Each exercise of a Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which each of the requirements for exercise of such Warrant specified in Section 3.2(c) has been duly satisfied (the “Exercise Date”). At such time, subject to Section 5.1(f)(iv), shares of Common Stock in book-entry form or the certificates for the shares of Common Stock issuable upon such exercise as provided in Section 3.2(e) shall be deemed to have been issued and, for all purposes of this Agreement, the Recipient shall, as between such Person and the Company, be deemed to be and entitled to all rights of the holder or record of such Common Stock.

3.3 Application of Funds upon Exercise of Warrants. Any funds delivered to the Warrant Agent upon exercise of any Warrant(s) shall be held by the Warrant Agent in trust for the Company. The Warrant Agent shall promptly deliver and pay to or upon the written order of the Company all funds received by it upon the exercise of any Warrants by bank wire transfer to an account designated by the Company or as the Warrant Agent otherwise may be directed in writing by the Company.

3.4 Payment of Taxes. The Company shall pay any and all taxes (other than income taxes) that may be payable in respect of the issue or delivery of shares of Common Stock on exercise of Warrants pursuant hereto. The Company shall not be required, however, to pay any tax or other charge imposed in respect of any transfer involved in the issue and delivery of shares of Common Stock in book-entry form or any certificates for shares of Common Stock or payment of cash or other property to any Recipient other than the Holder of the Warrant Certificate evidencing the exercised Warrant, and in case of such transfer or payment, the Warrant Agent and the Company shall not be required to issue or deliver any shares of Common Stock in book-entry form or any certificate or pay any cash until (a) such tax or charge has been paid or an amount sufficient for the payment thereof has been delivered to the Warrant Agent or the Company or (b) it has been established to the Company’s satisfaction that any such tax or other charge that is or may become due has been paid.

3.5 Cancellation of Warrant Certificates. Any Definitive Warrant Certificate surrendered for exercise shall, if surrendered to the Company, be delivered to the Warrant Agent. All Warrant Certificates surrendered or delivered to or received by the Warrant Agent for cancellation pursuant to this Section 3.5 or Section 2.4(e) or Section 2.4(k) shall be promptly cancelled by the Warrant Agent and shall not be reissued by the Company. The Warrant Agent shall destroy any such cancelled Warrant Certificates and deliver its certificate of destruction to the Company, unless the Company shall otherwise direct.

3.6 Shares Issuable. The number of shares of Common Stock “obtainable upon exercise” of Warrants at any time shall be the number of shares of Common Stock into which such Warrants are then exercisable. The number of shares of Common Stock “into which each Warrant is exercisable” shall be one share, subject to adjustment as provided in Section 5.1.

3.7 Maximum Percentage. A Holder of a Warrant will have notified the Company and the Warrant Agent in writing by submitting the notice form included as Exhibit B attached hereto to the Company and the Warrant Agent prior to the Original Issue Date in the event it elects to be subject to the provisions contained in this Section 3.7; however, no Holder of a Warrant shall be subject to this Section 3.7 unless he, she or it makes such election. If the election is made by a

13

Holder, the Warrant Agent shall not effect the exercise of the Holder’s Warrant, and such Holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such Person (together with such Person’s Affiliates and any Person who is a member of a group (as defined in Rule 13d-5 under the Exchange Act) with such Person (such Person a “Group Member”) relating to the equity securities of the Company), to the Warrant Agent’s knowledge based solely on the information certified to the Warrant Agent in the Exercise Form, would beneficially own in excess of 9.9% (the “Maximum Percentage”) of the shares of Common Stock outstanding. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person, its Affiliates and its Group Members shall include the number of shares of Common Stock issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such Person and its Affiliates and Group Members, if the shares underlying the Warrant would exceed the Maximum Percentage and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its Affiliates and Group Members (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. Solely the Warrant Agent shall determine the extent to which the Warrant is exercisable in accordance with this Section 3.7, and neither the Company nor any transfer agent of the Company shall have any obligation to verify or confirm the accuracy of such determination. For purposes of making the foregoing determination, the Company shall, within two (2) Business Days, confirm orally and in writing to the Warrant Agent the number of shares of Common Stock then outstanding. For any reason at any time, upon the written request of the Holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. By written notice to the Company and the Warrant Agent, the Holder of a Warrant may from time to time (i) increase or decrease the Maximum Percentage applicable to such Holder to any other percentage specified in such notice or (ii) revoke its election pursuant to this Section 3.7; provided, however, that any such increase, decrease or revocation shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company and the Warrant Agent.

Unless Section 5.1(h) applies, if, on or prior to the Expiration Date, the Company (or any other Person controlling the Company) shall propose a voluntary or involuntary dissolution, liquidation or winding up (collectively, a “Winding Up”; provided that a Winding Up shall not be effected pursuant to a Transaction) of the affairs of the Company, the Company shall give written notice thereof to the Warrant Agent and all Holders in the manner provided in Section 11.1(b) prior to the date on which such transaction is expected to become effective or, if earlier, the record date for such transaction. Such notice shall also specify the date as of which the holders of record of the shares of Common Stock shall be entitled to exchange their shares for securities, money or other property deliverable upon such dissolution, liquidation or winding up, as the case may be, on which date each Holder of Warrant Certificates shall receive the securities, money or other property which such Holder would have been entitled to receive had such Holder been the holder of record of the shares of Common Stock into which the Warrants were exercisable immediately prior to such dissolution, liquidation or winding up (net of the then applicable Exercise Price) and the rights to exercise the Warrants shall terminate.

14

Unless Section 5.1(h) applies, in case of any Winding Up of the Company, the Company shall deposit with the Warrant Agent any funds or other property which the Holders are entitled to receive pursuant to the above paragraph, together with a Company Order as to the distribution thereof. After receipt of such deposit from the Company and after receipt of surrendered Warrant Certificates evidencing Warrants, the Warrant Agent shall make payment in appropriate amount to such Person or Persons as it may be directed in writing by the Holder surrendering such Warrant Certificate. The Warrant Agent shall not be required to pay interest on any money deposited pursuant to the provisions of this Section 4 except such as it shall agree with the Company to pay thereon. Any moneys, securities or other property which at any time shall be deposited by the Company or on its behalf with the Warrant Agent pursuant to this Section 4 shall be, and are hereby, assigned, transferred and set over to the Warrant Agent in trust for the purpose for which such moneys, securities or other property shall have been deposited; provided that moneys, securities or other property need not be segregated from other funds, securities or other property held by the Warrant Agent except to the extent required by law.

5.1 Adjustments. In order to prevent dilution of the rights granted under the Warrants and to grant the Holders certain additional rights, the Exercise Price shall be subject to adjustment from time to time only as specifically provided in this Section 5.1 and the number of shares of Common Stock obtainable upon exercise of Warrants shall be subject to adjustment from time to time only as specifically provided in this Section 5.1.

(a) Subdivisions and Combinations. In the event the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, effect a subdivision (by any stock split, subdivision or otherwise) of the outstanding shares of Common Stock into a greater number of shares of Common Stock (other than (x) a subdivision upon a Transaction to which Section 5.1(h) applies or (y) a stock split effected by means of a stock dividend or distribution to which Section 5.1(b) applies), then and in each such event the Exercise Price in effect at the opening of business on the day after the date upon which such subdivision becomes effective shall be proportionately decreased. Conversely, if the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, effect a combination (by any reverse stock split, combination or otherwise) of the outstanding shares of Common Stock into a smaller number of shares of Common Stock (other than a combination upon a Transaction to which Section 5.1(h) applies), then and in each such event the Exercise Price in effect at the opening of business on the day after the date upon which such combination becomes effective shall be proportionately increased. Any adjustment under this Section 5.1(a) shall become effective immediately after the opening of business on the day after the date upon which the subdivision or combination becomes effective.

