         Neither the Parent Company nor the Borrower shall or shall permit any
         of its Subsidiaries to sell or issue any shares of stock of any class

         Company and the Borrower are permitted to incur such Indebtedness
         under the Senior Indenture (because either (i) such Indebtedness will
         constitute "Permitted Indebtedness" under the Senior Indenture or (ii)
         such Indebtedness may be incurred without violation of the then
         applicable Consolidated Interest Coverage Ratio set forth in the
