PerDatum Welcomes Vantage Occupational Health Plan as New MCO Client - March 5, 2000
Columbus, Ohio…PerDatum Incorporated, a Columbus based software development company, is pleased to announce that
Vantage Occupational Health Plan, Inc. has experienced stunning growth and success since implementing PerDatum’s
PROGNOS-MCO software in June of 1999. Vantage has leveraged increased efficiency and capabilities gained from the
new software and a recent statewide expansion into substantial increases in client base and premium.

PerDatum’s PROGNOS-MCO software has played a pivotal role assisting Vantage in streamlining their medical
management processes and increasing the cost effectiveness of their information management practices. PROGNOS’
seamlessly integrated EDI module enables Vantage to instantaneously process new employers into the database and provide
continuous, uninterrupted services to their customers while maintaining full compliance with the Ohio Bureau of
Workers’ Compensation HHP Guidelines.

Mark Tochtenhagen, PerDatum’s President states "The recent success at Vantage is a clear demonstration of our
continuing efforts to assist our MCO clients in competing effectively in Ohio’s market for medical management services.
Our primary objective is to continue providing tools to our MCO clients for increasing efficiency, cost effectiveness, and
quality of service".

On behalf of Vantage Occupational Health Plan, Dale Bugay adds "PerDatum’s PROGNOS software provides the
information management tools required to grow our business rapidly and still maintain the high level of service clients
have come to expect from Vantage. The software makes it easy for us to differentiate our services from competitors with
custom reports, data queries and high quality medical management services. I would recommend PROGNOS-MCO
software to any MCO; it is by far the most comprehensive and cost effective information management solution available to
Ohio’s Managed Care Organizations. Additionally, PerDatum continues to demonstrate leadership and innovation by
offering a fully integrated suite of software products for employers and providers. They are well on their way to providing
employers, medical providers, and service companies with a cost effective method of sharing information and reducing the
overall cost of occupational injuries".

PROGNOS-MCO is an easy-to-use Windows based application which provides capabilities for incident reporting, case
management, treatment planning, fee bill processing, check writing, statistical analysis, and electronic data interchange
(EDI). The system includes a fully integrated EDI module for electronically transmitting and receiving first reports of
injury, medical fee bills, treatment plans, and company information directly with the Ohio Bureau of Workers’
Compensation. Additional advantages offered by the system include a comprehensive security module which provides the
capability to configure custom user accounts for internal staff, as well as for clients requesting direct access to their
employees injury information.

PerDatum also offers software products specifically designed for employers and medical providers. These applications are
designed to improve the efficiency and effectiveness of safety, workers’ compensation, and occupational health programs.
