Rio Tinto and BHP Billiton announce Western Australian Iron Ore Production Joint
Venture                                                                         
Rio  Tinto and BHP Billiton today signed a non-binding agreement to establish  a
production  joint  venture  covering the entirety  of  both  companies`  Western
Australian  iron ore assets.  The joint venture will encompass all  current  and
future  Western  Australian iron ore assets and liabilities and  will  be  owned
50:50 by BHP Billiton and Rio Tinto.                                            
The  joint  venture is expected to unlock significant value from the  companies`
overlapping,  world-class resources.  Both companies  believe  the  net  present
value of these unique production and development synergies will be in excess  of
US$10 billion (100 per cent basis).  These substantial synergies are anticipated
to come from:                                                                   
* Combining adjacent mines into single operations;                              
*Reducing  costs  through shorter rail hauls and more efficient  allocations  of
port capacity;                                                                  
*Blending  opportunities  which  will  maximise  product  recovery  and  provide
further operating efficiencies;                                                 
*Optimising   future   growth   opportunities   through   the   development   of
consolidated, larger and more capital efficient expansion projects; and         
*Combining  the management, procurement and general overhead activities  into  a
single entity.                                                                  
The  joint venture will operate as a cost centre and deliver iron ore, in  equal
volumes, to ships designated by BHP Billiton and Rio Tinto to sell independently
through their own marketing groups. In order to equalise the contribution  value
of  the two companies, BHP Billiton will pay Rio Tinto US$5.8 billion for equity
type interests at financial close to take its interest in the joint venture from
45 per cent to 50 per cent.                                                     
Senior  management of the entity will be determined jointly on the basis of  the
`best  person for the job` with broadly equal participation from Rio  Tinto  and
BHP Billiton.  The initial Chairman of the non-executive owners` council will be
Sam Walsh, currently Rio Tinto Chief Executive Iron Ore, and the initial CEO  of
the production joint venture will be BHP Billiton Iron Ore President, Ian Ashby.
Future CEOs will be appointed by mutual consent.                                
Commenting  on the joint venture, Rio Tinto Chairman Jan du Plessis  said,  "The
joint  venture will establish an unrivalled iron ore business with  world  class
assets and infrastructure. We believe it represents great value for shareholders
and  will  create  a  business combination able to serve  growing  international
markets with unparalleled efficiency."                                          
BHP  Billiton  Chairman, Don Argus, said, "I am delighted that we  are  able  to
announce  a  transaction  that  can deliver significant  real  and  quantifiable
synergies  to  our  shareholders. The combination of these two asset  portfolios
will unlock the scale benefits inherent in this world class resource basin."    
BHP Billiton CEO Marius Kloppers said, "The synergies in this combination are so
substantial  that both companies have been investigating ways to  combine  these
operations for more than a decade.  I am delighted that we have found a solution
that  works  for both companies.  This joint venture brings together world-class
iron ore resources, infrastructure and people, unlocks large synergies and is an
outstanding outcome for all stakeholders."                                      
Tom  Albanese, Chief Executive of Rio Tinto, said, "We have long recognised  the
natural fit of our two iron ore businesses and the industrial logic for bringing
them together in order to unlock substantial synergies. We are very pleased that
we have been able to realise this vision which offers value to both companies." 
Technology  and  research  and development activity will  also  be  shared.  The
agreement  excludes HIsmelt, any secondary processing facilities, and operations
and future business development outside Western Australia.                      
Rio  Tinto  and  BHP  Billiton will now move to signing definitive  and  binding
transaction documentation as soon as practicable based on the agreed  principles
set  out  in  the attached agreement that has been signed today.  Pre-conditions
for  formation of the joint venture include receipt of regulatory  and  relevant
governmental clearances and approval from the shareholders of both Rio Tinto and
BHP Billiton.                                                                   
Rio  Tinto  and BHP Billiton have also agreed to certain exclusivity  and  other
provisions  that  commit both parties to negotiate binding agreements  governing
the  formation  of the joint venture, including a mutual break fee  of  US$275.5
million  payable  in  the  event  that either  party  does  not  fulfil  certain
commitments to complete those documents.  The break fee would also be payable in
the event that either party:                                                    
 a) announces that it does not intend to proceed with the transaction; or       
                                                                                
 b) fails  to  recommend the transaction to its shareholders or take the  steps 
necessary to obtain the approval of its shareholders; or                    
                                                                                
 c)    breaches the agreed exclusivity provisions.                              
                                                                                
