 5.01(C)(i) and the Notes ceasing to be convertible pursuant to a particular sub-paragraph of this Section 5.01(C)(i) will not
preclude the Notes from being convertible pursuant to any other sub-paragraph of this Section 5.01(C)(i). 

(ii) Limitations and Closed Periods. Notwithstanding anything to the contrary in this Indenture or the Notes: 

(1) Notes may be surrendered for conversion only after the Open of Business and before the Close of Business on
a day that is a Business Day; 

  
 - 40 - 

 (2) in no event may any Note be surrendered for conversion after
the Close of Business on the Scheduled Trading Day immediately before the Maturity Date; 
 (3) if the
Company calls any Note for Redemption pursuant to Section 4.03, then the Holder of such Note may not surrender such Note for conversion after the Close of Business on the Business Day immediately before the applicable
Redemption Date, except to the extent the Company fails to pay the Redemption Price for such Note in accordance with this Indenture; and 

(4) if a Fundamental Change Repurchase Notice is validly delivered pursuant to Section 4.02(F) with
respect to any Note, then such Note may not be converted, except to the extent (a) such Note is not subject to such notice; (b) such notice is withdrawn in accordance with Section 4.02(F); or (c) the Company fails to pay the
Fundamental Change Repurchase Price for such Note in accordance with this Indenture. 
 Section 5.02. CONVERSION
PROCEDURES. 
 (A) Generally. 

(i) Global Notes. To convert a beneficial interest in a Global Note that is convertible pursuant to
Section 5.01(C), the owner of such beneficial interest must (1) comply with the Depositary Procedures for converting such beneficial interest (at which time such conversion will become irrevocable); and (2) pay any amounts due
pursuant to Section 5.02(D) or Section 5.02(E). 
 (ii) Physical Notes. To convert all
or a portion of a Physical Note that is convertible pursuant to Section 5.01(C), the Holder of such Note must (1) complete, manually sign and deliver to the Conversion Agent the conversion notice attached to such Physical Note or a
facsimile of such conversion notice; (2) deliver such Physical Note to the Conversion Agent (at which time such conversion will become irrevocable); (3) furnish any endorsements and transfer documents that the Company or the Conversion Agent
may require; and (4) pay any amounts due pursuant to Section 5.02(D) or Section 5.02(E). 
 (B) Effect
of Converting a Note. At the Close of Business on the Conversion Date for a Note (or any portion thereof), such Note (or such portion thereof) will be deemed to cease to be outstanding (and, for the avoidance of doubt, no Person will be deemed
to be a Holder of such Note (or such portion thereof) as of the Close of Business on such Conversion Date), except to the extent provided in Section 5.02(D). 

(C) Holder of Record of Conversion Shares. The Person in whose name any share of Common Stock is issuable upon
conversion of any Note will be deemed to become the holder of record of such share as of the Close of Business on (i) the Conversion Date for such conversion, in the case of Physical Settlement; or (ii) the last VWAP Trading Day of the
Observation Period for such conversion, in the case of Combination Settlement. 

  
 - 41 - 

 (D) Interest Payable upon Conversion in Certain Circumstances. If the
Conversion Date of a Note is after a Regular Record Date and before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such conversion (and,
for the avoidance of doubt, notwithstanding anything set forth in the proviso to this sentence), to receive, on or before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment
Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date); and (ii) the Holder surrendering such Note for conversion must deliver to the Conversion Agent, at the time of such surrender,
an amount of cash equal to the amount of such interest referred to in clause (i) above; provided, however, that the Holder surrendering such Note for conversion need not deliver such cash (w) if the Company has specified a
Redemption Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment Date; (x) if such Conversion Date occurs after the Regular Record Date immediately before the Maturity Date;
(y) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment Date; or (z) to the extent of any overdue interest or
interest that has accrued on any overdue interest. For the avoidance of doubt, as a result of, and without limiting the generality of, the foregoing, if a Note is converted with a Conversion Date that is after the Regular Record Date immediately
before the Maturity Date, then the Company will pay, as provided above, the interest that would have accrued on such Note to, but excluding, the Maturity Date. For the avoidance of doubt, if the Conversion Date of a Note to be converted is on an
Interest Payment Date, then the Holder of such Note at the Close of Business on the Regular Record Date immediately before such Interest Payment Date will be entitled to receive, on such Interest Payment Date, the unpaid interest that has accrued on
such Note to, but excluding, such Interest Payment Date, and such Note, when surrendered for conversion, need not be accompanied by any cash amount pursuant to the first sentence of this Section 5.02(D). 

(E) Taxes and Duties. If a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or
transfer tax or duty due on the issue of any shares of Common Stock upon such conversion; provided, however, that if any tax or duty is due because such Holder requested such shares to be issued in a name other than such Holder’s
name, then such Holder will pay such tax or duty and, until having received a sum sufficient to pay such tax or duty, the Conversion Agent may refuse to deliver any such shares to be issued in a name other than that of such Holder. 

(F) Conversion Agent to Notify Company of Conversions. If any Note is submitted for conversion to the Conversion Agent
or the Conversion Agent receives any notice of conversion with respect to a Note, then the Conversion Agent will promptly notify the Company and the Trustee (if other than the Conversion Agent) of such occurrence, together with any other information
reasonably requested by the Company, and will cooperate with the Company to determine the Conversion Date for such Note. 
 Section 5.03.
SETTLEMENT UPON CONVERSION. 
 (A) Settlement Method. Upon the
conversion of any Note, the Company will settle such conversion by paying or delivering, as applicable and as provided in this Article 5, either (x) shares of Common Stock, together, if applicable, with cash in lieu of fractional shares
as 

  
 - 42 - 

 
provided in Section 5.03(B)(i)(1) (a “Physical Settlement”); (y) solely cash as provided in Section 5.03(B)(i)(2) (a “Cash Settlement”); or
(z) a combination of cash and shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 5.03(B)(i)(3) (a “Combination Settlement”). 

The Company will have the right to elect the Settlement Method applicable to any conversion of a Note; provided,
however, that: 
 (i) subject to clause (iii) below, all conversions of Notes with a
Conversion Date that occurs on or after January 15, 2024 will be settled using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders and the Conversion Agent no later than the Close of Business on the
Scheduled Trading Day immediately before January 15, 2024; 
 (ii) subject to clause
(iii) below, if the Company elects a Settlement Method with respect to the conversion of any Note whose Conversion Date occurs before January 15, 2024, then the Company will send notice of such Settlement Method to the Holder of such
Note and the Conversion Agent no later than the Close of Business on the second (2nd) Business Day immediately after such Conversion Date (or, if the T+2 Effective Date has occurred by such Conversion Date, no later than the Close of Business on the
Business Day immediately after such Conversion Date); 
 (iii) if any Notes are called for Redemption, then
(1) the Company will specify, in the related Redemption Notice sent pursuant to Section 4.03(F), the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the related Redemption
Notice Date and before the Business Day immediately before the related Redemption Date; and (2) if such Redemption Date occurs on or after January 15, 2024, then such Settlement Method must be the same Settlement Method that, pursuant to
clause (i) above, applies to all conversions of Notes with a Conversion Date that occurs on or after January 15, 2024; 

(iv) the Company will use the same Settlement Method for all conversions of Notes with a Conversion Date that
occurs on the same day (and, for the avoidance of doubt, the Company will not be obligated to use the same Settlement Method with respect to conversions of Notes whose Conversion Dates occur on different days, except as provided in clause
(i) or (iii) above); 
 (v) if the Company does not timely elect a Settlement Method with
respect to the conversion of a Note, then the Company will be deemed to have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not constitute a Default or Event of Default); 

(vi) if the Company timely elects Combination Settlement with respect to the conversion of a Note but does not
timely notify the Holder of such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of Notes (and, for the avoidance of doubt, the failure to
timely send such notification will not constitute a Default or Event of 

  
 - 43 - 

 
Default); and 
 (vii) the Settlement Method will be
subject to Section 5.09(A)(2) 
 (B) Conversion Consideration. 

(i) Generally. Subject to Section 5.03(B)(ii) and Section 5.03(B)(iii), the type and
amount of consideration (the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be converted will be as follows: 

(1) if Physical Settlement applies to such conversion, subject to Section 5.03(B)(ii), a number of
shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion; 

(2) if Cash Settlement applies to such conversion, cash in an amount equal to the sum of the Daily Conversion
Values for each VWAP Trading Day in the Observation Period for such conversion; or 
 (3) if Combination
Settlement applies to such conversion, consideration consisting, subject to Section 5.03(B)(ii), of (a) a number of shares of Common Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period
for such conversion; and (b) an amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation Period. 

