(1) We believe that any excess of the total amount of registered sales by selling securityholders is the result of (i) sales by selling securityholders who previously registered their securities in unregistered exempt transactions and the subsequent registration by the purchasers thereof, or (ii) registration by selling securityholders who had acquired their securities in a previously registered transaction. (2) This selling securityholder is a registered broker-dealer and, therefore, is deemed an underwriter by the SEC. Lehman Brothers Inc. was the initial purchaser of the notes. In addition, Lehman Brothers Inc. and its affiliates have in the past provided and may from time to time in the future provide certain commercial banking, financial advisory, investment banking and other services for us for which they have received and will be entitled to receive separate fees. Investing in the notes and the underlying shares of common stock involves significant risks. See Risk Factors beginning on page 5 of the prospectus. Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus supplement or the prospectus. Any representation to the contrary is a criminal offense. The date of this prospectus supplement is July 18, 2006. |
