(English Translation) Ref. No. SS. / 0117 / 2010 8 February 2010 Subject : Notification of additional details related to the Terms and Conditions Governing Rights and Obligations of the Warrant Issuer and the Warrant Holders of the Warrants representing Rights to Purchase Ordinary Shares of Sansiri Public Company Limited No. 1 (SIRI-W1) To : President The Stock Exchange of Thailand This is made in reference to the issuance and allocation of Warrants representing Rights to Purchase Ordinary Shares of Sansiri Public Company Limited No. 1 (SIRI-W1) (the "Warrants") as at 20 January 2010, by Sansiri Public Company Limited (the "Company"). In such regard, the Company duly distributed Terms and Conditions Governing Rights and Obligations of the Warrant Issuer and the Warrant Holders of the Warrants representing Rights to Purchase Ordinary Shares of Sansiri Public Company Limited No. 1 (SIRI-W1) (the "Terms and Conditions") to holders of the Warrants. The Company hereby informs you that as appears in the Terms and Conditions, the item no. 5 (e) (on page 18 of the Terms and Conditions) originally provides that the Company shall adjust exercise price and/or exercise ratio under the Warrants in case the Company makes dividend payment from more than 80% of net profit as appearing in the Company's consolidated financial statements after deduction of every reserved fund as required by law or by the Company for the operating result in any fiscal year during the term of Warrants; however, the definition of the variable "R" (on page 19 of the Terms and Conditions) in the relevant calculation formula deviates from the original conditions upon which the mentioned formula is based, as it is defined as "dividend per share calculated from dividend paid out of 80% of net profit after income taxes, as appearing in the Company's financial statements at the rate of as per the number of shares entitled to receive the dividend". This is merely because of a typographical error. Therefore, the Company would like to advise the holders of the Warrants to whom the Warrants were allotted, including any future transferees of the Warrants from any preceding holders of the Warrants, that the definition of the mentioned variable "R" appearing in the relevant calculation formula for adjusting exercise price and/or exercise ratio under the Warrants under the item 5 (e) (on page 19 of the Terms and Conditions) shall be modified to be in line with the original condition upon which the mentioned formula is based. The definition of the variable "R" shall be modified as follows: "R represents dividend per share calculated from dividend paid out of 80% of net profit as appearing in the Company's consolidated financial statements after deduction of every reserved fund as required by law or by the Company at the rate of as per the number of shares entitled to receive the dividend." In this regard, holders of the Warrants may request a hard copy of the mentioned modified Terms and Conditions by disclosing such intention toward the Company to the following address: Legal Office Sansiri Public Company Limited 475, 16th floor Siripinyo Building, Sri Ayudhaya Road, Kwaeng Phayathai ,Khet Rajthevi, Bangkok 10400 Tel : 0 2201 3816 Fax : 0 2201 3477 Upon receipt of such request, the Company would deliver the modified Terms and Conditions to the requesting holder of the Warrants within 15 days.
