Ease of Implementation of Interwoven Enterprise Content Management Version 5.5 Cited as Key Reason for On-time Launch of Site

Sunnyvale, Calif. - September 16, 2002 - Interwoven, Inc. (Nasdaq: IWOV), the leader in Enterprise Content Management (ECM), today announced Company 39, a subsidiary of Parsons Brinckerhoff Inc., launched the www.lowermanhattan.info site in 50 days using Interwoven as its Enterprise Content Management platform. Earlier this year, Company 39 was hired by the New York City Economic Development Corporation to develop a site dedicated to Lower Manhattan and the rebuilding of the World Trade Center sites. Interwoven's proven ease of implementation, ease of administration and ease of use were key factors in achieving this on-time, on-budget launch.

"We could not have built this site in such a short time without Interwoven, period," said Doug Eberhard, CTO and senior vice president for Company 39. "Imagine trying to architect an interactive, 600-page site, integrating content from 60 different government agencies, and getting it up-and-running in less than 60 days."

The centralized site contains a wealth of content that will, moving forward, be updated by the 60 government agencies themselves. From transit schedules to transportation maps, rebuilding plans to recreation, cleanup efforts to community involvement, there is now one source that provides people who live in, work in, and visit Lower Manhattan with regularly updated news and information about the area. The goal of having the site available prior to the September 11th anniversary put both the Company 39 team and the Interwoven software to the test.

"My team has been very impressed with the improvements in the Interwoven platform in terms of ease-of-implementation, ease-of-administration and ease-of-use," continued Eberhard. "Using Interwoven, we have built a platform that will make it easy for the non-technical employees at the New York agencies to keep the site fresh and up to date."

Many TeamSite 5.5 features sped up implementation for Company 39, including the out-of-the-box workflows and the easy-to-use graphical workflow builder. Company 39 also made extensive use of TeamSite Templating software to significantly reduce the time needed to create new pages. Moving forward, templating will also empower the direct contribution of content by the agencies themselves. Using TeamSite 5.5 software, Company 39 also built a customized administration portal that ties site maintenance, management, review and reporting into a single branded interface.

"New York City Mayor Michael Bloomberg and New York State Governor George Pataki both underscored how impressed they were with the Website, and how quickly we were able to pull together information from so many different sources," said Janette Sadik-Khan, president of Company 39. "The skills, hard work, and dedication of our staff, as well as the rapid deployment capabilities of Interwoven, gave us the edge we needed in order to deliver such a critical project in such a short time."

Special site features include an interactive transportation map covering all modes of transportation, a virtual tour of 50 Lower Manhattan sites, a user-friendly tool for navigating assistance and incentives programs, and an interactive timeline charting the rich history of Lower Manhattan.
