NW_20010404_en_VASCO Acquires Global Web Security Software Company Identikey Ltd.

OAKBROOK TERRACE, Ill. and BRUSSELS, Belgium -April 4, 2001 - US-based VASCO Data Security International, Inc. (Nasdaq NM and Nasdaq Europe: VDSI; www.vasco.com), a global provider of security solutions that enable e-business and e-commerce, announced that it has acquired control of Identikey Ltd. (www.identikey.com ), a privately held international security software company headquartered in Brisbane, Australia, with operations in the United States, Europe and Australia. The purchase price of approximately $2 million was paid in shares of VASCO Common Stock, with potential additional earnout payments based on defined performance incentives. VASCO expects the acquisition to be neutral to its earnings per share for the 12 months following the acquisition, and significantly accretive after that period.

VASCO has acquired Identikey to increase its market share and revenues in the rapidly growing web security marketplace, to expand its product line for securing web-based applications, and to enhance its ability to deliver market-driven security software products. VASCO plans to announce its first new products from the acquisition of Identikey under its SnareWorks family of products during 2001.

“We were able to close the Identikey acquisition in due course thanks in large part to the longstanding and mutually productive partnership between our two companies,” noted Mario Houthooft, President and CEO of VASCO. “As a result, VASCO is now in a better position than ever to provide web portal and web-based application security to our customers worldwide. We will soon introduce innovative security software, based on the Identikey platform, that will enable any corporation, financial institution, and government agency to secure their e-business and e-commerce initiatives, easily and affordably.”

Mark Kefford, previously CEO of Identikey and now a member of the VASCO management team, concurred. “Our family of web security software products complements VASCO’s expertise in strong authentication and enterprise-wide security, and will allow us to become what we believe will be the security platform of choice for supporting business initiatives, reaching from the mainframe to the web with equal ease.”
