THIS FIRST SUPPLEMENTAL INDENTURE, dated as of August 12, 2019 (the “Supplemental Indenture”), to the Indenture, dated as of August 12, 2019 (the “Base Indenture” and, as amended, modified and supplemented by this Supplemental Indenture, the “Indenture”), between Mesa Laboratories, Inc., a Colorado corporation, as issuer (the “Company”), and Wells Fargo Bank, National Association, as trustee (the “Trustee”).

WHEREAS, Sections 2.1, 2.2 and 9.1(h) of the Base Indenture authorize the Company to execute a supplemental indenture thereto to set forth the terms and other provisions of any new series of Securities;

WHEREAS, for its lawful corporate purposes, the Company has duly authorized the establishment of a new series of Securities to be titled the Company’s “1.375% Convertible Senior Notes due 2025” (the “Notes”), and has duly authorized the issuance of Notes initially in an aggregate principal amount not to exceed one hundred seventy two million five hundred thousand dollars ($172,500,000), subject to Section 2.02(B);

WHEREAS, in order to provide the terms and conditions of the Notes, the Company has duly authorized the execution and delivery of this Supplemental Indenture; and

WHEREAS, all acts and things necessary to make the Notes, when executed by the Company and authenticated and delivered by the Trustee or a duly authorized authenticating agent, as provided in the Indenture, the valid, binding and legal obligations of the Company, and the Indenture a valid agreement according to its terms, have been done and performed, and the execution of this Supplemental Indenture and the issuance under the Indenture of the Notes have in all respects been duly authorized.

NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE WITNESSETH, that in order to declare the terms and conditions upon which the Notes are, and are to be, authenticated, issued and delivered, and in consideration of the premises and of the purchase and acceptance of the Notes by the Holders, the Company covenants and agrees with the Trustee for the benefit of the other party and for the equal and proportionate benefit of the respective Holders from time to time (except as otherwise provided in the Indenture) as follows:

Article 1.   DEFINITIONS; RULES OF CONSTRUCTION

Except as otherwise expressly provided herein, capitalized terms used in this Supplemental Indenture and not otherwise defined in this Supplemental Indenture have the meanings assigned to them in the Base Indenture.  The terms defined in this Section 1.01 (except as otherwise expressly provided or unless the context otherwise requires) will apply for all purposes of the Indenture (and any further supplement thereto) as it relates to the Notes.  The terms defined in this Section 1.01 will be deemed, for purposes of the Notes, to supersede the definitions of the same terms in the Base Indenture, if applicable.

“Conversion Rate” initially means 3.5273 shares of Common Stock per $1,000 principal amount of Notes; provided, however, that the Conversion Rate is subject to adjustment pursuant to Article 5 ; provided, further, that whenever the Indenture refers to the Conversion Rate as of a particular date without setting forth a particular time on such date, such reference will be deemed

2

to be to the Conversion Rate immediately after the Close of Business on such date.

“Exchange Act” means the U.S. Securities Exchange Act of 1934, as amended.

“Fundamental Change” will be deemed to have occurred if, at any time after the Notes are originally issued and prior to the Maturity Date, any of the following occurs:

For the purposes of this definition, any transaction or event described in both clause (A) and in clause (B) above (without regard to the proviso in clause (B)) will be deemed to occur solely pursuant to clause (B) above (subject to such proviso).

For the avoidance of doubt, a merger or consolidation that is effected solely to change the Company’s jurisdiction and that satisfies either the proviso to clause (B) above or the proviso immediately following clause (D) above will not constitute a Fundamental Change.

“Issue Date” means August 12, 2019.

“Last Reported Sale Price” of the Common Stock for any Trading Day means the closing sale price per share (or, if no closing sale price is reported, the average of the last bid price and the last ask price per share or, if more than one in either case, the average of the average last bid prices and the average last ask prices per share) of Common Stock on such Trading Day as reported in composite transactions for the principal U.S. national or regional securities exchange on which the Common Stock is then listed.  If the Common Stock is not listed on a U.S. national or regional securities exchange on such Trading Day, then the Last Reported Sale Price will be the last quoted bid price per share of Common Stock on such Trading Day in the over-the-counter market as reported by OTC Markets Group Inc. or a similar organization.  If the Common Stock is not so quoted on such Trading Day, then the Last Reported Sale Price will be the average of the mid-point of the last bid price and the last ask price per share of Common Stock on such Trading Day from a nationally recognized independent investment banking firm selected by the Company, which may include any of the Underwriters.  Neither the Trustee nor the Conversion Agent will have any duty to determine the Last Reported Sale Price.

The changes, modifications and supplements to the Base Indenture effected by this Supplemental Indenture will be applicable only with respect to, and will only govern the terms of, the Notes, which may be issued from time to time, and will not apply to any other securities that may be issued under the Base Indenture unless a supplemental indenture with respect to such other securities specifically incorporates such changes, modifications and supplements.

The terms contained in the Notes constitute part of the Indenture, and, to the extent applicable, the Company and the Trustee, by their execution and delivery of the Indenture, agree to such terms and to be bound thereby; provided, however, that, to the extent that any provision of any Note conflicts with the provisions of the Indenture, the provisions of the Indenture will control for purposes of the Indenture and such Note.

(B)Additional Notes.  The Company may, subject to the provisions of the Indenture (including Section 2.3 of the Base Indenture), originally issue additional Notes with the same terms as the Initial Notes (except, to the extent applicable, with respect to the date as of which interest begins to accrue on such additional Notes and the first Interest Payment Date of such additional Notes), which additional Notes will, subject to the foregoing, be considered to be part of the same series of, and rank equally and ratably with all other Notes issued under the Indenture; provided, however, that if any such additional Notes are not fungible with other Notes issued under the Indenture for federal income tax or federal securities laws purposes, then such additional Notes will be identified by a separate CUSIP number or by no CUSIP number.

SECTION 2.03.METHOD OF PAYMENT.

(A)Global Notes.  The Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on the Maturity Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash Conversion Consideration for, any Global Note to the Depositary by wire transfer of immediately available funds no later than the time the same is due as provided in the Indenture.

(B)Physical Notes.  The Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on the Maturity Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash Conversion Consideration for, any Physical Note no later than the time the same is due as provided in the Indenture as follows: (i) if the principal amount of such Physical Note is at least five million dollars ($5,000,000) (or

13

such lower amount as the Company may choose in its sole and absolute discretion) and the Holder of such Physical Note entitled to such payment has delivered to the Paying Agent or the Trustee, no later than the time set forth in the immediately following sentence, a written request that the Company make such payment by wire transfer to an account of such Holder within the United States, by wire transfer of immediately available funds to such account; and (ii) in all other cases, by check mailed to the address of the Holder of such Physical Note entitled to such payment as set forth in the Register.  To be timely, such written request must be so delivered no later than the Close of Business on the following date: (x) with respect to the payment of any interest due on an Interest Payment Date, the immediately preceding Regular Record Date; (y) with respect to any cash Conversion Consideration, the relevant Conversion Date; and (z) with respect to any other payment, the date that is fifteen (15) calendar days immediately before the date such payment is due.

SECTION 2.04.ACCRUAL OF INTEREST; DEFAULTED AMOUNTS; WHEN PAYMENT DATE IS NOT A BUSINESS DAY.

(A)Accrual of Interest.  Each Note will accrue interest at a rate per annum equal to 1.375% (the “Stated Interest”), plus any Special Interest that may accrue pursuant to Section 7.03.  Stated Interest on each Note will (i) accrue from, and including, the most recent date to which Stated Interest has been paid or duly provided for (or, if no Stated Interest has theretofore been paid or duly provided for, the date set forth in the certificate representing such Note as the date from, and including, which Stated Interest will begin to accrue in such circumstance) to, but excluding, the date of payment of such Stated Interest; and (ii) be, subject to Sections 4.02(D) and 5.02(D) (but without duplication of any payment of interest), payable semi-annually in arrears on each Interest Payment Date, beginning on the first Interest Payment Date set forth in the certificate representing such Note, to the Holder of such Note as of the Close of Business on the immediately preceding Regular Record Date.  Stated Interest, and, if applicable, Special Interest, on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

(B)Defaulted Amounts.  If the Company fails to pay any amount (a “Defaulted Amount”) payable on a Note on or before the due date therefor as provided in the Indenture, then, regardless of whether such failure constitutes an Event of Default, (i) such Defaulted Amount will forthwith cease to be payable to the Holder of such Note otherwise entitled to such payment; (ii) to the extent lawful, interest (“Default Interest”) will accrue on such Defaulted Amount at a rate per annum equal to the rate per annum at which Stated Interest accrues from, and including, such due date to, but excluding, the date of payment of such Defaulted Amount and Default Interest; (iii) such Defaulted Amount and Default Interest will be paid on a payment date selected by the Company to the Holder of such Note as of the Close of Business on a special record date selected by the Company, provided that such special record date must be no more than fifteen (15), nor less than ten (10), calendar days before such payment date; and (iv) at least ten (10) calendar days before such special record date, the Company will send notice to the Trustee and the Holders that states such special record date, such payment date and the amount of such Defaulted Amount and Default Interest to be paid on such payment date.

(C)Delay of Payment when Payment Date is Not a Business Day.  If the due date for a payment on a Note as provided in the Indenture is not a Business Day, then, notwithstanding anything to the contrary in the Indenture or the Notes, such payment may be made on the

14

immediately following Business Day and no interest will accrue on such payment as a result of the related delay.  Solely for purposes of the immediately preceding sentence, a day on which the applicable place of payment is authorized or required by law or executive order to close or be closed will be deemed not to be a “Business Day.”

SECTION 2.05.REGISTRAR, PAYING AGENT AND CONVERSION AGENT.

This Section 2.05 will apply to the Notes in lieu of Section 2.4 of the Base Indenture, which will be deemed to be replaced with this Section 2.05, mutatis mutandis.

(A)Generally.  The Company will maintain (i) an office or agency in the continental United States where Notes may be presented for registration of transfer or for exchange (the “Registrar”); (ii) an office or agency in the continental United States where Notes may be presented for payment (the “Paying Agent”); and (iii) an office or agency in the continental United States where Notes may be presented for conversion (the “Conversion Agent”).  If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, then the Trustee will act as such.  For the avoidance of doubt, the Company or any of its Subsidiaries may act as Registrar, Paying Agent or Conversion Agent.

(B)Duties of the Registrar.  The Registrar will keep a record (the “Register”) of the names and addresses of the Holders, the Notes held by each Holder and the transfer, exchange, repurchase and conversion of Notes.  Absent manifest error, the entries in the Register will be conclusive and the Company and the Trustee may treat each Person whose name is recorded as a Holder in the Register as a Holder for all purposes.  The Register will be in written form or in any form capable of being converted into written form reasonably promptly.

(C)Co-Agents; Company’s Right to Appoint Successor Registrars, Paying Agents and Conversion Agents.  The Company may appoint one or more co-Registrars, co-Paying Agents and co-Conversion Agents, each of whom will be deemed to be a Registrar, Paying Agent or Conversion Agent, as applicable, under the Indenture.  Subject to Section 2.05(A), the Company may change any Registrar, Paying Agent or Conversion Agent (including appointing itself or any of its Subsidiaries to act in such capacity) without notice to any Holder.  The Company will notify the Trustee (and, upon request, any Holder) of the name and address of each Note Agent, if any, not a party to the Indenture and will enter into an appropriate agency agreement with each such Note Agent, which agreement will implement the provisions of the Indenture that relate to such Note Agent.

(D)Initial Appointments.  The Company appoints the Trustee as the initial Paying Agent, the initial Registrar and the initial Conversion Agent.

SECTION 2.06.PAYING AGENT AND CONVERSION AGENT TO HOLD PROPERTY IN TRUST.

This Section 2.06 will apply to the Notes in lieu of Section 2.5 of the Base Indenture, which will be deemed to be replaced with this Section 2.06, mutatis mutandis.

The Company will require each Paying Agent or Conversion Agent that is not the Trustee to agree in writing that such Note Agent will (A) hold in trust for the benefit of Holders or the

15

Trustee all money and other property held by such Note Agent for payment or delivery due on the Notes; and (B) notify the Trustee of any default by the Company in making any such payment or delivery.  The Company, at any time, may, and the Trustee, while any Default continues, may, require a Paying Agent or Conversion Agent to pay or deliver, as applicable, all money and other property held by it to the Trustee, after which payment or delivery, as applicable, such Note Agent (if not the Company or any of its Subsidiaries) will have no further liability for such money or property.  If the Company or any of its Subsidiaries acts as Paying Agent or Conversion Agent, then (A) it will segregate and hold in a separate trust fund for the benefit of the Holders or the Trustee all money and other property held by it as Paying Agent or Conversion Agent; and (B) references in the Indenture or the Notes to the Paying Agent or Conversion Agent holding cash or other property, or to the delivery of cash or other property to the Paying Agent or Conversion Agent, in each case for payment or delivery to any Holders or the Trustee or with respect to the Notes, will be deemed to refer to cash or other property so segregated and held separately, or to the segregation and separate holding of such cash or other property, respectively.  Upon the occurrence of any event in clause (ix) or (x) of Section 7.01(A) with respect to the Company (or with respect to any Subsidiary of the Company acting as Paying Agent or Conversion Agent), the Trustee will serve as the Paying Agent or Conversion Agent, as applicable, for the Notes.

SECTION 2.07.LEGENDS.

(A)Global Note Legend.  This Section 2.07(A) will apply to the Notes in lieu of Section 2.14.3 of the Base Indenture, which will be deemed to be replaced with this Section 2.07(A), mutatis mutandis.  Each Global Note will bear the Global Note Legend (or any similar legend, not inconsistent with the Indenture, required by the Depositary for such Global Note).

(B)Other Legends.  A Note may bear any other legend or text, not inconsistent with the Indenture, as may be required by applicable law or by any securities exchange or automated quotation system on which such Note is traded or quoted.

(C)Acknowledgement and Agreement by the Holders.  A Holder’s acceptance of any Note bearing any legend required by this Section 2.07 will constitute such Holder’s acknowledgement of, and agreement to comply with, the restrictions set forth in such legend.

SECTION 2.08.TRANSFERS AND EXCHANGES.

This Section 2.08 will apply to the Notes in lieu of Sections 2.7 and 2.14.2 of the Base Indenture, which will be deemed to be replaced with this Section 2.08, mutatis mutandis.

(A)Provisions Applicable to All Transfers and Exchanges.

(i)Subject to this Section 2.08, Physical Notes and beneficial interests in Global Notes may be transferred or exchanged from time to time and the Registrar will record each such transfer or exchange in the Register. The transfer and exchange of beneficial interest in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary in accordance with the Indentures and the procedures of the Depositary.

16

(ii)Each Note issued upon transfer or exchange of any other Note (such other Note being referred to as the “old Note” for purposes of this Section 2.08(A)(ii)) or portion thereof in accordance with the Indenture will be the valid obligation of the Company, evidencing the same indebtedness, and entitled to the same benefits under the Indenture, as such old Note or portion thereof, as applicable.

(iii)The Company, the Trustee and the Note Agents will not impose any service charge on any Holder for any transfer, exchange or conversion of Notes, but the Company, the Trustee, the Registrar and the Conversion Agent may require payment of a sum sufficient to cover any transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Notes, other than exchanges pursuant to Sections 2.09 and 8.05 of this Supplemental Indenture or Section 2.11 of the Base Indenture not involving any transfer.

(iv)Notwithstanding anything to the contrary in the Indenture or the Notes, a Note may not be transferred or exchanged in part unless the portion to be so transferred or exchanged is in an Authorized Denomination.

(v)The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with any transfer restrictions imposed by applicable law with respect to any Note or share of Common Stock issued upon conversion of any Note.

(vi)Each Note issued upon transfer of, or in exchange for, another Note will bear each legend, if any, required by Section 2.07.

(1)(x) the Depositary notifies the Company or the Trustee that the Depositary is unwilling or unable to continue as depositary for such Global Note or (y) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act and, in each case, the Company fails to appoint a successor Depositary within ninety (90) days of such notice or cessation;

(2)an Event of Default has occurred and is continuing and the Company, the Trustee or the Registrar has received a written request from the Depositary, or from a holder of a beneficial interest in such Global Note, to exchange such Global Note or beneficial interest, as applicable, for one or more Physical Notes; or

(3)the Company, in its sole discretion, permits the exchange of any

17

beneficial interest in such Global Note for one or more Physical Notes at the request of the owner of such beneficial interest.

(ii)Upon satisfaction of the requirements of the Indenture to effect a transfer or exchange of any Global Note (or any portion thereof):

(1)the Trustee will reflect any resulting decrease of the principal amount of such Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if such notation results in such Global Note having a principal amount of zero, the Company may (but is not required to) instruct the Trustee to cancel such Global Note pursuant to Section 2.12 of the Base Indenture);

(2)if required to effect such transfer or exchange, then the Trustee will reflect any resulting increase of the principal amount of any other Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such other Global Note;

(3)if required to effect such transfer or exchange, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.3 of the Base Indenture, a new Global Note bearing each legend, if any, required by Section 2.07; and

(4)if such Global Note (or such portion thereof), or any beneficial interest therein, is to be exchanged for one or more Physical Notes, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.3 of the Base Indenture, one or more Physical Notes that are in Authorized Denominations (not to exceed, in the aggregate, the principal amount of such Global Note to be so exchanged), are registered in such name(s) as the Depositary specifies (or as otherwise determined pursuant to customary procedures) and bear each legend, if any, required by Section 2.07.

(iii)Each transfer or exchange of a beneficial interest in any Global Note will be made in accordance with the Depositary Procedures.

(C)Transfers and Exchanges of Physical Notes.

(i)Subject to this Section 2.08, a Holder of a Physical Note may (x) transfer such Physical Note (or any portion thereof in an Authorized Denomination) to one or more other Person(s); (y) exchange such Physical Note (or any portion thereof in an Authorized Denomination) for one or more other Physical Notes in Authorized Denominations having an aggregate principal amount equal to the aggregate principal amount of the Physical Note (or portion thereof) to be so exchanged; and (z) if then permitted by the Depositary Procedures, transfer such Physical Note (or any portion thereof in an Authorized Denomination) in exchange for a beneficial interest in one or more Global Notes; provided, however, that, to effect any such transfer or exchange, such Holder must surrender such Physical Note to be transferred or exchanged to the office of the Registrar, together with any endorsements or transfer instruments reasonably required by the Company, the Trustee

18

or the Registrar.

(ii)Upon the satisfaction of the requirements of the Indenture to effect a transfer or exchange of any Physical Note (such Physical Note being referred to as the “old Physical Note” for purposes of this Section 2.08(C)(ii)) of a Holder (or any portion of such old Physical Note in an Authorized Denomination):

(1)such old Physical Note will be promptly cancelled pursuant to Section 2.12 of the Base Indenture;

(2)if such old Physical Note is to be transferred or exchanged only in part, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.3 of the Base Indenture, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such old Physical Note not to be transferred or exchanged; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by Section 2.07;

(3)in the case of a transfer:

(a)to the Depositary or a nominee thereof that will hold its interest in such old Physical Note (or such portion thereof) to be so transferred in the form of one or more Global Notes, the Trustee will reflect an increase of the principal amount of one or more existing Global Notes by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note(s), which increase(s) are in Authorized Denominations and aggregate to the principal amount to be so transferred, and which Global Note(s) bear each legend, if any, required by Section 2.07; provided, however, that if such transfer cannot be so effected by notation on one or more existing Global Notes (whether because no Global Notes bearing each legend, if any, required by Section 2.07 then exist, because any such increase will result in any Global Note having an aggregate principal amount exceeding the maximum aggregate principal amount permitted by the Depositary or otherwise), then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.3 of the Base Indenture, one or more Global Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so transferred; and (y) bear each legend, if any, required by Section 2.07; and

(b)to a transferee that will hold its interest in such old Physical Note (or such portion thereof) to be so transferred in the form of one or more Physical Notes, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.3 of the Base Indenture, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so transferred; (y) are registered in the name of such

19

transferee; and (z) bear each legend, if any, required by Section 2.07; and

(4)in the case of an exchange, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.3 of the Base Indenture, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so exchanged; (y) are registered in the name of the Person to whom such old Physical Note was registered; and (z) bear each legend, if any, required by Section 2.07.

(D)Transfers of Notes Subject to Repurchase or Conversion.  Notwithstanding anything to the contrary in the Indenture or the Notes, the Company, the Trustee and the Registrar will not be required to register the transfer of or exchange any Note that (i) has been surrendered for conversion, except to the extent that any portion of such Note is not subject to conversion; or (ii) is subject to a Fundamental Change Repurchase Notice validly delivered, and not withdrawn, pursuant to Section 4.02(F), except to the extent that any portion of such Note is not subject to such notice or the Company fails to pay the applicable Fundamental Change Repurchase Price when due.

SECTION 2.09.EXCHANGE AND CANCELLATION OF NOTES TO BE CONVERTED OR REPURCHASED.

(A)Partial Conversions and Repurchases of Physical Notes.  If only a portion of a Physical Note of a Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, then, as soon as reasonably practicable after such Physical Note is surrendered for such conversion or repurchase, the Company will cause such Physical Note to be exchanged, pursuant and subject to Section 2.08(C), for (i) one or more Physical Notes that are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased, as applicable, and deliver such Physical Note(s) to such Holder; and (ii) a Physical Note having a principal amount equal to the principal amount to be so converted or repurchased, as applicable, which Physical Note will be converted or repurchased, as applicable, pursuant to the terms of the Indenture; provided, however, that the Physical Note referred to in this clause (ii) need not be issued at any time after which such principal amount subject to such conversion or repurchase, as applicable, is deemed to cease to be outstanding pursuant to Section 2.12.

(B)Cancellation of Converted and Repurchased Notes.

(i)Physical Notes.  If a Physical Note (or any portion thereof that has not theretofore been exchanged pursuant to Section 2.09(A)) of a Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, then, promptly after the later of the time such Physical Note (or such portion) is deemed to cease to be outstanding pursuant to Section 2.12 and the time such Physical Note is surrendered for such conversion or repurchase, as applicable, (1) such Physical Note will be cancelled pursuant to Section 2.12 of the Base Indenture; and (2) in the case of a partial conversion or repurchase, the Company will issue, execute and deliver to such Holder, and the Trustee will authenticate, in each case in accordance with Section 2.3 of the Base

20

Indenture, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by Section 2.07.

(ii)Global Notes.  If a Global Note (or any portion thereof) is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, then, promptly after the time such Note (or such portion) is deemed to cease to be outstanding pursuant to Section 2.12 or repurchased by the Company pursuant to Section 2.13 and submitted to the Trustee for cancellation, the Trustee will reflect a decrease of the principal amount of such Global Note in an amount equal to the principal amount of such Global Note to be so converted or repurchased, as applicable, by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if the principal amount of such Global Note is zero following such notation, cancel such Global Note pursuant to Section 2.12 of the Base Indenture).

SECTION 2.10.REGISTERED HOLDERS; CERTAIN RIGHTS WITH RESPECT TO GLOBAL NOTES.

Only the Holder of a Note will have rights under the Indenture as the owner of such Note.  Without limiting the generality of the foregoing, Depositary Participants and owners of beneficial interests will have no rights as such under the Indenture with respect to any Global Note held on their behalf by the Depositary or its nominee, or by the Trustee as its custodian, and the Company, the Trustee and the Note Agents, and their respective agents, may treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever; provided, however, that (A) the Holder of any Global Note may grant proxies and otherwise authorize any Person, including Depositary Participants and Persons that hold interests in Notes through Depositary Participants, to take any action that such Holder is entitled to take with respect to such Global Note under the Indenture or the Notes; and (B) the Company and the Trustee, and their respective agents, may give effect to any written certification, proxy or other authorization furnished by the Depositary. None of the Company, the Trustee, the Registrar, the Paying Agent or the Conversion Agent or any agent of the Company or the Trustee will have any responsibility or liability for any act or omission by the Depositary, or 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.

SECTION 2.11.NOTES HELD BY THE COMPANY OR ITS AFFILIATES.

Without limiting the generality of Section 2.13, in determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any of its Affiliates will be deemed not to be outstanding; provided, however, that, for purposes of determining whether the Trustee is protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded.

SECTION 2.12.OUTSTANDING NOTES.

This Section 2.12 will apply to the Notes in lieu of Section 2.9 of the Base Indenture, which

21

will be deemed to be replaced with this Section 2.12, mutatis mutandis.

(A)Generally.  The Notes that are outstanding at any time will be deemed to be those Notes that, at such time, have been duly executed and authenticated, excluding those Notes (or portions thereof) that have theretofore been (i) cancelled by the Trustee or delivered to the Trustee for cancellation in accordance with Section 2.12 of the Base Indenture; (ii) assigned a principal amount of zero by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of any a Global Note representing such Note; (iii) paid in full in accordance with the Indenture; or (iv) deemed to cease to be outstanding to the extent provided in, and subject to, clause (B), (C) or (D) of this Section 2.12.

(B)Replaced Notes.  If a Note is replaced pursuant to Section 2.8 of the Base Indenture, then such Note will cease to be outstanding at the time of its replacement, unless the Trustee and the Company receive proof reasonably satisfactory to them that such Note is held by a “bona fide purchaser” under applicable law.

(C)Maturing Notes and Notes Subject to Repurchase.  If, on a Fundamental Change Repurchase Date or the Maturity Date, the Paying Agent holds money sufficient to pay the aggregate Fundamental Change Repurchase Price or principal amount, respectively, together, in each case, with the aggregate interest, in each case due on such date, then (unless there occurs a Default in the payment of any such amount) (i) the Notes (or portions thereof) to be repurchased, or that mature, on such date will be deemed, as of such date, to cease to be outstanding, except to the extent provided in Sections 4.02(D) or 5.02(D); and (ii) the rights of the Holders of such Notes (or such portions thereof), as such, will terminate with respect to such Notes (or such portions thereof), other than the right to receive the Fundamental Change Repurchase Price or principal amount, as applicable, of, and accrued and unpaid interest on, such Notes (or such portions thereof), in each case as provided in the Indenture.

(D)Notes to Be Converted.  At the Close of Business on the Conversion Date for any Note (or any portion thereof) to be converted, such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due, pursuant to Section 5.03(B) or Section 5.02(D), upon such conversion) be deemed to cease to be outstanding, except to the extent provided in Section 5.02(D) or Section 5.08.

