Unless being exercised on a cashless basis in accordance with Section 2(c), within three Trading Days following the date of exercise as aforesaid, the Holder shall deliver the Aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank (such date of delivery of the Aggregate Exercise Price, the “Exercise Date”). Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and this Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall inform the Holder if a Notice of Exercise has not been duly completed within one Business Day of receipt of such notice, but shall not refuse or object to the issuance of the Warrant Shares upon receipt of, and pursuant to, a duly completed Notice of Exercise. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

4

b)       Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $3.94, subject to adjustment hereunder (the “Exercise Price”).

c)       Cashless Exercise. If at the time of exercise of this Warrant there is no effective registration statement registering the resale of the Warrant Shares by the Holder, the Holder, at its option, may exercise this Warrant, in whole or in part, by means of a “cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(Y)*(A-B)] by (A), where:

(A) =  the average of the Closing Bid Price of the shares of Common Stock for the five consecutive Trading Days ending on the last Trading Day immediately preceding the date on which the Holder elects to exercise this Warrant by means of a “cashless exercise,” as set forth in the applicable Notice of Exercise (such date, the “Cashless Exercise Date”);

(B) =   the Exercise Price of this Warrant, as adjusted hereunder; and

(Y) =  the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise pursuant to Section 2(a) rather than a cashless exercise.

d)       Mechanics of Exercise.

i.         Delivery of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the Company’s transfer agent (the “Transfer Agent”) to the Holder by, at the Holder’s option, (A) crediting the account of the Holder’s prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B)  physical delivery to the address specified by the Holder in the Notice of Exercise by the date that is three Trading Days after the latest of (1) the delivery to the Company of the Notice of Exercise, (2) surrender of this Warrant (if required), (3) payment of the Aggregate Exercise Price as set forth above and (4) three Trading Days following the Cashless Exercise Date, if applicable (such date in (1), (2), (3) or (4), the “Warrant Share Delivery Date”). The applicable Warrant Shares shall be deemed to have been issued, and the Holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the applicable Exercise Date or the date that is three Trading Days following the Cashless Exercise Date, as applicable.

5

ii.       Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of the Holder and upon surrender of this Warrant, at the time of delivery of the certificate or certificates representing the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iii.       Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise. Any rescission by the Holder pursuant to this Section 2(d)(iii) shall not affect any other remedies available to the Holder under applicable law or equity as a result of the Company’s failure to timely deliver the Warrant Shares.

iv.       No Fractional Shares. No fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a Warrant Share that the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at the Holder’s election, either (A) pay to such Holder an amount in cash (by delivery of a certified or official bank check or by wire transfer of immediately available funds) equal to the product of (1) such fraction multiplied by (2) the Closing Bid Price of one Warrant Share on the Exercise Date or the Cashless Exercise Date, as applicable, or (B) round up to the next whole share.

v.       Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant pursuant to the terms hereof.

e)       Conditional Exercise. Notwithstanding any other provision hereof, if an exercise of any portion of this Warrant is to be made in connection with a public offering or a sale of the Company (pursuant to a merger, sale of stock, or otherwise), such exercise may, at the election of the Holder (set forth in the applicable Notice of Exercise), be conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be effective until immediately prior to the consummation of such transaction.

6

f)       Representations, Warranties and Covenants of the Company. The Company hereby represents, covenants and agrees, as applicable:

i.       As of the Initial Issuance Date, the Company (A) is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware, (B) has all requisite power and authority to own and operate its properties, to carry on its business as now conducted and as currently proposed to be conducted, to issue and enter into this Warrant and to carry out the transactions contemplated thereby, and (C) except where the failure to do so, individually or in the aggregate, has not had, and could not be reasonably expected to have, a material adverse effect on the business, assets, financial condition or operations of the Company, is qualified to do business and, where applicable is in good standing, in every jurisdiction where such qualification is required.

ii.       This Warrant is, and any Warrant issued in substitution for or replacement of this Warrant (including pursuant to Section 2(d)(ii)) shall be, upon issuance, duly authorized and validly issued. This Warrant constitutes, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency or other similar laws affecting the enforcement of creditors’ rights generally and by general principles of equity.

iii.       As of the Initial Issuance Date, the execution, delivery and performance by the Company of this Warrant does not and will not (A) violate any material provision of applicable law or the organizational documents of the Company, (B) conflict with, result in a breach of, or constitute (with the giving of any notice, the passage of time, or both) a default under any material agreement of the Company or (C) result in or require the creation or imposition of any lien upon any assets of the Company.

iv.       The Company covenants that, during the period this Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights represented by this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such action as may be reasonably necessary or appropriate to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, of any requirements of the Trading Market upon which the Common Stock may be listed or any preemptive or similar rights of any equity holder of the Company. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges (other than taxes in respect of any transfer occurring contemporaneously with such issue).

7

v.       Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation 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 of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (A) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (B) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (C) use its best efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

vi.       Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

g)       Representations and Warranties of the Holder. The Holder, by the acceptance hereof, represents and warrants that it is an “accredited investor” under Rule 501 promulgated pursuant to the Securities Act and that it is acquiring this Warrant and, upon any exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.

8

Section 3.         Certain Adjustments.

a)       Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides (by any stock split, recapitalization or otherwise) outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues by reclassification of shares of Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to (x) the record date for the determination of stockholders entitled to receive such dividend or distribution or (y) the effective date in the case of a subdivision, combination or re-classification by a fraction, the numerator of which shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the Aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b)       Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security, then in each such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction, the numerator of which shall be such VWAP on such record date less the then fair market value (as determined by the Board of Directors of the Company in good faith) at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of Common Stock, and the denominator of which shall be the VWAP determined as of the record date mentioned above. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

c)       Certain Events. If any event of the type contemplated by the provisions of this Section 3 but not expressly provided for by such provisions occurs, then the Board of Directors of the Company shall make an appropriate adjustment in the Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant so as to protect the rights of the Holder in a manner consistent with the provisions of this Section 3; provided, that no such adjustment pursuant to this Section 3(c) shall increase the Exercise Price or decrease the number of Warrant Shares issuable as otherwise determined pursuant to this Section 3.

9

d)       Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

e)       Notice to the Holder.

i.       Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall, at the request of the Holder, promptly compute such adjustment, in good faith, in accordance with the terms of this Warrant, and prepare a certificate setting forth such adjustment, including (A) a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable) and (B) in the case of adjustment pursuant to Section 3(b), a statement of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock, and setting forth a brief statement of the facts requiring such adjustment and certifying the calculation thereof. The Company will deliver a copy of each such certificate to the Holder as promptly as reasonably practicable following any adjustment of the Exercise Price, but in any event not later than ten Business Days thereafter.

ii.       Notice to Allow Exercise by the Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock or rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights of the Company, (D) the Company enters into or becomes bound by an agreement in connection with a Change of Control or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register (as defined below) of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distribution, redemption, rights or warrants are to be determined or (y) the date on which such Change of Control is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such Change of Control; provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein. Except as otherwise prohibited by applicable laws, to the extent that any notice provided pursuant to this Section 3(e)(ii) contains material, non-public information regarding the Company, the Company shall disclose such information regarding the Company in a Current Report on Form 8-K and file such Current Report on Form 8-K with the SEC no later than the second Trading Day following the date such notice is delivered to the Holder.
