Item 1.01 Entry into a Material Definitive Agreement

Notes and the Indenture

On February 14, 2014, AMAG Pharmaceuticals, Inc. (the “ Company ”) completed its previously announced public offering (the “ Offering ”) of $200 million aggregate principal amount of the Company’s 2.50% Convertible Senior Notes due 2019 (the “ Notes ”), which includes $25 million principal amount of Notes issued pursuant to the full exercise of the over-allotment granted to the underwriters in the offering. The net proceeds from the sale of the Notes were approximately $193.3 million after deducting the underwriters’ discounts and commissions and the estimated offering expenses payable by the Company. The Company used $14.1 million of the net proceeds from the sale of the Notes to pay the cost of the Bond Hedges described below (after such cost was partially offset by the proceeds to the Company from the sale of Warrants in the warrant transactions described below), and the Company intends to use the remainder of the net proceeds from the sale of the Notes for working capital and other general corporate purposes, including to fund possible acquisitions of, or investments in, complementary businesses, products, services and technologies. The Company has not entered into any agreements or commitments with respect to any acquisitions or investments at this time.

The Notes are governed by the terms of a base indenture for senior debt securities (the “ Base Indenture ”) as supplemented by the first supplemental indenture thereto (the “ Supplemental Indenture ” and together with the Base Indenture, the “ Indenture ”), each dated as of February 14, 2014 and between the Company and Wilmington Trust, National Association, as trustee (the “ Trustee ”). The Notes are the senior unsecured obligations of the Company and bear interest at a rate of 2.50% per annum, payable semi-annually in arrears on February 15 and August 15 of each year, beginning on August 15, 2014. The Notes will mature on February 15, 2019, unless earlier repurchased or converted. The Notes will be convertible into cash, shares of the Company’s common stock, par value $0.01 per share (the “ Common Stock ”), or a combination thereof, at the Company’s election, at an initial conversion rate of 36.9079 shares of Common Stock per $1,000 principal amount of the Notes, which corresponds to an initial conversion price of approximately $27.09 per share of Common Stock and represents a conversion premium of approximately 35% based on the last reported sale price of the Common Stock of $20.07 on February 11, 2014, the date the Notes Offering was priced.

The conversion rate is subject to adjustment from time to time upon the occurrence of certain events, including, but not limited to, the issuance of stock dividends and payment of cash dividends. At any time prior to the close of business on the business day immediately preceding May 15, 2018, holders may convert their Notes at their option only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2014 (and only during such calendar quarter), if the last reported sale price of the Common Stock for at least 20 trading days (whether or not consecutive) during a 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; (2) during the five business day period after any five consecutive trading day period (the “ measurement period ”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Common Stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On or after May 15, 2018 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. If a make-whole fundamental change, as described in the Indenture, occurs and a holder elects to convert its Notes in connection with such make-whole fundamental change, such holder may be entitled to an increase in the conversion rate as described in the Indenture.

The Company may not redeem the Notes prior to the maturity date and no “sinking fund” is provided for the Notes, which means that the Company is not required to periodically redeem or retire the Notes. Upon the occurrence of certain fundamental changes involving the Company, holders of the Notes may require the Company to repurchase for cash all or part of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest.

The Indenture does not contain any financial or maintenance covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by the Company or any of its subsidiaries. The Indenture contains customary terms and covenants and events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving the Company) occurs and is continuing, the Trustee by notice to the Company, or the holders of at least 25% in principal amount of the outstanding Notes by written notice to the Company and the Trustee, may declare 100% of the principal of and accrued and unpaid interest, if any, on all of the Notes to be due and payable. Upon such a declaration of acceleration, such principal and accrued and unpaid interest, if any, will be due and payable immediately. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company, 100% of the principal of and accrued and unpaid interest, if any, on all of the Notes will become due and payable automatically. Notwithstanding the foregoing, the Indenture provides that, to the extent the Company elects and for up to 270 days, the sole remedy for an event of default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right to receive additional interest on the Notes.

The foregoing description of the Indenture and the Notes does not purport to be complete and is qualified in its entirety by reference to the Base Indenture, Supplemental Indenture and form of Note filed hereto as Exhibit 4.1, Exhibit 4.2 and Exhibit 4.3, respectively, which are incorporated herein by reference.

Convertible Note Hedge and Warrant Transactions

In connection with the pricing of the Notes, on February 11, 2014, the Company entered into convertible note hedge transactions relating to a notional number of shares of the Company’s Common Stock underlying $175.0 million aggregate principal amount of the Notes (the “ Initial Bond Hedges ”) with JPMorgan Chase Bank, National Association, London Branch, Morgan Stanley & Co. International plc and Royal Bank of Canada (collectively, the “ Call Spread Counterparties ”). On February 11, 2014, the Company also entered into separate warrant transactions (the “Base Warrants ”) with each of the Call Spread Counterparties relating, in the aggregate, to a notional number of shares of the Company’s Common Stock underlying the $175.0 million aggregate principal amount of the Notes. On February 13, 2014, the Company entered into additional convertible note hedge transactions (the “ Additional Bond Hedges ” and together with the Initial Bond Hedges, the “ Bond Hedges ”) with the Call Spread Counterparties relating to the notional number of shares of the Company’s Common Stock underlying $25.0 million aggregate principal amount of Notes to be issued by the Company in connection with the underwriters’ exercise of their overallotment option in full. On February 13, 2014, the Company also entered into separate additional warrant transactions (the “ Additional Warrants ” and together with the Base Warrants, the “ Warrants ” and the Warrants together with the Bond Hedges, the “ Call Spread Transactions ”) with each of the Call Spread Counterparties relating, in the aggregate, to a notional number of shares of the Company’s Common Stock underlying the $25.0 million aggregate principal amount of additional Notes.

The Bond Hedges are expected generally to reduce the potential dilution to the Company’s Common Stock and/or offset cash payments due upon conversion of the Notes in the event that the market price per share of the Company’s Common Stock, as measured under the terms of the Bond Hedges, is greater than the strike price of the Bond Hedges (which corresponds to the initial conversion price of the Notes and is subject to certain adjustments substantially similar to those contained in the Notes). The Warrants would separately have a dilutive effect to the extent that the market value per share of the Company’s Common Stock, as measured under the terms of the Warrants, exceeds the applicable strike price of the Warrants. The initial strike price of the Warrants is $34.1190 per share, which is 70% above the last reported sale price of the Company’s Common Stock of $20.07 on February 11, 2014. The Warrants were issued to the Call Spread Counterparties pursuant to the exemption from registration set forth in Section 4(a)(2) of the Securities Act.

Aside from the initial payment of a premium to the Call Spread Counterparties under the Bond Hedges, which amount is partially offset by the receipt of a premium under the Warrants, the Company is not required to make any cash payments to the Call Spread Counterparties under the Bond Hedges and will not receive any proceeds if the Warrants are exercised.

The foregoing description of the Bond Hedges and Warrants is qualified in its entirety by reference to the call option transaction confirmations relating to the Bond Hedges and the warrant confirmations relating to the Warrants with each of the Call Spread Counterparties, which are filed hereto as Exhibits 10.1 through 10.12 and which are incorporated herein by reference.

Item 3.02. Unregistered Sales of Equity Securities

The information required by Item 3.02 is contained in Item 1.01 and is incorporated into this Item 3.02 by reference.

Item 3.03 Material Modification to Rights of Security Holders

In connection with the pricing of Notes in the Offering, on February 11, 2014, the Company and American Stock Transfer & Trust Company, LLC (the “ Rights Agent ”) entered into an amendment (the “ Amendment ”) to the Rights Agreement, dated as of September 4, 2009, between the Company and the Rights Agent (the “ Rights Agreement ”). The Amendment, among other things, provides that, notwithstanding anything in the Rights Agreement to the contrary, each Call Spread Counterparty shall be deemed not to beneficially own any Common Shares underlying, or synthetically owned pursuant to, any Warrant held by such Call Spread Counterparty, any Common Shares held by such Call Spread Counterparty (or any affiliate thereof) to hedge its exposure with respect to the Call Spread Transactions, any Common Shares underlying, or synthetically owned pursuant to, any Derivative Securities (as such term is defined in the Rights Agreement), including the Notes, held, or entered into, by such Call Spread Counterparty (or any affiliate thereof) to hedge its exposure with respect to the Call Spread Transactions or any Notes held by such Call Spread Counterparty (or any affiliate thereof) in its capacity as underwriter of the Offering.

Section 2.03 Denominations: Provisions for Payment.

The Securities shall be issuable as registered Securities and in the denominations of one thousand U.S. dollars ($1,000) or any integral multiple thereof, subject to Section 2.01(a)(10). The Securities of a particular series shall bear interest payable on the dates and at the rate specified with respect to that series. Subject to Section 2.01(a)(16), the principal of and the interest on the Securities of any series, as well as any premium thereon in case of redemption thereof prior to maturity, shall be payable in the coin or currency of the United States of America that at the time is legal tender for public and private debt, at the office or agency of the Company maintained for that purpose. Each Security shall be dated the date of its authentication. Interest on the Securities shall be computed on the basis of a 360-day year composed of twelve 30-day months.

The interest installment on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date for Securities of that series shall be paid to the Person in whose name said Security (or one or more Predecessor Securities) is registered at the close of business on the regular record date for such interest installment. In the event that any Security of a particular series or portion thereof is called for redemption and the redemption date is subsequent to a regular record date with respect to any Interest Payment Date and prior to such Interest Payment Date, interest on such Security will be paid upon presentation and surrender of such Security as provided in Section 3.03.

Any interest on any Security that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date for Securities of the same series (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered holder on the relevant regular record date by virtue of having been such holder; and such Defaulted Interest shall be paid by the Company, at its election, as provided in clause (1) or clause (2) below:

(1) The Company may elect to make payment of any Defaulted Interest on Securities to the Persons in whose names such Securities (or their respective Predecessor Securities) are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner: the Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Interest which shall not be more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee in writing of such special record date and in such notice, instruct the Trustee to send such notice to Holders and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be sent electronically mailed, first class postage prepaid, to each Securityholder at his or her address as it appears in the Security Register (as hereinafter defined), not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been sent as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names such Securities (or their respective Predecessor Securities) are registered on such special record date.

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

Unless otherwise set forth in a Board Resolution or one or more indentures supplemental hereto establishing the terms of any series of Securities pursuant to Section 2.01 hereof, the term “regular record date” as used in this Section with respect to a series of Securities and any Interest Payment Date for such series shall mean either the fifteenth day of the month immediately preceding the month in which an Interest Payment Date established for such series pursuant to Section 2.01 hereof shall occur, if such Interest Payment Date is the first day of a month, or the first day of the month in which an Interest Payment Date established for such series pursuant to

Section 2.01 hereof shall occur, if such Interest Payment Date is the fifteenth day of a month, whether or not such date is a Business Day.

Subject to the foregoing provisions of this Section, each Security of a series delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Security of such series shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other Security.

Section 2.04 Execution and Authentications.

The Securities shall be signed on behalf of the Company by one of its Officers. Signatures may be in the form of a manual or facsimile signature.

The Company may use the facsimile signature of any Person who shall have been an Officer, notwithstanding the fact that at the time the Securities shall be authenticated and delivered or disposed of such Person shall have ceased to be such an officer of the Company. The Securities may contain such notations, legends or endorsements required by law, stock exchange rule or usage. Each Security shall be dated the date of its authentication by the Trustee.

A Security shall not be valid until authenticated manually by an authorized signatory of the Trustee, or by an Authenticating Agent. Such signature shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order of the Company for the authentication and delivery of such Securities, signed by an Officer, and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities.

In authenticating such Securities and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall receive, and (subject to Section 7.01) shall be fully protected in conclusively relying upon, an Opinion of Counsel stating that the form and terms thereof have been established in conformity with the provisions of this Indenture.

The Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee.

Section 2.05 Registration of Transfer and Exchange.

(a) Securities of any series may be exchanged upon presentation thereof at the office or agency of the Company designated for such purpose, for other Securities of such series of authorized denominations, and for a like aggregate principal amount, upon payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, all as provided in this Section. In respect of any Securities so surrendered for exchange, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in exchange therefor the Security or Securities of the same series that the Securityholder making the exchange shall be entitled to receive, bearing numbers not contemporaneously outstanding.

(b) The Company shall keep, or cause to be kept, at its office or agency designated for such purpose a register or registers (herein referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall register the Securities and the transfers of Securities as in this Article provided and which at all reasonable times shall be open for inspection by the Trustee. The registrar for the purpose of registering Securities and transfer of Securities as herein provided shall be appointed as authorized by Board Resolution (the “Security Registrar”).

Upon surrender for transfer of any Security at the office or agency of the Company designated for such purpose, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in the name of the transferee or transferees a new Security or Securities of the same series as the Security presented for a like aggregate principal amount.

All Securities presented or surrendered for exchange or registration of transfer, as provided in this Section, shall be accompanied (if so required by the Company or the Security Registrar) by a written instrument or instruments of transfer, in form satisfactory to the Company or the Security Registrar, duly executed by the registered holder or by such holder’s duly authorized attorney in writing.

(c) Except as provided pursuant to Section 2.01 pursuant to a Board Resolution, and set forth in an Officer’s Certificate, or established in one or more indentures supplemental to this Indenture, no service charge shall be made for any exchange or registration of transfer of Securities, or issue of new Securities in case of partial redemption of any series, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, other than exchanges pursuant to Section 2.06, Section 3.03(b) and Section 9.04 not involving any transfer.

(d) The Company shall not be required (i) to issue, exchange or register the transfer of any Securities during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of less than all the Outstanding Securities of the same series and ending at the close of business on the day of such mailing, nor (ii) to register the transfer of or exchange any Securities of any series or portions thereof called for redemption, other than the unredeemed portion of any such Securities being redeemed in part. The provisions of this Section 2.05 are, with respect to any Global Security, subject to Section 2.11 hereof.

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

Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by the Depositary.

Section 2.06 Temporary Securities.

Pending the preparation of definitive Securities of any series, the Company may execute, and the Trustee shall, upon Company Order, authenticate and deliver, temporary Securities (printed, lithographed or typewritten) of any authorized denomination. Such temporary Securities shall be substantially in the form of the definitive Securities in lieu of which they are issued, but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every temporary Security of any series shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities of such series. Without unnecessary delay the Company will execute and will furnish definitive Securities of such series and thereupon any or all temporary Securities of such series may be surrendered in exchange therefor (without charge to the holders), at the office or agency of the Company designated for the purpose, and the Trustee shall authenticate and such office or agency shall deliver in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities of such series, unless the Company advises the Trustee to the effect that definitive Securities need not be executed and furnished until further notice from the Company. Until so exchanged, the temporary Securities of such series shall be entitled to the same benefits under this Indenture as definitive Securities of such series authenticated and delivered hereunder.

Section 2.07 Mutilated, Destroyed, Lost or Stolen Securities.

In case any temporary or definitive Security shall become mutilated or be destroyed, lost or stolen, the Company (subject to the next succeeding sentence) shall execute, and upon receipt of a Company Order the Trustee (subject as aforesaid) shall authenticate and deliver, a new Security of the same series, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed, lost or stolen. In every case the applicant for a substituted Security shall furnish to the Company and the Trustee such security or indemnity as may be required by them to save each of them

harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee evidence to their satisfaction of the destruction, loss or theft of the applicant’s Security and of the ownership thereof. The Trustee may authenticate any such substituted Security and deliver the same upon receipt of a Company Order. Upon the issuance of any substituted Security, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

In case any Security that has matured or is about to mature shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Security) if the applicant for such payment shall furnish to the Company and the Trustee such security or indemnity as they may require to save them harmless, and, in case of destruction, loss or theft, evidence to the satisfaction of the Company and the Trustee of the destruction, loss or theft of such Security and of the ownership thereof.

Every replacement Security issued pursuant to the provisions of this Section shall constitute an additional contractual obligation of the Company whether or not the mutilated, destroyed, lost or stolen Security shall be found at any time, or be enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of the same series duly issued hereunder. All Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities, and shall preclude (to the extent lawful) any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

Section 2.08 Cancellation.

All Securities surrendered for the purpose of payment, redemption, exchange or registration of transfer shall, if surrendered to the Company or any paying agent, be delivered to the Trustee for cancellation, or, if surrendered to the Trustee, shall be cancelled by it, and no Securities shall be issued in lieu thereof except as expressly required or permitted by any of the provisions of this Indenture. On written request of the Company at the time of such surrender, the Trustee shall deliver to the Company a certificate of cancellation for such canceled Securities held by the Trustee. The Trustee shall cancel and dispose of canceled Securities in accordance with its standard procedures. If the Company shall otherwise acquire any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation.

Section 2.09 Benefits of Indenture.

Nothing in this Indenture or in the Securities, express or implied, shall give or be construed to give to any Person, other than the parties hereto and the holders of the Securities any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein contained; all such covenants, conditions and provisions being for the sole benefit of the parties hereto and of the holders of the Securities.

Section 2.10 Authenticating Agent.

So long as any of the Securities of any series remain Outstanding there may be an Authenticating Agent for any or all such series of Securities which the Trustee shall have the right to appoint. Said Authenticating Agent shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, transfer or partial redemption thereof, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. All references in this Indenture to the authentication of Securities by the Trustee shall be deemed to include authentication by an Authenticating Agent for such series. Each Authenticating Agent shall be acceptable to the Company and shall be a corporation that has a combined capital and surplus, as most recently reported or determined by it, sufficient under the laws of any jurisdiction under which it is organized or in which it is doing business to conduct a trust business, and that is otherwise authorized under such laws to conduct such business and is subject to supervision or

examination by federal or state authorities. If at any time any Authenticating Agent shall cease to be eligible in accordance with these provisions, it shall resign immediately.

Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time (and upon request by the Company shall) terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon resignation, termination or cessation of eligibility of any Authenticating Agent, the Trustee may appoint an eligible successor Authenticating Agent acceptable to the Company. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder as if originally named as an Authenticating Agent pursuant hereto.

Section 2.11 Global Securities.

(a) If the Company shall establish pursuant to Section 2.01 that the Securities of a particular series are to be issued as a Global Security, then the Company shall execute and the Trustee shall, in accordance with Section 2.04, authenticate and deliver, a Global Security that (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, all of the Outstanding Securities of such series, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction and (iv) shall bear a legend substantially to the following effect: “Except as otherwise provided in Section 2.11 of the Indenture, this Security may be transferred, in whole but not in part, only to another nominee of the Depositary or to a successor Depositary or to a nominee of such successor Depositary.”

(b) Notwithstanding the provisions of Section 2.05, the Global Security of a series may be transferred, in whole but not in part and in the manner provided in Section 2.05, only to another nominee of the Depositary for such series, or to a successor Depositary for such series selected or approved by the Company or to a nominee of such successor Depositary.

(c) If at any time the Depositary for a series of the Securities notifies the Company that it is unwilling or unable to continue as Depositary for such series or if at any time the Depositary for such series shall no longer be registered or in good standing under the Exchange Act, or other applicable statute or regulation, and a successor Depositary for such series is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such condition, as the case may be, or if an Event of Default has occurred and is continuing and the Company has received a request from the Depositary or from the Trustee, this Section 2.11 shall no longer be applicable to the Securities of such series and the Company will execute, and subject to Section 2.04, the Trustee will authenticate and deliver the Securities of such series in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Security of such series in exchange for such Global Security. In addition, the Company may at any time determine that the Securities of any series shall no longer be represented by a Global Security and that the provisions of this Section 2.11 shall no longer apply to the Securities of such series. In such event the Company will execute and, subject to Section 2.04, the Trustee, upon receipt of an Officer’s Certificate evidencing such determination by the Company, will authenticate and deliver the Securities of such series in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Security of such series in exchange for such Global Security. Upon the exchange of the Global Security for such Securities in definitive registered form without coupons, in authorized denominations, the Global Security shall be canceled by the Trustee. Such Securities in definitive registered form issued in exchange for the Global Security pursuant to this Section 2.11(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such Securities to the Depositary for delivery to the Persons in whose names such Securities are so registered.

ARTICLE 3

REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS

Section 3.01 Redemption.

The Company may redeem the Securities of any series issued hereunder on and after the dates and in accordance with the terms established for such series pursuant to Section 2.01 hereof.

Section 3.02 Notice of Redemption.

(a) In case the Company shall desire to exercise such right to redeem all or, as the case may be, a portion of the Securities of any series in accordance with any right the Company reserved for itself to do so pursuant to Section 2.01 hereof, the Company shall, or shall cause the Trustee to, give notice of such redemption to holders of the Securities of such series to be redeemed by mailing, electronically or by first class postage prepaid mail, a notice of such redemption not less than 30 days and not more than 90 days before the date fixed for redemption of that series to such holders at their last addresses as they shall appear upon the Security Register, unless a shorter period is specified in the Securities to be redeemed. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the registered holder receives the notice. In any case, failure duly to give such notice to the holder of any Security of any series designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the redemption of any other Securities of such series or any other series. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with any such restriction.

Each such notice of redemption shall specify the date fixed for redemption and the redemption price at which Securities of that series are to be redeemed, and shall state that payment of the redemption price of such Securities to be redeemed will be made at the office or agency of the Company, upon presentation and surrender of such Securities, that interest accrued to the date fixed for redemption will be paid as specified in said notice, that from and after said date interest will cease to accrue and that the redemption is from a sinking fund, if such is the case. If less than all the Securities of a series are to be redeemed, the notice to the holders of Securities of that series to be redeemed in part shall specify the particular Securities to be so redeemed.

In case any Security is to be redeemed in part only, the notice that relates to such Security shall state the portion of the principal amount thereof to be redeemed, and shall state that on and after the redemption date, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued.

(b) If less than all the Securities of a series are to be redeemed, the Company shall give the Trustee at least 45 days’ notice (unless a shorter notice shall be satisfactory to the Trustee) in advance of the date fixed for redemption as to the aggregate principal amount of Securities of the series to be redeemed, and thereupon the Trustee shall select, by lot or in such other manner as it shall deem appropriate and fair in its discretion and that may provide for the selection of a portion or portions (equal to one thousand U.S. dollars ($1,000) or any integral multiple thereof) of the principal amount of such Securities of a denomination larger than $1,000, the Securities to be redeemed and shall thereafter promptly notify the Company in writing of the numbers of the Securities to be redeemed, in whole or in part. The Company may, if and whenever it shall so elect, by delivery of instructions signed on its behalf by an Officer, instruct the Trustee or any paying agent to call all or any part of the Securities of a particular series for redemption and to give notice of redemption in the manner set forth in this Section, such notice to be in the name of the Company or its own name as the Trustee or such paying agent may deem advisable. In any case in which notice of redemption is to be given by the Trustee or any such paying agent, the Company shall deliver or cause to be delivered to, or permit to remain with, the Trustee or such paying agent, as the case may be, such Security Register, transfer books or other records, or suitable copies or extracts therefrom, sufficient to enable the Trustee or such paying agent to give any notice by mail that may be required under the provisions of this Section.

Section 3.03 Payment Upon Redemption.

(a) If the giving of notice of redemption shall have been completed as above provided, the Securities or portions of Securities of the series to be redeemed specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to the date fixed for redemption and interest on such Securities or portions of Securities shall cease to accrue on and after the date fixed for redemption, unless the Company shall default in the payment of such redemption price and accrued interest with respect to any such Security or portion thereof. On presentation and surrender of such Securities on or after the date fixed for redemption at the place of payment specified in the notice, said Securities shall be paid and redeemed at the applicable redemption price for such series, together with interest accrued thereon to the date fixed for redemption (but if the date fixed for redemption is an interest payment date, the interest installment payable on such date shall be payable to the registered holder at the close of business on the applicable record date pursuant to Section 2.03).

(b) Upon presentation of any physical Security of such series that is to be redeemed in part only, the Company shall execute and the Trustee shall authenticate and the office or agency where the Security is presented shall deliver to the holder thereof, at the expense of the Company, a new Security of the same series of authorized denominations in principal amount equal to the unredeemed portion of the Security so presented.

Section 3.04 Sinking Fund.

The provisions of Sections 3.04, 3.05 and 3.06 shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise specified as contemplated by Section 2.01 for Securities of such series.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 3.05. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

Section 3.05 Satisfaction of Sinking Fund Payments with Securities.

The Company (i) may deliver Outstanding Securities of a series and (ii) may apply as a credit Securities of a series that have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series, provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the redemption price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

Section 3.06 Redemption of Securities for Sinking Fund.

Not less than 45 days prior to each sinking fund payment date for any series of Securities (unless a shorter period shall be satisfactory to the Trustee), the Company will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of the series, the portion thereof, if any, that is to be satisfied by delivering and crediting Securities of that series pursuant to Section 3.05 and the basis for such credit and will, together with such Officer’s Certificate, deliver to the Trustee any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 3.02 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 3.02. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 3.03.

Section 4.02 Maintenance of Office or Agency.

So long as any series of the Securities remain Outstanding, the Company agrees to maintain an office or agency with respect to each such series and at such other location or locations as may be designated as provided in this Section 4.02, where (i) Securities of that series may be presented for payment, (ii) Securities of that series may be presented as herein above authorized for registration of transfer and exchange, and (iii) notices and demands in respect of the Securities of that series and this Indenture may be given or served, such designation to continue with respect to such office or agency until the Company shall, by written notice in an Officer’s Certificate and delivered to the Trustee, designate some other office or agency for such purposes or any of them. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, notices and demands. The Company initially appoints the Corporate Trust Office of the Trustee as its paying agent with respect to the Securities.

Section 4.03 Paying Agents.

(a) If the Company shall appoint one or more paying agents for all or any series of the Securities, other than the Trustee, the Company will cause each such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section:

(1) that it will hold all sums held by it as such agent for the payment of the principal of (and premium, if any) or interest on the Securities of that series (whether such sums have been paid to it by the Company or by any other obligor of such Securities) in trust for the benefit of the Persons entitled thereto;

(2) that it will give the Trustee notice of any failure by the Company (or by any other obligor of such Securities) to make any payment of the principal of (and premium, if any) or interest on the Securities of that series when the same shall be due and payable;

(3) that it will, at any time during the continuance of any failure referred to in the preceding paragraph (a)(2) above, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent; and

(4) that it will perform all other duties of paying agent as set forth in this Indenture.

(b) If the Company shall act as its own paying agent with respect to any series of the Securities, it will on or before each due date of the principal of (and premium, if any) or interest on Securities of that series, set aside, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay such

principal (and premium, if any) or interest so becoming due on Securities of that series until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of such action, or any failure (by it or any other obligor on such Securities) to take such action. Whenever the Company shall have one or more paying agents for any series of Securities, it will, prior to each due date of the principal of (and premium, if any) or interest on any Securities of that series, deposit with the paying agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such paying agent is the Trustee) the Company will promptly notify the Trustee of this action or failure so to act.

(c) Notwithstanding anything in this Section to the contrary, (i) the agreement to hold sums in trust as provided in this Section is subject to the provisions of Section 11.05, and (ii) the Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or direct any paying agent to pay, to the Trustee all sums held in trust by the Company or such paying agent, such sums to be held by the Trustee upon the same terms and conditions as those upon which such sums were held by the Company or such paying agent; and, upon such payment by the Company or any paying agent to the Trustee, the Company or such paying agent shall be released from all further liability with respect to such money.

Section 4.04 Appointment to Fill Vacancy in Office of Trustee.

Section 5.02 Preservation Of Information; Communications With Securityholders.

(a) The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the holders of Securities contained in the most recent list furnished to it as provided in Section 5.01 and as to the names and addresses of holders of Securities received by the Trustee in its capacity as Security Registrar (if acting in such capacity).

(b) The Trustee may destroy any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

For the avoidance of doubt, a failure by the Company to file annual reports, information and other reports with the Commission within the time period prescribed thereof by the Commission shall not be deemed a breach of this Section 5.03.

(b) Delivery of reports, information and documents to the Trustee under Section 5.03 is for informational purposes only and the information and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information contained therein including the Company’s compliance with any of their covenants thereunder (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate).

Section 5.04 Reports by the Trustee.

The Company agrees to notify the Trustee in writing when any Securities become listed on any securities exchange or of any delisting thereof.

ARTICLE 6

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

Section 6.01 Events of Default.

(a) Whenever used herein with respect to Securities of a particular series, “Event of Default” means any one or more of the following events that has occurred and is continuing:

(1) the Company defaults in the payment of any installment of interest upon any of the Securities of that series, as and when the same shall become due and payable, and such default continues for a period of 90 days; provided, however, that a valid extension of an interest payment period by the Company in accordance with the terms of any indenture supplemental hereto shall not constitute a default in the payment of interest for this purpose;

(2) the Company defaults in the payment of the principal of (or premium, if any, on) any of the Securities of that series as and when the same shall become due and payable whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with respect to that series; provided, however, that a valid extension of the maturity of such Securities in accordance with the terms of any indenture supplemental hereto shall not constitute a default in the payment of principal or premium, if any;

(3) the Company fails to observe or perform any other of its covenants or agreements with respect to that series contained in this Indenture or otherwise established with respect to that series of Securities pursuant to Section 2.01 hereof (other than a covenant or agreement that has been expressly included in this Indenture solely for the benefit of one or more series of Securities other than such series) for a period of 90 days after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a “Notice of Default” hereunder, shall have been given to the Company by the Trustee, by registered or certified mail, or to the Company and the Trustee by the holders of at least 25% in principal amount of the Securities of that series at the time Outstanding;

(4) the Company pursuant to or within the meaning of any Bankruptcy Law (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property or (iv) makes a general assignment for the benefit of its creditors; or

(5) a court of competent jurisdiction enters an order under any Bankruptcy Law that (i) is for relief against the Company in an involuntary case, (ii) appoints a Custodian of the Company for all or substantially all of its property or (iii) orders the liquidation of the Company, and the order or decree remains unstayed and in effect for 90 days.

(b) In each and every such case (other than an Event of Default specified in clause (4) or clause (5) above), unless the principal of all the Securities of that series shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Securities of that series then Outstanding hereunder, by notice in writing to the Company (and to the Trustee if given by such Securityholders), may declare the principal of (and premium, if any, on) and accrued and unpaid interest on all the Securities of that series to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable. If an Event of Default specified in clause (4) or clause (5) above occurs, the principal of and accrued and unpaid interest on all the Securities of that series shall automatically be immediately due and payable without any declaration or other act on the part of the Trustee or the holders of the Securities.

(c) At any time after the principal of (and premium, if any, on) and accrued and unpaid interest on the Securities of that series shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the holders of a majority in aggregate principal amount of the Securities of that series then Outstanding hereunder, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (i) the Company has paid or deposited with the Trustee a sum sufficient to pay all matured installments of interest upon all the Securities of that series and the principal of (and premium, if any, on) any and all Securities of that series that shall have become due otherwise than by acceleration (with interest upon such principal and premium, if any, and, to the extent that such payment is enforceable under applicable law, upon overdue installments of interest, at the rate per annum expressed in the Securities of that series to the date of such payment or deposit) and the amount payable to the Trustee under Section 7.06, and (ii) any and all Events of Default under the Indenture with respect to such series, other than the nonpayment of principal on (and premium, if any, on) and accrued and unpaid interest on Securities of that series that shall not have become due by their terms, shall have been remedied or waived as provided in Section 6.06.

No such rescission and annulment shall extend to or shall affect any subsequent default or impair any right consequent thereon.

(d) In case the Trustee shall have proceeded to enforce any right with respect to Securities of that series under this Indenture and such proceedings shall have been discontinued or abandoned because of such

rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case, subject to any determination in such proceedings, the Company and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though no such proceedings had been taken.

Section 6.02 Collection of Indebtedness and Suits for Enforcement by Trustee.

(a) The Company covenants that (i) in case it shall default in the payment of any installment of interest on any of the Securities of a series, or in any payment required by any sinking or analogous fund established with respect to that series as and when the same shall have become due and payable, and such default shall have continued for a period of 90 days, or (ii) in case it shall default in the payment of the principal of (or premium, if any, on) any of the Securities of a series when the same shall have become due and payable, whether upon maturity of the Securities of a series or upon redemption or upon declaration or otherwise then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Securities of that series, the whole amount that then shall have been become due and payable on all such Securities for principal (and premium, if any) or interest, or both, as the case may be, with interest upon the overdue principal (and premium, if any) and (to the extent that payment of such interest is enforceable under applicable law) upon overdue installments of interest at the rate per annum expressed in the Securities of that series; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee under Section 7.06.

(b) If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or other obligor upon the Securities of that series and collect the moneys adjudged or decreed to be payable in the manner provided by law or equity out of the property of the Company or other obligor upon the Securities of that series, wherever situated.

(c) In case of any receivership, insolvency, liquidation, bankruptcy, reorganization, readjustment, arrangement, composition or judicial proceedings affecting the Company, or its creditors or property, the Trustee shall have power to intervene in such proceedings and take any action therein that may be permitted by the court and shall (except as may be otherwise provided by law) be entitled to file such proofs of claim and other papers and documents as may be necessary or advisable in order to have the claims of the Trustee and of the holders of Securities of such series allowed for the entire amount due and payable by the Company under the Indenture at the date of institution of such proceedings and for any additional amount that may become due and payable by the Company after such date, and to collect and receive any moneys or other property payable or deliverable on any such claim, and to distribute the same after the deduction of the amount payable to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of the holders of Securities of such series to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to such Securityholders, to pay to the Trustee any amount due it under Section 7.06.

(d) All rights of action and of asserting claims under this Indenture, or under any of the terms established with respect to Securities of that series, may be enforced by the Trustee without the possession of any of such Securities, 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 payment to the Trustee of any amounts due under Section 7.06, be for the ratable benefit of the holders of the Securities of such series.

In case of an Event of Default hereunder, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or 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 this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

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

Section 6.03 Application of Moneys Collected.

Any moneys collected by the Trustee pursuant to this Article with respect to a particular series of Securities shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal (or premium, if any) or interest, upon presentation of the Securities of that series, and notation thereon of the payment, if only partially paid, and upon surrender thereof if fully paid:

FIRST: To the payment of reasonable costs and expenses of collection and of all amounts payable to the Trustee and its agents under this Indenture;

SECOND: To the payment of the amounts then due and unpaid upon Securities of such series for principal (and premium, if any) and interest, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively; and

THIRD: To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto.

Section 6.04 Limitation on Suits.

No holder of any Security of any series shall have any right by virtue or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (i) such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof with respect to the Securities of such series specifying such Event of Default, as hereinbefore provided; (ii) the holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; (iii) such holder or holders shall have offered to the Trustee such indemnity reasonably satisfactory to it as it may require against the costs, expenses and liabilities to be incurred therein or thereby; (iv) the Trustee for 90 days after its receipt of such notice, request and offer of indemnity, shall have failed to institute any such action, suit or proceeding and (v) during such 90 day period, the holders of a majority in principal amount of the Securities of that series do not give the Trustee a direction inconsistent with the request.

Notwithstanding anything contained herein to the contrary or any other provisions of this Indenture, the right of any holder of any Security to receive payment of the principal of (and premium, if any) and interest on such Security, as therein provided, on or after the respective due dates expressed in such Security (or in the case of redemption, on the redemption date), or to institute suit for the enforcement of any such payment on or after such respective dates or redemption date, shall not be impaired or affected without the consent of such holder and by accepting a Security hereunder it is expressly understood, intended and covenanted by the taker and holder of every Security of such series with every other such taker and holder and the Trustee, that no one or more holders of Securities of such series shall have any right in any manner whatsoever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of the holders of any other of such Securities, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders), except in the manner herein provided and for the equal, ratable and common benefit of all holders of Securities of such series. For the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 6.05 Rights and Remedies Cumulative; Delay or Omission Not Waiver.

(a) Except as otherwise provided in Section 2.07, all powers and remedies given by this Article to the Trustee or to the Securityholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any other powers and remedies available to the Trustee or the holders of the Securities, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture or otherwise established with respect to such Securities.

(b) No delay or omission of the Trustee or of any holder of any of the Securities to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or an acquiescence therein; and, subject to the provisions of Section 6.04, every power and remedy given by this Article or by law to the Trustee or the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Securityholders.

Section 6.06 Control by Securityholders.

The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding, determined in accordance with Section 8.04, 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 such series; provided, however, that such direction shall not be in conflict with any rule of law or with this Indenture or subject the Trustee in its sole discretion to personal liability. Subject to the provisions of Section 7.01, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall determine that the proceeding so directed, subject to the Trustee’s duties under the Trust Indenture Act, would involve the Trustee in personal liability or might be unduly prejudicial to the Securityholders not involved in the proceeding. The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding affected thereby, determined in accordance with Section 8.04, may on behalf of the holders of all of the Securities of such series waive any past default in the performance of any of the covenants contained herein or established pursuant to Section 2.01 with respect to such series and its consequences, except a default in the payment of the principal of, or premium, if any, or interest on, any of the Securities of that series as and when the same shall become due by the terms of such Securities otherwise than by acceleration (unless such default has been cured and a sum sufficient to pay all matured installments of interest and principal and any premium has been deposited with the Trustee (in accordance with Section 6.01(c)). Upon any such waiver, the default covered thereby shall be deemed to be cured for all purposes of this Indenture and the Company, the Trustee and the holders of the Securities of such series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 6.07 Undertaking to Pay Costs.

All parties to this Indenture agree, and each holder of any Securities by such holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, 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, 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; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder, or group of Securityholders, holding more than 10% in aggregate principal amount of the Outstanding Securities of any series, or to any suit instituted by any Securityholder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security of such series, on or after the respective due dates expressed in such Security or established pursuant to this Indenture.

(a) The Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a series and after the curing of all Events of Default with respect to the Securities of that series that may have occurred, shall undertake to perform with respect to the Securities of such series such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants shall be read into this Indenture against the Trustee. In case an Event of Default with respect to the Securities of a series has occurred (that has not been cured or waived), the Trustee shall exercise with respect to Securities of that series such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(b) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(i) prior to the occurrence of an Event of Default with respect to the Securities of a series and after the curing or waiving of all such Events of Default with respect to that series that may have occurred:

(A) the duties and obligations of the Trustee shall with respect to the Securities of such series be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable with respect to the Securities of such series except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(B) in the absence of bad faith on the part of the Trustee, the Trustee may with respect to the Securities of such series conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein);

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(iii) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture with respect to the Securities of that series; and

(iv) none of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal or financial liability in the performance of any of its duties or in the exercise of any of its rights or powers if there is reasonable ground for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Indenture or adequate indemnity against such risk is not reasonably assured to it.

Section 7.02 Certain Rights of Trustee.

Except as otherwise provided in Section 7.01:

(a) The Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, security or other paper or document or other evidence of indebtedness believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) Any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by a Board Resolution or an instrument signed in the name of the Company by any authorized Officer of the Company (unless other evidence in respect thereof is specifically prescribed herein);

(c) The Trustee may consult with counsel of its selection and the written advice of such counsel or, if requested, any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted hereunder in good faith and in reliance thereon;

(d) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities that may be incurred therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default with respect to a series of the Securities (that has not been cured or waived), to exercise with respect to Securities of that series such of the rights and powers vested in it by this Indenture, and to use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs;

(e) The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture;

(f) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, security, or other papers or documents or other evidence if indebtedness unless requested in writing so to do by the holders of not less than a majority in principal amount of the Outstanding Securities of the particular series affected thereby (determined as provided in Section 8.04); provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require indemnity reasonably satisfactory to it against such costs, expenses or liabilities as a condition to so proceeding. The reasonable expense of every such examination shall be paid by the Company or, if paid by the Trustee, shall be repaid by the Company upon demand;

(g) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

(h) In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances;

(i) In no event shall the Trustee be responsible or liable for special, punitive, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action;

(j) The permissive rights of the Trusttee enumerated herin shall not be construed as duties; and

(k) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

In addition, the Trustee shall not be deemed to have knowledge of any Default or Event of Default until a Responsible Officer of the Trustee shall have received written notification in the manner set forth in this Indenture, and such notice references the Securities and this Indenture or a Responsible Officer of the Trustee shall have obtained actual knowledge.

Section 7.03 Trustee Not Responsible for Recitals or Issuance or Securities.

(a) The recitals contained herein and in the Securities shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same.

(b) The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities.

(c) The Trustee shall not be accountable for the use or application by the Company of any of the Securities or of the proceeds of such Securities, or for the use or application of any moneys paid over by the Trustee in accordance with any provision of this Indenture or established pursuant to Section 2.01, or for the use or application of any moneys received by any paying agent other than the Trustee.

Section 7.04 May Hold Securities.

The Trustee or any paying agent or Security Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not Trustee, paying agent or Security Registrar.

Section 7.05 Moneys Held in Trust.

Subject to the provisions of Section 11.05, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any moneys received by it hereunder except such as it may agree in writing with the Company to pay thereon.

Section 7.06 Compensation and Reimbursement.

(a) The Company covenants and agrees to pay to the Trustee, and the Trustee shall be entitled to, such compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as the Company and the Trustee may from time to time agree in writing, for all services rendered by it in the execution of the trusts hereby created and in the exercise and performance of any of the powers and duties hereunder of the Trustee, and, except as otherwise expressly provided herein, the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable fees and the expenses and disbursements of its counsel and of all Persons not regularly in its employ), except any such expense, disbursement or advance as may arise from its negligence or bad faith and except as the Company and Trustee may from time to time agree in writing. The Company also covenants to indemnify the Trustee (and its officers, agents, directors and employees) for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on the part of the Trustee and arising out of or in connection with the acceptance or

administration of this trust, including the reasonable costs and expenses of defending itself against any claim of liability in the premises (whether asserted by the Company, or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section.

(b) The obligations of the Company under this Section to compensate and indemnify the Trustee and to pay or reimburse the Trustee for reasonable expenses, disbursements and advances shall constitute additional indebtedness hereunder. Such additional indebtedness shall be secured by a lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the holders of particular Securities.

(c) To ensure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all funds or property held or collected by the Trustee, except that held in trust to pay principal of or interest on particular Securities. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(a)(4) or (5), the expenses (including the reasonable fees and expenses of its counsel) and the compensation for services in connection therewith are to constitute expenses of administration under any bankruptcy law. The provisions of this Section 7.06 shall survive the termination of this Indenture and the resignation or removal of the Trustee.

Section 7.07 Reliance on Officer’s Certificate.

Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it reasonably necessary or desirable that a matter be proved or established prior to taking or suffering or omitting to take any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the Trustee and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted to be taken by it under the provisions of this Indenture upon the faith thereof.

Section 7.08 Disqualification; Conflicting Interests.

If the Trustee has or shall acquire any “conflicting interest” within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the Company shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act.

Section 7.09 Corporate Trustee Required; Eligibility.

There shall at all times be a Trustee with respect to the Securities issued hereunder which shall at all times be a corporation organized and doing business under the laws of the United States of America or any state or territory thereof or of the District of Columbia, or a corporation or other Person permitted to act as trustee by the Commission, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least fifty million U.S. dollars ($50,000,000), and subject to supervision or examination by federal, state, territorial, or District of Columbia authority.

If such corporation or other Person publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation or other Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Company may not, nor may any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall resign immediately in the manner and with the effect specified in Section 7.10.

Section 7.10 Resignation and Removal; Appointment of Successor.

(a) The Trustee or any successor hereafter appointed may at any time resign with respect to the Securities of one or more series by giving written notice thereof to the Company and by transmitting notice of

resignation by electronic mail, or by first class postage prepaid mail, to the Securityholders of such series, as their names and addresses appear upon the Security Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee with respect to Securities of such series by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee with respect to Securities of such series, or any Securityholder of that series who has been a bona fide holder of a Security or Securities for at least six months may on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any one of the following shall occur:

(i) the Trustee shall fail to comply with the provisions of Section 7.08 after written request therefor by the Company or by any Securityholder who has been a bona fide holder of a Security or Securities for at least six months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.09 and shall fail to resign after written request therefor by the Company or by any such Securityholder; or

(iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding, or a receiver of the Trustee or of its property shall be appointed or consented to, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee with respect to all Securities and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or any Securityholder who has been a bona fide holder of a Security or Securities for at least six months may, on behalf of that holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c) The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding may at any time remove the Trustee with respect to such series by so notifying the Trustee and the Company and may appoint a successor Trustee for such series with the consent of the Company.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee with respect to the Securities of a series pursuant to any of the provisions of this Section shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11.

(e) Any successor trustee appointed pursuant to this Section may be appointed with respect to the Securities of one or more series or all of such series, and at any time there shall be only one Trustee with respect to the Securities of any particular series.

Section 7.11 Acceptance of Appointment By Successor.

(a) In case of the appointment hereunder of a successor trustee with respect to all Securities, every such successor trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor trustee, such retiring Trustee shall, upon full payment of any amount then due it pursuant to Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights, powers, and trusts of the

retiring Trustee and shall duly assign, transfer and deliver to such successor trustee all property and money held by such retiring Trustee hereunder.

(b) In case of the appointment hereunder of a successor trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor trustee relates, (ii) shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and that no Trustee shall be responsible for any act or failure to act on the part of any other Trustee hereunder; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall with respect to the Securities of that or those series to which the appointment of such successor trustee relates have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture, and each such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor trustee relates; but, on request of the Company or any successor trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor trustee, to the extent contemplated by such supplemental indenture, the property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor trustee relates.

(c) Upon request of any such successor trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

(d) No successor trustee shall accept its appointment unless at the time of such acceptance such successor trustee shall be qualified and eligible under this Article.

(e) Upon acceptance of appointment by a successor trustee as provided in this Section, the Company shall transmit notice of the succession of such trustee hereunder by mail, first class postage prepaid, to the Securityholders, as their names and addresses appear upon the Security Register. If the Company fails to transmit such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be transmitted at the expense of the Company.

Section 7.12 Merger, Conversion, Consolidation or Succession to Business.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the corporate trust business of the Trustee, including the administration of the trust created by this Indenture, shall be the successor of the Trustee hereunder, provided that such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 7.13 Preferential Collection of Claims Against the Company.

The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent included therein.

Section 7.14 Notice of Default

If any Event of Default occurs and is continuing and if such Event of Default is known to a Responsible Officer of the Trustee, the Trustee shall mail to each Securityholder in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act notice of the Event of Default within the earlier of 90 days after it occurs and 30 days after it is known to a Responsible Officer of the Trustee or written notice of it is received by the Trustee, unless such Event of Default has been cured; provided, however , that, except in the case of a default in the payment of the principal of (or premium, if any) or interest on any Security, the Trustee shall be protected in withholding such notice if and so long as it in good faith determines that the withholding of such notice is in the interest of the Securityholders.

ARTICLE 8

CONCERNING THE SECURITYHOLDERS

Section 8.01 Evidence of Action by Securityholders.

Whenever in this Indenture it is provided that the holders of a majority or specified percentage in aggregate principal amount of the Securities of a particular series 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 majority or specified percentage of that series have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by such holders of Securities of that series in person or by agent or proxy appointed in writing.

If the Company shall solicit from the Securityholders of any series any request, demand, authorization, direction, notice, consent, waiver or other action, the Company may, at its option, as evidenced by an Officer’s Certificate, fix in advance a record date for such series for the determination of Securityholders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other action, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be given before or after the record date, but only the Securityholders of record at the close of business on the record date shall be deemed to be Securityholders for the purposes of determining whether Securityholders of the requisite proportion of Outstanding Securities of that series have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Securities of that series shall be computed as of the record date; provided, however, that no such authorization, agreement or consent by such Securityholders on the record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

Section 8.02 Proof of Execution by Securityholders.

Subject to the provisions of Section 7.01, proof of the execution of any instrument by a Securityholder (such proof will not require notarization) or his agent or proxy and proof of the holding by any Person of any of the Securities shall be sufficient if made in the following manner:

(a) The fact and date of the execution by any such Person of any instrument may be proved in any reasonable manner acceptable to the Trustee.

(b) The ownership of Securities shall be proved by the Security Register of such Securities or by a certificate of the Security Registrar thereof.

The Trustee may require such additional proof of any matter referred to in this Section as it shall deem necessary.

Section 8.03 Who May be Deemed Owners.

Prior to the due presentment for registration of transfer of any Security, the Company, the Trustee, any paying agent and any Security Registrar may deem and treat the Person in whose name such Security shall be registered upon the books of the Company as the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, and (subject to Section 2.03) interest on such Security and for all other purposes; and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any notice to the contrary.

Section 8.04 Certain Securities Owned by Company Disregarded.

In determining whether the holders of the requisite aggregate principal amount of Securities of a particular series have concurred in any direction, consent or waiver under this Indenture, the Securities of that series that are owned by the Company or any other obligor on the Securities of that series or by any Person directly or indirectly controlling or controlled by or under common control with the Company or any other obligor on the Securities of that series shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Securities of such series that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. The Securities so owned that have been pledged in good faith may be regarded as Outstanding for the purposes of this Section, if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.

Section 8.05 Actions Binding on Future Securityholders.

At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the holders of the majority or percentage in aggregate principal amount of the Securities of a particular series specified in this Indenture in connection with such action, any holder of a Security of that series that is shown by the evidence to be included in the Securities the holders of which have consented to such action may, by filing written notice with the Trustee, and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Security. Except as aforesaid any such action taken by the holder of any Security shall be conclusive and binding upon such holder and upon all future holders and owners of such Security, and of any Security issued in exchange therefor, on registration of transfer thereof or in place thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any action taken by the holders of the majority or percentage in aggregate principal amount of the Securities of a particular series specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the holders of all the Securities of that series.

ARTICLE 9

The Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into any such supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Any supplemental indenture authorized by the provisions of this Section may be executed by the Company and the Trustee without the consent of the holders of any of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 9.02.

With the consent (evidenced as provided in Section 8.01) of the holders of not less than a majority in aggregate principal amount of the Securities of each series affected by such supplemental indenture or indentures at the time Outstanding, the Company, when authorized by a Board Resolution, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as then in effect) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner not covered by Section 9.01 the rights of the holders of the Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the holders of each Security then Outstanding and affected thereby, (a) extend the fixed maturity of any Securities of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof or (b) reduce the aforesaid percentage of Securities, the holders of which are required to consent to any such supplemental indenture.

It shall not be necessary for the consent of the Securityholders of any series affected thereby under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof.

Section 9.03 Effect of Supplemental Indentures.

Upon the execution of any supplemental indenture pursuant to the provisions of this Article or of Section 10.01, this Indenture shall, with respect to such series, be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the holders of Securities of the series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 9.04 Securities Affected by Supplemental Indentures.

Securities of any series affected by a supplemental indenture, authenticated and delivered after the execution of such supplemental indenture pursuant to the provisions of this Article or of Section 10.01, may bear a notation in form approved by the Company, provided such form meets the requirements of any securities exchange upon which such series may be listed, as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of that series so modified as to conform, in the opinion of the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered in exchange for the Securities of that series then Outstanding.

The Company shall pay, or cause the Paying Agent to pay, interest (i) on any Physical Notes (A) to Holders holding Physical Notes having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Notes at their address as it appears in the Security Register and (B) to Holders holding Physical Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to each such Holder or, upon written application by such a Holder to the Security Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Security Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. The second paragraph of Section 2.03 of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 2.04(b), and any reference in the Base Indenture to such paragraph of Section 2.03 shall, with respect to the Notes, be deemed to refer instead to this Section 2.04(b).

(c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below:

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be sent electronically or mailed, first-class postage prepaid, to each Holder at its address as it appears in the Security Register, not less than 10 days prior to

such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so sent or mailed, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.04(c).

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

The third paragraph of Section 2.03 of the Base Indenture shall be superseded in its entirety by this Section 2.04(c), and any reference in the Base Indenture to such paragraph of Section 2.03 of the Base Indenture shall be deemed to refer instead to this Section 2.04(c).

Section 2.05 . Execution, Authentication and Delivery of Notes. Notwithstanding anything in the Base Indenture to the contrary, only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually by an authorized officer of the Trustee (or an Authenticating Agent appointed by the Trustee as provided by Section 2.10 of the Base Indenture), shall be entitled to the benefits of the Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an Authenticating Agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of the Indenture.

Section 2.06 . Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) Notwithstanding anything in the Base Indenture to the contrary, none of the Company, the Trustee or the Security Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15.

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

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the second paragraph of Section 2.06(c) all Notes shall be represented by one or more Global Notes registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary in accordance with the Indenture and the procedures of the Depositary therefor.

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for the Depositary. The Trustee shall have no responsibility for the actions of the Depositary.

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

None of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

(c) Section 2.11(c) of the Base Indenture shall be superseded by this Section 2.06(c), and any reference in the Base Indenture to Section 2.11(c) thereof shall be deemed to refer instead to this Section 2.06(c).

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

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.06(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, 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.

(d) Any Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted security” (as defined under Rule 144 under the Securities Act). The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.07.

Section 2.07 . Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, repurchase, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s Agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation pursuant to Section 2.08 of the Base Indenture and such Notes shall no longer be considered “Outstanding” upon their repurchase. All Notes delivered to the Trustee shall be canceled promptly by it, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of the Indenture.

Section 2.08 . CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 2.09 . Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.02, reopen the Indenture and issue additional Notes under the Indenture with the same terms as the Notes initially issued hereunder (other than differences in the issue price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 13.07 of the Base Indenture, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives, in each case without prior notice to the Holders. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.07.

ARTICLE 4
PARTICULAR COVENANTS OF THE COMPANY

Section 4.01 . Payment of Principal and Interest. This Section 4.01 shall supersede Section 4.01 of the Base Indenture and all references in the Base Indenture to Section 4.01 thereof shall be deemed, for the purposes of the Notes, to be references to this Section 4.01. The Company covenants and agrees that it will cause to be paid the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes.

Section 4.02 . Paying Agent and Conversion Agent. The office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“ Paying Agent ”) and Security Registrar for the Notes shall be located in the continental United States of America and shall initially be at the Corporate Trust Office of the Trustee. The Company will also maintain an office or agency (“ Conversion Agent ”) in the continental United States of America where the Notes may be surrendered for conversion and where notices and demands in respect of the Notes and the Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such offices or agencies. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee.

The Company may also from time to time designate as co-Security Registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the continental United States of America for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “ Paying Agent ” and “ Conversion Agent ” include any such additional or other offices or agencies, as applicable.

The Company hereby initially designates the Trustee as the Paying Agent, Security Registrar, Custodian, Conversion Agent and Bid Solicitation Agent and the Corporate Trust Office as the office or agency where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase or for conversion and where notices and demands in respect of the Notes and the Indenture may be served.

Section 4.03 . Provisions as to Paying Agent. (a) Section 4.03(a)(3) of the Base Indenture is hereby amended with respect to the Notes by replacing such Section 4.03(a)(3) in its entirety with the following: “that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust; and”.

Notwithstanding anything in the Base Indenture to the contrary, the Company shall, on or before each due date of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date.

(b) Notwithstanding anything in the Base Indenture to the contrary, if the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if

applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable.

(c) Notwithstanding anything in the Base Indenture to the contrary, any money and shares of Common Stock deposited with the Trustee, Conversion Agent or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price, if applicable), interest or consideration due upon conversion has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee, Conversion Agent or such Paying Agent with respect to such trust money and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease.

(b) Delivery of the reports and documents described in subsection (a) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate).

Section 4.06 . Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of the Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 4.07 . Compliance Certificate; Statements as to Defaults. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2014) an Officer’s Certificate signed by the principal executive, financial or accounting officer of the Company stating whether the signers thereof have knowledge of any failure by the Company to comply with all conditions and covenants then required to be performed under the Indenture and, if so, specifying each such failure and the nature thereof.

Section 13.12 of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 4.07, and any reference in the Base Indenture to such Section 13.12 shall, with respect to the Notes, be deemed to refer instead to this Section 4.07.

Section 4.08 . Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of the Indenture.

Section 4.09 . Additional Amounts.

In the event that any such withholding or deduction is so required, the Successor Company shall pay such additional amounts (the “ Additional Amounts ”) as may be necessary to ensure that the net amount received by the beneficial owner after such withholding or deduction (and after deducting or withholding any taxes on the Additional Amounts) shall equal the amounts that would have been received by such beneficial owner had no such withholding or deduction been required; provided that no Additional Amounts shall be payable:

(i) for or on account of:

(A) any tax, duty, assessment or other governmental charge that would not have been imposed but for:

(1) the existence of any present or former connection between the Holder or beneficial owner of such Note and the Relevant Taxing Jurisdiction, other than merely holding such Note or the receipt of payments thereunder, including, without limitation, such Holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Taxing Jurisdiction or treated as a resident thereof or being or having been physically present or engaged in a trade or business therein or having or having had a permanent establishment therein;

(2) the presentation of such Note (in cases in which presentation is required) more than 30 days after the later of the date on which the payment of the principal of (including the Fundamental Change Repurchase Price, if applicable) and interest on, such Note or the delivery of Common Stock and other Reference Property and/or payments of cash, in each case, upon conversion of such Note became due and payable pursuant to the terms thereof or was made or duly provided for; or

(3) the failure of the Holder or beneficial owner to comply with a timely request from the Successor Company to provide certification, information, documents or other evidence concerning such Holder’s or beneficial owner’s nationality, residence, identity or connection with the Relevant Taxing Jurisdiction, or to make any declaration or satisfy any other reporting requirement relating to such matters, if and to the extent that due and timely compliance with such

request is required by statute, regulation or administrative practice of the Relevant Taxing Jurisdiction in order to reduce or eliminate any withholding or deduction as to which Additional Amounts would have otherwise been payable to such Holder or beneficial owner;

(B) any estate, inheritance, gift, sale, transfer, excise, personal property or similar tax, assessment or other governmental charge;

(C) any tax, duty, assessment or other governmental charge that is payable otherwise than by withholding or deduction from payments under or with respect to the Notes;

(D) any tax, assessment, withholding or deduction required by sections 1471 through 1474 of the United States Internal Revenue Code of 1986, as amended (“ FATCA ”), any current or future Treasury Regulations or rulings promulgated thereunder, any law, regulation or other official guidance enacted in any jurisdiction implementing FATCA, any intergovernmental agreement between the United States and any other jurisdiction to implement FATCA or any law enacted by such other jurisdiction to give effect to such agreement, or any agreement with the U.S. Internal Revenue Service under FATCA; or

(E) any combination of taxes referred to in the preceding clauses (A), (B), (C) and (D), or

(ii) with respect to any payment of the principal of (including the Fundamental Change Repurchase Price, if applicable) and interest on, such Note or the delivery of Common Stock or other Reference Property and/or payments of cash, in each case, upon conversion of such Note to a Holder, if the Holder is a fiduciary, partnership or person other than the sole beneficial owner of that payment to the extent that such payment would be required to be included in the income under the laws of the Relevant Taxing Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a partner or member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner, member or beneficial owner been the Holder thereof.

(b) In the event that (i) the taxing authority of a Relevant Taxing Jurisdiction determines that amounts should have been withheld or deducted in respect of any payments or deliveries under or with respect to the Notes in excess of any amounts that were actually withheld or deducted by the Successor Company, and (ii) the Successor Company would have been required to pay Additional Amounts if such amounts had been withheld or deducted, then the Successor Company shall indemnify each beneficial owner of the Notes, on an after-tax basis, for any and all losses incurred as a result of its failure to make such withholdings and deductions and to pay Additional Amounts; provided that (i) only direct losses (and no consequential losses or damages) shall be recoverable pursuant to this Section 4.09(b), (ii) no indemnification shall be required pursuant to this Section 4.09(b) unless and after such beneficial owner has exhausted all reasonable remedies available to it to reduce or eliminate the amount of such losses, and (iii) as a condition of such indemnification such beneficial owner shall reasonably assist the Successor

Company in any attempt the Successor Company may make to seek to secure a reduction or refund of any such amounts, which reduction or refund shall be for the account of the Successor Company to the extent of any indemnification previously provided to such beneficial owner.

(c) If the Successor Company is required to make any deduction or withholding from any payments with respect to the Notes, the Successor Company will deliver to the Trustee official tax receipts evidencing the remittance to the relevant tax authorities of the amounts so withheld or deducted or other evidence reasonably satisfactory to the trustee.

(d) Any reference in this Supplemental Indenture or the Notes in any context to the delivery of Common stock or other Reference Property and/or payments of cash, in each case, upon conversion of any Note or the payment of principal of (including the Fundamental Change Repurchase Price, if applicable) and interest on, any Note or any other amount payable with respect to such Note, shall be deemed to include payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to this Section 4.09.

Section 6.03. 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 6.02(i) or Section 6.02(j) with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding determined in accordance with Section 8.04 of the Base Indenture, by notice in writing to the Company (and to the Trustee if given by Holders), may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable.

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 7.06 of the Base Indenture, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.10, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then Outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes.

Section 6.04. Additional Interest . Notwithstanding anything in the Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to (i) the failure by the Company to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act or (ii) the Company’s failure to comply with its obligations as set forth in Section 4.05(a) (the obligations described in clauses (i) and (ii), the “ Reporting Obligations ”) shall (x) for the first 180 days after the occurrence of such an Event of Default (beginning on, and including, the date on which such an Event of Default first occurs), consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes Outstanding for each day during such 180-day period on which such Event of Default is continuing and (y) for the period from, and including, the 181st day after the occurrence of such an Event of Default to, and including, the 270th day after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of the Notes Outstanding for each day during such 90-day period on which such Event of Default is continuing. In no event shall the Additional Interest described in this Section 6.04 accrue at a rate in excess of 0.25% per annum during the initial 180-day period or 0.50% per annum during the subsequent 90-day period, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

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 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 day), the Notes shall be immediately subject to acceleration as provided in Section 6.03. In the event the Company does not elect to pay Additional Interest following an Event of Default relating to the Reporting Obligations in accordance with this Section 6.04 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.03.

In order to elect to pay Additional Interest as the sole remedy during the first 270 days after the occurrence of any Event of Default relating to the failure by the Company to comply with the Reporting Obligations, in accordance with this Section 6.04, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 270-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.03. The Trustee shall not at any time be under any duty or responsibility to any Holder of Notes to determine the Additional Interest, or with respect to the nature, extent, or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

Section 6.05 . Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 6.02 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 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 7.06 of the Base Indenture. If the Company shall fail to 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.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.05, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses and disbursements of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings 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 7.06 of the Base Indenture; 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 and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06 of the Base Indenture, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses 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 and disbursements 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 6.10 or any rescission and annulment pursuant to Section 6.03 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.

Section 6.06 . Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First , to the payment of all amounts due the Trustee and its agents under the Base Indenture;

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

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

principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and

Fourth , to the payment of the remainder, if any, to the Company.

Section 6.07 . Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided;

(b) Holders of at least 25% in aggregate principal amount of the Notes then Outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder;

(c) such Holders shall have offered to the Trustee such security or indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby;

(d) the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and

(e) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then Outstanding within such 60-day period pursuant to Section 6.10,

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and 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 6.07, 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, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase 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, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such

respective dates against the Company shall not be impaired or affected without the consent of such Holder.

Section 6.08 . 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 6.09 . Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07 of the Base Indenture, all powers and remedies given by this Article 6 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 6.07, every power and remedy given by this Article 6 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 6.10 . Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority of the aggregate principal amount of the Notes at the time Outstanding determined in accordance with Section 8.04 of the Base Indenture 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 the 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 determined in accordance with Section 8.04 of the Base Indenture may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.02, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an Outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.10, 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.

Section 6.11 . Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, send to all Holders as the names and addresses of such Holders appear upon the Security Register, notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes 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 the withholding of such notice is in the interests of the Holders. This Section 6.11 shall supersede Section 7.14 of the Base Indenture, and any reference in the Base Indenture to such Section 7.14 thereof shall be deemed to refer instead to this Section 6.11. The proviso set forth in Section 315(b) of the Trust Indenture Act shall not apply with respect to the Notes.

Section 6.12 . 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, 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 6.12 (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 determined in accordance with Section 8.04 of the Base Indenture, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price, if applicable) 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 14.

(l) to conform the provisions of the Indenture or the Notes to the “Description of notes” section of the Prospectus Supplement as evidenced in an Officer’s Certificate.

Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise.

Any supplemental indenture authorized by the provisions of this Section 10.02 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time Outstanding, notwithstanding any of the provisions of Section 10.03.

Section 10.03 . Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8 of the Base Indenture) of the Holders of at least a majority of the aggregate principal amount of the Notes then Outstanding (determined in accordance with Article 8 of the Base Indenture and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided , however , that, without the consent of each Holder of an Outstanding Note affected, no such supplemental indenture shall:

(a) reduce the amount of Notes whose Holders must consent to an amendment;

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

(d) make any change that adversely affects the conversion rights of any Notes other than as required by the Indenture;

(e) reduce the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse to the Holders the Company’s obligation to make such payments, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise;

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

(g) change the ranking of the Notes;

(h) impair the right of any Holder to receive payment of principal and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes;

(i) change the provisions set forth in Section 4.09 in a manner adverse to the Holders; or

(j) make any change in this Article 10 that requires each Holder’s consent or in the waiver provisions in Section 6.03 or Section 6.10.

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.06, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

Holders do not need under this Section 10.03 to approve the particular form of any proposed supplemental indenture. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture.

Section 10.04 . Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 10, the Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under the Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of the Indenture for any and all purposes.

Section 10.05 . Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided

for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of the Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an Authenticating Agent duly appointed by the Trustee pursuant to Section 2.10 of the Base Indenture) and delivered in exchange for the Notes then Outstanding, upon surrender of such Notes then Outstanding.

Section 10.06 . Evidence of Compliance of Supplemental Indenture to Be Furnished to Trustee. In addition to the documents required by Section 13.07 of the Base Indenture, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 10, is permitted or authorized by the Indenture and is the legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms.

ARTICLE 11
CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

Section 11.01 . Applicability of Article 10 and Section 4.05 of the Base Indenture.

(a) Article 10 of the Base Indenture shall not apply to the Notes. Instead the provisions set forth in this Article 11 shall, with respect to the Notes, supersede in their entirety Article 10 of the Base Indenture, and all references in the Base Indenture to Article 10 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 11 or the applicable provisions set forth in this Article 11, respectively.

(b) Section 4.05 of the Base Indenture and any reference in the Base Indenture to any such Section or the provisions contained therein shall be deemed deleted with respect to the Notes.

Section 11.02 . Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 11.03, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless:

(a) the resulting, surviving or transferee Person (the “ Successor Company ”), if not the Company, shall be (1) a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia or (2) a corporation or entity treated as a corporation for U.S. federal income tax purposes organized and existing under the laws of the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company under the Notes and the Indenture (including, for the avoidance of doubt, the obligation to pay Additional Amounts, as set forth in Section 4.09);

(b) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, transfer or lease and such supplemental indenture, if any, is authorized or permitted by, and complies with, the Indenture; and

(c) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under the Indenture.

For purposes of this Section 11.02, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person.

Section 11.03 . Successor Company to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon a Company Order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in the Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under the Indenture as the Notes theretofore or thereafter issued in accordance with the terms of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article 11 the Person named as the “Company” in the first paragraph of this Supplemental Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under the Indenture and the Notes.

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

Section 11.04 . Opinion of Counsel to Be Given to Trustee. No such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 11.

ARTICLE 12
NO RECOURSE

Section 12.01 . No Recourse.

No recourse under or upon any obligation, covenant or agreement of this Supplemental Indenture, or of the Notes, or for any claim based thereon or otherwise in respect thereof, shall be had against any incorporator, stockholder, officer or director, past, present or future as such, of the Company, of any predecessor or Successor Company or of any issuer of any securities underlying the Notes, either directly or through the Company, any such predecessor or Successor Company or any such issuer, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that this Supplemental Indenture and the obligations issued hereunder are solely corporate obligations, and that no such personal liability whatever shall attach to, or is or shall be incurred by, the incorporators, stockholders, officers or directors as such, of the Company, of any such predecessor or Successor Company or any such issuer, or any of them, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in this Supplemental Indenture or in the Notes or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in equity or by constitution or statute, of, and any and all such rights and claims against, every such incorporator, stockholder, officer or director as such, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in this Supplemental Indenture or in the Notes or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Supplemental Indenture and the issuance of the Notes.

ARTICLE 13
[INTENTIONALLY OMITTED]

ARTICLE 14
CONVERSION OF NOTES

Section 14.01 . Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 14, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described in

Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding May 15, 2018 under the circumstances and during the periods set forth in Section 14.01(b), and (ii) regardless of the conditions described in Section 14.01(b), on or after May 15, 2018 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 36.9079 shares of Common Stock (subject to adjustment as provided in this Article 14, the “ Conversion Rate ”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.02, the “ Conversion Obligation ”).

(b) (i) Prior to the close of business on the Business Day immediately preceding May 15, 2018, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day period (the “ Measurement Period ”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Supplemental Indenture. 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 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 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 which time the Company shall instruct the Bid Solicitation Agent to 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 Company does not instruct the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) within one Business Day. 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 so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee).

(ii) If, prior to the close of business on the Business Day immediately preceding May 15, 2018, the Company elects to:

(A) issue to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the 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 date of announcement of such issuance; 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 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 date of announcement for such distribution,

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 90 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, a Holder may surrender all or any portion of its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, in each case.

(iii) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding May 15, 2018, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets (other than any merger or binding share exchange, in each case, solely for the purpose of changing the Company’s jurisdiction of organization that (x) does not constitute a Fundamental Change or a Make-Whole Fundamental Change and (y) results in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of common stock of the surviving entity), all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the date that is 90 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 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 90 Scheduled Trading Days prior to the anticipated effective date of such transaction or (ii) if the Company does not have knowledge of the anticipated effective date of such transaction at least 90 Scheduled Trading Days prior to the anticipated effective date of such transaction, within five Business Days of the date

upon which the Company has knowledge of the anticipated effective date of such transaction, but in no event later than the actual effective date of such transaction.

(iv) Prior to the close of business on the Business Day immediately preceding May 15, 2018, a Holder may surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on March 31, 2014 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. The Company shall determine at the beginning of each calendar quarter commencing after March 31, 2014 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Conversion Agent (if other than the Trustee) and the Trustee as to whether or not the Notes become convertible in accordance with this clause (iv).

Section 14.02 . Conversion Procedure; Settlement Upon Conversion.

(a) Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“ Cash Settlement ”), shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“ Physical Settlement ”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“ Combination Settlement ”), at its election, as set forth in this Section 14.02.

(i) All conversions for which the relevant Conversion Date occurs on or after May 15, 2018 shall be settled using the same Settlement Method.

(ii) Except for any conversions for which the relevant Conversion Date occurs on or after May 15, 2018, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates.

(iii) If, in respect of any Conversion Date (or the period described in the fourth immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “ Settlement Notice ”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Conversion Agent, shall deliver such Settlement Notice to the Trustee, the Conversion Agent (if other than the Trustee) and converting Holders no later than the close of business on the second Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs on or after May 15, 2018, no later than May 15, 2018). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence,

the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000.

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

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

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 80 consecutive Trading Days during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 80 consecutive Trading Days during the related Observation Period.

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

(b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “ Notice of Conversion ”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03.

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

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “ Conversion Date ”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 14.03(b) and Section 14.07(a), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following the last Trading Day of the Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

(d) In case any Physical Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or 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 submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests any such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax.

(f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 14.

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

(h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. However, 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 such interest payable on the Notes so converted; 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 Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date, in respect of Notes converted after the Close of Business on such Regular Record Date and on or prior to the Open of Business on such Interest Payment Date; or (3) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date regardless of whether their Notes have been converted following such Regular Record Date.

(i) The Person in whose name the shares of Common Stock shall be issuable upon conversion shall become the holder of record of such shares as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company

elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion.

(j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected (or is deemed to have elected) Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash.

Section 14.03 . Increased Conversion Rate Applicable to Certain Notes Surrendered 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 elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “ Additional Shares ”), as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition 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 pursuant to Section 14.01(b)(iii), the Company shall , at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.02; provided , however , that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the 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 pursuant to this Section 14.03), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Trustee, the Conversion Agent (if other than the Trustee) and the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective Date.

(c) The amount, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “ Effective Date ”) and the price (the “ Stock Price ”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the 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. The Company shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date (as such term is used in Section 14.04) or expiration date of the event occurs during such five consecutive Trading Day period.

(d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The amounts by which the Conversion Rate shall be increased as set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 14.04.

(e) The following table sets forth the amount, if any, by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date set forth below:

	Stock Price
Effective Date	$20.07	$25.00	$27.09	$30.00	$35.00	$40.00	$45.00	$50.00	$60.00	$75.00	$100.00
February 14, 2014	12.9177	8.4712	7.2196	5.8663	4.2463	3.1768	2.4351	1.9000	1.1933	0.5961	0.0962

February 15, 2017	12.9177	6.6316	5.2754	3.9067	2.4491	1.6288	1.1416	0.8364	0.4952	0.2553	0.0722
February 15, 2018	12.9177	5.5812	4.0956	2.7047	1.4191	0.8288	0.5387	0.3826	0.2295	0.1279	0.0451
February 15, 2019	12.9177	3.0920	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000

The exact Stock Prices and Effective Dates 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 above or the Effective Date is between two Effective Dates in the table, the amount by which the Conversion Rate shall be increased shall be determined by a straight-line interpolation between the amount of the Conversion Rate increase set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

(ii) if the Stock Price is greater than $100.00 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 subsection (d) above), the Conversion Rate shall not be increased; and

(iii) if the Stock Price is less than $20.07 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 subsection (d) above), the Conversion Rate shall not be increased.

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 49.8256 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04.

(f) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04 in respect of a Make-Whole Fundamental Change.

Section 14.04 . 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 (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(a) If the Company 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:

where,

CR 0 = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as applicable;

CR' = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;

OS 0 = the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and

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

Any adjustment made under this Section 14.04(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 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the 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 date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula:

where,

CR 0 = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;

CR' = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

OS 0 = the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;

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

Y = the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of the Common Stock are not delivered 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 issuance of such rights, options or warrants been made on the basis of delivery of only the

number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued or if no such right, option or warrant is exercised prior to its expiration, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For purposes of this Section 14.04(b) and for the purpose of Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the 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 date of announcement for such issuance, 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, distributions or issuances as to which an adjustment was effected pursuant to Section 14.04(a) or Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 14.04(d), (iii) dividends or distributions of Reference Property in exchange for Common Stock in connection with any Share Exchange Event, and (iv) Spin-Offs as to which the provisions set forth below in this Section 14.04(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, the “ Distributed Property ”), then the Conversion Rate shall be increased based on the following formula:

where,

CR 0 = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR' = the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

SP 0 = the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

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

Any increase made under the portion of this Section 14.04(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 receive the Distributed Property, 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. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 14.04(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 the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

With respect to an adjustment pursuant to this Section 14.04(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,

CR 0 = the Conversion Rate in effect immediately prior to the end of the Valuation Period;

CR' = the Conversion Rate in effect immediately after the end of the Valuation Period;

FMV 0 = the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “ Valuation Period ”); and

MP 0 = the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

The increase to the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the Valuation Period; provided that in respect of any conversion of Notes during the Valuation Period, references in the portion of this Section 14.04(c) related to Spin-Offs 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 the Conversion Date in determining the Conversion Rate. If the Ex-Dividend Date of the Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references in the preceding paragraph 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.

For purposes of this Section 14.04(c) (and subject in all respects to Section 14.11), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“ Trigger Event ”): (i) are deemed to be transferred with such shares of the 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 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(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 14.04(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 14.04(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 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 14.04(a), Section 14.04(b) and this Section 14.04(c), if any dividend or distribution to which this Section 14.04(c) is applicable also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the “ Clause A Distribution ”); or

(B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable (the “ Clause B Distribution ”),

then, in either case, (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 14.04(c) is applicable (the “ Clause C Distribution ”) and any Conversion Rate adjustment required by this Section 14.04(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 14.04(a) and Section 14.04(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 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b).

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

where,

CR 0 = the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

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

SP 0 = the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C = the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

Any increase to the Conversion Rate pursuant to this Section 14.04(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 the Common Stock, 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 make a payment pursuant to a tender or exchange offer for the Common Stock that is subject to the then-applicable tender offer rules under the Exchange Act, other than an odd lot tender offer, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, 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,

CR 0 = the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;

CR' = the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;

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

OS 0 = the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase or exchange of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

OS' = the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase or exchange of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and

SP' = the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

The increase to the Conversion Rate under this Section 14.04(e) shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any

conversion of Notes within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires, references in this Section 14.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange offer expires and the Conversion Date in determining the Conversion Rate. In addition, if the Trading Day next succeeding the date such tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references in the preceding paragraph 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 date such tender or exchange offer expires to, and including, the last Trading Day of such Observation Period.

(f) Notwithstanding this Section 14.04 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 14.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

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

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, 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 Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Security Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i) Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be adjusted:

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

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

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

(iv) upon the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the kind described in Section 14.04(e);

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

(vi) for accrued and unpaid interest, if any.

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. The Company shall not adjust the Conversion Rate pursuant to this Section 14.04 unless the adjustment would result in a change of at least 1% in the then-effective Conversion Rate. However, the Company shall carry forward any adjustment that it would otherwise have to make and take that adjustment into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with respect to the Notes (i) in connection with any subsequent adjustment to the Conversion Rate of at least 1% and (ii)(a) on each Trading Day of any Observation Period related to the conversion of Notes (in the case of Cash Settlement or Combination Settlement) or (b) on the Conversion Date for any Notes (in the case of Physical Settlement).

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s 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 Security Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 14.05 . 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 the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Company shall, in good faith, make appropriate adjustments (to the extent no corresponding adjustment is otherwise made pursuant to Section 14.04) 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 (as such term is used in Section 14.04) or expiration date of the event occurs at any time during the period when such Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

Section 14.06 . Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming (x) that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement is applicable and (y) the delivery of the maximum number of shares of Common Stock, including the maximum Conversion Rate increase pursuant to Section 14.03).

Section 14.07 . 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 share split, share combination or change in par value),

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

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

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “ Share Exchange Event ”), then, at and after the effective time of such Share Exchange Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a

holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Share Exchange Event would have owned or been entitled to receive (the “ Reference Property ,” with each “ unit of Reference Property ” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Share Exchange Event and, prior to or at the effective time of such Share Exchange Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.02(f) providing for such change in the right to convert each $1,000 principal amount of Notes; provided , however , that at and after the effective time of the 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 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Share Exchange Event and (III) the Daily VWAP and the Last Reported Sale Price, as applicable, shall be calculated based on the value of a unit of Reference Property.

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 Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders 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. If the holders of the Common Stock receive only cash in such Share Exchange Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Share Exchange Event (A) 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 pursuant to Section 14.03), multiplied by the price paid per share of Common Stock in such Share Exchange Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 14. If, in the case of any Share Exchange Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing company, as the case may be, in such Share Exchange Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably

consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 15.

(b) When the Company executes a supplemental indenture pursuant to subsection (a) of this Section 14.07, the Company shall promptly file with the Trustee an Officer’s 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, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the Security Register provided for in the Indenture, within 20 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 14.07. None of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 14.01 and Section 14.02 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 14.08 . Certain Covenants. (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens, charges and preemptive rights 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 governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission, 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 will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes.

Section 14.09 . Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or

cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, 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. Neither the Trustee nor any other Conversion Agent shall have any duty or responsibility whatsoever to determine compliance with the conversion procedures, or to make or confirm any calculations with respect to the settlement provisions, of Section 14.02. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 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 14.07 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 Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 14.01(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 the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). The rights, benefits and privileges of the Trustee set forth in the Base Indenture shall be applicable to the Conversion Agent, and the provisions set forth in Section 7.01 of the Base Indenture relating to the Trustee shall apply to the Conversion Agent.

Section 14.10 . Intentionally Omitted.

Section 14.11 . Stockholder Rights Plans. If the Company has a stockholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case, as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 14.12 . Intentionally Omitted.

Section 14.13 . Exchange in Lieu of Conversion. Notwithstanding anything herein to the contrary, when a Holder surrenders Notes for conversion, the Company may, at its election (an “ Exchange Election ”), direct the Conversion Agent to surrender, on or prior to the second Trading Day following the Conversion Date, such Notes to a financial institution designated by the Company for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution must agree to timely deliver, in exchange for such Notes, the shares of Common Stock, cash or combination thereof due upon conversion at the time and in the manner provided in this Article 14. If the Company makes an Exchange Election, the Company shall, by the close of business on the second Trading Day following the relevant Conversion Date, notify the Holder surrendering Notes for conversion that the Company has made the Exchange Election and the Company shall notify the designated financial institution of the Settlement Method the Company has elected with respect to such conversion and the relevant deadline for payment and/or delivery of the shares of Common Stock, cash or a combination thereof due upon conversion.

Any Notes exchanged by the designated financial institution shall remain Outstanding. If the designated financial institution agrees to accept any Notes for exchange but does not timely pay and/or deliver the shares of Common Stock, cash or a combination thereof due upon conversion, or if such designated financial institution does not accept the Notes for exchange, the Company shall pay and/or deliver the shares of Common Stock, cash or a combination thereof due upon conversion to the converting Holder at the time and in the manner provided in this Article 14 as if the Company had not made an Exchange Election.

The Company’s designation of a financial institution to which Notes may be submitted for exchange does not require the financial institution to accept any Notes (unless the financial institution has separately made an agreement with the Company). The Company may, but is not obligated to, enter into a separate agreement with any designated financial institution that would compensate it for any such transactions.

ARTICLE 15
REPURCHASE OF NOTES AT OPTION OF HOLDERS

Section 15.01 . Intentionally Omitted.

Section 15.02 . Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior to the Maturity Date, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the “ Fundamental Change Repurchase Date ”) specified by the Company that is not less than 20 Business Days or more than 35 Business Days following the date of the Fundamental Change Company Notice, subject to postponement to comply with applicable law, at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “ Fundamental Change Repurchase Price ”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but

on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15.

(b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon:

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

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

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

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

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

(iii) that the Notes are to be repurchased 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 Repurchase Notice must comply with appropriate Depositary procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03.

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

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

(i) the events causing the Fundamental Change;

(ii) the effective date of the Fundamental Change;

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 15;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

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

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

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02.

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

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during

the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

(e) Notwithstanding the foregoing, the Company shall not be required to purchase, or to make an offer to purchase, any 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 in this Article 15 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 in this Article 15.

(f) To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article 15, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under such provisions of this Article 15 by virtue of such conflict.

Section 15.03 . Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 15.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

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

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

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

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

Section 15.04 . Deposit of Fundamental Change Repurchase 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 4.03 of the Base Indenture) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the close of business

on the Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date ( provided the Holder has satisfied the conditions in Section 15.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 15.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Security 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 Repurchase Price.

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been properly surrendered for repurchase and have not been validly withdrawn, (i) such Notes shall cease to be Outstanding, (ii) 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 (iii) all other rights of the Holders of such Notes shall terminate (other than the right to receive the Fundamental Change Repurchase Price).

(c) Upon surrender of a Physical Note that is to be repurchased in part pursuant to Section 15.02, 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 unrepurchased portion of the Note surrendered.

Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes . In connection with any repurchase offer, the Company shall, if required:

(a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act;

(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 repurchase the Notes;

in each case, so as to permit the rights and obligations under this Article 15 to be exercised in the time and in the manner specified in this Article 15.

2.50% Convertible Senior Note due 2019

This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.50% Convertible Senior Notes due 2019 (the “ Notes ”), limited to the aggregate principal amount of $200,000,000 all issued or to be issued under and pursuant to an Indenture dated as of February 14, 2014 (the “ Base Indenture ”), as amended and supplemented by the First Supplemental Indenture dated as of February 14, 2014 (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 Wilmington Trust, 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. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture.

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

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date 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 not less than a majority in aggregate principal amount of the Notes at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

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 Repurchase Price, if 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 and in the lawful money 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 referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

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

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

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, 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, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

Relevant Settlement Method:		In respect of any Option:

		(i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(a)(iv)(A) of the Supplemental Indenture (together with cash in lieu of fractional Shares) (such settlement method, “ Settlement in Shares ”), (B) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount less than USD 1,000 (such settlement method, “ Low Cash Combination Settlement ”) or (C) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement;

		(ii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount greater than USD 1,000, then the

		(iii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note entirely in cash pursuant to Section 14.02(a)(iv)(B) of the Supplemental Indenture (such settlement method, “ Settlement in Cash ”), then the Relevant Settlement Method for such Option shall be Cash Settlement.

Net Share Settlement:		If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “ Net Share Settlement Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that, for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date, in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the Settlement Date for such Option.

Combination Settlement:		If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:

		(i) cash (the “ Combination Settlement Cash Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “ Daily Combination Settlement Cash Amount ”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

		(ii) Shares (the “ Combination Settlement Share Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day

		(the “ Daily Combination Settlement Share Amount ”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

		provided that, for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date, in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the Combination Settlement Share Amount for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.

For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be

		made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Supplemental Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section 14.04(c) of the Supplemental Indenture or the fourth sentence of Section 14.04(d) of the Supplemental Indenture).

Dilution Adjustment Provisions:		Sections 14.04(a), 14.04(b), 14.04(c), 14.04(d) and 14.04(e) and Section 14.05 of the Supplemental Indenture.

		If, in respect of any Merger Event to which the immediately preceding paragraph applies, the adjustments to be made in accordance with such paragraph would result in Counterparty being different from the issuer of the Shares, then with respect to such Merger Event, as a condition precedent to the adjustments contemplated in the immediately preceding paragraph, Dealer, the Issuer of the Affected Shares and the entity that will be the Issuer of the New Shares shall, prior to consummation of such Merger Event, have entered into such documentation containing agreements relating to “tacking” and “holding period” related considerations under U.S. securities law and credit exposure assumed by Dealer as the result Merger Event, as reasonably requested by Dealer that Dealer has determined, in its good faith, reasonable judgment, to be reasonably necessary or appropriate to allow Dealer to continue as a party to the Transaction, as adjusted under the immediately preceding paragraph, and to preserve its hedging or hedge unwind activities in connection with the Transaction in a manner compliant with applicable legal, and regulatory requirements, and if such conditions are not met or if the Calculation Agent determines that no adjustment under the immediately preceding paragraph will produce a commercially reasonable result, then the consequences set forth in Section 12.2(e)(ii) of the Equity Definitions shall apply to such Merger Event (as if Merger Event were as defined in Section 12.1(b) of the Equity Definitions).

(ii) Dealer may transfer or assign all or any part of its rights or obligations under the Transaction (A) without Counterparty’s consent, to any third party (including, without limitation, any affiliate of Dealer) organized in the United States that has a rating at the time of such transfer or assignment for its long term, unsecured and unsubordinated indebtedness from either Standard and Poor’s Rating Group, Inc. or its successor (“ S&P ”) or Moody’s Investor Service, Inc. (“ Moody’s ”) (or, if both S&P and Moody’s ceases to rate such debt, by a substitute rating agency mutually agreed by Counterparty and Dealer) that is equal to or better than Dealer’s credit rating from such agency on the date hereof, or (B) with Counterparty’s consent, to any other third party (including, without limitation, any affiliate of Dealer) organized in the United States with a rating for its long term, unsecured and unsubordinated indebtedness from either S&P or Moody’s (or, if both S&P and Moody’s ceases to rate such debt, by a substitute rating agency mutually agreed by Counterparty and Dealer) that is equal to or better than Dealer’s credit rating from such agency at the time of the transfer; provided , in each case, that if such transfer or assignment would result in any tax withholding obligation of the transferee in respect of any tax and such withholding tax, without application of this sentence, would not be an Indemnifiable Tax, such tax shall be treated as an Indemnifiable Tax if such withholding tax obligation would not have applied to Dealer or such withholding tax would have been an Indemnifiable Tax of Dealer. Without limiting the foregoing, no transfer or assignment by Dealer shall be permitted hereunder that would result in the occurrence of an Event of Default, Potential Event of Default or Termination Event. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Option Equity Percentage exceeds 17.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “ Excess Ownership Position ”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party in accordance with the two, immediately preceding sentences on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “ Terminated Portion ”), such that following such partial termination no Excess Ownership Position exists. Dealer shall notify Counterparty of an Excess Ownership Position with respect to which it intends to seek a transfer or assignment as soon as reasonably practicable after becoming aware of such Excess Ownership Position. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “ Section 16 Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “ Option Equity Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts

of Counterparty that are, in each case, applicable to ownership of Shares (“ Applicable Restrictions ”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “ Applicable Share Limit ” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations (other than any Form 13F, Schedule 13D or Schedule 13G filing under the Exchange Act) or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or would result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.

(iii) Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

(f) Staggered Settlement . If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s commercially reasonable hedging activities hereunder, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “ Nominal Settlement Date ”), elect to deliver the Shares on two or more dates (each, a “ Staggered Settlement Date ”) as follows:

(i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th) Exchange Business Day following such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date;

(ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date;

(iii) if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case may be, will apply on each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause (i) above; and

(iv) when specifying Staggered Settlement Dates pursuant to this Section 9(f), Dealer shall specify the fewest number of Staggered Settlement Dates as is practicable under the circumstances.

(g) Role of Agent . Each party agrees and acknowledges that (i) J.P. Morgan Securities LLC, an affiliate of JPMorgan (“ JPMS ”), has acted solely as agent and not as principal with respect to the Transaction and (ii) JPMS has no obligation or liability, by way of guaranty, endorsement or otherwise, in any manner in respect of the Transaction (including, if applicable, in respect of the settlement thereof). Each party agrees it will look solely to the other party (or any guarantor in respect thereof) for performance of such other party’s obligations under the Transaction .

(h) Additional Termination Events .

(i) Notwithstanding anything to the contrary in this Confirmation if an event of default with respect to Counterparty occurs that results in an acceleration of the Convertible Notes under the terms of the Convertible Notes as set forth in Section 6.02 of the Supplemental Indenture, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.

(ii) Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty, within the applicable time period set forth under “Notice of Exercise” above, of any Notice of Exercise in respect of Options that relate to Convertible Notes as to which additional Shares would be added to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture in connection with a “Make-Whole Fundamental Change” (as defined in the Supplemental Indenture) shall constitute an Additional Termination Event as provided in this Section 9(h)(ii). Upon receipt of any such Notice of Exercise, Dealer shall designate an Exchange Business Day following such Additional Termination Event (which Exchange Business Day shall in no event be earlier than the related settlement date for such Convertible Notes) as an Early Termination Date (and Dealer shall use its reasonable efforts to designate such Early Termination Date so that the related payment hereunder in respect of the Make-Whole Conversion Options will occur on (or as promptly as reasonably practicable after) the related settlement for the conversion of the relevant Convertible Notes) with respect to the portion of this Transaction corresponding to a number of Options (the “ Make-Whole Conversion Options ”) equal to the lesser of (A) the number of such Options specified in such Notice of Exercise and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Make-Whole Conversion Options. Any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the number of Make-Whole Conversion Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were the sole Affected Transaction (and, for the avoidance of doubt, in determining the amount payable pursuant to Section 6 of the Agreement, the Calculation Agent shall not take into account any adjustments to the Option Entitlement that result from corresponding adjustments to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture); provided that the amount of cash deliverable in respect of such early termination by Dealer to Counterparty shall not be greater than the product of (x) the Applicable Percentage and (y) the excess of (I) (1) the number of Make-Whole Conversion Options, multiplied by (2) the Conversion Rate (after taking into account any applicable adjustments to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture), multiplied by (3) the per Share opening price as displayed under the heading “Op” on Bloomberg page AMAG <equity> (or any successor thereto) on the date on which Shares are delivered upon conversion to Holders of the Convertible Notes corresponding to such Make-Whole Conversion Options over (II) the aggregate principal amount of such Convertible Notes, as determined by the Calculation Agent in a commercially reasonable manner.

(i) Amendments to Equity Definitions .

following words therefor “or (C) the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master Agreement with respect to that Issuer.”

(ii) Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice to Counterparty” in the first sentence of such section.

(j) Setoff . Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable law or otherwise.

(k) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events . If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares consists solely of cash, (ii) a Merger Event that is within Counterparty’s control, or (iii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “ Payment Obligation ”), then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the Merger Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not apply, (b) Counterparty remakes the representation set forth in Section 8(f) as of the date of such election and (c) Dealer agrees, in its sole discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.

Share Termination Alternative:		If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable (the “ Share Termination Payment Date ”), in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.

Share Termination Delivery Property:		A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.

Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by

		the Calculation Agent in its good faith discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.

Share Termination Delivery Unit:		One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “ Exchange Property ”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.

Failure to Deliver:		Applicable

Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

(l) Waiver of Jury Trial . Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the Transaction. Each party (i) certifies that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

(n) Tax Disclosure . Effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to either party by the other relating to such tax treatment and tax structure.

(o) Right to Extend . Dealer may postpone or add, in whole or in part, any Valid Day or Valid Days during the Settlement Averaging Period or any other date of valuation, payment or delivery by Dealer, with respect to some or all of the Options hereunder, if Dealer reasonably determines (i) in its discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or (ii) based on the advice of counsel, to enable Dealer to effect purchases of Shares in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer.

(r) Notice of Certain Other Events . Counterparty covenants and agrees that:

(i) promptly following the public announcement of the results of any election by the holders of Shares with respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written notice of the types and amounts of consideration that holders of Shares have elected to receive upon consummation of such Merger Event (the date of such notification, the “ Consideration Notification Date ”); provided that in no event shall the Consideration Notification Date be later than the date on which such Merger Event is consummated; and

(ii) promptly following any adjustment to the Convertible Notes in connection with any Potential Adjustment Event or Merger Event, Counterparty shall give Dealer written notice of the details of such adjustment.

(s) Wall Street Transparency and Accountability Act . In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“ WSTAA ”), the parties hereby agree that neither the enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as defined in the Agreement)).

(t) Agreements and Acknowledgements Regarding Hedging . Counterparty understands, acknowledges and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be active in the market for Shares other than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in securities of Issuer shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Relevant Prices; and (D) any market activities of Dealer and its affiliates with respect to Shares may affect the market price and volatility of Shares, as well as the Relevant Prices, each in a manner that may be adverse to Counterparty.

(u) Early Unwind . In the event the sale of the “Firm Securities” (as defined in the Underwriting Agreement) is not consummated with the Underwriters for any reason, or Counterparty fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment Date or such later date, the “ Early Unwind Date ”), the Transaction shall automatically terminate (the “ Early Unwind ”) on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Counterparty under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date. Each of Dealer and Counterparty represents and acknowledges to the other that upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

(v) Payment by Counterparty . In the event that, following payment of the Premium, (i) an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero.

Counterparty following such Inversion Transaction is organized under the laws of a jurisdiction other than the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, then such Inversion Transaction shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. If, at any time following the occurrence of any Inversion Transaction, Dealer reasonably determines in its good faith judgment that (x) such Inversion Transaction has had a material adverse effect on Dealer’s rights and obligations under the Transaction or (y) Dealer would incur an increased (as compared with circumstances existing on the Trade Date) amount of tax, duty, expense or fee (other than brokerage commissions and excluding (I) any de minimis increased amount of tax, duty, expense or fee and (II) any such increased amount that is incurred solely due to the deterioration of the creditworthiness of Dealer), to (1) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the economic risk of entering into and performing its obligations with respect to the Transaction, or (2) realize, recover or remit the proceeds of any such transaction(s) or asset(s) (each of the events described in clause (x) and clause (y) above, an “ Inversion Event ”), then, in either case, Dealer shall give prompt notice to Counterparty of such Inversion Event. Concurrently with delivering such notice, Dealer shall give notice to Counterparty of a commercially reasonable Price Adjustment that Dealer determines, in its good faith, commercially reasonable judgment, appropriate to account for the economic effect on the Transaction of such Inversion Event and provide Counterparty with supporting documentation for such Price Adjustment (unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, in which case Dealer shall so notify Counterparty). Unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, within two Scheduled Trading Days of receipt of such notice, Counterparty shall notify Dealer that it elects to (A) agree to amend the Transaction to take into account such Price Adjustment or (B) pay Dealer an amount determined by Dealer (and in respect of which Dealer has provided to Counterparty supporting documentation) that corresponds to such Price Adjustment (and, in each case, Counterparty shall be deemed to have repeated the representation set forth in Section 8(f) of this Confirmation as of the date of such election). If Counterparty fails to give such notice to Dealer of its election by the end of that second Scheduled Trading Day, or if Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, then such failure or such determination, as the case may be, shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (1) Counterparty shall be deemed to be the sole Affected Party, (2) the Transaction shall be the sole Affected Transaction and (3) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. For the avoidance of doubt, the parties hereto agree and acknowledge that the occurrence of an Inversion Event shall not preclude the occurrence of one or more additional, subsequent Inversion Events, it being understood and agreed that any Price Adjustment described in clause (A) above and/or any payment described in clause (B) above shall be calculated without duplication in respect of any prior such Price Adjustment and/or payment.

Settlement Method:		For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement Method, but only if Counterparty shall have notified Dealer of the Relevant Settlement Method in the Notice of Exercise or Notice of Final Settlement Method, as applicable, for such Option.

Relevant Settlement Method:		In respect of any Option:

		(i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(a)(iv)(A) of the Supplemental Indenture (together with cash in lieu of fractional Shares) (such settlement method, “ Settlement in Shares ”), (B) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount less than USD 1,000 (such settlement method, “ Low Cash Combination Settlement ”) or (C) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement;

		(iii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note entirely in cash pursuant to Section 14.02(a)(iv)(B) of the Supplemental Indenture (such settlement method, “ Settlement in Cash ”), then the Relevant Settlement Method for such Option shall be Cash Settlement.

Net Share Settlement:		If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “ Net Share Settlement Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that, for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date, in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the Settlement Date for such Option.

		Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

Combination Settlement:		If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:

		(i) cash (the “ Combination Settlement Cash Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “ Daily Combination Settlement Cash Amount ”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

		(ii) Shares (the “ Combination Settlement Share Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “ Daily Combination Settlement Share Amount ”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day,

		the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

		provided that, for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date, in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the Combination Settlement Share Amount for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.

		Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

In no event will the Daily Option Value be less than zero.

Applicable Limit:		For any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder of the related Convertible Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note, in each case, as determined pursuant to the terms of the Supplemental Indenture, multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

Adjustments applicable to the Transaction:

Potential Adjustment Events:		Notwithstanding Section 11.2(e) of the Equity Definitions, a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in, and determined pursuant to, any Dilution Adjustment Provision, that would result in an adjustment under the Supplemental Indenture to the “Conversion Rate” or the composition of a “unit of Reference Property” or to any “Last Reported Sale Price,” “Daily VWAP,” “Daily Conversion Value” or “Daily Settlement Amount” (each as defined in the Supplemental Indenture). For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Supplemental Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section

		14.04(c) of the Supplemental Indenture or the fourth sentence of Section 14.04(d) of the Supplemental Indenture).

Method of Adjustment:		Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any Potential Adjustment Event, the Calculation Agent shall make an adjustment to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction corresponding to the adjustment(s) under the Supplemental Indenture; provided that, notwithstanding the foregoing, if the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 14.05 of the Supplemental Indenture or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will determine the adjustment to be made to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner; provided, further , that, notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment was made to any Convertible Note under the Supplemental Indenture because the relevant Holder (as such term is defined in the Supplemental Indenture) was deemed to be a record owner of the underlying Shares on the related Conversion Date, then the Calculation Agent shall make an adjustment, as determined by it, to the terms hereof in order to account for such Potential Adjustment Event.

Dilution Adjustment Provisions:		Sections 14.04(a), 14.04(b), 14.04(c), 14.04(d) and 14.04(e) and Section 14.05 of the Supplemental Indenture.

Extraordinary Events applicable to the Transaction:

Consequence of Merger Events:		Notwithstanding Section 12.2 of the Equity Definitions, upon the occurrence of a Merger Event, the Calculation Agent shall make a corresponding adjustment, to the extent an analogous adjustment is made under the Supplemental Indenture, to any one or more of the nature of the Shares, Strike Price, Number of Options, Option

		Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction; provided , however , that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to any Excluded Provision.

		If, in respect of any Merger Event to which the immediately preceding paragraph applies, the adjustments to be made in accordance with such paragraph would result in Counterparty being different from the issuer of the Shares, then with respect to such Merger Event, as a condition precedent to the adjustments contemplated in the immediately preceding paragraph, Dealer, the Issuer of the Affected Shares and the entity that will be the Issuer of the New Shares shall, prior to consummation of such Merger Event, have entered into such documentation containing agreements relating to “tacking” and “holding period” related considerations under U.S. securities law and credit exposure assumed by Dealer as the result Merger Event, as reasonably requested by Dealer that Dealer has determined, in its good faith, reasonable judgment, to be reasonably necessary or appropriate to allow Dealer to continue as a party to the Transaction, as adjusted under the immediately preceding paragraph, and to preserve its hedging or hedge unwind activities in connection with the Transaction in a manner compliant with applicable legal, and regulatory requirements, and if such conditions are not met or if the Calculation Agent determines that no adjustment under the immediately preceding paragraph will produce a commercially reasonable result, then the consequences set forth in Section 12.2(e)(ii) of the Equity Definitions shall apply to such Merger Event (as if Merger Event were as defined in Section 12.1(b) of the Equity Definitions).

Nationalization, Insolvency or Delisting:		Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors), such exchange or quotation system shall thereafter be deemed to be the Exchange.

Failure to Deliver:		Applicable

And, for the further avoidance of doubt, any such transactions or assets referred to in phrases (A) or (B) above must be available on commercially reasonable pricing terms. For purposes of the immediately preceding sentence, a de minimis increase in the cost of acquiring, establishing, re-establishing, substituting, maintaining, unwinding or disposing of any transaction(s) or asset(s) that the Hedging Party deems necessary to hedge the equity price risk of entering into and performing its obligations with respect to the relevant Transaction shall not give rise to a Hedging Disruption.”; and

		(ii) Section 12.9(b)(iii) of the Equity Definitions is hereby amended by inserting in the third line thereof, after the words “to terminate the Transaction”, the words “or a portion of the Transaction affected by such Hedging Disruption”.

Counterparty shall deliver to Dealer an opinion of counsel (subject to customary qualifications, assumptions and exceptions), dated as of the Trade Date, with respect to the matters set forth in Sections 8(a), 8(b), 8(c), 8(i) and 8(j) of this Confirmation. Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement. In addition, in connection with the entry into or consummation of any Inversion Transaction, Counterparty shall deliver to Dealer an opinion of counsel (subject to customary qualifications, assumptions and exceptions), dated as of the date of such Inversion Transaction, with respect to the matters set forth in Sections 8(a), 8(b), 8(c), 8(i) and 8(j) of this Confirmation (as if references therein to (i) “execute, deliver” were replaced with “assume”, (ii) “execution, delivery” and “execution and delivery” were replaced with “assumption” and (iii) “executed and delivered” were replaced with “assumed”); provided that no such opinion shall be required in respect of the matters set forth in Sections 8(i) and 8(j) of this Confirmation if the issuer of the Shares following such Inversion Transaction does not have a rights plan, “poison pill” or similar agreement in effect. “ Inversion Transaction ” means any Merger Event (as such term is defined in Section 12.1(b) of the Equity Definitions without regard to any amendment to such definition in this Confirmation), reincorporation of Counterparty, corporate inversion of Counterparty or similar transaction pursuant to which (x) the consideration for the Shares includes (or, at the option of a holder of

Shares, may include) shares of an entity or person that is not a corporation or is not organized under the laws of the United States, any State thereof or the District of Columbia, (y) the Counterparty following such Merger Event, reincorporation of Counterparty or corporate inversion of Counterparty is organized in a jurisdiction other than the United States, any State thereof or the District of Columbia or (z) the Counterparty following such Merger Event, reincorporation of Counterparty, corporate inversion of Counterparty or similar transaction will not be a corporation.

of the Convertible Notes. Counterparty shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.

(e) Transfer or Assignment .

(B) Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended);

(E) An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment;

(G) Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

and Dealer) that is equal to or better than Dealer’s credit rating from such agency on the date hereof, or (B) with Counterparty’s consent, to any other third party (including, without limitation, any affiliate of Dealer) organized in the United States with a rating for its long term, unsecured and unsubordinated indebtedness from either S&P or Moody’s (or, if both S&P and Moody’s ceases to rate such debt, by a substitute rating agency mutually agreed by Counterparty and Dealer) that is equal to or better than Dealer’s credit rating from such agency at the time of the transfer; provided , in each case, that if such transfer or assignment would result in any tax withholding obligation of the transferee in respect of any tax and such withholding tax, without application of this sentence, would not be an Indemnifiable Tax, such tax shall be treated as an Indemnifiable Tax if such withholding tax obligation would not have applied to Dealer or such withholding tax would have been an Indemnifiable Tax of Dealer. Without limiting the foregoing, no transfer or assignment by Dealer shall be permitted hereunder that would result in the occurrence of an Event of Default, Potential Event of Default or Termination Event. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “ Excess Ownership Position ”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party in accordance with the two, immediately preceding sentences on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “ Terminated Portion ”), such that following such partial termination no Excess Ownership Position exists. Dealer shall notify Counterparty of an Excess Ownership Position with respect to which it intends to seek a transfer or assignment as soon as reasonably practicable after becoming aware of such Excess Ownership Position. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “ Section 16 Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “ Option Equity Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“ Applicable Restrictions ”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “ Applicable Share Limit ” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations (other than any Form 13F, Schedule 13D or Schedule 13G filing under the Exchange Act) or other requirements (including

obtaining prior approval from any person or entity) of a Dealer Person, or would result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.

(iv) when specifying Staggered Settlement Dates pursuant to this Section 9(f), Dealer shall specify the fewest number of Staggered Settlement Dates as is practicable under the circumstances.

(g) Role of Agent . Dealer has appointed, as its agent, its indirect wholly-owned subsidiary, RBC Capital Markets, LLC (“ RBCCM ”), for purposes of conducting, on Dealer’s behalf, a business in privately negotiated transactions in options and other derivatives. Counterparty hereby is advised that Dealer, the principal and stated counterparty in such transactions, duly has authorized RBCCM to market, structure, negotiate, document, price, execute and hedge transactions in over-the-counter derivative products. RBCCM does not act as agent of Counterparty. For the avoidance of doubt, any performance by Dealer of its obligations hereunder solely to RBCCM shall not relieve Dealer of such obligations. RBCCM’s performance to Counterparty of Dealer’s obligations hereunder shall relieve Dealer of such obligations to the extent of such performance. Any performance by Counterparty of its obligations (including notice obligations) through or by means of RBCCM’s agency for Dealer shall constitute good performance of Counterparty’s obligations hereunder to Dealer.

(h) Additional Termination Events .

(i) Amendments to Equity Definitions .

following words therefor “or (C) the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master Agreement with respect to that Issuer.”

Share Termination Alternative:		If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable (the “ Share Termination Payment Date ”), in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.

Share Termination Delivery Property:		A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.

Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by

		the Calculation Agent in its good faith discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.

Share Termination Delivery Unit:		One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “ Exchange Property ”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.

Failure to Deliver:		Applicable

Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

		(i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(a)(iv)(A) of the Supplemental Indenture (together with cash in lieu of fractional Shares) (such settlement method, “ Settlement in Shares ”), (B) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount less than USD 1,000 (such settlement method, “ Low Cash Combination Settlement ”) or (C) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement;

		the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Supplemental Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section

Dilution Adjustment Provisions:		Sections 14.04(a), 14.04(b), 14.04(c), 14.04(d) and 14.04(e) and Section 14.05 of the Supplemental Indenture.

		If, in respect of any Merger Event to which the immediately preceding paragraph applies, the adjustments to be made in accordance with such paragraph would result in Counterparty being different from the issuer of the Shares, then with respect to such Merger Event, as a condition precedent to the adjustments contemplated in the immediately preceding paragraph, Dealer, the Issuer of the Affected Shares and the entity that will be the Issuer of the New Shares shall, prior to consummation of such Merger Event, have entered into such documentation containing agreements relating to “tacking” and “holding period” related considerations under U.S. securities law and credit exposure assumed by Dealer as the result Merger Event, as reasonably requested by Dealer that Dealer has determined, in its good faith, reasonable judgment, to be reasonably necessary or appropriate to allow Dealer to continue as a party to the Transaction, as adjusted under the immediately preceding paragraph, and to preserve its hedging or hedge unwind activities in connection with the Transaction in a manner compliant with applicable legal, and regulatory requirements, and if such conditions are not met or if the Calculation Agent determines that no adjustment under the immediately preceding paragraph will produce a commercially reasonable result, then the consequences set forth in Section 12.2(e)(ii) of the Equity Definitions shall apply to such Merger Event (as if Merger Event were as defined in Section 12.1(b) of the Equity Definitions).

Share Termination Alternative:		If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable (the “ Share Termination Payment Date ”), in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.

Share Termination Delivery Property:		A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.

Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its good faith discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of


		notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.

Share Termination Delivery Unit:		One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “ Exchange Property ”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.

Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities of similar size, in form and substance reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any commercially reasonable adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement).

(r) Notice of Certain Other Events . Counterparty covenants and agrees that:

Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. If, at any time following the occurrence of any Inversion Transaction, Dealer reasonably determines in its good faith judgment that (x) such Inversion Transaction has had a material adverse effect on Dealer’s rights and obligations under the Transaction or (y) Dealer would incur an increased (as compared with circumstances existing on the Trade Date) amount of tax, duty, expense or fee (other than brokerage commissions and excluding (I) any de minimis increased amount of tax, duty, expense or fee and (II) any such increased amount that is incurred solely due to the deterioration of the creditworthiness of Dealer), to (1) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the economic risk of entering into and performing its obligations with respect to the Transaction, or (2) realize, recover or remit the proceeds of any such transaction(s) or asset(s) (each of the events described in clause (x) and clause (y) above, an “ Inversion Event ”), then, in either case, Dealer shall give prompt notice to Counterparty of such Inversion Event. Concurrently with delivering such notice, Dealer shall give notice to Counterparty of a commercially reasonable Price Adjustment that Dealer determines, in its good faith, commercially reasonable judgment, appropriate to account for the economic effect on the Transaction of such Inversion Event and provide Counterparty with supporting documentation for such Price Adjustment (unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, in which case Dealer shall so notify Counterparty). Unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, within two Scheduled Trading Days of receipt of such notice, Counterparty shall notify Dealer that it elects to (A) agree to amend the Transaction to take into account such Price Adjustment or (B) pay Dealer an amount determined by Dealer (and in respect of which Dealer has provided to Counterparty supporting documentation) that corresponds to such Price Adjustment (and, in each case, Counterparty shall be deemed to have repeated the representation set forth in Section 8(f) of this Confirmation as of the date of such election). If Counterparty fails to give such notice to Dealer of its election by the end of that second Scheduled Trading Day, or if Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, then such failure or such determination, as the case may be, shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (1) Counterparty shall be deemed to be the sole Affected Party, (2) the Transaction shall be the sole Affected Transaction and (3) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. For the avoidance of doubt, the parties hereto agree and acknowledge that the occurrence of an Inversion Event shall not preclude the occurrence of one or more additional, subsequent Inversion Events, it being understood and agreed that any Price Adjustment described in clause (A) above and/or any payment described in clause (B) above shall be calculated without duplication in respect of any prior such Price Adjustment and/or payment.

Please confirm that the foregoing correctly sets forth the terms of the agreement between Dealer and Counterparty with respect to the Transaction, by manually signing this Confirmation or this page hereof as evidence of agreement to such terms and providing the other information requested herein and returning an executed copy to us.

(b) Repurchase Notices .

If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person, as a result of Company’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, such Indemnified Person shall promptly notify Company in writing.

(e) Transfer or Assignment . Company may not transfer any of its rights or obligations under the Transaction without the prior written consent of Dealer. Dealer may, (i) without Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any affiliate of Dealer, and (ii) with Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any third party; provided , in each case, that (x) Company will not be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Company would have been required to pay to Dealer in the absence of such transfer or assignment, and (y) Dealer shall have caused the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Company. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Warrant Equity Percentage exceeds 17.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “ Excess Ownership Position ”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Warrants to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “ Terminated Portion ”), such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a Terminated Portion, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Warrants equal to the number of Warrants underlying the Terminated Portion, (2) Company were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the Company shall be able to settle any corresponding obligation in cash or in Share Termination Delivery Units in its discretion in accordance with the provisions of Section 9(j).

The “ Warrant Equity Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Warrants and the Warrant Entitlement and (2) the aggregate number of Shares underlying any other warrants purchased by Dealer from Company, and (B) the denominator of which is the number of Shares outstanding. The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Company that are, in each case, applicable to ownership of Shares (“ Applicable Restrictions ”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “ Applicable Share Limit ” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations (other than any Form 13F, Schedule 13D or Schedule 13G filing under the Exchange Act) or other requirements (including obtaining prior approval from any person or entity but excluding any such requirement in respect of which prior approval has been obtained) of a Dealer Person, or would result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding. Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Company, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or make or receive such payment in cash, and otherwise to perform

Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Company only to the extent of any such performance.

(f) Dividends . If at any time during the period from and including the Effective Date, to and including the last Expiration Date, an ex-dividend date for a cash dividend occurs with respect to the Shares (an “ Ex-Dividend Date ”), then the Calculation Agent will adjust any of the Strike Price, Number of Warrants, Daily Number of Warrants and/or any other variable relevant to the exercise, settlement or payment of the Transaction to preserve the fair value of the Warrants to Dealer after taking into account such dividend.

(g) Role of Agent. Each party agrees and acknowledges that (i) J.P. Morgan Securities LLC, an affiliate of JPMorgan (“ JPMS ”), has acted solely as agent and not as principal with respect to the Transaction and (ii) JPMS has no obligation or liability, by way of guaranty, endorsement or otherwise, in any manner in respect of the Transaction (including, if applicable, in respect of the settlement thereof). Each party agrees it will look solely to the other party (or any guarantor in respect thereof) for performance of such other party’s obligations under the Transaction.

(E) Dealer, despite using commercially reasonable efforts, is unable or reasonably determines, based on the advice of counsel, that it is impractical or illegal, to hedge its exposure with respect to the Transaction in the public market without registration under the Securities Act or as a result of any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer).

(i) No Collateral or Setoff . Notwithstanding any provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Company hereunder are not and shall not be secured by any collateral.

Share Termination Alternative:		If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “ Share Termination Payment Date ”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, subject to Section 9(k)(i) below, in satisfaction, subject to Section 9(k)(ii) below, of the relevant Payment Obligation, in the manner reasonably requested by Dealer free of payment.

Share Termination Delivery Property:		A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the relevant Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price (without giving effect to any discount pursuant to Section 9(k)(i)).

Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its discretion by commercially reasonable means. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in Section 9(k)(i) below, the Share Termination Unit Price shall be determined by the discounted price applicable to such Share Termination Delivery Units. In the case of a Registration Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as

		set forth in Section 9(k)(ii) below, notwithstanding the foregoing, the Share Termination Unit Price shall be the Settlement Price on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable. The Calculation Agent shall notify Company of the Share Termination Unit Price at the time of notification of such Payment Obligation to Company or, if applicable, at the time the discounted price applicable to the relevant Share Termination Units is determined pursuant to Section 9(k)(i).

Share Termination Delivery Unit:		One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “ Exchange Property ”), a unit consisting of the type and amount of Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event. If such Nationalization, Insolvency or Merger Event involves a choice of Exchange Property to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.

Failure to Deliver:		Inapplicable

Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11 and 9.12 (as modified above) of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

(k) Registration/Private Placement Procedures . If, in the reasonable opinion of Dealer, based on the advice of counsel, following any delivery of Shares or Share Termination Delivery Property to Dealer hereunder, such Shares or Share Termination Delivery Property would be in the hands of Dealer subject to any applicable restrictions with respect to any registration or qualification requirement or prospectus delivery requirement for such Shares or Share Termination Delivery Property pursuant to any applicable federal or state securities law (including, without limitation, any such requirement arising under Section 5 of the Securities Act as a result of such Shares or Share Termination Delivery Property being “restricted securities”, as such term is defined in Rule 144 under the Securities Act, or as a result of the sale of such Shares or Share Termination Delivery Property being subject to paragraph (c) of Rule 145 under the Securities Act) (such Shares or Share Termination Delivery Property, “ Restricted Shares ”), then delivery of such Restricted Shares shall be effected pursuant to either clause (i) or (ii) below at the election of Company, unless Dealer waives the need for registration/private placement procedures set forth in (i) and (ii) below. Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants exercised or deemed exercised on any Expiration Date, Company shall elect, prior to the first Settlement Date for the first applicable Expiration Date, a Private Placement Settlement or Registration Settlement for all deliveries of Restricted Shares for all such Expiration Dates which election shall be applicable to all remaining Settlement Dates for such Warrants and the procedures in clause (i) or clause (ii) below shall apply for all such delivered Restricted Shares on an aggregate basis

commencing after the final Settlement Date for such Warrants. The Calculation Agent shall make reasonable adjustments to settlement terms and provisions under this Confirmation to reflect a single Private Placement or Registration Settlement for such aggregate Restricted Shares delivered hereunder.

(i) If Company elects to settle the Transaction pursuant to this clause (i) (a “ Private Placement Settlement ”), then delivery of Restricted Shares by Company shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Dealer; provided that Company may not elect a Private Placement Settlement if, on the date of its election, it has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(2) of the Securities Act for the sale by Company to Dealer (or any affiliate designated by Dealer) of the Restricted Shares or the exemption pursuant to Section 4(1) or Section 4(3) of the Securities Act for resales of the Restricted Shares by Dealer (or any such affiliate of Dealer). The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Restricted Shares by Dealer), opinions and certificates, and such other documentation as is customary for private placement agreements, all reasonably acceptable to Dealer. In the case of a Private Placement Settlement, Dealer shall determine the appropriate discount to the Share Termination Unit Price (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or any Settlement Price (in the case of settlement of Shares pursuant to Section 2 above) applicable to such Restricted Shares in a commercially reasonable manner and appropriately adjust the number of such Restricted Shares to be delivered to Dealer hereunder, which discount shall only take into account the illiquidity resulting from the fact that the Restricted Shares will not be registered for resale and any commercially reasonable fees and expenses of Dealer (and any affiliate thereof) in connection with such resale. Notwithstanding anything to the contrary in the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Exchange Business Day following notice by Dealer to Company, of such applicable discount and the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Share Termination Payment Date (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or on the Settlement Date for such Restricted Shares (in the case of settlement in Shares pursuant to Section 2 above).

(ii) If Company elects to settle the Transaction pursuant to this clause (ii) (a “ Registration Settlement ”), then Company shall promptly (but in any event no later than the beginning of the Resale Period) file and use its reasonable best efforts to make effective under the Securities Act a registration statement or supplement or amend an outstanding registration statement in form and substance reasonably satisfactory to Dealer, to cover the resale of such Restricted Shares in accordance with customary resale registration procedures, including covenants, conditions, representations, underwriting discounts (if applicable), commissions (if applicable), indemnities due diligence rights, opinions and certificates, and such other documentation as is customary for equity resale underwriting agreements, all reasonably acceptable to Dealer. If Dealer, in its sole reasonable discretion, is not satisfied with such procedures and documentation Private Placement Settlement shall apply. If Dealer is satisfied with such procedures and documentation, it shall sell the Restricted Shares pursuant to such registration statement during a period (the “ Resale Period ”) commencing on the Exchange Business Day following delivery of such Restricted Shares (which, for the avoidance of doubt, shall be (x) the Share Termination Payment Date in case of settlement in Share Termination Delivery Units pursuant to Section 9(j) above or (y) the Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants) and ending on the earliest of (i) the Exchange Business Day on which Dealer completes the sale of all Restricted Shares or, in the case of settlement of Share Termination Delivery Units, a sufficient number of Restricted Shares so that the realized net proceeds of such sales equals or exceeds the Payment Obligation (as defined above), (ii) the date upon which all Restricted Shares have been sold or transferred pursuant to Rule 144 (or similar provisions then in force) or Rule 145(d)(2) (or any similar provision then in force) under the Securities Act and (iii) the date upon which all Restricted Shares may be sold or transferred by a non-affiliate pursuant to Rule 144 (or any similar provision then in force) or Rule 145(d)(2) (or any similar provision then in force)

under the Securities Act, provided that Dealer shall use commercially reasonable efforts, taking into account prevailing market conditions, promptly to complete the sale of all Restricted Shares. If the Payment Obligation exceeds the realized net proceeds from such resale, Company shall transfer to Dealer by the open of the regular trading session on the Exchange on the Exchange Trading Day immediately following such resale the amount of such excess (the “ Additional Amount ”) in cash or in a number of Shares (“ Make-whole Shares ”) in an amount that, based on the Settlement Price on such day (as if such day was the “Valuation Date” for purposes of computing such Settlement Price), has a dollar value equal to the Additional Amount. The Resale Period shall continue to enable the sale of the Make-whole Shares, provided that Company shall be permitted to suspend or delay any Resale Period for customary “black-out” periods. If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration Settlement shall apply. This provision shall be applied successively until the Additional Amount is equal to zero. For the avoidance of doubt, Dealer shall cease selling Make-whole Shares, and the Resale Period shall terminate, when the Additional Amount has been reduced to zero, and if at such time, Dealer holds any excess Make-whole Shares, such Shares shall promptly be returned to Company. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Number of Shares.

(iii) Without limiting the generality of the foregoing, Company agrees that (A) any Restricted Shares delivered to Dealer may be transferred by and among Dealer and its affiliates and Company shall effect such transfer without any further action by Dealer and (B) after the period of 6 months from the Trade Date (or 1 year from the Trade Date if, at such time, informational requirements of Rule 144(c) under the Securities Act are not satisfied with respect to Company) has elapsed in respect of any Restricted Shares delivered to Dealer, Company shall promptly remove, or cause the transfer agent for such Restricted Shares to remove, any legends referring to any such restrictions or requirements from such Restricted Shares upon request by Dealer (or such affiliate of Dealer) to Company or such transfer agent, without any requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Dealer (or such affiliate of Dealer). Notwithstanding anything to the contrary herein, to the extent the provisions of Rule 144 of the Securities Act or any successor rule are amended, or the applicable interpretation thereof by the Securities and Exchange Commission or any court change after the Trade Date, the agreements of Company herein shall be deemed modified to the extent necessary, in the opinion of outside counsel of Company, to comply with Rule 144 of the Securities Act, as in effect at the time of delivery of the relevant Shares or Share Termination Delivery Property.

(iv) If the Private Placement Settlement or the Registration Settlement shall not be effected as set forth in clauses (i) or (ii), as applicable, then failure to effect such Private Placement Settlement or such Registration Settlement shall constitute an Event of Default with respect to which Company shall be the Defaulting Party.

(l) Limit on Beneficial Ownership . Notwithstanding any other provisions hereof, Dealer may not exercise any Warrant hereunder or be entitled to take delivery of any Shares deliverable hereunder , and Automatic Exercise shall not apply with respect to any Warrant hereunder, to the extent (but only to the extent) that, after such receipt of any Shares upon the exercise of such Warrant or otherwise hereunder, (i) the Section 16 Percentage would exceed 7.5%, or (ii) the Share Amount would exceed the Applicable Share Limit. Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery, (i) the Section 16 Percentage would exceed 7.5%, or (ii) the Share Amount would exceed the Applicable Share Limit. If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Company’s obligation to make such delivery shall not be extinguished and Company shall make such delivery as promptly as practicable after, but in no event later than one Business Day after, Dealer gives notice to Company that, after such delivery, (i) the Section 16 Percentage would not exceed 7.5%, and (ii) the Share Amount would not exceed the Applicable Share Limit.

(n) Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the Transaction. Each party (i) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

(o) Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Company and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Company relating to such tax treatment and tax structure.

(p) Maximum Share Delivery .

(ii) In the event Company shall not have delivered to Dealer the full number of Shares or Restricted Shares otherwise deliverable by Company to Dealer pursuant to the terms of the Transaction because Company has insufficient authorized but unissued Shares (such deficit, the “ Deficit Shares ”), Company shall be continually obligated to deliver, from time to time, Shares or Restricted Shares, as the case may be, to Dealer until the full number of Deficit Shares have been delivered pursuant to this Section 9(p)(ii), when, and to the extent that, (A) Shares are repurchased, acquired or otherwise received by Company or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (B) authorized and unissued Shares previously reserved for issuance in respect of other transactions become no longer so reserved or (C) Company additionally authorizes any unissued Shares that are not reserved for other transactions; provided that in no event shall Company deliver any Shares or Restricted Shares to Dealer pursuant to this Section 9(p)(ii) to the extent that such delivery would cause the aggregate number of Shares and Restricted Shares delivered to Dealer to exceed the Maximum Number of Shares. Company shall immediately notify Dealer of the occurrence of any of the foregoing events (including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares or Restricted Shares, as the case may be, to be delivered) and promptly deliver such Shares or Restricted Shares, as the case may be, thereafter.

(iii) Notwithstanding anything to the contrary in the Agreement, this Confirmation or the Equity Definitions, the Maximum Number of Shares shall not be adjusted on account of any event that (x) constitutes a Potential Adjustment Event solely on account of Section 11.2(e)(vii) of the Equity Definitions and (y) is not an event within Company’s control.

(q) Right to Extend. Dealer may postpone or add, in whole or in part, any Expiration Date or any other date of valuation or delivery with respect to some or all of the relevant Warrants (in which event the Calculation Agent shall make appropriate adjustments to the Daily Number of Warrants with respect to one or more Expiration Dates) if Dealer reasonably determines (i) in its commercially reasonable judgment, that such extension is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or (ii) based on the advice of counsel, to enable Dealer to effect purchases of Shares in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Issuer or an affiliated purchaser of Issuer, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer.

(r) Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Company with respect to the Transaction that are senior to the claims of common stockholders of Company in any United States bankruptcy proceedings of Company; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Company of its obligations and agreements with respect to the Transaction; p rovided , further , that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.

(t) Wall Street Transparency and Accountability Act . In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“ WSTAA ”), the parties hereby agree that neither the enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as defined in the Agreement)).

(u) Agreements and Acknowledgements Regarding Hedging . Company understands, acknowledges and agrees that: (A) at any time on and prior to the last Expiration Date, Dealer and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be active in the market for Shares other than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in securities of Issuer shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Settlement Prices; and (D) any market activities of Dealer and its affiliates with respect to Shares may affect the market price and volatility of Shares, as well as the Settlement Prices, each in a manner that may be adverse to Company.

(v) Early Unwind . In the event the sale of the “Firm Securities” (as defined in the Underwriting Agreement) is not consummated with the Underwriters for any reason, or Company fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment Date or such later date the “ Early Unwind Date ”), the Transaction shall automatically terminate (the “ Early Unwind ”), on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Company under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date. Each of Dealer and Company represents and acknowledges to the other that upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

(w) Payment by Dealer . In the event that (i) an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Dealer owes to Company an amount calculated under Section 6(e) of the Agreement, or (ii) Dealer owes to Company, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero.

(x) Inversion Transaction . Company shall not enter into or consummate any Inversion Transaction unless the successor Company immediately following such Inversion Transaction repeats to Dealer immediately following such Inversion Transaction the representations and warranties set forth in Sections 8(a), 8(b), 8(c), 8(d), 8(j) and 8(k) of this Confirmation (as if references therein to (i) “execute, deliver” were replaced with “assume”, (ii) “execution, delivery” and “execution and delivery” were replaced with “assumption” and (iii) “executed and delivered” were replaced with “assumed”). Notwithstanding anything to the contrary in this Confirmation if Company enters into or consummates any Inversion Transaction pursuant to which Company following such Inversion Transaction is organized under the laws of a jurisdiction other than the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, then such Inversion Transaction shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Company shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. If, at any time following the occurrence of any Inversion Transaction, Dealer reasonably determines in its good faith judgment that (x) such Inversion Transaction has had a material adverse effect on Dealer’s rights and obligations under the Transaction or (y) Dealer would incur an increased (as compared with circumstances existing on the Trade Date) amount of tax, duty, expense or fee (other than brokerage commissions and excluding (I) any de minimis increased amount of tax, duty, expense or fee and (II) any such increased amount that is incurred solely due to the deterioration of the creditworthiness of Dealer), to (1) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the economic risk of entering into and performing its obligations with respect to the Transaction, or (2) realize, recover or remit the proceeds of any such transaction(s) or asset(s) (each of the events described in clause (x) and clause (y) above, an “ Inversion Event ”), then, in either case, Dealer shall give prompt notice to Company of such Inversion Event. Concurrently with delivering such notice, Dealer shall give notice to Company of a commercially reasonable Price Adjustment that Dealer determines, in its good faith, commercially reasonable judgment, appropriate to account for the economic effect on the Transaction of such Inversion Event and provide Company with supporting documentation for such Price Adjustment (unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, in which case Dealer shall so notify Company). Unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, within two Scheduled Trading Days of receipt of such notice, Company shall notify Dealer that it elects to (A) agree to amend the Transaction to take into account such Price Adjustment or (B) pay Dealer an amount determined by Dealer (and in respect of which Dealer has provided to Company supporting documentation) that corresponds to such Price Adjustment (and, in each case, Company shall be deemed to have repeated the representation set forth in Section 8(g) of this Confirmation as of the date of such election). If Company fails to give such notice to Dealer of its election by the end of that second Scheduled Trading Day, or if Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, then such failure or such determination, as the case may be, shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (1) Company shall be deemed to be the sole Affected Party, (2) the Transaction shall be the sole Affected Transaction and (3) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. For the avoidance of doubt, the parties hereto agree and acknowledge that the occurrence of an Inversion Event shall not preclude the occurrence of one or more additional, subsequent Inversion Events, it being understood and agreed that any Price Adjustment described in clause (A) above and/or any payment described in clause (B) above shall be calculated without duplication in respect of any prior such Price Adjustment and/or payment.

Consequence of Merger Events:

Merger Event:		Applicable; provided that if an event occurs that constitutes both a Merger Event under Section 12.1(b) of the Equity Definitions and an Additional Termination Event under Section 9(h)(ii)(B) of this Confirmation, Section 9(h)(ii)(B) will apply.

Consequence of Tender Offers:

Tender Offer:		Applicable; provided that Section 12.1(d) of the Equity Definitions is hereby amended by replacing “10%” with “25%” in the third line thereof; provided further , that if an event occurs that constitutes both a Tender Offer under Section 12.1(d) of the Equity Definitions and Additional Termination Event under Section 9(h)(ii)(A) of this Confirmation, Section 9(h)(ii)(A) will apply.

		period of time, including, without limitation, the period from the Announcement Event to the relevant Announcement Event Adjustment Date).

Company shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to the matters set forth in Sections 8(a), 8(b), 8(c), 8(d), 8(j) and 8(k) of this Confirmation. Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement. In addition, in connection with the entry into or consummation of any Inversion Transaction (as defined below), Company shall deliver to Dealer an opinion of counsel (subject to customary qualifications, assumptions and exceptions), dated as of the date of such Inversion Transaction, with respect to the matters set forth in Sections 8(a), 8(b), 8(c), 8(d), 8(j) and 8(k) of this Confirmation (as if references therein to (i) “execute, deliver” were replaced with “assume”, (ii) “execution, delivery” and “execution and delivery” were replaced with “assumption” and (iii) “executed and delivered” were replaced with “assumed”); provided that no such opinion shall be required in respect of the matters set forth in Sections 8(j) and 8(k) of this Confirmation if the issuer of the Shares following such Inversion Transaction does not have a rights plan, “poison pill” or similar agreement in effect. “ Inversion Transaction ” means any Merger Event, reincorporation of Company, corporate inversion of Company or similar transaction pursuant to which (x) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation or is not organized under the laws of the United States, any State thereof or the District of Columbia, (y) the

Company following such Merger Event, reincorporation of Company or corporate inversion of Company is organized in a jurisdiction other than the United States, any State thereof or the District of Columbia or (z) the Company following such Merger Event, reincorporation of Company, corporate inversion of Company or similar transaction will not be a corporation.

(c) Regulation M . Company is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), of any securities of Company, other than (i) a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M and (ii) the distribution of up to USD 200,00,000 of Convertible Senior Notes due 2019. Company shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.

transfer or assign all or any part of its rights or obligations under the Transaction to any affiliate of Dealer, and (ii) with Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any third party; provided , in each case, that (x) Company will not be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Company would have been required to pay to Dealer in the absence of such transfer or assignment, and (y) Dealer shall have caused the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Company. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Warrant Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “ Excess Ownership Position ”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Warrants to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “ Terminated Portion ”), such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a Terminated Portion, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Warrants equal to the number of Warrants underlying the Terminated Portion, (2) Company were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the Company shall be able to settle any corresponding obligation in cash or in Share Termination Delivery Units in its discretion in accordance with the provisions of Section 9(j). The “ Section 16 Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “ Warrant Equity Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Warrants and the Warrant Entitlement and (2) the aggregate number of Shares underlying any other warrants purchased by Dealer from Company, and (B) the denominator of which is the number of Shares outstanding. The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Company that are, in each case, applicable to ownership of Shares (“ Applicable Restrictions ”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “ Applicable Share Limit ” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations (other than any Form 13F, Schedule 13D or Schedule 13G filing under the Exchange Act) or other requirements (including obtaining prior approval from any person or entity but excluding any such requirement in respect of which prior approval has been obtained) of a Dealer Person, or would result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding. Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Company, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Company only to the extent of any such performance.

(g) Role of Agent. Dealer has appointed, as its agent, its indirect wholly-owned subsidiary, RBC Capital Markets, LLC (“ RBCCM ”), for purposes of conducting, on Dealer’s behalf, a business in privately

negotiated transactions in options and other derivatives. Company hereby is advised that Dealer, the principal and stated counterparty in such transactions, duly has authorized RBCCM to market, structure, negotiate, document, price, execute and hedge transactions in over-the-counter derivative products. RBCCM does not act as agent of Company. For the avoidance of doubt, any performance by Dealer of its obligations hereunder solely to RBCCM shall not relieve Dealer of such obligations. RBCCM’s performance to Company of Dealer’s obligations hereunder shall relieve Dealer of such obligations to the extent of such performance. Any performance by Company of its obligations (including notice obligations) through or by means of RBCCM’s agency for Dealer shall constitute good performance of Company’s obligations hereunder to Dealer.

(h) Additional Provisions .

(i) Amendments to the Equity Definitions:

(E) Section 12.9(b)(iv) of the Equity Definitions is hereby amended by:

(x) deleting (1) subsection (A) in its entirety, (2) the phrase “or (B)” following subsection (A) and (3) the phrase “in each case” in subsection (B); and

(y) replacing the phrase “neither the Non-Hedging Party nor the Lending Party lends Shares” with the phrase “such Lending Party does not lend Shares” in the penultimate sentence.

(F) Section 12.9(b)(v) of the Equity Definitions is hereby amended by:

(x) adding the word “or” immediately before subsection “(B)” and deleting the comma at the end of subsection (A); and

(B) Consummation of (I) any recapitalization, reclassification or change of the Shares (other than changes resulting from a subdivision, combination or changes solely in par value) as a result of which the Shares would be converted into, or exchanged for, stock, other securities, other property or assets or (II) any share exchange, consolidation or merger of Company pursuant to which the Shares will be converted into cash, securities or other property or assets or (III) any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of Company and its subsidiaries, taken as a whole, to any person other than one of Company’s subsidiaries. Notwithstanding the foregoing, any transaction or transactions set forth in this clause (B) shall not constitute an Additional Termination Event if (x) at least 90% of the consideration received or to be received by holders of the Shares, excluding cash payments for fractional Shares and cash payments made pursuant to dissenters’ appraisal rights, in connection with such transaction or transactions consists of shares of common stock, American depositary receipts, ordinary shares or other common equity interests, in each case,

that are listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions, and (y) as a result of such transaction or transactions, the Shares will consist of such consideration, excluding cash payments for fractional Shares and cash payments made pursuant to dissenters’ appraisal rights.

