The General Assembly Chairman shall be elected by the Company’s shareholders as set forth by the Regulation on the Principles and Procedures for General Assembly Meetings of Joint Stock Companies and the Representatives of the Ministry Attending Such Meetings (the “Regulation”) issued under the Turkish Commercial Code No: 6102 (the “TCC”), as well as the Articles of Association and the Internal Directive on the Working Principles of the General Assembly of the Company. Once the General Assembly Chairman is elected by the Company’s shareholders, the Chairman shall appoint the Minutes Clerk and Vote Collector.

2.	Authorization of the General Assembly Meeting Chairman to sign the minutes of the meeting

The Company’s shareholders attending the General Assembly shall vote to authorize the General Assembly Chairmanship to sign the minutes of the General Assembly.

3.	Discussion of increasing the Company’s current total share capital and matters of pre-emptive rights as per Article 461/2 of the TCC and amendment of Article 6 of the Company’s Articles of Association titled “Capital” as set forth in the “New Text”

The Company’s shareholders shall vote to amend Article 6 titled “Capital” of the Company’s Articles of Association to increase the share capital in an aggregate amount of TRY 9,321,419,250.00 of which TRY 14,285,700.00 shall be allocated to the nominal value of the newly issued shares and the remaining TRY 9,307,133,550.00 shall be allocated to the share premium.

According to the new text of Article 6, the nominal share capital of the Company shall be increased from TRY 72,368,116.80, divided into 361,840,584 shares each with a nominal value of TRY 0.20 (20 Kuruş), to TRY 86,653,816.80, divided into 433,269,084 shares each with a nominal value of TRY 0.20 (20 Kuruş).
