“Stock Price” has the meaning specified in Section 4.06(c). 

“Successor Company” has the meaning specified in Section 8.01(a). 

“Supplemental Indenture” has the meaning specified in the first paragraph hereof. 

“Trading Day” means a day on which (i) trading in the Common Stock generally occurs on The New York Stock Exchange
or, if the Common Stock is not then listed on The New York Stock Exchange, on the principal other U.S. national or regional securities exchange on which the Common Stock is then listed or, if the Common Stock is not then listed on a U.S. national or
regional securities exchange, on the principal other market on which the Common Stock is then traded and (ii) a Last Reported Sale Price for the Common Stock is available on such securities exchange or market; provided that if the Common
Stock is not so listed or traded, “Trading Day” means a Business Day; and provided, further, that for purpose of determining amounts due upon conversion pursuant to Section 4.03 only, “Trading
Day” means a day on which (x) trading in the Common Stock generally occurs on The New York Stock Exchange or, if the Common Stock is not then listed on The New York Stock Exchange, on the principal other U.S. national or regional
securities exchange on which the Common Stock is then listed or, if the Common Stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which the Common Stock is then listed or admitted for

Solicitation Agent, then that such one bid shall be used. If the Bid Solicitation Agent cannot reasonably obtain at least one bid for $2,000,000 principal amount of the Notes from a nationally recognized securities dealer on any Trading Day, then
the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate on such Trading Day. If (x) the Company is not
acting as Bid Solicitation Agent, and the Company does not, when required to do so, instruct the Bid Solicitation Agent to obtain bids when required, or if the Company gives

such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate on each
Trading Day such failure continues.

 THE SECURITIES 

Section 2.01. Title and Terms; Payments. There is hereby established a series of Securities designated the “3.00%
Convertible Senior Notes due 2017” initially limited in aggregate principal amount to $450,000,000, which amount shall be as set forth in an Authentication Order for the authentication and delivery of Notes pursuant to Section 2.05 of the
Original Indenture. 
 The principal amount of Notes then outstanding shall be payable on the Maturity Date. Interest on the
Notes shall accrue at a rate of 3.00% per annum, from November 15, 2010 or from the most recent date on which interest has been paid or duly provided for, until the principal thereof is paid or made available for payment. Interest shall be
payable on each Interest Payment Date, beginning on May 15, 2011, to the Person in whose name a Note is registered on the Note 

  
 12 









 
Register at the close of business on the Regular Record Date immediately preceding the applicable Interest Payment Date. If any Interest Payment Date, the Maturity Date or any Fundamental Change
Purchase Date falls on a day that is not a Business Day, the required payment shall be made on the next succeeding Business Day and no interest on such payment shall accrue in respect of such delay. After the occurrence, and during the continuance
of any Event of Default set forth in clause (a) or (b) of Section 5.01, any amounts on any Note (including, without limitation, the Fundamental Change Purchase Price, principal and interest) that are payable but are not punctually
paid or duly provided for shall accrue interest per annum at the rate borne by the Notes plus one percent, subject to the enforceability thereof under applicable law. Interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months. 
 The Company may, without the consent of the Holders of the Notes, hereafter issue
additional Notes (“Additional Notes”) under the Indenture with the same terms and with the same CUSIP number as the Notes issued on the date of this Supplemental Indenture (the “Initial Notes”) in an unlimited
aggregate principal amount; provided that such Additional Notes must be part of the same issue as the Initial Notes for U.S. federal income tax purposes. Any such Additional Notes shall constitute a single series together with the Initial
Notes for all purposes hereunder, including, without limitation, for purposes of any waivers, supplements or amendments to the Indenture requiring the approval of Holders of the Notes and any offers to purchase the Notes. 

The Form of Note shall be substantially as set forth in Exhibit A and the Form of Notice of Conversion, the Form of Fundamental Change
Purchase Notice and the Form of Assignment and Transfer shall be substantially as set forth in Attachments 1, 2 and 3, respectively, to Exhibit A, each of which is incorporated into and shall be deemed a part of this Supplemental Indenture, and in
each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed
thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined to be necessary or appropriate by the Officers of the Company executing such Notes, as evidenced by their execution of the
Notes. 
 The Company shall pay the principal of and interest on any Global Note registered in the name of or held by the
Depositary or its nominee in immediately available funds to the Depositary or its nominee, as the case may be, as the registered Holder of such Global Note. The Company shall pay the principal of any Physical Notes at the office or agency designated
by the Company for that purpose. 

  
 13 









  
 The Company shall pay
interest on any Physical Notes (A) to Holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of such Notes at their address as it appears in the Note Register and (B) to Holders having an
aggregate principal amount of more than $5,000,000, either by check mailed to each such Holder or, upon application by a Holder to the Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that
Holder’s account within the United States, which application shall remain in effect until the Holder notifies the Registrar, in writing, to the contrary. 
 Section 2.02. Book-entry Provisions for Global Notes. (a) The Notes initially shall be issued in the form of one or more Global Notes without interest coupons (i) registered in the
name of Cede & Co., as nominee of the Depositary and (ii) delivered to the Trustee as custodian for the Depositary. 
 Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Supplemental Indenture or the Original Indenture with respect to any Global Note held on
their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and Cede & Co., or such other Person designated by the Depositary as its nominee, may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner of the Global Note 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 impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of any Holder. 

(b) If: (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as Depositary for
the Global Notes and a successor Depositary is not appointed within 60 days; (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor Depositary is not appointed within 60 days; or (iii) an
Event of Default with respect to the Notes has occurred and is continuing and any beneficial owner requests that its Notes be issued as Physical Notes, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate and an
Authentication Order for the authentication and delivery of Notes, will authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note
corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount equal to the
principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note shall be cancelled. Sections 2.09(d) and 2.09(e) of the Original Indenture shall not apply to the Notes, and
shall be superseded in their entirety by this Section 2.02(b).

 (c) The Holder of
Global Notes 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 Supplemental Indenture, Original
Indenture or the Notes. 
 (d) Section 2.09(n) of the Original Indenture shall not apply to the Notes, and shall be
superseded in its entirety by this Section 2.02(d). A legend in substantially the following form shall appear on the face of all Global Notes:

REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS NOTE (OTHER THAN A TRANSFER OF THIS NOTE AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF
THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY) MAY BE REGISTERED EXCEPT IN LIMITED CIRCUMSTANCES. 
 UNLESS THIS NOTE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE
OR PAYMENT, AND ANY NOTE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS
REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 

Section 2.03. Reporting Requirement. The Company shall file with the Trustee within 15 days after the Company is required to
file the same with the SEC (after giving effect to any grace period afforded to the Company pursuant to Rule 12b-25 under the Exchange Act), copies of the annual reports and of the information, documents and other reports (or copies of such portions
of any of the foregoing as the SEC may from time to time by rules and regulations prescribe) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) 

  
 15 









 
of the Exchange Act. Any such document or report that the Company files with the SEC via the EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section 2.03 as of
the time such documents are filed via the EDGAR system. Section 4.03 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 2.03. 

Section 2.04. Purchase and Cancellation. The Company shall cause all Notes surrendered for payment, repurchase (including
required purchase upon the occurrence of a Fundamental Change), registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s Agents, Subsidiaries or Affiliates), to be
delivered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by the Trustee. No Notes shall be authenticated in exchange for any Notes cancelled, as provided herein. The Company may, to the extent
permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, without giving prior notice to Holders, whether by the Company or the Company’s
Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes
repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with this Section 2.04 and any such Notes shall no longer be considered outstanding under the Indenture upon such
repurchase. Any Notes surrendered for cancellation by the Company shall not be reissued or resold. Section 2.13 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 2.04.

 ARTICLE 3 

FUNDAMENTAL CHANGES AND PURCHASES THEREUPON 

Section 3.01. Purchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time,
then each Holder of Notes shall have the right, at such Holder’s option, to require the Company to purchase for cash any or all of such Holder’s Notes, or any portion of the principal amount thereof, that is an integral multiple of $1,000,
on a date (the “Fundamental Change Purchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice, at a purchase price equal
to 100% of the principal amount of the Notes to be purchased pursuant to this Article 3, plus accrued and unpaid interest thereon, if any, to, but excluding, the Fundamental Change Purchase Date (the “Fundamental Change Purchase
Price”), unless the Fundamental Change Purchase Date is after a Regular Record Date and on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of
accrued and unpaid interest, if any, on the Interest Payment Date to the Holders of record as of the preceding Regular Record Date, and the Fundamental Change Purchase Price shall be equal to 100% of the principal amount of the Notes to be purchased
pursuant to this Article 3. 
 To exercise the right to require the Company to purchase its Notes upon a Fundamental Change in
accordance pursuant to this Section 3.01, a Holder must: 
 (i) deliver to the Paying Agent a duly completed
notice (the “Fundamental Change Purchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for
surrendering interests in Global Notes, if the Notes are not Physical Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date (the “Fundamental Change Expiration
Time”); and 
 (ii) deliver the Notes, in the case of Physical Notes, to the Paying Agent at any time
after delivery of the Fundamental Change Purchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance
with the procedures of the Depositary, in each case such delivery or transfer being a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor. 
 The Fundamental Change Purchase Notice in respect of any Notes to be purchased shall state: 
 (A) if such Notes are Physical Notes, the certificate numbers of such Notes to be delivered for purchase; 

  
 17 









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

(C) that such Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and the
Indenture; 
 provided, however, that if such Notes are Global Notes, the Fundamental Change Purchase Notice must also comply with
the applicable procedures of the Depositary. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the
Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of business on the Business Day
immediately preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.03. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof. 

