TIBCO Software and MITEM Corporation Expand Strategic Alliance

New joint marketing agreement strengthens existing relationship and extends the reach of TIBCO's mainframe integration solutions

MENLO PARK, CA - April 24, 2002 - MITEM Corporation and TIBCO Software Inc. (Nasdaq: TIBX) today announced a new joint marketing agreement that further aligns product development, sales and marketing activities to provide superior end-to-end mainframe and midrange integration solutions. This new agreement extends a global technology alliance that was announced in February 2000.

MITEM is a TIBCO preferred partner for legacy integration software and TIBCO is a MITEM preferred partner for enterprise application integration software. MITEM's signature product, MitemView®, provides non-invasive integration to legacy mainframe and midrange systems. MitemView enables real-time integration of and between disparate systems without requiring changes or additions to existing applications. TIBCO ActiveEnterprise™ is a comprehensive line of Enterprise Application Integration (EAI) products that automate business processes and lower total cost of ownership by creating an integrated network of applications, databases and information. MitemView is used to provide the last mile connection between TIBCO ActiveEnterprise and myriad legacy systems.

"MITEM has proven to be a trustworthy and effective partner in the engagements we have completed around the world," said Murat Sonmez, senior vice president of marketing, TIBCO Software. "The MITEM-TIBCO combination will enable customers to accelerate the deployment of their end-to-end integration projects by connecting a broad range of mainframe and midrange systems. Using the joint solution, customers can leverage existing infrastructure investments and show business value in days rather than months."

MITEM's Screen-based Host Adapter for TIBCO ActiveEnterprise completes TIBCO's line-up of mainframe integration products that include support for transaction processing systems, direct database access and file transfers. In addition to extending TIBCO's integration capability with IBM mainframe systems, MitemView connects TIBCO ActiveEnterprise to non-IBM platforms including Unisys, Tandem, Bull, ICL, Digital VAX and Data General Systems.

"Our joint value proposition has been proven at blue-chip accounts like GE ERC and Harley-Davidson," said Gale Aguilar, president of MITEM. "These early successes have given us great confidence in the long-term importance of our alliance with TIBCO Software. Our customers have enjoyed accelerated delivery of projects and a rapid return on investment by combining quick business wins with the systematic deployment of their EAI infrastructure."

MITEM has been selected as a Gold Sponsor of the Strategic Directions 2002 conference to be held in San Francisco in May. Every year, at this invitation-only event, Reuters and TIBCO bring together great minds in business and technology to learn and share vision and insights on today's most pressing business problems and innovative technology solutions. MITEM will use this opportunity to preview the new MitemView adapter for TIBCO ActiveEnterprise 4.0. Visitors to MITEM's booth will see a demonstration of MitemView and ActiveEnterprise in action. MITEM's experts will be on-hand to discuss legacy integration requirements with TIBCO and Reuters customers.
