"EXERCISE PERIOD" shall mean that period beginning six months after the date of this Warrant and continuing until the expiration of the five-year period thereafter. "EXERCISE PRICE" as of the date hereof shall mean $8.60 per share, as may be adjusted from time to time pursuant to Section 6 hereof. "PER SHARE WARRANT VALUE" shall mean the difference resulting from subtracting the Exercise Price from the Closing Price on the Trading Day immediately preceding the Exercise Date.

"WARRANT SHARES" shall mean those shares of Common Stock received upon exercise of this Warrant. Section 2. EXERCISE. (a) METHOD OF EXERCISE. This Warrant may be exercised in whole or in part (but not as to a fractional share of Common Stock), at any time and from time to time during the Exercise Period, by the Warrant Holder by (i) surrender of this Warrant, with the form of exercise attached hereto as Exhibit A completed and duly executed by the Warrant Holder (the "EXERCISE NOTICE"), to the Company as set forth in Section 14 hereof, accompanied by payment of the Exercise Price multiplied by the number of shares of Common Stock for which this Warrant is being exercised (the "AGGREGATE EXERCISE PRICE") or (ii) telecopying an executed and completed Exercise Notice to the Company and delivering to the Company within five (5) business days thereafter the original Exercise Notice, this Warrant and the Aggregate Exercise Price. Each date on which an Exercise Notice is received by the Company in accordance with clause (i) and each date on which the Exercise Notice is telecopied to the Company in accordance with clause (ii) above shall be deemed an "EXERCISE DATE." (b) PAYMENT OF AGGREGATE EXERCISE PRICE. Subject to paragraph (c) below, payment of the Aggregate Exercise Price shall be made by wire transfer of immediately available funds to an account designated by the Company. If the amount of the payment received by the Company is less than the Aggregate Exercise Price, the Warrant Holder will be notified of the deficiency and shall make payment in that amount within three (3) Trading Days. In the event the payment exceeds the Aggregate Exercise Price, the Company will refund the excess to the Warrant Holder within five (5) Trading Days of receipt. (c) CASHLESS EXERCISE. In the event that the Warrant Shares to be received by the Warrant Holder upon exercise of the Warrant may not be resold pursuant to an effective registration statement or an exemption to the registration requirements of the Securities Act of 1933, as amended, and applicable state laws, the Warrant Holder may, as an alternative to payment of the Aggregate Exercise Price upon exercise in accordance with paragraph (b) above, elect to effect a cashless exercise by so indicating on the Exercise Notice and including a calculation of the number of shares of Common Stock to be issued upon such exercise in accordance with the terms hereof (a "CASHLESS EXERCISE"). If a registration statement on Form S-1 under the Securities Act of 2 1933, as amended, or such other form as deemed appropriate by counsel to the Company for the registration for the resale by the Warrant Holder of (x) the shares of Common Stock of the Company that may be purchased under the Agreement, (y) the Warrant Shares, or (z) any securities issued or issuable with respect to any of the foregoing by way of exchange, stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization or otherwise, has been declared effective by the SEC and remains effective, the Company may permit or require the Warrant Holder elect to effect a Cashless Exercise. In the event of a Cashless Exercise, the Warrant Holder shall receive that number of shares of Common Stock determined by (i) multiplying the number of Warrant Shares for which this Warrant is being exercised by the Per Share Warrant Value and (ii) dividing the product by the Closing Price on the Trading Day immediately preceding the Exercise Date, rounded to the nearest whole share. The Company shall cancel the total number of Warrant Shares equal to the excess of the number of the Warrant Shares for which this Warrant is being exercised over the number of Warrant Shares to be received by the Warrant Holder pursuant to such Cashless Exercise. (d) REPLACEMENT WARRANT. In the event that the Warrant is not exercised in full, the number of Warrant Shares shall be reduced by the number of such Warrant Shares for which this Warrant is exercised, and the Company, at its expense, shall forthwith issue and deliver to or upon the order of the Warrant Holder a new Warrant of like tenor in the name of the Warrant Holder, reflecting such adjusted number of Warrant Shares. Section 3. TEN PERCENT LIMITATION. The Warrant Holder may not exercise this Warrant such that the number of Warrant Shares to be received pursuant to such exercise aggregated with all other shares of Common Stock then owned by the Warrant Holder beneficially or deemed beneficially owned by the Warrant Holder would result in the Warrant Holder owning more than 9.9% of all of such Common Stock as would be outstanding on such Exercise Date, as determined in accordance with Section 13(d) of the Exchange Act of 1934 and the rules and regulations promulgated thereunder. Section 4. DELIVERY OF WARRANT SHARES. (a) Subject to the terms and conditions of this Warrant, as soon as practicable after the exercise of this Warrant in full or in part, and in any event within ten (10) Trading Days thereafter, the Company at its expense (including, without limitation, the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Warrant Holder, or as the Warrant Holder may lawfully direct, a certificate or certificates for, or make deposit with the Depositary Trust Company via book-entry of, the number of validly issued, fully paid and non-assessable Warrant Shares to which the Warrant Holder shall be entitled on such exercise, together with any other stock or other securities or property (including cash, where applicable) to which the Warrant Holder is entitled upon such exercise in accordance with the provisions hereof. (b) This Warrant may not be exercised as to fractional shares of Common Stock. In the event that the exercise of this Warrant, in full or in part, would result in the issuance of any fractional share of Common Stock, then in such event the Warrant Holder shall receive the number of shares rounded to the nearest whole share. 3 Section 5. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY. (a) The Warrant Shares, when issued in accordance with the terms hereof, will be duly authorized and, when paid for or issued in accordance with the terms hereof, shall be validly issued, fully paid and non-assessable. (b) The Company shall take all commercially reasonable action and proceedings as may be required and permitted by applicable law, rule and regulation for the legal and valid issuance of this Warrant and the Warrant Shares to the Warrant Holder. (c) The Company has authorized and reserved for issuance to the Warrant Holder the requisite number of shares of Common Stock to be issued pursuant to this Warrant. The Company shall at all times reserve and keep available, solely for issuance and delivery as Warrant Shares hereunder, such shares of Common Stock as shall from time to time be issuable as Warrant Shares. (d) From the date hereof through the last date on which this Warrant is exercisable, the Company shall take all steps commercially reasonable to ensure that the Common Stock remains listed or quoted on the Principal Market. Section 6. ADJUSTMENT OF THE EXERCISE PRICE. The Exercise Price and, accordingly, the number of Warrant Shares issuable upon exercise of the Warrant, shall be subject to adjustment from time to time upon the happening of certain events as follows: (a) RECLASSIFICATION, CONSOLIDATION, MERGER, MANDATORY SHARE EXCHANGE, SALE OR TRANSFER. (i) Upon occurrence of any of the events specified in subsection (a)(ii) below (the "ADJUSTMENT EVENTS") while this Warrant is unexpired and not exercised in full, the Warrant Holder may in its sole discretion require the Company, or any successor or purchasing corporation, as the case may be, without payment of any additional consideration therefor, to execute and deliver to the Warrant Holder a new Warrant providing that the Warrant Holder shall have the right to exercise such new Warrant (upon terms not less favorable to the Warrant Holder than those then applicable to this Warrant) and to receive upon such exercise, in lieu of each share of Common Stock theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money or property receivable upon such Adjustment Event by the holder of one share of Common Stock issuable upon exercise of this Warrant had this Warrant been exercised immediately prior to such Adjustment Event. Such new Warrant shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 6. (ii) The Adjustment Events shall be (1) any reclassification or change of Common Stock (other than a change in par value, as a result of a subdivision or combination of Common Stock or in connection with an Excluded Merger or Sale), (2) any consolidation, merger or mandatory share exchange of the Company with or into another corporation (other than a merger or mandatory share exchange with another corporation in which the Company is a continuing corporation and which does not result in any reclassification or change other than a change in par value or as a result of a subdivision or combination of Common Stock), other than (each of the following referred to as an "EXCLUDED MERGER OR SALE") a transaction involving (A) sale of all or substantially all of the assets of the Company, (B) any merger, consolidation or similar transaction 4 where the consideration payable to the shareholders of the Company by the acquiring Person consists substantially entirely of cash, or where the acquiring Person does not agree to assume the obligations of the Company under outstanding warrants (including this Warrant). In the event of an Excluded Merger or Sale transaction, if the surviving, successor or purchasing Person does not agree to assume the obligations under this Warrant, then the Company shall deliver a notice to the Warrant Holder at least 10 days before the consummation of such Excluded Merger or Sale, the Warrant Holder may exercise this Warrant at any time before the consummation of such Excluded Merger or Sale (and such exercise may be made contingent upon the consummation of such Excluded Merger or Sale), and any portion of this Warrant that has not been exercised before consummation of such Excluded Merger or Sale shall terminate and expire, and shall no longer be outstanding. (b) SUBDIVISION OR COMBINATION OF SHARES. If the Company, at any time while this Warrant is unexpired and not exercised in full, shall subdivide its Common Stock, the Exercise Price shall be proportionately reduced as of the effective date of such subdivision, or, if the Company shall take a record of holders of its Common Stock for the purpose of so subdividing, as of such record date, whichever is earlier. If the Company, at any time while this Warrant is unexpired and not exercised in full, shall combine its Common Stock, the Exercise Price shall be proportionately increased as of the effective date of such combination, or, if the Company shall take a record of holders of its Common Stock for the purpose of so combining, as of such record date, whichever is earlier. (c) STOCK DIVIDENDS. If the Company, at any time while this Warrant is unexpired and not exercised in full, shall pay a dividend or other distribution in shares of Common Stock to all holders of Common Stock, then the Exercise Price shall be adjusted, as of the date the Company shall take a record of the holders of its Common Stock for the purpose of receiving such dividend or other distribution (or if no such record is taken, as at the date of such payment or other distribution), to that price determined by multiplying the Exercise Price in effect immediately prior to such payment or other distribution by a fraction: 1. the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and 2. the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution. The provisions of this subsection (c) shall not apply under any of the circumstances for which an adjustment is provided in subsections (a) or (b). (d) LIQUIDATING DIVIDENDS, ETC. If the Company, at any time while this Warrant is unexpired and not exercised in full, makes a distribution of its assets or evidences of indebtedness to all holders of its Common Stock as a dividend in liquidation or by way of return of capital or other than as a dividend payable out of earnings or surplus legally available for dividends under applicable law or any distribution to such holders made in respect of the sale of all or substantially all of the Company's assets (other than under the circumstances provided for in the foregoing subsections (a) through (c)), then the Warrant Holder shall be entitled to receive upon exercise of this Warrant in addition to the Warrant Shares receivable in connection therewith, and without payment of any consideration other than the Exercise Price, the kind and amount of such distribution per share of Common Stock multiplied by the number of Warrant Shares that, on the record date for such distribution, are issuable upon 5 such exercise of the Warrant (with no further adjustment being made following any event which causes a subsequent adjustment in the number of Warrant Shares issuable), and an appropriate provision therefor shall be made a part of any such distribution. The value of a distribution that is paid in other than cash shall be determined in good faith by the Board of Directors of the Company. Notwithstanding the foregoing, in the event of a proposed dividend in liquidation or distribution to the shareholders made in respect of the sale of all or substantially all of the Company's assets, the Company shall deliver a notice to the Warrant Holder at least 10 days before the consummation of such event, the Warrant Holder may exercise this Warrant at any time before the consummation of such event (and such exercise may be made contingent upon the consummation of such event), and any portion of this Warrant that has not been exercised before consummation of such event shall terminate and expire, and shall no longer be outstanding. (e) Upon the expiration of any rights, options, warrants or conversion privileges with respect to the issuance of which an adjustment to the Exercise Price or number of Warrant Shares had been made, if such shall not have been exercised, the Exercise Price or number of Warrant Shares purchasable upon exercise of this Warrant, to the extent this Warrant has not then been exercised, shall, upon such expiration, be readjusted and shall thereafter be such as they would have been had they been originally adjusted (or had the original adjustment not been required, as the case may be) on the basis of (i) the fact that Common Stock, if any, actually issued or sold upon the exercise of such rights, options, warrants or conversion privileges and (ii) the fact that such shares of Common Stock, if any, were issued or sold for the consideration actually received by the Company upon such exercise plus the consideration, if any, actually received by the Company for the issuance, sale or grant of all such rights, options, warrants or conversion privileges whether or not exercised; provided, however, that no such readjustment shall have the effect of decreasing the number of Warrant Shares purchasable upon exercise of this Warrant by an amount in excess of the amount of the adjustment initially made in respect of the issuance, sale or grant of such rights, options, warrants or conversion privileges. Section 7. NOTICE OF ADJUSTMENTS. (a) Whenever the Exercise Price or number of Warrant Shares shall be adjusted pursuant to Section 6 hereof, the Company shall promptly prepare a certificate signed by its President or Chief Financial Officer setting forth in reasonable detail the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a description of the basis on which the Company's Board of Directors made any determination hereunder), and the Exercise Price and number of Warrant Shares purchasable at that Exercise Price after giving effect to such adjustment, and shall promptly cause copies of such certificate to be sent by overnight courier to the Warrant Holder. In the event the Company shall, at a time while the Warrant is unexpired and not exercised in full, take any action that pursuant to subsections (a) through (c) of Section 6 may result in an adjustment of the Exercise Price, the Company shall give to the Warrant Holder at its last address known to the Company written notice of such action ten (10) days in advance of its effective date in order to afford to the Warrant Holder an opportunity to exercise the Warrant prior to such action becoming effective. (b) Notwithstanding Section 7(a), no adjustment in the Exercise Price (or in the number of Warrant Shares) shall be required unless such adjustment would require a change in the Exercise Price of a least $0.05 per share of Common Stock, provided, however, that any adjustment which by reason of this Section 6.2(b) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 7 shall be made to the nearest cent. 6 Section 8. NO IMPAIRMENT. The Company will not, by amendment of its Certificate of Incorporation, as amended, or Bylaws or through any reorganization, transfer of assets, consolidation, merger, dissolution or issue or sale of securities, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Warrant Holder against impairment. Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any Warrant Shares above the amount payable therefor on such exercise, and (b) will take all such action as may be reasonably 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. Section 9. RIGHTS AS STOCKHOLDER. Except as set forth in Section 6 above, prior to exercise of this Warrant, the Warrant Holder shall not be entitled to any rights as a stockholder of the Company with respect to the Warrant Shares, including (without limitation) the right to vote such shares, receive dividends or other distributions thereon or be notified of stockholder meetings. However, in the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, the Company shall mail to each Warrant Holder, at least ten (10) days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right. Section 10. REPLACEMENT OF WARRANT. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of the Warrant and, in the case of any such loss, theft or destruction of the Warrant, upon delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of such Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor. Section 11. CHOICE OF LAW. This Warrant shall be construed under the laws of the State of New York. Section 12. ENTIRE AGREEMENT; AMENDMENTS. Except for any written instrument concurrent or subsequent to the date hereof executed by the Company and the Investor, this Warrant and the Agreement contain the entire understanding of the parties with respect to the matters covered hereby and thereby.
