(1) Shareholders who attend the virtual meeting may cast their votes on various proposals and elections via the virtual meeting platform after the chairman declares the meeting has convened and shall complete the casting prior to the moment when the chairman declares the closing of the voting session or otherwise shall be deemed to abstain from voting. Shareholders may also raise their questions in text form on the virtual meeting platform. No more than two questions for the same proposal may be raised and each question shall contain no more than 200 words. Please check the TDCC website.

4. (2) Shareholders who plan to attend the meeting virtually must sign up for it and register such attendance on the TDCC e-Meeting Platform between 2024/5/11 and 2024/6/9. The said process can be completed by scanning the QR Code above with mobile devices. Online participants can start checking in 30 minutes prior to the shareholder meeting. Once

shareholders complete the check-in process, they are deemed as having attended in person. If the appointed proxy wishes to attend the meeting virtually, the appointed proxy should fill out the "Willingness Letter for the Appointed Proxy to Participate in the Shareholders' Meeting via Video Conferencing Registration" and submit it to the shareholder services department of the shareholder services agency, Oriental Securities Corp.(OSC), before 4 pm on 2024/6/7, for registration and record.

• (3) Please contact the shareholder services agency, Oriental Securities Corp.(OSC) (02-77531699) or the TDCC (02-2514-1288) if you have any questions about online participation, such as registration, check-ins, connection methods, and platform operating matters. The Company will not be liable for any poor communications, broadcast lags, or any difficulties concerning watching a live stream, texting questions, and exercising voting rights if it is shareholders’ internet connection or equipment that causes the problems. Shareholders who have concerns about such issues are encouraged to use e-voting prior to the meeting or attend the meeting in person.

• (4) Countermeasures for postponing or reconvening the meeting:

• i. Shareholders who have not registered their online attendance at the affected meeting will not be allowed to attend the postponed or reconvened meeting.

• ii. In the event that the e-Meeting Platform fails or shareholders have difficulty attending virtually for over 30 minutes due to natural disasters, incidents, or other force majeure events, the Company should check the total shares of shareholders that have attended. If the total number of shares represented at the shareholder meeting after deduction of the number of shares represented by shareholders attending virtually still reaches the legal quorum for convening of the shareholders' meeting, the affected meeting will continue in session. The shares of shareholders, solicitors, or proxy agents who attend virtually will be counted towards the total number of shares represented by the shareholders attending the meeting. In addition, shareholders, solicitors, or proxy agents who attend virtually will be deemed to abstain from voting on all proposals on meeting agenda of that shareholder meeting. Please contact the shareholder services agency, Oriental Securities Corp.(OSC) (02-7753-1699) if you encounter the said situation.

• iii. If encountering the said problems, the chairperson may adjourn the meeting when outcomes of all proposals have been announced and an extraordinary motion is not put forward.
