1. Purpose of Green Procurement

The purpose of this guideline is to source eco-friendly parts and services from suppliers who are actively

involved in environmental conservation.

２．Scope of Application

These guidelines apply to all items and services procured by Nakayo, Inc. and delivered from suppliers, such

as raw materials, parts, packing materials, partially-completed products, fully-completed products, equipment

and tooling, secondary materials, writing materials, office and stationery supplies, office equipment, services

and logistics.

３．Investigation and agreement of environmental conservation for suppliers

To realize the purpose stated in the paragraph 1, Nakayo, Inc. requires suppliers to study and submit "Green

Procurement Survey for Suppliers", "Survey of Hazardous Chemical Substances", "Application for Change of

Production Condition of Purchased Product", "Hazardous Chemical Substances Inclusion Data (AIS and

MSDS Plus)" and "Non-Inclusion Certificate" and to conclude "Memorandum on Chemicals Contained in

Delivered Materials".

Information on the status of the suppliers' environmental activities and the status of environmental load

reduction of the procured products provided by suppliers is utilized to develop and design eco-friendly

products to deliver environmentally-compatible products to customers, as well as to support environmental

load-reducing activities as a part of the business activities of Nakayo, Inc. and suppliers.

3.1 Investigation of Suppliers As a condition for starting a new transaction, Nakayo, Inc. attaches importance to suppliers' "environmental conservation activities" and "status of the suppliers' environmental conservation for procured products" that we purchase from the suppliers. Our suppliers are encouraged to actively cooperate with us and satisfy the following guidelines.

(1) Items related to environmental activities of suppliers We will investigate and implement the status of our business partners' environmental conservation initiatives.

i). Already obtained environmental certification such as ISO 14001 certification or other equivalent

management system is in use.

・Verify the date of acquisition of ISO 14001 and certification authority.

ii). Green Procurement is implemented. iii). If any of the external certifications such as ISO 14001 has not been obtained, the following shall be

satisfied:

● Corporate philosophy and policy

① Have a corporate policy regarding environmental protection.

② Set environmental guidelines to ensure a continuous improvement and prevention of pollution.

③ The company's environmental policy commits to observe legal restrictions.

④ The company's environmental policy is known to all employees and available to any third party. ● Plan and organization

⑤ Assign specific organizations or persons to carry out relevant responsibilities toward the goal and target.

⑥ Have an implementation plan to achieve the goal and target.

⑦ Have a goal and target for environmental protection. ● Environment assessment / system

* Control and assess the following items in an effort for improvement:

⑧ Reduce water contamination.

⑨ Reduce air pollution

⑩ Reduce noise and vibration

⑪ Treat waste properly and reduce the amount of waste disposal.

⑫ Reduce energy consumption (electricity, gas, fuel, etc.)

⑬ We are working to reduce the burden on ecosystems and to appropriate the use of chemical substances.

⑭ Prohibit the use of hazardous chemical substances prohibited by Nakayo in the production line.

⑮ Have a product assessment program.

⑯ Have a systematic plan for emergency.

⑰ Have any internal environment audit program. ● Provision of education, training, and information

⑱ Implement an environmental education program.

⑲ Implement training for personnel engaged in work that may significantly affect the environment and have a list of such personnel.

⑳ Provide information related to environmental protection.

(2) Items related to the status of environmental load reduction of the procured products (raw materials, packing materials, parts, partially-completed products, fully-completed products)

With regard to the products that Nakayo procures from suppliers, suppliers are requested to participate in the investigation concerning the environmental load reduction items and information of hazardous chemical substances contained in products (product mass, contained hazardous chemical substances and density, usage application and usage site).

3.2 Environmental Impact Assessment

As for Nakayo's environmental aspects and the concept of environmental impact assessment, we evaluate the environmental aspects of input (input of energy, raw materials, etc.) and output (discharge of unnecessary materials such as waste and wastewater and products) associated with the production activities of our business partners, and the effects of these aspects on the environment. For evaluation, please investigate the presence or absence of use of laws and regulation substances that affect air pollution, water pollution, odors, ozone depletion, etc. at each business partner according to the request.

3.3 Investigation Related to Procured Products

(1) Investigation of chemical substances included in products For the procured production materials such as raw materials, parts, packing materials, partially-completed materials and fully-completed materials (including secondary materials such as paints and plating solution) which Nakayo adapts for the first time, suppliers are requested to investigate using chemSHERPA-AI or chemSHERPA-CI . Please break down to the level of raw materials for each part to submit the hazardous chemical substances inclusion data.

(2) Submission of Non-Inclusion Certificate

As a warranty supporting the Hazardous Chemical Substances Inclusion data in chemSHERPA –AI Or chemSHERPA -CI, suppliers are requested to submit “Non-Inclusion Certificate” (Figure 2).

ⅰ) Response to chemical substances subject to investigation and REACH

ⅰ-1) Investigation of hazardous chemical substances
