Upon receipt by the Corporation of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in the case of any such loss, theft or destruction, upon receipt of a bond, indemnity or security reasonably satisfactory to the Corporation, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Corporation shall make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and representing the right to purchase the same aggregate number of Warrant Shares as provided for in such lost, stolen, destroyed or mutilated Warrant.

13

11. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding day that is a Business Day.

12. Adjustments and Other Rights. The Exercise Price and Warrant Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as follows; provided that if more than one subsection of this Section 12 is applicable to a single event, the subsection shall be applied that produces the largest adjustment and no single event shall cause an adjustment under more than one subsection of this Section 12 so as to result in duplication.

(i) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Corporation shall at any time or from time to time (a) declare, order, pay or make a dividend or make a distribution on its Common Stock in shares of Common Stock, (b) split, subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares or (c) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, the number of Warrant Shares issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be proportionately adjusted so that the Warrantholder immediately after such record date or effective date, as the case may be, shall be entitled to purchase the number of shares of Common Stock which such holder would have owned or been entitled to receive in respect of the shares of Common Stock subject to this Warrant after such date had this Warrant been exercised in full immediately prior to such record date or effective date, as the case may be (disregarding whether or not this Warrant had been exercisable by its terms at such time). In the event of such adjustment, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be immediately adjusted to the number obtained by dividing (x) the product of (1) the number of Warrant Shares issuable upon the exercise of this Warrant in full before the adjustment determined pursuant to the immediately preceding sentence (disregarding whether or not this Warrant was exercisable by its terms at such time) and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the dividend, distribution, split, subdivision, combination or reclassification giving rise to such adjustment by (y) the new number of Warrant Shares issuable upon exercise of the Warrant in full determined pursuant to the immediately preceding sentence (disregarding whether or not this Warrant is exercisable by its terms at such time).

(ii) Certain Issuances of Common Shares or Convertible Securities. If the Corporation shall at any time or from time to time issue shares of Common Stock (or

14

rights or warrants or any other securities or rights exercisable or convertible into or exchangeable (collectively, a “conversion”) for shares of Common Stock) (collectively, “convertible securities”) (other than in Permitted Transactions or a transaction to which the adjustments set forth in subsection (i) of this Section 12 are applicable), without consideration or at a consideration per share (or having a conversion price per share) that is less than 100% of the Market Price of Common Stock immediately prior to the date of the agreement on pricing of such shares (or of such convertible securities) (such date of agreement, the “Pricing Date”) other than as a result of the payment, deduction or application of customary discounts, commissions, spreads, fees or other similar amounts as determined by, or agreed to with, the underwriter(s), placement agent(s) or other person(s) performing similar functions in connection with such issuance then, in such event:

(A) the number of Warrant Shares issuable upon the exercise of this Warrant immediately prior to the Pricing Date (the “Initial Number”) shall be increased to the number obtained by multiplying the Initial Number by a fraction (I) the numerator of which shall be the sum of (x) the number of shares of Common Stock outstanding immediately prior to the Pricing Date and (y) the number of additional shares of Common Stock issued (or into which convertible securities may be converted) and (II) the denominator of which shall be the sum of (x) the number of shares of Common Stock outstanding immediately prior to the Pricing Date and (y) the number of shares of Common Stock (rounded to the nearest whole share) which the Aggregate Consideration in respect of such issuance of shares of Common Stock (or convertible securities) would purchase at the Market Price of Common Stock immediately prior to the Pricing Date; and

(B) the Exercise Price payable upon exercise of this Warrant shall be adjusted by multiplying such Exercise Price in effect immediately prior to the Pricing Date by a fraction, the numerator of which shall be the number of shares of Common Stock issuable upon exercise of this Warrant in full immediately prior to the adjustment pursuant to clause (A) above (disregarding whether or not this Warrant was exercisable by its terms at such time), and the denominator of which shall be the number of shares of Common Stock issuable upon exercise of this Warrant in full immediately after the adjustment pursuant to clause (A) above (disregarding whether or not this Warrant is exercisable by its terms at such time).

