                              --------------------

     We issued $272,679,000 amount payable at maturity of convertible debentures
due 2023 (the  "Debentures")  on a private  placement basis on March 7, 2003 and
March 18,  2003.  This  prospectus  may be used by  selling  securityholders  in
connection  with resales of the Debentures  and the common shares  issuable upon
the conversion,  redemption,  purchase or payment of the Debentures. Such common
shares are sometimes referred to in this prospectus as the underlying shares.


     The Debentures  are currently  eligible for trading on the PORTAL market of
the National Association of Securities Dealers, Inc. Our common shares currently
trade under the symbol "N" on the New York Stock  Exchange and the Toronto Stock
Exchange.  The last  reported  sale price of our  common  shares on the New York
Stock Exchange on June 4, 2003 was $20.87 per share.
                              --------------------


     INVESTING IN OUR COMMON SHARES OR THE  DEBENTURES  INVOLVES  RISKS.  PLEASE
CAREFULLY  CONSIDER  THE  "RISK  FACTORS"  SECTION  BEGINNING  ON PAGE 4 OF THIS
PROSPECTUS.
                              --------------------

     The  Debentures  and the  underlying  shares may be  offered in  negotiated
transactions or otherwise,  at varying prices determined at the time of the sale
or at negotiated prices. In addition,  the underlying shares may be offered from
time to time  through  ordinary  brokerage  transactions  on the New York  Stock
Exchange.  See "Plan of  Distribution".  This  prospectus  has not been filed in
respect of, and will not qualify,  any  distribution of Debentures or underlying
shares in Ontario or any other  province  or  territory  of Canada.  The selling
securityholders  may be  deemed  to be  "underwriters"  as  defined  in the U.S.
Securities  Act of  1933,  as  amended.  Any  profits  realized  by the  selling
securityholders  may be deemed to be  underwriting  commissions.  If the selling
securityholders use any  broker-dealers,  any commissions paid to broker-dealers
and,  if  broker-dealers   purchase  any  Debentures  or  underlying  shares  as
principals,  any profits  received by such  broker-dealers  on the resale of the
Debentures or underlying shares,  may be deemed to be underwriting  discounts or
commissions under the Securities Act.

     We will not receive any of the proceeds  from the resale of the  Debentures
or the underlying shares by any of the selling securityholders.

reference into, this document.


                   ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

    We are a  corporation  organized  under the laws of Canada and a majority of
our assets are located in, and most of our  directors and officers are residents
of,  Canada.  As a result,  it may be difficult for United  States  investors to
effect  service of process  within the United  States  upon those  directors  or
officers who are not residents of the United States, or to realize in the United
States  upon  judgments  of courts of the United  States  predicated  upon civil
liability of such directors or officers under U.S.  federal  securities laws. We
have been advised by Osler, Hoskin & Harcourt LLP, our Canadian counsel,  that a
judgment of a U.S. court predicated  solely upon civil liability under such laws
would  probably be enforceable in Canada if the U.S. court in which the judgment
was obtained had a basis for jurisdiction in the matter that was recognized by a
Canadian  court for such  purposes.  We have also been advised by such  counsel,
however,  that there is substantial  doubt whether an action could be brought in
Canada in the first  instance on the basis of liability  predicated  solely upon
such laws.

                                  INCO LIMITED

    Inco Limited is one of the world's premier mining and metals  companies.  We
are a leading  producer of nickel,  a hard,  malleable  metal  which,  given its
properties  and  wide  range of  applications,  can be  found  in  thousands  of
products.  We are also an  important  producer  of copper,  precious  metals and
cobalt,  and we produce sulphuric acid and liquid sulphur dioxide as by-products
of our  operations  at Sudbury,  Ontario.  Our  principal  mines and  processing
operations  are located in the Sudbury  area of Ontario,  the  Thompson  area of
Manitoba, and, through our 59 per cent-owned subsidiary, PT International Nickel
Indonesia  Tbk ("PT  Inco"),  on the  island  of  Sulawesi,  Indonesia.  We have
additional  wholly-owned metals refineries at Port Colborne,  Ontario and in the
United Kingdom at Clydach,  Wales and Acton,  England. We also have interests in
nickel  refining  capacity and nickel  salts  production  facilities  located in
Japan, Taiwan, South Korea and the People's Republic of China.

