 Vesting Schedule: 
 This Option may be exercised, in whole or in part, in accordance with the following schedule: 
 25% of the Shares subject to the Option shall vest on each anniversary of the date of grant subject to the Optionee continuing to be a Service Provider on such dates. 

Termination Period: 

This Option may be exercised for thirty (30) days after the Optionee ceases to be a Service Provider. Upon the death or Disability of
the Optionee, this Option may be exercised for one (1) year after the Optionee ceases to be a Service Provider. In no event shall this Option be exercised later than the Term/Expiration Date as provided above. Notwithstanding anything in this
paragraph to the contrary, and except as otherwise provided by the Administrator or as required by local law, vesting of the option shall be suspended during any unpaid leave of absence other than military leave and will resume on the date the
Employee returns to work on a regular schedule as determined by the Company; provided, however, that no vesting credit will be awarded for the time vesting has been suspended during such leave of absence, if permissible under local law. Further, and
notwithstanding the foregoing, upon the Optionee’s “Involuntary Termination” (as defined in the Plan) within twelve (12) months following a “Change of Control Merger” (as defined in the Plan), 100% of the unvested
Shares subject to the Option shall vest in full and the Optionee shall have the right to exercise the Option as to all of the then remaining Shares subject to the Option, including Shares as to which the Optionee would not otherwise be vested or
exercisable. Thereafter, the Option shall remain exercisable in accordance with its terms as determined by the Administrator. 
 II.
AGREEMENT 
 1 Grant of Option. The Company hereby grants to the Optionee named in the Grant Summary an option
(the “Option”) to purchase the number of Shares, as set forth in the Grant Summary, at the exercise price per share set forth in the Grant Summary (the “Exercise Price”), subject to the terms and conditions of the Plan, which is
incorporated herein by reference. Subject to Section 16(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Option Agreement, the terms and conditions of the Plan shall
prevail. 
 2 Exercise of Option. 
 (a) Right to Exercise. This Option is exercisable during its term in accordance with the Vesting Schedule set out in the Grant Summary and the applicable provisions of the Plan and this Option
Agreement, subject to the Optionee’s remaining a Service Provider on each vesting date. 
 (b) Method of Exercise.
This Option is exercisable by delivery of an exercise notice, in the form attached as Exhibit A (the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares in respect of which the Option is being
exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the 

  
 -2-

 
Company pursuant to the provisions of the Plan. The Exercise Notice shall be completed by the Optionee and delivered to the Chief Financial Officer of the Company. The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by such aggregate Exercise Price.

 No Shares shall be issued pursuant to the exercise of this Option unless such issuance and exercise complies with Applicable
Laws. Assuming such compliance, for income tax purposes the Exercised Shares shall be considered transferred to the Optionee on the date the Option is exercised with respect to such Exercised Shares. 

3 Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the
election of the Optionee: 
 (a) cash; or 
 (b) check; or 
 (c) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan. 
 4 Non-Transferability of Option. This Option
may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of the Optionee only by the Optionee. The terms of the Plan and this Option Agreement shall be binding
upon the executors, administrators, heirs, successors and assigns of the Optionee. 
 5 Term of Option. This Option may
be exercised only within the term set out in the Grant Summary, and may be exercised during such term only in accordance with the Plan and the terms of this Option Agreement. 
 6 Responsibility for Taxes. The Optionee acknowledges that, regardless of any action taken by the Company or, if different, the Optionee’s employer (the “Employer”), the ultimate
liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Optionee’s participation in the Plan and legally applicable to the Optionee (“Tax-Related
Items”), is and remains the Optionee’s responsibility and may exceed the amount actually withheld by the Company or the Employer. The Optionee further acknowledges that the Company and/or the Employer (i) make no representations or
undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option, including, but not limited to, the grant, vesting or exercise of the Option, the subsequent sale of Exercised Shares acquired pursuant to such
exercise and the receipt of any dividends; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate the Optionee’s liability for Tax-Related Items or
achieve any particular tax result. Further, if the Optionee is subject to Tax-Related Items in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable, the Optionee
acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. 

  
 -3-

 Prior to any relevant taxable or tax withholding event, as applicable, the Optionee agrees
to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. 
 In this
regard, the Optionee authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by means of one or a combination of the following: (i) withholding
from the Optionee’s wages or other cash compensation paid to the Optionee by the Company and/or the Employer; or (ii) withholding from proceeds of the sale of Exercised Shares acquired at exercise of the Option either through a voluntary
sale or through a mandatory sale arranged by the Company (on the Optionee’s behalf pursuant to this authorization) without further consent. The Company may withhold or account for Tax-Related Items by considering maximum applicable rates, in
which case the Optionee will receive a refund of any over-withheld amount in cash and will have no entitlement to the Common Stock equivalent. 
 Finally, the Optionee agrees to pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the
Optionee’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if the Optionee fails to comply with his or her
obligations in connection with the Tax-Related Items. 
 7 Nature of Grant. In accepting the Option, the Optionee
acknowledges, understands and agrees that: 
 (a) 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; 
 (b) all decisions with respect to future Option or other grants, if any, will be at the sole discretion of the Company; 
 (c) the Option grant and the Optionee’s participation in the Plan shall not create a right to employment or engagement as a Service Provider, or be interpreted as forming an employment or service
contract with the Company, the Employer or any Subsidiary or affiliate of the Company; 
 (d) the Optionee is voluntarily
participating in the Plan; 
 (e) the Option and any Shares acquired under the Plan are not intended to replace any pension
rights or compensation; 
 (f) 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; 

  
 -4-

 (g) the future value of the Shares underlying the Option is unknown, indeterminable, and
cannot be predicted with certainty; 
 (h) if the underlying Shares do not increase in value, the Option will have no value;

 (i) if the Optionee exercises the Option and acquires Shares, the value of such Shares may increase or decrease in value,
even below the Exercise Price; 
 (j) no claim or entitlement to compensation or damages shall arise from forfeiture of the
Option resulting from the termination of the Optionee’s relationship as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Optionee is engaged as
a Service Provider or the terms of the Optionee’s employment or service agreement, if any), and in consideration of the grant of the Option to which the Optionee is otherwise not entitled, the Optionee irrevocably agrees never to institute any
claim against the Company, any of its Subsidiaries or affiliates or the Employer, waives his or her ability, if any, to bring any such claim, and releases the Company, its Subsidiaries and affiliates and the Employer from any such claim; if,
notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, the Optionee shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all
documents necessary to request dismissal or withdrawal of such claim; 
 (k) for purposes of the Option, the Optionee’s
engagement as a Service Provider will be considered terminated as of the date the Optionee is no longer actively providing services to the Company or one of its Subsidiaries or affiliates (regardless of the reason for such termination and whether or
not later found to be invalid or in breach of employment laws in the jurisdiction where the Optionee is engaged as a Service Provider or the terms of the Optionee’s employment or service agreement, if any), and unless otherwise expressly
provided in this Option Agreement or determined by the Company, (i) the Optionee’s right to vest in the Option under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., the
Optionee’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Optionee is engaged as a Service Provider or
the terms of the Optionee’s employment or service agreement, if any); and (ii) the period (if any) during which the Optionee may exercise the Option after such termination of the Optionee’s relationship as a Service Provider will
commence on the date the Optionee cease to actively provide services and will not be extended by any notice period mandated under employment laws in the jurisdiction where the Optionee is engaged as a Service Provider or terms of the Optionee’s
employment or service agreement, if any; the Administrator shall have the exclusive discretion to determine when the Optionee is no longer actively providing services for purposes of his or her Option grant (including whether the Optionee may still
be considered to be providing services while on a leave of absence); 
 (l) unless otherwise provided in the Plan or by the
Company in its discretion, the Option and the benefits evidenced by this Option Agreement do not create any entitlement to have the Option or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed out or
substituted for, in connection with any corporate transaction affecting the shares of the Company; 

  
 -5-

 (m) the Option and the Shares subject to the Option are not part of normal or expected
compensation or salary for any purpose; and 
 (n) the Optionee acknowledges and agrees that neither the Company, the Employer
nor any Subsidiary or affiliate of the Company shall be liable for any foreign exchange rate fluctuation between the Optionee’s local currency and the United States Dollar that may affect the value of the Option or of any amounts due to the
Optionee pursuant to the exercise of the Option or the subsequent sale of any Shares acquired upon exercise. 
 8 No Advice
Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Optionee’s participation in the Plan, or the Optionee’s acquisition or sale of the underlying
Shares. The Optionee is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan. 

9 Data Privacy. The Optionee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic
or other form, of the Optionee’s personal data as described in this Option Agreement and any other Option grant materials by and among, as applicable, the Employer, the Company and its Subsidiaries and affiliates for the exclusive purpose of
implementing, administering and managing the Optionee’s participation in the Plan. 
 The Optionee
understands that the Company and the Employer may hold certain personal information about the Optionee, including, but not limited to, the Optionee’s name, home address and telephone number, date of birth, social insurance number or other
identification number, salary, nationality, job title, any shares of stock or directorships held in the Company, details of all Options or any other entitlement to shares of stock awarded, canceled, exercised, vested, unvested or outstanding in the
Optionee’s favor, for the exclusive purpose of implementing, administering and managing the Plan (“Personal Data”). 
 The Optionee understands that Personal Data will be transferred to Morgan Stanley Smith Barney or any other third parties assisting the Company with the implementation, administration and management
of the Plan. The Optionee understands that the recipients of the Personal Data may be located in the United States or elsewhere, and that the recipient’s country (e.g., the United States) may have different data privacy laws and protections
than the Optionee’s country. The Optionee understands that he or she may request a list with the names and addresses of any potential recipients of the Personal Data by contacting his or her local human resources representative. The Optionee
authorizes the Company, Morgan Stanley Smith Barney or any other third parties assisting the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Personal Data,
in electronic or other form, for the sole purposes of implementing, administering and managing the Optionee’s participation in the Plan. The Optionee understands that Personal Data will be held only as long as is necessary to implement,
administer and manage the Optionee’s participation in the Plan. The Optionee understands that he or she may, at any time, view Personal Data, request additional 

  
 -6-

 
information about the storage and processing of Personal Data, require any necessary amendments to Personal Data or refuse or withdraw the consents herein, in any case without cost, by contacting
in writing his or her local human resources representative. Further, the Optionee understands that he or she is providing the consents herein on a purely voluntary basis. If the Optionee does not consent, or if the Optionee later seeks to revoke his
or her consent, the Optionee’s employment status or service and career with the Employer will not be adversely affected; the only adverse consequence of refusing or withdrawing the Optionee’s consent is that the Company would not be able
to grant Options or other equity awards to the Optionee or administer or maintain such awards. Therefore, the Optionee understands that refusing or withdrawing his or her consent may affect the Optionee’s ability to participate in the Plan. For
more information on the consequences of the Optionee’s refusal to consent or withdrawal of consent, the Optionee understands that he or she may contact his or her local human resources representative. 

10 Address for Notices. Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company,
in care of Human Resources Department, at Echelon Corporation, 550 Meridian Avenue, San Jose, CA 95126, or at such other address as the Company may hereafter designate in writing. 

11 Changes in the Option. In the event that as a result of a stock or extraordinary cash dividend, stock split, distribution,
reclassification, recapitalization, combination of Shares or the adjustment in capital stock of the Company or otherwise, or as a result of a merger, consolidation, spin-off or other corporate transaction or event, the Option will be increased,
reduced or otherwise affected, and by virtue of any such event the Optionee will in his or her capacity as owner of unvested Shares subject to the Option which have been awarded to him or her (the “Prior Option”) be entitled to new or
additional or different shares of stock, cash or other securities or property (other than rights or warrants to purchase securities); such new or additional or different shares, cash or securities or property will thereupon be considered to be
unvested Shares and will be subject to all of the conditions and restrictions that were applicable to the Prior Option pursuant to this Option Agreement and the Plan. If the Optionee receives rights or warrants with respect to any Prior Option, such
rights or warrants may be held or exercised by the Optionee, provided that until such exercise any such rights or warrants and after such exercise any shares or other securities acquired by the exercise of such rights or warrants will be considered
to be unvested Shares and will be subject to all of the conditions and restrictions which were applicable to the Prior Option pursuant to the Plan and this Option Agreement. The Administrator in its absolute discretion at any time may accelerate the
vesting of all or any portion of such new or additional shares of stock, cash or securities, rights or warrants to purchase securities or shares or other securities acquired by the exercise of such rights or warrants. 

12 Restrictions on Sale of Securities. Subject to the provisions of paragraph 14 below, the Shares issued as payment for exercised
Options granted under this Agreement will be registered under the U.S. federal securities laws and will be freely tradable upon receipt. However, your subsequent sale of the Shares will be subject to any market blackout-period that may be imposed by
the Company and must comply with the Company’s insider trading policies, and any other applicable securities laws.

 13 Binding Agreement. Subject to the limitation on the transferability of this grant
contained herein, this Option 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 extent permissible under local law. 

14 Compliance with Law. Notwithstanding any other provision of the Plan or this Option Agreement, unless there is an available
exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to deliver any Shares issuable upon exercise of the Option prior to the completion of any registration or
qualification of the Shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or of any other governmental regulatory body,
or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. The
Employee understands that the Company is under no obligation to register or qualify the shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of
the Shares. Further, the Optionee agrees that the Administrator shall have unilateral authority to amend the Plan and this Option Agreement without the Optionee’s consent to the extent necessary to comply with securities or other laws
applicable to issuance of Shares. 
 15 Captions. Captions provided herein are for convenience only and are not to serve
as a basis for interpretation or construction of this Option Agreement. 
 16 Agreement Severable. In the event that any
provision in this Option Agreement will be 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 this Option Agreement.

 17 Entire Agreement. The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the
entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee’s interest except by means of a writing signed by the Company and the Optionee. The Optionee expressly warrants that he or she is not accepting this Option Agreement in reliance on any promises, representations, or
inducements other than those contained herein. 
 18 Amendment, Suspension or Termination of the Plan. The Employee
understands that the Plan is established voluntarily by the Company, it is discretionary in nature and may be amended, altered, suspended or terminated by the Company at any time, to the extent permitted by the Plan. 

19 Notice of Governing Law and Venue. The Option grant and this Option Agreement shall be subject to the laws, but not the choice
of law rules, of the State of California, U.S.A. For purposes of any action, lawsuit or other proceedings brought to enforce this Option Agreement, relating to it, or arising from it, the parties hereby submit to and consent to the sole

  
 -8-

 
and exclusive jurisdiction of the courts of Santa Clara County, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this
grant is made and/or to be performed. 
 20 NO GUARANTEE OF CONTINUED SERVICE. THE OPTIONEE ACKNOWLEDGES AND AGREES THAT
THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER). THE
OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE
VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH THE OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE THE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. THE DATE OF
TERMINATION OF THE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER WILL BE DETERMINED UNDER SECTION 7(k) ABOVE.

electronic delivery and agrees to participate in the Plan through an online or electronic system established and maintained by the Company or a third party designated by the Company. 

22 Language. If the Optionee has received this Option Agreement, or any other document related to the Option and/or 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. 
 23 Appendix. Notwithstanding any provisions in this Option Agreement, the Option grant shall be subject to any special terms and conditions set forth in any Appendix to this Option Agreement for
the Optionee’s country. Moreover, if the Optionee relocates to one of the countries included in the Appendix, the special terms and conditions for such country will apply to the Optionee, to the extent the Company determines that the
application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of this Option Agreement. 
 24 Imposition of Other Requirements. The Company reserves the right to impose other requirements on the Optionee’s participation in the Plan, on the Option and on any Shares acquired under the
Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require the Optionee to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing. 

25 Waiver. The Optionee acknowledges that a waiver by the Company of breach of any provision of this Option Agreement shall not
operate or be construed as a waiver of any other provision of this Option Agreement, or of any subsequent breach by the Optionee or any other Optionee.

 26 Section 409A. Under Section 409A of the U.S. Internal Revenue Code of
1986, as amended, an Option that vests after December 31, 2004, that was granted with a per share grant price that is determined by the U.S. Internal Revenue Service (the “IRS”) to be less than the fair market value of a share common
stock on the date of grant (a “discount Option”) may be considered “deferred compensation.” For Optionees who are U.S. taxpayers, an Option that is a “discount Option” may result in (i) income recognition by the
Optionee prior to the exercise of the Option, (ii) an additional twenty percent (20%) tax, and (iii) potential penalty and interest charges. The Optionee acknowledges that the Company cannot and has not guaranteed that the IRS
will agree that the per Share Exercise Price of this Option equals or exceeds the Fair Market Value of a Share on the Date of Grant in a later examination. The Optionee agrees that if the IRS determines that this Option was granted with a per Share
Exercise Price that was less than the Fair Market Value of a Share on the Date of Grant, the Optionee will be solely responsible for the Optionee’s costs related to such a determination.

This Appendix includes additional terms and conditions that govern the Option granted to the Optionee under the Plan if the Optionee resides and/or works

If the Optionee is a citizen or resident of a country other than the one in which the Optionee is currently working, is considered a resident of another

based on the securities, exchange control, and other laws in effect in the Optionee’s country as of July 2012. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Optionee not rely on the
information in this Appendix as the only source of information relating to the consequences of his or her participation in the Plan because the information may be out of date at the time the Optionee exercises the Option or sells Shares acquired
under the Plan. 
 In addition, the information contained herein is general in nature and may not apply to the Optionee’s particular
situation, and the Company is not in a position to assure the Optionee of a particular result. Accordingly, the Optionee is advised to seek appropriate professional advice as to how the relevant laws in his or her country may apply to the
Optionee’s situation. 
 Finally, if the Optionee is a citizen or resident of a country other than the one in which the Optionee is

discretion in suspending all necessary legal obligations connected with the management and administration of the Plan, it will delete Personal Data as soon as it has accomplished all the necessary legal obligations connected with the management and
administration of the Plan. 
 The Optionee understands that Personal Data processing related to the purposes specified above
shall take place under automated or nonautomated conditions, anonymously when possible, that comply with the purposes for which Personal Data is collected and with confidentiality and security provisions as set forth by applicable laws and
regulations, with specific reference to Legislative Decree no. 196/2003. 
 The processing activity, including communication, the

performance of contractual obligations related to implementation, administration and management of the Plan. The Optionee understands that, pursuant to Section 7 of the Legislative Decree no. 196/2003, the Optionee has the right to, including
but not limited to, access, delete, update, correct or terminate, for legitimate reason, the Personal Data processing. The Optionee should contact the Employer in this regard. Furthermore, the Optionee is aware that Personal Data will not be used

 Exchange Control Information 
 Exchange control reporting is required if the Optionee
transfers cash or Shares to or from Italy in excess of €10,000 or the equivalent amount in U.S. dollars. If the payment is made through an authorized broker resident in Italy, the broker will comply with the reporting obligation. In addition,
the Optionee will have exchange control reporting obligations if the Optionee has any foreign investment (including Shares) held outside Italy in excess of €10,000. The reporting must be done on the Optionee’s individual tax return.

 If the Optionee maintains a foreign bank account outside of Japan with a value exceeding ¥50 million as of December 31, the Optionee is required to report such to the Japanese authorities on

 In addition, if the Optionee pays more than ¥30,000,000 in a single transaction for the purchase of
Shares when the Optionee exercises the Option, the Optionee must file a Payment Report with the Ministry of Finance through the Bank of Japan by the 20th day of the month following the month in which the payment was made. The precise reporting
requirements vary depending on whether or not the relevant payment is made through a bank in Japan. 
 Finally, in the unlikely event that the
Optionee purchases Shares valued at more than ¥100,000,000 in a single transaction, the Optionee must file a Securities Acquisition Report with the Ministry of Finance through the Bank of Japan within 20 days of the purchase of the Shares. A
Payment Report is required independently from a Securities Acquisition Report. Therefore, if the total amount that the Optionee pays upon a one-time transaction for exercising the Option and purchasing Shares exceeds ¥100,000,000, the Optionee
must file both a Payment Report and a Securities Acquisition Report.

 NETHERLANDS

 Insider Trading Notification 

The Optionee should be aware of the Dutch insider trading rules, which may impact the sale of Shares acquired pursuant to exercise of the Option. In
particular, the Optionee may be prohibited from effecting certain transactions involving Shares during the period in which the Optionee possesses “insider information” regarding the Company. 

In accepting the Option, the Optionee acknowledges having read and understood the Insider Trading Notification and further acknowledges that it is the
Optionee’s responsibility to comply with the following Dutch insider trading rules: 
 Under Article 5:56 of the Dutch Financial Supervision
Act, anyone who has “inside information” related to an issuing company is prohibited from effectuating a transaction in securities in or from the Netherlands. “Inside information” is knowledge of a detail concerning the issuing
company to which the securities relate that is not public and which, if published, would reasonably be expected to affect the stock price, regardless of the development of the price. The insider could be any Employee of the Company or a Subsidiary
or affiliate of the Company in the Netherlands who has inside information as described herein. 
 Given the broad scope of the definition of
inside information, certain Employees of the Company working at a Subsidiary or affiliate of the Company in the Netherlands (including the Optionees participating in the Plan) may have inside information and, thus, would be prohibited from
effectuating a transaction in securities in the Netherlands at a time when the Optionee had such inside information. Please note that the Company cannot be held liable if the Optionee violates the Dutch insider trading rules. If the Optionee is
uncertain whether the insider trading rules apply to him or her, the Optionee should consult with his or her personal legal advisor.

 Responsibility for Taxes. This provision supplements paragraph 8 of the Option Agreement. 

If payment or withholding of the income tax due is not made within ninety (90) days of the event giving rise to the income tax or such other period
specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003 (the “Due Date”), the amount of any uncollected income tax shall constitute a loan owed by

  
 Page 6 of 7

 
the Optionee to the Employer, effective as of the Due Date. The Optionee agrees that the loan will bear interest at the then-current Official Rate of Her Majesty’s Revenue and Customs
(“HMRC”), it will be immediately due and repayable, and the Company and/or the Employer may recover it at any time thereafter by any of the means referred to in paragraph 6 of the Option Agreement. The Optionee authorizes the Company to
delay the issuance of Shares to the Optionee unless and until the loan is repaid in full. 
 Notwithstanding the foregoing, if the Optionee is a
director or executive officer of the Company (within the meaning of Section 13(k) of the U.S. Securities Exchange Act of 1934, as amended), the Optionee will not be eligible for such a loan to cover the income tax due. In the event that the
Optionee is a director or executive officer and the income tax is not collected from or paid by the Optionee by the Due Date, the amount of any uncollected income tax will constitute a benefit to the Optionee on which additional income tax and
national insurance contributions (“NICs”) may be payable. The Optionee 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 Employer (as applicable) the value of any employee NICs due on this additional benefit. 
 Joint Election 

As a condition of the exercise of the Option, the Optionee agrees to accept any liability for secondary Class 1 NICs (the “Employer NICs”) that
may be payable by the Company and/or the Employer in connection with the Option and any event giving rise to Tax-Related Items. Without limitation to the foregoing, the Optionee agrees to enter into a joint election with the Employer (the
“Election”) in the form approved for such Election by HMRC, and any other required consent or election required to accomplish the transfer of Employer NICs to the Optionee. The Optionee understands that the Election applies to any Option
granted to the Optionee under the Plan after the execution of the Election. The Optionee further agrees to execute such other joint elections as may be required between the Optionee and any successor to the Company and/or the Employer. 

If the Optionee does not enter into the Election prior to the exercise of the Option or any other event giving rise to Tax-Related Items, the Optionee
shall not be entitled to exercise the Option or receive any benefit in connection with the Option unless and until the Optionee enters into the Election, and no Shares or other benefit pursuant to the Option will be issued to the Optionee under the
Plan, without any liability to the Company or the Employer. 
 The Optionee further agrees that the Company and/or the Employer may collect the
Employer NICs by any of the means set forth in paragraph 8 of the Option Agreement, as supplemented above.
