I. Quality Requirements and Conditions for Assuming Responsibility for Quality

　　A penalty‑based pricing system is implemented for product quality: if the quality of the goods supplied exceeds the specified standards, settlement will be based on a reduction in the unit price. The specific procedures are as follows:

1. Puyang Coal

　　(1) When the applicable lower heating value is ≥ 4,000 kcal and < 4,200 kcal, a discounted purchase shall apply; the settlement price for this batch shall be: Contract unit price + 4,200 × Measured calorific value × 0.97. When the applicable lower heating value is ≥ 3,800 kcal and < 4,000 kcal, the buyer has the right to refuse acceptance and warehousing, and shall arrange for return or exchange; the seller shall bear all costs associated with such return or exchange. If the buyer agrees to accept, the settlement unit price shall be: Contract unit price + 4,200 × Measured calorific value × 0.87.

　　(2) When the received‑basis total moisture is greater than 22% but not more than 24%, a price reduction shall be applied. The price reduction shall be calculated as follows: if the received‑basis total moisture exceeds the quality standard, the reduction amount equals the contract unit price multiplied by the difference between the measured total moisture and the standard total moisture. If the total moisture of coal delivered to the plant exceeds 2%, the buyer has the right to refuse acceptance and arrange for return or exchange; if the coal has already been accepted into storage, a price reduction shall be applied, with the reduction amount equal to the contract price multiplied by the difference between the measured total moisture and the standard total moisture, then multiplied by 2.

　　(3) Upon receipt, if the total sulfur content exceeds 0.9%, returns or exchanges shall, in principle, be processed; if unloading has already taken place, a price reduction shall be applied, calculated as follows: for every 0.1% by dry basis that the total sulfur content exceeds the standard (with any fraction of 0.1% or less treated as 0.1%), a deduction of RMB 3 per ton shall be made. If the total sulfur content by dry basis exceeds 1.1%, the buyer shall have the right to refuse acceptance into storage and to return the goods; if the goods have already been stored, a price reduction shall be applied, with the excess portion above 1.1% subject to a deduction of RMB 6 per ton, calculated in the same manner as above.

　　(4) When the volatile matter content is ≥28% and <30%, the batch shall be subject to a deduction of RMB 5 per ton.

　　(5) When the fixed carbon content is ≥28% and <30%, the batch shall be subject to a deduction of RMB 5 per ton.

　　(6) When the ash content exceeds 10%, the batch shall be subject to a deduction of RMB 5 per ton.

2. Luliang Coal

　　(1) When the lower heating value on an as‑received basis is ≥ 3,600 kcal and < 3,800 kcal, a discounted purchase shall apply, with the settlement price for that batch calculated as: Contract unit price + 3,800 × measured calorific value × 0.97. If the lower heating value on an as‑received basis is < 3,600 kcal, the buyer shall refuse to accept the goods into storage; however, if the buyer agrees to accept them, the settlement price shall be calculated as: Contract unit price + 3,800 × measured calorific value × 0.87.

　　(2) When the total moisture content is greater than 28% but not more than 30%, a price reduction shall be applied. The price reduction shall be calculated as follows: for each percentage point by which the measured total moisture exceeds the standard, the reduction amount equals the contract unit price multiplied by the difference between the measured total moisture and the standard value. If the total moisture of coal delivered to the plant exceeds 30%, the buyer has the right to refuse acceptance and arrange for return or exchange; if the coal has already been accepted, a price reduction shall be applied, with the reduction amount equal to the contract unit price multiplied by twice the difference between the measured total moisture and the standard value.

　　(3) Upon receipt, if the total sulfur content exceeds 0.5%, return or exchange shall, in principle, be effected; if unloading has already taken place, a price reduction shall be applied, calculated as follows: for every 0.1% by dry basis that the total sulfur content exceeds the standard (with any fraction less than 0.1% rounded up to 0.1%), a deduction of RMB 3 per tonne shall be made. If the total sulfur content by dry basis exceeds 0.7%, the buyer shall have the right to refuse acceptance into storage and to return the goods; if the goods have already been stored, a price reduction shall be applied, with the excess portion above 0.7% subject to a deduction of RMB 6 per tonne, calculated in the same manner as above.

　　(4) When the volatile matter content is ≥28% and <30%, the batch of products shall be subject to a deduction of RMB 5 per ton.

　　(5) When fixed carbon is ≥28% and <30%, the batch shall be subject to a deduction of RMB 5 per ton.

　　(6) When the ash content exceeds 12%, the batch shall be subject to a deduction of RMB 5 per ton.
