ALERIS CORPORATION 2010 EQUITY INCENTIVE PLAN FORM OF NON-EMPLOYEE DIRECTOR RESTRICTED STOCK UNIT AWARD AGREEMENT

TO: __________

FROM:    Aleris Corporation

Re:    Restricted Stock Unit Award

I am pleased to report that you have been granted Restricted Stock Units of Aleris Corporation (the “Company”). Some important information about your Restricted Stock Units is set out in this Award Agreement. The Restricted Stock Units were granted under the Company’s 2010 Equity Incentive Plan (the “Plan”), a copy of which ________________________. The Restricted Stock Units are subject in all respects to the terms and conditions of the Plan.

1.    Key Terms.

(a)    The Restricted Stock Units: Your Restricted Stock Units (or “RSUs”) will be credited to a separate account maintained for you on the books of the Company (the “Account”). On any given date, each Restricted Stock Unit will correspond to one Share.

(b)    The RSU Shares: Common stock of the Company, par value $0.01 per share.

(c)    Grant Date: ________

(d)    Number of Restricted Stock Units: _____________

(e)    Vesting: Subject to your continuous service as a member of the Board and the Board of Directors of Aleris International, Inc. (collectively, the “Boards”) from your Grant Date through each applicable vesting date, your Restricted Stock Units will vest as follows: ______________

___________________________________________________________________________.

However, if the stockholders of the Company do not re-elect or re-appoint you to the Boards, or if they remove you from service on the Boards (in either case, despite your willingness to continue to serve) prior to the date the Restricted Stock Units vest, then any unvested Restricted Stock Units shall vest in full upon the date your service on the Boards ends.

(f)    Change of Control: If you are serving on the Boards at the time of a Change of Control, your Restricted Stock Units will vest to the extent necessary to make the cumulative percentage of the Restricted Stock Units awarded hereunder that has become vested as of such Change of Control at least equal to the percentage by which the Initial Investors have reduced their combined Common Stock interest in the Company. This percentage will be measured by

comparing the number of Shares acquired by the Initial Investors on the Effective Date and still held immediately following the Change of Control to the number of Shares they held as of the Effective Date (to be adjusted for stock splits, stock dividends, and the like). If the Initial Investors’ combined Common Stock interest in the Company is reduced by 75% or more, then your Restricted Stock Units will vest in full. By way of example and for illustration purposes only, if there is a Change of Control when 50% of the Restricted Stock Units are vested and the Initial Investors reduce their combined Common Stock interest in the Company by 70%, then an additional 20% of the Restricted Stock Units shall vest upon the Change of Control, and, subject to Section 11 of the Plan, the remaining 30% of the Restricted Stock Units shall continue to vest in accordance with Section 1(e) hereof.

(g)    Dividend Equivalent Rights: You will have Dividend Equivalent Rights on your Restricted Stock Units. A Dividend Equivalent Right is the right to receive, for each Restricted Stock Unit, a payment equivalent to any dividend or distribution made in respect of the Shares underlying your Restricted Stock Units. If the Dividend Equivalent Right relates to a dividend paid in Shares, such Dividend Equivalent Right will be paid to you by multiplying the number of Restricted Stock Units in your Account on the dividend record date by the number of Shares payable as a dividend on a Share. The payment of a Dividend Equivalent Right with respect to any Restricted Stock Unit will be paid to you (without interest) if and when actual holders of the Shares receive their dividends or distributions.

2.    Settlement. The Restricted Stock Units credited to your Account will be settled by the Company within ten (10) days after they vest (and, upon such settlement, will cease to be credited to your Account). At the time of settlement, the Company will issue you a number of Shares equal to the number of Restricted Stock Units that just vested (such Shares, the “RSU Shares”). The Company will in its sole discretion determine the appropriate manner of dealing with fractional shares, including cancellation without payment. The Company will enter your name as a stockholder of record on the books of the Company with respect to the RSU Shares so issued. As a condition to the settlement of your Restricted Stock Units, the RSU Shares shall be subject to all of the terms of the Stockholders Agreement. By signing below, you will have agreed to become a party to, and be bound by, the Stockholders Agreement on the first day that you acquire any RSU Shares pursuant to this Award Agreement.

3.    Early Termination of the Restricted Stock Units. Except as otherwise set forth in Section 1(e) of this Award Agreement, if your service on the Boards ends for any reason, your unvested Restricted Stock Units shall be forfeited without further consideration. In addition, your Restricted Stock Units will terminate upon any cancellation, termination or expiration implemented by the Committee under Plan Section 11 (adjustments upon certain corporate transactions).

4.    Company Call Right. After your Board service ends, the Company shall have the right, but not the obligation, to purchase any RSU Shares held by you (the “Call Right”). This Call Right may be exercised, in whole or in part, from time to time, by the Company providing written notice to you expressing its intent to exercise its Call Right and establishing a call settlement

date of not earlier than six (6) months after you acquired the Shares being called. If the Company exercises the Call Right, as consideration for the RSU Shares purchased by the Company, you will be paid the Fair Market Value of the RSU Shares on the call settlement date.

5.    Restricted Stock Units Subject to Plan and Stockholders Agreement.
