which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that
continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such
Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section
2.05(c) 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 Note as to which any of the conditions set forth in clause (i) through (iii) of the
immediately preceding sentence have been satisfied, and, upon such instruction, the Custodian 

  
 13 








 
shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the restrictive legend specified in this Section 2.05(c) 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 Notes or any Common Stock issued upon
conversion of the Notes has been declared effective under the Securities Act. 
 Notwithstanding any other provisions of this Indenture
(other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or
a participant in, the Depositary (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section
2.05(c). 
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust
Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as
custodian for Cede & Co. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable
to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed
within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the Company shall execute, and
the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal
amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a
portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled. 

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. Upon execution and authentication, the Trustee shall deliver such Physical
Notes to the Persons in whose names such Physical Notes are so registered. 
 At such time as all interests in a Global Note have been
converted, canceled, purchased, redeemed or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time
prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, purchased, redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or
transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the
case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 

Neither the Company, the Trustee nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

(d) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Note shall bear
a legend in substantially the following form (unless such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the 

  
 14 








 
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 a Note that has 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 

(2) AGREES FOR THE BENEFIT OF INSULET CORPORATION (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 (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that 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 (iii) that has been sold pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force under the Securities Act, 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 2.05(d). 

  
 15 








 (e) Any Note or Common Stock issued upon the conversion or exchange of a Note 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 immediately preceding) may not be resold by 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 Note or Common Stock, as the case may be, no longer being a “restricted security” (as
defined under Rule 144). The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.08. 

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen,
the Company in its discretion may execute, and upon receipt of a Company Order request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction,
loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the Holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been surrendered for required purchase or is about to be
converted in accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of
the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such
security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the
Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth
in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect
to the replacement or payment or conversion or purchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with
respect to the replacement or payment or conversion or purchase of negotiable instruments or other securities without their surrender. 

Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an
authenticating agent appointed by the Trustee shall, upon receipt of a Company Order, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form
of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee
or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating
agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the
Trustee or such authenticating agent, upon Company Order, shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the


  
 16 








 
Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations
under this Indenture as Physical Notes authenticated and delivered hereunder. 
 Section 2.08. Cancellation of Notes Paid,
Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, purchase, redemption, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee that the Company controls, to
be surrendered to the Trustee for cancellation, and, upon being so surrendered for cancellation, such Notes shall no longer be deemed outstanding for purposes of this Indenture. All Notes delivered to the Trustee shall be canceled promptly by it in
accordance with the terms of this Indenture, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall cancel such Notes in accordance with its customary
procedures and, after such cancellation, shall deliver a certificate of such cancellation to the Company, at the Company’s written request in a Company Order. If the Company or any of its Subsidiaries shall acquire any of the Notes, such
acquisition shall not operate as a redemption, purchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 

Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and,
if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such 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 Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 

Section 2.10. Additional Notes; Purchases. The Company may, without the consent of the Holders and notwithstanding Section 2.01,
reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue price and the interest accrued prior to the issue date of such additional Notes) in an
unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes will have one or more separate CUSIP
numbers. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such
matters, in addition to the due authorization, execution, delivery, validity and enforceability of such additional Notes and those required by Section 17.05, as the Trustee shall reasonably request. In addition, the Company may, to the extent
permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), purchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or
exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives (in each case, without prior notice to Holders). The Company shall cause any Notes so purchased (other than Notes purchased pursuant
to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08, and such Notes shall no longer be considered outstanding under this Indenture upon their purchase. 

ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officer’s
Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore authenticated and
delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid or converted as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d)) 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 Notes have become due and payable, whether at the Maturity Date, any Redemption Date, any Fundamental Change Purchase Date, upon conversion or otherwise, cash or 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 Notes and all other sums due and payable under this Indenture by the Company; and (b) the Company has
delivered to the Trustee an Officer’s 

  
 17 








 
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 7.06 shall survive. 

ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01. Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the principal
(including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. 

Section 4.02. Maintenance of Office or Agency. The Company will maintain in a State of the United States of America or the
District of Columbia, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or purchase (“Paying Agent”) or for conversion (“Conversion
Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office or the office or agency of the Trustee. 
 The Company may also from time to time designate as co-Note Registrars one
or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve
the Company of its obligation to maintain an office or agency in any State of the United States of America or the District of Columbia for such purposes. The Company will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar and Conversion Agent and the Corporate Trust Office
shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 
 Section 4.03. Appointments to
Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee
hereunder. 
 Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the
Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 

(i) that it will hold all sums held by it as such agent for the payment of the principal (including the Redemption Price and
the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes; 

(ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including
the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and 

(iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the
Trustee all sums so held in trust. 
 The Company shall, on or before each due date of the principal (including the Redemption Price and the
Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Redemption Price and the Fundamental Change


  
 18 








 
Purchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action;
provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date. 

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price and
the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the
Redemption Price and the Fundamental Change Purchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make
any payment of the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable. 

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction
and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be
held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such
sums or amounts. 
 (d) Any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including
the Redemption Price and the Fundamental Change Purchase Price, if applicable) or interest has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money
and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease. 
 Section 4.05.
Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 

Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not subject to
Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the meaning of Rule
144(a)(3) under the Securities Act, promptly provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issuable upon conversion of such Notes, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial owner of
such Notes or such Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A, as such rule may be amended from
time to time. 
 (b) The Company shall file with the Trustee, within 15 days after the same are required to be filed with the Commission
(giving effect to any grace period provided by Rule 12b-25 under the Exchange Act), copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (excluding any
such information, documents or reports, or portions thereof, subject to confidential treatment and any correspondence with the Commission). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system
shall be deemed to be filed with the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system; provided, however, that the Trustee shall have no obligation to determine whether or not such information,
documents or reports have been filed pursuant to the “EDGAR” system (or any successor thereto). 

  
 19 








 (c) Delivery of the reports and documents described in subsection (b) above to the Trustee is for
informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of
its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate). 
 (d) If, at any time
during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K) and the Company has not cured such failure to timely file within 14 days
after such failure, or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding
(as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per
annum of the principal amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is continuing or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other
than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding), ending on the date that is one year from the last date of original issuance of the Notes. As used in
this Section 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the
Commission pursuant to Section 13 or 15(d) of the Exchange Act. 
 (e) If, and for so long as, the restrictive legend on the Notes
specified in Section 2.05(c) has not been removed, the Notes are assigned a restricted CUSIP or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the
Company’s Affiliates at any time during the three months immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 365th day after the last date of original issuance of
the Notes, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the
Notes are assigned an unrestricted CUSIP and the Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately
preceding) (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes). 
 (f) Additional Interest
will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes. 
 (g) The
Additional Interest that is payable in accordance with Section 4.06(d) or Section 4.06(e) shall be separate and distinct from, and, subject to the immediately succeeding sentences, in addition to any Additional Interest that may accrue as
a result of the Company’s election pursuant to Section 6.03. However, in no event shall any Additional Interest that may accrue as a result of the Company’s failure to comply with its obligations pursuant to Section 4.06(d) or Section
4.06(e), together with any Additional Interest payable at the Company’s election pursuant to Section 6.03 as the remedy for an Event of Default relating to its failure to comply with its obligations as set forth in Section 4.06(b), accrue at a
rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. 

(h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or Section 4.06(e), the Company shall deliver to
the Trustee an Officer’s Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the
Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company
shall deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment. 

  
 20 








 Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent
that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying
all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it
may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted. 
 Section 4.08. Compliance Certificate; Statements
as to Defaults. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2016) an Officer’s Certificate stating whether or not the
signers thereof have knowledge of any failure by the Company to comply with all conditions and covenants then required to be performed under this Indenture and, if so, specifying each such failure and the nature thereof. 

In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within 30 days after the Company becomes aware of
the occurrence of any Event of Default or Default that is continuing, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company proposes to take with respect thereto. 

Section 4.09. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 

Section 4.10. Additional Amounts. 

(a) If the Company consolidates with or merges with or into, or sells, conveys, transfers or leases the Company’s consolidated properties
and assets substantially as an entirety to, another company pursuant to Section 11.01, 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 Notes, including, but not limited to, payments of principal (including, if applicable, the Redemption Price and the Fundamental Change Purchase
Price), payments of interest and deliveries of Common Stock or other Reference Property and/or payments of cash, in each case, upon conversion, shall be made without withholding or deduction for, or on account of, any present or future taxes,
duties, assessments or governmental charges of whatever nature imposed or levied by a taxing authority within any jurisdiction in which the 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 regulation or
governmental policy having the force of law. 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, duty, assessment or other governmental charge 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 Note and the Relevant
Taxing Jurisdiction, other than merely holding such Note 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; 

  
 21 








 (2) the presentation of such Note (in cases in which presentation is required)
more than 30 days after the later of the date on which the payment of the principal of (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) and interest on, such Note or the delivery of Common Stock and other
Reference Property and/or payments of cash, in each case, upon conversion of such Note 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
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, assessment or other governmental
charge; 
 (C) any tax, duty, assessment or other governmental charge that is payable otherwise than by withholding or
deduction from payments under or with respect to the Notes; 
 (D) any tax, assessment, withholding or deduction 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
implementing FATCA in any jurisdiction, 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 
 (E) any combination of taxes referred to in the preceding clauses (A), (B),
(C) and (D), or 
 (ii) with respect to any payment of the principal of (including the Redemption Price and the Fundamental
Change Purchase Price, if applicable) and interest on, such Note or the delivery of Common Stock or other Reference Property and/or payments of cash, in each case, upon conversion of such Note 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. 

(b) In the event that (i) the taxing authority of a Relevant Taxing Jurisdiction determines that amounts should have been withheld or
deducted in respect of any payments or deliveries under or with respect to the Notes in excess of any amounts that were actually withheld or deducted by the Successor Company, and (ii) the Successor Company would have been required to pay
Additional Amounts if such amounts had been withheld or deducted, then the Successor Company shall indemnify each beneficial owner of the Notes, on an after-tax basis, for any and all losses incurred as a result of its failure to make such
withholdings and deductions and to pay Additional Amounts; provided that (i) only direct losses (and no consequential losses or damages) shall be recoverable pursuant to 

  
 22 








 
this Section 4.10(b), (ii) no indemnification shall be required pursuant to this Section 4.10(b) unless and after such beneficial owner has exhausted all reasonable remedies available to it
to reduce or eliminate the amount of such losses, and (iii) as a condition of such indemnification such beneficial owner shall reasonably assist the Successor Company in any attempt the Successor Company may make to seek to secure a reduction
or refund of any such amounts, which reduction or refund shall be for the account of the Successor Company to the extent of any indemnification previously provided to such beneficial owner. 

(c) If the Successor Company is required to make any deduction or withholding from any payments with respect to the Notes, 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. 

(d) Any reference in this Indenture or the Notes 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 Note or the payment of principal of (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) and interest on, any Note or any other amount payable with respect to such Note,
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 4.10.

semi-annually, not more than 5 days after each March 1 and September 1 in each year beginning with March 1, 2017, and at such other times as the Trustee may request in writing, within 10 days after receipt by the Company of any such

current a form as is reasonably practicable, all information as to the names and addresses of the Holders contained in the most recent list furnished to it as provided in Section 5.01 or maintained by the Trustee in its capacity as Note Registrar,

 23 








 (e) failure by the Company to comply with its obligations under Article 11; 

(f) failure by the Company for 60 days after written notice from the Trustee or the Holders of at least 25% in principal amount of the Notes
then outstanding (a copy of which notice, if given by holders, also to be given to the Trustee) has been received by the Company to comply with any of its other agreements contained in the Notes or this Indenture; 

(g) default by the Company or any Significant Subsidiary of the Company in the payment of the principal or interest on any mortgage, agreement
or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any debt for money borrowed in excess of $40,000,000 (or its foreign currency equivalent) in the aggregate of the Company and/or any such
Significant Subsidiary, whether such debt now exists or shall hereafter be created, resulting in such debt becoming or being declared due and payable, and such acceleration shall not have been rescinded or annulled or such failure to pay shall not
have been cured, as the case may be, within thirty days after written notice to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Notes then outstanding; 

(h) a final judgment for the payment of $40,000,000 (or its foreign currency equivalent) or more (excluding any amounts covered by insurance
or indemnity) rendered against the Company or any Significant Subsidiary of the Company, which judgment is not discharged or stayed within 30 days after (i) the date on which the right to appeal thereof has expired if no such appeal has

 (i) the Company or any Significant Subsidiary
shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or

to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors; or 

(j) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation,
reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator,
custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive days. 

Section 6.02. Acceleration; Rescission and Annulment. In case one or more Events of Default shall have occurred and be continuing
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company (but not with respect to any of its Significant Subsidiaries)), unless the
principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by notice in writing
to the Company (and to the Trustee if given by Holders), may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall
automatically be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company (but not with
respect to any of its Significant Subsidiaries) occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable. 

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have
been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay
installments of accrued and unpaid interest upon all Notes and 

  
 24 








 
the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest, and on such principal at the
rate borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of
Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and
in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or
Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or
rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid interest on, any Notes, (ii) a failure to purchase any Notes when
required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 

Section 6.03. Additional Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the
Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall, for the first 360 days after the occurrence of such an Event of Default, consist
exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each day during the first 180 days after the occurrence of such Event of Default and
0.50% per annum of the principal amount of the Notes outstanding from the 181st day until the 360th day following the occurrence of such an Event of Default during which such Event of Default is continuing beginning on, and including,
the date on which such an Event of Default first occurs. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e), subject to
the immediately succeeding paragraph. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. On the 361st day after such Event of Default (if the Event of
Default relating to the Company’s failure to file is not cured or waived prior to such 361st day), the Notes will be subject to acceleration as provided in Section 6.02. The provisions of this paragraph will not affect the rights of Holders of
Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in Section 4.06(b). In the event the Company does not elect to pay Additional Interest following an
Event of Default in accordance with this Section 6.03, or the Company elects to make such payment but does not pay the Additional Interest when due, the Notes shall immediately be subject to acceleration as provided in Section 6.02. 

In no event shall Additional Interest payable at the Company’s election as the remedy for an Event of Default relating to the
Company’s failure to comply with its obligations under Section 4.06(b) as set forth in this Section 6.03, together with any Additional Interest that may accrue pursuant to Section 4.06(d) or Section 4.06(e), accrue at a rate in excess of
0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. 

