CommVault and Clearwell to Deliver Complementary E-Discovery Capabilities

September 5, 2007

Combined Solutions Automate Discovery and Analysis Across All Electronically Stored Information

OCEANPORT, N.J. & SANTA CLARA, Calif., Sep 05, 2007 (BUSINESS WIRE) --

CommVault(R) (NASDAQ: CVLT) and Clearwell Systems, Inc., a leader in Intelligent E-Discovery, today announced that they are teaming up to jointly market the value proposition of the two companies' solutions for e-discovery, risk mitigation and compliance. CommVault and Clearwell will work together to deliver end-to-end e-discovery solutions to enterprise IT and legal departments utilizing the CommVault Simpana(TM) software suite and the Clearwell Intelligence Platform(R).

The newest version of CommVault Archive, one of five core modules that comprise the CommVault Simpana software suite, is a comprehensive archive solution for managing and retaining all electronically stored information (ESI) including email, collaboration, file and Network Attached Storage (NAS) data across online file systems, nearline archives and offline backup tapes from a single user interface. The Clearwell Intelligence Platform augments CommVault's already robust messaging and file archiving, classification, records preservation management and search capabilities with market-leading analysis and review. The combined solution can deliver significant cost savings by streamlining and automating archiving, discovery and analysis across the entire storage environment as part of a singular approach to data and information management.

"Having access to all electronically stored information and not just email is critical to the successful outcome of any e-discovery response," said Mike Ivanov, senior director and head of CommVault's Archive Center of Excellence. "By working with Clearwell, we are enabling customers to fully unlock the potential of their corporate data. Our combined efforts acknowledge and promote this marriage of critical enterprise content with intelligence and e-discovery software, giving customers an end-to-end solution that reduces the cost, duration and risk of e-discovery."

The relationship includes a comprehensive go-to-market (GTM) plan between CommVault and Clearwell. The relationship also incorporates many facets of joint marketing, including communications, lead generation and sales enablement.

"By significantly reducing the risk, cost and time traditionally associated with e-discovery, our customers become the true beneficiaries of this collaboration," said Kamal Shah, vice president of marketing and product management at Clearwell Systems, which was recently ranked by corporate end users as a top "E-Discovery Software Provider" in the influential Socha-Gelbmann 2007 Electronic Discovery Survey. "The complementary nature of the Clearwell and CommVault solutions highlights how our technology can transform ESI including email data, preserved for compliance purposes, to intelligent information that can be easily and proactively analyzed within a flexible analytical store."

In the U.S. court system, the onus of e-discovery took on new weight on Dec. 1, 2006, when amendments to the Federal Rules of Civil Procedure (FRCP) took effect. A recent survey shows that, on average, U.S. companies face 305(1) lawsuits at any one time translating into millions of dollars in litigation costs. With each lawsuit comes the obligation for discovery - production of evidence for presentation to the other side in a legal dispute. According to research firm Gartner, spending on e-discovery software technologies is forecast to grow at more than 30 percent annually through 2010(2). Gartner currently estimates the worldwide e-discovery total software revenue to grow from $183.9M in 2005 to $847.2M in 2010.(3)