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

(i) the events causing the Fundamental Change; 

(ii) the effective date of the Fundamental Change; 

  
 18 









  
 (iii)
the last date on which a Holder of Notes may exercise the purchase right pursuant to this Article 3; 
 (iv) the
Fundamental Change Purchase Price; 
 (v) the Fundamental Change Purchase Date; 

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

(vii) the Conversion Rate in effect on the date of the Fundamental Change Purchase Notice and, if applicable, any
adjustments to the Conversion Rate; 
 (viii) that the Notes with respect to which a Fundamental Change Purchase
Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with Section 3.03; and 

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the purchase rights of the Holders of Notes or
affect the validity of the proceedings for the purchase of the Notes pursuant to this Section 3.01. 
 (c) Notwithstanding
the foregoing, there shall be no purchase of any Notes pursuant to this Section 3.01 on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change
Purchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes). The Paying Agent shall promptly return to the respective Holders
thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes), and any
instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Purchase Notice with
respect to such Notes shall be deemed to have been withdrawn. 
 Section 3.02. Effect of Fundamental Change Purchase
Notice. Upon receipt by the Paying Agent of a Fundamental Change Purchase Notice specified in Section 3.01, the Holder of the Note in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change
Purchase Notice is withdrawn in accordance with Section 3.03) thereafter be 

  
 19 









 
entitled to receive the Fundamental Change Purchase Price in cash with respect to such Note. Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of funds by
the Paying Agent, on the later of (x) the Fundamental Change Purchase Date with respect to such Note (provided the conditions in Section 3.01 have been satisfied) and (y) the time of delivery or book-entry transfer of such Note to the
Paying Agent by the Holder thereof in the manner required by Section 3.01. 
 Section 3.03. Withdrawal of
Fundamental Change Purchase Notice. A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this
Section 3.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date, specifying: 
 (a) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, which must be an integral multiple of $1,000; 

(b) if such Notes are Physical Notes, the certificate numbers of the withdrawn Notes; and 

(c) the principal amount, if any, of such Notes that remains subject to the original Fundamental Change Purchase Notice; 

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

The Paying Agent will promptly return to the respective Holders thereof any Physical Notes with respect to which a Fundamental Change
Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.03. 
 Section 3.04. Deposit
of Fundamental Change Purchase Price. Prior to 11:00 a.m. (local time in The City of New York) on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either
of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the
Notes or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds cash sufficient to pay the Fundamental Change Purchase Price of the Notes for which a Fundamental Change Purchase Notice has
been tendered and not withdrawn in accordance with this Article 3 on the Fundamental Change Purchase Date, then as of such Fundamental Change Purchase Date, (a) such Notes shall cease to be outstanding and interest on such Notes shall cease to
accrue thereon (whether or not book-entry transfer of such Notes is made and whether or not such Notes are delivered to the Paying Agent) and (b) all other 

  
 20 









 
rights of the Holders with respect to such Notes shall terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery or book-entry transfer of such Notes).

 Section 3.05. Notes Purchased in Whole or in Part. Any Note that is to be purchased pursuant to this Article 3,
whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Notes, due endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge,
a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased. 

Section 3.06. Covenant to Comply With Applicable Laws Upon Purchase of Notes. In connection with any offer to purchase Notes
under Section 3.01, the Company shall, in each case if required, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required
schedule under the Exchange Act and (iii) otherwise comply with all federal and state securities laws, in each case, so as to permit the rights and obligations under Section 3.01 to be exercised in the time and in the manner specified in
Section 3.01. 
 Section 3.07. Repayment to the Company. To the extent that the aggregate amount of cash
deposited by the Company pursuant to Section 3.04 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, following the
Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company. 
 ARTICLE 4 

CONVERSION 
 Section 4.01. Right to Convert. Article 12 of the Original Indenture shall not apply to the Notes. Instead the conversion provisions set forth in this Article 4 shall, with respect to the
Notes, supersede in its entirety Article 12 of the Original Indenture, and all references in the Original Indenture to Article 12 thereof, and provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to
this Article 4 and the conversion provisions set forth in this Article 4, respectively. (a) Subject to and upon compliance with the provisions of this Article 4, each Holder of a Note shall have the right, at such Holder’s option, to
convert all or any portion (if the portion to be converted is an 

  
 21 









 
integral multiple of $1,000) of such Note (i) upon satisfaction of one or more of the conditions described in Section 4.01(b), at any time prior to the close of business on the Business
Day immediately preceding August 15, 2017 under the circumstances and during the periods set forth in Section 4.01(b), and (ii) regardless of whether any of the conditions described in Section 4.01(b) have been met, on or after
August 15, 2017 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at the Conversion Rate (subject to the settlement provisions of Section 4.02, the
“Conversion Obligation”). 
 (b) (i) Prior to the close of business on the Business Day
immediately preceding August 15, 2017, Holders may surrender their Notes for conversion during any calendar quarter commencing after December 31, 2010 (and only during such calendar quarter), if the Last Reported Sale Price of the Common
Stock for each of at least 20 Trading Days (whether or not consecutive) during the 30 consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the
applicable Conversion Price on each applicable Trading Day. The Conversion Agent, on behalf of the Company, shall determine at the beginning of each calendar quarter commencing after December 31, 2010 whether the Notes may be surrendered for
conversion in accordance with this subsection (b)(i) and shall notify the Company and the Trustee (in the case of a Conversion Agent other than the Trustee) on or prior to the fifth Business Day after the first day of such quarter of the Notes
becoming convertible in accordance with this subsection (b)(i). 
      (ii) Prior to
the close of business on the Business Day immediately preceding August 15, 2017, Holders may surrender their Notes for conversion during the five Business Day period after any five consecutive Trading Day period (the “Measurement
Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined by the Bid Solicitation Agent pursuant to this subsection (b)(ii) and the definition of Trading Price herein following a request by a Holder of Notes in
accordance with this subsection (b)(ii), for each Trading Day during that Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate on each such Trading Day (the
“Trading Price Condition”). The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company in accordance
with the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes in
accordance with this subsection (b)(ii) unless the Company has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is acting 

  
 22 









 
as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000
principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company)
to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day following the receipt of such evidence and on each successive
Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. If the Trading Price Condition set forth
above has been met, the Company shall so notify the Holders, the Conversion Agent (if other than the Trustee) and the Trustee within one Business Day. If, at any time after the Trading Price Condition set forth above has been met, the Trading Price
per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify the Holders, the Conversion Agent (if other
than the Trustee) and the Trustee within one Business Day. The Company shall initially act as the Bid Solicitation Agent. 
 (iii) If, prior to the close of business on the Business Day immediately preceding August 15, 2017, the Company elects to: 

(A) issue to all or substantially all holders of the Common Stock rights, options or warrants entitling them, for a period
of not more than 45 calendar days after the announcement date of such issuance to subscribe for or purchase shares of the Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding such announcement date; or 
 (B) distribute to all or substantially all holders of the Common Stock the Company’s assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value,
as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement for such distribution,

 then, in either case,
the Company shall notify the Holders of the Notes at least 20 Scheduled Trading Days before the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender their Notes for conversion at any time
until the earlier of (1) the close of business on the Business Day immediately preceding such Ex-Dividend Date and (2) the time the Company announces that such issuance or distribution will not take place. 

Holders of the Notes may not exercise the conversion right set forth under in this Section 4.01(b)(iii) if each Holder will have the
right to participate (as a result of holding the Notes, and at the same time and on the same terms as holders of the Common Stock participate) in any of the transactions described in this Section 4.01(b)(iii) as if such Holder held a number of
shares of the Common Stock equal to (i) the applicable Conversion Rate, multiplied by (ii) (x) the principal amount of the Notes held by such Holder divided by (y) $1,000, without having to convert its Notes. 

