(a)  The contingent value rights (the "CVRs") matured on July 7, 1995.  
     The Company paid  approximately  $83 million in cash of approximately  
     $1.44 per CVR to settle its obligation.

(b)  The Preferred Stock and related dividend requirement had an anti-dilutive
     effect on earnings per share for the third quarter and nine months ended
     September 30, 1995 and the nine months ended September 30, 1994, and
     therefore, were excluded from the fully diluted earnings per share
     computation.
