(c) With respect to the Notes, Section 3.07 of the Base Indenture shall apply with respect to (i) (x) Defaulted Amounts and (y) the Holder otherwise entitled to receive such Defaulted Amounts in the same manner as it applies with respect to (ii) (x) Defaulted Interest and (y) the Holder on the related Regular Record Date.

Section 3.04. Exchange and Registration of Transfer of Notes; Depositary.

(a) Notwithstanding the provisions of ‎Section 3.05 of the Base Indenture, none of the Company, the Trustee or the Registrar shall be required to exchange Notes for other Notes or register a transfer of (i) any Notes surrendered for conversion in accordance with Article 8 for Common Stock, or, if a portion of any Note is surrendered for conversion for Common Stock, such portion thereof surrendered for conversion in accordance with Article 8 or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 9.

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law or as otherwise provided in Section 3.04(c), all Notes shall be represented by one or more Global Notes (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture and the Applicable Procedures.

(c) The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as Custodian. A Global Note may be transferred, in whole or in part, only to another nominee of the Depositary or to a successor Depositary or its nominee or in accordance with the immediately succeeding paragraph.

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

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 3.04(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

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

(d) The Company shall cause to be kept an office or agency where Notes may be presented for conversion in accordance with Article 8 of this Third Supplemental Indenture (the “Conversion Agent”). The Company initially appoints the Trustee as Conversion Agent. The Company may have one or more additional Conversion Agents with respect to the Notes. If the Company fails to maintain a Conversion Agent, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Conversion Agent; provided that neither the Company nor an Affiliate of the Company shall act as Conversion Agent in connection with the discharge of the Indenture under Article 4 of this Third Supplemental Indenture.

(e) For the avoidance of doubt, the penultimate paragraph of ‎Section 3.05 of the Base Indenture shall not apply to the Notes.

Section 3.05. Mutilated, Destroyed, Lost or Stolen Notes. Solely for purposes of the Notes, the third and fourth paragraphs of ‎Section 3.06 of the Base Indenture are hereby deleted in their entirety and replaced with the following: “In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article 8 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company and to the Trustee such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent of the destruction, loss or theft of such Note and of the ownership thereof. No service charge shall be imposed by the Company, the Trustee, the Registrar, any co-Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen.”

Section 3.06. Additional Notes; Repurchases. Unless an Event of Default has occurred, the Company may, without the consent of the Holders and notwithstanding Section 3.01, reopen the Indenture and issue additional Notes hereunder with the same terms and with the same CUSIP number as the Notes initially issued hereunder in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 3.09 of the Base Indenture.

Section 3.07. Cancellation of Notes Paid, Converted, Etc. Section 3.09 of the Base Indenture is hereby amended with respect to the Notes by replacing the first sentence thereof with the sentence: “All Notes surrendered for payment, repurchase, registration of transfer or exchange or conversion shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it.”

Section 6.02. Additional Interest. Notwithstanding anything in the Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or (ii) the Company’s failure to comply with its obligations as set forth in ‎Section 5.03(b) shall, at the Company’s option, for the 365 days after the occurrence of such an Event of Default consist exclusively of the right to receive Additional Interest on the Notes at an annual rate equal to (i) 0.25% of the principal amount of the Notes outstanding during the 185-day period following the Event of Default and (ii) 0.50% of the principal amount of the Notes outstanding during the 180-day period beginning on the 186th day following the Event of Default. In the event the Company does not elect to pay the Additional Interest upon an Event of Default in accordance with this paragraph, the Notes will be subject to acceleration as provided in Section 6.01(b) above. The Additional Interest will accrue on all outstanding Notes from, and including, the date on which an Event of Default relating to a failure to comply with the obligations in ‎Section 5.03(b) first occurs to, and including, the 365th day thereafter (or such earlier date on which the Event of Default relating to the reporting obligations shall have been cured or waived). On the 366th day, if such Event of Default is continuing, such Additional Interest will cease to accrue and the Notes will be subject to acceleration as provided in Section 6.01(b) above. The provisions of the Indenture described in this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. In no event shall Additional Interest accrue at a rate in excess of the applicable rate specified above, regardless of the number of events or circumstances giving rise to requirements to pay such Additional Interest pursuant to this paragraph. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this ‎Section 6.02 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be subject to acceleration as provided in ‎Section 6.01(b) above.

In order to elect to pay Additional Interest as the sole remedy during the first 365 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 365-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in ‎Section 6.01(b) above.

Section 6.03. Rescission and Annulment. The Holders of a majority in aggregate principal amount of the Notes outstanding may, by written notice to the Company and the Trustee, after a declaration of acceleration, but before a judgment or decree for payment of the money due has been obtained by the Trustee, rescind and annul such declaration if:

(a) The Company has paid (or deposited with the Trustee a sum sufficient to pay) (i) all overdue interest on all Notes; (ii) the principal amount of any Notes that have become due otherwise than by such declaration of acceleration; (iii) to the extent that payment of such interest is lawful, interest upon overdue interest; and (iv) all sums paid or advanced by the Trustee under the Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and

(b) All Events of Default, other than the non-payment of the principal amount and any accrued and unpaid interest that have become due solely by such declaration of acceleration, have been cured or waived.

Section 6.04. Notice of Defaults. Within 90 calendar days of becoming aware of the occurrence of any Default, the Trustee shall give notice to Holders of the Notes notice of all uncured Defaults known to it. The Trustee may withhold notice to the Holders of the Notes of any Default, except Defaults in payment of principal or interest on the Notes or Defaults in the failure to deliver the consideration due upon conversion, if the Trustee, in good faith, determines that the withholding of such notice is in the interest of the Holders. Section 6.02 of the Base Indenture shall not apply to the Notes.

Section 6.05. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to Article 5 of the Base Indenture with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 6.07 of the Base Indenture;

SECOND: In case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto;

THIRD: In case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, any cash due upon conversion) and accrued and unpaid interest; and

FOURTH: To the payment of the remainder, if any, to the Company.

Section 6.06. Unconditional Right of Holders to Receive Principal, Interest and Consideration Due upon Conversion. Notwithstanding any other provision of this Indenture and any provision of any Note, each Holder shall have the right to receive payment or delivery, as the case may be, of (a) the principal of, (b) accrued and unpaid interest, if any, on, and (c) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be.

Section 6.07. Waiver of Past Defaults. The Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (a) a Default in the payment of accrued and unpaid interest, if any, on, or the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Notes when due, (b) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (c) a Default in respect of a covenant or provision hereof which under ‎Article 7 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this ‎Section 6.05, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

(i) modify any of the provisions of this Section 7.03 or of Sections 6.03 or 6.07 hereof, except to increase the percentage of the aggregate principal amount of the Notes then outstanding that is required in connection with any rescission, annulment, waiver or consent thereunder or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Note affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to “Trustee” and concomitant changes in this ‎Section 7.03, or the deletion of this proviso, in accordance with the requirements of 6.11 of the Base Indenture and ‎Section 7.02(k) hereof.

It shall not be necessary for any Act of Holders of Notes under this ‎Section 7.03 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture.

ARTICLE 8
Conversion of Notes

Section 8.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 8, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple of $1,000 in excess thereof) of such Note (i) subject to satisfaction of the conditions described in ‎Section 8.01(b), at any time prior to the close of business on the Business Day immediately preceding July 1, 2023 under the circumstances and during the periods set forth in ‎Section 8.01(b), and (ii) regardless of the conditions described in ‎Section 8.01(b), on or after July 1, 2023 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 8.9364 shares of Common Stock (subject to adjustment as provided in this Article ‎8, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of ‎Section 8.02, the “Conversion Obligation”).

(b) (i) Prior to the close of business on the Business Day immediately preceding July 1, 2023, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock on each such Trading Day and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the Conversion Rate on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent and the Company fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee).

(ii) If, prior to the close of business on the Business Day immediately preceding July 1, 2023, the Company elects to:

(A) distribute to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the declaration date for such distribution, to purchase shares of the Common Stock at a price per share that is less than the average Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Days immediately preceding, but excluding, the declaration date for such distribution; or

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

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution. Once the Company has given such notice, a Holder may surrender its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time.

