Fourth Quarter 2013 Highlights from Continuing Operations

Fourth Quarter 2013 Financial Highlights from Continuing Operations Net Sales of $347.0 mm - Up 7.8% versus the same period in the prior year primarily due to higher surface treatment volumes, particularly automotive OEM, general industry and aerospace application, as well as higher volumes from the acquisition of the remaining 50% interest in a previously unconsolidated joint venture in India and higher selling prices. Higher volumes of lithium chloride and lithium hydroxide applications were partially offset by lower potash sales. Adjusted EBITDA of $78.2 mm (a) - Down 3.1% versus the same period in the prior year primarily from the impact of lower potash sales, and higher variable compensation costs, partially offset by the higher net sales noted above.share(a) - Up 20.5% versus the same period in the prior year from higher net sales, coupled with lower interest expense. Also, EPS benefited from lower common shares outstandinf due to share repurchases in 2013. (a) Non-GAAPmeasure; see reconcilliation in the appendix
