one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the

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
canceled. 
 Definitive Notes issued in exchange for all or a part of the Global Notes pursuant to this Section 2.06(d) shall be

 -16- 








 At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred,
such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with its standing procedures. At any time prior to such cancellation, if any interest in a Global Note is exchanged for definitive Notes, converted, canceled,
repurchased or transferred to a transferee who receives definitive Notes therefor or any definitive Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall be appropriately reduced or increased,
as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

 THE SALE OF THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, THIS SECURITY MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN
THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES (1) THAT IT WILL NOT WITHIN THE LATER OF (X) ONE YEAR AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE NOTES (INCLUDING THROUGH THE EXERCISE OF THE OPTION TO PURCHASE

IF THE COMPANY HAS NOT SATISFIED THE CURRENT PUBLIC INFORMATION REQUIREMENTS OF RULE 144, ONE YEAR) AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE NOTES
(INCLUDING THROUGH THE EXERCISE OF THE OPTION TO PURCHASE ADDITIONAL NOTES) UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED AND (Y) 90 DAYS AFTER IT CEASES TO BE AN AFFILIATE (WITHIN THE MEANING OF RULE 144 UNDER THE SECURITIES ACT) OF
THE COMPANY, FURNISH TO THE TRANSFER AGENT AND THE COMPANY SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REQUIRE AND MAY RELY UPON TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION
NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. IN ANY EVENT, NO AFFILIATE OF THE COMPANY MAY RESELL THIS SECURITY, UPON THE CONVERSION OF THE NOTE PURSUANT TO WHICH THIS SECURITY WAS ISSUED, OTHER THAN UNDER A REGISTRATION
STATEMENT THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT OR PURSUANT TO AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT IN A TRANSACTION THAT RESULTS IN SUCH SECURITY NO LONGER BEING “RESTRICTED SECURITIES” (AS
DEFINED UNDER RULE 144). 
 Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms
may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate
number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.06(e). 
 (f) Any Note or
Common Stock issued upon the conversion or exchange of a Note that is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an
exemption from the registration requirements of the Securities Act in a transaction that results in such Notes or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144). During the period of
one year after the last original issuance of the Notes, the Company shall not, and shall not permit any of its “affiliates” (as defined under Rule 144) to, resell any of the Notes that constitute “restricted securities” under
Rule 144 that have been reacquired by any of them. 
 (g) Notwithstanding any provision of this Section 2.06 to the contrary, in the
event Rule 144 as promulgated under the Securities Act (or any successor rule) is amended to change the one-year holding period thereunder (or the corresponding period under any successor rule), from and after receipt by the Trustee of the
Officers’ Certificate and Opinion of Counsel provided for in this Section 2.06(g), (i) each reference in Section 2.06(d) to “one year” and in the restrictive legend set forth in such paragraph to “ONE YEAR”
shall be deemed for all purposes hereof to be references to such changed period, (ii) each reference in Section 2.06(e) to “one year” and in the restrictive legend set forth in such paragraph to “ONE YEAR” shall be
deemed for all purposes hereof to be references to such changed period and (iii) all corresponding references in the Notes (including the definition of Resale Restriction Termination Date) and the restrictive legends thereon shall be deemed for
all purposes hereof to be references to such changed period, provided that such changes shall not become effective if they are otherwise prohibited by, or would otherwise cause a violation of, the then-applicable federal securities laws. The
provisions of this Section 2.06(g) will not be effective until such time as the Opinion of Counsel and Officers’ Certificate have been received by the Trustee hereunder. This Section 2.06(g) shall apply to successive amendments to
Rule 144 (or any successor rule) changing the holding period thereunder.

 Section 2.07. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the
Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case
of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such
security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the holder of a sum sufficient to cover any
tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been tendered for repurchase upon a Fundamental Change or
is about to be converted into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a
substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish
to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such
substitution, including without limitation if a Note is replaced and subsequently presented or claimed for payment and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying
Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
 Every substitute Note issued pursuant to the provisions of this Section 2.07 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued
hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost
or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other
securities without their surrender. 
 Section 2.08. Temporary Notes. Pending the preparation of Notes in certificated form, the
Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any
authorized denomination, and substantially in the form of the Notes in certificated form but with such omissions, insertions and variations as may be 

  

 -19- 








 
appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the
Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay the Company will execute and deliver to the Trustee or such
authenticating agent Notes in certificated form (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant
to Section 5.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Company at
its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and
delivered hereunder. 
 Section 2.09. Cancellation of Notes Paid, Etc. All Notes surrendered for the purpose of payment,
repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to
the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary
procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request. If the Company shall acquire any of the Notes, such acquisition shall not operate as satisfaction of the
indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 
 Section 2.10.
CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Noteholders as a convenience to them;
provided, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on
the Notes. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. Until such time as the Company notifies the Trustee to remove the restrictive legend as set forth in Section 2.06(d) from the
Notes or a transfer of Notes from a Restricted Global Note to an Unrestricted Global Note is otherwise made pursuant to the terms hereof, the restricted CUSIP will be the CUSIP number for the Notes. At such time as the Company notifies the Trustee
to remove the restrictive legend as set forth in Section 2.06(d) from the Notes, such legend shall be deemed removed from any Global Notes and an unrestricted CUSIP number for the Notes shall be deemed to be the CUSIP number for the Notes.

 Section 2.11. Additional Notes; Repurchases. The Company may, without the consent of the Noteholders and notwithstanding
Section 2.01, reopen this Indenture and increase the principal amount of the Notes by issuing additional Notes in the future pursuant to this Indenture with the same terms and with the same CUSIP number as the Notes initially issued hereunder
in an unlimited aggregate principal amount, which will form the same series with the Notes initially issued hereunder, provided that no such additional Notes may be issued unless they will be fungible with the original Notes for U.S. federal
income tax and securities law purposes. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and
Opinion of Counsel to cover such matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request. The Company may also from time to time repurchase the Notes in open market purchases or negotiated transactions
without prior notice to Noteholders.

 Section 2.12. Automatic Exchange From Restricted Global Note to Unrestricted Global Note.
Beneficial interests in a Global Note that is subject to restrictions set out in Section 2.06(d) (including the legend set forth in Section 2.06(d)) (the “Restricted Global Note”) may be automatically exchanged, at the
election of the Company, into beneficial interests in an unrestricted Global Note that is no longer subject to the restrictions set out in Section 2.06(d) (including removal of the legend set forth in Section 2.06(d)) (the
“Unrestricted Global Note”) without any action required by or on behalf of the Noteholder (the “Automatic Exchange”). In order to effect such exchange, the Company shall at least 15 days but not more than thirty
days prior to the automatic exchange date, deliver a notice of Automatic Exchange (an “Automatic Exchange Notice”) to each Noteholder at such Noteholder’s address appearing in the Note Register, with a copy to the Trustee. The
Automatic Exchange Notice shall identify the Notes subject to the Automatic Exchange and shall state: (1) the date of the Automatic Exchange; (2) the section of this Indenture pursuant to which the Automatic Exchange shall occur;
(3) the “CUSIP” number of the Restricted Global Note from which such Noteholders’ beneficial interests will be transferred and (4) the “CUSIP” number of the Unrestricted Global Note into which such
Noteholders’ beneficial interests will be transferred. At the Company’s request on no less than 5 days’ prior notice, the Trustee shall deliver, in the Company’s name and at its expense, the Automatic Exchange Notice to each
Noteholder at such Noteholder’s address appearing in the Note Register; provided, however, that the Company shall have delivered to the Trustee an Officers’ Certificate requesting that the Trustee give the Automatic Exchange
Notice (in the name and at the expense of the Company) and setting forth the information to be stated in the Automatic Exchange Notice as provided in the preceding sentence. As a condition to any such exchange pursuant to this Section 2.12, the
Trustee shall be entitled to receive from the Company, and rely conclusively without any liability, upon an Officer’s Certificate and an Opinion of Counsel to the Company, in form and in substance reasonably satisfactory to the Trustee, to the
effect that such transfer of beneficial interests to the Unrestricted Global Note shall be effected in compliance with the Securities Act. Upon such exchange of beneficial interests pursuant to this Section 2.12, the Registrar shall endorse the
Schedule of Increases and Decreases in Global Note to the relevant Notes and reflect on its books and records the date of such transfer and a decrease and increase, respectively, in the principal amount of the applicable Restricted Global Note(s)
and the Unrestricted Global Note, respectively, equal to the principal amount of beneficial interests transferred. If an Unrestricted Global Note is not then outstanding at the time of the Automatic Exchange, the Company shall execute and the
Trustee shall authenticate and deliver an Unrestricted Global Note to the Depositary. Following any such transfer pursuant to this Section 2.12, the relevant Restricted Global Note shall be cancelled.

rule may be amended from time to time. 
 (b) The Company shall deliver to the Trustee within fifteen days after the same is required to be

the Trustee is entitled to conclusively rely exclusively on an Officers’ Certificate). 
 (d) If, at any time during the six-month

securities law or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest will accrue on the Notes at an annual rate of 0.50% per annum of the principal amount of Notes
outstanding for each day during such period for which the Company’s failure to file continues; provided that the Company shall have 14 days, in the aggregate, to cure any such late filings before any Additional Interest shall accrue.

the Notes at an annual rate of 0.50% per annum of the principal amount of Notes outstanding for each day after the 365th day after the last date of original issuance of the Notes until (i) the restrictive legend on the Notes has been
removed in accordance with Section 2.06(d) or Section 2.12, and (ii) the Notes are freely tradable pursuant to Rule 144 without volume restrictions by holders other than the Company’s affiliates (without restrictions pursuant to
U.S. securities law or the terms of this Indenture or the Notes). 
 (f) Additional Interest payable in accordance with Section 5.06(d)
or (e) will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes. 
 Section 5.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force,
or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law,
hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

each Fiscal Year (beginning with the Fiscal Year ending on December 31, 2009) an Officers’ Certificate stating whether or not the signer thereof has knowledge of any failure by the Company to comply with all conditions and covenants then
required to be performed under this Indenture and, if so, specifying each such failure and the nature thereof.

