The Executive, Company and Parent desire to amend the Agreement effective immediately prior to the effectiveness of the 2011 initial public offering of Parent as follows:

1. The last sentence of Section 5(a)(ii) shall be amended to add at the end thereof the following:

;provided, further, however, notwithstanding the foregoing, if termination of employment is in anticipation of or within twelve (12) months following a Change of Control (as defined in the Aleris Corporation 2011 Equity Incentive Plan), the Severance Payment will be paid in a cash lump sum within thirty (30) days following the Date of Termination, to the extent such a payment would be permissible if being made to an executive subject to United States tax under the rules regarding a “short term deferral” within the meaning of Treasury Regulations Section 1.409A-1(b)(4) of the Code and “separation pay plans” within the meaning of Treasury Regulations Section 1.409A-1(b)(9) of the Code or otherwise not subject the Executive to taxes if he were subject to United States taxes under Section 409A of the Code. For purposes of the foregoing, a termination of employment will be deemed to be “in anticipation of” a Change of Control if such termination is for the principal purpose of avoiding or evading the Company’s or Parent’s compensation obligations that would arise upon a termination following a Change of Control.”

2. The penultimate sentence of Section 5(d) shall be amended to add at the end thereof the following:

;provided, further, however, notwithstanding the foregoing, if termination of employment is in anticipation of or within twelve (12) months following a Change of Control (as defined in the Aleris Corporation 2011 Equity Incentive Plan), the Non-Renewal Payment will be paid in a cash lump sum within thirty (30) days following the Date of Termination, to the extent such a payment would be permissible if being made to an executive subject to United States tax under the rules regarding a “short term deferral” within the meaning of Treasury Regulations Section 1.409A-1(b)(4) of the Code and “separation pay plans” within the meaning of Treasury Regulations Section 1.409A-1(b)(9) of the Code or otherwise not subject the Executive to taxes if he were subject to United States taxes under Section 409A of the Code. For purposes of the foregoing, a termination of employment will be deemed to be “in anticipation of” a Change of Control if such termination is for the principal purpose of avoiding or evading the Company’s or Parent’s compensation obligations that would arise upon a termination following a Change of Control.”
