                          CATLIN GROUP TRADING UPDATE

HAMILTON, Bermuda - Catlin Group Limited, the international property and
casualty insurer and reinsurer, has updated its estimate of the potential
financial impact of the four hurricanes (Charley, Frances, Ivan and Jeanne) that
caused extensive damage in the Caribbean and the Southeastern United States
earlier this year.

On the basis of the information now available to Catlin and taking into account
planning assumptions, the Group estimates that the net impact of these events on
2004 income before income tax will amount to approximately US$75 million, US$25
million more than announced by the Group on 8 October 2004. The higher estimate
is primarily attributable to delayed notification of losses related to energy
installations in the Gulf of Mexico caused by Hurricane Ivan.

This estimate is subject to change -- either upwards or downwards -- as further
information becomes available to the Group.

Stephen Catlin, Group Chief Executive, said:

'Catlin continues to believe that the hurricane related losses will have a
positive effect on rate levels and underwriting discipline worldwide during the
year-end renewal season.

'Premium rates across all classes of business written by the Group rose by a
weighted average of 1 per cent during the nine month period ended 30 September
2004, although the Group estimates that net premiums earned for the full year
will be approximately 5 per cent lower than has previously been estimated. 
As indicated in the interim results announcement, the Group continues to expect 
that it will earn a superior return on equity for the full year.'

The forecasts relating to the 2002 and 2003 years of account of the Catlin
Syndicate at Lloyd's (Syndicate 2003), which is managed by Catlin Underwriting
Agencies Limited, remain unchanged from those announced at the end of the second
quarter.
