Acquisition to further expand Humana's product portfolio

LOUISVILLE, Ky.--(BUSINESS WIRE)--Sept. 7, 2007--Humana Inc. (NYSE: HUM) today announced it has signed a definitive agreement to purchase KMG America Corporation ("KMG") (NYSE: KMA), a group and voluntary insurance benefits and third-party administration company based in Minnetonka, Minnesota, for cash consideration of $6.20 for each outstanding share of KMG, representing a premium of approximately 36 percent over the average closing price of KMG shares for the past 60 trading days. The total transaction price of approximately $187.7 million (including estimated assumed debt of approximately $50 million) will be financed through a combination of cash and debt.

KMG offers life and health insurance products and services to approximately 1.1 million group and individual members nationwide, including stand-alone stop-loss insurance through group employers for approximately 473,000 members and third-party claims administration and medical management services for approximately 131,000 self-insured members. KMG's revenues for the year ended December 31, 2006 approximated $181 million.

"KMG's capabilities in voluntary products will complement our major medical offerings in both the employer group and individual product lines," said Michael B. McCallister, Humana's president and chief executive officer. "In addition, KMG's approach to both marketing and product distribution fit well with Humana's focus on the consumer. We are looking forward to having KMG as part of our organization."

"KMG America has managed a rigorous strategic alternative review process and could not be more excited about joining the Humana family of companies," said Kenneth U. Kuk, chairman of the board, president, and chief executive officer of KMG. "Our shareholders, producers, and associates will benefit from this affiliation. I feel we have accomplished the objectives we stated when we announced this effort in May 2007."

The transaction is not expected to impact Humana's guidance for 2007 diluted earnings per common share, with accretion of $0.04 to $0.05 per share expected in 2008.

The transaction was unanimously approved by the boards of directors of Humana and KMG. The transaction is subject to customary closing conditions, including the approval by KMG shareholders and the receipt of governmental and regulatory approvals, including the approval of the South Carolina Department of Insurance, and the expiration of all waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. KMG expects to schedule a special meeting of shareholders during the fourth quarter of 2007 to vote on the transaction. The transaction is anticipated to be completed in the first quarter of 2008.
