Article 2
Issue, Description, Execution, Registration and Exchange of Notes

Section 2.01. Designation and Amount. The Notes shall be designated as the “5.00% Senior Convertible Notes due 2026.” The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is initially limited to $350,000,000, subject to Section 2.10 and except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes 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 this Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. In the case of any conflict between this Indenture and a Note, the provisions of this Indenture shall control and govern to the extent of such conflict.

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 this 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 any Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this 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.

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 purchases, 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 this Indenture. Payment of principal (including the Redemption Price and the Fundamental Change Purchase 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; Payments of Interest and Defaulted Amounts(a).

(a) The Notes shall be issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples of $1,000 in excess thereof. Each Note shall be dated the date of its authentication and shall bear interest from the date specified on the face of the form of Note attached as Exhibit A hereto. Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for a partial month, on the basis of the number of days actually elapsed in a 30-day month.

(b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on the Regular Record Date immediately preceding the relevant Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the office or agency of the Company maintained by the Company for such purposes, which shall initially be the Corporate Trust Office. The Company shall pay interest:

(i) on any Certificated Notes (A) to Holders holding Certificated 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 Certificated Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to such Holders or, upon application by such a Holder to the Paying Agent 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 Note Registrar to the contrary; and

(ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee.

(c) 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 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 provided in this clause. 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 (unless the Trustee shall consent to an earlier date). The Company shall promptly notify the Trustee in writing 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 sent 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 sent, 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 and the Depositary if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed reasonably satisfactory to the Trustee.

(iii) The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the Defaulted Amounts, or with respect to the nature, extent, or calculation of the amount of Defaulted Amounts owed, or with respect to the method employed in such calculation of the Defaulted Amounts.

Section 2.04. Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile signature of at least one of its Officers.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes and the documents required under Section 17.06, and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes, without any further action by the Company hereunder.

Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.11), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the Person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be an Officer of the Company, although at the date of the execution of this Indenture any such Person was not such an Officer.

Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note Register”) in which, subject to such reasonable regulations or procedures as it may prescribe, the Company shall provide for the registration of Notes and transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with Section 4.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

All Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed by the Holder thereof or its attorney-in-fact duly authorized in writing.

No service charge shall be imposed by the Company, the Trustee, the Note Registrar or any co-Note Registrar for any registration of transfer or exchange of Notes, but the Company or the Trustee may require a Holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required by law or permitted pursuant to this Indenture.

None of the Company, the Trustee, the Note Registrar or any co-Note 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, (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15 or (iii) any Notes, or a portion of any Note, surrendered for redemption in accordance with Article 16.

All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange.

(a) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fourth paragraph from the end of Section 2.05(b) 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 Certificated Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the Applicable Procedures.

(b) Every Note that bears or is required under this Section 2.05(b) to bear the legend set forth in this Section 2.05(b) (together with any Common Stock issued upon conversion of the Notes and required to bear the legend set forth in Section 2.05(c), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(b) (including the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(b) and Section 2.05(c), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the Issue Date, or such shorter period of time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.05(c), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee):

THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

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

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

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF;

(B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OF THE COMPANY THAT COVERS THE RESALE OF THIS SECURITY OR SUCH COMMON STOCK;

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

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

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been checked.

On any Resale Restriction Termination Date, the Company shall, at its option, deliver to the Trustee a certificate in the form of Exhibit B hereto executed by an Officer of the Company, and upon the Trustee’s receipt of such certificate the restrictive legend required by this Section 2.05(b) shall be deemed removed from any Global Notes representing such Notes without further action on the part of Holders. If the Company delivers such a certificate to Trustee, the Company shall: (i) notify Holders of the Notes that the restrictive legend required by this Section 2.05(b) has been removed or deemed removed; and (ii) instruct the Depositary to change the CUSIP number for the Notes to the unrestricted CUSIP number for the Notes. It is understood that the Depositary of any Global Note may require a mandatory exchange or other process to cause such Global Note to be identified by an unrestricted CUSIP number in the facilities of such Depositary. For the avoidance of doubt, for Notes that are not in certificated form, the Notes shall continue to bear Additional Interest pursuant to this paragraph until such time as they are identified by an unrestricted CUSIP number in the facilities of the Depositary or any successor depositary for the Notes, as a result of completion of the Depositary’s mandatory exchange process or otherwise.

Any Note (or security issued in exchange or substitution therefor) (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(b) and shall not be assigned a restricted CUSIP number.

The Company shall be entitled to instruct the Custodian in writing to so surrender any Global Note as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the restrictive legend specified in this Section 2.05(b) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the Resale Restriction Termination Date and promptly after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(b)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with Applicable Procedures and in compliance with this Section 2.05(b).

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as the “Depositary” with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

If:

(i) the Depositary (A) 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 or (B) ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed within 90 days; or

(ii) there has occurred and is continuing an Event of Default and a beneficial owner of any Note requests through the Depositary that its beneficial interest therein be issued in a Certificated Note,

the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate, an Opinion of Counsel and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver Certificated 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.

Certificated Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(b) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Certificated Notes to the Persons in whose names such Certificated Notes are so registered.

At such time as all interests in a Global Note have been converted, canceled, purchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with Applicable 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 Certificated Notes, converted, canceled, purchased or transferred to a transferee who receives Certificated Notes therefor or any Certificated Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the Applicable Procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

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

(c) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Note shall bear a legend in substantially the following form (unless the Note or such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee and any transfer agent for the Common Stock):

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

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF;

(B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OF THE COMPANY THAT COVERS THE RESALE OF THIS SECURITY OR SUCH COMMON STOCK;

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMMON STOCK RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS.

(d) Any such Common Stock (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by Section 2.05(c).

(e) Any Note that is repurchased or owned by an 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 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 under the Securities Act). 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 members of, or participants in, the Depositary 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.

(f) Neither the Trustee nor any agent of the Trustee shall have any responsibility for any actions taken or not taken by the Depositary.

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

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

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

Section 2.07. Temporary Notes. Pending the preparation of Certificated Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Certificated Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Certificated Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Certificated Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Certificated Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Certificated Notes authenticated and delivered hereunder.

Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, redemption, repurchase (but excluding Notes repurchased pursuant to cash-settled swaps or other derivatives that are not physically settled), registration of transfer or exchange or conversion (subject to the provisions of Section 14.02(j)), if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation, and such Notes shall no longer be considered outstanding for purposes of this Indenture upon their payment, repurchase, registration of transfer or exchange or conversion (subject to the provisions of Section 14.02(j)). All Notes delivered to the Trustee for cancellation shall be cancelled promptly by it. No Notes shall be authenticated in exchange for any Notes cancelled, except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of cancelled Notes in accordance with its customary procedures and, after such disposition, shall deliver evidence of such disposition to the Company, at the Company’s written request in a Company Order. If the Company or any of its Subsidiaries shall acquire any of the Notes, such acquisition shall not operate as a purchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 2.10. Additional Notes; Purchases(a). (a) The Company may, from time to time, without the consent of, or notice to, the Holders, reopen this Indenture and issue additional Notes under this Indenture with the same terms as the Notes issued on the Issue Date (other than differences in the issue date, the issue price and interest accrued prior to the issue date of such additional Notes and, if applicable, the initial Interest Payment Date and restrictions on transfer in respect of such additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes issued on the Issue Date for U.S. federal income tax or securities law purposes, such additional Notes shall have one or more separate CUSIP numbers. Such Notes issued on the Issue Date and the additional Notes shall rank equally and ratably and shall be treated as a single series for all purposes under this Indenture. 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 Section 17.06, as the Trustee shall reasonably request.

(b) The Company may, to the extent permitted by law and without the consent of Holders, 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 private or public tenders or exchange offers or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so purchased (but excluding Notes repurchased pursuant to cash-settled swaps or other derivatives that are not physically settled) to be surrendered to the Trustee for cancellation in accordance with Section 2.08, and they will no longer be considered outstanding under this Indenture upon this repurchase.

Section 2.11. Ranking. The Notes constitute a senior general unsecured obligation of the Company, ranking senior in right of payment to all future indebtedness of the Company that is expressly made subordinate to the Notes by the terms of such indebtedness and ranking equally in right of payment with all existing and future indebtedness of the Company that is not so subordinated.

Article 3

Satisfaction and Discharge

Section 3.01. Satisfaction and Discharge. This Indenture and the Notes shall upon request of the Company contained in an Officer’s Certificate cease (except as set forth in the last paragraph of this Section 3.01) to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when:

(i) either:

(A) all Notes theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust with the Trustee or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d)) have been delivered to the Trustee for cancellation; or

(B) the Company has deposited with the Trustee or delivered to Holders, as applicable, after all of the outstanding Notes have (i) become due and payable, whether at the Maturity Date, upon Redemption or any Fundamental Change Purchase Date, and/or (ii) have been converted (and the related Settlement Amounts have been determined), cash, or solely to satisfy the Company’s Conversion Obligations, cash and/or shares of Common Stock (or if applicable, Reference Property), as applicable, sufficient to pay all of the outstanding Notes and/or satisfy all conversions, as the case may be, and pay all other sums payable under this Indenture by the Company; and

(ii) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 and, if cash or shares of Common Stock shall have been deposited with the Trustee pursuant to Section 3.01(i)(B), Section 4.04 shall survive such satisfaction and discharge.

