expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and to the Company. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the “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.

fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the 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 Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the
outstanding Securities 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 SECURITIES 
 Section 2.01 Form and Dating. The Securities
and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is a part of this Indenture. The Securities 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 Security shall be dated
the date of its authentication. Except as otherwise expressly permitted in this Indenture, all Securities shall be identical in all respects. Notwithstanding any differences among them, all Securities issued under this Indenture shall vote and
consent together on all matters as one class. 
 (a) Initial Securities. The Securities shall be issued initially in the
form of a Global Security, which shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the Depositary (as defined below) and registered in the name of The Depository Trust Company (“DTC”) or the nominee
thereof (DTC, or any successor thereto, and any such nominee being hereinafter referred to as the “Depositary”), duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount
of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary as hereinafter provided. 
 (b) Global Securities in General. Each Global Security shall represent such of the outstanding Securities as shall be specified therein and each shall provide that it shall represent the aggregate
principal amount of outstanding Securities from time to time endorsed thereon and that the aggregate principal amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges,
repurchases and conversions. 
 (c) Any adjustment of the aggregate principal amount of a Global Security to reflect the amount
of any increase or decrease in the amount of outstanding Securities 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 (including Additional Interest), if any, and any payment of the Fundamental Change Repurchase Price or premium on the Global Security shall be made to the
Holder of such Security on the date of payment, unless a Record Date or other means of determining Holders eligible to receive payment is provided for herein. 
 (d) Book-Entry Provisions. This Section 2.01(d) shall apply only to Global Securities deposited with or on behalf of the Depositary. 

The Company shall execute and the Trustee shall, in accordance with this Section 2.01(d), authenticate and deliver initially one or
more Global Securities that (a) shall be registered in the name of the Depositary, (b) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions and (c) shall bear the legends substantially
to the effect of those required by Section 2.01(e). 

  
 9 








 (e) Legends. Each Global Security shall bear the Global Securities Legend set forth
in Exhibit A. 
 Section 2.02 Execution and Authentication. The Securities shall be executed on behalf of the Company by
any Officer. The signature of the Officer on the Securities may be manual or facsimile. 
 If an Officer whose signature is on a
Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless. 
 At any time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a written order of the Company
in the form of an Officers’ Certificate for the authentication and delivery of such Securities, and the Trustee, in accordance with such written order of the Company, shall authenticate and deliver such Securities. 

A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the
Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
 The
Securities 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 shall initially authenticate and deliver Securities for original issuance in an aggregate principal amount of [$200,000,000], upon receipt of one or more Company Orders. The Trustee shall
authenticate and deliver Securities for original issuance in an additional aggregate principal amount of up to [$30,000,000], upon receipt of one or more Company Orders upon exercise of the option granted to the initial purchasers of the Securities
described in the Prospectus (the “Option Securities”). The aggregate principal amount of the Securities that initially may be authenticated and delivered under this Indenture (the “Initial Securities”) shall be
limited to $[230,000,000] subject to increase as set forth in Section 2.14. 
 The Trustee may appoint authenticating
agents. The Trustee may at any time after the execution of this Indenture appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so,
except any Securities 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 2.03 Registrar, Paying Agent and
Conversion Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”), an office or agency in the Borough of Manhattan, City of New York,
where Securities may be presented for payment (“Paying Agent”), an office or agency where Securities may be presented for conversion (“Conversion Agent”) and an office or agency where notices to or upon the Company
in respect of the Securities 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 Securities, the Securities held by each Holder and the transfer,


  
 10 









 
exchange and conversion of Securities (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 additional paying agent, including any named pursuant to Section 4.05. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 4.05. 

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 shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the
Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee may agree to act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar, Conversion Agent or co-registrar. 
 The Company
initially appoints the Trustee as the Paying Agent, the Conversion Agent, and the Registrar, in connection with the Securities, and the office of [•] at [ADDRESS], Attention: [•], 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. 

Section 2.04 Paying Agent to Hold Money and Securities in Trust. Except as otherwise provided herein, on or prior to each due
date of payment in respect of any Security, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds if deposited on the due date) or Common Stock or, as permitted by this Indenture, a combination thereof,
sufficient to make such payments when so becoming due. The Paying Agent shall (or, if the Paying Agent is not a party hereto, the Company shall require each Paying Agent to agree in writing that such Paying Agent shall) hold in trust for the benefit
of Holders or the Trustee all money and Common Stock held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any default by the Company in making any such payment. At any time during the
continuance of any such default, the Paying Agent (if not the Trustee) shall, upon the written request of the Trustee, forthwith pay to the Trustee all money and Common Stock so held in trust. If the Company or a Wholly Owned Subsidiary acts as
Paying Agent, it shall segregate the money and Common Stock held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money and Common Stock held by it to the Trustee and to
account for any funds and Common Stock disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee. 

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, in writing at least five Business Days before each Interest Payment 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. 

  
 11 









 Section 2.06 Transfer and Exchange. 

(a) Subject to Section 2.12 hereof, upon surrender for registration of transfer of any Security, together with a written instrument
of transfer satisfactory to the Registrar duly executed by the Holder or such Holder’s attorney duly authorized in writing, at the office or agency of the Company designated as the Registrar or co-Registrar pursuant to Section 2.03,
(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 Securities 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 2.03 regarding the designated transferee or
transferees in the Register. The Company shall not charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be
imposed in connection with the registration of, transfer or exchange of the Securities from the Holder requesting such transfer or exchange. 
 At the option of the Holder, Securities may be exchanged for other Securities of any authorized denomination or denominations, of a like aggregate principal amount, upon surrender of the Securities to be
exchanged, 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 such office or agency and documents of identity and title
satisfactory to Registrar. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities 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 Securities in respect of which a Fundamental Change Repurchase Notice has been given and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Securities to be
repurchased in part, the portion thereof not to be repurchased). 
 (b) Notwithstanding any provision to the contrary herein, so
long as a Global Security remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Security, 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 Security shall be limited to transfers of such Global Security, 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 2.03 hereof shall
provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 

  
 12 









 (e) No Registrar shall be required to make registrations of transfer or exchange of
Securities during any periods designated in the text of the Securities or in this Indenture as periods during which such registration of transfers and exchanges need not be made. 

Section 2.07 Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security
claims that such Security has been lost, destroyed or stolen and the Holder provides evidence of the loss, theft or destruction satisfactory to the Company and the Trustee, the Company shall issue and the Trustee shall authenticate a replacement
Security 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 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 Security is replaced. The Company and
the Trustee may charge the Holder for their expenses in replacing a Security. 
 Upon the issuance of any new Securities 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 Security issued pursuant to this Section 2.07 in exchange for any mutilated Security, or in lieu of
any destroyed, lost or stolen Security, shall constitute an original additional contractual obligation of the Company and any other obligor upon the Securities, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
 Section 2.08 Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation
and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security; provided, however, that in determining whether the
Holders of the requisite principal amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent, waiver or other action hereunder, Securities owned by the Company or any obligor upon the Securities
or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction,
notice, consent, waiver or other action, only Securities which a Trust Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be
considered in any such determination (including, without limitation, determinations pursuant to Articles 6 and 9). 
 If a
Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser. 

  
 13 









 If the Paying Agent holds, in accordance with this Indenture, on a Fundamental Change
Repurchase Date or on the Maturity Date, money sufficient to pay Securities payable on that date, then immediately after such Fundamental Change Repurchase Date or Maturity Date, as the case may be, such Securities shall cease to be outstanding and
interest (including Additional Interest), if any, on such Securities shall cease to accrue and such Securities shall cease to be convertible. 
 If a Security is converted in accordance with Article 10, then from and after the time of conversion on the Conversion Date, such Security shall cease to be outstanding and interest (including Additional
Interest), if any, shall cease to accrue on such Security. 
 Section 2.09 Temporary Securities. Until definitive
Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities. 

Section 2.10 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and
the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment
or cancellation and shall dispose of such cancelled Securities in its customary manner. The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant
to Article 10. 
 Section 2.11 Persons Deemed Owners. Prior to due presentment of a Security 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 Security is registered in the Register as the owner of such Security for the purpose of receiving payment of principal, interest
(including Additional Interest), if any, and any payment of the Fundamental Change Repurchase Price or premium thereon, for the purpose of conversion and for all other purposes whatsoever, whether or not such Security 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 Securities. 
 (a) Notwithstanding any other provisions of this Indenture or the Securities, (A) transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.06 and
Section 2.12(a)(i), (B) transfers of a beneficial interest in a Global Security for a Certificated Security shall comply with Section 2.06 and Section 2.12(a)(ii) below, and (C) transfers of a Certificated Security
shall comply with Section 2.06 and 2.12(a)(iii) and (iv) below. Any such transfer shall comply with the Applicable Procedures to the extent so required. 

(i) Transfer of Global Security. A Global Security may not be transferred, in whole or in part, to any Person other
than the Depositary or a nominee or any successor 

  
 14 









 
thereof, and no such transfer to any such other Person may be registered; provided that this clause (i) shall not prohibit any transfer of a Security that is issued in exchange for a
Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security 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 Security effected in accordance with the other provisions of this Section 2.12(a). 

(ii) Restrictions on Transfer of a Beneficial Interest in a Global Security for a Certificated Security. A
beneficial interest in a Global Security may not be exchanged for a Certificated Security except: 
 (A)
Certificated Securities shall be issued to all owners of beneficial interests in a Global Security in exchange for such interests if: 
 (1) DTC notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security and a successor Depositary is not appointed by the Company within 90 days of such notice; or

 (2) the Company, at any time, in its sole discretion, executes and delivers to the Trustee and the Registrar
an Officers’ Certificate stating that the entire Global Security shall be so exchangeable. 
 In connection with the
exchange of an entire Global Security for Certificated Securities pursuant to this Subsection (ii), such Global Security 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 Security, an equal aggregate principal amount of Certificated Securities of authorized denominations.

