(1)  The pro forma adjustments give effect to increased interest expense, as 
     if such transactions had taken place January 1, 1994 as a result of the
     issuance of $75 million of the Senior Notes due 2007 at a pro forma annual 
     interest rate of 8.50% and $125 million of Senior Notes due 2005 at a pro
     forma annual interest rate of 8.375% and the application of proceeds to
     reduce the Company's debt under its $350 million revolver and uncommitted
     and unsecured lines of credit.
