This Asset Purchase Agreement (the “Agreement”) is made as of January 8, 2013 (the “Effective Date”), by and between Danotek (assignment for the benefit of creditors), LLC, a Delaware limited liability company, in its sole and limited capacity as Assignee for the Benefit of Creditors of Danotek Motion Technologies, Inc. (the “Seller”), with principal offices located at 1100 La Avenida Street, Building A, Mountain View, California 94043, United States, and Tecogen, Inc., a Delaware corporation (the “Buyer”), with principal offices located at 45 First Avenue, Waltham, MA 02451.

A.    By resolution of the board of directors (the “Board”) of Danotek Motion Technologies, Inc., a Delaware corporation (the “Assignor”), as memorialized in the duly executed minutes, Assignor has transferred ownership of all its right, title and interest in and to tangible and intangible assets (the “Assets”) to Seller, and in so doing has also designated Seller to act, pursuant to Delaware law, as the Assignee for the Benefit of Creditors of Assignor. The General Assignment agreement (the “General Assignment”) between Assignor and Seller, as assignee, is attached hereto as Exhibit A.

B.    Seller and Buyer have identified a subset of the Assets that Buyer desires to purchase from Seller (the “Required Assets”). The Required Assets are listed in Section 1.2 below and means the design, development, and manufacturing equipment that is solely related to the 5300 line of high power density permanent magnet generators product line (“5300 PM Generator Business”). After consummation of the Closing contemplated under this Agreement, Seller will liquidate any remaining Assets that are not Required Assets (the “Remaining Assets”), and will undertake the winding down of Assignor, which shall ultimately include, but shall not be limited to, the distribution of net funds, after payment of fees and costs associated with the liquidation and winding down, to Assignor’s creditors, which are generated from the sale of the Assets.

C.     Seller desires to sell to Buyer, and Buyer desires to purchase from Seller, the Required Assets, on the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the above recitals and the mutual covenants hereinafter set forth, Buyer and Seller hereby agree as follows:

1.1    Agreement to Sell and Purchase Required Assets. Subject to the terms and conditions of this Agreement, and in reliance on the representations, warranties and covenants set forth in this Agreement, Seller agrees to sell, assign, transfer and convey to Buyer at the Closing (as defined in Section 2.2 below), and Buyer agrees to purchase and acquire from Seller at the Closing, all of Seller’s right, title and interest in and to all of the Required Assets. The Required Assets will be sold, assigned, transferred and conveyed to Buyer (subject to Section 1.3) on the Closing Date “as is” and “where is”, with no representations or warranties other than those specifically set forth below, and subject to any and all pledges, liens, licenses, rights of possession, security interests, restrictions, encumbrances, charges, title retention, conditional sale or other security arrangements of any nature whatsoever (collectively, “Encumbrances”). other than: (i) the Encumbrances to Silicon Valley Bank; (ii) the Encumbrances granted to KFT Trust, as collateral agent for KFT Trust, Khosla Ventures III, L.P., CMEA Ventures VII, L.P. and CMEA Ventures VII (Paralell), L.P. and (iii) the Encumbrances granted to Michigan Strategic Fund (clauses (i), (ii) and (iii), collectively, the “Released Encumbrances”).

1.2    Required Assets Defined. As used in this Agreement, the term “Required Assets” means, collectively, Seller’s right, title and interest in and to the assets listed in Exhibit B attached hereto, provided, however, that the Required Assets shall not, under any circumstances, include Seller’s or Assignor’s (i) cash, (ii) accounts receivable, (iii) claims or preference or fraudulent conveyance recoveries under applicable law, (iv) state or federal tax refunds, (v) insurance refunds or recoveries, (vi) utility or leasehold security deposits, and (vii) the “Excluded Assets” (defined below). Buyer shall promptly execute and deliver to Seller any and all such further assignments, endorsements and other documents as Seller may reasonably request for the purpose of effectuating the terms and conditions of this Section.

For purposes of this Agreement, the term “Excluded Assets” means any and all properties, rights, contracts, claims or other assets other than those specifically listed or described in Exhibit B. For the avoidance of doubt, Excluded Assets include (and Required Assets do not include), any and all properties, rights, contracts, claims or other assets owned by either Assignor or Seller, except for the Required Assets, including, but not limited to, any business conducted by Assignor and its subsidiaries that is not primarily engaged in the 5300 PM Generator Business, including the design, development, research, licensing, distribution, sale, support and maintenance of all products and services (including, but not limited to, 6000, 7000, 8000 and 9000 series generators, converters or motors), other than the Products.

    (a)    Title Passage. Except as otherwise provided in this Section, upon the Closing, title to all of the Required Assets shall pass to Buyer; and Seller shall make available to Buyer possession of all of the Required Assets as provided in subsection 1.3(b), and shall further, upon Buyer’s request, execute assignments, conveyances and/or bills of sale reasonably requested to convey to Buyer title to all the Required Assets, subject to the Encumbrances, in accordance with Section 1.1 of this Agreement, as well as such other instruments of conveyance as counsel for Buyer may reasonably deem necessary to effect or evidence the transfers contemplated hereby.

(b)Delivery of Required Assets. On the Closing Date (as defined in Section 2.2), Seller shall make available to Buyer possession of the Required Assets, provided however, that the expenses of retrieving, removing and transferring the Required Assets shall be borne exclusively by Buyer.

(c)Retention of Documents. As Assignee, Seller is responsible for maintaining business records during the assignment process and, among other things, will have to prepare and file final tax returns. To the extent Buyer requires business records of Assignor that Seller requires to administer the assignment estate, Buyer shall, at its own expense, arrange to obtain copies of such records from Seller.

2.1    Purchase Price. In consideration of the sale, transfer, conveyance and assignment of all the Required Assets, except for certain Electrical Test Equipment as listed under “Electrical Test Equipment – List B” in Exhibit B attached hereto, to Buyer at the Closing. Buyer shall, as of the Closing, assume only those liabilities, if any, expressly set forth as Assumed Liabilities in Section 3.1 of this Agreement and shall pay by wire transfer [****] (the “Purchase Price”) to the Seller at the Closing.

2.2    Closing. The consummation of the purchase and sale of the Required Assets contemplated hereby will take place at a closing to be held at the offices of the Assignee (the “Closing”), on January 8, 2013 (the “Closing Date”), or at such other time or date, and at such place, or by such other means of exchanging documents, as may be agreed to by the parties hereto. If the Closing does not occur on or prior to January 14, 2013, or such later date upon which Buyer and Seller may agree in writing, this Agreement shall terminate upon written notice of termination given by either party hereto that is not in default of its obligations hereunder, and thereupon this Agreement shall become null and void and no party hereto will have any further rights or obligations hereunder, except that Sections 6.1 and 7.3 shall survive such termination.

3.1    Liabilities. Buyer agrees, upon consummation of, and effective as of, the Closing, to assume those (and only those) liabilities of Seller and of Assignor expressly listed below in this Section 3.1 (collectively, the “Assumed Liabilities”): No Assumed Liabilities.

3.2    Liabilities and Obligations Not Assumed. Except as expressly set forth in Section 3.1 above, Buyer shall not assume or become obligated in any way to pay any liabilities, debts or obligations of Seller or of Assignor whatsoever, including but not limited to any liabilities or obligations now or hereafter arising from Assignor’s business activities that took place prior to the Closing or any liabilities arising out of or connected to the liquidation and winding down of Assignor’s business. All liabilities, debts and obligations of Seller and of Assignor not expressly assumed by Buyer hereunder are hereinafter referred to as the “Excluded Liabilities.”

3.3    No Obligations to Third Parties. The execution and delivery of this Agreement shall not be deemed to confer any rights upon any person or entity other than the parties hereto, or make any person or entity a third party beneficiary of this Agreement, or to obligate either party to any person or entity other than the parties to this Agreement. Assumption by Buyer of any liabilities or obligations of Seller under Section 3.1 shall in no way expand the rights or remedies of third parties against Buyer as compared to the rights and remedies such parties would have against Seller if the Closing were not consummated.
