Stock Dividend Payment Procedure

At the Annual General Meeting on June 4, 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 €22.83, 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 trading days preceding the June 4 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 10, 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.

Dividend timekine:
'Record date' June 9, 2009
Ex-dividend date June 10, 2009
Dividend reinvestment period June 10 to 24, 2009
Dividend payment and share issuance date July 2, 2009

You may elect to reinvest* your 2008 dividends, by notifying your bank or broker or BNP Securities Services between June 10 and 24. If the option is not exercised within this period, your dividends will be paid in cash only.

If the amount of the reinvested dividends does not correspond to a whole number of shares, you may choose:

- To receive the next lower whole number of shares with the difference paid in cash, 

or

- The next higher whole number of shares by paying the difference in cash when the option is exercised.

Any deductions or withholdings will be made directly from the amount of the dividend by the custodian bank, in the same way as for cash dividends. Social taxes are deducted at the rate of 12.1% from dividends paid to individual shareholders resident in France, who may also elect for income tax to be withheld at source at a flat rate of 18%.

The new Saint-Gobain shares will be issued on July 2, 2009 and will carry rights to the 2009 dividend.

* The option to receive the 2008 dividend in stock is not available to shareholders resident in countries such as Australia, Canada, Italy and Japan, where the resulting share issue would have to be registered with or approved by the local securities regulator. Shareholders resident outside France should enquire about and comply with any local restrictions. No dividend reinvestment requests will be accepted from shareholders in countries where these restrictions apply. Shareholders are responsible for determining the conditions and consequences of exercising the dividend reinvestment option under the local laws of their country of residence. When deciding whether or not to exercise the dividend reinvestment option, shareholders should consider the risks associated with an investment in shares.
