ECHELON CORPORATION 

2016 INDUCEMENT EQUITY INCENTIVE PLAN 

STOCK OPTION AGREEMENT 

By executing the Grant Acceptance process and using the services on this Morgan Stanley Smith Barney Benefit Access® website, you, the Participant (“Participant”) and Echelon Corporation (the “Company”) agree that this Award is granted under and governed by the terms and conditions of
Company’s 2016 Inducement Equity Incentive Plan (the “Plan”) and the Terms and Conditions of the Stock Option Agreement (the “Option Agreement”), which may be amended or modified from time to time. Participant has reviewed
the Plan and this Option Agreement in its entirety, has had an opportunity to obtain the advice of counsel prior to accepting this Award and fully understands provisions of the Plan and this Option Agreement. Participant hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the Administrator upon any questions relating to the Plan and this Option Agreement. Participant further agrees to promptly notify the Company upon any change in Participant’s
residence address. PLEASE BE SURE TO READ ALL OF THE PROVISIONS FOR YOUR COUNTRY (IF ANY) IN APPENDIX A THAT CONTAINS SPECIAL TERMS AND CONDITIONS OF THIS AWARD APPLICABLE TO YOU. 

 
  

The Company hereby grants you, the Participant, a stock option (the “Option”) under the Plan, to exercise in exchange for a payment from the Company
pursuant to this Option Agreement. However, as provided in the Option Agreement, this Option may expire earlier than the Expiration Date. 
 Unless
otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Option Agreement.

 EXHIBIT A 

TERMS AND CONDITIONS OF THE STOCK OPTION AGREEMENT 

1. Grant of Option. The Company hereby grants to the Participant named in the Grant Summary 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 in this Option Agreement and the Plan, which is incorporated herein by
reference. Subject to Section 18(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 will prevail. 

2. Vesting Schedule. Except as provided in Section 4 [or as set forth on Schedule
1]1, the Option awarded by this Option Agreement will vest in accordance with the following schedule: twenty-five (25%) of the Shares subject to the Option shall vest on each annual anniversary of
the Vesting Commencement Date, subject to Participant continuing to be a Service Provider through each such date. 
 Shares scheduled to
vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in accordance with any of the provisions of this Option Agreement, unless Participant will have been continuously a Service Provider from the date of
grant until the date such vesting occurs. 
 Notwithstanding anything in this Section 2 to the contrary, and except as otherwise provided by
the Administrator, vesting of the Option will be suspended during any unpaid leave of absence other than military leave and will resume on the date Participant 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. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the Option at any
time, subject to the terms of the Plan. If so accelerated, such Option (or the portion thereof) will be considered as having vested as of the date specified by the Administrator. 

3. Termination Period. This Option will be exercisable for thirty (30) days after Participant ceases to be a Service Provider,
unless such termination is due to Participant’s death or Disability, in which case this Option will be exercisable for twelve (12) months after Participant ceases to be a Service Provider. Notwithstanding the foregoing sentence, in no
event may this Option be exercised after the Term/Expiration Date as provided above and may be subject to earlier termination as provided in Section 13 of the Plan. 

4. Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser
portion of the balance, of the unvested Option at any time, subject to the terms of the Plan. If so accelerated, such Option will be considered as having vested as of the date specified by the Administrator.

 5. Exercise of Option. 

(a) Right to Exercise. This Option may be exercised only within the term set out in Section 2, and may be exercised during such
term only in accordance with the Plan and the terms of this Option Agreement. 
 (b) Method of Exercise. This Option is
exercisable by delivery of an exercise notice, in the form attached as Exhibit B (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which will 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 Company pursuant to the provisions of the Plan. The
Exercise Notice will be completed by Participant and delivered to the Company. The Exercise Notice will be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares together with any applicable tax withholding. This Option
will be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 

6. Method of Payment. Payment of the aggregate Exercise Price will be by any of the following, or a combination thereof, at the
election of Participant: 
 (a) cash; 

(b) check; 
 (c) consideration
received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 
 (d) surrender of
other Shares which have a fair market value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares, provided that accepting such Shares, in the sole discretion of the Administrator, will not result in any adverse
accounting consequences to the Company. 
 7. Tax Obligations. 

(a) Tax-Related Items. Participant acknowledges that, regardless of any action taken by the Company or, if different,
Participant’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 Participant’s participation in the
Plan and legally applicable to Participant (“Tax-Related Items”), is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer. Participant 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
Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if Participant 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, Participant 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, Participant agrees to make
adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. 
 Finally, Participant 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 Participant’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 Participant fails to comply with his or her obligations in connection with the Tax-Related Items. 

(b) Tax Withholding. When the Option is exercised, Participant generally will recognize immediate U.S. taxable income if
Participant is a U.S. taxpayer. If Participant is a non-U.S. taxpayer, Participant will be subject to applicable taxes in his or her jurisdiction. Pursuant to such procedures as the Administrator may specify from time to time, the Company and/or
Service Recipient shall withhold the minimum amount required to be withheld for the payment of Tax Obligations or a greater amount if that amount would not trigger adverse financial accounting consequences. The Administrator, in its sole discretion
and pursuant to such procedures as it may specify from time to time, may permit Participant to satisfy such Tax Obligations, in whole or in part (without limitation), if permissible by applicable local law, by (i) paying cash,
(ii) electing to have the Company withhold otherwise deliverable Shares having a fair market value equal to the amount of such Tax Obligations, (iii) withholding the amount of such Tax Obligations from Participant’s wages or other
cash compensation paid to Participant by the company and/or the Service Recipient, (iv) delivering to the Company already vested and owned Shares having a fair market value equal to such Tax Obligations, or (v) selling a sufficient number
of such Shares otherwise deliverable to Participant through such means as the Company may determine in its sole discretion (whether through a broker or otherwise) equal to the amount of the Tax Obligations. To the extent determined appropriate by
the Company in its discretion, it will have the right (but not the obligation) to satisfy any Tax Obligations by reducing the number of Shares otherwise deliverable to Participant. Further, if Participant is subject to tax in more than one
jurisdiction between the Date of Grant and a date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges and agrees that the Company and/or the Service Recipient (and/or former employer, as applicable) may be
required to withhold or account for tax in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any required Tax Obligations hereunder at the time of the Option exercise, Participant acknowledges and
agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such amounts are not delivered at the time of exercise. 

(c) Code Section 409A. To the extent Participant is or becomes a U.S. taxpayer, this subsection will apply. Under Code Section 409A, a
stock right (such as the Option) that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per share exercise price that is determined by the Internal
Revenue Service (the “IRS”) to be less than the fair market value of an underlying share on the date of grant (a “discount stock right”) may be considered “deferred compensation.” A stock right that is a “discount
stock right” may result in (i) income 

  
 - 4 - 

 
recognition by the recipient of the stock right prior to the exercise of the stock right, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest
charges. The “discount stock right” may also result in additional state income, penalty and interest tax to the recipient of the stock right. Participant 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. Participant agrees that if the IRS determines that the 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, Participant shall be solely responsible for Participant’s costs related to such a determination. 

8. 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 deliverable hereunder unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and
delivered to Participant. After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such Shares. 

9. No Guarantee of Continued Service. PARTICIPANT 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 (OR THE AFFILIATE EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER.
PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION 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 WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE AFFILIATE EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A
SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 10. Address for Notices. Any notice to be given to the Company under
the terms of this Option Agreement will be addressed to the Company, in care of its Stock Administrator at Echelon Corporation, 2901 Patrick Henry Drive, Santa Clara, CA 95054, or at such other address as the Company may hereafter designate in
writing. 
 11. 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 Participant only by Participant. 
 12. 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. 

  
 - 5 - 

 13. Additional Conditions to Issuance of Stock. If at any time the Company will
determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or foreign law, the tax code and related regulations or the consent or approval of
any governmental regulatory authority is necessary or desirable as a condition to the purchase by, or issuance of Shares to, Participant (or his or her estate) hereunder, such purchase or issuance will not occur unless and until such listing,
registration, qualification, rule compliance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. The Company will make all reasonable efforts to meet the requirements of any
such state, federal or foreign law or securities exchange and to obtain any such consent or approval of any such governmental authority or securities exchange. Assuming such compliance, for income tax purposes the Exercised Shares will be
considered transferred to Participant on the date the Option is exercised with respect to such Exercised Shares. 
 14. Plan
Governs. This Option Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Option Agreement and one or more provisions of the Plan, the provisions of the Plan will
govern. Capitalized terms used and not defined in this Option Agreement will have the meanings set forth in the Plan. 
 15.
Administrator Authority. The Administrator will have the power to interpret the Plan and this Option Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to
interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Shares subject to the Option have vested). All actions taken and all interpretations and determinations made by the Administrator in good
faith will be final and binding upon Participant, the Company and all other interested persons. No member of the Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan
or this Option Agreement. 
 16. Nature of Grant. In accepting the Option, Participant 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) Participant is voluntarily participating in the Plan;

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

(e) the Option and Shares acquired under the Plan and the income and value of same, are not part of normal or expected compensation for
purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments; 

  
 - 6 - 

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

(h) if Participant exercises the Option and acquires Shares, the value of such Shares may increase or decrease in value, even below the
Exercise Price; 
 (i) for purposes of the Option, Participant’s engagement as a Service Provider will be considered terminated as of
the date Participant is no longer actively providing services to the Company or any Parent or Subsidiary (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 Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly provided in this Option Agreement (including by reference in the Grant Summary to other arrangements
or contracts) or determined by the Administrator, (i) Participant’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., Participant’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 Participant is a Service Provider or Participant’s employment or
service agreement, if any, unless Participant is providing bona fide services during such time); and (ii) the period (if any) during which Participant may exercise the Option after such termination of Participant’s engagement as a Service
Provider will commence on the date Participant ceases to actively provide services and will not be extended by any notice period mandated under employment laws in the jurisdiction where Participant is employed or terms of Participant’s
engagement agreement, if any; the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of his or her Option grant (including whether Participant may still be considered
to be providing services while on a leave of absence); 
 (j) 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 to be exchanged, cashed out or substituted for, in connection with
any corporate transaction affecting the Shares; and 
 (k) the following provisions apply only if Participant is providing services outside
the United States: 
  

	 	(i)	the Option and the Shares subject to the Option are not part of normal or expected compensation or salary for any purpose; 

  

	 	(ii)	Participant acknowledges and agrees that none of the Company, the Service Recipient, or any Parent or Subsidiary 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; and 

 

	 	(iii)	no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from the termination of Participant’s engagement 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 Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and in consideration of the grant of the Option to
which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the Company, any Parent, any Subsidiary or the Service Recipient, waives his or her ability, if any, to bring any such claim, and
releases the Company, any Parent or Subsidiary and the Service Recipient 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, Participant 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. 

  
 - 7 - 

 17. Data Privacy. Participant hereby explicitly
and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’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 any Parent or Subsidiary for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 

Participant understands that the Company and the Employer may hold certain personal information about Participant, including, but not
limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all Options or
any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan. 

Participant understands that Data will be transferred to a stock plan service provider as may be selected by the Company in the future,
which is assisting the Company with the implementation, administration and management of the Plan. Participant understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipient’s country of
operation (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that if he or she resides outside the United States, he or she may request a list with the names and
addresses of any potential recipients of the Data by contacting his or her local human resources representative. Participant authorizes the Company and any other possible recipients which may assist the Company (presently or in the future) with
implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing

  
 - 8 - 

 
Participant’s participation in the Plan. Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in
the Plan. Participant understands that if he or she resides outside the United States, he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to 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, Participant understands that he or she is providing the consents herein on a purely voluntary basis. If
Participant does not consent, or if Participant later seeks to revoke his or her consent, his or her engagement as a Service Provider and career with the Employer will not be adversely affected; the only adverse consequence of refusing or
withdrawing Participant’s consent is that the Company would not be able to grant Participant Options or other equity awards or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her
consent may affect Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local
human resources representative. 
 18. Language. If Participant has received this Option Agreement 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. 

19. Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to Options awarded under
the Plan or future options that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such documents by electronic delivery and
agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or a third party designated by the Company. 

20. Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of
this Option Agreement. 
 21. 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. 

22. Modifications to the Option Agreement. This Option Agreement constitutes the entire understanding of the parties on the subjects
covered. Participant 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. Modifications to this Option Agreement or the Plan can
be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding anything to the contrary in the Plan or this Option Agreement, the Company reserves the right to revise this Option Agreement as
it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Section 409A of the Code or to otherwise avoid imposition of any additional tax or income recognition under Section 409A of the Code in
connection with the Option. 

  
 - 9 - 

 23. Amendment, Suspension or Termination of the Plan. By accepting this Award,
Participant expressly warrants that he or she has received an Option under the Plan, and has received, read and understood a description of the Plan. Participant understands that the Plan is discretionary in nature and may be amended, suspended
or terminated by the Company at any time. 
 24. Governing Law. This Option Agreement will be governed by the laws of
California, without giving effect to the conflict of law principles thereof. For purposes of litigating any dispute that arises under this Option or this Option Agreement, the parties hereby submit to and consent to the jurisdiction of the
State of California, and agree that such litigation will be conducted in 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 Option is
made and/or to be performed. 
 25. Country Addendum. Notwithstanding any provisions in this Option Agreement, this Option shall be
subject to any special terms and conditions set forth in the appendix (if any) to this Option Agreement for Participant’s country (the “Country Addendum”). Moreover, if Participant relocates to one of the countries included in the
Country Addendum (if any), the special terms and conditions for such country will apply to Participant, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative
reasons. The Country Addendum constitutes part of this Option Agreement. 
 26. Restrictions on Sale of Securities. The Shares issued
upon exercise of the Option under this Option Agreement will be registered under the U.S. federal securities laws and will be freely tradable upon receipt. However, Participant’s 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. 

  
 - 10 - 

 Schedule 1 

Accelerated Vesting: 
 Notwithstanding the
previous sentence, in the event that Participant experiences an “Involuntary Termination” (as defined in the Plan) within the twelve (12) month period following a “Change of Control Merger” (as defined in the Plan”),
Participant will fully vest in and have the right to exercise Participant’s then-outstanding Options, including Shares as to which otherwise would not have been vested and exercisable. Thereafter the Option will remain exercisable in accordance
with its terms.

Company’s 2016 Inducement Equity Incentive Plan (the “Plan”) and the Terms and Conditions of Performance Shares (the “Award Agreement”), which may be amended or modified from time to time. Participant has reviewed the Plan
and this Award Agreement in its entirety, has had an opportunity to obtain the advice of counsel prior to accepting this Award and fully understands provisions of the Plan and this Award Agreement. Participant hereby agrees to accept as binding,

 Unless otherwise defined herein, the terms defined in the

 EXHIBIT A 

TERMS AND CONDITIONS OF PERFORMANCE SHARE 

1. Grant. The Company hereby grants to the Participant named in the Grant Summary an Award of Performance Shares, subject to all
of the terms and conditions in this Award Agreement and the Plan, which is incorporated herein by reference. Subject to Section 18(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 Award Agreement, the terms and conditions of the Plan will prevail. 
 2. Company’s Obligation to
Pay. Each Performance Share represents the right to receive a Share on the date it vests. Unless and until the Performance Shares will have vested in the manner set forth in Section 3, Participant will have no right to payment of any such
Performance Shares. Prior to actual payment of any vested Performance Shares, such Performance Share will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. Any Performance Shares that
vest in accordance with Sections 3 or 4 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in whole Shares, subject to Participant satisfying any applicable tax withholding obligations as set forth in
Section 7. Subject to the provisions of Section 4, such vested Performance Share will be paid in Shares as soon as practicable after vesting, but in each such case within the period ending no later than the date that is two and one-half (2 1⁄2) months from the end of the Company’s tax year that includes the vesting date. 

3. Vesting Schedule. Except as provided in Section 4 [or as set forth on Schedule
1]1, and subject to Section 5, the Performance Shares awarded by this Award Agreement will vest in accordance with the vesting schedule set forth in the Grant Summary, subject to the
Participant’s continuing to be a Service Provider on each relevant vesting date. Performance Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in accordance with any of the
provisions of this Award Agreement, unless Participant will have been continuously a Service Provider from the date of grant until the date such vesting occurs. 

Notwithstanding anything in this Section 3 to the contrary, and except as otherwise provided by the Administrator or as required by Applicable
Law, vesting of the Award will be suspended during any unpaid leave of absence other than military leave and will resume on the date Participant 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. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the Award at any time, subject to
the terms of the Plan. If so accelerated, such Award (or the portion thereof) will be considered as having vested as of the date specified by the Administrator. 

4. Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser
portion of the balance, of the unvested Performance Shares at any time, subject to the terms of the Plan. If so accelerated, such Performance Shares will be considered as having vested as of the date specified by the Administrator.

 Notwithstanding anything in the Plan or this Award Agreement to the contrary, if the vesting of
the balance, or some lesser portion of the balance, of the Performance Shares is accelerated in connection with Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the
meaning of Section 409A, as determined by the Company), other than due to death, and if (x) Participant is a “specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider and (y) the
payment of such accelerated Performance Shares will result in the imposition of additional tax under Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination as a Service Provider, then the
payment of such accelerated Performance Shares will not be made until the date six (6) months and one (1) day following the date of Participant’s termination as a Service Provider, unless Participant dies following his or her termination as a
Service Provider, in which case, the Performance Shares will be paid in Shares to Participant’s estate as soon as practicable following his or her death. It is the intent of this Award Agreement to comply with the requirements of Section 409A
so that none of the Performance Shares provided under this Award Agreement or Shares issuable thereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. For purposes
of this Award Agreement, “Section 409A” means Section 409A of the Code, and any proposed, temporary or final Treasury Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to time. 

5. Forfeiture upon Termination of Status as a Service Provider. Notwithstanding any contrary provision of this Award Agreement, the
balance of the Performance Shares that have not vested as of the time of Participant’s termination as a Service Provider for any or no reason and Participant’s right to acquire any Shares hereunder will immediately terminate. The
Administrator shall have the exclusive discretion to determine when Participant is no longer a Service Provider (including whether Participant may still be considered to be providing services while on an approved leave of absence). 

6. Death of Participant. Any distribution or delivery to be made to Participant under this Award Agreement will, if Participant is
then deceased, be made to the administrator or executor of Participant’s estate or, if the Administrator permits, Participant’s designated beneficiary. Any such transferee must furnish the Company with (a) written notice of his
or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer. 

7. Tax Obligations. 
 (a)
Responsibility for Taxes. Participant acknowledges that, regardless of any action taken by the Company or, if different, Participant’s employer (the “Employer”) or Parent or Subsidiary to which Participant is providing
services (together, the Company, Employer and/or Parent or Subsidiary to which Participant is providing services, the “Service Recipient”), the ultimate liability for any tax and/or social insurance liability obligations and requirements
in connection with the Performance Shares, including, without limitation, (a) all federal, state, and local taxes (including Participant’s Federal Insurance Contributions Act (FICA) obligation) that

  
 -3- 

 
are required to be withheld by the Company or the Employer or other payment of tax-related items related to Participant’s participation in the Plan and legally applicable to Participant,
(b) Participant’s and, to the extent required by the Company (or Service Recipient), the Company’s (or Service Recipient’s) fringe benefit tax liability, if any, associated with the grant, vesting, or exercise of the Performance
Shares or sale of Shares, and (c) any other Company (or Service Recipient) taxes the responsibility for which Participant has, or has agreed to bear, with respect to the Performance Shares (or exercise thereof or issuance of Shares thereunder)
(collectively, the “Tax Obligations”), is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Service Recipient. Participant further acknowledges that the Company and/or the
Service Recipient (i) make no representations or undertakings regarding the treatment of any Tax Obligations in connection with any aspect of the Performance Shares, including, but not limited to, the grant, vesting or settlement of the
Performance Shares, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends or other distributions, and (ii) do not commit to and are under no obligation to structure the terms of the grant or any
aspect of the Performance Shares to reduce or eliminate Participant’s liability for Tax Obligations or achieve any particular tax result. Further, if Participant is subject to Tax Obligations in more than one jurisdiction between the date of
grant and the date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges that the Company and/or the Service Recipient (or former employer, as applicable) may be required to withhold or account for Tax Obligations
in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any required Tax Obligations hereunder at the time of the applicable taxable event, Participant acknowledges and agrees that the Company may
refuse to issue or deliver the Shares. 
 (b) Tax Withholding. When Shares are issued as payment for vested Performance Shares,
Participant generally will recognize immediate U.S. taxable income if Participant is a U.S. taxpayer. If Participant is a non-U.S. taxpayer, Participant will be subject to applicable taxes in his or her jurisdiction. Pursuant to such procedures as
the Administrator may specify from time to time, the Company and/or Service Recipient shall withhold the minimum amount required to be withheld for the payment of Tax Obligations or such greater amount if that amount would not trigger adverse
financial accounting consequences. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit Participant to satisfy such Tax Obligations, in whole or in part (without limitation), if
permissible by applicable local law, by (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable Shares having a fair market value equal to the amount of such Tax Obligations, (iii) withholding the amount of
such Tax Obligations from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Employer, (iv) delivering to the Company already vested and owned Shares having a fair market value equal to such Tax
Obligations, or (v) selling a sufficient number of such Shares otherwise deliverable to Participant through such means as the Company may determine in its sole discretion (whether through a broker or otherwise) equal to the amount of the Tax
Obligations. To the extent determined appropriate by the Company in its discretion, it will have the right (but not the obligation) to satisfy any Tax Obligations by reducing the number of Shares otherwise deliverable to Participant and, until
determined otherwise by the Company, this will be the method by which such Tax Obligations are satisfied. Further, if Participant is subject to tax in more than one jurisdiction between the date of grant and a date of any relevant taxable or tax
withholding event, as applicable, Participant acknowledges and agrees that the Company and/or the Service 

  
 -4- 

 
Recipient (and/or former employer, as applicable) may be required to withhold or account for tax in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the
payment of such Tax Obligations hereunder at the time any applicable Performance Shares otherwise are scheduled to vest pursuant to Sections 3 or 4, Participant will permanently forfeit such Performance Shares and any right to receive Shares
thereunder and the Performance Shares will be returned to the Company at no cost to the Company. Participant acknowledges and agrees that the Company may refuse to deliver the Shares if such Tax Obligations are not delivered at the time they are
due. 
 8. 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 deliverable hereunder unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or
registrars, and delivered to Participant. After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such
Shares. 
 9. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE PERFORMANCE SHARES
PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR EMPLOYER) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS AWARD OF PERFORMANCE SHARES OR ACQUIRING SHARES HEREUNDER.
PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AWARD 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 WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY OR EMPLOYER TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE. 
 10. Address for Notices. Any notice to be given to the Company under the terms of this Award Agreement will be
addressed to the Company, Echelon Corporation, 2901 Patrick Henry Drive, Santa Clara, CA 95054, or at such other address as the Company may hereafter designate in writing. 

11. Grant is Not Transferable. Except to the limited extent provided in Section 6, this grant and the rights and privileges
conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer,
assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby
immediately will become null and void. 
 12. Nature of Grant. In accepting the Award, Participant acknowledges, understands and
agrees that: 
 (a) the grant of the Performance Shares is voluntary and occasional and does not create any contractual or other right to
receive future grants of Performance Shares, or benefits in lieu of Performance Shares, even if Performance Shares have been granted in the past; 

  
 -5- 

 (b) all decisions with respect to future Performance Shares or other grants, if any, will be at
the sole discretion of the Company; 
 (c) Participant is voluntarily participating in the Plan; 

(d) the Performance Shares and the Shares subject to the Performance Shares are not intended to replace any pension rights or compensation;

 (e) the Performance Shares and the Shares subject to the Performance Shares, and the income and value of same, are not part of normal or
expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments; 

(f) the future value of the underlying Shares is unknown, indeterminable and cannot be predicted; 

(g) for purposes of the Performance Shares, Participant’s status as a Service Provider will be considered terminated as of the date
Participant is no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason for such termination and whether or not later to be found invalid or in breach of employment laws in the jurisdiction where
Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly provided in this Award Agreement (including by reference in the Grant Summary to other arrangements or
contracts) or determined by the Administrator, Participant’s right to vest in the Performance Shares under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., Participant’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 Participant is a Service Provider or the terms of Participant’s
employment or service agreement, if any, unless Participant is providing bona fide services during such time); the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes
of the Performance Shares grant (including whether Participant may still be considered to be providing services while on a leave of absence); 

(h) unless otherwise provided in the Plan or by the Company in its discretion, the Performance Shares and the benefits evidenced by this Award
Agreement do not create any entitlement to have the Performance Shares 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; and 
 (i) the following provisions apply only if Participant is providing services outside the United States: 

 

	 	(i)	the Performance Shares and the Shares subject to the Performance Shares are not part of normal or expected compensation or salary for any purpose; 

  
 -6- 

	 	(ii)	Participant acknowledges and agrees that none of the Company, the Employer or any Parent or Subsidiary 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 Performance Shares or of any amounts due to Participant pursuant to the settlement of the Performance Shares or the subsequent sale of any Shares acquired upon settlement; and 

 

	 	(iii)	no claim or entitlement to compensation or damages shall arise from forfeiture of the Performance Shares resulting from the termination of Participant’s status 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 Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and in consideration of the grant of
the Performance Shares to which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the Company, any Parent or Subsidiary or the Service Recipient, waives his or her ability, if any, to
bring any such claim, and releases the Company, any Parent or Subsidiary and the Service Recipient 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, Participant 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. 

13. Data Privacy. Participant hereby explicitly and unambiguously
consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in this Award Agreement and any other Performance Share grant materials by and among, as applicable, the Employer, or other
Service Recipient the Company and any Parent or Subsidiary for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 

Participant understands that the Company and the Service Recipient may hold certain personal information about Participant, including,
but not limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all
Performance Shares or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan.

 Participant understands that Data will be transferred to a stock plan service provider as may be selected by the Company in
the future, which is assisting the Company 

  
 -7- 

 
with the implementation, administration and management of the Plan. Participant understands that the recipients of the Data may be located in the United States or elsewhere, and that the
recipients’ country of operation (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that if he or she resides outside the United States, he or she may request
a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. Participant authorizes the Company, any stock plan service provider selected by the Company and any other
possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of
implementing, administering and managing his or her participation in the Plan. Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in the Plan. Participant
understands if he or she resides outside the United States, he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to 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, Participant understands that he or she is providing the consents herein on a purely voluntary basis. If Participant does not
consent, or if Participant later seeks to revoke his or her consent, his or her status as a Service Provider and career with the Service Recipient will not be adversely affected; the only adverse consequence of refusing or withdrawing
Participant’s consent is that the Company would not be able to grant Participant Performance Shares or other equity awards or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her consent
may affect Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local human
resources representative. 
 14 Language. If Participant has received this Award Agreement 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. 

15. Binding Agreement. Subject to the limitation on the transferability of this grant contained herein, this Award Agreement will
be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 
 16.
Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any state,
federal or foreign law, the tax code and related regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to Participant (or his or her estate) hereunder, such
issuance will not occur unless and until such listing, registration, qualification, rule compliance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. Where the Company
determines that the delivery of the payment of any Shares will violate federal securities laws or other applicable laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates that the delivery of Shares
will no longer cause such violation. The Company will make all 

  
 -8- 

 
reasonable efforts to meet the requirements of any such state, federal or foreign law or securities exchange and to obtain any such consent or approval of any such governmental authority or
securities exchange.
 17. Plan Governs. This Award Agreement is subject to all terms and provisions of the Plan. In the
event of a conflict between one or more provisions of this Award Agreement and one or more provisions of the Plan, the provisions of the Plan will govern. Capitalized terms used and not defined in this Award Agreement will have the meaning set
forth in the Plan. 
 18. Administrator Authority. The Administrator will have the power to interpret the Plan and this Award
Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any
Performance Shares have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. No member of
the Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or this Award Agreement. 

19. Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to Performance Shares
awarded under the Plan or future Performance Shares that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such documents by
electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or another third party designated by the Company. 

20. Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction
of this Award Agreement. 
 21. Agreement Severable. In the event that any provision in this Award 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 Award Agreement. 

22. Modifications to the Award Agreement. This Award Agreement constitutes the entire understanding of the parties on the subjects
covered. Participant expressly warrants that he or she is not accepting this Award Agreement in reliance on any promises, representations, or inducements other than those contained herein. Modifications to this Award Agreement or the Plan
can be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding anything to the contrary in the Plan or this Award Agreement, the Company reserves the right to revise this Award Agreement as
it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Section 409A in connection to this Award
of Performance Shares. 
 23. Amendment, Suspension or Termination of the Plan. By accepting this Award, Participant expressly
warrants that he or she has received an Award of Performance Shares under 

  
 -9- 

 
the Plan, and has received, read and understood a description of the Plan. Participant understands that the Plan is discretionary in nature and may be amended, suspended or terminated by the
Company at any time. 
 24. Governing Law. This Award Agreement will be governed by the laws of California without giving effect
to the conflict of law principles thereof. For purposes of litigating any dispute that arises under this Award of Performance Shares or this Award Agreement, the parties hereby submit to and consent to the jurisdiction of the State of
California, and agree that such litigation will be conducted in 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 Award of Performance
Shares is made and/or to be performed. 
 25. Country Addendum. Notwithstanding any provisions in this Award Agreement, this Award
shall be subject to any special terms and conditions set forth in the appendix (if any) to this Award Agreement for Participant’s country (the “Country Addendum”). Moreover, if Participant relocates to one of the countries included in
the Country Addendum (if any), the special terms and conditions for such country will apply to Participant, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative
reasons. The Country Addendum constitutes part of this Award Agreement. 
 26. Restrictions on Sale of Securities. The Shares issued
as payment for vested Performance Shares awarded under this Award Agreement will be registered under the U.S. federal securities laws and will be freely tradable upon receipt. However, Participant’s 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.

 Schedule 1 

Accelerated Vesting:     

Notwithstanding the previous sentence, in the event that Participant experiences an “Involuntary Termination” (as defined in the
Plan) within the twelve (12) month period following a “Change of Control Merger” (as defined in the Plan”), Participant will fully vest in and have the right to exercise Participant’s then-outstanding Options, including Shares as
to which otherwise would not have been vested and exercisable. Thereafter the Option will remain exercisable in accordance with its terms.
