Interwoven Announces Third Quarter 2003 Results

Customer Count Surpasses 1290 with 2% Sequential License Growth

SUNNYVALE, Calif., - October 22, 2003 - Interwoven, Inc. (Nasdaq: IWOV), a world-leading provider of content management for the enterprise, today reported its third quarter results. During the quarter, Interwoven signed 41 new license customers, bringing the Company’s total customer count to 1,292. Revenues for the quarter ended September 30, 2003 were $26.1 million, a decrease of 13% from revenues of $30.0 million for the quarter ended September 30, 2002 and consistent with revenues of $26.2 million for the quarter ended June 30, 2003. License revenues represented 40% of total revenues, and service revenues represented 60% of total revenues, for the quarter ended September 30, 2003. Included in license revenues is $1.1 million from the resale of iManage, Inc. (Nasdaq: IMAN) products, with $687,000 in associated resell costs.

For the quarter ended September 30, 2003, net loss on a GAAP basis was $18.8 million, or $0.18 net loss per share on a basic and diluted basis, compared with a net loss of $86.6 million, or $0.85 net loss per share on a basic and diluted basis, for the quarter ended September 30, 2002. Pro forma net loss was $4.4 million, or $0.04 net loss per share on a basic and diluted basis, for the quarter ended September 30, 2003, which represents a 40% improvement over the pro forma net loss of $7.3 million, or $0.07 net loss per share on a basic and diluted basis, for the quarter ended September 30, 2002.

Pro forma net loss for the quarter ended September 30, 2003 differs from GAAP net loss because it excludes amortization of acquired intangible assets of $657,000, amortization of deferred stock-based compensation of $475,000 and restructuring charges of $13.3 million. For the quarter ended September 30, 2002, pro forma net loss differs from GAAP net loss because it excludes the following expenses: amortization of acquired intangible assets of $732,000, amortization of deferred stock-based compensation of $1.0 million, a one-time

charge associated with goodwill impairment related to past acquisitions of $76.4 million and restructuring charges of $1.2 million.

For the nine-month period ended September 30, 2003, revenues were $77.9 million, a 19% decrease from revenues of $95.7 million for the comparable period in 2002. For the nine-month period ended September 30, 2003, net loss on a GAAP basis was $35.1 million, or $0.34 net loss per share on a basic and diluted basis, compared with a net loss of $116.1 million, or $1.13 net loss per share on a basic and diluted basis, for the nine-month period ended September 30, 2002. Pro forma net loss was $15.8 million, or $0.15 net loss per share on a basic and diluted basis, for the nine-month period ended September 30, 2003, compared with pro forma net loss of $22.4 million, or $0.22 net loss per share on a basic and diluted basis, for the nine-month period ended September 30, 2002.

Pro forma net loss for the nine-month period ended September 30, 2003 differs from GAAP net loss because it excludes amortization of acquired intangible assets of $1.5 million, amortization of deferred stock-based compensation of $1.5 million, write-off of in-process research and development of $599,000 and restructuring charges of $15.7 million. For the nine-month period ended September 30, 2002, pro forma net loss differs from GAAP net loss because it excludes the following expenses: amortization of acquired intangible assets of $3.3 million, amortization of deferred stock-based compensation of $4.3 million, a one-time charge associated with goodwill impairment related to past acquisitions of $76.4 million and restructuring charges of $9.6 million.

The Company believes that its pro forma results provide useful information to investors because they reveal the Company’s results excluding non-cash and cash expenses that the Company believes are not indicative of its on-going operations. However, Interwoven urges readers to review and consider carefully the GAAP financial information contained in the Company’s SEC filings and in earnings releases.

“We turned in a solid quarter of improving results. I commend the Interwoven team for our ability to execute as we continue to add world-class companies to our customer list and develop innovative, award-winning products based on our recently-launched Interwoven 6 platform,” said Martin Brauns, chairman and CEO of Interwoven. “We are executing well on our strategy

to deliver the industry’s leading integrated content management platform, and we’ve already integrated both MediaBin and iManage products into our core platform.”