(E)Cessation of Accrual of Interest.  Except as provided in Sections 4.02(D) or 5.02(D), interest will cease to accrue on each Note from, and including, the date that such Note is deemed, pursuant to this Section 2.12, to cease to be outstanding, unless there occurs a default in the payment or delivery of any cash or other property due on such Note.

SECTION 2.13.REPURCHASES BY THE COMPANY.

In addition, the Company may, directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other cash-settled derivatives, in each case without prior notice to the Holders. The Company will cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other cash-settled

22

derivatives) to be surrendered to the Trustee and the Trustee will follow the procedures described in Section 2.09(B)(ii). The Company will use commercially reasonable efforts to prevent any of its controlled Affiliates from acquiring any Note (or any beneficial interest therein); provided, however, that nothing in this Section 2.13 will prohibit the Company’s Subsidiaries from acquiring any Notes, provided such notes are promptly surrendered to the Trustee pursuant to this Section 2.13.

Article 3.   COVENANTS

This Article 3 will apply to the Notes in lieu of Article IV of the Base Indenture, which will be deemed to be replaced with this Article 3, mutatis mutandis.

SECTION 3.01.PAYMENT ON NOTES.

(B)Deposit of Funds.  Before 11:00 A.M., New York City time, on each Fundamental Change Repurchase Date or Interest Payment Date, and on the Maturity Date or any other date on which any cash amount is due on the Notes, the Company will deposit, or will cause there to be deposited, with the Paying Agent cash, in funds immediately available on such date, sufficient to pay the cash amount due on the applicable Notes on such date.  The Paying Agent will return to the Company, as soon as practicable, any money not required for such purpose.

SECTION 3.02.EXCHANGE ACT REPORTS.

(A)Generally.  The Company will send to the Trustee copies of all reports that the Company is required to file with the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act within fifteen (15) calendar days after the date that the Company is required to file the same (after giving effect to all applicable grace periods under the Exchange Act); provided, however, that the Company need not send to the Trustee any material for which the Company has received, or is seeking in good faith and has not been denied, confidential treatment by the SEC.  Reports, information and documents that the Company files with the SEC through the EDGAR system (or any successor thereto) will be deemed to be sent to the Trustee for the purposes of this Section 3.02(A) at the time such report is so filed via the EDGAR system (or such successor) for purposes of this Section 3.02(A).  Upon the request of any Holder, the Company will provide to such Holder a copy of any report that the Company has sent the Trustee pursuant to this Section 3.02(A), other than a report that is deemed to be sent to the Trustee pursuant to the preceding sentence.  The Company will also comply with its other obligations under Section 314(a)(1) of the Trust Indenture Act.

(B)Trustee’s Disclaimer.  The Trustee need not determine whether the Company has filed any material via the EDGAR system (or such successor).  The sending or filing of reports pursuant to Section 3.02(A) is for informational purposes only and the Trustee’s receipt of such reports shall not constitute constructive notice to the Trustee of any information contained, or determinable from information contained, therein, including the Company’s compliance with any

23

of its covenants under the Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with its covenants or with respect to any reports or other documents filed with the SEC or EDGAR or any website under the Indenture or participate in any conference calls.

SECTION 3.03.DEFAULT CERTIFICATES.

If a Default or Event of Default occurs, then the Company will, within thirty (30) days, deliver an Officer’s Certificate to the Trustee describing the same and what action the Company is taking or proposes to take with respect thereto; provided that the Company is not required to deliver such Officer’s Certificate if such Default or Event of Default, as applicable, has been cured within the applicable grace period, if any, provided in Section 7.01.

SECTION 3.04.CORPORATE EXISTENCE.

Subject to Article 6, the Company will cause to preserve and keep in full force and effect its corporate existence.

Article 4.   REPURCHASE

SECTION 4.01.NO SINKING FUND.

This Section 4.01 will apply to the Notes in lieu of Article XI of the Base Indenture, which will be deemed to be replaced with this Section 4.01, mutatis mutandis.

No sinking fund is required to be provided for the Notes.

SECTION 4.02.RIGHT OF HOLDERS TO REQUIRE THE COMPANY TO REPURCHASE NOTES UPON A FUNDAMENTAL CHANGE.

(A)Right of Holders to Require the Company to Repurchase Notes Upon a Fundamental Change.  Subject to the other terms of this Section 4.02, if a Fundamental Change occurs, then each Holder will have the right (the “Fundamental Change Repurchase Right”) to require the Company to repurchase such Holder’s Notes (or any portion thereof in an Authorized Denomination) on the Fundamental Change Repurchase Date for such Fundamental Change for a cash purchase price equal to the Fundamental Change Repurchase Price.

(B)Repurchase Prohibited in Certain Circumstances.  If the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or before the Fundamental Change Repurchase Date for a Repurchase Upon Fundamental Change (including as a result of the payment of the related Fundamental Change Repurchase Price, and any related

24

interest pursuant to the proviso to Section 4.02(D), on such Fundamental Change Repurchase Date), then (i) the Company may not repurchase any Notes pursuant to this Section 4.02; and (ii) the Company will cause any Notes theretofore surrendered for such Repurchase upon Fundamental Change to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Notes in accordance with the Depositary Procedures).

(C)Fundamental Change Repurchase Date.  The Fundamental Change Repurchase Date for any Fundamental Change will be a Business Day of the Company’s choosing that is no more than thirty five (35), nor less than twenty (20), Business Days after the date the Company sends the related Fundamental Change Notice pursuant to Section 4.02(E).

(D)Fundamental Change Repurchase Price.  The Fundamental Change Repurchase Price for any Note to be repurchased upon a Repurchase Upon Fundamental Change following a Fundamental Change is an amount in cash equal to the principal amount of such Note plus accrued and unpaid interest on such Note to, but excluding, the Fundamental Change Repurchase Date for such Fundamental Change; provided, however, that if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Repurchase Upon Fundamental Change, to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Fundamental Change Repurchase Date is before such Interest Payment Date); and (ii) the Fundamental Change Repurchase Price will not include accrued and unpaid interest on such Note to, but excluding, such Fundamental Change Repurchase Date.  For the avoidance of doubt, if an Interest Payment Date is not a Business Day within the meaning of Section 2.04(C) and such Fundamental Change Repurchase Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance with Section 2.04(C), on the next Business Day to Holders at of the Close of Business on the immediately preceding Regular Record Date; and (y) the Fundamental Change Repurchase Price will include interest on Notes to be repurchased from, and including, such Interest Payment Date.

(E)Fundamental Change Notice.  On or before the twentieth (20th) calendar day after the occurrence of a Fundamental Change, the Company will (x) send to each Holder, the Trustee and the Paying Agent a notice of such Fundamental Change (a “Fundamental Change Notice”) and (y) substantially contemporaneously therewith, issue a press release through such national newswire service as the Company then uses (or publish the same through such other widely disseminated public medium as the Company then uses, including its website) containing the information set forth in the Fundamental Change Notice.

Such Fundamental Change Notice must state:

(i)briefly, the events causing such Fundamental Change;

(ii)the effective date of such Fundamental Change;

25

(iii)the procedures that a Holder must follow to require the Company to repurchase its Notes pursuant to this Section 4.02, including the deadline for exercising the Fundamental Change Repurchase Right and the procedures for submitting and withdrawing a Fundamental Change Repurchase Notice;

(iv)the Fundamental Change Repurchase Date for such Fundamental Change;

(v)the Fundamental Change Repurchase Price per $1,000 principal amount of Notes for such Fundamental Change (and, if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso to Section 4.02(D));

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

(vii)the Conversion Rate in effect on the date of such Fundamental Change Notice and a description and quantification of any adjustments to the Conversion Rate that may result from such Fundamental Change (including pursuant to Section 5.07);

(viii)that Notes for which a Fundamental Change Repurchase Notice has been duly tendered and not duly withdrawn must be delivered to the Paying Agent for the Holder thereof to be entitled to receive the Fundamental Change Repurchase Price;

(ix)that Notes (or any portion thereof) that are subject to a Fundamental Change Repurchase Notice that has been duly tendered may be converted only if such Fundamental Change Repurchase Notice is withdrawn in accordance with the Indenture; and

(x)the CUSIP and ISIN numbers, if any, of the Notes.

Neither the failure to deliver a Fundamental Change Notice nor any defect in a Fundamental Change Notice will limit the Fundamental Change Repurchase Right of any Holder or otherwise affect the validity of any proceedings relating to any Repurchase Upon Fundamental Change.

(F)Procedures to Exercise the Fundamental Change Repurchase Right.

(i)Delivery of Fundamental Change Repurchase Notice and Notes to Be Repurchased.  To exercise its Fundamental Change Repurchase Right for a Note following a Fundamental Change, the Holder thereof must deliver to the Paying Agent:

(1)before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date (or such later time as may be required by law), a duly completed, written Fundamental Change Repurchase Notice with respect to such Note; and

(2)such Note, duly endorsed for transfer (if such Note is a Physical Note) or by book-entry transfer (if such Note is a Global Note).

26

The Paying Agent will promptly deliver to the Company a copy of each Fundamental Change Repurchase Notice that it receives.

(ii)Contents of Fundamental Change Repurchase Notices.  Each Fundamental Change Repurchase Notice with respect to a Note must state:

(1)if such Note is a Physical Note, the certificate number of such Note;

(2)the principal amount of such Note to be repurchased, which must be an Authorized Denomination; and

(3)that such Holder is exercising its Fundamental Change Repurchase Right with respect to such principal amount of such Note;

provided, however, that if such Note is a Global Note, then such Fundamental Change Repurchase Notice must comply with the Depositary Procedures (and any such Fundamental Change Repurchase Notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)).

(iii)Withdrawal of Fundamental Change Repurchase Notice.  A Holder that has delivered a Fundamental Change Repurchase Notice with respect to a Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent at any time before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date.  Such withdrawal notice must state:

(1)if such Note is a Physical Note, the certificate number of such Note;

(2)the principal amount of such Note to be withdrawn, which must be an Authorized Denomination; and

(3)the principal amount of such Note, if any, that remains subject to such Fundamental Change Repurchase Notice, which must be an Authorized Denomination;

provided, however, that if such Note is a Global Note, then such withdrawal notice must comply with the Depositary Procedures (and any such withdrawal notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)).

Upon receipt of any such withdrawal notice with respect to a Note (or any portion thereof), the Paying Agent will (x) promptly deliver a copy of such withdrawal notice to the Company; and (y) if such Note is surrendered to the Paying Agent, cause such Note (or such portion thereof in accordance with Section 2.09, treating such Note as having been then surrendered for partial repurchase in the amount set forth in such withdrawal notice as remaining subject to repurchase) to be returned to the Holder thereof (or, if applicable with respect to any Global Note, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Note

27

in accordance with the Depositary Procedures).

(G)Payment of the Fundamental Change Repurchase Price.  Without limiting the Company’s obligation to deposit the Fundamental Change Repurchase Price within the time proscribed by Section 3.01(B), the Company will cause the Fundamental Change Repurchase Price for a Note (or portion thereof) to be repurchased pursuant to a Repurchase Upon Fundamental Change to be paid to the Holder thereof on or before the later of (i) the applicable Fundamental Change Repurchase Date; and (ii) the date (x) such Note is delivered to the Paying Agent (in the case of a Physical Note) or (y) the Depositary Procedures relating to the repurchase, and the delivery to the Paying Agent, of such Holder’s beneficial interest in such Note to be repurchased are complied with (in the case of a Global Note).  For the avoidance of doubt, interest payable pursuant to the proviso to Section 4.02(D) on any Note to be repurchased pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to such proviso regardless of whether such Note is delivered or such Depositary Procedures are complied with pursuant to the first sentence of this Section 4.02(G).

(H)Third Party May Conduct Repurchase Offer In Lieu of the Company.  Notwithstanding anything to the contrary in this Section 4.02, the Company will be deemed to satisfy its obligations under this Section 4.02 if (i) one or more third parties conduct any Repurchase Upon Fundamental Change and related offer to repurchase Notes otherwise required by this Section 4.02 in a manner that would have satisfied the requirements of this Section 4.02 if conducted directly by the Company; and (ii) an owner of a beneficial interest in any Note repurchased by such third party or parties will not receive a lesser amount (as a result of taxes, additional expenses or for any other reason) than such owner would have received had the Company repurchased such Note.

(I)Compliance with Applicable Securities Laws.  To the extent applicable, the Company will comply, in all material respects, with all federal and state securities laws in connection with a Repurchase Upon Fundamental Change (including complying with Rules 13e-4 and 14e-1 under the Exchange Act and filing any required Schedule TO, to the extent applicable) so as to permit effecting such Repurchase Upon Fundamental Change in the manner set forth in the Indenture; provided, however, that, to the extent that the Company’s obligations pursuant to this Section 4.02 conflict with any law or regulation that is applicable to the Company and enacted after the Issue Date, the Company’s compliance with such law or regulation will not be considered to be a Default of such obligations.

(J)Repurchase in Part.  Subject to the terms of this Section 4.02, Notes may be repurchased pursuant to a Repurchase Upon Fundamental Change in part, but only in Authorized Denominations.  Provisions of this Section 4.02 applying to the repurchase of a Note in whole will equally apply to the repurchase of a permitted portion of a Note.

SECTION 4.03.NO RIGHT OF REDEMPTION BY THE COMPANY.

This Section 4.03 will apply to the Notes in lieu of Article III of the Base Indenture, which will be deemed to be replaced with this Section 4.03, mutatis mutandis.

The Company does not have the right to redeem the Notes.

28

Article 5.   CONVERSION

SECTION 5.01.RIGHT TO CONVERT.

(A)Generally.  Subject to the provisions of this Article 5, each Holder may, at its option, convert such Holder’s Notes into Conversion Consideration.

(B)Conversions in Part.  Subject to the terms of the Indenture, Notes may be converted in part, but only in Authorized Denominations.  Provisions of this Article 5 applying to the conversion of a Note in whole will equally apply to conversions of a permitted portion of a Note.

(C)When Notes May Be Converted.

(i)Generally.  Subject to Section 5.01(C)(ii), a Note may be converted only in the following circumstances:

(1)Conversion upon Satisfaction of Common Stock Sale Price Condition.  A Holder may convert its Notes 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 per share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price for each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter.

(2)Conversion upon Satisfaction of Note Trading Price Condition.  A Holder may convert its Notes during the five (5) consecutive Business Days immediately after any ten (10) consecutive Trading Day period (such ten (10) consecutive Trading Day period, the “Measurement Period”) if the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder in accordance with the procedures set forth below, for each Trading Day of the Measurement Period was less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day.  The condition set forth in the preceding sentence is referred to in the Indenture as the “Trading Price Condition.”

The Trading Price will be determined by the Bid Solicitation Agent pursuant to this Section 5.01(C)(i)(2) and the definition of “Trading Price.”  The Bid Solicitation Agent (if not the Company) will have no obligation to determine the Trading Price of the Notes unless the Company has requested such determination in writing, and the Company will have no obligation to make such request (or seek bids itself) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock and the Conversion Rate.  If a Holder provides such evidence, then the Company will (if acting as Bid Solicitation Agent), or will instruct the Bid Solicitation Agent to, determine the Trading Price of the Notes beginning on the next Trading Day and

29

on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day.  If the Trading Price Condition has been met as set forth above, then the Company will notify the Holders, the Trustee and the Conversion Agent of the same.  If, on any Trading Day after the Trading Price Condition has been met as set forth above, the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day, then the Company will notify the Holders, the Trustee and the Conversion Agent of the same.

(3)Conversion upon Specified Corporate Events.

(a)Certain Distributions.  If, prior to the Close of Business on the Business Day immediately preceding April 15, 2025, the Company elects to:

(I)distribute, to all or substantially all holders of Common Stock, any rights, options or warrants (other than rights issued pursuant to a stockholder rights plan, so long as such rights have not separated from the Common Stock and are not exercisable until the occurrence of a triggering event, except that such rights will be deemed to be distributed under this clause (I) upon their separation from the Common Stock or upon the occurrence of such triggering event) entitling them, for a period of not more than forty-five (45) calendar days after the record 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 per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced (determined in the manner set forth in the third paragraph of Section 5.05(A)(ii)); or

(II)distribute, to all or substantially all holders of Common Stock, assets or securities of the Company or rights to purchase the Company’s securities, which distribution per share of Common Stock has a value, as reasonably determined by the Board of Directors, exceeding ten percent (10%) of the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before the date such distribution is announced,

then, in either case, (x) the Company will send notice of such distribution, and of the related right to convert Notes, to Holders, the Trustee and the Conversion Agent at least twenty-five (25) Scheduled Trading Days before the Ex-Dividend Date for such distribution (or, if later in the case of any such separation of rights issued pursuant to a stockholder rights plan or the

30

occurrence of any such triggering event under a stockholder rights plan, as soon as reasonably practicable after the Company becomes aware that such separation or triggering event has occurred or will occur); and (y) once the Company has sent such notice, Holders may convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately before such Ex-Dividend Date and the Company’s announcement that such distribution will not take place.

(b)Certain Corporate Events.  If a Fundamental Change, Make-Whole Fundamental Change or Common Stock Change Event occurs prior to the Close of Business on the Business Day immediately preceding April 15, 2025 (other than a merger or other business combination transaction that is effected solely to change the Company’s jurisdiction of incorporation and that does not constitute a Fundamental Change or a Make-Whole Fundamental Change), then, in each case, Holders may convert their Notes at any time from, and including, the effective date of such transaction or event to, and including, the thirty fifth (35th) Trading Day after such effective date (or, if such transaction or event also constitutes a Fundamental Change, to, but excluding, the related Fundamental Change Repurchase Date); provided, however, that if the Company does not provide the notice referred to in the immediately following sentence by such effective date, then the last day on which the Notes are convertible pursuant to this sentence will be extended by the number of Business Days from, and including, such effective date to, but excluding, the date the Company provides such notice.  No later than such effective date, the Company will send notice to the Holders, the Trustee and the Conversion Agent of such transaction or event, such effective date and the related right to convert Notes.

(4)Conversions During Free Convertibility Period.  A Holder may convert its Notes at any time from, and including, April 15, 2025 until the Close of Business on the second (2nd) Scheduled Trading Day immediately before the Maturity Date.

For the avoidance of doubt, the Notes may become convertible pursuant to any one or more of the preceding sub-paragraphs of this Section 5.01(C)(i) and the Notes ceasing to be convertible pursuant to a particular sub-paragraph of this Section 5.01(C)(i) will not preclude the Notes from being convertible pursuant to any other sub-paragraph of this Section 5.01(C)(i).

(ii)Limitations and Closed Periods.  Notwithstanding anything to the contrary in the Indenture or the Notes:

(1)Notes may be surrendered for conversion only after the Open of Business and before the Close of Business on a day that is a Business Day;

(2)in no event may any Note be converted after the Close of Business

31

on the Scheduled Trading Day immediately before the Maturity Date; and

(3)if a Fundamental Change Repurchase Notice is validly delivered pursuant to Section 4.02(F) with respect to any Note, then such Note may not be converted, except to the extent (a) such Note is not subject to such notice; (b) such notice is withdrawn in accordance with Section 4.02(F); or (c) the Company fails to pay the Fundamental Change Repurchase Price for such Note in accordance with the Indenture.

SECTION 5.02.CONVERSION PROCEDURES.

(A)Generally.

(i)Global Notes.  To convert a beneficial interest in a Global Note that is convertible pursuant to Section 5.01(C), the owner of such beneficial interest must (1) comply with the Depositary Procedures for converting such beneficial interest (at which time such conversion will become irrevocable); and (2) pay any amounts due pursuant to Section 5.02(D) or Section 5.02(E).

(ii)Physical Notes.  To convert all or a portion of a Physical Note that is convertible pursuant to Section 5.01(C), the Holder of such Note must (1) complete, manually sign and deliver to the Conversion Agent the conversion notice attached to such Physical Note or a facsimile of such conversion notice; (2) deliver such Physical Note to the Conversion Agent (at which time such conversion will become irrevocable); (3) furnish any endorsements and transfer documents that the Company or the Conversion Agent may require; and (4) pay any amounts due pursuant to Section 5.02(D) or Section 5.02(E).

(B)Effect of Converting a Note.  At the Close of Business on the Conversion Date for a Note (or any portion thereof), such Note (or such portion thereof) will be deemed to cease to be outstanding (and, for the avoidance of doubt, no Person will be deemed to be a Holder of such Note (or such portion thereof) as of the Close of Business on such Conversion Date), except to the extent provided in Section 5.02(D).

(C)Holder of Record of Conversion Shares.  The Person in whose name any share of Common Stock is issuable upon conversion of any Note will be deemed to become the holder of record of such share as of the Close of Business on (i) the Conversion Date for such conversion, in the case of Physical Settlement; or (ii) the last VWAP Trading Day of the Observation Period for such conversion, in the case of Combination Settlement.

(D)Interest Payable upon Conversion in Certain Circumstances.  If the Conversion Date of a Note is after a Regular Record Date and before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such conversion (and, for the avoidance of doubt, notwithstanding anything set forth in the proviso to this sentence), to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date); and (ii) the Holder surrendering such Note for conversion must deliver to the Conversion Agent, at the time of such surrender, an amount of cash

32

equal to the amount of such interest referred to in clause (i) above; provided, however, that the Holder surrendering such Note for conversion need not deliver such cash (w) if such Conversion Date occurs after the Regular Record Date immediately before the Maturity Date; (x) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment Date; or (y) to the extent of any overdue interest or interest that has accrued on any overdue interest.  For the avoidance of doubt, as a result of, and without limiting the generality of, the foregoing, if a Note is converted with a Conversion Date that is after the Regular Record Date immediately before the Maturity Date, then the Company will pay, as provided above, the interest that would have accrued on such Note to, but excluding, the Maturity Date.  For the avoidance of doubt, if the Conversion Date of a Note to be converted is on an Interest Payment Date, then the Holder of such Note at the Close of Business on the Regular Record Date immediately before such Interest Payment Date will be entitled to receive, on such Interest Payment Date, the unpaid interest that has accrued on such Note to, but excluding, such Interest Payment Date, and such Note, when surrendered for conversion, need not be accompanied by any cash amount pursuant to the first sentence of this Section 5.02(D).

(E)Taxes and Duties.  If a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or transfer tax or duty due on the issue or delivery of any shares of Common Stock upon such conversion; provided, however, that if any tax or duty is due because such Holder requested such shares to be registered in a name other than such Holder’s name, then such Holder will pay such tax or duty and, until having received a sum sufficient to pay such tax or duty, the Conversion Agent may refuse to deliver any such shares to be issued in a name other than that of such Holder.

(F)Conversion Agent to Notify Company of Conversions.  If any Note is submitted for conversion to the Conversion Agent or the Conversion Agent receives any notice of conversion with respect to a Note, then the Conversion Agent will promptly notify the Company and the Trustee of such occurrence, together with any other information reasonably requested by the Company.

SECTION 5.03.SETTLEMENT UPON CONVERSION.

(A)Settlement Method.  Upon the conversion of any Note, the Company will settle such conversion by paying or delivering, as applicable and as provided in this Article 5, either (x) shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 5.03(B)(i)(1) (a “Physical Settlement”); (y) solely cash as provided in Section 5.03(B)(i)(2) (a “Cash Settlement”); or (z) a combination of cash and shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 5.03(B)(i)(3) (a “Combination Settlement”).

The Company will have the right to elect the Settlement Method applicable to any conversion of a Note; provided, however, that:

(i)all conversions of Notes with a Conversion Date that occurs on or after April 15, 2025 will be settled using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders and the Conversion Agent no later than the

33

Open of Business on April 15, 2025;

(ii)if the Company elects a Settlement Method with respect to the conversion of any Note whose Conversion Date occurs before April 15, 2025, then the Company will send notice of such Settlement Method to the Holder of such Note and the Conversion Agent no later than the Close of Business on the Business Day immediately after such Conversion Date;

(iii)the Company will use the same Settlement Method for all conversions of Notes with a Conversion Date that occurs on the same day (and, for the avoidance of doubt, the Company will not be obligated to use the same Settlement Method with respect to conversions of Notes whose Conversion Dates occur on different days, except as provided in clause (i));

(iv)if the Company does not timely elect a Settlement Method with respect to the conversion of a Note, then the Company will be deemed to have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not constitute a Default or Event of Default);

(v)if the Company timely elects Combination Settlement with respect to the conversion of a Note but does not timely notify the Holder of such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of Notes (and, for the avoidance of doubt, the failure to timely send such notification will not constitute a Default or Event of Default); and

(vi)the Settlement Method will be subject to Section 5.09(A)(2).

In addition, the Company will have the right, exercisable at its election by sending notice of such exercise to the Holders (with a copy to the Trustee and the Conversion Agent), to irrevocably fix the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the date such notice is sent to Holders, provided that such Settlement Method must be a Settlement Method that the Company is then permitted to elect (for the avoidance of doubt, including pursuant to, and subject to, the other provisions of this Section 5.03(A)).  Such notice, if sent, must set forth the applicable Settlement Method and expressly state that the election is irrevocable and applicable to all conversions of Notes with a Conversion Date that occurs on or after the date such notice is sent to Holders.  For the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend the Indenture or the Notes, including pursuant to Section 8.01(G) (it being understood, however, that the Company may nonetheless choose to execute such an amendment at its option).

(B)Conversion Consideration.

(i)Generally.  Subject to Section 5.03(B)(ii) and Section 5.03(B)(iii), the type and amount of consideration (the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be converted will be as follows:

(1)if Physical Settlement applies to such conversion, a number of

34

shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion;

(2)if Cash Settlement applies to such conversion, cash in an amount equal to the sum of the Daily Conversion Values for each VWAP Trading Day in the Observation Period for such conversion; or

(3)if Combination Settlement applies to such conversion, consideration consisting of (a) a number of shares of Common Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such conversion; and (b) an amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation Period.

(ii)Cash in Lieu of Fractional Shares.  If Physical Settlement or Combination Settlement applies to the conversion of any Note and the number of shares of Common Stock deliverable pursuant to Section 5.03(B)(i) upon such conversion is not a whole number, then such number will be rounded down to the nearest whole number and the Company will deliver, in addition to the other consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such fraction and (2) (x) the Daily VWAP on the Conversion Date for such conversion (or, if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day), in the case of Physical Settlement; or (y) the Daily VWAP on the last VWAP Trading Day of the Observation Period for such conversion, in the case of Combination Settlement.

(iii)Conversion of Multiple Notes by a Single Holder.  If a Holder converts more than one (1) Note on a single Conversion Date, then the Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and practicable under, the Depositary Procedures) be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder.

(iv)Notice of Calculation of Conversion Consideration.  If Cash Settlement or Combination Settlement applies to the conversion of any Note, then the Company will determine the Conversion Consideration due thereupon promptly following the last VWAP Trading Day of the applicable Observation Period and will promptly thereafter send notice to the Trustee and the Conversion Agent of the same and the calculation thereof in reasonable detail.  Neither the Trustee nor the Conversion Agent will have any duty to make any such determination.

(C)Delivery of the Conversion Consideration.  Except as set forth in Sections 5.05(A), 5.05(D) and 5.09, the Company will pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder as follows: (i) if Cash Settlement or Combination Settlement applies to such conversion, on or before the second (2nd) Business Day immediately after the last VWAP Trading Day of the Observation Period for such conversion; and (ii) if Physical Settlement applies to such conversion, on or before the second (2nd) Business Day immediately after the Conversion Date for such conversion; provided, however, that if Physical Settlement applies to the conversion of any Note with a Conversion Date that is after the Regular

35

Record Date immediately before the Maturity Date, then, solely for purposes of such conversion, (x) the Company will pay or deliver, as applicable, the Conversion Consideration due upon such conversion no later than the Maturity Date (or, if the Maturity Date is not a Business Day, the next Business Day); and (y) the Conversion Date will instead be deemed to be the second (2nd) Business Day immediately before the Maturity Date.

(D)Deemed Payment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion.  If a Holder converts a Note, then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and, except as provided in Section 5.02(D), the Company’s delivery of the Conversion Consideration due in respect of such conversion will be deemed to fully satisfy and discharge the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding the Conversion Date.  As a result, except as provided in Section 5.02(D), any accrued and unpaid interest on a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited.  In addition, subject to Section 5.02(D), if the Conversion Consideration for a Note consists of both cash and shares of the Common Stock, then accrued and unpaid interest that is deemed to be paid therewith will be deemed to be paid first out of such cash.

SECTION 5.04.RESERVE AND STATUS OF COMMON STOCK ISSUED UPON CONVERSION.

(A)Stock Reserve.  At all times when any Notes are outstanding, the Company will reserve, out of its authorized but unissued and unreserved shares of Common Stock, a number of shares of Common Stock sufficient to permit the conversion of all then-outstanding Notes, assuming (x) Physical Settlement will apply to such conversion; and (y) the Conversion Rate is increased by the maximum amount pursuant to which the Conversion Rate may be increased pursuant to Section 5.07.

(B)Status of Conversion Shares; Listing.  Each Conversion Share, if any, delivered upon conversion of any Note will be a newly issued or treasury share (except that any Conversion Share delivered by a designated financial institution pursuant to Section 5.08 need not be a newly issued or treasury share) and will be duly and validly issued, fully paid, non-assessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder of such Note or the Person to whom such Conversion Share will be delivered).  If the Common Stock is then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will cause each Conversion Share, when delivered upon conversion of any Note, to be admitted for listing on such exchange or quotation on such system.

SECTION 5.05.ADJUSTMENTS TO THE CONVERSION RATE.

(A)Events Requiring an Adjustment to the Conversion Rate.  The Conversion Rate will be adjusted from time to time as follows:

(i)Stock Dividends, Splits and Combinations.  If the Company issues solely 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 stock split or a stock combination of the Common Stock (in each case excluding an issuance solely pursuant to a Common Stock

36

Change Event, as to which Section 5.09 will apply), then the Conversion Rate will be adjusted based on the following formula:

where:

CR0=the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately before the Open of Business on the effective date of such stock split or stock combination, as applicable;

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

OS0=the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date or effective date, as applicable, without giving effect to such dividend, distribution, stock split or stock combination; and

OS1=the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock combination.

If any dividend, distribution, stock split or stock combination of the type described in this Section 5.05(A)(i) is declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been declared or announced.

(ii)Rights, Options and Warrants.  If the Company distributes, to all or substantially all holders of Common Stock, rights, options or warrants (other than rights issued or otherwise distributed pursuant to a stockholder rights plan, as to which the provisions set forth in Sections 5.05(A)(iii)(1) and 5.05(F) will apply) entitling such holders, for a period of not more than forty-five (45) calendar days after the record 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 per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion Rate will be increased based on the following formula:

37

where:

CR0=the Conversion Rate in effect immediately before 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;

OS=the number of shares of Common Stock outstanding immediately before 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=a number of shares of Common Stock obtained by dividing (x) the aggregate price payable to exercise such rights, options or warrants by (y) the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced.

To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including as a result of such rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, option or warrants.  To the extent such rights, options or warrants are not so distributed, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the Ex-Dividend Date for the distribution of such rights, options or warrants not occurred.

For purposes of this Section 5.05(A)(ii) and Section 5.01(C)(i)(3)(a)(I), in determining whether any rights, options or warrants entitle holders of Common Stock 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 per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date the distribution of such rights, options or warrants is announced, and in determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if not cash, to be determined by the Board of Directors.

(iii)Spin-Offs and Other Distributed Property.

(1)Distributions Other than Spin-Offs.  If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common

38

Stock, excluding:

(v)dividends, distributions, rights, options or warrants for which an adjustment to the Conversion Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(i) or 5.05(A)(ii);

(w)dividends or distributions paid exclusively in cash for which an adjustment to the Conversion Rate is required (or would be required assuming the Dividend Threshold were zero and without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iv);

(x)rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent provided in Section 5.05(F);

(y)Spin-Offs for which an adjustment to the Conversion Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iii)(2); and

(z)a distribution solely pursuant to a Common Stock Change Event, as to which Section 5.09 will apply,

then the Conversion Rate will be increased based on the following formula:

where:

CR0=the Conversion Rate in effect immediately before 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;

SP=the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before such Ex-Dividend Date; and

FMV=the fair market value (as determined by the Board of Directors), as of such Ex-Dividend Date, of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed per share of Common Stock pursuant to such distribution;

provided, however, that if FMV is equal to or greater than SP, then, in lieu of the

39

foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at the same time and on the same terms as holders of Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

To the extent such distribution is not so paid or made, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the distribution, if any, actually made or paid.

(2)Spin-Offs.  If the Company distributes or dividends shares of Capital Stock of any class or series, or similar equity interest, of or relating to an Affiliate, a Subsidiary or other business unit of the Company to all or substantially all holders of the Common Stock (other than solely pursuant to a Common Stock Change Event, as to which Section 5.09 will apply), and such Capital Stock or equity interest is listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), then the Conversion Rate will be increased based on the following formula:

where:

CR0=the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such Spin-Off;

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

FMV=the product of (x) the average of the Last Reported Sale Prices per share or unit of the Capital Stock or equity interests distributed in such Spin-Off over the ten (10) consecutive Trading Day period (the “Spin-Off Valuation Period”) beginning on, and including, such Ex-Dividend Date (such average to be determined as if references to Common Stock in the definitions of Last Reported Sale Price, Trading Day and Market Disruption Event were instead references to such Capital Stock or equity interests); and (y) the number of shares or units of such Capital Stock or equity interests distributed per share of Common Stock in such Spin-Off; and

SP=the average of the Last Reported Sale Prices per share of Common Stock for each Trading Day in the Spin-Off Valuation Period.

40

The adjustment to the Conversion Rate pursuant to this Section 5.05(A)(iii)(2) will be calculated as of the Close of Business on the last Trading Day of the Spin-Off Valuation Period but will be given effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off, with retroactive effect.  If a Note is converted and the Conversion Date (in the case of Physical Settlement) or any VWAP Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the Spin-Off Valuation Period, then, notwithstanding anything to the contrary in the Indenture or the Notes, the Company will, if necessary, delay the settlement of such conversion until the second (2nd) Business Day after the last day of the Spin-Off Valuation Period.

To the extent any dividend or distribution of the type set forth in this Section 5.05(A)(iii)(2) is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid.

(iv)Cash Dividends or Distributions.  If any cash dividend or distribution is made to all or substantially all holders of Common Stock (other than a regular quarterly cash dividend that does not exceed the Dividend Threshold per share of Common Stock), then the Conversion Rate will be increased based on the following formula:

where:

CR0=the Conversion Rate in effect immediately before 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 such Ex-Dividend Date;

SP=the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before such Ex-Dividend Date;

T=an amount (subject to the proviso below, the “Dividend Threshold”) initially equal to $0.16 per share of Common Stock; provided, however, that (x) if such dividend or distribution is not a regular quarterly cash dividend on the Common Stock, then the Dividend Threshold will be deemed to be zero dollars ($0.00) per share of Common Stock with respect to such dividend or distribution; and (y) the Dividend Threshold will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Price is adjusted as a result of the operation of Section 5.05(A) (other than this Section 5.05(A)(iv)); and

41

D=the cash amount distributed per share of Common Stock in such dividend or distribution;

provided, however, that if D is equal to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution, at the same time and on the same terms as holders of Common Stock, the amount of cash that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

To the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid.

(v)Tender Offers or Exchange Offers.  If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock (other than solely pursuant to an odd-lot tender offer pursuant to Rule 13e-4(h)(5) under the Exchange Act), and the value (determined as of the Expiration Time by the Board of Directors) of the cash and other consideration paid per share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale Price per share of Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased based on the following formula:

where:

CR0=the Conversion Rate in effect immediately before the time (the “Expiration Time”) such tender or exchange offer expires;

CR1=the Conversion Rate in effect immediately after the Expiration Time;

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

OS0=the number of shares of Common Stock outstanding immediately before the Expiration Time (including all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

42

OS1=the number of shares of Common Stock outstanding immediately after the Expiration Time (excluding all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and

SP=the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive Trading Day period (the “Tender/Exchange Offer Valuation Period”) beginning on, and including, the Trading Day immediately after the Expiration Date;

provided, however, that the Conversion Rate will in no event be adjusted down pursuant to this Section 5.05(A)(v), except to the extent provided in the immediately following paragraph.  The adjustment to the Conversion Rate pursuant to this Section 5.05(A)(v) will be calculated as of the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period but will be given effect immediately after the Expiration Time, with retroactive effect.  If a Note is converted and the Conversion Date (in the case of Physical Settlement) or any VWAP Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs on the Expiration Date or during the Tender/Exchange Offer Valuation Period, then, notwithstanding anything to the contrary in the Indenture or the Notes, the Company will, if necessary, delay the settlement of such conversion until the second (2nd) Business Day after the last day of the Tender/Exchange Offer Valuation Period.

To the extent such tender or exchange offer is announced but not consummated (including as a result of the Company being precluded from consummating such tender or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer are rescinded, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender or exchange offer.

(B)No Adjustments in Certain Cases.

(i)Where Holders Participate in the Transaction or Event Without Conversion.  Notwithstanding anything to the contrary in Section 5.05(A), the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring an adjustment pursuant to Section 5.05(A) (other than a stock split or combination of the type set forth in Section 5.05(A)(i) or a tender or exchange offer of the type set forth in Section 5.05(A)(v)) if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder of Notes, in such transaction or event without having to convert such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the related record date; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such date.

(ii)Certain Events.  The Company will not be required to adjust the Conversion Rate except as provided in Section 5.04 or Section 5.07.  Without limiting the foregoing,

43

the Company will not be obligated to adjust the Conversion Rate on account of:

(1)stock repurchases, including structured or derivative transactions, pursuant to a stock repurchase program approved by the Board of Directors, in each case that are not tender or exchange offers of the type set forth in Section 5.05(A)(v);

(2)except as otherwise provided in Section 5.04, the sale of shares of Common Stock for a purchase price that is less than the market price per share of Common Stock or less than the Conversion Price;

(3)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 such plan;

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

(5)the issuance of any shares of Common Stock pursuant to any option, warrant, right or convertible or exchangeable security of the Company outstanding as of the Issue Date;

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

(7)accrued and unpaid interest on the Notes.

(C)               ��               Adjustment Deferral.  If an adjustment to the Conversion Rate otherwise required by this Article 5 would result in a change of less than one percent (1%) to the Conversion Rate, then, notwithstanding anything to the contrary in this Article 5, the Company may, at its election, defer such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest of the following: (i) when all such deferred adjustments would result in a change of at least one percent (1%) to the Conversion Rate; (ii) the Conversion Date of, or any VWAP Trading Day of an Observation Period for, any Note; (iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs; and (iv) April 15, 2025.

(D)Adjustments Not Yet Effective.  Notwithstanding anything to the contrary in the Indenture or the Notes, if:

(i)a Note is to be converted pursuant to Physical Settlement or Combination Settlement;

(ii)the record date, effective date or Expiration Time for any event that requires an adjustment to the Conversion Rate pursuant to Section 5.05(A) has occurred on or before the Conversion Date for such conversion (in the case of Physical Settlement) or on or before any VWAP Trading Day in the Observation Period for such conversion (in the

44

case of Combination Settlement), but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date or VWAP Trading Day, as applicable;

(iii)the Conversion Consideration due upon such conversion (in the case of Physical Settlement) or due in respect of such VWAP Trading Day (in the case of Combination Settlement) includes any whole shares of Common Stock; and

(iv)such shares are not entitled to participate in such event (because they were not held on the related record date or otherwise),

then, solely for purposes of such conversion, the Company will, without duplication, give effect to such adjustment on such Conversion Date (in the case of Physical Settlement) or such VWAP Trading Day (in the case of Combination Settlement).  In such case, if the date on which the Company is otherwise required to deliver the consideration due upon such conversion is before the first date on which the amount of such adjustment can be determined, then the Company will delay the settlement of such conversion until the second (2nd) Business Day after such first date.

(E)Conversion Rate Adjustments where Converting Holders Participate in the Relevant Transaction or Event.  Notwithstanding anything to the contrary in the Indenture or the Notes, if:

(i)a Conversion Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to Section 5.05(A);

(ii)a Note is to be converted pursuant to Physical Settlement or Combination Settlement;

(iii)the Conversion Date for such conversion (in the case of Physical Settlement) or any VWAP Trading Day in the Observation Period for such conversion (in the case of Combination Settlement) occurs on or after such Ex-Dividend Date and on or before the related record date;

(iv)the Conversion Consideration due upon such conversion (in the case of Physical Settlement) or due with respect to such VWAP Trading Day (in the case of Combination Settlement) includes any whole shares of Common Stock based on a Conversion Rate that is adjusted for such dividend or distribution; and

(v)such shares would be entitled to participate in such dividend or distribution (including pursuant to Section 5.02(C)),

then (x) in the case of Physical Settlement, such Conversion Rate adjustment will not be given effect for such conversion and the shares of Common Stock issuable upon such conversion based on such unadjusted Conversion Rate will not be entitled to participate in such dividend or distribution, but there will be added, to the Conversion Consideration otherwise due upon such conversion, the same kind and amount of consideration that would have been delivered in such dividend or distribution with respect to such shares of Common Stock had such shares been entitled to participate in such dividend or distribution; and (y) in the case of Combination Settlement, the

45

Conversion Rate adjustment relating to such Ex-Dividend Date will be made for such conversion in respect of such VWAP Trading Day, but the shares of Common Stock issuable with respect to such VWAP Trading Day based on such adjusted Conversion Rate will not be entitled to participate in such dividend or distribution.

(F)Stockholder Rights Plans.  If any shares of Common Stock are to be issued upon conversion of any Note and, at the time of such conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under the Indenture upon such conversion, the rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such time, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section 5.05(A)(iii)(1) on account of such separation as if, at the time of such separation, the Company had made a distribution of the type referred to in such Section to all holders of the Common Stock, subject to readjustment in accordance with such Section if such rights expire, terminate or are redeemed.

(G)Limitation on Effecting Transactions Resulting in Certain Adjustments.  The Company will not engage in or be a party to any transaction or event that would require the Conversion Rate to be adjusted pursuant to Section 5.05(A) or Section 5.07 to an amount that would result in the Conversion Price per share of Common Stock being less than the par value per share of Common Stock.

(H)Equitable Adjustments to Prices.  Whenever any provision of the Indenture requires the Company to calculate the average of the Last Reported Sale Prices, or any function thereof, over a period of multiple days (including to calculate the Stock Price or an adjustment to the Conversion Rate), or to calculate Daily VWAPs over an Observation Period, the Company will make proportionate adjustments, if any, to such calculations to account for any adjustment to the Conversion Rate pursuant to Section 5.05(A)(i) that becomes effective, or any event requiring such an adjustment to the Conversion Rate where the Ex-Dividend Date or effective date, as applicable, of such event occurs, at any time during such period or Observation Period, as applicable.

(I)Calculation of Number of Outstanding Shares of Common Stock.  For purposes of Section 5.05(A), the number of shares of Common Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock; and (ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company pays any dividend or makes any distribution on shares of Common Stock held in its treasury).

(J)Calculations.  All calculations with respect to the Conversion Rate and adjustments thereto will be made to the nearest 1/10,000th of a share of Common Stock (with 5/100,000ths rounded upward).

(K)Notice of Conversion Rate Adjustments.  Upon the effectiveness of any adjustment to the Conversion Rate pursuant to Section 5.05(A), the Company will promptly send notice to the Holders, the Trustee and the Conversion Agent containing (i) a brief description of the transaction or other event on account of which such adjustment was made; (ii) the Conversion Rate

46

in effect immediately after such adjustment; and (iii) the effective time of such adjustment.  Whenever the Conversion Rate is adjusted as herein provided, the Company will promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee has received such Officer’s Certificate, the Trustee will 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.

SECTION 5.06.VOLUNTARY ADJUSTMENTS.

(A)Generally.  To the extent permitted by law and applicable stock exchange rules, the Company, from time to time, may (but is not required to) increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is either (x) in the best interest of the Company; or (y) advisable to avoid or diminish any income tax imposed on holders of Common Stock or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common Stock or any similar event; (ii) such increase is in effect for a period of at least twenty (20) Business Days; and (iii) such increase is irrevocable during such period.

(B)Notice of Voluntary Increases.  If the Board of Directors determines to increase the Conversion Rate pursuant to Section 5.06(A), then, no later than the first Business Day of the related twenty (20) Business Day period referred to Section 5.06(A), the Company will send notice to each Holder of such increase, the amount thereof and the period during which such increase will be in effect.

SECTION 5.07.ADJUSTMENTS TO THE CONVERSION RATE IN CONNECTION WITH A MAKE-WHOLE FUNDAMENTAL CHANGE.

(A)Generally.  If a Make-Whole Fundamental Change occurs and the Conversion Date for the conversion of a Note occurs during the related Make-Whole Fundamental Change Conversion Period, then, subject to this Section 5.07, the Conversion Rate applicable to such conversion will be increased by a number of shares (the “Additional Shares”) set forth in the table below corresponding (after interpolation as provided in, and subject to, the provisions below) to the effective date and the Stock Price of such Make-Whole Fundamental Change:

	Stock Price
Effective Date	$210.00	$250.00	$283.50	$325.00	$375.00	$425.00	$500.00	$600.00	$700.00	$800.00	$950.00	$1,200.00
August 12, 2019	1.2346	0.9499	0.7270	0.5349	0.3799	0.2755	0.1751	0.0979	0.0541	0.0282	0.0084	0.0000

If such effective date or Stock Price is not set forth in the table above, then:

(i)if such Stock Price is between two Stock Prices in the table above or the effective date is between two dates in the table above, then the number of Additional Shares will be determined by a straight-line interpolation between the numbers of Additional

47

Shares set forth for the higher and lower Stock Prices in the table above or the earlier and later dates in the table above, based on a 365- or 366-day year, as applicable; and

(ii)if the Stock Price is greater than $1,200.00 (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above are adjusted pursuant to Section 5.07(B)), or less than $210.00 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the Conversion Rate.

Notwithstanding anything to the contrary in the Indenture or the Notes, in no event will the Conversion Rate be increased to an amount that exceeds 4.7619 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is required to be adjusted pursuant to Section 5.05(A).

(B)Adjustment of Stock Prices and Additional Shares.  The Stock Prices in the first row (i.e., the column headers) of the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Price is adjusted as a result of the operation of Section 5.05(A).  The numbers of Additional Shares in the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Rate is adjusted pursuant to Section 5.07(A).

(C)Notice of the Occurrence of a Make-Whole Fundamental Change.  The Company will notify the Holders, the Trustee and the Conversion Agent of each Make-Whole Fundamental Change in accordance with Section 5.01(C)(i)(3)(b) (or, if the effective date of such Make-Whole Fundamental Change is on or after April 15, 2025, no later than such effective date).

(D)Settlement of Cash Make-Whole Fundamental Changes.  For the avoidance of doubt, if holders of Common Stock receive solely cash in a Make-Whole Fundamental Change, then, pursuant to Section 5.09, conversions of Notes will thereafter be settled no later than the second (2nd) Business Day after the relevant Conversion Date.

SECTION 5.08.EXCHANGE IN LIEU OF CONVERSION.

Notwithstanding anything to the contrary in this Article 5, and subject to the terms of this Section 5.08, if a Note is submitted for conversion, the Company may elect to arrange to have such Note exchanged in lieu of conversion by a financial institution designated by the Company.  To make such election, the Company must send notice of such election to the Holder of such Note, the Trustee and the Conversion Agent before the Close of Business on the Business Day immediately following the Conversion Date for such Note.  If the Company has made such election, then:

(A)no later than the Business Day immediately following such Conversion Date, the Company must deliver (or cause the Conversion Agent to deliver) such Note, together with delivery instructions for the Conversion Consideration due upon such conversion (including wire instructions, if applicable), to a financial institution designated by the Company that has agreed to deliver such Conversion Consideration in the manner and at the time the Company would have had to deliver the same pursuant to this Article 5;

48

(B)if such Note is a Global Note, then (i) such designated institution will send written confirmation to the Conversion Agent promptly after wiring the cash Conversion Consideration, if any, and delivering any other Conversion Consideration, due upon such conversion to the Holder of such Note; and (ii) the Conversion Agent will as soon as reasonably practicable thereafter contact such Holder’s custodian with the Depositary to confirm receipt of the same; and

(C)such Note will not cease to be outstanding by reason of such exchange in lieu of conversion; provided, however, so long as the Notes are Global Notes, the Company will comply with Depositary Procedures; and

provided, however, that if such financial institution does not accept such Note or fails to timely deliver such Conversion Consideration, then the Company will be responsible for delivering such Conversion Consideration in the manner and at the time provided in this Article 5 as if the Company had not elected to make an exchange in lieu of conversion.  The Trustee and each Note Agent will have no responsibility for any act or omission of any financial institution designated by the Company pursuant to this Section 5.08.

SECTION 5.09.EFFECT OF COMMON STOCK CHANGE EVENT.

(A)Generally.  If there occurs any:

(i)recapitalization, reclassification or change of the Common Stock (other than (x) changes solely resulting from a subdivision or combination of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value or (z) stock splits and stock combinations that do not involve the issuance of any other series or class of securities);

(ii)consolidation, merger, combination or statutory share exchange involving the Company; or

(iii)sale, lease or other transfer of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any Person,

and, as a result of which, the Common Stock is converted into, or is exchanged for, or represents solely the right to receive, other securities, cash or other property, or any combination of the foregoing (such an event, a “Common Stock Change Event,” and such other securities, cash or property, the “Reference Property,” and the amount and kind of Reference Property that a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect to any arrangement not to issue or deliver a fractional portion of any security or other property), a “Reference Property Unit”), then, notwithstanding anything to the contrary in the Indenture or the Notes,

(1)from and after the effective time of such Common Stock Change Event, (I) the Conversion Consideration due upon conversion of any Note, and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 5 (or in any related definitions) were instead a reference to the same number of Reference Property Units; and (II) for purposes of the

49

definition of “Fundamental Change” and “Make-Whole Fundamental Change,” the terms “Common Stock” and “common equity” will be deemed to mean the common equity, if any, forming part of such Reference Property;

(2)if such Reference Property Unit consists entirely of cash, then the Company will be deemed to elect Physical Settlement in respect of all conversions whose Conversion Date occurs on or after the effective date of such Common Stock Change Event and will pay the cash due upon such conversions no later than the fifth (5th) Business Day after the relevant Conversion Date; and

(3)for these purposes, (I) the Daily VWAP of any Reference Property Unit or portion thereof that consists of a class of common equity securities will be determined by reference to the definition of “Daily VWAP,” substituting, if applicable, the Bloomberg page for such class of securities in such definition; and (II) the Daily VWAP of any Reference Property Unit or portion thereof that does not consist of a class of common equity securities, and the Last Reported Sale Price of any Reference Property Unit or portion thereof that does not consist of a class of securities, will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof).

If the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of stockholder election, then the composition of the Reference Property Unit will be deemed to be the weighted average of the types and amounts of consideration actually received, per share of Common Stock, by the holders of Common Stock.  The Company will notify Holders of such weighted average as soon as practicable after such determination is made.

At or before the effective time of such Common Stock Change Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a supplemental indenture pursuant to Section 8.01(F), which supplemental indenture will (x) provide for subsequent conversions of Notes in the manner set forth in this Section 5.09; (y) provide for subsequent adjustments to the Conversion Rate pursuant to Section 5.07(A) in a manner consistent with this Section 5.09 (including giving effect, in the reasonable discretion of the Company, to the Dividend Threshold in a manner that preserves the economic interests of the Holders); and (z) contain such other provisions as the Company reasonably determines are appropriate to preserve the economic interests of the Holders and to give effect to the provisions of this Section 5.09(A).  If the Reference Property includes shares of stock or other securities or assets of a Person other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain such additional provisions the Company reasonably determines are appropriate to preserve the economic interests of the Holders.

(B)Notice of Common Stock Change Events.  The Company will provide notice of each Common Stock Change Event to Holders, the Trustee and the Conversion Agent no later than the effective date of such Common Stock Change Event.

(C)Compliance Covenant.  The Company will not become a party to any Common

50

Stock Change Event unless its terms are consistent with this Section 5.09.

SECTION 5.10.RESPONSIBILITY OF TRUSTEE.

The Trustee and each Note Agent will not at any time be under any duty or responsibility to the Company, any Holder, or any other Person to determine any Settlement Amount, to calculate the Trading Price, the Sale Price, 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 determine whether the Notes are convertible, 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 Note Agent will not be accountable with respect to the validity, sufficiency, 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 Note Agent will be responsible for any act or omission of the Company, or any failure of the Company or its agent 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 5. Without limiting the generality of the foregoing, neither the Trustee nor any Note Agent will be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 8.01 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 8.01 or to any adjustment to be made with respect thereto, but may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and will be protected in conclusively relying upon, the Officer’s Certificate (which the Company will be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor any Note Agent will be responsible for determining whether any event has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in this Article 5 with respect to the commencement or termination of such conversion rights, on which notices the Trustee and any Note Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and each Note Agent promptly after the occurrence of any such event or at such other times as will be provided for in this Supplemental Indenture.

Article 6.   SUCCESSORS

This Article 6 will apply to the Notes in lieu of Article V of the Base Indenture, which will be deemed to be replaced with this Article 6, mutatis mutandis.

SECTION 6.01.WHEN THE COMPANY MAY MERGE, ETC.

(A)Generally.  The Company will not consolidate with or merge with or into, or (directly, or indirectly through one or more of its Subsidiaries) sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and

51

its Subsidiaries, taken as a whole, to another Person (a “Business Combination Event”), unless:

(i)the resulting, surviving or transferee Person either (x) is the Company or (y) if not the Company, is a corporation (the “Successor Corporation”) duly organized and existing under the laws of the United States of America, any State thereof or the District of Columbia that expressly assumes (by executing and delivering to the Trustee, at or before the effective time of such Business Combination Event, a supplemental indenture pursuant to Section 8.01(E)) all of the Company’s obligations under the Indenture and the Notes; and

(ii)immediately after giving effect to such Business Combination Event, no Default or Event of Default will have occurred and be continuing.

(B)Delivery of Officer’s Certificate and Opinion of Counsel to the Trustee.  Before the effective time of any Business Combination Event, the Company will deliver to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that (i) such Business Combination Event (and, if applicable, the related supplemental indenture) complies with Section 6.01(A); and (ii) all conditions precedent to such Business Combination Event provided in the Indenture have been satisfied.

SECTION 6.02.SUCCESSOR CORPORATION SUBSTITUTED.

At the effective time of any Business Combination Event that complies with Section 6.01, the Successor Corporation (if not the Company) will succeed to, and may exercise every right and power of, the Company under the Indenture and the Notes with the same effect as if such Successor Corporation had been named as the Company in the Indenture and the Notes, and, except in the case of a lease of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, the predecessor Company will be discharged from its obligations under the Indenture and the Notes.

Article 7.   DEFAULTS AND REMEDIES

This Article 7 will apply to the Notes in lieu of Article VI of the Base Indenture, which will be deemed to be replaced with this Article 7, mutatis mutandis.

SECTION 7.01.EVENTS OF DEFAULT.

(A)Definition of Events of Default.  “Event of Default” means the occurrence of any of the following:

(i)a default in the payment when due (whether at maturity, upon Repurchase Upon Fundamental Change or otherwise) of the principal of, or the Fundamental Change Repurchase Price for, any Note;

(ii)a default for thirty (30) days in the payment when due of interest on any Note;

(iii)the Company’s failure to deliver, when required by the Indenture, a

52

Fundamental Change Notice, or a notice pursuant to Section 5.01(C)(i)(3), if (in the case of any notice other than a notice pursuant to Section 5.01(C)(i)(3)(a)) such failure is not cured within three (3) Business Days after its occurrence;

(iv)a default in the Company’s obligation to convert a Note in accordance with Article 5 upon the exercise of the conversion right with respect thereto, if such default is not cured within three (3) Business Days after its occurrence;

(v)a default in the Company’s obligations under Article 6;

(vi)a default in any of the Company’s obligations or agreements under the Indenture or the Notes (other than a default set forth in clause (i), (ii), (iii), (iv) or (v) of this Section 7.01(A)) where such default is not cured or waived within sixty (60) days after notice to the Company by the Trustee, or to the Company and the Trustee by Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, which notice must specify such default, demand that it be remedied and state that such notice is a “Notice of Default”;

(vii)a default by the Company or any of its Significant Subsidiaries with respect to any one or more mortgages, agreements or other instruments under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed of at least twenty-five million dollars ($25,000,000) (or its foreign currency equivalent) in the aggregate of the Company or any of its Significant Subsidiaries, whether such indebtedness exists as of the Issue Date or is thereafter created, where such default:

(1)constitutes a failure to pay the principal of such indebtedness when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, in each case after the expiration of any applicable grace period; or

(2)results in such indebtedness becoming or being declared due and payable before its stated maturity,

in each case where such default is not cured or waived within thirty (30) days after notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding;

(viii)one or more final judgments being rendered against the Company or any of its Significant Subsidiaries for the payment of at least twenty-five million dollars ($25,000,000) (or its foreign currency equivalent) in the aggregate (excluding any amounts covered by insurance), where such judgment is not discharged or stayed within sixty (60) days after (i) the date on which the right to appeal the same has expired, if no such appeal has commenced; or (ii) the date on which all rights to appeal have been extinguished;

(ix)the Company or any of its Significant Subsidiaries, pursuant to or within the meaning of any Bankruptcy Law, either:

(1)commences a voluntary case or proceeding;

53

(2)consents to the entry of an order for relief against it in an involuntary case or proceeding;

(3)consents to the appointment of a custodian of it or for any substantial part of its property;

(4)makes a general assignment for the benefit of its creditors;

(5)takes any comparable action under any foreign Bankruptcy Law; or

(6)generally is not paying its debts as they become due; or

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

(1)is for relief against Company or any of its Significant Subsidiaries in an involuntary case or proceeding;

(2)appoints a custodian of the Company or any of its Significant Subsidiaries, or for any substantial part of the property of the Company or any of its Significant Subsidiaries;

(3)orders the winding up or liquidation of the Company or any of its Significant Subsidiaries; or

(4)grants any similar relief under any foreign Bankruptcy Law,

and, in each case under this Section 7.01(A)(x), such order or decree remains unstayed and in effect for at least sixty (60) days.

(B)Cause Irrelevant.  Each of the events set forth in Section 7.01(A) will constitute an Event of Default regardless of the cause thereof or whether voluntary or involuntary or 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.

SECTION 7.02.ACCELERATION.

(A)Automatic Acceleration in Certain Circumstances.  If an Event of Default set forth in Section 7.01(A)(ix) or 7.01(A)(x) occurs with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company), then the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any Person.

(B)Optional Acceleration.  Subject to Section 7.03, if an Event of Default (other than an Event of Default set forth in Section 7.01(A)(ix) or 7.01(A)(x) with respect to the Company and not solely with respect to a Significant Subsidiary of the Company) occurs and is continuing, then the Trustee, by notice to the Company, or Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee,

54

may declare the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding to become due and payable immediately.

(C)Rescission of Acceleration.  Notwithstanding anything to the contrary in the Indenture or the Notes, the Holders of a majority in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, on behalf of all Holders, rescind any acceleration of the Notes and its consequences if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (ii) all existing Events of Default (except the non-payment of principal of, or interest on, the Notes that has become due solely because of such acceleration) have been cured or waived, and all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel have been paid.  No such rescission will affect any subsequent Default or impair any right consequent thereto.

SECTION 7.03.SOLE REMEDY FOR A FAILURE TO REPORT.

(A)Generally.  Notwithstanding anything to the contrary in the Indenture or the Notes, the Company may elect that the sole remedy for any Event of Default (a “Reporting Event of Default”) pursuant to Section 7.01(A)(vi) arising from the Company’s failure to comply with Section 3.02 will, for each of the first one hundred eighty (180) calendar days on which a Reporting Event of Default has occurred and is continuing, consist exclusively of the accrual of Special Interest on the Notes.  If the Company has made such an election, then (i) the Notes will be subject to acceleration pursuant to Section 7.02 on account of the relevant Reporting Event of Default from, and including, the one hundred eighty-first (181st) calendar day on which a Reporting Event of Default has occurred and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when due; and (ii) Special Interest will cease to accrue on any Notes from, and including, such one hundred eighty-first (181st) calendar day (it being understood that interest on any defaulted Special Interest will nonetheless accrue pursuant to Section 2.04(B)).

(B)Amount and Payment of Special Interest.  Any Special Interest that accrues on a Note pursuant to Section 7.03(A) will be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate per annum equal to one quarter of one percent (0.25%) of the principal amount thereof for the first ninety (90) days on which Special Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof.  For the avoidance of doubt, any Special Interest that accrues on a Note will be in addition to the Stated Interest that accrues on such Note.

(C)Notice of Election.  To make the election set forth in Section 7.03(A), the Company must send to the Holders, the Trustee and the Paying Agent, before the date on which each Reporting Event of Default first occurs, a notice that (i) briefly describes the report(s) that the Company failed to file with the SEC; (ii) states that the Company is electing that the sole remedy for such Reporting Event of Default consist of the accrual of Special Interest; and (iii) briefly describes the periods during which and rate at which Special Interest will accrue and the circumstances under which the Notes will be subject to acceleration on account of such Reporting Event of Default.

(D)Notice to Trustee and Paying Agent; Trustee’s Disclaimer.  If Special Interest

accrues on any Note, then, no later than five (5) Business Days before each date on which such Special Interest is to be paid, the Company will deliver notice, which may be in the form of an Officer’s Certificate, to the Trustee and the Paying Agent stating (i) that the Company is obligated to pay Special Interest on such Note on such date of payment; and (ii) the amount of such Special Interest that is payable on such date of payment.  The Trustee will have no duty to determine whether any Special Interest is payable or the amount thereof.

(E)No Effect on Other Events of Default.  No election pursuant to this Section 7.03 with respect to a Reporting Event of Default will affect the rights of any Holder with respect to any other Event of Default, including with respect to any other Reporting Event of Default.

SECTION 7.04.OTHER REMEDIES.

(A)Trustee May Pursue All Remedies.  If an Event of Default occurs and is continuing, then the Trustee may pursue any available remedy to collect the payment of any amounts due with respect to the Notes or to enforce the performance of any provision of the Indenture or the Notes.

(B)Procedural Matters.  The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in such proceeding.  A delay or omission by the Trustee or any Holder in exercising any right or remedy following an Event of Default will not impair the right or remedy or constitute a waiver of, or acquiescence in, such Event of Default.  All remedies will be cumulative to the extent permitted by law.

SECTION 7.05.WAIVER OF PAST DEFAULTS.

An Event of Default pursuant to clause (i), (ii), (iv) or (vi) of Section 7.01(A) (that, in the case of clause (vi) only, results from a Default under any covenant that cannot be amended without the consent of each affected Holder), and a Default that could lead to such an Event of Default, can be waived only with the consent of each affected Holder.  Each other Default or Event of Default may be waived, on behalf of all Holders, by the Holders of a majority in aggregate principal amount of the Notes then outstanding.  If an Event of Default is so waived, then it will cease to exist.  If a Default is so waived, then it will be deemed to be cured and any Event of Default arising therefrom will be deemed not to occur.  However, no such waiver will extend to any subsequent or other Default or Event of Default or impair any right arising therefrom.

SECTION 7.06.CONTROL BY MAJORITY.

Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it.  However, the Trustee may refuse to follow any direction that conflicts with law, the Indenture or the Notes, or that, subject to Section 7.1 of the Base Indenture, the Trustee determines may be unduly prejudicial to the rights of other Holders (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 may involve the Trustee in liability, unless the Trustee is offered security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such direction.

56

SECTION 7.07.LIMITATION ON SUITS.

No Holder may pursue any remedy with respect to the Indenture or the Notes (except to enforce (x) its rights to receive the principal of, or the Fundamental Change Repurchase Price for, or interest on, any Notes; or (y) the Company’s obligations to convert any Notes pursuant to Article 5), unless:

(A)such Holder has previously delivered to the Trustee notice that an Event of Default is continuing;

(B)Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding deliver a written request to the Trustee to pursue such remedy;

(C)such Holder or Holders offer and, if requested, provide to the Trustee security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such request;

(D)the Trustee does not comply with such request within sixty (60) calendar days after its receipt of such request and such offer of security or indemnity; and

(E)during such sixty (60) calendar day period, Holders of a majority in aggregate principal amount of the Notes then outstanding do not deliver to the Trustee a direction that is inconsistent with such request.

A Holder of a Note may not use the Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.  The Trustee will have no duty to determine whether any Holder’s use of the Indenture complies with the preceding sentence.

SECTION 7.08.ABSOLUTE RIGHT OF HOLDERS TO INSTITUTE SUIT FOR THE ENFORCEMENT OF THE RIGHT TO RECEIVE PAYMENT AND CONVERSION CONSIDERATION.

Notwithstanding anything to the contrary in the Indenture or the Notes (but without limiting Section 8.01), the right of each Holder of a Note to receive payment or delivery, as applicable, of the principal of, or the Fundamental Change Repurchase Price for, or any interest on, or the Conversion Consideration due pursuant to Article 5 upon conversion of, such Note on or after the respective due dates therefor provided in the Indenture and the Notes, or to bring suit for the enforcement of any such payment or delivery on or after such respective due dates, will not be impaired or affected without the consent of such Holder.

SECTION 7.09.COLLECTION SUIT BY TRUSTEE.

