Exhibit 10.2

DISTRIBUTED ENERGY SYSTEMS CORP

NON-STATUTORY STOCK OPTION AGREEMENT

1. Grant of Option.

Distributed Energy Systems Corp, a Delaware corporation (the “Company”), hereby grants to [                    ] (the “Optionee”), an option, pursuant to the Company’s 2003 Stock Option Plan (the “Plan”), to purchase an aggregate of [            ] shares of Common Stock (“Common Stock”) of the Company at a price of [            ] ($            ) per share, purchasable as set forth in and subject to the terms and conditions of this option and the Plan. Except where the context otherwise requires, the term “Company” shall include the parent and all present and future subsidiaries of the Company as defined in Sections 424(e) and 424(f) of the Internal Revenue Code of 1986, as amended or replaced from time to time (the “Code”).

2. Exercise of Option and Provisions for Termination.

(a) Vesting Schedule. Except as otherwise provided in this Agreement, this option may be exercised prior to the tenth anniversary of the date of grant (the “Expiration Date”) in installments as to not more than the number of shares set forth in the table below during the respective installment periods set forth in the table below.

The right of exercise shall be cumulative so that if the option is not exercised to the maximum extent permissible during any exercise period, it shall be exercisable, in whole or in part, with respect to all shares not so purchased at any time prior to the Expiration Date or the earlier termination of this option. Notwithstanding the foregoing, in the event of the death of the Optionee while he or she is a director of the Company, the vesting of this option shall accelerate such that this option shall thereupon become fully exercisable, in whole or in part, with respect to all of the shares subject hereto not previously purchased pursuant to the provisions hereof. This option may not be exercised at any time on or after the Expiration Date.

(b) Exercise Procedure. Subject to the conditions set forth in this Agreement, this option shall be exercised by the Optionee’s delivery of written notice of exercise to the Treasurer of the Company, specifying the number of shares to be purchased and the purchase price to be paid therefor and accompanied by payment in full in accordance with Section 3. Such exercise shall be effective upon receipt by the Treasurer of the Company of such written notice together with the required payment. The Optionee may purchase less than the number of shares covered hereby, provided that no partial exercise of this option may be for any fractional share.

(c) Exercise Period Upon Death. If the Optionee dies prior to the Expiration Date, the right to exercise this option shall terminate one year following the date of death of the Optionee (but in no event after the Expiration Date). In such event, this option shall be exercisable, within the period of one year following the date of death of the Optionee (but in no event after the Expiration Date), by the person to whom this option is transferred by will or the laws of descent and distribution, provided that this option shall be exercisable only to the extent that this option was exercisable by the Optionee on the date of his or her death. Except as otherwise indicated by the context, the term “Optionee”, as used in this option, shall be deemed to include the estate of the Optionee or any person who acquires the right to exercise this option by bequest or inheritance or otherwise by reason of the death of the Optionee.

3. Payment of Purchase Price

(a) Method of Payment. Payment of the purchase price for shares purchased upon exercise of this option shall be made (i) by delivery to the Company of cash or a check to the order of the Company in an amount equal to the purchase price of such shares, (ii) subject to the consent of the Company, by delivery to the Company of shares of Common Stock of the Company then owned by the Optionee having a fair market value equal in amount to the purchase price of such shares, (iii) by any other means which the Board of Directors determines are consistent with the purpose of the Plan and with applicable laws and regulations (including, without limitation, the provisions of Rule 16b-3 under the Securities Exchange Act of 1934 and Regulation T promulgated by the Federal Reserve Board), or (iv) by any combination of such methods of payment.

(b) Valuation of Shares or Other Non-Cash Consideration Tendered in Payment of Purchase Price. For the purposes hereof, the fair market value of any share of the Company’s Common Stock or other non-cash consideration which may be delivered to the Company in exercise of this option shall be determined in good faith by the Board of Directors of the Company.

(c) Delivery of Shares Tendered in Payment of Purchase Price. If the Optionee exercises options by delivery of shares of Common Stock of the Company, the certificate or certificates representing the shares of Common Stock of the Company to be delivered shall be duly executed in blank by the Optionee or shall be accompanied by a stock power duly executed in blank suitable for purposes of transferring such shares to the Company. Fractional shares of Common Stock of the Company will not be accepted in payment of the purchase price of shares acquired upon exercise of this option.

(d) Restrictions on Use of Option Stock.

Notwithstanding the foregoing, no shares of Common Stock of the Company may be tendered in payment of the purchase price of shares purchased upon exercise of this option if the shares to be so tendered were acquired within twelve (12) months before the date of such tender, through the exercise of an option granted under the Plan or any other stock option or restricted stock plan of the Company.

4. Delivery of Shares; Compliance With Securities Laws, Etc.

(a) General. The Company shall, upon payment of the option price for the number of shares purchased and paid for, make prompt delivery of such shares to the Optionee, provided that if any law or regulation requires the Company to take any action with respect to such shares before the issuance thereof, then the date of delivery of such shares shall be extended for the period necessary to complete such action.

(b) Listing, Qualification, Etc. This option shall be subject to the requirement that if, at any time, counsel to the Company shall determine that the listing, registration or qualification of the shares subject hereto upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of non-public information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of shares hereunder, this option may not be exercised, in whole or in part, unless such listing, registration, qualification, consent or approval, disclosure or satisfaction of such other condition shall have been effected or obtained on terms acceptable to the Board of Directors. Nothing herein shall be deemed to require the Company to apply for, effect or obtain such listing, registration, qualification, or disclosure, or to satisfy such other condition.

5. Non-transferability of Option

Except as provided in paragraph (c) of Section 2, this option is personal and no rights granted hereunder may be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) nor shall any such rights be subject to execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this option or of such rights contrary to the provisions hereof, or upon the levy of any attachment or similar process upon this option or such rights, this option and such rights shall, at the election of the Company, become null and void.

6. Rights as a Shareholder

The Optionee shall have no rights as a shareholder with respect to any shares which may be purchased by exercise of this option (including, without limitation, any rights to receive dividends or non-cash distributions with respect to such shares) unless and until a certificate representing such shares is duly issued and delivered to the Optionee. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued.

7. Adjustment Provisions.

(a) General. If through, or as a result of, any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, (i) the outstanding shares of Common Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or (ii) additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, the Optionee shall, with respect to this option or any unexercised portion hereof, be entitled to the rights and benefits, and be subject to the limitations, set forth in Section 8 of the Plan.

(b) Board Authority to Make Adjustments. Any adjustments under this Section will be made by the Board of Directors, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued pursuant to his option on account of any such adjustments.

(c) Limits on Adjustments. No adjustment shall be made under this Section which would, within the meaning of any applicable provision of the Code, constitute a modification, extension or renewal of this option or a grant of additional benefits to the Optionee.

8. Mergers, Consolidation, Distributions, Liquidations, Etc.

In the event of a consolidation or merger or sale of all or substantially all of the assets of the Company in which outstanding shares of Common Stock are exchanged for securities, cash or other property of any other corporation or business entity, or in the event of a liquidation of the Company, prior to the Expiration Date or termination of this option, the Optionee shall, with respect to this option or any unexercised portion hereof, be entitled to the rights and benefits, and be subject to the limitations, set forth in Section 8 of the Plan.
