LEXINGTON, Mass.--(BUSINESS WIRE)--June 30, 2003

Centra Software, Inc. (NASDAQ: CTRA), a leading provider of application software and services for real-time enterprise collaboration (RTEC), today announced that it has shipped Centra 7(TM), the first application software to address corporate requirements for enterprise-wide adoption of real-time collaboration solutions. Deployed as both an on-site and ASP solution, Centra 7 enhancements include three major innovations: 1) advanced integration with the user desktop, 2) solutions that address an entire business process - before, during, and after the live collaboration session, and 3) advanced systems architecture to support global enterprise deployments.

"Centra 7 represents the first definitive step made by a vendor beyond developing real-time collaboration 'tools' to becoming a full enterprise-class application solution," said Leon Navickas, chairman and CEO of Centra. "The reality of today's economic environment has forced organizations to find ways to cut costs, accelerate business processes, and improve employee productivity with fewer resources. IT departments are looking to consolidate their expenditures by making more strategic investments in enterprise applications. Centra 7 is the answer for an increasing number of customers who have begun to standardize on Centra as a single-vendor solution for enterprise collaboration."

Centra's ASP and hosted customers will be migrated to Centra 7 over the next few months, with availability for new accounts beginning in July. Centra 7 ships after a successful three-month, in-depth beta program, which included more than 40 unique customers comprised of both on-premises and ASP implementations.

"Centra 7's support for corporate IT requirements, especially regarding security and scalability, is important to us as a global organization," said Mark Eggers, manager of online training for Wyndham International. "We look forward to expanding our training and communications with Centra 7 to all of our employees." Based in Dallas, Wyndham International owns, leases, manages and franchises hotels and resorts in the United States, Canada, Mexico, the Caribbean and Europe.
