Dear Interwoven Customers and Partners,

Welcome to the Autonomy Group.

Today we announced the closing of the acquisition of Interwoven by Autonomy, the clear leader in enterprise search and end-to-end eDiscovery and front runner in Meaning Based Computing. Autonomy Interwoven is now a wholly-owned subsidiary of Autonomy, a publicly-listed company with a $4B market capitalization, which now has more than 2,000 employees and 20,000 customers worldwide.

Acquisition

This acquisition brings together two quality, high performing software companies who share a vision to fundamentally change the way organizations discover, analyze and manage electronically stored information. Interwoven, the de facto standard in web solutions and legal document management, is leveraging Autonomy technology to enable you to understand the meaning of unstructured data. For interactive marketers, web content can now be automatically recommended and dynamically delivered based on understanding content, patterns, behavior, history, and interests. In the legal market, this combination provides a strong link between law firm operations and Autonomy's legal and regulatory usage in corporations. This creates a continuous chain through the entire information management and litigation process, streamlining the processes that occur between the law firm and its clients

It is therefore, not surprising that the industry has responded so confidently to this match:

Roadmap & Autonomy's Commitment

Autonomy is committed to the on-going development and support of Interwoven's products and solutions in line with all currently published Interwoven roadmaps. For the avoidance of any confusion, all products live on, including the complete Web Solutions product suite (TeamSite, Optimost, MediaBin, LiveSite, MetaTagger, OpenDeploy and ControlHub), Professional Services Industry Solutions (PSIS) product suite (WorkSite - aka iManage, Universal Search, Records Manager) and Global Capital Markets product family (EnConnect and Scrittura platform). Autonomy's commitment to continue the development of these products is to ensure that you can continue with planned deployments - without any disruption or need for concern.

"Autonomy will lend far more than a search box to Interwoven customers. Rather, combining Autonomy's meaning-based computing with Interwoven's content management raises profound implications for site design, optimization, customer segmentation, personalization, and analytics. The result is a sort of dynamic, self-optimizing, cross-channel, customer engagement engine."

Jim Murphy, AMR Research, 16th April 2009

"...Autonomy will come closer to the elusive one-stop shop for customer engagement and could potentially offer a great array of consumable approaches for companies of most sizes and budgets...Overall, the acquisition puts Autonomy in a stronger position to help companies deal with the new requirements for the evolved web."

Jim Murphy, AMR Research, 16th April 2009

"Autonomy is buying the one-time leader in the content-management space, expanding its customer base by some 3,000, and enabling dominance of the legal arena at a time when the market is set to boom through increased regulation across all industry verticals,"

Derek Brown,Analyst, Seymour Pierce

"We believe this is a good move by Autonomy and should be taken positively by the market. Autonomy has a good track record of acquiring and integrating companies."

Goldman Sachs, 22nd January 2009

"Web content management and search are obvious bedfellows. Secondly, Interwoven's strongest sector is legal - again a great fit with Autonomy which has made its reputation in compliance and disclosure."
