ARTICLE 1

EXERCISE OF WARRANT.

1.1             Mechanics of Exercise .  Subject to the terms and conditions hereof, this Warrant may be exercised by the Holder during the period set forth above, in whole or in part, by (i) delivery of a written notice to the Company, in the form attached hereto as Appendix 1 (the “ Exercise Notice ”), of the Holder’s election to exercise this Warrant and (ii) payment to the Company of an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is being exercised (the “ Aggregate Exercise Price ”) in cash or by wire transfer of immediately available funds, by the issuance and delivery of a recourse promissory note substantially in the form attached hereto as Appendix 2 (each, a “ Recourse Note ”), or, if applicable, by cashless exercise pursuant to Section 1.3 .  The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder.  Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares.  On the next business day after the date on which the Company has received each of the Exercise Notice and the Aggregate Exercise Price (the “ Exercise Delivery Documents ”) by 5:30 p.m. Eastern time on a business day (such next business day, the “ Share Delivery Date ”), the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Delivery Documents to the Holder and the Company’s transfer agent (the “ Transfer Agent ”) and credit such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with The Depository Trust Company (DTC) Fast Automated Securities Transfer (FAST) Program through its Deposit/Withdrawal Agent Commission (DWAC) system.  In the event the Company receives the Exercise Delivery Documents after 5:30 p.m. Eastern time, the Share Delivery Date will be computed from the next business day.  Upon delivery of the Exercise Delivery Documents, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account.  If this Warrant is submitted in connection with any exercise pursuant to this Section 1.1 and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than three Business days after any exercise and return of the previously issued Warrant and at its own expense, issue a new Warrant (in accordance with Section 6.4) representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised.  No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number.  The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant.  Any certificate representing Warrant Shares shall bear a restrictive legend until and unless a registration statement permitting the lawful resale of such Warrant Shares is effective.

1.2             Exercise Price .  For purposes of this Warrant, “ Exercise Price ” means an amount per Warrant Share equal to the Closing Sale Price of a Share of Common Stock on the Trading Day immediately preceding the Issuance Date, subject to adjustment as provided herein.

1.3             Cashless Exercise .  Notwithstanding anything contained herein to the contrary, if at any time there is not a current, valid and effective registration statement covering the Warrant Shares that are the subject of the Exercise Notice (the “ Unavailable Warrant Shares ”), the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “ Net Number ” of shares of Common Stock determined according to the following formula (a “ Cashless Exercise ”):

Net Number = (B-C) x A

For purposes of the foregoing formula:

A = the total number of shares with respect to which this Warrant is then being exercised.

B = the average of the Closing Sale Prices of the shares of Common Stock (as reported by Bloomberg) for the five (5) consecutive Trading Days ending on the date immediately preceding the date of the Exercise Notice.

C = the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

1.4             Company’s Failure to Timely Deliver Securities .   If the Company shall fail for any reason or for no reason to timely credit the Holder’s balance account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant, then, in addition to all other remedies available to the Holder, the Company shall pay in cash to the Holder on each day that the issuance of such shares of Common Stock is not timely effected an amount equal to 1.5% of the product of (A) the sum of the number of shares of Common Stock not issued to the Holder on a timely basis and to which the Holder is entitled and (B) the Closing Sale Price of the shares of Common Stock on the Trading Day immediately preceding the last possible date which the Company could have issued such shares of Common Stock to the Holder without violating Section 1.1 .  In addition to the foregoing, if after the Company’s receipt of the facsimile copy of a Exercise Notice the Company shall fail to timely credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise hereunder, and the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a “ Buy-In ”), then the Company shall, within one Trading Day after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “ Buy-In Price ”), at which point the Company’s obligation to credit such Holder’s balance account with DTC shall terminate, or (ii) promptly honor its obligation to credit such Holder’s balance account with DTC and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock sold by Holder in satisfaction of its obligations, times (B) the Closing Bid Price on the date of exercise.

1.5             Exercise Limitation .   Notwithstanding any other provision, at no time may the Holder exercise this Warrant such that the number of Warrant Shares to be received pursuant to such exercise aggregated with all other shares of Common Stock then owned by the Holder beneficially or deemed beneficially owned by the Holder would result in the Holder owning more than 4.99% of all of such Common Stock as would be outstanding on such Exercise Date, as determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.  In addition, as of any date, the aggregate number of shares of Common Stock into which this Warrant is exercisable within 61 days, together with all other shares of Common Stock then beneficially owned (as such term is defined in Rule 13(d) under the Exchange Act) by Holder and its affiliates, shall not exceed 9.99% of the total outstanding shares of Common Stock as of such date.

1.6             Restrictions .   For so long as Holder holds any Warrant Shares, Holder will not:  (i) vote any shares of Common Stock owned or controlled by it, solicit any proxies, or seek to advise or influence any Person with respect to any voting securities of the Company; (ii) engage or participate in any actions, plans or proposals which relate to or would result in (a) acquiring additional securities of the Company, alone or together with any other Person, which would result in beneficially owning or controlling more than 9.99% of the total outstanding Common Stock or other voting securities of the Company, (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving Company or any of its subsidiaries, (c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries, (d) any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board, (e) any material change in the present capitalization or dividend policy of the Company, (f) any other material change in the Company’s business or corporate structure, including but not limited to, if the Company is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by Section 13 of the Investment Company Act of 1940, (g) changes in the Company’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any Person, (h) causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, (i) a class of equity securities of the Company becoming eligible for termination of registration pursuant  to Section 12(g)(4) of the Act, or (j) any action, intention, plan or arrangement similar to any of those enumerated above; or (iii) request the Company or its directors, officers, employees, agents or representatives to amend or waive any provision of this Section 1.6 .

1.7             Disputes .   In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 12 .

1.8             Insufficient Authorized Shares .   If at any time while any of the Warrants remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of the Warrants at least a number of shares of Common Stock equal to 110% of the number of shares of Common Stock as shall from time to time be necessary to effect the exercise of all of the Warrants then outstanding (the “ Required Reserve Amount ”) (an “ Authorized Share Failure ”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Warrants then outstanding.  Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than 90 days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock.  In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal.

ARTICLE 2

ADJUSTMENT UPON SUBDIVISION OR COMBINATION OF COMMON STOCK.

If the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased.  If the Company at any time on or after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased.  Any adjustment under this ARTICLE 2 shall become effective at the close of business on the date the subdivision or combination becomes effective.

ARTICLE 3

PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS

3.1             Purchase Rights .   In addition to any adjustments pursuant to ARTICLE 2  above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder co