(iv) If, prior to the close of business on the Business Day immediately preceding August 15, 2017, (x) a
transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs, regardless of whether any Holder has the right to require the Company to purchase the Notes pursuant to Article 3, or (y) if the Company is a
party to a consolidation, merger, binding share exchange, or a sale, transfer, lease or other conveyance of all or substantially all of its assets, pursuant to which the Common Stock would be converted into or exchanged for, or would constitute
solely the right to receive, cash, securities or other assets, then in either case the Notes may be surrendered for conversion at any time from or after the date that is 20 Scheduled Trading Days prior to the initial anticipated effective date of
the transaction (or, if the Company does not have knowledge of such transaction on or prior to such date, the Business Day after the Company is required to give notice of such transaction) until 35 Trading Days after the actual effective date of
such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Purchase Date. The Company shall notify Holders, the Conversion Agent (if other than the Trustee) and the Trustee (i) as
promptly as practicable following the date the Company publicly announces such transaction but in no event less than 20 Scheduled Trading Days prior to the initial anticipated effective date of such transaction or (ii) if the Company does not
have knowledge of such transaction at least 20 Scheduled Trading Days prior to the initial anticipated effective date of such transaction, within one Business Day of the date upon which the Company receives notice, or otherwise becomes aware, of
such transaction but in no event later than the actual effective date of such transaction.

 Section 4.02.
Conversion Procedures. (a) In order to exercise the conversion privilege with respect to a beneficial interest in a Global Note, the holder of such beneficial interest must comply with the procedures of the Depositary for converting a
beneficial interest in a global note, and, if required, pay funds equal to any interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 4.03(f) and any documentary, stamp or similar issue
or transfer taxes, if any, to the extent required by Section 4.08. 
 (b) In order to exercise the conversion privilege
with respect to any Physical Notes, the Holder of any such Notes to be converted, in whole or in part, shall: 

(i) complete, manually sign and deliver an irrevocable conversion notice in the form set forth in the Form of Notice of
Conversion or a facsimile thereof (the “Conversion Notice”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder
wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered; 
 (ii) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, 

(iii) if required, furnish appropriate endorsements and transfer documents, 

(iv) if required, pay any documentary, stamp or similar issue or transfer taxes as set forth in Section 4.08; and

 (v) if required, make any payment required under Section 4.03(f). 

If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be
computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 
 Each conversion shall be deemed to have been effected as to the Notes surrendered for conversion on the date on which the Holder complies with the procedures for conversion set forth above (the
“Conversion Date”) with respect to such Notes; provided, however, that the Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder
of record as of the close of business on the last Trading 

  
 25 









 
Day of the related Observation Period. Upon the Conversion Date for Notes surrendered for conversion, the Person who surrendered such Notes for conversion shall no longer be a Holder with respect
to such Notes. The Conversion Agent shall, as promptly as possible, and in any event within one Business Day of the receipt thereof, provide the Company with notice of any conversion by a Holder of the Notes. 

(c) All such Notes surrendered for conversion shall, unless the shares of Common Stock issuable on conversion are to be issued in the
same name as the registration of such Notes, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or its duly authorized attorney. 

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

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

(f) Notwithstanding the foregoing, a Note in respect of which a Holder has delivered a Fundamental Change Purchase Notice pursuant to
Section 3.01(b) may be converted only if such Fundamental Change Purchase Notice is withdrawn in accordance with Article 3 prior to the close of business on the Business Day immediately preceding the relevant Fundamental Change Purchase Date.

 Section 4.03. Settlement Upon Conversion.  

(a) Subject to Section 4.07(a), upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting
Holder, in respect of each $1,000 principal amount of Notes being converted, a “Settlement Amount” equal to the sum of the Daily Settlement Amounts for each of the 75 Trading Days during the relevant Observation Period for such
Note, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with subsection (g) of this Section 4.03. 
 (b) “Daily Settlement Amount,” for each of the 75 consecutive Trading Days during the applicable Observation Period, shall consist of: 

(1) cash in an amount equal to the lesser of (i) $13.3333 and (ii) the Daily Conversion Value on such Trading
Day; and 

  
 26 









  
 (2) if
the Daily Conversion Value on such Trading Day exceeds $13.3333, the Daily Net Settlement Amount. 
 (c) All conversions
occurring on or after the 80th Scheduled Trading Day immediately preceding the Maturity Date shall be settled using the same forms and amounts of consideration. Prior to the 80th Scheduled Trading Day immediately preceding the Maturity Date, the
Company shall use the same forms and amounts of consideration for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same forms and amounts of consideration with respect to conversions
with Conversion Dates that occur on different Trading Days. 
 (d) With respect to any conversion of Notes, subject to
subsection (c) of this Section 4.03, the Company may irrevocably elect to settle all or a portion of the remainder, if any, of its Conversion Obligation in excess of the aggregate principal portion of the Notes being converted in cash by
informing the Trustee, converting Holders, through the Trustee, and the Depositary of such election no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions
occurring on or after the 80th Scheduled Trading Day immediately preceding the Maturity Date, no later than the 80th Scheduled Trading Day immediately preceding the Maturity Date) and the Company shall indicate in such notice the percentage of the
remainder, if any, of the Company’s Conversion Obligation in excess of the aggregate principal portion of the Notes being converted that will be paid in cash (the “Cash Percentage”). 

(e) The Daily Settlement Amounts (if applicable), the Daily Net Settlement Amounts (if applicable) and the Daily Conversion Values (if
applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts, the Daily Net Settlement Amounts (if applicable) or the Daily Conversion
Values, as the case may be, and the amount of cash, if any, deliverable in lieu of any fractional share, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts, the Daily Net
Settlement Amounts (if applicable) or the Daily Conversion Values, as the case may be, and the amount of cash, if any, deliverable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall
have no responsibility for any such determination. 

  
 27 









  
 (f) Upon the
conversion of any Notes, the Holder of such Notes shall not be entitled to receive any separate cash payment or additional shares representing accrued and unpaid interest, if any, except to the extent specified below. The Company’s delivery to
a converting Holder of the full amount of cash and the full number of shares of Common Stock, if any, together with any cash payment for any fractional share of Common Stock, if applicable, into which such Holder’s Note is convertible, or the
Trustee’s payment and delivery of such amounts on the Company’s behalf, shall be deemed to satisfy in full the Company’s obligation to pay the principal amount of the Notes so converted and accrued and unpaid interest, if any, to, but
not including, the Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a
combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first out of any cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on any Regular
Record Date and prior to the open of business on the immediately following Interest Payment Date, Holders of such Notes at the close of business on such Regular Record Date shall receive the full amount of interest payable on such Notes on the
corresponding Interest Payment Date notwithstanding the conversion. Notes converted during such period of time must be accompanied by funds equal to the amount of interest on the Notes so converted; provided that no such payment need be made
(i) if the Notes are converted after the close of business on the Regular Record Date immediately preceding the Maturity Date and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date,
(ii) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date, or (iii) to the extent of any
overdue interest, if any overdue interest exists at the time of conversion with respect to the Notes to be converted. Section 2.03 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by
Section 2.01 and this Section 4.03(f). 
 (g) Subject to Section 4.07(a) and subsection (h) below, the
Company shall pay or deliver, as the case may be, the consideration due in respect of a conversion on the third Business Day immediately following the last Trading Day of the applicable Observation Period. The Company shall not issue or deliver any
fractional share of Common Stock upon conversion of the Notes and shall instead, on the third Business Day immediately following the last Trading Day of the applicable Observation Period, pay cash in lieu of any fractional share of Common Stock
issuable upon conversion based on the Daily VWAP on the last Trading Day of the applicable Observation Period. 
 (h) If the
Hedge Counterparty elects Early Net Share Settlement of a Capped Call Transaction, the Company shall notify the Trustee and the 

  
 28 









 
Depositary in writing at least three Business Days prior to each early delivery of shares of Common Stock by the Hedge Counterparty of (i) the number of shares of Common Stock that the Hedge
Counterparty will so deliver and (ii) the date that such delivery will occur. The Company shall deliver the same number of shares of Common Stock to the Trustee on the date that the Company is scheduled to receive the corresponding delivery
from the Hedge Counterparty. The Company’s delivery of such shares of Common Stock to the Trustee shall satisfy the Company’s Conversion Obligation with respect to such number of shares of Common Stock in respect of the relevant conversion
of Notes. If the number of shares of Common Stock so delivered exceeds the number of shares the Company is required to deliver to satisfy its Conversion Obligation in respect of such conversion, the Trustee shall return the excess number of shares
to the Company. Following any delivery to the Trustee of shares of Common Stock that the Company is required to deliver to satisfy its Conversion Obligation, the Company shall have no ownership interest in such shares. The Trustee shall hold such
shares for the benefit of the converting Holders and shall distribute such shares to the converting Holders on the third Business Day immediately following the last Trading Day of the applicable Observation Period, unless required by law or
regulation to deliver such shares to the Holders prior to such date. If, while the Trustee is holding shares of Common Stock for the benefit of converting Holders, the Trustee receives any solicitation for any vote or other action to be taken with
respect to such shares, the Trustee shall abstain from voting or taking such other action. 
 Section 4.04. Adjustment
of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustment to the Conversion Rate if each Holder of the Notes has the
right to participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this
Section 4.04, without having to convert such Holder’s Notes, as if such Holder held a number of shares of Common Stock equal to (i) the applicable Conversion Rate, multiplied by (ii) (x) the principal amount of Notes
held by such Holder divided by (y) $1,000. 
 (a) If the Company issues solely shares of its Common Stock as a
dividend or distribution on all or substantially all of the Company’s shares of Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 

 

													
		 	CR1	  	=	  	CR0	  	x	  	  OS1  	  	
	 	  	  	  	  	  OS0  	  	

 where, 

  
 29 









  

							
		 	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on
the effective date of such share split or share combination, as applicable;
				
		 	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or such effective date, as applicable;
				
		 	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to giving effect to such dividend, distribution, share split or share combination; and
				
		 	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.


