or

must

or
relied

by
persons
who

not

Information
about
Rio
Tinto
is
based
on
public
information
which
has
not
been
independently
verified.
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
("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

None
of
the
statements
concerning
expected
cost
savings,
revenue
benefits
(and
resulting
incremental
EBITDA)
and
EPS
accretion
in
this

should

to
mean
that
the
future
earnings
per

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.

Accordingly,

Such

that
are
different
from
those
of
the

for
you
to
enforce
your
rights
and
any
claim
you
may
have
arising
under

laws,
since

or
its
officers

be
difficult
to

to
subject
themselves

BHP Billiton’s offer to acquire Rio Tinto


Slide 19
Background to the offer
Early 2007:  BHP Billiton discussed a merger of equals. This concept was rejected
by Rio Tinto
1 November 2007:  BHP Billiton made a confidential proposal to combine the
companies.  Rio Tinto rejected the proposal and refused to enter
discussions
8 November 2007:  BHP Billiton confirmed it had approached Rio Tinto with a proposal
12 November 2007:  BHP Billiton announced the proposal following
market speculation. 
Since then:
Global roadshow has indicated a clear understanding of the industrial logic of the
combination
Rio Tinto has refused to engage to discuss the proposal
21 December 2007:  BHP Billiton required to “put up or shut up”
by 6 February 2008
1 February 2008:  Chinalco
acquires a c.12% stake in Rio Tinto plc
6 February 2008:  BHP Billiton announced offers for all of the outstanding shares of Rio
Tinto
BHP Billiton Offer for Rio Tinto


Slide 20
BHP Billiton offer for Rio Tinto
Rio Tinto plc Offer:
Rio Tinto plc shareholders will receive 3.4 BHP Billiton shares for every Rio Tinto plc share held
