later than March 7, 2008, to review the terms of the revised plan and to determine if the new schedule and plan is mutually acceptable to both parties, or that a modified plan or an another alternative is agreeable (the “Revised

 2. Qualcomm agrees that any payment that is currently due, or scheduled to be paid by Aircell under the
Development Agreement, will be held in abeyance until the parties mutually agree to the Revised Plan. Such Revised Plan will detail such revised payment amounts and schedule payment dates[***]. Consummation of the Revised Plan shall occur on or
before March 14, 2008 
 3. Each party will pay its own expenses incurred in connection with the Revised Plan, including,

 5. That certain Mutual Nondisclosure Agreement among the parties dated February 7, 2007
(“Confidentiality Agreement”) shall continue to be binding upon the parties in accordance with its terms. 
 If the

Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed the

Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing. 
 No service charge shall
be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp
or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for
exchange or registration of transfer. 
 None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be
required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any Notes, or a portion of any Note,
surrendered for repurchase (and not withdrawn) in accordance with Article 15 or (iii) any Notes selected for redemption in accordance with Article 16. 
 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

(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

  
 15 

 
of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and
the procedures of the Depositary therefor.

shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the
Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c) and Section 2.05(d), the term “transfer”
encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 
 Until the date (the
“Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the last date of original issuance of the Notes, and (2) such later date, if any, on which the Company instructs the Trustee
in writing that the following restrictions will no longer apply, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which
shall bear the legend set forth in Section 2.05(d), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective
under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise

ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, AND (II) THAT IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY PRIOR TO THE RESALE RESTRICTION TERMINATION DATE, FURNISH TO THE TRUSTEE AND THE ISSUER SUCH
CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED PURSUANT TO THE INDENTURE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO 

  
 16 

 
AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 THE “RESALE RESTRICTION TERMINATION DATE” MEANS THE DATE: (1) THAT IS AT LEAST ONE YEAR AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE NOTES; AND (2) ON WHICH THE COMPANY HAS
INSTRUCTED THE TRUSTEE THAT THIS LEGEND WILL NO LONGER APPLY, IN ACCORDANCE WITH THE PROCEDURES DESCRIBED IN THE INDENTURE FOR THE NOTES. 
 No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been checked and such
certifications, legal opinions or other information as may be required by this Indenture or reasonably requested by the Company or the Trustee to confirm that the transfer of Notes complies with the foregoing restrictions. 

Any Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in
accordance with their terms may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which
shall not bear the restrictive legend required by this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the Custodian in writing to so surrender any Global Note as to which such
restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the
restrictive legend specified in this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the Resale Restriction Termination Date and promptly after a
registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act. 
 Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except (i) by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and
(ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of
the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.05(c). 

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. 

  
 17 

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

 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) shall be
registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, 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. 

(d) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of such Note
shall bear a legend in substantially the following form (unless the Note or such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be
effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon conversion of Notes that have been
transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144
or any similar provision then in force under 

  
 18 

 
the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent for the Common Stock): 

THE SALE OF THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), AND ACCORDINGLY, THIS SECURITY MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES THAT IT WILL NOT PRIOR TO THE RESALE RESTRICTION TERMINATION DATE, OFFER, RESELL,
PLEDGE OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY, EXCEPT (A) TO THE ISSUER; (B) UNDER A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT; (C) TO A PERSON THE SELLER REASONABLY BELIEVES IS A
QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF ANOTHER QUALIFIED INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN
RELIANCE ON RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE); OR (D) UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, AND AGREES THAT IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY PRIOR
TO THE RESALE RESTRICTION TERMINATION DATE, FURNISH TO THE TRANSFER AGENT AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 THE “RESALE RESTRICTION TERMINATION
DATE” MEANS THE DATE: (1) THAT IS AT LEAST ONE YEAR AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE COMPANY’S 2.25% CONVERTIBLE SENIOR NOTES DUE 2032; AND (2) ON WHICH THE COMPANY HAS INSTRUCTED THE TRANSFER AGENT THAT THIS
LEGEND WILL NO LONGER APPLY, IN ACCORDANCE WITH THE PROCEDURES DESCRIBED IN THE INDENTURE FOR THE NOTES. 
 Any such Common
Stock as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the Company’s
stock transfer agent for the Common Stock, and such certifications, legal opinions or other information as may be required by this Indenture or reasonably requested by the Company to confirm that the transfer of Common Stock complies with the
foregoing restrictions, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.05(d). 

(e) Any Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate of the
Company may not be resold by such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the
case may be, no longer being a “restricted security” (as defined under 

  
 19 

 
Rule 144 under the Securities Act). The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.08.

 Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed,
lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction,
loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such
security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent upon the
issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new
substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about
to be converted in accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the
conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating
agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory
to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost
or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations
set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive
with respect to the replacement 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. 

  
 20 

 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 surrendered 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 in accordance with its customary procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order. 

Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and,
if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as
printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

 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 and with the same CUSIP number as the Notes initially issued hereunder in an unlimited aggregate principal amount; provided that if any such
additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver
to the Trustee a Company Order, an 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 17.05, as the Trustee shall
reasonably request. In addition, the Company may, to the extent permitted by law, and 

  
 21 

 
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. 
 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 on the Maturity Date, any Repurchase Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or cash and shares of
Common Stock, if any (solely to satisfy the Company’s Conversion Obligation, if applicable), 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 relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding
the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive. 
 ARTICLE 4 
 PARTICULAR COVENANTS OF
THE COMPANY 
 Section 4.01. Payment of Principal and Interest. The Company covenants and
agrees that it will cause to be paid the principal (including the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in
the manner provided herein and in the Notes. 
 Section 4.02. Maintenance of Office or Agency. The Company will maintain
an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices
and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or
agency of the Trustee. 

  
 22 

 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 will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms
“Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 
 The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office and the office or agency of the Trustee in the
Borough of Manhattan, The City of New York, 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, will appoint, in the manner provided in
Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder. 
 Section 4.04. Provisions as to
Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to
the provisions of this Section 4.04: 
 (i) that it will hold all sums held by it as such agent for the
payment of the principal (including the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes; 

(ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal
(including the Repurchase Price and 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
Repurchase Price and 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 Repurchase Price and the Fundamental
Change Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on
the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date. 
 (b) If the
Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Repurchase Price and the Fundamental Change Repurchase 

  
 23 

 
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 Repurchase Price and 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 Repurchase Price and 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 Repurchase Price and 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 Repurchase Price and 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 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 11, the
Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 
 Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, for one year
after the date of latest original issuance of the Notes, promptly provide to the Trustee and shall, upon written request, provide to any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issuable upon
conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under the Securities Act. The Company
shall take such further action as any Holder or beneficial owner of 

  
 24 

 
such Notes or such Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in
accordance with Rule 144A under the Securities Act, as such rule may be amended from time to time. 
 (b) The Company shall file
with the Trustee within 15 days after the same are required to be filed with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving
effect to any grace period provided by Rule 12b-25 under the Exchange Act). 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(b) at the time such documents are filed via the EDGAR system. 
 (c) Delivery of the reports and
documents described in subsection (b) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information
contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officers’ Certificate). 

(d) If, at any time during the six-month period beginning on, and including, the date that is six months after the
last date of original issuance of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all
applicable grace periods thereunder and other than reports on Form 8-K), or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates (as a result of restrictions pursuant to U.S. securities laws or the terms of
this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.25% per annum and, beginning on the 91st day immediately following the first day the Company fails to file
such information, at a rate equal to 0.50% per annum, in each case, of the principal amount of the Notes outstanding for each day during such period for which the failure to file has occurred and is continuing. As used in this
Section 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the
Commission pursuant to Section 13 or 15(d) of the Exchange Act. 
 (e) If, and for so long as, the restrictive legend on
the Notes specified in Section 2.05(c) has not been removed, the Notes are assigned a restricted CUSIP or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates (without restrictions pursuant to U.S.
securities laws or the terms of this Indenture or the Notes) as of the 365th day after the last date of original issuance of the Notes, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal
amount of the Notes outstanding until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes have been assigned an unrestricted CUSIP and the Notes are freely tradable by Holders other than the
Company’s Affiliates (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes). 

  
 25 

 (f) Additional Interest will be payable in arrears on each Interest Payment Date following
accrual in the same manner as regular interest on the Notes. 
 (g) The Additional Interest that is payable in accordance with
Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03. 

(h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or Section 4.06(e), the Company shall deliver
to the Trustee an Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the
Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company
shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment. 
 Section 4.07.
Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or
usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the
covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 4.08. Compliance Certificate; Statements as to Defaults. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal
year ending on November 30, 2012) 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 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 is taking or proposing to take in respect thereof. 
 Section 4.09. Further
Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

to be furnished to the Trustee, semi-annually, not more than 15 days after each April 15 and October 15 in each year beginning with October 15, 2012, 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 Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no such list
need be furnished so long as the Trustee is acting as Note Registrar. 
 Section 5.02. Preservation and Disclosure of
Lists. The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders contained in the most recent list furnished to it as provided in Section 5.01 or maintained

ARTICLE 6 

DEFAULTS AND REMEDIES

 (a) default in any payment of interest on any Note when due and payable, and the default continues for a period of 30 days;

 (b) default in the payment of principal of any Note when due and payable on the Maturity Date, upon Optional Redemption, upon
any required repurchase, upon declaration of acceleration or otherwise; 
 (c) failure by the Company to comply with its
obligation to convert the Notes in accordance with this Indenture upon exercise of a Holder’s conversion right;

 (e)
failure by the Company to comply with its obligations under Article 11; 
 (f) failure by the Company for 60 days after written
notice from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding has been received by the Company to comply with any of its other agreements contained in the Notes or this Indenture; 

  
 27 

 (g) failure by the Company or any Significant Subsidiary of the Company to pay when due
(whether at stated maturity or otherwise), after the expiration of any applicable grace period, of principal of or interest on indebtedness for borrowed money, where the amount of such unpaid principal and/or interest is in an aggregate amount in
excess of $50 million or more (or a foreign currency equivalent), or a default that results in the acceleration of maturity of any indebtedness for borrowed money of the Company or any Significant Subsidiary of the Company in an aggregate amount in
excess of $50 million (or its foreign currency equivalent), in each cash, if both (i) such indebtedness is not discharged and (ii) such acceleration is not rescinded, stayed or annulled, within a period of 30 calendar days after written
notice of such failure is given to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in aggregate principal amount of the Notes then outstanding; 

(h) the Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or
other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or
other similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other
proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or 
 (i) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation, reorganization or other relief with respect to the Company or such
Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such
Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive days. 

