- --------
(a) The Zero Coupon Convertible Subordinated Notes were retired during 1992.
    1991 versus 1990 convertible debt was outstanding for the entire year; as a
    result, conversion was antidilutive, and no adjustment was required in
    1991.
(b) In 1992, these adjustments are not considered for the fully diluted
    earnings per share calculation due to their antidilutive effect.
