Discussions

Motion 1

Proposal by the board of directors

Summary: The proposal for the capital increase of the Company via the private placement of ordinary shares; please discuss.

Description:

1. In response to the capital required for future development, investments or the enrichment in working capital, the Company plans to request the shareholders' meeting to authorize the board of directors to authorize the board of directors at an appropriate time in accordance with the provisions of Article 43-6 of the Securities and Exchange Act. It is expected that the number of private placement shares will no more than 20,000,000 ordinary shares. Choose one or use a combination of private placement to issue common shares, or private placement to handle domestic convertible corporate bonds.

2. According to Article 43-6 of the Securities and Exchange Act and the "Directions for Public Companies Conducting Private Placements of Securities," the descriptions are as follows:

(I) The basis and reasonableness of the private placement pricing

1. The price per share of private placement ordinary shares shall be no less than 80% of the reference price. The reference price shall be the higher of the following two calculations:

(1) The simple average closing price of the ordinary shares for either one, three or five business day(s) before the price determination date, after adjustment for any distribution of stock dividends, cash dividends or capital reduction.

(2) The simple average closing price of the ordinary shares for the 30 business days before the price determination date, after adjustment for any distribution of stock dividends, cash dividends or capital reduction.

1. Private convertible corporate bonds:

(1) Denomination: NT$100,000 or its multiples.

(2) Issuance period: not more than seven years from the issuance date.

(3) Coupon interest rate: authorize the board of directors to make decisions based on market conditions.

---

(4) The issue price of private placement convertible corporate bonds may not be below 80% of the theoretical price. The theoretical price will be determined with the valuation model selected that covers and takes into consideration at the same time various rights included in the issuance criteria. The conversion price was determined by calculating the simple arithmetic average of the closing price of the ordinary shares for one, three or five business days prior to the pricedetermination date, less the ex-rights and dividends of stock dividends, and adding back the anti-ex-rights of the capital reduction, or the simple arithmetic average of the closing price of the ordinary shares for 30 business days prior to the price determination date, less the ex-rights and dividends of stock dividends, and adding back the anti-ex-rights of the capital reduction. It shall be the higher of the two calculations and the price shall not be less than 80% of the reference price.

1. The reasonableness of the private placement pricing: The Company intends to authorize the Board to determine the actual issuance price that is not lower than the ratio resolved by the shareholders' meeting based on the regulatory requirements, subject to the subsequent negotiations with specific persons, market conditions and the prospect of the Company. The basis of the establishment of the private placement price above complies with the regulatory requirements of the competent authority; meanwhile, considering that the transfer point of time, targets and quantity of the securities under the private placement are strictly restricted, the prohibition for listing within three years, the unfavorable liquidity and other factors, the establishment of the ratio of the private placement price shall be reasonable.

(II) The method for selecting the specific persons

1. The targets of fundraising through the issuance of securities are limited to specific persons stated in Article 43-6 of the Securities and Exchange Act, pursuant to Letter Jin-Guan-Zheng-Fa No. 11203832209 issued by the Financial Supervisory Commission on September 12, 2023.

2. If the places are strategic investors: The Company will select operators, either individuals or corporations, who have the considerable understandings of the Company's operations that are

beneficial to the future of the Company to assist the Company in improving its technologies and quality, reducing costs, and increasing its efficacy through their own experiences, technologies, brands or channels. To optimize the Company's financial structure and reinforce its solvency, the introduction of capital from places may improve the overall financial nature of the Company; furthermore, the participation of places reduces the immense capital costs, improves the financial structure of the Company, and minimizes the operating risks. The Company intends to authorize the Board to review the relevant qualifications of strategic investors.

1. If places are insiders or related parties of the Company: Not applicable.

2. There is no confirmed place at present; the Company intends to authorize the Board to determine the confirmed places.

(III) The reasons for the necessity of conducting the private placement

1. The reasons for not adopting a public offering: Considering the timeliness, convenience and issuance costs for fundraising, the Company intends to perform the capital increase in cash by way of private placement.

2. Usage of proceeds from the private placement of securities and the estimated effects to be achieved: The Company intends to authorize the Board to carry out the placement in no more than three batches within one year from the day on which the shareholders' meeting made the resolution. Proceeds from each batch of the private placement are used to enrich our working capital, reinvestments, or other capital requirements, in response to future development to achieve the effects of capital cost reduction, competitiveness reinforcement, and operating efficacy improvement.

III. The rights and obligations of securities under the private placement are equivalent to the issued shares, and such shares shall not be transferred within three years from the delivery date, except for transferring counterparties stated in Article 43-8 of the Securities and Exchange Act; after three years from the delivery date, the Company intends to propose to the shareholders' meeting to authorize the Board to apply for the listing of the securities under the private placement for trading with the competent authority according to the relevant laws and regulations.
