SUNNYVALE, Calif. -December 5, 2003- Interwoven, Inc. (Nasdaq: IWOV), the world's next-generation enterprise content management (ECM) company, today announced that Canada Post, Canada's national postal service, has selected Interwoven to underpin its Internet site, www.canadapost.ca, as well as its national employee portal, Intr@post. With Interwoven, Canada Post anticipates improving communications, via the intranet, among its 55,000 employees located across Canada, as well as providing timely information to the more than 31 million individuals and businesses that rely on its Internet site annually for up-to-date mailing and online business service needs.

Interwoven to Help Deliver Information to Millions of Canadapost.ca Visitors

Canada Post has been delivering information, products and services to its customers through its corporate Website since 1996, and currently receives more than 40,500 visits per day. The amount of information processed and deployed to the Canada Post Website has been increasing substantively. There has been an estimated 72% growth in visits in the last six months of 2002 versus the first six months of 2002, and a 49% increase from the last six months of 2001 versus the last six months of 2002.

"Maintaining the Canada Post Website efficiently is challenging," said Gary Allen, Web Operations director, marketing, for Canada Post. "A long delivery life cycle, meeting prioritized customer expectations, and dealing with the occasional bottleneck are key drivers of the challenge. Process improvements, supported by software tools, are essential to sustaining growth and freeing up resources to focus on Canada Post's marketing vision - which is why we are so excited about launching the Interwoven project to underpin our site."

Some of the current challenges faced by the Web Operations team at Canada Post include:
- Web Operations currently supports content updates for approximately 40 business units;
- Auditing is currently a manual process, and the team relies on the request database, eMail, word of mouth, and file properties to obtain audit results;
- Currently the software that drives deployment is installed on one desktop. If this desktop fails, publishing date-sensitive information can be seriously impacted;
-To publish deployment and request statistics, the team assembles several Excel files into one master summary report;
- Versioning content is not performed automatically. Prior to replacing new content, old content is manually versioned.

With Interwoven, empowering users to create their own content will contribute greatly to reducing the content delivery lifecycle, and Canada Post has already projected a reduction in this lifecycle by 50% in the first year of operation. Interwoven OpenDeploy Distribution Server software will solve the critical deployment challenges, and Interwoven TeamSite Content Server software's versioning and rollback capabilities will take days off the manual processes currently in place to ensure necessary corporate governance of content. Finally, the Web Operations team expects to improve overall internal communications and workflow, maintain same day service or faster for urgent, high-priority requests, and free up and re-task resources.

Intr@post - Demanding Distributed Ownership and Content Control

For Canada Post, the Intr@post portal is a primary communications channel supporting strategic corporate direction and employee needs.

"Communicating business strategies and sharing corporate information with employees in a timely, credible, and easy-to-use source like Intr@post supports our corporate priority of 'Making Our Employees a Competitive Advantage,'" said Barbara Stanyar, general manager, Communications, at Canada Post. "With Interwoven, we saw an opportunity to strengthen this communication channel to provide even more relevant, consistent, and up-to-date information to our employees with greater efficiency."

Intr@post currently reaches over 10,000 employees at 23 major mail-processing plants, 10 administrative offices, 500 retail sites and more than 500 letter carrier depots. The site tracks some 15,000 user sessions per workday, up 60% from the same period in 2002 and up 180% from 2001, when it rolled out nationally. Success came quickly due to a strong communications focus on business objectives and integration with organizational initiatives, attention to usability and employee feedback, and content management practices strong on enablement and accountability that is shared by a multi-functional work team.

"The efficiencies of the new content management system will assist us in keeping pace with the growing needs and expectations of our national employee base," continued Stanyar.

"Interwoven will allow this work team and regional communications staff to create and manage their own content without technical support, reducing corporate costs and improving the quality of the information on Intr@post."
