 ARTICLE 2 

THE SECURITIES 

Section 2.01. Form and Dating. (a) The Securities and the Trustee’s certificate of authentication shall be
substantially in the respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. The
Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication. The terms and provisions contained in the Securities shall constitute, and are hereby expressly
made, a part of this Indenture, and 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. However, to the extent any provision of any Security conflicts
with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.  
 (b) All
of the Securities shall be issued initially in the form of one or more Global Securities, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for
the depositary, The Depository Trust Company (“DTC”) (such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co.,
duly executed by the Company and authenticated by the Trustee as hereinafter provided.  
 Each Global Security shall represent such
of the outstanding Securities as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities
represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, purchases or conversions of such Securities. Any adjustment of the aggregate principal amount of a Global Security to reflect the amount of any
increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 and shall be made on the records of the
Trustee and the Depositary. 
 Members of, or participants in, the Depositary (“Agent Members”) shall have no rights
under this Indenture with respect to any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of
the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the Trustee or any agent of the Company or the Trustee
from giving effect to any written certification, proxy or other authorization furnished by the Depositary or (2) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights
of a Holder of any Security.  

  
 -11- 








 (c) The Company shall execute and the Trustee shall, in accordance with this
Section 2.01(c), authenticate and deliver initially one or more Global Securities that (1) shall be registered in the name of the Depositary, (2) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s
instructions and (3) shall bear a legend substantially to the following effect: 
 “UNLESS THIS CERTIFICATE IS PRESENTED BY AN
AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER,
PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER
REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN
THE INDENTURE AND UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO
THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.” 

Section 2.02. Execution and Authentication; Payments of Interest and Defaulted Amounts. (a) The Securities shall be
issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral multiple thereof. An Officer shall sign the Securities for the Company by manual or facsimile signature attested by the manual or
facsimile signature of the Secretary or an Assistant Secretary of the Company. Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Security which has been authenticated
and delivered by the Trustee. If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless. A Security shall not be valid until an authorized
signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.  

  
 -12- 








 (b) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may
appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 

(c) The Trustee shall authenticate and make available for delivery Securities for original issue in the aggregate principal amount of
up to $300,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Securities purchased by the Initial Purchasers pursuant to the exercise of their option to purchase additional Securities as set forth in the
Purchase Agreement) upon receipt of a written order or orders of the Company signed by two Officers, at least one of whom shall be the principal executive officer, principal financial officer or principal accounting officer of the Company (a
“Company Order”). The Company Order shall specify the amount of Securities to be authenticated, shall provide that all such Securities will be represented by a Global Security and the date on which each original issue of Securities
is to be authenticated. The Company at any time or from time to time may, without the consent of the Holders, reopen this Indenture and issue additional Securities under this Indenture having the same ranking, interest rate, maturity and other terms
as the Securities initially issued hereunder (other than differences in the issue price and interest accrued prior to the issue date of such additional Securities) in an unlimited aggregate principal amount, and entitled to all of the benefits of
this Indenture; provided that if any such additional Securities are not fungible with the Securities initially issued hereunder for U.S. federal income tax purposes, such additional Securities shall have a separate CUSIP number.
Such additional Securities shall, together with the Securities initially issued hereunder, constitute a single series of Securities under this Indenture, including without limitation in determining the necessary Holders who may take the actions or
consent to the taking of actions as specified in this Indenture. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such additional Securities, the Trustee shall receive, and, shall
be fully protected in relying upon: (a) an Officers’ Certificate delivered in accordance with Section 2.01 and Section 11.04 and (b) an Opinion of Counsel which shall state (1) that the form and terms of such Securities
have been established by or pursuant to a resolution of the Board of Directors in accordance with Section 2.01 and Section 2.02 and in conformity with the provisions of this Indenture, (2) that such Securities, when authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms,
subject to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles, and (3) that all conditions precedent under this
Indenture in respect of the execution and delivery by the Company of such Securities have been complied with. 
 (d) Accrued interest
on the Securities shall be computed on the basis of a 360-day year composed of twelve 30-day months. The Person in whose name any Security (or its predecessor) is registered on register of the Primary Registrar at the close of business on any
Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the office or agency of the Company maintained by the Company for such
purposes in the contiguous United States, which shall 

  
 -13- 








 
initially be the Corporate Trust Office. The Company shall pay interest (i) on any Certificated Securities by wire transfer in immediately available funds to that Holder’s account
within the United States or (ii) on any Global Security by wire transfer of immediately available funds to the account of the Depositary or its nominee. 

(e) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date by virtue of its having been
such Holder but shall accrue interest per annum at the rate borne by the Securities plus one percent, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date to, but excluding, the date on
which such Defaulted Amounts shall have been paid by the Company, at its election in each case, as provided in subsection (i) or (ii) below: 

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Securities (or their
respective predecessor Securities) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of the Defaulted Amounts proposed to be paid on each Security 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 Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to
the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of
such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 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 the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be delivered to each
Holder, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose
names the Securities (or their respective predecessor Securities) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following subsection (ii) of this Section 2.02(e). 

(ii) The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of
any securities exchange or automated quotation system on which the Securities 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 2.03. Registrar, Paying Agent and Conversion Agent. The Company shall maintain one or more offices or agencies
where Securities may be presented for registration of  

  
 -14- 








 
transfer or for exchange (each, a “Registrar”), one or more offices or agencies where Securities may be presented for payment (each, a “Paying Agent”), one
or more offices or agencies where Securities may be presented for conversion (each, a “Conversion Agent”) and one or more offices or agencies where notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served, such offices and agencies to be maintained in the contiguous United States. The Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and an office or agency where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, The City of New York. One of the Registrars (the “Primary Registrar”) shall keep a register of the Securities and of their
registration of transfer and exchange. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency.  

The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall give prompt written notice to the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent,
Conversion Agent or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent (except
for the purposes of Section 5.01 and Article 9). 
 The Company hereby initially designates the Trustee as Paying Agent, Primary
Registrar, Securities Custodian and Conversion Agent and each of the Corporate Trust Office of the Trustee and the office or agency of the Trustee in the Borough of Manhattan, The City of New York, as an office or agency of the Company for each of
the aforesaid purposes. 
 Section 2.04. Paying Agent to Hold Money in Trust. Prior to 11:00 a.m., New York City time, on
each due date of the principal of or interest on any Securities, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal or interest so becoming due. A Paying Agent shall hold in trust for the benefit of the Holders or
the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities, and shall notify the Trustee of any default by the Company (or any other obligor on the Securities) in making any such payment. If the
Company or an Affiliate of the Company acts as Paying Agent, it shall, before 11:00 a.m., New York City time, on each due date of the principal of or interest on any Securities, segregate the money and hold it as a separate trust fund for the
benefit of the Holders. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any default, upon written request to a Paying Agent, require such Paying
Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money. 

Section 2.05. Holder. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of the Holders. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee at least seven Business Days before each semiannual interest payment date, and at such other times as the Trustee
may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders. 

  
 -15- 








 Section 2.06. Transfer and Exchange; Transfer Restrictions. (a) Subject
to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of
Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall
be duly endorsed or accompanied by an assignment form in form satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any
Security for registration of transfer or exchange at an office or agency maintained pursuant to Section 2.03, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s
request. Any exchange or registration of transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto, and
provided, that this sentence shall not apply to any exchange pursuant to Section 2.07, Section 2.10, Section 3.06, Section 4.02(d) or Section 10.05.  

Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of any Securities or portions thereof
in respect of which a Repurchase Exercise Notice pursuant to Section 3.02(c) has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased). 

All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt and
entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 
 (b) Any Registrar
appointed pursuant to Section 2.03 shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 

(c) Each Holder agrees to indemnify the Company, each Registrar and the Trustee against any liability that may result from the registration of
transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable United States federal or state securities law. 

(d) Every Security 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 Securities that is 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 this 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. 

  
 -16- 








 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 Securities, or such shorter 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 law, any certificate evidencing such Security (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 Securities 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 sold 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: 
 (1) 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 

(2) AGREES FOR THE BENEFIT OF AEGERION PHARMACEUTICALS, 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 THERETO 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. 

  
 -17- 








 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. 

No transfer of any Security prior to the Resale Restriction Termination Date will be registered by the Security Registrar unless the
applicable box on the Form of Assignment and Transfer has been checked. 
 Any Security (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 Security for exchange to the Security Registrar in accordance with the provisions of this Section 2.06, be
exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.06(d) and shall not be assigned a restricted CUSIP number. The Company shall be
entitled to instruct the Custodian in writing to so surrender any Global Security as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, the Custodian shall so surrender
such Global Security for exchange; and any new Global Security so exchanged therefor shall not bear the restrictive legend specified in this Section 2.06(d) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify
the Trustee upon the occurrence of the Resale Restriction Termination Date and promptly after a registration statement, if any, with respect to the Securities or any Common Stock issued upon conversion of the Securities has been declared effective
under the Securities Act. 
 (e) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon
conversion of such Security shall bear a legend in substantially the following form (unless the Security 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 or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon
conversion of Securities 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 or any similar provision then in force 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: 

(1) 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 

  
 -18- 








 (2) AGREES FOR THE BENEFIT OF AEGERION PHARMACEUTICALS, 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 OF THE SERIES OF NOTES
UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO 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 TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK 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. 

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). 
 Any Security or Common Stock issued upon the
conversion or exchange of a Security that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months preceding) may not be resold by


  
 -19- 








 
such Affiliate (or such Person, as the case may be) 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 Security or Common Stock, as the case may be, no longer being a “restricted security” (as defined under Rule 144 under the Securities Act). The Company shall cause any Security that is repurchased or owned
by it to be surrendered to the Trustee for cancellation in accordance with Section 2.11. 
 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 Security (including any transfers between or among
Agent Members or other beneficial owners of interests in any Global Security) 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. 

Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary. 

Section 2.07. Replacement Securities. If any mutilated Security is surrendered to the Company, a Registrar or the Trustee,
or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save
each of them harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute, and upon its written request the Trustee shall authenticate
and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be repurchased
by the Company pursuant to Article 3, the Company in its discretion may, instead of issuing a new Security, pay or repurchase such Security, as the case may be. 

Upon the issuance of any new Securities under this Section 2.07, the Company may require the payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 

Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder. 

  
 -20- 








 The provisions of this Section 2.07 are (to the extent lawful) exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 

Section 2.08. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee,
except for those canceled by it, those converted pursuant to Article 4, those delivered to it for cancellation or surrendered for transfer or exchange and those described in this Section 2.08 as not outstanding.  

