Iron Oxide Pigment Value Chain - Overview Iron Oxide can be synthesized using different feedstock (typically iron based waste streams) by using different synthesis processes Finishing including milling, blending, granulating, and liquefying to meet the specific requirements of the end customers Unfinished Pigments come in three base colors (red, yellow and black) which are blended into various colors Raw Materials Copperas Scrap Iron Iron Powder Unfinished Pigments Red Yellow Black Finished Pigments Powder Liquid Granule Synthesis Finishing 67

Iron Oxide Pigments Value Chain - Construction Chinese sourced iron oxide has allowed in-house capacity to focus on higher value-added market segments The manufacturing processes for this group of products typically involve blending and liquefying without the need to invest in chemical reaction capacity. Powder, granules and liquids are different forms of iron oxides to meet the dosing requirements of the customers Unfinished Iron Oxide Internal Sources Other Chinese Suppliers Blocks and Pavers Ready-Mix Concrete Beltsville - Blended powder, Granules Matlock - Blended powder, Granules Walluff – Blended Powder, Granules Los Angeles - Blended Powder, Liquids King of Prussia - Liquids Raw Materials Finishing Applications Shenzhen – Blended Powder, Granules Colton – Blended Powder, Liquids 68

Iron Oxide Pigments Value Chain - Coatings The stringent specifications (color and heat stability) of the coatings applications favor internally manufactured iron oxides The iron oxides produced in these facilities can be further processed into granules and liquids.

Part 2: Lithium Ion Battery Market is growing strongly in existing applications In 2007 over 2.5 Billion Lithium Ion Battery cells for electronic devices have been produced, 66% of the total rechargeable battery market. Historical annual growth rate for Lithium Ion Batteries has averaged over 10% expected growth in the next few years will be in that range. Current major market applications for Lithium Ion Batteries are cell phones and notebook computers. Annual lithium carbonate demand for Lithium Ion Batteries is already over 25 million pounds with Chemetall holding a 40% share of the market. Lithium carbonate is used for the manufacturing of various cathode materials (mainly Lithium cobaltate). 100

Part 2: Lithium Ion Battery Market - new applications in power tools and small application Besides the increasing demand of cellular phones and notebooks, the implementation of new Lithium Ion Batteries for power tools and other smaller applications, e. g. camcorders, video games, PDA, i-Pod are main growth drivers for the next years. The growth potential for power tools with Li Ion Batteries is estimated to be 15% per year. Power tools with Li Ion Batteries now offering similar performance of plug-in and pneumatic models. Originally offered as tools for professionals in 2004, now being introduced in “Do it yourself” commercial use. 101
