(-Translation-) Ref. BTS 2118 /2010 May 7, 2010 Subject: Sector and Industry Group Reclassification To: President The Stock Exchange of Thailand BTS Group Holdings Public Company Limited (formerly known as Tanayong Public Company Limited) (the "Company") has operated in the real estate development business and has been listed on the Stock Exchange of Thailand in Property Development Sector under Property & Construction Group. However, recently the shareholders of the Company resolved to approve the Company to purchase ordinary shares of Bangkok Mass Transit System Public Company Limited ("BTSC") in the amount equivalent to 94.60% of the total issued shares of BTSC from the shareholders of BTSC (the "BTSC Share Acquisition") as per the details informed earlier. BTSC is a company operating in the public transportation business. The Company would like to inform that the Company has completed the BTSC Share Acquisition on May 4, 2010. After the BTSC Share Acquisition, the Company has not yet had a plan to change the business of the Company or BTSC. The Company will continue operating in its real estate development business and BTSC will continue operating in its public transportation business. However, the revenue from the skytrain fares generated by BTSC will be the core revenue of the Company's group in the future where the revenue from the real estate development projects will be in the lesser proportion. Accordingly, for the clear understanding and perception of the investors toward the change in the assets and core revenue of the Company, the Company would like to request the Stock Exchange of Thailand to consider changing the Company's trading sector and industry to Transportation & Logistics Sector under Services Group to correspond with the change in the assets and core revenue of the Company. Please be informed and proceeded accordingly. Yours sincerely, BTS Group Holdings Public Company Limited - Mr. Sutham Siritipsakorn / Mr. Rangsin Kritalug- Directors
