The funds used to purchase the shares came from the working capital of Sinotruk BVI. No borrowed funds were used to purchase the shares, other than any borrowed funds that may have been available to Sinotruk BVI for working capital purposes in the ordinary course of its business.

Item 4. Purpose of Transaction

Item 4 of this Schedule 13D is hereby amended and supplemented to add the following:

On November 30, 2017, the Issuer entered into a joint venture agreement, dated November 30, 2017 (the “Joint Venture Agreement”), with CNHTC and Sinotruk Global Village Investment Limited, a Hong Kong based limited liability company (“SGVIL”), in connection with the Stock Purchase Agreement. A copy of the Joint Venture Agreement is attached to this statement on this Schedule 13D as Exhibit 3. The joint venture (the “JV”) will be named “Sinotruk Qingdao Zhongqi New Energy Automobile Co., Ltd.” (the “JV Entity”) and will be headquartered in the city of Qingdao, Shandong province, China. The purpose of the JV was to design, produce, manufacture, market and sell commercial electric motor systems with transmission related motors in the electric vehicle market in China and to work to sell mutually developed E-axle products globally. Under the Joint Venture Agreement, the Issuer acquired a 25% equity interest in the JV with the option to increase its ownership interest to 33% beginning after the first anniversary of the agreement through the third anniversary, at a price equal to the then-market price of the JV shares. The initial total capital of the JV was $24 million, with UQM contributing $6 million. Each party was scheduled to contribute 16.7% of its capital contribution by December 31, 2017, 33.3% by June 30, 2018, and the remaining 50% by December 31, 2018, but none of these actions were completed. The proceeds of the initial capital contribution are used primarily for acquisition of manufacturing facilities and related infrastructure and employment of key personnel. The board of directors of the JV consists of five directors, with one of the directors to be nominated by the Issuer and the remaining directors nominated by CNHTC and SGVIL.

On November 6, 2017, the Issuer entered into a technology license and services agreement (the “Technology License and Services Agreement”) with the JV Entity, a limited liability company organized pursuant to the terms of the Joint Venture Agreement. A copy of the Technology License and Services Agreement is attached to this statement on Schedule 13D as Exhibit 4. Under the Technology License and Services Agreement, the Issuer granted to the JV Entity a non-transferable and exclusive license in China to manufacture the Issuer’s permanent synchronous motors and inverter controller technology for the commercial vehicle market, specifically related to the Issuer’s current PowerPhaseHD and PowerPhasePro motor and motor-controlling, transmission controller and speed shifting appliance technologies. The initial term of the Technology License and Services Agreement is seven years. The scope of the license is limited to the manufacture and sale of UQM products in China, although the parties may in the future jointly develop and sell electric motor, E-axle and integrated motor and transmission products manufactured by the JV Entity outside of China. The license grant included the right to use Issuer’s patents, copyrights, technical documentation and related knowhow related to such products as required for the manufacture and sale of these products in the commercial vehicle market in China. In addition, the Issuer will provide certain technical assistance to support the manufacture of the products for use in the commercial market in China.

The foregoing descriptions of the Joint Venture Agreement and the Technology License and Services Agreement do not purport to be complete and is qualified in their entirety by reference to the Joint Venture Agreement and the Technology License and Services Agreement, respectively, copies of which are filed as Exhibits 3 and 4, respectively, to this statement on Schedule 13D and incorporated herein by reference.

On March 5, 2018, the Issuer announced that it, along with CNHTC, have decided to withdraw their joint application to the CFIUS for the approval of the second acquisition provided for in the previously announced Stock Purchase Agreement. On May 9, 2018, the Issuer announced that CFIUS had advised the Issuer and CNHTC that it would likely not approve the second acquisition as contemplated in the Stock Purchase Agreement.

On January 16, 2019, the Issuer terminated the Stock Purchase Agreement with Sinotruk BVI and CNHTC as the Stock Purchase Agreement related to the originally contemplated second acquisition.