In order to elect to pay Additional Interest as the sole remedy during the first 360 days after the occurrence of any Event of Default
described in the second immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent in writing of such election prior to the beginning of such 360-day period. Upon the failure to timely give
such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 
 Section 6.04. Payments of Notes
on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole
amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time and, in addition thereto, such further amount as shall be
sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for
the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the monies adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 

  
 25 








 In the event there shall be pending proceedings for the bankruptcy or for the reorganization of
the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have
been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the
creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and
unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on
the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under
Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the
event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including
any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings
shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such
proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 
 Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder 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. 
 All rights of action and of asserting claims under this
Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for
the ratable benefit of the Holders of the Notes. 
 In any proceedings brought by the Trustee (and in any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such
proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been
discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the
Company, the Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee
shall continue as though no such proceeding had been instituted. 

  
 26 








 Section 6.05. Application of Monies Collected by Trustee. Any monies collected by the
Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the payment of all amounts due the Trustee under
Section 7.06; 
 Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest
on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the
Trustee) upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto; 

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the
whole amount (including, if applicable, the payment of the Redemption Price, the Fundamental Change Purchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the
overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole
amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the payment of the Redemption Price, the Fundamental Change Purchase Price and any cash due upon conversion) and interest without preference
or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable,
the payment of the Redemption Price, the Fundamental Change Purchase Price and any cash due upon conversion) and accrued and unpaid interest; and 

Fourth, to the payment of the remainder, if any, to the Company. 

Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the
Redemption Price and the Fundamental Change Purchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any
provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any
other remedy hereunder, unless: 
 (a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of
the continuance thereof, as herein provided; 
 (b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding
shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 
 (c)
such Holders shall have offered to the Trustee such security or indemnity satisfactory to it against any loss, liability or expense to be incurred therein or thereby; 

(d) the Trustee for 60 days after its receipt of such notice, request and offer of such security or indemnity, shall have neglected or refused
to institute any such action, suit or proceeding; and 
 (e) no direction that, in the opinion of the Trustee, is inconsistent with such
written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.09, 

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that
no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all 

  
 27 








 
Holders, except as otherwise provided herein (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly
prejudicial to such Holders). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any Holder to receive payment or delivery,
as the case may be, of (x) the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such
Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the
Company shall not be impaired or affected without the consent of such Holder. 
 Section 6.07. Proceedings by Trustee. In case
of an Event of Default the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in
equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any
other legal or equitable right vested in the Trustee by this Indenture or by law. 
 Section 6.08. Remedies Cumulative and
Continuing. Except as provided in the last paragraph of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof
or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or
omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of
Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Holders. 
 Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of
Holders. The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and
(b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or
that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any
past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Redemption Price and any Fundamental Change Purchase Price) of, the
Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a
covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to
their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as
permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon. 
 Section 6.10. Notice of Defaults. The Trustee shall, within 90 days
after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, send to all Holders as the names and addresses of such Holders appear upon the Note Register, notice of all Defaults known to a Responsible
Officer, unless such 

  
 28 








 
Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Redemption Price
and the Fundamental Change Purchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such
notice if and so long as it in good faith determines that the withholding of such notice is in the interests of the Holders. 

Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Redemption Price and the Fundamental Change Purchase Price) on or after the due date expressed or provided

ARTICLE 7 

CONCERNING THE TRUSTEE 

Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the
curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred that has not been cured or waived the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such
Holders have offered to the Trustee indemnity or security satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct, except that: 
 (a) prior to the occurrence of an Event of Default and after the curing or
waiving of all Events of Default that may have occurred: 
 (i) the duties and obligations of the Trustee shall be determined
solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read
into this Indenture against the Trustee; and 
 (ii) in the absence of bad faith or willful misconduct on the part of the
Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture;
but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 

(b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless
it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 

  
 29 








 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it
in good faith in accordance with the direction of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined as provided in Section 8.04 relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 

(d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording
protection to, the Trustee shall be subject to the provisions of this Section 7.01; 
 (e) the Trustee shall not be liable in respect of any
payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to the Notes; 

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

(g) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest
bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or
the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any
amounts held hereunder in the absence of such timely and written investment direction from the Company; and 
 (h) in the event that the
Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent, transfer agent or other agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 7 shall also be
afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent, transfer agent or other agent hereunder. 

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 
 Section 7.02.
Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 7.01: 
 (a) the Trustee may conclusively rely and
shall be fully protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, Note, coupon or other paper or document believed by it in good faith to be genuine and to have been
signed or presented by the proper party or parties; 
 (b) any request, direction, order or demand of the Company mentioned herein shall be
sufficiently evidenced by an Officer’s Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an
Assistant Secretary of the Company; 
 (c) the Trustee may consult with counsel of its selection and require an Opinion of Counsel and any
advice of such counsel or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(d) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit,
and, if the Trustee shall determine to make such further 

  
 30 








 
inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the Company and shall incur no
liability of any kind by reason of such inquiry or investigation; 
 (e) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney appointed by
it with due care hereunder; 
 (f) the permissive rights of the Trustee enumerated herein shall not be construed as duties; 

(g) in no event shall the Trustee be liable for any consequential, indirect, punitive or special loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; 

(h) the Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a
Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee at its Corporate Trust Office by the Company or by any Holder of
the Notes; 
 (i) the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties
hereunder; and 
 (j) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of
officers authorized at such time to take specified actions pursuant to this Indenture. 
 Section 7.03. No Responsibility for
Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated
and delivered by the Trustee in conformity with the provisions of this Indenture. 
 Section 7.04. Trustee, Paying Agents,
Conversion Agent, Bid Solicitation Agent or Note Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent, Bid Solicitation Agent (if other than the Company or any Affiliate thereof) or Note Registrar, in its individual or
any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying Agent, Conversion Agent, Bid Solicitation Agent or Note Registrar. 

Section 7.05. Monies and Shares of Common Stock to Be Held in Trust. All monies and shares of Common Stock received by the Trustee
shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money and shares of Common Stock held by the Trustee in trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any money or shares of Common Stock received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee. 

Section 7.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and
the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to
in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the
provisions of this Indenture in any capacity thereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or
advance as shall have been caused by its negligence or willful misconduct. The Company also covenants to indemnify the Trustee in 

  
 31 








 
any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any
loss, claim, damage, liability or expense incurred without negligence or willful misconduct on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in
connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability (whether asserted by the Company, a Holder or any other
Person) in the premises. The obligations of the Company under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim to which the Notes
are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to
receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company (even though the Notes may be so subordinated). The obligation of the Company under this Section 7.06 shall
survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The
indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee. 
 Without
prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 6.01(i) or Section 6.01(j)
occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. 

Section 7.07. Officer’s Certificate as Evidence. Except as otherwise provided in Section 7.01, whenever in the administration
of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the Trustee, and such Officer’s
Certificate, in the absence of negligence or willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 

Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible
pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of any supervising or examining authority, then for the purposes of this Section 7.08, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article 7. 

Section 7.09. Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such
resignation to the Company and by mailing notice thereof to the Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written
instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment within 60 days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, at the expense of the Company, upon 10 Business Days’ notice to the Company and the Holders, petition any court of
competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11, on behalf of himself and all others similarly
situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

  
 32 








 (b) In case at any time any of the following shall occur: 

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign after
written request therefor by the Company or by any such Holder, or 
 (ii) the Trustee shall become incapable of acting, or
shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, 
 then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by written
instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.11, any Holder who has
been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with Section
8.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within 10 days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee
so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may, at the expense of the Company, petition any court of competent jurisdiction for an appointment of a successor trustee. 

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 7.09
shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 
 Section 7.10.
Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon
the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the
provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate
on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06. 

No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee
shall be eligible under the provisions of Section 7.08. 
 Upon acceptance of appointment by a successor trustee as provided in this Section
7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Holders at their addresses as they shall
appear on the Note Register. If the Company fails to mail such notice within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 

Section 7.11. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate
trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided
that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of Section 7.08. 

  
 33 








 In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and
deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the
name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee
shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by
merger, conversion or consolidation. 
 ARTICLE 8 

CONCERNING THE HOLDERS 

Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the
aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with such rules as may be established in accordance with Section 17.17, or (c) by a combination of such instrument or instruments and any such
record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the
record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 

Section 8.02. Proof of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and such rules as may be
established in accordance with Section 17.17, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in
such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided by the Trustee
in accordance with Section 17.17. 
 Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating
agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be
overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03)
accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the
contrary. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability
for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any Holder of a beneficial interest in a Global Note may directly enforce against the
Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the
provisions of this Indenture. 
 Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this 

  
 34 








 
Indenture, Notes that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company shall be
disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action
only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the
satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the
Company. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an
Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such
Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. The Trustee shall not be required at any time to request a
list of Company-owned Notes before taking any actions or making any calculations. 
 Section 8.05. Revocation of Consents; Future
Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this
Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office
and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders
and owners of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or
substitution therefor or upon registration of transfer thereof.

 Upon the written request of the Company, the Trustee is hereby
authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion,
enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section 10.01 may be executed by the Company and the Trustee without the

Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8) of the
Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a purchase of, or tender offer or

the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that,

(g) change the ranking of the Notes;

consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

Holders do not need under this Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be sufficient if
such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall deliver to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all
the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 
 Section 10.03.
Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective
rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and
amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

Section 10.04. Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to
the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so
modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company,
authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.10) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 

Section 10.05. Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by
Section 17.05, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 10 and is permitted or
authorized by this Indenture, and is the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms. 

ARTICLE 11 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 11.01. Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 11.02, the Company shall not
consolidate with, merge with or into, or sell, convey, transfer or lease its consolidated properties and assets substantially as an entirety to another Person, unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be (1) a
corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia or (2) a corporation or entity treated as a corporation for U.S. federal income tax purposes organized and existing
under the laws of Switzerland, the Republic of Ireland or the United Kingdom, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the
Trustee, all of the obligations of the Company under the Notes and this Indenture (including, for the avoidance of doubt, the obligation to pay Additional Amounts, as set forth in Section 4.10); and 

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this
Indenture. 

  
 37 








 For purposes of this Section 11.01, the sale, conveyance, transfer or lease of the properties and
assets of one or more Subsidiaries of the Company substantially as an entirety to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute the properties and assets of the Company
substantially as an entirety on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of the properties and assets of the Company substantially as an entirety to another Person. 

Section 11.02. Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or
lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on
all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by
the Company, such Successor Company (if not the Company) shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part, except in the case of a lease of the Company’s
properties and assets substantially as an entirety. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not
have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate
and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter
shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article
11 the Person named as the “Company” in the first paragraph of this Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated at any time
thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes. 

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance)
may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 11.03. Opinion of Counsel to Be Given to
Trustee. No consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale,
conveyance, transfer or lease and any such assumption complies with the provisions of this Article 11 and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this
Article 11 and Article 10 and has been duly authorized, executed and delivered by the Successor Company, and is the legal, valid and binding obligation of the Successor Company, enforceable against the Successor Company in accordance with its terms.

 ARTICLE 12 

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND
DIRECTORS 
 Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the
principal of or accrued and unpaid interest on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental
indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of the Company
or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

INTENTIONALLY OMITTED 

ARTICLE 14 

CONVERSION OF NOTES 

Section 14.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 14, each Holder of a
Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or a multiple thereof) of such Note (i) subject to satisfaction of the conditions described in
Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding June 15, 2021 under the circumstances and during the periods set forth in Section 14.01(b), and (ii) irrespective of the conditions
described in Section 14.01(b), on or after June 15, 2021 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 17.1332 shares of Common
Stock (as adjusted as provided in Section 14.04 as of any date, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 14.02, the “Conversion Obligation”). 

(b) (i) Prior to the close of business on the Business Day immediately preceding June 15, 2021 the Notes may be surrendered for
conversion during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request
by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading Day. The
Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other
than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent (if other than
the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination in writing, and the Company shall have no obligation to make such request (or, if the
Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000
principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) in writing
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 Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per
Note is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation
Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such
determination, or (y) the Company is acting as Bid Solicitation Agent and the Company fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of
Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall
so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal
to 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing. 

(ii) If, prior to the close of business on the Business Day immediately preceding June 15, 2021, the Company elects to:

 (A) distribute to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for
a period of not more than 60 calendar days from the 

  
 39 








 
declaration date of such distribution, to subscribe for or purchase shares of its Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for
the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution; or 

(B) distribute to all or substantially all holders of its Common Stock the Company’s assets, debt securities or rights to
purchase securities of the Company, which distribution has a per share value, as determined by the Board of Directors, exceeding 10% of the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending
on, and including, the Trading Day immediately preceding the declaration date for such distribution, 
 then, in either case, the Company shall notify all
Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing at least 35 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution. Once the Company has given such notice, the Notes may be
surrendered for conversion at any time until the earlier of (1) the close of business on the Business Day immediately prior to the Ex-Dividend Date for such distribution or (2) the Company’s announcement that such distribution will
not take place, even if the Notes are not otherwise convertible at such time. 
 (iii) If a transaction or event that
constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding June 15, 2021, regardless of whether a Holder has the right to require the Company to purchase
the Notes pursuant to Section 15.02, the Notes may be surrendered for conversion at any time from and after the 35th Business Day prior to the anticipated effective date of such Fundamental Change or Make-Whole Fundamental Change, as the case may be
(or, if later, the Business Day after the date on which the Company gives notice pursuant to the immediately succeeding sentence), until the Business Day immediately preceding the Fundamental Change Purchase Date corresponding to such Fundamental
Change (or, in the case of a Make-Whole Fundamental Change that does not constitute a Fundamental Change by virtue of the proviso in clause (b) of the definition of Fundamental Change, the 35th Trading Day immediately following such
effective date). The Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing of the anticipated effective date of any Fundamental Change or Make-Whole Fundamental Change, as the case
may be, as soon as practicable after the Company first determines the anticipated effective date of such Fundamental Change or such Make-Whole Fundamental Change, as the case may be; provided that the Company shall not be required to give
such notice more than 35 Scheduled Trading Days in advance of such anticipated effective date. 
 (iv) Prior to the close of
business on the Business Day immediately preceding June 15, 2021, the Notes may be surrendered for conversion during any calendar quarter commencing after the calendar quarter ending on December 31, 2016 (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, and including, the last Trading Day of the immediately preceding
calendar quarter is equal to or greater than 130% of the Conversion Price then in effect on each applicable Trading Day as determined by the Company. 