    We currently have two major development projects,  our Goro and Voisey's Bay
projects. We indirectly own an 85 per cent interest in Goro Nickel which holds a
number  of claims  covering  nickel-cobalt  properties  in the  French  Overseas
Territory  of New  Caledonia,  which  we  refer  to as  our  Goro  deposit.  Our
wholly-owned subsidiary,  Voisey's Bay Nickel Company Limited, holds the mineral
licenses  covering the Voisey's Bay deposit and certain other  mineral  licenses
and claims in the Province of Newfoundland and Labrador. We are currently in the
process of  undertaking a review of our Goro project.  See "Risk  Factors--Risks
Associated with, and Importance of, Future Low-Cost Nickel Projects--Uncertainty
of Production and Capital and Other Cost Estimates".

    Our  executive  offices  are located at 145 King  Street  West,  Suite 1500,
Toronto,  Ontario, Canada M5H 4B7. You should refer to our annual report on Form
10-K for the year ended  December  31, 2002 (the "2002  10-K"),  for  additional
information regarding us and our operations throughout the world,  including our
exploration programs and our ore reserves.


                                  RISK FACTORS

    Investment in the Debentures involves certain risks.  Prospective purchasers
of the Debentures should consider  carefully the risk factors set forth below as
well as the other  information  contained and  incorporated by reference in this
prospectus before purchasing the Debentures, including the information contained
in our 2002 10-K.


RISKS RELATING TO OUR BUSINESS

VOLATILITY OF PRICE OF NICKEL AND OTHER PRICES AND THEIR EFFECT ON OUR FINANCIAL
RESULTS

    The price of nickel has represented,  and is currently  expected to continue
to represent, the principal determinant of our profitability.  Accordingly,  our
financial  performance  has been,  and is expected  to  continue to be,  closely
linked to the price of nickel and, to a lesser  extent,  the price of copper and
other primary  metals  produced by us. Since we sell our nickel  products in all
major  geographical  markets,  the prices for primary  nickel and other  primary
metals products realized by us are influenced by both global and regional supply
and  demand  factors  and  by  the  availability  and  prices  of  secondary  or
metal-containing scrap material,  including nickel-containing scrap generated by
the  stainless  steel  industry,  and other  substitute  or competing  commodity
products  for the  primary  nickel and other metal  products  produced by us. In
recent times, the world's nickel and copper markets have been adversely affected
by excess supply conditions.  Based upon available data, we believe that between
mid-1999 and the second half of 2000, global nickel demand exceeded supply,  but
for most, if not all, of 2001, a surplus  condition existed in the global nickel
market.  For 2002,  we estimate  that,  with the  improvement  in global  nickel
demand,  the global nickel market  experienced a modest surplus position.  There
can be no  assurance  that the  excess  supply  situations  which  have  existed
historically in the nickel markets will not occur in the future. Any such excess
supply  condition  would have an adverse effect on the prices realized by us for
our nickel products. Other international economic trends, including an uncertain
global economic  environment,  expectations of inflation and political events in
major nickel-producing and consuming countries can also affect nickel prices and
the prices of other metals  produced by us. These factors are beyond our control
and have resulted,  and are expected to continue to result,  in a high degree of
price  volatility for nickel and other primary metals  produced by us. There can
be no assurance  that the price for nickel or other  metals  produced by us will
not decline  significantly  from current levels.  A return to the relatively low
price of nickel reflected by the London Metal Exchange ("LME") cash nickel price
which prevailed  through most of 1998 and into the first half of 1999 and during
a portion of the second half of 2001 would have a material adverse impact on our
business, results of operations, financial condition and liquidity.


    The price of nickel, as the principal determinant of our profitability,  has
fluctuated  significantly  for many years.  Over the past two years,  there have
been significant  fluctuations in the LME cash nickel price. The LME cash nickel
price on January 2,


                                       4




2001 was $6,995 per tonne  ($3.17 per pound) and fell  during the course of that
year through the end of October 2001,  reaching a low of $4,420 per tonne ($2.00
per pound) on October 31, 2001.  The LME cash nickel price  improved  during the
remainder of the fourth quarter of 2001,  averaging  $5,039 per tonne ($2.29 per
pound) for that  quarter and was $5,680 per tonne  ($2.58 per pound) on December
31,  2001.  The LME cash nickel price opened 2002 at $5,680 per tonne ($2.58 per
pound) and  increased  during the first half of 2002 as the economies of certain
industrialized  countries  began to  recover  from their  relatively  low fourth
quarter  2001  levels,  ending  the first  half of the year at $7,080  per tonne
($3.21 per pound). Prices declined through the third quarter,  reaching a low of
$6,305 per tonne ($2.86 per pound) as concern over the pace of economic recovery
and  uncertainty  about a potential war with Iraq adversely  affected the nickel
markets. Prices increased in the fourth quarter of 2002, and the LME cash nickel
price ended 2002 at $7,100 per tonne ($3.22 per pound).  As of June 4, 2003, the
LME cash nickel  price was $9,280 per tonne  ($4.21 per pound).  We believe that
the  improvement  in the LME cash nickel  price in late 2002 and through June 4,
2003 has been due  principally  to the  recovery in stainless  steel  production
levels and demand for certain other end-use  applications  for nickel in certain
geographic regions. More recently,  the LME cash nickel price has increased,  we
believe,  as a result  of  speculation  that a strike  by our  unionized  hourly
production and  maintenance  workers at our Ontario  operations,  which has shut
down our Ontario  operations,  may adversely affect nickel supply.  However,  we
have not seen any  recovery  in certain  other  important  end-use  markets  for
nickel,  in  particular  the high nickel alloys  industry,  during 2002 and into
2003. Global nickel demand has historically been closely  correlated with global
industrial production.

    Copper is also an important  product for us and, like nickel,  copper prices
have been  volatile for many years.  For 2001,  while the early part of the year
saw some improvement in global copper demand,  copper prices declined during the
course of the year based upon the overall global economic slowdown and increased
copper  inventories.  The COMEX first position cash copper price,  the principal
price upon which our copper  sales are based,  averaged  $1,600 per tonne ($0.73
per pound) in 2001, down 14 per cent from its average of $1,851 per tonne ($0.84
per pound) in 2000. Copper prices for 2002 did not change significantly from the
2001 average,  with the average COMEX first position cash copper price at $1,560
per tonne ($0.72 per pound) for 2002.  On June 4, 2003 the COMEX first  position
cash copper price was $1,715 per tonne ($0.78 per pound).

    Our  development  projects  discussed  under  "Risks  Associated  with,  and
Importance  of,  Future  Low-Cost  Nickel  Projects"  below,  in addition to the
quantities of nickel  projected to be produced by them,  are expected to produce
significant  quantities  of cobalt given the currently  estimated  quantities of
cobalt  in the  mineral  deposits  to be mined as part of these  projects.  With
significant  increases in the global supply of cobalt and changes in demand, the
price of  cobalt  has  fluctuated  significantly  over the past  several  years,
reaching a high of $70.30 per  kilogram  ($31.90 per pound) in January  1996 and
declining significantly from that peak to an average price, based upon the Metal
Bulletin 99.8 per cent average cobalt  reference  price,  of $15.66 per kilogram
($7.10 per pound) for 2002 and  was  $22.22 per  kilogram  ($10.08 per pound) on
June  4,  2003.  The  financial  analyses  undertaken  by us in  support  of the
substantial  investment to be made with respect to these projects has been based
upon a long-term  price of cobalt of $15.40 per kilogram  ($7.00 per pound).  If
realized  cobalt prices,  as well as realized  prices for the other metals to be
produced by these projects, were to be below the long-term prices assumed by us,
the expected  financial  returns from, and expected cash and other unit costs of
production for, these projects would be adversely affected.


    For  information  concerning the sensitivity of our results of operations to
certain  changes  in the price of nickel  and other  metals  refer to "Risks and
Uncertainties--Sensitivities"   in  the  Management's  Discussion  and  Analysis
included as an exhibit to our 2002 10-K.

RISKS ASSOCIATED WITH, AND IMPORTANCE OF, FUTURE LOW-COST NICKEL PROJECTS

    As part of our strategy to be the world's  lowest-cost  and most  profitable
nickel  producer,  we have continued our efforts to develop new low-cost sources
of nickel.  Following the  completion of the PT Inco  expansion  project in late
1999, we have focused on potential  future  projects to  commercialize  our Goro
nickel-cobalt deposit and Voisey's Bay nickel-copper-cobalt deposit. A number of
risks and  uncertainties  are associated with the development of these projected
low-cost sources of nickel and other metals,  including  political,  regulatory,
design,  construction,  labor,  operating,  technical and  technological  risks,
uncertainties  relating to capital and other costs and  financing  risks and, in
the case of Goro, those risks related to the possible transition to independence
in the future of the French overseas territorial community of New Caledonia.

