WebEx One of Only Three Companies to Make the List Five Consecutive Years

SANTA CLARA, Calif., February 1, 2007—Demonstrating significant annualized growth, WebEx (Nasdaq: WEBX), the leader in on-demand applications for collaborative business on the web, has made the Forbes 25 Fastest-Growing Technology Companies list for the fifth year in a row. Only two other companies, both WebEx customers, have made this prestigious list five years running.

“Our continued success showcases the strength of the on-demand delivery model and the broad demand for our web collaboration services,” said Subrah Iyar, CEO, WebEx. “For 2007 we are focused on going deeper with our web collaboration suite and wider with our new WebEx Connect on-demand platform and partner ecosystem.”

The 25 technology companies were chosen based on revenue growth over a five-year period. To be eligible for the list, a company must have at least $25 million in sales, 10% annual sales growth for five consecutive years, profitability over the past 12 months and 10% estimated annual profit growth for the next three to five years.
