WARRANT CERTIFICATES. The warrant certificates (the "Warrant Certificates") delivered and to be delivered pursuant to this Agreement shall be in the form set forth in Exhibit A attached hereto and made a part hereof, with such appropriate insertions, omissions, substitutions, and other variations as required or permitted by this Agreement. 3. EXERCISE OF WARRANT.

The Warrant Certificates and the certificates representing the Common Stock (and/or other securities, property or rights issuable upon the exercise of the Warrants) shall be executed on behalf of the Company by the manual or facsimile signature of the then present Chairman or Vice Chairman of the Board of Directors or President or Vice President of the Company under its corporate seal reproduced thereon, attested to by the manual or facsimile signature of the then present Secretary or Assistant Secretary of the Company. Warrant Certificates shall be dated the date of execution by the Company upon initial issuance, division, exchange, substitution or transfer. 5. RESTRICTION ON TRANSFER OF WARRANTS.

EXERCISE PRICE. 6.1 INITIAL AND ADJUSTED EXERCISE PRICE. Except as otherwise provided in Section 8 hereof, the initial exercise price of each Warrant shall be $9.60 per share of Common Stock. The adjusted exercise price shall be the price which shall result from time to time from any and all adjustments of the initial exercise price in accordance with the provisions of Section 8 hereof. 6.2 EXERCISE PRICE.

The Registration Rights Agreement is incorporated herein by reference and made a part hereof, and it is expressly agreed that the Warrant Securities shall have all of the rights and privileges of the shares of Common Stock which are the subject of the Registration Rights Agreement, and that the Holders of Warrants are third party beneficiaries of the Registration Rights Agreement. 8. ADJUSTMENTS TO EXERCISE PRICE AND NUMBER OF SECURITIES. 8.1 SUBDIVISION AND COMBINATION. In case the Company shall at any time subdivide or combine the outstanding shares of Common Stock, the Exercise Price shall forthwith be proportionately decreased in the case of subdivision or increased in the case of combination. 8.2 STOCK DIVIDENDS AND DISTRIBUTIONS. In case the Company shall pay a dividend in, or make a distribution of, shares of Common Stock or of the Company's capital stock convertible into Common Stock, the Exercise Price shall forthwith be proportionately decreased. An adjustment made pursuant to this Section 8.2 shall be made as of the record date for the subject stock dividend or distribution. 8.3 ADJUSTMENT IN NUMBER OF SECURITIES. Upon each adjustment of the Exercise Price pursuant to the provisions of this Section 8, the number of Securities issuable upon the exercise at the adjusted exercise price of each Warrant shall be adjusted to the nearest full amount by multiplying a number equal to the Exercise Price in effect immediately prior to such adjustment by the number of Warrant Shares issuable upon exercise of the Warrants immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price. 3 8.4 DEFINITION OF COMMON STOCK. For the purpose of this Agreement, the term "Common Stock" shall mean (i) the class of stock designated as Common Stock in the Certificate of Incorporation of the Company as may be amended as of the date hereof, or (ii) any other class of stock resulting from successive changes or reclassifications of such Common Stock consisting solely of changes in par value, or from par value to no par value, or from no par value to par value. 8.5 MERGER OR CONSOLIDATION. In case of any consolidation of the Company with, or merger of the Company with, or merger of the Company into, another corporation (other than a consolidation or merger which does not result in any reclassification or change of the outstanding Common Stock), the corporation formed by such consolidation or merger shall execute and deliver to the Holder a supplemental warrant agreement providing that the holder of each Warrant then outstanding or to be outstanding shall have the right thereafter (until the expiration of such Warrant) to receive, upon exercise of such warrant, the kind and amount of shares of stock and other securities and property receivable upon such consolidation or merger, by a holder of the number of shares of Common Stock of the Company for which such warrant might have been exercised immediately prior to such consolidation, merger, sale or transfer. Such supplemental warrant agreement shall provide for adjustments which shall be identical to the adjustments provided in Section 8. The above provision of this subsection shall similarly apply to successive consolidations or mergers. 8.6 NO ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES. No adjustment of the Exercise Price shall be made: (a) Upon the issuance or sale of the Warrants or the shares of Common Stock issuable upon the exercise of the Warrants; or (b) If the amount of said adjustment shall be less than two cents (2(cent)) per Warrant Share, provided, however, that 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 of and together with the next subsequent adjustment which, together with any adjustment so carried forward, shall amount to at least two cents (2(cent)) per Warrant Share. 9. EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES. Each Warrant Certificate is exchangeable without expense, upon the surrender thereof by the registered Holder at the principal executive office of the Company, for a new Warrant Certificate of like tenor and date representing in the aggregate the right to purchase the same number of Warrant Shares in such denominations as shall be designated by the Holder thereof at the time of such surrender. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of any Warrant Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation 4 of the Warrants, if mutilated, the Company will make and deliver a new Warrant Certificate of like tenor, in lieu thereof. 10. ELIMINATION OF FRACTIONAL INTERESTS. The Company shall not be required to issue certificates representing fractions of shares of Common Stock upon the exercise of the Warrants, nor shall it be required to issue scrip or pay cash in lieu of fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up to the nearest whole number of shares of Common Stock or other securities, properties or rights. 11. RESERVATION AND LISTING OF SECURITIES. The Company shall at all times reserve and keep available out of its authorized shares of Common Stock, solely for the purpose of issuance upon the exercise of the Warrants, such number of shares of Common Stock or other securities, properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Warrants and payment of the Exercise Price therefor, all shares of Common Stock and other securities issuable upon such exercise shall be duly and validly issued, fully paid, non-assessable and not subject to the preemptive rights of any stockholder. As long as the Warrants shall be outstanding, the Company shall use its best efforts to cause all shares of Common Stock issuable upon the exercise of the Warrants to be listed (subject to official notice of issuance) on all securities exchanges on which the Common Stock issued to the public in connection herewith may then be listed and/or quoted on The Nasdaq Stock Market, Inc. 12.
