securities dealer selected by the Company on any determination date, then the Trading Price per $1,000 principal amount of Notes on such determination date shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the

ARTICLE 2 
 ISSUE,
DESCRIPTION, EXECUTION, REGISTRATION AND EXCHANGE OF NOTES 

Section 2.01. Designation and Amount. The Notes shall be designated as the “2.25% Convertible Senior Notes due
2019.” The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is initially limited to $160,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes
purchased by the Initial Purchasers pursuant to the exercise of their over-allotment option as set forth in the Purchase Agreement), subject to Section 2.10 and except for Notes authenticated and delivered upon registration or transfer of, or in
exchange for, or in lieu of other Notes to the extent expressly permitted hereunder. 
 Section 2.02. Form of
Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the respective forms set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby expressly
incorporated in and made a part of this Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 

Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the
provisions of this Indenture as may be required by the Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated
quotation system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject. 

  
 12 

 Any of the Notes may have such letters, numbers or other marks of identification and such
notations, legends or endorsements as any Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with
any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate
any special limitations or restrictions to which any particular Notes are subject. 
 Each Global Note shall represent such principal amount
of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes
represented thereby may from time to time be increased or reduced to reflect repurchases, cancellations, conversions, transfers, exchanges or issuances of additional Notes pursuant to Section 2.10 (to the extent such issuances are fungible with the
Notes represented by such Global Note for U.S. federal income tax and securities law purposes) permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented
thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with this Indenture. Payment of principal (including the Fundamental Change
Repurchase Price, if applicable) of, and accrued and unpaid interest on, a Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders eligible to receive payment is
provided for herein. 
 Section 2.03. Date and Denomination of Notes; Payments of Interest and Defaulted Amounts.
(a) The Notes shall be issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. Each Note shall be dated the date of its authentication and shall bear interest from the date
specified on the face of such Note. Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months or, in the case of a partial month, the number of days elapsed over a 30-day month. The Company shall
pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

(b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Regular
Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. The principal amount of any Note (x) in the case of any Physical Note, shall be payable at the office or
agency of the Company maintained by the Company for such purposes in the continental United States of America, which shall initially be the Corporate Trust Office and (y) in the case of any Global Note, shall be payable by wire transfer of
immediately available funds to the account of the Depositary or its nominee. The Company shall pay interest (i) on any Physical Notes (A) to Holders holding Physical Notes having an aggregate principal amount of $5,000,000 or less, by
check mailed to the Holders of these Notes at their address as it appears in the Note Register and (B) to Holders holding Physical Notes having an aggregate principal 

  
 13 

 
amount of more than $5,000,000, either by check mailed to each such Holder or, upon application by such a Holder to the Note Registrar not later than the relevant Regular Record Date, by wire
transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Note Registrar to the contrary or (ii) on any Global Note by
wire transfer of immediately available funds to the account of the Depositary or its nominee. 
 (c) Any Defaulted Amounts shall forthwith
cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes plus one percent, subject to the enforceability thereof under applicable law, from, and including, such relevant
payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: 

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective
Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the
Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 calendar days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the
same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of
the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted
Amounts which shall be not more than 15 calendar days and not less than 10 calendar days prior to the date of the proposed payment, and not less than 10 calendar days after the receipt by the Trustee of the notice of the proposed payment. The
Company shall promptly notify the Trustee of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be
delivered to each Holder not less than 10 calendar days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid
to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.03(c).

 (ii) The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the
requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after written notice given
by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

  
 14 

 Section 2.04. Execution, Authentication and Delivery of Notes. The Notes shall
be signed in the name and on behalf of the Company by the manual or facsimile signature of any Officer. 
 At any time and from time
to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in
accordance with such Company Order shall authenticate and deliver such Notes, without any further action by the Company hereunder. 
 Only
such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the Form of Note attached as Exhibit A hereto, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed
by the Trustee as provided by Section 17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company
shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture. 

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have
been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer of the Company;
and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Indenture any such person was not such an
Officer. 
 Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary.
(a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note
Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of
being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The
Company may appoint one or more co-Note Registrars in accordance with Section 4.02. 
 Upon surrender for registration of transfer of
any Note to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee, upon receipt of a Company Order and any other items required
to be delivered hereunder, shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends
as may be required by this Indenture. 
 Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate
principal amount, upon surrender of the Notes to be exchanged at any such office or 

  
 15 

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

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

None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of
(i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not
withdrawn) in accordance with Article 15. 
 All Notes issued upon any registration of transfer or exchange of Notes in accordance with this
Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. 

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the
fourth paragraph from the end of Section 2.05(c) all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. Each Global Note
shall bear the legend required on a Global Note set forth in Exhibit A hereto. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not
the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor. 

(c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any
Common Stock issued upon conversion of the Notes that is required to bear the legend set forth in Section 2.05(d), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section
2.05(c) (including those contained in the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Security, by such Holder’s
acceptance thereof, agrees to be bound by all 

  
 16 

 
such restrictions on transfer. As used in this Section 2.05(c) and Section 2.05(d), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever
of any Restricted Security. 
 Until the date (the “Resale Restriction Termination Date”) that is the later
of (1) the date that is one year after the last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and (2) such other date, if any, as may be required by
applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in Section 2.05(d),
if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be
effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice
thereof to the Trustee): 
 THE SALE OF THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), AND, ACCORDINGLY, PRIOR TO THE RESALE RESTRICTION TERMINATION DATE (AS DEFINED BELOW), THIS NOTE AND ANY SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF THIS NOTE MAY NOT BE OFFERED, RESOLD OR OTHERWISE
TRANSFERRED, EXCEPT: 
 (A) TO ENERNOC, INC. (THE “COMPANY”) OR ANY SUBSIDIARY THEREOF; 

(B) PURSUANT TO, AND IN ACCORDANCE WITH, A REGISTRATION STATEMENT THAT IS EFFECTIVE UNDER THE SECURITIES ACT AT THE TIME OF
SUCH TRANSFER; 
 (C) TO A PERSON THAT YOU REASONABLY BELIEVE TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE
144A UNDER THE SECURITIES ACT; OR 
 (D) UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT (INCLUDING, IF AVAILABLE, THE EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT). 
 THE “RESALE RESTRICTION
TERMINATION DATE” MEANS THE LATER OF: (1) THE DATE THAT IS ONE YEAR AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE NOTES OR SUCH SHORTER PERIOD OF TIME PERMITTED BY RULE 144 OR ANY SUCCESSOR PROVISION THERETO; AND (2) SUCH OTHER
DATE AS MAY BE REQUIRED BY APPLICABLE LAW. 
 WITH RESPECT TO ANY TRANSFER PURSUANT TO THE FOREGOING CLAUSE (D), PRIOR TO THE RESALE
RESTRICTION TERMINATION DATE, THE 

  
 17 

 
COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE AND MAY RELY UPON TO CONFIRM THAT SUCH
TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on
the Form of Assignment and Transfer has been checked. 
 Any Note (or security issued in exchange or substitution therefor) (i) as to
which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to, and in accordance with, a registration statement that has become effective or been declared effective under the
Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may,
upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend
required by this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the Custodian in writing to so surrender any Global Note as to which any of the conditions set forth in clause
(i) through (iii) of the immediately preceding sentence have been satisfied, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the
restrictive legend specified in this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the Resale Restriction Termination Date and promptly after a registration
statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act. 

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may not be
transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding paragraph. 

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to
act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for
Cede & Co. The Trustee shall have no liability or responsibility for the action or inaction of the Depositary or any other clearing agency. 

If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the
Global Notes and a successor depositary is not appointed 

  
 18 

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

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon
receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical
Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance
with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase. 
 None of the Company, the Trustee or any agent of the Company or the
Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. 
 (d) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued
upon conversion of a Note shall bear a legend in substantially the following form (unless such Common Stock has been transferred pursuant to, and in accordance with, a registration statement that has become effective or been declared effective under
the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has been
issued upon conversion of a Note that has transferred pursuant to, and in accordance with, a registration statement that has become effective or been declared effective under the Securities Act and that continues to be effective at the time of such
transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer
agent for the Common Stock): 
 THE SALE OF THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED
(THE “SECURITIES ACT”), AND ACCORDINGLY, PRIOR TO THE RESALE RESTRICTION TERMINATION DATE (AS DEFINED BELOW), THIS SECURITY MAY NOT BE OFFERED, RESOLD, OR OTHERWISE TRANSFERRED, EXCEPT: 

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

  
 19 

 (B) PURSUANT TO, AND IN ACCORDANCE WITH, A REGISTRATION STATEMENT THAT IS
EFFECTIVE UNDER THE SECURITIES ACT AT THE TIME OF SUCH TRANSFER; 
 (C) TO A PERSON THAT YOU REASONABLY BELIEVE TO BE A
QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT; OR 
 (D) UNDER ANY OTHER AVAILABLE
EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (INCLUDING, IF AVAILABLE, THE EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT). 

THE “RESALE RESTRICTION TERMINATION DATE” MEANS THE LATER OF: (1) THE DATE THAT IS ONE YEAR AFTER THE LAST DATE
OF ORIGINAL ISSUANCE OF THE COMPANY’S 2.25% CONVERTIBLE SENIOR NOTES DUE 2019 OR SUCH SHORTER PERIOD OF TIME PERMITTED BY RULE 144 OR ANY SUCCESSOR PROVISION THERETO; AND (2) SUCH OTHER DATE AS MAY BE REQUIRED BY APPLICABLE LAW.

 WITH RESPECT TO ANY TRANSFER PURSUANT TO THE FOREGOING CLAUSE (D), PRIOR TO THE RESALE RESTRICTION TERMINATION DATE, THE COMPANY AND
THE COMPANY’S TRANSFER AGENT RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE AND MAY RELY UPON TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 Any such Common Stock
(i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to, and in accordance with, a registration statement that has become effective or been declared
effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the
Securities Act, may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the 

  
 20 

 
Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section
2.05(d). 
 (e) Any Note that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at
any time during the three months preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities
Act in a transaction that results in such Note no longer being a “restricted security” (as defined under Rule 144). The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in
accordance with Section 2.08. 
 Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration
number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution,
and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of
the ownership thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the
receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed on the Holder by the Company, the Trustee, the Note Registrar, any co-Note Registrar or
the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the
Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required
repurchase or is about to be converted in accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or
convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable,
to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or
theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen
shall constitute an additional contractual 

  
 21 

 
obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations
set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive
with respect to the replacement, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender. 

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

Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of
payment, repurchase, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation.
All Notes delivered to the Trustee shall be canceled promptly by it in accordance with its customary procedures, and, except for Notes surrendered for registration of transfer or exchange, no Notes shall be authenticated in exchange thereof except
as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver a certificate of such disposition to the Company,
at the Company’s written request in a Company Order.  
 Section 2.09. CUSIP Numbers. The Company in issuing
the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state
that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify
the Trustee in writing of any change in the “CUSIP” numbers.  

  
 22 

 Section 2.10. Additional Notes; Repurchases. The Company may, without the consent of
the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (except for any differences in issue price and interest accrued, if any) in an
unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax and securities law purposes, such additional Notes shall have a separate
CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such
matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the
Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other
derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08, and such Notes shall
no longer be considered outstanding hereunder upon their repurchase. 
 ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officer’s
Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture and the Notes, when (a) (i) all Notes theretofore
authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in
trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d)) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with
the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or, solely to satisfy the Company’s
Conversion Obligation, cash and/or shares of Common Stock sufficient to pay all of the outstanding Notes or satisfy all outstanding conversions, as the case may be, and pay all other sums due and payable under this Indenture by the Company; and
(b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied
with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive.

PARTICULAR COVENANTS OF THE COMPANY 

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

Section 4.02. Maintenance of Office or Agency. The Company will maintain in the continental United States of America an
office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion
Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of
such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made at or
delivered to the Corporate Trust Office or the office or agency of the Trustee in the continental United States of America. 

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

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate
Trust Office as the office or agency in the continental United States of America where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase or for conversion and where notices and demands to
or upon the Company in respect of the Notes and this Indenture may be delivered. 
 Section 4.03. Appointments to Fill
Vacancies in Trustee’s Capacity. The Company, whenever necessary to avoid or fill a vacancy in the capacity of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee
hereunder. 
 Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent
other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 

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

  
 24 

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

(iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the
Trustee all sums so held in trust. 
 The Company shall, on or before each due date of the principal (including the Fundamental
Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid
interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent
by 11:00 a.m., New York City time, on such date. 
 (b) If the Company shall act as its own Paying Agent, it will, on or before each
due date of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to
pay such principal (including the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the
Company to make any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable. 

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction
and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be
held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such
sums or amounts. 
 (d) Any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such
principal (including the Fundamental Change Repurchase Price, if applicable), interest or consideration due upon conversion has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate,
or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent
with respect to such trust money and shares of Common Stock, and all 

  
 25 

 
liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, notice that such
money and shares of Common Stock remain unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money and shares of Common Stock then remaining will be
repaid or delivered to the Company. 
 Section 4.05. Existence. Subject to Article 11, the Company shall do or
cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 

Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) If, at any time, the Company is not subject to
Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the meaning of Rule
144(a)(3) under the Securities Act, upon the written request of any Holder, beneficial owner or prospective purchaser of Notes or any shares of Common Stock issuable upon the conversion of the Notes, promptly furnish such Holder, beneficial owner or
prospective purchaser the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of the Notes or such shares of Common Stock pursuant to Rule 144A, as such rule may be amended from time to
time. The Company shall take such further action as any Holder or beneficial owner of the Notes or any shares of Common Stock issuable upon conversion of the Notes may reasonably request to the extent from time to time required to enable such Holder
or beneficial owner to sell the Notes or any shares of Common Stock issuable upon conversion of the Notes in accordance with Rule 144A, as such rule may be amended from time to time. 