Notwithstanding the immediately preceding paragraph, a Holder of the Notes shall not be permitted to so surrender its Notes for conversion if such Holder is entitled to participate (solely as a result of holding the Notes), at the same time and upon the same terms as Holders of the Common Stock, in such distribution, without having to convert its Notes, as if it held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(iii) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding July 1, 2023, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 9.01, or if the Company is a party to a consolidation, merger, statutory share exchange or sale, lease or transfer of the consolidated assets of the Company and its Subsidiaries substantially as an entirety that occurs prior to the close of business on the Business Day immediately preceding July 1, 2023, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the date that is 30 Scheduled Trading Days prior to the anticipated effective date of the transaction or event (or, if later, the Business Day after the Company gives notice of such transaction or event) until 35 Trading Days after the actual effective date of such transaction or event or, if such transaction or event also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) by mail or electronic delivery (i) as promptly as practicable following the date the Company publicly announces such transaction or event but in no event less than 30 Scheduled Trading Days prior to the anticipated effective date of such transaction or event; or (ii) if the Company has not publicly announced such transaction or event at least 30 Scheduled Trading Days prior to the anticipated effective date of such transaction or event, within two Business Days of the date upon which the Company publicly announces such transaction or event, but in no event later than the actual effective date of such transaction or event.

(iv) Prior to the close of business on the Business Day immediately preceding July 1, 2023, a Holder may surrender all or a portion of its Notes for conversion during any calendar quarter commencing after the calendar quarter ending on December 31, 2016 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day as determined by the Company. The Company shall determine at the beginning of each calendar quarter commencing after December 31, 2016 whether the Notes may be surrendered for conversion in accordance with this clause ‎(iv) and shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) if the Notes become convertible in accordance with this clause (iv).

Section 8.02. Conversion Procedure; Settlement Upon Conversion.

(a) Subject to this Section 8.02, Section 8.03(b) and Section 8.07(a), upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with Section 8.02(j) (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with Section 8.02(j) (“Combination Settlement”), at its election, as set forth in this Section 8.02.

(i) All conversions for which the relevant Conversion Date occurs on or after July 1, 2023 shall be settled using the same Settlement Method.

(ii) Except for any conversions for which the relevant Conversion Date occurs on or after July 1, 2023, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates.

(iii) If, in respect of any Conversion Date (or the period described in the third immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company shall deliver such Settlement Notice to converting Holders and the Trustee no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs during the period from, and including, July 1, 2023 to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, no later than July 1, 2023). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000.

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

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

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 20 consecutive Trading Days during the related Observation Period; and

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

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

(b) Subject to Section 8.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest (excluding any Additional Interest) payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 8.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest (but excluding any Additional Interest) payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 8.02(h). The Trustee (and, if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 8 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 9.02, except to the extent that a portion of such Holder’s Notes is not subject to such Fundamental Change Repurchase Notice.

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

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date that the Holder has complied with the requirements set forth in subsection (b) above (the “Conversion Date”). Except as set forth in ‎‎Section 8.03(b), Section 8.04(c)(ii), Section 8.04(e) and ‎Section 8.07(a), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following the last Trading Day of the Observation Period, in the case of any other Settlement Method; provided, however, that, with respect to any Conversion Date that occurs on or after the Regular Record Date immediately preceding the Maturity Date, the Company shall deliver the consideration due upon conversion on the Maturity Date. If any shares of Common Stock are due to converting Holders, the Company shall cause to be issued and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

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

(e) The Company shall pay any transfer or similar taxes due upon conversion other than any tax or duty that may be payable relating to any transfer involved in the issuance or delivery of shares of Common Stock, if any, due upon conversion in a name other than that of the converting Holder, which such taxes shall be the obligation of the Holder. Shares of Common Stock shall be issued and delivered only after all applicable transfer or similar taxes, if any, payable by the Holder have been paid in full.

(f) Except as provided in Section 8.04, no adjustment shall be made for dividends on any shares of Common Stock delivered upon the conversion of any Note as provided in this ‎ Article ‎8.

(g) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

(h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest (excluding Additional Interest), if any, except as set forth below. The Company’s settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest and accrued tax original issue discount, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. With respect to any conversion of the Notes, accrued and unpaid interest will be deemed to be paid first out of any cash paid upon conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the corresponding Interest Payment Date must be accompanied by funds equal to the amount of interest (excluding any Additional Interest) payable on the Notes so converted on the corresponding Interest Payment Date; provided that no such payment shall be required (1) for conversions following the close of business on the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any Defaulted Interest, if any Defaulted Interest exists at the time of conversion with respect to such Note.

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

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

Section 8.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.

(a) (i) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the close of business on the second Scheduled Trading Day immediately preceding the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition of Fundamental Change, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”).

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 8.02 based on the Conversion Rate as increased to reflect the Additional Shares pursuant to the table below; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause ‎(b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Share Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Share Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Share Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause ‎(b) of the definition of Fundamental Change, the Share Price shall be the cash amount paid per share. Otherwise, the Share Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Company’s Board of Directors shall make appropriate adjustments to the Share Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, effective date (as such term is used in Section 8.04) or expiration date of the event occurs during such five consecutive Trading Day period.

(d) The Share Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Share Prices shall equal the Share Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in ‎Section 8.04.

(e) The following table sets forth the number of Additional Shares by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this ‎Section 8.03 for each Share Price and Effective Date set forth below:

Share Price

Effective Date	$82.89	$85.00	$90.00	$95.00	$100.00	$111.90	$120.00	$130.00	$140.00	$150.00

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

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

(ii) if the Share Price is greater than $150.00 per share (subject to adjustment in the same manner as the Share Prices set forth in the column headings of the table above pursuant to subsection ‎(d) above), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Share Price is less than $82.89 per share (subject to adjustment in the same manner as the Share Prices set forth in the column headings of the table above pursuant to subsection ‎(d) above), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 12.0641, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 8.04.

(f) Nothing in this ‎Section 8.03 shall prevent an adjustment to the Conversion Rate pursuant to ‎Section 8.04 in respect of a Make-Whole Fundamental Change.

Section 8.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this ‎Section 8.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

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

where,

CR₁ =

the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution or the effective date of such share split or combination, as the case may be;

CR₀ =

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

OS₀=

the number of shares of Common Stock outstanding immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution or the effective date of such share split or combination;

OS₁ =

the number of shares of Common Stock that would be outstanding immediately after, and solely as a result of, such dividend, distribution, share split or combination, as the case may be.

Any adjustment made under this ‎Section 8.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 8.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date that the Company’s Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company distributes to all or substantially all holders of its Common Stock any rights, options or warrants entitling them to purchase, for a period of 45 calendar days or less from the declaration date for such distribution, Common Stock at a price per share less than the average Last Reported Sale Price of the Common Stock for the ten consecutive Trading Days immediately preceding, but excluding, the declaration date for such distribution, the Conversion Rate will be increased based on the following formula:

where,

CR₁ =

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

CR₀ =

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

OS₀ =

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

X =

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

Y =

the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding, but excluding, the declaration date for such distribution.

Any increase made under this Section 8.04(b) will be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such distribution had not occurred.

For the purpose of this Section 8.04(b) and for the purpose of Section 8.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Days immediately preceding, but excluding, the declaration date for such distribution, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable upon exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Company’s Board of Directors.

(c) (i) If the Company distributes shares of the Company’s capital stock, evidences of its indebtedness or other of the Company’s securities, assets or property to all or substantially all holders of its Common Stock, excluding (1) dividends or distributions as to which an adjustment is required to be effected pursuant to‎ Section 8.04(a) or ‎Section 8.04(b), (2) the initial distribution of rights issued pursuant to a shareholders rights plan; provided that such rights plan provides for the issuance of such rights with respect to the shares of Common Stock issued upon conversion of the Notes; (3) dividends or distributions paid exclusively in cash, and (4) Spin-Offs as to which the provisions set forth below in Section 8.04(c)(ii) shall apply (any of such shares, evidences of indebtedness or other of the Company’s securities, assets or property, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

where,

CR₁ =

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

CR₀ =

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

SP₀ =

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

FMV =

the fair market value (as determined by the Company’s Board of Directors) of the Distributed Property with respect to each outstanding share of Common Stock as of the Ex-Dividend Date for such distribution.

Any increase made under this Section 8.04(c)(i) will become effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), or if the difference between “SP₀” and “FMV” is less than $1.00, in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Company’s Common Stock without having to convert its Notes, the amount and kind of Distributed Property that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.

(ii) With respect to an adjustment pursuant to this ‎Section 8.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that will be, upon distribution, listed on a U.S. national or regional securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

where,

CR₁ =

Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for the Spin-Off;

CR₀ =

the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for the Spin-Off;

FMV =

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

MP₀ =

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

Any adjustment to the Conversion Rate under this Section 8.04(c)(ii) will be made immediately after the open of business on the day after the last day of the Valuation Period, but shall be given effect as of the open of business on the Ex-Dividend Date for the Spin-Off. Because the Company shall make the adjustment to the Conversion Rate at the end of the Valuation Period with retroactive effect, the Company shall delay the settlement of any Notes where the Conversion Date (in the case of Physical Settlement) or the final day of the related Observation Period (in the case of cash settlement or combination settlement) occurs during the Valuation Period. In such event, the Company shall deliver the consideration due upon conversion on the third Business Day immediately following the last day of the Valuation Period.

