GRANT OF OPTION 
 2.1 Grant of Option. In consideration of Participant’s past and/or continued employment with or service to the Company or a Subsidiary and for other good and valuable consideration, effective

except to the extent expressly provided otherwise in a written agreement between the Company or a Subsidiary and Participant. 

 ARTICLE 3.
 PERIOD OF EXERCISABILITY 
 3.1 Commencement of Exercisability.

 (a) Subject to Sections 3.2, 3.3, 5.8 and 5.14 hereof, the Option shall become vested and exercisable in such amounts and at
such times as are set forth in the Grant Notice. 
 (b) No portion of the Option which has not become vested and exercisable at
the date of Participant’s Termination of Service shall thereafter become vested and exercisable, except as may be otherwise provided by the Administrator or as set forth in a written agreement between the Company and Participant. 

3.2 Duration of Exercisability. The installments provided for in the vesting schedule set forth in the Grant Notice are
cumulative. Each such installment which becomes vested and exercisable pursuant to the vesting schedule set forth in the Grant Notice shall remain vested and exercisable until it becomes unexercisable under Section 3.3 hereof. 

3.3 Expiration of Option. The Option may not be exercised to any extent by anyone after the first to occur of the following
events: 
 (a) The expiration date set forth in the Grant Notice; 

(b) Except as the Administrator may otherwise approve, in the event of Participant’s Termination of Service other than for Cause or
by reason of Participant’s death or disability, the expiration of three (3) months from the date of Participant’s Termination of Service; 
 (c) Except as the Administrator may otherwise approve, the expiration of one (1) year from the date of Participant’s Termination of Service by reason of Participant’s death or disability;
or 
 (d) Except as the Administrator may otherwise approve, upon Participant’s Termination of Service for Cause.

 As used in this Agreement, “Cause” shall mean (a) the Board’s determination that Participant failed to
substantially perform his or her duties (other than any such failure resulting from Participant’s disability); (b) the Board’s determination that Participant failed to carry out, or comply with any lawful and reasonable directive of
the Board or Participant’s immediate supervisor; (c) Participant’s conviction, plea of no contest, plea of nolo contendere, or imposition of unadjudicated probation for any felony, indictable offense or crime involving moral
turpitude; (d) Participant’s unlawful use (including being under the influence) or possession of illegal drugs on the Company’s (or any Subsidiary’s) premises or while performing Participant’s duties and responsibilities; or
(e) Participant’s commission of an act of fraud, embezzlement, misappropriation, misconduct, or breach of fiduciary duty against the Company or any Subsidiary. Notwithstanding the foregoing, if Participant is a party to a written
employment or consulting agreement with the Company (or any Subsidiary), then “Cause” shall be as such term is defined in the applicable written employment or consulting agreement. 

3.4 Tax Withholding. Notwithstanding any other provision of this Agreement: 

(a) The Company and its Subsidiaries have the authority to deduct or withhold, or require Participant to remit to the Company or the
applicable Subsidiary, an amount sufficient to satisfy applicable federal, state, local and foreign taxes (including the employee portion of any FICA obligation) required by law to be withheld with respect to any taxable event arising pursuant to
this Agreement. The Company and its Subsidiaries may withhold or Participant may make such payment in one or more of the forms specified below: 

  
 A-2

 (i) by cash or check made payable to the Company or the Subsidiary with respect to which
the withholding obligation arises; 
 (ii) by the deduction of such amount from other compensation payable to Participant;

 (iii) with respect to any withholding taxes arising in connection with the exercise of the Option, with the consent of the
Administrator, by requesting that the Company withhold a net number of shares of Stock issuable upon the exercise of the Option having a then current Fair Market Value not exceeding the amount necessary to satisfy the withholding obligation of the
Company and its Subsidiaries based on the minimum applicable statutory withholding rates for federal, state, local and foreign income tax and payroll tax purposes; 
 (iv) with respect to any withholding taxes arising in connection with the exercise of the Option, with the consent of the Administrator, by tendering to the Company shares of Stock having a then current
Fair Market Value not exceeding the amount necessary to satisfy the withholding obligation of the Company and its Subsidiaries based on the minimum applicable statutory withholding rates for federal, state, local and foreign income tax and payroll
tax purposes; 
 (v) with respect to any withholding taxes arising in connection with the exercise of the Option, through the
delivery of a notice that Participant has placed a market sell order with a broker acceptable to the Company with respect to shares of Stock then issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion
of the net proceeds of the sale to the Company or the Subsidiary with respect to which the withholding obligation arises in satisfaction of such withholding taxes; provided that payment of such proceeds is then made to the Company or the
applicable Subsidiary at such time as may be required by the Administrator, but in any event not later than the settlement of such sale; or 
 (vi) in any combination of the foregoing. 
 (b) With respect to any withholding
taxes arising in connection with the Option, in the event Participant fails to provide timely payment of all sums required pursuant to Section 3.4(a), the Company shall have the right and option, but not the obligation, to treat such failure as
an election by Participant to satisfy all or any portion of Participant’s required payment obligation pursuant to Section 3.4(a)(ii) or Section 3.4(a)(iii) above, or any combination of the foregoing as the Company may determine to be
appropriate. The Company shall not be obligated to deliver any certificate representing shares of Stock issuable with respect to the exercise of the Option to Participant or his or her legal representative unless and until Participant or his or her
legal representative shall have paid or otherwise satisfied in full the amount of all federal, state, local and foreign taxes applicable with respect to the taxable income of Participant resulting from the exercise of the Option or any other taxable
event related to the Option. 
 (c) In the event any tax withholding obligation arising in connection with the Option will be
satisfied under Section 3.4(a)(iii) above, then the Company may elect to instruct any brokerage firm determined acceptable to the Company for such purpose to sell on Participant’s behalf a whole number of shares from those shares of Stock
that are issuable upon exercise of the Option as the Company determines to be appropriate to generate cash proceeds sufficient to satisfy the tax withholding obligation and to remit the proceeds of such sale to the Company or the Subsidiary with
respect to which the withholding obligation arises. Participant’s acceptance of this Award constitutes Participant’s instruction and authorization to the Company and such brokerage firm to complete the transactions described in this
Section 3.4(c), including the transactions described in the previous sentence, as applicable. The Company may refuse to issue any shares of Stock to Participant until the foregoing tax withholding obligations are satisfied. 

  
 A-3

 (d) Participant is ultimately liable and responsible for all taxes owed in connection with
the Option, regardless of any action the Company or any Subsidiary takes with respect to any tax withholding obligations that arise in connection with the Option. Neither the Company nor any Subsidiary makes any representation or undertaking
regarding the treatment of any tax withholding in connection with the awarding, vesting or exercise of the Option or the subsequent sale of Stock. The Company and the Subsidiaries do not commit and are under no obligation to structure the Option to
reduce or eliminate Participant’s tax liability. 
 ARTICLE 4. 

EXERCISE OF OPTION 
 4.1 Person Eligible to Exercise. During the lifetime of Participant, only Participant may exercise the Option or any portion thereof. After the death of Participant, any exercisable portion of the
Option may, prior to the time when the Option becomes unexercisable under Section 3.3 hereof, be exercised by Participant’s personal representative or by any person empowered to do so under the deceased Participant’s will or under the
then applicable laws of descent and distribution. 
 4.2 Partial Exercise. Subject to Section 5.2, any exercisable
portion of the Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time prior to the time when the Option or portion thereof becomes unexercisable under Section 3.3 hereof. 

