The Supplier may suspend at short notice the supply of the abovementioned types of gas (with the exception of gas for use in glass
furnaces) under special circumstances, such as when acting in concert with planned maintenance or in execution of the gas marketing contingency plan. In such event, upon the completion of maintenance or the execution of the gas marketing contingency
plan, the Supplier shall resume gas supply in a timely manner. Regarding the supply of gas for use in glass furnaces, the Supplier shall supply gas according to the average gas flow per hour calculated based on the Daily Gas Supply stipulated in
this Agreement. In the event of pipeline explosion or other emergencies that dictate suspension of gas supply, or upon receiving request for suspension due to other circumstances with reasonable notice, the Supplier shall suspend the gas supply in a
cooperative manner. Glass furnaces factories must set up the relevant security and insulation facilities and contingency mechanisms. 
 For users that use more than one type of gas, the gas price shall be billed and settled in every settlement period according to percentage of different types of gas set out in the Structure of Gas Supply
above. If the actual structure of gas usage is different, the User shall provide materials in relation to the actual structure of gas usage, which, after being verified, can be used as basis to adjust the settlement. 

In the event that the User uses up the Annual Gas Supply before the term of the Agreement expires, the Supplier may, as the case may be,
suspend the supply of gas to the User until the parties reach a gas supply Agreement for the following year. 
 (2) Verification
of Type of Gas and Structure of Gas Usage 
 Gas prices shall be calculated separately according to the Type of Gas. If such
separate calculations are not in place yet, the User shall provide the details of Type of Gas and Structure of Gas Usage, of which the User reserves the right to conduct verification whenever necessary.

 To ensure that the User stably and safely
uses gas and in order to ensure that the Supplier will receive the gas payments, this Agreement adopts the following methods of billing and settlement for the prepayment of gas supply. 

(1) Payment period for gas supply: After the Agreement is signed and goes into effect, when the User first uses the gas supply in 2011,
he should remit the initial prepayment amount to the Supplier’s account before April 1, 2011. For future payments, the User should remit the next period’s prepayment amount to the Supplier’s account before the last day of the
prior settlement period. Should the Supplier not receive the next period’s gas supply prepayment, the Supplier will stop the provision of gas once the User finishes the using the gas supply provided from previous prepayments. If both parties
have not signed a gas supply Agreement for 2012 by December 31, 2011 yet both parties still continue to supply and use gas, then both parties will temporarily carry out billing and settlement according to the provisions in the Agreement for
2011 until a supply Agreement for the next year is signed. 
 (2) Every time the User prepays one settlement period, which is 45
days’ payments of gas supply, the prepayment amount shall be RMB6.55 million. 
 (3) The Supplier will base the settlement
of gas payments on the gas intersection measurement value and starting ten days before next month and on a monthly basis, shall issue a gas invoice to the User. 
 (4) Three days before a settlement period ends the Supplier shall either via written or telephone communication notify the User to prepay the following period’s gas payment. The User should prepay
the following period’s gas payment before the end of the prior settlement period (the balances for a settlement period should be added to the remaining balances in originally prepaid payments as the payment of a whole settlement period). If at
the end of the prior settlement period the Supplier has not received the User’s prepayment for the following period, the Supplier will not notify the User and will discontinue the supply of gas once the User completely uses up its last fully
prepaid gas supply. All consequences from this will be borne solely by the User. 
 (5) Gas payment method: Before the end of
each settlement period the User should use the method of bank transfer to prepay the following period’s gas payments to the Supplier’s bank account. The User may not change the Supplier’s bank and bank account number agreed upon in
this Agreement with formal written notification from the Supplier.
