(c) This Warrant.

Upon the exercise of the rights represented by this Warrant, a certificate or certificates for the Exercise Shares so purchased, registered in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant shall have been so exercised; and, unless this Warrant has expired, a new Warrant representing the number of shares of Common Stock (except a remaining fractional share), if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder hereof within such time.

The person in whose name any certificate or certificates for Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such Exercise Shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

In the absence of such markets for the Common Stock, the fair market value shall be determined by the Board of Directors of the Company in good faith.

3.2 Cash Dividends and Pro Rata Distributions . In the event that at any time or from time to time the Company shall distribute to all holders of Common Stock (i) any dividend or other distribution of cash, evidences of its indebtedness, shares of its capital stock or any other properties or securities or (ii) any options, warrants or other rights to subscribe for or purchase any of the foregoing (other than in each case, (w) the issuance of any rights under a shareholder rights plan, (x) any dividend or distribution described in Section 3.1, (y) any rights, options, warrants or securities described in Section 3.3 and (z) any cash dividends or other cash distributions from current or retained earnings), then the number of shares of Common Stock issuable upon the exercise of this Warrant shall be adjusted to a number determined by multiplying the number of shares of Common Stock issuable upon the exercise of this Warrant immediately prior to the record date for any such dividend or distribution by a fraction, the numerator of which shall be such Current Market Value (as hereinafter defined) per share of Common Stock on the record date for such dividend or distribution, and the denominator of which shall be such Current Market Value per share of Common Stock on the record date for such dividend or distribution less the sum of (x) the amount of cash, if any, distributed per

Such adjustments shall be made whenever any distribution is made and shall become effective as of the date of distribution, retroactive to the record date for any such distribution. No adjustment shall be made pursuant to this Section 3.2 which shall have the effect of decreasing the number of shares of Common Stock issuable upon exercise of this Warrant or increasing the Exercise Price.

“ Current Market Value ” per share of Common Stock or any other security at any date means (i) if the security is not registered under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), and/or traded on a national securities exchange, quotation system or bulletin board, (a) the value of the security, determined in good faith by the Board of Directors of the Company and certified in a board resolution, based on the most recently completed arm’s-length transaction between the Company and a Person other than an affiliate of the Company or between any two such Persons and the closing of which occurs on such date or shall have occurred within the six-month period preceding such date, or (b) if no such transaction shall have occurred within the six-month period, the value of the security as determined by an independent financial expert or an agreed upon financial valuation model or (ii) if the security is registered under the Exchange Act and/or traded on a national securities exchange, quotation system or bulletin board, the average of the daily closing bid prices (or the equivalent in an over-the-counter market) for each day on which the Common Stock is traded for any period on the principal securities exchange or other securities market on which the common Stock is being traded (each, a “ Trading Day ”) during the period commencing thirty (30) days before such date and ending on the date one day prior to such date.

3.3 Reorganization, Reclassification, Consolidation, Merger or Sale . If any recapitalization, reclassification or reorganization of the share capital of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its shares and/or assets or other transaction (including, without limitation, a sale of substantially all of its assets followed by a liquidation) shall be effected in such a way that holders of Common Stock shall be entitled to receive shares, securities or other assets or property (a “ Change ”), then, as a condition of such Change, lawful and adequate provisions shall be made by the Company whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such shares, securities or other assets or property as may be issued or payable with respect to or in exchange for the number of outstanding shares of Common Stock which such Holder would have been entitled to receive had such Holder exercised this Warrant immediately prior to the consummation of such Change. The Company or its successor shall promptly issue to Holder a new Warrant for such new securities or other property. The new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to give effect to the adjustments provided for in this Section 3 including, without limitation, adjustments to the Exercise Price and to the number of securities or property issuable upon exercise of the new Warrant.
