General

We, through our operating subsidiaries, design, develop, market
and support open standards-based hardware and software security systems that manage and secure access to information assets. We design, develop, market and support patented Strong User Authentication and PKI (Public Key
Infrastructure) products and services for employee and consumer security, e-business and e-commerce. Our products enable secure financial transactions to be made over private enterprise networks and public networks, such as the Internet.

The backbone of our product range is VACMAN Controller. VACMAN Controller is either integrated into or interfaced with the host
systems application. VACMAN Controller supports multiple authentication technologies, including passwords, dynamic password technology, electronic signatures, digital signatures, certificates and biometrics, on one unique platform.

Our client side strong user authentication is delivered via our hardware and software DIGIPASS security products, (collectively
DIGIPASSES) most of which incorporate an electronic signature capability, which further protects the integrity of electronic transactions and data transmissions. Some of our DIGIPASSES are compliant with the Europay MasterCard Visa (EMV)
standard and are compatible with MasterCards and VISAs Chip Authentication Program (CAP). Some of our DIGIPASS units are OATH (Initiative for Open Authentication) compliant.

Our strategy is to be the full option, all-terrain authentication company. Our end-to-end authentication combines all aspects of
VASCOs longstanding full option, all-terrain business model. Based on one unique core authentication engine, VACMAN, VASCO offers a wide portfolio of over 50 software and hardware client authentication products and services, for Banking and
non-Banking markets. As such, VASCO secures a network from the server to the end-user.

In early 2010, we launched our
DIGIPASS as a Service (DaaS) business model. With DaaS, we will offer our customers the opportunity to secure all of their software as service business applications with one single DIGIPASS authentication credential.

##### Table of Contents

In a second phase of DaaS, we plan to secure a multitude of a consumers online
accounts with one DIGIPASS credential. Thus, end users will be able to get secure access to, among other things, their private email accounts, their frequent flyer information and their social networking pages, as well as securely buy goods, order
tickets, and play their favorite e-game on the Internet. We believe that with this approach, VASCO brings best-of-breed authentication into the reach of almost every online application.

VASCOs product lines include:

Our target
markets are the applications and their several hundred million users that utilize fixed passwords as security. Our event and time-based system generates one-time passwords that change with every use and electronic signatures that protect
transactions. As a result, when compared to fixed passwords, it substantially reduces the risks of unauthorized access to the application and of the hijacking of financial or other data transfers over the Internet.

Our security solutions are sold worldwide through our direct sales force, as well as through distributors, resellers and systems
integrators. We currently have approximately 9,500 customers, including approximately 1,400 financial institutions, in more than 100 countries. Representative customers of our products include HSBC, Rabobank Nederland, BNP-Paribas Fortis, Wachovia
and Blizzard Entertainment. The number of new accounts added in each of the past three fiscal years is as follows:

Although management considers the number of new customers as an indicator of the momentum of
our business and effectiveness of our distribution channel, the number of new customers is not indicative of future revenue.

Our
Background

Our predecessor company, VASCO Corp., entered the data security business in 1991 through the acquisition of a
controlling interest in ThumbScan, Inc., which we renamed VASCO Corporation in 1993. In 1996, we began an expansion of our computer security business by acquiring Lintel Security NV/SA, a Belgian corporation, which included assets associated with
the development of security tokens and security technologies for personal computers and computer networks. In addition, in 1996, we acquired 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.

On March 11, 1998, we completed a
registered exchange offer with the holders of the outstanding securities of VASCO Corp. Since the exchange offer, we have engaged in seven acquisitions and one disposition.

In December 2006, we opened our international headquarters in Zurich, Switzerland. In August 2007, we established a wholly-owned sales
subsidiary in Brazil, and in December 2007, we established a wholly-owned sales subsidiary in Japan. In 2008, we established a wholly-owned sales subsidiary in Mumbai, India and added a sales presence in Bahrain.

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 that will continue to allow them to expand access to data and financial assets while maintaining network security.

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 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 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 will benefit from the implementation of improved security measures that accurately identify users and reliably encrypt data transmissions over the Internet. To
minimize losses due to misappropriation of credit card information, many banks in European countries have issued smart cards (credit cards with a micro-chip) that are compliant with the EMV standard.

Several governments worldwide have recognized the risk associated with using fixed passwords for Internet applications and have issued
specific rules requiring two-factor authentication for online banking security. We expect that trend to continue and that governments in many countries will prepare similar guidance and/or rules in order to protect their citizens online
assets.

##### Table of Contents

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 that keeps track of a users activities after access has been granted.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Administration and Management Tools: Software that 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. Many companies, however, only implement a patchwork of these components, which could result in their security systems being compromised.

Our Solution

We have found
that, 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 within diverse enterprise environments, existing customer applications and the security infrastructure;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 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 their integration effort with, and disruption of, existing legacy applications and the security
infrastructure. 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 on-line business initiatives,
speed and ease of security implementation has become crucial to an organizations success.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We design our products and services to have a more attractive total cost of 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.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

As a result of this approach, we believe that we are a leading provider of strong software
and hardware authentication security that can be combined with electronic and digital signature (e-signature) solutions for all types of on-line, risk-based transactions.

Our Strategy

We believe that we have one of the most complete lines of
security products and services for strong user authentication and e-signatures available in the market today. We also believe that we can demonstrate to an increasing number of distributors, resellers and systems integrators that they can more
effectively differentiate themselves in their marketplaces and increase the value of their products by incorporating our security products into their own products. On a broad basis, our strategy is to:



| |  |  | Continue our full-option, end-to-end authentication strategy by offering the financial services sector the full array of authentication
products and services;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expand our penetration in new markets (all-terrain strategy) by taking the products offered in the financial services sector to other
markets including, but not limited to, business enterprises and other vertical markets that center around core applications that are similar to the way that the financial services market operates e-commerce applications and e-government
applications; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Strengthen our position in markets other than financial services by developing and offering application or market-specific authentication products and
services.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------

Increase Sales and Marketing Efforts.We plan to increase our investment in sales and
marketing by hiring new staff to strengthen our position in existing markets, increase our focus on new vertical application markets and increase our support for the indirect sales channel. We plan to increase the number of our marketing events,
such as banking summits, enterprise security and application security events. We also plan to open new offices in the worlds leading business hubs following a three-step strategy:



| |  |  | Gain a foothold in the countrys financial services market;
| | - |  | -----------------------------------------------------------



| |  |  | Hire local staff to reinforce our position in the financial services market; and
| | - |  | --------------------------------------------------------------------------------



| |  |  | Open an office and hire additional staff to expand our presence into the other application-specific markets. As part of our strategy for the other
application-specific markets, we plan to:
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | - |  | Develop a marketing and sales infrastructure, largely in the form of new resellers, distributors, and solution providers.
| | - |  | -------------------------------------------------------------------------------------------------------------------------

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:



| |  |  | Hiring more engineers to expand our product development capability;
| | - |  | -------------------------------------------------------------------



| |  |  | Building on our core software and hardware security expertise by continuing to expand our technology and services for use on different platforms, such
as mobile phones and personal digital assistants;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expanding our authentication services product offering;
| | - |  | -------------------------------------------------------



| |  |  | Acquiring complementary technologies or businesses; and
| | - |  | -------------------------------------------------------



| |  |  | Developing products for applications in new vertical markets.

Our Products

VACMAN Product Line

The VACMAN product line incorporates a range of strong
authentication utilities and solutions designed to allow organizations to add DIGIPASS strong authentication into their existing networks and applications.

In order to provide the greatest flexibility, without compromising on functionality or security, VACMAN solutions are designed to integrate with most popular hardware and software. Once integrated, the
VACMAN components become largely transparent to the users, minimizing rollout and support issues.

VACMAN Controller

VACMAN Controller is the backbone of VASCOs product strategy towards the banking and e-commerce markets.
VACMAN Controller encompasses all four authentication technologies (passwords, dynamic password technologies, certificates and biometrics) and allows our customers to use any combination of those technologies simultaneously. VACMAN Controller is
natively embedded in or compatible with the solutions of over 100 VASCO solution partners.

Designed by
specialists in system entry security, VACMAN Controller makes it easy to administer a high level of access control and allows our customers to match the level of authentication security used with their perceived risk for each user of
their application. Our customer simply adds a field to his or her existing user database, describing the authentication technology used and, if applicable, the unique DIGIPASS token assigned to the end user of their application. VACMAN Controller
takes it from there, automatically authenticating the logon request using the security sequence the user specifies, whether its a one-time password using either response-only or a challenge/response authentication scheme or an electronic
signature.

VACMAN Controller allows the user the freedom to provide secure remote access to virtually any type
of application. VACMAN Controller is a library requiring only a few days to implement in most systems and supports all DIGIPASS functionality. Once linked to an application, VACMAN Controller automatically handles login requests from any users
authorized to have a DIGIPASS.

VACMAN Middleware

For organizations of all sizes that need to authenticate remote users for access to enterprise networks and their
applications, VACMAN Middleware is a software suite used to verify authentication requests and to centrally administer user authentication policies. Unlike other authentication solutions, VACMAN Middlewaretogether with VASCOs DIGIPASS
familyprovides affordable strong authentication and secure access to web applications, business applications and VPN.

VACMAN Middleware in combination with DIGIPASS authenticators eliminates the weakest link in any security structure, the use of static passwords. Its a turnkey solution that can be up and running in
minutes, not hours or weeks.

The main authentication tool in a VACMAN Middleware enabled
infrastructure remains the Active Directory service. The storage of the DIGIPASS related data is linked with the users in the Active Directory. As a result, a scalable approach is achieved and an optimal support is provided for multiple domains and
delegated administration. VACMAN Middleware supports Open DataBase Connectivity (ODBC) compliant databases, such as Oracle 9iTM, Microsoft® SQL server 2000 and 2005, IBM DB2 8.1, Sybase® Adaptive Server Anywhere 9.0 and PostgreSQL 8.0 and 8.1. VACMAN Middleware is delivered with PostgreSQL update database release versions.

##### Table of Contents

The audit console monitors incoming and outgoing RADIUS (Remote
Authentication Dial-in User Service) and web traffic (or any other events) on the VACMAN Middleware server. The audit console presents all the statistical information needed to manage remote access environments including:



| |  |  | connection period;
| | - |  | ------------------



| |  |  | number of information messages;
| | - |  | -------------------------------



| |  |  | warnings; and
| | - |  | -------------



| |  |  | errors and fatal errors.
| | - |  | ------------------------

VACMAN Middleware uses a non-intrusive method of enabling DIGIPASS authentication, eliminating hardware and software conflicts; VACMAN Middleware is placed between the Network Access Server and the
existing RADIUS server  without affecting the performance of either.

IDENTIKEY Server 3.1

IDENTIKEY Server 3.1 is full-function authentication server software for network and application security offering one-time passwords and
e-signature capability. IDENTIKEY is based on VASCOs core VACMAN technology and offers an authentication solution for several markets including Software as a Service (SaaS), e-gaming, online gambling, healthcare, automotive, e-banking and VPN
access.

aXs GUARD Product Line

There are two types of aXs GUARD appliances: aXs GUARD Identifier and aXs GUARD Gatekeeper.

aXs GUARD Identifier

aXs GUARD Identifier is a
standalone authentication solution that offers strong two-factor authentication for remote access to a corporate network or to web-based in-house business applications. It comes in a standard 19 inch rack with a mountable slim fit
design. The appliance verifies DIGIPASS/IDENTIKEY authentication requests from RADIUS clients and web filters and can easily be integrated with any authentication server. It features a web based administration interface as well as an auditing and
reporting console.

aXs GUARD Gatekeeper

aXs GUARD Gatekeeper consists of a range of dedicated appliances that brings strong user authentication and secure
Internet communications to the enterprise through a choice of multiple software modules. aXs GUARD Gatekeeper integrates DIGIPASS to provide secure two factor user authentication. It is a standalone modular communications solution providing
intrusion, website and virus protection; remote connection through VPNs and a reporting and monitoring console, among other things.

DIGIPASS Product Line

Our DIGIPASS product line, which exists as a family of software and hardware client
authentication products and services, provides a flexible and affordable means of authenticating users to any network, including the Internet.

Security can be broken into three factors:



| |  |  | What the user has (the DIGIPASS itself, in either hardware or software version);
| | - |  | --------------------------------------------------------------------------------



| |  |  | What the user knows (the PIN code to activate the DIGIPASS); and
| | - |  | ----------------------------------------------------------------



| |  |  | Who the user is (biometrics).
| | - |  | -----------------------------



10

##### Table of Contents

The DIGIPASS family is currently based on the first two factors. Using the DIGIPASS system,
in order to enter a remote system or to digitally sign data, the user needs the:



| |  |  | Software and hardware client authentication device (DIGIPASS) itself; if he or she does not physically have the device, he or she will not be able to
log on to the system; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PIN code for the DIGIPASS; if the user does not know the appropriate code, he or she will not be able to use the applications stored inside.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------

Both factors help ensure that a natural person is authenticating (or signing), instead of a computer or
another device. These factors also enable very high portability for security anytime and anywhere.

DIGIPASSES calculate
dynamic signatures and passwords, also known as one-time passwords, to authenticate users on a computer network and for a variety of other applications. There are over 50 models of the DIGIPASS, each of which has its own distinct characteristics
depending on the platform that it uses and the functions it performs. 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 the integrity of the contents of such transactions.

DIGIPASS technology is designed to operate on non-VASCO platforms such as a desktop PC or laptop. DIGIPASS technology is also
available for personal digital assistants (PDA), mobile phones and smart cards. For users of mobile phones, the virtual DIGIPASS generates one-time passwords that are sent to the mobile telephone user by SMS (Short Messaging System).

Other technologies such as paper based authentication (TAN lists) and PKI-enabled products are successfully created in the DIGIPASS family,
always based on the same back-end VACMAN core technology.

DIGIPASS technology also combines the benefits of traditional
password authenticators (authentication and digital signatures) with smart card readers. Together, they bring portability to smart cards and allow secure time-based algorithms.

The DIGIPASS technology is also available in a web browser based version. DIGIPASS for Web is the ideal product to replace a password-based
security or paper-based authentication system with a security system using strong authentication, to achieve a higher security level. DIGIPASS for Web supports user authentication, transaction signing and document signing. No software installation
is required on the end-users PC.

We believe a VASCO-secured system has the features needed to secure both todays
and tomorrows IT resources.

products and services on one unique platform. This allows us to go to market with a very flexible, full option authentication offering. Our customers can choose which type of client authentication product they offer to their different
end user segments.

Currently, our products are used in a wide variety of applications, the largest of which is banking.
Banking applications include:



| |  |  | 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, wireless phones and other communication devices such as personal digital assistants.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Another
significant application for our products is to secure access to corporate networks for home-based, traveling and other remote users. DIGIPASSES are increasingly being used in a variety of e-commerce applications where the user is part of a
pre-defined user group. Finally, VASCOs product lines are breaking through in a number of new, end-user-facing verticals, such as e-gaming. 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.

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 U.S. and in other countries, which cover multiple aspects of our technology. These patents expire between 2010 and 2022. We do not believe that the expiration of
patents in 2010 will affect business, profitability or increase competition. In addition to the issued patents, we also have several patents pending in the U.S., Europe and other countries. The majority of our issued and pending patents cover our
DIGIPASS family. 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.

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 a team of full-time engineers and, from time to time, also engage independent engineering firms to conduct non-strategic research and
development efforts on our behalf. We recorded $11.6, $11.6 and $9.4 million for fiscal years ended December 31, 2009, 2008, and 2007, respectively, on company-sponsored research and development.

Production

Our security
hardware DIGIPASSES are manufactured by third party manufacturers pursuant to purchase orders that we issue. Our hardware DIGIPASSES are made primarily from commercially available electronic components that are purchased globally. Our software
products, including software versions of our DIGIPASSES are produced in-house.

Hardware DIGIPASSES utilize commercially
available programmable microprocessors, or chips. We use a limited number of microprocessors, made by Samsung, for the various hardware products we produce. The Samsung microprocessors are purchased from Samsung Semiconductor in Germany. The
microprocessors are the only components of our security authenticators that are not commodity items readily available on the open market.

Orders of microprocessors generally require a lead-time of 12-16 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 make appropriate arrangements with our suppliers.

We purchase the microprocessors and arrange for shipment to third parties for assembly and testing in accordance with our design
specifications. Our DIGIPASS products are assembled by one of three independent companies with headquarters in Hong Kong and production facilities in China. Purchases from these companies are made on a volume purchase order basis. These companies
commit to very high production standards, and as a result, they also have major production contracts with Japanese hi-tech companies. 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.

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. Our main competitor is RSA Security, a subsidiary of EMC Corporation. Additional competitors are ActivIdentity, Gemalto, Todos Data

##### Table of Contents

Systems and Kobil Systems. There are many other companies such as SafeNet, Aladdin Knowledge Systems, and Entrust, that offer authentication 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, customer base, distribution channels and the total cost of ownership of the authentication solution. 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.

Some 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. It is possible that new competitors or alliances may emerge and rapidly acquire significant
market share. Accordingly, we have forged, and will continue to forge, our own partnerships to offer a broader range of products and capabilities to the market.

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.

Sales and Marketing

Our security solutions are sold through our direct sales force, as well as through 71 distributors, their reseller networks and systems integrators. A sales staff of 70 coordinates our sales activity through both our sales channels and our
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 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 that explain how we believe our security
products can add value or otherwise be beneficial.

Customers and Markets

Customers for our products include some of the worlds most recognized names: HSBC, Rabobank Nederland, BNP-Paribas Fortis, Wachovia,
and Blizzard Entertainment. In 2009, we announced numerous new customers around the world including, but not limited to, Caixa Galicia (Spain), Landesbank Baden-Württemberg Bank (Germany), Square Enix Co. (Japan), and HSBC Paraguay.

Our top 10 customers contributed 34%, 44% and 45%, in 2009, 2008 and 2007, respectively, of
total worldwide revenue. There was no single customer that accounted for more than 10% of our revenue in 2009, 2008 or in 2007.

A significant portion of our sales is denominated in foreign currencies and changes in exchange rates could impact results of operations. To minimize exposure to risks associated with fluctuations in currency exchange rates, we attempt to
denominate an amount of billings in a currency such that it would provide a hedge against operating expenses being incurred in that currency. For additional information regarding how currency fluctuations can affect our business, please refer to
Managements Discussion and Analysis of Financial Condition and Results of Operations and Quantitative and Qualitative Disclosures about Market Risk.

We also experience seasonality in our business. Historically, these seasonal trends are most notable in the summer months, particularly in
Europe, when many businesses defer purchase decisions; however, given the relatively small size of our business, the timing of any one or more large orders may temper or offset this seasonality.

We organize our sales group and report our results in two vertical markets:



| |  |  | Banking and Financial Institutions: Our traditional stronghold where we believe that there are substantial opportunities for future growth.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Enterprise and Application Security: Our second market that has grown into a robust source of revenue and includes:
| | - |  | -------------------------------------------------------------------------------------------------------------------



| | - |  | Various corporations for network and remote access: We have enjoyed growing success in this market and have developed new products that we believe will
allow us to compete more effectively for both SME (small and medium enterprises) as well as large corporations.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - |  | Other application-specific markets: Our products are being used in more than 50 different applications and we believe that we will be able to identify
and leverage our knowledge with those applications to increase our penetration in the more promising markets.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - |  | E-commerce: Both business-to-business and business-to-consumer e-commerce are becoming ever more important for us.
| | - |  | ------------------------------------------------------------------------------------------------------------------



| | - |  | E-government: Our revenue in this market is still small, but we are ready to take advantage of the markets evolution.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

Our channel partners are critical to our success in the Enterprise and Application Security markets. We
serve this market exclusively via our two-tier indirect sales channel. We train employees of our resellers and distributors on-site and in our offices. In addition, we have developed online video training software that allows us to train people
worldwide, resulting in cost and time benefits.

We invest in and support our channel with marketing and public relations
actions. Distributors and resellers get the tools they need to be successful, such as campaigns, case studies, marketing funds and more. We expect our Enterprise and Application Security market to become even more successful in the future.

Backlog

Our
backlog at December 31, 2009 was approximately $19.9 million compared to $29.1 million at December 31, 2008. We anticipate that substantially all of the backlog at the end of 2009 will be shipped in 2010. We do not believe that the
specific amount of backlog at any point in time is indicative of the trends in our markets or the expected results of our business. Given the relatively small size of our business and the large size of potential orders, the backlog number can change
significantly with the receipt of a new order or modification of an existing order, for example, shipment timing.

Financial Information Relating to Foreign and Domestic Operations

For financial information regarding VASCO, see our Consolidated Financial Statements and the related Notes, which are included in this Annual
Report on Form 10-K. We have a single reportable segment for all our products and operations. See Note 12 in the Notes to Consolidated Financial Statements for a breakdown of revenue and long-lived assets between U.S. and foreign operations.

Employees

As of December 31, 2009, we had 294 full time employees. Of these, 27 were located in the U.S., 222 in EMEA (Europe, the Middle East and Africa), 15 in the Asia Pacific Rim countries and 30 in other countries, including Australia,
Latin America, India and Central Asia. Of the total, 156 were involved in sales, marketing and customer support, 92 in research and development and 46 in general and administration.

Item 1A -Risk Factors

RISK FACTORS

You should carefully consider the following risk factors,which we consider the
most significant, as well as other information contained in this Annual Report on Form 10-K. In addition, there are a number of less significant and other general risk factors that could affect our future results. If any of the events described in
the risk factors were to occur, our business, financial condition or operating results could be materially and adversely affected. We have grouped our Risk Factors under captions that we believe describe various categories of potential risk. For the
readers convenience, we have not duplicated risk factors that could be considered to be included in more than one category.

Risks Related to Our Business

The worldwide recession and credit crisis have impacted our business.

The companys business was negatively affected in 2009 by a recession in many of the countries in which we do business and a credit
crisis impacting banks in some of our markets. The tightening of credit in financial markets and the general economic downturn may have adversely affected the ability of our customers, suppliers, outsource manufacturers and channel partners (e.g.
distributors and resellers) to obtain the financing they need to make purchases from us or to perform their obligations under agreements with us or even to continue their operations. The credit tightening and decreased cash availability could also
result in (a) an increase in cancellation of orders for our products and services and/or a decrease in demand for our products and services, (b) an inability to collect our accounts receivable on a timely basis, which may result in
additional reserves for uncollectible accounts receivable and (c) in the event of the contraction of our sales, dated inventory, which could result in a need for additional obsolescence reserves, each of which, individually or in aggregate,
could cause our actual results to differ materially from our current expectations.

We are unable to predict the duration and
the severity of the economic downturn and disruption in financial markets or their effect on our business and results of operations, but the consequences may be materially adverse.

The current worldwide economic conditions may affect our liquidity and capital resources.

While we believe that our financial resources and current borrowing arrangements are adequate to meet our operating needs, we anticipate that the difficult current economic conditions that exist on a
worldwide basis today may require us to modify our business plans. In the current economic environment there is a risk that customers may delay their orders until the economic conditions stabilize further or improve. If a significant



16



---

##### Table of Contents

number of orders are delayed for an indefinite period of time, our revenue and cash receipts may not be sufficient to meet the operating needs of the business. If this is the case, we may need to
borrow against our credit line (if it is still available to us), significantly reduce our workforce, sell certain of our assets, enter into strategic relationships or business combinations, discontinue some or all of our operations, or take other
similar restructuring actions. While we expect that these actions would result in a reduction of recurring costs, they also may result in a reduction of recurring revenue and cash receipts. It is also likely that we would incur substantial
non-recurring costs to implement one or more of these restructuring actions.

We have a long operating history, but only a small
accumulated profit.

Although we have reported net income of $11.9 million, $24.3 million and $20.1 million for the years
ended December 31, 2009, 2008, and 2007 , respectively, our retained earnings was only $36.7 million at December 31, 2009. Over our eighteen-year operating history, we have operated at a loss for many of those years. In the current
uncertain economic environment, it may be difficult for us to sustain our recent levels of profitability.

We derive revenue from a limited
number of products and do not have a broadly-diversified product base.

Substantially all of our revenue is derived from
the sale of authentication products. We also anticipate that a substantial portion of our future revenue, if any, will also be derived from these products. If the sale of these products is impeded for any reason and we have not diversified our
product offerings, our business and results of operations would be negatively impacted.

The sales cycle for our products and technology is
long, and we may incur substantial expenses for sales that do not occur when anticipated.

The sales cycle for our
products, which is the period of time between the identification of a potential customer and completion of the sale, is typically lengthy and subject to a number of significant risks over which we have little control. If revenue falls significantly
below anticipated levels, our business would be seriously harmed.

A typical sales cycle in the Banking market is often six
months or more. Larger Banking transactions may take up to 18 months or more. Purchasing decisions for our products and systems may be subject to delays due to many factors that are not within our control, such as:



| |  |  | The time required for a prospective customer to recognize the need for our products;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | The significant expense of many data security products and network systems;
| | - |  | ---------------------------------------------------------------------------



| |  |  | Customers internal budgeting processes; and
| | - |  | --------------------------------------------



| |  |  | Internal procedures customers may require for the approval of large purchases.
| | - |  | ------------------------------------------------------------------------------

As our operating expenses are based on anticipated revenue levels, a small fluctuation in the timing of sales can cause our operating results
to vary significantly between periods.

We have a great dependence on a limited number of suppliers and the loss of their manufacturing
capability could materially impact our operations.

In the event that the supply of components or finished products is
interrupted or relations with any of our principal vendors is terminated, there could be a considerable delay in finding suitable replacement sources to manufacture our products at the same cost or at all. The majority of our products are
manufactured by four independent vendors, one headquartered in Europe and the other three in Hong Kong. Our hardware DIGIPASSES are assembled at facilities in mainland China. The importation of these products from China exposes us to the possibility
of product supply disruption and increased costs in the event of changes in the policies of the Chinese government, political unrest or unstable economic conditions in China or developments in the United States that are adverse to trade, including
enactment of protectionist legislation.

##### Table of Contents

We have a significant dependence on major customers and losing any of these customers could result in a
significant loss in revenue.

If we dont find other customers who generate significant future revenue, the unforeseen
loss of one or more of our major customers, or the inability to maintain reasonable profit margins on sales to any of these customers, would have a material adverse effect on our results of operations and financial condition.

Our customers have the ability to reschedule their deliveries.

Prior to 2009, a major portion of our business was scheduled by our customers under purchase orders (POs) which called for multiple shipments over the course of 12 months. Typically, these were firm
orders with specific requests for shipments on specified dates. Historically, a customer may have requested that a shipment be accelerated and delivered earlier than scheduled or, conversely, delayed and delivered later than originally scheduled, or
in rare cases, cancelled. In 2009, we experienced instances in which customers delayed delivery shipments or placed smaller orders covering shorter periods of time. While we expect our customers to return to order patterns more similar to their
historical patterns, they may continue to delay shipments or order small quantities covering shorter periods of time. If our customers continue ordering on a basis consistent with 2009, each quarters results may vary substantially based on
orders delivered in that quarter.

Our success depends on establishing and maintaining strategic relationships with other companies to
develop, market and distribute our technology and products and, in some cases, to incorporate our technology into their products.

Part of our business strategy is to enter into strategic alliances and other cooperative arrangements with other companies in our industry. We currently are involved in cooperative efforts with respect to the incorporation of our products
into products of others, research and development efforts, marketing efforts and reseller arrangements. None of these relationships are exclusive, and some of our strategic partners also have cooperative relationships with certain of our
competitors. If we are unable to enter cooperative arrangements in the future or if we lose any of our current strategic or cooperative relationships, our business could be harmed. We do not control the time and resources devoted to such activities
by parties with whom we have relationships. In addition, we may not have the resources available to satisfy our commitments, which may adversely affect these relationships. These relationships may not continue, may not be commercially successful, or
may require our expenditure of significant financial, personnel and administrative resources from time to time. Further, certain of our products and services compete with the products and services of our strategic partners.

We may not be able to maintain effective product distribution channels, which could result in decreased revenue.

We rely on both our direct sales force and an indirect channel distribution strategy for the sale and marketing of our products. We may be
unable to attract distributors, resellers and integrators, as planned, that can market our products effectively and provide timely and cost-effective customer support and service. There is also a risk that some or all of our distributors, resellers
or integrators may be acquired, may change their business models or may go out of business, any of which could have an adverse effect on our business. Further, our distributors, integrators and resellers may carry competing lines of products. The
loss of important sales personnel, distributors, integrators or resellers could adversely affect us.

We depend on our key personnel for
the success of our business and the loss of one or more of our key personnel could have an adverse effect on our ability to manage our business or could be negatively perceived in the capital markets.

Our success and our ability to manage our business depend, in large part, upon the efforts and continued service of our senior management
team. The loss of one or more of our key personnel could have a material adverse effect on our business and operations. It could be difficult for us to find replacements for our key personnel, as competition for such personnel is intense. Further,
such a loss could be negatively perceived in the capital markets, which could reduce the market value of our securities.

##### Table of Contents

If we fail to continue to attract and retain qualified personnel, our business may be harmed.

Our future success depends upon our ability to continue to attract and retain highly qualified scientific, technical,
sales and managerial personnel. Competition for such personnel is intense and there can be no assurance that we can attract other highly qualified personnel in the future. If we cannot retain or are unable to hire such key personnel, our business,
financial condition and results of operations could be significantly adversely affected.

Changes in our effective tax rate may have an
adverse effect on our results of operations.

Our future effective tax rates may be adversely affected by a number of
factors including the distribution of income among the various countries in which we operate, changes in the valuation of our deferred tax assets, increases in expenses not deductible for tax purposes, including the impairment of goodwill in
connection with acquisitions, changes in share-based compensation expense, and changes in tax laws or the interpretation of such tax laws and changes in generally accepted accounting principles. Any significant increase in our future effective tax
rates could adversely impact net income for future periods.

Our worldwide income tax provisions and other tax accruals may be insufficient
if any taxing authorities assume taxing positions that are contrary to our positions.

Significant judgment is required in
determining our provision for income taxes and other taxes such as sales and VAT taxes. There are many transactions for which the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of intercompany agreements to
purchase intellectual properties, allocate revenue and allocate costs, each of which could ultimately result in changes once the arrangements are reviewed by taxing authorities. Although we believe that our approach to determining the amount of such
arrangements is reasonable, we can not be certain that the final tax authority review of these matters will not differ materially from what is reflected in our historical income tax provisions and other tax accruals. Such differences could have a
material effect on our income tax provisions or benefits, or other tax accruals, in the period in which such determination is made, and consequently, on our results of operations for such period.

Any acquisitions we make could disrupt our business and harm our financial condition.

We may make investments in complementary companies, products or technologies. Should we do so, our failure to successfully manage future
acquisitions could seriously harm our operating results. In the event of any future purchases, we will face additional financial and operational risks, including:



| |  |  | Difficulty in assimilating the operations, technology and personnel of acquired companies;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Disruption in our business because of the allocation of resources to consummate these transactions and the diversion of managements attention
from our existing business;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Difficulty in retaining key technical and managerial personnel from acquired companies;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | Dilution of our stockholders, if we issue equity to fund these transactions;
| | - |  | ----------------------------------------------------------------------------



| |  |  | Assumption of operating losses, increased expenses and liabilities; and
| | - |  | -----------------------------------------------------------------------



| |  |  | Our relationships with existing employees, customers and business partners may be weakened or terminated as a result of these transactions.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------

Reported revenue may fluctuate widely due to the interpretation or application of accounting rules.

Our sales arrangements often include multiple elements, including hardware, software and maintenance. The accounting rules for such
arrangements are complex and subject to change from time to time. Small changes in circumstances could cause wide deviations in the timing of reported revenue.

##### Table of Contents

Indemnity provisions in various agreements potentially expose us to substantial liability for
intellectual property infringement and other losses.

Our agreements with customers and channel partners include
indemnification provisions, under which we agree to indemnify them for losses suffered or incurred as a result of claims of intellectual property infringement and, in some cases, for damages caused by us to property or persons. Large indemnity
payments could harm our business, operating results and financial condition.

Risks Related to the Market

We face significant competition and if we lose or fail to gain market share our financial results will suffer.

The market for computer and network security products is highly competitive. Our competitors include organizations that provide computer and
network security products based upon approaches similar to and different from those that we employ, such as RSA Security (a subsidiary of EMC Corporation), Aladdin Knowledge Systems, SafeNet, ActivIdentity, Gemalto, Todos Data Systems and Kobil
Systems. Many of our competitors have significantly greater financial, marketing, technical and other competitive resources than we do. As a result, our competitors may be able to adapt more quickly to new or emerging technologies and changes in
customer requirements, or to devote greater resources to the promotion and sale of their products.

A decrease of average selling prices
for our products and services could adversely affect our business.

The average selling prices for our solution offerings
may decline as a result of competitive pricing pressures or a change in our mix of products, software and services. In addition, competition continues to increase in the market segments in which we participate and we expect competition to further
increase in the future, thereby leading to increased pricing pressures. Furthermore, we anticipate that the average selling prices and gross profits for our products will decrease over product life cycles. To sell our products and services at higher
prices, we must continue to develop and introduce new products and services that incorporate new technologies or increased functionality. If we experience pricing pressures or fail to develop new products, our revenue and gross margins could
decline, which could harm our business, financial condition and results of operations.

We may need additional capital in the future and
our failure to obtain capital would interfere with our growth strategy.

Our ability to obtain financing will depend on a
number of factors, including market conditions, our operating performance and investor interest. These factors may make the timing, amount, terms and conditions of any financing unattractive. They may also result in our incurring additional
indebtedness or accepting stockholder dilution. If adequate funds are not available or are not available on acceptable terms, we may have to forego strategic acquisitions or investments, defer our product development activities, or delay the
introduction of new products. Despite our strong cash position, we have a credit line in place for up to five million Euros or the equivalent in U.S. Dollars or Swiss Francs. This line of credit, however, can be terminated with 14 days advance
notice by either party in their sole discretion.

We experience variations in quarterly operating results and sales are subject to
seasonality, both of which may result in a volatile stock price.

In the future, as in the past, our quarterly operating
results may vary significantly, resulting in a volatile stock price. Factors affecting our operating results include:



| |  |  | The level of competition;
| | - |  | -------------------------



| |  |  | The size, timing, cancellation or rescheduling of significant orders;
| | - |  | ---------------------------------------------------------------------



| |  |  | New product announcements or introductions by competitors;
| | - |  | ----------------------------------------------------------



| |  |  | Technological changes in the market for data security products including the adoption of new technologies and standards;

We also experience seasonality in all markets. These seasonal trends are most notable in the summer months, particularly in Europe, when
many businesses defer purchase decisions.

Our stock price may be volatile for reasons other than variations in our quarterly operating
results.

The market price of our common stock may fluctuate significantly in response to factors, some of which are beyond
our control, including the following:



| |  |  | Actual or anticipated fluctuations in our quarterly or annual operating results;
| | - |  | --------------------------------------------------------------------------------



| |  |  | Differences between actual operating results and results estimated by analysts that follow our stock and provide estimates of our results to the
market;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Differences between guidance relative to financial results, if given, and actual results;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Changes in market valuations of other technology companies;
| | - |  | -----------------------------------------------------------



| |  |  | Announcements by us or our competitors of significant technical innovations, contracts, acquisitions, strategic partnerships, joint ventures or capital
commitments;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Additions or departures of key personnel;
| | - |  | -----------------------------------------



| |  |  | Future sales of common stock;
| | - |  | -----------------------------



| |  |  | Trading volume fluctuations; and
| | - |  | --------------------------------



| |  |  | Reactions by investors to the current turmoil in the world economy and financial markets.
| | - |  | -----------------------------------------------------------------------------------------

A small group of persons control a substantial amount of our common stock and could delay or prevent a change of control.

Our Board of Directors, our officers and their immediate families and related entities beneficially own approximately 28%, with Mr. T.
Kendall Hunt beneficially owning approximately 25%, of the outstanding shares of our common stock. As the Chairman of the Board of Directors, Chief Executive Officer and our largest stockholder, Mr. Hunt may exercise substantial control over
our future direction and operation and such concentration of control may have the effect of discouraging, delaying or preventing a change in control and may also have an adverse effect on the market price of our common stock.

Certain provisions of our charter and of Delaware law make a takeover of our company more difficult.

Our corporate charter and Delaware law contain provisions, such as a class of authorized but unissued preferred stock which may be issued by
our board without stockholder approval that might enable our management to resist a takeover of our company. Delaware law also limits business combinations with interested stockholders. These provisions might discourage, delay or prevent a change in
control or a change in our management. These provisions could also discourage proxy contests, and make it more difficult for you and other stockholders to elect directors and take other corporate actions. The existence of these provisions could
limit the price that investors might be willing to pay in the future for shares of our common stock.

Future issuances of blank check preferred stock may reduce voting power of common stock and may have
anti-takeover effects that could prevent a change in control.

Our corporate charter authorizes the issuance of up to
500,000 shares of preferred stock with such designations, rights, powers and preferences as may be determined from time to time by our Board of Directors, including such dividend, liquidation, conversion, voting or other rights, powers and
preferences as may be determined from time to time by the Board of Directors without further stockholder approval. The issuance of preferred stock could adversely affect the voting power or other rights of the holders of common stock. In addition,
the authorized shares of preferred stock and common stock could be utilized, under certain circumstances, as a method of discouraging, delaying or preventing a change in control.

Risks Related to Technology and Intellectual Property

Technological changes occur rapidly in our industry and our development of new products is critical to maintain our revenue.

The introduction by our competitors of products embodying new technologies and the emergence of new industry standards could render our existing products obsolete and unmarketable. Our future revenue
growth and operating profit will depend in part upon our ability to enhance our current products and develop innovative products to distinguish ourselves from the competition and to meet customers changing needs in the data security industry.
We cannot assure you that security-related product developments and technology innovations by others will not adversely affect our competitive position or that we will be able to successfully anticipate or adapt to changing technology, industry
standards or customer requirements on a timely basis.

Our products contain third-party, open-source software and failure to comply with
the terms of the underlying open-source software licenses could restrict our ability to sell our products or otherwise result in claims of infringement.

Our products are distributed with software programs licensed to us by third-party authors under open-source licenses, which may include the GNU General Public License (GPL), the GNU Lesser
Public License (LGPL), the BSD License and the Apache License. These open-source software programs include, without limitation, Linux, Apache, Openssl, IPTables, Tcpdump, Postfix, Cyrus, Perl, Squid and Snort. These third-party, open-source programs
are typically licensed to us for no fee and the underlying license agreements generally require us to make available to users the source code for such programs, as well as the source code for any modifications or derivative works we create based on
these third-party, open-source software programs.

We do not believe that we have created any modifications or derivative
works to, an extended version of, or works based on, any open-source software programs referenced above. We include instructions to users on how to obtain copies of the relevant open-source code and licenses.

We do not provide end users a copy of the source code to our proprietary software because we believe that the manner in which our
proprietary software is aligned or communicates with the relevant open-source programs does not create a modification, derivative work or extended version of, or a work based on, that open-source program requiring the distribution of our proprietary
source code.

Our ability to commercialize our products by incorporating third-party, open-source software may be restricted
because, among other reasons:



| |  |  | the terms of open-source license agreements are unclear and subject to varying interpretations, which could result in unforeseen obligations regarding
our proprietary products or claims of infringement;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | it may be difficult to determine the developers of open-source software and whether such licensed software infringes another partys intellectual
property rights;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



22



---

##### Table of Contents

| |  |  | competitors will have greater access to information by obtaining these open source products, which may help them develop competitive products; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | open-source software potentially increases customer support costs because licensees can modify the software and potentially introduce errors.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

We must continue to attract and retain highly skilled technical personnel for our research and development department.

The market for highly skilled technicians in Europe, Asia, Australia and the United States is highly competitive. If we
fail to attract, train, assimilate and retain qualified technical personnel for our research and development department, we will experience delays in introductions of new or modified products, loss of clients and market share and a reduction in
revenue.

We cannot be certain that our research and development activities will be successful.

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.

We depend significantly upon our proprietary technology and
intellectual property and the failure to protect our proprietary rights could require us to redesign our products or require us to enter into royalty or licensing agreements, any of which could reduce revenue and increase our operating costs.

We currently rely on a combination of patent, copyright and trademark laws, trade secrets, confidentiality agreements and
contractual provisions to protect our proprietary rights. We seek to protect our software, documentation and other written materials under trade secret and copyright laws, which afford only limited protection, and generally enter into
confidentiality and nondisclosure agreements with our employees and with key vendors and suppliers.

There has been
substantial litigation in the technology industry regarding intellectual property rights, and we may have to litigate to protect our proprietary technology.

We expect that companies in the computer and information security market will increasingly be subject to infringement claims as the number of products and competitors increases. Any such claims or
litigation may be time-consuming and costly, cause product shipment delays, require us to redesign our products or require us to enter into royalty or licensing agreements, any of which could reduce revenue and increase our operating costs.

Our patents may not provide us with competitive advantages.

We hold several patents in the United States and in other countries, which cover multiple aspects of our technology. The majority of our
patents cover the DIGIPASS product line. These patents expire between 2010 and 2022. In addition to the issued patents, we also have several patents pending in the United States, Europe and other countries. There can be no assurance that we will
continue to develop proprietary products or technologies that are patentable, that any issued patent will provide us with any competitive advantages or will not be challenged by third parties, or that patents of others will not hinder our
competitive advantage. 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.

We are subject to warranty and product liability risks.

A malfunction of or design defect in our products which results in a breach of a customers data security could result in tort or
warranty claims against us. We seek to reduce the risk of these losses by



23



---

##### Table of Contents

attempting to negotiate warranty disclaimers and liability limitation clauses in our sales agreements. However, these measures may ultimately prove ineffective in limiting our liability for
damages. We do not presently maintain product liability insurance for these types of claims.

In addition to any monetary
liability for the failure of our products, an actual or perceived breach of network or data security at one of our customers could adversely affect the markets perception of us and our products, and could have an adverse effect on our
reputation and the demand for our products. Similarly, an actual or perceived breach of network or data security within our own systems could damage our reputation and have an adverse effect on the demand for our products.

There is significant government regulation of technology exports and to the extent we cannot meet the requirements of the regulations we may be
prohibited from exporting some of our products, which could negatively impact our revenue.

Our international sales and
operations are subject to risks such as the imposition of government controls, new or changed export license requirements, restrictions on the export of critical technology, trade restrictions and changes in tariffs. If we become unable to obtain
foreign regulatory approvals on a timely basis our business in those countries would no longer exist and our revenue would decrease dramatically. Certain of our products are subject to export controls under U.S. law. The list of products and
countries for which export approval is required, and the regulatory policies with respect thereto may be revised from time to time and our inability to obtain required approvals under these regulations could materially and adversely affect our
ability to make international sales.

We employ cryptographic technology in our authentication products that uses complex mathematical
formulations to establish network security systems.

Many of our products are based on cryptographic technology. With
cryptographic technology, a user is given a key that is required to encrypt and decode messages. The security afforded by this technology depends on the integrity of a users key and in part on the application of algorithms, which are advanced
mathematical factoring equations. These codes may eventually be broken or become subject to government regulation regarding their use, which would render our technology and products less effective. The occurrence of any one of the following could
result in a decline in demand for our technology and products:



| |  |  | Any significant advance in techniques for attacking cryptographic systems, including the development of an easy factoring method or faster, more
powerful computers;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Publicity of the successful decoding of cryptographic messages or the misappropriation of keys; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | Increased government regulation limiting the use, scope or strength of cryptography.
| | - |  | ------------------------------------------------------------------------------------

Risks Related to International Operations

We face a number of risks associated with our international operations, any or all of which could result in a disruption in our business and a decrease in our revenue.

In 2009, approximately 93% of our revenue and approximately 83% of our operating expenses were generated/incurred outside of the U.S. In
2008, approximately 94% of our revenue and approximately 79% of our operating expenses were generated/incurred outside of the U.S. A severe economic decline in any of our major foreign markets could adversely affect our results of operations and
financial condition.

In addition to exposures to changes in the economic conditions of our major foreign markets, we are
subject to a number of risks any or all of which could result in a disruption in our business and a decrease in our revenue. These include:



| |  |  | Inconsistent regulations and unexpected changes in regulatory requirements;
| | - |  | ---------------------------------------------------------------------------



| |  |  | Export controls relating to our technology;
| | - |  | -------------------------------------------

We are
subject to foreign exchange risks, and improper management of that risk could result in large cash losses.

Because a
significant number of our principal customers are located outside the United States, we expect that international sales will continue to generate a significant portion of our total revenue. We are subject to foreign exchange risks because the
majority of our costs are denominated in U.S. Dollars, whereas a significant portion of the sales and expenses of our foreign operating subsidiaries are denominated in various foreign currencies. A decrease in the value of any of these foreign
currencies relative to the U.S. Dollar could affect the profitability in U.S. Dollars of our products sold in these markets. We do not currently hold forward exchange contracts to exchange foreign currencies for U.S. Dollars to offset currency
rate fluctuations.

We must comply with European governmental regulations setting environmental standards.

Our activities in Europe require that we comply with European Union Directives with respect to product quality assurance standards and
environmental standards. Directive 2002/95/ec of the European Parliament on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, known as the RoHS Directive, became effective on July 1, 2006. If we
fail to maintain compliance, we may be restricted from selling our products in the European Union and this could adversely affect our results of operations. European Directive 2002/96/EC on waste, electrical and electronic equipment, known as the
WEEE Directive, makes manufacturers of electrical and electronic equipment financially responsible for specified collection, recycling, treatment and disposal of past and future covered products. The WEEE Directive became effective on
August 13, 2005. We may incur financial responsibility for the collection, recycling, treatment or disposal of products covered under the WEEE Directive. Because the EU member states have not fully implemented the WEEE Directive, the nature and
extent of the costs to comply and fees or penalties associated with noncompliance are unknown at this time. Costs to comply with the WEEE Directive and similar future legislation, if applicable, may also include legal and regulatory costs and
insurance costs. We may also be required to take additional reserves for costs associated with compliance with these regulations.

We or
our suppliers may be impacted by new regulations related to climate change.

In addition to the European environmental
regulations noted above, we or our suppliers may become subject to new laws enacted with regards to climate change. In the event that new laws are enacted or current laws are modified in countries in which we or our suppliers operate, our flow of
product may be impacted and/or the costs of handling the potential waste associated with our products may increase dramatically, either of which could result in a significant negative impact on our ability to operate or operate profitably.

U.S. investors may have difficulties in making claims for any breach of their rights as holders of shares because some of our assets and
executives are not located in the United States.

