  of letters of credit that can be issued to $200 million, and the amount of available 
  borrowings under the Senior Credit Facility is reduced by any outstanding letters 
  of credit. At December 31, 2004, the Company had provided a $50 million letter 
  of credit to support the Economic Development Corporation of the City of Detroit 
  bonds referred to above, which are a liability of the Company.

  relate to routine matters incidental to its business. Management does not believe 
  that the outcome of such proceedings will have a material adverse effect on the