The Trustee will have the right, upon the occurrence and continuance of an Event of Default pursuant to clause (i), (ii) or (iv) of Section 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for the total unpaid or undelivered principal of, or Fundamental Change Repurchase Price for, or interest on, or Conversion Consideration due pursuant to Article 5 upon conversion of, the Notes, as applicable, and, to the extent lawful, any Default Interest on any Defaulted Amounts, and such further amounts sufficient to cover the costs

57

and expenses of collection, including compensation provided for in Section 7.7 of the Base Indenture.

SECTION 7.10.TRUSTEE MAY FILE PROOFS OF CLAIM.

The Trustee has the right to (A) file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes) or its creditors or property and (B) collect, receive and distribute any money or other property payable or deliverable on any such claims.  Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to the Trustee for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to the Trustee pursuant to Section 7.7 of the Base Indenture.  To the extent that the payment of any such compensation, expenses, disbursements, advances and other amounts out of the estate in such proceeding, is denied for any reason, payment of the same will be secured by a lien on, and will be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding (whether in liquidation or under any plan of reorganization or arrangement or otherwise).  Nothing in the Indenture will be deemed to authorize the Trustee to authorize, consent to, accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.  The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ committee or other similar committee.

SECTION 7.11.PRIORITIES.

The Trustee will pay or deliver in the following order any money or other property that it collects pursuant to this Article 7 or is distributable in respect of the Company’s obligations under the Indenture after an Event of Default:

First:to the Trustee and its agents and attorneys for amounts due under the Base Indenture, including payment of all fees, compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second:to Holders for unpaid amounts or other property due on the Notes, including the principal of, or the Fundamental Change Repurchase Price for, or any interest on, or any Conversion Consideration due upon conversion of, the Notes, ratably, and without preference or priority of any kind, according to such amounts or other property due and payable on all of the Notes; and

Third:to the Company or such other Person as a court of competent jurisdiction directs.

The Trustee may fix a record date and payment date for any payment or delivery to the Holders pursuant to this Section 7.11, in which case the Trustee will instruct the Company to, and

58

the Company will, deliver, at least fifteen (15) calendar days before such record date, to each Holder and the Trustee a notice stating such record date, such payment date and the amount of such payment or nature of such delivery, as applicable.

SECTION 7.12.UNDERTAKING FOR COSTS.

In any suit for the enforcement of any right or remedy under the Indenture or the Notes or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking to pay the costs of such suit, and (B) assess reasonable costs (including reasonable attorneys’ fees) against any litigant party in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant party; provided, however, that this Section 7.12 does not apply to any suit by the Trustee, any suit by a Holder pursuant to Section 7.08 or any suit by one or more Holders of more than ten percent (10%) in aggregate principal amount of the Notes then outstanding.

Article 8.   AMENDMENTS, SUPPLEMENTS AND WAIVERS

This Article 8 will apply to the Notes in lieu of Article IX of the Base Indenture, which will be deemed to be replaced with this Article 8, mutatis mutandis.

SECTION 8.01.WITHOUT THE CONSENT OF HOLDERS.

Notwithstanding anything to the contrary in Section 8.02, the Company and the Trustee may amend or supplement the Indenture or the Notes without the consent of any Holder to:

(A)cure any ambiguity or correct any omission, defect or inconsistency in the Indenture or the Notes;

(B)add guarantees with respect to the Company’s obligations under the Indenture or the Notes;

(C)secure the Notes;

(D)add to the Company’s covenants or Events of Default for the benefit of the Holders or surrender any right or power conferred on the Company;

(F)enter into supplemental indentures pursuant to, and in accordance with, Section 5.09 in connection with a Common Stock Change Event;

(G)irrevocably elect or eliminate any Settlement Method or Specified Dollar Amount; provided, however, that no such election or elimination will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note pursuant to Section 5.03(A);

(H)evidence or provide for the acceptance of the appointment, under the Indenture, of

59

a successor Trustee;

(I)conform the provisions of the Indenture and the Notes to the “Description of Notes” section of the Company’s preliminary prospectus supplement, dated August 6, 2019, as supplemented by the related pricing term sheet, dated August 7, 2019;

(J)provide for or confirm the issuance of additional Notes pursuant to Section 2.02(B);

(K)comply with any requirement of the SEC in connection with effecting or maintaining the qualification of the Indenture or any supplemental indenture under the Trust Indenture Act, as then in effect;

(L)provide for any transfer restrictions that apply to any Notes issued under the Indenture (other than the Notes issued pursuant to the Underwriting Agreement, and any Notes issued in exchange therefor or in substitution thereof) that, at the time of their original issuance, constitute “restricted securities” within the meaning of Rule 144 under the Securities Act or that are originally issued in reliance upon Regulation S under the Securities Act;

(M)make any other change to the Indenture or the Notes that does not, individually or in the aggregate with all other such changes, adversely affect the rights of the Holders, as such, in any material respect.

At the written request of any Holder of a Note or owner of a beneficial interest in a Global Note, the Company will provide a copy of the “Description of Notes” section and pricing term sheet referred to in (I).

SECTION 8.02.WITH THE CONSENT OF HOLDERS.

(A)Generally.  Subject to Sections 8.01, 7.05 and 7.08 and the immediately following sentence, the Company and the Trustee may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, amend or supplement the Indenture or the Notes or waive compliance with any provision of the Indenture or the Notes.  Notwithstanding anything to the contrary in the foregoing sentence, but subject to subject to Section 8.01, without the consent of each affected Holder, no amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may:

(i)reduce the principal, or extend the stated maturity, of any Note;

(ii)reduce the Fundamental Change Repurchase Price for any Note or change the times at which, or the circumstances under which, the Notes will be repurchased by the Company;

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

(iv)make any change that adversely affects the conversion rights of any Note, other than as required by the Indenture;

(v)impair the rights of any Holder set forth in Section 7.08 (as such section is

60

in effect on the Issue Date);

(vi)change the ranking of the Notes in a manner that adversely affects any Holder;

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

(viii)reduce the amount of Notes whose Holders must consent to any amendment, supplement, waiver or other modification; or

(ix)make any direct or indirect change to any amendment, supplement, waiver or modification provision of the Indenture or the Notes that requires the consent of each affected Holder.

For the avoidance of doubt, pursuant to clauses (i), (ii), (iii) and (iv) of this Section 8.02(A), no amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may change the amount or type of consideration due on any Note (whether on an Interest Payment Date, Fundamental Change Repurchase Date or the Maturity Date or upon conversion, or otherwise), or the date(s) or time(s) such consideration is payable or deliverable, as applicable, without the consent of each affected Holder.

(B)Holders Need Not Approve the Particular Form of any Amendment.  A consent of any Holder pursuant to this Section 8.02 need approve only the substance, and not necessarily the particular form, of the proposed amendment, supplement or waiver.

SECTION 8.03.NOTICE OF AMENDMENTS, SUPPLEMENTS AND WAIVERS.

As soon as reasonably practicable after any amendment, supplement or waiver pursuant to Section 8.01 or 8.02 becomes effective, the Company will send to the Holders and the Trustee notice that (A) describes the substance of such amendment, supplement or waiver in reasonable detail and (B) states the effective date thereof; provided, however, that the Company will not be required to provide such notice to the Holders if such amendment, supplement or waiver is included in a current report or periodic report filed by the Company with the SEC within four (4) Business Days of its effectiveness.  The failure to send, or the existence of any defect in, such notice will not impair or affect the validity of such amendment, supplement or waiver.

SECTION 8.04.REVOCATION, EFFECT AND SOLICITATION OF CONSENTS; SPECIAL RECORD DATES; ETC.

(A)Revocation and Effect of Consents.  The consent of a Holder of a Note to an amendment, supplement or waiver will bind (and constitute the consent of) each subsequent Holder of any Note to the extent the same evidences any portion of the same indebtedness as the consenting Holder’s Note, subject to the right of any Holder of a Note to revoke (if not prohibited pursuant to Section 8.04(B)) any such consent with respect to such Note by delivering notice of revocation to the Trustee before the time such amendment, supplement or waiver becomes effective.

61

(B)Special Record Dates.  The Company may, but is not required to, fix a record date for the purpose of determining the Holders entitled to consent or take any other action in connection with any amendment, supplement or waiver pursuant to this Article 8.  If a record date is fixed, then, notwithstanding anything to the contrary in Section 8.04(A), only Persons who are Holders as of such record date (or their duly designated proxies) will be entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of whether such Persons continue to be Holders after such record date; provided, however, that no such consent will be valid or effective for more than one hundred and twenty (120) calendar days after such record date.

(C)Solicitation of Consents.  For the avoidance of doubt, each reference in the Indenture or the Notes to the consent of a Holder will be deemed to include any such consent obtained in connection with a repurchase of, or tender or exchange offer for, any Notes.

(D)Effectiveness and Binding Effect.  Each amendment, supplement or waiver pursuant to this Article 8 will become effective in accordance with its terms and, when it becomes effective with respect to any Note (or any portion thereof), will thereafter bind every Holder of such Note (or such portion).

SECTION 8.05.NOTATIONS AND EXCHANGES.

If any amendment, supplement or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion, require the Holder of such Note to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company on such Note and return such Note to such Holder.  Alternatively, at its discretion, the Company may, in exchange for such Note, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.3 of the Base Indenture, a new Note that reflects the changed terms.  The failure to make any appropriate notation or issue a new Note pursuant to this Section 8.05 will not impair or affect the validity of such amendment, supplement or waiver.

SECTION 8.06.TRUSTEE TO EXECUTE SUPPLEMENTAL INDENTURES.

The Trustee will execute and deliver any amendment or supplemental indenture authorized pursuant to this Article 8; provided, however, that the Trustee need not (but may, in its sole and absolute discretion) execute or deliver any such amendment or supplemental indenture that adversely affects the Trustee’s rights, duties, liabilities or immunities.  In executing any amendment or supplemental indenture, the Trustee will be entitled to receive, and (subject to Sections 7.1 and 7.2 of the Base Indenture) will be fully protected in relying on, an Officer’s Certificate and an Opinion of Counsel stating that (A) the execution and delivery of such amendment or supplemental indenture is authorized or permitted by the Indenture; and (B) in the case of the Opinion of Counsel, such amendment or supplemental indenture is valid, binding and enforceable against the Company in accordance with its terms.

SECTION 8.07.COMPLIANCE WITH TRUST INDENTURE ACT.

Every amendment to this Supplemental Indenture or the Notes required to be set forth in a supplemental indenture shall be set forth in a supplemental indenture hereto that complies with the

62

Trust Indenture Act as then in effect.

Article 9.   SATISFACTION AND DISCHARGE

This Article 9 will apply to the Notes in lieu of Article VIII of the Base Indenture, which will be deemed to be replaced with this Article 9, mutatis mutandis.  For the avoidance of doubt, the Notes will not be subject to legal or covenant defeasance pursuant to Section 8.3 or 8.4 of the Base Indenture.

SECTION 9.01.TERMINATION OF COMPANY’S OBLIGATIONS.

The Indenture will be discharged, and will cease to be of further effect as to all Notes issued under the Indenture, when:

(A)all Notes then outstanding (other than Notes replaced pursuant to Section 2.8 of the Base Indenture) have (i) been delivered to the Trustee for cancellation; or (ii) become due and payable (whether on a Fundamental Change Repurchase Date, the Maturity Date, upon conversion or otherwise) for an amount of cash or Conversion Consideration, as applicable, that has been fixed;

(B)the Company has caused there to be irrevocably deposited with the Trustee, or with the Paying Agent (or, with respect to Conversion Consideration, the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered to the Holders, cash (or, with respect to Notes to be converted, Conversion Consideration) sufficient to satisfy all amounts or other property due on all Notes then outstanding (other than Notes replaced pursuant to Section 2.8 of the Base Indenture);

(C)the Company has paid all other amounts payable by it under the Indenture; and

(D)the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that the conditions precedent to the discharge of the Indenture have been satisfied;

provided, however, that Article VII of the Base Indenture and Section 10.01 and the Company’s obligations thereunder will survive such discharge and, until no Notes remain outstanding, Section 2.12 of the Base Indenture and the obligations of the Trustee, the Paying Agent and the Conversion Agent with respect to money or other property deposited with them will survive such discharge.

At the Company’s request, the Trustee will acknowledge the satisfaction and discharge of the Indenture.

SECTION 9.02.REPAYMENT TO COMPANY.

Subject to applicable unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will promptly notify the Company if there exists (and, at the Company’s request, promptly deliver to the Company) any cash, Conversion Consideration or other property held by any of them for payment or delivery on the Notes that remain unclaimed two (2) years after the date on which such payment or delivery was due.  After such delivery to the Company,

63

the Trustee, the Paying Agent and the Conversion Agent will have no further liability to any Holder with respect to such cash, Conversion Consideration or other property, and Holders entitled to the payment or delivery of such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor of the Company.

SECTION 9.03.REINSTATEMENT.

If the Trustee, the Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it pursuant to Section 9.01 because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains or otherwise prohibits such application, then the discharge of the Indenture pursuant to Section 9.01 will be rescinded; provided, however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to the Holders thereof, then the Company will be subrogated to the rights of such Holders to receive such cash or other property from the cash or other property, if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable.

Article 10.   MISCELLANEOUS
