in writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. 
 (c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date by virtue of its having been such Holder but shall accrue interest per annum at the rate borne by
the Notes plus one percent, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date to, but excluding, the date on which such Defaulted Amounts shall have been paid by the Company, at its
election in each case, as provided in clause (i) or (ii) below:

had not ceased to be such Officer of the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution
of this Indenture any such Person was not such an Officer.

Depositary. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note
Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being

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

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the

the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 
 All
Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing. 
 No service charge shall be charged to the Holder by the Company, the Trustee or the Note Registrar for any exchange or registration of transfer of Notes, but the Company or the Trustee may require a
Holder to pay a sum sufficient to cover any tax or other similar governmental charge required by law or permitted pursuant to Section 12.02(d) or Section 12.02(e). 
 None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any
Note is surrendered for conversion, such portion thereof surrendered for 

  
 15 









 
conversion, (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 13 or (iii) any Notes selected for redemption (in whole or in part)
in accordance with Article 14. 
 All Notes issued upon any registration of transfer or exchange of Notes in accordance with
this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. 

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all Notes shall be
represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not
involve the issuance of a Physical Note, shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture and the procedures of the Depositary therefor. 

Notwithstanding any other provisions of this Indenture, (other than the provisions set forth in the second succeeding paragraph in this
Section 2.05(b)), 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 Physical Note 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 initially appoints The Depository Trust Company
to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for
Cede & Co. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to
continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within
90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of the Notes requests that its Notes be issued as Physical Notes, the Company will execute, and the Trustee, upon receipt of an
Officers’ Certificate and a Company Order for the authentication and delivery of Notes, will authenticate and deliver Physical Notes to each such beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount
equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note 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


  
 16 









 
Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical
Notes to the Persons in whose names such Physical Notes are so registered. 
 At such time as all interests in a Global Note
have been converted, canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any
time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred
for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be,
and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 
 Neither 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 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. 
 Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written
request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of
and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be
required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee
and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such
authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in
relation thereto and any other expenses connected therewith. 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 12 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 

  
 17 









 
or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof. 
 Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of
the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but
shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that
the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute
existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 
 Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of
the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations
as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in
substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon
any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and
deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all
respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder. 
 Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, repurchase, redemption, registration of transfer or exchange or
conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly
by it, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes delivered to it in accordance with its customary procedures and,
after such disposition, upon request of the Company, shall deliver a certificate of such disposition to the Company. If the Company 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. 

  
 18 









 Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the
Trustee in writing of any change in the “CUSIP” numbers. 
 Section 2.10. Additional Notes; Repurchases. The
Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder in an unlimited aggregate principal amount;
provided that if the additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, the additional Notes will have a separate CUSIP number. Prior to the issuance of any additional Notes, the
Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 15.09, as the
Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether
by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other
than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08. 
 ARTICLE 3 
 SATISFACTION AND DISCHARGE

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


  
 19 









 
complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive. 

ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

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

Section 4.02. Maintenance of Office or Agency. The Company shall maintain an office or agency where the Notes may be surrendered
for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the
Notes and this Indenture may be served. The Company shall 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 or the office or agency of the Trustee. The Company may change the
Paying Agent or the Note Registrar at any time without prior notice to the Holders. The Company may act as Paying Agent or Note Registrar in its discretion. 
 The Company may also from time to time designate as co-Note Registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time
to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency for such purposes. The Company shall 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, subject to the provisions of Section 4.04. 
 The Company hereby initially designates the Trustee
as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office and the office or agency of the Trustee, each shall be considered as one such office or agency of the Company for each of the aforesaid purposes.

 Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or
fill a vacancy in the office of Trustee, shall appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder. 
 Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company shall cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 

  
 20 









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

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

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

  
 21 









 
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; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, The City of New York, notice that such money and shares of Common Stock remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money and shares of Common Stock then remaining will be repaid or delivered to the Company. 
 Section 4.05. Existence. Subject to Article 10, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 

Section 4.06. Reports. (a) The Company shall file with the Trustee within 15 days after the same are required to be filed
with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the Exchange
Act). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section 4.06(a) at the time such documents are filed via the
EDGAR system. 
 (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 Officers’ Certificate). 
 Section
4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may
affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder,
delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 4.08. Compliance Certificate; Statements as to Defaults. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal
year ending on December 31, 2011) an Officers’ Certificate stating whether or not the signers thereof have knowledge of any failure by the Company to comply with all conditions and covenants then required to be performed under this
Indenture and, if so, specifying each such failure and the nature thereof. 
 In addition, the Company shall deliver to the
Trustee, as soon as possible, and in any event within 30 days after the Company becomes aware of the occurrence of any Event of 

  
 22 









 
Default or Default, an Officers’ Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company proposes to take with respect thereto.

 Section 4.09. Further Instruments and Acts. Upon request of the Trustee, the Company shall execute and deliver such
further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 
 ARTICLE 5 
 LISTS OF HOLDERS
AND REPORTS BY THE COMPANY AND THE TRUSTEE 
 Section 5.01. Lists of Holders. The Company covenants and agrees that it shall furnish or cause to be furnished to the Trustee, semi-annually, not more than 15 days after each January 15 and
July 15 in each year beginning with July 15, 2011, and at such other times as the Trustee may request in writing, within 30 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 days (or such other date as the

whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable without such indebtedness having been discharged or the acceleration of payment of such
indebtedness having been cured, rescinded, waived or annulled within 30 days after written notice to the Company by the Trustee or the Holders of at least 25% of the principal amount of the outstanding Notes or (ii) constituting a failure to

 24 









 
any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive days. 

