September 8, 2010 –New York, NY – Charterhouse Group, Inc. (“Charterhouse”) a New York-based private equity firm, together with Highlander Partners (“Highlander”), a Dallas-based investment firm, and MTS Health Investors (“MTS”), a healthcare private equity firm, announced today that Chamberlin Edmonds & Associates, Inc., one of their portfolio companies, has entered into a definitive agreement to be acquired by a subsidiary of Emdeon Inc. (NYSE: EM), for $260 million in cash.

Headquartered in Atlanta, Georgia, Chamberlin Edmonds is a leading provider of government program eligibility and enrollment services to over 200 acute care facilities in 30 states. Chamberlin Edmonds’ technology-enabled services assist hospitals in lowering the incidence of uncompensated care, reducing bad-debt expense and increasing overall cash flow. Chamberlin Edmonds has a 24-year track record of patient advocacy and guiding uninsured patients through the complex processes associated with securing reimbursement from Medicaid, Social Security Disability, state disability, charity care and other community benefit programs.

Emdeon Inc. is a leading provider of healthcare revenue and payment cycle management solutions. The transaction will be financed through the use of unrestricted cash and borrowings under an amendment to Emdeon’s existing credit facility that will be established simultaneously with the closing of the transaction. In connection with the credit facility amendment, Emdeon has entered into an incremental $100 million financing commitment with Citigroup Global Markets Inc.

Under the investors’ ownership, the Company experienced rapid organic growth through the expansion of its hospital customer base and the launching of complementary service offerings. In addition, the Company implemented process and technology initiatives, which served to automate the process of populating an uninsured patient’s information, resulting in higher approval rates, lower costs per submitted application and greater cash recovery for its customers.

The sale transaction exemplifies the investor group’s approach of partnering with experienced, entrepreneurial management teams and executing well-defined growth strategies while using a prudent amount of debt. C. Taylor Cole, Jr., Managing Director at Charterhouse, William F. Miller, III, Operating Partner at Highlander Partners, Curtis S. Lane, Senior Managing Director at MTS Health Investors and Christopher J. Garcia, Member of the Investor Group and Chairman of the Company, collectively commented, “Chamberlin Edmonds is another example of our consistent strategy of partnering with seasoned executives and providing the financial and strategic resources necessary to help companies realize accelerated, profitable growth. We would like to thank Ulrich and his team for all the hard work and dedication they exhibited in leading Chamberlin Edmonds over the past several years. We are confident that the management team will have continuing success with Emdeon.”

“Chamberlin Edmonds has created a scalable technology-enabled service delivery platform that blends national reach and perspective with local delivery and knowledge,” said T. Ulrich Brechbühl, president and chief executive officer for Chamberlin Edmonds & Associates. “By joining Emdeon, we are significantly better positioned to offer the full suite of tools, technologies, services and expertise required to build an optimized eligibility process, from screening through enrollment and cash recovery, to hospitals nationwide.”
