The number of shares of Common Stock purchasable hereunder (the "Warrant Shares") is subject to adjustment as provided in Section 4 hereof.

This Warrant is subject to the following terms, provisions and conditions:

1. Manner of Exercise; Issuance of Certificates; Payment for Shares. Subject to the provisions hereof, including, without limitation, the limitations contained in Section 7 hereof, this Warrant may be exercised by the holder hereof, in whole or in part, by the surrender of this Warrant together with a completed exercise agreement in the form attached hereto (the "Exercise Agreement"), to the Company by 5:00 p.m. Boca Raton, Florida time on any business day at the Company's principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof) and upon payment to the Company in cash, by certified or official bank check or by wire transfer for the account of the Company, of the Exercise Price for the Warrant Shares. The Warrant Shares so purchased shall be deemed to be issued to the holder hereof or such holder's designee, as the record owner of such shares, as of the close of business on the date on which this Warrant shall have been surrendered and the completed Exercise Agreement shall have been delivered and payment shall have been made for such shares as set forth above or, if such day is not a business day, on the next succeeding business day. The Warrant Shares so purchased, representing the aggregate number of shares specified in the Exercise Agreement, shall be delivered to the holder hereof within a reasonable time, not exceeding two business days, after this Warrant shall have been so exercised (the "Delivery Period"). If the Company's transfer agent is participating in the Depository Trust Company ("DTC") Fast Automated Securities Transfer program, and so long as the certificates therefor do not bear a legend and the holder is not obligated to return such certificate for the placement of a legend thereon, the Company shall cause its transfer agent to electronically transmit the Warrant Shares so purchased to the holder by crediting the account of the holder or its nominee with DTC through its Deposit Withdrawal Agent Commission system ("DTC Transfer"). If the aforementioned conditions to a DTC Transfer are not satisfied, the Company shall deliver to the holder physical certificates representing, the Warrant Shares so purchased. Further, the holder may instruct the Company to deliver to the holder physical certificates representing the Warrant Shares so purchased in lieu of delivering such shares by way of DTC Transfer. Any certificates so delivered shall be in such denominations as may be requested by the holder hereof, shall be registered in the name of such holder or such other name as shall be designated by such holder and, following the date on which the Warrant Shares have been registered under the Securities Act, or otherwise may be sold by the holder pursuant to Rule 144 promulgated under the Securities Act (or a successor rule), shall not bear any restrictive legend. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of such certificates, deliver to the holder a new Warrant representing the number of shares with respect to which this Warrant shall not then have been exercised.

2. Period of Exercise. This Warrant is immediately exercisable, at any time or from time to time on or after the date of initial issuance of this Warrant (the "Issue Date") and before 5:00 p.m. Boca Raton, Florida time, on that date which is one (1) year after the effective date of the registration statement registering the Warrant Shares (the "Exercise Period").

3. Certain Agreements of the Company. The Company hereby covenants and agrees as follows:

(a) Shares to be Fully Paid. All Warrant Shares will, upon issuance in accordance with the terms of this Warrant, be validly issued, fully paid and nonassessable, and free from all taxes, liens, claims and encumbrances.

(b) Reservation of. Shares. During the Exercise Period, the Company shall at all times have authorized, and reserved for the purpose of issuance upon exercise of this Warrant, a sufficient number of shares of Common Stock to provide for the exercise in full of this Warrant.

(c) Listing. The Company shall promptly secure the listing of the shares of Common Stock issuable upon exercise of this Warrant upon each national securities exchange or automated quotation system, if any, upon which shares of Common Stock are then listed or become listed (subject to official notice of issuance upon exercise of this Warrant) and shall maintain, so long as any other shares of Common Stock shall be so listed, such listing of all shares if Common Stock from time to time issuable upon the exercise of this Warrant; and the Company shall so list on each national securities exchange or automated quotation system, as the case may be, and shall maintain such listing of, any other shares of capital stock of the Company issuable upon the exercise of this Warrant if and so long as any shares of the same class shall be listed on such national securities exchange or automated quotation system.

