SECURITIES LAWS. NEITHER THIS SECURITY, THE SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN OR THEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF
SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION. THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF, (1) AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE EXPIRATION OF THE
HOLDING PERIOD APPLICABLE TO SALES OF THIS SECURITY UNDER RULE 144(k) OF THE SECURITIES ACT (SUCH EXPIRATION DATE, THE “RESALE RESTRICTION TERMINATION DATE”) ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS

 11 








 
FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE
SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN
DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE RIGHTS OF THE COMPANY AND THE TRUSTEE PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER
PURSUANT TO CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES WHERE REGISTRATION OR TRANSFER OF THIS SECURITY IS REQUIRED, A
CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS SECURITY COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE AND (2) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY
TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED AFTER THE RESALE RESTRICTION TERMINATION DATE. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING
RESTRICTION. 
 (b) Restricted Securities Legend for the Common Stock Issued Upon Conversion of the Notes. 
 Each stock certificate representing Common Stock issued upon conversion of Notes bearing a Restricted Securities Legend will, subject to the availability

 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, 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 RESELL 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 ADOPTED UNDER THE SECURITIES ACT) THAT IS

ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF 

  

 12 








 
THE SECURITIES ACT; AND (2) IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY 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 AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 (c) Removal of the Restricted Securities Legends. 
 The Restricted Securities Legend may be removed from any Note or any Common Stock certificate representing shares of the Common Stock issued upon conversion of any Note if there is delivered to the Company such
satisfactory evidence, which may include an opinion of independent counsel, as may be reasonably required by the Company, that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers of such Note
or shares of the Common Stock issued upon conversion of Notes, as the case may be, will not violate the registration requirements of the Securities Act or the qualification requirements under any state securities laws. Upon provision of such
satisfactory evidence and receipt by the Trustee of a Company Order, (x) in the case of a Note, the Trustee shall authenticate and deliver in exchange for such Note another Note or Notes having an equal aggregate principal amount that does not
bear such legend or (y) in the case of a Common Stock certificate representing shares of the Common Stock, the transfer agent for the Common Stock shall authenticate and deliver in exchange for the Common Stock certificate or certificates
representing such shares of Common Stock bearing such legend, one or more new Common Stock certificates representing a like aggregate number of shares of Common Stock that do not bear such legend. If the Restricted Securities Legend has been removed
from a Note or Common Stock certificates representing shares of the Common Stock issued upon conversion of any Note as provided above, no other Note issued in exchange for all or any part of such Note, or no other Common Stock certificates issued in
exchange for such Common Stock, shall bear such legend, unless the Company has reasonable cause to believe that such other Note is a “restricted security” (or such shares of Common Stock are “restricted securities”) within the
meaning of Rule 144 and instructs the Trustee in writing to cause a Restricted Securities Legend to appear thereon. 
 Any Note (or Note
issued in exchange or substitution therefor) as to which the conditions for removal of the Restricted Securities Legend set forth in Section 2.03(a) as set forth therein have been satisfied may, upon surrender of such Note for exchange to the
Note Registrar in accordance with the provisions of Section 2.07, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restricted Securities Legend required by Section 2.03(a).

 Any Common Stock certificate representing shares of Common Stock issued upon conversion of any Note as to which the conditions for removal
of the Restricted Securities Legend set forth in Section 2.03(b) have been satisfied may, upon surrender of the Common Stock 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 Common Stock certificate or certificates representing a like aggregate number of shares of Common Stock, which shall not bear the Restricted Securities Legend. 
  

 13

NEW YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND
ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED
OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO IN THE

WILL HOLD NO NOTES. 
 Section 2.04. Date and Denomination of Notes; Payments on the Notes. 
 The Notes shall be issuable initially in fully registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof.
Each Note shall be dated the date of its authentication and shall bear interest from the date specified on the face of the form of Note attached as Exhibit A hereto, as applicable. Interest on the Notes (including any Additional Interest)

 If any Interest Payment Date (other than an
Interest Payment Date coinciding with the Maturity Date or required Fundamental Change Purchase Date) of a Note falls on a day that is not a Business Day, such Interest Payment Date will be postponed to the next succeeding Business Day. If the
Maturity Date or required Fundamental Change Purchase Date would fall on a day that is not a Business Day, the required payment of interest (including any Additional 

  

 14 








 
Interest), if any, and principal, will be made on the next succeeding Business Day and no interest on such payment will accrue for the period from and after
the Maturity Date or required Fundamental Change Purchase Date to such next succeeding Business Day.

or less, by check mailed to the holders of these Notes or (y) to holders having an aggregate principal amount of more than $5,000,000, either by check mailed to each holder or, upon application by a holder to the Note Registrar not later than
the relevant record date, by wire transfer in immediately available funds to that holder’s account within the United States, which application shall remain in effect until the holder notifies, in writing, the Note Registrar to the contrary. The
term “record date” with respect to any Interest Payment Date shall mean the June 1 or December 1 preceding the applicable June 15 or December 15 Interest Payment Date, respectively. 
 Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Noteholder on the relevant record date by virtue of his having been such Noteholder, and such Defaulted Interest shall be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below: 
 (i) The Company may elect to make payment of any Defaulted Interest
to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company
shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall be not less than twenty-five (25) days after the receipt by the Trustee of such notice,
unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the
Company shall fix a special record date for the payment of such Defaulted Interest which shall be not more than fifteen (15) days and not less than ten (10) days prior to the date of the proposed payment, and not less than ten
(10) days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee in writing of such special record date and the Trustee, in the name and at the expense of the Company, shall cause
notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first-class postage prepaid, to each holder at his address as it appears in the Note Register, not less than ten 

  

 15 








 
(10) days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so
mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the
following clause (2) of this Section 2.04. 
 (ii) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated
quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Section 2.05. Execution, Authentication and Delivery of Notes. 
 The Notes shall be signed in the
name and on behalf of the Company by the manual or facsimile signature of its Chairman or Vice-Chairman of the Board of Directors, Chief Executive Officer, President or any of its Vice Presidents.

Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes, without any further action by the Company
hereunder. 
 Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note
attached as Exhibit A hereto, executed manually or by facsimile by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 15.10), shall be entitled to the benefits of this Indenture or be valid or
obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and
that the holder is entitled to the benefits of this Indenture. 
 In case any officer of the Company who shall have signed any of the Notes
shall cease to be such officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who
signed such Notes had not ceased to be such officer of the Company and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the
date of the execution of this Indenture any such person was not such an officer. 
 The Trustee shall have the right to decline to
authenticate and deliver any Notes under this Section if the Trustee, being advised by counsel of national reputation, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would
expose the Trustee to personal liability to existing Noteholders.

provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby appointed “Note
Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-registrars in accordance with Section 3.03.

the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Noteholder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 
 All Notes presented or surrendered for registration of transfer or for exchange, purchase or conversion shall (if so required by the Company, the
Trustee, the Note Registrar or any co-registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Noteholder thereof or his attorney-in-fact duly
authorized in writing. 
 No service charge shall be charged to the Noteholder for any exchange or registration of transfer of Notes, but the

 All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture
shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. 
 (b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless 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 interests in a Global Note, which does not involve the
issuance of a Definitive Note, shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

 (c) Any Global Note shall initially bear (i) the Restricted Securities Legend set forth in Section 2.03(a) and (ii) the
Global Note Legend set forth in Section 2.03(d), and may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Indenture as may be required by the Custodian,
the Depositary or by the National Association of Securities Dealers, Inc. to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes
may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject. 
 Notwithstanding any other provisions of this Indenture, a Global Note may not be transferred as a whole or in part except 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. 
 (d) 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 each Global Note. Initially, each 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 at any time the Depositary for a Global Note (i) notifies the Company that it is unwilling or unable to
continue as Depositary for such Note or (ii) ceases to be registered as a clearing agency under the Exchange Act, the Company may appoint a successor Depositary with respect to such Note. If (1) a successor Depositary for such Global Note
is not appointed by the Company within ninety (90) days after the Company receives such notice or the Depositary ceasing to be a registered clearing agency, or (2) an Event of Default has occurred and is continuing and the Note Registrar
has received a request from the beneficial owner of a Note for the issuance of Notes in definitive form (“Definitive Notes”) in exchange for a Global Note, the Company will execute, and the Trustee, upon receipt of an Officer’s
Certificate for the authentication and delivery of Definitive Notes, will authenticate and deliver Definitive Notes 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. 
  

 18 








 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, purchased 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 time prior to such cancellation, if any interest in a Global Note is exchanged for Definitive Notes, converted, canceled, purchased 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. 
 Section 2.07. Special Transfer Provisions. 
 Unless a Note is no longer required to bear a Restricted Security Legend, the following provisions shall apply to any sale, pledge or other transfer of such Notes: 
 (a) Transfer of Notes to a QIB. 
 The
following provisions shall apply with respect to the registration of any proposed transfer of Notes to a QIB: 
 (i) If the
Notes to be transferred consist of a beneficial interest in the Global Notes, the transfer of such interest may be effected only through the book-entry systems maintained by The Depositary Trust Company. 
 (ii) If the Notes to be transferred consist of Definitive Notes, the Note Registrar shall register the transfer if such transfer is being
made by a proposed transferor who has checked the box provided for on the form of Note stating (or has otherwise advised the Company and the Registrar in writing) that the sale has been made in compliance with the provisions of Rule 144A to a
transferee who has signed a certification stating or has otherwise advised the Company and the Note Registrar in writing that: 
 (A) it is
purchasing the Notes for its own account or an account with respect to which it exercises sole investment discretion; 
 (B) it and any such
account is a QIB within the meaning of Rule 144A; 
  

 19 








 (C) it is aware that the sale to it is being made in reliance on Rule 144A; 
 (D) it acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to
request such information; and 
 (E) it is aware that the transferor is relying upon its foregoing representations in order to claim the
exemption from registration provided by Rule 144A. 
 (b) General. 
 By its acceptance of any Note bearing the Restricted Securities Legend, each holder of such Note acknowledges the restrictions on transfer of such Note
set forth in this Indenture and agrees that it will transfer such Note only as provided in this Indenture. The Note Registrar shall not register a transfer of any Note unless such transfer complies with the restrictions on transfer of such Note set
forth in this Indenture. The Note Registrar shall be entitled to receive and rely on written instructions from the Company verifying that such transfer complies with such restrictions on transfer. In connection with any transfer of Notes (other than
a transfer to the Company (or a Subsidiary of the Company) or a transfer pursuant to Rule 144A or pursuant to a registration statement declared effective under the Securities Act), each holder agrees by its acceptance of the Notes to furnish the
Note Registrar or the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the
registration requirements of the Securities Act; provided that the Note Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal
opinions or other information. 
 The Note Registrar shall retain copies of all certifications, letters, notices and other written
communications received pursuant to Section 2.06 hereof or this Section 2.07. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Note Registrar. 
 Section 2.08. 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. 
  

