*  During the years ended December 31, 1992 and 1991, 1,382,551 and 3,140,304
   shares of the Series A Preferred Stock had been converted into 1,244,261 and
   2,826,256 shares of common stock, respectively.  If these conversions had
   occurred at the beginning of the respective years, primary net income per
   share would have been $3.32 and $2.60 per share for the year ended December
   31, 1992 and 1991, respectively.

** The Series B Preferred Stock is not considered convertible for purposes of
   calculating fully diluted net income per share as it is currently
   antidilutive.
