Atlanta, GA, May 6, 2002 --- MDdatacor, inc., a medical informatics company that utilizes patent-pending technology to rapidly identify patient populations for clinical trials, approved therapeutics and medical devices, today announced it successfully raised $3 million in a second round of funding.

The current round includes investments from healthcare-focused private investors and a strategic corporate partner, DIANON Systems, Inc. (NASDAQ: DIAN). DIANON, a national provider of cancer and genomic diagnostic services, will market MDdatacor’s clinical database services to its large urology and gastroenterology physician customer base.

“We are very pleased with the success of this financing round. The company is fortunate to secure investors who understand the significant value we provide the pharmaceutical and medical device industries as well as physician practices,” said Blake Whitney, MDdatacor chairman, chief executive officer and president. “Our investors not only provide a source of funding, but also the resources and domain expertise to enhance our ability to scale the business.”

Thomas Phiambolis, M.D., executive vice president of CASEP, a large Philadelphia- based cardiology practice commented, “MDdatacor’s technology accepts my practice’s previously paper-based medical records and turns this information into a searchable clinical database that enables me to quickly identify patients who could benefit from participation in a clinical trial or are medically indicated for a procedure. This information helps me more effectively manage my patients’ healthcare.”
