(a) On any Business Day during the period beginning on, and including, the Business Day immediately following the Issue Date to, but excluding, the second Scheduled Trading Day immediately preceding the Scheduled Mandatory Settlement Date or, if earlier, the second Scheduled Trading Day immediately preceding any Merger Termination Redemption Settlement Date and also excluding the Business Day immediately preceding any Installment Payment Date ( provided that the right to separate the Units shall resume after such Business Day), a Holder of a Unit may separate such Unit into its constituent Purchase Contract and Note (each such separated Purchase Contract and separated Note, a “ Separate Purchase Contract ” and “ Separate Note ,” respectively), which will thereafter trade under their respective CUSIP numbers (194014 403) and (194014 304), and that Unit will cease to exist. In order to cause the separation of a Global Unit into its component parts, a Beneficial Holder must comply with the applicable procedures of the Depositary. Following a valid exercise of separation rights by a Holder of Global Units, the Purchase Contract Agent or Trustee, as applicable, shall register (i) a decrease in the number of Units represented by the

If, however, such Unit is in the form of a Definitive Security in accordance with Section 3.09, the Holder thereof must deliver to the Purchase Contract Agent such Unit, together with a separation notice, in the form set forth in Attachment 1 to the form of Unit attached hereto as Exhibit A. Upon the receipt of such separation notice, the Company shall promptly cause delivery, in accordance with the delivery instructions set forth in such separation notice, of one Separate Purchase Contract and one Separate Note for each such Unit. Separate Purchase Contracts and Separate Notes will be transferable independently from each other.

(b) Holders which elect to separate the Note and related Purchase Contract in accordance with this Section 2.03 shall be responsible for any fees or expenses payable in connection with such separation, and neither the Company, the Purchase Contract Agent nor the Trustee shall be liable for any such fees or expenses.

THE UNITS AND PURCHASE CONTRACTS

Section 3.01. Amount and Denominations .

Each Unit was initially issued for a purchase price of $100.00 (before underwriting discounts and commissions), which represented an issue price of $15.6099 for the Note contained in each Unit and an issue price of $84.3901 for the Purchase Contract contained in each Unit.

Section 3.02. Rights and Obligations Evidenced by the Equity-Linked Securities . Each Equity-Linked Security shall evidence the number of Units or Separate Purchase Contracts, as the case may be, specified therein, with (a) each such Unit representing the rights and obligations of the Holder thereof and of the Company under one Purchase Contract, and the rights and obligations of the Holder thereof and of the Company under one Note, and (b) each such Separate Purchase Contract representing the rights and obligations of the Holder thereof and of the Company under one Separate Purchase Contract. In the case of a Unit, the Holder of such Unit shall, for all purposes hereunder and under the Indenture, be deemed to be the Holder of the Note and Purchase Contract that are components of such Unit.

Prior to the close of business on the Determination Date with respect to any Purchase Contract (whether such Purchase Contract is held as a component of a Unit or as a Separate Purchase Contract), the shares of Common Stock underlying such Purchase Contract shall not be outstanding, and such Purchase Contract shall not entitle the Holder thereof to any of the rights of a holder of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or to consent or to receive notice as a shareholder in respect of the meetings of shareholders or for the election of directors for any other matter, or any other rights whatsoever as a shareholder of the Company.

Section 3.03. Execution, Authentication, Delivery and Dating . Upon the execution and delivery of this Agreement, and at any time and from time to time thereafter, the Company may deliver Equity-Linked Securities executed by the Company and the Purchase Contract Agent as attorney-in-fact for the Holders of Purchase Contracts from time to time (in the case of Purchase Contracts), to the Purchase Contract Agent and Trustee (if applicable) for authentication on behalf of the Holders and delivery, together with an Issuer Order for authentication of such Equity-Linked Securities, and the Purchase Contract Agent and Trustee (if applicable) in accordance with such Issuer Order shall authenticate on behalf of the Holders and deliver such Equity-Linked Securities.

20

The Equity-Linked Securities shall be executed on behalf of the Company by any authorized officer of the Company and, in the case of the Purchase Contracts, shall be executed on behalf of the Holders by any authorized officer of the Purchase Contract Agent as attorney-in-fact for the Holders of Purchase Contracts from time to time. The signature of any such officer on the Equity-Linked Securities may be manual or facsimile.

Equity-Linked Securities bearing the manual or facsimile signature of an individual who was at any time the proper officer of the Company or, in the case of the Purchase Contracts, the Purchase Contract Agent, shall bind the Company and the Holders of Purchase Contracts, as the case may be, notwithstanding that such individual has ceased to hold such offices prior to the authentication and delivery of such Equity-Linked Securities or did not hold such offices at the date of such Equity-Linked Securities.

Each Equity-Linked Security shall be dated the date of its authentication.

No Equity-Linked Security shall be entitled to any benefit under this Agreement or be valid or obligatory for any purpose unless there appears on such Equity-Linked Security a certificate of authentication substantially in the form provided for herein executed by an authorized officer of the Purchase Contract Agent and Trustee (if applicable) by manual signature, and such certificate upon any Equity-Linked Security shall be conclusive evidence, and the only evidence, that such Equity-Linked Security has been duly authenticated and delivered hereunder.

Section 3.04. Temporary Equity-Linked Securities . Pending the preparation of any Definitive Equity-Linked Securities, the Company shall execute and deliver to the Purchase Contract Agent and, in the case of Units, Trustee, and the Purchase Contract Agent and, if applicable, Trustee shall authenticate on behalf of the Holders, and deliver, in lieu of such Definitive Equity-Linked Securities, temporary Equity-Linked Securities that are in substantially the form set forth in Exhibit A or Exhibit B hereto, as the case may be, with such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as may be required by the rules of any securities exchange on which the Units or Separate Purchase Contracts, as the case may be, are listed, or as may, consistently herewith, be determined by the officers of the Company executing such Equity-Linked Securities, as evidenced by their execution of the Equity-Linked Securities.

If temporary Equity-Linked Securities are issued, the Company will cause Definitive Equity-Linked Securities to be prepared without unreasonable delay. After the preparation of Definitive Equity-Linked Securities, the temporary Equity-Linked Securities shall be exchangeable for Definitive Equity-Linked Securities upon surrender of the temporary Equity-Linked Securities at the Corporate Trust Office, at the expense of the Company and without charge to the Holder or the Purchase Contract Agent. Upon surrender for cancellation of any one or more temporary Equity-Linked Securities, the Company shall execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and, if applicable, the Trustee shall authenticate on behalf of the Holder, and deliver in exchange therefor, one or more Definitive Equity-Linked Securities of like tenor and denominations and evidencing a like number of Units or Separate Purchase Contracts, as the case may be, as the temporary Equity-Linked Security or Equity-Linked Securities so surrendered. Until so exchanged, the temporary Equity-Linked Securities shall in all respects evidence the same benefits and the same obligations with respect to the Units or Separate Purchase Contracts, as the case may be, evidenced thereby as Definitive Equity-Linked Securities.

21

Section 3.05. Registration; Registration of Transfer and Exchange . The Company shall cause to be kept at the Corporate Trust Office a register (the “ Security Register ”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Equity-Linked Securities and of transfers of Equity-Linked Securities. The Purchase Contract Agent is hereby initially appointed security registrar (the “ Security Registrar ”) for the purpose of registration of Equity-Linked Securities and transfers of Equity-Linked Securities as provided herein. The Security Registrar shall record separately the registration and transfer of the Equity-Linked Securities evidencing Units and Separate Purchase Contracts.

Upon surrender for registration of transfer of any Equity-Linked Security at the Corporate Trust Office, the Company shall execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and Trustee shall authenticate on behalf of the designated transferee or transferees, and deliver, in the name of the designated transferee or transferees, one or more new Equity-Linked Securities of any authorized denominations, of like tenor, and evidencing a like number of Units or Separate Purchase Contracts, as the case may be.

At the option of the Holder, Equity-Linked Securities may be exchanged for other Equity-Linked Securities, of any authorized numbers and evidencing a like number of Units or Separate Purchase Contracts, as the case may be, upon surrender of the Equity-Linked Securities to be exchanged at the Corporate Trust Office. Whenever any Equity-Linked Securities are so surrendered for exchange, the Company shall execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and, in the case of Units, the Trustee shall authenticate on behalf of the Holder, and deliver the Equity-Linked Securities which the Holder making the exchange is entitled to receive.

All Equity-Linked Securities issued upon any registration of transfer or exchange of an Equity-Linked Security shall evidence the ownership of the same number of Units or Separate Purchase Contracts, as the case may be, and be entitled to the same benefits and subject to the same obligations, under this Agreement as the Units or Separate Purchase Contracts, as the case may be, evidenced by the Equity-Linked Security surrendered upon such registration of transfer or exchange.

Every Equity-Linked Security presented or surrendered for registration of transfer or exchange shall (if so required by the Purchase Contract Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Purchase Contract Agent duly executed by the Holder thereof, or its attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of an Equity-Linked Security, but the Company or the Purchase Contract Agent on behalf of the Company may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Equity-Linked Securities, other than any exchanges pursuant to Section 3.06 and Section 9.05 not involving any transfer.

22

Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent and, in the case of Units, the Trustee shall not be obligated to authenticate on behalf of the Holder or deliver any Equity-Linked Security in exchange for any other Equity-Linked Security presented or surrendered for registration of transfer or for exchange on or after the Business Day immediately preceding the Scheduled Mandatory Settlement Date or any earlier Settlement Date with respect to such Equity-Linked Security. In lieu of delivery of a new Equity-Linked Security, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Company shall, if a Settlement Date with respect to such Equity-Linked Security has occurred, deliver or cause to be delivered the shares of Common Stock deliverable and cash in lieu of any fractional share of Common Stock (and/or, in the case of a Merger Termination Redemption Settlement Date, make the required cash payment, if any) in respect of the Purchase Contracts evidenced by such Equity-Linked Security (together with the Separate Note, if such Equity-Linked Security is a Unit and if the Repurchase Right is not applicable or, if applicable, not exercised).

Section 3.06. Book-Entry Interests . The Units, on original issuance, will be issued in the form of one or more fully registered Global Units, to be delivered to the Depositary or its custodian by, or on behalf of, the Company. The Company hereby designates DTC as the initial Depositary. Such Global Units shall initially be registered on the books and records of the Company in the name of Cede & Co., the nominee of DTC, and no Beneficial Holder will receive a Definitive Unit representing such Beneficial Holder’s interest in such Global Unit, except as provided in Section 3.09. Unless and until definitive, fully registered Securities have been issued to Beneficial Holders pursuant to Section 3.09:

(i) the provisions of this Section 3.06 shall be in full force and effect;

(ii) the Company shall treat the Depositary for all purposes of this Agreement (including settling the Purchase Contracts and receiving approvals, votes or consents hereunder) as the Holder of the Global Units and Global Purchase Contracts and shall have no obligation to the Beneficial Holders;

(iii) to the extent that the provisions of this Section 3.06 conflict with any other provisions of this Agreement, the provisions of this Section 3.06 shall control; and

(iv) the rights of the Beneficial Holders shall be exercised only through the Depositary and shall be limited to those established by law and agreements between such Beneficial Holders and the Depositary or the Depositary Participants.

Section 3.07. Notices to Holders . Whenever a notice or other communication to the Holders is required to be given under this Agreement, the Company or the Company’s agent shall give such notices and communications to the Holders and, with respect to any Units or Purchase Contracts registered in the name of the Depositary or the nominee of the Depositary, the Company or the Company’s agent shall, except as set forth herein, have no obligations to the Beneficial Holders.

23

Section 3.08. Appointment of Successor Depositary . If the Depositary elects to discontinue its services as securities depositary with respect to the Units or Purchase Contracts, the Company may, in its sole discretion, appoint a successor Depositary with respect to such Units or such Purchase Contracts, as the case may be.

Section 3.09. Definitive Securities . If:

(i) the Depositary is at any time unwilling or unable to continue as depositary for the Global Securities or ceases to be a Clearing Agency registered under the Exchange Act, and a successor Depositary registered as a Clearing Agency under the Exchange Act is not appointed by the Company within 90 days; or

(ii) an Event of Default (as defined in the Indenture), or any failure on the part of the Company to observe or perform any covenant or agreement in the Purchase Contracts or the Purchase Contract Agreement, has occurred and is continuing and a Beneficial Holder requests that its Securities be issued in physical, certificated form,

then, in each case the Company shall execute, and the Purchase Contract Agent and/or the Trustee, as applicable, upon receipt of an Issuer Order for the authentication and delivery of Definitive Securities, shall authenticate and deliver Definitive Securities representing an aggregate number of Securities with respect to the Global Security or Securities representing such Securities (or representing an aggregate number of Securities equal to the aggregate number of Securities in respect of which such Beneficial Holder has requested the issuance of Definitive Securities pursuant to clause (ii) above) in exchange for such Global Security or Securities (or portion thereof). Each Definitive Security so delivered shall evidence Units or Purchase Contracts or Notes, as the case may be, of the same kind and tenor as the Global Security so surrendered in respect thereof. Notwithstanding the foregoing, the exchange of Global Notes for Notes in definitive form shall be governed by the Indenture.

Section 3.10. Mutilated, Destroyed, Lost and Stolen Securities . If any mutilated Equity-Linked Security is surrendered to the Purchase Contract Agent, together with such security or indemnity as may be reasonably required by the Company, the Purchase Contract Agent and the Trustee to hold them or any of their agents harmless, then the Company shall execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and, if applicable, the Trustee shall authenticate on behalf of the Holder, and deliver in exchange therefor, a new Equity-Linked Security, evidencing the same number of Units or Separate Purchase Contracts, as the case may be, and bearing a security number not contemporaneously outstanding.

If there shall be delivered to the Company, the Purchase Contract Agent and the Trustee (in the case of any Units) (i) evidence to their satisfaction of the destruction, loss or theft of any Equity-Linked Security, and (ii) such security or indemnity satisfactory to the Company, the Purchase Contract Agent and the Trustee at the expense of the Holder, then, in the absence of notice to the Company, the Purchase Contract Agent or the Trustee that such Equity-Linked

Such new Equity-Linked Security (and the Units or Separate Purchase Contracts, as applicable, evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits and be subject to all the obligations of this Agreement equally and proportionately with any and all other Equity-Linked Securities delivered hereunder.

