 debt securities, interest withholding tax should not be payable in relation to the guarantee payments. As section 128F is not intended to be satisfied in respect of the RTP Debt Securities or RTI Debt Securities, subject to the comments below, interest withholding tax may be payable in relation to payments under the guarantee for those RTP Debt Securities or RTI Debt Securities.

IWT will not be payable on payments by Rio Tinto plc pursuant to its guarantee of RTP Debt Securities, RTL Debt Securities or RTI Debt Securities to United States holders provided Rio Tinto plc does not carry on business in Australia at or through an Australian Establishment (which is not presently expected to be the case).

#### Gains on Disposal
Under existing Australian law, United States holders of RTL Debt Securities, RTP Debt Securities or RTI Debt Securities will not be subject to Australian income tax on gains arising from a disposal of debt securities (including a disposal by way of redemption) provided that the gains do not have an Australian source.

The source of any gain on disposal of debt securities will depend on the factual circumstances of the disposal. Where the disposal occurs by way of a sale to a third party, then provided the debt securities are acquired and sold pursuant to contractual arrangements entered into and concluded outside Australia, and the seller and the purchaser are non-residents of Australia and do not have Australian Establishments, a gain will not be regarded as having an Australian source. Where disposal occurs by way of redemption by the issuer then, in the absence of special circumstances, a gain on redemption will not be regarded as having an Australian source.

There are specific rules (Section 128AA of the Australian Tax Act) that can apply to treat a portion of the sale price of debt securities as interest for withholding tax purposes. These rules apply when certain debt securities originally issued at a discount or with maturity premium, generally speaking, or which do not pay interest at least annually are sold to:

•

an Australian resident that does not derive the sale price in carrying on business through a permanent establishment outside Australia; or

•

a non-resident of Australia who derives the sale price in carrying on business at or through an Australian Establishment.
