ADB Group takes very seriously the worldwide concerns that minerals, mined in the Democratic Republic of Congo (“DRC”) and in the adjoining Countries of the same region in Africa (defined as “Conflict Regions”), where revenues may be directly or indirectly financing armed groups engaged in civil war, result in serious human rights and environmental abuses.

As a manufacturer of products that may contain gold, tantalum, tin and tungsten (3TG Minerals), ADB Group is committed to operate in a socially and environmentally responsible way, fully supporting its Customers as part of the Supply Chain as per the “Dodd- Frank Financial Reform Bill section 1502(b)”, and refraining from purchasing from any known conflict sources. ADB Group expects its suppliers to also adhere to these principles.

ADB Group is implementing a due diligence program to identify and trace the 3TG minerals in its supply chain, based on the procedures and tools provided by the Electronic Industry Citizenship Coalition (EICC)/Global e-Sustainability Initiative (GeSI) and the Organization for Economic Co-operation and Development (OECD).

Accordingly, ADB Group shall manage its own supply chain according to the following principles:

• • Expect that its suppliers use materials from socially responsible suppliers, using sources from other regions or from certified non-conflict sources located in the DRC and surroundings areas (conflict-free status);

• • Expect that its suppliers provide in writing all the information needed to demonstrate their compliance with this policy and adopting the EICC/GeSI Mineral Reporting Template;

• • Suppliers must pass these requirements on to their supply chain, if they don’t source directly from smelters, and determine the source of specified materials;

• • Suppliers which are non-compliant with these requirements shall implement appropriate actions to transition in a socially and environmentally responsible supply chain.
