Thereupon, the Holder shall be entitled to receive the applicable number of duly authorized, validly issued, fully paid and nonassessable Warrant Shares. Notwithstanding the foregoing, each exercise of the Warrant by the Holder must be for at least 1,000,000 Warrant Shares; provided, however, that the Warrant may be exercised for a lower number of Warrant Shares if such exercise is for all remaining Warrant Shares subject to the Warrant.

2.2 Delivery of Stock Certificates on Exercise.

2.7 Limitation on Exercise by Transferees. In the event this Warrant is transferred in accordance with Section 5, this Warrant shall not be exercisable (i) to the extent that, on or immediately after exercise, the representations in Section 3.2(d) of the Securities Purchase Agreement would be untrue with respect to the person exercising the Warrant and such person’s Tax Affiliates, and (ii) unless and until the person exercising the Warrant makes such representations and performs the Tax Covenants. For purposes of this Section 2.7, references to the Purchaser and its Tax Affiliates in Section 3.2(d) of the Securities Purchase Agreement and in the Tax Covenants shall be treated as referring to the person exercising the Warrant and such person’s Tax Affiliates.

2.8 The provisions of Section 4.2(g) of the Securities Purchase Agreement shall apply hereto, to the extent relevant to the provisions hereof, substituting “Holder” for “Purchaser” therein.

3. Adjustment of Exercise Price and Warrant Shares. The Exercise Price and the number of Warrant Shares shall be subject to adjustment from time to time upon the happening of certain events as described in this Section 3.

3.1 Subdivision or Combination of Stock. If at any time or from time to time after the date hereof, the Company shall subdivide (by way of stock dividend, stock split or otherwise) its outstanding shares of Common Stock, the Exercise Price in effect immediately prior to such subdivision shall be reduced proportionately and the number of Warrant Shares (calculated to the nearest whole share) shall be increased proportionately, and conversely, in the event the outstanding shares of Common Stock shall be combined (whether by stock combination, reverse stock split or otherwise) into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be increased proportionately and the number of Warrant Shares (calculated to the nearest whole share) shall be decreased proportionately. The Exercise Price and the number of Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3.1.

3.2 Adjustment for Stock Dividends. If at any time after the date hereof, the Company shall declare a dividend or make any other distribution upon any class or series of stock of the Company payable in shares of Common Stock, the Exercise Price in effect immediately prior to such declaration or distribution shall be reduced proportionately and the number of Warrant Shares (calculated to the nearest whole share) shall be increased proportionately, to reflect the issuance of any shares of Common Stock, issuable in payment of such dividend or distribution. The Exercise Price and the number of Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3.2.

3.3 Adjustments for Reclassifications. If the Common Stock issuable upon the exercise of this Warrant shall be changed into the same or a different number of shares of any class(es) or series of stock and/or the right to receive property, whether by reclassification or otherwise (other than an adjustment under Sections 3.1 and 3.2 or a merger, consolidation, or sale of assets provided for under Section 3.4), then and in each such event, the Holder hereof shall have the right thereafter to convert each Warrant Share into the kind and amount of shares of stock and other securities and property receivable upon such reclassification, or other change by holders of the number of shares of Common Stock into which such Warrant Shares would have been convertible immediately prior to such reclassification or change, all subject to successive adjustments thereafter from time to time pursuant to and in accordance with, the provisions of this Section 3.

3.4 Adjustments for Merger or Consolidation.

(a) If during the Warrant Term a Change of Control or plan or proposal with respect thereto is publicly announced or occurs, and the Acquiring Person (as defined in the Securities Purchase Agreement) (or its direct or indirect parent entity) does not have a class of common equity securities listed or admitted for trading on any securities exchange or over-the-counter or other organized market, whether U.S. or not, then this Warrant shall terminate upon the effective date Change of Control; provided that between the date such Change of Control is announced and the effective date of the Change of Control, but not thereafter, the Holder shall have the right to submit to the Company an exercise notice (which exercise notice may, at the Holder’s option, specify that the exercise and payment of the Exercise Price shall occur simultaneously with, and be contingent upon, the occurrence of the Change of Control) in accordance with the terms and conditions of this Warrant; provided, however, that so long as the Company has provided the Holder with at least five (5) Business Days (as defined in the Securities Purchase Agreement) advance written notice of the effective date for the Change of Control, the Company shall not be required to postpone such closing date in order to facilitate the closing of the exercise.

(b) If during the Warrant Term a Change of Control or plan or proposal with respect thereto is publicly announced or occurs, and the Acquiring Person (or its direct or indirect parent entity) has a class of common equity securities listed or admitted for trading on any securities exchange or over-the-counter or other organized market, whether U.S. or not, then:

(i) Between the date such Change of Control is announced and the effective date of the Change of Control, the Holder shall have the right to submit to the Company an exercise notice (which exercise notice may, at the Holder’s option, specify that the exercise and payment of the Exercise Price shall occur simultaneously with, and be contingent upon, the occurrence of the Change of Control) in accordance with the terms and conditions of this Warrant; provided, however, that so long as the Company has provided the Holder with at least five (5) Business Days advance written notice of the effective date for the Change of Control, the Company shall not be required to postpone such closing date in order to facilitate the closing of the exercise;

(ii) The Company shall not enter into an agreement with the Acquiring Person resulting in such Change of Control unless such agreement expressly obligates the Acquiring Person to assume all of the Company’s obligations under this Warrant; and

(iii) In the event that any portion of this Warrant remains unexercised upon consummation of the Change of Control, the Holder shall thereafter automatically have equivalent rights with respect to the Acquiring Person, and from and after the effective date of the Change of Control and regardless of whether the Acquiring Person expressly assumes the Company’s obligations:

(A) all references to the Company in this Warrant shall be references to the Acquiring Person,

(B) all references to Common Stock in this Warrant shall be references to the securities for which the Common Stock are exchanged in the Change of Control (or if none, the most widely-held class of common equity securities of the Acquiring Person),

(C) the Exercise Price shall be adjusted, employing the methodology set forth in the example(s) on Annex I hereto, to equal the Exercise Price as in effect immediately prior to the Change of Control multiplied by a fraction, (1) the numerator of which is the volume-weighted average price, calculated to the nearest ten thousandth (i.e., four decimal places (.xxxx)), of the securities for which Common Stock is exchanged in the Change of Control (or if none, the most widely-held class of voting common equity securities of the Acquiring Person), and (2) the denominator of which is the Daily Market Price of the Company, in the case of (1) and (2) determined as of the Business Day immediately preceding and excluding the date on which the Change of Control is consummated. For purposes of this Warrant, “Daily Market Price” has the meaning given in the Securities Purchase Agreement, substituting references to the “Holder” for the “Purchaser,” and

(D) the number of Warrant Shares shall be adjusted, employing the methodology set forth in the example(s) on Annex I hereto, to equal the product of the number of Warrant Shares in effect immediately prior to the Change of Control multiplied by a fraction, (1) the numerator of which is the Daily Market Price of the Company, and (2) the denominator of which is the volume-weighted average price, calculated to the nearest ten thousandth (i.e., four decimal places (.xxxx)), of the securities for which Common Stock is exchanged in the Change of Control (or if none, the most widely-held class of voting common equity securities of the Acquiring Person), in the case of (1) and (2) determined as of the Business Day immediately preceding and excluding the date on which the Change of Control is consummated.

3.5 Minimum Adjustment of Exercise Price. If the amount of any adjustment of the Exercise Price required pursuant to this Section 3 would be less than one-tenth (1/10) of one percent (1%) of the Exercise Price in effect at the time such adjustment is otherwise so required to be made, such amount shall be carried forward and adjustment with respect thereto 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 at least one tenth (1/10) of one percent (1%) of such Exercise Price.

3.6 Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Exercise Price and number of Warrant Shares pursuant to this Section 3, this Warrant shall, without any action on the part of the Holder, be adjusted in accordance with this Section 3, and the Company, at its expense, promptly shall compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to the Holder a certificate setting forth such adjustment or readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Company will forthwith send a copy of each such certificate to the Holder in accordance with Section 7.4 below.

4. Notices of Record Date. Upon (a) any establishment by the Company of a record date of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or right or option to acquire securities of the Company, or any other right, or (b) any capital reorganization, reclassification, recapitalization, merger or consolidation of the Company with or into any other Person, any transfer of all or substantially all the assets of the Company, or any voluntary or involuntary dissolution, liquidation or winding up of the Company, or the sale, in a single transaction, of a majority of the Company’s voting stock (whether newly issued, or from treasury, or previously issued and then outstanding, or any combination thereof), the Company shall mail to the Holder at least ten (10) Business Days, or such longer period as may be required by law, prior to the record date specified therein and at least ten (10) Business Days prior to the date specified in clause (ii) or (iii) hereof, a notice specifying (i) the date established as the record date for the purpose of such dividend, distribution, option or right and a description of such dividend, distribution, option or right, (ii) the date on which any such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up, or sale is expected to become effective and (iii) the date, if any, fixed as to when the holders of record of Common Stock shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up. Subject to the other limitations on exercise contained in this Warrant, nothing in this Section 4 shall prohibit the Holder from exercising this Warrant during the ten (10) Business Day period commencing on the date of such notice.

5. Transfer Provisions, etc.

5.1 Limitations on Transfer. None of the Holder, or any subsequent successor, transferee or assign, shall sell or otherwise transfer this Warrant to any Person unless and until (1) the transferee makes the representations in Section 3.2(d) of the Securities Purchase Agreement, agrees to perform and, to the extent then applicable, performs the Tax Covenants and (2) the transferor and the transferee, each represent in writing, under penalty of perjury, that it does not have a principal purpose of avoiding or ameliorating the impact of an ownership change within the meaning of Treasury Regulation Section 1.382-4(d) related to the transfer of the Warrant. For purposes of this Section 5.1, references to the Purchaser and its Tax Affiliates in Section 3.2(d) and in the Tax Covenants of the Securities Purchase Agreement shall be treated as referring to the transferee and its Tax Affiliates. Upon any transfer by the Holder, or any subsequent successor, transferee or assign, such Person shall deliver to the Company the Notice of Transfer, in the form attached hereto.

5.2 Warrant Register. The Company shall keep at its principal office a register for the registration, and registration of transfers, of the Warrants.
