2013 Equity Incentive Plan



 Exhibit 10.07.01 

The ExOne Company 
 2013 EQUITY INCENTIVE PLAN 
 1. PURPOSE. The purpose of
this Plan is to provide incentives to attract, retain and motivate eligible persons whose present and potential contributions are important to the success of the Company and Subsidiaries (including those that exist now or in the future), by offering
them an opportunity to participate in the Company’s future performance through the grant of Awards. Capitalized terms not defined elsewhere in the text are defined in Section 27. 

2. SHARES SUBJECT TO THE PLAN. 
 2.1 Number of Shares Available. Subject to Sections 2.5 and 21 and any other adjustments provided for herein, the total number of Shares reserved and available for grant and issuance pursuant
to this Plan as of the date of adoption of the Plan by the Board, is 500,000 Shares. 
 2.2 Lapsed, Returned Awards.
Shares subject to Awards, and Shares issued under the Plan under any Award, will again be available for grant and issuance as subsequent Awards under this Plan to the extent such Shares: (a) were subject to issuance upon exercise of an Option
or SAR granted under this Plan but which ceased to be subject to the Option or SAR for any reason other than exercise of the Option or SAR; (b) were subject to Awards granted under this Plan that were forfeited or repurchased by the Company at
the original issue price; (c) were subject to Awards granted under this Plan that otherwise terminated without such Shares being issued; or (d) were surrendered pursuant to an Exchange Program. To the extent an Award under the Plan is paid
out in cash rather than Shares, such cash payment will not result in reducing the number of Shares available for issuance under the Plan. Shares used or withheld to pay the exercise price of an Award or to satisfy the tax withholding obligations
related to an Award will become available for future grant or sale under the Plan. For the avoidance of doubt, Shares that otherwise become available for grant and issuance because of the provisions of this Section 2.2 shall not include Shares
subject to Awards that initially became available because of the substitution clause in Section 21.2 hereof. 

2.3 Minimum Share Reserve. At all times the Company shall reserve and keep available a sufficient number of Shares as shall
be required to satisfy the requirements of all outstanding Awards granted under this Plan. 
 2.4 Automatic Share
Reserve Increase. The number of Shares available for grant and issuance under the Plan shall be increased on January 1 of each of the ten (10) calendar years during the term of the Plan, by the lesser of (i) three percent
(3%) of the number of Shares issued and outstanding on each December 31 immediately prior to the date of increase or (ii) such number of Shares determined by the Board. Notwithstanding the forgoing, the total number of shares
authorized under this Plan will not exceed fifteen percent (15%) of the number of Shares issued and outstanding in the aggregate as of the consummation of the Company’s initial public offering, subject to any adjustment pursuant to
Section 2.5. 
 2.5 Adjustment of Shares. If the number of outstanding Shares is changed by a stock dividend,
recapitalization, stock split, reverse stock split, subdivision, combination, reclassification or similar change in the capital structure of the Company, without consideration, then the Committee shall proportionately adjust (a) the number of
Shares reserved for issuance and future grant under the Plan set forth in Section 2.1, (b) the Exercise Prices of and number of Shares subject to outstanding Options and SARs, (c) the number of Shares subject to other outstanding
Awards, (d) the maximum number of Shares that may be issued to an individual or to a new Employee in any one calendar year set forth in Section 3 and (e) the number of Shares that are granted as Awards to Non-Employee Directors as set
forth in Section 12, subject to any required action by the Board or the stockholders of the Company and in compliance with applicable securities laws; provided that fractions of a Share will not be issued. 

Any such adjustment or other actions taken by the Committee pursuant to this Section 2.5 shall be performed in accordance with the
applicable provisions of the Code and regulations promulgated thereunder so as to not affect the status of (i) any Award intended to qualify as performance-based compensation under Section 162(m) of the Code, unless the Committee
determines otherwise, (ii) any Award intended to qualify as an ISO under Section 422 of the Code, unless the Committee determines otherwise or (iii) any Award intended to comply with, or qualify for an exception to, Section 409A
of the Code.

 3. ELIGIBILITY. ISOs may be granted only to Employees. All other Awards
may be granted to Employees, Consultants, Directors and Non-Employee Directors of the Company or any Subsidiary of the Company; provided such Consultants, Directors and Non-Employee Directors render bona fide services that are not
in connection with the offer and sale of securities in a capital-raising transaction. No Participant will be eligible to receive more than 100,000 Shares in any calendar year under this Plan pursuant to the grant of Awards except that new Employees
of the Company or of a Subsidiary of the Company (including new Employees who are also officers and directors of the Company or any Subsidiary of the Company) are eligible to receive up to a maximum of 500,000 Shares in the calendar year in which
they commence their employment. 
 4. ADMINISTRATION. 

4.1 Committee Composition; Authority. This Plan will be administered by the Committee or by the Board acting as the
Committee. Subject to the general purposes, terms and conditions of this Plan, and to the direction of the Board, the Committee will have full power to implement and carry out this Plan, except, however, the Board shall establish the terms for the
grant of an Award to Non-Employee Directors. The Committee will have the authority to: 
 (a) construe and interpret this Plan,
any Award Agreement and any other agreement or document executed pursuant to this Plan; 
 (b) prescribe, amend and rescind
rules and regulations relating to this Plan or any Award; 
 (c) select persons to receive Awards; 

(d) determine the form and terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms
and conditions include, but are not limited to, the exercise price, the time or times when Awards may vest and be exercised (which may be based on performance criteria), any vesting, acceleration or waiver of forfeiture restrictions, and any
restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Committee will determine; 
 (e) determine the number of Shares or other consideration subject to Awards; 

(f) determine the Fair Market Value in good faith and interpret the applicable provisions of this Plan and the definition of Fair Market
Value in connection with circumstances that impact the Fair Market Value, if necessary; 
 (g) determine whether Awards will be
granted singly, in combination with, in tandem with, in replacement of, or as alternatives to, other Awards under this Plan or any other incentive or compensation plan of the Company or any Subsidiary of the Company; 

