(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 months
     ended March 31, 2002 and 2001, but were not included in the computation of
     diluted EPS because the impact was anti-dilutive.

(b)  During the three months ended March 31, 2002 and 2001, the anti-dilutive
     effect associated with options and warrants were 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 March 31, 2002
     and 2001 totaled 3.8 million and 3.9 million, 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 first quarter of 2002.
     Goodwill amortization in the first quarter of 2001 totaled $8.2 million
     before taxes ($5.1 million after taxes, or $0.05 per basic and diluted
     share).
