AmerisourceBergen Signs Agreement with DEA Leading to Reinstatement of Its Orlando Distribution Center's Suspended License to Distribute Controlled Substances.

VALLEY FORGE, Pa. -- AmerisourceBergen Corporation (NYSE:ABC) today signed an agreement with the U.S. Drug Enforcement Administration (DEA) which is expected to lead to the reinstatement of its Orlando Distribution Center's suspended license to distribute controlled substances on August 25, 2007 at 12:01 a.m. EDT. The reinstatement would allow the Distribution Center to resume shipment of controlled substances to its retail customers at that time.

The agreement requires the Company to implement an enhanced and more sophisticated order monitoring program in all AmerisourceBergen Drug Corporation distribution centers by June 30, 2007, after which the Company must pass several DEA inspections of the new program for the reinstatement to become effective on the August date. The Company expects the new order monitoring program to quickly become the industry standard.

The Orlando facility's license to distribute controlled substances was suspended April 24, 2007, because DEA alleged that the Orlando Distribution Center had not maintained effective controls against diversion of controlled substances, specifically hydrocodone, by retail internet pharmacies. The Orlando facility was given special dispensation to continue to distribute controlled substances to hospitals, clinics and U.S. Department of Defense facilities. As a result, the suspension affects the facility's retail customers, who during the suspension are provided controlled substances by the Company's distribution center in Columbus, Ohio.

The new order monitoring program requires more rapid identification and daily reporting of orders that may indicate diversion of controlled substances, including in some instances, halting the shipment of orders that require further investigation by the Company. The program also requires a more rigorous examination process before the delivery of controlled substances to newly signed customers.
