WebEx to Acquire Intranets.com

On-Demand Collaboration Leaders Combine; Will Offer Complete Real-Time and Asynchronous Web Collaboration Solutions

SANTA CLARA, Calif., August 1, 2005 - WebEx Communications Inc., (Nasdaq: WEBX), the leading provider of collaborative web meeting applications, today announced that it has entered into a definitive agreement to acquire privately held Intranets.com of Burlington, Massachusetts. With more than 300,000 paying subscribers and 10,000 corporate sites, Intranets.com is the leading provider of asynchronous collaboration applications for small and medium-size businesses. The acquisition will enable WebEx to offer companies of all sizes a comprehensive, cost-effective, on-demand web collaboration suite that includes both real-time and asynchronous capabilities.

Intranets.com provides an on-demand suite of asynchronous collaboration tools for team collaboration, project management, and partner coordination. The integrated suite includes secure document sharing, group scheduling, task management, database applications, discussion forums and contact directories. Traditionally, these sophisticated capabilities were only available from enterprise software providers and required significant IT budgets and resources to deploy and operate. With its powerful on-demand suite, Intranets.com has made these productivity tools available to small and medium businesses for a fraction of the total cost of a software-based implementation.

Under the terms of the agreement, WebEx will pay approximately $45 million in cash, subject to certain adjustments, for Intranets.com which will become a wholly owned subsidiary. The acquisition has been unanimously approved by the boards of directors of each company. The acquisition, which is expected to close in the third quarter of 2005, is subject to customary closing conditions.

"This acquisition secures our position at the nexus of two fast-growing market segments: web collaboration and on-demand applications," said Subrah Iyar, CEO of WebEx. "Companies of all sizes are realizing the cost and productivity benefits of on-demand solutions. WebEx is uniquely positioned to provide a new generation of web collaboration solutions that are affordable, easy-to-use and can be deployed immediately."

Intranets.com has had 49 consecutive months of growth. Last year, Intranets.com was named to the Inc. 500 list of the fastest growing private companies and its collaboration suite was recognized by PC Magazine as an "Editor's Choice" winner.

"This is an excellent opportunity for both WebEx and Intranets.com," said Rick Faulk, CEO of Intranets.com. "With this acquisition, WebEx will now offer market-leading solutions for both real-time and asynchronous web collaboration."

According to research firm IDC, on-demand software revenues exceeded $1.4 billion in 2004. An April 2005 survey conducted by the research firm found that nearly 79 percent of IT professionals have purchased or are currently reviewing on-demand software. IDC believes that the key driver for software-as-a-service is transitioning from cost savings to productivity enhancement as on-demand applications increase specialization, functionality and integration.

Guidance
The following contains forward-looking guidance regarding WebEx's financial outlook. The following statements are based on current expectations.

Assuming closing of the acquisition, WebEx is raising its revenue guidance for 2005 by $3 million to $5 million. The new revenue guidance for 2005 is a range of $303 million to $315 million. The acquisition, when closed, is expected to be dilutive to WebEx EPS by $0.02 to $0.03 in third quarter of 2005 and $0.04 to $0.06 for the full 2005 year. The revised EPS guidance for the third quarter will be $0.25 to $0.28 and for the full 2005 year will be $1.08 to $1.16. In 2006, the transaction is expected to be neutral to slightly accretive to WebEx EPS. The actual EPS guidance is subject to completion of an independent appraisal of the assets acquired and related purchase accounting adjustments later this quarter.
