Paris, 28 July 2014 – ASSYSTEM S.A. (ISIN : FR0000074148 – ASY, the « Company ») - Following the reverse bookbuilding process launched on 9 July 2014 concomitantly to the launch of an issue of net share settled bonds with an indefinite term convertible into new shares and/or exchangeable for existing shares (ODIRNANE), the Company repurchased on 18 July 2014 2,292,445 net share settled bonds convertible into new shares and/or exchangeable for existing shares, issued on 6 July 2011 and due to mature on 1 January 2017 (the "2017 ORNANE"), representing approximately 54.8% of the 2017 ORNANE initially issued.

The Company carried out a repurchase offer (procédure de désintéressement) from 21 July 2014 to 25 July 2014 inclusive, in order to ensure that all the 2017 ORNANE holders which have not sold their 2017 ORNANE in the reverse bookbuilding process are treated equally. The unit repurchase price of the 2017 ORNANE in the repurchase offer was €25.75, including accrued interests, equal to the unit price set in the context of the reverse bookbuilding process.

The repurchase offer ended on 25 July 2014, resulting in a repurchase of 517,841 2017 ORNANE representing c. 12.4% of the number of 2017 ORNANE initially issued, for a total amount of € 13,334,405.75.

The repurchase offer was centralized by BNP Paribas Securities Services. A unique settlement date with regard to this repurchase offer will occur on 31 July 2014.

The total number of 2017 ORNANE repurchased by the Company in the context of the reverse bookbuilding process and the repurchase offer amounts to c. 67.2% of the number of 2017 ORNANE initially issued. Consequently, 1,234,858 2017 ORNANE, representing c. 29.5% of the number of 2017 ORNANE initially issued remains outstanding.

The repurchased 2017 ORNANE will be cancelled, according to their terms and conditions and in accordance with the law.

The Company reserves the right to continue to repurchase 2017 ORNANE, on or off-market after the repurchase offer. The Company also reserves the right to ask for early redemption of the 2017 ORNANE in accordance with their terms and conditions.
