SECTION 2.04.Execution and Authentication. One Officer shall sign the Notes for the Company by manual or facsimile signature. If an Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless.

A Note shall not be valid until an authorized signatory of the Trustee manually authenticates the Note. Upon the written order of the Company signed by an Officer, the Trustee shall authenticate a Note executed by the Company. The signature of the Trustee on the Note shall be conclusive evidence that the Note has been duly and validly authenticated under this Indenture.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Responsible Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.05.Registrar and Paying Agent. The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Notes may be presented for payment (the “Paying Agent”). The Corporate Trust Office shall be considered as one such office or agency of the Company for each of the aforesaid purposes. The Registrar shall keep a register of the Notes (the “Register”) and of their transfer and exchange. The Company may have one or moreco-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent, and the term “Registrar” includes anyco-registrars.

The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any of its Wholly Owned Subsidiaries that is not a Foreign Subsidiary may act as Paying Agent or Registrar.

The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee;provided,however, that no such removal shall become effective until (1) acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (2) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (1) above. The Registrar or Paying Agent may resign at any time upon written notice;provided,however, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.08.

Prior to 10:00 a.m., New York City time, on the Maturity Date, each Interest Payment Date, any Fundamental Change Repurchase Date and any settlement date of a Conversion Obligation, the Company shall deposit with the Paying Agent (or if the Company or a Wholly Owned Subsidiary of the Company is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such amounts owed on such dates. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of amounts owed on such dates and shall notify the Trustee of any Default by the Company in making any such payment. If the Company or a Wholly Owned Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.07.Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with Section 312(a) of the Trust Indenture Act.

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

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

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

No service charge shall be made to any holder for any registration of, transfer or exchange of Notes, but the Company or the Trustee may require payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

Neither the Company nor the Trustee nor any Registrar shall be required to exchange, issue or register a transfer of (a) any Note or portions thereof surrendered for conversion pursuant to Article 10 or (b) any Note or portions thereof tendered for repurchase (and not withdrawn) pursuant to Article 3.

(i) Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian for the Global Notes therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture.

(ii) Notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless:

(A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Note and a successor Depositary has not been appointed within 60 days;

(B) the Depositary has ceased to be registered as a clearing agency under the Exchange Act and a successor Depositary has not been appointed within 60 days; or

(C) an Event of Default with respect to the Notes has occurred and is continuing and such beneficial owner requests that its Notes be issued in physical, certificated form.

(iii) In addition, certificated Notes shall be issued in exchange for beneficial interests in a Global Note upon request by or on behalf of the Depositary in accordance with customary procedures following the request of a beneficial owner seeking to enforce its rights under the Notes or this Indenture, including its rights following the occurrence of an Event of Default.

(iv) Notes issued in exchange for a Global Note or for any portion of a Global Note pursuant to clause (ii) or (iii) above shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Notes or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Notes to be exchanged shall be surrendered by the Depositary to the Trustee, as Registrar;provided that pending completion of the exchange of a Global Note, the Trustee acting as custodian for the Global Notes for the Depositary or its nominee with respect to such Global Notes, shall reduce the principal amount thereof, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the books and records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Notes issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

(v) In the event of the occurrence of any of the events specified in clause (ii) above or upon any request described in clause (iii) above, the Company shall promptly make available to the Trustee a sufficient supply of certificated Notes in definitive, fully registered form, without interest coupons.

(vi) Neither any members of, or participants in, the Depositary (the “Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Notes registered in the name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Notes.

(vii) At such time as all interests in a Global Note have been repurchased, converted, cancelled or exchanged for Notes in certificated form, such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the custodian for the Global Note. At any time prior to such cancellation, if any interest in a Global Note is repurchased, converted, cancelled or exchanged for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the custodian for the Global Note, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the custodian for the Global Note, at the direction of the Trustee, to reflect such reduction.

As used in this Section 2.08(c), the term “transfer” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein.

(d) Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the last date of the original issuance of the Notes, or such shorter period of time as permitted by Rule 144 under the Securities Act or any successor provision thereunder, and (2) such later date, if any, as may be required by applicable laws, any certificate evidencing a Restricted Security shall bear the Restricted Note Legend (or in the case of Common Stock issued upon conversion of the Notes, the Restricted Common Stock Legend), unless such Restricted Security has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or sold pursuant to Rule 144 under the Securities Act or any similar provision then in force, or unless otherwise agreed by the Company in writing as set forth above, with written notice thereof to the Trustee. If, prior to the Resale Restriction Termination Date, an Affiliate of the Company beneficially owns an interest in a Global Note, the Company may require such Person to hold its interest in the Notes in certificated form bearing the Restricted Notes Legend and a restricted CUSIP number.

(e) In connection with any transfer of the Notes prior to the Resale Restriction Termination Date, the holder must complete and deliver the form of assignment set forth on the certificate representing the Note, with the appropriate box checked, to the Trustee (or any successor Trustee, as applicable).

Any Notes that are Restricted Securities and as to which such restrictions on transfer shall have expired in accordance with their terms or as to conditions for removal of the Restricted Note Legend set forth therein have been satisfied may, upon surrender of such Notes for exchange to the Registrar in accordance with the provisions of this Section 2.08, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by Section 2.08(c). If such Restricted Security surrendered for exchange is represented by a Global Note bearing the Restricted Note Legend, the principal amount of the legended Global Notes shall be reduced by the appropriate principal amount and the principal amount of a Global Note without a Restricted Note Legend shall be increased by an equal principal amount. If a Global Note without the Restricted Note Legend is not then outstanding, the Company shall execute and the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary. The Company shall notify the Trustee in writing upon the occurrence of the Resale Restriction Termination Date and, if applicable, promptly after a registration statement with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

Any Common Stock issued upon conversion of the Notes as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the Restricted Common Stock Legend.

(f) The Trustee shall have no responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the holders of Notes and all payments to be made to holders of Notes under the Notes shall be given or made only to or upon the order of the registered holders of Notes (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Notes shall be exercised only through the Depositary subject to the customary procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members.

(g) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Notes (including any transfers between or among Agent Members) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

SECTION 2.09.Replacement Notes. If a mutilated Note is surrendered to the Registrar or if the Holder claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the Holder takes the following actions and satisfies the requirements ofSection 8-405 of the Uniform Commercial Code:

(i) notifies the Company or the Trustee within a reasonable time after he has notice of such loss, destruction or wrongful taking and prior to the Registrar registering a transfer of such Note;

(ii) makes a request to the Company or the Trustee for a replacement Note prior to the Note being acquired by a protected purchaser as defined inSection 8-303 of the Uniform Commercial Code (a “protected purchaser”); and

(iii) satisfies any other reasonable requirements of the Trustee.

If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Trustee to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss, expense, claim or liability that any of them may suffer if a Note is replaced and subsequently presented or claimed for payment. The Company and the Trustee may charge the Holder for their expenses in replacing a Note. In case any Note which has matured or is about to mature or has been validly tendered for repurchase on a Fundamental Change Repurchase Date (and not validly withdrawn), or is to be converted, shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence to their satisfaction of the destruction, loss or theft of such Notes and of the ownership thereof.

Every replacement Note is an additional obligation of the Company.

The provisions of this Section 2.09 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes.

SECTION 2.10.Outstanding Notes. Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

If a Note is replaced pursuant to Section 2.09, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a protected purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a Fundamental Change Repurchase Date or Maturity Date money sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions thereof) to be repurchased or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company shall be considered as though not outstanding; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver of consent, only Notes that the Trustee actually knows are so owned shall be so disregarded. The Company agrees to notify the Trustee of the existence of any Notes owned by the Company.

SECTION 2.11.Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Notes shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and delivered hereunder.

SECTION 2.12.Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange, payment or conversion. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, conversion or cancellation in accordance with its customary procedures. The Company may not issue new Notes to replace Notes it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 10.

The Company may, to the extent permitted by law, repurchase any Notes in the open market or by tender offer at any price or by private agreement. The Company may, at its option, surrender any Notes repurchased by it to the Trustee for cancellation, but may not reissue or resell such Notes. Any Notes surrendered to the Trustee for cancellation may not be reissued or resold and shall be promptly cancelled.

