ISO Acquires DxCG, Leading Provider of Predictive Modeling Software for Health Care

JERSEY CITY, N.J., May 11, 2004 — ISO announced today it has acquired DxCG®, Inc., a Boston-based provider of analytical software solutions that promote fair and efficient health care. With DxCG's sophisticated solutions, customers more accurately evaluate, plan and budget health care management programs. Terms were not disclosed.

DxCG uses medical and pharmacy claims information to predict health care costs and utilization in order to support health plans, providers and employers as they perform actuarial analyses, structure disease management approaches, manage provider networks and identify members for care and case management programs. The foundations of the DxCG RiskSmartTM software suite are DxCG's Diagnostic Cost Groups (DCG) and RxGroups® predictive models, which are based on more than 15 years of scientific research. DxCG models are used by more than 175 clients to allocate more than $70 billion of health care costs annually. Since 2000, DxCG has provided the exclusive predictive modeling methodology used by the federal government to determine reimbursement rates to providers and health plans participating in the Medicare Advantage program.

"We are thrilled to become a part of the ISO family," said Marilyn Schlein Kramer, president and chief executive officer of DxCG. "ISO has a long history in managing insurance claims databases and delivering sophisticated analytics. ISO's substantial technical resources, financial strength and commitment to the continued development of DxCG predictive methods and applications will significantly strengthen our ability to serve our customers and support our rapid expansion in the market," said Kramer.

Frank J. Coyne, ISO's chairman, president and chief executive officer, said, "We were drawn to DxCG because their models are firmly rooted in sound medical science and represent the most credible predictive methodologies available in the health care market.

"As the leading provider of data and analytics to the property/casualty insurance industry, we are always looking for innovative ways to assist our customers," said Coyne. "We will continue to help health care payors deliver quality patient care while maximizing cost efficiencies, as we explore exciting new applications for DxCG's predictive models, including those within the property/casualty market."

DxCG will continue operating from its Boston offices, led by cofounders Arlene Ash and Randall Ellis and the existing management team under Kramer. Both Coyne and Kramer stressed the transition to ISO ownership would be seamless to existing DxCG customers.
