                      CATLIN US ESTABLISHES NEW YORK OFFICE

NEW YORK - Catlin Group Limited ('CGL': London Stock Exchange), the
international speciality property/casualty insurer and reinsurer, announces that
Catlin US has established an underwriting office in New York.

The New York office will be staffed by an 11-member professional liability
underwriting team, headed by Senior Vice President John Van Decker. He and the
other members of the team have joined Catlin US from Quanta US Holdings Inc.

The team will underwrite various classes of professional liability and directors
& officers (D&O) liability insurance. The professional liability classes include
coverage for financial institutions, real estate agents, lawyers, accountants
and other professionals.

Catlin US, which is headquartered in Atlanta, underwrites specialty classes of
property/casualty insurance for US clients. Catlin US has also recently acquired
an admitted property/casualty insurance company that will soon begin
underwriting business under the Catlin brand. Besides the New York and Atlanta
offices, Catlin US also has offices in Houston, New Orleans and San Francisco.

Richard Banas, chief executive officer of Catlin US, said:

'I am delighted that John Van Decker and his experienced team of underwriting
professionals have joined Catlin to establish our New York office. Members of
the team have worked together for many years, and have established a very
successful track record. Catlin is already well known in the US as an
underwriter of healthcare liability insurance, and the skills and expertise of
our New York team will strengthen Catlin's position in the broader professional
liability insurance market.'

John Van Decker was formerly president of the Professional Liability Division of
Quanta U.S. Holdings Inc, responsible for all forms of professional liability, D
&O liability and fiduciary liability products. Prior to joining Quanta, he held
various management positions at CNA Financial Corp. and for American
International Group Inc.
