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