Section 6.02. Acceleration; Rescission and Annulment. In case one or more Events of Default shall have occurred and be continuing
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of
the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by notice in writing to the Company
(and to the Trustee if given by Holders), may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable, and upon any such declaration the same shall become and shall automatically be immediately due
and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company or any of its Significant Subsidiaries
occurs and is continuing, the principal of, and accrued and unpaid interest on, all Notes shall be automatically and immediately due and payable. 
 This Section 6.02, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the
payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of
any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal
at the rate borne by the Notes plus one percent at such time) and amounts due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and
(2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or
waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, including any Holders whose consents
were obtained in connection with repurchases, tender offers or exchanges of the Notes, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration
and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall
affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of
Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the
consideration due upon conversion of the Notes. 

  
 25 









 Section 6.03. Additional Interest. Notwithstanding anything in this Indenture or in
the Notes to the contrary, to the extent the Company elects, the sole remedy for Event of Default relating to the Company’s failure to file with the Trustee as set forth in Section 314(a)(1) of the Trust Indenture Act 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 or as set forth in Section 4.06(a) shall after the occurrence of such an Event of Default consist exclusively of the right
to receive Additional Interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each day during the 90-day period on which such Event of Default is continuing beginning on, and including, the
date on which such an Event of Default first occurs. If the Company 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 91st day after such Event of Default (if the
Event of Default relating to the Company’s failure to file is not cured or waived prior to such 91st 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. 
 In order to elect to pay Additional Interest as the sole remedy during the first 90 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 90-day period. Upon
the Company’s failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 
 Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand
of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by
the Notes plus one percent at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against
the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the
Notes under title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession
of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company
or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and 

  
 26 









 
payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be
entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial
proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect
and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06,
incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall
be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding; provided, however, that the Trustee may be a member of a creditor’s or other similar committee. 
 All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any
trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 
 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to
represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver or rescission and annulment or for
any other reason or shall have been determined adversely to the Trustee, 

  
 27 









 
then and in every such case the Company, the Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights
hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though no such proceeding had been instituted. 
 Section 6.05. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the order following, at the
date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 

First, to the payment of all amounts due the Trustee under Section 7.06; 

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any
cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon
such overdue payments at the rate borne by the Notes plus one percent at such time, such payments to be made ratably to the Persons entitled thereto; 
 Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of the
Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has been collected by the
Trustee, upon overdue installments of interest at the rate borne by the Notes plus one percent at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment
of such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of
interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and
unpaid interest; and 
 Fourth, to the payment of the remainder, if any, to the Company. 

Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the
Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this
Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy
hereunder, unless: 
 (a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of
the continuance thereof, as hereinbefore provided; 

  
 28 









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

(d) the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity, shall have neglected or refused
to institute any such action, suit or proceeding; and 
 (e) no direction that, in the opinion of the Trustee, is inconsistent
with such written request shall have been given to the Trustee by the Holders of a majority in 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 this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and
enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the
Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this
Indenture, or to 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. 

Section 6.07. Proceedings by Trustee. In case of an Event of Default the Trustee may proceed to protect and enforce the rights
vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific
enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

Section 6.08. Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.06, all powers and
remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes,
by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any 

  
 29 









 
Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such
Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often
as shall be deemed expedient, by the Trustee or by the Holders. 
 Section 6.09. Direction of Proceedings and Waiver of
Defaults by Majority of Holders. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or
with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that would involve the Trustee in personal liability.
The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, including any Holders whose consents were obtained in connection with repurchases, tender offers or
exchanges of the Notes, may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal
(including any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to deliver the consideration due upon conversion of the Notes or
(iii) a default in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders
of the Notes shall be restored to their former positions and rights hereunder, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default
hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend
to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 Section 6.10. Notice of
Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, mail to all Holders as the names and addresses of such Holders appear upon the Note Register,
notice of all Defaults actually known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of
(including the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding
such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders. 

Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this 

  
 30 









 
Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and
that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such
party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if
any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price with respect to the Notes being repurchased as provided in this Indenture) 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 12. 
 ARTICLE 7 

CONCERNING THE TRUSTEE 

Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the
curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred that has not been cured or waived the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such
Holders have offered to the Trustee reasonable indemnity or security against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own
grossly negligent failure to act or its own willful misconduct, except that: 
 (a) prior to the occurrence of an Event of
Default and after the curing or waiving of all Events of Default that may have occurred: 
 (i) the duties and
obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no
implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (ii) in the
absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished


  
 31 









 
to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished
to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts
stated therein); 
 (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or
Responsible Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 
 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a majority in principal
amount of the Notes at the time outstanding determined as provided in Section 8.04 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under this Indenture; 
 (d) whether or not therein provided, every provision of this Indenture relating to the conduct
or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section 7.01 and to the provisions of the Trust Indenture Act; 

(e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other
matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to the Notes; 
 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure
to receive such notice as reason to act as if no such event occurred, unless such Responsible Officer of the Trustee had actual knowledge of such event; 
 (g) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest bearing trust account, and in no event shall the Trustee be liable
for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or the failure of the party directing such investments prior to its
maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment
direction from the Company; and 
 (h) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent,
Conversion Agent, Bid Solicitation Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid
Solicitation Agent or transfer agent. 

  
 32 









 None of the provisions contained in this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. Before taking or failing to take any action, the Trustee may require indemnity reasonably
satisfactory to it and the reasonable assurance as to repayment of funds. 
 Section 7.02. Reliance on Documents, Opinions,
Etc. Except as otherwise provided in Section 7.01: 
 (a) the Trustee may conclusively rely and shall be fully
protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, Note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties; 
 (b) any request, direction, order or demand of the Company mentioned herein shall
be sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an
Assistant Secretary of the Company; 
 (c) the Trustee may consult with counsel and require an Opinion of Counsel including
without limitation prior to taking any action hereunder at the expense of the Company and any advice of such counsel or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it
hereunder in good faith and in accordance with such advice or Opinion of Counsel; 
 (d) the Trustee shall not be bound to make
any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion,
may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the
Company, personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation; 
 (e) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney appointed by it with due care hereunder; and 
 (f) the permissive rights of the Trustee enumerated herein shall not be construed as duties. 
 In no event shall the Trustee be liable for any consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of
such loss or damage and regardless of the form of action. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such
Default or Event of Default 

  
 33 









 
or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or by any Holder of the Notes. 

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

Section 7.04. Trustee, Paying Agents, Conversion Agents, Bid Solicitation Agent or Note Registrar May Own Notes. The Trustee, any
Paying Agent, any Conversion Agent, Bid Solicitation Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying Agent, Conversion
Agent, Bid Solicitation Agent or Note Registrar. However, the Trustee shall comply with Sections 7.08 and 7.13. 
 Section
7.05. Monies and Shares of Common Stock to Be Held in Trust. All monies and shares of Common Stock received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money
and shares of Common Stock held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money or shares of Common Stock received by
it hereunder. 
 Section 7.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the
Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an
express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the
Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except
any such expense, disbursement or advance as shall have been caused by its gross negligence, willful misconduct or bad faith. The Company also covenants to indemnify and hold harmless the Trustee in any capacity under this Indenture and any other
document or transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without gross negligence, willful misconduct or
bad faith on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other
capacity hereunder, including the costs and expenses of defending themselves against any claim of liability. The obligation of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier
resignation or removal of the Trustee such additional indebtedness shall be a senior claim to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders,


  
 34 









 
and the Notes are hereby subordinated to such senior claim. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The
indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of
Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. 

Section 7.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 7.01, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the
Trustee, and such Officers’ Certificate, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the
provisions of this Indenture upon the faith thereof. 
 Section 7.08. Eligibility of Trustee. There shall at all times be
a Trustee hereunder which shall satisfy the requirements of Trust Indenture Act Section 310(a) and shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least
$50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Trustee shall comply with Trust Indenture Act Section 310(b), including the optional provision permitted by the second
sentence of Trust Indenture Act Section 310(b)(9); provided, however, that there shall be excluded from the operation of Trust Indenture Act §310(b)(1) any indenture or indentures under which other securities or certificates
of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Trust Indenture Act §310(b)(1) are met. If at any time the Trustee shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 7.09. Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the Holders
at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one
copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of
resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the 

  
 35 









 
appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11, on behalf of
himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

(b) In case at any time any of the following shall occur: 

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign
after written request therefor by the Company or by any such Holder, or 
 (ii) the Trustee shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, 
 then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of
Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

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

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this
Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 
 Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall,
upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such 

  
 36 









 
successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or
collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06. 

No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor
trustee shall be eligible under the provisions of Section 7.08. 
 Upon acceptance of appointment by a successor trustee as
provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Holders at their
addresses as they shall appear on the Note Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the
Company. 
 Section 7.11. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged
or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially
all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties
hereto; provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of
Section 7.08. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture,
any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver
such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of
any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall
have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation. 
 Section 7.12. Trustee’s Application for Instructions from the Company. Any
application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at
the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or 

  
 37 









 
after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal
included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any Officer that the Company has indicated to the Trustee should receive such application actually
receives such application, unless any such Officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written
instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 

Section 7.13. Preferential Collection of Claims. The Trustee shall comply with Trust Indenture Act Section 311(a), excluding
any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated. 

Section 7.14. Reports by Trustee to Holders. Within 60 days after each August 1, beginning with August 1, 2011, the
Trustee shall mail to each Holder, as provided in Trust Indenture Act Section 313(c), a brief report dated as of such August 1, if required by Trust Indenture Act Section 313(a), and file such reports with each stock exchange upon
which the Notes are listed and with the Commission as required by Trust Indenture Act Section 313(d). 
 ARTICLE 8

 CONCERNING THE HOLDERS 

Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate
principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of
such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of the Holders
voting in favor thereof at any meeting of Holders duly called and held, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any
action by the Holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if one is selected
shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 
 Section 8.02. Proof
of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. 

Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion
Agent and any Note Registrar may

deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and
notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03) accrued
and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary.
All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies
payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any Holder of a beneficial interest in a Global Note may directly enforce against the Company,
without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of
this Indenture. 
 Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the requisite
aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any
such direction, consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this
Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee solely in reliance on an Opinion of Counsel the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company or a Person
directly or indirectly controlling or controlled by or under direct or indirect common control with 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 Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above
described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for
the purpose of any such determination. 
 Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior
to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action,
any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such 

  
 39 









 
Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any
notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof. 
 ARTICLE 9 
 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 an indenture or indentures supplemental hereto for one or more of the following purposes: 

(a) to cure any ambiguity, omission, defect or inconsistency that does not adversely affect Holders of the Notes;

(j) to make any change that does not adversely affect the rights of any Holder; or 

(k) to conform the provisions of this Indenture or the Notes to the “Description of notes” section of the Prospectus.

 Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any
such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may, enter into any supplemental indenture that affects the Trustee’s own
rights, duties or immunities under this Indenture or otherwise. 

  
 40 









 Any supplemental indenture 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. 

The Trustee shall be entitled to rely on an Opinion of Counsel (which in turn may rely upon an Officers’ Certificate) for the
purpose of determining whether the entering into of a supplemental indenture for the purposes stated in clauses (a) or (j) of this Section 9.01 adversely affects the rights of any Holder or the Holders of the Notes. 

Section 9.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8) of the
Holders of at least a majority in aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer
for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture 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; 
 (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; 

(e) reduce the Redemption Price, the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse to the
Holders the Company’s obligation to make such payments, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise; 
 (f) make any Note payable in money 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 of and interest,
including Additional Interest, if any, 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 Notes; or 

(i) make any change in this Article 9 that requires each Holder’s consent or in the waiver provisions in Section 6.02 or
Section 6.09. 
 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent
of Holders as aforesaid and subject to Section 9.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental 

  
 41 









 
indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may, but shall not be obligated to, enter into such supplemental
indenture. 
 Holders do not need under this Section 9.02 to approve the particular form of any proposed supplemental
indenture. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental indenture. However, the
failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 
 Section 9.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 9, this Indenture shall be and be deemed to be modified
and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder
subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

Section 9.04. Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to
the provisions of this Article 9 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so
modified as to conform, in the opinion of the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the
Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 15.14) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 

Section 9.05. Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by
Section 15.09, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Indenture complies with the requirements of this Article 9 and is
permitted or authorized by the Indenture. 
 Section 9.06. Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act. 
 ARTICLE 10

 CONSOLIDATION, MERGER, SALE, CONVEYANCE AND
LEASE 
 Section 10.01. Company May Consolidate, Etc. on Certain Terms. Without the consent of the
Holders, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless: 

  
 42 









 (a) the resulting, surviving or transferee Person (the “Successor
Company”), if not the Company, is a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia; 
 (b) the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company under the Notes and this Indenture; 

(c) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this
Indenture; 
 (d) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel each stating that
such consolidation, merger, sale, conveyance, transfer or lease and, if a supplemental indenture is required in connection therewith, such supplemental indenture comply with this Indenture. 

For purposes of this Section 10.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets
of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated
basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 
 Section 10.02. Successor Corporation to Be Substituted. Upon the consummation of any transaction effected in accordance with this Article 10, if the Company is not the Successor Company, the
Successor Company shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture and the Notes with the same effect as if the Successor Company had been named as the Company in this Indenture.
Upon such substitution, except in the case of a lease, unless the Successor Company is one or more of the Company’s Subsidiaries, the Company will be released from its obligations under the Notes and this Indenture. 

ARTICLE 11 

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 this
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 corporation, either directly or through the Company or any successor corporation, 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 this Indenture and the issue of the Notes. 

  
 43 









 ARTICLE 12 
 CONVERSION OF NOTES 
 Section
12.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 12, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be
converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section 12.01(b), at any time prior to the close of business on the Business Day immediately
preceding November 1, 2017 under the circumstances and during the periods set forth in Section 12.01(b), and (ii) irrespective of the conditions described in Section 12.01(b), on or after November 1, 2017 and prior to the
close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 86.6739 shares of Common Stock (subject to adjustment as provided in Section 12.04, the
“Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 12.02, the “Conversion Obligation”). 

(b) (i) Prior to the close of business on the Business Day immediately preceding November 1, 2017, the Notes may be surrendered 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 (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading Day. The
Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other
than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent (if other than
the Company) shall have no obligation to 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) unless a Holder 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 for each Trading Day during the Measurement Period. At such 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
Note is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation
Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such
determination, or (y) the Company is acting as Bid Solicitation Agent and the Company 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


  
 44 









 
than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been
met, 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 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). The Company shall initially act as the Bid Solicitation Agent. The Company may appoint a nationally recognized securities dealer to act as Bid Solicitation Agent. 

(ii) If, prior to the close of business on the Business Day immediately preceding November 1, 2017, the Company
elects to: 
 (A) issue 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 announcement date of such issuance, 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 date of announcement of such issuance; or 

(B) distribute to all or substantially all holders of its Common Stock the Company’s assets, debt 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 preceding the date of
announcement for such distribution, 
 then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion
Agent (if other than the Trustee) at least 25 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, the Notes may be surrendered 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. 
 Notwithstanding the foregoing, Holders may not surrender Notes for conversion under this
Section 12.01(b)(ii) if Holders of the Notes are entitled to participate (as a result of holding the Notes), at the same time and upon the same terms as holders of the Common Stock, in such transaction without having to convert their Notes as
if such Holders held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the aggregate principal amount (expressed in thousands) of Notes held by such Holder. 

(iii) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change that does not
constitute a Fundamental Change occurs prior to the close of business on the Business Day immediately preceding November 1, 2017, 

  
 45 









 
regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 13.01, or if the Company is a party to a consolidation, merger, binding share
exchange, or transfer or lease of all or substantially all of its assets, pursuant to which the Common Stock would be converted into cash, securities or other assets, the Notes may be surrendered for conversion at any time from or after the date
that is 30 Scheduled Trading Days prior to the anticipated effective date of the transaction or event (or, if later, the Business Day after the Company gives notice of such transaction or event) until 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. 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, except as provided in clause (ii) below, less than 30 Scheduled Trading Days prior to the anticipated effective
date of such transaction or (ii) if the Company does not have knowledge of such transaction or event or has not entered into a definitive agreement with respect to such transaction to which the Company is a party at least 30 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 or event or enters into a definitive agreement with respect
to such transaction, but in no event later than the actual effective date of such transaction or event. 
 (iv)
Prior to the close of business on the Business Day immediately preceding November 1, 2017, the Notes may be surrendered for conversion during any calendar quarter commencing after March 31, 2011 (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
or equal to 130% of the Conversion Price on each applicable Trading Day. The Conversion Agent, on behalf of the Company, shall determine at the beginning of each calendar quarter commencing after March 31, 2011 whether the Notes may be
surrendered for conversion in accordance with this clause (iv) and shall notify the Company and the Trustee if the Notes become convertible in accordance with this clause (iv). 

(v) If the Company calls any or all of the Notes for redemption pursuant to Article 14 prior to the close of business on
the Business Day immediately preceding November 1, 2017, then Holders may convert Notes that have been so called for redemption at any time prior to the close of business on the Scheduled Trading Day prior to the Redemption Date, even if the
Notes are not otherwise convertible at such time. After that time, the right to convert shall expire, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert its Notes until the Redemption
Price has been paid or duly provided for. 
 Section 12.02. Conversion Procedure; Settlement Upon Conversion. 

(a) Subject to the other provisions of this Section 12.02 and to Section 12.03(b) and Section 12.07(a), upon conversion of
any Note, the Company shall pay or deliver, as the case 

  
 46 









 
may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if
applicable, in lieu of any fractional share of Common Stock in accordance with subsection (j) of this Section 12.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if
applicable, in lieu of any fractional share of Common Stock in accordance with subsection (j) of this Section 12.02 (“Combination Settlement”), at its election, as set forth in this Section 12.02. In addition, in
respect of conversions pursuant to Section 12.01(b)(iii), the Company shall pay to the converting Holder accrued and unpaid interest to, but not including, the Conversion Date (unless the Conversion Date falls after a Regular Record Date but on
or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to the Holder of record on such Regular Record Date and the Conversion
Obligation shall not include accrued and unpaid interest to, but not including, the Conversion Date). 
 (i) All
conversions occurring on or after November 1, 2017 and all conversions occurring after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date shall be settled using the same
Settlement Method. 
 (ii) Prior to November 1, 2017, except for any conversions that occur after the
Company’s issuance of a Redemption Notice with respect to the Notes but prior to the related Redemption Date, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not
have any obligation to use the same Settlement Method with respect to conversions that occur on different Trading Days. 
 (iii) If, in respect of any Conversion Date (or the period beginning on, and including, November 1, 2017 and ending on, and including, the second Scheduled Trading Day immediately preceding the
Maturity Date, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the
Trustee, shall deliver such Settlement Notice to converting Holders no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions occurring (x) after the date of
issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date, in such Redemption Notice or (y) on or after November 1, 2017, no later than November 1, 2017). Such Settlement Notice shall specify
the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company does not elect a Settlement Method prior to the deadline set forth in
the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the
Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar
Amount in such Settlement Notice, the Specified Dollar Amount shall be deemed to be $1,000. 

  
 47 









 (iv) The cash, shares of Common Stock or combination of cash and shares of
Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 
 (A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal
amount of Notes being converted a number of shares of Common Stock equal to the Conversion Rate (and cash in lieu of any fractional share of Common Stock); 
 (B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount
of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 20 consecutive Trading Days during the related Observation Period; and 

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such
conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20
consecutive Trading Days during the related Observation Period. 
 (v) The Daily Settlement Amounts (if
applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion
Values, as the case may be, and the amount of cash payable in lieu of any fractional share, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as
the case may be, and the amount of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent shall have no responsibility for any such determination. 

(b) Subject to Section 12.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder
shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to 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 and manually sign the irrevocable notice set forth on the back of the Note (a “Notice of Conversion”) (or a facsimile thereof), (2) deliver the Notice of Conversion and
the Note to the Conversion Agent at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) 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 12 on the Conversion Date for such conversion. No Notice of Conversion with respect to any
Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and not 

  
 48 









 
validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 13.02. The conversion of a beneficial interest in a Global Note shall be effected through the
Depositary (but not the Trustee or the Custodian) in accordance with this Indenture and the procedures of the Depositary therefor. Before the holder of a beneficial interest in a Global Note shall be entitled to convert, all or a portion of such
holder’s beneficial interest, such holder shall (i) comply with the procedures of the Depositary and if required, pay funds equal to interest payable on the next Interest Payment Date as set forth in Section 12.02(h). 

If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such
Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 
 (c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the Holder has complied with the requirements set
forth in subsection (b) above. The Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation, including any accrued and unpaid interest in respect of conversions pursuant to
Section 12.01(b)(iii) 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 Trading Day of the Observation Period, in
the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees,
certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation. 

(d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and
deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service
charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the
name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 
 (e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax
is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock
being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence. 

(f) Except as provided in Section 12.04, no adjustment shall be made for dividends on any shares issued upon the conversion of any
Note as provided in this Article 13.

 (g) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at
the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent
other than the Trustee. 
 (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid
interest, if any, except as set forth below and as set forth in Section 12.02(a). In any case in which a Holder does not receive a separate cash payment for accrued and unpaid interest upon conversion of its Notes, the Company’s settlement
of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest, if
any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will
be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular
Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record
Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1) for
conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date;
(3) for conversions pursuant to Section 12.01(b)(iii); (4) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or
(5) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note. 
 (i) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the close of business on the relevant
Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination
Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion. 
 (j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion based
on the Daily VWAP on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for
conversion, if the Company has elected Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Observation Period and
any fractional shares remaining after such computation shall be paid in cash.

 Section 12.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in
Connection with Make-Whole Fundamental Changes. (a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances
described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. The Company shall pay to the converting Holder
accrued and unpaid interest to, but not including, the Conversion Date (unless the Conversion Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company
shall instead pay the full amount of accrued and unpaid interest to the Holder of record on such Regular Record Date and the consideration due upon conversion will not include accrued and unpaid interest to, but not including, the Conversion Date).
A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the 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, 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; 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 is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, in addition to any accrued and unpaid interest to, but not including, the Conversion Date pursuant to
Section 12.02(a), the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate
(including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the
Holders of Notes 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. 

(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 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. The Board of Directors shall make appropriate 

  
 51 









 
adjustments to the Stock Price, in its good faith determination and without duplication, 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 of the event occurs, during such five consecutive Trading Day period. 
 (d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall
equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator
of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 12.04. 

(e) The following table sets forth the number of Additional Shares to be received 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, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for
the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year; 
 (ii) if the Stock Price is greater than $60.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection
(d) above), no Additional Shares shall be added to the Conversion Rate; and 
 (iii) if the Stock Price is
less than $9.23 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.


  
 52 









 Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon
conversion exceed 108.3424 per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 12.04. 
 (f) Nothing in this Section 12.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 12.04 in respect of a Make-Whole Fundamental Change. 

Section 12.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the
following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a share split or share combination), at the same time and upon the same terms as
holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 12.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the
Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 
 (a) If the
Company exclusively issues shares of Common Stock as a dividend or distribution on shares of its Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall 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 share split or share combination, as applicable;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or effective date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date; and
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.


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

  
 53 









 (b) If the Company issues to all holders of its Common Stock or, if one or more holders of its Common Stock
have waived their receipt of such rights, options or warrants, 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 announcement date of such
issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula: 
  

					
	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 issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale
Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.


Any increase made under this Section 12.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become
effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent such rights, options or warrants expire without delivery of shares of Common Stock, the Conversion Rate shall be decreased to the Conversion
Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or
warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such announcement with respect to the issuance of the rights, options or warrants had not occurred. 

For purposes of this Section 12.04(b) and Section 12.01(b)(ii)(A), in determining whether any rights, options or warrants
entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock 

  
 54 









 
for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering
price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if
other than cash, to be determined by the Board of Directors. 
 (c) If the Company distributes shares of its Capital Stock,
evidences of its indebtedness, other assets or property or rights, options or warrants to acquire its Capital Stock or other securities, to all or, if one or more holders of Common Stock have waived their receipt of such distribution, substantially
all holders of the 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 (any of such shares of Capital Stock, evidences of
indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall 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 Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for
such distribution.

 Any increase made under the portion of this Section 12.04(c) above shall become
effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such dividend
or distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each
$1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount of Distributed Property such Holder would have received if such Holder owned a number of shares of
Common Stock equal 

  
 55 









 
to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this
Section 12.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over
the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution. 
 With respect to an adjustment pursuant to this Section 12.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the
Conversion Rate shall be increased based on the following formula: 
  

					
	 CR1 = CR0  ×
	  	 FMV0 + MP0
	  	
	  	       
MP0	  	

 where, 
  

					
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	 	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common
Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the 10 consecutive Trading Day period
beginning on, and including, the fifth Trading Day immediately following the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
			
	MP0	 	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the Valuation Period; provided that in respect of any conversion during the Valuation
Period, references in the portion of this Section 12.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the fifth Trading Day immediately following the
Ex-Dividend Date of such Spin-Off and the Conversion Date in determining the Conversion Rate; and provided further that in respect of any conversion during the period between the Ex-Dividend Date of such Spin-Off and the fifth Trading Day
immediately following such Ex-Dividend Date, the Conversion Rate shall be adjusted on the first Trading Day of the Valuation Period and the settlement of such conversion shall be delayed by a number of Trading Days equal to length of such delay.


  
 56 









 For purposes of this Section 12.04(c) (and subject in all respect to
Section 13.11), rights, options or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under
certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not
exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 12.04(c) (and no adjustment to the Conversion Rate under this
Section 12.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate
shall be made under this Section 12.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such
rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend
Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the
event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a
distribution amount for which an adjustment to the Conversion Rate under this Section 12.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders
thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such
distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options
or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired
or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of Section 12.04(a), Section 12.04(b) and this Section 12.04(c), any dividend or distribution to which this Section 12.04(c) is applicable that also includes one or both
of: 
 (A) a dividend or distribution of shares of Common Stock to which Section 12.04(a) is applicable (the
“Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which
Section 12.04(b) is applicable (the “Clause B Distribution”), 
 then (1) such dividend or distribution, other than
the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 12.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by
this 

  
 57 









 
Section 12.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the
Clause C Distribution and any Conversion Rate adjustment required by Section 12.04(a) and Section 12.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the
Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be
“outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date” within the meaning of Section 12.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date”
within the meaning of Section 12.04(b). 
 (d) If any cash dividend or distribution is made to all or, if one or more
holders of Common Stock have waived their receipt of such dividend or distribution, substantially all holders of the Common Stock, the Conversion Rate shall be adjusted based on the following formula: 

 

					
	CR0
 = CR1 ×	 	 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 distributes to holders of its Common Stock.

 Any increase pursuant to this Section 12.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or
distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000
principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion
Rate on the Ex-Dividend Date for such cash dividend or distribution. 
 (e) If the Company or any of its Subsidiaries make a
payment in respect of a tender or exchange offer for the Common Stock, to the extent that the cash and value of any other 

  
 58 









 
consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or
exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  

					
	 CR1 = CR0 ×
	 	 AC+(SP1×OS1)
	  	
	 	OSO×SP1
	  	

 where, 
  

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

 The adjustment to the Conversion Rate under this Section 12.04(e) shall occur at the
close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the 10 Trading Days immediately
following, and including, the expiration date of any tender or exchange offer, references in this Section 12.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date
that such tender or exchange offer expires and the Conversion Date in determining the Conversion Rate. 
 (f) Notwithstanding
this Section 12.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a 

  
 59 









 
Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the
related Conversion Date as described under Section 12.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 12.04, the Conversion Rate
adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the
related dividend, distribution or other event giving rise to such adjustment. 
 (g) Except as stated herein, the Company shall
not adjust the Conversion Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or such convertible or exchangeable
securities. 
 (h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this
Section 12.04, and to the extent permitted by applicable law and subject to the applicable rules of The NASDAQ Global Market, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days
if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock
or rights to purchase Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall
mail to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and
the period during which it will be in effect. 
 (i) Notwithstanding anything to the contrary in this Article 12, the Conversion
Rate shall not be adjusted: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present or
future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present
or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries; 
 (iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection
and outstanding as of the date the Notes were first issued; 
 (iv) solely for a change in the par value of the
Common Stock; or 

  
 60 









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

(j) All calculations and other determinations under this Article 12 shall be made by the Company and shall be made to the nearest one-ten
thousandth (1/10,000) of a share. 
 (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall
promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ 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 Officers’ 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 Note Register of this Indenture. Failure to deliver such notice shall not affect the legality or validity of
any such adjustment. 
 (l) For purposes of this Section 12.04, the number of shares of Common Stock at any time
outstanding shall not include shares 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 issuable in
respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 (m) Notwithstanding anything in this
Section 12.04 to the contrary, the Company shall not be required to adjust the Conversion Rate unless the adjustment would result in a change of at least 1% of such Conversion Rate. However, the Company shall carry forward any adjustments that
are less than 1% of such Conversion Rate and take them into account when determining subsequent adjustments. In addition, the Company shall make any carry forward adjustments not otherwise effected on each anniversary of the first issue date of the
Notes, upon conversion of the Notes, upon required repurchases of the Notes in connection with a Fundamental Change and on the Maturity Date. 
 Section 12.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the
Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments 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 of the event occurs, at any time during the period when the Last Reported Sale
Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 
 Section 12.06.
Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as
such Notes 

  
 61 









 
are presented for conversion (assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement is applicable).

 Section 12.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 

(a) In the case of: 
 (i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination), 

(ii) any consolidation, merger or combination involving the Company, 

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

in each case as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets
(including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to
convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion
Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of Reference Property that a
holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, 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(j) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger 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 the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated
based on the value of a unit of Reference Property. 
 If the Merger Event causes the Common Stock to be converted into, or
exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be the
weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (ii) the unit of 

  
 62 









 
Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments that shall be as nearly
equivalent as is possible to the adjustments provided for in this Article 12. If, in the case of any Merger 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 successor or purchasing corporation, as the case may be, in such Merger 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. 
 (b) In
the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 12.07, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind
or amount of cash, securities or property or assets that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly
mail notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after
execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

(c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 12.07. None of the
foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 12.01 and Section 12.02
prior to the effective date of such Merger Event. 
 (d) The above provisions of this Section shall similarly apply to
successive Merger Events. 
 Section 12.08. Certain Covenants. (a) The Company covenants that all shares of Common
Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 
 (b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any
federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be. 

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

  
 63 









 Section 12.09. Responsibility of Trustee. The Trustee and any other Conversion Agent
shall not at any time be under any duty, responsibility or liability to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion
Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other
Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any
Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common
Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without
limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to
Section 12.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 12.07 or to any
adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officers’ Certificate and the Opinion of Counsel (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion
Agent shall be responsible for determining whether any event contemplated by Section 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 the notices referred to in Section 12.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to
deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 12.01(b). 

Section 12.10. Notice to Holders Prior to Certain Actions. In case of any: 

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to
Section 12.04 or Section 12.11; 
 (b) Merger Event; or 

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

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be
filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to


  
 64 









 
the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a
record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution,
liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon
such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation
or winding-up. 
 Section 12.11. Stockholder Rights Plans. To the extent that the Company has a rights plan in effect
upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. If prior to the time of conversion, however, the rights have separated from the shares of
Common Stock in accordance with the provisions of the applicable stockholder rights plan so that the Holders would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon conversion of the Notes, the Conversion Rate
shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of Common Stock shares of Capital Stock of the Company, evidences of its indebtedness, other assets or property or rights, options or
warrants to acquire its 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. 

Section 12.12. Withholding Taxes for Adjustments in Conversion Rate. The Company may, at its option, set-off withholding taxes due
with respect to Notes against payments of Cash and Common Stock on the Notes. In the case of any such set-off against Common Stock delivered upon conversion of the Notes, such Common Stock shall be valued based on the arithmetic average of the
Last Reported Sales Price of the Common Stock for each of the last 20 Trading Days immediately preceding the date of payment of Common Stock on the Notes. 
 ARTICLE 13 
 REPURCHASES 

Section 13.01. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time,
each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the
“Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of
the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls
after a 

  
 65 









 
Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid
interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 13. 

(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”) 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 (together with all necessary endorsements for
transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the
Holder of the Fundamental Change Repurchase Price therefor. 
 The Fundamental Change Repurchase Notice in respect of any Notes
to be repurchased shall state: 
 (i) in the case of Physical Notes, the certificate numbers of the Notes to be
delivered for repurchase; 
 (ii) the portion of the principal amount of Notes to be repurchased, which must be
$1,000 or an integral multiple thereof; and 
 (iii) that the Notes are to be repurchased by the Company pursuant
to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the
Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to
the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 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. 

  
 66 









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

(i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 13; 

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

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

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

(viii) if applicable, that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a
Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; 
 (ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes
pursuant to this Section 13.01. 
 At the Company’s request, the Trustee shall give such notice in the Company’s
name and at the Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company and the Trustee shall have no liability for the content thereof. 

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental
Change if the principal amount of the 

  
 67 









 
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). 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, and any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed
to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 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 Corporate Trust Office of 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, 
 (ii) if Physical Notes have been
issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted, and 

(iii) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase
Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that if the
Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary. 
 Section 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 4.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price.
Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date 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 Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee
shall, promptly 

  
 68 









 
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 (i) such Notes will cease to be outstanding, (ii) interest will cease to
accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to
receive the Fundamental Change Repurchase Price). 
 (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 successor or similar schedule; 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 13 to be exercised in the time and in the manner specified in
this Article 13. 
 ARTICLE 14 
 OPTIONAL REDEMPTION 
 Section 14.01. Optional
Redemption. No sinking fund is provided for the Notes. The Notes shall not be redeemable by the Company prior to February 1, 2015. On or after February 1, 2015, the Company may redeem (an “Optional Redemption”) for
cash all or part of the Notes, upon notice as set forth in Section 14.02, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date
(the “Redemption Price”) (unless the Redemption Date falls after a Regular Record Date but on or prior to the immediately succeeding Interest Payment Date, in which case interest accrued to the Interest Payment Date will be paid to
Holders of record of such Notes on such Regular Record Date, and the Redemption Price will be equal to 100% of the principal amount of the Notes to be redeemed). 

  
 69 









 Section 14.02. Notice of Optional Redemption; Selection of Notes. 

(a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may be, any part of the Notes pursuant to
Section 14.01, it shall fix a date for redemption (each, a “Redemption Date”) and it shall or, at its written request received by the Trustee not less than 40 calendar days prior to the Redemption Date (or such shorter period
of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall mail or cause to be mailed a notice of such Optional Redemption (a “Redemption Notice”) not less than 30 nor more
than 60 calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole or in part at its last address as the same appears on the Note Register; provided, however, that if the Company shall give such
notice, it shall also give written notice of the Redemption Date to the Trustee and the Paying Agent. 
 (b) The Redemption
Notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail or any defect in the Redemption
Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. 
 (c) Each Redemption Notice shall specify: 
 (i) the Redemption Date
(which must be a Business Day); 
 (ii) the Redemption Price; 

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each such Note, and that interest
thereon, if any, shall cease to accrue on and after said date; 
 (iv) the place or places where such Notes are
to be surrendered for payment of the Redemption Price; 
 (v) that Holders may surrender their Notes for
conversion at any time prior to the close of business on the Scheduled Trading Day immediately preceding the Redemption Date; 
 (vi) the procedures a converting Holder must follow to convert its Notes and the Settlement Method and Specified Dollar Amount, if applicable; 

(vii) the Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance
with Section 12.03; 
 (viii) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes; and

 (ix) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be
redeemed and on and after the Redemption Date, upon surrender of 

  
 70 









 
such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 
 A Redemption Notice shall not be revocable. 
 (d) If fewer than all of the
outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of a Global Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis
or by another method the Trustee considers to be fair and appropriate. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so far as
may be possible) to be the portion selected for redemption. In the event of any redemption in part, the Company will not be required to register the transfer of or exchange any Note so selected for redemption, in whole or in part, except for the
unredeemed portion of any Note being redeemed in part. 
 Section 14.03. Payment of Notes Called for Redemption.

 (a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 14.02, the Notes shall
become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes
shall be paid and redeemed by the Company at the applicable Redemption Price. 
 (b) Prior to the open of business on the
Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 7.05 an amount of cash (in immediately
available funds if deposited on the Redemption Date), sufficient to pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be
made promptly after the later of: 
 (i) the Redemption Date for such Notes; and 

(ii) the time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder
thereof in the manner required by this Section 14.03. 
 The Paying Agent shall, promptly after such payment and upon written demand by the
Company, return to the Company any funds in excess of the Redemption Price. 
 Section 14.04. Restrictions on Redemption.
The Company may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in
the case of an acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes).

Section 2.07, Section 9.04 and Section 13.03 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes. For all
purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the

successor corporation or other entity.

resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of

such appointment to the Company and shall mail notice of such appointment to all Holders as the names and addresses of such Holders appear on the Note Register. 
 The Company agrees to pay to the authenticating agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines such

 The provisions of Section 7.02, Section 7.03, Section 7.04,
Section 8.03 and this Section 15.14 shall be applicable to any authenticating agent. 
 If an authenticating agent is

counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 
 Section 15.16. Severability. In the event any provision of this Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or
enforceability of the remaining provisions shall not in any way be affected or impaired. 
 Section 15.17. Waiver of Jury
Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE
TRANSACTION CONTEMPLATED HEREBY. 

  
 75 









 Section 15.18. Force Majeure. In no event shall the Trustee be responsible or liable
for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism,
civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use
reasonable efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 
 Section 15.19. Calculations. Except as otherwise provided herein, the Company shall be responsible for making all calculations called for under the Notes and the Trustee and the Conversion Agent
shall have no liability therefor. These calculations include, but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock, accrued interest payable on the Notes and the Conversion Rate of the Notes. The Company shall
make all these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders of Notes. The Company shall provide a schedule of its calculations to each of the Trustee and the Conversion
Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder of
Notes upon the request of that Holder at the sole cost and expense of the Company.

 This Note shall bear interest on the

of, any Note therein shall be deemed to include Additional Interest if, in such context, Additional Interest is, was or would be payable pursuant to such Section 6.03 and any express mention of the payment of Additional Interest in any

 [FORM OF REVERSE OF NOTE] 

Savient Pharmaceuticals, Inc. 
 4.75% Convertible Senior Note due 2018 
 This Note is one of a duly authorized
issue of Notes of the Company, designated as its 4.75% Convertible Senior Notes due 2018 (the “Notes”), limited to the aggregate principal amount of $230,000,000 all issued or to be issued under and pursuant to an Indenture dated as
of February 4, 2011 (the “Indenture”), between the Company and U.S. BANK NATIONAL ASSOCIATION (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain
conditions specified in the Indenture. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be
continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. 
 Subject to the terms
and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to the
Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of
the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal (including the Fundamental Change Repurchase Price, if applicable) of and accrued and unpaid interest on this Note at the place, at the respective times, at the rate and in the
lawful money herein prescribed. 
 The Notes are issuable in registered form without coupons in denominations of $1,000
principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture,


  
 A-5









 
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 shall be redeemable at the Company’s option in accordance with the
terms and conditions specified in the Indenture. 
 Upon the occurrence of a Fundamental Change, the Holder has the right, at
such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal
to the Fundamental Change Repurchase Price. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at
its option, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion
thereof that is $1,000 or an integral multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as
provided in the Indenture. 
 Terms used in this Note and defined in the Indenture are used herein as therein defined.
