##### Table of Contents



This annual report, and other reports, proxy statements and
other communications to shareholders, as well as oral statements
made by our officers or agents, contain forward-looking
statements within the meaning of the safe harbor
provisions of the Private Securities Litigation Reform Act of
1995 that relate to future events or our future financial
performance. In some cases, you can identify forward-looking
statements by terminology, such as may,
will, should, could,
expect, plan, anticipate,
believe, estimate, project,
predict, intend, potential,
or continue or the negative of such terms or other
comparable terminology, although not all forward-looking
statements contain such terms. In addition, these
forward-looking statements include, but are not limited to,
statements regarding, among other things, our future revenue,
operating income (loss), net income (loss) per ordinary share
and per ADS, products and services, sources of liquidity,
markets, anticipated tax rates, and plans and objectives of
management. Such statements are neither promises nor guarantees
but rather are subject to a number of risks and uncertainties
which could cause actual results to differ materially from those
described in the forward-looking statements. Factors that may
cause such variation are discussed in Item 5
Operating and Financial Review and Prospects,
Item 3.D. Risk Factors and our reports filed
with the Securities and Exchange Commission.

Our future revenue depends upon the evolution and adoption of
Web services and related integration and infrastructure
solutions in support of new computing models including service
oriented architecture, or SOA.






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




We derive a significant amount of revenue from customers in a
limited number of industries and our business and results of
operations could be adversely effected by significant changes in
those industries.




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

| |  | Maintain Technological Leadership in Standards-based
    Computing. We have a history of technological leadership and
    dedication to continuous product improvement. Our CORBA-based
    Orbix product family is the leading enterprise CORBA solution.
    Our Web services-based Artix product family and our open source
    initiative continue the Orbix tradition by addressing the
    integration needs, from mainframe environments to mobile
    computing platforms, of large IT organizations through high
    performance, standards-based solutions. We will continue to
    invest heavily in research and development. By promoting and
    embracing existing and emerging industry standards in our
    commercial products and our open source initiative, we intend to
    facilitate the broad acceptance of our offerings. We may acquire
    businesses, products or technologies that we believe will
    enhance and expand our current product offerings.

| |  | Expand Our Customer Base, While Retaining Our Existing
    Customers. Many of our customers are Global
    2000 companies in a variety of industries, including
    telecommunications, financial services, government and
    manufacturing/distribution, that are deeply invested in both our
    products and our architectural approach to integration. The
    strategic importance of our products allows us, working with our
    partners, to develop strong relationships with our
    customers key technology decision makers. In addition, our
    strategic selling approach facilitates broad adoption of our
    products throughout a customers IT organization. All of
    these factors combine to represent an opportunity for us to
    continue to present new generations of technology solutions to
    our enterprise customers in the telecommunications, government
    and financial services industries. At the same time, the broader
    popularity of Web services gives us an opportunity to go beyond
    our traditional customer base to attract new customers that have
    deployed complex, costly and heterogeneous computing

| |   | environments. We believe these new customers are interested in
    the reductions in IT cost and complexity that Web services and
    SOA can deliver. We also believe these new customers will find
    our traditional, distributed architectural approach, combined
    with our new generation of Web services integration solutions,
    compelling and competitive.

| |  | Leverage and Expand Strategic Alliances. We understand
    that relationships with leading software and other technology
    vendors, as well as system integrators, create opportunities to
    gain customers in broader markets than those otherwise available
    to us. We are focused on leveraging our established
    relationships and forging new alliances to enhance our
    marketing, selling and implementation initiatives. We believe
    that many of these vendors and system integrators seek to
    partner with strong infrastructure technology providers that
    will enable them to more rapidly satisfy customer needs. We have
    existing relationships with leading software and technology
    vendors, such as AmberPoint, BEA, Business Objects, IBM,
    Microsoft, Oracle, Sun Microsystems, and global system
    integrators, such as BearingPoint, Computer Sciences Corporation
    (CSC), LogicaCMG, NEC, NS Solutions, Satyam and Wipro. 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.

|Item 5. | Operating and Financial
    Review and Prospects

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

| |  | Excess distributions by us to a U.S. Holder would be taxed
    in a special way. Excess distributions are amounts
    received by a U.S. Holder with respect to our ordinary
    shares or ADSs in any taxable year that exceed 125% of the
    average distributions received by such U.S. Holder from us
    in the shorter of either the three previous years or the
    U.S. Holders holding period for the ordinary shares
    or ADSs before the current taxable year. Excess distributions
    must be allocated ratably to each day that a U.S. Holder
    has held our ordinary shares or ADSs. A U.S. Holder would
    be required to include amounts allocated to the current taxable
    year and years before we became a passive foreign investment
    company as ordinary income. In addition, amounts allocated to
    each taxable year beginning with the year we first became a
    passive foreign investment company would be taxed at the highest
    rate in effect for that year on ordinary income and the tax
    would be subject to an interest charge at the rate applicable to
    deficiencies for income tax.
|
| |  | The entire amount of gain that is realized by a U.S. Holder
    upon the sale or other disposition of our ordinary shares or
    ADSs evidenced by ADRs would also be considered an excess
    distribution and would be subject to tax as described above.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
|
| |  | The adjusted tax basis in our ordinary shares or ADSs evidenced
    by ADRs acquired from a decedent who was a U.S. Holder of
    the ordinary shares or ADSs would not be increased to equal the
    fair market value of such ordinary shares or ADSs as of the date
    of the decedents death but would instead be equal to the

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

    might recognize the amount of the difference as ordinary loss.
    Losses would be allowed only for the amount of net mark to
    market gain previously included by the U.S. Holder under
    the election for prior taxable years; and

    or ADSs to market for all taxable years during which the
    U.S. Holder owned our ordinary shares or ADSs and we were a
    passive foreign investment company, the excess
    distribution rules generally would not apply to the
    U.S. Holder.