Article 4

Particular Covenants of the Company

Section 4.01. Payment of Principal, Settlement Amounts and Interest. The Company shall pay or cause to be paid the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, the Settlement Amounts owed on conversion of, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, Settlement Amounts and interest shall be considered paid on the date due if the Paying Agent, if other than the Company, holds as of 11:00 a.m., New York City time, on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, Settlement Amounts and interest then due. Unless such Paying Agent is the Trustee, the Company will promptly notify the Trustee in writing of any failure to take such action.

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) and overdue Settlement Amounts owed on conversion to the extent they include cash, at the rate equal to the interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period), at the same rate to the extent lawful.

Section 4.02. Maintenance of Office or Agency. The Company shall maintain an office or agency (which may be an office of the Trustee or an Affiliate of the Trustee) where Notes may be presented or surrendered for registration of transfer or exchange or for payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. The Company shall, at all times, maintain an office or agency in the continental United States to serve as the Company’s Paying Agent and Conversion Agent for the Notes. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

The Company hereby appoints the Trustee as Paying Agent, Note Registrar, Custodian and Conversion Agent and designates the Corporate Trust Office of the Trustee as one such office or agency of the Company.

The Company reserves the right to vary or terminate the appointment of any Note Registrar, Paying Agent or Conversion Agent, and Bid Solicitation Agent; act as the Paying Agent or Bid Solicitation Agent; appoint additional Paying Agents or Conversion Agents; or approve any change in the office through which any Note Registrar or Paying Agent or Conversion Agent acts.

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

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

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

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

(iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it shall forthwith pay to the Trustee all sums so held in trust.

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

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

(d) Subject to any applicable escheat laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, the Settlement Amounts owed on conversion to the extent they include cash, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable), the Settlement Amounts owed on conversion to the extent they include cash, or interest has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

Section 4.05. [Reserved].

Section 4.06. Rule 144A Information Requirement; Reporting; and Additional Interest(a). (a) For as long as any Notes are outstanding hereunder, at any time the Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issued upon conversion of the Notes shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, upon written request, provide to any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issued upon conversion of the Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or such Common Stock, as the case may be, pursuant to Rule 144A under the Securities Act. The Company shall take such further action as any Holder or beneficial owner of such Notes or such Common Stock, as the case may be, may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or such Common Stock, as the case may be, in accordance with Rule 144A under the Securities Act, as such rule may be amended from time to time.

(b) The Company shall furnish to the Trustee within 15 days after the same are required to be filed with the Commission (after giving effect to any grace period provided by Rule 12b-25 under the Exchange Act or any successor rule under the Exchange Act), copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (excluding any such information, documents or reports, or portions thereof, subject to confidential treatment and any correspondence with the Commission). Any such document or report that the Company files with the Commission via the Commission’s XXXXX system (or any successor thereto) shall be deemed to be furnished to the Trustee for purposes of this Section 4.06(b) as of the time such documents are filed via the XXXXX system (or such successor).

(c) Delivery of the reports, information and documents described in Section 4.06(b) to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants under the Notes or this Indenture (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with such covenants or to determine whether any reports or other documents have been filed with the Commission or the Commission’s XXXXX system (or any successor thereto) or posted on any website or participate in any conference calls.

(d) Subject to Section 6.03(b), if, at any time during the six-month period beginning on, and including, the date that is six months after the Last Original Issue Date, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (other than Current Reports on Form 8-K), after giving effect to all applicable grace periods thereunder, or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were Affiliates of the Company at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. federal securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes from, and including, the first date after the conclusion of the six-month period described above on which such failure to file occurs or the first date the Notes are not otherwise freely tradable as described above by Holders other than the Company’s Affiliates or Holders that were Affiliates of the Company at any time during the three months immediately preceding without restriction pursuant to U.S. federal securities laws or the terms of this Indenture or the Notes, whichever is earlier, until the earlier of (i) the one-year anniversary of the Last Original Issue Date and (ii) the date on which such failure to file has been cured (if applicable) and the Notes are otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were Affiliates of the Company at any time during the three months immediately preceding without restriction pursuant to U.S. federal securities laws or the terms of this Indenture or the Notes. Such Additional Interest shall accrue on the Notes at a rate equal to (i) 0.25% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the date on which such period described in the preceding sentence begins and ending on the 90th day immediately thereafter; and (ii) 0.50% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the 91st day during such period for which the Company’s failure to file has occurred and is continuing or the Notes are not otherwise freely tradeable as described in this Section 4.06(d) by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding).

(e) Subject to Section 4.06(f) and Section 6.03(b), if, and for so long as, the restrictive legend on the Notes specified in Section 2.05(b) has not been removed (or deemed removed), the Notes are assigned a restricted CUSIP number or the Notes are not otherwise freely tradable as described in Section 4.06(d) by Holders other than the Company’s Affiliates or Holders that were Affiliates of the Company at any time during the three months immediately preceding without restrictions pursuant to U.S. federal securities law or the terms of this Indenture or the Notes as of the 380th day after the Issue Date, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the restrictive legend on the Notes specified in Section 2.05(b) has been removed (or deemed removed), the Notes are assigned an unrestricted CUSIP number and the Notes are freely tradable as described in Section 4.06(d) by Holders other than the Company’s Affiliates or Holders that were Affiliates of the Company at any time during the three months immediately preceding without restrictions pursuant to U.S. federal securities laws or the terms of this Indenture or the Notes. The restrictive legend on the Notes shall be deemed removed pursuant to the terms of this Indenture upon notice by the Company to the Trustee and delivery of the documents required pursuant to this Indenture, and, at such time, the Notes will be automatically assigned an unrestricted CUSIP. However, for the avoidance of doubt, for Notes that are not in certificated form, the Notes shall continue to bear Additional Interest pursuant to this Section 4.06(e) until such time as such Notes are identified by an unrestricted CUSIP in the facilities of the Depositary as a result of completion of the Depositary’s mandatory exchange process or otherwise.

(f) Additional Interest, which shall constitute the sole remedy relating to the failure to comply with the Company’s obligations under this Section 4.06, shall be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes and shall be in addition to any Additional Interest that may accrue, at the Company’s election, pursuant to Section 6.03. In no event, however, shall Additional Interest accrue on any day (taking into consideration any Additional Interest payable as described in Section 4.06(d), Section 4.06(e) and Section 6.03(a)) at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

(g) If Additional Interest is payable by the Company pursuant to Section 4.06(d), Section 4.06(e) or Section 6.03(a), the Company shall deliver to the Trustee an Officer’s Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable.

Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.08. Compliance Certificate; Statements as to Defaults.

(a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year (beginning with the year ended December 31, 2019), an Officer’s Certificate indicating whether the signers thereof have knowledge of any Default that occurred during the previous year and is then continuing and, if so, specifying each such failure and the nature thereof.

(b) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee an Officer’s Certificate within 30 days after an Officer of the Company becomes aware of the occurrence of any event that would constitute a Default or Event of Default, specifying each such event, the status thereof and what action the Company is taking or proposes to take with respect thereto.

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

Section 4.10. No Rights as Stockholders. Holders of Notes, as such, will not have any rights as stockholders of the Company (including, without limitation, voting rights and rights to receive any dividends or other distributions on Common Stock).

(d) a failure by the Company to comply with its obligation to convert the Notes in accordance with the provisions of this Indenture upon exercise of a Holder’s conversion right and such default shall continue for a period of three Business Days after there has been given, by registered or certified mail, to the Company by the Trustee or by such Holder, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” under this Indenture;

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

Section 6.02. Acceleration. In case one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(g) or Section 6.01(h) with respect to the Company), either the Trustee by notice in writing to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, may declare 100% of the principal of, and accrued and unpaid interest, if any, on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable. If an Event of Default specified in Section 6.01(g) or Section 6.01(h) with respect to the Company 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, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes.

Section 6.03. Additional Interest.

(a) Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall, after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to (i) 0.25% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the date on which such Event of Default first occurred and ending on the 180th day immediately following, and including, the date on which such Event of Default first occurred; and (ii) if such Event of Default has not been cured or validly waived prior to the 181st day immediately following, and including, the date on which such Event of Default first occurred, 0.50% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the 181st day immediately following, and including, the date on which such Event of Default first occurred and ending on the 365th day immediately following, and including, the date on which such Event of Default first occurred (in addition to any Additional Interest that may accrue as a result of a default pursuant to Sections 4.06(d) and 4.06(e)).

(b) Any Additional Interest payable pursuant to Section 6.03(a) shall be in addition to any Additional Interest that may accrue pursuant to Sections 4.06(d) and 4.06(e). Notwithstanding anything in this Indenture to the contrary, in no event, however, shall Additional Interest accrue (taking into consideration any Additional Interest payable pursuant to Section 6.03(a), together with Additional Interest payable pursuant to Sections 4.06(d) and 4.06(e)) on any day at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

(c) If the Company elects to pay Additional Interest pursuant to Section 6.03(a), such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes and will accrue on all Notes then outstanding from, and including, the date on which the Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) first occurs to, but not including, the 366th day thereafter (or such earlier date on which such Event of Default is cured or waived by the Holders of a majority in principal amount of the Notes then outstanding). On the 366th day after such Event of Default (if such Event of Default is not cured or waived prior to such 366th day), such Additional Interest will cease to accrue and the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Additional Interest following an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) in accordance with this Section 6.03, or the Company elects to make such payment but does not pay the Additional Interest when due, the Notes shall immediately be subject to acceleration as provided in Section 6.02. For the avoidance of doubt, the provisions of this Section 6.03 shall not affect the rights of Holders in the event of the occurrence of any other Event of Default.

(d) In order to elect to pay Additional Interest as the sole remedy during the 365 days after the occurrence of an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b), the Company must notify, in writing, all Holders of the Notes, the Trustee and the Paying Agent (if other than the Trustee) of such election on or before the close of business on the date on which such Event of Default first occurs. Upon the Company’s failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in Section 6.01 (a), (b) or (d) shall have occurred and the Notes have become due and payable pursuant to Section 6.02, 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 (including the Redemption Price and the Fundamental Change Purchase Price, if applicable), satisfaction of the Conversion Obligation with respect to all Notes that have been converted, and interest, if any, with (to the extent that payment of such interest shall be legally enforceable) interest on any such overdue amounts, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company under Bankruptcy Law, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company, the property of the Company, or in the event of any other judicial proceedings relative to the Company, or to the creditors or property of the Company, the Trustee, irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company, its creditors, or its property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

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

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

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

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver, rescission or annulment pursuant to Section 6.09 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though no such proceeding had been instituted.

Section 6.05. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

FIRST: to the payment of all amounts due the Trustee under Section 7.06;

SECOND: to the payment of the amounts then due and unpaid for principal of, the Redemption Price and Fundamental Change Purchase Price (if applicable) of, and/or satisfaction of the Conversion Obligation with respect to all Notes that have been converted, and interest on the Notes in respect of which or for the benefit of which such money has been collected, ratably,without preference or priority of any kind, according to the amounts due and payable on such Notes; and

THIRD: to the Company.

Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the Redemption Price and the Fundamental Change Purchase Price) or interest when due, or the right to receive payment and/or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(a) such Holder has previously given the Trustee written notice that an Event of Default is continuing;

(b) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy;

(c) such Holders have offered the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability, claim or expense;

(d) the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of such security or indemnity; and

(e) the Holders of a majority in principal amount of the then outstanding Notes have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder, it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any actions or forbearances by a Holder are unduly prejudicial to other Holders.

Notwithstanding any other provision of this Indenture and any provision of any Note, the contractual right of any Holder to institute suit for the enforcement of any payment of (x) principal (including, if applicable, the Redemption Price and the Fundamental Change Purchase Price), (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon the conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, and such contractual right shall not be impaired or affected without the consent of such Holder.

Section 6.07. Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

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

Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders.

(a) The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (i) such direction shall not be in conflict with any rule of law or with this Indenture, and (ii) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that conflicts with any rule of law or with this Indenture, it determines is unduly prejudicial to the rights of any other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such Holders) or that would involve the Trustee in personal liability.

(b) 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 rescind any acceleration with respect to the Notes and its consequences hereunder except:

(i) a default in the payment of the principal (including the Redemption Price and any Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest, if any, on the Notes;

(ii) a failure by the Company to deliver the consideration due upon conversion of the Notes; or

(iii) with respect to any other provision that requires the consent of each affected Holder pursuant to Section 10.02 to amend;

provided that, in the case of the rescission of any acceleration with respect to the Notes, (1) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default (other than the nonpayment of the principal of and interest on the Notes that have become due solely by such declaration of acceleration) have been cured or waived and all amounts owing to the Trustee have been paid.

Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section 6.10. Notice of Defaults. If a Default occurs and is continuing and is actually known to¹ a Responsible Officer of the Trustee (who, for the avoidance of doubt, is entitled to receive notice from the Company in accordance with Section 4.08(b)), the Trustee shall deliver to all Holders as the names and addresses of such Holders appear upon the Note Register notice of such Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) or accrued and unpaid interest, if any, on any Note or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

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

The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee.

Section 7.07. [Reserved].

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

Section 7.09. Resignation or Removal of Trustee. The Trustee may at any time resign by giving 30 days prior written notice of such resignation to the Company and by mailing notice thereof to the Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon five Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

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

(i) the Trustee shall fail to comply with Section 7.13 within a reasonable time after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months;

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(iii) the Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

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

(b) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time, with 30 days prior written notice to the Trustee and the Company, remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after removal of the Trustee by the Holders, the Trustee may, at the expense of the Company, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor trustee.

(c) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 7.09 shall become effective upon (i) payment of all fees and expenses owing to the Trustee and (ii) acceptance of appointment by the successor trustee as provided in Section 7.10.

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

No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08.

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall send or cause to be sent notice of the succession of such trustee hereunder to the Holders at their addresses as they shall appear on the Note Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

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

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

Section 7.12. Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any Officer 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 date of effectiveness in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted.

Section 7.13. Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of this Indenture.

Article 8
Concerning the Holders

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

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

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

Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Affiliate of the Company or any Subsidiary thereof shall be disregarded (from both the numerator and the denominator) and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or any Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

Section 10.02. Supplemental Indentures with Consent of Holders. Except as provided in Section 10.01 and in this Section 10.02, the Company and the Trustee may from time to time and at any time amend or supplement this Indenture and the Notes with the consent (evidenced as provided in Article 8) of the Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes) and any existing Default or Event of Default (other than (i) a Default or Event of Default in the payment of the principal (including any Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded, and (ii) a Default or Event of Default as a result of a failure by the Company to deliver the consideration due upon conversion of the Notes) or compliance with any provision of this Indenture or the Notes may be waived with the consent (evidenced as provided in Article 8) of the Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes); provided, however, that, without the consent of each Holder of an outstanding Note affected, no such amendment shall:

(a) reduce the amount of Notes whose Holders must consent to an amendment, supplement or waiver;

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

(c) reduce the principal amount of any Note (including, without limitation, the principal payable upon acceleration thereof) or extend the Maturity Date of any Note;

(e) reduce the Fundamental Change Purchase Price or the Redemption Price of any Note or amend or modify in any manner adverse to the Holders the Company’s obligation to make such payments, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise;

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

(g) change the ranking of the Notes;

(i) make any change in this Article 10 that requires each Holder’s consent or in the waiver provisions (including in Section 6.09).

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the Company in the execution of such amendment, supplement or waiver unless such amendment, supplement or waiver adversely affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amendment, supplement or waiver.

Holders do not need under this Section 10.02 to approve the particular form of any proposed amendment, supplement or waiver of this Indenture. It shall be sufficient if such Holders approve the substance thereof. After any such amendment, supplement or waiver becomes effective, the Company shall send to the Holders a notice briefly describing such amendment, supplement or waiver, unless a Current Report on Form 8-K (or successor form thereto) is filed by the Company describing the amendment, supplement or waiver. 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 amendment, supplement or waiver.

Section 10.03. Effect of Amendment, Supplement and Waiver. Upon the execution of any amendment, supplement or waiver of this Indenture pursuant to the provisions of this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such amendment or supplement shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 10.04. Notation on Notes. Notes authenticated and delivered after the execution of any amendment, supplement or waiver to this Indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such amendment, supplement or waiver. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such amendment, supplement or waiver may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.11) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 10.05. Evidence of Compliance of Amendment, Supplement or Waiver to Be Furnished to Trustee. In addition to the documents required by Section 17.06, the Trustee shall receive and may rely on an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any amendment, supplement or waiver to this Indenture executed pursuant hereto complies with the requirements of this Article 10, is permitted or authorized by this Indenture and such amendment, supplement or waiver is the legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms.

Article 11
Consolidation, Merger and Sale

Section 11.01. Company May Consolidate, Etc. on Certain Terms.

