 Exhibit 10.1 

TIMKENSTEEL CORPORATION 

CONVERTIBLE NOTES EXCHANGE AGREEMENT 

December 7, 2020 

[___________________] (the “Undersigned”), for itself and on behalf of the beneficial owners listed on Exhibit A
hereto (the “Accounts”) for whom the Undersigned holds contractual and investment authority (each Account, as well as the Undersigned if it is exchanging Old Notes (as defined below) hereunder, a “Holder”), enters
into this Exchange Agreement (this “Agreement”) with TimkenSteel Corporation, an Ohio corporation (the “Company”), as of the date first written above, whereby the Holders will exchange for each $1,000 principal
amount of the Company’s 6.00% Convertible Senior Notes due 2021 (the “Old Notes”), $1,000 principal amount of the Company’s new 6.00% Convertible Senior Notes due 2025 (the “New Notes”) that will be issued
pursuant to the provisions of a base indenture, dated as of May 31, 2016, which is attached hereto as part of Exhibit B (the “Base Indenture”), as supplemented by a supplemental indenture to be dated as of the Closing
Date (as defined below), the form of which is attached hereto as part of Exhibit B (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and U.S. Bank
National Association, as trustee (the “Trustee”). 
 On and subject to the terms hereof, the parties hereto agree as
follows: 
 Article I 

Exchange of Notes 

Section 1.1 Exchange. Subject to the terms and conditions set forth in this Agreement, at the Closing
(as defined below), the Undersigned hereby agrees to deliver to the Company, and to cause each Holder to deliver to the Company, the aggregate principal amount of the Company’s Old Notes specified on Exhibit A under the heading
“Exchanged Notes” in exchange for, and the Company hereby agrees to issue to each Holder, the principal amount of New Notes specified on Exhibit A under the heading “Holder New Notes.” The terms “Exchanged
Notes” and “Holder New Notes” as used herein with respect to each Holder mean the amounts specified on Exhibit A under the corresponding headings for such Holder. The transactions contemplated by this Agreement,
including the issuance, delivery and acceptance of the Holder New Notes and the exchange and sale of the Exchanged Notes, are collectively referred to herein as the “Transactions.”
 
 Section 1.2 Closing. Subject to the satisfaction (or waiver by the applicable parties) of
the conditions set forth in Section 4.1, the closing of the Transactions (the “Closing”) shall occur on December 15, 2020 or such other date as the parties may agree (the “Closing
Date”). At the Closing, (a) each Holder shall deliver or cause to be delivered to the Company all right, title and interest in and to its Exchanged Notes as specified on Exhibit A hereto, free and clear of any mortgage, lien,
pledge, charge, security interest, encumbrance, title retention agreement, option, equity or other adverse claim thereto (collectively, “Liens”), together with any documents of conveyance or transfer that the Company may deem
necessary or desirable to transfer to and confirm in the Company all right, title and interest in and to such Exchanged Notes, free and clear of any Liens and (b) the Company shall deliver to each Holder (i) the principal amount of the
Holder New Notes, as specified on Exhibit A hereto (or, if there are no Accounts, the Company shall deliver to the Undersigned, as the sole Holder, the Holder New Notes specified above) and (ii) a cash payment equal to the accrued and
unpaid interest payment on its Exchanged Notes as specified on Exhibit A from December 1, 2020 through, but not including, the Closing Date; provided, that the parties 












 
acknowledge that the delivery of the Holder New Notes may be delayed due to procedures and mechanics within the system of The Depository Trust Company (“DTC”) or the New York
Stock Exchange (the “NYSE”) (including the procedures and mechanics regarding the listing of the Underlying Securities (as defined below) on such exchange) or other events beyond the Company’s control and that such delay will
not be a default under this Agreement so long as (i) the Company is using its reasonable best efforts to effect the issuance of one or more global notes representing the New Notes and (ii) such delay is no longer than five business days.
For the avoidance of doubt, in the event of any delay in the Closing pursuant to the prior sentence, the Holders shall not be required to deliver the Exchanged Notes until the Closing occurs. The cancellation of the Exchanged Notes and the delivery
of the Holder New Notes shall be effected via DTC’s Deposits and Withdrawal at Custodian (“DWAC”) program pursuant to the instructions provided by the Undersigned set forth in Exhibit C hereto, which the Undersigned
agrees to provide no later than the business day immediately following the date of this Agreement. The Holder New Notes will not be delivered until a valid DWAC withdrawal of the Exchanged Notes has been received and accepted by the Trustee. If the
Closing does not occur, any Exchanged Notes submitted for withdrawal through DWAC will be returned to the DTC participant that submitted the withdrawal instruction in accordance with the procedures of DTC. Each Holder acknowledges that each DWAC
withdrawal must be posted on the Closing Date and that if it is posted before the Closing Date, then it will expire unaccepted and must be resubmitted on the Closing Date. 

Article II 

Covenants, Representations and Warranties of the Holders 

Each Holder (and where specified below, the Undersigned) hereby covenants as follows, and makes the following representations and warranties
(severally and not jointly), each of which is and shall be true and correct on the date hereof and at the Closing, to the Company and J.P. Morgan Securities LLC (“J.P. Morgan”), and all such covenants, representations and warranties
shall survive the Closing; provided, however, that any representation and warranty in this Article II that speaks of a specified date shall be true and correct as of that date only. 

Section 2.1 Power and Authorization. Such Holder and the Undersigned is duly organized, validly
existing and in good standing under the laws of its jurisdiction of formation, and the Undersigned has the power, authority and capacity to execute and deliver this Agreement, to perform its obligations hereunder, and to consummate the Transactions,
in each case on behalf of itself and each Account, as applicable. If the Undersigned is executing this Agreement on behalf of Accounts, (a) the Undersigned has all requisite discretionary and contractual authority to enter into this Agreement
on behalf of, and bind, each Account, (b) Exhibit A hereto is a true, correct and complete list of (i) the name of each Account and (ii) the principal amount of such Account’s Exchanged Notes and (c) the Undersigned
agrees with the amount of the principal amount of the Holder New Notes to be issued to such Account in respect of its Exchanged Notes. 

Section 2.2 Valid and Enforceable Agreement; No Violations. This Agreement has been duly executed and
delivered by the Undersigned and constitutes a legal, valid and binding obligation of the Undersigned and such Holder, enforceable against the Undersigned and such Holder in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally or by equitable principles relating to enforceability (collectively, the “Enforceability Exceptions”). The execution and delivery of this
Agreement and consummation of the Transactions will not violate, conflict with, or result in, a breach of or default under (i) the Undersigned’s or the such Holder’s organizational documents (or any similar documents governing each
Account), (ii) any agreement or instrument to which the Undersigned or such Holder is a party or by which the Undersigned or such Holder or any of their respective assets are bound, or (iii) any laws, regulations or governmental or judicial
decrees, injunctions or orders applicable to the Undersigned or such Holder. 












 Section 2.3 Title to the Exchanged Notes. Such
Holder is the sole legal and beneficial owner of the Exchanged Notes set forth opposite its name on Exhibit A hereto (or, if there are no Accounts, the Undersigned is the sole legal and beneficial owner of the Exchanged Notes). Such Holder
has good, valid and marketable title to its Exchanged Notes, free and clear of any Liens (other than pledges or security interests that such Holder may have created in favor of a prime broker under and in accordance with its prime brokerage
agreement with such broker). Such Holder has not, in whole or in part, except as described in the preceding sentence, (a) assigned, transferred, hypothecated, pledged, exchanged or otherwise disposed of any of its Exchanged Notes or its rights,
title or interest in and to its Exchanged Notes or (b) given any person or entity (other than the Undersigned) any transfer order, power of attorney or other authority of any nature whatsoever with respect to its Exchanged Notes. Upon such
Holder’s delivery of its Exchanged Notes to the Company pursuant to the Transactions, such Exchanged Notes shall be free and clear of all Liens created by such Holder or any other person acting for such Holder. 

Section 2.4 Qualified Institutional Buyer. Such Holder is (a) an “accredited investor”
within the meaning of Rule 501(a)(1), (2), (3) or (7) under the United States Securities Act of 1933, as amended (the “Securities Act”), capable of evaluating investment risks independently, both in general and with regard to
all transactions and investment strategies involving a security or securities, including such Holder’s participation in the Transactions, as well as (b) a “qualified institutional buyer” within the meaning of Rule 144A
promulgated under the Securities Act. Such Holder is acquiring the Holder New Notes solely for its own account, for investment purposes, and not with a view to, or for resale in connection with, any distribution of the Holder New Notes in a manner
that would violate the registration requirements of the Securities Act. 
 Section 2.5 No Affiliates;
Holding Period. Neither the Undersigned nor such Holder is, as of the date of this Agreement, or, as of the Closing Date, will be, and neither of them will be at any time during the three months preceding the date of this Agreement or the
Closing Date, a director, officer or other “affiliate” within the meaning of Rule 144 promulgated under the Securities Act (an “Affiliate”) of the Company. Such Holder has either held its Old Notes for at least one year or
acquired its Old Notes from a person who was not, at the time of such acquisition, an Affiliate of the Company and, as a result of tacking the holding period of prior non-Affiliate purchasers, has held its Old
Notes for at least one year, in each case within the meaning of Rule 144(d) under the Securities Act. 

Section 2.6 No Illegal Transactions. Neither the Undersigned nor such Holder has, directly or
indirectly, and no person acting on behalf of or pursuant to any understanding with it has, disclosed to a third party any information regarding the Transactions, nor engaged in any transactions in the securities of the Company (including, without
limitation, any Short Sales (as defined below) involving any of the Company’s securities) since the time that the Undersigned was first contacted by any of the Company, J.P. Morgan or any other person regarding the Transactions, this Agreement
or an investment in the Holder New Notes or the Company. Each of the Undersigned and such Holder covenants that neither it nor any person acting on its behalf or pursuant to any understanding with it will disclose to a third party any information
regarding the Transactions or engage, directly or indirectly, in any transactions in the securities of the Company (including Short Sales) prior to the Release Time (as defined below). “Short Sales” include, without limitation, all
“short sales” as defined in Rule 200 of Regulation SHO promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”) and all types of direct and indirect stock pledges, forward sale contracts, options, puts,
calls, short sales, swaps, derivatives and similar arrangements (including on a total-return basis), and sales and other transactions through non-U.S. broker-dealers or foreign-regulated brokers. Solely for
purposes of this Section 2.6, subject to the Undersigned’s and such Holder’s compliance with their respective obligations under the U.S. federal securities laws and the Undersigned’s and such Holder’s
respective internal policies, (a) the terms “Undersigned” and “Holder” shall not be deemed to include any employees, subsidiaries, desks, groups or Affiliates of the Undersigned or such Holder that are effectively walled off
by appropriate “Fire Wall” information barriers approved by the Undersigned’s or such Holder’s respective legal or 












 
compliance department (and, thus, such walled-off parties have not been privy to any information concerning the Transactions), and (b) the foregoing
representations and covenants of this Section 2.6 shall not apply to any transaction by or on behalf of an Account that was effected without the advice or participation of, or such Account’s receipt of information
regarding the Transactions provided by, the Undersigned or the applicable Holder. 
 Section 2.7 Adequate
Information; No Reliance. The Undersigned is a registered investment adviser with the Securities and Exchange Commission (the “SEC”) acting on behalf of itself and, as applicable, the Accounts that are Holders who are its
investment advisory clients. The Undersigned acknowledges and agrees on behalf of itself and, as applicable, such Holder that (a) the Undersigned has been furnished with all materials it considers relevant to making an investment decision to
enter into the Transactions and has had the opportunity to review the Company’s filings and submissions with the SEC, including, without limitation, all information filed or furnished pursuant to the Exchange Act, (b) the Undersigned has
had a full opportunity to ask questions of the Company concerning the Company, its business, operations, financial performance, financial condition and prospects and the terms and conditions of the Transactions, (c) the Undersigned and such
Holder have had the opportunity to consult with their respective accounting, tax, financial and legal advisors to be able to evaluate the risks and consequences involved in the Transactions and to make an informed investment decision with respect to
such Transactions, including, if applicable, the consequences to such Holder of the issuance of the Holder New Notes with significant original issue discount for U.S. federal income tax purposes, (d) neither the Company nor J.P. Morgan nor any
of their respective Affiliates or representatives is acting as a fiduciary or financial or investment advisor to the Undersigned or such Holder, (e) neither the Undersigned nor such Holder is relying, and none of them have relied, upon any
statement, advice (whether accounting, tax, financial, legal or other), representation or warranty made by the Company, J.P. Morgan or any of their respective Affiliates or representatives, except, in the case of the Company (and as to which neither
J.P. Morgan nor any of its Affiliates or representatives makes any representation), for (i) the publicly available filings and submissions made by the Company with the SEC under the Exchange Act and (ii) the representations and warranties
made by the Company in this Agreement. Each of the Undersigned and such Holder is able to fend for itself in the Transactions; has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of
its prospective investment in the Holder New Notes; has the ability to bear the economic risks of its prospective investment and can afford the complete loss of such investment; and acknowledges that investment in the Holder New Notes involves a
high degree of risk. Each of the Undersigned and such Holder has had a sufficient amount of time to consider whether to participate in the Transactions, and neither the Company nor J.P. Morgan, nor any of their respective Affiliates or agents, has
placed any pressure on the Undersigned or any Holder to respond to the opportunity to participate in the Transactions and (f) J.P. Morgan shall have no liability or obligation (including, without limitation, for or with respect to any losses,
claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements incurred by such Holder, the Company or any other person or entity), whether in contract, tort or otherwise, to such Holder, or to any person
claiming through such Holder, in respect of the Transactions. 
 Section 2.8 No Public Market. The
Undersigned acknowledges and agrees, on behalf of itself and such Holder, that no public market exists for the New Notes, and that there is no assurance that a public market will ever develop for the New Notes. 