Several of our executives and key employees are residents of foreign
countries, and a substantial portion of our assets and those of some of our executives and key employees are located in foreign countries. As



25

a result, it may not be possible for investors to effect service of process on those persons located in foreign countries, or to enforce judgments against some of our executives and key employees
based upon the securities or other laws of jurisdictions in those foreign countries.

Our business in countries with a history of
corruption and transactions with foreign governments increase the risks associated with our international activities.

As we operate and sell internationally, we are subject to the U.S. Foreign Corrupt Practices Act (FCPA), and other laws that prohibit improper payments or offers of payments to foreign governments and their officials and political
parties by U.S. and other business entities for the purpose of obtaining or retaining business. We have operations, deal with and make sales to governmental or quasi-governmental customers in countries known to experience corruption,
particularly certain countries in the Middle East, Africa, East Asia and South America, and further expansion of our international selling efforts may involve additional regions. Our activities in these countries create the risk of unauthorized
payments or offers of payments by one of our employees, consultants, sales agents or channel partners that could be in violation of various laws, including the FCPA, even though these parties are not always subject to our control. Violations of
the FCPA may result in severe criminal or civil sanctions, including suspension or debarment from U.S. government contracting, and we may be subject to other liabilities, which could negatively affect our business, operating results and
financial condition.

Cautionary
Note Regarding Forward-Looking Statements

This Annual Report on Form 10-K, including Managements Discussion and
Analysis of Financial Condition and Results of Operations and Quantitative and Qualitative Disclosures About Market Risk contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 and
Section 27A of the Securities Act of 1933 concerning, among other things, the prospects of, and developments and business strategies for, VASCO and our operations, including the development and marketing of certain new products and the
anticipated future growth in certain markets in which we currently market and sell our products or anticipate selling and marketing our products in the future. These forward-looking statements (1) are identified by use of terms and phrases such
as expect, believe, will, anticipate, emerging, intend, plan, could, may, estimate, should, objective and
goal and similar words and expressions, but such words and phrases are not the exclusive means of identifying them, and (2) are subject to risks and uncertainties and represent our present expectations or beliefs concerning future
events. VASCO cautions that the forward-looking statements are qualified by important factors that could cause actual results to differ materially from those in the forward-looking statements. These risks, uncertainties and other factors have been
described in greater detail in this Annual Report on Form 10-K and include, but are not limited to, (a) risks of general market conditions, including currency fluctuations and the unprecedented uncertainties resulting from the current turmoil
in world economic and financial markets, (b) risks inherent to the computer and network security industry, including rapidly changing technology, evolving industry standards, increasing numbers of patent infringement claims, changes in customer
requirements, price competitive bidding, and changing government regulations, and (c) risks specific to VASCO, including, demand for our products and services, competition from more established firms and others, pressures on price levels and
our historical dependence on relatively few products, certain suppliers and certain key customers. Thus, the results that we actually achieve may differ materially from any anticipated results included in, or implied by these statements.

General

The following
discussion is based upon our consolidated results of operations for the years ended December 31, 2009, 2008 and 2007 (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 Annual Report on Form 10-K.

We design, develop, market and
support open standards-based hardware and software security systems that manage and secure access to information assets. We also design, develop, market and support patented strong user authentication products and services for e-business and
e-commerce. Our products enable secure financial transactions to be made over private enterprise networks and public networks, such as the Internet. Our strong user authentication is delivered via our hardware and software DIGIPASS security products
(collectively DIGIPASSES), most of which incorporate an electronic signature capability, which further protects the integrity of electronic transactions and data transmissions. Some of our DIGIPASSES are compliant with the Europay MasterCard Visa
(EMV) standard and are compatible with MasterCards and VISAs Chip Authentication Program (CAP). Some of our DIGIPASS units comply with the Initiative for Open Authentication (OATH). As evidenced by our current customer base, our products
are purchased by companies and, depending on the business application, are distributed to either their employees or their customers. Those customers may be other businesses or, as an example in the case of Internet banking, our customer banks
corporate and retail customers.

Our target market is any business process that uses some form of electronic interface,
particularly the Internet, where the owner of that process is at risk if unauthorized users can gain access to its process and either

obtain proprietary information or execute transactions that are not authorized. Our products can not only increase the security associated with accessing the business process, thereby reducing
the losses from unauthorized access, but also, in many cases, can reduce the cost of the process itself by automating activities that were previously performed manually.

Industry Growth:We believe that, while there are no accurate measurements of the total industrys size, the industry growth rate is increasing and will continue to grow at a significant rate
into the foreseeable future. Growth is being driven by new government regulations, growing awareness of the impact of identity theft, and the growth in commerce that is transacted electronically. The issues driving the growth are global issues and
the rate of adoption in each country is a function of that countrys culture, the competitive position of businesses operating in those countries, the countrys overall economic conditions and the degree to which businesses and consumers
within the country use technology. While industry growth in 2009 was negatively impacted by the financial crisis in many countries, especially in relation to banks, and a recession in most countries, we expect that the industry will stabilize and
begin to grow again in 2010.

Economic Conditions:Our revenue may vary significantly with changes in the economic
conditions in the countries in which we currently sell products. With our current concentration of revenue in Europe and specifically in the banking/finance vertical market, significant changes in the economic outlook for the European banking market
may have a significant effect on our revenue. As a result of the difficult economy in 2009, our customers delayed the rollout of existing applications and deferred purchase decisions related to the implementation of our product in new applications.
In the Banking market, we saw an increased focus on short-term objectives while the banks internal structures were being realigned based on new ownership or new government rules. Also, we believe that many banks were postponing marketing
campaigns and related large-scale deployments of our products until a time when such marketing campaigns were expected to yield a higher return. For several consecutive quarters the banks placed smaller orders, which we believe was done to primarily
meet their short-term needs. We responded to the difficult economic conditions in 2009 by focusing our sales efforts on markets that we believed to have the most near-term opportunity and by implementing cost containment initiatives, which included
but were not limited to a hiring freeze. In the fourth quarter of 2009, however, we saw an increase in requests for information and proposals as well as an increase in orders. We believe that the increase in activity indicates that the worst of the
recession and credit crisis is past. With the apparent abatement of the difficult economic conditions in the fourth quarter of 2009 in many of the countries in which we operate, we plan to begin hiring staff to support new product development and
sales initiatives as well as hiring staff to mitigate risk and strengthen our position in existing markets. While these actions are expected to result in lower operating income as a percentage of revenue in 2010, we believe that these actions will
allow us to strengthen our overall market position and result in higher revenue in future years.

Currency
Fluctuations. In 2009, approximately 93% of our revenue and approximately 83% of our operating expenses were generated/incurred outside of the U.S. In 2008, approximately 94% of our revenue and approximately 79% of our operating expenses were
generated/incurred outside of the U.S. As a result, changes in currency exchange rates, especially the Euro to U.S. Dollar, can have a significant impact on revenue and expenses. To minimize the net impact of currency on operating earnings, we
attempt to denominate an amount of billings in a currency such that it would provide a hedge against the operating expenses being incurred in that currency. If our revenue in Europe continues as it is now or grows, however, we do not expect that we
will be able to balance fully the exposures of currency exchange rates on revenue and operating expenses. In periods in which the U.S. Dollar is weakening, we expect that our operating earnings will increase as a result of the change in
currency exchange rates. Conversely, in periods in which the U.S. Dollar is strengthening, we expect that our operating earnings will decrease as a result of the change in currency exchange rates.

In addition, in years prior to 2008, we also attempted to minimize transaction gains and losses by hedging our net U.S. Dollar net
asset exposure by borrowing U.S. Dollars in foreign countries such that assets denominated in U.S. Dollars were approximately equal to liabilities denominated in U.S. Dollars. With the growth in our cash balances, we discontinued the borrowing
process in 2007, but will reconsider reinstating the program if it appears that the benefit will exceed the cost.

##### Table of Contents

In 2009 compared to 2008, the U.S. Dollar strengthened approximately 6% against the
Euro and approximately 12% against the Australian Dollar. In 2008 compared to 2007, the U.S. Dollar weakened approximately 7% against the Euro and approximately 3% against the Australian Dollar. We estimate that the strengthening of the
U.S. Dollar in 2009 compared to 2008 resulted in a decrease in revenue of approximately $2,513 and a decrease in operating expenses of $3,100. We also estimate that the weakening of the U.S. Dollar in 2008 compared to 2007 resulted in an
increase in revenue of approximately $4,188 and an increase in operating expenses of approximately $3,176.

It should be
noted, however, that the U.S. Dollar weakened against both the Euro and Australian Dollar in the fourth quarter of 2009 and is expected to also be weaker in the first quarter of 2010 than it was in the first quarter of 2009. If the
U.S. Dollar continues to be weaker in 2010 than in the comparable period of 2009, we would expect that the differences in currency will have a positive effect on revenues that will only be partially offset by an increase in operating expense,
which would result in a increase of operating income.

The financial position and the results of operations of most of our
foreign subsidiaries, with the exception of our subsidiaries in Switzerland and Singapore, 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 generated other comprehensive income of $559 in 2009,
other comprehensive loss of $2,512 in 2008 and other comprehensive income of $4,887 in 2007. These amounts are included as a separate component of stockholders equity. The functional currency for both our subsidiaries in Switzerland and
Singapore is the U.S. Dollar.

Gains and losses resulting from foreign currency transactions are included in the consolidated
statements of operations as other non-operating income/expense. In 2009, we reported $835 of foreign exchange transaction gains compared to foreign exchange losses of $580 in 2008 and $906 in 2007.

Revenue

Revenue by
Geographic Regions: We classify our sales by customers location in four geographic regions: 1) EMEA, which includes Europe, the Middle East and Africa; 2) the United States, which for our purposes includes sales in Canada; 3) Asia Pacific
Rim; and 4) Other Countries, including Australia, Latin America and Central Asia. The breakdown of revenue in each of our major geographic areas was as follows:

2009 Compared to 2008

Total revenue in 2009 decreased $31,282 or 24% from 2008. The decrease in total revenue was primarily attributable to a
decline in products sold to the Banking market, both hardware and non-hardware, a decline in non-hardware products sold to the Enterprise and Application Security market and the strengthening of the U.S. dollar as compared to the Euro, as noted
above, partially offset by an increase in hardware products sold

to the Enterprise and Application Security market. Please see the discussion below under Revenue by Target Market for additional information regarding the changes in revenue from the
Banking market and the Enterprise and Application Security market.

Revenue generated in EMEA for the full-year 2009 was
$16,678 or 19% lower in 2009 than in 2008. The decrease was primarily attributable to factors noted above. We estimate that the change in currency rates reduced revenues in EMEA by $2,116 compared to 2008. Including the impact of currency, revenues
were approximately 25% lower in the Banking market and 11% higher in the Enterprise and Application Security market than in full-year 2008.

Revenue generated in United States for the full-year 2009 was $407 or 5% lower in 2009 than in 2008. Revenue was approximately 31% lower in the Banking market and 23% higher in the Enterprise and
Application Security markets than in full-year 2008. The U.S. market continues to defer the adoption of two factor authentication for retail internet banking applications. The results in the U.S. also reflect strong competition from our competitors,
especially in the Enterprise and Application Security market.

Revenue generated in Asia Pacific for the full-year 2009 was
$624 or 6% lower in 2009 than in 2008. Revenue was approximately 7% and 1% lower in the Banking and Enterprise and Application Security markets, respectively, than in full-year 2008. We believe that the region offers substantial opportunities for
growth in future years as our sales office in Japan, which was opened in 2007, matures and the two factor authentication market in China expands.

Revenue generated in other countries for the full-year 2009 was $13,573 or 53% lower in 2009 than in 2008. This decrease in other countries was primarily due to declines in South American Banking markets
where the initial deployments with large banking customers were completed in 2008. We estimate that the change in currency rates reduced revenues in other countries by $396 compared to 2008. We expect that revenue from other countries will be more
volatile than our other regions given the earlier stage of development of the authentication market in those countries. VASCO, however, plans to continue to invest in new markets based on our estimates of the markets demand for strong user
authentication.

Given the relatively small size of the revenue in regions other than EMEA, the results may vary substantially
year-to-year on both an absolute and on a percentage basis depending upon the timing of the receipt and delivery of a large new order or the completion of a large rollout. We believe that the variability in results will lessen as we develop a larger
base of Banking customers and further develop our distribution channel for the Enterprise and Application Security market.

2008 Compared to 2007

Total revenue in 2008 increased $12,997 or 11% over 2007. The increase in total revenue
was primarily attributable to an increase in non-hardware sales, an increase in the number of hardware DIGIPASS units sold and the impact of changes in currency rates as described previously, partially offset by a decline in the average price of
hardware DIGIPASS units sold.

We believe that the increase in our non-hardware revenue and hardware DIGIPASS units sold was
attributable to the strength and flexibility of our VACMAN Controller software platform, growth in our distribution channel, our increased investment in sales staff and marketing programs, the markets increased awareness of the need for strong
authentication to combat identity theft and our ability to deploy large volumes of high-quality products at an affordable price. The strategy introduced in the beginning of 2006 of being the full-option, all-terrain company allowed us to compete
effectively in both the Banking market and Enterprise and Application Security markets. With the introduction of our DIGIPASSPlus strategy in January 2006, we saw an increase in revenue for software-based DIGIPASSES.

##### Table of Contents

As noted in the table above, revenue from EMEA and Other Countries increased while revenue
from the U.S. and Asia Pacific declined. The growth in EMEA of $7,785, or 10%, over 2007, was attributable to increased sales of DIGIPASS products in both the Banking and Enterprise and Application Security markets and the impact of changes in
currency rates. The growth in Other Countries, $10,305, or 68%, over 2007, was primarily attributable to increased sales of DIGIPASS products in the Banking market. The growth in both of these geographic areas reflects our general strategy of
penetrating new markets by selling into banks first. Once established, as is the case in EMEA, we then leverage the awareness of our products created by the banks by investing in staff and programs targeted to sell into the Enterprise and
Application Security market.

Revenue decreased $1,481, or 16%, in the U.S. from 2007. The decline in the U.S. reflects lower
sales of DIGIPASS products in both the Banking and Enterprise and Application Security markets.

Revenue decreased $3,612, or
26%, in Asia Pacific compared to 2007. The decline in the Asia Pacific region reflected lower sales of DIGIPASS products in both the Banking and Enterprise and Application Security markets.

Revenue by Target Market:Revenue is generated currently from two primary markets, (1) Banking and (2) Enterprise
and Application Security, through the use of both direct and indirect sales channels. The Enterprise and Application Security market includes products used by employees of corporations to secure their internal networks (the enterprise security
market) and business-to-business, business-to-consumer, e-commerce, e-government, e-gaming and other vertical applications (the application security market) that are not related to banking or finance. Management currently views the Enterprise and
Application Security market as one market because the same products are sold, through the same channels to both customer groups. Sales to the Enterprise and Application Security market are generally for smaller quantities and higher prices than
sales made to the Banking market. The breakdown of revenue between the two primary markets is as follows:

2009 Compared to 2008

Revenue for the full year 2009 from the Banking market decreased $34,044 or 31% from 2008 and revenue from the Enterprise
and Application Security market increased $2,762 or 11% in the same period.

The decline in the Banking market reflects a
decline in products sold, both hardware and non-hardware, and the strengthening of the U.S. Dollar as compared to the Euro, as previously noted. We believe that banks in many, but not all, of our markets have been affected by the financial
crisis. As a result, during the first three quarters of 2009, we believe that bank management teams increased their focus on short-term objectives while their internal structures were being realigned based on new ownership or new government rules.
Also, given the worldwide recession, we believe that many banks were postponing marketing campaigns and related large-scale deployments of our products until a time when such marketing campaigns are expected to yield a higher return. For several
consecutive quarters the banks placed smaller orders, which we believe was done primarily to meet their short-term needs. In the fourth quarter of 2009, however, the banks began issuing requests for information and proposals for new projects and
placed larger orders for delivery in the quarter, in part we believe to spend

remaining budgets for 2009 and in part reflecting a return to a more normal level of business. For 2010, we expect the order volume from banks to exceed the order levels in 2009, reflecting
modest increases, but we do not anticipate that such orders will return to pre-economic/financial crisis levels.