Any adjustment made under this Section 4.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date
of such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 4.04(a) is
declared but not so paid or made, or any share split or combination of the type described in this Section 4.04(a) is announced but the outstanding shares of Common Stock are not so split or combined, then the Conversion Rate shall be
immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or not to split or combine the outstanding shares of Common Stock, as the case may be, to the Conversion Rate that would
then be in effect if such dividend or distribution, share split or share combination had not been declared or announced. 
 (b)
If the Company issues to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase
shares of the Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of
announcement of such issuance, the Conversion Rate shall be increased based on the following formula: 
  

													
		 	 CR1	 	    =    	 	CR0	 	    x    	 	 OS0+ X 	  	
	 	 	 	 	 	 OS0+Y 	  	

 where, 

  
 30 









  

							
		 	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such issuance;
				
		 	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
				
		 	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
				
		 	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
				
		 	Y	  	=	  	the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock during the 10
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.


Any increase made under this Section 4.04(b) shall be made successively whenever any such rights, options or warrants are issued and
shall become effective immediately after the open of business on the Ex-Dividend Date of such issuance. No adjustment pursuant to the above formula shall result in a reduction of the Conversion Rate. However, 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 be the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or
warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in
effect if such Ex-Dividend Date for such issuance had not occurred. 
 For purposes of this Section 4.04(b) and
Section 4.01(b)(iii)(A), in determining whether any rights, options or warrants entitle the holders thereof to subscribe for or purchase shares of the Common Stock at less than the average of the Last Reported Sale Prices of the Common Stock
during the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate price payable to exercise such rights, options or warrants,
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, shall be determined in
good faith by the Board of Directors. 

  
 31 









  
 (c) If the Company
distributes shares of its Capital Stock, evidences of its indebtedness, or other assets or property of the Company or rights, options or warrants to acquire the Capital Stock or other securities of the Company, to all or substantially all holders of
the Common Stock, excluding: 
 (i) dividends, distributions, rights, options or warrants that require an
adjustment pursuant to Section 4.04(a) or Section 4.04(b); 
 (ii) dividends or distributions paid
exclusively in cash; and 
 (iii) Spin-Offs that require an adjustment pursuant to the provisions set forth below
in this Section 4.04(c); 
 (any of such shares of Capital Stock, evidences of indebtedness, or other assets or property or
rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 

 

											
	 CR1
	  	=	 	    
CR0	 	    x    	 	SP0
	 	
	  	 	 	 	SP0 – FMV	 	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined in good faith by the Board of Directors), as of the Ex-Dividend Date for such distribution, of the Distributed Property distributed with
respect to each outstanding share of the Common Stock.

 If the Board of Directors determines the
“FMV” (as defined above) of any distribution for purposes of this Section 4.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the 10
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution, if practicable. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater
than “SP0” (as defined above), then, in lieu of the


  
 32 









 
foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock, the amount
and kind of the Distributed Property that such Holder would have received if such Holder owned on the relevant record date a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.

 Any increase made under the portion of this Section 4.04(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. No adjustment pursuant to the above formula shall result in a reduction of the Conversion Rate. However, if such distribution is not so paid or made, the Conversion Rate shall be decreased to
be the Conversion Rate that would then be in effect if such distribution had not been declared. 
 With respect to an adjustment
pursuant to this Section 4.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares or other units of Common Equity of any class or series, or similar equity interest, of or relating to a Subsidiary
or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

  

											
	 CR1
	  	=	 	    
CR0	 	    x    	 	FMV0+MP0	 	
	  	 	 	 	MP0	 	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;
			
	FMV0	  	=	  	the product of (1) the average of the Last Reported Sale Prices of such Common Equity or similar equity interest (determined, for purposes of the definition of Last Reported Sale
Price, as if such Common Equity or similar equity interest were Common Stock) so paid or distributed for the 10 consecutive Trading Day period beginning on, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation
Period”); and (2) the number of shares of Common Stock or other units of Common Equity or similar equity interest so paid or distributed per share of Common Stock in such Spin-Off; and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.


  
 33 









  
 Any adjustment
pursuant to the preceding paragraph shall be determined on the last Trading Day of the Valuation Period but shall be given effect immediately after the open of business on the Ex-Dividend Date for the Spin-Off; provided that in respect of any
conversion for which the Conversion Date occurs during the Valuation Period, references in the portion of this Section 4.04(c) related to Spin-Offs to 10 consecutive Trading Days above shall be deemed, for purposes of determining the Conversion
Rate applicable to such conversion, to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, and including such Conversion Date. If the Ex-Dividend Date for the Spin-Off is
less than 10 consecutive Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references in the portion of this Section 4.04(c) related to Spin-Offs to 10 consecutive Trading Days shall be deemed
replaced, for purposes of calculating the affected Daily Conversion Rates in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the last
Trading Day of such Observation Period. 
 For the purposes of this Section 4.04(c) (and subject in all respects to
Section 4.12), 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 (either initially or under certain circumstances),
which rights, options or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also
issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate under this Section 4.04(c) will be required) until the
occurrence of the earliest Trigger Event, whereupon such rights, 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 4.04(c). If
any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Supplemental 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 of such deemed distribution (in
which case the original rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights, options or warrants, or
any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for 

  
 34 









 
which an adjustment to the Conversion Rate under this Section 4.04(c) was made, (1) in the case of any such rights, options or warrants which shall all have been redeemed or purchased
without exercise by any Holders thereof, upon such final redemption or repurchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be
readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by holders of Common Stock with respect to
such rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or
warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 

For purposes of this Section 4.04(c) and subsections (a) and (b) of this Section 4.04, if any dividend or
distribution to which this Section 4.04(c) applies also includes one or both of: 
 (A) a dividend or
distribution of shares of Common Stock to which Section 4.04(a) applies (the “Clause A Distribution”); 
 (B) a dividend or distribution of rights, options or warrants to which Section 4.04(b) applies (the “Clause B Distribution”), 

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or
distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 4.04(c) with respect thereto shall then be made, and (2) the Clause A
Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.04(a) and Section 4.04(b) with respect thereto shall then be made, except that,
if determined by the Company, (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included
in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to giving effect to such dividend, distribution, share split or share combination” within the meaning of Section 4.04(a) or
“outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 4.04(b). 

  
 35 









  
 (d) If the Company
makes or pays any cash dividend or distribution to all or substantially all holders of the Common Stock other than pursuant to a transaction that requires an adjustment to the Conversion Rate pursuant to the provisions described in
Section 4.04(e), and other than a regular, quarterly cash dividend that does not exceed $0.0025 per share (the “Initial Dividend Threshold”), the Conversion Rate shall be increased based on the following formula: 

 

											
	 CR1
	 	    =    	 	    
CR0	 	    x    	 	SP0
 –T	 	
	 	 	 	 	SP0 – C	 	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
			
	T	  	=	  	the Initial Dividend Threshold; provided that if the dividend or distribution in question is not a regular quarterly cash dividend, the Initial Dividend Threshold shall be
deemed to be zero; and
			
	C	  	=	  	the amount in cash per share that the Company distributes to holders of the Common Stock.

 The Initial Dividend Threshold shall be concurrently adjusted in a manner inversely proportional to adjustments to the Conversion Rate; provided that no adjustment shall be made to the Initial
Dividend Threshold for any adjustment to the Conversion Rate on account of a regular quarterly cash dividend pursuant to this Section 4.04(d). 
 Any increase pursuant to this Section 4.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution
is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal
to or greater than “SP0” (as defined above), then
in lieu of the foregoing increase, each Holder of a Note shall

receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if
such Holder owned on the relevant record date a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such cash dividend or distribution. 

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

							
		  	CR1    =    CR0    x  	 	AC+(SP1 x OS1)	  	
	  	 	OS0 x
SP1	  	

 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the first Trading Day after the Expiration Date;
			
	 CR1
	  	=	  	the Conversion Rate in effect immediately after the open of business on the first Trading Day after the Expiration Date;
			
	 AC
	  	=	  	the aggregate value of all cash and any other consideration (as determined in good faith by the Board of Directors) paid or payable for shares purchased in such tender offer or
exchange offer;
			
	 OS0
	  	=	  	the number of shares of Common Stock outstanding immediately prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange
offer;
			
	 OS1
	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange
offer; and
			
	 SP1
	  	=	  	the Last Reported Sale Price of the Common Stock on the first Trading Day after the Expiration Date.


The adjustment to the Conversion Rate under this Section 4.04(e) shall be determined immediately after the close of business on the
first Trading Day after the Expiration Date, but shall be given effect immediately after the open of business on the first Trading Day after the Expiration Date. 

  
 37 









  
 (f) Subject to any
applicable stock exchange listing requirements, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the best
interests of the Company. In addition, the Company may (but is not required to) increase the Conversion Rate, in addition to any adjustments pursuant to Section 4.04(a), 4.04(b), 4.04(c), 4.04(d), 4.04(e), 4.06 or the preceding sentence, to
avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event, subject to any applicable stock exchange
listing requirements. Whenever the Conversion Rate is increased pursuant to this Section 4.04(f), the Company shall mail to Holders of the Notes a notice of the increase at least 10 days prior to the date the increased Conversion Rate takes
effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 
 (g) All
calculations under this Article 4 shall be made by the Company and shall be made to the nearest cent (including, in the case of any adjustment to the Conversion Rate, the resulting adjustment to the Conversion Price) or to the nearest one
ten-thousandth of a share. No adjustment shall be required to be made for the Company’s issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or rights to purchase shares of Common
Stock or such convertible or exchangeable securities, other than as provided in this Section 4.04 and in Section 4.12. 
 (h) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth the Conversion Rate
after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have
knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such
adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder of the Notes. Failure to deliver
such notice shall not affect the legality or validity of any such adjustment. 
 (i) For purposes of this Section 4.04, the
number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the
Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

  
 38 









  
 (j) Notwithstanding
anything to the contrary in this Article 4, the Conversion Rate shall not be adjusted: 
 (i) upon the issuance
of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under
any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares
pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 
 (iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this
Section 4.04(j) and outstanding as of the date the Notes were first issued; 
 (iv) for a change solely in
the par value of the Common Stock; or 
 (v) for accrued and unpaid interest on the Notes, if any. 

Section 4.05. Adjustments of Prices. Whenever any provision of the Indenture requires the Company to calculate the Last
Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a period of multiple days (including an Observation Period, a Merger Valuation Period and the Stock Price for purposes of a Make-Whole
Fundamental Change), the Company shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the
event occurs, at any time during such period. 
 Section 4.06. Adjustment to Conversion Rate Upon Conversion Upon a
Make-Whole Fundamental Change.  
 (a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in
connection with such Make-Whole Fundamental Change, the Company shall, under certain circumstances, increase the Conversion Rate for such Notes by a number of additional shares of Common Stock (the “Additional Shares”), as described
below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the Conversion Date for such conversion occurs at any time from, and including,


  
 39 









 
the Effective Date of the Make-Whole Fundamental Change to, and including, the Business Day immediately prior to the related Fundamental Change Purchase Date (or, if the Make-Whole Fundamental
Change is not a Fundamental Change, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). 
 (b) Upon surrender of Notes for any conversion in connection with a Make-Whole Fundamental Change, the Company shall satisfy its Conversion Obligation in accordance with Section 4.02 in respect of
such converted Notes based on the Conversion Rate as increased to reflect the Additional Shares pursuant to the table below. 

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the
table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed paid) per share of the Common Stock in
the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share.
Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental
Change. 
 (d) The following table sets forth the number of Additional Shares to be added to the Conversion Rate per $1,000
principal amount of Notes for each Stock Price and Effective Date set forth below:

 The exact Stock
Prices and Effective Dates may not be set forth in the table above, in which case: 
 (i) If the Stock Price is
between two Stock Prices in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the
higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365- or 366-day year, as applicable. 

  
 40 









  
 (ii) If
the Stock Price is greater than $75.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (e) below), no Additional Shares shall be added to the
Conversion Rate. 
 (iii) If the Stock Price is less than $8.82 per share (subject to adjustment in the same
manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (e) below), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion exceed 113.3786 per $1,000 principal amount of Notes, subject to adjustment in the
same manner as the Conversion Rate as set forth in Section 4.04. 
 (e) The Stock Prices set forth in the column headings
of the table in Section 4.06(d) shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied
by a fraction, the numerator of which is the Conversion Rate immediately prior to the Conversion Rate adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional
Shares set forth in such table shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 4.04. 
 (f) The Company shall notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five business days after
such Effective Date. 
 Section 4.07. Effect of Recapitalization, Reclassification and Changes of the Common Stock. 

 (a) In the case of: 
 (i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination or a change solely in par value); 

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

(iii) any sale, transfer, lease or other conveyance of all or substantially all of the consolidated assets of the Company
to a third party; or 

  
 41 









  
 (iv)
any statutory share exchange; 
 in each case as a result of which the Common Stock would be converted into, or exchanged for, or would
constitute solely the right to receive, stock, other securities, or other property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at the effective time of such Merger Event, the right
to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination
thereof) that a holder of a number of shares of Common Stock equal to the Conversation Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”) upon such Merger Event and,
prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at
the date of execution of such supplemental indenture), providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event (i) the amount otherwise
payable in cash upon conversion of the Notes as set forth in Section 4.03 shall continue to be payable in cash, (ii) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case
may be, in respect of the remainder, if any, of the Company’s Conversion Obligation in excess of the aggregate principal portion of the Notes being converted, as set forth in Section 4.03(d), (iii) each share of Common Stock that
would otherwise have been required to be delivered upon a conversion of the Notes in accordance with Section 4.03 shall instead be deliverable in the amount and type of Reference Property that a holder of a share of Common Stock would have been
entitled to receive in such Merger Event (a “unit of Reference Property”) and (iv) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 

If the Merger Event causes the Common Stock to be converted into, or exchanged for, or constitute solely the right to receive more than a
single type of consideration (determined based in part upon any form of stockholder election), then (x) the Reference Property into which the Notes will be convertible or used to calculate the Daily VWAP, as the case may be, shall be deemed to
be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (y) the unit of Reference Property for purposes of the immediately preceding paragraph shall
refer to the consideration referred to in clause (x) attributable to one share of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable
after such determination is made. 

  
 42 









  
 The Company shall not
become a party to any such Merger Event unless its terms are consistent with this Section 4.07. Such supplemental indenture described in the second preceding paragraph shall provide for adjustments which shall be as nearly equivalent as is
possible to the adjustments provided for in this Article 4. If, in the case of any such Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person
other than the successor or purchasing Person, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person. 
 If Reference Property in any Merger Event consists solely of cash, then for all conversions that occur after the effective date of such Merger Event (1) the consideration due upon such conversion
shall consist of cash in an amount, per $1,000 principal amount of such Note, equal to the product of (A) the amount of cash paid per share of Common Stock pursuant to such Merger Event and (B) the applicable Conversion Rate on the
Conversion Date for such conversion; and (2) the Company shall pay such consideration on the third Business Day after such Conversion Date. 
 (b) The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Notes maintained by the
Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 4.07 shall similarly apply to successive Merger
Events. 
 (c) In connection with any Merger Event, the Initial Dividend Threshold shall be subject to adjustment as described
in clause (A), clause (B) or clause (C) below, as the case may be. 
 (i) In the case of a Merger Event
in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed entirely of shares of common stock (the “Merger Common Stock”), the
Initial Dividend Threshold at and after the effective time of such Merger Event shall be equal to (x) the Initial Dividend Threshold immediately prior to the effective time of such Merger Event, divided by (y) the number of shares of
Merger Common Stock that a holder of one share of Common Stock would receive in such Merger Event (such quotient rounded down to nearest cent). 
 (ii) In the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed in
part of shares of Merger Common Stock, the Initial Dividend Threshold at and after the 

  
 43 









 
effective time of such Merger Event shall be equal to (x) the Initial Dividend Threshold immediately prior to the effective time of such Merger Event, multiplied by (y) the Merger
Valuation Percentage for such Merger Event (such quotient rounded down to nearest cent). 
 (iii) For the
avoidance of doubt, in the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed entirely of consideration other
than shares of common stock, the Initial Dividend Threshold at and after the effective time of such Merger Event shall be equal to zero. 
 Section 4.08. Taxes on Shares Issued. If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue or delivery of
shares of Common Stock upon such conversion; provided, however, that if such tax is due because the Holder has requested that shares of Common Stock be issued in a name other than such Holder’s name, then such taxes shall be paid by such
Holder, and the Company shall not be required to issue or deliver any stock certificate evidencing such shares unless and until such Holder shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid. 
 Section 4.09. Reservation of Shares; Shares to be Fully Paid; Compliance With
Governmental Requirements; Listing of Common Stock. The Company shall reserve, out of its authorized but unissued shares or shares held in treasury, all of the shares of Common Stock required to satisfy conversion of the Notes from time to time
as such Notes are presented for conversion (initially 38,505,960 shares). 
 The Company covenants that all shares of Common
Stock that may be issued upon conversion of Notes shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge
(other than those created by the Holder). 
 Upon conversion of Notes, if the Common Stock is then listed or quoted on any
national securities exchange or over-the-counter or other domestic market, the Company shall list or cause to have quoted on such exchange or other market any shares of Common Stock to be issued upon conversion. 

Section 4.10. Appointment of Conversion Agent; Responsibility of Conversion Agent and Trustee. The Company hereby appoints
the Trustee to act as the initial Conversion Agent with respect to the Notes. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility 

  
 44 









 
to any Holder of Notes to determine or calculate the Conversion Rate, to determine whether any facts exist which may require any adjustment of the Conversion Rate, or to confirm the accuracy of
any such adjustment when made or the appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to
the validity or value (or the kind or amount) of any shares of Common Stock or of any other securities or property that may at any time be issued or delivered upon the conversion of any Notes; and the Trustee and any other Conversion Agent make no
representations with respect thereto. Neither the Trustee nor any other Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or
property or cash upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 4. The rights, privileges, protections, immunities and
benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacity as Conversion
Agent and if it is so appointed by the Company and accepts such appointment, as Bid Solicitation Agent. 
 Section 4.11.
Notice to Holders Prior to Certain Actions. In the case of any: 
 (a) action by the Company or one of its Subsidiaries that
would require an adjustment in the Conversion Rate pursuant to Section 4.04 or Section 4.12; or 
 (b) Merger Event;
or 
 (c) voluntary or involuntary dissolution, liquidation or winding up of the Company or any of its Subsidiaries; 

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Supplemental Indenture), the Company shall
cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder of Notes at such Holder’s address appearing on in the Note Register, which the Company shall provide to the Trustee, as
promptly as practicable but in any event at least 10 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such action by the Company or one of its
Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (y) the date on which such Merger
Event, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to 

  
 45 









 
exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall
not affect the legality or validity of such dividend (or any other distribution), Merger Event, dissolution, liquidation or winding up. 
 Section 4.12. Stockholder Rights Plan. If the Company has a rights plan in effect upon a conversion of any Note and the Company delivers any shares of Common Stock upon such conversion, the
converting Holder shall receive, in addition to such shares of Common Stock, the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as
may be provided by the terms of any stockholder rights plan adopted by the Company and in effect upon conversion of such Notes, as the same may be amended from time to time. Notwithstanding the foregoing, if prior to such conversion the rights have
separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights agreement, the Conversion Rate shall be increased at the time of separation as if the Company had distributed, shares of the
Company’s Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants to all or substantially all holders of Common Stock as described in Section 4.04(c), subject to decrease in accordance with
Section 4.04(c) in the event those rights expire, terminate or are redeemed. 
 ARTICLE 5 

EVENTS OF DEFAULT 
 Section 5.01. Events of Default. Article 6 of the Original Indenture shall not apply to the Notes. Instead the events of default provisions set forth in this Article 5 shall, with respect to
the Notes, supersede in their entirety Article 6 of the Original Indenture, and all references in the Original Indenture to Article 6 thereof and events of default provisions therein, as the case may be, shall, with respect to the Notes, be deemed
to be references to this Article 5 and events of default provisions set forth in this Article 5, respectively. Each of the following events is an “Event of Default” with respect to the Notes: 

(a) default in the payment of principal of any Note when due and payable on the Maturity Date, upon required purchase in connection with
a Fundamental Change, or otherwise; 
 (b) failure by the Company to pay an installment of interest on any Note when due, if
such failure continues for 30 days after the date when due; 
 (c) upon exercise of a Holder’s conversion right in
accordance with Article 4, failure by the Company to deliver, or cause the Trustee to deliver, to such Holder the full amount of conversion consideration deliverable in respect of the Notes surrendered for conversion when due, in accordance with the
Indenture; 

  
 46 









  
 (d) failure by the
Company to provide a Fundamental Change Company Notice pursuant to Section 3.01(b) or notice of a specified corporate event required by Section 4.01(b)(iii) or Section 4.01(b)(iv) in accordance with the relevant Section, in each case
when due if the failure continues for five calendar days after the date when due; 
 (e) failure by the Company to comply with
its obligations under Section 8.01(a) and (b) and Section 8.02; 
 (f) failure by the Company to comply with any
other term, covenant or agreement contained in the Notes or the Indenture, if such failure is not cured within 60 days after notice to the Company by the Trustee or to the Trustee and the Company by Holders of at least 25% in aggregate principal
amount of the Notes then outstanding, in accordance with the Indenture; 
 (g) default (i) in any scheduled payment of
principal of any Indebtedness of the Company or any of its Subsidiaries (other than the Notes and other than non-recourse Indebtedness), aggregating more than $25,000,000 in principal amount, when due and payable after giving effect to any
applicable grace period or (ii) in the performance of any other term or provision of any Indebtedness of the Company or any of its Subsidiaries (other than the Notes and other than non-recourse Indebtedness) in excess of $25,000,000 principal
amount that results in such Indebtedness becoming or being declared due and payable before the date on which it would otherwise become due and payable, and such acceleration is not rescinded or annulled, or such Indebtedness is not discharged,
within a period of 5 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes, a written notice
specifying such default(s) and stating that such notice is a “Notice of Default” under the Indenture. 
 (h) one or
more final, non-appealable judgments against the Company or any of its Subsidiaries, the aggregate uninsured portion of which is at least $25.0 million, if such judgments are not paid or discharged within 120 days; 

(i) the Company or any Subsidiary thereof that is a “Significant Subsidiary” (as defined in Regulation S-X under the Exchange
Act) or any group of Subsidiaries of the Company that in the aggregate would constitute a Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or
any such Significant Subsidiary or such group of Subsidiaries or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or 

  
 47 









 
seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or such group of Subsidiaries or any substantial
part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of
creditors, or admits, in writing, its inability to pay its debts as they become due; or 
 (j) an involuntary case or other
proceeding shall be commenced against the Company or any such Significant Subsidiary or such group of Subsidiaries seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or such group of
Subsidiaries or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant
Subsidiary or such group of Subsidiaries or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 90 consecutive days. 

Section 5.02. Acceleration; Rescission and Annulment. In case one or more Events of Default shall have occurred and be
continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 5.01(i) or Section 5.01(j) with respect to the Company, but including an Event of Default specified in
Section 5.01(i) or Section 5.01(j) with respect to any of the Company’s Significant Subsidiaries, or a group of its Subsidiaries that in aggregate would constitute a Significant Subsidiary), unless the principal of all of the Notes
shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 2.11 of the Original Indenture, by notice in writing
to the Company (and to the Trustee if given by Holders), may, and the Trustee at the request of Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 2.11 of the Original
Indenture shall, declare 100% of the principal of, and any accrued and unpaid interest on, all of the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and
payable, notwithstanding any provision in the Indenture or in the Notes to the contrary. In the case of an Event of Default specified in Section 5.01(i) or Section 5.01(j) with respect to the Company (and not solely with respect to any of
its Significant Subsidiaries, or a group of its Subsidiaries that in aggregate would constitute a Significant Subsidiary), the principal of, and accrued and unpaid interest, if any, on, all Notes shall automatically become immediately due and
payable. 

  
 48 









  
 The immediately
preceding paragraph, however, is subject to the conditions that if, at any time after the principal of and interest on the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall
have been obtained or entered as hereinafter provided, (1) the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that
shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal, at the rate borne by
the Notes plus one percent at such time) and amounts due to the Trustee pursuant to Section 7.07 of the Original Indenture, and (2) rescission would not conflict with any order or decree of a court of competent jurisdiction and
(3) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or
waived pursuant to Section 5.09, then and in every such case the Holders of a majority in aggregate principal amount of the Notes then outstanding may, by written notice to the Company and to the Trustee, rescind and annul any consequence of
any such Default or Event of Default, including, without limitation, acceleration of the obligations, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture; but no such rescission and
annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. 
 Section 5.03. Additional Interest. Notwithstanding any provisions of the Original Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating to
(i) its 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) its
failure to comply with its reporting obligations set forth in Section 2.03, shall for the 180 days after the occurrence of such an Event of Default consist exclusively of the right to receive additional interest on the Notes at a rate equal to
0.25% per annum of the principal amount of the Notes outstanding (“Additional Interest”) for each day during the 90-day period beginning on, and including, the occurrence of such an Event of Default during which such Event of
Default is continuing, which Additional Interest rate shall be increased by an additional 0.25% per annum, on the 91st day after the occurrence of such Event of Default (if such Event of Default is not cured or waived prior to such 91st day);
provided that the rate at which such Additional Interest accrues may in no event exceed 0.50% per annum. If the Company elects to pay Additional Interest on account of such an Event of Default, such Additional Interest shall be payable
in the same manner and on the same dates as the stated interest payable on the Notes. On the 181st day after such Event of Default occurs (if such Event of Default is not cured or waived on or prior to such 181st day), the Notes shall be subject to


  
 49 









 
acceleration as provided in Section 5.02. This Section 5.03 shall not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. In the event
the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 5.03, the Notes shall be subject to acceleration as provided in Section 5.02. 

In order to elect to pay Additional Interest as the sole remedy during the first 180 days after the occurrence of an Event of Default
described in the immediately preceding paragraph, the Company must give notice to Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the Company’s failure to timely give
all Holders, the Trustee and the Paying Agent such notice, the Notes shall be immediately subject to acceleration as provided in Section 5.02. 
 Section 5.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 5.01 shall have occurred, the Company shall, upon
demand of the Trustee, pay to it, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal (including the Fundamental Change Purchase
Price, if applicable) and interest, if any, at the rate borne by the Notes plus one percent at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.07 of the
Original Indenture. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the
Company or any other obligor upon the Notes, wherever situated. 
 In the event there shall be pending proceedings for the
bankruptcy or for the reorganization of the Company or any other obligor on the Notes under title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or
such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 5.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims
for the whole amount of principal and accrued and unpaid interest, if any, in respect of the 

  
 50 









 
Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have
the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other
obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee
under Section 7.07 of the Original Indenture; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as
administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including
reasonable agents and counsel fees, and including any other amounts due to the Trustee under Section 7.07 of the Original Indenture, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation,
expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and
other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 

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

All rights of action and of asserting claims under this Supplemental Indenture, or under any of the Notes, may be enforced by the Trustee
without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of the Indenture to which
the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

  
 51 









  
 In case the Trustee
shall have proceeded to enforce any right under this Supplemental Indenture and such proceedings shall have been discontinued or abandoned because of any waiver or rescission and annulment or for any other reason or shall have been determined
adversely to the Trustee, then and in every such case the Company, the Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the Holders, and the Trustee shall continue as though no such proceeding had been instituted. 
 Section 5.05. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 5 with respect to the Notes shall be applied in the order following, at
the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 

First, to the payment of all amounts due the Trustee under Section 7.07 of the Original Indenture; 

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any
cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon
such overdue payments at the rate borne by the Notes at such time plus one percent, such payments to be made ratably to the Persons entitled thereto; 
 Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of the
Fundamental Change Purchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has been collected by the
Trustee, upon overdue installments of interest at the rate borne by the Notes at such time plus one percent, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment
of such principal (including, if applicable, the Fundamental Change Purchase Price and the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of
interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Purchase Price and any cash due upon conversion) and accrued and unpaid
interest; and 

  
 52 









  
 Fourth, to the payment
of the remainder, if any, to the Company. 
 Section 5.06. Proceedings by Holders. Except to enforce the right to
receive payment of principal (including, if applicable, the Fundamental Change Purchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, the Holder of a Note shall have the right to
institute a suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, if (and
only if): 
 (a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the
continuance thereof, as herein provided; 
 (b) Holders of at least 25% in aggregate principal amount of the Notes then
outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 
 (c) such Holder or Holders shall have offered, and, if requested, provided, to the Trustee such indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or
thereby; and 
 (d) the Trustee shall have neglected or refused to institute any such action, suit or proceeding for 60 days
after its receipt of such notice, request and offer of indemnity and does not receive, during those 60 days, from Holders of a majority in aggregate principal amount of the Notes then outstanding, a direction pursuant to Section 5.09 that is
inconsistent with the request, it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner
whatever by virtue of or by availing of any provision of this Supplemental Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce
any right under the Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 5.06, each and every
Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Notwithstanding any other
provision of the Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Purchase Price, if applicable) of, (y) accrued and
unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of any such
payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder. 

  
 53 









  
 Section 5.07.
Proceedings by Trustee. In case of an Event of Default the Trustee may in its discretion proceed to protect and enforce the rights vested in it by the Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any
of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in
the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law. 

Section 5.08. Remedies Cumulative and Continuing. All powers and remedies given by this Article 5 to the Trustee or to the
Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in the Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall
impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 5.06, every power and remedy given by this Article 5 or by law
to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders. 
 Section 5.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority in aggregate principal amount of the Notes then outstanding determined in
accordance with Section 2.11 of the Original Indenture shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with
respect to Notes; provided, however, that the Trustee may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the
Trustee in personal liability. The Holders of a majority of the aggregate principal amount of the Notes then outstanding determined in accordance with Section 2.11 of the Original Indenture may on behalf of the Holders of all of the Notes, by
written notice to the Trustee and the Company, waive any Default or Event of Default hereunder except that no such waiver shall be effective as to a Default or Event of Default (i) in the payment of the principal of, or accrued and unpaid
interest, if any, on the Notes or in the payment of the Fundamental Change Purchase Price, (ii) arising from a failure by the Company to pay or deliver, as the case may be, or to cause the Trustee to deliver, to converting Holders the
consideration due upon conversion of the Notes in accordance with the Indenture or (iii) in respect of a covenant or 

  
 54 









 
provision hereof that under Article 7 cannot be modified or amended without the consent of the Holder of each outstanding Note affected unless each affected Holder consents. Upon any such waiver
the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.
Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 5.09, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have been cured and to be not
continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 Section 5.10. Notice of Defaults. The Trustee shall, within 90 days after the occurrence of a Default of which a Responsible Officer has actual knowledge, if such Default is continuing, mail
to all Holders as the names and addresses of such Holders appear upon the Note Register, notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided
that, except in the case of a Default in the payment of the principal (including the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery, as the case may
be, of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in
good faith determines that the withholding of such notice is in the interests of the Holders. Section 7.05 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 5.10. 

Section 5.11. Statements as to Defaults. The Company shall deliver to the Trustee, as soon as possible, and in any event
within 30 days after the occurrence of any Event of Default or Default, an Officers’ Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or proposes to take in respect
thereof. 
 Section 5.12. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and
deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of the Indenture. 
 Section 5.13. Undertaking to Pay Costs. All parties to this Supplemental Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court
may, in its discretion, require, in any suit for the enforcement of any right or remedy under the Indenture or the Notes, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such 

  
 55 









 
suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 5.13 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted
by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 2.11 of the Original Indenture, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change Purchase Price with respect to the Notes being purchased as provided in Article 3) on
or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 4. 
 ARTICLE 6 
 SATISFACTION AND DISCHARGE

 Section 6.01. Satisfaction and Discharge of the Supplemental Indenture. Articles 8 and 9 of the Original
Indenture shall not apply to the Notes. Instead, the satisfaction and discharge provisions set forth in this Article 6 shall, with respect to the Notes, supersede in their entirety Articles 8 and 9 of the Original Indenture and all references in the
Original Indenture to Articles 8 and 9 thereof and satisfaction and discharge provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 6 and the satisfaction and discharge provisions set
forth in this Article 6. This Supplemental Indenture shall upon request of the Company contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Supplemental Indenture, when (a) (i) all Notes theretofore authenticated and delivered have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the
Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether at the Maturity Date, on any Fundamental Change Purchase Date, upon conversion or otherwise, cash and/or (in the case of conversion) shares of
Common Stock sufficient to pay all of the outstanding Notes or satisfy the Company’s Conversion Obligation, as the case may be, and pay all other sums due and payable under this Supplemental Indenture by the Company; and (b) the Company
has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Supplemental Indenture have been complied with.
For the avoidance of doubt, notwithstanding the satisfaction and discharge of this Supplemental Indenture, the obligations of the Company to the Trustee under Section 7.07 of the Original Indenture shall survive. 

  
 56 









  
 Section 6.02.
Deposited Monies to be Held in Trust by Trustee. Subject to Section 6.04, all monies and shares of Common Stock, if any, deposited with the Trustee pursuant to Section 4.03(h) or Section 6.01 shall be held in trust for the sole
benefit of the Holders of the Notes, and such monies and shares of Common Stock shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of
the particular Notes for the payment, settlement or redemption of which such monies or shares of Common Stock have been deposited with the Trustee, of all sums or amounts due and to become due thereon for principal and interest, if any. 

