Cognos adjusts public offer for Frango OTTAWA, ON and BURLINGTON, MA, September 21, 2004 - Cognos Incorporated (Nasdaq: COGN; TSX: CSN) today decided to adjust its public tender offer to the shareholders of Frango AB (publ) ("Frango"), announced on August 24, 2004 by reaching an agreement to eliminate the higher bid premium on the Series A shares (held by Tom Löfstedt) relative to the Series B shares (valued at approximately SEK 2.8 million) and increasing the offer to all Frango shareholders by the same amount, or SEK 0.50 per each Series A and Series B share outstanding. The adjustment is a response by both Cognos and Tom Löfstedt to comments expressed by some shareholders regarding the fairness of paying a premium for the Series A shares. The adjustment means that the consideration in the offer is changed as below: * SEK 85.50 in cash per Series A share (previously SEK 93.50 in cash) * SEK 85.50 in cash per Series B share (previously SEK 85.00 in cash) The shareholders Livförsäkringsaktiebolaget Skandia, Nordea Småbolagsfond Norden and Nordea Invest Nordic Small Cap Fund, which combined represent 14.0% of the capital and 8.5% of the votes in Frango have stated that they support the transaction and will accept the adjusted offer provided no higher bid is presented. Including the previously communicated support for the offer, Cognos has now received undertakings and shareholders support for shareholdings representing 69.0% of the outstanding votes and 48.8% of the outstanding capital of Frango. The terms and conditions and the time schedule of the Offer stated in Cognos' press release as of August 24, 2004 as well as in the prospectus dated September 1, 2004 remains unchanged. Shareholders of Series B shares, who have already tendered their shares will receive the higher consideration, SEK 85.50 per share, and are not required to send in any new acceptances to accept the adjusted offer.
