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 the 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

 (b) The Person in whose name any Note (or its Predecessor Note) is registered on the Register at
the Close of Business (whether or not such day is a Business Day) on any Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the
office or agency of the Company maintained by the Company for such purposes which shall initially be the Corporate Trust Office, or any other office or agency located in the United States of America so designated by the Company. 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 Register and
(B) to Holders holding Physical Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to such Holders or, upon written application by such a Holder to the 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 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 in accordance with Applicable Procedures. 

(c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum
at the rate borne by the Notes, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election
in each case, as provided in clause (i) or (ii) below: 
 (i) The Company may elect to make payment of any
Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the Close of Business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following
manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 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 in writing of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Amounts and the special record date therefor to be sent to each Holder at its address as it appears in the Register, 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 sent, 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). 

  
 13 








 (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. 

Notwithstanding anything to the contrary in the Indenture of the Notes, this Section 2.03(c) shall apply to the Notes in lieu of
Section 307(b) of the Base Indenture. 
 Section 2.04 Execution, Authentication and Delivery of Notes. At any time and from time
to time after the execution and delivery of this Supplemental 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.

authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually by an authorized officer of the Trustee (or an authenticating agent appointed by the Trustee in accordance with the
Indenture), shall be entitled to the benefits of the 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 the 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 by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated (upon receipt of a Company Order) 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 Supplemental
Indenture or the Base Indenture any such Person was not such an Officer.

Restrictions on Transfer; Depositary. (a) The Company shall cause to be kept at the office of the Registrar a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to

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 the 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 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, upon receipt of a Company Order, 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 Registrar or any co-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 by the Company, the Trustee, the Registrar, any co-Registrar or any 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 or other similar governmental charge required by law or

any Note, surrendered for repurchase (and not withdrawn) in accordance with Article XIII. 
 All Notes issued upon any registration of
transfer or exchange of Notes in accordance with the Indenture shall be the valid and binding obligations of the Company, evidencing the same debt, and entitled to the same benefits under the Indenture as the Notes surrendered upon such registration
of transfer or exchange. 
 Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 2.05(a) shall apply to
the Notes in lieu of Section 305 of the Base Indenture. 
 (b) So long as the Notes are eligible for book-entry settlement with the
Depositary, unless otherwise required by law, subject to the fifth paragraph of this Section 2.05(b) all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the
Depositary or a nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in
accordance with the Indenture and the procedures of the Depositary therefor. 

  
 15 








 Notwithstanding anything to the contrary in the Indenture or the Notes, a Global Note may not be
transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner)
by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.05(b). 

The Depositary shall be a clearing agency registered under the Exchange Act. The Company appoints DTC to act as initial Depositary with
respect to each Global Note. Each Note to be issued on the date hereof shall initially be issued in the form of one or more Global Notes, and each such 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. Neither the Trustee nor any agent shall have any responsibility or liability for any actions taken or not taken by the Depositary. 

Transfers and exchanges of the Notes will be effected through the Depositary in accordance with the Applicable Procedures. 

Unless the Company and the beneficial owner of the relevant Note agree otherwise, if, and only if, (i) the Depositary notifies the
Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 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 issued as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the
case of clause (iii), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii),
Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the
Global Notes to the Trustee such Global Notes shall be canceled. 
 Physical Notes issued in exchange for all or a part of the Global Note
pursuant to this Section 2.05(b) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing.
Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

  
 16 








 At such time as all interests in a Global Note have been converted, canceled, repurchased or
transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest
in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal
amount of such Global Note shall, in accordance with standing procedures and existing instructions between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on the Schedule
of Exchanges of such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 

None of the Company, the Trustee, nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the
records of the Depositary 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. 

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
the Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Notes) other than to require delivery of
such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, the Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements of the Indenture. 
 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 by Company Order, the Trustee or an authenticating agent appointed by the Trustee shall, upon receipt of a Company Order, 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, the Registrar, 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 upon
receipt of a Company Order any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the
Company, the Trustee, the Registrar, any co-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 

  
 17 








 
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 XII shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the
payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and,
if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of
destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set
forth in) the Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with
respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding (to the extent prohibited by the same) any law or statute
existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 2.06 shall apply to the Notes in lieu of
Section 306 of the Base Indenture. 
 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 by Company Order, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any
authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be
executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall
execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency
maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be
made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under the Indenture as Physical Notes
authenticated and delivered hereunder. 

  
 18 








 Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 2.07
shall apply to the Notes in lieu of Section 304 of the Base Indenture.

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 the Company or the Company’s
agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled in accordance with its customary procedures, and no Notes shall be authenticated in exchange thereof except
as expressly permitted by any of the provisions of the Indenture. The Trustee shall retain cancelled Notes in accordance with its customary procedures, and, shall deliver a certificate of such cancellation to the Company, at the Company’s
written request in a Company Order. If the Company or any of its Subsidiaries shall acquire any of the Notes, such acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and
until the same are delivered to the Trustee for cancellation. Any Notes surrendered for cancellation shall not be reissued or resold and shall be promptly cancelled by the Trustee in accordance with its customary procedures. 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 2.08 shall apply to the Notes in lieu of
Section 309 of the Base Indenture. 
 Section 2.09 Additional Notes; Repurchases. The Company may, without the consent of the
Holders and notwithstanding Section 2.01, reopen the original issuance under the Indenture and issue additional Notes hereunder with the same terms and the same CUSIP number as the Notes initially issued hereunder (other than differences in the
issue price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided, however, that if any such additional Notes are not fungible with any other Notes then outstanding
for U.S. federal income tax purposes, then such additional Notes will 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 required by Section 102 of the Base Indenture and that the form and terms of such Notes has been established in conformity with the provisions of
the Indenture and that such Notes, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the
Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general application affecting the rights and remedies of creditors and to general
principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith, fair dealing and unconscionability), regardless of whether considered in a proceeding in equity or law. 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, in each case without prior notice to the Holders. Any Notes repurchased by the Company (other than Notes repurchased pursuant to
cash-settled swaps or other derivatives) shall be surrendered to the Trustee for cancellation in accordance with Section 2.08, shall not be reissued or resold by the Company and shall no longer be considered outstanding upon their repurchase.

 ARTICLE III 

SATISFACTION AND DISCHARGE 

Section 3.01 Satisfaction and Discharge. The Company’s obligations under the Notes, and its obligations under the Indenture with
respect to the Notes, shall, upon request of the Company contained in an Officer’s Certificate, cease to be of further effect, and the Trustee, at the expense and written request of the Company, and all outstanding amounts owed to the Trustee
and other obligations of the Company having been paid, shall execute proper instruments acknowledging satisfaction and discharge of such obligations, when (a) (i) all Notes theretofore authenticated and delivered (other than Notes which
have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06) 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, with respect to Notes to be converted, the consideration due upon such
conversion), as applicable, sufficient to pay or convert all of the outstanding Notes and all other sums due and payable under the 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 such obligations have been complied with. Notwithstanding the satisfaction and discharge of such obligations, the
obligations of the Company to the Trustee under Section 607 of the Base Indenture shall survive. Notwithstanding anything to the contrary in the Base Indenture or the Notes, the Company’s obligations under the Notes, and its obligations
under the Indenture with respect to the Notes, may not be satisfied and discharged pursuant to Article Eight of the Base Indenture; provided, however, that nothing herein shall affect the manner by which satisfaction and discharge with
respect to any series of Securities other than the Notes may be affected. 
 ARTICLE IV 

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. Notwithstanding anything to the
contrary in the Indenture or the Notes, this Section 4.01 shall apply to the Notes in lieu of Section 1001 of the Base Indenture. 

Section 4.02 Maintenance of Office or Agency. The Company will maintain an office or agency in the continential United States of
America 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”). The Company will give prompt
written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

  
 20 








 The Company may also from time to time designate as co-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, however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office in the United States of America as a place for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any
such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 

The Company hereby designates the Trustee as the initial Paying Agent, Registrar, Custodian, Bid Solicitation Agent and Conversion Agent, and
the Corporate Trust Office of the Trustee, or any other office or agency in the United States of America so designated by the Trustee, each shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 

Section 4.03 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 4.03, that 

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

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

(iii) 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 in writing of any failure to take such action; provided, however, 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. 

  
 21 








 (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, or 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) or 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) Notwithstanding anything to the contrary in this Section 4.03, the Company may, at any time, for the purpose of obtaining a
satisfaction and discharge of the Company’s obligations under the Notes, and its obligations under the Indenture with respect to the Notes, 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 4.03, 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 (or other Reference Property) 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, or Conversion Settlement Consideration with respect to, any Note and remaining unclaimed for two years after the same has become due and payable shall be paid or delivered, as applicable, 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 subject to applicable law; and the Holder of such Note shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease.

 (e) The Company shall be responsible for making calculations called for under the Notes, including determinations of the Last Reported
Sale Prices of the Common Stock, the Daily VWAPs, the Daily Conversion Values, the Daily Settlement Amounts, accrued interest payable on the Notes, the Conversion Rate and any other amounts due on the Notes. The Company will make all these
calculations in good faith and, absent manifest error, such calculations will be final and binding on Holders. The Company shall provide a schedule of such calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and the
Conversion Agent is entitled to rely conclusively upon the accuracy of such calculations without independent verification. The Trustee shall forward the Company’s calculations to any Holder upon the written request of such Holder. 

Section 4.04 Reports. (a) The Company shall provide to the Trustee within 15 calendar days after the same are required to be filed
with the Commission (after giving effect to any grace period provided by Rule 12b-25 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 such information, documents or reports, or portions thereof, subject to confidential treatment and any correspondence with the Commission). Any such document or report that the Company files with the Commission via the
Commission’s EDGAR 

  
 22 








 
system (or any successor thereto) shall be deemed to be filed with the Trustee for purposes of this Section 4.04(a) at the time such documents are filed via the EDGAR system (or any
successor thereto), it being understood that the Trustee shall not be responsible for determining whether such filings have been made. Upon request by any Holder, the Trustee shall provide such Holder with a copy of any such documents or reports it
has actually received pursuant to this Section 4.04. 
 (b) Delivery of the reports and documents described in subsection
(a) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate). The Trustee is under no duty to examine such reports, information or documents to ensure
compliance with the provision of the Indenture or to ascertain the correctness or otherwise of the information or the statements contained therein. The Trustee shall have no responsibility or duty whatsoever to ascertain or determine whether the
above referenced filings with the Commission on EDGAR (or any successor system) has occurred. In addition, the Company shall comply with Section 314(a) of the Trust Indenture Act. 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 4.04 shall apply to the Notes in lieu of
Section 704 of the Base Indenture. 
 Section 4.05 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 December 31, 2014) an Officer’s Certificate stating whether or not the signers thereof have knowledge of any
Default that occurred during such fiscal year and, if so, specifying each such Default and the nature thereof. 
 In addition, the Company
shall deliver to the Trustee, as soon as possible, and in any event within 30 calendar days after the Company becomes aware of the occurrence of any Event of Default or Default, an Officer’s Certificate setting forth the details of such Event
of Default or Default, its status and the action that the Company is taking or proposing to take in respect thereof. In the absence of any such notice of default or Event of Default from the Company and any description of default or Event of Default
in such Officer’s Certificate, the Trustee shall not be deemed to have notice or be charged with knowledge of any default or Event of Default. 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 4.05 shall apply to the Notes in lieu of
Section 1004 of the Base Indenture. 
 Section 4.06 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 the Indenture.

LISTS OF HOLDERS AND REPORTS BY THE
COMPANY AND THE TRUSTEE

there are any Physical Notes, the Company covenants and agrees that it will furnish or cause to be furnished to the Trustee, semi-annually, not more than 15 calendar days after each June 15 and December 15 in each year, beginning with
December 15, 2014, and at such other times 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

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 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 VI 

DEFAULTS AND REMEDIES 

Section 6.01 Events of Default. In lieu of the Events of Default enumerated in Section 501 of the Base Indenture, an
“Event of Default” is deemed to occur with respect to the Notes if and only if: 
 (a) default in any payment of interest
on any Note when due and payable, and the default continues for a period of 30 calendar days; 
 (b) default in the payment of principal of
any Note when due and payable on the Maturity Date, upon any required repurchase, upon declaration of acceleration or otherwise; 
 (c)

corporate transaction in accordance with Section 12.01(b)(iii), when due;

under Article X; 
 (f) failure by the Company for 60 calendar days after written notice from the Trustee to the Company, or to the

 24 








 (g) default by the Company or any of its Subsidiaries with respect to any mortgage, agreement or
other instrument under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed (other than non-recourse debt of a Subsidiary of the Company) in excess of $20.0 million (or its foreign currency
equivalent) in the aggregate, 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, and such acceleration shall not have been rescinded or annulled or such failure to pay shall not have been cured,
as the case may be, 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 principal amount of the Notes then outstanding; 

(h) (x) the Company or any of its Significant Subsidiaries (A) shall commence a voluntary case or other proceeding seeking
liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property; (B) shall consent to any such relief or to the appointment of or taking possession by any such official in an
involuntary case or other proceeding commenced against it, or (C) shall make a general assignment for the benefit of creditors, or (y) the Company or any of its Significant Subsidiaries shall admit in writing of the inability of the
Company or any of its Significant Subsidiaries to pay its debts generally as they become due; or 
 (i) an involuntary case or other
proceeding shall be commenced against the Company or any of its Significant Subsidiaries seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or
other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such
involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive 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(h) or
Section 6.01(i) with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding
(determined, for the avoidance of doubt, in accordance with Section 8.04), by written notice to the Company (and to the Trustee if given by Holders), may, and the Trustee, at the written request of such Holders, shall, declare 100% of the
principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, notwithstanding anything to the contrary
in the Notes or the Indenture. If an Event of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the Company occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes
shall become and shall automatically be immediately due and payable. 

  
 25 








 The immediately preceding paragraph, however, is subject to the conditions that if, at any time
after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, and if (1) rescission would not
conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under the Indenture with respect to the Notes, other than the nonpayment of the principal of and accrued and unpaid
interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of
a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may 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 the Indenture with respect to the Notes; but no such rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any
right consequent thereon, provided further that all amounts due to the Trustee under Section 607 of the Base Indenture have been paid. Notwithstanding anything to the contrary in the Indenture or the Notes, no such rescission and
annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase Notes when required, (iii) a
failure to pay or deliver, as the case may be, the Conversion Settlement Consideration due upon conversion of the Notes or (iv) any other provision that requires the consent of each affected Holder to amend. 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.02 shall apply to the Notes in lieu of
Section 502 of the Base Indenture. 
 Section 6.03 Additional Interest in Lieu of Reporting Default. Notwithstanding anything to
the contrary in the Indenture or the Notes, 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 4.04(a) or its obligation set
forth in Section 314(a)(1) of the Trust Indenture Act (such obligations, collectively, “Reporting Obligations”) shall, for the first 365 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 (i) 0.25% per annum of the principal amount of the Notes outstanding for each day during the first 180 calendar days after the occurrence of such Event of Default and
(ii) 0.50% per annum of the principal amount of the Notes outstanding from, and including, the 181st calendar day through, and including, the 365th calendar day following the occurrence of such Event of Default, during which such Event of
Default is continuing. Such Additional Interest, if any, shall accrue from, and including, the date on which such an Event of Default first occurs. If the Company duly so elects, such Additional Interest shall be payable in the same manner and on
the same dates as regular interest on the Notes. On the 365th calendar day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with the Reporting Obligations is not cured or waived prior to such
365th calendar day), the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the
Company elects to make such payment but does not pay the Additional Interest when due, the Notes shall be subject to acceleration as provided in Section 6.02. 

  
 26 








 In order to elect to pay Additional Interest as the sole remedy during the first 365 calendar
days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify in writing all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 365-day
period. Upon the failure to timely give such written notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.03
shall not affect the rights of Holders in the event of the occurrence of any Event of Default other than an Event of Default relating to the Company’s failure to comply with the Reporting Obligations. 

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 pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount of principal and interest, if any, then due and payable on the Notes, with interest on any overdue principal
and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 607 of the Base Indenture. 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. 
 All rights of action and of asserting claims under the Indenture with respect to the Notes, 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 compensation and 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 the Indenture
to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders, and it shall not be necessary to make any Holders parties to any such proceedings. 

In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or
abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then, and in every such case, the Company,
the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall
continue as though no such proceeding had been instituted. 

  
 27 








 Section 6.05 Priorities. Any monies collected by the Trustee pursuant to this
Article VI or Article Five of the Base Indenture 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: 

First, to the payment of all amounts due the Trustee and its agents and attorneys under the Indenture; 

Second, to the Holders, for any amounts due and unpaid on the principal (including the Fundamental Change Repurchase Price, if applicable) of,
and accrued and unpaid interest on, and any cash Conversion Settlement Consideration due upon the conversion of, any Note, without preference or priority of any kind, according to such amounts due and payable on all of the Notes; and 

Third, the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs. 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.05 shall apply to the Notes in lieu of
Section 506 of the Base Indenture. 
 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 Conversion Settlement Consideration due upon conversion, no Holder of any Note shall have any
right by virtue of or by availing of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a receiver, trustee, liquidator, custodian
or other similar official, or for any other remedy under the Indenture, unless: 
 (a) such Holder previously shall have given to the
Trustee written notice of an Event of Default and of the continuance thereof, as herein provided; 
 (b) Holders of at least 25% in
aggregate principal amount of the Notes then outstanding shall have made a written request to the Trustee to pursue such remedy hereunder; 

(c) such Holders shall have offered to the Trustee such security or indemnity satisfactory to it against any loss, liability or expense to be
incurred therein or thereby; 
 (d) the Trustee, for 60 calendar days after its receipt of the request and offer of security or indemnity,
shall not complied with such request; and 
 (e) no direction that, in the opinion of the Trustee, is inconsistent with such written request
shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.09, it being understood and intended, and being expressly
covenanted by the taker and Holder of every Note with every other taker and Holder, and the Trustee, that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of the Indenture to affect,
disturb or prejudice the rights of any other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or 

  
 28 








 
forbearances are unduly prejudicial to such Holders), or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under the Indenture, except in
the manner provided in the Indenture and for the equal, ratable and common benefit of all Holders (except as otherwise provided in the Indenture). 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 anything to the contrary in the Indenture or
the Notes, the right of any Holder of any Note 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 Conversion Settlement Consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of any such payment or
delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder. 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.06 shall apply to the Notes in lieu of Sections
507 and 508 of the Base Indenture. 
 Section 6.07 Proceedings by Trustee. In case of an Event of Default, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by the 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 the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal or equitable right vested in the
Trustee by the Indenture or by law. 
 Section 6.08 Remedies Cumulative and Continuing. All powers and remedies given by this
Article VI to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and agreements contained in the Indenture, and no delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any Default or Event of Default
shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article VI
or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 

Section 6.09 Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority of the aggregate
principal amount of the Notes at the time outstanding (determined, for the avoidance of doubt, in accordance with Section 8.04) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that such direction shall not be in conflict with any rule of law or with the Indenture, and the Trustee may take any other
action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it 

  
 29 








 
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, for the avoidance of doubt, 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 6.02, (ii) a failure by
the Company to pay or deliver, as the case may be, the Conversion Settlement Consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision of the Indenture that, under Article IX, 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 under the Indenture; 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 the 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. 
 Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.09 shall apply to the Notes in lieu
of Sections 513 and 512 of the Base Indenture. 
 Section 6.10 Undertaking to Pay Costs. All parties to the 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 the 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, however, that the provisions of this Section 6.10 (to the extent
permitted by law) shall not apply to any suit instituted by the Trustee, or to any suit instituted by any Holder for the enforcement of the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued
and unpaid interest, if any, on any Note on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article XII. 

Section 6.11 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings
relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any
custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, 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 to it for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607 of the Base Indenture. To the extent that the payment of any such
compensation, expenses, disbursements and 

  
 30 








 
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607 of the Base Indenture out of the estate in any such proceeding, 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, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in
liquidation or under any plan of reorganization or arrangement or otherwise. Nothing 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 the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. The Trustee may, on behalf of the Holders, vote for the
election of a trustee in bankruptcy or similar official and be a member of a creditors’ committee or other similar committee. 

Section 6.12 Notice of Defaults. The Trustee shall, within 90 calendar days after the occurrence and continuance of a Default of
which a Responsible Officer has actual knowledge, send to all Holders as the names and addresses of such Holders appear upon the Register, 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, or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon
conversion, the Trustee shall be protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 

ARTICLE VII 
 [RESERVED] 

ARTICLE VIII 

CONCERNING THE HOLDERS 

Section 8.01 Action by Holders. Whenever in the 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 by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing. Whenever the Company solicits the taking of any
action by the Holders of the Notes, the Company 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 15 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 Article Six of the Base Indenture, 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 reasonably satisfactory to the Trustee. 

  
 31 








 Section 8.03 Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating
agent, any Paying Agent, any Conversion Agent and any Registrar may deem the Person in whose name a Note shall be registered upon the 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 Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03) accrued and
unpaid interest on such Note, for conversion of such Note and for all other purposes under the Indenture; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any 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 the 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 the Indenture. 
 Section 8.04 Company-Owned Notes Disregarded. Subject to the last sentence of Section 2.09, in
determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under the Indenture, Notes that are owned by the Company or by an Affiliate of the Company shall be
disregarded and deemed not to be outstanding for the purpose of any such determination; provided, however, 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 or an Affiliate of the Company. 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 Article Six of the Base Indenture, 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. Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 8.04 shall apply to the Notes in
lieu of clause (i) to the definition of “Outstanding” in the Base Indenture. 
 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
the 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, 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


  
 32 








 
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 IX 

SUPPLEMENTAL INDENTURES 

Section 9.01 Supplemental Indentures Without Consent of Holders. The Company, when authorized by the resolutions of the Board of
Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into indentures supplemental to the Indenture, or amend the Notes, without the consent of any Holder for one or more of the following purposes:

 (a) to cure any ambiguity, omission, defect or inconsistency that does not adversely affect any Holder, or to eliminate any conflict with
the terms of the Trust Indenture Act (it being understood that the Trustee shall not be responsible for making any determination as to whether or not such change adversely affects any Holder or eliminates any such conflict); 

(b) to provide for the assumption by a Successor Company of the Company’s obligations under the Indenture and the Notes pursuant to
Article X; 
 (c) to add guarantees with respect to the Notes; 

(d) to secure the Notes; 
 (e)
to add to the Company’s covenants or to Events of Default for the benefit of the Holders or to surrender any right or power conferred upon the Company; 

(f) to make any change that does not adversely affect the rights under the Indenture of any Holder (it being understood that the Trustee shall
not be responsible for making any determination as to whether such adversely affects the rights of any Holder); 
 (g) to increase the
Conversion Rate as provided in the Indenture; 
 (h) to provide for the issuance of additional Notes solely in accordance with the
limitations set forth in the Indenture; 
 (i) to comply with requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act; 
 (j) to provide for the acceptance of appointment by a successor trustee
pursuant to Article Six of the Base Indenture or to facilitate the administration of the trusts by more than one trustee; 
 (k) to
irrevocably elect a Settlement Method or a Specified Dollar Amount; 

  
 33 








 (l) to comply with the Applicable Procedures of the Depositary for the Notes; or 

(m) to conform the provisions of the Indenture or the Notes to the “Description of Notes” in the Prospectus Supplement, related to
the offering of the Notes, as evidenced by an Officer’s Certificate (which Officer’s Certificate shall be delivered to the Trustee). 

Upon the written request of the Company, accompanied by (i) a certified copy of resolutions of the Board of Directors authorizing the
execution of any such supplemental indenture or such amendment to the Notes; (ii) an Officer’s Certificate; and (iii) an Opinion of Counsel stating that the execution of such supplemental indenture or amendment is authorized or
permitted by the Indenture, and an Opinion of Counsel in accordance with Section 102 of the Base Indenture and stating that such amended or supplemental indenture or amendment will be the legal, valid and binding obligation of the Company in
accordance with its terms, the Trustee shall join with the Company in the execution of such supplemental indenture or such amendment, unless such supplemental indenture or amendment affects the Trustee’s own rights, duties or immunities under
the Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental Indenture. 

Any supplemental indenture or amendment authorized by the provisions of this Section 9.01 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 9.02. 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 9.01 shall apply to the Notes in lieu of
Section 901 of the Base Indenture. 
 Section 9.02 Supplemental Indentures with Consent of Holders. With the consent (evidenced
as provided in Article VIII) of the Holders of at least a majority of the aggregate principal amount of Notes then outstanding (determined, for the avoidance of doubt, in accordance with Section 8.04 and including consents obtained in
connection with a repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an
indenture or indentures supplemental hereto or amend the Notes for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or any supplemental indenture or of modifying in any manner
the rights of the Holders; provided, however, that, without the consent of each Holder of an outstanding Note affected, no such supplemental indenture shall: 

(a) reduce the amount of Notes whose Holders must consent to an amendment or waiver; 

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

(c) reduce the principal of or extend the Maturity Date of any Note; 

(d) make any change that adversely affects the conversion rights of any Notes; 

  
 34 








 (e) reduce the Fundamental Change Repurchase Price of any Note or amend or modify in any manner
adverse to the Holders the Company’s obligation to offer to repurchase and repurchase the Notes, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise; 

(f) make any Note payable in money, or at a place of payment, other than that stated in the Note; 

(g) change the ranking of the Notes; 

(h) impair the right of any Holder to receive payment of principal and interest on such Holder’s Notes on or after the due dates therefor
or to institute suit for the enforcement of any payment on or with respect to such Holder’s Note; or 
 (i) make any change in this
Article IX or the Notes that requires each Holder’s consent or in the waiver provisions in Section 6.02 or Section 6.09, if such change adversely affects the rights of the Holders. 

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject
to Section 102 of the Base Indenture, the Trustee shall join with the Company in the execution of such supplemental indenture or amendment unless such supplemental indenture or amendment affects the Trustee’s own rights, duties or
immunities under the Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture or amendment. 

Holders do not need, under this Section 9.02, to approve the particular form of any proposed supplemental indenture or amendment to the
Notes. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture or amendment becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental indenture or
amendment. 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 or amendment. 

Section 9.03 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture or amendment to the Notes pursuant to
the provisions of this Article IX, the Indenture and the Notes 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 the Indenture and
the Notes 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
or amendment shall be and be deemed to be part of the terms and conditions of the Indenture and the Notes for any and all purposes. 

Section 9.04 Evidence of Compliance of Supplemental Indenture to Be Furnished to Trustee. In addition to the documents required by
Section 102 of the Base Indenture, the Trustee shall receive, and shall be fully protected in conclusively relying upon, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such supplemental indenture or


  
 35 








 
amendment is authorized or permitted by the Indenture, and an Opinion of Counsel in accordance with Section 102 of the Base Indenture and stating that such supplemental indenture or
amendment complies with the requirements of this Article IX and is permitted or authorized by the Indenture. Such Opinion of Counsel will also state that such supplemental indenture or amendment is a valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general application affecting the rights and remedies of creditors and to
general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith, fair dealing and unconscionability), regardless of whether considered in a proceeding in equity or law. 

ARTICLE X 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Notwithstanding anything to the contrary in the Indenture or the Notes, this Article X shall apply to the Notes in lieu of Article Eight
of the Base Indenture. 
 Section 10.01 Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of
Section 10.02, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to another Person, unless:

 (a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, all of the obligations of the
Company under the Notes and the Indenture; 
 (b) immediately after giving effect to such transaction, no Default or Event of Default shall
have occurred and be continuing under the Indenture; and 
 (c) the Trustee shall have received an Officer’s Certificate and an Opinion
of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture,
complies with the provisions of this Article X. 
 Section 10.02 Successor Corporation to Be Substituted. In case of any such
consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment or
delivery, as applicable, of the principal of and accrued and unpaid interest on, and the Conversion Settlement Consideration with respect to, all of the Notes, and the due and punctual performance of all of the covenants and conditions of the
Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease, 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 cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall


  
 36 








 
not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in
the Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication,
and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under the Indenture as the Notes
theretofore or thereafter issued in accordance with the terms of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in
the case of a lease), upon compliance with this Article X the Person named as the “Company” in the first paragraph of this Supplemental Indenture (or any successor that shall thereafter have become such in the manner prescribed in
this Article X) 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 the
Indenture with respect to the Notes and under the Notes. 
 In case of any such consolidation, merger, sale, conveyance, transfer or lease,
such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 

ARTICLE XI 

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND
DIRECTORS 
 Section 11.01 Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the
principal of or accrued and unpaid interest on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or in any supplemental
indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of the Company
or of any Successor Company, either directly or through the Company or any Successor Company, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of the Indenture and the issue of the Notes. Notwithstanding anything to the contrary in the Indenture or the
Notes, this Section 11.01 shall apply to the Notes in lieu of Section 115 of the Base Indenture. 
 ARTICLE XII 

CONVERSION OF NOTES 

Section 12.01 Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article XII, 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
below in Section 12.01(b), at any time prior to the Close of Business on the Business Day immediately preceding December 15, 2018, under the circumstances and during the periods set forth in 

  
 37 








 
Section 12.01(b), and (ii) irrespective of the conditions below in Section 12.01(b), on or after December 15, 2018, and at any time prior to the Close of Business on the
second Scheduled Trading Day immediately preceding the Maturity Date into Conversion Settlement Consideration in the manner provided in, and subject to, this Article XII. 

(b) (i) Prior to the Close of Business on the Business Day immediately preceding December 15, 2018, a Holder may surrender
all or any portion of its Notes for conversion during any calendar quarter commencing after the calendar quarter ending on September 30, 2014 (and only during such calendar 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 calendar quarter is greater than 130% of the Conversion Price on each applicable Trading
Day. 
 (ii) Prior to the Close of Business on the Business Day immediately preceding December 15, 2018, a Holder may
surrender all or any portion of its Notes for conversion during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount
of Notes, as determined following a request by a Holder of Notes in accordance with this subsection Section 12.01(b)(ii), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the
Common Stock and the Conversion Rate on each such Trading Day, subject to compliance with the procedures and conditions described below concerning the Bid Solicitation Agent’s obligation to make a Trading Price determination. The Trading Prices
shall be determined by the Bid Solicitation Agent pursuant to this subsection Section 12.01(b)(ii) and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other
than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent (if other than
the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is
acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes) unless a Holder 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 (if other than the Company) to
determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of Notes 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 the Trading Price condition set forth above has been met, the Company shall so notify the
Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the Trading Price condition set forth above has 

  
 38 








 
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 applicable Conversion
Rate, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee). If the Company does not, when required as provided above, instruct the Bid Solicitation Agent (if other than the Company)
to determine the Trading Price per $1,000 principal amount of Notes, or if the Company instructs the Bid Solicitation Agent (if other than the Company) to obtain bids, and the Bid Solicitation Agent fails to make such determination, 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. 

(iii) If, prior to the Close of Business on the Business Day immediately preceding December 15, 2018, the Company elects
to: 
 (A) distribute to all or substantially all holders of its Common Stock any rights, options or warrants entitling them,
for a period of not more than 45 calendar days after the declaration date for such distribution, to subscribe for or purchase shares of its 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 declaration date for such distribution; or 

(B) distribute to all or substantially all holders of its Common Stock the Company’s assets, securities or rights 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 immediately preceding the
declaration date for such distribution, 
 then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if
other than the Trustee) at least 85 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,
even if the Notes are not otherwise convertible at such time. 
 (iv) If a transaction or event that (x) constitutes a
Fundamental Change occurs, (y) constitutes a Make-Whole Fundamental Change occurs or (z) if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of the Company’s
assets, pursuant to which the Common Stock would be converted into cash, securities or other assets not set forth in (x) and (y) above, in each case prior to the Close of Business on the Business Day immediately preceding December 15,
2018, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 13.01, then all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the date
that is 85 

  
 39 








 
Scheduled Trading Days prior to the anticipated effective date of the transaction or event (or, if later, the date on which the Company provides notice of such transaction or event) until the
earlier of (A) 35 Trading Days after the actual effective date of such transaction or event or, if such transaction or event also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date, and (B) the second
Scheduled Trading Day immediately preceding the Maturity Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly as practicable following the date the Company publicly announces
such transaction but in no event less than 85 Scheduled Trading Days prior to the anticipated effective date of such transaction or (ii) if the Company does not have knowledge of such transaction at least 85 Scheduled Trading Days prior to the
anticipated effective date of such transaction, within one Business Day of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction;
provided, however, that, notwithstanding the foregoing, in no event will the Company be required under this Indenture to provide such notice before the earlier of such time as the Company or the Company’s affiliates (x) have
publicly disclosed or acknowledged the circumstances giving rise to such transaction and (y) are required to publicly disclose under applicable law or the rules of any securities exchange on which the Common Stock is then listed or admitted for
trading the circumstances giving rise to such transaction. 
 Section 12.02 Conversion Procedure; Settlement Upon Conversion. 

(a) Settlement Method. Upon the conversion of any Note, the Company shall settle such conversion by paying or delivering, as applicable
and as provided in this Article XII, either (A) solely cash (a “Cash Settlement”); (B) shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in the proviso to
Section 12.02(b) (a “Physical Settlement”); or (C) a combination of cash and shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in the proviso to Section 12.02(b) (a
“Combination Settlement”). The Company shall have the right to elect the Settlement Method applicable to any conversion of a Note; provided, however, that: 

(i) all conversions of Notes whose Conversion Date occurs on or after the 162nd Scheduled Trading Day immediately preceding the
scheduled Maturity Date will be settled using the same Settlement Method, and the Company shall send written notice of such Settlement Method, to the Holders, the Conversion Agent and the Trustee no later than the 165th Scheduled Trading Day
immediately preceding the scheduled Maturity Date; 
 (ii) the Company shall use the same Settlement Method for all
conversions of Notes whose Conversion Dates occur on the same day (and, for the avoidance of doubt, the Company shall not be obligated to use the same Settlement Method with respect to conversions of Notes whose Conversion Dates occur on different
days, except as provided in clause (i) above); 
 (iii) if the Company elects a Settlement Method with respect to the
conversion of any Note whose Conversion Date occurs before December 15, 2018, the Company shall send written notice of such Settlement Method to the Holder of such Note, the Conversion Agent and the Trustee no later no later than the Close of
Business on the Trading Day immediately following such Conversion Date; 

  
 40 








 (iv) if the Company does not timely elect a Settlement Method with respect to the
conversion of a Note, then the Company will be deemed to have elected Combination Settlement with a Specified Dollar Amount per $1,000 principal amount of such Note equal to $1,000; and 

(v) if the Company timely elects Combination Settlement with respect to the conversion of a Note but does not timely notify the
Holder of such Note, the Conversion Agent, and the Trustee of the Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of such Note. 

(b) Conversion Settlement Consideration. The type and amount of consideration (the “Conversion Settlement
Consideration”) due in respect of each $1,000 principal amount of a Note to be converted shall be as follows: 
 (i)
if Physical Settlement applies to such conversion, a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion; 

(ii) if Cash Settlement applies to such conversion, cash in an amount equal to the sum of the Daily Conversion Values for each
of the 80 consecutive VWAP Trading Days in the Observation Period for such conversion; or 
 (iii) if Combination Settlement
applies to such conversion, a settlement amount equal to the sum of the Daily Settlement Amounts for each of the 80 consecutive VWAP Trading Days in the Observation Period for such conversion; 

provided, however, that if the total number of shares of Common Stock to be delivered with respect to the conversion of any Note is not a whole
number, then the total number of shares so deliverable shall be rounded down to the nearest whole number and the Company shall deliver cash in lieu of the related fractional share in an amount equal to the product of such fraction and the Daily VWAP
on the Conversion Date for such conversion (in the case of Physical Settlement) or the Daily VWAP on the last VWAP Trading Day of the Observation Period for such conversion (in the case of Combination Settlement). 

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) in writing 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. 

  
 41 








 (c) Procedures to Convert a Note. Subject to Section 12.02(f), before any Holder of a
Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the Applicable Procedures of the Depositary in effect at that time (and any instruction to convert transmitted to the
Depositary shall be irrevocable) and, if required, pay funds equal to interest payable on the next Interest Payment Date as set forth in Section 12.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver
a notice (which shall be irrevocable) to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein
the principal amount of Notes to be converted (which must be an integral multiple of $1,000) 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, and
(3) if required, pay funds equal to interest payable on the next Interest Payment Date as set forth in Section 12.02(h). The Trustee (and, if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this
Article XII no later than the Business Day following the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change
Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 13.02. 

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

(d) Delivery of the Conversion Settlement Consideration. Subject to Section 12.03(b), Section 12.04(c), Section 12.04(e)
and Section 12.06, the Company shall pay or deliver, as the case may be, the Conversion Settlement Consideration due in respect of the Conversion Obligation of a Note to be converted on the third Business Day immediately following the relevant
Conversion Date (if the Company elects Physical Settlement) or on the third Business Day immediately following the last VWAP Trading Day of the relevant Observation Period (in the case of any other Settlement Method); provided that with
respect to any Conversion Date occurring on or after December 15, 2018, settlement will occur on the Maturity Date. 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. For the avoidance of doubt, neither the Conversion Agent nor the Trustee shall have any responsibility for the issuance of shares of Common Stock by the Company. 

  
 42 








 (e) Partial Conversions. 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, 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. 
 (f) Taxes. If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or
transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The
Company 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 Company receives a sum sufficient to pay any tax that is due by such Holder in accordance with
the immediately preceding sentence. 
 (g) Conversion of Global Notes. 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) Treatment and Payment of Interest upon Conversion. Upon conversion of a
Note, the Holder of such Note shall not receive any separate cash payment for accrued and unpaid interest, if any, on such Note, except as set forth below. The Company’s settlement of the related Conversion Obligation shall be deemed to satisfy
in full its obligation to pay the principal amount of such Note and accrued and unpaid interest, if any, on such Note to, but not including, the relevant Conversion Date. As a result, except as set forth below, accrued and unpaid interest, if any,
to, but, not including, such 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. However, Notes surrendered for conversion during the period after the Close of Business on any Regular
Record Date to the Open of Business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable, on such Interest Payment Date, on the Notes so converted; provided that no such
payment shall be required (1) for conversions 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 exist at the time of conversion with respect to such Note.
Therefore, for the 

  
 43 








 
avoidance of doubt, all Holders of record as of the Close of Business on the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the
Maturity Date regardless of whether their Notes have been converted following such Regular Record Date. 
 (i) Record Holders of Shares
Due upon Conversion. If any Note is converted, the Person in whose name the certificate for any shares of Common Stock deliverable upon such conversion is to be registered shall be treated as a stockholder of record of such shares as of the
Close of Business on the relevant Conversion Date (in the case of Physical Settlement) or as of the Close of Business on the last VWAP Trading Day of the relevant Observation Period (in the case of 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. 
 Section 12.03 Increased
Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes. (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert any
Note “in connection with” (as defined below) such Make-Whole Fundamental Change, the Company shall, under the circumstances set forth below, increase the Conversion Rate applicable to such Note by a number of additional shares of Common
Stock (the “Additional Shares”), as set forth below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if (A) for Conversion Dates prior to
December 15, 2018, the applicable Conversion Date occurs during the period when the Notes are convertible on account of such Make-Whole Fundamental Change in accordance with the provisions described in Section 12.01(b)(iv) and (B) for
Conversion Dates on or after December 15, 2018, if the applicable Conversion Date occurs during the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to
the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following
the Effective Date of such Make-Whole Fundamental Change). 
 (b) Upon surrender of Notes for conversion in connection with a Make-Whole
Fundamental Change pursuant to this Section 12.03, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 12.02 based on the
Conversion Rate as increased to reflect the Additional Shares pursuant to this Section 12.03; 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, then, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation
shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the applicable Conversion Rate (including any adjustment for Additional
Shares), multiplied by such Stock Price. In such event, the Conversion Obligation will be determined and shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes
(with a copy to the Trustee) of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

  
 44 








 (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased
shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed
to be paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition
of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the
Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. 
 (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 12.04. 

(e) The following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000
principal amount of Notes pursuant to this Section 12.03 for each Stock Price and Effective Date set forth below:

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

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in
the table above, the number of Additional Shares by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the
earlier and later Effective Dates, as applicable, based on a 365- or 366-day year, as applicable; 
 (ii) if the Stock Price
is greater than $50.00 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 

  
 45 








 (iii) if the Stock Price is less than $10.01 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 will the Conversion Rate be increased pursuant to this Section 12.03 to exceed 99.9000 shares
of Common Stock per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 12.05. 

(f) Nothing in this Section 12.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 12.05 in respect of a
Make-Whole Fundamental Change. For these purposes, if the Conversion Rate is to be adjusted in connection with a Make-Whole Fundamental Change pursuant to both Section 12.05 and this Section 12.03 with respect to any Note, then the
adjustment pursuant to Section 12.05 shall be effected before any adjustment pursuant to this Section 12.03. 
 Section 12.04
Adjustments to the 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 each Holder
participates (other than in the case of a stock split or stock combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this
Section 12.04, without having to convert its Notes, as if such Holder 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 all or substantially all shares of Common Stock,
or if the Company effects a stock split or stock combination, the Conversion Rate will be adjusted based on the following formula: 
  

									
		 	CR1 = CR0 × 	 	OS1	 		 	
	 	 	OS0	 		 	

 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 stock split or stock
combination, as applicable;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or Effective Date, as applicable;
			
	OS0	  	=	  	the number of shares of the Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or Effective Date, as applicable; and
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock combination, as applicable.


  
 46 








 Any adjustment made under this Section 12.04(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 stock split or stock combination, as applicable. If any dividend, distribution, stock split or stock
combination of the type described in this Section 12.04(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 or effect such stock split or stock combination to the Conversion Rate that would then be in effect if such dividend or distribution or stock split or stock combination had not been declared or announced. 

(b) If the Company distributes to all or substantially all holders of Common Stock any rights, options or warrants (other than rights issued
pursuant to a stockholder rights plan) entitling them, for a period of not more than 45 calendar days after the declaration date of such distribution, 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 declaration date of such distribution, the Conversion Rate will be increased
based on the following formula: 
  

							
		 	CR1 = CR0 ×	 	OS0 + X	  	
	 	 	OS0 + Y	  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of the Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of the 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 declaration date of the distribution of such rights, options or warrants.

 Any increase made under this Section 12.04(b), and for the purpose of Section 12.01(b)(iii)(A), will
be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. To the extent that shares of Common Stock are not


  
 47 








 
delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the
issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased to
the Conversion Rate that would then be in effect if such Ex-Dividend Date for such distribution had not occurred. 
 For the purpose of this
Section 12.04(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price per share price that is less than such average of the Last Reported Sale Prices for
the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the declaration date of such distribution, and in determining the aggregate price payable to exercise such rights, options or warrants, 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 the Company’s Capital Stock or other securities, to all or substantially all holders of Common Stock, excluding: 

(i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 12.04(a) or
Section 12.04(b) 
 (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected
pursuant to Section 12.04(d); and 
 (iii) Spin-Offs as to which the provisions set forth below in this
Section 12.04(c) shall apply, 
 then the Conversion Rate will be increased based on the following formula: 

 

							
		 	CR1 = CR0 ×	 	      SP0      	  	
	 	 	SP0 – FMV	  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	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 shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed with respect to each outstanding share of the
Common Stock as of the open of business on the Ex-Dividend Date for such distribution.


  
 48 








 Any increase made under the portion of this Section 12.04(c) above will 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, or if any rights, options or warrants are not exercised before their expiration date, the Conversion Rate shall be
readjusted to be the Conversion Rate that would then be in effect if such distribution had not been declared or on the basis of the rights, options or warrants actually exercised before their expiration date, as applicable. Notwithstanding the
foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), then, in lieu of the foregoing increase, each Holder shall receive, in respect
of each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of such Capital Stock, evidences of indebtedness, other assets, property, rights, options or warrants that such
Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date for such distribution. 

With respect to an adjustment pursuant to this Section 12.04(c) where there has been a payment of a dividend or other distribution on 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, and such Capital Stock or equity interest is, or, when issued, will be, listed or admitted for trading
on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula: 
  

							
		 	CR1 = CR0 ×	 	  FMV0 + MP0  	  	
	 	 	MP0	  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date of such Spin-Off;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last
Reported Sale Price as if references in such definition to the Common Stock were instead to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of such Spin-Off
(the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.


  
 49 








 Any increase to the Conversion Rate under the preceding paragraph will be calculated as of the
Close of Business on the last Trading Day of the Valuation Period but will be given effect as of immediately after the Open of Business on the Ex-Dividend Date of the Spin-Off. Notwithstanding the foregoing, (i) if the conversion settlement
date for a Note whose conversion is to be settled pursuant to Cash Settlement or Combination Settlement occurs on or before the last Trading Day in the Valuation Period and any VWAP Trading Day in the Observation Period for such Note occurs on any
Trading Day within the Valuation Period, then, solely for purposes of determining the Conversion Settlement Consideration due upon such conversion, the Valuation Period shall be deemed to be the period from, and including, the Ex-Dividend Date of
the Spin-Off to, and including, the last VWAP Trading Day in such Observation Period; and (ii) if the conversion settlement day for a Note whose conversion is to be settled pursuant to Physical Settlement occurs on or before the last Trading
Day in the Valuation Period and the Conversion Date for such Note occurs on any Trading Day within the Valuation Period, then, solely for purposes of determining the Conversion Settlement Consideration due upon such conversion, the Valuation Period
shall be deemed to be the period from, and including, the Ex-Dividend Date of the Spin-Off to, and including, such Conversion Date. Because the Company will make the adjustment to the Conversion Rate with retroactive effect, the Company will delay
the settlement of any conversion of Notes where the Conversion Date (in the case of Physical Settlement) or any VWAP Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the
Valuation Period until the third Business Day after the last day of the Valuation Period. If any distribution of the type described in this Section 12.04(c) is declared but not so made, the Conversion Rate shall be immediately readjusted,
effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such distribution had not been declared. 

(d) If any cash dividend or distribution is made to all or substantially all holders of Common Stock, the Conversion Rate will be adjusted
based on the following formula: 
  

							
		 	CR1 = CR0 ×	 	    SP0    	  	
	 	 	SP0 – C	  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	 =
	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company dividends or distributes to holders of the Common Stock.


  
 50 








 Any increase to the Conversion Rate made pursuant to this Section 12.04(d) shall become
effective immediately after the Open of Business on the Ex-Dividend Date for the dividend or distribution triggering such adjustment. If such dividend or distribution is not so paid, the Conversion Rate shall be readjusted, 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), then, in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Notes, at
the same time and upon the same terms as holders of shares of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date for
such cash dividend or distribution. 
 (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange
offer for Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price of Common Stock on the Trading Day next succeeding the last date (such
last date, the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate will be increased based on the following formula: 

 

							
		 	
CR1 = CR0 ×

 
	 	    AC + (SP1 × OS1)    	  	
	 	 	OS0 × SP1	  	

 where, 
  

					
	CR0	  	=	 	the Conversion Rate in effect immediately prior to the Close of Business on the Expiration Date;
			
	CR1	  	=	 	the Conversion Rate in effect immediately after the Close of Business on the Expiration Date;
			
	AC	  	=	 	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares purchased or exchanged in such tender or exchange offer;
			
	OS0	  	=	 	the number of shares of the Common Stock outstanding immediately prior to the time (the “Expiration Time”) such tender or exchange offer expires (prior to giving effect to the purchase or exchange of all shares
accepted for purchase or exchange in such tender or exchange offer);
			
	OS1	  	=	 	the number of shares of the Common Stock outstanding immediately after the Expiration Time (after giving effect to the purchase or exchange of all shares accepted for purchase or exchange in such tender or exchange offer);
and
			
	SP1	  	=	 	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period (the “Averaging Period”) commencing on, and including, the Trading Day next succeeding the Expiration
Date.


  
 51 








 The adjustment to the Conversion Rate under this Section 12.04(e) will be calculated as of
the Close of Business on the last Trading Day of the Averaging Period but will be given effect as of immediately after the Close of Business on the Expiration Date. Notwithstanding the foregoing, (i) if the conversion settlement date for a Note
whose conversion is to be settled pursuant to Cash Settlement or Combination Settlement occurs on or before the last Trading Day in the Averaging Period and any VWAP Trading Day in the Observation Period for such Note occurs on any Trading Day
within the Averaging Period, then, solely for purposes of determining the Conversion Settlement Consideration due upon such conversion, the Averaging Period shall be deemed to be the period from, and including, the Trading Day next succeeding the
Expiration Date to, and including, the last VWAP Trading Day in such Observation Period; and (ii) if the conversion settlement day for a Note whose conversion is to be settled pursuant to Physical Settlement occurs on or before the last Trading
Day in the Averaging Period and the Conversion Date for such Note occurs on any Trading Day within the Averaging Period, then, solely for purposes of determining the Conversion Settlement Consideration due upon such conversion, the Averaging Period
shall be deemed to be the period from, and including, the Trading Day next succeeding the Expiration Date to, and including, such Conversion Date (or, if such Conversion Date is not a Trading Day, the immediately preceding Trading Day). Because the
Company will make the adjustment to the Conversion Rate with retroactive effect, the Company will delay the settlement of any conversion of Notes where the Conversion Date (in the case of Physical Settlement) or any VWAP Trading Day of the
applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the Averaging Period until the third Business Day after the last day of the Averaging Period. 

(f) Subject to the applicable listing standards of The NASDAQ Global Select Market, the Company may (but is not required to) 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. Subject to the applicable listing standards of The NASDAQ Global Select
Market, the Company also may (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or
rights to acquire shares) or similar event. 
 (g) Notwithstanding anything to the contrary in this Section 12.04 in the case of any
conversion of a Note to which Combination Settlement applies, on any VWAP 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 Record Date for any issuance, dividend or distribution, the Effective Date for any stock split or combination or the
Expiration Date for any tender or exchange offer by the Company that, in each case, would require an adjustment to the Conversion Rate under clauses (a) through (e), inclusive, of this Section 12.04 occurs prior to the Company’s
delivery of such shares of the Common Stock to the converting Holder; 
 (ii) the applicable Conversion Rate for such Trading
Day will not reflect such adjustment; and 

  
 52 








 (iii) the shares that the Company will deliver to the converting Holder with
respect of such Trading Day are not entitled to participate in the relevant event (because the converting Holder is not treated as the record Holder of such shares on the related Record Date, Effective Date, Expiration Date or otherwise), 

then the Company will 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, in the Company’s good faith, reasonable judgment, appropriately reflects the relevant distribution, transaction or event. 

(h) Notwithstanding anything to the contrary in the Indenture or the Notes, in respect of any Physical Settlement, if any adjustment to the
Conversion Rate set forth in clauses (a) through (e), inclusive, of this Section 12.04 becomes effective on any Ex-Dividend Date and a Holder that has converted its Notes would: 

(i) receive shares of the Common Stock based on the Conversion Rate as so adjusted; and 

(ii) be a record holder of such shares of the Common Stock on the Record Date for the dividend, distribution or other event
giving rise to the adjustment, 
 then, in lieu of receiving shares of Common Stock at such adjusted Conversion Rate, such Holder shall receive a number of
shares of the Common Stock based on the unadjusted Conversion Rate and will participate in the related dividend, distribution or other event giving rise to the adjustment. 

(i) Notwithstanding anything to the contrary in the Indenture or the Notes to the contrary, if the application of the adjustments set forth in
clauses (a) through (e), inclusive, of this Section 12.04 would result in a decrease in the Conversion Rate, then no adjustment to the Conversion Rate shall be made (other than as a result of a stock combination pursuant to
Section 12.04(a) or the reversal of an increase to the Conversion Rate where the relevant event did not occur, as expressly specified in this Supplemental Indenture). 

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

(k) Notwithstanding anything to the contrary in this Article XII, 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; 

  
 53 








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

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

(iv) upon the repurchase of any shares of 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 under Section 12.04(e); 
 (v) solely
for a change in the par value of the Common Stock; or 
 (vi) for accrued and unpaid interest, if any. 

All calculations and other determinations under this Article XII shall be made by the Company and shall be made to the nearest one-ten
thousandth (1/10,000) of a share. 
 The Company shall not be required to make an adjustment pursuant to clauses (a) through
(e) of this Section 12.04 unless such adjustment would result in a change of at least 1% of the then effective Conversion Rate. However, the Company shall carry forward any adjustment that the Company would otherwise have to make and take
that adjustment into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with respect to the Notes (i) annually on June 15 of each year, (ii) in connection with any
subsequent adjustment to the Conversion Rate that, together with all carried-forward adjustments, would constitute a change of at least 1% in the then-effective Conversion Rate and (iii) (x) on the Conversion Date for any Notes (in the
case of Physical Settlement) and (y) on each VWAP Trading Day of any Observation Period (in the case of Cash Settlement or Combination Settlement). 

(l) 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 mail such notice of such
adjustment of the Conversion Rate to each Holder at its last address appearing on the Register of the Indenture. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

  
 54 








 (m) For purposes of this Section 12.04, the number of shares of Common Stock at any time
outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include
shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 Section 12.05
Adjustments of Prices. Whenever any provision of the 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 such Last
Reported Sale Prices, Daily VWAPs, Daily Conversion Values or Daily Settlement Amounts are to be calculated. 
 Section 12.06 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 a change only in par value, from par value
to no par value or from no par value to par value, or changes resulting from a subdivision or combination of the Common Stock), 

(ii) any consolidation or merger involving the Company, 

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

in each case, as a result of which the Common Stock would be converted into, or exchanged for, or represent solely the right to receive, stock, other
securities, other property or assets (including cash or any combination thereof) (such stock, other securities, other property or assets, the “Reference Property,” and the amount and kind of Reference Property that a holder of one
share of Common Stock would be entitled to receive on account of such transaction, a “Reference Property Unit”) (and any such recapitalization, reclassification, change, consolidation, merger, sale, lease, transfer or exchange, a
“Share Exchange Event”), then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 9.01(f) providing that, , at and after the
effective time of such Share Exchange Event, the right to convert a Note into cash and/or shares of Common Stock shall be changed into the right to convert such Note into cash and/or Reference Property Units; provided, however, that at and after the
effective time of the Share 

  
 55 








 
Exchange Event (A) the Company 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 12.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 12.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been
required to deliver upon conversion of the Notes in accordance with Section 12.02 shall instead be deliverable in Reference Property Units and (III) the Daily VWAP shall be calculated based on the value of a Reference Property Unit. For these
purposes, the Daily VWAP or Last Reported Sale Price of any Reference Property Unit or portion thereof that does not consist of a class of securities will be the fair value of such Reference Property Unit or portion thereof, as applicable,
determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof). 
 If the Share
Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then the composition of the Reference
Property Unit will be deemed to be (i) the weighted average, per share of Common Stock, of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (ii) if no holders of
Common Stock affirmatively make such an election, the types and amounts of consideration actually received, per share of Common Stock, by the holders of Common Stock. If the holders of Common Stock receive only cash in such Share Exchange Event,
then for all conversions of Notes that occur after the effective date of such Share Exchange Event, (i) the consideration due upon conversion of each $1,000 principal amount of Notes shall, for the avoidance of doubt, be solely cash in an
amount equal to the Conversion Rate in effect on the applicable Conversion Date (as, for the avoidance of doubt, may be increased pursuant to Section 12.03), multiplied by the price paid per share of Common Stock in such Share Exchange Event
and (ii) the Company shall satisfy its Conversion Obligations by paying cash to converting Holders on the third Business Day immediately following the applicable Conversion Date. The Company shall notify Holders, the Trustee and the Conversion
Agent (if other than the Trustee) of the composition of the Reference Property Unit as soon as practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that
shall be as nearly equivalent as is possible to the adjustments provided for in this Article XII. If, in the case of any Share Exchange Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or
any combination thereof) of a Person other than the Company or the successor or purchasing corporation, as the case may be, in such Share Exchange Event, then such supplemental indenture shall also be executed by such other Person and shall contain
such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article
XIII. 
 (b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 12.06, the
Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind and amount of Reference Property constituting the Reference Property after the relevant Share Exchange Event, any adjustment to
be made with respect thereto and that all conditions precedent have been complied 

  
 56 








 
with, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be sent to each Holder, at its address appearing on
the Register provided for in the Indenture, 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 Share Exchange Event unless its terms are consistent with this Section 12.06. None of the
foregoing provisions shall affect the right of a Holder to convert its Notes into cash, shares of Common Stock (or other Reference Property) or a combination of cash and shares of Common Stock (or other Reference Property), as applicable, as set
forth in Section 12.01 and Section 12.02 prior to the effective date of such Share Exchange Event. 
 (d) The above provisions of
this Section shall similarly apply to successive Share Exchange Events. 
 Section 12.07 Certain Covenants. 

(a) The Company covenants that any shares of Common Stock issued upon conversion of Notes will be duly authorized, validly issued, fully paid
and non-assessable and free from all taxes (other than taxes payable by a Holder pursuant to Section 12.02(f) and taxes payable by the Company pursuant to Section 15.02), liens and charges with respect to the issue thereof. 

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

(c) 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 converted (assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder, that Physical
Settlement is applicable and that the maximum increase to the Conversion Rate pursuant to Section 12.03 applies). 
 Section 12.08
Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may
require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that
may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. 

  
 57 








 
Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities
or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither
the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 12.06 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 12.06 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 601 of the Base Indenture, 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. The Conversion Agent (if other than the Company or an Affiliate of the Company) shall have the same protection under this
Section 12.08 as the Trustee. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 12.01(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 notice thereof 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 as soon as reasonably practicable after the occurrence of any such event or at such other times as shall be provided for in
Section 12.01(b), or in the case of Section 12.01(b)(i), after the Company has actual knowledge thereof. 
 Section 12.09
Stockholder Rights Plans. If the Company has a stockholder rights plan in effect at the time any Conversion Settlement Consideration is payable or deliverable, as applicable, upon conversion of any Notes, then each share of Common Stock, if
any, so deliverable shall be accompanied with such number of rights as would be accompanied by such shares pursuant to such rights plan if such shares were issued in the circumstances set forth in such rights plan as would entitle such shares to be
so accompanied by such rights. However, if prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, then in such case, and only in such
case, 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 shares of its Capital Stock, evidences of its indebtedness, other assets or property of the
Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities as provided in Section 12.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

ARTICLE XIII 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 13.01 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 

  
 58 








 
multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 Business Days or more than 35 Business Days following
the date of the Fundamental Change Company Notice (or, if the Company fails to specify a Fundamental Change Repurchase Date, the 35th Business Day 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, on such Interest Payment Date, 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 XIII. 

(b) Repurchases of Notes under this Section 13.01 shall be made, at the option of the Holder thereof, upon: 

(i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase
Notice”) substantially in the form set forth in Attachment 2 to the Form of Note 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 on or before the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental
Change Repurchase Notice but on or before the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date (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; 
 provided, however, that if such Notes are represented by Global Notes, the Holder thereof must comply with the Applicable
Procedures. 
 (c) 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


  
 59 








 (iii) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and the 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 13.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change
Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 13.02. 
 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. 

(d) On or before the 10th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of Notes, the
Conversion Agent, 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. Each Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change; 

(ii) the effective date of the Fundamental Change; 

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

(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) the Conversion Rate and, if applicable, any adjustments to the Conversion Rate resulting from such Fundamental Change;

 (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 the Indenture; and 

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

  
 60 








 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 13.01. 

At the Company’s written 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. 

(e) 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. 

(f) Notwithstanding the foregoing, the Company will not be required to make an offer to repurchase Notes pursuant to this Article XIII if
a Person other than the Company makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer to repurchase Notes pursuant to this Article XIII made by the Company and such Person purchases all Notes
properly tendered and not validly withdrawn under its offer in the same manner as the Company would have been required pursuant to this Article XIII. 

Section 13.02 Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in
whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with this Section 13.02 at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change
Repurchase Date, specifying: 
 (i) the principal amount of the Notes with respect to which such notice of withdrawal is
being submitted, which must be in principal amounts of $1,000 or an integral multiple thereof; 
 (ii) if Physical Notes have
been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted, and 

(iii) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice,
which must be in principal amounts of $1,000 or an integral multiple thereof; 
 provided, however, that if the Notes are Global Notes, the
notice must comply with appropriate procedures of the Depositary.

 Section 13.03 Deposit of Fundamental Change Repurchase Price. (a) The Company will
deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.03(b)) 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 or Notes by the Trustee (or other Paying
Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of
(i) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions in Section 13.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or
other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 13.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the 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 Notes that have been properly surrendered for repurchase and have not been validly withdrawn in accordance with the provisions of the Indenture, (i) such Notes will cease to be outstanding,
(ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent), except as otherwise provided herein and (iii) all other
rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price or, to the extent provided herein, interest due on such Note on the next Interest Payment Date). 

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 13.01, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered. 

Section 13.04 Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the Company
will, if required: 
 (a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act; 

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

(c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes, in each
case, so as to permit the rights and obligations under this Article XIII to be exercised in the time and in the manner specified in this Article XIII. 

  
 62 








 To the extent that the provisions of any securities laws or regulations conflict with the
provisions of the Indenture relating to the Company’s obligations to purchase the Notes upon a Fundamental Change, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its
obligations under Article XIII by virtue of such conflict.

 [FORM OF REVERSE OF NOTE] 

Renewable Energy Group, Inc. 

2.75% Convertible Senior Note due 2019 

This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.75% Convertible Senior Notes due 2019 (the
“Notes”), issued or to be issued under and pursuant to an Indenture (the “Base Indenture”), dated as of June 3, 2014, between the Company and Wilmington Trust, National Association (the
“Trustee”), and the First Supplemental Indenture (the “Supplemental Indenture”), dated as of June 3, 2014, between the Company and the Trustee. The Base Indenture, as amended, modified and supplemented by the
Supplemental Indenture, is herein referred to as the “Indenture.” Reference is hereby made to the Indenture and all indentures supplemental thereto for a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note
and not defined in this Note shall have the respective meanings set forth in the Indenture. In the event of any inconsistency between this Note and the Indenture, the provisions of the Indenture shall govern. 

In the event of certain Events of Default (other than an Event of Default specified in Section 6.01(h) or Section 6.01(i) of the
Supplemental Indenture with respect to the Company) shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee (by notice to the Company) or by Holders of at least 25% in aggregate
principal amount of the Notes then outstanding (by notice to the Company and the Trustee), 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 provided in the Indenture, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as set forth therein. The Indenture also provides 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 

  
 A-5 








 
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 Conversion Settlement Consideration
due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money set forth in the Indenture. 

The Notes are issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples thereof.
At the office or agency of the Company provided in the manner set forth 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, subject to conditions
specified in the Indenture, prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of
Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 

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