Karnchang Public Company Limited, held on December 21, 2004, resolved to grant approval for the Company to sell and/or waive its option to purchase capital increase shares, and/or transfer the option to purchase ordinary shares in SouthEast Asia Energy Limited, which might occur in the future, to other persons and/or legal entities to join the investment at the rate of 65-75 percent of the company's registered capital, so that the Company would hold shares only 25-35 percent of the registered capital. In addition, on October 20, 2005, the Company informed the Stock Exchange of Thailand that the Company sold 1,250,000 ordinary shares in SouthEast Asia Energy Limited to Bangkok Expressway Public Company Limited. At present, the Company hereby informs you that the Company has already sold 10,000,000 ordinary shares in SouthEast Asia Energy Limited to Ratchaburi Electricity Generating Holding Public Company Limited. Such 10,000,000 shares were divided into 2,500,000 shares which have been fully paid-up, at the price based on the par value of Baht 10 per share, amounting to Baht 25,000,000, while the other 7,500,000 shares, merely 25 percent of which have already been called and paid-up, were therefore sold by the Company at the price of Baht 2.50 per share, amounting to Baht 18,750,000, thereby totaling Baht 43,750,000. Furthermore, the Company has purchased 400,000 ordinary shares in SouthEast Asia Energy Limited from Shlapak Development Company (an existing shareholder without any connection with the Company) and 400,000 ordinary shares from P.T. Construction & Irrigation Company Limited (an existing shareholder without any connection with the Company), at the price of Baht 2.50 per share, thereby totaling Baht 2,000,000. As a result, the Company currently holds 21,799,995 shares representing 54.50 percent of the registered capital in SouthEast Asia Energy Limited (formerly the Company held 30,999,995 shares representing 77.50 percent of the registered capital in SouthEast Asia Energy Limited).
