authorized in writing. 
 No service charge shall be charged to the Noteholder for any exchange or registration of transfer of Notes, but the

otherwise required by law, all Notes shall be represented by 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

DATE OF ORIGINAL ISSUANCE OF NOTES (INCLUDING THROUGH THE EXERCISE BY GOLDMAN, SACHS & CO. OF ITS OPTION TO PURCHASE ADDITIONAL NOTES TO COVER OVERALLOTMENTS). THE RESTRICTIONS SET FORTH IN THIS LEGEND SHALL CEASE TO HAVE EFFECT ONE YEAR
AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF NOTES (INCLUDING THROUGH THE EXERCISE BY GOLDMAN, SACHS & CO. OF ITS OPTION TO PURCHASE ADDITIONAL NOTES TO COVER OVERALLOTMENTS) PROVIDED THAT ALL HOLDERS AFTER SUCH DATE SHALL CONTINUE TO BE
REQUIRED TO TRANSFER NOTES IN CONFORMITY WITH THE REQUIREMENTS OF APPLICABLE SECURITIES LAWS.

 No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note
Registrar unless the applicable box on the Form of Assignment and Transfer has been checked. 
 Any Note (or security issued in exchange or
substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.06, be
exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.06(d). The Company shall notify the Trustee upon the occurrence of the Resale Restriction
Termination Date and promptly after a registration statement with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act. 
 Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.06(d)), a Global Note may not be
transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner)
by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section. 
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Note. Initially, the Global Note
shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and
a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default in
respect of the Notes has occurred and is continuing, upon the request of the beneficial owner of the Notes, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and
delivery of Notes, will authenticate and deliver Notes in definitive form to each such beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for
such Global Note, and upon delivery of the Global Note to the Trustee such Global Note shall be canceled. 
 Definitive Notes issued in
exchange for all or a part of the Global Note pursuant to this Section 2.06(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such definitive Notes to the Persons in whose names such definitive Notes are so registered. 
 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 standing procedures and instructions existing between the Depositary and the Custodian. At any 

  

 -18- 








 
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, in accordance with the standing procedures and instructions existing
between the Depositary and the Custodian, 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. 
 None of the Company, the Trustee nor any agent of the Company or the Trustee will have any responsibility or liability for any
actions taken or not taken by the Depositary or any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. 
 (e)        Until the Resale Restriction Termination Date, any stock
certificate representing Common Stock issued upon conversion of such Note shall bear a legend in substantially the following form (unless the Note or such Common Stock has been transferred pursuant to a registration statement that has become or been
declared effective under the Securities Act and that continues to be effective at the time of such transfer or pursuant to the exemption from registration provided by Rule 144 under the Securities Act or any similar provision then in force under the
Securities Act, or such Common Stock has been issued upon conversion of Notes that have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at
the time of such transfer or pursuant to the exemption from registration provided by Rule 144 under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent for the Common
Stock): 
 THE SALE OF THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES 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 BY GOLDMAN, SACHS & CO. OF ITS OPTION TO PURCHASE ADDITIONAL NOTES TO COVER OVERALLOTMENTS) 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 ISSUER, OFFER, RESELL, PLEDGE OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY, EXCEPT (A) TO THE ISSUER; (B) UNDER A REGISTRATION STATEMENT THAT
HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT; (C) TO A PERSON THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT
OF ANOTHER QUALIFIED INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE); OR (D) UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF 

  

 -19- 








 
THE SECURITIES ACT; AND (2) AGREES THAT IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY PURSUANT TO CLAUSE (D) WITHIN THE LATER OF (X) SIX
MONTHS (OR, IF THE ISSUER 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 BY GOLDMAN, SACHS & CO. OF ITS OPTION TO
PURCHASE ADDITIONAL NOTES TO COVER OVERALLOTMENTS) 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 ISSUER, FURNISH TO THE
TRANSFER AGENT AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO SUCH OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT. IN ANY EVENT, NO AFFILIATE OF THE ISSUER MAY PURCHASE OR SELL THIS SECURITY. THE RESTRICTIONS SET FORTH IN THIS LEGEND SHALL CEASE TO HAVE EFFECT ONE YEAR AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF NOTES (INCLUDING THROUGH THE EXERCISE BY
GOLDMAN, SACHS & CO. OF ITS OPTION TO PURCHASE ADDITIONAL NOTES TO COVER OVERALLOTMENTS) UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED PROVIDED THAT ALL HOLDERS AFTER SUCH DATE SHALL CONTINUE TO BE REQUIRED TO TRANSFER NOTES IN
CONFORMITY WITH THE REQUIREMENTS OF APPLICABLE SECURITIES LAWS. 
 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). 
 (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 

  

 -20- 








 
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. 
 (h)        The Trustee shall have no obligation or duty to monitor, determine or inquire as to the compliance with any restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Note including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note other than to require by, and to do so if and when expressly required by
the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 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 

  

 -21- 








 
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. 
  

 -22- 








 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 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. 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. 
 Section 2.11.        Repurchases. The Company may from time to time repurchase the Notes in open market
purchases or negotiated transactions without prior notice to Noteholders.