(a) The Company shall not, in a single transaction or through a series of related transactions, consolidate or merge with or into any other Person, or directly or indirectly, sell, lease, convey or otherwise transfer or dispose of all or substantially all of its assets (as defined below), to another Person or group of affiliated Persons, except that the Company may consolidate or merge with, or sell or convey substantially all of its assets to another Person if:

(i) the Company is the continuing corporation or the successor Person (if other than the Company) (the “Successor Company”) is a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and such Successor Company expressly assumes by supplemental indenture all of the Company’s obligations under the Notes and this Indenture, including payment of the principal and interest on the Notes and the performance and observance of all of the covenants and conditions of this Indenture to be performed by the Company;

(ii) the Company delivers an Officer’s Certificate and Opinion of Counsel (which may rely upon such Officer’s Certificate to the absence of Defaults and Events of Default and other statements of fact) each stating that all conditions precedent herein relating to such consolidation, merger or sale of assets have been complied with; and

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

For purposes of this Section 11.01 only, “substantially all of its assets” shall mean, as of any date, a portion of the non-current assets reflected in the Company’s consolidated balance sheet as of the end of the most recent quarterly period that represents at least 66% of the total reported value of such assets.

(b) Upon any such consolidation, merger, combination or sale, lease or other transfer or disposition 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 and/or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture and the Notes to be performed by the Company, such Successor Company shall succeed to, and may exercise every right and power of and be substituted for, the Company, with the same effect as if it had been named herein as the party of the first part, and the Company shall be discharged from its obligations under the Notes and this Indenture, except in the case of a lease of all or substantially all assets. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall 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 this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, combination or sale, transfer or disposition (but not in the case of a lease), upon compliance with this Article 11, the Person named as the “Company” in the first paragraph of this Indenture shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes.

Article 14
Conversion of Notes

Section 14.01. Conversion Privilege.

(a) Subject to and upon compliance with the provisions of this Article 14, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple of $1,000 in excess thereof) of such Note:

(i) subject to satisfaction of the conditions described in Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding August 1, 2026 under the circumstances and during the periods set forth in Section 14.01(b);

(ii) on or after August 1, 2026, at any time prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date;

in each case, at an initial conversion rate of 74.8391 shares of Common Stock (subject to adjustment as provided in Section 14.04 and, if applicable, Section 14.03, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 14.02, the “Conversion Obligation”).

(b) (i) Prior to the close of business on the Business Day immediately preceding August 1, 2026, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period 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 the procedures and conditions described in this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading Day, subject to compliance with the following procedures and conditions concerning the Bid Solicitation Agent’s obligation to make a Trading Price determination.

(A) The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of the Notes unless the Company has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day. At such time, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of the Notes beginning on the Trading Day following the receipt of such evidence and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day.

(B) If the Trading Price condition has been met on any trading day, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing. If, at any time after the Trading Price condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day, the Company shall promptly so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing.

(C) If the Company does not, when it is required to, instruct the Bid Solicitation Agent to (or, if the Company is acting as Bid Solicitation Agent, it does not) obtain bids, or if the Company gives such instruction to the Bid Solicitation Agent and the Bid Solicitation Agent fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of the Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure.

(ii) If, prior to the close of business on the Business Day immediately preceding August 1, 2026, the Company elects to:

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

(B) distribute to all or substantially all holders of the Common Stock the Company’s assets, securities or rights, options or warrants to purchase securities of the Company (other than in connection with a stockholder rights plan), which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of announcement of such distribution,

then, in either case, the Company shall notify all Holders of the Notes at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, the Holders may surrender all or any portion of their 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.

(iii) If, prior to the close of business on the Business Day immediately preceding August 1, 2026:

(A) a transaction or event that constitutes a Fundamental Change occurs;

(B) a transaction or event that constitutes a Make-Whole Fundamental Change occurs; or

(C) the Company is a party to a statutory share exchange, consolidation, merger, or other similar transaction or sale, lease or other transfer or disposition of all or substantially all of the Company’s consolidated assets, taken as a whole, in each case, pursuant to which the Common Stock would be converted into cash, securities or other property,

then, in each case, a Holder may surrender all or any portion of its Notes for conversion at any time from or after the open of business on the effective date of such transaction until the close of business on the 35th Trading Day after the effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the close of business on the Business Day immediately preceding the related Fundamental Change Purchase Date.

If a Holder has already delivered a Fundamental Change Purchase Notice with respect to a Note, such Holder may not surrender such Note for conversion until such Holder has validly withdrawn such Fundamental Change Purchase Notice (or, in the case of a Global Note, has complied with the Applicable Procedures with respect to such a withdrawal) in accordance with the terms of Section 15.03. If a Holder has already delivered a Fundamental Change Purchase Notice, such Holder’s right to withdraw such notice and convert the Notes that are subject to required purchase will terminate at the close of business on the Business Day immediately preceding the relevant Fundamental Change Purchase Date.

The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the effective date of any such transaction as promptly as practicable following the date the Company publicly announces such transaction; provided that the Company shall deliver such notice, to the extent practicable, at least 30 Scheduled Trading Days prior to the anticipated effective date of such transaction and in no event later than the actual effective date.

(iv) Prior to the close of business on the Business Day immediately preceding August 1, 2026, a Holder may surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on December 31, 2019 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day.

(v) If the Company calls the Notes for Redemption pursuant to Section 16.01, Holders may submit for conversion any or all of their Notes called for Redemption at any time from, and including the Redemption Notice Date until the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date, or if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides for the Redemption Price.

Section 14.02. Conversion Procedure; Settlement Upon Conversion.

(a) Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall, at its election, pay or deliver, as the case may be, to the converting Holder, in full satisfaction of its Conversion Obligation, cash (“Cash Settlement”), shares of the Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with Section 14.02(i) (“Physical Settlement”), or a combination of cash and shares of the Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with Section 14.02(i) (“Combination Settlement”), as set forth in this Section 14.02.

(i) All conversions for which the relevant Conversion Date occurs on or after August 1, 2026 and all conversions for which the Conversion Date occurs on or after the Redemption Notice Date and prior to the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date shall be settled using the same Settlement Method (including the same relative proportion of cash and/or shares of the Common Stock). Except for any conversions for which the relevant Conversion Date occurs on or after August 1, 2026 and all conversions for which the Conversion Date occurs on or after the Redemption Notice Date and prior to the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date, the Company shall use the same Settlement Method (including the same relative proportion of cash and/or shares of the Common Stock) for all conversions that occur on the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates.

(ii) If the Company elects a Settlement Method, the Company shall deliver notice to Holders so converting through the Conversion Agent of such Settlement Method the Company has selected no later than the close of business on the VWAP Trading Day immediately following the related Conversion Date (or (i) in the case of any conversions for which the relevant Conversion Date occurs on or after August 1, 2026, no later than August 1, 2026 or (ii) in the case of any conversions occurring on or after the date of a Notice of Redemption and prior to the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date, in such Notice of Redemption). If the Company does not timely elect a Settlement Method, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement with respect to that Conversion Date 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. If the Company has timely elected Combination Settlement in respect of any conversion but does not timely notify the Conversion Agent of the Specified Dollar Amount per $1,000 principal amount of Notes, the Specified Dollar Amount shall be deemed to be $1,000.

(iii) The cash, shares of Common Stock or combination of cash and shares of Common Stock payable or deliverable by the Company in respect of any conversion of Notes (the “Settlement Amount”) shall be computed by the Company as follows:

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock equal to the Conversion Rate on the Conversion Date (plus cash in lieu of any fractional share of Common Stock issuable upon conversion);

(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 20 consecutive VWAP Trading Days during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 principal amount of Notes being converted a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive VWAP Trading Days during the related Observation Period (plus cash in lieu of any fractional share of Common Stock issuable upon conversion).

If more than one Note shall be surrendered for conversion at any 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 hereby) so surrendered.

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

(b) (i) To convert a beneficial interest in a Global Note (which conversion is irrevocable), the holder of such beneficial interest must:

(A) comply with the Applicable Procedures;

(B) if required, pay funds equal to all documentary, stamp or similar issue or transfer tax owed as set forth in Section 14.02(d) and Section 14.02(e); and

(C) if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(g); and

(ii) To convert a Certificated Note, the Holder must:

(A) 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”) and such Note to the Conversion Agent;

(B) if required, furnish appropriate endorsements and transfer documents;

(C) if required, pay funds equal to all documentary, stamp or similar issue or transfer tax owed as set forth in Section 14.02(d) and Section 14.02(e); and

(D) if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(g).

The Trustee (and if different, the Conversion Agent), upon receiving notice of any conversion, shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion or, if notice on such date is not feasible given the nature of the conversion, promptly thereafter.