 20 








 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 substituted 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 which has matured or is about to mature or has been surrendered for
purchase upon a Fundamental Change or is about to be converted into Common Stock 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, 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 2.08 by virtue of the fact that any Note is destroyed, lost or stolen shall
constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in)
this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to
the replacement or payment or conversion or purchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect
to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 
 Section 2.09. 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 3.02 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. 

  

 21 








 
Until so exchanged, such 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 2.10. Restriction on Resale. 
 Any Notes or shares of Common Stock issued upon the conversion of Notes that are 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 shares of Common Stock, as
the case may be, no longer being “restricted securities” (as defined under Rule 144). 
 Section 2.11. Cancellation of Notes Paid, Etc.

 All Notes surrendered for the purpose of payment, purchase, 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 destroy canceled Notes in accordance with its customary procedures and, after such destruction, shall, at the Company’s written request, deliver a
certificate of such destruction to the Company. 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 2.12. 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 Fundamental Change Company Notices as a convenience to
holders of the Notes; 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 Fundamental Change Company 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 2.13. Additional Notes, Purchases. 
 The Company may, without the consent of the Noteholders and notwithstanding
Section 2.01 and issue additional Notes hereunder with the same terms and with the same CUSIP number as such Notes initially issued hereunder in an unlimited aggregate principal amount, which will form the same series with the Notes initially
issued hereunder so long as such additional Notes are fungible with such Notes initially issued hereunder for U.S. federal income tax purposes. The Company may also from time to time purchase Notes in tender offers, open market purchases or
negotiated transactions without prior notice to Noteholders. 
  

 22 








 Article 3 
 PARTICULAR COVENANTS OF THE COMPANY 
 Section 3.01. Payment of Principal and Interest. 
 The Company covenants and agrees that it will cause to be paid the

herein and in the Notes. 
 Section 3.02. Additional Interest. 
 If Additional Interest is payable by the Company, the Company shall deliver to the Trustee an Officer’s Certificate to that effect stating (i) the amount of such Additional Interest that is payable and
(ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer receives such a certificate, the Trustee may assume without inquiry that no Additional Interest is payable. If the Company has paid Additional
Interest directly to the persons entitled to it, the Company shall deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment. 
 Section 3.03. Maintenance of Office or Agency. 
 The Company will maintain an office or agency
where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment, redemptions or purchase (“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 not designated or appointed
by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office or the office or agency of the Trustee. 
 The Company may also from time to time designate 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 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. 
 The Company hereby initially designates the
Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office and the office or agency of the Trustee in New York, New York shall be considered as one such office or agency of the Company for each of the

in Section 6.10(a) and the third paragraph of Section 6.11. 
  

 23

 The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 6.10, a Trustee,
so that there shall at all times be a Trustee hereunder. 
 Section 3.05. Provisions as to Paying Agent.

 (i) that it will hold all sums held by it as such agent for the payment of the principal of, accrued and unpaid interest (including any
Additional Interest) on the Notes (whether such sums have been paid to it by the Company or by any other obligor on the Notes) in trust for the benefit of the holders of the Notes; 
 (ii) that it will give the Trustee notice of any failure by the Company (or by any other obligor on the Notes) to make any payment of the
principal of, accrued and unpaid interest (including any Additional Interest) on the Notes when the same shall be due and payable; and

 The Company shall, on or before each due date of the principal of, accrued and unpaid interest (including any Additional Interest) on the Notes, deposit
with the Paying Agent a sum sufficient to pay such principal or accrued and unpaid interest and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing 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, accrued and unpaid interest (including any Additional Interest) 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, accrued and unpaid interest so becoming due and will notify the Trustee in writing of any failure to take such action and of any failure by the Company (or any other obligor
under the Notes) to make any payment of the principal of, accrued and unpaid interest on the Notes, when the same shall become due and payable. 
 (c) Anything in this Section 3.05 to the contrary notwithstanding, the Company may, at any time, for 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, the Company or such Paying Agent shall be released from all further liability with respect to such sums. 
  

 24 








 (d) Anything in this Section 3.05 to the contrary notwithstanding, the agreement to hold sums in
trust as provided in this Section 3.05 is subject to Section 11.03 and Section 11.04. 
 Section 3.06. 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 3.07. 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 which would prohibit or forgive the Company from paying all or any portion of the principal of, accrued and unpaid interest (including any Additional Interest) on the Notes as contemplated herein, wherever enacted, now or at any
time hereafter in force, or which 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. 
 Section 3.08. Compliance Certificate; Statements as to Defaults. 
 The Company shall deliver to the Trustee within one hundred-twenty (120) calendar days after the end of each fiscal year of the Company (beginning with the fiscal year ending on or around March 30, 2008) an
Officer’s Certificate stating whether or not the signer thereof has knowledge of any failure by the Company to comply with all conditions and covenants then required to be performed under this Indenture and, if so, specifying each such failure
and the nature thereof. 
 In addition, the Company shall deliver to the Trustee, as soon as possible and in any event within thirty

take with respect thereto. 
  

 25 








 Section 3.09. Further Instruments and Acts. 
 Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or

the Trustee may reasonably request in order to enable it to timely provide any notice to be provided by it hereunder), a list in such form as the Trustee may reasonably require of the names and addresses of the Noteholders as of a date not more than
fifteen (15) days (or such other date as the Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no such list need be furnished so long as the Trustee is acting as
Note Registrar. 
 Section 4.02. Preservation and Disclosure of Lists. 
 (a) The Trustee shall preserve, in as 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 4.01 or maintained by the Trustee in its capacity as Note Registrar, if so acting. The Trustee may destroy any list furnished to it as provided in Section 4.01 upon
receipt of a new list so furnished. 
 (b) The rights of Noteholders to communicate with other Noteholders with respect to their rights under
this Indenture or under such Notes and the corresponding rights and duties of the Trustee, shall be as provided by the Trust Indenture Act. 
 (c) Every Noteholder, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of information
as to names and addresses of Noteholders made pursuant to the Trust Indenture Act. 
  

 26 








 Section 4.03. Reports by Trustee. 
 (a) The Trustee shall transmit to Noteholders such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to the

 (j) the Company or any of its Significant Subsidiaries

the same shall become and shall be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 5.01(j) or Section 5.01(k) occurs and is
continuing, the principal of all the Notes and accrued and unpaid interest and Additional Interest, if any, shall be immediately due and payable. This provision, however, is subject to the conditions that if, at any time after the principal of the
Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay installments of accrued and unpaid interest and Additional Interest, if any, upon all Notes and the principal of any and all Notes that shall have become due other than by acceleration (with interest on overdue installments of
accrued and unpaid interest and Additional Interest, if any (to the extent that payment of such interest is enforceable under applicable law) on such principal at the rate borne by the Notes during the period of such Default) and amounts due to the
Trustee pursuant to Section 6.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction 

  

 29 








 
and (2) any and all Events of Defaults under this Indenture, other than the nonpayment of principal of and accrued and unpaid interest and Additional
Interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 5.07, then and in every such case the holders of a majority in aggregate principal amount of the Notes then
outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right
consequent thereon. 
 Notwithstanding the foregoing, the sole remedy for an Event of Default relating to the failure to comply with
Section 4.04(a) hereof or Section 314(a)(1) of the Trust Indenture Act (a “Reporting Default”), will for the three hundred sixty-five (365) days after the occurrence of such Reporting Default consist exclusively of
the right to receive Additional Interest on the Notes as set forth in this paragraph. Commencing on (and including) any date that a Reporting Default first occurs (excluding any grace period) and ending on (but excluding) the 365th day thereafter
(or such earlier date on which the Reporting Default shall have been cured or waived) (the “Reporting Default Period”), the Company shall pay to the holders in respect of each day in the Reporting Default Period, Additional Interest
in respect of any outstanding Note, at a rate per annum equal to 0.50% of the aggregate principal amount of such Note. On such 365th day (or earlier, if the Reporting Default is cured or waived prior to such 365th day), such Additional Interest will
cease to accrue and the Notes will be subject to acceleration as provided above if the Reporting Default is continuing. The rate of accrual of the Additional Interest with respect to any Reporting Default Period shall not exceed the rate provided
for in this paragraph notwithstanding the occurrence of multiple concurrent Reporting Defaults. Such Additional Interest shall accrue from the first day of the applicable Reporting Default Period, and shall be payable on each Interest Payment Date
during the Reporting Default Period (and on the Interest Payment Date next succeeding the end of the Reporting Default Period if the Reporting Default Period does not end on an Interest Payment Date) to the holders of Notes entitled thereto;
provided that any Additional Interest accrued with respect to any Note or portion thereof purchased by the Company in accordance with Article 14 hereof or converted into Common Stock in accordance with Article 13 hereof prior to the Interest Payment
Date, shall, in any such event, be paid instead to the holder who submitted such Note or portion thereof for purchase or conversion on the applicable Fundamental Change Purchase Date or Conversion Date, as the case may be, on such date (or in the
case of conversion, promptly following the Conversion Date), unless the Fundamental Change Purchase Date or the Conversion Date, as the case may be, falls after the Record Date immediately preceding the Interest Payment Date and on or prior to the
corresponding Interest Payment Date. Any Additional Interest will be in addition to any Additional Interest that may accrue pursuant to Section 2 of the Registration Rights Agreement. The foregoing provisions in this Section 5.01 will not
affect the rights of Noteholders in the event of the occurrence of any other Event of Default and will not affect the rights of holders of Notes under the Registration Rights Agreement. 
 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 

  

