The Metropolitan Water District of Southern California Selects Autonomy for eDiscovery

CAMBRIDGE, England and SAN FRANCISCO, January 26 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that the
Metropolitan Water District of Southern California (the Metropolitan) has
selected Autonomy's end-to-end eDiscovery platform for its Electronic
Discovery Management System. The Autonomy platform includes Legal Hold,
Investigator and Early Case Assessment, Introspect, and Enterprise Archiving
Solution (EAS) and is designed to effectively comply with the U.S. Federal
Rules of Civil Procedure (FRCP) as well as the Public Records Act. The
Metropolitan Water District of Southern California is a consortium of 26
cities and water districts that provides drinking water to nearly 19 million
people in parts of Los Angeles, Orange, San Diego, Riverside, San Bernardino
and Ventura counties.

Autonomy delivers the industry's most comprehensive, modular end-to-end
eDiscovery platform that includes media restoration, consolidated archiving,
legal hold, preservation and collection, early case assessment, advanced
electronic data discovery, review, production, real-time policy management
and analytics functions, all built on a single meaning-based information
access platform - Autonomy's Intelligent Data Operating Layer (IDOL). IDOL
automates the understanding and processing of all sources of information
including email, instant messages, files, applications, voice and video. This
unique end-to-end solution mitigates risk and reduces costs by enabling
customer data to pass seamlessly through the eDiscovery process, without the
need for multiple vendors that could compromise the data or taint the chain
of custody.

"With the increasing government regulations in eDiscovery coupled with
the ever-growing volume of electronically stored information (ESI),
organizations in both the private and public sectors must conduct an in-depth
evaluation of the effectiveness of their information management system," said
Mike Sullivan, CEO of Autonomy ZANTAZ. "Organizations demand an end-to-end
eDiscovery solution that offers ease of use as well as high levels of
scalability, security, speed of processing, and support for foreign languages
and audio."