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 7.01(h)
with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company, or a group of Subsidiaries of the Company that in aggregate would constitute a Significant Subsidiary of the Company), unless the principal of all
of the Notes shall have already become due and payable (or waived), either the Trustee or the holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company (and to the Trustee if given by
Noteholders), may declare 100% of the principal of and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on all 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, anything in this Indenture or in the Notes contained to the contrary notwithstanding. 
 In the
event of a declaration of acceleration of the Notes solely because an Event of Default described in Section 7.01(d) has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if
the Event of Default or payment default triggering such Event of Default pursuant to Section 7.01(d) shall be remedied or cured by the Company or a Subsidiary or waived by the holders of the relevant indebtedness within 90 Business Days after
the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of
amounts due on the Notes. 
 If an Event of Default specified in Section 7.01(h) with respect to the Company (and not solely with
respect to a Significant Subsidiary of the Company, or a group of Subsidiaries of the Company that in aggregate would constitute a Significant Subsidiary of the Company) occurs and is continuing, the principal of all the Notes and accrued and unpaid
interest and accrued and unpaid Additional Interest, if any, shall be immediately due and payable. This provision, however, is subject to the conditions that if, at any time after the principal of 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 

  

 -28- 








 
or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid
interest and accrued and unpaid Additional Interest, if any, 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 and
accrued and unpaid Additional Interest, if any (to the extent that payment of such interest is enforceable under applicable law), and on such principal at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to
Section 8.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all Events of Defaults under this Indenture, other than the nonpayment of principal of and accrued
and unpaid interest and accrued and unpaid Additional Interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 7.07, then and in every such case the holders of a
majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes (other than a Default or an Event of Default resulting
from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) and
rescind and annul such declaration and its consequences (other than a declaration or consequences, as the case may be, resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion,
cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) and such Default (other than a Default resulting from a failure to repurchase any Notes when required upon a Fundamental Change or
a failure to deliver, upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) shall cease to exist, and any Event of Default arising therefrom (other than a Default
resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion)
shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon.

 Section 7.03. Additional Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary (except as
provided in Section 5.06(d) or 5.06(e)), if the Company so elects, the sole remedy of Noteholders for an Event of Default relating to any obligation to file reports as required under Section 5.06(a) or (b) shall, for the first 365
days after the occurrence of such an Event of Default which will be the 60th day after written notice is provided to the Company in accordance with Section 7.01(c)), consist exclusively of the right to receive Additional Interest on the Notes
at an annual rate equal to (x) 0.25% of the outstanding principal amount of the Notes for the first 180 days an Event of Default is continuing in such 365-day period and (y) 0.50% of the outstanding principal amount of the Notes for the
remaining 185 days an Event of Default is continuing in such 365-day period. Additional Interest shall be payable in arrears on each Interest Payment Date following the occurrence of such Event of Default in the same manner as regular interest on
the Notes. The Company may elect to pay Additional Interest as the sole remedy under this Section 7.03 by giving notice to the holders, the Trustee and Paying Agent of such election on or before the close of business on the 5th Business Day
after the date on which such Event of Default otherwise would occur. If the Company fails to timely give such notice or pay Additional Interest, the Notes will be immediately subject to acceleration as provided in Section 7.02. On the 366th day
after such Event of Default (if such violation is not cured or waived prior to such 366th day), the Notes will be subject to acceleration as provided in Section 7.02. This Section 7.03 shall not affect the rights of the Noteholders in the
event of the occurrence of any other Event of Default. In the event the Company does not elect to pay Additional Interest upon an Event of Default in accordance with this Section, the Notes will be subject to acceleration as provided in
Section 7.02. Whenever in this Indenture there is mentioned, in any context, the payment of interest on, or in respect of, any Note, such mention 

  

 -29- 








 
shall be deemed to include mention of the payment of “Additional Interest” provided for in this Section 7.03 and Sections 5.06(d) and 5.06(e)
to the extent that, in such context, Additional Interest is, was or would be payable in respect thereof pursuant to the provisions of such sections, and express mention of the payment of Additional Interest (if applicable) in any provision shall not
be construed as excluding Additional Interest in those provisions where such express mention is not made. 
 Section 7.04. Payments
of Notes on Default; Suit Therefor. If an Event of Default under clause (a) or (b) of Section 7.01 shall have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the holders of
the Notes, the whole amount then due and payable on the Notes for principal and interest and Additional Interest, if any, with interest on any overdue principal, interest and Additional Interest, if any, at the rate borne by the Notes at such time,
and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 8.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as
trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the
Notes and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 
 In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under any
Bankruptcy Law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the
Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether
the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 7.04, 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 and accrued and unpaid Additional Interest, if any, in respect of the Notes, and,
in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Noteholders 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 8.06; and any receiver, assignee or trustee
in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders 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 Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agent’s and counsel fees, and including any other amounts due to the
Trustee under Section 8.06 hereof, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied
for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the holders of the Notes may be entitled to receive in such proceedings,
whether in liquidation or under any plan of reorganization or arrangement or otherwise. 
  

 -30- 








 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or
adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Noteholder or the rights of any Noteholder thereof, or to authorize the Trustee to vote in respect of the claim of any Noteholder in
any such proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the
Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes.

 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which
the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because
of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Noteholders, 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 Noteholders, and the Trustee shall continue as though no such proceeding had been instituted. 

Section 7.05. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 7 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 8.06; 
 Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on the Notes,
including Additional Interest, if any, in default in the order of the date due of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the
rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto; 
 Third, in case the
principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount including the payment of the Fundamental Change Repurchase Price and the cash component of the Conversion
Obligation, if any, then owing and unpaid upon the Notes for principal and interest, including Additional 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, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and 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 and accrued and
unpaid interest, and Additional Interest, if any; and 
  

 -31- 








 Fourth, to the payment of the remainder, if any, to the Company. 
 Section 7.06. Proceedings by Noteholders. No holder of any Note shall have any right by virtue of or by availing itself of any provision of
this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy
hereunder, unless (i) such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided; (ii) the holders of not less than 25% in aggregate principal
amount of the Notes then outstanding shall have made written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; (iii) such holders shall have offered to the Trustee such security or
indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby; (iv) the Trustee for sixty days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused
to institute any such action, suit or proceeding and (v) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the holders of a majority in principal amount of the
Notes outstanding within such sixty-day period pursuant to Section 7.09; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee that no one or
more Noteholders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Noteholder, or to obtain or seek to obtain priority over or
preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Noteholders (except as otherwise provided herein). For the protection and
enforcement of this Section 7.06, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any Noteholder to receive payment of the principal of (including the Fundamental Change Repurchase Price upon
repurchase pursuant to Section 16.02), and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to
institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such Noteholder. 
 Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder
of any other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein. 
 Section 7.07. Proceedings by Trustee. In case of an Event of Default the Trustee may in its discretion proceed to protect and enforce the
rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

 Section 7.08. Remedies Cumulative and Continuing. Except as provided in the second paragraph of Section 2.07 and
Section 7.04, all powers and remedies given by this Article 7 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the
Trustee or the holders of the 

  

 -32- 








 
Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no
delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or any
acquiescence therein; and, subject to the provisions of Section 7.06, every power and remedy given by this Article 7 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient,
by the Trustee or by the Noteholders. 
 Section 7.09. Direction of Proceedings and Waiver of Defaults by Majority of
Noteholders. The holders of a majority in aggregate principal amount of the Notes at the time outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other holder or that would involve the Trustee in
personal liability. The holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except
(i) a default in the payment of accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to
the provisions of Section 7.01, (ii) a failure by the Company to deliver cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, upon conversion of the Notes or (iii) a default in respect of a
covenant or provision hereof which under Article 11 cannot be modified or amended without the consent of each holder of an outstanding Note affected. 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 7.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon. 
 Section 7.10. Notice of Defaults. The Trustee shall, within ninety
days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, mail to all Noteholders as the names and addresses of such holders appear upon the Note Register, notice of all Defaults known to a
Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; and provided that, except in the case of a Default in the payment of the principal of, accrued and unpaid interest or accrued and
unpaid Additional Interest, if any, on any of the Notes, including without limiting the generality of the foregoing any Default in the payment of any Fundamental Change Repurchase Price, then in any such event the Trustee shall be protected in
withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders. 
 Section 7.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of any Note by its acceptance thereof shall be
deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the 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 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; 

  

 -33- 








 
provided that the provisions of this Section 7.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding, or to any suit instituted by any Noteholder for the enforcement of the payment of the
principal of accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price with respect to the Notes being repurchased as provided in this
Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 15.

waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived) the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own
affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the holders unless such holders
have offered to the Trustee reasonable indemnity or security against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 
 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly negligent
failure to act or its own willful misconduct, except that 
 (a) prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default that may have occurred: 
 (i) the duties and obligations of the Trustee shall be
determined solely by the express provisions of this Indenture and, after it has been qualified thereunder, the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set
forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and 
 (ii) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any
certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the
Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

  

 -34- 








 (b) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 
 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the
Notes at the time outstanding relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 
 (d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording
protection to, the Trustee shall be subject to the provisions of this Section; 
 (e) the Trustee shall not be liable in
respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-registrar with respect to the Notes;

 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires
notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless such Responsible Officer of the Trustee had actual knowledge of such event; 

(g) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest
bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or
the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any
amounts held hereunder in the absence of such written investment direction from the Company; and 
 (h) in the event that the
Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 8 shall also be afforded to such Custodian, Note Registrar,
Paying Agent, Conversion Agent or transfer agent. 
 None of the provisions contained in this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 
 Section 8.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 8.01: 
 (a) the Trustee may conclusively rely and shall be fully protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, Note, coupon or other paper

therein or thereby; 
 (e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense
of the Company and shall incur no liability of any kind by reason of such inquiry or investigation; 
 (f) the Trustee may
execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any

