WebEx On-Demand Application Accelerates Sales Cycles and Increases Sales Productivity

SANTA CLARA, Calif., September 27, 2005—Technology Marketing Corporation’s TMC Labs division has awarded WebEx Sales Center the 2005 Innovation Award from Customer Interaction Solutions magazine. Designed exclusively for sales professionals, WebEx Sales Center from on-demand applications provider WebEx Communications (Nasdaq: WEBX) easily integrates with popular Customer Relationship Management (CRM) applications, and helps companies leverage the web to improve sales productivity.

The TMC Labs Innovation Awards recognize innovative technologies that carve out distinctly new niches, and contribute to the CRM and customer interaction market. WebEx Sales Center will be featured in the November issue of Customer Interaction Solutions magazine.

“WebEx deserves this honor for creating a ground-breaking web sales application that delivers measurable results and extends the value of an enterprise CRM investment,” said Tom Keating, CTO and TMC Labs editorial director. “As an industry leader, I am confident we’ll see other innovative on-demand solutions from WebEx.”
