 WHEREAS, IMCO and Commonwealth Industries, Inc. (“Commonwealth”) have executed and delivered that certain Agreement and Plan of Merger dated as
of June 16, 2004, as it may be amended (the “Merger Agreement”), pursuant to which an indirect wholly owned subsidiary of IMCO will merge with and into Commonwealth whereby Commonwealth will become an indirect wholly owned subsidiary of
IMCO; and 
  
 WHEREAS, the Company recognizes that the proposed
merger involving Commonwealth (the “Merger”) may raise uncertainty and questions among certain management employees of the Company and its subsidiaries, which may result in the departure or distraction of those management employees to the
detriment of the Company and its subsidiaries; and 
  
 WHEREAS,
the Company has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of certain management employees, including the Executive, to their assigned duties without distraction under such
circumstances. 
  
 NOW, THEREFORE, the Company, IMCO Management
and Executive have entered into this Agreement, and on and subject to the terms and conditions hereinafter set forth, do hereby agree as follows: 
  
 1. Employer Entity. As used in this Agreement, the terms “Employer Entity” and “Employer Entities” shall mean IMCO and
IMCO Management, but shall be deemed to include their respective trusts and plans, direct or indirect subsidiaries, successors, affiliates and related companies or entities, regardless of its or their form of business organization, and following the
Merger, shall also be deemed to include Commonwealth and its trusts and plans, direct or indirect subsidiaries, successors, affiliates and related companies or entities, regardless of its or their form of business organization. 
  
 2. Merger Condition Subsequent. In the event the Merger is not
completed by January 31, 2005, then this Agreement shall thereupon be rendered null and void ab initio and of no further force and effect. 
  
 3. Term of Agreement; Termination Date. Unless extended by the mutual written agreement of the parties hereto, the term of this Agreement
(the “Term”) will commence on the date hereof and unless sooner terminated pursuant to the terms hereof, shall expire on December 31, 2005; provided that any provision of this Agreement that by its terms continues after the

 - 1 - 

 
either IMCO and IMCO Management, or Executive, may voluntarily terminate this Agreement during the Term by giving at least sixty (60) days’ advance
written notice of termination to the other parties. The date on which this Agreement terminates is referred to herein as the “Termination Date”. 
  
 4. Services of Executive. Executive will use his best efforts to (i) promote aggressively the value of the Merger and the other transactions

and effort to assist the Employer Entities in the integration of their operations, personnel and administrative functions. 
  
 5. Termination without Cause. Executive shall only be entitled to payment of the severance payments described in Section 6 and Section 8(b)
below in the event that (a) he has complied and continues to comply with his obligations under this Agreement, and (b) he experiences a Termination without Cause (as defined below) on or before December 31, 2005. The term “Termination without
Cause” as used herein shall be deemed to mean (i) Executive’s termination of employment by the Employer Entity for any reason other than for “Cause” (as that term is defined in Section 7 below), or (ii) any party hereto gives
notice of termination pursuant to Section 3 above, and the parties do not agree after the expiration of the sixty (60) day period referred to in Section 3 above to the terms and conditions of Executive’s continuing employment with the Employer

this Agreement and has previously signed and provided the Acknowledgement of Decision Not to Revoke in the form set forth in Exhibit B (which is attached hereto and made a part hereof for all purposes) as set forth in Section 11
hereof, then he shall be entitled to receive, as additional compensation for services rendered to the Employer Entity, the following severance benefits:

sum within ten (10) days following the first date on which all of the events set forth in clauses (i) and (ii) above in this Section 6 shall have occurred. 
  
 (b) Benefits. For the lesser of (1) a period of eighteen (18) months following the Termination Date; or (2) until Executive
obtains comparable coverage under a subsequent employer’s benefit plan or plans, Executive will be entitled to continue to participate on the same basis that he is currently participating as of the date hereof in IMCO’s medical,
hospitalization and dental welfare benefit plans, provided that his continued participation is permitted under the terms and provisions of the applicable plan, program and/or policy. The benefits provided during the period of

 (c) Outplacement Services. The Employer Entity shall
reimburse Executive for up to $20,000 for reasonable costs and expenses of any executive outplacement services selected by Executive. Prior to such reimbursement, Executive shall present to the Employer Entity invoices, and shall provide such other

Share Units (“PSUs”) listed on Exhibit C attached hereto (which is incorporated by reference herein) granted to Executive pursuant to the IMCO 1999 Performance Share Unit Plan (the “PSU Plan”), shall remain
in effect, but shall remain subject to the terms and conditions of the PSU Plan and Executive’s applicable Performance Share Award Agreements, and any payments with respect to such PSUs shall be made to Executive only if and to the extent
provided in the PSU Plan and the applicable Performance Share Award Agreement. 
  
 7. Termination for Other Reasons. If before the end of the Term, (i) the Executive’s employment with the Employer Entity is terminated by the Employer Entity for Cause, or (ii) the Executive
voluntarily resigns from employment under circumstances not covered under Section 5 above, then this Agreement shall terminate on the date of the termination of Executive’s employment with Employer Entity and be of no further force or effect
and the Executive shall forfeit all rights hereunder; provided that any provision of this Agreement that by its terms continues after the termination of Executive’s employment shall survive in accordance with its terms. For purposes of
this Agreement, “Cause” shall be defined as: (1) intentional damage to Employer Entity property; (2) unauthorized disclosure of Employer Entity confidences or trade secrets; (3) commission of a felony under any federal, state, or local
law; (4) any breach of corporate fiduciary duties owed to the Employer Entity; (5) an act of fraud, embezzlement, or theft in connection with his duties or in the course of his employment with the Employer Entity; or (6) refusal to assist in

 (a) Upon the Termination Date, as a condition to payment
under Section 6 hereof, Executive shall execute and deliver the Waiver and Release in the form of Exhibit A, whereby he shall relinquish all right, title or interest in or to any claims, including claims for additional
compensation in any form whatsoever or otherwise, against Employer Entity and the other Released Parties (as that term is defined in such Exhibit A), other than as specifically provided for herein.

continued participation in IMCO’s Annual Incentive Compensation Plan for 2004 and 2005 (provided that (x) IMCO meets its targets as determined by its compensation committee and (y) any such bonus payment will be made at the time or times as
specified in such plan); (3) continued participation in the 2004 and 2005 profit share elective contribution in the Company’s 401(k) plan, to the extent this is allowed by the terms of such plan; (4) payment of accrued and unpaid vacation pay
for 2004 and 2005, as may be applicable, and (5) accelerated vesting of any stock options not vested as of the Termination Date, provided, however, that any such accelerated vesting of any stock options is subject to the prior approval, in its sole
discretion, of the IMCO Compensation Committee. All payments and benefits hereunder shall be subject to any and all applicable withholding or other employment taxes as required by the Employer Entity. 
  
 9. Covenant Not to Sue. Upon the Termination Date, in
addition to his Waiver and Release, Executive agrees that he will never sue any of the Released Parties concerning any claim Executive may have arising from or relating to (a) Executive’s employment with any Employer Entity, (b) the termination
of Executive’s employment with Executive Entity; or (c) any rights as a stockholder of IMCO with respect to events that occurred prior to the date of his Waiver and Release. 
  
 10. New Consideration. Executive expressly acknowledges that he would not be entitled to the
consideration described herein if he did not execute this Agreement and the Waiver and Release, each of which are enforceable against Executive. Executive has no agreement with any Employer Entity that gives Executive any right or claim to the
consideration described herein without first providing a release to any Employer Entity and the Released Parties. Executive acknowledges that there is no practice or policy of any Employer Entity that gives Executive any right or claim to the
consideration described herein without providing a release to each and every Employer Entity and the Released Parties.

intention of the Parties insofar as that is possible. In addition, the Parties hereby expressly empower a court of competent jurisdiction to modify any term or provision of this Agreement to the extent necessary to comply with existing law and to

in writing and deliver a copy thereof to each of the parties by registered or certified mail. 
  

 - 9 - 

 (c) If there is only one arbitrator, his or her decision shall be binding and conclusive
on the parties. If there are three arbitrators, the decision of any two shall be binding and conclusive. A judgment confirming the award of the arbitrators may be rendered by any court having jurisdiction. No action may be taken to vacate, modify,
or correct the arbitral decision or award, except for actions in accordance with the provisions of the Texas General Arbitration Act (Texas Civil Practice and Remedies Code Sections 171.013, 171.014 and 171.015).

shall fail to render a decision within 21 days of the date of hearing, they shall be discharged, and three new arbitrators shall be appointed and shall proceed in the same manner and the process shall be repeated until a decision is reached by at
least two of the three arbitrators selected.

 Each of the officers has executed an

 In addition, IMCO hereby agrees that effective on and as of the Closing, IMCO shall assume
the obligations contained in that certain letter agreement between Commonwealth and John Wasz dated September 7, 2004, a copy of which is attached hereto.