(ii) Cash in Lieu of Fractional Shares. If Physical Settlement or Combination Settlement applies to the
conversion of any Note and the number of shares of Common Stock deliverable pursuant to Section 5.03(B)(i) upon such conversion is not a whole number, then such number will be rounded down to the nearest whole number and the Company will
deliver, in addition to the other consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such fraction and (2) (x) the Daily VWAP on the Conversion Date for such conversion
(or, if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day), in the case of Physical Settlement; or (y) the Daily VWAP on the last VWAP Trading Day of the Observation Period for such conversion, in the
case of Combination Settlement. 
 (iii) Conversion of Multiple Notes by a Single Holder. If a Holder
converts more than one (1) Note on a single Conversion Date, then the Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and practicable under, the Depositary Procedures)
be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder. 

(iv) Notice of Calculation of Conversion Consideration. If Cash Settlement or Combination Settlement
applies to the conversion of any Note, then the Company will determine the Conversion Consideration due thereupon promptly following the last VWAP Trading Day of the applicable Observation Period and will promptly thereafter send notice to the
Trustee and the Conversion Agent of the same and the calculation 

  
 - 44 - 

 
thereof in reasonable detail. Neither the Trustee nor the Conversion Agent will have any duty to make any such determination. 

(C) Delivery of the Conversion Consideration. Except as set forth in Sections 5.05(A), 5.05(D) and
5.09 Company will pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder as follows: (i) if Cash Settlement or Combination Settlement applies to such conversion, on or before the
third (3rd) (or, if the T+2 Effective Date has occurred by the last VWAP Trading Day of the Observation Period for such conversion, the second (2nd)) Business Day immediately after the last VWAP Trading Day of such Observation Period; and
(ii) if Physical Settlement applies to such conversion, on or before the third (3rd) (or, if the T+2 Effective Date has occurred by the Conversion Date for such conversion, the second (2nd)) Business Day immediately after such Conversion Date.

 (D) Deemed Payment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion. If a
Holder converts a Note, then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and, except as provided in Section 5.02(D), the Company’s delivery of the Conversion Consideration
due in respect of such conversion will be deemed to fully satisfy and discharge the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note. As a result, except as provided in Section 5.02(D),
any accrued and unpaid interest on a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, subject to Section 5.02(D), if the Conversion Consideration for a Note consists of both cash
and shares of the Common Stock, then accrued and unpaid interest that is deemed to be paid therewith will be deemed to be paid first out of such cash. 

Section 5.04. RESERVE AND STATUS OF COMMON
STOCK ISSUED UPON CONVERSION. 
 (A) Stock Reserve.
At all times when any Notes are outstanding, the Company will reserve, out of its authorized but unissued and unreserved shares of Common Stock, a number of shares of Common Stock sufficient to permit the conversion of all then-outstanding Notes,
assuming (x) Physical Settlement will apply to such conversion; and (y) the Conversion Rate is increased by the maximum amount pursuant to which the Conversion Rate may be increased pursuant to Section 5.07. 

(B) Status of Conversion Shares; Listing. Each Conversion Share, if any, delivered upon conversion of any Note will be
duly and validly issued, fully paid, non-assessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of
the Holder of such Note or the Person to whom such Conversion Share will be delivered). If the Common Stock is then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will cause each Conversion Share,
when delivered upon conversion of any Note, to be admitted for listing on such exchange or quotation on such system. 

Section 5.05. ADJUSTMENTS TO THE CONVERSION RATE. 

(A) Events Requiring an Adjustment to the Conversion Rate. The Conversion Rate

  
 - 45 - 

 
will be adjusted from time to time as follows: 
 (i)
Stock Dividends, Splits and Combinations. If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination
of the Common Stock (in each case excluding an issuance solely pursuant to a Common Stock Change Event, as to which the provisions set forth in Section 5.09 will apply), then the Conversion Rate will be adjusted based on
the following formula: 
  

											
	CR1 	 	=	 	CR0	 	x	 	OS1	 	
	 	 	 	 	OS0	 	

  

					
	where:	 		  	
			
	CR0	 	=	  	 the Conversion Rate in effect immediately before the Open of Business on the
Ex-Dividend Date for such dividend or distribution, or immediately before the Open of Business on the effective date of such stock split or stock combination, as applicable;

			
	CR1	 	=	  	 the Conversion Rate in effect immediately after the Open of Business on such
Ex-Dividend Date or the Open of Business on such effective date, as applicable;

			
	OS0	 	=	  	 the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date or effective date, as applicable, without giving effect to such dividend, distribution, stock split or stock combination; and

			
	OS1	 	=	  	 the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock
split or stock combination.

 If any dividend, distribution, stock split or stock combination of the type described in
this Section 5.05(A)(i) is declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such
stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been declared or announced. 

(ii) Rights, Options and Warrants. If the Company distributes, to all or substantially all holders of
Common Stock, rights, options or warrants (other than rights issued pursuant to a stockholder rights plan, to which the provisions set forth in Sections 5.05(A)(iii)(1) and 5.05(F) will apply) entitling such holders, for a period of
not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the 

  
 - 46 - 

 
Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is
announced, then the Conversion Rate will be increased based on the following formula: 
  

											
	CR1 	 	=	 	CR0	 	x	 	OS+X	 	
	 	 	 	 	OS+Y	 	

  

					
	where:	 		  	
			
	CR0	 	=	  	 the Conversion Rate in effect immediately before the Open of Business on the
Ex-Dividend Date for such distribution;

			
	CR1	 	=	  	 the Conversion Rate in effect immediately after the Open of Business on such
Ex-Dividend Date;

			
	OS	 	=	  	 the number of shares of Common Stock outstanding immediately before 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
	 	=	  	 a number of shares of Common Stock obtained by dividing (x) the aggregate price payable to exercise such rights,
options or warrants by (y) the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is
announced.

 To the extent that shares of Common Stock are not delivered after the expiration of such
rights, options or warrants (including as a result of such rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such
distribution been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, option or warrants. To the extent such rights, options or warrants are not so distributed, the Conversion
Rate will be readjusted to the Conversion Rate that would then be in effect had the Ex-Dividend Date for the distribution of such rights, options or warrants not occurred. 

For purposes of this Section 5.05(A)(ii) and Section 5.01(C)(i)(3)(a), in determining whether any rights, options
or warrants entitle holders of Common Stock to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading
Days ending on, and including, the Trading Day immediately before the date of the distribution of such rights, options or warrants is announced, and in determining the aggregate price payable to exercise such rights, options or warrants, there will
be taken into account any consideration the Company receives for such rights, options or warrants 

  
 - 47 - 

 
and any amount payable on exercise thereof, with the value of such consideration, if not cash, to be determined by the Company in good faith. 

(iii) Spin-Offs and Other Distributed Property. 

(1) Distributions Other than Spin-Offs. If the Company distributes shares of its Capital Stock,
evidences of its indebtedness or other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common Stock, excluding: 

(v) dividends, distributions, rights, options or warrants for which an adjustment to the Conversion Rate is
required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(i) or 5.05(A)(ii); 

(w) dividends or distributions paid exclusively in cash for which an adjustment to the Conversion Rate is
required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iv); 

(x) rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent
provided in Section 5.05(F); 
 (y) Spin-Offs for which an adjustment to the Conversion Rate is
required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iii)(2); and 

(z) a distribution solely pursuant to a Common Stock Change Event, as to which the provisions set forth in
Section 5.09 will apply, 
 then the Conversion Rate will be increased based on the following
formula: 
  

											
	CR1 	 	=	 	CR0	 	x	 	     SP	 	
	 	 	 	 	SP – FMV	 	

  

					
	where:	 		  	
			
	CR0	 	=	  	 the Conversion Rate in effect immediately before the Open of Business on the
Ex-Dividend Date for such distribution;

			
	CR1	 	=	  	 the Conversion Rate in effect immediately after the Open of Business on such
Ex-Dividend Date;

			
	SP	 	=	  	 the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days
ending on, and including, the Trading Day immediately before such Ex-Dividend

  
 - 48 - 

					
		 		  	 Date; and

			
	FMV	 	=	  	 the fair market value (as determined by the Company in good faith), as of such
Ex-Dividend Date, of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed per share of Common Stock pursuant to such distribution;

 provided, however, that if FMV is equal to or greater than
SP, then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at the same time and on the same terms as
holders of Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants that such Holder would have received if such Holder had owned, on such record date, a number of shares
of Common Stock equal to the Conversion Rate in effect on such record date. 
 To the extent such distribution is not so paid
or made, or such rights, options or warrants are not exercised before their expiration (including as a result of being redeemed or terminated), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the
adjustment been made on the basis of only the distribution, if any, actually made or paid or on the basis of the distribution of only such rights, options or warrants, if any, that were actually exercised, if at all. 

