Lawson ("Consultant").

WHEREAS, Elliott desires to retain Consultant to perform certain consulting, advisory and other services more specifically described below for Elliott, and Consultant desires to perform such services for Elliott upon the terms and conditions hereinafter set forth.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

Section. 1. Retention of Consultant. Elliott hereby retains Consultant as an advisor and consultant to Elliott and Consultant hereby accepts such retention by Elliott, upon the terms and subject to the conditions of this Agreement.

Section. 2. Services. During the Term (as hereinafter defined), Consultant shall provide to Elliott general advisory and professional consulting services (the "Services"), including, but not limited to, in connection with Elliott's nomination of individuals for election to the board of directors of Arconic Inc., a Pennsylvania corporation ("Arconic"), at the 2017 annual meeting of shareholders of Arconic. The duties required of Consultant will be consistent in level with a person of Consultant's background and experience. During the Term, Consultant will report directly to Jonathan Pollock.

Section. 3. Fees. For performance of the Services, Elliott shall pay Consultant

(a) a consulting fee of $100,000 per calendar month (the "Fee"), payable on the first day of each calendar month during the Term, commencing February 1, 2017;

(b) a supplemental fee of $1,000,000 (the "Supplemental Fee"), payable in a lump sum on the date hereof; and

(c) an additional fee of $3,000,000 (the "Additional Fee"), payable on August 1, 2017 in the event that Consultant is not the chief executive officer of Arconic on or prior to July 31, 2017.

(d) If on or prior to July 31, 2017, Consultant is the chief executive officer of Arconic, Consultant shall, within fifteen days of becoming the chief executive officer of Arconic, use an amount equal to the net after-tax proceeds to Consultant from the Supplemental Fee to purchase common stock of Arconic on the public market, subject to any applicable trading restrictions imposed by Arconic, in which case Consultant shall use such funds to purchase Arconic common stock within the first fifteen days of trading permitted under applicable Arconic trading restrictions.

Section. 4. Nature and Relationship.

(a) Consultant undertakes and shall be responsible to perform the Services as specifically set forth in this Agreement, and no implied covenants or obligations shall be read into this Agreement or be enforceable against Consultant. Consultant shall perform the Services diligently and in a professional and workmanlike manner to meet the results and accomplish the tasks reasonably requested by Elliott. Consultant agrees to devote the amount of time in performance of the Services as may reasonably be agreed between Consultant and Elliott, provided that the foregoing shall not impair Consultant from performing any services pursuant to the Retirement and Consulting Agreement and General Release, dated June 7, 2016 between Spirit Aerosystems Inc. and Consultant.

Nothing contained herein shall be construed as creating, or be deemed to create, the relationship of employer and employee between the parties, nor any agency. Consultant shall perform all Services under this Agreement as an independent contractor, and nothing contained in this Agreement shall be deemed to create any association, partnership, joint venture, or relationship of principal and agent or master and servant between the parties to this Agreement or any affiliates or subsidiaries thereof.

(d) Consultant shall not have any authority nor responsibility for the management of Elliott, and shall be responsible only for such tasks as are specifically and reasonably assigned to Consultant.

Section. 5. Business Expenses. Elliott shall reimburse Consultant, for all reasonable and necessary, documented out-of-pocket expenses incurred by Consultant directly related to Consultant's performance of the Services, including, without limitation, reimbursement for reasonable travel expenses (at least business-class) and legal fees (any such expenses, "Reimbursable Expenses"). Any Reimbursable Expense (or series of related Reimbursable Expenses) to be incurred by Consultant in an amount over $25,000 must be pre-approved in writing by Elliott, which approval will not be unreasonably withheld, conditioned or delayed.

Section. 6. Taxes. Consultant shall duly and timely comply with all applicable laws relating to the collection or withholding and reporting and remittance of any and all federal, state or local taxes, charges or fees (the "Taxes") resulting from the receipt of the Fee hereunder and any other benefits provided to him by Elliott.

Section. 12. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to principles of conflicts of laws.

Section. 13. Code Section 409A. It is the intent of the parties that this Agreement not violate any applicable provision of, or result in any additional tax, interest or penalty under, Section 409A of the Internal Revenue Code ("Section 409A"), and that to the extent any provisions of this Agreement do not comply with or are not exempt from Section 409A, the parties will make such changes as are mutually agreed upon in order to comply with or obtain an exemption from Section 409A. Any reimbursement to Consultant pursuant to this Agreement will be made reasonably promptly following Consultant's submission of a request for reimbursement and in any event not later than the last day of the calendar year after the calendar year in which the expenses are incurred, and any reimbursement in a taxable year of Consultant will not affect any reimbursement in another taxable year of Consultant nor be subject to liquidation or exchange for another benefit. Any series of payments will be considered separate payments for the purposes of Section 409A. For purposes of any provision of this Agreement providing for the payment of any amounts or benefits that constitute nonqualified deferred compensation under Section 409A upon or following a termination of services or the end of the Term, no such event will be deemed to have occurred unless such termination or end of the Consulting Period is also a "separation from service" within the meaning of Section 409A. Any payment or reimbursement for taxes shall be paid to Consultant promptly after such obligation is incurred, but in no event later than the end of the calendar year next following the calendar year in which the tax is paid by Consultant. In addition, in the event Consultant incurs expenses due to a tax audit or litigation addressing the existence or amount of a tax liability covered under the indemnity provisions of the Indemnification Agreement, Elliott shall promptly reimburse Consultant after such amounts are incurred, but in no event later than end of the calendar year next following the calendar year in which the taxes that are subject to the audit or investigation are remitted by Consultant to the taxing authority, or if, as a result of such audit or investigation no taxes are remitted, not later than the end of the calendar year following the calendar year in which the audit is completed or there is a final and nonappealable settlement or other resolution of the litigation.

Section. 14. Waiver of Breach. Any term or condition of this Agreement may be waived at any time by the party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the party waiving such term or condition. No waiver by any party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion.

Section. 15. Entire Agreement; Amendments. This Agreement and the Indemnification Agreement contain the entire agreement between the parties with respect to the subject matter hereof and supersede all prior agreements or understandings between the parties with respect thereto.

(a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the United States District Court for the Southern District of New York, or if such court lacks jurisdiction, the Supreme Court of the State of New York in New York County, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement.
