Unum Group non-executive chairman Fossel retiring;

Ryan named non-executive chairman

CHATTANOOGA, Tenn. (July 6, 2011) – Unum Group (NYSE:UNM) today announced that Jon S. Fossel, 69, is retiring as non-executive chairman of the board of directors. William J. Ryan has been named non-executive chairman of the board of directors, succeeding Fossel. The transition will take effect on September 30, 2011, when Fossel marks five years of service as chairman.

Fossel joined the board in 2002 and has served as non-executive chairman since October 1, 2006. He will provide consulting services to the company after his retirement. Ryan, 67, joined the board in 2004 and is currently chair of the Governance committee and a member of the Finance committee. He retired in 2009 as chairman of TD Banknorth Inc. Previously, he was president, chief executive officer and a director of TD Banknorth Inc. Ryan is also currently a director of Wellpoint, Inc.

“Consistent with my belief that board chairs should rotate periodically, I had indicated to the board earlier this year that I did not intend to serve more than five years as chairman,” said Fossel. “I have decided that this would also be a good time for me to step off the board. The company has achieved a remarkable turnaround, and I am confident it is well positioned for the future.”

“I am pleased to have been chosen by my fellow board members to assume the position of chairman,” said Ryan. “Unum is an exceptional organization with a track record of outstanding performance, and I look forward to working with our strong board and management team to continue to create value for our shareholders. Jon Fossel has served the company well, and we thank him for his years of service.”

Since 2006, Unum’s operating earnings per share have grown at a compound rate of 11 percent and its stock price has significantly outperformed the industry, the S&P 500 and the broader stock market. Unum has also increased its dividend three consecutive years and has completed and/or announced more than $2 billion in share repurchases since 2008.

The company’s increased profitability and financial stability prompted upgrades in its financial strength ratings by S&P, Fitch, Moody’s and A.M. Best over the last three years.
