July 20, 2000

LEUVEN, Belgium, and OAKBROOK TERRACE, Illinois - July 20, 2000 - Ubizen (EASDAQ: UBIZ; www.ubizen.com), a leading provider of total e-security solutions, and VASCO Data Security International, Inc. (NASDAQ: VDSI; EASDAQ: VDSI; www.vasco.com), a leading e-security product company, today announced the formation of a worldwide strategic partnership. The partnership - which is supported by Ubizen investing $15 million in VASCO - takes effect immediately, with both companies signing a mutual preferred provider and supplier agreement. In addition, Ubizen and VASCO will combine sales and marketing efforts to both prospective and existing customers, which include many of the world's leading banks and corporations, as well as government agencies spanning the US, Europe, and Asia/Pacific.

Benefits of the partnership include:

Ubizen obtains preferred access to VASCO's client base with high-end customers requiring total e-security solutions. VASCO will position Ubizen's MultiSecure product line - together with its enterprise security infrastructure software, SnareWorks - to its worldwide base of more than 140 leading financial institutions. SnareWorks is complementary to Ubizen's MultiSecure ETS product, one of Ubizen's security middleware products that provide extensive secure online banking and trading solutions.

VASCO obtains preferred access to a worldwide organization numbering more than 450 e-security professionals, including almost 80 in the US alone. This access will help VASCO accelerate implementation of its enterprise security infrastructure software, SnareWorks, in the US and Europe.

Both companies will promote its combined product and services offering to existing and prospective customers. Ubizen will introduce VASCO's SnareWorks, as well as VASCO's Digipass strong authentication products, to its blue-chip US and European customer base. In addition, the companies will explore joint security solutions that leverage their complementary technologies and support their market-driven product sets.

According to Wouter Joosen, Ubizen's Chief Technology Officer, "the MultiSecure product family - Ubizen's application security middleware - interoperates with best-of-breed infrastructure security products. The Single Sign-On capabilities of SnareWorks complement our MultiSecure ETS middleware product, which is open for authentication technologies, while guaranteeing effective authorization and non-repudiation at the application level."

Both organizations hailed the agreement as an additional step in their international growth as security infrastructure, application, and professional services companies. "Security is a vital component in every e-business environment," noted Ubizen CEO Stijn Bijnens. "Combining VASCO's extensive experience in authentication and access control with Ubizen's expertise in application security middleware provides us with a powerful positioning in a rapidly growing market."

Mario Houthooft, President and CEO of VASCO, concurred. "Our close partnership with Ubizen will allow us to accelerate the execution of our worldwide growth strategy, and we view Ubizen's financial participation in VASCO as an endorsement of our outstanding people, products, and markets. We feel confident that this partnership will bring wide-ranging benefits to our companies and customers today, and in the future."

At any time, the preferred stock will be convertible into shares of VASCO common stock at $14.25 per share, at which time a total of 150,000 preferred shares will be converted into 1,052,632 common shares.
