TIBCO AND GEMSTONE ANNOUNCE ENTERPRISE SERVICES SOLUTION FOR GOVERNMENT SECTOR

Co-Development Initiative Delivers Fully Integrated Platform For Real-Time Information View
Across the Enterprise

Palo Alto, CA and Beaverton, OR - May 14, 2003 — TIBCO Software Inc. (Nasdaq:TIBX), a leading enabler of Real-Time Business and the leading independent business integration software company in the world, as demonstrated by market share and analyst reports, and GemStone Systems, a 20- year leader in data distribution, caching and management software, today announced availability of Enterprise Services Solution (ESS), an enterprise integration platform which enables government agencies to gain a real-time view of information within their agencies or between agencies. Armed with this information, agency management can quickly and easily share information and make better-informed decisions. RABA Technologies, a leading systems integrator for the government sector, will implement ESS for initial customers.

“The ESS, which includes TIBCO’s real-time technology and GemStone’s GemFire data solution, will give intelligence, security, civilian law enforcement and other government agencies the ability to efficiently gather, process and analyze massive amounts of data for rapid, well-informed response against threats, to formulate best practices and preventative measures, and to facilitate inter-agency cooperation,” said Jeff Summers, vice president, industry solutions, TIBCO Software Inc.

Managing High Volumes of Data- Intensive Solutions In A Low Cost Infrastructure
Government agencies face increasing pressure to consolidate disparate IT architectures and applications for faster decision-making, while holding down costs. Costs associated with consolidation, however, can be a prohibitive barrier to growth and information flow. ESS meets these challenges by eliminating bottlenecks and latencies inherent in existing and legacy platforms, and offers ease of implementation, rapid ROI and low total cost of ownership.

“We have commenced integration of the ESS for initial customers, and anticipate demand for the solution will continue to reflect the increasing demand government agencies are experiencing to leverage a wide variety of information for increased collaboration, efficiency and security,” said Robert Baruch, CEO, RABA Technologies.

ESS Presented at Homeland Security Summit, May 15 – 16, 2003

ESS will be presented at a series of events and seminars over the next 12 months. The first event is a breakfast for government executives on May 14, 2003 at the Ritz Carlton Diplomat Room, Pentagon City. The event will feature a presentation given by Karl Gumtow, Senior Vice President, RABA Technologies. GemStone and TIBCO will also be showing this new architecture on May 15-16, 2003 at booth 72, Homeland Security Summit, Hyatt Regency, Arlington, Virginia.