Since the merger announcement with iManage, Interwoven has executed nine new iManage resell deals as a result of collaborative resale efforts between Interwoven’s and iManage’s sales forces, including referrals from iManage’s sales force to Interwoven.

Q3 Highlights

A partial list of key new global customers include: Alticor (Quixtar), Cable & Wireless UK Ltd., CalPERS, Gates Corporation, China General Technology, InnovaPost (Canada Post), Maritime and Port Authority of Singapore, Mobitai Communications, Naval Supply Systems Command (NAVSUP), and New Balance Athletic Shoe, Inc.

Interwoven also received significant customer reorders that included: Cathay Life Insurance, Ericsson, Eurocontrol, Hilton, Novartis, Southern Company, Texas Instruments, and Yamaha.

Corporate Highlights

• On August 6, 2003, iManage and Interwoven announced that they had entered into a definitive agreement to merge in a stock and cash transaction. The combined company will provide the best-integrated platform to manage the complete content lifecycle — from content collaboration and creation, through management, distribution, reuse, archival and disposition. By virtue of its Java technology, comprehensive functionality, enterprise architecture and innovative capabilities such as content intelligence and e-mail management, the new platform is expected to be the industry’s only next-generation enterprise content management platform for the extended enterprise.

• Interwoven and iManage completed significant steps toward closing the merger. On August 29, 2003, the Federal Trade Commission granted early termination of the antitrust waiting period under the Hart-Scott-Rodino Act for the proposed merger of Interwoven and iManage. The registration statement on Form S-4, which includes the joint proxy statement/prospectus for each company’s special meeting of stockholders, became effective on October 9, 2003 and has been mailed to Interwoven and iManage

shareholders. Each company is scheduled to hold a special meeting of stockholders on November 18, 2003, for the purpose of approving the proposed merger, among other things.

• Interwoven announced that, subject to shareholder approval, it would effect a one-for-four reverse stock split of its common stock.

• Interwoven launched the Interwoven Protect Program for compliance and corporate governance. Designed in partnership with leading industry and technology experts, Interwoven Protect enables businesses to address increasingly frequent and stringent content compliance requirements - both internal and external to the enterprise.

• Interwoven announced the opening of its sales office in Mumbai, India.

Products and Solutions

• Interwoven launched the Interwoven 6 Platform in July, the first content management platform to deliver on the usability requirements for the enterprise with the introduction of TeamSite 6.0 Content Server - a major release of Interwoven’s award-winning content management software. TeamSite 6.0 was made generally available at the end of September, and already in less than three weeks more than 100 customers have taken delivery of the new product.

• Interwoven launched the content management industry’s first Service-Oriented Architecture based on Web Services standards - Interwoven ContentServices SDK 2.0 - to enable fast and flexible integration with business applications in the enterprise.

• Interwoven delivered the content management industry’s first self-service solution with iPhrase, enabling organizations to cut support costs significantly by shifting customers and employees to online channels to find information, transact business, and resolve issues.

• Interwoven announced the availability of Interwoven MediaBin Asset Server 3.0 software, the industry’s first integrated digital brand management solution incorporating a service-oriented architecture, facilitating faster time-to-market and brand consistency for global enterprises.

• iManage introduced a set of templates, pre-defined workflows and collaborative workspaces for supporting corporate governance that enable companies to rapidly

deploy processes and controls to help meet requirements of the Sarbanes-Oxley Act. Interwoven announced support for this solution through its current resell agreement with iManage. This solution is designed to deliver the lowest total cost of compliance, driven by rapid deployment, ease of adoption and the ability to reconfigure the solution quickly without extensive reprogramming as processes and regulations change.

• This week at the Gartner ITxpo Interwoven announced the availability of the Interwoven-SBI Brand Portal solution. The new solution not only provides customers with the ability to facilitate quick and easy access to their entire store of brand assets — ranging from corporate and product logos, product photographs, PowerPoint presentations – but also streamlines the process of maintaining and updating these assets.

Promotions and Appointments

During the quarter, Doug Jones was promoted to senior vice president of corporate development.

These statements are based on estimates and information available to us at the time of the release and are not guarantees of future performance.