 (g) the permissive rights of the Trustee
enumerated herein shall not be construed as duties. 
 In no event shall the Trustee be liable for any consequential loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than any such loss or damage caused by the Trustee’s willful
misconduct or gross negligence. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of
Default or (2) written notice of such Default or Event of Default shall have been given to a Responsible Officer of the Trustee by the Company or by any holder of the Notes. 
 Section 8.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate
of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes.
The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 
  

 -36- 








 Section 8.04. Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes. The
Trustee, any Paying Agent, any Conversion Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying Agent, Conversion Agent or
Note Registrar. 
 Section 8.05. Monies to Be Held in Trust. All monies received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for
interest on any money received by it hereunder except as may be agreed from time to time by the Company and the Trustee. 
 Section 8.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it
hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse
the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the reasonable
compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its gross negligence, willful misconduct or bad
faith. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless
against, any loss, claim, damage, liability or expense incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case
may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The
obligations of the Company under this Section 8.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim to which the Notes are hereby made
subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 7.05, funds held in trust herewith for the benefit of the holders of particular Notes. The Trustee’s right to receive payment
of any amounts due under this Section 8.06 shall not be subordinate to any other liability or indebtedness of the Company (even though the Notes may be so subordinated). The obligation of the Company under this Section 8.06 shall survive
the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification
provided in this Section 8.06 shall extend to the officers, directors, agents and employees of the Trustee and shall survive the termination of this Indenture and the resignation or removal of the Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur
expenses or render services after an Event of Default specified in Section 7.01(g) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar
laws. 
 Section 8.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 8.01, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in 

  

 -37- 








 
the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall be full warrant to the
Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 
 Section 8.08.
Conflicting Interests of Trustee. After qualification of this Indenture under the Trust Indenture Act, if the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
(a) eliminate such interest within ninety days, (b) apply to the Commission for permission to continue as Trustee or (c) resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act
and this Indenture. 
 Section 8.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a
Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any
supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 8.10. Resignation or Removal of Trustee. 
 (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the Noteholders at their addresses as they shall appear on the Note Register. Upon
receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee
and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within sixty days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten
Business Days’ notice to the Company and the Noteholders, petition any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may,
subject to the provisions of Section 7.11, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper
and prescribe, appoint a successor trustee. 
 (b) In case at any time any of the following shall occur: 
 (i) the Trustee shall fail to comply with Section 8.08 within a reasonable time after written request therefor by the Company or by
any Noteholder who has been a bona fide holder of a Note or Notes for at least six months, or 
 (ii) the Trustee shall cease
to be eligible in accordance with the provisions of Section 8.09 and shall fail to resign after written request therefor by the Company or by any such Noteholder, or 
 (iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
  

 -38- 








 then, in any such case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.11, any
Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c) The holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with Section 9.04, may at any time remove the Trustee and nominate a successor trustee
that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Noteholder, upon the terms and conditions and
otherwise as in Section 8.10(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in
Section 8.11. 
 Section 8.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in
Section 8.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless,
on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.06, execute and deliver an instrument transferring to such
successor trustee all the rights and powers of the trustee so ceasing to act. 
 Upon request of any such successor trustee, the Company
shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes
are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of
Section 8.06. 
 No successor trustee shall accept appointment as provided in this Section 8.11 unless at the time of such
acceptance such successor trustee shall be qualified under the provisions of Section 8.08 and be eligible under the provisions of Section 8.09. 
 Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, each of the Company and the successor trustee, at the written direction and at the expense of the Company, shall mail or
cause to be mailed notice of the succession of such trustee hereunder to the Noteholders at their addresses as they shall appear on the Note Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
  

 -39- 








 Section 8.12. Succession by Merger, Etc. Any corporation or other entity into which the
Trustee may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding
to all or substantially all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part
of any of the parties hereto, provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation or other entity shall be qualified under the
provisions of Section 8.08 and eligible under the provisions of Section 8.09. 
 In case at the time such successor to the Trustee
shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent
appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee
may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture
provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall
apply only to its successor or successors by merger, conversion or consolidation. 
 Section 8.13. Limitation on Rights of Trustee as
Creditor. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), after qualification under the Trust Indenture Act, the Trustee shall be subject to the provisions of the Trust Indenture Act
regarding the collection of the claims against the Company (or any such other obligor). 
 Section 8.14. Trustee’s Application
for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the holders
of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission
shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than
three Business Days after the date any officer that the Company has indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless,
prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted.

 ARTICLE 9 
 CONCERNING THE
NOTEHOLDERS 
 Section 9.01. Action by Noteholders. Whenever in this Indenture it is provided that the holders of a specified
percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such
action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or
(b) by the 

  

 -40- 








 
record of the Noteholders voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article 10, or
(c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may, but
shall not be required to, fix in advance of such solicitation, a date as the record date for determining Noteholders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of
commencement of solicitation of such action. 
 Section 9.02. Proof of Execution by Noteholders. Subject to the provisions of
Section 8.01, Section 8.02 and Section 10.05, proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Noteholders’ meeting shall be proved in the manner
provided in Section 10.06. 
 Section 9.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating
agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be
overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to
Section 2.03) accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion
Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon its order, shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for monies payable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against
the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the
provisions of this Indenture. 
 Section 9.04. Company-Owned Notes Disregarded. In determining whether the holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of
this Section 9.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company or a Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee,
the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to
Section 8.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such
determination.

after) the evidencing to the Trustee, as provided in Section 9.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of
a Note that is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 9.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and of any
Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of
transfer thereof.

 (i) make any change in this Article 11 that requires each holder’s consent or in the waiver provisions in Section 7.01 or
Section 7.09, 
 in each case without the consent of each holder of an outstanding Note affected. 
 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Noteholders as aforesaid and subject to
Section 11.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 
  

 -45- 








 It shall not be necessary for the consent of the Noteholders under this Section 11.02 to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. After an amendment under this Indenture becomes effective, the Company shall mail to the holders a notice briefly
describing such amendment. However, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the amendment. 
 Section 11.03. Effect of Supplemental Indentures. Any supplemental indenture executed pursuant to the provisions of this Article 11 shall
comply with the Trust Indenture Act, as then in effect; provided that this Section 11.03 shall not require such supplemental indenture to be qualified under the Trust Indenture Act prior to the time such qualification is in fact required
under the terms of the Trust Indenture Act or this Indenture has been qualified under the Trust Indenture Act, nor shall any such qualification constitute any admission or acknowledgment by any party to such supplemental indenture that any such
qualification is required prior to the time such qualification is in fact required under the terms of the Trust Indenture Act or this Indenture has been qualified under the Trust Indenture Act. Upon the execution of any supplemental indenture
pursuant to the provisions of this Article 11, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the
Trustee, the Company and the Noteholders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 
 Section 11.04. Notation on Notes.
Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 11 may, at the Company’s expense, bear a notation as to any matter provided for in such supplemental indenture. If
the Company shall so determine, new Notes so modified as to conform, in the opinion of the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and
executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.10) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding.

 Section 11.05. Evidence of Compliance of Supplemental Indenture to Be Furnished to Trustee. In addition to the documents
required by Section 17.05, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 11 and
is permitted or authorized by the Indenture. 
 ARTICLE 12 
 CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 
 Section 12.01. Company May Consolidate, Etc. on
Certain Terms. Subject to the provisions of Section 12.02, the Company shall not consolidate with, merge with or into, or convey, transfer or lease all or substantially all of its properties and assets to another Person, unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a
corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume,
by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the Notes and this Indenture; and 
  

 -46- 








 (b) immediately after giving effect to such transaction, no Default or Event of Default
shall have occurred and be continuing under this Indenture. 
 Upon any such consolidation, merger, conveyance, transfer or lease the
Successor Company (if not the Company) shall succeed to, and may exercise every right and power of, the Company under this Indenture. 
 For
purposes of this Section 12.01, the 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, 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, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company to another Person. 
 Section 12.02. Successor Corporation to Be Substituted. In case of any such consolidation, merger, conveyance, transfer or lease and upon the
assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of, accrued and unpaid interest and accrued and unpaid
Additional Interest, if any, on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this
Indenture to be performed by the Company, such Successor Company shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to
be signed, and may issue in its own name any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and
subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that such Successor Company thereafter shall cause to be
signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, conveyance or transfer (but not in the case of a lease), the Person named as the “Company” in the
first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person
shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture. 
 In case of any
such consolidation, merger, 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 12.03. Opinion of Counsel to Be Given to Trustee. The Company shall not effect any merger, consolidation, conveyance, transfer or
lease referred to in Section 12.01 unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, conveyance, transfer or lease and any such assumption and,
if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 12.

the Company or of any successor corporation or entity, either directly or through the Company or any successor corporation or entity, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty
or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issuance of the Notes. 
 ARTICLE 14 
 [INTENTIONALLY OMITTED]

 ARTICLE 15 
 CONVERSION OF NOTES

 Section 15.01. Conversion Privilege. 
 (a) Upon compliance with the provisions of this Article 15, a Noteholder shall have the right, at such holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or
an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions set forth in Section 15.01(b), at any time prior to January 13, 2014 under the circumstances and during the periods set forth in
Section 15.01(b), and (ii) irrespective of the conditions set forth in Section 15.01(b), on or after January 13, 2014 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date,
in each case, at an initial conversion rate (the “Conversion Rate”) of 21.0235 shares of Common Stock (subject to adjustment as provided in Section 15.04 of this Indenture) per $1,000 principal amount of Notes (subject to the
settlement provisions of Section 15.02, the “Conversion Obligation”). 
 (b)(i) Prior to the second Scheduled Trading
Day immediately preceding the Maturity Date, the Notes may be surrendered for conversion during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading
Price per $1,000 principal amount of Notes for each day of such Measurement Period was less than 98% of the product of the then-applicable Conversion Rate on such Trading Day and the Last Reported Sale Price of the Common Stock on such Trading Day.
The Company shall have no obligation to determine the Trading Price of the Notes unless a Noteholder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of the product
of the then-applicable Conversion Rate and the Last Reported Sale Price of the Common Stock at such time, at which time the Company shall determine, or shall instruct the Trustee to determine, the Trading Price of the Notes beginning on the next
Trading Day and on each successive Trading Day until the Trading Price per Note is greater than or equal to 98% of the product of the then-applicable Conversion Rate and the Last Reported Sale Price of the Common Stock on such Trading Day. If the
Company does not determine the Trading Price of the Notes as provided in the preceding sentence, then 