15

(b) Stock Dividends. In the event the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, make or issue to the holders of its Common Stock a dividend or distribution payable in, or otherwise make or issue a dividend or other distribution on any class of its capital stock payable in, shares of Common Stock (other than a dividend or distribution upon a Transaction to which Section 5.1(h) applies), then and in each such event the Exercise Price in effect at the opening of business on the day after the date for the determination of the holders of shares of Common Stock entitled to receive such dividend or distribution shall be decreased by multiplying such Exercise Price by a fraction (not to be greater than 1):

(i) the numerator of which shall be the total number of shares of Common Stock issued and outstanding at the close of business on such date for determination; and

(ii) the denominator of which shall be the total number of shares of Common Stock issued and outstanding at the close of business on such date for determination plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

Any adjustment under this Section 5.1(b) shall, subject to Section 5.1(f)(iv), become effective immediately after the opening of business on the day after the date for the determination of the holders of shares of Common Stock entitled to receive such dividend or distribution.

(c) Reclassifications. A reclassification of the Common Stock (other than any such reclassification in connection with a Transaction to which Section 5.1(h) applies) into shares of Common Stock and shares of any other class of stock shall be deemed:

(i) a Spin-Off Dividend by the Company to the holders of its Common Stock of such shares of such other class of stock for the purposes and within the meaning of Section 5.1(d) (and the effective date of such reclassification shall be deemed to be “the date for the determination of the holders of Common Stock entitled to receive such Spin-Off Dividend” for the purposes and within the meaning of Section 5.1(d)); and

(ii) if the outstanding shares of Common Stock shall be changed into a larger or smaller number of shares of Common Stock as a part of such reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding shares of Common Stock for the purposes and within the meaning of Section 5.1(a) (and the effective date of such reclassification shall be deemed to be “the date upon which such subdivision becomes effective” or “the date upon which such combination becomes effective,” as applicable, for the purposes and within the meaning of Section 5.1(a)).

(d) Spin-Off Dividend. In the event the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, make or issue any Spin-Off Dividend, then and in each such event, the Exercise Price in effect immediately prior to the close of business on the date for the determination of the holders of Common Stock entitled to receive such Spin-Off Dividend shall be decreased by multiplying such Exercise Price by a fraction (not to be greater than 1):

16

(i) the numerator of which shall be the Current Market Price per share of Common Stock on such date for determination minus the portion applicable to one share of Common Stock of the Fair Market Value ( as determined in good faith by the Board of Directors, whose determination shall be evidenced by a resolution of the Board of Directors filed with the Warrant Agent) of such Spin-Off Dividend so distributed; and

(ii) the denominator of which shall be such Current Market Price per share of Common Stock.

Any adjustment under this Section 5.1(d) shall, subject to Section 5.1(f)(v) become effective immediately prior to the opening of business on the day after the date for the determination of the holders of Common Stock entitled to receive such Spin-Off Dividend. If the Board of Directors determines the Fair Market Value of any Spin-Off Dividend for purposes of this Section 5.1(d) by reference to the actual or when issued trading market for any securities comprising such Spin-Off Dividend, it must in doing so consider the volume weighted average prices in such market on the same date used in computing the Current Market Price per share of Common Stock.

For purposes of clarity, if a Spin-Off Dividend would have reduced the Exercise Price to an amount below the par value per share of the Common Stock, the Exercise Price will be reduced to the par value per share of the Common Stock.

(e) Special Dividends. In the event the Company shall, at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, pay or make any Special Dividend, then and in each such event, the Exercise Price in effect immediately prior to the close of business on the date for the determination of the holders of Common Stock entitled to receive such Special Dividend shall be decreased (to an amount not less than the lesser of the par value of the Common Stock as of the date hereof and such par value as of such date of determination) by an amount equal to the amount of the cash so distributed to one share of Common Stock.

Any adjustment under this Section 5.1(e) shall, subject to Section 5.1(f)(v), become effective immediately prior to the opening of business on the day after the date for the determination of the holders of Common Stock entitled to receive such Special Dividend.

For purposes of clarity, if a Special Dividend would have reduced the Exercise Price to an amount below the par value per share of the Common Stock, the Exercise Price will be reduced to the par value per share of the Common Stock and any remaining amount of cash of the Special Dividend that would have resulted in a reduction of the Exercise Price below the par value per share of the Common Stock shall be disregarded.

(f) Other Provisions Applicable to Adjustments. The following provisions shall be applicable to the making of adjustments to the Exercise Price and the number of shares of Common Stock into which each Warrant is exercisable under Section 5.1:

(i) Treasury Stock. The dividend or distribution of any issued shares of Common Stock owned or held by or for the account of the Company shall be deemed a dividend or distribution of shares of Common Stock for purposes of Section 5.1(b). The Company shall not make or issue any dividend or distribution on shares of Common Stock held in the treasury of the Company. For the purposes of Section 5.1(b), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company.

17

(ii) When Adjustments Are to be Made. The adjustments required by Section 5.1(a), Section 5.1(b), Section 5.1(c), Section 5.1(d) and Section 5.1(e) shall be made whenever and as often as any specified event requiring an adjustment shall occur, except that no adjustment of the Exercise Price that would otherwise be required shall be made unless and until such adjustment either by itself or with other adjustments not previously made increases or decreases the Exercise Price immediately prior to the making of such adjustment by at least 1%. Any adjustment representing a change of less than such minimum amount (except as aforesaid) shall be carried forward and made as soon as such adjustment, together with other adjustments required by Section 5.1(a), Section 5.1(b), Section 5.1(c), Section 5.1(d) and Section 5.1(e) and not previously made, would result in such minimum adjustment.

(iii) Fractional Interests. In computing adjustments under this Section 5.1, fractional interests in Common Stock shall be taken into account to the nearest one-thousandth of a share.

(iv) Deferral of Issuance Upon Exercise. In any case in which Section 5.1(b) or Section 5.1(d) shall require that a decrease in the Exercise Price be made effective prior to the occurrence of a specified event and any Warrant is exercised after the time at which the adjustment became effective but prior to the occurrence of such specified event and, in connection therewith, Section 5.1(g) shall require a corresponding increase in the number of shares of Common Stock into which each Warrant is exercisable, the Company may elect to defer (but not in any event later than the Expiration Date or the closing date of the applicable Sale Transaction) until the occurrence of such specified event (A) the issuance to the Holder of the Warrant Certificate evidencing such Warrant (or other Person entitled thereto) of, and the registration of such Holder (or other Person) as the record holder of, the Common Stock over and above the Common Stock issuable upon such exercise on the basis of the number of shares of Common Stock obtainable upon exercise of such Warrant immediately prior to such adjustment and to require payment in respect of such number of shares the issuance of which is not deferred on the basis of the Exercise Price in effect immediately prior to such adjustment and (B) the corresponding reduction in the Exercise Price; provided, however, that the Company shall deliver to such Holder or other person a due ▇▇▇▇ or other appropriate instrument that meet any applicable requirements of the principal national securities exchange or other market on which the Common Stock is then traded and evidences the right of such Holder or other Person to receive, and to become the record holder of, such additional shares of Common Stock, upon the occurrence of such specified event requiring such adjustment (without payment of any additional Exercise Price in respect of such additional shares).

18

(v) Deferral of Reduction in Exercise Price. In any case in which Section 5.1(e) shall require that a decrease in the Exercise Price be made effective prior to the occurrence of a specified event and any Warrant is exercised after the time at which the adjustment became effective but prior to the occurrence of such specified event, the Company may elect to defer (but not in any event later than the Expiration Date or the closing date of the applicable Sale Transaction) until the occurrence of such specified event the corresponding reduction in the Exercise Price; provided, however, that the Company shall deliver to the Holder of the Warrant Certificate evidencing such Warrant an appropriate instrument that evidences the right of such Holder to receive from the Company, upon the occurrence of such specified event requiring such adjustment, a cash refund equal to the difference between (x) the Exercise Price paid to the Company on the Exercise Date and (y) the Exercise Price as so reduced as a result of such adjustment pursuant to Section 5.1(e).

(g) Adjustment to Shares Obtainable Upon Exercise. Whenever the Exercise Price is adjusted as provided in this Section 5.1 (other than in Section 5.1(e) in the case of a Special Dividend), the number of shares of Common Stock into which a Warrant is exercisable shall simultaneously be adjusted by multiplying such number of shares of Common Stock into which a Warrant is exercisable immediately prior to such adjustment by a fraction, the numerator of which shall be the Exercise Price immediately prior to such adjustment, and the denominator of which shall be the Exercise Price immediately thereafter.

(h) Changes in Common Stock. In case at any time or from time to time after the Original Issue Date while any Warrants remain outstanding and unexpired in whole or in part, the Company (including any Successor Company) shall be a party to or shall otherwise engage in any transaction or series of related transactions constituting: (1) a consolidation of the Company with, a merger of the Company into, a sale of all or substantially all of the assets of the Company and its Subsidiaries (taken as a whole) to, any other Person, or any similar transaction, in each case, in which the previously outstanding shares of Common Stock shall be entitled to receive (either directly or upon subsequent liquidation), cancelled, reclassified or converted or changed into or exchanged for securities or other property (including cash) or any combination of the foregoing (a “Non-Surviving Transaction”), or (2) any merger of another Person into the Company in which the previously outstanding shares of Common Stock shall be cancelled, reclassified or converted or changed into or exchanged for securities of the Company or other property (including cash) or any combination of the foregoing (a “Surviving Transaction”; any Non-Surviving Transaction or Surviving Transaction being herein called a “Transaction”); then:

(x) if such Transaction constitutes a Sale Cash Only Transaction, then, at the effective time of the consummation of such Sale Cash Only Transaction, (i) any Warrants not exercised prior to the closing of such Sale Cash Only Transaction shall automatically expire, terminate and become void and (ii) the Company shall deliver or cause to be delivered to the Holder of each Warrant Certificate evidencing any unexercised Warrants, cash in an amount, for each Warrant so evidenced, equal to (1) the product of (I) the number of shares of Common Stock into which such Warrant was exercisable immediately prior to such closing and (II) the positive difference, if any, of the Fair Market Value of the Cash Consideration per share of Common Stock in the Transaction and the Exercise Price per share of Common Stock immediately prior to such closing plus (2) if the effective time of

19

the consummation of such Transaction is prior to both (a) the eighteen (18) month anniversary of the Original Issue Date and (b) the effective time of any Sale Securities Only Transaction or Sale Cash and Securities Transaction that occurs after the Original Issue Date, the lesser of (I) the Black-Scholes Value Limit with respect to such Sale Cash Only Transaction and (II) the Black-Scholes Value of each Warrant as of the date of the consummation of the Sale Cash Only Transaction; or

(y) if such Transaction is a Redomestication Transaction, a Non-Sale Transaction, a Sale Cash and Securities Transaction or a Sale Securities Only Transaction:

(i) as a condition to the consummation of such Transaction, the Company shall (or, in the case of any Non-Surviving Transaction, the Company shall cause such other Person to) execute and deliver to the Warrant Agent a written instrument providing that:

(A) if such Transaction constitutes a Redomestication Transaction or a Non-Sale Transaction, any Warrant that remains outstanding in whole or in part, upon the exercise thereof at any time on or after the consummation of such Transaction, shall be exercisable (on such terms and subject to such conditions as shall be as nearly equivalent as may be practicable to the provisions set forth in this Agreement) into, in lieu of the Common Stock issuable upon such exercise prior to such consummation, only the securities or other property (“Substituted Property”) that would have been receivable upon such Transaction by a Qualifying Electing Person holding the number of shares of Common Stock into which such Warrant was exercisable immediately prior to such Transaction and for an aggregate Exercise Price for such Warrant equal to the product of (I) the number of shares of Common Stock into which such Warrant was exercisable immediately prior to such Transaction and (II) the Exercise Price per share of Common Stock immediately prior to such Transaction; provided that if (i) such Non-Sale Transaction would have otherwise been a Sale Cash Only Transaction (but for the percentage beneficial ownership of a Specified Person specified in the definition of such term that caused such Non-Sale Transaction to become such) and (ii) such Warrants would not be entitled to any amount of cash pursuant to Subsection 5.1(h)(x)(ii)(1) or Subsection 5.1(h)(x)(ii)(2), then the Warrants shall automatically expire, terminate and become void upon the closing of such Non-Sale Transaction;

20

(B) if such Transaction constitutes a Sale Securities Only Transaction, any Warrant that remains outstanding in whole or in part, upon the exercise thereof at any time on or after the consummation of such Transaction, shall be exercisable (on such terms and subject to such conditions as shall be as nearly equivalent as may be practicable to the provisions set forth in this Agreement) into, in lieu of the Common Stock issuable upon such exercise prior to such consummation, only the securities (“Substituted Securities”) that would have been receivable upon the consummation of such Transaction by a Qualifying Person holding the number of shares of Common Stock into which such Warrant was exercisable immediately prior to such Transaction and for an aggregate Exercise Price for such Warrant equal to the product of (I) the number of shares of Common Stock into which such Warrant was exercisable immediately prior to such Transaction and (II) the Exercise Price per share of Common Stock immediately prior to such Transaction; or

(C) if such Transaction constitutes a Sale Cash and Securities Transaction, any Warrant that remains outstanding in whole or in part, upon the exercise thereof at any time on or after the consummation of such Transaction, shall be exercisable (on such terms and subject to such conditions as shall be as nearly equivalent as may be practicable to the provisions set forth in this Agreement) into, in lieu of the Common Stock issuable upon such exercise prior to such consummation, only the Substituted Securities that would have been receivable upon such Transaction by a Qualifying Person holding the number of shares of Common Stock into which such Warrant was exercisable immediately prior to such Transaction and for an aggregate Exercise Price for such Warrant equal to the product of (I) the number of shares of Common Stock into which such Warrant was exercisable immediately prior to such Transaction and (II) the Exercise Price per share of Common Stock immediately prior to such time as decreased (to an amount not less than the lesser of the par value of the Common Stock as of the date hereof and such par value as of such date of determination) by an amount equal to the Fair Market Value of the Cash Consideration per share of Common Stock receivable in such Sale Cash and Securities Transaction by a Qualifying Person; provided further, however, that if, as the result of rights of election, the kind or amount of securities, cash and other property receivable upon such Sale Cash and Securities Transaction is not the same for each share of Common Stock held by a Qualifying Person, then, for the purposes of this Section 5.1(h)(y)(i)(C), the kind and amount of securities, cash and other property receivable upon such Sale Cash and Securities Transaction for each share of Common Stock held by a Qualifying Person shall be deemed to be the pro rata kind and amount per share of Common Stock (determined on the basis of all outstanding shares of Common Stock held by Qualifying Persons) actually received by all Qualifying Persons;

21

(ii) except as otherwise specified in Section 5.1(h)(y)(i), the rights and obligations of the Company (or, in the event of a Non-Surviving Transaction, such other Person) and the Holders in respect of Substituted Property (in the case of Section 5.1(h)(y)(i)(A)) or Substituted Securities (in the case of Section 5.1(h)(y)(i)(B) or (C)) shall be substantially unchanged to be as nearly equivalent as may be practicable to the rights and obligations of the Company and Holders in respect of Common Stock hereunder as set forth in Section 3.1 hereof; and

(iii) such written instrument under clause (y)(i) above shall provide for adjustments which, for events subsequent to the effective date of such written instrument, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5. The above provisions of this Section 5.1(h) shall similarly apply to successive Transactions.

For the avoidance of doubt, notwithstanding anything to the contrary contained herein, (i) in no event shall a Holder be entitled to any Fair Market Value on account of the Warrants (using the Black-Scholes Value or otherwise) in any Sale Cash Only Transaction (other than the amount of cash specified in Section 5.1(h)(x)(ii)(1)) if the effective time of the consummation of a Sale Cash Only Transaction is prior to the eighteen (18) month anniversary of the Original Issue Date but after the effective time of any Sale Securities Only Transaction or Sale Cash and Securities Transaction that occurs after the Original Issue Date and (ii) in no event shall a Holder be entitled to any Fair Market Value on account of the Warrants (using the Black-Scholes Value or otherwise) in any Sale Cash and Securities Transaction, Sale Securities Only Transaction, Redomestication Transaction or Non-Sale Transaction (other than the amount of Substituted Property or Substituted Securities, as applicable, specified in Section 5.1(h)(y)(i)(A), (B) or (C), as applicable).

(i) Compliance with Governmental Requirements. Before taking any action that would cause an adjustment reducing the Exercise Price below the then par value of any of the shares of Common Stock into which the Warrants are exercisable, the Company will take any corporate action that may be necessary in order that the Company may validly and legally issue fully paid and non-assessable shares of such Common Stock at such adjusted Exercise Price.

(j) Optional Tax Adjustment. The Company may at its option, at any time during the term of the Warrants, increase the number of shares of Common Stock into which each Warrant is exercisable, or decrease the Exercise Price, in addition to those changes required by Section 5.1(a), Section 5.1(b), Section 5.1(c), Section 5.1(d) or Section 5.1(e) as deemed advisable by the Board of Directors of the Company, in order that any event treated for Federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients.

(k) Warrants Deemed Exercisable. For purposes solely of this Section 5, the number of shares of Common Stock which the holder of any Warrant would have been entitled to receive had such Warrant been exercised in full at any time or into which any Warrant was exercisable at any time shall be determined assuming such Warrant was exercisable in full at such time.

22

(l) Notice of Adjustment. Upon the occurrence of each adjustment of the Exercise Price or the number of shares of Common Stock into which a Warrant is exercisable pursuant to this Section 5.1, the Company at its expense shall promptly:

(i) compute such adjustment in accordance with the terms hereof;

(ii) after such adjustment becomes effective, deliver to all Holders, in accordance with Section 11.1(b) and Section 11.2 (including by means of a current report on Form 8-K), a notice setting forth such adjustment and showing in detail the facts upon which such adjustment (including the kind and amount of securities, cash or other property for which the Warrants shall be exercisable and the Exercise Price) is based; and

(iii) deliver to the Warrant Agent a certificate of the Treasurer of the Company setting forth the Exercise Price and the number of shares of Common Stock into which each Warrant is exercisable after such adjustment and setting forth a brief statement of the facts requiring such adjustment and the computation by which such adjustment was made (including a description of the basis on which the Current Market Price of the Common Stock or the Fair Market Value of any evidences of indebtedness, shares of capital stock, securities, cash or other assets or consideration used in the computation was determined). As provided in Section 10.1, the Warrant Agent shall be entitled to rely on such certificate and shall be under no duty or responsibility with respect to any such certificate, except to exhibit the same from time to time to any Holder desiring an inspection thereof during reasonable business hours.

(m) Statement on Warrant Certificates. Irrespective of any adjustment in the Exercise Price or amount or kind of shares into which the Warrants are exercisable, Warrant Certificates theretofore or thereafter issued may continue to express the same Exercise Price initially applicable or amount or kind of shares initially issuable upon exercise of the Warrants evidenced thereby pursuant to this Agreement.

5.2 Fractional Interest. The Company shall not be required upon the exercise of any Warrant to issue any fractional shares, but may, in lieu of issuing any fractional shares of Common Stock make an adjustment therefore in cash on the basis of the Current Market Price per share of Common Stock on the date of such exercise. If Warrant Certificates evidencing more than one Warrant shall be presented for exercise at the same time by the same Holder, the number of full shares of Common Stock which shall be issuable upon such exercise thereof shall be computed on the basis of the aggregate number of Warrants so to be exercised. The Holders, by their acceptance of the Warrant Certificates, expressly waive their right to receive any fraction of a share of Common Stock or a stock certificate representing a fraction of a share of Common Stock.

5.3 No Other Adjustments. Except in accordance with Section 5.1, the applicable Exercise Price and the number of shares of Common Stock obtainable upon exercise of any Warrant will not be adjusted for the issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or carrying the right to purchase any of the foregoing, including, without limitation:

23

(i) upon the issuance of any other securities by the Company on or after the Original Issue Date, whether or not contemplated by the Plan, or upon the issuance of shares of Common Stock upon the exercise of any such securities;

(ii) upon the issuance of any shares of Common Stock or other securities or any payments pursuant to the Management Incentive Plan (as defined in the Plan) or any other equity incentive plan of the Company;

(iii) upon the issuance of any shares of Common Stock pursuant to the exercise of the Warrants; or

(iv) upon the issuance of any shares of Common Stock or other securities of the Company in connection with a business acquisition transaction.

If (a) any mutilated Warrant Certificate is surrendered to the Warrant Agent or (b) both (i) there shall be delivered to the Company and the Warrant Agent (A) a claim by a Holder as to the destruction, loss or wrongful taking of any Warrant Certificate of such Holder and a request thereby for a new replacement Warrant Certificate, and (B) such indemnity bond as may be required by them to save each of them and any agent of either of them harmless and (ii) such other reasonable requirements as may be imposed by the Company and the Warrant Agent as permitted by Section 8-405 of the Uniform Commercial Code have been satisfied, then, in the absence of notice to the Company or the Warrant Agent that such Warrant Certificate has been acquired by a “protected purchaser” within the meaning of Section 8-405 of the Uniform Commercial Code, the Company shall execute and upon its written request the Warrant Agent shall countersign and deliver to the registered Holder of the lost, wrongfully taken, destroyed or mutilated Warrant Certificate, in exchange therefore or in lieu thereof, a new Warrant Certificate of the same tenor and for a like aggregate number of Warrants. At the written request of such registered Holder, the new Warrant Certificate so issued shall be retained by the Warrant Agent as having been surrendered for exercise, in lieu of delivery thereof to such Holder, and shall be deemed for purposes of Section 3.2 to have been surrendered for exercise on the date the conditions specified in clauses (a) or (b) of the preceding sentence were first satisfied.

Upon the issuance of any new Warrant Certificate under this Section 6, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and other expenses (including the fees and expenses of the Warrant Agent and of counsel to the Company) in connection therewith.

Every new Warrant Certificate executed and delivered pursuant to this Section 6 in lieu of any lost, wrongfully taken or destroyed Warrant Certificate shall constitute an additional contractual obligation of the Company, whether or not the allegedly lost, wrongfully taken or destroyed Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder.

24

The provisions of this Section 6 are exclusive and shall preclude (to the extent lawful) all other rights or remedies with respect to the replacement of mutilated, lost, wrongfully taken, or destroyed Warrant Certificates.

