ORLANDO, Fla., TUCON(TM) 2006, April 12, 2006 -- TIBCO Software Inc. (Nasdaq: TIBX), today announced at TUCON 2006, the company's annual user conference, the general availability of TIBCO BusinessWorks(TM) 5.3, the latest release of the company's flagship integration solution designed to help customers easily unlock the true benefits offered by an enterprise-scale service-oriented architecture (SOA). With this new version, TIBCO offers additional support for emerging Web Services standards, greater flexibility to quickly create services with one-click user interface features, and integrated partner management support to help ensure service reuse across multiple trading partners.

Under the TIBCO BusinessWorks umbrella, TIBCO also announced today an upgrade to its BusinessConnect(TM) software offering -- now re-named TIBCO BusinessWorks(TM) Partner Connect -- to support business-to-business (B2B) partner integration within an SOA framework. By tightly coupling B2B with SOA, customers can build a more agile, responsive and cost-effective value chain through the sharing of information and business logic, as well as provide real-time visibility into information and processes. Consequently, strategic composite applications can leverage not only internal systems, but partner systems as well. These new features enable the rapid rollout of services and more streamlined automation of routine processes, helping companies to build stronger and more collaborative relationships with customers and suppliers.

"TIBCO's SOA strategy offers everything needed to create, expose and govern reusable services across the enterprise, both inside and outside the firewall," said Ram Menon, senior vice president, Marketing and Strategy, TIBCO. "SOA technologies and standards focus on the world within the organization, while the trading partner ecosystem outside an organization is often ignored. TIBCO's integrated partner management solution enables the secure exchange of documents and automation of transactions across public and private networks for exceptional trading community management. With these new releases, TIBCO solidifies its position of offering the most comprehensive and flexible foundation for an enterprise SOA available on the market today."

New and Enhanced Support for SOA & Reuse

TIBCO BusinessWorks 5.3 includes the following new features for SOA integration:

-- New Wizards for Easier Web services Creation -- One-click turns TIBCO BusinessWorks processes into Web services without having to define WSDL or other parameters WSDLs can be generated without coding using templates

-- Services Represented More Intuitively in Context of SOA -- Users can choose user interface perspectives

-- UDDI Export Capabilities at Design and Deployment Time -- The ability to publish WS details to UDDI registry, while abstracting complexity of non-relevant detail

-- Services Reuse -- Now easier to extend or reuse composite services and processes across enterprise TIBCO BusinessWorks 5.3 and TIBCO BusinessWorks Partner Connect now support today's latest Web Services standards, including:

-- WS-Security (XML Digital Signature and XML Encryption) -- Allows users to encrypt particular elements of a message without the need to encrypt the entire message. Also features payload encryption, which enables encrypted messages to bridge disparate transport protocols and guarantees encryption and authentication between end points. In addition, the policy-based security functionality means rules can be added or changed without having to modify existing services.

-- WS-I (Basic Profile) Certification -- Ensures interoperability across different vendors' Web Services stacks and guarantees interoperability between partners in B2B scenarios.

-- SOAP 1.2 -- Supported over both HTTP and JMS transports
