The press release announcing this material change was issued on August 13, 2018 in Canada and the United States.

4. SUMMARY OF MATERIAL CHANGE

Methanex Corporation announced on August 13, 2018 that it has signed agreements with Pan American Sur SA, Compañia General de Combustibles SA, Total Austral SA and Wintershall Energia SA for additional gas supply through to June 1, 2020.


5.	FULL DESCRIPTION OF MATERIAL CHANGE


5.1	FULL DESCRIPTION OF MATERIAL CHANGE

The signed agreements with Pan American Sur SA, Compañia General de Combustibles SA, Total Austral SA and Wintershall Energia SA are for additional gas supply on an interruptible basis and subject to gas availability in Argentina for its Chile operations through to June 1, 2020.

These agreements are subject to the gas suppliers obtaining export permits from the Argentine Government and, based on the policy direction signaled by the Argentine Government, we are optimistic that the export permits will be granted. It is expected that these new agreements, combined with existing contracts from other gas producers, will allow for a two-plant operation in Chile during the southern hemisphere summer months and up to a maximum of 75% of a two-plant operation annually.