4.3 Manner of Exercise. Subject to Section 5.7 of the Plan, the Option, or any exercisable portion thereof, may be exercised

thereof becomes unexercisable under Section 3.3 hereof: 
 (a) An exercise notice in a form specified by the Administrator,
stating that the Option or portion thereof is thereby exercised, such notice complying with all applicable rules established by the Administrator; 
 (b) The receipt by the Company of full payment for the shares of Stock with respect to which the Option or portion thereof is exercised, in such form of consideration permitted under Section 4.4
hereof that is acceptable to the Administrator; 
 (c) The payment of any applicable withholding tax in accordance with
Section 3.4; 
 (d) Any other written representations or documents as may be required in the Administrator’s sole
discretion to effect compliance with Applicable Law; and 
 (e) In the event the Option or portion thereof shall be exercised
pursuant to Section 4.1 hereof by any person or persons other than Participant, appropriate proof of the right of such person or persons to exercise the Option. 
 Notwithstanding any of the foregoing, the Administrator shall have the right to specify all conditions of the manner of exercise, which conditions may vary by country and which may be subject to change
from time to time.

following, or a combination thereof, at the election of Participant: 
 (a) Cash or check; 

(b) With the consent of the Administrator, surrender of shares of Stock (including, without limitation, shares of Stock otherwise
issuable upon exercise of the Option) held for such period of time as may be required by the Administrator in order to avoid adverse accounting consequences and having a Fair Market Value on the date of delivery equal to the aggregate exercise price
of the Option or exercised portion thereof; 
 (c) Through the delivery of a notice that Participant has placed a market sell
order with a broker acceptable to the Company with respect to shares of Stock then issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction
of the Option exercise price; provided that payment of such proceeds is then made to the Company at such time as may be required by the Administrator, but in any event not later than the settlement of such sale; or 

(d) Any other form of legal consideration acceptable to the Administrator. 

4.5 Conditions to Issuance of Stock. The Company shall not be required to issue or deliver any shares of Stock purchased upon the
exercise of the Option or portion thereof prior to fulfillment of all of the following conditions: (A) the admission of such shares of Stock to listing on all stock exchanges on which such Stock is then listed, (B) the completion of any
registration or other qualification of such shares of Stock under any state or federal law or under rulings or regulations of the Securities and Exchange Commission or other governmental regulatory body, which the Administrator shall, in its
absolute discretion, deem necessary or advisable, (C) the obtaining of any approval or other clearance from any state or federal governmental agency which the Administrator shall, in its absolute discretion, determine to be necessary or
advisable, (D) the receipt by the Company of full payment for such shares of Stock, which may be in one or more of the forms of consideration permitted under Section 4.4 hereof, and (E) the receipt of full payment of any applicable
withholding tax in accordance with Section 3.4 by the Company or its Subsidiary with respect to which the applicable withholding obligation arises. 
 4.6 Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any
shares of Stock purchasable upon the exercise of any part of the Option unless and until certificates representing such shares of Stock (which may be in book-entry form) will have been issued and recorded on the records of the Company or its
transfer agents or registrars and delivered to Participant (including through electronic delivery to a brokerage account). No adjustment will be made for a dividend or other right for which the record date is prior to the date of such issuance,
recordation and delivery, except as provided in Section 12.2 of the Plan. Except as otherwise provided herein, after such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to
such shares of Stock, including, without limitation, the right to receipt of dividends and distributions on such shares. 

  
 A-5

 ARTICLE 5. 
 OTHER PROVISIONS 
 5.1 Administration. The Administrator shall have
the power to interpret the Plan, the Grant Notice and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan, the Grant Notice and this Agreement as are consistent therewith and to interpret, amend
or revoke any such rules. All actions taken and all interpretations and determinations made by the Administrator will be final and binding upon Participant, the Company and all other interested persons. To the extent allowable pursuant to Applicable
Law, no member of the Committee or the Board will be personally liable for any action, determination or interpretation made with respect to the Plan, the Grant Notice or this Agreement. 

5.2 Whole Shares. The Option may only be exercised for whole shares of Stock. 

5.3 Option Not Transferable. Subject to Section 4.1 hereof, the Option may not be sold, pledged, assigned or transferred in
any manner other than by will or the laws of descent and distribution, unless and until the shares of Stock underlying the Option have been issued, and all restrictions applicable to such shares of Stock have lapsed. Neither the Option nor any
interest or right therein or part thereof shall be liable for the debts, contracts or engagements of Participant or his or her successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance,
assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition
thereof shall be null and void and of no effect, except to the extent that such disposition is permitted by the preceding sentence. 
 5.4 Adjustments. The Administrator may accelerate the vesting of all or a portion of the Option in such circumstances as it, in its sole discretion, may determine. In addition, upon the occurrence
of certain events relating to the Stock contemplated by Section 12.2 of the Plan (including, without limitation, an extraordinary cash dividend on such Stock), the Administrator shall make such adjustments as the Administrator deems appropriate
in the number of shares of Stock subject to the Option, the exercise price of the Option and the kind of securities that may be issued upon exercise of the Option. Participant acknowledges that the Option is subject to adjustment, modification and
termination in certain events as provided in this Agreement and Section 12.2 of the Plan. 
  
 5.5 Notices. Any notice to be given under the terms of this Agreement to the Company shall be addressed to the Company in care of the Secretary of the Company at the Company’s principal
office, and any notice to be given to Participant shall be addressed to Participant at Participant’s last address reflected on the Company’s records. By a notice given pursuant to this Section 5.5, either party may hereafter designate
a different address for notices to be given to that party. Any notice which is required to be given to Participant shall, if Participant is then deceased, be given to the person entitled to exercise the Option pursuant to Section 4.1 hereof by
written notice under this Section 5.5. Any notice shall be deemed duly given when sent via email or when sent by certified mail (return receipt requested) and deposited (with postage prepaid) in a post office or branch post office regularly
maintained by the United States Postal Service. 
 5.6 Titles. Titles are provided herein for convenience only and are
not to serve as a basis for interpretation or construction of this Agreement. 
 5.7 Governing Law. The laws of the State
of Delaware shall govern the interpretation, validity, administration, enforcement and performance of the terms of this Agreement regardless of the law that might be applied under principles of conflicts of laws. 

  
 A-6

 5.8 Conformity to Securities Laws. Participant acknowledges that the Plan, the Grant
Notice and this Agreement are intended to conform to the extent necessary with all Applicable Laws, including, without limitation, the provisions of the Securities Act and the Exchange Act and any and all regulations and rules promulgated thereunder
by the Securities and Exchange Commission and state securities laws and regulations. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the Option is granted and may be exercised, only in such a manner as to conform
to Applicable Law. To the extent permitted by Applicable Law, the Plan and this Agreement shall be deemed amended to the extent necessary to conform to Applicable Law. 
 5.9 Amendment, Suspension and Termination. To the extent permitted by the Plan, this Agreement may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from
time to time by the Administrator or the Board, provided that, except as may otherwise be provided by the Plan, no amendment, modification, suspension or termination of this Agreement shall adversely affect the Option in any material way
without the prior written consent of Participant. 
 5.10 Successors and Assigns. The Company may assign any of its
rights under this Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth in Section 5.3 and the Plan, this
Agreement shall be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 
 5.11 Limitations Applicable to Section 16 Persons. Notwithstanding any other provision of the Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the
Plan, the Option, the Grant Notice and this Agreement shall be subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the Exchange Act)
that are requirements for the application of such exemptive rule. To the extent permitted by Applicable Law, this Agreement shall be deemed amended to the extent necessary to conform to such applicable exemptive rule. 

5.12 Not a Contract of Employment. Nothing in this Agreement or in the Plan shall confer upon Participant any right to continue to
serve as an employee or other service provider of the Company or any Subsidiary or shall interfere with or restrict in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or terminate the
services of Participant at any time for any reason whatsoever, with or without cause, except to the extent expressly provided otherwise in a written agreement between the Company or a Subsidiary and Participant. 

5.13 Entire Agreement. The Plan, the Grant Notice and this Agreement (including any exhibit hereto) constitute the entire
agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof. 
 5.14 Section 409A. This Award is not intended to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code (together with any Department of
Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the date hereof, “Section 409A”). However, notwithstanding any
other provision of the Plan, the Grant Notice or this Agreement, if at any time the Administrator determines that this Award (or any portion thereof) may be subject to Section 409A, the Administrator shall have the right in its sole discretion
(without any obligation to do so or to indemnify Participant or any other person for failure to do so) to adopt such amendments to the Plan, the Grant Notice or this Agreement, or adopt other policies and procedures (including amendments, policies
and procedures with retroactive effect), or take any other actions, as the Administrator determines are necessary or appropriate for this Award either to be exempt from the application of Section 409A or to comply with the requirements of
Section 409A. 

  
 A-7

 5.15 Agreement Severable. In the event that any provision of the Grant Notice or this
Agreement is held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement. 

5.16 Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein
provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets.
Participant shall have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Option, and rights no greater than the right to receive the Stock as a general
unsecured creditor with respect to options, as and when exercised pursuant to the terms hereof. 
 5.17 Counterparts. The
Grant Notice may be executed in one or more counterparts, including by way of any electronic signature, subject to Applicable Law, each of which shall be deemed an original and all of which together shall constitute one instrument. 

5.18 Broker-Assisted Sales. In the event of any broker-assisted sale of shares of Stock in connection with the payment of
withholding taxes as provided in Section 3.4(a)(v) or Section 3.4(c) or the payment of the exercise price as provided in Section 4.4(c): (A) any shares of Stock to be sold through a broker-assisted sale will be sold on the day
the tax withholding obligation or exercise of the Option, as applicable, occurs or arises, or as soon thereafter as practicable; (B) such shares of Stock may be sold as part of a block trade with other participants in the Plan in which all
participants receive an average price; (C) Participant will be responsible for all broker’s fees and other costs of sale, and Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses
relating to any such sale; (D) to the extent the proceeds of such sale exceed the applicable tax withholding obligation or exercise price, the Company agrees to pay such excess in cash to Participant as soon as reasonably practicable;
(E) Participant acknowledges that the Company or its designee is under no obligation to arrange for such sale at any particular price, and that the proceeds of any such sale may not be sufficient to satisfy the applicable tax withholding
obligation or exercise price; and (F) in the event the proceeds of such sale are insufficient to satisfy the applicable tax withholding obligation, Participant agrees to pay immediately upon demand to the Company or its Subsidiary with respect
to which the withholding obligation arises, an amount sufficient to satisfy any remaining portion of the Company’s or the applicable Subsidiary’s withholding obligation. 

5.19 Lock-Up. The Participant shall agree, if so requested by the Company and any underwriter in connection with any public
offering of securities of the Company, not to directly or indirectly offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of or otherwise
dispose of or transfer any shares of Common Stock held by him or her for such period, not to exceed one hundred eighty (180) days following the effective date of the relevant registration statement filed under the Securities Act in connection
with such public offering, as such underwriter shall specify reasonably and in good faith. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such 180-day period.

administratively practicable following the release of any Shares from the Forfeiture Restriction, the Company shall, as applicable, either deliver to Participant the certificate or certificates representing such Shares in the Company’s
possession belonging to Participant, or, if the Shares are held in book-entry form, then the Company shall remove the notations indicating that the shares are subject to the restrictions of this Agreement. Participant (or the beneficiary or personal

Unreleased Shares shall be held by the Company until such Unreleased Shares are forfeited as provided in Section 3.1, until such Unreleased Shares are fully released from the Forfeiture Restriction as provided in Section 3.2 or until such
time as this Agreement is no longer in effect. Participant shall not retain physical custody of any certificates representing Unreleased Shares issued to Participant. Participant, by acceptance of this Award, shall be deemed to appoint, and does so
appoint, the Company and each of its authorized representatives as Participant’s attorney(s)-in-fact to effect any transfer of forfeited Unreleased Shares (and Retained Distributions, if any, paid on such forfeited Unreleased Shares) to the
Company as may be required pursuant to the Plan or this Agreement, and to execute such representations or other documents or assurances as the Company or such representatives deem necessary or advisable in connection with any such transfer. To the
extent allowable by Applicable Law, the Company, or its designee, shall not be liable for any act it may do or omit to do with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its judgment. 

