Ace Limited To Terminate Shareholder Rights Plan

Hamilton, Bermuda: June 9, 2008 – ACE Limited (NYSE: ACE) announced today that it will terminate the ACE Limited shareholder rights plan in conjunction with the Company’s redomestication to Switzerland. This termination will be accomplished by an amendment accelerating the final expiration date of the plan to the date of the de-registration of the Company in the Cayman Islands. The amendment will become effective after the Company’s shareholders approve the Company’s re-domestication from the Cayman Islands to Switzerland, which is being voted on at the Company’s 2008 Annual General Meeting commencing on July 10, 2008. Assuming those proposals are approved, it is currently contemplated that the de-registration of the Company in the Cayman Islands will occur on or about July 15, 2008. The Company has reserved the right to revoke this termination amendment prior to its implementation. The rights plan previously had been scheduled to expire on June 1, 2009.