(v) If the Company calls any or all of the Notes for redemption pursuant to Article 16 prior to the close of business on the
Business Day immediately preceding June 15, 2021, then Holders may surrender for conversion Notes that have been so called for redemption at any time prior to the close of business on the Business Day prior to the Redemption Date, even if the
Notes are not otherwise convertible at such time. After that time, the right to convert such Notes shall expire, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert its Notes until the
Redemption Price has been paid or duly provided for. 
 Section 14.02. Conversion Procedure; Settlement Upon Conversion. 

 (a) Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall pay or deliver,
as the case may be, to the converting Holder, in respect of each $1,000 principal 

  
 40 








 
amount of Notes 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 (j) of this Section 14.02 (“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 (j) of this Section 14.02 (“Combination Settlement”), at its election, as set forth in this Section 14.02. 

(i) All conversions occurring on or after June 15, 2021, and all conversions occurring after the Company’s issuance
of a Redemption Notice with respect to the Notes and prior to the related Redemption Date, shall be settled using the same Settlement Method. 

(ii) Prior to June 15, 2021, except for any conversions that occur after the Company’s issuance of a Redemption
Notice with respect to the Notes but prior to the related Redemption Date, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same
Settlement Method with respect to conversions that occur on different Conversion Dates. 
 (iii) If, in respect of any
Conversion Date (or one of the periods described in the third immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in
respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to converting 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 occurring (x) after the date of issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date, in such Redemption Notice or (y) on or after
June 15, 2021, no later than June 15, 2021). If the Company 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 Notes shall be equal to $1,000. Such Settlement Notice
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 delivers a Settlement Notice electing Combination
Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount in such Settlement Notice, the Specified Dollar Amount shall be deemed to be $1,000. 

(iv) The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes
(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 a number of shares of Common Stock equal to the product of (1) the aggregate principal amount of Notes to be
converted, divided by $1,000, and (2) the Conversion Rate in effect on the Conversion Date; 
 (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 Notes being converted cash in an amount equal to the
sum of the Daily Conversion Values for each of the 25 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 Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 25 consecutive
Trading Days during the related Observation Period. 
 (v) 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. 

  
 41 








 
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 delivering any fractional share of
Common Stock, 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 delivering
fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 

(b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall
(i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in
Section 14.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of
Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares
of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office
of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth
in Section 14.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be
surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Purchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Purchase Notice in accordance with Section 15.03. 

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

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 14.03(b) and Section 14.07(a), 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, if the Company elects Physical Settlement, 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 Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to
or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, 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 Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue
of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to
deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately
preceding sentence. 

  
 42 








 (f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares
of Common Stock issued upon the conversion of any Note as provided in this Article 14. 
 (g) Upon the conversion of an interest in a Global
Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of
Notes effected through any Conversion Agent other than the Trustee. 
 (h) Upon conversion, a Holder shall not receive any separate cash
payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid
interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a
conversion of Notes into a combination of cash and shares of Common Stock accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of
business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the
conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of
interest payable on the Notes so converted; provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption
Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date (or, if such Interest Payment Date is not a Business Day, the Business Day immediately following such Interest Payment Date); (3) if the Company
has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date (or, if such Interest Payment Date is not a Business Day, the Business Day immediately following such
Interest Payment Date); or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exist at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date
immediately preceding the Maturity Date, Redemption Date as described in clause (2) of the immediately preceding sentence or Fundamental Change Purchase Date as described in clause (3) in the immediately preceding sentence shall receive
the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been converted following such Regular Record Date. 

(i) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a
stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company
elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion. 

(j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of
delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation
Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has 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. 

Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental
Changes. (a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate
for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for these purposes to be “in connection
with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the 

  
 43 








 
Make-Whole Fundamental Change up to, and including, the Business Day immediately preceding the related Fundamental Change Purchase Date (or, in the case of a Make-Whole Fundamental Change that
would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole
Fundamental Change Period”). 
 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change
pursuant to Section 14.01(b)(iii), the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.02; provided, however, that
if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property is composed entirely of cash, for any conversion of Notes 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 of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate
(including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date. 

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased for conversions during the Make-Whole Fundamental
Change Period shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs (the “Effective Date”) and the price (the “Stock Price”) paid or deemed paid per
share of the Common Stock in the Make-Whole Fundamental Change. If holders of the Common Stock receive only cash in the case of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price
shall be the cash amount paid per share. In the case of any other Make-Whole Fundamental Change, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the
Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, 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, effective date (as defined for purposes of Section 14.04) or Expiration Date of the event occurs, during such five consecutive
Trading Day period. 
 (d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which
the Conversion Rate of the Notes is otherwise adjusted. 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 such 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 set forth in the table below shall be adjusted in the same manner and
at the same time as the Conversion Rate as set forth in Section 14.04. 
 (e) The following table sets forth the number of Additional Shares
by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date set forth below:

 The exact Stock Prices and Effective Dates 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 above or the Effective Date is between two Effective Dates in
the table, the number of Additional Shares shall be determined by a 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 greater than $160.00 per share (subject to adjustment in the same manner as
the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii) if the Stock Price is less than $44.05 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding
the foregoing, in no event shall the Conversion Rate exceed 22.7014 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 

(f) As soon as practicable after the Company determines the anticipated Effective Date of any proposed Make-Whole Fundamental Change the
Company shall deliver to each Holder, the Trustee and the Conversion Agent written notice of, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the
Company’s website, the anticipated Effective Date of such proposed Make-Whole Fundamental Change; provided that the Company shall not be required to give such written notice or issue such press release more than 35 Scheduled Trading Days
in advance of such anticipated Effective Date. No later than five Business Days after the actual Effective Date of each Make-Whole Fundamental Change, the Company shall deliver to each Holder, the Trustee and the Conversion Agent written notice of,
and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the Company’s website, such Effective Date. 

(g) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04 in respect of a Make-Whole
Fundamental Change. 
 Section 14.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by
the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (as a result of holding the Notes and contemporaneously with holders of the Common
Stock) in any of the transactions described in this Section 14.04 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 Notes held by such Holder,
without having to convert their Notes. 
 (a) If the Company issues solely shares of Common Stock as a dividend or distribution on all or
substantially all of the shares of Common Stock, or if the Company effects a share split or share combination of the Common Stock, the applicable Conversion Rate will be adjusted based on the following formula: 

 

					
	CR’ = CR0 ×	 	  OS’  	  	
	 	OS0	  	

  

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


  
 45 








 Any adjustment made under this Section 14.04(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
14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared. 
 (b) If the Company distributes to all or substantially all holders of its
Common Stock any rights, options or warrants entitling them for a period of not more than 60 calendar days from the declaration date of such distribution to subscribe for or purchase shares of the Common Stock, at a price per share less than the
average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution, the Conversion Rate shall be increased
based on the following formula: 
  

									
	CR’ = CR0 	 	×	 	 OS0 + X
	  	 
	 	 	OS0 + Y	  	

  

							
	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 the Ex-Dividend Date for such distribution;
				
		 	OS0	  	=	  	the number of shares of the Common Stock that are outstanding immediately prior to the open of business on the Ex-Dividend Date for such distribution;
				
		 	X	  	=	  	the total number of shares of the Common Stock issuable pursuant to such rights, options or warrants; and
				
		 	Y	  	=	  	the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date relating to such distribution of such rights, options or warrants.

 Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants are
distributed and shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants,
the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the distribution 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 distributed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such distribution had not occurred.


  
 46 








 For purposes of this Section 14.04(b) and for the purpose of Section 14.01(b)(ii)(A), 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 10 consecutive Trading Day period
ending on, and including, the Trading Day immediately preceding the declaration date of such distribution, 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 its other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends or distributions (including share splits) as to which an adjustment was effected pursuant to Section
14.04(a)or Section 14.04(b), (ii) dividends or distributions paid in cash as to which an adjustment was effected pursuant to Section 14.04(d), and (iii) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall
apply (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: 
  

									
	CR’ = CR0	 	 ×
	 	 SP0
	  	 
	 	 	SP0 - FMV	  	

  

							
	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 the Ex-Dividend Date for such distribution;
				
		 	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 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 distributed with respect to each outstanding share of the Common Stock as of the open of business on the Ex-Dividend Date for such
distribution.

 Any increase made under the portion of this Section 14.04(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 Note
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 Stock receive the Distributed Property, the amount and kind 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 14.04(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 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution. 

  
 47 








 With respect to an adjustment pursuant to this Section 14.04(c) where there has been a dividend
or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, which Capital Stock or similar equity interest will be
quoted or listed for trading on a U.S. national securities exchange or other established automated over-the-counter trading market in the United States after its distribution (a “Spin-Off”), the Conversion Rate in effect immediately
before the close of business on the tenth Trading Day immediately following, and including, the Ex-Dividend Date for the Spin-Off will be increased based on the following formula: 

 

					
	CR’ = CR0 ×	 	 FMV + MP0
	 	
	 	MP0	 	

  

							
	where	  		  		  	
				
		  	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the tenth Trading Day immediately following, and including, the Ex-Dividend Date for the Spin-Off;
				
		  	CR’	  	=	  	the Conversion Rate in effect immediately after the close of business on the tenth Trading Day immediately following, and including, the Ex-Dividend Date for the Spin-Off;
				
		  	FMV	  	=	  	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 the Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period immediately following, and including, the Ex-Dividend Date for the Spin-Off;
and
				
		  	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the first 10 consecutive Trading Day period immediately following and including the Ex-Dividend Date for the Spin-Off.

 The adjustment to the Conversion Rate under the preceding paragraph shall become effective at the close of
business on the tenth Trading Day immediately following, and including, the Ex-Dividend Date for the Spin-Off; provided that, for purposes of determining the Conversion Rate, (x) in respect of any conversion of Notes for which Physical
Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Ex-Dividend Date for any Spin-Off, references in the portion of this Section 14.04(c) related to Spin-Offs to 10
Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and the relevant Conversion Date and (y) in respect of any conversion of Notes for which Cash
Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Ex-Dividend Date for any Spin-Off,
references in the portion of this Section 14.04(c) related to Spin-Offs to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and such Trading Day in
determining the Conversion Rate as of such Trading Day. 
 For purposes of this Section 14.04(c) (and subject in all respect to Section
14.11), rights, options or warrants distributed by the Company to 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 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(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
14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become
exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights,
options or warrants with such rights (in which case the existing rights, 

  
 48 








 
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 14.04(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
14.04(a), Section 14.04(b) and this Section 14.04(c), any dividend or distribution to which this Section 14.04(c) is applicable that also includes one or both of: 

(A) a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the “Clause A
Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable (the
“Clause B Distribution”), 
 (1) other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or
distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 14.04(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 14.04(a) and Section 14.04(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 the Ex-Dividend Date for such dividend or distribution, or immediately prior to the
open of business on the effective date of such share split or share combination, as the case may be” within the meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on the Ex-Dividend Date for such
distribution” within the meaning of Section 14.04(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 increased based on the following formula: 
  

					
	CR’ = CR0 ×	 	 SP0
	 	
	 	SP0 - C	 	

  

					
	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 average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
and
			
	C	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.


  
 49 








 Any increase pursuant to this Section 14.04(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 Note shall receive, for each $1,000 principal amount of Notes, 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 offer or exchange offer for the Common Stock and the cash
and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading-Day period commencing on, and including, the Trading
Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be increased based on the following formula: 

 

					
	 CR’ = CR0 ×
	 	 FMV + (SP’ × OS’)
	  	
	 	(OS0 × SP’)	  	

  

							
	where	 		  		  	
				
		 	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the last Trading Day of the period of 10 consecutive Trading Days commencing on, and including, the Trading Day next succeeding the Expiration
Date;
				
		 	CR’	  	=	  	the Conversion Rate in effect immediately prior to the open of business on first day following the last Trading Day of the period of 10 consecutive Trading Days commencing on, and including, the Trading Day next succeeding the
Expiration Date;
				
		 	FMV	  	=	  	the fair market value (as determined by the Board of Directors), on the Expiration Date, of the aggregate value of all cash and any other consideration paid or payable for shares validly tendered or exchanged as of the Expiration
Date;
				
		 	OS’	  	=	  	the number of shares of Common Stock outstanding immediately after the time (the “Expiration Time”) tender or exchange offer expires (after giving effect to such tender offer or exchange offer);
				
		 	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Expiration Time (prior to giving effect to such tender offer or exchange offer); and
				
		 	SP’	  	=	  	the average of the Last Reported Sale Prices of 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 14.04(e) shall occur at the close of business on the
10th Trading Day immediately following the Expiration Date; provided that, for purposes of determining the Conversion Rate, (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion
Date occurs during the 10 Trading Days following, and including, the Trading Day next succeeding the Expiration Date, references in this Section 14.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading
Days as have elapsed between the Trading Day next succeeding the 

  
 50 








 
date that such tender or exchange offer expires and such Conversion Date and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for
any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days following, and including, the Trading Day next succeeding the Expiration Date, references in this Section 14.04(e) with respect to
10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Trading Day next succeeding the date such tender or exchange offer expires and such Trading Day in determining the Conversion Rate as of
such Trading Day. If the Company is obligated to purchase shares pursuant to any such tender offer or exchange offer, but the Company is permanently prevented by applicable law from effecting any or all or any portion of such purchases or all such
purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that have been
effected. 
 (f) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment
becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes 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 shares of Common Stock as of the related
Conversion Date as described under Section 14.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, 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. 

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent permitted by
applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days
if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s
securities are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of
shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address
appearing on the Note Register 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 Article 14, 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 the Company’s Subsidiaries; 

(iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable
or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued; 

  
 51 








 (iv) upon the repurchase of shares of Common Stock pursuant to an open-market
share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the kind described in Section 14.04(e); 

(v) solely for a change in the par value of the Common Stock; or 

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

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten
thousandth (1/10,000th) of a share. 
 (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file
with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a
Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which
it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes
effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of this Indenture. Failure to deliver such notice shall not affect the legality or validity of any such
adjustment. 
 (l) For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares
of Common Stock 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 of Common Stock issuable in respect
of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 Section 14.05. 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, effective date or Expiration Date of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the
Daily Settlement Amounts are to be calculated. 
 Section 14.06. Shares to Be Fully Paid. The Company shall provide, free from
preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming that at the time
of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement is applicable). 

