Special Committee of the Board of Directors of Lafarge North America Defers Making
Recommendation on Lafarge S.A. Tender Offer;
Tender Offer Period to Be Extended by Two Weeks

HERNDON, VA, March 6, 2006 — Lafarge North America (NYSE & TSX: LAF), in a Solicitation/Recommendation Statement on a Schedule 14D-9 filed today with the Securities and Exchange Commission, reported that the Special Committee of its Board of Directors has determined that it is unable at the current time to take a position with respect to the tender offer of Lafarge S.A. (Paris Stock Exchange: LG; NYSE: LR) launched on February 21, 2006. The Special Committee stated that this was due to the fact that the Special Committee has not yet had sufficient time to complete a full and deliberate review and evaluation of the material terms and provisions of the tender offer, including the prospects and value of Lafarge North America. At the request of the Special Committee, Lafarge S.A. has agreed to extend the expiration date of the tender offer by a minimum of two weeks such that the tender offer would not expire prior to 12:00 midnight, New York City time, on Monday, April 3, 2006.

As previously disclosed, the Special Committee consists of directors not affiliated with Lafarge S.A. and was formed to review the tender offer. The Special Committee is being assisted by Merrill Lynch & Co., as its lead financial advisor, Simpson Thacher & Bartlett LLP, as its legal counsel, Venable LLP, as its Maryland counsel, and MacKenzie Partners, Inc. as its advisor with respect to shareholder matters. In addition, the Special Committee has also retained The Blackstone Group L.P., as an additional financial advisor, and Osler, Hoskin & Harcourt LLP, as its Canadian counsel.

The Special Committee is continuing its review and evaluation of the tender offer and expects that after it has completed its review and evaluation, it will be able to inform the Lafarge North America stockholders as to its position or recommendation, if any, with respect to the tender offer.

The Special Committee requests that stockholders of Lafarge North America take no action and not tender their shares of Lafarge North America’s common stock with respect to the tender offer at the current time, and instead defer making a determination whether to accept or reject the tender offer until the Special Committee has advised stockholders of its position or recommendation, if any, with respect to the tender offer.
