Agenda 4 To consider and approve the retaining of the net profit for legal reserve and the dividend payment for the 2016 operating performance Background and Rationale Allocation of the net profit for legal reserve According to the Section 116 of the Public Limited Companies Act, B.E. 2535 and Article 41 of the Company’s Articles of Association, the Company is required to set aside to a statutory reserve at least 5 percent of its net profit after deducting accumulated loss brought forward (if any) until the reserve reaches 10 percent of the registered capital. Dividend Payment The Company’s dividend allocation policy is approximately 40% of the net profit after deduction of taxation and legal reserve of the financial statements. However, the dividend payment can be changed and subject to the Company’s investment plan, necessity, other future appropriate reasons and under conditions to contribute high benefit for the shareholders such as loan repayment, investment fund for business expansion or on occasion of market environment change that may affect the Company’s cash flow in the future under the Board of Directors’ authority to consider and review the dividend policy. However, the Board of Directors’ resolution to allocate the dividend payment must be subsequently proposed to the Shareholders’ Meeting for approval except for the interim dividend payment that the Board of Directors has the authority to approve prior to informing to the subsequent Shareholders’ Meeting for acknowledgement.

Details of proposed dividend payment for the 2016 operating performance were as follows:

2016 (Proposed) 2015 4102 Net profit of the Company 357.93 Million Baht 399.13 Million Baht 255.67 Million Baht Net profit of the Company & its subsidiaries attributable to equity holders of the 290.76 Million Baht 305.96 Million Baht 214.92 Million Baht Company Legal reserve 16.10 Million Baht 15.40 Million Baht 2.87 Million Baht Net profit after legal reserve 374.03 Million Baht 383.73 Million Baht 252.80 Million Baht Form of dividend payment Stock and cash dividend Stock and cash dividend Stock and cash dividend No. of shares obtaining right for dividend 5,135,985,760 shares 4,563,502,886 shares 3,322,150,424 shares - 4 -

2016 (Proposed) 2015 4102 Dividend payment Cash dividend 20.54 MB Cash dividend 45.64 MB Cash dividend 11.54 MB (Baht 0.0040000/share) (Baht 0.010000/share) (Baht 0.003472/share) Stock dividend Stock dividend 71.30 MB Stock dividend 91.71 MB (Baht 0.015625/share) 103.82 MB (Baht 0.0178571/share) (Baht 0.031250/share) Dividend payout ratio comparing to net 30.01% 30.48% 45.63% profit after legal reserve

The proposed dividend payment for the 2016 operating performance representing 30.01% of the 2016 net profit after legal reserve was lower than the dividend policy of the Company which was at the rate of 40%. That because TRC group would like to reserve funds in 2017 to support the business expansion and the operation of large projects. (At the end of 2016, TRC group's backlog was Baht 3,680 million) The Board’s Opinion The Board approved to propose the meeting of shareholders to consider and approve the retaining of the net profit for legal reserve and the dividend payment for the operation year 2016 as follows: - Legal reserve of Baht 16,102,769 or 4.50% of the 2016 net profit resulting the legal reserve as at the end of 2016 equalled to Baht 72,637,344 or 10% of the registered capital - Dividend payment not exceeding Baht 112,257,974.29 or at the rate of Baht 0.0218571 per share as per following details: 1) Stock dividend will be issued not exceeding 733,712,250 ordinary shares with a par value of Baht 0.125 per share to the shareholders at the ratio of 7 existing shares per 1 new share or equivalent to the dividend at the rate of Baht 0.0178571 per share. If there is a fraction of share remaining, due to insufficient number of shares to be converted into shares, a cash dividend at Baht 0.0178571 per share will be paid instead. 2) Cash dividend at the rate of Baht 0.0040000 per share or not exceeding Baht 20,543,943.04. Anyway, the right for dividend payment is still uncertain since the dividend payment has to be approved by the 2017 AGM. The dates relevant to the dividend payment: - The date to determine the names of shareholders who have right to receive the dividend: 9 May 2017 - The date for gathering the names of shareholders under the Section 225 of the Securities and Exchange Act B.E.2535 (as amended) by closing the share register book: 11 May 2017 - The date for dividend payment: 26 May 2017
