Dear Sir,

Subject: Indonesia's Lawsuit against PTTEP relating to the Montara Incident

Reference: Letter No. PTTEP 13061/00-3959/2017, dated 8 May 2017

Reference is made to PTT Exploration and Production Public Company Limited (PTTEP)'s letter no. PTTEP 13061/00-3959/2017 dated 8 May 2017 with respect to the clarification on news reporting in relation to the lawsuit pursued by Indonesian government concerning the Montara incident.

PTTEP would like to inform that we have received the Statement of Claim filed by the Ministry of Environment and Forestry of the Republic of Indonesia seeking approximately USD 2.1 billion for damages. The company will proceed to defend against this lawsuit.

The company maintains our position, based on the independent scientific research overseen by the Australian Government, that no oil from Montara reached the shores of Indonesia or Australia and that no long-term damage was done to the environment in the Timor Sea.

Sincerely yours,

Somporn Vongvuthipornchai
