Bank of Brazil Selects Autonomy's Meaning Based Computing Platform

Autonomy IDOL Increases Productivity and Enables Superior Customer Service

CAMBRIDGE, England and SAN FRANCISCO, June 28, 2010 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that the Bank of
Brazil (Banco do Brasil S.A.) is using Autonomy's Meaning Based Computing
platform, IDOL, as part of a strategic initiative to provide employees with
faster access to the company's abundant data sources. Autonomy's Intelligent
Data Operating Layer (IDOL), which indexes multiple sources of data
distributed throughout the bank's global locations, increases productivity
and improves customer service by accelerating internal processes.

Bank of Brazil, founded in 1808, is the largest financial institution in
Brazil and one of the oldest banks in the world. The Bank is a leader in many
areas including mobile banking services, assets, export exchange, asset
management and total deposits. Serving all segments of the financial market
with millions of clients in more than 3,000 cities in multiple countries,
Bank of Brazil strives to ensure that its hundreds of thousands of employees
are equipped with the best technology to maximize productivity.

Prior to Autonomy, it could be a daunting task for a bank employee to be
able to find the right document in a matter of moments to serve a customer.
Bank of Brazil found that Autonomy's IDOL Search Platform - which
intelligently understands concepts in context - could reduce the time spent
looking for information and boost user productivity. By uniquely
understanding the value and meaning within documents, IDOL can more quickly
and intelligently pull together the correct items a user is searching for.
The reduction in time spent searching for accurate information allows
employees to be more efficient and provide customers with faster and superior
service.

Autonomy IDOL performs conceptual and contextual analysis and probability
matching on information to find the meaning within and the
inter-relationships between disparate pieces of content. This unique approach
allows employees at global organizations to find and access the most
pertinent content, irrespective of languages, operating systems, and file
types. By supporting more than 1,000 different data formats, including
structured, semi-structured, and unstructured data, across 400 different
content repositories, Autonomy can search all categories of information in an
organization. IDOL is fault-tolerant using load balancing and mirroring,
highly scalable, secure, and has sub-second performance on billions of files.

"Bank of Brazil is a fast-growing and highly regarded financial
institution," said Mike Lynch, CEO of Autonomy. "They understand the
difference innovative and superior technology makes when supporting such a
large and complex organization as theirs, with hundreds of thousands of
employees and millions of clients. The Bank of Brazil is a perfect example of
the power of Meaning Based Computing at work, where IDOL's scale, speed, and
unique understanding of all forms of data enable the bank to operate
efficiently and continue to deliver superior customer service."
