                          PROSPECTUS SUPPLEMENT NO. 10
                     (To Prospectus dated December 22, 2005)


     The following information amends and restates the "Selling Stockholders"
table contained in the Prospectus dated December 22, 2005, as supplemented (the
"Prospectus") relating to the resale from time to time of up to 15,786,256
shares of our common stock by certain persons ("Selling Stockholders"). All
capitalized terms used herein which are not otherwise defined have the meaning
ascribed to them in the Prospectus. The "Selling Stockholders" table is being
amended primarily to reflect the exercise of warrants to purchase 1,352,152
shares of common stock and the resale of 760,814 of such shares and the
expiration of certain outstanding warrants. Accordingly, all references in the
Prospectus to the number of shares offered for resale by the Selling
Stockholders shall be amended to 15,786,256 shares of our common stock. In
addition, certain information in the Selling Stockholders table has changed
since the effective date of the Registration Statement underlying the
Prospectus.

This prospectus supplement should be read in conjunction with the Prospectus and
the prior prospectus supplements, and may not be delivered or utilized without
the Prospectus and the prior prospectus supplements. This prospectus supplement
is qualified by reference to the Prospectus, except to the extent that the
information provided by this prospectus supplement supersedes the information
contained in the Prospectus.

The securities offered by the Prospectus involve a high degree of risk. You
should carefully consider the "Risk Factors" referenced on page 7 of the
Prospectus in determining whether to purchase the common stock.

The date of this prospectus supplement is July 21, 2006.


                              SELLING STOCKHOLDERS

     The following table sets forth information, as of July 21, 2006, with
respect to the common stock beneficially owned by each selling stockholder. 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 15,835,170 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:

   o   2,685,000 shares of our common stock and 2,063,750 shares of our common
       stock issuable upon exercise of warrants issued in our private offering
       completed in December 2004 and January 2005;

   o   9,048,017 additional shares of our common stock issued to certain of our
       stockholders; and

   o   1,989,489 shares of our common stock issuable upon exercise of certain
       other outstanding warrants and options, all as disclosed in the table
       below.

     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, Singer Opportunity
Fund, L.P., Singer Fund, L.P., Hilary Bergman, Steven Goldfarb, Patrick McBrien,
Scott Zelnick and Steven Heineman 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, (ii) Mr. Horowitz, Robert Graifman and Laurent Ohana serve as our
directors, and (iii) CHM Capital Management Corp., the sole shareholder,
director and officer of which is Mr. Horowitz, performed consulting services for
us prior to Mr. Horowitz becoming our Chairman and Chief Executive Officer in
December 2003.