The provisions of this Section 3.10 are exclusive and shall preclude, to the extent lawful, all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Equity-Linked Securities.

All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities and this Agreement shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Security). The rights of Beneficial Holders in Global Securities shall be exercised only through the Depositary subject to the applicable procedures. The Purchase Contract Agent, the Trustee, the Paying Agent and the Registrar shall be entitled to rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, DTC Participants and any Beneficial Holders.

Section 3.12. Cancellation . All Securities surrendered for separation or recreation and all Equity-Linked Securities surrendered for settlement or redemption or upon the registration of transfer or exchange of an Equity-Linked Security shall, if surrendered to any Person other than the Purchase Contract Agent, be delivered to the Purchase Contract Agent and, if not already cancelled, be promptly cancelled by it; provided, however, that the Purchase Contract Agent shall deliver any Notes or Separate Notes so surrendered to it to the Trustee and Paying Agent (as defined in the Indenture) for disposition in accordance with the provisions of the Indenture.

The Company may at any time deliver to the Purchase Contract Agent for cancellation any Equity-Linked Securities previously executed, authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Equity-Linked Securities so delivered shall, upon an Issuer Order, be promptly cancelled by the Purchase Contract Agent; provided , however , that if the Equity-Linked Securities so delivered are Units, the Purchase Contract Agent shall deliver the Notes comprising such Units to the Trustee and Paying Agent (as defined in the Indenture) for disposition in accordance with the provisions of the Indenture. No Equity-Linked Securities shall be executed, authenticated on behalf of the Holder and delivered in lieu of or in exchange for any Equity-Linked Securities cancelled as provided in this Section, except as expressly permitted by this Agreement. All cancelled Equity-Linked Securities held by the Purchase Contract Agent shall be disposed of in accordance with its customary practices.

If the Company or any Affiliate of the Company shall acquire any Equity-Linked Security, such acquisition shall not operate as a cancellation of such Equity-Linked Security unless and until such Equity-Linked Security is delivered to the Purchase Contract Agent for cancellation, in which case such Equity-Linked Security shall be accompanied by an Issuer Order and cancelled in accordance with the immediately preceding paragraph.

An Early Settlement shall be deemed for these purposes to be “in connection with” such Fundamental Change if the Holder delivers an Early Settlement Notice to the Purchase Contract Agent, and otherwise satisfies the requirements for effecting Early Settlement of its Purchase Contracts set forth in Section 4.06 hereof, during the period beginning on, and including, the Effective Date of the Fundamental Change and ending at the close of business on the 35th Business Day thereafter (or, if earlier, the second Scheduled Trading Day immediately preceding the Scheduled Mandatory Settlement Date) (the “ Fundamental Change Early Settlement Period ”).

(b) If a Holder complies with the requirements set forth in Section 4.07(a) and 4.06(b) to exercise the Fundamental Change Early Settlement Right before the close of business on any Business Day during the Fundamental Change Early Settlement Period, then that Business Day shall be considered the “ Fundamental Change Early Settlement Date .” If a Holder complies with the requirements set forth in set forth in Section 4.07(a) and 4.06(b) to exercise the Fundamental Change Early Settlement Right at or after the close of business on any Business Day during the Fundamental Change Early Settlement Period or at any time on a day during the Fundamental Change Early Settlement Period that is not a Business Day, then the next succeeding Business Day shall be considered the “ Fundamental Change Early Settlement Date .”

(e) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Fixed Settlement Rates are 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 Maximum Settlement Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Maximum Settlement Rate as so adjusted. The Fundamental Change Early Settlement Rates (and the Merger Termination Redemption Rates as described in Section 4.09) per Purchase Contract in the table below shall be adjusted in the same manner and at the same time as the Fixed Settlement Rates as set forth in Section 5.01.

(f) The following table sets forth the Fundamental Change Early Settlement Rate per Purchase Contract for each Stock Price and Effective Date set forth below:

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

(i) if the applicable Stock Price is between two Stock Prices in the table or the applicable Effective Date is between two Effective Dates in the table, the Fundamental Change Early Settlement Rate, or the Merger Termination Redemption Rate, as applicable, shall be determined by a straight-line interpolation between the Fundamental Change Early Settlement Rates or the Merger Termination Redemption Rates, as applicable, set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365- or 366-day year, as applicable;

(ii) if the applicable Stock Price is greater than $60.00 per share (subject to adjustment in the same manner and at the same time as the Stock Prices set forth in the column headings of the table above), the Fundamental Change Early Settlement Rate or the Merger Termination Redemption Rate, as applicable, shall be the Minimum Settlement Rate; or

(iii) if the applicable Stock Price is less than $5.00 per share (subject to adjustment in the same manner and at the same time as the Stock Prices set forth in the column headings of the table above, the “ Minimum Stock Price ”) the Fundamental Change Early Settlement Rate or the Merger Termination Redemption Rate, as applicable, shall be determined as if the Stock Price equaled the Minimum Stock Price, and using straight-line interpolation, as described in clause (i) of this Section 4.07(f), if the Effective Date is between two Effective Dates in the table.

32

The maximum number of shares of Common Stock deliverable under a Purchase Contract is 4.8054, subject to adjustment in the same manner and at the same time as the Fixed Settlement Rates as set forth under Section 5.01.

(g) [ Reserved .]

(h) Subject to satisfaction of the conditions set forth in Section 4.06(b) by a Holder with respect to any of its Purchase Contracts, the Company shall cause to be delivered a number of shares of Common Stock, or securities, cash or other property, as applicable, payable as a result of such Holder’s exercise of the Fundamental Change Early Settlement Right in accordance with the provisions set forth in Section 4.06(d), except that (i) such delivery shall be made on the second Business Day following the Fundamental Change Early Settlement Date, and (ii) the Person in whose name any shares of Common Stock or other securities, if applicable, shall be issuable following exercise of a Holder’s Fundamental Change Early Settlement Right shall be treated as the holder of record of such shares or other securities, if applicable, as of the close of business on the Fundamental Change Early Settlement Date.

(i) If a Holder exercises its Fundamental Change Early Settlement Right with respect to Purchase Contracts that are a component of Units, upon such Early Settlement in connection with a Fundamental Change, the Company shall execute and the Trustee shall authenticate (pursuant to the Indenture) on behalf of the Holder and deliver to the Holder thereof, at the expense of the Company, Separate Notes, in same form as the Notes comprising part of the Units, equal to the number of Purchase Contracts as to which Early Settlement in connection with a Fundamental Change was effected.

(j) If a Holder exercises its Fundamental Change Early Settlement Right with respect to Purchase Contracts represented by less than all the Purchase Contracts evidenced by a Security, upon such Early Settlement in connection with a Fundamental Change, the Company shall execute and the Purchase Contract Agent and Trustee shall authenticate on behalf of the Holder and deliver to the Holder thereof, at the expense of the Company, a Security evidencing the Purchase Contracts as to which Early Settlement in connection with a Fundamental Change was not effected.

(k) If a Holder does not elect to exercise the Fundamental Change Early Settlement Right, such Holder’s Purchase Contracts shall remain outstanding and shall be subject to normal settlement on any subsequent Settlement Date, including, if applicable, the provisions set forth in Section 5.01.

(a) If the closing of the Merger has not occurred on or prior to May 19, 2019, the Company may elect to redeem all, but not less than all, of the Outstanding Purchase Contracts, on the terms described in this Section 4.09, by delivering notice during the five Business Days immediately following May 19, 2019 in the manner specified in Section 4.09(b). If the Merger Agreement is terminated prior to May 19, 2019, the Company may elect to redeem all, but not less than all, of the Outstanding Purchase Contracts on

33

the terms described in this Section 4.09, by delivering notice on or prior to the 40th Scheduled Trading Day immediately preceding May 19, 2019 or during the five Business Days immediately following May 19, 2019 in the manner specified in Section 4.09(b) (any notice sent under this sentence or the immediately preceding sentence, a “ Merger Termination Redemption Notice, ” and a redemption under this sentence or the immediately preceding sentence, a “ Merger Termination Redemption ”).

(b) In the event of a Merger Termination Redemption, the Company shall provide the Purchase Contract Agent, the Trustee and the Holders of Units, Separate Purchase Contracts and Separate Notes with the Merger Termination Redemption Notice and issue a press release announcing its election.

(ii) the Scheduled Merger Termination Redemption Settlement Date;

(iii) if the Redemption Amount will be determined pursuant to Section 4.09(c)(i), the cash Redemption Amount;

(iv) if the Redemption Amount will be determined pursuant to Section 4.09(c)(ii), the Merger Termination Redemption Rate, and, if applicable, the number of shares of Common Stock that would otherwise be included in the applicable Redemption Amount that will be replaced with cash;

(x) any other information the Company determines to be appropriate.

In the event the Redemption Amount is determined pursuant to Section 4.09(c)(ii), if the Company does not specify a number of shares of Common Stock that will be replaced with cash in the Merger Termination Redemption Notice, the Company shall be deemed to have elected to settle the Redemption Amount solely in shares of Common Stock.

34

(c) In the event of a Merger Termination Redemption, the Company shall deliver the applicable Redemption Amount on the Merger Termination Redemption Settlement Date. The “ Redemption Amount ” shall mean:

(i) if the Merger Termination Redemption Stock Price is equal to or less than the Reference Price, an amount of cash per Purchase Contract equal to (x) the Stated Amount less (y) the applicable Repurchase Price; or

(ii) if the Merger Termination Redemption Stock Price is greater than the Reference Price, a number of shares of Common Stock per Purchase Contract equal to the Merger Termination Redemption Rate; provided that the Company may elect to pay cash in lieu of delivering any or all of such shares of Common Stock in an amount equal to the Merger Termination Redemption Rate multiplied by the Merger Termination Redemption Market Value.

The Company shall cause any shares referred to in clause (ii) above to be issued and delivered, together with payment of (a) any cash payable in lieu of fractional shares pursuant to Section 4.13 and (b) any dividends or distributions with respect to such shares constituting part of the Purchase Contract Settlement Fund (but without any interest thereon), to the applicable Holder by book-entry transfer or other appropriate procedures pursuant to Section 4.11. The Person in whose name any shares of the Common Stock shall be issuable pursuant to a Merger Termination Redemption shall be treated as the holder of record of such shares as of the close of business on:

(i) the date of the Merger Termination Redemption Notice, if the Company has elected (or is deemed to have elected) to settle the Redemption Amount solely in shares of Common Stock; or

(ii) the last Trading Day in the 20 consecutive Trading Day period used to determine the Merger Termination Redemption Market Value, if the Company has elected to pay cash in lieu of delivering a portion of any shares of Common Stock that would otherwise be included in the Redemption Amount.

(d) The table set forth in Section 4.07(f) shall be used to determine the “ Merger Termination Redemption Rate ” per Purchase Contract for each Merger Termination Redemption Stock Price, with references to “Stock Price” deemed to refer to “Merger Termination Redemption Stock Price,” references to “Fundamental Change Early Settlement Rate” deemed to refer to “Merger Termination Redemption Rate,” and references to “Effective Date” deemed to refer to the date of the related Merger Termination Redemption Notice.

(e) In the event of a Merger Termination Redemption with respect to Purchase Contracts that are a component of Units, upon the applicable Merger Termination Redemption Settlement Date, the Company shall execute and the Trustee shall authenticate (pursuant to the Indenture) on behalf of the Holder and deliver to the Holder thereof, at the expense of the Company, Separate Notes in the same form and in the same number as the Notes comprising part of the Units; provided, however , that if the Repurchase Date occurs prior to the Merger

35

The Company shall cause to be delivered the shares of Common Stock, securities, cash or other property deliverable as a result of any such acceleration of the Mandatory Settlement Date in accordance with the provisions set forth in Section 4.05, except that (i) such delivery shall be made on the accelerated Mandatory Settlement Date, and (ii) the Person in whose name any shares of Common Stock shall be issuable following such acceleration shall be treated as the holder of record of such shares as of the close of business on the Acceleration Date. Any claim for damages that Holders of the Purchase Contracts (whether as Separate Purchase Contracts or Purchase Contracts underlying Units) have for the Company’s failure to deliver Common Stock following a Bankruptcy Event as described in this Section 4.10 will rank pari passu with the claims of holders of the Common Stock in the relevant bankruptcy proceeding.

Section 4.12. Return of Purchase Contract Settlement Fund .

36

(i) the surrender of the relevant Units or Separate Purchase Contracts for settlement or redemption in accordance with the provisions hereof or receipt by the Company and the Purchase Contract Agent from such Holder of satisfactory evidence that such Units or Separate Purchase Contracts have been destroyed, lost or stolen, together with any indemnity that may be required by the Purchase Contract Agent and the Company; and

(ii) the passage of two years from the applicable Settlement Date, as the case may be, following which the Purchase Contract Agent shall pay to the Company such Holder’s share of such Common Stock and any dividends or distributions with respect to such shares constituting part of the Purchase Contract Settlement Fund; provided , however , that prior to receiving any such payment, the Company shall notify each such Holder that such property remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notice, any unclaimed balance of such property then remaining will be repaid to the Company. After payment to the Company, (A) Holders entitled to such property must look to the Company for payment as general creditors, unless applicable abandoned property law designates another Person, and (B) all liability of the Purchase Contract Agent with respect to such property shall cease.

Section 4.13. No Fractional Shares . No fractional shares or scrip certificates representing fractional shares of Common Stock shall be issued or delivered to Holders upon settlement or redemption of the Purchase Contracts. In lieu of any fractional shares of Common Stock that would otherwise be issuable upon settlement or redemption of any Purchase Contracts, a Holder of a Purchase Contract shall be entitled to receive an amount in cash equal to the fraction of a share of Common Stock, calculated on an aggregate basis in respect of the Purchase Contracts being settled or redeemed (provided that, so long as the Units are held as Global Units, the Company may elect to aggregate Units for purposes of these calculations on any basis permitted by the applicable procedures of the Depositary), multiplied by the Daily VWAP of the Common Stock on the Trading Day immediately preceding the applicable Settlement Date. To the extent the Purchase Contract Agent is obligated to make any payments on behalf of the Company pursuant to this Agreement, the Company shall provide the Purchase Contract Agent with sufficient funds to permit the Purchase Contract Agent to make all such cash payments in a timely manner.

ARTICLE V

ADJUSTMENTS

Section 5.01. Adjustments to the Fixed Settlement Rates . (a) Each Fixed Settlement Rate shall be subject to adjustment, without duplication, upon:

(i) Stock Dividends and Distributions . The issuance of Common Stock as a dividend or distribution to all or substantially all of the holders of Common Stock, or a subdivision or combination of Common Stock, in which event each Fixed Settlement Rate shall be adjusted based on the following formula:

37

Any adjustment made pursuant to this clause (i) will become effective immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share subdivision or share combination, as the case may be. If any dividend or distribution of the type described in this clause (i) is declared but not so paid or made, each Fixed Settlement Rate shall be immediately readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such dividend or distribution, to such Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared. For the purposes of this clause (i), the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such dividend or distribution or the open of business on the Effective Date for such share subdivision or share combination, as applicable, shall not include shares held in treasury by the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in treasury by the Company.

(ii) Issuance of Stock Purchase Rights . The issuance to all or substantially all holders of Common Stock of rights, options or warrants entitling such holders for a period expiring 45 calendar days or less from the date of issuance of such rights, options or warrants, to subscribe for or purchase shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such distribution per share of Common Stock, in which event each Fixed Settlement Rate shall be adjusted based on the following formula:

38

Any adjustment made pursuant to this clause (ii) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the close of business on the Record Date for such issuance. In the event that such rights, options or warrants described in this clause (ii) are not so issued, each Fixed Settlement Rate shall be immediately readjusted, effective as of the date the Board of Directors publicly announces its decision not to issue such rights, options or warrants, to such Fixed Settlement Rate that would then be in effect if such issuance had not been declared. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Common Stock are otherwise not delivered pursuant to such rights, options or warrants upon the exercise of such rights, options or warrants, each Fixed Settlement Rate shall be immediately readjusted, effective as of the date of such expiration or the date of such exercise, as the case may be, to such Fixed Settlement Rate that would then be in effect had the adjustment with respect to the issuance of such rights, options or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered.

In determining whether any rights, options or warrants entitle the Holders of Common Stock to subscribe for or purchase shares of Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such distribution per share of Common Stock, and in determining the aggregate price payable to exercise such rights, options or warrants, 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.

39

For the purposes of this clause (ii), the number of shares of Common Stock at the time outstanding shall not include shares held in treasury by the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not issue any such rights, warrants or options in respect of shares of Common Stock held in treasury by the Company.

(iii) Debt or Asset Distribution . (A) The dividend or other distribution to all or substantially all holders of Common Stock of shares of the Company’s Capital Stock (other than Common Stock), evidences of the Company’s indebtedness, assets or rights, options, or warrants to acquire the Company’s Capital Stock, indebtedness or assets, excluding

(1) any dividend or distribution as to which an adjustment was effected pursuant to Section 5.01(a)(i), Section 5.01(a)(ii) or Section 5.01(a)(iv); or

(2) any dividend or distribution in connection with a Spin-Off covered by this Section 5.01(a)(iii) relating to Spin-Offs; and

(3) any securities, cash or other property that is distributed in, and will constitute Exchange Property as a result of, a Reorganization Event,

in which event each Fixed Settlement Rate shall be adjusted based on the following formula:

If FMV (as defined above) is equal to or greater than SP ₀ (as defined above) or if the difference between SP ₀ and FMV is less than $1.00, in lieu of the foregoing adjustment,

40

provision shall be made for each Holder of a Unit or Separate Purchase Contract to receive, for each Unit or Separate Purchase Contract, at the same time and upon the same terms as holders of Common Stock, the kind and amount of Capital Stock, evidences of indebtedness, assets or rights, options or warrants that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Maximum Settlement Rate in effect on the Record Date for the dividend or distribution.

Any adjustment made pursuant to subparagraph (A) of clause (iii) above shall become effective immediately after the close of business on the Record Date for such dividend or distribution. In the event that such dividend or distribution is not so paid or made, each Fixed Settlement Rate shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such dividend or distribution, to such Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared.

If the transaction that gives rise to an adjustment pursuant to this Section 5.01(a)(iii) is a Spin-Off, then each Fixed Settlement Rate shall instead be adjusted based on the following formula:

Any adjustment made pursuant to this portion of clause (iii) will become effective immediately after the close of business on the last Trading Day of the 10 consecutive Trading Day period commencing on, and including, the effective date for the Spin-Off; provided that if any date for determining the number of shares of Common Stock issuable to a Holder occurs during the 10 consecutive Trading Day period commencing on, and including, the effective date

41

for the Spin-Off, references in the preceding paragraph to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between the beginning of the 10 consecutive Trading Day period and such determination date for purposes of determining the Fixed Settlement Rates. In the event that such distribution described in this clause (iii) is not so made, each Fixed Settlement Rate will be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such distribution, to such Fixed Settlement Rate that would then be in effect if such distribution had not been declared.

(iv) Cash Distributions . The dividend or distribution to all or substantially all holders of Common Stock of exclusively cash, excluding:

(1) any cash that is distributed in, and will constitute Exchange Property as a result of, a Reorganization Event (as described below); or

(2) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company,

in which event, each Fixed Settlement Rate shall be adjusted based on the following formula:

If C (as defined above) is equal to or greater than SP ₀ (as defined above) or if the difference between SP ₀ and C is less than $1.00, in lieu of the foregoing adjustment, provision shall be made for each Holder of a Unit or Separate Purchase Contract to receive, for each Unit or Separate Purchase Contract, at the same time and upon the same terms as holders of 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 Maximum Settlement Rate on the Record Date for such cash dividend or distribution.

42

Any adjustment made pursuant to this clause (iv) shall become effective immediately after the close of business on the Record Date for such dividend or distribution. In the event that any dividend or distribution described in this clause (iv) is not so made, each Fixed Settlement Rate shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such dividend or distribution, to such Fixed Settlement Rate which would then be in effect if such dividend or distribution had not been declared.

(v) Self Tender Offers and Exchange Offers . The Company or one or more Subsidiaries of the Company makes purchases of Common Stock pursuant to a tender offer or exchange offer by the Company or one of its Subsidiaries for Common Stock if the amount of cash and value of any other consideration included in the payment per share of Common Stock validly tendered or exchanged exceeds the average of the Last Reported Sale Prices per share of the Common Stock for 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 offer or exchange offer (the “ Tender Offer Expiration Date ”), in which event each Fixed Settlement Rate shall be adjusted based on the following formula:

43

Any adjustment made pursuant to this clause (v) will become effective immediately after the close of business on the last day of the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Tender Offer Expiration Date; provided that if any date for determining the number of shares of the Common Stock issuable to a Holder occurs during the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Tender Offer Expiration Date, references in the preceding paragraph to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between such Tender Offer Expiration Date and such determination date for purposes of determining the Fixed Settlement Rates.

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

(b) [Reserved] .

(c) Rights Plans . To the extent that the Company has a rights plan in effect with respect to the Common Stock on any Determination Date, Holders shall receive, in addition to the Common Stock, the rights under such rights plan, unless, prior to such Determination Date, the rights have separated from the Common Stock, in which case each Fixed Settlement Rate shall be adjusted at the time of separation of such rights as if the Company made a distribution to all holders of the Common Stock as described in Section 5.01(a)(iii), subject to readjustment in the event of the expiration, termination or redemption of such rights.

(d) Discretionary Adjustments . Subject to applicable law and the applicable listing standards of the NYSE (or any other securities exchange where the Common Stock is listed in accordance with the provisions of the Purchase Contract Agreement), the Company may make such increases in each Fixed Settlement Rate, in addition to any other increases required by this Article 5, as the Company determines to be in its best interests or the Company deems advisable to avoid or diminish any income tax to holders of the Common Stock resulting from any dividend or distribution of shares of Common Stock (or issuance of rights, options or warrants to acquire shares of Common Stock) or from any event treated as such for income tax purposes or for any other reason; provided that, in each case, the same proportionate adjustment must be made to each Fixed Settlement Rate.

(e) Calculation of Adjustments . All adjustments to each Fixed Settlement Rate shall be calculated to the nearest 1/10,000th of a share of Common Stock. No adjustment in a Fixed Settlement Rate shall be required unless such adjustment would require an increase or decrease of at least one percent therein. If any adjustment is not required to be made by reason

44

of this Section 5.01(e), then such adjustment shall be carried forward and taken into account in any subsequent adjustment; provided that on each Determination Date (including any date for determining the amount of cash payable in connection with a Merger Termination Redemption), adjustments to each Fixed Settlement Rate shall be made with respect to any such adjustment carried forward and which has not been taken into account before such Determination Date.

(f) Adjustments to Prices Over a Period. Whenever the Company is required to calculate the Last Reported Sale Prices, the Daily VWAPs or any other prices or amounts over a span of multiple days (including, without limitation, the Applicable Market Value, the Merger Termination Redemption Market Value, the Stock Price or the Merger Termination Redemption Stock Price), the Board of Directors shall make appropriate adjustments, if any, to each to account for any adjustment to the Fixed Settlement Rates if the related Record Date, Ex-Date, effective date or Tender Offer Expiration Date occurs during the period in which the Last Reported Sale Prices, the Daily VWAPs or such other prices or amounts are to be calculated.

(g) Limitation on Adjustments . No adjustment to the Fixed Settlement Rates shall be made if Holders of Units or any separate Purchase Contracts 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 Purchase Contracts, in the transaction that would otherwise give rise to an adjustment without having to settle the Purchase Contracts as if such Holder held a number of shares of the Common Stock equal to the Maximum Settlement Rate, multiplied by the number of Purchase Contracts held by such Holder. In addition, the Fixed Settlement Rates shall only be adjusted as set forth above and shall not be adjusted:

(A) 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;

(B) upon the issuance of any shares of Common Stock or rights, options or warrants 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 its Subsidiaries;

(C) upon the repurchase of any shares of Common Stock pursuant to an open market share repurchase program or other buyback transaction that is not a tender offer or exchange offer described in clause 5.01(a)(v) hereof;

(D) for the sale or issuance of shares of Common Stock, or securities convertible into or exercisable for shares of Common Stock, for cash, including at a price per share less than the Fair Market Value thereof or otherwise or in an acquisition, except as described in Sections 5.01(a)(i) through (v) hereof;

(E) for a third-party tender offer;

45

(F) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Issue Date; or

(G) solely for a change in, or elimination of, the par value of the Common Stock.

(h) Notice of Adjustment . Whenever the Fixed Settlement Rates are adjusted, the Company shall:

(i) prepare and transmit to the Purchase Contract Agent an Officer’s Certificate setting forth such adjusted Fixed Settlement Rates and/or the adjusted Fundamental Change Settlement Rates and the adjusted Merger Termination Redemption Rates, the method of calculation thereof in reasonable detail and the facts requiring such adjustment and upon which such adjustment is based;

(ii) within five Business Days following the occurrence of an event that requires an adjustment to the Fixed Settlement Rates, the Fundamental Change Settlement Rates and/or the adjusted Merger Termination Redemption Rates (or if the Company is not aware of such occurrence, as soon as practicable after becoming so aware), provide, or cause to be provided, a written notice to the Holders of the occurrence of such event; and

(iii) within five Business Days following the determination of such adjusted Fixed Settlement Rates, Fundamental Change Settlement Rates and/or the adjusted Merger Termination Redemption Rates provide, or cause to be provided, to the Holders a statement setting forth in reasonable detail the method by which the adjustment to such Fixed Settlement Rates, the Fundamental Change Settlement Rates and/or the adjusted Merger Termination Redemption Rates was determined and setting forth such adjusted Fixed Settlement Rates, Fundamental Change Settlement Rates and/or the adjusted Merger Termination Redemption Rates and the facts requiring such adjustment and upon which such adjustment is based.

(iv) Each adjustment to each Fixed Settlement Rate pursuant to this Section 5.01 will result in a corresponding adjustment to the Early Settlement Rate.

Section 5.02. Reorganization Events . (a) In the event of:

(i) any consolidation or merger of the Company with or into another Person (other than a merger or consolidation in which the Company is the continuing or surviving corporation and in which the Common Stock outstanding immediately prior to the merger or consolidation is not exchanged for cash, securities or other property of the Company or another Person);

(ii) any sale, transfer, lease or conveyance to another Person of all or substantially all of the property and assets of the Company;

46

(iii) any reclassification of Common Stock into securities, including securities other than Common Stock; or

(iv) any statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition);

in each case, as a result of which the Common Stock would be converted into, or exchanged for, securities, cash or other property (each, a “ Reorganization Event ”), each Purchase Contract outstanding immediately prior to such Reorganization Event shall, without the consent of Holders, become a contract to purchase the kind of securities, cash and/or other property (the “ Exchange Property ”) that a holder of Common Stock would have been entitled to receive immediately prior to such Reorganization Event and, prior to or at the effective time of such Reorganization Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Purchase Contract Agent and the Trustee a supplemental agreement permitted under Section 9.01(iv) amending this Agreement and the Purchase Contracts to provide for such change in the right to settle the Purchase Contracts. For purposes of the foregoing, the type and amount of Exchange Property in the case of any Reorganization Event that 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 shareholder election) will be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Common Stock. The Company shall notify the Purchase Contract Agent in writing of such weighted average as soon as practicable after such determination is made. The number of units of Exchange Property the Company shall deliver for each Purchase Contract settled or redeemed (if the Company elects not to deliver solely cash in respect of a Merger Termination Redemption) following the effective date of such Reorganization Event shall be equal to the number of shares of Common Stock that the Company would otherwise be required to deliver as determined based on the Fixed Settlement Rates then in effect on the applicable Determination Date, or such other settlement rates or redemption rates as provided herein (without any interest thereon and without any right to dividends or distributions thereon which have a record date that is prior to the close of business on the Determination Date). Each Fixed Settlement Rate shall be determined based upon the Applicable Market Value of a unit of Exchange Property that a holder of one share of Common Stock would have received in such Reorganization Event.

For purposes of this Section 5.02(a), “ Applicable Market Value ” shall be deemed to refer to the Applicable Market Value of the Exchange Property and such value shall be determined (A) in the case of any publicly traded securities that comprise all or part of the Exchange Property, based on the Daily VWAP of such securities, as determined by the Company in a commercially reasonable manner and in good faith (B) in the case of any cash that comprises all or part of the Exchange Property, based on the amount of such cash and (C) in the case of any other property that comprises all or part of the Exchange Property, based on the value of such property, as determined by a nationally recognized independent investment banking firm retained by the Company for this purpose. For purposes of this Section 5.02(a), the term “ Daily VWAP ” shall be determined by reference to the definition of Daily VWAP as if references therein to Common Stock were to such publicly traded securities that comprise all or part of the Exchange Property. For purposes of this Section 5.02(a), references to Common Stock in the definition of “ Trading Day ” shall be replaced by references to any publicly traded securities that comprise all or part of the Exchange Property.

47

If the Exchange Property in respect of any Reorganization Event includes, in whole or in part, securities of another Person, such supplemental agreement described in the second immediately preceding paragraph shall be executed by such other Person and shall (x) provide for anti-dilution and other adjustments that shall be as nearly equivalent as practicable, as determined by the officer of the Company executing such supplemental agreement, to the adjustments provided for in this Article 5, and (y) otherwise modify the terms of this Agreement and the Purchase Contracts to reflect the substitution of the applicable Exchange Property for the Common Stock (or other Exchange Property then underlying the Purchase Contracts). In establishing such anti-dilution and other adjustments referenced in the immediately preceding sentence, such officer shall act in a commercially reasonable manner and in good faith.

(b) In the event the Company shall execute a supplemental agreement pursuant to Section 5.02(a), the Company shall promptly file with the Purchase Contract Agent an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise the Exchange Property after any such Reorganization Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly notify Holders thereof. The Company (or any successor) shall, within 20 days of the occurrence of any Reorganization Event or, if earlier, within 20 days of the execution of any supplemental agreement pursuant to Section 5.02(a), provide written notice to the Purchase Contract Agent and Holders of such occurrence of such event and of the kind and amount of the cash, securities or other property that constitute the Exchange Property and of the execution of such supplemental agreement, if applicable. Failure to deliver such notice shall not affect the operation of this Section 5.02 or the legality or validity of any such supplemental agreement.

(c) The Company shall not become a party to any Reorganization Event unless its terms are consistent with this Section 5.02. None of the foregoing provisions shall affect the right of a Holder of Purchase Contracts to effect Early Settlement pursuant to Section 4.06 and Section 4.07 prior to the effective date of such Reorganization Event.

(d) The above provisions of this Section 5.02 shall similarly apply to successive Reorganization Events and the provisions of Section 5.01 shall apply to any shares of Capital Stock of the Company (or any successor) received by the holders of Common Stock in any such Reorganization Event.

ARTICLE VI

CONCERNING THE HOLDERS OF PURCHASE CONTRACTS

Section 6.01. Evidence of Action Taken by Holders . Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by a specified percentage of number of Purchase Contracts may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Holders in Person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or

48

instruments are delivered to the Purchase Contract Agent. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement and (subject to Section 8.01 and Section 8.03) conclusive in favor of the Purchase Contract Agent and the Company, if made in the manner provided in this Article 6.

Section 6.02. Proof of Execution of Instruments and of Holding of Securities . Subject to Section 8.01 and Section 8.03, the execution of any instrument by a Holder or his agent or proxy may be proved in the following manner:

(a) The fact and date of the execution by any Holder of any instrument may be proved by the certificate of any notary public or other officer of any jurisdiction authorized to take acknowledgments of deeds or administer oaths that the Person executing such instruments acknowledged to him the execution thereof, or by an affidavit of a witness to such execution sworn to before any such notary or other such officer. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute sufficient proof of the authority of the Person executing the same.

(b) The ownership of the Units and the Purchase Contracts shall be proved by the Security Register or by a certificate of the Security Registrar.

Section 6.03. Purchase Contracts Deemed Not Outstanding . In determining whether the Holders of the requisite number of Outstanding Purchase Contracts have concurred in any direction, consent or waiver under this Agreement, Purchase Contracts which are owned by the Company or by any Affiliate of the Company with respect to which such determination is being made shall be disregarded and deemed not to be Outstanding Purchase Contracts for the purpose of any such determination, except that for the purpose of determining whether the Purchase Contract Agent shall be protected in relying on any such direction, consent or waiver only Purchase Contracts which a Responsible Officer of the Purchase Contract Agent knows are so owned shall be so disregarded. Purchase Contracts so owned which have been pledged in good faith may be regarded as Outstanding Purchase Contracts if the pledgee establishes to the satisfaction of the Purchase Contract Agent the pledgee’s right so to act with respect to such Purchase Contracts and that the pledgee is not the Company or any Affiliate of the Company. In case of a dispute as to such right, the advice of counsel shall be fully protected in respect of any decision made by the Purchase Contract Agent in accordance with such advice. Upon request of the Purchase Contract Agent, the Company shall furnish to the Purchase Contract Agent promptly an Officer’s Certificate listing and identifying all Purchase Contracts, 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 8.01 and Section 8.03, the Purchase Contract Agent shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Purchase Contracts not listed therein are Outstanding Purchase Contracts for the purpose of any such determination.

Section 6.04. Right of Revocation of Action Taken . At any time prior to (but not after) the evidencing to the Purchase Contract Agent, as provided in Section 6.01, of the taking of any action by the Holders of the percentage of the number of Purchase Contracts specified in this Agreement in connection with such action, any Holder of a Purchase Contract the serial number of which is shown by the evidence to be included among the serial numbers of the Purchase

49

Contracts the Holders of which have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Article 6, revoke such action so far as concerns such Purchase Contract; provided that such revocation shall not become effective until three Business Days after such filing. Except as aforesaid, any such action taken by the Holder of any Purchase Contract shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Purchase Contract and of any Purchase Contracts issued in exchange or substitution therefor or on registration of transfer thereof, irrespective of whether or not any notation in regard thereto is made upon any such Purchase Contract. Any action taken by the Holders of the percentage of the number of Purchase Contracts specified in this Agreement in connection with such action shall be conclusively binding upon the Company, the Purchase Contract Agent, the Trustee and the Holders of all the Purchase Contracts affected by such action.

Section 6.05. Record Date for Consents and Waivers . The Company may, but shall not be obligated to, establish a record date for the purpose of determining the Persons entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Agreement to be given made or taken by Holders of Purchase Contracts. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and any such Persons, shall be entitled to give, make or take any such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holder remains a Holder after such record date; provided , however , that unless such waiver or consent is obtained from the Holders, or duly designated proxies, of the requisite number of Outstanding Purchase Contracts prior to the date which is the 120th day after such record date, any such waiver or consent previously given shall automatically and, without further action by any Holder be cancelled and of no further effect.

