 (1) For
purposes of calculating the dilutive loss per common share for the years ended
December 31, 2009, 2008 and 2007, the assumed exercise of dilutive securities
(in-the-money stock options) is not taken into consideration, as its effect is
anti-dilutive. Had these been exercised 0.4 million, zero and 0.4 million
additional shares of common stock would have been assumed outstanding for each
of the years in the years ended December 31, 2009, 2008 and 2007,
respectively.
 
 (2) For
purposes of calculating the dilutive loss per common share for the years ended
December 31, 2009, 2008 and 2007, the assumed conversion of the 5.45%
Convertible Notes due 2011 and the 5.45% Convertible Notes due 2010 is not taken
into consideration as their effect is anti-dilutive. Had the 5.45% Convertible
Plus Cash Notes due 2007 and the 5.45% Convertible Notes due 2010 been
converted, 1.2 million, 0.6 million and 1.5 million additional shares of common
stock would have been assumed outstanding for each of the years in the years
ended December 31, 2009, 2008 and 2007, respectively.
 
 (3) For
purposes of calculating the dilutive loss per common share for the years ended
December 31, 2009, 2008 and 2007, the assumed release or dilutive restricted
stock units is not taken into consideration as their effect is anti-dilutive.
Had the restricted stock units been released, 0.6 million, 0.1 million and zero
additional shares of common stock would have been assumed outstanding for each
of the years in the years ended December 31, 2009, 2008 and 2007,
respectively.
