NOTE 11: LEGAL PROCEEDINGS

On June 28, 2012, Overland Storage, Inc. (“Overland”) filed a patent infringement lawsuit against Quantum and Venture Corporation Limited in the U.S. District Court in the Southern District of California, alleging that certain automated tape libraries of the defendants fall within the scope of patents 6,328,766 and 6,353,581. Overland is seeking injunctive relief, as well as the recovery of unspecified monetary damages, including treble damages for willful infringement. We are well-positioned to defend ourselves and will do so vigorously. Due to the inherent uncertainty of litigation, we cannot identify probable or estimable damages related to the lawsuit at this time.

On September 12, 2011, Compression Technology Solutions LLC (“CTS”) filed a patent infringement lawsuit against a group of companies, consisting of Quantum, CA., Inc., EMC Corporation, Hewlett-Packard Company, International Business Machines Corp., NetApp, Inc. and Quest Software, Inc., in the U.S. District Court in the Eastern District of Missouri, alleging that certain unspecified products of the defendants, characterized as “deduplication software systems,” and, in the case of Quantum, including Quantum’s “DXi Series Deduplication software,” fall within the scope of patent 5,414,650. CTS is seeking injunctive relief, as well as the recovery of monetary damages, including treble damages for willful infringement. We do not believe we infringe the CTS patent; we believe that the CTS patent is invalid, and we intend to defend ourselves vigorously. In April 2012, our motion to transfer venue was granted and the lawsuit was transferred to the U.S. District Court in the Northern District of California. Due to the inherent uncertainty of litigation, we cannot identify probable or estimable damages related to the lawsuit at this time.
