The first Holder of this Warrant, by acceptance hereof, represents to the Company that it is acquiring the Warrants for investment and not with a view to the distribution thereof.

3. Exercise of Warrant

3.1. Exercise in Full. Subject to the provisions hereof, this Warrant may be exercised in full by the Holder hereof by surrender of this Warrant, with the form of subscription at the end hereof duly executed by such Holder, to the Company at its principal office accompanied by payment, in cash or by certified or official bank check payable to the order of the Company, in the amount obtained by multiplying the number of shares of Common Stock issuable upon exercise of this Warrant by the Purchase Price per share, after giving effect to all adjustments through the date of exercise.

3.2. Partial Exercise. Subject to the provisions hereof, this Warrant may be exercised in part by surrender of this Warrant in the manner and at the place provided in Section 3.1 except that the amount payable by the Holder upon any partial exercise shall be the amount obtained by multiplying (a) the number of shares of Common Stock (without giving effect to any adjustment therein) designated by the Holder in the subscription at the end hereof by (b) the Purchase Price per share. Upon any such partial exercise, the Company at its expense will forthwith issue and deliver to or upon the order of the Holder hereof a new Warrant or Warrants of like tenor, in the name of the Holder hereof or as such Holder (upon payment by such Holder of any applicable transfer taxes) may request, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock equal (without giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of such shares designated by the Holder in the subscription at the end hereof.

3.3. Exercise by Surrender of Warrant or Shares of Common Stock. In addition to the method of payment set forth in Sections 3.1 and 3.2 and in lieu of any cash payment required thereunder, the Holder(s) of the Warrants shall have the right at any time and from time to time to exercise the Warrants in full or in part by surrendering shares of Common Stock, this Warrant or other securities issued by the Company in the manner and at the place specified in Section 3.1 as payment of the aggregate Purchase Price per share for the Warrants to be exercised. The number of Warrants or shares of Common Stock to be surrendered in payment of the aggregate Purchase Price for the Warrants to be exercised shall be determined by multiplying the number of Warrants to be exercised by the Purchase Price per share, and then dividing the product thereof by an amount equal to the Market Price (as defined below) . The number of shares of Common Stock or such other securities to be surrendered in payment of the aggregate Purchase Price for the Warrants to be exercised shall be determined in accordance with the preceding sentence as if the other securities had been converted into Common Stock immediately prior to exercise or, in the case the Company has issued other securities which are not convertible into Common Stock, at the Market Price thereof.

3.4. Definition of Market Price. As used herein, the phrase "Market Price" at any date shall be deemed to be (i) if the principal trading market for such securities is an exchange, the average of the last reported sale prices per share for the last five previous trading days in which a sale was reported, as officially reported on any consolidated tape, (ii) if the principal market for such securities is the over-the-counter market, the average of the high bid prices per share on such trading days as set forth by Nasdaq or, (iii) if the security is not quoted on Nasdaq, the average of the high bid prices per share on such trading days as set forth in the National Quotation Bureau sheet listing such securities for such days. Notwithstanding the foregoing, if there is no reported closing price or high bid price, as the case may be, on any of the ten trading days preceding the event requiring a determination of Market Price hereunder, then the Market Price shall be determined in good faith by resolution of the Board of Directors of the Company, based on the best information available to it.

3.5. Company to Reaffirm Obligations. The Company will, at the time of any exercise of this Warrant, upon the request of the Holder hereof, acknowledge in writing its continuing obligation to afford to such Holder any rights (including, without limitation, any right to registration of the Underlying Securities) to which such Holder shall continue to be entitled after such exercise in accordance with the provisions of this Warrant, provided that if the Holder of this Warrant shall fail to make any such request, such failure shall not affect the continuing obligation of the Company to afford such Holder any such rights.

3.6. Certain Exercises. If an exercise of a Warrant or Warrants is to be made in connection with a registered public offering or sale of the Company, such exercise may, at the election of the Holder, be conditioned on the consummation of the public offering or sale of the Company, in which case such exercise shall not be deemed effective until the consummation of such transaction.

4. Delivery of Stock Certificates, etc., on Exercise. As soon as practicable after the exercise of this Warrant in full or in part, and in any event within three business days thereafter, the Company at its own expense (including the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder hereof, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct, a certificate or certificates for the number of fully paid and non-assessable shares of Common Stock or Other Securities to which such Holder shall be entitled upon such exercise, plus, in lieu of any fractional share to which such Holder would otherwise be entitled, cash equal to such fraction multiplied by the then current Market Price of one full share, together with any other stock or other securities and property (including cash, where applicable) to which such Holder is entitled upon such exercise pursuant to Section 5 or otherwise.

5. Adjustment for Dividends in Other Stock, Property, etc.; Reclassification, etc. In case at any time or from time to time after the Original Issue Date the holders of Common Stock (or, if applicable, Other Securities) shall have received, or (on or after the record date fixed for the determination of stockholders eligible to receive) shall have become entitled to receive, without payment therefor

(i) other or additional stock or other securities or property (other than cash) by way of dividend, or

(i) any cash paid or payable (including, without limitation, by way of dividend), or

(ii) other or additional stock or other securities or property (including cash) by way of spin-off, split-up, reclassification, recapitalization, combination of shares or similar corporate rearrangement,

then, and in each such case the Holder of this Warrant, upon the exercise hereof as provided in Section 3, shall be entitled to receive the amount of stock and other securities and property (including cash in the cases referred to in subdivisions (ii) and (iii) of this Section 5(a)) which such Holder would hold on the date of such exercise if on the Original Issue Date such Holder had been the Holder of record of the number of shares of Common Stock called for on the face of this Warrant and had thereafter, during the period from the Original Issue Date to and including the date of such exercise, retained such shares and all such other or additional stock and other securities and property (including cash in the cases referred to in subdivisions (ii) and (iii) of this Section 5(a)) receivable by such Holder as aforesaid during such period, giving effect to all adjustments called for during such period by Sections 6 hereof. If the number of shares of Common Stock outstanding at any time after the date hereof is decreased by a combination or reverse stock split of the outstanding shares of Common Stock, the Purchase Price per share shall be increased, and the number of shares of Common Stock purchasable under this Warrant shall be decreased in proportion to such decrease in outstanding shares of Common Stock.

6. Reorganization, Consolidation, Merger, etc. In case the Company after the Original Issue Date shall (a) effect a reorganization, (b) consolidate with or merge into any other person, or (c) transfer all or substantially all of its properties or assets to any other person under any plan or arrangement contemplating the dissolution of the Company, then, in each such case, the Holder of this Warrant, upon the exercise hereof as provided in Section 3 at any time after the consummation of such reorganization, consolidation or merger or the effective date of such dissolution, as the case may be, shall be entitled to receive (and the Company shall be entitled to deliver), in lieu of the Underlying Securities issuable upon such exercise prior to such consummation or such effective date, the stock and other securities and property (including cash) to which such Holder would have been entitled upon such consummation or in connection with such dissolution, as the case may be, if such Holder had so exercised this Warrant immediately prior thereto, all subject to further adjustment thereafter as provided in Sections 5 hereof. The Company shall not effect any such reorganization, consolidation, merger or sale, unless prior to or simultaneously with the consummation thereof, the successor corporation resulting from such consolidation or merger or the corporation purchasing such assets or the appropriate corporation or entity shall assume, by written instrument, the obligation to deliver to each Holder the shares of stock, cash, other securities or assets to which, in accordance with the foregoing provisions, each Holder may be entitled to and all other obligations of the Company under this Warrant. In any such case, if necessary, the provisions set forth in this Section 6 with respect to the rights thereafter of the Holders shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to any Other Securities or assets thereafter deliverable on the exercise of the Warrants.

7. Further Assurances. The Company will take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of stock upon the exercise of all Warrants from time to time outstanding.

8. Certificate as to Adjustments. In each case of any adjustment or readjustment in the shares of Common Stock (or Other Securities) issuable upon the exercise of the Warrants, the Company at its expense will promptly to compute such adjustment or readjustment in accordance with the terms of the Warrants and prepare a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, and the number of shares of Common Stock outstanding or deemed to be outstanding. The Company will forthwith mail a copy of each such certificate to each Holder.

9. Notices of Record Date, etc. In the event of

(a) any taking by the Company of a record of its stockholders for the purpose of determining the stockholders thereof who are entitled to receive any dividend or other distribution, or 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, or for the purpose of determining stockholders who are entitled to vote in connection with any proposed capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any transfer of all or substantially all the assets of the Company to or consolidation or merger of the Company with or into any other person, or

(b) any voluntary or involuntary dissolution, liquidation or winding-up of the Company, or