(h) to modify or waive the terms and conditions of any Award that has been granted; 

(i) determine the vesting, exercisability and payment of Awards; 

(j) correct any defect, supply any omission or reconcile any inconsistency in this Plan, any Award or any Award Agreement; 

(k) determine whether an Award has been earned; 
 (l) determine the terms and conditions of any, and to institute any, Exchange Program; 
 (m) reduce or waive any criteria with respect to Performance Factors; 
 (n)
adjust Performance Factors to take into account changes in law and accounting or tax rules as the Committee deems necessary or appropriate to reflect the impact of extraordinary or unusual items, events or circumstances to avoid windfalls or
hardships provided that such adjustments are consistent with the regulations promulgated under Section 162(m) of the Code with respect to persons whose compensation is subject to Section 162(m) of the Code; 

(o) adopt rules and/or procedures (including the adoption of any subplan under this Plan) relating to the operation and administration
of the Plan to accommodate requirements of local law and procedures outside of the United States; 
 (p) make all other
determinations that it deems necessary or advisable for the administration of this Plan; and 
 (q) delegate any of the
foregoing as permitted by law to one or more executive officers pursuant to a specific delegation, in which case references to “Committee” in this Section 4.1 will refer to such delegate(s), except with respect to Insiders.

 4.2 Committee Interpretation and Discretion. Any determination made by the
Committee with respect to any Award shall be made in its sole discretion at the time of grant of the Award or, unless in contravention of any express term of the Plan or Award, at any later time, and such determination shall be final and binding on
the Company and all persons having an interest in any Award under the Plan. Any dispute regarding the interpretation of the Plan or any Award Agreement shall be submitted by the Participant or Company to the Committee for review. The resolution of
such a dispute by the Committee shall be final and binding on the Company and the Participant. The Committee may delegate to one or more executive officers the authority to review and resolve disputes with respect to Awards held by Participants who
are not Insiders, and such resolution shall be final and binding on the Company and the Participant, in which case references to “Committee” in this Section 4.2 will refer to such delegate(s). 

No member of the Committee and no officer of the Company shall be liable for anything done or omitted to be done by such member or
officer, by any other member of the Committee or by any other officer of the Company in connection with the performance of duties under this Plan, except for his or her own willful misconduct or as expressly provided by statute. In addition to all
other rights of indemnification and reimbursement to which a member of the Committee and an officer of the Company may be entitled, the Company shall indemnify and hold harmless each such member or officer who was or is a party or is threatened to
be made a party to any threatened, pending or completed proceeding or suit in connection with the performance of duties under this Plan against expenses (including reasonable attorneys’ fees), judgments, fines, liabilities, losses and amounts
paid in settlement actually and reasonably incurred by him or her in connection with such proceeding or suit, except for his or her own willful misconduct or as expressly provided otherwise by statute. Expenses (including reasonable attorneys’
fees) incurred by such a member or officer in defending any such proceeding or suit shall be paid by the Company in advance of the final disposition of such proceeding or suit upon receipt of a written affirmation by such member or officer of his or
her good faith belief that he or she has met the standard of conduct necessary for indemnification and a written undertaking by or on behalf of such member or officer to repay such amount if it shall ultimately be determined that he or she is not
entitled to be indemnified by the Company as authorized in this Section. 
 4.3 Section 162(m) of the Code and
Section 16 of the Exchange Act. When necessary or desirable for an Award to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee shall consist of at least two persons who are
“outside directors” (as defined under Section 162(m) of the Code) and at least two (or a majority if more than two then serve on the Committee) such “outside directors” shall approve the grant of such Award and timely
determine (as applicable) the Performance Period and any Performance Factors upon which vesting or settlement of any portion of such Award is to be subject. When required by Section 162(m) of the Code, prior to settlement of any such Award, at
least two (or a majority if more than two then serve on the Committee) such “outside directors” then serving on the Committee shall determine and certify in writing the extent to which such Performance Factors have been timely achieved and
the extent to which the Shares subject to such Award have thereby been earned. Awards granted to Participants who are subject to Section 16 of the Exchange Act must be approved by two or more “non-employee directors” (as defined in
the regulations promulgated under Section 16 of the Exchange Act). With respect to Participants whose compensation is subject to Section 162(m) of the Code, and provided that such adjustments are consistent with the regulations promulgated
under Section 162(m) of the Code, the Committee may adjust the performance goals to account for changes in law and accounting and to make such adjustments as the Committee deems necessary or appropriate to reflect the impact of extraordinary or
unusual items, events or circumstances to avoid windfalls or hardships, including without limitation (i) restructurings, discontinued operations, extraordinary items, and other unusual or non-recurring charges, (ii) an event either not
directly related to the operations of the Company or not within the reasonable control of the Company’s management, or (iii) a change in accounting standards required by generally accepted accounting principles. 

4.4 Documentation. The Award Agreement for a given Award, the Plan and any other documents may be delivered to, and accepted
by, a Participant or any other person in any manner (including electronic distribution or posting) that meets applicable legal requirements.

 5. OPTIONS. The Committee may grant Options to Participants and will
determine whether such Options will be Incentive Stock Options within the meaning of the Code (“ISOs”) or Nonqualified Stock Options (“NQSOs”), the number of Shares subject to the Option, the Exercise
Price of the Option, the period during which the Option may vest and be exercised, and all other terms and conditions of the Option, subject to the following: 
 5.1 Option Grant. Each Option Award granted under the Plan shall be evidenced by an Award Agreement which will specify whether the Option is an ISO or an NQSO. An Option Award may be, but need
not be, made subject to the satisfaction of Performance Factors during any Performance Period as are set out in advance in the Participant’s individual Award Agreement. If the Option is being earned upon the satisfaction of Performance Factors,
then the Committee will: (x) determine the nature, length and starting date of any Performance Period for each Option; and (y) select from among the Performance Factors to be used to measure the performance. Participants may participate
simultaneously with respect to multiple Options that are subject to different and possibly overlapping Performance Periods and different Performance Factors and other criteria. 

5.2 Date of Grant. The date of grant of an Option will be the date on which the Committee makes the determination to grant
such Option, or a specified future date. The Award Agreement and a copy of this Plan will be delivered to the Participant within a reasonable time after the granting of the Option. 

5.3 Exercise Period. Options may be vested and exercisable within the times or upon the conditions as set forth in the Award
Agreement governing such Option; provided, however, that no Option will be exercisable after the expiration of ten (10) years from the date the Option is granted; and provided further that no ISO granted to a
person who, at the time the ISO is granted, directly or by attribution owns more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of any Subsidiary of the Company (“Ten Percent
Stockholder”) will be exercisable after the expiration of five (5) years from the date the ISO is granted. The Committee also may provide for Options to become exercisable at one time or from time to time, periodically or
otherwise, in such number of Shares or percentage of Shares as the Committee determines. 
 5.4 Exercise Price. The
Exercise Price of an Option will be determined by the Committee when the Option is granted; provided that: (i) the Exercise Price of an Option will be not less than one hundred percent (100%) of the Fair Market Value of the Shares on the
date of grant and (ii) the Exercise Price of any ISO granted to a Ten Percent Stockholder will not be less than one hundred ten percent (110%) of the Fair Market Value of the Shares on the date of grant. Payment for the Shares purchased
may be made in accordance with Section 11 and the Award Agreement and in accordance with any procedures established by the Company. 
 5.5 Method of Exercise. Any Option granted hereunder will be vested and exercisable according to the terms of the Plan and at such times and under such conditions as determined by the
Committee and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. An Option will be deemed exercised when the Company receives: (i) notice of exercise (in such form as the Committee may specify from time
to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment may consist of any consideration and method
of payment authorized by the Committee and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant. Until the Shares are issued (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares, notwithstanding the exercise of the Option. The
Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in
Section 2.5 of the Plan. Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

 5.6 Termination. The exercise of an Option will be subject to the following (except as may be otherwise provided
in an Award Agreement): 
 (a) If the Participant is Terminated for any reason except for Cause or the Participant’s death
or Disability, then the Participant may exercise such Participant’s Options only to the extent that such Options would have been exercisable by the Participant on the Termination Date no later than ninety (90) days after the Termination
Date (or such shorter time period or longer time period not exceeding five (5) years as may be determined by the Committee, with any exercise beyond three (3) months after the Termination Date deemed to be the exercise of an NQSO), but in
any event no later than the expiration date of the Options. 
 (b) If the Participant is Terminated because of the
Participant’s death (or the Participant dies within ninety (90) days after a Termination other than for Cause or because of the Participant’s Disability), then the 

  
 4 








 
Participant’s Options may be exercised only to the extent that such Options would have been exercisable by the Participant on the Termination Date and must be exercised by the
Participant’s legal representative, or authorized assignee, no later than twelve (12) months after the Termination Date (or such shorter time period not less than six (6) months or longer time period not exceeding five (5) years
as may be determined by the Committee), but in any event no later than the expiration date of the Options. 
 (c) If the
Participant is Terminated because of the Participant’s Disability, then the Participant’s Options may be exercised only to the extent that such Options would have been exercisable by the Participant on the Termination Date and must be
exercised by the Participant (or the Participant’s legal representative or authorized assignee) no later than six (6) months after the Termination Date (with any exercise beyond (i) three (3) months after the Termination Date
when the Termination is for a Disability that is not a “permanent and total disability” as defined in Section 22(e)(3) of the Code, or (ii) twelve (12) months after the Termination Date when the Termination
is for a Disability that is a “permanent and total disability” as defined in Section 22(e)(3) of the Code, deemed to be exercise of an NQSO), but in any event no later than the expiration date of the Options.

 (d) If the Participant is terminated for Cause, then Participant’s Options shall expire on such Participant’s
Termination Date, or at such later time and on such conditions as are determined by the Committee, but in no event later than the expiration date of the Options. Unless otherwise provided in the Award Agreement, Cause will have the
meaning set forth in the Plan. 
 5.7 Limitations on Exercise. The Committee may specify a minimum number of Shares
that may be purchased on any exercise of an Option, provided that such minimum number will not prevent any Participant from exercising the Option for the full number of Shares for which it is then exercisable. 

5.8 Limitations on ISOs. With respect to Awards granted as ISOs, to the extent that the aggregate Fair Market Value of the
Shares with respect to which such ISOs are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated
as NQSOs. For purposes of this Section 5.8, ISOs will be taken into account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. In the
event that the Code or the regulations promulgated thereunder are amended after the Effective Date to provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, such different limit will be automatically
incorporated herein and will apply to any Options granted after the effective date of such amendment. 

5.9 Modification, Extension or Renewal. The Committee may modify, extend or renew outstanding Options and authorize the grant
of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant, impair any of such Participant’s rights under any Option previously granted. Any outstanding ISO that is modified,
extended, renewed or otherwise altered will be treated in accordance with Section 424(h) of the Code. Subject to Section 18 of this Plan, by written notice to affected Participants, the Committee may reduce the Exercise Price of
outstanding Options without the consent of such Participants; provided, however, that the Exercise Price may not be reduced below the Fair Market Value on the date the action is taken to reduce the Exercise Price. 

5.10 Delegation. The Committee may, to the extent permitted by applicable law, delegate to one or more executive officers pursuant
to a specific delegation authority to grant Options to Participants other than Insiders, subject to the provisions of this Section 5 (substituting references to “the Committee” by “the Committee’s delegate(s)” as the
context requires. 
 5.11 No Disqualification. Notwithstanding any other provision in this Plan, no term of this
Plan relating to ISOs will be interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under Section 422 of the Code or, without the consent of the Participant
affected, to disqualify any ISO under Section 422 of the Code. 
 6. RESTRICTED STOCK AWARDS.

 6.1 Awards of Restricted Stock. A Restricted Stock Award is an offer by the Company to sell to a Participant
Shares that are subject to restrictions (“Restricted Stock”). The Committee will determine to whom an offer will be made, the number of Shares the Participant may purchase, the Purchase Price, the restrictions under
which the Shares will be subject (including any vesting schedule) and all other terms and conditions of the Restricted Stock Award, subject to the Plan. 

  
 5 








 6.2 Restricted Stock Purchase Agreement. Each Restricted Stock Award
granted under the Plan shall be evidenced by an Award Agreement which will specify the terms and conditions of all purchases under the Award. Except as may otherwise be provided in an Award Agreement, a Participant accepts a Restricted Stock Award
by signing and delivering to the Company an Award Agreement with full payment of the Purchase Price, within thirty (30) days from the date the Award Agreement was delivered to the Participant. If the Participant does not accept such Award
within thirty (30) days, then the offer of such Restricted Stock Award will terminate, unless the Committee determines otherwise. 
 6.3 Purchase Price. The Purchase Price for a Restricted Stock Award will be determined by the Committee and may be less than Fair Market Value on the date the Restricted Stock Award is
granted. Payment of the Purchase Price must be made in accordance with Section 11 of the Plan, the Award Agreement and in accordance with any procedures established by the Company. 

6.4 Terms of Restricted Stock Awards. Restricted Stock Awards will be subject to such restrictions as the Committee may
impose or are required by law. These restrictions may be based on completion of a specified number of years of service with the Company or upon satisfaction of Performance Factors during any Performance Period as set out in advance in the
Participant’s Award Agreement. Prior to the grant of a Restricted Stock Award, the Committee shall: (a) determine the nature, length and starting date of any Performance Period for the Restricted Stock Award; (b) select from among the
Performance Factors to be used to measure performance goals, if any; and (c) determine the number of Shares that may be awarded to the Participant. Participants may participate simultaneously with respect to multiple Restricted Stock Awards
that are subject to different and possibly overlapping Performance Periods and different Performance Factors and other criteria. 
 6.5 Termination of Participant. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such Participant’s Termination Date (unless determined otherwise by
the Committee). 
 6.6 Delegation. The Committee may, to the extent permitted by applicable law, delegate to one or more
executive officers pursuant to a specific delegation authority to grant Restricted Stock Awards to Participants other than Insiders, subject to the provisions of this Section 6 (substituting references to “the Committee” by “the
Committee’s delegate(s)” as the context requires). 
 7. STOCK BONUS AWARDS. 

7.1 Awards of Stock Bonuses. A Stock Bonus Award is an award to an eligible person of Shares for services to be rendered or
for past services already rendered to the Company or any Subsidiary. Each Stock Bonus Award granted under the Plan shall be evidenced by an Award Agreement. No payment from the Participant will be required for Shares awarded pursuant to a Stock
Bonus Award. 
 7.2 Terms of Stock Bonus Awards. The Committee will determine the number of Shares to be awarded to
the Participant under a Stock Bonus Award and any restrictions thereon (including any vesting schedule). These restrictions may be based upon completion of a specified number of years of service with the Company or upon satisfaction of Performance
Factors during any Performance Period as set out in advance in the Participant’s Stock Bonus Agreement. Prior to the grant of any Stock Bonus Award the Committee shall: (a) determine the nature, length and starting date of any Performance
Period for the Stock Bonus Award; (b) select from among the Performance Factors to be used; and (c) determine the number of Shares that may be awarded to the Participant. Participants may participate simultaneously with respect to multiple
Stock Bonus Awards that are subject to different and possibly overlapping Performance Periods and different Performance Factors and other criteria. 
 7.3 Form of Payment to Participant. Stock Bonus Awards may be settled in cash, whole Shares, or a combination thereof, based on the Fair Market Value of the Shares earned under a Stock Bonus
Award on the date of payment, as determined in the sole discretion of the Committee. 
 7.4 Termination of
Participation. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such Participant’s Termination Date (unless determined otherwise by the Committee). 

7.5 Delegation. The Committee may, to the extent permitted by applicable law, delegate to one or more executive officers pursuant
to a specific delegation authority to grant Stock Bonus Awards to Participants other than Insiders, subject to the provisions of this Section 7 (substituting references to “the Committee” by “the Committee’s
delegate(s)” as the context requires).

 8. STOCK APPRECIATION RIGHTS. 

8.1 Awards of SARs. A Stock Appreciation Right (“SAR”) Award is an award to a Participant that may be
settled in cash, or Shares (which may consist of Restricted Stock), having a value equal to (a) the difference between the Fair Market Value on the date of exercise over the Exercise Price multiplied by (b) the number of Shares with
respect to which the SAR Award is being settled (subject to any maximum number of Shares that may be issuable as specified in an Award Agreement). Each SAR Award granted under the Plan shall be evidenced by an Award Agreement. 

8.2 Terms of SARs. The Committee will determine the terms of each SAR Award including, without limitation: (a) the
number of Shares subject to the SAR Award; (b) the Exercise Price and the time or times during which the SARs may be settled (including the vesting schedule); (c) the consideration to be distributed on settlement of the SAR Award; and
(d) the effect of the Participant’s Termination on each SAR Award. The Exercise Price of the SARs will be determined by the Committee when the SARs are granted, and may not be less than Fair Market Value. A SAR Award may be, but need not
be, made subject to the satisfaction of Performance Factors during any Performance Period as are set out in advance in the Participant’s individual Award Agreement. If the SARs are being earned upon the satisfaction of Performance Factors, then
the Committee will: (x) determine the nature, length and starting date of any Performance Period for the SAR Award; and (y) select from among the Performance Factors to be used. Participants may participate simultaneously with respect to
multiple SAR Awards that are subject to different and possibly overlapping Performance Periods and different Performance Factors and other criteria. 
 8.3 Exercise Period and Expiration Date. SARs will be exercisable within the time period or upon the occurrence of events determined by the Committee and set forth in the Award Agreement
governing such SARs. The SAR Award Agreement shall set forth the expiration date; provided that no SAR will be exercisable after the expiration of ten (10) years from the date the SAR is granted. The Committee may also provide for SARs to
become exercisable all at one time or from time to time, periodically or otherwise (including, without limitation, following any Performance Period upon the attainment of the applicable Performance Factors), in such number of Shares or percentage of
the Shares subject to the SAR Award as the Committee determines. 
 8.4 Form of Settlement. Upon exercise of a SAR,
a Participant will be entitled to receive payment from the Company in an amount determined by multiplying (i) the difference between the Fair Market Value of a Share on the date of exercise over the Exercise Price; times (ii) the number of
Shares with respect to which the SAR is exercised. At the discretion of the Committee, the payment from the Company for the SAR exercise may be in cash, in Shares of equivalent value, or in some combination thereof. The portion of a SAR being
settled may be paid currently or on a deferred basis with such interest or dividend equivalent, if any, as the Committee determines, provided that the terms of the SAR and any deferral satisfy the requirements of Section 409A of the Code.

 8.5 Termination of Participation. Except as may be set forth in the Participant’s Award Agreement, vesting
ceases on such Participant’s Termination Date (unless determined otherwise by the Committee). Notwithstanding the foregoing, the termination provisions set forth in Section 5.6 will also apply to SARs. 

8.6 Delegation. The Committee may, to the extent permitted by applicable law, delegate to one or more executive officers pursuant
to a specific delegation authority to grant SARs to Participants other than Insiders, subject to the provisions of this Section 8 (substituting references to “the Committee” by “the Committee’s delegate(s)” as the
context requires. 
 9. RESTRICTED STOCK UNITS. 

9.1 Awards of Restricted Stock Units. A Restricted Stock Unit (“RSU”) Award is an award to a
Participant covering a number of Shares that may be settled in cash, or by issuance of those Shares (which may consist of Restricted Stock). Each RSU Award granted under the Plan shall be evidenced by an Award Agreement. 

9.2 Terms of RSUs. The Committee will determine the terms of an RSU Award including, without limitation: (a) the number
of Shares subject to the RSU Award; (b) the time or times during which the RSUs may be settled (including the vesting schedule); (c) the consideration to be distributed on settlement; and (d) the effect of the Participant’s
Termination on the RSU Award. A RSU Award may be, but need not be, made subject to the satisfaction of Performance Factors during any Performance Period as are set out in advance in the Participant’s individual Award Agreement. If the RSU Award
is being earned upon satisfaction of Performance Factors, then the Committee will: (x) determine the nature, length and starting date of any Performance Period for the RSU Award; (y) select from among the Performance Factors to be used to
measure the performance; and (z) determine the number of Shares deemed subject to the RSU Award. Participants may participate simultaneously with respect to multiple RSU Awards that are subject to different and possibly overlapping Performance
Periods and different Performance Factors and other criteria. 

  
 7 








 9.3 Form and Timing of Settlement. Payment of earned RSUs shall be made as soon
as practicable after the date(s) determined by the Committee and set forth in the Award Agreement. The Committee, in its sole discretion, may settle earned RSUs in cash, Shares, or a combination of both. The Committee may also permit a Participant
to defer payment under a RSU Award to a date or dates after the RSUs are earned provided that the terms of any such deferral satisfy the requirements of Section 409A of the Code. 

9.4 Termination of Participant. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such
Participant’s Termination Date (unless determined otherwise by the Committee). 
 9.5 Delegation. The Committee may,
to the extent permitted by applicable law, delegate to one or more executive officers pursuant to a specific delegation authority to grant RSUs to Participants other than Insiders, subject to the provisions of this Section 9 (substituting
references to “the Committee” by “the Committee’s delegate(s)” as the context requires). 

10. PERFORMANCE AWARDS. 
 10.1 Performance Awards. A Performance Award is an award to a Participant of a cash bonus or a Performance Share bonus. Each Performance Award granted under the Plan shall be evidenced by an
Award Agreement. 
 10.2 Terms of Performance Awards. The Committee will determine, and each Award Agreement shall
set forth, the terms of each Performance Award including, without limitation: (a) the amount of cash bonus or the number of Shares deemed subject to the Performance Share Award; (c) the Performance Factors and Performance Period that shall
determine the time and extent to which each Performance Award shall be settled; (d) the consideration to be distributed on settlement; and (e) the effect of the Participant’s Termination on each Performance Award. In establishing
Performance Factors and the Performance Period the Committee will: (x) determine the nature, length and starting date of any Performance Period; and (y) select from among the Performance Factors to be used. Prior to settlement the
Committee shall determine the extent to which Performance Awards have been earned. Participants may participate simultaneously with respect to multiple Performance Awards that are subject to different and possibly overlapping Performance Periods and
different Performance Factors and other criteria. No Participant will be eligible to receive more than $10,000,000 in Performance Awards in any calendar year under this Plan. 
 10.3 Value, Earning and Timing of Performance Shares. Any Performance Share Award will have an initial value equal to the Fair Market Value of a Share on the date of grant. After the
applicable Performance Period has ended, the holder of a Performance Share Award will be entitled to receive a payout of the number of Performance Shares earned by the Participant over the Performance Period, to be determined as a function of the
extent to which the corresponding Performance Factors or other vesting provisions have been achieved. The Committee, in its sole discretion, may settle the earned Performance Shares in the form of cash, in Shares (which have an aggregate Fair Market
Value equal to the value of the earned Performance Shares at the close of the applicable Performance Period) or in a combination thereof. Earned Performance Shares may also be settled in Restricted Stock. 

10.4 Termination of Participant. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such
Participant’s Termination Date (unless determined otherwise by the Committee). 
 10.5 Delegation. The Committee
may, to the extent permitted by applicable law, delegate to one or more executive officers pursuant to a specific delegation authority to grant Performance Awards to Participants other than Insiders, subject to the provisions of this Section 10
(substituting references to “the Committee” by “the Committee’s delegate(s)” as the context requires).

 11. PAYMENT FOR SHARE PURCHASES. 

Payment from a Participant for Shares purchased pursuant to this Plan may be made in cash or by check or, where expressly approved for
the Participant by the Committee and where permitted by law (and to the extent not otherwise set forth in the applicable Award Agreement): 
 (a) by cancellation of indebtedness of the Company to the Participant; 
 (b) by
surrender of shares of the Company held by the Participant that have a Fair Market Value on the date of surrender or shares subject to the Award equal to the aggregate exercise price of the Shares as to which said Award will be exercised or settled;

 (c) by waiver of compensation due or accrued to the Participant for services rendered or to be rendered to the Company or a
Subsidiary of the Company; 
 (d) by consideration received by the Company pursuant to a broker-assisted or other form of

12. GRANTS TO NON-EMPLOYEE DIRECTORS. 
 12.1 Types of Awards. Non-Employee Directors are eligible to receive any type of Award offered under this Plan except ISOs. Awards pursuant to this Section 12 may be automatically made
pursuant to any policy adopted by the Board, or made from time to time as determined in the discretion of the Board. 

12.2 Eligibility. Awards pursuant to this Section 12 shall be granted only to Non-Employee Directors. A Non-Employee
Director who is elected or re-elected as a member of the Board will be eligible to receive an Award under this Section 12. 

12.3 Vesting, Exercisability and Settlement. Except as set forth in Section 21, Awards shall vest, become exercisable
and be settled as determined by the Board. With respect to Options and SARs, the exercise price granted to Non-Employee Directors shall not be less than the Fair Market Value of the Shares underlying such Award at the time that such Option or SAR is
granted. 
 12.4 Election to receive Awards in Lieu of Cash. A Non-Employee Director may elect to receive his or her
annual retainer payments and/or meeting fees from the Company in the form of cash or Awards or a combination thereof, as determined by the Committee. Such Awards shall be issued under the Plan. An election under this Section 12.4 shall be filed
with the Company on the form prescribed by the Company. 
 13. WITHHOLDING TAXES. 

13.1 Withholding Generally. Whenever Shares are to be issued in satisfaction of Awards granted under this Plan, the Company
may require the Participant to remit to the Company, or to the Subsidiary employing the Participant, an amount sufficient to satisfy applicable U.S. federal, state, local and international withholding tax requirements or any other tax liability
legally due from the Participant prior to the delivery of Shares pursuant to exercise or settlement of any Award. Whenever payments in satisfaction of Awards granted under this Plan are to be made in cash, such payment will be net of an amount
sufficient to satisfy applicable U.S. federal, state, local and international withholding tax requirements or any other tax liability legally due from the Participant. 
 13.2 Stock Withholding. The Committee, in its sole discretion and pursuant to such procedures as it may specify from time to time and to limitations of local law, may require or permit a
Participant to satisfy such tax withholding obligation or any other tax liability legally due from the Participant, in whole or in part, by (without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise
deliverable cash or Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld, or (iii) delivering to the Company already-owned Shares having a Fair Market Value equal to the minimum amount required to be
withheld. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld.

 14. TRANSFERABILITY. 

14.1 Transfer Generally. Unless determined otherwise by the Committee or pursuant to Section 14.2, an Award may not be
sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution. If the Committee makes an Award transferable, including, without limitation, by instrument to an inter
vivos or testamentary trust in which the Awards are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift to a Permitted Transferee, such Award will contain such additional terms and conditions as the Committee or its
delegate(s) deems appropriate. All Awards shall be exercisable: (i) during the Participant’s lifetime only by (A) the Participant, or (B) the Participant’s guardian or legal representative; (ii) after the
Participant’s death, by the legal representative of the Participant’s heirs or legatees; and (iii) in the case of all awards except ISOs, by a Permitted Transferee (for awards made transferrable by the Committee or its delegate(s)),
or to such person’s guardian or legal representative. 
 14.2 Award Transfer Program. Notwithstanding any
contrary provision of the Plan, the Committee shall have all discretion and authority to determine and implement the terms and conditions of any Award Transfer Program instituted pursuant to this Section 14.2 and shall have the authority to
amend the terms of any Award participating, or otherwise eligible to participate in, the Award Transfer Program, including (but not limited to) the authority to (i) amend (including to extend) the expiration date, post-termination exercise
period and/or forfeiture conditions of any such Award, (ii) amend or remove any provisions of the Award relating to the Award holder’s continued service to the Company, (iii) amend the permissible payment methods with respect to
the exercise or purchase of any such Award, (iv) amend the adjustments to be implemented in the event of changes in the capitalization and other similar events with respect to such Award, and (v) make such other changes to the terms of
such Award as the Committee deems necessary or appropriate in its sole discretion. 
 15. PRIVILEGES OF STOCK
OWNERSHIP. No Participant will have any of the rights of a stockholder with respect to any Shares until the Shares are issued to the Participant, except for any dividend equivalent rights permitted by an applicable Award Agreement. After
Shares are issued to the Participant, the Participant will be a stockholder and have all the rights of a stockholder with respect to such Shares, including the right to vote and receive all dividends or other distributions made or paid with respect
to such Shares; provided, that if such Shares are Restricted Stock, then any new, additional or different securities the Participant may become entitled to receive with respect to such Shares by virtue of a stock dividend, stock split or
any other change in the corporate or capital structure of the Company will be subject to the same restrictions as the Restricted Stock; provided, further, that the Participant will have no right to retain such stock dividends
or stock distributions with respect to Shares that are repurchased by the Company. 

16. CERTIFICATES. All Shares or other securities whether or not certificated, delivered under this Plan will be
subject to such stock transfer orders, legends and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable U.S. federal, state or foreign securities law, or any rules, regulations and other
requirements of the SEC or any stock exchange or automated quotation system upon which the Shares may be listed or quoted and any non-U.S. exchange controls or securities law restrictions to which the Shares are subject. 

17. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a Participant’s Shares, the Committee may
require the Participant to deposit all certificates representing Shares, together with stock powers or other instruments of transfer approved by the Committee, appropriately endorsed in blank, with the Company or an agent designated by the Company
to hold in escrow until such restrictions have lapsed or terminated, and the Committee may cause a legend or legends referencing such restrictions to be placed on the certificates. Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be required to pledge and deposit with the Company all or part of the Shares so purchased as collateral to secure the payment of the Participant’s obligation to the
Company under the promissory note; provided, however, that the Committee may require or accept other or additional forms of collateral to secure the payment of such obligation and, in any event, the Company will have full
recourse against the Participant under the promissory note notwithstanding any pledge of the Participant’s Shares or other collateral. In connection with any pledge of the Shares, the Participant will be required to execute and deliver a
written pledge agreement in such form as the Committee will from time to time approve. The Shares purchased with the promissory note may be released from the pledge on a pro rata basis as the promissory note is paid. 

18. REPRICING; EXCHANGE AND BUYOUT OF AWARDS. Without prior stockholder approval the Committee may
(i) reprice Options or SARS (and where such repricing is a reduction in the Exercise Price of outstanding Options or SARS, the consent of the affected Participants is not required provided written notice is provided to them,
notwithstanding any adverse tax consequences to them arising from the repricing), and (ii) with the consent of the respective Participants (unless not required pursuant to Section 5.9 of the Plan), pay cash or issue new Awards in exchange
for the surrender and cancellation of any, or all, outstanding Awards. 

  
 10 









 19. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award will
not be effective unless such Award is in compliance with all applicable U.S. and foreign federal and state securities laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon
which the Shares may then be listed or quoted, as they are in effect on the date of grant of the Award and also on the date of exercise or other issuance. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue
or deliver certificates for Shares under this Plan prior to: (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable; and/or (b) completion of any registration or other qualification of
such Shares under any state or federal or foreign law or ruling of any governmental body that the Company determines to be necessary or advisable. 
 20. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted under this Plan will confer or be deemed to confer on any Participant any right to continue in the employ
of, or to continue any other relationship with, the Company or any Subsidiary of the Company or limit in any way the right of the Company or any Subsidiary of the Company to terminate Participant’s employment or other relationship at any time.

 21. CORPORATE TRANSACTIONS. 

21.1 Participant Awards. (a) In the event that the Company is party to any merger or consolidation contemplated in
subsection (iii) of the definition of “Corporate Transactions,” all Shares paid out under the Plan and all Awards subject to the Plan at such time will be subject to the agreement of merger or consolidation. Such agreement need not
treat all Awards in an identical manner, but shall provide for one or more of the following treatments with respect to each Award: 
 (1) The continuation of the Award by the Company (if the Company is the surviving corporation). 
 (2) The assumption of the Award by the surviving corporation or its Parent and, with respect to an Award that is subject to Section 409A of the Code, in a manner that complies with
Section 424(a) of the Code (whether or not the Award is an ISO). 
 (3) The substitution by the surviving corporation or
its Parent of a new Award, and with respect to an Award that is subject to Section 409A of the Code, in a manner that complies with Section 424(a) of the Code (whether or not the Award is an ISO). 

(4) Full exercisability of an Option, full vesting of the Shares subject to an Option and/or full vesting of all other Awards, followed
by the cancellation of the Option or Award. The full exercisability of an Option, full vesting of the Shares subject to the Option and/or full vesting of all other Awards may be contingent on the closing of such merger or consolidation. The
Participant will be able to exercise an Option during a period of not less than five (5) full business days preceding the effective date of such merger or consolidation, unless (A) a shorter period is required to permit a timely closing of
such merger or consolidation and (B) such shorter period still offers the Participant a reasonable opportunity to exercise an Option. Any exercise of an Option during such period may be contingent on the closing of such merger or consolidation.

 (5) A payment to the Participant equal to the excess of (A) the Fair Market Value of the Shares subject to the Award as
of the effective date of such merger or consolidation over (B) the Exercise Price or Purchase Price of Shares, as the case may be, subject to the Award in connection with the cancellation of the Award. Such payment will be made in the form of
cash, cash equivalents, or securities of the surviving corporation or its Parent with a Fair Market Value equal to the required amount. The successor corporation may provide substantially similar consideration to Participants as was provided to
stockholders (after taking into account the existing provisions of the Awards). Subject to Section 409A of the Code, such payment may be made in installments and may be deferred until the date or dates when the Award would have become
exercisable or such Shares would have vested. The amount of such payment initially will be calculated without regard to whether or not the Award is then exercisable or such Shares are then vested. However, such payment may be subject to vesting
based on the Participant’s continuing service as an Employee, Consultant or Director. In addition, any escrow, holdback, earn out or similar provisions in the agreement of merger or consolidation may apply to such payment to the same extent and
in the same manner as such provisions apply to the holders of Shares. If the Exercise Price of the Shares subject to an option exceeds the Fair Market Value of such Shares, then the Option may be cancelled without making a payment to the
Participant. For purposes of this subsection, the Fair Market Value of any security will be determined without regard to any vest conditions that may apply to such security. 

  
 11 









 (b) Notwithstanding any provision to the contrary herein, in the event of a Corporate
Transaction other than as defined in subsection (iii) of the definition of “Corporate Transaction,” the vesting of all Awards granted to Participants will accelerate and such Awards will become exercisable (as applicable) in full
prior to the consummation of such event at such times and on such conditions as the Committee determines. 
 (c) Any adjustment
or other actions taken by the Committee pursuant to this Section 21.1 shall be performed in accordance with the applicable provisions of the Code and regulations promulgated thereunder so as to not affect the status of (i) any Award
intended to qualify as performance-based compensation under Section 162(m) of the Code, unless the Committee determines otherwise, (ii) any Award intended to qualify as an ISO under Section 422 of the Code, unless the Committee
determines otherwise, or (iii) any Award intended to comply with, or qualify for an exception to, Section 409A of the Code. 
 21.2 Assumption of Awards by the Company. The Company, from time to time, also may substitute or assume outstanding awards granted by another company, whether in connection with an acquisition
of such other company or otherwise, by either; (a) granting an Award under this Plan in substitution of such other company’s award; or (b) assuming such award as if it had been granted under this Plan if the terms of such assumed
award could be applied to an Award granted under this Plan. Such substitution or assumption will be permissible if the holder of the substituted or assumed award would have been eligible to be granted an Award under this Plan if the other company
had applied the rules of this Plan to such grant. In the event the Company assumes an award granted by another company, the terms and conditions of such award will remain unchanged (except that the Purchase Price or the Exercise Price, as the
case may be, and the number and nature of Shares issuable upon exercise or settlement of any such Award will be adjusted appropriately pursuant to Section 424(a) of the Code). In the event the Company elects to grant a new Option in
substitution rather than assuming an existing option, such new Option may be granted with a similarly adjusted Exercise Price. Substitute Awards will not reduce the number of Shares authorized for grant from the Plan or authorized for grant to a
Participant in any calendar year. 
 21.3 Non-Employee Directors’ Awards. Notwithstanding any provision to the
contrary herein, in the event of a Corporate Transaction, the vesting of all Awards granted to Non-Employee Directors will accelerate and such Awards will become exercisable (as applicable) in full prior to the consummation of such event at such
times and on such conditions as the Committee determines. 
 22. ADOPTION AND STOCKHOLDER APPROVAL.
This Plan shall be submitted for the approval of the Company’s stockholders, consistent with applicable laws, within twelve (12) months after the date this Plan is adopted by the Board. 

23. TERM OF PLAN/GOVERNING LAW. Unless earlier terminated as provided herein, this Plan will become effective
on the Effective Date and will terminate ten (10) years from the date this Plan is adopted by the Board. This Plan and all Awards granted hereunder shall be governed by and construed in accordance with the laws of the State of Delaware without
regard to its conflict of laws provisions. 
 24. AMENDMENT OR TERMINATION OF PLAN. The Board may at
any time terminate or amend this Plan in any respect, including, without limitation, amendment of any form of Award Agreement or instrument to be executed pursuant to this Plan; provided, however, that the Board will not,
without the approval of the stockholders of the Company, amend this Plan in any manner that requires such stockholder approval; provided further, that a Participant’s Award shall be governed by the version of this Plan then in
effect at the time such Award was granted. 
 25. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of
this Plan by the Board, the submission of this Plan to the stockholders of the Company for approval, nor any provision of this Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the granting of stock awards and bonuses otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only in specific cases. 

26. INSIDER TRADING POLICY. Each Participant who receives an Award shall comply with any policy adopted by the
Company from time to time covering transactions in the Company’s securities by Employees, officers and/or directors of the Company.

 “Stock Appreciation Right” means an Award granted pursuant to Section 8 or
Section 12 of the Plan. 
 “Stock Bonus Award” means an Award granted pursuant to
Section 7 or Section 12 of the Plan. 
 “Subsidiary” means any corporation (other than the
Company) in an unbroken chain of corporations beginning with the Company if each of the corporations other than the last corporation in the unbroken chain owns stock possessing fifty percent (50%) or more of the total combined voting power of
all classes of stock in one of the other corporations in such chain. 
 “Termination” or
“Terminated” means, for purposes of this Plan with respect to a Participant, that the Participant has for any reason ceased to provide services as an employee, officer, director, consultant, independent contractor or advisor
to the Company or a Subsidiary of the Company. An employee will not be deemed to have ceased to provide services in the case of (i) sick leave, (ii) military leave, or (iii) any other leave of absence approved by the
Committee; provided, that such leave is for a period of not more than 90 days, unless reemployment upon the expiration of such leave is guaranteed by contract or statute or unless provided otherwise pursuant to formal policy adopted from
time to time by the Company and issued and promulgated to employees in writing. In the case of any employee on an approved leave of absence, the Committee may make such provisions respecting suspension of vesting of the Award while on leave from the
employ of the Company or a Subsidiary of the Company as it may deem appropriate, except that in no event may an Award be exercised after the expiration of the term set forth in the applicable Award Agreement. In the event of military leave, if
required by applicable laws, vesting shall continue for the longest period that vesting continues under any other statutory or Company approved leave of absence and, upon a Participant’s returning from military leave (under conditions that
would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Awards to the same extent as would have applied had the Participant
continued to provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such leave. An employee shall have terminated employment as of the date he or she ceases to be employed
(regardless of whether the termination is in breach of local laws or is later found to be invalid) and employment shall not be extended by any notice period or garden leave mandated by local law. The Committee will have sole discretion to determine
whether a Participant has ceased to provide services for purposes of the Plan and the effective date on which the Participant ceased to provide services (the “Termination Date”). 

“Unvested Shares” means Shares that have not yet vested or are subject to a right of repurchase in favor of the
Company (or any successor thereto).
