FOR IMMEDIATE RELEASE

UCI MEDICAL CENTER OFFERS SECURE, WEB-BASED COMMUNICATION AMONG DOCTORS, PATIENTS, AND CALL CENTER

UCI is the second University of California-affiliated medical group and the sixth major medical organization in California to select RelayHealthSM

Emeryville, CA, May 20, 2003 - RelayHealth Corporation, the nation's premier provider of Web-based, doctor-patient communication services, today announced that the University of California, Irvine Medical

Center (UCI Medical Center) will license the full suite of RelayHealth online communication services.
"People throughout the country say they want the convenience of communicating with their physicians online," said Dr. Ralph W. Cygan, CEO of UCI Medical Center. "We selected RelayHealth to help us deliver a convenient, efficient online service that will also protect our patients' personal health information while allowing our patients to use the Internet to improve their ability to communicate with their UCI physicians. Called UCI Online, the new program will save patients time, streamline the communication process, and help our doctors and their staff electronically manage non-urgent medical requests. As partners with RelayHealth, we can ensure that UCI Online continues to evolve and grow to the benefit of our patient and physician communities. This partnership represents another important step in making UCI
Medical Center a health care provider of choice for Orange County and the surrounding region."

Implementation will occur in two phases. During the initial phase, to begin immediately, 40 UCI primary care physicians will use the RelayHealth service to communicate with their patients, staff, and each other.
In the second phase, the RelayHealth service will be integrated to the UCI call center, enabling a seamless, HIPAA-compliant channel to facilitate communication tasks like appointment scheduling and prescription renewals. In addition, UCI will upgrade UCI Online to fully integrate RelayHealth services, including appointment requests, medication refills, lab and test result reporting, referral requests, and the webVisit® online doctor/patient consultation service.

Final results of an independent study issued in January 2003 documented high levels of patient and physician satisfaction with the RelayHealth service, as well as significant health care cost savings associated with the service.

"We are both excited and honored to add UCI to our growing list of large, prestigious medical centers selecting RelayHealth to secure communications between providers and their patients and peers," said Giovanni Colella, MD, president and chief executive officer of RelayHealth. "We look forward to working closely with them to expand the range of online communication services available to patients, and to streamline the communications between the UCI call center and their affiliated medical practices."

UCI Medical Center is the only university hospital in Orange County, offering specialized and primary care services to patients throughout the region. It provides outpatient family health services in Anaheim, Irvine, Orange, Santa Ana and Westminster and has the county's only Level 1 Trauma Center and National Cancer Institute-designated comprehensive cancer center.

UCI Medical Center joins a rapidly growing list of over 15 major medical groups and integrated delivery networks in selecting and licensing the RelayHealth service. Other RelayHealth clients include: Catholic Healthcare Partners (CHP), the largest health system in Ohio and one of the largest not-for-profit health systems in the United States; Community Health Network, an Indianapolis-based integrated delivery network with more than 1,100 affiliated physicians; Pennsylvania's Lehigh Valley Hospital and Health Network, whose Lehigh Valley Hospital has ranked among "America's Best Hospitals" as reported by U.S. News & World Report for seven straight years; Hill Physicians, California's largest Independent Practice Association; and MedStar Health System, one of the nation's largest healthcare systems, located in the Baltimore/Washington, D.C. area.
