CHUBB BOARD DECLARES REGULAR QUARTERLY DIVIDEND
AND APPROVES NEW SHARE REPURCHASE PROGRAM

Warren, New Jersey, December 8, 2005 — The Board of Directors of The Chubb Corporation today declared a regular quarterly dividend in the amount of $0.43 per share payable January 10, 2006 to shareholders of record on December 22, 2005.

The Board also authorized a share repurchase program of up to 14 million shares of the Corporation’s common stock. The shares covered by the new authorization equal 7.0% of the 199.9 million shares outstanding as of September 30, 2005. Purchases will be made from time to time in the open market or in privately negotiated transactions. The authorization has no expiration date. This authorization replaces an existing program approved by the Board on July 24, 1998 to purchase up to 12.5 million shares of which 3,287,100 shares had remained available for repurchase.

“This action reflects the Board’s confidence in the strength of Chubb’s financial condition as well as our commitment to manage our capital efficiently,” said John D. Finnegan, Chairman, President and Chief Executive Officer.