Section 6.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Supplemental Indenture, all
monies and shares of Common Stock, if any, then held by any Paying Agent (if other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all
further liability with respect to such monies and shares of Common Stock. 
 Section 6.04. Return of Unclaimed Monies.
Subject to the requirements of applicable law, any monies and shares of Common Stock deposited with or paid to the Trustee for payment on the Notes and not applied but remaining unclaimed by the Holders of the Notes for one year after the date
upon which the payment on such Notes shall have become due and payable, shall be repaid to the Company by the Trustee on demand, and all liability of the Trustee shall thereupon cease with respect to such monies and shares of Common Stock; and the
Holder of any of the Notes shall thereafter look only to the Company for any payment or delivery that such Holder of the Notes may be entitled to collect unless an applicable abandoned property law designates another Person. 

Section 6.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or shares of Common Stock in
accordance with Section 6.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 6.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in accordance with Section 6.02; provided,
however, that if the Company makes any payment of interest on, principal of or payment or delivery in respect of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money or shares of Common Stock, if any, held by the Trustee or Paying Agent.

 ARTICLE 7 

SUPPLEMENTAL INDENTURES 
 Section 7.01. Supplemental Indentures Without Consent of Holders. Article 10 of the Original Indenture shall not apply to the Notes. Instead the provisions set forth in this Article 7 shall,
with respect to the Notes, supersede in their entirety Article 10 of the Original Indenture, and all references in the Original Indenture to Article 10 thereof and provisions therein, as the case may be, shall, with respect to the Notes, be deemed

Section 7.02. Supplemental Indentures with Consent of Holders. The Company and the Trustee may only amend or supplement this
Supplemental Indenture or the Notes with the written consent of the Trustee and the Holders of at least a majority in aggregate principal amount of the Notes then outstanding. Notwithstanding the foregoing, no amendment or supplemental indenture may
without the written consent of the Holder of each Note affected:

 ARTICLE 8 
 SUCCESSOR COMPANY 
 Section 8.01.
Consolidation, Merger and Sale of Assets. Article 5 of the Original Indenture shall not apply to the Notes. The provisions set forth in this Article 8 shall, with respect to the Notes, supersede in their entirety Article 5 of the Original
Indenture, and all references in the Original Indenture to Article 5 thereof shall, with respect to the Notes, be deemed to be references to this Article 8. The Company shall not consolidate with or merge with or into, or sell, transfer, lease or
otherwise convey all or substantially all of its consolidated assets to, another Person, unless: 
 (a) the resulting, surviving
or transferee Person (if not the Company) (the “Successor Company”) is a corporation organized and existing under the laws of the United States, any State thereof or the District of Columbia and such Successor Company (if not the
Company) expressly assumes by supplemental indenture all of the Company’s obligations under the Notes and the Indenture; 

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and is continuing under the
Indenture; and 
 (c) the Company shall have delivered to the Trustee the Officers’ Certificate and Opinion of Counsel
pursuant to Section 8.03. 
 For purposes of this Section 8.01, the sale, conveyance, transfer or lease of all or
substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person that is not a Subsidiary of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute
all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person.

 Section 8.02. Successor Person Substituted. In the case of any such consolidation, merger, sale, transfer, lease
or other conveyance in which the Company is not the Successor Company and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee, of the due and punctual payment of the principal of and
interest on all of the Notes, and the due and punctual performance and observance of all of the covenants and conditions of the Indenture to be performed or satisfied by the 

  
 60 









 
Company, such Successor Company shall succeed to, and be substituted for, and may exercise every right and power of, the Company, with the same effect as if it had been named herein as the party
of the first part, and the Company shall be discharged from its obligations under the Notes and the Indenture, except in the case of a lease of all or substantially all of the Company’s properties and assets. Such Successor Company thereupon
may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder that theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of
such Successor Company instead of the Company and subject to all the terms, conditions and limitations in the Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that
previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the
Notes so issued shall in all respects have the same legal rank and benefit under the Indenture as the Notes theretofore or thereafter issued in accordance with the terms of the Indenture as though all of such Notes had been issued at the date of the
execution hereof. In the event of any such consolidation, merger, sale, transfer or conveyance (but not in the case of a lease) upon compliance with this Article 8 the Person named as the “Company” in the first paragraph of the Indenture
or any successor that shall thereafter have become such in the manner prescribed in this Article 8 may be dissolved, wound up and liquidated at any time thereafter and such Person shall be discharged from its liabilities as obligor and maker of the
Notes and from its obligations under the Indenture. 
 In case of any such consolidation, merger, sale, conveyance, transfer or
lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 8.03. Opinion of Counsel to be Given to Trustee. Prior to execution of any supplemental indenture pursuant to this Article 8, the Trustee shall receive an Officers’ Certificate
and an Opinion of Counsel in accordance with Section 13.05 of the Original Indenture as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption complies with the provisions of this
Article 8. 
 ARTICLE 9 
 LISTS OF HOLDERS 
 Section 9.01. Lists of Holders. Section 2.08
of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Article 9. The Company covenants and agrees that it will furnish or cause to be furnished to the Trustee, semi-annually, not more than 15 days
after each May 1 and 

  
 61 









 
November 1 in each year beginning with May 1, 2011, and at such other times as the Trustee may request in writing, within 30 days after receipt by the Company of any such request (or
such lesser time as the Trustee may reasonably request in order to enable it to timely provide any notice to be provided by it hereunder), a list in such form as the Trustee may reasonably require of the names and addresses of the Holders as of a
date not more than 15 days (or such other date as the Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no such list need be furnished so long as the Trustee is
acting as Registrar. In addition, the Trustee and the Company shall comply with TIA § 312. 
 Section 9.02.
Preservation and Disclosure of Lists. The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders contained in the most recent list furnished to it as provided in
Section 9.01 or maintained by the Trustee in its capacity as Registrar, if so acting. The Trustee may destroy any list furnished to it as provided in Section 9.01 upon receipt of a new list so furnished.

 [FORM OF REVERSE OF
NOTE] 
 RADIAN GROUP INC. 
 3.00% Convertible Senior Note due 2017 
 This Note is one of a duly authorized
issue of Securities of the Company designated as its 3.00% Convertible Senior Notes due 2017 (herein called the “Notes”), issued under a Senior Indenture dated as of November 15, 2010 (the “Original
Indenture”), as supplemented by the First Supplemental Indenture dated as of November 15, 2010 (herein called the “Supplemental Indenture”; the Original Indenture, as supplemented by the Supplemental Indenture, and as
it may be further amended from time to time, the “Indenture”), by and between the Company and U.S. Bank National Association, herein called the “Trustee”, and reference is hereby made to the Indenture for a
statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. Additional
Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. 

This Note is not subject to redemption at the option of the Company prior to November 15, 2017 and, for the avoidance of doubt, this
Note is not subject to the provisions of Article 3 of the Original Indenture. 
 The provisions in Articles 5, 6, 8, 9, 10 and
12, and Sections 2.03, 2.08, 2.09(d), (e), (k) and (n), 2.13, 4.03 and 7.05 of the Original Indenture shall not apply to the Notes, and Article 4, Article 5, Article 6, Article 7, Article 8, Article 9, Section 2.01, Section 2.02(b),
Section 2.02(d), Section 2.03, Section 2.04, Section 2.05, Section 4.03(f), Section 5.10 and the definition of “outstanding” in Section 1.02 of the Supplemental Indenture supersede the entirety thereof.

 As provided in and subject to the provisions of the Supplemental Indenture, upon the occurrence of a Fundamental Change, the
Holder has the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Purchase Date at
a price equal to the Fundamental Change Purchase Price. 
 As provided in and subject to the provisions of the Supplemental
Indenture, the Holder hereof has the right, at its option (i) during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the Business Day immediately preceding
August 15, 2017, and (ii) on or after August 15, 2017, at any time prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert this Note or a portion thereof that is $1,000 or
an 

  
 A-6









 
integral multiple thereof, into cash up to the aggregate principal amount of the Notes to be converted and cash, shares of Common Stock or a combination thereof, at the Company’s election,
in respect of the remainder, if any, of the Company’s Conversion Obligation, at the applicable Conversion Rate specified in the Supplemental Indenture, as adjusted from time to time as provided in the Indenture. 

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

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal of, interest on and the consideration due upon conversion of, this Note at the time, place and rate, and in the coin and currency, herein prescribed.


  
 A-7









  
 As provided in the
Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Note Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the
principal of and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or its attorney duly authorized in
writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Notes are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided
in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes and of like tenor of a different authorized denomination, as requested by the Holder surrendering the
same. 
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge payable in connection therewith to the extent provided in the Indenture. 
 Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or Trustee may treat the Person in whose name the Note is registered as the owner
hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
