Stericycle Receives Clearance to Acquire MedServe

Lake Forest, IL, Nov. 30, 2009 – Stericycle, Inc. (NASDAQ:SRCL), today announced that it has entered into an agreement with the United States Department of Justice and the States of Missouri and Nebraska providing clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 that will allow Stericycle to complete its pending acquisition of MedServe, Inc. Stericycle expects to complete this acquisition during the fourth quarter of 2009, as previously announced.

The agreement requires Stericycle to divest certain assets that it will acquire from MedServe consisting of an autoclave treatment facility in Newton, Kansas, four transfer stations in Kansas, Oklahoma, Nebraska and Missouri and certain large customer accounts and associated assets related to these facilities. In addition, the agreement requires Stericycle for a period of 10 years to notify the United States Department of Justice and the States of Missouri and Nebraska before acquiring any business that is engaged in both the collection and treatment of infectious waste in Kansas, Missouri, Nebraska and Oklahoma.

The agreement with the Department of Justice and the States of Missouri and Nebraska, in which MedServe also joined, is reflected in an order filed today by agreement of the parties in the U.S. District Court for the District of Columbia.

In a related development, Stericycle and MedServe agreed to reduce the merger consideration payable by Stericycle by $2,500,000 from $185,000,000 to $182,500,000, subject to further reduction for MedServe’s indebtedness as of the closing date, MedServe’s expenses in connection with the transaction, and other expenses related to the transaction.
