Subject: Clarification of news of litigation by the Ombudsman in relation to PTT Public Company Limited's conduct in accordance with a judgment of the Supreme Administrative Court

To: President,

The Stock Exchange of Thailand

Reference: Letter from PTT Public Company Limited to the President of the Stock Exchange of Thailand No. 80000001/329 dated 11 April 2016 re: Supreme Administrative Court reaffirmed that PTT has transferred all assets to the state completely in accordance with the judgment.

On 4 April 2016, the Ombudsman filed a lawsuit against the Ministry of Finance and 11 others, including PTT Public Company Limited ("PTT"), at the Central Administrative Court claiming that PTT failed to return a natural gas pipeline in accordance with a judgment of the Supreme Administrative Court.

PTT would like to inform you that today (27 May 2016), PTT has formally received a Court order dated 26 May 2016 from the Central Administrative Court requesting PTT to submit the statement of defence for the Black Case No. 510/2559 within 30 days from the receipt date. The court order is requested PTT to clarify only one issue that whether or not PTT have completely complied with the Cabinet Resolution on 18 December 2007 in relation to the separation of the assets of Petroleum Authority of Thailand on parts which are considered as the State property that are required to transfer to Ministry of Finance (the 1stRespondent). In addition, the court order also stated that the court dismissed the claim brought against the 2nd, 3rd, 4th, 6th. 7th, 8th, 9thand 11thRespondents which all are individuals.

From consideration of the content of the aforementioned complaint, PTT is of the view that the issue in the allegations made by the Ombudsman in the lawsuit against PTT is the same as an issue which appears in a case on which the Supreme Administrative Court has already rendered a final and binding judgment. In Supreme Administrative Court Red Case No. For. 35/2550, including other various petitions and orders, the Court has always held that PTT and the related agencies had completed the transfer of assets in accordance with the judgment. In the most recent case, the Supreme Administrative Court, by the General Assembly of the Supreme Administrative Court, rendered a final judgment on this matter stating that the petition

by the Foundation for Consumers et al (the claimants in that case), along with a document stating the opinion of the Ombudsman, constituted a prohibited petition as the Supreme Administrative Court had already rendered a judgment on that matter. The Court therefore issued an order not to accept the aforementioned petition for consideration with details as stated in the Reference Letter

With regard to the above, PTT shall submit the statement of defence to the court and proceed to defend the case pursuant to a proper legal proceedings. If there is any further development, PTT shall inform you of the results accordingly.

PTT would like to inform you that PTT respects differing opinions on the issue of the return of assets to the Ministry of Finance in accordance with the Court's judgment. In any case, PTT is of the view that the Court is the highest resort with the authority to adjudicate on the return of assets to the Ministry of Finance in accordance with the Court's judgment, and as the Court has rendered a judgment which is final and binding, PTT cannot act in a manner which contravenes the judgment and decision of the Court.

Please be informed accordingly.

Yours Sincerely,
