such consideration, excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ statutory appraisal rights (subject to the provisions of Section 14.02(a)). If any transaction in which the Common Stock is

Section 2.05(d), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those contained in the legend set forth below), unless such
restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer.

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): 

THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN 

  
 18 













 
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 CRYOLIFE, 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.* 

 

	*	 This paragraph and the immediately preceding paragraph will be deemed to be removed from the face of this Note
at such time when the Company delivers written notice to the Trustee of such deemed removal pursuant to Section 2.05(f) of the within-mentioned Indenture. 



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 

  
 19 













 
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 after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

 Notwithstanding any other provisions of this Indenture, 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 Officers’ Certificate, an Opinion of Counsel 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. 

  
 20 













 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. 

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 (acting in any
capacity) 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, or for any action or inaction 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 

  
 21 













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

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

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

(D)    PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY
OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN
ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO
DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT. 
 Any such Common Stock (i) as to which such restrictions on transfer shall have expired in accordance with their terms,
(ii) that has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to
the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of
the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.05(d). 

  
 22 













 (e)    Any Note or Common Stock issued upon the conversion or exchange
of a Note that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months immediately preceding) may not be resold by such Affiliate (or such Person, as the case may
be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a
“restricted security” (as defined under Rule 144). The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.08. 

(f)    Without limiting the generality of any other provision of this Indenture (including Section 4.06), the legend
affixed to any Note pursuant to Section 2.05(c) will be deemed, pursuant to this Section 2.05(f) and the footnote to such legend, to be removed therefrom upon the Company’s delivery to the Trustee of notice, signed on behalf of the
Company by one (1) of its Officers, to such effect (and, for the avoidance of doubt, such notice need not be accompanied by an Officers’ Certificate or an Opinion of Counsel in order to be effective to cause such legend to be deemed to be
removed from such Note). If such Note bears a “restricted” CUSIP or ISIN number at the time of such delivery, then, upon such delivery, such Note will be deemed, pursuant to this Section 2.05(f) and the footnotes to the CUSIP and ISIN
numbers set forth on the face of the certificate representing such Note, to thereafter bear the “unrestricted” CUSIP and ISIN numbers identified in such footnotes; provided, however, that if such Note is a Global Note and the
Depositary thereof requires a mandatory exchange or other procedure to cause such Global Note to be identified by “unrestricted” CUSIP and ISIN numbers in the facilities of such Depositary, then (i) the Company will effect such
exchange or procedure as soon as reasonably practicable; and (ii) for purposes of Section 4.06, such Global Note will not be deemed to be identified by “unrestricted” CUSIP and ISIN numbers until such time as such exchange or
procedure is effected. 
 Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or
be destroyed, lost or stolen, and neither the Company nor the Trustee receives notice that such Note has been acquired by a protected purchaser, 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 Company may charge for its expenses (including the expenses of the Trustee and, if applicable, to such
authenticating agent) in replacing a Note. 

  
 23 













 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 redemption or 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 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. 

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 

  
 24 













 
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 repurchased by the Company to be
surrendered to the Trustee for cancellation. All Notes so surrendered to the Trustee shall be canceled promptly by it. Except for any Notes surrendered for registration of transfer or exchange, or as otherwise expressly permitted by any of the
provisions of this Indenture, no Notes shall be authenticated in exchange for any Notes surrendered to the Trustee for cancellation. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition,
shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order. 
 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 date, 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 and securities law purposes, such additional Notes shall have one or more separate CUSIP numbers. Prior to the issuance of any such additional Notes, the Company shall
deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 17.05 and
Section 17.06, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), 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 derivatives,
in each case without prior notice to Holders.

 ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01. Satisfaction and Discharge. This Indenture and the Notes shall upon request of the Company contained in an Officers’
Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore authenticated and
delivered (other than 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, 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 Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding
the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive. 

ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

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

Section 4.02. Maintenance of Office or Agency. The Company will maintain in 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, redemption 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 (not including service of process) may be made or served at the Corporate Trust Office or
the office or agency of the Trustee in the contiguous United States. 
 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 

  
 26 













 
written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and
“Conversion Agent” include any such additional or other offices or agencies, as applicable. 
 The Company hereby initially
designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office as the office or agency in the contiguous United States, where Notes may be surrendered for registration of transfer or
exchange or for presentation for payment, redemption 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; 

(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. 
 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 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 

  
 27 













 
hold in trust for the benefit of the Holders 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. 
 (d)    Subject to any applicable abandoned property
law, any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if
applicable) of, accrued and unpaid interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if
applicable), interest or consideration due upon conversion has become due and payable shall be paid to the Company on request of the Company contained in an Officers’ Certificate, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money and shares of Common Stock,
and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be
published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, notice that such money and shares of Common Stock remain
unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money and shares of Common Stock then remaining will be repaid or delivered to the Company.

 Section 4.05. Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence. 
 Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) At any
time the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted
securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issuable
upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) 

  
 28 













 
under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial owner of
such Notes or such Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A, as such rule may be amended from
time to time. 
 (b)    The Company shall file with the Trustee, within 15 days after the same are required to be filed
with the Commission (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act), copies of any documents or reports that the Company is required to file with the Commission pursuant to
Section 13 or 15(d) of the Exchange Act. 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. 
 (c)    Delivery of the reports, information and documents
described in subsection (b) above to the Trustee is for informational purposes only, and the Trustee’s receipt thereof shall not constitute actual or constructive knowledge or notice of any information contained, or determinable from
information contained, therein, including the Company’s compliance with any of its covenants under this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively rely on an Officers’ Certificate). The Trustee shall
not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with any of its covenants hereunder or to determine whether such reports, information or documents have been filed by the Company with the
Commission via the EDGAR system (or any successor system). 
 (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 immediately preceding (as a result of restrictions pursuant
to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal amount of the Notes
outstanding for each day during such period for which the Company’s failure to file has occurred and is continuing or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or
Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes. As used in this Section 4.06(d),
documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to
Section 13 or 15(d) of the Exchange Act. 
 (e)    If, and for so long as, the restrictive legend on the Notes
specified in Section 2.05(c) has not been removed, the Notes are assigned a restricted CUSIP or the Notes are not 

  
 29 













 
otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months
immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 375th day after the last date of original issuance of the Notes, the Company shall pay Additional Interest on the
Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes are assigned an unrestricted CUSIP and the Notes are
freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities
laws or the terms of this Indenture or the Notes. 
 (f)    Additional Interest will be payable in arrears on each
Interest Payment Date following accrual in the same manner as regular interest on the Notes. 
 (g)    The Additional
Interest that is payable in accordance with Section 4.06(d) or Section 4.06(e) shall be 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; provided, however, that in no event shall Additional Interest with respect to the Notes payable in accordance with Section 4.06(d) as a result of the Company’s failure to timely file any document or report that
the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form
8-K), together with any Additional Interest that may accrue at the Company’s election for failure to comply with its reporting obligations as set forth in 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. 

