Impact of South32 Demerger on Shareplus and Loan Shares This communication describes the impact of the proposed Demerger of South32 by BHP Billiton in May 2015 for participants in BHP Billiton’s all-employee share plan, Shareplus, and holders of Loan Plan shares. If the Demerger does not proceed, then the operation of the plans will remain as per the original terms and conditions. All dates are indicative only and are subject to change. Information about the Demerger of South32 by BHP Billiton can be found on the employee portal. Please click on the box below that applies to you. I am continuing with BHP Billiton or I will be part of South32 shareplus the all employee share plan < Back I am continuing with BHP Billiton Shareplus 2012 Shareplus 2013 and Shareplus 2014 Shareplus 2015 Shares you have with the Shareplus Nominee Shareplus timeline for employees continuing with BHP Billiton Loan Shares Solium contact details Shareplus terminology Shareplus 2012 Matched Shares under Shareplus 2012 will vest on 7 April 2015 as per the normal schedule, and will be provided in BHP Billiton shares as usual. Further communications on the vesting of Shareplus 2012 will be provided in late March 2015. In all countries other than Australia, Indonesia and Singapore, BHP Billiton is required to withhold taxes on this share income and as a result some of your Matched Shares will be sold and the proceeds remitted by BHP Billiton to the relevant tax authority to cover these taxes. For Singaporean employees, your share income will be reported in your December 2015 IR8A. Australian employees will be sent an Australian ESS Statement, including the share income, in July 2015. Your 2012 Acquired Shares are being held by the Shareplus Nominee, and after the vesting your Matched Shares will also be held by the Shareplus Nominee. As in prior years, you can choose to sell any of these shares at any time, but you should consider the information in the tab Shares you have with the Shareplus Nominee before you decide whether you want to sell them prior to the Demerger, or hold them during the Demerger. shareplus the all employee share plan < Back I am continuing with BHP Billiton Shareplus 2012 Shareplus 2013 and Shareplus 2014 Shareplus 2015 Shares you have with the Shareplus Nominee Shareplus timeline for employees continuing with BHP Billiton Loan Shares Solium contact details Shareplus terminology Shareplus 2013 and Shareplus 2014 Shareplus 2013 and Shareplus 2014 will vest as per the normal schedule in April 2016 and April 2017 respectively, and will be provided in the form of BHP Billiton shares. Any Acquired Shares that you have purchased while participating in these plans will be eligible to receive South32 shares as part of the Demerger as described in the tab Shares you have with the Shareplus Nominee. Unvested Matched Shares will not be eligible to receive shares in South32 as part of the Demerger. However, BHP Billiton’s share price after the Demerger is expected to be lower than before the Demerger, because some of the BHP Billiton Assets will be part of South32 after the demerger. Holders of Unvested Matched Shares will therefore receive an uplift in the number of BHP Billiton shares provided upon vesting of Shareplus 2013 and Shareplus 2014 Matched Shares. This uplift will reflect the reduction in BHP Billiton’s share price post Demerger, and will keep the total value of your entitlement whole as at the date of the Demerger. The shares provided in respect of the uplift will be BHP Billiton shares. If you have participated in Shareplus 2013 and also in Shareplus 2014, you will receive an Uplift Award 2013 and an Uplift Award 2014. The number of awards in each uplifted award will be calculated using the formula below, rounded up to a whole number of awards: BHP Billiton Value + South32 Value BHP Billiton Value -1 Number of Unvested x Matched Shares held before the demerger The “Value” is based on the volume weighted average price of shares on the first five days following South32’s listing on the ASX on or around 18 May 2015 (subject to any adjustment that the BHP Billiton Board considers appropriate in the event that the relevant five-day VWAP is reasonably determined by the BHP Billiton Board to have been distorted by an unforeseen temporary market event unrelated to either BHP Billiton or South32). The formula above ensures that even though Unvested Matched Shares will not be eligible to receive shares in South32 as part of the Demerger you will not be disadvantaged by the Demerger.

Shareplus 2012 Example Shareplus 2013 and Shareplus 2014 Sally holds the following: Shareplus 2015 - 100 Acquired Shares and 100 Unvested Matched Shares from Shareplus 2013 and Shares you have with the Shareplus Nominee - 75 Acquired Shares and 75 Unvested Matched Shares from Shareplus 2014. Shareplus timeline for employees continuing with BHP Billiton If the BHP Billiton Value was $30 and the South32 Value was $3, then Sally would receive the following Uplift Awards: In relation to Shareplus 2013, Sally will receive an Uplift Award 2013 of: Loan Shares $30 + $3 $30 -1 x 100 = 10 awards Solium contact details In relation to Shareplus 2014, Sally will receive an Uplift Award 2014 of: Shareplus terminology $30 + $3 $30 As the two uplift allocations are legally considered to be new employee equity offers, a participant notification including all of the terms and conditions of the allocations (which are the same as those for the related Shareplus awards) and relevant tax information will be loaded to Shareworks. If for any reason you do not want to receive the Uplift Awards, you can choose to not accept the awards, but you will not receive any other compensation for the reduction in the value of your BHP Billiton Unvested Matched Shares as a result of the Demerger. Example summary Sally’s holdings post demerger will be: Shareplus 2013 Acquired Shares 100 Unvested Matched Shares 100 Uplift Award 10 Shareplus 2014 -1 x 75 = 8 awards The Uplift Award 2013 will vest in April 2016 and the Uplift Award 2014 will vest in April 2017, at the same time as the related Unvested Matched Shares from Shareplus 2013 and Shareplus 2014. The two uplift allocations will be made in late May 2015, and a notification from Solium will be sent to employees once the awards have been loaded to the Solium website - Shareworks.

For employees continuing with South32, the Unvested Matched Shares from Shareplus 2013 and Shareplus 2014 will instead vest on or around 7 May 2015 following shareholder approval of the Demerger. By vesting the awards on this date, the ordinary BHP Billiton shares that will arise from the vesting (after sales for withholding taxes as described below) will be held by the Shareplus Nominee on your behalf at the time of the Demerger and will be eligible for South32 shares (as described in the tab Shares that you have with the Shareplus Nominee). Withholding taxes on vesting awards As is usual for any Shareplus vesting, for all employees other than those in Australia, Indonesia and Singapore, BHP Billiton is required to withhold taxes on the share income from the vesting of Matched Shares.

For Singaporean employees, your Share Income will be reported in your December 2015 IR8A. Australian employees will be sent an Australian ESS Statement including the Share Income in July 2015. Tax guides for each country are available on Shareworks and we strongly urge you to read the guides and be aware of your tax obligations.

South32 shares are provided to the Shareplus Nominee on 25 May, and allocated to Sally’s Shareworks account. The number of BHP Billiton and South32 shares Sally would receive is as follows: Acquired Shares Unvested Matched Shares Matched Shares sold for taxes Vested Matched Shares after tax Shareplus 2013 100 100 100 x 30% = 30 100 - 30 = 70 Shareplus 2014 75 75 75 x 30% = 23 75 - 23 = 52 Total BHP Billiton ordinary shares 175 - - 122 Total South32 ordinary shares 175 - - 122 Note: Australian, Indonesian and Singaporean employees would not have tax withheld during May 2015 in the above example.
