CONVERTIBLE PROMISSORY NOTE 
  

			
	$000	  	 October    , 2013

San Diego, California

 For value received Sorrento Therapeutics, Inc., a Delaware corporation (“Payor” or the
“Company”) promises to pay to                 or its assigns (“Holder”) the principal sum of $000 with simple interest
on the outstanding principal amount at the rate of 7% per annum. Interest shall commence with the date hereof and shall continue on the outstanding principal until paid in full or converted. Interest shall be simple interest computed on the
basis of a year of 365 days for the actual number of days elapsed and shall accrue and be payable on the earlier of (a) the date the amount of accrued interest on the principal amount is converted in accordance with Section 2, or
(b) the Maturity Date set forth in Section 3. 
 1. Payments. All payments of interest and principal shall be in lawful
money of the United States of America. All payments shall be applied first to accrued interest, and thereafter to principal. 
 2.
Conversion. 
 (a) Mandatory Conversion. In the event that Payor issues and sells shares of its Equity Securities to investors
(the “Investors”) after the date hereof and on or before the Maturity Date in an equity financing with total proceeds to the Payor of not less than $10,000,000 (excluding the conversion of the Notes or other debt) (a
“Qualified Financing”), then the outstanding principal balance of this Note shall automatically convert in whole without any further action by the Holder into such Equity Securities at a conversion price equal to the price
per share paid by the Investors purchasing the Equity Securities on the same terms and conditions as given to the Investors in the Qualified Financing. Any unpaid accrued interest on this Note shall be converted into Equity Securities on the same
terms as the principal of the Notes. For purposes of this Note, the term “Equity Securities” shall mean the Payor’s Common Stock or any securities conferring the right to purchase the Payor’s Common Stock or
securities convertible into, or exchangeable for (with or without additional consideration), the Payor’s Common Stock (excluding the Notes and the Warrants), in each case issued in the Qualified Financing following the date hereof, except that
such defined term shall not include any security 

  
 1. 

 
granted, issued and/or sold by the Payor to any employee, director or consultant in such capacity. For clarity, if the shares of Common Stock are issued together with warrants or other
securities, then the term Equity Securities shall mean the shares of Common Stock of Payor together with such warrants or other securities purchased by the Investors. 

(b) Voluntary Conversion. At any time after November 30, 2013 and until this Note is no longer outstanding, the principal amount
under this Note shall be convertible, in whole or in part, into shares of Common Stock at the option of the Holder, at any time and from time to time upon written notice to the Payor. The Holder shall effect conversions by delivering to Payor a
written notice of conversion, which notice shall be irrevocable, specifying in such notice the principal amount of this Note to be converted and the date on which such conversion shall be effected. The principal amount of this Note shall be
converted based upon the ten (10) trading day volume weighted average closing price of the Common Stock for the trading days immediately prior to the date of receipt of notice of voluntary conversion. Any conversions pursuant to this
Section 2(b) shall be subject to physically surrendering this Note to Payor, and Payor shall issue a replacement Note in the amount of any remaining unconverted principal amount, if any, contemporaneously with the issuance of the shares of
Common Stock issued in the conversion. 
 3. Maturity Date. Unless this Note has been converted in accordance with the terms of
Section 2 above, the entire outstanding principal balance and all unpaid accrued interest shall become fully due and payable on April 15, 2017 (the “Maturity Date”). 

4. Prepayment. Payor may prepay this Note prior to the Maturity Date without penalty or interest upon written notice to the Holder. 

5. Events of Default. If there shall be any Event of Default hereunder, at the option and upon the declaration of the Holder of this
Note and upon written notice to the Payor (which election and notice shall not be required in the case of an Event of Default under Section 6(c) or 6(d)), this Note shall accelerate and all principal and unpaid accrued interest shall become due
and payable. The occurrence of any one or more of the following shall constitute an “Event of Default”: 
 (a) Payor fails
to pay timely any of the principal amount due under this Note on the date the same becomes due and payable or any accrued interest or other amounts due under this Note on the date the same becomes due and payable; 

(b) Payor shall default in its performance of any covenant under the Note; 

(c) Payor files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other law
for the relief of, or relating to, debtors, now or hereafter in effect, or makes any assignment for the benefit of creditors or takes any corporate action in furtherance of any of the foregoing; or 

(d) An involuntary petition is filed against Payor unless such petition is dismissed or discharged within sixty (60) days under any
bankruptcy statute now or hereafter in effect, or a custodian, receiver, trustee, assignee for the benefit of creditors (or other similar official) is appointed to take possession, custody or control of any property of Payor. 

  
 2. 

 6. Waiver. Payor hereby waives demand, notice, presentment, protest and notice of
dishonor. 
 7. Adjustments for Stock Dividends and Stock Splits. If Payor, at any time while this Note is outstanding: (a) pays
a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by Payor upon conversion of the
Notes), (b) subdivides outstanding shares of Common Stock into a larger number of shares, (c) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (d) issues, in
the event of a reclassification of shares of the Common Stock, any shares of capital stock of Payor, then the conversion price set forth in Section 2 shall be proportionately adjusted to reflect the change from the number of shares applicable
prior to such event to the corresponding number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section 7 shall become effective as of the record date for the determination of
stockholders entitled to receive such dividend, distribution, subdivision, combination or reclassifcation. 
 8. Governing Law. This
Note shall be governed by and construed under the laws of the State of California, as applied to agreements among California residents, made and to be performed entirely within the State of California, without giving effect to conflicts of laws
principles 
 9. Subordination. The indebtedness evidenced by this Note is subordinated in right of payment to the prior payment in
full of any Senior Indebtedness. “Senior Indebtedness” shall mean all amounts due in connection with (a) indebtedness of Payor to banks or other lending institutions regularly engaged in the business of lending money and
(b) any such indebtedness or any debentures, notes or other evidence of indebtedness issued in exchange for such Senior Indebtedness, or any indebtedness arising from the satisfaction of such Senior Indebtedness by a guarantor, including
indebtedness owing to Oxford Finance LLC and Silicon Valley Bank, and their respective successors and assignees. 
 10. Covenant.
Payor covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of this Note as herein provided, free from preemptive rights or any other
actual contingent purchase rights of persons other than the Holder (and the other holders of the Notes), not less than such aggregate number of shares of the Common Stock as shall be issuable upon the conversion of the then outstanding principal
amount of this Note. Payor covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable. 

11. Amendments. Any term of this Note may be amended or waived only with the written consent of Payor and the Holder. 

12. Transferability. This Note may be not be transferred by the Holder without the prior written consent of the Company

as herein otherwise 

  
 7 

 
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. 

(a) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such

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. The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a part of this Indenture, and the Company and the Trustee, by their execution and delivery of this Indenture, expressly
agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Security conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. 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. 

  
 9 

 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). 
 (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 an Opinion of Counsel as to such matters as the Trustee may reasonably request, 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. Securities shall be
dated the date of their authentication. 
 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. 

  
 10 

 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, 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 its Corporate Trust 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. 

  
 11 

 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. 

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. 

  
 12 

 
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. 

(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 

  
 13 

 
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. 
 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. 

  
 14 

 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 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. 

  
 15 

 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 

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 

  
 16 

 
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 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. 

  
 17 

 (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. Neither the Trustee nor any Agent shall have the responsibility for any actions taken or not taken by the Depositary. 

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 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 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 and that reliance may be placed only on the other identification numbers printed on the Securities, and any such notice shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in the
event of any change in the CUSIP 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.

 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 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 

  
 19 

 
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 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; 

  
 20 

 (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 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;

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; 

  
 21 

 (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. 

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 
 (c) the principal amount, if any, of such Security which remains
subject to the original Fundamental Change Repurchase Notice. 
 If the Securities are held in book entry form, the notices must also comply with the
appropriate procedures of DTC. 
 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. 
 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. 

  
 23 

 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

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.

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

(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

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 such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or

(c) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that such consolidation,
merger, conveyance, transfer, sale or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article 5 and that all conditions precedent herein provided for relating to
such transaction have been satisfied, and an Opinion of Counsel that any supplemental indenture is a valid and binding obligation of the Company or successor, as applicable. 

The successor Person formed by such consolidation or into which the Company is merged or the successor Person to which such conveyance,
transfer, sale or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, the
Company shall be discharged from all obligations and covenants under 

  
 26 

 
this Indenture and the Securities. Subject to Section 9.06, the Company, the Trustee and the successor Person shall enter into a supplemental indenture to evidence the succession and
substitution of such successor Person and such discharge and release of the Company. 
 ARTICLE 6 

DEFAULTS AND REMEDIES 

Section 6.01 Events of Default. Each of the following events shall be an “Event of Default”: 

(a) the Company defaults in any payment of interest (including Additional Interest) due and payable on the Securities, and such default
continues for a period of 30 days; 
 (b) [Reserved]; 

(c) the Company defaults in the payment of all or any part of the principal on the Securities and accrued and unpaid interest when the same
becomes due and payable at its Maturity Date, upon required repurchase following a Fundamental Change; 
 (d) the Company fails to provide a
Fundamental Change Notice or a notice of a Make Whole Adjustment Event; 
 (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; 

(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 

  
 27 

 
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 

(j) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(i) is for relief against the Company in an involuntary case; 

(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. 

  
 28 

 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, 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 an Officers’ 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 an Officers’ Certificate setting forth the particulars of such payment. 

  
 29 

 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 

  
 30 

 
Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to 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 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. To the extent that the payment of any such compensation, expenses, disbursements and advances 

  
 31 

 
of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of
reorganization or arrangement or otherwise; for the avoidance of doubt, such a lien shall not be extended in any manner that would conflict with the Company’s obligations to its other creditors. 

Section 6.10 Priorities. If the Trustee (including any predecessor 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. 

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 (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein). 
 (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. 
 (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. The Trustee shall not be required to give any bond or surety in respect of the
performance of its powers or duties hereunder. 

  
 33 

 (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 from Holders of at least 25% of the aggregate principal amount of the Securities sent to the Trustee in accordance with Section 12.02, and such notice reference the Securities and this
Indenture 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, or to establish matters, it may require an Officers’
Certificate or an Opinion of Counsel or both. 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. Any request, demand, notice or direction of the
Company shall be sufficiently evidence by an Officers’ Certificate or by a Company Order, or signed by a Company Officer, and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution. 

(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. 
 (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 

  
 34 

 
Indenture, unless such Holders shall have offered to the Trustee security or indemnity 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. 

(j) In no event shall the Trustee be responsible or liable for any special, indirect, punitive or consequential loss or damage of any kind
whatsoever (including, but not limited to, loss of profit), irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

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). 

  
 35 

 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 Indenture 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)
in connection with the exercise of its rights or powers. 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. 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. 
 “Trustee” for the purposes of this Section 7.07 shall include any predecessor
Trustee and the Trustee in each of its capacities hereunder and each agent, custodian and other person employed to act hereunder; provided, however, that the negligence or willful misconduct of any Trustee hereunder shall not affect
the rights of any other Trustee hereunder. 

  
 36 

 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: 
 (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 

  
 37 

 
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.

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. 

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

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. 

  
 40 

 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. 
 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 Company Order together with a Board Resolution and evidence of the consents of Holders if applicable, 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 supplement or amendment is authorized or permitted by this Indenture, and an Opinion of Counsel
stating that such supplement or amendment is a valid and binding obligation of the Company. 

  
 41 

 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. 

  
 42 

 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. 

  
 43 

 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 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: 

 

									
		 	CR’ = CR	 	×	 	OS	 	
		 	 	 	OS’	 	

 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 

  
 44 

 
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 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: 
  

									
		 	CR’ = CR	 	×	 	(O + N)	 	
		 	 	 	O+((N × P)/M)	 	

 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 plus the per share consideration (if any) the Company receives for such rights, options or warrants; 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

  
 45 

 
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. 
 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

  
 46 

 
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 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’ = CR	 	×	 	F+MP	 	
		 	 	 	MP	 	

  

			
	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 conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 

  
 47 

 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 

  
 48 

 
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’ = CR	 	×	 	SP	 	
		 	 	 	SP – C	 	

  

			
	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. 

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’ = CR	 	×	 	F + (SP × OS’)	 	
		 	 	 	OS × SP	 	

  

			
	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. 

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. 

  
 50 

 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. 
 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). 

  
 51 

 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 
 (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 

  
 52 

 
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 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 

  
 53 

 
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. 

  
 54 

 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 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 

  
 55 

 
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 $125.00 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 $46.54 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 21.4868 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 2.75% per annum, payable semi-annually in arrears on May 1 and
November 1 of each year (each, an “Interest Payment Date”) or, if any such day is not a Business Day, the immediately following Business Day, commencing May 1, 2014. Interest on a Security shall be paid to the Holder of
such Security at the Close of Business on April 15 or October 15 (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 

  
 57 

 
Interest (a “Special Record Date”), which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest 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 Company 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 Company shall promptly notify the Trustee of such Special Record Date and, in the name and at the expense of the Company, the Trustee 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.

