Selected Financial Data

The selected financial data for the fiscal years ended December 31, 2005, 2004, 2003 and October 31, 2003, 2002, and 2001, and for the fourteen months ended December 31, 2003 are derived from our audited financial statements. The selected financial data for the two months ended December 31, 2003 are derived from our unaudited financial statements. During 2003 we changed our fiscal year from October 31^st to December 31^st. The following selected financial data should be read in conjunction with the consolidated financialstatements and the notes thereto and “Operating Results” appearing in Item 5-A. of this annual report. As a result of a number of circumstances, including financing activities, the acquisition of DSS and Caradas and the U.S. dollar becoming the primary currency in which most of our business is transacted, effective October 1, 2003, we adopted the U.S. dollar as our measurement and reporting currency for preparation of our consolidated financial statements. In addition, except where otherwise indicated, all financial information in this report is presented in United States dollars.

Our financial statements have been prepared in accordance with Canadian GAAP. These principles conform in all material respects with U.S. GAAP except as described in Note 14 to our 2005 consolidated financial statements. Under U.S. GAAP share capital would be greater and deficit would be less by $30,089,000 for each of the years due to the elimination of reduction in stated capital offset against accumulated shareholders’ deficit in March of 1999 recorded under Canadian GAAP which would not have been recognized under US GAAP.

At our March 1999 Annual Meeting, our shareholders approved a resolution providing for the reduction of our stated capital by$30,089,000. This resulted in a reduction in our accumulated shareholders’ deficit in the same amount. At December 31, 2005, we had an accumulated deficit of$56,295,000. If our shareholders had not approved the reduction in our stated capital, our accumulated deficit at December 31, 2005 would have been $86,384,000 and December 31, 2004 would have been $79,274,000.

The following table sets forth the rate of exchange for the Canadian Dollar at the end of the five fiscal years ended December 31, 2005 and the end of each of the last six months, the average rates for the period, and the range of high and low rates for the period. For purposes of this table, the rate of exchange means the noon buying rate in New York City for cable transfers in foreign currencies as certified for customs purposes by the Federal Reserve Bank of New York. The table sets forth the number of Canadian Dollars required under that formula to buy one U.S. Dollar. The average rate means the average of the exchange rates on the last day of each month during the period.

3-D. Risk Factors

When used in this annual report, the words “may”, “will”, “expect”, “anticipate”, “continue”, “estimate”, “project”, “intend” “plan” and similar expressions are intended to identify forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, regarding events, conditions and financial trends that may affect Diversinet’s future plans of operations, business strategy, operating results and financial position. All statements, other than statements of historical facts, included or incorporated by reference in this document which address activities, events or developments which the Company expects or anticipates will or may occur in the future, including such things as future capital expenditures (including the amount and nature thereof), business strategy, expansion and growth of the Co mpany’s business and operations, and other such matters are forward-looking statements. These statements are based on certain assumptions and analyses made by the Company in light of its experience and its perception of historical trends, current conditions and expected future developments as well as other factors it believes are appropriate in the circumstances. Such statements are not guarantees of future performance and are subject to risks and significant uncertainties and that actual results may differ materially from those included within the forward-looking statements as a result of various factors. The occurrence of any unanticipated events may cause actual results to differ from those expressed or implied by the forward-looking statements contained herein. Prospective investors are cautioned that any forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties and that actual results may differ materially from those included wi thin the forward-looking statements as a result of various factors, some of which are described in the Risk Factors below.

We have limited financial resources, and if we fail to either raise capital when needed or generate revenues, we may need to cease operations. Our ability to continue operations during the next fiscal year may be dependent on our ability to obtain additional financing. Although we have made progress in developing our products and have completed initial consumer deployments, our revenue from operations is not sufficient to cover our operating expenses at present and is unlikely to be sufficient within fiscal 2006. We have obtained funding for operations from private equity placements in the past, but there is no assurance we will be able to do so again in the near future at commercially reasonable terms or at all despite the progress of the business. In September 2005 we completed a private placement with the issuance of 5,000,000 common shares at a price of $0.40 per common sh are and 71,250 common share purchase warrants for gross proceeds of $2,000,000 to us. The warrants expire on September 26, 2008 and are exercisable at $0.40 per share. In December 2004 we completed a private placement with the issuance of 6,625,000 common shares at a price of $0.40 per common share for gross proceeds of $2,650,000. In January 2004 we completed a private placement through the issuance of 1,000,000 common shares and 1,100,000 common share purchase warrants. We received gross proceeds of $2,000,000 in the transaction. The warrants were comprised of 500,000 warrants exercisable at $2.00 and 250,000 at $2.05 and 350,000 at $0.60. Each warrant entitles the holder thereof to acquire one common share for a period of three years. As well, the terms of new capital, if any, may materially dilute existing shareholders. Our failure to either raise capital when needed or to generate revenues would leave us with insufficient resources to continue our business .

We have lost money in the past, we have realized minimal revenues from continuing operations, we expect to continue to sustain losses in the future and may never achieve profitability. We have not generated sufficient revenue to date from the sales of our solutions and licensing of our products. For the year ended December 31, 2005, we posted a net loss of $7,109,000. For the year ended December 31, 2004, we posted a net loss of $7,517,000. For the year ended December 31, 2003, we posted a net loss of $4,959,000. For the fourteen months ended December 31, 2003, we posted a net loss of $5,618,000. For the year ended October 31, 2003, we posted a net loss of $4,834,000, and $4,065,000 for the year ended October 31, 2002. We generated revenue of $1,101,000 for the year ended December 31, 2005, $2,603,000 for the year ended December 31, 2004, $1,395,000 in the year ended December 31, 2003, $1,436,000 for the fourteen months ended December 31, 2003, $967,000 in the twelve months ended October 31, 2003, $710,000 in the year ended October 31, 2002. The auditors’ report on our December 31, 2005 consolidated financial statements included additional comments for U.S. readers that state that conditions and events exist that cast substantial doubt on our ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of that uncertainty. We may never achieve profitability or maintain profitability, if achieved, on a consistent basis.

Our business plan is dependent upon customer adoption and commercial deployment of our products; if our business plan is not accepted, we may need to cease operations. Our ability to continue operations is also dependent on the acceptance of our security solutions and the adoption of transaction-based applications using security and identity management over mobile data networks as an accepted method of data transmission in sufficient volume for us to generate enough revenues to fund our expenses and capital requirements. The mobile data market is in a very early stage, and it may not develop to a sufficient level to support our business.

We market our solutions to large companies and mobile network operators. The implementation of our solutions by these entities typically involves a lengthy education process and a significant technical evaluation and commitment of capital and other resources. This process is also subject to the risk of delays associated with customers’ internal budgeting and other procedures for approving large capital expenditures, deploying new technologies within their networks and testing and accepting new technologies that affect key operations. As a result, the associated sales and implementation cycles can be lengthy. Our quarterly and annual operating results could be materially harmed if orders forecasted for a specific customer for a particular quarter are not realized.

Many of our early licensing agreements permitted our customers to examine and test our products with no initial up-front payments to us. These customers are not required to make payments to us until they begin to use our solutions for commercial purposes. In certain cases, we also enter into evaluation agreements, whereby potential customers may examine our solutions for a specified period of time with no payment to us. Our current licensing agreements typically require the customer to pay a license fee attributable to the software components and the solution and upon shipment of these items to the customer, although we have sometimes waived the up-front fee.

We have a limited number of customers. The loss of, or a significant reduction in business from, any of these customers would materially harm our business and results of operations, and our future prospects depend substantially on expanding our customer base. During fiscal 2003, 49% of revenue was generated from one customer and 67% of revenue was generated from two customers. During fiscal 2004, 46% of revenue was generated from one customer and 64% of revenue was generated from two customers. During fiscal 2005, 38% of revenue was generated from one customer and 67% from two customers. The loss of revenues from one or more significant customers, or the failure to collect receivables due from a major customer in a timely manner would have a material adverse effect on our results of operations. If we are unable to expand our customer base, our results of operations wi ll suffer.

Fluctuations in foreign exchange may adversely affect our business. Our functional currency is the U.S. dollar. Sales generated outside Canada are generally denominated in U.S. dollars. During fiscal 2004 and 2005, we have incurred a large portion of our expenses in U.S. dollars, but we also incurred a smaller portion of our expenses in other currencies including Canadian dollars, Pound Sterling and Hong Kong dollars. Changes in the value of these currencies relative to the U.S. dollar may result in currency losses that may have an adverse effect on our operating results. With the completion of our financings in September 2005, we have a portion of our cash resources in U.S. dollar short-term investments and in Canadian dollars. During fiscal 2004 and fiscal 2005, we maintained a portion of our cash resources in both U.S. and Canadian dollar term deposits.

In February 2005, the Company’s subsidiary DSS Software Technologies (DSS) completed an agreement whereby it sold the majority of its current assets, capital assets, current liabilities, consultant and customer accounts for $250,000. Diversinet is entitled to a five-year annual fee of up to $120,000 per year based on the purchaser meeting certain gross profit and net profit criteria. These amounts will be recorded as income from discontinued operations, if and when received. An impairment analysis for DSS as at December 31, 2005 indicated that the fair value of goodwill was nil and accordingly we recorded an impairment charge of $392,242.

We may not be successful if we fail to attract and retain our key technical personnel. During 2004, in order to reduce our largest single expenditure, salaries and benefits, we reduced our headcount of employees in the Diversinet, DSS and Caradas operations. Workforce reductions may have a detrimental effect on the morale of remaining employees, impeding their performance levels. In addition, our ability to attract potential new employees in the future may suffer if our reputation was hurt by this staff reduction.

We currently have two senior officers and 27 employees and contractors. We may not be able to improve our solutions and products or create new products if we lose any of our key employees or contractors. We do not maintain key person life insurance policies on any of our employees. Skilled technical personnel can be difficult to attract depending on the strength of the economy and competitive opportunities. We may not be able to retain our current employees if they receive better job offers from other employers.

We are involved in litigation which could result in judgments against us which, in the aggregate, could total more than our combined current assets, working capital and net assets. There is currently one material claim pending against us. If we lose this suit or enter into settlement requiring us to pay cash or issue any of our common shares, our liquidity and financial position will be adversely affected, and our shareholders’ ownership may be diluted. In May 2000 we were sued, along with our wholly owned Barbados subsidiary, in an action in which the plaintiff is seeking damages of $1,533,950 for breach of an October 25, 1995 dealer agreement with our previous printing business regarding the distribution of printing equipment and damages of $25,000,000 for loss of reputation and loss of opportunity, pre-judgment and post-judgment interest, and costs.

We have limited experience in the mobile data security software and identity management solutions field, and we are therefore subject to risks inherent in establishing a new business. We have been in the mobile data security software field since fiscal 1997 and the identity management solutions field since 2001, and we have only generated minimal revenues from this business. We are not sufficiently established to fully evaluate or forecast our prospects, and we are subject to the risks inherent in establishing a new business enterprise.

Our ability to keep pace with the rapid technological changes and frequent new product introductions common in the information and communications technology industry will determine our ability to remain competitive and affect the viability of our products. To succeed in the mobile data security and the identity management solutions business, we believe that we will have to continuously improve the performance, features and reliability of our products and be the first to the market with new products or enhancements to existing products. We cannot provide assurance that we will be able to improve our products in a timely manner. The emerging market for security solutions for mobile data security and the identity management is characterized by rapid technological developments, frequent new product introductions and evolving industry standards. We anticipate this evolution will also occur in the mobile data security and the identity management solutions market in which we focus our technological developments. The adoption of new standards, or the informal adoption of certain standards by a significant percentage of the computer security and related industries, could require us to reconfigure our products. We may not be able to counter challenges to our current products or to introduce product offerings that keep pace with the technological changes introduced by competitors or persons seeking to breach information security. We are not currently aware of any significant new technologies either under development or about to be introduced in the mobile data security or the identity management solutions security field.

Further, our products are based on public key infrastructure based security (also known as PKI based security) and identity management technology and depend in part on the application of certain mathematical principles forming the basis of the encryption technology that we license and embed in our products. Any significant advance in techniques for decoding or cracking encrypted computer information could render our products obsolete or unmarketable.

Our products use algorithms, or mathematical formulae, to encrypt and secure information. The security afforded by our products is predicated on the assumption that these mathematical formulae are very difficult to solve. This assumption is based on the fact that years of theoretical and empirical research by leading mathematicians have not resulted in any efficient solutions to these problems. There can be no assurance, however, that future research will not uncover efficient solutions to these problems.

Also, even if no breakthrough in solving these problems is discovered, they may eventually be solved by computer systems having sufficient speed and power. If improved techniques for decoding encrypted information are developed or made possible by the increased availability of powerful computing resources, our products could be rendered obsolete.

The highly competitive nature of the information and communications technology fields could prevent us from achieving success. Our solutions are targeted at the new and rapidly evolving market for authentication and authorization products for mobile data communications, commerce, telecommunications and identity management. This market is not mature. We anticipate that it will be intensely competitive, subject to rapid change and significantly affected by new solution, product and service introductions and other market activities of industry participants. Many of our competitors and potential competitors have a longer operating history, greater name recognition, larger installed customer base and significantly greater financial, technical and marketing resources than we have. As a result, they may be able to adapt more quickly to new or emerging technologies and changes in customer requ irements, and they could therefore render our technologies and products obsolete.

Because of the broad potential application of our authentication and authorization software and identity management solutions, we compete with vendors offering a wide range of computer security products. These competitors include Entrust Technologies, Certicom and RSA Security. There also may be other potential entrants to the market of whom we are not yet aware.

Our licensing revenues are dependent on our customers’ acceptance and use of our software products, and we expect our sales cycle to be lengthy. Many of our early licensing agreements permitted our customers to examine and test our products with no initial up-front payments to us. These customers are not required to make payments to us until they begin to use our product for commercial purposes. We also enter into evaluation agreements in certain cases, whereby potential customers may examine our solutions for a specified period of time with no payment to us. Our current licensing agreements typically require the customer to pay a license fee attributable to the software components and the application solution and upon shipment of these items to the customer, although we have sometimes waived the up-front fee.

Customers cannot simply license our solutions and begin using them immediately in their businesses. Making our solutions work with a particular customer’s application may be a complex, expensive and, in certain cases, an ultimately unsuccessful process. This process may also require the customer to make significant commitments of time and money. Based on discussions with our customers, we believe that a customer’s required cycle of testing, internal approval and network modifications can reasonably take between six and nine months or longer. Therefore, we expect our sales cycle, or the time between entering into an agreement and when we begin to receive and recognize revenue, to be six to nine months or longer. Also, the amount of revenue can be very limited until the customer’s product is made generally available and adopted. Our sales are also subject to significant risks over which we have little or no control, including customers’ budgetary constraints and internal acceptance procedures regarding security-related matters. To mitigate the risk of our current software licensing business model we are currently exploring the viability of a managed security service provider business model to supply our offerings through subscription-based licensing arrangements.

We lack experience in sales and marketing, and we depend on our relationships with more established corporations to assist in selling and marketing our products. We have limited sales and marketing experience and limited money to fund marketing. A significant part of our business strategy is to form strategic relationships with more established companies to expose our solutions to a larger customer base than we could reach through a direct sales and marketing force. Our existing relationships have not resulted in any significant revenues to date and may not result in any revenues in the future.

As a result of our emphasis on these relationships, our success will partially depend on both the ultimate success of the third parties with whom we have these relationships and the ability of these third parties to market our products and services successfully.

We cannot provide assurance that we will be able to enter into additional, or maintain our existing, strategic relationships on commercially reasonable terms, if at all. Our failure to do so would require us to devote substantially more resources to the distribution, sales and marketing of our products and services. Also, these strategic relationships do not afford us any exclusive marketing or distribution rights. The third parties may reduce their commitments to us in the future or pursue alternative technologies.

The nature of our products subjects us to product liability risks, potential lost revenues and adverse publicity in the event of product failure. Our customers may rely on our products to prevent unauthorized access to computer networks. Malfunctions or design defects of our products could:

•

cause interruptions, delays or cessation of services to our customers,

•

result in product returns,

•

result in liability for damages,

•

adversely affect the market’s perception of the security offered by our product, resulting in a lack of demand for our products, or

•

require us to make significant expenditures of capital or other resources to alleviate the problem.

Our license agreements may not be adequate to limit our liability. A large number of claims by our customers could subject us to significant liability as well as limit the demand for our solutions and products. In most cases our license and support agreements attempt to limit our liability to the total amount of the licensing and support fees paid during the twelve-month period preceding an alleged error in or failure of our software. This contractual provision may not always be enforceable. Courts have held that contractual limitations of liability of this type, or the “shrink-wrap licenses” in which they are sometimes embodied, are unenforceable because the licensee does not sign them. If these contract provisions limiting our liability are not enforceable, we could be obligated to pay significant damages resulting from customer claims.

If computer hackers find ways to circumvent our products, our products would not perform their essential function. Any compromise of the security offered by our products, in a single incident or a series of incidents, would make our products less attractive to our customers. Software error or failure may result from a hacker seeking unauthorized access to a computer network. The methods used by hackers are evolving rapidly and generally are not recognized until they are launched against one or more systems. We are unable to anticipate hackers’ tactics. The publicity surrounding any security breaches could adversely affect the public perception of the security offered by our authentication and authorization products and make it more difficult for us to sell our products.

We might not always be able to enforce our intellectual property rights. Our success depends significantly upon our proprietary technology, and our means of protecting our proprietary and intellectual property rights may not be adequate. We rely on a combination of patent and trademark laws, trade secrets, confidentiality agreements and contractual provisions to protect our proprietary rights. We have two U.S. patents, which will be in effect until at least August 22, 2017, and three patents granted in Israel in effect until 2017 and 2021, as well as 13 applications pending in Israel, the United States and Canada. We cannot provide assurance that any of our applications will be approved, that any new patents will be issued, that we will develop proprietary products or technologies that are subject to patent, that any issued patent will provide us with any competitive advantages or will not be challenged by third parties. Furthermore, we cannot provide assurance that the patents of others will not have a material adverse effect on our business and operating results. There is also a risk that our competitors will independently develop similar technology, duplicate our products or design around our patents or other intellectual property rights.

If our technology or products were determined to infringe upon the rights of others, we would be required to obtain licenses to use that technology. If we are not able to obtain a license in a timely manner on acceptable terms or at all, we may have to stop producing our product until we can develop an alternative that does not infringe the rights of others.

Patent disputes are common in technology-related industries. We cannot provide assurance that we will have the financial resources to enforce or defend a patent infringement or proprietary rights action. As the number of products and competitors in our target markets grows, the likelihood of infringement claims also increases. Any claims or litigation may be time-consuming and costly, cause product shipment delays or require us to redesign our product or require us to enter into royalty or licensing agreements. Any of these events could have a material adverse effect on our business and operating results. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to use our proprietary information and software. In addition, the laws of some foreign countries do not protect proprietary and intellectual property rights to as great an exten t as do the laws of Canada and the United States.

Changes in the export regulation of encryption-based technologies may restrict our ability to sell or license our products. Our products are subject to export controls under Canadian and U.S. laws and regulations. These laws and regulations may be revised from time to time in ways that may materially and adversely affect our ability to sell our products abroad or to make products available for sale or license via international computer networks such as the Internet, although pursuant to an international treaty, a number of countries have relaxed, or are in the process of relaxing, their export rules as applicable to products licensed by us. Canadian and U.S. government controls on the export of encryption technologies which we license from third parties and which are embedded in our products may, if subject to revision, be amended and subsequently restrict our ability to freely export our products . As a result, foreign competitors subject to less stringent export controls on their products may be able to compete more effectively than we can in the global information and computer security market.

Our articles of incorporation authorize us to issue an unlimited number of common shares, which could result in dilution to our shareholders. Subject to regulatory and/or shareholder approval, shareholders may experience dilution or limitations in takeover attempts because our articles of incorporation allow us to issue an unlimited number of common shares. Our shareholders have no right to purchase additional common shares when we issue new shares. As of December 31, 2005, we had 24,316,691 common shares issued and outstanding.

If our common shares should become ineligible for continued quotation on the OTC BB or a public trading market does not continue for any reason, holders of our common shares may have difficulty selling their shares.Our common shares became ineligible for continued quotation on the NASDAQ SmallCap Market and are now trading on the Over the Counter Bulletin Board; therefore holders of our common shares will have difficulty selling their shares. Our common shares were quoted on the NASDAQ SmallCap Market from June 1995 through late April 2003.

Our common shares may continue to be penny stock, which may adversely affect the liquidity of our common shares. The United States Securities and Exchange Commission has adopted regulations that define a penny stock to be any equity security that has a market price, as defined in those regulations, of less than $5.00 per share, subject to certain exceptions. Our common shares are currently penny stock.

Generally, for any transaction involving a penny stock, a broker-dealer is required to deliver, prior to the transaction, a disclosure schedule relating to the penny stock market as well as disclosure concerning, among other things, the commissions payable, current quotations for the securities and information on the limited market in penny stocks.

The liquidity of our common shares may be materially and adversely affected if our common shares continue to be penny stock due to the administration requirements imposed by these rules.

It may be difficult for our shareholders to enforce civil liabilities under the U.S. federal securities laws because we are incorporated in Canada. We are incorporated under Canadian law and the majority of our directors and executive officers are Canadian citizens or residents. All, or a substantial portion, of these persons’ assets and substantially all of our assets are located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon those persons or us or to enforce against them judgments of U.S. courts predicated upon civil liabilities under U.S. federal or state securities laws. Also, there is uncertainty as to the enforceability in Canada, in original actions or in actions for enforcement of judgments of the U.S. courts, of civil liabilities predicated upon U.S. federal or state securities laws.

We may be treated as a passive foreign investment company, which would have adverse tax consequences for our U.S. shareholders. We may be treated as a passive foreign investment company, or a PFIC. While we do not believe that we should be treated as a PFIC, whether we are treated as a PFIC depends on questions of fact concerning our assets and revenues. Accordingly, we cannot assure you that we will not be treated as a PFIC. If we were to be treated as a PFIC, there could be material adverse tax consequences to U.S. holders of our common shares.

Industry Background

In recent years, the mobile data industry has been growing on many fronts. We believe the worldwide growth of the mobile data industry is being propelled by the explosive growth of the Internet and the consequent demand for mobile data access to the Internet, high penetration rates for users of mobile telephones, intense price competition among mobile network operators and the emergence of worldwide standards for mobile data communications.

Security has and will continue to be a major concern for the mobile data community. The increasing number of consumers and businesses that expect the ability to securely access confidential information and conduct transactions wirelessly has created the interest and demand for mobile device security.

The mobile data market is not readily adaptable to its networks, applications and devices used within existing wired solutions. Mobile data networks are fundamentally different from wired networks. In wired networks, the Intel chip in a PC is the common device platform, Microsoft Windows is the dominant operating system and the browser is the common graphical user interface. In wired networks, data and content reside largely in databases, and data is extracted by the user on a simplified query basis using search engines - the user must either find or know where to get the information for which he or she is looking.

Mobile data networks currently have no such standards for client platforms, operating systems or user interfaces. The mobile device may be a PDA, a two-way pager, intelligent mobile device or a smart phone. Multiple operating systems are being employed.

Mobile industry standards are emerging, and we are a member and contributor to many of the standard-setting bodies. One of the main standards setting forums is the Open Mobile Alliance (formerly the WAP or Wireless Application Protocol Forum). The objective of this association is to develop standards intended to bring highly-optimized Internet content to mobile devices by creating global mobile data protocol specifications and standards that work across all mobile network technologies. In addition to the Open Mobile Alliance, we are members of the initiative for Open AuTHentication (also known as OATH) an industry-wide collaboration to develop an open reference architecture by leveraging existing open standards for the universal adoption of strong authentication and Liberty Alliance Project an open body working to address the technical, business, and policy challenges surrounding identity and web services.

Need For Secure Transactions Supported By Strong Authentication

The openness and accessibility that have stimulated the adoption and growth of the Internet and mobile and wired public and private networks, also create threats to the authenticity, privacy and integrity of information that is transmitted across or stored on the networks. Well-publicized Internet fraud experienced by on-line companies and attacks resulting in overloading of popular e-business web sites by hackers and ‘phishing’ experts have highlighted the need for improved user authentication. Identity theft is the fastest growing types of consumer fraud. The Federal Trade Commission in the United States has estimated during 2003, almost ten million Americans discovered they were victims of identity theft with a total cost to business and consumers approaching $50 billion. Enhanced user authentication – commonly known as strong authentication – is the next wave of security enablers to curb the rise in identity theft. The sec urity risks associated with personal communications and commercial transactions over the Internet, and over mobile and wired public and private networks, have accentuated the need for strong authentication solutions that protect user identity, data and devices.

In order to further define and deliver to the market needs for strong authentication solutions, the initiative for Open AuTHentication (OATH) was founded in February 2004 by Verisign including a host leading global information and communication technology industry companies as charter members: IBM, Gemplus, Entrust, Diversinet, VASCO, SafeNet and others. According to OATH, strong authentication connotes a stringent level of security that combines a user ID with a software or hardware ‘token’ to form a unique device that validates a user’s identity when accessing a software application or network. It represents a foundational element of trusted networks where multiple business partners can securely share confidential information. Online identities secured only by static passwords can be exploited, resulting in identity theft or compromised systems. Existing two-factor authentication approaches, while more effective, are often expensive and complex, and their lack of interoperability poses significant barriers to adoption. An industry-wide collaborative effort to promote Open Strong Authentication will remove these barriers and broaden enterprises’ use of the Internet to communicate, collaborate, and conduct commerce in new ways.

Market Acceptance of Strong Authentication

A wide range of products and services have been introduced to address strong authentication requirements for wired applications and services. For example, products such as password tokens, smart cards and USB authenticators, which limit network access only to users having recognized addresses or entering recognized passwords, provide access control by providing One-Time-Passwords (OTPs). These OTP products are generally limited in their flexibility, user convenience and are expensive to the general enterprise and consumer markets. Globally, there are over 25 million authentication ‘tokens’ in the market, as stated by vendors RSA Security and VASCO, with the average end user cost per token of $40 per unit. This cost does not include system and server fees associated with validating the identity of the user as well as backend integration to the application and/or service provider.

Business to Consumer (B2C) online sales in 2003 were $96 billion, but most of these sales were authenticated by a simple password. We believe that globally, the enterprise and consumer mass markets have not yet adopted strong authentication because of the associated high-costs for the ‘tokens’ and because of the inconvenience of carrying multiple authentication devices to remotely access Internet lifestyle communities such as banking, wagering, associations, corporate information and public sector services. For strong authentication to take hold for the mass market, each individual user would be required to carry, and pay for, one ‘token’ for each access point. We believe a soft token capable of addressing multiple access points created within, or delivered to, a mobile device, will increase the acceptance for strong authentication.

Need for Mobile Authentication Services

We believe that as mobile devices proliferate in the marketplace and become both smarter and connected to the Internet the requirements to authenticate the device and the users become critical. The identity of the individual must be maintained and protected in order to facilitate transactions over the wireless network and the Internet. Whether an individual is downloading a ring-tone to their phone, requesting private health data from a hospital database or simply expecting their email to be secure, authentication services are essential in a mobile world.

The prevention of fraud, the ability to thwart phishing schemes, the need to protect identities and private information are all dependent upon authentication of individuals using mobile devices and their associated services.

Market Size

Mobile devices are becoming pervasive in many parts of the world. Today there are 1.5 billion wireless phones worldwide with predictions of subscribers reaching three billion by 2010, as networks grow and prices for handsets continue to drop according to Goldman Sachs Research. Over 700 mobile network operators worldwide contribute to subscriber growth and will be seeking to retain subscribers through the provision of innovative authentication services.

Our products and services target wireless subscribers worldwide by enhancing the mobile device function to provide both a trusted identity and the capability to generate and receive One-Time Passwords.

Our MobiSecure product also operates on Windows-based personal computers, of which there are approximately 500 million deployed around the world.

Financial Institutions worldwide are concerned with the weaknesses inherent in simple passwords as single factor authentication. According to Soleil Equity Research, approximately 50,000 banks worldwide have recognized the need for strong authentication and have begun to offer limited wireless device One-Time Password delivery.

Demand Drivers

We believe that the four significant drivers of demand for mobile-optimized strong authentication products and services are as follows:

Rise of phishing and identity theft over the Internet

Consumers are becoming less trustful of Internet online systems for banking and commerce as identity theft and phishing attacks (sending an e-mail to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft.) on consumers increase. We believe consumers are looking for more secure means of identifying themselves to financial institutions, online commerce suppliers and online service providers. The acceptance of One-Time Password token generators will enter the consumer market as the banking industry and e-commerce providers seek solutions to protect their customer transactions.

Rise of Federated Identity Networks

Federated identity networks are increasing to help businesses establish a virtual network, or “circle of trust,” through authentication (of an identity) and single sign-on across domains. The vision is that users and their identities are grouped and trusted across many boundaries such as those with partners, customers and third-party contractors.

The Liberty Alliance, the leading identity network, is setting standards for the implementation of federated networks, and we believe the Liberty Alliance framework is emerging as a ‘de facto’ standard for mobile identity based data services. Within Liberty, member companies collectively represent close to 400 million mobile subscribers, more than half of the mobile devices in the market, some 80% of all Subscriber Identity Modules (SIM) and approximately 55% of the mobile network infrastructure providers.

Strong authentication is critical to the success of all federated networks however, as mobile network operators become identity providers in federated networks, mobile optimized authentication must be integrated on the mobile device in order to prevent identity theft and fraud.

Mandated Government Regulation

Enterprises are looking toward stronger authentication methods in order to track and control who has access to what information in order to comply with demanding regulations such as the Sarbanes-Oxley Act and the Health Insurance Portability and Accountability Act. Hackers cannot be tolerated when corporations are legally responsible to protect the privacy of the data under their control.

Lack of security as an impediment to m-commerce and e-commerce growth

Security is often regarded as the primary impediment to the mainstream adoption of the Internet as a business tool. Given the importance attached to the Internet and mobile networks and the related potential for cost reduction and revenue generation, the issue of security becomes one of fundamental need and importance.

Much publicized security incidents including misappropriation of personal data on smart phones, high profile identity theft, and the continued rise in phishing attacks have provided a growing perception among many consumers that there is a risk involved in transmitting information via mobile networks and the Internet. We believe electronic commerce, both Internet and mobile based will benefit from improved mobile authentication services that correctly identify users and reliably encrypt data over mobile networks.

Strategy

We strive to be a leader in providing mobile-optimized strong authentication products, solutions and services to protect mobile user identity, data and devices over mobile data networks and other networks, including corporate networks, telecommunications systems and the Internet.

The key elements of our strategy to achieve this objective include the following:

Target emerging strong authentication markets. Our sales and marketing activities are primarily targeted at emerging Internet markets to protect consumer, enterprise, and commerce high-value applications with mobile assisted One-Time Password token solutions, in addition to more traditional forms of personal communications and commercial transactions over mobile data networks. Within these markets, our customers and partners include device manufacturers, network infrastructure manufacturers, application developers, certificate authorities and mobile network operators. Our business plan is dependent of the cooperation of numerous parties to a transaction.

Expand strategic relationships. We have formed relationships in the areas of sales, marketing and technology with industry leaders, and expect to continue to form such relationships in the future, to encourage widespread acceptance of our mobile authentication products, solutions and services. These include relationships with such companies as:

VeriSign

Microsoft

RSA Security

Research In Motion

Magna

Symbian

Rogers Wireless

PalmSource

Maintain what we believe to be a leadership position in terms of research and development of technology. In late 1996, we acquired technology that consists of concepts and methods that relate to automatic and safe public information communication systems and methods for secure distribution of information. We have invested, and intend to continue to invest, significantly in the development of our technology. We will base future development of our technology on mobile device security market requirements. In January 1999, we were issued a patent for this technology by the U.S. Patent and Trademark Office that will be in effect until August 22, 2017. In April 2001 we received an U.S. patent for our technology relating to the handling of permissions. In June 2001 we received an Israeli patent that will be in effect until 2021 for our technology relating to safe communications handshake and d ata transfer. In July 2003, we received a patent from the State of Israel Patent Office for our “System and Method for Reliable Key Transfer”. This patent will be effective until 2021. This system and method provides for an automated method to securely update root certificate authority (CA) keys and certificates (basis for root rollover) and combine domains. On August 5, 2003, we received a trademark from the U.S. Patent and Trademark Office for our Diversinet logo. This trademark will be effective until 2013. On November 2, 2003, we received a patent from the State of Israel Patent Office for our “System and Method for Handling Permits”. This patent will be effective until 2017. The patented technology provides for a unique permit separation model that enhances the security and privacy of wired and wireless e-commerce systems by improving the management of personal privileges in advanced PKI security environments.

Build awareness of the Diversinet brand. One of our main goals is to establish our brand as a leader for mobile authentication products, solutions and services for all transactions over mobile data networks. We plan to achieve this goal through a variety of programs that will generate brand awareness. These include regular press and investor sessions, an ongoing pro-active speaking program by senior management and regular interaction with major market influencers.

Strengthening our Presence in the Canadian, US and Hong Kong Markets. We believe the Canadian and U.S. markets will be active and growing markets for our mobile authentication products, solutions and services. To strengthen our position in these important markets we are focusing our sales and marketing efforts to align our resources with strategic partners in each territory to deliver to local market needs.

Products and Services

We believe our technology and approach to mobile authentication services have several distinct advantages over existing security methods. Most notably, our solutions were developed specifically for the mobile environment. Our mobile-optimized technology minimizes demands placed on scarce device resources such as processor and memory, and as a result assists in conserving battery life. Our technology also minimizes the amount of data sent over the network and the number of steps required to achieve a secure connection, which optimizes consumer network resources

We develop, market and distribute a complimentary product and service suite: Diversinet MobiSecure Client and Diversinet MobiSecure Authentication Services together provide, what we believe to be, a comprehensive security solution with a focus on mobile applications residing on Palm, RIM, Symbian, Microsoft and Java-based operating systems; mobile browser-based devices; and GSM/SIM (Subscriber Identity Module) based devices.

Our products and services are designed to address the unique needs of mobile devices, networks and applications. When integrated with specific applications, our products enable mobile users to effectively manage secure communications and transactions across mobile data networks.

Diversinet MobiSecure Client

The MobiSecure Client is a mobile device resident software tool designed to support applications running on the mobile device with an accessible security service package. The primary product objective is to enhance mobile device resident applications to utilize a series of mobile security functions supporting Authentication, Privacy, Integrity and Non-repudiation.

The MobiSecure Client package contains several initial applications. These include a user One-Time Password (OTP) application as well as appropriate One-Time Password browser plug-ins to allow One-Time Passwords to be generated automatically during browser sessions.

Diversinet MobiSecure SDK

The Diversinet MobiSecure SDK provides mobile application developers with a suite of security Application Program Interface to integrate the Diversinet MobiSecure Client software and service bureau infrastructure across a range of mobile device platforms, Internet and mobile data networks for secure personal communication and commercial transactions

The Application Program Interfaces included with the SDK as designed to link server-side components with the client devices based upon a device class scheme, thereby simplifying the design work of application developers.

Diversinet MobiSecure Authentication Services

The Diversinet MobiSecure Authentication service will operate as a hosted application service bureau service bureau.

MobiSecure Authentication services will provide the basis for both supporting the provisioning of the Mobile Secure Client and the delivery of an SMS two-factor authentication service.

Service Applications

Our Diversinet MobiSecure Client and Authentication Services when launched will be primarily support a wide variety of emerging secure personal communications and commercial transaction applications in the financial, enterprise, consumer and gaming industries for both wired Internet and mobile Internet networks.

The generation of one-time passwords by the MobiSecure Client resident on smart phones or delivery of One-Time Passwords via the Diversinet MobiSecure Authentication Services will address the need for two-factor strong authentication. This application eliminates the need for hardware tokens and addresses a need for multiple tokens delivered on the same device.

Product and Service Development

Our engineering group is focused on developing core technologies and enhancements to existing product lines to maintain and extend what we believe to be our technology and product leadership position. More specifically, the group is currently focused on the development of additional features for Diversinet MobiSecure software and the Mobile Secure Authentication Services the features of which will be assessed in terms of market demand and competition.

The product will continue to develop with a focus on the unique characteristics of the mobile market and enhancements to Over-the-Air provisioning. Our engineering group reviews relevant proposed industry standards or conventions as they are developed and seeks to make our products compatible with each of them. We participate in industry standard bodies, such as the initiative for OATH, ensuring OATH compliance of our products. Through the Liberty Alliance Project we assist in the development of business guidelines for mobile deployments. Through our membership with the Open Mobile Alliance (OMA) we monitor the activities of others, such as the Internet Engineering Task Force (IETF) and the American National Standards Institute (ANSI).

Consulting Services and Support

We believe that a high level of service and support will be critical to our success and that a close and active customer relationship is important to facilitate rapid implementation of our solutions, assure customer satisfaction and provide us with important information regarding evolving customer requirements. We are in the process of building a Diversinet MobiSecure services group that will provide product integration services, customized engineering support and training to our customers through our channel partners.

Research and Development

We expect that our future success will depend in large part on our ability to continue to maintain what we believe is a leadership position in terms of research and development of technology. Our research and development efforts are focused on developing core technologies and enhancements to existing products and services in order to maintain and extend our technology and product leadership position. We leverage open industry standards and open source initiatives to maintain our pulse on the mobile, security and IT industries.

As of December 31, 2005, our research and development staff consisted of 18 employees (of which 8 hold advanced degrees in science or business). Research and development expenditures were $1.2 million in the fiscal year ended December 31, 2005, $1.2 million in the fiscal year ended December 31, 2004, and $1.3 million in the fiscal year ended December 31, 2003. We expect to spend approximately $1.6 million in fiscal 2006. We believe that timely development of new and enhanced security products is necessary to remain competitive in the marketplace.

Customers

To date, we have executed limited pre-commercial collaboration programs with a wide range of market development partners and customers for mobile authentication services. In addition, we received service revenue for support and maintenance from other service contracts for professional services and solutions.

Competition

Our mobile authentication technology is targeted at the new and rapidly evolving demand for mobile-optimized strong authentication solutions. Although the competitive environment has yet to develop fully, we anticipate that it will be highly competitive, subject to rapid change and significantly affected by new product and service introductions and other market activities by industry participants. We believe we are one of a few companies that currently have mobile authentication services based on the OATH reference architecture available in the mobile device security market that provides an end-to-end solution. There are a number of successful security vendors who have announced their intention to compete in the mobile space. These include RSA, SafeNet, and Entrust. While these competitors have better name recognition in general, we are striving to become a leading brand in mobile authentication services t oday. We also anticipate competition from a number of other larger and smaller companies that provide other security solutions. Many of our competitors and potential competitors have significantly greater resources than we have.

The principal competitive factors affecting the market for mobile authentication services include technical features, ease of use, reliability, level of security, scalability, customer service and support and price. There are also significant technical challenges that are unique to the mobile environment, including constraints in device processing and storage capabilities, and network throughput limitations. We believe our products have been optimized for this unique and technically challenging environment. Our future success will largely depend on our ability to make our products available to serve the rapidly growing mobile authentication services market, rather than taking market share away from competitors.

Regulatory Matters

Some of our products are subject to special export restrictions administered by the Canadian government and are also subject to import restrictions and/or use restrictions imposed by countries such as the United States, although pursuant to a recent international treaty, a number of countries have relaxed, or are in the process of relaxing, their export rules as applicable to products of the type licensed by us. Consequently, our ability to export our products to destinations outside of Canada is subject to a variety of government approvals or licensing requirements. These export controls may also restrict our ability to make some products available for sale via international computer networks such as the Internet. Re-export of the products between countries other than the United States and Canada may be subject to the export control laws of those countries in addition to those provisions of Canadian export control la ws that apply to re-exported goods. In light of these restrictions, depending on the country of destination, industry sector and/or end-user, some of our products made available abroad may contain significantly weaker encryption capabilities than those available to customers in Canada, and there can be no assurance that we will continue to be able to export our products to any destinations outside of Canada. Such restrictions could potentially have an adverse effect on our business, financial condition and results of operations.

Intellectual Property

We rely on a combination of patent, trade secret and trademark laws, non-disclosure agreements and contractual provisions to establish and protect our proprietary rights. We also seek to protect our trade secrets and other proprietary information through license agreements with customers and suppliers, as well as non-disclosure and non-competition agreements with employees and consultants.

On January 26, 1999, we received a patent from the U.S. Patent and Trademark Office for our “Method for Safe Communication” which will be in effect until August 22, 2017. This method consists of the safe distribution of encryption keys, including a known public and secret private key, and establishes a secure link between computer users who reside at separate locations and who have had no previous secure communications.

On April 10, 2001, we received a patent from the U.S. Patent and Trademark Office for our “System and Method for Handling Permits”. The patented technology provides for a unique permit separation model that enhances the security and privacy of wired and wireless e-commerce systems by improving the management of personal privileges in advanced PKI security environments.

On June 20, 2001, we received a patent from the State of Israel Patent Office for our “Apparatus and Method for Safe Communication Handshake and Data Transfer”. This patent will be effective until 2021. This apparatus and method provides for the safe distribution of encryption keys, including a known public and secret private key, and establishes a secure link between computer users who reside at separate locations and who have had no previous secure communications.

On July 11, 2003, we received a patent from the State of Israel Patent Office for our “System and Method for Reliable Key Transfer”. This patent will be effective until 2021. This system and method provides for an automated method to securely update root certificate authority keys and certificates (basis for root rollover) and combine domains.

On August 5, 2003, we received a trademark from the U.S. Patent and Trademark Office for our Diversinet logo. This trademark will be effective until 2013.

On November 2, 2003, we received a patent from the State of Israel Patent Office for our “System and Method for Handling Permits”. This patent will be effective until 2017. The patented technology provides for a unique permit separation model that enhances the security and privacy of wired and wireless e-commerce systems by improving the management of personal privileges in advanced PKI security environments.

Applications for thirteen other patents have also been submitted in Israel and Canada based on the same concept for which the United States patent was granted, as well as other concepts.

We have registered the name “Passport Certificate Server” with the Canadian Trademark Office. We have also applied to register as trademarks with the United States Patent and Trademark Office and/or the Canadian Trademark Office the names “Diversinet”, “Passport Certificate Server” and “Passport Authorization Product”, but there can be no assurance that these trademarks will be successfully registered.

We continue to seek patent and trademark protection where appropriate.

Marketing and Sales

Marketing

Our marketing efforts will support our two primary marketing objectives:

(i)

increasing awareness through building the Diversinet brand; and

(ii)

generating sales leads in our target markets. Our efforts to increase awareness and build our brand will entail gaining positive coverage in targeted trade and business publications and establishing and developing relationships with analysts from market influencers, such as Ovum and Gartner. We will pursue the generation of sales leads through the implementation of programs such as web marketing, direct mail, active participation in targeted events, and cooperative marketing activities in support of channel partners.

Sales

We offer our mobile authentication products, solutions and services globally to security providers, mobile network operators and application providers employing several sales models to target our intended markets.

We believe that our coverage of these markets by our sales team through our partners is necessary to pursue our targeted customer base, which is still in the early stage of high-value secure mobile application deployment and testing. Our customer focus is in providing mobile authentication solutions to security providers, mobile network operators and application providers, both directly and through licensed distribution channels. We are also exploring OEM relationships for the private branding of our products, solutions and services.

The current sales and implementation cycle for our mobile authentication products, solutions and services is approximately six months and consists of four phases:

•

Initial contact and customer education/qualification

•

Pilot proof of concept

•

Early deployment testing

•

Phased production rollout

Seasonality

Seasonality does not affect our main business; our business generally does not fluctuate based solely on the time of year.

Raw Materials and Suppliers

We do not use a significant amount of raw materials in our business. Substantially all of the raw materials that we use in our business are either freely available, such as office supplies, or are easily available to us at reasonable prices, such as computer hardware and software.

Organizational Structure

In January 2003, we acquired 100% ownership of DSS, a professional services company, in Fremont California. In February 2005 DSS completed an asset sale agreement whereby it sold the majority of its current assets, capital assets, current liabilities, consultant and customer accounts for $250,000. As part of the agreement, Diversinet is entitled to a five year annual fee of up to $120,000 per year based on the purchaser meeting certain gross profit and net profit criteria. In September 2003, we acquired 100% ownership of Caradas, a smart card-based application security company headquartered just outside Boston, Massachusetts.

During 2001, we entered into an agreement with an Asian company to establish a joint venture to conduct certain of our Asian activities. Each party holds a 50% interest in the joint venture, Atria Limited (formerly Diversinet Hong Kong Limited). During the second quarter of 2004, we received notification from the other joint venture partner of their intent to terminate the joint venture agreement and wind up the joint venture. During the fourth quarter of 2004 we increased our depreciation charge by $145,000 (and reducing our capital assets cost base by $330,000 and our accumulated depreciation and amortization for our capital assets by $185,000) for our joint venture assets in recognition that we are in the process of winding up the joint venture.

We have five inactive wholly-owned subsidiaries, Diversinet Corporation of America, incorporated in Delaware, Diversinet Inc., an Ontario corporation which was formed on November 20, 1996; Instant Publisher Ltd., a Barbados corporation formed on December 2, 1993; Diversinet (Israel) Ltd., an Israeli corporation; and DSS Software Technologies, incorporated in California.

4-D.

Property, Plant and Equipment

Our head office is located in leased premises of approximately 6,200 square feet at 2225 Sheppard Avenue East, Suite 1801, Toronto, Canada M2J 5C2. During 2003 we sublet the 17th floor (13,497 sq. ft.) and moved to the smaller space on the 18th floor.

The lease for our head office expires in August 2006. We currently expect to be able to extend the terms of expiring leases or to find replacement facilities on reasonable terms.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this annual report. Except for historical information, the following discussion contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements involve risks and uncertainties. Such forward-looking statements include, among others, those statements including the words, “expects”, “anticipates”, “intends”, “believes”, and similar language. Our actual results may differ significantly from those projected in the forward-looking statements. Factors that might cause future results to differ materially from those discussed in the forward-looking statements include, but are not limited to, those discussed in “Risk Factors” in Item 3-D. of this annual report.

We have incurred operating losses in each of the last five fiscal years due to losses from our continuing operations of developing security products and our discontinued operations of developing and marketing the IPS 950 instant color digital printing system. We have sustained our business during this period through the sale of common shares in a series of private placements. We cannot provide assurance that we will be able to raise sufficient funds in the future to sustain our operations.

Operating Results

Overview

We are a mobile device security software product and service company that develops, markets and distributes mobile authentication solutions that provide for the secure transmission of data over mobile networks. Our solution encompasses all aspects of communication and commercial transaction security requirements, covering the authentication and authorization of individuals involved, the integrity of the information being sent and the non-repudiation or legalization of the transaction.

We believe we are a pioneer in providing mobile device security products for the secure transmission of data over mobile networks and are striving to become the leading provider of mobile authentication services. Our strategy to achieve this objective involves: targeting emerging mobile data and messaging markets, expanding strategic partnerships and sales channel relationships, maintaining a leadership position in terms of products and services, research and development, and building awareness of the Diversinet brand.

We develop, license, service and support the Diversinet MobiSecure suite of mobile authentication products, solutions and services. Diversinet MobiSecure Client provides the ability to support multiple mobile authentication solutions and service applications across a wide range of mobile device platforms. Based on our intellectual property, patents and Passport Trust Platform™ developed over the last seven years, we have consolidated its core technology capabilities to an application service provider business model and rebranded our offerings as the Diversinet MobiSecure suite of mobile authentication products, solutions and services. As an application service provider, Diversinet products, solutions and services allow companies to deploy the robust mobile-optimized strong authentication infrastructure needed for trusted exchange of sensitive information over mobile data networks quickly and cost-effectively. This enables compan ies to reduce the time-to-market for delivery of new secure mobile data applications and business services.

During 2002, the average U.S. - Canadian dollar rate was 1.57. During 2003, the average U.S. - Canadian dollar rate had dropped to 1.40, causing our Canadian dollar expenditures to increase relative to the U.S. dollar. During 2004, the average US – Canadian dollar rate was 1.30, causing our Canadian dollar expenditures to again increase relative to the US dollar. During 2005, the average U.S. – Canadian dollar rate was 1.16, causing our Canadian dollar expenditures to increase relative to the U.S. dollar. However with the inclusion of Caradas for the full year in 2004, leading to a higher percentage of US denominated expenditures, our overall Canadian dollar expenditures as a percentage of total expenditures dropped.

Operating Results

Unaudited quarter ended December 31, 2005 compared to the unaudited quarter ended December 31, 2004

Revenue

For the quarter ending December 31, 2005, we reported revenue of $159,000 compared to $419,000 for the quarter ended December 31, 2004. During the quarter, we generated 100% (100% in 2004) from consulting services and nil (nil in 2004) from licensing. The lower revenue for the 2005 quarter was due to a reduction in the Caradas revenues of approximately $254,000. During the fourth quarter of 2005, Caradas revenues were $120,000 (2004 - $374,000) of which $47,000 was from deferred revenues.

Cost of sales

Cost of sales were $13,000 for the quarter ended December 31, 2005 compared to $267,000 for the same quarter in 2004. During the fourth quarter of 2005, revenue included $47,000 from deferred revenues for which the costs incurred were included in the 2004 cost of sales.

Expenses

Research and development expenses were $310,000 for the quarter ended December 31, 2005 compared to $210,000 for the similar period of 2004. During the fourth quarter of 2004, we received a net amount of $141,000 relating to investment tax credits for R&D work done in 2003 and the two month stub period in 2002. Sales and marketing expenses were $354,000 for the quarter ended December 31, 2005 compared to $138,000 for the similar period of 2004. The Q4 2005 results include severance costs as we realigned the sales and marketing team. Throughout the quarter the average number of employees in this department was greater by one. This resulted in remuneration, travel and human resource cost being greater by $144,000. Public and media relations expenses were increased by $34,000 over Q4 2004. General and administrative expenses were $503,000 for the quarter ended December 31, 2005 compared to $525,000 for the similar p eriod of 2004. The 2005 quarter includes $177,000 in stock-based compensation expense, compared to $256,000 for the similar period in 2004.

Depreciation and amortization

Depreciation and amortization expense was $48,000 for the quarter ended December 31, 2005 compared to $332,000 for the similar period of 2004. During the fourth quarter of 2004, we increased our depreciation charge by $145,000 for our joint venture assets. The expense for the fourth quarter of 2004 also included $130,000 relating to amortization of customer assets and purchased technology. These assets were written off in the third quarter of 2005. The remaining variance is the result of applying our rates to a declining net asset balance.

Other Income

We reported net income from discontinued operations of $28,000 for the quarter ended December 31, 2005 compared to a loss of $592,000 in the prior year’s comparative period.

Net Loss

We reported a net loss of $1,030,000 for the quarter ended December 31, 2005 and $4,166,000 for the quarter ended December 31, 2004. The quarterly 2004 loss includes $2,500,000 related to a goodwill impairment charge for Caradas. The loss per share was $(0.05) for the quarter ended December 31, 2005 compared to $(0.31) for the December quarter of 2004.

Year ended December 31, 2005 compared to year ended December 31, 2004

Revenue

For the year ending December 31, 2005 and 2004, we reported revenue of $1,101,000 and $2,603,000 respectively. We generated 73% (90% in 2004) of our revenues from the United States, 18% (2% in 2004) from the Asia Pacific region, 9% (4% in 2004) from Canada and nil (4% in 2004) from other areas during the year ended December 31, 2005. During this year, we generated 100% (87% in 2004) from consulting services and nil (13% in 2004) from licensing. The lower revenue for 2005 was due to a reduction in the Caradas revenues of approximately $1.5 million. During the third quarter of 2005 we received notice from one of our customers that they would not be renewing our contract to provide test lab services. This contract represented $479,000 in 2005 revenues ($355,000 in 2004). In 2004, we received $195,000 from a license sale of our Connexus Client software. In January 2005 Diversinet began to focus on the evolving protection and trust needs of mobile users. This shift resulted in a decrease in our US professional services in the amount of $833,000. These financial results reflect this shift in focus and the time required to build up a customer base under this new strategy and a rebuilding of the sales and marketing strategy of the company.

During 2005, 67% (64% in 2004) of our revenue came from two customers. While we are endeavoring to increase our customer base, the market that we operate in is still in an evolving stage and our revenue is still quite small. Therefore, it is reasonable to expect that our revenue may continue to be concentrated among relatively few customers for the near future.

Cost of sales

Cost of sales were $563,000 (gross margin of 49%) for the year ended December 31, 2005 compared to $1,427,000 (gross margin of 45%) for 2004. This represents the direct costs associated for completing the software solutions and consulting services revenue. The increase in the gross margins for 2005 are due in part to a $200,000 higher margin test lab project.

Expenses

Research and development expenses were $1,242,000 for the year ended December 31, 2005 compared to $1,154,000 for 2004. During 2004 we received $141,000 relating to investment tax credits for R&D work done in 2003 and the two month stub period in 2002.

Sales and marketing expenses were $1,290,000 for the year ended December 31, 2005 compared to $1,195,000 for 2004. The increase in sales and marketing is largely due to the implementation of the new strategy of the evolving protection and trust needs of mobile users started in January 2005.

General and administrative expenses were $2,301,000 for the year ended December 31, 2005 compared to $2,369,000 for 2004. Included in the December 31, 2005 general and administrative expenses is $986,000 ($761,000 for 2004) relating to stock-based compensation expenses. Remuneration and travel increased $146,000 over 2004 as a result of the addition to our executive team of a President offset by the reduction of an employee at head office. Professional fees decreased by $353,000 over 2004 due to non-recurring legal settlements and consulting services which were not incurred in 2005. Two large accounts were written off in 2004 resulting in bad debt charges of $85,000 (2005 for $0). Rent expense increased to $158,000 ($119,000 for 2004) relating to our head office in Toronto, Canada.

Depreciation and amortization

Depreciation and amortization expense was $540,000 for the year ended December 31, 2005 compared to $920,000 for 2004. During the fourth quarter of 2004 we increased our depreciation charge by $145,000 for our joint venture assets in recognition that we were in the process of winding up the joint venture. With the sale of the DSS assets in February 2005, we expected to see reduced depreciation and amortization. These figures also include amortization of purchased technology and customer assets acquired on September 1, 2003 in the amount of $126,000 ($189,000 for 2004) and $221,000 ($331,000 for 2004), respectively.

During the third quarter of 2005, we received notice from one of our customers that they would not be renewing our contract to provide test lab services. Therefore, with there being no continuing customers from the September 2003 Caradas purchase and with our new strategy focused on the evolving protection and trust needs of mobile users, we determined that net customer assets were impaired under the fair value based methodology as prescribed under GAAP. We have recorded a customer asset impairment charge of $331,000 (nil- 2004). In consideration of the adverse change noted above, we completed our goodwill impairment testing during the third quarter of 2005. As part of the purchase price calculation, and ultimately affecting the goodwill, the original value attributed to common shares provided in the Caradas acquisition was $3.45 per common share. As the result of the above the fair value of our goodwill exceeded its carrying va lue which results in a $1,895,000 impairment charge in the current year. Caradas has been unable to attract significant new customers in order to generate positive cash flows.

Other Income

Foreign exchange losses were $11,000 for the year ended December 31, 2005 compared to $28,000 for 2004. We earned interest and other income of $32,000 during 2005 compared to $16,000 for 2004 through investing our excess cash.

We reported a loss from discontinued operations of $71,000 for the year ended December 31, 2005 compared to $542,000 for 2004. In February 2005 DSS completed an agreement whereby it sold the majority of its current assets, capital assets, current liabilities, consultant and customer accounts for $250,000. With the sale of the DSS assets, we have included the results of DSS as a single line item (‘discontinued operations’) in the financial statements. During the first quarter of 2005, with the sale of DSS’ assets, goodwill from the acquisition of DSS of $392,000 has been included in determining the loss on disposition.

Net Loss

We reported a net loss for the year ended December 31, 2005 of $7,109,000 compared to $7,517,000 for 2004. These net losses include stock-based compensation expense relating to the issuance of options and warrants of $986,000 and $761,000 during 2005 and 2004 respectively and a goodwill and customer asset impairment charge of $2,225,000 and $2,500,000 for 2005 and 2004 respectively.

Year ended December 31, 2004 compared to year ended December 31, 2003

Revenue

For the year ending December 31, 2004 and December 31, 2003, we reported revenue of $2,603,000 and $1,395,000 respectively. We generated 90% (78% in 2003) of our revenues from the United States, 2% (16% in 2003) from the Asia Pacific region, 4% (1% in 2003) from Canada and 4% (5% in 2003) from other areas during the period ended December 31, 2004. During this period, we generated 87% (76% in 2003) from consulting services and 13% (24% in 2003) from licensing. The higher revenue for 2004 was due to an increase in revenues of $1.2 million through the acquisition of Caradas in September 2003. We are operating in an evolving and unpredictable market and accordingly have and may continue to experience wide fluctuations in our revenues.

During 2004, 64% (67% in 2003) of our revenue came from two customers. While we are endeavoring to increase our customer base, as the market that we operate in is still in an evolving stage and our revenue is still quite small, it is reasonable to expect that our revenue may continue to be concentrated among relatively few customers for the near future.

Cost of sales

Cost of sales were $1,427,000 (or gross margin of 45%) for the year ended December 31, 2004 compared to $417,000 (or gross margin of 70%) for 2003. This represents the direct costs associated with completing the software solutions and consulting services revenue. With the addition of Caradas, licensing revenues (which have a higher gross margin than consulting services) as a percentage of total revenue decreased from 24% in 2003 to 12% in 2004.

Expenses

Research and development expenses were $1,154,000 for the year ended December 31, 2004 compared to $1,276,000 for 2003. The decrease is due in part to further headcount cost reduction measures carried out in during 2004. During the year, we received a net amount of $141,000 relating to investment tax credits for R&D work done in 2003 and the two month stub period in 2002. During 2003 we received $289,000 for 2002 and 2001 and a rebate of retail sales taxes paid in excess in 2001.

Sales and marketing expenses were $1,195,000 for the year ended December 31, 2004 compared to $1,720,000 for 2003. The decrease in sales and marketing is largely due to the headcount cost cutting measures that we undertook in the second quarter of 2004. Included in the December 31, 2003 sales and marketing expenses is $300,000 relating to stock-based compensation expenses. For 2004, all stock-based compensation has been included in general and administrative expenses.

General and administrative expenses were $2,369,000 for the year ended December 31, 2004 compared to $1,731,000 for 2003. Included in the December 31, 2004 general and administrative expenses is $761,000 ($525,000 for 2003) relating to stock-based compensation expenses.

Depreciation and amortization

Depreciation and amortization expense was $920,000 for the year ended December 31, 2004 compared to $663,000 for 2003. During the fourth quarter of 2004 we increased our depreciation charge by $145,000 for our joint venture assets in recognition that we are in the process of winding up the joint venture. These figures also include amortization of purchased technology and customer assets acquired on September 1, 2003 in the amount of $189,000 ($63,000 for 2003) and $331,000 ($110,000 for 2003), respectively.

Other Income

Foreign exchange losses for the year ended December 31, 2004 were $28,000 compared to $324,000 for the year ended December 31, 2003. The 2003 figures include unrealized foreign exchange losses of $477,000 (2004 - $0). Until October 1, 2003, we had historically prepared our consolidated financial statements in Canadian dollars and used the Canadian dollar as our measurement currency. We earned interest and other income of $16,000 during for 2004 compared to $23,000 for 2003 through investing our excess cash. Interest expenses were $0 for the year ended December 31, 2004 compared to $0 for 2003.

During the fourth quarter of 2004, we completed our goodwill impairment test and determined that goodwill of $525,000 as at December 31, 2004 (nil for 2003) relating to DSS and $2,500,000 (nil for 2003) relating to Caradas was impaired under the fair value based methodology as prescribed under GAAP. During fiscal 2004, Caradas was unable to attract significant new customers in order to generate the expected cash flows. DSS lost key management in the first quarter of 2004 and as a result DSS lost several customers over the course of the year. Furthermore, as part of the purchase price calculation, and ultimately affecting the goodwill, the original value attributed to common shares provided in the Caradas acquisition was $3.45 per common share. As the result of the above the fair value of our goodwill exceeded its carrying value which results in an impairment charge in the current period.

We reported a loss from discontinued operations of $541,000 for the year ended December 31, 2004 compared to $246,000 for 2003. During the third quarter of 2004 we settled a dispute with a former shareholder of DSS and received 50,000 Diversinet common shares (with a fair value of $21,000) and the elimination of the promissory note payable of $150,000. This $171,000 gain is offset by the inclusion of $525,000 relating to a goodwill impairment charge for DSS in 2004.

Net Loss

We reported a net loss of $7,517,000 for the year ended December 31, 2004 and $4,959,000 for the year ended December 31, 2003. This net loss for 2004 and 2003 includes stock-based compensation expense relating to the issuance of options and warrants of $761,000 and $825,000 in 2004 and 2003 respectively and a goodwill impairment charge of $2,500,000 and $0 respectively. During the year, we started to report a fair value for stock-based compensation and are including this as an expense. During 2004, we revalued our goodwill from the DSS and Caradas acquisitions, discussed in further detail in this report.

Critical Accounting Policies

The nature of our business is not highly complex, as we operate in one primary business. We develop, market and distribute wireless security infrastructure solutions and identity management solutions and professional services to the enterprise, financial services, government and gaming and wagering marketplace. As part of providing these solutions we perform professional services to install, support and integrate our solutions with other applications. We operate globally in a functional organization. We do not have any off-balance sheet financing, other than operating leases entered into in the normal course of business and we do not actively engage in derivative or hedging transactions. With the acquisitions of DSS and Caradas in 2003, the majority of our revenues and expenses are now in U.S. dollars. Therefore during 2003 we switched our functional currency from Canadian to U.S. dollars. A significant portion of our cash balance is denoted in U.S. dollars.

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Significant estimates are used in determining the allowance for doubtful accounts, the useful lives of intangible assets, including customer assets and purchased technology, and goodwill impairment. In making such estimates and assumptions, management consults with employees knowledgeable in the area; gathers relevant information; where appropriate, seeks advice from qualified third parties; and, makes judgments, which in the opinion at that time, represent fair, balanced and appropriate conservative estimates and assumptions.

In 2004 and 2005, our most complex accounting judgments were made in the areas of revenue recognition and goodwill impairment testing. In 2003, our most complex accounting judgments were made in the areas of revenue recognition. Revenue recognition is expected to continue to be an on-going element of our accounting processes and judgments. Software revenue recognition is expected to continue to be an on-going element of our accounting processes and judgments. Other important accounting policies are described in note 1 to our consolidated financial statements.

Revenue Recognition

We derive our revenue primarily from two sources: sales of products, including hardware and software licenses, and services and professional services. Significant management judgments and estimates must be made and used in connection with the revenue recognized in any reporting period. Material differences may affect the amount and timing of our revenue for any period if our management made different judgments. We have relied upon Statement of Position 97-2, Software Revenue Recognition, EITF 00-21, Accounting of Revenue Arrangements with Multiple Deliverables in developing our revenue recognition policies and CICA 3400 “Revenue”.

Included in our discontinued operations line are revenues from technical consulting services to tier one customers including financial, enterprise and technology companies such as Cisco Systems, Oracle, Sun Microsystems and Wells Fargo in the areas of systems integration, software development, and Enterprise Resource Planning “ERP” and Customer Relationship Management “CRM” implementation. We provided technical consulting services to tier one customers including financial, enterprise and technology companies such as Cisco Systems, Oracle, Sun Microsystems and Wells Fargo in the areas of systems integration, software development, and Enterprise Resource Planning “ERP” and Customer Relationship Management “CRM” implementation. Consulting revenues are recognized on a time and materials basis, or on a percentage of completion basis, depending on the contract, as employees and subcontractors provide services. Re venue from time and materials service contracts are recognized as the services are provided. Revenue from long term contacts is recognized based on actual hours incurred as specific deliverables are achieved consistent with the Company’s proportional performance under the contractual arrangement. Losses on contracts are recognized during the period in which the loss first becomes probable and reasonably estimable. Contract losses are determined to be the amount by which the estimated direct and indirect costs of the contract exceed the estimated total revenues that will be generated by the contract. Revenue recognized in excess of billings is recorded as unbilled services. Billings in excess of revenue recognized are recorded as deferred revenue until the above revenue recognition criteria are met. Reimbursements, including those relating to travel and other out-of-pocket expenses, and other similar third-party costs, are included in revenues.

Revenue from software license agreements is recognized upon execution of a license agreement and the shipment of the software, as long as all vendor obligations have been satisfied, the license fee is fixed and determinable and collection of the license fees is probable. Revenue from the sale of additional software products is recognized as software is delivered.

For all sales, we use a binding contract, purchase order or another form of documented agreement as evidence of an arrangement with the customer. Revenues from software license agreements are recognized upon receipt of an executed license agreement and shipment of the software, if there are no significant remaining vendor obligations, collection of the receivable is probable and payment is due in accordance with our normal payment terms.

We consider delivery to occur when we ship the product, so long as title and risk of loss have passed to the customer, as the customer has the right to use the product from that date.

At the time of a transaction, we assess whether the sale amount is fixed or determinable and whether collection is probable. If we determine the fee is not fixed or determinable, we recognize revenue when payment becomes due. We assess collectibility based on a number of factors, including the creditworthiness of the customer. If we determine that collectibility is not probable, we do not record revenue until such time when collectibility becomes probable, which is generally upon the receipt of cash.

Revenue earned on software arrangements involving multiple elements (i.e., software products, upgrades/enhancements, post contract customer support, installation, training, et cetera) is allocated to each element based on vendor specific objective evidence of relative fair value of the elements. When arrangements contain multiple elements and vendor specific objective evidence (“VSOE”) of fair value exists only for all undelivered elements, we recognize revenue for the delivered elements using the residual method. VSOE of fair value for each element is either the price charged when the same element is sold separately or the price established by management, having the relevant authority to do so, for an element not yet sold separately. For arrangements containing multiple elements wherein VSOE of fair value does not exist for all undelivered elements, revenue for the delivered and undelivered elements is deferred until VSOE of fair value exists or all elements have been delivered. The revenue allocated to post contract customer support is recognized ratably over the term of the support and revenue allocated to service elements (such as training and installation) is recognized as the services are performed.

Maintenance service revenue, whether sold separately or as part of a multiple element arrangement, is deferred and recognized ratably over the term of the maintenance contract, generally twelve months. Revenue allocated to professional service elements is recognized as the services are performed.

Due to the complexity of some software license agreements, we routinely apply judgment to the application of software revenue recognition accounting principles to specific agreements and transactions. Different judgments and/or different contract structures could have led to different accounting conclusions, which could have had a material effect on our reported quarterly earnings.

Capital Assets

We record our capital assets at their cost less accumulated depreciation. On a periodic basis, management reviews the carrying values of these assets and compares it to their estimated net recoverable amount. The determination of net recoverable amount necessitates various assumptions, many of which are forward looking and which are based on management’s best estimate of future revenues, expenses and cash flows. To the extent that actual financial performance adversely differs from the results projected by these assumptions, an impairment charge in the value of these assets would be necessary.

Goodwill and Other Intangible Assets

Goodwill is the residual amount that results when the purchase price of an acquired business exceeds the sum of the amounts allocated to the tangible and intangible assets acquired, less liabilities assumed, based on their fair values. When we enter into a business combination, the purchase method of accounting is used. Goodwill is assigned as of date of the business combination to reporting units that are expected to benefit from the business combination. Goodwill is not amortized but instead is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test is carried out in two steps. In the first step, the carrying amount of the reporting unit, including goodwill is compared with its fair value. When the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered to be impaired and the sec ond step of the impairment test is unnecessary. The second step is carried out when the carrying amount of reporting unit exceeds its fair value, in which case, the implied fair value of the reporting unit’s goodwill, determined in the same manner as the value of goodwill is determined in a business combination, is compares with its carrying amount to measure the amount of the impairment loss, if any.

During the third quarter of 2005, a Caradas customer contract expired and accordingly a goodwill and customer asset impairment analysis was performed for the Caradas reporting unit. The impairment analysis indicated that the fair values of goodwill and customer assets were nil, and the Company recorded a goodwill write down of $1,894,690 and a customer assets write down of $330,768. The impairment analysis for DSS indicated that the fair value of goodwill was nil and accordingly we recorded an impairment charge of $392,242 (included in loss from discontinued operations). Application of the goodwill impairment test requires judgment, including assignment of assets and liabilities and determination of the fair value of each reporting unit. The fair value of each reporting unit is estimated using a discounted cash flow methodology. This requires significant judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, the useful life over which cash flows will occur, and determination of discount rate and terminal asset value. The Company believes goodwill is recorded at its fair value as at December 31, 2005.

