 (2) an accounting term not otherwise defined has the meaning assigned to it and shall be construed in accordance with GAAP; 
 (3) “or” is not exclusive; 
 (4) “including,”
“includes” and “include” shall be deemed to be followed by the words “without limitation”; 
 (5) the words “herein”, “hereof” and “hereunder” and other words of similar import refer to this Indenture as a whole and not to any particular Article,
Section or other subdivision; 
 (6) unless the context otherwise requires, any reference to an “Article,” a
“Section” or an “Exhibit” refers to an Article, a Section or an Exhibit, as the case may be, of this Indenture; 
 (7) words in the singular include the plural, and words in the plural include the singular; 
 (8) all references to $, dollars, cash payments or money refer to United States currency; and 
 (9) unless the context requires otherwise, all references to payments of interest on the Notes shall include Additional Interest, if any, payable in accordance with the terms of Sections 5.02 or 7.01, as

 Section 1.04. Acts of Holders. Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except
as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee or to the Company, as applicable. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the 

  
 10 









 
“Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose
of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 1.04. 
 (a) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer

 (b) Any request, demand, authorization,
direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in

Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the
Close of Business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 
 ARTICLE 2 
 THE NOTES 

Section 2.01. Designation and Amount. The Notes shall be designated as the “4.25% Convertible Senior Notes due
2019.” The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is initially limited to $201,250,000, subject to Section 2.14 and except for Notes authenticated and delivered upon registration or
transfer of, or in exchange for, or in lieu of other Notes to the extent expressly permitted hereunder. 

  
 11 









 Section 2.02. Form and Dating. The Notes and the Trustee’s certificate of
authentication shall be substantially in the form of Exhibit A, which is a part of this Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions
and to be bound thereby. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage (provided that any such notation, legend or endorsement required by usage is in a form acceptable to the Company).
The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Note shall be dated the date of its authentication. Except as otherwise expressly permitted in this Indenture, all Notes shall be identical in all
respects. Notwithstanding any differences among them, all Notes issued under this Indenture shall vote and consent together on all matters as one class. 
 (a) Initial Notes. The Notes initially shall be issued in the form of one Global Note that shall be deposited with the Trustee at its Corporate Trust Office or such other address as the Trustee may
designate from time to time by notice to the Holders and the Company, as custodian for the Depositary and registered in the name of DTC or the nominee thereof (DTC, or any successor thereto, being hereinafter referred to as the
“Depositary”), duly executed by the Company and authenticated by the Trustee as hereinafter provided. 
 (b)
Global Notes in General. Each Global Note shall represent the outstanding Notes as shall be specified therein and each Global Note shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time
endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, purchases by the Company and conversions. 

Any adjustment of the aggregate principal amount of a Global Note to reflect the amount of any increase or decrease in the amount of
outstanding Notes represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 hereof and shall be made on the records of the Trustee and the Depositary. Payment of the
principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price on the Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders
eligible to receive payment is provided for herein. 
 (c) Book-Entry Provisions. This Section 2.02(c) shall apply
only to Global Notes deposited with or on behalf of the Depositary. The Company shall execute and the Trustee shall, in accordance with Section 2.03, authenticate and deliver Global Notes that (i) shall be registered in the name of the
Depository or the nominee of the Depositary and (ii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions. 
 (d) Legends. Each Global Note shall bear the Global Securities Legend set forth in Exhibit A unless otherwise directed by the Company. 

Section 2.03. Execution and Authentication. The Notes shall be executed on behalf of the Company by any Officer. The
signature of the Officer on the Notes may be manual or facsimile. 

  
 12 









 If an Officer whose signature is on a Note no longer holds that office at the time the
Trustee authenticates the Note, the Note shall be valid nevertheless. 
 At any time after the Original Issuance Date, the
Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee, in accordance with such Company Order, shall authenticate and
deliver such Notes. 
 A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of
authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Notes shall originally be issued only in registered form without coupons and only in denominations of $1,000 of principal amount and any integral multiple thereof. 

The Trustee may appoint authenticating agents. The Trustee may at any time after the Original Issuance Date appoint an authenticating
agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so, except any Notes issued pursuant to Section 2.07 hereof. Each reference in this Indenture to authentication by
the Trustee includes authentication by such agent. An authenticating agent shall have the same right to deal with the Company as the Trustee with respect to such matters for which it has been appointed. 

Section 2.04. Registrar, Paying Agent and Conversion Agent. The Company shall maintain in the Borough of Manhattan, New York
City an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”), an office or agency in where Notes may be presented for payment (“Paying Agent”), an office or agency
where Notes may be presented for conversion (“Conversion Agent”) and an office or agency where notices to or upon the Company in respect of the Notes and this Indenture may be served. The Registrar shall keep a register for the
recordation of, and shall record, the names and addresses of Holders of the Notes, the Notes held by each Holder and the transfer, exchange and conversion of Notes (the “Register”). The entries in the Register shall be conclusive,
and the parties may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Holder hereunder for all purposes of this Indenture. The Company may have one or more co-registrars, one or more additional paying agents
and one or more additional conversion agents. The term Paying Agent includes any such additional paying agents. The term Conversion Agent includes any such additional conversion agents. 

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent, Conversion Agent or co-registrar not a
party to this Indenture, which (i) shall implement the provisions of this Indenture relating to such agent and (ii) in the case of the Paying Agent, shall include the provisions set forth in Section 5.05. The Company shall promptly
notify the Trustee of the name and address of any such agent, and of any change therein. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, any presentations, surrenders, notices and demands required to be made by, or at
the office of, any such agent may be made or served at the Corporate Trust Office or in accordance with Section 14.01; provided that the Trustee shall be entitled to appropriate compensation therefor pursuant to Section 8.06. The
Company may act as Paying Agent, Registrar, Conversion Agent or co-registrar. 

  
 13 









 The Company initially appoints the Trustee as the Paying Agent, the Conversion Agent, and
the Registrar, in connection with the Notes, and the Corporate Trust Office to be such office or agency of the Company for the aforesaid purposes. The Company may at any time rescind the designation of the Paying Agent, Conversion Agent or the
Registrar or approve a change in the location through which any of them acts; provided that the Paying Agent, Conversion Agent and Registrar must be located within the Borough of Manhattan, New York City. 

Section 2.05. Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, promptly after each Record Date, and at such other times as the Trustee may request in writing, a list in such form
and as of such date as the Trustee may reasonably require of the names and addresses of Holders. 
 Section 2.06.
Transfer and Exchange.  
 (a) Subject to Section 2.12 hereof, upon surrender for registration of transfer of any Note,
together with a written instrument of transfer satisfactory to the Registrar duly executed by the Holder or such Holder’s attorney-in-fact duly authorized in writing, at the office or agency of the Company-designated Registrar or co-Registrar
pursuant to Section 2.04, (i) the Company shall execute, and the Trustee (or any authenticating agent) shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized
denomination or denominations, of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture and (ii) the Registrar shall record the information required pursuant to Section 2.04 regarding
the designated transferee or transferees in the Register. No service charge shall be imposed by the Company, the Trustee, the Registrar, any co- Registrar or the Paying Agent for any registration of transfer or exchange of Notes, but the Company may
require a Holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being
different from the name of the Holder of the old Notes surrendered for registration of transfer or exchange. 
 At the option of
the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations, of a like aggregate principal amount, upon surrender of the Notes to be exchanged, at such office or agency, together with a written instrument of
transfer satisfactory to the Registrar duly executed by the Holder or such Holder’s attorney-in-fact duly authorized in writing, and documents of identity and title satisfactory to the Registrar. Whenever any Notes are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 

The Company shall not be required to make, and the Registrar need not register, transfers or exchanges of any Note (x) surrendered
for conversion, (y) in respect of which a Fundamental Change Purchase Notice has been given and not validly withdrawn by the Holder thereof in accordance with the terms of this Indenture or (z) selected for Optional Redemption in


  
 14 









 
accordance with Article 4, in the case of an Optional Redemption of less than all of the Notes (except, in the case of a Note to be converted, purchased or redeemed in part by the Company, the
portion of such Note not to be so converted, purchased or redeemed). 
 (b) Notwithstanding any provision to the contrary
herein, so long as a Global Note remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Note, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers of
a Global Note shall be limited to transfers of such Global Note to the Depositary, to nominees of the Depositary or to a successor of the Depositary or such successor’s nominee. 

(c) Successive registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each
such registration shall be noted on the Register. 
 (d) Any Registrar appointed pursuant to Section 2.04 shall provide to
the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Notes upon transfer or exchange of Notes. 
 (e) Transfer Restrictions. 
 (i) Every Note that bears or is
required under this Section 2.06(e) to bear the Restricted Securities Legend (the “Restricted Notes”) shall be subject to the restrictions on transfer set forth in this Section 2.06(e) and such legend unless such
restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Note, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. If a
request is made to remove the Restricted Securities Legend from any Restricted Note prior to the Resale Restriction Termination Date, the legend shall not be removed unless there is delivered to the Company and the Registrar such certificates, legal
opinions and other information as they may reasonably require confirming that such Notes, upon such transfer, will not be “restricted” within the meaning of Rule 144. In such a case, upon (1) provision of such certificates, legal
opinions and/or other information, or (2) notification by the Company to the Trustee and Registrar of the sale of such Note pursuant to a registration statement that is effective at the time of such sale, the Trustee, pursuant to a Company
Order, shall authenticate and deliver a Note that does not bear the Restricted Securities Legend. 
 (ii) Except
as provided elsewhere in this Indenture, until the later of (x) the date that is one year after the Original Issuance Date or such shorter period of time as permitted by Rule 144 or any successor provision thereto and (y) such other date
as may be required by applicable law (such date the “Resale Restriction Termination Date”), any certificate evidencing such Notes (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if
any, issued upon conversion thereof, which shall bear the Restricted Stock Legend, if applicable) shall bear the Restricted Securities Legend unless (I) such Notes have been transferred (1) under a registration statement that has been
declared effective under the Securities Act, or (2) in accordance with Rule 144, or (II) such requirement is waived by the Company. 

  
 15 









 (iii) No transfer of any Restricted Note will be registered by the Registrar
unless the applicable box on the Form of Transfer Certificate attached to such Restricted Note has been checked and such certificates, legal opinions and other information as reasonably required by the Registrar or Company confirming that the
applicable condition to transfer has been satisfied have been provided. 
 (f) Legends on the Common Stock. Except as
provided elsewhere in this Indenture (including, without limitation, Section 2.06(i) below), until the later of (x) the Scheduled Free Trade Date and (y) the date that is three months after the holder of such shares of Common Stock
ceases to be an Affiliate of the Company (if applicable), any stock certificate representing shares of the Common Stock issued upon conversion of any Notes shall bear the Restricted Stock Legend unless (I) such Notes or such Common Stock, as
applicable, has been transferred (i) under a registration statement that has been declared effective under the Securities Act; or (ii) in accordance with Rule 144 under the Securities Act or (II) such requirement is waived by the
Company. 
 (g) The Company shall not permit any of its Affiliates to sell any Note or Common Stock issued upon the conversion
of a Note, unless upon such resale such security will no longer be a “restricted security” (as defined in Rule 144 under the Securities Act). If the Restricted Securities Legend is removed from the face of a Note and the Note is
subsequently held by an Affiliate of the Company, the Restricted Securities Legend shall be reinstated. 
 (h) 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 Registrar in accordance with the provisions of
this Section 2.06, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restricted Securities Legend and shall not be assigned a restricted CUSIP number. The Company shall be entitled to
instruct the custodian for the Depositary (or its nominee) in writing to so surrender any Global Note as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, such
custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the Restricted Securities Legend and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the
Trustee upon the occurrence of the Scheduled Free Trade Date and promptly after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

 (i) Upon the removal of such Restricted Stock Legend, the Company shall (i) notify the holders of any such shares that
such Restricted Stock Legend has been removed; (ii) notify the transfer agent for the Common Stock to change the CUSIP number for any such shares to the applicable unrestricted CUSIP number, if such shares are in certificated form, and
(iii) if such shares are in global form, comply with Applicable Procedures regarding such de-legending and the change from a restricted to unrestricted CUSIP number. Any shares of Common Stock delivered upon the conversion of any Note to any
Person that is not, and for at least three months has not been, an Affiliate of the Company shall be issued without any Restricted Stock Legend if (x) such conversion occurs after the Scheduled Free Trade Date or (y) such Note otherwise
does not, or would not be required hereunder to, bear the Restricted Securities Legend. 

  
 16 









 
Notwithstanding anything in this Indenture or the Notes to the contrary, any Person, other than an Affiliate of the Company, who holds shares of Common Stock that were issued upon conversion
shall have the right to enforce this Section 2.06(i) notwithstanding that such Person is not a Holder of Notes. 

Section 2.07. Replacement Notes. If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that
such Note has been lost, destroyed or stolen and the Holder provides evidence of the loss, theft or destruction reasonably satisfactory to the Company and the Trustee, the Company shall issue, and the Trustee shall authenticate, a replacement Note
if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond
reasonably sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss that any of them may suffer if a Note is replaced. The Company and the
Trustee may charge the Holder for their expenses in replacing a Note. 
 Upon the issuance of any new Notes under this
Section 2.07, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith. 
 Every new Note issued pursuant to this Section 2.07 in exchange for any mutilated Note, or in lieu of any
destroyed, lost or stolen Note, shall constitute an original additional contractual obligation of the Company and any other obligor upon the Notes, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by
anyone, and shall be entitled to all benefits of (and shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. 

Section 2.08. Outstanding Notes. Notes outstanding at any time include and are limited to all Notes authenticated by the
Trustee except (i) Notes cancelled by the Trustee or required to be delivered to the Trustee for cancellation in accordance with Section 2.10, (ii) Notes, or portions thereof, the principal of which has become due and payable on the
Maturity Date, on a Fundamental Change Purchase Date or otherwise, and in respect of which monies in the necessary amount shall have been deposited in trust with the Trustee or with any Paying Agent (other than the Company) or shall have been set
aside and segregated in trust by the Company (if the Company shall act as its own Paying Agent), (iii) Notes, or portions thereof, that have been converted pursuant to Article 11 and that are required to be cancelled pursuant to
Section 2.10 and (iv) Notes repurchased by the Company, directly or indirectly, whether by the Company or its Subsidiaries, pursuant to Section 2.14 (other than Notes repurchased pursuant to cash-settled swaps or other derivatives).
For the purpose of determining whether the Holders of the requisite principal amount of Notes have given or concurred in any request, demand, authorization, direction, notice, consent, waiver or other action hereunder (including, without limitation,
determinations pursuant to Articles 7 and 10) only outstanding Notes shall be considered in any such determination. In addition, for the purpose of any such determination, Notes that are owned by the Company, by any Subsidiary thereof or by any
Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such

determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a
Trust Officer knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 2.08 if the pledgee shall establish to the satisfaction of the Trustee
the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company
or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly
an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 8.01, the Trustee shall be entitled to accept
such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

Section 2.09. Temporary Notes. Until Certificated Notes are ready for delivery, the Company may execute and the Trustee or an
authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed) (“Temporary Notes”). Temporary Notes shall be issuable in any authorized
denomination, and substantially in the form of Certificated Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such Temporary Note shall be executed by
the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Certificated Notes. Without unreasonable delay the Company will prepare,
execute and deliver to the Trustee or such authenticating agent Certificated Notes (other than any Global Note) and thereupon any or all Temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency
maintained by the Company pursuant to Section 2.04 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such Temporary Notes an equal aggregate principal amount of Certificated Notes. Such exchange shall
be made by the Company at its own expense and without any charge therefor. Until so exchanged, the Temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Certificated Notes
authenticated and delivered hereunder. 
 Section 2.10. Cancellation. The Company shall cause all Notes surrendered
for the purpose of payment, repurchase (including pursuant to Section 3.01 or Section 2.14, other than Notes repurchased pursuant to cash-settled swaps or other derivatives), redemption, registration of transfer or exchange or conversion,
if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by it, and
no Notes shall be authenticated in exchange therefor except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall
deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order.

 Section 2.11. Persons Deemed Owners. Prior to due presentment of a Note for
registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered in the Register as the owner of such Note for the purpose of receiving payment of principal,
interest, if any, or payment of the Fundamental Change Purchase Price, for the purpose of conversion and for all other purposes whatsoever, subject to Section 2.06(i), Section 2.08 and Section 2.12(a)(ii), whether or not such Note be
overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 Section 2.12. Transfer of Notes.  
 (a) Notwithstanding any other
provisions of this Indenture or the Notes, (A) any transfer of a Global Note, in whole or in part, shall be made only in accordance with Sections 2.06 and 2.12(a)(i); and (B) any exchange of a beneficial interest in a Global Note for a
Certificated Note shall comply with Sections 2.06 and 2.12(a)(ii). All such transfers and exchanges shall comply with the Applicable Procedures to the extent so required. 

(i) Transfer of Global Note. A Global Note may not be transferred, in whole or in part, to any Person other than
the Depositary or a nominee or any successor thereof, and no transfer of a Global Note to any other Person may be registered; provided that this clause (i) shall not prohibit any transfer of a Note that is issued in exchange for a Global
Note but is not itself a Global Note. No transfer of a Note to any Person shall be effective under this Indenture or the Notes unless and until such Note has been registered in the name of such Person. Nothing in this Section 2.12(a)(i) shall
prohibit or render ineffective any transfer of a beneficial interest in a Global Note effected in accordance with the other provisions of this Section 2.12(a). 

(ii) Restrictions on Exchange of a Beneficial Interest in a Global Note for a Certificated Note. 

(A) A Certificated Note will be issued and delivered: 

(1) To each person that DTC identifies as a beneficial owner of the related Notes only if (a) DTC notifies the
Company that it is unwilling or unable to continue as Depositary for the Global Notes and a successor Depositary is not appointed by the Company within 90 days of such notice; or (b) DTC ceases to be registered as a clearing agency under the
Exchange Act and a successor Depositary is not appointed by the Company within 90 days of such cessation; or 

(2) if an Event of Default has occurred and is continuing, to each beneficial owner who requests that its beneficial
interests in the Notes be exchanged for Certificated Notes. 
 Notwithstanding anything to the contrary in this Indenture or in
the Notes, following the occurrence and during the continuance of an Event of Default, any beneficial owner of 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 beneficial owner’s right to exchange its beneficial interest in such Global Note for a Certificated Note in accordance with this Section 2.12(a)(ii). 

  
 19 









 In connection with the exchange of an entire Global Note for Certificated Notes pursuant to
this Section 2.12(a)(ii), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and upon Company Order the Trustee shall authenticate and deliver, to each beneficial owner identified
by DTC in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Certificated Notes of authorized denominations. 
 (B) Upon receipt by the Registrar of instructions from the Holder of a Global Note directing the Registrar to (x) issue one or more Certificated Notes in the amounts specified to the owner of a
beneficial interest in such Global Note and (y) debit or cause to be debited an equivalent amount of beneficial interest in such Global Note, subject to the Applicable Procedures: 

(1) the Registrar shall notify the Company and the Trustee of such instructions and identify the owner of and the amount
of such beneficial interest in such Global Note; 
 (2) the Company shall promptly execute, and upon Company
Order, the Trustee shall authenticate and deliver, to such beneficial owner Certificated Note(s) in an equivalent amount to such beneficial interest in such Global Note; and 

(3) the Registrar shall decrease such Global Note by such amount in accordance with the foregoing. 

(iii) Restrictions on Transfer of a Certificated Note for a Beneficial Interest in a Global Note. A Certificated
Note may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below. 
 Upon receipt by the Trustee of a Certificated Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with written instructions directing
the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Note to reflect an increase in the aggregate principal amount of the Notes represented by the Global Note, such instructions
to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Note and cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures
existing between the Depositary and the Registrar, the aggregate principal amount of Notes represented by the Global Note to be increased by the aggregate principal amount of the Certificated Note to be exchanged, and shall credit or cause to be
credited to the account of the Person specified in such instructions a beneficial interest in the Global Note equal to the principal amount of the Certificated Note so cancelled. If no Global Notes are then outstanding, the Company shall issue and
the Trustee shall authenticate, upon written order of the Company in the form of an Officer’s Certificate, a new Global Note in the appropriate principal amount. 

  
 20 









 (b) None of the Trustee, the Paying Agent, the Registrar or the Conversion Agent shall have
any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between
or among DTC participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the
terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 (c) None of the Trustee, the Paying Agent, the Registrar or the Conversion Agent shall have any responsibility or obligation to any beneficial owner in a Global Note, an DTC participant or other Person
with respect to the accuracy of the records of DTC or its nominee or of any DTC participant, with respect to any ownership interest in the Notes or with respect to the delivery to any DTC participant, beneficial owner or other Person (other than
DTC) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes and this
Indenture shall be given or made only to or upon the order of the registered Holders (which shall be DTC or its nominee in the case of the Global Note). The rights of beneficial owners in the Global Note shall be exercised only through DTC subject
to the Applicable Procedures, other than (i) the right of a beneficial owner to exchange its beneficial interest in a Global Note for a Certificate Note during the continuance of an Event of Default pursuant to Section 2.12(a)(ii) and
(ii) the right of a holder of Common Stock issued upon conversion to enforce the provisions of Section 2.06(i). The Trustee, the Paying Agent, the Registrar and the Conversion Agent shall be entitled to rely and shall be fully protected in
relying upon information furnished by DTC with respect to its members, participants and any beneficial owners. Subject to the exceptions set forth in the second preceding sentence, the Trustee, the Paying Agent, the Registrar and the Conversion
Agent shall be entitled to deal with DTC, and any nominee thereof, that is the registered Holder of any Global Note for all purposes of this Indenture relating to such Global Note (including the payment of principal and interest and the giving of
instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Note) as the sole holder of such Global Note and shall have no obligations to the beneficial owners thereof. None of the Trustee, the Paying
Agent, the Registrar or the Conversion Agent shall have any responsibility or liability for any acts or omissions of DTC with respect to such Global Note, for the records of any such Depositary, including records in respect of beneficial ownership
interests in respect of any such Global Note, for any transactions between the DTC and any DTC participant or between or among DTC, any such DTC participant and/or any holder or owner of a beneficial interest in such Global Note, or for any
transfers of beneficial interests in any such Global Note. 
 (d) Notwithstanding the foregoing, with respect to any Global
Note, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC (or its nominee), as a Holder, with respect to
such Global Note or shall impair, as between DTC and owners of beneficial interests in such Global Note, the operation of customary practices governing the exercise of the rights of DTC (or its nominee) as Holder of such Global Note. 

Section 2.13. CUSIP and ISIN Numbers.  

  
 21 









 (a) The Company, in issuing the Notes, shall use restricted CUSIP, ISIN or other similar
numbers for such Notes (if then generally in use) until such time as the Restricted Securities Legend is removed therefrom. At such time as the legend is removed from such Notes, the Company will use an unrestricted CUSIP number for such Note, but
only with respect to the Notes where so removed. The Company and the Trustee may use CUSIP, ISIN or other similar numbers in notices as a convenience to Holders; provided, however, that neither the Company nor the Trustee shall have
any responsibility for any defect in the CUSIP, ISIN or other similar number that appears on any Note, check, advice of payment or notice, and any such notice may state that no representation is made as to the correctness of such numbers either as
printed on the Notes or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Notes, and any action taken in connection with such a notice shall not be affected by any defect in or
omission of such numbers. The Company shall promptly notify the Trustee in the event of any change in the CUSIP, ISIN or other similar numbers. 
 (b) Until such time as the Restricted Stock Legend is no longer required to be borne by any shares of Common Stock issued upon the conversion of the Notes pursuant to Section 2.06(f) or otherwise,
any shares of Common Stock issued upon conversion of the Notes shall bear a restricted CUSIP number. At such time as the Restrictive Stock Legend is no longer required to be borne by any shares of Common Stock issued upon the conversion of the Notes
pursuant to Section 2.06(f) or otherwise, any shares of Common Stock issued upon conversion of the Notes shall bear an unrestricted CUSIP number. 
 Section 2.14. Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes with
the same terms as the Notes initially issued hereunder in an unlimited aggregate principal amount, provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes,
such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order and an Officer’s Certificate, which shall cover such matters, in addition to
those required by Section 14.03, as the Trustee shall reasonably request. In addition, upon the reasonable request of the Trustee, the Company shall furnish to the Trustee an Opinion of Counsel which shall cover such legal conclusions, in
addition to the matters required by Section 14.03, as the Trustee shall reasonably request. The Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company),
repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash settled swaps or other
derivatives. 
 ARTICLE 3

 If a Fundamental Change occurs at any time, each Holder shall have the right, at its option,
to require the Company to purchase for cash all or any portion of its Note equal in principal amount to $1,000 or an integral multiple of $1,000 in excess thereof, on a date (the “Fundamental Change Purchase Date”) specified by the
Company in the Fundamental Change Purchase Notice for such Fundamental Change and that is not less than 20 calendar days nor more than 35 calendar days immediately following the relevant Fundamental Change Notice Date, at a price (the
“Fundamental Change Purchase Price”) equal to 100% of the principal amount of the Note to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Purchase Date; provided, however,
that if the Fundamental Change Purchase Date occurs after a Record Date for the payment of interest, and on or prior to the corresponding Interest Payment Date, the Company shall pay the full amount of accrued and unpaid interest payable on such
Interest Payment Date to the Holder of record of such Note on such Record Date and the Fundamental Change Purchase Price shall instead be equal to 100% of the principal amount of such Note. 

Section 3.02. Fundamental Change Purchase Right Notice. On or before the 5th calendar day immediately following the
occurrence of a Fundamental Change, the Company shall deliver written notice of such Fundamental Change and the resulting purchase right (the “Fundamental Change Notice,” and the date of such mailing, the “Fundamental Change

terms of this Indenture; 
 (m) the procedures for withdrawing a Fundamental Change Purchase Notice; 

(n) that unless the Company defaults in making payment of such Fundamental Change Purchase Price on the Notes surrendered for purchase by
the Company, interest, if any, on Notes for which a Fundamental Change Purchase Notice has been validly given and not withdrawn will cease to accrue on and after the Fundamental Change Purchase Date; 

(o) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes; and 

(p) such other information as the Company reasonably determines is appropriate to include therein. 

Section 3.03. Fundamental Change Purchase Notice.  
 (a) To exercise its purchase right upon the occurrence of a Fundamental Change under Section 3.01, a Holder or beneficial owner of a Note, as the case may be, must (i) deliver, by the Close of
Business on the Business Day immediately preceding the Fundamental Change Purchase Date, the Notes to be purchased, duly endorsed for transfer, together with the duly completed “Form of Fundamental Change Purchase Notice” on the reverse
side of the Notes that such Holder is tendering for purchase (such notice, a “Fundamental Change Purchase Notice”) to the Paying Agent if the Notes that such Holder is delivering for purchase are Certificated Notes, or
(ii) comply with the Applicable Procedures if the Notes (or portions thereof) being delivered for purchase are Global Notes. The Fundamental Change Purchase Notice must state: 

(A) if the Notes being delivered for purchase are Certificated Notes, the certificate numbers of such Notes; 

(B) the portion of the principal amount of the Notes to be purchased, which portion must be $1,000 or an integral multiple

a validly endorsed and delivered Fundamental Change Purchase Notice, together with any Notes to which such Fundamental Change Purchase Notice pertains, in a form that conforms with the description contained in such Fundamental Change Purchase Notice
in all material aspects, the Holder submitting the Notes shall not be entitled to receive the Fundamental Change Purchase Price for such Notes. 

  
 24 









 (c) After delivering a Fundamental Change Purchase Notice to the Paying Agent, a Holder may
withdraw such Fundamental Change Purchase Notice (in whole or in part) by delivering to the Paying Agent a written notice of withdrawal at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change
Purchase Date. Such notice of withdrawal shall state: 
 (i) the principal amount of any Notes with respect to

 (iii) the principal amount, if any, which amount must equal $1,000 or an integral multiple thereof, that remains subject to the original Fundamental Change Purchase Notice. 

In the case of a Global Note, the beneficial owner of an interest therein who has surrendered such interest for repurchase pursuant to this Article 3
must comply with Applicable Procedures to withdraw such repurchase request. 
 Section 3.04. Effect of Fundamental
Change Purchase Notice.  
 (a) If a Holder validly delivers to the Paying Agent a Fundamental Change Purchase Notice
(together with all necessary endorsements) with respect to a Note, such Holder may no longer convert such Note unless and until such Holder validly withdraws such Fundamental Change Purchase Notice in accordance with Section 3.03(c) above.