    In addition  to the risks and  uncertainties  referred  to above,  there are
certain  issues that must be resolved to enable the  commercial  development  of
each of these  deposits  to  proceed.  For the Goro  deposit,  we still  need to
receive  the  necessary  environmental  and  operating  permits,   complete  our
comprehensive review of the schedule, capital costs, scope and other key aspects
of this project and develop an  acceptable  updated  capital  cost  estimate (as
discussed under "Uncertainty of Production and Capital and Other Cost Estimates"
below) and, as  discussed  below,  complete the  required  financing,  including
bringing in a partner for the project,  on acceptable  terms. In the case of our
Voisey's Bay deposit, the principal issues that would have to be resolved before
commercial  development can begin include issuance of the necessary construction
and  operating  permits,  meeting the  conditions  to be met with respect to the
overall  effectiveness  of the definitive  agreements on the  development of the
Voisey's  Bay  deposit  reached  in  October  2002  between  the  Government  of
Newfoundland and Labrador and us and

                                       5



the availability of financing required for development on acceptable terms.

    In  connection  with raising the  significant  financing  which we currently
believe will be required for the commercial development of the Goro and Voisey's
Bay deposits,  we currently  expect that, in order to meet such financing needs,
we will be required to borrow  additional  funds  and/or issue  additional  debt
and/or equity or arrange other forms of financing and/or enter into strategic or
other  arrangements.  Our  current  plans for  development  of Goro  contemplate
finalization of at least approximately $350 million in tax-advantaged  financing
under an  existing  French  legislative  program.  Our  plans  also  contemplate
finalization of the terms and conditions under which a Japanese consortium to be
led by Sumitomo  Metal Mining Co., Ltd.  would acquire a 25 per cent interest in
Goro and assume,  subject to certain limitations,  the obligation to fund 25 per
cent of the capital  costs of the Goro project.  There can be no assurance  that
these arrangements will be finalized or that we will be able to raise additional
required funds on acceptable  terms when financing is needed for either project.
As  discussed  under  "Uncertainty  of  Production  and  Capital  and Other Cost
Estimates" below, while we have certain potential new mine development  projects
at existing operations in Canada, as well as additional  resources that could be
developed in Indonesia,  in addition to the Voisey's Bay and Goro  projects,  if
sufficient  new low-cost  sources of nickel are not  developed by us on a timely
basis, our overall nickel production,  particularly at our Manitoba  operations,
could  decline  by  2004,  and  our  unit  cost  of  production  could  increase
significantly  with any material  decline in mine  production  from the Canadian
operations  if  such  operations  were  not  significantly  restructured.  These
developments  could  materially  adversely  affect  our  business,   results  of
operations, financial condition and liquidity.

CONSTRUCTION RISKS AND TECHNOLOGICAL RISKS

    The  mine,  processing  plant  and  related   infrastructure   required  for
development of the Goro and Voisey's Bay deposits have not yet been  constructed
and no commercial  mining has commenced.  While certain  necessary  construction
permits  have  been  obtained  in  respect  of the  Goro  deposit  and  detailed
exploration  and related  studies with respect to the Goro deposit and a portion
of the Voisey's Bay deposit have been completed based on (1) significant surface
exploratory   drilling,   (2)  extensive   investigations   of  certain  of  the
mineralization  delineated to date,  (3)  construction  and mine plans,  and (4)
production  and cost  estimates,  we are not  currently in a position to predict
when all of the required  approvals  would be in place for us to develop  either
project  and,  in the  case of the  Goro  project,  when  construction  would be
restarted  given the status of the  comprehensive  review,  as  discussed  under
"Uncertainty  of  Production  and Capital and Other Cost  Estimates",  currently
being  undertaken,   and,  in  the  case  of  the  Voisey's  Bay  deposit,  when
construction  will be able to  commence.  Depending  on the  severity  of winter
conditions and other factors applicable to the Voisey's Bay deposit, a period of
approximately  36 months  from site  mobilization  will be  required to complete
construction  of the  initial  phase,  the  mine,  mill and  related  facilities
necessary  for the  commercial  development  of such deposit after all necessary
approvals and permits have been secured.

    Unforeseen  conditions or developments  could arise during the  construction
period for either  project  which  could  delay or  prevent  completion,  and/or
substantially  increase the cost of construction of the necessary facilities and
infrastructure  to develop the Goro and the Voisey's Bay  deposits.  Such events
may include,  without  limitation,  shortages of equipment,  materials or labor,
delays in delivery of  equipment  or  materials,  labor  disruptions,  political
events, local or political opposition, civil disturbances,  litigation,  adverse
weather  conditions,  unanticipated  increases  in costs,  natural  or  man-made
disasters,  accidents and unforeseen  engineering,  technical and technological,
design,  environmental,  geological  or  geotechnical  problems.  Any  delay  in
construction  would delay the  production of nickel and other  products from the
Goro and/or the Voisey's Bay deposits,  and the expected  significant  source of
revenue for us that  production  from these deposits would  represent.  Any such
delay  could  also  materially   adversely  impact  our  business,   results  of
operations, financial condition and liquidity.

    Our Goro project will involve the  application  of new  processing and other
technologies and, depending upon the results of the  hydrometallurgical  process
research  and  development  program  we plan to  conduct  for our  Voisey's  Bay
project,  that project could also utilize new processing and other  technologies
to produce one or more  refined or  finished  nickel  products.  There can be no
assurance that these technologies will be successfully  developed and applied on
a commercial  basis or that the costs associated with and/or the timing of their
implementation  will not have a  material  adverse  effect on the  timing of the
start-up of commercial production, the capital and/or operating costs for either
or both  projects and on other  factors  impacting  the  profitability  of these
projects.  These  developments  could materially  adversely impact our business,
results of operations, financial condition and liquidity.

UNCERTAINTY OF PRODUCTION AND CAPITAL AND OTHER COST ESTIMATES

    In the case of our Goro project,  in September 2002, at the time the project
was experiencing certain labor disruptions,  we initiated a review of the status
of certain key  aspects of the  project,  including  the  necessary  permitting,
capital   cost   estimate,   schedule   and   organization.    Work   over   the
September--November  2002  period  on  certain  critical  parts of the  project,
including  engineering,  continued  during this initial  review.  On December 5,
2002, we announced  that we would be undertaking a  comprehensive  review of the
Goro  project.  The  objective  of the  comprehensive  review is to  assess  all
information  on our Goro

                                       6



project,  including the various cost  estimates and trends,  and determine  what
changes in the capital cost estimate and the project can be made to maintain the
project's  economic  feasibility.  The review of the capital cost  estimate will
cover what downward  adjustments  can be made in such estimate  through scope or
design changes,  modifications  to construction  and related plans and civil and
other contractual  arrangements,  and alternative project execution  strategies.
Since that  announcement,  we have been  evaluating what onsite and offsite work
should be  curtailed  or stopped  and what work should be  continued  while this
review is  ongoing.  The  comprehensive  review was  commenced  in  response  to
information we received from the principal firms providing project  engineering,
procurement  and  construction  management  services  that, if confirmed,  would
indicate an  increase in the capital  cost for the project in the range of 30 to
45 per cent above the then current capital cost estimate of $1,450 million. As a
result of the temporary  suspension of certain development  activities and other
actions  which had been taken by year-end  2002 during this review  process,  we
recorded a pre-tax  charge of $25  million in the fourth  quarter of 2002.  This
charge  was  comprised  of  pre-tax  expenses  of $62  million  relating  to the
cancellation or termination of certain outstanding contractual  obligations,  to
accrue  for  demobilization  costs and to reduce the  carrying  value of certain
assets  relating  to the  project,  partially  offset by  currency  gains of $37
million from the early settlement of certain forward currency contracts that had
been entered into for hedging purposes.  Based upon this ongoing evaluation,  we
have also been reviewing  various  contractual and other  arrangements  covering
construction  and other  work  relating  to the Goro  project  and  implementing
certain   actions  to  suspend  or  terminate   certain  of  those   contractual
arrangements.


    As of March 31, 2003,  we had spent  approximately  $475 million on the Goro
project since July 1, 2001 when this project was formally launched.  This amount
excludes a current estimate of approximately  $87 million that  would still have
to be spent for  equipment,  services  and  other  requirements  under  existing
contracts  and commitments,  and accruals as of March 31, 2003  of approximately
$70 million  relating to such  requirements,  most of which  is expected to have
value for the project.

    Since the Goro project  review  process is still in its  preliminary  stages
given its  planned  scope,  we do not  currently  expect to be in a position  to
report on the results of this review, including an updated capital cost estimate
for the project and the additional  effect,  if any, that this review could have
on our financial results,  until at least early in the third quarter of 2003. We
have been working with various parties to assist us in the review process. While
the key objective of this comprehensive  review is to implement such actions and
steps,  if  required,  to have a project  that will meet an  acceptable  rate of
return on the investment to be made in this project,  if, upon completion of the
review,  we were to conclude that the Goro project could not be  restructured to
meet our rate of return on  investment  requirements,  we would likely write off
all or a  substantial  portion of the carrying  value of the Goro project and we
would also lose the expected  future  production  from Goro. Such a result would
have a material adverse effect on our business, results of operations, financial
condition and liquidity.

    During 2002, as mine production at our Manitoba operations transitioned from
the Thompson mine to the lower grade Birchtree  mine, we experienced  lower mine
production.  As this transition  moves forward,  we expect to see declining mine
production  in  Manitoba  in 2003 and in future  years.  We have  recently  been
relying  upon,  and will  continue to rely upon,  on an  increasing  basis,  the
availability of purchased intermediates to maintain Manitoba's nickel production
at around  the 45,000  tonne  annual  level.  While we  anticipate  that we will
continue to be able to purchase  intermediates to maintain Manitoba's production
levels at such  levels for the next few years,  until the  Voisey's  Bay project
produces intermediates in the form of concentrates for further processing at the
Manitoba and Ontario  operations,  if suppliers of the  purchased  intermediates
were to experience  production problems or other disruptions,  this could have a
material  adverse  effect  on  our  nickel  production,   business,  results  of
operations,  financial condition and liquidity.  While we have certain potential
new  mine  development  projects  at  our  existing  operations  in  Canada,  if
sufficient  new  low-cost  sources of nickel such as our  Voisey's  Bay and Goro
projects are not developed on a timely  basis,  our overall  nickel  production,
particularly  at our Manitoba  operations,  could decline by 2004,  and our unit
cost of production  could increase  significantly  with any material  decline in
mine  production  from  our  Canadian  operations  if such  operations  were not
significantly restructured. These developments could materially adversely impact
our business, results of operations, financial condition and liquidity.


    The level of production and capital and operating cost estimates relating to
the Goro project, the Voisey's Bay project and other projects of ours, which are
used in  establishing  ore reserve  estimates and for  determining and obtaining
financing  and  other  purposes,  are  based  on  certain  assumptions  and  are
inherently  subject  to  significant  uncertainties.  In the  case  of our  Goro
project,  as  discussed  above,  the review by us could result in a capital cost
estimate substantially higher than the 15 per cent increase in the estimate that
we had indicated in the third quarter of 2002 could occur given the then current
state of project procurement and engineering.

    We announced  on March 20, 2003 (i) the results of our bankable  feasibility
study for the mine for the Ovoid and adjacent surface deposits, concentrator and
related  facilities  representing  part of the initial phase of the Voisey's Bay
project and (ii) that we plan to proceed with this initial phase. Based upon the
results  of the  study,  the  estimated  total  capital  cost  for the  mine and
6,000-tonne per-day  concentrator and related facilities  representing the mine,
concentrator and related  facilities and infrastructure in the Voisey's Bay area
(the  "Mine/Concentrator  Project") will be $582 million,  including $35 million
spent since July 2002 on  infrastructure  and  related  work.  The $582  million
amount  represents  an  increase  of $77  million  or about 15

                                       7



per cent  over the  prefeasibility  study  estimates  for the  Mine/Concentrator
Project. This estimate includes a $54 million contingency.  The initial phase of
the Voisey's Bay project  will also involve a research and  development  program
covering hydrometallurgical processing technologies (the "Hydromet R&D Program")
for the treatment of the Voisey's Bay nickel and cobalt-containing  concentrates
to  be  produced  into  finished  nickel  and  cobalt  product,   including  the
demonstration  plant to be constructed in Argentia,  Newfoundland.  The Hydromet
R&D Program is expected to cost  approximately $134 million or about 14 per cent
above  the   initial   estimate   for  this   program.   In   addition   to  the
Mine/Concentrator  Project and the Hydromet R&D Program,  the initial phase will
include handling facilities to be constructed at our Canadian operations for the
nickel and  cobalt-containing  concentrates to be processed over the 2006 - 2011
period once the  Mine/Concentrator  Project and the  demonstration  plant are in
operation, at an estimated cost of $47 million, and an exploration program at an
estimated  cost of $13 million.  The total  capital  cost  estimate for all four
parts of the initial phase of the Voisey's Bay project is $776 million, or about
14 per cent  above the  prefeasibility  study  estimates  of $680  million.  The
engineering  firm retained to complete the study has indicated  that it believes
that the capital cost estimate is within a range of plus 15% and minus 5% of the
$547 million figure still to be spent for the Mine/Concentrator Project.

    It is very likely that actual  results for these  projects  will differ from
our current estimates and assumptions, and these differences may be material. In
addition,  experience  from actual mining or processing  operations may identify
new or  unexpected  conditions  which  could  reduce  production  below,  and/or
increase capital and/or operating costs above, our current estimates.  If actual
results are less favorable than we currently estimate, our business,  results of
operations,  financial  condition  and liquidity  could be materially  adversely
impacted.

RISKS ASSOCIATED WITH PT INCO

    Our  investment  in PT Inco at book value as of December  31, 2002  totalled
$364 million.  Approximately 30 per cent of our 2003 planned total production of
primary nickel,  including  intermediate  product, is currently expected to come
from  PT  Inco.  In  1999,  to  meet  PT  Inco's  cash  shortfalls  attributable
principally  to the  increase  in the  capital  cost  of the  new  hydroelectric
facilities  which were part of PT Inco's expansion  project,  the relatively low
nickel prices,  and  constraints on PT Inco's  production  attributable  to then
reduced  hydroelectric  power generation  caused by below average  rainfall,  we
advanced $88 million in total to PT Inco. These advances have since been repaid.
PT Inco may experience cash shortfalls in the future, particularly if there were
to be a significant  decline in primary nickel demand and nickel prices.  In the
event of such a cash shortfall, we may again conclude that it would be necessary
to advance cash to PT Inco in order to meet PT Inco's cash needs.

    The uncertain political situation in Indonesia, primarily as a result of the
ongoing  economic and political  problems  facing that country,  could adversely
affect PT Inco's ability to operate. While there has been no indication that the
Government  of the  Republic of  Indonesia  is  considering  currency  controls,
nationalization  of certain  properties or facilities or other similar  actions,
regional and local governmental  authorities have sought to take greater control
of the development of their resources and these or other political developments,
including,  but not  limited to, the  possibility  of  disruptions  in PT Inco's
operations  arising  out of the  actions of  non-governmental  organizations  or
community  activist  groups,  could have a material adverse effect on PT Inco's,
and therefore our, nickel production, business, results of operations, financial
condition and liquidity.

ENVIRONMENTAL RISKS

    Environmental  legislation  affects  nearly all  aspects  of our  operations
worldwide.  These laws apply to us along with other  companies in the mining and
metals  industry.  This type of  legislation  requires  us to  obtain  operating
licenses,  permits and other  approvals  and imposes  standards  and controls on
activities relating to mining, exploration, development, production, closure and
the refining,  distribution  and marketing of nickel and other metals  products.
Environmental  assessments are required  before  initiating most new projects or
undertaking  significant changes to existing operations.  In addition to current
requirements, we expect that additional environmental regulations will likely be
implemented  to protect the  environment  and quality of life,  given  issues of
sustainable  development and other similar  requirements  which governmental and
supragovernmental organizations and other bodies have been pursuing. Some of the
issues currently under review by environmental  regulatory  agencies include (1)
further reducing or stabilizing  various  emissions,  including sulphur dioxide,
metal and greenhouse gas emissions,  (2) mine reclamation and  restoration,  and
(3) water, air and soil quality and waste treatment and disposal.

    Although  the  ultimate  amount  to be  incurred  is  uncertain,  the  total
liability  for  future  removal  and site  restoration  costs in  respect of our
worldwide operations, to be incurred primarily after cessation of operations, is
estimated to be  approximately  $415 million at December 31, 2002,  up from $315
million at December 31, 2001. The increase was primarily due to the inclusion of
new estimates for certain sites.  In recognition  of this future  liability,  we
have recorded annually commencing in 1995 an accounting provision of $10 million
for future  removal  and site

                                       8



restoration  costs,  which is included in cost of sales and operating  expenses.
This amount is based upon the estimated  remaining  lives of our  applicable ore
reserves  and  facilities  and is in addition to ongoing  operating  and capital
expenditures.  The estimate of the total  liability for future  removal and site
restoration  costs has been developed from  independent  environmental  studies,
which  include an  evaluation  of,  among  other  factors,  currently  available
information  with  respect  to  closure  plans  and  closure  alternatives,  the
anticipated  method  and  extent of site  restoration  using  current  costs and
existing  technology,   and  compliance  required  by  presently  enacted  laws,
regulations  and existing  industry  standards.  The total  liability for future
removal and site restoration costs represents estimated expenditures  associated
with closure,  progressive rehabilitation and post-closure care and maintenance.
Potential  recoveries  of funds from the future sale of assets upon the ultimate
closure of  operations  have not been  reflected  in the  estimate  of the total
liability or related annual provision.  Future changes, if any, to the estimated
total  liability,  as a result of amended  requirements,  laws,  regulations and
operating  assumptions may be significant and would be recognized  prospectively
as a change in accounting  estimate,  when  applicable.  Environmental  laws and
regulations are continually evolving in all areas in which we operate.

