VASCO Reaches Agreement With Ubizen N.V. to Redeem Ubizen's USD 15 Million
Investment in VASCO for USD 4 Million in Cash and 2 Million Shares of VASCO
Common Stock

 Agreement with Ubizen is Another Important Milestone in VASCO's Recent Success

OAKBROOK TERRACE, Illinois and BRUSSELS, Belgium - July 17, 2003 - VASCO (Nasdaq
SC: VDSI; www.vasco.com), a global provider of enterprise-wide security products
that support e-business and e-commerce, today announced that it and Ubizen N.V.
had signed a definitive agreement whereby VASCO would purchase and redeem all of
the VASCO Series C Convertible Preferred Stock and Common Stock Purchase
Warrants owned by Ubizen. Under the terms of the Agreement, VASCO will pay
Ubizen USD four (4) million in cash and issue two (2) million shares of VASCO
Common Stock.

Under the terms of the Purchase Agreement, VASCO will pay Ubizen USD three (3)
million and issue two (2) million shares of VASCO Common Stock on or before July
25, 2003. VASCO will pay Ubizen an additional USD one (1) million on or before
November 14, 2003. The Common Stock issued by VASCO will be subject to a lock-up
period wherein the lock-up will expire in increments of 500,000 shares each on
October 15, 2003, January 15, 2004, April 15, 2004, and July 15, 2004. Once the
lock-up expires, the shares will be subject to volume trading restrictions
through January 1, 2005.

The Series C Convertible Preferred Stock along with warrants to purchase
1,269,474 shares of VASCO common stock were originally sold to Ubizen for USD 15
million in July 2000. The Preferred Stock was subject to a mandatory redemption
feature that would have been effective in July 2004. At the mandatory conversion
date, VASCO was obligated to either redeem the Preferred Stock for USD 15
million in cash or issue an equivalent value in VASCO Common Stock at a per
share price that was calculated to be equal to the average trading price of
VASCO's Common Stock for the 30 trading dates prior to the redemption date less
five (5) percent.

"After obtaining a positive cash flow, profitability and the sale of VACMAN
Enterprise, this agreement is another important objective that VASCO's
management team has attained in order to move the company forward." stated T.
Kendall Hunt, Chairman and CEO. "It has become apparent that the market, our
customers, and financing sources were all concerned about the dilution that may
have resulted if the Preferred Stock reached the mandatory conversion date. With
this Agreement in place, VASCO can now work more effectively with all parties.
We are very glad that, after having proven to the market to be a profitable
company by announcing two strong quarters, we were able to reach this agreement
on positive terms. While we still have some work to do to finalize other
financing arrangements, those arrangements will be easier to address with the
issue of the mandatory conversion behind us. "
