(2) Upon the issuing company's IPO, the issuing company shall, to the extent permitted by applicable law or listing authorities, give priority in the secondary offering to shares acquired by the investor (including shares converted into common stock through conversion of these new shares); provided that if the issuing company pursues a backdoor listing (SPAC merger) by merging with an unlisted company after the IPO, application of this clause shall be separately discussed. (3) If an IPO is reasonably determined to be feasible, the parties shall mutually consult and proceed with the necessary IPO procedures.

- Matters concerning conversion price adjustment: Article 8 (Conversion) of the Redeemable Convertible Preferred Stock Investment Agreement (3) The conversion ratio and conversion price adjustment of these class shares shall be governed by the following: 1. The conversion ratio of these class shares into common stock is the number determined by dividing the issue price per share of these class shares by the conversion price in effect at the time of conversion; the initial conversion ratio is 1 common share per 1 class share. The initial conversion price for the common stock to be issued upon conversion of these class shares is KRW 1,993,461, the issue price per share of these class shares. 2. If the issuing company conducts a rights offering at an issue price below the conversion price of these class shares (meaning, if adjusted under this paragraph, the conversion price as adjusted; and in this item, referring to the conversion price or exercise price where common stock is issued upon a conversion request for convertible bonds, convertible preferred stock, redeemable convertible preferred stock, or bonds with warrants, or upon exercise of warrants), or issues warrants or equity-linked securities with attached warrants or conversion rights, the conversion price shall be adjusted to that lower issue price per share. The conversion price adjustment date for this reason shall be the issuance date of the relevant shares, etc. 3. If, before a conversion request, there is a merger, division or spin-off merger, stock split or consolidation, capital reduction, or transfer of the entire business, the conversion price shall be adjusted to a conversion price that would allow conversion into the number of shares the preferred shareholder could have held had the conversion right been exercised and fully converted into common stock immediately before the adjustment event. The conversion price adjustment date for this reason shall be the effective date of the merger, division or spin-off merger, stock split or consolidation, capital reduction, or business transfer. 4. If, before a conversion request, the issuing company issues shares through a bonus issue or stock dividend, the conversion price shall be adjusted as follows. The conversion price adjustment date for this reason shall be the record date of the bonus issue or stock dividend. Adjusted conversion price = conversion price before adjustment x total shares issued before / (total shares issued before + total new shares issued through the bonus issue or stock dividend) 5. If the issuing company has no sales performance in the new semiconductor business it is pursuing within 1 year from the closing date, the conversion price of these class shares (meaning, if a conversion price adjustment under items 1-4 of this paragraph occurred before this event, the conversion price as so adjusted) shall be adjusted to 70% of that price; provided that delays due to force majeure such as war, epidemic, or natural disaster not attributable to the issuing company are excepted. 6. If the issuing company's full-year 2028 EBITDA (the "benchmark performance") is less than KRW 10 billion, the conversion price of these class shares (meaning, if a conversion price adjustment under items 1-4 of this paragraph occurred before this event, the conversion price as so adjusted) shall be adjusted as follows; provided that the adjusted conversion price shall have a floor of KRW 1,395,423 per share (the per-share issue price of these class shares corresponding to 70% of the issuing company's pre-money valuation of KRW 50 billion), and this item does not apply if a conversion price adjustment under item 5 of this paragraph has occurred. However, if the issuing company attracts new investment with a pre-money valuation of KRW 70 billion or more for that follow-on investment, the issuing company and the holders of these class shares may consult on the specific application of the conversion price adjustment under this item, taking into account the terms of that follow-on investment. Adjusted conversion price = conversion price before adjustment x benchmark performance / KRW 10 billion 7. The issuing company shall notify the investor of the per-share indicative public offering price band to be stated in its IPO preliminary listing examination application no later than 5 business days before submitting that application; if 70% of the lower end of that indicative price band is below the conversion price of these class shares (meaning, if a conversion price adjustment under items 1-4 of this paragraph occurred before this event, the conversion price as so adjusted), the conversion price shall be adjusted to 70% of the lower end of the indicative public offering price band.
