Message from the Chairman Annual Report 2020  Expressway Authority of Thailand of the Board of Directors of Expressway Authority of Thailand   In 2020, Expressway Authority of Thailand starts alternation to secure progressiveness supported by the government, Ministry of Transport, the public at large and travelers. Thereby, we can transform to be “the happy Expressway.” So far, we have witnessed happiness and smiles among our travelers for free traveling during the public holidays and long weekend allowed for them by the government, the Ministry of Transport (MOT) and all of us, the personnel of Expressway Authority of Thailand. Moreover, during the critical COVID-19 situation we also participate with all government agencies to promote social activities for mask given to our officials and employees, passengers including donation to medical and charity organizations and personnel. This specifically identifies our intention to be real partnership with all Thai people. We also prepare and develop our organization toward the cashless society plus new models of EASY PASS services to increase more effective approaches. More importantly, we are now in the era to introduce how technical approach and innovation can permanently solve the facing problems at tollgates leading to the M-Flow system development jointly with our partners who provide Motor Ways and Concession highways as a mean to study and try the Multi-Lane Free Flow. Then we will top up by integration with the available information from the Department of Land Transportation (DLT) toward possible payment by the car registration signs to enable traffic convenience and reduce wasteful energy consumption caused by traffic getting stuck at the tollgate permanently. Accordingly, the Organization shall handle personnel welfare plans alongside the aforementioned innovation focusing on how to ensure resource contribution as well as skillful ability to promote and maintain environmental safety and friendliness while developing efficiency of the EXAT Network to better serve the travelers in the future. Therefore, collaboration from all relevant sectors is the factor to drive and create our organization toward well recognition for both the outcomes and excellent people caretaking.

Personnel Development Expressway Authority of Thailand (EXAT) pays attention to personnel development or improvement of our employee capacity at all levels based on the personnel development plan under the EXAT’s strategies and the three personnel capabilities namely Core Competency, Functional Competency and Managerial Competency as well as the Training Roadmap and the Individual Development Plan (IDP). Accordingly, we mainly focus on the main capacity of our organization while preparing for the upgrade retirement and specific changes facing. In the 2020 financial year followings are the important annual personnel development plans. 1) Knowledge, skills and capacity development for executives and personnels at all levels to ensure professional performance and readiness to welcome the digital era. 2) Personnel development toward righteousness, ethical conducts and good governance. 3) Promote various learning processes and approaches while systematically and continuously promote the organization’s culture. 4) Promote organization’s knowledge management alongside working innovation. 5) Develop information technology system, support internal personnel development and learning. 6) Personnel development based on “work life balance” to improve the employee’s working life. For the 2020 budget year, EXAT organizes 48 trainings, seminars and site visits for executives and employees apart from the those external trainings with both the public and private sectors. Moreover, employees have been provided the advance education at the master’s and doctoral degrees.

Code of Ethics Practice by Annual Report 2020  Expressway Authority of Thailand Expressway Authority of Thailand Code of Ethics identifies all rules of professional conducts committed by the EXAT’s employees to maintain and promote their honor and status while upholding their mindset for righteousness and ethical conduct. “Ethical conduct” composes of morality and doctrine whereas “morality” refers to any or certain appropriate conducts. “Doctrine,” Moreover, is of various meanings i.e. goodness, religious teaching, conduct principles etc. Thereby the meaning given by the two combined terms of “ethical conduct” directly means “principles of conducts” or “ways of conducts.” Accordingly, EXAT refers to Ethical Conduct as behavioral principles among all employees based on honesty and accuracy toward the organization and all stakeholders as well as the public at large and the society aiming to achieve the highest goal as being the leading state enterprise of the country. Apparently “ethical conduct” or “code of ethics” shares the same goal toward good practices by various persons or organizations either for oneself and the others. It is the practice with proper reasoning and consideration with the high consciousness. EXAT, with our main responsibility to solve the traffic problems in Bangkok Metropolitan Area (BMA) including various transportation lines leading toward development of the logistic system internally through the good governance approach, we, therefore, determine to establish realization of good governance among our employees with well recognition and trust by relevant stakeholders and the public at large. In order to achieve the aforementioned goal, all EXAT employees must enhance the well outcomes to ensure that all relevant stakeholders, service users and people at large are well aware of the code of conduct strictly followed by all EXAT’s officials and employees. As of the 2011 budgeting year EXAT recompiled the organization’s code of conduct with wordings that communicate how their employees seriously follow the established ethical principles for which it is of the “HEARTS” abbreviation meaning that “working with one’s heart.” HEARTS Determination to “work with one’s heart” comprises of the following principles which shall be holding by all working staff. HE A R T S Honesty Equity/Equitable Accuracy Responsibility Transparency Society Treatment “Accuracy, Honesty, Equity, Responsibility, Transparency, Society” Thereby, EXAT recompiles its Code of Conduct for the modern era requirement approved by the EXAT Board in the 4/2018 meeting organized on 25 April 2018. 37

EXAT’s Corporate Governance Reinforcement Guidelines Good Corporate Governance Policy Expressway Authority of Thailand’s main operating objectives are to alleviate traffic congestion problem in the zone of the Bangkok Metropolitan Region in order to reduce national economic loss and perform its business for financial stability and sustainable growth. Efficient management and good corporate governance are considered crucial to achieve such objectives.

EXAT’s Board of Directors acknowledged this policy in the meeting No. 6/2010 on June 28, 2010. Summary of EXAT’s Corporate Governance Independent Director in EXAT’s Board of Directors In the meeting No. 8/2003 on July 30, 2003, EXAT’s Board of Directors resolved to approve the definition of “independence” of the director of EXAT’s Board of Directors as follows. “Independence” of EXAT’s director means the independence of the external directors, e.g. qualified persons from the private sector, independent organization or educational institution, to exercise his/her own discretion for decision, make a real independent action and to be able to change or restrain directly any actions when it is deemed necessary. He/she must not have any business relationships, expectation of benefit or any other relationship, including either direct or indirect interest, with executives of the affiliated state- owned enterprise, ministries, agencies or companies concerned. In the fiscal year 2020, the EXAT’s Board of Directors consisted of four qualified members, as follows : 1. Rear Admiral Suvin Jangyodsuk 3. Ms. Trithip Sivakriskul 2. Mrs. Phongsaward Guyaroonsuith 4. Asst. Prof. Boonchai Sowanwanichakul 38

Performance of the Independent Board of Directors Annual Report 2020  Expressway Authority of Thailand At the meeting, 1/2020 of the Independent Board on July 16, 2020, has passed a resolution requiring EXAT to propose the report of the Meeting No. 1/2020 of the Independent Board on July 16, 2020 to the EXAT’s Board of Directors for consideration. At the meeting No. 12/2020 of the EXAT’s Board of Directors on September 14, 2020, it resolved approval for EXAT continuing perform as follows : 1. The organization of EXAT Resolution : 1) Accelerate the creation of leadership project for middle-level executives and above to change the way of thinking (mindset) of executives who will grow to be high-level executives in the future to be omniscien, knowledgeable in work, confident in the correctness of operations, dare to think, dare to decide, dare to take responsibility to create a new generation of executives that will gradually lead to branding and changing EXAT to be a modern organization. 2) Accelerate EXAT’s executives and employees’ unity by creating employees’ participation in many areas to achieve unity and join forces together to complete the work. These include listening to the voice from lower-level employees to know their opinions, and the EXAT’s Governor can discuss EXAT’s operations with all Deputy Governors to go together in the same story and reflect the concept of operation down to the lower-level employees to share in the same direction and unity. 3) Accelerate and strengthen the Deputy Governor’s competency to be smart and knowledgeable to be able to manage the work of EXAT, which is a large organization with strength, which may increase training or allow specialists to assist coaching in certain areas. 4) Expedite methods or projects that will help develop and complement the executives who will grow up at each level. 2. The role of the EXAT’s Board of Directors and the organization Resolution : EXAT must accelerate the organization’s strength and unity for content and methods for presenting the meeting agenda to the EXAT’s Board of Directors for consideration. If the organization is strong and has a body of knowledge presented, it will answer questions and clarify in all areas for the Board’s consideration. When the organization is strong, it will have a position to present and explain and give the directors reasons to make the presentation successful. In this regard, the EXAT’s Board of Directors has a role and duty to direct the policy and set the operational direction, driven by the EXAT’s Governor, will not go into details of the organization’s operations. For example, at present, agencies in EXAT presents the EXAT’s Board of Directors meeting’s agenda, which is the subject of details of EXAT’s operations that should be discussed to reach a unified resolution. But agencies in EXAT still brought the said matter to the EXAT’s Board of Directors meeting for approval instead. Therefore, the EXAT Board of Directors has to consider work that is too detailed, which should not be so. If the organization operates regularly, it can cause the organization to fail. Therefore, the organization should be strengthened to be a coalition that drives the operations parallel with the EXAT Board of Directors’ supervision. 3. CG of the agency for procurement Resolution : EXAT must emphasize and improve the CG of the procurement department to have better work efficiency by improving the procurement process from the process of issuing various requirements, such as the draft scope of work (TOR), etc., to be thorough and complete correctly. EXAT had many procurement risks in the past, which may arise from misunderstandings or communication and coordination between internal and external departments. This causes the procurement process to be delayed and time- consuming, congested in many areas, and affecting employees’ trust and the corporate image. Respect for Stakeholders’ Interest EXAT has operated by considering stakeholder impacts. Based on the preliminary study of stakeholders in terms of consequential relations by groups of influence and of concern and by social and environmental responsibility, the stakeholders are categorized and prioritized into seven main groups, namely expressway users, the government sector as owner, EXAT’s employees, people affected by land expropriation, business 39

partners, communities surrounding exclusive right of way and society. EXAT has established the policy for equitable and impartial treatment of the stakeholders and the rights of all stakeholder groups have been taken into consideration as well. Information Disclosure and Transparency EXAT foresees the importance of information disclosure of information and operating transparency due to the significance of information for decision making of all internal and external related parties as well as evaluation of organizational efficiency. Based on equitable treatment, EXAT provides appropriate, accurate, reliable and up-to-date financial and non-financial information to stakeholders through various channels such as annual report, Internet, Intranet, EXAT Call Center and internal & external public relations activities via media. Information disclosure under the Official Information Act B.E. 2540 (1997) is also carried out. The building of EXAT’s Information Center was constructed in 2011 to facilitate the service users. In addition, EXAT has monitored and assessed the internal control and risk management and proposed the assessment result to the executives and the Risk Management Committee for approval before submitting to the Board of Directors for acknowledgement on schedule. Ethics and Morality Promotion EXAT organizes trainings/seminars/activities to promote morality and ethics among its employees and disseminates knowledge of the Ethics Guidelines, e.g. OJT Tour : HEARTS to HEART, EXAT CG Day, quiz contest on good corporate governance and EXAT’s practical ethics, creation of Facebook Fanpage EXAT CG, etc. In addition, all employees have been designated to annually prepare reports on conflict of interest to the governor, or in case of either newly appointed or where conflict of interest occurs during the year. From October 2019 to September 2020, no conflict of interest committed by EXAT’s employees was found. Corporate Governance Monitoring and Evaluation The State Enterprise Policy Office (SEPO), Ministry of Finance, had a policy whereby the EXAT shall adopt the State Enterprise Assessment Model (SEAM) to evaluate its performance, with good corporate governance and organizational leadership as part of the evaluation of core business enablers. To achieve such evaluation criteria, EXAT has carried out in compliance with the procedure of Deming Cycle. Good corporate governance annual plan has been established in accordance with SEPO’s Principles and Guidelines on Corporate Governance of State-Owned Enterprise 2019 by applying the seven principles of international corporate governance (CG) standard, namely Accountability, Responsibility, Equitable Treatment, Transparency, Value Creation, Ethics and Participation to the nine plans consisting of : 1) Government sector’s roles 2) Rights and equity of shareholders 3) The Board of Directors 4) Roles of stakeholders 5) Sustainability and innovation 6) Information disclosure 7) Risk management and internal control 8) Code of ethics 9) Performance monitoring EXAT has determined that the said plan is implemented (Do) whereas CG implementation in all eight sections are monitored and the result of CG performance is collected (Check) ; and the result of each section is analyzed and evaluated for further improvement (Act). EXAT presented the result of the CG performance to the quarterly meetings of Corporate Governance Sub-committee and EXAT’s Board of Directors for acknowledgement. Corporate Governance Information EXAT has communicated the corporate governance policy and guidelines to the Board of Directors and employees for acknowledgement and observance. Other news information relating to good corporate governance has been publicized through publication media such as circulation, posting a notice at EXAT’s office buildings, EXAT Sound, publication leaflets, internal and external magazines, Digital Signage, Roll up, Internet and Intranet. EXAT has also occasionally emphasized on the meetings, trainings and seminars, and activities, etc. The general public can access the said information from EXAT’s annual report and information channel. 40
