Section 2.01. Method of Exercise.

(a) Subject to and upon the terms and conditions set forth in this Amended and Restated Common Stock Purchase Warrant (this “Warrant”), the Holder may exercise this Warrant, in whole or in part with respect to any Warrant Shares, at any time and from time to time prior to 5:00 P.M., New York City time, on the Expiration Date, by presentation and surrender of this Warrant to the Company at its principal office, together with (x) a properly completed and duly executed subscription form, in the form attached hereto as Exhibit A, which subscription form shall specify the number of Warrant Shares for which this Warrant is then being exercised and the Person to whom the Warrant Shares shall be issued, who may be the Holder or an Affiliate of the Holder, (y) payment of the aggregate Exercise Price payable hereunder in respect of the number of Warrant Shares being purchased upon exercise of this Warrant, and (z) if applicable, the payment of any transfer taxes required to be paid by the Holder pursuant to Section 2.07. Payment of such aggregate Exercise Price shall be made in cash, by money order, certified or bank cashier’s check or wire transfer (in each case in lawful currency of the United States of America) or through a “cashless exercise” in the manner provided in Section 2.01(b).

(b) In lieu of making payment in the manner provided in Section 2.01(a) of all or any portion of the aggregate Exercise Price payable in respect of the number of Warrant Shares for which this Warrant is being exercised, the Holder may pay all or such portion of such aggregate Exercise Price on a “cashless” basis by electing not to receive all of such Warrant Shares otherwise issuable upon such exercise but only to receive that number of such Warrant Shares as shall be determined in accordance with the following formula:

X = Y(A-B)

        A

The Holder may elect to make payment of all or any portion of such aggregate Exercise Price pursuant to, and in the manner set forth in, this Section 2.01(b) by surrendering this Warrant to the Company at its principal office, together with (x) a properly completed and duly executed net issue exercise election, in the form attached hereto as Exhibit B, which net issue exercise election shall specify the number of Warrant Shares for which this Warrant is then being exercised (which shall include the number of Warrant Shares to be surrendered as payment therefor) and the Person to whom the Warrant Shares shall be issued, who may be the Holder or an Affiliate of the Holder, (y) if not already a party thereto, an instrument of accession to the Stockholder Agreement and the Registration Rights Agreement, in each case, dated as of the Initial Exercise Date, in substantially the form reasonably requested by the Company, and (z) if applicable, the payment of any transfer taxes required to be paid by the Holder pursuant to Section 2.07.

Section 2.04. Shares To Be Fully Paid and Nonassessable. All Warrant Shares issued upon the exercise of this Warrant shall be validly issued, fully paid and nonassessable, free of all liens, taxes, charges and other encumbrances or restrictions on sale (other than those set forth herein, including restrictions under the Stockholder Agreement and the Registration Rights Agreement) and free and clear of all preemptive rights and will be issued in compliance with all applicable federal and state securities laws.

Section 2.05. Fractional Shares. No fractional Warrant Shares or scrip representing fractional Warrant Shares shall be issued upon the exercise of this Warrant. With respect to any fraction of a Warrant Share called for upon any exercise hereof, the Company shall make a cash payment to the Holder as set forth in Section 2.03.

Moreover, the Company shall, at the time of any exercise of this Warrant, upon the request of the Holder, acknowledge in writing its continuing obligation to afford to the Holder any rights to which the Holder shall continue to be entitled after such exercise in accordance with the provisions of this Warrant; provided, however, that if the Holder shall fail to make any such request, such failure shall not affect the continuing obligation of the Company to afford to the Holder any such rights.

Section 2.07. Payment of Taxes and Expenses. The Holder shall be required to pay any tax which may be payable in respect of any transfer involved in the issuance of, and the preparation and delivery of certificates (if applicable) representing, (i) any Warrant Shares purchased upon exercise of this Warrant and issued in a name other than that of the Holders and/or (ii) new or replacement warrants in a name other than that of the Holder.

AND COMBINATIONS.

ARTICLE X

INVESTMENT REPRESENTATIONS

Section 10.01. Investment Representations.

(a) This Warrant and the Warrant Shares to be acquired by the Holder as contemplated hereby are being acquired for the Holder’s own account, for investment, and not with a view to the resale or distribution thereof or with the present intention of distributing or selling any of such securities. The Holder understands that such securities have not been registered under the Securities Act of 1933, on the ground that the offer and sale of such securities by the Company to the Holder are exempt from the registration requirements of the Securities Act under Section 4(2) thereof as a transaction not involving any public offering of such securities. The Holder understands that the Company’s reliance on such exemption is predicated in part on the representations of the Holder contained herein.

(b) The Holder understands that it may bear the economic risk of investment in the Warrant and the Warrant Shares to be acquired by it hereunder for an indefinite period of time because such securities have not been registered under the Securities Act, and therefore may not be sold unless they are subsequently registered under the Securities Act or an exemption from such registration is available.

(c) The Holder acknowledges and agrees that this Warrant and each certificate representing Warrant Shares acquired by it hereunder shall bear appropriate restrictive legends referring to the restrictions on transfer applicable to such securities. Holder is an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act. Holder has such knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risk of its investment in the Company. Holder has been furnished with all information and materials it has requested concerning the Company.

Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any Warrant Shares receivable upon the exercise of this Warrant above the amount payable therefor on such exercise, and (b) will take all action that may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares on the exercise of this Warrant.

The Holder shall not be entitled to vote or to receive dividends or to be deemed the holder of Warrant Shares that may at any time be issuable upon exercise of this Warrant for any purpose whatsoever, nor shall anything contained herein be construed to confer upon the Holder any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance or reclassification of stock, change of par value or change of stock to no par value, consolidation, merger or conveyance or otherwise), or to receive notice of meetings (except to the extent otherwise provided in this Warrant), or to receive dividends or subscription rights, until the Holder shall have exercised the Warrant in accordance with the provisions hereof.
