ITEM 1 - BUSINESS VASCO Data Security International, Inc. was incorporated in the state of Delaware in 1997 and is the successor to VASCO Corp., a Delaware corporation. Our principal executive offices are located at 1901 South Meyers Road, Suite 210, Oakbrook Terrace, Illinois 60181 and the telephone number at that address is (630) 932-8844. Our principal offices in Europe are located at Koningin Astridlaan 164, B-1780 Wemmel (Belgium) and the telephone number at that address is 32(0)2/456.98.10. Unless otherwise noted, references in this Annual Report on Form 10-K to "VASCO," "Company," "company, " "we," "our," and "us" refer to VASCO Data Security International, Inc. and its subsidiaries. Additional information on the Company, its products and its results may be found on the Company's web site at www.vasco.com. 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" products 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, Our Digipass devices, most of which incorporate an electronic signature capability, guarantee the integrity of electronic transactions and data transmissions. Some of our Digipass units are compliant with the Europay MasterCard Visa ("EMV") standard and are compatible with MasterCard's and VISA's new smart cards. The backbone of our product range is VACMAN Controller. VACMAN Controller is being extended to support all authentication technologies, including passwords, dynamic password technology (Digipass), certificates and biometrics, on one unique platform. Our strategy is to become the full option, all-terrain authentication company. For user access control, our VACMAN Middleware products limit application access to designated Digipass users. Digipass and VACMAN combine to provide greater flexibility and a more affordable means than competing products of authenticating to any network, including the Internet. - ---------- 3

Our target markets are the applications and their several hundred million users that utilize fixed passwords as security. Our time-based system generates a "one-time" password that changes with every use. As a result, when compared to fixed passwords, it substantially reduces the risk of unauthorized access to the application. As of December 31, 2005, we had shipped approximately 20 million Digipass units since our inception. Our security solutions are sold worldwide through our direct sales force, as well as through distributors, resellers and systems integrators. We currently have more than 2,300 customers in more than 100 countries. Representative customers of our products include HSBC, Rabobank Nederland, ING Bank, Fortis Bank, Wachovia, Daimler Chrysler, Volvo and CoStar Group. In 2004, we sold to 543 new accounts of which 70 were banks and 473 were corporate network access customers. For full year 2005, we sold 821 new accounts including 89 new banks and 732 new Corporate Network Access accounts. 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 Data Security, Inc. in 1993. In 1996, we began an expansion of our computer security business by acquiring Lintel Security NV/SA, a Belgian corporation, 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 five acquisitions and one disposition. In May 1999, we acquired the assets of SecureWare SA, a French company, for a combination of our stock and cash totaling approximately $1.4 million. In October 1999, we acquired Intellisoft Corp. for stock and cash totaling approximately $8 million with the cash being distributed to dissenting shareholders. In August 2000, we acquired Invincible Data Systems (IDS) for a total of 322,565 shares of common stock. We acquired Identikey Ltd. ("Identikey") in March 2001, a privately held international security software company headquartered in Brisbane, Australia. Under the terms of the purchase agreement, more than 90 percent of the outstanding capital stock of Identikey was exchanged for 366,913 shares of common stock. The remaining 10% of Identikey has been acquired at various times with the final purchase completed in January 2003 in exchange for 126,426 shares of common stock and $23,362 in cash. In July 2003, we sold our interest in the VACMAN Enterprise business unit, which assets were acquired in the Intellisoft transaction, to SecureD Services, Inc. ("SSI"). Under the terms of the agreement, we received a senior secured promissory note with a face value of approximately $1.1 million, valued at $1.0 million, and Convertible Preferred Stock from SSI, valued at $0.6 million, in exchange for the VACMAN Enterprise assets. The promissory note bears a 6% interest rate and is payable in 36 equal and consecutive monthly payments. The Preferred Stock includes a 6% cumulative stock dividend, payable quarterly, and can be converted into SSI's common stock at defined intervals beginning July 1, 2005. In accordance with Statement of Financial Accounting Standard (SFAS) No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets," the assets and liabilities of this business unit have been disaggregated from our operational assets and liabilities and have been reported as results of discontinued operations. Prior periods have been restated to conform to this presentation. On February 4, 2005, pursuant to a share sale and purchase agreement by and among us, A.O.S. Holding B.V., Filipan Beheer B.V., Mr. Mladen Filipan and Pijnenburg Beheer N.V., we completed our acquisition of 100% of the total issued share capital of A.O.S. Hagenuk B.V., a private limited liability company organized and existing under the laws of the Netherlands. The base purchase price was EUR 5 million of which EUR 3.75 million was paid in cash and the remainder was paid in shares of our Common Stock. 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 4

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 the home and office settings, combined with widespread access to the Internet, have created significant opportunities for electronic commerce by individual users such as electronic bill payment, home banking and home shopping. Fueled by 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. Many banks in European countries began to issue smart cards (credit cards with a micro-chip) that are compliant with the EMV standard in 2005. Worldwide, more governments are issuing guidance for online banking security. For example, the Hong Kong Monetary Authority (HKMA), the Hong Kong Association of Banks (HKAB) and the Hong Kong Police Force (HKPF) jointly issued the following statement regarding the use of two-factor authentication for Internet banking: "In view of the increasing acceptance of Internet banking services and the growing sophistication of Internet banking frauds, the banking industry in Hong Kong reached a general consensus in June 2004 to implement two-factor authentication for high-risk retail Internet banking transactions. Banks offering high-risk retail Internet banking transactions will have two-factor authentication ready for their customers by June 2005. Customers will need to adopt two-factor authentication if they wish to conduct those transactions." In October 2005, in the U. S., the Federal Financial Institutions Examination Council (FFIEC) issued guidance for Strong Authentication/Two Factor Authentication in the Internet banking environment. Financial institutions are expected to achieve compliance by year-end 2006. 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. 5

- 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 with 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 lower total cost of security ownership than competing products and services. We have found that product improvements and tools that lower a customer's total cost of ownership create differentiating sales and marketing tools and also help in the development of a highly loyal customer base that is open to new solutions that we offer. As a result of this approach, we believe that we are positioned to be the leading provider of strong software and hardware authentication security solutions for all types of on-line, risk-based transactions. OUR STRATEGY We believe we have one of the most complete lines of security products and services for Strong User Authentication available in the market today and we also believe that we are the a leading worldwide provider of these products and services. A key element of our growth strategy is to demonstrate to an increasing number of distributors, resellers and systems integrators that, by incorporating our security products into their own products, they can more effectively differentiate themselves in their marketplaces and increase the value of their products. In addition, we will demonstrate to our corporate users that our products provide mission critical security to their internal and external security infrastructures. Following this active marketing and promotion effort, we will work with these resellers and integrators to support their sales of solutions that include our products. Also, we plan to expand our direct sales marketing program to new and existing blue chip customers. Further, we intend to: Increase Sales and Marketing Efforts Worldwide. We intend to increase sales of our security products and services in our established European markets and to actively increase our sales and support presence and marketing efforts in North America, South America, Asia/Pacific, Australia and the Middle East. We plan to: 6

- Make VASCO the full option, all-terrain authentication company by offering our customers a solution with VACMAN Controller as the core and the backbone, encompassing all four authentication technologies (passwords, dynamic password technologies, certificates and biometrics); - Market new services and products to our existing customers by providing testimonial evidence of user experiences from other customers; - Maintain a marketing campaign in Europe, the Middle East, North America and Asia to raise awareness of our solutions among the distributors and resellers of popular third party software products and to establish relationships with them whereby they become resellers of our products and solutions; - 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, in new markets. Continue Innovation. We intend to continue to enhance and broaden our line of security products to meet the changing needs of our existing and potential customers by: - Building on our core software and hardware security expertise, such as expanding our technology for use on different platforms (like mobile phones and personal digital assistants); - Acquiring complementary technologies or businesses; and - Developing additional applications for our products in areas that may include securing the exchange of data in the business-to-business field and providing security for Internet gambling and lottery transactions, among others. OUR PRODUCTS Digipass Product Line Our Digipass product line, which exists as a family of authentication devices as well as extensive software libraries, provides a flexible and affordable means of authenticating users to any network, including the Internet. Security can be broken into three factors: - What the user has (the Digipass device itself); - What the user knows (the PIN code to activate the Digipass); and - Who the user is (biometrics). 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: - Hardware device (the token) itself so that if he or she does not physically have the token, he or she will not be able to log on to the system; and - PIN code for the token so if the user does not know the appropriate code, he or she will not be able to use the applications stored inside. Both of these factors help to make sure that a natural person is authenticating (or signing), instead of a computer or another device. These factors also enable very high portability for security anytime, anywhere and anyhow. Digipasses calculate dynamic passwords, also known as one-time passwords, to authenticate users on a computer network and for a variety of other applications. There are several 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 7

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. In addition, 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, Digipass's Authentication Server generates one-time passwords that are sent to the mobile telephone user by SMS (Short Messaging System). Digipass technology combines the benefits of traditional password tokens (authentication and digital signatures) with smart card readers. Together, they bring portability to smart cards and allow secure time-based algorithms. A VASCO-secured system has the features needed to secure both today's and tomorrow's IT resources. 8

DIGIPASS AT WORK (IMAGE 1) (IMAGE 2) (IMAGE 3) (IMAGE 4) (IMAGE 5) The above illustration shows the various steps in the Digipass authentication process. In the first step, the devices are initialized with their unique set of secrets and keys per device. These secrets are stored in an encrypted way on a compact disk or diskette that is sent to the application owner (for example, the information technology manager in an organization or the security department of a bank). These compact disks or diskettes are one way of safely transporting the Digipass secrets to the host computer. The files on CD, Memory Stick or diskettes will be used to read all the necessary secrets and other data from the delivered Digipasses into a database. Then the application owner will assign the Digipass units to the end-users. This assignment is based on the serial number of the Digipass and the identity of the end-user. The Digipass is then shipped to the end-user along with a user manual. The protected PIN-code is sent to the end user in a separate shipment on a secure PIN-mailer. Using a Digipass requires a connection to the host (server) computer that knows the parameters of the end-user's Digipass. Every time the user sends a dynamic password or digital signature to the host computer, the computer will retrieve all the necessary information from the database and will check the validity of the password or signature. After the host has checked the validity of the dynamic password or signature, it will notify the end-user of the correctness or incorrectness of the validity check. Digipass security devices are not terminal dependent and do not require any specific software platform since they only interact with a person. 9

Currently, the Digipass is 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 the Digipass is to secure access to corporate networks for home-based, traveling and other remote users. Finally, Digipasses are increasingly being used in a variety of e-commerce applications where the user is part of a pre-defined user group. We intend to expand the use of the Digipass to other groups of users and applications, including electronic commerce transactions directed at the general public. Digipass Pack Digipass Pack is a bundling of VASCO Digipass Go 1 or Go 3 tokens and VACMAN Middleware, offering strong identity authentication to Small and Medium Sized Enterprises ("SME"s). Although the packs contain standard Digipass Go 1/Go 3 tokens; combinations with other Digipass models are possible. Digipass Pack is compliant with server security products of VASCO Solution Partners, like CITRIX, Netscreen, Check Point, and CISCO and is marketed via VASCO's regional channel partners (Distributors). (IMAGE 6) 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. Designed to provide the greatest flexibility, while not 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 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. The user simply adds a field to his or her existing user database, describing the unique Digipass token assigned to the user. VACMAN Controller takes it from there, automatically authenticating the logon 10

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 VACMAN Middleware brings strong user authentication to existing RADIUS-based environments, while seamlessly integrating with other current infrastructure technology. Many companies already use RADIUS servers and/or firewalls to provide a way to centrally manage all remote connections to the corporate IT infrastructure. VACMAN Middleware allows administrators to positively identify remote users before granting remote access to sensitive corporate data and applications. Logically, VACMAN Middleware is installed between the RADIUS client (NAS, RAS or firewall) and the existing RADIUS server or servers. Once installed, VACMAN Middleware functions transparently, adding strong, two-factor, authentication without otherwise affecting the operation of the server or other network components. With a range of automated administration features such as Dynamic User Registration, automatic assignment of Digipass devices and the ability to bulk manage users, VACMAN Middleware provides transparent strong authentication without adding significantly to the administration load. 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 certain European countries, which cover multiple aspects of our technology. The majority of our patents cover our Digipass family. These patents expire between 2006 and 2022, with one patent expiring in 2006. In addition to the issued patents, we also have several patents pending in the U. S. and other countries. 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. PRODUCTION Our security hardware products are manufactured by third parties pursuant to purchase orders that we issue. Our hardware products are made primarily from commercially available electronic components that are purchased globally. Our software products are produced either in-house or by several outside sources primarily in Australia and Europe. The security tokens 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 France. The microprocessors are the only components of our security tokens 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 11

our inventory are typically required to be placed with more than 12 weeks of lead-time, allowing us to attempt to make appropriate arrangements with our suppliers. We purchase the microprocessors and arrange for shipment to third parties for assembly and testing in accordance with our design specifications. Our security token 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 companies such as Sony and Samsung. 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. Additional competitors are ActivIdentity, Xiring, Todos Data Systems and Kobil Systems. There are many other companies such as Secure Computing, SafeNet, Entrust, and Aladdin Knowledge Systems 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 price. Although we believe that our products currently compete favorably with respect to such factors, other than name recognition in certain markets, there can be no assurance that we can maintain our competitive position against current and potential competitors, especially those with significantly greater financial, marketing, service, support, technical and other competitive resources. 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, VASCO has, and will continue to forge its 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 distributors, resellers and systems integrators. A sales staff of 31 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 12

prepared by our support engineers that explain how we believe our security products can add value or otherwise be beneficial.

Rabobank Nederland and Fortis Bank each exceeded 10% of our revenue in 2003. 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. These seasonal trends are most notable in the summer months, particularly in Europe, when many businesses defer purchase decisions. FINANCIAL INFORMATION RELATING TO FOREIGN AND DOMESTIC OPERATIONS See Note 13 to VASCO Notes to Consolidated Financial Statements for a breakdown of revenues and long-lived assets between U.S. and foreign operations. EMPLOYEES As of December 31, 2005, we had 128 full time employees. Of these, 19 were located in North America, 85 were located in Europe, 17 were located in Australia and 7 located in Asia/Pacific. Of the total, 50 were involved in sales, marketing and customer support, 30 in operations, 31 in research and development and 17 in administration. ITEM 1A - RISK FACTORS You should carefully consider the risk factors described below and all other information contained or incorporated by reference in this Annual Report on Form 10-K before you make an investment decision. If any of the following risk factors, as well as other risks or uncertainties that are not currently known to us or that we currently believe are not material, actually occur, our business, financial condition and results of operations could 13

be materially and adversely affected. In that case, the trading price of our Common Stock could decline and you may lose part or all of your investment. WE HAD A HISTORY OF OPERATING LOSSES AND HAVE A LARGE ACCUMULATED DEFICIT. Although we have reported net income of $7,701, $3,253 and $2,756 for the years ended December 31, 2005, 2004 and 2003, respectively, we have incurred significant net losses in prior years and as of December 31, 2005, our accumulated deficit is $32,985. OUR REVENUE AND CASH RECEIPTS MAY NOT BE SUFFICIENT TO MEET THE OPERATING NEEDS OF OUR BUSINESS. 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 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 revenues 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 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, ActivIdentity, Xiring, 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. TECHNOLOGICAL CHANGES OCCUR RAPIDLY IN OUR INDUSTRY AND OUR DEVELOPMENT OF NEW PRODUCTS IS CRITICAL TO MAINTAIN OUR REVENUES. 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. 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 three to six months and with larger Banking transactions up to eighteen months. Purchasing decisions for our products and systems may be subject to delay 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. WE HAVE A SIGNIFICANT DEPENDENCE ON MAJOR CUSTOMERS AND LOSING ANY OF THESE CUSTOMERS COULD RESULT IN A SIGNIFICANT LOSS IN REVENUES. 14

If we don't find other customers who generate significant future revenues, 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 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 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 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. 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 U. S. 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 revenues. 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 REVENUES. Our business internationally is subject to a number of risks any or all of which could result in a disruption in our business and a decrease in our revenues. These include: - Inconsistent regulations and unexpected changes in regulatory requirements; - Difficulties and costs of staffing and managing international operations; - Potentially adverse tax consequences; - Wage and price controls; - Uncertain protection for intellectual property rights; - Imposition of trade barriers; - Differing technology standards; - Uncertain demand for electronic commerce; - Linguistic and cultural differences; - Political instability; and - Social unrest. 15

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 U. S., 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 European 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 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 either 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 security tokens 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 U. S. that are adverse to trade, including enactment of protectionist legislation. 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 U. S. and in some European countries, which cover multiple aspects of our technology. The majority of our patents cover the Digipass product line. These patents expire between 2006 and 2022, with one patent expiring in 2006. In addition to the issued patents, we also have several patents pending in the U. S. 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 16

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 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 do not presently maintain product liability insurance for these types of claims. 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 REVENUES. 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 revenues 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 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. 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. WE EXPERIENCE VARIATIONS IN QUARTERLY OPERATING RESULTS AND 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: 17

- The level of competition; - The size, timing, cancellation or rescheduling of significant orders; - New product announcements or introductions by current competitors; - Technological changes in the market for data security products including the adoption of new technologies and standards; - Changes in pricing by current competitors; - Our ability to develop, introduce and market new products and product enhancements on a timely basis, if at all; - Component costs and availability; - Our success in expanding our sales and marketing programs; - Market acceptance of new products and product enhancements; - Changes in foreign currency exchange rates; and - General economic trends. 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. 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 31%, with Mr. T. Kendall Hunt controlling approximately 29%, of the outstanding shares of our common stock. As the Chairman of the Board of Directors 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. OUR STOCK PRICE MAY BE VOLATILE AND YOU MAY NOT BE ABLE TO RESELL YOUR SHARES AT OR ABOVE ACCEPTABLE PRICES. 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 operating 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; - Any deviations in net revenues or in losses from levels expected by the investment community; and - Trading volume fluctuations. 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 our 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. 18

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. 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 U.S.. Several of our executives are residents of Belgium, and a substantial portion of our assets and those of some of our executives are located in Belgium. As a result, it may not be possible for investors to effect service of process on those persons located in Belgium, or to enforce judgments against some of our executives based upon the securities or other laws of jurisdictions other than Belgium. Moreover, we believe that under Belgian law there exists certain restrictions on the enforceability in Belgium in original actions, or in actions of enforcement of judgments rendered against us in courts outside jurisdictions that are a party to the Brussels Convention on Jurisdiction and the Enforcement of Judgments in Civil and Commercial Matters (as amended). Actions for enforcement of such judgments may be successful only if the Belgian court confirms the substantive correctness of the judgment of such court, and is satisfied: - That the judgment is not contrary to the principles of public policy in Belgium or rules of Belgian public law; - That the judgment did not violate the rights of the defendant; - That the judgment is final under applicable law; - That the court did not accept its jurisdiction solely on the basis of the nationality of the plaintiff; and - As to the authenticity of the text of the judgment submitted to it. Judgments rendered in the courts of parties to the Brussels Convention will be enforceable by the courts of Belgium without reexamination of the merits of the case provided such judgment is final and otherwise satisfies all of the conditions provided for in this Convention. If proceedings have been brought in one country, however, new proceedings in another country may be barred. ITEM 1B - UNRESOLVED STAFF COMMENTS None. ITEM 2 - PROPERTIES Our corporate office is located in the U. S. in an office complex in Oakbrook Terrace, Illinois, a suburb of Chicago. This facility is leased through May 31, 2010, and consists of approximately 5,100 square feet. Our sales office in the U. S. in located in Westborough, Massachusetts, a suburb of Boston. This facility is leased through February 28, 2009, and consists of approximately 3,900 square feet. Our European administrative, sales and marketing, research and development and support facilities are located in a suburb of Brussels, Belgium. These facilities consist of approximately 29,600 square feet of office space that are occupied under a lease expiring on September 30, 2011. Our Netherlands sales and R&D facility, approximately 6,100 square feet, is occupied under a lease expiring on December 31, 2010. We have two offices located in Australia. One office is located in a suburb of Brisbane, consisting of approximately 3,600 square feet under a lease expiring on January 3, 2010. The second office, which is a sales office, is located in Sydney, consisting of approximately 700 square feet under a lease expiring on October 3, 2007. 19

We have two sales offices in the Asia/Pacific region. One sales office is located in an office complex in Singapore, consisting of approximately 3,300 square feet under a lease expiring on October 14, 2007. The second sales office is located in Shanghai, China consisting of approximately 1,200 square feet under a lease expiring on November 30, 2006. We believe that these facilities are adequate for our present growth plans. ITEM 3 - LEGAL PROCEEDINGS We are from time to time involved in litigation incidental to the conduct of our business. We are not currently a party to any lawsuit or proceeding which, in the opinion of management, is likely to have a material adverse effect on our business, financial condition or results of operations. ITEM 4 - SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS No matter was submitted to a vote of security holders during the fourth quarter of 2005, through solicitation of proxies or otherwise. PART II ITEM 5 - MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Market Information On March 20, 1998, the Company's Common Stock was approved for trading on the NASD Electronic Bulletin Board system under the symbol "VDSI." On April 7, 2000, the Common Stock was listed on the Nasdaq National Market in the U. S. under the trading symbol "VDSI." In February 2003, the Common Stock was moved from the Nasdaq National Market to the Nasdaq SmallCap Market and continued trading under the symbol "VDSI." On July 15, 2003, the Company issued 2 million shares of its Common Stock to Ubizen N.V. as part of the consideration given in exchange for all of the Company's Series C Convertible Preferred Stock and Purchase Warrants owned by Ubizen. On September 11, 2003, the Company sold 800 shares, with a stated value of $10,000 per share, of its Series D 5% Cumulative Convertible Voting Preferred Stock and 600,000 warrants to purchase Common Stock to various accredited investors. The Series D Preferred was convertible into 4,000,000 shares of Common Stock. The warrants have an exercise price of $3.47 per share. The proceeds from the sale, $8,000,000 gross and approximately $7,260,000 net, were used for general corporate purposes. The Series D Stock was convertible into Common Stock at any time and the warrants can be exercised at any time from the date of issue until September 10, 2008, at which time the warrants expire. As of February 28, 2005, all of the Series D Preferred stock had been converted to Common Stock. There were 136,250 warrants outstanding at February 28, 2006. The following table sets forth the high and low closing bid quotations for the Common Stock for the periods indicated. 20

HIGH LOW ------ ----- 2006 First Quarter (through February 28, 2006) $11.44 $9.20 2005 Fourth Quarter $12.48 $7.72 Third Quarter 12.05 8.59 Second Quarter 11.45 6.00 First Quarter 9.14 5.50 2004 Fourth Quarter $ 6.92 $2.17 Third Quarter 2.55 1.81 Second Quarter 3.38 1.92 First Quarter 2.99 1.83 Holders and Dividends On February 28, 2006, the closing sale price for the Common Stock on the Nasdaq was $9.99 per share. Such market quotations reflect inter-dealer prices, without retail mark-up, markdown or commission and may not necessarily represent an actual transaction. On February 28, 2006, there were approximately 2,400 holders of record of the Common Stock. The Company has not paid any dividends on its Common Stock since incorporation. Restrictions or limitations on the payment of dividends may be imposed under the terms of credit agreements or other contractual obligations of the Company. In the absence of such restrictions or limitations, the declaration and payment of dividends will be at the sole discretion of the Board of Directors and subject to certain limitations under the General Corporation Law of the State of Delaware. The timing, amount and form of dividends, if any, will depend, among other things, on the Company's results of operations, financial condition, cash requirements, plans for expansion and other factors deemed relevant by the Board of Directors. The Company intends to retain any future earnings for use in its business and therefore does not anticipate paying any cash dividends in the foreseeable future. See Item 12 for a description of securities authorized for issuance under our equity compensation plan. Recent Sales of Unregistered Securities None Issuer Purchases of Equity Securities None. 21

ITEM 7 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (IN THOUSANDS, EXCEPT SHARE COUNT, HEAD COUNT AND UNIT PRICE DATA) OVERVIEW The following discussion is based upon our consolidated results of operations for the years ended December 31, 2005, 2004 and 2003 (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 identity authentication products that reduce the risk of loss from unauthorized transactions by validating a person's identity using a one-time password and obtaining a legally-enforceable digital signature, if needed, for financial transactions. Our products are used currently in a wide variety of applications including, but not limited to, Internet banking, Internet brokerage, e-commerce applications dealing with web or mobile access and various corporate network access applications. 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, the banks' retail customers. Our target market is any business process that uses some form of electronic interface 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. Economic Conditions: Our revenues may vary significantly with changes in the economic conditions in the countries in which we sell products currently. With our current concentration of revenues 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 revenues. During difficult economic periods, our customers often delay the rollout of existing applications and defer purchase decisions related to the implementation of our product in new applications. Currency Fluctuations. In 2005, approximately 93% of our revenue and approximately 74% of our operating expenses were generated/incurred outside of the U. S.. In 2004, approximately 90% of our revenue and approximately 79% of our operating expenses were generated/incurred outside of the U. S.. As a result, changes in currency, 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. In addition, we also attempt to minimize transaction gains and losses by hedging our net U.S. dollar asset exposure by borrowing U.S. dollars in foreign countries such that assets denominated in U.S. dollars are approximately equal to liabilities denominated in U.S. dollars. In 2005, the annual average exchange rate for the Euro strengthened approximately 1% and the Australian Dollar strengthened approximately 4% against the U.S. Dollar. The Euro strengthened approximately 10% and the Australian Dollar strengthened approximately 15% against the U.S. Dollar in 2004. We estimate that the strengthening of the two currencies in 2005 compared to 2004 resulted in a decrease in revenues of approximately $301 and an increase in operating expenses of approximately $112. While we expect that a strengthening of the Euro compared to the U. S. dollar would result in an increase in revenue, that was not the case in 2005. The decline in revenue in 2005, due to currency, reflects the timing of when revenue was realized and the corresponding changes in currency rates in those periods. In the fourth quarter of 2005, we realized a significant portion of our revenues 23

when the Euro was weaker than the same period in 2004. We estimate that the strengthening of the two currencies in 2004 compared to 2003 resulted in an increase in revenues of approximately $1,089 and an increase in operating expenses of approximately $1,106. Gains and losses resulting from foreign currency transactions are included in the consolidated statements of operations. Foreign exchange transaction gains aggregating $330 are included in other non-operating income (expense) for 2005. Foreign exchange transaction losses aggregating $538 are included in other non-operating income (expense) for 2004 and gains of $146 are included in other non-operating income (expense) for 2003. The financial position and the results of operations of our 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 generated a deficit of $1,218 in 2005 and a surplus and $687 in 2004 and are included as a separate component of stockholders' equity. REVENUE REVENUES BY GEOGRAPHIC REGIONS: We sell the majority of our products in European countries with significant sales in the U. S. and other countries, primarily Australia and Asia/Pacific. The breakdown of revenue in each of our major geographic areas was as follows: YEAR EUROPE UNITED STATES OTHER COUNTRIES TOTAL ---- ------- ------------- --------------- ------- Total Revenue: 2005 $39,219 $3,687 $11,673 $54,579 2004 24,245 3,105 2,543 29,893 2003 19,201 1,498 2,167 22,866 Percent of Total: 2005 72% 7% 21% 100% 2004 81% 10% 9% 100% 2003 84% 7% 9% 100% 2005 Compared to 2004 - Overview and Geographic Breakdown Total revenues in 2005 increased $24,686 or 83% over 2004. The increase was primarily attributable to an increase in the number of Digipass units sold and the acquisition of AOS-Hagenuk ("AOS"), partially offset by a decline in the average sales price per unit. Revenues from AOS were $4,542 in 2005, net of purchase price amortization costs of $421. Excluding revenue from AOS, consolidated revenue increased $20,144 or 67% from 2004. In 2005, we sold approximately 7,340 Digipass products, an increase of approximately 4,505 units, or 159%, over the 2,835 Digipass products sold in 2004. We believe that the increase in Digipass volume is attributable to the growth in our distribution channel, increased investment in sales staff and marketing programs, 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. Our strategy of being the high-volume, high-quality, low-cost producer allows us to compete effectively in both of our primary target markets, banking/finance ("Banking") and corporate network access ("CNA"). In 2005, we believe that our unit volume increased in large part due to our Banking customers' desire and need to provide two-factor authentication to its internet banking customers. We expect to see continued worldwide expansion in authentication for consumer-related applications and believe that we are well positioned to compete for that business as the market expands. The average price per unit in 2005 was $7.44 and was 29% lower than the $10.54 average price per unit in 2004. The decline in average price per unit reflects our strategy of providing volume-purchase discounts to 24

customers that place firm purchase orders for large-volume deployments and a change in mix of our business. We believe that the lower average prices are a critical element in our customers' decision to deploy our technology to their consumer-level customers. In 2005, while each of our markets grew, the growth in large-volume deployments exceeded our growth in our lower-volume, higher priced markets, such as Corporate Banking and CNA. As noted in the table above, revenues from each of our geographic regions increased. Both the absolute amount of revenue from each region and the growth over the prior year reflect, in general, the regulatory environment of the region and the customers' attitudes towards and acceptance of two-factor authentication. The growth in Europe, $14,974 or 62% over 2004, was attributable to several factors including, but not limited to, the acquisition of AOS, the maturity of our sales and distribution channels, increased investment in sales staff and marketing programs and the rollout of the new smart card standard by Europay, Mastercard, Visa ("EMV"). The growth in the U. S., $582 or 19%, was a result of increased investment in our sales staff and marketing programs. The growth in other countries, $9,130 or 359%, reflects the growth in the Asia and Central/South American markets. The growth in other countries was not only attributable to increased investment in our sales staff and marketing programs, but also to changes in regulations. In 2005, new regulations were enacted in Hong Kong. Under the new regulation, each bank that offered internet banking services was required to provide some form of two-factor authentication to its customers. 2004 Compared to 2003 - Overview and Geographic Breakdown Total revenues in 2004 increased $7,027 or 31% over 2003. The increase was attributable to an increase in both the number of Digipass units sold and an increase in the average sales price per unit. In 2004, we sold approximately 2,835 Digipass products, an increase of approximately 441 units, or 18%, over the 2,394 Digipass products sold in 2003. The average price per unit in 2004 was $10.54, which was 11% higher than the $9.53 average price per unit in 2003. The increase in units is primarily attributable to our investment in sales and marketing activities in 2004. The average sales price increased primarily as a result of broadening our customer base. As a result of adding approximately 1,100 new customers in 2003 and 2004 combined, the average sales price increased as our dependence on a few major customers decreased. The new customers added in 2004 were ordering smaller quantities at higher average prices as compared to the existing major customers. 25

REVENUES BY TARGET MARKET: Revenues are generated currently from two primary markets, Banking and CNA through the use of both direct and indirect sales channels. The breakdown of revenue between the two primary markets is as follows: YEAR BANKING CNA TOTAL ---- ------- ------ ------- Total Revenue: 2005 $46,784 $7,795 $54,579 2004 23,977 5,916 29,893 2003 17,725 5,141 22,866 Percent of Total: 2005 86% 14% 100% 2004 80% 20% 100% 2003 78% 22% 100% Revenues from the Banking market increased $22,807 or 95% in 2005 over 2004 and revenues from the CNA market increased $1,879 or 32% in the same period. The increase in revenues in both markets is attributable, in part, to the development of the indirect sales channel, which includes distributors, resellers, and solution partners. The number of distributors increased to 45 at the end of 2005 from 39 at the end of 2004. The indirect sales channel supplements the Company's direct sales force in the Banking market and is the primary source of revenues in the CNA market. Revenues generated by AOS in 2005 are included in the Banking market. Revenues from the Banking market increased $6,252 or 35% in 2004 over 2003 and revenues from the CNA market increased $775 or 15% in the same period. The increase in revenues in both markets is attributable, in large part, to the aforementioned indirect sales channel. The amounts shown above for CNA currently include revenues generated in the e-commerce market. We expect that the e-commerce market will be an important source of future revenue for the Company as our products will not only provide a higher level of security for purchases made over the Internet, they can also help protect our customers' revenue stream by making it more difficult for subscribers to our customers' Internet services to share passwords. GROSS PROFIT AND OPERATING EXPENSES The following table sets forth, for the periods indicated, certain consolidated financial data as a percentage of revenues for the years ended December 31, 2005, 2004 and 2003. 26

PERCENTAGE OF REVENUE YEAR ENDED DECEMBER 31, ------------------------ 2005 2004 2003 (a) ----- ----- -------- Revenues 100.0% 100.0% 100.0% Cost of goods sold 36.9 30.7 39.4 ----- ----- ----- Gross profit 63.1 69.3 60.6 Operating costs: Sales and marketing 27.1 30.6 30.7 Research and development 6.6 8.2 8.5 General and administrative 8.3 10.7 14.1 Restructuring expenses (recoveries) (0.3) (0.1) -- Amortization of purchased intangible assets 1.3 1.3 2.4 ----- ----- ----- 43.0 50.7 55.7 ----- ----- ----- Operating income from continuing operations 20.1 18.6 4.9 Interest income (expense) 0.1 0.4 (0.3) Other income (expense), net 0.9 (1.8) 0.5 ----- ----- ----- Income before income taxes 21.1 17.2 5.1 Provision for income taxes 7.0 6.3 1.8 ----- ----- ----- Net income from continuing operations 14.1 10.9 3.3 ===== ===== ===== (a) Excludes results of discontinued operations. See footnote 11 to the consolidated financial statements for more detailed information regarding discontinued operations. GROSS PROFIT 2005 Compared to 2004 Consolidated gross profit for 2005 was $34,438, an increase of $13,729, or 66%, from the $20,709 reported for 2004. Gross profit as a percentage of revenue was 63% in 2005, as compared to 69% in 2004. The decrease in the gross profit as a percentage of revenue reflects the decline in average sales price per unit related to the increase in the average size of orders received partially offset by a decline in the average manufacturing cost of our product. The significant increase in the Digipass products sold in 2005 over 2004 reflected larger customer deployments in the Banking market, the results of which were reflected in an increase in the average quantity ordered and a decrease in the average sales price per unit. In 2005, the average quarterly order size for the Banking market increased 98%, from approximately 11 units to 22 units per shipment, and the average selling price per unit decreased 25%, from approximately $8.95 per unit to $6.70 per unit. We expect the Banking market to continue large deployments to its consumer Internet banking customers and, as a result, we expect that we will see additional pressure on the average selling price in 2006. During 2005, we also saw an increase in the average order size and a corresponding decrease in average selling price for customers in our CNA segment. The average selling price per Digipass product declined approximately 26% to $26.75 per unit in 2005 as compared to 2004. The average manufacturing cost per Digipass unit sold declined from approximately $3.24 to $2.74, or 15%, in 2005 as compared to 2004. The decline in the average cost per unit reflected a reduction in the manufacturing cost of almost all units as well as a change in mix of specific products sold. 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 decrease in revenue resulting from changes in currency rates of $301, as noted above, along with our cost of goods sold being denominated in U.S. dollars resulted in a decrease in the gross profit rate of approximately 0.2 percentage points. 2004 Compared to 2003 27

Consolidated gross profit for the year ended December 31, 2004 was $20,709, an increase of $6,853, or 49%, from $13,856 reported the year ended December 31, 2003. Gross profit as a percentage of revenue was 69% in 2004, as compared to 61% in 2003. The increase in the gross profit as a percentage of revenue reflects the change in mix of orders within the banking market, the reduction in the average cost of each Digipass unit sold and the beneficial impact of currency. The change in mix within the banking market reflected the impact of new customers added in 2004 and 2003 and resulted in a reduction in the average quantity ordered and an increase in the average sales price per unit. In 2004, the average quarterly order size for the banking market decreased 35%, from approximately 17 units to 11 units, and the average selling price per unit increased 9%, from approximately $8.20 per unit to $8.95 per unit. New banking customers generally order smaller quantities at the beginning of the relationship as they implement pilot programs and, later, increase their orders as they roll the program out to their broader customer base. Orders for smaller quantities have higher sales prices and higher gross margins. The average manufacturing cost per Digipass unit sold declined approximately 18% in 2004 as compared to 2003. The decline in the average cost per unit reflected a reduction in the manufacturing cost of most all units as well as a change in mix of specific products sold. Our purchases of inventory are denominated in U.S. dollars. Also, as previously noted, we also denominates a portion of its sales in Euros in order to offset the effects of currency on operating expenses. As the Euro and Australian dollars strengthened during the year, revenues from sales made in Euros and Australian Dollars increased, as measured in U.S. dollars, without the corresponding increase in cost of goods sold. The benefit from changes in currency rates as noted above was approximately $1,089 and represents an improvement in the gross profit rate of approximately 1.2 percentage points. SALES AND MARKETING EXPENSES 2005 Compared to 2004 Consolidated sales and marketing expenses for the year ended December 31, 2005 were $14,784, an increase of $5,624, or 61%, from the $9,160 reported for 2004. Expenses in 2005 included approximately $841 of expense related to AOS. Excluding AOS, sales and marketing expenses increased approximately $4,783 or 52% from 2004. The increase was primarily due to an increase in average headcount and related compensation expenses, an increase in marketing programs and materials, an increase in travel, an increase in commissions paid to third-party agents and redundancy costs associated with the termination of a small group of employees. The average full-time sales, marketing and operations employee headcount increased 42% to 71 in 2005 from 50 in 2004. At year-end 2005, the Company employed 80 full-time sales, marketing and operations employees, reflecting its increased investment in an effort to accelerate its sales growth. The change in currency rates in 2005 did not have a significant impact on the comparison of sales and marketing expenses in 2005 to 2004. 2004 Compared to 2003 Consolidated sales and marketing expenses for the year ended December 31, 2004 were $9,160, an increase of $2,132, or 30%, from the 7,028 reported for 2003. The stronger Euro increased sales and marketing expense approximately $729 in 2004. Excluding the impact of changes in exchange rates, sales and marketing expenses increased approximately $1,403 or 20% from 2003. The increase, excluding currency, was primarily due to an increase in average headcount and related compensation expenses, an increase in marketing programs and materials, and an increase in travel. The average full-time sales and marketing employee headcount increased 6% to 50 in 2004 from 47 in 2003. At year-end 2004, the we employed 61 full-time sales and marketing employees, reflecting its increased investment in an effort to accelerate its sales growth. RESEARCH AND DEVELOPMENT EXPENSES 28

2005 Compared to 2004 Consolidated research and development costs for the year ended December 31, 2005 were $3,579, an increase of $1,138, or 47%, from the $2,441 reported for 2004. Expenses in 2005 included approximately $802 of expense related to AOS. Excluding AOS, research and development expenses increased approximately $336 or 14% from 2004. The increase primarily reflects higher compensation-related expense. Average full-time research and development employee headcount in 2005 was 27 compared to 18 in 2004. The change in currency rates in 2005 did not have a significant impact on the comparison of research and development expenses in 2005 to 2004. 2004 Compared to 2003 Consolidated research and development costs for the year ended December 31, 2004 were $2,441, an increase of $486, or 25%, from the $1,955 reported for 2003. The stronger Euro and Australia Dollar increased research and development expenses approximately $255 in 2004. Excluding the impact of changes in exchange rates, research and development expenses increased approximately $231 or 12% from 2003. The increase primarily reflects higher compensation-related expense. Average full-time research and development employee headcount in 2004 was 18 compared to 17 in 2003. GENERAL AND ADMINISTRATIVE EXPENSES 2005 Compared to 2004 Consolidated general and administrative expenses for the year ended December 31, 2005 were $4,556, an increase of $1,365 or 43%, from the $3,191 reported for 2004. Expenses in 2005 included approximately $269 of expense related to AOS. Excluding AOS, general and administrative expenses increased approximately $1,096 or 34% from 2004. The increase was primarily due to increased cost of professional services, an increase in average headcount and related compensation expenses and an increase in the provision for uncollectible accounts. The increase in professional services was primarily related to the cost of performing management's assessment of internal controls over financial reporting, the increased cost of the integrated audit and legal services related to tax planning initiatives. The average full-time general and administrative employee headcount increased 27% to 14 in 2005 from 11 in 2004. The change in currency rates in 2005 did not have a significant impact on the comparison of general and administrative expenses in 2005 to 2004. 2004 Compared to 2003 Consolidated general and administrative expenses for the year ended December 31, 2004 were $3,191, a decrease of $20, or 1%, from the $3,211 reported for 2003. The stronger Euro increased general and administrative expense approximately $123 in 2004. Excluding the impact of changes in exchange rates, general and administrative expenses decreased approximately $143 or 4% from 2003. This decrease can be principally attributed to reduced spending on legal and other professional services, the collection of cash on accounts upon which a reserve had been established in prior years, and a reduction in depreciation expenses which was partially offset by increased compensation-related expenses. Average full-time general and administrative employee headcount in 2004 was 11 compared to 10 in 2003. RESTRUCTURING EXPENSES 2005 Compared to 2004 29

During the fourth quarter of 2002, we recorded restructuring charges of $319 related to operations in France and excess space in our U.S. headquarters. In 2005, we resolved all issues associated with the closure of the French operation and reversed reserves that were no longer needed, some of which had been recorded prior to the decision to close the operation, resulting in a gain of $172. 2004 Compared to 2003 In 2004, we reversed $32 of the restructuring reserve that had been established in prior years. The adjustment was a result of renegotiating the U. S. headquarters lease in 2004. AMORTIZATION EXPENSE 2005 Compared to 2004 Amortization expense for 2005 was $738, an increase of $341 or 86% over the 2004 amount. The increase was due to the amortization of a $367 intangible asset for purchase orders acquired as part of the AOS-Hagenuk acquisition in February, 2005. 2004 Compared to 2003 Amortization expense for 2004 was $397, a decrease of $142 or 26% from the 2003 amount. This reduction reflects lower amortization of capitalized technology, partly offset by the effect of exchange rates. INTEREST INCOME (EXPENSE), NET 2005 Compared to 2004 Consolidated net interest income (expense) was income of $69 in 2005 compared to income of $120 in 2004. The reduction in income reflected the cost of borrowings related to our foreign currency hedging program, lower interest earned on the installment note it received as a result of its sale of the VACMAN Enterprise business in 2003, partially offset by interest earned on an increase in average net cash balances that resulted from our strong operating cash flow throughout 2005. Average net cash balances were $9,200 in 2005, an increase of $2,700 or 42% from $6,500 in 2004. Our bank borrowings are solely related to our foreign currency hedging program. We invested its cash balances in short-term money market instruments at nominal rates of interest. 2004 Compared to 2003 Consolidated net interest income (expense) was income of $120 in 2004 compared to expense of $80 in 2003. This change in expense was primarily due to the repayment of its term loan in the third quarter of 2003, the interest earned on the installment note it received as a result of its sale of the VACMAN Enterprise business in 2003 and an increase in average net cash balances resulting from its strong operating cash flow throughout 2004. Average net cash balances were $6,500 in 2004, an increase of $4,450 or 217% from $2,050 in 2003. Our term debt of $3,400 and accrued interest was repaid in full in the third quarter of 2003. The term debt had an annual interest rate of 6%. OTHER INCOME (EXPENSE) 2005 Compared to 2004 Other income (expense) in 2005 primarily included exchange gains (losses) on transactions that are denominated in currencies other than the subsidiaries' functional currency and subsidies received from foreign governments related to increasing trade in other countries. The increase in other income (expense) of $1,045 in 2005 over 2004 primarily reflects changes in exchange gains and losses. We reported exchange gains of $330 in 2005 compared to exchange losses of $538 in 2004. We implemented a hedging program in the second quarter of 2005 to minimize the impact of changes in currency rates. 2004 Compared to 2003 30

Other income (expense) in 2004 primarily included exchange gains (losses) on transactions that are denominated in currencies other than the subsidiaries' functional currency. The increase in other expense of $654 in 2004 over 2003 primarily reflects an increase in exchange losses of $684 during that period. The exchange losses resulted from the increasing net U.S. Dollar asset base in Europe in combination with the strengthening Euro. Exchange losses reflected in other income were more than offset by translation surpluses recorded in the cumulative translation adjustment account in the shareholders' equity section of the consolidated balance sheet. INCOME TAXES 2005 Compared to 2004 Income tax expense for 2005 was $3,827 and compares to expense of $1,880 in 2004. The expense related primarily to our subsidiaries in Belgium, the Netherlands and Singapore, whose tax loss carryforward was fully utilized in 2005. The effective tax rate in 2005 was 33.2%, a decrease of 3.4 percentage points from 36.6% in 2004. The tax loss carryforward in Singapore utilized in 2005 reduced 2005 tax expense by approximately $180. The tax rate also reflected an improvement in earnings in countries in which we continue to have a tax loss carryforward. 2004 Compared to 2003 Income tax expense for 2004 was $1,880 and compares to expense of $397 in 2003. The expense related primarily to the Belgian operating subsidiary, whose tax loss carryforwards were fully utilized in 2003. The effective tax rate in 2004 was 36.6%, an increase of 2.3 percentage points from 34.3% in 2003. The Belgian tax loss carryforward utilized in 2003 reduced 2003 tax expense by approximately $739. Loss Carryforwards Available At December 31, 2005, the Company has U. S. net operating loss carryforwards of $25,810 and foreign net operating loss carryforwards of $4,595. Such losses are available to offset future taxable income in the respective jurisdictions. The U. S. loss carryforwards expire in varying amounts beginning in 2012 and continuing through 2018. The foreign loss carryforwards have no expiration dates. In addition, if certain substantial changes in the Company's ownership are deemed to have occurred, there would be an annual limitation on the amount of the U.S. carryforwards that could be utilized. LIQUIDITY AND CAPITAL RESOURCES At December 31, 2005, the Company had net cash balances (total cash, cash equivalents and restricted cash less bank borrowings), totaling $13,970 and no outstanding term debt. Cash generated from operating activities was $7,542 during the year ended December 31, 2005. During 2005, we used $4,456 for investing activities, primarily related to the acquisition of AOS-Hagenuk, and generated $6,614 in financing activities, primarily consisting of an increase in bank borrowing and proceeds from the exercise of stock options. Capital expenditures were $507 for the year ended December 31, 2005. Cash generated from operating activities was $2,877 during the year ended December 31, 2004. During 2004, we used $94 in investing activities and generated $54 in financing activities consisting of a proceeds from the exercise of stock options and warrants partially offset by dividends paid on our preferred stock. Capital expenditures were $252 for the year ended December 31, 2004. In July 2000, the Company issued 150,000 shares of Series C Convertible Preferred Stock (the "Series C Preferred Stock") and warrants to purchase 1,269,474 shares of Common Stock for cash of $15,000 to Ubizen N.V. ("Ubizen"). The preferred stock was convertible into 1,052,632 shares of Common Stock at any time through July 2003. If not converted by July 2003, the preferred stock would have been, at the option of the Company, either repurchased or converted into Common Stock at a rate equal to the average market price of the Common Stock for 30 consecutive business days on which the common stock was traded prior to the conversion date less five (5) percent. In July 2003, the Company reached an agreement with Ubizen whereby it purchased and redeemed all of the Series C Convertible Preferred Stock and Common Stock Purchase Warrants owned by Ubizen in exchange for 31

$4,000 in cash and 2,000,000 shares of Common Stock. Under the terms of the Purchase Agreement, the Company paid $3,000 to Ubizen and issued 2,000,000 shares of Common Stock on July 25, 2003. An additional $1,000 was paid to Ubizen in November 2003. Using the closing price of the Common Stock on July 25, 2003, the value of the stock issued was $4,000. The Common Stock issued by the Company was subject to a lock-up period wherein the lock-up expired in increments of 500,000 shares each on October 15, 2003, January 15, 2003, April 15, 2003 and July 15, 2003. Once the lock-up expired, the shares were subject to volume trading restrictions through January 1, 2005. On September 11, 2003, the Company sold 800 shares, with a stated valued of $10,000 per share, of its Series D 5% Cumulative Convertible Voting Preferred Stock (the "Series D Preferred Stock") and 600,000 warrants to purchase Common Stock. The Series D Preferred Stock carried a 5% dividend and was convertible into 4,000,000 shares of Common Stock at a fixed price of $2.00 per share. The net proceeds from the sale totaled $7,260 of which $5,786 was allocated to the Series D Preferred Stock and $1,474 was allocated to the warrants based upon their relative fair values. In addition, a beneficial conversion value was calculated for the Series D Preferred Stock as the difference between the price of the Common Stock at the transaction date and the conversion price of the Series D Preferred Stock. The amount of the beneficial conversion, $3,720, is analogous to a dividend and was recorded to accumulated deficit. On February 4, 2005, the Company acquired all of the share capital of A.O.S. Hagenuk B.V. ("AOS") a private limited liability company organized and existing under the laws of the Netherlands. The base purchase price was EUR 5,000 of which EUR 3,750 was paid in cash and the remainder was paid in the Company's common stock. The common stock was held in escrow for the benefit of the seller for a period of twelve (12) months. In addition to the base purchase price, a variable amount related to the gross profits collected on the sales of certain equipment will be paid to the seller over a period of two (2) years following the closing. AOS is a wholly owned subsidiary of the Company. On February 17, 2005, the Company, in accordance with the Designation of Rights and Preferences of the Series D 5% Cumulative Convertible Voting Preferred Stock (the "Series D Preferred Stock"), issued a call for the mandatory conversion of all outstanding shares of the Series D Preferred Stock. All accrued dividends through the conversion date have been paid. The Company maintains an overdraft agreement with Fortis Banque/Bank of Belgium. Under terms of the agreement, the Company can borrow an amount equal to 80% of its Belgium subsidiary's defined accounts receivable up to a maximum of either 3,500 Euros or U.S. dollars. Borrowings under the overdraft agreement accrue interest at an annual rate of 5.7% and the Company is obligated to pay a quarterly commitment fee of 0.125%. As of December 31, 2005, 327 Euros or U.S. dollars were available under the overdraft agreement as there were borrowings or $3,173 outstanding under the agreement as part of our currency hedging program. The assets, excluding inventory, of the Belgian subsidiary secure the agreement and while it has no specific termination date, it can be terminated with thirty (30) days notice. The agreement is governed by the General Lending Conditions for Corporate Customers, registered in Brussels, Belgium on December 20, 2001. The net effect of 2005 activity resulted in an increase in net cash of $5,750 and a net cash balance of $13,970 at December 31, 2005, compared to $8,220 at the end of 2004. Our working capital at December 31, 2005 was $16,325, an increase of $6,330 from $9,995 at December 31, 2004. The change is primarily attributable to the generation of positive cash flow from operations in 2005. Our current ratio was 2.03 to 1.0 at December 31, 2005. We believe that our current cash balances, credit available under our existing overdraft agreement and the anticipated cash generated from operations, including the realization of deferred revenue recorded as a current liability and deposits received on orders of Digipass to be delivered in 2006, will be sufficient to meet our anticipated cash needs for the next twelve months. The net effect of 2004 activity resulted in an increase in cash of $3,403 and a total cash balance of $8,220 at December 31, 2004, compared to $4,817, at the end of 2003. Our working capital at December 31, 2004 was $9,995, an increase of $4,777 from $5,218 at December 31, 2003. The change is primarily attributable to the generation of positive cash flow from operations in 2004. Our current ratio was 2.41 to 1.0 at December 31, 2004. We believe that our financial resources and current borrowing arrangements are adequate to meet our operating needs. There is risk, however, that our revenue and cash receipts will not be sufficient to meet the 32

operating needs of the business. If this is the case, we will need to 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 revenues and cash receipts. It is also likely that we would incur substantial non-recurring costs to implement one or more of these restructuring actions. OFF-BALANCE SHEET ARRANGEMENTS The Company has no off-balance sheet arrangements. CONTRACTUAL OBLIGATIONS The Company has the following contractual obligations: Payments Due by Period ------------------------------------------------ Less than 1-3 3-5 More than Total 1 year years years 5 years ------ --------- ------ ------ --------- Operating lease obligations $4,580 $1,048 $1,825 $1,302 $405 Purchase obligations 1,160 1,160 -- -- -- Deferred warranty 338 83 250 5 -- ------ ------ ------ ------ ---- Total contractual obligations $6,078 $2,291 $2,075 $1,307 $405 ====== ====== ====== ====== ==== "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 revenues 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, investments in SecureD Services, Inc. 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 AICPA Statement of Position ("SOP") 97-2 and SEC Staff Accounting Bulletin ("SAB") 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: Revenues from the sale of computer security hardware or the license of software are 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. Support Agreements: Support agreements generally call for us to provide technical support and software updates to customers. Revenue on technical support and software update rights is deferred and recognized ratably over the term of the 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. 33

