legend set forth in this Section 2.04(a) (together with any Common Stock issued upon conversion of the Notes and required to bear the legend set forth in Section 2.04(b), collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.04(a) (including those contained in the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise
waived by written consent of the Company with written notice to the Trustee and the Paying Agent as provided below. 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 2.04(a) and Section 2.04(b), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 

Until the Resale Restriction Termination Date, 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 2.04(b), if applicable) shall bear a legend in substantially the following form (unless such Notes
have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from registration
provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee and the Paying Agent): 

THIS NOTE AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS NOTE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED PRIOR TO THE RESALE RESTRICTION TERMINATION DATE EXCEPT: 

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

  
 18 








 (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF
ANY TRANSFER IN ACCORDANCE WITH CLAUSE (D) ABOVE, THE COMPANY, THE TRUSTEE, AND THE PAYING AGENT RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO
DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT. 
 THE “RESALE RESTRICTION TERMINATION DATE” MEANS THE LATER OF: (A) THE DATE THAT IS ONE YEAR AFTER THE LAST
ORIGINAL ISSUANCE DATE OF THE NOTES OR SUCH SHORTER PERIOD OF TIME PERMITTED BY RULE 144 OR ANY SUCCESSOR PROVISION THERETO; AND (B) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW. 

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on
the Form of Assignment and Transfer has been checked. 
 Any Note (or security issued in exchange or substitution therefor) 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 2.04(a), 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 2.04(a) and shall not be assigned a restricted CUSIP number. No later than the fifth day immediately following the Free
Trade Date, the Company shall cause every beneficial interest in any Note represented by a Global Note that bears the restricted legend specified in this Section 2.04(a) to be automatically exchanged for beneficial interests in a Global Note
that shall not bear such restrictive legend and shall not be assigned a restricted CUSIP number. To effect such exchange, the Company (A) will deliver to the Depositary an instruction letter for the Depositary’s mandatory exchange process
at least 15 days immediately prior to the Free Trade Date and (B) will deliver to each of the Trustee and the Note Registrar a duly completed free transferability certificate in the form set forth on Exhibit E (the “Free Transferability
Certificate”) promptly upon the occurrence of the Free Trade Date. Upon receipt of the Free Transferability Certificate by the Trustee and the Note Registrar, the legend set forth above shall be deemed removed from each Global Note
specified in the Free Transferability Certificate and the restricted CUSIP number shall be deemed removed from each such Global Note and deemed replaced with an unrestricted CUSIP number, with no further action required by the Company, the Trustee,
the Note Registrar, or, if applicable, the Depositary. Prior 

  
 19 








 
to the Company’s delivery of the Free Transferability Certificate and afterwards, the Company, the Trustee, and the Note Registrar will comply with the rules and procedures of the Depositary
and otherwise use reasonable efforts to cause each Global Note to be identified by an unrestricted CUSIP number in the facilities of the Depositary by the Free Trade Date or as promptly as possible thereafter. In addition, on the Free Trade Date or
promptly thereafter, the Company, or the Trustee upon written instruction by the Company, will provide Bloomberg L.P. with a copy of the Free Transferability Certificate and will use reasonable efforts to cause Bloomberg L.P. to adjust its screen
page for the Notes to indicate that the Notes are no longer Restricted Securities and are now identified by an unrestricted CUSIP number. Notwithstanding anything to the contrary in this paragraph, the Company will not be required to deliver or
provide the Free Transferability Certificate if it reasonably believes that removal of the restrictive legend or the changes to the CUSIP number for the Notes could result in or facilitate transfers of the Notes in violation of applicable law;
provided that, this sentence does not limit the application of Section 9.10. 
 The Company shall promptly notify the Trustee,
the Agent, and the Holders in writing 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. 

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

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE
OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED PRIOR TO THE RESALE RESTRICTION TERMINATION DATE EXCEPT: 
 (A) TO THE
COMPANY OR ANY SUBSIDIARY THEREOF, OR 
 (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE
SECURITIES ACT, OR 
 (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

  
 20 








 (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF
ANY TRANSFER IN ACCORDANCE WITH CLAUSE (D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE
REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT. 
 THE “RESALE RESTRICTION TERMINATION DATE” MEANS THE LATER OF: (A) THE DATE THAT IS
ONE YEAR AFTER THE LAST ORIGINAL ISSUANCE DATE OF THE COMPANY’S 4.50% SENIOR SUBORDINATED CONVERTIBLE NOTES DUE 2018 OR SUCH SHORTER PERIOD OF TIME PERMITTED BY RULE 144 OR ANY SUCCESSOR PROVISION THERETO; AND (B) SUCH LATER DATE, IF ANY,
AS MAY BE REQUIRED BY APPLICABLE LAW.  
 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 transfer agent for the Common Stock, be exchanged for a new certificate or
certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.04(b).  

(c) The Company shall not, and shall not permit any of the “affiliates” (as defined in Rule 144) it controls to,
resell any of the Notes that constitute “restricted securities” under Rule 144 that have been reacquired by any of them.  

SECTION 2.05. Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the
Company by the manual or facsimile signature of its Chief Executive Officer, President, Treasurer, Secretary or any of its Vice Presidents. 

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to
the Authenticating Agent for authentication, together with a Company Order for the authentication and delivery of such Notes, which order shall set forth the number of separate Note certificates, the principal amount of each of the Notes to be
authenticated, the date on which the original issuance of Notes is to be authenticated, the registered holders of the said Notes and delivery instructions, and the Authenticating Agent in accordance with such Company Order shall authenticate and
deliver such Notes. 

  
 21 








 Only such Notes as shall bear thereon a certificate of authentication substantially in the form
set forth on the form of Note attached as Exhibit A hereto, executed manually by an authorized signatory of the Authenticating Agent, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by
the Authenticating Agent upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture. 

In case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall have
been authenticated and delivered by the Authenticating Agent, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of
the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such
person was not such an officer. 
 SECTION 2.06. Exchange and Registration of Transfer of Notes; Depositary. (a) The
Company shall cause to be kept at the Corporate Trust Office of the Agent a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 9.02 being herein
sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such
register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Company initially appoints Citibank, N.A. as “Note Registrar” for the purpose of
registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-registrars in accordance with Section 9.02. 

Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements
for such transfer set forth in this Section 2.06, the Company shall execute, and the Authenticating Agent shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized
denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. 

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the
Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 9.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Authenticating Agent shall authenticate and
deliver, the Notes that the holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 

  
 22 








 All Notes presented or surrendered for registration of transfer or for exchange, repurchase or
conversion shall (if so required by the Company, the Transfer Agent, the Paying Agent, the Conversion Agent, the Note Registrar or any co-registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company and duly executed by the holder thereof or its attorney-in-fact duly authorized in writing. 
 No service charge
shall be charged to the Noteholder for any exchange or registration of transfer of Notes, but the Company, the Agent, or the Trustee may require payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be
imposed in connection therewith as a result of the name of the holder of the new Notes issued upon such exchange or registration of transfer of Notes being different from the name of the holder of the old Notes presented or surrendered for such
exchange or registration of transfer. 
 None of the Company, the Trustee, the Agent, the Note Registrar or any co-registrar shall be
required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or a portion of any
Note, surrendered for repurchase (and not withdrawn) in accordance with Article 3 hereof. 
 All Notes issued upon any
registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such
registration of transfer or exchange. 
 (b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless
otherwise required by law, all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial
interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Transfer Agent, the Paying Agent, the Trustee or the Custodian) in accordance with this Indenture and the
procedures of the Depositary therefor. 
 (c) Members of, or participants in, the Depositary (“Agent
Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary or under the Global Note, and the Depositary (including, for this purpose, its nominee) may be treated by the
Company, the Transfer Agent, the Paying Agent, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. 

(d) Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.04(a)), 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 


  
 23 








 
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 and the Agent by or on behalf of the Depositary in accordance with customary procedures of the
Depositary and in compliance with this Section 2.04(a). 
 The Depositary shall be a clearing agency registered under
the Exchange Act. The Company initially appoints The Depository Trust Company (“DTC”) 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 Paying Agent as custodian for Cede & Co. Neither the Trustee, the Agent nor any agent thereof shall have any responsibility or liability for any actions taken or
not taken by the Depositary. 
 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 Authenticating Agent, 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 to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the
related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Paying Agent such Global Notes
shall be canceled. 
 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this
Section 2.06(d) 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 Note Registrar. Upon execution
and authentication, the Agent 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 Paying Agent in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for
Physical Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in
accordance with standing procedures and existing instructions between the Depositary and the Custodian, be appropriately reduced 

  
 24 








 
or increased, as the case may be, and an endorsement shall be made on the Schedule of Exchanges of such Global Note, by the Transfer Agent or the Custodian, at the direction of the Paying Agent,
to reflect such reduction or increase. 
 None of the Company, the Agent, the Trustee nor any agent of the Company, the Agent, or the
Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. 
 SECTION 2.07. 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 Authenticating Agent shall authenticate and deliver, a new Note, bearing a 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 and the 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 Agent
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 Authenticating Agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the
Trustee, the Agent, and the Company may require. Upon the issuance of any substitute Note, the Company or the Agent may require the payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be
imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been tendered for repurchase upon a Fundamental Change or in connection with an optional redemption or is about to
be converted into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, 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,
the Transfer Agent, the Paying Agent, the Conversion Agent, 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, including without limitation if a Note is replaced and subsequently presented or claimed for payment and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Transfer Agent, 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. 

  
 25 








 Every substitute Note issued pursuant to the provisions of this Section 2.07 by
virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the
benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express
condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any
law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 

SECTION 2.08. Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and the
Authenticating Agent 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 Notes in
certificated form 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
Authenticating Agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay the Company will execute and deliver to the Authenticating Agent Notes in
certificated form (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 9.02 and the Authenticating Agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. 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 Notes in certificated form authenticated and
delivered hereunder. 
 SECTION 2.09. Cancellation of Notes Paid, Etc. All Notes surrendered for the purpose of
payment, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the Paying Agent and promptly canceled by it, and no
Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Paying Agent shall dispose of canceled Notes in accordance with its customary procedures. If the Company shall acquire any of the
Notes, such acquisition shall not operate as satisfaction of the Indebtedness represented by such Notes unless and until the same are delivered to the Paying Agent for cancellation. 

SECTION 2.10. CUSIP Numbers. In issuing the Notes, the Company may use “CUSIP” numbers (if then
generally in use), and, if so, the Trustee and/or any Agent shall use “CUSIP” numbers in notices issued to Holders of the Notes as a convenience to them; 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  

  
 26 








 
notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company will promptly notify the Trustee and all Agents in writing of any change in the
“CUSIP” numbers. 
 SECTION 2.11. Repurchases. The Company may from time to time repurchase the Notes in open market
purchases or otherwise without prior notice to Holders of Notes. Any Notes repurchased by the Company will be immediately retired and not be outstanding for any purpose under this Indenture. 

ARTICLE 3 
 FUNDAMENTAL
CHANGES AND PURCHASES THEREUPON 
 SECTION 3.01. Purchase at Option of Holders Upon a Fundamental Change.
(a) Generally. If a Fundamental Change occurs at any time prior to October 15, 2018, then each Holder of Notes shall have the right, at such Holder’s option, to require the Company to purchase for cash any or
all of such Holder’s Notes, or any portion of the principal amount thereof, that is equal to $1,000 or a multiple of $1,000, on a date specified by the Company that is no earlier than the 20th calendar day following the date of, and no later
than the 35th calendar day following the date of, delivery of the Fundamental Change Company Notice (as defined below) (the “Fundamental Change Purchase Date”), at a purchase price equal to 100% of the principal amount
thereof, together with accrued and unpaid interest thereon to, but excluding, the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”); provided, however, that if a Fundamental Change
Purchase Date is after a Regular Record Date and on or prior to the Interest Payment Date to which such Regular Record Date relates, the interest payable in respect of such Interest Payment Date shall be payable to the Holders of record as of the
corresponding Regular Record Date and the Fundamental Change Purchase Price shall be equal to 100% of the principal amount of the Notes to be purchased pursuant to this Article 3. Any Notes purchased by the Company will be paid
for in cash. The requirement for the Company to purchase any Notes on the Fundamental Change Purchase Date will be subject to extension to comply with applicable law. 

