Duro-Sense Conflict Materials Statement

In response to violence and human rights violations in the mining of certain minerals from the "CONFLICT REGION", which is located in the eastern portion Of the Democratic Republic of the Congo (DRC) and the surrounding countries, the United States Securities and Exchange Commission (SEC) has adopted rules to implement reporting and disclosure requirements related to "CONFLICT MINERALS", as directed by the wall street Reform and consumer Protection Act (also known as the Dodd-Frank Act) of 2010. The rules require manufacturers Who file certain reports with the SEC to disclose whether the products they manufacture, Or contract to manufacture, contain "CONFLICT MINERALS" that are" necessary to the functionality or production" of those products.

The definition of "CONFLICT MINERALS" refers to gold, tin, tantalum and tungsten, the derivatives of cassiterite, columblte-tantalite, and wolframite, regardless of where they are sourced, processed or sold. The U.S. Secretary of State may designate other minerals in the future. We support the humanitarian goal of ending violent conflict in the DRC and the surrounding countries.

We are committed to the responsible sourcing Of "CONFLICT MINERALS" throughout our supply chain and to continue to comply with the underlying SEC rules and regulations surrounding "CONFLICT MINERALS".
