Instructions for Filling Out the Proxy Form:

1. Shareholders who attend the meeting in person may not authorize another person for part of their shareholding. If both the attendance card and proxy form are signed or stamped, the Company will deem this as an in-person attendance, unless the proxy form is submitted by the shareholder to a solicitor or proxy agent, in which case it will be treated as a proxy attendance.

2. The appointing shareholder and the proxy shall comply with the “Regulations Governing the Use of Proxies for Attendance at Shareholder Meetings of Public Companies” and Article 177 of the Company Act.

3. Only the Company-issued proxy form may be used. Each shareholder may issue one proxy form and authorize one person only.

4. Prior to accepting a solicitation for proxy, the shareholder should carefully review the background of the solicitor and the candidate they support, and understand their stance on meeting proposals, either through materials provided by the solicitor or the Company’s consolidated disclosures.

5. If the proxy is not a shareholder, please provide their National ID No. or Business Registration No. in the shareholder account number field.

6. If the solicitor is a trust enterprise or stock affairs agency, please provide the Business Registration No. in the shareholder account number field.

7. If a proxy form has been submitted, but the shareholder later wishes to attend the meeting in person or vote in writing or electronically, a written revocation must be sent to the Company at least two days prior to the meeting. If not revoked in time, the proxy vote shall prevail.

Sincerely,

The Board of Directors