(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 Officers’ 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 Officers’ 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.

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, 2020) an Officers’ 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 in the previous 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 that is continuing, an Officers’ 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 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(h) or Section 6.01(i) with respect
to the Company), 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 (and the Trustee, at the written request of such Holders, shall) 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(h) or Section 6.01(i) with respect to the Company occurs and is continuing, 100% of the principal amount 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 at such time) and amounts due to the Trustee pursuant to Section 7.06, and if (1) rescission
would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on
Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such 

  
 33 













 
case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the
Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been
cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the
contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Redemption Price and the Fundamental Change Repurchase
Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 

Section 6.03. Additional Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the
Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall 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 (i) 0.25% per annum of the principal amount of the Notes outstanding for the first 180 days during which such Event of Default has occurred and is continuing, beginning on, and
including, the date on which such an Event of Default first occurs and (ii) 0.50% per annum of the principal amount of the Notes outstanding for each day during the next 185-day period during which such Event
of Default is continuing beginning on, and including, the 181st day after such an Event of Default first occurred. 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 366th 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 366th 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 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 365 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders, the Trustee and the Paying Agent of such election prior to the
beginning of such 365-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 shall Additional Interest payable at the Company’s election for failure to comply with its reporting obligations as set forth
in this Section 6.03, together with any Additional Interest that may accrue pursuant to Section 4.06(d) as a result of the Company’s failure to timely file any document or report that the Company is required to file with the


  
 34 













 
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), 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. For the avoidance
of doubt, any Additional Interest that accrues on a note pursuant to this Section 6.03 will be in addition to the stated interest that accrues on such Note and, subject to the preceding sentence, in addition to any Additional Interest that
accrues on such Note pursuant to Section 4.06(d) or 4.06(e). 
 Section 6.04. Payments of Notes on Default; Suit Therefor. If an
Event of Default described in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders, the whole amount then due and payable on the Notes for
principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee
under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid,
may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of
the Company or any other obligor upon the Notes, wherever situated. 
 In the event there shall be pending proceedings for the bankruptcy or
for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or
similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other
obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 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, 

  
 35 













 
to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee
under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason,
payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders may be entitled to receive in such proceedings, whether in liquidation or under
any plan of reorganization or arrangement or otherwise. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be
enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of
an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee (in any capacity), its agents and counsel, be for the ratable benefit of the
Holders. 
 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, and it shall not be necessary to make any Holders 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 (acting in any capacity) under Section 7.06; 

  
 36 













 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 and 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 and the Fundamental Change Repurchase Price and any cash due upon conversion) and interest without preference or
priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable,
the Redemption Price and the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and 

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

Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the
Redemption Price and the Fundamental Change 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 satisfactory to it in its reasonable
judgment against any loss, liability or expense to be incurred therein or thereby; 
 (d)    the Trustee has not
complied with such request within 60 days after its receipt of such notice, request and offer of such security or indemnity; and 

  
 37 













 (e)    no direction that, in the opinion of the Trustee, is inconsistent
with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to
Section 6.09, 
 it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and
Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to
obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all 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, each Holder shall have the right 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. 

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, by judicial
proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon
any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and
remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 

  
 38 













 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 (it being
understood that the Trustee does not have an affirmative duty to determine whether any direction is prejudicial to any Holder) or that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the
Notes at the time outstanding determined in accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued
and unpaid interest, if any, on, or the principal (including any Redemption Price and any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the
Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder
of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default
or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be
deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

Section 6.10. Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a
Responsible Officer has actual knowledge, deliver to all Holders notice of such Default, unless such Default 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 a committee of Responsible Officers of 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 

  
 39 













 
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.

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 satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction. 

(a)    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: 

(i)    this paragraph (a) does not limit the effect of paragraph (b) of this Section 7.01;

 (ii)    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 in a court of competent jurisdiction that the Trustee was grossly negligent in ascertaining the pertinent facts; 

(iii)    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. 

  
 40 













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

(c)    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. 
 (d)    The
Trustee shall not be liable in respect of any payment (as to the correctness of amount, calculation, 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. 
 (e)    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.

 (f)    In the absence of written investment direction from the Company, all cash received by the Trustee shall be
placed in a non-interest bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the
liquidation of any such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and
the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the Company. 

(g)    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. 

  
 41

risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 

Section 7.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 7.01: 

(a)    the Trustee may conclusively rely and shall be fully protected in acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, bond, note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties; 

(b)    any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an
Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company;

 (c)    the Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or
presented by the proper person and the Trustee may consult with counsel and require an Opinion of Counsel and any advice of such counsel or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or
omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 
 (d)    the Trustee
shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further 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)    before the Trustee acts or refrains from acting, it shall be entitled to receive an Officers’ Certificate and
an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith reliance on such Officers’ Certificate or Opinion of Counsel; 

(f)    the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by
or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney appointed by it with due care hereunder; and 

(g)    the permissive rights of the Trustee enumerated herein shall not be construed as duties. 

  
 42 













 In no event shall the Trustee be responsible or liable for any special, indirect, punitive
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. 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 and such notice references the Notes and this Indenture. 

Section 7.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s
certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of
the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. The Trustee shall
have no duty or obligation to monitor the Company’s compliance with the terms of this Indenture or to ascertain or inquire as to the observance, performance of any covenants, conditions or agreements of the issuer except as expressly set forth
in 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 Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would
have if it were not the Trustee, Paying Agent, Conversion Agent, Bid Solicitation Agent or Note Registrar. 
 Section 7.05. Monies
and Shares of Common Stock to Be Held in Trust. All monies and any shares of Common Stock received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received.
Money and shares of Common Stock held by the Trustee in trust hereunder need not be segregated from other funds or property except to the extent required by law. The Trustee shall be under no liability for interest on any money or shares of Common
Stock received by it hereunder except as may be agreed from time to time by the Company and the Trustee. 
 Section 7.06.
Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, 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). The Company also covenants to indemnify, defend and protect the Trustee (in its individual capacity and in any capacity under this Indenture and any other
document or transaction entered into in 

  
 43 













 
connection herewith) and its agents and any authenticating agent for, and to hold them harmless against, any and all loss, claim, damage, liability or expense (including reasonable
attorneys’ fees) incurred in connection with the acceptance or administration of this Indenture and/or the transactions contemplated under this Indenture or in any other capacity hereunder, including the costs and expenses of enforcing this
Indenture against the Company (including this Section 7.06) or defending themselves against any claim of liability in the premises and the Trustee shall have no liability or responsibility for any action or inaction on the part of any Paying
Agent, Note Registrar or successor trustee. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The
Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense
incurred by the Trustee through the Trustee’s own willful misconduct or gross negligence as finally adjudicated by a court of competent jurisdiction.    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 to pay principal and interest 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 of 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(h) or Section 6.01(i) occurs, the expenses and the compensation for the services are intended to constitute
expenses of administration under any bankruptcy, insolvency or similar laws. 
 Section 7.07. Intentionally Omitted. 

Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible 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 

  
 44 













 
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 60 days after the giving of such notice of
resignation to the Holders, the resigning Trustee (at the expense of the Company) 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, 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 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 upon 30 days’ prior notice 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. 

  
 45 













 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 deliver or cause to be delivered notice of the succession of such trustee hereunder to the Holders. If the
Company fails to deliver such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be delivered at the expense of the Company. 

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

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 

  
 46 













 
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 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 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 or (d) in the case of Notes
evidenced by a Global Note, by any electronic transmission or other message, whether or not in written format, that complies with the Depositary’s applicable procedures. Whenever the Company or the Trustee solicits the taking of any action by
the Holders, 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 

  
 47 













 
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 under this Indenture; 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. The sole registered holder of a Global Note shall be the
Depositary or its nominee. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge
the liability for monies payable or shares deliverable upon any such Note. 
 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 actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the
purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, 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 Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled
to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the evidence
to be included in the Notes the Holders of which have consented to such action may, by filing 

  
 48 













 
written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any
such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof,
irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof. 

ARTICLE 9

meeting and the establishment of any record date pursuant to Section 8.01, shall be delivered to Holders of such Notes. 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

 49 













 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 the place for such
meeting and may call such meeting to take any action authorized in Section 9.01, by delivering notice thereof as provided in Section 9.02. 

Section 9.04. Qualifications for Voting. To be entitled to vote at any meeting of Holders a Person shall (a) be a Holder of one or
more Notes on the record date pertaining to such meeting or (b) be a Person appointed by an instrument in writing as proxy by a Holder of one or more Notes on the record date pertaining to such meeting. The only Persons who shall be 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 regulations as
it may deem advisable for any meeting of Holders, in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and examination of 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 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. 
 Section 9.06. Voting. The vote
upon any resolution submitted to any meeting of Holders shall be by written ballot on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the outstanding aggregate principal amount of the Notes held or


  
 50 













 
represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who 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. 
 ARTICLE 10 

SUPPLEMENTAL INDENTURES 

Section 10.01. Supplemental Indentures Without Consent of Holders. The Company 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 one or more of the following purposes: 

(a) to cure any ambiguity, omission, defect or inconsistency;

(c) to add guarantees with respect to the Notes; 

(d) to secure the Notes; 
 (e)
to add to the covenants or Events of Default of the Company for the benefit of the Holders or surrender any right or power conferred upon the Company; 

(f) to make any change that does not adversely affect the rights of any Holder; 

  
 51 













 (g) in connection with any Merger Event, to provide that the Notes are convertible into
Reference Property, subject to the provisions of Section 14.02, and make such related changes to the terms of the Notes to the extent expressly required by Section 14.07; or 

(h) to conform the provisions of this Indenture or the Notes to the “Description of Notes” section of the Offering Memorandum; 

(i) to amend this Indenture or the Notes to comply with the rules of any applicable securities depositary, including the Depositary, so long
as such amendment does not adversely affect the rights of any Holder; 
 (j) to irrevocably elect a Settlement Method or a Specified Dollar
Amount, or eliminate the Company’s right to elect a Settlement Method; provided, however, that no such election or elimination will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note in
accordance with Section 14.02; 
 (k) to provide for the issuance of additional Notes; or 

(l) to increase the Conversion Rate as provided in this Indenture. 

Upon the written request of the Company, and subject to Section 10.05, the Trustee shall join with the Company in the execution of any
such supplemental indenture, 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
offer for, Notes), the Company 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 to or changing in any manner or
eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that, without the consent of each Holder of an outstanding Note affected, no
such supplemental indenture shall: 
 (a) reduce the amount of Notes whose Holders must consent to an amendment; 

(b) reduce the rate of or extend the stated time for payment of interest on any Note; 

(c) reduce the principal of or extend the Maturity Date of any Note; 

  
 52 













 (d) make any change that adversely affects the conversion rights of any Notes;

the Company’s obligation to make such payments, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise; 

(f) make any Note payable in a currency, or at a place of payment, other than that stated in the Note; 

(g) change the ranking of the Notes; or 

(h) make any change in this Article 10 that requires each Holder’s consent or in the waiver provisions in Section 6.02 or
Section 6.09. 
 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as
aforesaid and subject to Section 10.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture
or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

Holders do not need under this Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be
sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall deliver to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such
notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 

Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of
this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the
Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms
and conditions of this Indenture for any and all purposes. 
 Section 10.04. Notation on Notes. Notes authenticated and
delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at
the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or 

  
 53 













 
an authenticating agent duly appointed by the Trustee pursuant to Section 17.11) upon receipt of an Officers’ Certificate, an Opinion of Counsel, and a Company Order and delivered in
exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 
 Section 10.05. Evidence of Compliance of
Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by Section 17.05, the Trustee shall receive an Officers’ 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 any Opinion of Counsel shall state that the supplemental indenture 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. 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, unless: 
 (a) the resulting,
surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, 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; and 

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this
Indenture. 
 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 Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance,
transfer or lease and upon the assumption by the Successor Company as provided above, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, 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. 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 

  
 54 













 
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. 
 ARTICLE 12 

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

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 one or more of the
conditions described in Section 14.01(b), at any time prior to January 1, 2025 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 January 1, 2025 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, based on an initial conversion rate of 42.6203 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 January 1, 2025, 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 five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by
a Holder 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 pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Bid Solicitation Agent (if other than the Company) shall have
no obligation to solicit secondary market bid quotations, in accordance with the definition of Trading Price, in respect of the Trading Price per $1,000 principal amount of Notes unless the Company has requested such solicitation in writing and
provided to the Bid Solicitation Agent the name and contact information of the three nationally recognized securities dealers selected by the Company to provide secondary market bid quotations, 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 one or more Holders in the aggregate of at least $5,000,000 aggregate
principal amount of Notes provides the Company with reasonable evidence that the Trading Price 

  
 56 













 
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. At such time, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to so solicit secondary market bid quotations in respect of (and provide such names and contact information), 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 obtain bids as provided in the preceding sentence and provide to the Bid Solicitation Agent the name and contact information of the three nationally recognized securities dealers selected by the Company to provide such secondary market bid
quotations, or if the Company instructs the Bid Solicitation Agent to obtain bids and provides the names and contact information to the Bid Solicitation Agent, and the Bid Solicitation Agent fails to carry out such instruction, 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 in writing 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 in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee). Neither the Trustee nor any Bid
Solicitation Agent (other than the Company) shall have any liability or responsibility for any Trading Price or related information or the accuracy thereof. 