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

  
 28 

 The immediately preceding paragraph, however, is subject to the conditions that if, at any
time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall
deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of
accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes 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, 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. 
 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 comply with its obligations as set forth in Section 4.06(a) and
Section 4.06(b) shall for the first 360 days after the occurrence of such an Event of Default consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to (i) 0.25% per annum of the principal amount
of the Notes outstanding for each day during the 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 and (ii) 0.50% per annum of the principal
amount of the Notes outstanding for each day during the 270-day period on which such Event or Default is continuing beginning on, and including, the 91st day following, and including, the date on which such an Event of Default first occurs. Additional Interest payable
pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e). 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 361st 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 361st 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 elected 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. 

  
 29 

 In order to elect to pay Additional Interest as the sole remedy during the first 360 days
after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 360-day period. Upon
the 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 payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to
the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of
the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or
its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee 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 

  
 30 

 
such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a
lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization
or arrangement or otherwise. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be
enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of
an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the
Notes. 
 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of
this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or
abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the
Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall
continue as though no such proceeding had been instituted. 
 Section 6.05. Application of Monies Collected by Trustee.
Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes,
and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the
payment of all amounts due the Trustee 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) 

  
 31 

 
upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto; 

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the
payment of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue
principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time plus one percent, and in case such monies shall be insufficient to pay in
full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of
principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the
Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and 
 Fourth, to
the payment of the remainder, if any, to the Company. 
 Section 6.06. Proceedings by Holders. Except to enforce the
right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have
any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator,
custodian or other similar official, or for any other remedy hereunder, unless: 
 (a) such Holder previously shall have given
to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided; 
 (b) Holders of at
least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 

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

  
 32 

 
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
Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or
provided for in such Note or in this Indenture, or to 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 in its
discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law. 
 Section 6.08. Remedies Cumulative and Continuing. Except as provided in the last
paragraph of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies
available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any
Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein;
and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the
Holders. 
 Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a
majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any 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 it determines is unduly prejudicial to the rights of any other Holder or that would involve the
Trustee in personal liability. The 

  
 33 

 
Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any
past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that has
not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or
provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. 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 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 Repurchase Price and 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 determines that the withholding of such notice is in the interests of the Holders. 
 Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its
discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to
pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the 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 14.

 ARTICLE 7 
 CONCERNING THE TRUSTEE 
 Section
7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties
as are specifically set forth in this Indenture. 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 indemnity or security satisfactory to it 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 to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or
opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not
confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 
 (b) the Trustee shall
not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 

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

  
 35 

 
any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 
 (d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of
this Section; 
 (e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to
receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent 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; 
 (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; and 
 (i) the Trustee is
not the Company’s stock transfer agent and shall have no duties or liability in connection with the Company’s obligations to issue Common Stock under this Indenture. 
 None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in
the exercise of any of its rights or powers. 
 Section 7.02. Reliance on Documents, Opinions, Etc. Except as otherwise
provided in Section 7.01: 
 (a) the Trustee may conclusively rely and shall be fully protected in acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, Note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or
parties; 

  
 36 

 (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 pursuant to
Section 17.05 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 other than any such loss or damage caused by the
Trustee’s willful misconduct or gross negligence. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such
Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or by any Holder of the Notes. 
 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 

  
 37 

 
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. 

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 except as may be agreed from time to time by the Company and the Trustee. 

Section 7.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and
the Trustee shall be entitled to, 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 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 Indenture or in any other capacity hereunder, including the costs and
expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and
advances shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the benefit of
the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The obligation of the Company under this
Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably
withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of
Default specified in Section 6.01(h) or Section 6.01(i) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. 

  
 38 

 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 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. 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 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 or
herself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

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

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

  
 39 

 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 or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

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

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

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor
trustee, at the written direction and at the expense of the Company shall 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 

  
 40 

 
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 after which such action shall be taken or such omission shall be effective. 

ARTICLE 8 

CONCERNING THE HOLDERS 

Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the
aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders.
Whenever the Company or the Trustee solicits the taking of any action by the Holders 

  
 41 

 
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 and Section 9.05, proof of the execution of any instrument by a Holder or its
agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note
Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06. 
 Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a
Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other
than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes;
and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments or deliveries so made to any Holder for the time being, or upon its
order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the
contrary in this Indenture or the Notes following an Event of Default, any Holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the
Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture. 

Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of
Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the
purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or a Person directly or
indirectly controlling or controlled by or under direct or indirect common control with the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying 

  
 42 

 
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 of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the evidence
to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as
concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution
therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

the latter to have attached thereto the ballots voted at the meeting. 
 Any record so signed and verified shall be conclusive
evidence of the matters therein stated. 
 Section 9.07. No Delay of Rights by Meeting. Nothing contained in this Article
9 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred

 Upon 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 in its discretion, enter into any supplemental indenture that affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any supplemental indenture authorized by
the provisions of this Section 10.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 

Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8) of the
Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange

 Upon the written request of the Company, and upon the

Holders do not need under this Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be
sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such

Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of
this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the

and conditions of this Indenture for any and all purposes. 
 Section 10.04. Notation on Notes. Notes authenticated and
delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental

delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 
 Section 10.05.

