APPENDIX A

TERMS AND CONDITIONS OF PERFORMANCE SHARES

Grant #_________

1. Grant. The Company hereby grants to the Employee under the Plan [            ] Performance Shares, subject to all of the terms and conditions in this Agreement and the Plan. When the Performance Shares are paid to the Employee, par value will be deemed paid by the Employee for each Performance Share by past services rendered by the Employee, and will be subject to the appropriate tax withholdings.

2. Company’s Obligation to Pay. Each Performance Share has a value equal to the Fair Market Value of a Share on the date of grant and represents the right to receive a Share on the vesting date (or such later time indicated in this Agreement). Unless and until the Performance Shares have vested in the manner set forth in paragraphs 3, 5 or 12, the Employee will have no right to payment of such Performance Shares. Prior to actual payment of any vested Performance Shares, such Performance Shares will represent an unsecured obligation.

3. Vesting Schedule/Period of Restriction.

(a) Except as otherwise provided in paragraph 5 of this Agreement, the Performance Shares awarded by this Agreement shall vest in accordance with the vesting schedule set forth in the Notice of Grant, subject to the Employee’s continuing to be a Service Provider on each relevant vesting date. Notwithstanding anything in this paragraph 3 to the contrary, and except as otherwise provided by the Administrator, vesting of the Performance Shares 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.

(b) For purposes of this Agreement, “Involuntary Termination” shall mean, without Employee’s express written consent: (i) a significant reduction of the Employee’s duties, authority or responsibilities, relative to the Employee’s duties, authority or responsibilities as in effect immediately prior to the Change of Control Merger; (ii) a material reduction in the total cash compensation of the Employee as in effect immediately prior to the Change of Control Merger; (iii) the relocation of the Employee to a facility or a location more than thirty (30) miles from the Employee’s then present location, without the Employee’s express written consent; or (iv) any purported termination of the Employee which is not effected for “Disability” or for “Cause” (each as defined in the Plan), or any purported termination for which the grounds relied upon are not valid.

4. Payment after Vesting.

(a) One Share shall be issued for each Performance Share that vests. No fractional Shares shall be issued under this Agreement.

(b) Subject to paragraph 8, any Performance Shares that vest pursuant to paragraph 3 shall be paid in Shares as soon as practicable upon or following the date of vesting (the “Vesting Date”), but, except as provided in this Agreement, in no event later than two and one-half (2 ¹/ 2) months following the applicable Vesting Date, subject to the terms and provisions of the Plan and this Agreement.

(c) Notwithstanding anything in the Plan or this Agreement to the contrary, and subject to paragraph 8, if the vesting of the balance, or some lesser portion of the balance, of the Performance Shares is accelerated in connection with the Employee’s termination as a Service Provider, such accelerated Performance Shares will not be paid out until Employee has a “separation from service” within the meaning of Section 409A, as determined by the Company. Further, if (x) Employee is subject to U.S. income tax, and (y) Employee is a “specified employee” within the meaning of Section 409A at the time of Employee’s “separation from service” within the meaning of Section 409A (as determined by the Company), other than due to death, 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 the Employee’s termination as a Service Provider (or such later date as is necessary to avoid the imposition of additional taxation under Section 409A). Notwithstanding the foregoing, any delay in payment pursuant to this paragraph 5 will cease upon the Employee’s death and such payment will be made as soon as practicable after the date of Employee’s death, subject to paragraph 8. For purposes of this Agreement, “Section 409A” means Section 409A of the Internal Revenue Code of 1986, as amended, and any proposed, temporary or final Treasury Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to time.

(d) If the vesting of all or a portion of the Performance Shares awarded under this Agreement accelerate pursuant to Section 11(c)(i) of the Plan in the event of a “Merger” (as defined in the Plan) that is not a “change in control” within the meaning of Section 409A, the timing of payment rules that apply to discretionary accelerations under paragraph 5 also shall apply. If the vesting of all or a portion of the Performance Shares awarded under this Agreement accelerate pursuant to Section 11(c)(i) of the Plan in the event of a “Merger” (as defined in the Plan) that is a “change in control” within the meaning of Section 409A, the timing of payment rules that apply under paragraph 4(b) also shall apply.

(e) It is the intent of this Agreement to comply with the requirements of Section 409A so that none of the Performance Shares provided under this 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.

5. Administrator Discretion.

(a) The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the 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.

-4-

(b) If the Administrator, in its discretion, accelerates the vesting of the balance, or some lesser portion of the balance, of the Award, the payment of such accelerated Performance Shares nevertheless shall be made at the same time or times as if such Performance Shares had vested in accordance with the vesting schedule set forth in paragraph 3, including any necessary delay in payment pursuant to the application of paragraph 4(c) (whether or not the Employee remains employed by the Company or a Parent or Subsidiary of the Company as of such date(s)). Notwithstanding the foregoing, any delay in payment pursuant to this paragraph 5 will cease upon the Employee’s death and such payment will be made as soon as practicable after the date of Employee’s death.

6. Forfeiture. Notwithstanding any contrary provision of this Agreement, the balance of the Performance Shares that have not vested pursuant to paragraphs 3, 5 or 12 at the time of the Employee’s termination as a Service Provider for any or no reason will be forfeited and automatically transferred to and reacquired by the Company at no cost to the Company. The Employee shall not be entitled to a refund of the price paid for the Performance Shares forfeited to the Company pursuant to this paragraph 6.

7. Death of Employee. Any distribution or delivery to be made to the Employee under this Agreement will, if the Employee is then deceased, be made to the administrator or executor of the Employee’s estate. Any such administrator or executor 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.

8. Withholding of Taxes. When the Shares are issued as payment for vested Performance Shares, the Employee generally will recognize immediate U.S. taxable income if the Employee is a U.S. taxpayer. If the Employee is a non-U.S. taxpayer, the Employee will be subject to applicable taxes in his or her jurisdiction. The Company will withhold a portion of the vested Performance Shares that have an aggregate market value sufficient to pay the minimum federal, state and local income, employment and any other applicable taxes required to be withheld by the Company. No fractional Shares will be withheld or issued pursuant to the grant of Performance Shares and the issuance of Shares thereunder; any additional withholding necessary for this reason will be done by the Company through the Employee’s paycheck. The Company, in its discretion, may, and with respect to its executive officers (as determined by the Company) will, withhold an amount equal to two (2) times the fair market value of a Share from the last paycheck due to the Employee prior to the vesting of the Performance Shares. In the event that the cash amounts withheld by the Company exceed the withholding taxes that are due after the automatic withholding of whole Shares, the Company will reimburse the Employee for the excess amounts. In the event the withholding requirements are not satisfied through the withholding of Shares (or, through the Employee’s paycheck, as indicated above), no payment will be made to the Employee (or his or her estate) for Performance Shares unless and until satisfactory arrangements (as determined by the Administrator) have been made by the Employee with respect to the payment of any income and other taxes which the Company determines must be withheld or collected with respect to such Performance Shares. By accepting this Award, the Employee expressly consents to the withholding of Shares and to any additional cash withholding as provided for in this paragraph 8.

9. Rights as Stockholder. Neither the Employee nor any person claiming under or through the Employee 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 (which may be in book entry form) will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to the Employee (including through electronic delivery to a brokerage account). After such issuance, recordation and delivery, the Employee 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.

10. No Effect on Employment. Subject to any employment contract with the Employee, the terms of such employment will be determined from time to time by the Company, or the Affiliate employing the Employee, as the case may be, and the Company, or the Affiliate employing the Employee, as the case may be, will have the right, which is hereby expressly reserved, to terminate or change the terms of the employment of the Employee at any time for any reason whatsoever, with or without good cause. The transactions contemplated hereunder and the vesting schedule set forth in the Notice of Grant do not constitute an express or implied promise of continued employment for any period of time.

11. 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.

12. Changes in Performance Shares. 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 Performance Shares will be increased, reduced or otherwise affected, and by virtue of any such event the Employee will in his or her capacity as owner of unvested Performance Shares which have been awarded to him or her (the “Prior Performance Shares”) 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 Performance Shares and will be subject to all of the conditions and restrictions that were applicable to the Prior Performance Shares pursuant to this Agreement and the Plan. If the Employee receives rights or warrants with respect to any Prior Performance Shares, such rights or warrants may be held or exercised by the Employee, 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 Performance Shares and will be subject to all of the conditions and restrictions which were applicable to the Prior Performance Shares pursuant to the Plan and this 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; provided, however, that the payment of such accelerated new or additional awards shall be made in accordance with the timing of payment rules under

-6-

paragraph 5(b). If the vesting of all or a portion of such new or additional award accelerates pursuant to Section 11(c)(i) of the Plan in the event of a “Merger” (as defined in the Plan) that is not a “change in control” within the meaning of Section 409A, the timing of payment rules that apply to discretionary accelerations under paragraph 5 also shall apply. If the vesting of all or a portion of the of such new or additional award accelerates pursuant to Section 11(c)(i) of the Plan in the event of a “Merger” (as defined in the Plan) that is a “change in control” within the meaning of Section 409A, the timing of payment rules that apply under paragraph 4(b) also shall apply.

Upon any attempt to sell, pledge, assign, hypothecate, transfer 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.
