CREDIT SUISSE GROUP ANNOUNCES CHANGES TO THE CORPORATE GOVERNANCE STRUCTURE 
OF WINTERTHUR GROUP

ELECTION OF NEW BOARDS OF DIRECTORS AT WINTERTHUR

Zurich, May 3, 2005 - CREDIT SUISSE GROUP TODAY ANNOUNCED CHANGES TO THE
CORPORATE GOVERNANCE STRUCTURE OF WINTERTHUR GROUP, IN LINE WITH THE
REPOSITIONING OF THE INSURANCE BUSINESS WITHIN THE COMPANY. THE BOARDS OF
DIRECTORS OF "WINTERTHUR" SWISS INSURANCE COMPANY AND WINTERTHUR LIFE HAVE BEEN
NEWLY ELECTED AND WILL BE CHAIRED BY OSWALD J. GRUEBEL, CEO OF CREDIT SUISSE
GROUP, EFFECTIVE IMMEDIATELY.

Following the announcement by Credit Suisse Group that it would reposition
Winterthur as a financial investment and prepare it for a capital market
flotation, the Group has now decided to adapt the corporate governance structure
of Winterthur to reflect this change of parameters.

The composition of the Boards of Directors of the two Winterthur entities was
previously the same as that of the Board of Directors of Credit Suisse Group.
The decision to establish separate Boards of Directors will enhance supervision
at Winterthur Group and will enable specific insurance issues to be monitored
more closely. The management structure of Winterthur Group will remain
unchanged.

The Boards of Directors, which comprise eight members, will be chaired by Oswald
J. Gruebel, CEO of Credit Suisse Group. Anton van Rossum has been appointed
Vice-Chairman. A list of the members of the Boards of Directors and their
Committees is attached.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION
This press release contains statements that constitute forward-looking
statements. In addition, in the future we, and others on our behalf, may make
statements that constitute forward-looking statements. Such forward-looking
statements may include, without limitation, statements relating to our plans,
objectives or goals; our future economic performance or prospects; the potential
effect on our future performance of certain contingencies; and assumptions
underlying any such statements. Words such as "believes," "anticipates,"
"expects," "intends" and "plans" and similar expressions are intended to
identify forward-looking statements but are not the exclusive means of
identifying such statements. We do not intend to update these forward-looking
statements except as may be required by applicable laws. By their very nature,
forward-looking statements involve inherent risks and uncertainties, both
general and specific, and risks exist that predictions, forecasts, projections
and other outcomes described or implied in forward-looking statements will not
be achieved. We caution you that a number of important factors could cause
results to differ materially from the plans, objectives, expectations, estimates
and intentions expressed in such forward-looking statements. These factors
include (i) market and interest rate fluctuations; (ii) the strength of the
global economy in general and the strength of the economies of the countries in
which we conduct our operations in particular; (iii) the ability of
counterparties to meet their obligations to us; (iv) the effects of, and changes
in, fiscal, monetary, trade and tax policies, and currency fluctuations; (v)
political and social developments, including war, civil unrest or terrorist
activity; (vi) the possibility of foreign exchange controls, expropriation,
nationalization or confiscation of assets in countries in which we conduct our
operations; (vii) the ability to maintain sufficient liquidity and access
capital markets; (viii) operational factors such as systems failure, human
error, or the failure to properly implement procedures; (ix) actions taken by
regulators with respect to our business and practices in one or more of the
countries in which we conduct our operations; (x) the effects of changes in
laws, regulations or accounting policies or practices; (xi) competition in
geographic and business areas in which we conduct our operations; (xii) the
ability to retain and recruit qualified personnel; (xiii) the ability to
maintain our reputation and promote our brands; (xiv) the ability to increase
market share and control expenses; (xv) technological changes; (xvi) the timely
development and acceptance of our new products and services and the perceived
overall value of these products and services by users; (xvii) acquisitions,
including the ability to integrate successfully acquired businesses; (xviii) the
adverse resolution of litigation and other contingencies; and (xix) our success
at managing the risks involved in the foregoing. We caution you that the
foregoing list of important factors is not exclusive; when evaluating
forward-looking statements, you should carefully consider the foregoing factors
and other uncertainties and events, as well as the risks identified in our most
recently filed Form 20-F and reports on Form 6-K furnished to the US Securities
and Exchange Commission.
