SUNNYVALE, Calif.and REDWOOD CITY, Calif. -September 12, 2000. Interwoven, Inc. (Nasdaq: IWOV) and AlterEgo Networks, Inc. today announced a strategic alliance to deliver an integrated solution that will allow their joint customers to create, adapt and publish enterprise Web content to wireless devices such as Web-enabled phones, personal digital assistants (PDAs), or pagers. In conjunction with the partnership, Interwoven also has announced that it will make a minority investment in AlterEgo.

Under the terms of the agreement, Interwoven and AlterEgo will integrate elements of AlterEgo's adaptation technology with Interwoven's enterprise-class content management system in order to optimize delivery of "intelligent" wireless Web content. The integrated solution is expected to ship in Q1 2001. Together, Interwoven and AlterEgo are working to ensure that companies can effectively extend their Web content to customers, partners and employees, who choose to access information via Web-enabled phones or PDAs.

"Enterprise-class content management will be a requirement in any meaningful wireless initiative, and Interwoven has identified the unique challenges that the wireless channel presents to enterprise development efforts," said Richard Ling, CEO of AlterEgo Networks"Customers will benefit from Interwoven's industry-leading TeamSite solution and experience in servicing marquee enterprise clients. Together we will bring timely, relevant content to an increasingly mobile eBusiness environment."

"Our enterprise clients recognize that in order to maximize their outreach to customers and partners, they must leverage their corporate networks and customer-facing Web content to reach wireless devices," said Martin Brauns, president and CEO of Interwoven. "AlterEgo's Adaptive Network, combined with Interwoven's intelligent content management solutions, will allow enterprises to publish content to any device type, using any wireless standard, significantly extending their eBusiness channels."

Investment in AlterEgo Builds on Interwoven Wireless Initiative

The Gartner Group predicts there will be four times as many mobile phones and handheld computers as desktop systems by 2005, indicating that for many people, wireless devices will become the preferred channel for accessing corporate eBusiness sites. Interwoven's strategic partnership and equity investment in AlterEgo builds on its commitment to delivering world-class solutions for enabling wireless access to eBusiness content. In July 2000, Interwoven acquired wireless software start-up Neonyoyo and established a new Wireless Division to enhance and accelerate its wireless content management offering.

"Interwoven's leading eBusiness customers are turning to us to extend their Web production to include the wireless Web. We believe that AlterEgo will play a major role in addressing the network requirements associated with bringing content to a mobile workforce," said John Van Siclen, vice president of corporate development for Interwoven.