During fiscal 2004, Caradas was unable to attract significant new customers in order to generate expected cash flows, and DSS lost key management which resulted in the loss of several customers over the course of the year. The Company completed a goodwill impairment test as at December 31, 2004 and determined that goodwill of $2,500,000 relating to Caradas and $525,000 relating to DSS was impaired under the fair value methodology as prescribed under GAAP. Goodwill impairment charges for DSS have been included in the results from discontinued operations for all periods presented.

Recent Accounting Developments

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections” (“SFAS 154”), which replaces Accounting Principles Board Opinion No. 20, “Accounting Changes”, and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements”. SFAS 154 provides guidance on the accounting for and reporting of changes in accounting principles and error corrections. SFAS 154 requires retrospective application to prior period’s financial statements of voluntary changes in accounting principle and changes required by new accounting standards when the standard does not include specific transition provisions, unless it is impracticable to do so. Certain disclosures are also required for restatements due to correction of an error. SFAS 154 is effective for accounting changes and corrections of errors, made in fiscal years beginning after December 15, 2005. The impact that the adoption of SFAS 154 will hav e on the Company’s results of operations and financial condition will depend on the nature of future accounting changes and the nature of transitional guidance provided in future accounting pronouncements.

Liquidity and Capital Resources

Unaudited quarter ended December 31, 2005 compared to the unaudited quarter ended December 31, 2004

The net change in cash and cash equivalents and short term investments for the fourth quarter of 2005 was ($1,214,000) compared to $1,901,000 for the fourth quarter of 2004. The Q4 2005 decrease is mainly due to the continuing operating activities which used cash in an amount of $1,191,000. The Q4 2004 net change in cash and cash equivalents and short term investments of $1,901,000 is due to continuing operating activities, which used cash in an amount of $747,000 which was offset by the financing completed during December 2004 year for gross proceeds of $2,650,000.

Year ended December 31, 2005 compared to year ended December 31, 2004

Cash and cash equivalents at December 31, 2005 were $1,356,000 compared with $723,000 at December 31, 2004. Short term investments, being corporate debt securities with a term of less than 90 days that could be converted into cash, at December 31, 2005 were nil compared to $2,000,000 at December 31, 2004. The net change in cash and cash equivalents and short term investments for 2005 was ($1,368,000) compared to $932,000 for 2004. The fiscal 2005 decrease is mainly due to operating activities which used cash in an amount of $3,291,000 (compared to 2004 when operating activities used cash in the amount of $3,637,000) which was offset by a financing completed during 2005 for gross proceeds of $2,000,000 (in 2004 we completed two financing for gross proceeds of $2,000,000 in January 2004 and gross proceeds of $2,650,000 in December 2004).

On September 26, 2005, we completed a private placement of 5,000,000 common shares for gross proceeds of $2,000,000 and issued 71,250 common share purchase warrants to our placement agent. Each warrant entitles the holder to acquire one common share at a price of $0.40 per common share for a period of three years from September 26, 2005. During 2005 the Board approved an incentive plan, based on achievement of certain milestones, for the entire management team and employees consisting of up to $2,000,000 in cash and 2,000,000 nominal value warrants.

On January 20, 2004, we completed a private placement of 1,000,000 common shares and 1,100,000 common share purchase warrants for gross proceeds of $2,000,000. All the warrants expire on January 15, 2007 with 500,000 vesting immediately and exercisable at $2.00 per share, 350,000 vesting on January 15, 2005 and exercisable at a price of $2.05 and the remaining 250,000 warrants vesting on July 15, 2004 and exercisable at a price of $2.05 per share. The later two vestings will become immediate if any one of a number of significant changes occurs within us. During December 2004, we repriced the 350,000 warrants vesting on January 15, 2005 to $0.60 as part of a revised agreement for 2005 services.

On December 20, 2004, we completed a private placement of 6,925,000 common shares and 300,000 common share purchase warrants for gross proceeds of $2,650,000. Each warrant entitles the holder thereof to acquire one common share at a price of $0.40 per common share for a period of up to three years from December 20, 2004.

As of December 31, 2005, we had commitments under non-cancelable operating leases for our facilities and equipment through 2006 in amounts of $380,000 for fiscal 2006.

We are not subject to material market risk exposures, except for risks related to interest rate fluctuations and foreign currency exchange rates. Our exposure to market rate risk for changes in interest rates relates primarily to our cash equivalents and short term investments, created by our past financings. We have not used derivative financial instruments in our short term investments. We invest in high quality money market instruments and bonds with terms of less than 90 days. We are averse to principal loss and ensure the safety and preservation of our invested funds by limiting default, market and reinvestment risk. We do not make use of a bank line of credit and do not have any long-term debt. The impact of inflation has not been material to our business over the past five years.

We believe that our cash and cash equivalents as at December 31, 2005 of $1,356,000 may be insufficient to meet our short-term working capital requirements for the next fiscal year. We may need to raise additional amounts to meet our working capital requirements through private or public financings, strategic relationships or other arrangements. However, additional funding may not be available on terms attractive to us, or at all. If we enter into strategic relationships to raise additional funds, we may be required to relinquish rights to certain of our technologies. Our failure to either raise capital when needed or to generate revenues would leave us with insufficient resources to continue our business.

The following table presents unaudited selected financial data for each of the last eight quarters ending December 31, 2005:

	Revenue for the period	Loss from continuing operations	Loss (income) from discontinued operations	Loss for the period	Loss per share from continuing operations	Loss per share
	($000’s)	($000’s)	($000’s)	($000’s)	($)	($)
December 31, 2005	159	1,057	28	1,030	0.04	0.04

March 31, 2004	853	1,228	115	1,343	0.10	0.11

The September 30, 2005 quarterly loss is higher than previous quarters largely due to the inclusion of a goodwill impairment change of $1,895,000 and a customer asset impairment charge of $331,000. The December 31, 2004 quarterly loss is higher than previous quarters largely due to the inclusion of a goodwill impairment charge of $2,500,000 and $145,000 of depreciation and amortization charge relating to the joint venture.

Year ended December 31, 2004 compared to year ended December 31, 2003

Cash and cash equivalents at December 31, 2004 were $723,000 compared with $548,000 at December 31, 2003. Short term investments, being marketable bonds with a term of less than 90 days that could be converted into cash, at December 31, 2004 were $2,000,000 compared to $1,244,000 at December 31, 2003. The net change in cash and cash equivalents and short term investments for 2004 was $932,000 compared to $318,000 for 2003. The fiscal 2004 increase is mainly due to operating activities which used cash in an amount of $3,637,000 (compared to 2003 when operating activities used cash in the amount of $2,264,000) which was offset by two financing completed during 2004, $2,000,000 gross proceeds in January 2004 and $2,650,000 gross proceeds in December 2004 (compared to $3,100,000 gross proceeds in June 2003) and the repayment of $50,000 of promissory notes payable. Included in the 2004 operating activities was $225,000 paid to settle a leg al fee dispute with our former attorneys on the Silva Run litigation.

The fiscal 2003 net change in cash and cash equivalents and short term investments of $317,000 was due to operating activities, which used cash in an amount of $984,000, the investment to acquire DSS and Caradas for net $541,000, the repayment of DSS’ bank indebtedness of $240,000 and the repayment of notes payable related to the acquisition of DSS of $873,000. These cash usages were offset by financings of net $2,921,000 (being the June 2003 financing for gross proceeds of $3,100,000 net of fees).

On June 23, 2003, we completed a private placement of 5,000,000 common shares at a price of $0.62 per common share for gross proceeds of $3,100,000. The placement agent exercised its option to receive 500,000 common shares in lieu of its $310,000 fee from this private placement. The placement agent also received 40,000 common shares in lieu of its $24,000 retainer fee to act as placement agent. Further compensation was issued as a three-year broker cashless exercisable warrant terminating on June 20, 2006 to purchase up to 500,000 common shares at $0.62 per share. The placement agent has exercised 440,000 in a cashless exercise to receive 304,037 common shares.

As of December 31, 2004, we had commitments under non-cancelable operating leases for our facilities and equipment through 2006 in amounts ranging from $528,000 in fiscal 2005 declining to $380,000 in fiscal 2006.

The net change in cash and cash equivalents and short term investments for the fourth quarter of 2004 was $1,762,000 compared to ($488,000) for the fourth quarter of 2003. The increase is mainly due to the fourth quarter of 2004 operating activities which used cash in an amount of $861,000 which was offset by the financing completed during December 2004 year for gross proceeds of $2,650,000.

The fourth quarter 2003 net change in cash and cash equivalents and short term investments of ($488,000) was due to operating activities, which used cash in an amount of $757,000 offset by the increase in promissory notes and notes payable related to the acquisition of Caradas of $162,000 and the issuance of shares for services to investment bankers and warrant compensation expense for $161,000.

With the acquisition of Caradas in September 2003, we acquired an opening accounts receivable balance of $985,000. This opening balances and collections thereafter, helped contribute to the $571,000 change in accounts receivable during the fourth quarter of 2003.

Research and Development, Patents and Licenses, et cetera

We plan to continue to invest in research and development for our mobile device security products based on the technology we purchased in 1996, and we anticipate spending approximately $1,650,000 in the year ending December 31, 2006 in connection with these efforts. We expect to allocate funds almost entirely to salary payments to staff for the continued research and development of our security product suite. We cannot reasonably estimate when the benefits, if any, of the continued development costs will be realized. We also cannot reasonably estimate whether any of the continuing development costs will result in revenue for us, or whether additional sources of funding will be available if continued development of the technology is unsuccessful.

5-D.

Trend Information

At this time, we cannot identify any known trends that are reasonably likely to have a material effect on our business due to a number of factors. We currently have several customers that are using our products for pilot projects. The sales cycle can take a significant amount of time. In addition to customer constraints, such as budgetary restrictions, the integration process required to make our products function properly within a customer’s specific application may be complex. Mobile data commerce applications are also in their infancy, and the need for security applications is dependent on the adoption of these applications by consumers.

Our revenue model consists of (i) license fees from the licensing of our product suite which are one-time fees typically recorded upon execution of the license agreement, (ii) consulting revenues, as employees and subcontractors provide services to our customers, which are recognized on a time and materials basis, or on a percentage of completion basis, depending on the contract, as employees and subcontractors provide services (iii) recurring royalties from the provision of certificates and permits, and (iv) annual support fees. As our business evolves, we expect that most of our revenue will be generated through recurring royalties. This revenue stream is dependent on the adoption of transaction-based applications over wireless networks and therefore cannot be accurately projected at this time.

We are not aware of any other trends, uncertainties, demands, commitments or events which are reasonably likely to have a material effect upon our net sales or revenues, income from continuing operations, profitability, liquidity or capital resources.

Off-balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have had, or are reasonably likely to have, a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Compensation of Directors

Our directors received no compensation during fiscal 2005 for attending meetings of the board of directors or a committee of the board of directors.

Prior to February 2005, it had been our practice to grant to a director 50,000 options to acquire common shares of the Corporation upon his or her election as a director. In addition we may grant directors additional options from time to time. During fiscal 2005, Messrs Beck (who resigned in December 2004) Powell, Steinman, and Shiu each received 30,000 common shares. During fiscal 2005, Messrs Beck, Steinman, and Shiu each received 30,000 common share purchase options at $0.40 and Powell received 30,000 options at $0.40 and 30,000 at $0.63. Such options are exercisable to acquire common shares at the market price on the day preceding the grant pursuant to the terms of our Amended and Restated Stock Option Plan. Furthermore, during February 2005, our Compensation Committee proposed and the full Board of Directors approved a change to director compensation. For 2005 onward, each non-management directors shall receive either (i) 30,000 Diversinet common shares, or (ii) Cdn$10,000 (2,500 quarterly in arrears) and 30,000 options.

Options to Purchase Our Securities

Our Amended and Restated Stock Option Plan was established on October 15, 1993 and was amended on February 4, 1997, April 16, 1999, May 15, 2000, January 22, 2003, August 15, 2003, February 22, 2005 and February 22, 2006. Under our share option plan, options for up to a specified maximum limit of 3,900,000 common shares may be granted from time to time by the board of directors to our directors, officers, employees and consultants of us and any of our subsidiaries. Options granted under our share option plan have an exercise price equal to the closing price of the common shares on the day immediately proceeding the day of the grant and generally will be exercisable over a two-year period and will expire after five years.

The share option plan provides that:

(i)

The maximum number of common shares which may be reserved for issuance to any participant pursuant to share options may not exceed 5% of the common shares outstanding at the time of grant (on a non-diluted basis) less the aggregate number of common shares reserved for issuance to such person under any other option to purchase common shares from treasury granted as a compensation or incentive mechanism;

(ii)

The maximum number of common shares that may be issued to any one insider and his associates within a one year period may not exceed 5% of the outstanding issue;

(iii)

The maximum number of common shares that may be reserved for issuance to Diversinet insiders is limited to 10% of the common shares of the outstanding issue at the time of the grant (on a non-diluted basis) less the aggregate number of common shares reserved for issuance to insiders under any other share compensation arrangement; and

(iv)

The maximum number of common shares that may be issued to our insiders within a one-year period may not exceed 10% of the outstanding issue.

As at February 28, 2006, there were a total of 2,261,123 options to purchase common shares outstanding under our share option plan at exercise prices ranging from $0.37 to $15.30 with expiration dates ranging from April 1, 2006 to January 23, 2011. The directors and officers as a group hold options to purchase 1,515,000 of our common shares.

Board Practices

Our Board presently consists of five directors who are elected annually. Each director elected will hold office until the close of business of our first annual meeting of shareholders following his election unless his office is earlier vacated in accordance with our by-laws. During 2005 we had three director resignations, Stanley Beck, Charles Shiu and Charles Walton. During fiscal 2004 we had two director resignations, Derek Buntain and Albert Wahbe. James B. Wigdale was appointed on January 3, 2005 to replace one of the directors. Brian Barry was appointed on March 11, 2005 to replace one of the directors. The Board has established three committees: the Audit Committee, the Compensation Committee and the Governance Committee. Committee members are appointed annually following our annual meeting of shareholders.

Audit Committee

The Audit Committee is comprised of three non-management directors. The Audit Committee has adopted a formal charter that details its mandate.

The Audit Committee has also established procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters and the confidential, anonymous submission by employees of complaints or concerns regarding questionable accounting or auditing matters. Any employee of ours or our affiliates may submit a good faith complaint regarding accounting or auditing matters to our management without fear of dismissal or retaliation of any kind.

The Audit Committee assists the Board in its oversight functions as they relate to the accounting, financial reporting, auditing, risk management and internal controls. The Audit Committee has the following duties and responsibilities: (a) reviewing our audited financial statements and our unaudited interim financial statements and recommending whether such statements should be approved by the Board; (b) reviewing management’s discussion and analysis of financial condition and results of operations and related press releases and recommending whether such documents should be approved by the Board; (c) recommending to the Board the firm of independent auditors to be nominated for appointment by shareholders at each annual general meeting and, where necessary, the removal of the independent auditors; (d) reviewing the scope and adequacy of audits to be conducted by the independent auditors; (e) adopting and annually reassessing formal terms of refere nce for the independent auditors; (f) monitoring and evaluating the independence and performance of the independent auditors; (g) pre-approving all non-audit services to be provided to us by our independent auditors prior to the commencement of such services; (h) reviewing all post-audit management letters containing the recommendations of the independent auditors and response or follow-up thereto from management; (i) reviewing and monitoring the integrity, adequacy and timeliness of the financial reporting and disclosure practices; (j) monitoring our compliance with legal and regulatory requirements related to financial reporting and disclosure; (k) monitoring and evaluating the adequacy of the internal accounting and audit procedures; (l) reviewing and ensuring the acceptability of our accounting principles; (m) identifying the principal financial risks; (n) overseeing reporting on internal controls of management and ensuring that management has designed and implemented an effective system of internal cont rols; (o) reviewing, and if deemed advisable, approving all related party transactions as defined in the governing legislation; (p) annually reviewing and reassessing the adequacy of the duties and responsibilities of the Audit Committee; and (q) any other matters that the Audit Committee feels are important to its mandate or that the Board chooses to delegate to it.

It is the responsibility of the Audit Committee to maintain an open avenue of communication between itself, our independent outside auditor and our management. In performing its role, the Audit Committee is empowered to investigate any matter brought to its intention, with full access to all our books, records, accounts, facilities and personnel. The Audit Committee is also empowered to instruct and retain outside counsel or other experts as necessary.

The members of the Audit Committee are Mark Steinman (Chair), Keith Powell and James Wigdale, all of whom are non-management directors. To carry out its responsibilities, the Audit Committee held four meetings during the year ended December 31, 2005 and four meetings during the year ended December 31, 2004.

Compensation Committee

Overview and Philosophy

The Compensation Committee is comprised of two directors. It is the responsibility of the Compensation Committee to determine the level of compensation and to develop recommendations for stock option grants for approval by the Board of Directors in respect of our senior executives with a view to providing such executives with a competitive compensation package having regard to performance. Performance is defined to include achievement of our strategic objective of growth, development of the business, enhancement of shareholder value and attainment of annual goals as set by the Board of Directors. The members of the Compensation Committee are Keith Powell (Chair) and Jay Wigdale.

Published industry salary data is reviewed and relied upon in the Compensation Committee’s assessment of appropriate compensation levels, specifically the analysis of proxies of certain public software companies and appropriate and relevant compensation surveys.

The Compensation Committee recognizes that the industry sector in which we operate is both highly competitive and undergoing significant globalization with the result that there is substantial demand for qualified, experienced executive personnel. The Compensation Committee considers it crucial that we are assured of retaining and rewarding its top caliber executives who are essential to the attainment of our ambitious long-term, strategic goals.

For these reasons, the Compensation Committee believes our executive compensation arrangements must remain competitive with those offered by other companies of similar size, scope, performance levels and complexity of operations, including some, but not all, of the companies comprising the Nasdaq Stock Market, the Over the Counter Bulletin Board and the Toronto Venture Exchange.

Annual Cash Compensation (Base Salary Plus Performance Incentives)

The Compensation Committee believes that annual cash compensation should be paid commensurate with attained performance. The executive cash compensation consists of base compensation and performance incentives. Base salaries for executive officers are established by considering a number of factors, including our operating results; the executive’s individual performance and measurable contribution to our success; and pay levels of similar positions with comparable companies in the industry. The Compensation Committee believes that our executive compensation must remain competitive for us to retain talented executives. Base salaries are typically reviewed annually.

The purpose of annual performance incentive compensation is to provide cash compensation that is at-risk on an annual basis and is contingent on the achievement of annual business and operating objectives. Annual incentives measure business performance and individual performance, and are designed to provide a pay-out scale with high upside opportunity for high performance and zero pay out for low performance. The Compensation Committee sets targets for executive bonuses each year and the pay out of those bonuses, if any, is determined based on our operating results, the executive’s measurable contribution to our success, and bonus levels of similar positions with comparable companies in the industry.

For the year ending December 31, 2005, the Compensation Committee recommended and approved a total of $25,000 for the executive team out of a potential total bonus pool of $630,000 or 4% of the potential total bonus pool. The low percentage pay out of executive bonuses reflects the view of both management and the Compensation Committee that executive bonuses should be based on the factors described above. There are currently no guaranteed executive bonuses for 2005 or beyond.

Stock Options

The Committee recommends executive stock options under the Diversinet Corp. Amended and Restated Stock Option Plan to foster executive officer ownership of our common stock, to stimulate a long-term orientation in decisions and to provide direct linkage with stockholder interests. The Compensation Committee considers the total compensation package, industry practices and trends, the executive’s accountability level, and assumed potential stock value in the future when granting stock options. The Compensation Committee recommends option amounts to provide retention considering projected earnings to be derived from option gains based upon relatively conservative assumptions relating to planned growth and earnings. Therefore, the stock option program is intended to serve as an effective and competitive long-term incentive and retention tool for our executives, as well as other key employees. The exercise prices of stock options gran ted to executive officers are equal to the fair market value of our common stock on the date of grant. Therefore, stock options provide an incentive to maximize our profitable growth that ordinarily, over time, should be reflected in the price of our common stock.

Benefits

We provide benefits to the named executive officers that are generally available to all our employees.

Chief Executive Officer Compensation

The Chief Executive Officer’s compensation is paid in accordance with the terms of his employment contract which provides for payment of an annual base salary of Cdn$220,000 and an annual performance bonus of up to Cdn$250,000. In addition, Mr. Moustafa participates in the Amended and Restated Stock Option Plan.

The Compensation Committee did not directly base Mr. Moustafa’s bonus and option grants on rates for comparable employers, although the Compensation Committee did consider the compensation of CEOs of other issuers in the same industry in determining Mr. Moustafa’s overall compensation. In addition, Mr. Moustafa is entitled to participate in our bonus plan and stock option awards as part of his compensation. In the financial year ended December 31, 2005, Mr. Moustafa was granted zero options to purchase Common Shares. The historical stock option awards to Mr. Moustafa are consistent with our compensation philosophy, which is to tie a portion of the Chief Executive Officer’s compensation to corporate performance and the achievement of growth in shareholder value.

Governance Committee

The Governance Committee is comprised of two non-management director. The Governance Committee assists the Board of Directors in fulfilling its oversight responsibilities related to seeking candidates for membership on the Board of Directors, assessing the corporate governance policies and processes of the Board of Directors and reviewing from time to time the policies of the Board of Directors related to director qualifications, compensation, tenure and retirement. The members of the Governance Committee are Keith Powell (Chair) and Brian Barry.

This note was payable in installments of $300,000 on January 2, 2004 and $300,000 on January 2, 2005 and bears no interest.

In February 2004, we amended the DSS Software Technologies share purchase agreement.

Consolidated Statements and Other Financial Information

The financial statements are included in this Registration Statement, Form 20-F under Item 17.

Legal proceedings

There is currently one material claim pending against us. If we lose this suit or enter into settlement requiring us to pay cash or to issue any of our common shares, our liquidity and financial position will be adversely affected and our shareholders’ ownership may be diluted.

Instant Publisher (Israel) Litigation Matter

In May 2000, we were sued in the Ontario Superior Court of Justice, along with our wholly-owned Barbados subsidiary, The Instant Publisher Ltd., by Instant Publisher (Israel) Limited, a company not related to us. Instant Publisher (Israel) Limited is seeking damages of $1,533,950 for breach of an October 25, 1995 dealer agreement with our previous printing business regarding the distribution of printing equipment, and damages of $25,000,000 for loss of reputation and loss of opportunity, pre-judgment and post-judgment interest, and costs. Based on our preliminary evaluation of the merits of this claim, we filed a notice of intention to defend against the claim. If we are required to pay damages, this could have a material adverse effect on our liquidity and our ability to fund our business.

In addition to the above, in the ordinary course of business, we and our subsidiaries have legal proceedings brought against us.

8-B. Significant Changes

During February 2005, one of our subsidiaries (DSS) entered into an Asset Purchase Agreement to sell the majority of its assets and liabilities to a third party. The effect of this will be that we will discontinue providing services to DSS’ customers. During 2005, the revenues associated with DSS were $453,000.

During February 2006, Kashif Hassan resigned as President. Mr. Hassan’s role has been filled by the current senior management team. Mr. Hassan’s departure did not result from any disagreement with the Company. When Mr. Hassan joined the team in early 2005 as President, his focus was to restructure the organization around our mobile mass market authentication solutions. With the achievement of these turnaround milestones accomplished, Kash has completed his objectives.

During February 2006, RSA Security Inc. entered into a license agreement under which Diversinet will provide mobile device and PC-based software tokens and integrated provisioning services. The agreement includes licensing, development and revenue-sharing components that will result in revenues of a minimum of $2.2 million to Diversinet over three years. Under this commercial agreement, the Diversinet MobiSecure soft token suite and Diversinet’s MobiSecure Authentication Service Center (MASC) will be integrated into RSA Security’s products and services, enabling the downloading, provisioning, and management of RSA Security’s mobile and PC-based soft tokens.

Except as noted above, no significant change has occurred since the date of the audited financial statements included in this Annual Report on Form 20-F.

In effect, theICA requires review by Investment Canada, the agency which administers theICA, and approval by the Canadian government in the case of an acquisition of control of a Canadian business by a non-Canadian that is a WTO Investor (as defined in theICA) where: (i) in the case of a direct acquisition of control of a Canadian entity (i.e., through a share purchase), the assets of the entity carrying on the Canadian Business and of all other entities in Canada, the control of which is acquired exceeds$184 million (this threshold is adjusted annually for inflation and growth in Canada’s domestic product); or (ii) in the case of a direct acquisition of assets of a Canadian Business (i.e., through an asset acquisition) the value of the assets used in carrying on the Canadian business exceeds$184 million. Indirect acquisitions (for example, the acquisition of the foreign parent of the Canadian business) of assets or indirect acquisitions of control by a WTO investor are not reviewable, but are still notifiable. Where an investor is not a WTO Investor, review is required where: (i) in the case of a direct acquisition of control of a Canadian Business, the value of the assets of the business and all other entities being acquired is$5 million or more; or (ii) in the case of an indirect acquisition of control of a Canadian Business, where the Canadian Business has assets of$50 million or more in value; or (iii) in the case of an acquisition of assets of a Ca nadian Business, the assets represents more than 50% of the assets of the original group and the value of the acquired assets exceeds$5 million. These lower thresholds also apply, even where the investor is a WTO investor, where the Canadian Business is engaged in certain activities relating to “Canada’s cultural heritage or national identity” such as book publishing, film production and distribution, television and radio, production and distribution of music, uranium production, certain financial services or transportation services.

In the context of Diversinet, in essence, three methods of acquiring control of a Canadian business are regulated by theICA: (i) the acquisition of all or substantially all of the assets used in carrying on the Canadian business; (ii) the acquisition, directly or indirectly, of voting shares of a Canadian corporation carrying on the Canadian business; (iii) the acquisition of voting shares of an entity which controls, directly or indirectly, another entity carrying on a Canadian business. An acquisition of a majority of the voting interests of an entity, including a corporation, is deemed to be an acquisition of control in accordance with theICA. An acquisition of less than one-third of the voting shares of a corporation is deemed not to be an acquisition of control. An acquisition of less than a majority, but one-third or more, of the voting shares of a corporation is presumed to be an acquisition of contro l unless it can be established that on the acquisition the corporation is not, in fact, controlled by the acquirer through the ownership of voting shares. For partnerships, trusts joint ventures or other unincorporated entities, an acquisition of less than a majority of the voting interests is deemed not to be an acquisition of control.

If an acquisition of control of a Canadian business by a non-Canadian is not reviewable, theICA requires a formal notification to the Canadian government. These provisions require a foreign investor to give notice in the required form, which notices are for information, as opposed to review, purposes.

10-E. Taxation

Certain Canadian Federal Income Tax Consequences

The following summary of the material Canadian federal income tax considerations generally applicable in respect of the holding and disposition of common shares reflects our opinion as of the date hereof. The tax consequences to any particular holder of common shares will vary according to the status of that holder as an individual, trust, corporation or member of a partnership, the jurisdiction in which that holder is subject to taxation, the place where that holder is resident and, generally, according to that holder’s particular circumstances.

This summary is applicable only to holders who are resident solely in the United States, have never been resident in Canada, deal at arm’s length with us, hold their common shares as capital property and who will not use or hold the common shares in carrying on business in Canada.

This summary is based upon the provisions of theIncome Tax Act (Canada) and the regulations thereunder (collectively, the “Tax Act” or “ITA”) and the Canada-United States Tax Convention (the “Tax Convention”) as at the date hereof and the current administrative practices of the Canada Customs and Revenue Agency. This summary does not take into account provincial income tax consequences.

This summary is not exhaustive of all possible income tax consequences. It is not intended as legal or tax advice to any particular holder of common shares and should not be so construed. Each holder should consult his own tax advisor with respect to the income tax consequences applicable to him in his own particular circumstances.

Dividends

In the case of any dividends paid to non-resident shareholders, we withhold the Canadian tax, which remits only the net amount to the shareholder. The rate of withholding tax is generally 25% but by virtue of Article X of the Tax Convention, the rate of tax on dividends paid to persons who are residents only of the United States for purposes of the Tax Convention is generally limited to 15% of the gross amount of the dividend (or 5% in the case of certain corporate shareholders owning at least 10% of our voting shares).

Dispositions

A non-resident of Canada is not subject to tax under theITA in respect of a capital gain realized upon the disposition of a common share unless the share is “taxable Canadian property” to the holder thereof and the non-resident is not entitled to relief under a tax treaty. In the case of a non-resident holder to whom our common shares are taxable Canadian property and who is resident only in the United States for purposes of the Tax Convention, no tax under theITA will be payable on a capital gain realized on such shares by reason of the Tax Convention unless the value of such shares is derived principally from real property situated in Canada. We believe that the value of our common shares is not derived from real property situated in Canada.

Our common shares will be taxable Canadian property to a non-resident holder if, at any time during the period of sixty months immediately preceding the disposition, the non-resident holder, persons with whom the non-resident holder did not deal at arm’s length, or the non-resident holder together with persons with whom the holder did not deal at arm’s length owned 25% or more of our issued shares of any class or series. Holders to whom our common shares are taxable Canadian property and who are not entitled to relief under the Tax Convention should consult their own tax advisors in advance of any disposition of common shares.

United States Federal Income Tax Consequences

The following is a discussion of material United States Federal income tax consequences generally applicable to a U.S. Holder (as defined below) of our common shares. This discussion does not address all potentially relevant Federal income tax matters, and it does not address consequences peculiar to persons subject to special provisions of Federal income tax law, such as, for example, tax-exempt organizations, qualified retirement plans, persons subject to alternative minimum tax, financial institutions, insurance companies, real estate investment trusts, regulated investment companies, broker-dealers, non-resident alien individuals or foreign corporations whose ownership of our common shares is not effectively connected with the conduct of a trade or business in the United States and shareholders who acquired their shares through the exercise of employee share options or otherwise as compensation. In addition, this discus sion only applies to common shares held by U.S. Holders as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, and does not cover any state, local or foreign tax consequences.

The following discussion is based upon the sections of the Internal Revenue Code, Treasury Regulations, published Internal Revenue Service rulings, published administrative positions of the Internal Revenue Service and court decisions that are currently applicable, any or all of which could be materially and adversely changed, possibly on a retroactive basis, at any time. The following discussion is for general information only and is not intended to be, nor should it be construed to be, legal or tax advice to any holder or prospective holder of our common shares and no opinion or representation with respect to the United States Federal income tax consequences to any such holder or prospective holder is made. Accordingly, holders and prospective holders of our common shares should consult their own tax advisors about the federal, state, local, and foreign tax consequences of purchasing, owning and disposing of our common shares.

U.S. Holders

As used herein, a “U.S. Holder” includes any person, with the exception of those subject to special provisions of Federal income tax law, who holds our common shares who is a citizen or resident of the United States, a partnership or corporation organized under the laws of the United States, an estate, the income of which is subject to United States federal income tax without regard to its source and a trust if a United States court is able to exercise primary supervision over administration of the trust and one or more United States persons have authority to control all substantial decisions of the trust or if the trust was in existence on August 20, 1996 and has elected to continue to be treated as a United States person, and any other person or entity whose ownership of our common shares is effectively connected with the conduct of a trade or business in the United States.

Distributions on Our Common Shares

U.S. Holders receiving dividend distributions (including constructive dividends) with respect to our common shares are required to include in gross income for United States Federal income tax purposes the gross amount of such distributions to the extent that we have current or accumulated earnings and profits, without reduction for any Canadian income tax withheld from such distributions. Such Canadian tax withheld may be credited, subject to certain limitations, against the U.S. Holder’s United States Federal Income tax liability or, alternatively, may be deducted in computing the U.S. Holder’s United States Federal taxable income by those who itemize deductions (see more detailed discussion at “Foreign Tax Credit” below). To the extent that distributions exceed our current or accumulated earnings and profits, they will be treated first as a return of capital up to the U.S. Holder’s adjusted basis in the common shares and thereafter as gain from the sale or exchange of the common shares. Preferential tax rates for long-term capital gains are applicable to an U.S. Holder, which is an individual, estate or trust. There are currently no preferential tax rates for long-term capital gains for an U.S. Holder, which is a corporation. Dividends paid in Canadian dollars will be included in income in an U.S. dollar amount based on the exchange rate at the time of their receipt. U.S. Holders should consult their own tax advisors regarding the treatment of any foreign currency gain or loss on any Canadian dollars received as a dividend which are converted into U.S. dollars on a date subsequent to receipt.

Dividends paid on our common shares will not generally be eligible for the dividends received deduction provided to corporations receiving dividends from certain United States corporations. A U.S. Holder which is a corporation may, under certain circumstances, be entitled to a 70% deduction of the United States source portion of dividends received from us (unless we qualify as a “foreign personal holding company” or a “passive foreign investment company”, as defined below) if such U.S. Holder owns shares representing at least 10% of the voting power and value of Diversinet. The availability of this deduction is subject to several complex limitations, which are beyond the scope of this discussion.

Foreign Tax Credit

A U.S. Holder who pays (or has withheld from distributions) Canadian income tax with respect to the ownership of our common shares may be entitled, at the option of the U.S. Holder, to either a deduction or a tax credit for such foreign tax paid or withheld. Generally, it will be more advantageous to claim a credit because a credit reduces United States Federal income taxes on a dollar-for-dollar basis, while a deduction merely reduces the taxpayer’s income subject to tax. This election is made on an annual basis and applies to all foreign income taxes (or taxes in lieu of income tax) paid by (or withheld from) the U.S. Holder during the year. There are significant and complex limitations which apply to the credit, among which is the general limitation that the credit cannot exceed the proportionate share of the U.S. Holder United States income tax liability that the U.S. Holder’s foreign source income bears to his/her or its worldwide taxable income.

In the determination of the application of this limitation, the various items of income and deduction must be classified into foreign and domestic sources. Complex rules govern this classification process. There are further limitations on the foreign tax credit for certain types of income such as “passive income”, “high withholding tax interest”, “financial services income”, “shipping income”, and certain other classifications of income. In certain circumstances, recently enacted legislation and other guidance issued by the United States Treasury may deny a United States holder foreign tax credits (and instead may allow deductions) for foreign taxes imposed on a dividend if the United States holder (i) has not held the common shares for at least 16 days in the 30-day period beginning 15 days before the ex-dividend date, during which it is not protected from risk of loss; (ii) is obligated t o make payments related to the dividends; or (iii) holds the common shares in arrangements in which the United States holder’s expected economic profit, after non-U.S. taxes, is insubstantial.

The availability of the foreign tax credit and the application of the limitations on the credit are fact specific and holders and prospective holders of our common shares should consult their own tax advisors regarding their individual circumstances.

Disposition of Our Common Shares

A U.S. Holder will recognize gain or loss upon the sale of our common shares equal to the difference, if any, between (i) the amount of cash plus the fair market value of any property received, and (ii) the shareholder’s tax basis in the our common shares. Any gain recognized on the sale or other disposition of common shares will generally be U.S. source income. Any loss recognized on the sale or other disposition of common shares will generally be U.S. source. However, such loss will be foreign source to the extent certain dividends were received by the U.S. Holder within the 24-month period proceeding the date on which the loss was recognized. This gain or loss will be capital gain or loss if the common shares are capital asset in the hands of the U.S. Holder, which will be a short-term or long-term capital gain or loss depending upon the holding period of the U.S. Holder. Gains and losses are nette d and combined according to special rules in arriving at the overall capital gain or loss for a particular tax year. Deductions for net capital losses are subject to significant limitations. For U.S. Holders who are individuals, a capital loss is deductible only to the extent of capital gains, plus ordinary income of up to U.S. $3,000; any unused portion of such net capital loss may be carried over to be used in later tax years until such net capital loss is thereby exhausted. For U.S. Holders which are corporations (other than corporations subject to Subchapter S of the Internal Revenue Code), any unused net capital loss may be carried back three years from the loss year and carried forward five years from the loss year to be offset against capital gains until such net capital loss is thereby exhausted. If the amount realized on a sale or exchange is not denominated in U.S. dollars, the amount realized will be equal to the U.S. dollar value thereof, determined at the spot rate on the date of the sale or exchange.

Until such time as our common shares are listed on a stock exchange prescribed for the purposes of the Income Tax Act (Canada) (which includes NASDAQ, but not the OTC BB) our common shares will be taxable Canadian property for the purposes of the Income Tax Act (Canada).

Under section 116 of the Income Tax Act (Canada), non-resident vendors who dispose of certain types of taxable Canadian property (including our common shares for as long as they are not listed on a prescribed stock exchange), have to notify Canada Customs and Revenue Agency (CCRA) about the disposition either before they dispose of the property or after they dispose of it. This notification (the “Notice of Disposition”) is due not later than ten (10) days after the date the property was disposed of. The vendor may be able to claim an exemption under an applicable tax treaty at the time the Notice of Disposition is filed. If no exemption is available under an applicable treaty, before CCRA can issue a certificate of compliance to the vendor, CCRA must receive either an amount to cover the tax owing, or appropriate security for the tax on any gain the vendor may realize at the time the property is disposed of. Such payments or secur ity the vendor provides will be credited to the vendor’s account. If the vendor does not comply with the section 116 requirements, which the vendor must do so before receiving the certificate of compliance, the purchaser of the property may deduct or withhold a specified amount from the proceeds of the disposition to cover any tax which the vendor owes.

When filing a Notice of Disposition and claiming an exemption under a specific tax treaty, necessary documentation to support the claim should be submitted along with the request. The documentation which is acceptable must be based on the particular tax treaty under which the exemption is claimed, such as proof of residency, or that the gain has or will be reported in the vendor’s country. Tax officials, in some countries, will supply the necessary certification required to claim the exemption. The United States Department of the Treasury, Internal Revenue Service will provide certification for corporations, exempt organizations and individuals. Requests for certification should be sent to the appropriate service centre. The Department of the Treasury, Publication 686, Certification for Reduced Tax Rates in Tax Treaty Countries, outlines the certification process.

If the vendor does not obtain a certificate pursuant to section 116, the purchaser becomes liable to pay as tax, on behalf of the vendor, an amount equal to 25% of the proceeds of disposition. The purchaser of the property is then entitled to withhold that amount from the proceeds of the disposition to cover any tax which the vendor owes or may owe.

The required amount must be remitted to the Receiver General for Canada 30 days after the end of the month is which the property was acquired.

Other Considerations

In the following three circumstances, the above sections of the discussion may not describe the United States Federal income tax consequences resulting from the holding and disposition of our common shares. Based on (a) the number of shareholders of our common shares, and (b) the majority ownership of our shares by Canadian residents, we do not believe that we are either a “Foreign Personal Holding Company” or a “Controlled Foreign Corporation.” However, we do believe that we are likely to be treated as a “Passive Foreign Investment Company” for the taxable years 2003, 2004 and 2005.

Foreign Personal Holding Company

If, at any time during a taxable year, more than 50% of the total combined voting power or the total value of our outstanding shares are owned, actually or constructively, by five or fewer individuals who are citizens or residents of the United States and 60% or more of our gross income for such year was derived from certain passive sources (e.g. from dividends received from unrelated persons), we would be treated as a “foreign personal holding company.” In that event, U.S. Holders that hold our common shares would be required to include in gross income for such year their allowable portions of such foreign personal holding company income to the extent that we do not actually distribute such income.

Controlled Foreign Corporation

If more than 50% of the voting power of all classes of shares or the total value of our shares is owned, directly or indirectly, by U.S. shareholders, each of whom own 10% or more of our voting shares (“U.S. Shareholders”), we could be treated as a “controlled foreign corporation” (a “CFC”) under SubPart F of the Internal Revenue Code. If we were classified as a CFC and as a PFIC, CFC treatment would prevail with respect to U.S. Shareholders. CFC classification would effect many complex results including the required inclusion by such U. S. shareholders in income of their pro rata share: of “SubPart F Income” (as specially defined by the Internal Revenue Code) of Diversinet; and of our earnings invested in U.S. property. In addition, under Section 1248 of the Internal Revenue Code, gain from the sale or exchange of our common shares by a U.S. person who is or was a U.S. sharehol der (as defined in the Internal Revenue Code) at any time during the five years period ending with the sale or exchange is generally treated as ordinary dividend income to the extent of our earnings and profits attributable to the shares sold or exchanged. Because of the complexity of SubPart F, and because it is not clear that we are a controlled foreign corporation, a more detailed review of these rules is outside of the scope of this discussion.

Passive Foreign Investment Company

As stated above, we believe that we will not be treated as a passive foreign investment company (“PFIC”), as defined in Section 1297 of the Internal Revenue Code, for our fiscal years 2004 or 2005.

United States income tax legislation contains rules governing PFIC’s, that can have significant tax effects on U.S. Holders of foreign corporations. These rules do not apply to non-U.S. Holders. Section 1297 of the Internal Revenue Code defines a PFIC as a corporation that is not formed in the United States and, for any taxable year, either (i) 75% or more of its gross income is “passive income”, which includes interest, dividends and some types of rents and royalties or (ii) the average percentage, by fair market value (or, if the company is a controlled foreign corporation or makes an election, by adjusted tax basis), of its assets that produce or are held for the production of “passive income” is 50% or more. Based on these tests we do not meet the definition of a PFIC in 2000, 2001, 2002, 2003 or 2004.

An U.S. Holder who holds shares in a foreign corporation during any year in which such corporation qualifies as a PFIC is subject to U.S. Federal income taxation under alternative tax regimes, depending upon whether such U.S. Holder makes elections. The following is a discussion of these alternative tax regimes as applicable to our U.S. Holders.

A U.S. Holder of a PFIC who does not make either of the elections described below (a “Non-electing U.S. Holder”) is subject to special taxation rules under Section 1291 of the Internal Revenue Code with respect to (i) gains realized on the disposition (or deemed to be realized by reason of a pledge) of his/her common shares and (ii) excess distributions by us, defined as any distribution received by a U.S. Holder from a PFIC in a taxable year that is greater than 125% of the average distributions received by the U.S. Holder in the three preceding taxable years, or, if shorter, the U.S. Holder’s holding period for the shares.

A Non-electing U.S. Holder generally would be required to include in income pro rata all gains realized on the disposition of his/her common shares and all excess distributions over the entire holding period for the PFIC common shares. All gains or excess distributions allocated to prior years of the U.S. Holder (other than years prior to the first taxable year of the company during such U.S. Holder’s holding period and beginning after January 1, 1987 for which it was a PFIC) would be taxed at the highest tax rate for each such prior year applicable to ordinary income. The Non-electing U.S. Holder also would be liable for interest on the foregoing tax liability for each such prior year calculated as if such liability had been due with respect to each such prior year. A Non-electing U.S. Holder that is not a corporation must treat this interest charge as “personal interest” which, as discussed above, is partially or wholly non-deductible. The balance of the gain or the excess distribution will be treated as ordinary income in the year of the disposition or distribution, and no interest charge will be incurred with respect to such balance.

If we are a PFIC for any taxable year during which a Non-electing U.S. Holder holds common shares, then we will continue to be treated as a PFIC with respect to such common shares, even if we are no longer a PFIC as defined above. A Non-electing U.S. Holder may terminate this deemed PFIC status by electing to recognize a gain (which will be taxed under the rules discussed above for Non-electing U.S. Holders) as if such common shares had been sold on the last day of the last taxable year for which it was a PFIC.

Under Section 1291(f) of the Internal Revenue Code, the Department of the Treasury has issued proposed regulations that would treat as taxable transfers of PFICshares by Non-electing U.S. Holders that are generally not otherwise taxed, such as gifts, exchanges pursuant to corporate reorganizations, and transfers at death. Special, generally adverse, rules will apply with respect to the common shares while the company is a PFIC. For example under Section 1298(b)(6) of the Internal Revenue Code, a U.S. Holder who uses PFICshares as security for a loan (including a margin loan) will, except as may be provided in regulations, be treated as having made a taxable disposition of such shares.

Alternatively, if we are a PFIC, an U.S. Holder (an “Electing U.S. Holder”) who owns common shares is permitted generally to elect out of the tax treatment discussed above, if an U.S. Holder makes a mark-to-market election with respect to common shares. Under such election, an Electing U.S. Holder would generally recognize as ordinary income for each taxable year an amount equal to the excess, if any, of the fair market value of common shares as of the close of the taxable year over the Electing U.S. Holder’s adjusted tax basis in such shares. An Electing U.S. Holder would generally be allowed an ordinary deduction (to the extent of any net mark-to-market gains recognized for prior taxable years) for the excess, if any, of the adjusted tax basis of the common shares over their fair market value as of the close of the taxable year. An Electing U.S. Holder’s adjusted tax basis of the common shares wo uld generally be adjusted to reflect the amounts included or deducted under the mark-to-market election. Additionally, any gain on the actual sale or other disposition of the common shares generally will be treated as ordinary income. Ordinary loss treatment also would generally apply to any loss realized on the actual sale or other disposition of the common shares to the extent that the amount of such loss did not exceed the net mark-to-market gains previously included with respect to such shares. An election to mark to market would generally apply to the taxable year made and all subsequent taxable years. A mark-to-market election is subject to complex and specific rules and requirements, and U.S. Holders are strongly urged to consult their tax advisors concerning such election if the company is classified as a PFIC.

Finally, an U.S. Holder who elects in a timely manner to treat us as a “qualified electing fund” (a “QEF”) as defined in the Internal Revenue Code would be subject to another set of special rules different from those described above. Although a QEF election may be beneficial to some U.S. Holders depending upon their particular tax situations, it requires us to make information available to such holders, and we do not intend to make such information available even if it is classified as a PFIC. Accordingly, the QEF election will not be available to U.S. Holders.

The foregoing discussion is based on existing provisions of the Internal Revenue Code, existing and proposed regulations thereunder, and current administrative ruling and court decisions, all of which are subject to change. Any such change could affect the validity of this discussion. In addition, the implementation of aspects of the PFIC rules requires the issuance of regulations which in many instances have not been promulgated and which may have retroactive effect. There can be no certainty that any of these proposed regulations will be enacted or promulgated and if so, the form they will take or the effect that they may have on this discussion. Accordingly, and due to the complexity of the PFIC rules, U.S. Holders who are shareholders of Diversinet are strongly urged to consult their own tax advisors concerning the impact of these rules on their investment in us.

ITEM 11. Quantitative and Qualitative Disclosure about Market Risk

We believe that inflation has not had a material impact on our results of operations for each of our fiscal years in the three-year period ended December 31, 2005. However, there can be no assurance that future inflation would not have an adverse impact on our operating results and financial condition. We have limited market risk exposure since we do not have any outstanding variable rate debt or derivative financial and commodity instruments as of December 31, 2005.

Since we currently earn revenues and incur expenses in United States dollars and Canadian dollars, exchange rates for these and other local currencies in countries where we may operate in the future may fluctuate in relation to the United States dollar and such fluctuations may have an adverse effect on our earnings or assets when Canadian or local currencies are exchanged for United States dollars. We have not entered into forward foreign exchange contracts. Losses and gains resulting from the translation of revenue and expenses denominated in foreign currencies into United States dollars have been included in our results of operations. For the year ended December 31, 2005, we had a foreign exchange loss of $11,000 compared to $28,000 for the year ended December 31, 2004, and $324,000 for the year ended December 31, 2003.

MANAGEMENT’S REPORT

The accompanying consolidated financial statements and all information in the Annual Report have been prepared by management and have been reviewed and approved by the Board of Directors of the Company. The consolidated financial statements were prepared in accordance with accounting principles generally accepted in Canada and, where appropriate, reflect management’s best estimates and judgments. Management is responsible for the accuracy, integrity and objectivity of the consolidated financial statements within reasonable limits of materiality and for the consistency of financial data included in the text of the Annual Report with that contained in the consolidated financial statements.

To assist management in the discharge of these responsibilities, the Company maintains a system of internal controls and systems designed to provide reasonable assurance that its assets are safeguarded, that only valid and authorized transactions are executed and that accurate, timely and comprehensive financial information is prepared and disclosed. The internal control systems and financial records are subject to reviews by external auditors during the examination of the financial statements. Management recognizes its responsibility for conducting the Company’s affairs to comply with the requirements of applicable laws and established financial standards and principles, and for maintaining proper standards of conduct in its activities.

The Company’s Audit Committee is appointed by the Board of Directors annually and is comprised of three non-management directors. The Audit Committee meets with management as well as with the independent auditors to satisfy itself that management is properly discharging its financial reporting responsibilities and to review the consolidated financial statements and the independent auditors’ report. The Audit Committee reports its findings to the Board of Directors for consideration in approving the consolidated financial statements for presentation to the shareholders. The Audit Committee has responsibility for engaging or re-appointing the Company’s independent auditors. The independent auditors have direct and unrestricted access to the Audit Committee to discuss their audit and related findings as to the integrity of the Company’s financial reporting.

AUDITORS’ REPORT TO THE SHAREHOLDERS

We have audited the consolidated balance sheets of Diversinet Corp. as at December 31, 2005 and December 31, 2004 and the consolidated statements of earnings and deficit and cash flows for each of the years ended December 31, 2005, December 31, 2004 and December 31, 2003. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform an audit to obtain reasonable assurance 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.

In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the Company as at December 31, 2005 and December 31, 2004 and the results of its operations and its cash flows for each of the years ended December 31, 2005, December 31, 2004, and December 31, 2003 in accordance with Canadian generally accepted accounting principles.

COMMENTS BY AUDITORS FOR U.S. READERS ON CANADA - U.S. REPORTING DIFFERENCE

In the United States, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when the financial statements are affected by conditions and events that cast substantial doubt on the Company’s ability to continue as a going concern, such as those described in note 1 to the financial statements. Our report to the shareholders dated February 22, 2006, is expressed in accordance with Canadian reporting standards which do not permit a reference to such events and conditions in the auditors’ report when these are adequately disclosed in the financial statements.

Notes to Consolidated Financial Statements

(In United States dollars)

Years ended December 31, 2005 and 2004

Diversinet Corp. (the “Company”), an Ontario corporation, develops, markets and distributes wireless security infrastructure solutions and identity management solutions and professional services to the enterprise, financial services, government and gaming and wagering marketplaces.

Future operations:

These consolidated financial statements have been prepared on a going concern basis, which assumes the Company will continue in operation for the foreseeable future and be able to realize assets and satisfy liabilities in its normal course of business. Certain conditions and events exist that cast substantial doubt on the Company’s ability to continue as a going concern.

The Company has incurred significant losses and used significant amounts of cash in operating activities in recent years.

Continued operations depend upon the Company’s ability to generate future profitable operations and/or obtain additional financing to fund future operations and, ultimately, to generate positive cash flows from operating activities. There can be no assurance that the Company will be successful in obtaining additional financing or generating positive cash flows from operations.

Should the Company be unable to generate positive cash flows from operations or secure additional financing in the foreseeable future, the application of the going concern principle for financial statement reporting purposes may no longer be appropriate. These financial statements do not include any adjustments related to the valuation or classification of recorded asset amounts or the amounts or classification of liabilities that may be necessary should the Company be unable to continue as a going concern.

Significant accounting policies:

These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in Canada, which, except as described in note 16, conform in all material respects with accounting principles generally accepted in the United States. Significant accounting policies adopted by the Company are as follows:

(a)

Basis of consolidation:

The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany transactions and balances have been eliminated.

(b)

Goodwill and customer assets:

Goodwill is the residual amount that results when the purchase price of an acquired business exceeds the sum of the amounts allocated to the identifiable tangible and intangible assets acquired, less liabilities assumed, based on their fair values. When the Company enters into a business combination, the purchase method of accounting is used. Goodwill is assigned as of the date of the business combination to reporting units that are expected to benefit from the business combination. Goodwill is not amortized but instead is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test is carried out in two steps. In the first step, the carrying amount of the reporting unit, including goodwill, is compared with its fair value. When the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered to be impaired and the second step of the impairment test is unnecessary. The second step is carried out when the carrying amount of reporting unit exceeds its fair value, in which case, the implied fair value of the reporting unit’s goodwill, determined in the same manner as the value of goodwill is determined in a business combination, is compared with its carrying amount to measure the amount of the impairment loss, if any.

During the third quarter of 2005, a Caradas customer contract expired and accordingly a goodwill and customer asset impairment analysis was performed for the Caradas reporting unit. The impairment analysis indicated that the fair values of goodwill and customer assets were nil, and the Company recorded a goodwill write down of $1,894,690 and a customer assets write down of $330,768. The impairment analysis for DSS indicated that the fair value of goodwill was nil and accordingly recorded an impairment charge of $392,242. Application of the goodwill impairment test requires judgment, including assignment of assets and liabilities and determination of the fair value of each reporting unit. The fair value of each reporting unit is estimated using a discounted cash flow methodology. This requires significant judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, the useful life over which cash flows will occur, and determination of discount rate and terminal asset value. The Company believes goodwill is recorded at its fair value as at December 31, 2005.

The changes in the carrying amount of goodwill for the years ended December 31, 2005 and 2004 are as follows:

Balance December 31, 2003	$ 5,311,932
Goodwill impairment charge	(3,025,000)
Balance December 31, 2004	2,286,932
Goodwill impairment charge	(2,286,932)
Balance December 31, 2005	$ –

(c)

Impairment or disposal of long-lived assets:

The Company reviews capital and intangible assets (long-lived assets) for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Absent any triggering factors during the year, the Company conducts its long-lived asset assessment in the fourth quarter to correspond with its planning cycle. An impairment loss is recognized when the carrying amount of an asset that is held and used exceeds the projected undiscounted future cash flows expected from its use and disposal, and is measured as the amount by which the carrying amount of the asset exceeds its fair value which is measured by discounted cash flows when quoted market prices are not available. For assets available-for-sale, an impairment loss is recognized when the carrying amount exceeds the fair value less costs to sell.

(d)

Revenue recognition:

The majority of our revenues are derived from consulting services delivered on a stand alone basis. We also provide technical consulting services relating to smart card based application security systems. We also derive revenues from products and services for mobile commerce over wireless networks.

Consulting revenues are recognized on a time and materials basis, or on a percentage of completion basis, depending on the specifics of the contract, as employees and subcontractors provide services. Revenue from time and materials service contracts are recognized as the services are provided. Revenue from long term contracts is recognized based on actual hours incurred as specific deliverables are achieved, consistent with the Company’s proportional performance under the contractual arrangement. Losses on contracts are recognized during the period in which the loss first becomes probable and reasonably estimable. Contract losses are determined to be the amount by which the estimated direct and indirect costs of the contract exceed the estimated total revenues that will be generated by the contract. Revenue recognized in excess of billings is recorded as unbille d services. Billings in excess of revenue recognized are recorded as deferred revenue until the above revenue recognition criteria are met. Reimbursements, including those relating to travel and other out-of-pocket expenses, and other similar third-party costs, are included in revenues.

Revenue from software license agreements is recognized in accordance with CICA 3400 “Revenue” and Statement of Position 97-2 “Software Revenue Recognition” as amended upon execution of a license agreement and the shipment of the software, as long as all vendor obligations have been satisfied, the license fee is fixed and determinable and collection of the license fees is probable. We consider fees related to arrangements with significant payments due beyond our normal trading terms not to be fixed or determinable. If the fee is not fixed or determinable, revenue is recognized as the payments become due from the customer. If collectibility is not considered probable, revenue is recognized when the fee is collected. Revenue from the sale of additional software products is recognized as software is delivered.

Revenue earned on software arrangements involving multiple elements (i.e., software products, upgrades/enhancements, post contract customer support, installation, training, et cetera) is allocated to each element based on vendor specific objective evidence (VSOE) of relative fair value of the elements. When arrangements contain multiple elements and VSOE only exists for all undelivered elements, the Company recognizes revenue for the delivered elements using the residual method, whereby the total arrangement fee is assigned to the undelivered elements based on their fair value, with the residual assigned to the delivered elements and recognized. VSOE used in determining the fair value for installation, integration and training is based on the standard daily rates for the type of service being provided multiplied by the estimated time to complete the task. VSOE used i n determining the fair value of maintenance and technical support is based on annual renewal rates. For arrangements containing multiple elements where VSOE does not exist for all undelivered elements, revenue for the delivered and undelivered elements is deferred until either VSOE exists for the remaining undelivered elements or all elements have been delivered. The revenue allocated to post contract customer support is recognized ratably over the term of the support and revenue allocated to service elements (such as training and installation) is recognized as the services are performed.

The Company’s sales arrangements generally include standard payment terms ranging up to 90 days. The Company provides a limited product warranty, the costs of which have historically been insignificant. The Company’s products are not subject to rights of return, stock rotation rights or price protection.

(e)

Cash and cash equivalents:

Cash and cash equivalents include cash on account and short-term investments in money market instruments with original maturities of 90 days or less when acquired.

(f)

Short-term investments:

Short-term investments consist of corporate debt securities having a term of 90 days but less than one year when acquired which are recorded at cost plus accrued interest.

(g)

Investment tax credits:

Investment tax credits are accrued when qualifying expenditures are made and there is reasonable assurance that the credits will be realized. Investment tax credits earned with respect to current expenditures for qualified research and development activities are included in the consolidated statements of earnings and deficit as a reduction of related expenses in the year incurred. Assistance related to the acquisition of capital assets used for research and development is credited against the related capital assets. The Company has recorded no investment tax credits in 2005 ($141,000 - 2004).

(h)

Research and development costs:

Research costs are expensed as incurred. Software development costs are deferred once costs meet the criteria under Canadian generally accepted accounting principles for deferral and amortization. Such deferred costs are amortized, commencing when the product is commercially released, on a straight-line basis over two years. The recoverability of any unamortized deferred development costs is reviewed on an ongoing basis.

(i)

Purchased and acquired technology:

The Company capitalizes purchased technology and amortizes such costs over two years. The carrying value is assessed on a periodic basis to determine if a write-down is required. During the year, the Company recorded amortization of purchased technology and customer assets in the amount of $126,000 ($189,000 for 2004) and $221,000 ($331,000 for 2004), respectively.

(j)

Customer assets:

Customer relationships are amortized over three years. Customer contracts are amortized as services are performed. The carrying value is accessed on a periodic basis to determine if a write-down is required.

(k)

Foreign currency translation:

Monetary assets and liabilities denominated in foreign currencies are translated into United States dollars at the exchange rates prevailing at the consolidated balance sheet dates. Non-monetary assets and liabilities are translated at historical rates. Transactions in foreign currencies are translated into United States dollars at the approximate rates prevailing at the dates of the transactions. Foreign exchange gains and losses are included in loss for the period.

As a result of a number of circumstances, including the financing activities during fiscal 2003, the acquisition of DSS Software Technologies and Caradas, Inc. and the U.S. dollar becoming the measurement currency in which most of the Company’s business is transacted, effective October 1, 2003, the Company adopted the U.S. dollar as its measurement and reporting currency for preparation of its consolidated financial statements

Under this method, share capital was translated at the exchange rate in effect at the time of the transaction. Deficit was translated at the approximate rates prevailing at the dates of the transactions and monetary assets and liabilities were translated into United States dollars at the exchange rates prevailing at the consolidated balance sheet dates. The resulting difference has been classified as a cumulative translation adjustment on the balance sheet.

(l)

Capital assets:

Capital assets are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is provided over the estimated useful lives of the assets at the following annual rates and bases:

Asset	Basis	Rate
Computer hardware	Declining balance	30%
Computer software	Declining balance	30%
Furniture and fixtures	Declining balance	20%
Leasehold improvements	Straight-line	Over term of lease

(m)

Income taxes:

The Company accounts for income taxes using the asset and liability method. Under this method, future income taxes are recognized at the enacted or substantively enacted tax rate expected to be applicable at the date of reversal for all significant temporary differences between the tax and accounting bases of assets and liabilities and for certain tax carry forward items. Future income tax assets are recognized only to the extent that, in the opinion of management, it is more likely than not that the future income tax assets will be realized. Future income tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of the substantive enactment of the change.

(n)

Earnings per share:

Basic earnings per share is computed using the weighted average number of common shares that are outstanding during the year. Diluted earnings per share is computed using the weighted average number of common and potential common shares outstanding during the year. Potential common shares consist of the incremental number of common shares issuable upon the exercise of stock options and warrants and are calculated using the treasury stock method.

(o)

Stock-based compensation:

Effective January 1, 2004, Canadian GAAP requires the Company to estimate the fair value of stock-based compensation granted to employees and to expense the fair value over the estimated vesting period of the stock options. In accordance with the transition rules, the Company has retroactively adopted this change without re-statement of prior years and has determined the fair value of stock options granted to employees since November 1, 2002 in the amount of $186,887, representing the expense for the 2003 fiscal year. This amount has been charged to deficit with an offsetting increase to the contributed surplus. During the year ended December 31, 2005, the Company recorded compensation expense for Canadian GAAP of $439,250 (2004 - $577,549) relating to employee stock options for which there was no corresponding expense under US GAAP (note 14).

Management considers projected future taxable income, uncertainties related to the industry in which the Company operates and tax planning strategies in making this assessment.

Commitments and contingencies:

(a)

Litigation:

Management is of the opinion that the claims listed below are without merit and will not materially impact the Company. As a result, no provision for loss has been made in these consolidated financial statements.

(i)

During fiscal 2000, the Company and its wholly owned Barbados subsidiary, The Instant Publisher Ltd., were sued by a company that alleged that the Company breached a dealer agreement entered into in 1995 by the Company’s former printing business and is seeking damages of $1,533,950 and damages of $25,000,000 for loss of reputation and loss of opportunity, pre-judgment and post-judgment interest, and costs.

(ii)

In addition to the above, in the ordinary course of business, the Company and its subsidiaries have legal proceedings brought against them.

(b)

Lease commitments:

Total future minimum lease payments including operating costs are as follows:

2006	379,639
	$ 379,639

Share option plan:

The Company grants options to certain employees, officers, directors and consultants under a share option plan (the “Plan”), enabling them to purchase common shares of the Company. The exercise price of an option under the Plan may not be less than the current market price of common shares on the day immediately proceeding the day the share option was granted. The Plan provides that the number of common shares reserved for issuance under the Plan shall not exceed 2,896,250 common shares (being 3,144,788 options reserved for issuance less 248,538 exercised to date). During 2005, the Company reduced the stock option vesting period from three years to two years (which has correspondingly shortened the expense amortization period) and also started to compensate Directors with stock grants or cash and option grants. This has increased compensation expense. As at December 31, 2005, the number of common shares reserved for future issues of stock options amounts to 486,379.

Assumptions used when valuing the options and warrants at their date of grant using the Black-Scholes option pricing model include: risk-free interest rate of 3.092%, estimated life of three years, expected divided yield of 0% and volatility of 150%.

Financial instruments and risk management:

The Company is exposed to the following risks related to financial assets and liabilities:

(a)

Currency risk:

The Company is subject to currency risk through its activities in Canada, United Kingdom, Europe and Asia. Unfavourable changes in the exchange rate may affect the operating results of the Company.

The Company does not actively use derivative instruments to reduce its exposure to foreign currency risk. However, dependent on the nature, amount and timing of foreign currency receipts and payments, the Company may enter into forward exchange contracts to mitigate the associated risks. The Company has not entered into such contracts at December 31, 2005 and 2004.

(b)

Fair values:

The fair values of the Company’s financial instruments approximate their carrying amounts due to their short-term nature.

(c)

Credit risk:

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash equivalents, short-term investments and accounts receivable. Cash equivalents and short-term investments are maintained at high-quality financial institutions.

The Company generally does not require collateral for sales on credit. The Company closely monitors extensions of credit. Management assesses the need for allowances for potential credit losses by considering the credit risk of specific customers, historical trends and other information.

(a)

Share capital and deficit:

On March 1, 1999, the shareholders approved a resolution to reduce the stated capital of the Company by $30,089,054 to eliminate the deficit as at October 31, 1999. Under Canadian GAAP, a reduction of the carrying amount of share capital of outstanding common shares is allowed with a corresponding offset to deficit. This reclassification, which the Company made in 2000 to eliminate the deficit that existed at October 31, 1999, did not meet the criteria specified by U.S. GAAP and results in an increase to share capital with a corresponding increase in deficit of $30,089,054.

(b)

Compensation expense:

(i)

Effective November 1, 2002, the Company adopted the new CICA Handbook section 3870, “Stock-Based compensation and Other Stock Based Payments”. As a result, the Company has recognized compensation expense on options issued to consultants subsequent to November 1, 2002. As the Company has always recognized compensation expense for options issued to consultants for US GAAP purposes, this resulted in no U.S. GAAP differences in 2005 and 2004. Prior to the adoption of 3870, the company did not recognize compensation expense for Canadian GAAP purposes when stock or stock options were issued to consultants. Any consideration paid on exercise of stock options or purchase of stock was credited to share capital.

(ii)

Effective January 1, 2004 Canadian GAAP requires the Company to estimate the fair value of stock-based compensation granted to employees and to expense this amount over the estimated vesting period of stock options. For US GAAP purposes, the Company follows the intrinsic value method and no stock based compensation is recorded when the exercise price of stock options granted to employees is the same as the market price at the date of grant. If the Company issues options with an exercise price that is less than the market price, for US GAAP purposes the resulting compensation expense is charged to earnings over the vesting period. During the year ended December 31, 2005, the Company recorded compensation expense for Canadian GAAP of $439,250 (2004 - $577,549) relating to employee stock options in excess of the amount recorded under US GAAP.

(a)

Other comprehensive loss (income):

FASB Statement of Financial Accounting Standards No. 130, “Reporting Comprehensive Income” (SFAS 130”) requires disclosure of comprehensive income, which includes reported net income as adjusted for other comprehensive income. Other comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources.

(e)

Short-term investments:

Short-term investments consist of corporate debt securities. For U.S. GAAP purposes, the Company classifies its debt securities as available-for-sale, which are recorded at fair value.

Unrealized holding gains and losses, net of the related tax effect, on available-for-sale securities are excluded from earnings and are reported as a separate component of other comprehensive income until realized. Realized gains and losses from the sale of available-for-sale securities are determined on a specific identification basis. During the periods presented, there have been no unrealized holding gains or losses on short-term investments.

A decline in the market value of any available-for-sale security below cost that is deemed to be other than temporary results in a reduction in carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established.

(f)

Notes to consolidated financial statements:

In order to comply with U.S. GAAP, the following notes to the consolidated financial statements would need to be added:

(i)

Stock-based compensation plan:

SFAS No. 123, Accounting for Stock-Based Compensation, requires pro forma disclosures of net income and earnings per share, as if the fair value-based method as opposed to the intrinsic value-based method of accounting for employee stock options had been applied. The disclosures in the following table show the Company’s loss for the year and loss per share on a pro forma basis using the fair value method as determined by using the Black-Scholes option-pricing model. Assumptions used when valuing the options at their date of grant using in the Black-Scholes option pricing model include: risk-free interest rate of 3.092%, estimated life of three years, expected divided yield of 0% and volatility of 150%.

	2005	2004	2003
Loss under U.S. GAAP	$ (6,670,246)	$ (6,939,293)	$ (4,958,751)
Compensation expense	804,158	673,513	1,281,680
Pro forma loss under U.S. GAAP	(7,474,404)	(7,612,806)	(6,240,431)
Pro forma loss per common share:
Basic and diluted	(0.36)	(0.63)	(0.89)
Weighted average number of common shares	20,578,427	12,144,565	7,022,447

(ii)

Recent accounting pronouncements:

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections” (“SFAS 154”), which replaces Accounting Principles Board Opinion No. 20, “Accounting Changes”, and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements”. SFAS 154 provides guidance on the accounting for and reporting of changes in accounting principles and error corrections. SFAS 154 requires retrospective application to prior period’s financial statements of voluntary changes in accounting principle and changes required by new accounting standards when the standard does not include specific transition provisions, unless it is impracticable to do so. Certain disclosures are also required for restatements due to correction of an error. SFAS 154 is effective for accounting changes and corrections of errors, made in fiscal years be ginning after December 15, 2005. The impact that the adoption of SFAS 154 will have on the Company’s results of operations and financial condition will depend on the nature of future accounting changes and the nature of transitional guidance provided in future accounting pronouncements.
