Supplier Code of Conduct

Supplier Code of Conduct Revised Jan 24, 2022 Version 7.0 Preface Sunol Tech Inc. and its subsidiaries (“Sunol Tech”) strive to operate in a responsible manner, reduce and mitigate risk, and improve continuously. The way we conduct business is as important as the products and services weprovide. Accordingly, Sunol Tech will only do business with suppliers, contractors, and consultants (collectively “Suppliers”) who comply with applicable laws, rules, and regulations(collectively “applicable laws”) and commit to our standards of business conduct, as set forthin this Supplier Code of Conduct (“Code”). Sunol Tech expects that Suppliers, their employees, sub-suppliers and any other parties involved with the execution of Sunol Tech work, similarly comply with applicable laws and commit to the standards set forth in this Code. The Responsible Business Alliance (RBA), formerly the Electronic Industry Citizenship Coalition (EICC), Code of Conduct establishes standards to ensure that working conditions in the electronics industry, or industries in which electronics are a key component, and its supply chains are safe, that workers are treated with respect and dignity, and that business operations are environmentally responsible and conducted ethically. Sunol Tech has adapted RBA’s latest Code of Conduct, Version 7.0 to create this Code for Sunol Tech’s supply chain. Sunol Tech’s Suppliers (“Suppliers”) should regard the Code as a total supply chain initiative. Suppliers are encouraged to require its next tier suppliers to acknowledge and implement the Code. Fundamental to adhering to the Code is the understanding that a business, in all of its activities, must operate in full compliance with the laws, rules, and regulations of the countries in which it operates. 1 The Code also encourages Suppliers to go beyond legal compliance, drawing upon internationally recognized standards, in order to advance social and environmental responsibility and business ethics. In no case can complying with the Code violate local laws. Ifthere are differing standards between this Code and local law, Sunol Tech defines conformance as meeting the strictest requirements. In alignment with the UN Guiding Principles on Business and Human Rights, the provisions in this Code are derived from and respect internationally recognized standards including the ILO Declaration on Fundamental Principles and Rights at Work and the UN Universal Declaration of Human Rights. Sunol Tech is committed to obtaining regular input from stakeholders in the continued development and implementation of the Code. We encourage stakeholders to provide input. The Code is made up of five sections. Sections A, B, and C outline standards for Labor, Health and Safety, and the Environment, respectively. Section D adds standards relating to business ethics. Section E outlines the elements of an acceptable system to manage conformity to this Code. We appreciate our Suppliers’ commitment to responsible business practices. _____________________________________________________________________________________

1 The Code is not intended to create new and additional third-party rights, including forworkers. A. LABOR Suppliers are committed to uphold the human rights of workers, and to treat them with dignity and respect as understood by the international community. This applies to all workers including temporary, migrant, student, contract, direct employees, and any other type of worker. The recognized standards, as set out in the References, were used in preparing the Code and may be useful sources of additional information. The labor standards are:

1) Freely Chosen Employment Forced, bonded (including debt bondage) or indentured labor, involuntary or exploitative prison labor, slavery or trafficking of persons is not permitted. This includes transporting, harboring, recruiting, transferring, or receiving persons by means of threat, force, coercion, abduction or fraud for labor or services. There shall be no unreasonable restrictions on workers’ freedom of movement in the facility in addition to unreasonable restrictions on entering or exiting companyprovided facilities including, if applicable, workers’ dormitories or living quarters. As part of the hiring process, all workers must be provided with a written employment agreement in their native language that contains a description of terms and conditions of employment. Foreign migrant workers must receive the employment agreement prior to the worker departing from his or her country of origin and there shall be no substitution or change(s) allowed in the employment agreement upon arrival in the receiving country unless these changes are made to meet local law and provide equal or better terms. All work must be voluntary, and workers shall be free to leave work at any time or terminate their employment without penalty if reasonable notice is given as per worker’s contract. Employers, agents, and sub-agents’ may not hold or otherwise destroy, conceal, or confiscate identity or immigration documents, such as government-issued identification, passports, or work permits. Employers can only hold documentation if such holdings are required by law. In this case, at no time should workers be denied access to their documents. Workers shall not be required to pay employers’ agents or sub-agents’ recruitment fees or other related fees for their employment. If any such fees are found to have been paid by workers, such fees shall be repaid to the worker.

