Declaration of compliance in relation to conflict minerals

Re: Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act

Dear customer,

The Dodd-Frank Wall Street Reform and Consumer Protection Act required that the United States Securities Exchange Commission issue new obligations on companies filing reports with the Commission in relation to the reporting and declaration of ‘conflict minerals’ originating from the Democratic Republic of the Congo (DRC) or an adjoining country.

The term ‘conflict minerals’ means columbite-tantalite (also known as coltan; tantalum is extracted from this mineral), cassiterite (an ore yielding tin), gold, wolframite (the ore from which tungsten is extracted), or their derivatives; or any other mineral or its derivatives determined by the Secretary of State to be financing conflict in the DRC or an adjoining country. The new reporting obligations apply to these four minerals and their tantalum, tin and tungsten derivatives.

 An ‘adjoining country’ is any country sharing a border with the DRC, which currently encompasses Angola, Burundi, the Central African Republic, the Republic of the Congo, Rwanda, South Sudan, Tanzania, Uganda and Zambia.

PHT hereby certifies that its products:

- Do not contain any conflict minerals.

- Do not require the use of conflict minerals in their manufacture.

Yours faithfully,