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that
the replaced Security is held by a protected purchaser. 
 If a Paying Agent (other than the Company or an Affiliate of the Company) holds
on the Maturity Date money sufficient to pay the principal of and accrued interest on Securities (or portions thereof) payable on that date, then on and after such Maturity Date such Securities (or portions thereof, as the case may be) shall cease
to be outstanding and interest on them shall cease to accrue. 
 Subject to the restrictions contained in Section 2.09, a Security does
not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 
 Section 2.09. Treasury
Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any notice, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate
of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities that a Responsible Officer of
the Trustee actually knows are so owned shall be so disregarded. Securities so owned that have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with
respect to the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor.  

Section 2.10. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and
execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of Certificated Securities but may have variations that the Company considers
appropriate for temporary Securities and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of a Company Order, shall authenticate and deliver definitive Securities
in exchange for temporary Securities. Holders of temporary Securities shall be entitled to all the benefits of this Indenture.  

Section 2.11. Cancellation; Repurchase. The Company shall cause all Securities surrendered for the purpose of payment,
repurchase, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s Agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation. The
Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any  

  
 -21- 








 
Securities surrendered to them for registration of transfer, exchange, redemption, payment or conversion. The Company shall instruct the Trustee in writing to cancel all Securities surrendered
for the purpose of payment, repurchase, registration of transfer, exchange, conversion or cancellation, and the Trustee and no one else shall promptly cancel, in accordance with its standard procedures and upon the Company’s written
instruction, all Securities so surrendered and shall dispose of canceled Securities (subject to the record retention requirements of the Exchange Act), in accordance with its standard procedures, and no Securities shall be authenticated in exchange
thereof except as expressly permitted by any of the provisions of this Indenture. The Company may not hold or resell such Securities or issue new Securities to replace Securities that it has purchased or otherwise acquired or that have been
delivered to the Trustee for cancellation. 
 The Company may, to the extent permitted by law, and directly or indirectly (regardless of
whether such Securities are surrendered to the Company), repurchase Securities in the open market, by tender offer or exchange offer, by private agreement through counterparties or otherwise, whether by the Company or its Subsidiaries, including by
cash-settled swaps or other derivatives and, in each case, at any price. The Company shall cause any Securities so purchased (other than Securities repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for
cancellation in accordance with this Section 2.11, and they shall no longer be considered outstanding under this Indenture upon their repurchase. Any Securities held by the Company or one of its Subsidiaries shall be disregarded for voting
purposes in connection with any notice, waiver, consent or direction requiring the vote or concurrence of Holders. 

Section 2.12. Additional Transfer and Exchange Requirements. (a) A Global Security may not be transferred, in whole or
in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any transfer of a Security that is issued
in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person.
Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance with this Section 2.12.  

(b) The provisions of subsections (i), (ii), (iii) and (iv) below shall apply only to Global Securities: 

(i) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged
in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Security may be exchanged for Certificated Securities registered in the names of any
Person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or the Depositary has ceased to be a “clearing agency”
registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days or (B) an Event of Default has occurred and is continuing and a beneficial owner requests that its Securities be exchanged for
Certificated Securities. Any Global Security  

  
 -22- 








 
exchanged pursuant to clause (A) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (B) above may be exchanged in whole or
from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the name of a
Person other than the Depositary or a nominee thereof shall not be a Global Security.  
 (ii) Securities
issued in exchange for a Global Security or any portion thereof shall be issued in fully-registered book-entry form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so
exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any applicable legend provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the
Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as Securities Custodian for the Depositary or its
nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such
surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof; provided, however, that any Global Security
surrendered for exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.06(a).  

(iii) Subject to the provisions of subsection (v) below, the registered Holder may grant proxies and otherwise authorize
any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities. 

(iv) In the event of the occurrence of any of the events specified in subsection (i) above, the Company will promptly make
available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 

(v) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this
Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an
Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Security. 

  
 -23- 








 (c) In the event that Certificated Securities are issued in exchange for beneficial interests in
Global Securities and, thereafter, the events or conditions specified in Section 2.12(b)(i) that required such exchange shall cease to exist, the Company shall deliver notice to the Trustee and to the Holders stating that Holders may exchange
Certificated Securities for interests in Global Securities by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such notice be given. Thereafter, if
Certificated Securities are presented by a Holder to a Registrar with a request: 
 (i) to register the transfer of such
Certificated Securities to a Person who will take delivery thereof in the form of a beneficial interest in a Global Security; or 

(ii) to exchange such Certificated Securities for an equal principal amount of beneficial interests in a Global Security, which
beneficial interests will be owned by the Holder transferring such Certificated Securities, 
 the Registrar shall register the transfer or make the
exchange as requested by canceling such Certificated Securities and causing, or directing the Securities Custodian to cause, the aggregate principal amount of the applicable Global Security to be increased accordingly and, if no such Global Security
is then outstanding, the Company shall issue and the Trustee, upon receipt of a Company Order, shall authenticate and deliver a new Global Security; provided, however, that the Certificated Securities presented or surrendered for
registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.06(a).  

Section 2.13. CUSIP Numbers. The Company in issuing the Securities may use one or more “CUSIP” numbers (if then
generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such notice or related action by the Company contemplated thereby shall not be
affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.  

ARTICLE 3 
 NO
REDEMPTION; REPURCHASE UPON A FUNDAMENTAL CHANGE 

Section 3.01. No Optional Redemption. The Company shall not have the option to redeem the Securities prior to the Maturity
Date. No sinking fund is provided for the Securities. 
 Section 3.02. Repurchase At Option of The Holder Upon A
Fundamental Change. (a) Subject to the satisfaction of the requirements of this Article 3, if a Fundamental Change occurs at any time prior to the Maturity Date, each Holder shall have the right, at its option, to require the Company to
repurchase for cash all of their Securities, or any portion of the principal thereof that is equal to $1,000 or an integral multiple of $1,000 at a repurchase price (the “Fundamental Change Repurchase Price”) equal to
100% of the principal amount of the Securities to be 

  
 -24- 








 
repurchased plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date (unless such Fundamental Change Repurchase Date falls after a Regular Record Date
and on or prior to the corresponding Interest Payment Date, in which case the Company shall pay the full amount of accrued and unpaid interest payable on such Interest Payment Date to the Holder of record at the close of business on such Regular
Record Date and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of the Securities to be repurchased). The Company shall provide to the Holders of the Securities, the Trustee, the Paying Agent and the Conversion
Agent (if other than the Trustee) a notice (i) at least 35 Scheduled Trading Days prior to the anticipated effective date of a Fundamental Change or (ii) if the Company does not have knowledge of a Fundamental Change at least 35 Scheduled
Trading Days prior to the anticipated effective date of such transaction, within two Business Days of the earlier of (x) the date upon which the Company receives, or otherwise becomes aware, of the anticipated effective date of such Fundamental
Change and (y) the actual effective date of such Fundamental Change. 
 (b) In addition to the notice required pursuant to
Section 3.02(a), on or before the 15th Business Day after the date on which a Fundamental Change becomes effective, the Company shall provide to all Holders of the Securities, the Trustee and the Conversion Agent (if other than the Trustee) a
notice of the occurrence of the Fundamental Change and of the resulting repurchase right (the “Fundamental Change Repurchase Right Notice”). The Fundamental Change Repurchase Right Notice shall state:  

(i) the event or events giving rise to the Fundamental Change; 

(ii) if the Fundamental Change also constitutes a Make-Whole Fundamental Change; 

(iii) the Conversion Rate and any adjustments to the Conversion Rate; 

(iv) the effective date of the Fundamental Change; 

(v) the last date on which a Holder may exercise the repurchase right; 

(vi) the Fundamental Change Repurchase Price; 

(vii) the Fundamental Change Repurchase Date; 

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

(ix) that the Securities with respect to which a Repurchase Exercise Notice has been given by the Holder may be converted only
if the Holder withdraws the Repurchase Exercise Notice as described in Section 3.02(d); and 
 (x) the procedures that
Holders must follow to require the Company to repurchase their Securities. 

  
 -25- 








 Simultaneously with providing the Fundamental Change Repurchase Right Notice, the Company shall
issue a press release and publish the information through a public medium customary for such press releases. 
 (c) To exercise the
repurchase right in connection with a Fundamental Change, a Holder must deliver, prior to the close of business, on the second Business Day immediately preceding the Fundamental Change Repurchase Date, the Securities to be purchased to the Paying
Agent, duly endorsed for transfer, or effect book-entry transfer of the Securities to the Paying Agent, together with a written notice exercising its right to require the Company to repurchase its Securities or a portion thereof (a
“Repurchase Exercise Notice”), substantially in the form included in Exhibit A hereto, duly completed, to the Paying Agent. The Repurchase Exercise Notice must state:  

(i) if the Securities are Certificated Securities, the certificate numbers of the Securities to be delivered for repurchase;

 (ii) the portion of the principal amount of the Securities to be repurchased, which must be equal to $1,000 or an integral
multiple thereof; and 
 (iii) that the Securities are to be repurchased by the Company as of the Fundamental Change
Repurchase Date pursuant to the applicable provisions of the Securities and this Indenture. 
 If the Securities are Global Securities, the Repurchase
Exercise Notice must comply with the Applicable Procedures. 
 A Holder may withdraw any Repurchase Exercise Notice (in whole or in part) by
a written notice of withdrawal delivered to the Paying Agent prior to the close of business on the second Business Day prior to the Fundamental Change Repurchase Date. The notice of withdrawal must state: 

(i) the principal amount of the Securities for which the Repurchase Exercise Notice has been withdrawn; 

(ii) if Certificated Securities have been issued, the certificate numbers of the withdrawn Securities; and 

(iii) the principal amount, if any, that remains subject to the Repurchase Exercise Notice. 

If the Securities are Global Securities, the withdrawal notice must comply with the Applicable Procedures. 

(d) The Company must repurchase on a date (the “Fundamental Change Repurchase Date”) chosen by the Company that is no
less than 20 and no more than 35 Business Days after the date of the Fundamental Change Repurchase Right Notice with respect to the occurrence of the relevant Fundamental Change, subject to extension to comply with applicable law. To receive payment
of the Fundamental Change Repurchase Price, a Holder must either effect book-entry 

  
 -26- 








 
transfer or deliver the Securities, together with necessary endorsements, to the office of the Paying Agent after delivery of the Repurchase Exercise Notice. Holders shall receive payment of
the Fundamental Change Repurchase Price on the later of (i) the Fundamental Change Repurchase Date and (ii) the time of book-entry transfer or the delivery of the Securities. If the Paying Agent holds money deposited by the Company
sufficient to pay the Fundamental Change Repurchase Price of the Securities on the Fundamental Change Repurchase Date, then with respect to the Securities that have been properly surrendered for repurchase and have not been validly withdrawn:

 (i) the Securities will cease to be outstanding and interest, if any, will cease to accrue (whether or not book-entry
transfer of the Securities is made or whether or not the Securities are delivered to the Paying Agent); and 
 (ii) all other
rights of the Holder of such Securities will terminate (other than the right to receive the Fundamental Change Repurchase Price upon delivery or transfer of the Securities). 

Section 3.03. Compliance With Securities Laws Upon Purchase of Securities. (a) In connection with any offer to
purchase the Securities under Section 3.02, the Company shall comply with all tender offer rules applicable to the Company under the Exchange Act. The Company shall (a) comply with the provisions of Rule 13e-4, Rule 14e-l (or any successor
to either such Rule) and any other tender offer rules, if applicable, under the Exchange Act, (b) file a Schedule TO (or any successor or similar schedule, form or report), if required, under the Exchange Act and (c) otherwise comply with
all federal and state securities laws in connection with such offer by the Company to purchase the Securities upon a Fundamental Change, so as to permit the rights of the Holders and obligations of the Company under Section 3.02 to be exercised
in the time and in the manner specified therein. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 3.03, the Company, shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this Section 3.03 by virtue of such conflict. 

Section 3.04. No Repurchase Upon Acceleration. No Securities may be repurchased on any date at the option of Holders upon a
Fundamental Change if the principal amount of the Securities has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment
of the Fundamental Change Repurchase Price with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Certificated Securities held by it following the acceleration of the Securities (except in the
case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Securities), and any instructions for book-entry transfer of the Securities in compliance with the
procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.  

Section 3.05. Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant
to Section 3.02 exceeds the aggregate Fundamental Change Repurchase Price of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Fundamental Change Repurchase Date, the Trustee or a Paying
Agent, as the case may be, shall return any such excess cash to the Company.  

  
 -27- 








 Section 3.06. Partial Repurchase. Upon surrender of a Security that is to be
repurchased in part pursuant to Section 3.02, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security in an authorized denomination equal in principal amount to the unrepurchased portion of the
Security surrendered. 
 ARTICLE 4 

CONVERSION 

Section 4.01. Conversion Rights. (a) Subject to and upon compliance with the provisions of this Article
4, each Holder of a Security 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 Security (i) subject to
satisfaction of one or more of the conditions described in subsections (b) through (f) of this Section 4.01, at any time prior to the close of business on the Business Day immediately preceding February 15, 2019 under the
circumstances and during the periods set forth in subsections (b) through (f) of this Section 4.01, and (ii) irrespective of the conditions set forth in subsections (b) through (f) of this Section 4.01, on or after
February 15, 2019 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case at an initial conversion rate of 24.2866 shares of Common Stock (subject to adjustment as provided in
Section 4.05, the “Conversion Rate”) per $1,000 principal amount of Securities (subject to the settlement provisions of Section 4.02, the “Conversion Obligation”). 

(b) Prior to the close of business on the Business Day immediately preceding February 15, 2019, a Holder may surrender all or any portion
of its Securities for conversion during any calendar quarter commencing after the calendar quarter ending on December 31, 2014 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading
Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day.

 (c) Prior to the close of business on the Business Day immediately preceding February 15, 2019, a Holder of the Securities
may surrender all or any portion of its Securities for conversion during the five Business Day period after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of
the Securities, as determined following a request by a Holder of the Securities in accordance with the procedures described below, for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of
Common Stock and the Conversion Rate on each such Trading Day. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price of the Securities unless the Company has requested such determination; and
the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, it shall have no obligation to determine the Trading Price) unless a Holder of the Securities requests in writing that the Company
make such a determination and provides the Company with reasonable evidence that the Trading Price per  

  
 -28- 








 
$1,000 principal amount of the Securities would be less than 98% of the product of the Last Reported Sale Price of Common Stock and the Conversion Rate. At such time, the Company shall instruct
the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of Securities beginning on the next Trading Day
and on each successive Trading Day until the Trading Price per $1,000 principal amount of Securities is greater than or equal to 98% of the product of the Last Reported Sale Price of Common Stock and the Conversion Rate. If the trading price
condition has been met, the Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the trading price condition has been met, the Trading Price per $1,000 principal amount of
Securities is greater than or equal to 98% of the product of the Last Reported Sale Price of Common Stock and the Conversion Rate for such date, the Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee).

 (d) If, prior to the close of business on the Business Day immediately preceding February 15, 2019, the Company elects to: 

(i) issue to all or substantially all holders of Common Stock any rights, options or warrants entitling them, for a period of
not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the five
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 

(ii) distribute to all or substantially all holders of Common Stock, the Company’s assets, securities or rights to
purchase the Company’s securities, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of
announcement of such distribution, 
 then, in either case, the Company shall notify the Holders of the Securities, the Trustee and the Conversion Agent (if
other than the Trustee) at least 50 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender all or any portion of their Securities for conversion at any
time until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and the Company’s announcement that such issuance or distribution will not take place, even if the
Securities are not otherwise convertible at such time. 
 (e) If a transaction or event that constitutes a Fundamental Change or Make-Whole
Fundamental Change occurs prior to the close of business on the Business Day immediately preceding February 15, 2019, regardless of whether a Holder of the Securities has the right to require the Company to repurchase the Securities pursuant to
Section 3.02, or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of the Company’s assets prior to February 15, 2019, pursuant to which Common Stock would
be converted into cash, securities or other assets, then all or any portion of a Holder’s Securities may be surrendered for conversion at any time from or after the date that is 50 Scheduled Trading Days prior to the anticipated effective date
of the transaction (or, if later, 

  
 -29- 








 
the Business Day after the Company gives notice of such transaction) until 50 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a
Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly as practicable following the date the Company
publicly announces such transaction but in no event less than 20 Scheduled Trading Days prior to the anticipated effective date of such transaction; or (ii) if the Company does not have knowledge of such transaction at least 20 Scheduled
Trading Days prior to the anticipated effective date of such transaction, then within two Business Days of the earlier of (x) the date upon which the Company receives notice, or otherwise becomes aware, the anticipated effective date of such
transaction and (y) the actual effective date of such transaction. 
 (f) Prior to the close of business on the Business Day
immediately preceding February 15, 2019, a Holder may surrender all or any portion of its Securities for conversion on any date prior to the Company’s receipt of Shareholder Approval. 

Section 4.02. Settlement Upon Conversion; Conversion Procedures. (a) Subject to this Section 4.02,
Section 4.04 and Section 4.07, upon conversion of any Security, if the Company has not received Shareholder Approval prior to the relevant Shareholder Approval Deadline, the Company shall deliver to the converting Holder, in respect of
each $1,000 principal amount of Securities being converted, a number of shares of Common Stock equal to the Conversion Rate, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with subsection (i) of
this Section 4.02 (any settlement of a conversion of Securities pursuant to this sentence shall be deemed to be a Physical Settlement for purposes of this Indenture and the Securities, unless the context shall otherwise require). Subject to
this Section 4.02, Section 4.04 and Section 4.07, upon conversion of any Security, if the Company has received Shareholder Approval prior to the relevant Shareholder Approval Deadline, the Company shall pay or deliver, as the case may
be, to the converting Holder, in respect of each $1,000 principal amount of Securities being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional
share of Common Stock in accordance with subsection (i) of this Section 4.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of any
fractional share of Common Stock in accordance with subsection (i) of this Section 4.02 (“Combination Settlement”), at its election, as set forth in this Section 4.02. If the Company receives Shareholder
Approval on any day, it shall so notify Holders, the Trustee and the Conversion Agent prior to the close of business on the fourth Business Day following such day; provided that such notice requirement shall be satisfied if the Company
discloses such Shareholder Approval on a Current Report on Form 8-K filed by the Company prior to the fourth Business Day following the day of such Shareholder Approval. 

(i) All conversions for which the relevant Conversion Date occurs on or after February 15, 2019 shall be settled using the
same Settlement Method. Except for conversions of Securities described in the preceding sentence, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but (as long as the Company has received
Shareholder Approval prior to the relevant Shareholder Approval Deadline) the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates. If,


  
 -30- 








 
in respect of any Conversion Date (or with respect to the period beginning on, and including, February 15, 2019 and ending on, and including, the second Scheduled Trading Day immediately
preceding the Maturity Date, as the case may be), the Company has received Shareholder Approval prior to the relevant Shareholder Approval Deadline and elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement
Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee (upon request of the Company), shall deliver such Settlement Notice to converting Holders no later than the close of business on the
Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions of Securities for which the relevant Conversion Date occurs on or after February 15, 2019, no later than February 15, 2019). If the Company
has received Shareholder Approval prior to the relevant Shareholder Approval Deadline and does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect
Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Securities shall be deemed to be
$1,000. Such Settlement Notice shall be prepared by the Company and shall specify the relevant Settlement Method and, in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If
the Company elects Combination Settlement but does not timely notify converting Holders of the Specified Dollar Amount per $1,000 principal amount of Securities, such Specified Dollar Amount will be deemed to be $1,000. 

(ii) With respect to any conversion of Securities for which the Company has received Shareholder Approval prior to the relevant
Shareholder Approval Deadline, the cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of such conversion (the “Settlement Amount”) shall be computed as follows: 

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the
Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Securities being converted a number of shares of Common Stock equal to the Conversion Rate; 

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company
shall pay to the converting Holder in respect of each $1,000 principal amount of Securities being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive Trading Days during the related Observation
Period; and 
 (C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of
such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Securities being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each
of the 40 consecutive Trading Days during the related Observation Period. 

  
 -31- 








 (iii) The Daily Settlement Amounts (if applicable) and the Daily Conversion
Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount
of cash payable in lieu of any fractional share, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash
payable in lieu of fractional shares of Common Stock. 
 (b) Subject to Section 4.02(e), before any Holder of a Security shall be
entitled to convert a Security as set forth above, such Holder shall (i) in the case of a Certificated Security (A) complete and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Conversion Notice attached
to the Form of Security set forth in Exhibit A hereto (a “Conversion Notice”) at the office of the Conversion Agent and state in writing therein the principal amount of Securities to be converted and the name or names (with
addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered by the Company or its agent upon settlement of the Conversion Obligation to be registered, (B) deliver such Security, duly
endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), to the Conversion Agent and (C) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is
not entitled as set forth in subsection (g) of this Section 4.02 and (ii) in the case of a Global Security, comply with the Depositary’s procedures for converting a beneficial interest in a Global Security and, if required, pay
funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in subsection (g) of this Section 4.02. The Trustee (and, if different, the Conversion Agent) shall notify the Company of
any conversion pursuant to this Article 4 on the Conversion Date for such conversion. No Conversion Notice with respect to any Securities may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice
to the Company in respect of such Securities and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 3.02(c). 

If more than one Security shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such
Securities shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered. 

(c) A Security shall be deemed to have been converted immediately prior to the close of business on the Business Day (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (b) above; provided that in the case of a Global Security, no Holder shall be deemed to have complied with the requirements set forth in
subsection (b) above on any Business Day that the Depositary is not open for business. The Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the third Business Day immediately
following the relevant Conversion Date, in the case of Physical Settlement (provided that, with respect to any Conversion Date occurring on or after August 1, 

  
 -32- 








 
2019, the Company shall settle any such conversion on the Maturity Date), or on the third Business Day immediately following the last Trading Day of the Observation Period, in the case of any
other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a
book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation. 

(d) In case any Security shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver
to or upon the written order of the Holder of the Security so surrendered a new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Security, without payment of any
service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result
of the name of the Holder of the new Securities issued upon such conversion being different from the name of the Holder of the old Securities surrendered for such conversion. 

(e) If a Holder submits a Security for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on any
issuance of any shares of Common Stock upon the conversion, unless the tax is due because the Holder requests any shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Company or its stock
transfer 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 Company or its representative receives a sum sufficient to pay any tax that is due by
such Holder in accordance with the immediately preceding sentence. 
 (f) Upon the conversion of an interest in a Global Security, the
Trustee, or the Securities Custodian at the direction of the Trustee, shall make a notation on such Global Security as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of
Securities effected through any Conversion Agent other than the Trustee. 
 (g) Except as described below, the Company shall not make any
separate cash payment for accrued and unpaid interest, if any, upon conversion of Securities. The Company’s settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Security
and accrued and unpaid interest, if any, attributable to the period from, and including, the most recent Interest Payment Date to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but excluding, the
Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Securities into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first
out of the cash paid upon such conversion. Notwithstanding the foregoing, if Securities are submitted for conversion after the close of business on a Regular Record Date and prior to the open of business on the immediately following Interest Payment
Date, Holders of such Securities as of the close of business on such Regular Record Date shall receive the full amount of interest payable on such Securities on such Interest Payment Date notwithstanding the conversion, and Securities surrendered
for conversion 

  
 -33- 








 
after the close of business on a Regular Record Date and prior to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of
interest payable on the principal amount of the Securities being converted; provided that no such payment need be made: 

(i) for conversions following the Regular Record Date immediately preceding the Maturity Date; 

(ii) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to
the corresponding Interest Payment Date; or 
 (iii) to the extent of any Defaulted Amounts, if any Defaulted Amounts exist
at the time of conversion with respect to such Security. 
 As a result of the foregoing, the Company shall pay interest on the Maturity
Date on all Securities converted after the Regular Record Date preceding the Maturity Date, and Holders shall not be required to pay the Company equivalent interest amounts. 

(h) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a
shareholder of record as of the close of business on the relevant Conversion Date (in the case of Physical Settlement) or the last Trading Day of the relevant Observation Period (in the case of Combination Settlement), as the case may be. Upon a
conversion of Securities, such Person shall no longer be a Holder of such Securities surrendered for conversion. 
 (i) The Company shall
not issue any fractional share of Common Stock upon conversion of the Securities and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date
(in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Security surrendered for conversion, if the Company has elected (or is
deemed to have elected) Combination Settlement, the full number of 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. 
 (j) Each conversion shall be deemed to have been effected as to any
Security surrendered for conversion on the Conversion Date; provided, however, that the Person in whose name any shares of Common Stock shall be issuable upon such conversion shall become the holder of record of such shares as of the
close of business on the Conversion Date (in the case of Physical Settlement) or the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). 

Section 4.03. Company to Provide Stock. The Company shall, prior to issuance of any Securities hereunder, and from time to
time as may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock (assuming that at the time of
computation of such number of shares, all such Securities would be converted by a single Holder and that Physical Settlement is applicable).  

  
 -34- 








 All shares of Common Stock delivered upon conversion of the Securities shall be newly issued
shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim. 

The Company shall endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of
Common Stock upon conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange, over-the-counter market or such other market on which the Common Stock is then listed or
quoted; provided, however, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in accordance with the
provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance with the requirements of such automated quotation system or exchange at such time.  

Section 4.04. Adjustment to Conversion Rate Upon a Make-Whole Fundamental Change. (a) If and only to the extent that a
Holder converts its Securities in connection with a Make-Whole Fundamental Change, the Company shall, under the circumstances set forth in this Section 4.04, increase the Conversion Rate for the Securities so surrendered for conversion by a
number of additional shares (the “Additional Shares”), as described below.  
 (b) Upon
surrender of Securities for conversion in connection with a Make-Whole Fundamental Change, the Company shall satisfy its Conversion Obligation by Physical Settlement or, if the Company has received Shareholder Approval prior to the relevant
Shareholder Approval Deadline, the Company shall, at its option, satisfy its Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 4.02. However, if the consideration for the Common
Stock in any Make-Whole Fundamental Change described in clause (c) of the definition of Fundamental Change is composed entirely of cash, for any conversion of the Securities following the Effective Date of such Make-Whole Fundamental Change,
the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount in cash per $1,000 principal amount of converted Securities equal to the Conversion Rate (including any increase to
reflect the Additional Shares as described in this Section 4.04), multiplied by such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the third Business Day following the Conversion
Date. The Company shall notify Holders of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table set
forth in clause (f) below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share
of Common Stock in such Make-Whole Fundamental Change. If holders of Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described 

  
 -35- 








 
in clause (c) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Last
Reported Sale Prices of the Common Stock on each of the five consecutive Trading Days prior to, but excluding, the Effective Date of the Make-Whole Fundamental Change. 

(d) A conversion of Securities by a Holder shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental
Change if the Conversion Notice is received by the Conversion Agent on or after the Effective Date of the Make-Whole Fundamental Change and prior to the close of business on the Business Day immediately preceding the related Fundamental Change
Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the carve-out in subsection (ii) of clause (c) of the definition of Fundamental Change, the 35th Trading Day following
the actual Effective Date of the Make-Whole Fundamental Change). 
 (e) The Stock Prices set forth in the first row of the following
table (i.e., the column headings) shall be adjusted as of any date on which the Conversion Rate is adjusted pursuant to Section 4.05. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment,
multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional
Shares will be adjusted in the same manner, at the same time and for the same events as the Conversion Rate as set forth in Section 4.05.  

(f) The following table sets forth the number of Additional Shares by which the Conversion Rate for the Securities will be increased per
$1,000 principal amount of Securities for each Stock Price and Effective Date set forth below:

 The exact Stock Price and Effective Date may not be set forth in the table above, in which case: 

(i) if the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective Dates in the
table, the number of Additional Shares by which the Conversion Rate for the Securities will be increased shall be determined by straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and
the earlier and later Effective Dates, as applicable, based on a 365-day year; 
 (ii) if the Stock Price is more than
$180.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above), no Additional Shares shall be added to the Conversion Rate; and 

(iii) if the Stock Price is less than $30.50 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table), no Additional Shares shall be added to the Conversion Rate. 

  
 -36- 








 Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount
of Securities exceed 32.7868 shares of Common Stock, subject to adjustment in the same manner, at the same time and for the same events as the Conversion Rate as set forth in Section 4.05. 

Section 4.05. Conversion Rate Adjustments. The Conversion Rate shall be adjusted, without duplication, from time to time by
the Company, upon the occurrence of any of the following events, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Securities participate (other than in the case of a share split or share combination),
at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Securities, in any of the events described in this Section 4.05, without having to convert their Securities as if they held a number
of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Securities held by such Holder. 

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

 
 



 
 where, 
  

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

 Any adjustment made under this Section 4.05(a) shall become effective immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this
Section 4.05(a) is declared but not so paid or made, or any share split or share combination of the type described in this Section 4.05(a) 

  
 -37- 








 
is announced but 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 not to split or combine the outstanding shares of Common Stock, as the case may be, to the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared or such share split or share combination had not been announced. 
 (b) If the Company issues to all or substantially all holders
of its Common Stock any rights, options or warrants entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less
than the average of the Last Reported Sale Prices of the Common Stock for the five consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be
increased based on the following formula: 
  
  
 



 
 where, 
  

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

 Any increase made under this Section 4.05(b) shall be made successively whenever any such rights, options or warrants are
issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the
Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock
actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred. 

  
 -38- 








 For purposes of this Section 4.05(b) and for the purpose of Section 4.01(d)(i), in
determining whether any rights, options 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 for the five consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration
received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property or rights, options
or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 4.05(a)
or Section 4.05(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 4.05(d), (iii) Spin-Offs as to which the provisions set forth below in this
Section 4.05(c) shall apply and (iv) Non-Separate Rights (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company,
the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 
  

 
 



 
 where, 
  

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

 Any increase made under the portion of this Section 4.05(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had not been declared.
Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Security
shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common 

  
 -39- 








 
Stock receive the Distributed Property, the amount of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in
effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 4.05(c) by reference to the actual or when-issued trading market
for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the five consecutive Trading Day period ending on the Trading Day immediately
preceding the Ex-Dividend Date for such distribution. 
 With respect to an adjustment pursuant to this Section 4.05(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, that are, or, when
issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

 
  
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR'	  	=	  	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 (determined by reference to the definition of Last
Reported Sale Price as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first five consecutive Trading Day period after, and including, the Ex-Dividend 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 shall occur on the last Trading Day of the
Valuation Period; provided that in respect of any conversion of Securities during the Valuation Period, references in the portion of this Section 4.05(c) related to Spin-Offs to five Trading Days shall be deemed to be replaced with such
lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the Conversion Date in determining the Conversion Rate. If the Ex-Dividend Date of the Spin-Off is after the fifth Trading Day immediately preceding, and
including, the end of the Observation Period in respect of a conversion of Securities, references in the portion of this Section 4.05(c) related to Spin-Offs to five Trading Days shall be deemed to be replaced, solely in respect of that
conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the last Trading Day of such Observation Period. 

  
 -40- 








 For purposes of this Section 4.05(c) (and subject in all respect to
Section 4.09), rights, options or warrants distributed by the Company, pursuant to a shareholder rights plan to all or substantially all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s
Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred
with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.05(c) (and no
adjustment to the Conversion Rate under this Section 4.05(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment
(if any is required) to the Conversion Rate shall be made under this Section 4.05(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 (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date 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 immediately 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 4.05(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or
purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again
be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock
with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights,
options or warrants 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 Section 4.05(a), Section 4.05(b) and this Section 4.05(c), any dividend or distribution to which this
Section 4.05(c) is applicable that also includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to
which Section 4.05(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend or distribution
of rights, options or warrants to which Section 4.05(b) is applicable (the “Clause B Distribution”), 
 then (1) such
dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 4.05(c) is applicable (the “Clause C Distribution”) and any
Conversion Rate adjustment required by this 

  
 -41- 








 
Section 4.05(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the
Clause C Distribution and any Conversion Rate adjustment required by Section 4.05(a) and Section 4.05(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the
Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be
“outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date” within the meaning of Section 4.05(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date”
within the meaning of Section 4.05(b). 
 (d) If the Company makes any cash dividend or distribution to all or substantially all
holders of the Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  
  





 
 where, 
  

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

 Any increase pursuant to this Section 4.05(d) shall become effective immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution,
to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Security shall receive, for each $1,000 principal amount of Securities, at the same time and upon the same terms as
holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. 

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock, to the extent
that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of 

  
 -42- 








 
the Last Reported Sale Prices of the Common Stock over 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 offer or exchange offer, as the case may be, the Conversion Rate shall be increased based on the following formula: 
  

 
  
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date
such tender or exchange offer expires;
			
	CR'	  	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such
tender or exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares 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 (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such
tender or exchange offer);
			
	OS'	  	=	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or
exchange offer); and
			
	SP'	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 The adjustment to the Conversion Rate under this Section 4.05(e) shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion of Securities
within the 10 Trading Days immediately following, and including, the Trading Day next succeeding 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 Conversion Rate. In addition, if the Trading Day next succeeding the date such tender or exchange offer expires is
after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Securities, references in the preceding paragraph to 10 Trading
Days shall be deemed to be replaced, solely 

  
 -43- 








 
in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer expires to, and
including, the last Trading Day of such Observation Period. 
 (f) Notwithstanding this Section 4.05 or any other provision of this
Indenture or the Securities, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Securities on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as
the record holder of the Common Stock as of the related Conversion Date as described under Section 4.02(j) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this
Section 4.05, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an
unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 
 (g) Except as
stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or
such convertible or exchangeable securities. In addition, the Company shall not adjust the Conversion Rate for guarantees issued in respect of any of its outstanding securities. 

(h) In addition to those adjustments required by subsections (a), (b), (c), (d) and (e) of this Section 4.05, and to the extent
permitted by applicable law and subject to the applicable rules of The NASDAQ Global Select Market, the Company from time to time may increase the Conversion Rate by any amount for any period of at least 20 Business Days if the Board of Directors
has determined that such increase would be in the Company’s best interest. In addition, the Company may (but is not required to) increase the Conversion Rate, as the Board of Directors considers advisable, to avoid or diminish any income tax to
holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for tax purposes. Whenever the Conversion Rate is increased pursuant to
either of the preceding two sentences, the Company shall mail to the Holder of each Security at its last address appearing on the register of the Primary Registrar 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. 
 (i)
Notwithstanding anything to the contrary in this Section 4.05, the Conversion Rate shall not be adjusted: 
 (i) upon
the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common
Stock under any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares
pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 

  
 -44- 








 (iii) upon the issuance of any shares of Common Stock pursuant to any option,
warrant, right (other than rights under a shareholder rights plan as described in Section 4.09) or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection (i) and outstanding as of the date
the Securities were first issued; 
 (iv) solely for a change in the par value of the Common Stock; or 

(v) for accrued and unpaid interest, if any. 

(j) All calculations and other determinations in respect of the Conversion Rate shall be made by the Company to the nearest 1/10,000th of a
share. 
 (k) Whenever the Conversion Rate is adjusted pursuant to this Section 4.05, the Company shall compute the adjusted Conversion
Rate in accordance with this Section 4.05 and shall prepare an Officers’ Certificate setting forth (i) the adjusted Conversion Rate, (ii) the subsection of this Section 4.05 pursuant to which such adjustment has been made,
showing in reasonable detail the facts upon which such adjustment is based, (iii) the calculation of such adjustment and (iv) the date as of which such adjustment is effective, and such Officers’ Certificate shall promptly be
delivered to the Trustee and each Conversion Agent (which certificates shall be conclusive evidence of the accuracy of such adjustment absent manifest error). As soon as practicable after each such adjustment, the Company shall deliver to the
Holders a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate. Unless and until a Responsible Officer of the Trustee and each Conversion Agent shall receive an Officers’ Certificate with
respect to an adjustment of the Conversion Rate, the Trustee and each Conversion Agent may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect. Neither
the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and calculations contained therein, except to exhibit the same to any Holder of Securities desiring inspection
thereof at its office during normal business hours. Simultaneously with an adjustment of the Conversion Rate, the Company shall disseminate a press release detailing the new Conversion Rate and other relevant information. 

(l) For purposes of this Section 4.05, the number of shares of Common Stock at any time outstanding shall not include shares held in the
treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock. 
 (m) The Company shall not take any voluntary action that would result in an adjustment pursuant to
any of the provisions described in clauses (b) through (e) of Section 4.05 or Section 4.04 without complying, if applicable, with the shareholder approval rules of the NASDAQ Global Stock Market (including NASDAQ Stock Market
Rule 5635, which requires shareholder approval of certain issuances of Common Stock) or any similar rule of any other stock exchange on which the Common Stock is listed at the relevant time. 

  
 -45- 








 Section 4.06. Adjustments of Prices. Whenever any provision of this Indenture
requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock
Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the
Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the relevant period. 
 Section 4.07.
Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. (a) In the case of: 
 (i) any
recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination), 

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

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s
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, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Securities shall be changed into a right to
convert such principal amount of Securities 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
Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of Reference Property
that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the
Trustee a supplemental indenture permitted under Section 10.01(f) providing for such change in the right to convert each $1,000 principal amount of Securities; provided, however, that at and after the effective time of the Merger
Event, if the Company has received Shareholder Approval prior to the relevant Shareholder Approval Deadline, (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be,
upon conversion of Securities in accordance with Section 4.02 and (B)(I) any amount payable in cash upon conversion of the Securities in accordance with Section 4.02 shall continue to be payable in cash, (II) any shares of Common Stock
that the Company would have been required to deliver upon conversion of the Securities in accordance with Section 4.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common
Stock would have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. If the Merger Event causes the Common Stock to be converted into, or exchanged for, the
right to receive more than a single type of consideration 

  
 -46- 








 
(determined based in part upon any form of shareholder election), then the Reference Property into which the Securities will be convertible shall be deemed to be (i) the weighted average of
the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (ii) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually
received by the holders of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the weighted average as soon as practicable after the determination is made. 

If the holders of Common Stock receive only cash in such Merger Event, then for all conversions of Securities that occur after the effective
date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Securities shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased pursuant to
Section 4.04), multiplied by the price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately
following the Conversion Date. 
 Such supplemental indenture described in the second immediately preceding paragraph shall provide for
adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 4. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including
cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional
provisions to protect the interests of the Holders of the Securities 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 3. 
 (b) In the event the Company shall execute a supplemental indenture pursuant
to subsection (a) of this Section 4.07, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise the
Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the
execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the register of the Primary Registrar provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not
affect the legality or validity of such supplemental indenture. 
 (c) The Company shall not become a party to any Merger Event unless its
terms are consistent with this Section 4.07. None of the foregoing provisions shall affect the right of a Holder of Securities to convert its Securities into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as
applicable, as set forth in Section 4.01 and Section 4.02 prior to the effective date of such Merger Event. 
 (d) The above
provisions of this Section 4.07 shall similarly apply to successive Merger Events. 

  
 -47- 








 Section 4.08. Cancellation of Converted Securities. All Certificated
Securities delivered for conversion shall be delivered to the Trustee or its agent to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in this Indenture. Upon conversions of beneficial interests in any
Global Security, the Trustee or the Securities Custodian, at the direction of the Trustee, shall reduce the aggregate principal amount of outstanding Securities represented by such Global Security to reflect the conversion.  

Section 4.09. Shareholders Rights. If the Company has a shareholder rights plan in effect upon conversion of the
Securities, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such
legends, if any, in each case as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time (such rights prior to separation from the Common Stock, “Non-Separate
Rights”). However, if prior to any conversion the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan so that the Holders would not be entitled to receive
any rights in respect of Common Stock, if any, issuable upon conversion of the Securities, the Conversion Rate shall be increased at the time of separation as if the Company distributed to all or substantially all holders of Common Stock shares of
Capital Stock of the Company, evidences of its indebtedness, other assets or property or rights, options or warrants to acquire its Capital Stock or other securities as provided in Section 4.05(c), subject to decrease in the event of the
expiration, termination or redemption of such rights. A distribution of rights pursuant to such a shareholder rights plan shall not trigger a Conversion Rate adjustment pursuant to Section 4.05(c) if Holders of the Securities participate in
such distribution on an as-converted basis in accordance with the first paragraph of Section 4.05. 
 Section 4.10.
Trustee’s Disclaimer. The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the
correctness of any such adjustment, and shall be protected in relying upon, the Officers’ Certificate that the Company is obligated to deliver to the Trustee pursuant to Section 4.05(k). The Trustee makes no representation as to the
validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure to comply with any provisions of this Article 4. The Trustee and the Conversion Agent (if
other than the Trustee) shall have no responsibility for determination of the Daily Settlement Amounts (if applicable) or the Daily Conversion Values (if applicable). In addition, in no event shall the Trustee or Conversion Agent be responsible for
making any calculations under this Indenture or for determining amounts to be paid or for monitoring any Stock Price. For the avoidance of doubt, the Trustee and Conversion Agent shall rely conclusively on the calculations and information provided
to them by the Company as to the Daily VWAP, Trading Price, Daily Conversion Value, Daily Settlement Amount and Last Reported Sale Price. Nor shall the Trustee or Conversion Agent be charged with knowledge of or have any duties to monitor any
Measurement Period or Observation Period. 
 The Trustee shall not be under any responsibility to determine the correctness of any
provisions contained in any supplemental indenture executed pursuant to Section 6.01, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers’ Certificate with respect
thereto which the Company is obligated to file with the Trustee pursuant to Section 6.01.

 ARTICLE 5 

COVENANTS 

Section 5.01. Payment on the Securities. The Company shall promptly make all payments in respect of the Securities on the
dates and in the manner provided in the Securities and this Indenture. Principal (including the Fundamental Change Repurchase Price, if applicable) of and interest on the Securities shall be considered paid on the date it is due, if the Paying Agent
(if other than the Company or an Affiliate thereof) holds as of 11:00 a.m., New York City time, on the due date money, deposited by the Company or an Affiliate thereof in immediately available funds, designated for and sufficient to pay all
principal (including the Fundamental Change Repurchase Price) and interest then due on the Securities.  
 Payment of the
principal of and interest on the Securities shall be made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York (which shall initially be an office or agency of the Trustee in the
Borough of Manhattan, The City of New York); provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address appears in the Register;
provided further that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to
the Company and the Trustee at least 10 Business Days prior to the payment date, it being understood that as long as the Securities are Global Securities, payment will be made by wire transfer to DTC.  

Section 5.02. SEC Reports and Rule 144A Information Requirement. (a) The Company shall file with the Trustee within 15 days
after the same are required to be filed with the SEC, copies of any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule
12b-25 under the Exchange Act). Any such document or report that the Company files with the SEC via the EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section 5.02 at the time such documents are filed via EDGAR.

 (b) Delivery of such reports, information and documents 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 rely exclusively on Officers’ Certificates). 
 (c) At any time the Company is not subject to Section 13 or 15(d) of
the Exchange Act, the Company shall, so long as any of the Securities 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, upon written request, any Holder, beneficial owner or prospective purchaser of such Securities or any shares

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

Section 5.03. Compliance Certificates. (a) The Company shall deliver to the Trustee, (i) within 120 days after
the end of each fiscal year during which any Securities were outstanding and (ii) upon written request from the Trustee, an Officers’ Certificate stating whether or not the signer thereof knows of any Default or Event of Default that

activities of the Company and the Company’s performance under this Indenture and that the Company has complied with all conditions and covenants under this Indenture. For purposes of this Section 5.03, such compliance shall be determined
without regard to any period of grace or requirement of notice provided under this Indenture. If the officer of the Company signing such Officers’ Certificate has knowledge of such a Default or Event of Default, the Officers’ Certificate
shall describe any such Default or Event of Default and its status.  
 (b) The Company shall, so long as any of the Securities are
outstanding, deliver to the Trustee, forthwith, and in any event within five days, upon any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto.

necessary to preserve and keep in full force and effect its corporate existence.

Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law
which would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

 Section 5.07. Additional Amounts. (a) If the Company
consolidates with or merges into, or sells, conveys, transfers or leases all or substantially all of the Company’s properties and assets to, another Person pursuant to Section 6.01, and the Successor Company is not organized and existing
under the laws of the United States of America, any State thereof or the District of Columbia, then all payments and deliveries made by, or on behalf of, the Successor Company under or with respect to the Securities, including, but not limited to,

Successor Company is, for tax purposes, organized or resident or doing business or through which payment is made or deemed made (or any political subdivision or taxing authority thereof or therein) (each, as applicable, a “Relevant Taxing
Jurisdiction”), unless such withholding or deduction is required by law or by the official interpretation or administration thereof. In the event that any such withholding or deduction is so required, the Successor Company shall pay such
additional amounts (the “Additional Amounts”) as may be necessary to ensure that the net amount received by the beneficial owner after such withholding or deduction (and after deducting or withholding any Taxes on the Additional
Amounts) shall equal the amounts that would have been received by such beneficial owner had no such withholding or deduction been required; provided that no Additional Amounts shall be payable: 

(i) for or on account of: 

(A) any Tax that would not have been imposed but for: 

(1) the existence of any present or former connection between the Holder or beneficial owner of such Security and the Relevant
Taxing Jurisdiction, other than merely holding such Security or the receipt of payments thereunder, including, without limitation, such Holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Taxing
Jurisdiction or treated as a resident thereof or being or having been physically present or engaged in a trade or business therein or having or having had a permanent establishment therein; 

(2) the presentation of such Security (in cases in which presentation is required) more than 30 days after the later of the

conversion of such Security became due and payable pursuant to the terms thereof or was made or duly provided for; or 
 (3)
the failure of the Holder or beneficial owner to comply with a timely request from the Successor Company to provide 

  
 -52- 








 
certification, information, documents or other evidence concerning such Holder’s or beneficial owner’s nationality, residence, identity or connection with the Relevant Taxing
Jurisdiction, or to make any declaration or satisfy any other reporting requirement relating to such matters, if and to the extent that due and timely compliance with such request is required by statute, regulation or administrative practice of the
Relevant Taxing Jurisdiction in order to reduce or eliminate any withholding or deduction as to which Additional Amounts would have otherwise been payable to such Holder or beneficial owner; 

(B) any estate, inheritance, gift, sale, transfer, excise, personal property or similar Tax; 

(C) any Tax that is payable otherwise than by withholding or deduction from payments under or with respect to the Securities;

 (D) United States backup withholding; 

(E) any Taxes that could have been avoided by the presentation (where presentation is required) of such Security to another
Paying Agent;

withheld pursuant to the European Council Directive 2003/48/EC or any other directive implementing the conclusions of the ECOFIN meeting of November 26-27, 2000 on the taxation of savings income or any law implementing or complying with, or
introduced in order to conform to, such directive; 
 (G) any Tax required by sections 1471 through 1474 of the United States
Internal Revenue Code of 1986, as amended (“FATCA”), any current or future Treasury Regulations or rulings promulgated thereunder, any law, regulation or other official guidance enacted in any jurisdiction implementing FATCA, any
intergovernmental agreement between the United States and any other jurisdiction to implement FATCA or any law enacted by such other jurisdiction to give effect to such agreement, or any agreement with the U.S. Internal Revenue Service under FATCA;
or 
 (H) any combination of Taxes referred to in the preceding clauses (A), (B), (C), (D), (E), (F) or (G), or 

(ii) with respect to any payment of the principal of (including the Fundamental Change Repurchase Price, if applicable) and
interest on, such Security or the delivery of Common Stock or other Reference Property and/or payments of cash, in each case, upon conversion of such Security to a Holder, if the Holder is a fiduciary, partnership or person other than the sole
beneficial owner of that payment to the extent that such payment would be required to be included in the income under the laws of the Relevant Taxing Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a
partner or member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner, member or beneficial owner been the Holder thereof. 

  
 -53- 








 (b) If the Successor Company is required to make any deduction or withholding from any payments
with respect to the Securities, the Successor Company will deliver to the Trustee official tax receipts evidencing the remittance to the relevant tax authorities of the amounts so withheld or deducted or other evidence reasonably satisfactory to the
Trustee. 
 (c) Any reference in this Indenture or the Securities in any context to the delivery of Common Stock or other Reference Property
and/or payments of cash, in each case, upon conversion of any Security or the payment of principal of (including the Fundamental Change Repurchase Price, if applicable) and interest on, any Security or any other amount payable with respect to such
Security, shall be deemed to include payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to this Section 5.07.

directly or indirectly, consolidate with or merge into any other Person (in a transaction in which the Company is not the surviving corporation) or sell, convey, transfer or lease all or substantially all of its properties and assets to another
Person, unless:  
 (a) in case the Company shall consolidate with or merge into another Person (in a transaction in which the
Company is not the surviving corporation) or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, the Person formed by such consolidation or into which the Company is merged or the Person which
acquires by sale, conveyance or transfer, or which leases, all or substantially all of the properties and assets of the Company (in each case, the “Successor Company”) shall: 

(i) be (A) a corporation or limited liability company organized and validly existing under the laws of the United States
of America, any State thereof or the District of Columbia, or (B) a corporation or entity treated as a corporation for U.S. federal income tax purposes organized and existing under the laws of the Islands of Bermuda, the Netherlands, Belgium,

 (ii) expressly assume, by an indenture supplemental hereto, executed and delivered
to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of and interest on all the Securities and the performance or observance of every covenant of this Indenture on the part of the Company to be performed
or observed (including, for the avoidance of doubt, the covenant to pay Additional Amounts, as set forth in Section 5.07) and the conversion rights shall be 

  
 -54- 








 
provided for in accordance with Article 4, by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee, by such Successor Company (if other than the
Company); 
 (b) immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time
or both, would become an Event of Default, shall have happened and be continuing; and 
 (c) the Company has delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture,
comply with this Article 6 and that all conditions precedent herein provided for relating to such transaction have been complied with. 

Section 6.02. Successor Substituted. Upon any consolidation of the Company with, or merger of the Company into, any other
Person or any sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company in accordance with Section 6.01, there shall be an adjustment to the Conversion Rate and the Successor Company shall
succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such Successor Company had been named as the Company herein, and thereafter, except in the case of a lease,
the Company shall be relieved of all obligations and covenants under this Indenture and the Securities. 
 ARTICLE 7 

DEFAULT AND REMEDIES 

Section 7.01. Events Of Default. An “Event of Default” shall occur if: 

(1) the Company fails to pay the principal of any Security when due and payable at its stated maturity, upon any required repurchase, upon
declaration of acceleration or otherwise; 
 (2) the Company fails to pay the interest on any Security when due and payable and such failure
continues for a period of 30 days; 
 (3) the Company fails to convert any Security in accordance with this Indenture upon exercise of a
Holder’s conversion right and such failure continues for 5 days; 
 (4) the Company fails to provide timely notice pursuant to
Section 3.02(a), Section 3.02(b), Section 4.01(d), Section 4.01(e) or Section 4.04(b), in each case when due and such failure continues for 30 days; 

(5) the Company fails to comply with its obligations set forth in Article 6; 

(6) the Company fails to perform any other agreement required of it in this Indenture or the Securities and such failure continues for 60 days
after written notice is given in accordance with the immediately succeeding paragraph; 

  
 -55- 








 (7) any indebtedness for money borrowed by the Company or any of its Significant Subsidiaries in
an aggregate outstanding principal amount in excess of $15,000,000 is not paid at final maturity or upon acceleration, and such indebtedness is not discharged, or such acceleration is not cured or rescinded, within 30 days after written notice is
given in accordance with the immediately succeeding paragraph; 
 (8) the Company or any Significant Subsidiary, pursuant to or within the
meaning of any Bankruptcy Law: 
 (A) commences a voluntary case or proceeding; 

(B) consents to the entry of an order for relief against it in an involuntary case or proceeding; 

(C) consents to the appointment of a Custodian of it or for all or substantially all of its property; or 

(D) makes a general assignment for the benefit of its creditors; or 

(9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) is for relief against the Company or any Significant Subsidiary in an involuntary case or proceeding; 

(B) appoints a Custodian of the Company or any Significant Subsidiary or for all or substantially all of the property of the
Company or any Significant Subsidiary; or 
 (C) orders the liquidation of the Company or any Significant Subsidiary; 

and in each case the order or decree remains unstayed and in effect for 60 consecutive days. 

A default under clause (6) or clause (7) above is not an Event of Default until the Trustee notifies the Company, or the Holders of
at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee, in writing of the default, and the Company does not cure the default within 60 days (in the case of clause (6)) or 30 days (in the
case of clause (7)) after receipt of such notice. The notice given pursuant to this Section 7.01 must specify the default, demand that it be remedied and state that the notice is a “Notice of Default.” When any default under this
Section 7.01 is cured, it ceases. 
 The Trustee shall not be charged with knowledge of any Event of Default unless written notice
thereof shall have been actually received by a Responsible Officer at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder. 

Section 7.02. Acceleration. If an Event of Default (other than an Event of Default specified in clause (8) or
(9) of Section 7.01) occurs and is continuing, the Trustee may, by 

  
 -56- 








 
notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid
principal to the date of acceleration on the Securities then outstanding (if not then due and payable) to be due and payable upon any such declaration, and the same shall become and be immediately due and payable. If an Event of Default specified in
clause (8) or (9) of Section 7.01 occurs, all unpaid principal of the Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any
Holder. After any acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the Securities may, except with respect to the nonpayment of principal or interest or with respect to
the failure to pay and/or deliver the consideration due upon conversion, rescind and annul such acceleration by notice to the Trustee if (a) all existing Events of Default, other than the non-payment of accelerated principal, have been cured or
waived; (b) to the extent the payment of such interest is lawful, interest (calculated at the rate per annum borne by the Securities plus one percent) on overdue installments of interest and overdue principal, which has become due otherwise
than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under
Section 8.07 have been made. No such rescission shall affect any subsequent default or impair any right consequent thereto.  

Section 7.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated
to, pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.  

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. All available remedies are cumulative to the extent permitted by law. 
 Section 7.04. Additional Interest.
(a) Notwithstanding anything in this Indenture or in the Securities to the contrary, to the extent the Company elects, the sole remedy for an Event of Default during the first 180 days after the occurrence of an Event of Default relating to the
Company’s failure to comply with its obligations as set forth in Section 5.02(a), shall after the occurrence of such an Event of Default consist exclusively of the right to receive Additional Interest on the Securities at a rate equal to
0.25% per annum of the principal amount of the Securities outstanding for each day during which such Event of Default is continuing during the 90-day period beginning on, and including, the date on which such an Event of Default first occurs;
and 0.50% per annum of the principal amount of the Securities outstanding for each day during which such Event of Default is continuing during the 90-day period beginning on, and including, the 91st day following, and including, the date on
which such an Event of Default first occurs. Additional Interest payable pursuant to this Section 7.04 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 2.06(d) or Section 2.06(e). 

  
 -57- 








 (b) If the Company so elects, such Additional Interest shall be payable in the same manner and on
the same dates as the stated interest payable on the Securities. On the 181st day after such Event of Default (if such Event of Default is not cured or waived prior to such 181st day), the Securities will be subject to acceleration as provided in
Section 7.02. This Section 7.04 shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. If the Company does not elect to pay Additional Interest following an Event of Default in accordance with
this Section 7.04, or if it so elects but fails to pay the Additional Interest when due, the Securities shall be immediately subject to acceleration as provided in Section 7.02. To elect to pay Additional Interest as the sole remedy during
the first 180 days after the occurrence of an Event of Default relating to the failure to comply with the reporting obligations in accordance with subsection (a) of this Section 7.04 and this subsection (b), the Company must notify all
Holders of the Securities, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the Company’s failure to timely give such notice or if the Company gives such notice but does not pay the
Additional Interest when due, the Securities shall be immediately subject to acceleration as provided in Section 7.02. 

Section 7.05. Waiver of Defaults and Events of Default. Subject to Section 7.08 and Section 9.02, the Holders of
a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may waive an existing default or Event of Default and its consequence, except (a) a default or Event of Default in the payment of the principal
of or interest on any Security, (b) a failure by the Company to convert any Securities in accordance with the provisions of the Securities and this Indenture or (c) any default or Event of Default in respect of any provision of this
Indenture or the Securities that, under Section 10.02, cannot be modified or amended without the consent of the Holder of each Security affected. When a default or Event of Default is waived, it is cured and ceases.  

Section 7.06. Control by Majority. The Holders of a majority in aggregate principal amount of the outstanding Securities
will 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 the Securities. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture, that the Trustee, in its sole discretion, determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability
unless the Trustee is offered reasonable indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.  

Section 7.07. Limitations on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Securities
(except actions for the enforcement of payment of the principal or interest on any Security on or after the applicable due date or the right to convert the Securities in accordance with Article 4) unless:  

 

	 	(1)	the Holder has previously given the Trustee written notice of a continuing Event of Default; 

  

	 	(2)	the Holders of at least 25% in aggregate principal amount of the Securities then outstanding have made a written request and have offered to the Trustee reasonable indemnity satisfactory to the Trustee to institute such
proceeding as Trustee; and 

  

	 	(3)	the Trustee has failed to institute such proceeding within 60 days after such notice, request and offer, and has not received from the Holders of a majority in aggregate principal amount of the Securities then
outstanding a direction inconsistent with such request within 60 days after such notice, request and offer. 


  
 -58- 








 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a
preference or priority over such other Holder. 
 Section 7.08. Rights of Holders to Receive Payment and to Convert. Each Holder
shall have the right to receive payment or delivery, as the case may be, of (a) the principal (including the Fundamental Change Repurchase Price) of, (b) accrued and unpaid interest, if any, on, and (c) the consideration due upon
conversion of, its Securities, on or after the respective due dates expressed or provided for in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, and such right to receive payment or
delivery, as the case may be, on or after such respective dates shall not be impaired or affected without the consent of such Holder. 

Section 7.09. Collection Suit By Trustee. If an Event of Default in the payment of principal or interest specified in
clause (1) or (2) of Section 7.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount of principal
and accrued interest remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal and on overdue installments of interest, in each case at the rate per annum borne by the Securities plus one
percent and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.  

Section 7.10. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be
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 the Holders allowed in any judicial proceedings
relative to the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the
same, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 8.07, and to the extent that such payment of the
reasonable compensation, expenses, disbursements and advances 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, money,
securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to


  
 -59- 








 
authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 7.11. Priorities. If the Trustee collects any money pursuant to this Article 7, it shall pay out the money in the
following order: 
 FIRST, to the Trustee for amounts due under Section 8.07; 

SECOND, to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any
kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and 
 THIRD, to the Company or
such party as a court of competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 7.11. 
 Section 7.12. Undertaking For Costs. 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, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of
the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section 7.12 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 7.07, or a suit by Holders of more than 10% in aggregate principal amount of the Securities then outstanding. 

 ARTICLE 8 

TRUSTEE 

Section 8.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise
such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of his or her own affairs.  

(b) Except during the continuance of an Event of Default: 

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements 

  
 -60- 








 
of this Indenture. The Trustee, however, shall examine any certificates and opinions which by any provision hereof are specifically required to be delivered to the Trustee to determine whether or
not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 

(c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful

it believes to be authorized or within its rights or powers conferred upon it by this Indenture. 
 (e) The Trustee may consult with counsel
of its selection, and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any such action taken, omitted or suffered by it hereunder in good faith and in
accordance with the advice or opinion of such counsel. 
 (f) 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, note, other evidence of indebtedness 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 sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

(g) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer has actual knowledge

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder. 

(i) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of
officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in
any such certificate previously delivered and not superseded. 
 (j) In no event shall the Trustee be responsible or liable for special,
punitive, indirect or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of
action. 
 Section 8.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or an Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 8.10. 

  
 -62- 








 Section 8.04. Trustee’s Disclaimer. The Trustee shall not be responsible
for and makes no representation as to the validity, priority or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities or any money paid to the Company or upon the
Company’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent (other than the Trustee) and it shall not be responsible for any statement or recital
herein or any statement in the Securities or any other document in connection with the sale of the Securities or pursuant to this Indenture other than its certificate of authentication.  

Section 8.05. Notice of Default or Events of Default. If a Default or an Event of Default occurs and is continuing and if
it is known to the Trustee, the Trustee shall mail to each Holder notice of the Default or Event of Default within 90 days after it occurs. However, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in
good faith determines that withholding notice is in the interests of Holders, except in the case of a Default or an Event of Default in (a) payment of the principal of or interest on any Security or (b) payment or delivery, as the case may
be, of the consideration due upon conversion. 
 Section 8.06. [Reserved]. 

Section 8.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation (as
agreed to from time to time by the Company and the Trustee in writing) for its services (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company shall reimburse the
Trustee promptly upon request for all reasonable disbursements, expenses and advances incurred or made by it in addition to the compensation for its services. Such expenses may include the reasonable compensation, disbursements and expenses of the
Trustee’s agents and counsel.  
 The Company shall indemnify each of the Trustee and any predecessor Trustee against any and
all losses, liabilities, damages, claims or expenses (including taxes, other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 8.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other
Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee, upon receiving written notice thereof, shall notify the Company promptly of any claim for which it may seek indemnity. Failure
by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay
the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its written consent, which consent shall not be unreasonably withheld. 

The Company need not reimburse the Trustee for any expense or indemnify it against any loss or liability incurred by it resulting from its
negligence or willful misconduct. 
 To secure the Company’s payment obligations in this Section 8.07, the Trustee shall have a
senior claim to which the Securities are hereby made subordinate on all money or property held or collected by the Trustee, except such money or property held in trust to pay the principal of, interest on, and amounts due upon conversion of, the
Securities. 

  
 -63- 








 When the Trustee incurs expenses or renders services after an Event of Default specified in
clause (7) or (8) of Section 7.01 occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.
The obligations of the Company under this Section 8.07 shall survive the termination or satisfaction and discharge of this Indenture or the resignation or removal of the Trustee for any reason. 

Section 8.08. Replacement of Trustee. The Trustee may resign by so notifying the Company in writing. The Holders of a
majority in aggregate principal amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee and the Company in writing and may, with the Company’s written consent, appoint a successor Trustee. The Company may
remove the Trustee if:  
  

	 	(1)	the Trustee fails to comply with Section 8.10; 

  

	 	(2)	the Trustee is adjudged a bankrupt or an insolvent or relief is entered with respect to the Trustee under any Bankruptcy Law; 

  

	 	(3)	a receiver or other public officer takes charge of the Trustee or its property; or 

  

	 	(4)	the Trustee becomes incapable of acting. 

 If the Trustee resigns or is removed or if a vacancy
exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. The resignation or removal of a Trustee shall not be effective until a successor Trustee shall have delivered the written acceptance of its
appointment as described below. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Company or the Holders of 10% in principal amount of the Securities then outstanding may petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Company. 

If the Trustee fails to comply with Section 8.10, any Holder who has been a Holder for at least six months may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 A successor Trustee shall
deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee (provided that all sums owing
to the Trustee hereunder have been paid) and be released from its obligations (exclusive of any liabilities that the retiring Trustee may have incurred while acting as Trustee) hereunder, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder.  

  
 -64- 








 A retiring Trustee shall not be liable for the acts or omissions of any successor Trustee after
its succession. 
 Notwithstanding replacement of the Trustee pursuant to this Section 8.08, the Company’s obligations under
Section 8.07 shall continue for the benefit of the retiring Trustee. 
 Section 8.09. Successor Trustee by Merger,
Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust assets (including the administration of this Indenture) to, another corporation, by sale or otherwise, the resulting,
surviving or transferee corporation, without any further act, shall be the successor Trustee, provided such transferee corporation shall qualify and be eligible under Section 8.10. Such successor Trustee shall promptly mail notice of its
succession to the Company and each Holder.  
 Section 8.10. Eligibility; Disqualification. The Trustee (or its
parent holding company) shall have a combined capital and surplus of at least $50,000,000. If at any time the Trustee shall cease to satisfy such requirement, it shall resign immediately in the manner and with the effect specified in this Article
8. 
 Section 8.11. [Reserved]. 

ARTICLE 9 

SATISFACTION AND DISCHARGE OF INDENTURE 

Section 9.01. Satisfaction And Discharge Of Indenture. 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 Securities theretofore
authenticated and delivered (other than Securities that have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.07) have been delivered to the Trustee for cancellation; or (ii) the Company has
deposited with the Trustee or delivered to Holders, as applicable, after the Securities have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash, shares of Common Stock or
a combination thereof, as applicable, solely to satisfy the Company’s Conversion Obligation, sufficient to pay all of the outstanding Securities and all other sums due and 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 8.07 shall
survive and, if money shall have been deposited with the Trustee pursuant to paragraph (a)(ii) of this Section 9.01, the provisions of Section 9.02 and Section 9.04 shall survive until the Securities have been paid in full. 

Section 9.02. Application of Trust Money. Subject to the provisions of Section 9.03, the Trustee or a Paying Agent shall hold
in trust, for the benefit of the Holders, all money and shares of Common Stock deposited with it pursuant to Section 9.01 and shall apply the deposited 

  
 -65- 








 
money and shares of Common Stock in accordance with this Indenture and the Securities to the payment or delivery, as the case may be, of the principal of, and interest on, and the consideration
due upon conversion of, the Securities; provided that such money and shares of Common Stock need not be segregated from other funds except to the extent required by law. 

Section 9.03. Repayment to Company. The Trustee and each Paying Agent shall promptly pay to the Company upon request any
excess money or shares of Common Stock (i) deposited with them pursuant to Section 9.01 and (ii) held by them at any time.  

The Trustee and each Paying Agent shall pay to the Company upon request any money or shares of Common Stock held by them for the payment or
delivery, as the case may be, of principal, interest or amounts due upon conversion that remains unclaimed for two years after a right to such money or shares of Common Stock has matured; provided, however, that the Trustee or such
Paying Agent, before being required to make any such payment or delivery, may at the expense of the Company cause to be mailed to each Holder entitled to such money or shares of Common Stock notice that such money or shares of Common Stock remains
unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such mailing, any unclaimed balance of such money or shares of Common Stock then remaining will be repaid or delivered to the Company. After payment
or delivery to the Company, Holders entitled to money or share of Common Stock must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person. In the absence of a written request from
the Company to return unclaimed funds or shares to the Company, the Trustee shall from time to time deliver all unclaimed funds or shares to or as directed by applicable escheat authorities, as determined by the Trustee in its sole discretion, in
accordance with the customary practices and procedures of the Trustee. Any unclaimed funds or shares held by the Trustee pursuant to this Section 9.03 shall be held uninvested and without any liability for interest. 

Section 9.04. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or shares of Common Stock in
accordance with Section 9.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations
under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.01 until such time as the Trustee or such Paying Agent is permitted to apply all such money or shares of Common
Stock in accordance with Section 9.02; provided, however, that if the Company has made any payment or delivery, as the case may be, of the principal of, interest on, or amounts due upon conversion of, any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive any such payment or delivery from the money or shares of Common Stock held by the Trustee or such Paying Agent.  

ARTICLE 10

in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to
enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 

Section 10.02. With Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities with the
written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. The Holders of at least a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a
particular instance by the Company with any provision of this Indenture or the Securities without notice to any Holder. However, notwithstanding the foregoing but subject to Section 10.04, without the written consent of each Holder affected, an
amendment, supplement or waiver, including a waiver pursuant to Section 7.05, may not: 
 (a) change the stated maturity of the
principal of, or interest on, any Security; 
 (b) reduce the principal amount of or interest on any Security;

Indenture or the waiver of certain defaults under this Indenture; 
 (k) change the provisions of Section 5.07 in a manner adverse to
the Holders; or 
 (l) modify provisions of this Section 10.02 or Section 7.05 in a manner adverse to the Holders. 

It shall not be necessary for the consent of the Holders under this Section 10.02 to approve the particular form of any proposed
amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 Upon the request of the
Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as
aforesaid, and upon receipt by the Trustee of the documents described in Section 10.06 and Section 11.04, the Trustee shall join with the Company in the execution of such amended or supplemental indenture unless such amended or
supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental
indenture. 
 After an amendment, supplement or waiver under this Section 10.02 becomes effective, the Company shall mail to the
Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment,
supplement or waiver. 
 Section 10.03. [Reserved]. 

  
 -68- 








 Section 10.04. Revocation and Effect of Consents. Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even
if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment,
supplement or waiver becomes effective. 
 After an amendment, supplement or waiver becomes effective, it shall bind every Holder,
unless it makes a change described in any of clauses (a) through (l) of Section 10.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a
Security or portion of a Security that evidences the same debt as the consenting Holder’s Security. 
 Section 10.05.
Notation on or Exchange of Securities. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Security thereafter authenticated. The Company in exchange for all Securities may issue and the Trustee shall,
upon receipt of a Company Order, authenticate new Securities that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or
waiver.  
 Section 10.06. Trustee to Sign Amendments, Etc. The Trustee shall sign any amendment or supplemental
indenture authorized pursuant to this Article 10 if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not
sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be provided with and, subject to Section 8.01, shall be fully protected in relying upon in addition to the documents required by
Section 11.04, an Officers’ Certificate and an Opinion of Counsel stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or supplement indenture until the
Board of Directors approves it.  
 Section 10.07. Effect of Supplemental Indentures. Upon the execution of any
supplemental indenture under this Article 10, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter
authenticated and delivered hereunder shall be bound thereby.

 Notwithstanding any other provision of this Indenture or any Security, where this Indenture or
any Security provides for notice of any event or any other communication to a Holder of a Global Security (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depositary (or its designee) pursuant to the standing

Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the
identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that Instructions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent
by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and
confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s
reliance upon and compliance with such Instructions notwithstanding such Instructions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (a) to assume all risks arising out of the use of Electronic Means to
submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; and (b) to notify the Trustee immediately upon learning of

which record date shall not be more than 30 days prior to the date of the commencement of solicitation of such action. Notwithstanding the provisions of Section 10.04, if a record date is fixed, those Persons who were Holders of Securities at
the close of business on such record date (or their duly designated proxies), and only those Persons, shall be entitled to take such action by vote or consent or to revoke any vote or consent previously given, whether or not such Persons continue to
be Holders after such record date.  
 Section 11.06. Rules By Trustee, Paying Agent, Registrar And Conversion Agent.
The Trustee may make reasonable rules (not inconsistent with the terms of this Indenture) for action by or at a meeting of Holders. Any Registrar, Paying Agent or Conversion Agent may make reasonable rules for its functions.

 Section 11.08. Governing Law; Jurisdiction. THIS INDENTURE AND THE SECURITIES,

 [FORM OF REVERSE OF SECURITY] 

AEGERION PHARMACEUTICALS, INC. 

2.00% CONVERTIBLE SENIOR NOTES DUE 2019 

This Security is one of a duly authorized issuance of Securities of the Company, designated as its 2.00% Convertible Senior Notes due
2019 (the “Securities”), limited in aggregate principal amount of up to $300,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Securities purchased by the Initial Purchasers pursuant to the
exercise of their option to purchase additional Securities as set forth in the Purchase Agreement), all issued or to be issued under and pursuant to an Indenture dated as of August 15, 2014 (the “Indenture”), between the
Company and The Bank of New York Mellon Trust Company, N.A. (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 Securities. Additional Securities may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. 

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all Securities may be
declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Securities 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. In case an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company, the principal of all Securities then outstanding shall ipso facto
become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder,  
 Subject
to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a
Security to a Paying Agent to collect such payments in respect of the Security. 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
Securities, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time outstanding, evidenced as in the Indenture provided, to execute supplemental
indentures modifying the terms of the Indenture and the Securities as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Securities at the time
outstanding may on behalf of the Holders of all of the Securities waive any past Default or Event of Default under the Indenture and its consequences. 

The Securities 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 

  
 A-6 








 
Indenture, Securities may be exchanged for a like aggregate principal amount of Securities 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 transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Securities issued upon such exchange of Securities being different from
the name of the Holder of the old Securities surrendered for such exchange. 
 The Securities 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 Securities or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the
Fundamental Change Repurchase Price. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, prior to
the close of business on the Business Day immediately preceding February 15, 2019 only upon the occurrence of certain conditions specified in the Indenture, and on or after February 15, 2019 until the close of business on the second
Scheduled Trading Day immediately preceding the Maturity Date regardless of the occurrence of such conditions, to convert any of its Securities or portion thereof that is $1,000 or an integral multiple thereof, into shares of Common Stock or,
following the Company’s receipt of Shareholder Approval, cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election, at the Conversion Rate specified in the Indenture, as adjusted from time
to time as provided in the Indenture. 
 All terms used in this Security but not specifically defined herein are defined in the Indenture
and are used herein as so defined. 
 In the case of any conflict between the provisions of this Security and the Indenture, the provisions
of the Indenture shall control. 
 This Security shall not be valid until an authorized signatory of the Trustee manually signs the
certificate of authentication on this Security. 
 THE INDENTURE AND THIS SECURITY, AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR
RELATED TO THE INDENTURE OR THIS SECURITY, SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 The
Company will furnish to any Holder, upon written request and without charge, a copy of the Indenture. Requests may be made to: Aegerion Pharmaceuticals, Inc., 101 Main Street, Suite 1850, Cambridge, MA 02142, Attention: Investor Relations.
