Business Editors/High-Tech Writers

WATERLOO, Ontario--(BUSINESS WIRE)--Jan. 13, 2004

Over 42% of IXOS Shares Tendered, Changes Will

Facilitate Tender Process

Open Text(TM) Corporation (Nasdaq: OTEX, TSX: OTC) advised today that its wholly-owned subsidiary, 2016091 Ontario Inc., has waived the condition of the Offer requiring that at least 67% of the outstanding shares of IXOS Software AG (Nasdaq: XOSY, Frankfurt: XOS) be tendered to the Offer. The acceptance period of the Offer is extended until 12:00 noon (local time Frankfurt/Main, Germany) on Friday, January 30, 2004.

IXOS' Management and Supervisory Boards have indicated that they will confirm their recommendation to IXOS shareholders to accept the Offer as amended.

As at January 13, 2004, in excess of 42% of the outstanding shares of IXOS have been tendered to the Offer. Approximately 24% of these shares have been tendered for the cash consideration offered, and 76% have been tendered for the alternative share and warrant consideration offered. The tenders received to date include the shares held by IXOS' significant shareholders General Atlantic Partners and its affiliates, and founding families Strack-Zimmermann and Faerber. Including IXOS shares purchased in the open market outside the Offer, 2016091 Ontario Inc. now holds or is entitled to acquire under the Offer an aggregate of approximately 43% of the outstanding share capital of IXOS.

"After receiving feedback from the customer base of both companies, we continue to be very excited about the potential of the business combination between IXOS and Open Text," said Tom Jenkins, CEO of Open Text. "Since Open Text announced a better than expected fiscal second quarter (ended Dec 31, 2003), we feel it is prudent to amend the offer which will provide two additional weeks for IXOS shareholders to decide how they will tender. We have added an additional period to settle the tender after the January 30th expiry so that no one will be penalized by this change and those tendering by January 30th will have their IXOS shares settled in the same timeframe as if this change had not been made."

Payment for the IXOS shares tendered to the Offer by the expiry of the acceptance period on January 30, 2004 will commence immediately thereafter and will be completed by approximately February 10, 2004 in the case of the cash consideration and February 20, 2004 in the case of the alternative share and warrant consideration. Following the acceptance period, a mandatory extended acceptance period required under German law will be available from February 6, 2004 to February 19, 2004 to IXOS shareholders that have not accepted the Offer prior to the expiry of the Offer acceptance period on January 30, 2004. Those IXOS shareholders accepting the Offer during the mandatory extended acceptance period will not receive payment for their IXOS shares until approximately March 2, 2004 in the case of the cash consideration and March 12, 2004 in the case of the alternative share and warrant consideration.

All information relating to the amendment of the Offer is contained in the offer amendment document published on the Internet at: www.2016091ontario.de and is available free of charge from Commerzbank Aktiengesellschaft, ZGS-CMAD, DLZ 2, Mainzer Landstrasse 153, 60327 Frankfurt am Main, Germany, fax no.
