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)
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.
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.

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
exchange
offer, such as in open market or privately negotiated purchases.

Resourcing the Future –
BHP Billiton’s response
BHP Billiton has not been immune from
supply constraint issues
But our scale, global presence and
diversification provides significant
competitive advantages
We are focused on the disciplined
execution of the core strategy
And on pursuing a renewed
organisational focus on simplicity,

Excellent operating and financial results
Long-term demand outlook remains
strong despite some short-term
economic uncertainty
Supply-side constraints are limiting the
