WINTERTHUR GROUP TO SELL ITS CANADIAN BUSINESS TO AXA CANADA
--------------------------------------------------------------------------------

WINTERTHUR, NOVEMBER 30, 2005 - WINTERTHUR GROUP ANNOUNCED TODAY THAT IT IS 
SELLING WINTERTHUR CANADA FINANCIAL CORPORATION AND ITS WHOLLY OWNED 
SUBSIDIARY THE CITADEL GENERAL ASSURANCE COMPANY TO AXA CANADA INC. -- A 100% 
SUBSIDIARY OF AXA S.A. -- FOR CONSIDERATION OF APPROXIMATELY CAD 310 MILLION. 
THE SALE OF ITS TORONTO-BASED OPERATIONS COMPLETES WINTERTHUR'S WITHDRAWAL 
FROM THE CANADIAN MARKET FOLLOWING THE PREVIOUS SALE OF ITS QUEBEC 
SUBSIDIARY, L'UNIQUE. IT UNDERLINES THE GROUP'S STRATEGIC AIM TO FURTHER 
OPTIMIZE ITS BUSINESS PORTFOLIO. SUBJECT TO REGULATORY APPROVAL, THE 
TRANSACTION IS EXPECTED TO BE COMPLETED IN THE FIRST QUARTER OF 2006. 

The sale of its Canadian subsidiary is in line with Winterthur Group's 
strategic efforts to sharpen its focus and to reduce the complexity of its 
business. "We will continue to review our portfolio in order to concentrate 
our capital and resources on markets that achieve the best balance of growth 
and risk-adjusted returns", commented Leonhard Fischer, CEO of Winterthur 
Group. 

The Citadel's financial results have significantly improved over the last few 
years as a result of a gradual shift towards a more commercial business 
focus, improved underwriting performance and a firmer pricing environment. 
"As the Canadian insurance market is currently undergoing a phase of 
consolidation, we have chosen to accept AXA's attractive offer and to realize 
the value of The Citadel's franchise," stated Christen Schnor, Head of Market 
Group International, Winterthur Group.

The Citadel is a provider of commercial lines and accident and sickness 
insurance across Canada as well as personal insurance throughout Canada 
excluding Quebec. The company offers quality products and services via 
independent brokers and is managed through three primary business segments: 
Commercial Lines, Personal Lines and Accident and Sickness. It employs around 
350 professionals and contributes around 2% of Winterthur's gross premiums 
written. The Citadel posted net income of CAD 10 million for the six-month 
period up to June 30, 2005, and reported total surplus capital of CAD 190 
million as of that date.