(d) Certain Actions Prohibited. The Company will not, by amendment of this charter or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant. Without limiting the generality of the foregoing, the Company will take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant.

(e) Successors and Assigns. This Warrant will be binding upon any entity succeeding to the Company by merger, consolidation, or acquisition of all or substantially all of the Company's assets.

(f) Blue Sky Laws. The Company shall, on or before the date of issuance of any Warrant Shares, take such actions as the Company shall reasonable determine are necessary to qualify the Warrant Shares for, or obtain exemption for the Warrant Shares for, sale to the holder of this Warrant upon the exercise hereof under applicable securities or "blue sky" laws of the states of the United States, and shall provide evidence of any such action so taken to the holder of this Warrant prior to such date; provided, however, that the Company shall not be required to qualify as a foreign corporation or file a general consent to service of process in any such jurisdiction.

4. Antidilution Provisions. During the Exercise Period, the Exercise Price and the number of Warrant Shares issuable hereunder shall be subject to adjustment from time to time as provided in this Section 4.

(a) Subdivision or Combination of Common Stock. If the Company, at any time during the Exercise Period, subdivides (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) its shares of Common Stock into a greater number of shares, then, after the date of record for effecting such subdivision, the Exercise Price(s) in effect immediately prior to such subdivision will be proportionately reduced. If the Company, at any time during the Exercise Period, combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) its shares of Common Stock into a smaller number of shares, then, after the date of record for effecting such combination, the Exercise Price(s) in effect immediately prior to such combination will be proportionately increased.

(b) Adjustment in Number of Shares. Upon each adjustment of the Exercise Price(s) pursuant to the provisions of this Section 4, the number of shares of Common Stock issuable upon exercise of this Warrant at each such Exercise Price shall be adjusted by multiplying a number equal to the Exercise Price in effect immediately prior to such adjustment by the number of shares of Common Stock issuable upon exercise of this Warrant at such Exercise Price immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price.

(c) Consolidation, Merger or Sale. In case of any consolidation of the Company with, or merger of the Company into, any other corporation, or in case of any sale or conveyance of all or substantially all of the assets of the Company other than in connection with a plan of complete liquidation of the Company at any time during the Exercise Period, then as a condition of such consolidation, merger or sale or conveyance, adequate provision will be made whereby the holder of this Warrant will have the right to acquire and receive upon exercise of this Warrant in lieu of the shares of Common Stock immediately theretofore acquirable upon the exercise of this Warrant, such shares of stock, securities, cash or assets as may be issued or payable with respect to or in exchange for the number of shares of Common Stock immediately therefore acquirable and receivable upon exercise of this Warrant had such consolidation, merger or conveyance not taken place. In any such case, the Company will make appropriate provision to insure that the provisions of this Section 4 hereof will thereafter be applicable as nearly as may be in relation to any shares of stock or securities thereafter deliverable upon the exercise of this Warrant. The Company will not effect any consolidation, merger or sale or conveyance unless prior to the consummation thereof, the successor corporation (if other than the Company) assumes by written instrument the obligations under this Warrant and the obligations to deliver to the holder of this Warrant such shares of stock as, in accordance with the foregoing provisions, the holder may be entitled to acquire.

(d) Distribution of Assets. In case the Company shall declare or make any distribution of its assets (or rights to acquire its assets) to holders of Common Stock as a partial liquidating dividend, stock repurchase, by way of return of capital or otherwise (including any dividend or distribution to the Company's shareholders of cash or shares (or rights to acquire shares) of capital stock of a subsidiary) (a "Distribution"), at any time during the Exercise Period, then the holder of this Warrant shall be entitled, upon a timely exercise of this Warrant for the purchase of any or all of the shares of Common Stock subject hereto, to receive the amount of such assets which would have been payable to the holder had such holder been the holder of such shares of Common Stock on the record date for the determination of shareholders entitled to such Distribution.

(e) Notice of Adjustment. Upon the occurrence of any event which requires any adjustment of the Exercise Price(s), then, and in each such case, the Company shall give notice thereof to the holder of this Warrant, which notice shall state the Exercise Price(s) resulting from such adjustment and the increase or decrease in the number of Warrant Shares purchasable at each such price upon exercise, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

(f) Certain Definitions. "Common Stock," for purposes of this Section 4, includes the Common Stock and any additional class of stock of the Company having no preference as to or distributions on liquidation, provided that the shares purchasable pursuant to this Warrant shall include only Common Stock in respect of which this Warrant is exercisable, or shares resulting from any subdivision or combination of such Common Stock, or in the case of any reorganization, reclassification, consolidation, merger, or sale of the character referred to in Section 4(c) hereof, the stock or other securities or property provided for in such Section.

5. Issue Tax. The issuance of certificates for Warrants upon the exercise of this Warrant shall be made without charge to the Holder of this Warrant or such shares for any issuance tax or other costs in respect thereof, provided that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than the holder of this Warrant.

6. No Rights or Liabilities as a Shareholder. This Warrant shall not entitle the holder hereof to any voting rights or other rights as a shareholder of the Company. No Provision of this Warrant, in the absence of affirmative action by the holder hereof to purchase Warrant Shares, and no mere enumeration herein of the rights or privileges of the holder hereof, shall give rise to any liability of such holder for the Exercise Price or as a shareholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

7. Transfer and Replacement of Warrant.

(a) Restriction on Transfer. This Warrant and the rights granted to the holder hereof are transferable, in whole or in part, upon written consent of the Company and surrender of this Warrant, together with a properly executed assignment, at the office or agency of the Company referred to in Section 7(c) below, provided, however, that any transfer or assignment shall be subject to the conditions set forth in Sections 7(d) and (e) hereof.

(b) Replacement of Warrant. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction, or mitigation of this Warrant and, in the case of any such loss, theft, or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Company, at its expense, will execute and deliver, in lieu thereof, a new Warrant of like tenor.

(c) Warrant Register. The Company shall maintain, at its principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof), a register for this Warrant, in which the Company shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee and each prior owner of this Warrant.

(d) Exercise or Transfer Without Registration. If, at the time of the surrender of this Warrant in connection with any exercise, transfer, or exchange of this Warrant, this Warrant (or, in the case of any exercise, the Warrant Shares issuable hereunder), shall not be registered under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such exercise, transfer, or exchange, (i) that the holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opnion shall be in form, substance and scope customary for opinionis of counsel in comparable transactions) to the effect that such exercise, transfer, or exchange may be made without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the holder or tranferee execute and deliver to the Company an investment letter in form and substance acceptable to the Company and (iii) that the transferee be an "accredited investor" as defined in Rule 501(a) promulgated under the Securities Act; provided that no such opinion, letter, or status as an "accredited investor" shall be required in connection with a transfer pursuant to Rule 144 under the Securities Act.

(e) Additional Restrictions on Exercise or Transfer. Notwithstanding anything contained herein to the contrary, this Warrant shall not be exercisable by a holder hereof to the extent (but only to the extent) that (i) the number of shares of Common Stock beneficially owned by such holder and its affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unexercised portion of the Warrants or the unexercised or unconverted portion of any other securities of the Company (including debentures) subject to a limitation on conversion or exercise analogous to the limitation contained herein) and (ii) the number of shares of Common Stock issuable upon exercise of the Warrants (or portion thereof) with respect to which the determination described herein is being made, would result in beneficial ownership by such holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock. To the extent the above limitation applies, the determination of whether and to what extent this Warrant shall be exercisable with respect to other securities owned by such holder shall be in the sole discretion of the holder and submission of this Warrant for full or partial exercise shall be deemed to be the holder's determination of whether and the extend to which this Warrant is exercisable, in each case subject to such aggregate percentage limitation. No prior inability to exercise the Warrants pursuant to this Section shall have any effect on the applicability of the provisions of this Section with respect to any subsequent determination of exercisability. For purposes of the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934.