Section 2.9 Taxpayer Information. The Undersigned agrees that it will obtain from such Holder and
deliver to the Company a complete and accurate IRS Form W-9 or IRS Form W-8BEN, W-8BEN E or
W-8ECI, as appropriate. 
 Section 2.10 Further Action. Each
of the Undersigned and such Holder agrees that it will, upon request, execute and deliver any additional documents reasonably deemed by the Company or the Trustee to be necessary or desirable to complete the Transactions. 












 Section 2.11. Placement Agent. The Undersigned
acknowledges that it and such Holder understand that the Company intends to pay J.P. Morgan a fee in respect of the Transactions. 

Section 2.12. Ownership. Such Holder does not have an ownership interest equal to or greater than
either 5% of the number of the Company’s common shares or 5% of the voting power outstanding of the Company, in each case, before the initial issuance of the securities issued in the Transactions. 

Article III 

Covenants, Representations and Warranties of the Company 

The Company hereby covenants as follows, and makes the following representations and warranties, each of which is and shall be true and
correct on the date hereof and at the Closing, to the Holders and J.P. Morgan, and all such covenants, representations and warranties shall survive the Closing; provided, however, that any representation and warranty in this Article
III that speaks of a specified date shall be true and correct as of that date only. 
 Section 3.1
Organization and Good Standing. The Company and each of its significant subsidiaries (as such term is defined in Rule 1-02 of Regulation S-X) has been duly
organized or formed, as applicable, and are validly existing and in good standing under the laws of their respective jurisdictions of organization or formation, as applicable, are duly qualified to do business and are in good standing in each
jurisdiction in which their respective ownership or lease of property or the conduct of their respective businesses requires such qualification, and have all power and authority necessary to own or hold their respective properties and to conduct the
businesses in which they are engaged, except where the failure to be so qualified or in good standing or have such power or authority would not, individually or in the aggregate, have a material adverse effect on the business, properties,
management, financial position, shareholders’ equity, results of operations or prospects of the Company and its subsidiaries taken as a whole or on the performance by the Company of its obligations under the Transaction Documents (as defined
below) (a “Material Adverse Effect”). The Company does not own or control, directly or indirectly, any corporation, association or other entity other than the subsidiaries listed in Exhibit 21.1 to the Company’s Annual Report
on Form 10-K for the year ended December 31, 2019. 
 Section 3.2
Due Authorization. The Company has all requisite corporate power and authority to execute and deliver this Agreement, the Supplemental Indenture and the Holder New Notes (collectively, together with the Base Indenture, the
“Transaction Documents”) and to perform its obligations hereunder and thereunder; and all action required to be taken for the due and proper authorization, execution and delivery by it of each of the Transaction Documents and the
consummation by it of the transactions contemplated thereby has been duly and validly taken. 
 Section 3.3
The Indenture. The Supplemental Indenture has been duly authorized by the Company. When the Supplemental Indenture has been duly executed and delivered in accordance with its terms by each of the parties thereto, it will
constitute a valid and legally binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to the Enforceability Exceptions. 

Section 3.4 Exchange Agreement. This Agreement has been duly authorized, executed and delivered
by the Company and constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as enforceability may be limited by the Enforceability Exceptions. 












 Section 3.5 The Holder New Notes. The Holder
New Notes have been duly authorized by the Company and, when duly executed, authenticated, issued and delivered as provided in the Indenture and exchanged for as provided herein, will be duly and validly issued and outstanding and will constitute
valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the Enforceability Exceptions, and will be entitled to the benefits of the Indenture. Assuming the accuracy of the
Undersigned’s and each Holder’s representations and warranties hereunder, the Holder New Notes (a) will be issued in the Transactions exempt from the registration requirements of the Securities Act pursuant to Section 4(a)(2) of
the Securities Act, (b) will, at the Closing, be free of any restrictions on resale by such Holder pursuant to Rule 144 promulgated under the Securities Act, and (c) will be issued in compliance with all applicable state and federal laws
concerning the issuance of the Holder New Notes. 
 Section 3.6 The Underlying Securities.
Upon issuance and delivery of the Holder New Notes in accordance with this Agreement and the Indenture, the Holder New Notes will be convertible into cash, common shares, without par value, of the Company (the “Common Shares”),
or a combination of cash and Common Shares (all such Common Shares issuable upon conversion of the New Notes, the “Underlying Securities”) in accordance with the terms of the New Notes and the Indenture; the maximum number of
Underlying Securities initially issuable upon conversion of the New Notes (including the maximum number of Underlying Securities that may be issued upon any conversions of New Notes in connection with any “Make-Whole Fundamental Change”
(as such term is defined in the Indenture), assuming the Company elects to issue and deliver solely Common Shares in respect of all such conversions (the “Maximum Number of Underlying Securities”)) has been duly authorized
and reserved for issuance upon the conversion of the New Notes and, when issued upon conversion of the New Notes in accordance with the terms of the New Notes and the Indenture, such Maximum Number of Underlying Securities will be validly issued,
fully paid and non-assessable, and the issuance of such Maximum Number of Underlying Securities will not be subject to any preemptive or similar rights. 

Section 3.7 No Violation or Default. Neither the Company nor any of its subsidiaries is (i) in
violation of its charter or by-laws or similar organizational documents; (ii) in default, and no event has occurred that, with notice or lapse of time or both, would constitute such a default, in the due
performance or observance of any term, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or
any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject; or (iii) in violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator
or governmental or regulatory authority having jurisdiction over the Company or any of its subsidiaries, except, in the case of clauses (ii) and (iii) above, for any such default or violation that would not, individually or in the aggregate, be
reasonably expected to have a Material Adverse Effect. 
 Section 3.8 No Conflicts. The execution,
delivery and performance by the Company of each of the Transaction Documents, the issuance and sale of the Holder New Notes (including the issuance of any Underlying Securities upon conversion thereof) and the consummation of the transactions
contemplated by the Transaction Documents will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or
encumbrance upon any property or assets of the Company or any of its subsidiaries pursuant to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by
which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject, (ii) result in any violation of the provisions of the charter or by-laws or similar organizational documents of the Company or any of its subsidiaries or (iii) result in the violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator
or governmental or regulatory authority, except, in the case of clauses (i) and (iii) above, for any such conflict, breach, violation or default that would not, individually or in the aggregate, be reasonably expected to have a Material Adverse
Effect. 












 Section 3.9 No Consents Required. No consent,
approval, authorization, order, license, registration or qualification of or with any court or arbitrator or governmental or regulatory authority is required for the execution, delivery and performance by the Company of each of the Transaction
Documents, the issuance and sale of the Holder New Notes (including the issuance of any Underlying Securities upon conversion thereof) and the consummation of the transactions contemplated by the Transaction Documents, except as may be required
under any state or federal securities laws or that have been or will be obtained. 
 Section 3.10 Legal
Proceedings. Except as described in the Company’s filings and submissions with the SEC, including, without limitation, all information filed or furnished pursuant to the Exchange Act, there are no legal, governmental or regulatory
investigations, actions, suits or proceedings pending to which the Company or any of its subsidiaries is or may be a party or to which any property of the Company or any of its subsidiaries is or may be the subject that, individually or in the
aggregate, if determined adversely to the Company or any of its subsidiaries, would reasonably be expected to have a Material Adverse Effect; no such investigations, actions, suits or proceedings are threatened or, to the knowledge of the Company,
contemplated by any governmental or regulatory authority or threatened by others. 
 Section 3.11 Listing
Approval. The Company will reserve and keep available at all times, free of pre-emptive rights, a number of Common Shares equal to the Maximum Number of Underlying Securities for the purpose of
enabling the Company to satisfy all obligations to issue Underlying Securities upon conversion of the New Notes. The Company will list on or prior to the Closing Date such number of Common Shares equal to the Maximum Number of Underlying Securities
on the NYSE and will use its commercially reasonable efforts to maintain the listing of such number of Common Shares on the NYSE. 

Section 3.12 Disclosure. No later than 8:30 a.m. on the first business day following the date of this Agreement (the
“Release Time”), the Company shall issue a publicly available press release or file with the SEC a Current Report on Form 8-K disclosing the material terms of the Transactions and certain
information concerning the Company (to the extent not previously publicly disclosed). Without the prior written consent of the Undersigned, the Company shall not disclose the name of the Undersigned or any Holder in any filing or announcement,
unless such disclosure is required by applicable law, rule, regulation or legal process based on advice of counsel. The Company represents that, as of the Release Time, none of the information provided by or on behalf of the Company to the
Undersigned or any Holder in connection with the Transactions will constitute material non-public information. 

Section 3.13 Investment Company. The Company is not and, after giving effect to the Transactions, will not be an
“investment company” within the meaning of the Investment Company Act of 1940, as amended, and the rules and regulations of the SEC thereunder.

is unlimited. The Notes may be issued in one or more Series. All Notes of a Series shall be identical except as may be set forth in a Board Resolution, a supplemental indenture or an Officer’s Certificate detailing the adoption of the terms
thereof pursuant to the authority granted under a Board Resolution. In the case of Notes of a Series to be issued from time to time, the Board Resolution, Officer’s Certificate or supplemental indenture detailing the adoption of the terms
thereof pursuant to authority granted under a Board Resolution may provide for the method by which specified terms (such as interest rate, maturity date, record date or date from which interest shall accrue) are to be determined. Notes may differ

 (d) the date or dates on which the principal of the Notes of the Series is payable; 

(e) the rate or rates (which may be fixed or variable) per annum or, if applicable, the method used to determine such rate or rates (including,
but not limited to, any commodity, commodity index, stock exchange index or financial index) at which the Notes of the Series shall bear interest, if any, the date or dates from which such interest, if any, shall accrue, the date or dates on which
such interest, if any, shall commence and be payable and any regular record date for the interest payable on any interest payment date; 

(f) the place or places where the principal of, premium and interest, if any, on the Notes of the Series shall be payable, where the Notes of
such Series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Notes of such Series and this Indenture may be served, and the method of such payment, if by wire

of $1,000 in excess thereof; 
 (k) the forms of the Notes of the Series in bearer or fully registered form (and, if in fully registered
form, whether the Notes will be issuable as Global Notes);

 (s) any depositaries, interest rate calculation agents, exchange rate
calculation agents or other agents with respect to Notes of such Series if other than those appointed herein. 
 All Notes of any one Series
need not be issued at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so provided by or pursuant to the Board Resolution, supplemental indenture hereto or Officer’s Certificate referred to
above, and, unless otherwise provided, a Series may be reopened, without the consent of the Holders, for issuances of additional Notes of such Series; provided, however, that if such additional Notes are not fungible with the Notes of
such Series for U.S. federal income tax purposes, the additional Notes will have a separate CUSIP number. No Board Resolution or Officer’s Certificate may affect the Trustee’s own rights, duties or immunities under this Indenture or
otherwise with respect to any series of Notes except as it may agree in writing. 
 Section 2.03 Execution and Authentication.

 One Officer shall sign the Notes for the Company by manual or facsimile signature. If an Officer whose signature is on a Note no
longer holds that office at the time such Note is authenticated, such Note shall nevertheless be valid. 
 A Note shall not be valid until
authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note, as applicable, has been authenticated under this Indenture. 

