Certain statements in this presentation are forward-looking statements.  The forward-looking statements include statements regarding contribution synergies, future cost savings, the cost and timing of development projects, future production volumes, increases in production and infrastructure capacity, the identification of additional mineral Reserves and Resources and project lives and,without limitation, other statements typically containing words such as "intends", "expects", "anticipates", "targets", "plans", "estimates" and words of similar import. These forward-looking statements speak only as at the date of this presentation.  These statements are based on current expectations and beliefs and, by their nature, 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.  The 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 a number of factors that 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, BHP Billiton's ability to successfully combine the businesses of BHP Billiton and Rio Tinto and to realise expected synergies from that combination, the presence of a competitive proposal in relation to Rio Tinto, satisfaction of any conditions to any proposed transaction, including the receipt of required regulatory and anti-trust approvals, Rio Tinto’s willingness to enter into any proposed transaction, the successful completion of any transaction, as well as additional factors such as changes in global, political, economic, business, competitive, market or 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 US Securities and Exchange Commission (the "SEC"), including BHP Billiton's Annual Report on Form 20-F for the fiscal year-ended June 30, 2007, and Rio Tinto’s filings with the SEC, including Rio Tinto’s Annual Report on Form 20-F for the fiscal year-ended December 31, 2007, 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 and opinions expressed in this presentation are subject to change without notice and BHP Billiton expressly disclaims any obligation (except as required by law or the rules of the UK Listing Authority and the London Stock Exchange, the UK Takeover Panel, or the listing rules of ASX Limited) or undertaking to disseminate any updates or revisions to any forward-looking statements contained herein to reflect any change in BHP Billiton’s expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based.

Slide 3 Slide Disclaimer (continued) No statement concerning expected cost savings, revenue benefits (and resulting incremental EBITDA) and EPS accretion in this presentation should be interpreted to mean that the future earnings per share of the enlarged BHP Billiton group for current and future financial years will necessarily match or exceed the historical or published earnings per share of BHP Billiton, and the actual estimated cost savings and revenue benefits (and resulting EBITDA enhancement) may be materially greater or less than estimated. 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 SEC a Registration Statement (the “Registration Statement”), which will contain a prospectus (the “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 b e 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.