(ii) If, prior to January 1, 2025, 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
shareholder rights plan, so long as such rights have not separated from the Common Stock) entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the 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 
 (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 shareholder rights plan, so long as such rights have not separated from the Common Stock), which distribution has a per share value, as reasonably determined by the Board of
Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement for such distribution, 

then, in either case, the Company shall notify in writing all Holders, the Trustee and the Conversion Agent (if other than the Trustee) (x) at least 55
Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution, or (y) at least 10 Scheduled Trading Days 

  
 57 













 
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 in Section 14.02 or any other provision of this Indenture, the Company will 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 Record Date for such issuance or distribution (or the date of the Company’s announcement that such issuance or distribution will not
take place) using Physical Settlement and the Company will so notify the Holders of such required Settlement Method 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 may not exercise the conversion right set forth in this Section 14.01(b)(ii) if they 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 14.01(b)(ii) 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. 
 (iii) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental
Change occurs prior to January 1, 2025, 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 consolidation, merger, binding share exchange,
or transfer or lease of all or substantially all of its assets that occurs prior to January 1, 2025, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, other than a merger effected solely
to change the Company’s jurisdiction of incorporation that does not otherwise constitute a Fundamental Change or a Make-Whole Fundamental Change, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or
after the effective date of the transaction until 35 Trading Days after such effective date or, if such transaction 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 preceding the related Fundamental Change Repurchase Date. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in
writing of the effective date of any such transaction no later than the second Business Day following such effective date. 

(iv) Prior to January 1, 2025, 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 September 30, 2020 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive)
during the period of 30 consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day.


  
 58 













 
The Company shall determine at the beginning of each calendar quarter commencing after September 30, 2020 whether the Notes may be surrendered for conversion in accordance with this clause
(iv) and shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing if the Notes become convertible in accordance with this clause (iv); provided that failure to give such notice will not be
considered a Default or form the basis for an Event of Default for any purpose under this Indenture. 
 (v) If the Company
issues a Redemption Notice with respect to any or all of the Notes pursuant to Article 16 prior to January 1, 2025, then a Holder may surrender all or any portion of its Called Notes for conversion at any time prior to the close of business on
the second Scheduled Trading Day prior to the Redemption Date, even if the Called Notes are not otherwise convertible at such time. After that time, the right to convert such Called Notes shall expire, unless the Company defaults in the payment of
the Redemption Price, in which case a Holder may convert its Called Notes until the Redemption Price has been paid or duly provided for. If the Company elects to redeem fewer than all of the outstanding Notes for redemption pursuant to Article 16,
and the Holder of any Note (or any owner of a beneficial interest in any Global Note) is reasonably not able to determine, prior to the close of business on the 54th Scheduled Trading Day immediately before the relevant Redemption Date (or if, as
permitted by Section 16.02(a), the Company delivers a Redemption Notice not less than 10 nor more than 60 Scheduled Trading Days prior to the related Redemption Date, then prior to close of business on the 9th Scheduled Trading Day immediately
before the relevant Redemption Date), whether such Note or beneficial interest, as applicable, is to be redeemed pursuant to such redemption, then such Holder or owner, as applicable, will be entitled to convert such Note or beneficial interest, as
applicable, at any time before the close of business on the second Scheduled Trading Day prior to such Redemption Date, unless the Company defaults in the payment of the Redemption Price, in which case such Holder or owner, as applicable, will be
entitled to convert such Note or beneficial interest, as applicable, until the Redemption Price has been paid or duly provided for, and each such conversion will be deemed to be of a Note called for redemption, and such Note or beneficial interest
will be deemed called for redemption solely for the purposes of such conversion (“Deemed Redemption”). If a Holder elects to convert Called Notes during the related Redemption Period, the Company will, under certain circumstances,
increase the Conversion Rate for such Called Notes pursuant to Section 14.03. Accordingly, if the Company elects to redeem fewer than all of the outstanding Notes pursuant to Article 16, Holders of the Notes that are not Called Notes will not
be entitled to convert such Notes pursuant to this Section 14.01(b)(v) and will not be entitled to an increase in the Conversion Rate on account of the Redemption Notice, even if such Notes are otherwise convertible pursuant to any other
provision of this Section 14.01(b) and are converted during the related Redemption Period. The Trustee shall not be obligated to determine whether any beneficial owner’s Notes are subject to Deemed Redemption. 

Section 14.02. Conversion Procedure; Settlement Upon Conversion. 

  
 59 













 (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 (x) conversions for which the relevant Conversion Date occurs after the Company’s
issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date shall be settled using the same Settlement Method, and (y) all conversions for which the relevant Conversion Date occurs on or after
January 1, 2025 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 Redemption Notice with respect to the Notes but prior to the related Redemption Date, and any conversions for which the relevant Conversion Date occurs on or after
January 1, 2025, 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 one of the periods described in the third immediately
succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the
Company shall deliver such Settlement Notice to converting Holders, the Trustee and the Conversion Agent (if other than the Trustee) 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 Redemption Notice with respect to the Notes and prior to the related Redemption Date, in such Redemption Notice or (y) on or
after January 1, 2025, no later than January 1, 2025). 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 does not elect a Settlement Method prior to the deadline set forth in the second immediately preceding sentence, the Company shall be deemed to have elected the Default
Settlement Method in respect of its Conversion Obligation. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not timely notify the converting Holder of the applicable
Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of Notes. For the avoidance of doubt, the Company’s failure to timely elect a Settlement Method or specify the
applicable Specified Dollar Amount shall not constitute a Default under this Indenture. 

  
 60 













 (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 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 50 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, to the converting Holder 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 50 consecutive Trading Days during the related Observation Period. 
 (v) The Company may,
from time to time, change the Default Settlement Method by sending written notice of the new Default Settlement Method to all Holders, the Trustee and the Conversion Agent (if other than the Trustee). In addition, the Company may, by sending written
notice to all Holders, irrevocably fix the Settlement Method to any Settlement Method that the Company is then permitted to elect, which Settlement Method shall apply to all conversions of Notes with a Conversion Date that is after the date the
Company sends such written notice. Notwithstanding anything to the contrary in this Indenture, no such change in the Default Settlement Method or irrevocable Settlement Method election will affect any Settlement Method theretofore elected (or deemed
to be elected) with respect to any Note pursuant to this Section 14.02. Concurrently with providing notice to all Holders of a change in the Default Settlement Method or an election to irrevocably fix the Settlement Method, the Company shall
promptly issue a report on Form 8-K or press release announcing that the Company has made such change to the Default Settlement Method or elected to irrevocably fix the Settlement Method, as the case may be.
For the avoidance of doubt, such an irrevocable Settlement Method election, if made, shall be effective without the need to amend this Indenture or the Notes, including pursuant to Section 10.01(j). However, the Company may nonetheless choose
to execute such an amendment at the Company’s option. 

  
 61 













 (vi)    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 and in any event within one Business Day 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 send such determination and the
calculation thereof in reasonable detail or in such details as requested by the Depositary to the Trustee and the Conversion Agent (if other than the Trustee). 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 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 the 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 or if a conversion is processed outside of the Depositary (1) complete, manually sign and deliver an irrevocable
notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to
be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such
Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents, (4) if
required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (5) provide or cause to be provided to the Trustee and Conversion Agent (if other
than the Trustee) all information necessary to allow the Trustee or Conversion Agent (if other than the Trustee) to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under
Internal Revenue Code Section 6045. The Trustee and Conversion Agent may rely on information provided to it and shall have no responsibility whatsoever to verify or ensure the accuracy of such information. The Trustee (and if different, the
Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date (or as soon as practicable thereafter) 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. 

Notes may be surrendered for conversion only after the open of business and before the close of business on a Business Day. 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. 

  
 62 













 (c)    A Note shall be deemed to have been converted immediately prior
to the close of business on the Business Day (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. 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
(provided that, with respect to any conversion following the Regular Record Date immediately preceding the Maturity Date where Physical Settlement applies, the Company will settle any such conversion on the Maturity Date or, if the Maturity
Date is not a Business Day, the next Business Day, and the Conversion Date will be deemed to be such date), 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 a converting Holder, the Company shall issue or cause to be issued, and deliver (if applicable) to the converting Holder, or such Holder’s nominee or nominees, the full number of shares of Common
Stock to which such Holder shall be entitled, in book-entry format through the Depositary, in satisfaction of the Company’s Conversion Obligation. 

(d)    In case any Physical 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 Physical Note so surrendered a new Physical Note or Physical Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the
surrendered Physical 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 Physical Notes issued upon such conversion being different from the name of the Holder of the old Physical Notes
surrendered for such conversion. 
 (e)    If a Holder submits a Note for conversion, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case
the Holder shall pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax
that is due by such Holder in accordance with the immediately preceding sentence. 
 (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 cause a reduction on such Global Note 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. 

  
 63 













 (h)    Upon conversion, a Holder shall not receive any separate cash
payment for accrued and unpaid interest, if any, except as set forth below, and the Company will not adjust the Conversion Rate for any accrued and unpaid interest on the Notes. 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 Redemption Date that is after a Regular Record Date and on or prior to the second Business Day immediately following
the corresponding Interest Payment Date; (3) 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; 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 Holders of record at the close of business on the Regular
Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date in cash regardless of whether their Notes have been converted following such Regular Record Date. 

(i)    The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be deemed to be the
shareholder of record as of the close of business on the relevant Conversion Date (in the case of Physical Settlement) or the last Trading Day of the relevant Observation Period (in the case of Combination Settlement), as the case may be. Upon a
conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion. 
 (j)    The
Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant
Conversion Date or, if such Conversion Date is not a Trading Day, the immediately preceding Trading Day (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 (or is deemed to have elected) Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the
basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash. If a 

  
 64 













 
Holder converts more than one (1) Note on a single Conversion Date, then cash in lieu of fractional shares due in respect of such conversion will (in the case of any Global Note, to the
extent permitted by, and practicable under, the Depositary’s applicable procedures) be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder. 

Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes
or Called Notes During a Redemption Period. (a) If (x) the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or
(y) the Company gives a Redemption Notice with respect to any or all of the Notes in accordance with Section 16.01 and a Holder elects to convert its Called Notes during the related Redemption Period, as the case may be, 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 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 Redemption Notice if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the date of the
Redemption Notice until the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date. For the avoidance of doubt, if the Company elects to redeem fewer than all of the outstanding Notes pursuant to Article 16,
Holders of the Notes that are not Called Notes will not be entitled to convert such Notes pursuant to Section 14.01(b)(v) and will not be entitled to an increase in the Conversion Rate on account of the Redemption Notice, even if such Notes are
otherwise convertible pursuant to Section 14.01(b)(i)-(iv) and are converted during the related Redemption Period. 

(b)    Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to
Section 14.01(b)(iii) or upon surrender of Called Notes during a Redemption Period, 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 

  
 65 













 
second Business Day following the Conversion Date. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole
Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

(c)    The number of Additional Shares, if any, by which the Conversion Rate shall be increased for conversions in
connection with a Make-Whole Fundamental Change or, with respect to conversions of Called Notes, during the related Redemption Period 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 Redemption Notice, as the case may be, (in each case, the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share of the Common Stock
in the Make-Whole Fundamental Change or with respect to the Optional Redemption, as the case may be. 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 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 Redemption Notice, 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. If a conversion of Called Notes during a Redemption Period would also be deemed to be in connection with a Make-Whole
Fundamental Change, a Holder of any such Notes to be converted will be entitled to a single increase to the Conversion Rate with respect to the first to occur of the Effective Date of the Notice of Redemption or the Make-Whole Fundamental Change, as
applicable, and the later event shall be deemed not to have occurred for purposes of this Section 14.03. 

(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. 

  
 66 













 (e)    The following table sets forth the number of Additional Shares of
Common Stock 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 Price and Effective Date may not be set forth in the table above, in which case: 

(i)    if the Stock Price is between two Stock Prices in the table above or the Effective Date is between
two Effective Dates in the table, the number of Additional Shares by which the Conversion Rate will be increased 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 or 366-day year, as applicable; 

(ii)    if the Stock Price is greater than $200.00 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 $17.38 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 57.5373 shares of Common Stock, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 
 (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 Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

  
 67 













 (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: 

 

			
	CR’ = CR0 ×	 	 OS’

	 	OS0 

  

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

 Any adjustment made under this Section 14.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the
type described in this Section 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b)    If the
Company issues to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a shareholder 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 the 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: 
  

			
	CR’ = CR0 ×	 	 OS0 + X

	 	OS0 + Y


  
 68 













 where, 
  

					
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR’	 	=	 	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	 	=	 	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	 	=	 	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	 	=	 	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 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 the Common Stock are not delivered after the expiration of
such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only
the number of shares of Common Stock actually delivered. If 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. 

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 of the Common Stock to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and
including, the Trading Day immediately preceding the 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 as to which an adjustment is provided for
pursuant to Section 14.04(a) or Section 14.04(b), as applicable, (ii) rights issued under a shareholder rights plan (except as set forth in Section 14.11), (iii) dividends or distributions paid


  
 69 













 
exclusively in cash as to which the provisions set forth in Section 14.04(d) shall apply, (iv) distributions of Reference Property issued in exchange for, or upon conversion of, the
Common Stock in a Merger Event; 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: 

 

			
	 CR’ = CR0 ×
	 	
          SP0        

	 	     SP0 – FMV


  

					
	where,
			
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR’	 	=	 	the Conversion Rate in effect immediately after the open of business on 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 by the Company in good faith) of the Distributed Property distributed with respect to each outstanding share of the Common Stock on the Ex-Dividend Date
for such distribution.

 Any increase made under the portion of this Section 14.04(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in
respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder
owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for 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: 
  

			
	
CR’ = CR0 ×
	  	 FMV0 + MP0 

	  	MP0 


  
 70 














					
	where,
			
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR’	 	=	 	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	 	=	 	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last
Reported Sale Price as 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 at the close of business 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 to
“10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such
Spin-Off to, and including, 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 to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have
elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, and including, such Trading Day in determining the Conversion Rate as of such Trading Day. 

For purposes of this Section 14.04(c) (and subject in all respect to Section 14.11), rights, options or warrants distributed by the
Company to all holders of 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 shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the
Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event,
whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.04(c). If any such right, option or warrant,
including any such existing rights, options or warrants 

  
 71 













 
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. 

(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: 
  

			
	CR’ = CR0 ×	  	 SP0 

	  	SP0 – C

  

					
	where,
			
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR’	 	=	 	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	 	=	 	the 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


  
 72 













 
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 shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock
equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. 

(e)    If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common
Stock (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 the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10
consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall
be increased based on the following formula: 
  

			
	
CR’ = CR0 ×

 
	  	AC + (SP’ × OS’)
	  	OS0 × SP’

  

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


  
 73 













 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 to “10” or
“10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date that such tender or exchange offer expires to, and including,
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 to “10” or “10th” in the preceding paragraph
shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the expiration date of such tender or exchange offer to, and including, 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 shares of the
Common Stock pursuant to any such tender offer or exchange offer described in this Section 14.04(e), but the Company or such Subsidiary is permanently prevented by applicable law from consummating any such purchases, or all such purchases are
rescinded, then the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that have been consummated. 

(f)    Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if: 

(i)    a Conversion Rate adjustment for any event pursuant to Section 14.04 becomes effective on any Ex-Dividend Date; 
 (ii)    a Note is to be converted and Physical
Settlement or Combination Settlement applies to such conversion; 
 (iii)    the Conversion Date for such
conversion (in the case of Physical Settlement) or any Trading Day in the Observation Period for such conversion (in the case of Combination Settlement) occurs on or after such Ex-Dividend date and on or
before the related Record Date; 

  
 74 













 (iv)    the consideration due upon such conversion (in
the case of Physical Settlement) or due with respect to such Trading Day (in the case of Combination Settlement) includes any whole shares of Common Stock; and 

(v)    the Holder of such Note would be treated, on such Record Date, as the record holder of such shares
of Common Stock based on a Conversion Rate that is adjusted for such event on such basis, 
 then such Conversion Rate adjustment will not be given effect
for such conversion (in the case of Physical Settlement) or for such Trading Day (in the case of Combination Settlement). Instead, such Holder shall be treated as if such Holder were, as of the Record Date, the record owner of such shares of Common
Stock on an unadjusted basis and will participate in such event. 
 (g)    Notwithstanding this Section 14.04 or
any other provision in this Indenture or the Notes, if: 
 (i)    a Note is to be converted and, as of
the Conversion Date for such conversion (in the case of Physical Settlement) or as of any Trading Day in the Observation Period for such conversion (in the case of Combination Settlement), the Record Date or effective date for any event that
requires an adjustment to the Conversion Rate pursuant to Section 14.04 has occurred but an adjustment to the Conversion Rate for such event has not yet become effective; 

(ii)    the consideration due upon such conversion (in the case of Physical Settlement) or due in respect
of such Trading Day (in the case of Combination Settlement) consists of any whole shares of Common Stock; and 

(iii)    such shares are not entitled to participate in such event (because they were not held on the
related Record Date or otherwise), 
 then, solely for purposes of such conversion, the Company will, without duplication, give effect to such adjustment on
such Conversion Date (in the case of Physical Settlement) or such Trading Day (in the case of Combination Settlement). In such case, if the date the Company is otherwise required to deliver the consideration due upon such conversion is before the
first date on which the amount of such adjustment can be determined, then the Company will delay the settlement of such conversion until the second Business Day after such first date. 

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

(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 

  
 75 













 
to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best
interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company may (but is not required to) increase the Conversion Rate
to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the
Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note a notice of the increase 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 set forth in this
Article 14, 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 Common Stock at a price below the Conversion Price or otherwise, except as set
forth in Section 14.04(b) or Section 14.04(c); 
 (ii)    on account of share repurchases that
are not tender offers or exchange offers referred to in Section 14.04(e), including structured or derivative transactions or pursuant to a share repurchase program approved by the Board of Directors; 

(iii)    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; 

(iv)    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; 

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

(vi)    for a third party tender offer or exchange offer by any party other than a tender offer or exchange
offer by one or more of the Subsidiaries of the Company as described in Section 14.04(e); 

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

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

  
 76 













 (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. 

(l)    If an adjustment to the Conversion Rate otherwise required by this Section 14.04 would result in a change of
less than 1% to the Conversion Rate, then, notwithstanding the foregoing, the Company may, at its election, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest to
occur of the following: (i) when all such deferred adjustments would result in an aggregate change of at least 1% to the Conversion Rate; (ii) the Conversion Date of, or any Trading Day of an Observation Period for, any Note;
(iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs; and (iv) January 1, 2025. 

(m)    Whenever the Conversion Rate is adjusted as herein provided, the Company shall as soon as reasonably practicable
file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment, provided
that failure to deliver such Officers’ Certificate will not constitute a Default for any purpose under this Indenture. Unless and until a Responsible Officer of the Trustee (and the Conversion Agent if not the Trustee) shall have received such
Officers’ Certificate, the Trustee (and the Conversion Agent if not 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, with a copy to the Trustee and the Conversion Agent (if other than the Trustee); provided that failure to give such notice will not be
considered a Default or form the basis for an Event of Default for any purpose under this Indenture. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

(n)    For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not
include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock
issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 Section 14.05. Adjustments of
Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including, without
limitation, an Observation Period and the period, if any, for determining the Stock Price for purposes of a Make-Whole Fundamental Change or Optional Redemption), the Board of Directors shall make appropriate adjustments to each to account for any
adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the
event occurs, at any time during the period when the Last Reported Sale Prices, the Daily 

  
 77 













 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 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). 

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 a change to par
value, or from par value to no par value, or changes resulting from a subdivision or combination), 

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

(iii)    any sale, lease or other transfer to a third party of the consolidated assets of the Company and
the Company’s Subsidiaries substantially as an entirety or 
 (iv)    any statutory share exchange,

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

  
 78 













 
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, (III) the Daily VWAP shall be
calculated (in a manner determined by the Company in good faith) based on the value of a unit of Reference Property and (IV) the conditions to conversion described in Section 14.01(b)(i), Section 14.01(b)(ii),
Section 14.01(b)(iii), Section 14.01(b)(iv) and Section 14.01(b)(v) will be determined as if each reference to a share of Common Stock were instead a reference to 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 shareholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be the weighted average of the types and amounts of consideration
actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common
Stock. If the holders 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 in writing Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that
shall be as nearly equivalent as possible to the adjustments provided for in this Article 14 in a manner that the Company deems appropriate in its reasonable discretion to preserve the economic interests of Holders. 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 Company or the successor or purchasing corporation, as the case may be, in such
Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders as the Company deems appropriate in its reasonable discretion 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 Officers’ 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


  
 79 













 
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 other Reference Property, if applicable) or a combination of cash and shares of Common Stock
(or other Reference Property, if applicable), 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 liens and charges with respect to the issue thereof. 

(b)    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 commercially reasonable efforts to list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon
conversion of the Notes. 
 Section 14.09. Responsibility of Trustee and the Conversion Agent. 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 

  
 80 













 
accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officers’
Certificate (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 reasonably promptly after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). Neither the Trustee, nor the Conversion Agent shall have any obligation to independently determine
or verify if any Fundamental Change, Make-Whole Fundamental Change, Trigger Event, or any other event has occurred or notify the Holders of any such event. Neither the Trustee, nor the Conversion Agent shall have the responsibility for any act or
omission of any designated financial institution described in Section 14.12. 
 Section 14.10. Intentionally Omitted. 

Section 14.11. Shareholder Rights Plans. If the Company has a shareholder rights plan in effect upon conversion of the Notes into
shares of Common Stock, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear
such legends, if any, in each case as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time. 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 shareholder 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 second 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, a designated financial institution must agree in writing to timely pay or deliver, as the case may be, in exchange for such Notes, cash, shares of Common Stock, or a combination of
cash and shares of the Common Stock, at the Company’s election, that would otherwise be due upon conversion pursuant to Section 14.02 or such other amount agreed to by the Holder and such designated financial institution (the
“Conversion Consideration”). If the Company makes an Exchange Election, the Company shall, by the close of business on the Trading Day immediately following the relevant Conversion Date, notify in writing the Trustee, the Conversion
Agent (if other than the Trustee) and the Holder surrendering 

  
 81 













 
its Notes for conversion that the Company has made the Exchange Election, and the Company shall notify such designated financial institution of the Settlement Method election and relevant
deadline for delivery of the consideration due upon conversion and the type of Conversion Consideration to be paid and/or delivered, as the case may be. The Company, the Holder surrendering the Notes for conversion, the designated financial
institution and the Conversion Agent shall cooperate to cause such Notes to be delivered to the designated financial institution and the Conversion Agent shall be entitled to conclusively rely upon the Company’s instruction in connection with
effecting any Exchange Election and shall have no liability for such Exchange Election. 
 (b)    Any Notes delivered to
a designated financial institution shall remain outstanding, subject to applicable procedures of the Depositary. If such designated financial institution agrees to accept any Notes for exchange but does not timely pay and/or deliver, as the case may
be, the related Conversion Consideration, or if such designated financial institution does not accept the Notes for exchange, the Company shall notify the Trustee, Conversion Agent and the Holder surrendering their Notes for conversion and the
Company shall pay and/or deliver, as the case may be, the relevant Conversion Consideration, as, and at the time, required pursuant to this Indenture as if the Company had not made the Exchange Election. 

(c)    The Company’s designation of any financial institutions to which the Notes may be submitted for exchange does
not require such financial institutions to accept any Notes. 
 ARTICLE 15 

REPURCHASE OF NOTES AT OPTION OF
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 of the principal thereof that is equal to minimum denominations of $1,000 or an
integral multiple of $1,000 in excess thereof, 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. 

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

  
 82 













 (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 

(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) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with
the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change 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 a minimum
denomination of $1,000 or an integral multiple in excess 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 Trustee and the Paying Agent in accordance with Section 15.03 in the
case of Physical Notes, or through the applicable procedures of the Depositary, in the case of Global Notes. 
 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 effective date of a Fundamental Change, the Company shall provide to
all Holders and the Trustee, Conversion Agent (if other than the Trustee) and the Paying Agent (in the case of a Paying Agent other than the Trustee) a written notice (the “Fundamental Change Company Notice”) of the occurrence of
the Fundamental Change and of the repurchase right at the option of the Holders arising as a result 

  
 83 













 
thereof. In the case of Physical Notes, such notice shall be delivered 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. Simultaneously with providing such notice, the Company shall publish the information set forth in the Fundamental Change Company Notice on the Company’s website, through a press release or through such other public
medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 

(i)    the events causing the Fundamental Change; 

(ii)    the effective date of the Fundamental Change; 

(iii)    the last date on which a Holder may exercise the repurchase right pursuant to this Article 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 as a result of such
Fundamental Change; 
 (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. 

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, 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 

  
 84 













 
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. 
 (e)    Notwithstanding anything to the contrary in this
Section 15.02, the Company shall not be required to repurchase, or make an offer to repurchase, Notes upon a Fundamental Change: 

(i)    if a third party makes an offer to repurchase the Notes upon a Fundamental Change 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 in Section 15.02 of this Indenture 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 in Section 15.02 of this Indenture; or 

(ii)    pursuant to clause (b) of the definition thereof if (x) such Fundamental Change results
in the Notes becoming convertible (pursuant to the provisions described in 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 as
part of the Fundamental Change Repurchase Price) irrespective of the Settlement Method the Company elects and (y) 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 requirements set forth in clause (x) and (y) of this Section 15.02(e)(ii), the “Adequate Cash Conversion Provisions”). 

Section 15.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be
withdrawn by Holders of Physical Notes (in whole or in part) by means of a written notice of withdrawal delivered to the Trustee and the Corporate Trust Office of the Paying Agent in accordance with this Section 15.03 at any time prior to the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 

(i)    the principal amount of the Notes with respect to which such notice of withdrawal is being
submitted, which portion must be in principal amounts of $1,000 or a 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 

  
 85 













 (iii)    the principal amount, if any, of such Note that
remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or a multiple thereof; 

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 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 payable to the Holder on the relevant Regular Record Date in accordance with Section 15.02(a)). 

(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: 

  
 86 













 (a)    comply with the provisions of Rule
13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable; 

(b)    file a Schedule TO or any 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 Company’s obligations to offer to repurchase and to repurchase Notes
pursuant to this Article 15 conflict with any law or regulation that is applicable to the Company, the Company’s compliance with such law or regulation will not be considered to be a default of such obligations. 

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 at
its option prior to July 5, 2023. On or after July 5, 2023, the Company may redeem (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) during any 30 consecutive Trading Day period (including the last Trading Day of such period) ending on, and including, the
Trading Day immediately preceding the date on which the Company provides the Redemption Notice in accordance with Section 16.01. Notwithstanding the foregoing, if the Redemption Date specified for a redemption under this Article 16 is on or
after January 1, 2025, the Optional Redemption must be for all, and not less than all, of the then outstanding Notes. 

Section 16.02.    Notice of Optional Redemption; Selection of Notes. (a) In case the Company exercises
its Optional Redemption right to redeem all or, as the case may be, any part of the Notes pursuant to Section 16.01, it shall fix a date for redemption (each, a “Redemption Date”) and it or, at its written request received by
the Trustee not less than at least 5 Business Days before the date of giving the Redemption Notice pursuant to this Section 16.02 (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the
expense of the Company, shall deliver or cause to be delivered a notice of such Optional Redemption (a “Redemption Notice”) not less than 55 nor more than 70 Scheduled Trading Days prior to the Redemption Date (provided that
if the Company has elected Physical Settlement in respect of all conversions for which the relevant Conversion Date occurs on or after the date on which the Company gives such Redemption Notice and prior to the close of business on the second
Scheduled Trading Day immediately preceding the related Redemption Date, then the Company shall provide not less than 10 nor more than 60 Scheduled Trading 

  
 87 













 
Days’ notice prior to the Redemption Date) to each Holder of Notes so to be redeemed as a whole or in part; provided, however, that, if the Company shall give such notice, it
shall also give written notice of the Redemption Date to the Trustee and the Paying Agent (if other than the Trustee). The Redemption Date must be a Business Day. 

(b)    The Redemption Notice, if delivered in the manner herein provided, shall be conclusively presumed to have been duly
given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the
validity of the proceedings for the redemption of any other Note. 
 (c)    Each Redemption Notice shall specify: 

(i)    the Redemption Date; 

(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; 

(iv)    the place or places where such Notes are to be surrendered for payment of the Redemption Price;

 (v)    that Holders of Called Notes may surrender their Notes for conversion at any time prior to the
close of business on the second Scheduled Trading Day immediately preceding the Redemption Date; 

(vi)    the procedures a converting Holder must follow to convert its Notes and the Settlement Method and
Specified Dollar Amount, if applicable; 
 (vii)    the Conversion Rate and, if applicable, the number of
Additional Shares added to the Conversion Rate in accordance with Section 14.03; 
 (viii)    the
CUSIP, ISIN or other similar numbers, if any, assigned to such Notes; and 
 (ix)    in case any Physical
Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed and on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be
issued. 
 A Redemption Notice shall be irrevocable. 

(d)    If fewer than all of the outstanding Notes are to be redeemed, and the Notes to be redeemed are Global Notes, the
Notes to be redeemed will be selected by the Depositary in 

  
 88 













 
accordance with the applicable procedures of the Depositary. If fewer than all of the outstanding Notes are to be redeemed, and the Notes to be redeemed are not Global Notes then held by the
Depositary, the Trustee shall select the Notes to be redeemed (in principal amounts of $1,000 or multiples thereof) on a pro rata basis, or by another method the Trustee considers to be fair and appropriate. 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 Redemption Notice has been given in respect of the Notes in
accordance with Section 16.01, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place
or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price. 

(b)    Prior to 11:00 a.m. Eastern Time on the Redemption Date, the Company shall 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).

 Section 17.11. Authenticating Agent. The Trustee may appoint an authenticating
agent that shall be authorized to act on its behalf and subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under
Section 2.04, Section 2.05, Section 2.06, Section 2.07, Section 10.04 and Section 15.04 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those
Sections to authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a
certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at
all times be a Person eligible to serve as trustee hereunder pursuant to Section 7.08. 
 Any corporation or other entity into which
any authenticating agent may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any
corporation or other entity succeeding to the corporate trust business of any authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this
Section 17.11, without the execution or filing of any paper or any further act on the part of the parties hereto or the authenticating agent or such successor corporation or other entity. 

Any authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at
any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice of such appointment to the Company and shall deliver notice of such
appointment to all Holders. 
 The Company agrees to pay to the authenticating agent from time to time reasonable compensation for its
services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 
 The
provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and this Section 17.11 shall be applicable to any authenticating agent. 

If an authenticating agent is appointed pursuant to this Section 17.11, the Notes may have endorsed thereon, in addition to the
Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 

                          
                      , 
 as Authenticating
Agent, certifies that this is one of the Notes described in the within-named Indenture.

forward the Company’s calculations to any Holder upon the request of that Holder at the sole cost and expense of the Company. 

Section 17.17. 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, record and update certain information that identifies each person or legal entity that establishes

 [FORM OF REVERSE OF NOTE] 

CryoLife, Inc. 
 4.250% Convertible
Senior Note due 2025 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 4.250% Convertible Senior
Notes due 2025 (the “Notes”), initially issued in an aggregate principal amount of $100,000,000 (as may be increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Initial Purchaser
pursuant to the exercise of its option to purchase additional Notes as set forth in the Purchase Agreement) all issued or to be issued under and pursuant to an Indenture dated as of June 23, 2020 (the “Indenture”), between the
Company and U.S. Bank National Association, a national banking association, as trustee (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. 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 the event of any inconsistency between this Note and the Indenture, the terms of the Indenture shall govern. 

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, the Redemption Price on any Redemption Date 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, and in
certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the
terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the
Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 

  
 A-7 













 Each Holder shall have the right 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, this Note at the place,
at the respective times, at the rate and in the lawful money or shares of Common Stock, as the case may be, herein prescribed. 
 The Notes
are issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples of $1,000 in excess thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and
subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with
payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the
old Notes surrendered for such exchange. 
 The Notes shall be redeemable at the Company’s option on or after July 5, 2023 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 exercised in the manner specified in the Indenture, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in
minimum principal amounts of $1,000 or integral multiples of $1,000 in excess 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 of the principal amount thereof that is $1,000 or an integral
multiple of $1,000 in excess thereof, into, at the Company’s election, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, based on the Conversion Rate specified in the Indenture, as adjusted from
time to time as provided in the Indenture.