The  attached  agreement will terminate if binding agreements are  not  executed
within  six months of the date of this announcement or the conditions  precedent
are  not  satisfied  by  31 December 2010.  Formation of the  joint  venture  is
expected to be completed around mid-2010.

Forward Looking Statements                                                      
This announcement includes "forward-looking statements" within the meaning of   
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the   
Securities Exchange Act of 1934, as amended. All statements other than          
statements of historical facts included in this announcement, including, without
limitation, those regarding Rio Tinto and BHP Billiton`s respective financial   
positions, business strategies, plans and objectives of management for future   
operations (including development plans and objectives relating to the products,
production forecasts and reserve and resource positions of each of Rio Tinto and
BHP Billiton) and synergies arising out of the proposed joint venture are       
forward-looking statements. Such forward-looking statements involve known and   
unknown risks, uncertainties and other factors which may cause the actual       
results, performance or achievements of Rio Tinto or BHP Billiton, or industry  
results, to be materially different from any future results, performance or     
achievements expressed or implied by such forward-looking statements.           
Such forward-looking statements are based on numerous assumptions regarding Rio 
Tinto and BHP Billiton`s respective present and future business strategies and  
the environment in which Rio Tinto and BHP Billiton, respectively, will operate 
in the future. The important factors that could cause Rio Tinto and BHP         
Billiton`s actual results, performance or achievements to differ materially from
those in the forward-looking statements include, among others, levels of actual 
production during any period, levels of demand and market prices, the ability to
produce and transport products profitably, the impact of foreign currency       
exchange rates on market prices and operating costs, operational problems,      
political uncertainty and economic conditions in relevant areas of the world,   
the actions of competitors, activities by governmental authorities such as      
changes in taxation or regulation and such other risk factors identified in the 
most recent Annual Report on Form 20-F filed with the United States Securities  
and Exchange Commission (the "SEC") or Form 6-Ks furnished to the SEC by each of
Rio Tinto and BHP Billiton. Forward-looking statements should, therefore, be    
construed in light of such risk factors and undue reliance should not be placed 
on forward-looking statements. These forward-looking statements speak only as of
the date of this announcement. Each of Rio Tinto and BHP Billiton expressly     
disclaim any obligation or undertaking (except as required by applicable law,   
the UK Listing Rules, the Disclosure and Transparency Rules of the Financial    
Services Authority and the Listing Rules of the Australian Securities Exchange) 
to release publicly any updates or revisions to any forward-looking statement   
contained herein to reflect any change in Rio Tinto and BHP Billiton`s          
respective expectations with regard thereto or any change in events, conditions 
or circumstances on which any such statement is based.                          

                                                                                
              Term Sheet - West Australian Iron Ore Production JV               
Iron Ore Production JV                                                          
1.Overview                                                                      
 1.1.    BHP Billiton and Rio Tinto (the "Owners") will combine their           
     economic interests in all current and future iron ore assets (exploration  
     interests, leases, mines, rail, ports and ancillaries) in Western          
Australia and all related employees and contractors, into a single 50:50   
     joint venture.  All assets will remain in their current legal structures   
     (confidential provision deleted). The JV will assume all related           
     liabilities other than tax liabilities and material undisclosed            
liabilities, with a minimum claim of US$300 million and a maximum claim    
     period of 10 years.  It is intended that the joint venture will continue   
     in perpetuity.                                                             
 1.2. The joint venture would not include:                                      
(a) HBI, HIsmelt or any other secondary processing (otherwise than by one or   
    more of washing, drying, crushing or screening) unless required to satisfy  
    obligations under a future State Agreement or obligations not yet           
    satisfied under a current State Agreement;                                  
(b)marketing, except to the extent contemplated in item 4.8; and               
 (c)business development outside Western Australia.                             
                                                                                
 1.3.    The Owners economic interests in the JV will be 50:50.  In             
equalising to 50:50, BHP Billiton will subscribe an amount of US$5.8       
     billion (for an additional 5% of the JV) for tracking notes in Hamersley   
     Holdings, or other entity or means to be agreed with the equalisation      
     amount inflated from 1 July 2009 until completion at a nominal rate of     
6.5% per annum.                                                            
                                                                                
 1.4.    Conditional on completion, the Owners will share equally all risks,    
     costs and benefits of the JV from 1 July 2009.  The equalisation payment   
will be accordingly adjusted should the JV close after 1 July 2009, to     
     reflect movements in net cash flow after tax of the respective economic    
     interests making up the JV (including profits from product sales) between  
     the two dates at a nominal rate of 6.5% per annum, as adjusted, on a       
monthly basis from 1 July 2009 to completion. The governance arrangements  
     will be as set out below.                                                  
                                                                                
 1.5.    Subject to the other provisions of this document, the JV will supply   
equal product volumes and specification to each Owner (measured on equity  
     tonnes), delivered at ship`s rail.  Each Owner will market their share as  
     they see fit (except as otherwise agreed under item 4.8).                  
                                                                                
1.6.    Owners are obliged to fund the JV in equal shares as follows:          
 (a)the JV will operate with a minimum cash balance and will be financed        
    entirely by the Owners, hence third party debt free (including project      
    finance, trade debt and working capital facilities);                        
(b)cash will be called from the Owners on a regular basis to fund the JV       
    (with cash calls based on budget and an adjustment to reflect actual usage  
    and expenditure), including to fund capex programs; and                     
 (c)an Owner may elect to fund its portion of an expansion or acquisition on a  
project finance basis.  An Owner`s JV interest can also be used to secure   
    corporate debt.  In each case, any security given to a financier would      
    rank junior to the other Owner`s secured rights and would be subject to an  
    intercreditor deed in the form of a pro forma deed to be agreed as part of  
the binding agreements.                                                     
 1.7.    (Confidential provision deleted.)                                      
2.Governance of JV                                                              
 2.1.    Subject to the comments below in relation to assignment, a "Non-       
executive" Owners` Council representing the two Owners will oversee the    
     JV.  Each Owner will have one vote.                                        
 2.2.    Each Owner may appoint up to 4 representatives to attend meetings of   
     the Owners Council.                                                        
2.3.    The Chairmanship of the Owners` Council will rotate annually between   
     the Owners.                                                                
 2.4. The Owners Council will have the power to:                                
 (a)  approve the following high level policies;

         b. business conduct                                                    
         c. HSE                                                                 
         d. communities; and                                                    
e. such other policies as the Owners mutually agree are necessary or   
         desirable.

         o.approve entry into new State Agreements or material amendments to    
           existing State Agreements;

           direct reports; and                                                  
                                                                                
q.approve the use of patented intellectual property owned or licensed  
           to the JV by the Owner that does not own the patented intellectual

2.5.    Subject to the functions and powers of the Owners Council, the         
     Manager (at the direction of the CEO) will have clear authority to manage  
     and carry out all JV activities and the Owners will not interfere with     
     the day-to-day management of those activities.  The CEO will be required   
to act in accordance with the governance arrangements.  The separate       
     references to the CEO are not intended to suggest otherwise.               
 2.6.    A quorum for the Owners Council requires a minimum of one              
     representative of each Owner.                                              
2.7.    All Owners` Council decisions must be approved by both Owners.         
     However, the parties recognise that there must be an unambiguous pathway   
     to ensure that deadlocks do not frustrate the development and operation    
     of the JV and the individual strategic objectives of the Owners.  All      
deadlocks will be dealt with in the manner described below and once        
     resolved, if relevant, that resolution will be reflected in the            
     appropriate plan or budget.                                                
    (a)In the event of a deadlock, the dispute would be escalated to the        
Owners` CEOs.  If the dispute is not resolved, it would be referred to  
        the Owners` Chairmen.                                                   
    (b)If the matter is still unresolved and if (but only if) it involves an    
        unresolved Owners Council decision relating to:                         

        f. communities/towns;                                                   
        g. indigenous groups;                                                   
         h. environment; or                                                     
i. OHS,                                                                
                                                                                
       the dispute would be referred to a suitable industry expert for          
       resolution.  If the expert reaches the view that the expenditure is not  
being proposed in whole or in part for a collateral purpose, or other    
       reasons which are not wholly connected with the JV, that proposal or     
       expenditure will proceed.                                                
                                                                                
(c)If the matter is unresolved and involves a proposal for the             
        satisfaction of a secondary processing obligation under a current or    
        future State Agreement or any other obligation to be imposed by a       
        Government (including any matter arising under a State Agreement or     
imposed by the State as a condition to any approval) or relates to the  
        preservation of tenure, the matter will be referred to a suitably       
        qualified industry expert for prompt resolution.                        
     (d)If there is a disagreement in relation to the appointment of the JV     
CEO, the current CEOs appointment continues.  If the CEO resigns and    
        there is a disagreement in relation to a replacement, the Chairman      
        will appoint a temporary CEO from existing reports to the CEO with      
        quarterly reviews and, if there is still disagreement, renewal of the   
temporary CEO for a further quarter.                                    
 2.8.    Notwithstanding item 2.4 the Manager is to submit an annual business   
     plan and budget based on Owner nominations.  If not approved, refer back   
     to Manager.  If still not approved when resubmitted, Manager`s business    
plan and budget prevails.                                                  
 2.9.    Equal access to information by both Owners and equal treatment.  In    
     addition, the Manager and the CEO are to have fiduciary obligations to     
     the Owners and are to act equitably and fairly and give due and equal      
consideration to each Owner.                                               
3.Management of JV                                                              
 3.1.    A new operating entity owned 50:50 to be formed and appointed day to   
     day operator, with a CEO who is also the executive head of the JV.  This   
entity is referred to in this document as the Manager.                     
 3.2.    The CEO will be appointed by agreement between the Owners.             
 3.3.    The CEOs appointment will expire every four years.  On expiry, item    
     3.2 will apply.  In the application of item 3.2 it is recognised that      
continuity is important.                                                   
 3.4.    CEO can hire or dismiss any employee, but appointment of any direct    
     report to CEO (Senior Executive Team) requires approval of both Owners.    
 3.5.    Senior Executive Team sourced initially approximately 50:50 from Rio   
Tinto and BHP Billiton on "best of breed" basis.  This 50:50 balance is    
     to be maintained for the first 3 years of the JV.                          
 3.6.    All employees to be JV employees remunerated on the basis of JV        
     objectives subject to:                                                     
(a)pre-existing entitlements of transferring employees will be preserved;  
     (b)the JV will assume these obligations; and                               
     (c)any redundancy costs will be borne by the JV.                           
                                                                                
3.7.    No secondees or other position rights for either Owner.                
 3.8.    The CEO will have the mandate to make the JV operationally             
     standalone as soon as practically possible, without any service            
     agreements with either owner except as otherwise agreed.                   
3.9.    The JV will initially source systems, standards and procedures from    
     the Owners, selected on a `best of breed basis`.                           
     The JV will put in place its own procurement arrangements but the Manager  
     will have the discretion to utilise the procurement arrangements of the    
Owners to the extent the JV is able to do so and arrangements are in the   
     best interests of the JV.  The JV arrangements will be, subject to         
     approval by the Owners` Council.  Subject to compliance with competition   
     laws, the procurement arrangements may include:                            

     (a)the JV having its own stand alone procurement arrangements;             
                                                                                
     (b)the JV utilising the procurement arrangements of the Owners in a        
manner that is fair between the Owners;                                 
                                                                                
     (c)the Owners utilising the JVs procurement arrangements, in a manner      
        that is fair between he Owners; or                                      

     (d)any combination of the above.                                           
 3.10.   The Owners will license on a nonexclusive royalty free basis to the    
     JV all intellectual property and technology used in the respective West    
Australian iron ore businesses and grant the JV the rights to make         
     enhancements.  Each Owner will continue to own and have the right to use   
     its intellectual property (including patented intellectual property) and   
     technology (including patented technology) in other parts of its           
respective businesses.  Each Owner will have the right to use, on a non-   
     exclusive royalty free basis, in its other businesses, the other Owners`   
     unpatented intellectual property and technology, including any             
     improvements made by the JV, to the extent it has been licensed to the     
JV.  The Owners will own equally as tenants in common any improvements     
     thereto made by the JV.  Each Owner of the technology or intellectual      
     property (whether patented or not) underlying the improvement shall have   
     the right to use that improvement in its respective businesses but shall   
not further license the improved technology or improved intellectual       
     property (whether patented or not) outside its respective businesses.      
 3.11.   The Manager will adopt the principle of an owner operator model for    
     the JV so that it utilises employees in preference to contractors in long  
term operating roles within the JV.  To the extent that current            
     operations involve contractors in long term operating roles, the Manager   
     will progressively shift those operations to the owner operator model.     
 3.12.   The CEO will cause the Manager to develop and submit to the Owners     
Council for approval a plan to realise synergies.  The plan will include   
     a detailed description of the synergies that can be realised by the JV,    
     including those which have been identified by the parties and an action    
     plan to realise those synergies.                                           
3.13.   The synergies currently identified by the parties include:             
     (a)  resource optimisation;                                                
                                                                                
     (b)a product strategy to optimise mine development across the combined JV  
portfolio;                                                              
                                                                                
     (c)capex savings from using closest rail infrastructure for each East      
        Pilbara development;                                                    

     (d)blending of both Owner`s products to maximise resource recovery;        
                                                                                
     (e)shared use of infrastructure (rail, port and power) - HI / Robe,        
Yandi, Newman and Goldsworthy;                                          
                                                                                
     (f)infrastructure expansion - lowest cost and most efficient               
        infrastructure expansion pathway;                                       

     (g)berthing optimisation - improved berth utilisation from joint           
        operation of the ports, blending of product and joint scheduling of     
        each Owner`s ships between the ports;                                   

     (h)Yandi combination - opex and capex savings from joint operation and     
        expansion of Yandi;                                                     
                                                                                
(i)operating and procurement efficiencies - transfer of best practice,     
        joint procurement, shared services and shared equipment across the      
        Pilbara; and                                                            
                                                                                
(j)product group overhead savings - reduced duplication of corporate       
        overheads in Perth.                                                     
   It is anticipated that further synergies will be identified as the JV        
   progresses.                                                                  
4.Product Supply and Price of Supply                                            
 4.1.    The Manager will present an annual budget designed to optimise the     
     capacity from existing operations (including presenting options for        
     improvements).  Having received tonnage nominations from the Owners, the   
Manager will deliver that tonnage efficiently and at the lowest possible   
     cost, subject to system integrity and safety.                              
 4.2.    The JV management is to have no knowledge of the Owners` marketing     
     strategies or terms.                                                       
4.3.    (Confidential provision deleted.)                                      
 4.4.    (Confidential provision deleted.)                                      
 4.5.    (Confidential provision deleted.)                                      
 4.6.    Except as required by item 5.2 or as adjusted for "sole risk"          
expansions, equal, volumes of each product will be supplied to each Owner  
     at ship`s rail (excluding any existing JV partner`s share of production).  
     If one Owner does not wish to receive all of its tonnage entitlement in a  
     given period, the other Owner may take up that unused entitlement.  The    
additional tonnes delivered will constitute an ore loan.  There may be     
     limits on the amount of tonnes that may be borrowed in a year, or in       
     aggregate at any point in time.  The ore loan can be called by repayment   
     in kind (volume and specification), but the amount repayable in any given  
year may be limited, and notice periods will apply.                        
 4.7.    Owners will each fund capital and operating costs of the JV on a       
     50:50 basis except as adjusted for sole risk expansions (6.6)              
 4.8.    The Owners will agree to co-market certain of their respective         
volumes.  When the Owners do so, the following principles will apply:      
     (a)the JV will establish a separate marketing company;                     
                                                                                
     (b)10% of production and not more than 15 percent (as approved by the      
Owners) will be sold jointly on the spot market or otherwise as agreed  
        by the Owners;                                                          
                                                                                
     (c)the joint marketing arrangement will be renewed automatically every 5   
years unless one Owner requests a review at the end of that period.     
        If any Owner is not satisfied with the outcome of that review, that     
        Owner may give notice requesting termination.  If both Owners mutually  
        agree, the arrangement will terminate.  If the Owners do not agree      
within 6 months, either Owner may terminate on 12 months notice; and    
                                                                                
     (d)the head of marketing in the joint marketing company will be a direct   
        report to the CEO.                                                      

     All joint marketing undertaken by the JV will be appropriately ring        
     fenced from the separate marketing activities of the Owners.               
5.Other Marketing Arrangements                                                  
5.1.    Owners will seek to standardise products as soon as practical,         
     provided they can vary their customer contracts on terms reasonably        
     acceptable to them, and provided the Manager can do so on terms            
     reasonably acceptable.                                                     
5.2.    To meet marketing and underlying JV commitments, the Manager (at the   
     direction of the CEO) will initially allocate products between the Owners  
     to reproduce the effect of equal tonnage and equal value allocation.       
     This allocation may result in unequal tonnage, but is intended to result   
in equal value, to the Owners.  The allocation:                            
      (a)    will take into account differences in independently obtained       
        market prices per product to equalise the total market value of         
        products supplied to each Owner;                                        

      (b)    will continue as long as an equalisation/adjustment is required;   
      (c) will be undertaken in conjunction with an independent auditor; and    
      (d)    will use dry metric tonne units and take into account the quality  
of the product to be substituted.                                       
                                                                                
    Annually (or more frequently if the Owners agree), a true up adjustment     
    will be made to ensure the Owners have received equal value, taking into    
account product that could not be sold.  The adjustment mechanism will be   
    specified in the definitive agreements.                                     
6.Expansions                                                                    
 6.1.    If the Owners` demand forecasts exceed expected capacity, the          
Manager may (and will if directed) conduct a Concept/OoM study into        
     brownfield / greenfield expansions (having consulted with the Owners as    
     to its scale and scope) and, subject to outcome, a feasibility study.  If  
     the Owners cannot agree the scope of the expansion, the subject of the     
Concept/OoM study, the Manager will conduct a study into the scope of      
     that expansion which is expected to provide the most annual capacity.      
 6.2.    Either Owner can also propose additional or alternative expansions.    
 6.3.    Feasibility studies will consider costs and include customary          
assumptions.  The expansion proposal must deliver total system capacity    
     (eg mine, infrastructure and ancillaries) sufficient to meet the           
     requirements of the expansion.                                             
 6.4.    If the Owners Council approves a feasibility study, the expansion      
will be funded and capacity shared equally.                                
 6.5.    If the Owners Council agrees on the need for an expansion but does     
     not agree on the expansion pathway (where there is more than one option),  
     the option which has the highest NPV (as determined by the Manager)will    
be selected.                                                               
 6.6.    If only one Owner wants to proceed with the expansion on a sole risk   
     basis, then the expansion will be undertaken by the Manager with that      
     Owner paying all costs (including all capex and fully allocated operating  
costs).  The funding Owner will be entitled to the additional capacity     
     created by this investment.  The expansion proposal must deliver total     
     system capacity (eg mine, infrastructure and ancillaries) sufficient to    
     meet the requirements of the expansion, and:                               
(a)the expanding Owner will compensate the other Owner, at market value,   
        for its share of the underlying in-situ resource, as determined by an   
        independent expert; and                                                 
                                                                                
