Forward-Looking Statements

Information set forth herein contains forward-looking statements, which involve a number of risks and uncertainties. Kindred and RehabCare caution readers that any forward-looking information is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking information. Such forward-looking statements include, but are not limited to, statements about the benefits of the business combination transaction involving Kindred and RehabCare, including future financial and operating results, the combined company’s plans, objectives, expectations and intentions and other statements that are not historical facts.

The following factors, among others, could cause actual results to differ from those set forth in the forward-looking statements: (a) the receipt of all required licensure and regulatory approvals and the satisfaction of the closing conditions to the acquisition of RehabCare by Kindred, including approval of the pending transaction by the shareholders of the respective companies, and Kindred’s ability to complete the required financing as contemplated by the financing commitment; (b) Kindred’s ability to integrate the operations of the acquired hospitals and rehabilitation services operations and realize the anticipated revenues, economies of scale, cost synergies and productivity gains in connection with the RehabCare acquisition and any other acquisitions that may be undertaken during 2011, as and when planned, including the potential for unanticipated issues, expenses and liabilities associated with those acquisitions and the risk that RehabCare fails to meet its expected financial and operating targets; (c) the potential for diversion of management time and resources in seeking to complete the RehabCare acquisition and integrate its operations; (d) the potential failure to retain key employees of RehabCare; (e) the impact of Kindred’s significantly increased levels of indebtedness as a result of the RehabCare acquisition on Kindred’s funding costs, operating flexibility and ability to fund ongoing operations with additional borrowings, particularly in light of ongoing volatility in the credit and capital markets; (f) the potential for dilution to Kindred’s stockholders as a result of the RehabCare acquisition; and (g) the ability of Kindred to operate pursuant to the terms of its debt obligations, including Kindred’s obligations under financings undertaken to complete the RehabCare acquisition, and the ability of Kindred to operate pursuant to its master lease agreements with Ventas, Inc. (NYSE:VTR). Additional factors that may affect future results are contained in Kindred’s and RehabCare’s filings with the SEC, which are available at the SEC’s web site at www.sec.gov.
