(Translation) No. CK-07-0000-PO-L-0019 January 22, 2007 Re: Exercise of Right to Subscribe for Capital Increase Shares in Pathum Thani Water Co., Ltd. Attn.: President of the Stock Exchange of Thailand Reference is made to the fact that CH. Karnchang Public Company Limited informed the Stock Exchange of Thailand that Pathum Thani Water Co., Ltd. ("PTW") had restructured itself by increasing its registered capital from Baht 1,102,000,000 (11,020,000 shares) to Baht 2,752,000,000 (27,520,000 shares), by issuing new 16,500,000 ordinary shares at the par value of Baht 100 per share and allocating 16,500,000 shares for capital increase to the existing shareholders according to their shareholding ratio. The Company hereby informs that the Company has exercised its right to subscribe for 7,025,700 capital increase shares in PTW according to its shareholding ratio at the par value of Baht 100 per share, in the amount of Baht 702,570,000, in order to maintain its shareholding ratio of 42.58 percent of the registered capital in PTW. Moreover, since there were certain existing shareholders not exercising their rights to subscribe for capital increase shares, the Company therefore has also exercised its right to subscribe for another 1,049,818 capital increase shares, according to its ratio, from the existing shareholders who did not exercise their rights, at the par value of Baht 100 per share, in the amount of Baht 104,981,800. The total number of subscribed shares was 8,075,518 shares, in the total amount of Baht 807,551,800 (the subscription for capital increase shares from the existing shareholders who did not exercise their rights was the exercise of right according to the shareholding ratio of each shareholder, whereby no shareholder exercised the right exceeding its ratio or waived the right to subscribe for shares from the shareholders who did not exercise their rights). Such exercise of the right to subscribe for shares then rendered the Company holding 12,767,838 shares in PTW, representing 46.39 percent of the total shares of 27,520,000 shares. In this regard, the shareholders of PTW who have subscribed for capital increase shares shall pay for such shares by January 25, 2007. PTW will receive payment from such capital increase in the total amount of Baht 1,650,000,000. PTW will use the money received from the capital increase in the amount of Baht 300,000,000 to purchase shares in BJT Water Co., Ltd., and the remaining amount will be used for repayment of the loan under the Sponsors Support Agreement. Please be informed accordingly. Very truly yours, - Signature - (Mr. Anukool Tuntimas) Executive Vice President Human Resource and General Administration
