Settlement:
  March 20, 2007
 
   
U.S. federal income tax considerations:
  Each holder will be deemed to have agreed in the indenture, for United States federal income tax purposes, to treat the notes as “contingent payment debt instruments” and to be bound by our application of the U.S. Department of Treasury regulations that govern contingent payment debt instruments. The comparable yield is 8.250%.
 
   
Adjustment to conversion rate upon a fundamental change:
  If a fundamental change described in any of paragraphs (1) and (2) of the definition of such term occurs and a holder elects to convert its notes in connection with such fundamental change, the issuer will increase the applicable conversion rate for the notes surrendered for conversion by a number of additional shares of common stock (the “make-whole shares”). The following table sets forth the hypothetical stock price, effective date and number of make-whole shares per $1,000 principal amount of notes:
