None of the selling securityholders nor any of their affiliates, officers, directors or principal equity holders has held any position or office or has had any material relationship with us within the past three years. UBS Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated have in the past and may in the future provide financial advisory and other services to us and our affiliates.  The selling securityholders purchased all of the notes in private transactions on or after June 28, 2006. All of the notes were “restricted securities” under the Securities Act prior to this registration.

Information concerning the selling securityholders may change from time to time and any changed information will be set forth in supplements to this prospectus if and when necessary. In addition, the conversion rate and therefore, the number of shares of common stock issuable upon conversion of the notes, is subject to adjustment under certain circumstances. Accordingly, the number of shares of common stock into which the notes are convertible may increase or decrease.