 [INTENTIONALLY OMITTED] 
 ARTICLE 4 
 SATISFACTION AND DISCHARGE 
 Section 4.01.        Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore authenticated and delivered (other than (x) Notes which have 

  

 -23- 








 
been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.07 and (y) Notes for whose payment money has
theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 5.04(d)) have been delivered to the Trustee for cancellation; or
(ii) the Company has deposited with the Trustee or delivered to Noteholders, as applicable, after the Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or
cash and shares of Common Stock or Reference Property, if any (solely to satisfy the Company’s Conversion Obligation, if applicable), sufficient to pay all of the outstanding Notes and all other sums due payable under this Indenture by the
Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have
been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 8.06 shall survive. 
 ARTICLE 5 
 PARTICULAR COVENANTS OF THE COMPANY 
 Section 5.01.        Payment of Principal, Premium, Interest and Additional Interest. The Company
covenants and agrees that it will cause to be paid the principal of and premium, if any (including the Fundamental Change Repurchase Price), and accrued and unpaid interest and Additional Interest, if any, on each of the Notes at the places, at the
respective times and in the manner provided herein and in the Notes. Notwithstanding anything to the contrary contained in this Indenture, the Company may, to the extent it is required to do so by law, deduct or withhold income or other taxes

 Section 5.02.        Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan,
The City of New York, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion
Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office or the office or agency of the Trustee in the Borough of Manhattan, The City of New York. 
 The Company may also from
time to time designate co-registrars, one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 8.10, a Trustee, so that there shall at all times be a Trustee hereunder. 
 Section 5.04.        Provisions as to Paying Agent. If the Company shall appoint a Paying Agent other than
the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.04: 
 (i)        that it will hold all sums held by it as such agent for the payment of the principal
of and premium, if any, and accrued and unpaid interest and Additional Interest, if any, on the Notes in trust for the benefit of the holders of the Notes; 
 (ii)        that it will give the Trustee prompt notice of any failure by the Company to make any
payment of the principal of and premium, if any, and accrued and unpaid interest and Additional Interest, if any, on the Notes when the same shall be due and payable; and 
 (iii)        that at any time during the continuance of an Event of Default, upon request of the

 The Company shall, on or before each due date of the principal

Fundamental Change Repurchase Price), if any, or accrued and unpaid interest or Additional Interest, if any, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action, provided
that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date. 
 (b)        If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal of, premium (including the Fundamental Change Repurchase
Price), if any, accrued and unpaid interest and Additional Interest, if any, on the Notes, set aside, segregate and hold in trust for the benefit of the holders of the Notes a sum sufficient to pay such principal, premium (including the Fundamental

the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any Paying Agent hereunder as required by this Section 5.04, such
sums to be held by the Trustee upon the trusts herein contained, and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums.

  

 -25- 








 (d)        Any money deposited with the Trustee or any Paying
Agent, or then held by the Company, in trust for the payment of the principal of or premium (including the Fundamental Change Repurchase Price), if any, accrued and unpaid interest and Additional Interest, if any, on any Note and remaining unclaimed

Certificate, or (if then held by the Company) shall be discharged from such trust; and the holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment,
shall at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, New York,

Section 5.05.        Existence. Subject to Article 12, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence. 
 Section 5.06.        Rule 144A Information Requirement and Annual Reports. At any time the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as
any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and
shall, upon written request, provide to any holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issued upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under the Securities Act. The Company shall take such further action as any holder or beneficial owner of such Notes or such Common Stock
may reasonably request to the extent required from time to time to enable such holder or beneficial holder to sell such Notes or shares of Common Stock in accordance with Rule 144A under the Securities Act, as such rule may be amended from time to
time. 
 (b)        The Company shall send to the Trustee within fifteen days after the same is
required to be filed with the Commission, copies of the quarterly and annual reports and of the information, documents and other reports, if any, that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act), and the Company shall otherwise comply with the requirements of Trust Indenture Act Section 314(a). Any such report, information or document that
the Company files with the Commission through the Commission’s EDGAR database shall be deemed delivered to the Trustee for purposes of this Section 5.06(b) at the time of such filing through the EDGAR database; provided however,
that the Trustee shall have no obligation whatsoever to determine if such filing has taken place. 
 (c)        Delivery of the reports, information and documents described in clause (b) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not
constitute 

  

 -26- 








 
constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any
of its covenants hereunder (as to which the Trustee is entitled to conclusively rely exclusively on an Officers’ Certificate). 
 (d)        If, at any time during the six-month period beginning on, and including, the date which is six months after the last original date of issuance of the Notes and ending on the date which is
the one year anniversary of the last original date of issuance of the Notes, the Company fails to timely file any document or report that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act,
as applicable (other than current reports on Form 8-K), or the Notes are not otherwise freely tradable by holders other than the affiliates (as a result of restrictions pursuant to United States securities law or the terms of this Indenture or the
Notes), the Company shall pay a one time Additional Interest payment in respect of the Notes in the amount of 0.50% of the principal amount of Notes outstanding. The Company shall pay any Additional Interest pursuant to this Section 5.06(d) on
the next Interest Payment Date to the record holder. 
 (e)        Unless 
 (i)        the restrictive legend on the Notes has been removed, and 
 (ii)        the Notes are freely tradable pursuant to Rule 144 under the Securities Act without
volume restrictions by holders other than Affiliates of the Company (without restrictions pursuant to U.S. securities law or the terms of this Indenture or the Notes), 
 as of the 365th day after the last date of original issuance of the Notes offered hereby, the Company shall pay Additional Interest on the Notes at an annual rate equal to 0.50% of the aggregate principal amount of
the Notes. So long as a condition described in either (i) or (ii) of this Section 5.06(e) continues, the Company shall pay such Additional Interest on February 1 and August 1 of each year to the Person who is the holder of
record of the Securities on the immediately preceding January 15 and July 15. When such registration default ceases to continue, accrued and unpaid Additional Interest through the date of cessation shall be paid in Cash on the subsequent
Interest Payment Date to the record holder. 
 (f)        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 to, resell any of the Notes that constitute “restricted securities” under Rule 144 that have been reacquired by any of them. The Notes
shall be issued with a restricted CUSIP number. Until such time as the Company notifies the Trustee to remove the restricted legend from the Notes, 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 from the Notes, such legend will be deemed removed from any Global Notes and an unrestricted CUSIP number for the Notes will be deemed to be the CUSIP number for 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. 
  

 -27-

current a form as is reasonably practicable, all information as to the names and addresses of the Noteholders contained in the most recent list furnished to it as provided in Section 6.01 or maintained by the Trustee in its capacity as Note

 (b)        appoints a Custodian of the Company or any Subsidiary that is a Significant Subsidiary

 -30- 








 Section 7.03.        Extension Fee. Notwithstanding anything
in this Indenture or in the Notes to the contrary (including Section 5.06(d)), if the Company so elects, the sole remedy of Noteholders for an Event of Default relating to any obligation to file reports as described under Section 5.06 or
any obligations the Company is deemed to have pursuant to Section 314(a)(1) of the Trust Indenture Act shall, for the first 90 days after the occurrence of such an Event of Default, consist exclusively of the right to receive an extension fee
on the Notes equal to 0.25% of the principal amount of the Notes (the “Initial Extension Fee”) (such election, the “Initial Extension Right”). If the Company exercises the Initial Extension Right, the Initial
Extension Fee will be payable to all Noteholders of record on the Record Date specified by the Company in its notice that it is electing to use the Initial Extension Right (which will fall between the date of that notice and the date of the related
Event of Default). On the 91st day after such Event of Default (if such violation is not cured or waived prior to such 91st day), the Notes will be subject to acceleration as provided in Section 7.02; provided however that if the Company
so elects, the sole remedy of Noteholders will for the succeeding 90 days consist exclusively of the right to receive an additional extension fee on the Notes equal to 0.50% of the principal amount of the Notes (the “Additional Extension
Fee” and each of the Additional Extension Fee and the Initial Extension Fee, an “Extension Fee” ) (such election, the “Additional Extension Right”). On the 181st day after such Event of Default (if such
violation is not cured or waived prior to such 181st day), the Notes will be subject to acceleration as provided in Section 7.02. In the event the Company does not elect to pay the Initial Extension Fee or the Additional Extension Fee upon any
such Event of Default in accordance with this paragraph, the Notes will be subject to acceleration as provided in Section 7.02. 
 In order to exercise the Initial Extension Right and elect to pay the Initial Extension Fee as the
sole remedy during the first 90 days after the occurrence of any Event of Default relating to the failure to comply with the reporting obligations in accordance with the preceding paragraph, the Company must (i) notify all holders of Notes and
the Trustee and Paying Agent of such election in writing prior to the close of business on the date on which such Event of Default occurs and (ii) pay such Initial Extension Fee on or before the close of business on the date on which such Event
of Default occurs. In order to exercise the Additional Extension Right (following the exercise of the Initial Extension Right) and to pay the Additional Extension Fee as the sole remedy starting the 91st day after the occurrence of any Event of Default relating to the failure to comply with the reporting obligations in accordance with the preceding paragraph, the Company must
(i) notify all holders of Notes and the Trustee and Paying Agent in writing of such election prior to the close of business on the 89th day
after the occurrence of an Event of Default for which the Company has elected to exercise its extension right and (ii) pay such Additional Extension Fee on the Record Date specified in the notice that the Company is electing to use the
Additional Extension Right (which record date will fall between the date of that notice and such 91st day). If the Company fails to timely give either such notice or pay any Extension Fee after giving the applicable notice, the Notes will be
immediately subject to acceleration as provided in Section 7.02. 
 Section 7.04.        Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 7.01 shall have occurred, the Company shall, upon
demand of the Trustee, pay to it, for the benefit of the holders of the Notes, the whole amount then due and payable on the Notes for principal, premium, if any, and interest and Additional Interest, if any, with interest on any overdue principal,
premium, if any, 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 

  

 -31- 








 
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 premium, if any, 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 agents 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. 
 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. 
  

 -32- 








 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 any Extension Fee or Additional Interest, 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 premium, if any, and interest, including any Extension Fee or Additional Interest, with interest on the overdue principal and
premium, if any, 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 premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, 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 premium, if any, and accrued and unpaid interest; and 
 Fourth, to the payment of the remainder, if any, to the Company. 
  

 -33- 








 Section 7.06.        Proceedings by Noteholders. No holder
of any Note shall have any right by virtue of or by availing 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 such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore
provided, and unless also 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
and 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, and the Trustee for 60 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 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 60-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 (it being understood that
the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Noteholders), 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 and premium, if any (including the Fundamental Change Repurchase Price upon repurchase pursuant to Section 16.02), and
accrued and unpaid interest and any accrued and unpaid Extension Fee or Additional Interest, 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 last paragraph of
Section 2.07 and Section 7.03, all powers and remedies given by this Article 7 to the Trustee 

  

 -34- 








 
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 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 determined in accordance with Section 9.04 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 determined in accordance with Section 9.04 may on behalf of the holders of all of the Notes waive
any past Default or Event of Default or rescind a declaration of acceleration hereunder and its consequences except (i) a default in the payment of premium, accrued and unpaid interest or any accrued and unpaid Extension Fee or Additional
Interest, 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 so long as, in each case, (x) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (y) all existing Defaults and Events of Default (other than
as a result of (i) or (ii) above) that have become due solely by such declaration of acceleration, have been cured or waived. 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 90 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, or premium, if any, accrued
and unpaid interest or any accrued and unpaid Extension Fee or Additional Interest, 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. 

 

 -35- 








 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; 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 determined in accordance with Section 9.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, 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. 
 ARTICLE 8 
 CONCERNING THE TRUSTEE 
 Section 8.01.        Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or 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 and no implied covenants or obligations shall be read into this Indenture against the Trustee. 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 indemnity or security satisfactory to it 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 negligent action, its own 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 
  

 -36- 








 (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); 
 (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 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 determined as provided in Section 9.04 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;

 (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,

 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

Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture other than the Trustee’s certificate of authentication. 
 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

 -39- 








 
to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and to hold it
harmless against, any and all loss, claim, damage, liability or expense, including taxes (other than taxes based on the income of the Trustee), incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee and arising
out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending the Trustee against any claim (whether asserted by the Company, a Noteholder or any other Person) 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 obligations 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 survive the termination or defeasance of this Indenture and the resignation or removal of the Trustee. The Trustee shall notify the Company promptly of any claim of which a
Responsible Officer receives written notice for which it may seek indemnity. 
 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 the absence of 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
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 90 days or (b) 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. 
  

