D.  Risk Factors

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

   A decline in the demand for information technology (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.
An 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.

   In addition, the September 11, 2001 terrorist attacks in the United States,
related military actions, events or effects occurring in response to those
developments, and general economic and industry conditions may reduce the
amount or delay the timing of capital expenditures by corporations for IT. Our
product revenue for the third and fourth quarters of 2001 were lower than the
comparable quarters of 2000, and our service revenue increased slightly on a
sequential, quarter-to-quarter basis during 2001. Accordingly, we cannot assure
you 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 revenues because
our prospective customers often take significant time evaluating our products
before licensing them. The period between initial customer contact and purchase
by a customer may range up to twelve months. 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 application and Web services integration software;

  .   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.

                                      -3-



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. 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;

  .   customers may unexpectedly postpone or cancel 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.

   Historically, our revenues have been seasonal, primarily in the first
quarter of each year. Because of this seasonality, as well as continued
uncertainty associated with levels of IT investments, we anticipate that, as in
previous years, our revenues in the first quarter of 2002 will be below those
experienced in the fourth quarter of 2001.

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 in part to costs associated
with the development and introduction of new products and services, charges
associated with acquisitions, and certain nonrecurring expenses attributable to
the settlement of litigation. 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 solutions.

   We believe that there is an emerging demand for Web services. Therefore, we
have invested significant amounts in developing and introducing products to
meet the development, deployment and integration requirements of enterprises
implementing Web services. If the market for Web services infrastructure
solutions 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.

                                      -4-



   The acceptance of our recently launched Orbix E2A Web Services Integration
Platform also depends upon the development and proliferation of Web services
standards for application integration. If these standards do not continue to
develop or gain widespread acceptance, 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.

   In November 2001, we announced our Orbix E2A Application Server Platform and
our Orbix E2A Web Services Integration Platform. 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.

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

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 intend to 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.

We may be required to delay revenue recognition into 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;

                                      -5-



  .   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 extend our sales cycles
and adversely affect our quarterly or annual operating results.

   We derive an increasing and 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.

A deterioration in our relationship with software vendors, systems 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, 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 systems
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 systems 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.

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

   Our rapid growth could place a significant strain on our management,
operating procedures, financial resources, information systems, employees and
facilities. To manage our expanded operations, we will need to upgrade
continuously our operating, accounting, reporting and information systems, and
we will also need to integrate the systems of any acquired entity. If we
experience delays or difficulties in upgrading or integrating our systems, 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 manage changing business
conditions and expanded operations and to implement and improve our
operational, financial control, reporting and information systems.

                                      -6-



   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.

We operate in a highly competitive market and we may be unable to compete
successfully against larger companies with greater resources.

   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;

  .   cross-enterprise integration software; and

  .   enterprise application servers.

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

  .   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;
      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.
Moreover, 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.

                                      -7-



We derive substantially all of our revenue from a limited number of our
products.

   To date, we have derived substantially all of our revenue from the licensing
of our products that currently compose our Orbix E2A Application Server
Platform and fees from related services. We expect these products and our Orbix
E2A Application Server Platform to 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, system integrators and other third parties. We plan to
continue to invest in, and rely on sales through, these distribution 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.

If we are unable to hire 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. Our future success will also depend upon our continuing ability to
recruit, retain and assimilate technical, sales and marketing personnel. 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 we intend 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;

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

  .   failure to enter into relationships with local resellers, systems
      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.

                                      -8-



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, tax rates in Ireland on trading income
are 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 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.

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 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 or inadequate protection 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 in our products, we
may have to stop shipping products and incur significant development or license
expenses.

   We 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 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.

                                      -9-



   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 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

  .   reimburse customers under certain indemnification 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 or adverse or protracted litigation arises out of any such
assertion, our business, financial condition or results of operations could be
materially adversely affected.

million, respectively, for the purchase of furniture, fixtures and equipment,
for further investment in our management information systems and for capital
expenditures relating to increased employee headcount.

   During 2001, 2000 and 1999 we invested $15.5 million, $8.8 million and $1.8
million, respectively, in technology, which had reached technological
feasibility.

B.  Business Overview

Overview

   We provide software that enables our customers to develop, deploy, integrate
and manage applications within the enterprise and across the firewall to the
extended enterprise. Our comprehensive, standards-based products enable our
customers to build, maintain and scale their disparate computing environments
while preserving and extending existing information technology investments. Our
products are designed to enable the rapid alignment of evolving business
processes with distributed information technology systems to reach customers,
partners, suppliers and employees, which we refer to as "End 2 Anywhere(TM)" or
"E2A(TM)". We offer professional services including ongoing customer support
and maintenance as well as high-level design consultation, developer education
and product implementation.

   Founded in 1991, we are headquartered in Dublin, Ireland, with our
wholly-owned U.S. subsidiary headquartered in Waltham, Massachusetts. We have a
long track record of technology leadership and dedication to continuous product
improvement. From our inception, we have focused on building software to
integrate distributed computing systems. 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 and employ more than 900 people in over 30
offices worldwide.

Industry Background

   A typical enterprise information technology infrastructure consists of
multiple databases, application servers, applications, integration tools and
portals that are often separately maintained and incompatible. The development
and integration of enterprise applications in light of evolving computing
requirements is highly complex. Moreover, demand for greater efficiency,
flexibility and ease of use in business operations has resulted in the
proliferation of applications that automate an enterprise's core processes.
Software vendors have developed numerous applications, based on different
programming languages, operating systems and hardware specifications, to
streamline business processes, such as telecommunications network management
systems, financial trading systems, supply chains and internal administrative
processes. To perform a single business transaction, numerous distinct
processes must be coordinated across several different applications and
systems. For example, when a customer order is submitted, Web-based front-end
systems need to communicate with supplier inventory systems to determine the
availability and location of the item; coordinate with financial institutions
to verify the customer's credit and process payment;

                                     -11-



synchronize shipment dates and track logistics with third-party systems; and
record the transaction in internal back- end systems. To facilitate performance
of these functions, various infrastructure vendors, including applications
server and enterprise integration software providers, have emerged to deploy,
integrate and manage disparate applications as well as connect legacy systems.

   The proliferation of integration solutions has created additional challenges
for software developers and vendors. Most solutions are proprietary in nature,
do not support cross-industry technological standards, and require significant
training and implementation. While these solutions address specific integration
challenges, they only connect one application to another, do not enable
multi-level, enterprise-wide integration across all applications and do not
provide the level of scalability required for critical enterprise applications.
As a result, enterprises are struggling with slow returns on their IT
investments, the complexity of existing integration challenges and the demands
of an increasingly dynamic business environment.

   Web services are emerging as the next architectural approach for the
integration of software applications and business processes utilizing the
infrastructure of the Internet. Through the use of open standards, Web services
allow applications to more easily share data and leverage functionalities of
other applications. As a result, Web services provide an opportunity to
implement and manage dynamic business processes in a less disruptive, less
costly and faster manner than in existing integration solutions. The deployment
and integration of applications within a Web services environment requires
software infrastructure to provide necessary quality of service and
functionality, such as reliability, scalability and security, as well as
integration with legacy applications. Due to the continued reliance on a

Strategy

   Our objective is to be the leading e-Business Platform provider of Web
services integration solutions. To achieve this objective, we intend to pursue
the following strategies:

   Maintain our Technological Leadership.  We have a long track record of
technology leadership and dedication to continuous product improvement. Our
comprehensive suite of infrastructure products enable our customers to rapidly
and efficiently develop, deploy, integrate and manage applications within the
enterprise and across the firewall to the extended enterprise. We intend to
further expand our core product functionality as well as continue to develop
complementary products that enhance our Orbix E2A software products. 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.

   Leverage and Expand our Strategic Alliances.  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. We intend to leverage our established
relationships and forge 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
relationships with leading software and technology vendors, such as Business
Objects, Compaq, Hewlett-Packard, Manugistics, VeriSign and VERITAS Software,
and global system integrators, such as CSC, PwC and SAIC. 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.

   Continued Focus on the Developer Community.  Historically, we have marketed
and sold our products both at the enterprise level and to technology
developers. Developers play a key role in deciding which technology solutions a
company surveys, tests, buys, builds or deploys. We believe that widespread
acceptance of our

                                     -13-



products in the developer community will create enterprise sales opportunities.
To address the needs of the developer community, we configure our products to
include required product functionality and provide flexible pricing structures.
We believe that this approach optimizes our ability to rapidly grow our user
community and increase our market presence beyond our enterprise customer base.

   Further Penetrate our Existing Customer Base.  We have a large and growing
customer base across a wide variety of industries. The strategic importance of
our products allows us to develop strong relationships with the key technology
decision makers within our customer base. In addition, our strategic selling
approach facilitates broad adoption of our products throughout a company.
Accordingly, we intend to generate incremental sales from our existing customer
base through the introduction of new and enhanced products.

Products

   Our Orbix E2A software has two components: the Application Server Platform
and the Web Services Integration Platform. These platforms can be used
together, deployed as independent components or integrated with a customer's
existing infrastructure. Their modular architecture provides our customers with
the flexibility to meet changing business and computing requirements. The
Application Server Platform enables the development, deployment and hosting of
new applications and supports industry standards, including J2EE and CORBA, and
integration with Microsoft's .NET as well as mainframe and legacy systems. Our
Web Services Integration Platform provides for the aggregation, coordination
and hosting of Web services by combining extensive EAI and B2Bi technologies
and integrated Web services standards, including XML, SOAP, WSDL and UDDI.

   Based on existing standards, Web services can significantly increase an
enterprise's flexibility and mitigate many of the adverse effects of
traditional application integration. Web services allow an enterprise to
integrate and customize its existing software applications, capitalize on
existing IT investments by extending the life of legacy applications, systems
and networks, and realize value by reducing the time and expense required to
integrate within the enterprise as well as with customers, partners, suppliers
and employees.

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. Our pending U.S. trademark applications cover, among others, the
terms "End 2 Anywhere(TM)" and "Orbix E2A(TM)".

   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 or inhibit unauthorized

registered

                                     -18-



intellectual property rights with respect to our software. We have a number of
U.S. and international patent applications pending. Because shrink-wrap
licenses are not signed by licensees, they may be unenforceable under the laws
of certain jurisdictions. In addition, the laws of 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, 2001, we or our wholly-owned subsidiaries had
approximately 907 full-time employees, with 533 based in the Americas, 313
based in Europe/Middle East/Africa and 61 based in Asia-Pacific. These
employees include 244 in product development and management, 70 in customer
engineering, 48 in marketing, 317 in sales, 106 in global services and 122 in
finance, legal, human resources, administration and information technology. 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 operation. We, however, have in the past
been and may in the future be subject to claims and litigation in the ordinary
course of business. In the event that any such claims or litigation are
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, tax rates in Ireland on trading income
are 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 capital 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

   Our business is not materially affected by seasonal factors. Our products
and services do not materially depend on the availability of raw materials.

                                     -19-

processes with distributed information technology systems to reach customers,
partners, suppliers and employees, which we refer to as "End 2 Anywhere(TM)" or
"E2A(TM)". We offer professional services including ongoing customer support
and maintenance as well as high-level design consultation, developer education
and product implementation.

   Our revenue is derived from product license fees and charges for support and
global 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. 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 earned.

   Our total revenue grew by 18.1% to $180.7 million in 2001 from $153.1
million in 2000 and by 45.2% to $153.1 million in 2000 from $105.4 million in
1999. Total revenue from customers located outside the United States was $61.0
million in 2001, $50.0 million in 2000 and $37.8 million in 1999. Total revenue
from customers located outside the United States accounted for approximately
33.8% of total revenue in 2001, 32.6% of total revenue in 2000 and 35.9% of
total revenue in 1999. No single customer accounted for more than 10% of total
revenue in 2001, 2000 or 1999.

   To date, we have derived substantially all of our revenue from the licensing
of our enterprise integration and application server software products that
currently compose our Orbix E2A Application Server Platform, and fees from
related services. We expect that our recently introduced products will
increasingly contribute to our revenue. We market our E2A software products,
consisting of our Orbix E2A Application Server Platform and Orbix E2A Web
Services Integration Platform, through our direct sales organization and
through 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 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 and higher
gross margins on direct sales than on sales through indirect channels.

   Our operating expenses, excluding stock compensation, in-process research
and development, amortization of goodwill and purchased intangible assets,
restructuring, write-off of assets, and settlement of litigation have increased
in absolute dollar amounts in each consecutive year from 1996 through 2001.
This trend reflects our rapid transition from concentrating primarily on
product development to marketing and licensing products, offering services and
developing our software. We intend to continue to increase expenditures in all
operating areas.

   We have significant operations and generate a substantial portion of our
taxable income in Ireland. In general, tax rates in Ireland on trading income
are 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 Recent 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. These ordinary shares will
be issued and distributed to the holders of the outstanding Netfish shares over
a two-year period from the date of merger, after adjusting for any
indemnification payments made. 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 acquisition based primarily on an
independent valuation, and to acquired in-process research and development for
which technological feasibility had not been established and for which
alternative future uses did not exist based on independent valuation.

   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. Some of these performance targets were achieved in 2001.
As a result, 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. As of March 1, 2002, the remaining 87,394
ordinary shares were no longer subject to return to us and were also 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 and hired a
substantial portion of the Software AG, Inc. engineering team responsible for
the development of the technology.

   In 2000, we acquired Genesis Development Corporation (Genesis). At the time
of acquisition, 176,156 ordinary shares were subject to return to us as a
purchase price adjustment upon the failure of Genesis to achieve certain
performance targets. The contingency was resolved in May 2001 and,
consequently, the ordinary shares no longer subject to return were recorded as
additional purchase price based on their fair market value at the time the
contingency was resolved.

Critical Accounting Policies and Estimates

   Our discussion and analysis of our financial condition and results of
operations are based upon our consolidated financial statements, which have
been prepared in accordance with accounting principles generally accepted in
the United States. The preparation of these financial statements requires us to
make estimates and judgments that affect the reported amounts of assets,
liabilities, revenue and expenses, and related disclosure of contingent assets
and liabilities.

   On an on-going basis, we evaluate our estimates, including those related to
bad debts, intangible assets, investments, foreign currency, income taxes,
restructuring, and contingencies and litigation. We base our estimates on
historical experience and on various other assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions.

   We believe the critical accounting policies described below affect our more
significant judgments and estimates used in the preparation of our consolidated
financial statements.

  Revenue Recognition

   We recognize the majority of our revenue pursuant to software license
agreements. Revenue from software license agreements is recognized when
persuasive evidence of an arrangement exists, delivery has occurred, the fee is
fixed or determinable and collection of the resulting receivable is reasonably
assured. Collection is assessed based on a number of factors, including past
transaction history with the customer and the credit-worthiness of the
customer. A signed license agreement, purchase order or a written contract is
used as evidence of an arrangement.

   We maintain allowances for doubtful accounts for estimated losses resulting
form the inability of our customers to make required payments. If the financial
condition of our customers were to deteriorate, resulting in an impairment of
their ability to make payments, additional allowances may be required.

   We generate a portion of our revenues and corresponding accounts receivable
through sales denominated in currencies other than the U.S. dollar.
Historically, the foreign currency gains and losses on these receivables have
not been significant, and we have determined that foreign currency derivative
products are generally not required to hedge our exposure. If there were a
significant decline in the euro exchange rate, the U.S. dollar equivalents we
would receive from our customers could be less than the reported amount.

  Marketable Securities

   We currently classify our marketable securities as trading securities.
Pursuant to Statement of Financial Accounting Standards No. 115, "Accounting
for Certain Investments in Debt and Equity Securities," these securities are
measured at fair market value in the financial statements with unrealized gains
or losses reflected in earnings. Future adverse changes in market conditions or
poor operating results of underlying investments could result in losses that
would be reflected in earnings.

  Impairment of Intangible Assets

   We assess the impairment of identifiable intangibles and related goodwill
whenever events or changes in circumstances indicate that the carrying value
may not be recoverable.

   Factors considered important, which could trigger an impairment review,
include the following:

  .   significant under performance relative to expected historical or
      projected future operating results;

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

                                     -23-



  .   significant negative industry or economic trends; and

  .   significant decline in our stock price for a sustained period; and our
      market capitalization relative to net book value.

   When we determine that the carrying value of intangibles, long-lived assets
and related goodwill may not be recoverable based upon the existence of one or
more indicators of impairment, any impairment is measured based on a projected
net discounted cash flow expected to result from the asset, including eventual
disposition.

   Following our adoption of Statement of Financial Accounting Standards No.
142, "Goodwill and Other Intangible Assets," on January 1, 2002, we will cease
to amortize goodwill. In lieu of amortization, we are required to perform an
initial impairment review of our goodwill in 2002 and an annual impairment
review thereafter. Based on current circumstances, we believe the application
of the new rules will not have a material impact on our consolidated financial
statements.

Taxation

   We have significant operations and generate a substantial portion of our
taxable income in Ireland. In general, tax rates in Ireland on trading income
are 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."

Year Ended December 31, 2001 Compared to Year Ended December 31, 2000

  Total Revenue

   Total revenue increased by 18.1% to $180.7 million in 2001 from $153.1
million in 2000. Total revenue from customers located outside the United States
represented 33.8% of total revenue in 2001 and 32.6% of total revenue in 2000,
or $61.0 million and $50.0 million, respectively.

   Product Revenue.  Product revenue increased by 12.0% to $118.2 million, or
65.4% of total revenue, in 2001 compared to $105.5 million, or 68.9% of total
revenue, in 2000. The increase in product revenue was primarily attributable to
our continued efforts to develop and market our product set and to expand our
enterprise sales capability, offset in part by a reduced demand for our
products in the third and fourth quarters of 2001 due to general economic
conditions and the events of September 11, 2001.

                                     -25-



   Service Revenue.  We provide global services, consisting of consulting and
training, customer 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, facsimile and customer on-site assistance as well as access
to certain product upgrades. Service revenue increased by 31.6% to $62.5
million, or 34.6% of total revenue, in 2001 from $47.5 million, or 31.1% of
total revenue, in 2000. The increase in service revenue was principally due to
the increase of our enterprise sales combined with increasing global service
and support revenues associated with a growing customer base.

  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 $3.2 million, resulting in a product
gross margin of 97.3%, in 2001 compared to $3.5 million, resulting in a product
gross margin of 96.7%, in 2000. The increase in product gross margin was
primarily attributable to shipping and material efficiencies, and lower
third-party royalty expenses.

   Cost of Service Revenue.   Cost of service revenue consists primarily of
personnel costs for consultancy, training, technical support, product
customization and enhancement, and related operating costs of computer
equipment and non-billable travel expenses. Cost of service revenue was $34.9
million, resulting in a service gross margin of 44.1%, in 2001 compared to
$26.5 million, resulting in a service gross margin of 44.3%, in 2000. The
decrease in service gross margin was primarily attributable to an increase in
service personnel to support our expanding customer base.

  Operating Expenses

   In-process research and development.  In connection with our acquisition of
Netfish, we recorded a $3.6 million charge, or 2.0% of total revenue, in 2001
to account for acquired in-process research and development, for which
technological feasibility had not been established and for which alternative
future uses did not exist.

   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 $40.3
million, or 22.3% of total revenue, in 2001 compared to $26.9 million, or 17.6%
of total revenue, in 2000. The increase in research and development expenses
both in dollar amount and as a percentage of total revenue was primarily the
result of an increase in personnel and the development of our Orbix E2A
software products. We expect our research and development expenses to increase
in dollar amount in future periods to continue our investment in current and
future technologies.

   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 $88.4 million, or 48.9% of total revenue, in 2001
compared to $63.7 million, or 41.6% of total revenue, in 2000. The increase in
sales and marketing expenses both in dollar amount and as a percentage of total
revenue was due to continuing investment in direct enterprise sales capability
as well as increased investment in marketing our product set. We expect that
sales and marketing will continue to increase in dollar amount in future
periods as we continue to expand our enterprise sales and marketing
capabilities, raise the awareness of our Orbix E2A software products and expand
our strategic alliances.

   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

                                     -26-



occupancy, telephone and other office supply costs), and related indirect
costs. General and administrative expenses also include professional fees and
depreciation. General and administrative expenses were $15.3 million, or 8.5%
of total revenue, in 2001 compared to $12.0 million, or 7.9% of total revenue,
in 2000. The increase in general and administrative expenses both in dollar
amount and as a percentage of total revenue was due primarily to the
integration of Netfish. We expect that general and administrative expenses will
increase in dollar amount in future periods to support our increased scale of
operations.

   Amortization of Goodwill and Purchased Intangible Assets.  Amortization of
goodwill and purchased intangible assets consists of the amortization of
intangible assets acquired by us and the amortization of goodwill from
acquisitions. Amortization of goodwill and purchased intangible assets was
$75.6 million, or 41.8% of total revenue, in 2001 compared to $7.8 million, or
5.1% of total revenue, in 2000. The increase in amortization of goodwill and
purchased intangible assets is attributable to the acquisitions of Netfish in
May 2001 and OOC in February 2001, as well as other acquisitions in 2000 and
2001.

   Beginning in the first quarter of 2002, we will apply the new rules on
accounting for goodwill and other intangible assets, in accordance with
Statements of Financial Accounting Standards, No. 141, "Business Combinations,"
and No. 142, "Goodwill and Other Intangible Assets." Under the new rules,
goodwill and intangible assets deemed to have indefinite lives will no longer
be amortized but will be subject to annual impairment tests in accordance with
these Statements. Other intangible assets will continue to be amortized over
their useful economic lives. We will perform the first of the required
impairment tests of goodwill and indefinite-lived intangible assets as of
January 1, 2002. Based on current circumstances, we believe the application of
the new rules will not have a material impact on our consolidated financial
statements.

   Restructuring.  In 2001, our management and board of directors approved
restructuring plans, which included initiatives to integrate the operations of
the recently acquired companies, consolidate duplicative facilities and reduce
overhead. Total accrued restructuring costs of $5.7 million were recorded.
Restructuring expenses consist of involuntary employee separation benefits
related to the reduction of approximately 195 employees worldwide and costs
associated with the closure and consolidation of office space principally in
the United States. In 2001, we substantially completed these restructuring
plans, resulting in payments of $3.7 million in severance and related benefits
to employees worldwide and approximately $700,000 in facility closure costs. At
December 31, 2001, $1.3 million related to additional facility closure and
consolidation costs remained to be paid, with cash outlays expected to be
completed by the end of 2004.

   Settlement of Litigation.  In March 2000, RSA Securities, Inc. (RSA) and the
Massachusetts Institute of Technology filed suit against us alleging that we
breached the terms of our patent license agreement with RSA. In June 2000, we
entered into a confidential settlement agreement with RSA to settle all
outstanding claims among the parties. Costs associated with the settlement of
this litigation amounted to $1.4 million. There were no costs associated with
the settlement of this litigation incurred in 2001, and we do not believe that
any additional payments will be due in connection with this settlement.

  Income (Loss) from Operations

   We generated an operating loss of $86.3 million, or 47.7% of total revenue,
in 2001 compared to an operating profit of $11.3 million, or 7.4% of total
revenue, in 2000. Operating income, as adjusted to eliminate stock
compensation, in-process research and development, amortization of goodwill and
purchased intangible assets, restructuring and settlement of litigation, would
have been approximately $300,000, or 0.1% of total revenue, in 2001 and $20.9
million, or 13.7% of total revenue, in 2000. The amount of operating income in
2001, adjusted to eliminate stock compensation, in-process research and
development, the amortization of goodwill and purchased intangible assets,
restructuring and settlement of litigation, reflects our consistent investment
in our direct enterprise sales capability, continued efforts to develop and
market our product set and the integration of Netfish, as well as general
economic conditions and more cautious IT spending in the second half of 2001.

                                     -27-



  Other Income, Net

   Interest income, net, primarily represents interest earned on cash and
investment balances. Interest income, net was $2.5 million in 2001 compared to
$4.1 million in 2000. The decrease in interest income, net was due primarily to
lower average balances held in these accounts as well as declining interest
rates during 2001.

   Net exchange loss was $468,000 in 2001 compared to $384,000 in 2000. The net
exchange loss for 2001 was primarily due to the strength of the dollar against
the Japanese yen.

   Gain on sale of investment and other income was $164,000 in 2001 compared to
$1.9 million in 2000. During 2000, we sold over 75% of our investment in a
publicly-owned company and sold the remaining shares in the first quarter of
2001.

  Income Taxes

   Income tax benefit was $568,000 in 2001 compared to income tax of $2.8
million in 2000. Deferred tax assets were not recognized in respect of the net
operating loss carryforwards in either year because realization was not
sufficiently assured.

   If tax authorities in jurisdictions other than Ireland were to challenge
successfully the manner in which profits are recognized within IONA or, more
generally, the jurisdiction in which income is subject to taxation, our
prevailing effective tax rate will increase and our cash flows and results of
operations could be materially adversely affected.

   At December 31, 2001, we had a net operating loss carryforward of
approximately $42.0 million for U.S. federal income tax purposes. At December
31, 2001, we had a net operating loss carryforward of approximately $2.0
million for Australian tax purposes, which carries forward indefinitely. At
December 31, 2000, we had a net operating loss carryforward of approximately
$24.5 million for U.S. federal income tax purposes. At December 31, 2000, we
had a net operating loss carryforward of approximately $1.9 million for
Australian tax purposes, which carries forward indefinitely.

Year Ended December 31, 2000 Compared to Year Ended December 31, 1999

  Total Revenue

   Total revenue increased by 45.2% to $153.1 million in 2000 from $105.4
million in 1999. Total revenue from customers located outside the United States
represented 32.6% of total revenue in 2000 and 35.9% of total revenue in 1999,
or $50.0 million and $37.8 million, respectively.

   Product Revenue.  Product revenue increased by 48.1% to $105.5 million in
2000 compared to $71.3 million in 1999. The increase in product revenue was
primarily attributable to our continued efforts to develop and market our
product set and the expansion of our enterprise sales capability.

   Service Revenue.  Service revenue increased by 39.1% to $47.5 million in
2000 from $34.2 million in 1999. The increase in service revenue was
principally due to the expansion of our enterprise sales capability combined
with increasing global service and support revenues associated with a growing
customer base.

  Cost of Revenue

   Cost of Product Revenue.  Cost of product revenue was $3.5 million,
resulting in a product gross margin of 96.7%, in 2000 compared to $2.4 million,
resulting in a product gross margin of 96.6%, in 1999.

   Cost of Service Revenue.  Cost of service revenue was $26.5 million,
resulting in a service gross margin of 44.3%, in 2000 compared to $21.1
million, resulting in a service gross margin of 38.2%, in 1999. The increase in
service gross margin was primarily attributable to efficiencies realized from
deploying our service personnel over a growing customer base.

                                     -28-



  Operating Expenses

   Research and Development.  Research and development expenses were $26.9
million, or 17.6% of total revenue, in 2000 compared to $21.2 million, or 20.1%
of total revenue, in 1999. This increase in research and development expenses
in dollar amount was primarily the result of an increase in personnel, an
increase in the use of external contractors and depreciation expenses arising
from the acquisition of computer equipment.

   Sales and Marketing.  Sales and marketing expenses were $63.7 million, or
41.6% of total revenue, in 2000 compared to $43.8 million, or 41.5% of total
revenue, in 1999. This increase in sales and marketing expenses was due to
continuing investments in our direct enterprise sales capability and associated
marketing activities.

   General and Administrative.  General and administrative expenses were $12.0
million, or 7.9% of total revenue, in 2000 compared to $10.5 million, or 9.9%
of total revenue, in 1999. General and administrative expenses decreased as a
percentage of revenue due to economies of scale achieved as a result of
infrastructure investments.

   Amortization of Goodwill and Purchased Intangible Assets.  Amortization of
goodwill and purchased intangible assets was $7.8 million in 2000 compared to
$454,000 in 1999.

   Write-off of Assets and Related Costs.  In August 1999, our subsidiary, IONA
Technologies, Inc., relocated its U.S. headquarters from Cambridge,
Massachusetts to a larger facility in Waltham, Massachusetts. As a result of
this relocation, we wrote off assets and incurred costs totaling $1.7 million.
There was no write-off of assets in 2000.

   Settlement of Litigation.  In March 2000, RSA and the Massachusetts
Institute of Technology filed suit against us alleging that we breached the
terms of our patent license agreement with RSA. In June 2000, we entered into a
confidential settlement agreement with RSA to settle all outstanding claims
among the parties. Costs associated with the settlement of this litigation
amounted to $1.4 million.

  Income from Operations

   We generated an operating profit of $11.3 million, or 7.4% of total revenue,
in 2000 compared to an operating profit of $4.4 million, or 4.1% of total
revenue, in 1999. Operating profit, as adjusted to eliminate stock
compensation, amortization of goodwill and purchased intangible assets,
write-off of assets and related costs, and settlement of litigation would have
been $20.9 million, or 13.7% of total revenue, in 2000 and $6.5 million, or
6.2% of total revenue, in 1999. The increased operating margin in 2000
(eliminating stock compensation, amortization of goodwill and purchased
intangible assets, write-off of assets and related costs, and settlement of
litigation) reflects our continued efforts to develop and market our product
family, and to develop an enterprise sales capability.

  Other Income, Net

   Interest income, net, represents interest earned on cash and investment
balances. Interest income, net was $4.1 million in 2000 compared to $2.6
million in 1999, primarily due to greater amounts available for investment and
higher interest rates.

   Net exchange loss was $384,000 in 2000 compared to a net exchange loss of
$379,000 in 1999. The increase in net exchange loss for 2000 was primarily due
to the strength of the dollar against the euro.

  Gain on Sale of Investment and Other Income

   Gain on sale of investment and other income for 2000 is comprised primarily
of the realized gains earned on the sale of over 75% of our investment in a
publicly-owned company. There were no shares sold in 1999.

                                     -29-



  Income Taxes

   Income taxes were $2.8 million in 2000 compared to $1.1 million in 1999,
representing an effective tax rate of approximately 16.5% for 2000 and 16.6%
for 1999. Deferred tax assets were not recognized in respect of the net
operating loss carryforwards in either year because realization was not
sufficiently assured.

   If tax authorities in jurisdictions other than Ireland were to challenge
successfully the manner in which profits are recognized within IONA or, more
generally, the jurisdiction in which income is subject to taxation, our
prevailing effective tax rate will increase and our cash flows and results of
operations could be materially adversely affected.

   At December 31, 2000, we had a net operating loss carryforward of
approximately $24.5 million for U.S. federal income tax purposes. At December
31, 2000, we had a net operating loss carryforward of approximately $1.9
million for Australian tax purposes, which carries forward indefinitely. At
December 31, 1999, we had a net operating loss carryforward of approximately
$3.0 million for U.S. federal income tax purposes, which expires from 2011 to
2014.

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 exchange losses of $468,000 for 2001 and $384,000 for 2000. We
cannot accurately predict the impact of future exchange rate fluctuations on
our results of operations. Prior to 1999, we had sought to hedge the risks
associated with fluctuations in exchange rates of the Irish pound and the euro
to the dollar. In the future, we may undertake transactions to hedge the risks
associated with fluctuations in exchange rates of the euro and other currencies
to the dollar. Any hedging techniques implemented by us may not be successful
and exchange rate fluctuations may materially adversely affect our business,
financial condition and results of operations. See also Item 11. "Quantitative
and Qualitative Disclosure About Market Risk."

B.  Liquidity and Capital Resources

   We announced on February 28, 2002 a public offering of 4,000,000 of our
American Depositary Shares, representing 4,000,000 of our ordinary shares, at a
price of $15.00 per share. The underwriters exercised in full their option to
purchase an additional 600,000 shares to cover over-allotments. The net
proceeds from the offering of the 4,600,000 shares were approximately $63.7
million.

   Net cash provided by operating activities was $38.1 million in 2001, $24.0
million in 2000 and $1.1 million in 1999 which includes the net sale of
marketable securities of $34.7 million in 2001 and investments in high quality,
marketable securities (net of sales and maturities) of $4.3 million in 2000 and
$3.4 million in 1999. Net cash provided from financing activities was $7.6
million in 2001, $22.6 million in 2000 and $12.2 million in 1999 which includes
the issuance of shares (net of issuance costs) of $7.6 million in 2001, $22.6
million in 2000 and $11.4 million in 1999.

   During 2001, we:

  .   invested $5.4 million for the purchase of furniture, fixtures and
      equipment, for further investment in our management information systems
      and for capital expenditures relating to increased employee headcount;

  .   acquired Netfish Technologies, Inc. and as part of the acquisition
      expended $30.9 million;

  .   acquired Object-Oriented Concepts, Inc. and as part of the acquisition
      expended $3.0 million; and

  .   invested $15.5 million in technology which had reached technological
      feasibility.

                                     -30-



   We are obligated to make average lease payments of approximately $1.2
million per year through 2023 (subject to an option to exit in 2013) with
respect to our Dublin, Ireland facility; approximately $2.0 million per year
through 2006 with respect to our U.S. subsidiary's Waltham, Massachusetts
facility; approximately $530,000 per year through 2006 with respect to our U.S.
subsidiary's San Mateo, California facility; approximately $1.9 million per
year through 2006 with a majority ending in 2005 with respect to our U.S.
subsidiary's Santa Clara, California facility; approximately $276,000 per year
through 2004 with respect to our U.S. subsidiary's Reston, Virginia facility;
approximately $196,000 per year through 2014 (subject to an option to exit in
2009) with respect to our Reading, U.K. facility; and approximately $122,000
per year through 2009 (subject to an option to exit in 2004) with respect to
our Frankfurt, Germany facility.

   We believe that our current sources of liquidity are sufficient to finance
our operations 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
"Business Overview-- Patents and Proprietary Technology."

   The total amount spent in the last three years on IONA-sponsored research
and development activities is $88,361,000, excluding intangible assets and
in-process research and development. Of that amount, $40,260,000 was spent in
2001, $26,906,000 was spent in 2000 and $21,195,000 was spent in 1999.

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."

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

  Executive Share Option Scheme

   In May 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, 2001, an aggregate of 173,371 of our ordinary shares
remain issuable upon the exercise of options outstanding and options available
for grant under the Executive Share Option Scheme.

  1997 Share Option Scheme

   Our Board of Directors and shareholders approved the 1997 Share Option
Scheme in January 1997 and February 1997, respectively, and amendments in July
1998, March 2000 and May 2001 to increase the number of ordinary shares
reserved for grant under the 1997 Share Option Scheme. The 1997 Share Option
Scheme, as amended, provides for the grant of share options to our employees,
consultants, directors and officers. The 1997 Share Option Scheme provides for
the issuance of up to 12,900,000 of our ordinary shares. Generally, under the
1997 Share Option Scheme, an award is not transferable by the award 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 incentive stock options issued
to employees holding more than 10% of our total combined voting power.

                                     -38-



   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 employees 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, 2001, an aggregate of 11,143,461 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 January 1997 and February 1997, respectively. The 1997
Director Share Option Scheme provides for the grant of options to purchase a
maximum of 250,000 of our ordinary shares to our non-employee directors.

   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 and 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 and (2) an option to purchase
an additional 3,000 ordinary shares at the time of each other annual meeting of
shareholders after the first anniversary of such director's initial award,
provided, however, that such person has continuously served as a non-employee
director during such period. 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, assuming such director satisfies specified requirements.
The term of each option will be for a period of ten years from the date of
grant. As of December 31, 2001, an aggregate of 196,000 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 Plan

   In connection with our June 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, 2001, an aggregate of 34,501
of our ordinary shares remained reserved for grant upon exercise of these
converted Genesis stock options. We do not intend to grant any more options
under the Genesis 1997 Stock Plan.

  Object-Oriented Concepts, Inc. Stock Option Plan

   In connection with our February 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, 2001, an aggregate of 29,942
of our ordinary shares remained reserved for grant upon exercise of these
converted OOC stock options. We do not intend to grant any more options under
the OOC Stock Option Plan.


                                     -39-



  Netfish Technologies, Inc. 1999 Stock Option Plan

   In connection with our May 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, 2001, an aggregate of 323,406 of our
ordinary shares remained reserved for grant upon exercise of these converted
Netfish stock options. An aggregate of 249,673 shares were available for future
grant or issuance under Netfish 1999 Stock Option Plan as of December 31, 2001.

  1999 Employee Share Purchase Plan

   In August 1999, we established a qualified Employee Share Purchase Plan
under which up to 500,000 ordinary shares may be issued. 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 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. Unless terminated sooner, the 1999 Employee Share Purchase
terminates on June 9, 2009. As of December 31, 2001, 166,197 shares have been
issued under the 1999 Employee Share Purchase Plan.

Item 7.  MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

A.  Major Shareholders

   The following table sets forth, as of June 1, 2002, the number of ordinary
shares owned by all shareholders who we know to own beneficially more than five
percent (5%) of our ordinary shares.

   In addition, Guaranty Nominees Limited is the nominee holder of JPMorgan
Chase Bank (as successor to Morgan Guaranty Trust Company of New York), as
depositary under the Deposit Agreement dated as of February 24, 1997 among us,
the depositary and the holders from time to time of ADRs issued thereunder, and
as such is the holder of record as depositary of 25,914,451 ADSs representing
the 25,914,451 ordinary shares deposited under the deposit agreement. Guaranty
Nominees Limited is not the beneficial owner of the shares as determined in
accordance with the rules of the Securities and Exchange Commission.

   Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission and is based on 32,586,860 ordinary shares
outstanding as of June 1, 2002, which includes an aggregate of up to 299,011
ordinary shares issuable as of June 1, 2002 to the former Netfish shareholders
prior to reduction for indemnification payments to which we may be entitled.
For the purposes of calculating the number of ordinary shares and the
percentage beneficially owned by a person or entity, ordinary shares issuable
by us to that person or entity pursuant to options which may be exercised
within 60 days of June 1, 2002 are deemed to be beneficially owned and
outstanding. Except as otherwise indicated, each shareholder named in the
following table has sole voting and investment power with respect to the shares
set forth opposite that shareholder's name.

price of $15.00 per share. The underwriters exercised in full their option to
purchase an additional 600,000 shares to cover over-allotments. The 4,600,000
shares were offered by an underwriting group led by Lehman Brothers Inc., SG
Cowen Securities Corporation and Prudential Securities Incorporated. We will
use the net cash proceeds of the offering for general corporate purposes,

                                     -41-



including working capital. We may also use a portion of the net proceeds to
acquire additional businesses, technologies and products.

Exchange, including the requirement that certain transactions receive the
approval of shareholders. For further information, shareholders should consult
their own financial advisors. The following table sets forth the high and low

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 ADR, 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 transfer to or by the
order of or on behalf of residents of the Federal Republic of Yugoslavia,
Serbia, Iraq, Angola or in respect of funds and financial resources belonging
to the Taliban of Afghanistan, unless permission for the transfer has been
given by the Central Bank of Ireland.

   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 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. 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 and does not discuss all aspects of
Irish taxation that may be relevant to any particular Irish 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 and U.S. Holders that legally and
beneficially hold their ordinary shares or ADSs evidenced by ADRs as capital
assets and does not address 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

                                     -45-



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 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 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 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%.

   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 Irish CGT purposes and applied against capital gains
in future years.

  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. Gifts or inheritances between spouses are not subject to
Irish CAT.

  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. 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 (Euro)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

                                     -46-



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 (Euro)12.50.

   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 that (i) is resident in the United
States for the purposes of the Treaty, (ii) is not also resident in, or
ordinarily resident in, Ireland for Irish tax purposes, (iii) is not engaged in
any trade or business and does not perform independent personal services
through a permanent establishment or fixed base in Ireland, and (v) where a
holder is a corporation, is not ultimately controlled by persons resident 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 should the Depositary for the ADSs (JP Morgan Chase Bank, as successor
to Morgan Guaranty Trust Company of New York, the depositary under the Deposit
Agreement dated as of February 24, 1997 among IONA, Morgan Guaranty Trust
Company and the holders from time to time of ADSs issued thereunder) enter into
an intermediary agreement with the Irish Revenue Commissioners prior to the
payment of dividends by us. 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.

                                     -47-



   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.

  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 (the 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 Irish
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
Irish CAT.

   In a case where an inheritance of ordinary shares or ADSs is subject to both
Irish 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 Irish 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 Irish CAT and U.S. federal gift tax since 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. 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;

                                     -48-



  .   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, 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

                                     -49-



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.

   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
"Foreign Investment Company" and "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 ordinary income 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. 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 will not generally 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 will generally 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 "Foreign Investment Company" and
"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 time of sale or other
disposition. In the case of individuals, long-term capital gains are generally
taxed at a maximum rate of 20%, or 18% for assets acquired after the year 2000
and held for more than five years. 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.

  Personal Holding Company

   A foreign corporation may be classified as a personal holding company for
U.S. federal income tax purposes if both of the following two tests are
satisfied:

  .   at any time during the last half of the company's taxable year, five or
      fewer individuals (without regard to their citizenship or residency)
      actually or constructively own, under attribution rules, more than 50% of
      the stock of the corporation by value; and

                                     -50-



  .   60% or more of the foreign corporation's gross income derived from U.S.
      sources or effectively connected with a U.S. trade or business, as
      specifically adjusted, is from passive sources such as dividends,
      interest, rent and royalty payments.

   In general, a personal holding company is currently taxed at a rate of 38.6%
on its undistributed personal holding company income, which is generally
calculated based on the corporation's taxable income, after making certain
adjustments. We cannot provide any assurance that either test will not be
satisfied in 2002 or in future years because it is difficult to make accurate
predictions of future income and the amount of our shares an individual will
actually or constructively own in us.

  Foreign Personal Holding Company

   A foreign corporation may be classified as a foreign personal holding
company for U.S. federal income tax purposes if both of the following two tests
are satisfied:

  .   five or fewer individuals (who are U.S. citizens or residents) actually
      or constructively own, under attribution rules, more than 50% of all
      classes of the corporation's stock measured by voting power or value at
      any time during the corporation's taxable year; and

  .   the corporation receives at least 60% (50% if previously a foreign
      personal holding company) of its gross income regardless of source, as
      specifically adjusted, from passive sources such as dividends, interest,
      gains from the sale or exchange of securities, rent and royalty payments.

   If a corporation is classified as a foreign personal holding company, a
portion of its undistributed foreign personal holding company income, as
defined for U.S. federal income tax purposes, is imputed to all of its
shareholders who are U.S. Holders on the last taxable day of the corporation's
taxable year, or, if earlier, the last day on which it is treated as a foreign
personal holding company. The imputed income is taxable as a dividend, even if
no cash dividend is actually paid. U.S. Holders who dispose of their ordinary
shares or ADSs before that date would not be subject to U.S. federal income tax
under these rules. We cannot provide any assurance that we will not be
classified as a foreign personal holding company in 2002 or in future years
because it is difficult to make accurate predictions of future income and the
amount of our shares a U.S. citizen or resident will actually or constructively
own in us.

  Foreign Investment Company

   A foreign corporation may be classified as a foreign investment company for
U.S. federal income tax purposes if, at any time during a taxable year when 50%
or more by vote or value of the corporation's outstanding stock is owned,
directly or indirectly, by U.S. Holders, it is:

  .   registered as a management company or unit investment trust under the
      Investment Company Act of 1940, as amended; or

  .   engaged, or holding itself out as being engaged, primarily in the
      business of investing, reinvesting, or trading in securities,
      commodities, or any interest, including a futures or forward contract or
      option, in securities or commodities.

   In general, if a corporation is classified as a foreign investment company
at any time during the period a U.S. Holder holds the corporation's stock, any
gain from the sale or exchange of stock in that corporation by the U.S. Holder
will be taxable as ordinary income to the extent of the U.S. Holder's ratable
share of the corporation's accumulated earnings and profits. We cannot provide
assurance that we will not be classified a foreign investment company in 2002
or future years because it is difficult to make accurate predictions of the
amount of our capital stock U.S. Holders will directly or indirectly own in us.

                                     -51-



  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

  .   50% or more of the assets of the corporation in a taxable year, averaged
      over the year and ordinarily determined based on fair market value,
      consist of assets that either produce or are held for the production of,
      passive income.

   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 must
      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 are taxed at the
      highest rate in effect for that year on ordinary income and the tax is
      subject to an interest charge at the rate applicable to deficiencies for
      income tax.

  .   The entire amount of gain that is recognized by a U.S. Holder upon the
      sale or other disposition of our ordinary shares or ADSs evidenced by
      ADRs will also be considered an excess distribution and will 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 will 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 will
      instead be equal to the decedent's adjusted tax basis, if lower. A U.S.
      Holder cannot 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 will not apply to the U.S. Holder. Instead, that
U.S. Holder will 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, including a passive foreign investment company annual
information statement, 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.

   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 will generally 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
      will recognize the amount of the excess as ordinary income;

                                     -52-



  .   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 may recognize the amount of the difference as ordinary loss.
      Losses will 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 will 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. Also, a significant decline in the market
price of our ordinary shares or ADSs may result in our being 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 30% 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 Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended,
made pursuant to the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995, These forward-looking statements are neither
promises nor guarantees and involve risks and uncertainties, 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.

   We enter into foreign exchange contracts as a hedge against accounts payable
in currencies other than the U.S. dollar and as a hedge against firm
commitments in foreign currencies. Market value gains and losses are recognized
on hedges of payables, and the resulting credit or debit offsets 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 are
deferred until the hedged transaction is completed and are then included in the
measurement of the value of the hedged transaction. At December 31, 2001, 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.

   We entered into certain equity investments for the promotion of business and
strategic objectives, and typically do not attempt to reduce or eliminate the
inherent market risks on these investments. These strategic investments, in a
private company, are classified as available-for-sale at the balance sheet
date, with unrealized gains or losses recorded in shareholders' equity. At
December 31, 2001, the fair value of these investments was approximately
$50,000.

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

                        REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of
IONA Technologies PLC

   We have audited the accompanying consolidated balance sheets of IONA
Technologies PLC as of December 31, 2001 and 2000 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, 2001. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of IONA Technologies PLC at December 31, 2001 and 2000, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended December 31, 2001, in conformity with accounting principles
generally accepted in the United States.

                             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"), provides enterprise
infrastructure 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 generally accepted accounting principles in the United States.
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 and China after eliminating all material intercompany accounts
and transactions.

  Companies Acts, 1963 to 2001

   The financial information relating to IONA and its subsidiaries included in
this document does not comprise full accounts as referred to in Section 19 of
the Companies (Amendment) Act, 1986, 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 financial statements for the years ended December 31, 2000 and 1999.
Copies of full accounts for each of the years ended December 31, 2000 and 1999
have been so annexed to the relevant annual returns, and a copy of the full
accounts for the year ended December 31, 2001 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 2002.

  Foreign Currency Translation

   The U.S. dollar is the functional currency for the Company. 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 period.

  Revenue Recognition

   The Company's revenue is derived from product license fees and charges for
services. For the three year period ended December 31, 2001, the Company
followed the revenue recognition criteria of Statement of Position 97-2,
Software Revenue Recognition ("SOP 97-2"), as amended by SOP 98-4 and SOP 98-9
issued by the Accounting Standards Executive Committee of the American

arrangement to deliver software does not require significant 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;

      .   vendor's fee is fixed or determinable; and

      .   collectibility is probable.

   Where the Company enters into a multiple element arrangement consisting of
both products and services, revenue is allocated between the elements based on
vendor-specific objective evidence of fair values. The portion of the fee
allocated to an element is recognized when the four criteria for revenue
recognition stated above have been met.

   Professional services are provided primarily on a time and materials basis
for which revenue is recognized in the period that the services are provided.
Where the professional services relate to arrangements requiring significant
production, modification or customization of software, and the service element
does not meet the criteria for separate accounting, the entire arrangement,
including the software element, is accounted for in conformity with the
percentage-of-completion contract accounting method. Percentage-of-completion
is generally measured using output measures, primarily arrangement milestones
where such milestones indicate progress to completion.

  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 and Cash Equivalents

   IONA 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. 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 earnings.

  Investments

   Investments consist of equity securities and are stated at market value. All
investments are defined as available-for-sale securities under the provisions
of Statement of Financial Accounting Standards No. 115 "Accounting for Certain
Investments in Debt and Equity Securities" ("SFAS 115"), and any unrealized
holding gains and losses are reported as a separate component of shareholders'
equity, as accumulated other comprehensive income (loss).

  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 IONA's product
development process, technological feasibility is established upon completion
of a working model. Development costs incurred by IONA between completion of
the working model and the point at which the product is ready for general
release have been insignificant.

   The Company expensed the full amount of the cost of acquired in-process
research and development during the year ended December 31, 2001 as the
technology had not reached technological feasibility and had no alternative
uses.

  Other Non-Current Assets

   Other non-current assets represent costs of technology purchased or acquired
on acquisitions which have reached technological feasibility and the fair value
at date of acquisition of assembled workforces related to the Company's
acquisitions as described in Note 4. The costs of technology have been
capitalized and will be written off over their useful economic life of four
years in accordance with SFAS 86. The cost associated with the acquisition of
assembled workforces will be written off over four years. Amortization expense
was $12,689,000, $2,198,000 and $390,000 in 2001, 2000 and 1999, respectively.

   Reviews are regularly performed to determine whether facts or circumstances
exist which indicate that the carrying value of other non-current assets is
impaired. No indicators of impairment have been identified to date and there
has been no need to carry out an impairment calculation.

  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
4, and is being amortized on a straight line-basis over four years.
Amortization expense was $59,784,000, $4,806,000 and $64,000 in 2001, 2000 and
1999, respectively.

   Reviews are regularly performed to determine whether facts or circumstances
exist which indicate that the carrying value of goodwill is impaired. No
indicators of impairment have been identified to date and there has been no
need to carry out an impairment calculation.

   In June 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 141, "Business Combinations" ("SFAS 141"),
and No. 142, "Goodwill and Other Intangible Assets" ("SFAS 142"), effective for
fiscal years beginning after December 15, 2001 as further described below in
Accounting Pronouncements.

  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:


                                                          
      Motor vehicles........................................ 5 years

  Concentration of Credit Risk

   IONA sells its products to companies in various industries throughout the
world. IONA maintains reserves for potential credit losses. To date such losses
have been within management's expectations. IONA had an allowance for doubtful
accounts of approximately $1,321,000 and $926,000 at December 31, 2001 and
2000, respectively. IONA generally requires no collateral from its customers.

   IONA 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, 2001, $24,110,000 was invested in marketable
securities held for trading purposes, comprised of $10,981,000 in commercial
paper and $13,129,000 in U.S. government agency securities, under the
management of two financial institutions. IONA 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.

  Employment Grants

   Employment grants are credited to the income statement and offset against
the related payroll expense in two equal installments, the first on the
creation of the job and the second on the first anniversary thereof.

  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

   IONA uses the liability method in accounting for income taxes. 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.

  Accumulated Other Comprehensive Income

   Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
("SFAS 130") establishes guidelines for the reporting and display of
comprehensive income and its components in financial statements. Comprehensive
income includes unrealized gain or loss on equity securities classified as
available-for-sale in accordance with SFAS 115, and is included as a component
of shareholders' equity.

  Stock Compensation

   IONA 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 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).

   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 compensation and credited to additional paid-in
capital in the period of transfer.

   On May 8, 2001, a wholly-owned subsidiary of IONA merged with and into
Netfish Technologies, Inc. ("Netfish"), for total consideration of 5,036,318
newly-issued IONA Ordinary Shares and replacement options, and $30.9 million 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) has, in accordance with the requirements of FASB
Interpretation No. 44 "Accounting for Certain Transactions Involving Stock
Compensation", been accounted for as deferred stock compensation and is being
charged to expense as stock compensation ratably over the remaining vesting
period of each tranche of unvested options.

   On July 1, 1999, IONA acquired the outstanding shares of Aurora
Technologies, Inc. ("Aurora") for consideration of $520,000 payable in cash and
the issuance of 48,750 shares to certain individuals in two equal installments
on the first and second anniversary of the acquisition, provided they remain
employees of IONA at the anniversary dates. The value of these shares,
$780,000, was accounted for as deferred stock compensation and was credited to
additional paid-in capital and charged to expense as stock compensation on a
straight-line basis over the 2 year period in which the stock was issued. At
December 31, 2001, deferred stock compensation for Aurora was fully amortized.

   During 2001, IONA accelerated the vesting of stock options granted to
certain employees whose employment was terminated. IONA recognized compensation
expense of $233,000 in accordance with the requirements of FASB Interpretation
No. 44 "Accounting for Certain Transactions Involving Stock Compensation."

   Stock compensation expense of $2,013,000, $404,000, and $372,000, for the
periods ended December 31, 2001, 2000 and 1999, respectively can be attributed
to personnel in the following departments: global services $406,000, nil and
nil; research and development $849,000, nil and nil; sales and marketing
$283,000, nil and nil; restructuring $233,000, nil and nil and general and
administrative $242,000, $404,000, and $372,000, respectively.

  Defined Contribution Plan

   IONA sponsors and contributes to a defined contribution plan for certain
employees and directors. Contribution amounts by IONA are determined by
management and allocated to employees on a pro rata basis
based on employees' contributions. IONA contributed approximately $1,916,000,
$1,411,000 and $1,201,000 to the plan in the years ended December 31, 2001,
2000 and 1999, respectively.

  Advertising and Promotion Expense

   All costs associated with advertising and promoting products are expensed as
incurred. Advertising and promotion expense was $10,077,000, $3,801,000 and
$3,076,000 for the years ended December 31, 2001, 2000 and 1999, respectively.

  Accounting Pronouncements

   The Financial Accounting Standards Board issued Statement No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133") in
June 1998. SFAS 133, which requires all derivative instruments to be recognized
as either assets or liabilities on the balance sheet at their fair value,
provides a comprehensive and consistent standard for the recognition and
measurement of derivatives and hedging activities. As amended, this statement
is effective for fiscal years beginning after June 15, 2000 and therefore

                                     F-10



                             IONA TECHNOLOGIES PLC

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

applied to IONA from the first quarter of 2001. Application of the new rules
had no material impact on the consolidated financial statements of the Company
as it had no derivative or hedging transactions in 2001.

   The Financial Accounting Standards Board issued Statement No. 141, "Business
Combinations," ("SFAS 141"), and No. 142, "Goodwill and Other Intangible
Assets," ("SFAS 142") in June 2001. Under the new rules, goodwill and
intangible assets deemed to have indefinite lives will no longer be amortized
but will be subject to annual impairment tests in accordance with these
Statements. Other intangible assets will continue to be amortized over their
useful economic lives. The Statements are effective for fiscal years beginning
after December 15, 2001.

   IONA will apply the new rules on accounting for goodwill and other
intangible assets beginning in the first quarter of 2002. Application of the
non-amortization provisions of SFAS 142 is expected to result in a reduction in
expenses for 2002 of $86.2 million, or $3.37 per share. During 2002, IONA will
perform the first of the required impairment tests of goodwill and
indefinite-lived intangible assets as of January 1, 2002. Based on current
circumstances, the Company believes the application of the new rules will not
have a material impact on the consolidated financial statements of the Company.

   The Financial Accounting Standards Board issued Statement No. 143,
"Accounting for Asset Retirement Obligations" ("SFAS 143") in June 2001. SFAS
143 requires entities to record the fair value of a liability for an asset
retirement obligation in the period in which it is incurred. When the liability
is initially recorded, the entity capitalizes a cost by increasing the carrying
amount of the related long-lived asset. Over time, the liability is accreted to
its present value each period, and the capitalized cost is depreciated over the
useful life of the related asset. Upon settlement of the liability, an entity
either settles the obligation for its recorded amount or incurs a gain or loss
upon settlement. SFAS 143 is effective for fiscal years beginning after June
15, 2002, with earlier application encouraged. Based on current circumstances,
the Company believes the application of the new rules will not have a material
impact on the consolidated financial statements of the Company.

   The Financial Accounting Standards Board issued Statement No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144"),
in August 2001. SFAS 144 addresses financial accounting and reporting for the
impairment or disposal of long-lived assets and supersedes SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to be Disposed Of," and the accounting and reporting provisions of APB Opinion
No. 30, "Reporting the Results of Operations" for a disposal of a segment of a
business. SFAS 144 is effective for fiscal years beginning after December 15,
2001, with earlier application encouraged. The Company will adopt SFAS 144 as
of January 1, 2002 and it does not expect that the adoption of the Statement
will have a significant impact on the Company's financial position and results
of operations.

2.  Marketable Securities

   Marketable securities are considered to be trading securities per SFAS 115
and are carried on the balance sheet at their market value.

3.  Investments

   Investments consist of equity securities and are stated at market value. All
investments are defined as available-for-sale securities under the provisions
of Statement of Financial Accounting Standards No. 115, "Accounting for Certain
Investments in Debt and Equity Securities" ("SFAS 115"), and any unrealized
holding gains or losses are reported as a separate component of shareholders'
equity, as accumulated other comprehensive income (loss). During 2000, the
Company sold over 75% of the investment made in 1999 and realized gains of
$1,880,000 on these sales. The Company sold the remaining investment in 2001
and realized gains of $164,000. There were no sales of available-for-sale
securities in 1999.

4.  Acquisitions

  Netfish Technologies, Inc.

   On May 8, 2001, a wholly-owned subsidiary of IONA merged with and into
Netfish, for a total consideration of 5,036,318 newly-issued IONA Ordinary
Shares and replacement options, and $30.9 million of closing costs incurred in
connection with the merger. Of the 4,221,216 newly-issued Ordinary Shares,
504,598 will be held back by IONA as a source of indemnification payments that
may become due to IONA. These Ordinary Shares will be issued and distributed to
the former holders of the outstanding Netfish shares over a two-year period
from the date of merger, after adjusting for any indemnification payments made.
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
acquisition based primarily on an independent valuation.

   The acquisition was accounted for using the purchase method of accounting,
and accordingly, the assets, liabilities, and operating results have been
included in the accompanying consolidated financial statements from the date of
acquisition.

   The total purchase price for Netfish consists of 4,221,216 newly-issued IONA
Ordinary Shares at a fair market value of $55.00 per share, the fair value of
815,102 replacement options of IONA shares, and $30.9 million in cash to pay
Netfish's related disposal expenses. The aggregate purchase price plus related
direct acquisition costs and net liabilities assumed, less the amount allocated
to unearned compensation expense, totaling $294.0 million has been allocated to
the acquired assets and liabilities as follows:

                                                     ========


   IONA expensed $3.6 million in respect of acquired in-process research and
development, based upon an independent valuation of the current fair value of
specifically identified Netfish research and development projects for which
technological feasibility had not been established and for which alternative
future uses did not exist. In estimating such current fair value, the estimated
future after-tax cash flows attributable to the identified projects were
considered, and were then discounted to present value utilizing discount rates
commensurate with the risks of reaching technological feasibility, completing
the in-process projects, and achieving estimated cash flows (the discount rate
averaged 25%).

   Both other non-current assets and goodwill recorded in connection with the
Netfish acquisition are being amortized on a straight-line basis over their
useful economic lives of four years. The fair value of Netfish's tangible
assets at acquisition date was approximately $4.8 million and its liabilities
assumed totaled approximately $15.4 million.

  Object-Oriented Concepts, Inc.

   On February 8, 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 IONA Ordinary Shares and
replacement options. Of the 730,453 newly issued Ordinary Shares, 262,129 were
subject to return to IONA as a purchase price adjustment upon the failure to
achieve certain performance targets. 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 acquisition based primarily on an
independent valuation.

   The acquisition was accounted for using the purchase method of accounting,
and accordingly, the assets, liabilities, and operating results have been
included in the accompanying consolidated financial statements from the date of
acquisition.

   The total purchase price for OOC consisted of 730,453 newly-issued IONA
Ordinary Shares at a fair market value of $59.68, the fair value of 178,131
replacement options and $3.0 million in cash. The aggregate purchase price plus
related direct acquisition costs of $40.3 million, net of tangible assets
acquired of $0.7 million, has been allocated to the acquired assets and
liabilities as follows:

   Both other non-current assets and goodwill recorded in connection with the
OOC acquisition are being amortized on a straight-line basis over their useful
economic lives of four years. The fair value of OOC's tangible assets at
acquisition date was approximately $1.4 million and its liabilities assumed
totaled approximately $0.7 million.

   Certain of the performance targets applicable to the 262,129 newly issued
Ordinary Shares subject to return were achieved in August 2001. Accordingly,
IONA allocated $2.8 million of additional purchase price to goodwill,
representing the fair market value of 174,735 Ordinary Shares no longer subject
to return, at the time these performance targets were achieved.

  Software A.G., Inc.

   On February 7, 2001, IONA acquired the non-exclusive license rights to
certain portions of Software AG, Inc.'s enterprise application integration
technology for $10 million. The software has reached technological feasibility,
and accordingly the cost has been capitalized and will be written off over its
useful economic life of four years, in accordance with SFAS 86. In addition to
the acquisition of the non-exclusive license rights to the technology, IONA has
hired a substantial portion of the Software AG, Inc. engineering team
responsible for the development of the technology.

  Genesis Development Corporation

   On June 13, 2000, a wholly-owned subsidiary of IONA merged with and into
Genesis Development Corporation, a Pennsylvania corporation ("Genesis"),
pursuant to which Genesis became a wholly-owned subsidiary of IONA, resulting
in the issuance of 331,744 newly-issued IONA Ordinary Shares and 126,423
Ordinary Shares issuable upon assumed Genesis stock options. Of the 331,744
newly-issued Ordinary Shares,

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

176,156 Ordinary Shares were subject to return to IONA as a purchase price
adjustment upon the failure to achieve certain performance targets. The
contingency was resolved in May 2001. Accordingly, IONA allocated $6.5 million
of additional purchase price to goodwill, representing the fair market value of
these 176,156 Ordinary Shares no longer subject to return, at the time the
contingency was resolved. Goodwill is being amortized on a straight-line basis
over its useful economic life of four years.

   The acquisition was accounted for under the purchase method of accounting,
and accordingly, the assets, liabilities, and operating results have been
included in the accompanying consolidated financial statements from the date of
acquisition.

   The initial total purchase costs of $16.2 million, comprising the fair value
of the shares issued not subject to relinquishment, the intrinsic value of the
options issued and related costs, was allocated, based on their respective fair
values, to other non-current assets (assembled workforce) of $1.2 million,
goodwill of $14.0 million and net assets acquired of $1.0 million. Both other
non-current assets and goodwill are being amortized on a straight-line basis
over their useful economic lives of four years. The fair value of Genesis'
assets at acquisition date was approximately $2.0 million and its liabilities
assumed totaled approximately $1.0 million.

  Watershed Technologies, Inc.

   On February 23, 2000, IONA purchased substantially all the assets of
Watershed Technologies, Inc., a provider of XML--based tools and services for
building standards-based business-to-business and business-to-consumer portals,
for $13.3 million. The costs have all been allocated to goodwill as the fair
value of net assets acquired was approximately nil.

  Aurora Technologies, Inc.

   On July 1, 1999, IONA acquired the outstanding shares of Aurora
Technologies, Inc. for a consideration of $520,000 payable in cash and the
issuance of 48,750 shares to certain individuals in two equal installments on
the first and second anniversary of the acquisition, provided they remain
employees of IONA at the anniversary dates. The value of these shares,
$780,000, was accounted for as deferred stock compensation and was credited to
additional paid in capital and charged to expense as stock compensation on a
straight-line basis over the two
year period in which the stock was issued. Stock compensation expense amounted
to $194,000, $390,000 and $196,000 in 2001, 2000 and 1999, respectively. The
acquisition was accounted for using the purchase method of accounting. Cash
consideration of $510,000 has been allocated to goodwill (Note 1) as the fair
value of the net assets acquired was approximately nil.

  Pro Forma Disclosures

   The following unaudited pro forma summary presents the consolidated results
of operations of the Company as if the foregoing acquisitions had occurred on
January 1, 2000 and January 1, 2001 and does not purport to be indicative of
what would have occurred had the acquisition been made as of the beginning of
2000 and 2001 or of results which may occur in the future. The pro forma
results give effect to certain purchase accounting adjustments, including
additional amortization expense from goodwill and other non-current assets,
additional compensation expense on unearned stock compensation arising on the
exchange of unvested options held by Netfish employees in exchange for unvested
options granted by IONA, and the issuance of additional Ordinary Shares in
connection with the acquisitions.

5.  Restructuring

   In 2001, IONA's management and board of directors approved restructuring
plans, which included initiatives to integrate the operations of the recently
acquired companies, consolidate duplicative facilities and reduce overhead.
Total accrued restructuring costs of $5.7 million were recorded related to
these initiatives.

   Accrued restructuring charges included approximately $3.7 million
representing the cost of involuntary employee separation benefits related to
approximately 195 employees worldwide. Employee separation benefits include
severance, medical and other benefits. Employee separations affect the majority
of business functions, job classes and geographies, with a majority of the
reductions in the United States and Europe. The restructuring plans also
included costs totaling approximately $2.0 million associated with the closure
and consolidation of office space, principally in the United States.

   In 2001, IONA substantially completed the approved restructuring plans,
resulting in payments of $3.7 million in severance and related benefits to
employees worldwide and $0.7 million in facility closure costs. Amounts
remaining at December 31, 2001 of $1.3 million relate to additional facility
closure and consolidation costs with cash outlays expected to be completed by
the end of 2004.

6.  Restricted Cash

   IONA has approximately $1,078,000 in restricted cash deposits securing
annual renewable letter of credit facilities with Fleet National Bank, relating
to the Waltham, Massachusetts and Santa Clara, California leased facilities.
Should IONA not renew these letter of credit facilities or default on its
rental obligations, this amount will be payable to the lessor.

12.  Redeemable Preference Shares, Warrants and Shareholders' Equity

   IONA's authorized share capital is divided into Redeemable Preference Shares
("Preference Shares") of (Euro)0.0025 par value per share and Ordinary Shares
of (Euro)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

                                     F-18



                             IONA TECHNOLOGIES PLC

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

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 accounting principles generally
accepted 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, 2001, 2000 and 1999, at the exchange rates in effect
on those dates, were approximately nil, $28,000,000 and $22,000,000,
respectively.

   In December 1999, in connection with a major license agreement, the Company
issued 42,900 share purchase warrants to the licensee. The warrants were
exercisable immediately at a price of $34.125 per share and expire on December
20, 2003. At December 31, 2001 no share purchase warrants were outstanding.

   The Company determined the fair value of the warrant at the time of issuance
using a Black-Scholes option pricing model with the following weighted-average
assumptions: risk free interest rate of 6.5%; dividend yields of 0%; volatility
factors of the expected market price of the Company's Ordinary Shares of 0.913
and a weighted-average expected life of the option of four years. The
determined value of the warrants was debited to revenue and credited to
additional paid-in capital in 1999.

13.  Share Option Scheme

   IONA 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, IONA has
recognized compensation expense of $1,780,000, $404,000 and $372,000, during
2001, 2000 and 1999, 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 Aurora and Netfish acquisitions (Note 4).

   During 2001, IONA accelerated the vesting of stock options granted to
certain employees whose employment was terminated. IONA recognized compensation
expense of $233,000 in 2001 in accordance with the requirements of FASB
Interpretation No. 44 "Accounting for Certain Transactions Involving Stock
Compensation."

   IONA's Executive Share Option Scheme has authorized the grant of options to
personnel for up to 1,125,500 shares of IONA's A Ordinary Shares. 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.

   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 IONA. 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

                                     F-19



                             IONA TECHNOLOGIES PLC

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

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
incentive stock options issued to employees holding more than 10% of the total
combined voting power of IONA.

   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.

   Pro forma information regarding net income and earnings per share is
required by Statement 123, and has been determined as if IONA had accounted for
its stock options under the fair value method of that Statement. 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 for 2001,
2000 and 1999, respectively: risk-free interest rates of 5%, 5% and 6%;
dividend yields of 0%; volatility factors of the expected market price of
IONA's Ordinary Shares of 1.10, 1.13 and 1.27; and a weighted-average expected
life of the option of five years.

   For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. IONA's pro
forma information follows for the years ended December 31, 2001, 2000 and 1999

   At December 31, 2001, the Company has a net operating loss carryforward of
approximately $42.0 million for U.S. federal income tax purposes which will
expire in the tax years 2008 through 2021 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.
subsidiary.

   At December 31, 2001, approximately $24.5 million 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 it is not expected that it will reverse. At December 31,
2001, $9.8 million of the valuation allowance related to disqualifying
dispositions.

   At December 31, 2001, IONA also had net operating loss carryforwards
totaling approximately $2.0 million 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 IONA 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.

19.  Subsequent Events (Unaudited)

   On February 28, 2002 the Company announced the public offering of 4,000,000
of its American Depositary Shares, representing 4,000,000 of its ordinary
shares at a price of $15.00 per share. The underwriters exercised in full their
option to purchase an additional 600,000 shares to cover over allotments. The
net proceeds from the offering of 4,600,000 shares were approximately $63.7
million, which will be used for general corporate purposes, including working
capital and the possible acquisition of additional businesses, technologies and
products.

   On February 28, 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, IONA allocated $1.2
million 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.
