Online Learning Initiative Blossoms Into Enterprise-Wide Digital

Collaboration Strategy

Centra (NASDAQ: CTRA) announced today that Cognex Corporation (NASDAQ: CGNX), the world's leading supplier of machine vision systems, has successfully deployed Centra's real-time Web collaboration platform to deliver interactive, online learning and communications to a large global audience of customers and employees. Faced with the introduction of a new, low-cost vision system to customers, Cognex assessed that the cost of each physical classroom course would be disproportionate to the cost of each new system. With Centra, Cognex has been able to reach many more customers over the Internet at a fraction of the cost without sacrificing the quality of its educational services.

"Over the last two years, Centra has enabled us to dramatically increase the frequency and reach of our employee programs, and to accelerate the delivery of critical product knowledge and information to users worldwide," said Cliff Fitzgerald, Senior Manager of Worldwide Educational Services for Cognex Corporation. "Our ability to deliver live Centra sessions in targeted modules, that can be recorded for later viewing, better suits the deadline-driven, diverse nature of our global audience - many of whom take advantage of recorded sessions to ensure comprehension of material delivered in English."

The platform's flexibility, ease-of-use, interactive application sharing, and integrated voice-over-IP capabilities have quickly made Centra-powered collaboration popular in other departments at the company as well. The marketing department has adopted Centra for online meetings and to conduct live Webinars for updating the sales force and application engineers on new products and features. The application engineers have been using Centra's virtual classroom product to demonstrate their products online to customers.

"As soon as people are exposed to Centra, they quickly realize ways the technology could be adopted for use in their jobs," commented Fitzgerald. "Even our IT department is looking at Centra to provide training to regional offices."

Scaleable Software Solution for Enterprise Collaboration

Used by more than 900 companies, government agencies, and universities worldwide, Centra's scaleable software solutions are based on CentraOne(TM), an open and extensible Web collaboration platform. Leveraging the core capabilities of CentraOne, Centra offers a suite of compatible, real-time Web collaboration applications, content composition tools, and knowledge delivery systems that can be quickly installed on-site using Centra's rapid deployment methodology, or conveniently accessed through Centra's secure, full-service ASP. The applications supported by CentraOne - including interactive Web meetings, virtual classrooms, and large-scale conferences - ensure universal access to users through firewalls and proxy servers, and deliver full-performance IP audio conferencing, streaming video, application sharing, and dynamic multimedia over low-bandwidth network connections through a standard browser interface.

"Cognex is a great example of how Centra is being used for both internal and external outreach to customers and employees for a variety of business interactions," said Tony Mark, Centra's President and COO. "Centra helps organizations to realize the full potential of online collaboration technology to connect all segments of their enterprise in a productive, secure and easily accessible online work environment."