Indenture; and 
 (b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred
and be continuing under this Indenture. 
 For purposes of this Section 11.01, 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 11.02. Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or
lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on
all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by
the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it
had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either 

  
 48 

 
in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the
order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes
that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All
the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date
of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article 11 the Person named as the “Company” in the first paragraph of this
Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from
its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes. 
 In case of any
such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 

Section 11.03. Opinion of Counsel to Be Given to Trustee. No consolidation, merger, sale, conveyance, transfer or lease shall be
effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental
indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 11. 
 ARTICLE 12 
 IMMUNITY OF INCORPORATORS,
STOCKHOLDERS, OFFICERS AND DIRECTORS 
 Section 12.01. 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.

 ARTICLE 13 
 [INTENTIONALLY OMITTED] 
 ARTICLE 14 

CONVERSION OF NOTES 
 Section 14.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 14, each Holder of a Note shall have the right, at such Holder’s option, to
convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) at any time prior to the close of business on the Business Day immediately preceding February 1, 2032,
and other than during the period from, and including, February 1, 2017 to the close of business on the Business Day immediately preceding May 5, 2017, under the circumstances and only during the periods set forth in Section 14.01(b),
and (ii) irrespective of the conditions described in Section 14.01(b), during the period from, and including, February 1, 2017 to the close of business on the Business Day immediately preceding May 5, 2017, and on or after
February 1, 2032 and prior to the close of business on the Business Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 19.7750 shares of Common Stock (subject to adjustment as provided in this Article
14, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 14.02, the “Conversion Obligation”). 

(b) (i) Prior to the close of business on the Business Day (subject to any prior redemption or repurchase) immediately preceding
February 1, 2032, 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 of the two 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 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 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, at which time the Company
shall instruct the Bid Solicitation Agent to 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 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 

  
 50 

 
such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common
Stock and the Conversion Rate on each Trading Day of such failure. 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) that the Trading Price condition is no longer met. 

(ii) If, prior to the close of business on the Business Day immediately preceding February 1, 2032, 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 40 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. A Holder may not convert its Notes under this conversion provision upon the specified distributions above if such Holder will participate in such distribution as if such Holder had
converted its Notes immediately prior to such distribution. 
 (iii) If a transaction or event that constitutes a
Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding February 1, 2017, regardless of whether a Holder has the right to require the Company to repurchase the Notes
pursuant to Section 15.02, or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets, pursuant to which the Common Stock would

  
 51 

 
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 40 Scheduled Trading Days prior to the anticipated
effective date of the transaction (or, if later, the Business Day after the Company gives notice of such transaction) until 40 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental
Change, until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) (i) at least 40 Scheduled Trading Days prior to the anticipated effective date of
such transaction if the Company is a party to such transaction or (ii) if the Company is not a party to such transaction, within two Business Days of the date upon which the Company receives notice, or otherwise becomes aware, of such
transaction. 
 (iv) Prior to the close of business on the Business Day immediately preceding February 1,
2032, the Notes may be surrendered for conversion (subject to any prior redemption or repurchase) during any fiscal quarter commencing after the fiscal quarter ending on September 2, 2012 (and only during such fiscal quarter), if the Last
Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding fiscal quarter is greater than or equal to
130% of the Conversion Price on each applicable Trading Day. The Conversion Agent, on behalf of the Company, shall determine at the beginning of each fiscal quarter commencing after September 2, 2012 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 16, then Holders may surrender Notes
that have been so called for redemption at any time prior to the close of business on the Business 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 14.02. Conversion Procedure; Settlement Upon Conversion. 

(a) Except as provided in Section 14.03(b) and Section 14.07(a), upon conversion of any Note, on the third Business Day
immediately following the last Trading Day of the relevant Observation Period, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, a “Settlement
Amount” equal to the sum of the Daily Settlement Amounts for each of the 35 Trading Days during the applicable Observation Period for such Note, together with cash, if applicable, in lieu of any fractional share of Common Stock in
accordance with subsection (j) of this Section 14.02. 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 

  
 52 

 
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 (if
other than the Trustee) shall have no responsibility for any such determination. 
 (b) Subject to Section 14.02(e), before
any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest
payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion
Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name
or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the
Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal
to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this
Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Repurchase Notice or Fundamental Change Repurchase Notice to the
Company in respect of such Notes and not validly withdrawn such Repurchase Notice or Fundamental Change Repurchase Notice in accordance with Section 15.03. 
 If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal
amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 
 (c) A Note shall be
deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. 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. 

  
 53 

 (e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp
or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall
pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such
Holder in accordance with the immediately preceding sentence. 
 (f) Except as provided in Section 14.04, no adjustment
shall be made for dividends on any shares issued upon the conversion of any Note as provided in this Article 14. 
 (g) Upon the
conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the
Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee. 
 (h) Upon
conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the 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 relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to
be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes, 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 and prior to the open of business on the corresponding Interest Payment Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount
of interest payable on such Notes on 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) for conversions following the Regular Record Date immediately preceding May 5, 2017; (3) 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; (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 Defaulted Amounts, if any Defaulted Amounts 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 last Trading Day of the related Observation Period. 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 

  
 54 

 
Stock issuable upon conversion based on the Daily VWAP on the last Trading Day of the applicable Observation Period. The 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 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental
Changes. (a) If a Make-Whole Fundamental Change occurs prior to May 5, 2017 and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below,
increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for these purposes to be
“in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the
Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof,
the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). 
 (b) Upon surrender of
Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to Section 14.01(b)(iii), the Company shall satisfy the related Conversion Obligation in accordance with Section 14.02 based on the Conversion Rate as
increased to reflect the Additional Shares pursuant to the table below; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the
Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely
on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price.
In such event, the Conversion Obligation 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 in exchange for their Common Stock only
cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices
of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock
Price, in its good faith determination, to account 

  
 55 

 
for any adjustment or multiple adjustments 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 14.04. 
 (e) The
following table sets forth the number of Additional Shares of Common Stock to be received per $1,000 principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date set forth below:

 The exact Stock 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 $130.00 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 $33.16 per share (subject to adjustment in the same manner as the Stock Prices set
forth in the column headings of the table above 

  
 56 

 
pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 30.1568, subject to adjustment in the same manner as the Conversion Rate pursuant to
Section 14.04. 
 (f) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to
Section 14.04 in respect of a Make-Whole Fundamental Change. 
 Section 14.04. Adjustment of Conversion Rate. The
Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of 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 14.04, without having to convert their
Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on shares of 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: 
  

 
 where, 
  

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

 Any adjustment made under this Section 14.04(a) shall become effective immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this
Section 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective 

  
 57 

 
as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. 
 (b) If the Company issues to all or substantially all holders of 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 adjusted based on the following formula:

  
 

 
 where, 
  

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

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

 For purposes of this Section 14.04(b) and for the purpose of Section 14.01(b)(ii)(A), in determining whether any
rights, options or warrants entitle the holders to subscribe for or 

  
 58 

 
purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights,
options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
 (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property or rights, options or warrants to acquire its Capital Stock or other securities, to all
or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 14.04(a) or Section 14.04(b), (ii) rights issued to all holders of
the Common Stock pursuant to a rights plan, where such rights are not presently exercisable, continue to trade with the Common Stock and Holders will receive such rights together with any Common Stock upon conversion as described below,
(iii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 14.04(d), and (iv) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply
(any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion
Rate shall be increased based on the following formula: 
  
 

 
 where, 
  

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

 Any increase made under the portion of this Section 14.04(c) above shall become effective
immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had
not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing
increase, each Holder of a Note shall receive, in respect of each $1,000 

  
 59 

 
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 to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for
purposes of this Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the
Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution. 
 With respect to an adjustment pursuant to this Section 14.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the
Conversion Rate shall be increased based on the following formula: 
  
 

 
 where, 
  

					
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR’	 	=	 	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	 	=	 	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common
Stock over the first 10 consecutive Trading Day period immediately following, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
			
	MP0	 	=	 	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 Because the adjustment to the applicable Conversion Rate under the preceding paragraph will be made
immediately after the end of the Valuation Period for a Spin-Off, (i) if a Holder converts a Note and the first Trading Day of the Observation Period applicable to such Note occurs on or after the Ex-Dividend Date for a Spin-Off, but prior to
or on the last Trading Day of the Valuation Period for such Spin-Off, the Company will postpone the Conversion Date applicable to such Note until the first Business Day immediately following the last Trading Day of such Valuation Period (and the
settlement of such Note will be postponed accordingly), and (ii) if a Holder converts a Note, at least one Trading Day of the Observation Period applicable to such Note occurs prior to the Ex-Dividend Date for such Spin-Off and, but for this
provision, at least one Trading Day of such Observation Period would occur on or after the Ex-Dividend Date for such Spin-Off, but prior to or on the last Trading Day of the Valuation Period for such Spin-Off, such conversion reference period will
be suspended on the first such Trading Day and will 

  
 60 

 
not resume on the first Trading Day immediately following the end of such Valuation Period (and the settlement of such Note will be postponed accordingly). 

For purposes of the above calculation, (i) the “Closing Price” of any Capital Stock or similar equity interest shall be
calculated in a manner analogous to that used to calculate the Last Reported Sale Price of the Common Stock, (ii) whether a day is a “Trading Day” (and whether a day is a “Scheduled Trading Day” and whether a “Market
Disruption Event” has occurred) for the applicable Capital Stock or similar equity interest shall be determined in a manner analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and
whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period will be determined based on whether a day is a Trading Day for both the Common Stock and such
Capital Stock or similar equity interest. 
 For purposes of this Section 14.04(c) (and subject in all respect to
Section 14.11), rights, options or warrants distributed by the Company to all holders of 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 14.04(c) (and no adjustment to the Conversion Rate under this
Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate
shall be made under this Section 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such
rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend
Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the
event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a
distribution amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders
thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such
distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to 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. 

  
 61 

 For purposes of Section 14.04(a), Section 14.04(b) and this Section 14.04(c),
any dividend or distribution to which this Section 14.04(c) is applicable that also includes one or both of: 
 (A) a
dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable (the “Clause B Distribution”), 

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

 
 

 
 where, 
  

					
			
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR’	 	=	 	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	 	=	 	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	 	=	 	the amount in cash per share the Company distributes to all or substantially all holders of its Common Stock.

 Any increase pursuant to this Section 14.04(d) shall become effective immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the 

  
 62 

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

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

 
 where, 
  

					
			
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the 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;
			
	CR’	 	=	 	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the 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);
			
	OS’	 	=	 	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
			
	SP’	 	=	 	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date
such tender or exchange offer expires.

  
 63 

 The adjustment to the Conversion Rate under this Section 14.04(e) shall occur at the close of business
on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that 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 14.04(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) 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. 
 (g) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of
this Section 14.04, and to the extent permitted by applicable law and subject to the applicable rules of The NASDAQ Global Select Market, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20
Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of The NASDAQ Global Select Market, the
Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares (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. 
 (h) Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be adjusted: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the
investment of additional optional amounts in shares of Common Stock under any plan; 
 (ii) upon the issuance of
any shares of Common Stock, restricted stock or restricted stock units, options or rights (including stock appreciation 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; 

  
 64 

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

(vi) upon the repurchase of any shares of the Common Stock pursuant to an open-market share repurchase program or other
buy-back transaction that is not a tender offer or exchange offer of the nature described in Section 14.04(e)); 
 (vii) for the sale or issuance of new shares of the Common Stock or securities convertible into or exercisable for shares of the Common Stock for cash, including at a price per share less than the fair
market value thereof or otherwise, except as described in Section 14.04(a) through Section 14.04(e), or in an acquisition (other than as described in Section 15.02); or 

(viii) for a third-party tender offer. 
 (i) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share. 

(j) 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. 

(k) For purposes of this Section 14.04, 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. 
 Section 14.05. Adjustments of Prices. Whenever any provision of this Indenture
requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values, the Closing Prices, the Daily Settlement Amounts or any other price 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 or multiple adjustments 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, the Closing
Prices, the Daily Settlement Amounts or any other price are to be calculated. 

  
 65 

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

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision
or combination), 
 (ii) any consolidation, merger 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 or transferee, as the case may be, shall execute with
the Trustee a supplemental indenture permitted under Section 10.01(b) 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 the Conversion Obligation shall be calculated and settlement in accordance with Section 14.02 such that (A) the amount otherwise payable in cash upon conversion of the Notes as set forth under Section 14.02 shall continue to be
payable in cash, (B) the number of shares of Common Stock otherwise deliverable upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that
number of shares of Common Stock would have been entitled to receive in such Merger Event and (C) 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 

  
 66 

 
by the holders of Common Stock that affirmatively make such an election, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the
consideration referred to in clause (i) attributable to one share of Common Stock. If the holders receive only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (x) the
consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.03),
multiplied by the price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion
Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. 

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

(b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 14.07, the
Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such 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) None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash and shares of
Common Stock, if any, as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Merger Event. 
 (d) The above provisions of this Section shall similarly apply to successive Merger Events. 
 Section 14.08. Certain Covenants. (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable and free from all taxes, liens
and charges with respect to the issue thereof (other than taxes, liens and charges incurred by a Holder). 

  
 67 

 (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 quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated
quotation system, any Common Stock issuable upon conversion of the Notes. 
 Section 14.09. Responsibility of Trustee.
The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any
increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the
same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered
upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained
in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into
pursuant to Section 14.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to
any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in
relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be
responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the
notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to
the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). 
 Section 14.10. Notice to Holders Prior to Certain Actions. In case of any: 

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

  
 68 

 (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 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 14.11. Stockholder Rights Plans. To the extent that the Company has a rights plan in effect on any Trading Day of the
Observation Period applicable to any Note, a Holder may convert each share of Common Stock, if any, issued upon such conversion with respect to such Trading Day, shall be entitled to receive the appropriate number of rights, if any, with respect to
such shares of Common Stock and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended
from time to time. However, if, prior to such Trading Day, the rights have separated from the Common Stock, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the
Common Stock Distributed Property as provided in Section 14.04(c), and further adjusted in the event of certain events affecting such rights following any separation from the Common Stock and subject to readjustment in the event of the
expiration, termination or redemption of such rights. For purposes of calculating the per share fair market value of the Distributed Property, any shares of the Common Stock held by any Person who is ineligible to receive such distribution under the
terms of the rights plan shall not be deemed outstanding. Any distribution of rights or warrants pursuant to a rights plan that would allow a Holder to receive upon conversion, in addition to shares of Common Stock, the rights described therein with
respect to such shares of Common Stock (unless such rights or warrants have separated from the Common Stock) shall not constitute a distribution of rights or warrants that would entitle a Holder to an adjustment to the Conversion Rate. 

Section 14.12. Limit on Issuance of Shares of Common Stock Upon Conversion. Notwithstanding anything to the contrary in this
Indenture, if an event occurs that would result in an increase in the Conversion Rate by an amount in excess of limitations imposed by any shareholder approval rules or listing standards of any national or regional securities exchange that are
applicable to the Company, the Company will, at its option, either obtain stockholder approval of any issuance of Common Stock upon conversion of the Notes in excess such 

