at any time shall be issuable in exchange for or in replacement of such common stock.  The term “Affiliate” shall mean any Person that, directly or indirectly through one or more intermediaries, controls or is controlled by or is under common control with a Person, as such terms are used in and construed under Rule 144 promulgated by the SEC pursuant to the Securities Act of 1933, as amended.

2.              Holder of Warrant .  The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register” ), in the name of the record Holder hereof from time to time.  The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary from the transferee and transferor.

3.              Recording of Transfers .  Subject to Section 6, the Company shall register the transfer of any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached hereto duly completed and signed, to the Company at its address specified herein.  As a condition to the transfer, the Company may request a legal opinion as contemplated by the legend above and related terms of the Purchase Agreement.  Upon any such registration or transfer, a new Warrant to purchase Common Stock, in substantially the form of this Warrant (any such new Warrant, a “New Warrant” ), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a holder of a Warrant.

4.              Exercise and Duration of Warrants .

(a)           This Warrant shall be exercisable by the registered Holder in whole or in part at any time and from time to time on or after the date hereof to and including the Expiration Date by delivery to the Company of a duly executed facsimile copy of the Exercise Notice form annexed  hereto (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of such Holder appearing on the books of the Company).  At 6:30 p.m., New York City time on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value.  The Company may not call or redeem all or any portion of this Warrant without the prior written consent of the Holder.  If at any time (i) this Warrant is exercised after one year from the date of issuance of this Warrant but before the Expiration Date and (ii) during the Trading Day period immediately preceding the Holder’s delivery of an Exercise Notice in respect of such exercise, a Registration Statement (as defined in the Registration Rights Agreement) covering the Warrant Shares that are the subject of the Exercise Notice (the “ Unavailable Warrant Shares ”) is not available for the resale of such Unavailable Warrant Shares, the Holder of this Warrant also may exercise this Warrant as to any or all of such Unavailable Warrant Shares 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 a reduced number of shares of Common Stock (the “ Net Number ”) determined according to the following formula (a “ Cashless Exercise ”):

Net Number = (A x B) - (A x C)

--------------------

B

2

For purposes of the foregoing formula:

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

B= the VWAP on the Trading Day 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.

VWAP = For any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price per share of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg Financial L.P. (based on a Trading Day from 9:30 a.m. Eastern Time to 4:02 p.m. Eastern Time); (b) if the Common Stock is not then listed or quoted on a Trading Market and if prices for the Common Stock are then quoted on the OTC Bulletin Board, the volume weighted average price per share of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board; (c) if the Common Stock is not then listed or quoted on the OTC Bulletin Board and if prices for the Common Stock are then reported in the “Pink Sheets” published by the Pink Sheets, LLC (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported; or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Holder and reasonably acceptable to the Company.

There cannot be a Cashless Exercise unless “B” exceeds “C”.

(b)           The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 4(a) or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, such Holder (together with such Holder’s Affiliates, and any other person or entity acting as a group together with such Holder or any of such Holder’s Affiliates), as set forth on the applicable Notice of Exercise, would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by such Holder or any of its Affiliates and (B) 

3

exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 4(b), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act” ) and the rules and regulations promulgated thereunder, it being acknowledged by a Holder that the Company is not representing to such Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and such Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 4(b) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by such Holder together with any Affiliates) and of which a portion of this Warrant is exercisable shall be in the sole discretion of a Holder, and the submission of a Notice of Exercise shall be deemed to be each Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by such Holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4(b), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Form 10-Q or Form 10-K, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Company’s transfer agent setting forth the number of shares of Common Stock outstanding.  For any reason and at any time, upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by such Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Beneficial Ownership Limitation provisions of this Section 4(b) may be waived by such Holder, at the election of such Holder, upon not less than 61 days’ prior notice to the Company to change the Beneficial Ownership Limitation to 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant, and the provisions of this Section 4(b) shall continue to apply. Upon such a change by a Holder of the Beneficial Ownership Limitation from such 4.99% limitation to such 9.99% limitation, the Beneficial Ownership Limitation may not be further waived by such Holder. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 4(b)) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.  Notwithstanding anything contained

4

in this Warrant to the contrary, the limitations of this paragraph shall not apply to any Affiliated Investor, as that term is defined in the Purchase Agreement.

(c)           Additional Conversion Limitation .  Until the Charter Amendment (as defined in the Purchase Agreement) has been filed with, and accepted by, the Delaware Secretary of State, no Buyer (as defined in the Purchase Agreement) shall be issued, upon conversion or exercise of such Buyer’s Exchange Notes (as defined in the Purchase Agreement), Preferred Shares (as defined in the Purchase Agreement), or Warrants, a number of shares of Common Stock in the aggregate for all such conversions or exercises greater than the product of the Conversion Cap (as defined below) multiplied by a fraction, the numerator of which is the aggregate purchase price paid by the Buyer for all of the Exchange Notes, Preferred Shares, and Warrants purchased by the Buyer pursuant to the Purchase Agreement and the denominator of which is $23,124,933.33, which is the aggregate purchase price paid by all of the Buyers for all of the Exchange Notes, Preferred Shares, and Warrants purchased pursuant to the Purchase Agreement (with respect to each Buyer, the “Conversion Cap Allocation” ).  In the event that any Buyer shall sell or otherwise transfer any of such Buyer’s Warrants, the transferee shall be allocated a pro rata portion of such Buyer’s Conversion Cap Allocation based on the exercise price of the Warrants purchased by the Buyer, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Conversion Cap Allocation allocated to such transferee. The term “Conversion Cap” shall mean 32,985,406 shares of Common Stock, which represents all shares of authorized but unissued Common Stock as of the date of the Purchase Agreement to the extent not previously reserved for issuance pursuant to Convertible Securities and Options existing prior to such date. The term “ Convertible Securities ” means any stock or securities (other than Options) directly or indirectly convertible into or exercisable or exchangeable for Common Stock.  The term “ Options ” means any rights, warrants or options to subscribe for or purchase Common Stock or Convertible Securities.

5.              Delivery of Warrant Shares .

(a)           To effect exercises hereunder, the Holder shall not be required to physically surrender this Warrant upon exercise unless this Warrant ceases to be further exercisable for additional Warrant Shares.  Upon delivery of the Exercise Notice to the Company (with the attached Warrant Shares Exercise Log) at its address for notice set forth herein and upon payment of the Exercise Price multiplied by the number of Warrant Shares that the Holder intends to purchase hereunder, the Company shall promptly (but in no event later than three Trading Days after the Date of Exercise (as defined herein)) issue and deliver to the Holder, a certificate for the Warrant Shares issuable upon such exercise, which, unless otherwise required by the Purchase Agreement, shall be free of restrictive legends.  A “ Date of Exercise ” means the date on which the Holder shall have delivered to Company: (i) the Exercise Notice (with the Warrant Shares Exercise Log attached to it), appropriately completed and duly signed and (ii) except in the case of a Cashless Exercise, payment in full of the Exercise Price in immediately available funds or federal funds for the number of Warrant Shares so indicated by the Holder to be purchased.

(b)           If by the third Trading Day after a Date of Exercise the Company fails to deliver the required number of Warrant Shares in the manner required pursuant to Section 5(a), then the Holder will have the right to rescind such exercise.

5

(c)           If by the third Trading Day after a Date of Exercise the Company fails to deliver the required number of Warrant Shares in the manner required pursuant to Section 5(a), and if after such third Trading Day and prior to the receipt of such Warrant Shares, the Holder purchases in a bona fide arm’s length transaction for fair market value (in an open market transaction or otherwise) the number of shares of Common Stock necessary to deliver in satisfaction of a bona fide arm’s length sale for fair market value by the Holder of the Warrant Shares which the Holder was entitled to receive upon such exercise (a “ Buy-In ”), then the Company shall (1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the Holder’s total sales price (including brokerage commissions, if any) for the shares of Common Stock so sold 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 shares of Common Stock 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 and reasonably detailed documentation indicating the amounts requested by the Holder in respect of the Buy-In.

(d)           The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares.  Nothing herein shall limit a 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 shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

6.             Charges, Taxes and Expenses .  Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder.  The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

7.              Replacement of Warrant .  If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and ownership thereof and customa
