                  CATLIN ESTIMATES IMPACT OF RECENT HURRICANES

HAMILTON, Bermuda - Catlin Group Limited ('Catlin') has completed an initial
review of the potential financial impact of the four hurricanes (Charley,
Frances, Ivan and Jeanne) that have caused extensive damage in the Caribbean and
the Southeastern United States.

On the basis of the information currently available to Catlin and taking into
account our planning assumptions, the Group estimates that the net impact of
these events on 2004 income before income tax will amount to approximately US$50
million. This estimate is subject to change -- either upwards or downwards -- as 
further information becomes available to the Group.

On 14 September 2004, Catlin announced income before income taxes of US$112.6
million and record net income of US$95.8 million for the six months ended 30
June 2004.

Catlin believes that the losses created by the recent hurricanes will have a
positive effect on rate levels and underwriting discipline worldwide.
