NW_20031203_VASCO Data Security International, Inc. and ActivCard, S.A. Reach Settlement Agreement

VASCO Data Security International, Inc.
(Nasdaq: VDSI - News; www.vasco.com ), a global provider of security products that
enable e-business and e-commerce, today announced that the company has settled
its lawsuit with ActivCard, S.A. relating to VASCO's Digipass authentication
products. ActivCard had asserted that VASCO infringed two ActivCard patents,
and that the design of VASCO's Digipass products violated ActivCard's trade
dress, in a federal lawsuit in Delaware. The agreement dismisses the lawsuit,
grants VASCO a worldwide license under the patents and avoids further disputes
between the parties as to the current VASCO product line.
"These agreements will enable us to focus on serving our customers rather than spending our energy on lengthy legal disputes. We look forward to a more positive business environment by which both parties can accelerate the development of their authentication systems," said Ken Hunt, VASCO's Chairman & CEO.

Additional details of the agreement were not disclosed.
