2014 Shareholders Annual Meeting

Change in Governance Structure to a Board of Directors

Paris – 22 May 2014, 5:35 pm CEST – Assystem S.A. (ISIN: FR0000074148 - ASY), a leading innovation and engineering consultancy, today announced the change in its governance to a Board of Directors and the membership of the new Board.

Following on from the successful public offer by HDL Development in the first quarter, Assystem shareholders voted at their Annual Meeting on 22 May to change their company's governance structure from a Management Board and Supervisory Board to a Board of Directors and elected five directors to three-year terms.

The new directors are as follows:

• Dominique Louis, director.
• Gilbert Vidal, director.
• Salvepar, represented by Vincent Favier, director.
• Gilbert Lehmann, independent director.

Dominique Louis warmly thanked the outgoing Supervisory Board members for their professionalism and dedication to implementing Assystem's growth strategy.

The new Board of Directors met the same day and appointed Dominique Louis Chairman and Chief Executive Officer of the Company and Gilbert Vidal Executive Vice President and Chief Financial Officer. It also appointed the members of the Board Committees, with the Audit Committee comprising Gilbert Lehmann, Chairman, and Miriam Maes and Salvepar as members, and the Appointments and Compensation Committee comprising Miriam Maes, Chairman, and Gilbert Lehmann and Salvepar as members.
