companies were a single unified economic entity and for that purpose the directors of each company shall take into account in the exercise of their powers the interests of the shareholders of the other; and
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|--- | -------------------------------------------------

and BHP and Billiton agree to pursue, and agree to procure

3.    Equalisation

3.1    DLC Equalisation Principles

Subject to Clause 3.2, the following principles shall be observed in relation to the rights of the BHP Ordinary Shares and the Billiton Ordinary Shares:



|(a) | the Equalisation Ratio shall govern the economic rights of one BHP Ordinary Share relative to one Billiton Ordinary Share (and vice versa) and the relative voting rights of one BHP Ordinary Share and one Billiton
Ordinary Share on Joint Electorate Actions so that, where the Equalisation Ratio is 1:1, a holder of one BHP Ordinary Share and a holder of one Billiton Ordinary Share shall, as far as practicable:
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | receive equivalent economic returns; and
| | --- | ----------------------------------------



| | (ii) | enjoy equivalent rights as to voting in relation to Joint Electorate Actions,
| | ---- | -----------------------------------------------------------------------------

and otherwise
such returns and rights as between a BHP Ordinary Share and a Billiton Ordinary Share will be in proportion to the then prevailing Equalisation Ratio;



9



---

DLC Structure Sharing Agreement





|(b) | where an Action by BHP or Billiton is proposed such that the Action would result in the ratio of the economic returns on, or voting rights (in relation to Joint Electorate Actions) of, a BHP Ordinary Share to a Billiton
Ordinary Share not being the same as the then prevailing Equalisation Ratio, or which would benefit the holders of Ordinary Shares in one party relative to the holders of Ordinary Shares in the other party, then:
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | unless the Boards of BHP and Billiton determine that it is not appropriate or practicable, a Matching Action shall be undertaken; or
| | --- | ------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | if no Matching Action is to be undertaken, an appropriate adjustment to the Equalisation Ratio shall be made,
| | ---- | -------------------------------------------------------------------------------------------------------------

in order to ensure that there is equitable treatment (having regard to the then prevailing Equalisation Ratio) as between the holder of one BHP
Ordinary Share and the holder of one Billiton Ordinary Share. However, if the Boards of BHP and Billiton determine that it is not appropriate or practicable to undertake a Matching Action and that an adjustment to the Equalisation Ratio would not be
appropriate or practicable in relation to an Action, then such Action may be undertaken provided it has been approved as a Class Rights Action.

3.2    Qualifications

For the
purposes of the DLC Equalisation Principles, save where expressly otherwise provided:



|(a) | in relation to any Action, the economic return to the holders of BHP Ordinary Shares or Billiton Ordinary Shares shall be calculated before deduction of Withholding Tax and disregarding any Tax payable by or on behalf
of, or any Tax Benefit arising to, such holders;
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | Where an Action:
|--- | ----------------



| | (i) | has not been approved as a Class Rights Action;
| | --- | -----------------------------------------------



| | (ii) | in the absence of such approval, would require a Matching Action or adjustment to the Equalisation Ratio by virtue of Clause 3.1(b); and
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | the Boards of BHP and Billiton consider that the effect of such Action upon the holder of a BHP Ordinary Share relative to its effect upon a holder of a Billiton Ordinary Share is not material (as defined below),
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

then (subject to the next sentence) there shall be no requirement for a Matching Action, an adjustment to the Equalisation
Ratio or approval as a Class Rights Action in respect of such Action (an Unadjusted Action). However, in considering the application of the DLC Equalisation Principles to any Action the Boards of BHP and Billiton shall take into
account the effect of all prior Unadjusted Actions in deciding whether a Matching Action, an adjustment to the Equalisation Ratio or approval as a Class Rights Action is appropriate and if any adjustment is made it shall take into account all such
prior Unadjusted Actions. For the purposes of this Clause, the effect of an Action is not material if both:



| | (i) | the costs to BHP and Billiton of taking a Matching Action or seeking approval as a Class Rights Action would be, in the opinion of the Boards of BHP and Billiton, disproportionate to the effect of such Action upon the
holders of BHP Ordinary Shares or Billiton Ordinary Shares (as the case may be) for whose benefit a Matching Action would otherwise (in the absence of an adjustment to the Equalisation Ratio or approval as a Class Rights Action) be required; and
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the adjustment that would be required to be made to the Equalisation Ratio would result in an adjustment to the relevant element of the Equalisation Ratio of less than 0.1%;
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



10



---

DLC Structure Sharing Agreement





|(c) | the Boards of BHP and Billiton shall have no obligation to take into account any fluctuations in exchange rates or in the market value of any securities or any other changes in circumstances arising after the time at
which the Boards of BHP and Billiton make a determination as to the form and value of any Matching Action or the calculation of any adjustment to the Equalisation Ratio; and
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(d) | there shall be no need for the Boards of BHP and Billiton to make any adjustment to the Equalisation Ratio or to do or omit to do any other thing as a result of the dividend, voting or other rights of any shareholder
being suspended or curtailed pursuant to any provision of either Constitution.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

3.3    Cash Dividends



|(a) | Subject to Clauses 3.3(b) and 3.4, if the Action proposed by either party is the payment of a cash dividend to its Ordinary Shareholders, then, notwithstanding that the provisions of Clause 3.2(b) may apply so as not to
require any Matching Action, a Matching Action shall be taken in the form of a cash dividend by the other party to its Ordinary Shareholders (a Matching Dividend).
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | Clause 3.3(a) shall not restrict either partys ability to offer to its holders of Ordinary Shares the ability to elect to subscribe for further Ordinary Shares at market value in lieu of receiving the whole or any
part of a cash dividend.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

3.4    Equalisation Payment

If either party is prohibited by Applicable Regulation or is otherwise unable to declare, pay or otherwise make all or any portion of a Matching Dividend, BHP
and Billiton shall, so far as it is practicable to do so, enter into such transactions with each other as the Boards of BHP and Billiton agree to be necessary or desirable so as to enable both to pay dividends as nearly as practicable at the same
time in accordance with the other provisions of this Clause 3.

3.5    Circumstances not requiring Matching Action etc

No Matching Action, adjustment to the Equalisation Ratio or approval as a Class Rights Action is required:



|(a) | in respect of any Action which would not result in the ratio of the economic returns on, or voting rights (in relation to Joint Electorate Actions) of, a BHP Ordinary Share to a Billiton Ordinary Share not being the
same as the then prevailing Equalisation Ratio (and vice versa), or which would not benefit the holders of Ordinary Shares in one party relative to the holders of Ordinary Shares in the other party;
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | where a Matching Action, adjustment to the Equalisation Ratio or approval as a Class Rights Action is not required by virtue of Clause 3.2(b);
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------



|(c) | in relation to the issue of securities or the granting of rights over securities by either BHP or Billiton pursuant to a scheme for encouraging or facilitating the holding of shares or other securities in the relevant
company by or for the benefit of directors or former directors or bona fide employees or former employees of either BHP or Billiton or any of their respective Subsidiaries;
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(d) | in relation to an issue of any securities in either BHP or Billiton other than an offer by way of rights;

|(b) | Unless the Boards of BHP and Billiton decide otherwise, any matter which by Applicable Regulation or by virtue of the provisions of the BHP Constitution or the Billiton Memorandum and Articles requires approval of the
shareholders of BHP or Billiton as the case may be and which is not a Class Rights Action or a Joint Electorate Action, requires the approval of the holders of BHP Ordinary Shares only or the approval of the holders of Billiton Ordinary Shares only
(as the case may be).

6.5    Procedural Resolutions

Where any procedural resolution is to be voted on at a meeting of shareholders at which a Joint Electorate Action is to be considered, such procedural

8.1    One party insolvent

Subject to

|--- | --------------------------------------------------------------------------------------



| | (i) | irrevocably to offer to the holders of Ordinary Shares in IS Party on the Notice Date in consideration for their Ordinary Shares in IS Party such number of Ordinary Shares in S Party pro rata to their holdings of
Ordinary Shares in IS Party as is required to ensure that, after such issue, Economic Equivalence is achieved; or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | to pay to holders of Ordinary Shares in IS Party on the Notice Date an amount equal to that proportion of S Partys Market Capitalisation as at the Notice Date such that the amount paid and the balance remaining
ensure that Economic Equivalence is achieved.
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(d) | Unless S Party has exercised its rights under Clause 8.1(c), then, subject to Clause 8.1(e), S Party must:

| | (ii) | within 1 month thereafter pay to IS Party an amount equal to that proportion of S Partys total Market Capitalisation on the date all payments have been made pursuant to Clause 8.1(d)(i) such that the amount paid
and the balance remaining ensure that Economic Equivalence is achieved.
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(e) | Payments under this Clause 8.1 shall only be made by S Party to the extent that after making such payment there will remain available to S Party sufficient assets to pay all its debts as and when they become due and

8.2    Both parties insolvent

If each party has provided the other with an Insolvency Notice and if:



|(a) | either party has surplus assets available for distribution to the holders of its Ordinary Shares after payment of all debts due and payable; and
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | the ratio of the surplus attributable to each BHP Ordinary Share to the surplus attributable to each Billiton Ordinary Share would otherwise not equal the Equalisation Ratio,
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

then one party must as soon as practicable pay to the other (where possible) an amount which results in that ratio equalling the Equalisation Ratio.

8.3    Definitions and Interpretation

In this Clause 8:



|(a) | Economic Equivalenceshall be determined before deduction of any amount in respect of Tax which may be deducted or withheld in respect of any payment to a holder of Ordinary Shares and
disregarding any Tax payable by or on behalf of, or any Tax Benefit arising to, a holder of Ordinary Shares.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | Market Capitalisation, in relation to S Party, means the total value of all its issued Ordinary Shares (determined by reference to the trading price of those shares on the close of trading on
the relevant day on the stock exchange on which it has its primary listing);
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(c) | Notice Datemeans the date a party receives or is deemed to receive an Insolvency Notice from the other party;
|--- | -------------------------------------------------------------------------------------------------------------

DLC Structure Sharing Agreement





|(e) | The surplus assets of a party available for distribution to holders of Ordinary Shares shall, for the purposes of Clause 8.2, be calculated:
|--- | --------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | before deduction of any amount in respect of Tax which may be deducted or withheld from the distribution by or on behalf of the party paying or making the distribution; but
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | net of any Tax payable by that party on the distribution to holders of Ordinary Shares excluding, for the avoidance of doubt, any Tax within (i) above; and
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------



|(f) | Where a party pays an amount to the other party, the calculation of the amount of the payment shall take account of any Tax payable on the making or receipt of, or any withholding or deduction in respect of Tax arising
on, any payment, after allowing for any offsetting Tax Benefits.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

9.    Termination

|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | by a party by notice, at any time after it has fulfilled its obligations under Clause 8; or

|(c) | if termination has been approved as a Class Rights Action, in the manner specified in the relevant resolution. However, BHP or Billiton may only seek such approval if the Boards of BHP and Billiton agree on the terms

Principles.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

10.    Personal rights only

For the avoidance of doubt, Clauses 3, 8 and 9 are personal rights only. They do not, and are not intended to, create any proprietary right (including any
proprietary right in any member or creditor of BHP or Billiton). These undertakings are not assignable, and cannot be subject to a mortgage, charge, pledge, encumbrance or other security interest. These undertakings do not survive any termination of
this Agreement. It is fundamental to the agreement of each of BHP and Billiton to give these undertakings that they should be relied on solely by the other, and it is fundamental to the agreement of each of BHP and Billiton to accept these
undertakings that they should be performed solely by the other.
