In order to exercise this warrant with respect to all or any part of the Warrant Shares for which this warrant is at the time exercisable, Holder (or in the case of exercise after Holders death, Holders executor, administrator, heir or legatee, as the case may be) must take the following actions:  (a) Deliver to the Corporate Secretary of the Corporation an executed notice of exercise in substantially the form of attached to this Agreement (the Exercise Notice) in which there is specified the number of Warrant Shares that are to be purchased under the exercised warrant.  (b) Pay the aggregate Warrant Price for the purchased shares through one or more of the following alternatives:  (i) full payment in cash or by check made payable to the Corporations order;  (ii) full payment in shares of Common Stock valued at Fair Market Value on the Exercise Date (as such term is defined below);  (iii) full payment through a combination of shares of Common Stock valued at Fair Market Value on the Exercise Date and cash or check payable to the Companys order;  (iv) full payment effected through a broker-dealer sale and remittance procedure pursuant to which Holder shall provide concurrent irrevocable written instructions (i) to a brokerage firm to effect the immediate sale of the purchased shares and remit to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Warrant Price payable for the purchased shares and (ii) to the Company to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale transaction; or  (v) full payment through conversion of this warrant to purchase Warrant Shares into the number of fully paid and nonassessable Warrant Shares calculated pursuant to the following formula:  X   =   Y (A-B) A  where:  X = the number of Warrant Shares to be issued to the Holder;  Y = the number of Warrant Shares for which the conversion right is being exercised;  A = the Fair Market Value per share as of the last business day immediately preceding the date of exercise of such conversion right; and  B = the Warrant Price with respect to such Warrant Shares.  For all valuation purposes under this Agreement, the Fair Market Value per share of Common Stock on any relevant date shall be determined in accordance with the following provisions:  2     (i) If the Common Stock is not at the time listed or admitted to trading on any national securities exchange but is traded on the Nasdaq National Market, the Fair Market Value shall be the mean between the highest bid and lowest offered quotations of a share of Common Stock on such date (or if none, on the most recent date on which there were bid and offered quotations of a share of Common Stock), as reported by the Nasdaq National Market or any successor system.  (ii) If the Common Stock is at the time listed or admitted to trading on any national securities exchange, then the Fair Market Value shall be the closing selling price per share on the date in question on the securities exchange, as such price is officially quoted in the composite tape of transactions on such exchange.  If there is no reported sale of Common Stock on such exchange on the date in question, then the Fair Market Value shall be the closing selling price on the exchange on the last preceding date for which such quotation exists.  (iii) If the Common Stock is not listed on such date on any national securities exchange nor included in the Nasdaq National Market, but is traded in the over-the-counter market, the highest "bid" quotation of a share of Common Stock on such date (or if none, on the most recent date on which there were bid quotations of a share of Common Stock), as reported on the Nasdaq Smallcap Market or the NASD OTC Bulletin Board, as applicable.

The Holder shall pay any and all documentary stamp or similar issue or transfer taxes payable in respect of the issue or delivery of shares of Common Stock on exercise of this Warrant.
