In the event the Person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such Person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

(b) Registration.

(i) Warrant Register. The Company shall maintain books (“Warrant Register”) for the registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants, the Company shall issue and register the Warrants in the names of the respective holders.

(ii) Registered Holder. The term “Holder” shall mean, on or after the Detachment Date (as defined below), any Person in whose name ownership in the Warrants shall be registered upon the Warrant Register, and prior to the Detachment Date, the Person in whose name the Unit of which such Warrant or part thereof was originally part of, as registered upon the register relating to such Units. Prior to due presentment for registration or transfer of any Warrant, the Company may deem and treat the Holder as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on the Warrant Certificate made by anyone other than the Company), for the purpose of any exercise thereof, and for all other purposes, and the Company shall not be affected by any notice to the contrary.

4

(iii) Detachability of Warrants. The Series E Preferred Shares and Warrants comprising the Units will be immediately separable after the Issuance Date (the “Detachment Date”), subject to the receipt by the Company of written notice from the registered holder of the Units of such holder’s intent to separate the Series E Preferred Shares and Warrants.

Section 4. Exercise of Warrant.

(a) Each Warrant, when signed by the Company, may be exercised by the Holder thereof, in whole or in part, on any Business Day and at any time prior to 5:00 p.m., Eastern Time, on the Expiration Date. Any exercise of a Warrant shall be effected by:

(i) delivery to the Company at the principal executive office of the Company of a written notice, in the form attached as Exhibit A hereto (the “Exercise Notice”), properly completed and executed, of Holder’s election to exercise the Warrant, specifying the number of shares of Common Stock to be purchased;

(ii) payment of an amount equal to the Exercise Price multiplied by the number of shares of Common Stock being purchased upon exercise (A) in cash or wire transfer of immediately available funds payable to the Company; (B) by means of a cashless exercise pursuant to Section 4(c); (C) by surrender of all or a portion (as appropriate) of such Holder’s Series E Preferred Shares pursuant to Section 4(d); or (D) following the redemption of the Holder’s Series E Preferred Shares, by applying the Exercise Price Accrual credited to the account of such Holder pursuant to Section 4(e) (the foregoing methods set forth in (A) through (D) of this Section 4(a)(ii) referred to herein as the “Payment,” and any Payment may include any combination of such methods); and

(iii) the surrender to the Company at the principal executive office of the Company of the definitive Warrant Certificate evidencing the Warrants to be exercised.

The Company shall, not later than the fifth Business Day (the “Delivery Date”) following receipt of an Exercise Notice, the Payment and the Warrant Certificate (collectively, the “Exercise Documents”), arrange for its transfer agent, on or before the Delivery Date, to issue and surrender to a nationally recognized courier for overnight delivery to the address specified in the Exercise Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled. Upon delivery of the Exercise Notice and the Payment (the “Exercise Date”), the Holder shall be deemed for all corporate purposes to have become the holder of record of the shares of Common Stock with respect to which a Warrant has been exercised on the Delivery Date, irrespective of the date of delivery of the certificates evidencing the shares of Common Stock. Notwithstanding the foregoing, the Company shall not be obligated to deliver any securities pursuant to the exercise of a Warrant if, in the opinion of counsel to the Company, the exercise of such Warrant is not exempt from the registration requirements of the Securities Act or the shares of Common Stock issuable upon exercise of such Warrant are not qualified for sale or exempt from qualification under applicable securities laws of the states or other jurisdictions in which the Holder(s) thereof reside unless a registration statement under the Securities Act with respect to the shares of Common Stock issuable upon the exercise of such Warrant is effective. Warrants may not be exercised by, or securities issued to, any Holder in any state in which such exercise or issuance would be unlawful.

5

(b) Unless the rights represented by a Warrant have expired or been fully exercised, the Company shall, as soon as practicable and in no event later than five Business Days after receipt of the Exercise Documents and at its own expense, issue a new Warrant Certificate representing the right to purchase the number of shares of Common Stock purchasable immediately prior to exercise of the Warrant, less the number of shares purchased upon exercise of the Warrant.