Multiple-Element Arrangements: We allocate revenues to the various elements of the arrangements based on the estimated fair value of each deliverable as required by SOP 97-2 and Emerging Issues Task Force ("EITF") Issue No. 00-21. The fair value for each element is based on the price charged when that element is sold separately, price lists, renewal rates and other methods. When discounts are given in a multiple-element arrangement, a proportionate amount of the discount is applied to each element based on each element's fair value without regard to the discount. The estimated fair value of undelivered elements is deferred and recorded as revenue when services are performed or products are delivered. Sales to distributors and resellers are recognized on the same basis as sales made directly to customers. 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. 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 maintain reserves for 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 writedowns may be required. Valuation of Investment in Secured Services, Inc.: The initial value of consideration received from SecureD Services, Inc. ("SSI"), in exchange for the assets of the VACMAN Enterprise business unit, was established based on a detailed valuation analysis. On an ongoing basis, we review information made available by SSI through its filings with the SEC and its press releases and consider it within the context of the assumptions made in the valuation analysis. We also monitor SSI's compliance with the terms of the specific investment instruments to which they relate. Considering the start-up nature of SSI, the highly-competitive environment in which they operate and the uncertainty associated with SSI's access to additional capital, it may be that SSI's business prospects will deteriorate and, as a result, require us to reduce the value of our investment in SSI. The investment in SSI as of December 31, 2005 was $820, consisting of $220 remaining on the note receivable and $600 for the preferred shares, common shares and dividend receivable. SSI has made its note payment in January 2006, but has not made its note payments in February or March 2006. We have granted SSI a 90-day extension on the note in order to facilitate their planned capital raise. On February 28, 2006, SSI filed a Form 8-K report announcing a new financing arrangement, initially for $2,500, with a potential additional $2,500. If SSI is unsuccessful in executing their business plan, the remaining amount of our investment is at risk. We hold a security interest in the software sold to SSI under the terms of the installment note. Valuation of Goodwill and Other Intangible Assets and Software Development Costs: We assess the impairment of intangible assets and goodwill annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important which could 34

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. We assess the recoverability of its purchased software against estimated future revenue for the individual products over the estimated remaining economic life of the software. When we determine that the carrying value of intangibles and goodwill may not be recoverable based upon the existence of one or more of the above indicators of impairment, we measure any impairment based on a projected discounted cash flow method using a discount rate determined by our management to be commensurate with the risk inherent in our current business model. Given the highly competitive environment and frequency of technological changes in our industry, it is reasonably possible that estimates of anticipated future revenue, the remaining economic life of our software products, or both may be reduced significantly. The total amount of goodwill and other intangible assets as of December 31, 2005 was $7,719 and the full amount is at risk of impairment. See footnotes 1 and 2 to the consolidated financial statements for more detailed information. Research and Development: We are devoting substantial capital and other resources to enhance our existing security products and develop new products to provide identity authentication security solutions on different platforms and for different applications. Costs of research and development, principally the design and development of hardware and software prior to the determination of technological feasibility, are expensed as incurred on a project-by-project basis. Our software capitalization policy currently defines technological feasibility as a functioning beta test prototype with confirmed manufacturability (a working model), within a reasonably predictable range of costs. Additional criteria include receptive customers, or potential customers, as evidenced by interest expressed in a beta test prototype, at some suggested selling price. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In November 2004, the FASB issued SFAS No. 151, Inventory Costs: an amendment of ARB No. 43, Chapter 4. SFAS No. 151 amends guidance in ARB No. 43, Chapter 4, clarifying the accounting for abnormal amounts of idle facility expense, freight, handling costs and wasted material. These items are to be recognized as current-period charges. We have no idle facility expense or wasted material charges. This statement is effective for our 2006 fiscal year. SFAS No. 151 will not have a significant impact on our results of operations or financial position. In December 2004, the FASB issued SFAS No. 153, Exchange of Nonmonetary Assets. This is an amendment of APB Opinion No. 29 and eliminates the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. A nonmonetary exchange has commercial substance if the future cash flows are expected to change significantly as a result of the exchange. This statement is effective for our 2006 fiscal year. Adoption of this statement is not expected to have a material impact on our results of operations or financial position. In December 2004, the FASB issued SFAS No. 123R, Share-Based Payment, ("SFAS 123R"). This statement is a revision of SFAS 123 and supersedes APB Opinion no. 25, Accounting for Stock Issued to Employees. SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair value. The SEC issued guidance on April 14, 2005 announcing that public companies will now be required to adopt SFAS 123R by their first fiscal year beginning after June 15, 2005. Accordingly, we will adopt SFAS 123R in our first quarter of fiscal year 2006. We are currently evaluating the provisions of this statement to determine the impact on our consolidated financial statements. It is, however, expected to have a negative effect on consolidated net income, comparable to the pro forma amounts for prior years shown in footnote 1. ITEM 7A - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. (IN THOUSANDS) 35

Foreign Currency Exchange Risk - In 2005, approximately 93% of our business was conducted outside the United States, primarily in Europe 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 a foreign subsidiary 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 foreign subsidiaries' business transactions are spread across numerous countries and currencies. This geographic diversity reduces the risk to our operating results. Interest Rate Risk - We have minimal interest rate risk. Our outstanding debt at December 31, 2005 was $3,173 and was at fixed interest rates and 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 $170 annually. Impairment Risk - At December 31, 2005, we had goodwill of $6,665 and other intangible assets of $1,054 related mostly to the acquisition of AOS in 2005 and to technology purchased in 2001 as part of our acquisition of Identikey. We will assess the net realizable value of the goodwill and other intangible assets on a regular basis, but at least annually, to determine if we have incurred any declines in the value of our capital investment. While we did not experience impairment during the year ended December 31, 2005, 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-22 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 The Company maintains a system of disclosure controls and procedures that is designed to ensure that information required to be disclosed by the Company in this Annual Report on Form 10-K, and in other reports required to be filed under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission for such filings. As required by Rule 13a-15(b) under the Exchange Act, management of the Company, under the direction of the Company's Chief Executive Officer and Chief Financial Officer, reviewed and performed an evaluation of the effectiveness of the Company's disclosure controls and procedures. Based on that review and evaluation, the Chief Executive Officer and Chief Financial Officer, along with the management of the Company, have determined that the disclosure controls and procedures were and are effective as designed to ensure that information relating to the Company and its consolidated subsidiaries would be accumulated and communicated to them, as appropriate, to allow timely disclosures regarding required disclosures. CHANGES IN INTERNAL CONTROLS There were no significant changes in the Company's internal controls during the year ended December 31, 2005. 36

MANAGEMENT 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 Securities Exchange Act of 1934 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. A control system, no matter how well designed and implemented, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Further, 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. Our management assessed the effectiveness of its internal control over financial reporting as of December 31, 2005. 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, 2005, 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 our assessment of our internal control over financial reporting. Their report on management's assessment and their opinion on the effectiveness of the Company's internal control over financial reporting appear below. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders VASCO Data Security International, Inc.: We have audited management's assessment, presented in Management's Annual Report on Internal Control over Financial Reporting, that VASCO Data Security International, Inc. maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control--Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). 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. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of the Company's internal control over financial reporting based on our audit. 37

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, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and 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, management's assessment that VASCO Data Security International, Inc. maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, VASCO Data Security International, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on the COSO criteria. 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, 2005 and 2004, 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, 2005, and our report dated March 15, 2006 expressed an unqualified opinion on those consolidated financial statements.

ITEM 13 - CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS In July 2003, the Company sold its VACMAN Enterprise business unit ("VACMAN") to SecureD Services, Inc. ("SSI"), a then newly organized company in which T. Kendall Hunt had a 19% equity ownership interest and is one of seven directors currently on its board. The transaction was approved by all of the independent directors of the Company. The Company received a $1.1 million senior secured promissory note and 2,000,000 shares of convertible preferred stock from SSI in exchange for the VACMAN assets. The note is payable in 36 monthly installments and bears interest at 6% per annum. The preferred stock pays a 6% cumulative stock dividend quarterly, and may be converted into SSI common stock on a share-for-share basis in phases commencing July 1, 2005. We valued the transaction at approximately $1.6 million, using a discounted value of the payment streams expected from the note and preferred stock. SSI has since merged with a public company and its common stock is traded on the OTC Bulletin Board. SSI has made all of its note payments through January 2006, but has not made its note payments in February or March 2006. We have granted SSI a 90-day extension on the note in order to facilitate their planned capital raise. On February 28, 2006, SSI filed a Form 8-K report announcing a new financing arrangement for an 45

initial $2.5 million, with a potential additional $2.5 million. If SSI is unsuccessful in executing their business plan, the remaining amount of our investment is at risk. We hold a security interest in the software sold to SSI under the terms of the installment note. As of February 28, 2006, Mr. Hunt had a beneficial ownership share of 8% in SSI. VASCO does not use the equity method to account for its investment in SSI because we believe that he does not have "significant influence" over the operating and finance policies of SSI. Accounting Principles Board Opinion 18 established 20% ownership as a benchmark indicator of significant influence. Emerging Issues Task Force (EITF) Issue 02-14 "Whether an Investor Should Apply the Equity Method of Accounting to Investments Other Than Common Stock" describes situations where side agreements or ownership of instruments other than common stock can indicate the existence of significant influence. No such side agreements exist and VASCO's investment in convertible preferred shares does not create significant influence. ITEM 14 - PRINCIPAL ACCOUNTANT FEES AND SERVICES The following sets forth the amount of fees paid to our registered public accounting firm, KPMG LLP, for services rendered in 2005 and 2004 (in thousands): AUDIT FEES: The aggregate fees billed by KPMG LLP for professional services rendered for the audit of the Company's annual financial statements, the reviews of the financial statements included in the Company's quarterly reports on Form 10-Q, and services normally provided by the independent auditor in connection with statutory and regulatory filings were $367 for fiscal year ended 2005, and $251 for the fiscal year ended December 31, 2004. AUDIT-RELATED FEES: There were no audit-related fees paid in 2005 or 2004. TAX FEES: The aggregate fees billed by KPMG LLP for tax compliance and tax advice were $2 in 2005 and $39 in 2004. The fees for 2005 and 2004 primarily related to the filing of the Company's tax returns. ALL OTHER FEES: Fees for due diligence and reviews of registrations related to the acquisition of AOS Hagenuk aggregated $55 in 2005. There were no such fees in 2004. It is currently the policy of the Audit Committee of the Board of Directors to pre-approve all services rendered by KPMG LLP. The Audit Committee pre-approved all of the above fees for both 2005 and 2004.

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 as of December 31, 2005 and 2004, 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, 2005. In connection with our audits of the consolidated financial statements, we have also audited the accompanying consolidated financial statement Schedule II - Valuation and Qualifying Accounts. These consolidated financial statements and the consolidated financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements and the consolidated financial statement schedule based on our audits. We conducted our audits in accordance with 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 VASCO Data Security International, Inc. and subsidiaries as of December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2005, 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 effectiveness of VASCO Data Security International, Inc.'s internal control over financial reporting as of December 31, 2005, 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 15, 2006 expressed an unqualified opinion on management's assessment of, and the effective operation of, internal control over financial reporting.

VASCO DATA SECURITY INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA) NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations VASCO Data Security International, Inc. and its wholly owned subsidiaries (the Company) 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 Belgium, Australia, Singapore, Shanghai and the United States (U.S.). Principles of Consolidation The consolidated financial statements include the accounts of VASCO Data Security International, Inc. and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Foreign Currency Translation and Transactions The financial position and results of operations of the Company's foreign subsidiaries are measured using the local currency as the functional currency. Accordingly, assets and liabilities are translated into U.S. dollars using current exchange rates as of the balance sheet date. Revenues and expenses are translated at average exchange rates prevailing during the year. Translation adjustments arising from differences in exchange rates are included as a separate component of stockholders' equity. Gains and losses resulting from foreign currency transactions are included in the consolidated statements of operations. Foreign exchange transaction gains (losses) aggregating $330, $(538) and $146 are included in other income (expense) for 2005, 2004 and 2003, respectively. We implemented a hedging program in the second quarter of 2005 to minimize the impact of changes in currency rates. Revenue Recognition The Company recognizes revenue in accordance with AICPA Statement of Position ("SOP") 97-2 and SEC Staff Accounting Bulletin ("SAB") 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: Revenues from the sale of computer security hardware or the license of software are 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. Support Agreements: Support agreements generally call for the Company to provide technical support and software updates to customers. Revenue on technical support and software update rights is deferred and recognized ratably over the term of the support agreement. Consulting and Education Services: The Company provides consulting and education services to its customers. Revenue from such services is recognized during the period in which the services are performed. Multiple-Element Arrangements: The Company allocates revenues to the various elements of the arrangements based on the estimated fair value of each deliverable as required by SOP 97-2 and Emerging Issues Task Force ("EITF") Issue No. 00-21. The fair value for each element is based on the price charged when that element is sold separately, price lists, renewal rates and other methods. When discounts are given in a multiple-element arrangement, a proportionate amount of the discount is applied to each element based on each element's fair value without regard to the discount. The estimated fair value of undelivered elements is deferred and recorded as revenue when services are performed or products are delivered. Sales to distributors and resellers are recognized on the same basis as sales made directly to customers. 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. F-8

VASCO DATA SECURITY INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED) (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA) For large-volume transactions, the Company 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. Cash and equivalents The Company classifies as cash and equivalents amounts on deposit in banks and cash invested temporarily in various instruments with maturities of three months or less at time of purchase. Restricted cash of $181 at December 31, 2005 supports a bank guarantee issued in favor of a customer relating to a contract prepayment. Under the terms of the contract, the Company will have unrestricted use of this cash when it has fulfilled its commitment to deliver the products. The customer has the right to put a claim on the guarantee if the Company does not perform. The guarantee automatically ceases on January 31, 2012, but can be cancelled earlier upon mutual agreement of both parties or when all of the products have been delivered. The Company has materially fulfilled the contract during 2005 and it is the Company's intention to fulfill remaining deliveries during the first quarter of 2006. Accounts Receivable and Allowance for Doubtful Accounts The Company records trade accounts receivable at invoice values, which are generally equal to fair value. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make payments for goods and services. The Company analyzes 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. 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. The Company maintains reserves for inventory where it appears that the carrying cost of the inventory may not be recovered through subsequent sale of the inventory. The Company analyzes 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 writedowns 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 software prior to the determination of technological feasibility, are expensed as incurred on a project-by-project basis. The Company's research and development costs were $3,579, $2,441 and $1,955 for 2005, 2004 and 2003, respectively. Software Development Costs The Company capitalizes software development costs in accordance with Statement of Financial Accounting Standards (SFAS) No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed". F-9

VASCO DATA SECURITY INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED) (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA) 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. The Company's policy is to amortize capitalized costs by the greater of (a) the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product or (b) the straight-line method over the remaining estimated economic life of the product, generally two to five years, including the period being reported on. The Company did not capitalize any software costs during the years ended December 31, 2005, 2004 and 2003. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company has 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 these future benefits because we have not determined that their realization is more likely than not. Fair Value of Financial Instruments At December 31, 2005 and 2004 the Company's financial instruments were accounts receivable, notes receivable, accounts payable and accrued liabilities. The estimated fair value of the Company's financial instruments has been determined by using available market information and appropriate valuation methodologies. The fair values of the Company's financial instruments were not materially different from their carrying amounts at December 31, 2005 and 2004. Use of Estimates 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 revenues and expenses during the reporting period. Actual results could differ from those estimates. Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed of The Company accounts for long-lived assets in accordance with the provisions of SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." The statement requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company assesses the recoverability of long-lived assets and certain intangibles by comparing the carrying amount of the asset to a projected discounted cash flow expected to result and eventual disposition of the asset. If an asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying value of the asset exceeds the fair value of the asset. Valuation of Investment in Secured Services, Inc. The Company received from Secured Services, Inc. ("SSI") preferred stock and a note receivable in 2003 as consideration for assets of the VACMAN Enterprise business unit. Based on a detailed valuation, we established the initial value of the consideration received from SSI, using a discounted value of the payment streams expected from the note and the preferred stock. Interest income on the note is recorded over time at the discount rate. On an ongoing basis, the Company F-10

VASCO DATA SECURITY INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED) (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA) reviews information made available by SSI through its public filings and evaluates that information within the context of the assumptions made by the independent valuation firm to determine if a reduction in the value of the investment in SSI is required. As of February 28, 2006, the Company's Chief Executive Officer, T. Kendall Hunt, had a beneficial ownership share of 8% in SSI. The Company does not use the equity method to account for its investment in SSI because we believe that Mr. Hunt does not have "significant influence" over the operating and finance policies of SSI. Accounting Principles Board Opinion 18 established 20% ownership as a benchmark indicator of significant influence. Emerging Issues Task Force (EITF) Issue 02-14 "Whether an Investor Should Apply the Equity Method of Accounting to Investments Other Than Common Stock" describes situations where side agreements or ownership of instruments other than common stock can indicate the existence of significant influence. No such side agreements exist and the Company's investments in convertible preferred shares and the note do not create significant influence. SSI has made all of its note payments through January 2006, but has not made its note payments in February or March 2006. The Company granted SSI a 90-day extension on the note in order to facilitate their planned capital raise. On February 28, 2006, SSI filed a Form 8-K report announcing a new financing arrangement for an initial $2,500 and a potential additional $2,500. If SSI is unsuccessful in executing their business plan, the remaining amount of the Company's investment is at risk. The Company holds a security interest in the software sold to SSI under the terms of the installment note. EITF Issue No. 03-1 "The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments" provides guidelines for valuation of these investments. Based on a review of the facts, the Company has concluded that the current decline in fair value, if any, is temporary in nature. The Company has the ability and intent to hold the investment until its carrying value is realized. At December 31, 2005, there was no reduction in the carrying value of the Company's investment in SSI. Goodwill and Other Intangibles The Company accounts for goodwill and other intangible assets in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets". This statement replaced the requirements to amortize intangible assets with indefinite lives and goodwill with a requirement for an impairment test. SFAS 142 also established requirements for identifiable intangible assets, which included customer lists, proprietary technology. 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. The Company assesses the impairment of intangible assets and goodwill each year-end or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company completed its last review during December 2005. 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. The Company assesses the recoverability of its software development costs against estimated future revenue for the individual products over the estimated remaining economic life of the software. When the Company determines that the carrying value of intangibles and goodwill may not be recoverable based upon the existence of one or more of the above indicators of impairment, any impairment is measured based on a projected discounted cash flow method using a discount rate determined by management to be commensurate with the risk inherent in the current business model. Given the highly competitive environment and technological changes, it is reasonably possible that estimates of anticipated future revenue, the remaining economic life of the Company's software products, or both may be reduced significantly. Stock-Based Compensation At December 31, 2005, the Company had a stock-based employee compensation plan, which is described more fully in Note 9. The Company accounts for the plan under the recognition and measurement principles of APB Opinion No. 25, "Accounting for Stock Issued to Employees", and related Interpretations. No stock-based employee compensation cost for options is reflected in net income, as all options granted under this plan had an exercise price equal to the market value of the underlying Common Stock on the date of grant. In 2005, the Company granted restricted stock awards for 90,000 common shares, which will vest over a four year period.

The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of FASB Statement No. 123, "Accounting for Stock-Based Compensation", to stock-based employee compensation: Year Ended December 31, -------------------------- 2005 2004 2003 ------ ------- ------- Net income (loss) available to common shareholders as reported $7,687 $ 3,021 $(1,715) Incremental stock-based employee compensation determined under fair-value-based methods for options, net of tax (726) (1,065) (1,016) ------ ------- ------- Pro forma net income (loss) $6,961 $ 1,956 $(2,731) ====== ======= ======= Non-cash compensation cost included in net income (loss) for restricted stock or option awards (no tax effect, due to NOL) $ 135 $ -- $ 41 ====== ======= ======= Basic net income (loss) per common share As reported $ 0.22 $ 0.09 $ (0.06) Pro forma $ 0.20 $ 0.06 $ (0.09) Diluted net income (loss) per common share As reported $ 0.21 $ 0.09 $ (0.06) Pro forma $ 0.19 $ 0.06 $ (0.09) For purposes of calculating the compensation cost consistent with SFAS No. 123, the fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants in 2005, 2004 and 2003: dividend yield of 0%; expected volatility of 69%, 104%, 120%, respectively; risk free interest rates ranging from 4.21% to 4.23%, 4.08% to 4.27% and 4.07% to 4.19%, respectively; and expected lives ranging from 4 to 7 years. The pro forma compensation cost for options is reduced for expected prevesting forfeitures and is amortized on a straight-line basis over the vesting period. Pro forma compensation cost is adjusted for actual forfeitures when they differ significantly from expected forfeitures. Effective January 1, 2006, the Company will adopt SFAS 123(R), "Share-Based Payment". This statement will require that fair value of options granted be included in expense over the vesting period. It is expected that the expense amounts recorded will be comparable to the estimated pro forma amounts reported under SFAS 123 in the table above. Deferred Warranty The Company's standard practice is to provide a warranty on its authenticators for one year after the date of purchase. Customers may purchase extended warranties covering periods from one to three years after the standard warranty period. The Company defers the revenue associated with the extended warranty and recognizes it into income on a straight-line basis over the extended warranty period. The Company has historically experienced minimal actual claims over the warranty period. Earnings per Common Share Basic earnings per share are based on the weighted average number of shares outstanding and exclude 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: F-12

Reclassifications Certain prior year amounts in the consolidated financial statements have been reclassified to conform to the 2005 presentation, primarily to reflect amortization expense on the income statement as a separate line item and to reclassify certain payroll-related items from other accrued liabilities to accrued payroll on the balance sheet.

("AOS") a private limited liability company organized and existing under the laws of the Netherlands. The primary purpose for the acquisition was to obtain engineering expertise which is complimentary to our existing product lines. The base purchase price was EUR 5,000, of which EUR 3,750 was paid in cash and the remainder was paid in the Company's Common Stock. In addition to the base purchase price, a variable amount related to the gross profits collected on the sales of certain equipment will be paid to the seller over a period of two (2) years following the closing. AOS will be operated as a wholly-owned subsidiary of the Company, accounted for using the purchase method in accordance with SFAS No. 141, Business Combinations. The aggregate purchase price was $7,263, consisting of $4,374 of cash, 262,641 shares of Common Stock valued at approximately $2,128, the assumed liability due AOS of $616 and direct costs of the acquisition of $145. The fair value of the common stock was determined based on the average market price of the Company's Common Stock over the period including several days before the closing date, February 4, 2005.

Such losses are available to offset future taxable income in the respective jurisdictions. The U. S. loss carryforwards expire in varying amounts beginning in 2012 and continuing through 2018. The foreign loss carryforwards have no expiration dates. 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 assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which these temporary differences become deductible. This valuation allowance will be reviewed on a regular basis and adjustments made as appropriate. In 2005 and 2004, the Company utilized $560 and $1,060 of its U. S. net operating loss carryforwards. In 2005, the Company also utilized $1,235 of foreign net operating loss carryforwards and generated $936 of new foreign net operating loss carryforwards. The Company has provided a valuation allowance at December 31, 2005 for all of the gross deferred tax assets except for those associated with its Belgian operating entity. The Company anticipates realizing this deferred tax asset in the future as the Company expects to generate taxable income in Belgium in 2006. NOTE 6 - DEFERRED WARRANTY The Company's standard practice is to provide a warranty on its Digipasses for two years after the date of purchase. Customers may purchase extended warranties covering periods from one to four years after the standard warranty period. The Company defers the revenue associated with the extended warranty and recognizes it into income on a straight-line basis over the extended warranty period. Deferred warranty at December 31, 2005 which will be earned in 2006 is $83 and is included in other current assets. The long-term deferred warranty revenue as of December 31, 2005 will be recognized as income as follows: F-17

Under terms of the agreement, the Company can borrow an amount equal to 80% of its Belgium subsidiary's defined accounts receivable up to a maximum of 3,500 U.S. Dollars or Euros. Borrowings under the overdraft agreement accrue interest at an annual rate of 5.7% and the Company is obligated to pay a quarterly commitment fee of 0.125%. As of December 31, 2005, borrowings under the agreement totaled $3,173. The assets, excluding inventory, of the Belgian subsidiary secure the agreement and while it has no specific termination date, it can be terminated with thirty (30) days notice. The agreement is governed by the General Lending Conditions for Corporate Customers, registered in Brussels, Belgium on December 20, 2001. In August 1997, the Company renegotiated the guarantee with Artesia Bank N.V., formerly Banque Paribas Belgique S.A. and is now doing business as Dexia Bank ("Dexia") related to the final payment for the 1996 acquisition of Digipass into a term loan in the amount of $3,400 with a maturity date of September 30, 2002 and an interest rate of 3.25%. In August 2001, the Company agreed to revise the terms of the loan. Under the new terms, the loan was convertible into shares of VASCO Common Stock at the fixed conversion rate of $7.50 per share rather than a floating rate based on the market price of the VASCO Common Stock. Also, the maturity date of this convertible loan was reset to September 30, 2003 with a revised interest rate of 6%. On September 11, 2003, the Company sold $8,000 of its Series D Preferred Stock and Warrants to purchase Common Stock. A portion of the proceeds was used to repay the debt to Dexia including accrued interest. Interest expense related to debt was $120, $0 and $157 for the years ended December 31, 2005, 2004 and 2003, respectively. NOTE 8 - STOCKHOLDERS' EQUITY Preferred Stock On February 17, 2005, the Company, in accordance with the Designation of Rights and Preferences of the Series D 5% Cumulative Convertible Voting Preferred Stock (the "Series D Preferred Stock"), issued a call for mandatory conversion of all outstanding shares of the Series D Preferred Stock. The accrued dividends through the conversion date of $14 were paid. In addition, 5,075 shares of Common Stock were issued as dividends to the Series D preferred stockholders in the first quarter of 2005. On September 11, 2003, the Company sold 800 shares of Series D 5% Cumulative Convertible Voting Preferred Stock (the "Series D Preferred Stock") and 600,000 detachable warrants to purchase Common Stock. The Series D Preferred Stock carried a 5% dividend and was convertible into 4,000,000 shares of Common Stock at a fixed price of $2.00 per share. The implied value of the Series D Preferred Stock was $5,714 calculated based upon the annual dividend rate divided by a required rate of return. The warrants are exercisable, over a five-year period, at $3.47 per share and were valued at $1,455 using the Black-Scholes pricing model. Of the net proceeds from the sale, $5,786 was allocated to the Series D Preferred Stock and $1,474 was allocated to the warrants based upon their relative fair values. In addition, a beneficial conversion value was calculated for the Series D Preferred Stock as the difference between the price of the Company's Common Stock at the transaction date and the conversion price of the Series D Preferred Stock. The amount of the beneficial conversion, $3,720, is analogous to a preferred dividend and was recorded to accumulated deficit. In 2004, 592 shares of the Series D Preferred Stock were converted resulting in the issuance of 2,960,000 shares of the Company's Common Stock. See Common Stock. F-18

VASCO DATA SECURITY INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED) (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA) In July 2000, the Company issued 150,000 shares of Series C Preferred Stock for cash of $15,000. The preferred stock was convertible into 1,052,632 shares of Common Stock at any time through July 2004. In conjunction with this financing, the Company issued Common Stock Purchase Warrants to purchase 789,474 common shares at $15 per share with an estimated fair value, using the Black-Scholes pricing model, of approximately $4,100 and warrants to purchase 480,000 shares at $4.25 per share with an estimated fair value, using the Black-Scholes pricing model, of approximately $4,700. The warrants issued at $15 per share were immediately exercisable. The warrants issued at $4.25 were exercisable over 48 months and the related fair value was being accreted over their lives reducing earnings available to holders of Common Stock. The value of the warrants, which reduces the carrying value of the preferred stock, was being accreted and reduced earnings available to common shareholders. The preferred stock and warrants were purchased and redeemed by the Company on July 15, 2003. See Common Stock. Common Stock On July 15, 2003, the Company reached an agreement with Ubizen N.V. ("Ubizen") whereby VASCO purchased and redeemed all 150,000 shares of the Series C Convertible Preferred Stock (the "Series C Preferred Stock") and 1,239,474 Common Stock Purchase Warrants owned by Ubizen. Under the terms of the Purchase Agreement, the Company paid $4,000 to Ubizen and issued 2,000,000 shares of the Company's Common Stock on July 25, 2003 at a fair value of $4,000.

VASCO DATA SECURITY INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED) (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA) The Compensation Plan further permits the grant of options to directors, consultants and other key persons (non-employees) to purchase shares of Common Stock. All options granted to non-employees have been granted at a price equal to the fair market value of the Common Stock on the date of the grant, and have contained vesting requirements and/or restrictions as determined by the Compensation Committee at the time of grant. Non-cash compensation expense of $135, $0 and $41 was recognized in 2005, 2004 and 2003, respectively, in accordance with FASB Interpretation No. 44, "Accounting for Certain Transactions Involving Stock Compensation", an interpretation of Accounting Principles Board Opinion No. 25.

VASCO DATA SECURITY INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED) (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA) In 2002, the Company loaned Belgian employees who received stock options in 1999 and 2000, 142 Euros to pay taxes assessed on those options by the Belgian Government. Even though stock options granted to all employees were granted at prices equal to the fair market value of the Common Stock on the date of the grant, Belgian employees who were recipients of stock options were assessed taxes based on the value determined under Belgian tax legislation dated March 26, 1999. The total amounts advanced in 2002 were based on each recipient's specific tax assessment. Due to the uncertainty of collecting the amounts loaned to the employees, the notes have been fully reserved for as of December 31, 2005 and 2004. In 2005, the Company granted restricted stock awards for 90,000 common shares to employees. These awards vest over a four year period.

VASCO DATA SECURITY INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED) (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA) NOTE 11 - DISCONTINUED OPERATIONS In July 2003, VASCO sold its VACMAN Enterprise ("VME") business, originally known as Intellisoft and/or Snareworks, to SecureD Services, Inc. ("SSI"). Under the terms of the agreement, VASCO received a senior secured promissory note with a face value of approximately $1,100, valued at $1,000 for book purposes, and 2,000,000 shares of Convertible Preferred Stock from SSI, valued at $600 for book purposes, in exchange for the VACMAN Enterprise assets. The promissory note bears a 6% interest rate and is payable in 36 equal and consecutive monthly payments. The Preferred Stock includes a 6% cumulative stock dividend, payable quarterly, and can be converted into SSI's common stock at defined intervals beginning July 1, 2005. The valuation reserve taken on each asset received, that is the difference between the face value and the amount recorded for both the note and the preferred stock, reflects the Company's detailed assessment of the value of each of the financial instruments received. In its assessment, the Company considered, among other factors, the start-up nature of SSI, its business plan, its need for future financing, the trading activity of SSI's stock in the open market and a market rate of return for investments in start-up companies. In accordance with Statement of Financial Accounting Standard (SFAS) No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets", the assets and liabilities of this business unit have been disaggregated from the operational assets and liabilities of the Company. There were no assets of and liabilities related to discontinued operations as of December 31, 2005 and 2004. The results of the operations of VME for the twelve months ended December 31, 2003 have been reported as results of discontinued operations. The Company recorded a gain on the sale of $1,400, comprised of the proceeds of $1,600 less net basis in the assets sold and related fees of the sale. Prior to the sale, during 2003, discontinued operations had revenue of $1,033, cost of sales of $82 and operating expenses of $313. NOTE 12 - EMPLOYEE BENEFIT PLAN The Company maintains a defined contribution pension plan for its 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. In January 2001, the Company amended its benefit plan to allow Company-matching. For the years ended December 31, 2005, 2004 and 2003, the Company contributed $31, $21 and $23, respectively, to this plan. The Company also maintains a pension plan for its 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, 2005, 2004 and 2003, the Company contributed $160, $127 and $84, respectively, to this plan. F-22
