Description of long-term contract for purchase of electric power             The construction period of the Project is expected to be 18 months from the date when conditions are ready for construction to begin. Zhongtai will start to pay an energy saving fee from the date when the WHPG station passes the required 72-hour test run. The term of payment is 20 years. For the first 10 years of the term, Zhongtai shall pay an energy saving fee at RMB 0.534 ($0.089) per KWH (including value added tax) for the power generated from the system. For the second 10 years of the term, Zhongtai shall pay an energy saving fee at RMB 0.402 ($0.067) per KWH (including value added 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. Zhongtai shall also pay an energy saving service fee for the steam supplied by Xi'an TCH at RMB 100 ($16.67) per ton (including value added tax). Zhongtai and its parent company will provide guarantees to ensure Zhongtai will fulfill its obligations under the Agreement. Upon the completion of the term, Xi'an TCH will transfer the systems to Zhongtai at RMB 1 ($0.16). Zhongtai shall provide waste heat to the systems for no less than 8,000 hours per year and waste gas volume no less than 150,000 Nm3 per hour with a temperature no less than 950°C. If these requirements are not met, the term of the Zhongtai Agreement will be extended accordingly. If Zhongtai wants to terminate the Zhongtai 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: (i) if it is less than five years into the term when Zhongtai requests termination, Zhongtai shall pay: Xi'an TCH's total investment amount plus Xi'an TCH's annual investment return times five years minus the years in which the system has already operated; or (ii) if it is more than five years into the term when Zhongtai requests the termination, Zhongtai shall pay Xi'an TCH's total investment amount minus total amortization cost (the amortization period is 10 years).