The Company covenants that, for the duration of the Exercise Period, the Company will at all times reserve and keep available, from its authorized and unissued Common Stock solely for issuance and delivery upon the exercise of the Warrants and free of preemptive rights, such number of shares of Common Stock and other securities, cash or property as from time to time shall be issuable upon the exercise in full of all outstanding Warrants for cash. The Company further covenants that it shall, from time to time, take all steps necessary to increase the authorized number of shares of its Common Stock if at any time the authorized number of shares of Common Stock remaining unissued would otherwise be insufficient to allow delivery of all the shares of Common Stock then deliverable upon the exercise in full of all outstanding Warrants. The Company covenants that all shares of Common Stock issuable upon exercise of the Warrants will, upon issuance, be duly and validly issued, fully paid and nonassessable and will be free of restrictions on transfer and will be free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously or otherwise specified herein). The Company shall take all such actions as may be necessary to ensure that all such shares of Common Stock may be so issued without violation of any applicable law or governmental regulation or any requirements of any U.S. national securities exchange upon which shares of Common Stock may be listed (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance). The Company covenants that all shares of Common Stock will, at all times that Warrants are exercisable, be duly approved for listing subject to official notice of issuance on each securities exchange, if any, on which the Common Stock is then listed. The Company covenants that the stock certificates, if any, issued to evidence any shares of Common Stock issued upon exercise of Warrants will comply with the Delaware General Corporation Law and any other applicable law.

The Company hereby authorizes and directs its current and future transfer agents for the Common Stock at all times to reserve stock certificates for such number of authorized shares, to the extent as, and if, required. The Warrant Agent is hereby authorized to requisition from time to time from any such transfer agents stock certificates required to honor outstanding Warrants upon exercise thereof in accordance with the terms of this Agreement, and the Company hereby authorizes and directs such transfer agents to comply with all such requests of the Warrant Agent. The Company will supply such transfer agents with duly executed stock certificates for such purposes, to the extent as, and if, required.

The Warrant Agent will maintain an office (the “Corporate Agency Office”) in the United States of America, where Warrant Certificates may be surrendered for registration of transfer or exchange and where Warrant Certificates may be surrendered for exercise of Warrants evidenced thereby, which office is 1110 Centre Point Curve, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇, on the Original Issue Date. The Warrant Agent will give prompt written notice to all Holders of Warrant Certificates of any change in the location of such office.

25

The Warrant Certificates evidencing the Warrants shall be issued in registered form only. The Company shall cause to be kept at the office of the Warrant Agent designated for such purpose a warrant register (the “Warrant Register”) in which, subject to such reasonable regulations as the Warrant Agent may prescribe and such regulations as may be prescribed by law, the Company shall provide for the registration of Warrant Certificates and of transfers or exchanges of Warrant Certificates as herein provided.

Upon surrender for registration of transfer of any Warrant Certificate at the Corporate Agency Office, the Company shall execute, and the Warrant Agent shall countersign and deliver, in the name of the designated transferee or transferees, one or more new Warrant Certificates evidencing a like aggregate number of Warrants.

At the option of the Holder, Warrant Certificates may be exchanged at the office of the Warrant Agent upon payment of the charges hereinafter provided for other Warrant Certificates evidencing a like aggregate number of Warrants. Whenever any Warrant Certificates are so surrendered for exchange, the Company shall execute, and the Warrant Agent shall countersign and deliver, the Warrant Certificates of the same tenor and evidencing the same number of Warrants as evidenced by the Warrant Certificates surrendered by the Holder making the exchange.

All Warrant Certificates issued upon any registration of transfer or exchange of Warrant Certificates shall be the valid obligations of the Company, evidencing the same obligations, and entitled to the same benefits under this Agreement, as the Warrant Certificates surrendered for such registration of transfer or exchange.

Every Warrant Certificate surrendered for registration of transfer or exchange shall (if so required by the Company or the Warrant Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Warrant Agent, duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Warrant Certificates; provided, however, the Company may require payment 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 Warrant Certificates.

The Warrant Agent shall, upon request of the Company from time to time, deliver to the Company such reports of registered ownership of the Warrants and such records of transactions with respect to the Warrants and the shares of Common Stock as the Company may request. The Warrant Agent shall also make available to the Company for inspection by the Company’s agents or employees, from time to time as the Company may request, such original books of accounts and records maintained by the Warrant Agent in connection with the issuance and exercise of Warrants hereunder, such inspections to occur at the Corporate Agency Office during normal business hours.

The Warrant Agent shall keep copies of this Agreement and any notices given to Holders hereunder available for inspection by the Holders during normal business hours at the Corporate Agency Office. The Company shall supply the Warrant Agent from time to time with such numbers of copies of this Agreement as the Warrant Agency may request.

9.1 No Voting or Dividend Rights.

(a) No Holder of a Warrant Certificate evidencing any Warrant shall have or exercise any rights by virtue hereof as a holder of Common Stock of the Company, including, without limitation, the right to vote, to receive dividends and other distributions as a holder of Common Stock or to receive notice of, or attend, meetings or any other proceedings of the holders of Common Stock.

(b) The consent of any Holder of a Warrant Certificate shall not be required with respect to any action or proceeding of the Company.

(c) Except as provided in Section 4, no Holder of a Warrant Certificate, by reason of the ownership or possession of a Warrant or the Warrant Certificate representing the same, shall have any right to receive any cash dividends, stock dividends, allotments or rights or other distributions paid, allotted or distributed or distributable to the holders of Common Stock prior to, or for which the relevant record date preceded, the date of the exercise of such Warrant.

(d) No Holder of a Warrant Certificate shall have any right not expressly conferred hereunder or under, or by applicable law with respect to, the Warrant Certificate held by such Holder.

9.2 Rights of Action. All rights of action against the Company in respect of this Agreement, except rights of action vested in the Warrant Agent, are vested in the Holders of the Warrant Certificates, and any Holder of any Warrant Certificate, without the consent of the Warrant Agent or the Holder of any other Warrant Certificate, may, in such Holder’s own behalf and for such Holder’s own benefit, enforce and may institute and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, such Holder’s right to exercise such Holder’s Warrants in the manner provided in this Agreement.

9.3 Treatment of Holders of Warrant Certificates. Every Holder, by virtue of accepting a Warrant Certificate, consents and agrees with the Company, with the Warrant Agent and with every subsequent holder of such Warrant Certificate that, prior to due presentment of such Warrant Certificate for registration of transfer, the Company and the Warrant Agent may treat the Person in whose name the Warrant Certificate is registered as the owner thereof for all purposes and as the Person entitled to exercise the rights granted under the Warrants, and neither the Company, the Warrant Agent nor any agent thereof shall be affected by any notice to the contrary.

10.1 Nature of Duties and Responsibilities Assumed. The Company hereby appoints the Warrant Agent to act as agent of the Company as set forth in this Agreement. The Warrant Agent hereby accepts the appointment as agent of the Company and agrees to perform that agency upon the terms and conditions set forth in this Agreement and in the Warrant Certificates or as the Company and the Warrant Agent may hereafter agree, by all of which the Company and the Holders of Warrant Certificates, by their acceptance thereof, shall be bound; provided, however, that the terms and conditions contained in the Warrant Certificates are subject to and governed by this Agreement or any other terms and conditions hereafter agreed to by the Company and the Warrant Agent.

27

The Warrant Agent shall not, by countersigning Warrant Certificates or by any other act hereunder, be deemed to make any representations as to validity or authorization of (i) the Warrants or the Warrant Certificates (except as to its countersignature thereon), (ii) any securities or other property delivered upon exercise of any Warrant, (iii) the accuracy of the computation of the number or kind or amount of stock or other securities or other property deliverable upon exercise of any Warrant or (iv) the correctness of any of the representations of the Company made in such certificates that the Warrant Agent receives. The Warrant Agent shall not at any time have any duty to calculate or determine whether any facts exist that may require any adjustments pursuant to Section 5 hereof with respect to the kind and amount of shares or other securities or any property issuable to Holders upon the exercise of Warrants required from time to time. The Warrant Agent shall have no duty or responsibility to determine the accuracy or correctness of such calculation or with respect to the methods employed in making the same. The Warrant Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock or of any securities or property which may at any time be issued or delivered upon the exercise of any Warrant or upon any adjustment pursuant to Section 5 hereof, and it makes no representation with respect thereto. The Warrant Agent shall not be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property upon the surrender of any Warrant Certificate for the purpose of exercise or upon any adjustment pursuant to Section 5 hereof or to comply with any of the covenants of the Company contained in Section 5 hereof.

The Warrant Agent shall not (i) be liable for any recital or statement of fact contained herein or in the Warrant Certificates or for any action taken, suffered or omitted by it in good faith on the belief that any Warrant Certificate or any other documents or any signatures are genuine or properly authorized, (ii) be responsible for any failure on the part of the Company to comply with any of its covenants and obligations contained in this Agreement or in the Warrant Certificates or (iii) be liable for any act or omission in connection with this Agreement except for its own gross negligence, bad faith or willful misconduct (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction).

The Warrant Agent is hereby authorized to accept and protected in accepting instructions with respect to the performance of its duties hereunder by Company Order and to apply to any such officer named in such Company Order for instructions (which instructions will be promptly given in writing when requested), and the Warrant Agent shall not be liable for any action taken or suffered to be taken by it in good faith in accordance with the instructions in any Company Order.

The Warrant Agent may execute and exercise any of the rights and powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys, agents or employees; provided, however, reasonable care has been exercised in the selection and in the continued employment of any such attorney, agent or employee. The Warrant Agent shall not be under any obligation or duty to institute, appear in or defend any action, suit or legal proceeding in respect hereof, unless first indemnified to its satisfaction, but this provision shall not affect the power of the Warrant Agent to take such action as the Warrant Agent may consider proper, whether with or without such indemnity. The Warrant Agent shall promptly notify the Company in writing of any claim made or action, suit or proceeding instituted against it arising out of or in connection with this Agreement.

28

The Company shall perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further acts, instruments and assurances as may reasonably be required by the Warrant Agent in order to enable it to carry out or perform its duties under this Agreement.

The Warrant Agent shall act solely as agent of the Company hereunder and does not assume any obligation or relationship of agency or trust for or with any of the Holders or any beneficial owners of Warrants. The Warrant Agent shall not be liable except for the failure to perform such duties as are specifically set forth herein or specifically set forth in the Warrant Certificates, and no implied covenants or obligations shall be read into this Agreement against the Warrant Agent whose duties and obligations shall be determined solely by the express provisions hereof or the express provisions of the Warrant Certificates.

10.2 Right to Consult Counsel. The Warrant Agent may at any time consult with legal counsel satisfactory to it (who may be legal counsel for the Company), and the Warrant Agent shall incur no liability or responsibility to the Company or to any Holder for any action taken, suffered or omitted by it in good faith in accordance with the opinion or advice of such counsel.

10.3 Compensation, Reimbursement and Indemnification. The Company agrees to pay the Warrant Agent from time to time compensation for all fees and expenses relating to its services hereunder as the Company and the Warrant Agent may agree from time to time and to reimburse the Warrant Agent for reasonable expenses and disbursements, including reasonable counsel fees incurred in connection with the execution and administration of this Agreement. The Company further agrees to indemnify the Warrant Agent for and hold it harmless against any losses, liabilities or reasonable expenses arising out of or in connection with the acceptance and administration of this Agreement, including the reasonable costs, legal fees and expenses of investigating or defending any claim of such liability, except that the Company shall have no liability hereunder to the extent that any such loss, liability or expense results from the Warrant Agent’s own gross negligence, bad faith or willful misconduct (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction).

10.4 Warrant Agent May Hold Company Securities. The Warrant Agent, any Countersigning Agent and any stockholder, director, officer or employee of the Warrant Agent or any Countersigning Agent may buy, sell or deal in any of the warrants or other securities of the Company or its Affiliates, become pecuniarily interested in transactions in which the Company or its Affiliates may be interested, contract with or lend money to the Company or its Affiliates or otherwise act as fully and freely as though it were not the Warrant Agent or the Countersigning Agent, respectively, under this Agreement. Nothing herein shall preclude the Warrant Agent or any Countersigning Agent from acting in any other capacity for the Company or for any other legal entity.

29

10.5 Resignation and Removal; Appointment of Successor.

(a) The Warrant Agent may resign its duties and be discharged from all further duties and liability hereunder (except liability arising as a result of the Warrant Agent’s own gross negligence or willful misconduct) after giving 30 days’ prior written notice to the Company. The Company may remove the Warrant Agent upon 30 days’ written notice, and the Warrant Agent shall thereupon in like manner be discharged from all further duties and liabilities hereunder, except as aforesaid. The Warrant Agent shall, at the expense of the Company, cause notice to be given in accordance with Section 11.1(b) to each Holder of a Warrant Certificate of said notice of resignation or notice of removal, as the case may be. Upon such resignation or removal, the Company shall appoint in writing a new Warrant Agent. If the Company shall fail to make such appointment within a period of 30 calendar days after it has been notified in writing of such resignation by the resigning Warrant Agent or after such removal, then the Holder of any Warrant Certificate may apply to any court of competent jurisdiction for the appointment of a new Warrant Agent. Any new Warrant Agent, whether appointed by the Company or by such a court, shall be a corporation doing business under the laws of the United States or any state thereof in good standing, authorized under such laws to act as Warrant Agent, and having a combined capital and surplus of not less than $25,000,000. The combined capital and surplus of any such new Warrant Agent shall be deemed to be the combined capital and surplus as set forth in the most recent annual report of its condition published by such Warrant Agent prior to its appointment; provided, however, such reports are published at least annually pursuant to law or to the requirements of a Federal or state supervising or examining authority. After acceptance in writing of such appointment by the new Warrant Agent, it shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the Warrant Agent, without any further assurance, conveyance, act or deed; but if for any reason it shall be reasonably necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the reasonable expense of the Company and shall be legally and validly executed and delivered by the resigning or removed Warrant Agent. Not later than the effective date of any such appointment, the Company shall file notice thereof with the resigning or removed Warrant Agent. Failure to give any notice provided for in this Section 10.5(a), however, or any defect therein, shall not affect the legality or validity of the resignation of the Warrant Agent or the appointment of a new Warrant Agent as the case may be.

(b) Any Person into which the Warrant Agent or any new Warrant Agent may be merged, or any corporation resulting from any consolidation to which the Warrant Agent or any new Warrant Agent shall be a party, shall be a successor Warrant Agent under this Agreement without any further act; provided, that, such corporation would be eligible for appointment as successor to the Warrant Agent under the provisions of Section 10.5(a). Any such successor Warrant Agent shall promptly cause notice of its succession as Warrant Agent to be given in accordance with Section 11.1(b) to each Holder of a Warrant Certificate at such Holder’s last address as shown on the Warrant Register.

10.6 Appointment of Countersigning Agent.

(a) The Warrant Agent may appoint a Countersigning Agent or Agents which shall be authorized to act on behalf of the Warrant Agent to countersign Warrant Certificates issued upon original issue and upon exchange, registration of transfer or pursuant to Section 6, and Warrant Certificates so countersigned shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered

30

hereunder. Wherever reference is made in this Agreement to the countersignature and delivery of Warrant Certificates by the Warrant Agent or to Warrant Certificates countersigned by the Warrant Agent, such reference shall be deemed to include countersignature and delivery on behalf of the Warrant Agent by a Countersigning Agent and Warrant Certificates countersigned by a Countersigning Agent. Each Countersigning Agent shall be acceptable to the Company and shall at the time of appointment be a corporation doing business under the laws of the United States of America or any State thereof in good standing, authorized under such laws to act as Countersigning Agent, and having a combined capital and surplus of not less than $25,000,000. The combined capital and surplus of any such new Countersigning Agent shall be deemed to be the combined capital and surplus as set forth in the most recent annual report of its condition published by such Countersigning Agent prior to its appointment; provided, however, such reports are published at least annually pursuant to law or to the requirements of a Federal or state supervising or examining authority.

(b) Any Person into which a Countersigning Agent may be merged or any corporation resulting from any consolidation to which such Countersigning Agent shall be a party, shall be a successor Countersigning Agent without any further act; provided, that, such corporation would be eligible for appointment as a new Countersigning Agent under the provisions of Section 10.6(a), without the execution or filing of any paper or any further act on the part of the Warrant Agent or the Countersigning Agent. Any such successor Countersigning Agent shall promptly cause notice of its succession as Countersigning Agent to be given in accordance with Section 11.1(b) to each Holder of a Warrant Certificate at such Holder’s last address as shown on the Warrant Register.

(c) A Countersigning Agent may resign at any time by giving 30 days’ prior written notice thereof to the Warrant Agent and to the Company. The Warrant Agent may at any time terminate the agency of a Countersigning Agent by giving 30 days’ prior written notice thereof to such Countersigning Agent and to the Company.

(d) The Warrant Agent agrees to pay to each Countersigning Agent from time to time reasonable compensation for its services under this Section 10.6 and the Warrant Agent shall be entitled to be reimbursed for such payments, subject to the provisions of Section 10.3.

(e) Any Countersigning Agent shall have the same rights and immunities as those of the Warrant Agent set forth in Section 10.1.

11.1 Notices Generally.

(a) Any request, notice, direction, authorization, consent, waiver, demand or other communication permitted or authorized by this Agreement to be made upon, given or furnished to or filed with the Company or the Warrant Agent by the other party hereto or by any Holder shall be sufficient for every purpose hereunder if in writing (including telecopy communication) and telecopied or delivered by hand (including by courier service) as follows:

or, in either case, such other address as shall have been set forth in a notice delivered in accordance with this Section 11.1(a).

All such communications shall, when so telecopied or delivered by hand, be effective when telecopied with confirmation of receipt or received by the addressee, respectively.

Any Person that telecopies any communication hereunder to any Person shall, on the same date as such telecopy is transmitted, also send, by first class mail, postage prepaid and addressed to such Person as specified above, an original copy of the communication so transmitted.

(b) Where this Agreement provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the address of such Holder as it appears in the Warrant Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made by a method approved by the Warrant Agent as one which would be most reliable under the circumstances for successfully delivering the notice to the addressees shall constitute a sufficient notification for every purpose hereunder.

32

Where this Agreement provides for notice of any event to a Holder of a Global Warrant Certificate, such notice shall be sufficiently given if given to the Depositary (or its designee), pursuant to its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice.

11.2 Required Notices to Holders. In the event the Company shall:

(a) take any action that would result (or, but for the third paragraph of Section 5.1(d) or the third paragraph of Section 5.1(e), would have resulted) in (x) an adjustment to the Exercise Price and/or the number of shares of Common Stock issuable upon exercise of a Warrant pursuant to Section 5.1 or (y) any dividend or distribution to holders of the Common Stock that does not constitute a Special Dividend or a Spin-Off Dividend;

(b) consummate any Winding Up; or

(c) consummate any Sale Transaction (each of (a), (b) or (c), an “Action”);

then, in each such case, unless the Company has made a filing with the Commission, including pursuant to a Current Report on Form 8-K, which filing discloses such Action, the Company shall cause to be delivered to the Warrant Agent and shall give to each Holder of a Warrant Certificate, in accordance with Section 11.1(b) hereof, a written notice of such Action, including, in the case of an action pursuant to Section 11.2(a), the information required under Section 5.1(l)(ii). Such notice shall be given promptly after (or, in the case of an Action specified in clause (a)(y) or the parenthetical in clause (a), at least five (5) Business Days prior to) the earlier of (i) the effective date of such Action or (ii) the date for the determination of the holders of Common Stock entitled to receive any dividend or distribution or otherwise participate in such Action.

If at any time the Company shall cancel any of the Actions for which notice has been given under this Section 11.2 prior to the consummation thereof, the Company shall give each Holder prompt notice of such cancellation in accordance with Section 11.1(b), unless the Company has made a filing with the Commission, including pursuant to a current report on Form 8-K, which filing discloses the cancellation of such Actions.

In addition, in the event the Company enters into any definitive agreement with respect to any Sale Transaction, unless the Company has made a filing with the Commission, including pursuant to a Current Report on Form 8-K, which filing discloses such agreement, the Company shall cause to be delivered to the Warrant Agent and shall give to each Holder of a Warrant Certificate, in accordance with Section 11.1(b), a notice of the entering into such definitive agreement.

The Warrant Agent shall cause a copy of this Agreement to be available at all reasonable times at the office of the Warrant Agent for inspection by any Holder of any Warrant Certificate. The Warrant Agent may require any such Holder to submit its Warrant Certificate for inspection by the Warrant Agent.

33

(a) Subject to Section 13(c), this Agreement may be amended by the Company and the Warrant Agent with the consent of the Required Warrant Holders.

(b) Notwithstanding the foregoing, subject to Section 13(c), the Company and the Warrant Agent may, without the consent or concurrence of the Holders of the Warrant Certificates, by supplemental agreement or otherwise, amend this Agreement for the purpose of making any changes or corrections in this Agreement that (i) are required to cure any ambiguity or to correct or supplement any defective or inconsistent provision or clerical omission or mistake or manifest error herein contained or (ii) add to the covenants and agreements of the Company in this Agreement further covenants and agreements of the Company thereafter to be observed, or surrender any rights or powers reserved to or conferred upon the Company in this Agreement; provided, however, that in either case such amendment shall not adversely affect the rights or interests of the Holders of the Warrant Certificates hereunder in any material respect.

(c) The consent of each Holder of any Warrant Certificate evidencing any Warrants affected thereby shall be required for any supplement or amendment to this Agreement or the Warrants that would: (i) increase the Exercise Price or decrease the number of shares of Common Stock receivable upon exercise of Warrants, in each case other than as provided in Section 5.1; (ii) the Expiration Date is changed to an earlier date; or (iii) modify the provisions contained in Section 5.1 in a manner adverse to the Holders of Warrant Certificates generally with respect to their Warrants.

(d) The Warrant Agent shall join with the Company in the execution and delivery of any such amendment unless such amendment affects the Warrant Agent’s own rights, duties or immunities hereunder, in which case the Warrant Agent may, but shall not be required to, join in such execution and delivery; provided, that, as a condition precedent to the Warrant Agent’s execution of any amendment to this Agreement, the Company shall deliver to the Warrant Agent a certificate from an Appropriate Officer that states that the proposed amendment is in compliance with the terms of this Section 13. Upon execution and delivery of any amendment pursuant to this Section 13, such amendment shall be considered a part of this Agreement for all purposes and every Holder of a Warrant Certificate theretofore or thereafter countersigned and delivered hereunder shall be bound thereby.

(e) Promptly after the execution by the Company and the Warrant Agent of any such amendment, unless the Company has made a filing with the Commission, including pursuant to a current report on Form 8-K, which filing discloses such adjustment, the Company shall give notice to the Holders of Warrant Certificates, setting forth in general terms the substance of such amendment, in accordance with the provisions of Section 11.1(b). Any failure of the Company to mail such notice or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment.

34

The Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Required Warrant Holders as required pursuant to Section 13 and, if Section 13(c) applies, the consent of the Holders of any Warrant Certificates evidencing any Warrants affected thereby.

So long as Warrants remain outstanding, the Company will not enter into any Non-Surviving Transaction in which Warrants would be outstanding after consummation unless the acquirer (a “Successor Company”) shall expressly assume by a supplemental agreement, executed and delivered to the Warrant Agent, in form reasonably satisfactory to the Warrant Agent, the due and punctual performance of every covenant of this Agreement on the part of the Company to be performed and observed and shall have provided for exercise rights in accordance with Section 5.1(h). Upon the consummation of such Non-Surviving Transaction, the acquirer shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Agreement with the same effect as if such acquirer had been named as the Company herein.

The section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement.

This Agreement may be executed in two or more counterparts, each of which will be deemed to be an original, but all of which together constitute one and the same instrument.

The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision hereof will not affect the validity or enforceability of the other provisions hereof; provided, that, if any provision of this Agreement, as applied to any party or to any circumstance, is adjudged by a court or governmental body not to be enforceable in accordance with its terms, the parties agree that the court or governmental body making such determination will have the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.

The Warrants shall not be subject to redemption by the Company or any other Person; provided, that, the Warrants may be acquired by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of this Agreement.

35

This Agreement shall be binding upon and inure to the benefit of the Company, the Warrant Agent and the Holders from time to time. Nothing in this Agreement, express or implied, is intended to confer upon any person other than the Company, the Warrant Agent and the Holders any rights or remedies under or by reason of this Agreement or any part hereof, and all covenants, conditions, stipulations, promises and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and of the Holders.

WARRANTS TO PURCHASE COMMON STOCK

The Warrants evidenced hereby are one of a duly authorized issue of Warrants of the Company designated as its Warrants to Purchase Common Stock (“Warrants”), limited in aggregate number to 2,580,182 issued under and in accordance with the Warrant Agreement, to which the Warrant Agreement and all amendments thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Warrant Agent, the Holders of Warrant Certificates and the owners of the Warrants evidenced thereby and of the terms upon which the Warrant Certificates are, and are to be, countersigned and delivered. A copy of the Warrant Agreement shall be available at all reasonable times at the office of the Warrant Agent for inspection by the Holder hereof.

The Warrant Agreement provides that, in addition to certain adjustments to the number of shares of Common Stock into which a Warrant is exercisable and the Exercise Price required to be made in certain circumstances, (x) in the case of any Transaction that is a Redomestication Transaction, a Non-Sale Transaction, a Sale Cash and Securities Transaction or a Sale Securities Only Transaction, the Company shall (or, in the case of any Non-Surviving Transaction, the Company shall cause the other Person involved in such Transaction to) execute and deliver to the Warrant Agent a written instrument providing that (i) the Warrants evidenced hereby, if then outstanding, will be exercisable thereafter, during the period the Warrants evidenced hereby shall be exercisable as specified herein, only into the Substituted Securities (in the case of any Sale Securities Only Transaction or Sale Cash and Securities Transaction) or Substituted Property (in the case of any Transaction (other than a Sale Transaction)), subject to certain limitations if the Warrants have no value, that would have been receivable upon such Transaction by a Qualifying Person holding the number of shares of Common Stock that would have been issued upon exercise of such Warrant if such Warrant had been exercised in full immediately prior to such Transaction (upon certain assumptions specified in the Warrant Agreement); (ii) in the case of any Sale Cash and Securities Transaction, the aggregate Exercise Price for any Warrant will be reduced in respect of the Cash Consideration receivable upon such Transaction by a Qualifying Person holding such number of shares of Common Stock; and (iii) the rights and obligations of the Company (or, in the case of any Non-Surviving Transaction, the other Person involved in such Transaction) and the holders in respect of Substituted Securities shall be substantially unchanged to be as nearly equivalent as may be practicable to the rights and obligations of the Company and Holders in respect of Common Stock, and (y) in the case of any Sale Cash Only Transaction, the Company shall make certain specified payments of cash and the Warrants will expire or become immediately exercisable, in each case as more fully specified in the Warrant Agreement.

A-4

Except as provided in the Warrant Agreement, all outstanding Warrants shall expire, terminate and become void and all rights of the Holders of Warrant Certificates evidencing such Warrants shall automatically terminate and cease to exist, as of 5:00 p.m., New York time, on the Expiration Date. The “Expiration Date” shall mean the earlier to occur of (x) September 26, 2024 5:00 p.m. New York time (the fifth and a half (5 1/2) anniversary of the Original Issue Date) or, if not a Business Day, then the next Business Day thereafter; (y) the date of consummation of any Sale Cash Only Transaction; and (z) a Winding Up.

In the event of the exercise of less than all of the Warrants evidenced hereby, a new Warrant Certificate of the same tenor and for the number of Warrants which are not exercised shall be issued by the Company in the name or upon the written order of the Holder of this Warrant Certificate upon the cancellation hereof.

The Warrant Certificates are issuable only in registered form in denominations of whole numbers of Warrants. Upon surrender at the office of the Warrant Agent and payment of the charges specified herein and in the Warrant Agreement, this Warrant Certificate may be exchanged for Warrant Certificates in other authorized denominations or the transfer hereof may be registered in whole or in part in authorized denominations to one or more designated transferees; provided, however, that such other Warrant Certificates issued upon exchange or registration of transfer shall evidence the same aggregate number of Warrants as this Warrant Certificate. The Company shall cause to be kept at the office of the Warrant Agent the Warrant Register in which, subject to such reasonable regulations as the Warrant Agent may prescribe and such regulations as may be prescribed by law, the Company shall provide for the registration of Warrant Certificates and of transfers or exchanges of Warrant Certificates. No service charge shall be made for any registration of transfer or exchange of Warrant Certificates; provided, however, the Company may require payment 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 Warrant Certificates.

Prior to due presentment of this Warrant Certificate for registration of transfer, the Company, the Warrant Agent and any agent of the Company or the Warrant Agent may treat the Person in whose name this Warrant Certificate is registered as the owner hereof for all purposes, and neither the Company, the Warrant Agent nor any such agent shall be affected by notice to the contrary.

The Warrant Agreement permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of Warrant Certificates under the Warrant Agreement at any time by the Company and the Warrant Agent with the consent of the Required Warrant Holders.

Until the exercise of any Warrant, subject to the provisions of the Warrant Agreement and except as may be specifically provided for in the Warrant Agreement, (i) no Holder of a Warrant Certificate evidencing any Warrant shall have or exercise any rights by virtue hereof as a holder of Common Stock of the Company, including, without limitation, the right to vote, to receive dividends and other distributions or to receive notice of, or attend meetings of, stockholders or any other proceedings of the Company; (ii) the consent of any such Holder shall not be required with respect to any action or proceeding of the Company; (iii) except as provided with respect to a Winding Up of the Company, no such Holder, by reason of the ownership or possession of a Warrant or the Warrant Certificate representing the same, shall have any right to receive any cash dividends, stock dividends, allotments or rights or other distributions (except as specifically

A-5

provided in the Warrant Agreement), paid, allotted or distributed or distributable to the stockholders of the Company prior to or for which the relevant record date preceded the date of the exercise of such Warrant; and (iv) no such Holder shall have any right not expressly conferred by the Warrant or Warrant Certificate held by such Holder.

This Warrant Certificate, each Warrant evidenced thereby and the Warrant Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of New York or any other jurisdiction) to the extent such rules or provisions would cause the application of the laws of any jurisdiction other than the State of New York. Any action to enforce the this Warrant Certificate, each Warrant evidenced thereby and the Warrant Agreement or any dispute, whether such dispute arises in law or equity, arising out of or relating to this Warrant Certificate, each Warrant evidenced thereby and the Warrant Agreement shall be brought exclusively in the United States District Court for the Southern District of New York or any New York State Court sitting in New York City.

All terms used in this Warrant Certificate which are defined in the Warrant Agreement shall have the meanings assigned to them in the Warrant Agreement. In the event of any conflict between this Warrant Certificate and the Warrant Agreement, the Warrant Agreement shall control.