 (B) The owner of a beneficial interest in a Global Security will be entitled to receive a Certificated
Security in exchange for such interest if an Event of Default has occurred and is continuing. 
 Upon receipt by the Registrar
of instructions from the Holder of a Global Security directing the Registrar to (x) issue one or more Certificated Securities in the amounts specified to the owner of a beneficial interest in such Global Security and (y) debit or cause to
be debited an equivalent amount of beneficial interest in such Global Security, subject to the Applicable Procedures: 
 1) the
Registrar shall notify the Company and the Trustee of such instructions, identifying the owner and amount of such beneficial interest in such Global Security; 
 2) the Company shall promptly execute, and upon Company Order the Trustee shall authenticate and deliver, to such beneficial owner Certificated Security(ies) in an equivalent amount to such beneficial
interest in such Global Security; and 

  
 15 









 3) the Registrar shall decrease such Global Security by such amount in accordance with the
foregoing. 
 (iii) Transfer and Exchange of Certificated Securities. When Certificated Securities are
presented to the Registrar with a request: (x) to register the transfer of such Certificated Securities; or (y) to exchange such Certificated Securities for an equal principal amount of Certificated Securities of other authorized
denominations, the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Securities surrendered for transfer or
exchange shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. 

(iv) Restrictions on Transfer of a Certificated Security for a Beneficial Interest in a Global Security. A
Certificated Security may not be exchanged for a beneficial interest in a Global Security except upon satisfaction of the requirements set forth below. 
 Upon receipt by the Trustee of a Certificated Security, 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 Security to reflect an increase in the aggregate principal amount of the Securities represented by the Global
Security, such instructions to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Security 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 Securities represented by the Global Security to be increased by the aggregate principal amount of the Certificated Security 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 Security equal to the principal amount of the Certificated Security so cancelled. If no Global
Securities are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Global Security in the appropriate principal amount. 

(b) The provisions of clauses (i), (ii), (iii) and (iv) below shall apply only to Global Securities: 

(i) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in
whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Security may be exchanged for Securities registered in the name of any Person designated by
the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such Depositary has ceased to be a “clearing agency” registered under
the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days or (B) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to clause
(A) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (B) above may be 

  
 16 









 
exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security;
provided that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security. 

(ii) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully
registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the
Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be
exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by
an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such
exchange to or upon the order of the Depositary or an authorized representative thereof. 
 (iii) Subject to the
provisions of Subsection (c) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members (as defined below) and Persons that may hold interests through Agent Members, to take any action which a
Holder is entitled to take under this Indenture or the Securities. 
 (iv) In the event of the occurrence of any
of the events specified in clause (i) above, the Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 

(c) Neither any members of, or participants in, the Depositary (collectively, the “Agent Members”) nor
any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, and the
Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes whatsoever. Notwithstanding the
foregoing, 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 the Depositary or such nominee, as the case may
be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security. The
registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture
or the Securities. 

  
 17 









 Section 2.13 CUSIP and ISIN Numbers. The Company, in issuing the Securities, may
use CUSIP and ISIN numbers for such Securities (if then generally in use), and, if so, the Trustee shall use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders; provided, however, that neither the Company nor
the Trustee shall have any responsibility for any defect in the CUSIP or ISIN number that appears on any Security, check, advice of payment or redemption notice, and any such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption 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 or ISIN numbers. 
 Section 2.14 Further Issues. The Company may, without the consent of the Holders, issue Additional Securities in an unlimited aggregate principal amount under this Indenture with the same
terms as the Initial Securities; provided, that if the Additional Securities are not fungible with the Initial Securities for United States federal income tax purposes, the Additional Securities will have separate CUSIP and ISIN numbers. Any
such Additional Securities will, for all purposes of this Indenture, including waivers, amendments and offers to purchase, be treated as part of the same series as the Initial Securities. 

ARTICLE 3 

REPURCHASES 
 Section 3.01 Right of Repurchase. A repurchase of the Securities by the Company, as permitted by any provision of this Indenture, shall be made with respect to a repurchase at a Holder’s
option in connection with the occurrence of a Fundamental Change, in accordance with paragraph [•] of the Securities and Section 3.04 hereof in accordance with the applicable provisions of this Article 3. 

Section 3.02 No Sinking Fund. No sinking fund is provided for the Securities. 

Section 3.03 No Optional Redemption. The Company is not permitted to redeem the Securities prior to the Maturity Date.

 Section 3.04 Repurchase of Securities at Option of the Holder Upon a Fundamental Change . 

(a) If a Fundamental Change occurs, the Securities shall be repurchased by the Company, at the option of the Holder thereof, in cash, at
100% of the principal amount plus accrued and unpaid interest (including Additional Interest), if any, to (but excluding) such Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), as
of the date that is no fewer than 20 Business Days and no more than 45 Business Days after the date of the Fundamental Change Notice delivered by the Company (the “Fundamental Change Repurchase Date”), subject
to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.04(c). If the Fundamental Change Repurchase Date with respect to any Securities is after a Record Date and on or prior to the immediately following
Interest Payment 

  
 18 









 
Date, then (i) accrued and unpaid interest (including Additional Interest, if any) on such Securities to, but excluding, such Interest Payment Date shall be paid, on such Interest Payment
Date, to the Holder of record of such Securities at the Close of Business on such Record Date and (ii) the Fundamental Change Repurchase Price for such Securities shall not include such accrued and unpaid interest (or any Additional Interest)
and the Fundamental Change Repurchase Price for such Securities, instead, shall be equal to 100% of the principal amount of such Securities. 
 A “Fundamental Change” shall be deemed to have occurred at such time after the Securities are originally issued that any of the following events shall occur: 

(i) a “person” other than the Company, its wholly owned Subsidiaries or its or their employee benefit plans, files a Schedule TO
or any schedule, form or report under the Exchange Act disclosing that such person has become the direct or indirect Beneficial Owner of the Company’s common equity representing more than 50% of the voting power of the Company’s common
equity; 
 (ii) the Company merges or consolidates with or into any other person (other than a Subsidiary), any merger of another
person into the Company, or the Company conveys, sells, transfers or leases all or substantially all of its assets to another person (other than a Subsidiary), other than any transaction: (A) involving a merger or consolidation that does not
result in any reclassification, conversion, exchange or cancellation of the Company’s outstanding Common Stock, or (B) pursuant to which the holders of the Company’s shares of Common Stock immediately prior to the transaction have the
entitlement to exercise, directly or indirectly, 50% or more of the total voting power of all shares of Capital Stock entitled to vote generally in the election of directors of the continuing or surviving corporation or direct or indirect parent
thereof immediately after the transaction, with such Holders’ proportional voting power immediately after the transaction vis-à-vis each other with respect to the securities they receive in such transaction being in substantially the
same proportions as their respective voting power vis-à-vis each other with respect to the Common Stock that they held immediately before such transaction, or (C) which is effected solely to change the Company’s jurisdiction of
incorporation and results in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of common stock of the surviving entity; 
 (iii) the Company’s stockholders approve any plan or proposal for the Company’s liquidation or dissolution; or 
 (iv) a Termination of Trading. 
 Notwithstanding the foregoing provisions of this
Section 3.04, for purposes of this Indenture a Fundamental Change shall not be deemed to have occurred if at least 90% of the consideration (excluding cash payments for fractional shares and cash payments made pursuant to dissenters’
appraisal rights) in a merger or consolidation otherwise constituting a Fundamental Change under clause (i) and/or clause (ii) above consists of shares of common stock or depositary receipts in respect of the Company’s common stock or
common equity interests traded, in each case, on the NASDAQ, the NASDAQ Global Select Market or the NYSE (or any of their respective successors), or will be so traded immediately following the merger or


  
 19 









 
consolidation, and as a result of the merger or consolidation the Securities become convertible into such consideration. 
 For purposes of this Section 3.04, (x) whether a Person is a “Beneficial Owner” shall be determined in accordance with Rule 13d–3 under the Exchange Act and
(y) “person” includes any syndicate or group that would be deemed to be a “person” under Section 13(d)(3) of the Exchange Act. 
 At least three Business Days before the Fundamental Change Notice Date (as defined below), the Company shall deliver an Officers’ Certificate to the Trustee specifying: 

(i) the information required by Section 3.04(b); and 
 (ii) whether the Company desires the Trustee to give the Fundamental Change Notice required by Section 3.04(b). 
 (b) No later than 10 calendar days after the Company knows or reasonably should know of the occurrence of a Fundamental Change, the Company shall mail a written notice of the Fundamental Change (the
“Fundamental Change Notice,” the date of such mailing, the “Fundamental Change Notice Date”) by first-class mail to the Trustee and to each Holder (and to Beneficial Owners as required by applicable law). The
notice shall include a form of Fundamental Change Repurchase Notice to be completed by the Holder and shall state: 
 (i)
briefly, the nature of the Fundamental Change and the date of such Fundamental Change; 
 (ii) the date by which the Fundamental
Change Repurchase Notice pursuant to Section 3.04(c) must be given; 
 (iii) the Fundamental Change Repurchase Date;

 (iv) the Fundamental Change Repurchase Price; 
 (v) the name and address of the Paying Agent and the Conversion Agent; 
 (vi) the
Conversion Rate applicable on such Conversion Date and any adjustments thereto; 
 (vii) that the Securities as to which a
Fundamental Change Repurchase Notice has been given may be converted if they are otherwise convertible pursuant to Article 10 hereof only if the Fundamental Change Repurchase Notice has been withdrawn in accordance with the terms of this Indenture;

 (viii) that the Securities must be surrendered to the Paying Agent to collect payment; 

(ix) that the Fundamental Change Repurchase Price for any Security as to which a Fundamental Change Repurchase Notice has been duly given
and not withdrawn will be paid 

  
 20 









 
promptly following the later of the Fundamental Change Repurchase Date and the time of surrender of such Security as described in (viii) above; 

(x) briefly, the procedures the Holder must follow to exercise rights under this Section 3.04; 

(xi) briefly, the conversion rights, if any, of the Securities; 
 (xii) the procedures for withdrawing a Fundamental Change Repurchase Notice; 

(xiii) that, unless the Company defaults in making payment of such Fundamental Change Repurchase Price on the Securities surrendered for
repurchase by the Company will cease to accrue on and after the Fundamental Change Repurchase Date; and 
 (xiv) the CUSIP and
ISIN number(s) of the Securities. 
 Simultaneously with the provision of the Fundamental Change Notice, the Company shall
publish on the Company’s website or through another public medium the Company may use at that time a notice containing the information in above clauses (i) through (xiv). 

(c) A Holder may exercise its rights specified in Section 3.04(a) upon delivery of a written notice of repurchase (a
“Fundamental Change Repurchase Notice”) and any Securities to which the right is being exercised to the Trustee (for Global Securities pursuant to the Applicable Procedures) at any time on or prior to the Close of Business on the
Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date, stating: 
 (i) the portion of the principal
amount of the Securities which the Holder will deliver to be purchased, which portion must be $1,000 or an integral multiple thereof; 
 (ii) that such Securities shall be repurchased pursuant to the terms and conditions specified in Paragraph 6 of the Securities; and 
 (iii) if Certificated Securities have been issued, the certificate numbers of the Securities which the Holder will deliver to be repurchased. 

The delivery of such Security to the Trustee with the Fundamental Change Repurchase Notice (together with all necessary endorsements) at
the offices of the Trustee shall be a condition to the receipt by the Holder of the Fundamental Change Repurchase Price therefor; provided, however, that such Fundamental Change Repurchase Price shall be so paid pursuant to this
Section 3.04 only if the Security so delivered to the Trustee, if any, shall conform in all material respects to the description thereof set forth in the related Fundamental Change Repurchase Notice. 

The Company shall repurchase from the Holder thereof, pursuant to this Section 3.04, a portion of a Security if the principal amount
of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Security also apply to the repurchase of such portion of such Security. 

  
 21 









 Any repurchase by the Company contemplated pursuant to the provisions of this
Section 3.04 shall be consummated by the delivery of the consideration to be received by the Holder on the Fundamental Change Repurchase Date. 
 (d) Procedure upon Repurchase. The Company shall deposit cash, at the time and in the manner as provided in Section 3.06, sufficient to pay the aggregate Fundamental Change Repurchase Price of
all Securities to be repurchased pursuant to this Section 3.04. 
 Section 3.05 Effect of Fundamental Change
Repurchase Notice. Upon receipt by the Paying Agent of the Fundamental Change Repurchase Notice specified in Section 3.04(c), the Holder of the Security in respect of which such Fundamental Change Repurchase Notice was given shall (unless
such Fundamental Change Repurchase Notice is withdrawn as specified in the following paragraph) thereafter be entitled to receive solely the Fundamental Change Repurchase Price with respect to such Security. Such Fundamental Change Repurchase Price
shall be paid to such Holder, subject to receipt of funds by the Paying Agent, promptly following the later of (i) the Fundamental Change Repurchase Date with respect to such Security (provided the conditions in Section 3.04(c) have
been satisfied) and (ii) the time of delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.04(c). Securities in respect of which a Fundamental Change Repurchase Notice has been given by the
Holder thereof may not be converted pursuant to Article 10 hereof on or after the date of the delivery of such Fundamental Change Repurchase Notice unless such Fundamental Change Repurchase Notice has first been validly withdrawn as specified in the
following two paragraphs. 
 A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal
delivered to the office of the Paying Agent in accordance with the Fundamental Change Repurchase Notice at any time prior to the Close of Business on the last day prior to the Fundamental Change Repurchase Date, specifying: 

(a) the principal amount of the Security with respect to which such notice of withdrawal is being submitted, in multiples of $1,000;

 (b) if Certificated Securities have been issued, the certificate number of the Security in respect of which such notice of
withdrawal is being submitted; and

 Section 3.06 Deposit of Fundamental Change Repurchase Price. Prior to 10:00 a.m.
(New York City time) on the Fundamental Change Repurchase Date, as the case may be, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an affiliate of either of them is acting as the
Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of cash (in immediately available funds if deposited on such Business Day), sufficient to pay the aggregate Fundamental Change Repurchase Price of all the
Securities or portions thereof which are to be repurchased as of the Fundamental Change Repurchase Date. 

  
 22 









 Section 3.07 Securities Repurchased in Part. Any Certificated Security that is
to be repurchased 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 duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or
Securities, 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 Security so surrendered which is not repurchased, or in the case of a
Global Security, the Company shall instruct the Registrar to decrease such Global Security by the principal amount of the repurchased portion of the Security surrendered. 
 Section 3.08 Repurchases Following Acceleration of the Securities. Notwithstanding anything in this Indenture or the Securities to the contrary, there shall be no repurchase of any Securities
pursuant to Section 3.04 hereof if the principal amount of the Securities has been accelerated pursuant to the applicable provisions of this Indenture and such acceleration shall not have been rescinded on or before the Fundamental Change
Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Securities). The Paying Agent will promptly return to the respective
Holders thereof any Securities tendered to it for repurchase pursuant to Section 3.04 hereof during the continuance of such an acceleration (except in the case of an acceleration resulting from a Default by the Company in the payment of the
Fundamental Change Repurchase Price with respect to such Securities) and shall cancel any instructions for a book-entry transfer of the Securities in compliance with the procedures of the Depositary, in which case, upon such return or cancellation,
the Fundamental Change Repurchase Notice, as the case may be, with respect thereto shall be deemed to have been withdrawn. 

Section 3.09 Covenant to Comply with Securities Laws Upon Repurchase of Securities. When complying with the provisions of
Article 3 hereof (provided that such repurchase constitutes an “issuer tender offer” for purposes of Rule 13e–4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of
such offer or repurchase), the Company shall, to the extent applicable, (a) comply with Rule 13e–4 and Rule 14e–1 (or any successor provision) under the Exchange Act, (b) file the related Schedule TO (or any successor schedule,
form or report) under the Exchange Act, and (c) otherwise comply with any applicable federal and state securities laws so as to permit the rights and obligations under Section 3.04 to be exercised in the time and in the manner specified in
Section 3.06. 
 Section 3.10 Repayment to the Company. The Trustee and the Paying Agent shall return to the
Company any cash that remains unclaimed as provided in Paragraph 10 of the Securities, held by them for the payment of the Fundamental Change Repurchase Price; provided, however, that to the extent that the aggregate amount of cash
deposited by the Company pursuant to Section 3.06 exceeds the aggregate Fundamental Change Repurchase Price of the Securities or portions thereof which the Company is obligated to repurchase as of the Fundamental Change Repurchase Date, then,
unless otherwise agreed in writing with the Company, promptly after the Business Day following the Fundamental Change Repurchase Date, the Trustee shall return any such excess to the Company.

following the applicable Fundamental Change Repurchase Date) the Trustee or the Paying Agent holds, in accordance with this Indenture, cash sufficient to pay all such amounts then due. 

Section 4.02 SEC and Other Reports. 
 (a) The Company shall, so long as any of the Securities are outstanding, electronically file with the Commission the annual, quarterly and other periodic reports that the Company is required to file (or

provisions of TIA Section 314(a). Delivery of any reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate). Delivery of such
reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained

 (b) In the event that the Company is required to pay any Additional Interest pursuant to Section 6.01, the Company shall provide a direction or order in the form of a written notice to the Trustee
(and if the Trustee is not the Paying Agent, to the Paying Agent) of the Company’s obligation to pay such Additional Interest no later than three Business Days prior to date on which any such Additional Interest is scheduled to be paid. Such
notice shall set forth the amount of such 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. The Trustee shall not at any time be under 

  
 24 









 
any duty or responsibility to any Holder to determine whether any Additional Interest is payable, or with respect to the nature, extent, or calculation of the amount of any Additional Interest
owed, or with respect to the method employed in such calculation of any Additional Interest. 
 Section 4.03 Compliance
Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year (beginning with the fiscal year ending December 31, 2013) of the Company an Officers’ Certificate, stating whether or not to the

and if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

agency (other than a change in the location of the Corporate Trust Office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 12.02. 
 The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind

 (a) either (i) the Company shall be the

 (b) immediately after giving effect to such
transaction, no Event of Default, and no event that, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and

 (e) the Company defaults in its
obligation to deliver the shares of Common Stock required to be delivered upon conversion of the Securities, together with cash in lieu thereof in respect of any fractional shares, upon conversion of any Securities; 

  
 26 









 (f) the Company or any of its Significant Subsidiaries defaults under any mortgage,
indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed (other than (i) any non-recourse indebtedness for money borrowed or (ii) indebtedness for money
borrowed of a Subsidiary of the Company if such Subsidiary is a special purpose entity that serves as a vehicle to obtain financing that is otherwise non-recourse to the Company and its other Subsidiaries) (“Indebtedness”) by the
Company or any of its Significant Subsidiaries, whether such Indebtedness exists before the Company’s entrance into this Indenture or is created after such date, if the default: 

(i) is caused by a failure to pay at Stated Maturity the principal of such Indebtedness prior to the expiration of the
grace period provided in such Indebtedness on the date of such default (a “Payment Default”), or 
 (ii) results in the acceleration of such Indebtedness prior to its express maturity, 
 and, in
each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $50.0 million or
more unless such Payment Default is cured or waived or such acceleration is rescinded, stayed or annulled within 30 days after written notice from the Trustee or the Holders of at least 25% in principal amount of the Notes (provided, however that if
any such failure or acceleration referred to in (i) or (ii) above shall cease to be cured, waived, rescinded or annulled, then the Event of Default by reason thereof shall be deemed not to have occurred); 

(g) the Company defaults in its performance of any covenant or agreement in respect of the Securities or this Indenture for 60 days after
receipt by the Company of a Notice of Default from the Trustee or after receipt by the Company and the Trustee of a Notice of Default from the Holders of at least 25% in aggregate principal amount of the Securities then outstanding; 

(h) [Reserved]; 

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

(i) commences a voluntary case; 
 (ii) consents to the entry of an order for relief against it in an involuntary case; 
 (iii) consents to the appointment of a Custodian of it or for any substantial part of its property; or 
 (iv) makes a general assignment for the benefit of its creditors; or 
 (v) takes any comparable action under any foreign laws relating to insolvency; or

(ii) appoints a Custodian of the Company or for any substantial part of its property; 

(iii) orders the winding up or liquidation of the Company; or 

(iv) grants any similar relief under any foreign laws; 
 and in each such case the order or decree remains unstayed and in effect for 60 days. 
 The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any administrative or governmental body. 
 The term
“Bankruptcy Law” means Title 11, United States Code, or any similar federal, state or non-U.S. law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law. 
 A Default under clause (g) is not an Event of Default until the Trustee or
the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company (and in the case of such notice by Holders, the Trustee) of the Default and the Company does not cure such Default within the time
specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default”. 
 The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any Default and any event of which it becomes aware
that with the giving of notice or the lapse of time would become an Event of Default, its status and what action the Company is taking or proposes to take with respect thereto. 

Notwithstanding anything in this Indenture or in the Securities to the contrary (including Section 4.02), at the election of the
Company, the sole remedy for an Event of Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that it is required to file with
the SEC pursuant to Section 13 or 15(d) of the Exchange Act or (ii) the Company’s failure to comply with its reporting obligations as set forth in Section 4.02 (the obligations described in clauses (i) and (ii) above,
the “Company’s Filing Obligations”) shall for the first 270 calendar days after the occurrence of such an Event of Default consist exclusively of the right to receive additional interest (“Additional Interest”)
on the Securities at an annual rate equal to (x) 0.25% per annum of the principal amount of the Securities outstanding for the first 180 days beginning on, and including, the date on which such an Event of Default first occurs and
(y) 0.50% per annum of the principal amount of the Securities outstanding for the last 90 days of such 270-day period as long as such Event of Default is continuing. If the Company so elects to pay Additional Interest,


  
 28 









 
any such Additional Interest shall be payable in the same manner and on the same dates as the interest payable on the Securities. On the 271st calendar day after such Event of Default (if the
Event of Default relating to the Company’s failure to comply with the Company’s Filing Obligations is not cured or waived prior to such 271st calendar day), the Securities shall be subject to acceleration under Section 6.02. This
provision shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. In the event the Company does not elect to pay the Additional Interest following an Event of Default relating to the Company’s Filing
Obligations in accordance with this provision or the Company elected to make such payment but does not pay the Additional Interest when due, the Securities shall be immediately subject to acceleration under Section 6.02. In order to elect to
pay the Additional Interest as the sole remedy during the first 270 days after the occurrence of an Event of Default relating to the failure by the Company to comply with the Company’s Filing Obligations in accordance with this provision, the
Company must notify all Holders of the Securities, the Trustee and the Paying Agent of such election on or prior to the Close of Business on the date on which such Event of Default first occurs. Upon the Company’s failure to timely give such
notice, the Securities shall be immediately subject to acceleration under Section 6.02. In addition, the Company shall deliver to the Trustee a certificate stating (i) that the Additional Interest is payable under this Section 6.01,
and (ii) the date on which such Additional Interest is payable. Unless and until a Trust Officer receives at the Corporate Trust Office such a notice, the Trustee may assume without inquiry that no Additional Interest is payable. If the
Additional Interest has been paid by the Company directly to the Persons entitled to them, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. 

Section 6.02 Acceleration. If an Event of Default (other than an Event of Default specified in Sections 6.01(i) or 6.01(j))
occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding by notice to the Company and the Trustee, may declare the principal amount of Securities
outstanding plus accrued and unpaid interest (including Additional Interest), if any, on all the Securities to be immediately due and payable. Upon such a declaration, such accelerated amount shall be due and payable immediately. If an Event of
Default specified in Sections 6.01(i) or 6.01(j) occurs and is continuing, the principal amount of Securities outstanding plus accrued and unpaid interest on all the Securities shall, automatically and without any action by the Trustee or any
Holder, become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding by notice to the
Trustee and the Company and without notice to any other Holder may rescind any declaration of acceleration if the rescission is before any judgment or decree has been obtained and if all existing Events of Default have been cured except nonpayment
of the principal amount or accrued but unpaid interest (including Additional Interest), if any, that have become due solely as a result of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

 Section 6.03 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 (including Additional Interest), if any, and any payment of the Fundamental Change Repurchase Price or premium on the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

 The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of the Securities 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 6.04 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Securities at the time
outstanding by notice to the Trustee and without notice to any other Holder may waive an existing default and its consequences except (a) an Event of Default described in Section 6.01(a), (b) a default in respect of a provision that
under Section 9.02 cannot be amended without the consent of each Holder or (c) a default which constitutes a failure to convert any Security in accordance with the terms of Article 10. When a Default is waived, it is deemed cured, but no
such waiver shall extend to any subsequent or other default or impair any consequent right. 
 Section 6.05 Control by
Majority. The Holders of a majority in aggregate principal amount of the Securities 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. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is prejudicial to the rights of other Holders or would
potentially involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the
Trustee shall be entitled to reasonable indemnification against all losses and expenses caused by taking or not taking such action. 
 Section 6.06 Limitation on Suits. A Holder may pursue any remedy with respect to this Indenture or the Securities only if: 

(a) such Holder shall have previously given to the Trustee written notice of a continuing Event of Default; 

(b) the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding make a written request;

 (c) such Holder shall have offered indemnity reasonably satisfactory to the Trustee to pursue such proceeding as trustee; and

 (d) the Trustee has failed to institute such proceeding within 60 days after such notice and offer of indemnity and, during
such 60-day period, has not received from the Holders of at least a majority in aggregate principal amount of the Securities outstanding at the time a direction inconsistent with such 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 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture,
the right of any Holder to bring suit for the enforcement of payment 

  
 30 









 
of principal, accrued and unpaid interest (including Additional Interest), if any, and any payment of the Fundamental Change Repurchase Price or premium on or after the due dates expressed in
such Holder’s Securities, and to convert the Securities in accordance with Article 10, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) 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 (including Additional Interest) to the extent lawful) and the amounts provided for in Section 7.07. 

Section 6.09 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, in the event
that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any
other amounts due the Trustee under Section 7.07. 
 Section 6.10 Priorities. If the Trustee collects any money
pursuant to this Article 6, it shall pay out the money in the following order: 
 FIRST: to the Trustee for amounts due under
Section 7.07; 
 SECOND: to Holders for amounts due and unpaid on the Securities for principal, accrued and unpaid interest
(including Additional Interest), if any, and any payment of the Fundamental Change Repurchase Price or premium ratably, without preference or priority of any kind, according to such amounts due and payable on the Securities; 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 6.10. At least 15 days before such record date, the Company shall mail to each Holder and the
Trustee a notice that states the record date, the payment date and the amount to be paid. 
 Section 6.11 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of
the Securities at the time outstanding. 

  
 31 









 Section 6.12 Waiver of Stay, Extension or Usury 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 7 

TRUSTEE 

Section 7.01 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a
prudent Person would exercise or use under the circumstances 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 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. 
 (c) The Trustee may not be relieved from
liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
 (i) this paragraph does not limit the effect of Section 7.01(b); 
 (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 6.05. 
 (d) Every provision of this Indenture that in any way relates
to the Trustee is subject to Sections 7.01(a), (b) and (c). 
 (e) The Trustee shall not be liable for interest on any
money received by it. 

  
 32 









 (f) Money or Common Stock held in trust by the Trustee need not be segregated from other
funds except to the extent required by law. 
 (g) 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. 
 (h) 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 7 and to the
provisions of the TIA, and the provisions of this Article 7 shall apply to the Trustee, Registrar, Paying Agent and Conversion Agent. 
 (i) The Trustee shall not be deemed to have notice of a Default or an Event of Default unless (i) a Trust Officer of the Trustee has received written notice thereof from the Company or any Holder or
(ii) a Trust Officer shall have actual knowledge thereof. 
 Section 7.02 Rights of Trustee. 

(a) The Trustee may conclusively rely on any 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 the 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 expense of the Company and shall incur no liability of any kind by
reason of such inquiry or investigation. 
 (b) Before the Trustee acts or refrains from acting (except in connection with an
application for authorization of Securities pursuant to Section 2.02), it may require an Officers’ 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 Officers’ 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. 
 (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 its rights or powers; 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 advice or opinion of counsel
with respect to legal matters relating to this Indenture and the Securities 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. 

  
 33 









 (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 pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and
liabilities that might be incurred by it in compliance with such request or direction. 
 (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 and Conversion Agent. 
 (i) The
Trustee may request that the Company deliver an Officers’ 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 Officers’
Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities 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, Conversion Agent or co-registrar may do the same with like rights. However, the
Trustee must comply with Sections 7.10 and 7.11. 
 Section 7.04 Trustee’s Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity, priority or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, 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 Securities or in the Securities other than the Trustee’s certificate of authentication. 

Section 7.05 Notice of Defaults. If a Default or Event of Default occurs and is continuing, the Trustee shall mail to each
Holder notice of the Default or Event of Default within 90 days after it is known to a Trust Officer or written notice of it is received by the Trustee. Except in the case of a Default described in Section 6.01(a), the Trustee may withhold the
notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders. The second sentence of this Section 7.05 shall be in lieu of the proviso to TIA Section 315(b)
and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have knowledge of a Default unless a Trust Officer of the Trustee has received written notice of such Default. 

Section 7.06 Reports by Trustee to Holders. As promptly as practicable after each December 31 beginning with
December 31, 2013, and in any event prior to March 31 in each year thereafter, the Trustee shall mail to each Holder a brief report dated as of December 31 each year that complies with TIA Section 313(a), if and to the extent
required by such subsection. The Trustee shall also comply with TIA Section 313(b). 

  
 34 









 A copy of each report at the time of its mailing to Holders shall be filed with the SEC and
each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof. 

Section 7.07 Compensation and Indemnity. 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 its services. 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. The Company shall fully indemnify the Trustee 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, including the costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other
Person). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company of any claim for which it may seek indemnity of which a Trust Officer has actually received written
notice shall not relieve the Company of its obligations hereunder except to the extent such failure shall have materially prejudiced the Company. The Company shall defend the claim and the Trustee shall cooperate in the defense. If the Trustee is
advised by counsel in writing that it may have available to it defenses which are in conflict with the defenses available to the Company, then the Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such
counsel. 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. The Company need not pay for any settlement made by the
Trustee without the Company’s consent, such consent not to be unreasonably withheld. All indemnifications and releases from liability granted hereunder to the Trustee shall extend to its officers, directors, employees, agents, attorneys,
custodians, successors and assigns. 
 To secure the Company’s payment obligations in this Section 7.07, the Trustee
shall have a lien prior to the Securities 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 (including Additional Interest), if any, and any payment
of the Fundamental Change Repurchase Price or premium on particular Securities. 
 The Company’s payment obligations
pursuant to this Section shall survive the resignation or removal of the Trustee and the discharge of this Indenture. In the event that the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(i) or 6.01(j) with
respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law. 

Section 7.08 Replacement of Trustee. The Trustee may resign at any time by so notifying the Company at least 30 days
prior to the proposed resignation. The Holders of a majority in aggregate principal amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee. The Company shall remove the Trustee if: 

  
 35 









 (a) the Trustee fails to comply with Section 7.10; 

(b) the Trustee is adjudged bankrupt or insolvent; 
 (c) a receiver or other public officer takes charge of the Trustee or its property; or 
 (d) the Trustee otherwise becomes incapable of acting. 
 If the Trustee resigns,
is removed by the Company or by the Holders of a majority in aggregate principal amount of the Securities then outstanding, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the
retiring Trustee), the Company shall promptly appoint a successor Trustee. 
 A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall upon payment of all of its costs and the costs of its agents and counsel promptly transfer all property held by it as Trustee to
the successor Trustee, subject to the lien provided for in Section 7.07. 
 If a successor Trustee does not take office
within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in aggregate principal amount of the Securities then outstanding may petition at the expense of the Company any court of competent
jurisdiction for the appointment of a successor Trustee. 
 If the Trustee fails to comply with Section 7.10, any Holder
who has been a bona fide Holder of a Security for at least six months may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall
continue for the benefit of the retiring Trustee. 
 Section 7.09 Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association
without any further act shall be the successor Trustee. 
 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 Securities 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 Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any such successor to the Trustee may authenticate such Securities either in the name of any
predecessor hereunder or in the name of the successor to the Trustee. 
 Section 7.10 Eligibility;
Disqualification. The Trustee shall at all times satisfy the requirements of TIA Section 310(a). The Trustee shall have (or, in the case of a corporation 

  
 36 









 
included in a bank holding company system, the related bank holding company shall have) a combined capital and surplus of at least $50,000,000 as set forth in its (or its related bank holding
company’s) most recent published annual report of condition. The Trustee shall comply with TIA Section 310(b), subject to the penultimate paragraph thereof; provided, however, that there shall be excluded from the operation
of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA
Section 310(b)(1) are met. 
 Section 7.11 Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein.

 Section 7.12 Trustee’s Application for Instructions from the Company. Any application by the Trustee
for written instructions from the Company may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such
omission shall be effective. The Trustee shall not be liable to the Company for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which
date shall not be less than three Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the
effective date in the case of any omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted. 
 ARTICLE 8 
 DISCHARGE OF INDENTURE 

Section 8.01 Discharge of Liability on Securities. When (a) the Company delivers to the Registrar all outstanding
Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (b) all outstanding Securities have become due and payable, and the Company irrevocably deposits with the Trustee or delivers to the Holders, as
applicable, cash and shares of Common Stock (solely to satisfy outstanding conversions, if applicable) sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07), and if
in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 7.07, cease to be of further effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture with
respect to the Securities on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company. 
 Section 8.02 Repayment to the Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time.


  
 37 









 Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay
to the Company upon request any money held by them for payments on the Securities that remains unclaimed for two years after the date on which such payments became due, and, thereafter, Holders entitled to the money must look to the Company for
payment as general creditors and all liability of the Trustee or Paying Agent with respect to such money will cease. 

ARTICLE 9 

AMENDMENTS 
 Section 9.01 Without Consent of Holders. The Company, the Trustee and the Paying Agent may amend or supplement this Indenture or the Securities without the consent of any Holder so long
as such changes, other than those in clause (b), do not materially and adversely affect the interests of the Holders: 
 (a) to
cure any ambiguity, omission, defect or inconsistency; 
 (b) to comply with Article 5; 

(c) to make provisions with respect to the conversion rights of the Holders in accordance with Section 10.15. 

(d) to provide for uncertificated Securities in addition to or in place of Certificated Securities; 

(e) to provide any security for or guarantee of the Securities; 
 (f) to comply with any requirement to effect or maintain the qualification of this Indenture under the TIA; 
 (g) to add to the Company’s covenants for the benefit of the Holders or to surrender any right or power conferred upon the Company by this Indenture; 

(h) to add Events of Default with respect to the Securities; 
 (i) to add circumstances under which the Company will pay additional interest on the Securities; 
 (j) to make any change that does not adversely affect any outstanding Securities in any material respect; and 
 (k) to conform the Securities and this Indenture with the descriptions set forth in the “Description of Notes” section of the preliminary prospectus, dated [•], 2013, as supplemented by the
related pricing term sheet. 
 After an amendment under this Section 9.01 becomes effective, the Company shall mail to
Holders a notice briefly describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section. 

  
 38 









 Section 9.02 With Consent of Holders. With the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities at the time outstanding, the Company, the Trustee and the Paying Agent may amend or supplement this Indenture or the Securities. However, without the consent of each
Holder affected, an amendment to this Indenture or the Securities may not: 
 (a) reduce the amount of Securities whose Holders
must consent to an amendment, supplement or waiver; 
 (b) reduce any interest rate referred to in Paragraph 1 of the Securities
or change the time for payment of interest (including Additional Interest) thereon; 
 (c) reduce the principal amount of or
change the Maturity Date of any Security; 
 (d) reduce the Fundamental Change Repurchase Price of any Security or change the
time at which the Securities may be repurchased; 
 (e) make any payments on the Securities payable in currency other than as
stated in the Security; 
 (f) impair a Holder’s right to institute suit for the enforcement of any payment on the
Securities; 
 (g) make any change in the percentage of principal amount of Securities necessary to waive compliance with the
provisions of Section 6.04 or this Section 9.02; 
 (h) waive a continuing default or Event of Default regarding any
payment on the Securities; or 
 (i) except as required by this Indenture as of October [•], 2013 (without giving effect to
any amendments, side agreements or supplemental indentures thereto), make any change that adversely affects a Holder’s rights under Sections 3.04 to 3.06 hereof, under Article 10 hereof or under Paragraph 6 or 7 of the Securities. 

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment under this
Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment
under this Section. 
 Section 9.03 Compliance with Trust Indenture Act. Every supplemental indenture
executed pursuant to this Article shall comply with the TIA. 

  
 39 









 Section 9.04 Revocation and Effect of Consents, Waivers and Actions. A
consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of
the consent or waiver is not made on the Security. 
 However, any such Holder or subsequent Holder may revoke the consent or
waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the supplemental indenture setting forth the amendment or waiver becomes effective. After an amendment or
waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective in accordance with the terms of the supplemental indenture, which shall become effective upon the execution thereof by the Trustee. 

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their
consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date
(or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No
such consent shall be valid or effective for more than 120 days after such record date. 
 Section 9.05 Notation on or
Exchange of Securities. Securities authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture. If the Company shall so determine, new Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding Securities. 

Section 9.06 Trustee to Sign Supplemental Indentures. Upon the request of the Company, the Trustee shall sign any
supplemental indenture authorized pursuant to this Article 9 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental
indenture. In signing such supplemental indenture the Trustee shall be provided with, and (subject to the provisions of Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that
such amendment is authorized or permitted by this Indenture. 
 Section 9.07 Effect of Supplemental Indentures.
Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

 ARTICLE 10 
 CONVERSIONS 
 Section 10.01 Conversion Privilege and
Consideration. 
 (a) A Holder may convert such Security at any time until the Close of Business on the second Scheduled
Trading Day immediately preceding the Maturity Date. The “Conversion Rate” shall be that identified as such in Paragraph 7 of the Securities, subject to adjustment as herein set forth. A Holder may, during any applicable time
referred to herein, convert a portion of the principal amount of a Security if the portion converted is in a $1,000 principal amount or an integral multiple of $1,000. Provisions of this Indenture that apply to conversion of all of a Security also
apply to conversion of a portion of a Security. 
 Except as specifically described in this Article 10, the Conversion Rate will
not be subject to adjustment in the case of the issuance of any shares of Common Stock, or any securities convertible into or exchangeable for shares of Common Stock, or the right, option or warrant to purchase shares of Common Stock, or such
convertible or exchangeable securities. 
 (b) Subject to Section 10.01(a), upon conversion, a Holder will receive, for
each $1,000 principal amount of Securities surrendered, a number of shares of Common Stock equal to (i) $1,000 multiplied by (ii) the applicable Conversion Rate on such Conversion Date. 

(c) The Company shall deliver such shares of Common Stock to the Holder on the third Trading Day following the Conversion Date;
provided, however, that for any conversion that occurs on or after the Record Date for the payment of interest on the Securities on the Maturity Date and until the Close of Business on the second Scheduled Trading Day immediately
preceding the Maturity Date, the Company will deliver such shares on the Maturity Date. 
 Section 10.02 Conversion
Procedure. To convert a Security, a Holder must satisfy the requirements set forth in Paragraph 7 of the Securities. The first Business Day on which the Holder satisfies all those requirements and delivers an irrevocable conversion notice
together with such Holder’s Securities for conversion is the conversion date (the “Conversion Date”). 

The Person in whose name the certificate is registered shall be treated as a shareholder of record as of the Close of Business on the
Conversion Date. Upon conversion of a Security in its entirety, such Person shall no longer be a Holder of such Security. 
 No
payment or adjustment will be made for dividends on, or other distributions with respect to, any shares of Common Stock except as provided in this Article 10. 
 Upon conversion of a Security, that portion of accrued and unpaid interest (including Additional Interest), if any, through the Conversion Date with respect to the converted Security shall not be
cancelled, extinguished or forfeited, but rather, subject to Section 11.01(b), shall be deemed to be paid in full to the Holder thereof through delivery shares of Common Stock (together with the cash payment, if any, in lieu of fractional
shares) for the Security being

converted pursuant to the provisions hereof. The Company will not adjust the Conversion Rate to account for accrued interest, if any. 

If the last day on which a Security may be converted is a Legal Holiday, the Security may be surrendered on the next succeeding day that
is not a Legal Holiday. 
 If the Holder converts more than one Security at the same time, the number of shares of Common Stock
issuable upon the conversion and the amount of any cash paid in lieu of fractional shares shall be based on the total principal amount of the Securities converted. Upon surrender of a Security that is converted in part, the Company shall execute,
and the Trustee shall authenticate and deliver to the Holder, a new Security in an authorized denomination equal in principal amount to the unconverted portion of the Security surrendered, or in the case of a Global Security, the Company shall
instruct the Registrar to decrease such Global Security by the principal amount of the converted portion of the Security surrendered. 
 Section 10.03 Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of a Security. Instead, the Company will pay cash in lieu of fractional shares by
multiplying the Closing Sale Price of a full share of Common Stock on the Conversion Date (or if the Conversion Date is not a Trading Day, the next following Trading Day) by the fractional amount and rounding the product to the nearest whole cent.
Whether fractional shares are issuable upon a conversion will be determined on the basis of the total number of Securities that the Holder is then converting into Common Stock and the aggregate number of fractional shares, if any, of Common Stock
issuable upon such conversion. 
 All calculations under this Article 10 shall be made to the nearest cent or to the nearest
1/10,000th of a share, as the case may be. 
 Section 10.04 Taxes on Conversion. If a Holder submits a Security for
conversion, the Company shall pay all stamp and all other duties, if any, which may be imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares, if any, of Common
Stock upon the conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificates
representing the shares, if any, of Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than
the Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations. 
 Section 10.05
Company to Provide Stock. The Company shall, prior to issuance of any Securities under this Article 10, and from time to time as may be necessary, reserve out of its authorized but unissued shares of Common Stock a sufficient number of shares
of Common Stock to permit the conversion of the Securities. 
 Any shares of Common Stock delivered upon conversion of the
Securities shall be newly issued shares or treasury shares, 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. The Company will endeavor
promptly to comply with all federal and state securities laws 

  
 42 









 
regulating the offer and delivery of Common Stock, if any, upon conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national securities
exchange or in the over-the-counter market or such other market on which the shares of Common Stock are then listed or quoted. 

Section 10.06 Adjustment for Change in Capital Stock. If, after the Issue Date of the Securities, the Company: 

(a) pays a dividend or makes a distribution payable exclusively in shares of Common Stock on all or substantially all shares of the
Company’s Common Stock; 
 (b) subdivides the outstanding shares of Common Stock into a greater number of shares; or

 (c) combines the outstanding shares of Common Stock into a smaller number of shares; 

then the Conversion Rate will be adjusted based on the following formula: 

 
 



 
 where, 
  

			
	 CR’ =
	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately after the Open of Business on the
effective date of such subdivision or combination, as the case may be;
		
	 CR =
	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the Open of Business on
the effective date of such subdivision or combination, as the case may be;
		
	 OS’ =
	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the
Open of Business on the effective date of such subdivision or combination, as the case may be; and
		
	 OS =
	  	the number of shares of Common Stock outstanding immediately after such dividend or distribution, or immediately after the effective date of such subdivision or combination, as
the case may be.

 Any adjustment made under this Section 10.06 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 subdivision or combination, as applicable. If any dividend or distribution of the type described in this Section 10.06 is declared but not so
paid or made, or the outstanding shares of Common Stock are not so subdivided or combined, as the case may be, the applicable Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors


  
 43 









 
determines not to pay such dividend or distribution, or to effect such subdivision or combination, to the Conversion Rate that would then be in effect if such dividend, distribution, share
subdivision or share combination had not been declared. 
 Section 10.07 Adjustment for Rights Issue. If, after the
Issue Date of the Securities, the Company distributes any rights, options or warrants to all holders of the Company’s Common Stock entitling them to purchase (for a period expiring within 45 days after the date of issuance) shares of Common
Stock at a price per share less (or securities convertible into Common Stock having a conversion price per share that is less than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and
including the Trading Day immediately preceding the Ex-Dividend Date for such distribution, the Conversion Rate shall be adjusted in accordance with the formula: 
  





 
 where: 
  

			
	 CR’ =
	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such distribution;
		
	 CR =
	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
		
	 O =
	  	the number of shares of Common Stock outstanding at the Close of Business on the Trading Day immediately preceding the Ex-Dividend Date for such distribution;
		
	 N =
	  	the number of additional shares of Common Stock issuable pursuant to such rights, options or warrants;
		
	 P =
	  	the per-share offering price payable to exercise such rights, options or warrants for the additional shares; and
		
	 M =
	  	the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date with respect to the distribution.

 Any increase made under this Section 10.07 will be made successively whenever any such rights,
options or warrants are distributed and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. To the extent that shares of the Common Stock are not delivered after the expiration of such rights,
options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the applicable Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not
occurred. 

  
 44 









 For purposes of this Section 10.07, in determining whether any rights, options or
warrants entitle the holders to subscribe for or purchase Common Stock at less than the average of the Closing Sale Prices of Common Stock for each Trading Day in the applicable 10 consecutive Trading Day period, there shall be taken into account
any consideration received by the Company for such rights, options or warrants and any amount payable on exercise thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 

Section 10.08 Adjustment for Other Distributions. If, after the Issue Date of the Securities, the Company distributes to all
or substantially all holders of its Common Stock any of its debt, securities, assets or any rights, warrants or options to purchase securities of the Company (including securities or cash, but excluding (a) dividends or distributions (including
subdivisions) referred to in Section 10.06 and distributions of rights, warrants or options referred to in Section 10.07, (b) dividends or other distributions paid exclusively in cash (to which this Section 10.08 shall apply) and
(c) any Spin-off to which the provisions set forth below in this Section 10.08 shall apply) (“Distributed Property”), the Conversion Rate shall be adjusted, subject to the provisions of the last paragraph of this
Section 10.08, in accordance with the formula: 
  

									
	CR’	 	=	 	CR	 	×	  	    M    
	 	 	 	  	M – F

 where: 
  

			
	 CR’ =
	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such distribution;
		
	 CR =
	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
		
	 M =
	  	the average of the Closing Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on, and including, the Ex-Dividend Date for such distribution;
and
		
	 F =
	  	the fair market value, as determined by the Board of Directors, of the portion of those assets, securities, rights, warrants or options to be distributed in respect of each share
of Common Stock immediately prior to the Open of Business on the Ex-Dividend Date for such distribution.

 Such adjustment shall become effective immediately after the Open of Business on the Ex-Dividend Date for
such distribution. Notwithstanding the foregoing, if “F” as set forth above is equal to or greater than “M” as set forth above, in lieu of the foregoing adjustment, adequate provisions shall be made so that each Holder shall have
the right to receive on conversion in respect of each $1,000 principal amount of the Securities held by such Holder, in addition to the number of shares of Common Stock equal to the Conversion Rate, the amount and kind of Distributed Property such
Holder would have received had such Holder owned a number of shares of Common Stock equal to the Conversion Rate immediately prior to the record date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall again
be 

  
 45 









 
adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors thereof determines “F” for purposes of
this Section 10.08 by reference to the actual or when issued trading market for any Securities, it must in doing so consider the prices in such market over the same period used in computing the Closing Sale Prices of the Common Stock over the
10 consecutive Trading Day period ending on, and including, the Ex-Dividend Date for such distribution. 
 With respect to an
adjustment pursuant to this Section 10.08 where there has been a payment of a dividend or other distribution on the Common Stock in shares of capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary or
other business unit, where such capital stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation of the Spin-off) on a U.S. national securities exchange or reasonably comparable non-U.S. equivalent, which
is referred to herein as a “Spin-off,” the Conversion Rate will be increased based on the following formula: 
  





 
  

			
	 CR’ =
	  	the Conversion Rate in effect immediately after the Open of Business on the effective date for the Spin-off;
		
	 CR =
	  	the Conversion Rate in effect immediately prior to the Open of Business on the effective date for the Spin-off;
		
	 F =
	  	the average of the Closing Sale Prices of the capital stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock over
the first 10 consecutive Trading Day period immediately following, and including, the effective date for the Spin-off (such period, the “Valuation Period”); and
		
	 MP =
	  	the average of the Closing Sale Prices of the Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph of this Section 10.08 will be
made immediately after the Open of Business on the day after the last day of the Valuation Period, but will be given effect as of the Open of Business on the effective date for the Spin-off. For purposes of determining the Conversion Rate in respect
of any conversion during the 10 Trading Days commencing on the effective date for any Spin-off, references within the portion of this Section 10.08 related to “Spin-offs” to 10 consecutive 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. 
 For purposes of this Section 10.08, in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than the average of the
Closing Sale Prices of the Common Stock for each Trading Day in the applicable 10 consecutive Trading Day period, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable
on exercise or 

  
 46 









 
conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
 If, prior to a Conversion Date, a record date for a Spin-off has been set but the relevant dividend or distribution has not yet resulted in an adjustment to the Conversion Rate and a converting Holder is
not entitled to participate in the dividend or distribution with respect to the shares of Common Stock such Holder receives upon conversion (whether because such Holder was not a holder of such shares of Common Stock on the effective date for such
dividend or distribution or otherwise), then as promptly as practicable following the Conversion Date, the Company will deliver to such Holder a number of additional shares of Common Stock that reflects the increase to the Conversion Rate that
resulted from the Spin-off. 
 For purposes of this Section 10.08, 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 shares of 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 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 10.08 (and no adjustment to the Conversion Rate under this Section 10.08 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 10.08. If any such right,
option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different
securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights
(in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options
or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate
under this Section 10.08 was made: 
 (i) 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


  
 47 









 
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 
 (ii) 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. 

Section 10.09 Adjustment for Cash Distributions. If, after the Issue Date of the Securities, the Company distributes to all
or substantially all holders of its Common Stock any cash, the Conversion Rate shall be adjusted in accordance with the formula: 
  





 
  

			
	 CR’ =
	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such distribution;
		
	 CR =
	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
		
	 SP =
	  	the average of the Closing Sale Prices of Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend
Date for such distribution; and
		
	 C =
	  	the amount in cash per share the Company distributes to holders of Common Stock;

 Any increase to the applicable Conversion Rate made under this Section 10.09 shall become effective
immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the applicable Conversion Rate shall be decreased, effective as of the date the Board of Directors
thereof determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

Notwithstanding the foregoing, if “C” as set forth above is equal to or greater than “SP” as set forth above, in lieu
of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive on the date on which the relevant cash dividend or distribution is distributed to Holders of Common Stock, for each $1,000 principal
amount of Securities, the amount of cash such Holder would have received had such Holder owned a number of shares equal to the Conversion Rate on the record date for such distribution. If such dividend or distribution is not so paid or made, the
Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

  
 48 









 Section 10.10 Adjustment for Company Tender Offer. If, after the Issue Date of
the Securities, the Company or any Subsidiary of the Company makes a payment to holders of the shares of Common Stock in respect of a tender or exchange offer, other than an odd-lot offer, by the Company or any of its Subsidiaries for shares of
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 Closing Sale Prices over the 10 consecutive Trading Day period commencing on, and including
the Trading Day following the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be increased based on the following formula: 

 
 



 
  

			
	 CR’ =
	  	the Conversion Rate in effect immediately after the Open of Business on the Trading Day following the Expiration Date;
		
	 CR =
	  	the Conversion Rate in effect immediately prior to the Open of Business on the Trading Day following the Expiration Date;
		
	 F =
	  	the fair market value, as determined by the Board of Directors, of the aggregate consideration payable in such tender or exchange offer (up to any maximum amount specified in the
terms of the tender or exchange offer) for all shares of Common Stock the Company or any Subsidiary of the Company purchases in such tender or exchange offer, such fair market value to be measured as of the expiration time of the tender or exchange
offer (the “Expiration Time”);
		
	 OS =
	  	the number of shares of Common Stock outstanding immediately prior to the Expiration Time (prior to giving effect to such tender offer or exchange offer);
		
	 OS’ =
	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to such tender offer or exchange offer); and
		
	 SP =
	  	the average of the Closing Sale Prices of Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day following the Expiration
Date.

 The adjustment to the Conversion Rate under the preceding paragraph of this
Section 10.10 will be made immediately after the Open of Business on the 11th Trading Day following the Expiration Date but will be given effect at the Open of Business on the Trading Day following the Expiration Date. For purposes of determining the Conversion Rate, in respect of
any conversion during the 10 Trading Days commencing on the Trading Day following the Expiration Date, references within this Section 10.10 to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed
from, and including, the Trading Day following the Expiration Time to, but excluding, the relevant Conversion Date. 

  
 49 









 In the event that the Company or one of its Subsidiaries is obligated to purchase shares of
Common Stock pursuant to any such tender offer or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Rate shall
again be adjusted to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made. 
 Section 10.11 When No Adjustment Required. No adjustment need be made as a result of: 
 (a) the issuance of the rights pursuant to the Company’s adoption of a stockholders rights plan that provides that each share of Common Stock issued upon conversion of the Securities at any time
prior to the distribution of separate certificates representing rights will be entitled to receive the right (a “Stockholder Rights Plan”); 
 (b) the distribution of separate certificates representing the rights under a Stockholder Rights Plan; 
 (c) the exercise or redemption of the rights in accordance with any rights agreement under a Stockholder Rights Plan; 
 (d) the termination or invalidation of the rights under a Stockholder Rights Plan; 

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

(f) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future
employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 
 (g) upon the
issuance of any shares of Common Stock pursuant to any option, warrant or right or exercisable, exchangeable or convertible security not described in clause (f) above and outstanding as of the date the Securities were first issued; 

(h) ordinary course of business stock repurchases that are not tender offers or exchange offers referred to in Section 10.10,
including structured or derivative transactions pursuant to a stock repurchase program approved by the Board of Directors; 
 (i)
for a change in the par value of Common Stock; 
 (j) any accrued and unpaid interest (including Additional Interest); or

 (k) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or
convertible security outstanding as of the date the Securities were first issued. 

  
 50 









 If any event described in Section 10.11(a) through (d) occurs, Holders will
receive the rights upon conversion, unless, prior to any conversion, the rights have separated from the Common Stock. If the rights have separated, the Conversion Rate will be adjusted at the time of separation as provided by this Indenture (subject
to readjustment in the event of the expiration termination or redemption of such rights). 
 Notwithstanding the foregoing, no
adjustment need be made to the Conversion Rate pursuant to Section 10.06, 10.07, 10.08, 10.09 or 10.10 if Holders participate (as a result of holding Securities, and at the same time as Common Stock holders participate), subject to notice of
such participation to Holders, in the transaction that would otherwise trigger the applicable adjustment, as if such Holders held a number of shares of Common Stock equal to the then applicable Conversion Rate, multiplied by the principal amount
(expressed in thousands) of Securities held by such Holders, without having to convert. No adjustment need be made if the Common Stock to be issued upon conversion will actually receive the consideration provided in, or be subject to, the
transaction that would otherwise trigger the adjustment. 
 No adjustment need be made for a change in the par value or no par
value of the shares of Common Stock. 
 Section 10.12 Notice of Adjustment. Whenever the Conversion Rate is
adjusted, the Company shall promptly or within three Business Days mail to Holders a notice of the adjustment. The Company shall file with the Trustee and the Conversion Agent such notice briefly stating the facts requiring the adjustment and the
manner of computing it. The notice of adjustment shall be conclusive evidence that the adjustment is correct. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such notice of adjustment except
to exhibit the same to any Holder desiring inspection thereof. 
 Section 10.13 Voluntary Increase. From time to
time, the Company may (but is not required to) increase the Conversion Rate, as permitted by law, and if the Board of Directors determines that such increase would be in the Company’s best interest, by any amount at any time for at least 20
Business Days, so long as the increase is irrevocable during such period. In addition, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase
Common Stock in connection with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased, the Company shall mail to Holders and file with the Trustee and the Conversion Agent a
notice of the increase. The Company shall mail the notice at least 15 days before the date the increased Conversion Rate takes effect. The notice shall state the increased Conversion Rate and the period it will be in effect. A voluntary increase of
the Conversion Rate does not change or adjust the Conversion Rate otherwise in effect for purposes of Section 10.06, 10.07, 10.08 or 10.09. 
 Section 10.14 Notice of Certain Transactions. If: 
 (a) the Company
takes any action that would require an adjustment in the Conversion Rate pursuant to Section 10.06, 10.07, 10.08, 10.09 or 10.10 (unless no adjustment is to occur pursuant to Section 10.11); or 

  
 51 









 (b) the Company takes any action that would require a supplemental indenture pursuant to
Section 10.15; or 
 (c) there is a liquidation or dissolution of the Company, 

then the Company shall mail to Holders and file with the Trustee and the Conversion Agent a notice stating the proposed record date for a dividend,
distribution or subdivision or the proposed effective date of a combination, reclassification, consolidation, merger, binding share exchange, transfer, liquidation or dissolution. The Company shall file and mail the notice at least 15 Scheduled
Trading Days before such date. Failure to file or mail the notice or any defect in it shall not affect the validity of the transaction. 
 Section 10.15 Effect of Reclassification, Consolidation, Merger or Sale. Upon the occurrence of (i) any reclassification of the outstanding shares of Common Stock (other than a
change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or combination covered by Section 10.06), (ii) any transaction involving the Company subject to
Section 5.01 (other than a sale of all or substantially all of the assets of the Company in a transaction in which the holders of Common Stock immediately prior to such transaction do not receive securities, cash or other assets of the Company
or any other Person), (iii) a binding share exchange which reclassifies or changes the outstanding shares of Common Stock, or (iv) any sale or conveyance of all or substantially all of the property and assets of the Company to any other
Person, in each case as a result of which the holders of Common Stock shall be entitled to receive cash, securities or other property or assets with respect to or in exchange for such Common Stock (any such event, a “Merger Event”),
then: 
 (a) the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental
indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) and which shall provide that Holders shall be entitled
thereafter to convert their Securities into the type and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of our Common Stock equal to the
Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”) upon such Merger Event; provided that, at and after the effective time of any such transaction,
any amount otherwise payable in cash for fractional shares of Common Stock upon conversion of the Notes will continue to be payable as described in Section 10.03. 
 (b) In the event the Company shall execute a supplemental indenture pursuant to this Section 10.15, the Company shall promptly file with the Trustee an Officers’ Certificate briefly describing
the Merger Event and stating the type or amount of cash, securities, property or other assets that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent to
such Merger Event under this Indenture have been complied with. Promptly, following the effective time of any such Merger Event, the Company shall notify all Holders of the Securities and make available on its website information describing the type
or amount of cash, securities, property or other assets that will comprise the Reference Property after any such Merger Event. Any failure to deliver such 

  
 52 









 
Officers’ Certificate or make such information available on the Company’s website shall not affect the legality or validity of such supplemental indenture. 

(c) With respect to each $1,000 principal amount of Securities surrendered for conversion after the effective date of any such Merger
Event in lieu of shares of Common Stock otherwise provided for hereunder, the Company shall deliver to the converting Holder a number of units of Reference Property (each such unit comprising the kind and amount of shares of stock, securities or
other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration) equal to
(1) the aggregate principal amount of Securities to be converted, divided by $1,000, multiplied by (2) the then-applicable Conversion Rate; 
 (A) The Company will deliver the cash in lieu of fractional units of Reference Property as set forth pursuant to Section 10.03 (provided that the amount of such cash shall be determined as if
references in such Section to “the Closing Sale Price of a full share of Common Stock” were instead a reference to “the fair market value of a unit of Reference Property” composed of the type and amount of shares of stock,
securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average
Consideration). 
 (B) For purposes of this Section 10.15 , the “Weighted Average Consideration” means the
weighted average of the types and amounts of consideration received by the holder of the Common Stock entitled to receive cash, securities or other property or assets with respect to or in exchange for such Common Stock in any Merger Event who
affirmatively make such an election. 
 (C) The Company shall notify the Holders and the Trustee of the Weighted Average
Consideration as soon as practicable after the Weighted Average Consideration is determined. 
 (d) The above provisions of this
Section shall similarly apply to successive Merger Events. In the event that Securities become convertible into Reference Property pursuant to this Section 10.15, the Company shall notify the Trustee and issue a press release containing the
relevant information and make such press release available on the Company’s website. 
 Section 10.16 Company
Determination Final. Any determination and/or calculation that the Company or the Board of Directors must make pursuant to Sections 10.03, 10.06, 10.07, 10.08, 10.09, 10.10, 10.11 or 10.15 shall be made in good faith and, absent manifest
error, shall be final and binding on the Holders of the Securities. 
 Section 10.17 Trustee’s Adjustment
Disclaimer. The Trustee has no duty to determine when an adjustment under this Article 10 should be made, how it should be made or what it should be. The Trustee shall not be accountable for and makes no representation as to the validity
or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for the Company’s failure to comply with this Article 10. Each Conversion Agent shall have the same protection under this
Section 10.17 as the Trustee.

 Section 10.18 Simultaneous Adjustments. In the event that this Article 10
requires adjustments to the Conversion Rate under more than one of Sections 10.06, 10.07, 10.08 or 10.09, and the Ex-Dividend Dates (or, in the case of a Spin-off, the effective date of such a Spin-off) for the distributions giving rise to such
adjustments shall occur on the same date, then such adjustments shall be made by the Company or the Board of Directors in good faith manner. 
 Section 10.19 Successive Adjustments. After an adjustment to the Conversion Rate under this Article 10, any subsequent event requiring an adjustment under this Article 10 shall cause an
adjustment to the Conversion Rate as so adjusted. 
 Section 10.20 Limitation on Adjustments. The Company
shall not take any action that would result in an adjustment pursuant to the foregoing provisions in this Article 10 if that adjustment would reduce the Conversion Price below the then par value of the shares of Common Stock issuable upon conversion
of the Securities. In no event will the Conversion Rate be decreased other than as a result of a transaction described in Section 10.06(c). 
 Section 10.21 Adjustment to Conversion Rate Upon Certain Transactions. If, after the Issue Date, a Fundamental Change pursuant to Paragraphs (i), (ii) or (iv) of the
definition of Fundamental Change set forth in Section 3.04, which, after giving effect to any exceptions or exclusions from such definition set forth in Section 3.04(a) but with respect to any event described in Paragraph (ii) of the
definition of Fundamental Change, shall be determined without regard to the exception provided by Section 3.04(a)(ii)(B) (any such event, a “Make Whole Adjustment Event”), occurs, and if a Holder elects to convert its
Securities in connection with such Make Whole Adjustment Event (any conversion during the period begging with, and including, the Make Whole Adjustment Event Effective Date to, and including, the second Scheduled Trading Day immediately preceding
the Fundamental Change Repurchase Date or, if there is no Fundamental Change Repurchase Date, the 35th Scheduled Trading Day immediately following the Make Whole Adjustment Event Effective Date, as the same may be, will be deemed to be “in connection with” such Make Whole Adjustment Event), the
Company will increase the applicable Conversion Rate for the Securities surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described in this Section 10.21. 

The Company shall mail Holders and the Trustee, not later than the Make Whole Adjustment Event Effective Date (as defined below) of such
Make Whole Adjustment Event, a notice describing the Make Whole Adjustment Event and the Holders’ rights to Additional Shares. The Company shall provide notice to Holders and the Trustee, and make such information available on its website as
soon as practicable after it first determines the anticipated Make Whole Adjustment Event Effective Date. 
 The number of
Additional Shares will be determined by reference to the table below and is based on the date on which such Make Whole Adjustment Event transaction occurs or becomes effective (the “Make Whole Adjustment Event Effective Date”) and
the price paid per share of Common Stock in such Make Whole Adjustment Event (the “Share Price”). If the holders of Common Stock receive only cash in the Make Whole Adjustment Event described in Section 3.04(a)(ii), the Share
Price shall be the cash amount paid per share of Common Stock. Otherwise, the Share Price shall be the average of the Closing Sale Prices of the Common Stock 

  
 54 









 
on the ten consecutive Trading Days up to but excluding the Make Whole Adjustment Event Effective Date. 
 The table below sets forth the Share Price paid per share for Common Stock in the Make Whole Adjustment Event and the number of Additional Shares per $1,000 principal amount of the Securities by which the
Conversion Rate will be increased. The Share Prices set forth in the Share Price column of the table will be adjusted as of any date on which the Conversion Rate is adjusted. The adjusted Share Prices will equal the Share Prices applicable
immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the applicable Conversion Rate immediately prior to the adjustment giving rise to the Share Price adjustment and the denominator of which is the applicable
Conversion Rate as so adjusted.

 If the exact Share Prices and Make Whole Adjustment Event Effective Dates are not set forth in the table,
then: (i) if the Share Price is between two Share Price amounts in the table or the Make Whole Adjustment Event Effective Date is between two dates in the table, the Additional Shares issued upon conversion of the Securities will be determined
by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Share Price amounts and the two Make Whole Adjustment Event Effective Dates in the table, based on a 365-day year; (ii) if the Share
Price exceeds $[•] per share, subject to adjustment as set forth herein, no Additional Shares will be issued upon conversion of the Securities; and (iii) if the Share Price is less than $[•] per share, subject to adjustment as set
forth herein, no Additional Shares will be issued upon conversion of the Securities. 
 Notwithstanding the foregoing, in no
event will the total number of shares of Common Stock issuable upon conversion exceed [•] shares for each $1,000 principal amount of Securities, subject to adjustments in the same manner as the Conversion Rate pursuant to Article 10.

 The Company will settle conversions of Securities converted in connection with a Make Whole Adjustment Event as provided in
Section 10.01; provided, however that in connection with a Make Whole Adjustment Event in which holders of Common Stock receive only cash consideration for their shares of Common Stock (in a single per-share amount, other than
with respect to appraisal and similar rights), the Company shall settle conversions by delivering, on the tenth Business Day after the Conversion Date, for each $1,000 principal amount of Securities, an amount of cash equal to (i) the
applicable Conversion Rate on the Conversion Date, increased by Additional Shares, if any, calculated as set forth in this Section 10.21, multiplied by (ii) the per-share amount of cash consideration paid in such Make Whole Adjustment
Event.

 ARTICLE 11 
 PAYMENT OF INTEREST 
 Section 11.01 Payment of Interest.

 (a) The Company shall pay interest on the Securities at a rate of [•]% per annum, payable semi-annually in arrears
on [•] and [•] of each year (each, an “Interest Payment Date”) or, if any such day is not a Business Day, the immediately following Business Day, commencing [•], 2013. Interest on a Security shall be paid to the
Holder of such Security at the Close of Business on [•] or [•] (each, a “Record Date”), as the case may be, next preceding the related Interest Payment Date, and shall be computed on the basis of a 360-day year comprised
of twelve 30-day months. In the event of the maturity, conversion, or purchase of a Security by the Company at the option of the Holder, interest shall cease to accrue on such Security. 

(b) Upon conversion of a Security, (i) a Holder shall not receive any cash payment of interest (unless such conversion occurs between
a Record Date and the Interest Payment Date to which it relates, in which case a Holder on the Record Date will receive on the Interest Payment Date accrued and unpaid interest) and the Conversion Rate shall not be adjusted to account for accrued
and unpaid interest and (ii) except as set forth in clause (c) below, the Company’s delivery to a holder of shares of Common Stock into which the Security is convertible shall be deemed to satisfy its obligation with respect to such
Security, and any accrued but unpaid interest shall be deemed to be paid in full upon conversion, rather than cancelled, extinguished or forfeited. 
 (c) Securities surrendered for conversion by a Holder after the Close of Business on any Record Date but prior to the next Interest Payment Date, must be accompanied by payment of an amount equal to the
interest that the Holder is to receive on the next Interest Payment Date for the Securities; provided, however, that no such payment need be made (1) if the Company has specified a Fundamental Change Repurchase Date that is after
a Record Date and on or prior to the next Interest Payment Date; (2) to the extent of overdue interest, if any overdue interest exists at the time of conversion with respect to such Securities; or (3) if the Securities are surrendered for
conversion after the Close of Business on the Record Date for the payment of interest on the Securities at the Maturity Date. 

Section 11.02 Defaulted Interest. Any installment of interest that is payable, but is not punctually paid or duly provided
for on any Interest Payment Date, shall forthwith cease to be payable to the Holders in whose names the Securities were registered on the Record Date applicable to such installment of interest. Any overdue installments of interest, and interest on
any Defaulted Amounts (together, the “Defaulted Interest”) (including any interest on such Defaulted Interest), may be paid by the Company, at its election, as provided in this Section 11.02 (a) or (b). 

(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 Securities 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


  
 56 









 
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 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 as provided in this Section 11.02(a). Thereupon the Trustee shall fix a Special Record Date for the payment of 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 and the Special Record Date therefor to be sent, 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 and the Special Record
Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Holders in whose names the Securities are registered at the Close of Business on such Special Record Date and shall no longer be payable pursuant to
Section 11.02(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 Securities 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 11.02(b), such manner of payment shall be deemed practicable by the Trustee. 
 Section 11.03 Interest Rights Preserved. Subject to the foregoing provisions of this Article 11 and Section 2.06, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 

Section 11.04 Overdue Principal and Interest. The Company shall (A) pay interest on overdue principal on any Securities
(including, without limitation, the Fundamental Change Repurchase Price, if applicable) and (B) to the extent lawful, pay interest on overdue installments of interest (without regard to any applicable grace periods) (any such overdue principal
and interest, “Defaulted Amounts”). Interest shall accrue on any Defaulted Amounts at the rate of interest borne by the Securities, plus one percent from, and including, the relevant payment date to, but excluding, the date on which
such Defaulted Amounts shall have been paid by the Company. Such interest on Defaulted Amounts shall be computed on the basis of a 360-day year comprised of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed.
