D. Risk Factors

A further decline in information technology spending may result in a decrease in our revenues or lower growth rates.

      The recent slowdown in global economies has negatively affected the level of spending of our customers on information technology (IT) solutions. We cannot predict if or when the growth rate of worldwide economies will accelerate, or when or if demand for IT solutions will increase. A further decline or lack of growth in the demand for IT solutions may result in decreased revenues or lower growth rates because our sales depend in part on our customers’ level of funding for new or additional IT systems or services. Sustained economic downturn may cause our customers to reduce or eliminate IT spending, which would substantially reduce the number of new software licenses we sell. An economic downturn may also cause price erosion for our products, which would reduce the average sales price for these licenses.

-3-

      In addition, actual or threatened terrorist attacks, military actions and events or effects occurring in response to those developments may reduce the amount or delay the timing of capital expenditures by corporations for IT solutions. Accordingly, we cannot be assured that we will be able to increase or maintain our revenues.

Our lengthy and variable sales cycle makes it difficult to predict our operating results.

      It is difficult to forecast the timing and recognition of our revenues because our prospective customers often dedicate a significant amount of time to evaluating our products before licensing them. The period between initial customer contact and purchase by a customer may extend to twelve months or more. During the evaluation process, prospective customers may decide not to purchase or may scale down proposed orders of our products for various reasons including:

• reduced demand for our products or for integration software generally;

• introduction of products by our competitors;

• lower prices offered by our competitors;

• changes in budgets and purchasing priorities; and

• changes by prospective customers in their approach with respect to the integration of enterprise applications.

We may experience fluctuations in quarterly revenue that could adversely impact our operating results.

      Our revenues and operating results are difficult to predict and may fluctuate significantly from quarter to quarter. Historically, our product revenue in the first quarter of each year has declined from the fourth quarter of the prior year. Revenue in any quarter depends substantially upon our ability to sign contracts and our ability to recognize revenues in that quarter in accordance with revenue recognition policies. Therefore, you should not rely on period to period comparisons of revenues or results of operations as an indication of future performance. If our quarterly revenues or operating results fall below expectations of investors or securities analysts, the price of our ordinary shares and ADSs could fall substantially.

      Our quarterly revenues may fluctuate as a result of a variety of factors, including the following:

• a significant number of our prospective customers decide whether to enter into license agreements with us within the last month of each quarter;

• the size of transactions can vary significantly;

• the demand for our products may change;

• customers may unexpectedly postpone orders due to changes in their strategic priorities, project objectives, budget or personnel;

• customer evaluations and purchasing processes vary significantly from company to company, and a customer’s internal approval and expenditure authorization process can be difficult and time consuming to complete, even after selection of a vendor;

• the number, timing and significance of product enhancements and new product announcements by us and our competitors may affect purchase decisions; and

• we may have to defer revenues under our revenue recognition policies.

      Fluctuations in our quarterly revenues may adversely affect our operating results. In each fiscal quarter our expense levels, operating costs and hiring plans are based on projections of future revenues and are relatively fixed. If our actual revenues fall below expectations, we could experience a reduction in operating results.

-4-

We have experienced significant variations in profitability and anticipate that we will continue to do so in the future.

      Our levels of profitability have varied significantly on a quarterly and annual basis. These variations were attributable to fluctuations in revenue and costs, including costs associated with the development and introduction of new products and services, charges associated with acquisitions, and certain non-recurring expenses attributable to the settlement of litigation, restructuring and impairment of goodwill, other non-current assets and fixed assets. There can be no certainty that we will not experience similar variations in profitability in future periods for these or other factors, and any such variation could have a significant impact on the market value of our ordinary shares and ADSs.

Our future revenue depends upon the evolution and adoption of Web services and related integration and infrastructure solutions.

      We believe that large organizations will continue to adopt Web services and related integration and infrastructure solutions, including enterprise service bus (ESB) products. Therefore, we have invested significant amounts in developing and introducing products to meet the development, deployment and integration requirements of enterprises using Web services for integration and service-oriented architectures. If the enterprise adoption of Web services, and Web services based ESBs, for these purposes does not evolve as we anticipate or fails to grow as quickly as we expect, we may be unable to implement our strategy or achieve the growth rate that we target.

      The acceptance of our Artix family of ESB products also depends upon the development and proliferation of Web services standards for application integration. If these standards do not continue to develop or are not widely accepted, the demand for our products and services may not materialize. Consequently, our business prospects and financial condition would suffer.

If we fail to keep pace with rapidly evolving technology and changing customer needs, our business will suffer.

      The market for enterprise infrastructure software is characterized by rapidly changing technology, evolving industry standards and changing customer needs. Therefore, our success will depend upon our ability to enhance our existing products and to introduce and market new products to meet changing customer requirements on a timely and cost-effective basis. If we experience delays in the introduction of new or enhanced products, or if we are unable to anticipate or respond adequately to these changes, our products could be rendered obsolete and our business could be materially harmed.

Potential defects in our products or our failure to provide services for our customers could cause our sales to decrease, cause us to lose customers and damage our reputation.

      The products that we offer include newly-launched products with a nascent customer adoption record. These products may contain defects that may be detected at any point in the product’s life cycle. We have in the past discovered errors in certain of our product enhancements and new products and have experienced delays in generating revenue while correcting these errors. Our products are often used in combination with products of other vendors. As a result, it may be difficult to identify the source of any problem. If defects occur, we could experience, among other things:

•  loss of customers;

•  injury to our reputation;

•  loss or delay of market acceptance or sales;

•  increased service or warranty costs; or

•  legal action by our customers.

-5-

      In addition, we may not be able to avoid or limit liability for disputes relating to product performance or provision of services.

If we do not manage our expenses and geographically dispersed operations successfully, we may be unable to respond to changing market conditions.

      The IT integration market is becoming increasingly volatile. To address this volatility and global economic conditions generally, we have taken measures to bring our workforce, staffing and structure in line with perceived current demand for our products. If we misjudge our personnel needs or cannot successfully manage our expenses, then our business, financial condition and results of operations would be materially adversely affected. Our future operating results will depend substantially upon the ability of our officers and key employees to anticipate changing business conditions and manage personnel and other costs while increasing sales.

      We face additional risks in managing geographically dispersed operations. Some of our key executives and managers are based in our Dublin, Ireland headquarters and others in our wholly-owned U.S. subsidiary’s Waltham, Massachusetts office. Accordingly, our ability to compete successfully will depend in part on the ability of a limited number of key executives located in geographically dispersed offices to integrate management, to address the needs of our worldwide customer base and to respond to changes in our market. In addition, our ability to manage our operations and financial performance would be materially adversely affected if terrorist attacks or military or other political events prohibit or restrict the travel of our personnel.

We may be required to delay the recognition of revenue until future periods which could adversely impact our operating results.

      We may have to defer revenue recognition due to several factors, including whether:

•  we are required to accept extended payment terms;

•  the transaction involves contingent payment terms or fees;

•  the transaction involves acceptance criteria or there are identified product-related issues; or

•  license agreements include products that are under development or other undelivered elements.

      Because of the factors listed above and other specific requirements under U.S. GAAP for software revenue recognition, we must have very precise terms in our license agreements to recognize revenue when we initially deliver our products or perform services. Negotiation of mutually acceptable terms and conditions can extend the sales cycle, and sometimes we do not obtain terms and conditions that permit revenue recognition at the time of delivery or even as work on the project is completed.

We depend on large transactions to derive a significant portion of our revenue, and the delay or loss of any large customer order could adversely affect our quarterly or annual operating results.

      We derive a significant portion of our revenue from large transactions. Customers face complex decisions regarding approaches to the development, deployment and integration of enterprise applications, competitive product offerings, rapidly changing software technologies, and limited internal resources. We must often negotiate terms and conditions in large sales transactions. These terms and conditions can extend the sales cycle and, in certain situations, result in deferred recognition of revenue from the sale. Prospective sales are subject to delays or cancellation over which we have little or no control. If any large customer order anticipated for a particular quarter is not realized or is delayed, we may experience an unplanned shortfall in revenue, which could significantly and adversely affect our operating results.

We currently derive most of our revenue from a limited number of our products.

      To date, we have derived most of our revenue from the licensing of our products that currently compose our Orbix and Artix products and fees from related services. We expect our Orbix products to

-6-

continue to account for a substantial majority of our revenue for the foreseeable future. As a result, a reduction in demand for, or sales of, these products would have a material adverse effect on our business, financial condition and results of operations. In addition, our business will depend, in significant part, on the successful development, introduction and customer acceptance of new and enhanced versions of our products. We may not successfully develop, introduce or market new products or enhancements or additions to our existing products. Any failure to do so would materially adversely affect our business, financial condition and results of operations.

If we do not successfully expand and manage our direct sales force and other distribution channels, we may not be able to increase our sales.

      To date, we have sold our products primarily through our direct sales force, software vendors and system integrators. We plan to continue to invest in, and rely on sales through, these distribution channels and other indirect channels. We experience lower profit margins on the distribution of our products through third-party distribution channels. We may not be able to expand or manage successfully our direct sales force or other distribution channels. Further, any such expansion may not result in an increase in revenue or operating income. If we fail to expand or manage successfully our direct sales force or other distribution channels, our business, financial condition and results of operations would materially suffer.

Our inability to create and preserve relationships with software vendors, system integrators or other third parties that market and sell our products could reduce our revenues.

      Our ability to achieve revenue growth will depend in large part on expanding our sales channels, as well as leveraging our existing strategic alliances. If our relationships with these software vendors or system integrators deteriorate or terminate, or if we are unable to form new relationships, we may lose important sales and marketing opportunities. Our distribution arrangements could give rise to disputes regarding marketing strategy, exclusive territories and customer relationships which could negatively affect our business or result in costly litigation. In addition, if these software vendors and system integrators are unable to recruit and adequately train a sufficient number of consulting personnel to support the implementation of our software products, or they otherwise do not adequately perform implementation services, we may lose customers. These system integrators may increase their promotion of competing enterprise integration solutions or may otherwise discontinue their relationships with or support of us. Our relationships with software vendors and system integrators are an important part of our business, and a deterioration of these relationships could adversely impact our business and operating results.

      We also may enter into joint arrangements with strategic partners to develop new products or enhancements, or to license our offerings as part of integrated products. Our business may be adversely affected if these strategic partners change their business priorities or experience difficulties in their operations, which in either case causes them to terminate or reduce their support for these joint arrangements.

We operate in highly competitive markets and we may be unable to compete successfully.

      The market for enterprise infrastructure software solutions is highly competitive. We expect this competition to increase. Our products compete with offerings from a number of established infrastructure vendors, as well as offerings from new software companies. Some of these companies offer products that compete with single components of our product set, while other companies market a set of products designed to solve broad integration problems.

      We compete principally against vendors of:

•  enterprise infrastructure software;

•  enterprise application integration software;

•  Web services integration software;

-7-

•  enterprise service bus software (ESB); and

•  open source software projects and products.

      We believe that our ability to compete depends in part on a number of factors outside of our control, including:

•  the demand for our products;

•  the development by others of software that is competitive with our products;

•  the price at which others offer comparable products;

•  the ability of our competitors to respond effectively to customer needs;

•  the ability of our competitors to market their products aggressively and effectively; and

•  the ability of our competitors to hire, retain and motivate key personnel.

      In addition, a number of our competitors have substantially greater technical, financial, sales, marketing, customer support, professional services and other resources, as well as greater name recognition, than we do. As a result, our competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements, to devote greater resources to the promotion and sale of their products, or to establish more successful strategic relationships with industry leaders and other third parties than we can. Further, certain of our larger competitors may be able to offer competitive products or technologies as part of their broader product or service offerings or may make strategic acquisitions or establish cooperative relationships among themselves or with third parties, thereby increasing the ability of their products to address the needs of our current and prospective customers. Accordingly, it is possible that new competitors or alliances among our current and potential competitors may emerge and rapidly gain significant market share. This type of competition could materially adversely affect our ability to license products and provide services on terms favorable to us. In addition, among our smaller competitors, the competition for retaining market share is intense. Due to competitive pressures, we could be forced to reduce the price of our products and related services. Lower sales or reduced prices would negatively impact our operating results and financial condition.

      Many of our competitors have a significant installed base that includes our current and potential customers. Once a customer has installed the products of one of our competitors, it may be difficult to convince the customer to adopt or purchase our products. If we are unable to further penetrate our existing customer base or sell to new clients, our business prospects and financial condition would suffer.

If we are unable to attract and retain highly qualified personnel, our future results would be adversely affected.

      We depend to a significant extent upon a limited number of senior executives. We face intense competition for highly qualified personnel. If we fail to attract, retain or assimilate key personnel, our business, financial condition and results of operations would materially suffer.

We face various risks associated with our international operations that could cause our operating results to suffer.

      We are incorporated in Ireland and substantial portions of our product development, marketing, sales and administrative functions are located in Ireland. Our sales are derived, and our operations are conducted, worldwide. We expect that operations outside of the United States will continue to account for a significant portion of our business and expect to continue to expand our operations outside of the United States. Because of the international character of our business, we are subject to risks such as:

•  fluctuations in currency exchange rates;

•  political and economic conditions in various jurisdictions;

-8-

•  unexpected changes in regulatory requirements, tariffs and other trade barriers;

•  failure to enter into relationships with local resellers, system integrators or other third party vendors, or to introduce localized products;

•  difficulties in staffing and managing foreign operations;

•  longer accounts receivable payment cycles; and

•  differing laws affecting the enforceability of intellectual property rights and product liability.

      If any of these risks materializes, revenue derived from customers outside the United States could decrease, and our business, financial condition and results of operations could materially suffer.

We may be unable to identify or complete suitable acquisitions, and any acquisitions we do complete may create business difficulties or dilute our shareholders.

      As part of our business strategy, we may pursue strategic acquisitions. We may be unable to identify suitable acquisition candidates. We cannot assure you that we will be able to make acquisitions on commercially acceptable terms or at all. If we acquire a business, technology or product, we may have difficulty integrating that business, technology or product with our existing operations or our software. These difficulties could disrupt our ongoing business, distract our management and workforce, increase our expenses and adversely affect our operating results. In addition, the key personnel of an acquired entity may decide not to work for us. We may also incorrectly judge the value or worth of an acquired business, technology or product. Furthermore, we may incur significant debt or be required to issue equity securities to pay for future acquisitions or investments. The issuance of equity securities may be dilutive to our shareholders.

If our effective tax rate increases, our business and financial results would be adversely impacted.

      We have significant operations and generate a substantial portion of our taxable income in Ireland. In general, the tax rate in Ireland on trading income, which is 12.5% with effect from January 1, 2003, is significantly lower than U.S. tax rates. Moreover, our Irish taxable income derived from software substantially developed in Ireland is taxed at a 10% effective tax rate. If our operations no longer qualify for these lower tax rates or if the tax laws were rescinded or changed, our effective tax rate would increase and our business, financial condition and results of operations could be materially adversely affected. In addition, if Japanese, U.S., U.K., German, Australian or other tax authorities were to challenge successfully the manner in which we recognize profits or, more generally, the jurisdiction in which our income is subject to taxation, our effective tax rate could increase and our cash flow and results of operations could be materially adversely affected. If our revenues fail to grow we will become increasingly dependent on favorable tax rates to maintain our earnings.

Our U.S. holders of our ordinary shares or ADSs could suffer adverse tax consequences if we are characterized as a passive foreign investment company.

      If, for any taxable year, our passive income or our assets that produce passive income exceed levels provided by law, we may be characterized as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes. This characterization could result in adverse U.S. tax consequences to the holders of our ordinary shares or ADSs. U.S. persons should consult with their own U.S. tax advisors with respect to the U.S. tax consequences of investing in our ordinary shares or ADSs.

The rights of shareholders in Irish corporations may be more limited than the rights of shareholders in U.S. corporations.

      The rights of holders of our ordinary shares and, therefore, some of the rights of the holders of our ADSs are governed by Irish law and the laws of the European Union. As a result, the rights of our shareholders differ from, and may be more limited than, the rights of shareholders in typical

-9-

U.S. corporations. In particular, Irish law significantly limits the circumstances under which shareholders of Irish corporations may bring derivative actions.

We have a limited ability to protect our intellectual property rights, and others could obtain and use our technology without our authorization.

      We regard certain of our technologies as proprietary, and we rely primarily on a combination of patent, copyright, trademark and trade secret laws, employee and third-party non-disclosure agreements, and technical measures to establish and protect our proprietary rights. The laws of various countries in which our products may be licensed may not protect our proprietary rights to the same extent as the laws of the United States and Ireland. While we generally enter into confidentiality agreements and limit access to, and distribution of, our proprietary information, it is possible for a third party to copy or otherwise obtain and use our technology without authorization. Third parties may reproduce our software products without our consent. In addition, it is possible that our means of protecting our proprietary rights will not be adequate. Any unauthorized reproduction of our software or inadequate protection of our proprietary rights could have a material adverse effect on our business, financial condition or results of operations.

If we do not have the right to use third-party technology, we may have to stop selling and shipping products and incur significant development or license expenses.

      We use and incorporate third-party technology in our products. If we do not have adequate rights to use this technology or our rights terminate, we could be required to:

•  stop using the third-party technology;

•  stop selling and shipping our products in which the third-party technology is used; or

•  incur significant expenses to identify and obtain replacement technology or develop similar technology or to obtain a new license to the third-party technology.

      We may not be able to develop technology or identify other technology with functionality similar to this third-party technology. In addition, we may not be able to obtain a license to this third-party technology on acceptable terms or at all, and we may be liable for damages in the event of any unauthorized use. If any of these events occur, our business, financial condition and results of operations could be materially adversely affected.

We may be exposed to significant liability if we infringe upon the intellectual property or proprietary rights of others.

      Third parties have notified us, and others may notify us, from time to time, that they believe we are infringing certain of their patents and other intellectual property rights. The cost of responding to any such assertion may be material, whether or not the assertion is valid. In the event that any such assertion is resolved adversely to us, we could be required to:

•  discontinue the use of certain processes;

•  cease the use and sale of infringing products and services;

•  expend significant resources to develop non-infringing technology;

•  obtain licenses to competing technology; or

•  indemnify customers under certain clauses relating to intellectual property rights in our licenses.

      We may be unable to obtain licenses on acceptable terms or at all. We may become a party to litigation, and the court may assess damages. If we fail to obtain licenses, if adverse or protracted litigation arises out of any such assertion or damages are assessed, our business, financial condition or results of operations could be materially adversely affected.

Changes in the accounting treatment of stock options could adversely affect our results of operations.

      In December 2004, and as amended in April 2005, the Financial Accounting Standards Board issued SFAS No. 123R,Share-Based Payment to require companies to expense employee stock options for financial reporting purposes, effective for fiscal years beginning after June 15, 2005. Such stock option expensing will require us to value our employee stock option grants pursuant to an option valuation formula and amortize that value against our earnings over the vesting period in effect for those options. We currently account for stock-based awards to employees in accordance with Accounting Principles Board Opinion No. 25,Accounting for Stock Issued to Employees, and have adopted the disclosure-only alternative of SFAS No. 123,Accounting for Stock-Based Compensation. When we are required to expense employee stock options in the future, this change in accounting treatment could materially and adversely affect our reported results of operations as the stock-based compensation expense would be charged directly against our reported earnings. For pro forma disclosure illustrating the effect such a change on our recent results of operations, see Note 1 of the Consolidated Financial Statements.

Legislative actions, higher insurance costs and potential new accounting pronouncements may affect our future financial position and results of operations.

      To comply with the Sarbanes-Oxley Act of 2002, as well as recent changes to Nasdaq listing standards, we have been and will be required to hire additional personnel and utilize additional outside legal, accounting and advisory services, all of which will cause our general and administrative costs to increase. Insurers may increase premiums as a result of high claims rates experienced by them over the past year, and so our premiums for our various insurance policies, including our directors’ and officers’ insurance policies, could be subject to increase. Proposed changes in the accounting rules, including legislative and other proposals to account for employee stock options as a compensation expense among others, could materially increase the expenses that we report under generally accepted accounting principles and adversely affect our operating results.

Item 4. Information on the Company

A.      History and Development of the Company

About the Company

      We are an Irish resident public limited company (company number 171387) and operate under Irish company law. We were incorporated in Ireland on March 19, 1991 under the legal and commercial name IONA Technologies Limited and re-registered under the legal and commercial name IONA Technologies PLC in February 1997. Our registered office and principal place of business is The IONA Building, Shelbourne Road, Ballsbridge, Dublin 4, Ireland. Our telephone number at that location is +353 1 6372000.

      The principal place of business in the United States of our wholly-owned subsidiary, IONA Technologies, Inc., is 200 West Street, Waltham, MA, 02451, USA.

Important Company Events and Company Takeovers

      In 2001, we acquired Netfish Technologies, Inc. (Netfish). The total consideration consisted of 4,221,216 newly-issued ordinary shares, 815,102 ordinary shares issuable upon the exercise of replacement options and $30.9 million of closing costs incurred in connection with the merger. Of the newly-issued ordinary shares, 504,598 were held back by us as a source of indemnification payments that may become due to us. If we made no claims for indemnification, 75% of the 504,598 ordinary shares, or 378,448 shares, would have been distributed to the former holders of Netfish shares in May 2002 and 25% of the 504,598 ordinary shares, or 126,150 shares, would have been distributed in May 2003. In May 2002, we held back 142,045 ordinary shares to cover indemnification claims made by us. In May 2003, an additional 126,150 ordinary shares were held back to cover the indemnification claims that we previously made. If pending indemnification claims are resolved in a manner unfavorable to us, up to 268,195 ordinary shares held back by us could be distributed to the former holders of Netfish shares.

Certain Investments

      During 2004, 2003 and 2002 we invested $1.1 million, $1.2 million and $5.2 million, respectively, for the purchase of property and equipment, for further investment in our management information systems and for capital expenditures.

      During 2004, 2003 and 2002 we invested $0.2 million, $0.1 million and $0.2 million, respectively, in technology, which had reached technological feasibility. In addition, our research and development expenditures in 2004, 2003 and 2002 were approximately $17.2 million, $27.1 million and $38.3 million, respectively.

B.      Business Overview

Overview

      IONA is in the integration software business. We make software work together so our customers can make better decisions, run their businesses more efficiently and improve their business results. Our software products enable our customers to build, maintain and scale their disparate computing environments while preserving and extending existing information technology (IT) investments. We also offer professional services, including ongoing customer support and maintenance as well as high-level design consultation, education and product implementation.

      IONA was founded in 1991 in Dublin, Ireland. We have a history of providing standards-based solutions to IT organizations with complex, heterogeneous computing environments and challenging integration problems. We have a proven record of technology leadership and continuous product improvement.

-12-

      We generate revenue from product licenses as well as from professional services. Since our inception, we have licensed our products, directly and indirectly, to more than 4,500 enterprise or divisional customers worldwide. On December 31, 2004, we employed more than 340 people in 16 offices worldwide.

Industry Background

      Large organizations have spent the last several decades investing in IT, seeking improved productivity and agility through business process automation. As they have invested in computing assets over time, few organizations have addressed how to make their various computing investments work well together or considered the architectural and technology choices that would make it easier to retire or replace assets. As a result, these organizations have a mix of applications and infrastructure technologies based on different programming languages, running on different operating systems on different hardware platforms and managed and mediated by various middleware technologies. Some of these systems are off-the-shelf applications acquired from commercial software vendors. Other systems are the product of in-house custom development. Many of the most critical systems remain in use long after their underlying technologies are succeeded by newer technologies.

      For organizations with particularly large and complex IT environments, this mix of applications and technologies impedes innovation and competitive initiatives. For example, telecommunication providers retain existing customers and attract new customers largely on their abilities to respond efficiently to market changes, to innovate around product offers and product bundles, to empower customers with self-service opportunities, and to provide responsive and effective customer service. All of these initiatives are, at their core, driven by IT. If a telecommunications provider is unable to respond to its competitors’ offerings because its own IT systems cannot be made to work together, the complexity and diversity of those IT systems is a liability.

      Integration of IT systems persists as an issue of critical importance to large organizations. Since the early 1990s, IONA has built its integration products around two very significant open industry standards, initially CORBA and more recently Web services, and a unifying approach to designing and implementing large-scale systems referred to as service-oriented architecture, or SOA.

     CORBA. CORBA promised to make applications interoperable by exposing them as platform neutral services with interfaces based on a consensual standard. CORBA proved to be very popular for building and integrating systems where high performance, high transaction volumes, and high scalability were required, and for organizations with a long-term strategy for computing asset reuse and ongoing interoperability. For example, many of the world’s telephone network management systems are built on, and interoperate using, CORBA. A telephone call traverses numerous telephone network systems, interacting at extremely high speed with a number of billing applications, switches, and other systems, all integrated with CORBA.

     Web services. A growing number of organizations are now evaluating Web services technologies for their suitability as an integration solution. Descended from the World Wide Web, the most successful experiment in interoperability, Web services emanate from a collection of industry standards that specify how computer systems, or parts of systems, can be represented as business services. These standards also describe how data and transactions can be exchanged between computer systems, and how services can be discovered and identified.

      Web services hold the potential for giving computer systems ease of interaction by leveraging these worldwide standards for use in enterprise IT. As a result, large organizations, and integration solution vendors, are eager to exploit the potential of the Web services standards. Despite the relative immaturity of these standards, Web services allow applications to more easily interoperate and share data. Web services facilitate the implementation and management of dynamic business applications and systems in a less disruptive, less costly and faster manner than in existing integration solutions. Web services also allow organizations to broadly service-enable their IT assets in a systematic fashion.

-13-

     Service-oriented Architecture. SOA describes a technology-independent approach to building applications that focuses particularly on system integration and reuse of existing business computing functionality. SOAs encourage application developers to take a business-focused approach to building systems which ensures that IT organizations and line-of-business organizations have a common frame of reference.

      CORBA and Web services are naturally suited to SOAs. CORBA is the core technology supporting a number of very large SOA implementations. The architectural impact of Web services, coupled with their broad accessibility, makes Web services intriguing to organizations using SOAs. These organizations tend to be large and sophisticated and demand enterprise-wide integration solutions. For organizations focused on using SOAs, simple interoperability is not enough. Integration projects require additional, sophisticated security, availability, reliability and management capabilities, among others. CORBA and Web services standards address many of these advanced requirements.

IONA’s Opportunity

      Our opportunity is to provide standards-based solutions to organizations wanting to use Web services, CORBA and other technologies to solve enterprise integration problems or to develop and deliver SOAs.

      We are a leader in Web services technology, with a history of delivering award-winning Web services-based integration products. We are also influential in the evolution of the Web services standards and how they relate to the delivery of enterprise integration capabilities. We also have a history of promoting SOAs. Our focus on SOAs is one of our core competencies. As more organizations deploy SOAs, we are well positioned to explain and deliver the benefits of an architectural approach to integration.

      We have a history of promoting large-scale, standards-based integration solutions for our customers. Our standards-based solutions allow our customers across a wide variety of industries to develop and deploy integration projects involving hundreds of systems, and tens of thousands of users.

      We have had an uncompromising commitment to industry standards since their inception. Our early support for CORBA was augmented by solutions built on later-evolving standards such as J2EE, XML and Web services. We are actively involved in industry organizations and standards-setting bodies, particularly the Object Management Group, World Wide Web Consortium, the Organization for the Advancement of Structured Information Standards (OASIS), the TeleManagement Forum, the Parlay Group and the Web Services Interoperability Organization. IONA is a member of the Executive Committee of the Java Community Process (JCP) Program 2.0, an open community-based process to further develop and revise Java technology specifications.

      Our deep commitment to industry standards mitigates our customers’ risk of being locked into a proprietary solution from a single vendor. Therefore, our standards-based solutions provide our customers a lower total cost of ownership of software, developer training, implementation services, and ongoing support.

      Similarly, our demonstrated SOA expertise facilitates the connection of our customers’ IT assets to a common backbone which empowers these organizations to leverage and reuse their existing assets. The best SOAs are based on standards, which insulate the customer’s integration investments from future changes in technology, products, selling channels and business processes. As other integration vendors announce their product visions around Web services and SOAs, our solutions are already helping customers solve enterprise integration challenges with these technologies.

Strategy

      Our objective is to be the leading provider of standards-based enterprise integration solutions. To achieve this objective, we intend to continue to pursue the following:

•  Maintain Technological Leadership. We have a history of technological leadership and dedication to continuous product improvement. Our CORBA-based Orbix product family is the leading enterprise CORBA solution. Our Web services-based Artix product family continues the Orbix

-14-

	tradition by addressing the integration and mobile computing needs of large IT organizations through high performance, standards-based solutions. We will continue to invest heavily in research and development. By promoting and embracing existing and emerging industry standards, we intend to facilitate the broad acceptance of our products. We may acquire businesses, products or technologies that we believe will enhance and expand our current product offerings.
•	Expand Our Customer Base, While Retaining Our Existing Customers. Many of our customers are large companies in a variety of industries that are deeply invested in both our products and our architectural approach to integration. The strategic importance of our products allows us, working with our partners, to develop strong relationships with our customers’ key technology decision makers. In addition, our strategic selling approach facilitates broad adoption of our products throughout a customer’s IT organization. All of these factors combine to represent an opportunity for us to continue to present new generations of technology solutions to our enterprise customers in the telecommunications, government and financial services industries. At the same time, the broader popularity of Web services gives us an opportunity to go outside of our traditional customer base to attract new customers with complex, costly and heterogeneous computing environments. We believe these new customers are interested in the reductions in IT cost and complexity that Web services and SOA can deliver. We also believe these new customers will find our traditional architectural approach, combined with our new generation of Web services integration solutions, compelling and competitive.
•	Leverage and Expand Strategic Alliances. We understand that relationships with leading software and other technology vendors, as well as system integrators, create opportunities to gain customers in broader markets than those otherwise available to us. We are focused on leveraging our established relationships and forging new alliances to enhance our marketing, selling and implementation initiatives. We believe that many of these vendors and system integrators seek to partner with strong infrastructure technology providers that will enable them to more rapidly satisfy customer needs. We have existing relationships with leading software and technology vendors, such as Sun Microsystems, JBoss, Business Objects and Manugistics, and global system integrators, such as BearingPoint and Computer Sciences Corporation (CSC). We believe that these relationships better enable us to sell additional products to our existing customer base, acquire new customers and enhance our market presence.

Products

      We offer two product families, Artix and Orbix. Both products address the enterprise integration needs of our customers using standards-based technology. Orbix is the more mature of the two product families and continues to support critical applications in the telecommunications, financial services and government vertical markets. Artix is an enterprise service bus (ESB) product that provides critical infrastructure for enterprise integration based on a SOA. Both product families allow our customers to reduce the cost and complexity of their enterprise IT environment and to extend the life and value of their IT investments.

     Artix

      Artix is our extensible enterprise service bus (ESB) product family. Artix is Web services-based integration software for enterprise IT organizations with multiple generations of business applications, technologies and architectures. Artix makes these IT assets work together, forming the basis for an agile SOA.

      Artix is designed for organizations with complex and heterogeneous computing environments. These organizations use Artix to represent IT assets as Web services, making it easy to integrate these assets or to consolidate assets without disrupting operations.

      Artix makes Web services immediately useful in an enterprise context. For example, Artix empowers organizations to incorporate the proven enterprise features of their existing computing environments to add

-15-

security, reliability, availability and management features to Web services. Artix lets organizations reuse existing middleware and application functionality to create secure, manageable Web services integration projects.

      Artix is available on a wide range of hardware and software platforms including many variants of Unix as well as Microsoft platforms. IONA also offers a mainframe-based version of Artix that gives organizations the ability to Web service enable IBM’s Information Management Service, or IMS, and Customer Information Control System, or CICS, applications. IMS and CICS support large-scale, transaction-intensive mainframe applications. Organizations with large investments in CICS and IMS are committed to the ongoing use of their mainframes, and need a secure means of reusing and extending the life of those investments.

     Orbix

      Orbix is our original high performance infrastructure for mission-critical applications. Orbix is a comprehensive and proven platform for extending or integrating the most demanding component-based systems. Orbix encourages a services-oriented approach to component development and integration, with immediate benefits to productivity, efficiency and operational expense.

      Orbix is engineered to support the integration of CORBA with other technologies, especially J2EE and Web services. Orbix has been used to encourage the reuse of legacy systems by replacing their proprietary application interfaces with standards-based interfaces; to build new, service-oriented systems in Java or C++; to extend the value of mainframe assets by exposing them as services; and to non-intrusively augment existing systems with new functionality. Our Orbix offering is augmented by a second similar CORBA solution, Orbacus, which is available in source code form for those customers preferring a source-available product.

      Like Artix, Orbix meets the needs of enterprise IT organizations by providing a set of enterprise qualities of service for security, asynchronous messaging, management, transactions, load balancing, and fault tolerance.

Services

      We provide a variety of support and consulting services to our customers. Our professional services personnel provide our customers, partners and internal field organizations with educational services, as well as product and architectural consulting services. These personnel are senior technologists, with substantial expertise in leading integration and development technologies, including CORBA, J2EE and XML. Our customer support personnel are dedicated to the ongoing support and maintenance of our products. In addition to telephone-based and on-site product support, we also provide customers with a self-help support option in the form of a comprehensive online database of technical information and advice.

      Our customers are encouraged to purchase annualized customer support agreements. Most product support is provided through a combination of telephone and e-mail support from our Dublin, Ireland headquarters and our U.S. subsidiary’s office in Waltham, Massachusetts. Our original equipment manufacturers, value-added resellers and independent software vendors depend on our customer service team to provide backup for the front-line support that these vendors provide to their customers.

      As of December 31, 2004, our services organization comprised 53 employees.

Product Development and Management

      Our technology and products have traditionally been the result of internal development by our engineers and strategic acquisitions. Product development and management is concentrated primarily in our Dublin, Ireland headquarters and our U.S. subsidiary’s offices in Waltham, Massachusetts. Our product management organization collaborates with our marketing and sales organizations to increase sales of products and to develop customer and indirect sales relationships.

-16-

      As of December 31, 2004, we had 131 employees dedicated to research and development. Our research and development expenditures in 2004, 2003, and 2002 were approximately $17.2 million, $27.1 million, and $38.3 million, representing 25.3%, 36.6%, and 31.0% of total revenue in 2004, 2003, and 2002, respectively. We expect to continue investing significant resources in research and development in the future.

Customers

      Since our inception, we have licensed, directly or indirectly, our products to more than 4,500 enterprise or divisional customers worldwide. These customers operate in a wide variety of industries including telecommunications, finance, manufacturing, banking, government, medical, computing, research and software. The following is a selected list of customers across some of our targeted industries:

Financial	Telecom	Government
Credit Suisse Group	BellSouth	Department of Homeland Security
JPMorgan Chase	SBC	National Geospatial-Intelligence Agency
Lehman Brothers	AT&T	U.S. Dept. of Transportation
Winterthur Insurance	Nokia	N.A.S.A.
Reuters	Marconi Sprint	U.S. Environmental Protection Agency

      No customer accounted for more than ten percent of our total revenue in 2004, 2003, or 2002.

      We derive a significant amount of our total revenue from customers located outside the United States. Revenue from customers located outside the United States was approximately 48.7%, 48.3%, and 38.8% of total revenue for 2004, 2003, and 2002, respectively. We expect revenue from customers located outside the United States to continue to represent a significant percentage of our total revenue for the foreseeable future.

Sales and Marketing

      We market our products and services through our marketing and direct sales organizations and through indirect channels including software vendors, system integrators, original equipment manufacturers, and value-added resellers. As of December 31, 2004, our sales and marketing organization consisted of 110 professionals.

      Our direct sales force consists of account managers and field and inside sales personnel, complemented by technical pre-sales and high-level product specialists who are available for customer visits. Our sales force and executive team maintain relationships with customers’ senior management for large-scale projects. Our sales force also maintains contact at the developer level to understand and serve the developer’s requirements.

      Our sales organization is divided into three geographical regions: the Americas, Asia-Pacific and Europe/ Middle East/ Africa. In addition, we dedicate members of our sales force to developing strategic relationships with our indirect channel partners.

      Our indirect distribution channels include leading software vendors, such as Business Objects and Manugistics; global system integrators, such as BearingPoint and CSC; leading original equipment manufacturers, such as Sun Microsystems, Intel and CISCO; and resellers and distributors. We believe that relationships with leading software and other technology vendors, as well as system integrators, provide opportunities to gain customers in markets where our products and services are in demand.

      Our marketing teams execute global marketing programs designed to create demand for our products and services. We rely on a variety of marketing programs for demand creation, including trade shows, limited duration evaluation software, direct marketing communications, Web casts, public relations, product literature and collateral, trade advertising, and a corporate Web site.

-17-

Competition

      Our sector of the software industry is very dynamic and very competitive. The growing industry enthusiasm for Web services and ESB products has increased competition levels as consumers begin to appreciate the potential value of Web services and Web services technology providers.

      We compete with a variety of software vendors, including established providers of broad infrastructure platforms, new and narrowly focused software companies, and even shareware and freeware providers. In some cases, these vendors’ offerings are narrowly defined and compete with our products in a limited set of features or problems. Other vendors target roughly the same range of IT problems as we do. Still others have broad infrastructural offerings that compete with our products in specific scenarios.

      We compete against:

• Enterprise application infrastructure providers;

• Enterprise application integration software vendors;

• Web services integration companies;

• Enterprise service bus (ESB) vendors;

• open source software projects and products.

      We believe that the principal competitive factors that affect the market for our products include:

• Potential customers’ perception of our market leadership in a demanding and fast-moving technology environment;

• Our continued conformity to industry standards, and customers’ ongoing preference for standards-based products;

• Breadth of product offerings;

• Product features and functionality;

• Product ease-of-adoption and ease-of-use;

• Product quality;

• Our customer service and support;

• Security, reliability, availability and other enterprise qualities of service;

• Product and service pricing; and

• Our reputation and financial viability.

Patents and Proprietary Technology

      We regard much of our intellectual property as proprietary to us and rely primarily on a combination of copyright, trademark, patent and trade secret laws, employee and third-party non-disclosure agreements and technical measures to establish and protect our proprietary rights. We own numerous registered trademarks and trademark applications pending in the United States, the European Union, Australia and Asia, as well as other jurisdictions throughout the world.

      While we generally use negotiated, signed license agreements or shrink-wrap type licenses to restrict copying and use of our software products, we do not generally embed mechanisms in our software to prevent unauthorized use or copying of our software. We do not rely significantly on patents or other registered intellectual property rights to protect our software. We also have a number of U.S. and international patent and trademark applications pending. Because shrink-wrap type licenses are not signed by licensees, they may be unenforceable under the laws of certain jurisdictions. In addition, the laws of

-18-

various countries in which our products may be sold may not protect proprietary rights to the same extent as the laws of the United States and Ireland.

      We license from time to time technologies and products from third parties for incorporation in our products.

      We generally enter into confidentiality agreements with our employees and consultants, and limit access to, and distribution of, our proprietary information to customers and potential customers.

Employees

      As of December 31, 2004, we had 346 full-time employees, with 154 based in the Americas, 153 based in Europe/ Middle East/ Africa and 39 based in Asia-Pacific. These employees include 131 in product development and management, 53 in services, 17 in marketing, 93 in sales and 52 in finance and administration. Our employees are not represented by any collective bargaining organizations, and we have not experienced any work stoppages. Our relations with our employees are good.

Legal Proceedings

      We are not a party to any legal proceedings that, if resolved or determined adversely to us, would have a material adverse effect on our business, financial condition and results of operations. We, however, are subject to claims and litigation in the ordinary course of business. In the event that any such claims or litigation are material and resolved against us, such outcomes or resolutions could have a material adverse effect on our business, financial condition or results of operations.

Government Regulations

      We have significant operations and generate a substantial portion of our taxable income in Ireland. In general, the tax rate in Ireland on trading income, which is 12.5% with effect from January 1, 2003, is significantly lower than U.S. tax rates. Moreover, our Irish taxable income derived from software substantially developed in Ireland is taxed at a 10% effective tax rate. Therefore, our effective tax rate is affected by the percentage of revenue that qualifies for this favorable tax treatment. We anticipate that we will continue to benefit from this tax treatment, although the extent of the benefit could vary from period to period, and our tax treatment may change in the future. Any variation in the amount of our benefit from this tax treatment could have a material adverse effect on our business, financial condition and results of operations.

      For more information regarding the impact of tax regimes on our business, please see Item 3.D. “Risk Factors—If our effective tax rate increases, our business and financial results would be adversely impacted” and Item 10.E. “Taxation.”

Principal Markets

      For a description of the principal markets in which we compete, including a breakdown of total revenues by category of activity and geographic market for each of the last three financial years, see Item 5 “Operating and Financial Review and Prospects.”

Seasonality and Raw Materials

      Historically, our product revenue in the first quarter of each year has declined from the fourth quarter of the prior year. Our products and services do not materially depend on the availability of raw materials.

C. Organizational Structure

      IONA Technologies PLC has 23 direct and indirect subsidiaries, of which three are significant—IONA Technologies, Inc. (IONA U.S.), incorporated in Delaware, IONA Technologies Japan, LTD (IONA Japan), incorporated in Japan and IONA Technologies Finance (IONA Finance),

-19-

incorporated in the Cayman Islands. IONA U.S., IONA Japan, and IONA Finance are wholly-owned by IONA Technologies PLC.

D. Property and Equipment

      Our headquarters are currently located in a leased facility in Dublin, Ireland. This facility consists of approximately 55,900 square feet of office space, under a lease expiring on July 31, 2023, subject to our right to terminate the lease on July 31, 2013. As of December 31, 2004, we occupied 17,600 square feet of the office space and sublet approximately 22,880 square feet with the remainder deemed idle. The principal U.S. office of IONA U.S. is located in a leased facility in Waltham, Massachusetts. This facility consists of approximately 65,480 square feet of office space, under a lease expiring in 2006, subject to our right to renew for an additional term of five years expiring in 2011. As of December 31, 2004, we occupied approximately 30,359 square feet and sublet approximately 35,121 square feet. The principal office of IONA Japan is located in a leased facility in Tokyo, Japan. In addition, our wholly-owned subsidiaries maintain offices in Colorado, California, Illinois, Virginia, Texas, Newfoundland, Frankfurt, Munich, Milan, Paris, London, Zurich, Beijing and Shanghai. We believe that these facilities are adequate for our present operations and that additional facilities to support our present and future operations are available on commercially reasonable terms. We do not expect in the near future to move to new, or expand into additional, facilities. However, in the event of any such move or expansion there could be a material adverse effect on our business, financial condition and results of operations or a disruption in the development or marketing of products. For more information, please see Item 3.D. “Risk Factors.”

Item 5. Operating and Financial Review and Prospects

     The following discussion and analysis of financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements for the periods specified and associated notes included in Item 3.A. “Selected Financial Data.” The following discussion and analysis of financial condition and results of operations contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 that relate to future events or our future financial performance. In some cases, you can identify forward-looking statements by terminology, such as “may,” “will,” “should,” “could,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “predict,” “intend,” “potential,” or “continue” or the negative of such terms or other comparable terminology, although not all forward-looking statements contain such terms. In addition, these forward-looking statements include, but are not limited to, statements regarding, among other things, our plans, objectives, expectations and intentions. These forward-looking statements are neither promises nor guarantees but rather are subject to a number of risks and uncertainties which could cause actual results to differ materially from those described in the forward-looking statements, including risks and uncertainties relating to IONA’s cost reduction efforts; the launch of IONA’s integration software; growth in market demand for Web services and integration; IONA’s sales model; volume, timing and seasonal patterns of product sales; impact of competitive products and pricing; development, launch and market acceptance of new and improved products; the integration of any future acquisitions; undetected errors in software; and general economic conditions, including their effect on the acquisition of new accounts and the time required to close sales transactions. Further reference should be made to Item 3.D. “Risk Factors.”

A. Operating Results

Overview

      IONA is in the integration software business. We make software work together so our customers can make better decisions, run their businesses more efficiently and improve their business results. Our software products enable our customers to build, maintain and scale their disparate computing environments while preserving and extending existing information technology (IT) investments. We also offer professional services, including ongoing customer support and maintenance as well as high-level design consultation, education and product implementation.

      Our revenue is derived from product license fees and charges for support and professional services. We recognize revenues in accordance with the provisions of the American Institute of Certified Public Accountants Statement of Position (SOP) 97-2, “Software Revenue Recognition,” as amended by SOP 98-4 and SOP 98-9 and related interpretations (collectively, SOP 97-2). In accordance with U.S. GAAP, we recognize software license revenue when persuasive evidence of an arrangement exists, delivery has occurred, our fee is fixed or determinable, and collectibility is probable. We recognize customer support revenue over the term of the support agreement, generally 12 months. We recognize professional service revenue when the services are performed.

      Our customers are corporate IT departments of large organizations with complex, heterogeneous computing environments and challenging integration problems. Our customers operate worldwide in a variety of industries including telecommunications, finance, manufacturing, banking, government, medical, computing, research and software. No single customer accounted for more than 10% of total revenue in 2004, 2003, or 2002.

      To date, we have derived most of our revenue from the licensing of our enterprise integration software products that currently comprise our Orbix products, and fees from related services. We expect that Artix will increasingly contribute to our revenue. We market our products and services through our direct marketing and sales organizations and through indirect channels, including software vendors, system integrators, original equipment manufacturers, value-added resellers and, to a lesser extent, third-party distributors. Our total revenue is dependent on the growth in demand for our software. In general, product revenue in the first quarter of each year declines from the fourth quarter of the prior year in line with traditional seasonal trends.

-21-

      Our total revenue was approximately $68.0 million in 2004, $74.2 million in 2003 and $123.2 million in 2002. Total revenue from customers located outside the United States was approximately $33.2 million, or 48.7% of total revenue, in 2004, $35.9 million, or 48.3% of total revenue, in 2003 and $47.8 million, or 38.8% of total revenue, in 2002. As a percentage of total revenue, product revenue was approximately 45.2% in 2004, 48.2% in 2003 and 59.6% in 2002.

      Our gross margins are affected by the mix of product and service revenue and the mix of distribution channels used by us. We typically realize significantly higher gross margins on product revenue than on service revenue. Product gross margins as a percentage of product revenue were approximately 99.2%, 98.5% and 97.7% in 2004, 2003 and 2002, respectively. Service gross margins as a percentage of service revenue were approximately 68.4%, 62.9% and 48.9% in 2004, 2003 and 2002, respectively. The increase in service gross margin from 2003 to 2004, and from 2002 to 2003 was primarily attributable to a reduction in service personnel, as a result of our restructuring plans, coupled with higher utilization rates.

      We have significant operations and generate a substantial portion of our taxable income in Ireland. In general the tax rate in Ireland on trading income, which is 12.5% with effect from January 1, 2003, is significantly lower than U.S. tax rates. Moreover, our Irish taxable income derived from software substantially developed in Ireland is taxed at a 10% effective tax rate. Therefore, our effective tax rate is affected by the percentage of revenue that qualifies for such favorable tax treatment. We anticipate that we will continue to benefit from this tax treatment, although the extent of the benefit could vary from period to period, and our tax treatment may change in the future.

Impact of Acquisitions

      In 2001, we acquired Netfish Technologies, Inc. (Netfish). The total consideration consisted of 4,221,216 newly-issued ordinary shares, 815,102 ordinary shares issuable upon the exercise of replacement options and $30.9 million of closing costs incurred in connection with the merger. Of the newly-issued ordinary shares, 504,598 were held back by us as a source of indemnification payments that may become due to us. If we made no claims for indemnification, 75% of the 504,598 ordinary shares, or 378,448 shares, would have been distributed to the former holders of Netfish shares in May 2002 and 25% of the 504,598 ordinary shares, or 126,150 shares, would have been distributed in May 2003. In May 2002, we held back 142,045 ordinary shares to cover indemnification claims made by us. In May 2003, an additional 126,150 ordinary shares were held back to cover the indemnification claims that we previously made. If pending indemnification claims are resolved in a manner unfavorable to us, up to 268,195 ordinary shares held back by us could be distributed to the former holders of Netfish shares.

      In 2001, we acquired Object-Oriented Concepts, Inc. (OOC). The total consideration consisted of $3.0 million in cash, 730,453 newly-issued ordinary shares and 178,131 ordinary shares issuable upon the exercise of replacement options. Of the newly-issued ordinary shares, 262,129 were subject to return to us as a purchase price adjustment upon the failure of OOC to achieve certain performance targets. In 2001, 174,735 ordinary shares no longer subject to return were recorded as additional purchase price based on fair market value at the time the performance targets were achieved. In 2002, the remaining 87,394 ordinary shares were no longer subject to return to us and were recorded as additional purchase price. The aggregate purchase price plus related expenses have been allocated to the acquired assets and liabilities at their estimated fair values at the date of the acquisition based primarily on an independent valuation.

      In 2001, we obtained from Software AG, Inc. a non-exclusive license to Sagavista application integration software for $10.0 million.

      In accordance with Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (SFAS 142), in October 2002, we completed our assessment of the carrying value of purchased technologies and completed the relevant impairment tests as required by Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (SFAS 144). Due to unfavorable market conditions and changes in our product strategy, it was determined that the carrying values of purchased technologies exceeded their fair value resulting in the recording of a non-cash impairment charge of $28,586,000.

-22-

      Our assessment included an independent analysis of the carrying values of purchased technologies, recorded in connection with the acquisitions of OOC, Netfish and the Sagavista application integration software of Software AG, including an initial comparison of the carrying value for each purchased technology to the future undiscounted cash flows associated with the technology. As a result of this analysis, it was determined due to the excess carrying value associated with each purchased technology that further impairment testing was required. We recorded non-cash impairment losses in October 2002, for the purchased technologies recorded in connection with the acquisitions of OOC, Netfish, and the Sagavista application integration software of Software AG of approximately $4,461,000, $11,496,000 and $6,250,000, respectively. These impairment losses (reflected in the Consolidated Statement of Operations as impairment of intangible assets and fixed assets) represent the amount by which the carrying value of each purchased technology exceeded its estimated fair value, calculated by discounting future cash flows for each purchased technology to a present value using a rate of return which reflected the relative risk of the investment and the time value of money. In addition in 2002, as a result of changes in product strategy, in reaction to market conditions, which resulted in changes to our product suite and the elimination of certain other purchased technologies from our product suite, an impairment loss of approximately $6,379,000 was recorded, equivalent to the carrying values of these purchased technologies.

      In October 2004, we received $600,000 from our insurers in connection with the favorable resolution of an acquisition contingency, relating to litigation costs, which resulted in the recognition of $600,000 of income.

Critical Accounting Policies and Estimates

      Our Consolidated Financial Statements are prepared in accordance with United States generally accepted accounting principles (U.S. GAAP). These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions upon which we rely are reasonable based upon information available to us at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the Consolidated Financial Statements, as well as the reported amounts of revenues and expenses during the periods presented. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The significant accounting policies that we believe are the most critical to aid in fully understanding and evaluating our reported financial results include the following:

• Revenue Recognition;

• Restructuring Charge;

• Allowances for Doubtful Accounts;

• Legal Contingencies;

• Accounting for Income Taxes;

• Impairment of Other Non-Current Assets; and

• Foreign Currency.

      In many cases, the accounting treatment of a particular transaction is specifically dictated by U.S. GAAP and does not require management’s judgment in its application. There are also areas in which management’s judgment in selecting among available alternatives would not produce a materially different result. Our senior management has reviewed these critical accounting policies and related disclosures with our Audit Committee. See Notes to the Consolidated Financial Statements, which contain additional information regarding our accounting policies and other disclosures required by U.S. GAAP.

-23-

Revenue Recognition

      We recognize the majority of our revenue pursuant to software license agreements. While the basis for software license revenue recognition is substantially governed by the provisions of SOP 97-2, “Software Revenue Recognition,” as amended by SOP 98-4 and SOP 98-9 and related interpretations issued by the American Institute of Certified Public Accountants (collectively, SOP 97-2), we exercise judgment and use estimates in connection with the determination of the amount of software license and services revenues to be recognized in each accounting period.

      For software license arrangements that do not require significant modification or customization of the underlying software, we recognize revenue when: (1) we enter into a legally binding arrangement with a customer for the license of software; (2) we deliver the products or perform the services; (3) customer payment is deemed fixed or determinable and free of contingencies or significant uncertainties; and (4) collection is probable. Substantially all of our license revenues are recognized in this manner.

      For arrangements with multiple elements, we allocate revenue to each element of a transaction based upon its fair value as determined by “vendor specific objective evidence.” Vendor specific objective evidence of fair value for each element of an arrangement is based upon the normal pricing and discounting practices for each element when sold separately, including the renewal rate for support services. If we cannot objectively determine the fair value of any undelivered element included in the multiple element arrangement, we defer revenue until all elements are delivered, services have been performed, or until fair value can be objectively determined. When the fair value of a delivered element cannot be established, we use the residual method to record license revenue, provided the fair value of all undelivered elements is determinable. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is allocated to the delivered elements and is recognized as revenue.

      We assess whether fees are fixed or determinable at the time of sale and recognize revenue if all other revenue recognition requirements are met. Our standard payment terms are net 30; payment terms, however, may vary based on the country in which the agreement is executed. Payments that extend beyond 30 days from the contract date but that are due within twelve months are generally deemed to be fixed or determinable based on our successful collection history on such arrangements, and thereby satisfy the required criteria for revenue recognition.

      We assess whether collection is probable at the time of the transaction based on a number of factors, including the customer’s past transaction history and credit-worthiness. If we determine that the collection of the fee is not probable, we defer the fee and recognize revenue at the time collection becomes probable, which is generally upon the receipt of cash.

      We generally deliver products F.O.B shipping or electronically, and our software arrangements typically do not contain acceptance provisions. Accordingly, delivery is usually satisfied when the product leaves our premises, or if shipped electronically, when the customer has been provided with access codes to allow them to take immediate possession of the software.

      Revenue for consulting services is generally recognized on a time and material basis. Revenue from royalty arrangements in excess of guaranteed amounts is recognized upon notification of such royalties payable by the customer.

Restructuring Charge

      During 2004, 2003, and 2002, we recorded restructuring charges to align our cost structure with changing market conditions. Our restructuring plan resulted in a reduction in headcount and the closure and consolidation of excess facilities. In determining the charges to record, we made certain estimates and judgments surrounding the amounts ultimately to be paid for the actions we have taken. At December 31, 2004, there were various accruals recorded for the costs to terminate employees and exit certain facilities and lease obligations, which may be adjusted periodically for either resolution of certain contractual commitments or changes in estimates of severance payments, sublease income or the period of time the

-24-

facilities will be vacant and subleased. During 2004, we reached final settlement with several employees that had been included in the 2003 restructuring charge. The settlements resulted in a credit to the 2004 restructuring charge of $560,000. Although we do not anticipate additional significant changes to our restructuring accruals, the actual costs may differ from those recorded in the event that the subleasing assumptions require adjustment due to changes in economic conditions surrounding the real estate market or we terminate our lease obligations prior to the scheduled termination dates.

      In order to estimate the costs related to our restructuring efforts, management made its best estimates of the most likely expected outcomes of the significant actions to accomplish the restructuring. These estimates principally related to charges for excess facilities and included estimates of future sublease income, future net operating expenses of the facilities, brokerage commissions and other expenses. The operating lease charges were calculated by taking into consideration (1) the committed annual rental charge associated with the vacant square footage, (2) an assessment of the sublet rents that could be achieved based on current market conditions, vacancy rates and future outlook following consultation with third party realtors, (3) an assessment of the period of time the facility would remain vacant before being sub-let, (4) an assessment of the percentage increases in the primary lease rent at each review, and (5) the application of a discount rate of 4% over the remaining period of the lease or break clause.

      These estimates are reviewed at the end of each period and would be revised if estimated future vacancy rates and sublease rates vary from our original estimates. Historically, our estimates and assumptions used to determine the liability for excess facilities have been consistent with actual results experienced. Revisions to our estimates of this liability could materially impact our operating results and financial position in future periods if anticipated events and assumptions, such as the timing and amounts of sublease rental income, either change or do not materialize.

Allowances for Doubtful Accounts

      We maintain allowances for doubtful accounts, as a reduction of accounts receivable, based on our analyses of the likelihood our customers will not pay us all the amounts due us. In circumstances where there is knowledge of a specific customer’s inability to meet its financial obligations, a specific reserve is recorded against amounts due to reduce the net recognized receivable to the amount that is reasonably believed to be collectable. For all our customers we perform analyses, which includes a review of their credit profiles, the terms and conditions of the contracts with our customers, and the current economic trends and payment history. We reassess these allowances each accounting period. Historically, our actual losses and credits have been consistent with these provisions. If actual payment experience with our customers is different than our estimates, adjustments to these allowances may be necessary resulting in additional charges to our Consolidated Statement of Operations.

Legal Contingencies

      We are involved in various claims and legal proceedings. Periodically, we review the status of each significant matter and assess our potential financial exposure, in consultation with external counsel, based on the facts and circumstances available to us and the probability of potential loss arising from the claim. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, we accrue a liability for the estimated loss. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to our pending claims and litigation and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material impact on our consolidated results of operations, financial position or cash flows.

Accounting for Income Taxes

      Significant judgment is required in determining our worldwide income tax expense provision. In the ordinary course of a global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of income sharing and cost

-25-

reimbursement arrangements among related entities, the process of identifying items of income and expense that qualify for preferential tax treatment and segregation of foreign and domestic income and expense to avoid double taxation. Although we believe that our estimates are reasonable, no assurance can be given that the final tax outcome of these matters will not be different than that which is reflected in our historical income tax provisions and accruals. Such differences could have a material effect on our income tax provision and net income (loss) in the period in which such determination is made.

      Deferred tax assets and liabilities are determined using enacted tax rates for the effects of net operating losses and temporary differences between the book and tax bases of assets and liabilities. We record a valuation allowance to reduce our deferred tax assets by the amount of tax benefits we estimate are not expected to be realized. Tax benefits will not be realized if we do not generate sufficient taxable income in the future to apply against the deferred tax balance. As of December 31, 2004, a valuation allowance equal to the value of the deferred tax assets was maintained. In the event we determined we could realize our deferred tax assets in the future in excess of its net recorded amount, an adjustment to the deferred tax assets would increase net income (loss) in the period such a determination was made.

      In addition, we operate within multiple taxing jurisdictions and may be subject to audits in these jurisdictions. These audits can involve complex issues that may require an extended period of time for resolution. In management’s opinion, adequate provisions for income taxes have been made.

Impairment of Other Non-Current Assets

      Other Non-Current Assets represents costs of technology acquired from acquisitions which have reached technological feasibility. The costs of technology have been capitalized and are amortized to the Consolidated Statement of Operations over the period during which benefits are expected to accrue, currently estimated between three and four years. We are required to test our non-current assets for impairment whenever events or circumstances indicate that the value of the assets may be impaired. Factors we consider important, which could trigger impairment include:

•  significant underperformance relative to expected historical or projected future operating results;

•  significant changes in the manner of our use of the acquired assets or the strategy for our overall business;

•  significant negative industry or economic trends;

•  significant decline in our stock price for a sustained period; and

•  significant decline in our market capitalization relative to net book value.

      Where events and circumstances are present which indicate that the carrying value may not be recoverable, we will recognize an impairment loss. Such impairment loss is measured by comparing the fair value of the asset with its carrying value. The determination of the value of such intangible assets requires management to make assumptions regarding future business conditions and operating results in order to estimate future cash flows to determine the fair value of the respective assets. If the asset’s carrying value is not recoverable through the related cash flows, the asset is considered to be impaired. The impairment is measured by the difference in the asset’s carrying amount and its fair value, based on the best information available, including market prices or discounted cash flow analysis. If these estimates or the related assumptions change in the future, we could be required to record additional impairment charges.

Foreign Currency

      The U.S. dollar is the functional currency for the Company. A percentage of our revenues, expenses, assets and liabilities are denominated in currencies other than our functional currency. Assets and liabilities denominated in foreign currencies are translated at year end exchange rates while revenues and expenses are translated at rates approximating those ruling at the dates of the related transactions. Resulting gains and losses are included in net income (loss) for the year. Fluctuations in exchange rates

-26-

may have a material adverse effect on our consolidated results of operations, particularly our operating margins, and could also result in exchange gains and losses. We cannot accurately predict the impact of future exchange rate fluctuations on our consolidated results of operations. We have in the past sought to hedge the risks associated with fluctuations in exchange rates of the Irish pound and the euro to the dollar. However, because the majority of our sales and expenses are currently U.S. dollar-based, we no longer enter into foreign currency forward exchange contracts to manage exposure related to transactions denominated in foreign currencies. In the future, we may undertake transactions to hedge the risks associated with fluctuations in exchange rates if the risk from foreign currency exposure increases as a result of a decrease in the percentage of U.S. dollar-based transactions. We had no derivative or hedging transactions in 2004, 2003 or 2002.

Taxation

      We have significant operations and generate a substantial portion of our taxable income in Ireland. In general, the tax rate in Ireland on trading income, which is 12.5% with effect from January 1, 2003, is significantly lower than U.S. tax rates. Moreover, our Irish taxable income derived from software substantially developed in Ireland is taxed at a 10% effective tax rate. Therefore, our effective tax rate is affected by the percentage of revenue that qualifies for such favorable tax treatment. See Item 10.E. “Taxation.” We anticipate that we will continue to benefit from this tax treatment, although the extent of the benefit could vary from period to period, and our tax treatment may change in the future. Any variation in the amount of our benefit from this tax treatment could have a material adverse effect on our business, financial condition and results of operations. See Item 3.D. “Risk Factors—If our effective tax rate increases, our business and financial results would be adversely impacted.”

Recent Accounting Pronouncements

      In December 2004, and as amended in April 2005, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123RShare-Based Payment(SFAS 123R), which replaces SFAS 123 and supersedes APB Opinion No. 25. SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The pro forma disclosures previously permitted under SFAS 123 no longer will be an alternative to financial statement recognition. SFAS 123R is effective for fiscal years beginning after June 15, 2005. Early application of SFAS 123R is encouraged, but not required. We plan to adopt SFAS 123R on January 1, 2006.

      Public companies are required to adopt the new standard using a modified prospective method and may elect to restate prior periods using the modified retrospective method. Under the modified prospective method, companies are required to record compensation cost for new and modified awards over the related vesting period of such awards prospectively and record compensation cost prospectively for the unvested portion, at the date of adoption, of previously issued and outstanding awards over the remaining vesting period of such awards. No change to prior periods presented is permitted under the modified prospective method. Under the modified retrospective method, companies record compensation costs for prior periods retroactively through restatement of such periods using the exact pro forma amounts disclosed in the companies’ footnotes. Also, in the period of adoption and after, companies record compensation cost based on the modified prospective method. We have not yet determined the method of adoption we will use. We have not completed our evaluation of the effects of adopting SFAS 123R.

Year Ended December 31, 2004 Compared to Year Ended December 31, 2003

Total Revenue

      Total revenue decreased by 8.3% to $68.0 million in 2004 from $74.2 million in 2003. Total revenue from customers located outside of the United States represented 48.7% of total revenue in 2004 and 48.3% of total revenue in 2003, or $33.2 million and $35.9 million, respectively. The total number of revenue transactions over $250,000 decreased from 62 in 2003 to 55 in 2004. There was an increase in average deal size from approximately $51,000 in 2003 to $53,000 in 2004. No customer accounted for more than 10% of our total revenues in 2004 or 2003.

     Product Revenue. Product revenue decreased by 14.0% to $30.7 million in 2004 from $35.7 million in 2003. The decrease in product revenue was attributable to a decline in sales of our Orbix products.

     Service Revenue. We provide professional services, consisting of consulting and training, technical support for all of our products and, to a limited extent, product customization and enhancement. Consulting services provided by us include training and assisting customers with the effective use and deployment of our products. Customer support generally includes support by means of telephone, e-mail,

-28-

facsimile and customer on-site assistance as well as access to certain product upgrades. Service revenue decreased by 3.0% to $37.3 million in 2004 from $38.5 million in 2003. The decrease in service revenue was attributable to the expiration of support agreements relating to acquired technology no longer requiring support, as well as a general reduction in consulting and support revenue resulting from the decline in product revenue.

Cost of Revenue

     Cost of Product Revenue. Cost of product revenue consists primarily of product media and duplication, manuals, packaging materials, shipping and handling expenses, third-party royalties and, to a lesser extent, the salaries and benefits of certain personnel and related operating costs of computer equipment. Cost of product revenue was $0.2 million, resulting in a product gross margin of 99.2%, in 2004 compared to $0.5 million, resulting in a product gross margin of 98.5%, in 2003. The increase in product gross margin was primarily attributable to shipping and material efficiencies and lower third-party royalty expenses due to a decrease in the proportion of products sold that contain third-party software embedded with our software product offerings.

     Cost of Service Revenue. Cost of service revenue consists primarily of personnel costs for consultancy, training, customer support, product customization and enhancement, and related operating costs of computer equipment and non-billable travel expenses. Cost of service revenue was $11.8 million, resulting in a service gross margin of 68.4%, in 2004 compared to $14.3 million, resulting in a service gross margin of 62.9%, in 2003. The increase in service gross margin was primarily attributable to a reduction in service personnel, as a result of our restructuring plans, coupled with higher utilization rates. The average number of service personnel decreased from 80 in 2003 to 56 in 2004.

Operating Expenses

     Research and Development. Research and development expenses consist primarily of salaries and benefits of research and development personnel, costs of third-party contractors, personnel-related overhead allocation, depreciation expenses arising from the acquisition of computer equipment, software license fees, and related indirect costs. Research and development expenses were $17.2 million, or 25.3% of total revenue, in 2004 compared to $27.1 million, or 36.6% of total revenue, in 2003. The decrease in research and development expenses in dollar amount was primarily the result of cost reduction measures and restructuring plans implemented by management in 2003 (as described below in “Restructuring”). The average number of research and development personnel decreased from 159 in 2003 to 125 in 2004. We expect that research and development expenses will remain at similar aggregate dollar amounts in 2005.

     Sales and Marketing. Sales and marketing expenses consist primarily of salaries, sales commissions and benefits earned by sales and marketing personnel, personnel-related overhead allocation, travel, entertainment, advertising and promotional expenses, and related indirect costs. Sales and marketing expenses were $29.5 million, or 43.4% of total revenue, in 2004 compared to $41.5 million, or 55.9% of total revenue, in 2003. The decrease in sales and marketing expenses in dollar amount was primarily the result of cost reduction measures and restructuring plans implemented by management in 2003 (as described below in “Restructuring”), as well as a decrease in sales commissions of approximately $3.5 million that resulted from lower license revenue and a change in our commission structure during 2004. The average number of sales and marketing personnel decreased from 168 in 2003 to 111 in 2004. We expect that sales and marketing expenses will increase in dollar amount in 2005.

     General and Administrative. General and administrative expenses consist primarily of salaries and benefits of financial, administrative and management personnel, general office administration expenses (rent and occupancy, telephone and other office supply costs), and related indirect costs. General and administrative expenses also include professional fees, liability insurance and depreciation. General and administrative expenses were $8.5 million, or 12.6% of total revenue, in 2004 compared to $10.3 million, or 13.8% of total revenue, in 2003. The decrease in general and administrative expenses in dollar amount was primarily the result of cost reduction measures and restructuring plans implemented by management in

-29-

2003 (as described below in “Restructuring”). The average number of general and administrative personnel decreased from 72 in 2003 to 53 in 2004. We expect that general and administrative expenses will remain at similar aggregate dollar amounts in 2005.

     Amortization of Other Non-Current Assets. Amortization of other non-current assets consists of the amortization of purchased technologies acquired by us, which have reached technological feasibility.

      Amortization of other non-current assets was $0.6 million, or 0.8% of total revenue in 2004, compared to $0.8 million, or 1.1% of total revenue in 2003. The decrease in amortization of other non-current assets is primarily attributable to the full amortization of certain intangible assets. Other non-current assets are amortized on a straight-line basis over three to four years.

     Restructuring. In 2004, we recorded a charge of $0.6 million for severance and benefit costs related to cost reduction actions. Also, during 2004, we released $0.6 million of a restructuring accrual related to severance and benefit costs from previous restructurings, based on the final payments for such severance and benefits. Cash outlays associated with the restructuring plans initiated in 2004, 2003, 2002, and previous periods totaled approximately $6.0 million during 2004, including approximately $2.5 million in severance and related benefits paid to employees worldwide and $3.5 million in facility closure costs.

      In 2003, our management and board of directors approved restructuring plans, which included consolidation of excess facilities, a reduction in workforce and other related costs. Total restructuring costs of $20.5 million have been recorded related to these initiatives. Restructuring expenses included approximately $11.0 million representing the cost of involuntary employee separation and related costs for approximately 278 employees worldwide. Employee separations affected the majority of business functions, job classes and geographies. In addition, the restructuring plans included costs totaling approximately $9.5 million associated with the closure and consolidation of office space, principally in the United States and Ireland.

     Adjustment of Acquisition Liabilities. In October 2004, we received $0.6 million from our insurers in connection with the favorable resolution of an acquisition contingency, relating to litigation costs, which resulted in the recognition of $0.6 million of income.

     Impairment of Intangible Assets and Fixed Assets. In 2004, there was no impairment of intangible assets and fixed assets. In 2003, we recorded a $3.3 million impairment of intangible assets and fixed assets. As a result of unfavorable market conditions and changes in our product strategy, which we identified as indicators of impairment under SFAS 144, we recorded a non-cash impairment charge of $0.1 million, representing the amount by which the carrying value exceeded the fair value of purchased technologies. We also recorded a $3.2 million charge for the fixed assets and related costs, for fixed assets no longer in use in 2003, as a result of the restructuring activities in 2003.

Income (Loss) from Operations

      We generated an operating income of $0.7 million, or 1.1% of total revenue, in 2004 compared to an operating loss of $44.1 million, or 59.5% of total revenue, in 2003. The increase in operating income for 2004 compared to 2003 was primarily the result of the impact of restructuring and impairment charges in 2003 in addition to savings in 2004 from the cost reduction measures and restructuring plans implemented by management in 2003.

Other Income, Net

      Interest income, net, primarily represents interest earned on cash and investment balances. Interest income, net was $0.3 million in 2004 compared to $0.5 million in 2003. The decrease in interest income, net was due primarily to unrealized losses on investments, specifically bonds, that were affected by increasing interest rates.

-30-

      Net exchange loss was $0.3 million in 2004 compared to a net exchange gain of $0.3 million in 2003. The net exchange loss for 2004 was primarily due to the weakening of the U.S. dollar against the Euro offset by a strengthening of the Japanese Yen versus the U.S. Dollar.

Income Taxes

      Income taxes were $0.6 million in 2004 compared to $0.9 million in 2003. The reduction in the provision of income taxes in 2004 compared to 2003 reflects losses incurred domestically and in certain foreign jurisdictions. See “Factors Affecting Future Results—If our effective tax rate increases, our business and financial results would be adversely impacted.”

      At December 31, 2004, we had a net operating loss carryforwards of approximately $107.5 million for U.S. federal income tax purposes, including approximately $65.0 million pre-acquisition losses from the Netfish acquisition, which will expire in tax years 2011 through 2024 if not previously utilized. At December 31, 2004, we also had net operating loss carryforwards of approximately $117.6 million and $2.9 million for Irish and Australian tax purposes, respectively, both of which carry forward indefinitely.

Year Ended December 31, 2003 Compared to Year Ended December 31, 2002

Total Revenue

      Total revenue decreased by 39.8% to $74.2 million in 2003 from $123.2 million in 2002. Total revenue from customers located outside of the United States represented 48.3% of total revenue in 2003 and 38.8% of total revenue in 2002, or $35.9 million and $47.8 million, respectively. The total number of revenue transactions over $250,000 decreased from 84 in 2002 to 62 in 2003, and there was a corresponding decrease in average deal size from approximately $53,000 to $51,000. No customer accounted for more than 10% of our total revenues in 2003 or 2002.

     Product Revenue. Product revenue decreased by 51.3% to $35.7 million in 2003 from $73.5 million in 2002. The decrease in product revenue was attributable to decreased sales of our products, resulting from the effects of the macroeconomic climate’s continuing impact on IT spending and the software market as a whole.

     Service Revenue. Service revenue decreased by 22.8% to $38.5 million in 2003 from $49.8 million in 2002. The decrease in service revenue was principally due to the effects of the macroeconomic climate’s continuing impact on IT spending and the software market as a whole, which resulted in a decrease in demand for consultancy services.

Cost of Revenue

     Cost of Product Revenue. Cost of product revenue was $0.5 million, resulting in a product gross margin of 98.5%, in 2003 compared to $1.7 million, resulting in a product gross margin of 97.7%, in 2002. The increase in product gross margin was primarily attributable to shipping and material efficiencies and lower third-party royalty expenses due to a decrease in the proportion of products sold that contain third-party software embedded with our software product offerings.

     Cost of Service Revenue. Cost of service revenue was $14.3 million, resulting in a service gross margin of 62.9%, in 2003 compared to $25.5 million, resulting in a service gross margin of 48.9%, in 2002. The increase in service gross margin was primarily attributable to a reduction in service personnel, as a result of our restructuring plans, coupled with higher utilization rates. The average number of service personnel decreased from 142 in 2002 to 80 in 2003.

Operating Expenses

     Research and Development. Research and development expenses were $27.1 million, or 36.6% of total revenue, in 2003 compared to $38.3 million, or 31.0% of total revenue, in 2002. The decrease in research and development expenses in dollar amount was primarily the result of cost reduction measures

-31-

and restructuring plans implemented by management in 2002 and 2003 (as described below in “Restructuring”) with the increase in research and development expenses as a percentage of total revenue due to declining revenues. The average number of research and development personnel decreased from 226 in 2002 to 159 in 2003.

     Sales and Marketing. Sales and marketing expenses were $41.5 million, or 55.9% of total revenue, in 2003 compared to $72.9 million, or 59.1% of total revenue, in 2002. The decrease in sales and marketing expenses in dollar amount was primarily the result of cost reduction measures and restructuring plans implemented by management in 2002 and 2003 (as described below in “Restructuring”), in addition to a decrease in promotional and public relations activities of approximately $4.3 million, as well as a decrease in sales commissions of approximately $3.0 million that resulted from lower license revenue during 2003. The average number of sales and marketing personnel decreased from 301 in 2002 to 168 in 2003.

     General and Administrative. General and administrative expenses were $10.3 million, or 13.8% of total revenue, in 2003 compared to $13.3 million, or 10.8% of total revenue, in 2002. The decrease in general and administrative expenses in dollar amount was primarily the result of cost reduction measures and restructuring plans implemented by management in 2002 and 2003 (as described below in “Restructuring”) with the increase in general and administrative expenses as a percentage of total revenue due to declining revenues. The average number of general and administrative personnel decreased from 110 in 2002 to 72 in 2003.

     Amortization of Other Non-Current Assets. Effective January 1, 2002, we adopted SFAS 142, which changed the accounting for goodwill and intangible assets with indefinite lives, but required intangible assets such as purchased technologies to continue to be amortized over their useful economic lives. Upon adoption of SFAS 142 in January 2002, the net carrying amount of assembled workforce of $6.9 million was reclassifed from other non-current assets to goodwill. SFAS 142 requires intangible assets that are amortizable to be reviewed for impairment in accordance with SFAS 144.

      In October 2002, and again in October 2003, we completed our assessment of the carrying value of purchased technologies and the relevant impairment tests as required by SFAS 144. This assessment resulted in a non-cash impairment charge of $28,586,000 and $80,000 in 2002 and 2003, respectively, representing the amount by which the carrying value exceeded the fair value of purchased technologies.

      Amortization of other non-current assets was $0.8 million, or 1.1% of total revenue in 2003, compared to $10.1 million, or 8.2% of total revenue in 2002. The decrease in amortization of other non-current assets is primarily attributable to the reduction in the carrying value of purchased technologies resulting from the impairment charge recorded in October 2002. Other non-current assets are amortized on a straight-line basis over three to four years.

     Restructuring. In 2003, our management and board of directors approved restructuring plans, which included consolidation of excess facilities, a reduction in workforce and other related costs. Total restructuring costs of $20.5 million were recorded related to these initiatives. Restructuring expenses included approximately $11.0 million representing the cost of involuntary employee separation and related costs for approximately 278 employees worldwide. Employee separations affected the majority of business functions, job classes and geographies. In addition, the restructuring plans included costs totaling approximately $9.5 million associated with the closure and consolidation of office space, principally in the United States and Ireland. Cash outlays associated with restructuring plans initiated in 2003, 2002 and 2001 totaled approximately $16.8 million during 2003, including approximately $11.2 million in severance and related benefits paid to employees worldwide and $5.6 million in facility closure costs.

      In 2002, our management and board of directors approved restructuring plans, which included consolidation of excess facilities, a reduction in workforce and other related costs. Total restructuring costs of $20.8 million were recorded related to these initiatives. Restructuring expenses included approximately $12.3 million representing the cost of involuntary employee separation and related costs for approximately 300 employees worldwide. Employee separations affected the majority of business functions, job classes and geographies, with most of the reductions in sales and marketing, engineering and professional services

-32-

functions in the United States and Europe. In addition, the restructuring plans included costs totaling approximately $8.1 million associated with the closure and consolidation of office space, principally in the United States and approximately $0.4 million of other related costs.

     Impairment of Goodwill. Effective January 1, 2002, we adopted the new rules on accounting for goodwill and other non-current assets in accordance with SFAS 142. There was no impairment of goodwill upon adoption of SFAS 142. In October 2002, as required by SFAS 142, we completed the annual impairment test and assessment of the carrying value of goodwill. As a result of unfavorable market conditions and a decline in our market capitalization, this assessment resulted in a non-cash impairment charge of $276.8 million, equivalent to the carrying value of goodwill at October 1, 2002.

     Impairment of Intangible Assets and Fixed Assets. In 2003, we recorded a $3.3 million impairment of intangible assets and fixed assets. As a result of unfavorable market conditions and changes in our product strategy, which we identified as indicators of impairment under SFAS 144, we recorded a non-cash impairment charge of $0.1 million, representing the amount by which the carrying value exceeded the fair value of purchased technologies. We also recorded a $3.2 million charge for the fixed assets and related costs, for fixed assets no longer in use in 2003, as a result of the restructuring activities in 2003.

      In 2002, we recorded a $32.3 million impairment of intangible assets and fixed assets. As a result of unfavorable market conditions and changes in our product strategy, we recorded a non-cash impairment charge of $28.6 million, representing the amount by which the carrying value exceeded the fair value of purchased technologies. We also recorded a $3.7 million charge for the fixed assets and related costs of which $1.6 million was primarily attributable to our implementation of a new sales force automation system that replaced an existing system. The remainder of the write-offs relate to fixed assets no longer in use in 2002, resulting in the reduction of their net book value to nil.

Income (Loss) from Operations

      We generated an operating loss of $44.1 million, or 59.5% of total revenue, in 2003 compared to an operating loss of $368.3 million, or 298.9% of total revenue, in 2002. The operating loss in 2003 and 2002 reflects the decrease in total revenue primarily as a result of general economic conditions affecting the software market as a whole, the non-cash impairment loss of $3.3 million and $309.1 million, and restructuring charge of $20.5 million and $20.8 million incurred in each of the two years.

Other Income, Net

      Interest income, net was $0.5 million in 2003 compared to $1.1 million in 2002. The decrease in interest income, net was due primarily to lower average balances held in these accounts and lower interest rates realized during 2003.

      Net exchange gain was $0.3 million in 2003 compared to a net exchange loss of $0.5 million in 2002. The net exchange gain for 2003 was primarily due to the weakening of the U.S. dollar against the yen.

Income Taxes

      Income taxes were $0.9 million in 2003 compared to $1.5 million in 2002. The reduction in the provision of income taxes in 2003 compared to 2002 reflects losses incurred domestically and in certain foreign jurisdictions. See “Factors Affecting Future Results— If our effective tax rate increases, our business and financial results would be adversely impacted.”

      At December 31, 2003, we had a net operating loss carryforward of approximately $105.4 million for U.S. federal income tax purposes, including approximately $65.0 million pre-acquisition losses from the Netfish acquisition, which will expire in tax years 2011 through 2023 if not previously utilized. At December 31, 2003, we also had net operating loss carryforwards of approximately $105.9 million and $2.9 million for Irish and Australian tax purposes, respectively, both of which carry forward indefinitely.

