Dear Sir,

Subject: Signing of Gas Sales Agreement for Bongkot South Field

Reference is made to the Bongkot Project, operated by PTT Exploration and Production Public Company Limited (PTTEP) with the participation interest of 44.4445%, and other joint venture partners; Total E&P Thailand and BG Asia Pacific PTE Ltd, holding participation interests of 33.3333%, and 22.2222%, respectively. PTTEP and the joint venture partners have previously agreed on pursuing the development of the Bongkot South Field, which is in the southern area of Bongkot Concession Area.

PTTEP wishes to announce that the Company and the joint venture partners (the sellers) have officially signed the Gas Sales Agreement (GSA) for the Bongkot South Field with PTT Public Company Limited or PTT (the buyer). Under the GSA, the Daily Contractual Quantity (DCQ) for natural gas is 320 million cubic feet per day (MMSCF/D). The planned production start-up period will be within the middle of 2012 to the middle of 2013.

Bongkot, which has been on production since 1993, is the biggest gas field in the Gulf of Thailand. The DCQ for natural gas for the existing Bongkot Project is 550 MMSCF/D. The signing of the GSA for the Bongkot South Field will raise the DCQ of the Bongkot Project to 870 MMSCF/D and represents another PTTEP major achievement to expand its production base, in order to reduce petroleum import and secure long-term gas supply of the nation.

Dear Sir,

Subject: Participation in Petroleum Concession Block G4/48

Reference is made to the 19th Petroleum Concession Bidding Round of the Department of Mineral Fuels. PTT Exploration and Production Public Company Limited or PTTEP would like to announce that PTTEP (Thailand) Limited, a subsidiary of PTTEP, has been granted approval to participate in the Petroleum Concession Block G4/48.

An official signing ceremony between the Ministry of Energy and PTTEP (Thailand) Limited together with the consortiums takes place on July 24, 2009. Concession Block G4/48, covering an area of approximately 504 square kilometers, is adjacent to Unocal 3 Project in the Gulf of Thailand. Chevron Pattani Limited (the operator) holds 71.25% interest, Mitsui Oil Exploration Company Limited (Moeco) and PTTEP (Thailand) Limited hold 23.75% and 5% interests respectively.

Regarded as a marginal field, the most appropriate development operation for Petroleum Concession Block G4/48 is to use the existing facilities in Unocal 3 Project. This plan will make the Block G4/48 commercially feasible and also raise the economics of both projects.

Dear Sir,

Subject: Withdrawal of participation in Indonesia Merangin 1 project and Bangladesh 17 and 18 project

PTT Exploration and Production Public Company Limited (PTTEP) wishes to announce that PTTEP has reviewed the company’s exploration project portfolio in accordance with the company’s strategy under the current economic environment. After careful analysis based upon technical result and the return on investment, the company decides to withdraw its participation in two petroleum exploration projects with the following details:

1. Indonesia Merangin 1 project.

PTTEP Merangin Company Limited (a subsidiary of PTTEP), participation interest in the block is 40%. Exploration wells that have been drilled in the area have resulted in non-commercial discovery. The completion of withdrawal process is subject to official approval from Indonesian government authorities.

Currently, PTTEP has two other exploration projects in Indonesia, which are Bengara-1 and Semai II.

2. Bangladesh 17 and 18 project.

PTTEP Bangladesh Limited holds a 30% participation interest in this project. With low potential for commercial discovery, the company wishes to withdraw from this block.

However, PTTEP continues to look for investment opportunity in projects that fit company long-term strategies, where the People’s Republic of Bangladesh is still considered as one of the focus countries.
