The Executive has announced his decision to retire from the Company as Chairman and Chief Executive Officer and Chairman, President and Chief Executive Officer of the Forged and Cast Engineered Products Group effective April 30, 2016 (the “Retirement Date”). Following the Retirement Date, the Company wishes to retain the Executive for the purpose of providing, and the Executive has agreed to provide, certain consulting services. This Agreement is intended to set forth the terms applicable to the Executive’s retirement from the Company and the consulting arrangement following the Retirement Date.

NOW, THEREFORE, the parties, intending to be legally bound, agree as follows:

1. Resignation and Retirement . Effective on the Retirement Date, the Executive will resign from all positions with the Company and any subsidiaries of the Company then held by him, except for his position as a director of each of Gongchang Roll Co., Ltd and Union Electric Steel MG Roll Co., Ltd (a/k/a “Masteel Gongchang Roll Company”)) and the Executive’s employment with the Company will terminate due to his retirement.

2. Consulting Services .

Beginning on May 1, 2016 and ending on May 31, 2017 (such period, subject to the extension and early termination provisions of Section 2(d) below, the “Consulting Period”), the Executive agrees to cooperate with the Company in the transition of management of the Company following Executive’s retirement and to provide such consulting services to the Company (the “Consulting Services”) as may be requested by the President of the Company or the Chief Executive Officer of Ampco-Pittsburgh Corporation and be agreed to by the Executive, which agreement may not be unreasonably withheld by Executive. The Executive agrees to provide up to five (5) days of Consulting Services to the Company per month during the Consulting Period with the exception of the entire months of February and March, 2017.

representative or affiliate, either for itself or as a member of a partnership or as a stockholder, investor, officer or director of a corporation or as an employee, agent, associate, adviser or consultant to or of any person, partnership, corporation or other entity, any business that is competitive with a business that the Company or any other subsidiary of Ampco-Pittsburgh Corporation is engaged in as of the Retirement Date;  provided  that nothing in this provision shall restrict the Executive from the Executive’s passive ownership of up to 2% of a publicly traded stock in one or more public companies engaged in a competing business.
