LOUISVILLE, Ky.--(BUSINESS WIRE)--Sept. 2, 2008--Humana Inc. (NYSE: HUM) today announced it has completed the purchase of Metcare Health Plans, Inc. ("MHP"), a wholly owned subsidiary of Metropolitan Health Networks, Inc. ("Metropolitan") (AMEX: MDF) - based in West Palm Beach, Florida - for approximately $14 million. The transaction has received regulatory approvals from the Florida Office of Insurance Regulation and the Centers for Medicare and Medicaid Services.

Concurrent with the sale, Metropolitan, through its core Provider Service Network (PSN) business, Metcare of Florida, Inc., has entered into a provider-risk agreement with Humana in the 13 counties listed above to provide care for AdvantageCare customers as well as future Humana customers in these counties. In addition, Metropolitan has expanded its provider relationship with CarePlus - Humana's wholly owned Medicare Advantage health plan - to include these 13 counties.

This transaction is anticipated to increase Humana's 2008 premium revenues by approximately $27 million and is not expected to have any effect upon Humana's full-year 2008 earnings guidance of $4.30 to $4.40 per share.
