Some securities to be traded on a call market basis

Some securities to be traded on a call market basis Securities of firms not meeting regulations of The Stock Exchange of Thailand (SET) on minority shareholding will be traded on a call market basis. According to SET regulations, "Maintaining the Status of Listed Companies on the Exchange", all such firms must have at least 150 minority shareholders of common stock,holding at least 15% of paid-up capital in total, as shown by the shareholder list used for the firms annual general meeting. Any company not meeting this requirement has one year to rectify the situation. Should a company not meet these conditions within a year, SET will consign its securities to be traded on a call market basis. There are 5 companies who, for two consecutive years, have not satisfied the "minority shareholder" requirement. Consequently, SET will consign their securities to be traded on a call market basis,from July 12, 2006, until the situation is rectified. 1. From July 12, 2006, common shares of these companies will be traded on a call market basis : 1.1. Samitivej PCL (SVH) 1.2. City Sports and Recreation PCL (CSR) 1.3. PAE (Thailand) PCL (PAE). As this company is now in rehabilitation, its securities are under suspension (SP),and not being traded. 2. Trading on a call market basis is deferred for two companies: 2.1. Dusit Thani PCL (DTC) securities will be traded on a call market basis, effective November 15, 2006, should company not meet the "minority shareholder" requirement by October 31, 2006. 2.2.

(SAWANG) 369 350 9.59 9.57 The "call market" The "call market" is a trading method that automatically matches buy and sell orders at a specific time and price ("Single Price Auction"). Buy or sell offers are made just as they are in regular trading. However, the trading system randomly matches buy and sell orders at only three specific times: 1. pre-opening of the morning session (09:55 - 10:00 hours) 2. pre-opening of the afternoon session (14:25 - 14:30 hours) 3. close of the trading day (16:35 - 16:40 hours) Call market sequencing of buy or sell orders operates in the same way as the continuous-order matching method, using the best bid or offering price and timing order ("Price and Time Priority"). The securities remain in their original sectors, but a "CM" sign is posted indicating that they are being traded on a call market basis. Listing and Disclosure Department
