Zix Corporation Expands e-Prescribing Contract with Aetna into New Markets; Successful PocketScript Results Lead to Additional 750 Physician Contract

Business Wire, Sept 11, 2006

DALLAS -- Zix Corporation (ZixCorp(R)), (NASDAQ:ZIXI), the leader in hosted services for email encryption and e-prescribing, today announced that it has expanded an e-prescribing contract with Aetna (NYSE:AET), one of the nation's leading diversified health care benefits companies. The expanded contract adds up to 750 physicians in the New York City Metropolitan area; Hartford, Connecticut; and Portland, Maine; following a successful first phase of the e-prescribing program in New Jersey in which ZixCorp deployed 1,000 physicians.

"The initial phase of e-prescribing program with ZixCorp was a success. Across the board we have seen greater-than-anticipated increases in formulary compliance and generic prescribing," said Thomas Howe, M.D., Aetna's New Jersey medical director. "We believe that e-prescribing leads to patient safety and quality improvements as well. We are looking forward to expanding the PocketScript service into the new markets and bringing the value of e-prescribing to additional members and health care providers."

PocketScript improves patient safety and reduces costs by allowing physicians to write electronic prescriptions through a handheld device, and then send them immediately to pharmacies. During the prescribing process, the application provides formulary information, a drug reference guide, and drug-to-drug and drug-to-allergy alerts based on the prescriber's available records.

"We think having an industry leader like Aetna expand our product and services speaks volumes about the value of e-prescribing and reinforces ZixCorp's position as the leader in the e-prescribing market," said Rick Spurr, chief executive officer for ZixCorp.