  

 -48- 








 
the Trading Price per $1,000 principal amount of Notes will be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock
and the then-applicable Conversion Rate. If the Trading Price condition set forth above has been met, the Company shall so notify the Noteholders, the Trustee and the Conversion Agent. 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 98% of the product of the then-applicable Conversion Rate and the Last Reported Sale Price of the Common Stock on such Trading Day, the Company shall so
notify the holders of the Notes, the Trustee and the Conversion Agent. 
 (ii) In the event that the Company elects to:

 (A) distribute to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for
a period of not more than sixty calendar days after the record date for such distribution, to subscribe for or purchase its Common Stock, at a price per share less than the Last Reported Sale Price of the Common Stock for the Trading Day immediately
preceding the declaration date for such distribution; or 
 (B) distribute to all or substantially all holders of its Common
Stock the Company’s assets, debt securities, or rights to purchase securities of the Company, which distribution has a per share value (as determined by the Board of Directors) exceeding 10% of the Last Reported Sale Price of the Common Stock
on the Trading Day immediately preceding the date of declaration for such distribution, 
 then, in each case, the Company shall notify all holders of the
Notes, the Trustee and the Conversion Agent not less than thirty-five Business Days prior to the Ex-Dividend Date for such distribution. Once the Company has given such notice, the Notes may be surrendered for conversion at any time until the
earlier of (1) the close of business on the second Scheduled Trading Day immediately prior to such Ex-Dividend Date and (2) the Company’s announcement that such distribution will not take place, even if the Notes are not otherwise
convertible at such time. No Noteholder may exercise this right to convert if the Noteholder otherwise may participate in the distribution without conversion (based upon the then-applicable Conversion Rate and upon the same terms as holders of the
Company’s Common Stock). 
 (iii) In the event of a Fundamental Change (determined without regard to the proviso to such
definition) or a Make-Whole Fundamental Change, a Noteholder may surrender Notes for conversion at any time from and after the forty-fifth Business Day prior to the anticipated effective date of such Fundamental Change or a Make-Whole Fundamental
Change, as the case may be, until the second Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date corresponding to such Fundamental Change (or, in the case of a Make-Whole Fundamental Change that does not constitute a
Fundamental Change by virtue of the parenthetical in the definition of Make-Whole Fundamental Change, the twenty-fifth Trading Day immediately following such effective date). The Company shall give notice of the anticipated effective date of any
Fundamental Change or Make-Whole Fundamental Change, as the case may be, as soon as practicable after the Company first determines the anticipated effective date of such Fundamental Change or Make-Whole Fundamental Change, as the case may be, and
shall use commercially reasonable efforts to make such determination in time to give such notice fifty Business Days in advance of such anticipated effective date; provided that the Company will not be required to give such notice more than
fifty Business Days in advance of such anticipated effective date. 
 (iv) Prior to the second Scheduled Trading Day immediately preceding
the Maturity Date, the Notes may be surrendered for conversion in any Fiscal Quarter after the Fiscal Quarter ending 

  

 -49- 








 
December 31, 2009, and only during such Fiscal Quarter, if the Last Reported Sale Price of the Common Stock for at least twenty Trading Days in a period
of thirty consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding Fiscal Quarter is equal to or more than 130% of the then-applicable Conversion Price on the last day of such preceding Fiscal Quarter
(such price, the “Conversion Trigger Price”). The Company shall determine, at the beginning of each Fiscal Quarter commencing after December 31, 2009, whether the Notes may be surrendered for conversion in accordance with this
clause (iv) and shall notify the Trustee. 
 Section 15.02. Conversion Procedure. 
 (a) [Reserved] 
 (b) Subject to this
Section 15.02, upon any conversion of any Note, the Company shall deliver to converting Noteholders, in respect of each $1,000 principal amount of Notes being converted, solely cash, solely shares of Common Stock or a combination of cash and
Common Stock (the “Settlement Amount”), at its election, as set forth in this Section 15.02. 
 (i) All
conversions on or after January 13, 2014 will be settled using the same Settlement Method. 
 (ii) Prior to
January 13, 2014, the Company will elect (or be deemed to have elected) the same Settlement Method for all conversions occurring on any given Conversion Date. Except for any conversions that occur on or after January 13, 2014, the Company
need not elect the same Settlement Method with respect to conversions that occur on different Trading Days. 
 (iii) If, in
respect of any Conversion Date (or the period beginning on, and including, January 13, 2014 and ending on, and including, the second Scheduled Trading Day immediately preceding the Maturity Date, as the case may be), the Company elects to
deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to
converting Noteholders no later than the second Trading Day immediately following the relevant Conversion Date. Such Settlement Notice shall specify whether the Company shall satisfy its Conversion Obligation by (A) delivering solely shares of
Common Stock, (B) paying solely cash or (C) paying and delivering, as the case may be, a combination of cash and shares of Common Stock. In the case of an election to pay and deliver, as the case may be, a combination of cash and shares of
Common Stock, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company does not deliver a Settlement Notice, the Company will be deemed to have elected to deliver a combination of cash and shares of Common Stock in
respect of its Conversion Obligation, and the Specified Dollar Amount shall be deemed to be equal to $1,000. If the Company delivers a Settlement Notice electing to pay and deliver, as the case may be, a combination of cash and shares of Common
Stock in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount in such Settlement Notice, the Specified Dollar Amount shall be deemed to be equal to $1,000. 
 (iv) The Settlement Amount in respect of any conversion of Notes shall be computed as follows: 
 (A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by delivering solely Common Stock, the
Company will deliver to the converting Noteholder a number of shares of Common Stock equal to (1)(i) the aggregate principal amount of Notes to be converted, divided by (ii) $1,000, multiplied by (2) the then-applicable
Conversion Rate; 
  

 -50- 








 (B) if the Company elects to satisfy its Conversion Obligation in respect of such
conversion by paying solely cash, the Company shall pay to the converting Noteholder, cash in an amount per $1,000 principal amount of Notes being converted equal to the sum of the Daily Conversion Values for each of the forty consecutive Trading
Days during the related Cash Settlement Averaging Period; and 
 (C) if the Company elects to satisfy its Conversion
Obligation in respect of such conversion by paying and delivering, as the case may be, a combination of cash and shares of Common Stock, if any, the Company shall pay and deliver to the converting Noteholder, as the case may be, in respect of each
$1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the forty consecutive Trading Days during the related Cash Settlement Averaging Period. 
 (v) The Company will also deliver to each converting Noteholder cash in lieu of fractional shares of Common Stock as set forth pursuant to
clause (l) below. 
 (vi) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable)
shall be determined by the Company promptly following the last day of the Cash Settlement Averaging Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash
deliverable in lieu of fractional shares (if any), the Company shall notify the Trustee and the Conversion Agent of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash deliverable in lieu of
fractional shares of Common Stock. The Trustee and the Conversion Agent shall have no responsibility for any such determination. 
 (c)
[Reserved] 
 (d) Before any holder of a Note shall be entitled to convert the same as set forth above, such holder shall (i) in the
case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to the amount of interest and Additional Interest, if any, payable on the next Interest Payment Date to which such holder is
not entitled as set forth in Section 15.02(j) and, if required, all transfer or similar taxes, if any, and (ii) in the case of a Note issued in certificated form, (1) complete and manually sign and deliver an irrevocable notice to the
Conversion Agent in the form on the reverse of such certificated Note (or a facsimile thereof) (Exhibit B hereto) (a “Notice of Conversion”) at the office of the Conversion Agent and shall 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, if any, to be delivered upon settlement of the Conversion Obligation to be registered,
(2) 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, (3) if required, pay funds equal to interest payable on the next
Interest Payment Date to which such holder is not entitled as set forth in Section 15.02(j), (4) if required, furnish appropriate endorsements and transfer documents, and (5) if required, pay all transfer or similar taxes, if any as
set forth in Section 15.02(g). The Trustee (and if different, the relevant Conversion Agent) shall notify the Company of any conversion pursuant to this Article 15 on the date of such conversion. No Notice of Conversion with respect to any
Notes may be surrendered by a holder thereof if such holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with
Section 16.03, unless the Company defaults in the payment of the Fundamental Change Repurchase Price. 
  

 -51- 








 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, if any, that shall be payable upon conversion 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.

 (e) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that the holder has complied with the requirements set forth in clause (d) of this Section 15.02. The Company shall pay and deliver, as the case may be, the cash and/or shares of Common Stock due in respect of its
Conversion Obligation (i) for conversions that occur prior to January 13, 2014, on the third Trading Day immediately following the relevant Conversion Date, if the Company elects to satisfy the related Conversion Obligation solely in
shares of Common Stock (provided that if calculating any adjustment to the Conversion Rate in accordance with Section 15.04 cannot be accomplished prior to such third Trading Day following the relevant Conversion Date, the Company shall deliver
the additional shares of Common Stock resulting from that adjustment on the third Trading Day after the earliest Trading Day on which such calculation can be made and provided further that if application of this sentence would otherwise result in
the settlement of a conversion during the 10 Trading Days immediately following the effective date of a Fundamental Change settlement will instead take place on the tenth Trading Day following that effective date), (ii) for conversions that
occur on or after January 13, 2014 and if the Company elects to satisfy the related Conversion Obligation solely in shares of Common Stock, on the Maturity Date or (iii) by the third Trading Day immediately following the last Trading Day
of the Cash Settlement Averaging Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Noteholders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such
Noteholder, or such Noteholder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock to which such Noteholder shall be entitled in satisfaction of such Conversion
Obligation. 
 (f) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate
and deliver to or upon the written order of the holder of the Note so surrendered, without charge to such holder, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered
Note. 
 (g) If a holder submits a Note for conversion, the Company shall pay all stamp and other duties, if any, that may be imposed by the
United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares of Common Stock, if any, upon the conversion. However, the holder shall pay any such tax that is due because the holder
requests any shares of Common Stock to be issued in a name other than the holder’s name. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the holder’s
name until the Trustee receives a sum sufficient to pay any tax that will be due because the shares are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations.

 (h) Except as provided in Section 15.04, no adjustment shall be made for dividends on any shares issued upon the conversion of any
Note as provided in this Article. 
 (i) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction
of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than
the Trustee. 
  

 -52- 








 (j) Upon conversion, a Noteholder shall not receive any additional cash payment for accrued and unpaid
interest and Additional Interest, if any, except as set forth below. The Company’s settlement of the Conversion Obligations pursuant to Section 15.02 shall be deemed to satisfy its obligation to pay the principal amount of the Note and
accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date shall be deemed to be paid
in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after the close of business on a Interest Record Date, holders of such Notes as of the close of business on the Interest Record
Date will receive the interest and Additional Interest, if any, payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion of such Notes at any time after the close of business on the applicable Interest Record
Date. Notes surrendered for conversion during the period from the close of business on any Interest Record Date to the opening of business on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest
and Additional Interest, if any, payable on the Notes so converted; provided, however, that no such payment shall be required (1) if the Company has specified a Fundamental Change Repurchase Date that is after a Interest Record
Date but on or prior to the corresponding Interest Payment Date, (2) to the extent of any Defaulted Interest, if any, existing at the time of conversion with respect to such Note or (3) if the Notes are surrendered for conversion after the
close of business on the Interest Record Date immediately preceding the Maturity Date. Except as set forth in this Section 15.02(j), no payment or adjustment will be made for accrued and unpaid interest and Additional Interest, if any, on
converted Notes. 
 (k) 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 relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation solely in shares of Common Stock) or the last Trading Day of the related Cash
Settlement Averaging Period (in the case of any other Settlement Method), as the case may be; provided, however, if such Conversion Date or such last Trading Day of the Cash Settlement Averaging Period occurs on any date when the stock
transfer books of the Company shall be closed, such occurrence shall not be effective to constitute the Person or Persons entitled to receive any such shares of Common Stock due upon conversion as the record holder or holders of such shares of
Common Stock on such date, but such occurrence shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next
succeeding day on which such stock transfer books are open. Upon conversion of Notes, such Person shall no longer be a Noteholder. 
 (l) For
each Note surrendered for conversion, if the Company has elected to deliver a combination of cash and shares of Common Stock in respect of its Conversion Obligation, the number of full shares that shall be issued upon conversion thereof shall be
computed on the basis of the aggregate Daily Settlement Amounts for the applicable Cash Settlement Averaging Period and any fractional shares remaining after such computation shall be paid in cash. If more than one Note shall be surrendered for
conversion at one time by the same holder, the number of full shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. The
Company shall not issue fractional shares of Common Stock upon conversion of Notes. Instead, the Company shall pay cash in lieu of fractional shares based on the Daily VWAP on the relevant Conversion Date (if the Company elects to satisfy its
Conversion Obligation solely in shares of Common Stock) or based on the Daily VWAP on the last Trading Day of the relevant Cash Settlement Averaging Period (in the case of any other Settlement Method).

 Section 15.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection
with Make-Whole Fundamental Changes. 
 (a) Notwithstanding anything herein to the contrary, the Conversion Rate applicable to each Note
that is surrendered for conversion, in accordance with this Article 15, at any time from, and including, the effective date (the “Effective Date”) of a Make-Whole Fundamental Change until, and including, the close of business on the
second Scheduled Trading Day immediately preceding the related Fundamental Change Repurchase Date corresponding to such Make-Whole Fundamental Change, or the twenty-fifth Trading Day immediately following the Effective Date of such Make-Whole
Fundamental Change (in the case of a Make-Whole Fundamental Change that does not constitute a Fundamental Change by virtue of the parenthetical in the definition of Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental
Change Period”), shall be increased to an amount equal to the Conversion Rate that would, but for this Section 15.03, otherwise apply to such Note pursuant to this Article 15, plus an amount equal to the Make-Whole Conversion
Rate Adjustment. 
 As used herein, “Make-Whole Conversion Rate Adjustment” shall mean, with respect to a Make-Whole
Fundamental Change, the amount set forth in the following table that corresponds to the Effective Date of such Make-Whole Fundamental Change and the Stock Price for such Make-Whole Fundamental Change, all as determined by the Company:

 provided, however, that: 
 (i) if the actual Stock Price of such Make-Whole Fundamental Change is between two Stock Prices listed in the table above under the row
titled “Stock Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the table above in the column immediately below the title “Effective Date,” then the Make-Whole
Conversion Rate Adjustment for such Make-Whole Fundamental Change shall be determined by the Company by straight-line interpolation between the Make-Whole Conversion Rate Adjustment set forth for such higher and lower Stock Prices, or for such
earlier and later Effective Dates based on a 365 day year, as applicable; 
 (ii) if the actual Stock Price of such Make-Whole
Fundamental Change is greater than $250.00 per share (subject to adjustment in the same manner as the Stock Price as provided in clause (iii) below), or if the actual Stock Price of such Make-Whole Fundamental Change is less than $40.31 per
share (subject to adjustment in the same manner as the Stock Price as 

  

 -54- 








 
provided in clause (iii) below), then the Make-Whole Conversion Rate Adjustment shall be equal to zero and this Section 15.03 shall not require the
Company to increase the Conversion Rate with respect to such Make-Whole Fundamental Change; 
 (iii) if an event occurs that
requires, pursuant to this Article 15 (other than solely pursuant to this Section 15.03), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each price set forth in the table above
under the row titled “Stock Price” shall be deemed to be adjusted so that such Stock Price, at and after such time, shall be equal to the product of (1) such Stock Price as in effect immediately before such adjustment to such Stock
Price and (2) a fraction whose numerator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be in effect, in accordance with this Article 15, immediately
after such adjustment to the Conversion Rate; 
 (iv) [Reserved]; 
 (v) each Make-Whole Conversion Rate Adjustment set forth in the table above shall be adjusted in the same manner in which, at the same
time and for the same events for which, the Conversion Rate is to be adjusted pursuant to Section 15.04; and 
 (vi) in
no event will the total number of shares of Common Stock issuable upon conversion of the Notes exceed 24.8077 per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 15.04.

 (b) As soon as practicable after the Company determines the anticipated Effective Date of any proposed Make-Whole Fundamental Change, the
Company shall mail to each Noteholder, the Trustee and the Conversion Agent written notice of, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the
Company’s website, the anticipated Effective Date of such proposed Make-Whole Fundamental Change and shall use commercially reasonable efforts in time to give such notice fifty Business Days in advance of such anticipated Effective Date;
provided that the Company shall not be required to give such notice or issue such press release more than fifty Business Days in advance of such anticipated Effective Date. Each such press release notice, announcement and publication shall
also state that in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Notes entitled as provided herein to such increase (along with a description of how such
increase shall be calculated and the time periods during which Notes must be surrendered in order to be entitled to such increase). No later than five Business Days after the actual Effective Date of each Make-Whole Fundamental Change, the Company
shall mail to each Noteholder, the Trustee and the Conversion Agent written notice of, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the
Company’s website, such Effective Date and the amount by which the Conversion Rate has been so increased. 
 Nothing in this
Section 15.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 15.04 in respect of a Make-Whole Fundamental Change. 
 Section 15.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows: 
 (a) If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all of the shares of Common Stock, or if the Company effects a share split or share combination of the
Common Stock, the applicable Conversion Rate will be adjusted based on the following formula: 
  

					
	CR = CR0	  	x	  	OS
	  	  	OS0

  

 -55- 








 where 
  

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

 Such adjustment shall become effective immediately after the opening of business on the Ex-Dividend Date for such
dividend or distribution, or the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 15.04(a) is declared but not so paid or made, or the outstanding shares of Common
Stock are not split or combined, as the case may be, 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 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, distribution, share split or share combination had not been declared or announced. 
 (b) If the Company distributes to all or substantially all holders of its Common Stock any rights, options or warrants entitling them for a period of not
more than sixty days from the record date for such distribution to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading
Day period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution, the Conversion Rate shall be increased based on the following formula: 
  

					
	CR = CR0	  	x	  	OS0 + X
	  	  	OS0 + Y

 where 
  

					
			
	CR0	  	=	  	the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

  

 -56- 









					
	CR	  	=	  	the applicable Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such distribution;
			
	OS0	  	=	  	the number of shares of the Common Stock that are outstanding immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	X	  	=	  	the total number of shares of the Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of Common
Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date relating to such distribution of such rights, options or warrants.