The increase
in the Enterprise and Application Security market was primarily attributable to an increase in the number of products shipped partially offset by the strengthening of the U.S. Dollar as compared to the Euro. We believe that the growth in
products shipped reflects the benefits resulting from a number of investments that we have made over the last several years to improve our competitive position, including investments in new products, training for the channel and the addition of new
distributors to our channel. The increase in revenues from the Enterprise and Application Security market also reflects the penetration of new vertical markets, such as on-line gaming.

2008 Compared to 2007

Revenue from the Banking market increased $8,628 or 9% in 2008 over 2007 and revenue from the Enterprise and Application Security market increased $4,369 or 22% in the same period. Growth in revenue from
the Banking market reflected our continued expansion into new geographic markets and the strength of our installed base in EMEA. Growth in revenue from the Enterprise and Application Security market resulted from the continued investment in sales
staff and products dedicated to the Enterprise and Application Security market as well as the execution of our strategy to sell into applications in new vertical markets such as on-line gaming.

The increase in revenue in both markets was also attributable, in part, to the continued maturation of the indirect sales channel, which
includes distributors, resellers, and solution partners, partially offset by a reduction in the number of distributors. The number of distributors decreased to 70 at the end of 2008 from 77 at the end of 2007 and reflected actions taken to terminate
the relationship with distributors that were not meeting our expectations for performance. The indirect sales channel supplements the companys direct sales force in the Banking market and was the primary source of revenue in the Enterprise and
Application Security market.

Gross Profit

2009 Compared to 2008

Consolidated gross profit for 2009 was
$71,160, a decrease of $20,810, or 23%, from the $91,970 reported for 2008. Gross profit as a percentage of revenue (gross profit margin) was 70% in 2009, as compared to 69% in 2008. The increase in the gross profit margin primarily
reflects the benefit from:



| |  |  | An impairment charge in 2008 of $1,276 million related to development costs of a project that did not result in revenues as expected and a benefit of
$390 in 2009 from the release of warranty reserves that were determined to no longer be needed; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An increase in Enterprise and Application Security revenues as a percentage of total revenues;
| | - |  | ----------------------------------------------------------------------------------------------

partially offset by the:



| |  |  | Impact from the strengthening of the U.S. Dollar compared to the Euro and Australian Dollar;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Reduction in non-hardware sales as a percentage of revenue; and
| | - |  | ---------------------------------------------------------------



| |  |  | An increase in sales of card readers as a percentage of total revenue.
| | - |  | ----------------------------------------------------------------------

The impairment charge in 2008 reduced the gross profit margin by 1.0 percentage point.

Revenue from our Enterprise and Application Security markets was 26% of revenue of total full year 2009 compared to 18% of revenue for full
year 2008. The gross profit margin from our Enterprise and Application Security Business is approximately 20 to 25 percentage points higher than in the Banking market because sales in the Enterprise and Application Security market are generally for
lower quantities and higher prices than in the Banking market. We plan to continue to invest in both the Banking market and the Enterprise and Application Security market and the overall mix between the two markets will vary in the future based on
the growth rates in each of the markets.

The majority of our inventory purchases are denominated in U.S. Dollars. Also, as
previously noted, our sales are denominated in various currencies including the Euro and Australian Dollar. As the U.S. Dollar has strengthened, when compared to the Euro and Australian Dollar in the same periods in the prior year, revenue from
sales made in Euros and Australian Dollars decreased, as measured in U.S. Dollars, without a corresponding decrease in cost of goods sold. The impact from changes in currency rates as noted above is estimated to have decreased revenue by
approximately $2,513 for the full year 2009. Had the currency rates in 2009 been equal to the rates in 2008, the gross profit rate would have been approximately 0.7 percentage points higher for the year ended December 31, 2009.

Non-hardware revenue, which can have a gross profit margin that is approximately 20 to 30 percentage points higher than hardware-related
revenue, depending on the model and quantity of the hardware units sold, was 23% of revenue for full year 2009 compared to 25% of total revenue for full year 2008. We plan to continue to focus on sales of our non-hardware revenue items and expect
that they will increase as a percentage of our total revenue in future periods.

Card readers, which can have a gross profit
margin that is approximately 25 to 35 percentage points lower than other hardware-related margins, due to competitive pricing pressures, were 18% of our revenue for full year 2009, respectively, compared to 17% for full year 2008. We expect that
there will be continued pressure on the pricing of card readers as there are a number of competitors in the EMV market that produce products with fewer features than our products and at lower costs.

2008 Compared to 2007

Consolidated gross profit for 2008 was $91,970, an increase of $12,858, or 16%, from the $79,112 reported for 2007. Gross profit as a
percentage of revenue (gross profit margin) was 69% in 2008, as compared to 66% in 2007. The increase in the gross profit margin primarily reflects:



| |  |  | An increase in our non-hardware product revenue as a percentage of our total revenue;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | The strengthening of the Euro and Australian Dollar compared to the U.S. Dollar; and
| | - |  | ------------------------------------------------------------------------------------



| |  |  | A reduction in the cost of product manufactured;
| | - |  | ------------------------------------------------

partially offset by



| |  |  | A decline in the average sales price per hardware DIGIPASS unit; and
| | - |  | --------------------------------------------------------------------



| |  |  | An impairment charge related to the development cost of a project that did not result in revenues in 2008 as expected.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

Non-hardware product revenue includes revenue from VACMAN Controller, software versions of our DIGIPASSES, maintenance, support,
customization, and other non-manufactured products. Non-hardware product revenue increased to approximately 25% of revenue in 2008 from 14% in 2007. The gross profit on non-hardware products is substantially higher than on hardware products.

Our purchases of inventory are denominated in U.S. Dollars. Also, as previously noted, the company denominates a portion of
its sales in Euros in an effort to offset the effects of currency fluctuations on operating expenses. The increase in revenue and gross profit resulting from changes in currency rates in 2008 was estimated to be $4,188, as noted above. Had the
currency rates remained unchanged in 2008 compared to 2007, we estimate that our gross profit margin would have been approximately 1.0 percentage point lower.

The average cost per DIGIPASS unit manufactured was lower in 2008 than in 2007 due to our continued focus on the design of the product, including the cost of its components, and a favorable change in the
mix of product sold in 2008 compared to 2007. In 2008, the number of card readers sold, which are more expensive to produce than most of our other products, declined from 25% of revenue in 2007 to 14% of revenue in 2008.

The decline in the average sales price per hardware DIGIPASS unit sold reflects the impact of competitive pricing pressures, the mix of
product sold and our strategy of providing discounts for large volume purchases. The aforementioned reduction in card readers sold had a negative impact on the average sales price as the average selling price of a card reader is higher than the
average price for our consumer DIGIPASS units.

In 2008, we invested $1,276 in a project that was expected to result in
substantial incremental revenue in 2008. We did not realize any revenue from the project in 2008 and recorded an impairment charge for the full amount of the investment in the fourth quarter of the year.

Operating Expenses

Our operating expenses are generally based on anticipated revenue levels and the majority of such expenses are fixed over short periods of time. As a result, small variations in the amount of revenue recognized in any given quarter could
cause significant variations in the quarter-to-quarter comparisons of either the absolute amounts of operating income or operating income as a percentage of revenue.

The most significant factor driving our operating expenses is our headcount. Direct compensation and benefit plan expenses generally represent between 55% and 60% of our operating expenses. In addition, a
number of other expense categories are directly related to headcount. As mentioned earlier, we implemented a cost containment initiative in 2009 that included, but was not limited to, a hiring freeze in all areas with the exception of sales and
related support areas.

##### Table of Contents

In addition to headcount, the comparison of operating expenses in 2009 to 2008 was impacted
significantly by our non-cash compensation expenses. Non-cash compensation expenses generally relate to stock-based, long-term performance incentives. For the full year of 2009, operating expenses included a benefit of $309 related to stock-based
incentive plans. In 2009, we reversed $2,002 of accruals that had been established in prior years for long-term performance incentives where it is no longer likely that the performance targets will be met. Stock-based incentive plan expenses for
full year 2008 were $3,117.

With the expected growth of revenues in 2010, we have removed the hiring freeze and other cost
containment initiatives. In addition, to ensure that we are in the best competitive position possible, we have developed hiring and other investment plans for 2010 that are expected to help accelerate our revenue growth in years beyond 2010. As a
result of those hiring and other investment plans, and the fact that the benefit we received in 2009 from the reversal of long-term performance incentives is unlikely to recur in 2010, we expect that growth in operating expenses in 2010 will exceed
growth in our revenues in 2010.

Sales and Marketing Expenses

2009 Compared to 2008

Consolidated sales and marketing expenses for the year ended December 31, 2009 were $30,299, a decrease of $5,053, or 14%, from $35,352 reported for 2008. This decrease in sales and marketing
expenses is primarily related to:



| |  |  | the benefit of a stronger U.S. Dollar compared to the Euro;
| | - |  | -----------------------------------------------------------



| |  |  | lower compensation expenses;
| | - |  | ----------------------------



| |  |  | lower marketing expenses; and
| | - |  | -----------------------------



| |  |  | lower travel expenses.
| | - |  | ----------------------

We estimate that the strengthening of the U.S. dollar to other currencies, primarily the Euro and Australian dollar, reduced sales and marketing expenses by approximately $1,730 in 2009 compared to 2008.

While our average headcount increased, our compensation expenses declined as a result of the changes in currency rates and
the benefit from the reduction of the accruals for long-term incentive plans. The average full-time sales, marketing and operations employee headcount increased 5% to 161 in 2009 from 153 in 2008. At year-end 2009, the company employed 156 sales,
marketing and operations employees.

Given the difficult economic environment in 2009, we reduced our spending on marketing
activities and travel as part of our cost containment programs.

For 2010, we plan to increase our spending in each of the
core sales, marketing and operations functions. We plan to add sales staff to strengthen our position in key countries, to target new vertical applications and increase our focus on the indirect sales channel. We also plan to increase our marketing
expenses to target areas that we believe provide substantial further growth opportunities. With our plan to increase our headcount, we expect that our other marketing related expenses, such as recruiting and travel, will also increase in 2010.

2008 Compared to 2007

Consolidated sales and marketing expenses for the year ended December 31, 2008 were $35,352, an increase of $8,171, or 30%, from $27,181 reported for 2007.

The increase was primarily due to an increase in average headcount and related compensation expenses, costs related to opening sales offices
in new geographies, an increase in marketing programs and materials, and an increase in travel expenses.

##### Table of Contents

The average full-time sales, marketing and operations employee headcount increased 31% to
153 in 2008 from 117 in 2007. At year-end 2008, the company employed 176 full-time sales, marketing and operations employees.

Research and Development Expenses

2009 Compared to 2008

Consolidated research and development costs for the year ended December 31, 2009 were $11,582, a decrease of $36, or less than 1%, from
the $11,618 reported for 2008. The change in research and development was primarily attributable to increased compensation expenses related to increased headcount, offset by the benefit from the reduction of the accruals for long-term incentive
plans and the benefit from the changes in currency rates.

The average full-time sales, research and development headcount
increased 18% to 93 in 2009 from 79 in 2008. At year-end 2009, the company employed 92 full-time research and development employees.

We estimate that the strengthening of the U.S. dollar to other currencies, primarily the Euro and Australian dollar, reduced research and development expenses by approximately $838 in 2009 compared to 2008.

2008 Compared to 2007

Consolidated research and development costs for the year ended December 31, 2008 were $11,618, an increase of $2,178, or 23%, from the $9,440 reported for 2007. The increase in research and
development was primarily attributable to increased compensation expenses related to increased headcount.

The average
full-time sales, research and development headcount increased 16% to 79 in 2008 from 68 in 2007. At year-end 2008, the company employed 87 full-time research and development employees.

General and Administrative Expenses

2009 Compared to 2008

Consolidated general and administrative expenses for the year ended December 31, 2009 were $16,183, a decrease of $54 or
less than 1%, from the $16,237 reported for 2008. The decrease in general and administrative expenses was primarily attributable to the benefit from the reduction of the accruals for long-term incentive plans, the benefit from the changes in
currency rates, lower travel, recruiting and professional fees related to cost containment actions, partially offset by the increased compensation expenses related to increased headcount, increased depreciation related to prior year investments in
systems and increased software licensing costs, also related to prior year investments in systems.

We estimate that the
strengthening of the U.S. dollar to other currencies, primarily the Euro and Australian dollar, reduced general and administrative expenses by approximately $532 in 2009 compared to 2008.

The average full-time general and administrative employee headcount increased 21% to 47 in 2009 from 39 in 2008. At year-end 2009, the
company employed 46 general and administrative employees.

2008 Compared to 2007

Consolidated general and administrative expenses for the year ended December 31, 2008 were $16,237, an increase of $5,668 or 54%, from
the $10,569 reported for 2007.



39



---

##### Table of Contents

The increase in the general and administrative expense primarily reflected increased
compensation expenses related to increased headcount, increased recruiting fees related to our aggressive hiring plan, increased travel due to the increase in staff, and increased professional fees. The increase in professional fees primarily
reflected higher costs associated with implementation of our worldwide strategy for the ownership of our intellectual property and legal costs associated with the set up of our new subsidiaries.

The average full-time general and administrative employee headcount increased 50% to 39 in 2008 from 26 in 2007. At year-end 2008, the
company employed 48 general and administrative employees.

Amortization Expense

2009 Compared to 2008

Amortization expense for 2009 was $453, a decrease of $173 or 28% from $626 reported for 2008. The decrease reflected the fact that the amortizable assets related to the acquisition of our Australian
subsidiary, Identikey, in 2001 were fully amortized in 2008.

2008 Compared to 2007

Amortization expense for 2008 was $626, a decrease of $403 or 39% from $1,029 reported for 2007. The decrease reflected the fact that the
amortizable assets related to the acquisition of our Australian subsidiary, Identikey, in 2001 were fully amortized in 2008.

Interest
Income, Net

2009 Compared to 2008

Consolidated net interest income was $572 in 2009 compared to $990 in 2008. The decrease in net interest income primarily reflected a decrease in the rate of return on higher average net cash balances.
Average net cash balances were $64,292 in 2009, an increase of $17,324 or 37% from $46,968 in 2008. Our return on average net cash balances was 0.9% in 2009 compared to 2.11% in 2008. The reduction in the rate of return reflected the impact of
various stimulus packages offered by governments to banks in the regions in which we operate. The stimulus packages effectively reduced the cost of funds to each bank, thereby reducing the interest rate the banks were willing to pay on deposits. We
expect that the lower rates of return will continue in 2010.

2008 Compared to 2007

Consolidated net interest income was $990 in 2008 compared to $479 in 2007. The increase in income primarily reflected an increase in our
average net cash balances. Average net cash balances were $46,968 in 2008, an increase of $20,764 or 79% from $26,204 in 2007. Our return on average net cash balances was 2.11% in 2008 compared to 1.83% in 2007.

Other Income (Expense), net

2009 Compared to 2008

Other income (expense), net in 2009 primarily included exchange gains (losses) on
transactions that are denominated in currencies other than a subsidiarys functional currency and subsidies received from foreign governments related to increasing trade in other countries. Other income was $2,107 in 2009 compared to expense of
$209 in 2008 and reflects an increase in exchange gains of $1,415 and an increase in other income of $901. We realized exchange gains of $835 in 2009 compared to exchange losses of $580 in 2008. In 2010, we expect that our other income from
government subsidies will decline as government incentives put in place to stimulate the economies in some of the countries in which we operate lapse.

2008 Compared to 2007

Other income (expense), net in 2008 primarily included exchange gains (losses) on transactions that are denominated in currencies other than
a subsidiarys functional currency and subsidies received from foreign governments related to increasing trade in other countries. Other expense was $209 in 2008 compared to $384 in 2007 and reflects a decrease in exchange losses of $326 and a
decrease in other income of $151. We realized exchange losses of $580 in 2008 compared to exchange losses of $906 in 2007.

Income Taxes

2009 Compared to 2008

Income tax expense for 2009 was $3,460, compared to $4,627 in 2008. The effective tax rate in 2009 was 23%, an increase of 7 percentage points from 16% in 2008. The rate in 2009 reflected the lower level
of pretax profit earned in 2009 in tax jurisdictions that either have a lower statutory tax rate or have tax loss carry forwards that have been reserved. We expect that our effective tax rate may vary significantly in future years as actual earnings
or losses are realized in countries with lower tax rates or with loss carryforwards that have been reserved.

2008 Compared
to 2007

Income tax expense for 2008 was $4,627, compared to $10,025 in 2007. The effective tax rate in 2008 was 16.0%, a
decrease of 16.4 percentage points from 32.4% in 2007. The rate in 2008 reflected the full-year benefit realized from the new strategy related to the ownership of our intellectual property implemented in the second half of 2007, a benefit realized
from using net operating losses carryforwards (NOLs) that had been reserved fully in prior years and the reversal of the reserve of an NOL for one of our foreign subsidiaries that we are more likely than not to use based on our current
tax strategy.

Loss Carryforwards Available

At December 31, 2009, we had deferred tax assets of $9,496 including deferred tax assets related to significant tax loss carryforwards
in the U.S. and in our foreign operations. We also had a valuation allowance of $8,263 against those deferred tax assets. The tax loss carryforwards expire in varying amounts beginning in 2018 and continuing through 2029. Such tax loss carryforwards
may provide an offset to future tax liabilities. In addition to the reduction in tax liabilities, a reduction in the valuation reserve may be possible if it is more likely than not that we will realize the benefit of the deferred tax asset. The
reduction in the reserve would reduce income tax expense in the period it is reduced. See Note 5 to the consolidated financial statements for more information on tax loss carryforwards.

Liquidity and Capital Resources

At December 31, 2009, we had net cash
balances (total cash, cash equivalents and restricted cash less bank borrowings), totaling $67,601. We had no outstanding term debt or restricted cash at December 31, 2009.

Cash generated from operating activities was $12,828 during the year ended December 31, 2009. During 2009, we used $2,728 for investing
activities, primarily for additions to property and equipment, and provided $119 from financing activities, primarily consisting of proceeds from the exercise of stock options. Capital expenditures were $2,169 for the year ended December 31,
2009.

Cash generated from operating activities was $23,506 during the year ended December 31, 2008. During 2008, we used
$3,068 for investing activities, primarily for additions to property and equipment, and provided $354 in financing activities from the exercise of stock options. Capital expenditures were $2,812 for the year ended December 31, 2008.

We maintain a line of credit with Fortis Bank, SA/NV, Brussels, Zurich Branch. Under terms of the agreement, we can borrow an amount
equal to 80% of our Belgium subsidiarys defined accounts receivable up

to a maximum of 5,000 Euros. Borrowing under the line of credit may be denominated in Euros, U.S. Dollars or Swiss Francs. If the borrowings are denominated in Euros, we are obligated to pay
interest at the monthly average of the EONIA (Euro Over Night Index Average) plus 2.5% per year. If the borrowings are denominated in U.S. Dollars, we are obligated to pay interest at the U.S. Dollar Fed Fund Rate plus 2.5% per year.
If the borrowings are denominated in Swiss Francs, we are obligated to pay interest at the Swiss National Bank Repo rate plus 2.5% per year. Either party can terminate the credit line with 14 days notice without penalty. If terminated, all
borrowings under the line then outstanding would be due and payable. The bank can also terminate the credit line immediately if VASCO fails to observe the specific terms of the credit line, becomes insolvent, ceases operation or experiences a change
in control. We had no borrowings under the credit line at December 31, 2009.

The net effect of 2009 activity resulted in
an increase in net cash of $9,887 and a net cash balance of $67,601 at December 31, 2009, compared to $57,714 at the end of 2008. Our working capital at December 31, 2009 was $87,632, an increase of $11,702 or 15% from $75,930 at
December 31, 2008. The change is primarily attributable to the generation of positive cash flow from operations in 2009. Our current ratio was 4.8 to 1.0 at December 31, 2009. We believe that our current cash balances, credit available
under our existing overdraft agreement and the anticipated cash generated from operations, including deposits received on orders of DIGIPASS to be delivered in 2010, will be sufficient to meet our anticipated cash needs for the next 12 months.

The net effect of 2008 activity resulted in an increase in net cash of $18,881 and a net cash balance of $57,714 at
December 31, 2008, compared to $38,833 at the end of 2007. Our working capital at December 31, 2008 was $75,930, an increase of $23,492 or 45% from $52,438 at December 31, 2007. The change was primarily attributable to the generation
of positive cash flow from operations in 2008. Our current ratio was 3.5 to 1.0 at December 31, 2008.

While we believe
that our financial resources and current borrowing arrangements are adequate to meet our operating needs over the next twelve months, we anticipate that the difficult current economic conditions that exist on a worldwide basis today may require us
to modify our business plans. In the current economic environment there is an increased risk that customers may delay their orders until the economic conditions stabilize or improve. If a significant number of orders are delayed for an indefinite
period of time, our revenue and cash receipts may not be sufficient to meet the operating needs of the business. If this is the case, we may need to borrow against our credit line, significantly reduce our workforce, sell certain of our assets,
enter into strategic relationships or business combinations, discontinue some or all of our operations, or take other similar restructuring actions. While we expect that these actions would result in a reduction of recurring costs, they also may
result in a reduction of recurring revenue and cash receipts. It is also likely that we would incur substantial non-recurring costs to implement one or more of these restructuring actions. See our Risks Related to Our Business in
Item 1A, Risk Factors.

##### Table of Contents

The company had $470 and $475 of unrecognized tax benefits as of December 31, 2009 and
2008, respectively, which have been set aside in a reserve in accordance with ASC 740-10. These amounts are not included in the above table as the timing of payment of such obligations, if any, is not determinable.

Critical Accounting Policies and Estimates

Managements Discussion and Analysis of Financial Condition and Results of Operations discusses our consolidated financial statements, which have been prepared in accordance with accounting
principles generally accepted in the U.S. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and
liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period.

On an on-going basis, management evaluates its estimates and judgments, including those related to bad debts, net realizable value of inventory and intangible assets. Management bases its estimates and
judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Management believes the following critical accounting policies, among others, affect its more significant judgments and
estimates used in the preparation of its consolidated financial statements.

Revenue Recognition

We recognize revenue in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Subtopic 985-605
that addresses the accounting for revenue transactions involving software, as well as Staff Accounting Bulletin 104. Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has occurred, the fee is fixed or
determinable and collection of the revenue is probable.

Hardware Revenue and License Fees: Revenue from the sale of computer
security hardware or the license of software is recorded upon shipment or, if an acceptance period is allowed, at the later of shipment or customer acceptance. No significant obligations or contingencies exist with regard to delivery, customer
acceptance or rights of return at the time revenue is recognized.

Maintenance and Support Agreements: Maintenance and support
agreements generally call for us to provide software updates and technical support, respectively, to customers. Revenue on maintenance and technical support is deferred and recognized ratably over the term of the maintenance and support agreements.

Consulting and Education Services: We provide consulting and education services to our customers. Revenue from such services
is recognized during the period in which the services are performed.

Multiple-Element Arrangements: We allocate revenue to
the various elements of the arrangements based on the estimated fair value of each deliverable, as required by ASC 605-25. The fair value for each element is based on the price charged when that element is sold separately, renewal rates and other
methods, such as prices established by management. The estimated fair value of undelivered elements is deferred and recorded as revenue when services are performed or products are delivered.

When tokens and software licenses are included in multiple element arrangements, they are generally delivered elements in such arrangements.
When tokens and software are delivered elements, we use the residual method for determining the amount of revenue to recognize for token and software licenses if we have vendor specific objective evidence (VSOE) for all of the undelivered elements.
Any discount provided to the customer is applied fully to the delivered elements in such an arrangement. We defer the revenue for tokens and software in any multiple element arrangement where we do not have VSOE for any undelivered element. VSOE of
fair value



43



---

##### Table of Contents

of PCS agreements is based on separate sales transactions on a worldwide basis. In sales arrangements where VSOE of fair value has not been established, revenue for all elements is deferred and
amortized over the life of the arrangement.

We recognize revenue from sales to distributors and resellers on the same basis
as sales made directly to customers. We recognize revenue when there is persuasive evidence that an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection of the revenue is probable.

For large-volume transactions, we may negotiate a specific price that is based on the number of users of the software license or quantities
of hardware supplied. The per unit prices for large-volume transactions are generally lower than transactions for smaller quantities and the price differences are commonly referred to as volume-purchase discounts.

Allowance for Doubtful Accounts

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make payments for goods and services. We analyze accounts receivable, customer credit-worthiness, current economic trends and
changes in our customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. The allowance is based on a specific review of all significant past-due accounts. If the financial condition of our customers deteriorates,
resulting in an impairment of their ability to make payments, additional allowances may be required.

Net Realizable Value of Inventory

We write down inventory where it appears that the carrying cost of the inventory may not be recovered through subsequent
sale of the inventory. We analyze the quantity of inventory on hand, the quantity sold in the past year, the anticipated sales volume in the form of sales to new customers as well as sales to previous customers, the expected sales price and the cost
of making the sale when evaluating the valuation of our inventory. If the sales volume or sales price of a specific model declines significantly, additional write-downs may be required.

Valuation of Goodwill and Other Intangible Assets and Software Development Costs

Impairment of Long-Lived and Intangible Assets: Definite-lived intangible assets include proprietary technology and other intangible assets. Intangible assets other than patents with definite lives are amortized over the useful life,
generally three to seven years for proprietary technology. Patents are amortized over the life of the patent, generally 20 years in the U.S.

Long-lived assets, including property, plant and equipment, definite-lived intangible assets being amortized and capitalized software costs, are reviewed for impairment in accordance with ACS 360-10-25
through 35, Property, Plant and Equipment, whenever events or changes in circumstances indicate that the carrying amount of the long-lived asset may not be recoverable. An impairment loss shall be recognized if the carrying amount of a long-lived
asset exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If it is determined that an impairment loss has occurred, the loss is measured as the amount by which the carrying amount of
the long-lived asset exceeds its fair value. Long-lived assets held for sale are reported at the lower of carrying value or fair value less cost to sell.

Goodwill and other Intangible Assets: We account for goodwill and indefinite-lived intangible assets in accordance with ASC 350-20-25 through 35, Intangibles-Goodwill and Other. We assess the
impairment of goodwill and intangible assets with indefinite lives each year-end or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors considered important which could trigger an impairment
review include significant underperformance relative to expected historical or projected future operating results, significant changes in the manner of our use of the acquired assets or the strategy for our



44

##### Table of Contents

overall business, and significant negative industry or economic trends. Once identified, the amount of the impairment is computed by comparing the carrying value of the assets to the fair value.
Fair value for goodwill is determined using our stock price which is a level 1 valuation, as defined in ASC 820-10. Fair value for trademarks is based on discounted estimated future cash flows, which is a level 3 valuation. We have not recognized
any impairment for the years ended December 31, 2009, 2008 or 2007 as the fair value of our reporting unit substantially exceeds our carrying amount.

Income Taxes:

At December 31, 2009, we had U.S. net operating loss
(NOL) carryforwards of $23,204 and foreign NOL carryforwards of $5,391. A portion of such losses are available to offset future taxable income in the respective jurisdictions. ASC 740-10, requires that valuation allowances be established for
deferred tax assets if it is more likely than not that the assets will not be realized. We have provided valuation allowances against the entire U.S. NOL and a substantial portion of the foreign NOLs. (See Note 5 to the consolidated financial
statements for more information regarding the NOL and valuation allowance.)

Also in accordance with ASC 740-10, we have
established a reserve related to tax benefits of uncertain tax positions. We have identified one exposure concerning cost allocations used in the implementation of our worldwide strategy related to the ownership of our intellectual property for
which we had a reserve of $470 and $475 at December 31, 2009 and 2008, respectively, each of which is an offset to our U.S. deferred tax asset at the end of each respective period.

Recently Issued Accounting Pronouncements

Accounting for Business Combinations

Effective January 1, 2009, we adopted the provisions of ASC 805-10, Business Combinations. ASC 805-10
establishes principles and requirements for how an acquirer in a business combination recognizes and measures the assets acquired, liabilities assumed, and any non-controlling interest in the acquiree. The adoption of ASC 805-10 did not have a
material impact on our consolidated financial position or results of operations but will impact the accounting for future business combinations.

Fair Value Measurements

Effective January 1, 2009, we adopted the provisions of ASC 820, Fair Value
Measurements, for certain nonfinancial assets and liabilities. ASC 820 establishes a framework for measuring fair value under other accounting pronouncements that require fair value measurements and expands disclosures about such measurements.
ASC 820 does not require any new fair value measurements, but rather it creates a consistent method for calculating fair value where the use of fair value is required for financial reporting. A portion of ASC 820 was effective for financial
statements issued for fiscal years beginning after November 15, 2007. On November 14, 2007, the FASB deferred the effective date for certain nonfinancial assets and liabilities, except those that are recognized or disclosed at fair value
in the financial statements on a recurring basis. Neither the adoption of a portion of ASC 820 in 2008 nor the adoption of the final provisions in 2009 had a significant impact on our consolidated financial position, results of operations or cash
flows in either year.

Software

In October 2009, the FASB issued ASU 2009-14, Software, Certain Revenue Arrangements that Include Software Elements. ASU 2009-14 provides guidance to enable companies to determine if the products
they sell should be accounted for as software under ASC 985-605. Arrangements that are no longer defined as software will be accounted for under ASC 605-25, for separating consideration in multiple-deliverable arrangements. Under ASU 2009-14,
tangible products containing software components and non-software components that function together to deliver the tangible products essential functionality will no longer fall



45

##### Table of Contents

within the scope of ASC 985-605. ASU 2009-14, however, also indicates that the non-software elements of the tangible product must substantively contribute to the tangible products essential
functionality and should not simply provide a mechanism to deliver the software to the customer. Companies that are affected by ASU 2009-14 are required to provide disclosures that are included within the amendments in ASU 2009-13, a discussion of
which follows in this Form 10-K.

Revenue Recognition

In October 2009, the FASB issued ASU 2009-13, Revenue Recognition, Multiple-Deliverable Revenue Arrangements. ASU 2009-13 amends the criteria in ASC 605-25 for separating consideration in multiple-
deliverable arrangements and is expected to provide companies with the ability to separate deliverables in more circumstances than is allowed under current U.S. GAAP. In addition, the amendments in ASU 2009-13 establish a selling price hierarchy for
determining the selling price of a deliverable. The selling price used for each deliverable will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated
selling price if neither vendor-specific objective evidence or third-party evidence is available. Under this update, the term fair valuewill be replaced with selling price to clarify that the allocation of revenue is based on
entity-specific assumptions rather than assumptions of a marketplace participant.

ASU 2009-13 also eliminates the residual
method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. The relative selling price method allocates any discount in the
arrangement proportionally to each deliverable on the basis of each deliverables selling price.

Both ASU 2009-13 and
ASU 2009-14 will be effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted and VASCO intends to adopt both Updates effective
January 1, 2011. As a result of adoption of the Updates, we expect that:



| | 1. | The sales of some of our products will be defined as software sales and we will continue account for those transactions using ASC 985-605. Sales of some of our other
products, however, will no longer qualify as sales of software and will be accounted for under ASC 605-25.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | For items continuing to be classified as software, we do not expect that the allocation of consideration will be significantly different than is currently the case as
we have vendor-specific objective evidence for the most common type of undelivered items, such as maintenance and support. Further, we will continue to use the Residual Method to determine the value of delivered items with any discounts provided
under these arrangements being fully allocated to the delivered items.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | For sales of product that no longer qualify as software sales, we will allocate the arrangement consideration among each of the accounting units based on relative
selling price of each of the units with any discount on the transaction being split proportionately between delivered and undelivered accounting units. We do not expect that the allocation of purchase price among delivered and undelivered elements
to be significantly different than under our current accounting practices because, as noted above, we have vendor-specific objective evidence for the most common type of undelivered items and generally do not provide discounts that will
significantly impact the value determined using VSOE.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. | As a result, we do not expect that the impact of adopting ASU 2009-13 and ASU 2009-14 will have a material impact on the amount, pattern or timing of revenue
recognized.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------

From time to time, new accounting pronouncements are issued by the FASB or other standards setting
bodies that are adopted by us as of the specified effective date. Unless otherwise discussed, our management believes that the impact of recently issued standards that are not yet effective will not have a material impact on our consolidated
financial statements upon adoption.

Item 7A -Quantitative and Qualitative Disclosures about Market
Risk (In thousands)

Foreign Currency Exchange Risk  In 2009, approximately 93% of our business
was conducted outside the United States, primarily in Europe, Latin America and Asia/Pacific. A significant portion of our business operations is 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 one of our companies
transacts business in a currency that differs from its local currency. These adjustments are recorded as gains or losses in our statements of operations. Our business transactions are spread across numerous countries and currencies. This geographic
diversity reduces the risk to our operating results. As noted in Managements Discussion and Analysis above, we attempt to minimize the net impact of currency on operating earnings by denominating an amount of billings in a currency such that
it would provide a hedge against the operating expenses being incurred in that currency.

Interest Rate Risk We
have minimal interest rate risk. We had no debt outstanding at December 31, 2009. Our cash is invested in short-term instruments at current market rates. If rates were to increase or decrease by one percentage point, the companys interest
income would increase or decrease approximately $676 annually.

Impairment Risk At December 31, 2009, we
had goodwill of $13,813 and other intangible assets of $1,797, primarily related to the acquisition of Logico and Able in 2006. We will assess the net realizable value of goodwill at least annually, and we will also assess the net realizable value
of other intangible assets whenever events or circumstances change indicating that the carrying value may not be recoverable. While we did not experience impairment during the year ended December 31, 2009, we may incur impairment charges in
future periods.

Item 8 -Financial Statements and Supplementary Data

The information in response to this item is included in our consolidated financial statements, together with the report thereon of KPMG
LLP, appearing on pages F-1 through F-23 of this Form 10-K, and in Item 7 under the heading Managements Discussion and Analysis of Financial Condition and Results of Operations.

Item 9- Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A -Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, who, respectively, are our principal
executive officer and principal financial officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the
Exchange Act)) as of the end of the fiscal quarter ended December 31, 2009. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of the end of the end of the fiscal quarter ended
December 31, 2009, our disclosure controls and procedures were effective to provide assurance that (i) the information required to be disclosed by us in our reports that we file or submit under the Exchange Act is recorded, processed,
summarized and reported within the time periods specified in the SECs rules and forms, and (ii) information required to be disclosed by us in our reports that we file or submit under the Exchange Act is accumulated and communicated to our
management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Controls

There were no changes in the companys internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the
Exchange Act) during the fiscal quarter ended December 31, 2009, that have materially affected, or are reasonably likely to materially affect, the companys internal control over financial reporting.

Managements Annual Report on Internal Control over Financial Reporting

The management of VASCO Data Security International, Inc. is responsible for establishing and maintaining adequate internal control over
financial reporting. Our internal control system was designed to provide reasonable assurance to the companys management and board of directors regarding the preparation and fair presentation of published financial statements. Internal control
over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the companys principal executive and principal financial officers and effected by the
companys board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles and includes those policies and procedures that:



| |  |  | Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the
company;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the companys assets that
could have a material effect on the financial statements.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our management, including our Chief Executive
Officer and Chief Financial Officer, do not expect that our disclosure controls and procedures or internal control over financial reporting will prevent all error and all fraud. While our disclosure controls and procedures and internal control over
financial reporting are designed to provide reasonable assurance that their objectives are met, they can not provide absolute assurance. The design of a control system must reflect the fact that there are resource constraints, and the benefits of
controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues within a company are detected. The inherent limitations
include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people
or by management override of the controls. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.

Notwithstanding the limitations noted above, our principal executive officer and principal financial officer have both concluded that our
disclosure controls and procedures and internal control over financial reporting were effective at a reasonable level of assurance as of December 31, 2009.

Our management assessed the effectiveness of its internal control over financial reporting as of December 31, 2009. In making this assessment, it used the criteria based on the framework set forth by
the Committee of Sponsoring Organizations of the Treadway Commission in Internal Controls  Integrated Framework (COSO). Based on our assessments we believe that, as of December 31, 2009, our internal control over financial reporting is
effective based on those criteria.

Our independent registered public accounting firm, KPMG LLP, has issued an audit report on
the effectiveness of our internal control over financial reporting. This report appears below.

The Board of Directors and Stockholders

VASCO
Data Security International, Inc.:

We have audited VASCO Data Security International, Inc.s internal control over financial reporting as
of December 31, 2009, based on criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). VASCO Data Security International, Inc.s
management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Annual Report
on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed
to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over
financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could
have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not
prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies
or procedures may deteriorate.

In our opinion, VASCO Data Security International, Inc. maintained, in all material respects, effective
internal control over financial reporting as of December 31, 2009, based on criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of
VASCO Data Security International, Inc. and subsidiaries as of December 31, 2009 and 2008, and the related consolidated statements of operations, comprehensive income, stockholders equity, and cash flows for each of the years in the
three-year period ended December 31, 2009, and our report dated March 16, 2010 expressed an unqualified opinion on those consolidated financial statements.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

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, 2009 and 2008, and the related consolidated statements of operations, comprehensive income, stockholders equity, and cash flows for
each of the years in the three-year period ended December 31, 2009. In connection with our audits of the consolidated financial statements, we also have 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 the standards of
the Public Company Accounting Oversight Board (United States). 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 the Company as of December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 2009, in conformity with U.S. 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.

We also have audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), the Companys internal control over financial reporting as of December 31, 2009, based on criteria established in Internal
ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 16, 2010 expressed an unqualified opinion on the effectiveness of the Companys
internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(amounts in thousands, except per share data)

Unless otherwise noted, references in this Annual Report on Form 10-K to VASCO, company, we, our and us refer to VASCO Data Security
International, Inc. and its subsidiaries.

Note 1  Summary of Significant Accounting Policies

Nature of Operations

VASCO
Data Security International, Inc. and its wholly owned subsidiaries design, develop, market and support security products and services which manage and protect against unauthorized access to computer systems of corporate and government customers.
VASCO has operations in Austria, Australia, Bahrain, Belgium, Brazil, China, France, India, Japan, the Netherlands, Singapore, the U.K., the United States (U.S.) and Switzerland.

Principles of Consolidation

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

Estimates and Assumptions

The preparation of financial statements in
conformity with accounting principles generally accepted in the U.S. 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 revenue and expenses during the reporting period. Actual results could differ from those estimates.

Foreign Currency Translation and Transactions

The financial position and
results of the operations of the majority 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 charged or credited to other comprehensive income. Gains
and (losses) resulting from foreign currency transactions were $835, $(580) and $(906) in 2009, 2008 and 2007, respectively, and are included in other income in the consolidated statements of operations.

The financial position and results of our operations in Singapore and Switzerland are measured in U.S. Dollars. For these subsidiaries,
gains and losses that result from foreign currency transactions are included in the consolidated statements of operations.

Revenue
Recognition

We recognize revenue in accordance with Financial Accounting Standards Board (FASB) Accounting Standards
Codification (ASC) 985-605 that addresses the accounting for revenue transactions involving software, as well as Staff Accounting Bulletin 104. Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has
occurred, the fee is fixed or determinable and collection of the revenue is probable.

Hardware Revenue and License
Fees: Revenue from the sale of computer security hardware or the license of software is recorded upon shipment or, if an acceptance period is allowed, at the latter of shipment or customer acceptance. No significant obligations or contingencies
exist with regard to delivery, customer acceptance or rights of return at the time revenue is recognized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(amounts in thousands, except per share data)



Maintenance and Support Agreements:Maintenance and support agreements generally
call for us to provide software updates and technical support, respectively, to customers. Revenue on maintenance and technical support is deferred and recognized ratably over the term of the maintenance and support agreement.

Consulting and Education Services: We provide consulting and education services to our customers. Revenue from such services is
recognized during the period in which the services are performed.

Multiple-Element Arrangements: We allocate revenue
to the various elements of the arrangements based on the estimated fair value of each deliverable as required by ASC 605-25. The fair value for each element is based on the price charged when that element is sold separately, renewal rates and other
methods, such as prices established by management. The estimated fair value of undelivered elements is deferred and recorded as revenue when services are performed or products are delivered.

When tokens and software licenses are included in multiple element arrangements, they are generally delivered elements in such arrangements.
When tokens and software are delivered elements, we use the Residual Method (ASC 605-25) for determining the amount of revenue to recognize for token and software licenses if we have vendor specific objective evidence (VSOE) for all of the
undelivered elements. Any discount provided to the customer is applied fully to the delivered elements in such an arrangement. We defer the revenue for tokens and software in any multiple element arrangement where we do not have VSOE for any
undelivered element. VSOE of fair value of PCS agreements is based on separate sales transactions on a worldwide basis. In sales arrangements where VSOE of fair value has not been established, revenue for all elements is deferred and amortized over
the life of the arrangement. We recognize revenue from sales to distributors and resellers on the same basis as sales made directly to customers. We recognize revenue when there is persuasive evidence that an arrangement exists, delivery has
occurred, the fee is fixed or determinable and collection of the revenue is probable.

For large-volume transactions, we may
negotiate a specific price that is based on the number of users of the software license or quantities of hardware supplied. The per unit prices for large-volume transactions are generally lower than transactions for smaller quantities and the price
differences are commonly referred to as volume-purchase discounts.

All revenue is reported on a net basis, excluding any
sales or value added taxes.

Cash and Equivalents

Cash and equivalents are stated at cost plus accrued interest, which approximates fair value. Cash equivalents are high-quality short term money market instruments with original maturities of three
months or less. Cash and equivalents are held by a number of U.S. and non-U.S. commercial banks and money market investment funds with next day availability. Cash and equivalents at December 31, 2009 include $62,298 in money market investment
funds or demand bank deposits for which fair value is equal to cost. These investments are valued using level one inputs, as defined in ASC 820, Fair Value Measurements and Disclosures. Cash and equivalents also include $5,303
in bank certificates of deposit for which fair value was $5,322 at December 31, 2009. Bank certificates of deposit are valued using level two inputs, as defined by ASC 820.

Accounts Receivable and Allowance for Doubtful Accounts

The credit
worthiness of customers is reviewed prior to shipment. A reasonable expectation of collection is a requirement for revenue recognition. Verification of credit and/or the establishment of credit limits are part of

(amounts in thousands, except per share data)



the customer contract administration process. Credit limit adjustments for existing customers may result from the monthly review of outstanding accounts receivable. The company records trade
accounts receivable at invoice values, which are generally equal to fair value.

We maintain allowances for doubtful accounts
for estimated losses resulting from the inability of our customers to make payments for goods and services. We analyze accounts receivable balances, customer credit-worthiness, current economic trends and changes in our customer payment timing when
evaluating the adequacy of the allowance for doubtful accounts. The allowance is based on a specific review of all significant past-due accounts. If the financial condition of our customers deteriorates, resulting in an impairment of their ability
to make payments, additional allowances may be required.

Inventories

Inventories, consisting principally of hardware and component parts, are stated at the lower of cost or market. Cost is determined using the
first-in-first-out (FIFO) method. We write down inventory where it appears that the carrying cost of the inventory may not be recovered through subsequent sale of the inventory. We analyze the quantity of inventory on hand, the quantity sold in the
past year, the anticipated sales volume in the form of sales to new customers as well as sales to previous customers, the expected sales price and the cost of making the sale when evaluating the valuation of our inventory. If the sales volume or
sales price of a specific model declines significantly, additional write downs may be required.

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.

Research and Development Costs

Costs for research and development, principally the design and development of hardware, and the design and development of
software prior to the determination of technological feasibility, are expensed as incurred on a project-by-project basis.

Software
Development Costs

We capitalize software development costs in accordance with ASC 985-20. Research costs and software
development costs, prior to the establishment of technological feasibility, determined based upon the creation of a working model, are expensed as incurred. 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. Our policy is to amortize capitalized costs by the greater of (a) the ratio that current gross revenue for a product bear to the total of current and anticipated future gross revenue 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

We account for income taxes 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



F-10

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(amounts in thousands, except per share data)



amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. We measure deferred tax assets and liabilities 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. We recognize the effect of a change in tax rates on deferred tax assets and liabilities and in income in the period that
includes the enactment date.

We monitor our potential income tax exposures as required by ASC 740-10.

We have significant net operating loss carryforwards in the U.S. and other countries which are available to reduce the liability on future
taxable income. A valuation reserve has been provided to offset most of these future benefits because we have not determined that their realization is more likely than not.

Fair Value of Financial Instruments

At December 31, 2009 and 2008,
our financial instruments were cash equivalents, accounts receivable, notes receivable, accounts payable and accrued liabilities. The estimated fair value of our financial instruments has been determined by using available market information and
appropriate valuation methodologies, as described in Cash and Equivalents above. The fair values of the financial instruments were not materially different from their carrying amounts at December 31, 2009 and 2008.

Accounting for Leases

All
of our leases are operating leases. Rent expense on facility leases is charged evenly over the life of the lease, regardless of the timing of actual payments.

Goodwill and Other Intangibles

We account for goodwill and
indefinite-lived intangible assets in accordance with ASC 350-20. Indefinite-lived intangible assets include customer lists, proprietary technology and other intangible assets. Intangible assets other than patents with definite lives are amortized
over the useful life, generally three to seven years for proprietary technology. Patents are amortized over the life of the patent, generally 20 years in the U.S.

We assess the impairment of goodwill and intangible assets with indefinite lives each year-end or whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
Factors considered important which could trigger an impairment review include significant underperformance relative to expected historical or projected future operating results, significant changes in the manner of our use of the acquired assets or
the strategy for our overall business, and significant negative industry or economic trends. Once identified, the amount of the impairment is computed by comparing the carrying value of the assets to the fair value. Fair value for goodwill is
determined using our stock price which is a level 1 valuation, as defined in ASC 820-10. Fair value for trademarks is based on discounted estimated future cash flows, which a level 3 valuation. We have not recognized any impairment for the years
ended December 31, 2009, 2008 or 2007 as the fair value of our reporting unit substantially exceeds our carrying amount.

Stock-Based
Compensation

We have stock-based employee compensation plans, which are described more fully in Note 9. ASC 718-10
requires us to estimate the fair value of stock options granted to employees, directors and others and to record compensation expense equal to the estimated fair value. The fair value of stock options at the date of grant is



F-11

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

(amounts in thousands, except per share data)



estimated using the Black-Scholes option pricing model, with the expected life adjusted to reflect the effect of post-vesting restrictions. The assumptions used for the Black-Scholes model are
listed in Note 9. This compensation expense is recorded on a straight-line basis over the vesting period of the options.

Warranty

Warranties are provided on the sale of certain of our products and an accrual for estimated future claims is recorded at the
time revenue is recognized. Warranty reserves are based on past claims experience, sales history and other considerations. Our standard practice is to provide a warranty on our hardware products for either a one or two year period after the date of
purchase. Customers may purchase extended warranties covering periods from one to four years after the standard warranty period. We defer the revenue associated with the extended warranty and recognize it into income on a straight-line basis over
the extended warranty period. We have historically experienced minimal actual claims over the warranty period.

Reclassifications

Certain prior year amounts in the Consolidated Statement of Cash Flows have been reclassified to conform to the 2009
presentation, to present the details of the changes in assets and liabilities on a consistent basis.

Note 2  Inventories

Inventory is comprised of the following:



|                                   |  |              |       |      |   |

|Work-in-process and finished goods |  |              | 3,205 |      |   | 3,451 
|                                   |  |              |       |      |   |       
|Total                              |  | $            | 9,015 |      | $ | 13,376
|                                   |  |              |       |      |   |       

The decrease in component parts in 2009 compared to
2008 reflects a return to historical levels. Component parts inventory at December 31, 2008 was higher than normal due to purchases of processors that our supplier indicated were being discontinued and an increase resulting from lower than
expected demand in the fourth quarter of 2008.

Note 3  Goodwill and Other Intangibles

Intangible asset activity for the three years ended December 31, 2009 and the composition of the December 31, 2009 balance is as
follows. The majority of our goodwill and intangibles are denominated in local currencies and are subject to currency fluctuations. With the 2006 acquisition of VDS Austria (formerly Logico), we obtained net operating loss (NOL) carryforwards in
Austria. We provided a valuation reserve for the portion of the NOL which was not expected to be utilized. As subsequent earnings have exceeded our original expectations, a portion ($129 in 2008 and $85 in 2007) of the valuation reserve has been
applied as a reduction of goodwill. With the adoption of ASC 805-740 in 2009, additional valuation reserve adjustments will affect income tax expense rather than goodwill. In 2007, the $85 reduction in VDS Austria goodwill was offset by $200
increase resulting from a contingency payment made under the terms of the acquisition. In 2009 and 2008 we invested $241 and $386, respectively, in trademark protection and patent applications.

Note 4  Other Long-Term Assets

In 2006, the company contracted with a film producer to develop instructional video software to be used internally as a staff development
tool and to be marketed to potential customers and other parties. The cost of this software, $2,448, was capitalized in accordance with ASC 985-20 and was amortized on a straight line basis over a three year life.

A portion of the 2006 Able acquisition price is contingent upon the sellers continued employment with the company over a four year
period. Deemed compensation in the amount of 1,250 (equivalent to $1,570 at the historical exchange rate) has been recorded as an other asset and is being amortized over the required four year employment period. The amount to be amortized in
the next year has been classified as a prepaid expense.

The instructional video software and the deemed compensation are
denominated in local currencies and are subject to currency fluctuations.

At December 31, 2009, we had U.S. net operating loss (NOL) carryforwards of $23,204. Of this amount,
$16,643 is available to offset future taxable income. The remainder represents tax deductions for employee stock option gains which would be credited to paid-in capital. The U.S. loss carryforwards expire in varying amounts beginning in 2018 and
continuing through 2029. In addition, if certain substantial changes in the companys ownership were deemed to have occurred, there would be an annual limitation on the amount of the U.S. carryforwards that could be utilized. In 2009, 2008 and
2007, net utilization (creation) of deferred tax assets for U.S. net operating loss carryforwards were $(354), $1,471 and $(749), respectively.

At December 31, 2009, we also had foreign NOL carryforwards of $5,391. The foreign
NOL carryforwards have no expiration dates. Included in the foreign NOL carryforwards amount is $2,316 of tax losses obtained in the acquisition of VDS Austria (formerly Logico). Goodwill for the VDS Austria acquisition was reduced by $129 in 2008
and $85 in 2007, as the NOL utilized was greater than expected and our original forecasts were revised. With the adoption of ASC 805-740-30-3 in 2009, any future adjustments to the NOL carryforward valuation allowance for the VDS Austria acquisition
would affect income tax expense, rather than goodwill. In 2009, we recognized a $167 tax benefit for adjustment of this NOL valuation allowance. In 2009, 2008 and 2007, net utilization (creation) of deferred tax assets for foreign net operating loss
carryforwards, excluding goodwill adjustments related to VDS Austria, were $238, $224 and $65, respectively.

The company has
provided a valuation allowance at December 31, 2009 for all of its U.S. deferred tax assets and certain foreign deferred tax assets. 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.

The net change in the valuation allowance for the years ended December 31, 2009, 2008 and 2007 was a (decrease) increase of $(151),
$(2,977) and $445, respectively. This valuation allowance will be reviewed on a regular basis and adjustments made as appropriate. In addition to the utilization of NOLs in the U.S. and in foreign countries as noted above, the change in the
valuation allowance also reflects other factors including, but not limited to, changes in our assessment of our ability to use existing NOLs, changes in currency rates and adjustments to reflect differences between the actual returns filed and the
estimates we made at financial reporting dates. For 2009, we have reviewed the NOL carryforwards for each of our entities to determine if it is more likely than not that the NOL carryforward would be utilized in future years. Based on our review, we
have reduced income tax expense and the valuation reserve in 2009 by $167, related to the NOL carryforward for VDS Austria . The company expects to generate adequate taxable income to realize deferred tax assets in foreign jurisdictions where no
valuation reserve exists.

The company has not provided deferred U.S. taxes on its unremitted foreign earnings because it
considers them to be permanently invested. The unremitted foreign earnings are estimated to be $64,000. We have provided a deferred tax liability of $194 to reflect the foreign tax liability on unremitted earnings to one of our foreign subsidiaries.

We had no accrued interest or penalties for income tax liabilities at December 31, 2009. Our policy is to record
interest expense and penalties on income taxes as income tax expense.

ASC 740-10 sets a more likely than not
criterion for recognizing the tax benefit of uncertain tax positions; it established measurement criteria for tax benefits and it established certain new disclosure requirements. We have identified one such exposure concerning cost allocations
related to the implementation of our worldwide strategy related to the ownership of our intellectual property for which we had a $475 reserve at December 31, 2008, which is an offset to our U.S. deferred tax asset. This reserve was reduced to
$470 at December 31, 2009.

Note 6  Deferred Warranty Revenue and
Warranty Reserve

Our standard practice is to provide a warranty on our DIGIPASS hardware for either one or two years,
depending on where the sale is made, after the date of purchase. Customers may purchase extended warranties covering periods from one to four years after the standard warranty period. We defer the revenue associated with the extended warranty and
recognize it into income on a straight-line basis over the extended warranty period. The estimated cost of providing warranty services during the extended warranty period will be less than the revenue related to such warranty service.

Deferred warranty revenue at December 31, 2009, which will be recognized as revenue as follows:

warranty claims related to products sold and recognized in revenue. The reserve is included in accrued expenses. Activity in the claims reserve account during the three fiscal years ended December 31 was as follows:

of our Belgian subsidiarys defined accounts receivable up to a maximum of 5,000 Euros. Borrowing under the line of credit may be denominated in Euros, U.S. Dollars or Swiss Francs. If the
borrowings are denominated in Euros, we are obligated to pay interest at the monthly average of the EONIA (Euro Over Night Index Average) plus 2.5% per year. If the borrowings are denominated in U.S. Dollars, we are obligated to pay interest at
the U.S. Dollar Fed Fund Rate plus 2.5% per year. If the borrowings are denominated in Swiss Francs, we are obligated to pay interest at the Swiss National Repo Rate plus 2.5% per year. Either party can terminate the credit line with

insolvent, cease operations or experience a change in control.

In 2009 and 2008, we did not borrow against the line of
credit. Interest expense related to debt was $284 for the year ended December 31, 2007.

Note 9  Stock Compensation Plans

In June 2009, our stockholders approved the VASCO Data Security, International, Inc. 2009 Equity Incentive Plan (the 2009 Equity
Plan). The 2009 Equity Plan permits the issuance of awards in a variety of forms, including (1) shares of our common stock, (2) nonqualified and incentive stock options for the purchase of our common stock, (3) stock
appreciation rights, (4) deferred stock, (5) other stock-based awards (including restricted shares, performance shares, performance units and other stock unit awards), and (6) cash incentive awards. No awards had been made under the
2009 Equity Plan as of December 31, 2009. Upon our stockholders approval of the 2009 Equity Plan, our 1997 Stock Compensation Plan, as amended and restated in 1999 (the 1997 Compensation Plan) was suspended and no additional
awards will be issued under the 1997 Compensation Plan. However, all outstanding awards under the 1997 Compensation Plan were unaffected by our stockholders approval of the 2009 Equity Plan.

Our 1997 Compensation Plan was designed and intended to provide performance incentives to employees and non-employee directors, consultants
and other key persons of the company. The 1997 Compensation Plan was administered by the Compensation Committee as appointed by the Board of Directors.

The 1997 Compensation Plan permitted the award of stock compensation in various forms
including, but not limited to stock options, restricted stock, and other stock-based awards and was intended to be a nonqualified plan.

As of December 31, 2009, the number of shares allowed to be issued under the 2009 Equity Plan was 8,000 shares of the companys common stock, representing 21.3% of the issued and outstanding
shares of the company as of such date.

The following table summarizes compensation expense recorded under the 1997
Compensation Plan. No tax benefits were recognized, due to our fully reserved U.S. NOL carryforwards.

Stock Options

We have not granted stock options since 2005; however, compensation expense is recognized for the unvested options as required by the ASC
718-10. This statement requires the company to estimate the fair value of stock options granted and to record compensation expense equal to the estimated fair value. The fair value of stock options at the date of grant is estimated using the
Black-Scholes option pricing model, with the expected life adjusted to reflect the effect of post-vesting restrictions. This compensation expense is recorded on a straight-line basis over the vesting period of the options.

All options granted under the 1997 Compensation Plan were issued at market value on the date of grant, with terms of six to ten years and
vesting periods ranging from one to five years. The company may issue new shares or treasury shares for option exercises. The following table summarizes option activity for the year ended December 31, 2009. All options outstanding at
December 31, 2009 were fully vested.

Time-Based Restricted Stock

We granted restricted stock awards to employees and non-employee directors under the 1997 Compensation Plan. Awards to non-employee directors vest on the first anniversary date of the grant and awards to
employees vest annually over a four year period. These shares are subject to forfeiture if the service period requirement is not met. Compensation expense equal to the market value of the stock on the grant date is recorded on a straight-line basis
over the vesting period as required ASC 718-10. Compensation expense for 2009 was $961. The following table summarizes the time-based restricted stock activity for the year ended December 31, 2009:

The unamortized future compensation expense for the time-based restricted stock awards was $840 at
December 31, 2009.

Performance-Based Restricted Stock

Performance-based restricted stock was granted under the 1997 Compensation Plan and is earned over a three-year period beginning
January 1 of the year of grant. Each executive officers right to performance-based restricted shares is subject to VASCOs achievement of a cumulative earnings per share goal for the following three years. Each executive officer will
receive 0% of the shares if less than 80% of the performance goal is achieved, 50% of the shares if 80% of the performance goal is achieved, 100% of the shares if 100% of the performance goal is achieved, and 125% of the shares if 140% of the
performance goal is achieved.

The performance-based restricted shares granted in 2007 lapsed unearned as VASCO did not
achieve the cumulative earnings per share goal for the three years ending December 31, 2009. The number of shares granted

was 83 in 2009 and 29 in 2008, which represents the number of shares that will be received if the Company achieves 100% of the performance goal. The shares received for performance at a level
between stated performance percentages will be interpolated. The performance targets are established by the Board of Directors.

Compensation expense equal to the market value of the stock on the grant date is recorded on a straight-line basis over the vesting period if the performance condition is deemed to be probable, as required by ASC 718-10. Compensation
expense in 2009 includes a benefit of $650 for the reversal of 2007 and 2008 award accruals and expense of $231 for the 2009 awards. The unamortized future compensation expense for the performance-based restricted stock was $477 at December 31,
2009.

Long-term Incentive Compensation

Under the 1997 Compensation Plan, we provided long-term incentive awards to key employees, other than named executive officers, that can be
earned if the company achieves certain cumulative earnings per share targets over a three year period. The amount of payment will be determined as follows: no award will be paid if the cumulative earnings per share is less than 90% of the target; if
the cumulative earnings per share is greater than 90% but less than 110% of the target, the award will be prorated on a basis consistent with actual performance; and if the cumulative earnings per share is greater than 110% of the target, 120% of
the award will be paid.

The award amounts are designated as a specific dollar amount but, at the option of the company, can
be paid in either VASCO common stock or cash. If paid in stock, the company will issue the corresponding number of freely tradable shares to the employees based on the stock price on the date the awards are earned. The company granted awards
totaling $1,968, $1,980, and $1,440 in 2009, 2008 and 2007, respectively. Compensation expense for long-term incentive awards is recognized ratably over the period beginning with the effective date of the grant and ending on December 31 of the
targeted three-year period, if it is deemed probable that the target will be met. Accruals for the 2007 and 2008 grants were reversed in the first quarter of 2009, when it became clear that the performance targets were not likely to be met.
Compensation expense in 2009 includes a benefit of $1,352 for the 2007 and 2008 reversals and expense of $490 for the 2009 award. Employees forfeit their awards if they terminate from the company prior to the end of the three-year target period. The
amounts expensed are reported as liabilities on the balance sheet. The unamortized future compensation expense for the long-term incentive awards was $1,478 at December 31, 2009.

Note 10  Earnings 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. A reconciliation of
the shares included in the basic and fully diluted earnings per share calculations is as follows:

Note 11  Employee Benefit
Plan

We maintain a defined contribution pension plan for our U.S. employees established pursuant to the provisions of
Section 401(k) of the Internal Revenue Code, which provides benefits for eligible employees of the company and allow us to match employee contributions. For the years ended December 31, 2009, 2008 and 2007, we contributed $75, $100 and
$72, respectively, to this plan as matching contributions.

We also maintain a pension plan for our Belgian employees, in
compliance with Belgian law. The plan is a defined contribution plan, but has a minimum return guarantee under Belgian law. Returns guaranteed by the pension plan administrator are essentially equal to the legal requirement. For the years ended
December 31, 2009, 2008 and 2007, the company contributed $487, $386 and $288, respectively, to this plan.

From time to time, we have been involved in litigation incidental to the conduct of our
business. Currently, we are not a party to any lawsuit or proceeding that, in managements opinion, is likely to have a material adverse effect on its business, financial condition or results of operations.

Note 14  Quarterly Results of Operations (unaudited)

The fourth quarter of 2009 net income includes an adjustment to reduce prior quarters income tax expense by $633. Income tax expense recorded for the nine months ended September 30, 2009 was
based on an estimated annual effective tax rate of 29%. The actual tax rate for 2009 was 22.6%.

In the fourth quarter of
2008, we recorded an impairment charge of $1,276 to cost of goods sold related to a product development project for a potential future customer where the carrying value was not recoverable. In the fourth quarter of 2008, we also reduced the
valuation reserve of the deferred tax asset for the NOL carryforwards for our foreign subsidiaries. The valuation reserve adjustment decreased our tax expense by $782. The quarterly results of operations are as follows:
