As a result, the total legal reserve of the Company shall give an amount of 23,821,500 baht or equivalent to 8.66 percent of the registered capital. Voting: The resolution of this agenda shall be passed by a simple majority of the shareholders present at the Meeting and entitled to vote (excluding the abstention). Agenda 5 To consider and approve the dividend payment for the year 2020 Facts and rationale: The Public Company Limited Act B.E. 2535 (1992) and the Articles of Association of the Company provide that no dividend shall be paid otherwise than out of profits, and in the case where the Company still sustains an accumulated loss, no dividend shall be paid. In addition, the Company also has the policy to pay dividend at the rate of not less than 40 percent of the net profit after deduction of the legal reserve. Opinion of the Board of Directors: The Company had the net profit of 50,356,953 baht for the year 2020 (Separate Financial Statements), and also had the unappropriated retained earnings. The Board of Directors considered the Public Company Limited Act, the Company’s Articles of Association, operating results, financial position, and interests of the shareholders. Nevertheless, the Board of Directors may sometimes consider not to follow the dividend policy depending on the operating results, investment plans, liquidity, necessity, and other appropriate circumstances in the future, as it shall deem appropriate. As a result, the Board of Directors deemed it appropriate to propose the shareholders’ meeting to approve the dividend payment for the year 2020 to the shareholders amounted to 35,200,010 baht, or equivalent to 69.90 percent of the net profit (Separate Financial Statements). The dividend shall be paid in cash to the shareholders of the Company, totaling 440,000,125 ordinary shares, at the rate of 0.08 baht per share. The allocation of net profit and dividend payment are in line with the Company’s policy. Moreover, the natural person shareholders are entitled to a tax credit equal to the dividend multiplied by 20/80 according to the Revenue Code, Section 47 Bis. The dividend amounted to 35,200,010 baht was distributed from the profit, which was subject to corporate income tax of 20 percent.

Voting: The resolution of this agenda shall be passed by a simple majority vote of the shareholders present at the meeting and entitled to vote (excluding the abstention).
