GUIDELINES FOR THE CONDUCT OF OFFICERS AND EMPLOYEES

Article 42 (Prohibition of Insider Trading)

(1) The Company shall prohibit insider trading.

(2) The Chief Accounting Officer shall ensure that all employees are made aware that insider trading is both illegal and unethical. In this regard, the Chief Accounting Officer shall provide training to employees to ensure compliance with the following:

No employee, regardless of position, shall directly or indirectly engage in the trading of the Company’s securities or securities related to the Company’s business by using material non-public information relating to the Company acquired in the course of performing his or her duties. Such acts are prohibited under applicable laws and Company policies. Material non-public information must not be disclosed to any person outside the Company until it is lawfully disclosed through appropriate procedures.

Employees, including the Chief Accounting Officer, shall be prohibited from engaging in short-term trading (e.g., options trading, short-swing profits, or same-day transactions) of the Company’s securities. In addition, short selling of the Company’s securities by employees, including the Chief Accounting Officer, shall be prohibited.

For the purposes of this Article, “material information” shall mean any information that a reasonable investor would consider important when deciding whether to purchase, hold, or sell securities.

(3) The Chief Accounting Officer shall take necessary measures to ensure that any request for information from the media is handled exclusively by the Public Relations Office or other departments designated in advance depending on the nature of the inquiry, in order to control the leakage of non-public information and to ensure professional handling of such matters.
