3 First Half Highlights Solid first half performance. Achieved net sales growth of 16.1% including 2.6% price increase; Adjusted EBITDA was $346.7M, up 12.7% vs. first half ‘07. Achieved 19.3% Adjusted EBITDA margin. On a constant currency basis, net sales growth was 7.0% and Adjusted EBITDA growth was 2.8% vs. first half ‘07. Adjusted EBITDA increase primarily driven by strong performance in Specialty Chemicals and Advanced Ceramics.

4 First Half Highlights (continued) Slowdown in construction-related businesses in the US and parts of Europe negatively impacted results in Performance Additives. Increased competition due to unfavorable currency rates negatively affected volumes and selling prices in Titanium Dioxide Pigments. Rockwood entered into agreement with Kemira Oyj to form a joint venture focusing on specialty titanium dioxide pigments. In July 2008, Rockwood entered into agreements to acquire Nalco’s Surface Treatment business and Holliday Pigments, a leading producer of ultramarine blue pigments.
