 5 













 (c) the stockholders of the Company approve any plan or proposal for the
liquidation or dissolution of the Company; or 
 (d) the Common Stock (or other common stock, ordinary shares or shares of
Common Equity (or American depositary shares representing any of the foregoing) constituting Reference Property) ceases to be listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any
of their respective successors); 
 provided, however, that a transaction or transactions described in clause (a) and/or clause

Company, excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights, in connection with such transaction or transactions consists of shares of common stock, ordinary shares or shares of Common
Equity (or American depositary shares representing any of the foregoing), in each case that are listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective
successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions and as a result of such transaction or transactions the Notes become convertible into such consideration, excluding cash payments
for fractional shares and cash payments made pursuant to dissenters’ appraisal rights (subject to the provisions of Section 14.02(a)). If any transaction in which the Common Stock is replaced by the securities of another entity occurs,
following completion of any related Make-Whole Fundamental Change Period (or, in the case of a transaction that would have been a Fundamental Change or a Make-Whole Fundamental Change but for the proviso immediately following clause
(d) of the definition thereof, following the effective date of such transaction) references to the Company in this definition shall instead be references to such other entity. 

For purposes of this definition of “Fundamental Change” above, any transaction that constitutes a Fundamental Change pursuant to both clause
(a) and clause (b) of such definition (without giving effect to the proviso in clause (b)) shall be deemed a Fundamental Change solely under clause (b) of such definition (subject to the proviso in clause (b)). 

“Fundamental Change Company Notice” shall have the meaning specified in Section 15.02(c).

Restriction Termination Date”) that is the later of (1) the date that is one year after the last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and
(2) such later date, if any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof,
which shall bear the legend set forth in Section 2.05(d), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared
effective under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless
otherwise agreed by the Company in writing, with notice thereof to the Trustee in the form set forth in Exhibit B attached hereto): 
 THIS
SECURITY AND THE SHARES OF CLASS A COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED
OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 

(1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE
MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 

(2) AGREES FOR THE BENEFIT OF WAYFAIR INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE
TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY
SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

 (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

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

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on
the Form of Assignment and Transfer has been checked. 
 Any Note (or security issued in exchange or substitution therefor) (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 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 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 in writing (in the form set forth in Exhibit B) upon the occurrence of the Resale Restriction Termination Date and promptly
after a registration statement, if any, with respect to the Notes or any shares of Common Stock issued upon conversion of the Notes has been declared effective 

  
 19 













 
under the Securities Act. Upon notice of the Resale Restriction Termination Date, the legend set forth above shall be deemed removed from the Note, with no further action required by the Company,
the Trustee, or, if applicable, the Depositary; provided, however, that, if the mandatory exchange process of the Depositary is available therefor, the Company will use reasonable efforts to effect an exchange of every beneficial interest in
each Restricted Security for beneficial interests in Global Notes that are not subject to the restrictions set forth in the restrictive legend or this Section 2.05(c) pursuant to such process on or prior to the 380th day after the last date of
original issuance of the Notes. 
 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 exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding
paragraph. 
 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, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

  
 20 













 At such time as all interests in a Global Note have been converted, canceled, repurchased,
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, repurchased, 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. 

None of the Company, the Trustee or 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. Subject to its compliance with its obligations
under this Indenture, the Company shall have no responsibility or liability for any act or omission of the Depositary. 
 (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 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 WAYFAIR INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE
TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR 

  
 21 













 
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 CLASS A 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 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). 

(e) Any Note or share of 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 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 share of Common Stock, as the case may be, no longer being a “restricted security” (as defined under Rule 144). 

  
 22 













 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 its written 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. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required
in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is
about to mature or has been surrendered for required repurchase 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, payment, redemption, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the replacement, payment, redemption, conversion or repurchase of negotiable instruments or other securities without their surrender. 

  
 23 













 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 written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any
authorized denomination, and substantially in the form of the 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 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 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 at maturity, repurchase upon a Fundamental Change, redemption, registration of transfer or exchange or conversion, if surrendered to the Company or any of its agents, Subsidiaries or Affiliates, in each
case, that the Company controls, to be delivered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by it in accordance with its customary procedures. Except for Notes surrendered for transfer or exchange,
no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures. 

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; Repurchases. 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 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 shall have a separate CUSIP
number. 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


  
 24 













 
cover such matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, directly or
indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a privately negotiated transaction or public tender or exchange
offer or through counterparties to private agreements, including by cash-settled swaps or other cash-settled derivatives. The Company may, to the extent permitted by applicable law, reissue, resell or surrender to the Trustee for cancellation in
accordance with Section 2.08 any Notes that the Company may repurchase, in the case of a reissuance or resale, so long as such Notes do not constitute “restricted securities” (as defined under Rule 144) upon such resissuance or
resale. Any Notes that the Company may repurchase shall be considered outstanding for all purposes under this Indenture unless and until such time the Company surrenders them to the Trustee for cancellation in accordance with Section 2.08 and,
upon receipt of a written order from the Company, the Trustee shall cancel all Notes so surrendered. 
 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 Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) 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 on the Maturity Date, any Redemption Date, any Fundamental Change Repurchase 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 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

 25 













 Section 4.02. Maintenance of Office or Agency. The Company will maintain in the
contiguous United States, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion
Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office or the office or agency of the Trustee in the contiguous United States; provided, no service of legal process on the Company may be made at any office 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 the contiguous United States, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other
office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and Global Corporate
Trust Services, 100 Wall Street, Suite 1600, New York, New York 10005 as the office or agency in the Borough of Manhattan, The City of New York, where Notes may be surrendered for registration of transfer or exchange or for presentation for payment
or repurchase or for conversion and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. 

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 Repurchase 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 Repurchase 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. 

  
 26 













 The Company shall, on or before each due date of the principal (including the Redemption
Price and the Fundamental Change Repurchase 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
Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing of any failure to take such action; provided that if such deposit is made
on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date. 
 (b) If the Company
shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price and the Fundamental Change Repurchase 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 Repurchase 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 Repurchase 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.

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

  
 27 













 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. 

(b) The Company shall file with the Trustee, within 15 days after the same are required to be filed with the Commission, 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, for the avoidance of doubt, any such documents or reports, or portions thereof, subject to
confidential treatment and any correspondence with the Commission and giving effect to any grace period provided by Rule 12b-25 under the Exchange Act or any similar or successor grace period). 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, it
being understood that the Trustee shall have no responsibility to determine whether any documents have been filed on the EDGAR system. Notwithstanding anything to the contrary in this Indenture, the Company shall in no event be required to file
with, or otherwise provide or disclose to, the Trustee or any Holder any information for which the Company is seeking, or has received, confidential treatment from the Commission. 

(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), 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 preceding (as a result of restrictions pursuant to U.S.
securities laws or the terms of this Indenture or the Notes (other than any restriction arising solely from the Company’s or the Trustee’s ability to require the delivery of legal opinions, certificates or other evidence in order to
demonstrate that the proposed transfer is being made in compliance with applicable securities laws)), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of (i) 0.25% per annum of
the principal amount of the Notes outstanding for each of the first 90 days and (ii) 0.50% per annum of the principal amount of the Notes outstanding for each day from, and including, the 91st 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 have been the Company’s Affiliates at any


  
 28 













 
time during the three months preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes (other than any restriction arising solely from the
Company’s or the Trustee’s ability to require the delivery of legal opinions, certificates or other evidence in order to demonstrate that the proposed transfer is being made in compliance with applicable securities laws). 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. For purposes of this Section 4.06(d), the phrase “restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes” shall not include, for
the avoidance of doubt, the assignment of a restricted CUSIP or the existence of a restrictive legend on Notes in compliance with this Indenture, in either case, during the six-month period described in this
Section 4.06(d).

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

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

terms of this Indenture or the Notes). For the avoidance of doubt, a Global Note will not be deemed to be assigned an unrestricted CUSIP unless such Global Note is identified by an unrestricted CUSIP number in the facilities of the Depositary. 

(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, subject to
the immediately succeeding sentence, be in addition to, and not in lieu of, any Additional Interest that may be payable 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 timely file any document or report that it is required to file with the Securities and Exchange 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 filed on Form 8-K), as described in Section 4.06(d), together with any interest that may accrue in the event the Company elects to
pay Additional Interest in respect of an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) pursuant to Section 6.03, 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. 

  
 29 













 (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. 

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, 2018) an Officer’s Certificate stating whether 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 during such fiscal year 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 occurrence of any Event
of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or proposing to take in respect thereof. 

Section 4.09. Additional Amounts. 

(a) If the Company consolidates with or merges with or into, or sells, conveys, transfers or leases all or substantially all of the
Company’s properties and assets to, another company pursuant to Section 11.02, 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

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

any withholding or deduction as to which Additional Amounts would have otherwise been payable to such Holder or beneficial owner; 

  
 31 













 (B) any estate, inheritance, gift, sale, transfer, excise, personal property
or similar tax, assessment or other governmental charge;

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 enacted in any jurisdiction implementing FATCA, any intergovernmental agreement between the United States and any other jurisdiction to implement FATCA or any law enacted by such other jurisdiction to give
effect to such agreement, or any agreement with the U.S. Internal Revenue Service under FATCA; 
 (E) any tax, duty,
assessment or other governmental charge required to be withheld or deducted by any Paying Agent from any payment of principal of, or interest on, any Notes, if such payment could have been made without such withholding or deduction by at least one
other Paying Agent; 
 (F) any taxes imposed by the United States or any political subdivision thereof; or 

(G) any combination of taxes referred to in the preceding clauses (A), (B), (C), (D), (E), or (F), 

(ii) with respect to any payment of the principal of (including the Fundamental Change Repurchase 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) Reserved. 
 (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 or other evidence reasonably satisfactory to the Trustee.

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 Fundamental Change Repurchase Price and Redemption 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 4.09.

 Section 6.02. Acceleration; Rescission and Annulment. If 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 or 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 contained in this Indenture or in the Notes 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 or 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 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 to the extent that
payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes) 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 existing and past 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 continuing Default or Event of Default relating to (i) the nonpayment of
the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes or (ii) a failure to pay or deliver, as the case may be, the consideration due upon
conversion of the Notes. 

  
 35 













 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 (i) for the first 180 days
after the occurrence of such an Event of Default (beginning on, and including the date on which such an Event of Default first occurs), 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 such 180-day period on which such Event of Default is continuing and (ii) for the period from, and including, the 181st day after the
occurrence of such an Event of Default to, and including, the 360th day 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 0.50% per annum of the
principal amount of Notes outstanding for each day during such additional 180-day period on which such an Event of Default is continuing, subject to the second immediately succeeding paragraph. 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). If the Company so elects, such Additional Interest shall be
payable in the same manner and on the same dates as the stated interest payable on the 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 shall be immediately 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
elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 

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 immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent 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. 
 In no event
will the rate of any such Additional Interest payable pursuant to this Section 6.03, when taken together with any Additional Interest that may accrue as a result of the Company’s failure to timely file any document or report that it is
required to file with the Securities and Exchange 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), as described under Section 4.06(d), accrue at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. 

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 and be continuing, 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 

  
 36 













 
upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such
proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any
other obligor upon the Notes, wherever situated. 
 In the event there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company or any other Significant Subsidiary 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 Significant Subsidiary, the property of the Company or such other Significant Subsidiary, or in the event of any other judicial
proceedings relative to the Company or such other Significant Subsidiary upon the Notes, or to the creditors or property of the Company or such other Significant Subsidiary, 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. 

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. 

  
 37 













 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. 
 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 this Indenture; 
 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 Repurchase 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 Redemption Price, the Fundamental Change Repurchase Price and the 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 Redemption
Price and the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and 

  
 38 













 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 Repurchase 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 reasonably 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 (it being understood that the Trustee shall have no liability or responsibility to determine whether any such action is prejudicial to the Holders), or
to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise
provided herein). 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 Repurchase 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

 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 during the continuance of 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 the 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 existing or 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
Repurchase Price) of, the Notes when due that has not been cured, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes that has not been cured 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. 

  
 40 













 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, deliver to all Holders notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such
notice; provided that, except in the case of a Default in the payment of the principal of (including the Redemption Price and the Fundamental Change Repurchase 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 the Trustee 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 Repurchase Price, if applicable) on
or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions of Article 14. 

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 the event an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of 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 reasonably satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction. 

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly
negligent failure to act or its own willful misconduct, except that: 

  
 41 













 (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 gross negligence and willful misconduct on the part of the
Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture;
but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 

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

  
 42 













 
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 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
or transfer 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 or transfer agent. 

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 
 Section 7.02.
Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 7.01: 
 (a) the Trustee may conclusively rely and

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;

instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit,
and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the Company and shall incur no
liability of any kind by reason of such inquiry or investigation; 
 (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; 

  
 43 













 (f) the permissive rights of the Trustee enumerated herein shall not be construed as duties;

 (g) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture; 

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

(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. 
 In no event shall the Trustee be liable for any special, punitive,
indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than any such loss
or damage caused by the Trustee’s willful misconduct or gross negligence. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have
actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or by any Holder of the Notes. 

Section 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 Agents, 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
Common Stock to Be Held in Trust. All monies and 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 Common Stock held by the Trustee in

Company and the Trustee. 
  

  
 44 













 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 gross negligence or willful misconduct. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction
entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, claim (whether asserted by the Company, a Holder or any other Person), damage, liability or expense incurred without
gross 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 Indenture or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 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. 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 gross negligence or willful misconduct on the part of the 

  
 45 













 
Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the Trustee, and such Officer’s Certificate, in the absence of gross negligence and
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, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 

Section 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 delivering notice thereof to the Holders. 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 45 days after the delivery of such
notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor trustee (at the Company’s
expense), or any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, subject to the provisions of Section 6.11, on behalf of himself or herself and all others similarly
situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

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

(i) the Trustee shall 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 (or since the date of this Indenture) may, on 

  
 46 













 
behalf of himself or herself 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 ten 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 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 send or cause to be sent a 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 send
such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be sent at the expense of the Company. 

  
 47 













 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. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and
deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the
name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee
shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by
merger, conversion or consolidation. 
 Section 7.12. Trustee’s Application for Instructions from the
Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this
Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The
Trustee shall not be liable to the Company for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three
Business Days after the date any officer that the Company has indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to
taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 

ARTICLE 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 

  
 48 













 
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 the provisions of Article 9, 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, but shall not be required to, fix 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
Section 9.05, 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 in Section 9.06. 

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 (including any Redemption Price and any Fundamental Change Repurchase
Price) 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 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 Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any
Affiliate of the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of
this Section 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 

  
 49 













 
and that the pledgee is not the Company, a Subsidiary thereof or an Affiliate of the Company or a Subsidiary thereof. 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. 
 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

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

 Section 9.02. Call of Meetings by Trustee. The Trustee may at any time call a
meeting of Holders to take any action specified in Section 9.01, to be held at such time and at such place as the Trustee shall determine. Notice of every meeting of the Holders, setting forth the time and the place of such meeting and in
general terms the action proposed to be taken at such meeting and the establishment of any record date pursuant to Section 8.01, shall be delivered to Holders. Such notice shall also be delivered to the Company. Such notices shall be delivered
not less than 20 nor more than 90 days prior to the date fixed for the meeting. 
 Any meeting of Holders shall be valid without notice if
the Holders of all Notes then outstanding are present in person or by proxy or if notice is waived before or after the meeting by the Holders of all Notes then outstanding, and if the Company and the Trustee are either present by duly authorized
representatives or have, before or after the meeting, waived notice. 
 Section 9.03. Call of Meetings by Company or Holders. In
case at any time the Company, pursuant to a Board Resolution, or the Holders of at least 10% of the aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting
forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have delivered the notice of such meeting within 20 days after receipt of such request, then the Company or such Holders may determine the time and

entitled to be present or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company and its counsel. 

Section 9.05. Regulations. Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable

proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 9.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the
meeting shall be elected by vote of the Holders of a majority in aggregate principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 

Subject to the provisions of Section 8.04, at any meeting of Holders each Holder or proxyholder shall be entitled to one vote for each
$1,000 principal amount of Notes held or represented by him or her; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the chairman of the


  
 51 













 
meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating it as the
proxy to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 9.02 or Section 9.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of
Notes represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice.

shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of the
proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more
Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was delivered as provided in Section 9.02. The record shall show the aggregate principal amount of the Notes voting in favor of
or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by
the Trustee, the latter to have attached thereto the ballots voted at the meeting. 
 Any record so signed and verified shall be conclusive
evidence of the matters therein stated. 
 Section 9.07. No Delay of Rights by Meeting. Nothing contained in this Article 9
shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred
upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Notes.

Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental
indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own
rights, duties or immunities under this Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this
Section 10.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 

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 repurchase of, or tender or exchange

 53 













 
Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions

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. 

  
 54 













 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 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 it 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 all or substantially all of its properties and assets to another Person (other than in a Permitted Sale Transaction), unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be (i) a
corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia or (ii) a corporation or entity that is treated as a corporation for U.S. federal income tax purposes organized and
existing under the laws of the Cayman Islands, the British Virgin Islands, the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, and the Successor Company (if not the
Company) shall expressly assume, by supplemental indenture 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 4.09);
and 
 (b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under
this Indenture. 

