 2.1    Grant of Option. In consideration of Participant’s past and/or continued employment
with or service to the Company or any Subsidiary and for other good and valuable consideration, effective as of the Grant Date set forth in the Grant Notice (the “Grant Date”), the Company irrevocably grants to Participant
the Option to purchase any part or all of an aggregate of the number of Shares set forth in the Grant Notice, upon the terms and conditions set forth in the Plan, this Agreement, and the Country Provisions (if applicable), subject to adjustments as

Notice, without commission or other charge; provided, however, that the exercise price per share of the Shares subject to the Option shall not be less than 100% of the Fair Market Value of a Share on the Grant Date. Notwithstanding the
foregoing, if this Option is designated as an Incentive Stock Option and Participant is a Greater Than 10% Stockholder as of the Grant Date, the exercise price per share of the Shares subject to the Option shall not be less than 110% of the Fair
Market Value of a Share on the Grant Date.

 ARTICLE III. 

PERIOD OF EXERCISABILITY 

3.1    Commencement of Exercisability. 

(a)    Subject to this Section 3.1 and Sections 3.2, 3.3, 5.11 and 5.17 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 (or any Subsidiary that is the employer of Participant) and Participant. 
 (c)    Notwithstanding
Section 3.1(a) hereof and the Grant Notice, but subject to Section 3.1(b) hereof, in the event of a Change in Control the Option shall be treated pursuant to Sections 9.2 and 9.3 of the Plan. 

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, which shall in no event be more than
ten years from the Grant Date; 
 (b)    If this Option is designated as an Incentive Stock Option and Participant, at
the time the Option was granted, was a Greater Than 10% Stockholder, the expiration of five years from the Grant Date; 

(c)    The expiration of three months from the date of Participant’s Termination of Service, unless such termination
occurs by reason of Participant’s death or Disability or Cause;

of Participant’s Termination of Service by reason of Participant’s death or Disability; or 

(e)    Participant’s Termination of Service for Cause.

(determined as of the time the Option is granted) of all Shares with respect to which Incentive Stock Options, including the Option (if applicable), are exercisable for the first time by Participant in any calendar year exceeds $100,000, the Option
and such other options shall be Nonqualified Stock Options to the extent necessary to comply with the limitations imposed by Section 422(d) of the Code. Participant further acknowledges that the rule set forth in the preceding sentence shall be
applied by taking the Option and other “incentive stock options” into account in the order in which they were granted, as determined under Section 422(d) of the Code and the Treasury Regulations thereunder. Participant also
acknowledges that an Incentive Stock Option exercised more than three months after Participant’s Termination of Employment, other than by reason of death or Disability, will be taxed as a Nonqualified Stock Option. 

  
 A-2 













 3.5    Tax Indemnity. 

(a)    Participant agrees to hold harmless, indemnify and keep indemnified the Company, any Subsidiary and
Participant’s employing company, if different, from and against any liability for or obligation to pay any Tax-Related Items that is attributable to (1) the grant or exercise of, or any benefit
derived by Participant from, the Option, (2) the acquisition by Participant of the Shares on exercise of the Option or (3) the disposal of any Shares. 

(b)    The Option cannot be exercised until Participant has made such arrangements as the Company may require for the
satisfaction of any Tax-Related Items that may arise in connection with the exercise of the Option or the acquisition of the Shares by Participant. The Company shall not be required to issue, allot or transfer
Shares until Participant has satisfied this obligation. 
 (c)    Participant hereby acknowledges that the Company
(i) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option and (ii) does not commit to and is under no obligation to
structure the terms of the grant or any aspect of any Award, including the Option, to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Furthermore,
if Participant becomes subject to tax in more than one jurisdiction between the date of grant of an Award, including the Option, and the date of any relevant taxable event, Participant acknowledges that the Company may be required to withhold or
account for Tax-Related Items in more than one jurisdiction. 
 ARTICLE IV. 

EXERCISE OF OPTION 

4.1    Person Eligible to Exercise. Except as provided in Section 5.3 hereof, during the lifetime of
Participant, only Participant may exercise the Option or any portion thereof, unless it has been disposed of pursuant to a DRO. 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 the deceased 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. 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. However, the Option shall not be exercisable with respect to fractional
Shares. 
 4.3    Manner of Exercise. The Option, or any exercisable portion thereof, may be exercised solely by
delivery to the Secretary of the Company (or any third party administrator or other person or entity designated by the Company; for the avoidance of doubt, delivery shall include electronic delivery), during regular business hours, of all of the
following prior to the time when the Option or such portion 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. The notice shall be signed by Participant or other person then entitled to exercise the Option or such portion of the Option; 

  
 A-3 













 (b)    The receipt by the Company of full payment for the Shares with
respect to which the Option or portion thereof is exercised, including payment of any applicable Tax-Related Items, which shall be made by deduction from other compensation payable to Participant or in such
other form of consideration permitted under Section 4.4 hereof that is acceptable to the Company; 
 (c)    Any
other written representations or documents as may be required in the Administrator’s sole discretion to evidence compliance with the Securities Act, the Exchange Act or any other Applicable Law; and 

(d)    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 Company 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. 

4.4    Method of Payment. Payment of the exercise price shall be by any of the following, or a combination thereof,
at the election of Participant: 
 (a)    Cash or check; 

(b)    With the consent of the Administrator, surrender of Shares (including, without limitation, Shares 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; or 
 (c)    Other legal consideration acceptable to the Administrator
(including, without limitation, through the delivery of a notice that Participant has placed a market sell order with a broker with respect to Shares 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 Company, but in any
event not later than the settlement of such sale). 
 4.5    Conditions to Issuance of Shares. The Shares
deliverable upon the exercise of the Option, or any portion thereof, may be either previously authorized but unissued Shares or issued Shares which have then been reacquired by the Company. Such Shares shall be fully paid and nonassessable. The
Company shall not be required to issue or deliver any Shares purchased upon the exercise of the Option or portion thereof prior to fulfillment of all of the conditions in Section 10.7 of the Plan. 

4.6    Participant’s Representations. If the Shares issuable hereunder have not been registered under the
Securities Act or any applicable state laws on an effective registration statement at the time of exercise, Participant shall, if required by the Company, concurrently with such exercise, make such written representations as are deemed necessary or
appropriate by the Company or its counsel. 
 4.7    Rights as Stockholder. The holder of the Option shall not
be, nor have any of the rights or privileges of, a stockholder of the Company, including, without limitation, voting rights and rights to dividends, in respect of any Shares purchasable upon the exercise of any part of the Option unless and until
such Shares shall have been issued by the Company and held of record by such holder (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall 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 Article IX of the Plan.

 ARTICLE V. 

OTHER PROVISIONS 

5.1    Administration. The Administrator shall have the power to interpret the Plan and this Agreement and to adopt
such rules for the administration, interpretation and application of the Plan 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 in

Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto.

to the person entitled to exercise his or her Option pursuant to Section 4.1 hereof by written notice under this Section 5.7. 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 (or similar non-U.S. entity).

 A-5 













 5.9    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. By entering into this Agreement, Participant
irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the courts of the State of Delaware and of the United States of America, in each case located in the State of Delaware, for any action arising out of or relating to
this Agreement and the Plan (and agrees not to commence any litigation relating thereto except in such courts), and further agrees that service of any process, summons, notice or document by U.S. registered mail to the address contained in the
records of the Company shall be effective service of process for any litigation brought against it in any such court. By entering into this Agreement, Participant irrevocably and unconditionally waives any objection to the laying of venue of any
litigation arising out of the Plan or this Agreement in the courts of the State of Delaware or the United States of America, in each case located in the State of Delaware, and further irrevocably and unconditionally waives and agrees not to plead or
claim in any such court that any such litigation brought in any such court has been brought in an inconvenient forum. By entering into this Agreement, Participant irrevocably and unconditionally waives, to the fullest extent permitted by applicable
law, any and all rights to trial by jury in connection with any litigation arising out of or relating to the Plan or this Agreement. 

5.10    Conformity to Securities Laws. Participant acknowledges that the Plan and this Agreement are intended to
conform to the extent necessary with all provisions of the Securities Act and the Exchange Act and any other Applicable Law. 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 such 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 such Applicable Law. 

5.11    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, however, 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.

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 herein set forth in Section 5.3 hereof, this Agreement shall be
binding upon Participant and his or her heirs, executors, administrators, successors and assigns. 

5.13    Notification of Disposition. If this Option is designated as an Incentive Stock Option, Participant shall
give prompt notice to the Company of any disposition or other transfer of any Shares acquired under this Agreement if such disposition or transfer is made (a) within two years from the Grant Date with respect to such Shares or (b) within
one year after the transfer of such Shares to Participant. Such notice shall specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by Participant
in such disposition or other transfer. 
 5.14    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, then the Plan, the Option 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. 

  
 A-6 













 5.15    Not a Contract of Service Relationship. Nothing in this
Agreement or in the Plan shall confer upon Participant any right to commence or continue to serve as an Employee or other Service Provider 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 by Applicable Law or in a written agreement between
the Company or a Subsidiary (as applicable) and Participant. 
 5.16    Entire Agreement. The Plan, the Grant
Notice and this Agreement (including the Country Provisions) 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, provided that the Option shall be subject to any accelerated vesting provisions in any written agreement between Participant and the Company (or any Subsidiary who is the employer of Participant) or a Company plan pursuant to which
Participant is eligible to participate, in each case, in accordance with the terms therein. 
 5.17    Section
409A. This Option 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 the Option (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 either for the Option to be exempt from the application of Section 409A or to comply with the requirements of Section 409A.

5.18    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 and its Subsidiaries 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 Shares as a general unsecured creditor with respect to the Option, as and when exercised pursuant to the terms hereof. 

5.19    Rules Particular To Specific Countries. 

(a)    Generally. Participant shall, if required by the Administrator, enter into an election with the
Company or a Subsidiary (in a form approved by the Company) under which any liability to the Company’s (or a Subsidiary’s) Tax-Related Items, including, but not limited to, National Insurance
Contributions (“NICs”) and the Fringe Benefit Tax, is transferred to and met by Participant. 

(b)    Tax Indemnity. Participant shall indemnify and keep indemnified the Company and any of its subsidiaries from
and against any Tax-Related Items. 
 5.20    Special Country Provisions for
Options Granted to Participants. This Option shall be subject to the Country Provisions, if any, for Participant’s country of residence, as set forth in the Country Provisions. If Participant relocates to one of the countries included in
the Country Provisions during the life of this Option, the special provisions for such country shall apply to Participant, to the 

  
 A-7 













 
extent the Company determines that the application of such provisions is necessary or advisable in order to comply with local law or facilitate the administration of the Plan. The Company
reserves the right to impose other requirements on this Option and the Shares purchased upon exercise of this Option, to the extent the Company determines it is necessary or advisable in order to comply with local laws or facilitate the
administration of the Plan, and to require Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

 APPENDIX 

TO 
 STOCK OPTION
AGREEMENT 
 Special Country Provisions for Options for Participants 

This Appendix includes special terms and conditions applicable to Participants in the countries below. These terms and conditions are in addition to those set
forth in the Stock Option Agreement (the “Agreement”) and the Plan, and to the extent there are any inconsistencies between these terms and conditions and those set forth in the Agreement, these terms and conditions shall
prevail. Any capitalized term used in this Appendix without definition shall have the meaning ascribed to such term in the Plan or the Agreement, as applicable. 

In accepting the Option, Participant acknowledges, understands and agrees that: 

(a)    the Plan is established voluntarily by the Company, it is discretionary in nature, and may be amended, suspended or
terminated by the Company at any time, to the extent permitted by the Plan; 
 (b)    the grant of the Option is
voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past; 

(c)    all decisions with respect to future option or other grants, if any, will be at the sole discretion of the Company;

 (d)    the Option grant and Participant’s participation in the Plan shall not create a right to employment or be
interpreted as forming an employment or service contract with the Company, or, if different, Participant’s employer, or any Subsidiary or parent or affiliate of the Company, and shall not interfere with the ability of the Company, the employer
or any Subsidiary or parent or affiliate of the Company, as applicable, to provide for a termination of Participant’s service; 

(e)    Participant is voluntarily participating in the Plan; 

(f)    the Option and any Shares acquired under the Plan are not intended to replace any pension rights or compensation;

 (g)    the Option and any Shares acquired under the Plan and the income and value of same, are not part of normal or
expected compensation for any purpose, including, without limitation, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service
payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments; 
 (e)    the
future value of the Shares underlying the Option is unknown, indeterminable, and cannot be predicted with certainty; 

(f)    if the underlying Shares do not increase in value, the Option will have no value; 

(g)    if Participant exercises the Option and acquires Shares, the value of such Shares may increase or decrease in
value, even below the exercise price; and 

  
 Appendix-1 













 (h)    neither the Company, the employer nor any parent, Subsidiary or
affiliate of the Company shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the Option or of any amounts due to Participant pursuant to the
exercise of the Option or the subsequent sale of any Shares acquired upon exercise.  
 Securities Law Notice: Unless
otherwise noted, neither the Company nor the Shares are registered with any local stock exchange or under the control of any local securities regulator outside the United States. The Agreement (of which this Appendix is a part), the Plan, and any
other communications or materials that Participant may receive regarding participation in the Plan do not constitute advertising or an offering of securities outside the United States, and the issuance of securities described in any Plan-related
documents is not intended for public offering or circulation in Participant’s jurisdiction. 
 General Provisions 

Data Privacy: Participant acknowledges and agrees to the data privacy provisions set forth in Section 11.8 of the
Plan. 
 Notifications: This Appendix also includes information relating to exchange control and other issues of which Participant should
be aware with respect to his or her participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the respective countries as of July 2021. Such laws are often complex and change frequently. As a
result, the Company strongly recommends that Participant not rely on the information herein as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the Option
is exercised or Shares acquired under the Plan are sold. In addition, the information contained in this Appendix is general in nature and may not apply to Participant’s particular situation, and the Company is not in a position to assure
Participant of any particular result. Accordingly, Participant is advised to seek appropriate professional advice as to how the relevant laws in his or her country may apply to his or her situation. Finally, Participant understands that if
Participant is a citizen or resident of a country other than the one in which he or she is currently residing or working, the information contained herein may not be applicable to Participant. 

English Language: By participating in the Plan, Participant acknowledges that Participant is proficient in the English language, or has
consulted with an advisor who is sufficiently proficient in English, so as to allow him or her to understand the terms and conditions of the Plan and the Agreement applicable to Participant’s country of residence. If Participant has received
the Agreement and the Plan applicably to his or her country of residence or any other document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the
English version will control. 
 Currency: Participant understands that, any amounts related to the Option will be denominated in U.S. dollars
and will be converted to any local currency using a prevailing exchange rate in effect at the time such conversion is performed, as determined by the Company. Participant understands and agrees that neither the Company nor any affiliate shall be
liable for any foreign exchange rate fluctuation between Participant’s local currency and the U.S. dollar that may affect the value of the Option, or of any amounts due to Participant or as a result of the subsequent sale of any Shares acquired
under the Option. 
 Foreign Asset/Account Reporting; Exchange Controls: Participant’s country of residence may have
certain foreign asset and/or account reporting or exchange control requirements which may affect his or her ability to acquire or hold Shares under the Agreement or cash received (including proceeds arising


  
 Appendix-2

 Termination Date. The
following provision supplements Article III of the Agreement: 
 For purposes of this Option, Participant’s Termination of Service is deemed to occur
(regardless of the reason for the termination and whether or not later found to be invalid or in breach of Applicable Law in the jurisdiction where Participant is rendering services or the terms of Participant’s employment or service agreement,
if any) on the date (the “Termination Date”) that is the earliest of (1) the termination date of Participant’s status as a Service Provider, (2) the date Participant receives written notice of termination of
Participant’s status as a Service Provider, or (3) the date Participant is no longer actively employed by or actively providing services to the Company or any of its Subsidiaries regardless of any notice period or period of pay in lieu of
such notice mandated under Applicable Law (including, but not limited to, statutory law, regulatory law and/or common law) in the jurisdiction where Participant is rendering service or the terms of Participant’s employment or other service
agreement, if any. The Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of this Option (including whether Participant may still be considered to be providing
services while on a leave of absence). 
 Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued
participation in the Plan during a statutory notice period, Participant acknowledges that his or her right to participate in the Plan, if any, will terminate effective as of the last day of Participant’s minimum statutory notice period, but
Participant will not earn or be entitled to pro-rata vesting if the vesting date falls after the end of Participant’s statutory notice period, nor will Participant be entitled to any compensation for lost

 Securities Law Information.
The sale or other disposal of Shares acquired under the Plan will take place only outside of Canada through the facilities of a stock exchange on which the Shares are listed. 

Foreign Asset/Account Reporting Information. Canadian residents are required to report any foreign specified property (including cash held outside of
Canada and Shares acquired under the Plan) on form T1135 (Foreign Income Verification Statement) if the total value of the foreign specified property exceeds C$100,000 at any time in the year. Options must be reported (generally, at nil cost) on
Form 1135 if the C$100,000 cost threshold is exceeded due to other foreign specified property Participant holds. When Shares are acquired, their cost generally is the adjusted cost base (“ACB”) of the Shares. The ACB would
ordinarily equal the Fair Market Value of the Shares at exercise, but if Participant owns other Shares, this ACB may have to be averaged with the ACB of the other Shares. The form T1135 must be filed with Participant’s annual tax return by
April 30 of the following year for every year during which his or her foreign property exceeds C$100,000. Participant should consult with his or her personal tax advisor to determine his or her reporting requirements.

 UNITED KINGDOM 

Terms and Conditions 
 Tax Withholding. The
following provisions supplement Section 3.5 of the Stock Option Agreement: 
 Without limitation to Section 3.5 of the Stock Option Agreement,
Participant agrees that Participant is liable for all Tax-Related Items and hereby covenants to pay all such Tax-Related Items as and when requested by the Company or
other affiliate of the Company for which Participant renders services (the “Service Recipient”) or by Her Majesty’s Revenue and Customs (“HMRC”) (or any other tax authority or any other relevant
authority). Participant also agrees to indemnify and keep indemnified the Company and the Service Recipient against any Tax-Related Items that they are required to pay or withhold or have paid or will pay to
HMRC (or any other tax authority or any other relevant authority) on Participant’s behalf. 
 Notwithstanding the foregoing, if Participant is a
director or executive officer (within the meaning of Section 13(k) of the Exchange Act), Participant understands that he or she may not be able to indemnify the Company or the Service Recipient for the amount of
Tax-Related Items not collected from or paid by Participant because the indemnification could be considered to be a loan. In this case, any income tax not collected within ninety (90) days of the end of
the U.K. tax year in which an event giving rise to the Tax-Related Items occurs may constitute a benefit to Participant on which additional income tax and employee NICs may be payable. Participant understands
that he or she will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company and/or the Service Recipient (as appropriate) for the value
of employee NICs due on this additional benefit which the Company or the Service Recipient may recover from Participant by any of the means referred to in Section 4.4 of the Stock Option Agreement.
