                          Open Text Acquires Corechange

Waterloo, ON--February 26, 2003--Open Text(TM)Corporation (Nasdaq: OTEX, TSX:
OTC) and Corechange, Inc. today announced the closing of the acquisition of all
of the issued and outstanding shares of Corechange by a wholly owned subsidiary
of Open Text.

Corechange's portal software provides a comprehensive window into a company's
enterprise content, applications, services, and productivity tools. Coreport,

deploying secure, scalable intranet and extranet portals. Benefits of
integration with Open Text's Livelink(R), the leading collaboration and
knowledge management system, include:

     o    Enhancement of Livelink connectors UNITE and Doorways.

     o    Application integration at the point of access. With Corechange's
          portal framework, Livelink will offer a horizontal solution unifying
          existing applications in CRM, ERP and SCM.

     o    Direct interaction with any kind of application running on any
          platform both web and legacy -- with no change to the native
          application and no loss of functionality.

"The Coreport portal framework includes a unique set of built-in features that
make it easy to collaborate effectively with colleagues, customers and
partners," said Tom Jenkins, Chief Executive Officer of Open Text. " By
combining this portal framework with the Livelink product family, we create
integration at the point of access extending the functionality of leading
business applications."

"Joining Open Text, an established global software leader, helps us better meet
the support and service needs of our Fortune 1000 customers," said Charles F.
Kane, Chief Executive Officer of Corechange. "Corechange customers will benefit
from the integration of Open Text's collaboration, knowledge management and
content management technologies into Coreport."

change in guidance for Open Text's fiscal 2003 year. For further information,
please consult Open Text's Current Report on Form 8-K filed with the U.S.
