The Holder hereof may exercise the Warrants, in whole or in part, by the surrender of the Warrant Certificate (with the exercise form attached hereto duly executed) at the principal office of the Issuer, and by the payment to the Issuer of an amount of consideration therefor equal to the Warrant Price in effect on the date of such exercise multiplied by the number of shares of Warrant Stock with respect to which the Warrant Certificate is then being exercised, payable at such Holder’s election (i) by certified or official bank check or by wire transfer to an account designated by the Issuer, (ii) by “cashless exercise” in accordance with the provisions of subsection (c) of this Section 2, or (iii) by a combination of the foregoing methods of payment selected by the Holder of the Warrant Certificate.

THIS WARRANT CERTIFICATE, THE WARRANTS, AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

3.          Adjustment of Warrant Price and Number of Shares Issuable Upon Exercise. The Warrant Price and the Warrant Share Number shall be subject to adjustment from time to time as set forth in this Section 3. The Issuer shall give the Holder notice of any event described below that requires an adjustment pursuant to this Section 3 in accordance with the notice provisions set forth in Section 4.

(a)          Recapitalization, Reorganization, Reclassification, Consolidation, Merger or Sale.

(i)          In case the Issuer after the Original Issue Date shall do any of the following (each, a “Triggering Event”): (A) consolidate or merge with or into any other Person and the Issuer shall not be the continuing or surviving corporation of such consolidation or merger, or (B) permit any other Person to consolidate with or merge into the Issuer and the Issuer shall be the continuing or surviving Person but, in connection with such consolidation or merger, any Capital Stock of the Issuer shall be changed into or exchanged for Securities of any other Person or cash or any other property, or (C) transfer all or substantially all of its properties or assets to any other Person, or (D) effect a capital reorganization or reclassification of its Capital Stock, then, and in the case of each such Triggering Event, proper provision shall be made to the Warrant Price and the number of shares of Warrant Stock that may be purchased upon exercise of this Warrant Certificate so that, upon the basis and the terms and in the manner provided in this Warrant Certificate the Holder of this Warrant Certificate shall be entitled upon the exercise hereof at any time after the consummation of such Triggering Event, to the extent the Warrants are not exercised prior to such Triggering Event, to receive at the Warrant Price as adjusted to take into account the consummation of such Triggering Event, in lieu of the Warrant Stock issuable upon such exercise of the Warrants prior to such Triggering Event, the Securities, cash and property to which such Holder would have been entitled upon the consummation of such Triggering Event if such Holder had exercised the rights represented by this Warrant Certificate immediately prior thereto subject to adjustments (subsequent to such corporate action) as nearly equivalent as possible to the adjustments provided for elsewhere in this Section 3. Upon the occurrence of a Triggering Event, the Issuer shall notify the Holder in writing of such Triggering Event and provide the calculations in determining the amount of issuable Securities, cash or property issuable upon exercise of the new warrant and the adjusted Warrant Price. Upon the Holder’s request, the continuing or surviving corporation as a result of such Triggering Event shall issue to the Holder a new warrant of like tenor evidencing the right to purchase the adjusted amount of Securities, cash or property and the adjusted Warrant Price pursuant to the terms and provisions of this Section 3(a)(i).

(ii) subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock, or

(iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock,

(c)          Issuance of Additional Shares below Warrant Price. If the Issuer issues, at any time after the Original Issue Date, any Additional Shares (as defined below) without consideration or for a consideration less than the Warrant Price in effect immediately prior to the issuance of such Additional Shares, the Warrant Price, as the case may be, in effect immediately prior to each such issuance shall automatically be adjusted as set forth in this Section 3(c),

4.           Notice of Adjustments.
