CAMBRIDGE, England and SAN FRANCISCO, March 3, 2010 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced significant
enhancements to the company's flagship line of web content management (WCM)
platform. Powered by Autonomy's Intelligent Data Operating Layer (IDOL),
Autonomy Interwoven TeamSite, LiveSite, and Virage MediaBin include new
capabilities designed to enable a modern, next-generation web experience. To
date, hundreds of customers worldwide - including American Medical
Association, Arkema, BNP Paribas, Fidelity International, and Loma Linda
University Medical Center - are leveraging the new release of TeamSite,
LiveSite, and Virage MediaBin to deliver an intelligent and engaging global
web presence.

"Autonomy Interwoven's web content management platform plays a vital role
in allowing us to provide a contextually rich and engaging customer
experience," said Nick Abruzzo, Vice President of Interactive Marketing at
American Medical Association. "We are leveraging Autonomy Interwoven's WCM
solution and IDOL site search engine to create a world-class web presence.
The web solution was chosen by IT and marketing because of its ability to

Autonomy Interwoven - the Platform for the Modern Web

Autonomy Interwoven's web content management platform contains all the
elements required to deliver a modern, next-generation web experience,
including new capabilities to support global deployments, leverage rich
media, and deliver highly targeted and optimized content. The new platform
includes the following innovations:

    Rapidly Rollout a Global Web Presence

    - Global Web Presence - the new version of TeamSite provides dependency
      management, automatic language detection, and clustering of
      conceptually related content. This means new content will always be
      accurately and consistently represented in each region.
    - Allow Marketers to Create Websites Faster - the new WCM platform
      provides marketers with new surf-and-edit capabilities like keyword
      shortcuts, fixed area layout and in-line editing for unsurpassed
      usability. Additionally, the platform provides seamless integration
      with Microsoft Office, such as Outlook for task-based approval and
      alerts.
    - Streamlined Installation - the platform also provides streamlined
      installation and administration capabilities through a consolidated
      administration console.

    Automatically Deliver Targeted, Dynamic Content to Any Channel

    - Agnostic Dynamic Content Delivery - LiveSite delivers
      industry-first agnostic content delivery capabilities which allow
      marketers to dynamically display content to any display environment,
      including portal, Flash, AJAX, and .NET. This is a huge benefit to
      today's global organizations, which manage distributed IT environments,
      and struggle to deliver relevant, dynamic content to portals, ecommerce
      sites, and mobile applications.
    - Dynamic Targeting - the platform provides the full spectrum of
      implicit and explicit targeting capabilities across all channels,
      including web, contact center, and social media. Unlike other marketing
      technologies, Autonomy automatically tags and forms a conceptual
      understanding of all content, inside and outside a corporation. This
      underlying capability allows businesses to instantly deliver more
      relevant, targeted content to customers.
    - Integrated Ecommerce - the WCM platform provides out-of-the box
      capabilities for intelligent recommendations, directed navigation,
      merchandising, and advanced search marketing.
    - Integrated WCM and Optimization - Autonomy Interwoven is the only
      platform that combines WCM and Multivariate Testing in a single
      interface. Announced in Q2 of 2009, this combination allows marketers
      to quickly make adjustments that lead to proven increases in online
      conversions.

    Create a Visually Stunning Web Presence

    - Intelligent Use of Rich Media Content - the platform
      leverages Autonomy Virage MediaBin rich media analytics to obtain a
      conceptual understanding of all images or videos, regardless of format
      or language. The system automatically tags all content and presents
      digital assets through a new rich media interface, allowing marketers
      and agency partners to more quickly and easily find and present the
      right image, every time.
    - Ease-of-Use Enhancements - Virage MediaBin also includes a new
      lightweight, browser-based graphics file editor that allows marketers
      to edit, resize, crop, and adjust brightness and color of logos and
      other images directly on a web page.

    Benefit from a Powerful, Meaning-Based Architecture

    - Autonomy Interwoven is the industry's only marketing platform
      that combines a meaning-based architecture - based on IDOL - with
      world-class web content solutions. As a result, Autonomy Interwoven is
      uniquely positioned to deliver a comprehensive marketing platform that
      enables businesses to automatically gain insight on all forms of
      information, act on new opportunities as they emerge, and continually
      optimize these interactions to maximize results.
    - With IDOL as the underlying architecture, customers benefit from
      world-class reliability, scalability, and high-performance, capable of
      evolving as their IT environment and overall web presence becomes more
      complex.

"As the global economy shifts towards an upturn, marketers have a
tremendous opportunity to deepen customer engagement to drive their
business," said Rafiq Mohammadi, CEO of Autonomy Interwoven. "Autonomy
Interwoven is the only company that provides a platform to allow businesses
to truly understand their customers, act on these insights, and continually
