RDH recognize that risks of significant adverse impacts which may be associated with extracting,trading,handling an dexporting minerals from conflict-affected and high-risk areas, and recognizing that we have the responsibility to respect human rights and not contribute to conflict, we commit to adopt, widely disseminate, and incorporate in contracts and/or agreements with suppliers the following policy on responsible sourcing of minerals from conflict-affected and high-risk areas, as representing a common reference for conflict-sensitive sourcing practices and suppliers’ risk awareness from the point of extraction until end user. We commit to refraining from any action which contributes to the financing of conflict, and we commit to comply with relevant United Nations sanctions resolutions or, where applicable, domestic laws implementing such resolutions. Additionally, for suppliers of metals and minerals, we commit to conduct due diligence in accordance with the 5-Step due diligence framework defined in Annex I of the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas 3rd Edition
(the OECD Guidance).

We at RDH are committed in ensuring the following:
Regarding serious abuses associated with the extraction, transport or trade of
minerals:
1. While sourcing from, or operating in, conflict-affected and high-risk areas, we will
neither tolerate nor by any means profit from, contribute to, assist with or facilitate the
commission by any party of:
        1. any forms of torture, cruel, inhuman and degrading treatment;
         2. any forms of forced or compulsory labour, which means work or service
            which is exacted from any person under the menace of penalty and for
            which said person has not offered himself voluntarily;
         3. the worst forms of child labour;
         4. other gross human rights violations and abuses such as widespread
           sexual violence;
         5. war crimes or other serious violations of international humanitarian law,
           crimes against humanity or genocide.

Regarding risk management of serious abuses:

2. We will immediately suspend or discontinue engagement with upstream suppliers
where we identify a reasonable risk that they are sourcing from, or linked to, any
party committing serious abuses as defined in paragraph 1.

Regarding direct or indirect support to non-state armed groups:

3. We will not tolerate any direct or indirect support to non-state armed groups
through the extraction, transport, trade, handling or export of minerals. “Direct or
indirect support” to non-state armed groups through the extraction, transport, trade, handling or export of minerals includes, but is not limited to, procuring minerals from, making payments to or otherwise providing logistical assistance or equipment to, nonstate armed groups or their affiliates who:

         1. illegally control mine sites or otherwise control transportation routes, points
            where minerals are traded and upstream actors in the supply chain;5 and/or
         2. illegally tax or extort6 money or minerals at points of access to mine sites,
            along transportation routes or at points where minerals are traded; and/or
         3. illegally tax or extort intermediaries, export companies or international
           traders.

Regarding risk management of direct or indirect support to non-state armed
groups:

4. We will immediately suspend or discontinue engagement with upstream suppliers
where we identify a reasonable risk that they are sourcing from, or linked to, any
party providing direct or indirect support to non-state armed groups as defined in
paragraph 3.

Regarding public or private security forces:

5. We agree to eliminate, in accordance with paragraph 10, direct or indirect support to public or private security forces who illegally control mine sites, transportation routes and upstream actors in the supply chain; illegally tax or extort money or minerals at point of access to mine sites, along transportation routes or at points where minerals are traded; or illegally tax or extort intermediaries, export companies or international traders.

6. We recognise that the role of public or private security forces at the mine sites
and/or surrounding areas and/or along transportation routes should be solely to
maintain the rule of law, including safeguarding human rights, providing security to mine workers, equipment and facilities, and protecting the mine site or transportation routes from interference with legitimate extraction and trade.

7. Where we or any company in our supply chain contract public or private
security forces, we commit to or we will require that such security forces will
be engaged in accordance with the Voluntary Principles on Security and
Human Rights. In particular, we will support or take steps, to adopt screening
policies to ensure that individuals or units of security forces that are known
to have been responsible for gross human rights abuses will not be hired.

8. We will support efforts, or take steps, to engage with central or local authorities, international organisations and civil society organisations to contribute to workable solutions on how transparency, proportionality and accountability in payments made to public security forces for the provision of security could be improved.

9. We will support efforts, or take steps, to engage with local authorities,
international organisations and civil society organisations to avoid or minimise
the exposure of vulnerable groups, in particular, artisanal miners where
minerals in the supply chain are extracted through artisanal or small-scale mining, to adverse impacts associated with the presence of security forces,public or private, on mine sites.

Regarding risk management of public or private security forces:

10. In accordance with the specific position of the company in the supply chain, we
will immediately devise, adopt and implement a risk management plan with upstream suppliers and other stakeholders to prevent or mitigate the risk of direct or indirect support to public or private security forces, as identified in paragraph 5, where we identify that such a reasonable risk exists. In such cases, we will suspend or discontinue engagement with upstream suppliers after failed attempts at mitigation within six months from the adoption of the risk management plan.8 Where we identify a reasonable risk of activities inconsistent with paragraphs 8 and 9, we will respond in the same vein.

Regarding bribery and fraudulent misrepresentation of the origin of minerals:

11. We will not offer, promise, give or demand any bribes, and will resist the
solicitation of bribes to conceal or disguise the origin of minerals, to misrepresent
taxes, fees and royalties paid to governments for the purposes of mineral extraction,
trade, handling, transport and export.

Regarding money laundering:

12. We will support efforts, or take steps, to contribute to the effective elimination of money laundering where we identify a reasonable risk of money-laundering resulting from, or connected to, the extraction, trade, handling, transport or export of minerals derived from the illegal taxation or extortion of minerals at points of access to mine sites, along transportation routes or at points where minerals are traded by upstream suppliers.

Regarding the payment of taxes, fees and royalties due to governments:

13. We will ensure that all taxes, fees, and royalties related to mineral extraction,
trade and export from conflict-affected and high-risk areas are paid to governments
and, in accordance with the company’s position in the supply chain, we commit to
disclose such payments in accordance with the principles set forth under the
Extractive Industry Transparency Initiative (EITI).

Regarding risk management of bribery and fraudulent misrepresentation of the origin of minerals, money-laundering and payment of taxes, fees and royalties to
governments:

14. In accordance with the specific position of the company in the supply chain, we
commit to engage with suppliers, central or local governmental authorities,
international organisations, civil society and affected third parties, as appropriate, to
improve and track performance with a view to preventing or mitigating risks of
adverse impacts through measureable steps taken in reasonable timescales. We will
suspend or discontinue engagement with upstream suppliers after failed attempts at
mitigation.

Additionally, for suppliers of metals and minerals, we commit to conduct due diligence
in accordance with the 5-Step due diligence framework defined in Annex I of the OECD
Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-
Affected and High-Risk Areas 3rd Edition (‘the OECD Guidance’).

I, CHEN, KUEI-YUAN, general manager of RDH, personally affirm this commitment
by leading the effort in supporting and promoting Responsible Minerals Assurance
Program (RMAP) schemes. We are fully committed to a strategy of meeting the
requirement of RBA,OECD and Governments of the affected countries and subscribe
to a longer-term objective of improving the tin industry of the region.
