Autonomy's Industry-Leading eDiscovery Technology Now Available on an Easy-to-Use Appliance

Only Autonomy's Meaning-Based eDiscovery Appliance Combines Advanced Early Case Assessment and Legal Hold

CAMBRIDGE, England and SAN FRANCISCO, January 27 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced the availability
of the Autonomy eDiscovery Appliance. The industry's only eDiscovery
appliance that combines early case assessment (ECA) and legal hold
capabilities, the Autonomy eDiscovery Appliance arms General Counsel and law
firm partners with a powerful solution for quickly defining and executing an
eDiscovery strategy. Powered by Autonomy's meaning-based technology, this
highly scalable platform provides an extremely fast and effective on-ramp to
the eDiscovery process.

General Counsel and law firm partners today face immense pressure. With
every legal action, they face scrutiny from either their clients, board of
directors, or government regulators, as well as extremely fast timetables
established by the courts. Failure to quickly craft and execute an effective
strategy for each matter can put the case in jeopardy. Likewise, failure to
meet legal hold obligations will subject the organization to significant
fines and penalties as well as the potential for individual fines, jail time,
and loss of license.

Due to the crushing timetables of the eDiscovery process, the faster
counsel can accurately assess the relevant information for each case, form a
legal strategy, and apply the necessary legal hold, the more likely they will
protect the organization and themselves, ensuring a successful outcome.
However, this has proven to be a huge and expensive challenge for
corporations and law firms alike, as traditional systems are unable to
perform an FRCP-compliant search on the constantly growing and diverse set of
data, and require managing costly, time-consuming, and manual processes.

The Autonomy eDiscovery Appliance automates this process by enabling
counsel to quickly and easily run their data through the appliance, obtain a
comprehensive and precise understanding of their case, and apply legal holds
when appropriate. The appliance is highly scalable, capable of reviewing and
understanding petabytes of information, including all languages and file
types, in a matter of hours. It leverages Autonomy's unique ability to
analyze the data in-place, and perform FRCP-compliant search, automated
clustering, contextual analysis, and audio search.

"Autonomy is reinventing the eDiscovery process to meet the needs and
realities of the modern day market," said Mike Sullivan, CEO of Autonomy
ZANTAZ. "The traditional approach, which depends on antiquated keyword search
technology and an army of technicians, is simply too time-consuming and
costly, and puts businesses at serious risk. Autonomy is bringing the power
of its end-to-end eDiscovery technology to a turnkey appliance, to radically
simplify and accelerate the eDiscovery process for corporations."

The Autonomy eDiscovery Appliance delivers a broad set of unique
capabilities to provide an easy-to-use eDiscovery appliance, including:

    - Unmatched FRCP-complaint search capabilities - unlike legacy
      technologies which are limited to stemming, Autonomy provides true
      meaning-based technology
    - Analyze-in-Place - the only solution that can analyze data
      in-place, prior to collection, from more than 400 enterprise data
      sources
    - Advanced visual analytics - link maps, automatically generated
      concept clusters and message tracers provide legal counsel with a
      bird's-eye view of the data corpus
    - All data types - ability to handle more than 1,000 file types
      natively, including audio and video
    - Petabyte scalability - the Autonomy Discovery appliance is the
      only solution able to handle petabytes of data
    - Extensive reporting and analytics - the only FRCP-compliant and
      defensible solution provides extensive reporting and visibility into
      the process
