Xircom Purchases Rex® Product Line from Franklin Electronic Publishers

Wednesday 29 September 1999
Future Rex Version to Incorporate RSA SecurID®
Technology for the Enterprise Market

Xircom UK Ltd, (Nasdaq: XIRC), the leading provider of mobile access solutions for PC users
worldwide, today announced the company’s purchase of the Rex product line from Franklin
Electronic Publishers (NYSE: FEP).

Expanding its wide range of mobile information access solutions, Xircom plans to design
future versions of the Rex product for the enterprise market by incorporating new
applications including security capabilities, web clipping and wireless connectivity.

Under the terms of the agreement, Xircom will pay $13.25 million for selected assets of the
Rex product line, including intellectual property, inventory and fixed assets. This
transaction will be accounted for as a purchase and Xircom expects to incur a charge to
earnings related to the write-off of purchased in-process research and development of
approximately $3 to $4 million for the quarter ended September 30, 1999. The company expects
the transaction to be accretive to earnings within the first year of operations. The
purchase has been approved by the board of directors of each company.

"The Rex solution is an innovative wearable information accessory that is focused on doing
one thing well: making personal data readily available in a size that is truly an
‘unconscious’ carry," said Dirk Gates, chairman, president and CEO of Xircom. "The Rex fits
well as one of Xircom’s mobile information access solutions. Going forward we will continue
to expand the Rex capabilities through industry partnerships with the goal of enhancing
individual and corporate productivity by enabling mobility."

Leveraging the Investment for Future Expansion. Xircom plans to leverage its acquisition of
the Rex product line to create tailored solutions for the enterprise and build industry
partnerships to enhance the product’s functionality.

Through a relationship with RSA Security, Inc. (Nasdaq: RSAS), a leading provider of Internet
security solutions for e-business worldwide, Xircom plans to introduce an enterprise version
of the Xircom® Rex® that combines the current information management capabilities with RSA
SecurID technology to offer two-factor, user authentication for corporate networks.

"As a large RSA Security customer, one of our challenges is that many of our employees carry
multiple computing devices to address all of the functionality that they need," said Rod
McGeary, vice chairman, KPMG Consulting. "Combining Rex personal information management
functionality with the RSA SecurID authentication technology means we have to carry one less
gadget. This solution will help us increase our network security and realise further value
for our mobile technology investments."

Xircom Wearable Information Accessories. Xircom will position Rex as the leading "wearable
information accessory", offering users compact products and personalised applications that
deliver focused functionality. The Rex product line will retain its well-established brand
name under the Xircom umbrella. Xircom Rex solutions are currently available through leading
retail channels.

"As the designer and developer of the TrueSync(TM) Technology platform for the Rex, we look
forward to partnering with Xircom to create future generations of the Rex product line," said
Philippe Kahn, CEO and chairman, Starfish Software, wholly-owned subsidiary of Motorola
(NYSE: MOT). "Xircom is perfectly positioned to maximise the potential of the Rex solution
and ensure that Starfish and Xircom’s joint vision of the Rex product line is fully
realised."
