The purpose of this communication (this “Confirmation”) is to set forth the terms and conditions of the above-referenced transaction entered into on the Trade Date specified below (the “Transaction”) between Morgan Stanley & Co. International plc (“Dealer”) and Cubist Pharmaceuticals, Inc. (“Issuer”).  This communication constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below.

Disclosure of Agency Relationship

Morgan Stanley & Co. LLC (“MS&CO”) is acting as agent for Dealer and is acting as agent for Issuer as and to the extent required by Rule 15a-6 under the Exchange Act (as defined below), but MS&CO does not guarantee the performance of either party.  Additionally, (i) neither Dealer nor Issuer shall contact the other with respect to any matter relating to the Transaction without the direct involvement of MS&CO; (ii) MS&CO, Dealer and Issuer each hereby acknowledges that any transactions by Dealer or MS&CO with respect to the Transaction will be undertaken by Dealer as principal for its own account; (iii) all of the actions to be taken by Dealer and MS&CO in connection with the Transaction shall be taken by Dealer or MS&CO independently and without any advance or subsequent consultation with Issuer, except as otherwise stated herein; and (iv) MS&CO is hereby authorized to act as agent for Issuer only to the extent required to satisfy the requirements of Rule 15a-6 under the Exchange Act in respect of the Transaction.  For the avoidance of doubt, any performance by Dealer of its obligations hereunder solely to MS&CO shall not relieve Dealer of such obligations.  MS&CO’s performance to Issuer of Dealer’s obligations hereunder shall relieve Dealer of such obligations to the extent of such performance.  Any performance by Issuer of its obligations (including notice obligations) through or by means of MS&CO’s agency for Dealer shall constitute good performance of Issuer’s obligations hereunder to Dealer.

1.             This Confirmation is subject to, and incorporates, the definitions and provisions of the 2000 ISDA Definitions (including the Annex thereto) (the “2000 Definitions”) and the definitions and provisions of the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”, and together with the 2000 Definitions, the “Definitions”), in each case as published by the International Swaps and Derivatives Association, Inc. (“ISDA”).  In the event of any inconsistency between the 2000 Definitions and the Equity Definitions, the Equity Definitions will govern.  For purposes of the Equity Definitions, each reference herein to a Warrant shall be deemed to be a reference to a Call Option or an Option, as context requires.

This Confirmation evidences a complete and binding agreement between Dealer and Issuer as to the terms of the Transaction to which this Confirmation relates.  This Confirmation shall be subject to an agreement (the “Agreement”) in the form of the 2002 ISDA Master Agreement as if Dealer and Issuer had executed an agreement in such form (without any

Schedule except for (i) the election of US Dollars (“USD”) as the Termination Currency and (ii) the election that the “Cross Default” provisions of Section 5(a)(vi) shall apply to Issuer with a “Threshold Amount” of USD25 million (or USD50 million at such time as Issuer’s senior unsecured indebtedness is rated BBB+ or greater by Standard & Poor’s Ratings Services (“S&P”) or Baa1 or greater by Moody’s Investors Service, Inc. (“Moody’s”), in each case, with a stable or positive outlook (or if Issuer’s senior unsecured indebtedness is not rated at such time by S&P or Moody’s, Issuer’s issuer rating is BBB+ or greater from S&P or Baa1 or greater from Moody’s, in each case, with a stable or positive outlook))). For the avoidance of doubt, the Transaction shall be the only transaction under the Agreement.  The parties acknowledge that the Transaction to which this Confirmation relates is not governed by, and shall not be treated as a transaction under, any other ISDA Master Agreement entered into between the parties from time to time.

All provisions contained in, or incorporated by reference to, the Agreement will govern this Confirmation except as expressly modified herein.  In the event of any inconsistency between this Confirmation and either the Definitions or the Agreement, this Confirmation shall govern, and in the event of any inconsistency between either the Definitions or this Confirmation and the Agreement, the Definitions or this Confirmation, as the case may be, shall govern.  For the avoidance of doubt, except to the extent of an express conflict, the application of any provision of this Confirmation, the Definitions or the Agreement, shall not be construed to exclude or limit the application of any other provision of this Confirmation, the Definitions or the Agreement.

2.             The Transaction is a Warrant Transaction, which shall be considered a Share Option Transaction for purposes of the Equity Definitions.  The terms of the particular Transaction to which this Confirmation relates are as follows:

(viii)        Issuer shall not take any action to decrease the number of Available Shares below the Capped Number (each as defined below).

(ix)          The representations and warranties of Issuer set forth in Section 3 of the Agreement and Section 1 of the Purchase Agreement (the “Purchase Agreement”) dated as of September 4, 2013 among Issuer and Morgan Stanley & Co.

(xiii)        (a) The Shares of Issuer issuable from time to time upon exercise of the Warrants (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 Warrant following the exercise of the Warrant in accordance with the terms and conditions of the Warrant, 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 and (b) a number of Warrant Shares equal to the Capped Number has been accepted for listing or quotation on the Exchange, subject to notice of issuance.  In addition, Issuer shall ensure that at all times until its delivery obligations hereunder have been met in full that the total number of Shares reserved for issuance hereunder and, prior to receipt of the Required Stockholder Approval (as defined below), for issuance under any Other Warrant Transaction (as defined below), in the aggregate, is at least equal to the Capped Number.

8.             Miscellaneous:

(a)           Alternative Calculations and Issuer Payment on Early Termination and on Certain Extraordinary Events.  If Issuer shall owe Dealer any amount pursuant to Sections 12.2, 12.3, 12.6, 12.7 or 12.9 of the Equity Definitions or pursuant to Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Issuer shall have the right, in its sole discretion, to satisfy any such Payment Obligation by the Share Termination Alternative (as defined below) by giving irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 9:30 A.M. New York City time on the Merger Date, Tender Offer Date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable (“Notice of Share Termination”); provided that if Issuer does not elect to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its sole discretion, to elect to require Issuer to satisfy its Payment Obligation by the Share Termination Alternative, notwithstanding Issuer’s failure to elect or election to the contrary; and provided further that Issuer shall not have the right to so elect (but, for the avoidance of doubt, Dealer shall have the right to so elect) in the event of (i) an Insolvency, a Nationalization or a Merger Event, in each case, in which the consideration or proceeds to be paid to holders of Shares consists solely of cash or (ii) an Event of Default, a Termination Event or an Extraordinary Event, in each case, which resulted from an event or events within Issuer’s control.  Upon such Notice of Share Termination, the following provisions shall apply on the Scheduled Trading Day immediately following the Merger Date, the Tender Offer Date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable:

12

(b)           Payment by Dealer.  In the event that, following payment of the Premium, (i) an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event of Default (other than an Event of Default of the type described in Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Dealer owes to Issuer an amount pursuant to Section 6 of the Agreement, or (ii) Dealer owes to Issuer an amount pursuant to Article 12 of the Equity Definitions (including, for the avoidance of doubt, any amount payable in connection with an Extraordinary Event), such amount shall be deemed to be zero.

(c)           Additional Termination Events.  The occurrence of any of the following shall constitute an Additional Termination Event with respect to which the Transaction shall be the sole Affected Transaction and Issuer shall be the sole Affected Party and Dealer shall be the party entitled to designate an Early Termination Date; provided that with respect to any Additional Termination Event, Dealer may choose to treat part of the Transaction as the sole Affected Transaction, and, upon the termination of the Affected Transaction, a Transaction with terms identical to those set forth herein except with a Number of Warrants equal to the unaffected number of Warrants shall be treated for all purposes as the Transaction, which shall remain in full force and effect:

(i)            Dealer reasonably determines that it is advisable to terminate a portion of the Transaction so that Dealer’s related hedging activities will comply with applicable securities laws, rules or regulations;

13

(ii)           any Person (as defined below) acquires beneficial ownership (determined in accordance with Rule 13d-3 under the Exchange Act), directly or indirectly, through a purchase, merger or other acquisition transaction or series of transactions, of shares of Issuer’s capital stock entitling the Person to exercise 50% or more of the total voting power of all shares of Issuer’s capital stock entitled to vote generally in elections of directors, other than an acquisition by Issuer, any of Issuer’s subsidiaries and any of Issuer’s employee benefit plans;

(iii)          Issuer merges or consolidates with or into any other Person (other than a subsidiary of Issuer), another Person merges or consolidates with or into Issuer, or Issuer conveys, sells, transfers or leases all or substantially all of its assets to another Person in one transaction or a series of related transactions, other than any transaction:

(A)          that does not result in a reclassification, conversion, exchange or cancellation of the outstanding Shares; or

(B)          pursuant to which the holders of all classes of Issuer’s common equity immediately prior to such transaction have the entitlement to exercise, directly or indirectly, 50% or more of the total voting power of all classes of the capital stock of the continuing or surviving entity or transferee or parent thereof entitled to vote generally in the election of directors or managers of the continuing or surviving entity or transferee or parent thereof immediately after such transaction in substantially the same proportions as such entitlement immediately prior to such transaction;

(iv)          Issuer’s stockholders approve any plan or proposal for the liquidation or dissolution of Issuer; or

(v)           the Shares cease to be listed on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors).

Notwithstanding the foregoing, a transaction or transactions set forth in clause (ii) or (iii) above will not constitute an Additional Termination Event if (A) at least 90% of the consideration paid for the Shares (excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ or appraisal rights) in connection with such transaction or transactions otherwise constituting an Additional Termination Event 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 traded or quoted immediately following such transaction or transactions and (B) as a result of such transaction or transactions, the “Shares” are composed of such consideration (excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ or appraisal rights).

“Person” includes any syndicate or group that would be deemed to be a “person” under Section 13(d)(3) of the Exchange Act.

(d)           Registration/Private Placement Procedures.  (i)  If, in the reasonable judgment of Dealer, for any reason, any Shares or any securities of Issuer or its affiliates comprising any Share Termination Delivery Units deliverable to Dealer hereunder (any such Shares or securities, “Delivered Securities”) would not be immediately freely transferable by Dealer under Rule 144 under the Securities Act, then the provisions set forth in this Section 8(d) shall apply.  At the election of Issuer by notice to Dealer within one Exchange Business Day after the relevant delivery obligation arises, but in any event at least one Exchange Business Day prior to the date on which such delivery obligation is due, either (A) all Delivered Securities delivered by Issuer to Dealer shall be, at the time of such delivery, covered by an effective registration statement of Issuer for immediate resale by Dealer (such registration statement and the corresponding prospectus (the “Prospectus”) (including, without limitation, any sections describing the plan of distribution) in form and content commercially reasonably satisfactory to Dealer) or (B) Issuer shall deliver additional Delivered Securities so that the value of such Delivered Securities, as determined

14

by the Calculation Agent to reflect an appropriate liquidity discount, equals the value of the number of Delivered Securities that would otherwise be deliverable if such Delivered Securities were freely tradeable (without prospectus delivery) upon receipt by Dealer (such value, the “Freely Tradeable Value”); provided that Issuer may not make the election described in this clause (B) 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 delivery by Issuer to Dealer (or any Affiliate of Dealer designated by Dealer) of the Delivered Securities or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Delivered Securities by Dealer (or any such Affiliate of Dealer).  (For the avoidance of doubt, as used in this Section 8(d) only, the term “Issuer” shall mean the issuer of the relevant securities, as the context shall require.)

(ii)           If Issuer makes the election described in Section 8(d)(i)(A) above:

(A)          Dealer (or an Affiliate of Dealer designated by Dealer) shall be afforded a reasonable opportunity to conduct a due diligence investigation with respect to Issuer that is customary in scope for underwritten offerings of equity securities and that yields results that are reasonably satisfactory to Dealer or such Affiliate, as the case may be, in its discretion; and

(B)          Dealer (or an Affiliate of Dealer designated by Dealer) and Issuer shall enter into an agreement (a “Registration Agreement”) on commercially reasonable terms in connection with the public resale of such Delivered Securities by Dealer or such Affiliate substantially similar to underwriting agreements customary for underwritten offerings of equity securities, in form and substance reasonably satisfactory to Dealer or such Affiliate and Issuer, which Registration Agreement shall include, without limitation, provisions substantially similar to those contained in such underwriting agreements relating to the indemnification of, and contribution in connection with the liability of, Dealer and its Affiliates and Issuer, shall provide for the payment by Issuer of all reasonable and documented expenses in connection with such resale, including all registration costs and all reasonable fees and expenses of one counsel for Dealer, and shall provide for the delivery of accountants’ “comfort letters” to Dealer or such Affiliate with respect to the financial statements and certain financial information contained in or incorporated by reference into the Prospectus.

(iii)          If Issuer makes the election described in Section 8(d)(i)(B) above:

(A)          Dealer (or an Affiliate of Dealer designated by Dealer) and any potential institutional purchaser of any such Delivered Securities from Dealer or such Affiliate identified by Dealer shall be afforded a commercially reasonable opportunity to conduct a due diligence investigation in compliance with applicable law with respect to Issuer customary in scope for private placements of equity securities (including, without limitation, the right to have made available to them for inspection all financial and other records, pertinent corporate documents and other information reasonably requested by them);

(B)          Dealer (or an Affiliate of Dealer designated by Dealer) and Issuer shall enter into an agreement (a “Private Placement Agreement”) on commercially reasonable terms in connection with the private placement of such Delivered Securities by Issuer to Dealer or such Affiliate and the private resale of such shares by Dealer or such Affiliate, substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance reasonably satisfactory to Dealer and Issuer, which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements relating to the indemnification of, and contribution in connection with the liability of, Dealer and its Affiliates and Issuer, shall provide for the payment by Issuer of all reasonable and documented expenses in connection with such resale, including all reasonable fees and expenses of one counsel for Dealer, shall contain representations, warranties and agreements of Issuer reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales, and shall use best efforts to provide for the delivery of accountants’ “comfort letters” to Dealer or such Affiliate with respect to the financial statements and certain financial information

15

contained in or incorporated by reference into the offering memorandum prepared for the resale of such Shares; and

(C)          Issuer agrees that any Delivered Securities so delivered to Dealer, (i) may be transferred by and among Dealer and its Affiliates, and Issuer shall effect such transfer without any further action by Dealer and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed with respect to such Delivered Securities, Issuer shall promptly remove, or cause the transfer agent for such Shares or securities to remove, any legends referring to any such restrictions or requirements from such Delivered Securities upon delivery by Dealer (or such Affiliate of Dealer) to Issuer or such transfer agent of seller’s and broker’s representation letters customarily delivered by Dealer in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, without any further 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).

(D)          Issuer shall not take, or cause 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 Issuer to Dealer (or any Affiliate designated by Dealer) of the Shares or Share Termination Delivery Units, as the case may be, or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Shares or Share Termination Delivery Units, as the case may be, by Dealer (or any such Affiliate of Dealer).

(iv)          If Issuer makes the election described in clause (i)(B) of this paragraph (d), then Dealer or its Affiliate may sell such Shares or Share Termination Delivery Units, as the case may be, during a period (the “Resale Period”) commencing on the Exchange Business Day following delivery of such Shares or Share Termination Delivery Units, as the case may be, and ending on the Exchange Business Day on which Dealer completes the sale of all such Shares or Share Termination Delivery Units, as the case may be, or a sufficient number of Shares or Share Termination Delivery Units, as the case may be, so that the realized net proceeds of such sales exceed the Freely Tradeable Value (such amount of the Freely Tradeable Value, the “Required Proceeds”).  If any of such delivered Shares or Share Termination Delivery Units remain after such realized net proceeds exceed the Required Proceeds, Dealer shall return such remaining Shares or Share Termination Delivery Units to Issuer.  If the Required Proceeds exceed the realized net proceeds from such resale, Issuer shall transfer to Dealer by the open of the regular trading session on the Exchange on the Exchange Trading Day immediately following the last day of the Resale Period the amount of such excess (the “Additional Amount”) in cash or in a number of additional Shares or Share Termination Delivery Units, as the case may be, (“Make-whole Shares”) in an amount that, based on the Relevant Price on the last day of the Resale Period (as if such day was the “Valuation Date” for purposes of computing such Relevant Price), has a dollar value equal to the Additional Amount.  The Resale Period shall continue to enable the sale of the Make-whole Shares in the manner contemplated by this Section 8(d)(iv).  This provision shall be applied successively until the Additional Amount is equal to zero, subject to Section 8(i).

(e)           Amendments to Equity Definitions.  The following amendments shall be made to the Equity Definitions:

(i)            Section 11.2(a) of the Equity Definitions is hereby amended by deleting the words “a diluting or concentrative effect on the theoretical value of the relevant Shares” and replacing them with the words “an economic effect on the relevant Transaction”.

(ii)           The first sentence of Section 11.2(c) of the Equity Definitions, prior to clause (A) thereof, is hereby amended to read as follows: ‘(c) If “Calculation Agent Adjustment” is specified as the Method of Adjustment in the related Confirmation of a Share Option Transaction, then following the announcement or occurrence of any Potential Adjustment Event, the Calculation Agent will determine whether such Potential Adjustment Event has an economic effect on the Transaction and, if so, will (i) make appropriate adjustment(s), if any, to any one or more of:’ and, the portion of such sentence immediately preceding clause (ii) thereof is hereby amended by (x) replacing the words “a diluting or concentrative” with “an” in

16

the fifth line thereof, (y) deleting the words “diluting or concentrative effect” in the sixth to last line thereof and (z) replacing the phrase “(provided that no adjustments will be made to account solely for changes in volatility, expected dividends, stock loan rate or liquidity relative to the relevant Shares)” with the phrase “(and, for the avoidance of doubt, adjustments may be made to account solely for changes in volatility, expected dividends, stock loan rate or liquidity relative to the relevant Shares)”.

(iii)          Section 11.2(e)(vii) of the Equity Definitions are hereby amended by deleting the words “diluting or concentrative effect on the theoretical value of the relevant Shares” and replacing them with the words “an economic effect on the relevant Transaction”.

(iv)          Section 12.9(b)(iv) of the Equity Definitions is hereby amended by (A) deleting (1) subsection (A) in its entirety, (2) the phrase “or (B)” following subsection (A) and (3) the phrase “in each case” in subsection (B); (B) replacing “will lend” with “lends” in subsection (B); and (C) replacing the phrase “neither the Non-Hedging Party nor the Lending Party lends Shares” with the phrase “such Lending Party does not lend Shares” in the penultimate sentence.

(v)           Section 12.9(b)(v) of the Equity Definitions is hereby amended by (A) adding the word “or” immediately before subsection “(B)” and deleting the comma at the end of subsection (A); and (B)(1) deleting subsection (C) in its entirety, (2) deleting the word “or” immediately preceding subsection (C) and (3) replacing in the penultimate sentence the words “either party” with “the Hedging Party” and (4) deleting clause (X) in the final sentence.

(f)            Repurchase Notices.  Issuer shall, on any day on which Issuer effects any repurchase of Shares, provide Dealer with a written notice of such repurchase (a “Repurchase Notice”) on such day if, following such repurchase, the Warrant Equity Percentage (as defined below) is greater by 0.5% or more than the Warrant Equity Percentage set forth in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater by 0.5% or more than the Warrant Equity Percentage as of September 4, 2013 (calculated as if this Transaction had been entered into as of such date)).  The “Warrant Equity Percentage” as of any day is the fraction, expressed as a percentage, of the numerator of which is the sum of (x) the Number of Warrants and (y) the number of warrants included in any other warrant transaction substantially similar hereto except as to the “Trade Date,” “Effective Date” and “Number of Warrants” (an “Other Warrant Transaction”) between Dealer as buyer and Issuer as seller, and the denominator of which is the number of Shares outstanding on such day.  Issuer agrees to indemnify and hold harmless Dealer, its affiliates and their respective directors, officers, employees, agents and controlling persons (Dealer and each such person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable securities laws, including without limitation, Section 16 of the Exchange Act, relating to or arising out of such failure.  If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Issuer shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability.  In addition, Issuer will reimburse any Indemnified Party for all expenses (including reasonable counsel fees and expenses) as they are incurred (after notice to Issuer) in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Issuer.  This indemnity shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and delegation of the Transaction made pursuant to this Confirmation or the Agreement shall inure to the benefit of any permitted assignee of Dealer.

(g)           Transfer or Assignment.  Dealer may transfer or assign its rights and obligations hereunder and under the Agreement, in whole or in part, at any time to any person or entity whatsoever without the consent of Issuer; provided that, in Issuer’s reasonable determination, Issuer will not be required, as a result of such transfer or assignment, to pay the transferee or assignee an amount under Section 2(d)(i)(4) of the Agreement greater than the amount, if any, that Issuer would have been required to pay to Dealer in the absence of such transfer or assignment.  At any time at which any Ownership Limitation or a Hedging Disruption exists, if Dealer, in its discretion after first using commercially reasonable efforts, is unable to effect a transfer or assignment to a third party on pricing terms and within a time period reasonably acceptable to Dealer such that an Ownership Limitation or a Hedging Disruption, as the case may be, no longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of the Transaction, such that such Ownership Limitation or a Hedging Disruption, as the case may be, no longer exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment or delivery shall be made pursuant to Section 6 of the Agreement or Section 8(a) of this Confirmation as if (i) an

17

Early Termination Date had been designated in respect of a Transaction having terms identical to the Terminated Portion of the Transaction, (ii) Issuer shall be the sole Affected Party with respect to such partial termination and (iii) such portion of the Transaction shall be the only Terminated Transaction.

(h)           Limit on Beneficial Ownership.  Notwithstanding anything to the contrary in the Agreement or this Confirmation, in no event shall Dealer be entitled to receive, or shall be deemed to receive, any Shares in connection with this Transaction if, immediately upon giving effect to such receipt of such Shares, (i) Dealer’s Beneficial Ownership would be equal to or greater than 9.0% of the outstanding Shares, (ii) Dealer, or any “affiliate” or “associate” of Dealer, would own in excess of 13% of the outstanding Shares for purposes of Section 203 of the Delaware General Corporation Law or (iii) Dealer, Dealer Group (as defined below) or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a “Dealer Person”) under any federal, state or local laws, regulations or regulatory orders applicable to ownership of Shares (“Applicable Laws”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership in excess of a number of Shares equal to (x) the number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person under Applicable Laws and with respect to which such requirements have not been met or the relevant approval has not been received or that would give rise to any consequences under the constitutive documents of Issuer or any contract or agreement to which Issuer is a party, in each case minus (y) 1% of the number of Shares outstanding on the date of determination (each of clause (i), (ii) and (iii) above, an “Ownership Limitation”). If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of an Ownership Limitation, Dealer’s right to receive such delivery shall not be extinguished and Issuer shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Dealer gives notice to Issuer that such delivery would not result in any of such Ownership Limitations being breached.  “Dealer’s Beneficial Ownership” means the “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and the rules promulgated thereunder (collectively, “Section 13”)) of Shares, without duplication, by Dealer, together with any of its affiliates or other person subject to aggregation with Dealer under Section 13 for purposes of “beneficial ownership”, or by any “group” (within the meaning of Section 13) of which Dealer is or may be deemed to be a part (Dealer and any such affiliates, persons and groups, collectively, “Dealer Group”) (or, to the extent that, as a result of a change in law, regulation or interpretation after the date hereof, the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such number).  Notwithstanding anything in the Agreement or this Confirmation to the contrary, Dealer shall not become the record or beneficial owner, or otherwise have any rights as a holder, of any Shares that Dealer is not entitled to receive at any time pursuant to this Section 8(h), until such time as such Shares are delivered pursuant to this Section 8(h).

(i)            Limitation On Delivery of Shares.  Notwithstanding anything herein or in the Agreement to the contrary, in no event shall Issuer be required to deliver Shares in connection with the Transaction in excess of two times the Number of Warrants (the “Capped Number”). Notwithstanding anything to the contrary in the Agreement, this Confirmation or the Equity Definitions, in no event shall the Capped Number be subject to adjustment, to the extent that such adjustment would cause the Capped Number to exceed the number of Available Shares, unless such adjustment results from actions of Issuer or events within Issuer’s control.  Issuer represents and warrants to Dealer (which representation and warranty shall be deemed to be repeated on each day that the Transaction is outstanding) that the Capped Number is equal to or less than the number of authorized but unissued Shares of the Issuer that are not reserved for future issuance in connection with transactions in the Shares (other than the Transaction) on the date of the determination of the Capped Number (such Shares, the “Available Shares”).  In the event Issuer shall not have delivered the full number of Shares otherwise deliverable as a result of this Section 8(i) (the resulting deficit, the “Deficit Shares”), Issuer shall be continually obligated to deliver, from time to time until the full number of Deficit Shares have been delivered pursuant to this paragraph, Shares when, and to the extent, that (i) Shares are repurchased, acquired or otherwise received by Issuer or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (ii) authorized and unissued Shares reserved for issuance in respect of other transactions prior to the Trade Date become no longer so reserved or (iii) Issuer additionally authorizes any unissued Shares that are not reserved for other transactions.  Issuer shall immediately notify Dealer of the occurrence of any of the foregoing events (including the number of Shares subject to clause (i), (ii) or (iii) and the corresponding number of Shares to be delivered) and promptly deliver such Shares thereafter.  Issuer shall not, until Issuer’s obligations under the Transaction have been satisfied in full, use any Shares that become available for potential delivery to Dealer as a result of any of the foregoing events for the settlement or satisfaction of any transaction or obligation other than the Transaction or the “Transaction” under any Other Warrant Transaction or reserve any such Shares for future

18

issuance for any purpose other than to satisfy Issuer’s obligations to Dealer under the Transaction or the “Transaction” under any Other Warrant Transaction.

Notwithstanding anything to the contrary herein or in the Definitions or the Agreement, any Payment Obligation shall, for all purposes, be calculated without regard to the provisions set forth under this Section 8(i); provided that the number of Shares deliverable pursuant to Section 8(a) above (if applicable) shall not exceed the applicable Capped Number.

(j)            Right to Extend.  Dealer may postpone any Exercise Date or Settlement 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 Number of Shares to be Delivered with respect to one or more Components), if Dealer determines, in its reasonable discretion, that such extension is reasonably necessary or appropriate to (i) preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions in the cash market, the stock loan market or any other relevant market or (ii) 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.

(k)           No Netting and Set-Off.  Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable law or otherwise.

(l)            Status of Claims in Bankruptcy.  Dealer acknowledges and agrees that this Confirmation is not intended to convey to it rights with respect to the Transaction that are senior to the claims of common stockholders or Issuer in the event of Issuer’s bankruptcy.  For the avoidance of doubt, the parties agree that the preceding sentence shall not apply at any time other than during Issuer’s bankruptcy.

(m)          No Collateral.  Notwithstanding any provision of this Confirmation, the Agreement, the Equity Definitions or any other agreement between the parties to the contrary, the obligations of Issuer under the Transaction are not secured by any collateral.

(n)           Disclosure.  Effective from the date of commencement of discussions concerning the Transaction, Issuer 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 Issuer relating to such tax treatment and tax structure.

(o)           Method of Delivery.  Whenever delivery of funds or other assets is required hereunder by or to Issuer, such delivery shall be effected through MS&CO.  In addition, all notices, demands and communications of any kind relating to the Transaction between Dealer and Issuer shall be transmitted exclusively through MS&CO.

(p)           Effectiveness.  If, prior to the Effective Date, Dealer reasonably determines that it is advisable to cancel the Transaction because of concerns that Dealer’s related hedging activities could be viewed as not complying with applicable securities laws, rules or regulations, the Transaction shall be cancelled and shall not become effective, and neither party shall have any obligation to the other party in respect of the Transaction.