(2) Spin-Offs. If the Company distributes or dividends 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 to all or substantially all holders of the Common Stock (other than solely pursuant to a Common Stock Change Event, as to which the provisions set forth
in Section 5.09 will apply), and such Capital Stock or equity interest is listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), then the Conversion Rate will be increased based on the following formula: 
  

											
	CR1 	 	=	 	CR0	 	x	 	FMV+SP	 	
	 	 	 	 	      SP	 	

  

					
	where:	 		  	
			
	CR0	 	=	  	 the Conversion Rate in effect immediately before the Open of Business on the
Ex-Dividend Date for such Spin-Off;

			
	CR1	 	=	  	 the Conversion Rate in effect immediately after the Open of Business on such
Ex-Dividend Date;

  
 - 49 - 

					
	FMV	 	=	  	 the product of (x) the average of the Last Reported Sale Price per share or unit of the Capital Stock or equity
interests distributed in such Spin-Off over the ten (10) consecutive Trading Day period (the “Spin-Off Valuation Period”) beginning on, and
including, such Ex-Dividend Date (such average to be determined as if references to Common Stock in the definitions of Last Reported Sale Price and Trading Day were instead references such Capital Stock or
equity interests); and (y) the number of shares or units of such Capital Stock or equity interests distributed per share of Common Stock in such Spin-Off; and

			
	SP	 	=	  	 the average of the Last Reported Sale Prices per share of Common Stock over the
Spin-Off Valuation Period.

 The adjustment to the Conversion Rate pursuant to this Section 5.05(A)(iii)(2)
will be calculated as of the Close of Business on the last Trading Day of the Spin-Off Valuation Period but will be given effect immediately after the Open of Business on the
Ex-Dividend Date for the Spin-Off, with retroactive effect. If a Note is converted and the Conversion Date (in the case of Physical Settlement) or any VWAP Trading Day
of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the Spin-Off Valuation Period, then, notwithstanding anything to the contrary in this Indenture or
the Notes, the Company will, if necessary, delay the settlement of such conversion until the third (3rd) (or, if the T+2 Effective Date has occurred by the last day of the Spin-Off Valuation Period, the second
(2nd)) Business Day after the last day of the Spin-Off Valuation Period. 
 To the
extent any dividend or distribution of the type set forth in this Section 5.05(A)(iii)(2) is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been
made on the basis of only the dividend or distribution, if any, actually made or paid. 
 (iv) Cash
Dividends or Distributions. If any cash dividend or distribution is made to all or substantially all holders of Common Stock, then the Conversion Rate will be increased based on the following formula: 

 

											
	CR1 	 	=	 	CR0	 	x	 	    SP	 	
	 	 	 	 	SP – D	 	

  

					
	where:	 		  	
			
	CR0	 	=	  	 the Conversion Rate in effect immediately before the Open of Business on the
Ex-Dividend Date for such dividend or distribution;

			
	CR1	 	=	  	 the Conversion Rate in effect immediately after the Open of Business
on

  
 - 50 - 

					
		 		  	 such Ex-Dividend Date for such dividend or distribution;

			
	SP	 	=	  	 the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before such Ex-Dividend Date for such dividend or distribution;

			
	D	 	=	  	 the cash amount distributed per share of Common Stock in such dividend or distribution;

 provided, however, that if D is equal to or greater than SP,
then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution, at the same time and on the same terms as
holders of Common Stock, the amount of cash that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date. 

To the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will be readjusted to the
Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid. 

(v) Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries makes a payment in
respect of a tender offer or exchange offer for shares of Common Stock that is subject to the then-applicable tender offer rules under the Exchange Act (other than an odd-lot tender offer that satisfies the
requirements of Rule 13e-4(h)(5), or any successor rule), and the value (determined as of the Expiration Time by the Company) of the cash and other consideration paid per share of Common Stock in such tender
or exchange offer exceeds the average (such average, the “Reference Price”) of the Last Reported Sale Prices per share of Common Stock over the 10 consecutive Trading Day period (the “Tender/Exchange Offer Valuation
Period”) beginning on, and including, the Trading Day immediately after the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then
the Conversion Rate will be increased based on the following formula: 
  

											
	CR1 	 	=	 	CR0	 	x	 	AC+(SPx OS1)	 	
	 	 	 	 	      OS0 x SP	 	

  

					
	where:	 		  	
			
	CR0	 	=	  	 the Conversion Rate in effect immediately before the time (the “Expiration Time”) such tender or exchange
offer expires;

			
	CR1	 	=	  	 the Conversion Rate in effect immediately after the Expiration
Time;

  
 - 51 - 

					
	AC	 	=	  	 the aggregate value (determined as of the Expiration Time by the Company in good faith) of all cash and other consideration
paid or payable for shares of Common Stock purchased in such tender or exchange offer;

			
	OS0	 	=	  	 the number of shares of Common Stock outstanding immediately before the Expiration Time (before giving effect to the
purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

			
	OS1	 	=	  	 the number of shares of Common Stock outstanding immediately after the Expiration Time (excluding all shares of Common
Stock accepted for purchase or exchange in such tender or exchange offer); and

			
	SP	 	=	  	 the Reference Price per share of Common Stock;

 provided, however, that the Conversion Rate will in no event be adjusted
down pursuant to this Section 5.05(A)(v), except to the extent provided in the immediately following paragraph. The adjustment to the Conversion Rate pursuant to this Section 5.05(A)(v) will be calculated as of the Close of Business on
the last Trading Day of the Tender/Exchange Offer Valuation Period but will be given effect immediately after the Expiration Time, with retroactive effect. If a Note is converted and the Conversion Date (in the case of Physical Settlement) or any
VWAP Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the Tender/Exchange Offer Valuation Period, then, notwithstanding anything to the contrary in this Indenture or the Notes,
the Company will, if necessary, delay the settlement of such conversion until the third (3rd) or, if the T+2 Effective Date has occurred by the last day of the Tender/Exchange Offer Valuation Period, the second (2nd)) Business Day after the last day
of the Tender/Exchange Offer Valuation Period. 
 To the extent such tender or exchange offer is announced but not
consummated (including as a result of the Company being precluded from consummating such tender or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer are rescinded, the
Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender
or exchange offer. 
 (B) No Adjustments in Certain Cases. 

(i) Where Holders Participate in the Transaction or Event Without Conversion. Notwithstanding anything
to the contrary in Section 5.05(A), the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring an adjustment pursuant to Section 5.05(A) (other than a stock split or
combination of the type set forth in Section 5.05(A)(i) or a tender or exchange offer of the type set forth in Section 5.05(A)(v)) if each Holder participates, at the same time and on the same terms as holders of Common Stock, and
solely by virtue of being a Holder of Notes, in such transaction or event without having to convert such Holder’s 

  
 - 52 - 

 
Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the related record date, effective date or Expiration Date,
as applicable; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such date. 

(ii) Certain Events. The Company will not be required to adjust the Conversion Rate except as provided
in Section 5.05 or Section 5.07. Without limiting the foregoing, the Company will not be obligated to adjust the Conversion Rate on account of: 

(1) except as otherwise provided in Section 5.05, the sale of shares of Common Stock
for a purchase price that is less than the market price per share of Common Stock or less than the Conversion Price; 

(2) 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 such plan; 

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

(4) the issuance of any shares of Common Stock pursuant to any option, warrant, right or convertible or
exchangeable security of the Company outstanding as of the Issue Date; 
 (5) a third-party tender offer,
other than a tender offer that is subject to Section 5.05(A)(v). 
 (6) the repurchase of any shares
of Common Stock pursuant to an open market share purchase program or other buyback transaction, including structured or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives, or other buyback
transaction, in each case that is not subject to Section 5.05(A)(v); 
 (7) a change in the par value
of the Common Stock; or 
 (8) accrued and unpaid interest on the Notes. 

(C) Adjustment Deferral. If an adjustment to the Conversion Rate otherwise required by this Article 5 would
result in a change of less than one percent (1%) to the Conversion Rate, then, notwithstanding anything to the contrary in this Article 5, the Company may, at its election, defer and carry forward such adjustment, except that all such
deferred adjustments must be given effect immediately upon the earliest to occur of the following: (i) when all such deferred adjustments would result in an aggregate change of at least one percent (1%) to the Conversion Rate; (ii) the
Conversion Date of any Note (in the case of Physical Settlement) or the 

  
 - 53 - 

 
first VWAP Trading Day of any Observation Period of any Note (in the case of Cash Settlement or Combination Settlement); (iii) the date a Fundamental Change or Make-Whole Fundamental Change
occurs; (iv) the date the Company calls any Notes for Redemption; and (iv) January 15, 2024. 
 (D)
Adjustments Not Yet Effective. Notwithstanding anything to the contrary in this Indenture or the Notes, if: 

(i) a Note is to be converted; 

(ii) the record date or effective date for any event that requires an adjustment to the Conversion Rate
pursuant to Section 5.05(A)(i) to (iv), inclusive, has occurred on or before the Conversion Date for such conversion (in the case of Physical Settlement) or on or before any VWAP Trading Day in the Observation Period for such
conversion (in the case of Combination Settlement), but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date or VWAP Trading Day, as applicable; 

(iii) the Conversion Consideration due upon such conversion (in the case of Physical Settlement) or due in
respect of such VWAP Trading Day (in the case of Combination Settlement) includes any whole shares of Common Stock; and 

(iv) such shares are not entitled to participate in such event (because they were not held on the related
record date or otherwise), 
 then, solely for purposes of such conversion, the Company will, without duplication, give
effect to such adjustment on such Conversion Date (in the case of Physical Settlement) or such VWAP Trading Day (in the case of Combination Settlement), and, for the avoidance of doubt, such shares will not be entitled to participate in such event.
In such case, if the date on which the Company is otherwise required to deliver the consideration due upon such conversion is before the first date on which the amount of such adjustment can be determined, then the Company will delay the settlement
of such conversion until the third (3rd) (or, if the T+2 Effective Date has occurred by such first date, the second (2nd)) Business Day after such first date. 

(E) Conversion Rate Adjustments where Converting Holders Participate in the Relevant Transaction or Event.
Notwithstanding anything to the contrary in this Indenture or the Notes, if: 
 (i) a Conversion Rate
adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to Section 5.05(A); 

(ii) a Note is to be converted pursuant to Physical Settlement or Combination Settlement; 

(iii) the Conversion Date for such conversion (in the case of Physical Settlement) or any VWAP Trading Day in
the Observation Period for such conversion (in the case of Combination Settlement) occurs on or after such Ex-Dividend Date and on or before the related record date; 

  
 - 54 - 

 (iv) the Conversion Consideration due upon such conversion (in
the case of Physical Settlement) or due with respect to such VWAP Trading Day (in the case of Combination Settlement) includes any whole shares of Common Stock based on a Conversion Rate that is adjusted for such dividend or distribution; and 

(v) such shares would be entitled to participate in such dividend or distribution (including pursuant to
Section 5.02(C)), 
 then (x) such Conversion Rate adjustment will not be given effect for such conversion (in the case of
Physical Settlement) or for such VWAP Trading Day (in the case of Combination Settlement); and (y) the shares of Common Stock, if any, issuable upon such conversion (in the case of Physical Settlement) or issuable with respect to such VWAP
Trading Day (in the case of Combination Settlement) based on such unadjusted Conversion Rate will be entitled to participate in such dividend or distribution. 

(F) Stockholder Rights Plans. If any shares of Common Stock are to be issued upon conversion of any Note and, at the
time of such conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under
this Indenture upon such conversion, the rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such time, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to
Section 5.05(A)(iii)(1) on account of such separation as if, at the time of such separation, the Company had made a distribution of the type referred to in such Section to all holders of the Common Stock, subject to readjustment in accordance
with such Section if such rights expire, terminate or are redeemed. 
 (G) Limitation on Effecting Transactions Resulting
in Certain Adjustments. The Company will not engage in or be a party to any transaction or event that would require the Conversion Rate to be adjusted pursuant to Section 5.05(A) or Section 5.07 to an amount that
would result in the Conversion Price per share of Common Stock being less than the par value per share of Common Stock. 

(H) Equitable Adjustments to Last Reported Sale Price. Whenever any provision of this Indenture requires the Company to
calculate the average of the Last Reported Sale Prices, or any function thereof, over a span of multiple days (including to calculate the Stock Price or an adjustment to the Conversion Rate), the Company will make proportionate adjustments, if any,
to such calculations to account for any adjustment to the Conversion Rate pursuant to Section 5.05(A)(i) that becomes effective, or any event requiring such an adjustment to the Conversion Rate where the
Ex-Dividend Date or effective date, as applicable, of such event occurs, at any time during the period over which such average is to be calculated. 

(I) Calculation of Number of Outstanding Shares of Common Stock. For purposes of Section 5.05(A), the number of
shares of Common Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock; and (ii) exclude shares of Common Stock held in the Company’s
treasury (unless the Company pays any dividend or makes any distribution on shares of Common Stock held in its treasury). 

  
 - 55 - 

 (J) Calculations. All calculations with respect to the Conversion Rate and
adjustments thereto will be made to the nearest cent (with 0.5 of a cent rounded upward) or to the nearest 1/10,000th of a share of Common Stock (with 5/100,000ths rounded upward), as applicable. 

(K) Notice of Conversion Rate Adjustments. Upon the effectiveness of any adjustment to the Conversion Rate pursuant to
Section 5.05(A), the Company will promptly send notice to the Holders, the Trustee and the Conversion Agent containing (i) a brief description of the transaction or other event on account of which such adjustment was made; (ii) the
Conversion Rate in effect immediately after such adjustment; and (iii) the effective time of such adjustment. 
 Section 5.06.
VOLUNTARY ADJUSTMENTS. 
 (A) Generally. To the extent permitted by law and
applicable stock exchange rules, the Company, from time to time, may (but is not required to) increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is either (x) in the best interest of the
Company; or (y) advisable to avoid or diminish any income tax imposed on holders of Common Stock or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common Stock or any
similar event; (ii) such increase is in effect for a period of at least twenty (20) Business Days; and (iii) such increase is irrevocable during such period. 

(B) Notice of Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant to
this Section 5.06, then, on or before the effective date of such increase, the Company will send notice to each Holder of such increase, the amount thereof and the period during which such increase will be in effect. 

Section 5.07. ADJUSTMENTS TO THE CONVERSION RATE
IN CONNECTION WITH A MAKE-WHOLE FUNDAMENTAL CHANGE. 

(A) Generally. If a Make-Whole Fundamental Change occurs and the Conversion Date for the conversion of a Note occurs
during the related Make-Whole Fundamental Change Conversion Period, then, subject to this Section 5.07, the Conversion Rate applicable to such conversion will be increased by a number of shares (the “Additional
Shares”) set forth in the table below corresponding (after interpolation as provided in, and subject to, the provisions below) to the effective and the Stock Price of such Make-Whole Fundamental Change:

 If such effective date or Stock Price are not set forth in the table above, then:

 (i) if such Stock Price is between two Stock Prices in the table above or the effective date is between
two effective dates in the table above, then the number of Additional Shares will be determined by a straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices in the table and the earlier
and later effective dates in the table above, as applicable, based on a 365- or 366-day year, as applicable; and 

(ii) if the Stock Price is greater than $250.00 (subject to adjustment in the same manner as the Stock Prices
set forth in the column headings of the table above are adjusted pursuant to Section 5.07(B)), or less than $53.28 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the Conversion Rate. 

Notwithstanding anything to the contrary in this Indenture or the Notes, in no event will the Conversion Rate be increased to
an amount that exceeds 18.7687 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is required to be
adjusted pursuant to Section 5.05(A). 
 (B) Adjustment of Stock Prices and Additional Shares. The Stock
Prices in the first row (i.e., the column headers) of the table set forth in Section 5.07(A) will be adjusted at the same time and for the same events for which, the Conversion Rate is adjusted as a result of the operation of
Section 5.05(A). The adjusted Stock Prices will equal the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock
Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The numbers of Additional Shares in the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same
events for which, the Conversion Rate is adjusted pursuant to Section 5.07(A). 
 (C) Notice of the Occurrence of
a Make-Whole Fundamental Change. The Company will notify the Holders, the Trustee and the Conversion Agent of each Make-Whole Fundamental Change in accordance with Section 5.01(C)(i)(3)(b). 

(D) Settlement of Cash Make-Whole Fundamental Changes. For the avoidance of doubt, if holders of Common Stock receive
solely cash in a Make-Whole Fundamental Change, then, pursuant to Section 5.09, conversions of Notes will thereafter be settled no later than the third (3rd) Business Day after the relevant Conversion Date. 

Section 5.08. EXCHANGE IN LIEU OF CONVERSION. 

When a Holder surrenders any Note for conversion, the Company may, at its election (an “Exchange Election”),
direct the Conversion Agent to surrender, on or prior to the Business Day immediately following the Conversion Date, such Note to one or more financial institutions designated by the Company for exchange in lieu of conversion. In order to accept any
Notes surrendered for conversion, the designated financial institution(s) must agree to timely pay or 

  
 - 57 - 

 
deliver, as the case may be, in exchange for such Note, the Conversion Consideration that would otherwise be due pursuant to this Article 5. To make an Exchange Election with respect to
any Note, the Company must, by the Close of Business on the Business Day following the relevant Conversion Date, notify in writing the Trustee, the Conversion Agent (if other than the Trustee) and the Holder of such Note and the Company must notify
the designated financial institution(s) of the relevant deadline for delivery of the Conversion Consideration and the type of Conversion Consideration to be paid or delivered, as the case may be. 

Any Notes exchanged by the designated financial institution(s) will remain outstanding, subject to the Depositary Procedures,
if applicable. If any financial institution agrees to accept any Notes for exchange but does not timely pay or deliver, as the case may be, the related Conversion Consideration, or if such designated financial institution does not accept the Notes
for exchange, then the Company will pay or deliver, as the case may be, the relevant Conversion Consideration, as, and at the time, required pursuant to this Indenture as if the Company had not made the exchange election. 

