Article 1 Except as otherwise provided by law and regulation or by the Company's Articles of Incorporation, elections of directors shall be conducted in accordance with these Procedures.

Article 2 The Company shall employ the registered cumulative voting method for the election of its directors. Each share shall be entitled to a number of voting rights equal to the number of directors to be elected and may be cast for a single candidate or distributed among multiple candidates. The election of directors shall be calculated separately based on the election of independent directors and non-independent directors. The Company has implemented a candidate nomination system for the election of directors. All matters related to the acceptance and announcement of candidates will be handled in compliance with the relevant laws and regulations outlined in the Company Act and the Securities and Exchange Act.

Article 3 The number of directors of the Company shall be determined in accordance with the provisions of the Company's Articles of Incorporation, and those receiving ballots representing the highest numbers of voting rights will be elected sequentially according to their respective numbers of votes. When two or more persons receive the same number of votes, thus exceeding the specified number of positions, they shall draw lots to determine the winner, with the chair drawing lots on behalf of any person not in attendance.

Article 4 The Board of Directors will prepare separate ballots for the directors to be elected, with the number of ballots corresponding to the number of positions available. The number of voting rights associated with each ballot will be specified and the ballots will be distributed to attending shareholders at the shareholders' meeting. Instead of recording the names of voting shareholders, attendance card numbers printed on the ballots may be used. Prior to the election, the chair will appoint individuals with shareholder status to serve as vote monitoring and counting personnel. The Board of Directors will prepare the ballot boxes, which will be publicly checked by the vote monitoring personnel before voting begins.

Article 5 A ballot is invalid under any of the following circumstances:

1. The ballot was not prepared by a person with the right to convene.
2. A blank ballot is placed in the ballot box.
3. The writing is unclear and indecipherable or has been altered.
4. The candidate whose name is entered in the ballot does not conform to the director candidate list.
5. Other words or marks are entered in addition to the number of voting rights allotted.

Article 6 The eligibility of independent directors shall be aligned with provisions of Regulations Governing Appointment of Independent Directors and Compliance Matters for Public Companies and Corporate Governance Best Practice Principles for TWSE/TPEx Listed Companies.

Article 7 The overall composition of the Board of Directors shall be taken into consideration in the selection of the Company's directors. Each board member shall have the necessary knowledge, skills, and experience to perform their duties, and their overall competencies should be selected with reference to the Corporate Governance Best Practice Principles for TWSE/TPEx Listed Companies.

Article 8 The voting rights shall be calculated on site immediately after the end of the poll, and the results of the calculation shall be announced by the chair or specific personnel on the site.

Article 9 The Board of Directors of the Company shall issue notifications to the persons elected as directors.