  
 69 

 
limitations or deliver cash in lieu of any shares of Common Stock otherwise deliverable upon conversions in excess of such limitations based on the Daily VWAP on each Trading Day of the relevant
Observation Period in respect of which, in lieu of delivering shares of Common Stock, the Company delivers cash pursuant to this Section 14.12. 
 ARTICLE 15 
 REPURCHASE OF NOTES
AT OPTION OF HOLDERS 
 Section 15.01. Repurchase at Option of
Holders. 
 (a) Each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for
cash on each of May 5, 2017, May 1, 2022 and May 1, 2027 (each, a “Repurchase Date”), all of such Holder’s Notes, or any portion thereof that is an integral multiple of $1,000 principal amount, at a
repurchase price (the “Repurchase Price”) that is equal to 100% of the principal amount of the Notes to be repurchased, together with accrued and unpaid interest to, but excluding, such Repurchase Date; provided that any such
accrued and unpaid interest (other than accrued and unpaid interest with respect to the Repurchase Date on May 5, 2017) shall be paid not to the Holders submitting the Notes for repurchase on the relevant Repurchase Date but instead to the
Holders of such Notes at the close of business on the Regular Record Date immediately preceding such Repurchase Date. Not later than 20 Business Days prior to each Repurchase Date, the Company shall mail a notice (the “Company
Notice”) by first class mail to the Trustee, to the Paying Agent and to each Holder at its address shown in the Note Register of the Note Registrar (and to beneficial owners as required by applicable law). The Company Notice shall include a
form of Repurchase Notice to be completed by a holder and shall state: 
 (i) the last date on which a Holder may
exercise its repurchase right pursuant to this Section 15.01 (the “Repurchase Expiration Time”); 
 (ii) the Repurchase Price; 
 (iii) the name and address of the
Conversion Agent and Paying Agent; 
 (iv) that the Notes with respect to which a Repurchase Notice has been
delivered by a Holder may be converted only if the Holder withdraws the Repurchase Notice in accordance with the terms of this Indenture; 
 (v) that the Holder shall have the right to withdraw any Notes surrendered prior to the Repurchase Expiration Time; and 

(vi) the procedures a Holder must follow to exercise its repurchase rights under this Section 15.01 and a brief

Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. 

  
 70 

 Simultaneously with providing the Company Notice, the Company shall publish a notice
containing the information included in the 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. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase
rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.01. 

Repurchases of Notes under this Section 15.01 shall be made, at the option of the Holder thereof, upon: 

(A) delivery to the Paying Agent by the Holder of a duly completed notice (the “Repurchase Notice”) in
the form set forth in Attachment 3 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 during the period beginning at any time from the opening of business on the date that is 20 Business Days prior to the Repurchase Date until the close of business on the Repurchase Date; and 

(B) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the
Repurchase Notice (together with all necessary endorsements) 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 Repurchase Price therefor. 
 Each Repurchase Notice shall
state: 
 (A) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

 (B) the portion of the principal amount of the Notes to be repurchased, which must be in multiples of $1,000
and 
 (C) 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 Repurchase Notice must comply with appropriate
Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Repurchase Notice contemplated by this Section 15.01 shall have the right to withdraw, in whole or in part, such Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Repurchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03. 

  
 71 

 The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase
Notice or written notice of withdrawal thereof. 
 No Repurchase Notice with respect to any Notes may be surrendered by a Holder
thereof if such Holder has also surrendered a Fundamental Change Repurchase Notice and not validly withdrawn such Repurchase Notice in accordance with Section 15.03. 
 (b) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the Holders on any Repurchase Date if the principal amount of the Notes has been accelerated, and such
acceleration has not been rescinded, on or prior to such Repurchase Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Repurchase Price with respect to such Notes). 

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time,
each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the
“Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of
the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls
after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular
Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15. 
 (b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon: 
 (i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached
hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case 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: 

  
 72 

 (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 in multiples of $1,000; and 
 (iii) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental
Change Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the
close of business on the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 

(c) On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to
all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change
and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the
applicable procedures of the Depositary. 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;

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

(iv) the Fundamental Change Repurchase Price;

Conversion Rate; 
 (viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been
delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; 
 (ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes
pursuant to this Section 15.02. 
 At the Company’s request, the Trustee shall give such notice in the Company’s
name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental
Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a
Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been
cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
 Section 15.03. Withdrawal of Repurchase Notice or Fundamental Change Repurchase Notice. (a) A Repurchase Notice or Fundamental Change Repurchase Notice may be withdrawn with respect to all or
a portion of the Notes to which such Repurchase Notice or Fundamental Change Repurchase Notice relates by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 15.03
at any time prior to the close of business on the Repurchase Date or prior to the close of business on the Fundamental Change Repurchase Date, as the case may be, specifying: 

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, which must be in
multiples of $1,000, 
 (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 

  
 74 

 (iii) the principal amount, if any, of such Note that remains subject to the
original Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, which portion must be in multiples of $1,000; 

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

If a Repurchase Notice or Fundamental Change Repurchase Notice is given and withdrawn within the period beginning at any time from the
opening of business on the date that is 20 Business Days prior to the Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, until the close of business on the Repurchase Date or the Fundamental Change Repurchase Date, as the
case may be, the Company will not be obligated to repurchase the Notes or the portion of Notes listed in the notice of withdrawal. 
 Section 15.04. Deposit of Repurchase Price or 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 Business Day following the Repurchase Date or Fundamental Change Repurchase
Date, as the case may be, an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Repurchase Price or 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 Fundamental Change Repurchase Date) will be made on the later of (i) the Business Day following the
Repurchase Date or Fundamental Change Repurchase Date, as the case may be, (provided the Holder has satisfied the conditions in Section 15.01 or Section 15.02, as the case may be) and (ii) the time of book-entry transfer or the
delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 15.01 or Section 15.02, as applicable, by mailing checks for the amount payable to the Holders of
such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.
The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Repurchase Price or Fundamental Change Repurchase Price, as the case may be. 

(b) Payment of the Repurchase Price or Fundamental Change Repurchase Price, as the case may be, for a Note for which a Repurchase Notice
or a Fundamental Change Repurchase Notice, as applicable, has been delivered and not withdrawn is conditioned upon book-entry transfer or delivery of the Note (together with all necessary endorsements) to the Trustee (or other Paying Agent appointed
by the Company). If by 11:00 a.m. New York City time, on the Business Day following the Repurchase Date or Fundamental Change Repurchase Date, as the case may be, the Trustee (or other Paying Agent appointed by the Company) holds money or securities
sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Repurchase Date or Fundamental Change Repurchase Date, as the case may be, then, with respect to the Notes that have been properly surrendered for
repurchase and not validly withdrawn, whether or not book-entry transfer of such Notes has been made or such Notes have been delivered to the Trustee or Paying Agent, (i) such Notes will cease to be

  
 75 

 
outstanding, (ii) interest will cease to accrue on such Notes and (iii) all other rights of the Holders of such Notes will terminate, other than the right to receive the Repurchase
Price or Fundamental Change Repurchase Price as the case may be upon delivery of such Note. 
 (c) Upon surrender of a Note that
is to be repurchased in part pursuant to Section 15.01 or Section 15.02, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the
unrepurchased portion of the Note surrendered. 
 Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of
Notes. In connection with any repurchase offer, the Company will, if required: 
 (a) comply with the provisions of Rule
13e-4 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 15 to be exercised in the time and in
the manner specified in this Article 15. 
 ARTICLE 16 
 OPTIONAL REDEMPTION 
 Section 16.01. Optional
Redemption. No sinking fund is provided for the Notes. The Notes shall not be redeemable by the Company prior to May 5, 2017. On or after May 5, 2017, and prior to the Maturity Date, the Company may redeem (an “Optional
Redemption”) for cash all or part of the Notes, at the Redemption Price. 
 Section 16.02. 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 16.01, it shall fix a date for redemption (each, a
“Redemption Date”) and it or, at its written request received by the Trustee not less than 55 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 40 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. The Redemption Date must be a Business Day. 
 (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

  
 76 

 
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; 
 (ii) the Redemption Price; 

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and
that interest thereon, if any, shall cease to accrue on and after the Redemption 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 third Scheduled Trading Day immediately preceding the Redemption Date; 
 (vi) the procedures a converting Holder must follow to convert its Notes; 
 (vii) the Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with Section 14.03; 

(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 such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 
 A Redemption Notice shall be irrevocable. 
 (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. 
 Section 16.03. Payment of Notes Called for Redemption.
(a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 16.02, 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 

  
 77 

 
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 16.03. 
 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 16.04. 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).

Indenture specifically provides that the Trustee shall or may receive an Opinion of Counsel in connection with any action to be taken by the Trustee or the Company hereunder, the Trustee shall be entitled to, or entitled to request, such Opinion of
Counsel. 
 Section 17.06. Legal Holidays. In any case where any Interest Payment Date, Fundamental Change Repurchase
Date, Conversion Date, Repurchase Date or Maturity Date is not a Business Day, then any action to be taken on such date need not be taken on such date, but may be taken on the next succeeding Business Day with the same force and effect as if taken
on such date, and no interest shall accrue in respect of the delay. 
 Section 17.07. No Security Interest Created.
Nothing in this Indenture or in the Notes, expressed or implied, shall be construed to constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any jurisdiction.

 Section 17.08. Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or implied, shall give to
any Person, other than the Holders, the parties hereto, any Paying Agent, any Conversion Agent, any authenticating agent, any Note Registrar and their successors hereunder, any benefit or any legal or equitable right, remedy or claim under this
Indenture. 
 Section 17.09. Table of Contents, Headings, Etc. The table of contents and the titles and headings of the
articles and sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof. 

Section 17.10. Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its behalf
and subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Section 2.04, Section 2.05, Section 2.06,
Section 2.07, Section 10.04 and Section 15.04 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to authenticate and deliver

  
 80 

 
Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the
Trustee” and a certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such
authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant to Section 7.08. 
 Any
corporation or other entity into which any authenticating agent may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating
agent shall be a party, or any corporation or other entity succeeding to the corporate trust business of any authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is
otherwise eligible under this Section 17.10, without the execution or filing of any paper or any further act on the part of the parties hereto or the authenticating agent or such successor corporation or other entity. 

Any authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee
may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time
any authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice of such appointment to the Company and shall mail notice of such
appointment to all Holders as the names and addresses of such Holders appear on the Note Register. 
 The Company agrees to pay
to the authenticating agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 

The provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and this Section 17.10 shall be
applicable to any authenticating agent. 
 If an authenticating agent is appointed pursuant to this Section 17.10, the
Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
                                  
                           , 
 as Authenticating Agent, certifies that this is one of the Notes described 
 in the within-named
Indenture.

 Section 17.11. Execution in Counterparts. This Indenture may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one
and the same instrument. 

  
 81 

 Section 17.12. Severability. In the event any provision of this Indenture or in the
Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired. 

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

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

Section 17.16. U.S.A. Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot
Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a
relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

 [FORM OF REVERSE OF NOTE] 

TIBCO Software Inc. 
 2.25% Convertible Senior Note due 2032 
 This Note is one of a duly authorized
issue of Notes of the Company, designated as its 2.25% Convertible Senior Notes due 2032 (the “Notes”), limited to the aggregate principal amount of $600,000,000 all issued or to be issued under and pursuant to an Indenture dated as
of April 23, 2012 (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 a Paying Agent to
collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

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

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on, and the consideration
due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money 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 

  
 A-6

 
to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized
denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder
of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 
 The Notes 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 Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash and shares of Common Stock, if any, 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.
