Exhibit 99.1 BROADVISION IN AGREEMENT TO ACQUIRE INTERLEAF, THE E-CONTENT COMPANY Highly Innovative XML-based e-Content Tools, Combined with Strength in e-Business Applications, Will Enable BroadVision to Make XML Revolution Mainstream WALTHAM, MA - JANUARY 26, 2000 - Interleaf, Inc. (Nasdaq: LEAF), the leading provider of XML-based e-content(TM) solutions, today announced that it has entered into a definitive agreement providing for the acquisition of Interleaf by BroadVision, the leader in personalized e-business applications. Key to the acquisition is the e-Content Company, a division of Interleaf and leader in XML-based content management tools. This separate Interleaf business unit is dedicated to the development, marketing and sale of XML-based content management tools which enable the design, creation and management of dynamic and intelligent content for web and wireless applications. The e-Content Company comprises nearly 70 percent of Interleaf's approximately 400 employees and has been the most significant area of growth and investment within Interleaf over the past two years. Under the terms of the agreement each outstanding share of Interleaf common stock will be exchanged for .3465 shares of BroadVision common stock, and all outstanding options and warrants to purchase Interleaf common stock will be assumed by BroadVision. Based on basic shares outstanding as of January 25, 2000 and both companies' closing price as of that date, the transaction represents approximately a 40% premium over Interleaf's current value. On a fully diluted basis, BroadVision would issue approximately 5.6 million shares of its common stock, having a value of approximately $877 million based on BroadVision's closing stock price on January 25, 2000. The transaction is intended to be tax-free to the Interleaf shareholders and will be accounted for as a purchase transaction. The transaction, which has been unanimously approved by both the Interleaf and BroadVision Boards of Directors, is subject to certain customary closing conditions, including approval by Interleaf's stockholders, Hart-Scott-Rodino antitrust clearance and other regulatory approvals. The companies expect to close the transaction by May 31, 2000. "Through the acquisition of Interleaf, a leader in the development of XML-based e-content management tools, BroadVision will be able to quickly expand our leadership in delivering personalized e-business solutions for web and wireless applications," said Dr. Pehong Chen, President, CEO and Chairman of the Board for BroadVision. "With our combined customer base of more than 2,500 blue-chip companies, both firms have the proven ability to meet e-business demands for a fast time to market, easier integration with content sources and back-end systems, and high performance and scalability. We look forward to leveraging the strengths of both companies to provide increased benefits for customers and shareholders." "At Interleaf, we have spent the past three years repositioning the company around new XML technology and the delivery of content to wireless devices," said Jaime Ellertson, President, CEO and Chairman of the Board for Interleaf. "This past year we have successfully penetrated the e-business marketplace by delivering state-of-the-art XML-based e-content management tools. We believe strongly that these tools and our initiative into the wireless market make us a unique fit with BroadVision's strength in web applications and with their strategic objectives. Both companies see XML-based content proving itself to be of particular importance for the fast growing business-to-business e-commerce market. Therefore, the combination of our e-content management tools integrated with BroadVision's e-business applications make a powerful end-to-end solution for the B2B market while further extending these applications to the emerging wireless market." BENEFITS OF ACQUISITION FOR CUSTOMERS The combination of the suite of BroadVision One-To-One(TM) personalized e-business applications and Interleaf's XML-based e-content management tools will create one of the most comprehensive, end-to-end offerings for companies needing rich content and transactional data to drive e-business over the Web and to wireless devices. GartnerGroup estimates that by 2003, 80 percent of application-to-application traffic passing over public networks will be in XML ("Reality Check: XML Today" by Dr. Rita Knox, GartnerGroup, October 1999). Specific benefits of the combined products will include: o LESS TIME AND LOWER COST FOR E-CONTENT MANAGEMENT. The integrated offering combines Interleaf's XML-based e-content management tools and BroadVision's real-time instant publishing tools to shorten time to production for content. This lowers the total cost of ownership for companies by enabling publishers to more easily create, publish, manage and re-purpose transactional content. Additionally, the integrated offering is differentiated by its support for the publication of XML-based documents from Microsoft(R) Office applications, greatly expanding general business users' ability to publish Web and wireless content. o AUTOMATE B2B E-COMMERCE THROUGH INTELLIGENT CONTENT. The integrated offering will enable the automation of B2B e-commerce by enabling companies to improve their operations via the use of intelligent content. Intelligent content is personalized, reusable and dynamically assembled in real time to increase collaboration and communication among commerce partners. Unlike static content, intelligent content automates interactions and transactions among participants, creating a highly productive information value chain. o EXPANDED E-BUSINESS REACH. The integration of Interleaf's X-WAP (wireless application protocol) technology will enable BroadVision customers to deploy e-business applications that enable access to dynamic content from mobile and other wireless devices, such as digital cellular telephones, pagers, personal digital assistants and e-books. End-users will be able to access in real time personalized product information, inventory, price, and catalog data and to execute orders from Web sites and wireless devices via BroadVision's ability to deliver "e-business anywhere, anytime." The Yankee Group has estimated that wireless subscribers accessing the Internet will grow from 669 million in 1999 to 1.26 billion by 2005 (The Yankee Group, November, 1999). Therefore, BroadVision believes the integration of Interleaf's X-WAP technology will be a significant benefit for companies implementing e-business applications capable of providing dynamic, personalized content to the growing number of users of wireless devices. THE BROADVISION AND INTERLEAF FIT The two companies share a vision for enabling e-business through a common commitment to an XML backbone. Interleaf, a thought and industry leader for XML-based e-content management tools, brings people, tools and technologies that are complementary to BroadVision's offerings. For example, Interleaf's employees represent one of the world's largest XML talent pools. And, Interleaf's technology leadership in XML and X-WAP are technologies that supplement those of BroadVision. Additionally, Interleaf has a large worldwide base of more than 2,000 customers who are potential users of BroadVision's e-business applications. KEY TECHNOLOGIES BroadVision intends to fully integrate Interleaf's next generation content management tools based on XML into BroadVision's full suite of e-business applications.

Interleaf's XML wireless application technology, currently under development, will transform XML into HTML, WML, PDF, ASCII and raw text business content for delivery to wireless devices, such as digital cellular telephones, pagers, personal digital assistants and e-books. o QUICKSILVER(TM). A full-featured high-end authoring and publishing product with an extension to enable the generation of XML-based content.
