The performance criteria established by the Administrator may be based on any one of, or combination of, economic value added, market value added, achievement of individual or corporate objectives, or other measures of performance selected by the Administrator.  Partial achievement of the specified criteria may result in a payment or vesting corresponding to the degree of achievement as specified in the Award Agreement.  

(d)Acquisitions and Other Transactions.  The Administrator may issue Awards under the Plan in settlement, assumption or substitution for, outstanding awards or obligations to grant future awards in connection with the Company or a Related Entity acquiring another entity, an interest in another entity or an additional interest in a Related Entity whether by merger, stock purchase, asset purchase or other form of transaction.

(e)Deferral of Award Payment.  The Administrator may establish one or more programs under the Plan to permit selected Grantees the opportunity to elect to defer receipt of consideration upon an Award, satisfaction of performance criteria, or other event that absent the election would entitle the Grantee to payment or receipt of Shares or other consideration under an Award.  The Administrator may establish the election procedures, the timing of such elections, the mechanisms for payments of, and accrual of interest or other earnings, if any, on amounts, Shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral program.

12.NO EFFECT ON TERMS OF EMPLOYMENT/CONSULTING RELATIONSHIP

The Plan shall not confer upon any Grantee any right with respect to the Grantee's Continuous Service, nor shall it interfere in any way with his or her right or the Company's right to terminate the Grantee's Continuous Service at any time, with or without Cause.

13.NO EFFECT ON RETIREMENT AND OTHER BENEFIT PLANS

Except as specifically provided in a retirement or other benefit plan of the Company or a Related Entity, Awards shall not be deemed compensation for purposes of computing benefits or contributions under any retirement plan of the Company or a Related Entity, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of compensation.

14.GOVERNING LAW

The Plan shall be governed by the laws of the State of Nevada and the Federal laws of the United States applicable therein; provided, however, that any Award Agreement may provide by its terms that it shall be governed by the laws of any other jurisdiction as may be deemed appropriate by the parties thereto.

 14 

 Any Global Note 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 FINRA in order for the Notes to be tradable on the PORTAL Market or as may be required for the Notes to be tradable on any other
market developed for trading of securities pursuant to Rule 144A or required 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. 
 Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the Officers executing
the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant thereto
or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any
particular Notes are subject. 
 The Global Note shall represent such principal amount of the outstanding Notes as shall be specified therein
and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be increased or
reduced to reflect repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of the Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the
Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the holder of such Notes in accordance with this Indenture. Payment of principal, accrued and unpaid interest, and Additional Interest, if any,
on the Global Note shall be made to the holder of such Note on the date of payment, unless a record date or other means of determining holders eligible to receive payment is provided for herein. 
 The terms and provisions contained in the form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of this
Indenture and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 
 Section 2.03. Date and Denomination of Notes; Payments of Interest. The Notes shall be issuable in registered form without coupons in
denominations 

  

 15 

 
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. Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Interest Record Date with
respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest (including Additional Interest, if any) shall be payable at the office or agency of the Company maintained by the Company
for such purposes, which shall initially be the Corporate Trust office. The Company shall pay interest (including Additional Interest, if any) (a) on any Notes in certificated form (i) to Noteholders having an aggregate principal amount of
$5,000,000 or less, by check mailed to the Noteholders of these Notes, and (ii) to Noteholders having an aggregate principal amount of more than $5,000,000, either by check mailed to each Noteholder, or upon application by a Noteholder to the
Registrar not later than the relevant Interest Record Date, by wire transfer in immediately available funds to that Noteholder’s account within the United States, which application shall remain in effect until the Noteholder notifies, in
writing, the Registrar to the contrary or (b) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. 
 Any Defaulted Interest shall forthwith cease to be payable to the Noteholder on the relevant Interest Record Date by virtue of its 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: 
 (1) 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 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, 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 15 days and not less
than ten days prior to the date of the proposed payment, and not less than ten days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such special record date and the Trustee, in

  

 16 

 
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 its address as it appears in the Note Register, not less than ten 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 2.03. 
 (2) 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 2.04. Payments of Additional Interest. The Company shall make a one-time payment of Additional Interest in an amount equal to 50
basis points on the Notes (“Additional Interest”) if at any time during the six months to one year period following the original issuance date of the Notes, the Company fails to timely file any document or report that the Company is
required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable, other than reports on Form 8-K (the “Exchange Act Reports”); provided that the Company shall have 14 calendar days,
in the aggregate, to cure all such missed filings (the “Aggregate Cure Period”). The Additional Interest will be payable on the Interest Payment Date next following the first date during the six-month period as of which the Company
has not been current in filing its Exchange Act Reports during the prior twelve-month period (after giving effect to the Aggregate Cure Period). In addition to the payment of Additional Interest as set forth in this Section 2.04, the Company
may also elect to pay Additional Interest under the circumstances set forth in Section 7.01. 
 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 any of its Officers. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the 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; provided, however, that the Company may
issue Additional Notes only if: (1) such Additional Notes are fungible with the Initial Notes for 

  

 17 

 
U.S. federal income tax purposes, (2) the Additional Notes are issued with the same terms and with the same CUSIP number as the Initial Notes (except
that Additional Notes may have a different initial date from which interest begins to accrue thereon so that the Additional Notes are fungible with the Initial Notes), (3) the Additional Notes and the Initial Notes are treated as a single
series for all purposes under this Indenture, including, without limitation, with respect to waivers, amendments, voting rights, and offer to repurchase the Notes, and (4) the Trustee receives an Officers’ Certificate and an Opinion of
Counsel to the effect that such issuance of Additional Notes complies with the provisions of this Indenture, including each provision of this paragraph. 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 by an authorized officer of the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.11), 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. 
 Section 2.06. Exchange
and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The Company shall cause to be kept at the Corporate Trust office a register (the register maintained in such office or in any other office or agency of the
Company designated pursuant to Section 5.02 being herein sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall 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 5.02. 
 Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer 

  

 18 

 
set forth in this Section 2.06, the Company shall execute, and the Trustee shall upon receipt of a Company Order authenticate and deliver, in the name
of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. 
 Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be
exchanged at any such office or agency maintained by the Company pursuant to Section 5.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall upon receipt of a Company Order authenticate and
deliver, the Notes that 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, repurchase 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 (which may include signature guarantees) in form satisfactory to the Company and duly executed, by the Noteholder thereof or its 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 Company or the Trustee may require
payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection therewith as a result of the name of the Noteholder of the new Notes issued upon such exchange or registration of transfer of
Notes being different from the name of the Noteholder of the old Notes presented or surrendered for such exchange or registration of transfer. 
 None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such
portion thereof surrendered for conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 16 hereof. 
 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 

  

 19 

 
of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the 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) [Reserved.] 
 (d) Every Note that
bears or is required under this Section 2.06(d) to bear the legend set forth in this Section 2.06(d) (together with any Common Stock issued upon conversion of the Notes and required to bear the legend set forth in Section 2.06(e),
collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.06(d) (including the legend set forth below), unless such restrictions on transfer shall be eliminated or
otherwise waived by written consent of the Company, and the holder of each such Restricted Security, by such holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in Section 2.06(d) and
Section 2.06(e), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 
 Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the last date of original issuance of the Notes, or such other period of time
as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such later date, if any, as may be required by applicable laws, any certificate evidencing such Note (and all securities issued in exchange therefor
or substitution thereof, other than Common Stock, if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.06(e), if applicable) shall bear a legend in substantially the following form (unless such Notes have
been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, pursuant to the exemption from registration provided by Rule
144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee): 
 THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE
OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 
  

 20 

 (i) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED
INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 
 (ii) AGREES FOR THE BENEFIT OF KINETIC CONCEPTS, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE
TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY
SUCCESSOR PROVISION THEREUNDER, AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: 
 (A) TO
THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 
 (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE
SECURITIES ACT, OR 
 (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR

 (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE
EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE
(2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN
COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
  

 21 

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

  

 22 

 
principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee
such Global Note shall be canceled. 
 Definitive Notes issued in exchange for all or a part of the Global Note pursuant to this
Section 2.06(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and
authentication, the Trustee shall deliver such definitive Notes to the Persons in whose names such definitive Notes are so registered. 
 At
such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and instructions existing between
the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for definitive Notes, converted, canceled, repurchased or transferred to a transferee who receives definitive Notes therefor or
any definitive Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be
appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 
 None of the Company, the Trustee nor any agent of the Company or the Trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 (e) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of such Note shall bear a
legend in substantially the following form (unless the Note or such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the
time of such transfer or pursuant to the exemption from registration provided by Rule 144 under the Securities Act or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon conversion of Notes that
have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or pursuant to the exemption from registration provided by
Rule 144 under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent for the Common Stock):

 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 
 (i) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF
RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 
 (ii) AGREES FOR THE BENEFIT OF KINETIC CONCEPTS, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF
(X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THEREUNDER, AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY
APPLICABLE LAW, EXCEPT: 
 (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 
 (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 
 (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 
 (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE
COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR 

  

 24 

 
OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND
APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in
accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this
Section 2.06(e). 
 (f) Any Note or Common Stock issued upon the conversion or exchange of a Note that is purchased or owned by the
Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results
in such Notes or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144). 
 (g)
Notwithstanding any provision of Section 2.06 to the contrary, in the event Rule 144 as promulgated under the Securities Act (or any successor rule) is amended to change the one-year holding period thereunder (or the corresponding period under
any successor rule), from and after receipt by the Trustee of the Officers’ Certificate and Opinion of Counsel provided for in this Section 2.06(g), (i) each reference in Section 2.06(d) to “one year” and in the
restrictive legend set forth in such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period, (ii) each reference in Section 2.06(e) to “one year” and in the restrictive
legend set forth in such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period and (iii) all corresponding references in the Notes (including the definition of Resale Restriction
Termination Date) and the restrictive legends thereon shall be deemed for all purposes hereof to be references to such changed period, provided that such changes shall not become effective if they are otherwise prohibited by, or would
otherwise cause a violation of, the then-applicable federal securities laws. The provisions of this Section 2.06(g) will not be effective until such time as the Opinion of Counsel and Officers’ Certificate have been received by the Trustee
hereunder. This Section 2.06(g) shall apply to successive amendments to Rule 144 (or any successor rule) changing the holding period thereunder. 
  

 25 

 (h) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with
any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any
Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof. 
 (i) The Trustee shall not have any responsibility for any actions
taken or not taken by the Depositary. 
 Section 2.07. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its receipt of a Company Order 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 each of them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such
substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such
Note and of the ownership thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the
same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the holder of
a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been tendered for
repurchase upon a Fundamental Change or is about to be converted into cash and shares of Common Stock (or cash in lieu of such shares of Common Stock), if any, 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 each may be required by them to save each of them harmless for any loss, liability, cost or expense
caused by or 

  

 26 

 
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 2.07 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued
hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost
or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other
securities without their surrender. 
 Section 2.08. Temporary Notes. Pending the preparation of Notes in certificated form, the
Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon receipt of a Company Order, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized
denomination, and substantially in the form of the Notes in certificated form but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be
executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay the Company
will execute and deliver to the Trustee or such authenticating agent Notes in certificated form (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each
office or agency maintained by the Company pursuant to Section 5.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated
form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this
Indenture as Notes in certificated form authenticated and delivered hereunder. 
 Section 2.09. Cancellation of Notes Paid, Etc.
All Notes surrendered for the purpose of payment, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the Trustee
and promptly 

  

 27 

 
canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures. If the Company shall acquire any of the Notes, such acquisition shall not operate as satisfaction of the
indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 
 Section 2.10.
CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Noteholders as a convenience to 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 on such notice and that reliance may be placed only on the other identification numbers
printed on the Notes. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 Section 2.11. Repurchases. The Company and its Affiliates may from time to time repurchase the Notes in open market purchases or negotiated transactions without prior notice to Noteholders; provided that any Notes so
purchased may not be resold by the Company or any such Affiliate.

