Introduction .

KBR, Inc. (the “ Company ”) has completed its previously announced private offering of $350 million aggregate principal amount of its 2.50% convertible senior notes due 2023 (the “ Notes ”) to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “ Securities Act ”). The Company used a portion of the net proceeds from the sale of the Notes to repay a portion of the outstanding indebtedness under its Credit Agreement (as defined below). Accordingly, the Notes effectively lower the Company’s cash interest rate on its outstanding indebtedness, increase the Company’s fixed-to-floating debt ratio and restore the Company’s availability under the Credit Agreement.

In connection with the pricing of the Notes, the Company entered into the Convertible Note Hedge Transactions (as defined below), which are expected to generally reduce the potential dilution upon conversion of the Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted Notes, as the case may be. The Company also entered into the Warrant Transactions (as defined below), which could separately have a dilutive effect on the Company’s common stock to the extent that the market price per share of the Company’s common stock exceeds the strike price of the warrants, which is initially $40.02 per share and represents a 100% premium to the $20.01 per share closing price of the Company’s common stock on November 12, 2018.

The Company intends to settle the principal amount of the Notes in cash at maturity.

Item 1.01 Entry into a Material Definitive Agreement.

Purchase Agreement

On November 12, 2018, the Company entered into a Purchase Agreement (the “ Purchase Agreement ”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative of the several initial purchasers named in Schedule A to the Purchase Agreement (collectively, the “ Initial Purchasers ”), relating to the issuance and sale of the Notes.

The Purchase Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions under which the Company, on one hand, and the Initial Purchasers, on the other, have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

Affiliates of all of the Initial Purchasers are lenders under the Company’s credit agreement with Bank of America, N.A., as Administrative Agent, Swing Line Lender and a Letter of Credit Issuer, and the other lenders party thereto, dated April 25, 2018 (the “ Credit Agreement ”), to be repaid with a portion of the net proceeds from the sale of the Notes, and will receive a ratable portion of such portion of the net proceeds from the offering of the Notes. An affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated serves as Administrative Agent, Swing Line Lender and a Letter of Credit Issuer under the Credit Agreement.

A copy of the Purchase Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference. The foregoing summary description of the Purchase Agreement is qualified in its entirety by the terms of the Purchase Agreement.

Indenture

The Notes were issued pursuant to an Indenture, dated as of November 15, 2018 (the “ Indenture ”), between the Company and Citibank, N.A., as trustee. The Notes bear cash interest at a rate of 2.50% per year, payable semi-annually in arrears on May 1 and November 1 of each year, beginning on May 1, 2019. The Notes will mature on November 1, 2023, unless earlier repurchased or converted in accordance with their terms. The initial conversion rate for the Notes is 39.1961 shares of the Company’s common stock per $1,000 principal amount of Notes, which is

equivalent to an initial conversion price of approximately $25.51 per share of common stock, and is subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. The initial conversion price of the Notes represents a premium of approximately 27.5% to the $20.01 per share closing price of the Company’s common stock on November 12, 2018. Holders may convert all or any portion of their Notes at their option at any time prior to the close of business on the business day immediately preceding May 1, 2023 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2019 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, 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 ten 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 Company’s common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On or after May 1, 2023 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at its election, as described in the Indenture.

If the Company undergoes a fundamental change (as defined in the Indenture) prior to the maturity date, holders may require the Company to repurchase for cash all or any portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Indenture includes customary terms and covenants, including certain events of default after which the Notes may be due and payable immediately.

The Notes are senior unsecured obligations of the Company. The Notes rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes; rank equal in right of payment to the Company’s unsecured indebtedness that is not so subordinated; are effectively junior in right of payment to any of the Company’s senior, secured indebtedness to the extent of the value of the assets securing such indebtedness; and are structurally junior to all indebtedness and liabilities (including trade payables) of the Company’s subsidiaries.

The net proceeds from the sale of the Notes were approximately $341 million, after deducting the Initial Purchasers’ discounts and estimated offering expenses payable by the Company. The Company used approximately $200 million of the net proceeds to reduce its senior secured debt by repaying a portion of the outstanding indebtedness under its Credit Agreement, to maximize committed capital to fund ongoing investments. The Company used approximately $40 million of the net proceeds to pay the cost, before applicable future tax benefits, of the Convertible Note Hedge Transactions (as defined below), after such cost was partially offset by the proceeds to the Company from the Warrant Transactions (as defined below).

The foregoing description of the Indenture and the Notes is qualified in its entirety by reference to the Indenture (including the form of the Note), which is attached hereto as Exhibit 4.1 and incorporated herein by reference.

Convertible Note Hedge Transactions

In connection with the pricing of the Notes on November 12, 2018, the Company entered into privately negotiated convertible note hedge transactions (together, the “ Convertible Note Hedge Transactions ”) with each of Bank of

America, N.A., Citibank, N.A and BNP Paribas (together, the “ Option Counterparties ”). The Convertible Note Hedge Transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the Notes, the aggregate number of shares of the Company’s common stock underlying the Notes, and are expected generally to reduce or offset potential dilution to the Company’s common stock upon any conversion of notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes, as the case may be. On November 12, 2018, the Company also entered into separate warrant transactions (the “ Warrant Transactions ”) with each of the Option Counterparties, under which the Company sold to the Option Counterparties warrants relating to the same number of shares of the Company’s common stock. The Convertible Note Hedge Transactions are expected generally to reduce the potential dilution upon conversion of the Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted Notes, as the case may be, in the event that the market price per share of the Company’s common stock, as measured under the terms of the Convertible Note Hedge Transactions, is greater than the strike price of the Convertible Note Hedge Transactions, which initially corresponds to the conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes. If, however, the market price per share of the Company’s common stock, as measured under the terms of the Warrant Transactions, exceeds the strike price of the warrants, there would nevertheless be dilution to the extent that such market price exceeds the strike price of the warrants. The strike price of the Warrant Transactions will initially be $40.02 per share of the Company’s common stock and is subject to certain adjustments under the terms of the Warrant Transactions. The Convertible Note Hedge Transactions and the Warrant Transactions are separate transactions, in each case, entered into by the Company with the Option Counterparties, and are not part of the terms of the Notes and will not affect any holder’s rights under the Notes. Holders of the Notes will not have any rights with respect to the Convertible Note Hedge Transactions or the Warrant Transactions.

Affiliates of the Option Counterparties are lenders under the Credit Agreement, to be repaid with a portion of the net proceeds from the offering of the Notes, and will receive a portion of the net proceeds from this offering from the offering of the Notes applied to the Convertible Note Hedge Transactions and Warrant Transactions. An affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated serves as Administrative Agent, Swing Line Lender and a Letter of Credit Issuer under the Credit Agreement.

The foregoing description of the Convertible Notes Hedge Transactions and Warrant Transactions is qualified in its entirety by reference to the confirmations for the Convertible Notes Hedge Transactions and Warrant Transactions, which are attached as Exhibits 10.2, 10.3, 10.4, 10.5, 10.6 and 10.7 and incorporated herein by reference.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information set forth under Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

Item 3.02 Unregistered Sales of Equity Securities.

The information set forth under Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

The Company offered and sold the Notes to the Initial Purchasers in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act, and for resale by the Initial Purchasers to qualified institutional buyers pursuant to the exemption from registration provided by Rule 144A under the Securities Act. The Company relied on these exemptions from registration based in part on representations made by the Initial Purchasers. The offer and sale of the Notes and the shares of the Company’s common stock issuable upon conversion of the Notes, if any, have not been registered under the Securities Act, and the Notes and any such shares may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. The Company

expects any shares of common stock issued upon conversion of the Notes to be issued pursuant to the exemption provided by Section 3(a)(9) of the Securities Act. A maximum of 17,491,250 shares of common stock are initially issuable upon conversion of the Notes, based on the initial maximum conversion rate of 49.9750 shares of the Company’s common stock per $1,000 principal amount of Notes, which is subject to anti-dilution adjustments as set forth in the Indenture.

The Company entered into the Warrant Transactions with the Option Counterparties in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act. The Company relied on this exemption from registration based in part on representations made by the Option Counterparties. The Warrant Transactions and the shares of the Company’s common stock issuable upon exercise of the warrants comprising the Warrant Transactions, if any, have not been registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. A maximum of 27,437,270 shares of common stock are issuable upon exercise of the warrants issued in the Warrant Transactions.

Please see Exhibit 99.3 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on November 13, 2018 for a presentation related to the Company’s management of potential share dilution in connection with the Notes.

Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed the “ Note Registrar ” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with Section 4.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

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

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

No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer.

None of the Company, the Trustee, the Note Registrar or any co-Note 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 this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange.

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fourth paragraph from the end of Section 2.05(c) all Notes shall be represented by one or more Notes in global form (each, a “ Global Note ”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

(c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any Common Stock issued upon conversion of the Notes that is required to bear the legend set forth in Section 2.05(d), collectively, the “ Restricted Securities ”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the holder of each such Restricted Security, by such holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c) and Section 2.05(d), the term “ transfer ” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

Until the date (the “ Resale Restriction Termination Date ”) that is the later of (1) the date that is one year after the last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in Section 2.05(d), if applicable) shall bear a legend in substantially the following form (the “ Restrictive Legend ”) (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee):

THIS NOTE AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS NOTE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ SECURITIES ACT ”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

(1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

(2) AGREES FOR THE BENEFIT OF KBR, INC. (THE “ COMPANY ”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS NOTE OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been checked.

Any Note (or security issued in exchange or substitution therefor) (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restrictive Legend required by this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Restrictive Legend set forth above and affixed on any Note will be deemed, in accordance with the terms of the certificate representing such Note, to be removed therefrom upon the Company’s delivery to the Trustee of written notice to such effect, without further action by the Company, the Trustee, the Holder(s) thereof or any other Person; at such time, such Note will be deemed to be assigned an unrestricted CUSIP number as provided in the certificate representing such Note, it being understood that the Depositary of any Global Note may require a mandatory exchange or other process to cause such Global Note to be identified by an unrestricted CUSIP number in the facilities of such Depositary. Without limiting the generality of any other provision of this Indenture, the Trustee will be entitled to receive an instruction letter from the Company before taking any action with respect to effecting any such mandatory exchange or other process. In connection with any proposed transfer of a Note pursuant to an exemption from registration provided by Rule 144 or any other available exemption from the registration requirements of the Securities Act, the Company and the Trustee reserve the right to require the delivery of such legal opinions, certifications or other evidence as

may reasonably be required in order to determine that any such transfer is being made in compliance with the Securities Act and applicable state securities laws.

The Company shall be entitled to instruct the Custodian in writing to so surrender any Global Note as to which any of the conditions set forth in clause (i) through (iii) of the immediately preceding sentence have been satisfied, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the Restrictive Legend specified in this Section 2.05(c) and shall not be assigned (or deemed assigned) a restricted CUSIP number. The Company shall promptly notify the Trustee in writing upon the occurrence of the Resale Restriction Termination Date and promptly after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding paragraph.

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 Cede & Co.

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

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall

instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

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

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

(d) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Note shall bear a legend in substantially the following form (unless such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon conversion of a Note that has transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent for the Common Stock):

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ SECURITIES ACT ”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

(2) AGREES FOR THE BENEFIT OF KBR, INC. (THE “ COMPANY ”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE

THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE OF THE SERIES OF NOTES UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

Any such Common Stock (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.05(d).

(e) 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 immediately 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). 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 2.08.

(f) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any securities laws or restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note) 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.

(g) The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and beneficial owners. None of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any act or omission of the Depositary. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made only to, or upon the order of, the registered Holder(s) (which shall be the Depositary or its nominee in the case of a Global Note).

Section 2.06 . Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of a Company Order and of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the

Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender.

Section 2.07 . Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

Section 2.08 . 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 that the Company controls other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by it. Except for any Notes surrendered for registration of transfer or exchange, or as otherwise expressly permitted by any of the provisions of this Indenture, no Notes shall be authenticated in exchange for any Notes surrendered to the Trustee for cancellation. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall

deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order.

Section 2.09 . 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 2.10 . Additional Notes; Repurchases. The Company may, without the consent of, or notice to, the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue date, 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 Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 17.05, 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, its Subsidiaries or its affiliates or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08 and such Notes shall no longer be considered outstanding under this Indenture upon their repurchase.

ARTICLE 3
SATISFACTION AND DISCHARGE

Section 3.01 . Satisfaction and Discharge. This Indenture and the Company’s obligations under the Notes shall upon request of the Company contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture and the Company’s obligations under the Notes, when (a) (i) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or cash, shares of Common Stock or a combination thereof, as applicable, solely to satisfy the Company’s Conversion Obligation,

sufficient to pay all of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture and the Company’s obligations under the Notes have been complied with. Notwithstanding the satisfaction and discharge of this Indenture and the Company’s obligations under the Notes, the obligations of the Company to the Trustee under Section 7.06 shall survive.

ARTICLE 4
PARTICULAR COVENANTS OF THE COMPANY

Section 4.01 . Payment of Principal and Interest. 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 . Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City of New York, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“ Paying Agent ”) or for conversion (“ Conversion Agent ”) and where notices and demands to or upon the Company in respect of the Notes and this 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 office or agency. 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 in the Borough of Manhattan, The City of New York. For the avoidance of doubt, the Trustee shall not be considered an agent of the Company for service of process.

The Company may also from time to time designate as co-Note 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 Borough of Manhattan, The City of New York, 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, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office as the office or agency in the Borough of Manhattan, The City of New York, 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 to or upon the Company in respect of the Notes and this Indenture may be served.

Section 4.03 . Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 4.04 . Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause 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 4.04:

(i) that it will hold all sums held by it as such agent for the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes;

(ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and

(iii) 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.

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) 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) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

(d) Subject to applicable escheatment laws, any money and shares of Common Stock deposited with the Trustee 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 Officers’ 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 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.

(a) At any time the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issuable upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial owner of such Notes or such Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A, as such rule may be amended from time to time.

(b) The Company shall file with the Trustee, within 15 days after the same are required to be filed with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system.

(c) Delivery of the reports and documents described in Section 4.06 to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or 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 Officers’ Certificate).

(d) If, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace

periods thereunder and other than reports on Form 8-K), or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is continuing or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes. As used in this Section 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

The Restrictive Legend on the Notes shall be deemed removed pursuant to the terms of the Indenture as provided in Section 2.05(c), and, at such time, the Notes will, pursuant to, and subject to the provisions of, such Section, be deemed assigned an unrestricted CUSIP number. However, for the avoidance of doubt, for Notes that are not in certificated form, the Notes will continue to bear Additional Interest pursuant to this paragraph until such time as they are identified by an unrestricted CUSIP in the facilities of the Depositary or any successor depositary for the Notes, as a result of completion of the Depositary’s mandatory exchange process or otherwise.

(f) Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes.

(g) The Additional Interest that is payable in accordance with Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03.

(h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or Section 4.06(e), the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives at

the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment.

Section 4.07 . 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 this 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 4.08 . 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, 2018) an Officers’ Certificate 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 this Indenture and, if so, specifying each such failure and the nature thereof.

Section 6.02. 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 6.01(i) or Section 6.01(j) with respect to the Company or any of its Significant Subsidiaries), 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, 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 this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company or any of its Significant Subsidiaries 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, plus one percent) and amounts due to the Trustee pursuant to Section 7.06, 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 this 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 6.09, 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 this 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 6.03. Additional Interest . Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall 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 0.25% per annum of the principal amount of the Notes outstanding for each day during the 60-day period on which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e). If the Company so elects, 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 61st day after such Event of Default (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 61st day), the Notes shall be immediately subject to acceleration as provided in Section 6.02. The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in Section 4.06(b). In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 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 6.02.

In order to elect to pay Additional Interest as the sole remedy during the first 60 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 60-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

Section 6.04 . Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 6.01 shall have occurred, and be continuing, 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, plus one percent, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. 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 6.04, 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, disbursements and advances 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; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

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

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

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this 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 this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 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 6.05 . 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 (including its agents and counsel) under Section 7.06;

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, plus one percent, 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 plus one percent, 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 any 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 6.06 . 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 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, 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;

(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 such 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 6.09,

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 this Indenture to affect, disturb or prejudice the rights of any other Holder (it being understood that the Trustee shall not have an affirmative duty to ascertain whether or not any such direction is unduly prejudicial to 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 this 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 6.06, 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 this Indenture and any provision of any Note, each Holder shall have the right to receive payment or delivery, as the case may be, of (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 this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be.

Section 6.07 . 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 this 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 this 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.

Section 6.08 . Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.06, 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 this 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 6.06, 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 6.09 . 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 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 this 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 (it being understood that the Trustee shall not have an affirmative duty to ascertain whether or not any such direction is unduly prejudicial to any other Holder). The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 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 6.01, (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 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section 6.10 . Notice of Defaults.

The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee.

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section 7.07 . Officers’ Certificate as Evidence.

Section 7.08 . Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this

Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.09 . Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by delivering notice thereof to the Holders.

If no successor trustee shall have been so appointed and have accepted appointment within 60 days after the giving of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders and at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, subject to the provisions of Section 6.11, on behalf of himself or herself 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.

as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee.

Section 7.10 . Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06.

No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08.

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee hereunder to the Holders. If the Company fails to deliver such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be delivered at the expense of the Company.

Section 7.11 . Succession by Merger, Etc.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor

to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided , however , that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 7.12 . Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective.

Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action.

In the 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. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 9.02 or Section 9.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of Notes represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice.

Any supplemental indenture authorized by the provisions of this Section 10.01 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 10.02.

ARTICLE 11
CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

Section 11.01 . Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 11.02, 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 a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, 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 this Indenture; and

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

For purposes of this Section 11.01, 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 11.02 . Successor Corporation 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, 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 this 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 the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this 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 this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this 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 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 this 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 11.03 . 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 Officers’ 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, that all conditions precedent to such consolidation, merger, sale conveyance, transfer or lease have been complied with, and such Opinion of Counsel shall state that this Indenture, the Notes and such supplemental indenture, if any, are the legal, valid and binding obligations of the Successor Company, enforceable against it in accordance with their terms and subject to customary qualifications and exceptions.

ARTICLE 12
IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

Section 12.01 . Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or accrued and unpaid interest on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, 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 all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue 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 1, 2023, 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 1, 2023 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 39.1961 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 1, 2023, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any ten consecutive Trading Day period (the “ Measurement Period ”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock on each such Trading Day and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent (if not the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the Conversion Rate on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company so instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent and the Company fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion

Agent (if other than the Trustee). If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing.

(ii) If, prior to the close of business on the Business Day immediately preceding May 1, 2023, 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, 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 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 50 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, even if the Notes are not otherwise convertible at such time.

(iii) If (1) a transaction or event that constitutes (x) a Fundamental Change or (y) a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding May 1, 2023, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or (2) the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets that occurs prior to the close of business on the Business Day immediately preceding May 1, 2023, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, then, in each case, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the date that is 50 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the earlier of (x) the Business Day after the Company gives notice of such transaction and (y) the actual effective date of such transaction) until 35 Trading Days after the actual effective date of such transaction or event 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) (x) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 50 Scheduled Trading Days prior to the anticipated effective date of such transaction or (y) if the Company does not have knowledge of such transaction at least 50 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the date upon which the Company receives notice, or otherwise becomes aware, 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 1, 2023, 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, 2019 (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, and including, 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, 2019 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) if the Notes become convertible in accordance with this clause (iv).

Section 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 1, 2023 shall be settled using the same Settlement Method.

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

(iii) If, in respect of any Conversion Date (or the period described in the third immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “ Settlement Notice ”) of the relevant Settlement Method in respect

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

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

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

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive 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 40 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 for converting a beneficial interest in a Global Note and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and, if required, pay all transfer or similar taxes, if any, as set forth in Section 14.02(e) 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 second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the second 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 a converting Holder, the Company shall issue or cause to be issued, and deliver (if applicable) to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary, in satisfaction of the Company’s Conversion Obligation.

(d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the 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 such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(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 will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of 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; 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 in cash 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 be treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion.

(j) 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) (such period, the “ Make-Whole Fundamental Change Period ”).

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 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 for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “ Effective Date ”) and the price (the “ 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 Board of Directors 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 number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 14.04.

(e) The following table sets forth the number of Additional Shares of Common Stock 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	$20.01	$21.00	$22.00	$24.00	$25.51	$30.00	$35.00	$40.00	$60.00	$80.00	$100.00	$120.00

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

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower 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 $120.00 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), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $20.01 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), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 49.9750 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 (before giving effect to any such dividend, distribution, split or combination); 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 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, 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 of the Common Stock 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 the provisions set forth in Section 14.04(d) shall apply, and (iii) 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 at the close of business on the last Trading Day of the Valuation Period; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, and including, the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, and including, such Trading Day in determining the Conversion Rate as of such Trading Day.

For purposes of this Section 14.04(c) (and subject in all respect 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 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 any cash dividend or distribution is made to all or substantially all holders of the Common Stock, other than a regular, quarterly cash dividend that does not exceed $0.08 per share (the “ Initial Dividend Threshold ”), 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;

T = the Initial Dividend Threshold; provided that if the dividend or distribution is not a regular quarterly cash dividend, the Initial Dividend Threshold shall be deemed to be zero; and

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

The Initial Dividend Threshold shall be subject to adjustment in a manner inversely proportional to adjustments to the Conversion Rate; provided that no adjustment shall be made to the Initial Dividend Threshold for any adjustment to the Conversion Rate pursuant to this Section 14.04(d).

Any increase 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 it holds, 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 in effect on the Ex-Dividend Date for such cash dividend or distribution.

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of 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 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 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 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 (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date that such tender or exchange offer expires to, and including, the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the expiration date of such tender or exchange offer to, and including, such Trading Day in determining the Conversion Rate as of such Trading Day.

(f) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 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 listing standards 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 listing standards 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 deliver to the Holder of each Note, the Trustee and Conversion Agent (if other than the Trustee) a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

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

(v) 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.

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the adjusted Conversion Rate, (ii) the subsection of this Section 14.04 pursuant to which such adjustment has been made, showing in reasonable detail the facts upon which such adjustment is based and (iii) the date as of which such adjustment is effective (which certificate shall be conclusive evidence of the accuracy of such adjustment absent manifest error). Unless and until a Responsible Officer of the Trustee shall have received such Officers’

Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to each Holder. 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 this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including, without limitation, an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

Section 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 delivery of the maximum number of Additional Shares pursuant to Section 14.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable).

Section 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 subdivision or combination),

(ii) any consolidation, merger, combination or similar transaction 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 “ Merger Event ”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “ Reference Property ,” with each “ unit of Reference Property ” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes; provided , however , that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 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 Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be the weighted average of 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 Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger 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 by any Additional Shares pursuant to Section 14.03), multiplied by the price paid per share of Common Stock in such Merger Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second 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 Merger 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 corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be

executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the 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 Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be delivered to each Holder 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 Merger Event unless its terms are consistent with this Section 14.07. None of the foregoing provisions shall affect the right of a Holder 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 Merger Event.

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

(e) In connection with any Merger Event, the Initial Dividend Threshold shall be subject to adjustment as described in clause (i), clause (ii) or clause (iii) below, as the case may be.

(i) In the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed entirely of shares of common stock (the “ Merger Common Stock ”), the Initial Dividend Threshold at and after the effective time of such Merger Event will be equal to (x) the Initial Dividend Threshold immediately prior to the effective time of such Merger Event, divided by (y) the number of shares of Merger Common Stock that a holder of one share of Common Stock would receive in such Merger Event (such quotient rounded down to the nearest cent).

(ii) In the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed in part of shares of Merger Common Stock, the Initial Dividend Threshold at and after the effective time of such Merger Event will be equal to (x) the Initial Dividend Threshold immediately prior to the effective time of such Merger Event, multiplied by (y) the Merger Valuation Percentage for such Merger Event (such product rounded down to the nearest cent).

(iii) For the avoidance of doubt, in the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above and

excluding any dissenters’ appraisal rights) is composed entirely of consideration other than shares of common stock, the Initial Dividend Threshold at and after the effective time of such Merger Event will be equal to zero.

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 and charges with respect to the issue thereof.

(b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any 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. 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 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 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). Neither the Trustee nor any other agent acting under this Indenture (other than the Company, if acting in such capacity) shall have any obligation to make any calculation or to determine whether the Notes may be surrendered for conversion pursuant to this Indenture, or to notify the Company or the Depositary or any of the Holders if the Notes have become convertible pursuant to the terms of this Indenture.

Section 14.10 . Notice to Holders Prior to Certain Actions. In case of any:

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 14.04 or Section 14.11;

(b) Merger Event; or

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up.

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.

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 of the principal amount thereof properly surrendered and not validly withdrawn pursuant to Section 15.03 that is equal to $1,000 or a multiple of $1,000, on the date (the “ Fundamental Change Repurchase Date ”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “ Fundamental Change Repurchase Price ”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of 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 on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

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

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

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

(ii) the portion of the principal amount of Notes to be repurchased, which must be in minimum denominations of $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 this Indenture;

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

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 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 calendar 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. Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the

Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and

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

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

At the Company’s request, the Paying Agent 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.

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 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,

(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 will deposit with the 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 4.04, 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 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 Note Register; provided , however , that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Paying Agent 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 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 will cease to be outstanding, (ii) interest will 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 will terminate (other than the right to receive the Fundamental Change Repurchase Price and, if applicable, accrued and unpaid interest).

(c) Upon surrender of a 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 will, 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

[FORM OF REVERSE OF NOTE]

KBR, INC.
2.50% Convertible Senior Note due 2023

This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.50% Convertible Senior Notes due 2023 (the “ Notes ”), limited to the aggregate principal amount of $350,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Initial Purchasers pursuant to the exercise of their over-allotment option to purchase additional Notes as set forth in the Purchase Agreement) all issued or to be issued under and pursuant to an Indenture dated as of November 15, 2018 (the “ Indenture ”), between the Company and Citibank, N.A. (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 will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The 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.

Each Holder shall have the right 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, this Note at the place, at the respective times, at the rate and in the lawful money or shares of Common Stock, as the case may be, herein prescribed.

A- 6

The Notes are issuable in registered form without coupons in minimum 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.

Ladies and Gentlemen:

KBR, Inc., a Delaware corporation (the “Company”), confirms its agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) and each of the other Initial Purchasers named in Schedule A hereto (collectively, the “Initial Purchasers,” which term shall also include any initial purchaser substituted as hereinafter provided in Section 10 hereof), for whom Merrill Lynch is acting as representative (in such capacity, the “Representative”), with respect to (i) the sale by the Company and the purchase by the Initial Purchasers, acting severally and not jointly, of the respective principal amounts set forth in said Schedule A of $350,000,000 aggregate principal amount of the Company’s 2.50% Convertible Senior Notes due 2023 (the “Initial Securities”) and (ii) the grant by the Company to the Initial Purchasers, acting severally and not jointly, of the option to purchase all or any part of an additional $52,500,000 aggregate principal amount of its 2.50% Convertible Senior Notes due 2023 (the “Option Securities” and, together with the Initial Securities, the “Securities”) solely to cover overallotments. The Securities are to be issued pursuant to an indenture to be dated as of November 15, 2018 (the “Indenture”) between the Company and Citibank, N.A., as trustee (the “Trustee”). The Securities will be convertible into cash, shares of common stock of the Company, par value $0.001 per share (“Common Stock”), or a combination of cash and shares of Common Stock, at the option of the Company, on the terms, and subject to the conditions, set forth in the Indenture.

In connection with the offering of the Initial Securities, the Company is separately entering into convertible note hedge transactions and warrant transactions with certain of the Initial Purchasers or their respective affiliates (the “Call Spread Counterparties”), in each case pursuant to convertible note hedge confirmations (the “Base Bond Hedge Confirmations”) and warrant confirmations (the “Base Warrant Confirmations” and, the Base Warrant Confirmations together with the Base Bond Hedge Confirmations, the “Base Call Spread Confirmations”), each to be dated the date hereof, and in connection with any exercise by the Initial Purchasers of their option to purchase any Option Securities, the Company and the

Call Spread Counterparties may enter into additional convertible note hedge transactions and additional warrant transactions pursuant to additional convertible note hedge confirmations (the “Additional Bond Hedge Confirmations”) and additional warrant confirmations (the “Additional Warrant Confirmations” and, the Additional Warrant Confirmations together with the Additional Bond Hedge Confirmations, the “Additional Call Spread Confirmations”), each to be dated the date on which the Initial Purchasers exercise their option to purchase such Option Securities. We refer to the Base Call Spread Confirmations and the Additional Call Spread Confirmations collectively herein as the “Call Spread Confirmations.”

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (“Subsequent Purchasers”) at any time after this Agreement has been executed and delivered. The Securities are to be offered and sold through the Initial Purchasers without being registered under the Securities Act of 1933, as amended (the “1933 Act”), in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the Indenture, investors that acquire Securities may only resell or otherwise transfer such Securities if such Securities are hereafter registered under the 1933 Act or if an exemption from the registration requirements of the 1933 Act is available (including the exemption afforded by Rule 144A (“Rule 144A”) of the rules and regulations promulgated under the 1933 Act (the “1933 Act Regulations”) by the Securities and Exchange Commission (the “Commission”)).

The Company has prepared and delivered to each Initial Purchaser copies of a preliminary offering memorandum dated November 12, 2018 prior to the Applicable Time (as defined below) (the “Preliminary Offering Memorandum”) and has prepared and will deliver to each Initial Purchaser, on the date hereof or the next succeeding day, copies of a final offering memorandum dated November 12, 2018 (the “Final Offering Memorandum”), each for use by such Initial Purchaser in connection with its solicitation of purchases of, or offering of, the Securities. “Offering Memorandum” means, with respect to any date or time referred to in this Agreement, the most recent offering memorandum (whether the Preliminary Offering Memorandum or the Final Offering Memorandum, or any amendment or supplement to either such document), including exhibits thereto and any documents incorporated therein by reference, which has been prepared and delivered by the Company to the Initial Purchasers, in the case of the Preliminary Offering Memorandum prior to the Applicable Time, in connection with their solicitation of purchases of, or offering of, the Securities. The Company will prepare a final term sheet reflecting the final terms of the Securities, in the form set forth in Schedule B hereto (the “Final Term Sheet”), and will deliver such Final Term Sheet to the Initial Purchasers prior to the Applicable Time in connection with their solicitation of purchases of, or offering of, the Securities. The Company agrees that, unless it obtains the prior written consent of the Representatives, it will not make any offer relating to the Securities by any written materials other than the Offering Memorandum and the Issuer Written Information. “Issuer Written Information” means (i) any writing intended for general distribution to investors as evidenced by its being specified in Schedule C hereto, including the Final Term Sheet, and (ii) any “road show” that is a “written communication” within the meaning of the 1933 Act. “General Disclosure Package” means the Preliminary Offering Memorandum and any Issuer Written Information specified on Schedule C hereto and issued at or prior to 10:30 P.M., New York City time, on November 12, 2018 or such other time as agreed by the Company and Merrill Lynch (such date and time, the “Applicable Time”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Offering Memorandum (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which are incorporated by reference in the Offering Memorandum; and all references in this Agreement to amendments or supplements to the Offering Memorandum shall be deemed to mean and

include the filing of any document under the Securities Exchange Act of 1934 (the “1934 Act”) which is incorporated by reference in the Offering Memorandum.

SECTION 1. Representations and Warranties .

(a) Representations and Warranties by the Company . The Company represents and warrants to each Initial Purchaser as of the date hereof, the Applicable Time, the Closing Time (as defined below) and any Date of Delivery (as defined below), and agrees with each Initial Purchaser, as follows:

(i) General Disclosure Package; Rule 144A Eligibility . The Company hereby confirms that it has authorized the use of the General Disclosure Package, including the Preliminary Offering Memorandum and the Final Term Sheet, and the Final Offering Memorandum in connection with the offer and sale of the Securities by the Initial Purchasers. The Securities are eligible for resale pursuant to Rule 144A and will not be, at the Closing Time, of the same class as securities listed on a national securities exchange registered under Section 6 of the 1934 Act, or quoted in a U.S. automated interdealer quotation system.

(ii) No Registration Required; No General Solicitation . Subject to compliance by the Initial Purchasers with the representations and warranties of the Initial Purchasers and the procedures set forth in Section 6 hereof, it is not necessary in connection with the offer, sale and delivery of the offered Securities to the Initial Purchasers and to each Subsequent Purchaser in the manner contemplated by this Agreement, the General Disclosure Package and the Final Offering Memorandum to register the Securities under the 1933 Act or to qualify the Indenture under the Trust Indenture Act of 1939, as amended (the “1939 Act”).

Merrill Lynch, individually and not as representative of the Initial Purchasers, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Initial Purchaser whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Initial Purchaser from its obligations hereunder.

SECTION 3. Covenants of the Company . The Company covenants with each Initial Purchaser as follows:

(a) Delivery of Offering Memorandum . The Company has delivered to each Initial Purchaser, without charge, as many copies of the Preliminary Offering Memorandum (as amended or supplemented) thereto and documents incorporated by reference therein as such Initial Purchaser reasonably requested, and the Company hereby consents to the use of such copies. The Company will furnish to each Initial Purchaser, without charge, such number of copies of the Final Offering Memorandum thereto and documents incorporated by reference therein as such Initial Purchaser may reasonably request.

(b) Notice and Effect of Material Events . If at any time prior to the completion of resales of the Securities by the Initial Purchasers, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Initial Purchasers or for the Company, to amend or supplement the General Disclosure Package or the Final Offering Memorandum in order that the General Disclosure Package or the Final Offering Memorandum, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a Subsequent Purchaser, the Company will promptly (A) give the Representative notice of such event and (B) prepare any amendment or supplement as may be necessary to correct such statement or omission and, a reasonable amount of time prior to any proposed use or distribution, furnish the Representative with copies of any such amendment or supplement; provided that the Company shall not use or distribute any such amendment or supplement to which the Representative or counsel for the Initial Purchasers shall object. The Company will furnish to the Initial Purchasers such number of copies of such amendment or supplement as the Initial Purchasers may reasonably request.

(c) Reporting Requirements . Until the completion of resales of the Securities by the Initial Purchasers, the Company will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations. The Company will give the Representative notice of its intention to make any such filing from the Applicable Time to the Closing Time and will furnish the Representative with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representative or counsel for the Initial Purchasers shall reasonably object.

(d) Blue Sky Qualifications . The Company will use its commercially reasonable efforts, in cooperation with the Initial Purchasers, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representative may designate and to maintain such qualifications in effect so long as required to complete the distribution of the Securities; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(e) Use of Proceeds . The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the General Disclosure Package and the Final Offering Memorandum under “Use of Proceeds.”

(f) DTCC . The Company will cooperate with the Initial Purchasers and use its commercially reasonable efforts to permit the offered Securities to be eligible for clearance and settlement through the facilities of The Depository Trust & Clearing Corporation (“DTCC”).

(g) Reservation; Listing . The Company will use its commercially reasonable efforts to reserve and keep available at all times, free of preemptive or other similar rights, a number of shares of Common Stock equal to the Maximum Number of Underlying Securities and the Warrant Securities. The Company will use its commercially reasonable efforts to effect and maintain the listing of the Maximum Number of Underlying Securities and the Warrant Securities on the New York Stock Exchange.

(h) Restriction on Sale of Securities . During a period of 90 days from the date of the Final Offering Memorandum (the “Lock-Up Period”), the Company will not, without the prior written consent of Merrill Lynch, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file or confidentially submit any registration statement under the 1933 Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise. The foregoing sentence shall not apply to (A) the Securities to be sold hereunder and any shares of Common Stock issued upon conversion thereof, (B) any shares of Common Stock issued by the Company upon the settlement, vesting or exercise of an option, stock appreciation right, restricted stock unit, restricted stock award, performance share award or warrant or the conversion of a security outstanding on the date hereof and referred to in the General Disclosure Package and the Final Offering Memorandum, (C) any shares of Common Stock issued or options to purchase Common Stock or other equity-based awards granted pursuant to existing employee benefit plans or equity incentive plans of the Company referred to in the General Disclosure Package and the Final Offering Memorandum, (D) any shares of Common Stock issued pursuant to any non-employee director stock plan, deferred compensation plan, employee stock purchase plan or dividend reinvestment plan referred to in the General Disclosure Package and the Final

Offering Memorandum, (E) any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock issued in connection with acquisitions, joint ventures and similar types of arrangements of up to 5% of outstanding Common Stock in aggregate at the time of this Agreement, as long as the recipients of such securities also agree not to sell or transfer those securities without the prior written consent of Merrill Lynch during the Lock-Up Period, (F) the establishment of a trading plan pursuant to Rule 10b5-1 under the 1934 Act, provided that no public announcement or filing is voluntarily made or required regarding such plan during the Lock-Up Period, (G) the entry into the Warrant Confirmations or (H) any Common Stock issued upon exercise and settlement or termination of the warrant transactions evidenced by the Base Warrant Confirmations and any Additional Warrant Confirmations .

SECTION 4. Payment of Expenses .

(a) Expenses . The Company will pay or cause to be paid all expenses incident to the performance of their obligations under this Agreement, including (i) preparation, issuance and delivery of the Securities to the Initial Purchasers and the Common Stock issuable upon conversion thereof and any charges of DTCC in connection therewith, (ii) the fees and disbursements of the Company’s counsel, accountants and other advisors, (iii) the qualification of the Securities under securities laws in accordance with the provisions of Section 3(d) hereof, including filing fees and the reasonable fees and disbursements of a single counsel for the Initial Purchasers in connection therewith and in connection with the preparation of the Blue Sky Survey and any supplement thereto (provided that the Company’s obligation to pay such fees and expenses shall not exceed $5,000), (iv) the preparation, printing and delivery to the Initial Purchasers of copies of each Preliminary Offering Memorandum, any Issuer Written Information, the Final Term Sheet and the Final Offering Memorandum and any amendments or supplements thereto and any costs associated with electronic delivery of any of the foregoing by the Initial Purchasers to investors, (v) all fees and expenses of the Trustee and any expenses of any transfer agent or registrar for the Securities or the Common Stock issuable upon conversion of the Securities, (vi) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the Securities, including without limitation, expenses associated with the production of road show slides and graphics, and fees and expenses of any consultants engaged in connection with the road show presentations, and (vii) the fees and expenses incurred in connection with the listing of the Common Stock issuable upon conversion of the Securities and the exercise of the warrant transactions evidenced by the Base Warrant Confirmations and any Additional Warrant Confirmations on the New York Stock Exchange. It is understood, however, that, except as provided in this Section 4(a) and Section 4(b), the Initial Purchasers will pay all of their own costs and expenses, including the fees of their counsel and any advertising expenses connected with any offers they may make.

(b) Termination of Agreement . If this Agreement is terminated by the Representative in accordance with the provisions of Section 5 or Section 10(a)(i) or (iii) hereof, the Company shall reimburse the non-defaulting Initial Purchasers for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Initial Purchasers.

SECTION 6. Subsequent Offers and Resales of the Securities .

(a) Offer and Sale Procedures . Each of the Initial Purchasers and the Company hereby establish and agree to observe the following procedures in connection with the offer and sale of the Securities:

(i) Offers and Sales . Offers and sales of the Securities shall be made to such persons and in such manner as is contemplated by the Offering Memorandum. Each Initial Purchaser severally agrees that it will not offer, sell or deliver any of the Securities in any jurisdiction outside the United States except under circumstances that will result in compliance with the applicable laws thereof, and that it will take at its own expense whatever action is required to permit its purchase and resale of the Securities in such jurisdictions. The Company has not entered into any contractual arrangement, other than this Agreement, with respect to the distribution of the Securities or the Common Stock issuable upon conversion of the Securities and the Company will not enter into any such arrangement except as contemplated thereby.

(ii) No General Solicitation . No general solicitation or general advertising (within the meaning of Rule 502(c) under the 1933 Act Regulations) will be used in the United States in connection with the offering or sale of the Securities.

(iii) Legends . Each of the Securities will bear, to the extent applicable, the legend contained in “Notice to Investors” in the General Disclosure Package and the Final Offering Memorandum for the time period and upon the other terms stated therein.

(iv) Minimum Principal Amount . No sale of the Securities to any one Subsequent Purchaser will be for less than U.S. $1,000 principal amount and no Security will be issued in a smaller principal amount. If the Subsequent Purchaser is a non-bank fiduciary acting on behalf of others, each person for whom it is acting must purchase at least U.S. $1,000 principal amount of the Securities.

(b) Covenants of the Company . The Company covenants with each Initial Purchaser as follows:

(i) Integration . The Company agrees that it will not and will cause its Affiliates not to, directly or indirectly, solicit any offer to buy, sell or make any offer or sale of, or otherwise negotiate in respect of, securities of the Company of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the 1933 Act Regulations, such offer or sale would render invalid (for the purpose of (i) the sale of the offered Securities by the Company to the Initial Purchasers, (ii) the resale of the offered Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the offered Securities by such Subsequent Purchasers to others) the exemption from the registration requirements of the 1933 Act provided by Section 4(2) thereof or by Rule 144A thereunder or otherwise.

(ii) Rule 144A Information . The Company agrees that, in order to render the offered Securities eligible for resale pursuant to Rule 144A, while any of the offered Securities remain outstanding, it will make available, upon request, to any holder of offered Securities or prospective purchasers of Securities the information specified in Rule 144A(d)(4), unless the Company furnishes information to the Commission pursuant to Section 13 or 15(d) of the 1934 Act.

(iii) Restriction on Repurchases . Until the expiration of one year after the original issuance of the offered Securities, the Company will not, and will cause its Affiliates not to, resell any offered Securities which are “restricted securities” (as such term is defined under Rule 144(a)(3)), whether as beneficial owner or otherwise (except as agent acting as a securities broker on behalf of and for the account of customers in the ordinary course of business in unsolicited broker’s transactions).

(c) Representations, Warranties and Agreements of the Initial Purchasers . Each Initial Purchaser severally and not jointly represents and warrants to, and agrees with, the Company that it is a Qualified Institutional Buyer and an “accredited investor” within the meaning of Rule 501(a) under the 1933 Act Regulations. Each Initial Purchaser understands that the offered Securities have not been and will not be registered under the 1933 Act and may not be offered or sold within the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the 1933 Act. Each Initial Purchaser severally represents and agrees that it has not offered or sold, and will not offer or sell, any offered Securities constituting part of its allotment within the United States except in accordance with Rule 144A or another applicable exemption from the registration requirements of the 1933 Act. Accordingly, neither it nor any person acting on its behalf has made or will make offers or sales of the Securities in the United States by means of any form of general solicitation or general advertising (within the meaning of Regulation D) in the United States. Each Initial Purchaser will take reasonable steps to inform, and cause each of its affiliates (as such term is defined in Rule 501(b) under the 1933 Act Regulations (each, an “Affiliate”)) to take reasonable steps to inform, persons acquiring Securities from such Initial Purchaser or Affiliate, as the case may be, in the United States that the Securities (A) have not been and will not be registered under the 1933 Act, (B) are being sold to them without registration under the 1933 Act in reliance on Rule 144A or in accordance with another exemption from registration under the 1933 Act, as the case may be, and (C) may not be offered, sold or otherwise transferred except (1) to the Company, (2) outside the United States in accordance with Regulation S or (3) inside the United States in accordance with (x) Rule 144A to a person whom the seller reasonably believes is a Qualified Institutional Buyer that is purchasing such Securities for its own account or for the account of a Qualified Institutional Buyer to whom notice is given that the offer, sale or transfer is being made in reliance on Rule 144A or (y) pursuant to another available exemption from registration under the 1933 Act.

SECTION 7. Indemnification .

(a) Indemnification of Initial Purchasers . The Company agrees to indemnify and hold harmless each Initial Purchaser, its Affiliates, its selling agents and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact included in any Preliminary Offering Memorandum, the Final Offering Memorandum, the information contained in the Final Term Sheet, road show presentation materials or any Issuer Written Information in connection with the offer or sale of the Securities (or any amendment or

supplement to the foregoing) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in any Preliminary Offering Memorandum, the Final Offering Memorandum or the information contained in the Final Term Sheet (or any amendment or supplement to the foregoing) in reliance upon and in conformity with the Initial Purchaser Information.

(b) Indemnification of Company, Directors and Officers . Each Initial Purchaser severally agrees to indemnify and hold harmless the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in any Preliminary Offering Memorandum, the Final Offering Memorandum or the information contained in the Final Term Sheet (or any amendment or supplement to the foregoing) in reliance upon and in conformity with the Initial Purchaser Information.

(c) Actions against Parties; Notification . Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Company; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for

fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse . If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 8. Contribution . If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Initial Purchasers, on the other hand, bear to the aggregate initial offering price of the Securities as set forth on the cover of the Final Offering Memorandum.

The relative fault of the Company, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate

amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and distributed to the public were offered to the public exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Initial Purchaser’s Affiliates and selling agents shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, each officer of the Company, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the aggregate principal amount of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 9. Representations, Warranties and Agreements to Survive . All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Initial Purchaser or its Affiliates or selling agents, any person controlling any Initial Purchaser, its officers or directors or any person controlling the Company and (ii) delivery of and payment for the Securities.

SECTION 10. Termination of Agreement .

(a) Termination . The Representative may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, in the judgment of the Representative, since the time of execution of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Final Offering Memorandum, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or (iv) if trading generally on the NYSE MKT or the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a

material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (vi) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities . If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 7, 8, 9, 14, 15, 16 and 17 shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Initial Purchasers . If one or more of the Initial Purchasers shall fail at the Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Initial Purchasers, or any other initial purchasers, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Initial Purchasers, or

(ii) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased on such date, the Company shall have the right, within 48 hours thereafter, to make arrangements for any other the Initial Purchasers to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon the terms herein set forth. In the event such arrangements are not made within 48 hours after such default, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Initial Purchasers to purchase, and the Company to sell, the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Initial Purchaser.

No action taken pursuant to this Section shall relieve any defaulting Initial Purchaser from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Initial Purchasers to purchase and the Company to sell the relevant Option Securities, as the case may be, either the (i) Representative or (ii) the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the General Disclosure Package or the Final Offering Memorandum or in any other documents or arrangements.

Exhibit A-1

FORM OF OPINION OF COMPANY’S COUNSEL
TO BE DELIVERED PURSUANT TO SECTION 5(a)(i)

(i) The Company is validly existing as a corporation in good standing under the laws of the State of Delaware, has the corporate power and authority to own its property and to conduct its business as described in the General Disclosure Package and the Final Offering Memorandum and to enter into and perform its obligations under the Purchase Agreement, the Securities, the Indenture, the Call Spread Confirmations and the documents entered into by the Company in connection therewith (collectively, the “Transaction Documents”), and is duly qualified to transact business and is in good standing in each other jurisdiction where such qualification and status is required, except to the extent that the failure to be so qualified or be in good standing would not have a Material Adverse Effect.

(ii) The authorized capital stock of the Company conforms as to legal matters to the description thereof contained in the General Disclosure Package and the Final Offering Memorandum.

(iii) [ ](1) shares of Common Stock issuable upon conversion of the Securities have been duly authorized and reserved for issuance upon such conversion by all necessary corporate action, all outstanding shares of Common Stock have been duly authorized and are validly issued, fully paid and non-assessable and the Common Stock issuable upon conversion of the Securities will be, when issued in accordance with the terms of the Indenture, validly issued, fully paid and non-assessable and will not be subject to the preemptive or other similar rights of any securityholder of the Company arising under the Delaware General Corporation Law or the Amended and Restate Certificate of Incorporation of the Company or its bylaws, and no holder of such shares will be subject to personal liability by reason of being such a holder.

(iv) The Purchase Agreement has been duly authorized, executed and delivered by the Company.

(v) The Indenture has been duly authorized, executed and delivered by the Company and (assuming the due authorization, execution and delivery thereof by the Trustee) constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally or by general equitable principles (regardless of whether enforcement is considered in a proceeding in equity or at law).

(vi) The Securities are in the form contemplated by the Indenture, have been duly authorized, executed, issued and delivered by the Company and, assuming that the Securities have been duly authenticated by the Trustee in the manner required by the Indenture, the Securities constitute valid and binding obligations of the Company, enforceable against the

(1) To be the maximum number of shares of Common Stock issuable upon conversion of the Securities (including the maximum number of additional shares of Common Stock by which the conversion rate may be increased upon conversion in connection with a make-whole fundamental change and assuming (x) a single holder of Securities converted all of the Securities, (y) the Company elects physical settlement of such conversion and (z) the Initial Purchasers exercise their option to purchase the Option Securities in full).

A-1- 1

Company in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally or by general equitable principles (regardless of whether enforcement is considered in a proceeding in equity or at law), and will be entitled to the benefits of the Indenture.

(vii) The Call Spread Confirmations and the transaction documents entered into by the Company in connection therewith have been duly authorized, executed and delivered by the Company and constitute valid and binding agreements of the Company, enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally or by general equitable principles (regardless of whether enforcement is considered in a proceeding in equity or at law).

(viii) The execution and delivery by the Company of, and the performance by the Company of its obligations under, each of the Transaction Documents, and the consummation of the transactions contemplated therein and in the General Disclosure Package and the Final Offering Memorandum under the caption “Use of Proceeds”, will not contravene any provision of (A) any United States federal or New York State statute or the Delaware General Corporation Law which, in our opinion, based on our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents (“ United States Applicable Laws ”), except that we do not express any opinion with respect to state securities laws, (B) the certificate of incorporation or bylaws of the Company, (C) assuming the Company will meet the conditions set forth in Section 7.02(m) of the [Credit Agreement], as stated in an Officer’s Certificate (as defined in the Credit Agreement), any agreement listed on Exhibit A hereto (except as would not have a Material Adverse Effect), or (D) any judgment, order or decree of any United States federal or New York or Delaware State governmental body, agency or court having jurisdiction over the Company or any subsidiary of the Company and known to us;

(ix) Based upon our review of the United States Applicable Laws, no consent, approval, authorization or order of, or qualification with, any United States federal or New York or Delaware State governmental body or agency is required for the performance by the Company of its obligations under the Transaction Documents, except that we express no opinion regarding federal or state securities or Blue Sky laws.

(x) The statements relating to legal matters, documents or proceedings included in the General Disclosure Package and the Final Offering Memorandum under the captions “Certain United States Federal Income Tax Considerations,” “Description of Notes,” and “Description of Capital Stock” fairly summarize in all material respects such legal matters, documents or proceedings.

(xi) The Company is not, and after giving effect to the offering and sale of the Securities or the Call Spread Confirmations and the application of the proceeds thereof as described in the General Disclosure Package and the Final Offering Memorandum will not be, required to register as an “investment company” under the 1940 Act.

(xii) Assuming the accuracy of the representations and warranties of the Company and the Initial Purchasers in the Purchase Agreement and compliance with the agreements of the Company and the Initial Purchasers in the Purchase Agreement, it is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers and to each subsequent

A-1- 2

purchaser under the circumstances contemplated by the Purchase Agreement, the General Disclosure Package and the Final Offering Memorandum, as of its date, to register the Securities under the 1933 Act or to qualify the Indenture under the Trust Indenture Act of 1939, as amended, and the rules and regulations of the Commission promulgated thereunder; except we express no opinion regarding any resales of the Securities by any person other than the Initial Purchasers.

As indicated above, we examined various documents and participated in conferences with representatives of the Company and its accountants and with representatives of the Initial Purchasers and their counsel at which times the contents of the General Disclosure Package and the Final Offering Memorandum and related matters were discussed. However, except as specifically noted in our opinion in paragraph (x) above, we are not passing upon and assume no responsibility for the accuracy, completeness or fairness of the statements contained in the General Disclosure Package or the Final Offering Memorandum or making any representation that we have independently verified or checked the accuracy, completeness or fairness of such statements. Also, we are expressing no view as to the financial statements or schedules or other financial or statistical information included in or omitted from the General Disclosure Package and the Final Offering Memorandum. Subject to the foregoing, we advise you that no facts have come to our attention that caused us to believe that (i) the General Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (ii) the Final Offering Memorandum, as of its date or at the Closing Time, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinion, such counsel may rely as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).

Exhibit A-2

[FORM OF OPINION OF COMPANY’S GENERAL COUNSEL
TO BE DELIVERED PURSUANT TO SECTION 5(a)(ii)]

To the best of my knowledge, there is not pending or threatened any action, suit, proceeding, inquiry or investigation, to which the Company or any subsidiary is a party, or to which the property of the Company or any subsidiary is subject, before or brought by any court or governmental agency or body, domestic or foreign, which would reasonably be expected to result in a Material Adverse Effect, or which would reasonably be expected to materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in the Purchase Agreement or the performance by the Company of its obligations thereunder.

Dear Sirs:

The undersigned, a stockholder and an officer and/or director of KBR, Inc., a Delaware corporation (the “Company”), understands that Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) proposes to enter into a Purchase Agreement (the “Purchase Agreement”) with the Company providing for the offering of $350,000,000 aggregate principal amount of the Company’s 2.50% Convertible Senior Notes due 2023 (the “Securities”). In recognition of the benefit that such an offering will confer upon the undersigned as a stockholder and an officer and/or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each initial purchaser to be named in the Purchase Agreement that, during the period beginning on the date hereof and ending on the date that is 90 days from the date of the Purchase Agreement (the “Lock-up Period”), the undersigned will not, without the prior written consent of Merrill Lynch, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), or any securities convertible into or exercisable or exchangeable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (collectively, the “Lock-Up Securities”), or exercise any right with respect to the registration of any of the Lock-up Securities, or file, cause to be filed or cause to be confidentially submitted any registration statement in connection therewith, under the Securities Act of 1933, as amended, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise.

Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer the Lock-Up Securities without the prior written consent of Merrill Lynch, provided that (1) Merrill

B- 1

Lynch receives a signed lock-up agreement for the balance of the lockup period from each donee, trustee, distributee, or transferee, as the case may be, (2) any such transfer shall not involve a disposition for value, (3) such transfers are not required to be reported with the Securities and Exchange Commission (the “SEC”) on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers:

(i) as a bona fide gift or gifts; or

(ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin); or

(iii) as a distribution to limited partners or stockholders of the undersigned; or

(iv) by testate succession or intestate succession; or

(v) to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned.

Furthermore, the undersigned may sell shares of Common Stock of the Company purchased by the undersigned on the open market following the Public Offering if and only if (i) such sales are not required to be reported in any public report or filing with the Securities and Exchange Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales.

Furthermore, the restrictions set forth in this letter agreement shall not apply to:

(i) transfers to a bona fide third party pursuant to the consummation of a merger, consolidation or other similar transaction, approved by the board of directors of the Company, the result of which is that any “person” (as defined in Section 13(d)(3) of the Exchange Act), or group of persons, other than the Company, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of a majority of the total voting power of the common stock of the Company (each, a “Change of Control”), or (b) the entry into any lock-up, voting or similar agreement in connection with a Change of Control, pursuant to which the undersigned may agree to transfer, sell, tender or otherwise dispose of Lock-Up Securities in connection with such Change of Control, or vote any Lock-Up Securities in favor of any such Change of Control, and the satisfaction of such obligations thereunder, provided that, in either case, if such Change in Control is not consummated, the undersigned’s Lock-Up Securities shall remain subject to the restrictions contained herein;

(ii) the conversion or exercise of stock options or other equity securities convertible into or exercisable for Common Stock granted pursuant to the Company’s equity incentive plans that are outstanding as of the date of the Purchase Agreement and described in the General Disclosure Package and the Final Offering Memorandum (including the documents incorporated by reference therein) and which options or other securities would expire within the Lock-Up Period; provided that the restrictions set forth in this letter agreement shall apply to any of the undersigned’s shares of Common Stock or any security convertible into or exercisable for Common Stock issued upon such conversion or exercise except as otherwise provided herein;

B- 2

(iii) transfers of Lock-Up Securities to the Company (a) for the purpose of satisfying any tax or other governmental withholding obligation with respect to Lock-Up Securities issued upon the vesting or exercise of stock options or other equity securities convertible into or exercisable for Common Stock or (b) in connection with the “cashless exercise” of an option exercised pursuant to clause (ii) hereunder; provided that, to the extent such transaction requires a filing under Section 16 of the Exchange Act, such transfers are reported with the SEC on the applicable form under the transaction code “F;” and provided further, that any shares of Common Stock received by the undersigned upon any such exercise and not transferred to the Company will be subject to the restrictions of this letter agreement; or

(iv) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act (a “10b5-1 Plan”) for the transfer of shares of Common Stock, provided that such 10b5-1 Plan does not provide for the transfer of Common Stock during the Lock-Up Period and no public announcement or filing under the Exchange Act regarding the establishment of such 10b5-1 Plan shall be required of or voluntarily made by or on behalf of the undersigned during the Lock-Up Period;

provided, that (A) in the case of clauses (ii) and (iii) above, any public filing or report made with the SEC or otherwise shall state the reason for such transfer, and (B) in no case shall the undersigned or the Company voluntarily effect any public filing or report regarding such transfers.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions.

		(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 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.

		commercially reasonable manner as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by a counterparty establishing and maintaining a commercially reasonable hedge position in connection with its hedging activities as a result of such event or condition not having been publicly announced prior to the beginning of such period; and

		(iii) if any Potential Adjustment Event is declared and (a) the event or condition giving rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned, (b) the “Conversion Rate” (as defined in the Indenture) is otherwise not adjusted at the time or in the manner contemplated by the relevant Dilution Adjustment Provision based on such declaration or (c) the “Conversion Rate” (as defined in the Indenture) is adjusted as a result of such Potential Adjustment Event and subsequently re-adjusted (each of clauses (a), (b) and (c), a “ Potential Adjustment Event Change ”) then, in each case, the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by a counterparty establishing and maintaining a commercially reasonable hedge position in connection with its hedging activities as a result of such Potential Adjustment Event Change.

controlling persons (each, an “ Indemnified Person ”) from and against any and all losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. 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 Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding.

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.

(e) Transfer or Assignment .

(i) Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to all, but not less than all, of the Options hereunder (such Options, the “ Transfer Options ”); provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to the following conditions:

(A) With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 9(b) or any obligations under Section 9(m) or 9(r) of this Confirmation;

(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);

(C) Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty, as are requested and reasonably satisfactory to Dealer;

(D) Dealer will not, as a result of such transfer and assignment, 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 Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment;

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

(F) Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

(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, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction (A) to any affiliate of Dealer (1) that has a long-term issuer rating that is equal to or better than Dealer’s credit rating at the time of such transfer or assignment, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions provided, in each case, Counterparty will not, as a result of such transfer and assignment, 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 Counterparty would have been required to pay to Dealer in the absence of such transfer and assignment or (B) to any other third party with a long-term issuer rating equal to or better than the lesser of (1) the credit rating of Dealer at the time of the transfer and (2) A- by Standard and Poor’s Rating Group, Inc. or its successor (“ S&P ”), or A3 by Moody’s Investor Service, Inc. (“ Moody’s ”) or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer; provided that (a) Counterparty will not, as a result of such transfer and assignment, 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 Counterparty would have been required to pay to Dealer in the absence of such transfer and assignment, (b) Dealer shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Counterparty to permit Counterparty to determine that results described in clause (a) will not occur upon or after such transfer and assignment and (c) an Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment; provided

further, that Dealer shall provide written notice to Counterparty following any such Transfer. 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 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 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 any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. 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 or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could 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.

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; and

(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.

(g) Dividends . If at any time during the period from and including the Effective Date, to but excluding the Expiration Date, (i) an ex-dividend date for a regular quarterly cash dividend occurs with respect to the Shares (an “ Ex-Dividend Date ”), and that dividend is less than the Regular Dividend on a per Share basis or (ii) if no Ex-Dividend Date for a regular quarterly cash dividend occurs with respect to the Shares in any quarterly dividend period of Counterparty, then the Calculation Agent will make a corresponding adjustment to any one or more of the Strike Price, Number of Options, Option Entitlement and/or any other variable relevant to the exercise, settlement or payment for the Transaction to preserve the fair value of the Options to Dealer after taking into account such dividend or lack thereof. “ Regular Dividend ” shall mean USD 0.08 per Share per quarter. Upon any adjustment to the Initial Dividend Threshold (as defined in the Indenture) for the Convertible Notes pursuant to the Indenture, the Calculation Agent will make a corresponding adjustment to the Regular Dividend for 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 under the terms of the Convertible Notes as set forth in Section 6.01 of the 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.

conditions), or any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes to amend (other than, in each case, any amendment or supplement (x) pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum or (y) pursuant to Section 14.07 of the Indenture), in each case, without the consent of Dealer.

(iii) Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty, within the applicable time period set forth opposite “Notice of Exercise” in Section 2, 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 (as defined in the Indenture) pursuant to Section 14.03 of the Indenture in connection with a “Make-Whole Fundamental Change” (as defined in the Indenture) shall constitute an Additional Termination Event as provided in this Section 9(h)(iii). 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 with respect to the portion of the 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 (the “ Make-Whole Unwind Payment ”) 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 the 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 (as defined in the Indenture) pursuant to Section 14.03 of the Indenture); provided that the amount of cash payable 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 (as defined in the Indenture, and after taking into account any applicable adjustments to the Conversion Rate pursuant to Section 14.03 of the Indenture), multiplied by (3) a market price per Share determined by the Calculation Agent in a commercially reasonable manner 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 .

(i) Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) inserting “(1)” immediately following the word “means” in the first line thereof and (2) inserting immediately prior to the semi-colon at the end of subsection (B) thereof the following words: “or (2) 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”.

For the avoidance of doubt, in the event of bankruptcy or liquidation of Counterparty or Dealer, no party shall have the right to set off any obligation that it may have to the other parties under the Transaction against any obligation such other parties may have to it, whether arising under the Agreement, this Confirmation or any other agreement between the parties hereto, by operation of 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 all holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer 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, 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) Counterparty remakes the representation set forth in Section 8(f) as of the date of such election and (c) Dealer agrees, in its commercially reasonable 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, 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 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, if commercially reasonable, 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.

		(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 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.

		(ii) in connection with any Potential Adjustment Event as a result of an event or condition set forth in Section 14.04(b) of the Indenture or Section 14.04(c) of the Indenture where, in either case, the period for determining “Y” (as such term is used in Section 14.04(b) of the Indenture)

		or “SP 0 ” (as such term is used in Section 14.04(c) of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such Potential Adjustment Event, then the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by a counterparty establishing and maintaining a commercially reasonable hedge position in connection with its hedging activities as a result of such event or condition not having been publicly announced prior to the beginning of such period; and

		(iii) if any Potential Adjustment Event is declared and (a) the event or condition giving rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned, (b) the “Conversion Rate” (as defined in the Indenture) is otherwise not adjusted at the time or in the manner contemplated by the relevant Dilution Adjustment Provision based on such declaration or (c) the “Conversion Rate” (as defined in the Indenture) is adjusted as a result of such Potential Adjustment Event and subsequently re-adjusted (each of clauses (a), (b) and (c), a “ Potential Adjustment Event Change ”) then, in each case, the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by a counterparty establishing and maintaining a commercially reasonable hedge position in connection with its hedging activities as a result of such Potential Adjustment Event Change.

