Stock Option Award Agreement - Chief Executive Officer (Charles P. Blankenship) Initial Equity Award, effective January 19, 2018

The terms and conditions of this Stock Option Award Agreement are authorized by the Compensation and Benefits Committee of the Board of Directors. The Stock Option award is granted to the Participant under the 2013 Arconic Stock Incentive Plan, as amended and restated and as may be further amended from time to time (the “Plan”). Terms that are defined in the Plan have the same meanings in the Award Agreement.

NOTE: To avoid cancellation of the Stock Option, the Participant must affirmatively accept the Stock Option and the terms of this Award Agreement within 6 months of the grant date, as set forth in paragraph 40 of the Award Agreement.

1. The Stock Option award is subject to the terms and conditions set forth in the Participant’s account at Merrill Lynch’s OnLine^® website www.benefits.ml.com, the provisions of the Plan and the Award Agreement. If the Plan and the Award Agreement are inconsistent, the provisions of the Plan will govern. Interpretations of the Plan and the Award Agreement by the Committee are binding on the Participant and the Company.

2. The exercise price (or option price) of the Stock Option is 100% of the fair market value per Share on the date of grant, unless the Participant’s account at Merrill Lynch’s OnLine^® website www.benefits.ml.com, specifies a higher exercise price.

3. The expiration date of a Stock Option is ten years after the date of grant.

4. The Stock Option vests in full on the fourth anniversary of the grant date.

5. Except as provided in paragraph 7, once vested, a Stock Option may be exercised until its expiration date, as long as the Participant remains an active employee of the Company or a Subsidiary. As an administrative matter, the vested portion of this Stock Option may be exercised only until the close of the New York Stock Exchange on the expiration date or such earlier termination date set forth in paragraph 7 or, if such date is not a business day on the New York Stock Exchange, the last business day before such date. Any later attempt to exercise the Stock Option will not be honored. The Participant is solely responsible for any election to exercise the Stock Option, and the Company has no obligation to provide notice to the Participant of any matter, including, but not limited to, the date the Stock Option terminates. Neither the Company nor any Subsidiary has any liability in the event of the Participant’s failure to timely exercise any vested Stock Option prior to its expiration.

6. Except as provided in paragraph 7:

7. The following are exceptions to the vesting and exercisability rules:  

A Participant is deemed to be permanently and totally disabled if the Participant is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months. A Participant shall not be considered to be permanently and totally disabled unless the Participant furnishes proof of the existence thereof in such form and manner, and at such times, as the Company may require. In the event of a dispute, the determination whether a Participant is permanently and totally disabled will be made by the Committee or its delegate.

For purposes of this paragraph, employment by “the entity acquiring the business” includes employment by a subsidiary or affiliate of the entity acquiring the business; and “divestiture of a business” means the sale of assets or stock resulting in the sale of a going concern. “Divestiture of a business” does not include a plant shut down or other termination of a business.

8. A vested, exercisable option is exercised when a signed notification of exercise is received by Merrill Lynch’s OnLine^® website www.benefits.ml.com.

9. Payment in full of the exercise price of a Stock Option is due on the exercise date. Payment of the option exercise price may be made:

10. A Participant may elect to pay the cash exercise price of the option through a “broker-assisted cashless exercise,” using Merrill Lynch’s OnLine^® website www.benefits.ml.com. On or prior to the exercise date, the Participant must deliver the Participant’s instruction directing and obligating the broker to (a) sell Shares (or a sufficient portion of the Shares) acquired upon exercise of the option and (b) remit to the Company a sufficient portion of the sale proceeds to pay the entire exercise price and any tax withholding resulting from the exercise. Such proceeds are due not later than the third trading day after the exercise date.

11. Shares owned by a Participant include (a) those registered in the Participant’s name (or registered jointly with another person), (b) those held in a brokerage account owned by the Participant individually or jointly with another person, and (c) those held in a trust, partnership, limited partnership or other entity for the benefit of the Participant individually (or for the benefit of the Participant jointly with another person). Notwithstanding the foregoing, Shares owned by a Participant do not include Shares held in any qualified plan, IRA or similar tax deferred arrangement or Shares that are otherwise subject to potential accounting limitations regarding their use in stock swap transactions. The Company may require verification or proof of ownership or length of ownership of any shares delivered in payment of the exercise price of an option.

12. All taxes required to be withheld under applicable tax laws in connection with the Stock Option must be paid by the Participant immediately upon exercise (or at the time of any other relevant taxable event).

13. The Company may satisfy applicable tax withholding obligations by any of the means set forth in Section 15(l) of the Plan, except that the Company shall not have discretion to withhold Shares from any Shares deliverable upon exercise for as long the Participant is subject to the short-swing profit rules of Section 16(b) of the Securities Exchange Act of 1934, as amended. Withholding taxes in the United States include applicable income taxes, federal and state unemployment compensation taxes and FICA/FUTA taxes.

14. The amount of taxes that may be paid by a Participant may be determined by applying the minimum rates or, to the extent permitted under applicable accounting principles, up to the maximum individual tax rate for the applicable tax jurisdiction required by applicable tax regulations.

15. The Participant acknowledges that neither the Company nor any Subsidiary has made any representation or given any advice to the Participant with respect to taxes.

16. If permitted by the Company, Participants will be entitled to designate one or more beneficiaries to receive all Stock Options that are unexercised at the time of the Participant’s death. All beneficiary designations will be on a beneficiary designation form approved for the Plan. Copies of the form are available from the Communications Center on Merrill Lynch’s Benefits OnLine^® www.benefits.ml.com.

17. Beneficiary designations on an approved form will be effective at the time received by Merrill Lynch’s OnLine^® website www.benefits.ml.com. A Participant may revoke a beneficiary designation at any time by written notice to Merrill Lynch’s OnLine^® website www.benefits.ml.com or by filing a new designation form. Any designation form previously filed by a Participant will be automatically revoked and superseded by a later-filed form.

18. A Participant will be entitled to designate any number of beneficiaries on the form, and the beneficiaries may be natural or corporate persons.

19. The failure of any Participant to obtain any recommended signature on the form will not prohibit the Company from treating such designation as valid and effective. No beneficiary will acquire any beneficial or other interest in any Stock Option prior to the death of the Participant who designated such beneficiary.

20. Unless the Participant indicates on the form that a named beneficiary is to receive unexercised options only upon the prior death of another named beneficiary, all beneficiaries designated on the form will be entitled and required to join in the exercise of the option. Unless otherwise indicated, all such beneficiaries will have an equal, undivided interest in all such Stock Options.

21. Should a beneficiary die after the Participant but before the option is exercised, such beneficiary’s rights and interest in the option award will be transferable by last will and testament of the beneficiary or the laws of descent and distribution. A named beneficiary who predeceases the Participant will obtain no rights or interest in a stock option award, nor will any person claiming on behalf of such individual. Unless otherwise specifically indicated by the Participant on the beneficiary designation form, beneficiaries designated by class (such as “children,” “grandchildren” etc.) will be deemed to refer to the members of the class living at the time of the Participant’s death, and all members of the class will be deemed to take “per capita.”

22. If a Participant does not designate a beneficiary or if the Company does not permit a beneficiary designation, the Stock Options that are unexercised at the time of death of the Participant will be transferred to the Participant’s legal heirs pursuant to the Participant’s last will and testament or by the laws of descent and distribution and may be exercised by the legal heirs as set forth in paragraph 7.

23. Upon approval of, and subject to such requirements as may be imposed by, the Company, vested Stock Options may be transferred to one or more immediate family members, individually or jointly. A trust, each of whose beneficiaries is the Participant or an immediate family member, will be deemed to be a family member for purposes of these rules.

24. Any permitted transfer of Stock Options shall be effective on the date written notice thereof, on a form approved for this purpose, is received. Copies of the form are available from the Communications Center on Merrill Lynch’s Benefits OnLine^® website www.benefits.ml.com. As a condition to transfer, the Participant shall agree to remain responsible to pay the applicable taxes due in relation to the option. The Participant or the Participant’s estate will be required to provide sufficient evidence of ability to pay such taxes upon the Company’s request.

25. A transfer shall be irrevocable; no subsequent transfer by the transferee shall be effective. Notwithstanding the foregoing, a transferee shall be entitled to designate a beneficiary in accordance with the provisions of paragraphs 16 through 22 above. Except where a beneficiary has been designated, in the event of death of the transferee prior to option exercise, the transferee’s option will be transferable by last will and testament or the laws of descent and distribution.

26. Except as modified by the provisions of paragraphs 23 through 25, all terms applicable to option exercises by Participants are applicable to exercises by transferees. The Plan administrator may make and publish additional rules applicable to exercises by transferees not inconsistent with these provisions.

27. In the event of an Equity Restructuring, the Committee will equitably adjust the Stock Option as it deems appropriate to reflect the Equity Restructuring, which may include (i) adjusting the number and type of securities subject to the Stock Option; and (ii) adjusting the terms and conditions of the Stock Option, including the exercise price. The adjustments provided under this paragraph 27 will be nondiscretionary and final and binding on all interested parties, including the affected Participant and the Company; provided that the Committee will determine whether an adjustment is equitable.

28. Notwithstanding anything to the contrary herein, pursuant to Section 15(e) of the Plan the Committee has full power and authority, to the extent permitted by governing law, to determine that a Stock Option will be canceled or suspended at any time prior to a Change in Control: (i) if the Participant, without the consent of the Committee, while employed by the Company or a Subsidiary or after termination of such employment, becomes associated with, employed by, renders services to or owns any interest (other than an interest of up to 5% in a publicly traded company or any other nonsubstantial interest, as determined by the Committee) in any business that is in competition with the Company or any Subsidiary; (ii) in the event of the Participant’s willful engagement in conduct which is injurious to the Company or any Subsidiary, monetarily or otherwise; (iii) in the event of an Executive Officer’s misconduct described in Section 15(f) of the Plan; or (iv) in order to comply with applicable laws as described in Section 15(h) of the Plan.

Further, as an additional condition of receiving the Stock Option, the Participant agrees that the Stock Option and any benefits or proceeds the Participant may receive hereunder shall be subject to forfeiture and/or repayment to the Company to the extent required (i) under the terms of any recoupment or “clawback” policy adopted by the Company to comply with applicable laws or with the Company’s Corporate Governance Guidelines or other similar requirements, as such policy may be amended from time to time (and such requirements shall be deemed incorporated into the Award Agreement without the Participant’s consent) or (ii) to comply with any requirements imposed under applicable laws and/or the rules and regulations of the securities exchange or inter-dealer quotation system on which the Shares are listed or quoted, including, without limitation, pursuant to Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Further, if the Participant receives any amount in excess of what the Participant should have received under the terms of the Stock Option for any reason (including without limitation by reason of a financial restatement, mistake in calculations or administrative error), all as determined by the Committee, then the Participant shall be required to promptly repay any such excess amount to the Company.

29. Stock Exchange Requirements; Applicable Laws. Notwithstanding anything to the contrary in the Award Agreement, no Shares purchased upon exercise of the Stock Option, and no certificate representing all or any part of such Shares, shall be issued or delivered if, in the opinion of counsel to the Company, such issuance or delivery would cause the Company to be in violation of, or to incur liability under, any securities law, or any rule, regulation or procedure of any U.S. national securities exchange upon which any securities of the Company are listed, or any listing agreement with any such securities exchange, or any other requirement of law or of any administrative or regulatory body having jurisdiction over the Company or a Subsidiary.

30. Shareholder Rights. No person or entity shall be entitled to vote, receive dividends or be deemed for any purpose the holder of any Shares until the Stock Option shall have been duly exercised to purchase such Shares in accordance with the provisions of the Award Agreement.

31. Notices. Any notice required or permitted under the Award Agreement shall be in writing and shall be deemed sufficient when delivered personally or sent by confirmed email, telegram, or fax or five days after being deposited in the mail, as certified or registered mail, with postage prepaid, and addressed to the Company at the Company’s principal corporate offices or to the Participant at the address maintained for the Participant in the Company’s records or, in either case, as subsequently modified by written notice to the other party.

32. Severability and Judicial Modification. If any provision of the Award Agreement is held to be invalid or unenforceable under the applicable laws of any country, state, province, territory or other political subdivision or the Company elects not to enforce such restriction, the remaining provisions shall remain in full force and effect and the invalid or unenforceable provision shall be modified only to the extent necessary to render that provision valid and enforceable to the fullest extent permitted by law. If the invalid or unenforceable provision cannot be, or is not, modified, that provision shall be severed from the Award Agreement and all other provisions shall remain valid and enforceable.

33. Successors. The Award Agreement shall be binding upon and inure to the benefit of the Company and its successors and assigns, on the one hand, and the Participant and his or her heirs, beneficiaries, legatees and personal representatives, on the other hand.

34. Imposition of Other Requirements. The Company reserves the right to impose other requirements on the Participant’s participation in the Plan, on the Stock Option and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require the Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

35. Waiver. A waiver by the Company of breach of any provision of the Award Agreement shall not operate or be construed as a waiver of any other provision of the Award Agreement, or of any subsequent breach by the Participant or any other Participant.

36. No Advice Regarding Award. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Participant’s participation in the Plan, or the Participant’s acquisition or sale of the underlying Shares. The Participant is hereby advised to consult with the Participant’s own personal tax, legal and financial advisors regarding the Participant’s participation in the Plan before taking any action related to the Plan.

37. Governing Law and Venue. As stated in the Plan, the Stock Option and the provisions of the Award Agreement and all determinations made and actions taken thereunder, to the extent not otherwise governed by the laws of the United States, shall be governed by the laws of the State of New York, United States of America, without reference to principles of conflict of laws, and construed accordingly. The jurisdiction and venue for any disputes arising under, or any actions brought to enforce (or otherwise relating to), the Stock Option will be exclusively in the courts in the State of New York, County of New York, including the Federal Courts located therein (should Federal jurisdiction exist).

38. Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

39. Entire Agreement. The Award Agreement and the Plan embody the entire understanding and agreement of the parties with respect to the subject matter hereof, and no promise, condition, representation or warranty, express or implied, not stated or incorporated by reference herein, shall bind either party hereto.

40. As permitted by Section 15(c) of the Plan, receipt of this Award of Stock Options is subject to the Participant’s acceptance of the Stock Option and the terms of this Award Agreement and the Plan through Merrill Lynch’s OnLine^® website www.benefits.ml.com and/or through such other procedures as may be required by the Company (Participant’s “Acceptance”). To avoid forfeiture of the Stock Option award, the Participant must provide such Acceptance within 6 months of the grant date of the Stock Option. The date as of which the Participant’s Stock Option shall be forfeited, if the Participant has not provided such Acceptance, will generally be set forth in the Participant’s account at Merrill Lynch’s OnLine^® website. If the Participant does not provide Acceptance within this 6 month period, the Award of Stock Options will be cancelled in accordance with any administrative procedures adopted under the Plan.