(c) In lieu of or in addition to exercising a Warrant by means of paying via cash or wire transfer or pursuant to Section 4(d) or Section 4(e), the Holder may elect to make the Payment by means of receiving shares equal to the value of the Warrant (or portion thereof being exercised) by delivery and surrender of the Warrant together with the Exercise Notice in accordance with the terms hereof, duly completed to indicate a net issuance exercise and executed by the Holder, in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

X = Y(A-B)/A

(d) In lieu of or in addition to exercising a Warrant by means of paying via cash or wire transfer or pursuant to Section 4(c), the Holder may elect to make the Payment by surrender of Series E Preferred Shares. In such case, the Holder shall surrender the number of whole Series E Preferred Shares, properly endorsed to the Company, having an aggregate Liquidation Value (as defined in the Series E Certificate) equal to the Payment as calculated pursuant to Section 4(a) (less any amounts paid via cash or wire transfer or pursuant to Section 4(c)). Unless all of the shares represented by the certificate for the Series E Shares have been surrendered, the Company shall, as soon as practicable and in no event later than five Business Days after receipt of the Exercise Documents and at its own expense, issue a new certificate representing the remaining Series E Shares owned by the Holder. Notwithstanding the foregoing, no Holder shall be entitled to receive cash or other consideration in satisfaction of the excess of the aggregate Liquidation Value of the Series E Preferred Shares surrendered pursuant to this Section 4(d) over the required Payment (the “Excess Amount”), it being understood and agreed that the Excess Amount shall never exceed the Exercise Price payable upon exercise of a Warrant to purchase one share of Common Stock. In the event that a Holder exercises a Warrant and elects to make the Payment pursuant to this Section 4(d) and such exercise results in an Excess Amount, then at the Holder’s option (as indicated on the Exercise Notice) the Excess Amount: (i) shall be forfeited to the Company or (ii) may be applied to exercise a Warrant to purchase one additional share of Common Stock; provided, that the Holder shall pay an amount in cash equal to the difference between the Excess Amount and the Exercise Price of the Warrant; provided further, that this option (ii) shall not be available if the Holder does not hold at least one Warrant immediately following the exercise resulting in the Excess Amount. If the Holder does not make an election with respect to the Excess Amount in the Exercise Notice, then the Excess Amount will be deemed to be forfeited to the Company.

6

(e) If a Warrant is exercised following the redemption of the Holder’s Series E Preferred Shares, then in lieu of or in addition to exercising a Warrant by means of paying via cash or wire transfer or pursuant to Section 4(c), the Holder may elect to make the Payment by applying that amount of the Exercise Price Accrual credited to the account of such Holder equal to the Payment as calculated pursuant to Section 4(a) (less any amounts paid via cash or wire transfer or pursuant to Section 4(c)). Any amount of the Exercise Price Accrual applied upon such exercise shall be deemed to have been surrendered by such Holder to the Company.

(f) No fractional shares of Common Stock are to be issued upon the exercise of a Warrant, but rather the number of shares of Common Stock issued shall be rounded up or down to the nearest whole number.

(g) Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at the close of business on the Expiration Date.

Section 5. Covenants as to Common Stock. The Company hereby covenants and agrees as follows:

(a) The Warrants will be, and any Warrants issued in substitution for or in replacement of the Warrants upon issuance will be, duly authorized, executed and delivered.

(b) All shares of Common Stock issuable upon exercise of the Warrants will be, upon issuance, validly issued, fully paid and nonassessable and free from all liens and charges with respect to the issue thereof.

(c) As long as the Warrants may be exercised, the Company will have authorized and reserved at least the number of shares of Common Stock needed to provide for the exercise of the rights then represented by each Warrant and any other Derivative Security then outstanding.

Section 6. Warrant Holder Not Deemed a Stockholder. Except as specifically provided in Section 4(a), nothing contained in this Agreement shall be construed to (a) grant the Holder any rights to vote or receive dividends or be deemed the holder of shares of the Company for any purpose, (b) confer upon the Holder any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, or (c) impose any liabilities on the Holder to purchase any securities or as a stockholder of the Company, whether asserted by the Company or creditors of the Company, prior to the issuance of the underlying shares of Common Stock.

7

Section 7. Ownership and Transfer.

(a) Prior to the Detachment Date, the Warrants may be transferred or exchanged only as part of the Unit in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such Unit. For the avoidance of doubt, each transfer of a Unit on the register relating to such Units shall operate also to transfer the Warrants included in such Unit. Following the Detachment Date and until the redemption of the Holder’s Series E Preferred Shares, the Warrants may only be offered, sold, transferred or assigned in conjunction with the sale, transfer or assignment of whole Units only. Any time after the redemption of the Holder’s Series E Preferred Shares, the Warrant related to such redeemed Series E Preferred Shares may only be offered, sold, transferred or assigned in conjunction with the sale, transfer or assignment of the Exercise Price Accrual associated therewith. Any attempted transfer of the Warrants in violation of this Section 7(a) shall be null and void ab initio.

(b) Warrants may be surrendered to the Company, together with a written request for exchange or transfer (which in the case of any transfer, shall be in the form attached to Exhibit A hereto), and thereupon the Company shall issue in exchange therefor one or more new Warrants as requested by the Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Company shall not cancel such Warrant and issue new Warrants in exchange therefor if the Company has received an opinion of counsel stating that such transfer may not be made or may not be made unless the new Warrants also bear a restrictive legend. Upon any such registration of transfer, the Company shall execute and deliver, in the name of the designated transferee, a new Warrant Certificate or Warrant Certificates of any authorized denomination evidencing in the aggregate a like number of unexercised Warrants.

(c) The delivery of the new Warrant Certificate by the Company to the transferee thereof shall be deemed to constitute acceptance by such transferee of all of the rights and obligations of a holder of a Warrant. Subject to the terms of this Section 7, a Warrant may be divided or combined with other warrants that carry the same rights upon presentation of the underlying Warrant Certificate at the principal executive office of the Company together with a written notice signed by the Holder specifying the names and denominations in which the new Warrant Certificates are to be issued.

(d) Upon the valid exchange or transfer of any Warrant in accordance with this Section 7, the Company shall register the transfer and the name of such transferee(s) upon the Warrant Register, and such transferee(s) shall become a Holder for all purposes thereafter.

Section 8. Adjustment of Exercise Price and Number of Shares. The Exercise Price and the number of shares of Common Stock issuable upon exercise of each Warrant shall be adjusted from time to time as follows:

(a) Stock Splits. If the Company subdivides (by any stock split, recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to the subdivision will be proportionately reduced and the number of shares of Common Stock issuable upon exercise of each Warrant will be proportionately increased. If the Company combines (by combination, reverse stock split or otherwise) its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to the combination will be proportionately increased and the number of shares of Common Stock issuable upon exercise of each Warrant will be proportionately decreased. Any adjustment under this Section 8(a) shall become effective at the close of business on the date the subdivision or combination becomes effective.

8

(b) Stock Dividends. If the Company declares a dividend or any other distribution upon the Common Stock that is payable in shares of Common Stock or Derivative Securities, the number of shares of Common Stock issuable upon exercise of each Warrant will be proportionately increased and the Exercise Price in effect immediately prior to the declaration of the dividend or distribution will be reduced to the quotient obtained by dividing (i) the number of shares of Common Stock outstanding immediately prior to the declaration multiplied by the then effective Exercise Price by (ii) the total number of shares of Common Stock outstanding immediately after the declaration (assuming the exercise or conversion of any such Derivative Securities for cash (not on a “cashless” basis)).

(c) Adjustment for Property Dividends. If the Company declares a dividend or any other distribution upon the Common Stock that is payable in any of its assets (including cash) or debt securities or any rights, options or warrants to purchase debt securities, assets or other securities of the Company (other than (i) Common Stock pursuant to which another provision of this Section 8 applies or (ii) any dividend or distribution upon a merger or consolidation or sale to which Section 9 applies) (a “Property Dividend”), then and in each such event the Exercise Price for each Warrant in effect immediately prior to the close of business on the date for the determination of the holders of Common Stock entitled to receive such dividend or distribution shall be decreased by the fair market value (as determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive and evidenced by a Board Resolution filed with the Company) of such Property Dividend so distributed for each share of Common Stock.

Any adjustment under this Section 8(c) shall, become effective immediately prior to the opening of business on the day after the date for the determination of the holders of Common Stock entitled to receive a Property Dividend. If the Board of Directors determines the fair market value of any Property Dividend for purposes of this Section 8(c) by reference to the actual or when issued trading market for any securities comprising such Property Dividend, it must in doing so consider the prices in such market over the same period used in computing the Fair Market Value (pursuant to Section 8(e)) per share of Common Stock.

For purposes of clarity, if a declared Property Dividend would have reduced the Exercise Price to an amount below $0, the Exercise Price will be reduced to $0 and any remaining fair market value of the Property Dividend that would have resulted in a reduction of the Exercise Price below $0 shall be reflected in an increase of the number of shares issuable upon exercise of this Warrant pursuant to Section 8(d) hereto.

(d) Adjustment for Property Dividend In Special Circumstances. In the event that the Exercise Price is or has been reduced to $0 or a price that rounds to $0 due to adjustments to the Exercise Price pursuant to Section 8(c) and the Company declares a dividend or any other distribution upon the Common Stock that is a Property Dividend, this Section 8(d) shall apply and the number of shares of Common Stock issuable upon exercise of a Warrant shall be adjusted in accordance with the formula:

9

where:

The adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of stockholders entitled to receive such distribution.

This Section 8(d) does not apply to regular quarterly cash dividends. If any adjustment is made pursuant to this Section 8(d) as a result of the issuance of rights, options or warrants and at the end of the period during which any such rights, options or warrants are exercisable, not all such rights, options or warrants shall have been exercised, this Warrant shall be immediately readjusted as if “F” in the above formula was the fair market value on the Ex Date for such distribution of the indebtedness or assets actually distributed upon exercise of such rights, options or warrants divided by the number of shares of Common Stock outstanding on the ex-dividend date for such distribution. Notwithstanding anything to the contrary contained in this Section 8(d), if “M-F” in the above formula is less than $1.00, the Company may elect to, and if “M-F” or is a negative number, the Company shall, in lieu of the adjustment otherwise required by this Section 8(d), distribute to the holder of a Warrant, upon exercise thereof, the evidences of indebtedness, assets, rights, options or warrants (or the proceeds thereof) which would have been distributed to such holder had such Warrant been exercised (for cash) immediately prior to the record date for such distribution.

(e) Issuance of Common Stock Below Current Fair Market Value. If the Company shall issue or sell shares of Common Stock, or Derivative Securities containing the right to subscribe for or purchase shares of Common Stock to someone other than the Holder, at a price per share (determined, in the case of such Derivative Securities, by dividing (A) the total amount receivable by the Company in consideration of the issuance and sale of such Derivative Securities, plus the total consideration, if any, payable to the Company upon exercise, conversion or exchange thereof, by (B) the total number of shares of Common Stock covered by such Derivative Securities) that is lower than the then current Fair Market Value (defined below) per share of Common Stock in effect immediately prior to such sale or issuance, then (1) the number of shares of Common Stock issuable upon exercise of each Warrant shall be increased by adding the number of shares of Common Stock theretofore issuable upon exercise of such Warrant to the product of (x) the Cheap Stock Issued (defined below), multiplied by (y) the Ownership Ratio (defined below); and (2) the Exercise Price shall be reduced by multiplying the then current Exercise Price by a fraction of which, the numerator shall be the number of shares of Common Stock issuable upon exercise of each Warrant immediately prior to such sale or issuance and the denominator of which shall be the number of shares of Common Stock issuable upon exercise of such Warrant after adjustment pursuant to clause (1), above. Such adjustment shall be made successively whenever any such sale or issuance is made.

10

“Cheap Stock Issued” shall be the number of additional shares of Common Stock issued or offered by the Company for subscription or purchase as described above minus the number of shares of Common Stock that the aggregate offering price of the total number of shares of Common Stock so offered would purchase at the then current Fair Market Value per share of Common Stock.

“Ownership Ratio” shall be a fraction, the numerator of which shall be the number of shares of Common Stock issuable upon exercise of each Warrant prior to such time, and the denominator of which shall be the number of shares of Common Stock then outstanding on the date of issuance or sale of such shares of Common Stock or such Derivative Securities. For purposes of such adjustments, the shares of Common Stock which the holder of any such Derivative Securities shall be entitled to subscribe for or purchase (assuming the exercise or conversion of any such Derivative Securities for cash (not on a “cashless” basis)) shall be deemed to be issued and outstanding as of the date of the sale and issuance of the rights, warrants or convertible or exchangeable securities.

“Fair Market Value” shall be equal to a discount of 10% to the average VWAP of the Common Stock for the 30 days preceding the issuance of such shares of Common Stock, or Derivative Securities.

“VWAP” means, 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 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 for trading as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time); (b) if the OTC Bulletin Board is not a Trading Market, the volume weighted average price 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 quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the “Pink Sheets” published by 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, the fees and expenses of which shall be paid by the Company.

11

“Trading Market” means the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the American Stock Exchange, The Nasdaq Capital Market, The Nasdaq Global Market, The Nasdaq Global Select Market, the New York Stock Exchange, the OTC Bulletin Board or the Pink Sheets.

(f) Other Adjustments.

(i) Notwithstanding anything to the contrary contained in this Section 8, if, at any time while a Warrant is outstanding, the Company shall issue or sell shares of Common Stock, or Derivative Securities to someone other than the Holder, at a price per share (determined, in the case of such Derivative Securities, by dividing (A) the total amount receivable by the Company in consideration of the issuance and sale of such Derivative Securities, plus the total consideration, if any, payable to the Company upon exercise, conversion or exchange thereof, by (B) the total number of shares of Common Stock covered by such Derivative Securities) that is lower than the Exercise Price, the Company shall adjust the Exercise Price and number of shares into which each Warrant is convertible so that such Warrant shall be exercisable for the same percentage of the outstanding Common Stock (on an “as converted” basis) following the issuance or sale of such other shares of Common Stock or Derivative Securities for the same aggregate consideration prior to such adjustment; provided, that such adjustments shall only be made for the benefit of the Holder of this Warrant.

(ii) Notwithstanding anything to the contrary contained in this Section 8, if, at any time while a Warrant is outstanding, the number of shares underlying any Derivative Security, and/or the exercise or conversion price of such Derivative Security adjusts or would have adjusted for any reason (including as a result of the issuance of a Warrant) and the terms, manner or method of such adjustment are more favorable than the adjustment provisions contained in this Section 8, the Company shall adjust the Exercise Price and/or number of shares into which each Warrant is convertible in order to give the Holder the benefit of the more favorable terms, manner and/or method; provided, that no adjustment shall be made pursuant to this Section 8(f)(ii): (A) if an adjustment is otherwise required pursuant to another provision contained in this Section 8; (B) if the additional adjustment that may be required by this Section 8(f)(ii) would not require a decrease or increase of at least 1% in the Exercise Price then in effect or the number of shares of Common Stock issuable upon exercise of a Warrant; provided, that any adjustments that, by reason of this clause (B) of Section 8(f)(ii), are not required to be made shall be carried forward and taken into account in any subsequent adjustment; or (C) solely as a result of an adjustment pursuant to: (1) Section 7(f) of those certain warrants to purchase Common Stock each dated December 31, 2008 and issued to purchasers of shares of Series C Preferred Stock of the Company in connection with the purchase of such shares of Series C Preferred Stock or (2) Section 7(f)(ii) of those certain warrants issued to purchase Common Stock composing the Series D Units. For the avoidance of doubt, the Exercise Price and number of shares of Common Stock issuable upon exercise of each Warrant shall be adjusted so that such Warrant shall be exercisable for the same percentage of the outstanding Common Stock (on a fully diluted basis) following the adjustment of such other Derivative Security pursuant to the foregoing sentence for the same aggregate consideration prior to such adjustment; provided, that following such adjustment, if the exercise price of such other Derivate Security is less than the Exercise Price, the Exercise Price shall be reduced to the same exercise price as the Derivative Security; provided further, that such adjustments shall only be made for the benefit of the Holder of a Warrant.

12

Payment of the Exercise Price may be made, at the option of the holder of the Warrant and subject to conditions set forth herein and in the Warrant Agreement, by the following methods (or any combination thereof): (1) in cash or by wire transfer of immediately available funds; (2) by means of a cashless exercise pursuant to Section 4(c) of the Warrant Agreement; (3) by surrender of all or a portion (as appropriate) of such holder’s Series E Preferred Shares pursuant to Section 4(d) of the Warrant Agreement; or (4) by applying the Exercise Price Accrual credited to the account of such solder pursuant to Section 4(e) of the Warrant Agreement.

Upon due presentment for registration of transfer of the Warrant Certificate at the office of the Company, a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any applicable tax or other government charge.

The Company may deem and treat the registered holder as the absolute owner of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the registered holder, and for all other purposes, and the Company shall not be affected by any notice to the contrary.
