     HAMILTON, Bermuda--(BUSINESS WIRE)--Oct. 24, 2001--ACE Limited
(NYSE:ACE) announced today that it intends, subject to market and
other conditions, to commence a public offering of approximately $1
billion of its ordinary shares, plus up to an additional $150 million
of ordinary shares to cover over-allotments. Salomon Smith Barney Inc.
(sole book-running manager), J.P. Morgan Securities Inc. and Banc of
America Securities LLC will act as managers for the offering.

    ACE expects to use the net proceeds of the offering of the ordinary
shares to take advantage of opportunities in the global insurance and
reinsurance markets becoming available as a result of recent events which
have depleted industry capital and materially accelerated demand for
insurance and reinsurance. ACE intends to deploy the new capital by, among
other things, expanding its net underwriting capacity, either through
internal growth and/or through acquisitions of lines of business or
companies.

    Copies of the prospectus, including the prospectus supplement, may be
obtained when available from Salomon Smith Barney, Brooklyn Army Terminal,
140 58th Street, 5th Floor, Brooklyn, NY 11220 (telephone: 718-765-6732).

    This press release shall not constitute an offer to sell or the
solicitation of an offer to buy, nor shall there be any sale of these
securities in any state in which such offer, solicitation or sale would be
unlawful prior to registration or qualification under the securities laws
of any such state. A shelf registration statement relating to the ordinary
shares that ACE intends to offer, has previously been filed with, and
declared effective by, the Securities and Exchange Commission. Any offer,
if at all, will be made only by means of a prospectus, including a
prospectus supplement, forming a part of the effective registration
statement.

    The ACE Group of Companies provides insurance and reinsurance for a
diverse group of clients. The ACE Group conducts its business on a global
basis with operating subsidiaries in nearly 50 countries. Additional