 -40- 








 Section 8.10.        Resignation or Removal of Trustee. 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 60 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, at the expense of the Company, 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, 
 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, at the expense of the Company, any court of
competent jurisdiction for an appointment of a successor trustee. 
  

 -41- 








 (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 the reasonable written 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. 
 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 

  

 -42- 








 
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. 
  

 -43- 








 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 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 

  

 -44- 








 
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, premium, if any, 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 actually 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. 
 Section 9.05.        Revocation of Consents; Future Noteholders Bound. At any time prior to (but not 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.

 (a)        To cure any ambiguity or correct any omission, manifest error, defect or inconsistency in this Indenture, so long as such action will not adversely affect the
interests of the Noteholders; 
 (b)        to provide for the assumption by a Successor Company of
the obligations of the Company under this Indenture pursuant to Article 12; 
 (c)        to add
guarantees with respect to the Notes; 
 (d)        to provide for a successor Trustee in accordance
with the terms of this Indenture or to otherwise comply with any requirement of this Indenture; 
 (e)        to provide for the conversion of the Notes into Reference Property, to the extent that the Company and the Trustee deem such amendment necessary or advisable in connection with the
conversion of the Notes into Reference Property; provided that no such amendment or supplement may impair the rights or interests of any Noteholder; 
 (f)        to increase the Conversion Rate; 
 (g)        to secure the Notes; 
 (h)        to add
to the covenants of the Company such further covenants, restrictions or conditions for the benefit of the Noteholders or surrender any right or power conferred upon the Company; 
 (i)        to provide for the conversion of Notes in accordance with the terms of this Indenture; 
 (j)        to make any change that does not adversely affect the rights of any Noteholder in any material
respect; provided that any amendment to conform the provisions of this Indenture and the Notes to the “Description of the Notes” section in the Offering Memorandum will not be deemed to be adverse to any Noteholder; 
  

 -48- 








 (k)        to comply with any requirements of the Commission in
connection with the qualification of this Indenture under the Trust Indenture Act; or 
 (l)        to appoint a successor trustee with respect to the Notes. 
 Upon the written
request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall
not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this Section 11.01 may be executed by the Company and the Trustee without the consent of
the holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 11.02. 
 Section 11.02.        Supplemental Indentures With Consent of Noteholders. With the consent (evidenced as provided in Article 9) of the holders of at least a majority in aggregate principal
amount of the Notes at the time outstanding (determined in accordance with Article 9 and including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), the Company, when authorized
by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the holders of the Notes or waiving any past default; provided, however, that no such
supplemental indenture shall: 
 (a)        reduce the amount of Notes whose holders must consent to
an amendment; 
 (b)        reduce the rate, or extend the stated time for payment, of interest on
any Note or reduce the amount, or extend the stated time for payment, of any Extension Fee; 
 (c)        reduce the principal of, or extend the Maturity Date of, any Note; 
 (d)        make any change that impairs or adversely affects the conversion rights of any Notes; 
 (e)        reduce the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse to the Noteholders the Company’s obligation to make such payments, whether through
an amendment or waiver of provisions in the covenants, definitions or otherwise; 
 (f)        change
the place or currency of payment of principal or interest or any Extension Fee in respect of any Note; 
 (g)        impair the right of any holder to receive payment of principal of and interest on such holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any
payment on or with respect to such holder’s Note; 
  

 -49- 








 (h)        adversely affect the ranking of the Notes as senior
unsecured Indebtedness of the Company; 
 (i)        make any change in this Article 11 that requires
each Noteholder’s consent or in the waiver provisions in Section 7.01 or Section 7.09; or 
 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. 
 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. 
  

 -50- 








 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 in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee
shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and 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 its properties and assets substantially as an entirety 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; 
 (b)        immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this Indenture; and 
  

 -51- 








 (c)        the Company and the Successor Company provide adequate
assurance, to the extent that the Successor Company is not the issuer of any part of the Reference Property, that the immediate resale of the Reference Property received upon conversion by holders that are not affiliates of the Company will not
require registration under the Securities Act. 
 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 the properties and assets of one or more Subsidiaries of the Company substantially as an entirety to another Person, which properties and assets, if held by the Company instead of such
Subsidiaries, would constitute the properties and assets of the Company substantially as an entirety on a consolidated basis, shall be deemed to be the transfer of the properties and assets of the Company substantially as an entirety 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 and premium, if any, accrued and unpaid interest and any accrued and unpaid Extension Fee or Additional Interest, 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 either in its own name or in the name of the Company 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 previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Notes that such Successor Company
thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under 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. No merger, consolidation, conveyance,
transfer or lease shall be effective 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.

 ARTICLE 13 
 IMMUNITY OF INCORPORATORS, STOCKHOLDERS, 
 OFFICERS AND DIRECTORS 
 Section 13.01.        Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the
principal of or premium, if any, or accrued and unpaid interest and any accrued and unpaid Extension Fee or Additional Interest, on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any Indebtedness represented thereby, shall be had against any incorporator, stockholder, employee,
agent, officer or director or Subsidiary, as such, past, present or future, of 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. Upon compliance with the provisions of this Article 15 and subject to the restrictions set forth in Section 15.01(c), 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 described in
Section 15.01(b) below, at any time prior to May 1, 2014 under the circumstances and during the periods set forth in Section 15.01(b) below, and (ii) irrespective of the conditions described in Section 15.01(b) below, on or
after May 1, 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 47.1342 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) 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 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 

  

 -53- 








 
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 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 the Common Stock any rights or warrants entitling them, for a period of not more than 60 days after the date of 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 of such distribution; or 
 (B)        distribute to all or substantially all holders of the Common Stock assets of the
Company (including cash), debt securities or certain rights to purchase securities of the Company, which distribution has a per share value (as determined by the Board of Directors) exceeding 15% of the Last Reported Sale Price of the Common Stock
on the Trading Day immediately preceding the declaration date for such distribution, 
 then, in each case, the Company shall notify all holders of the Notes
and the Trustee at least 45 Scheduled Trading Days prior to the Ex-Date for such distribution. Once the Company has given such notice, holders may surrender their Notes for conversion at any time until the earlier of (i) 5:00 p.m. (New York
City time) on the Business Day immediately preceding the Ex-Date for such distribution or (ii) the announcement by the Company that such distribution will not take place, even if the Notes are not otherwise convertible at such time. Holders may
not exercise the conversion right described in this Section 15.01(b)(ii) if they may participate (as a result of holding Notes, and at the same time as holders of Common Stock participate) in any of the transactions described in subparagraph
(A) or (B) as if such Noteholders held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount of Notes held by such holders divided by $1,000, without having to convert their Notes.

 Holders will also have the right to convert their Notes if the Company is a party to a combination, merger, recapitalization, reclassification, binding
share exchange or other similar transaction or sale or conveyance of all or substantially all of the property and assets of the Company, in each case pursuant to which the Common Stock would be converted into cash, securities and/or other property,
that does not also constitute a Fundamental Change. In such event, holders will have the right to convert their Notes at any time beginning on the earlier of (i) the date on which the Company notifies holders of such transaction and
(ii) the effective date of such transaction ending on the 35th Scheduled Trading Day following the effective date of such transaction. The Company will use its reasonable best efforts to notify holders and the Trustee at least 45 Scheduled
Trading Days prior to the anticipated effective date of any such transaction, and in any event will give such notice no later than the actual effective date of any such transaction. 
  

 -54- 








 (iii)        In the event of a Fundamental Change, the Company
shall notify the holders and the Trustee of the occurrence of such Fundamental Change no later than the date on which such event occurs or becomes effective (the “Fundamental Change Effective Date”). The Company shall issue a press
release on such date indicating the Fundamental Change Effective Date. A Noteholder may surrender Notes for conversion at any time from and after the Fundamental Change Effective Date until (i) the Fundamental Change Repurchase Date
corresponding to such Fundamental Change or (ii) if there is no such Fundamental Change Repurchase Date, 30 Scheduled Trading Days following the Fundamental Change Effective Date. 
 (iv)        Prior to the close of business on the Business Day immediately preceding May 1, 2014, the Notes
may be surrendered for conversion in any calendar quarter after the calendar quarter ending September 30, 2008, and only during such calendar quarter, if the Last Reported Sale Price of the Common Stock for 20 or more Trading Days in a period
of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter exceeds 130% of the then-applicable Conversion Price on the last day of such preceding calendar quarter. The Conversion Agent, on behalf of
the Company, shall determine at the beginning of each calendar quarter commencing after September 30, 2008 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Company and the
Trustee. 
 (c)        A Noteholder may not exercise its conversion right with respect to all or any
portion of a Note, if such conversion would cause such Noteholder to become a “beneficial owner” (within the meaning of either Article IX of the Company’s Amended and Restated Articles of Incorporation or Section 607.0901(1)(e)
of the Florida Business Corporation Act) of more than 9.9% of the Company’s outstanding voting stock. 
 Section 15.02.        Conversion Procedures. 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, a “Settlement Amount” equal to the sum of the Daily Settlement Amounts for each of the 40 VWAP Trading Days during the applicable Observation Period. 
 The Settlement Amount will be delivered in cash and shares of Common Stock to converting Noteholders on the third Trading Day following the final VWAP
Trading Day of the applicable Observation Period. The Company will also deliver to each converting Noteholder cash in lieu of fractional shares of Common Stock as set forth pursuant to clause (k) below. 
 The Daily Settlement Amounts and the Daily Conversion Values shall be determined by the Company promptly following the last day of the Observation
Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values 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 and the Daily Conversion Values 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. 
 (b)        [Reserved.] 
 (c)        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 

  

 -55- 








 
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(i) 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
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(i), (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(f). 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. 
 (d)        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 (c). Except as provided in Section 15.03(c), the Company shall pay and deliver, as the case may be, the cash and shares of Common Stock due in respect of it Conversion Obligation on the third scheduled Trading
Day immediately following the last VWAP Trading Day of the Observation Period. 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.

 (e)        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. 
 (f)        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. 
 (g)        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. 
  

 -56- 








 (h)        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. 
 (i)        Upon conversion, a
Noteholder shall not receive any additional cash payment for accrued and unpaid interest and any Extension Fee or Additional Interest, except as set forth below. The Company’s settlement of the Conversion Obligations as described above shall be
deemed to satisfy its obligation to pay the principal amount of the Note and accrued and unpaid interest and any Extension Fee or Additional Interest, to, but not including, the Conversion Date. As a result, accrued and unpaid interest and any
Extension Fee or Additional Interest, 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, Extension Fee and Additional Interest, if any, payable on such Notes on the corresponding Interest Payment
Date notwithstanding the conversion. 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, Extension Fee 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 described above, no payment or adjustment will be made for accrued and unpaid interest and Additional
Interest, if any, on converted Notes. 
 (j)        The Person in whose name the certificate for any
shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the close of business on the last VWAP Trading Day of the applicable Observation Period; provided however, if such last VWAP
Trading Day of the applicable Observation 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. 
 (k)        For each Note surrendered for conversion, 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 Observation 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 by multiplying the Daily VWAP of a full share of Common Stock on the last VWAP
Trading Day of the related Observation Period by the fractional amount and rounding the product to the nearest whole cent. The Company shall determine the number of 

  

 -57- 








 
fractional shares for which cash shall be delivered by aggregating (i) all Notes a holder surrenders for conversion and (ii) fractional shares
included in the Daily Settlement Amounts over the entire related Observation Period rather than delivering cash in lieu of fractional shares for (x) each individual Note of such holder surrendered for conversion or (y) each day of the
related Observation Period. 
 Section 15.03.        Increased Conversion Rate Applicable to
Certain Notes Surrendered in Connection with 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 date that a Fundamental Change becomes effective (the
“Effective Date”) until, and including, the Business Day immediately preceding the Fundamental Change Repurchase Date corresponding to such Fundamental Change, 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 Fundamental Change, the amount set forth in the following table that corresponds to the Make-Whole Reference Date
and the Stock Price for such Fundamental Change, all as determined by the Company:

 provided however, that: 
 (i)        if the actual Stock Price of such Fundamental Change is between two Stock Prices
listed in the table above under the column titled “Stock Price,” or if the actual Make-Whole Reference Date of such Fundamental Change is between two Make-Whole Reference Dates listed in the table above in the row immediately below the
title “Effective Date,” then the Make-Whole Conversion Rate Adjustment for such Fundamental Change shall be determined by the Company by linear interpolation between the Make-Whole Conversion Rate Adjustment set forth for such higher and
lower Stock Prices, or for such earlier and later Make-Whole Reference Date based on a 365 day year, as applicable; 
 (ii)        if the actual Stock Price of such Fundamental Change is greater than $150.00 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 Fundamental Change is less than $16.64 per share (subject to adjustment in the same manner as the Stock Price as 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 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 column 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, 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 60.0961 per $1,000 principal amount of Notes, subject
to adjustment in the same manner as the Conversion Rate pursuant to Section 15.04. 
 Nothing in this Section 15.03 shall prevent
an adjustment to the Conversion Rate pursuant to Section 15.04 in respect of a Fundamental Change. 
 (b)        As provided in Section 15.01(b)(iii), the Company shall issue a press release indicating the Fundamental Change Effective Date. If holders are entitled to a Make-Whole Conversion Rate
Adjustment, each such press release shall also state that in connection with such Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Notes and the amount by which the Conversion Rate has been so
increased (along with a description of how such increase shall is calculated and the time period during which Notes must be surrendered in order to be entitled to such increase). 
  

 -59- 








 (c)        The Company will settle conversions of Notes converted
in connection with a Fundamental Change as provided in Section 15.02(d); provided however that in connection with a Fundamental Change in which holders of Common Stock receive only cash consideration for their shares of Common Stock (in
a single per-share amount, other than with respect to appraisal and similar rights), the Company shall settle conversions by delivering, on the tenth Business Day after the Conversion Date, for each $1,000 principal amount of Notes, an amount of
cash equal to (i) the applicable Conversion Rate on the Conversion Date, increased by additional shares, if any, calculated as set forth in this Section 15.03, multiplied by (ii) the per-share amount of cash consideration paid in such
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 shares of Common Stock, or if the Company effects a share split or share combination of Common Stock, the Conversion Rate will be adjusted based on the following formula: 
 

 
 where 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect as of the close of business on the day immediately preceding the Ex-Date for such dividend or distribution or the effective date of such share split or share
combination, as the case may be;
			
	 CR1
	  	=	  	the Conversion Rate in effect as of the opening of business on the Ex-Date for such dividend or distribution or 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 Ex-Date for such dividend or distribution or the effective date of such share split or share combination, as the case
may be; and
			
	 OS1
	  	=	  	the number of shares of Common Stock that would be outstanding as of the opening of business on the Ex-Date for such dividend or distribution immediately after giving effect to 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 on (x) the Ex-Date for such dividend or other distribution or
(y) the date on which such share split or share combination becomes effective, as applicable. If any dividend or distribution described in this Section 15.04(a) is declared but not 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 

  

 -60- 








 
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)        In case the Company shall distribute to all or substantially all holders of its Common Stock any rights or warrants entitling them for a period of not more than 60 days after the date of
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 Ex-Date for such distribution, the Conversion Rate shall be increased based on the following formula: 
 

 
 where 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect as of the close of business on the day immediately preceding the Ex-Date for such distribution;
			
	 CR1
	  	=	  	the Conversion Rate in effect as of the opening of business on the Ex-Date for such distribution;
			
	 OS0
	  	=	  	the number of shares of the Common Stock outstanding immediately prior to the Ex-Date for such distribution;
			
	 X
	  	=	  	the total number of shares of the Common Stock issuable pursuant to such rights or warrants; and
			
	 Y
	  	=	  	the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Last Reported Sale Prices of the Common Stock for
the ten consecutive Trading Day period ending on and including the Trading Day immediately preceding the Ex-Date for such distribution.

 Such adjustment shall become effective on the Ex-Date for such distribution. The Company shall not issue any such
rights or warrants in respect of the Common Stock held in treasury by the Company. In determining whether any rights 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 the ten consecutive Trading Day period ending on and including the Trading Day immediately preceding the Ex-Date for such distribution, and in determining the aggregate price payable to exercise such
rights and warrants, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, with the value of such consideration, if other than cash, to be
determined by the Board of Directors or a committee thereof. If any right or warrant described in this Section 15.04(b) is not exercised or converted prior to the expiration of the exercisability or convertibility thereof, the Conversion Rate
shall be immediately readjusted to the Conversion Rate that would then be in effect if the right or warrant had not been issued. 
  

 -61- 








 (c)        In case 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) and 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, 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: 
 

 
 where 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect as of the close of business on the day immediately preceding the Ex-Date for such distribution;
			
	 CR1
	  	=	  	the Conversion Rate in effect as of the opening of business on the Ex-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-Date for such
distribution; and
			
	 FMV
	  	=	  	the fair market value (as determined by the Board of Directors or a committee thereof) of the shares of Capital Stock, evidences of Indebtedness, assets or property distributed with respect to
each outstanding share of the Common Stock on the Ex-Date for such distribution.

 Such adjustment shall become effective on the Ex- 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 provision shall be made so that each Noteholder shall have the right to receive on conversion in respect of each Note held by such Noteholder, in addition to the number of shares of Common Stock which such
holder is entitled to receive, the amount and kind of securities and assets such holder would have received had such holder already owned a number of shares of Common Stock equal to the Conversion Rate immediately prior to the Record Date for the
distribution of the securities or assets. 
 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 in effect immediately before 5:00 p.m., New York City time, on the effective date of the Spin-Off will be increased based on the following formula: 
 

 
 where 
  

 -62- 









					
	 CR0
	  	=	  	the Conversion Rate in effect immediately before 5:00 p.m., New York City time, on the effective date of the Spin-Off;
			
	 CR1
	  	=	  	the Conversion Rate in effect immediately after 5:00 p.m., New York City time, on the effective date of 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 ten
consecutive Trading Day period beginning on and including the Trading Day immediately following the effective date of the Spin-Off; and
			
	 MP0
	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period beginning on and including the Trading Day immediately following the effective date
of the Spin-Off.

 The adjustment to the Conversion Rate pursuant to the preceding paragraph of this
Section 15.04(c) shall become effective as of the close of business on the effective date of the Spin-Off. In respect of any conversion within the 10 consecutive Trading Days beginning on the Trading Day immediately following the effective date
of the Spin-Off, references in this Section 15.04(c) with respect to the Spin-Off to ten consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and
the Conversion Date in determining the applicable Conversion Rate. 
 Subject in all respect to Section 15.10, rights 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 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 or
warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights 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-Date with respect to new rights or warrants with such rights (and a termination or expiration of the
existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights 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 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 or warrants (assuming such 

  

 -63- 








 
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 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 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 evidences of Indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights 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 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-Date for such dividend or distribution shall be substituted as “the Ex-Date” and
“the Ex-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-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-Date for
such distribution” within the meaning of Section 15.04(b). 
 If any dividend or distribution described in this
Section 15.04(c) is declared but not paid or made, the Conversion Rate shall be immediately readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or announced. 
 In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(c). 
 (d)        If the Company pays any cash dividend or distribution to all or substantially all holders of the
Common Stock, the Conversion Rate shall be increased based on the following formula: 
 

 
 where 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect as of the close of business on the day immediately preceding the Ex-Date for such dividend or distribution;
			
	 CR’
	  	=	  	the Conversion Rate in effect as of the opening of business on the Ex-Date for such dividend or distribution;
			
	 SP0
	  	=	  	the average of the Last Reported Sale Prices of the Common Stock during the ten consecutive Trading Day period ending on and including the Trading Day immediately preceding the Ex-Date for such
dividend or distribution; and

  

 -64- 









					
			
	 C
	  	=	  	the amount in cash per share the Company distributes to holders of its Common Stock.

 Any adjustment made pursuant to this Section 15.04(d) shall become effective on the Ex-Date for such dividend
or distribution. If any such dividend or distribution described in this Section 15.04(d) is declared but not paid or made, the Conversion Rate shall be immediately readjusted to be the Conversion Rate that would then be in effect if such
dividend or distribution had not been declared. 
 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 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 beginning on and including the Trading Day immediately following the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be
increased based on the following formula: 
 

 
 where 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect as of the close of business on the Expiration Date;
			
	 CR1
	  	=	  	the Conversion Rate in effect as of the opening of business on the day immediately following the Expiration Date;
			
	 AC
	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors or a committee thereof) paid or payable for shares of Common Stock purchased in such tender
or exchange offer;
			
	 OS0
	  	=	  	the number of shares of Common Stock outstanding as of the close of business on the Expiration Date (prior to giving effect to such tender offer or exchange offer);
			
	 OS1
	  	=	  	the number of shares of Common Stock outstanding as of the opening of business on the day immediately following the Expiration Date (after giving effect to such tender offer or exchange offer);
and
			
	 SP1
	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the ten consecutive Trading Day period beginning on and including the Trading Day immediately following the Expiration Date.


 Such adjustment shall become effective as of the close of business on the Expiration Date. In respect of any
conversion within the ten consecutive Trading Days beginning on and including the expiration date of 

  

 -65- 








 
any tender or exchange offer, references in this Section 15.04(e) with respect to ten consecutive Trading Days shall be deemed replaced with such lesser
number of Trading Days as have elapsed between the Expiration Date of such tender or exchange offer and the Conversion Date in determining the applicable Conversion Rate. 
 If: 
 (1) any distribution or transaction described in Sections 15.04(a) through (e) has not yet
resulted in an adjustment to the Conversion Rate on a given Trading Day within the Observation Period applicable to Notes that Noteholders have converted; and 
 (2) the shares Noteholders will receive in respect of such Trading Day are not entitled to participate in the relevant distribution or transaction (because they were not held on a related Record Date or otherwise);

 then the Company shall adjust the number of shares that it will deliver to Noteholders in respect of the relevant Trading Day to reflect the relevant
distribution or transaction. 
 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-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 the close of business on the last VWAP Trading Day of a related Observation Period, 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. 
  

 -66- 








 (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 NASDAQ Global Select Market, 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. 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 this
Section 15.04(i), 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 15 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. The Company shall not take any action that would result in adjustment of the Conversion Rate (A) without complying with
Nasdaq Market Rule 4350 (which requires stockholder approval of certain issuances of stock), if applicable, or (B) 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.

 (j)        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 any Extension Fee or Additional Interest;
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 any of the transactions described in this Section 15.04 as if such Noteholders held a number of shares of Common Stock
equal to the applicable 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. 
 (k)        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. 
  

 -67- 








 (l)        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 (with such adjustments to be made on each day and for each adjustment event occurring during the applicable Observation Period),
(ii) such time as all adjustments that have not been made prior thereto would have the effect of adjusting the Conversion Rate by at least 1%. 
 (m)        Except as described in this Article 15, the Company shall not adjust the Conversion Rate. 
 (n)        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
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. 
 (o)        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 Fundamental Change described in clause (b) of the definition thereof,
(ii) 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)), (iii) any consolidation, binding share exchange, recapitalization, merger, combination or other similar event involving the Company, or (iv) any sale or conveyance of all or substantially all of the property and
assets of the Company to any other Person, in each case as a result of which holders of Common Stock would 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 

  

 -68- 








 
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 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)        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 as set forth in Section 15.02 will be changed to a right to convert such Note into cash and 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”) 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
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.” 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 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 in accordance with Section 15.02(b) as follows: 
 (i)        The Company will 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 40
consecutive Trading Days during the Observation Period for such Note, such Daily Settlement Amounts determined as if the reference to “the Daily 

  

 -69- 








 
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.” 
 (ii)        The Company will deliver the cash in lieu of fractional units of Reference Property as set forth pursuant to Section 15.02(k) (provided that the amount of such cash shall be
determined as if references in such Section to “the Last Reported Sale Price of the Common Stock” were instead a reference to “the Last Reported Sale Price 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 Observation 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;
provided that, if the types and amounts of consideration that holders of the Common Stock would be entitled to receive with respect to or in exchange for such Common Stock is based in part upon any form of stockholder election, the
“Weighted Average Consideration” will be deemed to be (A) if holders of the majority of the shares of Common Stock affirmatively make such an election, the weighted average of the types and amounts of consideration received by the
holders of the Common Stock that affirmatively make such an election or (B) if the holders of a majority of the shares of Common Stock do not affirmatively make such an election, the types and amount of consideration actually received by such
holders. 
 (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. 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. 
  


 -70- 








 (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 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
conclusively 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 
  

 -71- 








 (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 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
Noteholder will receive, in addition to any Common Stock and in lieu of any adjustment to the Conversion Rate, the rights under the rights plan, unless prior to any conversion, the rights have separated from the Common Stock, in which case 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, evidences 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. Any distribution of rights or warrants pursuant to a rights plan that would allow a holder to receive upon conversion, in addition to any shares of the Common Stock, the
rights described therein with respect to such Common Stock (unless such rights or warrants have separated from the Common Stock) shall not constitute a distribution of rights or warrants that would entitle a holder to an adjustment to the Conversion
Rate. 
 ARTICLE 16 
 REPURCHASE OF
NOTES AT OPTION OF HOLDERS 
 Section 16.01.        [Reserved] 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 fifteen days and not
more than 35 days after the date of the Fundamental Change Repurchase Right Notice (as defined below) at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, including any Extension Fee or
Additional Interest, if any, thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), 

  

 -72- 








 
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. 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 Business 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 Corporate Trust Office of the Paying Agent in The Borough of Manhattan, 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 on the later of the Fundamental Change Repurchase Date and the time of the book-entry
transfer or delivery of the Note as described in 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 Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 16.03 below. 
 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. 
  

 -73- 








 (b)        On or before the tenth 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, the Trustee and the Paying Agent a notice (the “Fundamental Change Repurchase Right Notice”) 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. Simultaneously with the providing of such notice, the Company
will also publish a notice containing the information set forth in the Fundamental Change Repurchase Right 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 Repurchase Right Notice shall specify: 
 (i)        the events causing the Fundamental Change; 
 (ii)        the date of the Fundamental Change; 
 (iii)        the last date on which a holder may exercise the repurchase right pursuant to this Article 16, if applicable; 
 (iv)        the Fundamental Change Repurchase Price, if applicable; 
 (v)        the Fundamental Change Repurchase Date, if applicable; 
 (vi)        the name and address of the Paying Agent and the Conversion Agent, if applicable;

 (vii)        the applicable Conversion Rate, and any adjustments to the applicable
Conversion Rate, including any additional shares, if applicable; 
 (viii)        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
shall have the right to withdraw any Notes surrendered prior to the Business Day prior to the Fundamental Change Repurchase Date. 
 (x)        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). 
  

 -74- 








 (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. 
 (e)        the Company will not be required to make a
purchase offer if a third party makes such a purchase offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a purchase offer made by the Company, and purchases all Notes validly
tendered and not withdrawn under such purchase offer. 
 Section 16.03.        Withdrawal of
Fundamental Change Repurchase Notice. A Fundamental Change Repurchase Notice may be withdrawn in whole or in part by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this
Section 16.03 at any time prior to the Business Day prior to the Fundamental Change Repurchase Date, specifying: 
 (i)        the certificate number, if any, of the Notes in respect of which such notice of withdrawal is being submitted, or the appropriate Depositary information if the Notes in respect of which
such notice of withdrawal is being submitted are represented by a Global Note, 
 (ii)        the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, and 
 (iii)        the principal amount, if any, of such Notes that remain 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. 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 money 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 in accordance with this Indenture. 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. 
  

 -75- 








 (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 any Extension Fee or Additional Interest, 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 any Extension Fee or Additional Interest, 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.

 Section 17.07.        No Security Interest Created. Nothing in this Indenture or in the Notes, expressed or implied, shall be construed to constitute a security interest under the Uniform
Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any jurisdiction. 
 Section 17.08.        Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any
Conversion Agent, any authenticating agent, any Note Registrar and their successors hereunder or the Noteholders, any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 Section 17.09.        Table of Contents, Headings, Etc. The table of contents and the titles and headings of

 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. 
 Any corporation or other entity into which any authenticating
agent may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity
succeeding to all or substantially all the corporate trust business 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.

the following form:

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

 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
