Zi Corporation to Acquire Assets of Decuma AB of Sweden.

CALGARY, Alberta & LUND, Sweden -- Purchase of Handwriting Recognition Technology to Expand Zi's Suite of User Interface Technologies for Mobile Devices

Zi Corporation (Nasdaq:ZICA)(TSX:ZIC), a leading provider of intelligent interface solutions, announced today that it has signed an agreement to purchase the assets of handwriting recognition software specialists Decuma AB for a purchase price of approximately US$1.0 million, payable in newly issued shares of Zi Corporation common stock. Under the agreement, Zi will purchase all intellectual property and substantially all other assets and trade accounts, the latter subject to price adjustment, of privately-held Decuma.

President and CEO Michael D. Donnell said that the acquisition of Decuma expands Zi's suite of technologies and fits into the Company's strategy of providing a broad range of solutions that improve and enhance the user's experience with wireless handheld devices.

Decuma's handwriting recognition technology creates a new concept for handwritten text input that is modelled closely to actual writing with pen on paper. It is very accurate and designed to make handwritten text input natural and fast. Since users do not have to become skilled at a specific writing style, learn special characters or master a special alphabet, they can focus on the content rather than the writing style.

"Decuma's innovative handwriting recognition technology is definitely complementary to Zi's eZiText(R)," Donnell said. "The combination of Decuma's handwriting recognition and Zi's prediction technology fits our strategy of developing software to simplify and enhance the use of mobile devices. By marrying our prediction technology with Decuma's advanced handwriting recognition, we believe we can further strengthen our competitive advantage and increase market share by offering a more complete suite of well differentiated products. We look forward to assimilating Decuma into our business and working closely with its innovative staff."

The transaction, which is expected to close in early January 2005 following approval by Decuma's shareholders, is subject to Zi's receipt of certain contract assignments and various acknowledgments pertaining to the business operations of Decuma. The issuance of Zi shares is subject to regulatory approvals.

The Swedish company developed its handwriting recognition software based upon its patented Geometrical Invariant Technology (GIT). With solutions for Western languages, Japanese and Chinese, Decuma offers handwriting recognition software to end users as well as manufacturers of handheld devices.

Decuma's product line consists of three handwriting recognition software products: Decuma OnSpot, for English, French, Spanish, German, Italian and other Western languages; Decuma Chinese for Simplified and Traditional Chinese; and Decuma Japanese, which supports Kanji, Hiragana, Katakana, English alphabetic characters and Arabic numbers. The Company products are compatible with the Palm operating system, Windows CE and the Symbian operating system.
