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 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. 2.1 Net Exercise. Notwithstanding any provisions herein to the contrary, in lieu of exercising this Warrant by payment of cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being exercised) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Notice of Exercise in which event the Company shall issue to the Holder a number of shares of Series D Preferred computed using the following formula: X = Y - B ---- ---- A Where X = the number of shares of Series D Preferred to be issued to the Holder Y = the number of shares of Series D Preferred purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being exercised (at the date of such calculation) A = the fair market value of one share of the Series D Preferred (at the date of such calculation) B = Exercise Price (as adjusted to the date of such calculation) For purposes of the above calculation, the fair market value of one share of Series D Preferred shall be determined by the Company's Board of Directors in good faith. 2.2 Vesting Schedule. Until (i) the expiration of the Exercise Period or (ii) all of the Exercise Shares have fully vested in accordance with this Section 2.2, the Holder's right to acquire the Exercise Shares shall be subject to a vesting schedule such that, as of any given date, the Holder shall be entitled to exercise its right to purchase that number of Exercise Shares equal to (i) one-half of the Drawn-Down Amount under the Loan Amendment, (ii) divided by 150. 2.3 Automatic Exercise Upon Redemption.

COVENANTS OF THE COMPANY. 3.1 Covenants as to Exercise Shares. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant (and all shares of Common Stock issuable upon the conversion of the Exercise Shares in accordance with the Series D Certificate of Determination) will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares of its Series D Preferred (and Common Stock issuable upon the conversion of the Series D Preferred in accordance with the Series D Certificate of Determination) to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of Series D Preferred (or Common Stock issuable upon the conversion of the Series D Preferred in accordance with the Series D Certificate of Determination) shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Series D Preferred and/or Common Stock to such number of shares as shall be sufficient for such purposes. 3.2 No Impairment.

The Holder has no such present intention. (b) The Holder recognizes that the Warrant and the Exercise Shares must be held indefinitely unless they are subsequently registered under the Act or an exemption from such registration is available.

Holder is aware that the conditions for resale set forth in Rule 144 have not been satisfied and that the Company presently has no plans to satisfy these conditions in the foreseeable future. 4.3 Disposition of Warrant and Exercise Shares. (a) The Holder further agrees not to make any disposition of all or any part of the Warrant or Exercise Shares in any event unless and until: (i) The Company shall have received a letter secured by the Holder from the Securities and Exchange Commission stating that no action will be recommended to the Commission with respect to the proposed disposition; (ii) There is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with said registration statement; or (iii) The Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, for the Holder to the effect that such disposition will not require registration of such Warrant or Exercise Shares under the Act or any applicable state securities laws.

THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED. 5. ADJUSTMENTS. 5.1 Reorganization, Reclassification, Consolidation, Merger or Sale. If any recapitalization, reclassification or reorganization of the capital stock of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its assets or other transaction shall be effected in such a way that holders of Series D Preferred shall be entitled to receive stock, securities, or other assets or property (an "Organic Change"), then, as a condition of such Organic Change, lawful and adequate provisions shall be made by the Company whereby the Holder shall thereafter have the right to purchase and receive (in lieu of the shares of the Series D Preferred immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such shares of stock, securities or other assets or property as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Series D Preferred equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby; provided, however, that in the event the value of the stock, securities or other assets or property (as determined in good faith by the Board of Directors of the Company) issuable or payable with respect to one share of the Series D Preferred of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby is in excess of the Stock Purchase Price hereof effective at the time of a merger and securities received in such reorganization, if any, are publicly traded, then this Warrant shall expire unless exercised prior to such Organic Change. In the event of any Organic Change, appropriate provision shall be made by the Company with respect to the rights and interests of the Holder of this Warrant to the end that the provisions hereof (including, without limitation, provisions for adjustments of the number of shares purchasable and receivable upon the exercise of this Warrant) shall thereafter be applicable, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company will not effect any such consolidation, merger or sale unless, prior to the consummation thereof, the successor corporation (if other than the Company) resulting from such consolidation or the corporation purchasing such assets shall assume the obligation to deliver to such Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holder may be entitled to purchase. 5.2 Certain Events. If any change in the outstanding Series D Preferred or any other event occurs as to which the other provisions of this Section 5 do not, in the reasonable opinion of the Board of Directors of the Company reached in good faith, fairly and equitably protect the purchase rights of the Holder of the Warrant in accordance with such provisions, then the Board of Directors of the Company shall make an adjustment in the number and class of shares available under the Warrant, or the application of such provisions, so as to protect such purchase rights as aforesaid. The adjustment shall be such as to give the Holder of the Warrant upon exercise for the same aggregate Exercise Price the total number, class and kind of shares as he would have owned had the Warrant been exercised prior to the event and had he continued to hold such shares until after the event requiring adjustment 5.3 Notices of Change. (a) Promptly following any adjustment in the number or class of shares subject to this Warrant, the Company shall give written notice thereof to the Holder, setting forth in reasonable detail and certifying the calculation of such adjustment. (b) The Company shall also give written notice to the Holder at least thirty (30) business days prior to the date on which an Organic Change shall take place. 6. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction. 7. AUTOMATIC EXERCISE UPON EXPIRATION. If this Warrant shall not have been exercised in full as to the shares that have vested pursuant to Sections 2.2 (the "Vested Shares") on or before the end of the Exercise Period (the "Termination Date"), then this Warrant shall be automatically exercised, without further action on the part of the Holder hereof, in full as to the Vested Shares (and the Holder hereof shall be deemed to be a Holder of the Exercise Shares issued upon such automatic exercise) on and as of the Termination Date, unless at any time on or before the Termination Date the Holder of this Warrant shall notify the Company in writing that no such automatic exercise is to occur. Payment of the Exercise Price due in connection with any such automatic exercise pursuant to this section shall be made by virtue of the net exercise provisions set forth in Section 2.1 of this Warrant, if applicable, unless at any time on or before the Termination Date the Holder of this Warrant shall notify the Company that such Holder elects one of the other payment options set forth herein or if the net exercise provisions set forth in Section 2.1 are for any reason inapplicable, the Holder shall be obligated to deliver the Exercise Price to the Company in cash. As promptly as practicable following any such automatic exercise, and in any event within thirty (30) days after the date that the Holder of this Warrant surrenders this Warrant to the Company for cancellation together with any required consideration therefor, the Company shall cause to be issued and delivered to the Holder hereof a certificate registered in the name of the Holder hereof (unless the Holder shall specifically instruct the Company otherwise) representing the Exercise Shares (or other security issuable upon the exercise hereof) issued in connection with such automatic exercise of this Warrant minus the number of Exercise Shares, if any, applied in payment of the Exercise Price as provided in Section 2.1. 8.
