Issuance of the New Warrant. The issuance of the New Warrants will be duly authorized and, upon the execution of this letter agreement by the undersigned, will be duly and validly issued, fully paid and nonassessable, free and clear of all liens imposed by the Company, and the shares issuable upon exercise of the New Warrant (the “New Warrant Shares”), when issued in accordance with the terms of the New Warrant, will be validly issued, fully paid and nonassessable, free and clear of all liens imposed by the Company. The Company will reserve from its duly authorized capital stock a number of shares of Common Stock for issuance of the New Warrant Shares in full.

  The New Warrant and New Warrant Shares may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of New Warrant or New Warrant Shares other than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate of the undersigned or in connection with a pledge, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred New Warrant and New Warrant Shares under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this letter agreement.

  The undersigned agrees to the imprinting, so long as is required by this Section (i), of a legend on any of the New Warrant and New Warrant Shares in the following form:

 Certificates evidencing the New Warrant Shares shall not contain any legend (including the legend set forth in Section (f)(ii) hereof), (i) while a registration statement covering the resale of such security is effective under the Securities Act, (ii) following any sale of such New Warrant Shares pursuant to Rule 144,  or (iii) if such New Warrant Shares are eligible for sale under Rule 144. The Company shall cause its counsel to issue a legal opinion to its transfer agent (if required by the transfer agent) and the undersigned (if requested by the undersigned) in connection with the removal of the legend hereunder. If all or any portion of a New Warrant is exercised at a time when there is an effective registration statement to cover the resale of the New Warrant Shares, or if such New Warrant Shares may be sold under Rule 144, then such New Warrant Shares shall be issued free of all legends. The Company agrees that following such time as such legend is no longer required under this clause (iii), it will, no later than the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined below) following the delivery by Holder to the Company or the Transfer Agent of a certificate representing Warrant Shares, as applicable, issued with a restrictive legend (such date, the “Legend Removal Date”), deliver or cause to be delivered to the undersigned a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the transfer agent that enlarge the restrictions on transfer set forth in this Section (f). Certificates for New Warrant Shares subject to legend removal hereunder shall be transmitted by the transfer agent to the undersigned by crediting the account of the undersigned’s prime broker with the Depository Trust Company System as directed by the undersigned. “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of a certificate representing Warrant Shares issued with a restrictive legend.

  In addition to such undersigned’s other available remedies, the Company shall pay to the undersigned, in cash, (i) as partial liquidated damages and not as a penalty, for each $1,000 of New Warrant Shares (based on the VWAP of the Common Stock on the date such Securities are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section (f)(iii), $10 per Trading Day (increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue) for each Trading Day after the Legend Removal Date until such certificate is delivered without a legend and (ii) if the Company fails to (a) issue and deliver (or cause to be delivered) to the undersigned by the Legend Removal Date a certificate representing the Securities so delivered to the Company by such undersigned that is free from all restrictive and other legends and (b) if after the Legend Removal Date such undersigned purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by such undersigned of all or any portion of the number of shares of Common Stock, or a sale of a number of shares of Common Stock equal to all or any portion of the number of shares of Common Stock that such undersigned anticipated receiving from the Company without any restrictive legend, then, an amount equal to the excess of such undersigned’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including brokerage commissions and other out-of-pocket expenses, if any) (the “Buy-In Price”) over the product of (A) such number of New Warrant Shares that the Company was required to deliver to such undersigned by the Legend Removal Date multiplied by (B) the lowest closing sale price of the Common Stock on any Trading Day during the period commencing on the date of the delivery by such undersigned to the Company of the applicable New Warrant Shares (as the case may be) and ending on the date of such delivery and payment under this clause (ii).

