Description of long-term contract for purchase of electric power        
Rongfeng will start to pay an energy saving fee from the date when the WHPG station passes the required 72-hour test run. The payment term is 20 years. For the first 10 years, Rongfeng shall pay an energy saving fee at RMB 0.582 ($0.095) per kilowatt hour (including tax) for the power generated from the system. For the second 10 years, Rongfeng shall pay an energy saving fee at RMB 0.432 ($0.071) per kWh (including tax). During the term of the contract the energy saving fee shall be adjusted at the same percentage as the change of local grid electricity price. Rongfeng and its parent company will provide guarantees to ensure Rongfeng will fulfill its obligations under the Rongfeng Agreement. Upon the completion of the term, Xi’an TCH will transfer the systems to Rongfeng at RMB 1. Rongfeng shall provide waste heat to the systems for no less than 8,000 hours per year with a temperature no less than 950°C. If these requirements are not met, the term of the Agreement will be extended accordingly. If Rongfeng wants to terminate the Agreement early, it shall provide Xi’an TCH a 60 day notice and pay the termination fee and compensation for the damages to Xi’an TCH according to the following formula: 1) if it is less than five years (including five years) into the term when Rongfeng requests termination, Rongfeng shall pay: Xi’an TCH’s total investment amount plus Xi’an TCH’s average annual investment return times (five years minus the years of which the system has already operated); 2) if it is more than five years into the term when Rongfeng requests the termination, Rongfeng shall pay: Xi’an TCH’s total investment amount minus total amortization cost (the amortization period is 10 years).

The first 800 million watt hours generated by the Chengli Project will be charged at RMB 0.42 ($0.068) per kilowatt hour (excluding tax); thereafter, the energy saving fee will be RMB 0.20 ($0.036) per kilowatt hour (excluding tax). The operating time shall be based upon an average 8,000 hours annually. If the operating time is less than 8,000 hours per year due to a reason attributable to Chengli, then time charged shall be 8,000 hours a year, and if it is less than 8,000 hours due to a reason attributable to Zhonghong, then it shall be charged at actual operating hours. The construction of the Chengli Project was completed in the second quarter of 2015 and the project successfully completed commissioning tests in the first quarter of 2017. The Chengli Project is now operational, but will not begin operations until the Company receives the required power generating license, which the Company anticipates receiving in the third quarter of 2017. When operations begin, Chengli shall ensure its coking production line works properly and that working hours for the CDQ system are at least 8,000 hours per year, and Zhonghong shall ensure that working hours and the CDQ WHPG system will be at least 7,200 hours per year.