SECTION 2.13.Defaulted Interest. Any interest on any Note which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 calendar days, shall forthwith cease to be payable to the Holder on the Regular Record Date, and such defaulted interest and interest (to the extent lawful) on such defaulted interest at the annual rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Company at its election, in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at 5:00 p.m., New York City time, on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date (not less than 30 calendar days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest which shall be not more than fifteen calendar days and not less than ten calendar days prior to the Special Interest Payment Date and not less than ten calendar days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the Company, shall promptly cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given to each Holder, not less than ten calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at 5:00 p.m., New York City time, on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

(b) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

(xiii) the CUSIP number or numbers, as the case may be, of the Notes; and

(d) Free Transferability Additional Interest payable in accordance with Section 4.13(c) shall be payable in arrears on each Interest Payment Date following the 380th day after the last date of original issuance of the Notes in the same manner as regular interest on the Notes.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

SECTION 6.05.Waiver of Past Defaults. Subject to Section 6.02, the Holders of a majority in aggregate principal amount of the Notes outstanding may, on behalf of all Holders of all the Notes, waive any past Default or Event of Default under this Indenture and its consequences, except:

(i) the Company’s failure to pay principal of or interest on any Notes when due;

(ii) the Company’s failure to convert any Notes into cash and, if applicable, Common Stock pursuant to the terms of this Indenture;

(iii) the Company’s failure to pay the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date in connection with a Holder exercising its repurchase rights; or

(iv) the Company’s failure to comply with any of the provisions of this Indenture that under Section 9.02 cannot be amended without the consent of each Holder affected.

When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.06.Control by Majority. The Holders of a majority in aggregate principal amount of the outstanding Notes shall have the right to direct the time, method and place of any proceedings for any remedy available to the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability or expense for which the Trustee has not received adequate indemnity as determined by it in good faith;provided,however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnity or security reasonably satisfactory to it in its sole discretion against all losses, liabilities, and expenses caused by taking or not taking such action.

SECTION 6.07.Limitation on Suits. Except to enforce the right to receive payment of principal or interest when due or consideration due upon conversion when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

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

(b) the Holders of at least 25% in aggregate principal amount of the outstanding Notes have made a written request to the Trustee to pursue the remedy, and offered reasonable security or indemnity against any costs, liability or expense of the Trustee;

(c) the Trustee fails to comply with such request within 60 calendar days after receipt of such request and the offer of indemnity; and

(d) the Trustee has not received an inconsistent direction from the Holders of a majority in aggregate principal amount of the outstanding Notes.

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

SECTION 6.08.Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal (including payments pursuant to the required repurchase provisions of the Notes) of and interest on the Notes held by such Holder, on or after the respective due dates expressed in the Notes or in the event of repurchase, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. In addition, notwithstanding any other provision of this Indenture, the right of any Holder to enforce its rights of conversion in accordance with the provisions of Article 10, on or after the applicable date for settlement of the Company’s Conversion Obligation, shall not be impaired or affected without the consent of such Holder.

SECTION 6.09.Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a), (b) or (c) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07.

SECTION 6.10.Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel) and the Holders allowed in any judicial proceedings relative to the Company, its Subsidiaries or its or their respective creditors or property and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter, and may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07.

SECTION 6.11.Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

FIRST: to the Trustee for amounts due under Section 7.07;

SECOND: to Holders for amounts due and unpaid on the Notes for principal (including payments pursuant to the required repurchase provisions of the Notes) and interest, ratably without preference or priority of any kind, according to the amounts due and payable on the Notes for principal (including payments pursuant to the required repurchase provisions of the Notes) and interest or in respect of any Conversion Obligation of the Company, respectively; and

THIRD: to the Company.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.11. At least fifteen calendar days before such record date, the Trustee shall send to each Holder and the Company a notice that states the record date, the payment date and amount to be paid.

SECTION 6.12.Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.12 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.08 or a suit by Holders of more than 10% in principal amount of the Notes.

SECTION 6.13.Failure to Comply with Reporting Covenant(a) . Notwithstanding anything to the contrary in this Indenture, the Company may elect that the sole remedy for an Event of Default relating to the Company’s failure to comply with the covenant in Section 4.03(a) and the Company’s failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act (which also relate to the provision of reports), for the 360 days after the occurrence of such an Event of Default shall consist exclusively of the right to receive additional interest (the “Reporting Additional Interest”) on the Notes at an annual rate equal to (i) 0.25% of the outstanding principal amount of the Notes from the first date of the occurrence of such Event of Default to, but not including, the 180^th day thereafter (or such earlier date on which the Event of Default relating to the Company’s reporting obligations pursuant to Section 4.03(a) and Section 314(a)(1) of the Trust Indenture Act shall have been cured or waived) and (ii) 0.50% of the outstanding principal amount of the Notes from the 181^st date following the occurrence to the 360^th day after the first date of the occurrence of such Event of Default (or such earlier date on which the Event of Default relating to the Company’s reporting obligations pursuant to Section 4.03(a) and Section 314(a)(1) of the Trust Indenture Act shall have been cured or waived). In the event the Company does not elect to pay the Reporting Additional Interest upon an Event of Default in accordance with this Section 6.13, the Notes shall be subject to acceleration pursuant to Section 6.02. This Reporting Additional Interest shall be payable in arrears on the same dates and in the same manner as regular interest on the Notes. On such 360^th day, if such Event of Default is continuing, such Reporting Additional Interest shall cease to accrue and the Notes shall be subject to acceleration as provided in Section 6.02. For the avoidance of doubt, in the event Rule 144 Additional Interest is triggered under Section 4.12 or Free Transferability Additional Interest is triggered under Section 4.13 during a period in which the Company has elected that the accrual of Reporting Additional Interest be the sole remedy for any such Event of Default, no Reporting Additional Interest shall be payable pursuant to this Section 6.13 for so long as Rule 144 Additional Interest is accruing and payable pursuant to Section 4.12 or Free

Transferability Additional Interest is accruing and payable pursuant to Section 4.13. This Section 6.13 shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. The Company shall notify the Trustee in writing promptly upon its becoming aware of its obligation to pay Reporting Additional Interest, the date on which such Reporting Additional Interest is payable and the amount identified as Reporting Additional Interest. In no event shall the Trustee be charged with knowledge of whether such Reporting Additional Interest is due, unless it has received the written notice referred to in the preceding sentence.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred therein or thereby.

SECTION 7.03.Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Conversion Agent, Paying Agent, Registrar orco-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04.Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication.

SECTION 7.05.Notice of Defaults. (a) The Trustee shall not be deemed to have notice or knowledge of any Default, unless a Responsible Officer has received written notice thereof at its Corporate Trust Office, and such notice references this Indenture. No duty imposed upon the Trustee in this Indenture shall be applicable with respect to any Default of which the Trustee is not deemed to have notice.

(b) If a Default or Event of Default occurs and is continuing, the Trustee shall deliver to each Holder at the address set forth in the Register notice of the Default or Event of Default within 90 calendar days after receipt by it of written notice of the occurrence of such Default or Event of Default. Except in the case of a Default or Event of Default in payment of principal or interest on any Notes or a Default in the failure to deliver the consideration due upon conversion, the Trustee may withhold notice if and so long as a committee of its Responsible Officers in good faith determines that withholding notice is in the interests of the Holders.

SECTION 7.06.Reports by Trustee to Holders. As promptly as practicable after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such May 15 that complies with Section 313(a) of the Trust Indenture Act, if required by such Section 313(a) of the Trust Indenture Act. The Trustee also shall comply with Section 313(b) of the Trust Indenture Act. The Trustee shall also transmit all reports required by Section 313(c) of the Trust Indenture Act.

SECTION 7.07.Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonableout-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee, and hold it harmless, against any and all loss, liability or expense (including reasonable attorneys’ fees) incurred by or in connection with the offer and sale of the Notes or the administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof;provided,however, that any failure so to notify the Company shall not relieve the Company of its indemnity obligations hereunder. The Company shall defend the claim and the indemnified party shall provide reasonable cooperation at the Company’s expense in the defense. Such indemnified parties may have separate counsel and the Company shall pay the fees and expenses of such counsel;provided,however, that the Company shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no conflict of interest between the Company and such parties in connection with such defense. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct and negligence.

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest and any liquidated damages on particular Notes.

The Company’s payment obligations pursuant to this Section shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of an Event of Default specified in Section 6.01(j) or (k) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

SECTION 7.08.Replacement of Trustee. The Trustee may resign by giving 30 days written notice to the Company. The Holders of a majority in principal amount of the Notes may remove the Trustee by giving 30 days written notice to the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if:

(a) the Trustee fails to comply with Section 7.10;

(b) the Trustee is adjudged bankrupt or insolvent;

(d) the Trustee otherwise becomes incapable of acting.

If the Trustee is removed by the Holders of a majority in principal amount of the Notes and such Holders do not reasonably promptly appoint a successor Trustee, or if the Trustee resigns, is removed by the Company or a vacancy otherwise exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

If a successor Trustee does not take office within 60 calendar days after the retiring Trustee resigns or is removed, the retiring Trustee or the holders of 10% in principal amount of the Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

SECTION 7.09.Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

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

SECTION 7.10.Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Trust Indenture Act § 310(a). The Trustee shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act § 310(b);provided,however, that there shall be excluded from the operation of Trust Indenture Act § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Trust Indenture Act § 310(b)(1) are met.

SECTION 7.11.Preferential Collection of Claims Against Company. The Trustee shall comply with Trust Indenture Act § 311(a), excluding any creditor relationship listed in Trust Indenture Act § 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act § 311(a) to the extent indicated.

SECTION 8.02.Application of Trust Money. The Trustee shall hold in trust money and any shares of Common Stock or other property due in respect of converted Notes deposited with it pursuant to this Article 8. It shall apply the deposited money through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Notes or, in the case of any shares of Common Stock or other property due in respect of converted Notes, in accordance with this Indenture in relation to the conversion of Notes pursuant to the terms hereof.

SECTION 8.03.Repayment to Company. Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest and any shares of Common Stock or other property due in respect of converted Notes that remains unclaimed for two years, and, thereafter, Holders entitled to the money and/or securities must look to the Company for payment as general creditors.

SECTION 8.04.Reinstatement. If the Trustee or Paying Agent is unable to apply any money or to deliver any shares of Common Stock or other property due in respect of converted Notes in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money and any shares of Common Stock or other property due in respect of converted Notes in accordance with this Article 8;provided,however, that, if the Company has made any payment of interest on or principal of any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9

However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective.

No such consent shall be valid or effective for more than 120 calendar days after such record date.

SECTION 9.05.Notation on or Exchange of Notes. If an amendment changes the terms of a Note, the Trustee may require the Holder of the Note to deliver the Note to the Trustee. The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment.

SECTION 9.06.Trustee to Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive, and (subject to Sections 7.01 and 7.02) shall be fully protected in relying upon, in addition to the documents required by Section 11.04, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture and that such amendment is the legal, valid and binding obligation of the Company enforceable against it in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03).

ARTICLE 10

Conversion of Notes

SECTION 10.01.Right to Convert. Upon compliance with the provisions of this Article 10, a Holder may convert, at such Holder’s option, its Notes based on the Conversion Rate (the “Conversion Obligation”). Unless the Company has previously purchased the Notes, at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding March 1, 2024, Holders shall have the right to convert any portion of the principal amount of any Notes that is an integral multiple of $1,000 only under the following circumstances:

(1)Conversion Based on Common Stock Price. On any date during any calendar quarter (and only during such calendar quarter) beginning after September 30, 2019, if the Closing Sale Price for the Common Stock was more than 130% of the applicable Conversion Price on each applicable Trading Day for at least 20 Trading Days (whether or not consecutive) in the period of the 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding previous calendar quarter;

(2)Conversion Upon Specified Corporate Transactions. If the Company:

(i) distributes to all or substantially all holders of its Common Stock any rights, options or warrants (other than in connection with a stockholder rights plan prior to separation of such rights from the shares of its Common Stock) entitling them to purchase, for a period of 45 calendar days or less from the issuance date for such distribution, shares of its Common Stock at a price per share less than the average Closing Sale Price of the Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution; or

(ii) distributes to all or substantially all holders of its Common Stock any cash or other assets, debt securities or rights to purchase securities of the Company (other than pursuant to a rights plan), which distribution has a per share value exceeding 10% of the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the declaration date for such distribution,

then, in each case, the Company shall notify all Holders at least 50 Scheduled Trading Days prior to theEx-Dividend Date for such distribution. Once the Company has given such notice, a Holder may surrender all or a portion of its Notes for conversion at any time until the earlier of 5:00 p.m., New York City time, on the Business Day immediately preceding theEx-Dividend Date or the Company’s announcement that such distribution shall not take place. A Holder may not convert any of its Notes based on this Section 10.01(2) if as a result of holding its Notes such Holder shall otherwise participate in the distribution, without having to convert the Notes, at the same time and on the same terms as holders of the Common Stock as if such Holder held a number of shares of Common Stock equal to the Conversion Rate on the Record Date of such distribution for each $1,000 principal amount of Notes held by such Holder (calculated on an aggregate basis per Holder);

(iii) is a party to (A) a consolidation, merger or binding share exchange pursuant to which the Common Stock would be converted into cash, securities and/or other property or (B) a sale, conveyance, transfer, lease or other disposition of all or substantially all of the property and assets of the Company and its Subsidiaries taken as a whole, in either case that does not constitute a

Fundamental Change. The Company shall notify the Holders of such transaction in writing no later than the actual effective date of such transaction. In such event, a Holder shall have the right to convert its Notes at any time on or after the effective date of such transaction until the earlier of (x) 35 Trading Days after the effective date of such transaction and (y) the second Scheduled Trading Day immediately preceding the Maturity Date.

(3)Conversion Upon a Fundamental Change. If a Fundamental Change occurs, a Holder shall have the right to convert its Notes at any time beginning on the Business Day following the effective date of such Fundamental Change and prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the repurchase date relating to such Fundamental Change until the earlier of (i) the related Fundamental Change Repurchase Date and (ii) the second Scheduled Trading Day immediately preceding the Maturity Date. The Company shall notify all Holders of any Fundamental Change in writing no later than the actual effective date of such transaction. If a Holder has submitted all or a portion of Notes for repurchase, unless such Holder has validly withdrawn such Notes in a timely fashion, such Holder’s conversion rights with respect to the Notes so subject to repurchase shall expire at 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date, unless the Company defaults in the payment of the Fundamental Change Repurchase Price. If a Holder has submitted any Notes for repurchase, such Notes may be converted only if such Holder submits a valid withdrawal notice, and, if the Notes submitted are evidenced by a Global Note, such Holder complies with appropriate Depositary procedures; and

(4)Conversion Upon Satisfaction of Trading Price Condition. During the five Business Day period following any five consecutive Trading Day period in which 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 in this Section 10.01(4), for each Trading Day of such five (5) Trading Day period was less than 98% of the product of the Closing Sale Price of the Common Stock and the Conversion Rate on such Trading Day. The Company shall have no obligation to determine the Trading Price of the Notes unless and until a Holder requests that the Company do so. Once a Holder makes such a request, the Company shall be obligated to, and shall, determine the Trading Price of the Notes for each Trading Day beginning on the Trading Day following the Business Day on which such request is received (provided that if the request is made on a day other than a Business Day, such request shall be deemed made on the first Business Day after receipt) until a Trading Day occurs on which the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Closing Sale Price of the Common Stock and the Conversion Rate on such Trading Day.

Commencing on March 1, 2024, at any time prior to 5:00 p.m., New York City time, on the second Scheduled Trading Day immediately preceding the Maturity Date, a Holder may, at such Holder’s option, convert the Notes, in multiples of $1,000 principal amount.

SECTION 10.02.Conversion Procedures; Settlement Upon Conversion; No Adjustment for Interest or Dividends; Cash Payments in Lieu of Fractional Shares. (a) In order to exercise the conversion right with respect to any Notes in certificated form, a Holder must:

(i) complete and manually sign an irrevocable notice of conversion in the form entitled “Form of Conversion Notice” attached to the reverse of such certificated Note (or a facsimile thereof) (a “Conversion Notice”);

(ii) deliver such Conversion Notice and certificated Note to be converted to the Conversion Agent at the office of the Conversion Agent;

(iii) to the extent any shares of Common Stock issuable upon conversion are to be issued in a name other than the Holder’s, furnish appropriate endorsements and transfer documents as may be required by the Conversion Agent or the Company’s Common Stock transfer agent;

(iv) if required pursuant to Section 2.03(c), pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled; and

(v) if required pursuant to Section 10.02(g), pay all transfer or similar taxes, if any.