9. Other Provisions .

(b) Repurchase Notices . Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “ Repurchase Notice ”) on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than 129.3 million (in the case of the first such notice) or (ii) thereafter more than 9.8 million less than the number of Shares included in the immediately preceding Repurchase Notice. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “ Indemnified Person ”) from and against any and all losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. 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 Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. 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. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

(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.

transfer or assignment, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions provided, in each case, Counterparty will not, as a result of such transfer and assignment, 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 Counterparty would have been required to pay to Dealer in the absence of such transfer and assignment or (B) to any other third party with a long-term issuer rating equal to or better than the lesser of (1) the credit rating of Dealer at the time of the transfer and (2) A- by Standard and Poor’s Rating Group, Inc. or its successor (“ S&P ”), or A3 by Moody’s Investor Service, Inc. (“ Moody’s ”) or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer; provided that (a) Counterparty will not, as a result of such transfer and assignment, 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 Counterparty would have been required to pay to Dealer in the absence of such transfer and assignment, (b) Dealer shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Counterparty to permit Counterparty to determine that results described in clause (a) will not occur upon or after such transfer and assignment and (c) an Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment; provided further, that Dealer shall provide written notice to Counterparty following any such Transfer. 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 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 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 any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. 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 or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could 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.

(f) Staggered Settlement . If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s 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:

(h) Additional Termination Events .

(ii) Notwithstanding anything to the contrary in this Confirmation, the occurrence of an Amendment Event 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. “ Amendment Event ” means that Counterparty amends, modifies, supplements, waives or obtains a waiver in respect of any term of the Indenture or the Convertible Notes governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, any term relating to conversion of the Convertible Notes (including changes to the conversion rate, conversion rate adjustment provisions, conversion settlement dates or conversion conditions), or any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes to amend (other than, in each case, any amendment or supplement (x) pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum or (y) pursuant to Section 14.07 of the Indenture), in each case, without the consent of Dealer.

Conversion Options, multiplied by (2) the Conversion Rate (as defined in the Indenture, and after taking into account any applicable adjustments to the Conversion Rate pursuant to Section 14.03 of the Indenture), multiplied by (3) a market price per Share determined by the Calculation Agent in a commercially reasonable manner 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 .

(iii) Section 12.9(b)(vi) of the Equity Definitions is hereby amended by (1) adding the word “or” immediately before subsection “(B)”, (2) deleting the comma at the end of subsection (A), (3) deleting subsection (C) in its entirety, (4) deleting the word “or” immediately preceding subsection (C) and (5) replacing the words “either party” in the last sentence of such Section with “Dealer”.

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, 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 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, if commercially reasonable, 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 Share Termination Alternative is applicable to the Transaction.

(m) Registration . Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, the Shares (“ Hedge Shares ”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, use its best efforts to make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering; 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) or clause (iii) of this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, Counterparty shall use its best efforts to enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance satisfactory to Dealer (in which case, the Calculation Agent shall make any 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), or (iii) purchase the Hedge Shares from Dealer at the then-current market price on such Exchange Business Days, and in the amounts and at such time(s), requested by Dealer.

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. For the avoidance of doubt, any performance by Dealer of its obligations to Counterparty hereunder solely to BNPPSC shall not relieve Dealer of such obligations.

		(ii) Shares (the “ Combination Settlement Share Amount ”) equal to the sum, for each Valid Day

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 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 Indenture or the fifth sentence of Section 14.04(d) of the Indenture).

		Notwithstanding the foregoing and “Consequences of Merger Events / Tender Offers” below:

		(i) 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 Indenture, Section 14.07(a) of the Indenture or any supplemental indenture entered into thereunder 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 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 Indenture because the relevant Holder (as such term is defined in the 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 in a commercially reasonable manner, to the terms hereof in order to account for such Potential Adjustment Event;

		(ii) in connection with any Potential Adjustment Event as a result of an event or condition set forth in Section 14.04(b) of the Indenture or Section 14.04(c) of the Indenture where, in either case, the period for determining “Y” (as such term is used in Section 14.04(b) of the Indenture)

		or “SP 0 ” (as such term is used in Section 14.04(c) of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such Potential Adjustment Event, then the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by a counterparty establishing and maintaining a commercially reasonable hedge position in connection with its hedging activities as a result of such event or condition not having been publicly announced prior to the beginning of such period; and

		(iii) if any Potential Adjustment Event is declared and (a) the event or condition giving rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned, (b) the “Conversion Rate” (as defined in the Indenture) is otherwise not adjusted at the time or in the manner contemplated by the relevant Dilution Adjustment Provision based on such declaration or (c) the “Conversion Rate” (as defined in the Indenture) is adjusted as a result of such Potential Adjustment Event and subsequently re-adjusted (each of clauses (a), (b) and (c), a “ Potential Adjustment Event Change ”) then, in each case, the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by a counterparty establishing and maintaining a commercially reasonable hedge position in connection with its hedging activities as a result of such Potential Adjustment Event Change.

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.

breaches, defaults or Repayment Events (as defined in the Purchase Agreement) or liens, charges or encumbrances that would not, singly or in the aggregate, result in a Material Adverse Effect (as defined in the Purchase Agreement), nor will such action result in any violation of (a) the provisions of the charter, by-laws or similar organizational document of Counterparty or any of its subsidiaries or (b) any law, statute, rule, regulation, judgment, order, writ or decree of any Governmental Entity (as defined in the Purchase Agreement), except, in the case of clause (b) above, for such violations that would not, singly or in the aggregate, result in a Material Adverse Effect (as defined in the Purchase Agreement).

(f) Each of it and its affiliates 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.

Section 2(d)(i)(4) of the Agreement greater than an amount that Counterparty would have been required to pay to Dealer in the absence of such transfer and assignment, (b) Dealer shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Counterparty to permit Counterparty to determine that results described in clause (a) will not occur upon or after such transfer and assignment and (c) an Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment; provided further, that Dealer shall provide written notice to Counterparty following any such Transfer. 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 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 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 any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. 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 or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could 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.

(h) Additional Termination Events .

(i) Amendments to Equity Definitions .

(i) Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) inserting “(1)” immediately following the word “means” in the first line thereof and (2) inserting

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, 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 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, if commercially reasonable, 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 Share Termination Alternative is applicable to the Transaction.

other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

(ii) Dealer agrees to deliver to Counterparty a valid, accurate and complete U.S. Internal Revenue Service Form W-9 (or any successor form) and any required attachments thereto (A) upon execution of this Confirmation, (B) promptly upon reasonable demand by Counterparty and (C) promptly upon learning that any Form W-9 (or any successor thereto) previously provided by Dealer has become obsolete, invalid or incorrect.

For the avoidance of doubt, a FATCA Withholding Tax is a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement.

(y) 871(m) . The parties agree that the definitions and provisions contained in the 2015 Section 871(m) Protocol, as published by ISDA, are incorporated into and apply to the Agreement solely for purposes of this Confirmation as if set forth in full herein.

Settlement Method:		Net Share Settlement.

Net Share Settlement:		On the relevant Settlement Date, Company shall deliver to Dealer a number of Shares equal to the Share Delivery

		Quantity for such Settlement Date to the account specified herein free of payment through the Clearance System, and Dealer shall be treated as the holder of record of such Shares at the time of delivery of such Shares or, if earlier, at 5:00 p.m. (New York City time) on such Settlement Date, and Company shall pay to Dealer cash in lieu of any fractional Share based on the Settlement Price on the relevant Valuation Date.

Share Delivery Quantity:		For any Settlement Date, a number of Shares, as calculated by the Calculation Agent, equal to the Net Share Settlement Amount for such Settlement Date divided by the Settlement Price on the Valuation Date for such Settlement Date.

Net Share Settlement Amount:		For any Settlement Date, an amount equal to the product of (i) the number of Warrants exercised or deemed exercised on the relevant Exercise Date , (ii) the Strike Price Differential for the relevant Valuation Date and (iii) the Warrant Entitlement.

Notwithstanding the foregoing, if (i) any Expiration Date is a Disrupted Day and (ii) the Calculation Agent determines that such Expiration Date shall be an Expiration Date for fewer than the Daily Number of Warrants, as described above, then the Settlement Price for the relevant Valuation Date shall be the volume-weighted average price per Share on such Valuation Date on the Exchange, as determined by the Calculation Agent based on such sources as it deems appropriate using a volume-weighted methodology, for the portion of such Valuation Date for which the Calculation Agent determines there is no Market Disruption Event.

limitations arising from Company’s status as issuer of the Shares under applicable securities laws.

(c) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any Governmental Entity (as defined in the Purchase Agreement) is necessary or required for the performance by Company of its obligations hereunder or the consummation of the Transaction contemplated by this Confirmation or for the due execution, delivery and performance of this Confirmation, except such as have been already obtained and excluding any filing, authorization, approval, consent, license, order, registration, qualification or decree the failure of which to obtain or make would not have a Material Adverse Effect (as defined in the Purchase Agreement).

(d) A number of Shares equal to the Maximum Number of Shares (as defined below) (the “ Warrant Shares ”) have been reserved for issuance by all required corporate action of Company. The Warrant Shares have been duly authorized and, when delivered against payment therefor (which may include Net Share Settlement in lieu of cash) and otherwise as contemplated by the terms of the Warrants following the exercise of the Warrants in accordance with the terms and conditions of the Warrants, will be validly issued, fully-paid and non-assessable, and the issuance of the Warrant Shares will not be subject to any preemptive or similar rights.

(i) Company (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million.

9. Other Provisions .

(a) Opinions . 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) through (d) of this Confirmation, which shall be deemed delivered to Dealer hereunder if delivered to Dealer under the Purchase Agreement. 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.

(b) Repurchase Notices . Company shall, on any day on which Company effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “ Repurchase Notice ”) on such day if following such repurchase, the number of outstanding Shares on such day, subject to any adjustments provided herein, is (i) less than 129.3 million (in the case of the first such notice) or (ii) thereafter more than 9.8 million less than the number of Shares included in the immediately preceding Repurchase Notice. Company agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “ Indemnified Person ”) from and against any and all losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person actually may become subject to, 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, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person, such Indemnified Person shall promptly notify Company in writing, and Company, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Company may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Company agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Company shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. 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 Company under such paragraph, 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 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. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

(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 a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Company shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.

(d) No Manipulation . Company is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.

(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, without Company’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any third party; provided , (A) Company will not, as a result of such transfer and assignment, 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 and assignment, (B) Dealer shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Company to permit Company to determine that results described in clause (A) will not occur upon or after such transfer and assignment, (C) an Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment and (D) Dealer shall provide written notice to Company following any such Transfer. 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 provisions of Section 9(i) shall apply to any amount that is payable by Company to Dealer pursuant to this sentence as if Company 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 any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. 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 or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could 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 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, (i) an ex-dividend date for a cash dividend occurs with respect to the Shares (an “ Ex-Dividend Date ”), and that dividend differs from the Regular Dividend on a per Share basis or (ii) if no Ex-Dividend Date for a cash dividend occurs with respect to the Shares in any quarterly dividend period of Company, 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 or lack thereof. “ Regular Dividend ” shall mean for any calendar quarter, USD 0.08 for the first regular cash dividend or distribution on the Shares for which the Ex-Dividend Date falls within such calendar quarter, and zero for any other dividend or distribution on the Shares for which the Ex-Dividend Date falls within the same calendar quarter.

(y) (1) deleting subsection (C) in its entirety, (2) deleting the word “or” immediately preceding subsection (C) and (3) deleting the final sentence in its entirety and replacing it with the sentence “The Hedging Party will determine the Cancellation Amount payable by one party to the other.”

(ii) Notwithstanding anything to the contrary in this Confirmation, upon the occurrence of one of the following events, with respect to the Transaction, (1) Dealer shall have the right to designate such event an Additional Termination Event and designate an Early Termination Date pursuant to Section 6(b) of the Agreement, (2) Company shall be deemed the sole Affected Party with respect to such Additional Termination Event and (3) the Transaction, or, at the election of Dealer in its reasonable discretion, any portion of the Transaction, shall be deemed the sole Affected Transaction; provided that if Dealer so designates an Early Termination Date with respect to a portion of the Transaction, (a) a payment shall be made pursuant to Section 6 of the Agreement as if 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 included in the terminated portion of the Transaction, and (b) for the avoidance of doubt, the Transaction shall remain in full force and effect except that the Number of Warrants shall be reduced by the number of Warrants included in such terminated portion:

(A) A “person” or “group” within the meaning of Section 13(d) of the Exchange Act, other than Company, its wholly owned subsidiaries and its and their employee benefit plans, has become the direct or indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of the Shares representing more than 50% of the voting power of the Shares.

(B) Consummation of (I) any recapitalization, reclassification or change of the Shares (other than changes resulting from a subdivision or combination) as a result of which the Shares would be converted into, or exchanged for, stock, other securities, other property or assets, (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 wholly owned subsidiaries. Notwithstanding the foregoing, any transaction or transactions set forth in clause (A) above or 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, in connection with such transaction or transactions consists of shares of common stock 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.

(D) The Shares cease to be 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).

(E) Default by Company or any of its “significant subsidiaries” (as such term is defined in Article 1, Rule 1-02 of Regulation S-X under the Exchange Act) with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $100 million (or its foreign currency equivalent) in the aggregate of Company and/or any such significant subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable prior to its stated maturity or (ii) constituting a failure to pay the principal or interest of any such indebtedness when due and payable (after the expiration of all applicable grace periods) at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise.

(F) A final judgment or judgments for the payment of $100 million (or its foreign currency equivalent) or more (excluding any amounts covered by insurance) in the aggregate rendered against Company or any of its “significant subsidiaries” (as such term is defined in Article 1, Rule 1-02 of Regulation S-X under the Exchange Act), which judgment is not discharged, bonded, paid, waived or stayed within 60 days after (I) the date on which the right to appeal thereof has expired if no such appeal has commenced, or (II) the date on which all rights to appeal have been extinguished.

(G) Dealer, despite using commercially reasonable efforts, is unable or reasonably determines 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).

(h) 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 secured by any collateral. Obligations under the Transaction shall not be set off by either party against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise. For the avoidance of doubt and notwithstanding anything to the contrary provided in this Section 9(h), in the event of bankruptcy or liquidation of either Company or Dealer, neither party shall have the right to set off any obligation that it may have to the other party under the Transaction against any obligation such other party may have to it, whether arising under the Agreement, this Confirmation or any other agreement between the parties hereto, by operation of law or otherwise.

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

(except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to all holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that is within Company’s control, or (iii) an Event of Default in which Company is the Defaulting Party or a 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 commercially reasonable 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(j)(i) below, in satisfaction, subject to Section 9(j)(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(j)(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(j)(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(j)(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(j)(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.

(j) Registration/Private Placement Procedures . If, in the reasonable opinion of Dealer, 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(a)(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(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Dealer (or any such affiliate of Dealer). Company shall use its best efforts to cause the Private Placement Settlement of such Restricted Shares to 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(i) above) or premium to 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. 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 or premium, as the case may be, 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(i) 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(i) above or (y) the Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants) and ending on 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). 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 Business 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. 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. 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 use its best efforts to 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.

(k) 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.

(l) 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.

(m) 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.

(n) 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.

(o) Maximum Share Delivery .

(i) Notwithstanding any other provision of this Confirmation, the Agreement or the Equity Definitions, in no event will Company at any time be required to deliver a number of Shares greater than 13,718,636 (the “ Maximum Number of Shares ”) to Dealer in connection with the Transaction.

(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 (x) the number of Shares or Restricted Shares to be delivered would require the approval of Company’s shareholders (as required by Rule 312.03 of the New York Stock Exchange Rules (“ Rule 312.03 ”) or (y) Company has insufficient authorized but unissued Shares that are not reserved for other transactions (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(o)(ii), when, and to the extent that, (1) in the case of (x), Company shall have obtained either such required shareholder approval under Rule 312.03 or a waiver from the New York Stock Exchange, waiving the application of Rule 312.03 to Company’s issuance of Shares or Restricted Shares, and (2) in the case of (y), (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(o)(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. To the extent Company’s issuance of Shares or Restricted Shares requires the approval of Company’s shareholders as required by Rule 312.03, Company shall use its reasonable best efforts to obtain either such required shareholder approval or a waiver from the New York Stock Exchange, waiving the application of Rule 312.03 to Company’s issuance of Shares or Restricted 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.

(p) 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 determines, in good faith and in its commercially reasonable judgment, that such extension is reasonably necessary or appropriate to preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases of Shares in connection with its 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; provided that no such Expiration Date or other date of valuation, payment or delivery may be postponed or added more than 80 Exchange Business Days after the original Exercise Date or date of valuation, payment or delivery, as the case may be.

(q) 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.

(r) Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code (Title 11 of the United States Code) (the “ Bankruptcy Code ”), and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as described in the Bankruptcy Code, and (iii) each payment and delivery of cash, securities or other property hereunder to constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code.

(t) 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.

(u) Early Unwind . In the event the sale of the “Initial Securities” (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers 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.

(v) 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.

(w) Listing of Warrant Shares . Company shall have submitted an application for the listing of the Warrant Shares on the Exchange, and such application and listing shall have been approved by the Exchange, subject only to official notice of issuance, in each case, on or prior to the Premium Payment Date. Company agrees and acknowledges that such submission and approval 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.

(x) Tax Matters .

(i) Withholding Tax imposed on payments to non-US counterparties under the United States Foreign Account Tax Compliance Act . “Tax” and “Indemnifiable Tax”, each as defined in Section 14 of the Agreement, shall not include any U.S. federal withholding tax imposed or collected pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “ Code ”), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (a “ FATCA Withholding Tax ”). For the avoidance of doubt, a FATCA Withholding Tax is a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement.

(ii) Tax Documentation .

The Resale Period shall continue to enable the sale of the Make-whole Shares. 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. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Number of Shares.

		transaction or intention or the announcement of a withdrawal from, or the abandonment or discontinuation of, such a transaction or intention), as determined by the Calculation Agent.

Company agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “ Indemnified Person ”) from and against any and all losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person actually may become subject to, 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, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person, such Indemnified Person shall promptly notify Company in writing, and Company, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Company may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Company agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Company shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. 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 Company under such paragraph, 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 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. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

Representations and to provide such tax documentation as may be reasonably requested by Company to permit Company to determine that results described in clause (A) will not occur upon or after such transfer and assignment, (C) an Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment and (D) Dealer shall provide written notice to Company following any such Transfer. 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 provisions of Section 9(i) shall apply to any amount that is payable by Company to Dealer pursuant to this sentence as if Company 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 any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. 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 or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could 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 to the extent of any such performance.

in any quarterly dividend period of Company, 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 or lack thereof. “ Regular Dividend ” shall mean for any calendar quarter, USD 0.08 for the first regular cash dividend or distribution on the Shares for which the Ex-Dividend Date falls within such calendar quarter, and zero for any other dividend or distribution on the Shares for which the Ex-Dividend Date falls within the same calendar quarter.

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 commercially reasonable 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(j)(i) below, in satisfaction, subject to Section 9(j)(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(j)(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(j)(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(j)(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(j)(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.

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.

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). 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 Business 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. 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. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Number of Shares.

(l) 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.

(o) Maximum Share Delivery .

(i) Notwithstanding any other provision of this Confirmation, the Agreement or the Equity Definitions, in no event will Company at any time be required to deliver a number of Shares greater than 8,231,180 (the “ Maximum Number of Shares ”) to Dealer in connection with the Transaction.

(u) Early Unwind . In the event the sale of the “Initial Securities” (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers 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.

(x) Certain Tax Considerations.

(i) Dealer makes the following representations to Company: it is a national banking association organized under the laws of the United States and its U.S. taxpayer identification number is 13-5266470. It is “exempt” within the meaning of U.S. Treasury Regulations Sections 1.6041-3(p) and 1.6049-4(c) from information reporting on Form 1099 and backup withholding.

(ii) Dealer agrees to deliver to Company a valid, accurate and complete U.S. Internal Revenue Service Form W-9 (or any successor form) and any required attachments thereto (A) upon execution of this Confirmation, (B) promptly upon reasonable demand by Company and (C) promptly upon learning that any Form W-9 (or any successor thereto) previously provided by Dealer has become obsolete, invalid or incorrect.

(y) Withholding Tax imposed on payments to non-U.S. counterparties under the United States Foreign Account Tax Compliance Act . “Indemnifiable Tax” as defined in Section 14 of the Agreement shall not include any U.S. federal withholding tax imposed or collected pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (a “ FATCA Withholding Tax ”). For the avoidance of doubt, a FATCA Withholding Tax is a Tax

the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement.

(z) 871(m) . The parties agree that the definitions and provisions contained in the 2015 Section 871(m) Protocol, as published by ISDA, are incorporated into and apply to the Agreement solely for purposes of this Confirmation as if set forth in full herein.

(aa) Delivery or Receipt of Cash . For the avoidance of doubt, other than receipt of the Premium by Company, nothing in this Confirmation shall be interpreted as requiring Company to cash settle the Transaction, except in circumstances where cash settlement is within Company’s control (including, without limitation, where Company elects to deliver or receive cash, or where Company has made Private Placement Settlement unavailable due to the occurrence of events within its control) or in those circumstances in which holders of Shares would also receive cash.

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 the fully executed Confirmation via facsimile or e-mail.