(q)           Severability; Illegality.  Notwithstanding anything to the contrary in the Agreement, if compliance by either party with any provision of the Transaction would be unenforceable or illegal, (a) the parties shall negotiate in good faith to resolve such unenforceability or illegality in a manner that preserves the economic benefits of the transactions contemplated hereby and (b) the other provisions of the Transaction shall not be invalidated, but shall remain in full force and effect.

(r)            Agreements and Acknowledgments Regarding Hedging.  Issuer understands, acknowledges and agrees that: (A) at any time on and prior to the final 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 VWAP Price; 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 VWAP Price, each in a manner that may be adverse to Issuer.

19

(s)            Wall Street Transparency and Accountability Act of 2010.  The parties hereby agree that none of (v) Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), (w) any similar legal certainty provision in any legislation enacted, or rule or regulation promulgated, on or after the Trade Date, (x) the enactment of WSTAA or any regulation under the WSTAA, (y) any requirement under WSTAA nor (z) an amendment made by WSTAA, shall limit or otherwise impair either party’s rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, Loss of Stock Borrow, Increased Cost of Stock Borrow, an Excess Ownership Position or Illegality (as defined in the Agreement)).

(t)            Certain Tax Considerations.

(i)            Dealer makes the following representations to Issuer: (A) it is a “foreign person” (as that term is used in Section 1.6041-4(a)(4) of the U.S. Treasury Regulations), and (B) it is a “non-U.S. branch of a foreign person” (as that term is used in Section 1.1441-4(a)(3)(ii) of the U.S. Treasury Regulations) for U.S. federal income tax purposes.  Dealer agrees to complete, accurately and in a manner reasonably satisfactory to Issuer, to execute and to deliver to Issuer a valid U.S. Internal Revenue Service Form W-8BEN (or any successor form) and any required attachments thereto (x) upon execution of this Confirmation and thereafter prior to the date on which such form becomes invalid, (y) promptly upon reasonable demand by Issuer and (z) promptly upon learning that any Form W-8BEN (or any successor thereto) previously provided by Dealer has become obsolete, invalid or incorrect.

(ii)           Issuer makes the following representation to Dealer: it is a corporation established under the laws of the State of Delaware and is a “United States person” (as that term is defined in Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended).

(iii)          Issuer agrees to complete, accurately and in a manner reasonably satisfactory to Dealer, to execute and to deliver to Dealer a valid U.S. Internal Revenue Service Form W-9 (or any successor form) and any required attachments thereto (A) upon execution of this Confirmation and thereafter prior to the date on which such form becomes invalid, (B) promptly upon reasonable demand by Dealer and (C) promptly upon learning that any Form W-9 (or any successor thereto) previously provided by Issuer has become obsolete, invalid or incorrect.

(u)           Early Unwind.  In the event the sale by Issuer of the Optional Securities (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers pursuant to the Purchase Agreement for any reason by the close of business in New York on September 10, 2013 (or such later date as agreed upon by the parties, which in no event shall be later than the fifth business day thereafter) (September 10, 2013 or such later date being the “Early Unwind Date”), the Transaction shall automatically terminate (the “Early Unwind”) on the Early Unwind Date and (x) the Transaction and all of the respective rights and obligations of Dealer and Issuer thereunder shall be cancelled and terminated and (y) Issuer shall assume, or reimburse the cost of, derivatives and other hedging activities entered into by Dealer or one or more of its affiliates in connection with hedging the Transaction and the unwind of such hedging activities, and purchase any Shares purchased by Dealer or one or more of its affiliates in connection with hedging the Transaction at the cost at which Dealer or such affiliates purchased such Shares. Following such termination, cancellation and payment, subject to the preceding sentence, 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 either party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date.

(v)           Waiver of Jury Trial.  EACH OF ISSUER AND BUYER HEREBY IRREVOCABLY WAIVES (ON ITS OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS) ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THE TRANSACTION OR THE ACTIONS OF BUYER OR ITS AFFILIATES IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF.