(b) The Company shall file with the Trustee, within 15 calendar days after the same are required to be filed with the Commission (giving
effect to any grace period provided by Rule 12b-25 under the Exchange Act or any successor rule under the Exchange Act), copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act (excluding any information, documents or reports, or portions thereof, subject to confidential treatment, and any correspondence with the Commission). Any such document or report that the Company files with the Commission via the
Commission’s EDGAR system (or any successor thereto) shall be deemed to be filed with the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system (or any successor thereto). 

(c) Delivery of the information, documents and reports described in subsection (b) above to the Trustee is for informational purposes only,
and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate) and the Trustee shall have no liability or responsibility for the filing, timeliness or content of any report or filing delivered or provided by
the Company. 

  
 26 

 (d) If, at any time during the six-month period beginning on, and including, the date that is six
months from the last date of original issuance of the Notes (such date, the “Original Issuance Date”), the Company fails to timely file any report that it is required to file with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates and Holders
that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest
on the Notes. Such Additional Interest shall accrue on the Notes at a rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is
continuing or the Notes are not otherwise freely tradable during such period by Holders other than the Company’s Affiliates and Holders that have been the Company’s Affiliates at any time during the three months immediately preceding
(without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes). As used in this Section 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to
Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act. 

(e) If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c) has not been removed, the Notes are assigned a
restricted CUSIP number or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates and Holders that were the Company’s Affiliates at any time during the three months immediately preceding (without
restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 375th calendar day after the Original Issuance Date, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum
of the principal amount of Notes outstanding until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes are assigned an unrestricted CUSIP number and the Notes are freely tradable by Holders other than
the Company’s Affiliates and Holders that were the Company’s Affiliates at any time during the three months immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes). 

(f) Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on
the Notes. 
 (g) Subject to the immediately succeeding sentence, the Additional Interest that is payable in accordance with
Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03. However, in no event shall any Additional
Interest that may accrue as a result of the Company’s failure to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to
all applicable grace periods thereunder and other than current reports on Form 8-K), as described in Section 4.06(d), together with any interest that may accrue in the event the Company elects to pay
Additional Interest in respect of an Event of Default relating to its failure to comply with its obligations as set forth under Section 6.03, accrue at a rate in excess of 0.50% per annum, regardless of the number of events or
circumstances giving rise to the requirement to pay such Additional Interest. 

  
 27 

 (h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or
Section 4.06(e), the Company shall deliver to the Trustee an Officer’s Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable.
Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly
to the Persons entitled to it, the Company shall deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment. 

Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal
of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted. 
 Section 4.08. Compliance Certificate; Statements as to
Defaults. The Company shall deliver to the Trustee within 120 calendar days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2014) an Officer’s Certificate stating (x) that in
the course of the performance by the signer of its duties as an Officer of the Company it would normally have knowledge of any Default and (y) whether the signer thereof knows of any Default that occurred during the previous year and, if so,
specifying each such Default, its status and what actions the Company is taking or proposing to take with respect thereto. 
 In
addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within 30 calendar days after obtaining knowledge of any Event of Default or Default, an Officer’s Certificate setting forth the details of such Event of
Default or Default, its status and the action that the Company is taking or proposing to take in respect thereof. 

Section 4.09. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 

ARTICLE 5 
 LISTS
OF HOLDERS AND REPORTS BY THE COMPANY AND THE TRUSTEE

Trustee, semi-annually, not more than 15 calendar days after each February 1 and August 1 in each year beginning with February 1, 2015, and at such other times  

  
 28 

 
as the Trustee may request in writing, within 30 calendar days after receipt by the Company of any such request (or such lesser time as the Trustee may reasonably request in order to enable it to
timely provide any notice to be provided by it hereunder), a list in such form as the Trustee may reasonably require of the names and addresses of the Holders as of a date not more than 15 calendar days (or such other date as the Trustee may
reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no such list need be furnished so long as the Trustee is acting as Note Registrar. 

Section 5.02. Preservation and Disclosure of Lists. The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of the Holders contained in the most recent list furnished to it as provided in Section 5.01 or maintained by the Trustee in its capacity as Note Registrar, if so acting. The Trustee
may destroy any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished. 
 ARTICLE 6

 29 

 
Significant Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or
(ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, if such default is not cured or waived, or such
acceleration is not rescinded, within 30 calendar days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in

 (h) a final judgment or judgments for the payment of $5,000,000 (or the foreign currency equivalent

custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive calendar
days. 
 Section 6.02. Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be
continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company), unless the principal of all of the Notes shall have already
become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, in each case, by notice in writing to the Company (and to the Trustee
if given by Holders), may declare 100% of the principal amount of, and accrued and unpaid interest, if any, on all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be
immediately due and payable, anything contained in this Indenture or in the Notes to the contrary notwithstanding. If an Event 

  
 30 

 
of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company occurs and is continuing, 100% of the principal amount of, and accrued and unpaid interest, if any, on, all
Notes shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of Notes. 

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall
have been so declared due and payable (or have become immediately due and payable), and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, if (1) the Company shall have
paid or deposited with the Trustee a sum sufficient to pay all matured installments of accrued and unpaid interest upon the Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on such
principal and, to the extent that such payment is enforceable under applicable law, on overdue installments of accrued and unpaid interest, at the rate borne by the Notes plus one percent at such time to the date of such payment or deposit)
and amounts due to the Trustee pursuant to Section 7.06, (2) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (3) any and all existing Events of Default under this Indenture, other
than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall not have become due by their terms, shall have been remedied or waived pursuant to Section 6.09, then and in every such case (except as provided in
the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes
and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission
and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or
shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest, if any, on, any Notes, (ii) a failure to
repurchase any Notes when required under this Indenture, or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 

Section 6.03. Additional Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the
Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall (i) for the first 180 calendar days after the occurrence of such an Event of
Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each day during such 180-calendar day period on which such an Event of
Default is continuing and (ii) for the period from, and including, the 181st calendar day after the occurrence of such an Event of Default to, and including, the 270th calendar day after the occurrence of such an Event of Default, consist
exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding for each day during such additional 90-calendar day period on which such an Event of Default is
continuing. Subject to the last paragraph of this Section 6.03, Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or

  
 31 

 
Section 4.06(e). If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 271st calendar
day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) is not cured or waived prior to such 271st calendar day), the Notes shall be immediately
subject to acceleration as provided in Section 6.02. The provisions of this Section 6.03 will not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. In the event the Company does not elect to pay
Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided
in Section 6.02. 
 In order to elect to pay Additional Interest as the sole remedy during the first 270 calendar days after the occurrence
of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent (if other than the Trustee) of such election prior to the beginning of such 270-calendar day
period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 

In no event shall Additional Interest payable in the event the Company elects to pay Additional Interest in respect of an Event of Default
relating to its failure to comply with its obligations under Section 4.06(b) as set forth in this Section 6.03, together with any interest that may accrue as a result of the Company’s failure to timely file any document or report that it is
required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than current reports on Form 8-K), as described in Section
4.06(d), accrue at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. 

Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section
6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any
overdue principal and interest, if any, at the rate borne by the Notes plus one percent at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee hereunder. If the Company shall
fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or
final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the
Notes, wherever situated. 
 In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the
Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Company or such other obligor, the property of the Company or such 

  
 32 

 
other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other
obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions
of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in
case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their
property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee hereunder; and any receiver, assignee or trustee in
bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee hereunder,
incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall
be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the
Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or
abandoned because of any waiver pursuant to 

  
 33 

 
Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the
Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall continue
as though no such proceeding had been instituted. 
 Section 6.05. Application of Monies Collected by Trustee. Any monies
collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and
stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the payment of all
amounts due the Trustee (in any capacity) hereunder; 
 Second, in case the principal of the outstanding Notes shall not have become
due and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent
that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, plus one percent, such payments to be made ratably to the Persons entitled thereto; 

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment
of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal
and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time plus one percent, and in case such monies shall be insufficient to pay in full the
whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of principal over
interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change
Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and 
 Fourth, to the payment of the remainder,
if any, to the Company. 
 Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal
(including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder shall have any right by virtue of or by availing of any
provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any
other remedy hereunder, unless: 
 (a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of
the continuance thereof, as herein provided; 

  
 34 

 (b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall
have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 
 (c) such
Holders shall have offered to the Trustee such security or indemnity, in each case, reasonably satisfactory to it against all losses and expenses to be incurred therein or thereby; 

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

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that
no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and
enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any Holder to receive payment or delivery,
as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the
respective due dates expressed or provided for in such Note or in this Indenture, or to bring suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired
or affected without the consent of such Holder. 
 Section 6.07. Proceedings by Trustee. In case of an Event of Default, the
Trustee may proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding
in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in
the Trustee by this Indenture or by law. 
 Section 6.08. Remedies Cumulative and Continuing. Except as provided in the last
paragraph of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to 

  
 35 

 
the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes,
by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power
accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power
and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 

Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. Subject to the Trustee’s right
to request security or indemnity from the relevant Holders as described herein, the Holders of a majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to
direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes; provided, however, that (a) such direction
shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that
it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with
Section 8.04 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including
any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of
the Notes, (iii) a failure by the Company to repurchase any Notes when required under this Indenture or (iv) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of
each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and
this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

Section 6.10. Notice of Defaults. The Trustee shall, within 90 calendar days after it receives notice of the occurrence and
continuance of a Default of which a Responsible Officer has actual knowledge, deliver to all Holders notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice;
provided that, except in the case of a Default in the payment of the principal of (including the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery
of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 

  
 36 

 Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree,
and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for
any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees
and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law)
shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section
8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price, if applicable) on or
after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions of Article 14.

transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without gross negligence, willful misconduct or bad faith on
the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this Indenture or in any other capacity
hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust
herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The obligation of the
Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be
unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee. 

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating
agent incur expenses or render services after an Event of Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy,
insolvency or similar laws.

provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter
(unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, willful misconduct and bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an
Officer’s Certificate delivered to the Trustee, and such Officer’s Certificate, in the absence of gross negligence, willful misconduct and bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken or
omitted by it under the provisions of this Indenture upon the faith thereof. 
 Section 7.08. Eligibility of
Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of
at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 7.09. Resignation or
Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by delivering notice thereof to the Holders. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee
shall have been so appointed and have accepted appointment within 60 calendar days after the delivery of such notice of resignation to the Holders, the resigning Trustee may, at the Company’s expense, upon ten Business Days’ notice to the
Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may,
subject to the provisions of Section 6.11, on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee. 
 (b) In case at any time any of the following shall occur: 

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign after
written request therefor by the Company or by any such Holder, or 
 (ii) the Trustee shall become incapable of acting, or
shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, 

  
 42 

 then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.11, any Holder
who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of
the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

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

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 7.09
shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. The Trustee shall have no liability or responsibility for the action or inaction of any successor trustee. 

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

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the
written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee hereunder 

  
 43 

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

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

 ARTICLE 8 

CONCERNING THE HOLDERS 

Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of
the aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders.
Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining Holders
entitled to take such action. The record date if one is selected shall be not more than fifteen calendar days prior to the date of commencement of solicitation of such action. 

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

Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any
Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding
any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03) accrued and unpaid interest
on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments or
deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares
deliverable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the
consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this
Indenture. 
 Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the requisite
aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any 

  
 45 

 
Subsidiary thereof or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary thereof shall be disregarded
and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that
a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of
the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with
the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the
Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be
entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the
evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as
concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution
therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof. 

ARTICLE 9

Holders, as the case may be. Notice of every meeting of the Holders, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting and the establishment of any record date pursuant to
Section 8.01, shall be delivered to Holders of such Notes. Such notice shall also be mailed to the Company. Such notices shall be delivered or mailed, as the case may be, not less than 20 nor more than 90 calendar days prior to the date fixed for

 Any meeting of Holders shall be valid without notice if the Holders of all Notes then outstanding are present in
person or by proxy or if notice is waived before or after the meeting by the Holders of all Notes then outstanding, and if the Company and the Trustee are either present by duly authorized representatives or have, before or after the meeting, waived
notice.

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

Section 9.04. Qualifications for Voting. To be entitled to vote at any meeting of Holders a Person shall (a) be a

and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 

  
 47 

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

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

written reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of
the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed or delivered, as the case may
be, as provided in Section 9.02. The record shall show the aggregate principal amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the
meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 

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

Section 9.07. No Delay of Rights by Meeting. Nothing contained in this Article 9 shall be deemed or construed to authorize
or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the
Holders under any of the provisions of this Indenture or of the Notes.

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

Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8) of the Holders of
at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and

such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall deliver to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all
the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 

  
 50 

 Section 10.03. Effect of Supplemental Indentures. Upon the execution of any
supplemental indenture pursuant to the provisions of this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under
this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental
indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

consolidated properties or assets of the Company and its Subsidiaries, taken as a whole, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may

issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the
execution hereof. In the event of any such consolidation, merger, sale, conveyance, assignment, transfer or other disposition (but not in the case of a lease), upon compliance with this Article 11 the Person named as the “Company” in
the first paragraph of this Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such
Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes. 