The Trustee shall, upon a written order of the Company signed by one Officer (an “Authentication Order”), authenticate Notes
for original issue in accordance with this Indenture. The Notes shall be dated their date of authentication. 
 The Trustee may appoint an
authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such
agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company. 
 At any time and from
time to time after the execution and delivery of this Indenture, the Company may deliver Notes of any Series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes,
and the Trustee in accordance with the Company Order will authenticate and deliver such Notes. In authenticating such Notes, and accepting the additional responsibilities under this Indenture in relation to such Notes, the Trustee shall receive, and
(subject to Section 7.01) will be fully protected in relying upon, an Opinion of Counsel stating: 
 (a) that such form has been
established in conformity with the provisions of this Indenture; 
 (b) that such terms have been established in conformity with the
provisions of this Indenture; and 
 (c) that this Indenture and such Notes, when authenticated and delivered by the Trustee and, with
respect to the Notes, when issued by the Company, in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Company enforceable in accordance with their terms, except as
the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium, or other laws relating to or affecting creditors’ rights and by general principles of equity. 

Section 2.04 Registrar and Paying Agent. 

The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange
(“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register with respect to each Series of the Notes and of their transfer and exchange. The


  
 8 













 
Company may appoint one or more co-registrars and one or more additional paying agents or change the office of such Registrar or Paying Agent. The term “Registrar” includes any
co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder; however, the Company shall maintain a Paying Agent in each place of payment
for the Notes of each Series. The Company shall promptly notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the
Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 
 The Company initially appoints
the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes. The Company shall be responsible for making calculations called for under the Notes and this Indenture, including, but not limited to,
determination of interest, additional amounts, redemption price, premium, if any, and any other amounts payable on the Notes. The Company will make the calculations in good faith and, absent manifest error, its calculations will be final and binding
on the Holders. The Company will provide a schedule of its calculations to the Trustee when requested by the Trustee in writing, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s calculations without independent
verification. The Trustee shall forward the Company’s calculations to any Holder of the Notes upon the written request of such Holder. 

Section 2.05 Paying Agent to Hold Money in Trust. 

The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust, for the
benefit of Holders of any Series of Notes, or the Trustee, all money held by the Paying Agent for the payment of principal or interest on the Series of Notes, and shall notify the Trustee of any default by the Company in making any such payment.
While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. All payments to a Paying Agent on any
Notes which remain unclaimed for a period of two years after such payment was due shall be repaid to the Company. Thereafter, the Holder may look only to the Company for repayment. Upon payment over to the Trustee, or to the Company, as the case may
be, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of Holders of
any Series of Notes all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes. 

Section 2.06 Holder Lists. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
Holders of each Series of Notes and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee, at least seven Business Days before each interest payment date and at such other
times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of each Series of Notes and the Company shall otherwise comply with TIA
Section 312(a). 
 Section 2.07 Transfer and Exchange. 

Notes may be transferred or exchanged at the office of the Registrar or co-registrar designated by the Company. Where Notes of a Series are
presented to the Registrar or a co-registrar with a request to register a transfer or to exchange them for an equal principal amount of Notes of the same Series, the Registrar shall register the transfer or make the exchange if its requirements for
such transactions are met. To permit registrations of transfers and exchanges, the Trustee shall authenticate Notes at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange (except as otherwise
expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar governmental charge payable
upon exchanges pursuant to Sections 2.11, 3.06 or 9.05). 

  
 9 













 Neither the Company nor the Registrar shall be required (a) to issue, register the
transfer of, or exchange Notes of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Notes of that Series selected for redemption and ending at the close of
business on the day of such mailing, or (b) to register the transfer of or exchange Notes of any Series selected, called or being called for redemption as a whole or a portion thereof, except the unredeemed portion of Notes being redeemed in
part. 
 The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other than to
require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to
form with the express requirements hereof. 
 Section 2.08 Replacement Notes. 

If any mutilated Note is surrendered to the Trustee, or if the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order together with such indemnity or security sufficient in the judgment of the Trustee and the Company to protect the Company, the
Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced, shall authenticate a replacement Note of the same Series if the Trustee’s requirements are met. The Company may charge for its
expenses in replacing a Note. 
 Every replacement Note of any Series is an additional obligation of the Company and shall be entitled to
all of the benefits of this Indenture equally and proportionately with all other Notes of that Series duly issued hereunder. 
 Section 2.09
Outstanding Notes. 
 The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth
in Section 2.10 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 

If a Note is replaced pursuant to Section 2.08 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Note is held by a bona fide purchaser. 
 If the principal amount of any Note is considered paid under Section 4.01
hereof, it ceases to be outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. 

Section 2.10 Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes of a Series have concurred in any direction, waiver or consent,
Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes of a Series that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. 

  
 10 













 Section 2.11 Temporary Notes. 

Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee.
Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. 

Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. 

Section 2.12 Cancellation. 

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation. The Company may not issue new
Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. Cancelled Notes shall be disposed of by the Trustee pursuant to its standard procedures and, upon request by the Company, the Trustee shall deliver
a certificate or other evidence of such disposition. 
 Section 2.13 Defaulted Interest. 

If the Company defaults in a payment of interest on a Series of Notes, it shall pay the defaulted interest in any lawful manner plus, to the
extent lawful, interest payable on the defaulted interest, to the Persons who are Holders of the Series on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the
Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided that no such
special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at
the expense of the Company) shall mail or cause to be mailed (or, in the case of the Depositary with respect to any Global Note, sent electronically) to Holders a notice that states the special record date, the related payment date and the amount of
such interest to be paid. 
 Section 2.14 Global Notes. 

(a) Terms of Notes. A Board Resolution, a supplemental indenture hereto, or an Officer’s Certificate shall establish whether the
Notes of a Series shall be issued in whole or in part in the form of one or more Global Notes and shall name the Depositary for such Global Note or Notes. Except as provided herein, each Global Note shall be (i) registered in the name of the
Depositary, (ii) deposited with the Depositary or its nominee, and (iii) bear the legend indicated in Section 2.14(c). 
 (b)
Transfer and Exchange. Notwithstanding any provisions to the contrary contained in Section 2.07 and in addition thereto, any Global Note shall be exchangeable pursuant to Section 2.07 for Notes registered in the names of Holders
other than the Depositary for such Note or its nominee only if (i) such Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Note or if at any time such Depositary ceases to be a clearing
agency registered under the Exchange Act, and, in either case, the Company fails to appoint a successor Depositary registered as a clearing agency under the Exchange Act within 90 days of such event, (ii) the Company executes and delivers to
the Trustee an Officer’s Certificate to the effect that such Global Note shall be so exchangeable or (iii) an Event of Default with respect to the Notes represented by such Global Note shall have happened and be continuing. Any Global Note
that is exchangeable pursuant to the preceding sentence shall be exchangeable for Notes registered in such names as the Depositary shall direct in writing in an aggregate principal amount equal to the principal amount of the Global Note with like
tenor and terms. 
 Except as provided in this Section 2.14(b), a Global Note may not be transferred except as a whole by the
Depositary with respect to such Global Note to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by the Depositary, or any such nominee to a successor Depositary or a nominee of
such a successor Depositary. 

  
 11 













 (c) Legend. Any Global Note issued hereunder shall bear a legend in substantially the
following form: 
 “This Note is a Global Note within the meaning of the Indenture hereinafter referred to and is
registered in the name of the Depositary or a nominee of the Depositary. This Note is exchangeable for Notes registered in the name of a person other than the Depositary or its nominee only in the limited circumstances described in the Indenture,
and may not be transferred except as a whole by the Depositary to a nominee of the Depositary, 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 a successor Depositary.” 
 (d) Acts of Holders. The Depositary, as a Holder, may appoint agents and
otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under this Indenture. The record date for purposes of determining the
identity of Holders entitled to vote or consent to any action by vote or consent authorized or permitted under this Indenture may be determined as provided for in Section 316(c) of the TIA. 

(e) Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.02,
payment of the principal of and interest, if any, on any Global Note shall be made to the Holder thereof. Prior to due presentment of a Note for registration of transfer, the Company, the Trustee, and any agent of the Company or the Trustee may
treat the Person in whose name such Note is registered as the owner of such Note at the close of business on the regular record date for the purpose of receiving payment of principal of and any premium and (subject to Section 2.13) any interest
on such Note and for all other purposes whatsoever, whether or not such Note shall be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee will be affected by notice to the contrary. 

(f) Consents, Declaration and Directions. Except as provided in Section 2.14(e), the Company, the Trustee and any Agent shall treat
a person as the Holder of such principal amount of outstanding Notes of such Series represented by a Global Note as shall be specified in a written statement of the Depositary with respect to such Global Note, for purposes of obtaining any consents,
declarations, waivers or directions required to be given by the Holders pursuant to this Indenture. 
 (g) Responsibility of Trustee or
Agents. Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary. The Company has entered into a letter of representations with the Depositary in the form provided by the Depositary and
the Trustee and each Agent is hereby authorized to act in accordance with such letter and the Applicable Procedures. 
 Section 2.15 CUSIP
Number. 
 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 notices as a convenience to Holders; provided that the Trustee shall have no liability for any defect in the CUSIP numbers as they appear on any Note, notice or elsewhere, and 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 as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Notes, and any such
notice shall not be affected by any defect in or the omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP numbers. 

ARTICLE 3 
 REDEMPTION
AND PREPAYMENT 
 Section 3.01 Notice to Trustee. 

The Company may, with respect to any Series of Notes, reserve the right to redeem and pay the Series of Notes or may covenant to redeem and pay
the Series of Notes or any part thereof prior to the Stated Maturity thereof at such time and on such terms as provided for in such Notes. If a Series of Notes is redeemable and the Company 

  
 12 













 
wants or is obligated to redeem prior to the Stated Maturity thereof all or part of the Series of Notes pursuant to the terms of such Notes, it shall notify the Trustee in writing of the
redemption date and the principal amount of Series of Notes to be redeemed. The Company shall give the notice at least 15 days prior to the mailing or sending of notice of redemption to the Holders of the Notes to be redeemed (or such shorter notice
as may be acceptable to the Trustee). 
 Section 3.02 Selection of Notes to Be Redeemed. 

If less than all of the Notes of a Series are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the
Notes of a Series to be redeemed or purchased among the Holders of the Notes (a) in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, (b) if the Notes are not so
listed, on a pro rata basis, by lot or in accordance with the applicable procedures of the Depositary. 
 The Trustee shall promptly
notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes of a Series and portions of them selected shall be in amounts of
$2,000 or whole multiples of $1,000, or with respect to Notes of any Series issuable in other denominations pursuant to Section 2.02(j), the minimum principal denomination for each Series and integral multiples thereof. Except as provided in
the preceding sentence, provisions of this Indenture that apply to Notes of a Series called for redemption or repurchase also apply to portions of Notes of a Series called for redemption or repurchase. 

Section 3.03 Notice of Redemption. 

Unless otherwise indicated for a particular Series by Board Resolution, a supplemental indenture hereto or an Officer’s Certificate, at
least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, or, in the case of the Depositary with respect to any Global Note, sent electronically, a notice of redemption to
each Holder whose Notes are to be redeemed at its registered address. 
 The notice shall identify the Notes of the Series to be redeemed
and shall state: 
 (1) the redemption date; 

(2) the redemption price (or manner of calculation if not then known); 

(3) the name and address of the Paying Agent; 

(4) that Notes of the Series called for redemption must be surrendered to the Paying Agent to collect the redemption price;

 (5) that interest on Notes of the Series called for redemption ceases to accrue on and after the redemption date; 

(6) the CUSIP number, if any, provided that no representation is made as to the correctness or accuracy of the CUSIP number, if
any, listed in such notice or printed on the Notes; 
 (7) the conditions precedent, if any, to the redemption; and 

(8) any other information as may be required by the terms of the particular Series of the Notes or the Notes of a Series being
redeemed. 
 At the Company’s request, and upon receipt of an Officer’s Certificate complying with Section 11.04 hereof at
least 15 days prior to the date notice is to be given (unless a shorter period shall be satisfactory to the Trustee), together with the notice to be given setting forth the information to be stated therein as provided in the preceding
paragraph, the Trustee shall give the notice of redemption in the Company’s name and at its expense. 

  
 13 













 Section 3.04 Effect of Notice of Redemption. 

Once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable
on the redemption date at the redemption price. Unless otherwise indicated for a particular Series by Board Resolution, a supplemental indenture hereto or an Officer’s Certificate, a notice of redemption may not be conditional. 

Section 3.05 Deposit of Redemption Price. 

At least one Business Day prior to the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to
pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. 
 If the Company complies with the
provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If any Note called for redemption shall not be so paid upon surrender for redemption
because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid
principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 
 Section 3.06 Notes Redeemed in Part.

 Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon the Company’s written request, the Trustee
shall authenticate for the Holder, or transfer by book-entry, at the expense of the Company, a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 

No Notes of $2,000 or less can be redeemed in part (or with respect to Notes of any Series issuable in other denominations pursuant to
Section 2.02(j), the minimum denomination for each Series and integral multiples thereof). 
 ARTICLE 4

Notes that it will pay or cause to be paid the principal of, premium, if any, and interest on such Series of Notes on the dates and in the manner provided in such Notes. Principal, premium, if any, and interest on any Series of Notes will be
considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by the Company in immediately available funds and designated for and

 Section 4.02 Maintenance of Office or Agency. 

