             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

The unaudited Pro Forma Consolidated Balance Sheet of Omnicare, Inc. (the
"Company") as of June 30, 1997 gives effect to the acquisition of American
Medserve Corporation ("AMC") as if it had occurred as of June 30, 1997. The
unaudited Pro Forma Consolidated Statements of Income of the Company for the
year ended December 31, 1996 and for the six months ended June 30, 1997 give
effect to the acquisition of AMC as if it had occurred on January 1, 1996.

The acquisition of AMC was accounted for under the purchase method of
accounting. The total purchase price was allocated to the tangible and
identifiable intangible assets, and liabilities based on the Company's
management's estimate of their fair values. The excess of cost over the fair
value of the net assets acquired was recorded as goodwill. The allocation of the
purchase price may be adjusted in accordance with Statement of Financial
Accounting Standards No. 38, "Accounting for Preacquisition Contingencies of
Purchased Enterprises," to the extent that actual amounts differ from
management's current estimates. Management does not expect that any such
adjustment would have a material impact on the pro forma information.

The pro forma information has been prepared by the Company based on the
consolidated financial statements of the Company and AMC included in their
respective 1996 Forms 10-K and June 30, 1997 Forms 10-Q. The pro forma
information is presented for illustration purposes only and does not purport to
be indicative of the combined financial condition or results of operations that
actually would have occurred if the acquisition of AMC had been effected at the
dates indicated or to project future financial condition or results of
operations for any future period. The pro forma information gives effect only to
the adjustments set forth in the accompanying notes and does not reflect any
synergies anticipated by the Company's management as a result of the
acquisition, in particular improvements in gross margin attributable to the
Company's purchasing leverage associated with purchases of pharmaceuticals and
the elimination of duplicate payroll and other operating expenses. Therefore,
management believes that the pro forma financial information is not necessarily
indicative of future performance. The pro forma information should be read in
conjunction with the Company's consolidated financial statements and related
notes thereto included in its 1996 Form 10-K (as amended on Form 10-K/A dated
August 6, 1997) and its June 30, 1997 Form 10-Q, and the consolidated financial
statements of AMC and related notes thereto included in its 1996 Form 10-K and 
June 30, 1997 Form 10-Q, which have been incorporated by reference in the 
Company's current report on Form 8-K dated September 12, 1997.

               Notes to Unaudited Pro Forma Financial Information
                             (dollars in thousands)

Balance Sheet
- -------------
(a)    On September 16, 1997, Omnicare, Inc. (the "Company") completed the
       acquisition of all outstanding shares of American Medserve Corporation
       ("AMC") for a cash purchase price of approximately $223,000. The
       acquisition was accounted for under the purchase method of accounting and
       the total consideration to be paid, including estimated transaction costs
       of $10,000, was allocated to the tangible and identifiable intangible
       assets and liabilities acquired based on their estimated fair values at
       the date of acquisition. The excess of the acquisition cost over the fair
       value of the net assets acquired was recorded as goodwill. For purposes
       of the unaudited pro forma balance sheet, the acquisition and related
       purchase accounting is assumed to have been recorded as of June 30, 1997.

(b)    On the closing date, the Company drew down $250,000 from its $400,000
       revolving credit agreement to fund the cash purchase price for the AMC
       stock, the related estimated transaction costs and the repayment of
       approximately $16,700 of AMC's debt on the closing date. As of June 30,
       1997, such debt totalled $16,520 and for purposes of the pro forma
       balance sheet, that amount is assumed to have been repaid as of June 30,
       1997. Accordingly, the total cash paid as of June 30, 1997 is assumed to
       have been $249,520, which results in $480 of additional cash balances as
       of June 30, 1997.

(c)    To eliminate the AMC deferred debt issuance costs as of June 30, 1997
       relating to the debt repaid by the Company at closing.

(d)    To eliminate AMC's existing goodwill as of June 30, 1997.

(e)    To record the estimated AMC employees' severance cost liability accrued
       in accordance with EITF 95-3 ($5,500) and the estimated transaction costs
       incurred by AMC that became payable on the closing date ($2,700).

(f)    To eliminate the stockholders' equity accounts of AMC.

Income Statement
- ----------------

(g)    To reflect amortization of the goodwill of $218,677 recorded in
       connection with the purchase of AMC on a straight-line basis over 40
       years.

(h)    To eliminate AMC's historical goodwill amortization.

(i)   To adjust interest expense to

                                                                       12 Months        6 Months

(i)   eliminate historical interest expense on the AMC debt repaid
       at closing                                                        $ (2,586)       $    (393)
(ii)  record interest expense at 5.9375% (the current actual rate
       on the borrowing) on the $250 million of debt drawn down
       by the Company at closing (annual interest expense would
       change by approximately $313 for each 1/8% change in
       the interest rate).                                                 14,844             7,422

                                                                         $ 12,258         $   7,029
                                                                         ========         =========



(j)    To eliminate AMC's historical amortization of debt issuance costs,
       included in selling, general and administrative expenses.

(k)    To reclassify certain general and administrative expenses of AMC to cost
       of sales in order to reflect cost of sales consistently with the Company.

(l)    Tax effect of pro forma adjustments, excluding the portion of goodwill
       amortization that is not tax deductible, at the Company's effective tax
       rate of approximately 40% which is not materially different than the
       combined federal and state statutory rates.

(m)    Represents (1) a noncash, nonrecurring charge of $2,500 (with no tax
       benefit) related to the sale of 310,208 shares of common stock of AMC to
       certain directors and officers at a price less than the initial public
       offering price of the common stock on November 13, 1996, and the
       conversion of options to purchase shares of common stock of certain
       subsidiaries into options to purchase 146,635 shares of common stock of
       AMC at a weighted average exercise price less than the initial public
       offering price of the common stock on November 13, 1996, (2) a charge of

       services agreement with an affiliate of AMC's principal stockholder and
       (3) a charge of $200 ($100 net of tax) related to special bonuses paid to
       management in connection with AMC's initial public offering.
