                     VASCO Provides First Quarter Update -
      Expects Operating Income in Q1 2003, Strong First Quarter Revenues,
                    Improved Cash Position and Order Backlog


OAKBROOK TERRACE, Illinois and BRUSSELS, Belgium - April 3, 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 revenues for the
first quarter of 2003 are expected to be in the range of $5.5 million to $5.7
million, compared with $3.6 million for the fourth quarter of 2002. Revenues for
the quarter reflect the impact of VASCO's just-in-time delivery program, which
was introduced in November 2002, and the continued strong order flow during the
first quarter of 2003. VASCO expects to report operating income for the first
quarter of 2003 and expects that order intake will be strong in the second
quarter of 2003.

VASCO indicated that its just-in-time program, which was designed to work with
strategic banking customers to more closely coordinate the delivery of product
to meet their needs, has been successful in giving VASCO more visibility into
the timing of demand for product from strategic customers and has resulted in
lower costs and improved cash flow.

The Company also indicated that it expects its cash position at March 31, 2003
to exceed $3.6 million, an increase of approximately $1.0 million from December
31, 2002, and that the order backlog at March 31, 2003, for firm orders to be
delivered in the second quarter of 2003, was approximately $5.0 million. The
Company noted that the improved cash position was a result of having received
deposits on orders for delivery in 2003 under the just-in-time delivery program
and having reduced days sales outstanding ("DSO") in receivables. These
improvements were partially offset by an increase in total receivables that
resulted from higher revenues in the quarter. The Company further indicated that
all of its credit facilities remained in place, including an unused line of
credit for up to 2 million Euros.

"We are pleased with the results of our first quarter. Our customers understand
the benefits of our just-in-time delivery program and the market, overall, has
continued to show a strong acceptance of our products. As a result, we have been
able to plan more efficiently which has helped us contain costs and improve cash
flows. With revenues at $5.5 million to $5.7 million, and with the actions we
have taken previously to reduce costs, I am confident that we will report
operating income for the first quarter of 2003," stated Jan Valcke, President
and COO. "Going forward, we are committed to managing our business in a
controlled, profitable manner, while still participating in the strong growth of
the IT security sector."

"I am particularly proud of Jan and his team for their efforts which are
expected to result in operating income in the first quarter 2003 and set the
stage for a strong full-year 2003. As I mentioned in my comments on the
full-year 2002 results, we, as a Company, needed to develop a cogent business
plan and execute it. Given the significant restructuring that has taken place in
2001 and 2002, it is gratifying to see the organization, under Jan's leadership,
execute the plan," stated T. Kendall Hunt, Chairman and CEO. "Our current order
backlog further indicates we are well positioned to have a strong second
quarter. As was the case during first quarter of 2003, we are not currently
offering guidance for second quarter. However, with our backlog of firm orders
for delivery in the second quarter of approximately $5.0 million, and with our
breakeven in the range of $5.2 to $5.7 million, we continue to be on track in
terms of achieving our plan for the second quarter. Any new orders received
before quarter's end and shipped during the quarter would be additive to this
number."

VASCO indicated that it expects to release final results for the first quarter
2003 during the fourth week of April 2003. The Company will schedule a
conference call to discuss the results and answer related questions at that
time.