  
 55 













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

Section 11.02. Successor Person 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, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had
been named herein as the party of the first part, and the Company (except in the case of a lease of all or substantially all of the Company’s property and assets) shall be discharged from the obligations of the Company under the Notes and this
Indenture. 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 such 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 and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 11.

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

or of any successor Person, either directly or through the Company or any successor Person, 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

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 an integral 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 August 1, 2024 under the circumstances and during the periods set forth in Section 14.01(b), and (ii) regardless
of the conditions described in Section 14.01(b), on or after August 1, 2024 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
8.5910 shares of Common Stock (subject to adjustment as provided in this Article 14, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.02,
the “Conversion Obligation”). 
 (b) (i) Prior to the close of business on the Business Day immediately preceding
August 1, 2024, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any ten 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 on each such Trading Day and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent 

  
 57 













 
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 or an Affiliate thereof) 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, 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 (1) a Holder of at least $2,000,000 aggregate principal amount of Notes provides the
Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the Conversion Rate on
such Trading Day and (2) such Holder requests that the Company requests that the Bid Solicitation Agent determine, or, if the Company is acting as Bid Solicitation Agent, requests that the Company determine, the Trading Price per $1,000
principal amount of Notes, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000
principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until 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 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 Conversion
Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee). 

(ii) If, prior to the close of business on the Business Day immediately preceding August 1, 2024, the Company elects to:

 (A) issue to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to
a stockholders rights plan, prior to the separation thereof from the Common Stock) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a
price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance;
or 

  
 58 













 (B) distribute to all or substantially all holders of the Common Stock the
Company’s assets, securities or rights to purchase securities of the Company (other than pursuant to a stockholders rights plan, prior to the separation thereof from the Common Stock), which distribution has a per share value, as reasonably
determined by the Company, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement 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) either (x) at
least 40 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution (or, if later in the case of any such separation of rights issued pursuant to a stockholder rights plan, as soon
as reasonably practicable after the Company becomes aware that such separately has occurred or will occur) or (y) at least 15 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or
distribution; provided that, if the Company provides such notice in accordance with this clause (y) but not in accordance with the immediately preceding clause (x), notwithstanding anything to the contrary under Section 14.02 or any
other provision of this Indenture, the Company shall be required to settle all conversions of Notes with a Conversion Date occurring during the period from, and including, the date of such notice to, and including, the
Ex-Dividend Date for such issuance or distribution using Physical Settlement and the Company shall so notify the Holders in such notice. Once the Company has given such notice, a Holder may surrender all or
any portion of its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and
(2) the Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time. Holders of the Notes may not exercise the right to convert pursuant to this
Section 14.01(b)(ii) if they participate, at the same time and upon the same terms as holders of Common Stock and solely as a result of holding the Notes, in any of the transactions described above without having to convert their Notes as if
they held a number of shares of Common Stock equal to the applicable Conversion Rate as of the Record Date for such issuance or distribution multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

(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 August 1, 2024, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or if the Company is a party to a Merger
Event (other than a Merger Event that is solely for the purpose of changing the Company’s jurisdiction of organization that (x) does not constitute a Fundamental Change or a Make-Whole Fundamental Change and (y) results in a
reclassification, conversion or exchange of outstanding shares of the Common Stock solely into shares of common stock of the surviving entity and such common stock becomes Reference Property for the Notes) that occurs prior to the close of business
on the Business Day immediately preceding August 1, 2024, all or any portion of a Holder’s 

  
 59 













 
Notes may be surrendered for conversion at any time from or after the effective date of such transaction or event until the earlier of (x) 35 Trading Days after the effective date of such
transaction or event, if such transaction or event also constitutes a Fundamental Change (other than a Fundamental Change for which the Company validly invokes the Adequate Cash Conversion Provisions), until the close of business on the Business Day
immediately prior to the related Fundamental Change Repurchase Date and (y) the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date. The Company shall notify Holders, the Trustee and the Conversion
Agent (if other than the Trustee) within five Business Days of such transaction or event. 
 (iv) Prior to the close of
business on the Business Day immediately preceding August 1, 2024, a Holder may surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on December 31,
2018 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the
immediately preceding calendar quarter is greater than 130% of the Conversion Price on each applicable Trading Day. 
 (v) If
the Company calls any or all of the Notes for Optional Redemption pursuant to Article 16 prior to the close of business on the Business Day immediately preceding August 1, 2024, then a Holder may surrender for conversion all or any portion of
its Notes called for Optional Redemption at any time prior to the close of business on the second Scheduled Trading Day prior to the Redemption Date, even if the Notes called for Optional Redemption are not otherwise convertible at such time. After
that time, the right to convert shall expire, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes called for Optional Redemption may convert its Notes called for Optional Redemption until the
Redemption Price has been paid or duly provided for. Notwithstanding the foregoing, if the Company calls less than all outstanding Notes for Optional Redemption and a Holder (including, for this purpose, the owner of a beneficial interest in a
Global Note) is not able to reasonably determine, prior to the close of business on the 33rd Scheduled Trading Day immediately preceding the relevant Redemption Date, whether the Notes owned by such Holder (or beneficially owned by such owner of a
beneficial interest, as applicable) are subject to such partial Optional Redemption (and, as a result thereof, convertible in accordance with this Section 14.01(b)(v)) for any reason, then such Holder (or such owner of a beneficial interest, as
applicable) shall be entitled to convert such Notes after the date of the Notice of Redemption until the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date, regardless of whether such Notes (or such
beneficial interests, as applicable) are subject to such partial Optional Redemption, and any such conversion will be deemed to be of a Note called for Optional Redemption for purposes of Section 14.03.

 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 amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering
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
delivering 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 for which the relevant Conversion Date occurs on or after August 1, 2024, and all conversions for
which the relevant Conversion Date occurs after the Company’s issuance of a Notice of Redemption with respect to any Notes and prior to the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date,
shall be settled using the same Settlement Method. 
 (ii) Except for any conversions for which the relevant Conversion Date
occurs after the Company’s issuance of a Notice of Redemption with respect to any Notes but prior to the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date and any conversions for which the
relevant Conversion Date occurs on or after August 1, 2024, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with
respect to conversions with different Conversion Dates. 
 (iii) If, in respect of any Conversion Date (or the period
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 for which the relevant Conversion Date occurs (x) after the date of issuance of a Notice of Redemption with respect to the Notes and prior to the close of business on the second Scheduled Trading Day immediately preceding the
related Redemption Date, in such Notice of Redemption or (y) on or after August 1, 2024, no later than August 15, 2024). 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 per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of
Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. 

  
 61 













 (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 in respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date; 

(B) if the Company elects (or is deemed to have elected) 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 30 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 30 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. 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 

  
 62 













 
(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, pay all applicable transfer or similar taxes,
if any, pursuant to Section 14.02(e), (4) if required, furnish appropriate endorsements and transfer documents and (5) 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 Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase 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 second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the second 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 (if applicable) to the Conversion Agent or to such
Holder, or such Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in certificate form or in book-entry format, 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 documentary, stamp or similar issue or 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 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. 

  
 63 













 (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 full 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 relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant 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 after the close of business on the Regular Record Date immediately preceding the Maturity Date;
(2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; (3) if the Company has specified a
Redemption Date that is after a Regular Record Date and on or prior to the second Scheduled Trading Day immediately following the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts
exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all applicable Holders of record at the close of business on the Regular Record Date immediately preceding the Maturity Date or any Redemption Date
shall receive the full interest payment due on the Maturity Date or any Redemption Date, as the case may be, regardless of whether their Notes have been converted following such Regular Record Date. 

(i) The Person in whose name any shares of Common Stock shall be issuable upon conversion 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. 

  
 64 













 (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 for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for the
last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each 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 relevant 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 or
Notice of Redemption. (a) If (x) the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date or (y) the Company gives a Notice of Redemption with respect to such notes called for Optional Redemption in
accordance with Article 16 (provided that, if the Company sends a Notice of Redemption for less than all of the Notes outstanding, then the Conversion Rate will be increased as set forth herein only with respect to the Notes called for
Optional Redemption that are converted in connection therewith, and not with respect to the Notes not called for Optional Redemption, so that in that circumstance, Holders of Notes not called for Optional Redemption will not be entitled to an
increased Conversion Rate for such Notes as set forth in this Section 14.03 on account of the Optional Redemption; provided further that, notwithstanding the foregoing and for the avoidance of doubt, Notes (or beneficial interests in a
Global Note, as applicable) that are deemed to be called for such partial Optional Redemption in the circumstances described under Section 14.01(b)(v) and are converted in connection therewith in accordance with the provisions of this Article
14 will be entitled to an increased Conversion Rate for such Notes as set forth herein on account of such deemed partial Optional Redemption) and, (b) a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or
in connection with such Notice of Redemption, as applicable, 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 Make-Whole Fundamental Change up to, and including, the close of business on the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a
Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof or the Adequate Cash Conversion Provisions, the 35th Trading Day immediately following the Effective Date
of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”). A conversion of Notes shall be deemed for these purposes to be “in connection with” a Notice of Redemption and solely with
respect to Notes called for Optional Redemption thereby (including, for the avoidance of doubt, in the case of a partial Optional Redemption, Notes (or beneficial interests in a Global Note, as applicable) deemed to be called for such partial
Optional Redemption in the 

  
 65 













 
circumstances described under 14.01(b)(v)) if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the date the Company issues the Notice of Redemption until
the close of business on the second Scheduled Trading Day immediately preceding the corresponding Redemption Date. 
 (b) Upon surrender of
Notes for conversion in connection with a Make-Whole Fundamental Change or a Notice of Redemption, 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 following such
Make-Whole Fundamental Change 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 second Business Day following the Conversion Date. The Company shall notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change no later than five Business
Days after such Effective Date. 
 (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be
determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective or the date of the relevant Notice of Redemption, as the case may be (in each case, the “Effective
Date”) and the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change or with respect to the Notice of Redemption, as the case may be (the “Stock Price”). If the holders of the
Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price for such Make-Whole Fundamental Change shall be the cash
amount paid per share. Otherwise, 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 or the date of the Notice of Redemption, as the case may be. The Company 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 such term is used in Section 14.04) or expiration date of the event occurs
during such five consecutive Trading Day period. In the event that a conversion of the Notes in connection with a Notice of Redemption would also be deemed to be in connection with a Make-Whole Fundamental Change, a Holder of the Notes to be
converted shall be entitled solely to a single increase to the Conversion Rate with respect to the first to occur of the applicable date of the Notice of Redemption or the Effective Date of the applicable Make-Whole Fundamental Change, and the later
event shall be deemed not to have occurred for purposes of this Section 14.03. 

  
 66 













 (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 or 366-day year, as applicable; 

(ii) if the Stock Price is greater than $575.00 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 $87.85 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 per $1,000 principal amount of Notes exceed 11.3830 shares of Common Stock, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 

  
 67 













 (f) 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 (other than in the case
of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this
Section 14.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

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





 
 where, 
  

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

 Any adjustment made under this Section 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. 

  
 68 













 (b) If the Company issues to all or substantially all holders of the Common Stock any
rights, options or warrants (other than pursuant to a stockholders rights plan) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a
price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance,
the Conversion Rate shall be increased based on the following formula: 
  
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive
Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants
are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such
rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered. If no such rights, options or warrants are issued, or if no such rights, options or warrants are exercised prior to their expiration, the Conversion Rate shall be decreased to the Conversion Rate
that would then be in effect if such Ex-Dividend Date for such issuance had not occurred. 

