With reference to the case which CAT Telecom Public Company Limited ("CAT") has submitted a dispute to the Arbitration Institute, ref. no. Black 3/2551, demanding Digital Phone Co., Ltd., ("DPC"), a subsidiary of Advanced Info Service Public Company Limited (the "Company") which 98.55% of its shares are held by the Company, to pay additional revenue sharing for the total amount of Baht 3,410 million due to the deduction by DPC of the excise tax from the revenue sharing delivered during 28 January 2003 to 26 February 2007. The Company would like to inform of the Arbitral Tribunal's Award of the above-mentioned case that on 1 March 2011 the Arbitral Tribunal has dismissed the case by giving the reason which can be summarized that DPC was not in breach of the Agreement since DPC has completely made the payment of the revenue sharing and all debt was therefore paid in full. Therefore, CAT has no right to re-claim for the alleged deficit amount, including the penalty and the value added tax. ______________________________________________________________________