(b)where the expansion will use existing infrastructure capacity, the JV   
        will charge the sole risking Owner for that capacity on the basis of    
        principles to be agreed in the binding agreements.                      
 6.7.    To sole risk an expansion, the capital expenditure for the project     
must be greater than US$250 million (indexed).                             
 6.8.    All new or potential iron ore acquisitions or investment proposals     
     in WA must be put to the JV by an Owner or the CEO for its assessment.     
     The result of this assessment will then be presented to the Owners.        

     (a)If both Owners want to proceed then the opportunity will be undertaken  
        within the scope of the JV;                                             
                                                                                
(b)If only one Owner wants to proceed then the Manager will operate the    
        assets and the sole risking provisions of 6.6 will apply.               
 6.9.    If one of the Owners acquires a multi commodity company of assets,     
     which owns iron ore assets in WA, the Owner must offer the iron ore        
assets at cost (to be determined by an independent expert) to the JV;      
        (a) If both Owners want to proceed then the opportunity will be         
        undertaken within the scope of the JV;                                  
                                                                                
(b) If only the acquiring Owner wants to proceed then the Manager will     
        operate the assets and the sole risking provisions of 6.6 will apply.   
                                                                                
7.Other provisions                                                              
7.1.    Owners will be free to sell down their JV interests without any pre-   
     emptive rights or change of control restrictions.  Neither Owner can sell  
     or encumber, subject to 1.6(c) any underlying assets or underlying JV      
     interests.                                                                 
Minor disposals (where Owner sells less than 17% and its effective economic    
 interest in the JV interest remains above 25%)                                 
 7.2.    The following principles apply to these disposals:                     
     (a)the selling Owner will remain as the Owner with all JV rights and       
obligations;                                                            
                                                                                
     (b)third party purchaser would receive an economic interest only, with no  
        rights to tonnes;                                                       

     (c)third party purchaser would derive its interest only from the relevant  
        Owner (eg it would not have the ability to make annual production       
        elections or sole risk); and                                            

     (d)minority protection rights would be limited to those negotiated         
        between the third party and the relevant Owner, to be taken into        
        account by that Owner in exercising its vote.                           

 Disposal of substantial interest (where Owner sells more than 17% to one       
 party and its JV interest remains above 25%)                                   
                                                                                
7.3.    7.2 will apply except that the purchaser would be entitled to          
     receive a proportionate share of tonnes.                                   
                                                                                
 Major disposals (where Owners` JV interest is below 17% and new Owner          
acquires more than 25% in the JV)                                              
                                                                                
 7.4.    The following principles would apply to these disposals:               
                                                                                
(a)third party purchaser will succeed to the JV arrangements and assume    
        all rights and obligations of the selling Owner and become the Owner;   
                                                                                
     (b)the selling Owner would retain an economic interest only, with no       
rights to tonnes;                                                       
                                                                                
     (c)the selling Owner would derive its interest only from the purchaser as  
        a new Owner (eg it would not have the ability to make annual            
production elections or sole risk); and                                 
                                                                                
     (d)minority protection rights would be limited to those negotiated         
        between the selling Owner and the purchaser (as new Owner), to be       
taken into account by that purchaser in exercising its vote.            
                                                                                
     (e)The new Owner must acquire the underlying assets that underpin that     
        Owner`s contribution to the JV.                                         
7.5     In the case of any matters involving a related party transaction       
     (including transactions with either Owner) the matter will require the     
     support of participants together holding an effective economic interest    
     of more than 75%.                                                          
7.6The right to vote on the Owners Council can only be exercised by an Owner   
     that has an effective economic interest of more than 25% of the JV.  If    
     there is only one Owner entitled to vote, then the other Owners who        
     derived their interest from the other original Owner, will have a right    
to receive tonnes.                                                         
 Conditions precedent                                                           
 7.7.    Pre-conditions for closing are the ability to satisfy key regulatory   
     requirements (being relevant anti-trust regulators, ATO, the WA            
Government and FIRB), requisite shareholder approvals, and reasonable      
     representations and warranties.  The parties agree to use reasonable       
     endeavours to satisfy the preconditions for closing.  (Confidential        
     provision deleted.)                                                        
7.8.    (Confidential provision deleted.)                                      
 Other                                                                          
 7.9.    Any financial true up adjustments required  to equalise the            
     interests of the Owners for the purpose of tax accounting within the JV    
will be adjusted as provided for in the binding agreements (with the       
     assistance of an independent auditor) to be effected by either tracking    
     notes or other terms.                                                      
 7.10.   Each Owner to bear their own JV formation costs.                       
7.11.   (Confidential provision deleted.)                                      
 7.12.   The JV agreement will include measures to maximize the security of     
     each party`s economic interest, including:                                 
     (a)financial obligations secured via a first ranking cross charge,         
subject to any existing or future underlying JV cross charges or any    
        JV or Owner negative pledge;                                            
                                                                                
     (b)failure to pay a called sum gives rise, subject to appropriate grace    
periods at the election of the non defaulting participant, to dilution  
        based on fair market value of the JV before the default, taking into    
        account the amount of the default or a buy out right at fair market     
        value; and                                                              

     (c)voting rights of defaulting party on Owners Council suspended.          
                                                                                
 7.13.    BHP Billiton warrants that RGP5 will be constructed in accordance     
with a scope of work provided by BHP Billiton and that the costs of        
     constructing RGP5 in accordance with the scope and achieving practical     
     completion will not exceed US$4.8bn (JV`s 85% share).  BHP Billiton will   
     be liable for 100% of all costs above this amount.  BHP Billiton will use  
best endeavours to achieve practical completion by 31 December 2011.       
 7.14.    From the date of agreement until completion, BHP Billiton and Rio     
     Tinto will carry on their respective iron ore operations in the ordinary   
     course.  Neither Owner may sell or encumber in any way any underlying      
assets or JV interests prior to completion.  Sustaining capex will be      
     identified and the parties will have an obligation to progress.  A list    
     of specific expansion programmes will also be identified, which the        
     parties will also have an obligation to progress.  In addition either      
party may initiate / progress any additional expansions.  If the other     
     party does not wish to take up its share then the expansion will proceed   
     and post completion would be treated as a sole risk expansion.             
 7.15.    An implementation structure will be put in place to operate between   
the date of the Agreement and closing.  The structure will comprise two    
     groups made up of:                                                         
     (i)    the designated future members of the Owners` Council; and           
     (ii)    the designated future members of the Senior Executive Team and     
other senior members of the future management team.                     
                                                                                
     These groups will (subject to compliance with all applicable competition   
     laws) address the efficient implementation of the transaction and          
sharing of information relating to production including expansions (that   
     will affect the JV post-completion).  The management group will recommend  
     the systems, standards and procedures to be implemented by the JV in       
     accordance with item 3.9 and will put its proposals to the future members  
of the Owners Council for approval.  The implementation structure will     
     also ensure that the Manager can assume operational responsibility for     
     the JV at completion.                                                      
 7.16.   Nothing in this document is intended to create binding legal           
obligations.                                                               
 7.17.   A limited due diligence will be conducted prior to entry into the      
     binding agreements.                                                        
 7.18.   The parties acknowledge that the terms of this document will govern    
the preparation of the contents of the more detailed implementation and    
     definitive agreements.                                                     
(1)  Change  in cash, debt and distribution policies will be prescribed  by  the
agreements.  Changes would be agreed by both Owners.