  
 69 













 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 Common Stock at a price per share that is 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 date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there
shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Company
in good faith. 
 (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the
Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances described in Section 14.04(a) or
Section 14.04(b), (ii) rights issued under a stockholders rights plan prior to separation thereof from the shares of Common Stock in the circumstances described in Section 14.11, (iii) dividends or distributions paid exclusively in cash
described in Section 14.04(d), (iv) distributions of Reference Property upon conversion of, or in exchange for, Common Stock in a transaction described in Section 14.07(a), and (v) 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, the “Distributed
Property”), then the Conversion Rate shall be increased based on the following formula: 
  
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 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 in good faith by the Company) of the Distributed Property with respect to each outstanding share of Common Stock 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 

  
 70 













 
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. 

With respect to an adjustment pursuant to this Section 14.04(c) where there has been a payment of a dividend or other distribution on the
Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national
securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
  





 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of Common Stock (determined by reference to the definition of Last
Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The increase to the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the Valuation Period;
provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references in the portion of this Section 14.04(c) related to
Spin-Offs to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the
Conversion Date in determining the Conversion Rate 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 Valuation Period, references in the portion of this Section 14.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day of such Observation Period. 

 

  
 71 













 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 the 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 Common Stock; (ii) are not exercisable; and
(iii) are also issued in respect of future issuances of 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, 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), if any dividend or distribution to which this
Section 14.04(c) is applicable 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 

  
 72 













 (B) a dividend or distribution of rights, options or warrants to which Section 14.04(b)
is applicable (the “Clause B Distribution”), then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which
this Section 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 such Ex-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b). 
 (d) If any cash dividend or
distribution is made to all or substantially all holders of the Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  





 
 where, 
  

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

 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 be 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
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. 

  
 73 













 (e) If the Company or any of its Subsidiaries make a payment in respect of a tender or
exchange offer for the Common Stock that is subject to the then-applicable tender offer rules under the Exchange Act (other than an odd-lot tender offer), to the extent that the cash and value of any other
consideration included in the payment per share of 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 Conversion Rate shall be increased based on the following formula: 
  





 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Company in good faith) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such
tender or exchange offer);
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or
exchange offer); and
			
	SP1	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 The increase to the Conversion Rate under this Section 14.04(e) shall occur at the close of business on the 10th Trading
Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (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 Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section 14.04(e)


  
 74 













 
with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange offer expires and the Conversion
Date in determining the Conversion Rate 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 Trading Day next succeeding the expiration date of any tender or exchange offer, 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 expiration date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day. 

In the event that the Company or one of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender offer or exchange offer described
in this clause (e) but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchase or any such purchase is rescinded, the applicable Conversion Rate shall be decreased to be the Conversion Rate
that would then be in effect if such tender or exchange offer had not been made or had not 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 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 shares of the Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 

(g) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if a Holder converts a Note, Combination
Settlement is applicable to such Note and the Daily Settlement Amount for any Trading Day during the Observation Period applicable to such Note (i) is calculated based on a Conversion Rate adjusted on account of any event described in clause
(a) through (e) of this Section 14.04 and (ii) includes any shares of Common Stock that entitle their holder to participate in such event, then, notwithstanding the adjustment required by clause (a), (b), (c), (d) or (e) of this
Section 14.04, as the case may be, such Conversion Rate adjustment shall not be made for such converting Holder for such Trading Day in respect of the portion of the Conversion Obligation comprised of such shares of Common Stock. Instead, such
Holder shall be treated as if such Holder were the record owner of such shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 

(h) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities
convertible into or exchangeable for Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. 

  
 75 













 (i) 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 (but is not required to)
increase the Conversion Rate by any amount for a period of at least 20 Business Days (i) if the Company determines that such increase would be in the Company’s best interest or (ii) to avoid or diminish any income tax to holders of
Common Stock or rights to purchase shares of 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
the preceding sentence, the Company shall deliver to the Holder of each Note 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. 
 (j) Except as described in this Section 14.04 and Section 14.03, the Conversion Rate
shall not be required to be adjusted for any transaction or event. Without limiting the foregoing, the Conversion Rate shall not be required to be adjusted: 

(i) upon the issuance of shares of Common Stock at a price below the Conversion Price; 

(ii) 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; 

(iii) 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; 

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

(v) for a third-party tender offer other than as described in Section 14.04(e); 

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

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

(k) 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. The Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate. However,
the Company shall carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustments (1) upon conversion of any Note (x) if Cash Settlement or Combination Settlement is applicable to such
conversion, on each Trading Day in the Observation Period for such conversion and (y) if Physical Settlement is applicable to such conversion, on the relevant Conversion Date and (2) on each anniversary of the original issue date of the
Notes, in each case, without duplication and regardless of whether the aggregate adjustment is less than 1%. 

  
 76 













 (l) 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 deliver such notice of such adjustment of the Conversion Rate to each Holder. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

(m) 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 the 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 or Optional Redemption), the Company shall make adjustments in its good faith judgment 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, as the case may be, 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. 
 For the
avoidance of doubt, the adjustments made pursuant to this Section 14.05 shall be made solely to the extent that the Company determines in its good faith judgment that any such adjustment is appropriate, without duplication of any adjustment
made pursuant to Section 14.04. 
 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 delivery of the maximum
number of Additional Shares pursuant to Section 14.03 and 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 were applicable). 

  
 77 













 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 in par value or from no par value
or resulting from a subdivision or combination), 
 (ii) any consolidation, merger, combination or similar transaction
involving the Company, 
 (iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company
and the Company’s Subsidiaries substantially as an entirety or 
 (iv) any statutory share exchange, 

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including
cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of 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(g) 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 or the successor or acquiring Person, as the case may be, 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 

  
 78 













 
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 of the Common Stock receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of
such Merger Event (A) 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 (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second Business Day
immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as reasonably practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other 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, securities or other property or assets (including cash or any
combination thereof) of a Person other than the successor or purchasing Person, 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 Company shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 15. 

(b) When the Company executes 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 a unit of 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 delivered to each
Holder within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

(c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 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. 

  
 79 













 (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 of Common Stock 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 use reasonable best efforts to list and keep listed, so long as the Common Stock shall be so
listed on such exchange or automated quotation system, any shares of 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). 

  
 80 













 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 

(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 sent 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. If the Company
has a stockholder 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 shares of
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. However, if, prior to any conversion of
Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or
substantially all holders of the 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 (an “Exchange Election”), direct the Conversion Agent to surrender, on or prior to the Trading Day immediately following the Conversion Date, such Notes to one or more financial institutions designated by the Company
for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution(s) must agree to timely pay or deliver, in exchange for such Notes, cash, shares of Common Stock or a combination of
cash and shares of Common Stock, at the Company’s election, that would otherwise be due upon conversion as described under Section 14.02. If the Company makes an Exchange Election, it shall, by the close of business on the Trading Day
immediately following the relevant Conversion Date, notify the Holder surrendering its Notes for conversion that it has made such Exchange Election and notify the designated financial institution(s) of the relevant deadline for payment or delivery,
as the case may be, of the conversion consideration and the type of conversion consideration to be paid or delivered, as the case may be. 

  
 81 













 (b) Any Notes exchanged by the designated financial institution(s) shall remain outstanding.
If the designated financial institution(s) agree(s) to accept any Notes for exchange but does not timely pay or deliver, as the case may be, the related conversion consideration, or if such designated financial institution(s) does not accept the
Notes for exchange, the Company shall pay or deliver, as the case may be, the relevant consideration due in respect of the Conversion Obligation, as, and at the time, required pursuant to this Indenture as if the Company had not made an Exchange
Election. So long as the Notes are eligible for book-entry settlement with the Depositary, the Company shall comply with the applicable procedures of the Depositary. 

(c) The Company’s designation of any financial institution(s) to which the Notes may be submitted for exchange does not require such
institution(s) to accept any Notes. The Company may, but will not be obligated to, pay any consideration to, or otherwise enter into any agreement with, the designated financial institution(s) for or with respect to such designation.

HOLDERS 
 Section 15.01. [Intentionally Omitted].  

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any
time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the
“Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of
the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls
after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular
Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15. The Fundamental Change Repurchase Date shall be subject to postponement in order to allow
the Company to comply with applicable law as a result of changes to such applicable law occurring after the date of this Indenture.
 (b)
Repurchases 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 Repurchase 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 on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase
Date; and 

  
 82 













 (ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying
Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) and on or prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase
Date at the 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 Repurchase Price therefor. 
 The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state: 

(i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase; 

(ii) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

 (iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this
Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate
Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change
Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03. 

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of
withdrawal thereof. 
 (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 notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the
Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in
accordance with the applicable procedures of the Depositary. Each Fundamental Change Company Notice shall specify: 

  
 83 













 (i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 15; 

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase 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; 

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be
converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and 

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes; 

provided, however, that, if the Notes are Global Notes, the Holders (and holders of a beneficial interest in such Global Notes) must
comply with the applicable procedures of the Depositary. 
 No failure of the Company to give the foregoing notices and no defect therein
shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02. 

At the Company’s 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, the Company shall not be required to purchase, or to make an offer to purchase, the Notes upon a Fundamental Change if a third party makes such an offer in the same manner, at the same time and otherwise in compliance
with the requirements for an offer made by the Company as set forth above, and such third party purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with
the requirements for an offer made by the Company as set forth above. 

  
 84 













 (e) Notwithstanding the foregoing, the Company shall not be required to give such notice or
repurchase the Notes as described above upon a Fundamental Change pursuant to clause (b) of the definition thereof if (1) such Fundamental Change results in the Notes becoming convertible (pursuant to Section 14.07) into an amount of
cash per Note greater than the Fundamental Change Repurchase Price (assuming the maximum amount of accrued interest would be payable based on the latest possible Fundamental Change Repurchase Date) and (2) the Company provides timely notice of
the Holders’ right to convert their Notes based on such Fundamental Change as described in Section 14.01(b)(iii). The provisions set forth in this (e) are referred to in this Indenture as the “Adequate Cash Conversion
Provisions.” 
 (f) Notwithstanding the foregoing, no Notes may be repurchased 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 Repurchase 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 Repurchase 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 Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 15.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be
withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the 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 Repurchase Date, specifying: 
 (i) the principal amount of the Notes with respect to which such
notice of withdrawal is being submitted (which must be $1,000 or an integral multiple thereof), 
 (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 (which must be $1,000 or an integral multiple thereof), of such Note that remains subject to
the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 

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

Section 15.04. Deposit of Fundamental Change Repurchase 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 Repurchase Date an
amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or 

  
 85 













 
Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the close of business on the Business Day
immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date (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 Repurchase Price. 

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the
Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been properly surrendered for repurchase and have
not been validly withdrawn, (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 Repurchase Price and, if applicable, accrued and unpaid interest). 

(c) Upon surrender of a Physical Note that is to be repurchased 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 unrepurchased portion of the Note surrendered. 

Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer pursuant
to a Fundamental Change Repurchase Notice, the Company will, if required: 
 (a) comply with any tender offer rules under the Exchange Act
that may then be applicable; 
 (b) file a Schedule TO or any other required schedule under the Exchange Act; and 

(c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase 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. To
the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture relating to the Company’s obligations to purchase the Notes upon a Fundamental Change, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have breached its obligations under such provisions of this Indenture by virtue of such conflict.

 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 May 8, 2022. On or after May 8, 2022, the Company may redeem, at its option, (an “Optional Redemption”), for cash, all or any portion of the Notes, at the Redemption Price, 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), including at least one of the five Trading Days immediately preceding the date on which the Company provides the
Notice of Redemption in accordance with Section 16.02, during any 30 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date on which the Company provides the Notice of Redemption in accordance
with Section 16.02. 
 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 shall deliver or cause to be
delivered a notice of such Optional Redemption (a “Notice of Redemption”) not less than 40 nor more than 50 Scheduled Trading Days prior to the Redemption Date to the Trustee, the Paying Agent (if other than the Trustee) and each
Holder of Notes. The Redemption Date must be a Business Day. The Company shall not specify a Redemption Date that falls on or after the 31st Scheduled Trading Day immediately preceding the Maturity Date. 

(b) Each Notice of Redemption shall identify the provision of this Indenture permitting Optional Redemption and shall specify: 

(i) the Redemption Date; 

(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 the Redemption Date unless the Company defaults in the payment of the Redemption Price; 

(iv) the place or places where such Notes subject to Optional Redemption are to be surrendered for payment of the Redemption
Price; 
 (v) that Holders may surrender Notes subject to such Optional Redemption for conversion at any time prior to the
close of business on the second scheduled Trading Day immediately preceding the Redemption Date (unless the Company fails to pay the Redemption Price, in which case a Holder of Notes subject to such Optional Redemption may convert such Notes until
the Business Day immediately preceding the date on which the Redemption Price has been paid or duly provided for); 

  
 87 













 (vi) the procedures a converting Holder must follow to convert its Notes
subject to Optional Redemption 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 subject to Optional Redemption and that no
representation is made as to the correctness or accuracy of the CUSIP or ISIN number listed in such notice or printed on the Notes; and 

(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, and that upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 

A Notice of Redemption shall be irrevocable. At the Company’s prior written request, the Trustee shall give the Notice of Redemption in
the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee not later than the close of business the Business Day prior to the date the Notice of Redemption is to be sent (unless
a shorter period shall be satisfactory to the Trustee), an Officer’s Certificate and a Company Order requesting that the Trustee give such Notice of Redemption together with the Notice of Redemption to be given setting forth the information to
be stated therein as provided in the preceding paragraph. The Notice of Redemption, if given 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 Notice of Redemption or any defect in the Notice of Redemption to the Holder of any Note designated for Optional Redemption as a whole or in part shall not affect the validity of the proceedings for the Optional Redemption of any other
Note. 
 (c) If fewer than all of the outstanding Notes are to be redeemed, (i) if the Notes to be redeemed are Physical Notes, the
Trustee shall select the Notes or portions thereof to be redeemed (in principal amounts of $1,000 or integral multiples of $1,000 in excess thereof) by lot, on a pro rata basis or by another method the Trustee considers to be fair and appropriate,
and in the case of the Global Note, in accordance with, and subject to, the Applicable Procedures. 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. 
 Section 16.03. Payment of Notes Called for
Redemption. (a) If any Notice of Redemption 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 Notice of
Redemption and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Notice of Redemption, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price. 

  
 88

deposit with the Paying Agent or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 7.05 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 on the Redemption Date for such
Notes. The Paying Agent shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price. 

Section 16.04. Restrictions on Redemption. The Company may not redeem any Notes on any date if the principal amount of the Notes
has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded on or prior to the Redemption Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the
Redemption Price with respect to such Notes).

Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee
hereunder pursuant to Section 7.08.

 Any corporation or other entity into which any authenticating agent may be merged or

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

 Section 17.11. Execution in Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute
effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original
signatures for all purposes. 
 Section 17.12. Severability. In the event any provision of this Indenture or in the Notes shall
be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired.

 Section 17.13. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

Section 17.14. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance
of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or
natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that are consistent with
accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 
 Section 17.15.
Calculations. Except as otherwise provided herein, the Company shall be responsible for making all calculations called for under the Notes. These calculations include, but are not limited to, determinations of the Last Reported Sale Prices of
the Common Stock, the Daily VWAPs, the Daily Conversion Values, the Daily Settlement Amounts, accrued interest payable on the Notes, Additional Interest and the Conversion Rate of the Notes. The Company shall make all these calculations in good
faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders of Notes. The Company shall provide a schedule of its calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and
Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder of Notes upon the request of that Holder
at the sole cost and expense of the Company. 
 Section 17.16. USA PATRIOT Act. The parties hereto acknowledge that in
accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies
each person or legal entity that establishes a relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the
requirements of the USA PATRIOT Act. 
 Section 17.17. Withholding Taxes. If the Company or other applicable withholding agent
pays withholding taxes or backup withholding on behalf of the Holder or beneficial owner as a result of an adjustment to the Conversion Rate, the Company or other applicable withholding agent may, at its option, set off such payments against
payments of cash and shares of Common Stock on the Note.

 [FORM OF REVERSE OF NOTE] 

Wayfair Inc. 
 1.125% Convertible
Senior Note due 2024 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 1.125% Convertible Senior
Notes due 2024 (the “Notes”), limited to the aggregate principal amount of $500,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Purchasers pursuant to the exercise
of their over-allotment option as set forth in the Purchase Agreement) all issued or to be issued under and pursuant to an Indenture dated as of November 19, 2018 (the “Indenture”), between the Company and U.S. 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. Capitalized terms used in this Note and not defined in this Note shall
have the respective meanings set forth in the Indenture. 
 In case certain Events of Default 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 Repurchase Price on the Fundamental Change Repurchase Date (if applicable), the Redemption Price on any Redemption Date (if applicable) 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 existing or 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 or deliver, as the case may be, the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on, and the consideration due upon
conversion of, this Note at the place, at the respective times, at the rate and in the lawful money and/or shares of Common Stock, as the case may be, herein prescribed. 

  
 A-6 













 The Notes are issuable in registered form without coupons in denominations of $1,000
principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal
amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any 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 are not subject to redemption prior to May 8, 2022. The Notes shall be redeemable at the Company’s option on or after
May 8, 2022 in accordance with the terms and subject to the conditions specified in the Indenture. No sinking fund is provided for the Notes. 

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option and subject to the limitations set forth
in the Indenture, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the
Fundamental Change Repurchase Price. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, 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 an integral multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable and subject to the limitations set forth in the Indenture, in each case at the Conversion Rate specified in
the Indenture, as adjusted from time to time as provided in the Indenture.