The Company covenants and agrees for the benefit of the Holders of each Series of Notes that it will maintain an office or agency (which may be
an office of the Trustee for such Notes or an affiliate of the Trustee, Registrar for such Notes or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in
respect of such Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee for such Notes of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain
any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

  
 14 













 With respect to each Series of Notes, the Company hereby designates the Corporate Trust
Office of the Trustee as one such office or agency of the Company in accordance with Section 2.04. 
 Section 4.03 Reports.

 The Company will at all times comply with TIA § 314(a). Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with
any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). 
 Section 4.04
Compliance Certificate. 
 The Company and each guarantor of any Series of Notes (to the extent that such guarantor is so
required under the TIA) shall deliver to the Trustee with respect to such Series, within 120 days after the end of each fiscal year, an Officer’s Certificate signed by the principal executive officer, the principal financial officer or the
principal accounting officer, stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officer with a view to determining whether the Company has
kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to the Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and
every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such
Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason

Section 4.05 Taxes. 

The Company will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental
levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. 

Section 4.06 Stay, Extension and Usury Laws. 

The Company covenants (to the extent that it may lawfully do so) that it will not, and each guarantor of such Notes will 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 wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture;
and the Company and each of such guarantors (to the extent that it may lawfully do so), as applicable, 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 for such Notes, but will suffer and permit the execution of every such power as though no such law has been enacted. 

Section 4.07 Corporate Existence. 

Subject to Articles 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect: 

(a) the corporate, partnership or other existence of itself and each of its Subsidiaries, in accordance with the respective organizational
documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and 

  
 15 













 (b) the rights (charter and statutory), licenses and franchises of the Company and
its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if an Officer shall determine
that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. 

ARTICLE 5

(a) merge or consolidate with or into another Person or Persons; or 

(b) sell, convey, transfer, lease or otherwise dispose of all or substantially all of the properties or assets of the Company and its

into which the Company is merged or formed by such consolidation or to which such sale, conveyance, transfer, lease or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such merger, consolidation,

DEFAULTS AND REMEDIES 

Section 6.01 Events of Default. 

“Event of Default,” wherever used herein with respect to Notes of any Series, means any one of the following events, unless in
the establishing Board Resolution, supplemental indenture or Officer’s Certificate, it is provided that such Series shall not have the benefit of said Event of Default: 

(a) default in the payment of any interest on any Note of that Series when it becomes due and payable, and continuance of such default for a
period of 30 days; or 
 (b) default in payment when due of the principal of, or premium, if any, on any Note of that Series; or 

(c) failure on the part of the Company to comply with Article 5; 

(d) default in the performance or breach of any covenant or warranty of the Company in this Indenture or in any Board Resolution, supplemental
indenture or Officer’s Certificate with respect to such Series (other than a covenant or warranty that has been included in this Indenture or a Board Resolution, supplemental indenture or Officer’s Certificate solely for the benefit of
Series of Notes other than that Series), which default continues uncured for a period of 90 days after (i) the Company receives written notice from the Trustee for such Notes or (ii) the Company and the Trustee receive written notice from
Holders of not less than 25% in aggregate principal amount of Notes of that Series outstanding; or 
 (e) the Company: 

(1) commences a voluntary case in bankruptcy, 

(2) consents to the entry of an order for relief against it in an involuntary bankruptcy case, 

(3) applies for or consents to the appointment of any custodian, receiver, trustee, conservator, liquidator, rehabilitator or
similar officer of it or for all or substantially all of any of its property, 
 (4) makes a general assignment for the
benefit of its creditors, or 
 (5) generally is unable to pay its debts as they become due; 

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

(1) is for relief against the Company; 

(2) appoints a custodian of the Company or for all or substantially all of the property of the Company; or

and the order or decree remains unstayed and in effect for 60 consecutive days; or 

(g) any other Event of Default provided with respect to Notes of that Series, which is specified in a Board Resolution, a supplemental
indenture hereto or an Officer’s Certificate, in accordance with Section 2.02. 
 The Company shall deliver to the Trustee
promptly after the occurrence thereof, written notice in the form of an Officer’s Certificate of any event which with the giving of notice and the lapse of time would become an Event of Default under clause (c), (d) or (g), its status and
what action the Company is taking or proposes to take with respect thereto.

 Section 6.02 Acceleration. 

If an Event of Default with respect to Notes of any Series at the time outstanding occurs and is continuing (other than an Event of Default
referred to in Section 6.01(e) or (f)) then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes of that Series may declare the principal amount (or, if any Notes of that
Series are Discount Notes, such portion of the principal amount as may be specified in the terms of such Notes) of and accrued and unpaid interest, if any, on all of the Notes of that Series to be due and payable immediately, by a notice in writing
to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) and accrued and unpaid interest, if any, shall become immediately due and payable. If an Event of Default specified in
Section 6.01(e) or (f) shall occur, the principal amount (or specified amount) of and accrued and unpaid interest, if any, on all outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Holder. 
 At any time after such a declaration of acceleration with respect to any Series has been
made, the Holders of a majority in principal amount of the outstanding Notes of that Series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if the rescission and annulment would not
conflict with any judgment or decree already rendered and if all existing Events of Default with respect to that Series (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or
waived and all sums paid or advanced by the Trustee hereunder and the reasonable compensation expenses and disbursements of the Trustee and its agents and counsel have been paid. 

No such rescission shall affect any subsequent Event of Default or impair any right consequent thereon. 

Section 6.03 Other Remedies. 

If an Event of Default with respect to Notes of any Series at the time outstanding occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal, premium, if any, and interest on such Notes or to enforce the performance of any provision of such Notes or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults. 

Prior to the acceleration of the maturity of the Notes of any Series as provided in Section 6.02, the Holders of a majority in aggregate
principal amount of the Notes of any Series then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes of such Series waive any existing Default or Event of Default with respect to such Series and its consequences
under this Indenture except (i) a continuing Default or Event of Default in the payment of premium or interest on, or the principal of, the Notes of such Series (including in connection with an offer to purchase) or (ii) a Default or Event
of Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected thereby. Upon any such waiver, such Default or Event of 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 shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

Section 6.05 Control by Majority. 

Holders of a majority in aggregate principal amount of the then outstanding Notes of any Series may in writing direct the time, method and
place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it, subject to Section 7.02(f). However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes of such Series (it being understood that the Trustee does not have an affirmative duty to ascertain whether any such directions are
unduly prejudicial to such Holders) or that may involve the Trustee in personal liability. The Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. 

  
 18 













 Section 6.06 Limitation on Suits. 

A Holder of any Series of Notes may pursue a remedy with respect to this Indenture or the Notes only if: 

(a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; 

(b) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes of such Series make a written request to the
Trustee to pursue the remedy; 
 (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee security or
indemnity satisfactory to the Trustee against any loss, liability or expense; 
 (d) the Trustee does not comply with the request within 60
days after receipt of the request and the offer and, if requested, the provision of security or indemnity; and 
 (e) during such 60-day
period the Holders of a majority in aggregate principal amount of the then outstanding Notes of such Series do not give the Trustee a direction inconsistent with the request. 

A Holder of any Series of Notes may not use this Indenture to prejudice the rights of another Holder of Notes or to obtain a preference or
priority over another Holder of Notes. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and
interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired
or affected without the consent of such Holder. 
 Section 6.08 Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01 (a) or (b) hereof occurs and is continuing, the Trustee is authorized to
recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

Section 6.09 Trustee May File Proofs of Claim. 

The Trustee for each Series of Notes is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes of such Series allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Notes of such Series), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder of such Series to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the
Holders of such Series, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in


  
 19 













 
any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders of such Series may be entitled to receive in such proceeding 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 Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding. 
 Section 6.10 Priorities. 

If the Trustee collects any money or property with respect to a Series of Notes pursuant to this Article 6, or, after an Event of Default, any
money or other property distributable in respect of the Company’s obligations under this Indenture, it shall pay out the money or property in the following order: 

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof applicable to the Notes
of such Series, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders of Notes of such Series for amounts due and unpaid on the Notes for principal, premium, if any, and
interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and 

Third: to the Company or to such party as a court of competent jurisdiction shall direct. 

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. 

Section 6.11 Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted
by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note
pursuant to Section 6.07 hereof, or a suit by Holders or group of Holders of more than 10% in principal amount of the then outstanding Notes of any Series. 

Section 6.12 Restoration of Rights and Remedies. 

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee, and the Holders will be restored
severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders will continue as though no such proceeding had been instituted.

(a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this

hereof are specifically required to be furnished to the Trustee to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated
thereon).

investigation. 
 Section 7.03 Individual Rights of Trustee. 

The Trustee and any agent thereof hereunder in their respective individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest as defined in the TIA it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee shall not be deemed to have a
conflicting interest with respect to Notes of any series by virtue of being a trustee under this Indenture with respect to any particular series of Notes. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 

  
 22 













 Section 7.04 Trustee’s Disclaimer. 

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not
be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it will not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other
than its certificate of authentication. Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by any Notes. 

Section 7.05 Notice of Defaults. 

If a Default or Event of Default occurs and is continuing and if it is actually known to the Trustee, the Trustee will circulate to Holders of
Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on, any Note, the Trustee may withhold the notice from
Holders of the Notes if and so long as it in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 

Section 7.06 Reports by Trustee to Holders of the Notes. 

(a) Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain
outstanding, the Trustee will mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit by mail all reports as required by TIA § 313(c). 

(b) A copy of each report at the time of its mailing to the Holders of Notes will be mailed by the Trustee to the Company and filed by the
Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company will promptly notify the Trustee when the Notes are listed on any stock exchange or delisted therefrom. 

Section 7.07 Compensation and Indemnity. 

(a) The Company will pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the
Trustee and the Company may agree from time to time in writing. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly upon request for all
reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

 (b) The Company will indemnify the Trustee, its officers, directors, employees, representatives and agents from and against any and all
losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this
Section 7.07) and defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent
any such loss, liability or expense may be attributable to its negligence or willful misconduct. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not
relieve the Company of its obligations hereunder. The Company will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel of its own selection and the Company will pay the reasonable fees and expenses
of such counsel. The Company need not pay for any settlement made without its consent, which consent will not be unreasonably withheld. 

(c) The obligations of the Company under Section 7.02 and 7.07 will survive the resignation or removal of the Trustee and the satisfaction
and discharge of this Indenture. 

  
 23 













 (d) To secure the Company’s payment obligations in this Section 7.07, the Trustee
will have a Lien prior to the Notes on all money or properly held or collected by the Trustee. Such Lien will survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. 

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(e) or (f) hereof occurs,
the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 

(f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable. 

(g) “Trustee” for the purposes of this Section 7.07 shall include any predecessor Trustee and the Trustee in each of its
capacities hereunder and each agent, custodian and other person employed to act hereunder; provided, however, that the negligence or willful misconduct of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 

Section 7.08 Replacement of Trustee. 

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section 7.08. 
 (b) The Trustee may resign in writing at any time and be discharged from
the trust hereby created with respect to one or more Series of Notes by so notifying the Company with 30 days prior notice. The Holders of a majority in aggregate principal amount of the then outstanding Notes of such Series may remove the Trustee
by so notifying the Trustee and the Company with 30 days prior notice in writing. The Company may remove the Trustee with respect to one or more Series of Notes with 30 days prior written notice if: 

(1) the Trustee fails to comply with Section 7.10 hereof; 

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any
Bankruptcy Law; 
 (3) a custodian or public officer takes charge of the Trustee or its property; or 

(4) the Trustee becomes incapable of acting. 

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes of such Series may appoint a successor Trustee to replace the successor Trustee
appointed by the Company. 
 (d) If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed,
the retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes of such Series may petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a
successor Trustee. 
 (e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply
with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders.
The retiring Trustee will promptly transfer all properly held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof.
Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee.

 Section 7.09 Successor Trustee by Merger, etc.

surplus of at least $100.0 million as set forth in its most recent published annual report of condition. 
 This Indenture will always have

Any application by the Trustee for written instructions from the Company 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 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 an omission), the Trustee has received written instructions in response to such application specifying the
action to be taken or omitted. 
 ARTICLE 8 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. 

The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officer’s Certificate,
elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 

Section 8.02 Legal Defeasance and Discharge. 

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company will, subject
to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes of such Series on the date the conditions set forth below are satisfied
(hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes of such Series, which will
thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all their other obligations under
such Notes and this Indenture (and the Trustee, on written demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or
discharged hereunder: 

  
 25 













 (a) the rights of Holders of outstanding Notes to receive payments in respect of the
principal of, or interest or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 

(b) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof; 

(c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith; and

 (d) this Article 8. 

Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise
of its option under Section 8.03 hereof. 
 Section 8.03 Covenant Defeasance. 

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the
guarantors, if any, will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under the covenants contained in Section 4.03 and any other covenants specified in the applicable
Board Resolutions, supplemental indenture or Officer’s Certificate as being subject to covenant defeasance pursuant to this Section 8.03, in each case, with respect to the outstanding Notes of the applicable Series on and after the date
the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act
of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for
accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes of such Series, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth
in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise
under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, the failure to comply with any such covenants shall not constitute an
Event of Default pursuant to Section 6.01(d). 
 Section 8.04 Conditions to Legal or Covenant Defeasance. 

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 

(a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be sufficient, in the written opinion of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants delivered to the Trustee, to pay the
principal of, premium, if any, and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated
date for payment or to a particular redemption date; 
 (b) in the case of an election under Section 8.02 hereof, the Company must
deliver to the Trustee an Opinion of Counsel confirming that: 

  
 26 













 (1) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling; or 
 (2) since the date of this Indenture, there has been a change in the applicable
federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the beneficial
owners of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred; 
 (c) in the case of an election under Section 8.03 hereof, the
Company must deliver to the Trustee an Opinion of Counsel confirming that the beneficial owners of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company is a party or by which the Company is bound;

 (e) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 

(f) the Company must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 

(g) the Company must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent
relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 8.05 Deposited Money and Government
Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.06 hereof, all money and non-callable
Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of
the outstanding Notes of any Series will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as
Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent
required by law. 
 The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the
cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the
outstanding Notes of the applicable Series. 
 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay
to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance. 

  
 27 













 Section 8.06 Repayment to Company. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium,
if any, or interest on, any Series of Notes and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall, subject to applicable abandoned property law, be paid to the Company on its
request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to 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 all liability of the Company as trustee thereof, will 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 The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 Section 8.07
Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities
in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and any
applicable guarantors’ obligations under this Indenture and the applicable Notes and the guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on, any
Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 

ARTICLE 9 
 AMENDMENT,
SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 

Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Notes of one or
more Series without the consent of any Holder of Note: 
 (a) to cure any ambiguity or to correct or supplement any provision contained
herein or in any supplemental indenture that may be defective or inconsistent with any other provision contained herein or in any supplemental indenture, or to conform the provisions of this Indenture to the description of the Notes contained in the
prospectus or other offering document pursuant to which the Notes of one or more Series were sold, as evidenced by an Officer’s Certificate stating that such text constitutes an unintended conflict with the description of the corresponding
provision in the offering document; 
 (b) to provide for uncertificated Notes in addition to or in place of certificated Notes; 

(c) to provide for the assumption of the Company’s obligations to the Holders of the Notes by a successor to the Company pursuant to
Article 5 hereof; 
 (d) to make any change that would provide any additional rights or benefits to the Holders of all or any Series of Notes
or that does not adversely affect the rights hereunder of any Holder in any material respect, as evidenced by an Officer’s Certificate; 

(e) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 

  
 28 













 (f) to provide for the issuance of and establish the form and terms and conditions of Notes
of any Series as permitted by this Indenture; 
 (g) to add guarantees with respect to the Notes of any Series or to provide security for the
Notes of any Series; or 
 (h) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the
Notes of one or more Series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee. 

Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and
upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make
any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or
otherwise. 
 Section 9.02 With Consent of Holders of Notes. 

The Company and the Trustee may enter into a supplemental indenture with the written consent of the Holders of at least a majority in aggregate
principal amount of the outstanding Notes of each Series affected by such supplemental indenture (including consents obtained in connection with a tender offer or exchange offer for the Notes of such Series), for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of Notes of each such Series. Except as otherwise provided herein, the
Holders of at least a majority in aggregate principal amount of the outstanding Notes of each Series, by notice to the Trustee (including consents obtained in connection with a tender offer or exchange offer for the Notes of such Series) may waive
compliance by the Company with any provision of this Indenture or the Notes with respect to such Series. 
 It shall not be necessary for
the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed supplemental indenture or waiver, but it shall be sufficient if such consent approves the substance thereof. Upon the request of the
Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of
Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental
indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 

After a supplemental indenture or waiver under this section becomes effective, the Company shall mail to the Holders of Notes affected thereby
a notice briefly describing the supplemental indenture or waiver. Any failure by the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.
However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not, with respect to any Notes held by a non-consenting Holder: 

(a) reduce the principal amount, any premium or change the Stated Maturity of any Note or alter or waive any of the provisions with respect to
the redemption or repurchase of the Notes; 
 (b) reduce the rate (or alter the method of computation) of or extend the time for payment of
interest, including defaulted interest, on any Note; 
 (c) waive a Default or Event of Default in the payment of principal of or premium, if
any, or interest on the Notes, except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes of such Series with respect to a nonpayment default and a waiver of the
payment default that resulted from such acceleration; 

  
 29 













 (d) make the principal of or premium, if any or interest on any Note payable in currency
other than that stated in the Notes; 
 (e) change any place of payment where the Notes of any series or interest thereon is payable; 

(f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of the Notes to receive
payments of principal of or premium, interest, if any, on the Notes and to institute suit for the enforcement of any such payments; 
 (g)
make any change in the foregoing amendment and waiver provisions; or 
 (h) reduce the percentage in principal amount of any Notes, the
consent of the Holders of which is required for any of the foregoing modifications or otherwise necessary to modify or amend this Indenture or to waive any past Defaults. 

Section 9.03 Compliance with Trust Indenture Act. 

Every amendment to this Indenture or the Notes of one or more Series will be set forth in a supplemental indenture hereto that complies with
the TIA as then in effect. 
 Section 9.04 Revocation and Effect of Consents. 

Until an amendment or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke
the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment or waiver becomes effective. An amendment or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

Section 9.05 Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about an amendment or waiver on any Note of any Series thereafter authenticated. The Company in
exchange for Notes of that Series may issue and the Trustee shall authenticate upon request new Notes of that Series that reflect the amendment or waiver. 

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment or waiver. 

Section 9.06 Trustee to Sign Amendments, etc. 

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture, and an Opinion of Counsel stating that it will be the legal, valid and binding upon the Company in accordance with its terms, subject to customary exceptions. The Trustee
shall sign all supplemental indentures, except that the Trustee need not sign any supplemental indenture that adversely affects its rights. 

ARTICLE 10 
 SATISFACTION
AND DISCHARGE 
 Section 10.01 Satisfaction and Discharge. 

This Indenture will be discharged and will cease to be of further effect as to a Series of Notes issued hereunder, when: 

  
 30 













 (a) either: 

(1) all such Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and
Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 

(2) all such Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the
sending of a notice of redemption or otherwise or will become due and payable within one year and the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of such
Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not
delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; 
 (b)
no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or
violation of, or constitute a default under, any other material instrument to which the Company or any guarantor, as applicable, is a party or by which the Company, or any guarantor, as applicable, is bound; 

(c) the Company or any guarantor of such Notes has paid or caused to be paid all sums payable by it under this Indenture; and 

(d) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of
the Notes at maturity or on the redemption date, as the case may be. 
 In addition, the Company must deliver an Officer’s Certificate and an Opinion
of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the
satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (2) of clause (a) of this Section 10.01, the provisions of Sections 10.02 and 8.06 hereof will survive. In addition,
nothing in this Section 10.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. After the conditions to discharge contained in this Article
Ten have been satisfied, and the Company has paid or caused to be paid all other sums payable hereunder by the Company, and delivered to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that all conditions precedent to
satisfaction and discharge have been satisfied, the Trustee upon Company request shall acknowledge in writing the discharge of the obligations of the Company (except for those surviving obligations specified in this Section 10.01 and the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith). 
 Section 10.02
Application of Trust Money. 
 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee
pursuant to Section 10.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes with respect to which such deposit was made and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but
such money need not be segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to
apply any money or Government Securities in accordance with Section 10.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company’s and any applicable guarantor’s obligations under this Indenture and the applicable Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.01 hereof; provided
that if the Company has made any 

  
 31 













 
payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

of all classes of the Company’s Common Equity immediately prior to such transaction own, directly or indirectly, more than 50% of all classes of Common Equity of the continuing or surviving corporation or transferee or the parent thereof

case as applicable, by this Second Supplemental Indenture and to the extent expressly permitted hereunder. 
 Section 2.02. Form of
Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the respective forms set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby expressly
incorporated in and made a part of the Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of this Second Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby.

 Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with
the provisions of the Indenture as may be required by the Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated
quotation system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject. 

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the Officer
executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any
particular Notes are subject. 

  
 11 













 Each Global Note shall represent such principal amount of the outstanding Notes as shall be
specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time
be increased or reduced to reflect repurchases, cancellations, conversions, transfers or exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented
thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with the Indenture. Payment of principal (including the Fundamental Change
Repurchase Price, if applicable) of, and accrued and unpaid interest on, a Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders eligible to receive payment is
provided for herein. 
 Section 2.03. Date and Denomination of Notes; Accrual and Payments of Interest and Defaulted Amounts.
(a) The Notes shall be issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. Each Note shall be dated the date of its authentication and shall bear interest from the date
specified on the face of such Note. Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial
months, on the basis of the number of days actually elapsed in a 30-day month. Each Note will accrue interest at a rate per annum equal to 6.00% (the “Stated Interest”), plus any Additional
Interest that may accrue pursuant to Section 5.04. Stated Interest on each Note will accrue from, and including, the most recent date to which Stated Interest has been paid or duly provided for (or, if no Stated Interest has theretofore been
paid or duly provided for, the date set forth in the certificate representing such Note as the date from, and including, which Stated Interest will begin to accrue in such circumstance) to, but excluding, the date of payment of such Stated Interest.

 (b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Regular
Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. The principal amount of any Note (x) in the case of any Physical Note, shall be payable at the office or
agency of the Company maintained by the Company for such purposes in the contiguous United States, which shall initially be the Corporate Trust Office of the Trustee and (y) in the case of any Global Note, shall be payable by wire transfer of
immediately available funds to the account of the Depositary or its nominee. The Company shall pay interest (i) on any Physical Notes (A) to Holders holding Physical Notes having an aggregate principal amount of $5,000,000 or less, by
check mailed to the Holders of these Notes at their address as it appears in the Note Register and (B) to Holders holding Physical Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to each Holder or,
upon application by such a Holder to the Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect
until the Holder notifies, in writing, the Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. 

  
 12 













 (c) Section 2.13 of the Base Indenture shall not apply to the Notes. Any Defaulted Amounts
shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes plus one percent, subject to the enforceability thereof under applicable law, from, and
including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: 

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective
Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the
Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time
the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the
proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted
Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the
Trustee of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be mailed, first class postage prepaid,
to each Holder at its address as it appears in the Note Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so mailed, such
Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause
(ii) of this Section 2.03(c). 
 (ii) The Company may make payment of any Defaulted Amounts in any other lawful
manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation
system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

Section 2.04. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The last sentence of
the first paragraph of Section 2.07 of the Base Indenture and the second paragraph of Section 2.07 of the Base Indenture shall not apply to the Notes. 

(b) No service charge shall be imposed by the Company, the Trustee, the Registrar, any co-Registrar or
the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the
name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer. 

  
 13 













 Notwithstanding anything to the contrary in the Indenture, none of the Company, the Trustee,
the Registrar or any co-Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion
thereof surrendered for conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 12. 

(c) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the third
paragraph of Section 2.04(d), all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of
beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture and the procedures of the Depositary
therefor. 
 (d) Notwithstanding any other provisions of the Indenture (other than the provisions set forth in this Section 2.04(d)), a
Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such
nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding paragraph. 

The 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. 

Section 2.14(b) of the Base Indenture shall not apply to the Notes. If (i) the Depositary notifies the Company at any time that the
Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor
depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the
Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such
beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the
related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall
be canceled. 

  
 14 













 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this
Section 2.04(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately
preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon
receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical
Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance
with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase. 
 None of the Company, the Trustee or any agent of the Company or the
Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. 
 (e) Any Note issued upon the conversion or exchange of a Note that is repurchased or owned by any
Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold
pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note no longer being a “restricted security” (as defined under Rule 144 as promulgated under the Securities Act). The
Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.12 of the Base Indenture (as amended by Section 2.06 of this Second Supplemental Indenture).

 Section 2.05. Mutilated, Destroyed, Lost or Stolen Notes. The second sentence of Section 2.08 of the Base Indenture
shall not apply to the Notes. No service charge shall be imposed by the Company, the Trustee, the Registrar, any co-Registrar or the Paying Agent upon the issuance of any substitute Note as provided in
Section 2.08 of the Base Indenture, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new
substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about
to be converted in accordance with Article 11 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 

  
 15 













 
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. 

To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with
respect to the replacement, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with
respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender. 

Section 2.06. Cancellation of Notes Paid, Converted, Etc. Section 2.12 of the Base Indenture is hereby amended with respect
to the Notes by (i) replacing the first sentence thereof with the sentence: “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 Affiliates), to be surrendered to the Trustee for cancellation” and (ii) inserting at the end of the fourth sentence thereof the phrase “,
except as expressly permitted by any of the provisions of the Indenture”. 
 Section 2.07. Additional Notes; Repurchases.
The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen the Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue
price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal
income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel,
such Officer’s Certificate and Opinion of Counsel to cover such matters, in addition to those required by Sections 2.03 and 11.05 of the Base Indenture, as the Trustee shall reasonably request. In addition, the Company may, to the extent
permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or
exchange offer or through counterparties pursuant to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other
derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.06 and such Notes shall no longer be considered outstanding under the Indenture upon their repurchase.

Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.08 of the Base Indenture (as amended by Section 2.05 of this
Second Supplemental Indenture)) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity

all other sums due and payable under the Indenture by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent in the Indenture provided

Base Indenture shall not apply to the Notes. 
 (b) 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 4.03: 

(i) that it will hold all sums held by it as such agent for the payment of the principal (including 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;

Trustee all sums so held in trust.

Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid
interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent
by 11:00 a.m., New York City time, on such date. 
 (c) If the Company shall act as its own Paying Agent, it will, on or before each due date
of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such
principal (including the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make
any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable. 

(d) Anything in this Section 4.03 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a
satisfaction and discharge of the 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 4.03, 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. 

  
 18 













 (e) All references in the Base Indenture to such Section 8.06 shall, with respect to
the Notes, be deemed to be references to this Section 4.03(e). Any money and Common Shares deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Fundamental Change
Repurchase Price, if applicable) of, accrued and unpaid interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price, if applicable),
interest or consideration due upon conversion has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money and Common Shares, 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 Common Shares remain unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money and Common Shares then remaining will be repaid or delivered to the Company. 

Section 4.04. Reports. (a) The Company shall file with the Trustee, within 15 days after the same are required to be filed
with the SEC, copies of any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule
12b-25 under the Exchange Act). Any such document or report that the Company files with the SEC via the SEC’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this
Section 4.04 (a) at the time such documents are filed via the EDGAR system. 
 (b) Delivery of the reports and documents described in
subsection (a) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein,
including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate). 

Section 4.05. Statements as to Defaults. The Company shall deliver to the Trustee within 30 days after the occurrence of any Event
of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or proposing to take in respect thereof.

$15,000,000 (or its foreign currency equivalent) in the aggregate of the Company and/or any such Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due
and payable or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, and such acceleration is not
cured, waived, rescinded, stayed or annulled or such indebtedness is not discharged, as applicable, within a period of 30 days after written notice of such indebtedness becoming due and payable or such failure, as the case may be, has been received
from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding; 

  
 20 













 (h) a final judgment or judgments for the payment of $10,000,000 (or its foreign currency

custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive days. 

Section 5.03. Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body), then, and in each and every such case (other than an Event of Default specified in Section 5.02(i) or Section 5.02(j) with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of
the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company (and to the Trustee if given by Holders), may
declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in
the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 5.02(i) or Section 5.02(j) with respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 100% of the
principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable. 

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

  
 21 













 
Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable
under applicable law, and on such principal at the rate borne by the Notes plus one percent at such time) and amounts due to the Trustee pursuant to Section 7.07 of the Base Indenture, and if (1) rescission would not conflict with
any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have
become due solely by such acceleration, shall have been cured or waived pursuant to Section 5.09, 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 the Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall
impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal
(including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the
consideration due upon conversion of the Notes. 
 Section 5.04. Additional Interest. Notwithstanding anything in the Indenture
or in the Notes to the contrary, if the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.03 of the Base Indenture or Section 4.04(a) of
this Second Supplemental Indenture 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 (x) 0.25% per annum of the principal amount of the Notes
outstanding for each day during the 90-day period on which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs and ending on, but excluding,
the earlier of (A) the date on which such Event of Default is no longer continuing and (B) the 91st day following the date on which such an Event of Default first occurs, and (y) 0.50% per annum of the principal amount of the Notes
outstanding for each day during the 90-day period on which such Event of Default is continuing beginning on, and including, the 91st day following the date on which such an Event of Default first occurs and
ending on, but excluding, the date on which such Event of Default is no longer continuing. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On
the 181st day after such Event of Default (if such Event of Default is not cured or waived prior to such 181st day), the Notes shall be immediately subject to acceleration as provided in Section 5.03. The provisions of this paragraph will not
affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in Section 4.03 of the Base Indenture and Section 4.04(a) of
this Second Supplemental Indenture. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 5.04 or the Company elected to make such payment but does not pay the
Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 5.03. 

  
 22 













 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 5.03. 

Section 5.05. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of
Section 5.02 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with
interest on any overdue principal and interest, if any, at the rate borne by the Notes plus one percent at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under
Section 7.07 of the Base Indenture. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so
due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Notes, wherever situated. 
 In any proceedings brought by the Trustee (and in any
proceedings involving the interpretation of any provision of the 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. 
 Section 5.06. Application of Monies Collected by Trustee. Any monies collected by the
Trustee pursuant to this Article 5 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the payment of all amounts due the Trustee
under Section 7.07 of the Base Indenture; 
 Second, in case the principal of the outstanding Notes shall not have become due
and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that
such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, plus one percent, such payments to be made ratably to the Persons entitled thereto; 

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment
of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal
and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time plus one percent, 

  
 23 













 
and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental
Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note
over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and 

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

Section 5.07. Proceedings by Holders. Section 6.06 of the Base Indenture shall not apply to the Notes. Except to enforce the
right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have
any right by virtue of or by availing of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a receiver, trustee, liquidator,
custodian or other similar official, or for any other remedy hereunder, unless: 
 (a) such Holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof, as herein provided; 
 (b) Holders of at least 25% in aggregate
principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 

(c) such Holders shall have offered to the Trustee such security or indemnity reasonably satisfactory to it against any loss, liability or
expense to be incurred therein or thereby; 
 (d) the Trustee for 60 days after its receipt of such notice, request and offer of such
security or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 
 (e) no direction that, in the
opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such
60-day period pursuant to Section 5.09, 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 the 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 the Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein) (it being understood that the Trustee does
not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders). For the protection and enforcement of this Section 5.07, each and every Holder and the Trustee shall be entitled to
such relief as can be given either at law or in equity. 

  
 24 













 Notwithstanding any other provision of the Indenture and any provision of any Note, the
right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration
due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such
respective dates against the Company shall not be impaired or affected without the consent of such Holder. 
 Section 5.08. Remedies
Cumulative and Continuing. Except as provided in the last paragraph of Section 2.05, all powers and remedies given by this Article 5 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 the
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 5.07, every power and remedy given by this Article 5 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 5.09. 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 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its
consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of
Section 5.02, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 9 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 5.09, said Default or Event of Default
shall for all purposes of the Notes and the 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 5.10. Notice of Defaults. Section 7.05 of the Base Indenture is hereby amended with respect to the Notes by inserting
immediately prior to the words “any Note” in the third line thereof the phrase “, or a Default or Event of Default in the payment or delivery of the consideration due upon conversion in respect of,”. 

  
 25 













 Section 5.11. Undertaking to Pay Costs. All parties to the 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 the 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 5.11 (to the extent permitted by law)
shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding, 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, if applicable) on or after the due date expressed or provided
for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions of Article 11.

 ARTICLE 7 

CONCERNING THE HOLDERS 

Section 7.01. Applicability of Section 2.14(f) of the Base Indenture. Section 2.14(f) of the Base
Indenture shall not apply to the Notes. 
 Section 7.02. Action by Holders. Whenever in the Indenture it is provided that the
Holders of a specified percentage of the aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the
time of taking any such action, the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in
writing, or (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 8, or (c) by a combination of such instrument or instruments and any such
record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the
record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action.

 Section 7.03. Proof of Execution by Holders. Subject to the provisions of
Section 7.01 of the Base Indenture, Section 7.02 of the Base Indenture and Section 8.06 of this Second Supplemental Indenture, 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 Registrar. The
record of any Holders’ meeting shall be proved in the manner provided in Section 8.07. 
 Section 7.04. Who Are Deemed
Absolute Owners. The second sentence of Section 2.14(e) of the Base Indenture shall not apply to the Notes. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Registrar may deem the Person in
whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any
Person other than the Company or any 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 Registrar shall be affected by any notice to the contrary. All such payments or deliveries so made to any Holder for the time being, or upon its
order, shall be valid, and, to the extent of the sums or Common Shares so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in
the 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 the Indenture. 

Section 7.05. Company-Owned Notes. Notes that are owned as described in Section 2.10 of the Base Indenture that have been
pledged in good faith may be regarded as outstanding for the purposes of such Section 2.10 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is
not the Company, a Subsidiary thereof or an Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon
request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons;
and, subject to Section 7.01 of the Base Indenture, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding
for the purpose of any such determination. 
 Section 7.06. Revocation of Consents; Future Holders Bound. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 7.02, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in the Indenture in connection with such action,
any Holder of a Note that is shown by the evidence to 

  
 27 













 
be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at the Corporate Trust Office of the Trustee and upon proof of holding
as provided in Section 7.03, 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.

setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting and the establishment of any record date pursuant to Section 7.02, shall be mailed to Holders of such Notes at their
addresses as they shall appear on the Note Register. Such notice shall also be mailed to the Company. Such notices shall be mailed not less than 20 nor more than 90 days prior to the date fixed for the meeting. 

Any meeting of Holders shall be valid without notice if the Holders of all Notes then outstanding are present in person or by proxy or if
notice is waived before or after the meeting by the Holders of all Notes then outstanding, and if the Company and the Trustee are either present by duly authorized representatives or have, before or after the meeting, waived notice.

Company, pursuant to a Board Resolution, or the Holders of at least 10% of the aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within 20 days after receipt of such request, then the Company or such Holders may determine the time and the place for such
meeting and may call such meeting to take any action authorized in Section 8.02, by mailing notice thereof as provided in Section 8.03. 

Section 8.05. Qualifications for Voting. To be entitled to vote at any meeting of Holders a Person shall (a) be a Holder of

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

Section 8.06. Regulations. Notwithstanding any other provisions of the Indenture, the Trustee may make such reasonable regulations
as it may deem advisable for any meeting of Holders, in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 8.04, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the
meeting shall be elected by vote of the Holders of a majority in aggregate principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 

Subject to the provisions of Section 2.10 of the Base Indenture and Section 7.05, at any meeting of Holders each Holder or
proxyholder shall be entitled to one vote for each $1,000 principal amount of Notes held or represented by him or her; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not
outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating it as the proxy to
vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 8.03 or Section 8.04 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of Notes
represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice. 

  
 29 













 Section 8.07. Voting. The vote upon any resolution submitted to any meeting of
Holders shall be by written ballot on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the outstanding aggregate principal amount of the Notes held or represented by them. The permanent chairman of the
meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at
the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken
thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 8.03. The record shall show the aggregate principal
amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the
other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 
 Any record so
signed and verified shall be conclusive evidence of the matters therein stated. 
 Section 8.08. No Delay of Rights by Meeting.
Nothing contained in this Article 8 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise

shall not apply to the Notes. Instead, the supplemental indenture provisions set forth in Section 9.02 and Section 9.03, respectively, shall, with respect to the Notes, supersede in their entirety Section 9.01 and Section 9.02 of
the Base Indenture, and all references in the Base Indenture to such Sections and amendment and waiver provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to Section 9.02 and Section 9.03,
as applicable, and the supplemental indenture provisions set forth therein. 
 Section 9.02. Supplemental Indentures Without Consent
of Holders. The Company, at the Company’s expense, may, along with the Trustee, from time to time and at any time enter into an indenture or indentures supplemental hereto for one or more of the following purposes:

 (g) to make any change that does not adversely affect the rights of
any Holder, as confirmed by an Officer’s Certificate delivered to the Trustee; 
 (h) in connection with any Merger Event, to provide
that the Notes are convertible into Reference Property, subject to the provisions of Section 11.02, and make such related changes to the terms of the Notes to the extent expressly required by Section 11.07; or 

(i) to irrevocably elect or eliminate any Settlement Method or Specified Dollar Amount; provided, however, that no such election
or elimination will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note pursuant to Section 11.02. 

Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental
indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own
rights, duties or immunities under the Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this
Section 9.02 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 9.03. 

Section 9.03. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 7) of the
Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 7 and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange
offer for, Notes), the Company, at the Company’s expense, may, along with the Trustee, from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that, without the consent of each Holder of an outstanding Note

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

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

obligation to make such payments, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise; 
 (h)
make any Note payable in a currency, or at a place of payment, other than that stated in the Note; 
 (i) change the ranking of the Notes; or

 (j) make any change in this Article 9 that requires each Holder’s consent or in the waiver provisions in Section 5.03 or
Section 5.09. 
 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as
aforesaid and subject to Section 9.06 of the Base Indenture, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities
under the Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

Holders do not need under this Section 9.03 to approve the particular form of any proposed supplemental indenture. It shall be sufficient
if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all
the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 
 Section 9.04.
Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 9, the Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective
rights, limitation of rights, obligations, duties and immunities under the Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and
amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of the Indenture for any and all purposes. 

ARTICLE 10 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 10.01. Applicability of Article 5 of the Base Indenture. Article 5 of the Base Indenture shall not apply to the Notes.
Instead, the consolidation, merger, sale, conveyance and lease provisions set forth in this Article 10 shall, with respect to the Notes, supersede in their entirety such Article 5 of the Base Indenture, and all references in the Base Indenture to
such Article and the Company successor provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 10 and the consolidation, merger, sale, conveyance and lease provisions set forth in this
Article 10, respectively. 

  
 32 













 Section 10.02. Company May Consolidate, Etc. on Certain Terms. Subject to the
provisions of Section 10.03, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the
Company under the Notes and the Indenture; and 
 (b) immediately after giving effect to such transaction, no Default or Event of Default
shall have occurred and be continuing under the Indenture. 
 For purposes of this Section 10.02, the sale, conveyance, transfer or
lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all
of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

Section 10.03. Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or
lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on
all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by the
Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had
been named herein as the party of the first part. 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 the Indenture prescribed, the Trustee shall authenticate and
shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by an Officer of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall
cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under the Indenture as the Notes theretofore or thereafter issued in accordance with the terms of
the 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 10 the
Person named as the “Company” in the first paragraph of this Second Supplemental Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 10) 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 the Indenture and the Notes. 

  
 33 













 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 10.04. Opinion of Counsel to Be Given to Trustee. No such consolidation, merger, sale, conveyance, transfer or lease shall
be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental
indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 10. 

ARTICLE 11 

CONVERSION OF NOTES 

Section 11.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 11, each Holder
of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions
described in Section 11.01(b), at any time prior to the close of business on the Business Day immediately preceding September 1, 2025 and (ii) regardless of the conditions described in Section 11.01(b), on or after
September 1, 2025 and prior to the close of business on the Business Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 127.8119 Common Shares (subject to adjustment as provided in this Article 11, the
“Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 11.02, the “Conversion Obligation”). 

(b) (i) Prior to the close of business on the Business Day immediately preceding September 1, 2025, a Holder may surrender all or any
portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of
Notes, as determined following a request by a Holder 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 Shares on each
such Trading Day and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Second Supplemental
Indenture. If the Company is not acting as the Bid Solicitation Agent, then 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. If the Company is not acting as the Bid Solicitation Agent, then 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. The Company shall have no obligation to make such request (if it is not acting as the Bid Solicitation Agent), and the Company shall have no obligation to determine the
Trading Price per $1,000 principal amount of Notes (if it is acting as the Bid 

  
 34 













 
Solicitation Agent), unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the
product of the Last Reported Sale Price of the Common Shares on such Trading Day and the Conversion Rate on such Trading Day, at which time the Company (if it is not acting as the Bid Solicitation Agent) shall instruct the Bid Solicitation Agent to
determine (or, if the Company is acting as the Bid Solicitation Agent, the Company shall determine) the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price
per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Shares and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent and does not instruct
the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, (y) the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation
Agent fails to make such determination, or (z) the Company is acting as Bid Solicitation Agent and fails to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, then, in each
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 Shares 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 Shares and the Conversion Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the
Conversion Agent (if other than the Trustee). 
 (ii) If, prior to the close of business on the Business Day immediately
preceding September 1, 2025, the Company elects to: 
 (A) issue to all or substantially all holders of the Common
Shares 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 Common Shares at a price per share that is less than the average of the
Last Reported Sale Prices of the Common Shares for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 

(B) distribute to all or substantially all holders of the Common Shares the Company’s assets, 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 Shares 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 60 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, a Holder may surrender all or any portion of
its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the
Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time. 

  
 35 













 (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 September 1, 2025, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to
Section 12.02, or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets, in each case, that occurs prior to the close of business on the Business Day
immediately preceding September 1, 2025 and pursuant to which the Common Shares would be converted into cash, securities or other assets, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after
the date that is 60 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) (x) as promptly
as practicable following the date the Company publicly announces such transaction but in no event less than 60 Scheduled Trading Days prior to the anticipated effective date of such transaction or (y) if the Company does not have knowledge of
such transaction at least 60 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day 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 September 1, 2025, a Holder may surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on March 31, 2021 (and only during such
calendar quarter), if the Last Reported Sale Price of the Common Shares for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar
quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. The Conversion Agent, on behalf of the Company, shall determine at the beginning of each calendar quarter commencing after March 31, 2021 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). 

Section 11.02. Conversion Procedure; Settlement upon Conversion. 

(a) Subject to this Section 11.02, Section 11.03(b) and Section 11.07(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”), Common Shares, together with cash, if applicable, in lieu of delivering any


  
 36 













 
fractional Common Shares in accordance with subsection (j) of this Section 11.02 (“Physical Settlement”) or a combination of cash and Common Shares, together with cash,
if applicable, in lieu of delivering any fractional Common Shares in accordance with subsection (j) of this Section 11.02 (“Combination Settlement”), at its election, as set forth in this Section 11.02. 

(i) All conversions for which the relevant Conversion Date occurs on or after September 1, 2025 shall be settled using the
same Settlement Method. 
 (ii) Except for any conversions for which the relevant Conversion Date occurs on or after
September 1, 2025, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different
Conversion Dates. 
 (iii) If, in respect of any Conversion Date (or the period described in the third immediately succeeding
set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company,
through the Trustee, shall deliver such Settlement Notice to converting Holders no later than the close of business on the second Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the
relevant Conversion Date occurs on or after September 1, 2025, no later than September 1, 2025). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no
longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of
Notes shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000
principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement
Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. 
 By notice to
Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee), the Company may, prior to September 1, 2025, at its option, irrevocably elect to satisfy its Conversion Obligation with respect to the Notes through a
Combination Settlement with a Specified Dollar Amount per $1,000 principal amount of Notes of $1,000 for all Conversion Dates occurring subsequent to delivery of such notice. Not later than three Business Days after providing notice to Holders, the
Trustee and the Conversion Agent (if other than the Trustee) of an irrevocable election with respect to the Settlement Method as described in the immediately preceding sentence, the Company shall issue a Current Report on Form 8-K or press release or otherwise provide public disclosure in a manner compliant with Regulation FD announcing that the Company has made such irrevocable election. For the avoidance of doubt, such an irrevocable
election, if made, will be effective without the need to amend this Second Supplemental Indenture or the Notes, including pursuant to Section 9.02(i). However, the Company may, nonetheless, choose to execute such an amendment at its option.


  
 37 













 (iv) The cash, Common Shares or combination of cash and Common Shares in
respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 
 (A) if the
Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Notes being converted a number of Common
Shares equal to the Conversion Rate in effect on the Conversion Date; 
 (B) if the Company elects to satisfy its Conversion
Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for
each of the 50 consecutive Trading Days during the related Observation Period; and 
 (C) if the Company elects (or is deemed
to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement
Amount equal to the sum of the Daily Settlement Amounts for each of the 50 consecutive Trading Days during the related Observation Period. 

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

(b) Subject to Section 11.02(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 11.02(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 Common Shares to be delivered upon settlement of the Conversion Obligation to be registered, (2) 

  
 38 













 
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 11.02(h). The Trustee (and if
different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 11 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such
Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 12.03. 

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

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 11.03(b) and Section 11.07(a), the Company shall pay or deliver, as the case may be, the
consideration due in respect of the Conversion Obligation on the second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the second Business Day immediately following the last Trading
Day of the Observation Period, in the case of any other Settlement Method. If any Common Shares are due to converting Holders, the Company shall issue or cause to be issued, and deliver (if applicable) to the Conversion Agent or to such Holder, or
such Holder’s nominee or nominees, the full number of Common Shares to which such Holder shall be entitled, in certificate form or in book-entry format, in satisfaction of the Company’s Conversion Obligation. 

(d) In case any Note shall be surrendered for partial conversion, the Company (1) in the case of a Global Note, shall cause the principal
balance of a Global Note to be adjusted in accordance with the procedures of the Depositary in effect at that time or (2) in the case of a Physical Note, shall execute and the Trustee shall authenticate and deliver to or upon the written order
of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but,
if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the
name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue
of any Common Shares upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver the
certificates representing the Common Shares 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. 

  
 39 













 (f) Except as provided in Section 11.04, no adjustment shall be made for dividends on
any Common Shares issued upon the conversion of any Note as provided in this Article 11. 
 (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, and the Company shall not adjust the Conversion Rate to adjust for any accrued and unpaid interest on the Notes. The Company’s settlement of the full Conversion
Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but
excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and Common Shares, 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 such Interest Payment Date, 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. Therefore, for the avoidance of doubt, all Holders
of record on the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date regardless of whether their Notes have been converted following such Regular Record Date. 

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

  
 40 













 (j) The Company shall not issue any fractional Common Shares upon conversion of the Notes
and shall instead pay cash in lieu of delivering any fractional Common Shares issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day
of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of Common Shares that shall be issued upon conversion thereof
shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional Common Shares remaining after such computation shall be paid in cash. 

Section 11.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental
Changes. (a) If a Make-Whole Fundamental Change occurs or becomes effective prior to the Maturity Date 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 Common Shares (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for
these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and
including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the
definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”). 

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to Section 11.01(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 11.02; provided, however, that if, at the effective time of a
Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective
Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Share 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 Share Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the second Business Day following the Conversion Date. The Company
shall notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change 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 “Share Price”) paid (or deemed to be paid) per Common Share in the Make-Whole
Fundamental Change. If the holders of the Common Shares receive in exchange for their Common Shares only cash in a Make-Whole Fundamental Change described in clause (b) of the 

  
 41 













 
definition of Fundamental Change, the Share Price shall be the cash amount paid per share. Otherwise, the Share Price shall be the average of the Last Reported Sale Prices of the Common Shares
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 Share Price, in its good faith
determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date (as such term
is used in Section 11.04) or expiration date of the event occurs during such five consecutive Trading Day period. 
 (d) The Share
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 Share Prices shall equal the Share 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 Share 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 11.04. 

(e) The following table sets forth the number of Additional Shares by which the Conversion Rate shall be increased per $1,000 principal amount
of Notes pursuant to this Section 11.03 for each Share Price and Effective Date set forth below:

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

(i) if the Share Price is between two Share 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 Share Prices and the earlier and later Effective Dates, as applicable, based
on a 365-day year; 
 (ii) if the Share Price is greater than $40.00 per share
(subject to adjustment in the same manner as the Share 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 Share Price is less than $6.52 per share (subject to adjustment in the same manner as the Share 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. 

  
 42 













 Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes
exceed 153.3742 Common Shares, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 11.04. 
 (f) Nothing
in this Section 11.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 11.04 in respect of a Make-Whole Fundamental Change. 

Section 11.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the
following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange
offer), at the same time and upon the same terms as holders of the Common Shares and solely as a result of holding the Notes, in any of the transactions described in this Section 11.04, without having to convert their Notes, as if they held a
number of Common Shares equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

(a) If the Company exclusively issues Common Shares as a dividend or distribution on Common Shares, or if the Company effects a share split or
share combination, the Conversion Rate shall be adjusted based on the following formula: 
 CR’= CR0 × OS’ 

                     OS0 
  

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

 Any adjustment made under this Section 11.04(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 11.04(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. 

  
 43 













 (b) If the Company issues to all or substantially all holders of the Common Shares 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 Common Shares at a price per share that is less than the average of the Last
Reported Sale Prices of the Common Shares for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the
following formula: 
 CR’= CR0 × OS0 + X 

                     OS0 + Y 
  

					
	 where,
	  	
			
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	 CR’
	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	 OS0
	  	=	  	the number of Common Shares outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	 X
	  	=	  	the total number of Common Shares issuable pursuant to such rights, options or warrants; and
			
	 Y
	  	=	  	the number of Common Shares 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 Shares over the 10 consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 11.04(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 Common Shares 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 Common Shares 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 11.04(b) and for the purpose of Section 11.01(b)(ii)(A), in
determining whether any rights, options or warrants entitle the holders to subscribe for or purchase Common Shares at less than such average of the Last Reported Sale Prices of the Common Shares for the 10 consecutive Trading Day period ending on,
and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such Common Shares, 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. 

  
 44 













 (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 Shares, excluding (i) dividends, distributions or issuances as to which
an adjustment was effected pursuant to Section 11.04(a) or Section 11.04(b), (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in Section 11.04(d) shall apply, and (iii) Spin-Offs as to
which the provisions set forth below in this Section 11.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the
“Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 
 CR’= CR0 ×

SP0  

                        
SP0 - FMV 
  

					
	 where,
	  	
			
	 CR0
	 	 =
	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	 CR’
	 	 =
	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	 SP0
	 	 =
	  	the average of the Last Reported Sale Prices of the Common Shares over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend
Date for such distribution; and
			
	 FMV
	 	 =
	  	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding Common Share on the Ex-Dividend Date for such
distribution.

 Any increase made under the portion of this Section 11.04(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing
increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Shares receive the Distributed Property, the amount and kind of Distributed Property
such Holder would have received if such Holder owned a number of Common Shares 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 11.04(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 Shares over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for
such distribution. 

  
 45 













 With respect to an adjustment pursuant to this Section 11.04(c) where there has been a
payment of a dividend or other distribution on the Common Shares of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be,
listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

CR’= CR0 ×
FMV0 + MP0 

                        
    MP0 
  

					
	where,	 		 	
			
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR’	 	=	 	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	 	=	 	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Shares applicable to one Common Share over the first 10 consecutive Trading Day period after, and
including, the Ex-Dividend Date of the Spin-Off (determined by reference to the definitions of Last Reported Sale Price, Trading Day and Market Disruption Event as set
forth in Section 1.02 as if references therein to Common Shares were to such Capital Stock or similar equity interest) (the “Valuation Period”); and
			
	MP0	 	=	 	the average of the Last Reported Sale Prices of the Common Shares over the Valuation Period.

 The increase to the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the Valuation Period;
provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references in the portion of this Section 11.04(c) related to
Spin-Offs to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the
Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such
conversion and within the Valuation Period, references in the portion of this Section 11.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. If the Ex-Dividend
Date of the Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references in the preceding paragraph to 10
Trading Days will be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period. 

  
 46 













 For purposes of this Section 11.04(c) (and subject in all respect to
Section 11.11), rights, options or warrants distributed by the Company to all holders of the Common Shares entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Shares (either initially or
under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such Common Shares; (ii) are not exercisable; and
(iii) are also issued in respect of future issuances of the Common Shares, shall be deemed not to have been distributed for purposes of this Section 11.04(c) (and no adjustment to the Conversion Rate under this Section 11.04(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 11.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date hereof, 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 11.04(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 Shares with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Shares 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 11.04(a), Section 11.04(b) and this Section 11.04(c), if any dividend or distribution to which this
Section 11.04(c) is applicable also includes one or both of: 
 (A) a dividend or distribution of Common Shares to which
Section 11.04(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options
or warrants to which Section 11.04(b) is applicable (the “Clause B Distribution”), 

  
 47 













 then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the
Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 11.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 11.04(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 11.04(a) and Section 11.04(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 Common Shares 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 11.04(a) or “outstanding immediately prior to the open
of business on such Ex-Dividend Date” within the meaning of Section 11.04(b). 
 (d) If any
cash dividend or distribution is made to all or substantially all holders of the Common Shares, excluding any consideration payable in connection with a tender offer or exchange offer made by the Company or any of its Subsidiaries, the Conversion
Rate shall be adjusted based on the following formula: 
  

			
	CR’= CR0 ×     SP0    
	                    SP0 - C

  

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

 Any increase pursuant to this Section 11.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or
pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of
the Common Shares, the amount of cash that such Holder would have received if such Holder owned a number of Common Shares equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or
distribution. 

  
 48 













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

 

			
	CR’= CR0 × AC + (SP’xOS’)
	                    OS0 ×SP’

  

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

 The increase to the Conversion Rate under this Section 11.04(e) shall occur at the close of business on the 10th Trading
Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the
relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section 11.04(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 and (y) in respect of any conversion of


  
 49 













 
Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days
immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section 11.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of
Trading Days as have elapsed between the expiration date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Trading Day next succeeding the date such tender or
exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references in the preceding paragraph to 10 Trading Days shall be deemed to be
replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer expires to, and including, the last Trading
Day of such Observation Period. 
 (f) Notwithstanding this Section 11.04 or any other provision of the 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 Common Shares as of the related Conversion Date as described under Section 11.02(i) based on an adjusted Conversion Rate for such
Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 11.04, 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 Common Shares 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 Common Shares
or any securities convertible into or exchangeable for Common Shares or the right to purchase Common Shares or such convertible or exchangeable securities. 

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 11.04, and to the extent
permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20
Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the
Company’s securities are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Shares or rights to purchase Common Shares in connection with a dividend or
distribution of Common Shares (or rights to acquire Common Shares) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address
appearing on the Note Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

  
 50 













 (i) Notwithstanding anything to the contrary in this Article 11, the Conversion Rate shall
not be adjusted: 
 (i) upon the issuance of any Common Shares 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 Common Shares under any plan; 

(ii) upon the issuance of any Common Shares 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 Common Shares 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) upon the repurchase of any Common Shares pursuant to an open-market share purchase program or other buy-back transaction, including structured or derivative transactions, that is not a tender offer or exchange offer of the kind described in Section 11.04 (e) above; 

(v) as a result of a tender offer solely to holders of fewer than 100 Common Shares; 

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

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

(j) All calculations and other determinations under this Article 11 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. The Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate. However,
the Company shall carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustments (1) upon conversion of any Note (x) if Cash Settlement or Combination Settlement is applicable to such
conversion, on each Trading Day in the Observation Period for such conversion and (y) if Physical Settlement is applicable to such conversion, on the relevant Conversion Date and (2) on each anniversary of the original issue date of the
Notes, in each case, without duplication and regardless of whether the aggregate adjustment is less than 1%. 
 (k) Whenever the Conversion
Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief
statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate
and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the
adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of the Indenture. Failure to
deliver such notice shall not affect the legality or validity of any such adjustment. 

  
 51 













 (l) For purposes of this Section 11.04, the number of Common Shares at any time
outstanding shall not include Common Shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on Common Shares held in the treasury of the Company, but shall include Common Shares issuable
in respect of scrip certificates issued in lieu of fractions of Common Shares. 
 Section 11.05. Adjustments of Prices. Whenever
any provision of the 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 Share Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring
an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices,
the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 
 Section 11.06. Shares to Be
Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient Common Shares to provide for conversion of the Notes from time to time as such Notes are
presented for conversion (assuming delivery of the maximum number of Additional Shares pursuant to Section 11.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that
Physical Settlement were applicable). 
 Section 11.07. Effect of Recapitalizations, Reclassifications and Changes of the Common
Shares. 
 (a) In the case of: 

(i) any recapitalization, reclassification or change of the Common Shares (other than changes resulting from a subdivision or
combination), 
 (ii) any consolidation, merger, combination or similar transaction involving the Company, 

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

in each case, as a result of which the Common Shares 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 

  
 52 













 
other property or assets (including cash or any combination thereof) that a holder of a number of Common Shares equal to the Conversion Rate immediately prior to such Merger Event would have
owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one Common Share 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 9.02(h)
providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the
form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 11.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 11.02 shall
continue to be payable in cash, (II) any Common Shares that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 11.02 shall instead be deliverable in the amount and type of Reference
Property that a holder of that number of Common Shares 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 Shares to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of shareholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of
consideration received by the holders of Common Shares that affirmatively make such an election or (y) if no holders of Common Shares affirmatively make such an election, the types and amounts of consideration actually received by the holders
of Common Shares, 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 Common Share. If the holders of the Common Shares
receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of Notes
shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 11.03), multiplied by the price paid per Common Share in such Merger Event
and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion
Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. 
 Such supplemental
indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 11. 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 the provisions providing for the purchase rights set forth in Article 12. 

  
 53 













 (b) When the Company executes a supplemental indenture pursuant to subsection (a) of
this Section 11.07, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or assets that will comprise a unit of Reference
Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly 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 the 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 11.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, Common Shares or a combination of cash and Common Shares, as applicable, as set forth in Section 11.01 and
Section 11.02 prior to the effective date of such Merger Event. 
 (d) The above provisions of this Section shall similarly apply to
successive Merger Events. 
 Section 11.08. Certain Covenants. (a) The Company covenants that all Common Shares issued upon
conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(a) The Company covenants that, if any Common Shares 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 Common Shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the SEC, secure such
registration or approval, as the case may be. 
 (b) The Company further covenants that if at any time the Common Shares shall be listed on
any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Shares shall be so listed on such exchange or automated quotation system, any Common Shares issuable upon conversion of the
Notes. 
 Section 11.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under
any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent
or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any Common Shares, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the


  
 54 













 
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 Common Shares 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 11.07 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 11.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any
such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the
Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 11.01(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 11.01(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 11.01(b). 

Section 11.10. 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 11.04 or
Section 11.11; 
 (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 the 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 or, in the case of Global Notes, such notice shall be delivered in accordance with
the applicable procedures of the Depositary, 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 Shares 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 Shares of record
shall be entitled to exchange their Common Shares 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. 

  
 55 













 Section 11.11. Stockholder Rights Plans. If the Company has a stockholder rights
plan in effect upon conversion of the Notes, each Common Share, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Shares issued upon such
conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from
the Common Shares in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Shares
Distributed Property as provided in Section 11.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

ARTICLE 12 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 12.01. Intentionally Omitted. 

Section 12.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any
time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the
“Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 Business Days or more than 35 Business Days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of
the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls
after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular
Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 12. 

(b) Repurchases of Notes under this Section 12.02 shall be made, at the option of the Holder thereof, upon: 

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

  
 56 













 (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 Trustee (or, if at any time the Trustee is not serving as the Paying Agent,
such corporate office or agency as shall be designated by the Paying Agent), or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to
receipt by the Holder of the Fundamental Change Repurchase Price therefor. 
 The Fundamental Change Repurchase Notice in respect of any
Notes to be repurchased shall state: 
 (i) in the case of Physical Notes, the certificate numbers of the Notes to be
delivered for repurchase; 
 (ii) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an
integral multiple thereof; and 
 (iii) that the Notes are to be repurchased by the Company pursuant to the applicable
provisions of the Notes and the Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice
must comply with the procedures of the Depositary in effect at such time. 
 Notwithstanding anything herein to the contrary, any Holder
delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 12.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of
business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 12.03. 

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of
withdrawal thereof. 
 (c) On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company
shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the
Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in
accordance with the applicable procedures of the Depositary. 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; 

  
 57 













 (iii) the last date on which a Holder may exercise the repurchase right
pursuant to this Article 12; 
 (iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

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

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

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

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 12.02. 
 At the Company’s request, the
Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental
Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during 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 12.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be
withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Trustee (or, if at any time the Trustee is not serving as the Paying Agent, such corporate office or agency as shall be
designated by the Paying Agent) in accordance with this Section 12.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 

  
 58 













 (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. 

Section 12.04. Deposit of Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying
Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.03) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an
amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for
Notes surrendered for repurchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date
(provided the Holder has satisfied the conditions in Section 12.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the
manner required by Section 12.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by
wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change
Repurchase Price. 
 (b) If by 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent
appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been properly surrendered for
repurchase and have not been validly withdrawn, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered
to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price and, if applicable, accrued and unpaid interest). 

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 12.02, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered. 

  
 59 













 Section 12.05. Covenant to Comply with Applicable Laws upon Repurchase of Notes.

(b) file a Schedule TO or any other required schedule under the Exchange Act; and

 [FORM OF REVERSE OF NOTE] 

TimkenSteel Corporation 
 6.00%
Convertible Senior Note due 2025 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 6.00% Convertible
Senior Notes due 2025 (the “Notes”), limited to the aggregate principal amount of $[•] all issued or to be issued under and pursuant to the Second Supplemental Indenture dated as of December 15, 2020 (the “Second
Supplemental Indenture”), between the Company and U.S. Bank National Association (the “Trustee”), which amends and supplements the Indenture dated as of May 31, 2016 between the Company and the Trustee (the
“Base Indenture” and, as amended and supplemented by the Second Supplemental Indenture and from time to time with respect to the Notes, the “Indenture”) to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate
principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture. 

In case certain Events of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by
either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set
forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in
respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date 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 (including the
Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money or Common Shares, as the case
may be, herein prescribed. 

  
 A-5 













 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 Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash, Common
Shares or a combination of cash and Common Shares, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
