Share Repurchase

CHATTANOOGA, Tenn. (February 4, 2011) – Unum Group (NYSE: UNM) announced today that it entered into an accelerated share repurchase agreement with Goldman, Sachs & Co. to repurchase $200 million of its outstanding common stock. The repurchase follows the recently announced authorization by Unum Group’s Board of Directors to repurchase up to an additional $1 billion of the company’s common stock and is a component of Unum Group’s overall capital management strategy, as outlined in November 2010.

The total number of shares ultimately repurchased under the agreement will be determined at the settlement of the transaction. Under the terms of the repurchase agreement, Unum Group may receive, or be required to deliver, an additional number of shares of common stock based on the volume weighted average price of Unum Group common stock during the term of the agreement. Any adjustment with respect to the Goldman, Sachs & Co.’s obligation to deliver additional shares will be settled in shares of Unum Group common stock. Any adjustment payable to Goldman, Sachs & Co. will be settled either in cash or common stock. Unum Group expects the settlement of the transaction to occur on or before the termination date of the agreement, scheduled for April 5, 2011.
