JOINT PRESS RELEASE

                PROPOSED MERGER BETWEEN GAZ DE FRANCE AND SUEZ

      EMERGENCE OF A EUROPEAN LEADER IN ENERGY AND ENVIRONMENTAL SERVICES


     o    Revenues of (euro)64bn in energy and environmental services

     o    An exceptional dividend of (euro)1 per Suez share, i.e. (euro)1.25bn

     o    Merger on a one share for one share basis

     o    (euro)500m of synergies per year


PARIS,  27  FEBRUARY,  2006 - The Board of  Directors  of Suez,  which met on 25
February  2006,  and the Board of  Directors  of Gaz de France,  which met on 26
February 2006, have approved a proposed friendly merger between the two groups.

The proposed  merger builds on existing  cooperation  and is the result of talks
between the two companies, which began a few months ago.

The merger  will be  preceded  by the  payment  of an  exceptional  dividend  of
(euro)1.25  billion by Suez to its shareholders,  equivalent to (euro)1 per Suez
share.

The exchange  ratio in the merger after the proposed  dividend will be one share
for one  share.  This  exchange  ratio  represents  a premium  for Gaz De France
shareholders of 3.9% on the basis of the average stock price over the last three
months, as of 24 February 2006.

Terms of  governance  of the new  entity,  currently  being  finalised,  will be
communicated to the market as soon as they are completed.







A EUROPEAN CHAMPION, WORLD PLAYER IN ENERGY AND ENVIRONMENT

The new group,  with revenues of (euro)64  billion,  will become one of Europe's
leading players in energy and environmental services.

This  transaction  fully meets the strategic  ambitions of the two groups,  thus
facilitating their accelerated  implementation.  The new group will benefit from
an unrivalled  position in terms of complementarity  of skills,  employee talent
and quality of assets.  The new group,  with a strong  Franco-Belgian  identity,
will be  positioned as one of the global  leaders in the energy and  environment
sectors.  The energy asset portfolio,  primarily  located in France and Belgium,
will allow it to benefit fully from the gas-electricity  convergence (gas supply
for  electricity  generation,  dual  energy  offer  of gas  and  electricity  to
customers)  and to gear up to serve the fully  liberalized  energy market on 1st
July 2007 successfully.

The merger  between the two companies  will create a European  leader in gas and
liquefied  natural  gas (LNG) with a secure,  diversified  and  flexible  supply
portfolio. In an increasingly  energy-dependent Europe, the critical size of the
new group will make it a natural partner of large  producing  countries and will
favour the  emergence of major energy  projects.  The new group will continue to
implement  a  dynamic  development  policy  in its  exploration  and  production
activities. The combination of the industrial and commercial know-how of the two
groups in the areas of energy and the environment  will permit the new entity to
compete on equal terms with the main players in a fully liberalised  market, for
the benefit of end-users.

With strong positions in its domestic markets,  France and the Benelux,  the new
group will have the necessary  financial and human  resources to accelerate  its
international development.

The new group  will  become  the  fifth-largest  producer  of  electricity,  the
operator  of  the  largest  European  gas  transport  and  distribution  network
benefiting  from  significant  storage  capabilities,  and  the  leading  energy
services   provider  in  Europe,  as  well  as  a  world  leader  in  water  and
environmental services.



AN ATTRACTIVE PROJECT FOR ALL SHAREHOLDERS

The new group, with an increased weight in the stock market indices, will become
a key stock market player in the utilities sector.

The proposed merger is expected to generate  significant  synergies in the short
and medium term.

     In the short  term,  it is  expected  that the  group  will be  capable  of
generating  (euro)500  million in  operational  synergies per year before tax. A
significant  portion  of  these  synergies  is  expected  to be  generated  from
optimized supply strategies (portfolio optimisation,  reduced procurement costs,
increased  LNG  trading).  The  remainder  will  come from  dual-energy  offers,
primarily in France,  from the  optimisation of energy services and from savings
on non-energy related purchasing. These synergies are expected to be realized in
equal instalments over three years.

In the  longer  term,  additional  synergies  are  expected  to result  from the
optimisation of the group's investment  programme and the development of revenue
synergies.  The carry  forward  of  existing  tax  losses  will  permit  further
substantial savings.


A FAVOURABLE TRANSACTION FOR THE STAKEHOLDERS OF BOTH GROUPS AND JOB CREATION

This  balanced  transaction  between  the two groups will not  generate  any job
losses.  It will provide the group with  sufficient  resources and scale for the
ambitious development which generates new jobs.

The public  service  mission of Gaz de France will be continued and  maintained.
The status of the  employees  of Gaz de France and Suez will not be  affected by
this transaction.

This  project has the support of the French and Belgian  governments,  which are
important  partners for both groups in the energy and environment  sectors.  The
commitments  made  by  Suez  to  the  Belgian  government  at  the  time  of the
acquisition of Electrabel will be fully respected, in particular the development
plan for the LNG terminal at Zeebrugge.




After  confirmation of the exchange ratio by the COMMISSAIRES AUX APPORTS,  this
merger  will  be  submitted  for  approval  by the  Extraordinary  Shareholders'
Meetings of both companies,  after having received the specific  approval of the
COMMISSION  DES  PARTICIPATIONS  ET TRANSFERTS  and the  applicable  competition
authorities.

This proposed merger will be presented  beforehand to the representative  bodies
of the employees.

As announced by the French Prime Minister,  the Government will, in the shortest
time frame possible,  submit to Parliament a modification of the law of 9 August
2004, allowing a change in the minimum level of the government's ownership.

The transaction is scheduled to be completed in the second half of 2006.
