SUNNYVALE, Calif., - July 12, 2004 - Interwoven, Inc. (Nasdaq: IWOV), the world's next-generation enterprise content management (ECM) company, today announced that it has been cited as the market share leader in document management and collaboration among top UK law firms, adding to its leadership among leading North American firms.

Legal Technology Insider, one of the UK's leading legal publications, recently reported in an article entitled, "Interwoven Set to Dominate the DMS [document management systems] Market," that "...Interwoven now has its WorkSite DMS running or due to be installed in 54 of the UK's top 200 law firms, compared with just 42 using Hummingbird. This is in sharp contrast to the autumn of last year when Hummingbird was still in 49 firms and Interwoven only had 41 top 200 sites."

Worldwide, over 280 law firms have switched from competing systems to Interwoven WorkSite to take advantage of its industry-leading functionality. Interwoven WorkSite 8 builds on the proven reliability and market-leading customer satisfaction of WorkSite and adds critical functionality including: e-mail management to capture and file e-mails alongside the documents to which they pertain; caching to enable firms to effectively manage matters across offices; and matter-centric collaboration which transforms the way in which lawyers work with document management to increase productivity and client satisfaction.

In the US, leading law firms that have switched to Interwoven WorkSite, contributing to Interwoven's market share leadership in legal, include Dechert LLP; Holland & Knight LLP; Kilpatrick Stockton LLP; Paul, Hastings, Janofsky & Walker LLP; and Willkie Farr & Gallagher LLP. Interwoven WorkSite adoption is being replicated in Europe, where law firms that have chosen WorkSite include Herbert Smith; Freshfields Bruckhaus Deringer; DLA; Martineau Johnson; Bristows; Stibbe; and NautaDutilh.

Customer Momentum Builds

A representative Interwoven WorkSite customer is Nabarro Nathanson, one of the UK's top five commercial firms, with more than 100 partners and 350 lawyers. Its Brussels office boasts a dedicated European Union and competition law unit, and more than 25% of its business comes from overseas clients. Recently Nabarrao Nathanson decided to switch from its existing DM system to Interwoven WorkSite 8, which will enable the firm to take its core business online and improve collaboration among client-focused professionals, practice groups, and European offices.

"We were very impressed with Interwoven, as the team proved to us it understood our business and made our decision to switch from our previous document management solution painless. We have purchased the latest version of the WorkSite product because it is designed to mimic the way our lawyers work, enabling us to roll the solution out to the desktop with complete confidence that our users will have everything they need to continue their business seamlessly. Additionally, the technical support from Interwoven has been first class and they have already delivered excellent training for our users," said Nick Taylor-Delahoy, chief information officer at Nabarro Nathanson.

Additionally, the UK's ninth largest law firm and member of the UK's "Magic Circle," DLA is also standardizing on Interwoven WorkSite as part of a major overhaul of its e-mail and document management systems. Once WorkSite is fully deployed, all of DLA's 3,600 employees will retrieve, access, edit, and manage matter-related documentation using a centralized electronic repository.

"Perhaps one of the main benefits of Interwoven's software is the ability to access and work on critical matter files from any computer with a connection to the Internet. Furthermore, Interwoven's e-mail management capabilities will have a huge impact on the way the firm operates, resulting in a way that will prove invaluable to our lawyers, who spend several hours a day dealing with e-mail," said Daniel Pollick, IT director at DLA.

Launched in mid-2003, Interwoven's E-mail Management Solution has gained record adoption among leading global law firms. Based on Interwoven WorkSite software, the solution has proven highly effective and has won solid customer support in addressing the industry's urgent need for better e-mail management. Interwoven WorkSite 8, also announced in 2003, leads the market in true support of matter-centric collaboration, which, for the first time, enables lawyers and other professional services practitioners to manage a single complete matter file seamlessly across multiple offices.

"The single greatest testament to the quality of any product is customers voting with their budgets to select it over the competition," said Dan Carmel, vice president and general manager of Legal, Professional Services, and Enterprise Compliance Solutions for Interwoven. "WorkSite 8 allows firms to work in ways not possible with competing systems, and our acknowledged leadership in the UK market is the proof. It is gratifying to see customers embracing matter-centric collaboration and successfully addressing pressing business challenges with our solution."
