On 20 August 2013 we declared a final dividend for the year ended 30 June 2013 of 59 US cents per share.

The currency exchange rate applicable for the dividend payable in South African cents to shareholders on the BHP Billiton Plc branch register is set out below:

The exchange rates applicable to the BHP Billiton dividend being paid in other currencies will be based on the foreign currency exchange rates on the Record Date, being 6 September 2013, and announced to the market on 9 September 2013.

BHP Billiton Plc shareholders registered on the South African section of the register will not be able to dematerialise or rematerialise their shareholdings between the dates of 2 and 6 September 2013, both dates inclusive, nor will transfers between the UK register and the South African register be permitted between the dates of 30 August and 6 September 2013, both dates inclusive.

NOTE: Additional information required by the JSE Listing Requirements

Following the introduction of Dividend Tax in South Africa, the JSE Listing Requirements were amended with effect from 1 April 2012 to require the disclosure of additional information in relation to the dividend payment. The purpose of this note is to provide that additional information.

1. Dividend Tax will be withheld from the amount of the gross final dividend of 91.486875 South African cents per ordinary share paid to shareholders on the South African branch register at the rate of 15 per cent, unless a shareholder qualifies for an exemption.

2. After the Dividend Tax has been withheld, the net dividend will be 518.425625 South African cents per ordinary share.

3. BHP Billiton Plc had a total of 2,112,071,796 ordinary shares in issue (excluding 24,113,658 treasury shares) at the dividend declaration date of 30 August 2013.

4. With specific reference to South Africa, BHP Billiton Plc, as a non-resident, was not subject to the secondary tax on companies (STC) regime which used to be applicable and therefore no STC credits are available for set-off against the Dividend Tax liability on the final dividend. The dividend will be paid out of retained earnings.

5. For the avoidance of doubt, Dividend Tax, and therefore the information provided in this announcement, is of only direct application to shareholders on the South African branch register.

Shareholders on the South African branch register should direct any questions regarding the application of the Dividend Tax to:
