(2) Buyer's sale-request (call) option 1) The "issuing company" has the right (the "call option") to request that the subscriber sell to the "issuing company" or a third party designated by the "issuing company" (the "buyer") 30/100 of the total face value of "this bond" subscribed by the subscriber under the bond subscription agreement (the "convertible bonds subject to the call option"), on each date falling every three months from the date one year after the issue date of "this bond" until the date two years after issuance (or, if not a business day, the next business day) (the "call option exercise date"). If the buyer is the largest shareholder or a person specially related to the largest shareholder (the "largest shareholder, etc."), the quantity of this bond each largest shareholder, etc. may purchase is limited to the extent set forth in Article 5-21(3) of the "Regulation on Issuance and Disclosure of Securities," based on the shareholding ratio as of the bond subscription agreement date at issuance. The subscriber also bears the obligation to comply with a sale request for 30/100 of the total amount of "this bond" subscribed under this agreement. 2) If the buyer wishes to exercise this call option, the buyer must notify the subscriber in writing (the "call option exercise notice") within the call option exercise period below, and the resulting sale and purchase agreement is deemed concluded when the buyer's call option request reaches the bondholder. 3) Call option exercise schedule and purchase price: the total face value of the bonds subject to the call option, plus an amount calculated on a pro-rata monthly basis applying an annual rate of 3.0% (semi-annual compounding) from the bond issue date to the purchase price payment date below, plus any unpaid coupon interest calculated on a pro-rata monthly basis since the last interest payment date. If the payment date is not a business day, redemption will be made on the next business day with no interest accruing after the principal repayment date. No. 1, purchase price payment date 2024-09-20; exercise period 2024-08-07 to 2024-08-20; purchase amount 103.0225% of face value. No. 2, purchase price payment date 2024-12-20; exercise period 2024-11-07 to 2024-11-20; purchase amount 103.7952% of face value. No. 3, purchase price payment date 2025-03-20; exercise period 2025-02-07 to 2025-02-20; purchase amount 104.5678% of face value. No. 4, purchase price payment date 2025-06-20; exercise period 2025-05-07 to 2025-05-20; purchase amount 105.3521% of face value. No. 5, purchase price payment date 2025-09-20; exercise period 2025-08-07 to 2025-08-20; purchase amount 106.1364% of face value. 4) Default interest: if the issuing company fails to pay principal or interest by each due date under Article 1(3) of this agreement, default interest is payable on such principal and interest, applying an annual compound interest rate of 15% for the period from the day after the payment due date to the date of actual payment, calculated daily on a 365-day-year basis. 5) Payment and delivery of the bond: the buyer shall pay the purchase price to the subscriber on the purchase price payment date in the manner designated by the subscriber, and the subscriber shall deliver the bonds subject to the call option to the buyer by electronically registering them in the buyer's electronic registration account under the "Act on Electronic Registration of Stocks, Bonds, etc." 6) Mandatory holding: to guarantee exercise of the call option, the subscriber must hold, in unconverted form, 30/100 of the subscription amount at issuance under Article 2 of this agreement until the end of the call option exercise period (September 20, 2025). However, regardless of this mandatory holding amount, if the issuing company's obligations become immediately due and payable under Article 3(22) of this agreement with respect to 100% of the bond subscription amount, the bondholder is not obligated to guarantee the buyer's exercise of the call option, and this agreement loses effect. 7) If this call option and the "early redemption right" under Article 3(23) of this agreement are exercised simultaneously, the early redemption right has priority. 8) Guarantee of call-option exercise and exemption upon transfer: if the bondholder transfers this bond to a third party, it must be done in a manner that guarantees the exercise of the call option and the mandatory holding requirement, and to the extent transferred, the bondholder's obligations under this agreement are deemed extinguished.
