Introduction to OTH approach to green procurement
The 21st century is often referred to as the 'Century of the Environment' as many companies
including Orbray (Thailand) Co., Ltd. have agreed to implement environmental preservation
activities for the sake of future generations.
Our company is committed to the slogan "Sustainable development" and we place great
importance on certification; we obtained our ISO14001 certificate in December 2000.
We give careful consideration to providing best-in-class product quality at reasonable prices, always
taking into account the environmental aspect.
This guideline explains the basic concept of OTH's green procurement principles in order that
our company and our suppliers can achieve continual improvement.
Should there be any change in circumstances or any change in applicable legal or otherrequirements, the Green Procurement Guideline will be revised, and suppliers are expected tosubmit the environmental documents.
We look forward to your cooperation as our green partners.

Green procurement policy
In recognition of environmental conservation as one of the most important missions given to mankind andwe have strived to be an environmentally friendly company.
Although the control of our internal system is important, we also recognize that our suppliers havean important role in minimizing the environmental burden throughout our product life cycle.
Orbray (Thailand) Co., Ltd. commits to procure the "Environmentally Preferable Products" by,•Procure from suppliers who proactively promote the environmental protection.

•Procure materials and products that are environmental friendly and do not contain harmful substances.

OTH Green procurement guideline
1. Purpose
The environmental policy of Orbray (Thailand) Co., Ltd. (OTH) commits to providing
best-in-class products that are environmentally friendly and fully comply with international requirements
for controlled chemical substances and environmental-related systems.
This document is established for green procurement activities in order to effectively minimize
the use of environmental-related hazardous substances in materials/supplies based on the OTH
environmental policy in terms of sustainable development.
This is also a guideline for procurement activities that provides criteria for purchasing components
with the intention of selecting only those products that have low environmental impact and doing businesswith only those suppliers that have implemented environmental preservation activities.

2. Scope of application
This guideline is applicable to the suppliers that OTH are dealing with, who provide products
e.g., parts, supplies, chemical products and packing materials to OTH.

3. Terms and definitions-RoHS: Restriction of the use of certain hazardous substances in electrical and electronics equipment.
(EU) Directive 2002/95/EC, Directive 2011/65/EU and Directive 2015/863
REACH: Registration, Evaluation, Authorisation and Restriction of Chemicals(Regulation (EC) No 1272/2008)

4. OTH Environmental preservation activities
4.1 Environmental principle
OTH applies unique, clean technology to prevent pollution and protect the global environment.
The activities are intended to enhance the overall performance of environment preservation andcontribute to human health.
4.2 Environmental activities
OTH has established an environmental objective and target consistent with its environmental
policy, including the commitment to prevent pollution and strive for continual improvement.
Our activities are performed in a manner that respects nature, and we strive to protect and improve
the global environment. The environmental objective and target is subjected to periodic review atwhich time all technological options and business requirements are taken into account.
In order to improve the effectiveness of our environmental performance, OTH has implemented anenvironmental management system (EMS) and obtained ISO14001 certification in the year 2000.
OTH's environmental policy is also made available to the public.

5. Basic concept of green procurement
OTH intends to minimize the hazardous substance content in our products, which requires the kindcooperation of our green partners. The following is a list of activities to help us reach our green
procurement goal.
1) Procurement of components from suppliers who implement environmental preservation
activities
Basically, our suppliers are required to conduct activities that demonstrate their commitment toenvironmental preservation.
OTH will consider whether or not a supplier has obtained ISO14001 certification
by a certified body (CB), ensuring the effective implementation of an environmental management
system. Suppliers certified by a CB will be given high priority during the procurement process.
2) Procurement of components, services and packing materials with low environmental
impactFor all product components including packing materials used for the product or in a product process.
OTH intends to use only those components that have low environmental impact or those that are
specifically designed for the environment (ecodesign ).

6. OTH Supplier requirements
OTH expects suppliers to cooperate by providing the environmental documents to us.
1) RoHS report, RoHS certificate
A document assuring RoHS compliance of the product provided to OTH.
2) Safety Data Sheet (SDS), Material composition list
A document showing the composition of materials and chemical products3) Other documents depending on each product type
They are defined based on the requirement of each product type.
OTH is very proud to have such great support from all our suppliers.
Our green procurement activities contribute to environmental awareness and minimize the impact
on the environment. Your cooperation and support makes it possible for us to provide the global
market with environmentally friendly products of unsurpassed quality.
If the base raw material of a component or a process condition is changed, or if a chemical
substance used in a component is changed, the supplier is required to submit the"Change application from supplier" so OTH could consider whether it is necessary for the supplier
to resubmit the environmental documents again.
Thank you for your cooperation.
