Physical Notes shall be issued and delivered by the Company:

(i)    to each Person that the Depositary identifies as a beneficial owner of the related Global Notes only if (x) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, or (y) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days; or

(ii)    if an Event of Default with respect to the Notes has occurred and is continuing, to each beneficial owner of any Global Note who requests that its beneficial interests therein be issued as a Physical Note.

The Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (ii) above, a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i)(a) or (i)(b) above, Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled.

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(d) shall be registered in such names and in such authorized denominations as the

14

Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

Notwithstanding anything to the contrary in the Indenture or the Notes, following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Physical Note in accordance with the provisions of the Indenture.

Section 5.03     Acceleration; Rescission and Annulment.  If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 5.02(h) or Section 5.02(i) with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company)), either the Trustee by notice in writing to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding by notice in writing to the Company and the Trustee may declare 100% of the

The Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Company and the Trustee, may rescind and annul any such acceleration with respect to the Notes (except with respect to nonpayment of the principal of and accrued and unpaid interest, if any, on the Notes; with respect to a Default in respect of a provision that under Section 9.03 of the Base Indenture and Section 8.02 cannot be amended without the consent of each affected Holder; and with respect to the failure to deliver the consideration due upon conversion of the Notes) and its consequences if:

If the Company so elects to pay Additional Interest, any such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 271st calendar day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with the Reporting Obligations is not cured or waived prior to such 271st calendar day), the Notes shall be subject to acceleration under Section 5.03. The provisions of this Section 5.04 shall not affect the rights of Holders of the Notes in the event of the occurrence of any other Event of Default.

Section 5.05     Payments of Notes on Default; Suit Therefor.  If an Event of Default described in clause (a) or (b) of Section 5.02 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal (including the Fundamental Change Purchase Price, if applicable), and interest, if any, with interest on any overdue principal, and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.07 of the Base Indenture. If the Company shall fail to first pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

21

relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under Section 7.07 of the Base Indenture, and to take any other action with respect to such claims, including participating as a member of any official committee of creditors, as it reasonably deems necessary or advisable, unless prohibited by law or applicable regulations, and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.07 of the Base Indenture, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

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

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

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

In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 5.10 or any rescission and annulment pursuant to Section 5.03 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though no such proceeding had been instituted.

it being understood and intended, and being expressly covenanted by the Holder of every Note with every Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of the Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under the Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 5.07, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

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

Section 5.08     Proceedings by Trustee.  In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by the Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law.

Section 5.09     Remedies Cumulative and Continuing.  Except as provided in the last sentence of Section 2.08(b) of the Base Indenture, all powers and remedies given by this Article 5 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in the Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 5.07, every power and remedy given by this Article 5 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

Section 5.10     Direction of Proceedings and Waiver of Defaults by Majority of Holders.  Subject to Section 7.02(f) of the Base Indenture, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided , however , that (a) such direction shall not be in conflict with any rule of law or with the Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default hereunder (except (w) with respect to nonpayment of the principal of and accrued and unpaid interest, if any, on the Notes; (x) with respect to the Company’s failure to repurchase the Notes when required under this Supplemental Indenture; (y) with respect to a Default in respect of a provision that under Section 8.02 hereof or Section 9.03 of the Base Indenture cannot be amended without the consent of each affected Holder; or (z) with respect to the failure to deliver the consideration due upon conversion of the Notes). The Indenture shall not be deemed to contain the provision set forth in clause (B) of Section 316(a)(1) of the TIA. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 5.10, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Prior to taking any action under the Indenture at the Holders’ instruction, the Trustee shall be entitled to security from or indemnification by the Holders satisfactory to it against all losses, liabilities and expenses.

Section 5.11     Notice of Defaults.  If a Default has occurred and is continuing and is known to a Responsible Officer of the Trustee, the Trustee shall mail to each Holder of the Notes, at the address of such Holder included in the Note Register, notice of such Default within 90 days after it occurs; provided that, except in the case of a Default in the payment of the principal of, or interest on, any of the Notes (including a Default in the payment of the Fundamental Change Purchase Price) or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of the Holders of the Notes. This Section 5.11 shall supersede Section 7.05 of the Base Indenture, and any reference in the Base Indenture to such Section 7.05 thereof shall be deemed to refer instead to this Section 5.11. The proviso set forth in Section 315(b) of the TIA shall not apply with respect to the Notes.

Section 5.12     Undertaking to Pay Costs.  All parties to the Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may,

25

in its discretion, require, in any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 5.12 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal (including the Fundamental Change Purchase Price, if applicable) of, accrued and unpaid interest, if any, on, any Note on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 9.

ARTICLE 6

CONCERNING THE HOLDERS

Section 6.01     Action by Holders.  Whenever in the Indenture it is provided that the Holders of a specified percentage of the aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 7, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix, in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than 15 days prior to the date of commencement of solicitation of such action.

Section 6.02     Proof of Execution by Holders.  Subject to the provisions of Section 7.01 of the Base Indenture, Section 7.02 of the Base Indenture and Section 7.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 7.06.

26

conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any authenticating agent nor any Paying Agent nor any Conversion Agent nor any Registrar shall be affected by any notice to the contrary. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note.

Section 6.04     Company-Owned Notes Disregarded.  This Section 6.04 shall supersede Section 2.10 of the Base Indenture, and any reference in the Base Indenture to Section 2.10 thereof shall be deemed to refer instead to this Section 6.04. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under the Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer knows are so owned shall be so disregarded. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01 of the Base Indenture, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Section 6.05     Revocation of Consents; Future Holders Bound.  Notwithstanding anything to the contrary in Section 9.05 of the Base Indenture, at any time prior to (but not after) the evidencing to the Trustee, as provided in Section 6.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in the Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 6.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

Any record so signed and verified shall be conclusive evidence of the matters therein stated.

ARTICLE 9

CONVERSION OF NOTES

Section 9.01     Conversion Privilege.  (a) Subject to and upon compliance with the provisions of this Article 9, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 in principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of one or more of the conditions described in Section 9.01(b), at any time prior to the close of business on the Business Day immediately preceding December 15, 2021 under the circumstances and during the periods set forth in Section 9.01(b), and (ii) on or after December 15, 2021 until the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 3.0534 shares of Common Stock (subject to adjustment as provided in this Article 9, the “ Conversion Rate ”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 9.02, the “ Conversion Obligation ”).

(b)    (i) Prior to the close of business on the Business Day immediately preceding December 15, 2021, a Holder of Notes may surrender its Notes for conversion during the five Business Day period immediately after any five consecutive Trading Day period (the “ Measurement Period ”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last

31

Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day, subject to compliance with the procedures and conditions described in this subsection (b)(i). The Company shall provide written notice to the Bid Solicitation Agent of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. At such time, the Company shall instruct the Bid Solicitation Agent to (or, if the Company is acting as Bid Solicitation Agent, the Company shall) determine the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If the Trading Price condition set forth above has been met on any Trading Day, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing on such Trading Day, in accordance with Section 10.02 of the Base Indenture. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such Trading Day, the Company shall promptly so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee), in accordance with Section 10.02 of the Base Indenture. If the Company does not, when it is required to, instruct the Bid Solicitation Agent to (or, if the Company is acting as Bid Solicitation Agent, the Company does not) obtain bids, or if the Company instructs the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence and the Bid Solicitation Agent fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure.

(ii)    If, prior to the close of business on the Business Day immediately preceding December 15, 2021, the Company elects to:

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

(B)    distribute to all or substantially all holders of the Common Stock the Company’s assets, debt securities or rights to purchase securities of the

32

Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the declaration date for such distribution,

then, in either case, the Company shall notify all Holders of the Notes at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution, in accordance with Section 10.02 of the Base Indenture. Once the Company has given such notice, Holders may surrender their Notes for conversion at any time until the earlier of:

(iii)    Prior to the close of business on the Business Day immediately preceding December 15, 2021, if:

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

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

(C)    if the Company is a party to a consolidation, merger, combination, statutory or binding share exchange or similar transaction involving the Company, pursuant to which the Common Stock would be converted into, or exchanged for, cash, securities or other property or assets, or any sale, conveyance, lease or other transfer or similar transaction in one transaction or a series of transactions of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole,

the Notes may be surrendered by a Holder for conversion at any time from or after the date that is 30 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after the Company gives notice of such transaction) until the close of business on the 35th Trading Day after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the close of business on the Business Day immediately preceding the relevant Fundamental Change Purchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) as promptly as practicable following the date the Company publicly announces such transaction; provided that the Company shall deliver such notice in no event later than the actual effective date.

(iv)    Prior to the close of business on the Business Day immediately preceding December 15, 2021, a Holder may surrender its Notes for conversion during any calendar quarter commencing after the calendar quarter ending on June 30, 2017 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least

33

20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. The Company shall determine at the beginning of each calendar quarter commencing after June 30, 2017 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Holders if the Notes become convertible in accordance with this clause (iv), within five Business Days of the Notes so becoming convertible, in accordance with Section 10.02 of the Base Indenture.

Section 9.02     Conversion Procedure; Settlement Upon Conversion.

(a)    Subject to this Section 9.02, Section 9.03(b) and Section 9.07(a), upon conversion of any Note, the Company shall, at its election, pay or deliver, as the case may be, to the converting Holder, in full satisfaction of its Conversion Obligation, cash (“ Cash Settlement ”), shares of Common Stock (“ Physical Settlement ”) or a combination of cash and shares of Common Stock (“ Combination Settlement ”), as set forth in this Section 9.02.

(1)     All conversions occurring on or after December 15, 2021 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 December 15, 2021. If the Company elects a Settlement Method for any conversions occurring on or after December 15, 2021, the Company shall deliver notice to Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such Settlement Method the Company has selected no later than December 15, 2021. 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 converting Holders through the Trustee of the Specified Dollar Amount per $1,000 principal amount of Notes, the Specified Dollar Amount shall be deemed to be $1,000.

(2)     Except for any conversions that occur on or after December 15, 2021, 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 December 15, 2021, 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 December 15, 2021, if the Company elects a Settlement Method, the Company shall deliver notice to converting Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such Settlement Method the Company has selected no later than the close of business on the second Trading Day immediately following the relevant Conversion Date. If the Company does not timely elect a Settlement Method in respect of a particular Conversion Date, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement with respect to that Conversion Date and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. If the Company has

timely elected Combination Settlement in respect of any such conversion, but fails to notify the Conversion Agent of the Specified Dollar Amount per $1,000 principal amount of Notes, the Specified Dollar Amount per $1,000 principal amount shall be deemed to be $1,000.

(3)     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 “ Conversion Settlement Amount ”) shall be computed by the Company as follows:

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

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

(4)    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 applicable 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.

35

(b)    Subject to Section 9.02(e), to convert a Note as set forth above, (i) in the case of a Global Note, the beneficial owner thereof shall comply with the Applicable Procedures for converting a beneficial interest in a Global Note and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 9.02(g) and (ii) in the case of a Physical Note, the Holder thereof shall:

(1)    complete, manually sign and deliver an irrevocable notice or facsimile thereof to the Conversion Agent and to the Trustee, if not the Conversion Agent, as set forth in the Form of Notice of Conversion (a “ Notice of Conversion ”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered;

(2)    surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent;

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

(4)    if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 9.02(g).

The Conversion Agent shall notify the Company of any conversion pursuant to this Article 9 on the Conversion Date for such conversion.

No Holder may surrender Notes for conversion if such Holder has also delivered a Fundamental Change Purchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Purchase Notice in accordance with Section 10.02 (or, in the case of a Global Note, if such Holder has requested a repurchase of Notes pursuant to Section 10.01 but has not withdrawn such request pursuant to Section 10.02, in each case, in compliance with Applicable Procedures).

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

(c)    A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “ Conversion Date ”) that the Holder has complied with the requirements set forth in subsection (b) above. Subject to Section 9.03(b) and Section 9.07(a),

36

the Company shall pay or deliver, as the case may be, the Conversion Settlement Amount due in respect of the Conversion Obligation on:

(1)    if the Company elects Physical Settlement, on the third Business Day immediately following the relevant Conversion Date for any conversion occurring prior to the Regular Record Date immediately preceding the Maturity Date or on the Maturity Date, for any conversion occurring on or after the Regular Record Date immediately preceding the Maturity Date; or

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

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

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

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

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

(g)    Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s delivery of the Conversion Settlement Amount with respect to any converted Note shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if

37

any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, but prior to the open of business on the immediately following Interest Payment Date, Holders of such Notes as of the close of business on such Regular Record Date shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted (regardless of whether the converting Holder was a Holder of such Notes on the Regular Record Date); provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Purchase 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, if any overdue interest exists at the time of conversion with respect to such Note. For the avoidance of doubt, all Holders of Notes on the Regular Record Date immediately preceding the Maturity Date shall receive and retain the full interest payment due on the Maturity Date regardless of whether such Holders’ Notes are converted following such Regular Record Date.

(h)    The Person in whose name any shares of Common Stock shall be issuable upon conversion shall be treated as the holder of record of such shares as of the close of business on (i) the relevant Conversion Date if the Company elects Physical Settlement or (ii) the last VWAP Trading Day of the applicable Observation Period if the Company elects or is deemed to elect Combination Settlement. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion; provided that (a) the converting Holder shall have the right to receive the Conversion Settlement Amount due upon conversion and (b) in the case of a conversion between a Regular Record Date and the corresponding Interest Payment Date, the Holder of record as of the close of business on such Regular Record Date shall have the right to receive the full amount of interest payable on such Interest Payment Date, in accordance with Section 9.02(g).

(i)    The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion 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 applicable Observation Period if the Company elects or is deemed to elect Combination Settlement.

Section 9.03     Increased Conversion Rate Applicable to Certain Notes Surrendered for Conversion in Connection with Make-Whole Fundamental Changes. (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder of the Notes elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “ Additional Shares ”), as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion (or, with respect to Global Notes, the relevant notice of conversion in

38

accordance with Applicable Procedures) is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to the close of business on the Business Day immediately preceding the related Fundamental Change Purchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for subclause (A) of the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change).

(b)    Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall satisfy the related Conversion Obligation in accordance with Section 9.02; provided , however , that if the consideration received by holders of the Common Stock in exchange for such Common Stock in any Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the third Business Day following the Conversion Date.

The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent (if other than the Trustee) in accordance with Section 10.02 of the Base Indenture, of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date or publish the information on its website or through such other public medium as the Company may use at that time no later than five Business Days after such Effective Date.

(c)    The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table in Section 9.03(e), based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “ Effective Date ”) and the price (the “ Stock Price ”) paid (or deemed to be paid) per share of Common Stock in the Make-Whole Fundamental Change. If the holders of Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

(d)    The Stock Prices set forth in the column headings of the table in Section 9.03(e) shall be adjusted as of any date on which the Conversion Rate is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table in Section 9.03(e) shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 9.04.

39

(e)    The following table sets forth the number of Additional Shares to be added to the Conversion Rate per $1,000 principal amount of Notes pursuant to this Section 9.03:

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

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

(ii)    If the Stock Price is greater than $650.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to Section 9.03(d)), no Additional Shares shall be added to the Conversion Rate.

(iii)    If the Stock Price is less than $262.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to Section 9.03(d)), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 3.8167 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 9.04.

(f)    Nothing in this Section 9.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 9.04 in respect of a Make-Whole Fundamental Change.

Section 9.04     Adjustment of Conversion Rate . The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a share split or share combination), as a result of holding the Notes, and contemporaneously with the holders of the Common Stock, in any of the transactions described in this Section 9.04, as if such Holder of Notes held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder, without having to convert their Notes.

40

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

Any adjustment made under this Section 9.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 9.04(a) is declared but not so paid or made, or the outstanding shares of Common Stock are not so split or combined, as the case may be, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such share split or share combination, to the Conversion Rate that would then be in effect if such dividend or distribution or share split or share combination had not been declared.

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

41

where,

Any increase made under this Section 9.04(b) shall be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, or if no such rights, options or warrants are exercised prior to their expiration, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had not occurred.

For the purpose of this Section 9.04(b) and for the purpose of Section 9.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

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

(i)    dividends or distributions as to which an adjustment was effected pursuant to Section 9.04(a) or Section 9.04(b);

42

(ii)    dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 9.04(d);

(iii)    distributions of Reference Property in a transaction described in Section 9.07;

(iv)    except as described below, rights issued pursuant to a stockholder rights plan of the Company; and

(v)    Spin-Offs as to which the provisions set forth below in this Section 9.04(c) shall apply,

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

Any increase made under the portion of this Section 9.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock, without having to convert its Notes, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.

43

If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 9.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing “SP ₀ ”.

With respect to an adjustment pursuant to this Section 9.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “ Spin-Off ”), the Conversion Rate shall be increased based on the following formula:

where,

The adjustment to the Conversion Rate under the preceding paragraph shall be determined on the last Trading Day of the Valuation Period but shall be given effect at the open of business on the Ex-Dividend Date for such Spin-Off. Notwithstanding the foregoing, in respect of any conversion during the Valuation Period, references in the portion of this Section 9.04(c) related to Spin-Offs with respect to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and

44

the Conversion Date in determining the Conversion Rate. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion of Notes, references in the portion of this Section 9.04(c) related to Spin-Offs with respect to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period. If such Spin-Off does not occur, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared, effective as of the date on which the Board of Directors determines not to consummate such Spin-Off.

For purposes of this Section 9.04(c) (and subject in all respects to Section 9.11), rights, options or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including shares of Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“ Trigger Event ”):

(i)    are deemed to be transferred with such shares of 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 9.04(c) (and no adjustment to the Conversion Rate under this Section 9.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 9.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Supplemental Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 9.04(c) was made:

(1)    in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or

45

purchase 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 purchase; 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 and warrants had not been issued.

For purposes of Section 9.04(a), Section 9.04(b) and this Section 9.04(c), if any dividend or distribution to which this Section 9.04(c) is applicable also includes one or both of:

(A)     a dividend or distribution of shares of Common Stock to which Section 9.04(a) is applicable (the “ Clause A Distribution ”); or

(B)     a dividend or distribution of rights, options or warrants to which Section 9.04(b) is applicable (the “ Clause B Distribution ”),

then:

(1)    such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 9.04(c) is applicable (the “ Clause C Distribution ”) and any Conversion Rate adjustment required by this Section 9.04(c) with respect to such Clause C Distribution shall then be made; and

(2)    the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 9.04(a) and Section 9.04(b) with respect thereto shall then be made, except that, if determined by the Company:

(I)    the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution; and

(II)    any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 9.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 9.04(b).

(d)    If the Company pays any cash dividend or distribution to all or substantially all holders of the shares of Common Stock, the Conversion Rate shall be adjusted based on the following formula:

46

where,

Any increase to the Conversion Rate pursuant to this Section 9.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of Common Stock without having to convert its Notes, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution.

(e)    If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported 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 Conversion Rate shall be increased based on the following formula:

where,

47

The increase to the Conversion Rate under this Section 9.04(e) shall be determined at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date but shall be given effect at the open of business on the Trading Day next succeeding the Expiration Date. Notwithstanding the foregoing, in respect of any conversion within the 10 Trading Days immediately following, and including, the Trading Day next succeeding any Expiration Date, references in this Section 9.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between such Expiration Date and the Conversion Date in determining the Conversion Rate. In addition, if the Trading Day next succeeding the Expiration Date is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion of Notes, references in this Section 9.04(e) to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last Trading Day of such Observation Period. For the avoidance of doubt, no adjustment under this Section 9.04(e) shall be made if such adjustment would result in a decrease in the Conversion Rate.

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

(f)    Notwithstanding this Section 9.04 or any other provision of the Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 9.02(h) based on an adjusted Conversion

48

Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 9.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g)    Notwithstanding any other provision of the Indenture or the Notes, in no event will the Conversion Rate per $1,000 principal amount of the Notes exceed 3.8167 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate as set forth in this Section 9.04.

(h)    In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 9.04, and to the extent permitted by applicable law and subject to the applicable rules of the NASDAQ Global Select Market or any other securities exchange on which securities of the Company are then listed, (i) the Company may increase the Conversion Rate of the Notes by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest and (ii) the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the Holder of each Note at its last address appearing on the Note Register, the Trustee and the Conversion Agent (if other than the Trustee) a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i)    All calculations and other determinations under this Article 9 shall be made by the Company and all calculations of the Conversion Rate shall be made to the nearest one-ten thousandth (1/10,000th) of a share. No adjustment in the Conversion Rate shall be required unless such adjustment would require a change of at least 1% in the Conversion Rate; provided, however , that the Company shall carry forward any adjustments which would be required to be made but for this Section 9.04(i), take such carried-forward adjustments into account in any subsequent adjustment, and make such carried-forward adjustments, regardless of whether the aggregate adjustment is less than 1%, (x) annually on the anniversary of the date of original issuance of the Notes and (y) otherwise (1) upon conversion of any Notes or (2) prior to any Fundamental Change Purchase Date, unless such adjustment has already been made.

(j)    Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. 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 mail such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

49

(k)    For purposes of this Section 9.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 9.05     Adjustments of Prices . Whenever any provision of the Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and, if applicable, the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or Expiration Date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

Section 9.06     Shares To Be Fully Reserved . The Company shall reserve, out of its authorized but unissued shares that are not reserved for other purposes, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder of the Notes and that Physical Settlement is applicable, and including the maximum number of Additional Shares that could be included in the Conversion Rate for a conversion in connection with a Make-Whole Fundamental Change).

Section 9.07     Effect of Recapitalizations, Reclassifications and Changes of the Common Stock .

(a)    In the case of:

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

(ii)    any consolidation, merger, combination, statutory or binding share exchange or similar transaction involving the Company; or

(iii)    any sale, conveyance, lease or other transfer or similar transaction to a third party of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, cash, securities or other property or assets (any such event, a “ Share Exchange Event ,” and any such cash, securities or other property or assets, the “ Reference Property ,” and the amount of Reference Property that a holder of one share of Common Stock immediately prior to such Share Exchange Event would have been entitled to receive upon the occurrence of such Share

50

Exchange Event, a “ unit of Reference Property ”), then the Company or the successor or purchasing company, as the case may be, shall execute with the Trustee, without the consent of the Holders of Notes, a supplemental indenture providing that, at and after the effective time of such Share Exchange Event, a Holder’s right to convert a Note into cash and, if applicable, shares of Common Stock (unless the Company elects to deliver cash in lieu of all or a portion of such shares) shall be changed into a right to convert a Note into cash and, if applicable, units of Reference Property (unless the obligor elects to deliver cash in lieu of all or a portion of such units of Reference Property); provided, however, that at and after the effective time of the Share Exchange Event:

(A)    the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 9.02;

(B)    any amount payable in cash upon conversion of the Notes in accordance with Section 9.02 shall continue to be payable in cash;

(C)    any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 9.02 (subject to the Company’s right to elect to deliver cash in lieu of all or a portion of such shares) shall instead be deliverable in units of Reference Property (subject to the obligor’s right to elect to deliver cash in lieu of all or a portion of such units of Reference Property); and

(D)    the Daily VWAP shall be calculated based on the value of a unit of Reference Property;

provided, however, if the holders receive only cash in such Share Exchange Event, then for all conversions that occur after the effective date of such Share Exchange Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 9.03), multiplied by the price paid per share of Common Stock in such Share Exchange Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion Date.

Such supplemental indenture described above shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as possible to the adjustments provided for in this Article 9. If the Reference Property in respect of any Share Exchange Event includes shares of stock, securities or other property or assets of a company other than the Company or the successor or purchasing corporation, as the case may be, in such Share Exchange Event, then such other company shall also execute such supplemental indenture, and such supplemental indenture shall contain such additional provisions to protect the interests of the Holders of Notes, including the right of Holders of Notes to require the Company to purchase their Notes upon a Fundamental Change pursuant to Section 10.01, as the Board of Directors reasonably considers necessary by reason of the foregoing.

51

If the Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then:

(i)    the amount and kind of Reference Property into which the Notes will be convertible shall be deemed to be (A) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (B) if no holders of the shares of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of Common Stock; and

(ii)    the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock.

The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

(b)    In the event the Company shall execute a supplemental indenture pursuant to Section 9.07(a), the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with. In addition, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) and issue a press release containing such information or publish such information on its website or through such other public medium as the Company may use. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the Note Register, within 20 Business Days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c)    The Company shall not become a party to any Share Exchange Event unless its terms are consistent with this Section 9.07. None of the foregoing provisions shall affect the right of a Holder of the Notes to convert its Notes into cash and, if applicable, shares of Common Stock (subject to the Company’s right to elect to deliver cash in lieu of all or a portion of such shares), as set forth in Section 9.01 and Section 9.02 prior to the effective date of such Share Exchange Event.

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

Section 9.08     Certain Covenants . (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes, if any, will be fully paid and non-assessable by the Company and free from preemptive rights and all taxes, liens and charges with respect to the issue thereof.

(b)    The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any

52

governmental authority under any federal or state law before such shares may be validly issued upon conversion (other than solely as a result of the status of the converting Holder as an affiliate of the Company), the Company will secure such registration or approval, as the case may be.

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

Section 9.09     Responsibility of Trustee . The Trustee and the Conversion Agent (if other than the Trustee) shall not at any time be under any duty or responsibility to any Holder to (i) perform any calculations or make any determinations under this Article 9 or (ii) determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and the Conversion Agent (if other than the Trustee) 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 the Conversion Agent (if other than the Trustee) make no representations with respect thereto. Neither the Trustee nor the Conversion Agent (if other than the Trustee) shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor the Conversion Agent (if other than the Trustee) shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 9.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 9.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.02 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent (if other than the Trustee) shall be responsible for determining whether any event contemplated by Section 9.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent (if other than the Trustee) the notices referred to in Section 9.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent (if other than the Trustee) may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent (if other than the Trustee) immediately after the occurrence of any such event or at such other times as shall be provided for in Section 9.01(b). The rights, benefits and privileges of the Trustee set forth in the Base Indenture shall be applicable to the Conversion Agent (if other than the Trustee), and the provisions set forth in Section 7.01(a), (b) and (c) of the Base Indenture relating to the Trustee shall apply to the Conversion Agent (if other than the Trustee).

53

Section 9.10     Notice to Holders Prior to Certain Actions . In case of any:

(a)    action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 9.04 or Section 9.11;

(b)    Share Exchange Event; or

(c)    voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries;

then, in each case (unless notice of such event is otherwise required pursuant to another provision of the Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Note Register, concurrently with the public disclosure thereof, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Share Exchange Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Share Exchange Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Share Exchange Event, dissolution, liquidation or winding-up.

Section 9.11     Stockholder Rights Plans . If the Company has a rights plan in effect upon conversion of the Notes into Common Stock, if any, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and any certificate representing the share of Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time. If however, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock Distributed Property as provided in Section 9.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 9.12     No Adjustments . (a) Except as provided in Section 9.02, the Conversion Rate shall not be adjusted for the issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or the right to purchase Common Stock or any such convertible or exchangeable security, and, for the avoidance of doubt, no adjustment in the Conversion Rate shall be required:

54

(b)    To the extent that the Securities become convertible into the right to receive only cash in accordance with the provision of Section 9.07, no adjustment need be made thereafter as to the amount of cash to be received.

Section 9.13     Exchange in Lieu of Conversion .

(a)    When a Holder surrenders its Notes for conversion, the Company may, at its election, direct the Conversion Agent to surrender, on or prior to the second 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 9.02 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 on the second Business Day following the relevant Conversion Date, notify the Holder surrendering Notes for conversion that it has made such election. In addition, the Company shall concurrently notify the Designated Institution of 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 Conversion Agent, or if the Designated Institution does not accept such Notes for exchange, the Company shall, within the time period specified in Section 9.02(c), 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 9.02.

55

(c)    For the avoidance of doubt, in no event will the Company’s designation of a Designated Institution pursuant to this Section 9.13 require the Designated Institution to accept any Notes for exchange.

ARTICLE 10

REPURCHASE OF NOTES AT OPTION OF HOLDERS

Section 10.01     Purchase at Option of Holders Upon a Fundamental Change . (a) If a Fundamental Change occurs at any time, each Holder of the Notes shall have the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Notes, or any portion of the principal thereof that is equal to $1,000 principal amount or an integral multiple of $1,000 principal amount, on the date (the “ Fundamental Change Purchase Date ”) specified by the Company that is not less than 20 nor more than 35 Business Days following the date of the Fundamental Change Company Notice (or, if the Company fails to specify a Fundamental Change Purchase Date, the 35th Business Day following the date of the Fundamental Change Company Notice, without prejudice to any rights or remedies Holders may have on account of such failure) at a purchase price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest to, but not including, the Fundamental Change Purchase Date (the “ Fundamental Change Purchase Price ”); provided that if the Fundamental Change Purchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, then the Company shall instead pay the full amount of accrued and unpaid interest to the Holder of record on such Regular Record Date, and the Fundamental Change Purchase Price shall be equal to 100% of the principal amount of Notes to be purchased pursuant to this Article 10.

(b)    Purchases of Notes under this Section 10.01 shall be made, at the option of the Holder thereof, upon:

(i)    delivery to the Paying Agent (and the Trustee, if not the Paying Agent) by a Holder of a duly completed notice (the “ Fundamental Change Purchase Notice ”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Applicable Procedures, if the Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date; and

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

56

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

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

(ii)    the portion of the principal amount of Notes to be purchased, which must be $1,000 or an integral multiple thereof; and

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

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

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 10.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 10.02.

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

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

57

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

(x)    any other information that the Company shall reasonably determine is appropriate to include therein.

Notwithstanding the foregoing, the Company will not be required to repurchase, or to make an offer to repurchase, the Notes upon a Fundamental Change if a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth above and such third party purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth above.

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

Such notice shall be by first class mail to the Trustee, to the Paying Agent and to each Holder of the Notes at its address shown in the Note Register (and to beneficial owners as required by applicable law) or, in the case of Global Notes, in accordance with Applicable Procedures. Simultaneously with providing such notice, the Company shall issue a press release and publish a notice containing the information set forth in the Fundamental Change Company Notice on the Company’s website or through such other public medium as the Company may use at that time.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 10.01.

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

Section 10.02     Withdrawal of Fundamental Change Purchase Notice . A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 10.02 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date, specifying:

(i)    the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, which must be $1,000 aggregate principal amount or an integral multiple thereof;

58

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

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

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

Section 10.03     Deposit of Fundamental Change Purchase Price . (a) The Company shall deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 2.05 of the Base Indenture) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Purchase Date an amount of money sufficient to purchase all of the Notes to be purchased at the appropriate Fundamental Change Purchase Price. Subject to receipt of funds by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for purchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date) will be made on the later of (i) the Fundamental Change Purchase Date (provided that the Holder has satisfied the conditions in Section 10.01) and (ii) the time of book-entry transfer or the delivery of such Notes to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 10.01, by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided , however , that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Purchase Price.

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

(i)    such Notes shall cease to be outstanding and interest shall cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent); and

(ii)    all other rights of the Holders of such Notes shall terminate (other than (x) the right to receive the Fundamental Change Purchase Price and (y) if the Fundamental Change Purchase Date falls after a Regular Record Date but on or prior to the related Interest Payment Date, the right of the Holder of record on such Regular Record Date to receive the related interest payment).

59

(c)    Upon surrender of a Note that is to be purchased in part pursuant to Section 10.01, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unpurchased portion of the Note surrendered, without payment of any service charge.

Section 10.04     Covenant to Comply with Applicable Laws Upon Purchase of Notes . In connection with any purchase offer pursuant to a Fundamental Change Company Notice, the Company shall, if required:

(a)    comply with the provisions of the tender offer rules under the Exchange Act that may then be applicable;

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

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

[FORM OF REVERSE OF NOTE]

TESLA, INC.

2.375% Convertible Senior Note due 2022

This Note is one of a duly authorized issue of Securities of the Company, designated as its 2.375% Convertible Senior Notes due 2022 (the “ Notes ”), limited to the aggregate principal amount of $850,000,000 (or $977,500,000 if the Underwriters exercise their option to purchase additional Notes in full in accordance with the Underwriting Agreement) all issued or to be issued under and pursuant to an Indenture dated as of May 22, 2013 (the “ Base Indenture ”), as amended and supplemented by the Fourth Supplemental Indenture dated as of March 22, 2017 (herein called the “ Supplemental Indenture ”; the Base Indenture, as amended and supplemented by the Supplemental Indenture, and as it may be further amended or supplemented from time to time, the “ Indenture ”), by and between the Company and U.S. Bank National Association (the “ Trustee ”) to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture.

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

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

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

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

A-4

applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate or in the amount, as applicable, and in the manner herein prescribed.

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

The Notes shall not be redeemable at the Company’s option.

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

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

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