DataMirror Corporation - Minor Clarification of Timing of Idion Takeover Offer.

Business Editors/High-Tech Writers

TORONTO--(BUSINESS WIRE)--March 25, 2002

On March 18, 2002, DataMirror Corporation (Nasdaq: DMCX; TSE: DMC) issued a press release related to its cash offer for Idion Technology Holdings Limited ("Idion") that had been announced in Johannesburg, South Africa earlier that day.

There were certain statements in that press release that DataMirror wishes to amend. In the release it was stated that a letter of offer was delivered to the Chief Executive of Idion on Saturday March 16, 2002 in which it was proposed that DataMirror acquires Idion by way of a takeover pursuant to which all holders of common shares of Idion would receive cash proceeds of ZAR 65c (Cdn $0,09) per share, and that such proposal was rejected by Idion management. Although a meeting did take place with the Chief Executive of Idion and DataMirror on that date no formal offer was submitted and accordingly none was rejected by Idion management. The offer letter was only delivered to Idion's directors on Monday March 18, 2002. The error arose due to an administrative oversight at DataMirror.
