2014 General Meeting of Shareholders Amount of dividends and option to receive payment in the form of shares

Vélizy-Villacoublay, France, May 27 2014 – The General Meeting of shareholders of Dassault Systèmes (Euronext Paris: #13065, DSY.PA) the 3DEXPERIENCE Company, world leader in 3D design software, 3D Digital Mock Up and Product Lifecycle Management (PLM) solutions, was held on May 26, 2014 at the registered office. The shareholders present or represented held 74.87 % of Dassault Systèmes’ shares.

All resolutions submitted by the Board were adopted. In particular, the General Meeting approved the financial statements and the consolidated financial statements, including the proposed dividend for 2013 amounting to €0.83 per share and decided to offer each shareholder an option to receive payment of their dividend in the form of new Dassault Systèmes’ shares.

The issuance price of the new Dassault Systèmes’ shares to be delivered in payment of the dividend is €88.66. This price is equal to the average of the closing prices quoted on the regulated market of NYSE Euronext Paris during
the 20 stock exchange sessions preceding the General Meeting of Shareholders, minus the net amount of the dividend and rounded up to the nearest euro cent.

The new shares will be of the same category and carry the same rights as the ordinary shares of the Company which are already listed on the regulated market of NYSE Euronext Paris (Compartiment A - ISIN Code FR0000130650 – DSY). Such new shares will be eligible for dividends with respect to the period starting January 1, 2014.

Shareholders may elect to receive payment of the dividend in new shares between May 30, 2014, and June 13, 2014, inclusive, by sending their request to the financial intermediaries that are authorized to pay the dividend or, for shareholders listed in the direct registered share accounts held by the Company, to its authorized representative (Société Générale, Securities Department, 32 rue du Champ de Tir, CS 30812, 44308F Nantes Cedex 3). If this option is not exercised on June 13, 2014 at the latest, the dividend will only be paid out in cash.

If the amount of dividends for which payment in the form of shares has been chosen does not correspond to a whole number of shares, the number of shares to be received by the shareholder will be rounded up to the next whole number upon the shareholder paying the difference in cash on the day the option is exercised or the number of shares to be received by the shareholder will be rounded down to the next whole number and the shareholder will receive the balance in cash.

Shares will be traded ex-dividend as of May 30, 2014 and dividends made payable as from June 25, 2014, in cash or in shares, depending on the chosen option.

The maximum number of new shares which may be issued for the payment of the dividends in the form of shares is 1,167,335 shares, representing about 0.92 % of the share capital and 0.62 % of the Dassault Systèmes (unadjusted) voting rights calculated on the basis of the share capital and voting rights on May 21, 2014, at 00 h, Paris time.

The voting results will be published on the website of Dassault Systèmes.
