CommVault Sales Video Recognized in Two Categories: Potential to Accelerate Sales and Explaining Information Management

OCEANPORT, N.J. -- CommVault[R] (NASDAQ: CVLT), today announced that its sales video, "Windows Centric Data Management for the Heterogeneous Enterprise", a video presentation that highlights CommVault's Singular Information Management(TM) approach, was recognized with two bronze Telly Awards. An updated version of the winning video can be viewed at http://www.commvault.com/microsoft/msft_cv_prodoverview.asp. The Telly Awards honor the very best local, regional, and cable television commercials and programs, as well as the finest video and film productions.

The 28th Annual Telly Awards involved over 14,000 entries from across the United States and five continents and were judged by a panel of top advertising and production professionals and past winners. The four-minute joint CommVault-Microsoft video explains the synergies between CommVault's Simpana software suite and Microsoft environments and describes how to simplify data management within the enterprise. The video was honored in two categories including 'The Potential to Accelerate Sales' and 'Explaining Information Management in a Creative Way.'

"The Tellys are awarded based on quality and message delivery - our ability to combine great technology and creative genius was instrumental in securing these awards," said Randy De Meno, chief evangelist and head of the Microsoft partnership for CommVault. "The opportunity to work with the talented professionals at Microsoft and Barrington Communications was truly an honor and taking home two Tellys was extremely gratifying."

Barrington Communications of Los Angeles produced the video with vice president, John Levin, serving as producer and editor. "CommVault has a great product and a terrific corporate culture," said Levin. "By giving us the creative license to capture these aspects of the company in a single piece was a win not only for CommVault, but for Microsoft and the customers of both companies."

"We're proud of this video," said Jeffrey Kratz, senior director of Microsoft's US Partner Group. "It highlights the incredible capabilities of the Windows platform when combined with CommVault solutions."

Carter, a past Emmy and Clio winner, the Telly Awards honor the best work of the most respected production companies, television stations, advertising agencies and corporate video departments in the world.
