Endurance Increases Share Repurchase Authorization

Bermuda’s Endurance Specialty Holdings Ltd. announced that its Board of Directors has approved an increase in the number of ordinary shares authorized for repurchase under the Company’s share repurchase program to a total of 18 million shares.

The increase is substantial, authorizing a buy-back of 16 million more shares from the original authorization of two million shares approved by the Board of Directors in February 2007.

The share repurchase program authorizes the repurchase of ordinary shares in open market or privately negotiated transactions, from time to time, depending on market conditions. The share repurchase program is currently authorized to continue until May 2009.