 [FORM OF REVERSE OF SECURITY] 

2.75% Convertible Senior Notes due 2018 
 1.
Interest 
 This Security shall bear cash interest at the rate of 2.75% per annum. Interest on this Security shall accrue from
October 21, 2013 (the “Issue Date”) or from the most recent date to which interest has been paid or provided for. Interest shall be payable semiannually in arrears on May 1 and November 1 of each year, beginning on
May 1, 2014, to the holder of record of Securities at the Close of Business on the April 15 or October 15 immediately preceding such Interest Payment Date (or repurchase or Maturity Date, as applicable). Each payment of cash interest
on this Security shall include interest accrued for the period commencing on and including the immediately preceding Interest Payment Date (or, if none, the Issue Date) through the day before the applicable Interest Payment Date, Fundamental Change
Repurchase Date or Maturity Date, as applicable. Any payment required to be made on any day that is not a Business Day shall be made on the next succeeding Business Day and no interest or other amount will be paid as a result of any such
postponement. Interest shall be calculated using a 360-day year composed of twelve 30-day months. Interest shall cease to accrue on this Security upon its Maturity Date, conversion or repurchase by the Company, including a repurchase at the option
of the Holder upon a Fundamental Change in accordance with Paragraph 6 hereof.  
 Interest on Securities converted after a Record
Date, but prior to the corresponding Interest Payment Date, will be paid to the Holder of the Securities on the Record Date, but upon such conversion, the Holder must pay the Company the interest which has accrued and will be paid by the Company on
such Interest Payment Date. 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 such 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. 
 2. Method of Payment. 

The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided herein and in the Indenture.
The Company will pay interest (except Defaulted Interest) on the principal amount of the Securities on each May 1 and November 1 to the Persons who are registered Holders of Securities at the Close of Business on the April 15 and
October 15 next preceding the Interest Payment Date even if Securities are canceled or repurchased after such Record Date and on or before the Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect principal
payments. The Company will pay principal, accrued and unpaid interest (including Additional Interest), if any, and any payment of the Fundamental Change Repurchase Price or premium in money of the United States that at the time of payment is legal
tender for payment of public and private debts. The Company will make all payments in respect of a Global Security registered in the name of the Depositary or its nominee to the Depositary or its nominee, as the case may be, by wire transfer of
immediately available funds to the account specified by such Holder. The Company will make all payments in 

  
 A-3 

 
respect of a Certificated Security (including principal and interest) in U.S. dollars at the office of the Trustee. At the Company’s option, the Company may make such payments by mailing a
check to the registered address of each Holder thereof as such address shall appear on the register or, if requested by a Holder of more than $1,000,000 in aggregate principal amount of Securities, by wire transfer of immediately available funds to
the account specified by such Holder. If an Interest Payment Date is a date other than a Business Day, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period. 

3. Paying Agent, Conversion Agent and Registrar. 

Initially, Wells Fargo Bank, National Association, will act as Trustee, Paying Agent, Conversion Agent and Registrar. The Company may appoint
and change any Paying Agent, Conversion Agent or Registrar without notice, other than notice to the Trustee; provided that the Company will maintain at least one Paying Agent in the United States of America, which shall initially be an office
or agency of the Trustee. The Company or any of its Subsidiaries or any of their affiliates may act as Paying Agent, Conversion Agent or Registrar. 
 4.
Indenture. 
 The Company issued the Securities under an Indenture dated as of October 21, 2013 (the “Indenture”),
between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect from time to time (the “TIA”).
Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of those terms. 

The Securities are general senior unsecured obligations of the Company. The Indenture does not limit other indebtedness of the Company,
secured or unsecured. 
 5. [Reserved] 
 6. Purchase By the
Company at the Option of the Holder upon a Fundamental Change. 
 (a) At the option of the Holder, and subject to the terms and conditions
of the Indenture, if a Fundamental Change occurs, each Holder of Securities will have the right, at its option, to require the Company to repurchase for cash all of its Securities, or any portion of the principal amount thereof that is equal to
$1,000 or an integral multiple of $1,000, at a Fundamental Change Repurchase Price equal to 100% of the principal amount of Securities to be repurchased plus accrued and unpaid interest (including Additional Interest), if any, to (but excluding) the
Fundamental Change Repurchase Date. To exercise the repurchase right, the Holder must deliver, on or before the Close of Business on the Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date, written notice to the
Trustee of such Holder’s exercise of its repurchase right, together with the Securities with respect to which the right is being exercised. Subject to such Holder’s satisfaction of certain requirements in the Indenture, the Company is
required to repurchase the Securities on 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. 

  
 A-4 

 (b) Holders have the right to withdraw any Fundamental Change Repurchase Notice delivered
pursuant to Paragraph 6(a) above by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture at any time prior to the Close of Business on the last day prior to the Fundamental Change
Repurchase Date. If cash sufficient to pay the Fundamental Change Repurchase Price of all Securities or portions thereof to be repurchased as of the Fundamental Change Repurchase Date is deposited with the Paying Agent on the Fundamental Change
Repurchase Date, interest will cease to accrue on such Securities (or portions thereof) immediately after such Fundamental Change Repurchase Date, and the Holder thereof shall have no other rights as such other than the right to receive the
Fundamental Change Repurchase Price upon surrender of such Security. 
 7. Conversion. 

(a) Holders may surrender Securities, in integral multiples of $1,000 principal amount, for conversion into shares of Common Stock until the
second Scheduled Trading Day immediately preceding the Maturity Date. 
 (b) The initial Conversion Rate is 16.2165 shares of Common
Stock per $1,000 principal amount, subject to adjustment in certain events described in the Indenture. 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 in effect on the relevant Conversion Date; provided, however, that for any conversion that occurs on or after the record date for the payment of interest on the
Securities at maturity, the Company will deliver such shares on the Maturity Date. Notwithstanding the foregoing, the Company will not deliver any fractional shares upon conversion; instead, Holders will receive cash in lieu of fractional shares
based on the Closing Sale Price of the Common Stock on the Conversion Date (or, if the Conversion Date is not a Trading Day, the next following Trading Day).  

(c) To surrender a Security for conversion, a Holder must (1) complete and manually sign the irrevocable conversion notice below (or
complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent; (2) surrender the Security to the Conversion Agent; (3) furnish appropriate endorsements and transfer documents; and (4) pay any
transfer or similar tax, if required. 
 (d) A Holder may convert a portion of a Security if the principal amount of such portion is $1,000
or an integral multiple of $1,000. No payment or adjustment will be made for dividends on the shares of Common Stock, except as provided in the Indenture. Except as provided in Paragraph 1 hereof, on conversion of a Security, the Holder will not
receive any cash payment representing accrued and unpaid interest with respect to the converted Securities. Instead, upon conversion the Company will deliver to the Holder shares of Common Stock and any cash payment to account for fractional shares.
Accrued and unpaid interest will be deemed paid in full rather than cancelled, extinguished or forfeited. The Company will not adjust the Conversion Rate to account for accrued and unpaid interest. 

  
 A-5 

 8. Denominations; Transfer; Exchange. 

The Securities are in fully registered form, without coupons, in denominations of $1,000 of principal amount and integral multiples of $1,000.
A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or
permitted by the Indenture. The Registrar need not transfer or exchange any Securities in respect of which a Fundamental Change Repurchase Notice has been given and not withdrawn (except, in the case of a Security to be repurchased in part, the
portion of the Security not to be repurchased). 
 9. Persons Deemed Owners. 

The registered Holder of this Security may be treated as the owner of this Security for all purposes. 

10. Unclaimed Money or Securities. 
 The Trustee
and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property
law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors, unless an applicable abandoned property law designates another Person. 

11. Trustee Dealings with the Company. 
 Subject
to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its
affiliates and may otherwise deal with the Company or its affiliates with the same rights it would have if it were not Trustee. 
 12. Calculations in
Respect of Securities. 
 The Company will be responsible for making all calculations called for under the Securities. These calculations
include, but are not limited to, determinations of the market prices of the Securities and the Common Stock and any accrued interest payable on the Securities. 

The Company will make these calculations in good faith and, absent manifest error, the calculations will be final and binding on Holders of
the Securities. The Company will provide to the Trustee a schedule of its calculations, and the Trustee is entitled to rely upon the accuracy of such calculations without independent verification. The Trustee will forward the Company’s
calculations to any Holder of the Securities upon the request of such Holder. 

  
 A-6 

 13. No Recourse Against Others. 

A director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under
the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities. 
 14. Authentication. 

This Security shall not be valid until an authorized signatory of the Trustee manually signs the Trustee’s certificate of authentication
on the other side of this Security. 
 15. Abbreviations. 

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 

16. GOVERNING LAW. 
 THE INDENTURE AND THE
SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION
WOULD BE REQUIRED THEREBY. 
 17. Additional Interest. 

Holders of Securities shall be entitled to payments of Additional Interest to the extent set forth in the Indenture. 

18. Ranking. 
 The Securities shall be senior
unsecured obligations of the Company and will rank equal in right of payment to any future senior unsecured indebtedness and senior in right of payment to any indebtedness that is contractually subordinated to the Securities. 

The Company will furnish to any Holder, upon written request and without charge, a copy of the Indenture which has in it the text of this
Security in larger type. Requests may be made to:
