     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED PURSUANT TO THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS THERE IS A REGISTRATION STATEMENT THEN IN EFFECT COVERING SUCH SHARES OR AN EFFECTIVE EXEMPTION FROM SUCH REGISTRATION OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT UNDER THE CIRCUMSTANCES REGISTRATION IS NOT NECESSARY.

Provided, however, that if the issuance of the Shares pursuant to the exercise of this Warrant are subject to an effective registration statement pursuant to Section 5 of the Securities Act of 1933, as amended, certificates representing the Shares shall not bear any restrictive legend.

1.3 Limitations on Exercise.

     (a) Notwithstanding anything to the contrary contained herein, the number of Shares that may be acquired by the Warrantholder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such exercise (or other issuance), the total number of shares of common stock of the Company then beneficially owned by such Warrantholder and its affiliates and any other person or entity whose beneficial ownership of such common stock would be aggregated with the Warrantholder's for purposes of Section 13(d) of the Securities Exchange Act of 1934 (the “Exchange Act”), does not exceed 4.999% of the total number of issued and outstanding shares of common stock of the Company (including for such purpose the shares of common stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. This provision shall not restrict the number of shares of common stock which a Warrantholder may receive or beneficially own in order to determine the amount of securities or other consideration that such Warrantholder may receive in the event of a transaction contemplated by Section 2.1 of this Warrant. By written notice to the Company, a Warrantholder may waive the provisions of this Section 1.3(a) as to itself but any such waiver will not be effective until the 61st day after delivery thereof and such waiver shall have no effect on any other person or entity.

     (b) Notwithstanding anything to the contrary contained herein, the number of Shares that may be acquired by the Warrantholder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such exercise (or other issuance), the total number of shares of common stock of the Company then beneficially owned by such Warrantholder and its affiliates and any other person or entity whose beneficial ownership of such common stock would be aggregated with the Warrantholder's for purposes of Section 13(d) of the Exchange Act, does not exceed 9.999% of the total number of issued and outstanding shares of common stock of the Company (including for such purpose the shares of common stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. This provision shall not restrict the number of shares of Common Stock which a Warrantholder may receive or beneficially own in order to determine the amount of securities or other consideration that such Warrantholder may receive in the event of a transaction contemplated by Section 2.1 of this Warrant. This restriction may not be waived.

     2. Reclassification, Consolidation or Merger.

     2.1 In the event that the outstanding Shares are hereafter changed by reason of reorganization, merger, consolidation, recapitalization, reclassification, stock split-up, combination or exchange of Shares and the like, or dividends payable in Shares, an appropriate adjustment shall be made by the Board of Directors of the Company in the number of Shares and price per Share subject to this Warrant Certificate. If the Company shall be reorganized, consolidated, or merged with another corporation, or if all or substantially all of the assets of the Company shall be sold or exchanged, the Warrantholder shall at the time of issuance of the stock under such a corporate event, be entitled to receive upon the exercise of the vested Warrants evidenced by this Warrant Certificate the same number and kind of shares of stock or the same amount of property, cash or securities as he would have been entitled to receive upon the occurrence of any such corporate event as if he had been, immediately prior to such event, the holder of the number of Shares so exercised.

2

     2.2 Any adjustment under this Paragraph 2 in the number of Shares subject to this Warrant Certificate shall apply proportionately to only the unexercised portion hereunder and shall not have any retroactive effect with respect to Warrants theretofore exercised. If fractions of a Share would result from any such adjustment, the adjustment shall be revised to the next lower whole number of Shares.

     2.3 No adjustment of the exercise price shall be made if the amount of such adjustment shall be less than $.01 per Share, but in such case any adjustment that would otherwise be required then to be made, shall be carried forward and shall be made at the time and together with the next subsequent adjustment which, together with any adjustment so carried forward, shall amount to no less than $.01 per share.

     2.4 No fractional shares of common stock shall be issued upon the exercise of any Warrants evidenced hereby, but in lieu thereof the number of shares of common stock that are issuable upon any exercise shall be rounded up or down to the nearest whole share.

     2.5 When any adjustment is required to be made in the exercise price or number of Shares subject to this Warrant Certificate, initial or adjusted, the Company shall within sixty (60) days after the date when the circumstances giving rise to the adjustment occurred mail to the Warrantholder a statement describing in reasonable detail any method used in calculating such adjustment.

     3. Prior Notice as to Certain Events.

     The Company shall mail to Warrantholder not less than ten (10) days prior to the date on which (a) a record will be taken for the purpose of determining the holders of Capital Stock entitled to subscription rights, or (b) a record will be taken (or in lieu thereof, the transfer books will be closed) for the purpose of determining the holders of Capital Stock entitled to notice of and to vote at the meeting of stockholders at which any consolidation, merger, dissolution, liquidation, winding up or sale of the Company shall be considered and acted upon.

     4. Reservation and Issuance of Shares.

     4.1 The Company covenants and agrees that all Shares which may be issued upon the exercise of the rights represented by this Warrant Certificate will be duly authorized, legally issued and when paid for in accordance with the terms hereof, fully paid and non-assessable, and free from all liens and charges with respect to the issue thereof to the Warrantholder.