In case of any such consolidation, merger, sale, conveyance, assignment, transfer, lease or other disposition, such changes in phraseology and
form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

CONVERSION OF NOTES 

Section 14.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 14, each
Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the
conditions described in Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding February 15, 2019 under the circumstances and during the periods set forth in Section 14.01(b), and
(ii) regardless of the conditions described in Section 14.01(b), on or after February 15, 2019 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial
conversion rate of 36.0933 shares of Common Stock (subject to adjustment as provided in this Article 14, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement
provisions of Section 14.02, the “Conversion Obligation”). 
 (b) (i) Prior to the close of
business on the Business Day immediately preceding February 15, 2019, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day period

unless the Company has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per
$1,000 principal amount of Notes) unless a Holder of at least $1,000,000 aggregate principal amount of Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the
product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent in writing (if other than the Company) to determine, or if the Company is acting as Bid
Solicitation Agent, the Company shall determine, 

  
 53 

 
the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater
than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not, when it is required to, instruct the Bid
Solicitation Agent to obtain bids, or if the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent and the Company
fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of
the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met on any Trading Day, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other
than the Trustee) in writing on such Trading Day. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last
Reported Sale Price of the Common Stock and the Conversion Rate for such Trading Day, the Company shall promptly so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing that the Trading Price
condition set forth above is no longer met and thereafter neither the Company nor the Bid Solicitation Agent, as applicable, shall be required to measure the Trading Price again until a new request is made as provided in this subsection (b)(i). 

(ii) If, prior to the close of business on the Business Day immediately preceding February 15, 2019, the Company elects
to: 
 (A) issue to all or substantially all holders of the Common Stock any rights, options or warrants (other than in
connection with a shareholder rights plan prior to separation of the relevant rights) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common
Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such
issuance; or 
 (B) distribute to all or substantially all holders of the Common Stock the Company’s assets, securities
or rights, options or warrants to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day
preceding the date of announcement for such distribution, 
 then, in either case, the Company shall notify all Holders, the Trustee and the Conversion
Agent (if other than the Trustee) at least 70 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, a Holder may surrender all or any portion of its Notes for conversion at
any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not
take place, in each case, even if the Notes are not otherwise convertible at such time. 

  
 54 

 (iii) If a transaction or event that constitutes a Fundamental Change or a
Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding February 15, 2019, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section
15.02, or if the Company is a party to a Specified Corporate Event that occurs prior to the close of business on the Business Day immediately preceding February 15, 2019, all or any portion of a Holder’s Notes may be surrendered for
conversion at any time from or after the date that is 70 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after the Company gives notice of such transaction) until 35 Trading Days
after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other
than the Trustee) (i) at least 70 Scheduled Trading Days prior to the anticipated effective date of such transaction or (ii) if the Company has not publicly announced such transaction at least 70 Scheduled Trading Days prior to the
anticipated effective date of such transaction, within one Business Day of the date the Company publicly announces such transaction, but in no event later than the actual effective date of such transaction. 

(iv) Prior to the close of business on the Business Day immediately preceding February 15, 2019, a Holder may surrender
all or any portion of its Notes for conversion at any time during any fiscal quarter commencing after the fiscal quarter ending on September 30, 2014 (and only during such fiscal quarter), if the Last Reported Sale Price of the Common Stock for
at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding fiscal quarter is greater than or equal to 130% of the Conversion Price on each
applicable Trading Day. The Company shall determine at the beginning of each fiscal quarter commencing after September 30, 2014 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the
Conversion Agent (if other than the Trustee) and the Trustee if the Notes become convertible in accordance with this clause (iv). 

Section 14.02. Conversion Procedure; Settlement Upon Conversion. 

(a) Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, if the Company has not received
Stockholder Approval prior to (x) in respect of a conversion of a Note for which the relevant Conversion Date occurs prior to February 15, 2019, the relevant Conversion Date and (y) in respect of a conversion of a Note for which the
relevant Conversion Date occurs on or after February 15, 2019, February 15, 2019 (the date set forth in clause (x) or clause (y), as the case may be, the “Stockholder Approval Deadline”), the Company shall
satisfy its Conversion Obligation in respect of such Note (in the case of clause (x)) or in respect of all Notes for which the relevant Conversion Date occurs on or after February 15, 2019 (in the case of clause (y)) by Physical Settlement.
Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, if the Company has received Stockholder Approval prior to the relevant Stockholder Approval Deadline, the Company shall pay or deliver, as the case
may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of 

  
 55 

 
Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Physical
Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02
(“Combination Settlement”), at its election, as set forth in this Section 14.02. If the Company receives Stockholder Approval on any day, it shall so notify Holders, the Trustee and the Conversion Agent (if other than the Trustee)
in writing within one Business Day. 
 (i) All conversions for which the relevant Conversion Date occurs during the period
from, and including, February 15, 2019 to, and including, the second Scheduled Trading Day immediately preceding the Maturity Date, shall be settled using the same Settlement Method. 

(ii) Except for any conversions described in Section 14.02(a)(i), the Company shall use the same Settlement Method for all
conversions with the same Conversion Date, but (unless the Company has not received Stockholder Approval prior to the relevant Stockholder Approval Deadline, in which case the Company shall be required to settle the relevant conversion by Physical
Settlement), the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates. 

(iii) Following the Company’s receipt of Stockholder Approval, if, in respect of any Conversion Date (or the period from,
and including, February 15, 2019 to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement
Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to converting Holders no later than the close of business on the second Trading Day immediately
following the relevant Conversion Date (or, in the case of any conversions occurring during the period from, and including, February 15, 2019 to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date,
no later than the close of business on February 15, 2019). If (a) the Company has received Stockholder Approval prior to the relevant Stockholder Approval Deadline and (b) the Company does not elect a Settlement Method prior to the deadline set
forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation,
and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement
Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If, in respect of a conversion following the Company’s receipt of Stockholder Approval, the Company delivers a Settlement Notice electing (or is deemed to
have elected) Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of
Notes shall be deemed to be $1,000. If the Company has obtained Stockholder Approval, the Company may at any time prior to February 15, 2019 irrevocably elect to settle all conversions through Combination Settlement with a Specified Dollar
Amount the Company elects. 

  
 56 

 (iv) With respect to any conversion, the cash, shares of Common Stock or
combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 

(A) if the Company has not received Stockholder Approval prior to the relevant Stockholder Approval Deadline or if the Company
elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Notes being converted a number of shares of Common
Stock equal to the Conversion Rate in effect on the Conversion Date; 
 (B) if the Company elects to satisfy its Conversion
Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for
each of the 60 consecutive Trading Days during the related Observation Period; and 
 (C) if the Company elects (or is deemed
to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement
Amount equal to the sum of the Daily Settlement Amounts for each of the 60 consecutive Trading Days during the relevant Observation Period. 

