WHEREAS, in connection with this retirement and separation of employment, the parties have agreed to a separation package and the resolution of any and all disputes between them;

NOW, THEREFORE, IT IS HEREBY AGREED by and between Employee and the Company as follows:

1. Resignation. Effective as of the Retirement Date, the Employee shall resign from any offices, directorships, similar positions and other affiliations that the Employee holds or has with the Company, Noranda Intermediate, and their respective subsidiaries, affiliates and related entities (the “Noranda Entities”). A copy of the Employee’s resignation is attached hereto as Exhibit A.

Employee will be eligible to receive a bonus for fiscal year 2010 based upon the Employee’s existing bonus target level, but only to the extent that the Employee’s performance and financial results for the Company for the relevant time period will trigger a bonus in accordance with the terms of the Noranda Annual Incentive Plan. Payment of such bonus shall be made in a lump sum amount following the date the Company determines whether the Employee is entitled to a 2010 bonus under the aforementioned plan and determines the amount of such bonus, but in no event later than March 15, 2011. Employee will be eligible to receive a pro rata bonus amount for fiscal year 2011 based upon the Employee’s existing bonus target level and the portion of the calendar year worked through March 31st, but only to the extent that the Employee’s performance and financial results for the Company for the relevant time period will trigger a bonus in accordance with the terms of the Noranda Annual Incentive Plan as established for 2011. Payment of such bonus shall be made in a lump sum amount following the date the Company determines whether the Employee is entitled to a 2011 bonus under the aforementioned plan and determines the amount of such bonus, but in no event later than March 15, 2012. Employee expressly authorizes the Company to make any necessary deductions, withholding, or other reductions from such amounts.

6. Employee understands and agrees that the payments, benefits and agreements provided in this Agreement are being provided to Employee in consideration for Employee’s acceptance and execution of, and in reliance upon Employee’s representations in, this Agreement, and that they are greater than the payments, benefits and agreements, if any, to which the Employee would have received if Employee had not executed this Agreement.