Purchases of Notes under this Section 3.01 shall be made, at the option of the Holder thereof, upon: 

(i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Purchase
Notice”) in the form set forth on the reverse of the Note as Exhibit C thereto, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for tendering interests in Global Notes, if the Notes are not Physical
Notes, in each case prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date; and 

(ii) delivery of the Notes, in the case of Physical Notes, to the Paying Agent appointed by the Company (together with all
necessary endorsements for transfer), or book-entry transfer of the Notes, in compliance with the procedures of the Depositary, such delivery or transfer being a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor;


  
 27 








 provided, however, that the Company shall have no obligation to deliver a
Fundamental Change Company Notice or to purchase Notes pursuant to this Article 3 if: 
 (A) a third party delivers such
notice and makes a fundamental change purchase offer (a “Fundamental Change Purchase Offer”) in the manner, at the times and otherwise in compliance with the requirements set forth in this Article 3 applicable to a
Fundamental Change Purchase Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the fundamental change purchase offer; 

(B) prior to or simultaneously with the Fundamental Change a Redemption Notice has been given pursuant to
Article 15 hereof (unless and until there is a default in the payment of the applicable Redemption Price); or 

(C) if the Company’s obligations under this Indenture are discharged as described under Section 13.01 hereof
on or promptly following the Fundamental Change. 
 The Fundamental Change Purchase Notice in respect of any Notes to be purchased shall
state: 
 (i) if such Notes are Physical Notes, the certificate numbers of such Notes, or if such Notes are in global form,
the Fundamental Change Purchase Notice must also comply with appropriate procedures of the Depositary; 
 (ii) the portion of
the principal amount of such Notes, which must be $1,000 or a multiple thereof; and 
 (iii) that such Notes are to be
purchased by the Company pursuant to the applicable provisions of the Notes and this Indenture. 
 A Fundamental Change Purchase Offer may
be made in advance of a Fundamental Change and may be conditional upon the occurrence of a Fundamental Change if a definitive agreement is in place for the Fundamental Change at the time the Fundamental Change Purchase Offer is made. 

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice
contemplated by this Section 3.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change
Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.03 below. 

  
 28 








 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change
Purchase Notice or written notice of withdrawal thereof. 
 (b) Fundamental Change Company Notice. On or before
the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the Notes, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a notice (the “Fundamental
Change Company Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or, in the case of any Global Notes, in
accordance with the procedures of the Depositary for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall issue a press release or publish a notice containing the information included therein or
shall publish such information on the Company’s website or through such other public medium as the Company may use at such time. 

Each Fundamental Change Company Notice shall specify: 

(i) the events causing a Fundamental Change; 

(ii) the date of the Fundamental Change; 

(iii) the last date on which a Holder of Notes may exercise the repurchase right pursuant to this Article 3; 

(iv) the Fundamental Change Purchase Price; 

(v) the Fundamental Change Purchase Date; 

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

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

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

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the purchase rights of the Holders of Notes
or affect the validity of the proceedings for the purchase of the Notes pursuant to this Section 3.01. 

  
 29 








 (c) No Payment During Events of Default. There shall be no purchase of any Notes
pursuant to this Section 3.01 if there has occurred and is continuing an Event of Default with respect to the Notes (other than an Event of Default that is cured by the payment of the Fundamental Change Purchase Price of the Notes). The
Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the continuance of an Event of Default (other than an Event of Default that is cured by the payment of the Fundamental Change Purchase Price
with respect to the Notes) and shall deem canceled any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary, in which case, upon such return and cancellation, the Fundamental Change Purchase Notice
with respect thereto shall be deemed to have been withdrawn. 
 SECTION 3.02. Effect of Fundamental Change Purchase Notice.
Upon receipt by the Paying Agent of the Fundamental Change Purchase Notice specified in Section 3.01 hereof, the Holder of the Note in respect of which such Fundamental Change Purchase Notice was given shall (unless
such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.03 hereof) thereafter be entitled to receive solely the Fundamental Change Purchase Price in cash with respect to such Note. Such Fundamental
Change Purchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of (x) the Fundamental Change Purchase Date with respect to such Note (provided the conditions in
Section 3.01 hereof have been satisfied) and (y) the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.01
hereof. 
 SECTION 3.03. Withdrawal of Fundamental Change Purchase Notice. A Fundamental Change Purchase Notice may be
withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the close of business on the date that is at least two Business
Days prior to the Fundamental Change Purchase Date, specifying: 
 (i) the principal amount of the Notes with respect
to which such notice of withdrawal is being submitted; 
 (ii) if Physical Notes have been issued, the certificate numbers of
the withdrawn Notes, or if Physical Notes have not been issued, the notice must comply with appropriate procedures of the Depositary; and 

(iii) the principal amount, if any, of such Notes that remains subject to the original Fundamental Change Purchase Notice,
which portion must be in principal amounts of $1,000 or a multiple of $1,000. 
 The Paying Agent will promptly return to the
respective Holders thereof any Physical Notes with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.03. 

SECTION 3.04. Deposit of Fundamental Change Purchase Price. Prior to 11:00 a.m. (local time in The City of New York) on the date
that is at least one Business Day prior to the date on the Fundamental Change Purchase Date, the Company  

  
 30 








 
shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein)
an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Notes or portions thereof that are to be purchased as of the Fundamental Change Purchase Date;
provided, however, that to the extent any such funds are received by the Paying Agent from the Company after 11:00 a.m. (local time in The City of New York) on such date, such funds will be deemed to have been deposited within one
Business Day of the receipt thereof. If the Paying Agent holds cash sufficient to pay the Fundamental Change Purchase Price of the Notes for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this
Indenture on the Fundamental Change Purchase Date, then as of such Fundamental Change Purchase Date, (a) such Notes will cease to be outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of such Notes is made
or such Notes have been delivered to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest
upon delivery or book-entry transfer of such Notes). 
 SECTION 3.05. Notes Purchased in Whole or in Part. Any Note
that is to be purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Notes, due endorsement by, or a written instrument of transfer in
form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Authenticating Agent shall authenticate and deliver to the Holder
of such Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is
not purchased. 
 SECTION 3.06. Covenant to Comply With Applicable Laws Upon Purchase of Notes. In connection with any
offer to purchase Notes under Section 3.01 hereof, the Company shall, in each case if required, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be
applicable, (ii) file a Schedule TO or any other required schedule under the Exchange Act and (iii) otherwise comply with all federal and state securities laws so as to permit the rights and obligations under
Section 3.01 to be exercised in the time and in the manner specified in Section 3.01, and shall not be deemed to have breached its obligations under the Indenture by virtue of its compliance with
such securities laws or regulations. 
 SECTION 3.07. Repayment to the Company. To the extent that the aggregate amount
of cash deposited by the Company pursuant to Section 3.04 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof that the Company is obligated to purchase as of the Fundamental Change
Purchase Date, then, following the Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company.

 ARTICLE 4  

CONVERSION 

SECTION 4.01. Right to Convert. (a) Subject to and upon compliance with the provisions of this Indenture, each Holder of
Notes shall have the right, at such Holder’s option, to convert the principal amount of any such Notes, or any portion of such principal amount equal to $1,000 or a multiple of $1,000 thereof, at the Conversion Rate in effect on the Conversion
Date for such Notes, (x) prior to April 15, 2018, only upon satisfaction of one or more of the conditions described in clauses (i) through (v) below and (y) on or after April 15, 2018, at any time prior to the close of
business on the second Scheduled Trading Day immediately preceding October 15, 2018 irrespective of the conditions described in clauses (i) through (v) below: 

(i) Prior to April 15, 2018, a Holder of Notes may surrender all or a portion of its Notes for conversion during any
fiscal quarter (and only during such fiscal quarter) commencing after October 31, 2013, 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 applicable Conversion Price in effect on each applicable Trading Day. The Company shall notify the Trustee and the Conversion
Agent if the Notes become convertible in accordance with this Section 4.01 (a)(i). 
 (ii) Prior to
April 15, 2018, a Holder of Notes may surrender its Notes for conversion during the five Business Day period 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 the procedures set forth in this Section 4.01(a)(ii), for each Trading Day of such period was less than 98% of the product of the Last
Reported Sale Price of the Common Stock and the Conversion Rate on such Conversion Date (the “Trading Price Condition”). The Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Notes in accordance
with this Section 4.01(a)(ii) unless requested by the Company, and the Company shall have no obligation to make such request unless a Holder of Notes provides the Company with reasonable evidence that the Trading Price per $1,000
principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. The Company shall instruct the Bid Solicitation Agent to determine (or, if the Company is then
acting as Bid Solicitation Agent, the Company shall determine) the Trading Price of the Notes beginning on the next Trading Day promptly following the receipt of such evidence and on each successive Trading Day until such Trading Day on which 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. If the Company does not so instruct the Bid Solicitation Agent
to obtain (or, if the Company is then acting as Bid Solicitation Agent, the Company does not obtain) bids when required, the Trading Price per 

  
 32 








 
$1,000 principal amount of the Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate on each day the
Company fails to do so. If the Trading Price Condition has been met, the Company shall so notify Holders, the Trustee and the Conversion Agent. If, at any time after the Trading Price Condition has been met, the Trading Price per $1,000 principal
amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify Holders, the Trustee and the Conversion Agent. 

(iii) If the Company elects to: 

(A) issue to all or substantially all holders of Common Stock rights or warrants entitling them for a period of not more than
45 calendar days after the date of such issuance to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale Prices of a share of Common Stock for the 10 consecutive Trading Day period ending on the Trading
Day immediately preceding the date of announcement of such issuance; or 
 (B) distribute to all or substantially all holders
of Common Stock 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 each case, the Company shall notify the Holders of the Notes at
least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender Notes for conversion at any time until the earlier of the close of business on the
Business Day immediately prior to such Ex-Dividend Date or the Company’s announcement that such issuance or distribution will not take place, even if the Notes are not otherwise convertible at such time. 

(iv) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs, regardless of
whether a Holder has the right to require the Company to purchase the Notes pursuant to Article 3 hereof, or if the Company is a party to a consolidation, merger, binding share exchange, or sale, transfer or lease of all or substantially all
of the Company’s assets, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, Holders may surrender Notes for conversion at any time from or after the date which is 45 Scheduled Trading Days
prior to the anticipated effective date of such transaction until 35 Trading Days after the actual effective date of such transaction (or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Purchase
Date). The Company shall notify Holders, the Conversion Agent and the Trustee as promptly as 

  
 33 








 
practicable following the date the Company publicly announces such transaction, but in no event less than 45 Scheduled Trading Days prior to the anticipated effective date of such transaction.

 (v) If, at any time after October 15, 2016, the Company calls any or all of the Notes for redemption as described
under Article 15 hereof, Holders of the Notes will have the right to convert their Notes at any time until the close of business on the Business Day immediately preceding the Redemption Date, after which time Holders will no longer have the
right to convert their Notes on account of the Company’s delivery of notice of such redemption, unless the Company defaults in the payment of the Redemption Price. If a Holder elects to convert its Notes in connection with a Redemption Notice
issued by the Company, the Company shall: 
 (A) increase the conversion rate for the Notes as described under
Section 4.06 hereof; and 
 (B) pay to such Holder an amount equal to accrued and unpaid interest (including
additional amounts, if any) on the Notes that are surrendered for conversion to, but excluding, the conversion date; provided that if such conversion date occurs after a record date and on or prior to the corresponding Interest Payment Date,
the Company shall pay the interest due (including Additional Interest, if any) on that Interest Payment Date to the Holder of record on the relevant record date and no additional payment will be made pursuant to this clause. 

Failure by the Company to give any notice required by Section 4.01, or any defect therein, shall not affect the legality or
validity of the relevant transaction or event. 
 (b) Notes may not be converted after the close of business on the second Scheduled Trading
Day immediately preceding October 15, 2018. 
 SECTION 4.02. Conversion Procedures. (a) Each Note shall be
convertible at the office of the Conversion Agent and, if applicable, in accordance with the procedures of the Depositary. 

(b) In order to exercise the conversion privilege with respect to any interest in a Global Note, the Holder must comply with the
Depositary’s procedures for converting an interest in a Global Note and, if required, pay the funds required by Section 4.03(e) and pay any taxes or duties if required pursuant to Section 4.08, and the Conversion Agent
must be informed of the conversion in accordance with the customary practice of the Depositary. In order to exercise the conversion privilege with respect to any Physical Notes, the Holder of any such Notes to be converted, in whole or in part,
shall: 
 (i) complete and manually sign the conversion notice provided on the back of the Note (the
“Conversion Notice”) or a facsimile of the Conversion Notice; 

  
 34 








 (ii) deliver the Conversion Notice, which is irrevocable, and the Note to the
Conversion Agent; 
 (iii) if required, furnish appropriate endorsements and transfer documents, 

(iv) make any payment required under Section 4.03(e); and 

(v) if required, pay all transfer or similar taxes as set forth in Section 4.08. 

The date on which the Holder satisfies all of the applicable requirements set forth above is the “Conversion Date.”
The Conversion Agent will, as promptly as possible, and in any event within two Business Days of the receipt thereof, provide the Company and the Trustee with notice of any conversion by a Holder of the Notes. 

(c) Each Conversion Notice shall state the name or names (with address or addresses) in which any certificate or certificates for shares of
Common Stock which shall be issuable on such conversion shall be issued. All such Notes surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the registration of such Notes, be duly endorsed
by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or his duly authorized attorney. 

(d) In case any Notes of a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the
Authenticating Agent shall authenticate and deliver to the Holder of the Notes so surrendered, without charge, new Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Notes. 

(e) Each conversion shall be deemed to have been effected as to any Notes (or portion thereof) surrendered for conversion on the relevant
Conversion Date, and with respect to any shares of Common Stock that are issuable upon such conversion: (i) if such conversion was subject to a Physical Settlement, the Person in whose name the certificate or certificates for such shares of
Common Stock will be registered, shall become the holder of record of such shares as of the close of business on the Conversion Date; and (ii) if such conversion was subject to a Combination Settlement, the Person in whose name the certificate
or certificates for such shares of Common Stock will be registered, shall become the holder of record of such shares as of the close of business on the last Trading Day of the related Observation Period. 

(f) Upon the conversion of an interest in Global Notes, the Conversion Agent (or other Conversion Agent appointed by the Company) shall make a
notation on such Global Notes as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes effected through any Conversion Agent other than the Trustee. 

(g) Notwithstanding the foregoing, a Note in respect of which a Holder has delivered a Fundamental Change Purchase Notice exercising
such Holder’s option to require the Company to purchase such Note may be converted only if such notice of exercise is withdrawn in accordance with Article 3 hereof prior to the close of business on the Business Day prior to the relevant
Fundamental Change Purchase Date. 

  
 35 








 SECTION 4.03. Settlement Upon Conversion. (a) Except as provided in
Section 4.06(b), upon any conversion of any Note, the Company shall deliver to converting Holders, in respect of each $1,000 principal amount of Notes being converted, at the Company’s election, in full satisfaction of
the Company’s Conversion Obligation, (1) shares of Common Stock, together with cash in lieu of fractional shares, if any (a “Physical Settlement”), (2) a cash payment without any delivery of shares of
Common Stock (a “Cash Settlement”) or (3) a combination of cash and shares of Common Stock, together with cash in lieu of fractional shares, if any (a “Combination Settlement”), in
each case, as set forth below (the amounts so deliverable upon conversion of the Notes, the “Conversion Obligation”): 

For conversions: 

(i) that occur prior to April 15, 2018, by the close of business on the Business Day following the Conversion Date, the
Company shall notify converting Holders of the relevant Settlement Method and, if the Company elects a Combination Settlement, the dollar amount of the conversion obligation (the “Cash Amount”) that will be settled in cash; 

(ii) that occur on or after April 15, 2018, the Company shall notify all Holders of the relevant Settlement Method and, if
applicable, the related Cash Amount, by notice on or prior to April 15, 2018 (which shall apply to all conversions on or following April 15, 2018). 

If the Company does not specify a Settlement Method as set forth above, then Combination Settlement shall apply, and the related Cash Amount
used in the settlement calculation set forth in paragraph (d) below will be $1,000. Any such notice of a Settlement Method may not be revoked. 

(b) If the Company has elected a Physical Settlement with respect to any Notes tendered for conversion, the Company shall deliver, for each
$1,000 principal amount of Notes, a number of shares of Common Stock equal to the Conversion Rate, together with cash in lieu of fractional shares. Except for conversions upon a Make-Whole Fundamental Change as provided in Section 4.06,
the Company shall deliver such shares of Common Stock (1) on the third Business Day following the Conversion Date, in the case of a Physical Settlement with respect to a Conversion Date on or prior to the Business Day immediately preceding
April 15, 2018, or (2) on the third Business Day following the last day of the applicable Observation Period, in the case of a Physical Settlement with respect to a Conversion Date on or after April 15, 2018. 

(c) If the Company has elected a Cash Settlement with respect to any Notes tendered for conversion, the Company shall deliver, for each $1,000
principal amount of Notes, a cash payment equal to the sum of the Daily Conversion Values for each of the twenty (20) consecutive Trading Days during the relevant Observation 

  
 36 








 
Period. Except for conversions upon a Make-Whole Fundamental Change as provided in Section 4.06, the Company shall make such payment on the third Business Day following the last day
of the applicable Observation Period. 
 (d) If the Company has elected or is deemed to have elected a Combination Settlement with respect
to any Notes tendered for conversion, the Company shall deliver, for each $1,000 principal amount of Notes, the sum of the Daily Settlement Amounts for each of the twenty (20) consecutive Trading Days during the relevant Observation Period.

 The “Daily Settlement Amount” for each of the twenty (20) consecutive Trading Days during the Observation Period
shall consist of: 
 (i) cash in an amount equal to the lesser of (i) 5% of the cash amount specified by the Company in
the notice regarding the chosen Settlement Method (the “Daily Cash Amount”) and (ii) the Daily Conversion Value on such Trading Day; and 

(ii) if the Daily Conversion Value on such Trading Day exceeds the Daily Cash Amount, a number of shares of Common Stock
(together with cash in lieu of any fractional shares) equal to (i) the difference between such Daily Conversion Value and the Daily Cash Amount, divided by (ii) the Daily VWAP on such Trading Day. 

Except for conversions upon a Make-Whole Fundamental Change as provided in Section 4.06, the Company shall deliver such
cash and shares of Common Stock on the third Business Day following the last day of the applicable Observation Period. 
 (e)
Upon conversion of any Notes, Holders shall not receive any separate cash payment for accrued and unpaid interest, except to the extent specified below. The Company’s delivery to the Holder of Common Stock, cash or a combination of cash and
Common Stock, as applicable, together with any cash payment for any fractional share of Common Stock, into which a Note is convertible shall be deemed to satisfy in full the Company’s obligation to pay (i) the principal amount of the Notes
so converted and (ii) accrued and unpaid interest to, but not including, the Conversion Date. As a result, accrued and unpaid interest to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled,
extinguished or forfeited. 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 need be made (i) for conversions following the Regular Record Date immediately preceding April 15, 2018, (ii) if the Company has specified a
Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, (iii) if the Company has specified a date for redemption of Notes that is after a Regular Record Date and on or
prior to the corresponding Interest Payment Date, or (iv) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note. 

  
 37 








 (f) The Company shall not issue fractional shares of Common Stock upon conversion of Notes. If
multiple Notes shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or
specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of Common Stock would be issuable upon the conversion of any Notes, the Company shall make payment therefor in cash in lieu of fractional shares of
Common Stock based on: 
 (i) if Physical Settlement applies, on the Last Reported Sale Price of the Common Stock on the
relevant Conversion Date, and 
 (ii) if Combination Settlement applies, the Daily VWAP of the Common Stock on the final
Trading Day of the applicable Observation Period. 
 (g) Solely for purposes of determining the payments and deliveries due upon
conversion under this Section 4.03, and notwithstanding the definition of “Trading Day” contained in Section 1.02, “Trading Day” means a day on which (i) there is no Market Disruption
Event and (ii) trading in the Common Stock generally occurs on the New York Stock Exchange or, if the Common Stock is not then listed on the New York Stock Exchange, on the principal other United States national or regional securities exchange
on which the Common Stock is then listed or, if the Common Stock is not then listed on a United States national or regional securities exchange, on the principal other market on which the Common Stock is then traded. If the Common Stock (or other
security for which a Daily VWAP must be determined) is not so listed or traded, “Trading Day” means a Business Day. 

(h) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or Redemption Notice, the Company shall
deliver shares of Common Stock, cash or a combination of cash and shares of Common Stock, as set forth above, at the increased Conversion Rate as described in Section 4.06. 

SECTION 4.04. 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 will not make any adjustment to the Conversion Rate if Holders of Notes participate, as a result of holding the Notes, in any of the transactions described under
Section 4.04(a) (but only with respect to stock dividends or distributions), Section 4.04(b), Section 4.04(c), and Section 4.04(d), at the same
time as holders of the Common Stock participate, without having to convert their Notes, as if such Holders held a number of shares of Common Stock equal to the Conversion Rate in effect for each $1,000 principal amount of such Notes immediately
prior to the Ex-Dividend Date for such event. 

  
 38 








 (a) If the Company, at any time or from time to time while any of the Notes are outstanding,
exclusively issues shares of its Common Stock as a dividend or distribution on shares of Common Stock, or if the Company effects a share split or share combination, then 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;
		
	CR1  =	  	The Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or such effective date;
		
	OS0  =	  	The number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or such effective date; and
		
	OS1  =	  	The number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Such adjustment shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend
or distribution or the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 4.04(a) is declared but not so paid or made, the Conversion Rate shall again be
adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. 
 (b) If the
Company, at any time or from time to time while any of the Notes are outstanding, issues to all or substantially all holders of the Common Stock any rights or warrants entitling them for a period of not more than 45 calendar days after date of such
issuance to subscribe for or purchase shares of the Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately
preceding the Ex-Dividend Date for 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;
		
	CR1  =	  	The Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;


  
 39 









					
	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 or warrants; and
			
	Y	 	=	  	The number of shares of Common Stock equal to the aggregate price payable to exercise such rights 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 the Trading Day immediately preceding the date of announcement of the issuance of such rights or warrants.

 Such adjustment shall become effective immediately after the open of business on the Ex-Dividend Date for such
issuance. To the extent such rights or warrants are not exercised prior to their expiration or termination, the Conversion Rate shall be readjusted to the Conversion Rate which would be in effect had the adjustments made upon the issuance of such
rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion
Rate which would then be in effect if the date fixed for the determination of shareholders entitled to receive such rights or warrants had not been fixed. For the purposes of this Section 4.04(b), in determining whether any rights or
warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the
date of announcement of such issuance, and in determining the aggregate exercise price payable for such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount
payable on the exercise thereof, with the value of such consideration, if other than cash, as shall be determined by the Board of Directors. 

(c) If the Company, at any time or from time to time while the Notes are outstanding, distributes shares of any class of capital stock of the
Company, evidences of its indebtedness, other assets or property of the Company or rights or warrants to acquire the Company’s capital stock or other securities to all or substantially all holders of its Common Stock, excluding: 

(i) dividends or distributions and rights or warrants as to which an adjustment was effected pursuant to
Section 4.04(a) or Section 4.04(b); 
 (ii) dividends or distributions paid exclusively in cash (as
set forth below in Section 4.04(d)); and 

  
 40 








 (iii) Spin-Offs to which the provisions set forth below in this
Section 4.04(c) shall apply; then the Conversion Rate shall be adjusted based on the following formula: 
  





 
  

					
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	 	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	FMV	 	=	  	the fair market value (as determined by the Board of Directors) of the shares of capital stock, evidences of indebtedness, assets, property, rights or warrants distributed with respect to each outstanding share of the Common Stock
on the Ex-Dividend Date for such distribution

 Such adjustment shall become effective immediately after the open of business on the Ex-Dividend Date for such
distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 4.04(c) by reference to the actual or when issued trading market for any securities, it
must in doing so consider the prices in such market over the same period used in computing the average of the Last Reported Sale Prices of the Common Stock. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or
greater than “SP0” (as defined above), in lieu of the foregoing adjustment, each Holder of Notes shall receive, at the same time and upon the same terms as holders of the
Common Stock, the amount and kind of securities, assets and property such Holder would have received as if such Holder owned a number of shares of Common Stock equal to, for each $1,000 principal amount of Notes, the Conversion Rate in effect on the
record date for the distribution of the securities, assets or property. 
 With respect to an adjustment pursuant to this
Section 4.04(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
and such dividend or distribution is listed for trading on a 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 (as defined below);
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;


  
 41 









					
	FMV0	 	=	  	the average of the Last Reported Sale Prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined for purposes of the definition of Last Reported
Sale Price as if such capital stock or similar equity interest were the Common Stock) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”);
and
			
	MP0	 	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph will occur on the last day of the Valuation Period;
provided that in respect of any conversion during the Valuation Period, references above to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the
Conversion Date in determining the applicable Conversion Rate. 
 For the purposes of this Section 4.04(c) (and
subject in all respects to Section 4.12), rights 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 (either initially or under
certain circumstances), which rights or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and
(3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate under this Section 4.04(c)
will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and 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 4.04(c). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights 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 of such deemed distribution (in which case
the original rights or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights or warrants, or any Trigger Event or other
event (of the type described in the 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 4.04(c) was made,
(1) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise by any Holders thereof, upon such final redemption or repurchase (x) the Conversion Rate shall be readjusted as if such rights
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 holders of Common Stock with respect to such rights or warrants (assuming each such holder had retained such rights 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 or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.


  
 42 








 For the purposes of this Section 4.04(c) and subsections (a) and
(b) of this Section 4.04, any dividend or distribution to which this Section 4.04(c) applies which also includes one or both of: 

(A) a dividend or distribution of shares of Common Stock to which Section 4.04(a) applies (the “Clause A
Distribution”); and 
 (B) a dividend or distribution of rights or warrants to which Section 4.04(b)
applies (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 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 4.04(c)
with respect thereto 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 4.04(a) and
Section 4.04(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 such effective date” within the meaning of Section 4.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 4.04(b). 

(d) If the Company makes any cash dividend or distribution to all or substantially all holders of 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;
	CR1	 	=	 	The Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
	SP0	 	=	 	The Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
	C	 	=	 	The amount in cash per share the Company distributes to holders of the Common Stock.


  
 43 








 In the case of an adjustment pursuant to this Section 4.04(d), such adjustment shall become
effective immediately after the open of business on the Ex-Dividend Date for the relevant dividend or distribution. If the portion of the cash so distributed applicable to one share of the Common Stock is equal to or greater than the Last Reported
Sale Price of a share of Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution, in lieu of the adjustment set forth above, adequate provision shall be made so that each Holder of Notes shall
have the right to receive on the date on which such cash dividend or distribution is distributed to holders of Common Stock, for each $1,000 principal amount of Notes, the amount of cash such Holder would have received had such Holder owned a number
of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the Ex-Dividend Date for such distribution. 

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for Common Stock, to the extent
that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price per share of 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;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	AC	 	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares 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;
			
	OS1	 	=	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange
offer); and
			
	SP1	 	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer expires.


  
 44 








 The adjustment to the Conversion Rate under this Section 4.04(e) shall occur as of the close
of business on the tenth 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 10 Trading Days
immediately following, and including, the expiration date of any tender or exchange offer, references with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date
of such tender or exchange offer and the Conversion Date in determining the applicable Conversion Rate. 
 (f) The Company
from time to time may increase the Conversion Rate by any amount for any period of time of at least 20 Business Days, so long as the increase is irrevocable during the period and the Board of Directors shall have made a determination that such
increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to this Section 4.04 (f), the Company shall mail to Holders of record of the Notes a
notice of the increase at least one day 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. 

(g) The Company may (but shall not be required to) increase the Conversion Rate, in addition to any adjustments pursuant to
Section 4.04 (a), 4.04(b), 4.04(c), 4.04(d), 4.04(e) or 4.04(f), if the Board of Directors considers such increase to be advisable 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. 

(h) All calculations under this Article 4 shall be made by the Company and shall be made to the nearest cent (including, in the
case of any adjustment to the Conversion Rate, the resulting adjustment to the Conversion Price) or to the nearest one ten-thousandth of a share. No adjustment shall be required to be made for the Company’s issuance of Common Stock or any
securities convertible into or exchangeable for shares of Common Stock or rights to purchase shares of Common Stock or such convertible or exchangeable securities, other than as provided in this Section 4.04 and in
Section 4.11 hereof. 
 (i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file
with the Trustee and any Conversion Agent 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 and the Conversion Agent shall have received such Officers’ Certificate, neither the Trustee nor the Conversion Agent 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 of the Notes. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

  
 45 








 (j) For purposes of this Section 4.04, 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. 
 (k) Notwithstanding the foregoing, if the
application of the foregoing formulas set forth in this Section 4.04 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made (other than as a result of a reverse share split or share
combination). 
 (l) Notwithstanding anything to the contrary in this Article 4, no adjustment to the Conversion Rate shall be made:

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

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

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

(iv) for a change in the par value of the Common Stock; or 

(v) for accrued and unpaid interest on the Notes. 

(m) If a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder that has converted its Notes on
or after such Ex-Dividend Date and on or prior to the related record date would be treated as the record holder of shares of Common Stock as of the related Conversion Date as set forth in Section 4.02(e) based on an adjusted Conversion
Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions above, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be
deemed to be the record owner of shares of Common Stock on an unadjusted basis on such Conversion Date and participate in the related dividend, distribution or other event giving rise to such adjustment. 

  
 46 








 (n) In the event of an increase in the Conversion Rate that would result in the Notes, in the
aggregate, becoming convertible into Common Stock in excess of limitations imposed by the applicable certain listing standards of The New York Stock Exchange, the Company shall, at its option, either obtain stockholder approval of such issuances or
pay cash in lieu of delivering any shares of Common Stock otherwise deliverable on the Conversion Date 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 4.04(n). 
 SECTION 4.05. Certain Other
Adjustments. Whenever a provision of this Indenture requires the calculation of Last Reported Sale Prices or Daily VWAP over a span of multiple days, the Board of Directors will make appropriate adjustments to such Last Reported Sale Prices or
Daily VWAP, the Conversion Rate, or the amount due upon conversion to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event
occurs, at any time during the period from which such Last Reported Sale Prices or Daily VWAP are to be calculated. 
 SECTION 4.06.
Adjustments Upon Certain Fundamental Changes or Redemption Notices. (a) If (i) a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or (ii) on or
after October 15, 2016, the Company gives notice to Holders of the Company’s intention to redeem any or all of the Notes as provided under Article 15 hereof, 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 or Redemption Notice, as the case may be, if the notice of conversion or redemption of the Notes is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole
Fundamental Change or redemption up to, and including, the Business Day immediately prior to the related redemption or Fundamental Change Purchase Date (or, in the case of an event that would have been a Fundamental Change but for the proviso in
clause (2) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). A conversion of Notes will be deemed for these purposes to be “in connection with” a
Redemption Notice if the notice of conversion of the Notes is received by the Conversion Agent from, and including, the date of the Redemption Notice until the close of business on the Business Day preceding the Redemption Date. 

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall have the right to deliver, in
lieu of shares of Common Stock, including the Additional Shares, cash or a combination of cash and shares of Common Stock as provided under Section 4.03(a); provided, however, that if the consideration for the Common Stock in any
Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is comprised entirely of cash, then, for any conversion of Notes following the Effective Date of such
Make-

  
 47 








 
Whole Fundamental Change, the amounts deliverable by the Company shall be calculated based solely on the Stock Price for the Make-Whole Fundamental Change and shall be deemed to be an amount
equal to the applicable Conversion Rate (including any adjustment for Additional Shares described in this Section) multiplied by such Stock Price. In such event, the amounts deliverable by the Company shall be determined and paid to holders in cash
on the third Business Day following the Conversion Date. 
 (c) The number of Additional Shares, if any, by which the Conversion Rate will
be increased will be determined by reference to the table attached as Schedule A hereto, based on the date on which the Make-Whole Fundamental Change or the date of the Redemption Notice, as the case may be, occurs or becomes effective
(each, an “Effective Date”), and the price (the “Stock Price”) paid (or deemed paid) per share of the Common Stock in the Make-Whole Fundamental Change or the redemption, as the case may be. If the holders of the
Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (2) 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 preceding the Effective Date. 

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

(i) If the Stock Price is between two Stock Prices in the table 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 $250.00 per share (subject to adjustment in the same manner as the
Stock Prices set forth in the column headings of the table in Schedule A pursuant to subsection (d) below), no Additional Shares shall be added to the Conversion Rate. 

(iii) If the Stock Price is less than $36.50 per share (subject to adjustments in the same manner as the Stock Prices set forth
in the column headings of the table in Schedule A pursuant to subsection (d) below), no Additional Shares shall be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 27.3973 shares of Common Stock per $1,000 principal amount
of Notes, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 4.04. 
 (d) The Stock
Prices set forth in the column headings of the table in Schedule A hereto 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 

  
 48 








 
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 such table shall be adjusted in the same manner as the Conversion Rate as set forth in Section 4.04. 

(e) 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. 
 SECTION 4.07. Effect of Recapitalization,
Reclassification, Consolidation, Merger or Sale. (a) If any of the following events occur: 
 (i) any
recapitalization or reclassification of, or change in, the Common Stock (other than changes resulting from a subdivision or combination); 

(ii) a consolidation, merger or combination involving the Company; or 

(iii) a sale, lease or other transfer to a third party of the consolidated assets of the Company and its 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, or would be reclassified or changed into, stock, other
securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may
be, shall execute with the Trustee and the Agent a supplemental indenture providing that at and after the effective time of such Merger Event, the right to convert a Note will be changed into a right to convert such Note as set forth in this
Indenture 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 Conversation Rate prior to such Merger
Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the type and amount of Reference Property that a holder of one share of Common Stock is
entitled to receive) upon such Merger Event; provided, however, that at and after the effective time of the Merger Event the conversion obligation shall be calculated and settled in accordance with Section 4.03 such
that (i) the amount payable in cash upon conversion of the Notes as set forth under Section 4.03 will continue to be payable in cash, (ii) the number of shares of Common Stock (if the Company elects Physical Settlement or
Combination Settlement) deliverable upon conversion of the Notes under Section 4.03 will be instead deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled
to receive in such Merger Event and (iii) the Daily VWAP will be calculated based on the value of a unit of Reference Property. 

If, as a result of the Merger Event, each share of Common Stock is 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 (x)

  
 49 








 
the Reference Property into which the Notes will be convertible will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that
affirmatively make such an election, and (y) the unit of Reference Property for purposes of the foregoing sentence shall refer to the consideration referred to in clause (x) attributable to one share of Common Stock. 

The Company shall not become a party to any such Merger Event unless its terms are consistent with this Section 4.07(a).
Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 4 in the judgment of the Board of Directors or the board of directors of the
successor Person. If, in the case of any such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease, other transfer or statutory share exchange, the Reference Property receivable thereupon by a holder of Common
Stock 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 Person, as the case may be, in such reorganization, reclassification, change,
consolidation, merger, combination, sale, lease, other transfer or statutory share exchange, then such supplemental indenture shall also be executed by such other Person. 

(b) The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such
Holder as it appears on the register of the Notes maintained by the Note Registrar, within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above
provisions of this Section 4.07 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this Section 4.07 applies to any Merger Event,
Section 4.04 shall not apply. 
 SECTION 4.08. Taxes on Shares Issued. The Company will pay any
documentary, stamp or similar issue or transfer tax due on the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto; provided, however, that if such documentary, stamp or similar issue or transfer tax is due
because the Holder of such Notes has requested that shares of Common Stock be issued in a name other than that of the Holder of the Notes converted, then such taxes will be paid by the Holder, and the Company shall not be required to issue or
deliver any stock certificate evidencing such shares unless and until the Holder shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 

SECTION 4.09. Reservation of Shares; Shares to be Fully Paid; Compliance With Governmental Requirements; Listing of Common Stock.
The Company shall reserve, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to satisfy conversion of the Notes from time to time as such Notes are presented for conversion (assuming that, at
the time of the computation of such number of shares or securities, all such Notes would be converted by a single Holder and that Physical Settlement would apply). 

  
 50 








 The Company covenants that all shares of Common Stock that may be issued upon conversion of Notes
shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder). 

The Company shall list or cause to have quoted any shares of Common Stock to be issued upon conversion of Notes on each national securities
exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted. 
 SECTION 4.10. Responsibility
of Trustee and Conversion Agent. The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Notes to determine or calculate the Conversion Rate, to determine whether any facts exist which may
require any adjustment of the Conversion Rate, or to confirm the accuracy of any such adjustment when made or the appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The
Trustee and the 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 other securities or property that may at any time be issued or delivered upon the
conversion of any Notes; and the Trustee and the Conversion Agent make no representations with respect thereto. Neither the Trustee nor the 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 Notes for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this
Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee and the Conversion Agent, including without limitation its right to be compensated, reimbursed, and indemnified, are extended to, and shall be
enforceable by, the Trustee and the Conversion Agent in any other capacity either may hold hereunder, including, if either, is so appointed by the Company and accepts such appointment, as Bid Solicitation Agent. 

SECTION 4.11. Notice to Holders Prior to Certain Actions. In case: 

(a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in
the Conversion Rate pursuant to Section 4.04; or 
 (b) the Company shall authorize the granting to the holders
of all or substantially all of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants that would require an adjustment in the Conversion Rate pursuant to Section 4.04 or
Section 4.12 hereof; or 
 (c) of any reclassification or reorganization of the Common Stock of the Company
(other than a change in par value, or from par value to no par value, or 

  
 51 








 
from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale, lease or
transfer of all or substantially all of the assets of the Company and its consolidated Subsidiaries; or 
 (d) of the
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 and to be mailed to each Holder of Notes at such Holder’s address appearing on a list of
Holders of Notes, which the Company shall provide to the Trustee and the Conversion Agent, as promptly as practicable but in any event at least 10 calendar days prior to the applicable date hereinafter specified, a notice stating (x) the date
on which a record is to be taken for the purpose of such dividend (or any other distribution) or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights or warrants are to be determined, or (y) the date on which such reclassification, reorganization, consolidation, merger, sale, lease, transfer, 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 reclassification, reorganization, consolidation, merger,
sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend (or any other distribution), reclassification, reorganization, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up. 
 SECTION 4.12. Stockholder Rights Plan. Each share of Common Stock
issued upon conversion of Notes pursuant to this Article 4 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any,
in each case as may be provided by the terms of any stockholder rights plan adopted by the Company, as the same may be amended from time to time. Notwithstanding the foregoing, if prior to any conversion such rights have separated from the shares of
Common Stock in accordance with the provisions of the applicable stockholder rights agreement, the Conversion Rate shall be adjusted at the time of separation as if the Company had distributed to all holders of the Common Stock, shares of the
Company’s capital stock, evidences of indebtedness, assets, property, rights or warrants as described in Section 4.04(c) above, subject to readjustment in the event of the expiration, termination or redemption of such rights. 

  
 52 








 ARTICLE 5 

DEFAULTS AND REMEDIES 

SECTION 5.01. Events of Default. Each of the following shall be an “Event of Default”: 

(a) the Company defaults in the payment of interest, including any Additional Interest, on any Note when the same becomes due
and payable and such default continues for a period of 30 days, whether or not such payment is prohibited pursuant to Article 8; 

(b) the Company defaults in the payment of the principal of any Note when the same becomes due and payable at its Maturity,
upon acceleration, upon any required repurchase, upon optional redemption, or otherwise, whether or not such payment is prohibited pursuant to Article 8; 

(c) failure by the Company to comply with its obligation to convert the Notes in accordance with the Indenture upon exercise of
a Holder’s conversion right in accordance with Article 4 hereof, whether or not prohibited pursuant to Article 8; 

(d) failure by the Company to provide a Fundamental Change Company Notice pursuant to Section 3.01(b) or notice of
a specified corporate transaction required by Section 4.01(a)(iii) or Section 4.01(a)(iv) in accordance with the relevant Section, in each case when due; 

(e) failure by the Company to comply with its obligations under Section 6.01 hereof;

the acceleration of such indebtedness prior to its express maturity and the principal amount of any such indebtedness, together with the principal amount of any other such indebtedness the maturity of which has been so accelerated, aggregates $50.0
million or more and such acceleration has not been rescinded or annulled or such indebtedness discharged in full within 30 days; 

(i) the Company or any Significant Subsidiary of the Company pursuant to or within the meaning of any Bankruptcy Law:

an involuntary case, 
 (B) appoints a Bankruptcy Custodian of the Company or any Significant Subsidiary of the Company or a
Bankruptcy Custodian for all or substantially all of the property of any Significant Subsidiary of the Company, or 
 (C)
orders the liquidation of the Company or any Significant Subsidiary of the Company. 
 SECTION 5.02. Additional Interest.
Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating to any obligation to file documents and reports with the Trustee as required by Section 9.06 of
this Indenture shall for the first 180 days following the occurrence of such Event of Default consist exclusively of the right to receive additional interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes
outstanding for each during the 90-day period beginning on, and including, the occurrence of such Event of Default during which such Event of Default is continuing, and at a rate equal to 0.50% per annum of the principal amount of the Notes
outstanding for each day from the 91st day until the 364th day during which such Event of Default is continuing (in each case, “Additional Interest”). In order to elect to pay Additional Interest as the sole remedy during the first
364 days after the occurrence of an Event of 

  
 54 








 
Default described in the preceding sentence, the Company must give notice to Holders of the Notes, the Trustee and the Paying Agent of such election on or prior to the close of business on
the Business Day before the date on which such Event of Default would occur and on or prior to the close of business on the 91st day after the date on which such Event of Default first occurs. If the Company so elects, such Additional Interest shall
be payable in the same manner and on the same dates as the stated interest payable on the Notes. Upon the failure to timely give all Holders, the Trustee and the Paying Agent such notice, the Notes will be subject to immediate acceleration as
provided in Section 5.03 of this Indenture. On the 365th day after such Event of Default occurs (if such Event of Default is not cured or waived prior to such 365th day), the Notes shall be subject to acceleration as provided in
Section 5.03 of the Indenture. This Section 5.02 shall not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. Whenever in the Indenture there is mentioned, in any context, the
payment of interest on, or in respect of, any Note, such mention shall be deemed to include mention of the payment of Additional Interest provided for in this Section 5.02 to the extent that, in such context, Additional Interest is, was
or would be payable in respect thereof pursuant to the provisions of this Section 5.02, and express mention of the payment of Additional Interest (if applicable) in any provision shall not be construed as excluding Additional Interest in
those provisions where such express mention is not made. 
 SECTION 5.03. Acceleration. Subject to the provisions of
Section 5.02, if an Event of Default occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the outstanding Notes by notice to the Company and the Trustee, may, and
the Trustee at the request of such holders shall, declare 100% of the principal of and accrued and unpaid interest on all the Notes to be due and payable. Upon such a declaration of acceleration, all principal and accrued and unpaid interest
(including any Additional Interest) on the Notes will be due and payable immediately. However, upon an Event of Default arising out of Sections 5.01(i) or 5.01(j), the aggregate principal amount and accrued and unpaid interest
(including any Additional Interest) will be due and payable immediately, without any declaration, notice or other act on the part of the Trustee or Holder. The Holders of a majority in principal amount of the then outstanding Notes affected by such
Event of Default, by written notice to the Trustee, may rescind an acceleration and its consequences (other than nonpayment of principal of or premium, if any, or interest on or any Additional Interest with respect to the Notes) if the rescission
would not conflict with any judgment or decree and if all existing Events of Default with respect to the Notes have been cured or waived, except nonpayment of principal, premium, if any, interest or any Additional Interest that has become due solely
because of the acceleration. 
 SECTION 5.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause
(a) or (b) of Section 5.01 shall have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the holders of the Notes, the whole amount then due and payable on the Notes for
principal, premium, if any, and interest, with interest on any overdue principal, premium, if any, interest, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due
to the Agent and the 

  
 55 








 
Trustee under Section 11.06. 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 monies
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 any Bankruptcy 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 5.04, 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 premium, if any, and accrued and unpaid interest 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 of Notes allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors,
or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 11.06; and any
receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders of Notes 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 of Notes, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agent’s and counsel fees and
expenses, and including any other amounts due to the Trustee under Section 11.06 hereof, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements
out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the holders of
the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of
Notes any plan of reorganization, arrangement, adjustment or composition affecting the Holder of Notes or the rights of any Holder of Notes thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of Notes in any such
proceeding. 

  
 56 








 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 such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders of Notes, 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 of Notes, and the Trustee shall continue as though no such proceeding had
been instituted. 
 SECTION 5.05. Application of Monies Collected by the Agent or the Trustee. Any monies collected by the Agent or
the Trustee pursuant to this Article 5 with respect to the Notes shall be applied in the order following, at the date or dates fixed by the Agent or 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 and/or the Agent under Section 11.06; 
 Second, in case the principal of the outstanding
Notes shall not have become due and be unpaid, to the payment of interest on the Notes, including any Additional Interest, in default in the order of the date due of the installments of such interest, with interest (to the extent that such interest
has been collected by the Agent or the Trustee) upon the overdue installments of interest 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 the payment of the Fundamental Change Purchase Price and the cash component of the Conversion Obligation, if any, then owing and unpaid 

  
 57 








 
upon the Notes for principal and premium, if any, and interest, including any Additional Interest, with interest on the overdue principal and premium, if any, 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, 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 and premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, 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 and premium, if any, and accrued and unpaid interest; and 

Fourth, to the payment of the remainder, if any, to the Company. 

SECTION 5.06. Proceedings by Holders of Notes. 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 such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of not less than 25% in aggregate principal
amount of the Notes then outstanding shall have made written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and 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, and 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 no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the holders of a majority in principal amount of the Notes outstanding within such 60-day period pursuant to
Section 5.09; 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 Noteholders shall have any right in any manner
whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Noteholder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such
actions or forbearances are unduly prejudicial to such Noteholders), 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 Noteholders (except as otherwise provided herein). For the protection and enforcement of this Section 5.06, each and every Noteholder 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 of Notes to (i) receive payment of principal of and premium, if any, and interest and any Additional Interest when due, (ii) receive payment or delivery of the consideration due upon conversion, (iii) receive the Fundamental
Change Purchase Price when due, (iv) receive the Redemption Price when due in 

  
 58 








 
connection with an optional redemption or (v) bring suit for the enforcement of any of (i), (ii), (iii) and (iv) above, is absolute and unconditional and shall not be impaired or
affected without the consent of such Holder. 
 Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any
Note, without the consent of either the Trustee or the holder of any other Note, on its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein.

 SECTION 5.07. 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 5.08. Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07 and
Section 5.02, all powers and remedies given by this Article 5 to the Trustee or to the Noteholders 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 any acquiescence therein; and, subject to the
provisions of Section 5.06, every power and remedy given by this Article 5 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the
Noteholders. 
 SECTION 5.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders of Notes. The Holders of a
majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 12.04 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 Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 12.04 by notice to the Trustee may waive an existing or past Default or
Event of Default with respect to such Notes and its consequences, except (1) a continuing Default or Event of Default in the payment of premium, accrued and unpaid interest or any accrued and unpaid Additional Interest on, or the principal
(including any 

  
 59 








 
Fundamental Change Purchase Price or the Redemption Price in connection with an optional redemption) of, the Notes when due, (2) a continuing Default or Event of Default in the payment
or delivery of any consideration due upon conversion of any Note, or (3) a continued Default in respect of a provision that under Article 7 cannot be amended or supplemented without the consent of each Holder affected. Upon any such
waiver, 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 shall extend to any subsequent or other Default or impair any right
consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 5.09, 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 5.10. Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of
a Default or Event of Default of which a Responsible Officer has actual knowledge, mail to all Noteholders as the names and addresses of such holders appear upon the Note Register, notice of all Defaults or Events of Default known to a Responsible
Officer, unless such Defaults or Events of Default shall have been cured or waived before the giving of such notice; and provided that, except in the case of a Default or in the payment of the principal of, or premium, if any,
accrued and unpaid interest including any accrued and unpaid Additional Interest on any of the Notes, including without limiting the generality of the foregoing any Default or Event of Default in the payment of any Fundamental Change Purchase Price,
the Redemption Price in connection with an optional redemption, or a Default or Event of Default in the payment or delivery of consideration due upon conversion of the Notes, then in any such event the Trustee shall be protected in withholding such
notice if and so long as a committee of Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders. 

SECTION 5.11. 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 Agent or the Trustee for any action taken
or omitted by it as Agent or Trustee (as applicable), 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 5.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the
Notes at the time outstanding determined in accordance with Section 12.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, accrued and unpaid interest, if any, on any
Note (including, but not limited to, the Fundamental Change Purchase 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 4.

Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indenture comply with this Article and that all conditions precedent provided for in the Indenture relating to such transaction
have been complied with.

is merged or to which such sale, lease, conveyance, transfer or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of the Company under this Indenture and the Securities with the same effect as
if such Successor had been named as the Company herein and the predecessor Company, in the case of a sale, conveyance, transfer or other disposition, shall be released from all obligations under this Indenture and the Securities.

 63 








 It shall not be necessary for the consent of the Noteholders under this
Section 7.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. After an amendment under this Indenture becomes effective, the Company

SECTION 7.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of
this Article 7, 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,

ARTICLE 8 

SUBORDINATION OF NOTES 

SECTION 8.01. Notes Subordinate to Senior Indebtedness. The Company covenants and agrees, and each holder of a Note, whether
upon original issue or upon registration of transfer, assignment or exchange hereof, by his acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article 8, the
indebtedness represented by the Notes and the payment of  

  
 64 








 
the principal amount, premium, if any, any cash portion of the Conversion Obligation in respect of, and interest on all Notes (including, but not limited to, the Fundamental Change Purchase
Price with respect to the Notes subject to repurchase in accordance with Article 3 as provided in this Indenture) (collectively, the “Subordinated Obligations”) are hereby expressly made subordinate and junior in right of
payment to the prior payment in full in cash or other payment satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness and that said subordination is for the benefit of the holders of Senior Indebtedness and they and/or each of
them severally may enforce such subordination. The Notes will be pari passu in right of payment to all Senior Subordinated Indebtedness of the Company and senior in right of payment to all Subordinated Indebtedness of the
Company. 
 SECTION 8.02. Payment Over of Proceeds Upon Dissolution, Etc. In the event of (a) any dissolution,
insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any
liquidation, dissolution or other winding up of the Company, in each case whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshaling of
assets and liabilities of the Company upon any payment or distribution of the Company’s assets or securities, then and in any such event the holders of Senior Indebtedness shall be entitled to receive payment in full in cash, or other payment
satisfactory to the holders of Senior Indebtedness, of all amounts due or to become due on or in respect of all Senior Indebtedness before the holders of the Notes are entitled to receive any payment or distribution on account of the Subordinated
Obligations, and to that end the holders of Senior Indebtedness or their representative or representatives or the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued,
shall be entitled to receive from the liquidating trustee or agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, ratably according to the aggregate amounts
remaining unpaid on account of the Senior Indebtedness held or represented by each, to the extent necessary to make payment in full in cash or other payment satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness remaining
unpaid, for application to the payment thereof, any payment or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in respect of the Subordinated Obligations in any such case,
proceeding, dissolution, liquidation or other winding up or event, assignment or marshalling. 
 The consolidation of the
Company with, or the merger of the Company with or into, another Person or the liquidation or dissolution of the Company following the sale, conveyance, transfer or lease of all or substantially all of its properties and assets to another Person
upon the terms and conditions set forth in Article 6 hereof shall not be deemed a dissolution, winding up, liquidation, reorganization, assignment for the benefit of creditors or marshaling of assets and liabilities of the Company for the
purposes of this Section 8.02 if the Person formed by such consolidation or with or into which the Company is merged or which acquires by sale, conveyance, transfer or lease all or substantially all of such properties and assets, as the
case may be, shall, as a part of such consolidation, merger, sale, conveyance, lease or transfer, comply with the conditions set forth in Article 6 hereof.

 SECTION 8.03. No Payment When Senior Indebtedness in Default. (a) The Company
may not make any payment of or distribution with respect to the Subordinated Obligations nor may the Company acquire, defease or repurchase any Notes if (i) a payment default on any Senior Indebtedness has occurred and is continuing with
respect thereto (unless and until such payment default shall have been cured or waived in writing by the holders of such Senior Indebtedness); or (ii) a default (other than a default referred to in the preceding clause (i)) on any Designated
Senior Indebtedness occurs and is continuing that permits holders of such Senior Indebtedness to accelerate the maturity thereof and either such default is the subject of judicial proceedings or the Paying Agent receives a written notice of default
thereof that blocks payment under the Notes from any Person who may give such notice pursuant to the instrument evidencing or document governing such Designated Senior Indebtedness (a “Senior Indebtedness Default
Notice”). If the Company receives a Senior Indebtedness Default Notice, then a similar notice received within nine months thereafter relating to the same default on the same issue of Senior Indebtedness shall not be effective to
prevent the payment or acquisition of the Notes for purposes of this Section 8.03. 
 The Company may
resume payment on the Notes and may acquire Notes for cash if and when (x) the default referred to in clause (i) or (ii) of the preceding paragraph above is cured or waived in writing or ceases to exist; or (y) in the case of a
default referred to in clause (ii) of the preceding paragraph, 179 or more days pass after the receipt by the Company of the Senior Indebtedness Default Notice, and this Article 8 otherwise permits the payment or acquisition at that
time. 
 Nothing contained in this Article 8 or elsewhere in this Indenture or in any of the Notes shall prevent the
conversion by a holder of any Notes into shares of Common Stock in accordance with the provisions for conversion of such Notes set forth in this Indenture. 

(b) In the event of an acceleration of the Notes as a result of an Event of Default, then and in such event the Company shall promptly
notify holders of Senior Indebtedness of such acceleration. The Company may not pay, or make any distribution with respect to, the Notes until the earlier of (i) the passage of 120 or more days have passed after such acceleration occurs or
(ii) the payment in full in cash or other payment satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness, and may thereafter pay, or make any distribution with respect to, the Notes if this Article 8 permits the
payment or distribution at that time. 
 (c) In the event that, notwithstanding the foregoing provisions, any payment or
distribution of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by this Article 8, shall be received by the Paying Agent or the holders of the
Notes before all Senior Indebtedness is paid in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, such payment or distribution shall be held in trust for the 


  
 66 








 
benefit of and shall be paid over or delivered to the holders of Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness
in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution, or provision therefor, to or for the holders of such Senior Indebtedness. 

SECTION 8.04. Payment Permitted If No Default. Nothing contained in this Article 8 or any other provision
relating to subordination elsewhere in this Indenture or in any of the Notes shall prevent the Company, at any time except in the circumstances described in Section 8.02 and Section 8.03, from
making payments at any time of the principal amount of the Notes, any cash portion of the Conversion Obligation, interest, the repurchase price with respect to Notes submitted for repurchase in accordance with Article 3, as
the case may be, as provided in this Indenture. 
 SECTION 8.05. Subrogation to Rights of Holders of Senior Indebtedness.
Subject to the payment in full of all Senior Indebtedness in cash, and until the Notes are paid in full, the holders of the Notes shall be subrogated (equally and ratably with the holders of all Senior Subordinated Indebtedness) to the rights of
the holders of such Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness to the extent that payments and distributions otherwise payable to holders of Notes have been
applied to the payment of Senior Indebtedness as provided by this Article 8. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which
the Holders of the Notes or the Paying Agent would be entitled, except for the provisions of this Article 8, and no payments over pursuant to the provisions of this Article 8 to the holders of Senior
Indebtedness by Holders of the Notes or the Paying Agent, shall, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Notes, be deemed to be a payment or distribution by the Company to or on account of
the Notes. 
 SECTION 8.06. Provisions Solely To Define Relative Rights. The provisions of this Article
8 are and are intended solely for the purpose of defining the relative rights of the holders of the Notes on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article 8
or elsewhere in this Indenture or in the Notes is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the holders of the Notes, the obligation of the Company, which is absolute and
unconditional (and which, subject to the rights under this Article 8 of the holders of Senior Indebtedness, is intended to rank equally with all other general obligations of the Company), to pay to the holders of the Notes the
principal amount of the Notes, any cash portion of the Conversion Obligation, interest, the repurchase price with respect to Notes submitted for repurchase in accordance with Article 3, as the case may be, as provided in this
Indenture as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights against the Company of the holders of the Notes and creditors of the 


  
 67 








 
Company other than the holders of Senior Indebtedness; or (c) prevent the Paying Agent or the Holder of any Note from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article 8 of the holders of Senior Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Paying Agent or such holder. If the
Company fails, as a result of this Article 8, to pay to the holders of the Notes the principal amount of the Notes, any cash portion of the Conversion Obligation, interest, the repurchase price with respect to Notes submitted for repurchase
in accordance with Article 3, as the case may be, as provided in this Indenture as and when the same shall become due and payable in accordance with their terms, such failure shall still constitute a Default or an Event of Default.

 SECTION 8.07. Paying Agent to Effectuate Subordination. Each holder of a Note by his acceptance thereof authorizes and
directs the Paying Agent on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 8 and appoints the Paying Agent his attorney-in-fact for any and all such
purposes. 
 SECTION 8.08. No Waiver of Subordination Provisions. No right of any present or future holder of any
Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by
any non-compliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. 

Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from
time to time, without the consent of or notice to the Paying Agent or the holders of the Notes, without incurring responsibility to the holders of the Notes and without impairing or releasing the subordination provided in this Article 8 or
the obligations hereunder of the holders of the Notes to the holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew, exchange, increase or
alter, Senior Indebtedness, or otherwise amend, modify or supplement in any manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness or any security thereof or guarantee thereof is
outstanding; (ii) sell, exchange, release, surrender, realize upon, enforce or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; (iv) exercise or refrain from exercising any rights against the Company and any other Person; (v) apply any and all sums received from time to time to the Senior Indebtedness; provided that if
any Senior Indebtedness is amended to provide that it shall be subordinated to any other Senior Indebtedness, such amended Senior Indebtedness shall no longer be considered Senior Indebtedness for purposes of this Article 8. 

  
 68 








 The provisions of this Article 8 shall continue to be effective or be reinstated as the
case may be if at any time any payment of the Senior Indebtedness is rescinded or must otherwise be returned by the holder thereof upon the insolvency, bankruptcy or reorganization of the Company or otherwise, all as though such payment had not been
made. 
 SECTION 8.09. Notice to Paying Agent. The Company shall give prompt written notice to Responsible Officers of the
Paying Agent of any fact known to the Company which would prohibit the making of any payment to or by the Paying Agent in respect of the Notes. Notwithstanding the provisions of this Article 8 or any other provision of this
Indenture, the Paying Agent shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or distribution by the Paying Agent in respect of the Notes, unless and until a Responsible Officers of
the Paying Agent shall have received written notice thereof from the Company or a holder of Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such written notice, the Paying Agent, subject to the provisions of
Section 11.01, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Paying Agent shall not have received the notice provided for in this
Section 8.09 at least two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose, then, anything herein contained to the contrary notwithstanding, the Paying Agent shall
have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within two Business Days prior to such
date. 
 Subject to the provisions of the Indenture, the Paying Agent shall be entitled to rely conclusively on the delivery
to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a trustee therefor) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee therefor). In the event that the
Paying Agent determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article 8 (although the Paying
Agent is not obligated to make such determination), the Paying Agent and the Agent (as applicable) may request such Person to furnish evidence to the reasonable satisfaction of the Paying Agent as to the amount of Senior Indebtedness held by such
Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 8, and if such evidence is not furnished, the Paying Agent
may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

SECTION 8.10. Reliance on Judicial Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the
Company referred to in this Article 8, the Paying Agent, subject to the provisions of the Indenture, and the holders of the Notes shall be entitled to conclusively rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian,
assignee for the benefit of creditors, agent or other Person making such  

  
 69 








 
payment or distribution, delivered to the Paying Agent or to the holders of Notes, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 8. 

SECTION 8.11. Paying Agent Not Fiduciary for Holders of Senior Indebtedness. The Paying Agent shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness and (subject to Section 8.09 hereof) shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to holders of Notes or to the
Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article 8 or otherwise. 

SECTION 8.12. Rights of Paying Agent as Holder of Senior Indebtedness; Preservation of Paying Agent’s Rights. The Paying
Agent in its individual capacity shall be entitled to all the rights set forth in this Article 8 with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Paying Agent of any of its rights as such holder. 
 Nothing in
this Article 8 shall apply to claims of, or payments to, the Trustee or the Paying Agent under or pursuant to Section 11.06. 

SECTION 8.13. [Reserved]. 

SECTION 8.14. No Senior Subordinated Indebtedness. The Company shall not, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to any indebtedness that is subordinate or junior in right of payment to any Senior Indebtedness and senior in right of payment to the Notes.

 SECTION 8.15. Amendment of Subordination Provisions. Any Senior Indebtedness will continue to be Senior Indebtedness
and will be entitled to the benefits of the subordination provisions of this Article 8 irrespective of any amendment, modification or waiver of any of such subordination provisions.

sum sufficient to pay such principal, premium (including the Fundamental Change Purchase Price or the Redemption Price in connection with an optional redemption), if any, 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, however, that to the extent any such funds are received by the Paying Agent from the Company after 11:00 a.m. (local time in The City of New

document or other report that the Company files with the Commission pursuant to Section 13 or 15(d) of the Exchange Act on the Commission’s EDGAR system shall be deemed to constitute delivery of such filing to the Agent as of the time such

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

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, as such rule may be amended from time to time 

  
 73

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 or the Agent, but will

SECTION 9.09. Further Instruments and Acts. 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. 
 SECTION 9.10.
Rule 144A Information. (a) 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 current reports on Form 8-K), or the Notes
are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months preceding (as a result of restrictions pursuant to U.S. securities laws or
the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. In such circumstances, for the first 90 days, Additional Interest shall accrue on the Notes at the rate of 0.25% per annum and for the remaining
period at a rate of 0.50% per annum, in each case, of the principal amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is continuing or the Notes are not otherwise
freely tradable by Holders other than the Company’s Affiliates (or Holders that have been the Company’s Affiliates at any time during the three months preceding) without restrictions pursuant to U.S. securities laws or the terms of this

Holders that were the Company’s Affiliates at any time during the three months preceding as of the 370th 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
(i) 0.25% per annum of the principal amount of Notes outstanding for the first 90 days and (ii) 0.50% per annum of the principal amount of Notes outstanding following the first 90 days and, in the case of both clauses
(i) and (ii), until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes are assigned an unrestricted CUSIP and the Notes are freely tradable by Holders other than the Company’s
Affiliates (or Holders that were the Company’s Affiliates at any time during the three months preceding) (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes). 

(c) Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on
the Notes. 
 (d) Notwithstanding anything herein to the contrary, at no time shall the Company be required to pay both the Additional
Interest that is payable in accordance with Section 9.10(a) or Section 9.10(b) and any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 5.02. 

(e) If Additional Interest is payable by the Company pursuant to Section 9.10(a) or Section 9.10(b), the Company shall
deliver to the Trustee and the Paying Agent an Officer’s Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a
Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons
entitled to it, the Company shall promptly deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment.

the Paying Agent, semi-annually, not more than fifteen days after each January 15 and July 15 in each year, beginning with January 15, 2010, and at such other times as the Trustee and the Paying Agent may request in writing, within
30 days after receipt by the Company of any such request (or such lesser time as the Trustee and the Paying Agent 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 and the Paying Agent may reasonably require of the names and addresses of the Noteholders as of a date not more than fifteen days (or such other date as the Trustee and the Paying Agent may reasonably request in order to so provide any

ARTICLE 11 
 CONCERNING
THE TRUSTEE AND THE AGENT 
 SECTION 11.01. Duties and Responsibilities of Trustee and Agent. The Trustee, except during
the occurrence of an Event of Default, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee. In case an
Event of Default has occurred (which 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. 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 or the Agent from liability for its own negligent action, its own
negligent failure to act or its own intentional misconduct, except that: 

  
 76 








 (a) prior to the occurrence of an Event of Default and after the curing or

SECTION 11.04. Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. The Trustee, any Paying Agent, any

Agent from time to time, and the Trustee and the Agent shall be entitled to, such compensation as shall be agreed  

  
 80

compensation of a trustee of an express trust), and the Company will pay or reimburse the Trustee and the Agent upon their request for all reasonable expenses, disbursements and advances reasonably incurred or made and reasonably documented by the
Trustee and the Agent 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 or intentional misconduct. The Company also covenants to indemnify the Trustee and the Agent in any capacity under this Indenture and any
other document or transaction entered into in connection herewith and to hold it harmless against, any and all loss, claim, damage, liability or expense, including taxes (other than taxes based on the income of the Trustee and the Agent), incurred
without gross negligence or intentional misconduct on the part of the Trustee or the Agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending
the Trustee or the Agent against any claim (whether asserted by the Company, a Noteholder or any other Person) of liability in the premises. The obligations of the Company under this Section 11.06 to compensate or indemnify the Trustee
and the Agent and to pay or reimburse the Trustee and the Agent 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 or
the Agent, except, subject to the effect of Section 5.05, funds held in trust herewith for the benefit of the holders of particular Notes. The Trustee’s or Agent’s right to receive payment of any amounts due under this
Section 11.06 shall not be subordinate to any other liability or Indebtedness of the Company (even though the Notes may be so subordinated). The obligations of the Company under this Section 11.06 shall survive the
satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee or the Agent, as the case may be. 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 11.06 shall survive the termination or defeasance of this Indenture and the resignation or removal of the Trustee or the Agent, as the case may be. The Trustee or the Agent shall
notify the Company promptly of any claim of which a Responsible Officer receives written notice for which it may seek indemnity. 

Without prejudice to any other rights available to the Trustee or the Agent under applicable law, when the Trustee, the Agent and their
agents and any authenticating agent incur expenses or render services after an Event of Default specified in clauses (i) or (j) of Section 5.01 occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any bankruptcy, insolvency or similar laws. 
 SECTION 11.07. Officers’
Certificate as Evidence. Except as otherwise provided in Section 11.01, whenever in the administration of the provisions of this Indenture the Trustee or the Agent shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such matter  

  
 81 








 
(unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee or
the Agent, and such Officers’ Certificate shall be full warrant to the Trustee or the Agent for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 

SECTION 11.08. [Reserved]. 

SECTION 11.09. Eligibility of Trustee and Agent. There shall at all times be a Trustee hereunder that is a corporation organized
and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that
has a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. 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 11.10. Resignation or Removal of Trustee. (a) The Trustee and the Agent (as applicable) may at any time resign by
giving written notice of such resignation to the Company and by mailing notice thereof to the Noteholders 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 or agent (as applicable) 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 or Agent (as applicable) and one copy to the
successor trustee or agent (as applicable). If no successor trustee or agent (as applicable) shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation to the Noteholders, the resigning
Trustee or Agent (as applicable) may, upon ten Business Days’ notice to the Company and the Noteholders, petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee or agent (as
applicable), or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 5.11, on behalf of himself and all others similarly situated, petition any
such court for the appointment of a successor trustee or agent (as applicable). Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee or agent (as applicable). 

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

(i) the Trustee or Agent (as applicable) shall fail to comply with Section 11.08 within a reasonable time after
written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six months, or 

  
 82 








 (ii) the Trustee or Agent (as applicable) shall cease to be eligible in
accordance with the provisions of Section 11.09 and shall fail to resign after written request therefor by the Company or by any such Noteholder, or 

(iii) the Trustee or Agent (as applicable) shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

then, in any such case, the Company may by a Board Resolution remove the Trustee or Agent (as applicable) and appoint a successor
trustee or agent (as applicable) by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee or Agent so removed and one copy to the successor trustee or agent (as
applicable), or, subject to the provisions of Section 5.11, any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee or Agent (as applicable) and the appointment of a successor trustee or agent (as applicable). Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the
Trustee or Agent (as applicable) and appoint a successor trustee or agent (as applicable). 
 (c) The holders of a majority in
aggregate principal amount of the Notes at the time outstanding, as determined in accordance with Section 12.04, may at any time remove the Trustee or Agent (as applicable) and nominate a successor trustee or agent (as applicable) that
shall be deemed appointed as successor trustee or agent (as applicable) unless within ten days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee or Agent (as applicable) so removed or any
Noteholder, upon the terms and conditions and otherwise as in Section 11.10(a) provided, may petition, at the expense of the Company, any court of competent jurisdiction for an appointment of a successor trustee or agent (as
applicable). 
 (d) Any resignation or removal of the Trustee or Agent (as applicable) and appointment of a successor trustee
or agent (as applicable) pursuant to any of the provisions of this Section 11.10 shall become effective upon acceptance of appointment by the successor trustee or agent (as applicable) as provided in Section 11.11.

 SECTION 11.11. Acceptance by Successor Trustee or Agent. Any successor trustee or agent appointed as provided in
Section 11.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee or agent an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor
trustee or agent shall become effective and such successor trustee or agent, without any further act, deed or conveyance, shall become vested with  

  
 83 








 
all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee or agent herein; but, nevertheless, on the written request of
the Company or of the successor trustee or agent, the trustee or agent ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 11.06, execute and deliver an instrument transferring to such
successor trustee or agent all the rights and powers of the trustee or agent so ceasing to act. 
 Upon the reasonable written
request of any such successor trustee or agent, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee or agent all such rights and powers. Any trustee or Agent
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 or agent 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 11.06. 
 No successor
trustee or agent shall accept appointment as provided in this Section 11.11 unless at the time of such acceptance such successor trustee or agent shall be qualified under the provisions of Section 11.08 and be eligible under
the provisions of Section 11.09. 
 Upon acceptance of appointment by a successor trustee or agent as provided in this
Section 11.11, each of the Company and the successor trustee or agent, 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 or agent hereunder to the
Noteholders at their addresses as they shall appear on the Note Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee or agent, the successor trustee or agent shall cause such
notice to be mailed at the expense of the Company. 
 SECTION 11.12. Succession by Merger, Etc. Any corporation or
other entity into which the Trustee or Agent 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 or Agent shall be a party,
or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee or the Agent, as the case may be (including the administration of this Indenture), shall be the successor to the Trustee or the
Agent 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 or the Agent (as applicable), such corporation or other entity shall be qualified under the provisions of Section 11.08 and eligible under the provisions of Section
11.09. 
 In case at the time such successor to the Trustee or the Agent, as the case may be, 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 or Agent may adopt the certificate of authentication of any predecessor authenticating agent, and deliver


  
 84 








 
such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Authenticating Agent may authenticate such Notes either in the
name of any predecessor trustee or agent hereunder or in the name of the successor trustee or agent; 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 Authenticating Agent shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Authenticating Agent or to authenticate Notes in the name of any predecessor Authenticating
Agent shall apply only to its successor or successors by merger, conversion or consolidation. 
 SECTION 11.13. [Reserved]. 

 SECTION 11.14. Trustee’s or Agent’s Application for Instructions from the Company. Any application by the Trustee
or Agent 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 or Agent that affects the rights of the holders of the Notes under this Indenture) may, at the option
of the Trustee or the Agent, set forth in writing any action proposed to be taken or omitted by the Trustee or the Agent under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. Neither
the Trustee nor the Agent shall be liable for any action taken by, or omission of, the Trustee or the Agent, as the case may be, in accordance with a proposal included in such application on or after the date specified in such application (which
date shall not be less than three Business Days after the date any officer that the Company has indicated to the Trustee and the Agent should receive such application actually receives such application, unless any such officer shall have consented
in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee and the Agent shall have received written instructions in accordance with this Indenture in response to such
application specifying the action to be taken or omitted. 
 ARTICLE 12 

CONCERNING THE NOTEHOLDERS 

SECTION 12.01. Action by Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate
principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the
Noteholders voting in favor thereof at any meeting of Noteholders, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Company, the Agent or the Trustee solicits the
taking of any action by the holders of the Notes, the Company, the Agent or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining Noteholders 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. 

  
 85 








 SECTION 12.02. Proof of Execution by Noteholders. Subject to the provisions of
Section 11.01 and Section 11.02, proof of the execution of any instrument by a Noteholder 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 the Agent or in such manner as shall be satisfactory to the Trustee or the Agent. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. 

SECTION 12.03. Who Are Deemed Absolute Owners. The Company, the Trustee, the Agent, 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, premium, if any, 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 so made to any holder for the time being, or upon its order, shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies
payable 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 12.04. Company-Owned Notes Disregarded. In determining whether the holders of the requisite aggregate principal
amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common
control with the Company shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee or the Agent shall be protected in relying on any such
direction, consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this
Section 12.04 if the pledgee shall establish to the satisfaction of the Trustee or the Agent the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company or a Person directly or
indirectly controlling or controlled by or under direct or indirect common control with the Company. In the case of a dispute as to such right, any decision by the Trustee or the Agent 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 or the Agent promptly an Officers’ Certificate listing and  

  
 86 








 
identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 11.01, the Trustee or
the Agent 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 12.05. Revocation of Consents; Future Noteholders Bound. At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 12.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of a Note
that is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee and the Agent at their Corporate Trust Office and upon proof of holding as provided in
Section 12.02, 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.

verification report as to the sufficiency of the deposited amount from an independent certified accountant or other financial professional reasonably satisfactory to the Paying Agent (which may include any of the Initial Purchasers), and if the
Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect  

  
 87

beneficiaries hereof with respect to the amounts, if any, so deposited with the Paying Agent and (B) the rights, obligations and immunities of the Paying Agent hereunder), and the Paying Agent, on written demand of the Company accompanied by an
Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture; the Company, however, hereby agrees to reimburse the Paying

Holders of the particular Notes for the payment or redemption of which such monies have been deposited with the Paying Agent, of all sums due and to become due thereon for principal and interest, if any. 

SECTION 13.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies then held by
the Paying Agent shall, upon written request of the Company, be repaid to it, and thereupon such Paying Agent shall be released from all further liability with respect to such monies. 

SECTION 13.04. Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies deposited with or paid to
the Paying Agent for payment of the principal of or interest, if any, on the Notes and not applied but remaining unclaimed by the Holders of the Notes for two years after the date upon which the principal of or interest, if any, on such Notes, as
the case may be, shall have become due and payable, shall be repaid to the Company by the Paying Agent on demand, and all liability of the Paying Agent shall thereupon cease with respect to such monies; and the Holder of any of the Notes shall
thereafter look only to the Company for any payment that such Holder of the Notes may be entitled to collect unless an applicable abandoned property law designates another Person. 

SECTION 13.05. Reinstatement. If the Paying Agent is unable to apply any money in accordance with
Section 13.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to Section 13.01 until such time as the Paying Agent is permitted to apply all such money in accordance with
Section 13.02; provided, however, that if the Company makes any payment of interest on or principal of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the
Holders of such Notes to receive such payment from the money held by the Paying Agent.

 SECTION 14.07. No Security Interest Created. Nothing in this Indenture or in the Notes, expressed or implied, shall be

or claim under this Indenture. 
 SECTION 14.10. Authenticating Agent. The Agent shall appoint an authenticating agent (together with
its successors, assigns and validly appointed replacements, the “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 2.05, Section 2.06, Section 2.07, Section 2.08, Section 3.04 and Section 7.04
as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of
Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Agent” and a certificate of authentication executed on behalf of the Agent by an authenticating agent shall be deemed to satisfy any
requirement hereunder or in the Notes for the Agent’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant to Section 11.09. The Agent initially
appoints Citibank, N.A. as Authenticating Agent. 
 Any corporation or other entity into which any authenticating agent may be merged or

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, the Agent and to the Company. The Agent 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 Agent may appoint a successor authenticating agent, shall give written notice of such appointment to the Company and shall
mail notice of such appointment to all Noteholders 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 11.02, Section 11.03, Section 11.04, Section 12.03 and this
Section 14.10 shall be applicable to any authenticating agent. 
 SECTION 14.11. Calculations. Except as otherwise

shall provide a schedule of its calculations to each of the Trustee, the Agent and the Conversion Agent (if different than the Trustee), and each of the Trustee, the Agent and Conversion Agent (if different than the Trustee) is entitled to rely
conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee or the Paying Agent 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.

rules for action by, or a meeting of, Holders. The Note Registrar and the Paying Agent may make reasonable rules for their functions.

original, but such counterparts shall together constitute but one and the same instrument. 

  
 92 








 SECTION 14.15. 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 14.16. No Recourse Against Others. No director, officer, employee, stockholder, incorporator or agent of the Company will have
any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such
liability. 
 SECTION 14.17. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 

SECTION 14.18. Force Majeure. In no event shall the Trustee or the Agent 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 and the Agent shall use reasonable efforts that

ARTICLE 15 
 REDEMPTION

 SECTION 15.01. Right to Redeem. The Notes shall not be redeemable before October 15, 2016, and no sinking fund is
provided for the Notes. On or after such date, the Company shall be entitled to redeem the Notes at its option, in whole or in part, provided that the last reported sale price of the Company’s common stock for at least 20 trading days (whether
or not consecutive) during the period of 30 consecutive trading days ending within 10 trading days immediately prior to the date of the Redemption Notice exceeds 130% of the applicable Conversion Price for the Notes on each applicable trading day.
The redemption price for the Notes to be redeemed on any Redemption Date (the “Redemption Price”) will equal (a) 100% of the principal amount of the Notes being redeemed plus (b) accrued and unpaid interest (including
additional interest), if any, to, but excluding, the Redemption Date, unless the Redemption Date falls after a record date but on or prior to the immediately succeeding interest payment date, in which case the Company shall instead pay the full
amount of accrued and unpaid interest, including any additional interest, to the Holder of record as of the close of business on such record date. If Notes are redeemed on a date that is after a Regular Record Date for


  
 93 








 
the payment of interest and on or prior to the corresponding Interest Payment Date, accrued and unpaid interest will not be paid to the Holder of Notes being redeemed, and instead the full amount
of the relevant interest payment will be paid on such interest payment date to the Holder of record on such Regular Record Date. 
 SECTION
15.02. Notices to Paying Agent. If the Company elects to redeem Notes pursuant to the optional redemption provisions of the Notes, it shall notify the Paying Agent in writing of the Redemption Date, the principal amount of Notes to be
redeemed and the paragraph of the Notes pursuant to which the redemption will occur. 
 The Company shall give each notice to the Paying
Agent provided for in this Section at least 30 days before the Redemption Date unless the Paying Agent consents to a shorter period; provided, however, that if the Company mails a Redemption Notice to Holders more than 30 days
prior to the Redemption Date, in accordance with Section 15.05 hereto, the Company shall immediately give notice to the Paying Agent. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the
Company to the effect that such redemption will comply with the conditions herein. 
 SECTION 15.03. Selection of Notes to Be
Redeemed. In the event that the Company chooses to redeem less than all of the Notes at any time, selection of the Notes for redemption shall be made by the Paying Agent by lot or by such method as the Paying Agent shall deem fair and
appropriate in accordance with DTC procedures. The Paying Agent shall make the selection from outstanding Notes not previously called for redemption. Notes and portions of them the Paying Agent selects shall be in principal amounts of $1,000 or
multiples of $1,000. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Paying Agent shall notify the Company promptly of the Notes or portions of Notes to be redeemed.

 SECTION 15.04. Notice of Redemption. At least 30 days but not more than 60 days before a date for redemption of Notes, the Company
shall mail a notice of redemption (a “Redemption Notice”) by first-class mail to each Holder of Notes to be redeemed at such Holder’s registered address, except that Redemption Notices may be mailed more than 60 days prior to
the Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. Any inadvertent defect in the Redemption Notice, including an inadvertent failure to give notice, to any
Holder selected for redemption shall not impair or affect the validity of the redemption of any other Note redeemed in accordance with provisions of this Indenture. Simultaneously with providing such Redemption Notice, the Company shall issue a
press release or publish a notice containing the information included therein or shall publish such information on the Company’s website or through such other public medium as the Company may use at such time. 

The notice shall identify the Notes to be redeemed and shall state: 

(i) the Redemption Date; 

  
 94 








 (ii) the Redemption Price; 

(iii) the name and address of the Paying Agent; 

(iv) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price; 

(v) if fewer than all the outstanding Notes are to be redeemed, the identification and principal amounts of the particular
Notes to be redeemed; 
 (vi) that, unless the Company defaults in making such redemption payment, interest on Notes (or
portion thereof) called for redemption ceases to accrue on and after the Redemption Date; 
 (vii) the “CUSIP”
number, ISIN or “Common Code” number, if any, printed on the Notes being redeemed; 
 (viii) that no representation
is made as to the correctness or accuracy of the “CUSIP” number, ISIN, or “Common Code” number, if any, listed in such notice or printed on the Notes; 

(ix) that such Holder has a right to convert the Notes called for redemption upon satisfaction of the requirements therefor set
in the Indenture, and the conversion rate applicable to such conversion; and 
 (x) the time at which such Holders’
right to convert the Notes called for redemption will expire, which will be the close of business on the Business Day immediately preceding the Redemption Date. 

At the Company’s request, the Paying Agent shall give the Redemption Notice in the Company’s name and at the Company’s expense.
In such event, the Company shall provide the Paying Agent with the information required by this Section. 
 SECTION 15.05. Effect of
Redemption Notice. Once a Redemption Notice is mailed, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the Redemption Notice. Upon surrender to the Paying Agent, such Notes shall be
paid at the Redemption Price stated in the Redemption Notice, plus accrued interest to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment date), and such
Notes shall be canceled by the Paying Agent. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder. 

SECTION 15.06. Deposit of Redemption Price. Prior to the Redemption Date, the Company shall deposit with the Paying Agent (or, if the
Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of and accrued interest on all Notes to be redeemed on that date other than Notes or portions of Notes called for redemption
which have been delivered by the Company to the Paying Agent for cancellation. 

  
 95 








 SECTION 15.07. Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part,
the Company shall execute and the Authenticating Agent shall authenticate for the Holder (at the Company’s expense) a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 

SECTION 15.08. Effect of Redemptions in Part. In the event of any redemption in part, the Company shall not be required to
(i) issue, register the transfer of or exchange any notes during a period beginning at the open of business 15 days before the mailing of a Redemption Notice and ending at the close of business on the earliest date on which the relevant
Redemption Notice is deemed to have been given to all Holders of Notes to be redeemed or (ii) register the transfer of or exchange any Notes so selected for redemption, in whole or in part, except the unredeemed portion of any Notes being
redeemed in part. 
 SECTION 15.09. Conditions to Redemption. No Notes may be redeemed if the principal amount of the Notes has been
accelerated, 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 us in the payment of the applicable Redemption Price with respect to such Notes).

 CUSIP No. 63934E AP3 

Navistar International Corporation, a Delaware corporation (herein called the “Company”, which term includes any successor
Person under the Indenture hereinafter referred to), for value received, hereby promises to pay CEDE & CO., or registered assigns,
[                    ] DOLLARS ($[        ]) (or such greater or lesser principal amount as shall be
specified in the “Schedule of Exchanges of Securities” attached hereto) on October 15, 2018 unless earlier converted or repurchased, and to pay interest thereon as set forth in the manner, at the rates and to the Persons set forth in
the Indenture. 
 This Note shall bear interest at a rate of 4.50% per annum from October 11, 2013 or from the most recent date to
which interest had been paid or provided to, but excluding, the next scheduled Interest Payment Date, until the principal hereof shall be repaid. Interest on this Note will be computed on the basis of a 360-day year composed of twelve 30-day months.
Interest is payable semi-annually in arrears on each April 15 and October 15, commencing on April 15, 2014, to the Person in whose name this Note (or one or more predecessor securities) is registered at the close of business on the
Regular Record Date for such interest. Additional Interest will be payable at the option of the Company on the terms set forth in Section 5.02 of the within-mentioned Indenture. 

The Company will pay interest on overdue principal, and, to the extent lawful, on overdue interest, in each case at a rate of 4.50% per
annum. Interest not paid when due and any interest on principal or interest not paid when due will be paid to Holders on a special record date, which will be the 15th day preceding the date fixed by the Company for the payment of such interest,
whether or not such day is a Business Day. At least 15 days before a special record date, the Company will send to each Holder and to the Paying Agent a notice that sets forth the special record date, the payment date and the amount of interest to
be paid.

funds to the Depositary or its nominee, as the case may be, as the registered Holder of such Note. The Company shall pay principal of any Notes (other than Notes that are Global Notes) at the office or agency designated by the Company for that
purpose. The Company has initially designated Citibank, N.A. as its Paying Agent and Note Registrar in respect of the Notes and its agency in New York, New York as a place where Notes may be presented for payment or for registration of transfer. The
Company may, however, change the Paying Agent or Note Registrar for the Notes without prior notice to the Holders thereof, and the Company may act as Paying Agent or Note Registrar. Interest on the Notes (other than


  
 A-3

 [FORM OF REVERSE OF GLOBAL NOTE] 

NAVISTAR INTERNATIONAL CORPORATION 

4.50% Senior Subordinated Convertible Note due 2018 

This Note is one of a duly authorized issue of Securities of the Company (herein called the “Notes”), issued under and
pursuant to an Indenture dated as of October 11, 2013 (herein called the “Original Indenture”) by and among the Company, Wilmington Trust, National Association, herein called the “Trustee” and Citibank, N.A.,
as Note Registrar, Paying Agent, Transfer Agent, Authenticating Agent and Conversion Agent (the “Agent”), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee, the Note Registrar, the Paying Agent, the Transfer Agent, the Authenticating Agent, the Conversion Agent and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and
delivered. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. 

This Note is not subject to redemption at the option of the Company prior to October 15, 2016. 

As provided in and subject to the provisions of 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 all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Purchase Date at a price equal to the
Fundamental Change Purchase Price. 
 Except as described below, the Notes shall not be redeemable before October 15, 2016, and no
sinking fund is provided for the Notes. On or after such date, the Company shall be entitled to redeem the Notes at its option, in whole or in part, provided that the last reported sale price of the Company’s common stock for at least 20
trading days (whether or not consecutive) during the period of 30 consecutive trading days ending within 10 trading days immediately prior to the date of the Redemption Notice exceeds 130% of the applicable conversion price for the notes on each
applicable trading day. The Redemption Price for the Notes to be redeemed on any Redemption Date will equal (a) 100% of the principal amount of the Notes being redeemed plus (b) accrued and unpaid interest (including additional interest),
if any, to, but excluding, the Redemption Date, unless the Redemption Date falls after a record date but on or prior to the immediately succeeding interest payment date, in which case we will instead pay the full amount of accrued and unpaid
interest, including any additional interest, to the Holder of record as of the close of business on such record date. If Notes are redeemed on a date that is after a Regular Record Date for the payment of interest and on or prior to the
corresponding Interest Payment Date, accrued and unpaid interest will not be paid to the Holder of Notes being redeemed, and instead the full amount of the relevant interest payment will be paid on such interest payment date to the Holder of record
on such Regular Record Date. 

  
 A-7 








 Notice will be given not less than 30 nor more than 60 days prior to the Redemption Date, and
such notice will state, among other things: (a) that such Holder has a right to convert the Notes called for redemption upon satisfaction of the requirements therefor set forth in the Indenture, and the conversion rate applicable to such
conversion; and (b) the time at which such Holder’s right to convert the Notes called for redemption will expire, which will be the close of business on the Business Day immediately preceding the Redemption Date. Any inadvertent defect in
the Redemption Notice, including an inadvertent failure to give notice, to any Holder selected for redemption will not impair or affect the validity of the redemption of any other Note redeemed in accordance with provisions of the Indenture. 

As provided in and subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon
the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding October 15, 2018, to convert this Note or a portion thereof that is $1,000 or an integral
multiple thereof, into cash, shares of Common Stock or a combination thereof, at the Company’s discretion, at the applicable Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 

As provided in and subject to the provisions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental
Change Purchase Price and the principal amount of the Notes on the Stated Maturity thereof, as the case may be, to the holder who surrenders a Note to the Paying Agent to collect such payments in respect of the Note. The Company will pay cash
amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 
 The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes to be effected under the Indenture at any time by the Company,
the Agent and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes
at the time outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Note. 
 As provided in and subject to the provisions of 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 due and payable, by either the Trustee or Holders of not less than 25% in aggregate principal amount of Notes then
outstanding, and upon said declaration shall become due and payable, in the manner, with 

  
 A-8 








 
the effect and subject to the conditions provided in the Indenture; provided that upon the occurrence of an Event of Default specified in clauses (i) and (j) of
Section 5.01 of the Indenture, the principal amount of, and interest on, all the Notes shall automatically become due and payable. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and any premium and interest on this Note at the time, place and rate, and in the coin and currency, herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Note
Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer
in form satisfactory to the Company and the Note Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Notes are issuable only in registered
form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes and of
like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for
any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Note for registration of transfer, the Company, the Agent, the Trustee and any agent of the Company or
Trustee may treat the Person in whose name the Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Agent, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 All defined terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the
Indenture.
