Compagnie de Saint-Gobain, whose long-term senior debt is rated BBB+ by Standard
& Poor's and Baa1 by Moody's, set yesterday the terms of its new benchmark bond
issue denominated in Euros.


The dual-tranche issue was particularly well received by investors. Due to the
volume and quality of investor demand (orderbook over EUR 6 Bn), the respective
spreads at launch were set at the bottom of the initial price-guidance
(respectively 28bp and 50bp over mid-swap rate on the 5 and 10 year tranche),
and the final size of the bond issue was increased from initial €1.5Bn to
€2.5Bn. This transaction underlines bond investors' confidence in the credit
quality of Saint-Gobain, whose last issuance on the Euro bond market was in May
2006.


Placement was made across a diversified basis of investors, as indicated below:
