Securities Act. 
 Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms may,
upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of
shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.05(c). 
 Notwithstanding any other
provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated
form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the
Depositary and only to the extent otherwise permitted by this Section 2.05(c). 

  
 18 








 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 the Notes requests that its Notes be issued as Physical Notes, the Company will execute,
and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, will authenticate and deliver Physical Notes to each such beneficial owner of the related Notes (or a portion thereof)
in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note shall be cancelled. 

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) shall be registered in such names
and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. 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,
cancelled, repurchased or transferred, such Global Note shall be, upon receipt thereof, cancelled 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, cancelled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such
Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement
shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 

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

(d) [Reserved] 
 (e) Any Note that
is repurchased or owned by the Company or any Subsidiary thereof may not be resold by the Company or such Subsidiary 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 no longer being “restricted securities” (as defined under Rule 144 under the Securities Act). 

  
 19 








 Section 2.06 Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall
become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number
not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to
the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every
case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of
such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the Holder of a sum sufficient to cover
any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about
to be converted in accordance with Article 13 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the
conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating
agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory
to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

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

Section 2.07 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 

  
 20 








 
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 will execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each
office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such
exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as
Physical Notes authenticated and delivered hereunder. 
 Section 2.08 Cancellation of Notes Paid, Converted, Etc. The Company
shall cause all Notes surrendered for the purpose of payment, repurchase, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or controlled
Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be cancelled promptly by it, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of
this Indenture. The Trustee shall dispose of cancelled 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. If the Company or any of its Subsidiaries shall acquire any of the Notes, such acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to
the Trustee for cancellation. Any Notes surrendered for cancellation shall not be reissued or resold and shall be promptly cancelled. 

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 will 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 (except that the first Interest Payment Date and the date from which interest may accrue may be different) in
an unlimited aggregate principal amount; provided that such additional Notes must be part of the same issue as the Notes initially issued hereunder for U.S. federal income tax purposes if represented by the same CUSIP number (including, if relevant,
an unrestricted CUSIP number) as the Notes initially issued hereunder. 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 16.05, as the Trustee shall reasonably request. In addition, the 

  
 21 








 
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 private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. Any Notes repurchased by the Company may, at
the Company’s option, be surrendered to the Trustee for cancellation in accordance with Section 2.08, but shall not be reissued or resold by the Company. 

ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01 Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officers’
Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore authenticated and
delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust or segregated and
held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d)) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or
delivered to Holders, as applicable, after all outstanding Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or cash, shares of Common Stock or a combination
thereof, as applicable, solely to satisfy the Company’s Conversion Obligation, sufficient to pay all of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and (b) the Company has delivered to the
Trustee an 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 of,
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 Borough of Manhattan, The City of New York, an
office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices
and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or
agency of the Trustee in the Borough of Manhattan, The City of New York. 

  
 22 








 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 Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of
any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate
Trust Office and the office or agency of the Trustee in the Borough of Manhattan, The City of New York, each shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 

Section 4.03 Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy
in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder. 

Section 4.04 Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the
Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 

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

(ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal of, 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 of, the Fundamental Change Repurchase
Price, if applicable, of, or accrued and unpaid interest on, the Notes, deposit with the Trustee (or other Paying Agent) a sum sufficient to pay such principal, 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 10:00 a.m.,
New York City time, on such date. 

  
 23 








 (b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the
principal of, the Fundamental Change Repurchase Price, if applicable, of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal, 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 of, 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) 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 of, the Fundamental Change Repurchase Price, if applicable, of, and accrued and unpaid interest on, or consideration due upon the conversion of, any Note and remaining unclaimed for two years
after such principal, the Fundamental Change Repurchase Price, if applicable, or interest has become due and payable shall be paid to the Company on request of the Company contained in an Officers’ Certificate, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money
and 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
remains 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 will 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 Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issued 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 any Holder, beneficial owner or prospective purchaser of such Notes or any such shares, upon written request, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act (or any other provision of Rule 144A, as such rule may be amended from time to time), to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule
144A under the Securities Act, as such rule may be amended from time to time. 

  
 24 








 (b) The Company shall file with the Trustee within 15 days after the same are required to be
filed with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the
Exchange Act). Any such document or report that the Company files with the Commission via the Commission’s Electronic Data Gathering, Analysis, and Retrieval (“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 and documents
described in subsection (b) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officers’ Certificate). 

(d) If (i) 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, (x) 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 (y) the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates (as a result of restrictions pursuant to U.S. securities law or the
terms of this Indenture or the Notes), or (ii) as of the 365th day after the last date of original issuance of the Notes offered hereby, the restrictive legend on the Notes specified in Section 2.05(c) has not been removed, the Notes are
assigned a restricted CUSIP or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates (without restrictions pursuant to U.S. securities law or the terms of this Indenture or the Notes) (each such event
referred to in clause (i) or clause (ii) above, a “Restricted Transfer Default”), and, in either case, the Company has not cured any such Restricted Transfer Default by the date that is 14 calendar days following the
occurrence of such Restricted Transfer Default (the “Restricted Transfer Triggering Date”), then the Company shall pay Additional Interest in cash on the Notes. Additional Interest shall accrue on the Notes at the rate of
0.25% per annum of the principal amount of Notes outstanding for the first 90 days for which the Restricted Transfer Default has occurred and is continuing after the Restricted Transfer Triggering Date and thereafter will accrue at the rate of
0.50% per annum of the principal amount of Notes outstanding for which the Restricted Transfer Default has occurred and is continuing after the Restricted Transfer Triggering Date. 

Notwithstanding the foregoing, if, as of the 365th day after the last date of original issuance of the Notes offered hereby, the restrictive
legend on the Notes specified in Section 2.05(c) has not been removed or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates (without restrictions pursuant to U.S. securities law or the terms of this
Indenture or the Notes), the Company may elect to designate an effective shelf registration statement for the resale of the Notes or any Common Stock issuable upon conversion of the Notes. Additional Interest shall not accrue for each day on which
such registration statement remains effective and usable by Holders for the resale of the Notes or any Common Stock issuable upon conversion of the Notes. Any such registration shall be effected on terms customary for convertible notes generally
offered in reliance upon Rule 144A under the Securities Act. 

  
 25 








 Additional Interest will be payable in arrears on each Interest Payment Date following accrual in
the same manner as regular interest on the Notes. 
 (e) The Additional Interest that is payable in accordance with Section 4.06(d)
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. 

(f) If Additional Interest is payable by the Company pursuant to Section 4.06(d), the Company shall deliver to the Trustee an
Officers’ Certificate (upon which the Trustee may rely conclusively) 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 Investment Company Act. The Company covenants that for the period of time during which Notes are outstanding, the
Company shall not violate, whether or not the Company is subject to, Section 18(a)(1)(A) as modified by Section 61(a)(1) of the Investment Company Act or any successor provisions thereto of the Investment Company Act, as such obligation
may be amended or superseded but giving effect to any exemptive relief that may be granted to the Company by the Commission. 

Section 4.08 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at
any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or
interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly
waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted. 
 Section 4.09 Statement as to Compliance. The Company will deliver to the
Trustee, within 120 days after the end of each fiscal year ending after the date hereof so long as any Note is outstanding hereunder, an Officers’ Certificate stating to the knowledge of the signers thereof whether the Company is in default in
the performance of any of the terms, provisions or conditions of this Indenture. For purposes of this Section 4.09, such default shall be determined without regard to any period of grace or requirement of notice under this Indenture. 

Section 4.10 Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

the Trustee may request in writing, within 30 days after receipt by the Company of any such request (or such lesser time as the Trustee may reasonably request in order to enable it to timely provide any notice to be provided by it hereunder), a list

100% of the principal of, and accrued and unpaid interest, if any, on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically
be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 6.01(j) or Section 6.01(k) with respect to the Company, but not any of its
Significant Subsidiaries, occurs and is continuing, the principal of, and accrued and unpaid interest, if any, on, all Notes shall be automatically and immediately due and payable. 

This provision, however, is subject to the condition 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 moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or deliver, as the case may be, or shall deposit with the Trustee an amount of cash
and/or shares of Common Stock sufficient to pay all matured installments of interest upon all the Notes, all amounts of consideration due upon the conversion of any and all converted Notes, and the principal of any and all Notes which shall have
become due otherwise than by acceleration (with interest upon such principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest, at the rate or rates, if any, specified in the
Notes to the date of such payment or deposit) and such amounts due to the Trustee pursuant to Section 7.06, and if any and all Events of Default under this Indenture, other than the nonpayment of the principal of Notes which shall have become
due by acceleration, shall have been cured, waived, or otherwise remedied pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount
of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or
shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the
principal of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required, (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iv) a
breach of a covenant that cannot be modified or amended without the consent of each Holder pursuant to Section 10.02. 

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 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 (a) 0.25% per annum of the principal amount of the Notes outstanding for each day during the 90-day period beginning on, and including, the date on which such an Event of
Default first occurs and (b) 0.50% per annum of the principal amount of the Notes outstanding for each day during the 90-day period beginning on, and including, the 91st day following, and including, the occurrence of such an Event of
Default during which such Event of Default is continuing. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d). If the Company elects
to pay Additional Interest pursuant to this Section 6.03, 

  
 29 








 
such Additional Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. On the 181st 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 181st day), the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Additional Interest following an Event
of Default in accordance with this Section 6.03, the Notes shall be subject to acceleration as provided in Section 6.02. 
 In
order to elect to pay Additional Interest as the sole remedy during the first 180 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and
the Paying Agent of such election prior to the beginning of such 180-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 

Section 6.04 Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of
Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay or deliver, as the case may be, to it, for the benefit of the Holders of the Notes, the whole amount then due and payable or deliverable on the Notes (i.e.,
principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate or rates, if any, specified in 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 or deliver, as the case may be, 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 and amounts so due but unpaid or not delivered, 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 or amounts adjudged or decreed to be payable or deliverable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. In such event, the Trustee shall be entitled to be reimbursed
or indemnified for any and all amounts reasonably expended in connection therewith (including fees and expenses of counsel) in accordance with the terms of Section 7.06 hereof. 

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,


  
 30 








 
its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction
of any amounts due the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the
Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements,
including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and
disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the
Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition affecting the Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the
possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery
of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or
abandoned because of a waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the 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, subject to applicable law, 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: 

  
 31 








 First, to the payment of all amounts due the Trustee under Section 7.06; 

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any
cash due upon conversion of, the Notes in default in the order of the due date 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 or rates, if any, specified in 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 or, if applicable, the payment of the Fundamental Change
Repurchase Price or any cash due upon conversion shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount then owing and unpaid upon the Notes for principal, interest, the Fundamental Change Repurchase
Price or cash due upon conversion, 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 or rates, if any, specified in 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, interest, the Fundamental Change Repurchase Price or cash due upon conversion without
preference or priority of any such amount over each other (including 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, accrued and unpaid interest, the Fundamental Change Repurchase Price or cash due upon conversion; 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, the Fundamental Change Repurchase
Price, if applicable, or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute
any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless: 

(a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein
provided; 
 (b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the
Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 
 (c) such Holders shall have offered to the
Trustee such security or indemnity reasonably satisfactory to it against any costs, loss, liability or expense (including fees and expenses of its counsel) to be incurred therein or thereby; 

(d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any
such action, suit or proceeding; and 

