PARIS, May 16 /CNW Group/

Lafarge, the world leader in building materials, has today announced that it has successfully completed its acquisition of the remaining shares of Lafarge North America (NYSE & TSX: LAF) that it did not acquire previously through its tender offer that expired on May 12, 2006. The acquisition was made by way of a short-form merger with one of its wholly-owned subsidiaries, and the merger was effective prior to the close of business on May 16, 2006. Lafarge now owns 100% of the shares of Lafarge North America (“LNA”).

Shareholders of LNA who did not tender their shares will receive $85.50 as a result of the short-form merger, and will not receive the dividend previously announced and payable to shareholders of record as of the close of business on May 16.

As the result of the merger, exchangeable preference shares of Lafarge Canada that were not tendered pursuant to a tender offer for such shares that also expired on May 12, 2006 will no longer be exchangeable for shares of LNA, but will be exchangeable for $85.26. Record holders of exchangeable preference shares as of the close of business on May 16, 2006 will be entitled to receive a dividend of $0.24 per share payable on June 1, 2006.

LNA has delivered notices to the United States Securities and Exchange Commission requesting the deregistration of LNA shares and to the New York Stock Exchange and the Toronto Stock Exchange requesting the delisting of LNA shares. Exchangeable preference shares of Lafarge Canada will continue to be listed on the Toronto Stock Exchange.