ARTICLE VII

REMEDIES

Section 7.01. Unconditional Right of Holders to Receive Shares of Common Stock . Each Holder of a Purchase Contract (whether or not included in a Unit) shall have the right, which is absolute and unconditional, to receive the shares of Common Stock (and/or, in the case of a Merger Termination Redemption, any cash included in the Redemption Amount) pursuant to such Purchase Contract and to institute suit for the enforcement of any such right to receive the shares of Common Stock (and/or, in the case of a Merger Termination Redemption, any cash included in the Redemption Amount), and such right shall not be impaired without the consent of such Holder.

Section 7.02. Notice To Purchase Contract Agent; Limitation On Proceedings . Holders of not less than 25% of Outstanding Purchase Contracts, by notice given to the Purchase Contract Agent, may request that Purchase Contract Agent to institute proceedings with respect to a default relating to any covenant hereunder; provided , subject to Section 7.08 and Article VIII hereof, the Purchase Contract Agent shall have no obligation to institute any such proceeding. No Holder of Purchase Contracts may institute any proceedings, judicial or otherwise, with respect to this Agreement or for any remedy hereunder, except in the case of failure of the Purchase Contract Agent, for 60 days, to act after the Purchase Contract Agent has received a written request to institute proceedings in respect of a default with respect to any

50

covenant hereunder from the Holders of not less than 25% of the Outstanding Purchase Contracts, as well as an offer of indemnity reasonably satisfactory to the Purchase Contract Agent. This provision will not prevent any Holder of Purchase Contracts from instituting suit for the delivery of Common Stock (and/or, in the case of a Merger Termination Redemption, any cash included in the Redemption Amount) deliverable upon settlement or redemption of the Purchase Contracts on any Settlement Date.

Section 7.03. Restoration of Rights and Remedies . If any Holder or the Purchase Contract Agent has instituted any proceeding to enforce any right or remedy under this Agreement and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to such Holder or the Purchase Contract Agent, then and in every such case, subject to any determination in such proceeding, the Company and such Holder or the Purchase Contract Agent shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of such Holder shall continue as though no such proceeding had been instituted.

Section 7.04. Rights and Remedies Cumulative . Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.10, no right or remedy herein conferred upon or reserved to the Holders or the Purchase Contract Agent is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 7.05. Delay or Omission Not Waiver . No delay or omission of any Holder or the Purchase Contract Agent to exercise any right or remedy upon a default hereunder shall impair any such right or remedy or constitute a waiver of any such right. Every right and remedy given by this Article or by law to the Holders or the Purchase Contract Agent may be exercised from time to time, and as often as may be deemed expedient, by such Holders or the Purchase Contract Agent.

Section 7.06. Undertaking for Costs . All parties to this Agreement agree, and each Holder of a Purchase Contract, by its acceptance of such Purchase Contract shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Purchase Contract Agent for any action taken, suffered or omitted by it as Purchase Contract Agent, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and costs against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section shall not apply to any suit instituted by (a) the Purchase Contract Agent, or (b) any Holder for the enforcement of the right to receive shares of Common Stock or other Exchange Property issuable upon settlement or the Redemption Amount payable or deliverable, as the case may be, upon redemption, as the case may be, of the Purchase Contracts held by such Holder.

51

Section 7.07. Waiver of Stay or Execution Laws . The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or assume or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Agreement; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Purchase Contract Agent or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 7.08. Control by Majority . The Holders of not less than a majority in number of the Outstanding Purchase Contracts shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Purchase Contract Agent, or of exercising any trust or power conferred upon the Purchase Contract Agent; provided that the Purchase Contract Agent has received indemnity reasonably satisfactory to it. Notwithstanding the foregoing, the Purchase Contract Agent may refuse to follow any direction that is in conflict with any law or the Purchase Contract Agreement, or that may involve it in personal liability.

ARTICLE VIII

[REVERSE OF PURCHASE CONTRACT]

Each Purchase Contract evidenced hereby is governed by a Purchase Contract Agreement, dated as of January 11, 2019 (as may be supplemented from time to time, the “ Purchase Contract Agreement ”), between Colfax Corporation, a Delaware corporation (the “ Company ”) and U.S. Bank National Association, as Purchase Contract Agent (including its successors hereunder, the “ Purchase Contract Agent ”), as Trustee under the Indenture and as attorney-in-fact for the Holders of Purchase Contracts from time to time. Reference is hereby made to the Purchase Contract Agreement and supplemental agreements thereto for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Purchase Contract Agent, the Company and the Holders and of the terms upon which the Purchase Contracts are, and are to be, executed and delivered.

Each Purchase Contract evidenced hereby obligates the Company to deliver to the Holder of this Purchase Contract, on the Mandatory Settlement Date, a number of shares of Common Stock equal to the Settlement Rate, unless such Purchase Contract has settled or been redeemed prior to the Mandatory Settlement Date, in either case, pursuant to the terms of the Purchase Contract Agreement.

No fractional shares of Common Stock will be issued upon settlement or redemption of Purchase Contracts, as provided in Section 4.13 of the Purchase Contract Agreement.

The Purchase Contracts are issuable only in registered form and only in denominations of a single Purchase Contract and any integral multiple thereof. The transfer of any Purchase Contract will be registered and Purchase Contracts may be exchanged as provided in the Purchase Contract Agreement.

The Purchase Contracts are initially being issued as part of the 5.75% Tangible Equity Units (the “ Units ”) issued by the Company pursuant to the Purchase Contract Agreement. Holders of the Units have the right to separate such Units into their constituent parts, consisting of Separate Notes and Separate Purchase Contracts, during the times, and under the circumstances, described in the Purchase Contract Agreement. Following separation of any Unit into its constituent parts, the Separate Purchase Contracts are transferable independently from the Separate Notes. In addition, Separate Purchase Contracts can be recombined with Separate Notes to recreate Units, as provided for in the Purchase Contract Agreement.

The Holder of this Purchase Contract, by its acceptance hereof, authorizes the Purchase Contract Agent to enter into and perform the Purchase Contract Agreement on its behalf as its attorney-in-fact and agrees to be bound by the terms and provisions thereof.

Subject to certain exceptions set forth in the Purchase Contract Agreement, the provisions of the Purchase Contract Agreement may be amended with the consent of the Holders of a majority of the Purchase Contracts.

The Purchase Contracts shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company, the Purchase Contract Agent, and any agent of the Company or the Purchase Contract Agent, may treat the Person in whose name this Purchase Contract is registered as the owner of the Purchase Contracts, evidenced hereby, for the purpose of performance of the Purchase Contracts evidenced by such Purchase Contracts and for all other purposes whatsoever, and neither the Company nor the Purchase Contract Agent, nor any agent of the Company or the Purchase Contract Agent, shall be affected by notice to the contrary.

The Purchase Contracts shall not entitle the Holder to any of the rights of a holder of the Common Stock or other Exchange Property, except as provided by the Purchase Contract Agreement.

Each Purchase Contract (whether or not included in a Unit) is a security governed by Article 8 of the Uniform Commercial Code as in effect in the State of New York on the date hereof.

Unless a conformed copy of the Purchase Contract Agreement has been filed on the EDGAR system of the U.S. Securities and Exchange Commission, a copy of the Purchase Contract Agreement will be available for inspection at the offices of the Company.

In the event of any inconsistency between the provisions of this Purchase Contract and the provisions of the Purchase Contract Agreement, the Purchase Contract Agreement shall prevail.
