(b) The Holder shall pay the Exercise Price for all Warrant Shares purchased hereunder in full in cash or by certified check or wire transfer of immediately available funds.

2.2 Warrant Shares . The maximum number of Common Shares that Holder is entitled to purchase hereunder shall be _________ shares, as may be adjusted, on the terms and conditions set forth herein.

2.3 Expenses and Taxes . The Company shall pay all expenses and taxes (including all documentary, stamp, transfer or other transactional taxes) attributable to the preparation, issuance or delivery of this Warrant and of the Common Shares issuable upon exercise of this Warrant, other than income taxes.

2.4 Reservation of Common Shares . So long as this Warrant remains outstanding, the Company shall reserve, free from preemptive or similar rights, out of its authorized but unissued Common Shares, and solely for the purpose of effecting the exercise of this Warrant, a sufficient number of Common Shares to provide for the exercise of this Warrant.

2.5 Valid Issuance . All Common Shares issued upon exercise of this Warrant will, upon payment of the Exercise Price and issuance by the Company, be duly authorized, validly and legally issued, fully paid and nonassessable and free and clear of all taxes, liens, security interests, charges and other encumbrances or restrictions with respect to the issuance thereof and, without limiting the generality of the foregoing, the Company shall take all actions necessary to ensure such result and shall not take any action which will cause a contrary result.

2.6 Acknowledgment of Rights . At the time of the exercise of this Warrant in accordance with the terms hereof and upon the written request of the Holder hereof, the Company will acknowledge in writing its continuing obligation to afford to such Holder any rights to which such Holder shall continue to be entitled after such exercise in accordance with the provisions of this Warrant; provided, however, that if the Holder hereof shall fail to make any such request, such failure shall not affect the continuing obligation of the Company to afford to such Holder any such rights.

2.7 Adjustment of Number of Shares . To prevent dilution of the rights granted under this Warrant, the Exercise Price and the number of Common Shares purchasable hereunder are subject to adjustment from time to time as follows:

(a) Conversion or Redemption of Common Shares . Should all of the Common Shares be at any time prior to the Expiration Date redeemed, exchanged, substituted or converted into shares or any other security of the Company, then this Warrant shall become immediately exercisable prior to such event for that number of Common Shares equal to the number of Common Shares that would have been received if this Warrant had been exercised in full and the Common Shares received thereupon had been simultaneously converted immediately prior to such event, and the Exercise Price shall immediately be adjusted to equal the quotient obtained by dividing (i) the aggregate Exercise Price of the maximum number of shares of Common Shares for which this Warrant was exercisable immediately prior to such conversion, exchange, substitution or redemption, by (ii) the number of shares of Common Shares for which this Warrant is exercisable immediately after such conversion, exchange, substitution or redemption.

(b) Offer . If at any time while this Warrant, or any portion hereof, is outstanding and unexpired there shall be an offer for all of the Common Shares whether in the form of cash, securities or otherwise, then, as a part of such offer, lawful provision shall be made so that the Holder of this Warrant shall thereafter be entitled to receive upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price then in effect, the number of shares or other securities of the offeror that a holder of the Common Shares issuable upon exercise of this Warrant would have been entitled to receive in such offer if this Warrant had been exercised immediately before such offer, all subject to further adjustment as provided in this Section 2.7 . The foregoing provisions of this Section 2.7(b) shall similarly apply to successive offers and to the shares that are at the time receivable upon the exercise of this Warrant. If the per-share consideration payable to the Holder hereof for shares in connection with any such offer is in a form other than cash or marketable securities, then the value of such consideration shall be determined in good faith by the Company’s Board of Directors. In all events, appropriate adjustment (as determined in good faith by the Company’s Board of Directors) shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as reasonably may be, in relation to any shares or other property deliverable after that event upon exercise of this Warrant.

(c) Reclassification . If the Company, at any time while this Warrant, or any portion hereof, remains outstanding and unexpired by reclassification of securities or otherwise, shall change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities of any other class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights under this Warrant immediately prior to such reclassification or other change and the Exercise Price therefor shall be appropriately adjusted, all subject to further adjustment as provided in this Section 2.7 . No adjustment shall be made pursuant to this Section 2.7(c) , upon any conversion, exchange, substitution or redemption of the Common Shares that is the subject of Section 2.7(a) .

(d) Split, Subdivision or Combination of Shares . If the Company at any time while this Warrant, or any portion hereof, remains outstanding and unexpired shall split, subdivide or consolidate the securities as to which purchase rights under this Warrant exist, into a different number of securities of the same class, the Exercise Price for such securities shall be proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination and the number of Common Shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of all Common Shares issuable upon exercise of this Warrant shall remain unchanged.

(e) Adjustments for Dividends in Shares or Other Securities or Property . If while this Warrant remains outstanding and unexpired, the holders of the securities as to which purchase rights under this Warrant exist at the time shall have received, or, on or after the record date fixed for the determination of eligible shareholders, shall have become entitled to receive, without payment therefor, other or additional shares or other securities or property (other than cash) of the Company by way of dividend, then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of the security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of such other or additional shares or other securities or property (other than cash) of the Company that such holder would hold on the date of such exercise had it been the holder of record of the security receivable upon exercise of this Warrant on the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained such shares and/or all other additional shares available by it as aforesaid during such period, giving effect to all adjustments called for during such period by the provisions of this Section 2.7 .

(f) Other Dilutive Events . In case any event shall occur as to which the provisions of this Section 2.7 are not strictly applicable, but the failure to make any adjustment would not fairly protect the purchase rights presented by the Warrants in accordance with the essential intent and principles of this Section 2.7 , then, in each such case, the Company shall make a good faith adjustment to the Exercise Price and the number of Common Shares in accordance with the intent of this Section 2.7 and, upon the written request of the Holder, shall appoint an independent financial expert, which shall give their opinion upon the adjustment, if any, on a basis consistent with the essential intent and principles of this Section 2.7 .

(g) Certificate as to Adjustments . Upon the occurrence of each adjustment or readjustment pursuant to this Section 2.7 , the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Holder of this Warrant a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request, at any time, of any such Holder, furnish or cause to be furnished to such Holder a like certificate setting forth: (i) such adjustments and readjustments, (ii) the Exercise Price at the time in effect, and (iii) the number of shares and the amount, if any, of other property that at the time would be received upon the exercise of the Warrant.

(h) No Impairment . The Company will not, by any voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Section 2.7 and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder of this Warrant against impairment.

2.8 No Fractional Common Shares . The Company shall not be required to issue any fractional Common Share on the exercise of this Warrant.