(b) The Company will retain custody of all cash dividends and other distributions (“Retained Distributions”) made or
declared with respect to Unreleased Shares (and such Retained Distributions will be subject to the Forfeiture Restriction and the other terms and conditions under this Agreement that are applicable to the Shares) until such time, if ever, as the
Unreleased Shares with respect to which such Retained Distributions shall have been made, paid or declared shall have become vested pursuant to the Grant Notice. Retained Distributions that were made or declared in cash will be deemed reinvested in
notional shares of Stock such that upon release and distribution of such Retained Distributions to Participant as set forth in the immediately preceding sentence, Participant shall be entitled to receive on the date of such distribution or release
an amount of cash or the number of whole shares of Stock or a combination thereof, as determined by the Administrator, the aggregate fair value of which shall be equal to the Fair Market Value of the notional shares of Stock to which such released
Retained Distributions relate. Any Retained Distributions with respect to Unreleased Shares shall be forfeited in the event such Unreleased Shares are forfeited. 
 3.4 Rights as Stockholder. Except as otherwise provided herein, upon issuance of the Shares by the Company, Participant shall have all the rights of a stockholder with respect to said Shares,
subject to the restrictions herein, including the right to vote the Shares and to receive all dividends or other distributions paid or made with respect to the Shares.

 ARTICLE IV. 
 TAXATION AND TAX WITHHOLDING 
 4.1 Representation. Participant
represents to the Company that Participant has reviewed with his or her own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement. Participant is relying solely on
such advisors and not on any statements or representations of the Company or any of its agents. Participant is ultimately liable and responsible for all taxes owed in connection with this investment and the transactions contemplated by this
Agreement, regardless of any action the Company or any Subsidiary takes with respect to any tax withholding obligations that arise in connection with the Shares. Neither the Company nor any Subsidiary makes any representation or undertaking
regarding the treatment of any tax withholding in connection with the Shares or the Participant’s sale of shares of Stock. The Company and the Subsidiaries do not commit and are under no obligation to structure this investment or the
transactions contemplated by this Agreement to reduce or eliminate Participant’s tax liability. 
 4.2
Section 83(b) Election. If Participant makes an election under Section 83(b) of the Internal Revenue Code of 1986, as amended (the “Code”), to be taxed with respect to the Shares as of the date of transfer of the
Shares rather than as of the date or dates upon which Participant would otherwise be taxable under Section 83(a) of the Code, Participant shall deliver a copy of such election to the Company promptly upon filing such election with the Internal
Revenue Service. 
 4.3 Tax Withholding. Notwithstanding any other provision of this Agreement: 

(a) The Company and its Subsidiaries have the authority to deduct or withhold, or require Participant to remit to the Company or the
applicable Subsidiary, an amount sufficient to satisfy applicable federal, state, local and foreign taxes (including the employee portion of any FICA obligation) required by law to be withheld with respect to any taxable event arising pursuant to
this Agreement. The Company and its Subsidiaries may withhold or Participant may make such payment in one or more of the forms specified below: 
 (i) by cash or check made payable to the Company or the Subsidiary with respect to which the withholding obligation arises; 
 (ii) by the deduction of such amount from other compensation payable to Participant; 
 (iii) with respect to any withholding taxes arising in connection with the vesting of the Shares, with the consent of the Administrator, by requesting that the Company and its Subsidiaries withhold a net
number of vested Shares having a then current Fair Market Value not exceeding the amount necessary to satisfy the withholding obligation of the Company and its Subsidiaries based on the minimum applicable statutory withholding rates for federal,
state, local and foreign income tax and payroll tax purposes; 
 (iv) with respect to any withholding taxes arising in
connection with the vesting of the Shares, with the consent of the Administrator, by tendering to the Company vested shares of Stock having a then current Fair Market Value not exceeding the amount necessary to satisfy the withholding obligation of
the Company and its Subsidiaries based on the minimum applicable statutory withholding rates for federal, state, local and foreign income tax and payroll tax purposes; 

  
 A-3

 (v) with respect to any withholding taxes arising in connection with the vesting of the
Shares, through the delivery of a notice that Participant has placed a market sell order with a broker acceptable to the Company with respect to those Shares that are then becoming vested and that the broker has been directed to pay a sufficient
portion of the net proceeds of the sale to the Company or the Subsidiary with respect to which the withholding obligation arises in satisfaction of such withholding taxes; provided that payment of such proceeds is then made to the Company or the
applicable Subsidiary at such time as may be required by the Administrator, but in any event not later the settlement of such sale; or 
 (vi) in any combination of the foregoing. 
 (b) With respect to any withholding
taxes arising in connection with the Shares, in the event Participant fails to provide timely payment of all sums required pursuant to Section 4.3(a), the Company shall have the right and option, but not the obligation, to treat such failure as
an election by Participant to satisfy all or any portion of Participant’s required payment obligation pursuant to Section 4.3(a)(ii) or Section 4.3(a)(iii) above, or any combination of the foregoing as the Company may determine to be
appropriate. The Company shall not be obligated to deliver any certificate representing the Shares to Participant or his or her legal representative unless and until Participant or his or her legal representative shall have paid or otherwise
satisfied in full the amount of all federal, state, local and foreign taxes applicable with respect to the taxable income of Participant resulting from the vesting of the Shares or any other taxable event related to the Shares. 

(c) In the event any tax withholding obligation arising in connection with the Shares will be satisfied under Section 4.3(a)(iii),
then the Company may elect to instruct any brokerage firm determined acceptable to the Company for such purpose to sell on Participant’s behalf a whole number of shares of Stock from those Shares that are then becoming vested as the Company
determines to be appropriate to generate cash proceeds sufficient to satisfy the tax withholding obligation and to remit the proceeds of such sale to the Company or the Subsidiary with respect to which the withholding obligation arises.
Participant’s acceptance of this Award constitutes Participant’s instruction and authorization to the Company and such brokerage firm to complete the transactions described in this Section 4.3(c), including the transactions described
in the previous sentence, as applicable. The Company may refuse to deliver any certificate representing the Shares to Participant or his or her legal representative until the foregoing tax withholding obligations are satisfied. 

(d) Participant is ultimately liable and responsible for all taxes owed in connection with the Shares, regardless of any action the
Company or any Subsidiary takes with respect to any tax withholding obligations that arise in connection with the Shares. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding
in connection with the awarding, vesting or payment of the Shares or the subsequent sale of the Shares. The Company and the Subsidiaries do not commit and are under no obligation to structure this Award to reduce or eliminate Participant’s tax
liability. 
 ARTICLE V. 
 RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS 
 5.1 Legends. The
certificate or certificates representing the Shares, if any, shall bear the following legend (as well as any legends required by the Company’s charter and Applicable Law): 

  
 A-4

 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO FORFEITURE IN
FAVOR OF THE COMPANY AND MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF A RESTRICTED STOCK AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 

5.2 Refusal to Transfer; Stop-Transfer Notices. The Company shall not be required (a) to transfer on its books any Shares
that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (b) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such
Shares shall have been so transferred. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that,
if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 
 5.3
Removal of Legend. After such time as the Forfeiture Restriction shall have lapsed with respect to the Shares, and upon Participant’s request, a new certificate or certificates representing such Shares shall be issued without the legend
referred to in Section 5.1 and delivered to Participant. If the Shares are held in book entry form, the Company shall cause any restrictions noted on the book form to be removed. 

ARTICLE VI.

certified mail (return receipt requested) and deposited (with postage prepaid) in a post office or branch post office regularly maintained by the United States Postal Service.

conform to the extent necessary with all Applicable Law, including, without limitation, the provisions of the Securities Act and the Exchange Act, and any and all regulations and rules promulgated thereunder by the Securities and Exchange
Commission, and state securities laws and regulations. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the Shares are granted, only in such a manner as to conform to Applicable Law. To the extent permitted by
Applicable Law, the Plan and this Agreement shall be deemed amended to the extent necessary to conform to Applicable Law. 
 6.8
Amendment, Suspension and Termination. To the extent permitted by the Plan, this Agreement may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from time to time by the Administrator or the
Board, provided that, except as may otherwise be provided by the Plan, no amendment, modification, suspension or termination of this Agreement shall adversely affect the Shares in any material way without the prior written consent of
Participant.

any Subsidiary or shall interfere with or restrict in any way the rights of the Company and its Subsidiaries, which rights are hereby expressly reserved, to discharge or terminate the services of Participant at any time for any reason whatsoever,
with or without cause, except to the extent expressly provided otherwise in a written agreement between the Company or a Subsidiary and Participant. 

  
 A-6

 6.12 Entire Agreement. The Plan, the Grant Notice and this Agreement (including any
exhibit hereto) constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof. 

6.13 Section 409A. This Award is not intended to constitute “nonqualified deferred compensation” within the meaning
of Section 409A of the Code (together with any Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the date hereof,
“Section 409A”). However, notwithstanding any other provision of the Plan, the Grant Notice or this Agreement, if at any time the Administrator determines that this Award (or any portion thereof) may be subject to Section 409A,
the Administrator shall have the right in its sole discretion (without any obligation to do so or to indemnify Participant or any other person for failure to do so) to adopt such amendments to the Plan, the Grant Notice or this Agreement, or adopt
other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, as the Administrator determines are necessary or appropriate for this Award either to be exempt from the application of

 6.14 Agreement Severable. In the event that
any provision of the Grant Notice or this Agreement is held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of the Grant
Notice or this Agreement. 
 6.15 Limitation on Participant’s Rights. Participation in the Plan confers no rights or
interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of
itself, has any assets. Participant shall have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Award. 

6.16 Counterparts. The Grant Notice may be executed in one or more counterparts, including by way of any electronic signature,
subject to Applicable Law, each of which shall be deemed an original and all of which together shall constitute one instrument.

offering of securities of the Company, not to directly or indirectly offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of or otherwise
dispose of or transfer any shares of Common Stock held by him or her for such period, not to exceed one hundred eighty (180) days following the effective date of the relevant registration statement filed under the Securities Act in connection
with such public offering, as such underwriter shall specify reasonably and in good faith. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such 180-day period.

 6.18 Broker-Assisted Sales. In the event of any broker-assisted sale of shares of Stock in connection with the payment
of withholding taxes as provided in Section 4.3(a)(iii) or Section 4.3(a)(v): (A) any shares of Stock to be sold through a broker-assisted sale will be sold on the day the tax withholding obligation arises or as soon thereafter as
practicable; (B) such shares of Stock may be sold as part of a block trade with other participants in the Plan in which all participants receive an average price; (C) Participant will be responsible for all broker’s fees and other
costs of sale, and Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses relating to any such sale; (D) to the extent the proceeds of such sale exceed the applicable tax withholding
obligation, the 

  
 A-7

 
Company agrees to pay such excess in cash to Participant as soon as reasonably practicable; (E) Participant acknowledges that the Company or its designee is under no obligation to arrange
for such sale at any particular price, and that the proceeds of any such sale may not be sufficient to satisfy the applicable tax withholding obligation; and (F) in the event the proceeds of such sale are insufficient to satisfy the applicable
tax withholding obligation, Participant agrees to pay immediately upon demand to the Company or its Subsidiary with respect to which the withholding obligation arises an amount in cash sufficient to satisfy any remaining portion of the
Company’s or the applicable Subsidiary’s withholding obligation.
