Onex Announces Completion of Cash Tender Offer

For the Outstanding Shares in ResCare

Toronto, November 16, 2010 - Onex Corporation (together with affiliates, “Onex”) (TSX: OCX) today announced that Onex Rescare Acquisition, LLC, an affiliate of Onex Partners III LP, has successfully completed its previously-announced cash tender offer for all of the outstanding shares of common stock of Res-Care, Inc. (Nasdaq: RSCR) not owned by Onex or its affiliates. The tender offer expired at 5:00 P.M., New York City time, on November 15, 2010.

Based on information provided by Computershare Trust Company, N.A., the depositary for the tender offer, a total of 20,678,039 shares of common stock, representing approximately 81.6% of the outstanding shares of common stock not owned by Onex, its affiliates or certain members of ResCare’s management who have agreed to “roll-over” their current equity ownership position, were validly tendered and not withdrawn in the offer, together with an additional 548,707 shares tendered by guaranteed delivery. All shares that were validly tendered and not withdrawn have been accepted for payment. Onex does not intend to offer a subsequent offering period in connection with the offer. As a result of the successful completion of the tender offer, Onex and its affiliates hold an 85.3% interest in ResCare, on an as-converted basis (excluding shares tendered via guaranteed delivery).

As contemplated by the terms of the previously-announced share exchange agreement between Onex and ResCare, Onex intends to acquire the remaining publicly-held shares of ResCare’s common stock in a second-step share exchange transaction under Kentucky law in which each outstanding share of ResCare common stock that was not acquired by Onex in the offer will be exchanged for $13.25 in cash. The second-step share exchange will be completed following approval of the share exchange at a meeting of ResCare shareholders to be held as soon as practicable. As a result of the purchase of shares in the tender offer, Onex has sufficient voting power to approve the share exchange at such meeting without regard to the vote of any other ResCare shareholder.
