2 THE BHP BILLITON WAY

CEO Message

At BHP Billiton, Our Purpose is to create long-term shareholder value through the discovery, acquisition, development and marketing of natural resources. Our consistent strategy to own and operate large, long-life, low-cost, expandable, upstream assets, diversified by commodity, geography and market has resulted in us holding a unique position in the resources industry and delivering value to our shareholders.

To secure our future, we must continue to deliver a stable and dependable cash flow that enables us to invest in growth. Our ability to do this in the past has helped make us one of the leading natural resources companies in the world. However, we are only successful today because of the actions of the people who came before us over a history spanning more than 150 years.

We can never take our performance for granted. Each day, we must safely operate all of our assets at capacity and continue to identify those resources we will leave to the next generation of BHP Billiton leaders. Without exception we must do our work in a way that is consistent with Our Charter values and Code of Business Conduct. It is only when we work in this way that we can continue to work on behalf of our shareholders and communities that we are privileged to serve.

The BHP Billiton Way has been designed to give you a snap shot of what we do and how we do it. It contains Our Charter and the role it plays in communicating, not only what we do, but the way in which we are all expected to work. Its values are central to our way of working and have fundamentally remained unchanged since the Charter was first introduced in 1999. Our values form the basis of the Code of Business Conduct.

The BHP Billiton Way also outlines how we have structured our Company to deliver our strategy. It includes our Operating Model, which describes how accountabilities are divided across the Company. It helps each of us understand our role in delivering the strategy and the measures against which we will be held to account.

We are a large and globally diverse business. We also have a workforce diversified by gender, nationality, ethnicity, skill, thought and style, and we take pride in the strength that comes from our diversity.

The BHP Billiton Way is your tool to better understand how our Company operates.

Marius KloppersChief Executive Officer

At BHP Billiton, we aspire to be the world’s best natural resources company.

THE BHP BILLITON WAY 3

Governance and Management at BHP Billiton

We are committed to the highest level of governance and strive to foster a culture that values and rewards exemplary ethical standards, personal and corporate integrity and respect for others. The Board governs the Group consistent with Our Charter values, long stated business strategy and commitment to a transparent and high-quality governance system.

Our approach to governance is predicated on the belief that there is a link between high-quality governance and the creation of long-term shareholder value. It is our view that governance is not just a matter for the Board; a culture of good governance must be fostered throughout the organisation.

The Board has delegated to the Chief Executive Officer all authority to manage the business of the Group to achieve Our Purpose. The CEO has, in turn, established the Group Management Committee (GMC), a management structure to enable him to effectively execute his authority in a way that is consistent with the expectations of the Board.

The GMC provides advice to the Chief Executive Officer on matters that are strategic and long-term in nature, or have the potential to significantly impact the Group’s performance and reputation.

An important role for the GMC is to determine the way the Group operates. This involves setting the organisation structure and Operating Model; defining the accountabilities and scope of Customer Sector Groups (CSGs), the Group Functions, Minerals Exploration and Marketing. The Group Functions operate as agents of the GMC in executing their mandates that are designed to ensure that we meet our governance requirements and that our business is run in the most effective way possible. A key part of the GMC’s role in this regard is to approve all Group Level Documents (GLDs). These documents contain the minimum mandatory performance requirements for the Group. In addition to accountabilities, they also contain the requisite approvals for decisions.

Strategic risks and opportunities arising from changes in our business are regularly reviewed by the GMC and discussed by the Board. The Board has established a number of committees to assist it in exercising its authority and to monitor the performance of the business. This ensures that a robust governance and management culture is fostered throughout the organisation.

Sustainability our priority is to ensure that all our people return home safe and well at the end of every working day. effective health and safety performance is critical to us. We all have a role to play in ensuring we care for our colleagues and take the appropriate steps to prevent workplace related injuries and illness.

operating sustainably underpins everything we do. We work to improve energy efficiency, reduce pollution, enhance biodiversity and improve the quality of life of people in our surrounding communities.

Simplicity We focus our energy on the activities that create the most value for the organisation. We strive to reduce complexity wherever we see it by simplifying processes and stopping low value adding activities.

Accountability our success is driven by the decisions we take and how well we execute them. This requires each of us to take responsibility for what we commit to and ensures the best outcomes are delivered to our stakeholders.

Our Charter is the single most important means by which we communicate who we are, what we do and what we stand for as an organisation. it is through Our Charter we articulate our Purpose, our strategy, the values we uphold and how we measure success. Our Charter is the foundation for our decision-making, actions and behaviours.

Our Charter makes it clear that as we strive for success we must remain forthright in the things we value: Sustainability, integrity, Respect, Performance, Simplicity and Accountability.

Operating Model

our operating Model has been designed to deliver a simple and scalable organisation, providing a competitive advantage through defining how we work, how we are organised and how we measure performance. By having a common set of organisation design principles, systems and processes, and a defined set of performance requirements, we can achieve our Purpose and provide a planned, controlled and safe work environment for our people where all risks are managed.

our Organisation Design GLD (GlD.001) stipulates how we structure our organisation and defines the roles and accountabilities of our people, empowering them to apply their functional expertise to solve complex problems in a world-class manner. We value our people and they are the foundation of our success. We are committed to providing career opportunities and engaging our people to reach their full potential.

We have a common set of functions at the CSG, Asset and operation level, with clear lines of accountability that foster functional excellence. Functional services are aggregated at the Assets so that operations can remain focused on safety, production and cost. our CSGs are focused on strategy, growing the value of their businesses and

governing their Assets and major projects. our Minerals exploration team find our future resources and our Marketing team manage our customer relationships and sell our products.

each one of our 16 Group Functions has a clear mandate approved by the GMC. our GlDs contain the mandatory requirements imposed on all parts of the business and set out the authorities framework. Compliance with these GlDs ensures BhP Billiton’s reputation is effectively managed; we meet our minimum standards and we are focusing on the things that matter most.

Clear accountabilities and transparent data mean we make informed decisions every time and provide a framework for our people so they know they are contributing in a positive and measurable way. our operating Model ensures the health and safety of our people and the delivery to plan of our products at the lowest possible cost. our shareholders, customers, suppliers and communities respect the way we conduct business, our integrity and the quality of our people and processes.

Group Management Committee

The GMC provides leadership to the Group by determining our priorities and the way we operate as an organisation. it has organised the Group into CSGs, Minerals exploration, Marketing and Group Functions, who work together in pursuit of our Purpose. The role of each organisation unit and their relationship to each other is set out in GlD.001.

Minerals Exploration Minerals exploration is responsible for identifying and acquiring greenfield exploration opportunities that have the potential to be giant mineral resources; undertaking all minerals greenfield exploration activities including target definition, target testing and post discovery delineation; endorsing all resource and geoscience inputs into greenfield identification phase study activities conducted by CSGs, including acquisitions.

Customer Sector Groups

CSGs are organised on a standardised basis comprising distinct organisational units: CSG, Asset and operation. each level comprises a core of common functional services that operate according to defined roles.CSG-levelThe CSG sets strategy, grows the value of its business and governs its Assets and projects.Asset-levelAn Asset is comprised of one or more operations in a single country and is operated by BhP Billiton. it is the level at which we aggregate functional services. each Asset is responsible for the provision of functional services and integrated planning and development to its operations. This aggregation of work removes from the operations all service activities with the exception of those minimum execution-level activities necessary for managing safety, production and cost. By doing this, we establish deep functional capability at the Asset-level and improve our ability to plan.Project HubsProject hubs are an operating centre for managing our pipeline of major capital projects. Project hubs are organised around major core products and positioned in key global locations to improve the performance, standardisation, repeatability and effectiveness of our project delivery. This enables the consistent application of best project practices and facilitates driving continuous improvement in our project performance.Operation-levelAn operation is a substantially distinct production entity operated by BhP Billiton, such as a mine, port or group of processing or production facilities, with defined boundaries and agreed points of handover for services and/or product. operations execute planned work and focus on safety, production and cost.

Marketing Marketing manages the Group revenue line and is responsible for selling the Group’s products and for the purchase of all major raw materials; owning the supply chain from Assets to markets and raw materials from suppliers to Assets; achieving market clearing prices for the Group’s products and zero directional price risk; and developing a single Company view of the markets.

Group Functions Group Functions operate under a defined set of mandates and accountabilities authorised by the GMC that specifically relate to the governance of BhP Billiton, the Ceo limits established by the Board, and activities necessary to improve the overall effectiveness of the Group.

Group level Documents

our GlDs give effect to the mandatory requirements arising from our operating Model as approved by the GMC. They describe the mandatory minimum performance requirements and accountabilities for definitive business obligations, processes, functions and activities across BhP Billiton.

Processes our defined global business processes, including 1SAP, provide a standardised way of working across the organisation. our common processes generate reliable data, improve operating discipline and ensure we do the basics well.