Public Information Failure. At any time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all of the New Warrant Shares may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144, if there is no effective registration statement covering the resale of all of the New Warrant Shares and the Company (i) shall fail for any reason to satisfy the current public information requirement under Rule 144(c) or (ii) has ever been an issuer described in Rule 144(i)(1)(i) or becomes an issuer in the future, and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information Failure”) then, in addition to the undersigned’s other available remedies, the Company shall pay to the undersigned, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the New Warrant Shares, an amount in cash equal to two percent (2.0%) of the aggregate Exercise Price of the undersigned’s New Warrant on the day of a Public Information Failure and on every thirtieth (30th) day (pro-rated for periods totaling less than thirty days) thereafter until the earlier of (a) the date such Public Information Failure is cured and (b) such time that such public information is no longer required  for the undersigned to transfer the New Warrant Shares pursuant to Rule 144.  The payments to which the undersigned shall be entitled pursuant to this Section (g) are referred to herein as “Public Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments are incurred and (ii) the third (3rd) Business Day after the event or failure giving rise to the Public Information Failure Payments is cured.  In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein shall limit the undersigned’s right to pursue actual damages for the Public Information Failure, and the undersigned shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

Listing of Common Stock. The Company shall apply to list or quote all of the New Warrant Shares on Nasdaq and promptly secure the listing of all of the New Warrant Shares on Nasdaq.

Registration Statement.  As soon as practicable (and in any event within ten (10) calendar days of the date of this Agreement), the Company shall file a registration statement on Form S-3 (or other appropriate form if the Company is not then S-3 eligible) providing for the resale by the Holders of the New Warrant Shares issued and issuable upon exercise of the New Warrants.  The Company shall use commercially reasonable efforts to cause such registration to become effective on or prior to the 30^th calendar day after the initial filing date and to keep such registration statement effective at all times until no Holder owns any New Warrants or New Warrant Shares issuable upon exercise thereof.

Subsequent Equity Sales.  From the date hereof until 45 days following the date hereof, neither the Company nor any Subsidiary shall (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents or (ii) file any registration statement or any amendment or supplement thereto, in each case other than the registration statement registering the New Warrant Shares or a registration statement on Form S-8.  Notwithstanding the foregoing, this Section (j) shall not apply in respect of an Exempt Issuance.  As used herein, “Exempt Issuance” means the issuance of (a) shares of Common Stock or options to employees, officers or directors of the Company pursuant to any stock or option plan duly adopted for such purpose by a majority of the non-employee members of the Board of Directors or a majority of the members of a committee of non-employee directors established for such purpose, (b) securities upon the exercise or exchange of or conversion of any Securities issued hereunder and/or other securities exercisable or exchangeable for or convertible into shares of Common Stock issued and outstanding on the date of this letter agreement, provided that such securities have not been amended since the date of this letter agreement to increase the number of such securities or to decrease the exercise price, exchange price or conversion price of such securities (except for such decreases in exercise, exchange or conversion price in accordance with the terms of such securities) or to extend the term of such securities, (c) upon the exercise or exchange of or conversion of any securities issued pursuant to this letter agreement, and (d) securities issued pursuant to acquisitions or strategic transactions approved by a majority of the disinterested directors of the Company, provided that such securities are issued as “restricted securities” (as defined in Rule 144) and carry no registration rights that require or permit the filing of any registration statement in connection therewith until the registration statement registering all of the New Warrant Shares is declared effective, and provided that any such issuance shall only be to a Person (or to the equity holders of a Person) which is, itself or through its subsidiaries, an operating company or an owner of an asset in a business synergistic with the business of the Company and shall provide to the Company additional benefits in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities.

From the date hereof until the one-year anniversary of the date hereof, the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a Variable Rate Transaction.  “Variable Rate Transaction” means a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive, additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based upon, and/or varies with, the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit or an “at-the-market offering,” whereby the Company may issue securities at a future determined price, regardless of whether shares pursuant to such agreement have actually been issued and regardless of whether such agreement is subsequently canceled; provided, however, that, after the six month anniversary of the Closing Date, the entry into and/or issuance of shares of Common Stock in an “at the market” offering shall not be deemed a Variable Rate Transaction.  The Holder shall be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages.