 ARTICLE 4 
 SATISFACTION AND DISCHARGE 
 Section 4.01. Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and
which have been replaced or paid as provided in Section 2.07 and (y) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged
from such trust, as provided in Section 5.04(d)) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to Noteholders, as applicable, after the Notes have become due and
payable, whether at the Maturity Date, any Fundamental Change Purchase Date, upon conversion or otherwise, cash or cash and shares of Common Stock, if any (solely to satisfy the Company’s 

  

 28 

 
obligation upon conversion, if applicable), sufficient to pay all of the outstanding Notes and all other sums due payable under this Indenture by the
Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have
been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 8.06 shall survive. 
 ARTICLE 5 
 PARTICULAR COVENANTS OF THE
COMPANY 
 Section 5.01. Payment of Principal, Interest and Additional Interest. The Company covenants and agrees
that it will cause to be paid the principal of, and accrued and unpaid interest and Additional Interest, if any, on each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. Each installment of
accrued and unpaid interest, and Additional Interest, if any, on the Notes due on any Interest Payment Date, may be paid by mailing checks for the amount payable to Noteholders entitled thereto as they shall appear on the registry books of the
Company; provided that, with respect to any Noteholder with an aggregate principal amount in excess of $5,000,000, at the application of such holder in writing to the Trustee and Paying Agent (if different from the Trustee) not later than the
relevant Interest Record Date, accrued and unpaid interest and Additional Interest, if any, on such holder’s Notes shall be paid by wire transfer in immediately available funds to such holder’s account in the United States, which
application shall remain in effect until the Noteholder notifies, in writing, the Trustee and Paying Agent to the contrary; provided, further, that payment of accrued and unpaid interest and Additional Interest, if any, made to the
Depositary shall be paid by wire transfer in immediately available funds in accordance with such wire transfer instructions and other procedures provided by the Depositary from time to time. 
 Section 5.02. 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 or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes
and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust office or another office or agency of the Trustee. 
  

 29 

 The Company may also from time to time designate as co-registrars one or more other offices or agencies
where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to
maintain an office or agency 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 as one such office or agency of the Company for each of the aforesaid purposes.

 Section 5.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a
vacancy in the office of Trustee, will appoint, in the manner provided in Section 8.10, a Trustee, so that there shall at all times be a Trustee hereunder. 
 Section 5.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an
instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.04: 
 (i) that
it will hold all sums held by it as such agent for the payment of the principal of and accrued and unpaid interest and Additional Interest, if any, on the Notes in trust for the benefit of the holders of the Notes; 
 (ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal of and accrued and
unpaid interest and Additional Interest, if any, on the Notes when the same shall be due and payable; and 
 (iii) that at any
time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 
 The Company shall, on or before each due date of the principal of, or accrued and unpaid interest or Additional Interest, if any, on the Notes, deposit with the Paying Agent a sum sufficient to pay such principal or accrued and unpaid
interest or Additional Interest, if any, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action, provided that if such deposit is made on the due date, such deposit must
be received by the Paying Agent by 11:00 a.m., New York City time, on such date. 
  

 30 

 (b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the
principal of, and accrued and unpaid interest and Additional Interest, if any, on the Notes, set aside, segregate and hold in trust for the benefit of the holders of the Notes a sum sufficient to pay such principal and accrued and unpaid interest
and Additional Interest, if any, so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal of and accrued and unpaid interest and
Additional Interest, if any, on the Notes when the same shall become due and payable. 
 (c) Anything in this Section 5.04 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 all sums held in trust by the Company or any Paying
Agent hereunder as required by this Section 5.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released
from all further liability with respect to such sums. 
 (d) Any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of and accrued and unpaid interest and Additional Interest, if any, on any Note and remaining unclaimed for two years after such principal, interest or Additional Interest has become due and payable
shall be paid to the Company on request of the Company contained in an Officers’ Certificate, or (if then held by the Company) shall be discharged from such trust; and the holder of such Note shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that
the Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of
general circulation in The Borough of Manhattan, The City of New York, New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty days from the date of such publication, any

 31 

 Section 5.06. Rule 144A Information Requirement and Annual Reports. (a) At any time the
Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities”
within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and shall, upon written request, provide to any holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issued upon
conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under the Securities Act. The Company
shall take such further action as any holder or beneficial owner of such Notes or such Common Stock may reasonably request to the extent required from time to time to enable such holder or beneficial holder to sell such Notes or shares of Common
Stock in accordance with Rule 144A under the Securities Act, as such rule may be amended from time to time. 
 (b) The Company shall deliver
to the Trustee within 15 days after the same is filed with the Commission, copies of the quarterly and annual reports and of the information, documents and other reports, if any, that the Company is required (giving effect to any grace period
provided by Rule 12b-25) to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, and the Company shall otherwise comply with the requirements of Trust Indenture Act section 314(a). Notwithstanding the provisions of
Section 17.08, any such information, documents or reports filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (or EDGAR) system shall be deemed to be delivered to the Trustee. 
 (c) Delivery of the reports, information and documents described in clause (b) above to the Trustee is for informational purposes only, and the
Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which
the Trustee is entitled to conclusively rely on an Officers’ Certificate). The Trustee has no responsibility to monitor the Company’s compliance with this Section 5.06(c). 
 Section 5.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time
insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the
Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such
law had been enacted. 
  

 32 

 Section 5.08. Compliance Certificate; Statements as to Defaults. The Company shall deliver to
the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2008) an Officers’ Certificate stating whether or not the signer thereof has knowledge of any failure by
the Company to comply with all conditions and covenants then required to be performed under this Indenture and, if so, specifying each such failure and the nature thereof. 
 In addition, the Company shall deliver to the Trustee, within 30 days after the Company becomes aware of the occurrence of any Event of Default or
Default, an Officers’ Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company proposes to take with respect thereto.

Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (a) the amount of such Additional Interest that is payable and (b) the date on which such interest is payable. Unless and until a Responsible Officer
of the Trustee receives at the Corporate Trust office such a certificate, the Trustee may assume without inquiry that no such 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 Officers’ Certificate setting forth the particulars of such payment. 
 Section 5.10.
Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this

the Notes and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, shall be immediately due and payable. This provision, however,
is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter
provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest and accrued and unpaid Additional Interest, if any, upon all Notes and the principal of any and all Notes that
shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest and accrued and unpaid Additional Interest, if any, (to the extent that payment of such interest is enforceable under
applicable law) and on such principal at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 8.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent
jurisdiction and (2) all existing Events of Defaults under this Indenture, other than the nonpayment of principal of and accrued and unpaid interest, including accrued and unpaid Additional Interest, if any, on Notes that shall have become due
solely by such declaration or acceleration, shall have been cured or waived pursuant to Section 7.07, then and in every such case the holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the
Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes (other than a Default or an Event of Default resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to
deliver, upon conversion, cash and shares of Common Stock (or cash in lieu of such shares of Common Stock), if any, due upon conversion) and rescind and annul such declaration and its consequences (other than a declaration or consequences, as the
case may be, resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, a combination of cash and shares of Common Stock, as applicable, due upon conversion) and such
Default (other than a Default resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as
applicable, due upon conversion) shall cease to exist, and any Event of Default arising therefrom (other than a Default resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver upon conversion
of Notes amounts owing upon conversion) shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall
impair any right consequent thereon. 
 Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company
shall so elect, for the first 180 days after an Event of Default relating to (1) the Company’s failure to file with the Trustee pursuant to 

  

 37 

 
Section 314(a)(1) of the Trust Indenture Act any documents or reports that the Company is required to file with the Commission pursuant to
Section 13 or 15(d) of the Exchange Act, or (2) the Company’s failure to comply with Section 5.06(b) of this Indenture, and the continuation thereof, the sole remedy for any such Event of Default shall be the accrual of
Additional Interest on the Notes at a rate per year equal to 0.50% of the outstanding principal amount of the Notes (provided that such Additional Interest shall be in addition to any Additional Interest payable pursuant to
Section 2.04), payable on or before the date on which such Event of Default occurs. On and after the 180th day (if the Event of Default relating to the failure to file the Exchange Act Reports as required by Section 2.04 is not cured or
waived prior to such 180th day), either the Trustee or the Noteholders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare the principal amount of the Notes and any accrued and unpaid interest, including any
Additional Interest, through the date of such declaration, to be immediately due and payable. In the event the Company does not elect to pay the Additional Interest upon an Event of Default in accordance with this paragraph, the Notes will be
subject to acceleration as otherwise provided in this Section 7.01. 
 In order to elect to pay the Additional Interest in accordance
with the immediately preceding paragraph, the Company must (1) notify in writing all Noteholders, the Trustee and Paying Agent of its election to pay Additional Interest on or before the close of business on the date on which the related Event
of Default occurs and (2) pay such Additional Interest on or before the close of business on the date on which the related Event of Default occurs. Upon the failure to timely give all Noteholders, the Trustee and Paying Agent such notice, the
Notes will be subject to acceleration as provided in this Section 7.01. 
 In case the Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the
Company, the Noteholders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Noteholders, and the
Trustee shall continue as though no such proceeding had been instituted. 
 Section 7.02. Payments of Notes on Default; Suit
Therefor. If an Event of Default described in clause (a) or (b) of Section 7.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the holders of the Notes, the whole amount then due
and payable on the Notes for principal, interest and Additional Interest, if any, with interest on any overdue principal, interest and Additional Interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further
amount as shall be sufficient to cover any amounts due to the Trustee under Section 8.06. If the Company shall 

  

 38 

 
fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for
the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 
 In the event there shall
be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings
relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 7.02, 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, accrued and unpaid interest and accrued and unpaid Additional Interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or
documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and of the Noteholders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or
deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 8.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official
is hereby authorized by each of the Noteholders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any
amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 8.06 hereof, incurred by it up to the date of such
distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be
paid out of, any and all distributions, dividends, monies, securities and other property that the holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or
otherwise. 
  

