On February 6, 2006, Lafarge S.A. issued a press release announcing its intention to launch a cash tender offer for all outstanding shares of common stock of Lafarge North America not owned by Lafarge S.A. or its affiliates. Lafarge S.A. stated that it would offer the shareholders of Lafarge North America US$75 per share (the "Tender Offer"). The Tender Offer represents a mere 16.7% premium over the February 3, 2006, closing price of $64.25 per share. Lafarge North America’s common shares traded as high as $70.47 per share as recently as August 2, 2005. The complaint alleges that the Tender Offer price of $75 per share does not adequately reflect the expected growth in the Company’s profitability, in light of its continued growth in sales and profits.

The action is brought on behalf of all public shareholders of Lafarge North America who are threatened with the deprivation of the value of their shares of Lafarge North America common stock. The action seeks to enjoin Lafarge S.A. from depriving Lafarge North America minority shareholders of their equity interest in the Company for inadequate consideration and from usurping the benefits of the expected growth in the Company’s profitability for the defendants’ own benefit. The action also seeks damages in the event the transaction is consummated.