For purposes of the foregoing, (1) the “Aggregate Consideration” in respect of such issuance of shares of Common Stock (or convertible securities) shall be deemed to be equal to the sum of the net offering price (before deduction of any related expenses payable to third parties, including discounts and commissions) of all such shares of Common Stock and convertible securities, plus the aggregate amount, if any, payable upon conversion of any such convertible securities (assuming conversion in accordance with their terms immediately following their issuance (and further assuming for this

15

purpose that such convertible securities are convertible at such time)); (2) in the case of the issuance of such shares of Common Stock or convertible securities for, in whole or in part, any non-cash property (or in the case of any non-cash property payable upon conversion of any such convertible securities), the consideration represented by such non-cash property shall be deemed to be the Market Price (in the case of securities) and/or Fair Market Value (in all other cases), as applicable, of such non-cash property as of immediately prior to the Pricing Date (before deduction of any related expenses payable to third parties, including discounts and commissions); (3) on any increase in the number of shares of Common Stock deliverable upon conversion of any such issued convertible securities, and/or any decrease in the consideration receivable by the Corporation in respect of any such conversion (each, a “Post-Issuance Adjustment”), then, to the extent that, in respect of the same facts and events, the adjustment provisions set forth in this Section 12 (excluding this clause (3)) do not result in a proportionate increase in the number of Warrant Shares issuable upon the exercise of this Warrant, and/or a proportionate decrease in the Exercise Price payable upon exercise of this Warrant, in each case equal to or greater than the proportionate increase and/or decrease, respectively, in respect of such convertible securities, then the number of Warrant Shares issuable, and the Exercise Price payable, upon exercise of this Warrant, in each case then in effect, shall forthwith be readjusted to such number of Warrant Shares and such Exercise Price as would have been obtained had the Post-Issuance Adjustment been effective in respect of such convertible securities as of immediately prior to the Pricing Date of such convertible securities; (4) if the Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant shall have been adjusted upon the issuance of any convertible securities in accordance with this Section 12, subject to clause (3) above, no further adjustment of the Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant shall be made for the actual issuance of shares of Common Stock upon the actual conversion of such convertible securities in accordance with their terms; and (5) “Permitted Transactions” shall consist of (a) issuances of shares of Common Stock (including upon exercise of options) to directors, advisors, employees or consultants of the Corporation pursuant to a stock option plan, employee stock purchase plan, restricted stock plan, other employee benefit plan or other similar compensatory agreement or arrangement approved by the Board of Directors, (b) issuances of shares of Common Stock in accordance with or pursuant to the Convertible Notes due 2022 or the Existing Warrants and (c) the exercise of this Warrant. Any adjustment made pursuant to this Section 12(ii) shall become effective immediately upon the date of such issuance. For the avoidance of doubt, no increase to the Exercise Price or decrease in the number of Warrant Shares issuable upon exercise of this Warrant shall be made pursuant to this Section 12(ii).

(iii) Distributions. If the Corporation shall fix a record date for the making of a dividend or other distribution (by spin-off or otherwise) on shares of Common Stock, whether in cash, Equity Interests of the Corporation, other securities of the Corporation, evidences of indebtedness of the Corporation or any other Person or any other property

16

(including Equity Interests, other securities or evidences of indebtedness of a subsidiary), or any combination thereof, excluding (A) dividends or distributions subject to adjustment pursuant to Section 12(i) or (B) dividends or distributions of rights in connection with the adoption of a stockholder rights plan in customary form (including with respect to the receipt of such rights in respect of shares of Common Stock (including Warrant Shares) issued subsequent to the initial dividend or distribution of such rights), then in each such case, the number of Warrant Shares issuable upon exercise of this Warrant in full (disregarding whether or not this Warrant had been exercisable by its terms at such time) shall be increased by multiplying such number of Warrant Shares by a fraction, the numerator of which is the Market Price per share of Common Stock on such record date and the denominator of which is the Market Price per share of Common Stock on such record date less the Fair Market Value of the cash and/or any other property, as applicable, to be so paid or distributed in such dividend or distribution in respect of one share of Common Stock (in each case as of the record date of such dividend or distribution); such adjustment shall take effect on the record date for such dividend or distribution. In the event of such adjustment, the Exercise Price shall immediately be decreased by multiplying such Exercise Price by a fraction, the numerator of which is the number of Warrant Shares issuable upon the exercise of this Warrant in full immediately prior to such adjustment (disregarding whether or not this Warrant was exercisable by its terms at such time), and the denominator of which is the new number of Warrant Shares issuable upon exercise of this Warrant determined in accordance with the immediately preceding sentence. Notwithstanding the foregoing, in the event that the Fair Market Value of the cash and/or any other property, as applicable, to be so paid or distributed in such dividend or distribution in respect of one share of Common Stock (in each case as of the record date of such dividend or distribution) is equal to or greater than the Market Price per share of Common Stock on such record date, then proper provision shall be made such that upon exercise of this Warrant, the Warrantholder shall receive, in addition to the applicable Warrant Shares, the amount and kind of such cash and/or any other property such Warrantholder would have received had such Warrantholder exercised this Warrant immediately prior to such record date (disregarding whether or not this Warrant had been exercisable by its terms at such time). For purposes of the foregoing, in the event that such dividend or distribution in question is ultimately not so made, the Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant then in effect shall be readjusted, effective as of the date when the Board of Directors determines not to make such dividend or distribution, to the Exercise Price that would then be in effect and the number of Warrant Shares that would then be issuable upon exercise of this Warrant if such record date had not been fixed. For the avoidance of doubt, no increase to the Exercise Price or decrease in the number of Warrant Shares issuable upon exercise of this Warrant shall be made pursuant to this Section 12(iii).

Notwithstanding the foregoing provisions of this Section 12(iii), in the event that all or any portion of any such dividend or other distribution is in Other Voting Securities,

17

then, with respect to such dividend or distribution (or such portion thereof that is in Other Voting Securities, as applicable), the Warrantholder shall have the option, exercisable in writing delivered to the Corporation within seven (7) Business Days of such Warrantholder’s receipt of the Corporation’s notice pursuant to Section 12(x) relating to such dividend or other distribution, to elect (1) for the foregoing adjustments set forth in this Section 12(iii) to apply with respect to such dividend or distribution (or such portion thereof that is in Other Voting Securities, as applicable) or (2) in lieu of the foregoing adjustments set forth in this Section 12(iii) with respect to such dividend or distribution (or such portion thereof that is in Other Voting Securities, as applicable), but, for all purposes of this clause (2), after giving effect to the foregoing adjustments set forth in this Section 12(iii) with respect to any portion of such dividend or distribution that is in securities, cash and/or any other property, in each case other than Other Voting Securities, for its right to receive Warrant Shares upon exercise of this Warrant to be converted, effective as of the record date of such dividend or distribution, into the right to exercise this Warrant to acquire such Warrant Shares plus the Other Voting Securities that such Warrant Shares would have been entitled to receive upon consummation of such dividend or distribution, assuming the exercise in full of this Warrant immediately prior to such record date (disregarding whether or not this Warrant was exercisable by its terms at such time); provided that for purposes of this clause (2), (x) the number and type of Other Voting Securities so deliverable upon any exercise of this Warrant shall be adjusted to take into account any stock or security dividends, splits, reverse splits, spin-offs, split-ups, mergers, reclassifications, reorganizations, recapitalizations, combinations or exchanges of securities and the like from and after the consummation of such dividend or distribution in question and at or prior to such exercise of this Warrant and (y) with respect to any such Other Voting Securities that are described in clause (ii) of the definition of Other Voting Securities, the terms of such Other Voting Securities, as issued upon exercise of this Warrant, shall take into account any anti-dilution or other adjustments that would have been applicable to such Other Voting Securities had such Other Voting Securities been outstanding from and after the consummation of such dividend or distribution in question. In the event that such dividend or distribution in question (or such portion thereof that is in Other Voting Securities, as applicable) is ultimately not so made, this Warrant shall be readjusted, effective as of the date when the Board of Directors determines not to make such dividend or distribution (or such portion thereof that is in Other Voting Securities, as applicable), as though the record date thereof had not been fixed.

(iv) Repurchases. If the Corporation or any subsidiary thereof shall at any time or from time to time effect Repurchases, the Exercise Price then in effect and the number of Warrant Shares issuable upon the exercise of this Warrant shall be immediately adjusted, in each case in accordance with the foregoing provisions of this Section 12, as if, in lieu of such Repurchases, the Corporation had (A) first, declared and paid a dividend, in cash, on shares of Common Stock in an aggregate amount equal to the Assumed Payment Amount, with a record date as of the trading day immediately

18

preceding the first public disclosure of the Corporation’s (or such subsidiary’s) intent to effect such Repurchase, and (B) second, effected a reverse-split of Common Stock, in the proportion required to reduce the number of shares of Common Stock outstanding from (1) the number of such shares outstanding immediately prior to the first purchase of Equity Interests comprising such Repurchases to (2) the number of such shares outstanding immediately following the last purchase of Equity Interests comprising such Repurchases (in the case of this clause (B), with such adjustments as are appropriate to exclude the effect of any issuances of Equity Interests, and any dividends, distributions, splits, subdivisions, reclassifications and combinations subject to adjustment pursuant to Section 12(i), in each case from and after the first purchase of Equity Interests comprising such Repurchases and at or prior to the last purchase of Equity Interests comprising such Repurchases). For the avoidance of doubt, no increase to the Exercise Price or decrease in the number of Warrant Shares issuable upon exercise of this Warrant shall be made pursuant to this Section 12(iv). For purposes of the foregoing, the “Assumed Payment Amount” with respect to any Repurchases shall mean the aggregate Market Price (in the case of securities) and/or Fair Market Value (in the case of cash and/or any other property), as applicable, as of such Repurchases, of the aggregate consideration paid to effect such Repurchases.

(v) Business Combination Transactions. In case of any Business Combination or reclassification of Common Stock (other than a reclassification of Common Stock subject to adjustment pursuant to Section 12(i)), notwithstanding anything to the contrary contained herein, (a) the Corporation shall notify the Warrantholder in writing of such Business Combination or reclassification as promptly as practicable (and in any event no later than ten (10) Business Days prior to the effectiveness thereof) and (b) the Warrantholder’s right to receive Warrant Shares upon exercise of this Warrant shall be converted, effective upon the occurrence of such Business Combination or reclassification, into the right to exercise this Warrant to acquire the number of shares of stock or other securities or property (including cash) that the Common Stock issuable (at the time of such Business Combination or reclassification) upon exercise of this Warrant immediately prior to such Business Combination or reclassification would have been entitled to receive upon consummation of such Business Combination or reclassification. In determining the kind and amount of stock, securities or the property receivable upon exercise of this Warrant upon and following adjustment pursuant to this paragraph, if the holders of Common Stock have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination, then the Warrantholder shall have the right to make the same election upon exercise of this Warrant with respect to the number of shares of stock or other securities or property which the Warrantholder shall receive upon exercise of this Warrant. The Corporation, or the Person or Persons formed by the applicable Business Combination or reclassification, or that acquire(s) the applicable shares of Common Stock, as the case may be, shall make lawful provisions to establish such rights and to provide for such adjustments that, for events from and after such Business Combination or reclassification, shall be as nearly equivalent as possible to

19

the rights and adjustments provided for herein, and the Corporation shall not be a party to or permit any such Business Combination or reclassification to occur unless such provisions are made as a part of the terms thereof.