 Such adjustment shall be successively made whenever any such rights, options or warrants are distributed and shall
become effective immediately after the opening of business on the Ex-Dividend Date for such distribution. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate
shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually
delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such Ex-Dividend Date for such distribution had not been fixed. 
 For purposes of this Section 15.04(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase
shares of the Common Stock at less than the average of the Last Reported Sale Prices of the Common Stock for each Trading Day in the applicable ten-consecutive-Trading Day period, there shall be taken into account any consideration received by the
Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. In no event shall the Conversion Rate be
decreased pursuant to this Section 15.04(b). 
 (c) If the Company shall distribute shares of its Capital Stock, evidences of its
indebtedness or other of its assets or property other than (i) dividends or distributions (including share splits) covered by Section 15.04(a) or Section 15.04(b), (ii) dividends or distributions paid exclusively in cash and
covered by Section 15.04(d), and (iii) Spin-Offs to which the provisions set forth below in this Section 15.04(c) shall apply (any of such shares of Capital Stock, indebtedness, or other asset or property hereinafter in this
Section 15.04(c) called the “Distributed Property”), to all or substantially all holders of its Common Stock, then, in each such case the Conversion Rate shall be increased based on the following formula: 
  

					
	CR = CR0	  	x	  	            SP0            
	  	  	      SP0 - FMV

 where 
  

					
			
	CR0	  	=	  	the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

  

 -57- 









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

 Such adjustment shall become effective immediately prior to
the opening of business on the Ex-Dividend Date for such distribution; provided that if “FMV” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate provisions shall be made so that each Noteholder shall have the right to receive on conversion in respect of each $1,000 principal amount of the
Notes held by such holder, in addition to the number of shares of Common Stock equal to the Conversion Rate, the amount and kind of Distributed Property such holder would have received had such holder owned a number of shares of Common Stock equal
to the Conversion Rate immediately prior to the Record Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared. If the Board of Directors determines “FMV” for purposes of this Section 15.04(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices
in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

 With respect to an adjustment pursuant to this Section 15.04(c) where there has been a dividend or other distribution on the Common
Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company (a “Spin-Off”), the Conversion Rate will be increased based on the following
formula: 
  

					
	CR = CR0	  	x	  	FMV0 + MP0
	  	  	      MP0

 where 
  

					
			
	CR0	  	=	  	the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for the Spin-Off;
			
	CR	  	=	  	the applicable Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for the Spin-Off;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock over the
first ten consecutive Trading Day period immediately following, and including, the Ex-Dividend Date for the Spin-Off (such period, the “Valuation Period”), and

  

 -58- 









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

 The adjustment to the Conversion Rate under the preceding paragraph of this Section 15.04(c) shall be made
immediately after the opening of business on the day after the last day of the Valuation Period, but shall become effective as of the opening of business on the Ex-Dividend Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than
ten Trading Days prior to, and including, the end of the Cash Settlement Averaging Period in respect of any conversion, if applicable, references within this Section 15.04(c) to ten 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 the Spin-Off to, and including, the last Trading Day of such Cash
Settlement Averaging Period. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the ten Trading Days commencing on the Ex-Dividend Date of any Spin-Off, references in the portion of this
Section 15.04(c) related to Spin-Offs to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, but excluding, the Conversion Date for
such conversion. 
 Subject in all respect to Section 15.10, rights, options or warrants distributed by the Company to all holders of
its Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence
of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common
Stock, shall be deemed not to have been distributed for purposes of this Section 15.04 (and no adjustment to the Conversion Rate under this Section 15.04 will be required) until the occurrence of the earliest Trigger Event, whereupon such
rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 15.04(c). If any such right, option or warrant, including any such existing
rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other
assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing
rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the
preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 15.04 was made, (1) in the case of any such rights, options or
warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may
be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights or
warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the
Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of this
Section 15.04(c), Section 15.04(a), and Section 15.04(b), any dividend or distribution to which this Section 15.04(c) is applicable that also includes shares of Common Stock, or rights, options or warrants to subscribe for or
purchase shares of Common Stock to which Section 15.04(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the 

  

 -59- 








 
evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights, options or warrants to which
Section 15.04(c) applies (and any Conversion Rate adjustment required by this Section 15.04(c) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of
Common Stock or such rights, options or warrants (and any further Conversion Rate adjustment required by Section 15.04(a) and Section 15.04(b) with respect to such dividend or distribution shall then be made), except (A) the
Ex-Dividend Date of such dividend or distribution shall be substituted as “the Ex-Dividend Date,” “the Ex-Dividend Date relating to such distribution of such rights, options or warrants” and “the Ex-Dividend Date for such
distribution” within the meaning of Section 15.04(a) and Section 15.04(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding immediately prior to the Ex-Dividend
Date for such dividend or distribution, or the effective date of such share split or share combination, as the case may be” within the meaning of Section 15.04(a) or “outstanding immediately prior to the Ex-Dividend Date for such
dividend or distribution” within the meaning of Section 15.04(b). 
 In no event shall the Conversion Rate be decreased pursuant to
this Section 15.04(c). 
 (d) If any cash dividend or distribution is made to all or substantially all holders of its outstanding Common
Stock, the applicable Conversion Rate shall be increased based on the following formula: 
  

					
	CR = CR0	  	x	  	        SP0          
	  	  	      SP0 - C

 where 
  

					
			
	CR0	  	=	  	the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR	  	=	  	the applicable Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend
Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company pays or distributes to holders of its Common Stock.

 Such adjustment shall become effective immediately after the opening of business on the Ex-Dividend Date for such
dividend or distribution; provided that if “C” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall
have the right to receive on the date on which the relevant cash dividend or distribution is distributed to holders of Common Stock, for each $1,000 principal amount of Notes, the amount of cash such holder would have received had such holder owned
a number of shares equal to the Conversion Rate on the Record Date for such distribution. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared. 
  

 -60- 








 For the avoidance of doubt, for purposes of this Section 15.04(d), in the event of any
reclassification of the Common Stock, as a result of which the Notes become convertible into more than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant to this Section 15.04(d), references in this Section
to one share of Common Stock or Last Reported Sale Prices of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Notes are then
convertible equal to the numbers of shares of such class issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications. 
 In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(d). 
 (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock and if the cash and
value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading-Day period commencing on, and including, the Trading Day
next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be increased based on the following formula: 
  

					
	CR = CR0	  	x	  	AC + (SP x OS)
	  	  	      OS0 x SP

 where 
  

					
			
	CR0	  	=	  	the applicable Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the Expiration Date;
			
	CR	  	=	  	the applicable Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the Expiration Date;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the time (the “Expiration Time”) such tender or exchange offer expires (prior to giving effect to such
tender offer or exchange offer);
			
	OS	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to such tender offer or exchange offer); and
			
	SP	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.


 Such adjustment under this Section 15.04(e) shall become effective at the opening of business on the Trading
Day next succeeding the Expiration Date. If the Trading Day next succeeding the Expiration Date is less than ten Trading Days prior to, and including, the end of the Cash Settlement Averaging Period in respect of any conversion, references within
this Section 15.04(e) to ten Trading Days shall be deemed replaced, for purposes of calculating the affected daily Conversion Rates in respect of that 

  

 -61- 








 
conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and
including, the last Trading Day of such Cash Settlement Averaging Period. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the ten Trading Days commencing on the Trading Day next succeeding the
Expiration Date, references within this Section 15.04(e) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but
excluding, the Conversion Date for such conversion. If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any or all or any portion of
such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the
purchases that had been effected. In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(e). 
 (f) The term
“Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock (or other security) have the right to receive any cash, securities or other property or in which
the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property
(whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
 (g) Except as stated herein, the Company
shall not adjust the Conversion Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right, option or warrant to purchase shares of its Common Stock or such
convertible or exchangeable securities. 
 (h) Notwithstanding this Section 15.04 or any other provision of this Indenture or the Notes,
if any Conversion Rate adjustment becomes effective, or any Ex-Dividend Date for any issuance, dividend or distribution (relating to a required Conversion Rate adjustment) occurs, during the period beginning on, and including, the open of business
on a Conversion Date and ending on, and including, (x) the close of business on the third Trading Day immediately following the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation solely in shares of
Common Stock) or (y) the close of business on the last Trading Day of a related Cash Settlement Averaging Period (in the case of any other Settlement Method), the Board of Directors shall make adjustments to the Conversion Rate and the amount
of cash or number of shares of Common Stock issuable upon conversion of the Notes, as the case may be, as are necessary or appropriate to effect the intent of this Section 15.04 and the other provisions of this Article 15 and to avoid unjust or
inequitable results, as determined in good faith by the Board of Directors. Any adjustment made pursuant to this Section 15.04(h) shall apply in lieu of the adjustment or other term that would otherwise be applicable. 
 (i) In addition to those required by clauses (a), (b), (c), (d) and (e) of this Section 15.04, and to the extent permitted by applicable
law and subject to the applicable rules of the New York Stock Exchange, the Company from time to time may increase the Conversion Rate by any amount for a period of at least twenty Business Days if the Board of Directors determines that such
increase would be in the Company’s best interest. In addition, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in
connection with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the holder of each Note at its last
address appearing on the Note Register provided for in Section 2.06 a notice of the increase at least fifteen 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. 
  

 -62- 








 (j) The Company shall not take any action that would result in adjustment of the Conversion Rate,
pursuant to this Article 15, in such a manner as to result in the reduction of the Conversion Price to less than the par value per share of Common Stock. 
 (k) The applicable Conversion Rate will not be adjusted: 
 (i) upon the issuance of any
shares of the 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 the Common Stock under
any plan; 
 (ii) upon the issuance of any shares of the 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 the Company’s Subsidiaries; 
 (iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and
outstanding as of the date the Notes were first issued; 
 (iv) for a change in the par value of the Common Stock; 

(v) for accrued and unpaid interest, including Additional Interest, if any; or 
 (vi) for any transactions described in this Section 15.04 if Noteholders participate (as a result of holding the Notes, and at the
same time as holders of Common Stock participate) in such transactions as if such Noteholders held a number shares of Common Stock equal to the Conversion Rate at the time such adjustment would be required, multiplied by the principal amount
(expressed in thousands) of Notes held by such Noteholder, without having to convert their Notes. 
 (l) All calculations and other
determinations under this Article 15 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share. 
 (m) The Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate. However, the Company shall carry forward any adjustments that are less
than 1% of the Conversion Rate and make such carried forward adjustment, regardless of whether the aggregate adjustment is less than 1%, (i) upon any conversion of Notes, and (ii) on each of the forty-two Scheduled Trading Days immediately
preceding the Maturity Date. 
 (n) Except as set forth in this Article 15, the Company shall not adjust the Conversion Rate. 
 (o) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent other than the
Trustee 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


  