 (b) Upon the Paying Agent’s receipt of (x) a valid Fundamental Change Purchase Notice (together with all necessary
endorsements) and (y) the Notes to which such Fundamental Change Purchase Notice pertains, the Holder of the Notes to which such Fundamental Change Purchase Notice pertains shall be entitled, except to the extent such Holder has validly

(ii) if the Notes are Certificated Notes, the date of delivery of such Notes to the Paying Agent, or, if the Notes are Global Notes, the date of book-entry transfer.

of all of the Notes for which the Holders thereof have tendered and not validly withdrawn a Fundamental Change Purchase Notice in accordance with Section 3.03 above: 

  
 25 









 (i) such Notes shall cease to be outstanding and interest shall cease to
accrue thereon (whether or not book-entry transfer of such Notes is made or whether or not such Notes are delivered to the Paying Agent, as the case may be); and 

(ii) all other rights of the Holders with respect to the tendered Notes shall terminate (other than the right to receive
payment of the Fundamental Change Purchase Price upon delivery or transfer of the Notes, and previously accrued and unpaid interest, if any). 
 Section 3.05. Deposit of Fundamental Change Purchase Price. Prior to 10:00 a.m., New York City time, on the Fundamental Change Purchase Date, the Company shall deposit with the Trustee or with
the Paying Agent (or, if the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 5.05(b)) an amount of cash (in immediately available funds if deposited on such Business Day), sufficient to pay the
aggregate Fundamental Change Purchase Price of all the Notes or portions thereof which are to be purchased as of the Fundamental Change Purchase Date. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the
Company), payment for Notes surrendered for purchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date) will be made on the later of (i) the Fundamental Change
Purchase Date (provided the Holder has satisfied the conditions in Section 3.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder
thereof in the manner required by Section 3.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Register; provided, however, that payments to the Depositary shall
be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. 

Section 3.06. Notes Purchased in Part. Any Certificated Note that is to be purchased only in part shall be surrendered at the
office of the Paying Agent (with, if the Company or the Trustee so requires, 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-in-fact duly authorized in writing) and the Company shall execute and the Trustee 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 which is not purchased, or in the case of a Global Note, the Company shall instruct the Registrar to decrease such
Global Note by the principal amount of the purchased portion of the Note surrendered. 
 Section 3.07. Covenant to
Comply with Securities Laws Upon Purchase of Notes. In connection with any offer to purchase Notes under this Article 3, the Company shall, if required, (a) comply with the provisions of the tender offer rules under the Exchange Act that
may then be applicable, (b) file a Schedule TO (or any successor thereto) or any other required schedule under the Exchange Act, and (c) otherwise comply with all applicable U.S. federal and state securities laws, in each case so as to
permit the rights and obligations under this Article 3 to be exercised in the time and in the manner specified herein. 

  
 26 









 Section 3.08. Repayment to the Company. To the extent that the aggregate amount
of cash deposited by the Company pursuant to Section 3.03 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof which the Company is obligated to purchase as of the Fundamental Change Purchase Date, then,
unless otherwise agreed in writing with the Company, promptly after the Business Day following the Fundamental Change Purchase Date, the Paying Agent shall, subject to Section 8.06, return any such excess to the Company. 

Section 3.09. Covenant Not to Purchase Notes Upon Certain Events of Default.  

(a) Notwithstanding anything to the contrary in this Article 3, the Company shall not purchase any Notes under this Article 3 if there
has occurred and is continuing an Event of Default with respect to the Notes, unless the payment by the Company of the Fundamental Change Purchase Price will cure such Event of Default. 

(b) If a Fundamental Change Purchase Notice is tendered and, on the Fundamental Change Purchase Date, such Fundamental Change Purchase
Notice has not been validly withdrawn in accordance with Section 3.03(c) above, and, pursuant to this Section 3.09, the Company is not permitted to purchase Notes, the Paying Agent will deem withdrawn such Fundamental Change Purchase
Notice. 
 (c) If a Holder tenders a Note for purchase pursuant to this Article 3 and, on the Fundamental Change Purchase Date,
pursuant to this Section 3.09, the Company is not permitted to purchase such Note, the Paying Agent will (i) if such Note is a Certificated Note, return such Note to such Holder, and (ii) if such Note is held in book-entry form, in
compliance with the Applicable Procedures, deem to be cancelled any instructions for book-entry transfer of such Note. 
 ARTICLE
4 
 OPTIONAL REDEMPTION 
 Section 4.01. Optional Redemption. No sinking fund is provided for the Notes. Prior to April 6, 2016, the Notes shall not be redeemable by the Company. On or after April 6, 2016, the
Company may redeem (an “Optional Redemption”) for cash all or part of the Notes, at its option. The Company shall provide notice as set forth in Section 4.02 and the redemption price shall be equal to 100% of the principal
amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (the “Redemption Price”) (unless the Redemption Date falls after a Record Date but on or prior to the
immediately succeeding Interest Payment Date, in which case the Company shall pay the full amount of accrued and unpaid interest to the Holder of record as of the Close of Business on such Record Date, and the Redemption Price shall be equal to 100%
of the principal amount of the Notes to be redeemed). 

  
 27 









 Section 4.02. Notice of Optional Redemption; Selection of Notes. 

(a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may be, any part of the Notes pursuant to
Section 4.01, it shall fix a date for redemption (each, a “Redemption Date”), which must be a Business Day, and it or, at its written request received by a Trust Officer of the Trustee at its Corporate Trust Office not less
than 60 calendar days prior to the Redemption Date (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall mail or cause to be mailed or deliver electronically a
notice of such Optional Redemption (a “Redemption Notice”) not less than 45 nor more than 60 calendar days prior to the Redemption Date to each Holder of Notes at its last address as the same appears on the Register;
provided, however, that if the Company shall give such notice, it shall also give written notice of the Redemption Date to the Trustee, the Paying Agent and the Conversion Agent. 

(b) The Redemption Notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or
not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Note. 
 (c) Each Redemption Notice shall specify: 

(i) the Redemption Date; 
 (ii) the Redemption Price; 
 (iii) that on the Redemption Date, the
Redemption Price will become due and payable upon all outstanding Notes or each Note selected for redemption, as the case may be, and, if applicable, that interest thereon shall cease to accrue on and after said date; 

(iv) the place or places where such Notes are to be surrendered for payment of the Redemption Price; 

(v) that Holders may surrender their Notes for conversion at any time prior to the Close of Business on the Business Day
immediately preceding the Redemption Date; 
 (vi) the procedures a converting Holder must follow to convert its
Notes and the Settlement Method (if applicable) and Specified Dollar Amount (if applicable) that will apply to any conversion during the applicable Redemption Period; 

(vii) the Conversion Rate and the Observation Period (if applicable) that will apply to any conversion during the
Redemption Period; 
 (viii) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes;

 (ix) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be
redeemed; and 

  
 28 









 (x) in the case of an Optional Redemption of less than all of the Notes
outstanding, that the Company will not be required to register the transfer of or exchange any Note selected for redemption (except the unredeemed portion of any Note being redeemed in part). 
 A Redemption Notice shall be irrevocable. 
 (d) If the Company redeems fewer than
all of the outstanding Notes, the Trustee shall select the Notes or portions thereof to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or by another method the Trustee considers to be fair and
appropriate, in accordance with Applicable Procedures (in the case of a Global Note). If any Note selected for partial redemption is submitted for conversion in part after such selection, to the extent that the converted portion exceeds the portion
selected for redemption, the portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be the portion selected for redemption. On the Redemption Date, if only a portion of any Note is redeemed, appropriate
adjustments will be made to reflect a decrease in the principal amount of such Note (in the case of a Global Note) or a new Note in principal amount equal to the unredeemed portion thereof shall be issued (in the case of a Certificated Note).

 Section 4.03. Payment of Notes Called for Redemption. 

(a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 4.02, the Notes shall become due and
payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid
and redeemed by the Company at the applicable Redemption Price.

 Section 4.04. Restrictions on
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
the Company in the payment of the Redemption Price with respect to such Notes).

the contrary. The Company shall make all payments of principal and interest on Global Notes in immediately available funds to the Depositary or its nominee, in accordance with Applicable Procedures. 

(b) The Company shall make any required interest payments, if any, to the Person in whose name each Note is registered at the Close of
Business on the Record Date for such interest payment. The principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price shall be considered paid on the applicable date due if on such date the Trustee or the
Paying Agent holds, in accordance with this Indenture, cash sufficient to pay all such amounts then due. 

Section 5.02. SEC and Other Reports.  
 (a) The Company shall file with the Trustee within 15 days after the same are required to be filed with the SEC, copies of any documents or reports that the Company is required to file with the SEC
pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Any such document or report that the Company files with the SEC via the SEC’s EDGAR system shall be
deemed to be filed with the Trustee for purposes of this Section 5.02(a) at the time such documents are filed via the EDGAR system. 
 (b) If, at any time during the period beginning on, and including, the date which is six months after the Original Issuance Date, the Company fails to timely file any report that the Company is required
to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (other than reports on Form 8-K), or the Notes are not otherwise freely tradeable by Holders other than the Company’s Affiliates (as a result of restrictions pursuant
to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes, which shall accrue at a rate of 0.50% per annum, from and including the later of the date six months after the
Original Issuance Date and the first date on which such failure to file exists or the Notes are not freely tradeable, as the case may be, until the earlier of (i) the Scheduled Free Trade Date and (ii) the date on which such failure to
file has been cured (if applicable) and the Notes are freely tradeable.

at a rate of 0.50% per annum, if, and for so long as, the Restricted Securities Legend on the Notes has not been removed, the Notes are assigned a restricted CUSIP or the Notes are not otherwise freely tradeable by Holders other than the
Company’s Affiliates (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), in each case, on or after the Scheduled Free Trade Date.

Interest that may be payable as a result of the Company’s election pursuant to Section 7.01. 
 (e) Additional
Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes. 
 (f) If the Company is required to pay Additional Interest to Holders pursuant to clause (b) or (c) above, the Company shall provide an Officer’s Certificate to the Trustee (and if the
Trustee is not the Paying Agent, to the Paying Agent) to that effect, which shall be delivered in accordance with Section 14.01 no later than three Business Days prior to the date on which any such Additional Interest is scheduled to be paid
and shall make explicit reference to this Indenture, the Notes and the Company. Such Officer’s Certificate shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct the Trustee (or, if the
Trustee is not the Paying Agent, to the Paying Agent) to make payment to the extent it receives funds from the Company to do so. Unless and until the Trustee receives such an Officer’s Certificate, subject to Article 8, the Trustee may assume
without inquiry that no such Additional Interest is payable. 
 (g) Delivery of any such reports, information and documents to
the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including
the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). 
 Section 5.03. Compliance Certificate. Within 120 days after the end of each fiscal year (beginning with the fiscal year ending December 31, 2013) of the Company, the Company shall deliver
to the Trustee at its Corporate Trust Office in accordance with Section 14.01, making specific reference to this Indenture, the Notes and the Company, an Officer’s Certificate indicating whether each signer thereof knows of any Default
that occurred during the previous year and, if so, shall specify each such Default and the nature and status thereof of which it may have knowledge and what action the Company is taking or proposes to take in respect thereof. 

Section 5.04. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 
 Section 5.05. Provisions as to Paying Agent. 

  
 31 









 (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will
cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.05: 

(i) that it will hold all sums held by it as such agent for the payment of the principal (including the Fundamental Change
Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes; 
 (ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including the Fundamental Change Purchase Price, if applicable) of, and accrued and
unpaid interest on, the Notes when the same shall be due and payable; and 
 (iii) that at any time during the
continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 
 The Company shall, on or before each due date of the principal (including the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying
Agent a sum sufficient to pay such principal (including the Fundamental Change Purchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure
to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 10:00 a.m., New York City time, on such date. 

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Fundamental
Change Purchase Price or Redemption Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the
Fundamental Change Purchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the
principal (including the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable. 
 (c) Anything in this Section 5.05 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason,
pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 5.05, such sums or amounts to be held by the Trustee upon the trusts herein contained and
upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal
(including the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Purchase Price, if


  
 32 









 
applicable) or interest has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published
once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, New York City, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 calendar days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 Section 5.06. Delivery of Certain Information. If, at any time, the Company is not subject to the reporting requirements of the Exchange Act, the Company shall, so long as any of the Notes or
any shares of Common Stock issuable upon conversion thereof will, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, upon the request of any Holder, beneficial owner or
prospective purchaser of the Notes or any shares of Common Stock issuable upon the conversion of Notes, promptly furnish to such Holder, beneficial owner or prospective purchaser the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act to facilitate the resale of the Notes or such shares of Common Stock pursuant to Rule 144A, as such rule may be amended from time to time. 
 ARTICLE 6 
 CONSOLIDATION, MERGER AND
SALE OF ASSETS 
 Section 6.01. Company May Consolidate, Merge or Sell Its
Assets on Certain Terms. The Company shall not consolidate with, merge with or into or enter into any similar transaction with, or convey, transfer or lease all or substantially all of its property and assets to, any Person unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”) is a corporation organized and validly
existing under the laws of the United States of America, any State thereof or the District of Columbia, and such Successor Company (if other than the Company) expressly assumes, by executing and delivering to the Trustee a supplemental indenture,
all of the Company’s obligations under the Notes and under this Indenture; 
 (b) if such transaction or event constitutes
a Share Exchange Event and the relevant Reference Property includes common stock or other securities issued by a third party, such third party fully and unconditionally guarantees all obligations of the Company or such Successor Company, as the case
may be, under the Notes and under this Indenture; 
 (c) immediately after giving effect to such transaction, no Default or
Event of Default has occurred or is continuing; and 

  
 33 









 (d) the Company and the Successor Company (if other than the Company) shall have delivered
to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that: 
 (i) each of (x) such
consolidation, merger (or similar transaction), conveyance, transfer or lease and (y) such supplemental indenture complies with this Article 6; and 
 (ii) all conditions precedent relating to such transaction provided herein have been complied with. 
 For purposes of this Section 6.01, any conveyance, transfer or lease of properties and assets of one or more Subsidiaries of the Company that would, if the Company had held such properties and assets
directly, have constituted the conveyance, transfer or lease of substantially all of the Company’s properties and assets shall be treated as such hereunder. 
 Section 6.02. Successor Corporation to be Substituted. Upon any such consolidation, merger (or similar transaction), conveyance or transfer (but not upon a lease) and the assumption by the
Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of, accrued and unpaid interest, if any, on all of the Notes, the due and
punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor
Company shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue in its own name, any or all of
the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in
this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the
Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of
the execution hereof. Upon any such consolidation, merger (or similar transaction), conveyance or transfer (but not upon a lease), the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall
thereafter have become such in the manner prescribed in this Article 6 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of
the Notes and from its obligations under this Indenture. 
 In case of any such consolidation, merger (or similar transaction),
conveyance, transfer or lease, changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

days after written notice of such default is delivered to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Notes then outstanding; 

(vii) a default by the Company or any of its Subsidiaries under any mortgage, indenture or instrument under which there
may be issued, or by which there may be secured or evidenced, any indebtedness of the Company and/or any of its Subsidiaries for money borrowed in excess of $25 million in the aggregate, whether such indebtedness exists as of the Original Issuance
Date or is thereafter created, which default (1) results in such indebtedness becoming or being declared due and payable or (2) constitutes a failure to pay the principal or interest of any such indebtedness when due and payable at its
stated maturity, upon required repurchase, upon declaration of acceleration or otherwise; 
 (viii) a final
judgment for the payment of $25 million or more (excluding any amounts covered by insurance) rendered against the Company or any Subsidiary of the Company, which judgment is not discharged or stayed within 60 days after (1) the date on which
the right to appeal thereof has expired if no such appeal has commenced, or (2) the date on which all rights to appeal have been extinguished; 

  
 35 









 (ix) the Company or any then-current Significant Subsidiary thereof shall
commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in
effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the
appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due;
or 
 (x) an involuntary case or other proceeding shall be commenced against the Company or any then-current
Significant Subsidiary thereof seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking
the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and
unstayed for a period of 30 consecutive days. 
 (b) Within the 30 days immediately following the occurrence of an Event of
Default or any Default, the Company shall deliver to the Trustee at its Corporate Trustee Office, in accordance with Section 14.01, written notice thereof in the form of an Officer’s Certificate describing each Event of Default or Default
that has occurred and is continuing and its status and explaining what action the Company is taking or proposes to take in respect thereof, which notice shall make explicit reference to this Indenture, the Notes and the Company. 