(vi) Top-Up Adjustment. If the Corporation shall at any time or from time to time prior to the Expiration Time issue shares of Common Stock to (A) any holder of the Convertible Notes due 2022 upon the conversion of the Convertible Notes due 2022 (net of any shares of Common Stock delivered to the Corporation upon the exercise of the Existing Call Options in connection with such conversion of the Convertible Notes due 2022) or (B) any holder of the Existing Warrants upon exercise of the Existing Warrants (such net shares of Common Stock issued at such time to such holders, the “New Shares” and such issuance, a “Top-Up Issuance”), then the Corporation shall deliver notice of such issuance to the Warrantholder no later than five (5) Business Days after such issuance and the number of Warrant Shares issuable upon the exercise of this Warrant shall, subject to and unless otherwise provided in Section 3(iii), be increased by an amount equal to the Top-Up Number. In the event that the Corporation (1) refinances the Convertible Notes due 2022 with other notes convertible into Common Stock (the “Refinancing Convertible Notes”) and/or (2) replaces the Existing Warrants with other warrants issued in connection with the issuance of such Refinancing Convertible Notes (the “Replacement Warrants”), the top-up adjustment set forth in this Section 12(vi) shall apply, mutatis mutandis, with respect to any new shares of Common Stock issued by the Corporation upon the conversion of such Refinancing Convertible Notes or upon the exercise of such Replacement Warrants, with the “New Shares” in that circumstance being the number of new shares of Common Stock issued upon the conversion of such Refinancing Convertible Notes (net of any shares of Common Stock delivered to the Corporation in respect of any call options or other hedging arrangement put in place by the Corporation in connection with such Refinancing Convertible Notes (“Replacement Hedging Arrangement”)) or upon the exercise of the Replacement Warrants, as applicable.

For the avoidance of doubt, for purposes of determining the number of “New Shares” issued by the Corporation pursuant to the Convertible Notes due 2022 (or any Refinancing Convertible Notes), the Corporation shall not be deemed to be issuing “New Shares” to the extent the Corporation obtains an equivalent number of shares of Common Stock upon exercise of the Existing Call Options (or any Replacement Hedging Arrangement) and delivers such shares of Common Stock to the holders of the Convertible Notes due 2022 (or the holders of Refinancing Convertible Notes, as applicable) upon the conversion thereof; provided, however, that, for the avoidance of doubt, this exclusion shall not apply to issuances of shares of Common Stock by the Corporation the proceeds of which are used to finance the payment in cash of the strike price of the Existing Call Options (or pursuant to any Replacement Hedging Arrangement, as applicable).

20

(vii) Rounding of Calculations; Minimum Adjustments. All calculations under this Section 12 shall be made to the nearest one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be. Any provision of this Section 12 to the contrary notwithstanding, no adjustment in the Exercise Price or the number of Warrant Shares into which this Warrant is exercisable shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or 1/10th of a share of Common Stock, or more.

(viii) Timing of Issuance of Additional Securities Upon Certain Adjustments. In any case in which (a) the provisions of this Section 12 shall require that an adjustment (the “Subject Adjustment”) shall become effective immediately after a record date (the “Subject Record Date”) for an event and (b) the Warrantholder exercises this Warrant after the Subject Record Date and before the consummation of such event, the Corporation may defer until the consummation of such event (i) issuing to such Warrantholder the incrementally additional shares of Common Stock or other property issuable upon such exercise by reason of the Subject Adjustment and (ii) paying to such Warrantholder any amount of cash in lieu of a fractional share of Common Stock; provided, however, that the Corporation upon request shall promptly deliver to such Warrantholder a due bill or other appropriate instrument evidencing such Warrantholder’s right to receive such additional shares (or other property, as applicable), and such cash, upon the consummation of such event.

(ix) Statement Regarding Adjustments. Whenever the Exercise Price or the Warrant Shares into which this Warrant is exercisable shall be adjusted as provided in Section 12, the Corporation shall forthwith prepare a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price that shall be in effect and the Warrant Shares into which this Warrant shall be exercisable after such adjustment, and cause a copy of such statement to be delivered to the Warrantholder as promptly as practicable.

(x) Notice of Adjustment Event. In the event that the Corporation shall propose to take any action of the type described in this Section 12 (but only if the action of the type described in this Section 12 would result in an adjustment in the Exercise Price or the Warrant Shares into which this Warrant is exercisable or a change in the type of securities or property to be delivered upon exercise of this Warrant), the Corporation shall provide written notice to the Warrantholder, which notice shall specify the record date, if any, with respect to any such action and the approximate date on which such action is to take place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable upon

21

exercise of this Warrant. In the case of any action which would require the fixing of a record date, such notice shall be given at least ten (10) days prior to the date so fixed. In case of all other action, such notice shall be given at least ten (10) days prior to the taking of such proposed action unless the Corporation reasonably determines in good faith that, given the nature of such action, the provision of such notice at least ten (10) days in advance is not reasonably practicable from a timing perspective, in which case such notice shall be given as far in advance prior to the taking of such proposed action as is reasonably practicable from a timing perspective.

(xi) Adjustment Rules. Any adjustments pursuant to this Section 12 shall be made successively whenever an event referred to herein shall occur. If an adjustment in the Exercise Price made hereunder would reduce the Exercise Price to an amount below par value of the Common Stock, then such adjustment in the Exercise Price made hereunder shall reduce the Exercise Price to the par value of the Common Stock.

(xii) No Impairment. The Corporation shall not, by amendment of its certificate of incorporation, bylaws or any other organizational document, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but shall at all times in good faith assist in the carrying out of all the provisions of this Warrant. In furtherance and not in limitation of the foregoing, the Corporation shall not take or permit to be taken any action which would entitle the Warrantholder to an adjustment under this Section 12 if the total number of shares of Common Stock issuable after such action upon exercise of this Warrant in full (disregarding whether or not this Warrant is exercisable by its terms at such time), together with all shares of Common Stock then outstanding and all shares of Common Stock then issuable upon the exercise in full of any and all outstanding Equity Interests (disregarding whether or not any such Equity Interests are exercisable by their terms at such time) would exceed the total number of shares of Common Stock then authorized by its certificate of incorporation.

(xiii) Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 12, the Corporation shall take any and all action which may be necessary, including obtaining regulatory or other governmental, The NASDAQ Global Select Market or other applicable securities exchange, corporate or stockholder approvals or exemptions, in order that the Corporation may thereafter validly and legally issue as fully paid and nonassessable all shares of Common Stock, or all other securities or other property, that the Warrantholder is entitled to receive upon exercise of this Warrant pursuant to this Section 12.

13. Mandatory Exercise Upon Change of Control. Notwithstanding anything to the contrary contained herein, in the event of the consummation prior to the Expiration

22

Time of a Business Combination where all outstanding shares of Common Stock are exchanged solely for cash consideration (other than, for the avoidance of doubt, shares held as treasury stock, shares with respect to which appraisal or dissenter rights apply and shares that are customarily cancelled in a Business Combination of such type) (“Qualifying Business Combination”), the Corporation shall have the right (a) if the consideration per share of Common Stock to be received by the holders of Common Stock in such Qualifying Business Combination is greater than the Exercise Price, to cause the Warrantholder to exercise this Warrant with respect to all Warrant Shares as of the consummation of such Qualifying Business Combination and (b) if the consideration per share of Common Stock to be received by the holders of Common Stock in such Qualifying Business Combination is less than or equal to the Exercise Price, to cause this Warrant to be automatically and immediately canceled and terminated as of the consummation of such Qualifying Business Combination with respect to all Warrant Shares; provided that the Corporation must give written notice to the Warrantholder at least ten (10) Business Days prior to the date of consummation of such Qualifying Business Combination, which notice shall specify the expected date on which such Qualifying Business Combination is to take place and set forth the facts with respect thereto as shall be reasonably necessary to indicate the amount of cash deliverable upon exercise of this Warrant and to each outstanding share of Common Stock; provided, further that the Corporation may only cause this Warrant to be exercised or cancelled, as applicable, concurrently with the consummation of such Qualifying Business Combination and the Warrantholder shall be entitled to receive the cash consideration as determined pursuant to Section 12(v). If the Warrantholder is required to exercise this Warrant pursuant to this Section 13, the Warrantholder shall notify the Corporation within five (5) Business Days after receiving the Corporation’s written notice described above in this Section 13 whether it is electing to exercise this Warrant through a Cash Exercise or a Cashless Exercise. If the Warrantholder (i) does not provide such notice within five (5) Business Days after receiving the Corporation’s written notice described above in this Section 13, or (ii) elects a Cash Exercise but does not pay the applicable Exercise Price for the Warrant Shares thereby purchased to the Corporation upon the consummation of such Qualifying Business Combination then, in either such case, the Corporation shall effect the exercise of this Warrant through a Cashless Exercise.

14. Governing Law and Jurisdiction. This Warrant shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. In addition, each of the parties (a) submits to the personal jurisdiction of the Delaware Court of Chancery in and for New Castle County, or in the event (but only in the event) that such Delaware Court of Chancery does not have subject matter jurisdiction over such dispute, the United States District Court for the District of Delaware, or in the event (but only in the event) that such United States District Court also does not have

23

jurisdiction over such dispute, any Delaware State court sitting in New Castle County, in the event any dispute (whether in contract, tort or otherwise) arises out of this Warrant or the transactions contemplated hereby, (b) irrevocably waives the defense of an inconvenient forum or lack of jurisdiction to the maintenance of any claim, action or proceeding relating to this Warrant or the transactions contemplated hereby and agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court and (c) agrees that it shall not bring any claim, action or proceeding relating to this Warrant or the transactions contemplated hereby in any court other than the Delaware Court of Chancery in and for New Castle County, or in the event (but only in the event) that such Delaware Court of Chancery does not have subject matter jurisdiction over such claim, action or proceeding, the United States District Court for the District of Delaware, or in the event (but only in the event) that such United States District Court also does not have jurisdiction over such claim, action or proceeding, any Delaware State court sitting in New Castle County. Each party agrees that service of process upon such party in any such claim, action or proceeding shall be effective if notice is given in accordance with the provisions of this Warrant.

15. Binding Effect. This Warrant shall be binding upon any successors or assigns of the Corporation.

16. Amendments. This Warrant may be amended and the observance of any term of this Warrant may be waived only with the written consent of the Corporation and the Warrantholder.

17. Notices. Any notice, request, instruction or other document to be given hereunder by any party to the other shall be in writing and shall be deemed to have been duly given (a) if sent by registered or certified mail in the United States, return receipt requested, upon receipt, (b) if sent by nationally recognized overnight air courier, one (1) Business Day after mailing, (c) if sent by email or facsimile transmission, with a copy mailed on the same day in the manner provided in clauses (a) or (b) of this Section 17 when transmitted and receipt is confirmed, or (d) if otherwise personally delivered, when delivered. All notices hereunder shall be delivered as set forth below, or pursuant to such other instructions as may be designated in writing by the party to receive such notice.

24

18. Entire Agreement. This Warrant and the form attached hereto, the Investment Agreement, the other Transaction Documents and the Confidentiality Agreement (as defined in the Investment Agreement) constitute the entire agreement, and supersede all other prior agreements, understandings, representations and warranties, both written and oral, between the parties, with respect to the subject matter hereof.

19. Specific Performance. The parties agree that failure of any party to perform its agreements and covenants hereunder, including a party’s failure to take all

25

actions as are necessary on such party’s part in accordance with the terms and conditions of this Warrant to consummate the transactions contemplated hereby, will cause irreparable injury to the other party, for which monetary damages, even if available, will not be an adequate remedy. It is agreed that the parties shall be entitled to equitable relief including injunctive relief and specific performance of the terms hereof, without the requirement of posting a bond or other security, and each party hereby consents to the issuance of injunctive relief by any court of competent jurisdiction to compel performance of a party’s obligations and to the granting by any court of the remedy of specific performance of such party’s obligations hereunder, this being in addition to any other remedies to which the parties are entitled at law or equity.