Section 14.07. 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 

  
 52 








 (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 Notes shall be changed into a right to convert
such principal amount of Notes 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(h) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event (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 Notes in accordance with Section 14.02 and (B) (I) any amount payable in cash upon conversion
of the Notes in accordance with Section 14.02 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 Notes in accordance with Section 14.02 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 (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts
of consideration received by the holders of Common Stock that affirmatively make such an election or (y) 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, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders receive only
cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the
Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.03), 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. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing of such
weighted average as soon as practicable after such determination is made. 
 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 14. If, in the case of any Merger Event, the Reference Property includes shares of stock or other
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 Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the
purchase rights set forth in Article 15. 
 (b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a)
of this Section 14.07, the Company shall promptly file with the Trustee an Officer’s 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 deliver 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 Note Register 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. 

  
 53 








 (c) The Company shall not become a party to any Merger Event unless its terms are consistent with
this Section 14.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 14.01
and Section 14.02 prior to the effective date of such Merger Event. 
 (d) The above provisions of this Section shall similarly apply to
successive Merger Events. 
 Section 14.08. Certain Covenants. (a) The Company covenants that all shares of Common Stock
issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require
registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission,
secure such registration or approval, as the case may be. 
 (c) The Company further covenants that if at any time the Common Stock shall be
listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion
of the Notes. 
 Section 14.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be
under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or
extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be
accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any
other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or
other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the
foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or
amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the
provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be
obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 14.01(b)
has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 14.01(b) with respect to the commencement or
termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such
event or at such other times as shall be provided for in Section 14.01(b). 
 Section 14.10. Notice to Holders Prior to Certain
Actions. In case of any: 
 (a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate
pursuant to Section 14.04 or Section 14.11; 
 (b) Merger Event; or 

  
 54 








 (c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its
Subsidiaries; 
 then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall
cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to the applicable
date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common
Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or winding-up is expected to become effective or occur, and
the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give
such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up. 

Section 14.11. Stockholder Rights Plans. To the extent that the Company has a rights plan in effect upon conversion of the Notes,
each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in
each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. If at or prior to the time of conversion, however, the rights have separated from the shares of Common Stock in accordance
with the provisions of the applicable stockholder rights 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 Notes, the Conversion Rate shall be adjusted at the
time of separation as if the Company distributed to all or substantially all holders of Common Stock Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such
rights. 
 Section 14.12. Exchange In Lieu Of Conversion. (a) When a Holder surrenders its Notes for conversion, the
Company may, at its election, direct the Conversion Agent to surrender, on or prior to the second Business Day following the relevant Conversion Date, such Notes to a financial institution designated by the Company (the “Designated
Institution”) for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion for exchange in lieu of conversion, the Designated Institution must agree to timely deliver, in exchange for such Notes, the cash,
shares of Common Stock or combination of cash and shares of Common Stock, at the Company’s election, that would otherwise be due upon conversion as described in Section 14.02 above and in respect of which the Company has notified converting
Holders. If the Company makes the election described above, the Company shall, by the close of business on the second Business Day following the relevant Conversion Date, notify the Holder surrendering Notes for conversion that it has made such
election. In addition, the Company shall concurrently notify the Designated Institution of the relevant deadline for delivery of the consideration due upon conversion. Any Notes exchanged by the Designated Institution will remain outstanding. 

(b) If the Designated Institution agrees to accept any Notes for exchange but does not timely deliver the related consideration due upon
conversion to the Conversion Agent, or if the Designated Institution does not accept such Notes for exchange, the Company shall, within the time period specified in Section 14.02(c), convert such Notes into cash, shares of Common Stock or
combination of cash and shares of Common Stock, at the Company’s election, in accordance with the provisions of Section 14.02. 
 (c)
For the avoidance of doubt, in no event will the Company’s designation of a Designated Institution pursuant to this Section 14.12 require the Designated Institution to accept any Notes for exchange.

 ARTICLE 15 

PURCHASE OF NOTES AT OPTION OF HOLDERS

 Section 15.01. Intentionally Omitted. 

Section 15.02. Purchase at Option of Holders Upon a Fundamental Change. (a) If there shall occur a Fundamental Change at any
time prior to the Maturity Date, then each Holder shall have the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Notes, or any portion thereof that is a multiple of $1,000 principal amount,
on the date (the “Fundamental Change Purchase Date”) specified by the Company that is not less than 20 and not more than 35 Business Days after the date of the Fundamental Change Company Notice (as defined below) at a purchase price
equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, thereon to, but excluding, the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”), unless the Fundamental
Change Purchase Date is after a Regular Record Date and on or prior to the immediately succeeding Interest Payment Date, in which case interest accrued to the Interest Payment Date will be paid to Holders of the Notes as of the immediately preceding
Regular Record Date and the Fundamental Change Purchase Price payable to the Holder surrendering the Note for purchase pursuant to this Section 15.02 shall be equal to the principal amount of Notes subject to purchase. 

(b) Purchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon: 

(i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Purchase
Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the
Notes are Global Notes, in each case prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental
Change Purchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the
Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor. 
 The
Fundamental Change Purchase Notice in respect of any Notes to be purchased shall state: 
 (i) in the case of Physical Notes,
the certificate numbers of the Notes to be delivered for purchase; 
 (ii) the portion of the principal amount of Notes to be
purchased, which must be $1,000 or a multiple thereof; and 
 (iii) that the Notes are to be purchased by the Company
pursuant to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the
Fundamental Change Purchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of
business on the Business Day immediately preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03. 

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of
withdrawal thereof. 

  
 56 








 (c) On or before the 20th calendar day after the occurrence of the effective date of a
Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a written notice (the “Fundamental Change Company Notice”) of the
occurrence of the effective date of the Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be by first class mail or, in the case of Global Notes, in accordance with the
applicable procedures of the Depositary. Contemporaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City
of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time or issue a press release containing the relevant information. Each Fundamental Change Company Notice shall
specify: 
 (i) the events causing the Fundamental Change; 

(ii) the date the Fundamental Change occurred, and whether such Fundamental Change is a Make-Whole Fundamental Change, in which
case the Effective Date of such Make-Whole Fundamental Change shall also be specified; 
 (iii) the last date on which a
Holder may exercise the purchase right pursuant to this Article 15; 
 (iv) the Fundamental Change Purchase Price; 

(v) the Fundamental Change Purchase Date; 

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 

(vii) if applicable, the Conversion Rate and any adjustments to the Conversion Rate made or to be made on account of such
Fundamental Change; 
 (viii) if applicable, that the Notes with respect to which a Fundamental Change Purchase Notice has
been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with the terms of this Indenture; and 

(ix) the procedures that Holders must follow to require the Company to purchase their Notes. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ purchase rights or affect the
validity of the proceedings for the purchase of the Notes pursuant to this Section 15.02. 
 At the Company’s expense and written
request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

(d) Notwithstanding the foregoing, no Notes may be purchased by the Company on any date at the option of the Holders upon a Fundamental Change
if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change
Purchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by
the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes 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 Purchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 15.03. Withdrawal of Fundamental Change Purchase Notice. (a) A Fundamental Change Purchase Notice may be withdrawn
(in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 15.03 at any time prior to the close of business on the Business Day immediately preceding
the Fundamental Change Purchase Date, specifying: 
 (i) the principal amount of the Notes with respect to which such notice
of withdrawal is being submitted, which amount must be $1,000 or a multiple thereof, 

  
 57 








 (ii) if Physical Notes have been issued, the certificate number of the Note in
respect of which such notice of withdrawal is being submitted, and 
 (iii) the principal amount, if any, of such Note that
remains subject to the original Fundamental Change Purchase Notice, which portion must be in principal amounts of $1,000 or a multiple of $1,000; 

provided, however, that if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary. 

Section 15.04. Deposit of Fundamental Change Purchase Price. (a) The Company will deposit with the Trustee (or other Paying
Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Purchase Date an amount
of money sufficient to purchase all of the Notes to be purchased at the appropriate Fundamental Change Purchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes
surrendered for purchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date) will be made on the later of (i) the Fundamental Change Purchase Date with respect to
such Note (provided the Holder has satisfied the conditions in Section 15.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in
the manner required by Section 15.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by
wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change
Purchase Price. 
 (b) If by 11:00 a.m. New York City time, on the Fundamental Change Purchase Date, the Trustee (or other Paying Agent
appointed by the Company) holds money or securities sufficient to make payment on all the Notes or portions thereof that are to be purchased on such Fundamental Change Purchase Date, then (i) such Notes will cease to be outstanding,
(ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will
terminate (other than the right to receive the Fundamental Change Purchase Price, and subject to Section 15.02(a), previously accrued and unpaid interest upon delivery or transfer of such Notes). 

(c) Upon surrender of a Note that is to be purchased in part pursuant to Section 15.02, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unpurchased portion of the Note surrendered. 

Section 15.05. Covenant to Comply with Applicable Laws Upon Purchase of Notes. In connection with any purchase offer, the Company
will, to the extent required: 
 (a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the
Exchange Act that may then be applicable; 
 (b) file a Schedule TO or any successor or similar schedule required under the Exchange Act;
and 
 (c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to purchase the Notes;

 in each case, so as to permit the rights and obligations under this Article 15 to be exercised in the time and in the manner specified in this Article
15.

 ARTICLE 16 

OPTIONAL REDEMPTION 

Section 16.01. Optional Redemption. No sinking fund is provided for the Notes. The Notes shall not be redeemable by the Company
prior to September 15, 2019. On or after September 15, 2019 and prior to the Maturity Date, if the Last Reported Sale Price of the Common Stock has been at least 130% of the Conversion Price then in effect for at least 20 Trading Days
(whether or not consecutive) during any 30 consecutive Trading Day period ending within five Trading Days prior to the date on which the Company provides notice of redemption as set forth in Section 16.02, the Company may redeem (an
“Optional Redemption”) for cash all or part of the Notes, upon notice as set forth in Section 16.02, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any,
to, but excluding, the Redemption Date (the “Redemption Price”) (unless the Redemption Date falls after a Regular Record Date but on or prior to the immediately succeeding Interest Payment Date, in which case interest accrued to the
Interest Payment Date will be paid to Holders of record of such Notes on such Regular Record Date, and the Redemption Price will be equal to 100% of the principal amount of the Notes to be redeemed). 

Section 16.02. Notice of Optional Redemption; Selection of Notes.  

(a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may be, any part of the Notes pursuant to Section
16.01, it shall fix a date for redemption (each, a “Redemption Date”) and it or, at its written request received by the Trustee not less than 50 calendar days prior to the Redemption Date (or such shorter period of time as may be
acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall mail or cause to be mailed a notice of such Optional Redemption (a “Redemption Notice”) not less than 40 nor more than 60 calendar days
prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole or in part at its last address as the same appears on the Note Register; provided, however, that if the Company shall give such notice, it shall also
give written notice of the Redemption Date to the Trustee. 
 (b) The Redemption Notice, if mailed in the manner herein provided, shall be
conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail or any defect in the Redemption Notice to the Holder of any Note designated for redemption as
a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. 
 (c) Each Redemption Notice
shall specify: 
 (i) the Redemption Date (which must be a Business Day); 

(ii) the Redemption Price; 

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that
interest thereon, if any, shall cease to accrue on and after said date; 
 (iv) the place or places where such Notes are to
be surrendered for payment of the Redemption Price; 
 (v) that Holders may surrender their Notes for conversion at any time
prior to the close of business on the Business Day immediately preceding the Redemption Date; 
 (vi) the procedures a
converting Holder must follow to convert its Notes and the Settlement Method and Specified Cash Amount, if applicable; 

(vii) the Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with
Section 14.03; 
 (viii) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes; and 

  
 59 








 (ix) in case any Note is to be redeemed in part only, the portion of the
principal amount thereof to be redeemed and on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 

A Redemption Notice shall be irrevocable. 
 (d)
If fewer than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of a Global Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on
a pro rata basis or by another method the Trustee considers to be fair and appropriate; provided that, to the extent the Notes to be redeemed in part are represented by a Global Note, such method shall comply with the applicable
procedures of the Depositary. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be the portion
selected for redemption. In the event of any redemption in part, the Company shall not be required to (i) issue, register the transfer of or exchange any Notes during a period beginning at the open of business 15 calendar days before the
mailing of a Redemption Notice and ending at the close of business on the day of such mailing or (ii) register the transfer of or exchange any Notes so selected for redemption, in whole or in part, except the unredeemed portion of any Notes
being redeemed in part. 
 Section 16.03. Payment of Notes Called for Redemption.  

(a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 16.02, the Notes shall become due and payable on
the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and
redeemed by the Company at the applicable Redemption Price. 
 (b) Prior to the open of business on the Redemption Date, the Company shall
deposit with the Paying Agent or, if the Company is acting as the Paying Agent, shall set aside, segregate and hold in trust as provided in Section 4.04 an amount of cash (in immediately available funds if deposited on the Redemption Date),
sufficient to pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made promptly after the later of: 

(i) the Redemption Date for such Notes; and 

(ii) the time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder

appointment to all Holders as the names and addresses of such Holders appear on the Note Register.

authenticating agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 

The provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and this Section 17.10 shall be applicable to any authenticating
agent.

of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or
natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that are consistent with

 [FORM OF REVERSE OF NOTE] 

Insulet Corporation 
 1.25%
Convertible Senior Note due 2021 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 1.25% Convertible
Senior Notes due 2021 (the “Notes”), limited to the aggregate principal amount of $345,000,000 all issued or to be issued under and pursuant to an Indenture dated as of September 13, 2016 (the “Indenture”),
between the Company and Wells Fargo Bank, National Association (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. 

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes
may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and
certain exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will make all payments
and deliveries in respect of the Fundamental Change Purchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company
will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
 No
reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal (including the Redemption Price and the Fundamental
Change Purchase Price, if applicable) of and accrued and unpaid interest on, and to pay or deliver, as the case may be, the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money or
shares of the Common Stock, as the case may be, herein prescribed. 
 The Notes are issuable in registered form without coupons in
denominations of $1,000 principal amount and multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like
aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in
connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

The Notes shall be redeemable at the Company’s option in accordance with the terms and conditions specified in the Indenture. 

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to purchase for
cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or multiples thereof) on the Fundamental Change Purchase Date at a price equal to the Fundamental Change Purchase Price. 

  
 A-5 








 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option,
during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that
is $1,000 or a multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

 Terms used in this Note and defined in the Indenture are used herein as therein defined.
