Cash offer for BPB PLC (“BPB”) response to BPB's statement on additional capital return

October 5, 2005

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."
