GraphOn Corporation John Dilworth, 1-800-GRAPHON www.graphon.com GraphOn Corporation (OTCBB:GOJO), a leading worldwide developer of thin-client application publishing and Web-enabling software solutions, announced today that it has signed an OEM agreement with Datasul S.A. (Bovespa: DSUL3), a multinational corporation headquartered in Brazil. Under terms of the agreement, Datasul will private label GraphOn's GO-Global for Windows software product to Web-enable their entire portfolio of Windows-based integrated management software applications.

GO-Global is a fast, simple and affordable application delivery solution that provides instant Web-enabled, cross-platform access to centrally-running software applications from any location, platform and operating system. With GO-Global, there is no need to rewrite applications for the Web or deploy complex infrastructure such as Microsoft Windows Terminal Services or Citrix Presentation Server.

"We are very pleased to enter into this technology partnership with GraphOn which will result in direct benefits to our customers," said Edimilson Correa, Datasul's product and technology chief executive. "With GO-Global, our customers will be able to instantly access our software solutions from anywhere using any Web browser running under Windows, UNIX, Linux, or Mac OSX - or mobile devices running Windows Mobile or Pocket PC."

"By incorporating GraphOn's advanced server-centric technology, patented RXP communication protocol, and near-zero-footprint thin clients, Datasul has been able to eliminate the time, money and effort normally required to rewrite existing applications for the Web or port them to new computing platforms," explained Mike Ruggeri, GraphOn's regional sales manager. "And unlike other Web-enabling alternatives, Datasul will be able to retain 100% of their applications' features, functions and branding."