(c) Notwithstanding anything to the contrary in the Notes or elsewhere in this Indenture, except as provided in
Section 5.02(b) or (c), at the election of the Company, the sole remedy of Holders for an Event of Default relating to the failure by the Company to comply with its obligation to file reports, information or documents with the Trustee pursuant
to Section 5.02(a) (the “Company’s Filing Obligations”) shall, for the first 60 days after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest at a rate equal to
0.50% per annum on the principal amount of the Notes then outstanding. Such Additional Interest shall be in addition to, and not in lieu of, any Additional Interest that the Company is required to pay under Section 5.02(b) or (c).
If the Company makes such election to pay Additional Interest, such Additional Interest shall be payable in arrears on each Interest Payment Date following the date on which such Event of Default first occurred in the same manner as stated interest
payable on the Notes. On the 61st day following the date
on which such Event of Default first occurred (if the failure to comply with the Company’s Filing Obligations is not cured or waived prior to such 61st day), the Notes shall be subject to acceleration as provided in Section 7.02. The provisions contained in this
Section 7.01(c) shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. If the Company does not elect to pay Additional Interest upon an Event of Default in accordance with this Section 7.01(c),
the Notes shall be subject to acceleration as provided in Section 7.02. In order to elect to pay Additional Interest as the sole remedy for the first 60 days after the occurrence of an Event of Default relating to the failure by the Company to
comply with the Company’s Filing Obligations, 

  
 36 









 
the Company must notify, in the manner provided for in Section 14.01, all Holders of the Notes, the Paying Agent and the Trustee of such election at any time on or before the date on which
such Event of Default first occurs (which notice shall include a statement as to the date from which Additional Interest is payable and, in the case of the Trustee, shall be delivered to its Corporate Trust Office and shall make explicit reference
to this Indenture, the Notes and the Company). Unless and until a Trust Officer receives at the Corporate Trust Office such notice, the Trustee may assume without inquiry that no Additional Interest is payable. Upon failure by the Company to timely
give such notice to pay such Additional Interest, or if the Company has provided such notice but has failed to pay such Additional Interest, the Notes shall be immediately subject to acceleration as provided in Section 7.02. If Additional
Interest has been paid by the Company directly to the Persons entitled to it, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. 

Section 7.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 7.01(a)(ix) or
7.01(a)(x) with respect to the Company) occurs and is continuing, and in each and every such case, except for any Notes the principal of which shall have already become due and payable, either the Trustee, by notice to the Company, or the Holders of
at least 25% in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare 100% of the principal amount of, and accrued and unpaid interest
on, all of the Notes then outstanding, to be due and payable immediately, and upon such a declaration, the same shall be immediately due and payable. If an Event of Default specified in Section 7.01(a)(ix) or 7.01(a)(x) occurs with respect to
the Company, 100% of the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding shall, automatically and without any notice or other action by the Trustee or any Holder, be and become immediately due and
payable, to the fullest extent permitted by applicable law. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by written notice to the Trustee and the Company, and without notice to any other Holder, may
rescind any acceleration of the Notes if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than the nonpayment of the principal of and
interest on the Notes that has become due solely by such acceleration, have been cured or waived. Any such rescission shall not affect any subsequent Default or impair any right consequent thereon. 

Section 7.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of the Notes in the
proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative. 
 Section 7.04. Waiver of Past Defaults. The
Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by written notice to the Trustee and the Company and without notice to any other Holder, may waive any Default, except with respect to (a) any


  
 37 









 
failure by the Company to pay the principal of or accrued interest on the Notes (including the Fundamental Change Purchase Price or Redemption Price, if applicable), (b) any failure by the
Company to comply with its obligations to purchase Notes when required to do so under Article 3 or (c) any failure by the Company to comply with any covenant or provision of this Indenture or the Notes that under Section 10.02 cannot be
modified or amended without the consent of each Holder. Any such waiver shall not affect any subsequent or other Default or impair any right consequent thereon. 
 Section 7.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee; provided that (i) the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the
Trustee determines is unduly prejudicial to the rights of any other Holder or would involve the Trustee in personal liability and (ii) for the avoidance of doubt, the Trustee may take any other action deemed proper by the Trustee that is not
inconsistent with such direction. Subject to Article 8, if an Event of Default has occurred and is continuing, the Trustee shall be under no obligation to exercise any of its rights or powers hereunder at the request or direction of any of the
Holders unless such Holders have offered to the Trustee indemnity or security reasonably satisfactory to the Trustee against any loss, liability or expense caused by taking such action. 

Section 7.06. Limitation on Suits. Except to enforce its rights as provided in Section 7.07, no Holder may institute any
proceeding, judicial or otherwise, with respect to this Indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (a) such Holder shall have previously given to the Trustee written notice that an Event of Default has occurred and is continuing; 
 (b) the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding shall have made a written request to the Trustee to take such action; 

(c) such Holder or Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the
costs and other liabilities of compliance with such written request; 
 (d) the Trustee shall not have complied with such
written request during the first 60 days after receiving such notice, request and offer of security or indemnity; and 
 (e)
during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes shall not have given the Trustee a direction inconsistent with such written request. 

A Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other
Holder. 
 Section 7.07. Rights of Holders to Receive Payment; Suit Therefor. Notwithstanding any other provision of
this Indenture, each Holder shall have the right to receive payment or delivery, 

  
 38 









 
as the case may be, of (i) the principal (including the Fundamental Change Purchase Price or Redemption Price, if applicable) of, (ii) accrued and unpaid interest on and (iii) the
consideration due upon conversion of, its Notes, on or after the respective due dates expressed or provided for in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, and such right to
receive such payment or delivery, as the case may be, on or after such respective dates shall not be impaired or affected without the consent of such Holder and shall not be subject to the requirements of Section 7.06. Payments of the
Redemption Price, the Fundamental Change Purchase Price, cash due upon conversion (if any), and principal and interest that are not made when due shall accrue interest per annum at the then-applicable interest rate plus one percent from the
applicable due date expressed in this Indenture. 
 Section 7.08. Collection Suit by Trustee. If an Event of Default
specified in Section 7.01(a)(i) or 7.01(a)(ii) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on
any unpaid interest, if any, to the extent lawful) and the amounts provided for in Section 8.06. 
 Section 7.09.
Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to
the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any
such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, if the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 8.06. 
 Section 7.10. Priorities. Any monies collected by the Trustee pursuant to this Article 7 with respect to the Notes and any other monies or property distributable in respect of the
Company’s obligations under this Indenture following an Event of Default specified in Section 7.01(a)(ix) or Section 7.01(a)(x) with respect to the Company shall be applied in the following order: 

FIRST: to the Trustee (including any predecessor trustee) for amounts due under Section 8.06; 

SECOND: to Holders for amounts due and unpaid on the Notes for principal, accrued and unpaid interest, if any, payment of the Fundamental
Change Purchase Price and the cash deliverable upon conversion of Notes then submitted for conversion, as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Notes; and 

THIRD: the balance, if any, to the Company. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 7.10. 

  
 39 









 Section 7.11. Undertaking for Costs. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the
suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the
party litigant. This Section 7.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 7.07 or a suit by Holders of more than 10% in aggregate principal amount of the Notes at the time outstanding. 

Section 7.12. Waiver of Stay or Extension Laws. The Company (to the extent it may lawfully do so) shall not at any time
insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and
the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted. 
 ARTICLE 8 

TRUSTEE 
 Section 8.01. Duties of Trustee.  
 (a) If an Event of Default has
occurred and is continuing, 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 in the conduct of such
person’s own affairs. 
 (b) Except during the continuance of an Event of Default: 

(i) the Trustee 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; and 
 (ii) in the
absence of bad faith or negligence on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the
requirements of this Indenture; provided, however, that the Trustee will examine the certificates and opinions to determine whether they conform to the requirements set forth in this Indenture (but need not confirm or investigate the
accuracy of any mathematical calculations or other facts, statements, opinions or conclusions stated therein). 
 (c) The
Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 

  
 40 









 (i) this sub-section (c) does not limit the effect of the remainder of
this Section 8.01; 
 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a
Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 

(iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance
with a direction received by it pursuant to Section 7.05 hereof, or exercising any trust or power conferred upon the Trustee under this Indenture absent negligence or willful misconduct. 

(d) All monies received by the Trustee shall, until delivered to the applicable Holders as herein provided, be held in trust in a
non-interest bearing account for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. 

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in
the performance of any of its duties hereunder or in the exercise of any of its rights or powers. The Trustee shall not be required to give any bond or surety in respect of the performance of its powers or duties hereunder. 

(f) Whether herein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Article 8, and the provisions of this Article 8 shall apply to the Trustee, Registrar, Paying Agent, Bid Solicitation Agent and Conversion Agent. 

(g) The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default, other than a failure
by the Company to make any payment hereunder when due, unless (i) written notice of such default or Event of Default from the Company or any Holder is received by a Trust Officer of the Trustee at the Corporate Trust Office of the Trustee, and
such notice references the Notes and this Indenture or (ii) a Trust Officer shall have actual knowledge thereof. 

Section 8.02. Rights of Trustee.  
 (a) The Trustee may conclusively rely upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of
indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in any such resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document. The Trustee may, however, in its discretion make such further inquiry or investigation into such facts or
matters as it may see fit and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole expense of
the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

  
 41 









 (b) Before the Trustee acts or refrains from acting (except in connection with an
application for authorization of Notes pursuant to Section 2.03) at the direction of the Company, it may require an Officer’s Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in
good faith in reliance on the Officer’s Certificate or Opinion of Counsel and may conclusively rely upon such Officer’s Certificate or Opinion of Counsel. 
 (c) The Trustee may act through agents, attorneys or custodians and shall not be responsible for the misconduct or negligence of any agent, attorney or custodian appointed with due care hereunder.

 (d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized
or within the rights or powers conferred upon it by this Indenture; provided, however, that the Trustee’s conduct does not constitute willful misconduct or negligence. 

(e) The Trustee may consult with counsel of its own selection, and the written advice or opinion of counsel with respect to legal matters
relating to this Indenture and the Notes shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such
counsel. 
 (f) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty
unless so specified herein. 
 (g) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it
by this Indenture at the request or direction of any of the Holders, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee in accordance with such Section. 

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder, including, without limitation, the Registrar, Paying Agents, Bid
Solicitation Agent and Conversion Agent. 
 (i) The Trustee may request that the Company deliver a certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which certificate may be signed by any person authorized to sign an Officer’s Certificate, including any person
specified as so authorized in any such certificate previously delivered and not superseded. 
 (j) Anything in this Indenture
notwithstanding, in no event shall the Trustee be liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit), even if the Trustee has been advised as to the likelihood
of such loss or damage and regardless of the form of action. 

  
 42 









 (k) Any request or direction of the Company mentioned herein shall be sufficiently evidenced
by a Company Order or any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution. 

Section 8.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Bid Solicitation Agent (if other than the Company), Conversion Agent or co-registrar
may do the same with like rights. However, the Trustee must comply with Section 8.10. 
 Section 8.04.
Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity, sufficiency, priority or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the
proceeds from the Notes, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of
authentication. The Trustee shall have no duty to monitor or investigate the Company’s compliance with or the breach of, or cause to be performed or observed, any representation, warranty, or covenant, or agreement of any Person, other than the
Trustee, made in this Indenture. 
 Section 8.05. Notice of Defaults. If a Default or Event of Default occurs and is
continuing and is known to the Trustee, the Trustee shall mail to each Holder notice of such Default or Event of Default within 90 days after it occurs; provided that except in the case of a Default described in Section 7.01(a)(i),
7.01(a)(ii) or 7.01(a)(iii), the Trustee may withhold the notice if and so long as a committee of Trust Officers of the Trustee in good faith determines that withholding the notice is in the interests of the Holders. 

Section 8.06. Compensation and Indemnity.  
 (a) The Company shall pay to the Trustee from time to time such compensation as shall be agreed upon from time to time in writing for all services rendered by it hereunder in any capacity. The
Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket fees and expenses incurred or made by it, including
costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation, fees and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts and of all
Persons not regularly in its employ. The Company shall fully indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith against any and all loss, liability, claim, damage or
expense (including reasonable attorneys’ fees and expenses) incurred by it in connection with the acceptance and administration of this trust and the performance of its duties hereunder in any capacity, including the costs and expenses of
defending itself against any claim (whether asserted by the Company, any Holder or any other Person). The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s
own willful misconduct or negligence. All indemnifications and releases from liability granted hereunder to the Trustee shall extend to its officers, directors, employees, agents, attorneys, custodians, successors and assigns. 

  
 43 









 (b) To secure the Company’s payment obligations under this Section 8.06, the
Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay the principal, accrued and unpaid interest, if any, or payment of the Fundamental Change
Purchase Price or Redemption Price on particular Notes. 
 (c) The Company’s payment obligations pursuant to this
Section 8.06 shall survive the resignation or removal of the Trustee and the discharge of this Indenture. If the Trustee incurs expenses (including the reasonable charges and expenses of its counsel) after the occurrence of a Default specified
in Section 7.01(a)(ix) or Section 7.01(a)(x) with respect to the Company, the expenses are intended to constitute expenses of administration under applicable bankruptcy laws. 

(d) “Trustee” for purposes of this Section shall include any predecessor Trustee; provided, however, that the negligence,
willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 
 (e) The
provisions of this Section shall survive the satisfaction and discharge of the Indenture, the termination for any reason of this Indenture, and the resignation or removal of the Trustee. 

Section 8.07. Replacement of Trustee.  
 (a) The Trustee may resign at any time by notifying the Company in writing and by mailing notice thereof to the Holders at their addresses as they shall appear on the Register. Upon receiving such notice
of resignation, the Company shall promptly appoint a successor Trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the
successor Trustee. If no successor Trustee shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to
the Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor Trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may on behalf of himself or herself and
all others similarly situated, petition any such court for the appointment of a successor Trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor Trustee. 

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

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 8.10 and shall fail to resign
after written request therefor by the Company or by any such Holder, or 
 (ii) the Trustee shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, 

  
 44 









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

(c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and
nominate a successor Trustee that shall be deemed appointed as successor Trustee, unless within ten days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Holder, upon the terms
and conditions and otherwise as specified in clause (a) above, may petition any court of competent jurisdiction for an appointment of a successor Trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor Trustee pursuant to any of the provisions of this Section 8.07 shall become effective upon acceptance of appointment by
the successor Trustee as provided in Section 8.08. 
 Section 8.08. Acceptance by Successor Trustee. Any
successor Trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if
originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor Trustee, the Trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.06,
execute and deliver an instrument transferring to such successor Trustee all the rights and powers of the Trustee so ceasing to act. Upon request of any such successor Trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor Trustee all such rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a lien prior to the Notes on all money or property held or collected by the Trustee, other
than money or property held in trust to pay the principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price or Redemption Price on particular Notes, to secure any amounts then due it pursuant to the provisions
of Section 8.06. 
 No successor Trustee shall accept appointment as provided in this Section 8.08 unless at the time
of such acceptance such successor Trustee shall be eligible under the provisions of Section 8.10. 
 Upon acceptance of
appointment by a successor Trustee as provided in this Section 8.08, each of the Company and the successor Trustee, at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such
Trustee hereunder to the Holders at their addresses as they shall appear on the Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor Trustee, the successor Trustee shall cause such
notice to be mailed at the expense of the Company. 

  
 45 









 Section 8.09. Successor Trustee by Merger.  

(a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or
assets (including administration of this Indenture) to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee; provided
that if such successor Trustee is not eligible to act as Trustee pursuant to Section 8.10, such successor Trustee shall promptly resign pursuant to Section 8.07. 
 (b) In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been
authenticated, any such successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee. 
 Section 8.10. Eligibility; Disqualification. The Trustee must be a Person who is eligible to act as an indenture trustee under the TIA and must have a combined capital and surplus of at least
$50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect specified in this Article. 
 ARTICLE 9 

DISCHARGE OF INDENTURE 

Section 9.01. Discharge of Liability on Notes. When (a) the Company delivers to the Registrar all outstanding Notes
(other than Notes replaced pursuant to Section 2.07) for cancellation or (b) all outstanding Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Purchase Date, upon conversion, upon redemption or
otherwise, and the Company irrevocably deposits with the Trustee or delivers to the Holders, as applicable, cash (and/or, if applicable, shares of Common Stock solely to satisfy outstanding conversions) sufficient to pay, or, if applicable, satisfy
the Company’s Conversion Obligation with respect to, all amounts due and owing on all outstanding Notes (other than Notes replaced pursuant to Section 2.07), and, in either case, the Company pays all other sums payable hereunder by the
Company with respect to the outstanding Notes, then this Indenture shall, subject to Section 8.06, cease to be of further effect with respect to the Notes or any Holders. At the cost and expense of the Company, the Trustee shall acknowledge
satisfaction and discharge of this Indenture with respect to the Notes on demand of the Company accompanied by an Officer’s Certificate and an Opinion of Counsel.

Section 10.03. Execution of Supplemental Indentures. Upon the request of the Company, the Trustee shall sign any supplemental

 ARTICLE 11 
 CONVERSIONS 
 Section 11.01. Conversion Privilege and
Consideration.  
 (a) On or before June 30, 2013, the Notes will not be convertible under any circumstances. Subject
to and upon compliance with the provisions of this Indenture, a Holder shall have the right, at such Holder’s option, to convert the principal amount of its Notes, or any portion of such principal amount that is equal to $1,000 or an integral
multiple thereof, (i) subject to satisfaction of one or more of the conditions described in Section 11.01(b), at any time following June 30, 2013 and prior to the Close of Business on the Business Day immediately preceding
October 1, 2018 during the periods set forth in Section 11.01(b), and (ii) irrespective of the conditions described in Section 11.01(b), on or after October 1, 2018 and prior to the Close of Business on the Business Day
immediately preceding the Maturity Date, in each case, at an initial conversion rate of 46.1723 shares of Common Stock (subject to adjustment as provided in this Article 11, the “Conversion Rate”) per $1,000 principal amount of
Notes (subject to the settlement provisions of Section 11.03, the “Conversion Obligation”). 
 (b)

 (i) Prior to the Close of Business on the Business Day immediately preceding October 1, 2018, the Notes
may be surrendered for conversion during any fiscal quarter (and only during such fiscal quarter) commencing after June 30, 2013, if, for at least 20 Trading Days (whether or not consecutive) during the 30 consecutive Trading Day period ending
on the last Trading Day of the immediately preceding fiscal quarter, the Last Reported Sale Price of the Common Stock on such Trading Day is greater than or equal to 130% of the applicable Conversion Price on such Trading Day (such condition, the
“Sale Price Condition”). If the Sale Price Condition has been met, the Company shall notify Holders of its satisfaction and of the resulting right of Holders to convert their Notes within one Business Day of the Sale Price Condition
being met. 
 (ii) Following June 30, 2013 and prior to the Close of Business on the Business Day
immediately preceding October 1, 2018, the Notes may be surrendered for conversion during the five consecutive Business Day period immediately following any five consecutive Trading Day period (the “Measurement Period”) in
which, for each Trading Day of such Measurement Period, the Trading Price per $1,000 principal amount of Notes (as determined following a request by a Holder in accordance with the procedures set forth in this Section 11.01(b)(ii) and the
definition of “Trading Price” in Section 1.01), was less than 98% of the product of (x) the Last Reported Sale Price of the Common Stock on such Trading Day and (y) the Conversion Rate on such Trading Day (such product, the
“Intrinsic Value,” and such condition, the “Trading Price Condition”). The Trading Prices shall be determined by the Bid Solicitation Agent 

  
 49 









 
pursuant to this Section 11.01(b)(ii) and the definition of Trading Price in Section 1.01. The Company shall provide written notice to the Bid Solicitation Agent (if other than the
Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of “Trading Price” in Section 1.01, along with appropriate contact information for each. 

(A) The Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Notes unless the Company has
requested that the Bid Solicitation Agent determine the Trading Price of the Notes. The Company shall have no obligation to make such a request unless a Holder of Notes (x) provides the Company with reasonable evidence that the Trading Price
per $1,000 principal amount of Notes for the immediately following Trading Day would be less than 98% of the Intrinsic Value of the Notes for such Trading Day and (y) requests that the Company request the Bid Solicitation Agent to determine the
Trading Price of the Notes. 
 (B) Upon receipt from a Holder of such evidence and such a request, the Company
shall instruct the Bid Solicitation Agent to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until a Trading Day occurs in which the Trading Price per $1,000 principal amount of Notes for
such Trading Day is greater than or equal to 98% of the Intrinsic Value of the Notes for such Trading Day. 
 (C)
If the Trading Price Condition has been met on any Trading Day, the Company shall notify Holders of its satisfaction and of the resulting right of Holders to convert their Notes on such Trading Day. If, on any Trading Day after the Trading Price
Condition has been met, the Bid Solicitation Agent determines that the Trading Price per $1,000 principal amount of Notes for such Trading Day is greater than or equal to 98% of the Intrinsic Value of the Notes for such Trading Day, the Company
shall promptly so notify the Holders that the Trading Price Condition is no longer met. 
 (iii) If, following
June 30, 2013 and prior to the Close of Business on October 1, 2018, the Company elects to: 
 (A)
issue to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the
Common Stock at a price per share of Common Stock less than the average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of
announcement of such issuance; or 
 (B) distribute to all or substantially all holders of the Common Stock the
Company’s assets, 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 immediately preceding the date of announcement for such distribution, 

  
 50 









 
then, in each case, at least 35 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution, the Company shall mail notice to the Holders describing such issuance or
distribution, the Holders’ rights to convert their Notes in accordance with this Section 11.01(b)(iii), the Conversion Rate in effect on the date the Company mails such notice, any adjustments to the Conversion Rate that must be made as a
result of such issuance or distribution, and the effective date for any such adjustments. Once the Company has given such notice, a Holder may surrender its Notes for conversion at any time until the earlier of (x) the Close of Business on the
Business Day immediately preceding such Ex-Dividend Date and (y) the Company’s announcement that such issuance or distribution will not take place. 
 (iv) If, prior to the Close of Business on October 1, 2018, the Company or any third party publicly announces a transaction or event that would, if consummated, constitute a Fundamental Change, a
Make-Whole Fundamental Change or Share Exchange Event (regardless of whether the Holders would have the right to require the Company to purchase their Notes pursuant to Article 3), or any such transaction or event occurs without any public
announcement, the Company shall mail notice (a “Specified Corporate Transaction Notice”) of such Specified Corporate Transaction to the Holders within one Business Day of the first public announcement of such transaction or event
or, in the case that no public announcement is made, the occurrence of such transaction or event. Upon receiving notice or otherwise becoming aware of a potential Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event, the Company
shall use commercially reasonable efforts to announce or cause the announcement of such potential transaction or event in time to deliver the related Specified Corporate Transaction Notice at least 35 Scheduled Trading Days prior to the anticipated
effective date for such potential Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event. For any such potential Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event, the Specified Corporate Transaction Notice
shall describe: 
 (A) the potential transaction or event; 

(B) the anticipated effective date of such transaction or event; 

(C) the Holders’ right to convert their Notes in accordance with this Section 11.01(b)(iv); 

(D) the Conversion Rate in effect on the date the Company mails such notice; 

(E) that an adjustment to the Conversion Rate is expected to be made pursuant to Section 11.05 as a result of such
transaction or event and the formula for determining such adjustment; 

  
 51 









 (F) whether the relevant transaction or event is expected to constitute a
Share Exchange Event, and, if so, that the Notes will become convertible into Reference Property, subject to the settlement provisions of the Indenture; 
 (G) whether the relevant transaction or event is expected to constitute a Fundamental Change, and, if so, that Holders will have the right to require the Company to purchase their Notes pursuant to
Article 3; and 
 (H) whether the relevant transaction or event is expected to constitute a Make-Whole
Fundamental Change, and, if so, that the Conversion Rate will be increased under Section 11.07 for Notes converted in connection with such Make-Whole Fundamental Change. 
 Upon the later of (x) the Company’s delivery of a Specified Corporate Transaction Notice with respect to any potential Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event
and (y) the first Business Day following June 30, 2013, a Holder may surrender its Notes for conversion at any time until the 35th Trading Day immediately following the later of (x) the effective date of such transaction or event and
(y) June 30, 2013, or, if such transaction or event constitutes a Fundamental Change with an effective date following June 30, 2013, the Business Day immediately preceding the related Fundamental Change Purchase Date. 

(v) If the Company calls any or all of the Notes for redemption pursuant to Article 4, Holders may convert their Notes at
any time on or after the date the Company delivers the relevant Redemption Notice to Holders and prior to the Close of Business on the Business Day prior to the relevant Redemption Date, even if the Notes are not otherwise convertible at such time.
After that time, the right of Holders to convert their Notes on account of the Company’s delivery of such Redemption Notice shall expire, unless the Company defaults in the payment of the Redemption Price, in which case the Notes will be
convertible under this Section 11.01(b)(v) until the Redemption Price has been paid or duly provided for. 

(vi) Following June 30, 2013, holders may convert all or a portion of their Notes on any date prior to the
Company’s receipt of Stockholder Approval. 
 Section 11.02. Conversion Procedure.  

(a) To convert a Note or portion thereof, a Holder or beneficial owner, as the case may be, must (i) in the case of a Global Note,
(a) comply with the procedures of the Depositary then in effect for converting a beneficial interest in a global note and (b) if applicable, pay all funds required under Sections 11.02(g) and 11.02(h) below, and (ii) in the case of a
Certificated Note, (a) complete and manually sign the conversion notice in the form attached to such Certificated Note (a “Notice of Conversion”) or a facsimile of the Notice of Conversion, (b) deliver the Notice of
Conversion, which is irrevocable, and the Certificated Note to the Conversion Agent, (c) if required, furnish appropriate endorsements and transfer documents, (d) if applicable, pay all funds required under Section 11.02(h) below, and
(e) if applicable, pay all funds required under Section 11.02(g) below. 