-33-

Exposure to Currency Fluctuations

      Our Consolidated Financial Statements are prepared in U.S. dollars, our functional currency. A percentage of our revenues, expenses, assets and liabilities are denominated in currencies other than our functional currency. Fluctuations in exchange rates may have a material adverse effect on our results of operations, particularly our operating margins, and could also result in exchange gains and losses. As a result of currency fluctuations, we recognized an exchange loss of $0.3 million in 2004 and an exchange gain of $0.3 million in 2003. We cannot accurately predict the impact of future exchange rate fluctuations on our results of operations. We have in the past sought to hedge the risks associated with fluctuations in exchange rates of the Irish pound and the euro to the dollar. However, because the majority of our sales and expenses are currently made in U.S. dollar, we no longer enter into foreign currency forward exchange contracts to manage exposure related to transactions denominated in foreign currencies. In the future, we may undertake transactions to hedge the risks associated with fluctuations in exchange rates if the risk from foreign currency exposure increases due to a decrease in the percentage of U.S. dollar-based transactions. See also Item 11 “Quantitative and Qualitative Disclosure About Market Risk.” We had no derivative or hedging transactions in 2004, 2003 and 2002.

B. Liquidity and Capital Resources

      Our capital requirements relate primarily to facilities, employee infrastructure and working capital requirements. Historically, we have funded our cash requirements primarily through the public and private sales of equity securities, operating leases, and from operations. At December 31, 2004, we had cash and cash equivalents, restricted cash, and marketable securities of $59.9 million, representing an increase of $3.3 million from December 31, 2003.

      Net cash provided by operating activities was $4.8 million in 2004 compared to net cash used in operating activities of $3.4 million in 2003 and $66.8 million in 2002. The increase in cash provided by operating activities from 2003 to 2004 reflects primarily an increase in net income, a decrease in accounts receivable, and the net sales of marketable securities, offset by a decrease in accruals and other liabilities and deferred revenue. The decrease in cash used in operating activities from 2002 to 2003 reflects primarily decreases in net loss, accounts receivable, prepaid expenses and other assets, the sale of marketable securities, and an increase in restricted cash and other accrued liabilities relating to restructuring charges, partially offset by a decrease in deferred revenue.

      As of December 31, 2004, we had approximately $3.5 million of irrevocable letters of credit outstanding in connection with facility leases and the satisfaction of amounts owed to a previous landlord, of which approximately $0.5 million renews annually for the duration of the lease terms, which expire in July 2006 and May 2007 and $3.0 million is payable upon demand. The investments pledged for security of the letters of credit are presented as restricted cash in the consolidated balance sheets.

      To the extent that non-cash items increase or decrease our future operating results, there will be no corresponding impact on our cash flows. After excluding the effects of these non-cash charges, the primary changes in cash flows relating to operating activities result from changes in working capital. Our primary source of operating cash flows is the collection of accounts receivable from our customers. Our operating cash flows are also impacted by the timing of payments to our vendors for accounts payable. We generally pay our vendors and service providers in accordance with the invoice terms and conditions. The timing of cash payments in future periods will be impacted by the terms of accounts payable arrangements and management’s assessment of our cash inflows.

      Net cash used in investing activities was $1.3 million, $1.2 million and $5.4 million in 2004, 2003 and 2002, respectively. The increase from 2003 to 2004 relates primarily to the lack of proceeds from the disposal of property and equipment. The decrease from 2002 to 2003 related primarily to a decrease in capital investments. We expect capital expenditures in fiscal year 2005 to remain flat.

      Net cash provided by financing activities was $1.6 million, $2.2 million and $66.0 million in 2004, 2003, and 2002, respectively. In 2004 and 2003, net cash provided by financing activities resulted primarily

-34-

from the proceeds from the exercise of stock options and the sale of stock under our 1999 Employee Stock Purchase Plan. In 2002, net cash provided by financing activities resulted primarily from the proceeds from the completion of our public offering in February 2002 of $63.4 million and $2.6 million from the proceeds from the exercise of stock options and the sale of stock under our 1999 Employee Stock Purchase Plan.

      We are obligated to make average lease payments of approximately $3.0 million per year through 2023 (subject to an option to exit in 2013) with respect to our Dublin, Ireland facility; approximately $2.2 million per year through 2006 with respect to IONA U.S.’s Waltham, Massachusetts facility; approximately $0.6 million per year through 2006 with respect to our U.S. subsidiary’s San Mateo, California facility; approximately $0.3 million per year through 2014 (subject to an option to exit in 2009) with respect to our Reading, U.K. facility; approximately $0.2 million per year through 2007 with respect to IONA U.S.’s New York, New York facility; approximately $0.2 million through 2006 with respect to IONA Japan’s Tokyo, Japan facility and approximately $0.1 million through 2006 with respect to our London, U.K. facility.

      As of December 31, 2004, future minimum lease payments under contractual operating lease obligations includes approximately $7.6 million provided for as accrued restructuring costs and is included in other accrued liabilities and other non-current liabilities on the consolidated balance sheets.

      At December 31, 2004 and 2003 we had $56.4 million and $52.9 million in cash, cash equivalents and marketable securities, respectively. We anticipate our operating expenses will remain relatively stable for the foreseeable future and as a result we intend to fund our operating expenses through cash flows from operations. We expect to use our cash resources to fund capital expenditures as well as acquisitions or investments in complementary businesses, technologies or product lines. We believe that our current cash, cash equivalents and marketable securities and cash flows from operations will be sufficient to meet our anticipated cash requirements for working capital and capital expenditures for at least the next twelve months. The foregoing estimate of the period of time through which our current sources of liquidity will be sufficient to finance our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary.

      It is possible that, when needed, adequate funding may not be available to us or, if available, may not be available on terms favorable to us. In addition, we may decide to issue additional equity or debt securities for such funding, which could dilute the ownership of existing shareholders. Any shortfall in our capital resources could result in our limiting the introduction or marketing of new products and services, which could have a material adverse effect on our business, financial condition and results of operations.

C. Research and Development, Patents and Licenses, etc.

      For a discussion of our research and development activities, patents and licenses, please see Item 4.B. “Business Overview—Product Development and Management” and “Business Overview—Patents and Proprietary Technology.”

      The total amount spent in the last three years on IONA-sponsored research and development activities is $82.6 million excluding intangible assets and in-process research and development. Of that amount, $17.2 million was spent in 2004, $27.1 million was spent in 2003 and $38.3 million was spent in 2002.

D. Trend Information

      For information about our expectations regarding our future operating expenses and capital resources, please see Items 5.A. “Operating Results” and 5.B. “Liquidity and Capital Resources.”

E. Off-Balance Sheet Arrangements

      Not Applicable.

F. Tabular Disclosure of Contractual Obligations

      We lease office space under non-cancelable operating leases with various expiration dates through 2013. Future minimum lease payments under all operating leases as of December 31, 2004 are as follows:

	Payment Due by period
			Less than		1-3		3-5		More than
Contractual Obligations	Total		1 Year		Years		Years		5 Years
	(U.S. dollars in thousands)
Operating Lease Obligations	$	32,564	$	6,725	$	8,462	$	6,479	$	10,898

      As of December 31, 2004, approximately $7.6 million of the $32.6 million contractual operating lease obligations has been accrued as a result of our restructuring plans initiated in 2003, 2002, and 2001.

      As of December 31, 2004, approximately $0.4 million of contractual severance obligations have been accrued as a result of our restructuring plans in 2004.

G. Safe Harbor

      The safe harbor provided in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended applies to forward-looking information provided pursuant to Item 5.F above.

      The following is a brief description of each of our share option schemes:

Executive Share Option Scheme

      In 1995, we adopted the Executive Share Option Scheme, under which we reserved 1,125,500 ordinary shares for issuance. Options under the Executive Share Option Scheme may only be granted to our directors and full-time employees or those of one of our subsidiaries and must have an exercise price that is not less than the par value of the ordinary shares. Options lapse when not exercised:

•  within seven years of the date of grant;

•  twelve months after the death of an optionee; or

•  prior to termination of the optionee’s employment for any reason, although our Board of Directors has discretion to delay lapse in individual cases.

      As of December 31, 2004, an aggregate of 13,170 of our ordinary shares remain issuable upon the exercise of options outstanding and options available for grant under the Executive Share Option Scheme. Pursuant to the terms of the Executive Share Option Scheme, we may not grant options under the scheme after May 19, 2005.

1997 Share Option Scheme

      Our Board of Directors and shareholders approved the 1997 Share Option Scheme in 1997, and approved amendments in 1998, 2000 and 2001 to increase the number of ordinary shares reserved for issuance under the 1997 Share Option Scheme. The 1997 Share Option Scheme, as amended, provides for the issuance of up to 12,900,000 of our ordinary shares pursuant to share option grants to our employees, consultants, directors and officers. Generally, under the 1997 Share Option Scheme, options are not transferable by the option holder except by will or by the laws of descent and distribution. Options granted under the 1997 Share Option Scheme expire ten years from the date of grant or five years from the date of grant in the case of an incentive stock option granted to an employee holding more than 10% of our total combined voting power.

      Subject to the provisions of the 1997 Share Option Scheme, the Compensation Committee has the authority to select the optionees and determine the terms of the options granted, including:

•  the number of shares subject to each option;

•  the date the option becomes exercisable;

•  the exercise price of the option (which in the case of an incentive stock option cannot be less than the market price of the ordinary shares as of the date of grant or, in the case of an employee holding more than 10% of the combined voting power of IONA, 110% of the market price of the ordinary shares as of the date of grant);

•  the duration of the option; and

•  the time, manner and form of payment upon exercise of an option.

      As of December 31, 2004, an aggregate of 9,816,261 of our ordinary shares remain issuable upon the exercise of options outstanding and options available for grant under the 1997 Share Option Scheme.

1997 Director Share Option Scheme

      Our Board of Directors and shareholders approved the 1997 Director Share Option Scheme in 1997, and approved an amendment in 2002 to increase the number of ordinary shares reserved for issuance under the 1997 Director Share Option Scheme from 250,000 to 500,000 shares. The 1997 Director Share Option Scheme provides for the automatic grant of options at periodic intervals to our non-employee directors.

-45-

      Under the 1997 Director Share Option Scheme, each of our directors who is not also one of our employees or officers will automatically receive an option to purchase 30,000 ordinary shares on the date such person is first elected to our Board of Directors. In addition, each non-employee director will automatically receive (1) an option to purchase an additional 21,000 ordinary shares at the time of each annual meeting of shareholders at which such director is re-elected by rotation and (2) an option to purchase an additional 3,000 ordinary shares at the time of each other annual meeting of shareholders following which such person will continue to serve as a director without re-election, provided, however, that such person has participated in no fewer than 75% of the meetings of our Board of Directors held in the period measured from the date of the previous annual meeting of shareholders and provided also that no option to purchase ordinary shares will be granted to a non-employee director unless at least one year has elapsed since the date on which the non-employee director was granted an option to purchase 30,000 ordinary shares on his first election to our Board of Directors. The exercise price per share for all options granted under the 1997 Director Share Option Scheme will be equal to the fair market value of the ordinary shares on the date of grant. All options granted under the 1997 Director Share Option Scheme are exercisable in three equal annual installments, beginning on the date of grant of the option. The options accelerate and become exercisable in full, however, in the event the optionholder’s service on our Board of Directors ceases by reason of his or her death or permanent disability or in the event of an acquisition of IONA. The term of each option will be for a period of ten years from the date of grant. As of December 31, 2004, an aggregate of 446,000 ordinary shares remain issuable upon the exercise of options outstanding and options available for grant under the 1997 Director Share Option Scheme.

Genesis Development Corporation 1997 Stock Option Plan

      In connection with our 2000 acquisition of Genesis Development Corporation (Genesis), all of the outstanding stock options under the Genesis Development Corporation 1997 Stock Option Plan were converted into options to purchase our ordinary shares. As of December 31, 2004, an aggregate of 228 of our ordinary shares remained reserved for issuance upon exercise of the outstanding converted Genesis stock options. We do not intend to grant any more options under the Genesis 1997 Stock Option Plan.

Object-Oriented Concepts, Inc. Stock Option Plan

      In connection with our 2001 acquisition of Object-Oriented Concepts, Inc. (OOC), all of the outstanding stock options under the Object-Oriented Concepts, Inc. Stock Option Plan were converted into options to purchase our ordinary shares. As of December 31, 2004, there were no outstanding options under the OOC Stock Option Plan. We do not intend to grant any more options under the OOC Stock Option Plan.

Netfish Technologies, Inc. 1999 Stock Option Plan

      In connection with our 2001 acquisition of Netfish Technologies, Inc. (Netfish), all of the outstanding stock options under the Netfish Technologies, Inc. 1999 Stock Option Plan were converted into options to purchase our ordinary shares. As of December 31, 2004, an aggregate of 29,366 of our ordinary shares remained reserved for issuance upon exercise of the outstanding converted Netfish stock options. We do not intend to grant any more options under the Netfish 1999 Stock Option Plan.

1999 Employee Share Purchase Plan

      In 1999, we established a qualified Employee Share Purchase Plan. Our Board of Directors and shareholders approved in 2003 an amendment to the 1999 Employee Share Purchase Plan to increase the number of our ordinary shares issuable under the plan to 2,000,000. All of our employees and employees of our participating subsidiaries who are employed full-time for more than five months in any calendar year are eligible to participate. The purchase price per ordinary share for each payment period (a six-month period commencing February 1 and August 1 and ending July 31 and January 31, respectively, in each year) is the lesser of (1) 85% of the average market price of our ADSs on the first business day of the payment period and (2) 85% of the average market price of our ADSs on the last business day of the

-46-

payment period, in either event rounded up to the nearest cent. In each payment period, an employee may authorize payroll deductions in an amount not less than 1% but not more than 10% of the employee’s salary for participation in the 1999 Employee Share Purchase Plan. Rights under the 1999 Employee Share Purchase Plan terminate in certain specified events including retirement, resignation and death. Once enrolled, an employee may withdraw from the 1999 Employee Share Purchase Plan (in whole but not in part) at any time prior to the last day of a six month payment period by delivering a written withdrawal notice to IONA. An employee who has previously withdrawn must file a new authorization at least ten days before the first day of the next payment period in which he or she wishes to participate. Unless terminated sooner, the 1999 Employee Share Purchase Plan terminates on June 9, 2009. As of December 31, 2004, 1,096,984 shares have been issued under the 1999 Employee Share Purchase Plan.

The Transfer Agent and Registrar for our ADRs is Deutsche Bank Trust Company Americas.

Nasdaq Stock Market Corporate Governance Disclosures

      Nasdaq rules require any foreign issuer that follows home country practice in lieu of any qualitative listing requirement to disclose in its annual reports filed with the Securities and Exchange Commission that it does not follow such qualitative listing requirement and to describe the home country practice followed by the issuer in lieu of such requirement. At the time of our initial public offering in February 1997, we were granted an exemption from the minimum quorum requirement for meetings of the holders of our Ordinary Shares. In lieu of complying with the Nasdaq minimum quorum requirement, we have adhered since the time of our initial public offering, and we will continue to adhere, to the accepted practice in Ireland, our home country, that three (3) or more persons entitled to vote, each being a member or a proxy for a member or a duly authorized representative of a corporate member, shall constitute a quorum at general meetings of our shareholders.

C. Material Contracts

      We have entered into Change in Control Agreements with our executive officers, the form of which has been filed as Exhibit 4.13 to our annual report on Form 20-F for the year ended December 31, 2002 and incorporated herein by reference. Under each of these agreements, if there is a change in control of IONA and the surviving company does not assume IONA’s stock option plans or provide the executive officer with comparable substitute options, the executive officer’s unvested stock options will vest. In addition, if the executive officer’s employment is terminated (1) without cause within the period beginning three months prior to the announcement of the change in control and ending two years after the change in control or (2) by the executive officer for good reason within two years after the change in control, the executive officer’s unvested stock options will vest and the executive officer will be entitled to continued health, vision and dental insurance benefits and a severance payment. The executive officer’s severance payment will equal two times the sum of the executive officer’s highest annual base salary during the period commencing immediately prior to the change of control through the date of termination and highest annual target bonus during the period commencing the calendar year prior to the change of control through the calendar year of the date of termination. In addition, from time to time, on a discretionary basis, we offer severance benefits to our employees, including our executive officers, in the event of employment termination under certain circumstances. We may suspend or discontinue offering severance benefits at any time.

      For information concerning the employment agreement with our Chief Executive Officer, please see Item 6.B. “Compensation.”

      For information on additional material contracts, please see Item 4, “Information on the Company.”

D. Exchange Controls

      Irish exchange control regulations ceased to apply from and after December 31, 1992. Except as indicated below, there are no restrictions on non-residents of Ireland dealing in domestic securities, which includes shares or depositary receipts of Irish companies such as us, and dividends and redemption proceeds (subject to the withholding where appropriate of withholding tax as described under Item 10.E. “Taxation”) are freely transferable to non-resident holders of such securities.

      The Financial Transfers Act, 1992 was enacted in December 1992. This Act gives power to the Minister for Finance of Ireland to make provision for the restriction of financial transfers between Ireland and other countries. Financial transfers are broadly defined and include all transfers which would be movements of capital or payments within the meaning of the treaties governing the European Communities. The acquisition or disposal of ADRs representing shares issued by an Irish incorporated company, like our ADRs, and associated payments may fall within this definition. In addition, dividends or interest payments or payments on redemption or purchase of shares, debentures or other securities in an Irish incorporated company and payments on a liquidation of an Irish incorporated company would fall within this definition. Currently, orders under this Act prohibit any financial transfers with respect to funds, financial assets or economic resources belonging to: certain persons or entities associated with Osama bin Laden, the al-Qaeda network and the Taliban of Afghanistan; certain persons related to governmental functions in Burma/ Myanmar; senior members of the Zimbabwean government; Slobodan Milosevic and persons associated with Slobodan Milosevic; certain persons or entities associated with Iraq; certain persons formerly related to governmental functions in Liberia or any person, entity or body listed in EC Counter Terrorism measures (Council Decision 2004/306/ EC).

      We do not anticipate that orders under the Financial Transfers Act, 1992 will have a material effect on our business, results of operations or financial condition.

E. Taxation

Irish Tax Considerations

      The following is a general summary of certain Irish tax consequences applicable to Irish Holders and U.S. Holders (as defined below in this summary) in respect of the purchase, ownership and disposition of ordinary shares or ADSs evidenced by ADRs.

      This summary is based on Irish taxation laws currently in force, regulations promulgated thereunder, the current provisions of the Ireland-United States Double Taxation Convention (the Treaty), specific proposals to amend any of the forgoing publicly announced prior to the date hereof and the currently published administrative practices of the Irish Revenue Commissioners, all as of the date of this annual report. Taxation laws are subject to change, from time to time, and no representation is or can be made as to whether such laws will change, or what impact, if any, such changes will have on the statements contained in this summary. It is assumed that any proposed amendments will be enacted in the form proposed. No assurance can be given that proposed amendments will be enacted as proposed, or that legislative or judicial changes, or changes in administrative practice, will not modify or change the statements expressed herein.

      This summary is of a general nature only. It does not constitute legal or tax advice nor does it discuss all aspects of Irish taxation that may be relevant to any particular Irish Holder or U.S. Holder of ordinary shares or ADSs.

HOLDERS OF ORDINARY SHARES OR ADSs ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE APPLICATION OF IRISH TAXATION LAWS TO THEIR PARTICULAR CIRCUMSTANCES IN RELATION TO THE PURCHASE, OWNERSHIP OR DISPOSITION OF ORDINARY SHARES OR ADSs.

      The summary only applies to Irish Holders and U.S. Holders that legally and beneficially hold their ordinary shares or ADSs evidenced by ADRs as capital assets (i.e. investments) and does not address

-53-

special classes of holders including, but not limited to, dealers in securities, insurance companies, pension schemes, employee share ownership trusts, collective investment undertakings, charities, tax-exempt organizations, financial institutions and close companies, each of which may be subject to special rules not discussed below.

(i) Irish Tax Considerations Applicable to Irish Holders

      For the purposes of this summary, an “Irish Holder” means a holder of ordinary shares or ADSs evidenced by ADRs that (i) beneficially owns the ordinary shares or ADSs registered in their name; (ii) in the case of individual holders, are resident, ordinarily resident and domiciled in Ireland under Irish taxation laws; (iii) in the case of holders that are companies, are resident in Ireland under Irish taxation laws; and (iv) are not also resident in any other country under any double taxation agreement entered into by Ireland.

      For Irish taxation purposes, Irish Holders of ADSs will be treated as the owners of the underlying ordinary shares represented by such ADSs.

Taxation of Dividends

      We do not expect to pay dividends in the foreseeable future. Should we begin paying dividends, such dividends will generally be subject to dividend withholding tax (DWT) in Ireland at the standard rate of income tax (currently 20%). Where DWT applies, we will be responsible for withholding such tax at source.

      Corporate Irish Holders will generally be entitled to claim an exemption from DWT by delivering a declaration to us in the form prescribed by the Irish Revenue Commissioners. Such corporate Irish Holders will generally not otherwise be subject to Irish tax in respect of dividends received.

      Individual Irish Holders will be subject to income tax on the gross amount of any dividend (that is the amount of the dividend received plus any DWT withheld), at their marginal rate of tax (currently either 20% or 42% depending on the individual’s circumstances). Individual Irish Holders will be able to claim a credit against their resulting income tax liability in respect of DWT withheld.

      Individual Irish Holders may, depending on their circumstances, also be subject to the Irish health levy of 2% and pay related social insurance contribution of up to 3% in respect of their dividend income.

Disposals of Ordinary Shares or ADSs

      Irish Holders that acquire ordinary shares or ADSs will generally be considered, for Irish tax purposes, to have acquired their ordinary shares or ADSs at a base cost equal to the amount paid for the ordinary shares or ADSs. On subsequent dispositions, ordinary shares or ADSs acquired at an earlier time will generally be deemed, for Irish tax purposes, to be disposed of on a “first in first out” basis before ordinary shares or ADSs acquired at a later time.

      Irish Holders that dispose of their ordinary shares or ADSs will be subject to Irish capital gains tax (CGT) to the extent that the proceeds realized from such disposition exceed the indexed base cost of the ordinary shares or ADSs disposed of and any incidental expenses. The current rate of CGT is 20%. Indexation of the base cost of the ordinary shares or ADSs will only be available up to December 31, 2002, and only in respect of ordinary shares or ADSs held for more than 12 months prior to their disposal.

      Irish Holders that have unutilized capital losses from other sources in the current, or any previous tax year, can generally apply such losses to reduce gains realized on the disposal of the ordinary shares or ADSs.

      An annual exemption allows individuals to realize chargeable gains of up to€1,270 in each tax year without giving rise to CGT. This exemption is specific to the individual and cannot be transferred between spouses. Irish Holders are required, under Ireland’s self-assessment system, to file a tax return reporting any chargeable gains arising to them in a particular tax year.

-54-

      Where disposal proceeds are received in a currency other than euro they must be translated into euro amounts to calculate the amount of any chargeable gain or loss. Similarly, acquisition costs denominated in a currency other than euro must be translated at the date of acquisition into euro amounts.

      Irish Holders that realize a loss on the disposition of ordinary shares or ADSs will generally be entitled to offset such allowable losses against capital gains realized from other sources in determining their CGT liability in a year. Allowable losses which remain unrelieved in a year may generally be carried forward indefinitely for CGT purposes and applied against capital gains in future years.

      Transfers between spouses will not give rise to any chargeable gain or loss for CGT purposes with the acquiring spouse acquiring the same pro rata base cost and acquisition date as that of the transferring spouse.

Capital Acquisitions Tax

      A gift or inheritance of ordinary shares or ADSs will fall within the charge to Irish capital acquisitions tax (CAT). CAT is currently chargeable at a rate of 20% on the value of gifts or inheritances above specified tax free thresholds. Different classes of tax free thresholds apply depending upon the relationship between the donor and the recipient. These tax free thresholds are also affected by the value of previous gifts or inheritances received since December 5, 1991. CAT is generally payable by the recipient of the gift or inheritance. Gifts or inheritances between spouses are not subject to Irish CAT. Effective January 1, 2003, gifts of up to €3,000 of the total value of all gifts received from any one individual in any year up to December 31 can be received without triggering a charge to CAT. This exemption does not generally apply to inheritances. Where a charge to CGT and CAT arises on the same event, CAT payable on the event can be reduced by the amount of the CGT payable.

Stamp Duty

      Irish stamp duty, which is a tax imposed on certain documents, is payable on all transfers of ordinary shares (other than transfers made between spouses, transfers made between 90% associated companies, or certain other exempt transfers) regardless of where the document of transfer is executed. Irish stamp duty is also payable on electronic transfers of ordinary shares.

      A transfer of ordinary shares made as part of a sale or gift will generally be stampable at the ad valorem rate of 1% of the value of the consideration received for the transfer, or, if higher, the market value of the shares transferred. A minimum stamp duty of €1.00 will apply to a transfer of ordinary shares. Where the consideration for a sale is expressed in a currency other than euro, the duty will be charged on the euro equivalent calculated at the rate of exchange prevailing at the date of the transfer.

      Transfers of ordinary shares where no beneficial interest passes (e.g. a transfer of shares from a beneficial owner to a nominee), will generally be exempt from stamp duty if the transfer form contains an appropriate certification, otherwise a nominal stamp duty rate of €12.50 will apply.

      Transfers of ADRs (representing ADSs) by Irish Holders are generally exempt from Irish stamp duty.

      Transfers of ordinary shares from the Depositary or the Depositary’s custodian upon surrender of ADRs for the purposes of withdrawing the underlying ordinary shares from the ADS/ ADR system, and transfers of ordinary shares to the Depositary or the Depositary’s custodian for the purposes of transferring ordinary shares onto the ADS/ ADR system, will be stampable at the ad valorem rate of 1% of the value of the shares transferred if the transfer relates to a sale or contemplated sale or any other change in the beneficial ownership of ordinary shares. Such transfers will be exempt from Irish stamp duty if the transfer does not relate to or involve any change in the beneficial ownership in the underlying ordinary shares and the transfer form contains the appropriate certification. In the absence of an appropriate certification, stamp duty will be applied at the nominal rate of €12.50.

-55-

      The person accountable for the payment of stamp duty is the transferee or, in the case of a transfer by way of gift or for consideration less than the market value, both parties to the transfer. Stamp duty is normally payable within 30 days after the date of execution of the transfer. Late or inadequate payment of stamp duty will result in liability for interest, penalties and fines.

(ii)     Irish Tax Considerations Applicable to U.S. Holders

      Solely for the purposes of this summary of Irish Tax Considerations, a “U.S. Holder” means a holder of ordinary shares or ADSs evidenced by ADRs that (i) beneficially owns the ordinary shares or ADSs registered in their name; (ii) is resident in the United States for the purposes of the Treaty; (iii) in the case of an individual holder, is not also resident or ordinarily resident in Ireland for Irish tax purposes; (iv) in the case of a corporate holder, is not a resident in Ireland for Irish tax purposes and is not ultimately controlled by persons resident in Ireland; and (v) is not engaged in any trade or business and does not perform independent personal services through a permanent establishment or fixed base in Ireland.

      For Irish taxation purposes, and for the purposes of the Treaty, U.S. Holders of ADSs will be treated as the owners of the underlying ordinary shares represented by such ADSs.

Taxation of Dividends

      We do not expect to pay dividends in the foreseeable future. Should we begin paying dividends, such dividends will generally be subject to dividend withholding tax (DWT) in Ireland at the standard rate of income tax (currently 20%). Where DWT applies, we will be responsible for withholding such tax at source.

      Dividends paid by us to U.S. Holders of ordinary shares will be exempt from DWT if, prior to the payment of such dividends, the recipient U.S. Holder delivers to us a declaration, a certificate of residency and, in the case of U.S. Holders that are corporations, an auditor’s certificate, each in the form prescribed by the Irish Revenue Commissioners.

      Special DWT arrangements may be available to U.S. Holders of ADSs evidenced by ADRs, as the Depositary for the ADSs (Deutsche Bank Trust Company Americas, the depositary under the Deposit Agreement dated as of April 26, 2004 among IONA, Deutsche Bank Trust Company Americas and the holders from time to time of ADSs issued thereunder) has entered into an intermediary agreement with the Irish Revenue Commissioners for DWT purposes. Under such an agreement, it is possible for the Depositary to receive dividends from us and pass such dividends onto U.S. Holders of ADSs on a gross basis, without DWT, if either:

•  the ADR register maintained by the Depositary shows the U.S. Holder as having a U.S. address on the register; or

•  where there is an intermediary between the Depositary and the beneficial holder of ADSs, the Depositary receives confirmation from the intermediary that the beneficial owner’s address in the intermediary’s records is in the U.S.

      Where the above procedures have not been complied with and DWT is withheld from dividend payments to U.S. Holders of ordinary shares or ADSs evidenced by ADRs, such U.S. Holders can apply to the Irish Revenue Commissioners claiming a full refund of DWT paid by filing a declaration, a certificate of residency and, in the case of U.S. Holders that are corporations, an auditor’s certificate, each in the form prescribed by the Irish Revenue Commissioners.

      The DWT rate applicable to U.S. Holders is reduced to 5% under the terms of the Treaty for corporate U.S. Holders holding 10% or more of our voting shares, and to 15% for other U.S. Holders. While this will, subject to the application of Article 23 of the Treaty, generally entitle U.S. Holders to claim a partial refund of DWT from the Irish Revenue Commissioners, U.S. Holders will, in most circumstances, likely prefer to seek a full refund of DWT under Irish domestic legislation.

-56-

Capital Gains on Disposals of Ordinary Shares or ADSs

      U.S. Holders will not be subject to Irish capital gains tax (CGT) on the disposal of ordinary shares or ADSs provided that such ordinary shares or ADSs are quoted on a stock exchange at the time of disposition. A stock exchange for this purpose includes, among others, the Irish Stock Exchange (ISE) or the Nasdaq National Market (NASDAQ). While it is our intention to continue the quotation of our ordinary shares on the ISE and the quotation of ADSs on NASDAQ, no assurances can be given in this regard.

      If, for any reason, our ADSs cease to be quoted on NASDAQ and our ordinary shares cease to be quoted on the ISE, U.S. Holders will not be subject to CGT on the disposal of their ordinary shares or ADSs provided that the ordinary shares or ADSs do not, at the time of the disposal, derive the greater part of their value from land, buildings, minerals, or mineral rights or exploration rights in Ireland.

Irish Capital Acquisitions Tax

      A gift or inheritance of ordinary shares or ADSs will fall within the charge to Irish capital acquisitions tax (CAT) because our ordinary shares are considered to be Irish property for CAT purposes. CAT is currently chargeable at a rate of 20% on the value of gifts or inheritances above specified tax free thresholds. Different classes of tax free thresholds apply depending upon the relationship between the donor and the recipient. These tax free thresholds are also affected by the value of previous gifts or inheritances received since December 5, 1991. Gifts or inheritances between spouses are not subject to CAT.

      Effective January 1, 2003, gifts of up to €3,000 of the total value of all gifts received from any one individual in any year up to December 31 can be received without triggering a charge to CAT. This exemption does not generally apply to inheritances.

      In a case where an inheritance of ordinary shares or ADSs is subject to both CAT and U.S. federal estate tax, the Estate Tax Convention between Ireland and the U.S. should allow for the crediting, in whole or in part, of the CAT against the U.S. federal estate tax payable. Similar relief is not available in a case where a gift of ordinary shares or ADSs evidenced by ADRs is subject both to CAT and U.S. federal gift tax as the Estate Tax Convention only applies to estate taxes.

Stamp Duty

      Irish Stamp Duty will apply to transfers of ordinary shares or ADSs by U.S. Holders on the same basis as outlined above for Irish Holders.

Certain U.S. Federal Income Tax Considerations

      The following discussion summarizes certain of the material U.S. federal income tax considerations for U.S. Holders from the purchase, ownership and disposition of our ordinary shares or ADSs which evidence the ADRs. The following discussion assumes that, for U.S. federal income tax purposes, U.S. Holders will be treated as the owners of our underlying ordinary shares represented by the ADSs. The following discussion is based on the Internal Revenue Code of 1986, as amended (the Code), current and proposed Treasury Regulations, judicial decisions and published administrative positions of the Internal Revenue Service, all as in effect on the date of this Annual Report, and all of which are subject to change, possibly with retroactive effect. In particular, numerous provisions of current U.S. federal income tax law (including certain tax rates referred to herein) are scheduled to change in future years, without further legislative action, as a result of “sunset” provisions included as part of legislation passed in 2001 and 2003. For purposes of this discussion, a person is a U.S. Holder if such person holds ordinary shares or ADSs and if such person is:

• a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or who meets the substantial presence residency test under U.S. federal income tax laws;

-57-

• a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) that is created or organized under the laws of the United States, any of the fifty states or the District of Columbia, unless otherwise provided by Treasury Regulations;

• an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of source; or

• a trust, if a U.S. court is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all substantial decisions of the trust.

      This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a U.S. Holder based on such holder’s particular situation. For example, the following discussion does not address the application of the alternative minimum tax rules or rules applicable to U.S. Holders in special circumstances. Special rules may apply to a U.S. Holder who is:

• a bank, thrift, insurance company, regulated investment company, or other financial institution or financial service company;

• a broker or dealer in securities or foreign currency;

• a person who has a functional currency other than the U.S. dollar;

• a partnership or other flow-through entity (including a limited liability company treated as a partnership for U.S. federal income tax purposes);

• an S corporation;

• a person subject to alternative minimum tax;

• a person who owns our ordinary shares or ADSs evidenced by ADRs as part of a straddle, hedging transaction, conversion transaction, constructive sale transaction or other risk-reduction transaction;

• a tax-exempt entity;

• investors who own (directly, indirectly or through attribution) 10% or more of our outstanding voting shares;

• a person who has ceased to be a U.S. citizen or to be taxed as a resident alien; or

• a person who acquired our ordinary shares or ADSs evidenced by ADRs in connection with employment or the performance of services generally.

      The following discussion does not address any aspect of state, local or non-U.S. tax laws or any aspect of U.S. estate or gift taxation and does not address aspects of U.S. federal income taxation applicable to U.S. Holders holding options, warrants, or other rights to acquire our ordinary shares. Further, this discussion generally considers only U.S. Holders that hold their ordinary shares or ADSs as capital assets and does not consider the tax treatment of holders who are partnerships or who hold ordinary shares or ADSs through a partnership or other pass-through entity.This discussion does not apply to any person who is not a U.S. Holder or to any person who does not hold ordinary shares or ADSs.

      This discussion also assumes that we will not be treated as a controlled foreign corporation. Under the Code, a controlled foreign corporation generally means any foreign corporation if, on any day during its taxable year, more than 50% of either the total combined voting power of all classes of stock of the corporation entitled to vote, or the total value of the stock of the corporation, is owned, directly, indirectly or by attribution, by U.S. persons who each, in turn, own directly, indirectly or by attribution, 10% or more of the total combined voting power of all classes of stock of the corporation entitled to vote. Further, this discussion assumes that we are not a “collapsible corporation” as defined in the Code. If a partnership (or an entity treated as a partnership) holds our ordinary shares, the tax treatment of a partner will generally depend upon the status of the partner and upon the activities of the partnership. If you are a partner in a partnership (or an interest holder in an entity treated as a partnership), you should consult your tax advisor.

-58-

U.S. HOLDERS OF OUR ORDINARY SHARES OR ADSs ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE U.S. FEDERAL, STATE, LOCAL OR NON-U.S. TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP OR DISPOSITION OF ORDINARY SHARES OR ADSs APPLICABLE IN THEIR PARTICULAR TAX SITUATIONS.

Dividends

      We have never paid dividends, and do not expect to pay dividends in the foreseeable future. In general, and subject to the discussion below under “Passive Foreign Investment Company,” if we make certain distributions on our ordinary shares and with respect to ADSs, U.S. Holders will be required to include in gross income as dividend the gross amount (i.e., including the amount of any Irish tax withheld) of the distributions, on the date the distributions are received (or treated as received) to the extent the distributions are paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes. Under new U.S. tax rules, distributions by certain qualified foreign corporations are eligible for a new reduced federal income tax rate. Qualified foreign corporations include foreign corporations that are “eligible for benefits” under a “comprehensive income tax treaty” that the Internal Revenue Service determines is satisfactory. Distributions from foreign corporations also qualify for the reduced tax rate if the distributions are received with respect to stock that is “readily tradable on an established securities market in the United States.” Accordingly, provided that these rules are satisfied, dividends paid to an individual U.S. Holder will be taxed at a maximum rate of 15%, provided that the shares or ADSs with respect to which such dividends are paid are held by the individual U.S. Holder for more than 60 days during the 121-day period beginning 60 days before the date that the relevant share or ADS becomes ex-dividend with respect to such dividend. Dividends that are not eligible for the treatment described above (including dividends received when we are a passive foreign investment company, as described below) generally will be taxable to U.S. Holders as ordinary income, and the special tax consequences described below may apply to such dividends. Distributions in excess of earnings and profits will be applied against and will reduce a U.S. Holder’s adjusted tax basis in our ordinary shares or ADSs and, to the extent in excess of such basis, will be treated as capital gain. Distributions generally will not be eligible for the dividends received deduction allowed to U.S. corporations.

      Distributions of current or accumulated earnings and profits paid in a foreign currency to a U.S. Holder will generally be includible in the income of a U.S. Holder in a U.S. dollar amount calculated by reference to the exchange rate on the date the distributions are received (or treated as received). A U.S. Holder who receives a foreign currency distribution and converts the foreign currency into U.S. dollars subsequent to receipt will have exchange gain or loss based on any appreciation or depreciation in the value of the foreign currency against the U.S. dollar, which generally will be U.S. source ordinary income or loss.

      U.S. Holders who are able, under Irish domestic tax legislation, to claim a refund or exemption of Irish tax withheld should not expect to obtain a credit against U.S. federal income tax liability for that withheld tax. For more information, please see “Irish Tax Consequences.”

      Because the tax rules that apply to the availability or use of foreign tax credits and deductions for foreign taxes are complex, U.S. Holders should consult with, and rely solely upon, their personal tax advisors with respect to such matters.

Sale, Exchange or Other Disposition

      Subject to the discussion below under “Passive Foreign Investment Company,” a U.S. Holder generally will recognize capital gain or loss for U.S. federal income tax purposes upon the sale or other disposition of ordinary shares or ADSs evidenced by ADRs in an amount equal to the difference between the amount realized on the sale or other disposition and the U.S. Holder’s adjusted tax basis in his, her or its ordinary shares or ADSs. The capital gain or loss recognized on such sale or other disposition will be long-term capital gain or loss if the ordinary shares or ADSs have been held for more than one year at the

-59-

time of sale or other disposition. In the case of individuals, long-term capital gains are generally taxed at a maximum rate of 15%. The deductibility of capital losses is subject to limitations. In general, any gain or loss recognized by a U.S. Holder on the sale or other disposition of ordinary shares or ADSs will be U.S. source income or loss for foreign tax credit purposes.

Passive Foreign Investment Company

      In general, a foreign corporation may be classified as a passive foreign investment company for U.S. federal income tax purposes if:

• 75% or more of its gross income in a taxable year falls within specific categories of passive income; or

• the average percentage of its assets in a taxable year (ordinarily determined based on their market value) which produce passive income or are held for the production of passive income is at least 50%.

      If we were classified as a passive foreign investment company, and a U.S. Holder did not make a qualifying election either to treat us as a “qualified electing fund” or to mark our ordinary shares or ADSs to market, as described below:

• Excess distributions by us to a U.S. Holder would be taxed in a special way. “Excess distributions” are amounts received by a U.S. Holder with respect to our ordinary shares or ADSs in any taxable year that exceed 125% of the average distributions received by such U.S. Holder from us in the shorter of either the three previous years or the U.S. Holder’s holding period for the ordinary shares or ADSs before the current taxable year. Excess distributions must be allocated ratably to each day that a U.S. Holder has held our ordinary shares or ADSs. A U.S. Holder would be required to include amounts allocated to the current taxable year and years before we became a passive foreign investment company as ordinary income. In addition, amounts allocated to each taxable year beginning with the year we first became a passive foreign investment company would be taxed at the highest rate in effect for that year on ordinary income and the tax would be subject to an interest charge at the rate applicable to deficiencies for income tax.

• The entire amount of gain that is realized by a U.S. Holder upon the sale or other disposition of our ordinary shares or ADSs evidenced by ADRs would also be considered an excess distribution and would be subject to tax as described above.

• The adjusted tax basis in our ordinary shares or ADSs evidenced by ADRs acquired from a decedent who was a U.S. Holder of the ordinary shares or ADSs would not be increased to equal the fair market value of such ordinary shares or ADSs as of the date of the decedent’s death but would instead be equal to the decedent’s adjusted tax basis, if lower. A U.S. Holder could not avoid this result by electing to mark our ordinary shares or ADSs to market.

      If a U.S. Holder has made a qualified electing fund election for all taxable years during which the U.S. Holder owned our ordinary shares or ADSs and we were a passive foreign investment company, the passive foreign investment company rules described above would not apply to the U.S. Holder. Instead, that U.S. Holder would be required to include in income for each taxable year a pro rata share of our ordinary earnings as ordinary income and a pro rata share of our net capital gain as long-term capital gain. The qualified electing fund election is made on a shareholder-by-shareholder basis and can be revoked only with the consent of the Internal Revenue Service. A U.S. Holder generally makes a qualified electing fund election by attaching a completed Internal Revenue Service Form 8621 to a timely filed U.S. federal income tax return. Even if a qualified electing fund election is not made, a shareholder in a passive foreign investment company who is a U.S. Holder must file a completed Internal Revenue Service Form 8621 every year.

-60-

      Alternatively, if a U.S. Holder is eligible to elect to mark our ordinary shares or ADSs evidenced by ADRs to market annually and makes a mark to market election, the following rules generally would apply for each of the U.S. Holder’s taxable years:

• if the fair market value of the U.S. Holder’s ordinary shares or ADSs exceeds the U.S. Holder’s adjusted tax basis in such ordinary shares or ADSs as of the close of the U.S. Holder’s taxable year, the U.S. Holder would recognize the amount of the excess as ordinary income;

• if the fair market value of the U.S. Holder’s ordinary shares or ADSs is less than the U.S. Holder’s adjusted tax basis in those ordinary shares or ADSs as of the close of the U.S. Holder’s taxable year, the U.S. Holder might recognize the amount of the difference as ordinary loss. Losses would be allowed only for the amount of net mark to market gain previously included by the U.S. Holder under the election for prior taxable years; and

• if the U.S. Holder has elected to mark our ordinary shares or ADSs to market for all taxable years during which the U.S. Holder owned our ordinary shares or ADSs and we were a passive foreign investment company, the “excess distribution” rules generally would not apply to the U.S. Holder.

      U.S. Holders who hold ordinary shares or ADSs evidenced by ADRs during a period when we are a passive foreign investment company will be subject to the preceding rules, even if we cease to be a passive foreign investment company, subject to exceptions for U.S. Holders who made a qualified electing fund election or mark to market election. U.S. Holders are urged to consult their tax advisors about the passive foreign investment company rules, including the specific rules and requirements applicable to making qualified electing fund and mark to market elections.

Status of IONA as a Passive Foreign Investment Company

      Passive foreign investment company status is determined as of the end of each taxable year and is dependent upon a number of factors, including the value of a corporation’s assets and the amount and character of its gross income. The determination of whether we are or will become a passive foreign investment company will be affected by how rapidly we use our cash and investment assets in our business. If the market price of our ordinary shares or ADSs is relatively low, we may be classified as a passive foreign investment company. Therefore, we cannot provide any assurance that we are not or will not become a passive foreign investment company.

Backup Withholding and Information Reporting

      Dividends on our ordinary shares or ADSs, and payments of the proceeds of a sale of our ordinary shares or ADSs, paid within the United States or through certain U.S. related financial intermediaries are subject to information reporting and may be subject to backup withholding at a current rate of 28% if a U.S. Holder fails to:

• furnish its taxpayer identification number (social security or employer identification number) and certify that such number is correct;

• certify that such U.S. Holder is not subject to backup withholding; or

• otherwise comply with the applicable requirements of the backup withholding rules.

      Any amounts withheld under the backup withholding rules from a payment to a U.S. Holder will be allowed as a credit against such U.S. Holder’s U.S. federal income tax and may entitle the U.S. Holder to a refund, provided that the required information is furnished to the IRS. U.S. Holders should consult their tax advisors regarding their qualification for exemption from backup withholding and the procedure for obtaining such an exemption if applicable.

Item 11. Quantitative and Qualitative Disclosures about Market Risk

     The following discussion regarding our market risk contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 that relate to future events or our future financial performance. In some cases, you can identify forward-looking statements by terminology, such as “may,” “will,” “should,” “could,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “predict,” “intend,” “potential,” or “continue” or the negative of such terms or other comparable terminology, although not all forward-looking statements contain such terms. These forward-looking statements are neither promises nor guarantees but rather are subject to a number of risks and uncertainties which could cause actual results to differ materially from those described in the forward-looking statements, including risks of exchange rate fluctuations, interest rate fluctuations and general market volatility, that could cause actual results to differ materially from those discussed in the forward-looking statements.

      Prior to 1999, we had undertaken transactions to hedge the risks associated with fluctuations in exchange rates of the Irish pound and the euro to the dollar. Because the majority of our sales and expenses are currently made in U.S. dollar, we no longer enter into foreign currency forward exchange contracts to manage exposure related to transactions denominated in foreign currencies. In the future, we may undertake transactions to hedge the risks associated with fluctuations in exchange rates if the risk from foreign currency exposure increases due to a decrease in the percentage of U.S. dollar-based transactions. Any market value gains or losses recognized on hedges of payables in the future will be offset against foreign exchange gains or losses on those payables. The gain or loss and premium or discount on forward contracts designated as hedges of firm commitments will be deferred until the hedged transaction is completed and included in the measurement of the value of the hedged transaction. At December 31, 2004, we had no foreign exchange contracts outstanding.

      Our trading portfolio of investments is not considered to be subject to material market (interest rate) risk because of the relatively short-term maturities of investments included in the portfolio.

      For further discussion of our market risk, please see Item 5.A. “Operating Results—Exposure to Currency Fluctuations.”

Item 15. Controls and Procedures

      Our Chief Executive Officer, Peter M. Zotto, and our Chief Financial Officer, Daniel Demmer, (our principal executive officer and principal financial officer, respectively) have concluded that our disclosure controls and procedures (as defined in U.S. Exchange Act Rule 13a-15(e)) were effective as of December 31, 2004 to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by IONA in such reports is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. During the fiscal year ended December 31, 2004, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Audit Committee’s Pre-approval Policies and Procedures

      Our Audit Committee has adopted a pre-approval policy for audit and non-audit services which sets forth the manner in which certain proposed services to be performed by our independent auditor may be pre-approved. Under the policy, the Audit Committee annually pre-approves a catalog of specific audit and non-audit services that may be performed by our auditors in the categories of Audit Services, Audit-Related Services, Tax Services and All Other Services. In addition, the policy sets forth an annual budget for each specific cataloged service that may not be exceeded without obtaining separate pre-approval from the Audit Committee. Our Chief Financial Officer receives all requests for independent auditor services that are pre-approved under the policy and must determine if each such request is pre-approved under the policy pursuant to the catalog.

      Pursuant to the policy, any proposed service not pre-approved under a catalog or any proposal exceeding the allotted budget must be submitted to the Audit Committee for approval at the next scheduled Audit Committee meeting. In the event that time constraints necessitate pre-approval prior to the Audit Committee’s next scheduled meeting, the Chairman of the Audit Committee will have the authority to grant such pre-approval pursuant to the policy.

      The Chief Financial Officer is responsible for monitoring the services of the independent auditor, periodically reporting the monitoring results and determining whether such services are in compliance with the policy. The Chief Financial Officer and any member of management are required under the policy to immediately report any breach of the policy to the Chairman of the Audit Committee.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

IONA Technologies PLC

      We have audited the accompanying consolidated balance sheets of IONA Technologies PLC (the “Company”) as of December 31, 2004 and 2003, and the related consolidated statements of operations, changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2004. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

      We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

      In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of IONA Technologies PLC as of December 31, 2004 and 2003, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2004, in conformity with U.S. generally accepted accounting principles.

IONA TECHNOLOGIES PLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Summary of Significant Accounting Policies

Organization

      IONA Technologies PLC (“IONA”) is organized as a public limited company under the laws of Ireland. IONA Technologies PLC and its subsidiaries, all of which are wholly-owned (collectively, the “Company”), provide enterprise integration software. The Company also provides professional services, consisting of customer consulting and training and, to a limited extent, product customization and enhancement, as well as customer technical support. The Company’s major customers, based on revenues earned, are corporate information technology departments of U.S. businesses. The Company also earns significant revenues from similar customers in European countries and the rest of the world.

Basis of Presentation and Principles of Consolidation

      The accompanying Consolidated Financial Statements are prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”). The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying footnotes. Actual results could differ from those estimates.

      The accompanying Consolidated Financial Statements include IONA and its wholly-owned subsidiaries in the United States, British West Indies, Europe, Australia, Japan, China, Canada, Singapore and Korea after eliminating all material intercompany accounts and transactions.

Companies Acts, 1963 to 2003

      The financial information relating to IONA and its subsidiaries included in this document does not comprise full group accounts as referred to in Regulation 40 of the European Communities (Companies: Group Accounts) Regulations 1992, copies of which are required by that Act to be annexed to a Company’s annual return. The auditors have made reports without qualification under Section 193 of the Companies Act, 1990 in respect of the Consolidated Financial Statements for the years ended December 31, 2003 and 2002. Copies of the Consolidated Financial Statements for each of the years ended December 31, 2003 and 2002 have been so annexed to the relevant annual returns, and a copy of the Consolidated Financial Statements for the year ended December 31, 2004 together with the report of the auditors thereon will in due course be annexed to the relevant annual return, which will be filed after the annual general meeting of IONA in 2005.

Foreign Currency Translation

      The U.S. dollar is the functional currency for the Company. In accordance with Statement of Financial Accounting Standards No. 52, “Foreign Currency Translation” (“SFAS 52”), assets and liabilities denominated in foreign currencies are translated at year end exchange rates while revenues and expenses are translated at rates approximating those ruling at the dates of the related transactions. Resulting gains and losses are included in net income (loss) for the year.

Revenue Recognition

      The Company’s revenue is derived from product license fees and charges for services. The Company follows the revenue recognition criteria of Statement of Position 97-2, “Software Revenue Recognition,” as amended by SOP 98-4 and SOP 98-9 issued by the Accounting Standards Executive Committee of the American Institute of Certified Public Accountants and related interpretations (collectively, “SOP 97-2”). Under the terms of SOP 97-2 where an arrangement to deliver software does not require significant

F-6

IONA TECHNOLOGIES PLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

production, modification or customization, the Company recognizes software revenues when all of the following criteria are met:

•  persuasive evidence of an arrangement exists;

•  delivery has occurred;

•  fee is fixed or determinable; and

•  collectibility is probable.

      For arrangements with multiple elements, the Company allocates revenue to each element of a transaction based upon its fair value as determined by “vendor specific objective evidence.” Vendor specific objective evidence of fair value for each element of an arrangement is based upon the normal pricing and discounting practices for each element when sold separately, including the renewal rate for support services. If the Company cannot objectively determine the fair value of any undelivered element included in the multiple element arrangement, the Company defers revenue until all elements are delivered, services have been performed, or until fair value can be objectively determined. When the fair value of a delivered element cannot be established, the Company uses the residual method to record license revenue, provided the fair value of all undelivered elements is determinable. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is allocated to the delivered elements and is recognized as revenue.

      The Company assesses whether fees are fixed or determinable at the time of sale and recognizes revenue if all other revenue recognition requirements are met. The Company’s standard payment terms are net 30; however, terms may vary based on the country in which the agreement is executed. Payments that extend beyond 30 days from the contract date but that are due within twelve months are generally deemed to be fixed or determinable based on the Company’s successful collection history on such arrangements, and thereby satisfy the required criteria for revenue recognition.

      Revenue for consulting services is generally recognized as the services are performed. Revenue from royalty arrangements in excess of guaranteed amounts are recognized upon notification of such royalties payable by the customer.

Allowances for Doubtful Accounts

      The Company makes judgments on its ability to collect outstanding receivables and provide allowances for the portion of receivables when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding receivables. In determining the provision, the Company analyzes the historical collection experience and current economic trends. The following is a summary of the allowance for doubtful accounts for the periods indicated (in thousands):

		Balance at						Balance at
		Beginning of						End of
		Period		Additions		Deduction (A)		Period
Year ended December 31, 2004

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Cost of Revenue

      Cost of revenue includes the costs of products and services. Cost of product revenue includes shipping, handling, materials (such as diskettes, packaging and documentation) and the portion of development costs associated with product development arrangements. Cost of service revenue includes the salary costs for personnel engaged in consultancy, training and customer support, and telephone and other support costs.

Cash Equivalents

      The Company considers all highly liquid investments with insignificant interest rate risk and purchased with a maturity of three months or less to be cash equivalents.

Marketable Securities

      Marketable securities consist of commercial paper, corporate bonds, and U.S. government agency fixed income securities. Marketable securities are stated at market value, and by policy, IONA invests primarily in high grade marketable securities to reduce risk of loss. All marketable securities are defined as trading securities under the provisions of Statement of Financial Accounting Standards No. 115, “Accounting for Certain Investments in Debt and Equity Securities” (“SFAS 115”), and unrealized holding gains and losses are reflected in the Consolidated Statements of Operations.

Research and Development

      Research and development expenditures are generally charged to operations as incurred. Statement of Financial Accounting Standards No. 86, “Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed” (“SFAS 86”), requires capitalization of certain software development costs subsequent to the establishment of technological feasibility. Based on the Company’s product development process, technological feasibility is established upon completion of a working model. Development costs incurred by the Company between completion of the working model and the point at which the product is ready for general release have been insignificant.

Goodwill

      Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in various business acquisitions as described in Note 3 and Note 10, and until January 1, 2002 was amortized on a straight line-basis over four years. Under Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”), goodwill acquired in a business combination on or after July 1, 2001 is not amortized. SFAS No. 142 requires goodwill to be tested at least annually for impairment or between annual tests in certain circumstances and written down when impaired. In October 2002, and as described in Note 10, the Company completed its annual impairment test and assessment of the carrying value of goodwill as required by SFAS 142. As a result of unfavorable market conditions and a decline in IONA’s market capitalization, this assessment resulted in a non-cash impairment charge of $276,808,000, equivalent to the carrying value of goodwill at October 1, 2002.

      In October 2004, the Company received $600,000 from its insurers in connection with the favorable resolution of an acquisition contingency, relating to litigation costs, which resulted in the recognition of $600,000 of income.

IONA TECHNOLOGIES PLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Other Non-Current Assets

      Other non-current assets represent costs of technology purchased or acquired on acquisitions, which have reached technological feasibility. The costs of technology have been capitalized and will be written off over their useful economic life estimated between three and four years in accordance with SFAS 86.

      In accordance with Statement of Financial Accounting Standards No. 144, “Accounting for Impairment of Long-Lived Assets”, the Company is required to test their other non-current assets for impairment whenever events or circumstances indicate that the value of the assets may be impaired. Factors the Company considers important, which could trigger impairment include:

• significant underperformance relative to expected historical or projected future operating results;

• significant changes in the manner of the Company’s use of the acquired assets or the strategy for our overall business;

• significant negative industry or economic trends;

• significant decline in the Company’s stock price for a sustained period; and

• significant decline in the Company’s market capitalization relative to net book value.

      Where events and circumstances are present which indicate that the carrying value may not be recoverable, the Company recognizes an impairment loss. In October 2003 and 2002, the Company identified indicators of impairment and its assessment resulted in a non-cash impairment charge of $80,000 and $28,586,000 in 2003 and 2002, respectively, representing the amount by which the carrying value exceeded the fair value of purchased technologies.

      Amortization expense for other non-current assets which are amortizable in accordance with SFAS 142, was $578,000, $796,000 and $10,115,000 in 2004, 2003 and 2002, respectively.

Property and Equipment

      Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:

Computer equipment	3 years
Office equipment	5 years
Furniture and fixtures	3 to 10  years

      Depreciation expense was $2,482,000, $4,666,000 and $7,198,000 in 2004, 2003 and 2002, respectively.

      During the year ended December 31, 2003, the Company recorded a $3,191,000 charge for the impairment of fixed assets and related costs for fixed assets no longer in use, as a result of the restructuring activities in 2003.

      During the year ended December 31, 2002, the Company recorded a $3,750,000 charge for the impairment of fixed assets and related costs, of which $1,600,000 was primarily attributable to the implementation of a new sales force automation system that replaced an existing system. The remainder of $2,150,000 related to fixed assets no longer in use in 2002, resulting in a reduction of their net book value to nil.

Software Development Costs

      The Company capitalizes certain software development costs associated with the development of the Company’s website and other internal financial software. These costs incurred are accounted for in accordance with Statement of Position 98-1, “Accounting for the Costs of Computer Software Developed

or Obtained for Internal Use” (“SOP 98-1”). In accordance with SOP 98-1, internal and external costs incurred to develop internal-use computer software during the application development stage are capitalized. Application development stage costs generally include software configuration, coding, installation and testing. Costs incurred for maintenance, testing minor upgrades and enhancements are expensed as incurred. Capitalized internal-use software development costs are included in fixed assets, and are amortized on a straight-line basis over the estimated useful lives of the related software, typically 3 years.

      The Company capitalized approximately $13,000 and $189,000 of software development costs during 2004 and 2003, respectively. Amortization associated with capitalized software development costs totaled approximately $353,000, $544,000, and $1,123,000 during 2004, 2003 and 2002, respectively.

Concentration of Credit Risk

      The Company sells its products to companies in various industries throughout the world and maintains reserves for potential credit losses. To date such losses have been within management’s expectations. The Company had an allowance for doubtful accounts of approximately $1,073,000 and $1,093,000 at December 31, 2004 and 2003, respectively. The Company generally requires no collateral from its customers. No customer accounted for more than ten percent of our total revenue in 2004, 2003 or 2002.

      The Company invests its excess cash in low-risk, short-term deposit accounts with high credit-quality banks in the United States, British West Indies and Ireland. At December 31, 2004, $31,324,000 was invested in marketable securities held for trading purposes, comprised of $8,154,000 in commercial paper, $3,912,000 in corporate bonds and $19,258,000 in U.S. government agency securities, under the management of two financial institutions. The Company performs periodic evaluations of the relative credit standing of all of the financial institutions with which it deals and considers the related credit risk to be minimal.

Compensated Absences

      The Company does not accrue for the liability associated with employees’ absences from employment because of illness, holiday, vacation or other reasons as the amount of compensation is not reasonably estimable.

Accounting for Income Taxes

      The Company uses the asset and liability method in accounting for income taxes in accordance with Statement of Financial Accounting Standards No. 109 “Accounting for Income Taxes” (“SFAS 109”). Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws which will be in effect when the differences are expected to reverse.

Stock-Based Compensation

      At December 31, 2004, the Company has five stock-based employee compensation plans, which are more fully described in Note 13.

      The Company has elected to follow Accounting Principles Board Opinion No. 25 “Accounting for Stock Issued to Employees” and related interpretations (collectively, “APB 25”) in accounting for its employee stock options. Accordingly, compensation cost for stock options is measured as the excess, if any, of the fair market value of IONA’s shares at the date of the grant over the amount an employee must pay to acquire the shares. This cost is deferred and charged to expense ratably over the vesting period (generally four years).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

      Where shares are issued at less than fair market value, the excess of the fair market value over the amount the employee must pay to acquire the shares is charged to expense as stock-based compensation and credited to additional paid-in capital in the period of transfer.

      Pro forma information regarding net income (loss) and net income (loss) per share is required by SFAS 123 and has been determined as if the Company had accounted for its stock options under the fair value method of SFAS 123. The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions:

	2004				2003			2002
Risk-free interest rate		4.00	%			4.25	%		4.00	%
Expected dividend yield		—				—			—
Expected volatility		0.861 to 0.999		��		0.885 to 1.102			1.150
Expected life (years)		3.5 to 4				5			5

      The fair value for rights to purchase awards under the 1999 Employee Share Purchase Plan was estimated at the date of grant using the following weighted-average assumptions:

	2004			2003			2002
Risk-free interest rate		2	%		2	%		2	%
Expected dividend yield		—			—			—
Expected volatility		0.886 to 0.999			1.060 to 1.102			1.150
Expected life		6 months			6 months			6  months

(“Netfish”), for total consideration of 5,036,318 newly-issued Ordinary Shares and replacement options, and $30,885,000 of closing costs incurred in connection with the merger. The portion of the total

intrinsic value, measured at the consummation date, of replacement unvested options granted by IONA in exchange for outstanding unvested options held by Netfish employees, that the future vesting period bears to the total vesting period ($10,380,000) was, in accordance with the requirements of FASB Interpretation No. 44 “Accounting for Certain Transactions Involving Stock Compensation”, accounted for as deferred stock-based compensation and is charged to expense as stock compensation ratably over the remaining vesting period of each tranche of unvested options. During the years ended December 31, 2004, 2003 and 2002, the Company reversed $41,000, $146,000 and $3,168,000, respectively, of deferred stock-based compensation related to the unvested replacement options of terminated Netfish employees and unvested replacement options accepted for exchange under the Exchange Offer, as described in Note 13. Stock compensation expense recognized for vested options of Netfish Employees was $38,000, $199,000 and $1,230,000 for the years ended December 31, 2004, 2003 and 2002, respectively.

      Stock compensation expense of $38,000, $199,000 and $1,230,000 for the periods ended December 31, 2004, 2003 and 2002, respectively can be attributed to the following line items in the Consolidated Statement of Operations:

Defined Contribution Plan

      The Company sponsors and contributes to a defined contribution plan for certain employees and directors. Contribution amounts by the Company are determined by management and allocated to employees on a pro rata basis based on employees’ contributions. The Company contributed approximately $1,066,000, $1,433,000 and $1,888,000 to the plan in the years ended December 31, 2004, 2003 and 2002, respectively. The decrease in Company contributions is due to a reduction in workforce as a result of restructuring plans in 2004, 2003 and 2002.

Advertising and Promotion Expense

      All costs associated with advertising and promoting products are expensed as incurred. Advertising and promotion expense was $2,092,000, $2,013,000 and $6,272,000 for the years ended December 31, 2004, 2003 and 2002, respectively.

Accounting Pronouncements

      In December 2004, and as amended in April 2005, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123R Share-Based Payment(SFAS 123R), which replaces SFAS 123 and supersedes APB Opinion No. 25. SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The pro forma disclosures previously permitted under SFAS 123 no longer will be an alternative to financial statement recognition. SFAS 123R is effective for fiscal years beginning after

F-12

IONA TECHNOLOGIES PLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

June 15, 2005. Early application of SFAS 123R is encouraged, but not required. The Company plans to adopt SFAS 123R on January 1, 2006.

      Public companies are required to adopt the new standard using a modified prospective method and may elect to restate prior periods using the modified retrospective method. Under the modified prospective method, companies are required to record compensation cost for new and modified awards over the related vesting period of such awards prospectively and record compensation cost prospectively for the unvested portion, at the date of adoption, of previously issued and outstanding awards over the remaining vesting period of such awards. No change to prior periods presented is permitted under the modified prospective method. Under the modified retrospective method, companies record compensation costs for prior periods retroactively through restatement of such periods using the exact pro forma amounts disclosed in the companies’ footnotes. Also, in the period of adoption and after, companies record compensation cost based on the modified prospective method. The Company has not yet determined the method of adoption it will use. The Company has not completed its evaluation of the effects of adopting SFAS 123R.

closing costs incurred in connection with the merger. Of the 4,221,216 newly-issued Ordinary Shares, 504,598 were held back by the Company in 2001 as a source of indemnification payments that may become due to the Company. If the Company made no claims for indemnification, 75% of the 504,598 Ordinary Shares, or 378,448 shares, would have been distributed to the former holders of Netfish shares in May 2002 and 25% of the 504,598 Ordinary Shares, or 126,150 shares, would be distributed in May 2003. In May 2002, the Company held back 142,045 Ordinary Shares to cover indemnification claims made by the Company. In May 2003, an additional 126,150 ordinary shares were held back to cover the indemnification claims that the Company previously made. If pending indemnification claims are resolved in a manner unfavorable to the Company, up to 268,195 Ordinary Shares held back by the Company could be distributed to the former holders of Netfish shares.

Object-Oriented Concepts, Inc.

      In February 2001, a wholly-owned subsidiary of IONA merged with and into Object-Oriented Concepts, Inc., a Delaware corporation (“OOC”), pursuant to which OOC became a wholly-owned subsidiary of IONA resulting in the issuance of 908,584 newly-issued Ordinary Shares and replacement options and the payment of $3,000,000 in cash. Of the 730,453 newly issued Ordinary Shares, 262,129 were subject to return to the Company as a purchase price adjustment upon the failure to achieve certain performance targets. In 2001, 174,735 ordinary shares no longer subject to return were recorded as additional purchase price based on fair market value at the time the performance targets were achieved.

      In February 2002, the performance targets applicable to the remaining 87,394 newly-issued Ordinary Shares issued in connection with the acquisition of OOC and subject to return were achieved. Accordingly, the Company allocated $1,219,000 of additional purchase price to goodwill, representing the fair market value of 87,394 Ordinary Shares no longer subject to return, at the time these performance targets were achieved.

      Details of impairment of goodwill are contained in Note 10.

4. Restructuring

      During 2004, 2003 and 2002, the Company’s management and board of directors approved restructuring plans, which included consolidation of excess facilities, a reduction in workforce, and other related costs. Total restructuring costs of $ nil, $20,525,000 and $20,763,000 were recorded related to these initiatives in 2004, 2003 and 2002, respectively. The restructuring charges in 2002 were accounted for in accordance with EITF 94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity.” The restructuring charge recorded in 2004 and 2003 were accounted for in accordance with SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities.”

      During 2004, the Company recorded a charge of $560,000 for severance and benefit costs related to cost reduction actions for eight sales employees. Also during 2004, the Company released $560,000 of restructuring accruals related to severance and benefit costs from previous restructurings, based on the final payments for such severance and benefits.

      Cash outlays associated with the restructuring plans initiated in 2004, 2003, 2002 and previous periods totaled approximately $5,972,000 during 2004, including approximately $2,503,000 in severance and related benefits paid to employees worldwide and $3,469,000 in facility closure costs.

      Amounts of restructuring costs remaining accrued at December 31, 2004 of $7,932,000 relate to remaining separation and facility closure and consolidation costs. The Company expects cash outlays of $5,517,000 will be made in the next twelve months, with the remaining cash outlays of $2,415,000 to be made through the end of 2013.

F-14

IONA TECHNOLOGIES PLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

      Although we do not anticipate additional significant changes to our restructuring accruals, the actual costs may differ from those recorded in the event that the subleasing assumptions require adjustment due to changes in economic conditions surrounding the real estate market or we terminate our lease obligations prior to the scheduled termination dates.

      The Company was required to make certain estimates and assumptions in assessing the amount accrued for excess facilities arising from these restructurings. The charge was calculated by taking into consideration (1) the committed annual rental charge associated with the vacant square footage, (2) an assessment of the sublet rents that could be achieved based on current market conditions, vacancy rates and future outlook, (3) an assessment of the period of time the facility would remain vacant before being sub-let, (4) an assessment of the percentage increases in the primary lease rent at each review, and (5) the application of a discount rate of 4% over the remaining period of the lease or break clause. The following sets forth our accrued restructuring costs as of December 31, 2004:

	Excess Facilities			Severance			Total

5. Restricted Cash

      At December 31, 2004, the Company has approximately $3,495,000 in restricted cash deposits with Citizens Bank which includes $495,000 of annual renewable letter of credit facilities for certain leased facilities and $3,000,000 payable upon demand for use towards satisfaction of amounts owed to a previous landlord. Should IONA not renew these letter of credit facilities or default on its rental obligations, $495,000 will be payable to the lessors. At December 31, 2003, the Company had approximately $3,745,000 in restricted cash deposits with Citizens Bank which included $745,000 of annual renewable letter of credit facilities for certain leased facilities and $3,000,000 payable upon demand for use towards satisfaction of amounts owed to a previous landlord.

	Total other non-current assets, net	$	441		$	940

10. Goodwill, Indefinite Lived Intangible, and Other Non-Current Assets

      Identifiable intangible assets comprise goodwill, which is not amortizable, and certain intangible other non-current assets, which are amortizable.

      In October 2002, the Company completed its annual impairment test and assessment of the carrying value of goodwill as required by SFAS 142. Goodwill was tested for impairment, by comparing the fair value of the Company, as calculated based on IONA’s market capitalization as of October 1, 2002, to the carrying value of the Company, and then comparing the implied fair value of goodwill to the carrying value at that date. As a result of unfavorable market conditions and a decline in IONA’s market capitalization, the Company recorded a non-cash impairment charge of $276,808,000, equivalent to the carrying value of goodwill, which reduced the carrying value of goodwill to nil.

      In October 2004, the Company received $600,000 from its insurers in connection with the favorable resolution of an acquisition contingency, relating to litigation, which resulted in the recognition of $600,000 of income.

      Other non-current asset amortization for the years ended December 31, 2004, 2003 and 2002 was $578,000, $796,000 and $10,115,000, respectively. Other non-current asset amortization is estimated to be approximately $232,000 in 2005, $50,000 in 2006 and $25,000 in 2007.

      Intangible assets are analyzed as follows:

		As of December 31,
		2004			2003
		(U.S. dollars in

Purchased Technology		$	3,429		$	3,373
Impairment Loss			—			(80	)
Accumulated Amortization			(3,122	)		(2,584	)
	Net	$	307		$	709

      In October 2002, and again in October 2003, in accordance with SFAS 142, the Company completed its assessment of the carrying value of purchased technologies and completed the relevant impairment tests as required by SFAS 144. Due to unfavorable market conditions and changes in the Company’s product strategy, it was determined that the carrying values of purchased technologies exceeded their fair value resulting in the Company recording a non-cash impairment charge of $80,000 and $28,586,000 in 2003 and 2002, respectively.

      The Company’s 2002 assessment included an independent analysis of the carrying values of purchased technologies, recorded in connection with the acquisitions of Object Oriented Concepts, Inc., Netfish Technologies, Inc. and the Sagavista application integration software of Software AG, Inc., including an initial comparison of the carrying value for each purchased technology to the future undiscounted cash flows associated with the technology. As a result of this analysis, it was determined due to the excess carrying value associated with each purchased technology that further impairment testing was required. The Company recorded non-cash impairment losses in October 2002, for the purchased technologies recorded in connection with the acquisitions of Object Oriented Concepts, Inc., Netfish Technologies, Inc., and the Sagavista application integration software of Software AG of approximately $4,461,000, $11,496,000 and $6,250,000, respectively. These impairment losses (reflected in the Consolidated Statements of Operations as impairment of intangible assets and fixed assets) represent the amount by which the carrying value of each purchased technology exceeded its estimated fair value, calculated by discounting future cash flows for each purchased technology to a present value using a rate of return which reflected the relative risk of the investment and the time value of money. In addition, as a result of changes in product strategy in reaction to market conditions, which resulted in changes to the Company product suite and the elimination of certain other purchased technologies from the Company product suite, an impairment loss, equivalent to the carrying values of these purchased technologies, of approximately $80,000 and $6,379,000 was recorded in 2003 and 2002, respectively.

12. Redeemable Preference Shares and Shareholders’ Equity

      IONA’s authorized share capital is divided into Redeemable Preference Shares (“Preference Shares”) of€0.0025 par value per share and Ordinary Shares of€0.0025 par value per share.

      The Preference Shares confer on the holders thereof the right to receive notice of and to attend all general meetings of IONA but not the right to vote on any resolution proposed therefor. They confer on the holders thereof the right to be paid out of the profits available for distribution, in priority to any payment of dividend on any other class of shares in IONA, a fixed cumulative preference dividend at a rate of 6% per annum on the amount paid up on the Preference Shares. Upon winding up of IONA, the Preference Shares confer upon the holders thereof the right to repayment of the capital paid thereon, together with payment of all arrears of preferential dividend, whether declared or not, to the date of redemption of the Preference Shares in priority to payment of any dividend or repayment of capital to the holders of the Ordinary Shares in the capital of IONA. Such Preference Shares do not, however, confer upon the holders thereof any further rights to participate in the assets of IONA.

      Dividends may only be declared and paid out of profits available for distribution determined in accordance with generally accepted accounting principles in Ireland and applicable Irish Company Law. Any dividends on the Ordinary Shares, if and when declared, will be declared and paid in U.S. dollars. The amount of retained earnings available for distribution as dividends at December 31, 2004, 2003 and 2002, at the exchange rates in effect on those dates, was nil.

13. Share Option Scheme

      The Company has elected to follow Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”) and related interpretations in accounting for its stock options. Under APB 25, the Company has recognized compensation expense of $38,000, $199,000 and $1,230,000 during 2004, 2003 and 2002, respectively, for those instances in which the exercise prices of IONA’s stock options were less than the estimated market price of the underlying shares on the date of grant and for the stock compensation arising on the Netfish acquisition (Note 3).

      IONA’s Executive Share Option Scheme has authorized the grant of options to purchase up to an aggregate of 1,125,500 Ordinary Shares to personnel. All options granted have seven year terms and generally vest in equal installments on each of the first, second, third and fourth anniversaries of the date of grant. As of December 31, 2004, an aggregate of 13,170 ordinary shares remain issuable upon the exercise of options outstanding and options available for grant under the Executive Share Option Scheme.

      During 1997, IONA’s Board of Directors and shareholders approved the 1997 Share Option Scheme which provides for the grant of share options to employees, consultants, directors and officers of the Company. The 1997 Share Option Scheme initially provided for the issuance of up to 2,250,000 of IONA’s Ordinary Shares. In 1998, IONA’s Board of Directors and shareholders approved an amendment to the 1997 Share Option Scheme, providing for an increase in the number of Ordinary Shares that may be issued under the 1997 Share Option Scheme to an aggregate of 4,750,000. In 2000, IONA’s Board of Directors and shareholders approved an amendment to the 1997 Share Option Scheme, providing for an increase in the number of Ordinary Shares that may be issued under the 1997 Share Option Scheme to an aggregate of 8,900,000.

      In 2001, IONA’s Board of Directors and shareholders approved an amendment to the 1997 Share Option Scheme, providing for an increase in the number of shares that may be issued under the 1997 Share Option Scheme to an aggregate of 12,900,000. Options granted under the 1997 Share Option Scheme expire ten years from the date of grant or five years from the date of grant in the case of an incentive stock option granted to an employee holding more than 10% of the total combined voting power of IONA. As of December 31, 2004, an aggregate of 9,816,261 ordinary shares remain issuable upon the exercise of options outstanding and options available for grant under the 1997 Share Option Scheme.

      During 1997, IONA’s Board of Directors and shareholders also approved the 1997 Director Share Option Scheme which provides for the grant of options to purchase a maximum of 250,000 Ordinary Shares of IONA to non-employee directors of IONA. In July 2002, the Board of Directors and shareholders approved an amendment to the 1997 Director Share Option Scheme to increase the number of Ordinary Shares issuable under that scheme from 250,000 to 500,000 shares. As of December 31, 2004, an aggregate of 446,000 ordinary shares remain issuable upon the exercise of options outstanding and options available for grant under the 1997 Director Share Option Scheme.

      In the fourth quarter of 2002, the Company made an offer to its employees, including executive officers other than the Chief Executive Officer and Chief Operating Officer, to exchange their outstanding options to purchase IONA’s ordinary shares that had an exercise price of more than $3.00 per share. Eligible options included options granted under the 1997 Share Option Scheme, the Genesis Development Corporation 1997 Stock Option Plan, the Object-Oriented Concepts, Inc. Stock Option Plan and the Netfish Technologies, Inc. 1999 Stock Option Plan. In exchange for eligible options, employees received a commitment for new stock options to be granted under the 1997 Share Option Scheme on or after May 15, 2003. Only those participants in the option exchange who were employees of the Company on the date the new options were granted were eligible to receive the new grant. Participating executive officers were required to forfeit, without exchange, all options granted on or after April 16, 2002. A total of 4,815,444 options were accepted for exchange under the offer and accordingly were canceled in November 2002. An additional 869,150 options were canceled without exchange. The Company granted new options to purchase approximately 3,191,884 shares on May 15, 2003. The new options granted under the offer have an exercise price of $1.99, which represented the fair market value of IONA’s Ordinary Shares, as determined by the last reported sale price of IONA’s Ordinary Shares on the Nasdaq National Market on May 14, 2003.

      In 2003 and 2002, all outstanding stock options granted have been excluded from the calculation of the diluted net loss per share because all such securities were anti-dilutive. The total number of shares related to the outstanding options excluded from the calculations of diluted net loss per share were approximately 700,000 and 334,000 for the years ended December 31, 2003 and 2002, respectively.

      The effect on basic and diluted net income (loss) per Ordinary Share and per ADS of the Irish manufacturing operations being taxed at a lower rate than the Irish Statutory income tax rate was approximately $ nil for the year ended December 31, 2004, an increase in net loss per share of $0.03 and $0.03 respectively for the year ended December 31, 2003 and an increase in net loss per share of $0.08 and $0.08 respectively for the year ended December 31, 2002.

	Related to preacquisition losses of Netfish		—			—		14,554
Balance at end of year		$	55,629		$	53,620	$	41,690

      At December 31, 2004 the Company has a net operating loss carryforward of approximately $107,500,000, including approximately $65,000,000 pre-acquisition losses from the Netfish acquisition, for U.S. federal and state income tax purposes which will expire in the tax years 2011 through 2024 if not previously utilized. Utilization of the U.S. net operating loss carryforward may be subject to an annual limitation due to the change in ownership rules provided by the Internal Revenue Code of 1986. This limitation and other restrictions provided by the Internal Revenue Code of 1986 may reduce the net operating loss carryforward such that it would not be available to offset future taxable income of the U.S. subsidiaries.

      At December 31, 2004 approximately $31,000,000 of the net operating loss carryforwards in the United States result from disqualifying dispositions. The tax value of the disqualifying dispositions has not been recognized in the tax reconciliation note as the utilization of the net operating loss carryforwards will result in an increase in Additional Paid-In Capital and not a reduction in Provision for Income Taxes. At December 31, 2004, $12,560,000 of the valuation allowance related to disqualifying dispositions.

      At December 31, 2004 the Company also had net operating loss carryforwards totaling approximately $117,600,000 for Irish income tax purposes which carry forward indefinitely.

      At December 31, 2004 the Company also had net operating loss carryforwards totaling approximately $2,900,000 for Australian income tax purposes which carry forward indefinitely.

      The utilization of these net operating loss carryforwards is limited to the future profitable operation of the Company in the related tax jurisdictions in which such carryforwards arose. Valuation allowances of 100% have been provided against the net operating loss carryforwards because of the history of operating losses in the related tax jurisdictions.

      Significant judgment is required in determining the Company’s worldwide income tax expense provision. In the ordinary course of a global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of income sharing and cost reimbursement arrangements among related entities, the process of identifying items of income and expense that qualify for preferential tax treatment and segregation of foreign and domestic income and expense to avoid double taxation. The Company has reserves for taxes that may become payable in future periods as a result of tax audits. It is the Company’s policy to establish reserves for taxes that may become payable in future years as a result of examination by tax authorities. The tax reserves are analyzed at each balance sheet date and adjustments are made as events occur to warrant adjustment to the reserves. At any given time the Company may be undergoing tax audits in several jurisdictions and covering multiple years. The tax reserve is the Company’s best estimate of the potential liability for tax contingencies. Inherent uncertainties exist in estimates of tax contingencies due to changes in tax law, both legislated and concluded through the various jurisdictions’ court systems. It is the opinion of the

F-24

IONA TECHNOLOGIES PLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Company’s management that the possibility is remote that costs in excess of those accrued will have a material adverse impact on the Company’s consolidated financial statements. The Company expects the completion of certain of these tax audits in the near term. However, based on the currently available information, the Company is not able, at this time, to determine if it is reasonably possible that the final outcome of tax examinations will result in a materially different outcome than assumed in its tax reserves.

17. Industry and Geographic Information

      Statement of Financial Accounting Standards No. 131, “Disclosures about Segments of an Enterprise and Related Information” (“SFAS 131”), established standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company has one reportable segment: enterprise infrastructure software. The Company also provides professional services, consisting of consulting and training, customer support of all its products, and, to a limited extent, product customization and enhancements.

      The accounting policies of the reportable segment are the same as those described in the summary of significant accounting policies.

consulting services to IONA. The consulting arrangement was terminated in October 2003, prior to Mr. Zotto being hired as IONA’s Chief Operating Officer. The Company paid Claright fees of approximately $101,750 for such services.

      In July 2003, we engaged K Capital Source Limited (K Capital) to provide us with capital market communication and advisory services. Mark Kenny, a principal of K Capital, is the son of one of our directors, Dr. Ivor Kenny. Under our agreement with K Capital, we pay $40,000 per fiscal quarter for such services. No amounts relating to services rendered were outstanding as of December 31, 2004.
