Autonomy to Automate Aggregation and Delivery of Content to Power Multiple Consumer Portals

London - February 28, 2002 - Autonomy Corporation plc (Nasdaq: AUTN; LSE: AU, Nasdaq Europe: AUTN), a global leader in infrastructure software for the enterprise, has been selected by Hutchison 3G UK Limited ('Hutchison 3G'), holder of the UK's largest 3G licence to provide a intelligent content retrieval solution. Initially the system will be deployed in the UK and later made available in other countries where Hutchison Whampoa has 3G interests.

Autonomy's Intelligent Data Operating Layer (IDOL) and interface Portal-in-a-box, will enable Hutchison to classify and deliver unique, location-specific information from hundreds of sources, including live news, e-commerce, sport and entertainment, such as music-on-demand. The software will improve the consumer experience, ensuring that searches and navigations present the most accurate information at the right time, through the right channels and in the most user-friendly format.

Employing Autonomy's technology, Hutchison 3G will minimise traditional labour and maintenance overheads associated with information processing to provide consumers with a single entry point from their mobile and handheld devices to its robust, vibrant network. Initial deployments will occur in the United Kingdom and Italy, with future rollouts scheduled for Austria, Sweden, Hong Kong and Australia.

According to Colin Tucker, Managing Director, Hutchison 3G, Autonomy's infrastructure software was selected because of its unique ability to integrate unstructured, semi-structured and structured information in multiple languages and formats: "As the amount and type of data supported by the 3G network increases, we needed a scaleable solution," said Tucker.

"Due to the display and bandwidth requirements of mobile phones and handheld devices, Hutchison 3G needed a solution that could deliver highly relevant information in real-time to their subscribers," said Dr. Mike Lynch, CEO and co-founder of Autonomy. "Autonomy will provide a scaleable infrastructure that automatically links related information as it becomes available."

"Hutchison 3G is pioneering the next generation of mobile communications," commented Lynch. "Autonomy is pleased to support this revolutionary network."
