Autonomy's Hosted eDiscovery Platform Extends Market-Leading Position

Unique Meaning-Based Technology and Unmatched Scalability and Performance Enables Legal Teams to Process More Than Four Million Documents a Month

CAMBRIDGE, England and SAN FRANCISCO, June 15, 2010 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that the
company's hosted eDiscovery platform continues to extend its
market-leadership with several major wins around the world, including Huron
Consulting Group, Skikos, Crawford, Skikos, Joseph & Millican LLP and Womble
Carlyle Sandridge & Rice, PLLC.

With 7,000 servers across seven secure data centers in the U.S. and U.K.,
Autonomy's hosted eDiscovery platform is a fully outsourced offering that
provides data identification, preservation, collection, processing, analysis,
review and production capabilities. The platform is powered by Autonomy's
Intelligent Data Operating Layer (IDOL), which provides advanced search and
analysis capabilities that dramatically improve efficiency in the review and
analysis phase, and increase review speeds by more than 300 percent over
traditional legacy methods. It generates hard dollar return-on-investments in
terms of time and eDiscovery cost savings by more than 50% when compared to
other solutions.

With Autonomy hosted eDiscovery, a customer's data is maintained with a
single vendor on a single platform, which ensures that the chain of custody
remains intact from beginning to end. This dramatically reduces time, cost
and risk of spoliation and loss of data. Autonomy's single platform allows
for comprehensive and detailed reports to track the data at each step of the
process, enabling organizations to demonstrate an auditable and defensible
practice in accordance with the Federal Rules of Civil Procedure (FRCP).
Autonomy's hosted eDiscovery applies advanced technology including conceptual
and contextual analytics, automated clustering and categorization, full
language independence, as well as the ability to analyze audio, video, and
rich-media natively alongside all of the other documents.

"As a long-standing customer of Autonomy, we have seen the benefits of
their hosted eDiscovery platform," said Christopher Getner, managing director
in Huron Consulting Group's Legal Consulting segment. "Huron and Autonomy
share a deep understanding of the unique requirements of the legal technology
market. It is no accident that Huron built its ground-breaking eDiscovery
service offering on the technology and systems of Autonomy. Their continued
innovation is why we recently expanded our commitment in their platform, and
why we view Autonomy as an important long-term partner to Huron and a
long-term partner in driving down the costs of eDiscovery for clients."

Autonomy's meaning-based end-to-end hosted eDiscovery platform consists
of three modules. They include:

    - Autonomy Investigator and Early Case Assessment enables legal
      teams to rapidly pre-review electronically stored information (ESI) and
      assesses the merits of a case using powerful and user-friendly
      analytics. Autonomy Investigator allows legal professionals to
      accurately identify ESI as responsive, non-responsive or privileged,
      and prioritize that data in hours and days, instead of weeks or months.
    - Autonomy Introspect is the world's leading processing, review and
      production platform. Introspect is able to process petabytes of ESI,
      including more than 100 languages and 1,000 file types, and
      intelligently filters and culls the data to quickly reduce volume and
      gain visibility to the information contained within massive data sets.
      The Introspect processing services team carefully manages the critical
      processes of batch tagging and exporting the resulting set of
      documents, de-duplicating and extracting the metadata and preparing
      documents in a litigation-ready format.
    - Autonomy Legal Hold provides the ability to manage notifications
      and to collect data directly to the cloud, a first in the industry to
      allow organizations to intelligently analyze and pre-cull data in-place
      with advanced conceptual search capability and then collect the
      relevant data directly to the cloud. It securely identifies data
      sources, distributes client software, and preserves and collects a
      forensically sound copy of relevant information directly to Autonomy's
      secure cloud-based archive, the Digital Safe.

"Autonomy's end-to-end hosted eDiscovery platform delivers the industry's
most scalable, secure and advanced functionalities to global corporations and
law firms," said Mike Sullivan, CEO of Autonomy ZANTAZ. "By providing one
end-to-end platform that can directly chain together corporate legal
departments and their law firms, Autonomy is revolutionizing how corporate
legal counsels and law firms work together. The Autonomy offering can
dramatically reduce eDiscovery costs and time for corporations, while
ensuring corporate compliance."