 39 

 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 7.03. Application of Monies Collected by Trustee. Any monies or property collected by the Trustee pursuant to this Article 7 with
respect to the Notes shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies or property, upon presentation of the several Notes, and stamping thereon the payment, if only partially
paid, and upon surrender thereof, if fully paid: 
 FIRST: to the payment of all amounts due the Trustee under Section 8.06; 

SECOND: in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on the Notes, including
Additional Interest, if any, in default in the order of the date due of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the rate borne
by the Notes at such time, such payments to be made ratably to the Persons entitled thereto; 
 THIRD: in case the principal of the
outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount including the payment of the Fundamental Change Purchase Price and, as a result of Section 15.04(g), any cash component of
the amounts owing upon 

  

 40 

 
conversion of the Notes, if any, then owing and unpaid upon the Notes for principal and interest, including Additional Interest, if any, with interest on the
overdue principal and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole
amounts so due and unpaid upon the Notes, then to the payment of such principal and interest, including Additional Interest, if any, 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: with respect to the remainder, if any, to the Company. 
 Section 7.04. 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 
 (a) such
holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, 
 (b) the holders of not less than 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder, 

(c) such holders shall have offered to the Trustee such security or indemnity satisfactory to it against any loss, liability or expense to be incurred
therein or thereby, 
 (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding and 
 (e) no direction that, in the opinion of the Trustee, is inconsistent with
such written request shall have been given to the Trustee by the holders of a majority in principal amount of the Notes outstanding within such 60-day period pursuant to Section 7.07; 
 it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee that no one or
more Noteholder shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Noteholder (it being understood that the Trustee does not have 

  

 41 

 
an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders), or to obtain or seek to obtain priority
over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Noteholders (except as otherwise provided herein). For the
protection and enforcement of this Section 7.04, 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 and accrued and unpaid Additional Interest, if any, on such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such
payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such Noteholder. 
 Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, in its own behalf and for its own benefit, may enforce, and may
institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein. 
 Section 7.05. 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 7.06.
Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07, all powers and remedies given by this Article 7 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative
and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in
this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of
any such Default or any acquiescence therein; and, subject to the provisions of Section 7.04, every power and remedy given by this Article 7 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Noteholders. 
  

 42 

 Section 7.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The
holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available
to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the
Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other holder or that would
involve the Trustee in personal liability. The Noteholders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 may on behalf of the Noteholders of all of the Notes waive
any past Default or Event of Default hereunder and rescind any such acceleration with respect to the Notes and its consequences except (i) a Default in the payment of accrued and unpaid interest, including accrued and unpaid Additional
Interest, if any, on, or the principal of, the Notes when due that has not been cured pursuant to the provisions of Section 7.01, (ii) a failure by the Company to deliver cash and shares of Common Stock (or cash in lieu of such shares of
Common Stock), if any, upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 11 cannot be modified or amended without the consent of each holder of an outstanding Note affected. Upon
any such waiver the Company, the Trustee and the holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right
consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 7.07, 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 7.08. Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, mail to all Noteholders as the
names and addresses of such holders appear upon the Note Register, notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case
of a Default in the payment of the principal of, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on, any of the Notes, including without limiting the generality of the foregoing any Default in the payment of any
Fundamental Change Purchase Price, then in any such event the Trustee shall be protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determine that the withholding of such notice is
in the interests of the Noteholders. 
  

 43 

 Section 7.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder
of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and
expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 7.09 (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 10% in principal amount of the Notes at the time outstanding determined in accordance with
Section 9.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of and accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on any Note on or after the due date expressed
or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 15. 
 ARTICLE 8 
 CONCERNING THE TRUSTEE 
 Section 8.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or
waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived) the Trustee
shall exercise such rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs;
provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the holders unless such holders have
offered to the Trustee indemnity or security satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 
 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly negligent
failure to act or its own willful misconduct, except that 
  

 44 

 (a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of
Default that may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and 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; 
 (b) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements
and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions
hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy
of any mathematical calculations or other facts stated therein); 
 (c) the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 
 (d) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the
Notes at the time outstanding determined as provided in Section 9.04 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Indenture; 
 (e) 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; 
 (f) 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;

 (g) 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; 
  

 45 

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

 46 

 (e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense
of the Company and shall incur no liability of any kind by reason of such inquiry or investigation; 
 (f) the Trustee may execute any of the
trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any 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) the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and
duties hereunder; and 
 (i) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or
titles of officers authorized at such time to take specified actions pursuant to this Indenture. 
 In no event shall the Trustee be liable
for any consequential, special, indirect or punitive loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of
action other than any such loss or damage caused by the Trustee’s willful misconduct or gross negligence. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a
Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or by any holder of the Notes. 
 Section 8.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate
of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes.

  

 47 

 
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. 
 Section 8.04. Trustee, Paying Agents, Conversion Agents or Registrar
May Own Notes. The Trustee, any Paying Agent, any Conversion Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying Agent,
Conversion Agent or Note Registrar. 
 Section 8.05. Monies to be Held in Trust. All monies received by the Trustee shall, until
used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under
no liability for interest on any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee. 
 Section 8.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services
rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will
pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the
reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its gross negligence, willful
misconduct or bad faith. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold
them harmless against, any loss, claim, damage, liability or expense incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent,
as the case may be, and to the extent arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the reasonable costs and expenses of defending themselves against any claim of
liability in the premises. The obligations of the Company under this Section 8.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior lien to which the
Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 7.03, funds held in trust herewith for the benefit of the holders of 

  

 48 

 
particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 8.06 shall not be subordinate to any other liability
or indebtedness of the Company (even though the Notes may be so subordinated). The obligation of the Company under this Section 8.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the
Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 8.06 shall extend to the officers, directors, agents and employees of
the Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any
authenticating agent incur expenses or render services after an Event of Default specified in Section 7.01(h) or Section 7.01(i) occurs, the expenses and the compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws. 
 Section 8.07. Officers’ Certificate as Evidence. Except
as otherwise provided in Section 8.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder,
such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall be full warrant to the
Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 
 Section 8.08.

the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to
be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
  

 49 

 Section 8.10. Resignation or Removal of Trustee. (a) The Trustee may at any time resign
by giving written notice of such resignation to the Company and by mailing notice thereof to the Noteholders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint
a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have
been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Noteholders, petition, at the
expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 7.09,
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. Any
resignation by, or removal of, the Trustee shall not be effective until a successor trustee has been appointed. 
 (b) In case at any time
any of the following shall occur: 
 (i) the Trustee shall fail to comply with Section 8.08 within a reasonable time
after written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six months, or 
 (ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 8.09 and shall fail to resign after written request therefor by the Company or by any such Noteholder, or 
 (iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
property shall be appointed, or any public Officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
 then, in any such case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order
of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.09, any Noteholder who has been a bona fide holder of a Note
or Notes for at least six months may, on behalf of himself 

  

 50 

 
and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c) The holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with Section 9.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed
appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Noteholder, upon the terms and conditions and otherwise as in
Section 8.10 (a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 
 (d) Any
resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11.

 Section 8.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 8.10 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.06, execute and deliver an instrument transferring to such successor trustee all the rights
and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights
and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of
holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 8.06. 
 No successor trustee shall
accept appointment as provided in this Section 8.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 8.08 and be eligible under the provisions of Section 8.09. 

 

 51 

 Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, each of the
Company and the successor trustee, at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Noteholders at their addresses as they shall appear on the Note
Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
 Section 8.12. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with which it
may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust
business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that
in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be qualified under the provisions of Section 8.08 and eligible under the
provisions of Section 8.09. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture,
any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver
such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of
any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall
have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation. 
 Section 8.13. Limitation on Rights of Trustee as Creditor. If and when the Trustee shall be or
become a creditor of the Company (or any other obligor upon the Notes), after qualification under the Trust Indenture Act, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the
Company (or any such other obligor). 
 Section 8.14. Trustee’s Application for Instructions from the Company. Any
application by the Trustee for written instructions from the Company (other 

  

 52 

 
than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the holders of the Notes under this
Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The
Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days
after the date any Officer that the Company has indicated to the Trustee should receive such application actually receives such application, unless any such Officer shall have consented in writing to any earlier date), unless, prior to taking any
such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 
 ARTICLE 9 
 CONCERNING
THE NOTEHOLDERS 
 Section 9.01. Action by Noteholders. Whenever in this Indenture it is
provided that the holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action),
the fact that at the time of taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent
or proxy appointed in writing, or (b) by the record of the Noteholders voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article 10, or (c) by a combination of such instrument
or instruments and any such record of such a meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of
such solicitation, a date as the record date for determining Noteholders entitled to take such action. The record date if one is selected shall be not more than 15 days prior to the date of commencement of solicitation of such action. 
 Section 9.02. Proof of Execution by Noteholders. Subject to the provisions of Section 8.01, Section 8.02 and Section 10.05,
proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Noteholders’ meeting shall be proved in the manner provided in Section 10.06. 
  

 53 

 Section 9.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating
agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be
overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of, and (subject to
Section 2.03) accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on such note, for conversion of such note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion
Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for monies payable upon any such note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against
the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the
provisions of this Indenture. 
 Section 9.04. Company-Owned Notes Disregarded. In determining whether the holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the
purposes of this Section 9.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company or a Person directly or indirectly controlling
or controlled by or under direct or indirect common control with the Company. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. The Company shall furnish
to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 8.01, the Trustee
shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 
  

 54 

 Section 9.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not
after) the evidencing to the Trustee, as provided in Section 9.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of
a Note that is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust office and upon proof of holding as provided in
Section 9.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and of any
Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of
transfer thereof.

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

any supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
  

 58

case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 
 It shall not be necessary
for the consent of the Noteholders under this Section 11.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. After an amendment under this
Indenture becomes effective, the Company shall mail to the holders a notice briefly describing such amendment. However, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the
amendment. 
 Section 11.03. Effect of Supplemental Indentures. Any supplemental indenture executed pursuant to the provisions of
this Article 11 shall comply with the Trust Indenture Act, as then in effect. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 11, this Indenture shall be and be deemed to be modified and amended in

 Subject to the provisions of Section 12.02, the Company shall not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its properties and assets to, another Person

 (a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a
Corporation organized and existing under the laws of the United States, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, executed and delivered to the

be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, conveyance or transfer (but not in the case of a lease of all or substantially all of the Company’s
property and assets), the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated
at any time thereafter and, except in the case of a lease of all or substantially all of the Company’s property and assets, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations and
covenants under this Indenture. 
 In case of any such consolidation, merger, conveyance, transfer or lease, such changes in phraseology and
form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 12.03. Opinion of
Counsel to Be Given Trustee. No merger, consolidation, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation,
merger, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 12. 
 ARTICLE 13 
 IMMUNITY
OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS 
 Section 13.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on any Note, nor for any claim
based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness
represented thereby, shall be had against any incorporator, 

  

 62 

 
stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of the Company or of any Successor Company, either
directly or through the Company or any Successor Company, 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 14 
 SUBSIDIARY GUARANTEE; SUBORDINATION 
 Section 14.01. The Guarantee; Subordination. Subject to the provisions of this Article, the Subsidiary Guarantor hereby irrevocably and
unconditionally guarantees on a subordinated basis, the full and punctual payment (whether at Maturity, upon a Fundamental Change or otherwise) of the principal of, and interest on, each Note (the “Subsidiary Guarantee”). Upon
failure by the Company to pay punctually any such amount, the Subsidiary Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner specified in this Indenture. The obligations of the Subsidiary Guarantor under its
Subsidiary Guarantee are junior and subordinated in right of payment to such Subsidiary Guarantor’s guarantee of the Senior Debt. Noteholders are required to exercise their remedies against the Company as set forth herein before they proceed
directly against the Subsidiary Guarantor. 
 Section 14.02. Subsidiary Guarantee Unconditional. The obligations of the
Subsidiary Guarantor hereunder are unconditional and absolute and, without limiting the generality of the foregoing, will not be released or discharged except as provided in Section 14.03 or Section 14.09. 
 Section 14.03. Discharge; Reinstatement. The Subsidiary Guarantor’s obligations hereunder will remain in full force and effect until the
principal of, and interest on, the Notes have been paid in full. The Subsidiary Guarantee with respect to a Note shall automatically terminate immediately prior to such Note’s conversion; provided, however, that if the Company
defaults with respect to the payment of principal in cash, the Subsidiary Guarantee shall be reinstated. If at any time any payment of the principal of, or interest on, any Note is rescinded or must be otherwise restored or returned upon the
insolvency, bankruptcy or reorganization of the Company or otherwise, the Subsidiary Guarantor obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time. 
 Section 14.04. Waiver by the Subsidiary Guarantor. The Subsidiary Guarantor irrevocably waives acceptance hereof, presentment, demand,
protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company or any other Person. 
  

