The unaudited condensed consolidated pro forma balance sheet as of September 30, 2007 reflects the following adjustments:

(a) Assets sold and liabilities assumed by Votorantim under the Stock Purchase Agreement. These unaudited amounts represent Zinc Companies assets and liabilities which will be sold to Buyers as if the transaction had occurred on September 30, 2007.

(b) Reflects estimated proceeds to be received at the closing of the sale of Zinc Companies. The sale price of $295.0 million was reduced by an estimated working capital adjustment of $17.0 million and $4.2 million of expenses for estimated transaction-related costs. The unaudited condensed consolidated pro forma statements of operations do not reflect the recognition of these expenses as they are non-recurring in nature; however, these expenses will be reflected in the Company’s historical financial statements when the transaction is consummated. Additionally, there is potential for an additional working capital adjustment. Pursuant to the Stock Purchase Agreement, if the net working capital balance at the time of closing exceeds the target net working capital, as defined in the agreement, then the purchase price will be adjusted upwards in the amount equal to the excess, and if the net working capital balance at the time of closing is less than the target net working capital, as defined in the agreement, then the purchase price will be adjusted downward in an amount equal to the deficiency.

(c) Reflects the difference between the estimated proceeds identified under (b) and the following:

(i) The book value of Zinc Companies net assets sold of $233.7 million.

(ii) Estimated taxes of $43.2 million.

The unaudited condensed consolidated pro forma statements of operations for the nine months ended September 30, 2007 (Successor Company), the period from December 20, 2006 through December 31, 2006 (Successor Company), the period from January 1, 2006 through December 19, 2006 (Predecessor Company) and each of the two years in the period ended December 31, 2005 (Predecessor Company) reflect the following adjustments:

(d) Elimination of operating results of Zinc Companies. These amounts represent the unaudited statements of operations for Zinc Companies for the nine months ended September 30, 2007 (Successor Company), the period from December 20, 2006 through December 31, 2006 (Successor Company), the period from January 1, 2006 through December 19, 2006 (Predecessor Company) and each of the two years in the period ended December 31, 2005 (Predecessor Company).

(e) Reflects the tax effect of the sale of Zinc Companies calculated at the statutory rates of 38% for the nine months ended September 30, 2007 (Successor Company), the period from December 20, 2006 through December 31, 2006 (Successor Company), the period from January 1, 2006 through December 19, 2006 (Predecessor Company) and each of the two years in the period ended December 31, 2005 (Predecessor Company).
