                                 Model

    CommVault Participates in The Sedona Conference(R) RFP+ Vendor
                                 Panel

OCEANPORT, N.J.--(BUSINESS WIRE)--Aug. 26, 2008--CommVault (NASDAQ: CVLT) -

-- eDiscovery will play a significant role in enterprise computing as
 organizations deal with increased litigation and financial risk
 caused by the proliferation of electronically stored information
 (ESI). Furthering its commitment to the advancement of industry
 standards in eDiscovery and archiving, CommVault will participate in
 the Electronic Discovery Reference Model (EDRM), a foundational
 organization created to develop guidelines and standards for
 eDiscovery consumers and providers.
-- The EDRM provides a common, flexible and extensible framework for
 the development, selection, evaluation and use of eDiscovery products
 and services. CommVault joins more than 80 organizations in the EDRM
 that are focused on discovery management, with a particular emphasis
 on technology-based solutions.
-- With a long-standing history of advancing eDiscovery technology and
 many organizations already using the CommVault(R) Simpana(R) 7.0
 Software suite to address the identification, collection,
 preservation (Legal Hold) and analysis of data, customers are assured
 that through CommVault's participation in the EDRM, their evolving
 data and information management needs will be met as the move to
 adopt more stringent processes for storing ESI continues.
 Specifically, CommVault customers can benefit from CommVault's
 efforts to reduce the cost, time and manual work associated with
 eDiscovery.
-- EDRM consists of a series of projects designed to educate
 eDiscovery consumers and providers, enable the integration of
 multiple e-discovery technologies and streamline eDiscovery
 processes. To help drive this awareness, CommVault is participating
 in the following initiatives:
    -- EDRM Evergreen - As part of this initiative, CommVault assists
     in ensuring that the EDRM remains current, practical and relevant
     to the industry as eDiscovery practices evolve. CommVault works
     to deliver solutions that address the various stages of the EDRM
     model while educating end-users on making effective use of the
     model.
    -- EDRM Metrics - This project provides an effective means of
     measuring the time, money and volumes associated with eDiscovery
     activities. As part of the Metrics model group, CommVault is
     helping create tracking, reporting and measurement protocols to
     assess e-discovery activities, and, to the extent metrics data
     becomes available, begin analysis of that data.
    -- EDRM Search - This project provides a framework for defining
     and managing various aspects of Search, as applied to the
     eDiscovery workflow. CommVault will share best practices around
     culling and locating ESI. By specifying the type of search, its
     behavior and expected results, CommVault can address the
     uncertainty and incompleteness sometimes associated with search
     related actions.

CommVault Participates in the RFP+ Vendor Panel of The Sedona Conference(R)

    --  As an extension and further validation of CommVault's
        expertise in the identification, preservation and collection
        of ESI, CommVault has become a member of The Sedona
        Conference(R) RFP+ Vendor Panel, whose goal is to help users
        of eDiscovery vendors develop RFI's and RFP's in a manner that
        allows for more effective communication between user and
        vendor, enhanced ability to compare apples to apples, and
        ultimately, reduced transaction costs and more predictable
        outcomes.

    --  As a member of the RFP+ Vendor Panel, CommVault helps provide
        tools and guidance for end users submitting RFP's for
        eDiscovery solutions. The seamless integration of eDiscovery
        functionality within the CommVault Simpana software suite
        further broadens CommVault's ability to discover all types of
        data with a single unified console. Since its formation in
        2004, The Sedona Conference(R) RFP+ Sub Group has developed
        its Best Practices for the Selection of eDiscovery Vendors and
        The Sedona Conference(R) Glossary (2005 versions and new,
        updated, 2007 versions), both of which have become standards
        in the industry. The RFP+ Vendor Panel as a group also
        consults with The Sedona Conference(R) Working Group on
        Electronic Document Retention and Production on Commentaries
        and Guidelines related to eDiscovery including search and
        retrieval, quality control in the production of ESI, and
        related topics.

        nonprofit, non-partisan, 501(c)(3) law & policy think-tank