2) Young Workers Child labor is not to be used in any stage of manufacturing. The term “child” refers to any person under the age of 15, or under the age for completing compulsory education, or under the minimum age for employment in the country, whichever is greatest. Suppliers shall implementan appropriate mechanism to verify the age of workers. The use of legitimate workplace learning programs, which comply with all laws and regulations, is supported. Workers under the age of 18 (Young Workers) shall not perform work that is likely to jeopardize their health or safety, including night shifts and overtime. Suppliers shall ensure proper management of student workers through proper maintenance of student records, rigorous due diligence of educational partners, and protection of students’ rights in accordance with applicable laws and regulations. Suppliers shall provide appropriate support and training to all student workers. In the absence of local law, the wage rate for student workers, interns, and apprentices shall be at least the same wage rate as other entry-level workers performing equal or similar tasks. If child labor is identified, assistance/remediation is provided.

3) Working Hours Studies of business practices clearly link worker strain to reduced productivity, increased turnover, and increased injury and illness. Working hours are not to exceed the maximum set by local law. Further, a workweek should not be more than 60 hours per week, including overtime, except in emergency or unusual situations. All overtime must be voluntary. Workers shall be allowed at least one day off every seven days.

4) Wages and Benefits Compensation paid to workers shall comply with all applicable wage laws, including those relating to minimum wages, overtime hours and legally mandated benefits. In compliance with local laws, workers shall be compensated for overtime at pay rates greater than regular hourly rates. Deductions from wages as a disciplinary measure shall not be permitted. For each pay period, workers shall be provided with a timely and understandable wage statement that includes sufficient information to verify accurate compensation for work performed. All use of temporary, dispatch and outsourced labor will be within the limits of the local law.

5) Humane Treatment There is to be no harsh or inhumane treatment including violence, gender-based violence, sexual harassment, sexual abuse, corporal punishment, mental or physical coercion, bullying, public shaming, or verbal abuse of workers; nor is there to be the threat of any such treatment. Disciplinary policies and procedures in support of these requirements shall be clearly defined and communicated to workers.

6) Non-Discrimination/Non-Harassment Suppliers should be committed to a workplace free of harassment and unlawful discrimination. Companies shall not engage in discrimination or harassment based on race, color, age, gender, sexual orientation, gender identity and expression, ethnicity or national origin, disability, pregnancy, religion, political affiliation, union membership, covered veteran status, protected genetic information or marital status in hiring and employment practices suchas wages, promotions, rewards, and access to training. Workers shall be provided with reasonable accommodation for religious practices. In addition, workers or potential workers should not be subjected to medical tests, including pregnancy or virginity tests, or physical exams that could be used in a discriminatory way. This was drafted in consideration of ILO Discrimination (Employment and Occupation) Convention (No.111).

7) Freedom of Association In conformance with local law, Suppliers shall respect the right of all workers to form and join trade unions of their own choosing, to bargain collectively, and to engage in peaceful assembly as well as respect the right of workers to refrain from such activities. Workers and/or their representatives shall be able to openly communicate and share ideas and concerns with management regarding working conditions and management practices without fear of discrimination, reprisal, intimidation, or harassment.

B. HEALTH AND SAFETY Suppliers recognize that in addition to minimizing the incidence of work-related injury and illness, a safe and healthy work environment enhances the quality of products and services, consistency of production and worker retention and morale. Suppliers also recognize that ongoing worker input and education are essential to identifying and solving health and safety issues in the workplace. Recognized management systems such as ISO 45001 and ILO Guidelines on Occupational Safety and Health were used as references in preparing the Code and may be useful sources of additional information. The health and safety standards are:

1) Occupational Safety Worker potential for exposure to health and safety hazards (chemical, electrical and other energy sources, fire, vehicles, and fall hazards, etc.) are to be identified and assessed, mitigated using the Hierarchy of Controls, which includes eliminating the hazard, substituting processes or materials, controlling through proper design, implementing engineering and administrative controls, preventative maintenance and safe work procedures (including lockout/tagout), and providing ongoing occupational health and safety training. Where hazards cannot be adequately controlled by these means, workers are to be provided with appropriate, well-maintained, personal protective equipment, and educational materials about risks to them associated with these hazards. Reasonable steps must also be taken to remove pregnant women and ‘nursing mothers from working conditions with high hazards, remove or reduce any workplace health and safety risks to pregnant women and nursing mothers, including those associated with their work assignments, and provide reasonable accommodations for nursing mothers.

2) Emergency Preparedness Potential emergency situations and events are to be identified and assessed, and their impact minimized by implementing emergency plans and response procedures including emergency reporting, employee notification and evacuation procedures, worker training, and drills. Emergency drills must be executed at least annually or as required by local law, whichever is more stringent. Emergency plans should also include appropriate fire detection and suppression equipment, clear and unobstructed egress, adequate exit facilities, contact information for emergency responders, and recovery plans. Such plans and procedures shall focus on minimizing harm to life, the environment, and property. 3) Occupational Injury and Illness Procedures and systems are to be in place to prevent, manage, track and report occupational injury and illness, including provisions to encourage worker reporting, classify and record injury and illness cases, provide necessary medical treatment, investigate cases and implement corrective actions to eliminate their causes, and facilitate the return of workers to work. 4) Industrial Hygiene Worker exposure to chemical, biological, and physical agents is to be identified, evaluated, and controlled according to the Hierarchy of Controls. If any potential hazards were identified, Suppliers shall look for opportunities to eliminate and/or reduce the potential hazards. If elimination or reduction of the hazards is not feasible, potential hazards are to be controlled through proper design, engineering, and administrative controls. When hazards cannot be adequately controlled by such means, workers are to be provided with and use appropriate, well-maintained, personal protective equipment free of charge. Protective programs shall be ongoing and include educational materials about the risks associated with these hazards. 5) Physically Demanding Work Worker exposure to the hazards of physically demanding tasks, including manual material handling and heavy or repetitive lifting, prolonged standing, and highly repetitive or forceful assembly tasks is to be identified, evaluated, and controlled.

6) Machine Safeguarding Production and other machinery shall be evaluated for safety hazards. Physical guards, interlocks, and barriers are to be provided and properly maintained where machinery presents an injury hazard to workers. 7) Sanitation, Food, and Housing Workers are to be provided with ready access to clean toilet facilities, potable water and sanitary food preparation, storage, and eating facilities. Worker dormitories provided by the Supplier or a labor agent are to be maintained to be clean and safe, and provided with appropriate emergency egress, hot water for bathing and showering, adequate lighting and heat and ventilation, individually secured accommodations for storing personal and valuable items, and reasonable personal space along with reasonable entry and exit privileges. 8) Health and Safety Communication Suppliers shall provide workers with appropriate workplace health and safety information and training in the language of the worker or in a language the worker can understand for all identified workplace hazards that workers are exposed to, including but not limited to mechanical, electrical, chemical, fire, and physical hazards. Health and safety related information shall be clearly posted in the facility or placed in a location identifiable and accessible by workers. Training is provided to all workers prior to the beginning of work and regularly thereafter. Workers shall be encouraged to raise any health and safety concerns without retaliation.

C. ENVIRONMENT Suppliers recognize that environmental responsibility is integral to producing world-class products. Suppliers shall identify the environmental impacts and minimize adverse effects on the community, environment, and natural resources within their manufacturing operations, while safeguarding the health and safety of the public. Recognized management systems such as ISO 14001 and the Eco Management and Audit System (EMAS) were used as references in preparing the Code and may be a useful source of additional information. The environmental standards are: 1) Environmental Permits and Reporting All required environmental permits (e.g. discharge monitoring), approvals, and registrations are to be obtained, maintained, and kept current and their operational and reporting requirements are to be followed. 2) Pollution Prevention and Resource Reduction Emissions and discharges of pollutants and generation of waste are to be minimized or eliminated at the source or by practices such as adding pollution control equipment; modifying production, maintenance, and facility processes; or by other means. The use of natural resources, including water, fossil fuels, minerals, and virgin forest products, is to be conserved by practices such as modifying production, maintenance and facility processes, materials substitution, re-use, conservation, recycling, or other means.

3) Hazardous Substances Chemicals, waste, and other materials posing a hazard to humans or the environment are to be identified, labeled, and managed to ensure their safe handling, movement, storage, use, recycling or reuse, and disposal.

Ozonedepleting substances are to be effectively managed in accordance with the Montreal Protocol and applicable regulations. Suppliers shall conduct routine monitoring of the performance of its air emission control systems.

6) Materials Restrictions Suppliers are to adhere to all applicable laws, regulations, and customer requirements regarding the prohibition or restriction of specific substances in products and manufacturing, including labeling for recycling and disposal.

7) Water Management Suppliers shall implement a water management program that documents, characterizes, and monitors water sources, use and discharge; seeks opportunities to conserve water; and controls channels of contamination. All wastewater is to be characterized, monitored, controlled, and treated as required prior to discharge or disposal. Suppliers shall conduct routine monitoring of the performance of its wastewater treatment and containment systems to ensure optimal performance and regulatory compliance.

8) Energy Consumption and Greenhouse Gas Emissions Suppliers are to establish a corporate-wide greenhouse gas reduction goal. Energy consumption and all relevant Scopes 1 and 2 greenhouse gas emissions are to be tracked, documented, and publicly reported against the greenhouse gas reduction goal. Suppliers are to look for methods to improve energy efficiency and to minimize their energy consumptionand greenhouse gas emissions.

D. ETHICS To meet social responsibilities and to achieve success in the marketplace, Suppliers and their agents are to uphold the highest standards of ethics including:
