9.3 Limitation on Ownership of Voting Stock

(a) General. Without the prior written consent of Echelon, as authorized by resolution of a Designated Majority of the Board of Directors of Echelon, ENEL shall not (and ENEL shall not permit any other company of the ENEL Group to) acquire, directly or indirectly, beneficial ownership of any Voting Stock, any securities convertible into or exchangeable for Voting Stock or any other right to acquire Voting Stock (except, in any case, as provided herein or by way of stock dividends or other distributions or offerings by Echelon to holders of Voting Stock generally in accordance with their pro rata share ownership) or authorize or make a tender, exchange or other offer for, or enter into any agreement to effect any of the foregoing, without the prior written consent of Echelon, if the effect of such acquisition or offer would be to increase the Voting Power of all Voting Stock then beneficially owned by the ENEL Group or which it has a right to acquire to more than 10.0% of the Total Voting Power.

-24-

Notwithstanding the foregoing, if the Voting Power beneficially owned by the ENEL Group increases to a percentage in excess of the percentage specified in the preceding paragraphs solely as a result of a recapitalization, effected by Echelon or a repurchase of shares effected by Echelon, then the ENEL Group shall be permitted to continue to hold such securities and shall not be required to sell any securities of the ENEL Group to reduce the Voting Power held by the ENEL Group; provided further, that the ENEL Group shall be prohibited from acquiring any additional Voting Power of the ENEL Group so long as its beneficial ownership exceeds the limits set forth above (except as otherwise permitted by this Section 9.3).

If, subject to Section 9.6, any member of the ENEL Group shall at any time sell or otherwise transfer its beneficial ownership of any shares of Voting Stock, then the maximum percentage of the Total Voting Power which the ENEL Group is entitled to beneficially own shall be reduced to the greater of (A) the percentage of the Total Voting Power beneficially owned by the ENEL Group immediately following such sale or transfer, or (B) the percentage of Total Voting Power the ENEL group is entitled to hold pursuant to this Section 9.3(a).

(b) Tender Offers. ENEL may acquire Voting Stock without regard to the limitations set forth in Section 9.3(a) if a tender or exchange offer is made (as evidenced by the filing with the Commission of a Schedule TO and/or Registration Statement on Form S-4 or F-4 or any successor schedule or form promulgated or adopted for such purpose by the Commission) (a “Tender Offer”) and the actual dissemination of tender offer materials to security holders of Echelon) by another Person or Group to purchase or exchange for cash or other consideration any Voting Stock, which Tender Offer, if successful, would result in such Person or Group owning or having the right to acquire shares of Voting Stock with aggregate Voting Power representing at least forty percent (40%) of the Total Voting Power of Echelon then in effect. If a Tender Offer releases ENEL from the limitations set forth in this Section 9.3, and such Tender Offer subsequently expires, is enjoined or terminated prior to any purchases thereunder or is otherwise withdrawn, or is completed but does not result in the Person or Group making the Tender Offer acquiring forty percent (40%) or more of the Total Voting Power of Echelon, then the limitations of this Section 9.3 shall be reimposed, except that ENEL shall not be obligated to dispose of any Voting Stock acquired during the pendency of such Tender Offer in accordance with this Section 9.3(b).

9.4 Agreement with Respect to Voting of Stock.

(a) Agreement to Vote Shares. ENEL shall take such action as may be required so that all shares of Voting Stock owned by the ENEL Group are voted for the slate of nominees recommended by Echelon’s board of Directors to stockholders for the election as directors (which slate shall include the ENEL nominee as provided in section 9.2), including without limitation to be present, in person or by proxy, at all meetings of stockholders of Echelon voting for the election of directors.

-25-

ENEL shall use its best efforts to cause the companies in the ENEL Group that own shares of Voting Stock to be present, in person or by proxy, at all other meetings of stockholders of Echelon so that such shares of Voting Stock beneficially owned by the ENEL Group may be counted for the purposes of determining the presence of a quorum at such meetings.

The ENEL Group shall be entitled to vote the Voting Stock owned by it in its sole and absolute discretion (including by abstaining from voting), except that the provisions of the following paragraph shall govern voting in respect of the Agreed Voting Matters. With respect to Agreed Voting Matters to be voted on by holders of Voting Stock, ENEL shall vote, and shall use its best efforts to cause the other companies in the ENEL group to vote, at least the same percentage of the Voting Stock owned by them for or against such matter (as recommended by a Designated Majority of the Board of Directors of Echelon on such matter) as the percentage of Voting Stock held by all other stockholders of Echelon which is voted for or against such matter (as recommended by a Designated Majority of the Board of directors of Echelon such on matter). For purposes of the preceding sentence, the term “percentage of Voting Stock held by all other stockholders of Echelon” shall mean the percentage that is equal to (i) the Voting Stock (excluding Voting Stock owned by the ENEL Group) actually voted for or against such matter (as recommended by a Designated Majority of the Board of Directors of Echelon on such matters) divided by (ii) the total Voting Stock (excluding the Voting Stock owned by the ENEL Group) actually present and voting on such matter. ENEL shall notify Echelon in writing as soon as reasonably practicable after receiving notice of a security holder proposal if it believes that clauses (a) or (b) in the definition of the term “Agreed Voting Matter” contained in Section 9.1 hereof are applicable.

Notwithstanding anything in this Section 9.4 to the contrary, in the event that the stockholders of Echelon shall approve a Merger which is contemplated to be accounted for as a pooling of interests, the ENEL Group shall not exercise any dissenters’ rights or appraisal rights available under applicable law if Echelon previously notifies it in writing that such exercise would prevent or impair such pooling of interests treatment.

(b) Agreement Not to Place Shares in Voting Trust. The ENEL Group shall not deposit any shares of voting Stock in a voting trust, or except as otherwise provided herein, subject any voting Stock to any arrangement or agreement with respect to the voting of such Voting Stock.

(c) Solicitation of Proxies. The ENEL Group shall not without the prior written consent of Echelon solicit proxies with respect to any Voting Stock or become a “participant” in any “election contest,” as such terms are used in Rule 14a-11 of Regulation 14A under the Exchange Act relating to the election of directors of Echelon.

9.5 No participation in a Group. The ENEL Group shall not join a partnership, limited partnership, syndicate, or otherwise act in concert with any third person, for the purpose of acquiring, holding, disposing or voting of Voting Stock except as otherwise contemplated by this Agreement with respect to permissible sales of its Voting Stock or except as Echelon may approve in writing.

-26-

9.6 Restrictions on Transfer of Securities. Until the Transfer Restriction Expiration Date, ENEL shall not, and shall not permit any other company in the ENEL Group to, directly or indirectly, sell or transfer any of the shares except (i) to Echelon or in any Person or Group approved by Echelon; or (ii) to ENEL or any other company in the ENEL Group that agrees to accept such Shares subject to the restrictions set forth in this Section 9; or (iii) pursuant to a transaction involving the merger, sale, reorganization or change in Control of Echelon as approved by a Designated Majority of the Board of Directors of Echelon; or (iv) in response to (A) an offer to purchase or exchange for cash or other consideration any Voting Stock (1) which is made by or on behalf of Echelon or (2) which is made by another person or Group and is not opposed by a Designated Majority of the Board of directors of Echelon within the time the Board is required, pursuant to regulations under the Exchange Act, to advise Echelon’s stockholders of the Board’s position on such offer, or (B) subject to Echelon’s right of first refusal as set forth in Section 9.7, any other Tender Offer, which, if successful, would result in such person or Group owning or having the right to acquire shares of the Total Voting Stock with aggregate Voting Power representing at least forty percent (40%) of the Total Voting Power of Echelon then in effect. In the event that the stockholders of Echelon shall approve a Merger which is contemplated to be accounted for as a pooling of interests, the ENEL Group shall not sell or transfer any of the Shares in such a manner, in such an amount, or at such a time, that would prevent or impair such pooling of interests treatment, provided that Echelon gives ENEL prior written notice of the same.

For the avoidance of doubt, Echelon acknowledges and agrees that ENEL, and any other company in the ENEL Group that owns the Shares from time to time, may pursuant to clause (ii) above freely transfer such Shares (subject to applicable U.S. federal securities laws) to any company in the ENEL Group.

9.7 Right of First Refusal on Permitted Sales.

(a) Right of First Refusal on Tender Offer. Prior to the ENEL Group making any sale or exchange of Shares in response to a Tender Offer pursuant to Section 9.6(iv)(B), Echelon shall have the opportunity to purchase such Shares in the following manner:

(i)

ENEL shall give notice (the “Tender Notice”) to Echelon in writing of the intention of ENEL or any company in the ENEL group to tender such shares no later than ten (10) days prior to the latest time (as the same may be extended) by which Shares must be tendered in order to be accepted pursuant to such Offer or to qualify for any proration applicable to such Tender Offer (the “Tender Date”), specifying the amount of Shares proposed to be tendered. For purposes hereof, a Tender Offer to purchase Shares shall be deemed to be an offer at the price specified therein, without regard to any provisions thereof with respect to proration or conditions to the offeror’s obligation to purchase (assuming such conditions are not impossible to perform when the offer is made, without giving effect to Echelon’s right of first refusal).

-27-

(ii)

If the Tender Notice is given, Echelon shall have the right, exercisable by giving notice (the “Purchase Notice”) to ENEL no later than two (2) business days prior to the Tender Date, to purchase for cash all or part of the Shares specified in the Tender Notice for the price set forth in the Tender Notice (or its equivalent in cash as determined below), as the same may be increased from time to time. If Echelon exercises such right by giving such Purchase Notice, the closing of the purchase of such Shares shall take place on the date o which the Tender Offer is consummated, or such earlier time as Echelon shall agree; provided however, that Echelon’s obligation to purchase any such shares of the Shares following delivery of any Purchase Notice shall be contingent on consummation of the Tender Offer referred to in the corresponding Tender Notice. As a condition of the effectiveness of any exercise by Echelon of its rights to purchase under this Section 9.7, at the time Echelon delivery a Purchase Notice, it shall have provided for the payment in full to ENEL of the purchase price for the shares to be purchased by Echelon, by an escrow of funds, letter of credit facility, bank guarantee or similar arrangement reasonably acceptable to ENEL. If the purchase price specified in the Tender Offer includes any property other than cash, the cash equivalent of such property for purposes of determining the amount to be provided for and paid by Echelon pursuant to the foregoing, shall be determined by an investment banking firm mutually agreed to by Echelon and ENEL. Upon exercise of the right of first refusal (including provision for payment as described above), Echelon and ENEL shall be legally obligated to consummate the purchase contemplated thereby and shall use their best efforts to secure any approvals required in connection therewith, subject only to consummation of the Tender Offer referred to in the corresponding Tender Notice.

(iii)

If Echelon (including any assignees) does not exercise such right by giving a Purchase Notice or fails to complete the purchase, then ENEL or the ENEL Group shall be free to accept the Tender Offer. ENEL may not tender any shares pursuant to such tender offer unless ENEL has complied fully with the provisions of this Section 9.7 and Echelon (including any assignee) has failed to exercise its right of first refusal.

(b) Assignment of Rights of First Refusal. Echelon shall be entitled, as its option, to assign its rights of first refusal under this Section 9.7 (in whole or in part as to any instance or instances in which the right shall arise) to any other Person or Group, at any time (in the case of any incidence of the right of first refusal) prior to the closing of the purchase of securities pursuant to the exercise of such right of first refusal.

9.8 Repurchase Right in the Event of Change of Control of ENEL. In the event of a Change in Control of ENEL, Echelon shall have the right, by written notice to ENEL or its successor corporation not more than twenty (20) days following the effective date of such Change in Control to repurchase all the Shares, if any, beneficially owned by the ENEL group. The closing of any such repurchase and repayment shall be effected not less than sixty (60) days following the date of the written notice of election to repurchase by Echelon. The price at which such securities shall be repurchased in any such repurchase shall be the average of the Closing Price of such securities over the ten trading days immediately preceding the date of Echelon’s written notice to repurchase such securities.

-28-

9.9 Repurchase with Respect to the ENEL Group. Prior to voluntarily relinquishing control of any computer in the ENEL Group, ENEL shall use its best efforts to purchase or to cause another company in the ENEL Group to purchase the Shares then held by such company.

9.10 Termination of Certain Provisions. The covenants of ENEL and the rights of Echelon set forth in Sections 9.3, 9.4, 9.5, 9.7, 9.8 9.9 and 9.11 shall terminate upon the first to occur of the following event; (a) at such time as any Person or Group shall acquire forty percent (40%) of the Total Voting Power (other than any person or persons currently holding, individually or in the aggregate, such amount of total Voting Power) and (b) the date that is the fifth anniversary of the Closing Date. In addition, if a Tender Offer is made which meets the criteria specified in Section 9.3(b) hereof, then the covenants specified in Section 9.3, 9.4 and 9.5 shall terminate during the pendency of such Tender Offer or proposed acquisition; provided, however, that (i) such covenants shall take effect again upon Echelon’s delivery to ENEL of Echelon’s notice of exercise of its right of first refusal pursuant to Section 9.7(b) and (ii) such covenants shall take effect again if and when such Tender Offer subsequently expires, is enjoined or terminated prior to any purchases thereunder or is otherwise withdrawn, or is completed but does not result in the Person or Group making the Tender Offer acquiring forty percent (40%) or more of the Total Voting Power of Echelon, except that the ENEL Group shall not be obligated to dispose of any Voting Stock acquired in accordance with Section 9.3(b) during the pendency of such Tender Offer.

9.11 Right of First Refusal on Additional Shares. Echelon hereby grants to the ENEL Group the right of first refusal to purchase a pro rata share of New Securities (as defined in this Section 9.11) which Echelon may, from time to time, propose to sell and issue. The ENEL Group’s pro rata share for purposes of this right of first refusal is the ratio of the number of shares of Common Stock owned by the ENEL Group immediately prior to the issuance of New Securities to the total number of shares of Common Stock outstanding immediately prior to the issuance of New Securities. This right of first refusal shall be subject to the following provisions:

(a) “New Securities” shall mean any capital stock (including Common Stock and/or Preferred Stock) of Echelon whether now authorized or not, and rights, options or warrants to purchase capital stock, and securities of any type whatsoever that are, or may become, convertible into capital stock; provided however that the term “New Securities” does not include (i) securities purchased under this Agreement; (ii) securities issued pursuant to the acquisition of another business entity or business segment of any such entity by Echelon by merger, purchase of substantially all of the assets or other reorganization whereby Echelon will own not less than a majority of the voting power of such business entity or business segment of any such entity; (iii) any borrowings, direct or indirect, from financial institutions or other persons by Echelon, whether or not presently authorized, including any type of loan or payment evidenced by any type of debt instrument, provided such borrowings do not have any equity features including warrants, options or other rights to purchase capital stock and are not convertible into capital stock of Echelon; (iv) securities issued pursuant to the exercise of the 344,189 Series E warrants outstanding as of the date hereof; (v) securities issued to employees, consultants, officers, or directors of Echelon pursuant to any stock option, stock purchase or stock bonus plan, agreement or arrangement approved by the Board of Directors; (vi) securities issued to vendors or customers or to other persons in similar commercial situations with Echelon if such issuance is approved by the Board of Directors; (vii) securities issued in connections with obtaining lease financing, whether issued to a lessor, guarantor or other person; (viii) securities issued in connection with any stock split, stock dividend or recapitalization of Echelon; (ix) securities issued and sold in an underwritten offering pursuant to a registration statement filed with, and declared effective by, the SEC; (x) non-convertible Preferred Stock issued in connection with a rights plan approved by Echelon’s Board of Directors or in response to an unsolicited bid for Echelon, in each case pursuant to the authority of Article IV of Echelon’s Certificate of Incorporation; and (xi) any right, option or warrant to acquire any security convertible into the securities excluded from the definition of New Securities pursuant to subsections (i) through (x) above.

-29-

(b) In the event Echelon proposes to undertake an issuance of New Securities, it shall given ENEL prior written notice of its intention, describing the type of New Securities, and their price and the general terms upon which Echelon proposes to issue the same. The ENEL Group shall have twenty (20) business days after any such notice is effective to agree to purchase up to its pro rata share of such New Securities for the price and upon the terms specified in the notice by giving written notice to Echelon and stating therein the quantity of New Securities to be purchased.

(c) In the event the ENEL Group fails to exercise fully the right of first refusal within said twenty (20) business-day period, Echelon shall have one hundred twenty (120) days thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within one hundred twenty (120) days from the date of said agreement) to sell the New Securities in respect of which the ENEL Group’s right of first refusal was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in Echelon’s notice to ENEL pursuant to this Section 9.11. In the event Echelon has not sold within said 120-day period or entered into an agreement to sell the New Securities within said 120-day period (or sold and issued New Securities in accordance with the foregoing within one hundred twenty (120) days from the date of said agreement), Echelon shall not thereafter issue or sell any New Securities, without first again offering such securities to the ENEL group in the manner provided herein.

9.12 Further Assurances. Echelon shall use reasonable best efforts to cause the conditions in Section 7.9 and 7.10 to be satisfied as soon as practicable.
