shall be deemed to be issued hereunder only when and to the extent that payment or settlement of an Award is actually made in Shares. Notwithstanding anything herein to the contrary, the Committee may at any time authorize a cash payment in lieu of
Shares, including without limitation if there are insufficient Shares available for issuance under the Plan to satisfy an obligation created under the Plan. 

(d) Source of Shares. Any Shares issued hereunder may consist, in whole or in part, of authorized and unissued Shares, treasury Shares or Shares
purchased in the open market or otherwise. 
 (e) Substitute Awards. Shares issued or granted in connection with Substitute Awards shall not reduce

of shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other change affecting the Shares or the price of the Shares other than an Equity Restructuring, the Committee shall
make such adjustments, if any, as the Committee in its discretion may deem appropriate to reflect such change with respect to (i) the aggregate number and kind of shares that may be issued under the Plan (including, but not limited to,
adjustments of the limitations in Sections 4(a) and 13(f) hereof); (ii) the terms and conditions of any outstanding Awards (including, without limitation, any applicable performance targets or criteria with respect thereto); and (c) the
grant or exercise price per Share for any outstanding Awards under the Plan. Any adjustment affecting an Award intended to be “performance-based compensation” within the meaning of Section 162(m)(4)(C) of the Code, or any successor

 In the event of any transaction or event described above in this Section 4(f)(i) or any
unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate, or of changes in applicable laws, regulations or accounting principles, the Committee,
on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change in applicable laws or accounting principles
may be made within a reasonable period of time after such change), is hereby authorized to take actions, including but not limited to any one or more of the following actions, whenever the Committee determines that such action is appropriate in
order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any Award under the Plan, to facilitate such transactions or events or to give effect to such changes in
laws, regulations or principles, provided that the number of Shares subject to any Award will always be a whole number: 
  

	 	(A)	To provide for either (I) termination of any such Award in exchange for an amount of cash, if any, equal to the amount that would have been attained upon the exercise of such Award or realization of the
Participant’s rights (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction or event described above in this Section 4(f)(i) the Committee determines in good faith that no amount would have been attained
upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment) or (II) the replacement of such Award with other rights or property selected by the Committee in its
sole discretion; 

  

	 	(B)	To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar options, rights or awards covering the stock of the successor or
survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices; 

  

	 	(C)	To make adjustments in the number and type of Shares (or other securities or property) subject to outstanding Awards, and in the number and kind of outstanding Restricted Shares and/or in the terms and conditions of
(including the grant or exercise price), and the criteria included in, outstanding options, rights and awards; 

  

	 	(D)	To provide that such Award shall be exercisable or payable or fully vested with respect to all Shares covered thereby; or 

  

	 	(E)	To provide that the Award cannot vest, be exercised or become payable after such event. 

 (ii)
Equity Restructuring. In connection with the occurrence of any Equity Restructuring, and notwithstanding anything to the contrary in this Section 4(f), the Committee will adjust the terms of the Plan and each outstanding Award as it
deems equitable to reflect the Equity Restructuring, which may include (i) adjusting the number and type of securities subject to each outstanding Award and/or with respect to which Awards may be granted under the Plan (including, but not
limited to, adjustments of the limitations in Sections 4(a) and 13(f) hereof); (ii) adjusting the terms and conditions of (including the grant or exercise price), and the performance targets or other criteria included in, outstanding Awards;
and (iii) granting new Awards or making cash payments to Participants. The adjustments provided under this Section 4(f)(ii) 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 and the number of Shares subject to any Award will always be a whole number.

 (c) Exercisability. Options
shall be exercisable at such time or times as determined by the Committee at or subsequent to grant, provided, however, that the minimum vesting period of an Option shall be one year except in connection with an adjustment provided for in
Section 4(f), Substitute Awards or Converted Awards. 
 (d) Method of Exercise. Subject to the other provisions of the Plan, any Option may be
exercised by the Participant in whole or in part at such time or times, and the Participant may make payment of the Option price in such form or forms, including, without limitation, payment by delivery of cash, Shares or other consideration
(including, where permitted by law and the Committee, Awards) having a fair market value on the exercise date equal to the total Option price, or by any combination of cash, Shares and other consideration as the Committee may specify in the
applicable Award Agreement. 
 SECTION 7. STOCK APPRECIATION RIGHTS. Stock Appreciation Rights may be granted to Participants on such terms and
conditions as the Committee may determine, subject to the requirements of the Plan. A Stock Appreciation Right shall confer on the holder a right to receive, upon exercise, the excess of (i) the Fair Market Value of one Share on the date of
exercise or, if the Committee shall so determine, at any time during a specified period before the date of exercise over (ii) the grant price of the right on the date of grant, or if granted in connection with an outstanding Option on the date
of grant of the related Option, as specified by the Committee in its sole discretion, which, except in the case of Substitute Awards, Converted Awards or in connection with an adjustment provided in Section 4(f), shall not be less than the Fair
Market Value of one Share on such date of grant of the right or the related Option, as the case may be. Any payment by the Company in respect of such right may be made in cash, Shares, other property or any combination thereof, as the Committee, in
its sole discretion, shall determine. The Committee may, in its sole discretion, establish a limit on the amount of gain that can be realized on a Stock Appreciation Right. 

(a) Grant Price. The grant price for a Stock Appreciation Right shall be determined by the Committee, provided, however, and except as provided in
Section 4(f) and for Substitute Awards and Converted Awards, that such price shall not be less than 100% of the Fair Market Value of one Share on the date of grant of the Stock Appreciation Right. 

(b) Term. The term of each Stock Appreciation Right shall not exceed ten years from the date of grant, or if granted in tandem with an Option, the
expiration date of the Option. The minimum vesting period of a Stock Appreciation Right shall be one year, except in connection with an adjustment provided for in Section 4(f), Substitute Awards or Converted Awards. 

(c) Time and Method of Exercise. The Committee shall establish the time or times at which a Stock Appreciation Right may be exercised in whole or in
part.

discretion, may impose (including, without limitation, any contingency or restriction on the right to vote such Share and the right to receive any cash dividends), which contingencies and restrictions may lapse separately or in combination, at such
time or times, in installments or otherwise, as the Committee may deem appropriate.

 (b) Issuance. A Restricted Share Award shall be subject to contingencies or restrictions imposed by the
Committee during a period of time specified by the Committee (the “Contingency Period”). Restricted Share Awards may be issued hereunder to Participants, for no cash consideration or for such minimum consideration as may be required by

the name of the Participant and shall bear an appropriate legend referring to the terms, conditions, contingencies and restrictions applicable to such Award. 

(d) Forfeiture. Except as otherwise determined by the Committee at the time of grant or thereafter or as otherwise set forth in the terms and
conditions of an Award, upon termination of service for any reason during the Contingency Period, all Restricted Shares still subject to any contingency or restriction shall be forfeited by the Participant and reacquired by the Company. 

(e) Minimum Restrictions. Restricted Share Awards that are restricted only on the passage of time shall have a minimum three-year pro-rata restriction
period (the restrictions lapse each year as to 1/3 of the Restricted Share Awards), except in connection with an adjustment provided for in Section 4(f), Substitute Awards or Converted Awards; provided, however, that a restriction period of
less than this period may be approved for Awards with respect to up to 5% of the Shares authorized under the Plan.

Restricted Share Unit Awards may be issued for no cash consideration or for such minimum consideration as may be required by applicable law. Shares (including securities convertible into Shares) purchased pursuant to a purchase right granted under
this SECTION 9 thereafter shall be purchased for such consideration as the Committee shall in its sole discretion determine, which shall not be less than the Fair Market Value of such Shares or other securities as of the date such purchase right is
granted.

Awards may be paid in cash, Shares, other property or any combination thereof in the sole discretion of the Committee. The performance levels to be achieved for each Performance Period and the amount of the Award to be paid shall be conclusively
determined by the Committee. Except as provided in SECTION 12, each Performance Award shall be paid following the end of the Performance Period or, if later, the date on which any applicable contingency or restriction has ended.

Change in Control: 
 (i) any Time-Based Award consisting of Options, Stock Appreciation Rights or any other Time-Based Award in the form of
rights that are exercisable by Participants upon vesting (“Exercisable Time-Based Award”), that is outstanding as of the date on which a Change in Control shall be deemed to have occurred and that is not then vested, shall become vested
and exercisable, unless replaced by a Replacement Award; 
 (ii) any Time-Based Award that is not an Exercisable Time-Based Award that is
outstanding as of the date on which a Change in Control shall be deemed to have occurred and that is not then vested, shall become free of all contingencies, restrictions and limitations and shall become vested and transferable, unless replaced by a
Replacement Award; 
 (iii) any Replacement Award for which an Exercisable Time-Based Award has been exchanged upon a Change in Control shall
vest and become exercisable in accordance with the vesting schedule and term for exercisability that applied to the corresponding Exercisable Time-Based Award immediately prior to such Change in Control, provided, however, that if
within twenty four (24) months of such Change in Control, the Participant’s service with the Company or a Subsidiary is terminated without Cause (as such term is defined in the Alcoa Corporation Change in Control Severance Plan) or by the
Participant for Good Reason (as such term is defined in the Alcoa Corporation Change in Control Severance Plan), such Award shall become vested and exercisable to the extent outstanding at the time of such termination of service. Any Replacement
Award that has become vested and exercisable pursuant to this paragraph shall expire on the earlier of (A) thirty six (36) months following the date of termination of such Participant’s service (or, if later, the conclusion of the
applicable post-termination exercise period pursuant to the applicable Award Agreement) and (B) the last day of the term of such Replacement Award; 

(iv) any Replacement Award for which a Time-Based Award that is not an Exercisable Time-Based Award has been exchanged upon a Change in Control

Control, the Participant’s service with the Company or a Subsidiary is terminated without Cause (as such term is defined in the Alcoa Corporation Change in Control Severance Plan) or by the Participant for Good Reason (as such term is defined
in the Alcoa Corporation Change in Control Severance Plan), such Award shall become free of all contingencies, restrictions and limitations and become vested and transferable to the extent outstanding; 

(v) any Performance Award shall be converted so that such Award is no longer subject to any performance condition referred to in SECTION 11
above, but instead is subject to the passage of time, with the number or value of such Replacement Award determined as follows: (A) if 50% or more of the Performance Period has been completed as of the date on which such Change in Control is
deemed to have occurred, the number or value of such Award shall be based on actual performance during the Performance Period; or (B) if less than 50% of the Performance Period has been completed as of the date on which such Change in Control
is deemed to have occurred, the number or value of such Award shall be the target number or value. Paragraphs (i) through (iv) above shall govern the terms of such Time-Based Award.

 (b) Change in Control Settlement. Notwithstanding any other provision of this Plan, if approved by the
Committee, upon a Change in Control, a Participant may receive a cash settlement under clauses (i) and (ii) below of existing Awards that are vested and exercisable as of the date on which such Change in Control shall be deemed to have
occurred: 
 (i) a Participant who holds an Option or Stock Appreciation Right may, in lieu of the payment of the purchase price for the
Shares being purchased under the Option or Stock Appreciation Right, surrender the Option or Stock Appreciation Right to the Company and receive cash, within 30 days of the Change in Control, in an amount equal to the amount by which the Fair Market
Value of the Shares on the date of the Change in Control exceeds the purchase price per Share under the Option or Stock Appreciation Right multiplied by the number of Shares granted under the Option or Stock Appreciation Right; and 

(ii) a Participant who holds Restricted Share Units may, in lieu of receiving Shares which have vested under Section 12(a)(ii) of this
Plan, receive cash, within 30 days of a Change in Control, in an amount equal to the Fair Market Value of the Shares on the date of the Change in Control multiplied by the number of Restricted Share Units held by the Participant. 

SECTION 13. CODE SECTION 162(m) PROVISIONS. 
 (a)
Notwithstanding any other provision of this Plan, if the Committee determines at the time a Restricted Share Award, a Performance Award or a Restricted Share Unit Award is granted to a Participant that such Participant is, or is likely to be as of
the end of the tax year in which the Company would claim a tax deduction in connection with such Award, a Covered Employee, then the Committee may provide that this SECTION 13 is applicable to such Award. 

(b) If an Award is subject to this SECTION 13, then the lapsing of contingencies or restrictions thereon and the distribution of cash, Shares or other
property pursuant thereto, as applicable, shall be subject to the achievement by the Company on a consolidated basis, and/or by specified Subsidiaries or divisions or business units of the Company, as appropriate, of one or more objective
performance goals established by the Committee. Performance goals shall be set by the Committee (and any adjustments shall be made by the Committee) within the time period prescribed by, and shall otherwise comply with, the requirements of
Section 162(m) of the Code, or any successor provision thereto, and the regulations thereunder. 
 (c) As the Committee deems appropriate, performance
goals established by the Committee may be based upon (x) the achievement of specified levels of Company, Subsidiary, division or business unit performance under one or more of the measures described below, (y) the improvement in Company,
Subsidiary, division or business unit performance under one or more of the measures, and (z) Company, Subsidiary or business unit performance under one or more of the measures relative to the performance of other comparator companies or groups
of companies or an external index or indicator. Performance goals may include a threshold level of performance below which no Award will be earned, levels of performance at which an Award will become partially earned, and a level of performance at
which an Award will be fully earned. Any of the measures listed below, as applicable, may be calculated to exclude special items, unusual or infrequently occurring items or nonrecurring items or may be normalized for fluctuations in market forces,
including, but not limited to, foreign currency exchange rates and the price of aluminum on the London Metal Exchange: 
 (i) earnings,
including earnings margin, operating income, earnings before or after taxes, and earnings before or after interest, taxes, depreciation, and amortization;

debt, capital structure of the Company including debt to capital ratios; 
 (xiii) implementation or completion of critical projects or
processes; 
 (xiv) economic profit, economic value added or created; 

(xv) cumulative earnings per share growth; 

(xvi) achievement of cost reduction goals;

(xxiii) strategic business criteria, consisting of one or more objectives based on market penetration, geographic business expansion, customer
satisfaction (including product quality and delivery), employee satisfaction, human resources management (including diversity representation), supervision of litigation, information technology, and goals relating to acquisitions, divestitures, joint
ventures and similar transactions, and budget comparisons; 
 (xxiv) personal professional objectives, including any of the foregoing
performance measures, the implementation of policies and plans, the negotiation of transactions, the development of long-term business goals, formation of joint ventures, research or development collaborations, technology and best practice sharing
within the Company, and the completion of other corporate goals or transactions; 
 (xxv) sustainability measures, community engagement
measures or environmental, health or safety goals of the Company or the Subsidiary or business unit of the Company for or within which the Participant is primarily employed; or 

(xxvi) audit and compliance measures. 
 (d)
Notwithstanding any provision of this Plan other than Section 4(f) and SECTION 12, with respect to any Award that is subject to this SECTION 13, the Committee may adjust downwards, but not upwards, the amount payable pursuant to such Award, and
the Committee may not waive the achievement of the applicable performance goals. 
 (e) The Committee shall have the power to impose such other restrictions
on Awards subject to this SECTION 13 as it may deem necessary or appropriate to ensure that such Awards satisfy all requirements for “performance-based compensation” within the meaning of Section 162(m)(4)(C) of the Code, or any
successor provision thereto. 
 (f) For purposes of complying with Code Section 162(m) limitations on “performance-based compensation,” and
subject to the adjustment provisions of Section 4(f), no Participant may be granted Options and/or Stock Appreciation Rights in any calendar year with respect to more than 10,000,000 Shares, or Restricted Share Awards or Restricted Share Unit
Awards covering more than 4,000,000 Shares. The maximum dollar value payable with respect to Performance Awards that are valued with reference to property other than Shares and granted to any Participant in any one calendar year is $15,000,000.
Notwithstanding the foregoing, the number of Shares subject to Converted Awards shall be disregarded for purposes of the limitations set forth in this Section 13(f).

 SECTION 14. AMENDMENTS AND TERMINATION. The Board may amend, alter, suspend, discontinue or terminate the
Plan or any portion thereof at any time; provided that notwithstanding any other provision in this Plan, no such amendment, alteration, suspension, discontinuation or termination shall be made: (a) without stockholder approval, if such
approval would be required pursuant to applicable law or the requirements of the New York Stock Exchange or such other stock exchange on which the Shares trade; or (b) without the consent of the affected Participant, if such action would impair
the rights of such Participant under any outstanding Award, except as provided in Sections 15(e) and 15(f). Notwithstanding anything to the contrary herein, the Committee may amend the Plan in such manner as may be necessary so as to have the Plan
conform to local rules and regulations in any jurisdiction outside the United States or to qualify for or comply with any tax or regulatory requirement for which or with which the Board or Committee deems it necessary or desirable to qualify or
comply. 
 SECTION 15. GENERAL PROVISIONS. 
 (a)
Transferability of Awards. Awards may be transferred by will or the laws of descent and distribution. Except as set forth herein, awards shall be exercisable, during the Participant’s lifetime, only by the Participant or, if permissible
under applicable law, by the Participant’s guardian or legal representative. Unless otherwise provided by the Committee or limited by applicable laws, a Participant may, in the manner established by the Committee, designate a beneficiary to
exercise the rights of the Participant with respect to any Award upon the death of the Participant. Unless otherwise provided by the Committee or limited by applicable laws, Awards may be transferred to one or more Family Members, individually or
jointly, or to a trust whose beneficiaries include the Participant or one or more Family Members under terms and conditions established by the Committee. The Committee shall have authority to determine, at the time of grant, any other rights or
restrictions applicable to the transfer of Awards; provided however, that no Award may be transferred to a third party for value or consideration. Except as provided in this Plan or the terms and conditions established for an Award, any Award
shall be null and void and without effect upon any attempted assignment or transfer, including, without limitation, any purported assignment, whether voluntary or by operation of law, pledge, hypothecation or other disposition, attachment, divorce
or trustee process or similar process, whether legal or equitable. 
 (b) Award Entitlement. No Employee or Director shall have any claim to be
granted any Award under the Plan and there is no obligation for uniformity of treatment of Employees or Directors under the Plan. 
 (c) Terms and
Conditions of Award. The prospective recipient of any Award under the Plan shall be deemed to have become a Participant subject to all the applicable terms and conditions of the Award upon the grant of the Award to the prospective recipient,
unless the prospective recipient notifies the Company within 30 days of the grant that the prospective recipient does not accept the Award. This Section 15(c) is without prejudice to the Company’s right to require a Participant to
affirmatively accept the terms and conditions of an Award. 
 (d) Award Adjustments. Except as provided in SECTION 13, the Committee shall be
authorized to make adjustments in Performance Award criteria or in the terms and conditions of other Awards in recognition of unusual or nonrecurring events affecting the Company or its financial statements or changes in applicable laws, regulations
or accounting principles. The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan or any Award in the manner and to the extent it shall deem desirable to carry it into effect. 

(e) Committee Right to Cancel. The Committee shall have full power and authority to determine whether, to what extent and under what circumstances any
Award shall be canceled or suspended at any time prior to a Change in Control: (i) if an Employee, without the consent of the Committee, while employed by the Company or a Subsidiary or after termination of such employment, becomes associated
with, 

  
 11 








 
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); or (iv) in order to comply with applicable laws as described in Section 15(h) below. For purposes of clause (ii), no act, or failure to act, on the
Participant’s part shall be deemed “willful” unless done, or omitted to be done, by the Participant not in good faith and without reasonable belief that the Participant’s act, or failure to act, was in the best interest of the
Company or a Subsidiary. In the event of a dispute concerning the application of this Section 15(e), no claim by the Company shall be given effect unless the Board determines that there is clear and convincing evidence that the Committee has
the right to cancel an Award or Awards hereunder, and the Board finding to that effect is adopted by the affirmative vote of not less than three quarters of the entire membership of the Board (after reasonable notice to the Participant and an
opportunity for the Participant to provide information to the Board in such manner as the Board, in its sole discretion, deems to be appropriate under the circumstances). 

(f) Clawback. Notwithstanding any other provision of the Plan to the contrary, in accordance with the Company’s Corporate Governance Guidelines,
if the Board learns of any misconduct by an Executive Officer that contributed to the Company having to restate all or a portion of its financial statements, the Board will, to the full extent permitted by governing law, in all appropriate cases,
effect the cancellation and recovery of Awards (or the value of Awards) previously granted to the Executive Officer if: (i) the amount of the Award was calculated based upon the achievement of certain financial results that were subsequently
the subject of a restatement, (ii) the executive engaged in intentional misconduct that caused or partially caused the need for the restatement, and (iii) the amount of the Award had the financial results been properly reported would have
been lower than the amount actually awarded. Furthermore, all Awards (including Awards that have vested in accordance with the Award Agreement) shall be subject to the terms and conditions, if applicable, of any other recoupment policy adopted by
the Company from time to time or any recoupment requirement imposed under applicable laws, rules, regulations or stock exchange listing standards, including, without limitation, recoupment requirements imposed pursuant to Section 954 of the
Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, Section 304 of the Sarbanes-Oxley Act of 2002, or any regulations promulgated thereunder, or recoupment requirements under the laws of any other jurisdiction. 

(g) Stock Certificate Legends. All certificates for Shares delivered under the Plan pursuant to any Award shall be subject to such stock transfer
orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of the U.S. Securities and Exchange Commission, any stock exchange upon which the Shares are then listed and any applicable
Federal or state securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 

(h) Compliance with Securities Laws and Other Requirements. No Award granted hereunder shall be construed as an offer to sell securities of the
Company, and no such offer shall be outstanding, unless and until the Company in its sole discretion has determined that any such offer, if made, would be in compliance with all applicable requirements of the U.S. Federal securities laws and any
other laws, rules, regulations, stock exchange listing or other requirements to which such offer, if made, would be subject. Without limiting the foregoing, the Company shall have no obligation to issue or deliver Shares pursuant to Awards granted
hereunder prior to: (i) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable, and (ii) completion of any registration or other qualification with respect to the Shares under any
applicable law in the United States or in a jurisdiction outside of the United States or procurement of any ruling or determination of any governmental body that the Company determines to be necessary or advisable or at a time when any such
registration, qualification or determination is not current, has been suspended or otherwise has ceased to be effective. The inability or impracticability of the Company to obtain or maintain authority from any regulatory body having jurisdiction,
which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such
requisite authority shall not have been obtained, and shall constitute circumstances in which the Committee may determine to amend or cancel Awards pertaining to such Shares, with or without consideration to the affected Participants. 

  
 12 








 (i) Dividends. No Award of Options or Stock Appreciation Rights shall have the right to receive dividends
or dividend equivalents. To the extent that the Board, in its discretion, declares a dividend on the Shares: (i) a recipient of an Award of Restricted Shares shall receive dividends on the Restricted Shares subject to such contingencies or
restrictions, if any, as the Committee, in its sole discretion, may impose; and (ii) dividend equivalents shall accrue on Restricted Share Units (including Restricted Share Units that have a performance feature) and shall only be paid if and when
such Restricted Share Units vest, unless otherwise determined by the Committee. Any dividend equivalents that accrue on Restricted Share Units will be calculated at the same rate as dividends paid on the common stock of the Company. Notwithstanding
any provision herein to the contrary, no dividends or dividend equivalents shall be paid on Restricted Share Units that have not vested or on Restricted Share Units that have not been earned during a Performance Period. 

(j) Consideration for Awards. Except as otherwise required in any applicable Award Agreement or by the terms of the Plan, recipients of Awards under
the Plan shall not be required to make any payment or provide consideration other than the rendering of services. 
 (k) Delegation of Authority by
Committee. The Committee may delegate to one or more Executive Officers or a committee of Executive Officers the right to grant Awards to Employees who are not Executive Officers or Directors of the Company and to cancel or suspend Awards to
Employees who are not Executive Officers or Directors of the Company. 
 (l) Tax Obligations. The Company shall be authorized to withhold from any
Award granted or payment due under the Plan the amount of Tax Obligations due in respect of an Award or payment hereunder and to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the payment of
such Tax Obligations, including without limitation requiring the Participant to pay cash, withholding otherwise deliverable cash or Shares having a fair market value equal to the amount required to be withheld, forcing the sale of Shares issued
pursuant to an Award (or exercise or vesting thereof) having a fair market value equal to the amount required to be withheld, or requiring the Participant to deliver to the Company already-owned Shares having a fair market value equal to the
amount required to be withheld. For purposes of the foregoing, “Tax Obligations” means tax, social insurance and social security liability obligations and requirements in connection with the Awards, including, without limitation,
(i) all U.S. Federal, state, and local income, employment and any other taxes (including the Participant’s U.S. Federal Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company (or a Subsidiary, as
applicable), (ii) the Participant’s and, to the extent required by the Company (or a Subsidiary, as applicable), the Company’s (or a Subsidiary’s) fringe benefit tax liability, if any, associated with the grant, vesting, or
exercise of an Award or sale of Shares issued under the Award, and (iii) any other taxes, social insurance, social security liabilities or premium for which the Participant has an obligation, or which the Participant has agreed to bear, with
respect to such Award (or exercise thereof or issuance of Shares or other consideration thereunder). Furthermore, the Committee shall be authorized to, but is not required to, establish procedures for election by Participants to satisfy such
obligations for the payment of such taxes by delivery of or transfer of Shares to the Company or by directing the Company to retain Shares otherwise deliverable in connection with the Award. All personal taxes applicable to any Award under the Plan
are the sole liability of the Participant. 
 (m) Other Compensatory Arrangements. Nothing contained in this Plan shall prevent the Board from
adopting other or additional compensation arrangements, subject to stockholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases. 

(n) Governing Law. The Plan 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 Delaware, United States of America, without reference to principles of conflict of laws, and construed accordingly. 

(o) Severability. If any provision of this Plan is or becomes or is deemed invalid, illegal or unenforceable in any jurisdiction, or would disqualify
the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to applicable laws or if it cannot be construed or deemed amended without, in the determination of the Committee,
materially altering the intent of the Plan, it shall be stricken and the remainder of the Plan shall remain in full force and effect. 

  
 13 








 (p) Awards to Non-U.S. Employees. Awards may be granted to Employees and Directors who are foreign
nationals or residents or employed outside the United States, or both, on such terms and conditions different from those applicable to Awards to Employees and Directors who are not foreign nationals or residents or who are employed in the United
States as may, in the judgment of the Committee, be necessary or desirable in order to recognize differences in local law, regulations or tax policy. Without limiting the generality of the foregoing, the Committee or the Board, as applicable, are
specifically authorized to (i) adopt rules and procedures regarding the conversion of local currency, withholding procedures and handling of stock certificates which vary with local requirements and (ii) adopt sub-plans, Award Agreements
and Plan and Award Agreement addenda as may be deemed desirable to accommodate foreign laws, regulations and practice. The Committee also may impose conditions on the exercise or vesting of Awards in order to minimize the Company’s or a
Subsidiary’s obligation with respect to tax equalization for Employees on assignments outside their home countries. Notwithstanding the discretion of the Committee under this section, the Participant remains solely liable for any applicable
personal taxes. 
 (q) Repricing Prohibited. Except as provided in Section 4(f), the terms of outstanding Options or Stock Appreciation Rights
may not be amended, and action may not otherwise be taken without stockholder approval, to: (i) reduce the exercise price of outstanding Options or Stock Appreciation Rights, (ii) cancel outstanding Options or Stock Appreciation Rights in
exchange for Options or Stock Appreciation Rights with an exercise price that is less than the exercise price of the original Options or Stock Appreciation Rights, or (iii) replace outstanding Options or Stock Appreciation Rights in exchange
for other Awards or cash at a time when the exercise price of such Options or Stock Appreciation Rights is higher than the Fair Market Value of a Share. 

(r) Deferral. The Committee may require or permit Participants to elect to defer the issuance of Shares or the settlement of Awards in cash or other
property to the extent that such deferral complies with Section 409A of the Code and any regulations or guidance promulgated thereunder. The Committee may also authorize the payment or crediting of interest, dividends or dividend equivalents on
any deferred amounts. 
 (s) Compliance with Section 409A of the Code. Except to the extent specifically provided otherwise by the
Committee and notwithstanding any other provision of the Plan, Awards under the Plan are intended to satisfy the requirements of Section 409A of the Code (and the Treasury Department guidance and regulations issued thereunder) so as to avoid
the imposition of any additional taxes or penalties under Section 409A of the Code. If the Committee determines that an Award, payment, distribution, transaction or any other action or arrangement contemplated by the provisions of the Plan
would, if undertaken, cause a Participant to become subject to any additional taxes or other penalties under Section 409A of the Code, then unless the Committee specifically provides otherwise, such Award, payment, distribution, transaction or
other action or arrangement shall not be given effect to the extent it causes such result and the related provisions of the Plan and/or Award Agreement will be deemed modified, or, if necessary, suspended in order to comply with the requirements of
Section 409A of the Code to the extent determined appropriate by the Committee, in each case without the consent of or notice to the Participant. Although the Company may attempt to avoid adverse tax treatment under Section 409A of the
Code, the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment. The Company shall be unconstrained in its corporate activities without regard to the potential
negative tax impact on holders of Awards under the Plan. 
 (t) Effect of Headings. The Section headings and subheadings herein are for convenience
of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof. 
 SECTION 16.
TERM OF PLAN. No Award shall be granted pursuant to the Plan after November 1, 2026 but any Award theretofore granted may extend beyond that date. The Plan became effective as of the Company’s separation from Alcoa Inc. on November 1, 2016.
