(a)  The $345.0 million of Convertible Debentures which are convertible into 8.7
     million shares at $39.60 per share were outstanding during the three and
     six months ended June 30, 2002 and 2001, but were not included in the
     computation of diluted EPS because the impact was anti-dilutive.

(b)  During the three and six months ended June 30, 2002 and 2001, the
     anti-dilutive effect associated with options and warrants was excluded
     from the computation of diluted earnings per share, since the exercise
     price of these options and warrants was greater than the average market
     price of the Company's common stock during these periods. The aggregate
     anti-dilutive stock options and warrants excluded for the quarter ended
     June 30, 2002 and 2001 totaled 4.2 million and 3.9 million, respectively.
     Further, 4.1 million and 3.9 million anti-dilutive options and warrants
     were excluded from the year-to-date June 30, 2002 and 2001, respectively.

(c)  In accordance with the adoption of Statement of Financial Accounting
     Standards No. 142, "Goodwill and Other Intangible Assets," Omnicare
     discontinued amortization of goodwill as of January 1, 2002. Accordingly,
     no goodwill amortization was recorded during the three and six months ended
     June 30, 2002. Goodwill amortization during the three and six months ended
     June 30, 2001 totaled $8.3 million before taxes ($5.2 million after taxes,
     or $0.05 per basic and diluted share) and $16.5 million before taxes ($10.2
     million after taxes, or $0.11 per basic and diluted share), respectively.
