Earlier today, we provided Lincoln Park Capital Fund, LLC ("LPC") with notice of termination of our Purchase Agreement dated May 27, 2011.  The Purchase Agreement allowed us to require LPC to purchase up to $30 million of our common stock from time to time, and also allowed us to terminate the Purchase Agreement for any reason or for no reason with one business day's notice to LPC.  There are no early termination penalties, however, certain provisions in the Purchase Agreement survive termination, as more fully described in the Purchase Agreement, which was attached as an Exhibit to our Form 8-K filed with the SEC on May 31, 2011.  The notice of termination is attached as Exhibit 10.15 to this Form 8-K and incorporated by reference herein.
