(“NeighborCare”) are included in the Company’s consolidated results from the date of acquisition of July 28, 2005.

(2) This column is derived from NeighborCare’s unaudited statement of operations for the period from January 1, 2005 to July 27, 2005.

(3) This column is derived from the audited consolidated financial statements of the Company for the year ended December 31, 2004.

(4) This column is derived from the audited consolidated financial statements of NeighborCare for the year ended September 30, 2004.

Pro Forma Adjustments:

(a) To reclassify historical NeighborCare balances to conform with the Company’s presentation, which includes the following:

(a1) To reclassify NeighborCare’s delivery expenses out of cost of sales and into selling, general and administrative expenses.

(a2) To reclassify NeighborCare’s nonproduction depreciation and amortization to selling, general and administrative expenses.

(b) To record the net increase in amortization expense related to the estimated increase in separately identifiable intangible assets of approximately $153 million, with an estimated useful life of twelve years, resulting from the NeighborCare acquisition. The Company is currently having a valuation of identifiable intangible assets performed by an independent valuation firm, so the final identifiable intangible assets and related amortization expense are subject to change based on the outcome of the valuation work.

(c) To (increase) / decrease interest expense for the following:

	Nine Months Ended September 30, 2005			Twelve Months Ended December 31, 2004
(i)       Reduce interest expense for the payoff of certain Omnicare, Inc. and NeighborCare, Inc. debt, relating to refinancing activities associated with the NeighborCare acquisition, as if it had been repaid as of January 1, 2004. This reduction includes normal interest expense, amortization of deferred financing fees and commitment fees; less deferred financing fees written off	$	26,774		$	24,068
(ii)      Record interest expense at 4.49% for the five-year revolving credit facility and the five-year senior term A facility, and 4.55% for the 364-day facility, relating to the $2,225,232 of debt borrowed on the $2.9 billion commitment letter to fund the NeighborCare acquisition, and assumed to be outstanding at January 1, 2004 (annual interest expense would change by approximately $22,252 for each 1% change in the interest rate)		(57,415	)		(100,753	)
(iii)    Record interest expense for the commitment fee on the undrawn portion of the Company’s five-year revolving credit facility component of its new credit facilities at an assumed rate of 0.175%		(673	)		(1,181	)
(iv)     Record amortization of new debt issuance costs as if the debt was outstanding as of January 1, 2004		(1,567	)		(8,647	)
	$	(32,881	)	$	(86,513	)

(d) To record the net effect of eliminating NeighborCare’s historical tax provision, establishing NeighborCare’s tax provision at the Company’s effective rate based on its historical results presented and to tax effect the net pro forma adjustments at the Company’s effective tax rate.

(e) The following is a pro forma computation of ratio of earnings to fixed charges to present the pro forma effect of the NeighborCare, Inc. acquisition for the noted periods:

Statement of Pro forma Computation of Ratio of Earnings to Fixed Charges:

	Nine Months Ended September 30, 2005			Twelve Months Ended December 31, 2004
Income from Continuing Operations before Income Taxes and Equity Earnings	$	254,749		$	274,672

Fixed Charges	$	148,278		$	197,361
Ratio of Earnings to Fixed Charges (i)		2.7	x		2.4	x
