(i) Manner of Exercise.  This Warrant may be exercised, in whole or in part, at any time or from time to time, during the period commencing as of 9:30:01 a.m., New York time, on the day immediately following the Initial Exercise Date and ending as of 5:30 p.m., New York time, on the Expiration Date (the “Exercise Period”), for _________________ fully paid and non-assessable shares of Common Stock (the “Warrant Shares”), for an exercise price per share equal to the Exercise Price, in accordance with this Section 2(a).  Subject to the terms and conditions hereof, this Warrant may be exercised by the Holder on any day on or after the Exercisability Date, in whole or in part, by delivery of a written notice, in the form attached hereto as Attachment I (the "Exercise Notice"), of the Holder's election to exercise this Warrant.  Within two (2) days following the Exercise Notice, the Holder shall make 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, or provided the conditions for cashless exercise set forth in Section 2(b) are satisfied, by notifying the Company that this Warrant is being exercised pursuant to Section 2(b).  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 or before the first (1st) Business Day following the date on which the Company has received the Exercise Notice, the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Notice to the Holder and the Company's transfer agent (the "Transfer Agent").  Upon delivery of the Exercise Notice, 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 or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be.  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  The date on which the Company receives the Notice of Exercise shall be deemed to be the date of exercise (the “Date of Exercise”).

3

(b) Cashless Exercise. Notwithstanding the provisions of Section 2(a) above (requiring payment by wire transfer), the Company agrees that, if at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Warrant Shares to the Holder, then Holder shall have the right at such time to exercise this Warrant in full or in part on a cashless basis, computed using the following formula:

X = Y (A - B)

     A

Where:

X = The number of Warrant Shares to be issued to the Holder pursuant to this cashless exercise;

Y = The number of Warrant Shares in respect of which the net issue election is made;

A = The Fair Market Value  (as defined below) of one Warrant Share at the time the cashless exercise election is made; and

B = The Exercise Price then in effect at the time of such exercise.

The term “Fair Market Value” shall mean, on any given day: (A) if the class of Warrant Shares is exchange-traded, the average of the closing sales prices per share of the class of Warrant Shares for the trading day prior to the applicable date of determination of Fair Market Value; or (B) if the class of Warrant Shares is not listed or admitted to trading on any securities exchange but is regularly traded in any over-the-counter market, then the average of the bid and ask prices per share of the class of Warrant Shares for trading day prior to the applicable date of determination of Fair Market Value; or (C) if the class of Warrant Shares is not traded as described in clauses (A) or (B), then the per share fair market value of the class of Warrant Shares as determined in good faith by the Company’s Board of Directors.

4

(c) Delivery of Certificates.  Subject to the provisions below, upon receipt of the Notice of Exercise, the Company shall as soon as reasonably practicable instruct its transfer agent to prepare certificates for the Warrant Shares to be received by the Holder upon such exercise.  The Company shall, at its own cost and expense, cause the transfer agent to deliver such certificates to the Holder (or to such other nominee as may be designated by the Holder) within three Business Days following the Date of Exercise (the “Delivery Period”).  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 as of the Date of Exercise, irrespective of the date such certificates are actually delivered by the transfer agent to the Holder or are credited to the Holder’s DTC account, as the case may be.  If fewer than all of the Warrant Shares purchasable under the Warrant are purchased, the Company will, upon such partial exercise, execute and deliver to the Holder a new Warrant (dated as of the Issue Date), in the same form and tenor as this Warrant, evidencing that portion of the Warrant not exercised.

(d) Delivery of Electronic Shares. In lieu of delivering physical certificates representing the Warrant Shares issuable upon exercise (provided that the transfer agent is participating in the DTC Fast Automated Securities Transfer program and provided further that the Holder provides the transfer agent with information required in order to issue such Warrant Shares to the Holder electronically), upon the request of the Holder as set forth in the Notice of Exercise, the Company shall cause its transfer agent to electronically transmit, within the Delivery Period, the Warrant Shares issuable upon exercise to the Holder by crediting Holder’s account with DTC through its Deposit Withdrawal Agent Commission system.  Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates.

(e) No Fractional Shares.  If a fractional share of Warrant Shares would, but for the provisions of this Section 2(d), be issuable upon exercise of the rights represented by this Warrant, the Company shall (i) round a half share or greater to be delivered to Holder up to the next whole share and (ii) round a less-than-half share to be delivered to Holder down to the nearest whole share.

(f) Buy-In.  Notwithstanding anything else to the contrary contained herein, in addition to any other rights available to the Holder, if the Company fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the applicable Warrant Shares purchased upon exercise hereof or credit the Holder’s balance account with DTC, as applicable, on or before the end of the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company hereunder), and if after such date the Holder purchases shares of Common Stock to deliver in satisfaction of a sale by the Holder of Warrant Shares that the Holder anticipated receiving from the Company upon exercise of this Warrant (a “Buy-In”), then the Company shall, within three Business Days after the Holder’s request, (1) pay cash to the Holder the amount by which (x) the Holder’s total purchase price (including commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue, by (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored, or deliver to the Holder the number of Warrant Shares that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder.  The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company.  Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing the Warrant Shares as required pursuant to the terms hereof.

5

(g) No Charge to Holder Upon Issuance.  The issuance of Warrant Shares upon exercise of this Warrant shall be made without charge to Holder for any issuance tax in respect thereof or other cost incurred by the Company in connection with such exercise and the related issuance of Warrant Shares (other than any transfer taxes resulting from the issuance of Warrant Shares to any person other than Holder).

(h) Reservation of Shares.  During the Exercise Period, the Company shall reserve and keep available out of its authorized but unissued Common Stock such number of Warrant Shares issuable upon the full exercise of this Warrant.  All Warrant Shares which are so issuable shall, when issued and upon the payment of the applicable Exercise Price, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges and not subject to the pre-emptive rights of any holder of Common Stock or any other class or series of stock of the Company.  During the Exercise Period, the Company shall not take any action which would cause the number of authorized but unissued Common Stock to be less than the number of such shares required to be reserved hereunder for issuance upon exercise of this Warrant.

(i) Limitations on Exercises.  Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable by the Holder hereof to the extent (but only to the extent) that the Holder or any of its affiliates would beneficially own in excess of [9.98/4.9]% (the “Maximum Percentage”) of the Common Stock.  To the extent the above limitation applies, the determination of whether this Warrant shall be exercisable (vis-à-vis other convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of which such securities shall be exercisable (as among all such securities owned by the Holder) shall, subject to such Maximum Percentage limitation, be determined on the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be).  No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability.  For the purposes of this paragraph, beneficial ownership and all determinations and calculations (including, without limitation, with respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the Exchange Act.  The limitations contained in this paragraph shall apply to a successor Holder of this Warrant.  For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding, including by virtue of any prior conversion or exercise of convertible or exercisable securities into Common Stock.

6

3. Adjustments in Certain Events.  The number, class, and price of Warrant Shares for which this Warrant may be exercised are subject to adjustment from time to time upon the happening of certain events as follows:

(a) Subdivisions, Combinations and Other Issuances.  If the outstanding shares of the Company’s Common Stock are divided into a greater number of shares, by forward stock split or otherwise, or a dividend in stock is paid on the Common Stock, then the number of shares of Warrant Shares for which the Warrant is then exercisable will be proportionately increased and the Exercise Price will be proportionately reduced.  Conversely, if the outstanding shares of Common Stock are combined into a smaller number of shares of Common Stock, by reverse stock split or otherwise, then the number of Warrant Shares for which the Warrant is then exercisable will be proportionately reduced and the Exercise Price will be proportionately increased.  The increases and reductions provided for in this Section 3(a) will be made with the intent and, as nearly as practicable, the effect that neither the percentage of the total equity of the Company obtainable on exercise of the Warrants nor the price payable for such percentage upon such exercise will be affected by any event described in this Section 3(a).

(b) Merger, Consolidation, Reclassification, Reorganization, Etc.  In case of any change in the Common Stock through merger, consolidation, reclassification, reorganization, partial or complete liquidation, purchase of all or substantially all the assets of the Company, or other change in the capital structure of the Company, then, as a condition of such change, lawful and adequate provision will be made so that the Holder will have the right thereafter to receive upon the exercise of the Warrant the kind and amount of shares of stock or other securities or property to which the Holder would have been entitled if, immediately prior to such event, the Holder had held the number of Warrant Shares obtainable upon the exercise of the Warrant.  In any such case, appropriate adjustment will be made in the application of the provisions set forth herein with respect to the rights and interest thereafter of the Holder, to the end that the provisions set forth herein will thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the exercise of the Warrant.  The Company will not permit any change in its capital structure to occur unless the issuer of the shares of stock or other securities to be received by the Holder, if not the Company, agrees to be bound by and comply with the provisions of this Warrant.

(c) Notice of Record Date, Etc.  In the event the Company shall propose to take any action of the types requiring an adjustment pursuant to this Section 3 or a dissolution, liquidation or winding up of the Company shall be proposed, the Company shall give notice to Holder as provided in Section 6 below, which notice shall specify the record date, if any, with respect to any such action and the date on which such action is to take place.  Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon the occurrence of such action or deliverable upon the exercise of the Warrant.  In the case of any action which will require the fixing of a record date, unless otherwise provided in this Warrant, such notice shall be given at least twenty (20) days prior to the date so fixed, and in case of all other action, such notice shall be given at least thirty (30) days prior to the taking of such proposed action.

7

(d) Stock Dividends.  If securities of the Company or securities of any subsidiary of the Company are distributed pro rata to holders of Common Stock, such number of securities will be distributed to the Holder or its assignee upon exercise of its rights hereunder as such Holder or assignee would have been entitled to if this Warrant had been exercised prior to the record date for such distribution.  The provisions with respect to adjustment of the Common Stock provided in this Section 3 will also apply to the securities to which the Holder or its assignee is entitled under this Section 3(d).

(e) Fundamental Transactions.  The Company shall not enter into or be party to a Fundamental Transaction unless (i)  the Successor Entity assumes in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 3(e), including agreements to deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction) and (ii) the Successor Entity (or its Parent Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market. Upon the consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of the applicable Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such shares of publicly traded common stock (or its equivalent) of the Successor Entity (or its Parent Entity) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant. Notwithstanding the foregoing, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 3(e) to permit the Fundamental Transaction without the assumption of this Warrant.  In addition to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of the Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.

8

(f) Black-Sholes.  Notwithstanding the foregoing, in the event of a Fundamental Transaction, at the request of the Holder delivered before the 90th day after such Fundamental Transaction, the Company (or the Successor Entity) shall purchase this Warrant from the Holder by paying to the Holder, within five Business Days after such request (or, if later, on the effective date of the Fundamental Transaction), cash in an amount equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of such Fundamental Transaction.

4. No Rights as a Stockholder.  Except as otherwise provided herein, the Holder will not, by virtue of ownership of the Warrant, be entitled to any rights of a stockholder of the Company but will, upon written request to the Company, be entitled to receive such quarterly or annual reports as the Company distributes to its stockholders.

5. Restrictions on Transfer; Legends.

(a) Registration or Exemption Required. Assuming the accuracy of the representations and warranties of the Holder contained in the Purchase Agreement, this Warrant has been issued in a transaction exempt from the registration requirements of the Securities Act by virtue of Regulation D and exempt from state registration or qualification under applicable state laws. Neither this Warrant nor the Warrant Shares may be pledged, transferred, sold or assigned except pursuant to an effective registration statement or an exemption to the registration requirements of the Securities Act and applicable state laws.

(c) Removal of Restrictive Legends. This Warrant and the certificates evidencing the Warrant Shares, as applicable, shall not contain any legend restricting the transfer thereof: (A) following any sale of such Warrant and/or the Warrant Shares pursuant to Rule 144, or (B) if such Warrant and Warrant Shares are eligible for sale under Rule 144(b)(1), or (C) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) and the Company shall have received an opinion of counsel to the Holder in form reasonably acceptable to the Company to such effect (collectively, the “Unrestricted Conditions”).  The Company shall cause its counsel to issue a legal opinion to its transfer agent if required by the transfer agent to effect the issuance of this Warrant or the Warrant Shares, as applicable, without a restrictive legend or removal of the legend hereunder.  The Company agrees that at such time as the Unrestricted Conditions are met, it will, no later than three (3) Trading Days following the delivery by the Holder to the Company or the transfer agent of this Warrant and a certificate representing Warrant Shares, as applicable, issued with a restrictive legend, deliver or cause to be delivered to such Holder this Warrant and/or a certificate (or electronic transfer) representing such shares that is free from all restrictive and other legends.

7. Non-Circumvention.  The Company hereby covenants and agrees that the Company will not, by amendment of its certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be reasonably required to protect the rights of the Holder.
