(b) In the integration and planning activities, Aleris has identified certain cost savings that are based upon assumptions related to cost reductions that management believes are achievable through the integration of Corus Aluminum. Management currently estimates that, on a pro forma basis, these annual cost savings would have comprised the following:

	Estimated cost savings per annum
Manufacturing	$	10.0
Metal sourcing		5.0
Non-metal purchasing		5.0
Shared services		5.0
Total	$	25.0

(c) In connection with the acquisition of certain assets of Ormet in which Aleris acquired the assets, including certain customer contracts, of the Hannibal rolling mill shutdown by Ormet, management intends to transfer approximately 125 million pounds of business to the Lewisport, Kentucky rolling mill, which will leverage the Company’s fixed cost base while expanding its product offering into tread sheet and bright sheet. Management expects to realize $21.7 million of additional EBITDA during 2006 as a result of this acquisition and estimates that $11.0 million was realized during the first half of 2006. Pro forma Adjusted EBITDA for the twelve months ended June 30, 2006 includes the incremental $10.7 million expected to be realized during the remainder of 2006 while pro forma Adjusted EBITDA for the year ended December 31, 2005 includes the entire $21.7 million expected to be realized.
