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.

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.

For the avoidance of doubt, it is the intent of the parties hereto that none of the Excluded Assets shall be transferred to Buyer. The parties hereto acknowledge and agree that the Required Assets only comprise a limited and narrowly defined portion of the overall Assets and that the Excluded Assets comprise the majority of the Assets.

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.

(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.
