such forward-looking statements are based upon reasonable assumptions, there can be no assurance that its

expectations will be realized. "Forward-looking statements" consist of all non-historical information, including

the statements referring to the prospects and future performance of Rockwood. Actual results could differ

materially from those projected in Rockwood’s forward-looking statements due to numerous known and

unknown risks and uncertainties, including, among other things, the "Risk Factors" described in Rockwood’s

• The commitment and acceptance of eco cars is driven by the need to ensure independency from crude oil, and the reduction of greenhouse gases.

• Car manufacturers prefer long-term testing rather than immediate start of mass production.

• Most reports estimate the number of eco cars in 2020 in a range of 5 to 7 million.

• Battery development is still in progress, especially for pure electric vehicles and requires modified high sophisticated products.

• Recycling will play a more and more important role.

Market for Eco Cars should develop steadily

• Most reports estimate the number of eco cars in 2020 in a range of 5 to 7 million

Worldwide Lithium Resources• Current estimates of worldwide Lithium resources total

approx. 30,000,000 tons Lithium. or 160,000,000 tons Lithium carbonate)*

• Reserves in active or proposed operations total 14,000,000 tons.(or 74,000,000 tons Lithium Carbonate)*

• Current worldwide demand is approx. 23,000 tons Lithium. (or 122,000 tons Lithium carbonate)*

Main sources are:• Brines from Salars• Ore (Spodumene, Hectorite, Jadarite)• Geothermal- and Oilfield Brines

There is enough Lithium

• All existing producers have announced significant capacity increase over the next years

• In total there are more than 50 active exploration projects worldwide covering all three main sources.