In order to exercise the conversion right with respect to any interest in a Global Note, a Holder must:

(i) deliver to the Depositary the appropriate instruction form for conversion pursuant to the Depositary’s conversion program;

(ii) to the extent any shares of Common Stock issuable upon conversion are to be issued in a name other than the Holder’s, furnish appropriate endorsements and transfer documents as may be required by the Conversion Agent or the Company’s Common Stock transfer agent;

(iii) if required pursuant to Section 2.03(c), pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled; and

(iv) if required pursuant to Section 10.02(g), pay all transfer or similar taxes, if any.

The date that the Holder satisfies the foregoing requirements is the “Conversion Date.” The Notes shall be deemed to have been converted immediately prior to 5:00 p.m., New York City time, on the Conversion Date. The Person in whose name any shares of the Common Stock shall be issuable upon such conversion shall become the holder of record of such shares as of 5:00 p.m., New York City time, on the last Trading Day of the relevant Observation Period.

(b) Subject to this Section 10.02 and Section 11.15, upon conversion of any Note, the Company shall, at its election, pay or deliver, as the case may be, to the converting Holder, in full satisfaction of its Conversion Obligation, cash (“Cash Settlement”), shares of Common Stock (“Physical Settlement”) or a combination of cash and shares of Common Stock (“Combination Settlement”), as set forth in this Section 10.02.

(i) All conversions occurring on or after March 1, 2024 shall be settled using the same Settlement Method and the same relative proportion of cash and/or shares of Common Stock as all other conversions occurring on or after March 1, 2024. If the Company elects a Settlement Method for conversions occurring on or after March 1, 2024, the Company shall deliver notice to Holders through the Trustee of such Settlement Method the Company has selected no later than March 1, 2024. If the Company does not timely elect a Settlement Method, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. If the Company has timely elected Combination Settlement in respect of any conversion, but fails to notify the Conversion Agent of the Specified Dollar Amount per $1,000 principal amount of Notes, the Specified Dollar Amount shall be deemed to be $1,000.

(ii) With respect to conversions occurring prior to March 1, 2024, the Company shall use the same Settlement Method (including the same relative proportion of cash and/or shares of Common Stock) for all conversions occurring on the same Conversion Date. Except for any conversions that occur on or after March 1, 2024, the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates. Prior to March 1, 2024, if the Company elects a Settlement Method, the Company shall deliver notice to converting Holders through the Trustee of such Settlement Method the Company has selected no later than the close of business on the Trading Day immediately following the relevant Conversion Date.

(iii) The Company may at any time prior to March 1, 2024 irrevocably elect to settle all Conversion Obligations following such election through Combination Settlement with a Specified Dollar Amount.

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

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

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive VWAP Trading Days during the relevant Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay and deliver, if applicable, to the converting Holder in respect of each $1,000 principal amount of Notes being converted a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive VWAP Trading Days during the relevant Observation Period (plus cash in lieu of any fractional share of Common Stock issuable upon conversion).

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

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

(vi) Subject to the provisions of the Section 10.02 and Section 10.05, the Company shall pay or deliver, as the case may be, the Settlement Amount due in respect of the Conversion Obligation on:

(A) if the Company elects Physical Settlement (i) the second Business Day immediately following the relevant Conversion Date for conversions occurring prior to the final Regular Record Date preceding the Maturity Date or (ii) the Maturity Date for conversions occurring on or after the final Regular Record Date preceding the Maturity Date; or

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

(c) Each conversion will be deemed to have been effected as to any Notes surrendered for conversion on the applicable Conversion Date;provided,however, that the Person in whose name any shares of the Common Stock shall be issuable upon such conversion shall be treated as the Holder of record of such shares as of the close of business on the Conversion Date, in the case of Physical Settlement, or the last VWAP Trading Day of the relevant Observation Period, in the case of combination settlement.

Except as provided in the Notes or in this Article 10, no payment or other adjustment will be made for accrued interest on a converted Note, and accrued interest, if any, will be deemed to be paid by the consideration paid to the Holder upon conversion. Such accrued interest, if any, shall be deemed to be paid in full rather than cancelled, extinguished or forfeited.

(d) If a Holder converts any Notes after 5:00 p.m., New York City time, on the Regular Record Date for an interest payment but prior to the corresponding Interest Payment Date, such Holder shall receive on the corresponding Interest Payment Date the interest accrued and unpaid on such Holder’s Notes, notwithstanding such Holder’s conversion of those Notes prior to the Interest Payment Date, assuming such Holder was the Holder of record on the corresponding Regular Record Date. However, except as provided in the next sentence, at the time such Holder surrenders its Notes for conversion (whether or not such Holder was the Holder of record), such Holder must pay the Company an amount equal to the interest (excluding any Rule 144 Additional Interest, Reporting Additional Interest or Free Transferability Additional Interest) that has accrued and shall be paid on the Notes being converted on the corresponding Interest Payment Date. Such Holder is not required to make such payment:

(1) if such Holder converts its Notes after 5:00 p.m., New York City time, on May 15, 2024, which is the Regular Record Date immediately preceding the Maturity Date;

(2) if such Holder converts its Notes in connection with a Fundamental Change and the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or

(3) to the extent of any overdue interest (including overdue Rule 144 Additional Interest, Reporting Additional Interest or Free Transferability Additional Interest, if any), if overdue interest (or overdue Rule 144 Additional Interest, Reporting Additional Interest or Free Transferability Additional Interest) exists at the time of conversion with respect to such Holder’s Notes.

If a Holder has already delivered a Fundamental Change Repurchase Notice pursuant to Section 3.01 with respect to a Note, such Holder may not surrender that Note for conversion until such Holder has validly withdrawn the Fundamental Change Repurchase Notice in accordance with Section 3.02, except as to a portion of such Note that is not subject to such Fundamental Change Repurchase Notice.

(e) In case any certificated Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the certificated Note so surrendered, without charge to such Holder, a new certificated Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered certificated Note.

(f) Upon the conversion of an interest in a Global Note, the Trustee and the Depositary shall reduce the principal amount of such Global Note in their records.

(g) The issue of stock certificates on conversions of Notes shall be made without charge to the converting holder of Notes for any taxes or duties in respect of the issue thereof. The Company shall not, however, be required to pay any such tax or duty which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Notes converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or duty or shall have established to the satisfaction of the Company that such tax has been paid.

(h) Except as provided in Section 10.02, upon conversion, Holders shall not receive any separate cash payment of accrued and unpaid interest (excluding any Rule 144 Additional Interest, Reporting Additional Interest or Free Transferability Additional Interest) on the Notes. Accrued and unpaid interest (excluding any Rule 144 Additional Interest, Reporting Additional Interest or Free Transferability Additional Interest) to the Conversion Date shall be deemed to be paid in full with the cash paid and shares of Common Stock issued, if any, upon conversion rather than cancelled, extinguished or forfeited.

(i) The Company shall not issue fractional shares of Common Stock upon conversion of the Notes. If any fractional shares of Common Stock would be issuable upon the conversion of any Note or Notes, the Company shall instead pay cash in lieu of fractional share of Common Stock issuable upon conversion in an amount based on (i) the Daily VWAP on the relevant Conversion Date if the Company elects Physical Settlement or (ii) the Daily VWAP on the last VWAP Trading Day of the relevant Observation Period if the Company elects or is deemed to elect Combination Settlement.

(j) Except as described under Section 10.04, the Company shall not make any payment or other adjustment for dividends on any Common Stock issued upon conversion of the Notes.

(k) If the Notes become convertible under any provision of Section 10.01, the Company shall promptly notify the Trustee in writing and issue a press release and make such press release available on its website.

SECTION 10.03.Adjustment to Conversion Rate Upon aNon-Stock Change of Control. If and only to the extent a Holder elects to convert its Notes in connection with a transaction described under clauses (1), (3) (without giving effect to the proviso to clause (3)) or (4) of the definition of Fundamental Change pursuant to which 10% or more of the consideration for the Common Stock (other than cash payments for fractional shares and cash payments made

in respect of dissenters’ appraisal rights) in such Fundamental Change transaction consists of cash or other securities or property that are not shares of common stock traded or scheduled to be traded immediately following such transaction on the NASDAQ Global Select Market, the NASDAQ Global Market or The New York Stock Exchange (or any of their respective successors) (a “Non-Stock Change of Control”), the Conversion Rate shall be increased by an additional number of shares of Common Stock (the “Additional Shares”).

The number of Additional Shares shall be determined by reference to the table below, based on the date on which theNon-Stock Change of Control becomes effective (the “Effective Date”) and the Stock Price paid (or deemed paid) per share for the Common Stock in suchNon-Stock Change of Control.

The Company shall notify the Holders of the Effective Date of anyNon-Stock Change of Control no event than the actual Effective Date of such transaction.

A conversion of the Notes shall be deemed for these purposes to be “in connection with” aNon-Stock Change of Control if the Conversion Notice is received by the Conversion Agent following the Effective Date of theNon-Stock Change of Control but before 5:00 p.m., New York City time, on the Business Day immediately preceding the related Fundamental Change Repurchase Date.

The number of Additional Shares set forth in the table below shall be adjusted in the same manner as and as of any date on which the Conversion Rate of the Notes is adjusted pursuant to this Article 10. The Stock Prices set forth in the first row of the table below (i.e., the column headers) shall be simultaneously adjusted to equal the Stock Prices immediately prior to such adjustment,multipliedby a fraction, the numerator of which shall be the Conversion Rate immediately prior to the adjustment and the denominator of which shall be the Conversion Rate as so adjusted.

The following table sets forth the number of Additional Shares per $1,000 principal amount of Notes by which the Conversion Rate shall be increased upon conversion in connection with aNon-Stock Change of Control:


	Stock Price

Effective Date	$62.53		$65.00		$70.00		$75.00		$80.00		$81.29		$90.00		$100.00		$125.00		$150.00		$175.00

provided,however, that:

(1) if the exact Stock Price is between two Stock Prices listed in the table above under the column titled “Stock Price,” or if the exact Effective Date of suchNon-Stock Change of Control is between two Effective Dates listed in the table above in the rows immediately below the title “Effective Date,” then the number of Additional Shares shall be determined by straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the earlier and later Effective Dates, as applicable, based on a360-day year; and

(2) (a) if the exact Stock Price is greater than $175.00 per share (subject to adjustment in the same manner and at the same time as the Stock Prices listed in the table above), then the Conversion Rate shall not be increased, or (b) if the exact Stock Price is less than $62.53 per share (subject to adjustment in the same manner and at the same time as the Stock Prices listed in the table above), then the Conversion Rate shall not be increased.

In no event shall the total number of shares of Common Stock issuable upon conversion exceed 15.9923 shares per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to this Article 10.

SECTION 10.04.Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows:

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

CR₁

CR₀

OS₁

OS₀

where,


CR₁ =		the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on theEx-Dividend Date for such dividend or distribution or the effective date of such share split or share combination, as the case may be;

CR₀ =		the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on theEx-Dividend Date for such dividend or distribution or the effective date of such share split or share combination, as the case may be;


OS₀ =		the number of shares of Common Stock outstanding immediately prior to 9:00 a.m., New York City time, on theEx-Dividend Date for such dividend or distribution or the effective date of such share split or share combination, as the case may be; and

OS₁ =		the number of shares of the Common Stock that would be outstanding immediately after, and solely as a result of, such dividend, distribution, share split or share combination, as the case may be.

Any adjustment made under this clause (a) shall become effective immediately after 9:00 a.m., New York City time, on suchEx-Dividend Date or effective date, as the case may be.

(b) If the Company shall distribute to all or substantially all holders of its Common Stock any rights, options or warrants (other than in connection with a stockholder rights plan) entitling them to purchase, for a period of 45 calendar days or less from the issuance date for such distribution, shares of the Common Stock at a price per share less than the average Closing Sale Price of the Common Stock for the ten Trading Day period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution, the Conversion Rate shall be increased based on the following formula:

CR₁

CR₀

OS₀ + X

OS₀ + Y

where


CR₁ =		the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on theEx-Dividend Date for such distribution;

CR₀ =		the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on theEx-Dividend Date for such distribution;

OS₀ =		the number of shares of the Common Stock outstanding immediately prior to 9:00 a.m., New York City time, on theEx-Dividend Date for such distribution;

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

Y =		the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Closing Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately preceding theEx-Dividend Date for such distribution.

Any increase made under this clause (b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after 9:00 a.m., New York City time, on theEx-Dividend Date for such distribution. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of the Common Stock are not delivered upon exercise of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered.

In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the Closing Sale Prices for the ten consecutive Trading Day period ending on the Trading Day immediately preceding theEx-Dividend Date for such distribution, and in determining the aggregate offering price of such shares of the Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof and the value of such consideration (if other than cash, to be determined in good faith by the Board of Directors).

Subject in all respects to Section 10.08, rights, options or warrants distributed by the Company to all or substantially all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (each a “Trigger Event”):

(i)

are deemed to be transferred with such Common Stock;

(ii)

are not exercisable; and

(iii)

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

shall be deemed not to have been distributed for purposes of this Section 10.04(b) or Section 10.04(c), as the case may be, (and no adjustment to the Conversion Rate under this Section 10.04(b) or Section 10.04(c), as the case may be, shall be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 10.04(b) or Section 10.04(c), as the case may be.

If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof).

In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 10.04(b) or Section 10.04(c), as the case may be, was made:

(1) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase; and

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

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

(i) dividends or distributions as to which adjustment is required to be effected pursuant to clause (a) or (b) above;

(ii) dividends or distributions paid exclusively in cash as to which adjustment is required to be effected pursuant to clause (d) below;

(iii) rights issued pursuant to a stockholder rights plan of the Company, which are addressed by clause (b) above or in Section 10.08; and

(iv) Spin-Offs described below in the second paragraph of this clause (c),

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

CR₁

CR₀

SP₀

SP₀ – FMV

where,


CR₁ =		the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on theEx-Dividend Date for such distribution;

CR₀ =		the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on theEx-Dividend Date for such distribution;

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

FMV =		the Fair Market Value (as determined in good faith by the Board of Directors or a committee thereof) of the shares of Capital Stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share of the Common Stock on theEx-Dividend Date for such distribution.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than the “SP₀” (as defined above),or if the difference between “SP₀” and “FMV” is less than $1.00, in lieu of the foregoing increase, each Holder shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of the Capital Stock, evidences of the Company’s indebtedness, securities or other assets or property of the Company that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on theEx-Dividend Date for the distribution.

Any increase made under the portion of this clause (c) above shall become effective immediately after 9:00 a.m., New York City time, on theEx-Dividend Date for such distribution.

With respect to an adjustment pursuant to this clause (c) where there has been a payment of a dividend or other distribution on the Common Stock in 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 and such Capital Stock or similar equity interest is listed on a national or regional securities exchange (a “Spin-Off”) the Conversion Rate shall be increased based on the following formula:

CR₁

CR₀

FMV + MP₀

MP₀

where,


CR₁ =		Conversion Rate in effect immediately after 9:00 a.m., New York City time, on theEx-Dividend Date for theSpin-Off;

CR₀ =		the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on theEx-Dividend Date for theSpin-Off;

FMV =		the average of the Closing Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock over the first ten consecutive Trading Day period immediately following, and including, the effective date for suchSpin-Off (such period, the “Valuation Period”); and

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

Any adjustment to the Conversion Rate under the preceding paragraph of this clause (c) shall be made immediately after 9:00 a.m., New York City time, on the day after the last day of the Valuation Period, but shall be given effect as of 9:00 a.m., New York City time, on theEx-Dividend Date for theSpin-Off. The Company shall delay the settlement of any Notes where the final day of the related Observation Period occurs during the Valuation Period. In such event, the Company shall pay the cash and deliver any shares of the Common Stock due upon conversion (based on the adjusted Conversion Rate as described above) on the second Business Day immediately following the last day of the Valuation Period.

(d) If the Company pays any cash dividends or distributions paid exclusively in cash to all or substantially all holders of its Common Stock (other than dividends or distributions made in connection with the Company’s liquidation, dissolution orwinding-up or upon a merger, consolidation or sale, conveyance, transfer, lease or other disposition resulting in a change in the conversion consideration as described under Section 10.05), other than a regular quarterly cash dividend that does not exceed $0.35 per share (the “Dividend Threshold Amount”), the Conversion Rate shall be increased based on the following formula:

CR₁

CR₀

SP₀ – DTA

SP₀ – C

where,


CR₁ =		the Conversion Rate in effect immediately after 9:00 a.m., New York City time, on theEx-Dividend Date for such dividend or distribution;

CR₀ =		the Conversion Rate in effect immediately prior to 9:00 a.m., New York City time, on theEx-Dividend Date for such dividend or distribution;

SP₀ =		the average of the Closing Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding theEx-Dividend Date for such dividend or distribution (or, if the Company declares such dividend or distribution less than eleven Trading Days prior to suchEx-Dividend Date, ten shall be replaced with a smaller number of Trading Days that shall have occurred after, and not including, such declaration date and prior to, but not including, suchEx-Dividend Date);

DTA =		the Dividend Threshold Amount in effect on theEx-Dividend Date for such dividend or distribution;provided that if the dividend or distribution is not a regular quarterly dividend, the Dividend Threshold Amount shall be deemed to be zero; and

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

The Dividend Threshold Amount is subject to adjustment on an inversely proportional basis whenever the Conversion Rate is adjusted;provided that no adjustment shall be made to the Dividend Threshold Amount for any adjustment to the Conversion Rate under this clause (d).

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), or if the difference between “SP₀” and “C” is less than $1.00, in lieu of the foregoing increase, each Holder shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received as if such Holder owned a number of shares of the Common Stock equal to the Conversion Rate in effect on theEx-Dividend Date for such cash dividend or distribution.

Any increase made under this clause (d) shall become effective immediately after 9:00 a.m., New York City time, on theEx-Dividend Date for such cash dividend or distribution.

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

CR₁

CR₀

AC + ( SP₁ × OS₁)

OS₀ × SP₁

where,


CR₁ =		the Conversion Rate in effect immediately after 5:00 p.m., New York City time, on the Trading Day immediately following the Expiration Date;

CR₀ =		the Conversion Rate in effect immediately prior to 5:00 p.m., New York City time, on the Trading Day immediately following the Expiration Date;

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

SP₁ =		the average of the Closing Sale Prices of the Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date (the “Averaging Period”);

OS₁ =		the number of shares of the Common Stock outstanding immediately after 5:00 p.m., New York City time, on the Expiration Date (after giving effect to such tender offer or exchange offer); and

OS₀ =		the number of shares of the Common Stock outstanding immediately prior to 5:00 p.m., New York City time, on the Expiration Date (prior to giving effect to such tender offer or exchange offer).

Any adjustment to the Conversion Rate under this clause (e) shall be made immediately prior to 9:00 a.m., New York City time, on the day following the last day of the Averaging Period, but shall be given effect as of 9:00 a.m., New York City time, on the Trading Day immediately following the Expiration Date. The Company shall delay the settlement of any Notes where the final day of the related Observation Period occurs during the Averaging Period. In such event, the Company shall pay cash and deliver any shares of the Common Stock due upon conversion (based on the adjusted Conversion Rate as described above) on the second Business Day immediately following the last day of the Averaging Period.

Notwithstanding the foregoing, if a Conversion Rate adjustment becomes effective on anyEx-Dividend Date as described above and a Holder has converted its Notes prior to suchEx-Dividend Date such that suchEx-Dividend Date falls during the relevant Observation Period and such Holder would be treated as the record holder of the shares of the Common Stock to be issued upon conversion on the Record Date of the relevant dividend, distribution or other event, then, notwithstanding the foregoing Conversion Rate adjustment provisions, such Conversion Rate adjustment shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of such shares of the Common Stock (which shall be calculated on an unadjusted basis) and participate in the related dividend, distribution or other event giving rise to such adjustment.

(f) To the extent permitted by law and any applicable stock exchange rules (including, if necessary, in compliance with any applicable stock exchange shareholder approval requirement), the Company (i) may increase the Conversion Rate by any amount for a period of at least 20 Business Days and (ii) may (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentences, the Company shall deliver a notice of the increase to the Trustee and Holders, which notice shall state the increased Conversion Rate and the period during which it shall be in effect.

(g) All calculations and other determinations under this Article 10 shall be made by the Company and shall be made to the nearestone-ten thousandth (1/10,000th) of a share. No adjustment pursuant to this Section 10.04 shall be made to the Conversion Rate unless such adjustment would require a change of at least 1% in the Conversion Rate then in effect at such time. However, any adjustments that are less than 1% of the Conversion Rate shall be carried forward and taken into account in any subsequent adjustment, regardless of whether the aggregate adjustment is less than 1%, (i) upon conversion of any Notes or (ii) prior to any Fundamental Change Repurchase Date, unless such adjustment has already been made.

(h) Whenever the Conversion Rate is adjusted as herein provided, the Company shall issue a press release containing the relevant information, including, but not limited to, any applicable declaration date, and make this information available on its website. In addition, the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate setting forth any applicable declaration date and the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall send such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Register within 20 calendar days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(i) Notwithstanding any of the foregoing clauses in this Section 10.04, the Conversion Rate shall not be adjusted pursuant to this Section 10.04 if as a result of holding the Notes the Holders shall otherwise participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock in any of the transactions that would otherwise give rise to adjustment pursuant to this Section 10.04 without conversion of such Holder’s Notes as if such Holder held a number of shares of Common Stock equal to the Conversion Rate on the Record Date of such distribution for each $1,000 principal amount of Notes held by such Holder (calculated on an aggregate basis per Holder).

(j) Except as stated in this Section 10.04 and Section 10.08, the Company shall not adjust the Conversion Rate for the issuances of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or rights to purchase shares of Common Stock or such convertible or exchangeable securities.

(k) For purposes of this Section 10.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

(l) Whenever any provision of this Article 10 requires the Company to calculate the Closing Sale Prices, the VWAPs, the Daily Conversion Values or the Conversion Settlement Amount over, or based on, a span of multiple days (including an Observation Period), the Company shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where theEx-Dividend Date of the event occurs, at any time during the period when the Closing Sale Prices, the VWAPs, the Daily Conversion Values or the Conversion Settlement Amount is to be calculated.

SECTION 10.05.Effect of Reclassifications, Business Combinations, Asset Sales and Corporate Events. If the Company:

(a) reclassifies or changes its Common Stock (other than changes resulting from a subdivision or combination); or

(b) consolidates or merges with or into or enters into a binding share exchange with any Person or sells, conveys, transfers, leases or otherwise disposes of all or substantially all of the property and assets of the Company and its Subsidiaries taken as a whole to another Person,

and, in either case as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities or other property or assets (including cash or any combination thereof), then at the effective date of such transaction (a “Merger Event”), the right to convert each outstanding $1,000 principal amount of Notes based on the Common Stock shall, without the consent of any Holders, be changed into a right to convert each such Note based on the kind and amount of stock, other securities or other property or assets (including cash or any

combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or be entitled to receive (the “Reference Property”). If the Merger Event causes the Common Stock to be converted into or exchanged for the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the Reference Property into which the Notes shall become convertible shall be deemed to be the kind and amount of consideration actually received by holders of a majority of the Common Stock that voted for such an election (if electing between two types of consideration) or holders of a plurality of the Common Stock that voted for such an election (if electing between more than two types of consideration), as the case may be. In all cases the provisions under Section 10.02 shall continue to apply with respect to the calculation of the Conversion Settlement Amount, with the Daily Conversion Value, Daily Settlement Amount and the VWAP determined based on a unit of Reference Property that a holder of one share of the Common Stock would have received in such transaction;provided,however, that if the holders of the Common Stock receive only cash in such Merger Event, the Conversion Settlement Amount shall equal the Conversion Rate in effect on the Conversion Date,multipliedby the price paid per share of Common Stock in such transaction, and settlement of any conversion thereafter shall occur on the second Business Day following the applicable Conversion Date. The Company shall not become a party to any such transaction unless its terms are consistent with the foregoing.

In connection with any Merger Event, the Dividend Threshold Amount shall be subject to adjustment as described in clause (1), clause (2) or clause (3) below, as the case may be.

(1) In the case of a Merger Event in which the Reference Property is composed entirely of shares of common stock (the “Merger Common Stock”), the Dividend Threshold Amount at the effective time of such Merger Event shall be equal to (x) the Dividend Threshold Amount immediately prior to the effective time of such Merger Event,dividedby (y) the number of shares of Merger Common Stock that a holder of one share of Common Stock would receive in such Merger Event (such quotient rounded down to nearest cent) (subject to adjustment as provided in Section 10.04(d)).

(2) In the case of a Merger Event in which the Reference Property is composed in part of shares of Merger Common Stock, the Dividend Threshold Amount at the effective time of such Merger Event shall be equal to (x) the Dividend Threshold Amount immediately prior to the effective time of such Merger Event,multipliedby (y) the Merger Valuation Percentage for such Merger Event (such product rounded down to nearest cent) (subject to adjustment as provided in Section 10.04(d)).

(3) For the avoidance of doubt, in the case of a Merger Event in which the Reference Property is composed entirely of consideration other than shares of common stock, the Dividend Threshold Amount at and after the effective time of such Merger Event shall be equal to zero.

In connection with the preceding paragraph, the following terms shall have the following meanings:

(1) the “Merger Valuation Percentage” for any Merger Event shall be equal to (x) the arithmetic average of the Closing Sale Prices of one share of such Merger Common Stock over the relevant Merger Valuation Period (determined as if references to “Common Stock” in the definition of “Closing Sale Price” were references to the “Merger Common Stock” for such Merger Event)dividedby (y) the arithmetic average of the Closing Sale Prices of one share of Common Stock over the relevant Merger Valuation Period.

(2) the “Merger Valuation Period” for any Merger Event means the five consecutive Trading Day period immediately preceding, but excluding, the effective date for such Merger Event.

The Company shall cause notice of the execution of such supplemental indenture to be sent to each Holder, at the address of such Holder as it appears on the Register of the Notes maintained by the Registrar, within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

The above provisions of this Section 10.05 shall similarly apply to successive reclassifications, changes, consolidations, mergers, binding share exchanges, sales, conveyances, transfers, leases or other dispositions.

SECTION 10.06.Certain Covenants. (a) The Company shall, prior to the issuance of any Notes hereunder, and from time to time as may be necessary, reserve out of its authorized but unissued Common Stock or shares of Common Stock held in treasury, a sufficient number of shares of Common Stock, free of preemptive rights, to permit the conversion of the Notes.

(b) The Company covenants that all shares of Common Stock issued upon conversion of Notes shall be duly and validly issued and fully paid andnon-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

(c) The Company shall endeavor promptly to comply with all federal and state securities laws regulating the issuance and delivery of shares of Common Stock upon the conversion of Notes, if any, and shall cause to have listed or quoted and shall keep listed or quoted all such shares of Common Stock on each U.S. national securities exchange or automatic quotation system orover-the-counter or other domestic market on which the Common Stock is then listed or quoted.

SECTION 10.07.Notice to Holders Prior to Certain Actions. Except where notice is required pursuant to Section 10.01, in case:

(a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 10.04; or

(b) the Company shall authorize the granting to all or substantially all of the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants that would require an adjustment in the Conversion Rate pursuant to Section 10.04; or

(c) of any reclassification of the Common Stock of the Company (other than a share split or share combination of its outstanding Common Stock, or a change in par value), or of any share exchange, consolidation or merger to which the Company is a party and for which approval of any shareholders of the Company is required, or of the conveyance, transfer, sale, lease or other disposition of all or substantially all of the consolidated assets of the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company;

the Company shall cause to be filed with the Trustee and to be mailed (or otherwise transmitted in accordance with the applicable procedures of the Depositary) to each Holder at his address appearing on the Register provided for in Section 2.05, as promptly as possible but in any event at least 10 calendar days prior to the applicable date hereinafter specified, a notice stating:

(x) the declaration date of the dividend or other distribution;

(y) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined; or

(z) the date on which such reclassification, share exchange, consolidation, merger, conveyance, transfer, sale, lease or other disposition, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

SECTION 10.08.Shareholder Rights Plans. To the extent that any shareholders’ rights plan adopted by the Company is in effect upon conversion of the Notes, the Holders shall receive, in addition to any Common Stock due upon conversion, the rights under the applicable rights agreement unless the rights have separated from the Common Stock at the time of conversion of the Notes, in which case, the Conversion Rate shall be adjusted as if the Company distributed to all holders of the Common Stock shares of the Capital Stock, evidences of indebtedness or assets as provided in Section 10.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

SECTION 10.09.Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 10. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 10.05 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 10.05 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 10.01 has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 10.01 with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 10.01.

SECTION 10.10.Exchange-Related Limitations. Notwithstanding anything to the contrary in the Notes or in this Indenture, in connection with limitations imposed by the continued listing standards of the NASDAQ Global Select Market, in the event of an increase in the Conversion Rate that would result in the Notes, in the aggregate, becoming convertible into shares of Common Stock in excess of 20% of the Common Stock outstanding as of the issue date of the Notes, the Company, at its election, shall either (i) obtain shareholder approval of such issuances, in accordance with the shareholder approval rules contained in such listing standards, or (ii) pay cash in lieu of delivering any shares of Common Stock otherwise deliverable upon conversion in excess of such limitations based on the average Daily VWAP of the applicable Observation Period. If the Company pays cash in lieu of delivering shares of Common Stock pursuant to this Section 10.10, it will notify the Trustee, the Conversion Agent and the Holders of the maximum number of shares it will deliver per $1,000 principal amount of converted Notes in respect of the relevant conversion.

SECTION 10.11.Exchange in Lieu of Conversion

(a) When a Holder surrenders its Notes for conversion, the Company may, at its election, surrender, on or prior to the close of business on the Business Day following the relevant Conversion Date, such Notes to a financial institution designated by the Company (the “Designated Institution”) for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion for exchange in lieu of conversion, the Designated Institution must agree to timely deliver, in exchange for such Notes, the cash, shares of Common Stock or combination of cash and shares of Common Stock, at the Company’s election, that would otherwise be due upon conversion as described in Section 10.02 above and in respect of which the Company has notified converting Holders. If the Company makes the election described above, the Company shall, by the close of business the Business Day following the relevant Conversion Date, notify in writing the Holder surrendering Notes for conversion, the Trustee and the Conversion Agent (if other than the Trustee) that it has made such election. In addition, the Company shall concurrently notify the Designated Institution of the settlement method elected with respect to such conversion and the relevant deadline for delivery of the consideration due upon conversion. Any Notes exchanged by the Designated Institution will remain outstanding.

(b) If the Designated Institution agrees to accept any Notes for exchange but does not timely deliver the related consideration due upon conversion to the Holder, or if the Designated Institution does not accept such Notes for exchange, the Company shall, within the time period specified in Section 10.02(b), convert such Notes into cash, shares of Common Stock or combination of cash and shares of Common Stock, at the Company’s election, in accordance with the provisions of Section 10.02.

(c) For the avoidance of doubt, in no event will the Company’s designation of a Designated Institution pursuant to this Section 10.11 require the Designated Institution to accept any Notes for exchange.

[FORM OF REVERSE SIDE OF NOTE]

2.00% Senior Convertible Note due 2024

INTERDIGITAL, INC., a Pennsylvania corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), issued this Note under an Indenture, dated as of June 3, 2019 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee, to which reference is hereby made for a statement of the respective rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders and of the terms upon which the Notes are, and are to be, authorized and delivered. All terms used in this Note which are defined in the Indenture shall have the meaning assigned to them in the Indenture.

1.	Further Provisions Relating to Interest

(a)Additional Interest. If, at any time during thesix-month period beginning on, and including, the date which is six months after the last original issuance date of the Notes, the Company fails to timely file any document or report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than current reports on Form8-K), the Company shall pay additional interest (the “Rule 144 Additional Interest”) on the Notes which shall accrue on all transfer restricted Notes at an annual rate of 0.50% per annum of the principal amount of such Notes outstanding for each day during such period for which the Company’s failure to file continues.

(b) In the event of the Company’s failure to comply with the covenant in Section 4.03(a) of the Indenture and the Company’s failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act (which also relate to the provision of reports), the Company may elect that the sole remedy for the resulting Event of Default for the 360 days after the occurrence of such Event of Default shall consist exclusively of the right to receive additional interest (the “Reporting Additional Interest”) on the Notes at an annual rate equal to (i) 0.25% of the outstanding principal amount of the Notes from the first date of the occurrence of such Event of Default to, but not including, the 180^th day thereafter (or such earlier date on which the Event of Default relating to the Company’s reporting obligations pursuant to Section 4.03(a) of the Indenture and Section 314(a)(1) of the Trust Indenture Act shall have been cured or waived) and (ii) 0.50% of the outstanding principal amount of the Notes from the 181^st date following the occurrence to the 360^th day after the first date of the occurrence of such Event of Default (or such earlier date on which the Event of Default relating to the Company’s reporting obligations pursuant to Section 4.03(a) of the Indenture and Section 314(a)(1) of the Trust Indenture Act shall have been cured or waived). In the event the Company does not elect to pay the Reporting Additional Interest upon an Event of Default in accordance with Section 6.13 of the Indenture, the Notes shall be subject to acceleration pursuant to Section 6.02 of the Indenture. This Reporting Additional Interest shall be payable in arrears on the same dates and in the same manner as regular interest on the Notes. On such 360^th day, if such Event of Default is continuing, such Reporting Additional Interest shall cease to accrue and the Notes shall be

A-5

subject to acceleration as provided in Section 6.02 of the Indenture. For the avoidance of doubt, in the event Rule 144 Additional Interest is triggered under Section 4.12 of the Indenture or Free Transferability Additional Interest is triggered under Section 4.13 of the Indenture during any period in which the Company has elected that the accrual of Reporting Additional Interest be the sole remedy for any such Event of Default, no Reporting Additional Interest shall be payable pursuant to Section 6.13 of the Indenture for so long as Rule 144 Additional Interest is accruing and payable pursuant to Section 4.12 of the Indenture or Free Transferability Additional Interest is accruing under Section 4.13 of the Indenture.

(c) Further, if, and for so long as, the Restricted Note Legend on the Notes has not been removed, the Notes are assigned a restricted CUSIP or the Notes are not otherwise Freely Transferable by holders other than Affiliates of the Company or Persons that were Affiliates of the Company during the immediately preceding three months (without restrictions pursuant to U.S. securities law or the terms of the Indenture or the Notes) as of the 380th day after the last date of original issuance of the Notes, the Company shall pay additional interest (“Free Transferability Additional Interest”) on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the Notes are Freely Transferable as described above by holders other than Affiliates of the Company or Persons that were Affiliates of the Company during the immediately preceding three months. No Free Transferability Additional Interest shall be payable pursuant to Section 4.13 of the Indenture for so long as Rule 144 Additional Interest is accruing and payable pursuant to Section 4.12 of the Indenture;provided,however, that, for the avoidance of any doubt, Free Transferability Additional Interest shall accrue and be payable pursuant to Section 4.13 of the Indenture once such Rule 144 Additional Interest ceases to accrue and be payable pursuant to Section 4.12 of the Indenture.

(d) Except as otherwise specifically set forth, all references herein to “interest” include Defaulted Interest, if any, Rule 144 Additional Interest, if any, Reporting Additional Interest, if any, and Free Transferability Additional Interest, if any.

2.	Method of Payment

The Company shall pay interest on the Notes (except Defaulted Interest) to the Persons who are registered holders of Notes at 5:00 p.m., New York City time, on the May 15 and November 15 next preceding the Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts.

The Company shall pay interest on:

(i) any Global Notes to the Depositary in immediately available funds;

(ii) any Notes in certificated form by wire transfer in immediately available funds to the Holder of such Notes duly delivered to the Trustee at least five Business Days prior to the relevant Interest Payment Date.

A-6

3.	Paying Agent, Registrar and Conversion Agent

Initially, The Bank of New York Mellon Trust Company, N.A., a national banking association organized under the laws of the United States (the “Trustee”), shall act as Paying Agent, Registrar and Conversion Agent. The Company may appoint and change any Paying Agent, Registrar orco-registrar or Conversion Agent without notice. The Company or any of its Wholly Owned Subsidiaries that is not a Foreign Subsidiary may act as Paying Agent, Registrar orco-registrar.

4.Sinking Fund

The Notes are not subject to any sinking fund.

5.	Repurchase of Notes at the Option of Holders

Upon the occurrence of a Fundamental Change, the Holder has the right to require the Company to repurchase all or part of such Holder’s Notes in a principal amount thereof that is equal to $1,000 in principal amount or whole multiples thereof on the Fundamental Change Repurchase Date at a price, payable in cash, equal to 100% of the principal amount of the Notes such Holder elects to require the Company to repurchase, plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date. The Company or, at the written request of the Company, the Trustee shall provide to all record Holders a notice of the occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or before the tenth Business Day after the occurrence of such Fundamental Change.

6.	Conversion

Subject to the provisions of the Indenture, the Holder hereof may convert, during certain periods and upon the occurrence of certain conditions specified in the Indenture and prior to 5:00 p.m., New York City time, on the second Scheduled Trading Day immediately preceding the Maturity Date, any Notes or portion thereof that is $1,000 or multiples thereof at a Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture, upon surrender of this Note, together with a conversion notice as provided in the Indenture and this Note, to the Company at the office or agency of the Company maintained for that purpose and, unless the shares issuable on conversion are to be issued in the same name as this Note, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or by its duly authorized attorney. Upon conversion, the Company shall satisfy its Conversion Obligation in cash, shares of Common Stock or a combination of cash and Shares of Common Stock, if applicable. The initial Conversion Rate shall be 12.3018 shares of Common Stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $81.29 per share of Common Stock). No fractional shares of Common Stock shall be issued upon any conversion, but an adjustment in cash shall be paid to the Holder, as provided in the Indenture, in respect of any fraction of a share that would otherwise be issuable upon the surrender of any Note or Notes for conversion. No adjustment shall be made for dividends or any shares issued upon conversion of such Note except as provided in the Indenture.

A-7

7.	Denominations, Transfer, Exchange

The Notes are in registered form without coupons in denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Notes in accordance with the Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture.

8.	Persons Deemed Owners

The registered Holder of this Note may be treated as the owner of it for all purposes.

9.	Unclaimed Money

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest and any shares of Common Stock or other property due in respect of converted Notes that remains unclaimed for two years, and, thereafter, Holders entitled to the money and/or securities must look to the Company for payment as general creditors.

10.	Amendment, Waiver

Subject to certain exceptions, the Indenture contains provisions permitting a modification or amendment of the Indenture or the Notes with the written consent or affirmative vote of the Holders of a majority in aggregate principal amount of the then outstanding Notes and the waiver of any Event of Default (other than with respect to nonpayment, a failure to satisfy the Conversion Obligation or a provision that cannot be amended without the written consent of each Holder affected) or noncompliance with any provision with the written consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes.

In addition, the Indenture permits an amendment of the Indenture or the Notes without the consent of any Holder under circumstances specified in the Indenture. The Indenture also permits an amendment of the Indenture or the Notes only with the consent of any Holder affected thereby under circumstances specified in the Indenture.

11.	Defaults and Remedies

Except as specified in the Indenture, if an Event of Default occurs (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company) and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the outstanding Notes may declare the principal amount of the Notes and accrued and unpaid interest on the outstanding Notes to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company occurs, the principal amount of the Notes and accrued and unpaid interest on the outstanding Notes shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the holders of a majority in aggregate principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

A-8

If an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security reasonably satisfactory to the Trustee against any loss, liability or expense. Subject to certain exceptions, no Holder may pursue any remedy with respect to the Indenture or the Notes unless (i) such Holder has given the Trustee written notice of an Event of Default, (ii) holders of at least 25% in aggregate principal amount of the outstanding Notes have made a written request to the Trustee to pursue the remedy and offered reasonable security or indemnity against any costs, liability or expense of the Trustee, (iii) the Trustee fails to comply with such request within 60 calendar days after receipt of such request and the offer of indemnity and (iv) the Trustee has not received an inconsistent direction from the holders of a majority in aggregate principal amount of the outstanding Notes. Subject to certain restrictions, the Holders of a majority in aggregate principal amount of the outstanding Notes are given the right to direct the time, method and place of any proceedings for any remedy available to the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability or expense for which the Trustee has not received adequate indemnity as determined by it in good faith. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification or security reasonably satisfactory to it in its sole discretion against all losses, liabilities and expenses caused by taking or not taking such action.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Company and the holder of the Notes, the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the Indenture prescribed.

12.	Trustee Dealings with the Company

Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

13.	No Recourse Against Others

No past, present or future director, officer, employee, incorporator, shareholder or partner, as such, of the Company shall have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. By accepting a Note, each Holder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Notes.

A-9

14.	Authentication

This Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Note.

16.	Governing Law

THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

17.	CUSIP Numbers and ISINs

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers and ISINs to be printed on the Notes and has directed the Trustee to use CUSIP numbers and ISINs in notices of repurchase as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of repurchase and reliance may be placed only on the other identification numbers placed thereon.