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

(b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall
(i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, (1) pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set
forth in Section 14.02(h) and (2) pay all transfer and similar taxes as set forth in Section 14.02(d) and Section 14.02(e) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the
Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and 

  
 57 

 
state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common
Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the
Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents, (4) if required, pay all transfer and similar taxes as set forth in Section 14.02(d) and Section 14.02(e) and (5) if required, pay funds equal
to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14
on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and
has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03. 
 If more than one Note shall be
surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted
thereby) so surrendered. 
 (c) A Note shall be deemed to have been converted immediately prior to the close of business on the date
(the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 14.03(b) and Section 14.07(a), the Company shall pay or deliver, as the case may be, the
consideration due in respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects, or is required, to satisfy its Conversion Obligation by Physical Settlement, or on the
third Business Day immediately following the last Trading Day of the Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and
deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in
satisfaction of the Company’s Conversion Obligation. 
 (d) In case any Note shall be surrendered for partial conversion, the
Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted
portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar
governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such
conversion. 
 (e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax
due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests any such shares to be issued in a 

  
 58 

 
name other than the Holder’s name, in which case the Holder must pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being
issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence. 

(f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of
any Note as provided in this Article 14. 
 (g) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at
the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent
other than the Trustee. 
 (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if
any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but excluding, the
relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a
combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular
Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered
for conversion during the period beginning after the close of business on any Regular Record Date and ending at the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest
payable on the Notes so converted; provided that no such payment shall be required (1) for Notes surrendered for conversion after the close of business on the Regular Record Date immediately preceding the Maturity Date; (2) if the
Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any Defaulted Amounts, if
any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date and any Fundamental Change Repurchase
Date described in clause (2) of the immediately preceding sentence shall receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been converted or repurchased,
as applicable, following such Regular Record Date. 
 (i) The Person in whose name the shares of Common Stock shall be issuable upon
conversion shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects, or is required, to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day
of the relevant Observation Period (if the Company satisfies the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for
conversion. 

  
 59 

 (j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes
and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last
Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has received Stockholder Approval prior to the relevant Stockholder Approval Deadline and elected
Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after
such computation shall be paid in cash. 
 Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in
Connection with Make-Whole Fundamental Changes. (a) If, prior to the Maturity Date, a Make-Whole Fundamental Change Effective Date occurs and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the
Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A
conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Make-Whole Fundamental
Change Effective Date up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso
in clause (b) of the definition thereof, the 35th Trading Day immediately following the Make-Whole Fundamental Change Effective Date). 

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to Section 14.01(b)(iii), the
Company shall satisfy its Conversion Obligation by Physical Settlement or, if the Company has received Stockholder Approval prior to the relevant Stockholder Approval Deadline, the Company shall, at its option, satisfy the related Conversion
Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the
definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Make-Whole Fundamental Change Effective Date, the Conversion Obligation
shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares),
multiplied by such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes of any Make-Whole
Fundamental Change Effective Date no later than five Business Days after such Make-Whole Fundamental Change Effective Date. 

  
 60 

 (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased
shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Make-Whole Fundamental Change Effective Date”) and the price paid (or deemed to be
paid) per share of the Common Stock in the Make-Whole Fundamental Change (the “Stock Price”). If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in
clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. In the case of any other Make-Whole Fundamental Change, the Stock Price shall be the average of the Last Reported Sale Prices of the
Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Make-Whole Fundamental Change Effective Date. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good
faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date of the event occurs during
such five consecutive Trading Day period. 
 (d) The Stock Prices set forth in the column headings of the table below shall be adjusted as
of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the
Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the
same manner and at the same time as the Conversion Rate as set forth in Section 14.04. 
 (e) The following table sets forth the number
of Additional Shares to be added to the Conversion Rate per $1,000 principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Make-Whole Fundamental Change Effective Date set forth below: 

 

																																																	
	 	 	Stock Price

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

  
 61 

 (ii) if the Stock Price is greater than $150.00 per share (subject to adjustment
in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii) if the Stock Price is less than $19.79 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 50.5305 shares of Common Stock, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 
 (f) Nothing in this Section 14.03 shall prevent an
adjustment to the Conversion Rate pursuant to Section 14.04 in respect of a Make-Whole Fundamental Change. 
 Section 14.04.
Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes
participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any
of the transactions described in this Section 14.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes
held by such Holder. 
 (a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on shares of the Common
Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 
  

 
  

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

  
 62 

 Any adjustment made under this Section 14.04(a) shall become effective immediately after the open of business on
the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section
14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared. 
 (b) If the Company issues to all or substantially all holders of the
Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than
the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be
increased based on the following formula: 
  
 

 
  

					
	where,
			
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive
Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants are
issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the
Conversion 

  
 63 

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

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights,
options or warrants to acquire shares of its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to
Section 14.04(a) or Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 14.04(d), (iii) conversion of the Common Stock into, or exchange of the Common Stock
for, in each case, Reference Property pursuant to a transaction described in Section 14.07, (iv) except as otherwise provided in Section 14.11, rights issued pursuant to a shareholder rights plan adopted by the Company and (v) Spin-Offs as
to which the provisions set forth below in this Section 14.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire shares of Capital Stock or other
securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 
  

 
  

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

  
 64 

 Any increase made under the portion of this Section 14.04(c) above shall become effective immediately after the
open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had not been declared. 

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as
holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record
Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it shall in
doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such distribution. 
 With respect to an adjustment pursuant to this Section 14.04(c) where there has been a payment of
a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or
admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
  

 
  

					
	where,
			
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the shares of Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition
of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of
the Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

  
 65 

 The increase to the Conversion Rate under the preceding paragraph shall be determined on the last
Trading Day of the Valuation Period, but shall be given effect at the open of business on the Ex-Dividend Date for such Spin-Off. Notwithstanding the foregoing, in respect of any conversion of Notes during the Valuation Period, references in the
portion of this Section 14.04(c) related to Spin-Offs with respect to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to,
but excluding, the Conversion Date in determining the Conversion Rate. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion of Notes, references
in the preceding paragraph to 10 consecutive Trading Days will be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the
Spin-Off to, and including, the last Trading Day of such Observation Period. If such Spin-Off does not occur, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared,
effective as of the date on which the Board of Directors determines not to consummate such Spin-Off. 
 For purposes of this Section
14.04(c) (and subject in all respect to Section 14.11), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including
Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the
Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Conversion
Rate under this Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the
Conversion Rate shall be made under this Section 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of
which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and
Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In
addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes
of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by
any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to
such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to 

  
 66 

 
the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options
or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated (or deemed to have expired or been terminated
pursuant to the immediately preceding sentence) without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued (to the extent any adjustment to the Conversion Rate was
made in connection with such issuance). 
 For purposes of Section 14.04(a), Section 14.04(b) and this Section 14.04(c), if any dividend or
distribution to which this Section 14.04(c) is applicable also includes one or both of: 
 (A) a dividend or distribution of shares of
Common Stock to which Section 14.04(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend or distribution of
rights, options or warrants to which Section 14.04(b) is applicable (the “Clause B Distribution”), 
 then, in either case, (1) such
dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any
Conversion Rate adjustment required by this Section 14.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C
Distribution and any Conversion Rate adjustment required by Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A
Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be
“outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within
the meaning of Section 14.04(b). 
 (d) If any cash dividend or distribution is made to all or substantially all holders of the Common
Stock, the Conversion Rate shall be adjusted based on the following formula: 
  
 

 
  

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

  
 67 

					
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

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

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer by the Company or any of its
Subsidiaries for the Common Stock, and the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on
which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  

 
  

					
	where,	  		  	
			
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the time such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such
tender or exchange offer);
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after the time such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or
exchange offer); and
			
	SP'	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

  
 68 

 The increase to the Conversion Rate under this Section 14.04(e) shall be determined at the close
of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires, but shall be given effect at the open of business on the Trading Day next succeeding the date
such tender or exchange offer expires. Notwithstanding the foregoing, in respect of any conversion of Notes within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or
exchange offer, references in this Section 14.04(e) with respect to 10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and the
Conversion Date in determining the Conversion Rate. In addition, if the Trading Day next succeeding the expiration date for such tender or exchange offer is less than 10 Trading Days prior to, and including, the end of the Observation Period (if
applicable) in respect of any conversion of Notes, references in the preceding paragraph to 10 consecutive Trading Days shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have
elapsed from, and including, the Trading Day next succeeding the expiration date for such tender or exchange offer to, and including, the last Trading Day of such Observation Period. For the avoidance of doubt, no adjustment pursuant to this Section
14.04(e) shall be made if such adjustment would result in a decrease in the Conversion Rate. 
 If the Company is obligated to purchase
shares of the Common Stock pursuant to any such tender or exchange offer described in this Section 14.04(e) but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the applicable
Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that have been effected. 

(f) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes
effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related
Conversion Date as described under Section 14.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, the Conversion Rate adjustment relating to
such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend,
distribution or other event giving rise to such adjustment. 
 (g) Except as stated herein, the Company shall not adjust the Conversion Rate
for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. 

  
 69 

 (h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this
Section 14.04, and to the extent permitted by applicable law and subject to the applicable listing standards of The NASDAQ Global Select Market (or of any other exchange on which any of the Company’s securities are then listed), the Company
from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by
applicable law and subject to the applicable listing standards of The NASDAQ Global Select Market (or of any other exchange on which any of the Company’s securities are then listed), the Company may (but is not required to) increase the
Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or
similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note a notice of the increase at least 15 calendar days prior to the date the increased
Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

(i) Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be adjusted: 

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

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

(iii) except as set forth in Section 14.04(b) or Section 14.04(c), upon the issuance of any shares of the Common Stock pursuant
to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection; 

(iv) upon the repurchase of any shares of the Common Stock pursuant to an open-market share repurchase program or other
buy-back transaction that is not a tender offer or exchange offer of the nature described in Section 14.04(e); 
 (v) solely
for a change in the par value (or lack of par value) of the Common Stock; or 
 (vi) for accrued and unpaid interest, if any.

  
 70 

 (j) All calculations and other determinations under this Article 14 shall be made by the Company
and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. The Company shall not adjust the Conversion Rate pursuant to clauses (a) through (e) of this Section 14.04 unless the adjustment would result in a change of at least
1% in the then effective Conversion Rate. However, the Company shall carry forward any adjustment to the Conversion Rate that the Company would otherwise have to make and take that adjustment into account in any subsequent adjustment.
Notwithstanding the foregoing, all such carried-forward adjustments shall be made (i) in connection with any subsequent adjustment to the Conversion Rate of at least 1% and (ii) (x) on the Conversion Date for any Notes (in the case of
Physical Settlement) or (y) on each Trading Day of any Observation Period (in the case of Cash Settlement or Combination Settlement). 

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if
not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly
after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall deliver such notice of such
adjustment of the Conversion Rate to each Holder. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

(l) For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock
held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. 
 (m) If, in the case of any conversion of a Note to which Combination
Settlement applies, on any Trading Day during the Observation Period for such Note, shares of Common Stock are deliverable as part of the Daily Settlement Amount for such Trading Day, and 

(i) the Ex-Dividend Date for any issuance, dividend or distribution, the Effective Date for any share split or combination or
the expiration date for any tender offer or exchange offer by the Company (or, in the case of a tender offer or exchange offer, by one of the Company’s Subsidiaries) that, in each case, would require an adjustment to the Conversion Rate under
clauses (a) through (e) of this Section 14.04 occurs prior to the Company’s delivery of such shares of Common Stock to the converting Holder; 

(ii) the applicable Conversion Rate for such Trading Day will not reflect such adjustment; and 

(iii) the shares of Common Stock that the Company will deliver to the converting Holder with respect to such Trading Day are
not entitled to participate in the 

  
 71 

 
relevant event (because the converting Holder is not treated as the holder of such shares of Common Stock on the related Ex-Dividend Date, Effective Date, expiration date or otherwise), 

then the Company shall adjust the number of shares that the Company delivers to such Holder as part of the Daily Settlement Amount for such Trading Day in a
manner that the Board of Directors determines appropriately reflects the relevant issuance, dividend, distribution, transaction or event. 

Section 14.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported
Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and, if applicable, the period for determining the Stock Price for purposes of a Make-Whole
Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend
Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

 Section 14.06. Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but
unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming that at the time of computation of such number of shares, all
such Notes would be converted by a single Holder and that Physical Settlement were applicable). 
 Section 14.07. Effect of
Recapitalizations, Reclassifications and Changes of the Common Stock.  
 (a) In the case of: 

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

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

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including
cash or any combination thereof) (any such event, a “Specified Corporate Event”), then the Company or the successor or acquiring corporation, as the case may be, shall execute with the Trustee a supplemental indenture permitted
under Section 10.01(j) providing that, at and after the effective time of such Specified 

  
 72 

 
Corporate Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock,
other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Specified Corporate Event would have owned or been
entitled to receive (without giving effect to any dissenters’ rights) (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one
share of Common Stock is entitled to receive) upon the occurrence of such Specified Corporate Event; provided, however, that at and after the effective time of the Specified Corporate Event, (A) the Company or the successor or
acquiring corporation, as the case may be, shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 14.02, if the Company has received
Stockholder Approval prior to the relevant Stockholder Approval Deadline and (B) (x) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in cash, (y) any shares of
Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of
Common Stock would have received in such Specified Corporate Event and (z) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 

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

Such supplemental indenture described in the second immediately preceding paragraph shall provide for (x) anti-dilution adjustments that
shall be as nearly equivalent as practicable to the adjustments provided for in this Article 14, with respect to any Reference Property consisting of shares of Common Equity, and (y) with respect to any other Reference Property, such
adjustments (if any) that the Board of Directors determines in good faith are appropriate. If, in the case of any Specified Corporate Event, the Reference Property includes shares of stock, 

  
 73 

 
securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Specified Corporate
Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by
reason of the foregoing, including the provisions providing for the repurchase rights set forth in Article 15. 
 (b) When the Company
executes a supplemental indenture pursuant to subsection (a) of this Section 14.07, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or
property or asset that will comprise a unit of Reference Property after any such Specified Corporate Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice
thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be delivered to each Holder within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture. 
 (c) The Company shall not become a party to any Specified Corporate Event unless its terms are
consistent with this Section 14.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into shares of Common Stock or, following receipt of Stockholder Approval, cash, shares of Common Stock or a
combination of cash and shares of Common Stock, as applicable, all as set forth in Section 14.01 and Section 14.02, prior to the effective date of such Specified Corporate Event. 

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

Section 14.08. Certain Covenants. (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes
will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 
 (b)
The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares of Common
Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be. 

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

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

  
 74 

 
or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value
(or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with
respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the
surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained herein. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent
shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or amount of shares of stock or securities or property
(including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any
independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution
of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for conversion
or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the
Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in
Section 14.01(b). 
 Section 14.10. Notice to Holders Prior to Certain Actions. In case of any: 

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 14.04 or
Section 14.11; 
 (b) Specified Corporate Event; or 

(c) voluntary or involuntary dissolution, liquidation or winding-up of the Company; 

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed
with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder, as promptly as possible but in any event at least 10 calendar days prior to the applicable date hereinafter specified, a notice stating
(i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the
purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Specified Corporate Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is
expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Specified 

  
 75 

 
Corporate Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its
Subsidiaries, Specified Corporate Event, dissolution, liquidation or winding-up. 
 Section 14.11. Shareholder Rights Plans. If
the Company has a shareholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates
representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time. However, if, prior to any
conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed
to all or substantially all holders of the Common Stock Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

ARTICLE 15 

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

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time
prior to the Maturity Date, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal amount thereof that is equal to $1,000 or an
integral multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company
Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”),
unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid
interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15. 

(b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon: 

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

  
 76 

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

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

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

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

 (iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this
Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate
Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change
Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03. 

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of
withdrawal thereof. 
 (c) On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the
Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a written notice (the “Fundamental Change Company Notice”) of the occurrence of the
Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in
accordance with the applicable procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general
circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 

(i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

  
 77 

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

(v) the Fundamental Change Repurchase Date; 

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

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

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

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02. 
 At the Company’s request, the
Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

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

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

  
 78 

 (ii) if Physical Notes have been issued, the certificate number(s) of the Note(s)
in respect of which such notice of withdrawal is being submitted, and 
 (iii) the principal amount, if any, of such Note
that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 

provided, however, that if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary. 

Section 15.04. Deposit of Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying
Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an
amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for
Notes surrendered for repurchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date
(provided the Holder has satisfied the conditions in Section 15.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner
required by Section 15.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire
transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change
Repurchase Price. 
 (b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent
appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been properly surrendered for
repurchase and not validly withdrawn in accordance with Section 15.03, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the
Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price and, if the Fundamental Change Repurchase
Date falls after a Regular Record Date but on or prior to the related Interest Payment Date, the right of the Holder of record on such Regular Record Date to receive the related interest payment). 

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 15.02, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered. 

  
 79 

 Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In
connection with any repurchase offer pursuant to a Fundamental Change Repurchase Notice, the Company will, if required: 
 (a) comply with
the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable; 
 (b) file a
Schedule TO or any other required schedule under the Exchange Act; and 
 (c) otherwise comply with all federal and state securities laws in
connection with any offer by the Company to repurchase the Notes; 
 in each case, so as to permit the rights and obligations under this Article 15 to be
exercised in the time and in the manner specified in this Article 15. 
 ARTICLE 16

 The Trustee, by notice to the Company, may designate additional or different addresses for

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to

Notwithstanding any other provision of this Indenture or any Note, where this Indenture or any Note provides for notice of any event
(including any notice of repurchase) to a Holder (whether by mail or otherwise), such notice shall be sufficiently given (in the case of a Global Note) if given to the Depositary (or its designee) pursuant to the standing instructions from the

Section 17.10. Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its behalf
and subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Section 2.04, Section 2.05, Section 2.06, Section 2.07, Section
10.04 and Section 15.04 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes. For all purposes of this Indenture, the
authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the Trustee by an authenticating
agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant to Section
7.08. 
 Any corporation or other entity into which any authenticating agent may be merged or converted or with which it may be
consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity succeeding to the corporate trust business of any
authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this Section 17.10, without the execution or filing of any paper or any further act on the
part of the parties hereto or the authenticating agent or such successor corporation or other entity. 
 Any authenticating agent may at any
time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the
Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be
the Trustee), shall give written notice of such appointment to the Company and shall mail notice of such appointment to all Holders as the names and addresses of such Holders appear on the Note Register. 

The Company agrees to pay to the authenticating agent from time to time reasonable compensation for its services although the Company may
terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 
 The provisions of Section 7.02, Section
7.03, Section 7.04, Section 8.03 and this Section 17.10 shall be applicable to any authenticating agent. 
 If an authenticating agent is
appointed pursuant to this Section 17.10, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 

 

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

  

			
	By:	 	  

			
	 Authorized Signatory

 Section 17.11. Execution in Counterparts. This Indenture may be executed in any
number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall
constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their
original signatures for all purposes. 
 Section 17.12. Severability. In the event any provision of this Indenture or in the
Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired. 

Section 17.13. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

Section 17.14. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance
of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or
natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that are consistent with
accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

 [FORM OF REVERSE OF NOTE] 

EnerNOC, Inc. 
 2.25% Convertible
Senior Note due 2019 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.25% Convertible Senior
Notes due 2019 (the “Notes”), limited to the aggregate principal amount of $160,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Initial Purchasers pursuant to the
exercise of their over-allotment option as set forth in the Purchase Agreement) all issued or to be issued under and pursuant to an Indenture dated as of August 18, 2014 (the “Indenture”), between the Company and Wells Fargo
Bank, National Association (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of
the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this
Note shall have the respective meanings set forth in the Indenture. 
 In case certain Events of Default shall have occurred and be
continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. 
 Subject to the terms and
conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the
Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

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

  
 A-6 

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

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

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

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