For service as member of the compensation committee other than as its Chair: an annual cash retainer of $5,000 (in addition to any annual cash retainers otherwise paid).

Payment of Retainers. The retainers described in Sections I(A) and (B) shall be earned on a quarterly basis based on a calendar quarter and shall be paid in cash by the Company in arrears not later than the fifteenth day following the end of each calendar quarter. In the event a Non-Employee Director does not serve as a Non-Employee Director, or in the applicable positions described in Section I(B), for an entire calendar quarter, the retainer paid to such Non-Employee Director shall be prorated for the portion of such calendar quarter actually served as a Non-Employee Director, or in such position, as applicable.

Deferral of Retainers. Non-Employee Directors may elect to defer payment of all or a portion of the annual retainers described in Section 2(a) and the exceptional meeting fees described in Section 2(d) into specified investment funds and/or into vested restricted share units for shares of the Company's common stock, which deferral will be made pursuant to the terms of the Company's Amended and Restated Deferred Fee Plan for Directors or its successor plan (the "Deferred Fee Plan"). Unless otherwise determined by the Board, any restricted share units will be granted under the 2013 Howmet Aerospace Stock Incentive Plan or its successor plan (the "Equity Plan"), on the date on which such retainer(s) would otherwise have been paid in cash. The extent to which a Non-Employee Director may defer annual retainer payments into vested restricted share units will therefore be subject to any limit on awards granted to a Non-Employee Director set forth in the Equity Plan.

Deferral of Retainers. A Participant’s election to defer a Retainer is subject to the following requirements:

Annual Bonus. In addition to Base Salary, the Executive will be eligible to earn a Bonus for each fiscal year ending during the Protected Period. For each such Bonus, the Target Opportunity will be at least equal to the target opportunity for which the Executive is eligible for the fiscal year in which the Change in Control occurs, as such target opportunity has been established by the Company for such year under the Company’s annual bonus plan, or any comparable successor plan. If the Company has not yet established a Target Opportunity for the Executive for the fiscal year in which the Change in Control occurs, then the Target Opportunity shall be at least equal to the last such target opportunity established by the Company for the Executive. Each such Bonus will be paid no later than 2-1/2 months following the end of the fiscal year for which the Bonus is awarded, unless the Executive has elected to defer receipt of all or part of the Bonus pursuant to a deferral plan sponsored by the Company.