The Company’s designation of any financial institution(s) to which the Notes may be submitted for exchange does not
require such financial institution(s) to accept any Notes. 
 Section 5.09. EFFECT OF COMMON
STOCK CHANGE EVENT. 
 (A) Generally. If there occurs any: 

(i) recapitalization, reclassification or change of the Common Stock (other than (x) changes solely
resulting from a subdivision or combination of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value and (z) stock splits and stock combinations that do not involve the issuance of
any other series or class of securities); 
 (ii) consolidation, merger, combination or binding share
exchange involving the Company; or 
 (iii) sale, lease or other transfer of all or substantially all of the
assets of the Company and its Subsidiaries, taken as a whole, to any Person, 
 and, as a result which, the Common Stock is converted into,
or is exchanged for, or represents solely the right to receive, other securities, cash or other property, or any combination of the foregoing (such an event, a “Common Stock Change Event,” and such other securities, cash or
property, the “Reference Property,” and the amount and kind of Reference Property that a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect
to any arrangement not to issue or deliver a fractional portion of any security or other property), a “Reference Property Unit”), then, notwithstanding anything to the contrary in this Indenture or the Notes, 

(1) at the effective time of such Common Stock Change Event, (I) the Conversion Consideration due upon
conversion of any Note and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 5 (or in any related definitions) were

  
 - 58 - 

 
instead a reference to the same number of Reference Property Units; (II) for purposes of Section 4.03, each reference to any number of shares of Common Stock in
such Section (or in any related definitions) will instead be deemed to be a reference to the same number of Reference Property Units; and (III) for purposes of the definition of “Fundamental Change” and “Make-Whole Fundamental
Change,” (x) the terms “Common Stock” and “common equity” will be deemed to mean the common equity (which term will be deemed to include depositary receipts or shares representing common equity), if any, forming part of such
Reference Property; and (y) references to the Company will be deemed to be references to the entity that is the issuer of such common equity; 

(2) if such Reference Property Unit consists entirely of cash, then the Company will be deemed to elect Cash
Settlement and will pay the cash due in respect of all conversions whose Conversion Date occurs on or after the effective date of such Common Stock Change Event no later than the third (3rd) (or, if the T+2 Effective Date has occurred by the
relevant Conversion Date, the second (2nd)) Business Day after such Conversion Date; and 
 (3) for these
purposes, the Daily VWAP or Last Reported Sale Price of any Reference Property Unit or portion thereof that does not consist of a class of securities will be the fair value of such Reference Property Unit or portion thereof, as applicable,
determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof). 

If the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of
stockholder election, then the composition of the Reference Property Unit will be deemed to be (x) the weighted average, per share of Common Stock, 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, per share of Common Stock, by the holders of Common Stock. The Company will
notify Holders of the weighted average as soon as practicable after such determination is made. 
 At or before the
effective time of such Common Stock Change Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee
a supplemental indenture pursuant to Section 8.01(F), which supplemental indenture will give effect to the provisions of this Section 5.09(A) and contain such other provisions as the Company reasonably determines are appropriate to
preserve the economic interests of the Holders. If such Reference Property includes, in whole or in part, any stock or other securities, then such supplemental indenture will, to the extent applicable, provide for subsequent adjustments to the
Conversion Rate in a manner consistent with Section 5.05. In addition, if the Reference Property includes, in whole or in part, shares of stock or other securities or assets (other than cash or cash equivalents) of a Person
other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain such additional provisions the Company reasonably determines are appropriate to preserve the economic
interests of the 

  
 - 59 - 

 
Holders. 
 (B) Notice of Common Stock Change Events. No later
than the effective date of each Common Stock Change Event, the Company will notify the Holders and the Trustee of such Common Stock Change Event, including a brief description of such Common Stock Change Event, its effective date and a brief
description of the anticipated change in the conversion right of the Notes. 
 (C) Compliance Covenant. The Company
will not become a party to any Common Stock Change Event unless its terms are consistent with this Section 5.09. 

Article 6. SUCCESSORS 

Section 6.01. WHEN THE COMPANY MAY MERGE, ETC. 

(A) Generally. The Company will not consolidate with or merge with or into, or sell, lease or otherwise transfer, in one
transaction or a series of transactions, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to another Person (a “Business Combination Event”), unless: 

(i) the resulting, surviving or transferee Person either (x) is the Company or (y) if not the
Company, is a corporation (the “Successor Corporation”) duly organized and existing under the laws of the United States of America, any State thereof or the District of Columbia that expressly assumes (by executing and delivering to
the Trustee, at or before the effective time of such Business Combination Event, a supplemental indenture pursuant to Section 8.01(E)) all of the Company’s obligations under this Indenture and the Notes; and 

(ii) immediately after giving effect to such Business Combination Event, no Default or Event of Default will
have occurred and be continuing. 
 Section 6.02. SUCCESSOR CORPORATION SUBSTITUTED. 

At the effective time of any Business Combination Event that complies with Section 6.01, the
Successor Corporation (if not the Company) will succeed to, and may exercise every right and power of, the Company under this Indenture and the Notes with the same effect as if such Successor Corporation had been named as the Company in this
Indenture and the Notes, and, except in the case of a lease, the predecessor Company will be discharged from its obligations under this Indenture and the Notes. 

Article 7. DEFAULTS AND REMEDIES 

Section 7.01. EVENTS OF DEFAULT. 

(A) Definition of Events of Default. “Event of Default” means the occurrence of any of the following:

 (i) a default in the payment when due (whether at maturity, upon Redemption

  
 - 60 - 

 
or Repurchase Upon Fundamental Change or otherwise) of the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, any Note; 

(ii) a default for thirty (30) days in the payment when due of interest on any Note; 

(iii) the Company’s failure to deliver, when required by this Indenture, a Fundamental Change Notice or a
notice pursuant to Section 5.01(C)(i)(3)(b); 
 (iv) a default in the Company’s obligation to
convert a Note in accordance with Article 5 upon the exercise of the conversion right with respect thereto and such failure continues for five (5) Business Days; 

(v) a default in the Company’s obligations under Article 6; 

(vi) a default in any of the Company’s obligations or agreements under this Indenture or the Notes (other
than a default set forth in clause (i), (ii), (iii), (iv) or (v) of this Section 7.01(A)) where such default is not cured or waived within sixty (60) days after notice to the Company by the
Trustee, or to the Company and the Trustee by Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, which notice must specify such default, demand that it be remedied and state that the such
notice is a “Notice of Default”; 
 (vii) a default by the Company or any of its Subsidiaries with
respect to any one or more mortgages, agreements or other instruments under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed of at least fifty million dollars ($50,000,000) (or its foreign
currency equivalent) in the aggregate of the Company or any of its Subsidiaries, whether such indebtedness exists as of the Issue Date or is thereafter created, where such default: 

(1) constitutes a failure to pay the principal of any of such indebtedness when due and payable (after the
expiration of all applicable grace periods) at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise; or 

(2) results in such indebtedness becoming or being declared due and payable before its stated maturity (an
“Acceleration”), 
 and, in either case, such Acceleration has not been rescinded or annulled or such
failure to pay or default is not cured or waived, or such indebtedness is not paid or discharged in full, within sixty (60) days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least twenty
five percent (25%) of the aggregate principal amount of Notes then outstanding; and 
 (viii) the Company or
any of its Significant Subsidiaries, pursuant to or within the meaning of any Bankruptcy Law, either: 
 (1)
commences a voluntary case or proceeding; 

  
 - 61 - 

 (2) consents to the entry of an order for relief against it in an
involuntary case or proceeding; 
 (3) consents to the appointment of a custodian of it or for any
substantial part of its property; 
 (4) makes a general assignment for the benefit of its creditors; 

(5) takes any comparable action under any foreign Bankruptcy Law; or 

(6) generally is not paying its debts as they become due; or 

(ix) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that either: 

(1) is for relief against Company or any of its Significant Subsidiaries in an involuntary case or proceeding;

 (2) appoints a custodian of the Company or any of its Significant Subsidiaries, or for any substantial
part of the property of the Company or any of its Significant Subsidiaries; 
 (3) orders the winding up or
liquidation of the Company or any of its Significant Subsidiaries; or 
 (4) grants any similar relief under
any foreign Bankruptcy Law, 
 and, in each case under this Section 7.01(A)(ix), such order or decree remains unstayed
and in effect for at least sixty (60) days. 
 (B) Cause Irrelevant. Each of the events set forth in Section
7.01(A) will constitute an Event of Default regardless of the cause thereof or whether voluntary or involuntary or 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. 
 Section 7.02. ACCELERATION. 

(A) Automatic Acceleration in Certain Circumstances. If an Event of Default set forth in Section 7.01(A)(viii) or
7.01(A)(ix) occurs with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company), then the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding will immediately
become due and payable without any further action or notice by any Person. 
 (B) Optional Acceleration. Subject to
Section 7.03, if an Event of Default (other than an Event of Default set forth in Section 7.01(A)(viii) or 7.01(A)(ix) with respect to the Company and not solely with respect to a Significant Subsidiary of the
Company) occurs and is continuing, then the Trustee, by notice to the Company, or Holders of at least twenty five percent (25%) of 

  
 - 62 - 

 
the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the Notes
then outstanding to become due and payable immediately. 
 (C) Rescission of Acceleration. Notwithstanding anything
to the contrary in this Indenture or the Notes, the Holders of a majority in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, on behalf of all Holders, rescind any 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 (except the non-payment of
principal of, or interest on, the Notes that has become due solely because of such acceleration) have been cured or waived. No such rescission will affect any subsequent Default or impair any right consequent thereto. 

Section 7.03. SOLE REMEDY FOR A FAILURE TO
REPORT. 
 (A) Generally. Notwithstanding anything to the contrary in this Indenture or the Notes,
the Company may elect that the sole remedy for any Event of Default (a “Reporting Event of Default”) pursuant to Section 7.01(A)(vi) arising from the Company’s failure to comply with
Section 3.02 will, for each of the first three hundred and sixty (360) calendar days on which a Reporting Event of Default has occurred and is continuing, consist exclusively of the accrual of Special Interest on the
Notes. If the Company has made such an election, then (i) the Notes will be subject to acceleration pursuant to Section 7.02 on account of the relevant Reporting Event of Default from, and including, the three hundred
and sixty first (361st) calendar day on which a Reporting Event of Default has occurred and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when due; and (ii) Special Interest will cease to accrue on any
Notes from, and including, such three hundred and sixty first (361st) calendar day (it being understood that interest on any defaulted Special Interest will nonetheless accrue pursuant to Section 2.05(B)). 

(B) Amount and Payment of Special Interest. Any Special Interest that accrues on a Note pursuant to Section
7.03(A) will be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate per annum equal to one quarter of one percent (0.25%) of the principal amount thereof for the first one hundred and
eighty (180) days on which Special Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof from the one hundred eighty first (181st) day to, and including, the three hundred
sixtieth (360th) day on which Special Interest accrues; provided, however, that in no event will Special Interest, together with any Additional Interest, accrue on any day on a Note at a combined rate per annum that exceeds one half of
one percent (0.50%), regardless of the number of events or circumstances giving rise to the accrual of Special Interest or Additional Interest. For the avoidance of doubt, any Special Interest that accrues on a Note will be in addition to the Stated
Interest that accrues on such Note and, subject to the proviso of the immediately preceding sentence, in addition to any Additional Interest that accrues on such Note. 

(C) Notice of Election. To make the election set forth in Section 7.03(A), the Company must send to the Holders,
the Trustee and the Paying Agent, before the date on which each Reporting Event of Default first occurs, a notice that (i) briefly describes of the report(s) 

  
 - 63 - 

 
that the Company failed to file with or furnish to the SEC; (ii) states that the Company is electing that the sole remedy for such Reporting Event of Default consist of the accrual of
Special Interest; and (iii) briefly describes the periods during which and rate at which Special Interest will accrue and the circumstances under which the Notes will be subject to acceleration on account of such Reporting Event of Default.

 (D) No Effect on Other Events of Default. No election pursuant to this Section 7.03 with
respect to a Reporting Event of Default will affect the rights of any Holder with respect to any other Event of Default, including with respect to any other Reporting Event of Default. 

Section 7.04. OTHER REMEDIES. 

(A) Trustee May Pursue All Remedies. If an Event of Default occurs and is continuing, then the Trustee may pursue any
available remedy to collect the payment of any amounts due with respect to the Notes or to enforce the performance of any provision of this Indenture or the Notes. 

(B) Procedural Matters. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not
produce any of them in such proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy following an Event of Default will not impair the right or remedy or constitute a waiver of, or acquiescence in, such Event of
Default. All remedies will be cumulative to the extent permitted by law. 
 Section 7.05. WAIVER OF
PAST DEFAULTS. 
 An Event of Default pursuant to clause (i), (ii),
(iv) or (vi) of Section 7.01(A) (that, in the case of clause (vi) only, results from a Default under any covenant that cannot be amended without the consent of each affected Holder), and a Default that could
lead to such an Event of Default, can be waived only with the consent of each affected Holder. Each other Default or Event of Default may be waived, on behalf of all Holders, by the Holders of a majority in aggregate principal amount of the Notes
then outstanding. If an Event of Default is so waived, then it will cease to exist. If a Default is so waived, then it will be deemed to be cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will
extend to any subsequent or other Default or Event of Default or impair any right arising therefrom. 
 Section 7.06. CONTROL
BY MAJORITY. 
 Holders of a majority in aggregate principal amount of the Notes then
outstanding may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law, this Indenture or the Notes, or that, subject to Section 10.01, the Trustee determines may be unduly prejudicial to the rights of other Holders or may involve the Trustee in liability, unless the Trustee
is offered security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such direction. 

  
 - 64 - 

 Section 7.07. LIMITATION ON SUITS. 

No Holder may pursue any remedy with respect to this Indenture or the Notes (except to enforce (x) its rights to receive
the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, or interest on, any Notes; or (y) the Company’s obligations to convert any Notes pursuant to Article 5), unless: 

(A) such Holder has previously delivered to the Trustee notice that an Event of Default is continuing; 

(B) Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding deliver a
written request to the Trustee to pursue such remedy; 
 (C) such Holder or Holders offer and, if requested, provide to the
Trustee security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such request; 

(D) the Trustee does not comply with such request within sixty (60) calendar days after its receipt of such request and
such offer of security or indemnity; and 
 (E) during such sixty (60) calendar day period, Holders of a majority in
aggregate principal amount of the Notes then outstanding do not deliver to the Trustee a direction that is inconsistent with such request. 

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority
over another Holder. The Trustee will have no duty to determine whether any Holder’s use of this Indenture complies with the preceding sentence. 

Section 7.08. ABSOLUTE RIGHT OF HOLDERS TO
INSTITUTE SUIT FOR THE ENFORCEMENT OF THE RIGHT TO RECEIVE PAYMENT
AND CONVERSION CONSIDERATION. 
 Notwithstanding anything to the contrary in
this Indenture or the Notes, the right of each Holder of a Note to bring suit for the enforcement of any payment or delivery, as applicable, of the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, or any interest on,
or the Conversion Consideration due pursuant to Article 5 upon conversion of, such Note on or after the respective due dates therefor provided in this Indenture and the Notes, will not be impaired or affected without the consent of such
Holder. 
 Section 7.09. COLLECTION SUIT BY TRUSTEE. 

The Trustee will have the right, upon the occurrence and continuance of an Event of Default pursuant to clause
(i), (ii) or (iv) of Section 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for the total unpaid or undelivered principal of, or Redemption Price or Fundamental
Change Repurchase Price for, or interest on, or Conversion Consideration due pursuant to Article 5 upon conversion of, the Notes, as applicable, and, to the extent lawful, any Default Interest on any Defaulted Amounts, and such further
amounts sufficient to cover the costs and expenses of collection, including all amounts owed to it under Section 10.06. 

  
 - 65 - 

 Section 7.10. TRUSTEE MAY FILE PROOFS
OF CLAIM. 
 The Trustee has the right to (A) file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes) or its creditors or property and
(B) collect, receive and distribute any money or other property payable or deliverable on any such claims. Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee consents to the making
of such payments directly to the Holders, to pay to the Trustee any amount due to the Trustee for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to the
Trustee pursuant to Section 10.06. To the extent that the payment of any such compensation, expenses, disbursements, advances and other amounts out of the estate in such proceeding, is denied for any reason, payment of the
same will be secured by a lien on, and will be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding (whether in liquidation or under any plan of
reorganization or arrangement or otherwise). Nothing in this Indenture will be deemed to authorize the Trustee to authorize, consent to, accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 7.11. PRIORITIES. 

The Trustee will pay or deliver in the following order any money or other property that it collects pursuant to this Article
7: 
 First: to the Trustee and any Note Agent and their respective agents and attorneys for
amounts due hereunder, including payment of all fees, compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders for unpaid amounts or other property due on the Notes, including the principal of, or
the Redemption Price or Fundamental Change Repurchase Price for, or any interest on, or any Conversion Consideration due upon conversion of, the Notes, ratably, and without preference or priority of any kind, according to such amounts or other
property due and payable on all of the Notes; and 
 Third: to the Company or such other Person as a
court of competent jurisdiction directs. 
 The Trustee may fix a record date and payment date for any payment or delivery
to the Holders pursuant to this Section 7.11, in which case the Trustee will instruct the Company to, and the Company will, deliver, at least fifteen (15) calendar days before such record date, to each Holder and the
Trustee a notice stating such record date, such payment date and the amount of such payment or nature of such delivery, as applicable. 

  
 - 66 - 

 Section 7.12. UNDERTAKING FOR COSTS. 

In any suit for the enforcement of any right or remedy under this Indenture or the Notes or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking to pay the costs of such suit, and (B) assess reasonable costs (including reasonable
attorneys’ fees) against any litigant party in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant party; provided, however, that this Section 7.12
does not apply to any suit by the Trustee, any suit by a Holder pursuant to Section 7.08 or any suit by one or more Holders of more than ten percent (10%) in aggregate principal amount of the Notes then outstanding. 

Article 8. AMENDMENTS, SUPPLEMENTS AND WAIVERS 

Section 8.01. WITHOUT THE CONSENT OF HOLDERS. 

Notwithstanding anything to the contrary in Section 8.02, the Company and the Trustee may amend or
supplement this Indenture or the Notes without the consent of any Holder to: 
 (A) cure any ambiguity or correct any
omission, defect or inconsistency in this Indenture or the Notes; 
 (B) add guarantees with respect to the Company’s
obligations under this Indenture or the Notes; 
 (C) secure the Notes; 

(D) add to the Company’s covenants or Events of Default for the benefit of the Holders or surrender any right or power
conferred on the Company; 
 (E) provide for the assumption of the Company’s obligations under this Indenture and the
Notes pursuant to, and in compliance with, Article 6; 
 (F) enter into supplemental indentures pursuant to, and in
accordance with, Section 5.09 in connection with a Common Stock Change Event; 
 (G) irrevocably
elect or eliminate any Settlement Method or Specified Dollar Amount; provided, however, that no such election or elimination will affect any settlement method theretofore elected (or deemed to be elected) with respect to any Note
pursuant to Section 5.03(A); 
 (H) evidence or provide for the acceptance of the appointment, under this
Indenture, of a successor Trustee; 
 (I) conform the provisions of this Indenture and the Notes to the “Description of
Notes” section of the Company’s Preliminary Offering Memorandum, dated April 25, 2017, as supplemented by the related Pricing Term Sheet, dated April 26, 2017; 

  
 - 67 - 

 (J) provide for or confirm the issuance of additional Notes pursuant to
Section 2.03(B); 
 (K) comply with any requirement of the SEC in connection with any qualification of this Indenture
or any supplemental indenture under the Trust Indenture Act, as then in effect; or 
 (L) make any other change to this
Indenture or the Notes that does not, individually or in the aggregate with all other such changes, adversely affect the rights of the Holders, as such, in any material respect. 

Section 8.02. WITH THE CONSENT OF HOLDERS. 

(A) Generally. Subject to Sections 8.01, 7.05 and 7.08 and the immediately following sentence, the
Company and the Trustee may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, amend or supplement this Indenture or the Notes or waive compliance with any provision of this Indenture or the
Notes. Notwithstanding anything to the contrary in the foregoing sentence, without the consent of each affected Holder, no amendment or supplement to this Indenture or the Notes, or waiver of any provision of this Indenture or the Notes, may: 

(i) reduce the principal, or extend the stated maturity, of any Note; 

(ii) reduce the Redemption Price or Fundamental Change Repurchase Price for any Note or change the times at
which, or the circumstances under which, the Notes may or will be redeemed or repurchased by the Company; 

(iii) reduce the rate, or extend the time for the payment, of interest on any Note; 

(iv) make any change that adversely affects the conversion rights of any Note; 

(v) impair the absolute rights of any Holder set forth in Section 7.08 (as such
section is in effect on the Issue Date); 
 (vi) change the ranking of the Notes; 

(vii) make any note payable in money, or at a place of payment, other than that stated in this Indenture or the
Note; 
 (viii) reduce the amount of Notes whose Holders must consent to any amendment, supplement, waiver or
other modification; or 
 (ix) make any direct or indirect change to any amendment, supplement, waiver or
modification provision of this Indenture or the Notes that requires the consent of each affected Holder. 
 For the
avoidance of doubt, pursuant to clauses (i), (ii), (iii) and (iv) of this Section 8.02(A), no amendment or supplement to this Indenture or the Notes, or waiver of any provision

  
 - 68 - 

 
of this Indenture or the Notes, may change the amount or type of consideration due on any Note (whether on an Interest Payment Date, Redemption Date, Fundamental Change Repurchase Date or the
Maturity Date or upon conversion, or otherwise), or the date(s) or time(s) such consideration is payable or deliverable, as applicable, without the consent of each affected Holder. 

(B) Holders Need Not Approve the Particular Form of any Amendment. A consent of any Holder pursuant to this
Section 8.02 need approve only the substance, and not necessarily the particular form, of the proposed amendment, supplement or waiver. 

Section 8.03. NOTICE OF AMENDMENTS, SUPPLEMENTS AND WAIVERS.

 Promptly after any amendment, supplement or waiver pursuant to Section 8.01 or 8.02 becomes
effective, the Company will send to the Holders and the Trustee notice that (A) describes the substance of such amendment, supplement or waiver in reasonable detail and (B) states the effective date thereof. The failure to send, or the
existence of any defect in, such notice will not impair or affect the validity of such amendment, supplement or waiver. 
 Section 8.04.
REVOCATION, EFFECT AND SOLICITATION OF CONSENTS; SPECIAL RECORD DATES; ETC. 

(A) Revocation and Effect of Consents. The consent of a Holder of a Note to an amendment, supplement or waiver will bind
(and constitute the consent of) each subsequent Holder of any Note to the extent the same evidences any portion of the same indebtedness as the consenting Holder’s Note, subject to the right of any Holder of a Note to revoke (if not prohibited
pursuant to Section 8.04(B)) any such consent with respect to such Note by delivering notice of revocation to the Trustee before the time such amendment, supplement or waiver becomes effective. 

(B) Special Record Dates. The Company may, but is not required to, fix a record date for the purpose of determining the
Holders entitled to consent or take any other action in connection with any amendment, supplement or waiver pursuant to this Article 8. If a record date is fixed, then, notwithstanding anything to the contrary in Section 8.04(A), only
Persons who are Holders as of such record date (or their duly designated proxies) will be entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of whether such Persons continue to be Holders
after such record date; provided, however, that no such consent will be valid or effective for more than one hundred and twenty (120) calendar days after such record date. 

(C) Solicitation of Consents. For the avoidance of doubt, each reference in this Indenture or the Notes to the consent
of a Holder will be deemed to include any such consent obtained in connection with a repurchase of, or tender or exchange offer for, any Notes. 

(D) Effectiveness and Binding Effect. Each amendment, supplement or waiver pursuant to this Article 8 will
become effective in accordance with its terms and, when it becomes effective with respect to any Note (or any portion thereof), will thereafter bind every Holder of such Note (or such portion). 

  
 - 69 - 

 Section 8.05. NOTATIONS AND EXCHANGES. 

If any amendment, supplement or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion,
require the Holder of such Note to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company on such Note and return such Note to such Holder. Alternatively, at its discretion, the Company may, in
exchange for such Note, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Note that reflects the changed terms. The failure to make any appropriate notation
or issue a new Note pursuant to this Section 8.05 will not impair or affect the validity of such amendment, supplement or waiver. 

Section 8.06. TRUSTEE TO EXECUTE SUPPLEMENTAL INDENTURES. 

The Trustee will execute and deliver any amendment or supplemental indenture authorized pursuant to this Article 8;
provided, however, that the Trustee need not (but may, in its sole and absolute discretion) execute or deliver any such amendment or supplemental indenture that adversely affects the Trustee’s rights, duties, liabilities or
immunities. In executing any amendment or supplemental indenture, the Trustee will be entitled to receive, and (subject to Sections 10.01 and 10.02) will be fully protected in relying on, an Officer’s Certificate and an
Opinion of Counsel stating that (A) the execution and delivery of such amendment or supplemental indenture is authorized or permitted by this Indenture; and (B) in the case of the Opinion of Counsel, such amendment or supplemental
indenture is valid, binding and enforceable against the Company in accordance with its terms. 
 Article 9. SATISFACTION AND DISCHARGE

 Section 9.01. TERMINATION OF COMPANY’S OBLIGATIONS. 

This Indenture will be discharged, and will cease to be of further effect as to all Notes issued under this Indenture, when:

 (A) all Notes then outstanding (other than Notes replaced pursuant to Section 2.13) have
(A) been delivered to the Trustee for cancellation; or (B) become due and payable (whether on a Redemption Date, a Fundamental Change Repurchase Date, the Maturity Date, upon conversion or otherwise) for an amount of cash or Conversion
Consideration, as applicable, that has been fixed; 
 (B) the Company has caused there to be irrevocably deposited with the
Trustee, or with the Paying Agent (or, with respect to Conversion Consideration, the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered to the Holders, cash (or, with respect to Notes to be
converted, Conversion Consideration) sufficient to satisfy all amounts or other property due on all Notes then outstanding (other than Notes replaced pursuant to Section 2.13); 

(C) the Company has paid all other amounts payable by it under this Indenture; and 

provided, however, that Article 10 and Section 11.01 will survive such discharge and, until no
Notes remain outstanding, Section 2.15 and the obligations of the Trustee, the Paying Agent and 

  
 - 70 - 

 
the Conversion Agent with respect to money or other property deposited with them will survive such discharge. 

At the Company’s request, upon the Company’s delivery to the Trustee of an Officer’s Certificate and an Opinion
of Counsel, each stating that the conditions precedent to the discharge of this Indenture have been satisfied, the Trustee will acknowledge the satisfaction and discharge of this Indenture. 

Section 9.02. REPAYMENT TO COMPANY. 

Subject to applicable unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will promptly notify the
Company if there exists (and, at the Company’s request, promptly deliver to the Company) any cash, Conversion Consideration or other property held by any of them for payment or delivery on the Notes that remain unclaimed two (2) years
after the date on which such payment or delivery was due. After such delivery to the Company, the Trustee, the Paying Agent and the Conversion Agent will have no further liability to any Holder with respect to such cash, Conversion Consideration or
other property, and Holders entitled to the payment or delivery of such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor of the Company. 

Section 9.03. REINSTATEMENT. 

If the Trustee, the Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it
pursuant to Section 9.01 because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains or otherwise prohibits such application, then the discharge of this
Indenture pursuant to Section 9.01 will be rescinded; provided, however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to the Holders thereof, then the Company
will be subrogated to the rights of such Holders to receive such cash or other property from the cash or other property, if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable. 

Article 10. TRUSTEE 

Section 10.01. DUTIES OF THE TRUSTEE. 

(A) If an Event of Default has occurred and is continuing, the Trustee will 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. 

(B) Except during the continuance of an Event of Default: 

(i) the duties of the Trustee will be determined solely by the express provisions of this Indenture, and the
Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations will be read into this Indenture against the Trustee; and 

  
 - 71 - 

 (ii) in the absence of bad faith or willful misconduct on its
part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon Officer’s Certificates or Opinions of Counsel that are provided to the Trustee and conform to the
requirements of this Indenture. However, in the case of any such Officer’s Certificates or Opinions of Counsel that, by any provision under this Indenture, are specifically required to be furnished to the Trustee, the Trustee will examine the
certificates and opinions to determine whether or not they conform to the requirements of this Indenture. 
 (C) The Trustee
may not be relieved from liabilities for its negligence or willful misconduct, except that: 
 (i) this
paragraph will not limit the effect of Section 10.01(B); 
 (ii) the Trustee will not be liable for
any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 

(iii) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in
accordance with a direction received by it pursuant to Section 7.06. 
 (D) Each provision of this
Indenture that in any way relates to the Trustee is subject to paragraphs (A), (B) and (C) of this Section 10.01, regardless of whether such provision so expressly provides. 

(E) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. 

(F) The Trustee will not be liable for interest on any money received by it, except as the Trustee may agree in writing with
the Company. Money held in trust by the Trustee need not be segregated from other funds, except to the extent required by law. 
 Section 10.02.
RIGHTS OF THE TRUSTEE. 
 (A) The Trustee may conclusively
rely on any document that is believes to be genuine and signed or presented by the proper Person, and the Trustee need not investigate any fact or matter stated in such document; provided, however, that the Trustee may make such
further inquiry or investigation into such fact or matter, and, if the Trustee will determine to make such further inquiry or investigation, it will be entitled to examine the books, records and premises of the Company, as the sole cost of the
Company. 
 (B) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate, an Opinion of
Counsel or both. The Trustee will 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. The Trustee may consult with counsel; and the written advice of such
counsel, or any Opinion of Counsel, will constitute full and complete authorization of the Trustee to take or omit to take any action in good faith in reliance thereon without liability. 

  
 - 72 - 

 (C) The Trustee may act through its attorneys and agents and will not be
responsible for the misconduct or negligence of any such agent appointed with due care. 
 (D) The Trustee will not be
liable for any action it takes or omits to take in good faith and that it believes to be authorized or within the rights or powers vested in it by this Indenture. 

(E) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company will
be sufficient if signed by an Officer of the Company. 
 (F) The Trustee need not exercise any rights or powers vested in it
by this Indenture at the request or direction of any Holder unless such Holder has offered the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense that it may incur in complying with such request or
direction. 
 (G) In no event will the Trustee be responsible or liable for special, indirect, punitive or consequential
loss or damage of any kind whatsoever (including loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

(H) The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified,
are extended to, and will be enforceable by, the Trustee in each of its capacities under this Indenture. 
 (I) The Trustee
will not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. 
 Section 10.03.
INDIVIDUAL RIGHTS OF THE TRUSTEE. 
 The
Trustee, in its individual or any other capacity, may become the owner or pledgee of any Note and may otherwise deal with the Company or any of its Affiliates with the same rights that it would have if it were not Trustee; provided,
however, that if the Trustee acquires a “conflicting interest” (within the meaning of Section 310(b) of the Trust Indenture Act), then it must eliminate such conflict within ninety (90) days or resign as Trustee. Each Note
Agent will have that same rights and duties as the trustee under this Section 10.03. 
 Section 10.04.
TRUSTEE’S DISCLAIMER. 
 The Trustee will not be (A) responsible
for, and makes no representation as to, the validity or adequacy of this Indenture or the Notes; (B) accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction
under any provision of this Indenture; (C) responsible for the use or application of any money received by any Paying Agent other than the Trustee; and (D) responsible for any statement or recital in this Indenture, the Notes or any other
document relating to the sale of the Notes or this Indenture, other than the Trustee’s certificate of authentication. 
 Section 10.05.
NOTICE OF DEFAULTS. 
 If a Default or Event of Default occurs and is
continuing and is known to a Responsible 

  
 - 73 - 

 
Officer of the Trustee, then the Trustee will send Holders a notice of such Default or Event of Default within ninety (90) days after it occurs or, if it is not known to a Responsible
Officer of the Trustee at such time, promptly (and in any event within ten (10) Business Days) after it becomes known to a Responsible Officer; provided, however, that, except in the case of a Default or Event of Default in the
payment of the principal of, or interest on, any Note, the Trustee may withhold such notice if and for so long as it in good faith determines that withholding such notice is in the interests of the Holders. 

Section 10.06. COMPENSATION AND INDEMNITY. 

(A) The Company will, from time to time, pay the Trustee such compensation for its acceptance of this Indenture and services
under this Indenture as agreed to with the Trustee from time to time. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. In addition to the compensation for the Trustee’s services,
the Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it under this Indenture, including the reasonable compensation, disbursements and expenses of the Trustee’s
agents and counsel. 
 (B) The Company will indemnify the Trustee against any and all losses, liabilities or expenses
incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this
Section 10.06) and defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties under this
Indenture, except to the extent any such loss, liability or expense may be attributable to its negligence or willful misconduct. The Trustee will promptly notify the Company of any claim for which it may seek indemnity, but the Trustee’s
failure to so notify the Company will not relieve the Company of its obligations under this Section 10.06(B). The Company will defend such claim, and the Trustee will cooperate in such defense. If the Trustee is advised by counsel that it may
have defenses available to it that are in conflict with the defenses available to the Company, or that there is an actual or potential conflict of interest, then the Trustee may retain separate counsel, and the Company will pay the reasonable fees
and expenses of such counsel (including the reasonable fees and expenses of counsel to the Trustee incurred in evaluating whether such a conflict exists). The Company need not pay for any settlement of any such claim made without its consent, which
consent will not be unreasonably withheld. 
 (C) The obligations of the Company under this
Section 10.06 will survive the resignation or removal of the Trustee and the discharge of this Indenture. 

(D) To secure the Company’s payment obligations in this Section 10.06, the Trustee will have a
lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, or interest on, particular Notes, which lien will survive the discharge of this Indenture, and for the avoidance of
doubt, such lien will not be extended in a manner that would conflict with the Company’s obligations to its other creditors. 

(E) If the Trustee incurs expenses or renders services after an Event of Default pursuant to clause
(viii) or (ix) of Section 7.01(A) occurs, then such expenses and the 

  
 - 74 - 

 
compensation for such services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 

Section 10.07. REPLACEMENT OF THE TRUSTEE.

(B) The Trustee may resign at any time and be discharged from the trust created by this Indenture by so notifying the Company.
The Holders of a majority in aggregate principal amount of the Notes then outstanding may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 

(i) the Trustee fails to comply with Section 10.09; 

(ii) the Trustee is adjudged to be bankrupt or insolvent or an order for relief is entered with respect to the
Trustee under any Bankruptcy Law; 
 (iii) a custodian or public officer takes charge of the Trustee or its
property; or 
 (iv) the Trustee becomes incapable of acting. 

(C) If the Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, then (i) the
Company will promptly appoint a successor Trustee; and (ii) at any time within one (1) year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the Notes then outstanding may appoint a
successor Trustee to replace such successor Trustee appointed by the Company. 
 (D) If a successor Trustee does not take
office within thirty (30) days after the retiring Trustee resigns or is removed, then the retiring Trustee, the Company or the Holders of at least ten percent (10%) in aggregate principal amount of the Notes then outstanding may petition any
court of competent jurisdiction for the appointment of a successor Trustee. 
 (E) If the Trustee, after written request by
a Holder of at least six (6) months, fails to comply with Section 10.09, then such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(F) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company, upon
which notice the resignation or removal of the retiring Trustee will become effective and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send notice of its succession
to Holders. The retiring Trustee will, upon payment of all amounts due to it under this Indenture, promptly transfer all property held by it as Trustee to the successor Trustee, which property will, for the avoidance of doubt, be subject to the lien
provided for in Section 10.06(D).

 Section 10.08. SUCCESSOR TRUSTEE BY MERGER,
ETC.

 Section 10.09.
ELIGIBILITY; DISQUALIFICATION.
