For the avoidance of doubt, if an Interest Payment Date is not a Business Day within the meaning ofSection 2.04(C) and such Fundamental Change Repurchase Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance withSection 2.04(C), on the next Business Day to Holders at of the Close of Business on the immediately preceding Regular Record Date; and (y) the Fundamental Change Repurchase Price will include interest on Notes to be repurchased from, and including, such Interest Payment Date.

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

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

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

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

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

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

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

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

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

(2) the principal amount of such Note to be repurchased, which must

- 22 -

be an Authorized Denomination; and

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

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

(iii)Withdrawal of Fundamental Change Repurchase Notice. A Holder that has delivered a Fundamental Change Repurchase Notice with respect to Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent at any time before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date (or, if the Company fails to pay the related Fundamental Change Repurchase Price for such Note when due, at any time before such Fundamental Change Repurchase Price is paid in full). Such withdrawal notice must state:

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

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

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

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

Upon receipt of any such withdrawal notice with respect to a Note (or any portion thereof), the Paying Agent will (x) promptly deliver a copy of such withdrawal notice to the Company; and (y) if such Note is surrendered to the Paying Agent, cause such Note (or such portion thereof in accordance withSection 2.08, treating such Note as having been then surrendered for partial repurchase in the amount set forth in such withdrawal notice as remaining subject to repurchase) to be returned to the Holder thereof (or, if applicable with respect to any Global Note, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Note in accordance with the Depositary Procedures).

(G)Payment of the Fundamental Change Repurchase Price. Without limiting the Company’s obligation to deposit the Fundamental Change Repurchase Price within the time proscribed bySection 3.01(B), the Company will cause the Fundamental Change Repurchase

- 23 -

Price for a Note (or portion thereof) to be repurchased pursuant to a Repurchase Upon Fundamental Change to be paid to the Holder thereof on or before the later of (i) the applicable Fundamental Change Repurchase Date; and (ii) the date (x) such Note is delivered to the Paying Agent (in the case of a Physical Note) or (y) the Depositary Procedures relating to the repurchase, and the delivery to the Paying Agent, of such Holder’s beneficial interest in such Note to be redeemed are complied with (in the case of a Global Note). For the avoidance of doubt, interest payable pursuant to the proviso toSection 4.02(D) on any Note to be repurchased pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to such proviso regardless of whether such Note is delivered or such Depositary Procedures are complied with pursuant to the first sentence of thisSection 4.02(G).

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

(I)No Requirement to Conduct an Offer to Repurchase Notes if the Fundamental Change Results in the Notes Becoming Convertible into an Amount of Cash Exceeding the Fundamental Change Repurchase Price. Notwithstanding anything to the contrary in thisSection 4.02, the Company will not be required to send a Fundamental Change Notice pursuant toSection 4.02(E), or offer to repurchase or repurchase any Notes pursuant to thisSection 4.02, in connection with a Fundamental Change occurring pursuant to clause (B)(ii) (or pursuant to clause (A) that also constitutes a Fundamental Change occurring pursuant to clause (B)(ii)) of the definition thereof, if (i) such Fundamental Change constitutes a Common Stock Change Event for which all or part of the Reference Property consists of cash in U.S. dollars; (ii) immediately after such Fundamental Change, the Notes become convertible, pursuant toSection 5.09(A) and, if applicable,Section 5.07, into consideration that includes such cash in an amount per $1,000 aggregate principal amount of Notes that equals or exceeds the Fundamental Change Repurchase Price per $1,000 aggregate principal amount of Notes (calculated assuming that the same includes accrued interest to, but excluding, the latest possible Fundamental Change Repurchase Date for such Fundamental Change); and (iii) the Company timely sends the notice relating to such Fundamental Change required pursuant toSection 5.01(C)(i)(3)(b).

(J)Compliance with Applicable Securities Laws. The Company will comply in all material respects with all federal and state securities laws in connection with a Repurchase Upon Fundamental Change (including complying with the tender offer rules under the Exchange Act and filing any required Schedule TO, to the extent applicable) so as to permit effecting such Repurchase Upon Fundamental Change in the manner set forth in the Indenture. However, to the extent that the provisions of any securities laws or regulations adopted after the date on which the Notes are first issued conflict with the provisions of the Indenture relating to the Company’s obligations to effect a Repurchase Upon Fundamental Change, the Company will comply with such applicable securities laws and regulations and will not be deemed to have breached its obligations under such provisions of the Indenture by virtue of such conflict.

- 24 -

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

Section 4.03. RIGHTOFTHE COMPANYTO REDEEMTHE NOTES.

(A)No Right to Redeem Before September 15, 2022. The Company may not redeem the Notes at its option at any time before September 15, 2022.

(B)Right to Redeem the Notes on or After September 15, 2022. Subject to the terms of thisSection 4.03, the Company has the right, at its election, to redeem all, or any portion in an Authorized Denomination, of the Notes, at any time and from time to time, on a Redemption Date occurring on or after September 15, 2022 and, in the case of any partial Redemption, on or before the fortieth (40th) Scheduled Trading Day before the Maturity Date, for a cash purchase price equal to the Redemption Price, but only if the Last Reported Sale Price per share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price on each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the Trading Day immediately before the Redemption Notice Date for such Redemption.

(C)Redemption Prohibited in Certain Circumstances. If the principal amount of the Notes has been accelerated (other than as a result of a failure to make the payment of the related Redemption Price, and any related interest pursuant to the proviso toSection 4.03(E), on such Redemption Date) and such acceleration has not been rescinded on or before the Redemption Date, then (i) the Company may not call for Redemption or otherwise redeem any Notes pursuant to thisSection 4.03; and (ii) the Company will cause any Notes theretofore surrendered for such Redemption to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interests in such Notes in accordance with the Depositary Procedures).

