The mining and trade of coltan (from which tantalum ore is extracted), wolframite (from which tungsten is extracted), tin (from which tin is extracted from metal ores), gold, cobalt, mica and their respective derivatives from the Democratic Republic of the Congo ("DRC") or neighboring countries ("DRC region") have financed further conflicts among armed groups, leading to serious violations of human rights and environmental degradation. Section 1502 of the Dodd Frank Wall Street Reform and Consumer Protection Act (the Conflict Minerals Act) requires reporting to the U.S. Securities and Exchange Commission that companies and their chain of custody are required to be questioned about the source of conflict minerals and report their 'DRC conflict free' status.

        WUS fully supports this legislation with the aim of minimizing violence and environmental damage in the Democratic Republic of Congo. We will comply with all applicable obligations under the Conflict Minerals Law and conduct due diligence in accordance with OECD guidelines. WUS expects all suppliers to comply with the Conflict Minerals Act and provide all necessary declarations using the RMI Conflict Minerals Reporting Template. These measures will work together with the industry to propose a conflict free smelter investigation procedure to ensure that tantalum, tungsten, tin, gold, cobalt and mica are used reasonably in our products. We will only purchase from smelters/refinery that have been verified by an independent third party. The products provided will not directly or indirectly benefit armed groups that seriously violate human rights. WUS will evaluate if the supplier's future business does not comply with this policy.

        WUS is committed to ethical standards and compliance with applicable laws and regulations in its business sector.