(j) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events .

Termination Event in which Company is the Affected Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Company’s control), and if Company would owe any amount to Dealer pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “ Payment Obligation ”), then Company shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Company gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not apply, (b) Company remakes the representation set forth in Section 8(g) as of the date of such election and (c) Dealer agrees, in its sole discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.

Share Termination Alternative:		If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “ Share Termination Payment Date ”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, subject to Section 9(k)(i) below, in satisfaction, subject to Section 9(k)(ii) below, of the relevant Payment Obligation, in the manner reasonably requested by Dealer free of payment.

Share Termination Delivery Property:		A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the relevant Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price (without giving effect to any discount pursuant to Section 9(k)(i)).

Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its discretion by commercially reasonable means. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in Section 9(k)(i) below, the Share Termination Unit Price shall be determined by the discounted price applicable to such Share Termination Delivery Units. In the case of a Registration Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as set forth in Section 9(k)(ii) below, notwithstanding the foregoing, the Share Termination Unit Price shall be the Settlement Price on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable.

		The Calculation Agent shall notify Company of the Share Termination Unit Price at the time of notification of such Payment Obligation to Company or, if applicable, at the time the discounted price applicable to the relevant Share Termination Units is determined pursuant to Section 9(k)(i).

Share Termination Delivery Unit:		One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “ Exchange Property ”), a unit consisting of the type and amount of Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event. If such Nationalization, Insolvency or Merger Event involves a choice of Exchange Property to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.

Failure to Deliver:		Inapplicable

Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11 and 9.12 (as modified above) of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

(i) If Company elects to settle the Transaction pursuant to this clause (i) (a “ Private Placement Settlement ”), then delivery of Restricted Shares by Company shall be effected in customary

private placement procedures with respect to such Restricted Shares reasonably acceptable to Dealer; provided that Company may not elect a Private Placement Settlement if, on the date of its election, it has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(2) of the Securities Act for the sale by Company to Dealer (or any affiliate designated by Dealer) of the Restricted Shares or the exemption pursuant to Section 4(1) or Section 4(3) of the Securities Act for resales of the Restricted Shares by Dealer (or any such affiliate of Dealer). The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Restricted Shares by Dealer), opinions and certificates, and such other documentation as is customary for private placement agreements, all reasonably acceptable to Dealer. In the case of a Private Placement Settlement, Dealer shall determine the appropriate discount to the Share Termination Unit Price (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or any Settlement Price (in the case of settlement of Shares pursuant to Section 2 above) applicable to such Restricted Shares in a commercially reasonable manner and appropriately adjust the number of such Restricted Shares to be delivered to Dealer hereunder, which discount shall only take into account the illiquidity resulting from the fact that the Restricted Shares will not be registered for resale and any commercially reasonable fees and expenses of Dealer (and any affiliate thereof) in connection with such resale. Notwithstanding anything to the contrary in the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Exchange Business Day following notice by Dealer to Company, of such applicable discount and the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Share Termination Payment Date (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or on the Settlement Date for such Restricted Shares (in the case of settlement in Shares pursuant to Section 2 above).

such excess (the “ Additional Amount ”) in cash or in a number of Shares (“ Make-whole Shares ”) in an amount that, based on the Settlement Price on such day (as if such day was the “Valuation Date” for purposes of computing such Settlement Price), has a dollar value equal to the Additional Amount. The Resale Period shall continue to enable the sale of the Make-whole Shares, provided that Company shall be permitted to suspend or delay any Resale Period for customary “black-out” periods. If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration Settlement shall apply. This provision shall be applied successively until the Additional Amount is equal to zero. For the avoidance of doubt, Dealer shall cease selling Make-whole Shares, and the Resale Period shall terminate, when the Additional Amount has been reduced to zero, and if at such time, Dealer holds any excess Make-whole Shares, such Shares shall promptly be returned to Company. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Number of Shares.

(m) Share Deliveries . Notwithstanding anything to the contrary herein, Company agrees that any delivery of Shares or Share Termination Delivery Property shall be effected by book-entry transfer through the facilities of DTC, or any successor depositary, if at the time of delivery, such class of Shares or class of Share Termination Delivery Property is in book-entry form at DTC or such successor depositary.

or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

(p) Maximum Share Delivery .

any Inversion Transaction pursuant to which Company following such Inversion Transaction is organized under the laws of a jurisdiction other than the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, then such Inversion Transaction shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Company shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. If, at any time following the occurrence of any Inversion Transaction, Dealer reasonably determines in its good faith judgment that (x) such Inversion Transaction has had a material adverse effect on Dealer’s rights and obligations under the Transaction or (y) Dealer would incur an increased (as compared with circumstances existing on the Trade Date) amount of tax, duty, expense or fee (other than brokerage commissions and excluding (I) any de minimis increased amount of tax, duty, expense or fee and (II) any such increased amount that is incurred solely due to the deterioration of the creditworthiness of Dealer), to (1) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the economic risk of entering into and performing its obligations with respect to the Transaction, or (2) realize, recover or remit the proceeds of any such transaction(s) or asset(s) (each of the events described in clause (x) and clause (y) above, an “ Inversion Event ”), then, in either case, Dealer shall give prompt notice to Company of such Inversion Event. Concurrently with delivering such notice, Dealer shall give notice to Company of a commercially reasonable Price Adjustment that Dealer determines, in its good faith, commercially reasonable judgment, appropriate to account for the economic effect on the Transaction of such Inversion Event and provide Company with supporting documentation for such Price Adjustment (unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, in which case Dealer shall so notify Company). Unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, within two Scheduled Trading Days of receipt of such notice, Company shall notify Dealer that it elects to (A) agree to amend the Transaction to take into account such Price Adjustment or (B) pay Dealer an amount determined by Dealer (and in respect of which Dealer has provided to Company supporting documentation) that corresponds to such Price Adjustment (and, in each case, Company shall be deemed to have repeated the representation set forth in Section 8(g) of this Confirmation as of the date of such election). If Company fails to give such notice to Dealer of its election by the end of that second Scheduled Trading Day, or if Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, then such failure or such determination, as the case may be, shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (1) Company shall be deemed to be the sole Affected Party, (2) the Transaction shall be the sole Affected Transaction and (3) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. For the avoidance of doubt, the parties hereto agree and acknowledge that the occurrence of an Inversion Event shall not preclude the occurrence of one or more additional, subsequent Inversion Events, it being understood and agreed that any Price Adjustment described in clause (A) above and/or any payment described in clause (B) above shall be calculated without duplication in respect of any prior such Price Adjustment and/or payment.

This Confirmation may be executed in several counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

Company hereby agrees to check this Confirmation and to confirm that the foregoing correctly sets forth the terms of the Transaction by signing in the space provided below and returning to Dealer a facsimile of the fully-executed Confirmation to Dealer. Originals shall be provided for your execution upon your request.

We are very pleased to have executed the Transaction with you and we look forward to completing other transactions with you in the near future.

(e) Transfer or Assignment . Company may not transfer any of its rights or obligations under the Transaction without the prior written consent of Dealer. Dealer may, (i) without Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any affiliate of Dealer, and (ii) with Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any third party; provided , in each case, that (x) Company will not be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Company would have been required to pay to Dealer in the absence of such transfer or assignment, and (y) Dealer shall have caused the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Company. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Warrant Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “ Excess Ownership Position ”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Warrants to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “ Terminated Portion ”), such that following such partial termination no Excess Ownership Position exists.

The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Company that are, in each case, applicable to ownership of Shares (“ Applicable Restrictions ”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion.

(y) replacing the phrase “neither the Non-Hedging Party nor the Lending Party lends Shares” with the phrase “such Lending Party does not lend Shares” in the penultimate sentence.

(F) Section 12.9(b)(v) of the Equity Definitions is hereby amended by:

(x) adding the word “or” immediately before subsection “(B)” and deleting the comma at the end of subsection (A); and

(j) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events .

Share Termination Alternative:		If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “ Share Termination Payment Date ”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, subject to Section 9(k)(i) below, in satisfaction, subject to Section 9(k)(ii) below, of the relevant Payment Obligation, in the manner reasonably requested by Dealer free of payment.

Share Termination Delivery
Property:		A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the relevant Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price (without giving effect to any discount pursuant to Section 9(k)(i)).

Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its discretion by commercially reasonable means. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in Section 9(k)(i) below, the Share Termination Unit Price shall be determined by the discounted price applicable to such Share Termination Delivery Units. In the case of a Registration Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as set forth in Section 9(k)(ii) below, notwithstanding the foregoing, the Share Termination Unit Price shall be the Settlement Price on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable.

		The Calculation Agent shall notify Company of the Share Termination Unit Price at the time of notification of such Payment Obligation to Company or, if applicable, at the time the discounted price applicable to the relevant Share Termination Units is determined pursuant to Section 9(k)(i).

Share Termination Delivery Unit:		One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “ Exchange Property ”), a unit consisting of the type and amount of Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event. If such Nationalization, Insolvency or Merger Event involves a choice of Exchange Property to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.

Failure to Deliver:		Inapplicable

Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11 and 9.12 (as modified above) of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

(i) If Company elects to settle the Transaction pursuant to this clause (i) (a “ Private Placement Settlement ”), then delivery of Restricted Shares by Company shall be effected in customary

(p) Maximum Share Delivery .

Relevant Settlement Method:		In respect of any Option:

		(i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(a)(iv)(A) of the Supplemental Indenture (together with cash in lieu of fractional Shares) (such settlement method, “ Settlement in Shares ”), (B) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount less than USD 1,000 (such settlement method, “ Low Cash Combination Settlement ”) or (C) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash

		Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement;

		(ii) Shares (the “ Combination Settlement Share Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “ Daily Combination Settlement Share Amount ”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

		provided that, for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date, in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the Combination Settlement Share Amount for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.

For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Supplemental Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section 14.04(c) of the Supplemental Indenture or the fourth sentence of Section 14.04(d) of the Supplemental Indenture).

Method of Adjustment:		Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any Potential Adjustment Event, the Calculation Agent shall make an adjustment to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction corresponding to the adjustment(s) under the Supplemental Indenture; provided that, notwithstanding the foregoing, if the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 14.05 of the Supplemental Indenture or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will determine the adjustment to be made to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner; provided, further , that, notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment was made to any Convertible Note under the Supplemental Indenture because the relevant Holder (as such term is defined in the Supplemental Indenture) was deemed to be a record owner of the underlying Shares on the related Conversion Date, then the Calculation Agent shall make an adjustment, as determined by it, to the terms hereof in order to account for such Potential Adjustment Event.

Dilution Adjustment Provisions:		Sections 14.04(a), 14.04(b), 14.04(c), 14.04(d) and 14.04(e) and Section 14.05 of the Supplemental Indenture.

If, in respect of any Merger Event to which the immediately preceding paragraph applies, the adjustments to be made in accordance with such paragraph would result in Counterparty being different from the issuer of the Shares, then with respect to such Merger Event, as a condition precedent to the adjustments contemplated in the immediately preceding paragraph, Dealer, the Issuer of the Affected Shares and the entity that will be the Issuer of the New Shares shall, prior to consummation of such Merger Event, have entered into such documentation containing agreements relating to “tacking” and “holding period” related considerations under U.S. securities law and credit exposure assumed by Dealer as the result Merger Event, as reasonably requested by Dealer that Dealer has determined, in its good faith, reasonable judgment, to be reasonably necessary or appropriate to allow Dealer to continue as a party to the Transaction, as adjusted under the immediately preceding paragraph, and to preserve its hedging or hedge unwind activities in connection with the Transaction in a manner compliant with applicable legal, and regulatory requirements, and if such conditions are not met or if the Calculation Agent determines that no adjustment under the immediately preceding paragraph will produce a commercially reasonable result, then the consequences set forth in Section 12.2(e)(ii) of the Equity Definitions shall apply to such Merger Event (as if Merger Event were as defined in Section 12.1(b) of the Equity Definitions).

Nationalization, Insolvency or Delisting:		Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors), such exchange or quotation system shall thereafter be deemed to be the Exchange.

And, for the further avoidance of doubt, any such transactions or assets referred to in phrases (A) or (B) above must be available on commercially reasonable pricing terms. For purposes of the immediately preceding sentence, a de minimis increase in the cost of acquiring, establishing, re-establishing, substituting, maintaining, unwinding or disposing of any transaction(s) or asset(s) that the Hedging Party deems necessary to hedge the equity price risk of entering into and performing its obligations with respect to the relevant Transaction shall not give rise to a Hedging Disruption.”; and

		(ii) Section 12.9(b)(iii) of the Equity Definitions is hereby amended by inserting in the third line thereof, after the words “to terminate the Transaction”, the words “or a portion of the Transaction affected by such Hedging Disruption”.

If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

Shares that Dealer and each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “ Option Equity Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“ Applicable Restrictions ”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion.

Upon receipt of any such Notice of Exercise, Dealer shall designate an Exchange Business Day following such Additional Termination Event (which Exchange Business Day shall in no event be earlier than the related settlement date for such Convertible Notes) as an Early Termination Date (and Dealer shall use its reasonable efforts to designate such Early Termination Date so that the related payment hereunder in respect of the Make-Whole Conversion Options will occur on (or as promptly as reasonably practicable after) the related settlement for the conversion of the relevant Convertible Notes) with respect to the portion of this Transaction corresponding to a number of Options (the “ Make-Whole Conversion Options ”) equal to the lesser of (A) the number of such Options specified in such Notice of Exercise minus the number of “Make-Whole Conversion Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Make-Whole Conversion Options.

(3) the per Share opening price as displayed under the heading “Op” on Bloomberg page AMAG <equity> (or any successor thereto) on the date on which Shares are delivered upon conversion to Holders of the Convertible Notes corresponding to such Make-Whole Conversion Options over (II) the aggregate principal amount of such Convertible Notes, as determined by the Calculation Agent in a commercially reasonable manner.

(i) Amendments to Equity Definitions .

Share Termination Alternative: If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable (the “ Share Termination Payment Date ”), in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.

Share Termination Delivery Property: A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price.

Each of Dealer and Counterparty represents and acknowledges to the other that upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero.

(w) Inversion Transaction . Counterparty shall not enter into or consummate any Inversion Transaction unless the successor Counterparty immediately following such Inversion Transaction repeats to Dealer immediately following such Inversion Transaction the representations and warranties set forth in Sections 8(a), 8(b), 8(c), 8(i) and 8(j) of this Confirmation (as if references therein to (i) “execute, deliver” were replaced with “assume”, (ii) “execution, delivery” and “execution and delivery” were replaced with “assumption” and (iii) “executed and delivered” were replaced with “assumed”). Notwithstanding anything to the contrary in this Confirmation if Counterparty enters into or consummates any Inversion Transaction pursuant to which Counterparty following such Inversion Transaction is organized under the laws of a jurisdiction other than the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, then such Inversion Transaction shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. If, at any time following the occurrence of any Inversion Transaction, Dealer reasonably determines in its good faith judgment that (x) such Inversion Transaction has had a material adverse effect on Dealer’s rights and obligations under the Transaction or (y) Dealer would incur an increased (as compared with circumstances existing on the Trade Date) amount of tax, duty, expense or fee (other than brokerage commissions and excluding (I) any de minimis increased amount of tax, duty, expense or fee and (II) any such increased amount that is incurred solely due to the deterioration of the creditworthiness of Dealer), to (1) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the economic risk of entering into and performing its obligations with respect to the Transaction, or (2) realize, recover or remit the proceeds of any such transaction(s) or asset(s) (each of the events described in clause (x) and clause (y) above, an “ Inversion Event ”), then, in either case, Dealer shall give prompt notice to Counterparty of such Inversion Event. Concurrently with delivering such notice, Dealer shall give notice to Counterparty of a commercially reasonable Price Adjustment that Dealer determines, in its good faith, commercially reasonable judgment, appropriate to account for the economic effect on the Transaction of such Inversion Event and provide Counterparty with supporting documentation for such Price Adjustment (unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, in which case Dealer shall so notify Counterparty). Unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, within two Scheduled Trading Days of receipt of such notice, Counterparty shall notify Dealer that it elects to (A) agree to amend the Transaction to take into account such Price Adjustment or (B) pay Dealer an amount determined by Dealer (and in respect of which Dealer has provided to Counterparty supporting documentation) that corresponds to such Price Adjustment (and, in each case, Counterparty shall be deemed to have repeated the representation set forth in Section 8(f) of this Confirmation as of the date of such election). If Counterparty fails to give such notice to Dealer of its election by the end of that second Scheduled Trading Day, or if Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, then such failure or such determination, as the case may be, shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (1) Counterparty shall be deemed to be the sole Affected Party, (2) the Transaction shall be the sole Affected Transaction and (3) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. For the avoidance of doubt, the parties hereto agree and acknowledge that the occurrence of an Inversion Event shall not preclude the occurrence of one or more additional, subsequent Inversion Events, it being understood and agreed that any Price Adjustment described in clause (A) above and/or any payment described in

clause (B) above shall be calculated without duplication in respect of any prior such Price Adjustment and/or payment.

(x) Counterparts . This Confirmation may be executed in several counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be

Dilution Adjustment Provisions:		Sections 14.04(a), 14.04(b), 14.04(c), 14.04(d) and 14.04(e) and Section 14.05 of the Supplemental Indenture.

If, in respect of any Merger Event to which the immediately preceding paragraph applies, the adjustments to be made in accordance with such paragraph would result in Counterparty being different from the issuer of the Shares, then with respect to such Merger Event, as a condition precedent to the adjustments contemplated in the immediately preceding paragraph, Dealer, the Issuer of the Affected Shares and the entity that will be the Issuer of the New Shares shall, prior to consummation of such Merger Event, have entered into such documentation containing agreements relating to “tacking” and “holding period” related considerations under U.S. securities law and credit exposure assumed by Dealer as the result Merger Event, as reasonably requested by Dealer that Dealer has determined, in its good faith, reasonable judgment, to be reasonably necessary or appropriate to allow Dealer to continue as a party to the Transaction, as adjusted under the immediately preceding paragraph, and to preserve its hedging or hedge unwind activities in connection with the Transaction in a manner compliant with applicable legal, and regulatory requirements, and if such conditions are not met or if the Calculation Agent determines that no adjustment under the immediately preceding paragraph will produce a commercially reasonable result, then the consequences set forth in Section 12.2(e)(ii) of the Equity Definitions shall apply to such Merger Event (as if Merger Event were as defined in Section 12.1(b) of the Equity Definitions).

Nationalization, Insolvency or Delisting: Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective

8. Representations and Warranties of Counterparty .

(f) Counterparty is not, on the date hereof, in possession of any material non-public information with respect to Counterparty or the Shares.

9. Other Provisions .

(e) Transfer or Assignment .

(B) Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended);

(E) An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment;

(G) Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

(ii) Dealer may transfer or assign all or any part of its rights or obligations under the Transaction (A) without Counterparty’s consent, to any third party (including, without limitation, any affiliate of Dealer) organized in the United States that has a rating at the time of such transfer or assignment for its long term, unsecured and unsubordinated indebtedness from either Standard and Poor’s Rating Group, Inc. or its successor (“ S&P ”) or Moody’s Investor Service, Inc. (“ Moody’s ”) (or, if both S&P and Moody’s ceases to rate such debt, by a substitute rating agency mutually agreed by Counterparty and Dealer) that is equal to or better than Dealer’s credit rating from such agency on the date hereof, or (B) with Counterparty’s consent, to any other third party (including, without limitation, any affiliate of Dealer) organized in the United States with a rating for its long term, unsecured and unsubordinated indebtedness from either S&P or Moody’s (or, if both S&P and Moody’s ceases to rate such debt, by a substitute rating agency mutually agreed by Counterparty and Dealer) that is equal to or better than Dealer’s credit rating from such agency at the time of the transfer; provided , in each case, that if such transfer or assignment would result in any tax withholding obligation of the transferee in respect of any tax and such withholding tax, without application of this sentence, would not be an Indemnifiable Tax, such tax shall be treated as an Indemnifiable Tax if such withholding tax obligation would not have applied to Dealer or such withholding tax would have been an Indemnifiable Tax of Dealer. Without limiting the foregoing, no transfer or assignment by Dealer shall be permitted hereunder that would result in the occurrence of an Event of Default, Potential Event of Default or Termination Event. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “ Excess Ownership Position ”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party in accordance with the two, immediately preceding sentences on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “ Terminated Portion ”), such that following such partial termination no Excess Ownership Position exists. Dealer shall notify Counterparty of an Excess Ownership Position with respect to which it intends to seek a transfer or assignment as soon as reasonably practicable after becoming aware of such Excess Ownership Position. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “ Section 16 Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “ Option Equity Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts

(iv) when specifying Staggered Settlement Dates pursuant to this Section 9(f), Dealer shall specify the fewest number of Staggered Settlement Dates as is practicable under the circumstances.

obligations hereunder shall relieve Dealer of such obligations to the extent of such performance. Any performance by Counterparty of its obligations (including notice obligations) through or by means of RBCCM’s agency for Dealer shall constitute good performance of Counterparty’s obligations hereunder to Dealer.

(h) Additional Termination Events .

(ii) Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty, within the applicable time period set forth under “Notice of Exercise” above, of any Notice of Exercise in respect of Options that relate to Convertible Notes as to which additional Shares would be added to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture in connection with a “Make-Whole Fundamental Change” (as defined in the Supplemental Indenture) shall constitute an Additional Termination Event as provided in this Section 9(h)(ii). Upon receipt of any such Notice of Exercise, Dealer shall designate an Exchange Business Day following such Additional Termination Event (which Exchange Business Day shall in no event be earlier than the related settlement date for such Convertible Notes) as an Early Termination Date (and Dealer shall use its reasonable efforts to designate such Early Termination Date so that the related payment hereunder in respect of the Make-Whole Conversion Options will occur on (or as promptly as reasonably practicable after) the related settlement for the conversion of the relevant Convertible Notes) with respect to the portion of this Transaction corresponding to a number of Options (the “ Make-Whole Conversion Options ”) equal to the lesser of (A) the number of such Options specified in such Notice of Exercise minus the number of “Make-Whole Conversion Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Make-Whole Conversion Options. Any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the number of Make-Whole Conversion Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were the sole Affected Transaction (and, for the avoidance of doubt, in determining the amount payable pursuant to Section 6 of the Agreement, the Calculation Agent shall not take into account any adjustments to the Option Entitlement that result from corresponding adjustments to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture); provided that the amount of cash deliverable in respect of such early termination by Dealer to Counterparty shall not be greater than the product of (x) the Applicable Percentage and (y) the excess of (I) (1) the number of Make-Whole Conversion Options, multiplied by (2) the Conversion Rate (after taking into account any applicable adjustments to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture), multiplied by (3) the per Share opening price as displayed under the heading “Op” on Bloomberg page AMAG <equity> (or any successor thereto) on the date on which Shares are delivered upon conversion to Holders of the Convertible Notes corresponding to such Make-Whole Conversion Options over (II) the aggregate principal amount of such Convertible Notes, as determined by the Calculation Agent in a commercially reasonable manner.

(i) Amendments to Equity Definitions .

fractional security based on the values used to calculate the Share Termination Unit Price.

Failure to Deliver: Applicable

Securities Act)), Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of equity securities of similar size; provided , however , that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) of this paragraph shall apply at the election of Counterparty or (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities of similar size, in form and substance reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any commercially reasonable adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement).

(r) Notice of Certain Other Events . Counterparty covenants and agrees that:

(the date of such notification, the “ Consideration Notification Date ”); provided that in no event shall the Consideration Notification Date be later than the date on which such Merger Event is consummated; and

therein to (i) “execute, deliver” were replaced with “assume”, (ii) “execution, delivery” and “execution and delivery” were replaced with “assumption” and (iii) “executed and delivered” were replaced with “assumed”). Notwithstanding anything to the contrary in this Confirmation if Counterparty enters into or consummates any Inversion Transaction pursuant to which Counterparty following such Inversion Transaction is organized under the laws of a jurisdiction other than the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, then such Inversion Transaction shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. If, at any time following the occurrence of any Inversion Transaction, Dealer reasonably determines in its good faith judgment that (x) such Inversion Transaction has had a material adverse effect on Dealer’s rights and obligations under the Transaction or (y) Dealer would incur an increased (as compared with circumstances existing on the Trade Date) amount of tax, duty, expense or fee (other than brokerage commissions and excluding (I) any de minimis increased amount of tax, duty, expense or fee and (II) any such increased amount that is incurred solely due to the deterioration of the creditworthiness of Dealer), to (1) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the economic risk of entering into and performing its obligations with respect to the Transaction, or (2) realize, recover or remit the proceeds of any such transaction(s) or asset(s) (each of the events described in clause (x) and clause (y) above, an “ Inversion Event ”), then, in either case, Dealer shall give prompt notice to Counterparty of such Inversion Event. Concurrently with delivering such notice, Dealer shall give notice to Counterparty of a commercially reasonable Price Adjustment that Dealer determines, in its good faith, commercially reasonable judgment, appropriate to account for the economic effect on the Transaction of such Inversion Event and provide Counterparty with supporting documentation for such Price Adjustment (unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, in which case Dealer shall so notify Counterparty). Unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, within two Scheduled Trading Days of receipt of such notice, Counterparty shall notify Dealer that it elects to (A) agree to amend the Transaction to take into account such Price Adjustment or (B) pay Dealer an amount determined by Dealer (and in respect of which Dealer has provided to Counterparty supporting documentation) that corresponds to such Price Adjustment (and, in each case, Counterparty shall be deemed to have repeated the representation set forth in Section 8(f) of this Confirmation as of the date of such election). If Counterparty fails to give such notice to Dealer of its election by the end of that second Scheduled Trading Day, or if Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, then such failure or such determination, as the case may be, shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (1) Counterparty shall be deemed to be the sole Affected Party, (2) the Transaction shall be the sole Affected Transaction and (3) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. For the avoidance of doubt, the parties hereto agree and acknowledge that the occurrence of an Inversion Event shall not preclude the occurrence of one or more additional, subsequent Inversion Events, it being understood and agreed that any Price Adjustment described in clause (A) above and/or any payment described in clause (B) above shall be calculated without duplication in respect of any prior such Price Adjustment and/or payment.

This Confirmation may be executed in several counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

We are very pleased to have executed the Transaction with you and we look forward to completing other transactions with you in the near future.

	Very truly yours,

Relevant Settlement Method:		In respect of any Option:

		(i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(a)(iv)(A) of the Supplemental Indenture (together with cash in lieu of fractional Shares) (such settlement method, “ Settlement in Shares ”), (B) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount less than USD 1,000 (such settlement method, “ Low Cash Combination Settlement ”) or (C) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Supplemental Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement;

Net Share Settlement:		If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “ Net Share Settlement Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that, for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date, in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the Settlement Date for such Option.

		Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

Combination Settlement:		If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option:

		(i) cash (the “ Combination Settlement Cash Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “ Daily Combination Settlement Cash Amount ”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

		(ii) Shares (the “ Combination Settlement Share Amount ”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day

		(the “ Daily Combination Settlement Share Amount ”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;

		provided that, for any Option exercised or deemed exercised hereunder on a Conversion Date occurring on or after the Free Convertibility Date, in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the Combination Settlement Share Amount for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.

		Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

Daily Option Value:		For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) the Relevant Price on such Valid Day less the Strike Price on such Valid Day; provided that if the calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.

Applicable Limit:		For any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder of the related Convertible Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note, in each case, as determined pursuant to the terms of the Supplemental Indenture, multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

Applicable Limit Price:		On any day, the opening price as displayed under the heading “Op” on Bloomberg page AMAG <equity> (or any successor thereto).

Valid Day:		A day on which (i) there is no Market Disruption Event and (ii) trading in the Shares generally occurs on the Exchange or, if the Shares are not then listed on the Exchange, on the principal other United States national or regional securities exchange on which the Shares are then listed or, if the Shares are not then listed on a United States national or regional securities exchange, on the principal other market on which the Shares are then listed or admitted for trading.

Relevant Price:		On any Valid Day, the per Share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page AMAG <equity> AQR (or its equivalent successor page if such page is not available) in respect of the period from the scheduled opening time of the Exchange to the Scheduled Closing Time of the Exchange on such Valid Day (or if such volume-weighted average price is unavailable or is manifestly inaccurate, the market value of one Share on such Valid Day, as determined by the Calculation Agent using, if practicable, a volume-weighted average method). The Relevant Price will be determined without regard to after hours trading or any other trading outside of the regular trading session trading hours.

For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be

		made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Supplemental Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section 14.04(c) of the Supplemental Indenture or the fourth sentence of Section 14.04(d) of the Supplemental Indenture).

Method of Adjustment:		Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any Potential Adjustment Event, the Calculation Agent shall make an adjustment to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction corresponding to the adjustment(s) under the Supplemental Indenture; provided that, notwithstanding the foregoing, if the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 14.05 of the Supplemental Indenture or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will determine the adjustment to be made to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner; provided, further , that, notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment was made to any Convertible Note under the Supplemental Indenture because the relevant Holder (as such term is defined in the Supplemental Indenture) was deemed to be a record owner of the underlying Shares on the related Conversion Date, then the Calculation Agent shall make an adjustment, as determined by it, to the terms hereof in order to account for such Potential Adjustment Event.

Dilution Adjustment Provisions:		Sections 14.04(a), 14.04(b), 14.04(c), 14.04(d) and 14.04(e) and Section 14.05 of the Supplemental Indenture.

Extraordinary Events applicable to the Transaction:

Merger Events:	Applicable; provided that notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in the definition of “Share Exchange Event” in Section 14.07 of the Supplemental Indenture.

Tender Offers:		Not Applicable

Consequence of Merger Events:		Notwithstanding Section 12.2 of the Equity Definitions, upon the occurrence of a Merger Event, the Calculation Agent shall make a corresponding adjustment, to the extent an analogous adjustment is made under the Supplemental Indenture, to any one or more of the nature of the Shares, Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction; provided , however , that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to any Excluded Provision.

		If, in respect of any Merger Event to which the immediately preceding paragraph applies, the adjustments to be made in accordance with such paragraph would result in Counterparty being different from the issuer of the Shares, then with respect to such Merger Event, as a condition precedent to the adjustments contemplated in the immediately preceding paragraph, Dealer, the Issuer of the Affected Shares and the entity that will be the Issuer of the New Shares shall, prior to consummation of such Merger Event, have entered into such documentation containing agreements relating to “tacking” and “holding period” related considerations under U.S. securities law and credit exposure assumed by Dealer as the result Merger Event, as reasonably requested by Dealer that Dealer has determined, in its good faith, reasonable judgment, to be reasonably necessary or appropriate to allow Dealer to continue as a party to the Transaction, as adjusted under the immediately preceding paragraph, and to preserve its hedging or hedge unwind activities in connection with the Transaction in a manner compliant with applicable legal, and regulatory requirements, and if such conditions are not met or if the Calculation Agent determines that no adjustment under the immediately preceding paragraph will produce a commercially reasonable result, then the consequences set forth in Section 12.2(e)(ii) of the Equity Definitions shall apply to such Merger Event (as if Merger Event were as defined in Section 12.1(b) of the Equity Definitions).

Nationalization, Insolvency or Delisting:		Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective

		successors), such exchange or quotation system shall thereafter be deemed to be the Exchange.

Additional Disruption Events:

Failure to Deliver:		Applicable

Hedging Disruption:		Applicable; provided that:

		(i) Section 12.9(a)(v) of the Equity Definitions is hereby amended by inserting the following three phrases at the end of such Section:

And, for the further avoidance of doubt, any such transactions or assets referred to in phrases (A) or (B) above must be available on commercially reasonable pricing terms. For purposes of the immediately preceding sentence, a de minimis increase in the cost of acquiring, establishing, re-establishing, substituting, maintaining, unwinding or disposing of any transaction(s) or asset(s) that the Hedging Party deems necessary to hedge the equity price risk of entering into and performing its obligations with respect to the relevant Transaction shall not give rise to a Hedging Disruption.”; and

		(ii) Section 12.9(b)(iii) of the Equity Definitions is hereby amended by inserting in the third line thereof, after the words “to terminate the Transaction”, the words “or a portion of the Transaction affected by such Hedging Disruption”.

8. Representations and Warranties of Counterparty .

(f) Counterparty is not, on the date hereof, in possession of any material non-public information with respect to Counterparty or the Shares.

9. Other Provisions .

(e) Transfer or Assignment .

(B) Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended);

(E) An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment;

(G) Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

(ii) Dealer may transfer or assign all or any part of its rights or obligations under the Transaction (A) without Counterparty’s consent, to any third party (including, without limitation, any affiliate of Dealer) organized in the United States that has a rating at the time of such transfer or assignment for its long term, unsecured and unsubordinated indebtedness from either Standard and Poor’s Rating Group, Inc. or its successor (“ S&P ”) or Moody’s Investor Service, Inc. (“ Moody’s ”) (or, if both S&P and Moody’s ceases to rate such debt, by a substitute rating agency mutually agreed by Counterparty and Dealer) that is equal to or better than Dealer’s credit rating from such agency on the date hereof, or (B) with Counterparty’s consent, to any other third party (including, without limitation, any affiliate of Dealer) organized in the United States with a rating for its long term, unsecured and unsubordinated indebtedness from either S&P or Moody’s (or, if both S&P and Moody’s ceases to rate such debt, by a substitute rating agency mutually agreed by Counterparty and Dealer) that is equal to or better than Dealer’s credit rating from such agency at the time of the transfer; provided , in each case, that if such transfer or assignment would result in any tax withholding obligation of the transferee in respect of any tax and such withholding tax, without application of this sentence, would not be an Indemnifiable Tax, such tax shall be treated as an Indemnifiable Tax if such withholding tax obligation would not have applied to Dealer or such withholding tax would have been an Indemnifiable Tax of Dealer. Without limiting the foregoing, no transfer or assignment by Dealer shall be permitted hereunder that would result in the occurrence of an Event of Default, Potential Event of Default or Termination Event. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “ Excess Ownership Position ”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party in accordance with the two, immediately preceding sentences on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “ Terminated Portion ”), such that following such partial termination no Excess Ownership Position exists. Dealer shall notify Counterparty of an Excess Ownership Position with respect to which it intends to seek a transfer or assignment as soon as reasonably practicable after becoming aware of such Excess Ownership Position. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “ Section 16 Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “ Option Equity Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts

(iv) when specifying Staggered Settlement Dates pursuant to this Section 9(f), Dealer shall specify the fewest number of Staggered Settlement Dates as is practicable under the circumstances.

to act as agent for Counterparty only to the extent required to satisfy the requirements of Rule 15a-6 under the Exchange Act in respect of the Transaction.

(h) Additional Termination Events .

(ii) Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty, within the applicable time period set forth under “Notice of Exercise” above, of any Notice of Exercise in respect of Options that relate to Convertible Notes as to which additional Shares would be added to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture in connection with a “Make-Whole Fundamental Change” (as defined in the Supplemental Indenture) shall constitute an Additional Termination Event as provided in this Section 9(h)(ii). Upon receipt of any such Notice of Exercise, Dealer shall designate an Exchange Business Day following such Additional Termination Event (which Exchange Business Day shall in no event be earlier than the related settlement date for such Convertible Notes) as an Early Termination Date (and Dealer shall use its reasonable efforts to designate such Early Termination Date so that the related payment hereunder in respect of the Make-Whole Conversion Options will occur on (or as promptly as reasonably practicable after) the related settlement for the conversion of the relevant Convertible Notes) with respect to the portion of this Transaction corresponding to a number of Options (the “ Make-Whole Conversion Options ”) equal to the lesser of (A) the number of such Options specified in such Notice of Exercise minus the number of “Make-Whole Conversion Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Make-Whole Conversion Options. Any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the number of Make-Whole Conversion Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were the sole Affected Transaction (and, for the avoidance of doubt, in determining the amount payable pursuant to Section 6 of the Agreement, the Calculation Agent shall not take into account any adjustments to the Option Entitlement that result from corresponding adjustments to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture); provided that the amount of cash deliverable in respect of such early termination by Dealer to Counterparty shall not be greater than the product of (x) the Applicable Percentage and (y) the excess of (I) (1) the number of Make-Whole Conversion Options, multiplied by (2) the Conversion Rate (after taking into account any applicable adjustments to the Conversion Rate pursuant to Section 14.03 of the Supplemental Indenture), multiplied by (3) the per Share opening price as displayed under the heading “Op” on Bloomberg page AMAG <equity> (or any successor thereto) on the date on which Shares are delivered upon conversion to Holders of the Convertible Notes corresponding to such Make-Whole Conversion Options over (II) the aggregate principal amount of such Convertible Notes, as determined by the Calculation Agent in a commercially reasonable manner.

(i) Amendments to Equity Definitions .

Share Termination Alternative:		If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable (the “ Share Termination Payment Date ”), in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.

Share Termination Delivery Property:		A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.

Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its good faith discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.

Share Termination Delivery Unit:		One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “ Exchange Property ”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.

Failure to Deliver:		Applicable

Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of equity securities of similar size; provided , however , that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) of this paragraph shall apply at the election of Counterparty or (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities of similar size, in form and substance reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any commercially reasonable adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement).

(r) Notice of Certain Other Events . Counterparty covenants and agrees that:

Share Termination Delivery Property:	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the relevant Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price (without giving effect to any discount pursuant to Section 9(k)(i)).

Notwithstanding anything to the contrary in this Confirmation if Company enters into or consummates any Inversion Transaction pursuant to which Company following such Inversion Transaction is organized under the laws of a jurisdiction other than the Islands of Bermuda, the Netherlands, Belgium, Switzerland, Luxembourg, the Republic of Ireland, Canada or the United Kingdom, then such Inversion Transaction shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Company shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. If, at any time following the occurrence of any Inversion Transaction, Dealer reasonably determines in its good faith judgment that (x) such Inversion Transaction has had a material adverse effect on Dealer’s rights and obligations under the Transaction or (y) Dealer would incur an increased (as compared with circumstances existing on the Trade Date) amount of tax, duty, expense or fee (other than brokerage commissions and excluding (I) any de minimis increased amount of tax, duty, expense or fee and (II) any such increased amount that is incurred solely due to the deterioration of the creditworthiness of Dealer), to (1) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the economic risk of entering into and performing its obligations with respect to the Transaction, or (2) realize, recover or remit the proceeds of any such transaction(s) or asset(s) (each of the events described in clause (x) and clause (y) above, an “ Inversion Event ”), then, in either case, Dealer shall give prompt notice to Company of such Inversion Event. Concurrently with delivering such notice, Dealer shall give notice to Company of a commercially reasonable Price Adjustment that Dealer determines, in its good faith, commercially reasonable judgment, appropriate to account for the economic effect on the Transaction of such Inversion Event and provide Company with supporting documentation for such Price Adjustment (unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, in which case Dealer shall so notify Company). Unless Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, within two Scheduled Trading Days of receipt of such notice, Company shall notify Dealer that it elects to (A) agree to amend the Transaction to take into account such Price Adjustment or (B) pay Dealer an amount determined by Dealer (and in respect of which Dealer has provided to Company supporting documentation) that corresponds to such Price Adjustment (and, in each case, Company shall be deemed to have repeated the representation set forth in Section 8(g) of this Confirmation as of the date of such election). If Company fails to give such notice to Dealer of its election by the end of that second Scheduled Trading Day, or if Dealer determines in its good faith, commercially reasonable judgment that no Price Adjustment will produce a commercially reasonably result, then such failure or such determination, as the case may be, shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (1) Company shall be deemed to be the sole Affected Party, (2) the Transaction shall be the sole Affected Transaction and (3) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. For the avoidance of doubt, the parties hereto agree and acknowledge that the occurrence of an Inversion Event shall not preclude the occurrence of one or more additional, subsequent Inversion Events, it being understood and agreed that any Price Adjustment described in clause (A) above and/or any payment described in clause (B) above shall be calculated without duplication in respect of any prior such Price Adjustment and/or payment.

(y) Counterparts . This Confirmation may be executed in several counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

(x) adding the word “or” immediately before subsection “(B)” and deleting the comma at the end of subsection (A); and

(j) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events .

Share Termination Alternative:	If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “ Share Termination Payment Date ”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, subject to Section 9(k)(i) below, in satisfaction, subject to Section 9(k)(ii) below, of the relevant Payment Obligation, in the manner reasonably requested by Dealer free of payment.

Share Termination Delivery Property:	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the relevant Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price (without giving effect to any discount pursuant to Section 9(k)(i)).

Share Termination Unit Price:	The value to Dealer of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its discretion by commercially reasonable means. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in Section 9(k)(i) below, the Share Termination Unit Price shall be determined by the discounted price applicable to such Share Termination Delivery Units. In the case of a Registration Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as set forth in Section 9(k)(ii) below, notwithstanding the foregoing, the Share Termination Unit Price shall be the Settlement Price on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable.

If such Nationalization, Insolvency or Merger Event involves a choice of Exchange Property to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.

Failure to Deliver:	Inapplicable

Other applicable provisions:	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11 and 9.12 (as modified above) of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

(i) If Company elects to settle the Transaction pursuant to this clause (i) (a “ Private Placement Settlement ”), then delivery of Restricted Shares by Company shall be effected in customary

(p) Maximum Share Delivery .

Company shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.

(e) Transfer or Assignment . Company may not transfer any of its rights or obligations under the Transaction without the prior written consent of Dealer. Dealer may, (i) without Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any affiliate of Dealer, and (ii) with Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any third party; provided , in each case, that (x) Company will not be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Company would have been required to pay to Dealer in the absence of such transfer or assignment, and (y) Dealer shall have caused the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Company. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Warrant Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “ Excess Ownership Position ”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Warrants to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “ Terminated Portion ”), such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a Terminated Portion, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Warrants equal to the number of Warrants underlying the Terminated Portion, (2) Company were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the Company shall be able to settle any corresponding obligation in cash or in Share Termination Delivery Units in its discretion in accordance with the provisions of Section 9(j).

The “ Warrant Equity Percentage ” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Warrants and the Warrant Entitlement and (2) the aggregate number of Shares underlying any other warrants purchased by Dealer from Company, and (B) the denominator of which is the number of Shares outstanding. The “ Share Amount ” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “ Dealer Person ”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Company that are, in each case, applicable to ownership of Shares (“ Applicable Restrictions ”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “ Applicable Share Limit ” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations (other than any Form 13F, Schedule 13D or Schedule 13G filing under the Exchange Act) or other requirements (including obtaining prior approval from any person or entity but excluding any such requirement in respect of which prior approval has been obtained) of a Dealer Person, or would result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding. Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Company, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Company only to the extent of any such performance.

(E) Section 12.9(b)(iv) of the Equity Definitions is hereby amended by:

(x) deleting (1) subsection (A) in its entirety, (2) the phrase “or (B)” following subsection (A) and (3) the phrase “in each case” in subsection (B); and

(y) replacing the phrase “neither the Non-Hedging Party nor the Lending Party lends Shares” with the phrase “such Lending Party does not lend Shares” in the penultimate sentence.

(F) Section 12.9(b)(v) of the Equity Definitions is hereby amended by:

(x) adding the word “or” immediately before subsection “(B)” and deleting the comma at the end of subsection (A); and

(j) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events .

Share Termination Alternative: If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “ Share Termination Payment Date ”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, subject to Section 9(k)(i) below, in satisfaction, subject to Section 9(k)(ii) below, of the relevant Payment Obligation, in the manner reasonably requested by Dealer free of payment.

Share Termination Delivery

Property: A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the relevant Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price (without giving effect to any discount pursuant to Section 9(k)(i)).

Share Termination Unit Price: The value to Dealer of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its discretion by commercially reasonable means. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in Section 9(k)(i) below, the Share Termination Unit Price shall be determined by the discounted price applicable to such Share Termination Delivery Units. In the case of a Registration Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as set forth in Section 9(k)(ii) below, notwithstanding the foregoing, the Share Termination Unit Price shall be the Settlement Price on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable.

The Calculation Agent shall notify Company of the Share Termination Unit Price at the time of notification of such Payment Obligation to Company or, if applicable, at the time the discounted price applicable to the relevant Share Termination Units is determined pursuant to Section 9(k)(i).

Share Termination Delivery Unit: One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “ Exchange Property ”), a unit consisting of the type and amount of Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event. If such Nationalization, Insolvency or Merger Event involves a choice of Exchange Property to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.

Failure to Deliver: Inapplicable

Other applicable provisions: If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11 and 9.12 (as modified above) of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.

Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery and after taking into account any Shares deliverable to Dealer under the Base Warrant Confirmation, (i) the Section 16 Percentage would exceed 7.5%, or (ii) the Share Amount would exceed the Applicable Share Limit. If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Company’s obligation to make such delivery shall not be extinguished and Company shall make such delivery as promptly as practicable after, but in no event later than one Business Day after, Dealer gives notice to Company that, after such delivery, (i) the Section 16 Percentage would not exceed 7.5%, and (ii) the Share Amount would not exceed the Applicable Share Limit.

(p) Maximum Share Delivery .