 30 








 
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 5.02. Payments of Notes on Default; Suit Therefor. 
 In the event that the Trustee or the holders of not less than twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding hereunder have declared the principal of, and accrued and unpaid
interest (including any Additional Interest) on, the Notes, to be due and payable immediately in accordance with Section 5.01, and the Company shall have failed forthwith to pay such amounts, the Trustee, in its own name and as trustee of an
express trust, after being furnished suitable indemnity pursuant to Section 6.01, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid (including such
further amounts as shall be sufficient to cover the reasonable costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred by the Trustee hereunder
other than through its negligence or bad faith), and may prosecute any such action or proceeding to judgment or final degree, and may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the
manner provided by law out of the property of the Company or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable. 
 In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in
case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other
obligor, or in the case of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the
Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 5.02, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest (including any Additional Interest) 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 6.06; 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, 

  

 31 








 
expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 6.06 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 which 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. 
 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. 
 Section 5.03. Application of Monies Collected by Trustee. 
 Any monies collected by the Trustee pursuant to this Article 5 with respect to the Notes shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon
presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the payment of all amounts due the Trustee under Section 6.06; 
 Second, in case the principal of the outstanding
Notes shall not have become due and be unpaid, to the payment of interest (including any Additional Interest) on the Notes in default in the order of the maturity 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, such payments to be made ratably to the Persons entitled thereto; 
 Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole
amount (including, if applicable, payments in respect of the Conversion Obligation and Additional Shares) then owing and unpaid upon the Notes for principal and interest (including any Additional Interest), with interest on the overdue principal (to
the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes, and in case such 

  

 32 








 
monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and interest (including
any Additional Interest) without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate
of such principal and accrued and unpaid interest; and 
 Fourth, to the payment of the remainder, if any, to the Company or any other Person
lawfully entitled thereto. 
 Section 5.04. 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 twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding shall
have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder 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 sixty (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 pursuant to Section 5.07; it being
understood and intended, and being expressly covenanted by the holder of every Note with every other holder and the Trustee, that no one or more Noteholders shall have any right in any manner whatever by virtue of or by availing of any provision of
this Indenture to affect, disturb or prejudice the rights of any other Noteholder, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Noteholders (except as otherwise provided herein). For the protection and enforcement of this Section 5.04, 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 accrued and unpaid interest (including any Additional Interest) on such Note, on or after the respective due dates expressed in such Note, 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 his own behalf and for his own benefit, may enforce, and may
institute and maintain any proceeding suitable to enforce, his rights of conversion as provided herein. 
  

 33 








 Section 5.05. 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 5.06. Remedies Cumulative and Continuing. 
 Except as provided in the last paragraph of Section 2.08, all powers and remedies given by this Article 5 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof
or of any other powers and remedies available to the Trustee or the holders of the 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 5.04, every power and remedy given by this Article 5 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 5.07. Direction of Proceedings and Waiver of Past 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 7.04 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. 
 Subject to Section 5.01, the holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 7.04 may, on behalf of the holders of all of the Notes waive any past
Default or Event of Default hereunder and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing events of default, other than nonpayment of the principal
of and interest (including additional interest, if any) on the notes that have become due solely by such declaration of acceleration, have been cured or waived except for (i) a Default in the payment of and accrued and unpaid interest
(including Additional Interest, if any) on, or the principal of, the Notes when due which has not been cured pursuant to the provisions of Section 5.01, (ii) a Default in the payment of the Fundamental Change Purchase Price, (iii) a
failure by 

  

 34 








 
the Company to deliver shares of Common Stock (and cash in lieu of fractional shares) upon conversion of the Notes, or (iv) a default in respect of a
covenant or provisions hereof which under Article 9 cannot be modified or amended without the consent of each holder of an outstanding Note affected thereby. Upon any such waiver, the Company, the Trustee and the holders of the Notes shall be
restored to their former positions and rights hereunder, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have
been waived as permitted by this Section 5.07, 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 5.08. Notice of Defaults. 
 The Trustee shall, within ninety (90) days after the occurrence and continuance of a Default (or within fifteen (15) days after it is known to
the Trustee, if later), 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 pursuant to Section 5.01(a), (b), (d), (e) or (g), the Trustee shall be protected in withholding such notice if and so long as a committee of trust officers of the
Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders. 
 Section 5.09. Undertaking to Pay
Costs. 
 All parties to this Indenture agree, and each holder of any Note by his 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, against any party litigant in such suit, having due regard to the merits and good
faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 5.09 (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 ten percent (10%) in principal amount of the Notes at the time outstanding determined in accordance with Section 7.04, or to any suit instituted by any Noteholder for the enforcement
of the payment of the principal of and accrued and unpaid interest (including Additional Interest, if any) on any Note on or after the due date expressed in such Note or to any suit for the enforcement of the right to convert any Note in accordance
with the provisions of Article 13.

 Article 6 
 CONCERNING THE TRUSTEE 
 Section 6.01. 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 which may
have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived) the Trustee shall exercise such of the rights and
powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; provided that if an Event
of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the holders unless such holders have offered to the Trustee reasonable
indemnity or security against loss, liability or expense. 
 No provision of this Indenture shall be construed to relieve the Trustee from
liability for its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct, except that: 
 (a)
prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred: 
 (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and, after it has been qualified thereunder, the Trust Indenture Act, and the Trustee shall not be liable except for the
performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and 
 (ii) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of
the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which 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; 
 (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
established by a court of competent jurisdiction that the Trustee was grossly negligent in ascertaining the pertinent facts; 
 (c) the
Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith and either (i) believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture or
(ii) 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 7.04 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; 
  

 36 








 (d) whether or not therein provided, every provision of this Indenture relating to the conduct or
affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section; 
 (e) the Trustee
shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-registrar with
respect to the Notes; 
 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture,
requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless such Responsible Officer of the Trustee had actual knowledge of such event;

 (g) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest
bearing trust account. In no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation of any such investments prior to its stated maturity or
the failure of the party directing such investments prior to its stated maturity or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any
amounts held hereunder in the absence of such written investment direction from the Company; and 
 (h) in the event that the Trustee is also
acting as Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 6 shall also be afforded to it in its capacity as such. 
 None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of its rights or powers. 
 Section 6.02. Reliance on Documents,
Opinions, Etc. 
 Except as otherwise provided in Section 6.01: 
 (a) the Trustee may conclusively rely and shall be fully protected in acting upon any resolution, certificate, statement, instrument, opinion, report,
notice, request, consent, order, bond, note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties; 
 (b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officer’s Certificate (unless
other evidence in respect thereof be herein specifically prescribed), and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company; 
 (c) the Trustee may consult with counsel and require an Opinion of Counsel and any advice of such counsel or Opinion of Counsel shall be full and
complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 
  


 37 








 (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this
Indenture at the request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities which may be incurred therein or thereby; 
 (e) the Trustee shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or
attorney; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not
reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require indemnity satisfactory to the Trustee from the Noteholders against such expenses or liability as a condition to so proceeding;
the reasonable expenses of every such examination shall be paid by the Company or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Company upon demand; 
 (f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians,
nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney appointed by it with due care hereunder; 
 (g) the permissive rights of the Trustee enumerated herein shall not be construed as duties; 
 (h) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon Officer’s Certificates or Opinions of Counsel furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such Certificates or Opinions which 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
mathematical calculations or other facts stated therein); 
 (i) the Trustee may request that the Company deliver an Officer’s
Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any person authorized to sign Officer’s
Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded; 
  

 38 








 (j) No provision of this Indenture shall be deemed to impose any duty or obligation on the Trustee to
take or omit to take any action, or suffer any action to be taken or omitted, in the performance of its duties or obligations under this Indenture, or to exercise any right or power thereunder, to the extent that taking or omitting to take such
action or suffering such action to be taken or omitted would violate applicable law binding upon it; and 
 (k) The rights, privilege,
protections, immunities and benefits provided to the Trustee hereunder (including the right to be indemnified) are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including, but not limited to its capacity
as Paying Agent and Conversion Agent) and to each of its agents, custodians and other persons duly employed by the Trustee hereunder. 
 In
no event shall the Trustee be liable for any consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of
action other than through the Trustee’s willful misconduct or gross negligence. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall
have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or by any holder of the Notes at the Corporate Trust Office of the Trustee,
and such notice references the Notes and this Indenture; and the permissive rights of the Trustee enumerated herein shall not be construed as duties. 
 Section 6.03. No Responsibility for Recitals, Etc. 
 The recitals contained herein and in the Notes (except in the
Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. The
Trustee shall not be responsible or liable for any loss suffered in connection with any investment of funds made by it in accordance with this Indenture or at the direction of the Company. Except for information provided by the Trustee concerning
the Trustee, the Trustee shall have no responsibility for any information in any offering memorandum, prospectus or other disclosure material distributed with respect to the Notes. 
 Section 6.04. Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. 
 The
Trustee, any Paying Agent, any Conversion Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, Paying Agent, Conversion Agent or Note
Registrar. 
 Section 6.05. Monies to be Held in Trust. 
 Subject to the provisions of Section 11.04, all monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the

 39 








 
except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed from
time to time by the Company and the Trustee. 
 Section 6.06. Compensation and Expenses of Trustee. 
 The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services
rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will
pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and
the expenses and disbursements of its agents and counsel and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its gross negligence, willful misconduct or bad faith. The Company also
covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, liability
or expense incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection
with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this
Section 6.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee
as such, except, subject to the effect of Section 5.03, funds held in trust herewith for the benefit of the holders of particular Notes prior to the date of the accrual of such unpaid compensation or identifiable claim. The Trustee’s right
to receive payment of any amounts due under this Section 6.06 shall not be subordinate to any other liability or Indebtedness of the Company. The obligation of the Company under this Section 6.06 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 6.06 shall extend to the officers, directors, agents and employees of the Trustee. 
 When the Trustee and its agents and any
authenticating agent incur expenses or render services after an Event of Default specified in Section 5.01(j) or Section 5.01(k) occurs, the expenses and the compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws. 
 Section 6.07. Officer’s Certificate as Evidence. 
 Except as otherwise provided in Section 7.01, 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 gross 

  

 40 








 
negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an
Officer’s Certificate delivered to the Trustee, and such Officer’s Certificate, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall be full warrant to the Trustee for any
action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 
 Section 6.08. Conflicting Interests of Trustee.

