           OPEN TEXT AND CENTRINITY ANNOUNCE COMPLETION OF ACQUISITION

Toronto, ON--Nov. 1, 2002--Open Text(TM)Corporation (Nasdaq: OTEX, TSX: OTC),
provider of Livelink(R), the leading collaboration and knowledge management
software for the global enterprise, and Centrinity Inc. (TSX: CTI) today
announced the acquisition of all of the issued and outstanding shares of
Centrinity for cash consideration of CDN $1.26 per share has been completed. The
transaction was completed by way of an amalgamation of Centrinity with 3801853
Canada Inc., a wholly-owned subsidiary of Open Text. Shareholders of Centrinity
approved the amalgamation at a meeting of shareholders held earlier today.

Centrinity has more than 8 million users of its FirstClass(R) Communications
Platform, which is a cost-effective, highly scalable messaging and collaboration
solution designed for business, government, educational institutions and service
providers. FirstClass provides a unified mailbox that brings together a user's
e-mail, voicemail and fax messages. Users, whether mobile or in the office, can
access their mailbox from the device of their choice --a cell phone, telephone,
computer or handheld device.

First Class customers will benefit from an enriched product enhancement path as
technologies from OT are integrated into FirstClass. Centrinity's technology and
expertise will enable Livelink(R) customers to integrate the previously
disparate worlds of e-mail, voicemail and other unstructured content, and
provide organizations with the ability to apply retention rules and compliance
policies to the entire collection of corporate knowledge. Open Text has designed
Livelink to capture information generated through online collaboration and
preserve it in a company's knowledge base.

Technology from the two companies will accelerate the integration between voice
and data conferencing capabilities in Livelink MeetingZone(TM).

Centrinity is based in Richmond Hill, Ontario, and has offices in the United
Kingdom, Ireland and Sweden.