(D)Redemption Date. The Redemption Date for any Redemption will be a Business Day of the Company’s choosing that is no more than sixty-five (65), nor less thanforty-five (45), Scheduled Trading Days after the Redemption Notice Date for such Redemption.

(E)Redemption Price. The Redemption Price for any Note called for Redemption is an amount in cash equal to the principal amount of such Note plus accrued and unpaid interest on such Note to, but excluding, the Redemption Date for such Redemption;provided,however, that if such Redemption Date is after a Regular Record Date and on or before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Redemption, to receive, on or before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Redemption Date is before such Interest Payment Date); and (ii) the Redemption Price will not include accrued and unpaid interest on such Note to, but excluding, such Redemption Date. For the avoidance of doubt, if an Interest Payment

- 25 -

Date is not a Business Day within the meaning ofSection 2.04(C) and such Redemption Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance withSection 2.04(C), on the next Business Day to Holders at of the Close of Business on the immediately preceding Regular Record Date; and (y) the Redemption Price will include interest on Notes to be redeemed from, and including, such Interest Payment Date.

(F)Redemption Notice. To call any Notes for Redemption, the Company must send to each Holder (and to any beneficial owner of a Global Note, if required by applicable law), the Trustee and the Paying Agent a written notice of such Redemption (a “Redemption Notice”).

Such Redemption Notice must state:

(i) that the Notes have been called for Redemption, briefly describing the Company’s Redemption right under the Indenture;

(ii) the Redemption Date for such Redemption;

(iii) the Redemption Price per $1,000 principal amount of Notes for such Redemption (and, if the Redemption Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso toSection 4.03(E));

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

(v) that Notes called for Redemption may be converted at any time before the Close of Business on the Business Day immediately before the Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such time as the Company pays such Redemption Price in full);

(vi) the Conversion Rate in effect on the Redemption Notice Date for such Redemption;

(vii) the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after such Redemption Notice Date and before such Redemption Date;

(viii) that Notes called for Redemption must be delivered to the Paying Agent (in the case of Physical Notes) or the Depositary Procedures must be complied with (in the case of Global Notes) for the Holder thereof to be entitled to receive the Redemption Price; and

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

On or before the Redemption Notice Date, the Company will send a copy of such Redemption Notice to the Trustee and the Paying Agent.

- 26 -

(G) If less than all Notes then outstanding are called for Redemption, then:

(i) the Notes to be redeemed will be selected by the Trustee as follows: (1) in the case of Global Notes, in accordance with the Depositary Procedures; and (2) in the case of Physical Notes, pro rata, by lot; and

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

(H)Payment of the Redemption Price. Without limiting the Company’s obligation to deposit the Redemption Price by the time proscribed bySection 3.01(B), the Company will cause the Redemption Price for a Note (or portion thereof) subject to Redemption to be paid to the Holder thereof on or before the later of (i) the applicable Redemption Date; and (ii) the date (x) such Note is delivered to the Paying Agent (in the case of a Physical Note) or (y) the Depositary Procedures relating to the Redemption, and the delivery to the Paying Agent, of such Holder’s beneficial interest in such Note to be redeemed are complied with (in the case of a Global Note). For the avoidance of doubt, interest payable pursuant to the proviso toSection 4.03(E) on any Note (or portion thereof) subject to Redemption must be paid pursuant to such proviso regardless of whether such Note is delivered or such Depositary Procedures are complied with pursuant to the first sentence of thisSection 4.03(H).

Article 5. CONVERSION

Section 5.01. RIGHTTO CONVERT.

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

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

(C)When Notes May Be Converted.

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

(1)Conversion upon Satisfaction of Common Stock Sale Price Condition. Prior to the Close of Business on the Business Day immediately preceding May 15, 2025, a Holder may convert its Notes during any calendar quarter commencing after the calendar quarter ending on December 31, 2018 (and only during such calendar quarter), if the Last Reported Sale Price per share of Common Stock for each of at least twenty (20) Trading Days (whether or not consecutive) during the period of thirty (30) consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter exceeds one hundred and thirty percent (130%) of the Conversion Price on the

- 27 -

applicable Trading Day.

(2)Conversion upon Satisfaction of Note Trading Price Condition. Prior to the Close of Business on the Business Day immediately preceding May 15, 2025, a Holder may convert its Notes during the five (5) consecutive Business Days immediately after any ten (10) consecutive Trading Day period (such ten (10) consecutive Trading Day period, the “Measurement Period”) if the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder in accordance with the procedures set forth below, for each Trading Day of the Measurement Period was less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. The condition set forth in the preceding sentence is referred to in the Indenture as the “Trading Price Condition.”

The Trading Price will be determined by the Bid Solicitation Agent pursuant to thisSection 5.01(C)(i)(2) and the definition of “Trading Price.” The Bid Solicitation Agent (if not the Company) will have no obligation to determine the Trading Price of the Notes unless the Company has requested such determination, and the Company will have no obligation to make such request (or seek bids itself) unless a Holder of at least five million dollars ($5,000,000) aggregate principal amount of Notes (or such lesser principal amount as may be then outstanding) provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock and the Conversion Rate. If such a Holder provides such evidence, then the Company will (if acting as Bid Solicitation Agent), or will instruct the Bid Solicitation Agent to, determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. If the Trading Price Condition has been met as set forth above, then the Company will notify the Holders, the Trustee and the Conversion Agent of the same, and each of the Holders, the Trustee and the Conversion Agent will be entitled to rely conclusively upon the accuracy of such notice and any calculations therein without independent verification. If, on any Trading Day after the Trading Price Condition has been met as set forth above, the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day, then the Company will notify the Holders, the Trustee and the Conversion Agent of the same, and, thereafter, neither the Company nor the Bid Solicitation Agent will be required to solicit bids again until another Holder request is made as provided above.

