|2.1 |  | Purpose
|--- |  | -------



| |  | The purpose of this clause 2 is to record the fundamental principle underlying the agreement between the Alumina Limited Group and the WMC Resources Group as to the intended
economic and legal effect of the Demerger. Subsequent clauses in this deed and in the other Transaction Documents are intended to give effect to the Demerger Principle. To the extent that there is any ambiguity in those provisions, they are to be
interpreted in light of the Demerger Principle.
| |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (i) |  | until the Demerger Date WMC Resources was a wholly owned Subsidiary of Alumina Limited;
| | --- |  | ---------------------------------------------------------------------------------------



| | (ii) |  | until the Demerger Date all the issued shares in WMC Resources were beneficially owned by Alumina Limited; and
| | ---- |  | --------------------------------------------------------------------------------------------------------------

| | effect from the Demerger Date in consideration for the application of those shareholders entitlements to the Capital Reduction and the Demerger
Dividend,
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------



following the Demerger, the
parties intend as a fundamental principle of the Demerger that, as between the Alumina Limited Group on the one hand and the WMC Resources Group on the other hand, on and from the Accounting Effective Date the WMC Resources Group will have the
entire economic benefit (including of profits booked to WMC Resources Group Members on and from the Accounting Effective Date) and risk of the Demerged Businesses and Companies as if the WMC Resources Group had owned and operated the Demerged
Businesses and Companies at all times.



| | (b) |  | Accordingly, if at any time after the Demerger Date:
| | --- |  | ----------------------------------------------------



| | (i) |  | there are any assets within the Alumina Limited Group that, prior to the Demerger Date, predominantly related to, or were required for the ownership or operation of, any of WMC
Resources, the Demerged Businesses, the Companies or the Former WMC Resources Businesses, the WMC Resources Group is entitled to the use and benefit of those assets (as provided for in this deed); and
| | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) |  | a Liability or Loss arises or is incurred directly or indirectly by an Alumina Limited Group Member, and that liability relates to the ownership (whether direct or indirect) or
operation by Alumina Limited or any Alumina Limited Group Member of WMC Resources, the Demerged Businesses, the Companies or the Former WMC Resources Businesses at any time, WMC Resources must indemnify and must procure that the relevant WMC
Resources Group Members indemnify the Alumina Limited Group or relevant Alumina Limited Group Member in respect of that Liability or Loss.
| | ---- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) |  | Correspondingly, if at any time after the Demerger Date:
| | --- |  | --------------------------------------------------------



| | (i) |  | there are assets within the WMC Resources Group that, prior to the Demerger Date, predominantly related to, or were required for the ownership or operation of, an Alumina Limited
Group Member or a business carried on by an Alumina Limited Group Member (other than the Demerged Businesses or a Former WMC Resources Business) or a Former Alumina Limited Business, the Alumina Limited Group is entitled to the use and benefit of
those assets (as provided for in this deed); and
| | --- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) |  | a Liability or Loss arises or is incurred directly or indirectly by a WMC Resources Group Member, and that liability relates to the ownership (whether direct or
indirect) or operation by WMC Resources or any WMC Resources Group Member of an asset, business or company transferred by a WMC Resources Group Member to an Alumina Limited Group
