-Translation- AIS-CP 023/2010 March 9, 2010 Subject: Clarification the Company's operations do not have an impact from the news. To: The President The Stock Exchange of Thailand As everyone is currently aware, the judgment of the Supreme Court, Criminal Division for Persons Holding Political Positions, rendered on February 26, 2010, concerns Advanced Info Service Public Company Limited ("AIS") in some aspects. Later on, there was a comment from an academic on the judgment [of the Supreme Court, Criminal Division for Persons Holding Political Positions] through the press that, with reference to the judgment, there were damages sustained by the government agencies arising out of amendments to the mobile phone concession agreement. He believes that the government agencies will initiate a civil case claiming a large amount of damages in this regard, and that AIS or its affiliated companies may opt to pay installments of such damages if their managements view that the business is still viable; or opt to let the company go bankrupt. Despite AIS viewing such opinion as a personal comment from a person with a non-legal background, such opinion may cause investors' understanding to greatly deviate from actuality and cause investors to lose confidence in AIS resulting in damages to AIS's image. AIS would like to explain that the judgment does not contain any ruling or analysis on the result, the validity or invalidity of the relevant law, cabinet resolution or the actions previously taken in accordance with amendments to the concession agreement concerning AIS. The consequence of the judgment is limited to the holding that some property of the person holding political position was improperly acquired by an abuse of power while being in a political position. No notice of any further conclusion has been given to AIS. Should any legal proceeding be initiated by related parties, such proceeding shall be in accordance with the law and justice. AIS will then have an opportunity to provide the facts to prove its innocence and good faith. AIS believes that the outcome of this controversy will be fair to TOT Public Company Limited, AIS and other relevant telecommunication business operators. Please be informed accordingly. Yours sincerely, -Signed- Mr. Wichian Mektrakarn Chief Executive Director Advanced Info Service Plc.