(3)Conversion upon Specified Corporate Events.

- 28 -

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

(I) distribute, to all or substantially all holders of Common Stock, any rights, options or warrants (other than rights issued pursuant to a stockholder rights plan, so long as such rights have not separated from the Common Stock and are not exercisable until the occurrence of a triggering event, except that such rights will be deemed to be distributed under this clause (I) upon their separation from the Common Stock or upon the occurrence of such triggering event) entitling them, for a period of not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced; or

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

then, in either case, (x) the Company will send notice of such distribution, and of the related right to convert Notes, to Holders, the Trustee and the Conversion Agent at least forty-five (45) Scheduled Trading Days before theEx-Dividend Date for such distribution (or, if later in the case of any such separation of rights issued pursuant to a stockholder rights plan or the occurrence of any such triggering event under a stockholder rights plan, as soon as reasonably practicable after the Company becomes aware of that such separation or triggering event has occurred or will occur); and (y) once the Company has sent such notice, Holders may convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately before suchEx-Dividend Date and the Company’s announcement that such distribution will not take place;provided,however, that Holders will not be entitled to convert their Notes pursuant to thisSection 5.01(C)(i)(3)(a) on account of any distribution if each Holder participates, at the same time and upon the same terms as holders of Common Stock and solely as a result of holding Notes, in such distribution without having to convert its Notes as if such Holder held a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for such distribution, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder as of such record

- 29 -

date.

(b)Certain Corporate Events. If, prior to the Close of Business on the Business Day immediately preceding May 15, 2025, a Fundamental Change, Make-Whole Fundamental Change or Common Stock Change Event (other than a Common Stock Change Event that is solely for the purpose of changing the Company’s jurisdiction of incorporation and that (x) does not constitute a Fundamental Change or a Make-Whole Fundamental Change and (y) results in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of common stock of the surviving entity and such common stock becomes the Reference Property for the Notes) occurs, then, in each case, Holders may convert their Notes at any time from, and including, the effective date of such transaction or event to, and including, the thirty fifth (35th) Trading Day after such effective date (or, if such transaction or event also constitutes a Fundamental Change (other than an Exempted Fundamental Change), to, but excluding, the related Fundamental Change Repurchase Date). No later than the second (2nd) Business Day after the effective date of any Fundamental Change, Make-Whole Fundamental Change or Common Stock Change Event that occurs before the Maturity Date, the Company will send notice to the Holders, the Trustee and the Conversion Agent of such transaction or event, such effective date and, if applicable, the related right to convert Notes.

(4)Conversion upon Redemption. If the Company calls any Note for Redemption, then the Holder of such Note may convert such Note at any time before the Close of Business on the Business Day immediately before the related Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such time as the Company pays such Redemption Price in full).

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

For the avoidance of doubt, the Notes may become convertible pursuant to any one or more of the precedingsub-paragraphs of thisSection 5.01(C)(i) and the Notes ceasing to be convertible pursuant to a particularsub-paragraph of thisSection 5.01(C)(i) will not preclude the Notes from being convertible pursuant to any othersub-paragraph of thisSection 5.01(C)(i).

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

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

- 30 -

(2) in no event may any Note be surrendered for conversion after the Close of Business on the Scheduled Trading Day immediately before the Maturity Date;

(3) if the Company calls any Note for Redemption pursuant toSection 4.03, then the Holder of such Note may not surrender such Note for conversion after the Close of Business on the Business Day immediately before the applicable Redemption Date, except to the extent the Company fails to pay the Redemption Price for such Note in accordance with the Indenture; and

(4) if a Fundamental Change Repurchase Notice is validly delivered pursuant toSection 4.02(F) with respect to any Note, then such Note may not be converted, except to the extent (a) such Note is not subject to such notice; or (b) such notice is withdrawn in accordance withSection 4.02(F).

Section 5.02. CONVERSION PROCEDURES.

(A)Generally.

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

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

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

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

(D)Interest Payable upon Conversion in Certain Circumstances. If the Conversion Date of a Note is after a Regular Record Date and before the next Interest Payment Date, then (i)

- 31 -

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

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

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

Section 5.03. SETTLEMENTUPON CONVERSION.

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

- 32 -

Section 5.03(B)(i)(2) (a “Cash Settlement”); or (z) a combination of cash and shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided inSection 5.03(B)(i)(3) (a “Combination Settlement”).

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

(i) subject toclause (iii) below, all conversions of Notes with a Conversion Date that occurs on or after May 15, 2025 will be settled using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders and the Conversion Agent no later than the Close of Business on the Scheduled Trading Day immediately before May 15, 2025;

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

(iii) if any Notes are called for Redemption, then (1) the Company will specify, in the related Redemption Notice sent pursuant toSection 4.03(F), the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the related Redemption Notice Date and before the Business Day immediately before the related Redemption Date; and (2) if such Redemption Date occurs on or after May 15, 2025, then such Settlement Method must be the same Settlement Method that, pursuant toclause (i) above, applies to all conversions of Notes with a Conversion Date that occurs on or after May 15, 2025;

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

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

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

(vii) the Settlement Method will be subject toSection 5.09(A)(2)

- 33 -

(B)Conversion Consideration.

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

(1) if Physical Settlement applies to such conversion, subject toSection 5.03(B)(ii), a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion;

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

(3) if Combination Settlement applies to such conversion, consideration consisting, subject toSection 5.03(B)(ii), of (a) a number of shares of Common Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such conversion; and (b) an amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation Period.

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

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

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

(C)Delivery of the Conversion Consideration. Except as set forth inSections

- 34 -

5.05(A),5.05(D) and5.09, the Company will pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder as follows: (i) if Cash Settlement or Combination Settlement applies to such conversion, on or before the second (2nd) Business Day immediately after the last VWAP Trading Day of such Observation Period; and (ii) if Physical Settlement applies to such conversion, on or before the second (2nd) Business Day immediately after such Conversion Date.

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

Section 5.04. RESERVEAND STATUSOF COMMON STOCK ISSUEDUPON CONVERSION.

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

(B)Status of Conversion Shares; Listing. Each Conversion Share, if any, delivered upon conversion of any Note will be duly and validly issued, fully paid,non-assessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder of such Note or the Person to whom such Conversion Share will be delivered). If the Common Stock is then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will cause each Conversion Share, when delivered upon conversion of any Note, to be admitted for listing on such exchange or quotation on such system.

Section 5.05. ADJUSTMENTSTOTHE CONVERSION RATE.

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

(i)Stock Dividends, Splits and Combinations. If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination of the Common Stock (in each case excluding an issuance solely pursuant to a Common Stock

- 35 -

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

LOGO

where:


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

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

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

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

Each adjustment to the Conversion Rate made pursuant to the preceding sentence will become effective at the time set forth in the definition ofCR₁ in thisSection 5.05(A)(i). If any dividend, distribution, stock split or stock combination of the type described in thisSection 5.05(A)(i) is declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been declared or announced.

- 36 -

(ii)Rights, Options and Warrants. If the Company distributes, to all or substantially all holders of Common Stock, rights, options or warrants (other than rights issued pursuant to a stockholder rights plan, to which the provisions set forth inSections 5.05(A)(iii)(1) and5.05(F) will apply) entitling such holders, for a period of not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion Rate will be increased based on the following formula:

LOGO


where:

CR₀	=	the Conversion Rate in effect immediately before the Open of Business on theEx-Dividend Date for such distribution;

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

OS	=	the number of shares of Common Stock outstanding immediately before the Open of Business on suchEx-Dividend Date;

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

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

Each adjustment to the Conversion Rate made pursuant to the preceding sentence will become effective at the time set forth in the definition ofCR₁ in thisSection 5.05(A)(ii).To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including as a result of such rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, option or warrants. To the extent such rights, options or warrants are not so distributed, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had theEx-Dividend Date for the distribution of such rights, options or warrants not occurred.

- 37 -

For purposes of thisSection 5.05(A)(ii) andSection 5.01(C)(i)(3)(a), in determining whether any rights, options or warrants entitle holders of Common Stock to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date of the distribution of such rights, options or warrants is announced, and in determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if not cash, to be determined by the Company in good faith.

(iii)Spin-Offs and Other Distributed Property.

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

(v) dividends, distributions, rights, options or warrants for which an adjustment to the Conversion Rate is required (or would be required without regard toSection 5.05(C)) pursuant toSection 5.05(A)(i) or5.05(A)(ii);

(w) dividends or distributions paid exclusively in cash for which an adjustment to the Conversion Rate is required (or would be required without regard toSection 5.05(C)) pursuant toSection 5.05(A)(iv);

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

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

(z) a distribution solely pursuant to a Common Stock Change Event, as to which the provisions set forth inSection 5.09 will apply,

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

LOGO


where:

CR₀	=	the Conversion Rate in effect immediately before the Open of

- 38 -


		Business on theEx-Dividend Date for such distribution;

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

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

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

Each adjustment to the Conversion Rate made pursuant to the preceding sentence will become effective at the time set forth in the definition ofCR₁ in thisSection 5.05(A)(iii)(1). IfFMV is equal to or greater thanSP, then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at the same time and on the same terms as holders of Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

To the extent such distribution is not so paid or made, or such rights, options or warrants are not exercised before their expiration (including as a result of being redeemed or terminated), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the distribution, if any, actually made or paid or on the basis of the distribution of only such rights, options or warrants, if any, that were actually exercised, if at all.

- 39 -

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

LOGO

where:


CR₀	=	the Conversion Rate in effect immediately before the Open of Business on theEx-Dividend Date for suchSpin-Off;

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

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

SP	=	the average of the Last Reported Sale Prices per share of Common Stock for each trading day in theSpin-Off Valuation Period.

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

- 40 -

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

(iv)Cash Dividends or Distributions. If any cash dividend or distribution is made to all or substantially all holders of Common Stock, then the Conversion Rate will be increased based on the following formula:

LOGO

where:


CR₀	=	the Conversion Rate in effect immediately before the Open of Business on theEx-Dividend Date for such dividend or distribution;

CR₁	=	the Conversion Rate in effect immediately after the Open of Business on suchEx-Dividend Date for such dividend or distribution;

SP	=	the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before suchEx-Dividend Date for such dividend or distribution;

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

Each adjustment to the Conversion Rate made pursuant to the preceding sentence will become effective at the time set forth in the definition ofCR₁ in thisSection 5.05(A)(iv). IfD is equal to or greater thanSP, then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution, at the same time and on the same terms as holders of Common Stock, the amount of cash that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

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

(v)Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock that is subject to the then-applicable tender offer rules under the

- 41 -

Exchange Act (other than anodd-lot tender offer that satisfies the requirements of Rule13e-4(h)(5), or any successor rule), and the value (determined as of the Expiration Time by the Company) of the cash and other consideration paid per share of Common Stock in such tender or exchange offer exceeds the average (such average, the “Reference Price”) of the Last Reported Sale Prices per share of Common Stock over the 10 consecutive Trading Day period (the “Tender/Exchange Offer Valuation Period”) beginning on, and including, the Trading Day immediately after the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased based on the following formula:

LOGO

where:


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

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

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

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

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

SP	=	the Reference Price per share of Common Stock;

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

- 42 -

settlement of such conversion until the second (2nd) Business Day after the last day of the Tender/Exchange Offer Valuation Period.

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

(B)No Adjustments in Certain Cases.

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

(ii)Certain Events. The Company will not be required to adjust the Conversion Rate except as provided inSection 5.05 orSection 5.07. Without limiting the foregoing, the Company will not be obligated to adjust the Conversion Rate on account of:

(1) except as otherwise provided inSection 5.05, the sale of shares of Common Stock for a purchase price that is less than the market price per share of Common Stock or less than the Conversion Price;

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

(3) the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit or incentive plan or program (including pursuant to any “evergreen” provision thereof) of, or assumed by, the Company or any of its Subsidiaries;

(4) the issuance of any shares of Common Stock pursuant to any

- 43 -

option, warrant, right or convertible, exercisable or exchangeable security of the Company outstanding as of the Issue Date;

(5) a third-party tender offer, other than a tender offer that is subject toSection 5.05(A)(v).

(6) the repurchase of any shares of Common Stock pursuant to an open market share purchase program or other buyback transaction, including structured or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives, or other buyback transaction, in each case that is not subject toSection 5.05(A)(v);

(7) a change in the par value (or lack of par value) of the Common Stock; or

(8) accrued and unpaid interest on the Notes.

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

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

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

(ii) the record date or effective date for any event that requires an adjustment to the Conversion Rate pursuant toSection 5.05(A)(i) to(iv), inclusive, has occurred on or before the Conversion Date for such conversion (in the case of Physical Settlement) or on or before any VWAP Trading Day in the Observation Period for such conversion (in the case of Combination Settlement), but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date or VWAP Trading Day, as applicable;

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

(iv) such shares are not entitled to participate in such event (because they were

- 44 -

not held on the related record date or otherwise),

then, solely for purposes of such conversion, the Company will, without duplication, give effect to such adjustment on such Conversion Date (in the case of Physical Settlement) or such VWAP Trading Day (in the case of Combination Settlement), and, for the avoidance of doubt, such shares will not be entitled to participate in such event. In such case, if the date on which the Company is otherwise required to deliver the consideration due upon such conversion is before the first date on which the amount of such adjustment can be determined, then the Company will delay the settlement of such conversion until the second (2nd) Business Day after such first date.

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

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

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

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

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

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

then (x) such Conversion Rate adjustment will not be given effect for such conversion (in the case of Physical Settlement) or for such VWAP Trading Day (in the case of Combination Settlement); and (y) the shares of Common Stock, if any, issuable upon such conversion (in the case of Physical Settlement) or issuable with respect to such VWAP Trading Day (in the case of Combination Settlement) based on such unadjusted Conversion Rate will be entitled to participate in such dividend or distribution.

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

- 45 -

referred to in such Section to all holders of the Common Stock, subject to readjustment in accordance with such Section if such rights expire, terminate or are redeemed.

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

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

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

(J)Calculations. All calculations with respect to the Conversion Rate and adjustments thereto will be made to the nearest cent (with 0.5 of a cent rounded upward) or to the nearest 1/10,000th of a share of Common Stock (with 5/100,000ths rounded upward), as applicable.

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

Section 5.06. VOLUNTARY ADJUSTMENTS.

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

- 46 -

(B)Notice of Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant to thisSection 5.06, then, on or before the effective date of such increase, the Company will send notice to the Trustee and each Holder of such increase, the amount thereof and the period during which such increase will be in effect.

Section 5.07. ADJUSTMENTSTOTHE CONVERSION RATEIN CONNECTIONWITHA MAKE-WHOLE FUNDAMENTAL CHANGE.

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


	Stock Price

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

(i) if such Stock Price is between two Stock Prices in the table above or the effective date is between two effective dates in the table above, then the number of Additional Shares will be determined by a straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices in the table and the earlier and later effective dates in the table above, as applicable, based on a365- or366-day year, as applicable; and

(ii) if the Stock Price is greater than $200.00 (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above are adjusted pursuant toSection 5.07(B)), or less than $28.74 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the Conversion Rate.

Notwithstanding anything to the contrary in the Indenture or the Notes, in no event will the Conversion Rate be increased to an amount that exceeds 34.7947 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is required to be adjusted pursuant toSection 5.05(A).

(B)Adjustment of Stock Prices and Additional Shares. The Stock Prices in the first row (i.e., the column headers) of the table set forth inSection 5.07(A) will be adjusted at the same time and for the same events for which, the Conversion Rate is adjusted as a result of the operation ofSection 5.05(A). The adjusted Stock Prices will equal the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate

- 47 -

immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The numbers of Additional Shares in the table set forth inSection 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Rate is adjusted pursuant toSection 5.07(A).

(C)Notice of the Occurrence of a Make-Whole Fundamental Change. The Company will notify the Holders, the Trustee and the Conversion Agent of each Make-Whole Fundamental Change no later than the second (2nd) Business Day after the effective date of such Make-Whole Fundamental Change.

(D)Settlement of Cash Make-Whole Fundamental Changes. For the avoidance of doubt, if holders of Common Stock receive solely cash in a Make-Whole Fundamental Change, then, pursuant toSection 5.09, conversions of Notes will thereafter be settled no later than the third (3rd) Business Day after the relevant Conversion Date.

Section 5.08. EXCHANGEIN LIEUOF CONVERSION.

When a Holder surrenders any Note for conversion, the Company may, at its election (an “Exchange Election”), direct the Conversion Agent to surrender, on or prior to the Business Day immediately following the Conversion Date, such Note to one or more financial institutions designated by the Company for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution(s) must agree to timely pay or deliver, as the case may be, in exchange for such Note, the Conversion Consideration that would otherwise be due pursuant to thisArticle 5. To make an Exchange Election with respect to any Note, the Company must, by the Close of Business on the Business Day following the relevant Conversion Date, notify in writing the Trustee, the Conversion Agent (if other than the Trustee) and the Holder of such Note and the Company must notify the designated financial institution(s) of the relevant deadline for delivery of the Conversion Consideration and the type of Conversion Consideration to be paid or delivered, as the case may be.

Any Notes exchanged by the designated financial institution(s) will remain outstanding, subject to the Depositary Procedures, if applicable. If any financial institution agrees to accept any Notes for exchange but does not timely pay or deliver, as the case may be, the related Conversion Consideration, or if such designated financial institution does not accept the Notes for exchange, then the Company will pay or deliver, as the case may be, the relevant Conversion Consideration, as, and at the time, required pursuant to the Indenture as if the Company had not made the exchange election.

The Company’s designation of any financial institution(s) to which the Notes may be submitted for exchange does not require such financial institution(s) to accept any Notes.

Section 5.09. EFFECTOF COMMON STOCK CHANGE EVENT.

(A)Generally. If there occurs any:

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

- 48 -

Stock, (y) a change only in par value or from par value to no par value or no par value to par value and (z) stock splits and stock combinations that do not involve the issuance of any other series or class of securities);

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

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

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

(1) from and after the effective time of such Common Stock Change Event, (I) the Conversion Consideration due upon conversion of any Note and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in thisArticle 5 (or in any related definitions) were instead a reference to the same number of Reference Property Units; (II) for purposes ofSection 4.03, each reference to any number of shares of Common Stock in such Section (or in any related definitions) will instead be deemed to be a reference to the same number of Reference Property Units; and (III) for purposes of the definition of “Fundamental Change” and “Make-Whole Fundamental Change,” (x) the terms “Common Stock” and “common equity” will be deemed to mean the common equity (which term will be deemed to include depositary receipts or shares representing common equity), if any, forming part of such Reference Property; and (y) references to the Company will be deemed to be references to the entity that is the issuer of such common equity;

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

(3) for these purposes, the Daily VWAP or Last Reported Sale Price of any Reference Property Unit or portion thereof that does not consist of a class of securities will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof).

If the Reference Property consists of more than a single type of consideration to be

- 49 -

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

At or before the effective time of such Common Stock Change Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a supplemental indenture pursuant toSection 8.01(F), which supplemental indenture will give effect to the provisions of thisSection 5.09(A) and contain such other provisions as the Company reasonably determines are appropriate to preserve the economic interests of the Holders. If such Reference Property includes, in whole or in part, any stock or other securities, then such supplemental indenture will, to the extent applicable, provide for subsequent adjustments to the Conversion Rate in a manner consistent withSection 5.05. In addition, if the Reference Property includes, in whole or in part, shares of stock or other securities or assets (other than cash or cash equivalents) of a Person other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain such additional provisions the Company reasonably determines are appropriate to preserve the economic interests of the Holders.

(B)Notice of Common Stock Change Events. No later than the second (2nd) Business Day after the effective date of each Common Stock Change Event, the Company will notify the Holders and the Trustee of such Common Stock Change Event, including a brief description of such Common Stock Change Event, its effective date and a brief description of the anticipated change in the conversion right of the Notes.

(C)Compliance Covenant. The Company will not become a party to any Common Stock Change Event unless its terms are consistent with thisSection 5.09.

Article 6. SUCCESSORS

ThisArticle 6will apply to the Notes in lieu of Article 10 of the Base Indenture, which will be deemed to be replaced with thisArticle 6,mutatis mutandis.

Section 6.01. WHENTHE COMPANY MAY MERGE, ETC.

(A)Generally. The Company will not consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to another Person (other than any such sale, lease or transfer to one or more of the Company’s Wholly Owned Subsidiaries not effected by means of a consolidation or merger) (a “Business Combination Event”), unless:

(i) the resulting, surviving or transferee Person either (x) is the Company or (y) if not the Company, is a corporation (the “Successor Corporation”) duly organized and existing under the laws of the United States of America, any State thereof or the District of Columbia that expressly assumes (by executing and delivering to the Trustee,

- 50 -

at or before the effective time of such Business Combination Event, a supplemental indenture pursuant toSection 8.01(E)) all of the Company’s obligations under the Indenture and the Notes; and

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

Section 6.02. SUCCESSOR CORPORATION SUBSTITUTED.

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

Article 7. DEFAULTS AND REMEDIES

ThisArticle 7will apply to the Notes in lieu of Article 6 of the Base Indenture, which will be deemed to be replaced with thisArticle 7,mutatis mutandis.

Section 7.01. EVENTSOF DEFAULT.