 -63- 








 
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 the holder of each Note at its last address appearing on the Note Register provided for in Section 2.06 of this Indenture, within
ten days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 
 (p) If, in respect of any Trading Day within the Cash Settlement Averaging Period for a converted Security: 
 (i)
shares of Common Stock are deliverable with respect to the Daily Settlement Amount for such Trading Day in accordance with this Article 15; 
 (ii) any event that requires an adjustment to the Conversion Rate under any of clauses (a), (b), (c), (d) and (e) of this Section 15.04 has not resulted in an adjustment to the Conversion Rate as of
such Trading Day; and 
 (iii) the shares of Common Stock the holder of such Note shall receive in respect of such Trading Day
are not entitled to participate in the distribution or transaction giving rise to such adjustment event because, pursuant to the terms of Section 15.02(k), such shares were not held by such holder on the record date corresponding to such
distribution or transaction, 
 then the Company will adjust the number of shares of Common Stock deliverable with respect to the Daily Settlement Amount for
such Trading Day to reflect the relevant distribution or transaction. 
 (q) If: 
 (i) the Company elects to satisfy the Conversion Obligation solely in shares of Common Stock; 
 (ii) any event that requires an adjustment to the Conversion Rate under any of clauses (a), (b), (c), (d) and (e) of this
Section 15.04 has not resulted in an adjustment to the Conversion Rate as of the Conversion Date; and 
 (iii) the shares
of Common Stock the holder of such Note shall receive on settlement are not entitled to participate in the distribution or transaction giving rise to such adjustment event because, pursuant to the terms of Section 15.02(k), such shares were not
held by such holder on the record date corresponding to such distribution or transaction, 
 then the Company will adjust the number of shares of Common
Stock deliverable with respect to the relevant Trading Day to reflect the relevant distribution or transaction. 
 (r) For purposes of this
Section 15.04, the number of shares of Common Stock at any time outstanding shall not include shares 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. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

 Section 15.05. Shares to Be Fully Paid. The Company shall provide, free from preemptive
rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion. 
 Section 15.06. Effect of Reclassification, Consolidation, Merger or Sale. Upon the occurrence of (i) any reclassification or change of
the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or combination covered by Section 15.04(a)), (ii) any
consolidation, merger or combination involving the Company, or (iii) any sale or conveyance of all or substantially all of the property and assets of the Company to any other Person, in each case as a result of which holders of Common Stock
shall be entitled to receive cash, securities or other property or assets with respect to or in exchange for such Common Stock (any such event a “Merger Event”), then: 
 (a) the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which
shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) permitted under Section 11.01(g) providing for the conversion and
settlement of the Notes as set forth in this Indenture. Such supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 15. If, in the case of any
Merger Event, the Reference Property includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger,
combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the holders of the Notes as the Board of Directors shall
reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the repurchase rights set forth in Article 16 herein. 
 In the event the Company shall execute a supplemental indenture pursuant to this Section 15.06, the Company shall promptly file with
the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect
thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Noteholders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Noteholder, at its
address appearing on the Note Register provided for in this Indenture, within twenty days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
 (b) Notwithstanding the provisions of Section 15.02(b), and subject to the provisions of Section 15.01 and Section 15.03,
at and after the effective time of such Merger Event, (i) the right to convert each $1,000 principal amount of Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock at the Company’s election as set
forth in Section 15.02 will be changed to a right to convert each $1,000 principal amount of such Note into cash, the kind and amount of shares of stock, 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 Conversion Rate immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”) or a combination of cash and Reference Property
at the Company’s election and (ii) the related Conversion Obligation shall be settled as set forth under clause (c) below, it being understood and agreed that for purposes of Section 15.01(b), references 

  

 -65- 








 
therein to “the Last Reported Sale Price of the Common Stock” shall be deemed at and after the effective time of such Merger Event to be references
to “the Last Reported Sale Price of a unit of Reference Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock
immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration” and references therein to “the Daily VWAP of the Common Stock” shall be deemed at and after the effective
time of such Merger Event to be references to “the Daily VWAP of a unit of Reference Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder
of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration.” The Company shall not become a party to any Merger Event unless its terms are
consistent with this Section 15.06. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set
forth in Section 15.01 and Section 15.02 prior to the effective date of such Merger Event. 
 (c) With respect to
each $1,000 principal amount of Notes surrendered for conversion after the effective date of any such Merger Event, the Company’s Conversion Obligation shall be settled in cash or units of Reference Property, at the Company’s election, in
accordance with Section 15.02(b) as follows: 
 (i) (A) if the Company elects to satisfy its Conversion Obligation
in respect of such conversion by delivering solely Reference Property, the Company shall deliver to the converting Noteholder a number of units of Reference Property (each such unit comprised of the kind and amount of shares of stock, securities or
other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration) equal to
(1) the aggregate principal amount of Notes to be converted, divided by $1,000, multiplied by (2) the then-applicable Conversion Rate; (B) if the Company elects to satisfy its Conversion Obligation in respect of such
conversion by paying solely cash, the Company shall pay to the converting Noteholder cash in an amount, per $1,000 principal amount of Notes equal to the sum of the Daily Conversion Values for each of the forty consecutive Trading Days during the
related Cash Settlement Averaging Period, such Daily Conversion Values determined as if the reference to “the Daily VWAP of the Common Stock” in definition thereof were instead a reference to “the Daily VWAP of a unit of Reference
Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or
been entitled to receive based on the Weighted Average Consideration”; and (C) if the Company elects to satisfy its Conversion Obligation through delivery of a combination of cash and Reference Property, the Company shall deliver 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 forty consecutive Trading Days during the Cash Settlement Averaging Period for such Note, such
Daily Settlement Amounts determined as if the reference to “the Daily VWAP of the Common Stock” in definition of Daily Conversion Value and Daily Share Amount were instead a reference to “the Daily VWAP of a unit of Reference Property
comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been
entitled to receive based on the Weighted Average Consideration.” 
  

 -66- 








 (ii) The Company will deliver the cash in lieu of fractional units of Reference Property
as set forth pursuant to Section 15.02(l) (provided that the amount of such cash shall be determined as if references in such Section to “the Daily VWAP of the Common Stock” were instead a reference to “the Daily VWAP of a
unit of Reference Property composed of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would
have owned or been entitled to receive based on the Weighted Average Consideration”). 
 (iii) The Daily Settlement
Amounts (if applicable) and Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Cash Settlement Averaging Period. 
 (iv) For purposes of this Section 15.06, the “Weighted Average Consideration” shall mean the weighted average of the
types and amounts of consideration received by the holders of the Common Stock entitled to receive cash, securities or other property or assets with respect to or in exchange for such Common Stock in any Merger Event who affirmatively make such an
election. 
 (v) The Company shall notify the holders of the Weighted Average Consideration as soon as practicable after the
Weighted Average Consideration is determined. 
 (d) The above provisions of this Section shall similarly apply to successive
Merger Events. 
 Section 15.07. Certain Covenants. 
 (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue
thereof. 
 (b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder
require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the
Commission, secure such registration or approval, as the case may be. 
 (c) The Company further covenants that if at any time the Common
Stock shall be listed on any national securities exchange or automated quotation system, the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable
upon conversion of the Notes. 
 Section 15.08. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not
at any time be under any duty or responsibility to any Noteholder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with
respect to the nature or extent or calculation of any such 

  

 -67- 








 
adjustment when made, or with respect to 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 securities, property or cash that may at any time be issued or delivered upon the
conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any 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 Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this
Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to
Section 15.06 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.06 or to any
adjustment to be made with respect thereto, but, subject to the provisions of Section 8.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible
for determining whether any event contemplated by Section 15.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices
referred to in Section 15.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the
Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 15.01(b). 
 Section 15.09. Notice to Noteholders Prior to Certain Actions. In case: 
 (a) the
Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 15.04; or 
 (b) the Company shall authorize the granting to all of the holders of its Common Stock of rights, options or warrants to subscribe for or
purchase any share of any class or any other rights, options or warrants; or 
 (c) of any reclassification of the Common
Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is
a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 
 (d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; 
 the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at its address appearing on the Note Register, provided for in Section 2.06
of this Indenture, as promptly as possible but in any event at least twenty days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such dividend, distribution
or rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (ii) the date on which such 

  

 -68- 








 
reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or
winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. 
 Section 15.10. Stockholder Rights Plans. To the extent that the Company has a stockholder rights plan or other “poison pill” in
effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such
conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan or poison pill, as the same may be amended from time to time. If, however, prior to the time of conversion, the rights have
separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that the holders of the Notes would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon
conversion of the Notes, the Conversion Rate will be adjusted at the time of separation as if the Company has distributed to all holders of Common Stock, shares of Capital Stock of the Company, evidence of indebtedness or assets as provided in
Section 15.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 
 Section 15.11. Exchange in Lieu of Conversion. When a holder surrenders its Notes for conversion, the Company may, at its election, direct the Conversion Agent to surrender, on or prior to the second Business Day following the
relevant Conversion Date, such Notes to a financial institution designated by the Company (the “Designated Institution”) for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion for exchange in
lieu of conversion, the Designated Institution must agree to timely deliver, in exchange for such Notes, the shares of Common stock and/or cash that would otherwise be due upon conversion pursuant to Section 15.02 and in respect of which the
Company has notified converting Noteholders. If the Company makes the election provided for in this Section 15.11, the Company shall, by the close of business on the second Business Day following the relevant Conversion Date as part of its
Settlement Notice, notify the holder surrendering its Notes for conversion that it has made such election. In addition, the Company shall concurrently notify the Designated Institution of the Settlement Method (and, if applicable, the Specified
Dollar Amount) that Company has elected with respect to such conversion and the relevant deadline for delivery of the consideration due upon conversion. Any Notes exchanged by the Designated Institution will remain outstanding. 
 If the Designated Institution agrees to accept any Notes for exchange but does not timely deliver the related consideration due upon conversion to the
Conversion Agent, or if the Designated Institution does not accept such Notes for exchange, the Company shall, within the time period specified in Section 15.02(e), convert such Notes into cash and/or shares of Common Stock, as applicable in
accordance with the provisions of Section 15.02. 
 For the avoidance of doubt, in no event will the Company’s designation of a
Designated Institution pursuant to this Section 15.11 require the Designated Institution to accept any Notes for exchange.

 REPURCHASE OF NOTES AT OPTION OF HOLDERS 
 Section 16.01. [Reserved] 
  

 -69- 








 Section 16.02. Repurchase at Option of Noteholders upon a Fundamental Change. (a) If
there shall occur a Fundamental Change at any time prior to the Maturity Date, then each Noteholder shall have the right, at such holder’s option, to require the Company to repurchase for cash all of such holder’s Notes, or any portion
thereof that is an integral multiple of $1,000 principal amount, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than twenty Business Days and not more than thirty-five Business Days
after the date of the Fundamental Change Company Notice (as defined below) at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, including unpaid Additional Interest, if any, thereon to, but
excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date is after an Interest Record Date and on or prior to the related Interest Payment Date, in
which case interest accrued to the Interest Payment Date will be paid to holders of the Notes as of the preceding Interest Record Date and the Fundamental Change Repurchase Price payable to the holder surrendering the Note for repurchase pursuant to
this Article 16 shall be equal to the principal amount of Notes subject to repurchase and will not include any accrued and unpaid interest, including Additional Interest, if any. Repurchases of Notes under this Section 16.02 shall be made, at
the option of the holder thereof, upon: 
 (i) delivery to the Paying Agent by a holder of a duly completed notice (the
“Fundamental Change Repurchase Notice”) in the form set forth on the reverse of the Note as Exhibit C thereto on or prior to the Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date; and 
 (ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time after delivery of the Fundamental Change Repurchase
Notice (together with all necessary endorsements) at the office of the Paying Agent, such delivery being a condition to receipt by the holder of the Fundamental Change Repurchase Price therefor; provided that such Fundamental Change
Repurchase Price shall be so paid pursuant to this Section 16.02 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Fundamental Change Repurchase Notice. 
 The Fundamental Change Repurchase Notice shall state: 
 (A) if certificated, the certificate numbers of Notes to be delivered for repurchase; 
 (B)
the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and 
 (C) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture; 
 provided,
however, that if the Notes are not in certificated form, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures. 
 Any repurchase by the Company contemplated pursuant to the provisions of this Section 16.02 shall be consummated by the payment of the Fundamental Change Repurchase Price pursuant to Section 16.04(a).

 Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent the Fundamental Change Repurchase Notice
contemplated by this Section 16.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Scheduled Trading Day immediately preceding the Fundamental
Change Repurchase Date in accordance with Section 16.03. 
  

 -70- 








 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change
Repurchase Notice or written notice of withdrawal thereof. 
 (b) On or before the twentieth calendar day after the occurrence of the
effective date of a Fundamental Change, the Company shall mail or cause to be mailed to all holders of record of the Notes a notice (the “Fundamental Change Company Notice”) of, and issue a press release in respect of, the
occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the holders arising as a result thereof. Such mailing shall be by first class mail. The Company shall also deliver a copy of the Fundamental
Change Company Notice to the Trustee, the Paying Agent and the Conversion Agent within five Business Days after the effective date of the Fundamental Change. Simultaneously with the providing of such notice, the Company will also publish a notice
containing the information set forth in the Fundamental Change Company Notice 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 that time. Each Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change;

 (ii) the effective date of the Fundamental Change, and whether the Fundamental Change is a Make-Whole Fundamental Change,
in which case the Effective Date of the Make-Whole Fundamental Change; 
 (iii) the last date on which a holder may exercise
the repurchase right pursuant to this Article 16; 
 (iv) the Fundamental Change Repurchase Price; 
 (v) the Fundamental Change Repurchase Date; 
 (vi) if applicable, the name and address of the Paying Agent and the Conversion Agent; 
 (vii) if applicable, the applicable Conversion Rate, and any adjustments to the applicable Conversion Rate; 
 (viii)
if applicable, that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a holder may be converted only if the holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this
Indenture; 
 (ix) that the holder must exercise the repurchase right on or prior to the close of business on the Scheduled
Trading Day immediately preceding the Fundamental Change Repurchase Date (the “Fundamental Change Expiration Time”); 
 (x) that the holder shall have the right to withdraw any Notes surrendered prior to the Fundamental Change Expiration Time; and 
  

 -71- 








 (xi) the procedures that holders must follow to require the Company to repurchase their
Notes. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights
or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 16.02. 
 (c) Notwithstanding the
foregoing, no Notes may be repurchased by the Company at the option of the holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental
Change Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). 
 (d) In connection with any purchase offer, the Company will: 
 (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act, if required under the
Exchange Act, 
 (ii) file a Schedule TO or any successor or similar schedule, if required under the Exchange Act, and

 (iii) otherwise comply with all federal and state securities laws in connection with any offer by the Company to purchase
the Notes. 
 Notwithstanding anything to the contrary provided in this Indenture, compliance by the Company with Rule 13e-4, Rule 14e-1 and
any other tender offer rule under the Exchange Act in accordance with clause (i) above, to the extent inconsistent with any other provision of this Indenture, will not, standing alone, constitute an Event of Default solely as a result of
compliance by the Company with such rules. 
 Notwithstanding the foregoing the Company shall not be required to repurchase the Notes in
accordance with this Section 16.02 if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 16.02 and purchases all Notes validly tendered and not withdrawn
under such purchase offer. 
 Section 16.03. Withdrawal of Fundamental Change Repurchase Notice. 
 (a) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Corporate Trust Office of the
Paying Agent in accordance with this Section 16.03 at any time prior to the close of business on the Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date, specifying: 
 (i) the certificate number, if any, of the Note in respect of which such notice of withdrawal is being submitted, or the appropriate
Depositary information if the Note in respect of which such notice of withdrawal is being submitted is represented by a Global Note, 
 (ii) the principal amount of the Note with respect to which such notice of withdrawal is being submitted, and 
  

 -72- 








 (iii) the principal amount, if any, of such Note that remains subject to the original
Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided,
however, that if the Notes are not in certificated form, the withdrawal notice must comply with appropriate procedures of the Depositary. 
 Section 16.04. Deposit of Fundamental Change Repurchase Price. 
 (a) The Company will deposit with the Trustee (or other
Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 5.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase
Date an amount of cash sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company),
payment for Notes surrendered for repurchase (and not withdrawn prior to the Fundamental Change Expiration Time) will be made on the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided the holder has
satisfied the conditions in Section 16.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the holder thereof in the manner required by
Section 16.02 by mailing checks for the amount payable to the holders of such Notes entitled thereto as they shall appear in the Note Register, provided, however, that payments to the Depositary shall be made by wire transfer of
immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

 (b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the
Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased as a result of the corresponding Fundamental Change, then (i) such Notes will cease to be outstanding, (ii) interest, including
Additional Interest, if any, will cease to accrue on such Notes, and (iii) all other rights of the holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price, and previously accrued but unpaid
interest, including Additional Interest, if any, upon delivery of the Notes), whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent. 
 (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 16.02, the Company shall execute and the Trustee shall
authenticate and deliver to the holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

sufficiently given if given to the Depositary for such Note (or its designee), pursuant to customary procedures of such Depositary.

the period from and after such date.

 Section 17.09. Table of Contents, Headings, Etc. The table of contents and the titles and headings of the articles and
sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof. 
 Section 17.10. Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its behalf and
subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Section 2.05, Section 2.06, Section 2.07,
Section 2.08, Section 11.04 and Section 16.04 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes. For all
purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the
Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee
hereunder pursuant to Section 8.09. 
  

 75 








 Any corporation or other entity into which any authenticating agent may be merged or converted or with

of any authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this Section, without the execution or filing of any paper or any further act on the
part of the parties hereto or the authenticating agent or such successor corporation or other entity. 
 Any authenticating agent may at any
time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the
Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be
the Trustee), shall give written notice of such appointment to the Company and shall mail notice of such appointment to all Noteholders as the names and addresses of such holders appear on the Note Register. 
 The Company agrees to pay to the authenticating agent from time to time reasonable compensation for its services although the Company may terminate the
authenticating agent, if it determines such agent’s fees to be unreasonable. 
 The provisions of Section 8.02, Section 8.03,
Section 8.04, Section 9.03 and this Section 17.10 shall be applicable to any authenticating agent. 
 If an authenticating
agent is appointed pursuant to this Section, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
  

			
	  
	 	,
	as Authenticating Agent, certifies that this is one of the Notes described in the within-named Indenture.

  

			
	By:	 	 
	Authorized Officer

 Section 17.11. Execution in Counterparts. This Indenture may be executed in any number
of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 
 Section 17.12. Severability. In the event any provision of this Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the
remaining provisions shall not in any way be affected or impaired. 
 Section 17.13. Waiver of Jury Trial. EACH OF THE COMPANY
AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

 Section 17.14. Force Majeure. In no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or
military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable
efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

 [FORM OF REVERSE OF NOTE] 
 ALLIANCE DATA SYSTEMS CORPORATION 
 4.75% Convertible Senior Note due 2014 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 4.75% Convertible Senior Notes due 2014 (the
“Notes”), limited to the aggregate principal amount of $300,000,000 (as increased by the aggregate principal amount of any additional Notes purchased by the Initial Purchasers pursuant to their option to purchase additional Notes
set forth in the Purchase Agreement) all issued or to be issued under and pursuant to an Indenture dated as of June 2, 2009 (as such may be amended from time to time, the “Indenture”), between the Company and The Bank of New
York Mellon Trust Company, National Association (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of and interest, including Additional
Interest, if any, on all Notes may be declared, by either the Trustee or the 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 and certain exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the
Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the holder who surrenders a Note to a Paying Agent to collect
such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 
 The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the holders of the Notes, and
in other circumstances, with the consent of the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of
the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the holders of
all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
 No reference herein to the Indenture
and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and accrued and unpaid interest, and Additional Interest, if any, on this Note at the
place, at the respective times, at the rate and in the lawful money herein prescribed. 
 The Notes are issuable in registered form without
coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be
exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any tax, assessments or other
governmental charges that may be imposed in connection therewith as a result of the name of the holder of the new Notes issued upon such exchange of Notes being different from the name of the holder of the old Notes surrendered for such exchange.

 The Notes are not subject to redemption through the operation of any sinking fund or otherwise.

 Upon the occurrence of a Fundamental Change, the holder has the right, at such holder’s option, to require the Company to repurchase
for cash all of such holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. 
 Subject to the provisions of the Indenture, the holder hereof has the right, at its option, during certain periods and upon the occurrence of certain
conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash,
shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at a Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