  
 32 








 (e) no direction that, in the opinion of the Trustee, is inconsistent with such written request
shall have been given to the Trustee by the Holders of a majority in principal amount of the Notes outstanding within such 60-day period pursuant to Section 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, the right of any Holder to receive payment or delivery,
as the case may be, of (w) the principal of, (x) the Fundamental Change Repurchase Price, if applicable, of, (y) accrued and unpaid interest 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 deliver, as the case may be, on or after such respective dates against the Company shall not be
impaired or affected without the consent of such Holder. 
 Section 6.07 Proceedings by Trustee. In case of an Event of Default
the Trustee may in its discretion (and subject to the provisions of Section 7.01 and Section 7.06) proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to
protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

Section 6.08 Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.06, all powers and
remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes,
by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power
accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every
power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 

Section 6.09 Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority in 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 

  
 33 








 
place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such
direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction and (c) the Trustee may demand security or
indemnity reasonably satisfactory to it in accordance with Section 7.01. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal
liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default
hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal of, the Notes when due that has not been cured pursuant to the provisions of Section 6.02, (ii) a failure
by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes, (iii) a default in the payment of the Fundamental Change Repurchase Price or (iv) a default in respect of a covenant or provision
hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions
and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this
Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default
or impair any right consequent thereon. 
 Section 6.10 Notice of Defaults. The Trustee shall, within 90 days after the
occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, mail to all Holders as the names and addresses of such Holders appear upon the Note Register, notice of all Defaults known to a Responsible Officer, unless
such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of, or accrued and unpaid interest on, any of the Notes or a Default in the payment of the
Fundamental Change Repurchase Price, if applicable, 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 determine that the withholding of such notice is in the interests of the Holders. 
 Section 6.11
Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right
or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its
discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that
the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee 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 Fundamental Change Repurchase Price with respect to the Notes being repurchased as provided in this Indenture) on or after the due date expressed or provided for in such Note or to
any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 13.

 ARTICLE 7 

CONCERNING THE TRUSTEE 

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

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

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

  
 35 








 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it
in good faith in accordance with the direction of the Holders of not less than a majority in 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 or refraining from taking any action believed in good faith to be beyond the scope of its powers, under this Indenture; 

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

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

(g) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest bearing
trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or the
failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any
amounts held hereunder in the absence of such written investment direction from the Company; and 
 (h) in the event that the Trustee is also
acting as Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note
Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or transfer agent. 
 None of the provisions contained in this Indenture
shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 

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

(a) the Trustee may conclusively rely and 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; 

  
 36 








 (b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently
evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary
of the Company; 
 (c) the Trustee may consult with counsel 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) 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 
 (f) the permissive rights of the Trustee enumerated herein shall not be construed as duties. 

In no event shall the Trustee be liable for any consequential loss or damage of any kind whatsoever (including but not limited to lost
profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than any such loss or damage caused by the Trustee’s willful misconduct or gross negligence. The Trustee shall
not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or
Event of Default shall have been given to the Trustee by the Company or by any Holder of the Notes. 
 Section 7.03 No
Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any
Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 
 Section 7.04 Trustee,
Paying Agents, Conversion Agents, Bid Solicitation Agent or Note Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent, Bid Solicitation Agent 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. 

  
 37 








 Section 7.05 Monies and Shares of Common Stock to Be Held in Trust. All monies and
shares of Common Stock received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money and shares of Common Stock held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money or shares of Common Stock received by it hereunder except as may be agreed 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, reasonable compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as
mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance
with any of the provisions of this Indenture in any capacity thereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense,
disbursement or advance as shall have been caused by its gross negligence, willful misconduct or bad faith. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into
in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee,
its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs
and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements
and advances shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the
benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The obligation of the Company
under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be
unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee. 

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating
agent incur expenses or render services after an Event of Default specified in Section 6.01(j) or Section 6.01(k) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any
bankruptcy, insolvency or similar laws. 

  
 38 








 Section 7.07 Officers’ Certificate as Evidence. Except as otherwise provided in
Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an
Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall be full warrant to the Trustee for any
action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 
 Section 7.08 Eligibility of
Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act 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 mailing notice thereof to the Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee
shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition any
court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11, on behalf of himself and all
others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

(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, 

  
 39 








 then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.11, any
Holder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with
Section 8.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within 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) The Trustee may be removed at any time with respect to the Notes by the Company, by an Officers’ Certificate delivered to the Trustee,
provided that contemporaneously therewith (x) the Company immediately appoints a successor Trustee with respect to the Notes meeting the requirements of Section 7.08 hereof and (y) the terms of Section 7.10 hereof are complied
with in respect of such appointment (the Trustee being removed hereby agreeing to execute the instrument contemplated by Section 7.10 hereof, if applicable, under such circumstances) and provided further that no Default or Event of Default with
respect to the Notes shall have occurred and then be continuing at such time. 
 (e) Any resignation or removal of the Trustee and
appointment of a successor trustee pursuant to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 

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

  
 40 








 No successor trustee shall accept appointment as provided in this Section 7.10 unless at the
time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08. 
 Upon acceptance of
appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such
trustee hereunder to the Holders at their addresses as they shall appear on the Note Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company. 
 Section 7.11 Succession by Merger, Etc. Any corporation or other entity
into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other
entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any
further act on the part of any of the parties hereto; provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be
eligible under the provisions of Section 7.08. 
 In case at the time such successor to the Trustee shall succeed to the trusts created
by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor
trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes
either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate
of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by
merger, conversion or consolidation. 
 Section 7.12 Trustee’s Application for Instructions from the Company. Any
application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at
the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not
be liable 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 in aggregate
principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of
such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of the Holders
voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders. Whenever the
Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining Holders entitled to
take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 

Section 8.02 Proof of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and
Section 9.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06. 

Section 8.03 Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion
Agent and any Note Registrar shall deem the Person in whose name a Note shall be registered upon the Note Register to be, and shall treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any
notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03) accrued and unpaid interest
on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so
made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note. Notwithstanding anything to the contrary
in this Indenture or the Notes following an Event of Default, any Holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the
Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture. 

  
 42 








 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 or by any Affiliate of the Company shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer knows
are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s
right to so act with respect to such Notes and that the pledgee is not the Company or an Affiliate of the Company. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to
the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an 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 in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any
Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 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.

Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Company shall not consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to, another Person (provided that a pledge of its assets pursuant to any Credit Facility shall
be deemed not to be a sale, conveyance, transfer or lease), 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.

the Company, such Successor Company shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part, except in the case of a lease of all or substantially all of the
Company’s properties and assets. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all of the Notes issuable hereunder which theretofore shall not have been
signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall

 48 








 
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. 

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance)
may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 11.03 Opinion of Counsel to Be Given to
Trustee. No consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive as conclusive evidence an Officers’ Certificate and an Opinion of Counsel that any such consolidation, merger, sale,

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

described in Section 13.01(b), at any time prior to the close of business on the Business Day immediately preceding August 1, 2021 under the circumstances and during the periods set forth in Section 13.01(b), and
(ii) irrespective of the conditions described in Section 13.01(b), on or after August 1, 2021 and prior to the close of business on the Scheduled Trading Day immediately preceding 

  
 49 








 
the Maturity Date, in each case, at an initial conversion rate of 60.9366 shares of Common Stock (subject to adjustment as provided in Section 13.04, the “Conversion Rate”)
per $1,000 principal amount of Notes (subject to the settlement provisions of Section 13.02, the “Conversion Obligation”). 

(b) (i) Prior to the close of business on the Business Day immediately preceding August 1, 2021, the Notes may be surrendered for
conversion during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request
by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading Day. The
Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent of the three
independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent shall have no obligation to determine the
Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination and provided it with the names and contact information for such three independent nationally recognized securities dealers; and the Company shall
have no obligation to make such request unless Holders of at least $2,000,000 aggregate principal amount of Notes provide the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the
product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent to 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 the Company
does not instruct the Bid Solicitation Agent to determine in the manner provided herein, the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation
Agent to obtain bids and the Bid Solicitation Agent fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of
the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If,
at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable
Conversion Rate, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee). 

  
 50 








 (ii) If, prior to the close of business on the Business Day immediately preceding
August 1, 2021, the Company elects to: 
 (A) issue to all or substantially all holders of its Common Stock any rights,
options or warrants 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 its 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 its Common Stock the Company’s assets, debt securities or rights to
purchase securities of the Company, which distribution has a per share value, as 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 all Holders of the Notes, the Trustee and the Conversion Agent (if other than the
Trustee) at least 25 Scheduled Trading Days prior to the Ex- Dividend Date for such issuance or distribution. Once the Company has given such notice, the Notes may be surrendered for conversion at any time until the earlier of (1) the close of
business on the Business Day immediately 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, even if the Notes are not otherwise
convertible at such time. Notwithstanding the foregoing, no Notes may be surrendered for conversion if Holders participate, 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 clauses (A) or (B) of this subsection (ii) 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. For purposes of Section 13.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such
average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate
offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such
consideration, if other than cash, to be determined by the Board of Directors. 
 (iii) If a transaction or event that
constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding August 1, 2021, regardless of whether a Holder has the right to require the Company to
repurchase the Notes pursuant to Section 14.01, 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, pursuant to which the Common Stock would be
converted into cash, securities or other assets, the Notes may be surrendered for conversion at any time from or after the date that is 25 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business
Day after the Company gives notice of such transaction) until 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date.
The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly 

  
 51 








 
as practicable following the date the Company publicly announces such transaction but in no event less than 25 Scheduled Trading Days prior to the anticipated effective date of such transaction
or (ii) if the Company does not have knowledge of such transaction at least 25 Scheduled Trading Days prior to the anticipated effective date of such transaction, within two Business Days of the date upon which the Company receives notice, or
otherwise becomes aware, of such transaction but in no event later than the actual effective date of such transaction. 

(iv) Prior to the close of business on the Business Day immediately preceding August 1, 2021, the Notes may be surrendered
for conversion during any calendar quarter commencing after the calendar quarter ending on March 31, 2017 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not
consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter as reported to the Conversion Agent by the Company is greater than or equal to 130% of the Conversion Price on
each applicable Trading Day. Upon receipt of and on the basis of such report from the Company, the Conversion Agent, on behalf of the Company, shall determine at the beginning of each calendar quarter commencing after March 31, 2017 whether the
Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Company and the Trustee if the Notes become convertible in accordance with this clause (iv), and after receipt of such notice the Company shall so
notify the Holders. 
 Section 13.02 Conversion Procedure; Settlement Upon Conversion. 

(a) Subject to this Section 13.02, Section 13.03(b) and Section 13.07(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 any
fractional share of Common Stock in accordance with subsection (j) of this Section 13.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of any
fractional share of Common Stock in accordance with subsection (j) of this Section 13.02 (“Combination Settlement”), at its election, as set forth in this Section 13.02. 

(i) All conversions occurring on or after August 1, 2021shall be settled using the same Settlement Method. 

(ii) Prior to August 1, 2021, the Company shall use the same Settlement Method for all conversions occurring on the same
Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates. 

(iii) If, in respect of any Conversion Date (or any conversions of Notes occurring during the period beginning on, but
excluding, August 1, 2021 and ending on, and including, the Business Day immediately preceding the Maturity Date, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant


  
 52 








 
Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to converting Holders no later
than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions occurring on or after August 1, 2021, no later than August 1, 2021). If the Company does not elect a
Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination
Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of
Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified
Dollar Amount in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. 

(iv) The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes
(the “Settlement Amount”) shall be computed by the Company 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 an amount in cash equal to the sum of the Daily Conversion Values for each of the 15
consecutive Trading Days during the related Observation Period; and 
 (C) if the Company elects (or is deemed to have
elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount
equal to the sum of the Daily Settlement Amounts for each of the 15 consecutive Trading Days during the related Observation Period. 

(v) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the
Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of any fractional share,
the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of fractional shares of Common
Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 

  
 53 








 (b) Subject to Section 13.02(e), before any Holder of a Note shall be entitled to convert a
Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which
such Holder is not entitled as set forth in Section 13.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of
Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such
Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by
appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest
Payment Date to which such Holder is not entitled as set forth in Section 13.02(h). The Trustee (and, if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 13 on the Conversion Date for such
conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company (or Paying Agent) in respect of such Notes and not validly
withdrawn such Fundamental Change Repurchase Notice in accordance with Section 14.02. 
 If more than one Note shall be surrendered for
conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so
surrendered. 
 (c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the
“Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as provided in Section 13.03(b) and in Section 13.07, the Company shall pay or deliver, as the case may
be, the consideration due in respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following the last
Trading Day of the Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to such Holder, or such Holder’s nominee
or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the portion of the Company’s Conversion Obligation that consists
of shares of Common Stock, and, on or prior to such issuance, the Company shall give the Conversion Agent notice of the number of shares of Common Stock being so issued and the method by which the issuance shall take place. Any required funds due to
a converting Holder in connection with a Cash Settlement or Combination Settlement shall be delivered to the Paying Agent and such Holder, or such Holder’s nominee or nominees, in accordance with the same procedures that apply in connection
with the payment of the Fundamental Change Repurchase Price as set forth in Section 14.03. 

  
 54 








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

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue
of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to
deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately
preceding sentence. 
 (f) Except as provided in Section 13.04, no adjustment shall be made for dividends on any shares issued upon the
conversion of any Note as provided in this Article 14. 
 (g) Upon the conversion of an interest in a Global Note, the Trustee, or the
Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any
Conversion Agent other than the Trustee. 
 (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid
interest, if any, except as set forth below. The Company’s settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not
including, the Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a
combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular
Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered
for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so
converted; provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a 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 (3) to the extent of any Defaulted Amounts, if any Defaulted Amounts exist at the time of conversion with respect to such
Note. 

  
 55 








 (i) The Person in whose name the certificate for any shares of Common Stock delivered upon
conversion is registered shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of
the relevant Observation Period (if the Company elects (or is deemed to have elected) to satisfy the related Conversion Obligation by Combination Settlement), as the case may be, in each case solely for the purpose of receiving or participating in
any dividend, distribution, issuance, share split or combination, tender or exchange offer or any other event that would lead to a Conversion Rate adjustment as described in Section 13.04. 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 any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last
Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected (or is deemed to have elected) Combination Settlement, the full number of shares that shall
be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Observation Period and any fractional shares remaining after such computation shall be paid in cash. 

(k) Notwithstanding anything to the contrary herein, no Holder shall be entitled to receive shares of Common Stock upon conversion to the
extent (but only to the extent) that such receipt would cause such converting Holder to become, directly or indirectly, a “beneficial owner” (within the meaning of Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder) of more than 5.0% of the shares of Common Stock outstanding at such time (the “Limitation”). Any purported delivery of shares of Common Stock upon conversion of Notes shall be void and have no effect to the
extent (but only to the extent) that such delivery would result in the converting Holder becoming the beneficial owner of more than the Limitation. If any delivery of shares of Common Stock owed to a Holder upon conversion of Notes is not made, in
whole or in part, as a result of the Limitation, the Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such shares as promptly as practicable after any such converting Holder gives notice to the
Company that such delivery would not result in it being the beneficial owner of more than 5.0% of the shares of Common Stock outstanding at such time. The Limitation shall no longer apply following the effective date of any Fundamental Change. 

Section 13.03 Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.
(a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes
so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be 

  
 56 








 
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, the 35th calendar day immediately following the Effective Date of such Make-Whole Fundamental Change). 

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to Section 13.01(b)(iii), the
Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 13.02; provided, however, that if, at the effective time of a
Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change,
the Conversion Obligation per $1,000 principal amount of converted Notes shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the
Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall
notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table
below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share of the Common Stock in
the Make-Whole Fundamental Change. If the holders of the Common Stock receive 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. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the
Conversion Rate where the Ex-Dividend Date of the event occurs, during such five consecutive Trading Day period. 
 (d) The Stock Prices set
forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment,
multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of
Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 13.04. 

  
 57 








 (e) The following table sets forth the number of Additional Shares to be received per $1,000
principal amount of Notes pursuant to this Section 13.03 for each Stock Price and Effective Date set forth below.

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

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in
the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based
on a 365-day year; 
 (ii) if the Stock Price is greater than $24.00 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 $14.27 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 total number of shares of Common Stock issuable upon conversion exceed 70.0770 per
$1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 13.04. 
 (f)
Nothing in this Section 13.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 13.04 in respect of a Make-Whole Fundamental Change. 

Section 13.04 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 a share split or share combination), at the same time and upon the same terms as
holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 13.04, 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. 

  
 58 








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

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

 Any adjustment made under this Section 13.04(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 13.04(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
its Common Stock any rights, options or warrants 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
adjusted based on the following formula: 
  

							
		 	CR1    =    CR0    × 
   	 	OS0 + X	  	
		 	 	OS0 + Y	  	

 where, 
  

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


  
 59 








 Any increase made under this Section 13.04(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 such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred. 

For purposes of this Section 13.04(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or
purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of
such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or
conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
 (c) If the Company
distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property 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 was effected pursuant to Section 13.04(a) or Section 13.04(b), (ii) dividends or distributions paid exclusively in cash and (iii) Spin-Offs as to
which the provisions set forth below in this Section 13.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of
the Company, the “Distributed Property”), then the Conversion Rate shall be adjusted based on the following formula: 
  

							
		 	CR1    =    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;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.


  
 60 








 Any increase made under the portion of this Section 13.04(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 dividend or 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 of Distributed Property such Holder would have received if
such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of
this Section 13.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock
over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution. 

With respect to an adjustment pursuant to this Section 13.04(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 adjusted based on the following formula: 
  

							
		 	CR1    =    CR0    × 
   	 	FMV0 + MP0	  	
		 	 	MP0	  	

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the last Trading Day of the Valuation Period;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on the last Trading Day 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.


  
 61 








 The adjustment to the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the
Valuation Period; provided that in respect of any conversion during the Valuation Period, references in the portion of this Section 13.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced with such lesser number
of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the Conversion Date in determining the Conversion Rate. 

For purposes of this Section 13.04(c) (and subject in all respect to Section 13.11), rights, options or warrants distributed by the
Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the
occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of
the Common Stock, shall be deemed not to have been distributed for purposes of this Section 13.04(c) (and no adjustment to the Conversion Rate under this Section 13.04(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 13.04(c). If any such right, option or
warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different
securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights
(in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options
or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate
under this Section 13.04(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,


  
 62 








 
options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or
been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 

For purposes of Section 13.04(a), Section 13.04(b) and this Section 13.04(c), any dividend or distribution to which this
Section 13.04(c) is applicable that also includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which
Section 13.04(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options
or warrants to which Section 13.04(b) is applicable (the “Clause B Distribution”), 
 then (1) such dividend or distribution,
other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 13.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment
required by this Section 13.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion
Rate adjustment required by Section 13.04(a) and Section 13.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B
Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to
the open of business on such Ex-Dividend Date or effective date” within the meaning of Section 13.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 13.04(b).

 (d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, other than a regular, quarterly
cash dividend that does not exceed the applicable Dividend Threshold for the calendar year during which the Ex-Dividend Date falls and which is subject to adjustment as described below, the conversion rate will be adjusted based on the following
formula: 
  

							
		 	CR1    =    CR0    × 
   	 	SP0 – T	  	
		 	 	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;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
			
	T	  	=	  	the applicable Dividend Threshold; provided that if the dividend or distribution is not a regular quarterly cash dividend, the applicable Dividend Threshold will be deemed to be zero; and
			
	C	  	=	  	the amount in cash per share the Company distributes to holders of its Common Stock.


  
 63 








 The applicable Dividend Threshold shall be subject to adjustment in a manner inversely proportional to
adjustments to the Conversion Rate; provided that no adjustment shall be made to the applicable Dividend Threshold for any adjustment to the Conversion Rate pursuant to this Section 13.04(d). 

Any increase pursuant to this Section 13.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for
such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms
as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution.

 (e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock, to the extent
that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock on 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 adjusted based on the following formula: 
  

							
		 	CR1    =    CR0    × 
   	 	AC + (SP1 × OS1)	  	
		 	 	OS0 × SP1	  	

 where, 
  

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

 The adjustment to the Conversion Rate under this Section 13.04(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 in respect of any conversion within the 10 Trading Days immediately following, and including, the
expiration date of any tender or exchange offer, references in this Section 13.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange
offer expires and the Conversion Date in determining the Conversion Rate. 

  
 64 








 (f) Notwithstanding this Section 13.04 or any other provision of this Indenture or the
Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the
shares of Common Stock as of the related Conversion Date as described under Section 13.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this
Section 13.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an
unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 
 (g) Except as stated
herein, the Company shall not adjust the Conversion Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or such
convertible or exchangeable securities. 
 (h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of
this Section 13.04, and to the extent permitted by applicable law and subject to the applicable rules of The New York Stock Exchange, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20
Business Days if the Board of Directors 

  
 65 








 
determines that such increase would be in the Company’s best interest. In addition, but subject to the same limitations set forth in the immediately preceding sentence, 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 (or rights to acquire shares) or similar
event. Whenever the Conversion Rate is adjusted pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior
to the date the adjusted Conversion Rate takes effect, and such notice shall state the adjusted Conversion Rate and the period during which it will be in effect. 

(i) Notwithstanding anything to the contrary in this Article 13, the Conversion Rate shall not be adjusted: 

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

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or
future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries; 

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

(iv) solely for a change in the par value of the Common Stock or a change in the Company’s jurisdiction of incorporation;
or 
 (v) for accrued and unpaid interest, if any. 

(j) All calculations and other determinations under this Article 13 shall be made by the Company and shall be made to the nearest one-ten
thousandth (1/10,000) of a share. The Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate. However, the Company shall carry forward any
adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustment, regardless of whether the aggregate adjustment is less than 1%, on the Conversion Date for any Notes and on each Trading Day of any Observation Period
for any converted Notes. 
 (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee
(and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of
the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is
still in effect. Promptly after delivery of such 

  
 66 








 
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
the Trustee, on the Company’s behalf, shall mail such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of this Indenture. Failure to deliver such notice shall not affect the
legality or validity of any such adjustment. 
 Section 13.05 Adjustments of Prices. Whenever any provision of this Indenture
requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock
Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the
Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 

Section 13.06 Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued
shares, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming that at the time of computation of such number of shares, all such Notes would be converted by a
single Holder and that Physical Settlement is applicable). 
 Section 13.07 Effect of Recapitalizations, Reclassifications and
Changes of the Common Stock. 
 (a) In the case of: 

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or
combination or a change solely in par value), 
 (ii) any consolidation, merger or combination involving the Company, 

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

in each case, as a result of which the Common Stock then outstanding 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


  
 67 








 
Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or
purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01(f) providing for such change in the right to convert each $1,000 principal amount of 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 13.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 13.02 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 13.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such
Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 
 If the Merger Event causes
the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will
be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (ii) the unit of Reference Property for purposes of the
immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders receive only cash in such Merger Event, then for all conversions that occur after the effective
date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional
Shares pursuant to Section 13.03), multiplied by the price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day
immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments that shall be as nearly
equivalent as is possible to the adjustments provided for in this Article 13. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of
a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests
of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the purchase rights set
forth in Article 14. 
 (b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this
Section 13.07, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise the Reference Property after any
such Merger Event, any 

  
 68 








 
adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the
execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality
or validity of such supplemental indenture. 
 (c) The Company shall not become a party to any Merger Event unless its terms are consistent
with this Section 13.07 in all material respects. None of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as
applicable, as set forth in Section 13.01 and Section 13.02 prior to the effective date of such Merger Event. 
 (d) The above
provisions of this Section shall similarly apply to successive Merger Events. 
 (e) In connection with any Merger Event, the applicable
Dividend Threshold shall be subject to adjustment as described in clause (i), clause (ii) or clause (iii) below, as the case may be. 

(i) In the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to subsection
(a) above and excluding any dissenters’ appraisal rights) is composed entirely of shares of common stock (the “Merger Common Stock”), the applicable Dividend Threshold at and after the effective time of such Merger Event
will be equal to (x) the applicable Dividend Threshold immediately prior to the effective time of such Merger Event, divided by (y) the number of shares of Merger Common Stock that a holder of one share of Common Stock would receive
in such Merger Event (such quotient rounded down to nearest cent). 
 (ii) In the case of a Merger Event in which the
Reference Property (determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed in part of shares of Merger Common Stock, the applicable Dividend Threshold at and after the
effective time of such Merger Event will be equal to (x) the applicable Dividend Threshold immediately prior to the effective time of such Merger Event, multiplied by (y) the Merger Valuation Percentage for such Merger Event (such
product rounded down to nearest cent). 
 (iii) For the avoidance of doubt, in the case of a Merger Event in which the
Reference Property (determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed entirely of consideration other than shares of common stock, the applicable Dividend Threshold at
and after the effective time of such Merger Event will be equal to zero. 
 Section 13.08 Certain Covenants. (a) The
Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges (other than those created by the Holder) with respect to the issue
thereof. 

  
 69 








 (b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of
conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules
and interpretations of the Commission, secure such registration or approval, as the case may be. 
 (c) The Company further covenants that if
at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any
Common Stock issuable upon conversion of the Notes. 
 Section 13.09 Responsibility of Trustee. The Trustee (including in its
capacity as Conversion Agent) 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 (including in its capacity as Conversion Agent) 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 13.07 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 13.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, the 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 13.01(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 13.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may
conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 13.01(b). 

  
 70 








 Section 13.10 Notice to Holders Prior to Certain Actions. In case of any: 

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 13.04 or
Section 13.11; 
 (b) Merger Event; or 

(c) Voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries; 

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

Section 13.11 Stockholder Rights Plans. To the extent that the Company has a rights plan in effect upon conversion of the Notes,
each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in
each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. If at the time of conversion, however, the rights have separated from the shares of Common Stock in accordance with the
provisions of the applicable stockholder rights plan so that the Holders would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon conversion of the Notes, the Conversion Rate shall be adjusted at the time of
separation as if the Company distributed to all or substantially all holders of Common Stock Distributed Property as provided in Section 13.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

 Section 13.12 Limit on Issuance of Shares of Common Stock Upon Conversion. Notwithstanding anything to the contrary in this
Indenture, if an event occurs (including pursuant to Section 13.03 and subsections Section 13.04(b), Section 13.04(c), Section 13.04(d), Section 13.04(e) and Section 13.04(h) of Section 13.04) that would result in
an increase in the Conversion Rate by an amount in excess of limitations imposed by any shareholder approval rules or listing standards of any national or regional securities exchange (including the NASDAQ Global Select Market) that are applicable
to the Company, the Company will, at its option, either obtain stockholder approval of any issuance of Common Stock upon conversion of the Notes in excess such limitations or deliver cash in lieu of any shares of Common Stock otherwise 

  
 71 








 
deliverable upon conversions in excess of such limitations based on the Daily VWAP on each Trading Day of the relevant Observation Period in respect of which, in lieu of delivering shares of
Common Stock, the Company delivers cash pursuant to this Section 13.12. 
 ARTICLE 14 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 14.01 Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental
Change occurs at any time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of
$1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice (with such
Fundamental Change Repurchase Date being subject to postponement by a number of days by which the Company’s Fundamental Change Repurchase Notice is delivered to Holders beyond the deadline set forth in Section 14.01(c)), 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 14. 

(b) Repurchases of Notes under this Section 14.01 shall be made, at the option of the Holder thereof, upon: 

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

(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; 

  
 72 








 (ii) the portion of the principal amount of Notes to be repurchased, which must
be $1,000 or an integral multiple thereof; and 
 (iii) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase
Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the
Paying Agent a Fundamental Change Repurchase Notice contemplated by this Section 14.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business
Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 14.02. 

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 (i) the date that the Company knew or reasonably should have known
that the Fundamental Change occurred, in the case of a Fundamental Change described under clause (a) of the definition thereof, or (ii) the date the Fundamental Change occurred, in the case of any other Fundamental Change, the Company
shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the
Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. Such notice shall be by first class mail or, in the case of Global Notes, in accordance with the applicable procedures of the Depositary.
Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on
the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 

(i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 14; 

(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; 

  
 73 








 (vii) if applicable, the Conversion Rate and any adjustments to the Conversion
Rate; 
 (viii) if applicable, 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; 

(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 14.01. 
 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 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 the acceleration of the Notes (except in the case of an acceleration resulting from a
Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been
cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 14.02 Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn
(in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 14.02 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, 
 (ii) if Physical Notes have been issued, the certificate number of the Note
in respect of which such notice of withdrawal is being submitted, and 
 (iii) the principal amount, if any, of such Note
that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 

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

  
 74 








 Section 14.03 Deposit of Fundamental Change Repurchase Price. (a) The Company,
or its designee, 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 10:00 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. If any such designee does not deposit an amount of
money sufficient to repurchase all of such Notes by the deadline set forth in the immediately preceding sentence and the Company does not otherwise deposit such an amount by such deadline, such failure by the designee shall be treated for all
purposes of this Indenture as failure by the Company to make such deposit. In addition, failure by the Company to designate a designee to make the deposit required by the second immediately preceding sentence shall not relieve the Company of its
obligation to so deposit such an amount of money. Subject to extension if necessary to comply with the provisions of the Investment Company Act, 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 with respect to such Note (provided the Holder has satisfied the conditions in
Section 14.01) 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 14.01 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 a Fundamental Change Repurchase Date, return to the Company any funds in excess of the Fundamental Change Repurchase Price of the Notes, or portions thereof, that the Company is obligated
to purchase on the applicable Fundamental Change Repurchase Date. 
 (b) If by 10:00 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 pay the Fundamental Change Repurchase Price of all the Notes or portions thereof for which Holders have surrendered and not withdrawn Fundamental
Change Repurchase Notices on such Fundamental Change Repurchase Date, then (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the
Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price upon delivery or transfer of the Notes).

 (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 14.01, 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. 

  
 75 








 Section 14.04 Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In
connection with any repurchase offer pursuant to a Fundamental Change Repurchase Notice, the Company will, if required: 
 (a) comply with
the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable; 
 (b) file a
Schedule TO or any successor or similar schedule; 
 (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 14 to be exercised in the time
and in the manner specified in this Article 14.

sufficiency with respect to other Holders. If a notice or communication is mailed in the manner provided above, it is duly given, whether or not the addressee receives it. 

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to
Holders by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 

Section 16.04 Governing Law. THIS INDENTURE AND EACH NOTE, AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS
INDENTURE AND EACH NOTE, SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO THE CONFLICTS OF LAWS PROVISIONS THEREOF THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION).

 Section 16.05 Evidence of Compliance with Conditions Precedent; Certificates and Opinions of Counsel to Trustee. Upon any
application or demand by the Company to the Trustee to take any action under any of the provisions of this Indenture, the Company shall, if requested by the Trustee, furnish to the Trustee an Officers’ Certificate stating that such action is

 Each Officers’ Certificate provided for, by or on behalf of the Company in this Indenture

 77 








 Section 16.08 Benefits of Indenture. Nothing in this Indenture or in the Notes,
expressed or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Conversion Agent, any authenticating agent, any Note Registrar and their successors hereunder or the Holders, any benefit or any legal or equitable
right, remedy or claim under this Indenture. 
 Section 16.09 Table of Contents, Headings, Etc. The table of contents and the
titles and headings of the articles and sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof.

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

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

  
 78 








 The provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and
this Section 16.10 shall be applicable to any authenticating agent. 
 If an authenticating agent is appointed pursuant to this
Section, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

Section 16.11 Execution in Counterparts. This Indenture may be executed in any number of counterparts, each of which shall be an
original, but such counterparts shall together constitute but one and the same instrument. 
 Section 16.12 Severability. In the
event any provision of this Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or
impaired. 
 Section 16.13 Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 

Section 16.14 Force Majeure. In no event shall the Trustee, in each of its capacities, be responsible or liable for any failure or
delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military
disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that
are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

Section 16.15 Calculations. Except as otherwise provided in Section 13.01(b)(i), the Company shall be responsible for making
all calculations called for under the Notes. These calculations include, but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock, accrued interest payable on the Notes and the Conversion Rate of the Notes. The
Company shall make all these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders of Notes. The Company shall provide a schedule of its calculations to each of the Trustee and
the Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will forward the Company’s calculations to
any Holder of Notes upon the request of that Holder at the sole cost and expense of the Company.

 [FORM OF REVERSE OF NOTE] 

HERCULES CAPITAL, INC. 

4.375% Convertible Senior Note due 2022 

This Note is one of a duly authorized issue of Notes of the Company, designated as its 4.375% Convertible Senior Notes due 2022 (the
“Notes”), limited to the aggregate principal amount of $200,000,000 (or up to $230,000,000 if the Initial Purchaser exercises 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 January 25, 2017 (the “Indenture”), between the Company and U.S. Bank National Association (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is
hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount,
subject to certain conditions specified in the Indenture. 
 In case an Event of Default, as defined in the Indenture, shall have occurred
and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in
the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. 
 Subject to the terms and
conditions of the Indenture, the Company will make all payments in respect of the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect
such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
 No
reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal of, the Fundamental
Change Repurchase Price, if applicable, of, accrued and unpaid interest on and amounts due upon conversion of this Note at the place, at the respective times, at the rate and in the lawful money or other consideration herein prescribed. 

  
 A-6 








 The Notes are issuable in registered form without coupons in denominations of $1,000 principal
amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of
Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result
of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

The Notes are not subject to redemption through the operation of any sinking fund or otherwise. 

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase for
cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change 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 Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash,
shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 

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