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

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

- 51 -

state that the such notice is a “Notice of Default”;

(vii) a default by the Company or any of its Significant Subsidiaries with respect to any one or more mortgages, agreements or other instruments under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed of at least thirty million dollars ($30,000,000) (or its foreign currency equivalent) in the aggregate of the Company or any of its Significant Subsidiaries, whether such indebtedness exists as of the Issue Date or is thereafter created, where such default:

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

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

and, in either case, such Acceleration has not been rescinded or annulled or such failure to pay or default is not cured or waived, or such indebtedness is not paid or discharged in full, within sixty (60) days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding;

(viii) one or more final judgments being rendered against the Company or any of its Significant Subsidiaries for the payment of at least thirty million dollars ($30,000,000) (or its foreign currency equivalent) in the aggregate (excluding any amounts covered by insurance), where such judgment is not discharged or stayed within sixty (60) days after (i) the date on which the right to appeal the same has expired, if no such appeal has commenced; or (ii) the date on which all rights to appeal have been extinguished; and

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

(1) commences a voluntary case or proceeding;

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

Section 7.02. ACCELERATION.

(A)Automatic Acceleration in Certain Circumstances. If an Event of Default set forth inSection 7.01(A)(ix) or7.01(A)(x) occurs with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company), then the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any Person.

(B)Optional Acceleration. Subject toSection 7.03, if an Event of Default (other than an Event of Default set forth inSection 7.01(A)(ix) or7.01(A)(x) with respect to the Company and not solely with respect to a Significant Subsidiary of the Company) occurs and is continuing, then the Trustee, by notice to the Company, or Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding to become due and payable immediately.

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

- 53 -

any subsequent Default or impair any right consequent thereto.

Section 7.03. SOLE REMEDYFORA FAILURETO REPORT.

(A)Generally. Notwithstanding anything to the contrary in the Indenture or the Notes, the Company may elect that the sole remedy for any Event of Default (a “Reporting Event of Default”) pursuant toSection 7.01(A)(vi) arising from the Company’s failure to comply withSection 3.02 (including the Company’s obligations under Section 314(a)(1) of the Trust Indenture Act) will, for each of the first three hundred and sixty (360) calendar days on which a Reporting Event of Default has occurred and is continuing, consist exclusively of the accrual of Special Interest on the Notes. If the Company has made such an election, then (i) the Notes will be subject to acceleration pursuant toSection 7.02 on account of the relevant Reporting Event of Default from, and including, the three hundred and sixty first (361st) calendar day on which a Reporting Event of Default has occurred and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when due; and (ii) Special Interest will cease to accrue on any Notes from, and including, the earlier of (x) the date such Event of Default is cured or waived and (y) such three hundred and sixty first (361st) calendar day (it being understood that interest on any defaulted Special Interest will nonetheless accrue pursuant toSection 2.04(B)).

(B)Amount and Payment of Special Interest. Any Special Interest that accrues on a Note pursuant toSection 7.03(A) will be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate per annum equal to one quarter of one percent (0.25%) of the principal amount thereof for the first one hundred and eighty (180) days on which Special Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof from the one hundred eighty first (181st) day to, and including, the three hundred sixtieth (360th) day on which Special Interest accrues;provided,however, that in no event will Special Interest accrue on any day on a Note at a rate per annum that exceeds one half of one percent (0.50%), regardless of the number of events or circumstances giving rise to the accrual of Special Interest. For the avoidance of doubt, any Special Interest that accrues on a Note will be in addition to the Stated Interest that accrues on such Note.

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

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

- 54 -

Section 7.04. OTHER REMEDIES.

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

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

Section 7.05. WAIVEROF PAST DEFAULTS.

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

Section 7.06. CONTROLBY MAJORITY.

Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law, the Indenture or the Notes, or that, subject to Section 7.01 of the Base Indenture, the Trustee determines may be unduly prejudicial to the rights of other Holders or may involve the Trustee in liability, unless the Trustee is offered security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such direction.

Section 7.07. LIMITATIONON SUITS.

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

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

(B) Holders of at least twenty five percent (25%) in aggregate principal amount of the

- 55 -

Notes then outstanding deliver a written request to the Trustee to pursue such remedy;

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

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

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

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

Section 7.08. ABSOLUTE RIGHTOF HOLDERSTO INSTITUTE SUITFORTHE ENFORCEMENTOFTHE RIGHTTO RECEIVE PAYMENTAND CONVERSION CONSIDERATION.

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

Section 7.09. COLLECTION SUITBY TRUSTEE.

The Trustee will have the right, upon the occurrence and continuance of an Event of Default pursuant toclause(i),(ii) or(iv) ofSection 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for the total unpaid or undelivered principal of, or Redemption Price or Fundamental Change Repurchase Price for, or interest on, or Conversion Consideration due pursuant toArticle 5 upon conversion of, the Notes, as applicable, and, to the extent lawful, any Default Interest on any Defaulted Amounts, and such further amounts sufficient to cover the costs and expenses of collection, including all amounts owed to it under Section 7.06 of the Base Indenture.

Section 7.10. TRUSTEE MAY FILE PROOFSOF CLAIM.

The Trustee has the right to (A) file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes) or its creditors or property and (B) collect, receive and distribute any money or other property payable or deliverable on any such claims. Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee consents to the

- 56 -

making of such payments directly to the Holders, to pay to the Trustee any amount due to the Trustee for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to the Trustee pursuant to Section 7.06 of the Base Indenture. To the extent that the payment of any such compensation, expenses, disbursements, advances and other amounts out of the estate in such proceeding, is denied for any reason, payment of the same will be secured by a lien on, and will be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding (whether in liquidation or under any plan of reorganization or arrangement or otherwise). Nothing in the Indenture will be deemed to authorize the Trustee to authorize, consent to, accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 7.11. PRIORITIES.

The Trustee will pay or deliver in the following order any money or other property that it collects pursuant to thisArticle 7:

First: to the Trustee and any Note Agent and their respective agents and attorneys for amounts due hereunder, including payment of all fees, compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

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

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

The Trustee may fix a record date and payment date for any payment or delivery to the Holders pursuant to thisSection 7.11, in which case the Trustee will instruct the Company to, and the Company will, deliver, at least fifteen (15) calendar days before such record date, to each Holder and the Trustee a notice stating such record date, such payment date and the amount of such payment or nature of such delivery, as applicable.

Section 7.12. UNDERTAKINGFOR COSTS.

In any suit for the enforcement of any right or remedy under the Indenture or the Notes or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking to pay the costs of such suit, and (B) assess reasonable costs (including reasonable attorneys’ fees) against any litigant party in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant party;provided,however, that thisSection 7.12 does not apply to any suit by the Trustee, any suit by a Holder pursuant toSection 7.08 or any suit by

- 57 -

one or more Holders of more than ten percent (10%) in aggregate principal amount of the Notes then outstanding.

Article 8. AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 8.01 andSection 8.02 will apply to the Notes in lieu of Section 9.01 and Section 9.02, respectively, of the Base Indenture, which will be deemed to be replaced withSection 8.01 andSection 8.02, respectively,mutatis mutandis.

Section 8.01. WITHOUTTHE CONSENTOF HOLDERS.

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

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

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

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

(N) comply with the rules of the Depositary for the Notes in a manner that does not adversely affect the rights of any Holder; or

Section 8.02. WITHTHE CONSENTOF HOLDERS.

(A)Generally. Subject toSections 8.01,7.05 and7.08 and the immediately following sentence, the Company and the Trustee may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, amend or supplement the Indenture or the Notes or waive compliance with any provision of the Indenture or the Notes. Notwithstanding anything to the contrary in the foregoing sentence, without the consent of each affected Holder, no amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may:

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

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

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

(iv) make any change that adversely affects the conversion rights of any Note;

(v) impair the absolute rights of any Holder set forth inSection 7.08 (as such section is in effect on the Issue Date);

(vi) change the ranking of the Notes;

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

(viii) reduce the amount of Notes whose Holders must consent to any

- 59 -

amendment, supplement, waiver or other modification; or

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

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

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

Section 8.03. NOTICEOF AMENDMENTS, SUPPLEMENTSAND WAIVERS.

Promptly after any amendment, supplement or waiver pursuant toSection 8.01 or8.02 becomes effective, the Company will send to the Holders and the Trustee notice that (A) describes the substance of such amendment, supplement or waiver in reasonable detail and (B) states the effective date thereof. The failure to send, or the existence of any defect in, such notice will not impair or affect the validity of such amendment, supplement or waiver.

Section 8.04. NOTATIONSAND EXCHANGES.

If any amendment, supplement or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion, require the Holder of such Note to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company on such Note and return such Note to such Holder. Alternatively, at its discretion, the Company may, in exchange for such Note, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.04 of the Base Indenture, a new Note that reflects the changed terms. The failure to make any appropriate notation or issue a new Note pursuant to thisSection 8.04 will not impair or affect the validity of such amendment, supplement or waiver.

Article 9. SATISFACTION AND DISCHARGE

ThisArticle 9will apply to the Notes in lieu of Article 11 of the Base Indenture, which will be deemed to be replaced with thisArticle 9,mutatis mutandis.

- 60 -

Section 9.01. TERMINATIONOF COMPANY’S OBLIGATIONS.

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

(A) all Notes then outstanding (other than Notes replaced pursuant toSection 2.07 of the Base Indenture) have (A) been delivered to the Trustee for cancellation; or (B) become due and payable (whether on a Redemption Date, a Fundamental Change Repurchase Date, the Maturity Date, upon conversion or otherwise) for an amount of cash or Conversion Consideration, as applicable, that has been fixed;

(B) the Company has caused there to be irrevocably deposited with the Trustee, or with the Paying Agent (or, with respect to Conversion Consideration, the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered to the Holders, cash (or, with respect to Notes to be converted, Conversion Consideration) sufficient to satisfy all amounts or other property due on all Notes then outstanding (other than Notes replaced pursuant to Section 2.07 of the Base Indenture);

At the Company’s request, upon the Company’s delivery to the Trustee of an Officer’s Certificate and an Opinion of Counsel, each stating that the conditions precedent to the discharge of the Indenture have been satisfied, the Trustee will acknowledge the satisfaction and discharge of the Indenture.

Section 9.02. REPAYMENTTO COMPANY.

Subject to applicable unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will promptly notify the Company if there exists (and, at the Company’s request, promptly deliver to the Company) any cash, Conversion Consideration or other property held by any of them for payment or delivery on the Notes that remain unclaimed two (2) years after the date on which such payment or delivery was due. After such delivery to the Company, the Trustee, the Paying Agent and the Conversion Agent will have no further liability to any Holder with respect to such cash, Conversion Consideration or other property, and Holders entitled to the payment or delivery of such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor of the Company.

Section 9.03. REINSTATEMENT.

If the Trustee, the Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it pursuant toSection 9.01 because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains or

- 61 -

otherwise prohibits such application, then the discharge of the Indenture pursuant toSection 9.01 will be rescinded;provided,however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to the Holders thereof, then the Company will be subrogated to the rights of such Holders to receive such cash or other property from the cash or other property, if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable.
