FINANCIAL INFORMATION RELATING TO FOREIGN AND DOMESTIC OPERATIONS AND EXPORT
SALES

See Note 10 to VASCO Notes to Consolidated Financial Statements for certain
information about foreign and domestic operations and export sales.

NARRATIVE DESCRIPTION OF THE BUSINESS

GENERAL

We design, develop, market and support security products and services which
manage and secure access to computer systems of corporate and government
customers. Additionally, we enable secure financial transactions made over
private enterprise networks and public networks, such as the Internet. We
believe that our software and hardware products provide organizations with
strong, flexible and effective Internet and enterprise security solutions and
they compete favorably against those of our competitors. Our IdentiSoft division
primarily designs and markets products under the Digipass brand. Our Digipass
product line provides greater flexibility and a more affordable means than
competing products of authenticating to any network, including the Internet. The
Digipass family of user authentication devices, all of which incorporate an
electronic digital signature capability to guarantee the integrity of electronic
transactions and data transmissions, are commonly referred to as security
tokens. Our IntelliSoft division is responsible for open standards-based
software products, including our SnareWorks and VACMAN product lines which
provide enterprise-wide solutions to secure Internet, client/server and
mainframe applications.

Our security solutions are sold worldwide through our direct sales force, as
well as through distributors, resellers and systems integrators. We currently
have approximately 450 customers in more than 47 countries. Representative
customers of our products include: ABN AMRO Bank, University of Gronigen,
HondaEurope, SNS Bank, Rabobank Nederland, SE Banken, Telindus and Pekao
Informatyka.

INDUSTRY BACKGROUND

The growth in electronic banking and electronic commerce, and the increasing
use and reliance upon proprietary or confidential information by businesses,
government and educational institutions that is remotely accessible by many
users, has made information security a paramount concern. We believe that
enterprises are seeking solutions which will continue to allow them to expand
access to data and financial assets while maintaining network security.
According to Datamonitor, the global market for security products is expected to
grow from $2.3 billion in 1998 to over $8 billion in 2003, a compound annual
growth rate of 28%.

INTERNET AND ENTERPRISE SECURITY. With the advent of personal computers and
distributed information systems in the form of wide area networks, intranets,
local area networks and the Internet, as well as other direct electronic links,
many organizations have implemented applications to enable their work force and
third parties, including vendors, suppliers and customers, to access and
exchange data and perform electronic transactions. As a result of the increased
number of users having direct and remote access to such enterprise applications,
data and financial assets have become increasingly vulnerable to unauthorized
access and misuse.

INDIVIDUAL USER SECURITY. In addition to the need for enterprise-wide
security, the proliferation of personal computers, personal digital assistants
and mobile telephones in both the home and office settings, combined with
widespread access to the Internet, have created significant opportunities for
electronic commerce by individual users such as electronic bill payment, home
banking and home shopping.

Fueled by recent and well-publicized incidents including misappropriation of
credit card information and denial of service attacks, there is a growing
perception among many consumers that there is a risk involved in transmitting
information via the Internet. These incidents and this perception may hamper the
development of consumer-based electronic commerce. Accordingly, we believe that
electronic commerce

3

will benefit from the implementation of improved security measures that
accurately identify users and reliably encrypt data transmissions over the
Internet.

COMPONENTS OF SECURITY. Data and financial asset security, and secured
access to and participation in on-line commerce, generally consist of the
following components:

- ENCRYPTION: Maintains data privacy by converting information into an
unreadable pattern and allowing only authorized parties to decrypt the
data. Encryption can also maintain data integrity by creating digital
signatures for transmitted data, enabling the recipient to check whether
the data has been changed since or during transmission.

- IDENTIFICATION AND AUTHENTICATION: Serves as the foundation for other
security mechanisms by verifying that a user is who he or she claims to
be. Identification and authentication mechanisms are often employed with
encryption tools to authenticate users, to determine the proper encryption
key for encrypting/decrypting data or to enable users to digitally "sign"
or verify the integrity of transmitted data.

- ACCESS CONTROL: Software that provides authentication, authorization and
accounting functions, controlling a user's access to only that data or the
financial assets which he or she is authorized to access, and which keep
track of a user's activities after access has been granted.

- ADMINISTRATION AND MANAGEMENT TOOLS: Software which sets, implements and
monitors security policies, the access to which is typically regulated by
access control systems. These tools are extremely important to the overall
effectiveness of a security system.

The most effective security policies employ most, if not all, of the above
components. Most companies, however, only implement a patchwork of these
components, which can result in their security systems being compromised.

THE VASCO SOLUTION

To date, most approaches to network security, including Internet security,
have been limited in scope and have failed to address all of the critical
aspects of data security. We believe that an effective enterprise-wide solution
must address and assimilate issues relating to the following:

- speed and ease of implementation, use and administration;

- reliability;

- interoperability with diverse enterprise environments, existing customer
applications and their diverse security infrastructures;

- scalability; and

- overall cost of ownership.

Accordingly, we have adopted the following approach to data security:

- In designing our products, we have sought to incorporate all
industry-accepted, open and non-proprietary protocols. This permits
interoperability between our products and the multiple platforms,
products, and applications widely in use.

- We have designed our products and services to minimize the integration
effort with, and disruption of, existing legacy applications and security
infrastructures, such as public key infrastructure, known as PKI. We
provide customers with easier implementations and a more rapid means of
implementing security across the enterprise, including the Internet. With
security being a critical enabling technology for online business
initiatives, speed and ease of security implementation has become crucial
to an organization's success.

4

- We design our products and services to have a lower total cost of security
ownership than competing products and services. We have found that product
improvements and tools that lower a customer's total cost of ownership
create differentiating sales and marketing tools, and also help in the
development of a highly loyal customer base that is open to new solutions
that we offer.

As a result of this approach, we believe that we are positioned to be a
leading provider of our open standards-based software and hardware security
solutions.

VASCO'S STRATEGY

We believe we have one of the most complete lines of security products and
services available in the market today and we intend to become a leading
worldwide provider of these products and services. A key element of our growth
strategy is to demonstrate to an increasing number of distributors, resellers
and systems integrators that by incorporating our security products into their
own products they can more effectively differentiate themselves in their
marketplaces and increase the value of their products. In addition, we
demonstrate to our corporate users that our products provide mission critical
security to their internal and external security infrastructures. Following this
aggressive marketing and promotion effort, we work with these resellers and
integrators to support their sales of solutions which include our products.
Also, we plan to expand our direct sales marketing program to new and existing
blue chip customers.

For example, Novell, S-1, Brokat and Intel Network Services (formerly Shiva)
have all built support for our products. We currently market to the distribution
channels of these companies and are already recognizing increasing revenue as
these channels sell our solutions to their end customers. In addition, our
IntelliSoft division has a base of customers we market to directly, such as Duke
University. We are aggressively expanding the use of this strategy world wide.
Further, we intend to:

INCREASE SALES AND MARKETING EFFORTS WORLDWIDE. We intend to increase sales
of our security products and services in our firmly established European markets
and to aggressively increase our sales and support presence and marketing
efforts in North America, South America and Asia. We plan to:

- market new services and products to our existing customers by providing
testimonial evidence of user experiences from other customers;

- launch a worldwide marketing campaign to raise awareness of our solutions
among the decision makers in the security products industry;

- form additional strategic relationships with resellers and vendors of
complementary, innovative security products and systems; and

- develop a marketing and sales infrastructure in new markets, initially
including Hong Kong and Argentina.

CONTINUE INNOVATION. We intend to continue to enhance and broaden our line
of security products to meet the changing needs of our existing and potential
customers by:

- building on our core software and hardware security expertise, such as
expanding our technology for use on different platforms (like mobile
phones and personal digital assistants) and incorporating biometrics into
our products;

- acquiring complementary technologies or businesses; and

- developing additional applications for our products in areas which may
include securing the exchange of data in the healthcare field and
providing security for Internet gambling and lottery transactions, among
others.

VASCO'S PRODUCTS

We operate as two worldwide divisions: IdentiSoft and IntelliSoft. Each
division has its own sales, research and development, and support structures,
while both divisions take advantage of global corporate services such as
marketing, administration, public relations and finance. However, there is
considerable and growing cross-product sales, marketing and development between
the divisions.

The IdentiSoft division is responsible for the development, sales and
support of our Digipass and Cryptech product lines. The IntelliSoft division is
responsible for the development, sales and support of our SnareWorks and VACMAN
product lines.

THE IDENTISOFT DIVISION

Our IdentiSoft division offers software and handheld hardware security
products that provide strong user authentication, thus eliminating the weakest
link in any security scheme, the isolated use of a static password. Over
3,500,000 of our tokens have been sold to over 450 customers. Our largest
customer is Rabobank, which has over 500,000 tokens in use, demonstrating the
scalability of our product. We believe this is the largest token-based
installation of its kind.

IDENTISOFT'S DIGIPASS PRODUCT LINE

Our Digipass product line, which exists as a family of authentication
devices as well as extensive software libraries, provides a flexible and
affordable means of authenticating users to any network, including the Internet.

Security can be broken into three factors:

- What you have (the Digipass device itself);

- What you know (the PIN code to activate the Digipass); and

- Who you are (biometrics).

The Digipass family is currently based on the first two factors. We are
developing voice technology to incorporate the third factor into the Digipass.
Using the Digipass system, in order to enter a remote system or to digitally
sign data one needs:

- the hardware device (the token) itself so that if you do not physically
have the token, you will not be able to log on to the system; and

- the PIN code for the token so if you do not know the appropriate code the
user will not be able to use the applications stored inside.

Both of these factors help to make sure that a natural person is
authenticating (or signing), instead of a computer or another device. These
factors also enable extremely high portability for security anytime, anywhere
and anyhow.

Digipasses calculate dynamic passwords, also known as one-time passwords, to
authenticate users on a computer network and for a variety of other
applications. There are several versions of the Digipass, the 50, 100, 300, 500,
600 and 700, each of which has its own distinct characteristics depending on the
platform that they use and the functions they perform. However, the Digipass
family is designed to work together and customers can switch their users'
devices without requiring any changes to the customers existing infrastructure.
In addition, these devices can be used to calculate digital signatures, also
known as electronic signatures or message authentication codes, to protect
electronic transactions and guarantee the integrity of the contents of these
transactions. In addition, the Digipass 50 is designed to be used on other
platforms such as mobile phones and personal digital assistants.

DIGIPASS AT WORK

[CHART]

[Graphic appears here. Description of contents described in paragraph below.]

The above illustration shows the various steps in the Digipass
initialization process. In the first step the devices are initialized with their
unique set of secrets and keys per device. These secrets are stored in an
encrypted way on a diskette that is sent to the application owner (for example,
the information technology manager in a company or the security department of a
bank). These floppy disks are one way of safely transporting the Digipass
secrets to the host computer.

The files on the floppy disks will be used to read all the necessary secrets
and other data from the delivered Digipasses into a database. Then the
application owner will assign those Digipass secrets to the end-users. This
assignment is based on the serial number of the Digipass and the identity of the
end-user. The Digipass is then shipped to the end-user together with a manual
and, the protected PIN-code on a secure PIN-mailer is sent by a separate
shipment.

7

Using a Digipass requires a connection to the host (server) computer that
knows the parameters of the end-user's Digipass. Every time the user sends a
dynamic password or digital signature to the host computer, the computer will
retrieve all the necessary information from the database and will check the
validity of the password or signature. After the host has checked the validity
of the dynamic password or signature, it will notify the end-user of the
correctness or incorrectness of the validity check.

Digipass security devices are not terminal dependent and do not require any
specific software platform since they only interact with a person.

Currently, the Digipass is used in many applications, the largest of which
is banking. Different banking applications are:

- corporate banking through direct dial-up, as well as over the Internet and

- retail banking to secure transactions made through the use of a dial-up
connection with a personal computer, the traditional phone system, the
Internet, and wireless phones and other communication devices such as
personal digital assistants.

Another significant application for the Digipass is to secure access to
corporate networks for home-based, traveling and other remote users. Finally,
Digipasses are increasingly being used in a variety of e-commerce applications
where the user is part of a pre-defined user group. We intend to expand the use
of the Digipass to other groups of users and applications, including electronic
commerce transactions directed at the general public.

IDENTISOFT'S CRYPTECH PRODUCT LINE. IdentiSoft has a product line that
produces cryptographic microprocessor chips. These chips are used to encrypt
data for use in ATMs, fax machines, modems and security servers at high speeds
using DES and RSA algorithms.

THE INTELLISOFT DIVISION

Our IntelliSoft division, consisting of SnareWorks and VACMAN, offers
enterprise-wide security software that provides encryption, access control and
administration and management tools. Through the product architecture, the
software can be configured to provide security for mainframe, client/server and
Internet applications.

INTELLISOFT'S SNAREWORKS PRODUCT LINE

SnareWorks is uniquely positioned to provide the security bridge between the
existing software infrastructure of legacy mainframe and client-server
applications that are powering large enterprises, and the world of the Web,
e-commerce and business-to-business on the Internet. The critical
differentiating benefit of SnareWorks is that it fits into existing computing
environments transparently because no new programming is required. Not a single
line of application code needs to be modified. As a result of its unique design,
the SnareWorks product line is the only one in the industry that spans all three
architectures (Web, client-server and mainframe) and enables rapid, low-cost,
widespread deployment of true, end-to-end security.

We believe that our competitors' products generally require extensive
customization and integration which requires a complex and time-consuming
deployment effort. In comparison, SnareWorks products are different because of
the following key factors:

- PROTOCOL SUPPORT MODULES. These are small segments of computer code that
represent the knowledge modules that describe the application protocol to
SnareWorks. With these small knowledge modules it is possible to teach
SnareWorks how to apply state-of-the-art security features to existing
applications without requiring any retooling of the applications
themselves.

8

- RAPID AND FLEXIBLE AUTHENTICATION. SnareWorks enables an enterprise to
deploy rapidly a variety of authentication mechanisms, including those
available from competitors, on the desktop.

- TRUE SECURE SINGLE SIGN-ON. Once initial authentication is achieved,
SnareWorks provides single sign-on to a variety of applications, including
web-based and desktop-based applications. In the case of Web-servers, a
user will not have to log into more than a single web server or
application. SnareWorks is different from other competing products because
it can adapt to all commonly deployed authorization and authentication
methodologies.

Additional key features and benefits of the SnareWorks product line are as
follows:

- TRANSPARENT ENCRYPTION. SnareWorks enables strong encryption of all TCP/IP
network traffic on every computer in a network simply by installing it.
When SnareWorks is involved in the transfer of data, the default is
automatically to encrypt all data.

- EASY INSTALLATION. SnareWorks client or desktop software can be downloaded
and installed on desktop computers and web browsers in a matter of
minutes, and do not require additional software or alterations to existing
application software programs. For Internet-based applications that
require only the use of a browser, there is no software to be installed
on, or downloaded to, the user's desktop. This feature significantly
reduces the time, cost and inconvenience to the customer of securing their
networks.

- AUTOMATED USER REGISTRATION. SnareWorks provides an automated process to
register new users by providing them with their network identity along
with their public key certificates without the assistance of a human
administrator. This feature allows large companies to deploy SnareWorks
more rapidly than it would normally take to deploy a solution of this
scope.

- SCALABLE AUTHORIZATION. Users or groups of related users can be granted
access to different portions or applications on a network based upon their
SnareWorks profile. SnareWorks is scalable, allowing a virtually unlimited
number of groups and users to be efficiently handled by the software.
Common groupings of users are made on the basis of their members, roles,
locations and/or time of day, among other factors.

- LOG FILES BASED AUDITING. SnareWorks provides "log files" or detailed
records of the activity surrounding a data transfer, including identity of
user, time, application accessed and date transferred. These log files are
used to monitor and audit network activity by administrators. SnareWorks
can create these files even if the applications or software programs do
not provide for the creation of log files.

- USE OF DIGITAL SIGNATURES. A distinctive feature of SnareWorks is its
ability to significantly enhance the reliability of applications and data
through the use of digital signatures. A digital signature is an authentic
piece of data attached to an object. The recipient as well as a third
party can verify that the object to which the signature is attached has
not been altered since it was signed.

- DISTRIBUTED MANAGEMENT. SnareWorks can be managed from a central location
or from over a dozen graphical management editors and viewers to provide a
comprehensive view of security in the enterprise.

- STANDARDS BASED. SnareWorks supports a wide variety of standard encryption
devices, including DES, 3DES and SSL, digital signatures (RSA), message
integrity (MD5), key management (DCE/ Kerberos, RSA), digital certificates
(X.509), access control (POSIX) and strong authentication (RADIUS).

SNAREWORKS AT WORK

Below is a graphical rendition of how SnareWorks is implemented followed by
a description of each of the elements.

[CHART]

[Graphic appears here. Description of contents described in paragraph below.]

SnareWorks Desktop Client is a thin, ultra-lightweight customer package that
provides a complete security environment for Internet-based applications
residing on a user's desktop. It enables rapid deployment of a comprehensive
security solution to thousands of users across multiple server and operating
system environments. It provides commercial off-the-shelf products and legacy
applications with:

- strong network encryption;

- pluggable authentications;

- a scalable access control model;

- secure single sign-on;

- enforcement of auditing; and

- digital signatures.

SnareWorks Web enables existing Web-based applications to utilize a single
network identity for authentication and true single sign-on. It delivers secure
authorization using a proven access control model, which enables administrators
to control even the most detailed aspects of the Web. SnareWorks Web can be
distributed to multiple Web servers across the enterprise and managed from one
central node through a sophisticated graphical user interface.

The SnareWorks Certificate Server Security Infrastructure provides
certificate management services to the SnareWorks security framework. These
services include issuance, revocation, query and reporting services for
X.509-based certificates. The Certificate Server supports both Web and command
line access to the certificate repository.

10

SnareWorks Rule Server provides the security services necessary to integrate
both Web and non-Web applications into the SnareWorks Framework. These services
include:

- network authentication;

- secure single sign-on;

- fine-grain access control;

- network data encryption;

- auditing;

- event notification; and

- enforcement of numerous other security policies.

The SnareWorks Software Development Kit is a set of library files that a
developer can use to build extensions to the SnareWorks framework. It is used to
develop protocol support modules which enable SnareWorks servers to analyze the
behavior and the operation of legacy applications without requiring these
applications to be modified. Protocol support modules can provide advanced
security features to new or legacy applications. With the SnareWorks Software
Development Kit developers can extend SnareWorks to perform a variety of
functions for these applications, including:

- automatic login and secure single sign-on;

- operation-to-rule mapping;

- object-to-rule mapping;

- identity transformation;

- digital signatures;

- application verification;

- auditing;

- automated keystroke capture;

- chargeback accounting; and

- authorization products interface.

The SnareWorks Security Server is a highly scalable authentication service
that combines the best of security technologies, supporting both secret as well
as public key authentication. It provides signed network credentials that form
the basis for an enterprise-wide authorization infrastructure that can be
applied uniformly to all applications. The Security Server also includes a
distributed database for users, groups, roles, policies, passwords and security
attributes. It also provides encryption services, key generation and
password-strength facilities.

The SnareWorks Administration Console is the control center for the
SnareWorks framework. It enables security administrators to perform remote
management of SnareWorks servers and is also the primary interface for creating
connection and object rules. These rules govern the behavior of all applications
and the access rights to all data throughout the SnareWorks framework. The
Administration Console includes numerous graphical editors, which enable
administrators to control virtually all aspects of SnareWorks from anywhere in
the enterprise.

11

INTELLISOFT AND PUBLIC KEY INFRASTRUCTURE

Many corporations are increasingly relying upon digital certificates to
authenticate and identify users on a network, including the Internet. In
addition, digital certificates are used to transmit data in an encrypted format
over a network. The issuance, revocation, management and policies surrounding
these digital certificates is commonly referred to as public key infrastructure
or PKI. Like any other new comprehensive technology infrastructure, large
companies need to integrate PKI into their legacy and new applications. This
takes time, money, and specialized, hard-to-find personnel. While there may be
significant commercial potential for PKI, the process of integrating PKI into
other enterprise wide applications has proven so difficult that few companies
have existing PKI deployments beyond the pilot stage.

For companies that are using certificate authority vendors such as Entrust,
Baltimore, or Verisign, SnareWorks interoperates and allows for easy integration
of PKI. In addition, for companies that have not committed to a particular
certificate authority vendor, SnareWorks provides its own certificate authority
capabilities. Finally, as described above, SnareWorks can work with non-PKI
related authentication such as tokens, smart cards, and passwords.

We also have patent pending technology that allows for secure storage of a
digital certificate's private key on a server that can be accessed from any
network using any of our Digipass family of products. The effect of this
technology is that it gives digital certificates the portability of PKI deployed
on smartcards, without the cost or infrastructure development required for
deploying smartcards and their associated smartcard readers.

INTELLISOFT'S VACMAN PRODUCT LINE

IntelliSoft's VACMAN product line provides organizations with access control
software to manage secure remote access to computer networks. The product line
consists of the VACMAN Radius Server, the VACMAN Programmer, the VACMAN OPTIMUM
and the VACMAN controller.

Key features of the VACMAN product line are:

- interoperability with a wide range of commercially standard products and
protocols including ODBC databases or any server supporting the RADIUS
standard;

- the ability to program Digipass tokens, giving customers complete control
of the initialization, customization and maintenance processes; and

- the allowance of quick integration of Digipass Authentication software
into industry standard platforms such as Sun Solaris and UNIX.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS AND LICENSES

We rely on a combination of patent, copyright, trademark and trade secret
laws, as well as employee and third-party non-disclosure agreements to protect
our proprietary rights. In particular, we hold several patents in the United
States and a corresponding patent in certain European countries, which cover
certain aspects of our technology. The majority of our patents cover our
Digipass family of security tokens. The U.S. patents expire between 2003 and
2010 and the European patent expires in 2008. We believe these patents to be
valuable property rights and we rely on the strength of our patents and on trade
secret law to protect our intellectual property rights. To the extent that we
believe our patents are being infringed upon, we intend to assert vigorously our
patent protection rights, including but not limited to, pursuing all available
legal remedies.

On March 25, 1998, we entered into an arm's-length license agreement with
Lernout & Hauspie Speech Products N.V. pursuant to which we received a five-year
world-wide, non-exclusive, non-transferable license to use certain speaker
verification software in access control applications. For this license, we

12

agreed to pay a royalty of 10% of revenue associated with the software which
will be credited against royalty prepayments aggregating $800,000. On
December 31, 1998, the license was extended for an additional five years and we
made additional royalty prepayments to reach an aggregate of $1.7 million. In
addition, the revised agreement also provides for the initiation of a
co-marketing and co-sales effort.

Further, in connection with sales of our SnareWorks product, we offer a
SnareTools tool kit pursuant to a perpetual license agreement with Computer
Associates dated December 2, 1996, pursuant to which we pay a 2% royalty based
on net sales of the product. SnareWorks also contains infrastructure software
which is provided by IBM under an original equipment manufacturing agreement
dated October 6, 1999, and by Gradient Technologies under an original equipment
manufacturing agreement dated July 13, 1999. Both of these agreements are for
three-year terms and also provide for small royalty payments based on how our
product is configured with the end users. In the ordinary course of our business
we have entered, and may periodically enter, into license agreements with
software providers, as needed.

RESEARCH AND DEVELOPMENT

Our research and development efforts historically have been, and will
continue to be, concentrated on product enhancement, new technology development
and related new product introductions. We employ 24 full-time engineers and,
from time to time also engage independent engineering firms to conduct non-
strategic research and development efforts on our behalf. For the fiscal years
ended December 31, 1997, 1998 and 1999, we expended $2,313,756, $2,459,477 and
$3,587,483, respectively, on research and development, representing
approximately 17.5%, 14.9% and 18.5% of consolidated revenues for 1997, 1998 and
1999, respectively.

While management is committed to enhancing our current product offerings and
introducing new products, we cannot be certain that our research and development
activities will be successful. Furthermore, we may not have sufficient financial
resources to identify and develop new technologies and bring new products to
market in a timely and cost effective manner, and we cannot ensure that any such
products will be commercially successful if and when they are introduced.

PRODUCTION

Our security hardware products are manufactured by third parties pursuant to
purchase orders that we issue. Our hardware products are made primarily from
commercially available electronic components which are purchased globally. Our
software products are produced either in-house or by several outside sources in
North America and Europe.

The security tokens utilize commercially available programmable
microprocessors, or chips. We use two microprocessors, made by Samsung and
Epson, for the various hardware products we produce. The Samsung microprocessors
are purchased from Samsung Semiconductor in Belgium, and the Epson
microprocessors are purchased from Alcom Electronics NV/SA, also located in
Belgium. The microprocessors are the only components of our security tokens that
are not commodity items readily available on the open market. While there is an
inherent risk associated with each supplier of microprocessors, we believe
having two sources reduces the overall risk to a commercially acceptable level.

Orders of microprocessors and some other components generally require a lead
time of 12 to 16 weeks. We attempt to maintain a sufficient inventory of all
parts to handle short-term increases in orders. Large orders that would
significantly deplete our inventory are typically required to be placed with
more than 12 weeks of lead time, allowing us to attempt to make appropriate
arrangements with our suppliers.

We purchase the majority of our product components and arrange for shipment
to third parties for assembly and testing in accordance with our design
specifications. Our security token products are assembled exclusively by two
independent companies, each of which is based in Hong Kong. Purchases from one
of the companies are made on a purchase order by purchase order basis. Purchases
from the

13

other company are under a contract that extends to January 21, 2001, with
automatic one-year renewals and subject to termination on six months notice.
Each of these companies assembles our security tokens at facilities in mainland
China. One of the companies also maintains manufacturing capacity in Hong Kong.
Equipment designed to test product at the point of assembly is supplied by us
and periodic visits are made by our personnel for purposes of quality assurance,
assembly process review and supplier relations.

There can be no assurance that we will not experience interruptions in the
supply of either the component parts that are used in our products or
fully-assembled token devices in general. In the event that the flow of
components or finished product was interrupted there could be a considerable
delay in finding suitable replacement sources for those components, as well as
in replacement assembly subcontractors with the result that our business and
results of operations could be adversely affected. For further information about
our suppliers, refer to the "Risk Factors" section.

COMPETITION

The market for computer and network security solutions is very competitive
and, like most technology-driven markets, is subject to rapid change and
constantly evolving products and services. With respect to Digipass, our main
competitor is RSA Security Inc., and with respect to our SnareWorks and VACMAN
product lines, our main competitor is Netegrity, Inc. There are many other
companies such as Computer Associates International, Inc., AXENT Technologies,
Inc., ActivCard and Gradient Technologies, Inc. which offer hardware, software
and services that range from simple locking mechanisms to sophisticated
encryption technologies. We believe that competition in this market is likely to
intensify as a result of increasing demand for security products.

We believe that the principal competitive factors affecting the market for
computer and network security products include the strength and effectiveness of
the solution, technical features, ease of use, quality/reliability, customer
service and support, name recognition, distribution channels and price. Although
we believe that our products currently compete favorably with respect to such
factors, other than name recognition in certain markets, there can be no
assurance that we can maintain our competitive position against current and
potential competitors, especially those with significantly greater financial,
marketing, service, support, technical and other competitive resources.

Many of our present and potential competitors have significantly greater
financial, technical, marketing, purchasing and other resources than we do, and
as a result, may be able to respond more quickly to new or emerging technologies
and changes in customer requirements, or to devote greater resources to the
development, promotion and sale of products, or to deliver competitive products
at a lower end user price. Current and potential competitors have established or
may establish cooperative relationships among themselves or with third parties
to increase the ability of their products to address the needs of our
prospective customers. Accordingly, it is possible that new competitors or
alliances may emerge and rapidly acquire significant market share.

Our products are designed to allow authorized users access to a computing
environment, in some cases using patented technology as a replacement for the
static password. Although certain of our security token technologies are
patented, there are other organizations that offer token-type password
generators incorporating challenge-response or response-only approaches that
employ different technological solutions and compete with us for market share.
For additional information regarding our competition, please refer to the
section titled "Risk Factors."

SALES AND MARKETING

Our security solutions are sold worldwide through our direct sales force, as
well as through distributors, resellers and systems integrators. A sales staff
of 24 coordinates our sales through both our sales channels and these strategic
partners' sales channels and makes direct sales calls either alone or with sales
personnel of vendors of computer systems. Our sales staff also provides product
education seminars to

14

sales and technical personnel of vendors and distributors with whom we have
working relationships and to potential end-users of our products.

Part of our expanded selling effort includes approaching our existing
strategic partners to find additional applications for our security products. In
addition, our marketing plan calls for the identification of new business
opportunities that may require enhanced security over the transmission of
electronic data or transactions where we do not currently market our products.
Our efforts also include the preparation and dissemination of white papers
prepared by our support engineers which explain how we believe our security
products can add value or otherwise be beneficial.

Early in the fourth quarter of 1999, we expanded our relationship with
Saatchi & Saatchi to spearhead our worldwide marketing campaign. This worldwide
campaign will include print and media advertising to targeted sectors, as well
as interactive web-based promotional activity.

CUSTOMERS AND MARKETS

Customers for our products include some of the world's most recognized
names. Customers of Digipass tokens include:



BANKING EDUCATION OTHER
- ------- --------- -----

ABN AMRO Bank University of Gronigen Honda Europe
SNS Bank Telindus
Rababank Nederland Pekao Infomatyka
SE Banken


In addition, a growing number of businesses are using SnareWorks and VACMAN.
These include: Duke University.

Cryptech customers are primarily original equipment manufacturers.

In 1999, Concord Eracam Nederland NV accounted for 18% of our revenues. In
addition, we have four other customers who each accounted for 5% or more of our
revenues. We are aware of the risks associated with this degree of customer
concentration and expect to further minimize our reliance on these customers.

EMPLOYEES

As of March 14, 2000, we employed 85 full-time employees, and 1 part-time
employee. Of these, 43 were located in North America and 43 were located in
Europe. Of the total, 44 were involved in sales, marketing and customer support,
21 in product production, research and development and 21 in administration. We
organize internal and external training programs for our employees and reward
employees for obtaining training which benefits their work performance. We had a
total of 80, 60 and 46 employees at the end of the years ended December 31,
1999, 1998 and 1997, respectively.

Our employees are not represented by unions and we have never experienced a
work stoppage. We believe our relationship with our employees is good.

ITEM 2--PROPERTIES

Our corporate offices and North American administrative, sales and
marketing, research and development and support facilities are located in the
United States in an office complex in Oakbrook Terrace, Illinois, a suburb of
Chicago. These facilities are leased through November 30, 2004, and consist of
approximately 9,000 square feet. We believe that the Oakbrook Terrace facilities
will be adequate for our present growth plans.

15

Our European administrative, sales and marketing, research and development
and support facilities are located in a suburb of Brussels, Belgium. These
facilities consist of approximately 23,500 square feet of office space which are
occupied under a lease expiring in September 30, 2005. We believe that these
facilities are adequate for our present growth plans.

ITEM 3--LEGAL PROCEEDINGS

During 1998, the Company was served with a lawsuit filed against it by
Security Dynamics Technologies, Inc. and RSA alleging patent infringement. On
April 6, 1999, Security Dynamics Technologies, Inc., RSA, the Company and VASCO
Data Security, Inc. announced a settlement on confidential terms of the claims
that each of the companies had raised in litigation filed last year.

In addition, the Company is from time to time involved in litigation
incidental to the conduct of its business. The Company is not a party to any
other lawsuit or proceeding which, in the opinion of management, is likely to
have a material adverse effect on the Company's business, financial condition or
results of operations.

ITEM 4--SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matter was submitted to a vote of security holders during the fourth
quarter of 1999, through solicitation of proxies or otherwise.

PART II

ITEM 5--MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

There was no established public market for the Common Stock in 1997. On
March 20, 1998, the Common Stock was approved for trading on the NASD Electronic
Bulletin Board system under the symbol "VDSI."

On March 14, 2000, the closing sale price for the Common Stock on the NASD
Electronic Bulletin Board was $22.88 per share. Such market quotations reflect
inter-dealer prices, without retail mark-up, mark-down or commission and may not
necessarily represent an actual transaction. On March 8, 2000, there were
approximately 111 holders of record of our Common Stock.

Prior to March 23, 1998, shares of VASCO Corp. Common Stock were quoted on
the over-the-counter market under the symbol "VASC." Since March 23, 1998, the
Common Stock has been quoted on the NASD Electronic Bulletin Board under the
symbol "VDSI." The following table sets forth the high and low closing bid
quotations for the securities and periods indicated within the past two fiscal
years.

The Common Stock has been quoted on the NASD Electronic Bulletin Board since
March 23, 1998. The following table sets forth the high and low closing bid

The Company has not paid any dividends on its Common Stock since
incorporation. Dividends were paid relating to the Company's Series B Preferred
Stock, which was converted to Common Stock in September 1997. Restrictions or
limitations on the payment of dividends may be imposed under the terms of credit
agreements or other contractual obligations. In the absence of such restrictions
or limitations, the declaration and payment of dividends will be at the sole
discretion of the Board of Directors of the Company and subject to certain
limitations under the General Corporation Law of the State of Delaware. The
timing, amount and form of dividends, if any, will depend, among other things,
on the Company's results of operations, financial condition, cash requirements,
plans for expansion and other factors deemed relevant by the Board of Directors.
The Company intends to retain any future earnings for use in its business and
therefore does not anticipate paying any cash dividends in the foreseeable
future.

ITEM 7--MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Certain statements contained in the following Management's Discussion and
Analysis of Financial Condition and Results of Operations are forward-looking
statements. All forward-looking statements included herein are based on
information available to the Company on the date hereof and assumptions which
the Company believes are reasonable. The Company does not assume any obligation
to update any such forward-looking statements. These forward-looking statements
involve risks and uncertainties. The

17

Company's actual results could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set
forth elsewhere in this Form 10-K and the Company's other filings with the
Securities and Exchange Commission.

BACKGROUND

Our predecessor company, VASCO Corp., entered into the data security
business in 1991 through the acquisition of a controlling interest in ThumbScan,
Inc., which we renamed VASCO Data Security, Inc. in 1993. In 1996, we began an
expansion of our computer security business by acquiring Lintel Security NV/SA,
a Belgian corporation, including assets associated with the development of
security tokens and security technologies for personal computers and computer
networks. In addition, in 1996, we acquired the stock of Digipass NV/SA, a
Belgian corporation, which was also a developer of security tokens and security
technologies and whose name we changed to VASCO Data Security NV/SA in 1997. All
of these acquisitions were accounted for under the purchase method of
accounting.

On March 11, 1998, we completed a registered Exchange Offer with the holders
of the outstanding securities of VASCO Corp. In the Exchange Offer, holders of
the common stock and warrants, options and other rights to acquire common stock
of our predecessor company exchanged their securities for the same number and
kind of securities of our present company, and released any potential claims
that such holders might have had against our predecessor in connection with the
issuances of its securities and other corporate actions which occurred mostly
during the 1980's. In the Exchange Offer, almost 98% of our predecessor's
securities were tendered and accepted for exchange. In October 1998, we
completed the merger of our predecessor with and into the current company and
thereby eliminated all remaining outstanding securities of our predecessor and
our predecessor thereby ceased to exist.

Since the Exchange Offer, we have engaged in two acquisitions. In May 1999,
we acquired the assets of SecureWare SA, a French company for a combination of
approximately $1.4 million in our stock and cash.

Our latest acquisition occurred in October of 1999 when we acquired
Intellisoft Corp. for a combination of approximately $8 million in our stock and
cash distributed to dissenting shareholders. This acquisition was accounted for
under the pooling-of-interests method of accounting and, therefore, all of our
financial information has been restated to include the results of IntelliSoft.

As a result of all of our acquisitions, our legal structure includes five
wholly-owned subsidiaries. Shortly after our acquisition of IntelliSoft, we
organized our operations into two business divisions, IdentiSoft and
IntelliSoft.

OVERVIEW

We design, develop, market and support security products and services which
manage and protect against unauthorized access to computer systems of corporate
and governmental clients.

REVENUE AND EARNINGS. We sell the majority of our products in European
countries with significant sales in the United States, although we intend to
actively pursue additional markets outside of Europe, particularly Asia and
North and South America.

Revenues from sales from our Digipass family, specifically the Digipass 300
and 500 tokens, continue to represent the majority of our total revenues. In
excess of 80% of our sales for 1999 were comprised of security token devices.
Although we believe it is likely that sales of the Digipass family of tokens,
which can be used on various platforms, will continue to account for a majority
of our total revenues for the next few years, we also believe that revenues from
sales of our other hardware and software data security products, including the
additional product offerings made by our IntelliSoft division, will continue to
increase in the future.

18

Concord-Eracom Nederland BV accounted for 15%, 12% and 18% of our sales in
1997, 1998 and 1999, respectively. It is expected that consolidated sales to
other customers and markets will increase and, that the degree of concentration
attributable to this major customer will decrease.

RESEARCH AND DEVELOPMENT. We are devoting substantial capital and other
resources to enhancing our existing security products and developing new
products to provide enterprise-wide hardware and software security solutions.
Costs of research and development, principally the design and development of
hardware and software prior to the determination of technological feasibility,
are expensed as incurred on a project-by-project basis. Our software
capitalization policy currently defines technological feasibility as a
functioning beta test prototype with confirmed manufacturability (a working
model), within a reasonably predictable range of costs. Additional criteria
include receptive customers, or potential customers, as evidenced by interest
expressed in a beta test prototype, at some suggested selling price.

VARIATIONS IN OPERATING RESULTS. Our quarterly operating results have in
the past varied and may in the future vary significantly. Factors affecting
operating results include:

- the level of competition;

- the size, timing, cancellation or rescheduling of significant orders;
market acceptance of new products and product enhancements;

- new product announcements or introductions by our competitors;

- adoption of new technologies and standards; changes in pricing by us or
our competitors;

- our ability to develop, introduce and market new products and product
enhancements on a timely basis, if at all;

- component costs and availability;

- our success in expanding our sales and marketing programs;

- technological changes in the market for data security products;

- foreign currency exchange rates;

- and general economic trends and other factors.

19

In addition, we have experienced, and may experience in the future, long
sales cycles due to the size of our contracts and the timing of when our
customers take delivery of our products. We also experience seasonality in our
business. While these seasonal trends have included higher revenue in the last
quarter of the calendar year and lower revenue in the next succeeding quarter,
this was not the case in 1999 as a result of our customers' year 2000 concerns
and resulting purchasing decisions. We believe that revenue has tended to be
higher in the last quarter due to the tendency of certain customers to implement
or complete changes in computer or network security prior to the end of the
calendar year. In addition, revenue has tended to be lower in the summer months,
particularly in Europe, when many businesses defer purchase decisions. Because
our operating expenses are based on anticipated revenue levels and a high
percentage of our expenses are fixed, a small variation in the timing of
recognition of revenue could cause significant variations in operating results
from quarter to quarter.

CURRENCY FLUCTUATIONS. The majority of our supply and sales transactions
are denominated in U.S. dollars, however a significant portion of those
transactions are denominated in various foreign currencies. In order to reduce
the risks associated with fluctuations in currency exchange rates, we attempt to
match the timing of delivery, amount of product and the currency denomination of
purchase orders received from vendors with sales orders to customers.

RESULTS OF OPERATIONS

The following table sets forth, for the periods indicated, certain
consolidated financial data as a percentage of revenues for the years ended
December 31, 1997, 1998 and 1999.

===== ===== =====


The following discussion is based upon our consolidated results of
operations for the years ended December 31, 1999, 1998 and 1997 (percentages in
the discussion are rounded to the closest full percentage point) and should be
read in conjunction with our consolidated financial statements included
elsewhere in this Form 10-K.

20

1998 COMPARED TO 1999

REVENUES

Our consolidated net revenues for the year ended December 31, 1999 were
$19,397,000, an increase of $2,897,000, or 18%, as compared to the year ended
December 31, 1998. This increase is due to a strong demand for Digipass 300 and
Digipass 500 as well as SnareWorks and VACMAN. In addition to the strong demand
for our products, we have had less volume discounting.

COST OF GOODS SOLD

Our consolidated cost of goods sold for the year ended December 31, 1999 was
$7,306,000, an increase of $97,000, or 1%, as compared to the year ended
December 31, 1998. Cost of goods sold has not increased at the same rate as our
revenues due to efficiencies in the manufacturing process, as well as increased
sales of products with a more favorable cost structure.

GROSS PROFIT

Our consolidated gross profit for the year ended December 31, 1999 was
$12,091,000, an increase of $2,800,000, or 30%, over the year ended
December 31, 1998. This represents a gross margin of 62%, as compared to 1998's
consolidated gross margin of 56%. The increase in gross margin is due to
efficiencies in manufacturing related to increasing volumes, an increase in the
mix of sales of higher margin products, as well as less volume discounting.

SALES AND MARKETING EXPENSES

Consolidated sales and marketing expenses for the year ended December 31,
1999 were $5,962,000, an increase of $1,189,000, or 25%, over 1998. This
increase can be attributed to increased sales efforts including, in part,
increased travel costs, headcount, and an increase in marketing activities,
including tradeshows. Additionally, the acquisition of IntelliSoft in
October 1999 resulted in additional headcount, as the sales operations were
expanded in the fourth quarter of 1999.

RESEARCH AND DEVELOPMENT EXPENSES

Consolidated research and development costs for the year ended December 31,
1999 were $3,587,000, an increase of $1,128,000, or 46%, as compared to the year
ended December 31, 1998. This increase is, in part, related to the acquisition
of SecureWare during 1999. As SecureWare is primarily a development center, the
acquisition resulted in increased research and development headcount and
expenditures. During 1999, the IntelliSoft division increased research and
development headcount and expenditures. Additionally, during 1999, we entered
into a development agreement with Intel Network Systems, Inc. related to the
further enhancement of the VACMAN product line.

GENERAL AND ADMINISTRATIVE EXPENSES

Consolidated general and administrative expenses for the year ended
December 31, 1999 were $3,435,000, an increase of $50,000, or 1%, over 1998.
This increase can be attributed to growth in infrastructure needed to support
our growth, as well as the impact of the acquisition of SecureWare during 1999.

INTEREST EXPENSE

Consolidated interest expense in 1999 was $815,000 as compared to $1,458,000
in 1998. The decrease can be attributed to a lower borrowing base being
maintained during 1999 as compared to the prior year.

21

INCOME TAXES

We recorded tax expense for the year ended December 31, 1999 of $322,000,
which relates to one of our European subsidiaries.

At December 31, 1999, we have United States net operating loss carryforwards
approximating $9,100,000 and foreign net operating loss carryforwards
approximating $1,500,000. Such losses are available to offset our future taxable
income in the respective jurisdictions and expire in varying amounts beginning
in 2002 and continuing through 2019. In addition, if certain substantial changes
in our ownership are deemed to have occurred, there would be an annual
limitation on the amount of the U.S. carryforwards which could be utilized.

1997 COMPARED TO 1998

REVENUES

Our consolidated revenues for the year ended December 31, 1998 were
$16,500,000, an increase of $3,292,000, or 25%, as compared to the year ended
December 31, 1997. The European operations contributed $12,231,000 or 74% of
total consolidated revenues, with the United States operations contributing the
remaining $4,269,000 or 26%. This increase is due to a strong performance from
international operations, as the demand for Digipass 300 and Digipass 500
continues to grow. This resulted in increased unit sales, as well as an increase
of orders with smaller quantities, resulting in fewer volume discounts. In
addition, we benefited from currency exchange rates.

COST OF GOODS SOLD

Our consolidated cost of goods sold for the year ended December 31, 1998 was
$7,209,000, an increase of $720,000, or 11%, as compared to the year ended
December 31, 1997. The European operations' cost of goods sold was $5,550,000 or
77% of total consolidated cost of goods sold and the United States operations'
cost of goods sold was $1,659,000 or 23% of total consolidated cost of goods
sold. This increase is consistent with the increase in revenues for the year. We
continue to benefit from efficiencies in the manufacturing process, as well as
the increasing demand for products with a more favorable cost structure.

GROSS PROFIT

Our consolidated gross profit for the year ended December 31, 1998 was
$9,291,000, an increase of $2,572,000, or 38%, over the year ended December 31,
1997. This represents a gross margin of 56%, as compared to 1997's consolidated
gross margin of 51%. The increase in gross margin is due to efficiencies in
manufacturing related to increasing volumes, an increase in the mix of higher
margin products, as well as increasing orders with smaller quantities, resulting
in less volume discounting.

SALES AND MARKETING EXPENSES

Consolidated sales and marketing expenses for the year ended December 31,
1998 were $4,773,000, an increase of $1,084,000, or 29%, over 1997. This
increase can be attributed to increased sales efforts including, in part,
increased travel costs, headcount, and an increase in marketing activities,
including the development of a VASCO logo, Internet web page and other efforts.

RESEARCH AND DEVELOPMENT EXPENSES

Consolidated research and development costs for the year ended December 31,
1998 were $2,459,000, an increase of $145,000, or 6%, as compared to the year
ended December 31, 1997. This increase can be attributed to increased headcount
and expenditures related to IntelliSoft during 1998 as compared to 1997.

22

GENERAL AND ADMINISTRATIVE EXPENSES

Consolidated general and administrative expenses for the year ended
December 31, 1998 were $3,385,000, a decrease of $1,499,000, or 31%, compared to
1997. This decrease can be attributed to the fact that we were preparing for the
Exchange Offer during 1997, thus generating significant legal, accounting and
printing expenses; the Exchange Offer was completed during March 1998. In
addition, economies of scale began to be realized during 1997 as a result of the
combination of the operations of Lintel Security and VASCO Data Security. In
1998, we also recorded recoveries of bad debts and a reduction of certain legal
fees associated with the Exchange Offer.

INTEREST EXPENSE

Consolidated interest expense in 1998 was $1,458,000 compared to $1,148,000
in 1997. The increase can be attributed to average borrowings in 1998 being
higher than those of the previous year.

INCOME TAXES

We recorded tax expense for the year ended December 31, 1998 of $687,000,
which consisted of a tax benefit related to one of our European operations.

DIVIDENDS

We paid no dividends during the year ended December 31, 1998 and $82,000
during the year ended December 31, 1997, respectively. The 1997 dividend
payments were attributable to 9,000 shares of VASCO Series B Preferred Stock
issued in 1994. During 1997, all 9,000 shares of VASCO Series B Preferred Stock
were converted into VASCO Data Security International, Inc. Common Stock.

RECENT DEVELOPMENTS

On January 27, 2000, we filed for the listing of our Common Stock on the
Nasdaq National Market. Additionally, on February 11, 2000, we filed with the
SEC for a public offering of our common stock for approximately $50,000,000. In
connection with this offering, filings were made with the EASDAQ and the Nasdaq
Stock Market.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 1999, our aggregate consolidated indebtedness was
$9,048,000. Cash used in operating activities was $1,612,000 for the year ended
December 31, 1999. During that period we used $1,483,000 in investing activities
and financing activities provided $3,988,000. Capital expenditures were $895,000
for the year ended December 31, 1999.

In 1996, we issued a 9% convertible note to Kyoto Securities, Ltd., a
Bahamian corporation, in the amount of $5,000,000. The note provides for
quarterly interest payments and is payable in full on May 29, 2001. The note is
convertible into shares of our Common Stock at a conversion price of $12.00 per
share, or 416,667 shares. On March 10, 2000, we received a notice to convert the
note.

In 1997, we entered into a convertible loan agreement with Artesia Bank
N.V., formerly Banque Paribas Belgique S.A., in order to refinance the
$3,400,000 payment due December 31, 1997 in connection with our acquisition of
Digipass. The terms of the agreement provide that the $3,400,000 principal
amount is convertible, at the option of the lender, into shares of our Common
Stock. This loan bears interest at the rate of 3.25%, payable annually, and
matures on September 30, 2002. After January 1, 1999, the loan is convertible at
the average closing market price for shares of our Common Stock on the NASD
Electronic Bulletin Board system for the 20 trading days prior to the date of
the notice of conversion, less 10%. In the event a public offering is completed,
the lender may at its option (by written notice within seven days after our
receipt of the proceeds of the public offering) require the principal amount of
the loan to be repaid in

23

cash, in which case additional special interest is payable as follows: $680,000
if repayment is on January 1, 1999 or later. As part of this transaction, Mr.
T. Kendall Hunt, our former Chief Executive Officer, entered into a pledge
agreement with Banque Paribas Belgique S.A., pursuant to which he pledged, as
collateral for the convertible note, 1,416,666 of his shares of Common Stock,
which number of shares is subject to adjustment based on the market value of the
shares.

The net effect of 1999 activity resulted in an increase in cash of $914,000,
resulting in a cash balance of $2,576,000 at December 31, 1999, compared to
$1,662,000 at the end of 1998. Our working capital at December 31, 1999 was
$2,473,000, an increase of $6,207,000, or 166% from ($3,734,000) at
December 31, 1998. The majority of the change is attributable to a 54% decrease
in current liabilities, mainly due to the current maturities of long-term debt.
Our current ratio was 1.5 to 1.0 at December 31, 1999.

In April 1999, we completed a private placement of Common Stock in the
amount of $11.5 million. The transaction represented a sale of our Common Stock
to European institutional investors at a price of $3.50 per share. A total of
3,285,714 shares of Common Stock were issued as a part of this transaction. We
believe that the proceeds that will be raised from our proposed stock offering,
along with our current cash balances and anticipated cash generated from
operations will be sufficient to meet our anticipated cash needs for the
foreseeable future.

We intend to seek acquisitions of businesses, products and technologies that
are complementary or additive to ours. There can be no assurance that any such
acquisitions will be made.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

During 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" (as amended by SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133"), which is effective for all fiscal years beginning after
June 15, 2000. SFAS No. 133 establishes a comprehensive standard for the
recognition and measurement of derivative instruments and hedging activities. We
do not expect the adoption of the new standard to have a material effect on our
consolidated financial position, liquidity, or results of operations.

ITEM 7A--QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Approximately 63% of our business is conducted outside the United States, in
Europe and Asia/ Pacific. A significant portion of our business operations are
transacted in foreign currencies. As a result, we have exposure to foreign
exchange fluctuations. We are affected by both foreign currency translation and
transaction adjustments. Translation adjustments result from the conversion of
the foreign subsidiaries' balance sheets and income statements to U.S. dollars
at year-end exchange rates and weighted average exchange rates, respectively.
Translation adjustments resulting from this process are recorded directly into
stockholders' equity. Transaction adjustments result from currency exchange
movements when a foreign subsidiary transacts business in a currency that
differs from its local currency. These transactions are recorded as gains or
losses in our statement of operations.

Our foreign exchange exposure was minimized in 1999 as the majority of our
foreign subsidiaries' business transactions were spread across approximately 40
different countries and currencies. This geographic diversity reduces the risk
to our operating results. Also, we perform periodic reviews of outstanding
balances and settle intercompany accounts to minimize foreign exchange
transaction gains and losses.

We have minimal interest rate risk. Our $8.4 million long-term debt is made
up of fixed rate notes, ranging from 3.25% to 9%, which are not subject to
market fluctuations. The maturities of these notes range from 2001 to 2002.

INDEPENDENT AUDITORS' REPORT

The Stockholders and Board of Directors
VASCO Data Security International, Inc.:

We have audited the accompanying consolidated balance sheets of VASCO Data
Security
International, Inc. and subsidiaries (the "Company") as of December 31, 1998 and
1999 and the related consolidated statements of operations, comprehensive loss,
stockholders' deficit, and cash flows for each of the years in the three-year
period ended December 31, 1999. In connection with our audits of the
consolidated financial statements, we have also audited the accompanying
consolidated financial statement Schedule II--Valuation and Qualifying Accounts.
These consolidated financial statements and the
consolidated financial statement schedule are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements and the consolidated financial statement
schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of VASCO Data
Security International, Inc. and subsidiaries as of December 31, 1998 and 1999,
and the results of their operations and their cash flows for each of the years
in the three-year period ended December 31, 1999, in conformity with generally
accepted accounting principles. Also, in our opinion, the related consolidated
financial statement schedule, when considered in relation to the basic
consolidated financial statements taken as a whole, presents fairly, in all
material respects, the information set forth therein.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

VASCO Data Security International, Inc. and its wholly owned subsidiaries
(the Company) designs, develops, markets and supports security products and
services which manage and protect against unauthorized access to computer
systems of corporate and government customers.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of VASCO Data
Security International, Inc. and its wholly owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.

FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS

The financial position and results of operations of the Company's foreign
subsidiaries are measured using the local currency as the functional currency.
Accordingly, assets and liabilities are translated into U.S. dollars using
current exchange rates as of the balance sheet date. Revenues and expenses are
translated at average exchange rates prevailing during the year. Translation
adjustments arising from differences in exchange rates are included as a
separate component of stockholders' deficit. Gains and losses resulting from
foreign currency transactions are included in the consolidated statements of
operations. Foreign exchange transaction losses aggregating $12,000, $174,000
and $272,000 are included in other non-operating expense for 1997, 1998, and
1999, respectively

REVENUE RECOGNITION

The American Institute of Certified Public Accountants Statement of Position
97-2, "Software Revenue Recognition" (SOP 97-2) was issued in October 1997 and
is effective for transactions entered into in fiscal years beginning after
December 15, 1997. SOP 97-2 addresses various aspects of the recognition of
revenues on software transactions and supersedes SOP 91-1, the policy previous
followed by the Company. The Company adopted SOP 97-2 in fiscal year 1998,
beginning January 1, 1998. The adoption of this statement has not resulted in a
material impact on the Company's financial statements.

LICENSE FEES. Revenues from the sale of computer security hardware and
software are recorded upon shipment or, if an acceptance period is allowed, at
the later of shipment or customer acceptance. No significant obligations exist
with regard to delivery or customer acceptance at the time of recognizing
revenue.

SUPPORT AGREEMENTS. Support agreements generally call for the Company to
provide technical support and software updates to customers. Revenue on
technical support and software update rights is recognized ratably over the term
of the support agreement.

CONSULTING AND EDUCATION SERVICES. The Company provides consulting and
education services to its customers. Revenue from such services is generally
recognized during the period in which the services are performed.

PREPAID ROYALTIES

On March 25, 1998, the Company entered into a license agreement with
Lernout & Hauspie Speech Products N.V. pursuant to which the Company received a
five-year worldwide, non-exclusive, non-transferable license to use certain
speaker verification software in access control applications. For this license,
the Company agreed to pay a royalty of 10% of revenue associated with the
software which will be credited against royalty prepayments aggregating
$800,000. On December 31, 1998, the license was

F-7

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
extended for an additional five years and the Company made royalty prepayments
to reach an aggregate of $1,700,000. Prepaid royalties amounted to $600,000 and
$1,700,000 at December 31, 1998 and 1999, respectively. Amortization of the
royalty prepayments will commence during the second quarter of 2000 when the
applications incorporating the Lernout & Hauspie software are released to the
general public.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the related assets
ranging from three to seven years. Additions and improvements are capitalized,
while expenditures for maintenance and repairs are charged to operations as
incurred. Gains or losses resulting from sales or retirements are recorded as
incurred, at which time related costs and accumulated depreciation are removed
from the accounts. "

SOFTWARE COSTS

The Company capitalizes software development costs in accordance with
Statement of Financial Accounting Standards (SFAS) No. 86, "Accounting for the
Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed". Research
and development costs, prior to the establishment of technological feasibility,
determined based upon the creation of a working model, are expensed as incurred.
The Company's policy is to amortize capitalized costs by the greater of (a) the
ratio that current gross revenues for a product bear to the total of current and
anticipated future gross revenues for that product or (b) the straight-line
method over the remaining estimated economic life of the product, generally two
to five years, including the period being reported on.

INCOME TAXES

Income taxes are accounted for under the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The following disclosures of the estimated fair value of financial
instruments are made in accordance with the requirements of SFAS No. 107,
"Disclosures and Fair Value of Financial Instruments." The estimated fair value
amounts have been determined by the Company using available market information
and appropriate valuation methodologies. The fair values of the Company's
financial instruments were not materially different from their carrying amounts
at December 31, 1998 and 1999, except for notes payable and long-term debt, for
which the fair values were not determinable.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

F-8

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
RECLASSIFICATIONS

Certain amounts in the consolidated financial statements have been
reclassified to confirm to the 1999 presentation.

GOODWILL AND OTHER INTANGIBLES

Goodwill is amortized on a straight-line basis over the expected period to
be benefited, which is seven years. Other intangibles are amortized on a
straight-line basis and consist of software and hardware technology which is
being amortized over a period of four years and workforce and customer lists
which are being amortized over a period of seven years.

The Company periodically evaluates whether events and circumstances that
have occurred indicate that the remaining balance of goodwill and other
intangibles may not be recoverable or that the remaining estimated useful lives
may warrant revision. When such factors indicate that goodwill and other
intangibles should be evaluated for possible impairment, the Company uses an
estimate of undiscounted future cash flows to measure whether the goodwill and
other intangibles are recoverable.

STOCK-BASED COMPENSATION

On January 1, 1996, the Company adopted SFAS No. 123, "Accounting for
Stock-Based Compensation," which permits entities to recognize the compensation
expense associated with the fair value of all stock-based awards on the date of
grant. Alternatively, SFAS No. 123 allows entities to continue to apply the
provisions of Accounting Principles Board (APB) Opinion No. 25, "Accounting for
Stock Issued to Employees," and provide pro forma disclosures as if the fair
value method defined in SFAS No. 123 had been applied. The Company has elected
to apply the provisions of APB Opinion No. 25 and provide the pro forma
disclosures required by SFAS No. 123.

LOSS PER COMMON SHARE

Basic earnings per share is based on the weighted average number of shares
outstanding and excludes the dilutive effect of unexercised common stock
equivalents. Diluted earnings per share is based on the weighted average number
of shares outstanding and includes the dilutive effect of unexercised common
stock equivalents to the extent they are not anti-dilutive.

Shares issuable from securities that could potentially dilute basic earnings
per share in the future that were not included in the computation of earnings
per share because their effect was anti-dilutive were as follows at
December 31:

* Due to the contingent nature of the conversion feature of these notes, a
20-day average market price was used to calculate the number of potentially
dilutive shares.

F-9

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Additionally, the net loss applicable to common stockholders for the years
ended December 31, 1997, 1998 and 1999 would have been decreased by adding back
interest expense related to the convertible notes of approximately $980,000,
$1,394,000 and $704,000, respectively.

NOTE 2--ACQUISITIONS

Effective May 1, 1999, the Company acquired substantially all of the assets
of SecureWare SA and DMIC SA (SecureWare), as well as certain developed software
licenses from the founder of SecureWare in exchange for $738,735 in cash (of
which $151,203 is recorded in accrued liabilities at December 31, 1999) plus
174,575 shares of the Company's common stock, which had a market value based
upon the trading price of the common stock on the Nasdaq Bulletin Board ("Market
Value") of approximately $650,000 at the time of the acquisition. SecureWare,
located in Bordeaux, France, is a software developer focusing on developing
security solutions for a number of operating systems.

The acquisition of SecureWare was accounted for under the purchase method of
accounting, and accordingly, the acquired assets have been recorded at their
estimated fair values at the date of acquisition. Purchased software related to
this transaction was $889,000 and is being amortized over a period of five
years. Goodwill related to this transaction was $406,000 and is being amortized
over a period of seven years. The remaining purchase price is related to
acquired fixed assets. The effect on the pro forma results of operations had the
acquisition occurred at the beginning of 1999 was immaterial.

On October 6, 1999, the Company acquired all of the outstanding capital
stock of IntelliSoft Corp. (IntelliSoft) in exchange for 1,812,078 shares of
common stock, which had a Market Value of approximately $7,250,000 at the time
of the acquisition. In addition, the Company paid $751,575 to IntelliSoft
dissenters to acquire their capital stock interests, which represented 9.4% of
the outstanding capital stock of IntelliSoft at the date of the acquisition. The
acquisition of these shares has been treated as the purchase and retirement of
common stock. IntelliSoft, located in Acton, MA, specializes in developing true
secure single sign-on, Web authorization, PKI, VPN, and enterprise management
solutions. This transaction was accounted for under the pooling-of-interests
method. Accordingly, the consolidated financial statements have been restated as
if IntelliSoft had been combined for all periods presented.

The following information reconciles total revenues and net loss of the
Company as previously reported in the Company's Annual Report on Form 10-K for
the years ended December 31, 1997 and 1998 with the amounts presented in the
accompanying consolidated statements of operations for the years

carryforwards approximating $9,100,000 and foreign net operating loss
carryforwards approximating $1,400,000. Such losses are available to offset
future taxable income in the respective jurisdictions and expire in varying
amounts

$676,000, respectively. In assessing the realizability of deferred tax assets,
the Company considers whether it is more likely than not that some portion or
all of the deferred tax assets will be realized. The ultimate realization of
deferred tax assets is dependent upon the generation of future taxable income
during the period in which these temporary differences become deductible. This
assessment was performed considering the scheduled reversal of deferred tax
liabilities, projected future taxable income, and tax planning strategies. The
Company has determined that it is more likely than not that $83,000 of deferred
tax assets will be realized. The remaining valuation allowance of $4,121,000 is
maintained on deferred tax assets which the Company has not determined to be
more likely than not realizable as of December 31, 1999. This valuation
allowance will be reviewed on a regular basis and adjustments made as
appropriate.

========== ==========


In August 1997, the Company renegotiated the guarantee related to the final
payment for the 1996 acquisition of Digipass into a term loan in the amount of
$3.4 million. The note matures on September 30, 2002 and bears interest at a
rate of 3.25% annually. In the event a public offering is completed, the lender
may at its option require the principal amount of the loan to be repaid in cash,
in which case the Company must pay additional special interest in the amount of
$680,000. In addition, the note is convertible into common stock of the Company
at the option of the bank, at a conversion price as specified in the agreement.
As part of this transaction, T. Kendall Hunt, then the Company's Chief Executive
Officer, entered into a pledge agreement with this financial institution
pursuant to which he pledged, as collateral for the convertible note, 1,416,666
of his shares of common stock of the Company, which number of shares is subject
to adjustment based on the market value of the shares.

During 1996, the Company continued to raise capital privately, including a
private placement consisting of the issuance of 666,666 shares of common stock
and a $5,000,000 convertible note due May 29, 2001. The note is convertible at
the option of the holder throughout the term of the note and is convertible at
the option of the Company in the event that the Company completes a qualified
public offering. The note bears interest at 9%, with interest payable to the
holder on a quarterly basis. The holder may, at its option, elect to receive
interest payments in cash or common stock. In calculating the shares of common
stock to be issued in lieu of cash interest, the average closing price for the
Company's common stock for the previous 20 days is used.

Aggregate maturities of debt at December 31, 1999 are as follows:



2000........................................................ $ 639,322
2001........................................................ 5,008,862
2002........................................................ 3,400,000
----------
Total................................................. $9,048,184
==========


Interest expense to stockholders was $507,100, $497,795 and $450,000 for the
years ended December 31, 1997, 1998 and 1999, respectively.

NOTE 7--STOCKHOLDERS' EQUITY

COMMON STOCK

During 1999, the Company issued 174,575 shares of common stock as part of
the acquisition of SecureWare and 1,812,078 shares of common stock as part of
the acquisition of IntelliSoft (see Note 2).

F-14

The Company also raised additional capital during 1999 in a private placement of
3,285,714 shares of common stock at a price of $3.50 per share. Total issuance
costs of $763,074 have been netted against the $11,500,000 in proceeds from the
placement in the Company's financial statements.

Also in 1999, the Company issued 158,000 shares of common stock as a result
of the exercise of options under the Company's stock compensation plan (see
Note 8) generating total proceeds of $44,225; 200,000 shares of common stock
were issued as a result of the exercise of the Company's stock warrants,
generating total proceeds of $50,000; and 26,019 shares of common stock were
issued in lieu of interest that was accrued at December 31, 1998, related to the
$5,000,000 convertible note placed during 1996 (see Note 6).

During 1998, the "put" option associated with a 1995 private placement of
equity units expired, resulting in the reclassification of the put obligation to
additional paid-in capital.

During 1998, the Company issued 658,257 shares of common stock as a result
of the exercise of options under the Company's stock option plan (see Note 8)
generating total proceeds of $116,347; 14,472 shares of common stock were issued
as a result of the exercise of the Company's stock warrants, under the cashless
exercise provision contained within the warrant.

NOTE 8--STOCK COMPENSATION PLAN

The Company's 1997 Stock Compensation Plan, as amended, ("Compensation
Plan") is designed and intended as a performance incentive. The Compensation
Plan is administered by the Compensation Committee as appointed by the Board of
Directors of the Company (Compensation Committee).

The Compensation Plan permits the grant of options to employees of the
Company to purchase shares of common stock and is intended to be a nonqualified
plan. All options granted to employees are for a period of ten years, are
granted at a price equal to the fair market value of the common stock on the
date of the grant and are typically vested 20% on the first anniversary of the
grant, with an additional 20% vesting on each subsequent anniversary of the
grant. Alternative vesting schedules include either date or event-based vesting.

The Compensation Plan further permits the grant of options to directors,
consultants and other key persons (non-employees) to purchase shares of common
stock. All options granted to non-employees are

F-15

granted at a price equal to the fair market value of the common stock on the
date of the grant, and may contain vesting requirements and/or restrictions as
determined by the Compensation Committee at the time of grant.

As of December 31, 1999, the Compensation Plan was authorized to issue
options representing up to 5,292,417 shares of the Company's common stock. The
authorized shares under the Compensation Plan represent 20% of the issued and
outstanding shares of the Company.

The Company applies APB Opinion No. 25 and related interpretations in
accounting for the Compensation Plan. Had compensation cost for the Compensation
Plan been determined consistent with SFAS No. 123, the Company's net loss
available to common stockholders and net loss per common share would have been
the pro forma amounts indicated below:



FOR THE YEAR ENDED DECEMBER 31,
---------------------------------------
1997 1998 1999
----------- ----------- -----------

Net loss available to common stockholders:
As reported.......................................... $(6,241,639) $(3,782,012) $(2,212,484)
Pro forma............................................ (6,514,741) (4,126,931) (2,789,233)
Net loss per common share-basic and diluted:
As reported.......................................... $ (0.30) $ (0.17) $ (0.09)
Pro forma............................................ (0.31) (0.18) (0.11)


For purposes of calculating the compensation cost consistent with SFAS
No. 123, the fair value of each option grant is estimated on the date of grant
using the Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants in 1997, 1998 and 1999: dividend yield of 0%;
expected volatility of 50%; risk free interest rates ranging from 4.00% to
6.80%; and expected lives of five years.

The following is a summary of activity under the Compensation Plan:
