PRO FORMA FOOTNOTES WITH RESPECT TO THE CAT ACQUISITION


(1)  Reflects the acquisition by CAT of Hamilton Services Limited for $1.6
     million immediately prior to the CAT Acquisition. This acquisition was
     accounted for under the purchase method of accounting.

(2)  Under the terms of the Stock purchase Agreement, dated 25 March, 1998,
     between ACE, CAT and the Shareholders of CAT (the "Stock Purchase
     Agreement"), CAT's ownership in Enterprise Reinsurance Holdings Corporation
     ("Enterprise") was distributed to CAT's existing shareholders prior to the
     acquisition of CAT by the Company in return for CAT shares. This adjustment
     reflects the disposition of Enterprise for $69 million. The shares received
     by CAT were retired.

(3)  As part of the financing of the acquisition, ACE borrowed $385 million of
     short-term bank borrowings from its undrawn credit facility established in
     December 1997, and from cash on hand. The interest rate on the short-term
     borrowing was approximately 6%.
     
(4)  Under the terms of the Stock Purchase Agreement, ACE paid a total purchase
     price of approximately $691 million (the total aggregate purchase of $711
     million includes an estimate of CAT earnings for first quarter of calendar
     1998 of $20 million). ACE also incurred direct transaction expenses of
     approximately $3 million.
     
(5)  Under purchase accounting, the total purchase price was allocated to the
     acquired assets and liabilities assumed based on their fair values. The
     difference between the cost of the transaction and the fair value of CAT
     net assets acquired was recorded as goodwill. Based on the purchase price
     paid, ACE recorded goodwill of approximately $217 millions from this
     transaction. This goodwill is being amortized over 25 years.     

(6)  To eliminate CAT's shareholder's equity.

PRO FORMA FOOTNOTES WITH RESPECT TO THE SHARE OFFERING

(7)  On April 14, 1998, the Company sold 16.5 million ordinary shares for net
     proceeds of approximately $605.9 million. A portion of the proceeds was
     used to repay the $385 million of short-term bank borrowings used to
     finance the CAT Acquisition (see note 3 above).
     
PRO FORMA FOOTNOTES WITH RESPECT TO THE TARQUIN ACQUISITION

(8)  This adjustment reflects the accrual of the costs related to the
     acquisition and the related reduction of shareholders' equity.
