SELLING STOCKHOLDERS
 
The following table sets forth the names of the selling stockholders who may sell their shares under this prospectus from time to time.  The selling stockholders are not obligated to sell any of the shares offered by this prospectus.  The number of shares sold by each selling stockholder may depend on a number of factors, such as the market price of our common stock.
 
We are registering 8,373,246 shares of our common stock for resale by the selling stockholders.  We agreed to file a registration statement under the Securities Act of 1933, as amended (the “Securities Act”) with the Securities and Exchange Commission, of which this prospectus is a part, with respect to the resale of:
 
·  
1,858,714 shares of common stock and 1,666,667 shares of common stock issuable upon exercise of warrants issued to investors in our private offering completed on April 16, 2007;
 
·  
354,960 shares of common stock issuable upon exercise of warrants issued to the placement agents with respect to the private offering completed on April 16, 2007;
 
·  
2,621,365 shares of our common stock and 1,300,000 shares of our common stock issuable upon exercise of warrants and options owned by our Chairman and Chief Executive Officer and related parties;
 
 
 

 
·  
516,500 shares of common stock issued upon exercise of warrants issued in our private offering completed in December 2004 and January 2005 and to assignees of the placement agent in connection with that offering; and
 
·  
5,040 shares of common stock issued upon exercise of warrants issued to an assignee of the placement agent in connection with our private offering completed on April 16, 2007.
 
The number of shares of our common stock shown in the following table as being offered by the selling stockholders do not include such presently indeterminate number of additional shares of our common stock that may be issuable as a result of stock splits, stock dividends and similar transactions.  Pursuant to Rule 416 under the Securities Act, however, such shares are included in the Registration Statement of which this prospectus is a part.
 
The selling stockholders may sell any or all of their shares listed below from time to time. Accordingly, we cannot estimate how many shares the selling stockholders will own upon consummation of any such sales.  Also, the selling stockholders may have sold, transferred or otherwise disposed of all or a portion of their shares since the date on which the information was provided in transactions exempt from the registration requirements of the Securities Act.
 
Of the selling stockholders listed in the table below, Eric Singer, Hilary Bergman, Brad Reifler, Jack Brimberg, Theodore J. Marolda, Jay Tomlinson and Steven Heinemann are believed by us to be affiliates of broker-dealers, who purchased the shares in the ordinary course of business and at the time of the purchase of the securities to be resold, such selling stockholders did not have any agreements or understandings, directly or indirectly, with any person to distribute the securities.
 
None of the selling stockholders has had a material relationship with us within the past three years other than as a result of the ownership of our securities except: (i) Corey M. Horowitz is our Chairman and Chief Executive Officer and (ii) Mr. Horowitz and Laurent Ohana serve on our board of directors.
