1. Registration, etc.The Holder shall have the rights to registration of Underlying Securities issuable upon exercise of the Warrants that are set forth in the Registration Rights Agreement, dated the Original Issue Date, between the Company and the Holder (the"Registration Rights Agreement").
2. Sale or Exercise Without Registration.If, at the time of any exercise, transfer or surrender for exchange of a Warrant or of Underlying Securities previously issued upon the exercise of Warrants, such Warrant or Underlying Securities shall not be registered under the Securities Act, the Company may require, as a condition of allowing such exercise, transfer or exchange, that the Holder or transferee of such Warrant or Underlying Securities, as the case may be, furnish to the Company an opinion of counsel, reasonably satisfactory to the Company, to the effect that such exercise, transfer or exchange may be made without registration under the Securities Act, provided that the disposition thereof shall at all times be within the control of such Holder or transferee, as the case may be, and provided further that nothing contained in this Section 2 shall relieve the Company from complying with any request for registration pursuant to the Registration Rights Agreement. 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
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.
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. 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.
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.
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.
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.
5. Subdivisions, Combinations and Other Issuances. If the Company shall at any time prior to the expiration of this Warrant subdivide the Underlying Securities, by split-up or otherwise, or combine its Underlying Securities, or issue additional shares of its Underlying Securities as a dividend, the number of Underlying Securities issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination. Appropriate adjustments shall also be made to the Purchase Price payable per share, but the aggregate Purchase Price payable for the total number of Underlying Securities purchasable under this Warrant (as adjusted) shall remain the same. Any adjustment under this Section 5 shall become effective at the close of business on the date the subdivision or combination becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of such dividend.
6. Reclassification, Reorganization and Consolidation.In case of any reclassification, capital reorganization, or change in the capital stock of the Company (other than as a result of a subdivision, combination, or stock dividend provided for in Section 5 above), then the Company shall make appropriate provision so that the holder of this Warrant shall have the right at any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock and other securities and property receivable in connection with such reclassification, reorganization, or change by a holder of the same number of Underlying Securities as were purchasable by the holder of this Warrant immediately prior to such reclassification, reorganization, or change In any such case appropriate provisions shall be made with respect to the rights and interest of the holder of this Warrant so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities and property deliverable upon exercise hereof, and appropriate adjustments shall be made to the purchase price per share payable hereunder, provided the aggregate purchase price shall remain the same.
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 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. Rights of Stockholders.No holder of this Warrant shall be entitled, as a Warrant holder, to vote or receive dividends or be deemed the holder of any Underlying Securities, nor shall anything contained herein be construed to confer upon the holder of this Warrant, as such, any of the rights of a stockholder of the Company orany right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive subscription rights or otherwise until the Warrant has been exercised and the Underlying Securities purchasable upon exercise hereof shall become deliverable as provided herein.
10. Reservation of Stock, etc., Issuable on Exercise of Warrants.The Company will at all times reserve and keep available, solely for issuance and delivery upon the exercise of the Warrants, all shares of Common Stock (or Other Securities) from time to time issuable upon the exercise of the Warrants.
11. Listing on Securities Exchanges.In furtherance and not in limitation of any other provision of this Warrant, if the Company at any time shall list any Common Stock on any national securities exchange and shall register such Common Stock under the Exchange Act, the Company will, at its expense, simultaneously list on such exchange or Nasdaq, upon official notice of issuance upon the exercise of the Warrants, and maintain such listing of all shares of Common Stock from time to time issuable upon the exercise of the Warrants; and the Company will so list on any national securities exchange or Nasdaq, will so register and will maintain such listing of, any Other Securities if and at the time that any securities of like class or similar type shall be listed on such national securities exchange or Nasdaq by the Company.

Exchange of Warrants.Subject to the provisions of Section 2 hereof, upon surrender for exchange of any Warrant, properly endorsed, to the Company, as soon as practicable (and in any event within three business days) the Company at its own expense will issue and deliver to or upon the order of the Holder thereof a new Warrant or Warrants of like tenor, in the name of such Holder or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock called for on the face or faces of the Warrant or Warrants so surrendered.
13. Replacement of Warrants.Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of any Warrant and, in the case of any such loss, theft or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, upon surrender and cancellation of such Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.
14. Remedies.The Company stipulates that the remedies at law of the Holder of this Warrant in the event of any default or threatened default by the Company in the performance of or compliance with any of the terms of this Warrant are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise.
