Item 1.01

Entry into a Material Definitive Agreement

On May 9, 2009, we and our wholly-owned subsidiary, ATMW Acquisition Corp. (“Merger Sub”), entered into an agreement and plan of merger with MedServe, Inc. a Delaware corporation (“MedServe”), and Avista Capital Partners, L.P., a Delaware limited partnership, as the stockholders’ representative. Pursuant to the merger agreement and upon completion of the merger, Merger Sub will be merged with and into MedServe and MedServe will become a wholly-owned subsidiary of ours.

MedServe is privately held. It is engaged in the collection, transportation, treatment and disposal of medical waste, hazardous waste, universal waste and other regulated wastes, sharps management services, safety and compliance training services, and other related businesses.

The total merger consideration payable by us is $185,000,000 in cash, subject to 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. In addition, $27,750,000 of the merger consideration will be deposited in escrow to cover indemnification obligations of the MedServe stockholders under the merger agreement.

Concurrently with the parties’ execution of the merger agreement, MedServe stockholders holding a majority of its outstanding shares entitled to vote delivered their written consent approving the merger agreement and the merger.

The merger is subject to customary closing conditions and regulatory reviews, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
