Information Relating to the US Offer for Rio Tinto Plc

BHP Billiton plans to register the offer and sale of securities it would issue to Rio Tinto Plc US shareholders and Rio Tinto Plc ADS holders by filing with the U.S. Securities and Exchange Commission (the “SEC”) a Registration Statement (the “Registration Statement”), which will contain a prospectus (“Prospectus”), as well as other relevant materials. No such materials have yet been filed. This communication is not a substitute for any Registration Statement or Prospectus that BHP Billiton may file with the SEC.

U.S. INVESTORS AND U.S. HOLDERS OF RIO TINTO PLC SECURITIES AND ALL HOLDERS OF RIO TINTO PLC ADSs ARE URGED TO READ ANY REGISTRATION STATEMENT, PROSPECTUS AND ANY OTHER DOCUMENTS MADE AVAILABLE TO THEM AND/OR FILED WITH THE SEC REGARDING THE POTENTIAL TRANSACTION, AS WELL AS ANY AMENDMENTS AND SUPPLEMENTS TO THOSE DOCUMENTS, WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION.

Investors and security holders will be able to obtain a free copy of the Registration Statement and the Prospectus as well as other relevant documents filed with the SEC at the SEC’s website (http://www.sec.gov), once such documents are filed with the SEC. Copies of such documents may also be obtained from BHP Billiton without charge, once they are filed with the SEC.

Information for US Holders of Rio Tinto Limited Shares

BHP Billiton Limited is not required to, and does not plan to, prepare and file with the SEC a registration statement in respect of the Rio Tinto Limited Offer. Accordingly, Rio Tinto Limited shareholders should carefully consider the following:

The Rio Tinto Limited Offer will be an exchange offer made for the securities of a foreign company. Such offer is subject to disclosure requirements of a foreign country that are different from those of the United States. Financial statements included in the document will be prepared in accordance with foreign accounting standards that may not be comparable to the financial statements of United States companies.

Information Relating to the US Offer for Rio Tinto Plc and the Rio Tinto Limited Offer for Rio Tinto shareholders located in the US

It may be difficult for you to enforce your rights and any claim you may have arising under the U.S. federal securities laws, since the issuers are located in a foreign country, and some or all of their officers and directors may be residents of foreign countries. You may not be able to sue a foreign company or its officers or directors in a foreign court for violations of the U.S. securities laws. It may be difficult to compel a foreign company and its affiliates to subject themselves to a U.S. court’s judgment.

You should be aware that BHP Billiton may purchase securities of either Rio Tinto Plc or Rio Tinto Limited otherwise than under the Offers, such as in open market or privately negotiated purchases.

Public information

Information about Rio Tinto and Alcan Inc. included in the information contained in this part of the website is based on public information which has not been independently verified. Certain statistical and other information about BHP Billiton included in the information contained in this part of the website has been sourced from publicly available third party sources. As such it presents the views of those third parties, but may not necessarily correspond to the views held by BHP Billiton.

Forward-looking statements

It is possible that this part of the website could or may contain forward looking statements that are based on current expectations or beliefs, as well as assumptions about future events. Forward-looking statements include any synergy statements and, without limitation, other statements typically containing words such as “intends”, “expects”, “anticipates”, “targets”, “plans”, “estimates” and words of similar import. Such forward-looking information includes, without limitation, the statements as to the impact of the proposed combination on revenues, costs and earnings. Because of their very nature, they are subject to a number of known and unknown risks and uncertainties that could cause actual results, performance and achievements to differ materially from any expected future results, performance or achievements expressed or implied by such forward-looking statements. Such forward-looking statements are based on numerous assumptions regarding BHP Billiton’s present and future business strategies and the environments in which BHP Billiton and Rio Tinto will operate in the future and such assumptions may or may not prove to be correct.

There are several factors which could cause actual results or performance to differ materially from those expressed or implied in the forward looking statements. Factors that could cause actual results or performance to differ materially from those described in the forward looking statements include, but are not limited to, the presence of a competitive proposal in relation to Rio Tinto, satisfaction of any conditions to the Offers, including the receipt of required regulatory and anti-trust approvals, Rio Tinto’s willingness to enter into any proposed transaction, the successful completion of the Offers, as well as additional factors, such as BHP Billiton’s ability to

successfully combine the businesses of BHP Billiton and Rio Tinto and to realise expected synergies from that combination, changes in global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax rates, future business combinations or dispositions and the outcome of litigation and government actions. Additional risks and factors that could cause BHP Billiton results to differ materially from those described in the forward-looking statements can be found in BHP Billiton’s filings with the SEC, which are available at the SEC’s website (http://www.sec.gov). Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward-looking statements. The information which is contained in this part of the website is subject to change without notice and BHP Billiton expressly disclaims any obligation (except as required by law, the Listing Rules of ASX Limited or the rules of the UK Listing Authority and the London Stock Exchange) or undertaking to disseminate any updates or revisions to any forward looking statement contained in this part of the website, regardless of whether those statements are affected as a result of new information, future events or otherwise.
