Proven IONA Application Server Platform Generates Significant Savings with
Re-use of Legacy IT systems

Waltham, MA & Zurich, Switzerland - January 27th, 2003 - IONA®, the leading
provider of Rapid Integration software (NASDAQ: IONA), today announced that
Credit Suisse entered into an enterprise development and runtime license
agreement in the fourth Quarter of 2002 for use of IONA's Orbix E2A(tm)
Application Server Platform (ASP).

Credit Suisse first began using IONA's CORBA* technology in 1998 to enable
the interoperability of mainframe-based applications with Web-based
technologies. This latest agreement for the use of IONA's Orbix E2A
Application Server Platform will enable Credit Suisse to further extend and
optimise legacy applications in support of reduced management costs,
accelerated system enhancements and real-time data access for both internal
staff and customers.

Orbix E2A ASP's service-oriented deployment infrastructure facilitates the
design and integration of applications via a standards-based interface or as
a "service," making them transparently interoperable across disparate IT
environments, including mainframe systems. With Orbix E2A ASP, Credit Suisse
successfully consolidated and integrated several back-end mainframe OS/390
systems with a variety of front-end applications to support the company's
larger e-business efforts. The platform enables the creation and deployment
of business processes or new, large-scale enterprise applications quickly,
with minimal code development, while preserving original
qualities-of-service (QoS), such as security.

This flexibility and manageability has translated into greater business
efficiency for Credit Suisse. "IONA's Orbix E2A is helping us experience the
benefits of a standards-based, service-oriented integration infrastructure,"
said Andreas Manz, Head of IT Systems Engineering, Member of the Management
Committee Technology and Operations of Credit Suisse. "By adopting open
standards technology we are protecting our legacy IT assets while also
ensuring the scalability of the platform over time in meeting ongoing
technology and systems integration requirements. With improved levels of
performance across our business systems we are continuing to realise
significant returns in cost savings and service levels."

"We are extremely proud of what IONA has been able to achieve to date for
Credit Suisse and are confident that we can continue to deliver significant
cost benefits within the framework of this latest license agreement," said
Barry Morris, CEO at IONA.

Orbix E2A(tm) Application Server Platform
IONA's Orbix E2A Application Server Platform (ASP) is the industry's only
enterprise deployment infrastructure for distributed Web services, Java 2,
Enterprise Edition(tm) (J2EE(tm)) and CORBA applications. Orbix E2A ASP 6.0
enables organizations to proactively leverage their existing operating
platforms, programming language expertise, and legacy application
investments when building new, large-scale integrated business applications
that support reduced costs, increased efficiency, and greater business
flexibility. In support of enterprise-scale distributed applications
involving multiple technologies, it also provides a set of application
services that offer a single point of integration for security, messaging,
transactions, load balancing and fault tolerance, and management.

IONA's Orbix E2A product lines benefit from the company's commitment to open
standards. IONA is an active member of the Web Services Interoperability
(WS-I) Organisation and the SOAPBuilders Forum-independent organizations
dedicated to the promotion and interoperability of Web services standards.
IONA recently hosted the SOAPBuilders Interoperability Lab Round III at its
Waltham, MA headquarters. At the event, IONA's Orbix E2A XMLBus demonstrated
superior support and interoperability across WSDL and with all SOAP encoding
styles. IONA is also an active member of other industry standards bodies
including the W3C, OASIS, and OMG.
