Thales: new composition of the board of directors

The board of directors of Thales met today prior to the Annual General Meeting of shareholders.

With a view to the implementation of the transaction announced in December 2008, whereby Dassault-Aviation would acquire Alcatel-Lucent's stake in the capital of Thales and become the Industrial Partner to the Public Sector under the terms of the shareholders agreement, the board of directors put an end to the mandate of Mr. Denis Ranque as Chairman & Chief Executive Officer of Thales. The composition of the board of directors was then changed and the new board appointed Mr. Luc Vigneron as Chairman & Chief Executive Officer of Thales.

Following the resignation of certain directors, the board co-opted the following new directors:

• Proposed by the Public Sector :

• − Mr. Luc Vigneron, new Chairman & Chief Executive Officer of Thales, until today Chairman & Chief Executive Officer of Giat Industries, Nexter Systems and Société de Gestion de Participations Aéronautiques (Sogepa)
