  This Warrant is being issued to Holder in connection with the Amended Bridge Loan Agreement (the “ Agreement ”) entered into as of even date as this Warrant by and between the Company and Holder. Any capitalized but undefined terms used herein shall have the meaning set forth in the Agreement unless the context otherwise requires.

1.  Method of Exercise; Payment.

(a)  Exercise. The purchase rights represented by this Warrant may be exercised, either for cash or on a cashless basis, pursuant to Section 1(b) , by the Holder, in whole or in part, at any time, or from time to time, by the surrender of this Warrant (with the notice of exercise form (the “ Notice of Exercise ”) attached hereto as Exhibit A duly executed) at the principal office of the Company, and by payment to the Company of an amount equal to the Exercise Price multiplied by the number of the Shares being purchased, which amount may be paid, at the election of the Holder, by wire transfer or certified check payable to the order of the Company. The person or persons in whose name(s) any certificate(s) representing Shares shall be issuable upon exercise of this Warrant shall be deemed to have become the holder(s) of record of, and shall be treated for all purposes as the record holder(s) of, the Shares represented thereby (and such Shares shall be deemed to have been issued) immediately prior to the close of business on the date or dates upon which this Warrant is exercised.

(b)  Cashless Exercise. This Warrant shall also be exercisable by means of a “cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A) , where:

(A) = the average of the high and low trading prices per share of Common Stock on the Trading Day preceding the date of such election as quoted on the OTC Markets Group Inc. QB tier (the “ OTCQB ”), or if the Common Stock is not then quoted on the OTCQB, then on such market or interdealer quotation system the Common Stock is then traded or quoted on;

(B) = the Exercise Price of this Warrant; and

(X) = the number of Shares issuable upon exercise of this Warrant in accordance with the terms of this Warrant and the Notice of Exercise.

(c)  Stock Certificates. In the event of any exercise of the rights represented by this Warrant, as promptly as practicable after this Warrant is surrendered and delivered to the Company along with all other appropriate documentation on or after the date of exercise and in any event within ten (10) days thereafter, the Company at its expense shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for the number of Shares issuable upon such exercise. In the event this Warrant is exercised in part, the Company at its expense will execute and deliver a new Warrant of like tenor exercisable for the number of Shares for which this Warrant may then be exercised.

(d)  Taxes. The issuance of the Shares upon the exercise of this Warrant, and the delivery of certificates or other instruments representing such Shares, shall be made without charge to the Holder for any tax or other charge in respect of such issuance.

2.  Warrant.

(a)  Transfer and Replacement. Subject to compliance with applicable securities laws, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto as Exhibit B duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be exercised by a new holder for the purchase of Warrant without having a new Warrant issued. The Holder consents that the Company may, if it desires, permit the transfer of this Warrant out of the Holder’s name only when the Holder’s request for transfer is accompanied by an opinion of counsel reasonably satisfactory to the Company that neither the sale nor the proposed transfer results in a violation of the Securities Act of 1933, as amended (the “ Securities Act ”), or any applicable state “blue sky” laws. At any time prior to the exercise hereof, this Warrant may be exchanged upon presentation and surrender to the Company, alone or with other warrants of like tenor of different denominations registered in the name of the same Holder, for another warrant or warrants of like tenor in the name of such Holder exercisable for the aggregate number of Shares as the warrant or warrants surrendered.

(b)  Replacement of Warrant. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction, or mutilation 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)  Cancellation. Payment of Expenses. Upon the surrender of this Warrant in connection with any transfer, exchange or replacement as provided in this Section 2 , this Warrant shall be promptly canceled by the Company. The Holder shall pay all taxes and all other expenses (including legal expenses, if any, incurred by the Holder or transferees) and charges payable in connection with the preparation, execution and delivery of Warrants pursuant to this Section 2 .

(d)  Warrant Register. The Company shall maintain, at its principal executive offices (or at the offices of the transfer agent for the Warrant or such other office or agency of the Company as it may designate by notice to the holder hereof), a register for this Warrant (the “ Warrant Register ”), 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.

3.  Rights and Obligations of Holders of this Warrant.

The Holder of this Warrant shall not, by virtue hereof, be entitled to any rights of a shareholder in the Company, either at law or in equity; provided, however, that in the event any certificate representing shares of Common Stock or other securities is issued to the holder hereof upon exercise of this Warrant, such holder shall, for all purposes, be deemed to have become the holder of record of such Common Stock on the date on which this Warrant, together with a duly executed Notice of Exercise, was surrendered and payment of the aggregate Exercise Price was made, irrespective of the date of delivery of such Common Stock certificate.

4.  Adjustments.

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

(b)  Adjustment in Number of Shares. Upon each adjustment of the Exercise Price pursuant to the provisions of this Section 4 , the number of shares of Common Stock issuable upon exercise of this Warrant 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 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, 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 or assets as may be issued or payable with respect to or in exchange for the number of shares of Common Stock immediately theretofore acquirable and receivable upon exercise of this Warrant had such consolidation, merger or sale 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 Section 4 and the obligations to deliver to the holder of this Warrant such shares of stock, securities or assets 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 (including cash) to holders of Common Stock as a partial liquidating dividend, by way of return of capital or otherwise, then, after the date of record for determining shareholders entitled to such distribution, but prior to the date of distribution, the holder of this Warrant shall be entitled upon 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, 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 resulting from such adjustment and the increase or decrease in the number of Warrant purchasable at such price upon exercise, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Such calculation shall be certified by the Chief Financial Officer of the Company.

(f)  Minimum Adjustment of Exercise Price. No adjustment of the Exercise Price shall be made in an amount of less than 1% of the Exercise Price in effect at the time such adjustment is otherwise required to be made, but any such lesser adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which, together with any adjustments so carried forward, shall amount to not less than 1% of such Exercise Price.

(g)  No Fractional Shares. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but the Company shall round up the number of shares to the issued.

(h)  Other Notices. In case at any time:

then, in each such case, the Company shall give to the holder of this Warrant (a) notice of the date on which the books of the Company shall close or a record shall be taken for determining the holders of Common Stock entitled to receive any such dividend, distribution, or subscription rights or for determining the holders of Common Stock entitled to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, notice of the date (or, if not then known, a reasonable approximation thereof by the Company) when the same shall take place. Such notice shall also specify the date on which the holders of Common Stock shall be entitled to receive such dividend, distribution, or subscription rights or to exchange their Common Stock for stock or other securities or property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, or winding-up, as the case may be. Such notice shall be given at least 30 days prior to the record date or the date on which the Company’s books are closed in respect thereto. Failure to give any such notice or any defect therein shall not affect the validity of the proceedings referred to in clauses (i), (ii), (iii) and (iv) above.

(i)  Certain Events. If any event occurs of the type contemplated by the adjustment provisions of this Section 4 but not expressly provided for by such provisions, the Company will give notice of such event as provided in Section 8 hereof, and the Company’s Board of Directors will make an appropriate adjustment in the Exercise Price and the number of shares of Common Stock acquirable upon exercise of this Warrant so that the rights of the holder shall be neither enhanced nor diminished by such event.

5.  Legends.

Prior to issuance of the shares of Common Stock underlying this Warrant, all such certificates representing such shares shall bear a restrictive legend to the effect that the Shares represented by such certificate have not been registered under the Securities Act, and that the Shares may not be sold or transferred in the absence of such registration or an exemption therefrom, such legend to be substantially in the form of the bold-face language appearing at the top of Page 1 of this Warrant.

6.  Disposition of Warrants or Shares.

The Holder of this Warrant, each transferee hereof and any holder and transferee of any Shares, by his or its acceptance thereof, agrees that no public distribution of Warrants or Shares will be made in violation of the provisions of the Securities Act. Furthermore, it shall be a condition to the transfer of this Warrant that any transferee thereof deliver to the Company his or its written agreement to accept and be bound by all of the terms and conditions contained in this Warrant.

7.  Merger or Consolidation.

The Company will not merge or consolidate with or into any other corporation, or sell or otherwise transfer its property, assets and business substantially as an entirety to another corporation, unless the corporation resulting from such merger or consolidation (if not the Company), or such transferee corporation, as the case may be, shall expressly assume, by supplemental agreement reasonably satisfactory in form and substance to the Holder, the due and punctual performance and observance of each and every covenant and condition of this Warrant to be performed and observed by the Company.

8.  Notices.

Except as otherwise specified herein to the contrary, all notices, requests, demands and other communications required or desired to be given hereunder shall only be effective if given in writing by certified or registered U.S. mail with return receipt requested and postage prepaid; by private overnight delivery service (e.g. Federal Express); by facsimile transmission (if no original documents or instruments must accompany the notice); or by personal delivery.
