(11) Debt
    
             Our debt consists of the following:
    
   
      (a) 3.25% Convertible Notes due 2011
    
             In October 2004, we issued $230,000 in aggregate principal amount of 3.25% Convertible Notes
   due October 15, 2011 (the “3.25% Notes”), which are convertible, at the option of the holder, into
   shares of our common stock at any time at a conversion rate of 188.6792 shares of common stock for
   each $1,000 principal amount, or $5.30 per share of common stock, subject to certain adjustments.
   Interest is payable semi-annually on April 15 and October 15 of each year. The obligations under
   the 3.25% Notes are not secured by any of our assets.
    
             In 2011, we purchased $168,113 of the outstanding 3.25% Notes at prices between 100.75% and
   101% of the principal amount plus accrued interest. We recognized a loss on extinguishment of debt
   for the 3.25% Notes of $1,212 for the three months ended June 30, 2011 and $2,291 for the six
   months ended June 30, 2011, which consists primarily of cash premiums paid, unamortized discount
   and deferred financing fees.

   year at a rate of 8.75% per annum. The 8.75% Notes mature on April 1, 2015. The 8.75% Notes were
   issued for $786,000, resulting in an aggregate original issuance discount of $14,000. Substantially
   all of our domestic wholly-owned subsidiaries guarantee our obligations under the 8.75% Notes on a
   senior unsecured basis.
    
        (c) 9.75% Senior Secured Notes due 2015

   deferred financing fees and repayment premium to Loss on extinguishment of debt and credit
   facilities, net, in our 2010 consolidated statement of operations. The remainder of the 11.25%
   Notes of $36,685 was purchased in January 2011 for an aggregate purchase price of $40,376. A loss

   exchangeable at any time at the option of the holder into shares of our common stock at an initial
   exchange rate of 533.3333 shares of common stock per $1,000 principal amount of Exchangeable Notes,
   which is equivalent to an approximate exchange price of $1.875 per share of common stock.

        Covenants and Restrictions
    
             Our debt generally requires compliance with certain covenants that restrict our ability to,
   among other things, (i) incur additional indebtedness unless our consolidated leverage ratio would
   be no greater than 6.00 to 1.00 after the incurrence of the indebtedness, (ii) incur liens, (iii)
   pay dividends or make certain other restricted payments, investments or acquisitions, (iv) enter
   into certain transactions with affiliates, (v) merge or consolidate with another person, (vi) sell,
   assign, lease or otherwise dispose of all or substantially all of our assets, and (vii) make
   voluntary prepayments of certain debt, in each case subject to exceptions.
    
             Under our debt agreements, the following generally constitute an event of default: (i) a
   default in the payment of interest; (ii) a default in the payment of principal; (iii) failure to
   comply with covenants; (iv) failure to pay other indebtedness after final maturity or acceleration
   of other indebtedness exceeding a specified amount; (v) certain events of bankruptcy; (vi) a
   judgment for payment of money exceeding a specified aggregate amount; and (vii) voidance of
   subsidiary guarantees, subject to grace periods where applicable. If an event of default occurs
   and is continuing, our debt could become immediately due and payable.
    
             At June 30, 2011, we were in compliance with our debt covenants.
