Step 1: Establish strong company management systems

Compliance Statement with Requirement: We have fully complied with Step 1: Establish strong management systems.

1. Has the refiner adopted a company policy regardi ng due diligence for supply chains of g old ?

The Heraeus group has adopted a company-wide policy binding for all entities (including HPM & HMT) regarding due diligence for the supply chain of conflict minerals including Gold, Tin, Tungsten and Tantalum as well as other precious metals.

Comments and Demonstration of Compliance: In 2007 we started formalizing our supply chain policy for Precious Metals which is based on our Code of Conduct and policy of compliance and ethics. Already in 2010 we added an additional focus on conflict minerals (including, but not limited to Gold, Tin, Tantalum and Tungsten). During the reporting year, we further continued to formalize our supply chain policy for Precious Metals which is consistent with the model set out in the Annex II of the OECD due diligence guidance. This sets out our responsibility for conducting risk based due diligence, screening and monitoring of all transactions and governance structures in place. The latest supply chain policy can be found on our website in the downloads section: http://heraeus-precious-metals.com/en/home/heraeus-precious-metals.aspx http://heraeus-materials-technology.com/en/home/heraeus-materials-technology.aspx

2. Has the refiner set up an internal management st ructure to support supply chain due diligence?

Heraeus Materials Technology and Heraeus Precious Metals have set up an internal management structure to support supply chain due diligence

Comments and Demonstration of Compliance: An internal management system has been set up to define the governance, roles and responsibilities, internal audit, communication and senior management review as per the adopted policy. The compliance officers have been assigned to design, supervise and review the overall process, and have a direct line of reporting to the executive committee.

3. Has the refiner established a strong internal sy stem of due diligence, controls and transparency over gold supply chain, including traceability and identification of other supply chain actors?

Comments and Demonstration of Compliance: We have a robust ‘lot’ receipts process, and specific documents must be received and transactional details entered before we process any gold-bearing and other conflict materials. Each lot received is accurately registered in our transactional system and ensures complete traceability within our production streams. Specific controls regarding received materials are carried out before processing incoming material as outlined in our internal guidelines. Regular training of our employees ensures that our guidelines are followed through; any form of non-conformance is unacceptable and reported to the compliance officer and senior management. No such escalation was necessary during the reporting period.

4. Has the refiner strengthened company engagement with gold supplying counterparties, and where possible, assist gold supplying counterparties in b uilding due diligence capabilities?

Comments and Demonstration of Compliance: During the reporting period Heraeus has strengthened company engagement with gold supplying counterparts, as well as other suppliers of potentially conflict minerals. In 2012 we started the process to further modify our supplier agreements so that they make reference to the OECD guidelines and the latest version of “Code of Conduct for Precious Metal Suppliers of Heraeus” can be found on our website under in the downloads section: http://heraeus-precious-metals.com/en/home/heraeus-precious-metals.aspx. We reviewed the high risk countries and extended the list in 4Q2012 to include also all neighboring countries of the Democratic Republic of Congo. All new suppliers have to sign the latest version of our “Code of Conduct for Precious Metal Suppliers of Heraeus” before we are entering into a new business relationship. Based on our risk assessment, we are now renewing our due diligence checks for all our suppliers every one, three or five years.

5. Has the refiner established a company -wide communication mechanism to promote broad based employee participation and risk identification to m anagement?

Comments and Demonstration of Compliance: Heraeus has developed a mechanism allowing employees to voice concerns over the gold supply chain or other identified risks regarding conflict minerals or other compliance issues. A functional mailbox has been established which is reviewed by the compliance officer of the Heraeus group.

Step 2: Identify and assess risks in the supply cha in

Compliance Statement with Requirement: We have fully complied with Step 2: Identify and assess risks in the supply chain.

1. Does the refiner ha s a process to identify risks in the supply chain?

Heraeus has processes in place to identify the risks in the supply chain

Comments and Demonstration of Compliance: We identify and assess risks in the supply chain. For every supplier we have established a client database and allocated a risk profile according to our risk profile criteria. This process is now a formal requirement before entering any business relationship with any Precious Metals counterparty, including but not limited to Gold. Our due diligence process is carried out on a risk-based approach and follows our requirements as outlined in our “Code of Conduct for Precious Metal Suppliers of Heraeus”.

2. Does the refiner assess risks in light of the st andards of their due diligence system?

Heraeus assesses the risk in light of the standards of our due diligence system

Comments and Demonstration of Compliance: Supply chain due diligence comprising all measures required by the LBMA is performed before entering into a business relationship with any gold or other conflict minerals supplying counterpart. We performed enhanced due diligence for higher risk categories, which includes all gold-bearing mining material and where gold potentially originates from or transits via conflict affected areas and areas with human rights abuse, child labor or other high risk factors. In addition, we conduct appropriate scrutiny and monitoring of transactions undertaken through the course of the relationship following a risk based approach. If our due diligence assessment leaves doubts, we refuse to enter into a new business based on our risk criteria.

3. Does the refiner report risk assessment to the d esignated manager?

Comments and Demonstration of Compliance: The Compliance officers and their teams assess the potential risks in-line with Heraeus internal guidelines as well as the OECD due diligence guidance as set out in the Annex II. If risks are identified with new or existing business partners he will deny acceptance of new business partner or cancel business with existing partners. Only if the business disagrees with the assessment of the compliance officer, the issue will be escalated to the CEO or CFO for final decision; no such escalation was necessary during the reporting period. Senior management retains the ultimate control and responsibility for the Precious Metal supply chain, including, but not limited to Gold.

Step 3: Design and implement a management system to respond to identified risks

Compliance Statement with Requirement: We have fully complied with Step 3: Design and implement a management system to respond to identified risks.

1. Has the refiner devised a strategy for risk managem ent of an identified risk by either (i) mitigation of the risk while continuing to trade; (ii) mitigat ion of the risk while suspending trade or (iii) disengagement from the risk

Heraeus has devised a strategy for risk management of an identified risk by either (i) mitigation of the risk while continuing to trade; (ii) mitigation of the risk while suspending trade or (iii) disengagement from the risk

Comments and Demonstration of Compliance: Heraeus has set-up an automated and ongoing screening of all business partners for identifying risks. In addition and based on the risk assessment a regular assessment of all business partners and transactions is established. In addition any ad-hoc identified risk brought up by any stakeholder will be carefully assessed by the Compliance officer and his team and necessary actions/measures decided.

2. Where a management strategy of risk mitigation i s undertaken, it should include measureable steps to be taken and achieved, monitoring of perfo rmance, periodic reassessment of risk, and regular reporting to designated senior management.

Comments and Demonstration of Compliance: Corresponding procedures are in place and are –when necessary – applied accordingly

Step 4: Arrange for an independent third -party audit of the supply chain due diligence

Compliance Statement with Requirement: We have fully complied with Step 4: Arrange for an independent third-party audit of the supply chain due diligence.

Independent Reasonable Assurance Report

We have been engaged by Heraeus Precious Metals GmbH & Co. KG, Hanau, and Heraeus Materials Technology GmbH & Co. KG, Hanau, (the "Refiners") to perform a reasonable assurance engagement on the joint Refiners’ Compliance Report prepared by Heraeus Precious Metals GmbH & Co. KG for the business units "Heraeus Precious Metals" (HPM) and "Heraeus Material Technologies" (HMT) as defined in Table 5 of the Refiners’ Compliance Report for the year ended 31 December 2012 (the "Refiners’ Compliance Report").

The independent assurance scope consists of the Refiners’ Compliance Report.

Responsibilities

The management of the Refiners is responsible for the preparation and presentation of the Refiners’ Compliance Report in accordance with the LBMA Responsible Gold Guidance (version 5) as of January 18, 2013, as well as the Supplement on Tin, Tantalum and Tungsten of the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas as of November 2012 (the "Guidance"). This responsibility includes establishing appropriate risk management and internal controls from which the reported information is derived. The criteria identified by the management as relevant for demonstrating compliance with the Guidance are the activities described within the Refiners’ Compliance Report.

Our responsibility is to carry out a reasonable assurance engagement in order to express a conclusion based on the work performed.

We conducted our reasonable assurance engagement in accordance with International Standard on Assurance Engagements (ISAE) 3000 Assurance Engagements other than Audits or Reviews of Historical Financial Information issued by the International Auditing and Assurance Standards Board and the supplementary guidance set out in the LBMA Responsible Gold Programme - Third Party Audit Guidance (version 2) as of January 18, 2013 (the "Audit Guidance"). This Audit Guidance requires that we comply with ethical requirements and plan and perform the assurance engagement, under consideration of materiality, to express our conclusion with reasonable assurance.

The procedures selected depend on the practitioner’s judgment. Knowledge of the business activities and the economic and legal environment of the Refiners are taken into account in the determination of evidence-gathering procedures. Internal controls relevant to the preparation of the Refiners’ Compliance Report and the evidence supporting the disclosures in the Refiners’ Compliance Report are examined primarily

on a test basis within the framework of our work. Within the scope of our work we performed amongst others the following procedures:

Interviews with the compliance officers in charge of the preparation of the Refiners’ Compliance Report.

Interviews with management and employees of departments in charge of Recycling, Purchasing and Trading.

Inspection of relevant corporate guidelines and documents describing the Management Systems, Due Diligence and Risk Management approach towards a responsible supply chain.

Review of documentation of requirements on the group-wide processes for collecting, analyzing, and aggregating data on the supply chain of gold, tin, tantalum and tungsten.

Site visits in Refiners’ locations in Hanau, Hong Kong, New York, and Newark as part of our sample assessments of relevant systems, processes and controls.

Evaluation of the consistency of the statements provided in the Refiners’ Compliance Report with the findings obtained during our engagement.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our conclusion.

This independent assurance report has been prepared for the Refiners for the purpose of assisting the management in determining whether the Refiners have complied with the Guidance and for no other purpose. Our independent assurance report is made solely to the Refiners in accordance with the terms of our engagement. We do not accept or assume responsibility to anyone other than the Refiners for our work, or for the conclusions we have reached in the independent assurance report.

Inherent limitations

Non-financial information, such as that included in the Refiners’ Compliance Report, is subject to more inherent limitations than financial information, given the more qualitative characteristics of the subject matter and the methods used for determining such information. The methods used by Refiners to comply with the Guidance may differ. It is important to read the Refiners’ conflict minerals supply chain policy available in the download section on HPM and HMT website:
