TIBCO's Real-Time Infrastructure Software Included In Interwoven's Content Interchange Framework; Interwoven TeamSite To Be Integrated With TIBCO ActivePortal

SUNNYVALE, CA and PALO ALTO, CA, August 29, 2000 - Interwoven, Inc. (Nasdaq: IWOV) and TIBCO Software Inc. (Nasdaq: TIBX), today announced a strategic alliance to provide comprehensive solutions for business-to-business marketplaces and portals.

The recently announced Interwoven Content Interchange Framework will include the TIBCO ActiveEnterprise e-business product suite as a key enterprise integration component, enabling Interwoven customers to manage content from their enterprise applications in real-time. TIBCO ActiveEnterprise suite will enable joint customers to become real-time e-businesses by seamlessly integrating back-end systems such as ERP, product databases and customer databases, with their Web initiatives. The Interwoven Content Interchange Framework builds on Interwoven's success in delivering a scalable, inclusive content management architecture, while focusing on the new unique challenges facing trading partners across an exchange, including enterprise integration.

"Real time enterprise data and fresh, relevant content are critical for today's market exchanges and portals," said Vivek Ranadiv, chairman and CEO of TIBCO Software Inc. "Interwoven's content management solutions will provide our customers with improved quality control over the enterprise and external data that TIBCO technology seamlessly integrated into their exchanges and portals."

Interwoven and TIBCO also announced today that Interwoven's XML-based TeamSite Templating software will be integrated with the TIBCO ActivePortal product suite, delivering integrated content management and presentation for TIBCO's portal customers. TeamSite Templating allows easy content entry and tagging including tagging for use across multiple TIBCO ActivePortal-based sites. The TIBCO ActivePortal suite also works seamlessly with TIBCO ActiveEnterprise, enabling enterprises to leverage their integrated application network and B2B commerce infrastructure to provide an integrated, unique set of real-time content and interactive services to their portal audience. TIBCO is the only end-to-end e-business infrastructure company that provides integration, B2B connectivity and portal infrastructure in a single, integrated product line.

"Our blue-chip customers will greatly benefit from the strength of the Interwoven-TIBCO relationship," said Martin Brauns, president and CEO of Interwoven. "With the integration of TIBCO ActivePortal and Interwoven TeamSite, we will provide a powerful, open, best of breed solution for the rapidly growing enterprise portal market."

The core of TIBCO's real-time software infrastructure offering is the TIBCO ActiveEnterprise suite, designed for building a complete, end-to-end Internet and enterprise infrastructure that successfully scales to the most demanding business information networks. It provides a real-time e-business integration platform that encompasses data integration and transformation, business process coordination, messaging, enterprise portals and alerting, adapters for legacy, packaged and third-party applications, plus enterprise monitoring and management.

The TIBCO ActivePortal product suite extends TIBCO's comprehensive ActiveEnterprise infrastructure to include preparation and presentation of personalized content to individual users. TIBCO ActivePortal performs three primary roles in the creation of a portal: comprehensive integration of enterprise applications, services, and content; portal user management, including authentication, user access control, and portal category, profile, and page personalization; and page assembly and presentation using templated output and integrated services.

The recently announced Interwoven Content Interchange Framework consists of three core elements: eBusiness network collaboration, enterprise integration, and access to exchange-based services. The framework consists of Interwoven solutions - including currently available products and new technologies under development - in combination with solutions provided directly from select partners such as TIBCO. The Interwoven Content Interchange framework is an extension of Interwoven's enterprise-class content management platform to address the specific needs in infrastructure, features and processes that customers require in order to focus on delivering the speed, quality and interactivity their B2B initiatives require.