  
 52 









 (b) A Note shall be deemed to have been converted at the Close of Business on the first
Business Day (the “Conversion Date”) on which (i) the Holder thereof satisfies all of the requirements set forth in Section 11.02(a) with respect to such Note and (ii) the conversion of such Note is not otherwise
prohibited by Section 3.04(a) hereof. 
 (c) If the last day during any period on which a Note may be converted is not a
Business Day, the Note may be surrendered on the immediately following day that is a Business Day. Upon the conversion of a Note, the Conversion Agent, as promptly as possible, and in no event later than one Business Day immediately following the
Conversion Date for the Note, will provide the Company with notice of the conversion of the Note, and the Company, as promptly as possible, and in no event later than two Business Days after such Conversion Date, will notify the Trustee, if other
than the Conversion Agent, of the conversion of the Note. 
 (d) If a Holder converts the entire principal amount of a Note,
such Person will no longer be a Holder of such Note, except that (i) such Holder shall have the right hereunder to receive the consideration due upon conversion and (ii) if the relevant Conversion Date occurred between a Record Date and on
or prior to the corresponding Interest Payment Date, the Holder of record of such Note shall have the right to receive the related interest payment on such Interest Payment Date. 

(e) If a Holder surrenders only a portion of a Certificated Note for conversion, promptly after the Conversion Date for such portion, the
Company shall execute and the Trustee shall authenticate and deliver to such Holder, a new Certificated Note in an authorized denomination equal to the aggregate principal amount of the unconverted portion of the surrendered Note. Upon the
conversion of an interest in a Global Note, the Trustee shall promptly make a notation on the “Schedule of Exchanges of Notes” of such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify
the Trustee in writing upon any conversion of a Note effected through any Conversion Agent other than the Trustee. 
 (f) Prior
to obtaining Stockholder Approval, the converting Holder (or its designee) shall be treated as the holder of record of the shares of Common Stock to be delivered upon conversion as of the relevant Conversion Date. After obtaining Stockholder
Approval, if any shares of Common Stock are issuable upon the conversion of a Note, the converting Holder (or its designee) shall be treated as the holder of record of such shares as of the relevant Conversion Date (in the case of Physical
Settlement) or the last VWAP Trading Day of the relevant Observation Period for such Note (in the case of Combination Settlement). 
 (g) Notwithstanding Section 11.03(d), if a Holder converts its Note after the Close of Business on a Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such
Record Date, the Holder of such Note at the Close of Business on such Record Date shall receive the interest payment payable on such Note on such corresponding Interest Payment Date, notwithstanding the conversion. Any Note converted during the
period beginning at the Close of Business on any Record Date and ending at the Open of Business on the Interest Payment Date corresponding to such Record Date must be accompanied by funds equal to the amount of interest payable on such Note on such
corresponding Interest Payment Date; provided, however, that no such payment need be made: (i) for a Note surrendered for 

  
 53 









 
conversion after the Close of Business on the Record Date immediately preceding the Maturity Date, (ii) if the Company has specified a Redemption Date or Fundamental Change Purchase Date
that is after such Record Date and on or prior to such corresponding Interest Payment Date, or (iii) to the extent of any Defaulted Interest, if any Defaulted Interest exists at the time of conversion with respect to such Note. For the
avoidance of doubt, the Company shall pay interest on the Maturity Date on all Notes converted after the Record Date immediately preceding the Maturity Date, and converting Holders shall not be required to pay to the Company equivalent interest
amounts. 
 (h) If a Holder converts a Note, the Company shall pay any documentary, stamp or similar issue or transfer tax due
on the issue of any shares of Common Stock upon such conversion; provided that if such tax is due because such converting Holder requested that such shares of Common Stock be issued in a name other than such Holder’s name, such Holder
shall pay such tax. 
 Section 11.03. Settlement Upon Conversion.  

(a) Except as provided in Section 11.07(e), upon conversion of any Note, if the Company has not received the requisite approval from
its stockholders in accordance with NASDAQ Stock Market Rule 5635 (the “Stockholder Approval”) to issue 20% or more of its Common Stock upon conversion of the Notes prior to the relevant Conversion Date, the Company shall deliver to
the converting Holder, in respect of each $1,000 principal amount of Notes being converted, a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date, together with a cash payment, if applicable, in lieu of any
fractional share of Common Stock equal to the product of (i) such fraction of a share and (ii) the Daily VWAP on the relevant Conversion Date. The Company shall deliver the consideration due in respect of the Conversion Obligation on the
third Business Day immediately following the relevant Conversion Date. 
 (b) The provisions of this Section 11.03(b),
whether or not expressly stated therein, shall only apply to Conversion Dates following the Company’s receipt of Stockholder Approval. 
 (i) Except as provided in Section 11.07(e), upon conversion of any Note, if the Company has received Stockholder Approval prior to the relevant Conversion Date, the Company shall pay or deliver, as
the case may be, to the converting Holder cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 11.03(b)(vii)
(“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 11.03(b)(vii) (“Combination
Settlement”), at the Company’s election (each of these settlement methods a “Settlement Method”). 
 (ii) All conversions occurring on or after the 30th Scheduled Trading Day immediately preceding the Maturity Date and all conversions occurring during a Redemption Period, shall be settled using the same
Settlement Method. Subject to the foregoing, if the Company has received Stockholder Approval, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but


  
 54 









 
the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates, and the Company may elect a Settlement Method
with respect to certain Conversion Dates and not with respect to other Conversion Dates. 
 (iii) The Company
shall deliver a notice (the “Settlement Method Notice”) of the Settlement Method elected by the Company in respect of any Conversion Date or any of the periods described below, as the case may be: 

(A) in the applicable Redemption Notice, with respect to any conversion following delivery of a Redemption Notice by the
Company and prior to the Close of Business on the Business Day immediately preceding the related Redemption Date (such period, a “Redemption Period”); 

(B) by written notice to all Holders of Notes, the Trustee and the Conversion Agent on or prior to the 30th Scheduled
Trading Day immediately preceding the Maturity Date, in the case of any conversion occurring on or after such date, other than during a Redemption Period; or 
 (C) by written notice to the converting Holder, the Trustee and the Conversion Agent, prior to the Close of Business on the first Scheduled Trading Day following the relevant Conversion Date, in the case
of any other conversion. 
 (iv) Any Settlement Method Notice shall specify the relevant
Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Method Notice shall indicate the Specified Dollar Amount. If the Company has received Stockholder Approval and does not timely deliver a Settlement
Method prior to the deadline set forth in this Section 11.03(b)(iii), the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect
of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. If the Company elects Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified
Dollar Amount in the relevant Settlement Method Notice, the Specified Dollar Amount shall be deemed to be $1,000. The Company agrees that it will not seek Stockholder Approval during a Redemption Period or during the period following the 30th Scheduled Trading Day immediately preceding the Maturity Date
through the Maturity Date. 
 (v) The cash, shares of Common Stock or combination of cash and shares of Common
Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 
 (A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal
amount of Notes being converted a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date, together with cash in lieu of fractional shares pursuant to Section 11.03(b)(vii); 

  
 55 









 (B) if the Company elects to satisfy its Conversion Obligation in respect of
such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 25 consecutive
VWAP Trading Days during the related Observation Period; and 
 (C) if the Company elects (or is deemed to have
elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount
equal to the sum of the Daily Settlement Amounts for each of the 25 consecutive VWAP Trading Days during the related Observation Period. 
 (vi) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly
after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of any fractional share, the Company shall notify the Trustee and the Conversion Agent (if other than
the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have
no responsibility for any such determination. 
 (vii) The Company shall not issue any fractional share of Common
Stock upon conversion of the Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily
VWAP on the last VWAP Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares that shall be issued
upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Observation Period and any fractional shares remaining after such computation shall be paid in cash. 

(viii) The Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation
on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following the last VWAP Trading Day of the Observation Period, in the case of any other
Settlement Method. 
 (c) If a Holder surrenders more than one Note for conversion on a single Conversion Date, the number of
shares of Common Stock, if any, that the Company will deliver, and the amount of cash that the Company will pay pursuant to Section 11.03(a) or Section 11.03(b)(vii) in lieu of fractional shares of Common Stock, if any, shall be determined
based on the total principal amount of Notes so surrendered by such Holder. 

  
 56 









 (d) If a Holder converts a Note, except as set forth in Section 11.02(g), (i) such
Holder shall not receive any separate cash payment (in addition to the Conversion Obligation) for accrued and unpaid interest on such Note and (ii) the Company’s delivery to such converting Holder of the Conversion Obligation shall be
deemed to satisfy in full the Company’s obligation to pay to such Holder (A) the principal amount of such converted Note and (B) accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date. As a result,
subject to Section 11.02(g), accrued and unpaid interest, if any, on a converted Note to but, excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of
Notes, subject to Section 11.02(g), accrued and unpaid interest, if any, shall be deemed to be paid first out of the cash paid upon such conversion, if any. 
 (e) Notices. 
 (i) On the second Business Day immediately
following the Conversion Date for any Notes, the Company shall deliver written notice to the Trustee stating (2) the aggregate principal amount of Notes converted on such Conversion Date, (3) whether the Company has made a Settlement
Method election with respect to such Conversion Date, and (4) if the Company has made a Settlement Method election for such Conversion Date, the Specified Dollar Amount for such Conversion Date (if applicable). 

(ii) On the first Business Day immediately following the last VWAP Trading Day of the Observation Period for each
Conversion Date to which Cash Settlement or Combination Settlement applies, the Company shall deliver written notice to the Trustee stating (1) the aggregate principal amount of Notes that were converted on such Conversion Date, (2) the
aggregate amount of cash and the aggregate number of Shares that the Company is obligated to deliver to settle all of the Notes converted on such Conversion Date, and (3) the Daily Conversion Values or Daily Settlement Amounts, as the case may
be, for each VWAP Trading Day of the Observation Period for such Conversion Date. 
 (iii) If the Company
receives Stockholder Approval on any day, the Company shall so notify Holders, the Trustee and the Conversion Agent prior to the Close of Business on the Business Day immediately following such day that the Stockholder Approval is received.

 Section 11.04. Covenants Relating to Underlying Shares.  

(a) The Company shall, until all Notes cease to be outstanding and any consideration due upon conversion has been paid or delivered, as
the case may be, reserve out of its authorized but unissued shares of Common Stock that have not been reserved for other purposes a number of shares of Common Stock, in the aggregate, equal to the product of the Maximum Conversion Rate and the
aggregate principal amount of Notes then outstanding (expressed in thousands of dollars), to permit the conversion of the Notes. 

  
 57 









 (b) The Company covenants that any shares of Common Stock delivered upon conversion of the
Notes shall be duly and validly issued and fully paid and nonassessable, and shall be free from preemptive rights and shall be free of any lien or adverse claim or from any taxes or charges with respect to the issue thereof. 

(c) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require
registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission,
secure such registration or approval, as the case may be. 
 (d) In addition, the Company will cause any such shares of Common
Stock to be listed on any stock exchange on which the Common Stock is then listed and will comply with any stock exchange rules applicable to the Notes and/or the Common Stock issuable upon conversion of the Notes. 

Section 11.05. Adjustments to the Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as
described in this Section 11.05, except that the Company shall not make any adjustments to the Conversion Rate for any Holder that participates (as a result of holding the Notes, and at the same time as the holders of the Common Stock
participate) in any of the transactions described below as if such Holder held, for each $1,000 principal amount of Notes held, a number of shares of the Common Stock equal to the applicable Conversion Rate, without having to convert its Notes.

 (a) Dividends, Distributions, Splits and Combinations. If the Ex-Dividend Date occurs for any issuance by the Company
of solely shares of the Common Stock as a dividend or distribution on all or substantially all of the shares of the Common Stock, or if the Company effects a share split or a share combination of the Common Stock, the Conversion Rate shall be
adjusted based on the following formula: 
  
 



 
 where: 
  

			
		
	CR0 =	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the
effective date of such share split or combination, as the case may be;
		
	CR1 =	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such effective date, as the case may be;
		
	OS0 =	  	the number of shares of the Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or effective date, as the case may be;
and


  
 58 










			
		
	OS1 =	  	the number of shares of the Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as the case may
be.

 Any adjustment made under this Section 11.05(a) 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 combination, as the case may be. If any dividend or distribution of the type described in this Section 11.05(a) is declared but not
so paid or made, then the Conversion Rate shall immediately be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution to the Conversion Rate that would then be in effect had such dividend or
distribution not been declared or announced. The “effective date,” with respect to a share split or combination, means the first date on which the shares of the Common Stock trade in the applicable exchange or in the applicable market,
regular way, reflecting the relevant share split or share combination, as applicable. 
 (b) Adjustment for Rights Issue.
If the Ex-Dividend Date occurs for any issuance by the Company to all or substantially all holders of the Common Stock of any rights, options or warrants entitling the holders of such rights, options or warrants for a period of not more than 60
calendar days after the announcement 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 ten consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be adjusted based on the following formula: 

 
 



 
 where: 
  

			
		
	CR0 =	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;
		
	CR1 =	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such issuance;
		
	OS0 =	  	the number of shares of the Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;
		
	X =	  	the total number of shares of the Common Stock issuable pursuant to such rights, options or warrants;
		
	Y =	  	the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of
the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any adjustment made under this Section 11.05(b) shall be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after the 

  
 59 









 
Open of Business on the Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion
Rate shall be readjusted, as of the date of such expiration, to the Conversion Rate that would then be in effect had the adjustment made upon the issuance of such rights, options or warrants been made on the basis of delivery of only the number of
shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall immediately be readjusted, as of the scheduled issuance date, to equal the Conversion Rate that would then be in effect had
the relevant adjustment pursuant to this Section 11.05(b) not occurred. 
 For purposes of this Section 11.05(b) and
Section 11.01(b)(iii)(A), in determining whether any issued rights, options or warrants entitle the holders of the Common Stock 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 each Trading Day in the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate
offering price of such shares of Common Stock, there shall be taken into account any consideration that the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if
other than cash, to be determined by the Board of Directors. 
 (c) Other Distributions. 

(i) If the Ex-Dividend Date occurs for a distribution by the Company of shares of its Capital Stock, evidences of its
indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities to all or substantially all holders of the Common Stock, excluding (A) dividends or distributions (including
subdivisions) and rights, options or warrants, in each case, for which an adjustment is made pursuant to Sections 11.05(a) or 11.05(b); (B) dividends or distributions paid exclusively in cash for which an adjustment is made pursuant to
Section 11.05(d); and (C) Spin-Offs for which an adjustment is made pursuant to Section 11.05(c)(ii) (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire
Capital Stock or other securities, the “Distributed Property”), 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 for such distribution;
		
	CR1 =	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;


  
 60 










			
		
	SP0 =	  	the average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such distribution; and
		
	FMV =	  	the fair market value, as determined by the Board of Directors, of the Distributed Property distributed with respect to each outstanding share of the Common Stock as of the Open of
Business on the Ex-Dividend Date for such distribution.

