At the Annual General Meeting on June 3, 2010, shareholders approved payment of a dividend of €1 per share and the option to receive the dividend in cash or in stock. Shares allotted in payment of stock dividends will be issued at a price of €28.58, reflecting the maximum 10% discount. This price is equal to 90% of the average of the opening prices quoted for Saint-Gobain shares over the 20 stock market trading sessions preceding the June 3, 2010 Annual General Meeting less the amount of the dividend (€1), rounded up to the next euro cent. You will receive by post, on or after June 9, a form indicating the number of shares that may be purchased. The form will be sent to you (i) by your bank or broker if you hold bearer shares and/or registered shares recorded in the register kept by your bank or broker, or (ii) by BNP Paribas Securities Services if you hold registered shares recorded in the Company's share register. The completed and signed form should be returned to your bank or broker or to BNP Paribas Securities Services as appropriate.
