Simba Information 2003 Report Recognizes Centra as Market Leader for Second Consecutive Year; Leads Trend Towards Single Vendor Solution for Enterprise Collaboration With Centra 7

Centra Software, Inc. (NASDAQ: CTRA) today announced that Simba Information, a leading market intelligence and forecasting firm, has ranked Centra the top virtual classroom/Web collaboration or "live eLearning" provider for the second consecutive year. The ranking was featured in Simba Information's annual report Corporate Training Market 2003: Forecasts and Analysis, which provides a complete picture of the trends shaping the corporate training market, including eLearning. In an analysis of eight of the leading virtual classroom/Web collaboration companies, Centra led the market for eLearning sales by U.S.-based vendors with a 21.3% market share - re-affirming Centra's continued leadership in this space.

"In a live e-learning and collaboration sector growing increasingly crowded with the entrance of major technology players, Centra continues its established leadership position with a suite of enterprise-tested products rich in functionality and features," said Michael O'Brien, an editor with Simba Information and author of the report. "Users report a high level of satisfaction with Centra for distance learning applications."

In the report, Simba Information highlights the increasing convergence of virtual classroom/Web collaboration and Web conferencing technologies as vendors vie for enterprise-wide opportunities - from virtual classrooms to ad hoc online meetings and collaborative projects. Web collaboration applications are being viewed more strategically as a way to lower costs and drive performance across the enterprise, driving an increasing number of organizations to consider standardizing on a single vendor-solution.

"The report reflects what we are seeing among customers - that tactical and point purchasing of real-time collaboration 'tools' is evolving towards a more strategic investment in 'applications' for the enterprise," said Paul Daly, senior vice president of sales and marketing for Centra. "Collaboration software and service providers will have to meet more stringent corporate requirements and provide deeper integration into existing infrastructure in order to help organizations realize the promise of enterprise-wide collaboration. Centra has demonstrated a strong commitment to the enterprise with the recent release of Centra 7."

Released in May 2003, Centra 7 is the first application software to address corporate requirements for enterprise-wide adoption of real-time Web collaboration. Focusing on the business, information technology and user needs that are critical for successful enterprise-wide deployment, Centra 7 provides key enhancements, including advanced integration with the user desktop, solutions that address the entire business process - before, during, and after the live collaboration session, and advanced systems architecture to support global enterprise deployments.
