Jacada Integrator Enhances Application Integration Solution by

Maximizing the Value of Legacy Systems

Jacada Ltd. (NASDAQ: JCDA), a leading provider of legacy integration, extension and emulation solutions for eBusiness, today announced its support for Universal Application Network--the industry's first standards-based, vendor-independent application integration solution--launched by Siebel Systems in conjunction with industry-leading application software vendors, integration server vendors, and systems integrators. Siebel Systems, Inc. (NASDAQ: SEBL) is a leading provider of multichannel eBusiness applications software.

As part of this endorsement, Jacada plans to provide out-of-the-box connectivity between Jacada Integrator and Universal Application Network. The combined solution will give enterprise organizations a cost-effective way to integrate their legacy systems, thereby allowing them to deliver high-payback, low-risk solutions and enhanced productivity. Jacada and SeeBeyond jointly demonstrated this live integrated solution running on the SeeBeyond Business Integration Suite in the Partner Pavilion at Siebel Worldwide User Week 2002. Jacada plans to submit the solution to the Siebel Validation Program within 90 days of Siebel Worldwide User Week 2002.

Universal Application Network takes a standards-based, vendor-independent approach to the design and development of end-to-end best-practice business processes that are executed by market-leading integration servers. Based on XML and Web Services industry standards, Universal Application Network enables organizations to effectively integrate best-in-class applications, such as Jacada Integrator, and ensures that organizations are not locked into vendor-specific proprietary architectures.

Leveraging Universal Application Network as a common integration platform, Jacada and Siebel Systems will deliver an enhanced solution that combines best practices drawn from both Siebel Systems' business process library and Jacada's approach to integrating legacy mainframe and midrange computing systems. Jacada's support for Universal Application Network brings together two industry-leading technologies to provide an off-the-shelf solution which enables rapid access between eBusiness applications and core legacy applications that handle the majority of organizations' transactional processing. This solution will allow companies to take advantage of their legacy infrastructure, using robust, real-time business processes that can span the enterprise.

Jacada Integrator is complementary to the enterprise integration server vendors and systems integrators supporting Universal Application Network. When complex business processes require access to legacy systems such as mainframe, midrange, and DEC VAX, Jacada Integrator provides point-to-point access to single or multiple legacy applications. Jacada Integrator bridges the gap between old and new computing systems across business processes by seamlessly unlocking the core enterprise data and business logic buried in legacy applications.

"Organizations are looking to leverage existing investments in legacy systems in order to achieve faster ROI, reduced deployment time, and lower total cost of ownership," said Mike Chandler, Director of Product Management for Jacada, Ltd. "Our support for Universal Application Network enables organizations to extend their ability to integrate business processes with existing legacy systems, thus better serving their customers."

"Jacada Integrator is a leading solution for integrating Siebel eBusiness Applications with host-based legacy applications. Legacy applications are a significant component of our customers' application portfolios," said Michael Straub, Alliance Technical Director for Siebel Systems. "Jacada's support for Universal Application Network allows our customers to gain competitive advantage by rapidly and cost-effectively harnessing the investments they have made in legacy applications."

Jacada is a Siebel Strategic Software Partner and is a leading provider of seamless, nonintrusive, real-time integration solutions between Siebel eBusiness Applications and legacy systems. Jacada has over 40 joint customers with Siebel Systems. Jacada Integrator version 3.5 has been validated with Siebel 7.