 If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. 
 Section 6.09. 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 6.09, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any
time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 6.10. Resignation or Removal of Trustee. 
 (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the Noteholders at their addresses as they shall appear on the Note Register. Upon receiving such notice of
resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty (60) days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, at the expense of the Company,
petition any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 5.09, 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 6.08 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 (6) months; or 
  

 41 








 (ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 6.09 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 5.09, any Noteholder who has been a bona fide holder of a Note or Notes for at least six (6) 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 7.04, may
at any time remove the Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless within ten (10) 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 provided in Section 6.10(a), may petition any court of competent jurisdiction for an appointment of a successor trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 6.10 shall
become effective upon acceptance of appointment by the successor trustee as provided in Section 6.11. 
 Section 6.11. Acceptance by Successor
Trustee. 
 Any successor trustee appointed as provided in Section 6.10 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 6.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to
act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property and funds 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 6.06. 
  

 42 








 No successor trustee shall accept appointment as provided in this Section 6.11 unless at the time of
such acceptance such successor trustee shall be qualified under the provisions of Section 6.08 and be eligible under the provisions of Section 6.09. 
 Upon acceptance of appointment by a successor trustee as provided in this Section 6.11, 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 (10) 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 6.12. 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 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
succeeding to all or substantially all of the corporate trust business of the Trustee such corporation shall be qualified under the provisions of Section 6.08 and eligible under the provisions of Section 6.09. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated, and in case at that
time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name
of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the
right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 
 Section 6.13. 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), 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). 
  

 43 








 Section 6.14. 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 (3) Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date),
unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in response to such proposal specifying the action to be taken or omitted. 
 Article 7 
 CONCERNING
THE NOTEHOLDERS 
 Section 7.01. Action by Noteholders. 
 Notwithstanding anything to the contrary contained in this Indenture, all Notes issued under this Indenture shall vote and consent on all matters as one
class; provided, however, that (i) for purposes of determining which Notes are outstanding for consent or voting purposes hereunder, the provisions of Section 7.04 shall apply and (ii) in determining whether the Trustee
shall be protected in making a determination whether the holders of the requisite principal amount of outstanding Notes are present at a meeting of holders of Notes for quorum purposes or have consented to or voted in favor of any request, demand,
authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Notes which a Responsible Officer actually knows to be held by the Company or an Affiliate of the Company
shall not be considered outstanding. 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 8, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders and, except as herein otherwise expressly provided, such action shall become effective when such instrument
or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and
conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 7.01. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix, but
shall not be required to, in advance of such solicitation, a date of record for determining Noteholders entitled to take such action. The date of record if one is selected shall be not more than fifteen (15) days prior to the date of
commencement of solicitation of such action. Any request, demand, authorization, direction, notice consent, waiver or other action by a holder of any Note shall bind every future 

  

 44 








 
holder of the same Note, and the holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect
of anything done, omitted, or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Note. 
 Section 7.02. Proof of Execution by Noteholders. 
 Subject to the provisions of Section 6.01, Section 6.02 and
Section 8.05, proof of the execution of any instrument by a Noteholder or his 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 8.06. 
 Section 7.03. 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 such Note shall be registered upon the Note Register to be, and may treat him as, the
absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or
on account of the principal of and accrued and unpaid interest 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 his 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 7.04. 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 any
other obligor on the Notes or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on such Notes shall be disregarded and deemed not to be outstanding for
the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer knows are so owned
shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 7.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote
such Notes and that the pledgee is not the Company, any other obligor on the Notes or a person directly or indirectly controlling or controlled by or 

  

 45 








 
under direct or indirect common control with the Company or any such other obligor. 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 Officer’s 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 6.01, the Trustee shall be entitled to accept such Officer’s 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 7.05. Revocation of Consents; Future
Holders Bound. 
 At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 7.01, 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 7.02, 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, irrespective of whether any notation in regard
thereto is made upon such Note or any Note issued in exchange or substitution therefor. 
 Article 8

 Section 8.01. Purpose of Meetings. 
 A meeting of Noteholders may be called at any time and from time to time pursuant
to the provisions of this Article 8 for any of the following purposes:

all Notes then outstanding are present in person or by proxy or if notice is waived before or after the meeting by the holders of all Notes outstanding, and if the Company and the Trustee are either present by duly authorized representatives or
have, before or after the meeting, waived notice. 
 Section 8.03. Call of Meetings by Company or Noteholders. 
 In case at any time the Company, pursuant to a resolution of its Board of Directors, or the holders of at least ten percent (10%) in aggregate
principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Noteholders, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have
mailed the notice of such meeting within twenty (20) days after receipt of such request, then the Company or such Noteholders may determine the time and the place for such meeting and may call such meeting to take any action authorized in
Section 8.01, by mailing notice thereof as provided in Section 8.02. 
 Section 8.04. Qualifications for Voting.

such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company and its counsel. 
 Section 8.05. Regulations. 
 Notwithstanding any other provisions of this Indenture, the Trustee may make such

the Company or the Noteholders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the holders of a majority in
principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 
  

 47 








 Subject to the provisions of Section 7.04, at any meeting of Noteholders each Noteholder or
proxyholder shall be entitled to one vote for each $1,000 principal amount of Notes held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by
the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by him or instruments in writing as aforesaid duly designating him as the proxy to vote on behalf of other
Noteholders. Any meeting of Noteholders duly called pursuant to the provisions of Section 8.02 or Section 8.03 may be adjourned from time to time by the holders of a majority of the aggregate principal amount of Notes represented at the

verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting. 
 Any record so signed and verified shall be conclusive evidence of the matters therein stated. 
 Section 8.07. No Delay of Rights by Meeting. 
 Nothing contained in this Article 8 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Noteholders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in
the exercise of any right or rights conferred upon or reserved to the Trustee or to the Noteholders under any of the provisions of this Indenture or of the Notes.

 Upon the written request of the Company, accompanied by a Board Resolution authorizing the execution of
such supplemental indenture, 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 which may be therein contained and to accept the
conveyance, transfer and assignment of any property thereunder, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture which affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed by the Company
and the Trustee without the consent of the holders of any of the Notes at the time outstanding. 
 Section 9.02. Supplemental Indentures with Consent
of Noteholders. 
 With the consent (evidenced as provided in Article 7) of the holders of at least a majority in aggregate principal
amount of the Notes at the time outstanding (determined in accordance with Article 7 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 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

 Upon the written request of the Company, accompanied by a copy of the Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Noteholders as aforesaid, 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 9.02 to approve the particular form of any proposed

the Note Register a notice briefly describing such amendment. However, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the amendment. 
 Section 9.03. Effect of Supplemental Indentures. 
 Any supplemental indenture executed pursuant to the provisions of this Article 9 shall comply with the Trust Indenture Act, as then in effect, provided that this Section 9.03 shall not require such supplemental indenture or the Trustee
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, nor shall it 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. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 9, 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 9.04. Notation on Notes. 
 Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 9 may 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 15.10) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 
 Section 9.05.
Evidence of Compliance of Supplemental Indenture to be Furnished Trustee. 
 In addition to the documents required by
Section 15.05, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 9. 
 Article 10

substantially all of the properties and assets of the Company substantially as an entirety (1) shall be organized and validly existing under the laws of the United States or any State thereof or the District of Columbia and (2) shall
expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all of the obligations of the Company under the Notes, this Indenture and the Registration Rights Agreement
and, to the extent applicable, otherwise comply with the provisions of Section 13.06;

supplemental indenture, comply with this Article 10 and that all conditions precedent herein provided for relating to such transaction have been satisfied. 
 For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise) of the properties and assets of one or more Subsidiaries, which, if such assets were owned by the 

  

 52 








 
Company, together with the assets of all of the other Subsidiaries of the Company, would constitute all or substantially all of the properties and assets of
the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company unless such transfer is to the Company or another Subsidiary. 
 The successor Person formed by such consolidation or into which the Company is merged or the successor Person to which such conveyance, transfer, sale,
lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the Company herein; and thereafter,
except in the case of a conveyance, transfer, sale, lease or other disposition and any obligations the Company may have under a supplemental indenture, the Company shall be discharged from all obligations and covenants under this Indenture and the
Notes. Subject to Section 9.02, the Company, the Trustee and the successor Person shall enter into a supplemental indenture to evidence the succession and substitution of such successor Person and such discharge and release of the Company.

 Article 11 
 SATISFACTION AND DISCHARGE OF INDENTURE 
 Section 11.01.
Discharge of Indenture. 
 When (a) the Company shall deliver to the Note Registrar for cancellation all Notes theretofore
authenticated (other than any Notes that have been destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Notes not theretofore
canceled or delivered to the Note Registrar for cancellation shall have become due and payable, whether on the Maturity Date, on any earlier Fundamental Change Purchase Date, upon conversion or otherwise, and the Company shall deposit with the
Trustee, in trust, cash or shares of Common Stock, as applicable, sufficient to pay or deliver, as the case may be, the amount of cash or number of shares of Common Stock due on the Maturity Date, any Fundamental Change Purchase Date or upon
conversion of all of the Notes (other than any Notes that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered
to the Trustee for cancellation, including principal and accrued and unpaid interest (including any Additional Interest) due thereon, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this
Indenture shall cease to be of further effect except as to (i) the right of holders to receive payments of principal of and accrued and unpaid interest (including any Additional Interest), and delivery of any unsatisfied Conversion Obligation
and unpaid Additional Shares, if any, on, the Notes and the other rights, duties and obligations of Noteholders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee, (ii) the rights, obligations and
immunities of the Trustee hereunder and (iii) the obligations of the Company under Section 6.06, and the Trustee, on written demand of the Company accompanied by an Officer’s Certificate and an Opinion of Counsel as required by
Section 15.05 and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses
thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Notes. 
  

 53 








 Section 11.02. Deposited Monies to be Held in Trust by Trustee. 
 Subject to Section 11.04, all monies deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it to the
payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the holders of the particular Notes for the payment of which such monies have been deposited with the Trustee, of all sums due thereon
for principal and accrued and unpaid interest. 
 Section 11.03. Paying Agent to Repay Monies Held. 
 Upon the satisfaction and discharge of this Indenture, all monies then held by any Paying Agent of the Notes (other than the Trustee) shall, upon written
request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies. 
 Section 11.04. Return of Unclaimed Monies. 
 Subject to the requirements of applicable law, any
monies deposited with or paid to the Trustee for payment of the principal of or accrued and unpaid interest on, Notes and not applied but remaining unclaimed by the Noteholders for two years after the date upon which the principal of or accrued and
unpaid interest on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on written request and all liability of the Trustee shall thereupon cease with respect to such monies; and the holder
of any of the Notes shall thereafter look only to the Company for any payment which such holder may be entitled to collect unless an applicable abandoned property law designates another person. The Trustee shall, promptly after such payment of the
principal of, and any accrued and unpaid interest, on Notes, as described in this Section 11.04 and upon written request of the Company, return to the Company any funds in excess of the amount required for such payment. 
 Section 11.05. Reinstatement. 
 If (i) the
Trustee or the Paying Agent is unable to apply any money in accordance with Section 11.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application and
(ii) the holders of at least a majority in principal amount of the then outstanding Notes so request by written notice to the Trustee, the Company’s obligations under this Indenture shall be revived and reinstated as though no deposit had
occurred pursuant to Section 11.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with Section 11.02; provided, however, that if the Company makes any payment of interest
(including any Additional Interest) on or principal of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Noteholders to receive such payment from the money held by the Trustee or Paying
Agent. 
  

 54 








 Article 12 
 IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS 
 Section 12.01. Indenture and Notes Solely Corporate Obligations. 
 No recourse for the payment of the principal of, or accrued and unpaid interest on, any Note, or 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, or because of the creation of any Indebtedness represented thereby, shall be had against any past, present or future incorporator, stockholder, employee,
agent, officer or director or Subsidiary of the Company as such or of any successor corporation, either directly or through the Company or any successor corporation, 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 issue of the
Notes. 
 Article 13 
 CONVERSION OF NOTES 
 Section 13.01. Conversion Right. 
 (a) Subject to and upon compliance with the provisions of this Article 13, a holder of a Note shall have the right, at such holder’s option, to
convert all or any portion (if the portion to be converted is $1,000 or an integral multiple of $1,000) of the principal amount of such Note into a number of shares of Common Stock equal to the product of (x) the Conversion Rate in effect on
the date of conversion times (y) the quotient of the principal amount at Issuance of the Note or portion thereof surrendered for conversion divided by 1,000: 
 (i) at any time prior to the Maturity Date unless such Note has been previously repurchased by the Company; or 
 (ii) as provided in clause (b) of this Section 13.01. 
 The Company’s obligations in respect of conversion of the Notes as provided above are referred to as the “Conversion Obligation.”

 (b) In addition, in the event that the Company consolidates or merges with or into another Person, or is a party to a binding share
exchange pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in Section 13.06, then the Notes may be surrendered for conversion at any time from and after the date which is 15 calendar days
prior to the date the Company announces by Public Notice as the anticipated effective time of such transaction until 15 calendar days after the effective date of such transaction, irrespective of whether such transaction constitutes a Fundamental
Change. 
 (c) Notwithstanding the foregoing, a Note in respect of which a holder has delivered a Fundamental Change Purchase Notice
exercising such holder’s right to require the Company to repurchase such Note may be converted only if such Fundamental Change Purchase Notice is withdrawn in accordance with Section 14.01(c). 
  

 55 








 (d) A holder of Notes shall not be entitled to any rights of a holder of Common Stock until such holder
has converted its Notes to Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article 13. 
 Section 13.02. Conversion Procedures; Conversion Rate; Fractional Shares. 
 (a) Each Note shall be convertible at the
office of the Conversion Agent into fully paid and nonassessable shares of Common Stock (calculated to the nearest 1/1,000th of a share). 
 The Conversion Agent shall notify the Company when it receives a Conversion Notice. The Company shall determine the number of shares of Common Stock and/or the amount of cash, if any, that the holder that submitted the Conversion Notice is
entitled to receive upon surrender of the Notes covered by that Conversion Notice. A certificate for the number of full shares of Common Stock into which the Notes are converted (and cash in lieu of fractional shares) shall be delivered to such
holder, assuming all of the other requirements have been satisfied by such holder, as soon as practicable. Notwithstanding the foregoing, the Company shall not be required to deliver certificates for Common Stock while the stock transfer books for
such stock or the security register are duly closed for any purpose, but certificates for Common Stock shall be issued and delivered as soon as practicable after the opening of such books or security register. 
 The Company shall not issue fractional shares of its Common Stock upon conversion of the Notes. In lieu thereof, the Company shall pay in cash the value
of such fractional shares based upon the Closing Sale Price of its Common Stock on the Trading Day immediately prior to the Conversion Date. 
 Upon conversion, a Noteholder will not receive any separate cash payment for accrued and unpaid interest except as set forth below. The Company’s settlement of the Conversion Obligation as described above shall be deemed to satisfy its
obligation to pay the principal amount of the Note and accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest and Additional Interest, if any, to, but not
including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after the close of business on a record date and prior to the next
succeeding Interest Payment Date, holders of such Notes as of the close of business on the record date will receive the interest (including any Additional Interest) 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 regular 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 (including any Additional Interest) payable on the Notes so converted; provided, however, that no such payment need be made (1) if the Company has specified a Fundamental 

  

 56 








 
Change Purchase Date that is after a record date and on or prior to the corresponding Interest Payment Date; (2) in respect of any conversion that
occurs after the record date immediately preceding the Maturity Date; or (3) to the extent of any Defaulted Interest existing at the time of conversion with respect to such Note. Except as described above, no payment or adjustment will be made
for accrued and unpaid interest or Additional Interest on any Notes when they are converted. Notwithstanding the foregoing, accrued interest and Additional Interest, if any, will be payable upon any conversion of Notes made concurrently with or
after acceleration of the Notes following an Event of Default. 
 If a holder has exercised its right to require the Company to repurchase
its Notes pursuant to Article 14, such holder’s conversion rights on the Notes so subject to repurchase shall expire at 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Purchase Date.
Notwithstanding the foregoing, a Note in respect of which a holder has delivered a Fundamental Change Purchase Notice exercising such holder’s right to require the Company to repurchase such Note may be converted only if such Fundamental Change
Purchase Notice is withdrawn in accordance with Section 14.01(c) and, if the Note is a Global Note, if such holder complies with applicable Depositary procedures. 
 (b) Before any holder shall be entitled to convert any Notes into Common Stock, such holder shall, in the case of Global Notes, comply with the Applicable Procedures, and in the case of Definitive Notes, surrender
such Notes, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and shall give written notice to the Company at said office or place in the form of the Conversion Notice attached to the Note (the “Conversion
Notice”) that such holder elects to convert the same and shall state in writing therein the principal amount of Notes to be converted (in whole or in part so long as the principal amount to be converted is in multiples of $1,000) and the
name or names (with addresses) in which such holder wishes the certificate or certificates for Common Stock to be issued. 
 Before any such
conversion, a holder also shall pay all funds required, if any, relating to interest or Additional Interest, if any, on the Notes, as provided in Section 13.02(f), and all taxes or duties, if any, as provided in Section 13.02(f).

 If more than one Note shall be surrendered for conversion at one time by the same holder, the number of shares of Common Stock that shall
be deliverable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 
 If shares of Common Stock to be issued upon conversion of a Restricted Security are to be issued in the name of a Person other than the holder of such
Restricted Security, such holder shall deliver to the Conversion Agent such certifications, legal opinions or other information as the Conversion Agent or the Company may reasonably require as to compliance with the restrictions on transfer
applicable to such Restricted Security; provided that the Conversion Agent shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other
information. The Company shall not be required to issue Common Stock upon conversion of any such Restricted Security to a Person other than the holder if such Restricted Security is not so accompanied by a such certifications, legal opinions or
other information and the Registrar shall 

  

 57 








 
not be required to register Common Stock upon conversion of any such Restricted Security in the name of a Person other than the holder if such Restricted
Security is not so accompanied by such certifications, legal opinions or other information. 
 (c) A Note shall be deemed to have been
converted immediately prior to 5:00 p.m., New York City time, on the date on which all of the conversion requirements set forth in Section 13.02(b) have been satisfied (the “Conversion Date”), and the person or persons entitled
to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such Common Stock as of 5:00 p.m., New York City time, on such date. 
 (d) In case any Definitive 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 (subject to the provisions of Section 13.02(f)), a new Note or Notes in authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Definitive Notes. 
 (e) If and only to the extent a holder elects to convert Notes in connection with
a transaction described under clauses (i) or (ii) of the definition of Fundamental Change pursuant to which 10% or more of the consideration for the Common Stock (other than cash payments for fractional shares and cash payments made in
respect of dissenters’ appraisal rights) in such Fundamental Change transaction consists of cash or securities (or other property) that are not traded or scheduled to be traded immediately following such transaction on a U.S. national
securities exchange or the Nasdaq National Market, such holder will be entitled to receive, in addition to a number of shares of Common Stock equal to the Conversion Rate per $1,000 principal amount of Notes, an additional number of shares of Common
Stock (the “Additional Shares”) as described below; provided, however, that if the Stock Price paid in connection with such transaction is greater than $50.00 or less than $10.69 (subject in each case to adjustment as
described below), no Additional Shares shall be issued. No Additional Shares shall be issuable under this Section 13.02(e) unless the holder elects to convert the Notes in connection with such Fundamental Change transaction. 
 The number of Additional Shares issuable in connection with the conversion of Notes as described in the immediately preceding paragraph will be
determined by reference to the table attached as Schedule A hereto, based on the Effective Date of such Fundamental Change transaction and the Stock Price paid in connection with such Fundamental Change transaction; provided that if the Stock Price
is between two Stock Price amounts in the table or such Effective Date is between two Effective Dates in the table, the number of Additional Shares will be determined by the Company by a straight-line interpolation between the number of Additional
Shares set forth for the higher and lower Stock Price amounts and the two Effective Dates, as applicable, based on a 365-day year. The “Effective Date” with respect to a Fundamental Change transaction means the date on which such
Fundamental Change becomes effective. The “Stock Price” shall be the price paid per share for Common Stock in such Fundamental Change. If holders of Common Stock receive only cash in such Fundamental Change, the Stock Price shall be
the cash amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Closing Sale Price on the five trading days prior to but not including the effective date of such Fundamental Change. 
  

 58 








 The Stock Prices set forth in the first row of the table in Schedule A hereto will be adjusted as of any
date on which the Conversion Rate of the Notes is adjusted pursuant to Section 13.03. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the
Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares will be adjusted in the same manner as the Conversion
Rate as set forth in Section 13.03. 
 Notwithstanding the foregoing, in no event will the total number of shares of Common Stock
issuable upon conversion exceed 93.5454 per $1,000 principal amount of Notes, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 13.03. 
 (f) If a holder submits a Note for conversion, the Company shall pay all documentary, stamp or similar issue or transfer tax, if any, which may be
imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares of Common Stock upon the conversion. However, the holder shall pay any such tax which 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 which will be due because the shares are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or
regulations. 
 (g) Except as provided in Section 13.03, no adjustment shall be made for dividends on any shares issued upon the
conversion of any Note as provided in this Article 13. 
 Section 13.03. Adjustment of Conversion Rate. 
 The Conversion Rate shall be adjusted from time to time by the Company as follows: 
 (a) If the Company issues shares of Common Stock as a dividend or distribution on shares of the Common Stock, or effects a share split or share
combination, the Conversion Rate shall be adjusted based on the following formula: 
  

													
		 	CR'	 	=	 	CR0	 	x	 	 OS'
	  	
		 	 	 	 	 	OS0	  	

 where 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Ex-Dividend Date for such dividend or distribution or the effective date of such share split or combination, as the case may
be;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or combination, as the case may
be;

  

 59 









					
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or combination, as the
case may be; and
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after such dividend or distribution, or the effective date of such share split or combination, as the case may be.

 Such adjustment shall become effective immediately after (i) the Ex-Dividend Date fixed for such dividend or
distribution or (ii) the effective date for such share split or share combination, as applicable. To the extent any dividend or distribution of the type described in this Section 13.03(a) is declared but not so paid or made, or the
outstanding shares of Common Stock are not split or combined, as the case may be, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or split or
combine the outstanding shares of Common Stock, as the case may be, to the Conversion Rate that would then be in effect if such dividend, distribution, split or share combination had not been declared. 
 (b) If the Company distributes to all holders of its Common Stock rights or warrants entitling them to purchase, for a period of not more than forty-five
(45) calendar days after the Ex-Dividend Date for the applicable distribution, shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the ten (10) consecutive Trading Day
period ending on the Trading Day immediately preceding the Ex-Dividend Date of such distribution, the Conversion Rate shall be adjusted based on the following formula: 
  


													
		 	CR'	 	=	 	CR0	 	x	 	 OS0 + X

	  	
		 	 	 	 	 	OS0 + Y	  	

 where 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Ex Dividend Date for such distribution;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the Ex-Dividend Date for such distribution;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Ex-Dividend Date for such distribution;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and
			
	Y	  	=	  	the number of shares of 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 Common Stock over the ten
(10) consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend relating to such distribution.

  

 60 








 If any right or warrant described in this Section 13.03(b) is not exercised or exchanged prior to the expiration of
the exercisability or exchangeability thereof, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such right or warrant had not been so issued. Any adjustment made pursuant to this
Section 13.03(b) shall become effective immediately after the Ex-Dividend Date for the applicable distribution. 
 For purposes of this
Section 13.03(b), in determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Last Reported Sale Prices, and in determining the aggregate exercise or conversion price
payable for such shares of Common Stock, 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, the value of such consideration, if other than
cash, to be determined by the Board of Directors. 
 (c) If the Company distributes shares of its Capital Stock, evidences of its
Indebtedness or other assets or property of the Company to all holders of its Common Stock, excluding (i) dividends or distributions referred to in Section 13.03(a), (ii) dividends or distributions of rights or warrants referred to in
Section 13.03(b), (iii) dividends or distributions paid exclusively in cash and (iv) Spin-Offs described below in this Section 13.03(c) (any of such shares of Capital Stock, Indebtedness, or other asset or property hereinafter in
this Section 13.03(c) called the “Distributed Property”), then, in each such case the Conversion Rate shall be adjusted based on the following formula: 
  

													
		 	CR'	 	=	 	CR0	 	x	 	 SP0

	  	
		 	 	 	 	 	SP0 – FMV	  	

 where 
  

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

 Such adjustment shall become effective immediately after the Ex-Dividend Date for such distribution. 

 

 61 








 With respect to an adjustment pursuant to this Section 13.03(c) where there has been a payment of a
dividend or other distribution on the Common Stock or shares of Capital Stock of any class or series, or similar Equity Interest, of or relating to a Subsidiary or other business unit (a “Spin-Off”), the Conversion Rate in effect
immediately before 5:00 p.m., New York City time, on the tenth (10th) Trading Day immediately following, and including, the effective date of the Spin-Off will be increased based on the following formula: 
  

													
		 	CR'	 	=	 	CR0	 	x	 	 FMV0 + MP0
	  	
		 	 	 	 	 	MP0	  	

 where 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the tenth (10th) Trading Day immediately following, and including the effective date of the Spin-Off;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the tenth (10th) Trading Day immediately following, and including, 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 Common Stock applicable to one share of Common Stock (determined for
purposes of the definition of “Last Reported Sale Price” as if such Capital Stock were the Common Stock) over the first ten (10) consecutive Trading Day period immediately following, and including, the effective date of the Spin-Off;
and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the first ten (10) consecutive Trading Day period following, and including, the effective date of the
Spin-Off.

 Such adjustment shall occur immediately after the tenth (10th) Trading Day immediately following, and
including, the effective date of the Spin-Off; provided that in respect of any conversion within the ten (10) Trading Days following the effective date of any Spin-Off, references within this paragraph (c) to ten (10) 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 relevant Conversion Date in determining the applicable Conversion Rate. 
 If any such dividend or distribution described in this Section 13.03(c) is declared but not paid or made, the new Conversion Rate shall be
readjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (d) If the
Company pays any cash dividend or distribution to all holders of the Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  

													
		 	CR'	 	=	 	CR0	 	x	 	 SP0

	  	
		 	 	 	 	 	SP0 – C	  	

  

 62 








 where, 
  

					
	CR0	  	=	  	the new Conversion Rate in effect immediately prior to the Ex Dividend Date for such dividend or
distribution;
			
	CR'	  	=	  	the new Conversion Rate in effect immediately after the Ex Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company dividends or distributes to holders of Common Stock.

 Such adjustment shall become effective immediately after the Ex Dividend Date for such dividend or distribution.
If such dividend or distribution is not so paid or made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for all or any portion of the Common Stock,
to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or
exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  

													
		 	CR'	 	=	 	CR0	 	x	 	 AC + (SP' x OS')
	  	
		 	 	 	 	 	OS0 x SP1	  	

 where 
  

					
	CR0	  	=	  	the Conversion Rate in effect on the last Trading Day of the ten (10) consecutive Trading Day
period commencing on the Trading Day next succeeding the date such tender or exchange offer expires;
			
	CR'	  	=	  	the new Conversion Rate in effect immediately following the last Trading Day of the ten (10) consecutive Trading Day period commencing on the Trading Day next succeeding the date such
tender or exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares purchased in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the expiration of such tender or exchange offer;

  

 63 









					
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after the expiration of such tender or exchange offer (after giving effect to the purchase or exchange of shares pursuant to such
tender or exchange offer); and
			
	SP'	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the ten (10) consecutive Trading Day commencing on the Trading Day next succeeding the date such tender or exchange offer
expires.

 Such adjustment shall become effective immediately following the tenth (10th) Trading Day next succeeding the
date such tender or exchange offer expires; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the ten Trading Days following the date that any tender or exchange offer expires, references within this
Section 13.03(e) to ten (10) Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date such tender or exchange offer expires and the relevant conversion date. If the Company or one of
its Subsidiaries is obligated to purchase the Company’s Common Stock pursuant to any such tender or exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new
Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such tender or exchange offer had not been made. 
 (f) Notwithstanding any provision herein to the contrary, the Company will not adjust the Conversion Rate: 
 (i)
upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in shares of Common
Stock under any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase shares of
Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 
 (iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible
security not described in clause (ii) above and outstanding as of the date the Notes were first issued; 
 (iv) for a
change in the par value of the Common Stock; or 
 (v) for accrued and unpaid interest (including any Additional Interest).

 The Company will not make any adjustment to the Conversion Rate except as specifically set forth in this Article 13. Further, in the event
of an adjustment to the Conversion Rate pursuant to Section 13.03(d) and (e) above, in no event will the conversion rate exceed 93.5454 shares of Common Stock per $1,000 principal amount of notes, subject to adjustment pursuant to
Section 13.03(a), (b) and (c) above. 
  

 64 








 To the extent the Notes become convertible into cash, assets or property, no adjustment shall be made
thereafter as to the cash, assets or property. Interest shall not accrue on such cash, assets or property. 
 (g) All calculations and other
determinations under this Article 13 shall be made by the Company and shall be made to the nearest cent or to the nearest one-thousandth (1/1,000) of a share, as the case may be. No adjustment shall be made for the Company’s issuance of
Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities, other than as provided in this Section 13.03. No adjustment shall be made to the Conversion Rate unless such
adjustment, taken together with all other as-yet-unmade adjustments, would require a change of at least one percent (1%) in the Conversion Rate then in effect at such time. However, the Company shall carry forward any adjustments that are less
than one percent (1%) of the Conversion Rate and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than one percent (1%), upon conversion, a Fundamental Change or the Maturity Date. If the application
of the foregoing formulae in Section 13.03(a) through (e) (other than as a result of a share split or share combination) would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made. 
 (h) 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 Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. The Trustee and Conversion Agent may conclusively rely on the accuracy of the
Conversion Rate adjustment provided by the Company. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s 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 his last address appearing on the Note Register provided for in
Section 2.06 of this Indenture, within twenty (20) days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 
 (i) For purposes of this Section 13.03, 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. 
 (j) No adjustments to the Conversion Rate will be made if Noteholders participate (as a result of holding the Notes, and at the same time as Common Stock holders participate) in any of the transactions described above as if such Noteholders
held a number of shares of the Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Noteholder, without having to convert their Notes. 
  

 65 








 (k) The Company from time to time may increase the Conversion Rate, to the extent permitted by law, by
any amount for any period of time if the period is at least twenty (20) days and the Company provides fifteen (15) days’ prior written notice of any increase in the Conversion Rate to the Trustee and the Noteholders. The Company may
also make such an increase to the Conversion Rate as the Board of Directors determines would avoid or diminish income tax to holders of shares of Common Stock in connection with a dividend or distribution of stock (or rights to acquire stock) or
from any event treated as such for income tax purposes. 
 Section 13.04. 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 13.05. Effect of
Reclassification, Consolidation, Merger or Sale. 
 In the event of (i) any reclassification or change of the outstanding shares of
Common Stock (other than changes as a result of a subdivision or combination), (ii) any consolidation, merger or combination involving the Company, or (iii) any sale or conveyance of all or substantially all of the property and assets of
the Company to another Person or any statutory share exchange, in each case as a result of which the Company’s Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any
combination thereof) (any such event a “Reorganization Event”), then: 
 (a) the Company or the successor or purchasing
Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required
to so comply) permitted under Section 9.01(b) providing for the conversion and settlement of the Notes as set forth in this Indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 13 and the Trustee may conclusively rely on the determination by the Company of the equivalency of such adjustments. If, in the case of any Reorganization 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 purchase rights set forth in Article 14 herein. 
 In the event the Company shall execute a supplemental indenture pursuant to this Section 13.05, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons
therefore, the kind or amount of cash, securities or property or asset that will constitute the Reference Property after any such Reorganization 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. 
  

 66 








 (b) Notwithstanding the provisions of Section 13.05(a), at the effective time of such Reorganization
Event, the right to convert each $1,000 principal amount of Notes will be changed to a right to convert such Note by reference to the kind and amount of cash, securities or other property 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”) such that from and after the effective time of such transaction, a Noteholder will be entitled
thereafter to convert its Notes into the same type (and in the same proportion) of Reference Property. For purposes of determining the constitution of Reference Property, the type and amount of consideration that a holder of Common Stock would have
been entitled to in the case of reclassifications, consolidations, mergers, sales or conveyances of property or assets or other transactions that cause the Common Stock to be converted into the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election) will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election. The
Company shall not become a party to any such transaction unless its terms are consistent with the preceding. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes in accordance with the provisions of
Article 13 hereof prior to the effective date. 
 (c) The Company shall cause notice of the execution of such supplemental indenture to be
mailed to each Noteholder, at his address appearing on the Note Register provided for in this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such
supplemental indenture. 
 (d) The above provisions of this Section 13.05 shall similarly apply to successive Reorganization Events.

 Section 13.06. Certain Covenants. 
 Before taking any action which would cause an adjustment reducing the Conversion Rate below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate action which
may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate. 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 changes with respect to the issue thereof. 
 Section 13.07. Responsibility of Trustee. 
 Notwithstanding any provision of this Indenture to the contrary, 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 whether any facts exist which may require any adjustment 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 or property, which may at any 

  

 67 








 
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 13.05 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 13.05 or to any
adjustment to be made with respect thereto, but, subject to the provisions of Section 6.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate
(which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 
 Section 13.08. Notice to Holders 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 13.03; 
 (b) the Company shall authorize the granting to all or substantially all of the holders of its Common Stock of
rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants that would require an adjustment in the Conversion Rate pursuant to Section 13.03; 
 (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 shareholders of the Company is required, or of the sale or conveyance
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 his 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 (20) days prior to the applicable date specified in clause (x) or (y) below, as the case may be, a notice stating
(x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights 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 (y) the date on which such reclassification, consolidation, merger, sale, conveyance, 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 

  

 68 








 
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 13.09. Shareholder Rights Plans. 
 To the
extent the Company has a rights plan in effect upon conversion of the Notes, the holders shall receive, in addition to the shares of Common Stock issuable upon such conversion, the associated rights issued under such rights plan unless, prior to
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 distributed to all holders of Common Stock shares of the Company’s Capital Stock,
evidences of Indebtedness or assets as described in Section 13.03(c) above, subject to readjustment in the event of the expiration, termination or redemption of such rights. 
 Section 13.10. Withholding Taxes for Adjustments in Conversion Rate. 
 If the Company pays
withholding taxes on behalf of a holder as a result of an adjustment to the Conversion Rate, the Company may, at its option, set off such payments against payments of cash and shares of Common Stock on the Notes. 
 Article 14 
 PURCHASE
OF NOTES AT OPTION OF HOLDERS 
 Section 14.01. Fundamental
Change Put. 
 (a) In the event that a Fundamental Change shall occur at any time prior to the Maturity Date, each holder shall have the
right, at the holder’s option, but subject to the provisions of this Section 14.01, to require the Company to purchase, and upon the exercise of such right, the Company shall purchase, all of such holder’s Notes, or any portion of the
principal amount thereof that is equal to $1,000 or an integral multiple thereof, as directed by such holder pursuant to this Section 14.01, on the date designated by the Company (the “Fundamental Change Purchase Date”) that is
a Business Day no later than 35 Business Days after the date of notice pursuant to Section 14.01(b) of the occurrence of a Fundamental Change (subject to extension to comply with applicable law). The Company shall be required to purchase such
Notes at a purchase price in cash equal to 100% of the principal amount plus any accrued and unpaid interest and Additional Interest, if any, to, but excluding, the Fundamental Change Purchase Date (the “Fundamental Change Purchase
Price”). In the event that a Fundamental Change Purchase Date is a date that is after any Record Date and on or before the corresponding Interest Payment Date, the Company shall be required to pay accrued and unpaid interest and Additional
Interest, if any, to the holder of the repurchased Notes at the close of business on the corresponding Record Date if different from the holder on the Record Date, in which case the Fundamental Change Purchase Price shall be 100% of the principal
amount of the repurchased Notes. 
 (b) No later than ten (10) Business Days after the occurrence of a Fundamental Change, the Company
shall mail a written notice of the Fundamental Change (a “Fundamental 

  

 69 








 
Change Company Notice”) by first class mail to the Trustee (and the Paying Agent if the Trustee is not then acting as Paying Agent) and to each
holder at its address shown in the Register of the Registrar, and to beneficial owners as required by applicable law. The notice shall include a form of Fundamental Change Purchase Notice to be completed by the holder and shall briefly state, as
applicable: 
 (i) the date of such Fundamental Change and, briefly, the events constituting such Fundamental Change;

 (ii) the date by which the Fundamental Change Purchase Notice must be delivered to the Paying Agent in order for a holder
to exercise the purchase right pursuant to this Section 14.01; 
 (iii) the Fundamental Change Purchase Date; 

(iv) the Fundamental Change Purchase Price; 
 (v) the name and address of the Paying Agent and Conversion Agent; 
 (vi) the Conversion Rate and any adjustment thereto that will result from the Fundamental Change; 
 (vii) that the Notes as to which a Fundamental Change Purchase Notice has been given may be converted into Common Stock pursuant to
Article 13 of this Indenture only if the Fundamental Change Purchase Notice has been withdrawn in accordance with the terms of this Indenture; 
 (viii) that the Notes must be surrendered to the Paying Agent to collect payment; 
 (ix) that
the Fundamental Change Purchase Price for any Note as to which a Fundamental Change Purchase Notice has been duly given and not withdrawn shall be paid promptly following the later of the Fundamental Change Purchase Date and the time of surrender of
such Note as described in Section 14.01(b)(ix); 
 (x) the procedures the holder must follow to exercise rights under
this Section 14.01; 
 (xi) the procedures for withdrawing a Fundamental Change Purchase Notice, including a form of
notice of withdrawal; 
 (xii) that, unless the Company defaults in making payment of such Fundamental Change Purchase Price,
interest and Additional Interest, if any, on Notes surrendered for purchase by the Company shall cease to accrue on and after the Fundamental Change Purchase Date; and 
 (xiii) the CUSIP number(s) of the Notes. 
  

 70 








 At the Company’s request, the Trustee shall give the Company’s notice of a Fundamental Change
at the Company’s expense; provided, however, that the Company makes such request at least five (5) Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice of
purchase right must be given to the holders in accordance with this Section 14.01(b); provided, further, that the text of such notice shall be prepared by the Company. 
 If any of the Notes is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of
the Depositary applicable to the purchase of Global Note. 
 Simultaneously with delivering the written notice pursuant to this
Section 14.01(b), the Company shall make a Public Notice containing all information specified in such written notice. 
 (c) A holder
may exercise its rights specified in clause (a) of this Section 14.01 upon delivery of a written notice (which shall be in substantially the form included on the reverse side of the Notes entitled “Option of holder to Elect
Purchase” hereto and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Notes, may be delivered electronically or by other means in accordance with
the Applicable Procedures) of the exercise of such rights (a “Fundamental Change Purchase Notice”) to the Paying Agent at any time on or before the tenth (10th) Business Day after the date of the Company’s notice of the
Fundamental Change (subject to extension to comply with applicable law). 
 The Fundamental Change Purchase Notice delivered by a holder
shall state (i) the relevant purchase date, (ii) if Definitive Notes, the serial number or numbers of the Note or Notes which the holder shall deliver to be purchased (if not certificated, the notice must comply with Applicable
Procedures), (iii) the portion of the principal amount of the Note which the holder shall deliver to be purchased, which portion must be $1,000 or an integral multiple thereof (or the entire principal amount of the Notes held by such holder)
and (iv) that such Note shall be purchased pursuant to the terms and conditions specified in the Notes and this Indenture. 
 Delivery
of a Note (together with all necessary endorsements) to the Paying Agent by book-entry transfer or physical delivery prior to, on or after the Fundamental Change Purchase Date at the offices of the Paying Agent (or otherwise complying with the
Applicable Procedures in the case of the Global Notes) is a condition to receipt by the holder of the Fundamental Change Purchase Price therefor; provided, however, that such Fundamental Change Purchase Price shall be so paid pursuant
to this Section 14.01 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Fundamental Change Purchase Notice, as determined by the Company. 
 The Company shall purchase from the holder thereof, pursuant to this Section 14.01, a portion of a Note if the principal amount of such portion is
$1,000 or an integral multiple thereof. Provisions of the Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note. 
  


 71 








 A Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase
Notice or written withdrawal thereof. 
 Anything herein to the contrary notwithstanding, in the case of Global Notes, any Fundamental Change
Purchase Notice may be delivered or withdrawn and such Notes may be surrendered or delivered for purchase in accordance with the Applicable Procedures as in effect from time to time. 
 (d) Notwithstanding the foregoing provisions of this Section 14.01, the Company shall not be required to issue a Fundamental Change Purchase Notice
upon a Fundamental Change (i) if a third party issues a Fundamental Change Purchase Notice in the manner, at the times and otherwise in compliance with the requirements set forth in Section 14.01(b) applicable to a Fundamental Change
Purchase Notice made by the Company and otherwise complies with the provisions of this Article 14 as if it were the Company and purchases, and pays for, all Notes validly tendered and not withdrawn pursuant to such Fundamental Change Purchase Notice
and (ii) provided that if such third party fails to comply with any of the provisions of this Article 14, the Company shall as promptly as reasonably practicable deliver the Fundamental Change Purchase Notice in accordance with, and otherwise
comply with, all provisions of this Article 14. 
 Section 14.02. Effect of Fundamental Change Purchase Notice. 
 (a) Upon receipt by the Paying Agent of the Fundamental Change Purchase Notice specified in Section 14.01(c), the holder of the Note in respect of
which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified in the following paragraph) thereafter be entitled to receive the Fundamental Change Purchase Price with respect
to such Note. Such Fundamental Change Purchase Price shall be paid to such holder, subject to receipt of cash by the Paying Agent, promptly following the later of (i) the Fundamental Change Purchase Date with respect to such Note (provided the
conditions in Section 14.01(c) have been satisfied) and (ii) the time of book-entry transfer or delivery of such Note to the Paying Agent by the holder thereof in the manner required by Section 14.01(c). Notes in respect of which a
Fundamental Change Purchase Notice has been given by the holder thereof may not be converted pursuant to Article 13 on or after the date of the delivery of such Fundamental Change Purchase Notice unless such Fundamental Change Purchase Notice has
first been validly withdrawn as specified in the following paragraph. 
 (b) A Fundamental Change Purchase Notice may be withdrawn (in whole
or in part) by means of a written notice (which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Notes, may be delivered electronically or by other means in
accordance with the Applicable Procedures) of withdrawal delivered by the holder to the Paying Agent at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date (or such later time as may
be required by applicable law), specifying (i) the principal amount of the Note or portion thereof (which must be a principal amount of $1,000 or an integral multiple thereof) with respect to which such notice of withdrawal is being submitted,
(ii) if certificated Notes have 

  

 72 








 
been issued, the serial numbers of the withdrawn Notes, or if not certificated, such notice must comply with Applicable Procedures, and (ii) the
principal amount, if any, which remains subject to the Fundamental Change Purchase Notice. If a Fundamental Change Purchase Notice has been properly withdrawn pursuant to this Section 14.02(b) prior to the Fundamental Change Purchase Date, the
Company shall not be obligated to purchase those Notes so identified in such notice of withdrawal. 
 Section 14.03. Deposit of Fundamental Change
Purchase Price. 
 Prior to 10:00 a.m., New York City time, on the applicable Fundamental Change Purchase Date, the Company shall
irrevocably deposit with the Paying Agent an amount of cash (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Fundamental Change Purchase Price of all the Notes or portions thereof which are to be
purchased as of such Fundamental Change Purchase Date. 
 If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New
York City time, on the Business Day following the applicable Fundamental Change Purchase Date, cash sufficient to pay the Fundamental Change Purchase Price of any Notes for which a Fundamental Change Purchase Notice has been tendered and not
withdrawn pursuant to Section 14.02(b), then, on such Fundamental Change Purchase Date, such Notes shall cease to be outstanding and interest and Additional Interest, if any, on such Notes shall cease to accrue, whether or not book-entry
transfer of the Notes is made or whether or not such Notes are delivered to the Paying Agent, and the rights of the holders in respect thereof shall terminate (other than the right to receive the Fundamental Change Purchase Price and previously
accrued and unpaid interest (including Additional Interest) upon delivery or transfer of such Notes). 
 The Company shall make a Public
Notice of the aggregate principal amount of Notes purchased as a result of such Fundamental Change on or as soon as practicable after the Fundamental Change Purchase Date. 
 Section 14.04. Definitive Notes Purchased in Part. 
 Any Definitive Note that is to be purchased
only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
holder thereof or such holder’s attorney duly authorized in writing) and promptly after the Fundamental Change Purchase Date the Company shall execute and the Trustee shall authenticate and deliver to the holder of such Note, without charge, a
new Note or Notes, of any authorized denomination or denominations as may be requested by such holder, in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased.

 Section 14.05. Covenant to Comply With Securities Laws Upon Purchase of Notes. 
 When complying with the provisions of Article 14, and subject to any exemptions available under applicable law, the Company shall: 
 (a) if such offer or purchase constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any
successor provision thereto) under the Exchange Act at the time of such offer or purchase, (i) if applicable, comply with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the Exchange Act and (ii) file the related Schedule TO
(or any successor schedule, form or report) if required under the Exchange Act; and 
  

 73 








 (b) otherwise comply with all applicable federal and state securities laws so as to permit the rights and
obligations under this Article 14 to be exercised in the time and in the manner specified therein. 
 Section 14.06. Repayment to the Company.

 To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 14.03 exceeds the aggregate Fundamental
Change Purchase Price of the Notes or portions thereof which the Company is obligated to purchase as of the Fundamental Change Purchase Date then, promptly after the Fundamental Change Purchase Date, the Paying Agent shall return any such excess to
the Company together with interest, if any, thereon.

 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

hereunder, including under Section 2.05, Section 2.06, Section 2.07, Section 2.08 and Section 2.09, 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 6.09.

 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

(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. 
  

 76 








 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 6.02, Section 6.03, Section 6.04, Section 7.03 and this Section 15.10 shall be applicable to any authenticating agent. 
 Section 15.11. Execution in Counterparts. 
 This Indenture may be executed in any number of
counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 
 Section 15.12.

 The Company shall qualify this Indenture under the Trust Indenture Act in accordance with the terms and
conditions of the Registration Rights Agreement and shall pay all reasonable costs and expenses (including attorneys’ fees and expenses for the Company, the Trustee and the holders) incurred in connection therewith, including, but not limited

 Section 15.13.

Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will deliver a copy of such schedule

 [FORM OF REVERSE OF NOTE] 
 NETWORK EQUIPMENT TECHNOLOGIES, INC. 
 3.75% Convertible Senior Notes due 2014 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 3.75% Convertible Senior Notes due 2014 (herein called the
“Notes”), issued under and pursuant to an Indenture dated as of December 18, 2007 (herein called the “Indenture”), between the Company and U.S. Bank National Association (herein called the “Trustee”), to which
Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Notes. Additional
Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. To the extent permitted by applicable law, if any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. 
 Subject to certain exceptions, in case an Event of Default, as
defined in the Indenture, shall have occurred and be continuing, the principal of, and accrued and unpaid interest on, all Notes, may be declared, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to
the conditions provided in the Indenture. 
 The Company will pay cash amounts due in respect of the Notes in money of the United States that
at the time of payment is legal tender for payment of public and private debts. 
 The Indenture contains provisions permitting the Company
and the Trustee in certain circumstances, without the consent of the holders of the Notes, and in other circumstances, with the consent of the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding,
evidenced as provided in the Indenture, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the
rights of the holders of the Notes; provided, however, that no such supplemental indenture shall make any of the changes set forth in Section 9.02 of the Indenture, without the consent of each holder of an outstanding Note
affected thereby. Subject to certain exceptions, it is also provided in the Indenture that, prior to any declaration accelerating the maturity of the Notes, the holders of a majority in aggregate principal amount of the Notes at the time outstanding
may on behalf of the holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. Any such consent or waiver by the holder of this Note (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Note or such
other Notes. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional (i) to pay the principal of, and accrued and unpaid interest on, this Note, at the place, at the respective times, at the rate and in the lawful money herein prescribed and (ii) to
satisfy its Conversion Obligation in the manner prescribed in the Indenture. 
  

 A-8 








 The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and
integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations. 
 The Notes are not subject to redemption through the operation of any sinking fund. 
 Upon the occurrence of a Fundamental Change, the holder has the right, at such holder’s option, to require the Company to purchase all of such
holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Purchase Date at a price equal to one hundred percent (100%) of the principal amount of the Notes such holder
elects to require the Company to purchase, together with accrued and unpaid interest to but excluding the Fundamental Change Purchase Date; provided, however, that if a Fundamental Change Purchase Date occurs after a record date and on
or prior to the corresponding Interest Payment Date, the Company shall pay the full amount of accrued and unpaid interest and Additional Interest, if any, on such Interest Payment Date to the Noteholder of record at the close of business on the
corresponding Record Date and the Fundamental Change Purchase Price shall be equal to 100% of the principal amount of the Notes to be purchased. The Company or, at the written request of the Company, the Trustee shall mail to all holders of record
of the Notes a notice of the occurrence of a Fundamental Change and of the purchase right arising as a result thereof on or before the tenth (10th) Business Day after the occurrence of any Fundamental Change. 
 Subject to the provisions of the Indenture, the holder hereof has the right, at its option, at any time prior to the Maturity Date, to convert any Notes
or portion thereof which is $1,000 or an integral multiple thereof, into shares of Common Stock, together with cash in lieu of any fractional shares, in each case at the Conversion Rate specified in the Indenture, as adjusted from time to time as
provided in the Indenture, upon surrender of this Note, together with a Conversion Notice, a form of which is attached to the Note, as provided in the Indenture and this Note, to the Company at the office or agency of the Company maintained for that
purpose in New York, New York, or at the option of such holder, the Corporate Trust Office, and, unless the shares issuable on conversion are to be issued in the same name as this Note, duly endorsed by, or accompanied by instruments of transfer in
form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney. The initial Conversion Rate shall be 73.3689 shares for each $1,000 principal amount of Notes. No fractional shares of Common Stock will be issued upon
any conversion, but an adjustment in cash will be paid to the holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion. No adjustment shall
be made for dividends or any shares issued upon conversion of such Note except as provided in the Indenture. 
 Upon due presentment for
registration of transfer of this Note at the office or agency of the Company in New York, New York, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange thereof, subject
to the limitations provided in the Indenture, without charge except for any tax, assessments or other governmental charge imposed in connection therewith.

 The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note
Registrar may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment
hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any Paying Agent nor any other Conversion Agent nor any Note Registrar shall be
affected by any notice to the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Note. 
 No recourse for the payment of the principal of, or accrued and unpaid interest on, this Note, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any Indebtedness represented thereby, shall be had
against any incorporator, stockholder, employee, agent, officer, director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether
by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and
released. 
 Terms used in this Note and defined in the Indenture are used herein as therein defined. 
 Customary abbreviations may be used in the name of a holder or an assignee, such as TEN COM (=tenants in common), TENANT (=tenants by the entireties), JT
TEN (joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform gift to Minors Act).
