Business Wire, April 26, 2005

DALLAS -- Zix Corporation (ZixCorp(R)) (Nasdaq:ZIXI), a global provider of secure e-messaging, e-prescribing, and e-transaction applications and services, today announced that Northeast Georgia Health System has renewed its three-year contract for the Dr. Chart(R) online order entry and results reporting service.

Dr. Chart is a Web-based connectivity tool that links laboratories efficiently and securely to the healthcare providers they serve. It enables healthcare providers to initiate lab orders, check medical necessity compliance, and view results rapidly and accurately.

"Dr. Chart is flexible, easily accessible, and enables us to customize our own fields for specific information," said Jo Brewer, administrative director for Northeast Georgia Health System. "An extra bonus is that our collections have seen significant improvement due to legible and complete billing information."

"Before using Dr. Chart, Northeast Georgia Health System incurred 20 to 25 percent incomplete billing information. With Dr. Chart, that number is now less than one percent," said Eric Reynolds, director of Dr. Chart sales and business development for ZixCorp. "The convenience and efficiency that Dr. Chart brings benefits the laboratory, the healthcare provider, and ultimately, the patient."
