PRESS RELEASE

Euronext: LG, NYSE: LR

Paris, May 2, 2006

FIRST QUARTER 2006 sales

RECORD FIRST QUARTER SALES, UP 28.1% TO € 3,772 MILLION

Sales were up 28.1% to € 3,772 million as at March 31, 2006.

This compares to a weak first quarter in 2005.

Volume trends were favorable, reflecting overall good weather conditions and growth in those businesses and markets where the Group is present.

Significant price increases were successfully implemented in an environment of high energy and transportation costs.

The net scope effect was +2.2%.

Foreign exchange variations positively impacted sales by 6.7%.

Bruno Lafont, Chief Executive Officer of the Group, said:

“This strong level of sales confirms the favorable trends for 2006 presented earlier this year. Our management team is focused on implementing our strategic plan, aimed at increasing the profitability of our future growth, streamlining our organization and reducing costs, in order to achieve the best performance levels in our industry, for the benefits of our shareholders.”

CEMENT: €1,822 MILLION (+28.4%)

This very strong growth in cement was achieved through solid volumes favored by robust construction activity in most markets -amplified in Europe and North America by more favorable weather conditions than in 2005- and through significant price increases successfully implemented.

In Western Europe, sales were up overall with good growth in France, Spain and Greece. Volume increases were more limited in Germany and in the UK. Good pricing trends were seen across the region.

Strong demand and favorable weather in North America led to a very significant increase in sales. Average prices increased significantly in both the United States and Canada.

Central and Eastern Europe recorded high levels of activity in most countries, with the exception of Poland, impacted by bad winter conditions.

Strong sales growth was recorded in the Mediterranean Basin, with a solid construction sector and good pricing trends in Jordan, Turkey, Egypt and Morocco.

In Africa, sales increased strongly, benefiting from favorable volume trends across the region, particularly in Nigeria. Prices were up in all markets.

In Asia, sales were up throughout the region. In Malaysia, prices increased strongly from the low level seen in the first quarter of 2005, while volumes declined slightly. India and South Korea continued to enjoy strong growth in volumes. Prices are stabilizing in South Korea. In the Philippines, demand was impacted by a slow construction sector. In China, volumes were substantially up, benefiting from our new plant in Chongqing.

In Latin America, sales were up overall, but with contrasting performance across the region. Very strong volume growth was recorded in Venezuela and Brazil, boosted by a high level of activity in the construction sector, while Chile remained sound. Prices in Brazil fell sharply year on year, leading to a significant decline in sales, and no price improvement is anticipated in the short term.

AGGREGATES & CONCRETE: €1,238 MILLION (+36.3%)

In Aggregates, the first quarter of 2006 continued to show positive trends in our markets. Strong sales growth was seen across Western Europe, driven by solid volumes compared to a contrasted first quarter in 2005, and by successful implementation of solid price increases. Good volume trends were experienced in Aggregates across North America, together with favorable pricing. Other countries posted generally strong levels of volume growth.

In ready-mixed concrete, strong increase in sales was recorded across most of our markets, driven by continued favorable trends in volumes in Western Europe, North America and our emerging markets, together with solid price increases to cover aggregates and cement high costs and mix improvement, driven by the further development of our value-added products.

ROOFING: €304 MILLION (+13.4%)

The Roofing business recorded an increase in sales year on year. In Western Europe, sales were up, with positive trends in most markets.

Strong momentum was maintained in the United States.

GYPSUM: €404 MILLION (+17.4%)

Sales growth was largely driven by significantly higher prices in North America, where volumes also continued to grow.

Sales in Europe were up, driven by increased volumes in all countries. Sales increased in Asia, especially in Thailand, while in South Korea, the construction market is slowly recovering.

STRONG POSITIVE FOREIGN EXCHANGE IMPACT OF +6.7% AMOUNTING TO € 164 MILLION

The positive foreign currency translation impact on sales was generated mainly from the strong appreciation of the US Dollar (€ 47 million), the Canadian Dollar (€ 28 million), the Brazilian Real (€ 12 million), the Chilean Peso (€ 11 million) and the South Korean Won (€ 9 million).

SCOPE CHANGES OF +2.2% AMOUNTING TO € 70 MILLION

Sales from acquisitions amounted to a positive scope effect of € 35 million, largely due to the acquisition of Ritchie in Aggregates & Concrete in the United States (Q4 2005) and to the acquisition of the grinding station of La Esfera in Spain (mid 2005). The positive impact of the termination of the joint venture in Aggregates & Concrete in Spain and Portugal amounted to € 31 million and the creation of the Group’s joint venture with Shui On in Cement in China generated a positive impact of € 9 million. The reduction in sales due to negative scope effects was marginal (€ 5 million).

Lafarge is the world leader in building materials, with top-ranking positions in all four of its businesses: Cement, Aggregates & Concrete, Roofing and Gypsum. With 80,000 employees in 76 countries, Lafarge posted sales of Euros 16 billion in 2005.
