This presentation is for information purposes only and does not constitute or form part of any offer for sale or issue of any securities or an offer or invitation to purchase or subscribe for any such
securities, nor shall it or any part of it be relied on in connection with, any contract or investment decision, nor does it constitute a proposal to make a takeover bid or the solicitation of any vote
or approval in any jurisdiction, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the
securities laws of any such jurisdiction (or under an exemption from such requirements).  No offering of securities shall be made into the United States except pursuant to registration under the
US Securities Act of 1933, as amended, or an exemption therefrom.  Neither this presentation nor any copy of it may be taken or transmitted or distributed or redistributed (directly or indirectly)
in Japan or Malaysia.  The distribution of this document in other jurisdictions may be restricted by law and persons into whose possession this document comes should inform themselves about,
and observe, any such restrictions. 
This presentation is directed only at persons who (i) are persons falling within Article 49(2)(a) to (d) ("high net worth companies, unincorporated associations etc.") of the Financial Services and
Markets Act 2000 (Financial Promotion) Order 2005 (as amended) (the "Order") or (ii) have professional experience in matters relating to investments falling within Article 19(5) of the Order or
(iii) are outside the United Kingdom (all such persons being referred to as "relevant persons").  This presentation must not be acted on or relied on by persons who are not relevant persons. 
Certain statements in this presentation are forward-looking statements (including 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 statements are based on current expectations
and beliefs and 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, expectations and beliefs may or may not prove to be correct 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.
Factors that could cause actual results or performance to differ materially from those expressed or implied 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, and the risk factors discussed in BHP Billiton's and Rio Tinto’s filings with the U.S. Securities and Exchange Commission ("SEC") (including in Annual
Reports on Form 20-F for the most recent fiscal years) which are available at the SEC's website (http://www.sec.gov).  Save 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, BHP Billiton undertakes no duty to update any forward-looking statements in this presentation 


Slide 3
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.
References in this presentation to “$” are to United States dollars unless otherwise specified. 
In connection with the offer and sale of securities BHP Billiton would issue to Rio Tinto plc US shareholders and Rio Tinto plc ADS holders, BHP Billiton has filed with the SEC a Registration
Statement on Form F-4 (the “Registration Statement”), which contains a  preliminary prospectus (the “Prospectus”), and will file additional relevant materials with the SEC.  This
communication is not a substitute for the Registration Statement or the Prospectus that BHP Billiton has filed, or any amendments or supplements to those documents 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 THE REGISTRATION STATEMENT,
THE 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 are 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).  Copies of such documents may also be obtained from BHP Billiton without charge.
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.
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 exchange offer, such as in open market or privately
negotiated purchases.