 63 

 Section 14.05. Subrogation and Contribution. Upon making any payment with respect to any
obligation of the Company under this Article, the Subsidiary Guarantor making such payment will be subrogated to the rights of the payee against the Company with respect to such obligation. 
 Section 14.06. Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Company under this Indenture or the
Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of this Indenture are nonetheless payable by the Subsidiary Guarantor hereunder forthwith on demand
by the Trustee or the Noteholders. 
 Section 14.07. Limitation on Amount of Subsidiary Guarantee. Notwithstanding anything to
the contrary in this Article, the Subsidiary Guarantor, and by its acceptance of Notes, each Noteholder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Subsidiary Guarantor not constitute a
fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Noteholders and the Subsidiary Guarantor hereby
irrevocably agree that the obligations of the Subsidiary Guarantor under its Subsidiary Guarantee are limited to the maximum amount that would not render the Subsidiary Guarantor’s obligations subject to avoidance under applicable fraudulent
conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. 
 Section 14.08. Execution and
Delivery of Guarantee. The execution by the Subsidiary Guarantor of this Indenture evidences the Subsidiary Guarantee of such Subsidiary Guarantor, whether or not the person signing as an officer of the Subsidiary Guarantor still holds that
office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantor. 
 Section 14.09. Release of Subsidiary Guarantee. The Subsidiary Guarantee of the Subsidiary Guarantor will terminate upon: 
 (1) a sale or other disposition (including by way of consolidation or merger), in one transaction or a series of related transactions, of
a majority of the total voting power of the common stock or other interests of the Subsidiary Guarantor (other than to the Company or any of its affiliates); or 
  

 64 

 (2) the sale or disposition of all or substantially all the assets of the Subsidiary
Guarantor (other than to the Company or any of its affiliates); 
 (3) satisfaction and discharge of the Notes, as provided in
Article 4. 
 Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the foregoing effect, the Trustee
will execute any documents reasonably required in order to evidence the release of the Subsidiary Guarantor from its obligations under its Subsidiary Guarantee. 
 Section 14.10. Agreement to Subordinate. The Subsidiary Guarantee evidenced above is subordinated in right of payment, to the extent and in the manner provided in this Indenture, to the prior payment of
all Senior Debt; provided that for the avoidance of doubt, the Subsidiary Guarantee shall rank pari passu with all unsecured trade payables of the Subsidiary Guarantor. The subordination provisions are for the benefit of and
enforceable by the holders of Senior Debt. 
 Section 14.11. Liquidation, Dissolution, Bankruptcy. Upon any payment or
distribution of the assets of the Company to creditors upon a total or partial liquidation or a total or partial dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or
its property: 
 (1) holders of Senior Debt are entitled to receive payment in full in cash of all the Subsidiary
Guarantor’s obligations in respect of the Senior Debt, before Noteholders will be entitled to seek payment from the Subsidiary Guarantor under the Subsidiary Guarantee of the principal and interest payment obligations under the Notes; and

 (2) until the obligations of the Subsidiary Guarantor are satisfied in full in respect of the Senior Debt, any distribution
to which Noteholders would be entitled but for these subordination provisions shall instead be made to holders of the Senior Debt as their interests may appear. 
 Section 14.12. Default on Senior Debt. (a) The Subsidiary Guarantor shall not make any payment in respect of the Subsidiary Guarantee if at the time a default exists in the payment of any obligation
under the Senior Debt, and the default has not been cured or waived. 
 (b) During the continuance of any other default with respect to the
Senior Debt, the Subsidiary Guarantor may not make any payment under the Subsidiary Guarantee for a period (a “Payment Blockage Period”) 
  

 65 

 (1) commencing upon the receipt by the Subsidiary Guarantor and the Trustee of written
notice of default from the holders of the Senior Debt specifying an election to effect a Payment Blockage Period (a “Blockage Notice”) and 
 (2) ending 179 days thereafter (or earlier if the Payment Blockage Period is terminated (i) by written notice to the Trustee and the Subsidiary Guarantor from the entity that gave the Blockage Notice,
(ii) by payment in full of such obligation with respect to the Senior Debt or (iii) because the outstanding payment obligation giving rise to the Blockage Notice is no longer continuing). 
 Subject to the preceding paragraph, unless the holders of such Senior Debt have accelerated the maturity of such Senior Debt, the Subsidiary Guarantor may resume
payments on the Notes after the Payment Blockage Period. 
 (c) Not more than one Blockage Notice may be given in any consecutive 360-day
period, irrespective of the number of defaults with respect to Senior Debt during such period. No default which existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Senior Debt whose holders
initiated the Payment Blockage Period may be made the basis of the commencement of a subsequent Payment Blockage Period by the holders of such Senior Debt, whether or not within a period of 360 consecutive days, unless the default has been cured or
waived for a period of not less than 90 consecutive days. 
 Section 14.13. When Distribution Must Be Paid Over. If a payment or
other distribution is made to Noteholders that because of these subordination provisions should not have been made to them, the Noteholders that receive the distribution shall hold it in trust for holders of the Senior Debt and pay it over to them
as their interests may appear. 
 Section 14.14. Subrogation. A distribution made under these subordination provisions to holders
of Senior Debt which otherwise would have been made to Noteholders is not, as between the Subsidiary Guarantor and Noteholders, a payment by the Subsidiary Guarantor on the Senior Debt. After all of its obligations are satisfied under the Senior
Debt, Noteholders will be subrogated to the rights of holders of the Senior Debt to receive payments in respect of Senior Debt. Payments to holders of Senior Debt as a result of those provisions do not constitute, as between the Subsidiary Guarantor
and the Noteholders, payments by the Subsidiary Guarantor on the Notes. 
 Section 14.15. Relative Rights; Subordination Not to
Prevent Events of Default or Limit Right to Accelerate. These subordination provisions define the relative rights of Noteholders and holders of Senior Debt and do not impair, as 

  

 66 

 
between the Subsidiary Guarantor and Noteholders, the obligation of the Subsidiary Guarantor, which is absolute and unconditional, to perform its obligations
under the Subsidiary Guarantee with respect to the Notes in accordance with its terms. The failure to make a payment pursuant to the Notes by reason of these subordination provisions does not prevent the occurrence of a Default, nor do these
subordination provisions have any effect on the right of the Noteholders or the Trustee to accelerate the maturity of the Notes upon an Event of Default or prevent the Trustee or any Noteholder from exercising its available remedies upon a Default,
subject to the rights of holders of Senior Debt to receive distributions otherwise payable to Noteholders. 
 Section 14.16.
Subordination May Not Be Impaired By the Subsidiary Guarantor. No right of any holder of Senior Debt to enforce the subordination of the Subsidiary Guarantee will be impaired by any act or failure to act by the Subsidiary Guarantor or by its
failure to comply with the Indenture. 
 Section 14.17. Rights of Trustee. (a) The Trustee may continue to make payments on
the Notes and will not be charged with knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, the Trustee receives notice satisfactory to it
from the Subsidiary Guarantor or a holder of Senior Debt that payments may not be made under this Article. 
 (b) The Trustee in its
individual or any other capacity may hold Senior Debt with the same rights, including rights under this Article, it would have if it were not Trustee. Nothing in this Article applies to claims of, or payments to, the Trustee under or pursuant to
Section 8.06. 
 Section 14.18. Distributions and Notices to, and Notices and Consents by, Representatives of Holders of Senior
Debt. Whenever a distribution is to be made or a notice given to holders of Senior Debt, the distribution may be made and the notice given to their representative (if any). If there is a representative acting for the holders of any Senior Debt
pursuant to the agreements governing such Senior Debt, notices or consents under this Indenture from holders of such Senior Debt may be given only by their representative. 
 Section 14.19. Trust Moneys Not Subordinated. Notwithstanding anything to the contrary, payments from money or other obligations held by the
Trustee in trust under Article 4 are not subordinated to the prior payment of any Senior Debt or otherwise subject to these subordination provisions, and none of the Noteholders will be obligated to pay over any such payments or distributions to any
holder of Senior Debt. 
 Section 14.20. Trustee Entitled to Rely. For the purpose of ascertaining the outstanding amount of
Senior Debt, the holders thereof, and all other 

  

 67 

 
information relevant to making any payment or distribution to holders of Senior Debt pursuant to this Article, the Trustee and the Noteholders are entitled
to conclusively rely upon an order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 14.11 are pending, a certificate of the liquidating trustee or other Person making a payment or
distribution to the Trustee or to the Noteholders, or information provided by the holders of Senior Debt. The Trustee may defer any payment or distribution pending receipt of evidence or instructions satisfactory to it or a judicial determination
regarding the rights of parties to receive the payment or distribution. 
 Section 14.21. Trustee to Effectuate Subordination.
Each Noteholder by accepting a Note authorizes and directs the Trustee on behalf of the Noteholder to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination of the Subsidiary Guarantee to the Senior
Debt as provided in this Article and appoints the Trustee as attorney-in-fact for any and all such purposes, including for the purpose of filing a claim in any proceedings of the nature referred to in Section 14.11. 
 Section 14.22. Trustee Not Fiduciary for Holders of Senior Debt. The Trustee will not be deemed to owe any fiduciary duty to the holders of
Senior Debt and will not be liable to any such holders if it mistakenly pays over or distribute to Noteholders, or to the Company or any other Person, any money or assets to which holders of Senior Debt are entitled by virtue of this Article.

 Section 14.23. Reliance by Holder of Senior Debt on Subordination Provisions; No Waiver. (a) Each Noteholder by accepting
a Note acknowledges and agrees that these subordination provisions are, and are intended to be, an inducement and a consideration to each holder of Senior Debt, whether created or acquired before or after the issuance of the Notes, to acquire or to
hold such Senior Debt, and each holder of Senior Debt will be deemed conclusively to have relied on these subordination provisions in acquiring and holding such Senior Debt. 
 (b) The holders of Senior Debt may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Notes,
without incurring any liability or responsibility to the Holders of the Notes, and without impairing the rights of holders of Senior Debt under these subordination provisions, do any of the following: 
 (1) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Debt or any instrument
evidencing the same or any agreement under which Senior Debt is outstanding or secured; 
  

 68 

 (2) sell, exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Debt; 
 (3) release any Person liable in any manner for the payment of Senior Debt; or 

(4) exercise or refrain from exercising any rights against the Company and any other Person. 
 ARTICLE 15 
 CONVERSION
OF NOTES 
 Section 15.01. Conversion Privilege. (a) Upon compliance with the provisions of
this Article 15, a Noteholder shall have the right, at such holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction
of the conditions described in Section 15.01(b) below, at any time prior to the close of business on the Business Day immediately preceding October 15, 2014 under the circumstances and during the periods set forth in Section 15.01(b)
below, and (ii) irrespective of the conditions described in Section 15.01(b) below, on or after October 15, 2014, and prior to the close of business on the third Scheduled Trading Day immediately preceding the Maturity Date, in each
case, at an initial conversion rate (the “Conversion Rate”) of 19.4764 shares of Common Stock (subject to adjustment as provided in Section 15.04 of this Indenture) per $1,000 principal amount of Notes. 
 (b) (i) The Notes may be surrendered for conversion during the five Business Day period immediately after any five consecutive Trading Day period (the
“Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Noteholder in accordance with this paragraph, for each day of such Measurement Period was less than 98% of
the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. The Trading Prices shall be determined by the Trustee pursuant to this clause and the definition of Trading Price set forth in this Indenture. The
Company shall provide written notice to the Trustee of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The
Trustee shall have no obligation to determine the Trading Price of the Notes unless requested in writing by the Company, and the Company shall have no obligation to make such request unless a Noteholder provides the Company with reasonable evidence
that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate, at which time the Company shall instruct the Trustee to
determine the Trading Price 

  

 69 

 
of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the Notes is greater
than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and applicable Conversion Rate on such Trading Day. If the Trading Price condition set forth above has been met, the Company shall notify Noteholders in
accordance with the provisions of this Indenture. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the applicable
Conversion Rate and the Last Reported Sale Price of the Common Stock on such Trading Day, the Company shall so notify the Noteholders, the Trustee and the Conversion Agent. In either case, the Company shall promptly publish a notice indicating that
the Trading Price condition set forth above has been met or, at any time after the Trading Price condition set forth above has been met, that the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of the applicable
Conversion Rate and the Last Reported Sale Price of the Common Stock on the relevant Trading Day, as the case may be, on its website, by posting such information through the facilities of the Depositary or through such other public medium as the
Company may elect to use at that time. 
 (ii) In the event that the Company elects to: 
 (A) issue to all or substantially all holders of Common Stock any rights or warrants entitling them for a period of not more than 60
calendar days from the declaration date of such distribution to subscribe for or purchase shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of a share of Common Stock for the 10 consecutive Trading
Day period ending on the Trading Day immediately preceding the date of announcement of such issuance; or 
 (B) distribute to
all or substantially all holders of Common Stock the Company’s assets, debt securities or certain rights to purchase securities of the Company, which distribution has a per share value (as reasonably determined by the Board of Directors)
exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of declaration for such distribution, 
 then, in each case, the Company shall notify all Noteholders, the Trustee and the Conversion Agent, not less than 48 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution. Once the Company has
given such notice, the Notes may be surrendered for conversion at any time until the earlier of (1) the close of business on the Business Day immediately prior to such Ex-Dividend Date or (2) the Company’s 

  

 70 

 
announcement that such issuance or distribution will not take place, even if the Notes are not otherwise convertible under this Section 15.01 at such
time. Notwithstanding the foregoing, no Noteholder may convert its Notes pursuant to this Section 15.01(b)(ii), and the Company shall not be required to deliver such notice, if such Noteholder is able to participate (as a result of holding the
Notes, and at the same time as Common Stock holders participate) in such issuance or distribution as if such Noteholder held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount of Notes held
by such Noteholder, divided by 1,000, without having to convert its Notes. 
 (iii) If a transaction or event that constitutes
a Fundamental Change or a Make-Whole Fundamental Change occurs, regardless of whether a Noteholder has the right to require the Company to repurchase the Notes in accordance with Article 16 hereof, or if the Company is a party to a consolidation,
merger, binding share exchange, or transfer or lease of all or substantially all of its assets (provided that the Notes shall not become convertible by reason of a consolidation, merger or other transaction effected with one of the Company’s
direct or indirect Subsidiaries for the sole purpose of changing the state of incorporation or organization of the Company to any other state within the United States or the District of Columbia), pursuant to which the Common Stock would be
converted into cash, securities or other assets, a Noteholder may surrender its Notes for conversion at any time from or after the effective date of such transaction until 35 Trading Days after such effective date or, if such transaction also
constitutes a Fundamental Change, until the related Fundamental Change Purchase Date. The Company shall give notice to the Trustee and Noteholders as promptly as practicable following the date the Company publicly announces such transaction but in
no event less than five Scheduled Trading Days after the effective date of such transaction. If the transaction is a Make-Whole Fundamental Change, the Company shall state in such notice that in connection with such Make-Whole Fundamental Change,
the Company shall increase, in accordance with Section 15.03, the Conversion Rate applicable to Notes entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods during
which Notes must be surrendered in order to be entitled to such increase). 
 (iv) The Notes may be surrendered for conversion
during any Fiscal Quarter commencing after June 30, 2008, and only during such Fiscal Quarter, if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days in a period of 30 consecutive Trading Days ending on the last
Trading Day of the immediately preceding Fiscal Quarter is greater than or equal to 130% of the applicable Conversion Price on each applicable Trading Day. The Conversion Agent, on behalf of the Company, 

  

 71 

 
shall determine at the beginning of each Fiscal Quarter commencing after June 30, 2008, whether the Notes may be surrendered for conversion in
accordance with this clause (iv) and shall notify the Company and the Trustee in accordance with the provisions of this Indenture. 
 Section 15.02. Conversion Procedure.  
 (a) [Reserved]. 
 (b) Upon conversion, in respect of each $1,000 principal amount of Notes being converted, the Company shall deliver a “Settlement
Amount” equal to the sum of the Daily Settlement Amounts for each of the 40 Trading Days during the Observation Period. The payment upon conversion shall be determined as follows. The Company shall also deliver to each converting Noteholder
cash in lieu of fractional shares of Common Stock, if any, as set forth in clause (k) below. The Company shall deliver the sum of the Daily Settlement Amounts for each of the 40 Trading Days during the Observation Period to converting
Noteholders on the third Business Day immediately following the last day of the Observation Period. 
 (c) Before any Noteholder of a Note
shall be entitled to convert the same as set forth above, such Noteholder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to the interest payable on
the next Interest Payment Date to which such Noteholder is not entitled as set forth in Section 15.02(j) and, if required, all taxes or duties, if any, and (ii) in the case of a Note issued in certificated form, (1) complete and
manually sign the conversion notice on the back of the Note, or a facsimile thereof (a “Notice of Conversion”), (2) deliver the Notice of Conversion, which shall be irrevocable, to the Conversion Agent at the office of the
Conversion Agent and shall state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Noteholder wishes the certificate or certificates for any shares of Common Stock to be delivered
upon settlement of the amounts owing upon conversion of the Notes to be registered, (3) if required, furnish appropriate endorsements and transfer documents, (4) if required, pay all transfer or similar taxes, if any, as set forth in
Section 15.02(g), (5) if required, pay funds equal to the interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 15.02(j) and (6) surrender such Notes, duly endorsed to the
Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent. The Trustee (and if different, the relevant Conversion Agent) shall notify the Company of any conversion pursuant to this
Article 15 on the date of such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a holder thereof if such Noteholder has also delivered a Fundamental Change Purchase Notice to the Company in respect of such Notes
and not validly withdrawn such Fundamental Change Purchase Notice in accordance with Section 16.03. 
  

 72 

 If more than one Note shall be surrendered for conversion at one time by the same Noteholder, the
aggregate amounts of cash and shares of Common Stock, if any, owing upon conversion with respect to such Notes that shall be payable upon such 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. 
 (d) A Note shall be deemed to have been converted immediately prior to
the close of business on the date (the “Conversion Date”) that the holder has complied with the requirements set forth in clause (c). If any shares of Common Stock are due to converting Noteholders, the Company shall issue or cause
to be issued, and deliver to the Conversion Agent or to such noteholder, or such noteholder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock to which such
noteholder shall be entitled in satisfaction of the amounts owing upon conversion. 
 (e) In case any Note shall be surrendered for partial
conversion, the Company shall execute and the Trustee upon receipt of a Company Order shall authenticate and deliver to or upon the written order of the holder of the Note so surrendered, without charge to such holder, a new Note or Notes in
authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note. 
 (f) If a holder
submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due that may be imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the
issuance of shares of Common Stock, if any, upon the conversion. However, the Noteholder shall pay any such tax that is due because the holder requests any shares of Common Stock to be issued in a name other than such Noteholder’s name. The
Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the holder’s name until the Trustee receives a sum sufficient to pay any tax that will be due because the shares
are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations. 
 (g) Except as provided in Section 15.04, no adjustment shall be made for dividends on any shares issued upon the conversion of any Note as provided in this Article. 
 (h) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such
Global 

  

 73 

 
Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected
through any Conversion Agent other than the Trustee. 
 (i) Upon conversion, a Noteholder shall not receive any separate cash payment for
accrued and unpaid interest or Additional Interest, if any, except as set forth below. The Company’s delivery of the amounts owing upon conversion as described herein shall be deemed to satisfy its obligation to pay the principal amount of the
Note and accrued and unpaid interest, including 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 an Interest Record Date, holders of such notes as of the close of business on
the Interest Record Date will receive the interest and Additional Interest, if any, payable on such notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes, upon surrender for conversion during the period from the
close of business on any Interest Record Date to the opening of business on the corresponding Interest Payment Date, must be accompanied by funds equal to the amount of interest and Additional Interest, if any, payable on the Notes so converted;
provided, that no such payment shall be required (1) for Notes surrendered for conversion after the close of business on the Interest Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental
Change Purchase Date that is after an Interest Record Date and on or prior to the third Trading Day after the corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest exists 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, if any, on converted Notes. 
 (j) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of
record as of the close of business on the last Trading Day of the related Observation Period; provided, however, that if such last Trading Day of the Observation Period occurs on any date when the stock transfer books of the Company
shall be closed, such occurrence shall not be effective to constitute the Person or Persons entitled to receive any such shares of Common Stock due upon conversion as the record holder or holders of such shares of Common Stock on such date, but such
occurrence shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock
transfer books are open. Upon conversion of Notes, such Person shall no longer be a Noteholder. 
  

 74 

 (k) For each Note surrendered for conversion, the number of full shares that shall be issued upon
conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Observation Period and any fractional shares remaining after such computation shall be paid in cash. If more than one Note shall be
surrendered for conversion at one time by the same holder, the number of full shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so
surrendered. The Company shall not issue fractional shares of Common Stock upon conversion of Notes. Instead, the Company shall pay cash in lieu of fractional shares based on the Daily VWAP for the final Trading Day of the relevant Observation
Period. 
 (l) Notwithstanding the provisions described above in subsections (b) and (c), in satisfaction of the Company’s
conversion obligation, the Company may, at its election (the “Exchange Election”) direct the Conversion Agent to surrender, on or prior to the second Business Day following the relevant Conversion Date, such Notes to a financial
institution designated by the Company for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated institution must agree to timely deliver, in exchange for such Notes, the cash and/or shares, if any,
of Common Stock that would otherwise be due upon conversion as described herein. If the Company makes an Exchange Election, the Company shall, by the close of business on the second Business Day following the relevant Conversion Date, notify, in
accordance with the procedures set forth herein, the Holder surrendering Notes for conversion that the Company has made the Exchange Election and shall notify the designated financial institution of the relevant deadline for delivery of the
conversion consideration. If the designated institution accepts any such Notes, it shall deliver the appropriate amount of cash and number of shares of Common Stock, if any, in accordance with Section 15.02(b). Any Notes exchanged by the
designated institution shall remain outstanding. If the designated institution agrees to accept any Notes for exchange but does not timely deliver the related consideration, or if such designated financial institution does not accept the Notes for
exchange, the Company shall, no later than the third Business Day immediately following the last day of the relevant Observation Period, deliver the consideration it would otherwise be required to deliver pursuant to the provisions of
Section 15.02(b). 
 Section 15.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with
Make-Whole Fundamental Changes. (a) Notwithstanding anything herein to the contrary, the Conversion Rate applicable to each Note that is surrendered for conversion, in accordance with this Article 15, at any time from and after the
Effective Date of the Make-Whole Fundamental Change up to, and including, the close of business on the Business Day immediately prior to the related Fundamental Change Purchase Date (or, in the case of an event that would have been a Fundamental
Change but for proviso (ii) in the second clause of the definition thereof, the 35th Trading Day immediately 

  

 75 

 
following the Effective Date of such Make-Whole Fundamental Change), shall be increased to an amount equal to the Conversion Rate that would, but for this
Section 15.03, otherwise apply to such Note pursuant to this Article 15, plus an amount equal to the Make-Whole Conversion Rate Adjustment. 
 As used herein, “Make-Whole Conversion Rate Adjustment” shall mean, with respect to a Make-Whole Fundamental Change, the amount, if any, by which the Conversion Rate per $1,000 principal amount of Notes shall increase as
set forth in the following table for each Stock Price and effective date of such Make-Whole Fundamental Change (the “Effective Date”):

 provided, however, that: 
 (i) if the Stock Price is between two Stock Price amounts in the table above or the Effective Date is between two Effective Dates listed
in the table above, then the Make-Whole Conversion Rate Adjustment for such Make-Whole Fundamental Change shall be determined by a straight-line interpolation between the Make-Whole Conversion Rate Adjustment set forth for such higher and lower
Stock Price amounts, or for such earlier and later Effective Dates, as applicable, based on a 365-day year; 
 (ii) if the
Stock Price is greater than $280.00 per share (subject to adjustment in the same manner as the Stock Price as provided in clause (iii) below), or if the Stock Price is less than $40.27 per share (subject to adjustment in the same manner as the
Stock Price as provided in clause (iii) below), then the Make-Whole Conversion Rate Adjustment shall be equal to zero and this Section 15.03 shall not require the Company to increase the Conversion Rate with respect to such Make-Whole
Fundamental Change; 
 (iii) if an event occurs that requires, pursuant to this Article 15 (other than solely pursuant to this
Section 15.03), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each Stock Price set forth in the column headings in 

  

 76 

 
the table above shall be adjusted so that such Stock Price, at and after such time, shall be equal to the product of (1) such Stock Price as in effect
immediately before such adjustment to such Stock Price and (2) a fraction whose numerator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be in effect,
in accordance with this Article 15, immediately after such adjustment to the Conversion Rate; 
 (iv) each Make-Whole
Conversion Rate Adjustment set forth in the table above shall be adjusted in the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted pursuant to Section 15.04; and 
 (v) in no event will the product of (x) the Conversion Rate (reflecting the increase, if any, pursuant to the Make-Whole Conversion
Rate Adjustment) and (ii) the aggregate principal amount of Notes issued under this Indenture, divided by 1,000, exceed the Aggregate Share Cap (subject to adjustments in the same manner as the Conversion Rate pursuant to Section 15.04).

 (b) No later than the actual Effective Date of a Make-Whole Fundamental Change, the Company shall mail to each Noteholder, the Trustee and
the Conversion Agent written notice of, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the Company’s website, such Effective Date and the
amount by which the Conversion Rate has been so increased. This notice shall be in addition to the notice required by Section 15.01(b)(iii). 
 (c) Nothing in this Section 15.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 15.04 in respect of a Make-Whole Fundamental Change. 
 Section 15.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows: 

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on shares of Common Stock, or if the Company effects a share
split or share combination, the Conversion Rate will be adjusted based on the following formula: 
  

																															
		 		 		 		 		 		 		 	 CR1 = CR0 x
	 	   OS1  
	 		 		 		 		 		 		 	
	 	 	 	 	 	 	 	 	  OS0  	 		 		 		 		 		 		 	

  

 77 

 where 
  

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

 Any adjustment made pursuant to this Section 15.04(a) shall become effective immediately after the opening of
business on the Ex-Dividend Date for such dividend or distribution, or the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 15.04(a) is declared but
not so paid or made, or the outstanding shares of Common Stock are not split or combined, as the case may be, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or
distribution, or to effect such split or combination, as the case may be, to the Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared or announced. 
 (b) If the Company issues to all or substantially all holders of its Common Stock any rights or warrants entitling them for a period of not more than 60
calendar days from the declaration date of such distribution to subscribe for or purchase 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 10 consecutive Trading Day
period ending on the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be adjusted based on the following formula: 
  

																															
		 		 		 		 		 		 		 	 CR1 = CR0 x
	 	   OS0 + X   
	 		 		 		 		 		 		 	
	 	 	 	 	 	 	 	 	  OS0 + Y  	 		 		 		 		 		 		 	

 where 
  

			
	 CR0 =
	  	the Conversion Rate in effect immediately prior to the Ex-Dividend Date for such issuance;

  

 78 

			
	 CR1 =
	  	the Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date;
		
	 OS0 =
	  	the number of shares of the Common Stock outstanding immediately prior to such Ex-Dividend Date;
		
	 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 the Common Stock over
the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of the issuance of such rights or warrants.

 The foregoing adjustment shall be successively made whenever any such rights or warrants are
distributed and shall become effective immediately after the opening of business on the Ex-Dividend Date for such distribution. The Company shall not issue any such rights or warrants in respect of shares of the Common Stock held in treasury by the
Company. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such Ex-Dividend Date for such distribution had not been fixed. In addition, to the extent
that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or
warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. 
 In determining whether any
rights or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock, and in determining the aggregate offering price of such shares of the
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. In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(b) (subject to the right of the Company to readjust the Conversion Rate as described in the immediately preceding paragraph). 

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of its or rights or warrants to
acquire Capital Stock or other securities, to all or substantially all holders of its Common Stock, excluding (i) dividends or distributions covered by Section 15.04(a) or 

  

 79 

 
Section 15.04(b), (ii) dividends or distributions paid exclusively in cash; and (iii) Spin-Offs to which the provisions set forth below in
this Section 15.04(c) shall apply (any of such shares of Capital Stock, indebtedness, other asset or property or rights or warrants to acquire Capital Stock or other securities hereinafter in this Section 15.04(c) called the
“Distributed Property”), then the Conversion Rate shall be adjusted based on the following formula: 
  

					
	CR1 = CR0 ×	  	 SP0
	  	
	  	SP0 – FMV	  	

 where 
  

			
	 CR0 =
	  	the Conversion Rate in effect immediately prior to the Ex-Dividend Date for such distribution;
		
	 CR1 =
	  	the Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date;
		
	 SP0 =
	  	the average of the Last Reported Sale Prices of the Common Stock over the 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 shares of Capital Stock, evidences of indebtedness, assets, property, rights or warrants distributed with respect to
each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution;

 provided that if “FMV” as set forth above
is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each
Noteholder shall receive on the date on which the Distributed Property is distributed to holders of Common Stock, for each $1,000 principal amount of Notes, the amount of Distributed Property such holder would have received had such holder owned a
number of shares of Common Stock equal to the Conversion Rate on the Record Date for such distribution, provided, further, that if the Board of Directors determines “FMV” for purposes of this Section 15.04(c) by
reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the ten consecutive
Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution. 
 An adjustment pursuant to
the immediately preceding paragraph shall become effective immediately prior to the opening of business on the Ex-Dividend 

  

 80 

 
Date for such distribution; provided that if such distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the
Conversion Rate that would then be in effect if such distribution had not been declared; provided, further, that in the case of Distributed property consisting of rights and warrants, the Conversion Rate shall be readjusted to the
extent that such rights or warrants are not exercised prior to their expiration. 
 With respect to an adjustment pursuant to this
Section 15.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the
Company (a “Spin-Off”), the Conversion Rate will be increased based on the following formula: 
  

					
	CR1 = CR0 x	  	 FMV0 + MP0
	  	
	  	MP0	  	

 where 
  

			
	 CR0 =
	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
		
	 CR1 =
	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
		
	 FMV0 =
	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock over the
first 10 consecutive Trading Day period after, and including, the effective date of the Spin-Off (the “Valuation Period”); and
		
	 MP0 =
	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph will occur on the last day of
the Valuation Period; provided that in respect of any conversion during the Valuation Period, references with respect to 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 Conversion Date in determining the applicable Conversion Rate. 
 Subject in all respect to Section 15.10,
rights, options or warrants distributed by the Company to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under
certain circumstances), which rights, options or warrants, until the occurrence of a specified event or 

  

 81 

 
events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and
(iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.04 (and no adjustment to the Conversion Rate under this Section 15.04 will be
required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this
Section 15.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or
warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to
new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of
rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate
under this Section 15.04 was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final
redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with
respect to such rights, options or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options or
warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of this Section 15.04(c), Section 15.04(a), and Section 15.04(b), any dividend or distribution to which this
Section 15.04(c) is applicable that also includes shares of Common Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock to which Section 15.04(a) or 15.04(b) (or both) applies, shall be deemed instead
to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights, options or warrants to which Section 15.04(c) applies (and any Conversion Rate
adjustment required by this Section 15.04(c) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights, options or warrants (and
any further Conversion Rate 

  

 82 

 
adjustment required by Section 15.04(a) and Section 15.04(b) with respect to such dividend or distribution shall then be made), except (A) the
Ex-Dividend Date of such dividend or distribution shall be substituted as “the Ex-Dividend Date” within the meaning of Section 15.04(a) or Section 15.04(b) (or both), as the case may be, and (B) any shares of Common Stock
included in such dividend or distribution shall not be deemed “outstanding immediately prior to such Ex-Dividend Date or the effective date” within the meaning of Section 15.04(a) or “outstanding immediately prior to such
Ex-Dividend Date” within the meaning of Section 15.04(b). 
 If any dividend or distribution described in this 15.04(c) is not so
paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. In no event will the Conversion Rate be decreased pursuant to the adjustments
described in this 15.04(c) (subject to the Company’s right to readjust the Conversion Rate as described in the immediately preceding sentence). 
 (d) If the Company pays any cash dividend or distribution to all or substantially all holders of its Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  

					
	CR1 = CR0 x	  	 SP0
	  	
	  	SP0 – C	  	

 where 
  

			
	 CR0=
	  	the Conversion Rate in effect immediately prior to the Ex-Dividend Date for such dividend or distribution;
		
	 CR1 =
	  	the Conversion Rate in effect immediately after the opening of business on the Ex-Dividend Date for such dividend or distribution;
		
	 SP0 =
	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
		
	 C =
	  	the amount in cash per share the Company distributes to holders of its Common Stock;

 provided that if “C” as set forth above is
equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each
Noteholder shall have the right to receive on the date on which the relevant cash dividend or distribution is distributed to holders of Common Stock, for each $1,000 principal amount of Notes, the amount of cash such holder would have received had
such holder owned a number of shares equal to the Conversion Rate on the Record Date for such distribution. 
  

 83 

 The adjustment to the Conversion Rate under the preceding paragraph will become effective immediately
after the opening of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared. 
 For the avoidance of doubt, for purposes of this Section 15.04(d), in the event
of any reclassification of the Common Stock, as a result of which the Notes become convertible into more than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant to this Section 15.04(d), references in this
Section to one share of Common Stock or Last Reported Sale Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Notes are then
convertible equal to the numbers of shares of such class issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications. 
 (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock, to the extent the cash
and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock on the 10 consecutive Trading Day period commencing on, and including, the Trading Day next
succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  

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

 where 
  

			
	 CR0=
	  	the Conversion Rate in effect at the close of business on the last Trading Day of the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date
such tender offer or exchange offer expires;
		
	 CR1 =
	  	the Conversion Rate in effect on the Business Day following the last Trading Day of the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the
date such tender or exchange offer expires;

  

 84 

			
	AC=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

		
	OS0=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires;
		
	OS1 =	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires; and
		
	SP1 =	  	the average of the Last Reported Sale Prices of Common Stock over the ten consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer
expires.

 The adjustment to the Conversion Rate under the preceding paragraph will occur at the close of
business on the tenth Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within 10 Trading Days immediately following, and including, the
expiration date of any tender or exchange offer, references with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and the
Conversion Date in determining the applicable Conversion Rate. If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any or all or any
portion of such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of
the purchases that had been effected. In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(e). 
 (f) The
term “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock (or other security) have the right to receive any cash, securities or other property or in
which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other
property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
 (g) In accordance with certain
listing standards of the New York Stock Exchange, in the event the Company shall be required to deliver 20% or more of the Common Stock outstanding at the time the Notes are issued as a result of one of the events described in clauses
(b) through (e) of this Section 15.04, the Company shall, at its option, either obtain stockholder approval of such issuances 

  

 85 

 
or deliver cash in lieu of any shares of the Common Stock otherwise deliverable upon conversions in excess of such limitations (based on the opening price of
the Common Stock on the date when such shares of Common Stock would otherwise be required to be distributed). 
 (h) Except as stated herein,
the Company shall not adjust the Conversion Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or such convertible
or exchangeable securities. 
 (i) Notwithstanding this Section 15.04 or any other provision of this Indenture or the Notes, if any
Conversion Rate adjustment becomes effective, or any Ex-Dividend Date for any issuance, dividend or distribution (relating to a required Conversion Rate adjustment) occurs, during the period beginning on, and including, the open of business on a
Conversion Date and ending on, and including, the close of business on the last Trading Day of a related Observation Period, the Board of Directors shall make adjustments to the Conversion Rate and the amount of cash and number of shares of Common
Stock, if any, issuable upon conversion of the Notes, as may be necessary or appropriate to effect the intent of this Section 15.04 and the other provisions of Article 15 and to avoid unjust or inequitable results, as determined in good faith
by the Board of Directors. Any adjustment made pursuant to this Section 15.04(i) shall apply in lieu of the adjustment or other term that would otherwise be applicable. 
 (j) In addition to those required by clauses (a), (b), (c), (d) and (e) of this Section 15.04, and to the extent permitted by applicable
law and subject to the applicable rules of the New York Stock Exchange, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase
would be in the Company’s best interest. In addition, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection
with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the holder of each Note at its last address appearing
on the Note Register provided for in Section 2.06 a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it
will be in effect. 
 (k) Notwithstanding anything else in this Indenture, the applicable Conversion Rate will not be adjusted: 

(i) upon the issuance of any shares of the Common Stock pursuant to any present or future plan providing for the reinvestment of
dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of the Common Stock under any plan; 
  

 86 

 (ii) upon the issuance of any shares of the Common Stock or options or rights to purchase
or acquire those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries; 
 (iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued; 
 (iv) for a change in the par value of the Common Stock; 
 (v) for accrued and unpaid interest
and Additional Interest, if any; or 
 (vi) for any transactions described in this Section 15.04 if Noteholders
participate (as a result of holding the Notes, and at the same time as holders of Common Stock participate) in such transactions as if such Noteholders held a number shares of Common Stock equal to the Conversion Rate at the time such adjustment
would be required, multiplied by a number equal to the principal amount of Notes held by such holder divided by $1,000, without having to convert their Notes. 
 (l) All calculations and other determinations under this Article 15 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share. No adjustment in the Conversion Rate
shall be required unless such adjustment would require an increase or decrease of at least 1% in such Conversion Rate; provided, however, that any adjustments which by reason of this Section 15.04(l) are not required to be made
shall be carried forward and taken into account in any subsequent adjustment. Notwithstanding the foregoing, upon any conversion of Notes by a Noteholder (solely with respect to the Notes to be converted), the Company shall give effect to all
adjustments that it has otherwise deferred pursuant to the immediately preceding sentence, and those adjustments will no longer be carried forward and taken into account in any future adjustment. 
 (m) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent other than the
Trustee an Officers’ Certificate setting forth the Conversion Rate after 

  

 87 

 
such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly
after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such
adjustment of the Conversion Rate to the holder of each Note at its last address appearing on the Note Register provided for in Section 2.06 of this Indenture, within ten days of the effective date of such adjustment. Failure to deliver such
notice shall not affect the legality or validity of any such adjustment. 
 (n) For purposes of this Section 15.04, the number of shares
of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay
any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. 
 Section 15.05. Shares to Be
Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes
are presented for conversion. 
 Section 15.06. Effect of Reclassification, Consolidation, Merger or Sale. In case of
(i) any recapitalization, reclassification or change affecting the Common Stock (other than changes resulting from a subdivision or combination covered by Section 15.04(a)), (ii) a consolidation, merger or combination involving the
Company, (iii) a sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an entirety, or (iv) any statutory share exchange, in each case as a result of which the 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 “Merger Event”), then: 
 (a) the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply
with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) permitted under Section 11.01 providing for the conversion and settlement of the
Notes as set forth in this Indenture. Such supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 15. If, in the case of any Merger Event, the
Reference Property (as defined below) includes shares of stock 

  

 88 

 
or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change,
consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the holders of the Notes as the Board
of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the repurchase rights set forth in Article 16 herein. 
 In the event the Company shall execute a supplemental indenture pursuant to this Section 15.06, the Company shall promptly file with the Trustee an
Officers’ Certificate briefly stating the reasons therefore, the kind or amount of cash, securities or property or asset that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and
that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Noteholders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Noteholder, at its address
appearing on the Note Register provided for in this Indenture, within twenty days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
 (b) Notwithstanding the provisions of Section 15.02(a), and subject to the provisions of Section 15.01 and Section 15.03, at and after the
effective time of such Merger Event, (i) the right to convert each $1,000 principal amount of Notes into cash and shares of Common Stock, if any, as set forth in Section 15.02 will be changed to a right to convert such Note into the kind
and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the applicable Conversion Rate prior to such transaction would have
owned or been entitled to receive (the “Reference Property”) upon such transaction and (ii) the related amounts owing upon conversion shall be settled as set forth under clause (c) below. The Company shall not become a
party to any Merger Event unless its terms are consistent with this Section 15.06. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash and shares of Common Stock as set forth in
Section 15.01 and Section 15.02 prior to the effective date of such Merger Event. For purposes of the foregoing, if the Merger Event causes 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), the Reference Property into which the notes will be convertible 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 “Weighted Average Consideration”). In such case, the Company shall notify the holders of the composition of the Weighted Average Consideration as soon as practicable after the
composition of the Weighted Average Consideration is determined. 
  

 89 

 (c) With respect to each $1,000 principal amount of Notes surrendered for conversion after the effective
date of any such Merger Event, the Company’s obligation to deliver amounts owing upon conversion shall be settled in cash and units of Reference Property, if any, in accordance with Section 15.02(b) as follows: 
 (i) the Company shall deliver in respect of each $1,000 principal amount of Notes being converted, an amount equal to the sum of the Daily
Settlement Amounts for each of the forty consecutive Trading Days during the Observation Period for such Note, such Daily Settlement Amounts determined as if the reference to “the Daily VWAP of the Common Stock” in the definition of Daily
Conversion Value and Daily Settlement Amount were instead a reference to “the Daily VWAP of a unit of Reference Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any
combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive.” 
 (ii) The Company will deliver the cash in lieu of fractional units of Reference Property as set forth pursuant to Section 15.02(l) (provided that the amount of such cash shall be determined as if
references in such Section to “Daily VWAP” were instead a reference to “the Daily VWAP of a unit of Reference Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any
combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration”). (iii) The Daily Settlement Amounts (if
applicable) and Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. 
 (d) The above provisions of this Section shall similarly apply to successive Merger Events. 
 Section 15.07. Certain Covenants. (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges
with respect to the issue thereof. 
 (b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of
conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules
and interpretations of the Commission, 

  

 90 

 
secure such registration or approval, as the case may be. For the avoidance of doubt, if a conversion of Notes is effected pursuant to an exemption from the
registration requirements of the Securities Act contained in Section 3(a)(9) thereof (or a successor provision), then the Company will not be required to register the shares of Common Stock issued upon conversion under the Securities Act.

 (c) The Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated
quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes. 
 Section 15.08. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or
responsibility to any Noteholder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion
Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities
or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither
the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 15.06 relating either to the kind or amount of shares
of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.06 or to any adjustment to be made with respect thereto, but, subject to the
provisions of Section 8.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officers’ Certificate and Opinion of
Counsel (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any
event contemplated by Section 15.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in
Section 15.01(b) with respect to the commencement or termination 

  

 91 

 
of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the
Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 15.01(b). 
 Section 15.09. Notice to 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 15.04; or 
 (b) the Company shall authorize the granting to all of the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any share of any class or any other rights, options or warrants; or

 (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock,
or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale
or transfer of all or substantially all of the assets of the Company; or 
 (d) of the voluntary or involuntary dissolution, liquidation or
winding-up of the Company; 
 the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at its address appearing on the Note
Register, provided for in Section 2.06 of this Indenture, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or
(ii) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. 
 Section 15.10. Stockholder Rights Plans. To the extent that the Company has a stockholder rights plan or other “poison pill” in
effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall 

  

 92 

 
be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear
such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan or poison pill, as the same may be amended from time to time. If prior to the time of conversion, however, the rights have separated from the
shares of Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that the holders of the Notes would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon conversion of the
Notes, the Conversion Rate will be adjusted at the time of separation as if the Company has distributed to all holders of Common Stock, shares of Capital Stock of the Company, evidence of indebtedness, assets, property, rights or warrants as
provided in Section 15.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 
 ARTICLE 16 
 REPURCHASE OF NOTES AT OPTION
OF HOLDERS 
 Section 16.01. [Reserved.].  
 Section 16.02. Repurchase at Option of Holders upon a Fundamental Change. (a) If there shall occur a Fundamental Change at any time
prior to the Maturity Date, then each Noteholder shall have the right, at such Noteholder’s option, to require the Company to repurchase for cash all of such holder’s Notes, or any portion thereof that is an integral multiple of $1,000
principal amount, on the date (the “Fundamental Change Purchase Date”) specified by the Company that is not less than 20 or more than 35 calendar days after the date of the Fundamental Change Company Notice (as defined below) at a
repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, including unpaid Additional Interest, if any, thereon to, but excluding, the Fundamental Change Purchase Date, which the Company may extend to
comply with applicable law (the “Fundamental Change Purchase Price”), unless the Fundamental Change Purchase Date is after an Interest Record Date and on or prior to the related Interest Payment Date, in which case interest accrued
but unpaid to the Interest Payment Date will be paid to Noteholders as of the preceding Interest Record Date and the Fundamental Change Purchase Price payable to the Noteholder surrendering the Note for repurchase pursuant to this Article 16 shall
be equal to the principal amount of Notes subject to repurchase. Repurchases of Notes under this Section 16.02 shall be made, at the option of the Noteholder thereof, upon: 
 (i) delivery to the Paying Agent by a holder of a duly completed notice (the “Fundamental Change Purchase Notice”) in the
form set forth on the reverse of the Note on or prior to the Business Day immediately preceding the Fundamental Change Purchase Date; and 
  

 93 

 (ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time after
delivery of the Fundamental Change Purchase Notice (together with all necessary endorsements) at the Corporate Trust office of the Paying Agent, such delivery being a condition to receipt by the holder of the Fundamental Change Purchase Price
therefor; provided that such Fundamental Change Purchase Price shall be so paid pursuant to this Section 16.02 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related
Fundamental Change Purchase Notice. 
 The Fundamental Change Purchase Notice shall state: 
 (A) if certificated, the certificate numbers of the Notes to be delivered for repurchase or if the Notes are not in certificated form, the
Fundamental Change Purchase Notice must comply with appropriate Depositary procedures; 
 (B) the portion of the principal
amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and 
 (C) that the Notes are to be
repurchased by the Company pursuant to the applicable provisions of the Notes and the Indenture. 
 Any repurchase by the Company
contemplated pursuant to the provisions of this Section 16.02 shall be consummated by the payment of the Fundamental Change Purchase Price on the later of the Fundamental Change Purchase Date and the time of the book-entry transfer or delivery
of the Note as described in Section 16.04(a). 
 Notwithstanding anything herein to the contrary, any holder delivering to the Paying
Agent the Fundamental Change Purchase Notice contemplated by this Section 16.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of business on the Business Day
immediately preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 16.03 below. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof. 
  

 94 

 (b) On or before the twentieth day after the occurrence of the effective date of a Fundamental Change,
the Company shall mail or cause to be mailed to all holders of record of the Notes a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at
the option of the Noteholders arising as a result thereof. Such mailing shall be by first class mail. The Company shall also deliver a copy of the Fundamental Change Company Notice to the Trustee, the Paying Agent and the Conversion Agent on or
before the twentieth day after the occurrence of the effective date of the Fundamental Change. Simultaneously with the providing of such notice, the Company will also publish a notice containing the information set forth in the Fundamental Change
Company Notice on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change; 
 (ii) the effective date of the Fundamental Change; 
 (iii) the last date on which a holder may exercise the repurchase right pursuant to this Article 16; 
 (iv) the Fundamental Change Purchase Price; 
 (v) the Fundamental Change Purchase Date; 
 (vi) the name and address of the Paying Agent and
the Conversion Agent, if applicable; 
 (vii) if applicable, the applicable Conversion Rate and any adjustments to the
applicable Conversion Rate; 
 (viii) if applicable, that the Notes with respect to which a Fundamental Change Purchase Notice
has been delivered by a holder may be converted only if the holder withdraws the Fundamental Change Purchase Notice in accordance with the terms of this Indenture; 
 (ix) that the holder must exercise the repurchase right on or prior to the close of business on the Business Day immediately preceding the
Fundamental Change Purchase Date (the “Fundamental Change Expiration Time”); 
 (x) that the holder shall
have the right to withdraw any Notes surrendered prior to the Fundamental Change Expiration Time; and 
 (xi) the procedures
that holders must follow to require the Company to repurchase their Notes. 
  

 95 

 No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 16.02. 
 (c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the holders upon a Fundamental Change if there has occurred and is continuing an Event of Default (except in the case of an Event of Default that
is cured by the payment of the Fundamental Change Purchase Price with respect to such Notes). 
 (d) In connection with any purchase offer,
the Company will: 
 (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the
Exchange Act, if required under the Exchange Act, 
 (ii) file a Schedule TO or any successor or similar schedule, if required
under the Exchange Act, and 
 (iii) otherwise comply with all federal and state securities laws in connection with any offer
by the Company to purchase the Notes. 
 Section 16.03. Withdrawal of Fundamental Change Purchase Notice. (a) A Fundamental
Change Purchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Corporate Trust office of the Paying Agent in accordance with this Section 16.03 at any time prior to the close of business on the Business Day
immediately preceding the Fundamental Change Purchase Date, specifying: 
 (i) the principal amount of the Note with respect
to which such notice of withdrawal is being submitted, and 
 (ii) if certificated, the certificate number, if any, of the
Note in respect of which such notice of withdrawal is being submitted or if the Notes are not in certificated form, the notice must comply with appropriate procedures of the Depositary, and 
 (iii) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Purchase Notice, which portion
must be in principal amounts of $1,000 or an integral multiple of $1,000. 
 Section 16.04. Deposit of Fundamental Change Purchase
Price. (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 5.04) on or prior
to 11:00 a.m., 

  

 96 

 
New York City time, on the Fundamental Change Purchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate
Fundamental Change Purchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the Fundamental Change Expiration
Time) will be made on the later of (i) the Fundamental Change Purchase Date with respect to such Note (provided the holder has satisfied the conditions in Section 16.02) and (ii) the time of book-entry transfer or the delivery
of such Note to the Trustee (or other Paying Agent appointed by the Company) by the holder thereof in the manner required by Section 16.02 by mailing checks for the amount payable to the holders of such Notes entitled thereto as they shall
appear in the Note Register, provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such
payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Purchase Price. 
 (b) If
by 11:00 a.m. New York City time, on the Fundamental Change Purchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased as a
result of the corresponding Fundamental Change, then (i) such Notes will cease to be outstanding, (ii) interest, including Additional Interest, if any, will cease to accrue on such Notes, and (iii) all other rights of the holders of
such Notes will terminate (other than the right to receive the Fundamental Change Purchase Price and previously accrued but unpaid interest, including Additional Interest, if any, upon delivery of the Notes), whether or not book-entry transfer of
the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent. 
 (c) Upon surrender of a Note that is to be
repurchased in part pursuant to Section 16.02, the Company shall execute and the Trustee shall upon receipt of a Company Order authenticate and deliver to the holder a new Note in an authorized denomination equal in principal amount to the
unrepurchased portion of the Note surrendered.

period from and after such date. 
 Section 17.07. No Security Interest Created. Nothing in this Indenture or in the Notes,

 Section 17.08. Trust Indenture Act. This Indenture is hereby made subject to, and shall be governed by, the provisions of the Trust Indenture
Act required to be part of and to govern indentures qualified under the Trust Indenture Act upon such qualification regardless of whether this Indenture shall ever be so

qualified; provided that this Section 17.08 shall not constitute any admission or acknowledgment by any party hereto that any such qualification
is required prior to the time such qualification is in fact required under the terms of the Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof that is required to be included in an indenture
qualified under the Trust Indenture Act, such required provision shall control. 
 Section 17.09. Benefits of Indenture. Nothing
in this Indenture or in the Notes, expressed or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Conversion Agent, any authenticating agent, any Note Registrar and their successors hereunder or the Noteholders,
any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 Section 17.10. Table of Contents, Headings,
Etc. The table of contents and the titles and headings of the articles and sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the

 Section 17.11. Authenticating Agent. The Trustee may appoint an authenticating agent that shall be
authorized to act on its behalf and subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Section 2.05,
Section 2.06, Section 2.07, Section 2.08, Section 11.04 and Section 16.04 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to
authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of
authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a
Person eligible to serve as trustee hereunder pursuant to Section 8.09. 
 Any corporation or other entity into which any authenticating
agent may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity
succeeding to all or substantially all of the corporate trust business of any authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this Section,
without the execution or filing of any paper or any further act on the part of the parties hereto or the authenticating agent or such successor corporation or other entity. 
  

 100 

 Any authenticating agent may at any time resign by giving written notice of resignation to the Trustee
and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice of such appointment to the
Company and shall mail notice of such appointment to all Noteholders as the names and addresses of such holders appear on the Note Register. 
 The Company agrees to pay to the authenticating agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable.

 The provisions of Section 8.02, Section 8.03, Section 8.04, Section 9.03 and this Section 17.11 shall be
applicable to any authenticating agent. 
 If an authenticating agent is appointed pursuant to this Section, the Notes may have endorsed
thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
                                       
                                      , as
Authenticating Agent, certifies that this is one of the Notes described in the within-named Indenture.

 Section 17.12. Execution in Counterparts. This Indenture may be executed in any number
of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 
 Section 17.13. Severability. In the event any provision of this Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the
remaining provisions shall not in any way be affected or impaired. 
 Section 17.14. Waiver of Jury Trial. EACH OF THE COMPANY
AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

  

 101 

 Section 17.15. Force Majeure. In no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or
military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable
efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

 KINETIC CONCEPTS, INC. 
 % Convertible Senior Note due 20     
 This Note is one of a duly authorized
issue of Notes of the Company, designated as its         % Convertible Senior Notes due 20     (herein called the “Notes”), initially limited to the aggregate
principal amount of $             (or $             if the Initial Purchasers exercise their option to
purchase additional Notes in full as set forth in the Purchase Agreement) all issued or to be issued under and pursuant to an Indenture dated as of April 21, 2008 (herein called the “Indenture”), between the Company, KCI USA,
Inc. 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. This Note is guaranteed, on a
subordinated basis, as set forth in the Indenture. 
 In case an Event of Default, other than an Event of Default with respect to the Company
specified in Section 7.01(h) or 7.01(i) of the Indenture, shall have occurred and be continuing, the principal of and interest, including Additional Interest, if any, on all Notes may be declared, by either the Trustee or Noteholders of not
less than 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.
Notwithstanding the previous sentence, in case an Event of Default with respect to the Company specified in Section 7.01(h) or 7.01(i) of the Indenture shall have occurred and be continuing, the principal and interest, including Additional
Interest, if any, on all Notes shall become immediately due and payable without any declaration by the Noteholders or the Trustee. 
 Subject
to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Purchase Price and the principal amount on the Maturity Date, as the case may be, to the holder who surrenders a
Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 
 The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the holders of the Notes, and
in other circumstances, with the consent of the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of
the Indenture and the Notes as described therein. It is also 

  

 A-6 

 
provided in the Indenture that, subject to certain exceptions, the holders of a majority in aggregate principal amount of the Notes at the time outstanding
may on behalf of the holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
 No
reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and accrued and unpaid interest, and Additional
Interest, if any, on this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed. 
 The Notes are
issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided
in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover
any tax, assessments or other governmental charges that may be imposed in connection therewith as a result of the name of the Noteholder of the new Notes issued upon such exchange of Notes being different from the name of the Noteholder of the old
Notes surrendered for such exchange. 
 The Notes are not subject to redemption through the operation of any sinking fund or otherwise.

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