Diversified Energy Company's Employees Collaborate on More Than 100,000 Pages of Enterprise Content on its Corporate Intranet and Internet, Accelerating Multiple Initiatives Nation-wide

SUNNYVALE, Calif. - August 19, 2002 - Interwoven, Inc. (Nasdaq: IWOV), the leader in Enterprise Content Management (ECM), today announced that NiSource Inc. (NYSE: NI), one of the largest natural gas distribution and transmission operations in the U.S., has gone live with Interwoven's enterprise content management solution to capture, manage, and scale all enterprise content on its company intranet and Internet sites. Interwoven ECM will help NiSource manage the growing number of assets as the 100,000+ pages on these internally and externally facing sites will soon be easily scaled to meet their demanding content needs.

"As one of the largest gas distribution businesses in the United States, it was imperative that NiSource have all our sites meet the needs of our 3.7 million customers," said Joyce Shroka, team leader, information technology at NiSource Inc. "Interwoven's enterprise content management solution allows us to easily scale to the number of contributors, number of assets and frequency of site updates."

Prior to Interwoven, NiSource had no enterprise wide content management solution and therefore had to rely solely on the expertise of their Internet/intranet teams across the enterprise. NiSource's knowledge workers stored and maintained all documents on their local servers and then sent site change requests to the IT team who would create new pages or move pages to production as needed. With Interwoven ECM, instead of opening a change request for someone else to do the work, the business owners will soon be doing it themselves. NiSource will soon be able to empower knowledge workers to regularly contribute to their sites, and, as a result, NiSource will be able to streamline their content creation process while saving valuable time.

"The word "content" describes a wide range of interlinked asset types, including text, graphics, application code, documents, metadata, hyperlinks, and media files," said Jack Jia, CTO of Interwoven. "To accommodate the variety and size of assets as well as number of contributors, Interwoven's scalability was critical for NiSource because it can enable multiple contributors to create content for numerous sites - resulting in increased employee productivity."

Content collaboration allows enterprises to scale to the number and variety of contributors, frequency of site updates and number and variety of assets. Projects grow to include a total user base numbering into thousands of employees, and as assets easily number into the millions, occupying gigabytes of disk space, Interwoven supports this growth and easily scales without IT involvement or procurement of new hardware or software.
