Business Editors

TORONTO--(BUSINESS WIRE)--April 18, 2002

DataMirror Corporation (Nasdaq: DMCX)(TSE: DMC) today announced an increase in its offer to acquire all of the outstanding ordinary ("common") shares of Idion Technology Holdings Limited (JSE: IDI), an independent developer of high availability and resiliency software for IBM iSeries, other than those shares already held by DataMirror. DataMirror's original offer of ZAR 65c (Cdn. $0.09) per common share announced on March 18, 2002 valued Idion at approximately Cdn. $9.8 million on a fully diluted basis. DataMirror is now offering a price of ZAR 1.20 (Cdn. $0.17) per common share, which values Idion at approximately Cdn. $19.1 million on a fully diluted basis. DataMirror and a wholly owned subsidiary currently own an aggregate of approximately 16.58% of the outstanding common shares of Idion. The cost of acquiring the remaining common shares would be approximately Cdn. $15.9 million. The original offer was conditional on DataMirror receiving acceptances that would result in it acquiring at least 90% of the common shares of Idion not held by DataMirror. The revised offer will be conditional on DataMirror receiving sufficient acceptances for it to acquire 50% plus one of all common shares of Idion on a fully diluted basis and is subject to certain other conditions, including receipt of all necessary regulatory approvals. The revised offer, made by way of a takeover bid to all holders of common shares of Idion, represents a premium of approximately 38% to the trade weighted average price of Idion common shares on The JSE Securities Exchange, South Africa, during the period from March 18, 2002 to April 17, 2002. DataMirror has sufficient cash on hand to fully fund the offer. DataMirror will mail the revised offer to Idion shareholders on April 19, 2002.