If a Holder has already delivered a Fundamental Change Purchase Notice with respect to a Note, such Holder may not surrender such Note for conversion until such Holder has validly withdrawn such Fundamental Change Purchase Notice (or, in the case of a Global Note, has complied with the Applicable Procedures with respect to such a withdrawal) in accordance with the terms of Section 15.03. If a Holder has already delivered a Fundamental Change Purchase Notice, such Holder’s right to withdraw such notice and convert the Notes that are subject to repurchase will terminate at the close of business on the Business Day immediately preceding the relevant Fundamental Change Purchase Date.

If the Company has designated a Redemption Date pursuant to Section 16.02, a Holder that complies with the requirements for conversion set forth in this Section 14.02(b) shall be deemed to have delivered a notice of its election not to have its Notes so redeemed.

(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 Section 14.02(b).

Subject to the next paragraph and the provisions of Section 14.03(b) and Section 14.07(a), the Company shall pay or deliver, as the case may be, the Settlement Amount due in respect of the Conversion Obligation no later than:

(i) the second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement; or

(ii) the second Business Day immediately following the last VWAP Trading Day of the relevant Observation Period, if the Company elects Cash Settlement or if the Company elects or is deemed to elect Combination Settlement.

If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary, as the case may be, for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

(d) In case any Certificated Note shall be surrendered for partial conversion, in $1,000 principal amount or an integral multiple of $1,000 in excess thereof, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion.

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

(f) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian of the Global Note at the direction of the Trustee, shall make a notation in the books and records of the Trustee and Depositary 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.

(g) Upon conversion of a Note, the converting Holder shall not receive any separate cash payment representing accrued and unpaid interest, if any, except as set forth in the paragraph below. The Company’s payment or delivery, as the case may be, of the Settlement Amount upon conversion of any Note shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than canceled, extinguished or forfeited (other than in the circumstances described under Section 14.01(b)(v)). Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first out of the cash paid upon such conversion.

Notwithstanding the immediately preceding paragraph, if Notes are converted after the close of business on a Regular Record Date for the payment of interest and prior to the open of business on the immediately following Interest Payment Date, Holders of such Notes at the close of business on such Regular Record Date shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted on the corresponding Interest Payment Date (regardless of whether the converting Holder was the Holder of record on the corresponding Regular Record Date); provided that no such payment need be made:

(i) if the Notes are surrendered for conversion following the Regular Record Date immediately preceding the Maturity Date;

(ii) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date;

(iii) if the Company has specified a Redemption Date in accordance with Article 16 that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or

(iv) to the extent of any overdue interest, if any overdue interest exists 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 and any Fundamental Change Purchase Date as described in clause (ii) above, shall receive and retain the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been converted following such Regular Record Date.

(h) The Person in whose name any shares of Common Stock shall be issuable upon conversion is registered shall be treated as the holder of record of such shares as of the close of business on (i) the relevant Conversion Date if the Company elects Physical Settlement or (ii) the last VWAP Trading Day of the relevant Observation Period if the Company elects or is deemed to elect Combination Settlement. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion; provided that (a) the converting Holder shall have the right to receive the Settlement Amount due upon conversion and (b) in the case of a conversion between a Regular Record Date and the corresponding Interest Payment Date, the Holder of record as of the close of business on such Regular Record Date shall have the right to receive the interest payable on such Interest Payment Date, in accordance with Section 14.02(g).

(i) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion in an amount based on (i) the Daily VWAP on the relevant Conversion Date if the Company elects Physical Settlement or (ii) the Daily VWAP on the last VWAP Trading Day of the relevant Observation Period if the Company elects or is deemed to elect Combination Settlement. For each Note surrendered for conversion, if the Company has elected (or is deemed to elect) Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and, if applicable, any fractional share remaining after such computation shall be paid in cash.

(j) Upon surrender by a Holder of its Notes for conversion, the Company may, at its election (an “Exchange Election”), direct the Conversion Agent to surrender, on or prior to the Scheduled Trading Day immediately preceding the first VWAP Trading Day of the applicable Observation Period (or, if we have elected physical settlement, on or prior to the Business Day immediately following the relevant Conversion Date), such Notes to a financial institution designated by the Company (the “Designated Financial Institution”) for exchange in lieu of conversion by the Company. In order to accept any Notes surrendered to the Company for conversion, the Designated Financial Institution must agree to timely deliver, in exchange for such Notes, cash, shares of Common Stock or combination thereof, at the Company’s election, that would otherwise be due upon conversion, all as provided in Section 14.02(a) (the “Conversion Consideration”). If the Company makes an Exchange Election, the Company shall, by the close of business on the Scheduled Trading Day immediately preceding the first VWAP Trading Day of the applicable Observation Period (or, if we have elected physical settlement, on or prior to the Business Day immediately following the relevant Conversion Date), notify in writing the Holder surrendering Notes for conversion and the Trustee that the Company has made an Exchange Election and shall notify the Designated Financial Institution of the Settlement Method the Company has elected with respect to such conversion and the relevant deadline for delivery of the relevant Conversion Consideration.

If the Designated Financial Institution accepts any such Notes, it will pay and/or deliver, as the case may be, the cash, shares of Common Stock or a combination thereof due upon conversion to the Conversion Agent, and the Conversion Agent shall pay and/or deliver such cash and/or shares of Common Stock to such Holder the second Business Day immediately following the last VWAP Trading Day of the applicable Observation Period (or if we have selected physical settlement, on the second Business Day immediately following the relevant Conversion Date). Any Notes exchanged by the Designated Financial Institution shall remain outstanding, subject to the Applicable Procedures. If the Designated Financial Institution agrees to accept any Notes for exchange but does not timely deliver the related Conversion Consideration, or if such Designated Financial Institution does not accept the Notes for exchange, the Company shall convert the Notes and deliver the relevant Conversion Consideration as described in this Section 14.02.

The Company’s designation of a Designated Financial Institution does not require such Designated Financial Institution to accept any Notes. The Company may, but shall not be obligated to, enter into a separate agreement with any Designated Financial Institution that would compensate it for any such transaction.

Section 14.03. Increase in Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change or a Notice of Redemption. (a) If (i) the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date or (ii) on or after November 5, 2023, the Company gives a Notice of Redemption pursuant to Section 16.02, and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or a Notice of Redemption, as the case may be, the Company shall, under the circumstances described in this Section 14.03, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described in this Section 14.03. 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 (or, in the case of a Global Note, the relevant notice of conversion in accordance with the Applicable Procedures) is received by the Conversion Agent during the period from the open of business on the Effective Date of the Make-Whole Fundamental Change to the close of business on the Business Day immediately preceding the related Fundamental Change Purchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). A conversion of Notes shall be deemed to be “in connection with” a Notice of Redemption if the relevant Conversion Date occurs during the period from the open of business on the Redemption Notice Date to the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date or, if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides for the Redemption Price.

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy its Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.02 (after giving effect to any increase in the Conversion Rate required by this Section 14.03); provided, however, that, if the consideration for the Common Stock in any Make-Whole Fundamental Change described in clause (b) of the definition of 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 by the Company based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to (i) the Conversion Rate (including any increase to reflect the Additional Shares as described in this Section 14.03), multiplied by (ii) such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole Fundamental Change and no later than five Business Days after such Effective Date issue a press release announcing such Effective Date (and make the press release available on the Company’s website) (the “Make-Whole Fundamental Change Company Notice”).

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective or the Redemption Notice Date, as the case may be (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change or on the case of a Redemption, pursuant to Article 16. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, and in the case of a conversion upon Notice of Redemption, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change or the Redemption Notice Date, as the case may be. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, during such five Trading Day period.

(d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate is otherwise adjusted. The adjusted Stock Prices shall equal (i) the Stock Prices applicable immediately prior to such adjustment, multiplied by (ii) a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 14.04.

(e) The following table sets forth the number of Additional Shares by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date set forth below:

	Stock Price
Effective Date	$10.48		$12.00		$13.36		$15.00		$17.37		$20.00		$25.00		$30.00		$35.00		$40.00		$45.00		$50.00

The exact Stock Price or Effective Date may not be set forth in the table above, in which case:

(i) if the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares by which the Conversion Rate shall be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates in the table above, as applicable, based on a 365- or 366-day year, as the case may be;

(ii) if the Stock Price is greater than $50.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $10.48 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 95.4198 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04.

(f) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04 in respect of a Make-Whole Fundamental Change.

Section 14.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to (i) the Conversion Rate, multiplied by (ii) the principal amount (expressed in thousands) of Notes held by such Holder.

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

where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as applicable;

CR₁	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or effective date, as applicable;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date, as applicable; and

OS₁	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such ex-dividend date or effective date after giving effect to such dividend, distribution, share split or share combination, as applicable.

Any adjustment made under this Section 14.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

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

where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR₁	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;

X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y	=	the number of shares of Common Stock equal to (i) the aggregate price payable to exercise such rights, options or warrants, divided by (ii) the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the announcement date of the distribution of such rights, options or warrants.

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

For purposes of this Section 14.04(b) and Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders of Common Stock to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the announcement date of such distribution, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding:

(i) Dividends or distributions as to which an adjustment was effected pursuant to Section 14.04(a) or Section 14.04(b);

(ii) rights issued under a stockholders rights plan (except as set forth in this Section 14.04(c));

(iii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 14.04(d);

(iv) any dividends and distributions in connection with a Share Exchange Event described in Section 14.07; and

(v) Spin-Offs as to which the provisions set forth in this Section 14.04(c) shall apply

(any of such shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR₁	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV	=	the fair market value (as determined by the Board of Directors) of the Distributed Property so distributed with respect to each outstanding share of the Common Stock as of the open of business on the Ex-Dividend Date for such distribution.

Any increase made under the portion of this Section 14.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.

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

where,

CR₀	=	the Conversion Rate in effect immediately prior to the end of the Valuation Period;

CR₁	=	the Conversion Rate in effect immediately after the Valuation Period;

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

MP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

The increase to the Conversion Rate under the preceding paragraph shall occur at the close of business on the last Trading Day of the Valuation Period; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, the references to “10” in the preceding paragraph 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, the references to “10” in the preceding paragraph 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. In addition, if the Ex-Dividend Date for such 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 to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion, 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. If such Spin-Off does not occur, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared, effective as of the date on which the Board of Directors (or its designee) determines not to consummate such Spin-Off.

For purposes of this Section 14.04(c) (and subject in all respect to Section 14.11), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”):

(i) are deemed to be transferred with such shares of the Common Stock;

(ii) are not exercisable; and

(iii) are also issued in respect of future issuances of the Common Stock,

shall be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was made:

(A) 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 shares of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of shares of Common Stock as of the date of such redemption or purchase, and

(B) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

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

(i) a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the “Clause A Distribution”); or

(ii) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable (the “Clause B Distribution”),

then:

(A) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 14.04(c) with respect to such Clause C Distribution shall then be made; and

(B) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date” within the meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b).

(d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, other than a regular, quarterly cash dividend that does not exceed $0.05 per share (the “Initial Dividend Threshold”), the Conversion Rate shall be adjusted based on the following formula:

where,

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

CR₁	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

SP₀	=	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;

T	=	the Initial Dividend Threshold; provided that if the dividend or distribution is not a regular quarterly cash dividend, the Initial Dividend Threshold shall be deemed to be zero; and

C	=	the amount in cash per share the Company distributes to all holders of the Common Stock.

The Initial Dividend Threshold is subject to adjustment in a manner inversely proportional to adjustments to the Conversion Rate; provided that no adjustment will be made to the Initial Dividend Threshold for any adjustment to the Conversion Rate under this Section 14.04(d).

Any increase made pursuant to this Section 14.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such cash dividend or distribution.

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

where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the Expiration Date;

CR₁	=	the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the Expiration Date;

AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to consummation of the purchase of all shares of Common Stock accepted for purchase or exchange in such tender offer or exchange offer;

OS₁	=	the number of shares of Common Stock outstanding immediately after consummation of the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer; and

SP₁	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

The increase to the Conversion Rate under this Section 14.04(e) shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires but will be given effect at the open of business on the Trading Day next succeeding the Expiration Date; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between such Expiration Date of such tender or exchange offer and the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed to be 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 Expiration Date of any tender or exchange offer is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date of such tender or exchange offer to, and including, last Trading Day of such Observation Period. For the avoidance of doubt, no adjustment shall be made under this Section 14.04(e) if such adjustment would result in a decrease to the Conversion Rate.

In the event that the Company or one of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that have been effected.

(f) Notwithstanding anything to the contrary in this Section 14.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 14.02(h) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) All calculations and other determinations under this Article 14 shall be made by the Company and all adjustments to the Conversion Rate shall be made to the nearest one-ten thousandth (1/10,000th) of a share. Notwithstanding anything in this Article 14 to the contrary, the Company shall not be required to adjust the Conversion Rate if the adjustment would result in a change of less than 1.0% to the Conversion Rate, and the Company may, at its election, defer such adjustment and carry forward any adjustment to Conversion Rate that the Company would otherwise have had to make and take into account such deferred adjustment in any subsequent adjustment. Notwithstanding the foregoing, any and all such deferred adjustments must be given effect immediately upon the earliest of the following, regardless of whether the aggregate amount of such adjustments is less than 1.0%: (a) on the Conversion Date for any Notes (in the case of Physical Settlement) or on each VWAP Trading Day of any Observation Period (in the case of cash settlement or combination settlement), (b) the effective date of any Fundamental Change or the Effective Date of a Make-Whole Fundamental Change, (c) on the Redemption Notice Date, or (d) November 1, 2026.

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, 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, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall send to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly furnish to 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 send such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of this Indenture. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(j) For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

(k) The Company shall not adjust the Conversion Rate except as stated in this Indenture, including, for the avoidance of doubt, for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. In addition, notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be adjusted:

(i) upon the issuance of shares of Common Stock (other than issuances described in clause (a), (b), or (c) of this Section 14.04) at a price below the Conversion Price for the Notes;

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

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

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

(v) for ordinary course of business stock repurchases that are not tender offers referred to in Section 14.04(e), including structured or derivative transactions or pursuant to a stock repurchase program approved by the Board of Directors;

(vi) for a third party tender offer by any party other than a tender offer by the Company or any of its Subsidiaries described in clause (e) of this Section 14.04;

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

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

Section 14.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

Section 14.06. Shares to Be Fully Reserved. The Company shall have reserved and shall provide, free from preemptive rights, out of its authorized but unissued shares, the maximum number of shares of Common Stock issuable upon conversion of the Notes (assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement is applicable, and including the maximum number of Additional Shares that could be included in the Conversion Rate for a conversion in connection with a Make-Whole Fundamental Change or a Notice of Redemption).

Section 14.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock.

(a) In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination);

(ii) any statutory share exchange, consolidation, merger or similar transaction; or

(iii) any sale, lease or other transfer or similar transaction in one transaction or a series of transactions of all or substantially all of the Company’s and its Subsidiaries’ consolidated assets, taken as a whole, to any person other than one or more of the Company’s Subsidiaries.

in each case, as a result of which the Common Stock would be converted into, or exchanged for cash, securities or other property (any such event, a “Share Exchange Event” and any such cash, securities or other property (including any combination thereof), “Reference Property” and the amount of Reference Property that a holder of one share of the Common Stock immediately prior to such Share Exchange Event would have been entitled to receive upon the occurrence of such Share Exchange Event, a “Unit of Reference Property”), then the Company, or the successor or purchasing corporation, as the case may be, will execute with the Trustee, without the consent of the Holders, a supplemental indenture providing that, at and after the effective time of the Share Exchange Event, the right to convert each $1,000 principal amount of Notes will be changed into a right to convert such principal amount of Notes into the kind and amount of Reference Property that a holder of a number of shares of the Common Stock equal to the Conversion Rate immediately prior to such Share Exchange Event would have been entitled to receive upon such Share Exchange Event; provided, however, that at and after the effective time of such Share Exchange Event:

(A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 14.02; and

(B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the Units of Reference Property that a holder of that number of shares of Common Stock would have received in such Share Exchange Event and (III) the Daily VWAP shall be calculated based on the value of a Unit of Reference Property; provided, however, that if the holders of Common Stock receive only cash in such Share Exchange Event, then for all conversions that occur after the effective date of such Share Exchange Event (x) the consideration due upon conversion of each $1,000 principal aggregate amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.03), multiplied by the price paid per share of Common Stock in such Share Exchange Event and (y) the Company shall satisfy the Conversion Obligation by paying such cash to the converting Holder on the second Business Day immediately following the Conversion Date.

If the Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then the Reference Property into which the Notes shall be convertible shall be deemed to be the weighted average of the types and amounts of consideration actually received by the holder of Common Stock. The Company shall notify, in writing, the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the weighted average of the types and amounts of consideration received by the holders of Common Stock as soon as practicable after such determination is made and issue a press release containing the relevant information, which press release will be made available on our website.

Such supplemental indenture in connection with such Share Exchange Event shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 14. If the Reference Property in respect of any such Share Exchange Event includes shares of stock, other securities or other property or assets (including any combination thereof) of an entity other than the Company or the successor or purchasing corporation, as the case may be, in such Share Exchange Event, then such other entity, if it is a party to such Share Exchange Event, shall also execute such supplemental indenture, and such supplemental indenture shall contain such additional provisions to protect the interests of the Holders, including the right of Holders to require the Company to repurchase their Notes upon a Fundamental Change in accordance with Article 15, as the Board of Directors shall reasonably consider necessary by reason of the foregoing.

(b) In the event the Company shall execute a supplemental indenture pursuant to Section 14.07(a), the Company shall furnish to the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or other assets (including any combination thereof) that will comprise the Reference Property after any such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly send notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be sent to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) If the Notes become convertible into Reference Property, the Company shall notify the Trustee and issue a press release containing the relevant information, which press release will be made available on the Company’s website.

(d) The Company shall not become a party to any Share Exchange Event unless its terms are consistent with this Section 14.07. None of the foregoing provisions shall affect the right of a Holder to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Share Exchange Event.

(e) In connection with any adjustment to the Conversion Rate described in this Section 14.07, the Company shall also adjust the Initial Dividend Threshold based on the number of shares of Common Stock comprising the Reference Property and (if applicable) the value of any non-stock consideration comprising the Reference Property. If the Reference Property is composed solely of non-stock consideration, the Initial Dividend Threshold shall be zero.

(f) The above provisions of this Section shall similarly apply to successive Share Exchange Events.

Section 14.08. Certain Covenants.

(a) The Company covenants that all shares of Common Stock issued upon conversion of Notes shall be duly authorized, fully paid and non-assessable and free from all preemptive or similar rights of any securityholder of the Company and, except for any transfer taxes payable by the Company or a Holder, as the case may be, pursuant to Sections 14.02(d) and 14.02(e), free from all documentary, stamp or similar issue or transfer taxes, liens and charges as the result of any action by the Company.

(b) The Company covenants that if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company shall, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be.

(c) The Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system, the Company shall list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes.

Section 14.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to furnish to the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent (if other than the Trustee) the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent (if other than the Trustee) may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent (if other than the Trustee) immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). The parties hereto agree that all notices to the Trustee or the Conversion Agent under this Article 14 shall be in writing or as otherwise provided herein.

Section 14.10. Notice to Holders Prior to Certain Actions. In case of any:

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 14.04 or Section 14.11;

(b) Share Exchange Event or any consolidation, merger, sale, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article 11; or

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be furnished to the Trustee and the Conversion Agent (if other than the Trustee) and to be sent to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Share Exchange Event, any consolidation, merger, sale, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article 11 or any dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Share Exchange Event, consolidation, merger, sale, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article 11 or dissolution, liquidation or winding-up; provided, however, that if on such date, the Company does not have knowledge of such event or the adjusted Conversion Rate cannot be calculated, the Company shall deliver such notice as promptly as practicable upon obtaining knowledge of such event or information sufficient to make such calculation, as the case may be, and in no event later than the effective date of such adjustment. 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, any Share Exchange Event, any consolidation, merger, sale, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article 11 or dissolution, liquidation or winding-up.

Section 14.11. Stockholder Rights Plans. If the Company has a rights plan in effect upon conversion of the Notes into Common Stock, Holders that convert their Notes shall receive, in addition to any shares of Common Stock received in connection with such conversion, the appropriate number of rights under the rights plan, if any, and any certificate representing the share of Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such rights plan, as the same may be amended from time to time. However, if prior to any conversion, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable 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 shares of Common Stock, Distributed Property pursuant to Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Article 15
Purchase of Notes at Option of Holders

Section 15.01. Intentionally Omitted.

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior to the Maturity Date, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple of $1,000 in excess thereof, on the date (the “Fundamental Change Purchase Date”) specified by the Company that is not less than 20 nor more than 35 Business Days following the date of the Fundamental Change Company Notice (subject to extension to comply with applicable law) or if we fail to specify a Fundamental Change Purchase Date, the 35^th Business Day following the date of the Fundamental Change Company Notice (without prejudice to any rights or remedies the Holders may have on account of such failure), at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but not including, the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”), unless the Fundamental Change Purchase 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 Purchase Price shall be equal to 100% of the principal amount of Notes to be purchased pursuant to this Article 15.

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

(i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Purchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Certificated Notes, or in compliance with the Applicable 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 Purchase Date; and

(ii) delivery of the Notes, if the Notes are Certificated Notes, to the Paying Agent on or before the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the Applicable Procedures, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor.

The Fundamental Change Purchase Notice in respect of any Notes to be repurchased shall state:

A. in the case of Certificated Notes, the certificate numbers of the Notes to be delivered for repurchase;

B. the portion of the principal amount of Notes to be repurchased, which must be a minimum of $1,000 or an integral multiple of $1,000 in excess thereof; and

C. that the Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and this Indenture;

provided, however, that if the Notes are Global Notes, the Fundamental Change Purchase Notice must comply with the Applicable Procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03.

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

(c) On or before the 20th Business Day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (if other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the Fundamental Change and of the resulting purchase right at the option of the Holders arising as a result thereof. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) the effective date of the Fundamental Change;

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

(iv) the Fundamental Change Purchase Price;

(v) the Fundamental Change Purchase Date;

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

(vii) the Conversion Rate and any adjustments to the Conversion Rate;

(viii) that the Notes with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with the terms of this Indenture (or, in the case of a Global Note, complies with the Applicable Procedures with respect to such a withdrawal);

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

(x) the CUSIP, ISIN or other similar numbers, if any, assigned to the Notes, and the statement required in Section 2.09 hereto.

Simultaneously with providing such Fundamental Change Company Notice, the Company shall issue a press release containing such information (and make such press release available on the Company’s website).

At the Company’s written request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. In such a case, the Company shall deliver such notice to the Trustee at least three Business Days prior to the date that the notice is required to be given to the Holders (unless a shorter notice period shall be agreed to by the Trustee), together with Officer’s Certificate requesting that the Trustee give such notice.

Such notice shall be delivered to the Trustee, to the Paying Agent (if other than the Trustee) and to each Holder at its address shown in the Note Register (and to the beneficial owner as required by applicable law) or, in the case of Global Notes, in accordance with the Applicable Procedures.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02.

(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 Purchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Certificated Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the Applicable Procedures shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

Notwithstanding anything to the contrary in this Section 15.02, the Company shall not be required to repurchase, or to make an offer to repurchase, Notes upon a Fundamental Change if a third party makes the offer in the manner, at the times, and otherwise in compliance with the requirements set forth in this Indenture applicable to an offer by the Company to purchase Notes upon a Fundamental Change and such third party purchases all Notes validly tendered and not withdrawn upon such offer in the manner and otherwise in compliance with such requirements.

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

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

(b) if Certificated Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted, and

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

provided, however, that if the Notes are Global Notes, the withdrawal notice must comply with the Applicable Procedures.

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

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

(i) such Notes shall cease to be outstanding and interest shall cease to accrue on such Notes on such Fundamental Change Purchase Date or any applicable extension thereof (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

(ii) all other rights of the Holders of such Notes will terminate on the Fundamental Change Purchase Date (other than (x) the right to receive the Fundamental Change Purchase Price and (y) if the Fundamental Change Purchase Date falls after a Regular Record Date but on or prior to the related Interest Payment Date, the right of the Holder on such Regular Record Date to receive the accrued and unpaid interest to, but not including, the Fundamental Change Purchase Date).

(c) Upon surrender of a Note that is to be purchased in part pursuant to Section 15.02, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unpurchased portion of the Note surrendered, without payment of any service charge.

Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the Company will, if required:

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

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

(c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes;

in each case, so as to permit the rights and obligations under this Article 15 to be exercised in the time and in the manner specified in this Article 15. To the extent that any securities laws and regulations conflict with the provisions of this Indenture with respect to the repurchase of Notes, the Company shall be deemed not to be in breach of this Indenture as a result of compliance therewith.

Article 16

Section 16.01. Right of the Company to Redeem the Notes. The Notes shall not be redeemable by the Company prior to the Maturity Date, except as described in this Article 16, and no sinking fund is provided for the Notes.

(a) Subject to the terms of this Article 16, the Company has the right, at its election, to redeem all, or any portion, of the Notes (subject to the Notes that the Company is required to purchase pursuant to Section 15.02), for cash equal to the Redemption Price, at any time and from time to time, on a Redemption Date on or after November 5, 2023 and prior to August 1, 2026, if the Last Reported Sale Price per share of the Common Stock has been at least 130% of the Conversion Price then in effect for at least 20 Trading Days (whether or not consecutive), including the Trading Day immediately preceding the Redemption Notice Date, during any 30 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Redemption Notice Date.

(b) If the applicable Redemption Date falls after a Regular Record Date but on or prior to the immediately succeeding Interest Payment Date, the Company will pay, on or prior to such Interest Payment Date, the full amount of accrued and unpaid interest to the Holder as of the close of business of such Regular Record Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Redemption Date is before such Interest Payment Date) and the Redemption Price shall be equal to 100% of the principal amount of Notes to be redeemed.

A Redemption Date must be a Business Day of the Company’s choosing that is no more than 60, nor less than 30, calendar days after the Redemption Notice Date.

(b) A Notice of Redemption, if delivered in the manner provided herein, shall be conclusively presumed to have been given duly, whether or not the Holder receives such notice. In any case, failure to deliver such Notice of Redemption or any defect in the Notice of Redemption to the Holder of any Note designated for Redemption shall not affect the validity of the proceedings for the Redemption of any other Note.

(iii) the Redemption Price per $1,000 principal amount of Notes for such Redemption (and the amount, manner and timing of any interest payment payable pursuant to Section 16.01(b));

(vii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that, unless the Company defaults in the payment of the Redemption Price, the interest thereon, if any, shall cease to accrue on and after the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date that is prior to the Redemption Date to receive interest payable pursuant to Section 16.01(b));

(viii) that Holders may surrender their Notes called for Redemption for conversion at any time from the date of the Notice of Redemption to the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date or, if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides for the Redemption Price;

(ix) the procedures the Holder must follow to convert its Notes called for Redemption and, if the Company chooses to elect a Settlement Method for any such conversions, the relevant Settlement Method;

(xi) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes.

A Notice of Redemption shall be irrevocable. In the case of a Redemption, a Holder may submit for conversion any or all of its Notes called for Redemption at any time from the date of the Notice of Redemption to the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date or, if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides for the Redemption Price.

Section 16.03. Payment of Notes Called for Redemption.

(a) If any Notice of Redemption has been given in respect of the Notes in accordance with Section 16.02, the Notes shall become due and payable on the applicable Redemption Date at the place or places stated in the Notice of Redemption and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Notice of Redemption, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price.

(b) Prior to 11:00 a.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) an amount of cash sufficient to pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made on the Redemption Date for such Notes. The Trustee (or other Paying Agent appointed by the Company) shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price.

Section 16.04. Selection, Conversion and Transfer of Notes to be Redeemed in Part. If less than all Notes then outstanding are called for Redemption, then:

(a) the Trustee shall select the Notes to be redeemed in principal amounts of $1,000 or integral multiples of $1,000, from Notes then outstanding, by lot, pro rata to the extent practicable or by another method the Trustee routinely uses, and in each case to the extent permitted by the Depositary; and

(b) if only a portion of a Note is subject to Redemption and such Note is converted in part, then the converted portion of such Note will be deemed to be from the portion of such Note that was subject to the Redemption.

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and the principal amount thereof to be redeemed. If any Notes are to be redeemed in part only, the Company shall issue new Notes in principal amount equal to the unredeemed principal portion thereof.

In the event of any Redemption, the Company shall not be required to (x) issue, register the transfer or exchange of any Notes during the 15 calendar day period prior to the relevant Redemption Notice Date or (y) register the transfer or exchange of any Notes so selected for Redemption, in whole or in part, except the unredeemed portion of any Notes being redeemed in part.

Section 16.05. Restrictions on Redemption. The Company may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (or, if the Company fails to pay the Redemption Price, such later date on which the Company pays the Redemption Price) (except in the case of an acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes).

Section 16.06. Increased Conversion Rate Applicable to Certain Notes Called for Redemption Surrendered for Conversion in Connection with a Redemption.

(a) If a Holder elects to convert its Notes in connection with a Notice of Redemption pursuant to Section 14.01(b)(v) and this Article 16, the Conversion Rate will be increased by a number of Additional Shares as described in this Section 16.06. A conversion of Notes shall be deemed to be “in connection with” a Notice of Redemption if the relevant Conversion Date occurs during the period from the open of business on the Redemption Notice Date to the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date or, if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides for the Redemption Price.

(b) The number of Additional Shares, if any, by which the Conversion Rate shall be increased pursuant to this Section 16.06 if a Holder elects to convert its Notes in connection with a Notice of Redemption shall be determined by reference to the table set forth in Section 14.03(e) based on the Redemption Notice Date and the Redemption Reference Price, but determined for purposes of this Section 16.06 as if (i) the Holder had elected to convert its Notes in connection with a Make-Whole Fundamental Change, (ii) the Redemption Notice Date were the Effective Date of the relevant Make-Whole Fundamental Change and (iii) the Redemption Reference Price were the Stock Price in respect of such Make-Whole Fundamental Change.

These calculations include, but are not limited to, determinations of the Stock Price or Trading Price, the Last Reported Sale Prices of the Common Stock, the Redemption Price, the Redemption Reference Price, the Fundamental Change Purchase Price, the Conversion Price, the Daily VWAPs, the Daily Conversion Values, the Daily Settlement Amounts, accrued interest payable on the Notes (including any Additional Interest) and the Conversion Rate of the Notes. The Company shall make all these calculations in good faith and, absent manifest error, such calculations shall be final and binding on Holders of Notes, the Trustee and the Conversion Agent. The Company shall provide a schedule of its calculations to each of the Trustee and the Conversion Agent (if other than the Trustee), and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of such calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder of Notes upon the request of that Holder at the sole cost and expense of the Company. In no event shall the Trustee or the Conversion Agent be charged with knowledge of or have any duty to monitor Stock Price or Measurement Period. Neither the Trustee nor the Conversion Agent shall have any responsibility for calculations or determinations of amounts called for under the Notes or this Indenture, determining whether events requiring or permitting conversion have occurred, determining whether any adjustment is required to be made with respect to conversion rights and, if so, how much, or for the delivery of shares of Common Stock.

Section 17.17. U.S.A. Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as is required to satisfy the requirements of the U.S.A. Patriot Act.

Section 17.18. FATCA. In order to enable the Company and the Trustee to comply with its obligation with respect to this Indenture and the Notes under Section 1471 through 1474 of the Code and any Treasury regulations thereunder (“FATCA”) (inclusive of official interpretations of FATCA promulgated by competent authorities), any applicable agreement entered into pursuant to Section 1471(b) of the Code and/or any applicable intergovernmental agreement entered into in order to implement FATCA, each of the Company and the Trustee each agree (i) to provide to one another such reasonable information that is within its possession and is reasonably requested by the other to assist the other in determining whether it has tax related obligations under FATCA, and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments under this Indenture to the extent necessary to comply with FATCA. The terms of this section shall survive the termination of this Indenture to the extent permitted by law.

Section 17.19. Withholding Offset.

(a) The Company (through any withholding agent) shall be entitled to reduce or otherwise set-off against any payments made or deemed made in respect of the Notes or the Common Stock to the extent required by law. For the avoidance of doubt, if any withholding taxes (including backup withholding) are paid on behalf of a Holder of Notes, then those withholding taxes may be set- off against payments of cash or the delivery of shares of Common Stock, if any, in respect of the Notes (or, in some circumstances, any payments on the Common Stock) or sales proceeds received by, or other funds or assets of, that Holder of Notes. Any amounts withheld pursuant to this Section 17.19 shall be paid over by the Company (through a withholding agent) to the appropriate taxing authority.

(b) Prior to or upon the occurrence of any event that results in an actual or deemed payment by the Company to Holders in respect of the Notes or the Common Stock, the Company (through the Trustee, Paying Agent or any withholding agent) may request a Holder to furnish any appropriate documentation that may be required in order to determine the Company’s withholding obligations under applicable law (including, without limitation, an IRS Form W-9, Form W-8BEN, Form W-8BEN-E, or Form W-8ECI, as appropriate).

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed as of the date first written above.

Exhibit A-5

[FORM OF REVERSE OF NOTE]

UNITED STATES STEEL corporation
5.00% Senior Convertible Notes due 2026

This Note is one of a duly authorized issue of Notes of the Company, designated as its 5.00% Senior Convertible Notes due 2026 (the “Notes”), limited to the aggregate principal amount of $[ ] all issued under and pursuant to an Indenture, dated as of October 21, 2019 (the “Indenture”), between the Company and The Bank of New York Mellon, as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. The Notes represent the aggregate principal amount of outstanding Notes from time to time endorsed hereon and the aggregate principal amount of outstanding Notes represented hereby may from time to time be increased or reduced to reflect purchases, cancellations, conversions or transfers permitted by the Indenture.

In case an Event of Default relating to a bankruptcy (or similar proceeding) with respect to the Company shall have occurred, the principal of, and interest on, all Notes shall automatically become immediately due and payable, in the manner and with the effect set forth in the Indenture. In case any other Event 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 Redemption Price on a Redemption Date and the Fundamental Change Purchase Price or the Fundamental Change Purchase 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. Upon conversion of any Note, the Company shall, at its election, pay or deliver, as the case may be, cash, shares of Common Stock or a combination of cash and shares of Common Stock.

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.

Exhibit A-6

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Redemption Price and the Fundamental Change Purchase 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, herein prescribed.

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

The Notes are not subject to redemption through the operation of any sinking fund or otherwise. Under certain circumstances specified in the Indenture, the Notes will be subject to redemption by the Company at the Redemption Price.

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

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