Capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Asset Purchase Agreement.

                           2.            Authorization of Warrant Shares .

                           3.            Exercise of Warrant .

• •                      (a) Exercise of the purchase rights represented by this Warrant may be made at any time or times on or before the Termination Date by delivery to the Company of a duly executed original or facsimile copy of the Notice of Exercise Form annexed hereto (or such other office or agency of the Company as the Company may designate by notice in writing to the registered Holder at the address of such Holder appearing on the books of the Company) together with payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer to an account designated by the Company or cashier's check drawn on a United States bank; provided , however , that within 3 Trading Days after the date such Notice of Exercise is delivered to the Company, the Holder shall surrender this Warrant to the Company. For the purposes of this Warrant, " Trading Day " shall mean a day on which the principal United States market on which the Company's securities are traded is open for trading. Certificates for shares purchased hereunder shall be delivered to the Holder within 7 Trading Days after the date on which the Notice of Exercise shall have been delivered by original or facsimile copy and payment of the aggregate Exercise Price shall have been received by the Company as set forth above (" Warrant Share Delivery Date "); provided , however , that in the event the Warrant is not surrendered by the Holder and received by the Company within 3 Trading Days after the date on which the aggregate Exercise Price shall have been paid and the Notice of Exercise shall be delivered by facsimile copy, the Warrant Share Delivery Date shall be extended to the extent such 3 Trading Day period is exceeded. This Warrant shall be deemed to have been exercised on the date the Notice of Exercise is delivered to the Company and the aggregate Exercise Price shall have been paid. The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised by payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any, pursuant to Section 5 prior to the issuance of such shares, have been paid.

     

                         (b) If this Warrant shall have been exercised in part, the Company shall promptly deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

                           4.            No Fractional Shares or Scrip . No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to the difference between the fair market value of such fractional share as of the date of exercise and the Exercise Price of such fractional share.

                           5.            Charges, Taxes and Expenses . Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided , however , that in the event certificates for Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder; and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto and an opinion of counsel in form and substance reasonably satisfactory to the Company that the issuance to a person other than the Holder is permitted by applicable securities laws.

Subject to compliance with Section 7(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice.

     

                                   (a)The Company shall prepare, issue and deliver at its own expense (other than transfer taxes) the new Warrant or Warrants under this Section 7.

                           8.            No Rights as Shareholder until Exercise . This Warrant does not entitle the Holder to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof. The Company shall be entitled to treat the Holder of the Warrant as the owner in fact thereof for all purposes and shall not be bound to recognize any equitable or other claim to or interest in such Warrant on the part of any other person, and shall not be liable for any registration or transfer of Warrants which are registered or to be registered in the name of a fiduciary or the nominee of a fiduciary unless made with the actual knowledge that a fiduciary or nominee is committing a breach of trust in requesting such registration or transfer, or with the knowledge of such facts that its participation therein amounts to bad faith.

                           9.            Loss, Theft, Destruction or Mutilation of Warrant . The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, an indemnity and security reasonably satisfactory to it (which may include the posting of a bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

                           10.            Saturdays, Sundays, Holidays, etc . If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday, Sunday or a day that is not a Trading Day, then such action may be taken or such right may be exercised on the next succeeding day not a Saturday, Sunday or day that is not a Trading Day.

                           11.            Adjustments of Exercise Price and Number of Warrant Shares . The number and kind of securities purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time upon the happening of any of the following. In case the Company, at any time while the Warrant is outstanding, shall (i) pay a dividend in shares of Common Stock or make a distribution in shares of Common Stock to all holders of its outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine (including by way of reverse stock split) its outstanding shares of Common Stock into a smaller number of shares of Common Stock, or (iv) issue any shares of its capital stock in a reclassification of the Common Stock, then the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior thereto shall be adjusted so that the Holder shall be entitled to receive the kind and number of Warrant Shares or other securities of the Company which it would have owned or have been entitled to receive had such Warrant been exercised in advance thereof. Upon each such adjustment of the kind and number of Warrant Shares or other securities of the Company which are purchasable hereunder, the Holder shall thereafter be entitled to purchase the number of Warrant Shares or other securities resulting from such adjustment at an Exercise Price per Warrant Share or other security obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of Warrant Shares purchasable pursuant hereto immediately prior to such adjustment and dividing by the number of Warrant Shares or other securities of the Company that are purchasable pursuant hereto immediately after such adjustment. An adjustment made pursuant to this paragraph shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.
