BAD HOMBURG, Germany -- Fresenius Medical Care AG & Co. KGaA (Frankfurt Stock Exchange: FME, FME3) (NYSE: FMS, FMS-p), the world's largest provider of dialysis products and services, today announced that its wholly-owned subsidiary Fresenius Medical Care Holdings, Inc. and Renal Care Group, Inc.

Ben Lipps, Chief Executive Officer of Fresenius Medical Care, commented: "We are very pleased to have reached an agreement with such a qualified and committed buyer at a facility valuation that is comparable to recently announced transactions in the renal industry. We are confident that DSI is as committed as Fresenius Medical Care and Renal Care Group to continuing to provide high-quality care for our patients while we accomplish a smooth and prompt transition that supports our employees and affiliated physicians. We look forward to completing our merger with Renal Care Group, which is targeted to close on or before March 31, 2006, subject to meeting all closing conditions including final approval by the FTC."
