“7.3 Effect of Certain Events and Transactions.

(a) If this Warrant shall not have been exercised in full before the expiration of the Exercise Period, then this Warrant shall be automatically exercised, without further action on the part of the Holder, in full (and the Holder shall be deemed to have become a holder of the Shares issuable upon such automatic exercise) on and as of the date on which the Exercise Period is scheduled to expire unless, either (i) at any time before the expiration of the Exercise Period, the Holder shall notify the Company in writing that no such automatic exercise is to occur or (ii) the fair market value per share of the Company’s capital stock of the same class and series as the Shares as of the time immediately preceding the expiration of the Exercise Period is less than the Exercise Price then in effect. Unless the Holder otherwise notifies the Company in writing or the fair market value per share of the Company’s capital stock of the same class and series as the Shares as of the time immediately preceding the expiration of the Exercise Period is less than the Exercise Price then in effect, the Holder shall be deemed to have elected to pay the Exercise Price due in connection with such automatic exercise pursuant to this Section 7(a) pursuant to the provisions of Section 2.6. If the Holder has advised the Company in writing before the Expiration Date that no automatic exercise under this Section 7.3(a) is to occur or if the fair market value per share of the Company’s capital stock of the same class and series as the Shares as of the time immediately preceding the expiration of the Exercise Period is less than the Exercise Price then in effect, then this Warrant shall become void, and all rights to exercise the unexercised portion of this Warrant and all rights in respect of such unexercised portion of this Warrant shall cease immediately after expiration of the Exercise Period.

(b) If there shall be a Liquidation (as defined in the Company’s certificate of incorporation, as amended and/or restated from time to time) of the Company while this Warrant remains outstanding pursuant to which the price per share to be paid or distributed for or in respect of shares of the Company’s capital stock of the same class and series as the Shares is less than the Exercise Price in effect at the time immediately preceding the consummation of such Liquidation and such consideration is in the form of all cash and/or marketable securities, then this Warrant shall automatically terminate as of the time immediately following the consummation of such Liquidation.

(c) Except as is provided in Section 7.3(d), in the event of a Liquidation of the Company while this Warrant remains outstanding pursuant to which the per share price to be paid or distributed for or in respect of shares of the Company’s capital stock of the same class and series as the Shares is greater than the Exercise Price in effect at the time immediately preceding the consummation of such Liquidation and such consideration is in the form of all cash and/or marketable securities, the Holder may by written notice to the Company (an “Election Notice”) either:

(i) give notice of its intent to exercise this Warrant in advance of such Liquidation (and may condition such exercise on the consummation of such

Liquidation) by returning the Form of Notice of Exercise or Form of Net Issue Election Notice, as applicable, annexed hereto duly executed by or on behalf of such Registered Holder; or

(ii) in lieu of exercising this Warrant in advance of such Liquidation and receiving the consideration which the holder of the Shares issuable on such conversion of this Warrant would receive in connection with such Liquidation Event (the “Event Consideration”), surrender this Warrant for cancellation and receive, in redemption of and in exchange for this Warrant, an amount equal to the difference between (i) the Event Consideration with respect to the Shares for which this Warrant is exercisable immediately prior to the consummation of such Liquidation, minus (ii) the aggregate Exercise Price of the Shares for which this Warrant was exercisable immediately prior to the consummation of such Liquidation (the “Net Warrant Event Consideration”).

(d) If, in connection with such Liquidation, the price per share to be paid or distributed for or in respect of shares of the Company’s capital stock of the same class and series as the Shares is greater than the Exercise Price in effect at the time of immediately preceding the consummation of such Liquidation, such consideration is in the form of all cash and/or marketable securities and the Holder has not, prior to the time immediately preceding the consummation of such Liquidation, provided a Form of Notice of Exercise or Form of Net Issue Election Notice, then (x) the Holder shall be deemed to have elected to surrender this Warrant for cancellation and to receive, in redemption of and in exchange for this Warrant, an amount equal to the Net Warrant Event Consideration, and (y) this Warrant shall be terminated and of no further force immediately after the consummation of such Liquidation other than as evidence the Holder’s right to receive the Net Warrant Event Consideration. In lieu of the foregoing, the Company may provide in the definitive agreements governing such Liquidation that the Holder shall be entitled receive an amount equal to the Net Warrant Event Consideration in exchange for and upon surrender of this Warrant.”

2.3 Section 11 of the Warrants. Section 11 of the Warrants is hereby amended and restated in its entirety as follows:

“11. Amendments and Waivers. This Warrant may be amended and the observance of any other term of this Warrant may be waived (either generally or in a particular instance and either retroactively or prospectively), with the written consent of the Company and the holders of a majority in interest of the Shares issuable upon exercise of the Warrants issued pursuant to the Purchase Agreement; provided, that: (a) any such amendment, waiver or consent shall apply with equal force to all of the Warrants issued pursuant to the Purchase Agreement and the holders of such Warrants; (b) except for any amendment, waiver or consent which applies with equal force to all of the Warrants issued pursuant to the Purchase Agreement and the holders of such Warrants with respect to the operation of any of the provisions of such Warrants that require an adjustment to the Exercise Price and the number and kind of shares of stock or other securities or property deliverable upon the exercise of this Warrant upon the occurrence of any specified event, transaction, condition or circumstance, the written

consent of the Holder shall be required for any amendment, waiver or consent that would (i) increase the Exercise Price or decrease the number or type of shares of stock or other securities or property purchasable at the time of such amendment, waiver or consent upon exercise of this Warrant, or (ii) impair the Holder’s right to exercise this Warrant or the effect of Section 7.3; and (c) no consideration or other accommodation is paid or provided to any holder of such Warrants in connection with or related to such amendment, waiver or consent that is not also offered to the Holder. Any amendment or waiver effected in accordance with this Section 11 shall be binding upon Holder of this Warrant (and of any Shares into which this Warrant is exercisable), and each future holder of all such securities and the Company.”

2.4 New Section 14 Added to the Warrants. The following provision is added as a new Section 14 to the Warrants.

Any notice given in accordance with the foregoing clause (a) shall also specify, in the case of any such dividend, the date on which the holders of Shares shall be entitled thereto. Any notice given in accordance with the foregoing clause (b) shall also specify the date on which the holders of Shares shall be entitled to exchange their Shares for securities or other property deliverable upon such acquisition, reorganization, reclassification, dissolution, liquidation, winding-up, conversion or public offering, as the case may be.”