 Notwithstanding the foregoing, if “SP0” (as defined above) minus “FMV” (as defined above) is
less than $1.00, in lieu of the foregoing adjustment, each Holder shall receive, for each $1,000 principal amount of Notes held, at the same time and upon the same terms as holders of the Common Stock, the kind and amount of Distributed Property
that such Holder would have received as if such Holder had owned a number of shares of the Common Stock equal to the Conversion Rate in effect on the record date for such distribution. 

Any adjustment made under this Section 11.05(c)(i) shall become effective immediately after the Open of Business on the Ex-Dividend
Date for such distribution. If such distribution is not so paid or made, or if any rights, options or warrants are not exercised before their expiration date, the Conversion Rate shall be readjusted, as of the date the Board of Directors determines
not to make or pay such distribution or as of such expiration date, as the case may be, to be the Conversion Rate that would then be in effect had such distribution not been declared or to the extent such rights or warrants are not exercised, as
applicable. 
 (ii) With respect to an adjustment pursuant to this Section 11.05(c), if the relevant
dividend or other distribution consists of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company that are listed for trading or quoted (or will be listed or
quoted upon consummation of the spin-off) on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

 
 



 
 where: 
  

			
		
	CR0 =	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for the Spin-Off;
		
	CR1 =	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off;
		
	FMV0 =	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to a holder of one share of the Common Stock (determined by reference to the
definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first ten consecutive Trading Day period immediately following, and
including, the effective date for the Spin-Off (such period, the “Valuation Period”); and


  
 61 










			
		
	MP0 =	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 Notwithstanding the foregoing, (A) if the last VWAP Trading Day of the Observation Period for any
conversion to which Cash Settlement or Combination Settlement applies occurs on or after the effective date for the Spin-Off, but less than ten Trading Days immediately following, and including, the effective date for the Spin-Off, references within
this Section 11.05(c)(ii) to ten Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Conversion Values or Daily Settlement Amounts, as the case may be, in respect of that conversion, with such lesser number of
Trading Days as have elapsed from, and including, the effective date for the Spin-Off to, and including, the last VWAP Trading Day of such Observation Period, and (B) for purposes of determining the Conversion Rate applicable to any conversion
for which the Conversion Date occurs during the ten Trading Days commencing on the effective date for any Spin-Off, references within this Section 11.05(c)(ii) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days
as have elapsed from, and including, the effective date for such Spin-Off to, but excluding, the relevant Conversion Date. 

Any adjustment made pursuant to this Section 11.05(c)(ii) shall become effective as of the Open of Business on the Ex-Dividend Date
for the Spin-Off. If such Spin-Off is subsequently cancelled and does not become effective, the Conversion Rate shall be readjusted, as of the date of such cancellation, to be the Conversion Rate that would have been in effect if such Spin-Off had
not been declared. 
 For purposes of this Section 11.05(c) (and subject in all respect to Section 11.05(i)), rights,
options or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which
rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (A) are deemed to be transferred with such shares of the Common Stock; (B) are not exercisable; and (C) are also
issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 11.05(c) (and no adjustment to the Conversion Rate under this Section 11.05(c) will be required) until the
occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 11.05(c).
If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to
purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants
with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of
rights, options or warrants, or any Trigger Event or other event (of the type described in the 

  
 62 









 
immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this
Section 11.05(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate
shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though
it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants),
made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate
shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of Section 11.05(a),
Section 11.05(b) and this Section 11.05(c), if any dividend or distribution to which this Section 11.05(c) is applicable also includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which Section 11.05(a) is applicable (the “Clause A Distribution”); or 

(B) a dividend or distribution of rights, options or warrants to which Section 11.05(b) is applicable (the “Clause B
Distribution”), 
 then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B
Distribution, shall be deemed to be a dividend or distribution to which this Section 11.05(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 11.05(c) with respect to
such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 11.05(a) and
Section 11.05(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date
of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date or
effective date” within the meaning of Section 11.05(a) or “outstanding immediately prior to the Open of Business on such Ex-Dividend Date” within the meaning of Section 11.05(b). 

(d) Adjustment for Cash Distributions. If the Ex-Dividend Date occurs for any cash dividend or distribution by the Company to all
or substantially all holders of the outstanding Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  





 
 where: 

  
 63 










			
		
	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 average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such dividend or distribution; and
		
	C =	  	the amount in cash per share that the Company pays or distributes to holders of the Common Stock.

 If “SP0” (as defined above) minus “C” (as defined above) is less than $1.00, in lieu of the foregoing adjustment,
each Holder shall receive, for each $1,000 principal amount of Notes held, at the same time and upon the same terms as holders of the Common Stock, the amount of cash such Holder would have received if such Holder had owned a number of shares of the
Common Stock equal to the Conversion Rate in effect on the record date for such distribution. 
 Any adjustment made under this
Section 11.05(d) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be readjusted, as of the date the Board of
Directors determines not to make or pay such distribution, to be the Conversion Rate that would then be in effect had the related Ex-Dividend Date not occurred. 
 (e) Adjustment for Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries makes a payment to holders of the Common Stock in respect of a tender offer or exchange offer for the
Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period
commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “Expiration Date”), 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 Expiration Date;
		
	CR1 =	  	the Conversion Rate in effect immediately after the Close of Business on the Expiration Date;


  
 64 










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

 The adjustment to the Conversion Rate under this Section 11.05(e) shall be given effect at the Close
of Business on the Expiration Date. If the Expiration Date is less than ten Trading Days prior to, and including, the last VWAP Trading Day of the Observation Period in respect of any conversion to which Cash Settlement or Combination Settlement
applies, references within this Section 11.05(e) to ten Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Conversion Values or Daily Settlement Amounts, as the case may be, in respect of that conversion, with
such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last VWAP Trading Day of such Observation Period. For purposes of determining the Conversion Rate
applicable to any conversion during the ten Trading Day period commencing on the Trading Day next succeeding the Expiration Date, references within this Section 11.05(e) to ten Trading Days shall be deemed replaced with such lesser number of
Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but excluding, the relevant Conversion Date. 
 (f) Holder Participation in Adjustment Events. Notwithstanding the provisions set forth in clauses (a) through (e) above, if any adjustment to the Conversion Rate pursuant to such
provisions becomes effective on any Ex-Dividend Date or effective date and a Holder that has converted its Notes would (i) receive shares of Common Stock based on an adjusted Conversion Rate and (ii) be a record holder of such shares of
Common Stock on the record date for the dividend, distribution or event giving rise to such adjustment, then, in lieu of receiving shares of Common Stock at such an adjusted Conversion Rate, such Holder shall receive a number of shares of Common
Stock, if any, upon conversion based on an unadjusted Conversion Rate and shall participate in the related dividend, distribution or other event giving rise to such adjustment. 

(g) Adjustments Not Yet Effective. If, in the case of any conversion of a Note to which Combination Settlement applies, on any
VWAP Trading Day during the Observation Period corresponding to the Conversion Date for such Note, shares of Common Stock are deliverable as part of the Daily Settlement Amount for such VWAP Trading Day, and 

  
 65 









 (i) the record date for any dividend or distribution, the effective date for
any share split or combination or the Expiration Date for any tender or exchange offer by the Company that, in each case, would require an adjustment to the Conversion Rate pursuant to Section 11.05(a), (b), (c), (d) or (e) occurs
prior to the Company’s delivery of such shares of Common Stock to the converting Holder; 
 (ii) the
applicable Conversion Rate for such VWAP Trading Day will not reflect such adjustment; and 
 (iii) the shares of
Common Stock that the Company shall deliver to the converting Holder with respect to such VWAP Trading Day are not entitled to participate in the relevant event (because such shares were not held by such Holder on the related record date, effective
date, expiration date or otherwise), 
 then the Company shall adjust the number of shares of Common Stock deliverable to such Holder as part of
the Daily Settlement Amount for such VWAP Trading Day in a manner that appropriately reflects the relevant distribution, transaction or event. 
 (h) Other Adjustments. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices over a span of multiple days, the Company shall make appropriate
adjustments to such prices to account for any adjustment to the Conversion Rate that becomes effective, or any event that would require an adjustment to the Conversion Rate where the Ex-Dividend Date, effective date or Expiration Date of the event
occurs, at any time during the period over which such Last Reported Sale Prices are to be calculated. 
 (i) Rights
Plans. To the extent that the Company has a rights plan in effect upon conversion of any Note, each share of Common Stock issued upon such conversion (x) shall be entitled to receive the number of rights, if any, associated with one share
of Common Stock under such rights plan, and (y) shall, if issued in certificated form, bear such legends, if any, as may be required under such rights plan; provided, however, that if prior to the Conversion Date for such Note,
the rights have separated from the Common Stock in accordance with the provisions of the applicable rights plan, the converting Holder shall not be entitled to receive such rights upon conversion, and at the time of such separation, the Conversion
Rate shall be adjusted in accordance with Section 11.05(c) as if the Company made a distribution of Distributed Property to the holders of the Common Stock; provided, further, that such adjustment shall be subject to readjustment
upon the expiration, termination or redemption of such separated rights in accordance with Section 11.05(c). 
 (j)
[Reserved]. 
 (k) Voluntary Increases. In addition to those adjustments required by clauses (a), (b), (c),
(d) and (e) of this Section 11.05, and to the extent permitted by applicable law and any applicable stock exchange rules, from time to time, (i) the Company may increase the Conversion Rate of the Notes by any amount for a period
of at least 20 Business Days if the Board of Directors determines that such increase would be in the best interest of the Company and (ii) the Company may (but is not required to) increase the Conversion Rate to avoid or


  
 66 









 
diminish income tax to holders of the Common Stock or rights to purchase shares of the Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or a
similar event; provided that the Company shall not take any action that would result in adjustment of the Conversion Rate, pursuant to this Section 11.05(k), that would result in a reduction of the Conversion Price to less than the par
value per share of the Common Stock. 
 (l) No Other Adjustments. Except as expressly stated herein, the Conversion Rate
shall not be subject to adjustment as a result of any issuance of shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable
securities. 
 (m) No Decreases in the Conversion Rate. Notwithstanding anything to the contrary in clauses
(a) through (e) above, if the application of the formulas set forth therein 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; provided that in the case of an increase in the Conversion Rate in connection with any Spin-Off, distribution on the Common Stock or issuance of rights, options or warrants to holders of Common Stock, such increase may be
reversed, to the extent expressly set forth herein, on account of the cancellation of such Spin-Off, such distribution not being paid or made or the expiration of such rights, options or warrants. 

(n) Notice of Certain Potential Events. In connection with any event that will require an adjustment to the Conversion Rate
pursuant to this Section 11.05 or any Share Exchange Event or any event or transaction described in Section 6.01 (unless prior notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall,
at least 30 Scheduled Trading Days prior to the anticipated occurrence or effective date of such event or transaction, mail to the Holders a notice of such transaction or event describing the event, the anticipated occurrence or effective date, as
the case may be, the methodology for determining the relevant adjustment (if applicable) to the Conversion Rate or other terms of the Notes and such other information as the Company reasonably determines is appropriate to include. 

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

 Section 11.06. Effect of Reclassification, Consolidation, Merger or Sale.  

  
 67 









 (a) In the case of: 

(i) any recapitalization, reclassification or change of the Common Stock (other than a change resulting from a subdivision
or combination for which an adjustment is provided pursuant to Section 11.05); 
 (ii) any consolidation,
merger, combination or similar transaction involving the Company; 
 (iii) any sale, lease or other transfer to a
third party of substantially all of the consolidated assets of the Company and its Subsidiaries; or 
 (iv) any
statutory share exchange, 
 in each case, as a result of which the Common Stock will be converted into, or exchanged for, stock, other
securities or other property or assets (including cash or any combination thereof) (any such event, a “Share Exchange Event” and any such stock, other securities or other property or assets, “Reference Property,”
and the amount of Reference Property that a holder of one share of the Common Stock immediately prior to such Share Exchange Event would have been entitled to receive upon the occurrence of such Share Exchange Event, a “Unit of Reference
Property”), then the Company or the successor or purchasing company, as the case may be, shall execute a supplemental indenture providing that, at and after the effective time of such Share Exchange Event, the Notes shall become convertible
into Units of Reference Property; provided that, at and after the effective time of such Share Exchange Event, (x) prior to obtaining Stockholder Approval, for each share of Common Stock that the Company would otherwise be obligated to
deliver with respect to such conversion, the Company shall instead deliver a Unit of Reference Property and (y) after obtaining Stockholder Approval prior to the relevant Conversion Date, the amount of cash (if any) and the number of Units of
Reference Property (if any) that the Company shall deliver upon conversion of a Note shall be determined pursuant to Section 11.03 (and the definitions referenced therein), except that for any VWAP Trading Day during the relevant Observation
Period in the case of Cash Settlement or Combination Settlement (A) the Daily VWAP for such VWAP Trading Day shall be calculated based on the value of a Unit of Reference Property on such VWAP Trading Day and (B) in lieu of each share of
Common Stock that the Company would otherwise be obligated to deliver on such VWAP Trading Day, the Company shall deliver a Unit of Reference Property. 
 If a Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of
stockholder election), then (i) the Reference Property shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (ii) the Unit
of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall notify Holders, the Trustee and the Conversion
Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. 
 Such
supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments provided for in this Article 11. If the Reference
Property in respect of any Share 

  
 68 









 
Exchange Event includes shares of stock, securities or other property or assets of a Person other than the Company or, in the case of a transaction described in Article 6, the Successor Company,
then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes, including the right of Holders to require the Company to purchase their
Notes upon a Fundamental Change pursuant to Article 3, as the Board of Directors shall reasonably consider necessary by reason of the foregoing. 
 (b) If the Company executes a supplemental indenture pursuant to this Section 11.06, as promptly as practicable, the Company shall file with the Trustee an Officer’s Certificate briefly
describing such Share Exchange Event, the composition of a Unit of Reference Property for such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent to such Share Exchange Event under this Indenture
have been complied with. Any failure to deliver such Officer’s Certificate shall not affect the legality or validity of such supplemental indenture. The Company shall also issue a press release containing such information and shall make such
press release available on its website. 
 (c) The Company shall not become a party to any Share Exchange Event unless its terms
are consistent with this Section 11.06. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes as set forth in Section 11.02 and Section 11.01 prior to the effective date of such Share
Exchange Event. 
 (d) The provisions of this Section 11.06 shall apply successively to successive Share Exchange Events.

 Section 11.07. Adjustment to Conversion Rate Upon Certain Transactions.  

(a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Note in connection with such Make-Whole Fundamental
Change, the Company shall, in the circumstances described in this Section 11.07, increase the Conversion Rate for such Note by the number of additional shares of Common Stock (the “Additional Shares”) determined under this
Section 11.07. For the purposes of this Section 11.07, a conversion of Notes shall be deemed to be “in connection with” a Make-Whole Fundamental Change if the Conversion Date occurs during the period beginning on, and including,
the date on which such Make-Whole Fundamental Change occurs or becomes effective (such date, the “Make-Whole Fundamental Change Effective Date”) and ending on, and including, the Business Day immediately preceding the earliest of
(i) the 35th Scheduled Trading Day immediately following the later of (x) the Make-Whole Fundamental Change Effective Date and (y) June 30, 2013, (ii) the related Fundamental Change Purchase Date, if such Make-Whole
Fundamental Change is also a Fundamental Change and the effective date therefor occurs after June 30, 2013, and (iii) the Business Day immediately preceding the Maturity Date. The Company shall notify Holders within one Business Day after
the first public announcement by the Company or a third party of an event or transaction that the Company reasonably determines would, if consummated, constitute a Make-Whole Fundamental Change. Upon receiving notice or otherwise becoming aware of a
potential Make-Whole Fundamental Change, the Company shall use commercially reasonable efforts to announce or cause the announcement of such potential Make-Whole Fundamental Change in time to deliver such notice at least 35 Scheduled Trading Days
prior to the anticipated Make-Whole Fundamental Change Effective Date. 

  
 69 









 (b) The number of Additional Shares by which the Conversion Rate shall be increased for a
Note converted in connection with a Make-Whole Fundamental Change shall be determined by reference to the table in clause (d) below, based on the relevant Make-Whole Fundamental Change Effective Date and the stock price paid (or deemed paid) in
the Fundamental Change, as determined pursuant to clause (e) below (such stock price, the “Stock Price”). 

(c) The Stock Prices set forth in the column headings of the table in clause (d) below shall be adjusted as of any date on which the
Conversion Rate is adjusted pursuant to Section 11.05. The adjusted Stock Prices shall equal the Stock Prices in effect immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate in effect
immediately prior to the adjustment giving rise to the Stock Price adjustment, and the denominator of which is the Conversion Rate in effect immediately after such adjustment. The number of Additional Shares set forth in the table in clause
(d) below shall be adjusted at the same time and in the same manner as the Conversion Rate is adjusted pursuant to Section 11.05. 
 (d) The following table sets forth the number of Additional Shares by which the Conversion Rate will be increased for a Holder that converts its Note in connection with a Make-Whole Fundamental Change
having any Make-Whole Fundamental Change Effective Date and Stock Price set forth therein:

 In the event that the exact Stock Price or Make-Whole Fundamental Change Effective Date for a Make-Whole Fundamental
Change is not set forth in the table above: 
 (i) if the Stock Price is between two prices listed in the table
or the Make-Whole Fundamental Change Effective Date is between two Make-Whole Fundamental Change Effective Dates listed in the table, the applicable 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 Make-Whole Fundamental Change Effective Dates based on a 365-day year, as applicable; 

(ii) if the Stock Price is greater than $100.00 (subject to adjustment in the same manner and at the same time as the
Stock Prices listed in the table), no Additional Shares shall be added to the Conversion Rate; and 

  
 70 









 (iii) if the Stock Price is less than $15.47 (subject to adjustment in the
same manner and at the same time as the Stock Prices listed in the table), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding anything to the contrary in this Section 11.07, in no event shall the Conversion Rate exceed 64.6412 shares per $1,000 principal amount of Notes, subject to adjustment at the same
time and in the same manner as the Conversion Rate pursuant to Section 11.05 (the “Maximum Conversion Rate”). 
 (e) With respect to any Make-Whole Fundamental Change: 
 (i) that
is described in clause (2) of the definition Fundamental Change and in which the holders of Common Stock receive only cash in consideration for their shares (a “Cash Merger”), notwithstanding anything to the contrary in
Section 11.03, the Company shall satisfy its Conversion Obligation with respect to any Note converted at any time following such Cash Merger by delivering to the converting Holder, on the third Business Day immediately following the Conversion
Date for such Note, an amount of cash, for each $1,000 principal amount of such Note converted, equal to the product of (A) the Conversion Rate in effect on such Conversion Date (as increased by any Additional Shares pursuant to this
Section 11.07) and (B) the “Stock Price” with respect to such Cash Merger, which shall be the cash amount per share paid to holders of Common Stock in such Cash Merger; or 

(ii) that is not a Cash Merger, (A) the “Stock Price” with respect to such Make-Whole Fundamental Change
shall equal the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the related Make-Whole Fundamental Change Effective Date, and (B) for
the avoidance of doubt, the Company shall satisfy its Conversion Obligation with respect to any Note converted in connection with such Make-Whole Fundamental Change in accordance with Section 11.03, based on the Conversion Rate as increased by
any Additional Shares pursuant to this Section 11.07. 
 Section 11.08. Trustee’s Disclaimer. None of the
Trustee, Registrar, Paying Agent, Conversion Agent or the Bid Solicitation Agent shall have any duty to determine when an adjustment under this Article 11 should be made, how it should be made or what it should be. None of the Trustee, Registrar,
Paying Agent, Conversion Agent or Bid Solicitation Agent shall be responsible for determining whether any of a Fundamental Change, a Make-Whole Fundamental Change, a VWAP Market Disruption Event, a Trigger Event or a Share Exchange Event shall have
occurred. None of the Trustee, the Registrar, the Paying Agent, Conversion Agent or the Bid Solicitation Agent shall have any shall be accountable for and makes any representation as to the validity or value (of the kind or amount) of any shares of
Common Stock, of any Reference Property or of any other securities, property or assets issued upon conversion of Notes. None of the Trustee, the Registrar, the Paying Agent, Conversion Agent or the Bid Solicitation Agent shall be responsible for
(i) any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of Common Stock or stock or share certificates or other securities or property upon the surrender of any Note for the purpose of conversion and
(ii) the Company’s failure to comply with this Article 11. 

  
 71 









 None of the Trustee, Registrar, Paying Agent, Conversion Agent or Bid Solicitation Agent
(except for the Bid Solicitation Agent in respect of the calculation of the Trading Price as and to the extent provided in Section 11.01) shall be responsible for calculating the Trading Price, or determining whether any event contemplated by
Section 11.01 has occurred which makes the Notes eligible for conversion, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed herein, in making the same and shall be
entitled to presume that no such event has occurred until the Company has delivered to the Trustee an Officer’s Certificate stating that such event has occurred, on which Officer’s Certificate the Trustee may conclusively rely, and the
Company agrees to deliver such Officer’s Certificate to the Trustee and any such agent immediately after the occurrence of any such event. 
 Without limiting the generality of the foregoing, none of the Trustee, Registrar, Paying Agent, Conversion Agent or Bid Solicitation Agent shall be under any responsibility to determine the correctness of
any provisions contained in any supplemental indenture entered into pursuant to Section 10.01(c) relating either to the kind or amount of shares of stock or securities or other property or assets (including cash) receivable for Holders upon the
conversion of their Notes after any Share Exchange Event or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.01, may accept as conclusive evidence of the correctness of any such provisions, and
shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 

Each Conversion Agent and Bid Solicitation Agent (if other than the Company) shall have the same protection under this Section 11.08
as the Trustee, the Registrar and the Paying Agent. 
 ARTICLE 12 

PAYMENT OF INTEREST 
 Section 12.01. Payment of Interest. The Company shall pay interest on the Notes at a rate of 4.25% per annum, payable semi-annually in arrears on April 1 and October 1 of each
year (each, an “Interest Payment Date”) or, if any such day is not a Business Day, the immediately following Business Day, commencing October 1, 2013. Interest on the Notes shall accrue from the most recent date to which
interest has been paid or duly provided for, or, if no interest has been paid, the Original Issuance Date. Interest on a Note shall be paid to the Holder of record of such Note at the Close of Business on the March 15 or September 15,
whether or not a Business Day (each, a “Record Date”), immediately preceding the April 1 or October 1 Interest Payment Date, respectively, and shall be computed on the basis of a 360-day year composed of twelve 30-day
months. 
 Section 12.02. Defaulted Interest. Any installment of interest that is payable, but is not punctually
paid or duly provided for on any Interest Payment Date (“Defaulted Interest”), shall forthwith cease to be payable to the Holders in whose names the Notes were registered on the Record Date applicable to such installment of
interest. Defaulted Interest (including any interest on such Defaulted Interest) may be paid by the Company, at its election, as provided in Sections 12.02(a) or 12.02(b). 

  
 72 









 (a) The Company may elect to make payment of any Defaulted Interest (including any interest
on such Defaulted Interest) to the Holders in whose names the Notes are registered at the Close of Business on a special record date for the payment of such Defaulted Interest (a “Special Record Date”), which shall be fixed in the
following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal
to the aggregate amount proposed to be paid in respect of such Defaulted Interest (including any interest on such Defaulted Interest) or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment,
such money when deposited to be held in trust for the benefit of the Holders entitled to such Defaulted Interest (including any interest on such Defaulted Interest) as provided in this Section 12.02(a). Thereupon the Trustee shall fix a Special
Record Date for the payment of such Defaulted Interest (including any interest on such Defaulted Interest), which shall be not more than 15 calendar days and not less than ten calendar days prior to the date of the proposed payment and not less than
ten calendar days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the
proposed payment of such Defaulted Interest (including any interest on such Defaulted Interest) and the Special Record Date therefor to be sent by first-class mail, postage prepaid, to each Holder at such Holder’s address as it appears in the
registration books of the Registrar, not less than ten calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest (including any interest on such Defaulted Interest) and the Special Record Date
therefor having been mailed as aforesaid, such Defaulted Interest (including any interest on such Defaulted Interest) shall be paid to the Holders in whose names the Notes are registered at the Close of Business on such Special Record Date and shall
no longer be payable pursuant to Section 12.02(b). 
 (b) Alternatively, the Company may make payment of any Defaulted
Interest (including any interest on such Defaulted Interest) in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange if,
after notice given by the Company to the Trustee of the proposed payment pursuant to this Section 12.02(b), such manner of payment shall be deemed practicable by the Trustee. 

Section 12.03. Interest Rights Preserved. Subject to the foregoing provisions of this Article 12 and, to the extent
applicable, Sections 2.06 and 2.07, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by
such other Note.

 Section 13.02.
Call of Meetings by Trustee. The Trustee may at any time call a meeting of Holders to take any action specified in Section 13.01, to be held at such time and at such place as the Trustee shall determine. Notice of every meeting of the
Holders, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting and the establishment of any record date pursuant to Section 1.04, shall be mailed to Holders of such Notes at
their addresses as they shall appear on the Register. Such notice may also be mailed to the Company. Such notices shall be mailed not less than twenty nor more than sixty days prior to the date fixed for the meeting. 

Any meeting of Holders shall be valid without notice if the Holders of all Notes then outstanding are present in person or by proxy or if
notice is waived before or after the meeting by the Holders of all Notes then outstanding, and if the Company and the Trustee are either present by duly authorized representatives or have, before or after the meeting, waived notice (in the case of
the Company, to the extent such notice was required hereunder). 
 Section 13.03. Call of Meetings by Company or
Holders. In case at any time the Company, pursuant to a Board Resolution, or the Holders of at least 10% of the aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Holders, by written
request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within 20 days after receipt of such request, then the Company or such Holders may determine
the time and the place for such meeting and may call such meeting to take any action authorized in Section 13.01, by mailing notice thereof as provided in Section 13.02. 

Section 13.04. Qualifications for Voting. To be entitled to vote at any meeting of Holders a Person shall (a) be a

entitled to be present or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company and its counsel.

 Section 13.05. Regulations. Notwithstanding any other provisions of this Indenture, the Trustee may make such
reasonable regulations as it may deem advisable for any meeting of Holders, in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 
 The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders as provided in Section 13.03, in
which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Holders of a majority in
principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 
 Subject to the provisions of
Section 2.08, at any meeting of Holders each Holder or proxyholder shall be entitled to one vote for each $1,000 principal amount of Notes held or represented by him or her; provided, however, that no vote shall be cast or counted
at any meeting in respect of any Note challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in
writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 13.02 or Section 13.03 may be adjourned from time to time by the Holders of
a majority of the aggregate principal amount of Notes represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice. 

Section 13.06. Voting. The vote upon any resolution submitted to any meeting of Holders shall be by written ballot on which
shall be subscribed the signatures of the Holders or of their representatives by proxy and the outstanding principal amount of the Notes held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of the
proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more
Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 13.02. The record shall show the principal amount of the Notes voting in favor of or against
any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company, if appropriate, and the other to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 

  
 75 









 Any record so signed and verified shall be conclusive evidence of the matters therein
stated. 
 Section 13.07. No Delay of Rights by Meeting. Nothing contained in this Article 13 shall be deemed or
construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to

 [FORM OF REVERSE OF NOTE] 

BLUCORA, INC. 

This Note is one of a duly authorized issue of Notes of the Company, designated as its 4.25% Convertible Senior Notes due 2019 (the
“Notes”), limited to the aggregate principal amount of $201,250,000 all issued or to be issued under and pursuant to an Indenture dated as of March 15, 2013 (the “Indenture”), between the Company and The Bank
of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. 

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all
Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions
and certain exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will
make all payments and deliveries in respect of the Fundamental Change Purchase Price on the Fundamental Change Purchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to
collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

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

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

Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with
payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the
old Notes surrendered for such exchange. The Trustee (or, if applicable, such other entity appointed as Registrar in accordance with the terms of the Indenture) need not transfer or exchange any Notes in respect of which a Fundamental Change
Purchase Notice has been given and not withdrawn (except, in the case of a Note to be repurchased in part, the portion of the Note not to be repurchased). 
 The Notes shall be redeemable at the Company’s option in accordance with the terms and conditions specified in the Indenture. 
 Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Notes or any portion thereof (in
principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Purchase Date at a price equal to the Fundamental Change Purchase Price. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the
Close of Business on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into shares of Common Stock or, following Stockholder Approval, cash, shares of
Common Stock or a combination thereof, based on the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 
 Terms used in this Note and defined in the Indenture are used herein as therein defined.
