CASH OFFER FOR BPB PLC (“BPB”)
RESPONSE TO BPB'S STATEMENT ON ADDITIONAL CAPITAL RETURN

Not for release, publication or distribution, in whole or in part, in, into or from Australia, Canada or Japan.

Saint-Gobain notes today's announcement from BPB that it is increasing its proposed return of capital from £350 million to £600 million and that it intends to grow dividends by 88% over the next three years. Saint-Gobain questions whether this is in the best interests of shareholders.

BPB has been keen to stress its desire to create shareholder value through long-term growth. However, its initial response to Saint-Gobain's proposed offer was to incur heavy borrowing to fund a very large share buyback and to offer significantly increased dividends on the remaining outstanding shares. Today, it has decided to mortgage further the future of the company thereby jeopardising not only future growth prospects, but possibly its fundamental stability.

Saint-Gobain continues to believe that this offer would be better discussed in a private forum. Unfortunately, BPB does not want to do so. In light of this, Saint-Gobain believes there are a number of questions shareholders should be asking BPB:

  - If BPB implements this proposed buyback, what will the gearing level be over the next 5 years?
  - Is BPB's dividend level sustainable? What will the future level of dividend cover be?
  - Are BPB shareholders being asked to choose between growth or cash?
  - Is the sale of some of BPB's businesses the first sign that its growth plan will be difficult to finance given this new cash back strategy?
  - Isn't the whole cash back strategy increasing risk substantially for shareholders?

Jean-Louis Beffa, Chairman and CEO of Saint-Gobain said:
"Saint-Gobain believes that substantially increasing dividends and borrowing heavily to fund buy backs does not affect the fundamental value of the BPB business. Our cash offer of 720p per share offers certainty and value for BPB shareholders today."