(d) If the Company pays any cash dividends or distributions exclusively in cash to all or substantially all holders of the Common Stock, the Conversion Rate shall be increased based on the following formula:

where,

CR₁ =

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

CR₀ =

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

SP₀ =

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

DTA =

the dividend threshold amount, which shall equal $1.25 per share in any quarter; and

C =

the amount in cash per share distributed to holders of the Common Stock.

The dividend threshold amount is subject to adjustment on an inversely proportional basis whenever the Conversion Rate is adjusted; provided that no adjustment will be made to the dividend threshold amount for any adjustment to the Conversion Rate under this Section 8.04(d). If an adjustment is required to be made as set forth in this Section 8.04(d) as a result of a distribution that is not a regular quarterly dividend, the dividend threshold amount will be deemed to be zero.

Any increase pursuant to this ‎Section 8.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Company’s Board of Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), or if the difference between “SP₀” and “C” is less than $1.00, in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock without having to convert its Notes, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such cash dividend or distribution.

Notwithstanding the foregoing, if the application of the formula in this Section 8.04(d) in respect of any cash dividend or distribution would result in a decrease in the Conversion Rate (other than any readjustment of the Conversion Rate as provided in the immediately preceding paragraph in the event the Company’s Board of Directors determines not to make or pay any previously declared dividend or distribution), then no adjustment to the Conversion Rate will be made in respect of such dividend or distribution.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires (the “Averaging Period”), the Conversion Rate will be increased based on the following formula:

where,

CR₁ =

the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the date such tender offer or exchange offer expires;

CR₀ =

the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender offer or exchange offer expires;

AC =

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

SP₁ =

the average of the Last Reported Sale Prices of the Common Stock over the Averaging Period;

OS₁ =

the number of shares of Common Stock outstanding immediately after the close of business on the date such tender or exchange offer expires (after giving effect to such tender offer or exchange offer); and

OS₀=

the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to such tender offer or exchange offer).

Any adjustment to the Conversion Rate under this ‎Section 8.04(e) will be made immediately prior to the open of business on the day following the last day of the Averaging Period, but will be given effect as of the open of business on the Trading Day next succeeding the date such tender offer or exchange offer expires. Because the Company shall make the adjustment to the Conversion Rate at the end of the Averaging Period with retroactive effect, the Company shall delay the settlement of any Notes where the Conversion Date (in the case of Physical Settlement) or the final day of the related Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the Averaging Period. In such event, the Company shall deliver the consideration due upon conversion on the third Business Day immediately following the last day of the Averaging Period.

(f) Notwithstanding this ‎Section 8.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under ‎Section 8.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this ‎Section 8.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

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

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 8.04, and to the extent permitted by applicable law and subject to the applicable rules of The New York Stock Exchange, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Company’s Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of The New York Stock Exchange, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Security Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i) Notwithstanding anything to the contrary in this Article 8, the Conversion Rate shall not be adjusted:

(i) On account of any stock repurchases that are not tender offers referred to in Section 8.04(e), including structured or derivative transactions or transactions pursuant to a share repurchase program approved by the Company’s Board of Directors or otherwise.

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

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

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

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

(vi) for accrued and unpaid interest, if any; or

(vii) for an event otherwise requiring an adjustment as set forth in this Section 8.04, if such event is not consummated.

(j) All calculations and other determinations under this Article ‎8 shall be made by the Company (or by the Board of Directors of the Company, if so specified) and shall be made to the nearest one-ten thousandth (1/10,000) of a share.

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect.

(l) For purposes of this Section 8.04, the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in its treasury, but shall include shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. In addition, in the event of any adjustments to the Conversion Rate as set forth in this‎ Section 8.04, the Company shall issue a press release through Business Wire containing the relevant information and make such information available on its website or through another public medium as it may use at that time.

(m) Notwithstanding anything to the contrary in this Indenture or the Notes, the Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate. The Company shall carry forward any adjustment that is less than 1% of the Conversion Rate, take such carried-forward adjustments into account in any subsequent adjustment, and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than 1%, (a) annually on the anniversary of the first date of issue of the Notes, (b) in the case of any Note to which Physical Settlement applies, upon the Conversion Date, and in the case of any Note to which Cash Settlement or Combination Settlement applies, on each Trading Day of the applicable Observation Period and (c) at least 10 Business Days prior to the Maturity Date or any Fundamental Change Repurchase Date, unless such adjustment has already been made.

Section 8.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over, or based on, a span of multiple days (including, without limitation, an Observation Period, Valuation Period or Averaging Period), the Company shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, effective date or expiration date, as the case may be, of the event occurs at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. For the avoidance of doubt, the adjustments made pursuant to this Section 8.05 will be made, solely to the extent the Company determines in the Company’s good faith judgment that any such adjustment is necessary, without duplication of any adjustment made pursuant to the provisions set forth under Section 8.04.

Section 8.06. Reservation of Common Stock. The Company shall provide, free from preemptive rights, out of the Company’s authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (expressed in thousands and assuming delivery of the maximum number of Additional Shares pursuant to Section 8.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable).

Section 8.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock.

(a) In the case of:

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

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

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an entirety or

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of common stock, other securities or other property or assets (including cash or any combination thereof) that a Holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under ‎Section 7.02(a) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 8.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 8.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with ‎Section 8.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will become convertible shall be deemed to be (x) the weighted average of the types and amounts of consideration received by the holders of the Common Stock that affirmatively make such an election or (y) if no holders of the Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of the Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock.

If the holders of the Common Stock receive only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 8.03), multiplied by the price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

Such supplemental indenture described in the third immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 8. If, in the case of any Merger Event, the Reference Property includes shares of common stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing entity, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Company’s Board of Directors shall reasonably consider necessary by reason of the foregoing.

(b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 8.07, the Company shall promptly deliver to the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or assets that will comprise a unit of Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders.

(c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 8.07. None of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in ‎Section 8.01 and ‎Section 8.02 prior to the effective date of such Merger Event.

(d) The above provisions of this Section shall similarly apply to successive Merger Events.

Section 8.08. Certain Covenants. (a) The Company covenants that all shares of Common Stock delivered upon conversion of Notes will be fully paid and non-assessable and free from all taxes, liens and charges with respect to the issue and delivery thereof.

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

Section 8.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue or of the Company to transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 8.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such ‎Section 8.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of ‎Section 6.03 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Section 8.10. Shareholder Rights Plans. To the extent that the Company has a shareholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and any certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case, as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property as provided in Section 8.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

ARTICLE 9
Repurchase of Notes at Option of Holders

Section 9.01. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior to the Maturity Date, each Holder of Notes shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000 in excess thereof, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 Business Days nor more than 35 Business Days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of Notes of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 9.

(b) Repurchases of Notes under this Section 9.01 shall be made, at the option of the Holder thereof, upon:

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

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

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

(i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

(ii) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiples of $1,000 in excess thereof; and

(iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture;

provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this ‎Section 9.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with ‎Section 9.02.

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

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

(i) the events causing the Fundamental Change;

(ii) the date of the Fundamental Change;

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 9;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

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

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

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

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 9.01.

At the Company’s request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

Section 9.02. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 9.02 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted,

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

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

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

[FORM OF REVERSE OF NOTE]

Macquarie Infrastructure Corporation
2.00% Convertible Senior Note due 2023

This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.00% Convertible Senior Notes due 2023 (the “Notes”), limited to the aggregate principal amount of $350,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Underwriters pursuant to the exercise of their over-allotment option as set forth in the Underwriting Agreement) all issued or to be issued under and pursuant to a Third Supplemental Indenture dated as of October 13, 2016 (the “Third Supplemental Indenture”), between the Company and Xxxxx Fargo Bank, National Association (the “Trustee”), which amends and supplements the Indenture dated as of July 15, 2014 between the Company and the Trustee (the “Base Indenture” and, as amended and supplemented by the Third Supplemental Indenture and from time to time with respect to the Notes, the “Indenture”). Reference is hereby made to the Indenture for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Company may, without the consent of the Holders, reopen the Indenture and issue additional Notes with the same terms and with the same CUSIP number as the Notes initially issued thereunder in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued thereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

A-6

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal of, accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money or shares of Common Stock, as the case may be, herein prescribed.

The Notes are issuable in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion of Notes being different from the name of the Holder of the old Notes surrendered for such conversion.

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

This Note shall be governed by, and construed in accordance with, the laws of the State of New York.

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

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

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