    Changes made in 2000 to mining  regulations  in the Province of Ontario will
require us to provide letters of credit or other forms of financial  security to
fund our future  reclamation and restoration costs, which are not expected to be
incurred for many years, if we were to no longer meet certain minimum investment
grade  credit  ratings for our  outstanding  publicly  traded  debt  securities.
Although our debt securities are currently  rated  investment  grade,  they were
rated below  investment grade in recent times and there can be no assurance that
this  situation  will not  reoccur.  If we are not able to maintain  the minimum
investment  grade  credit  ratings,  it is currently  estimated  that letters of
credit  or other  forms of  financial  security  associated  with the  currently
estimated costs of the eventual future closure of our mines and other facilities
in Ontario would have to cover approximately $310 million in such closure costs.
Due to the recent  closure of three mines in Ontario in 2002,  we were  required
under  such  mining  regulations  to provide  surety  bonds in the amount of $17
million as of December 31, 2002 to secure  closure  costs.  In addition,  we are
subject to certain  Indonesian  regulations which require us to provide security
for the  reclamation  of land  areas  that have been  mined.  In the case of our
Manitoba  operations we expect that, based upon recently enacted  regulations in
the Province of Manitoba,  we will be required to provide some form of financial
security for our future  reclamation  and  restoration  costs in that  Province.
However, it is not currently expected that these costs and related security with
respect to our Manitoba  operations  (beyond what has been  included in the $415
million estimate referred to above) and for our Indonesian operations will be of
a material amount.  These potential costs might not be incurred until many years
in the  future.  If these  requirements  for letters of credit or other forms of
financial security had to be satisfied, they could have an adverse effect on the
amounts available for borrowing under our bank credit facilities.

    In  February  2002,  the  Ontario  government  issued a control  order  that
requires us to reduce  sulphur  dioxide  emissions by 34 per cent at our Ontario
smelting  operations  by the end of  2006.  We are  implementing  a $76  million
investment in fluid bed roaster off-gas scrubbing  technology intended to reduce
sulfur dioxide emissions to the new levels mandated by this new control order by
the end of 2006. As part of the control  order,  we will also be required to (1)
reduce ground level concentrations of sulfur dioxide, (2) continue research into
the technology and economics of further  reductions in sulphur dioxide emissions
and (3) report  annually to the  Ontario  Ministry  of the  Environment  and the
public on the progress of this research  program.  The control order calls for a
final report on achieving the additional  reductions to be submitted by December
31, 2010. We do not currently  expect that  compliance  with the annual  sulphur
dioxide   emission   levels  from  our  smelter   operations   or  ground  level
concentrations  levels  as  set  forth  in  the  control  order  will  have  any
significant  effect on our costs,  operating  procedures or annual production of
nickel and other  primary  metals from our Ontario  operations.  The Province of
Ontario  recently  issued a  discussion  paper  covering  proposals  for further
reductions  in sulfur  dioxide  emissions by  non-ferrous  smelting  operations,
including  our  operations,  and the federal  government  of Canada has recently
designated  for  further  regulation  certain  sulfur  dioxide  and  particulate
emissions  from  copper-smelting  operations  such as those we have in  Ontario.
While  we are  not  able to  determine  the  effect,  if any,  of  these  recent
developments  and significant  future changes in regulatory  emission limits and
other  environmental  laws and regulations that may be enacted in the future due
to the  uncertainty  surrounding  the timing and ultimate form that such changes
may take, any such changes could have a material adverse effect on our business,
results of operations, financial condition and liquidity.

    Canada  signed  and  ratified  the  Kyoto  Protocol  to the  United  Nations
Framework  Convention on Climate Change ("Kyoto Protocol") in December 2002. The
Kyoto Protocol calls for  significant  reductions in the emissions of greenhouse
gases,  such as carbon dioxide,  and nationwide  ceilings on such emissions.  In
November  2002,  the federal  government  of Canada  released an  initiative  to
address  certain  causes of climate  changes.  The specific  requirement of this
initiative is also to limit the discharge of carbon dioxide and other greenhouse
gases.  Neither of these  initiatives has as yet established what the allocation
of restrictions  among various  sources of greenhouse  gases would be. While the
precise  impact on our  Canadian  operations  and the  operations  of others who
provide energy or other products or services to us is uncertain at this time, we
anticipate  that  compliance  with these  initiatives  could have a  significant
adverse effect on our results of operations and costs.

    In  2002,  the  Danish  Environmental  Protection  Agency,  as  part  of the
authority granted to it under certain environmental  regulations of the European
Union  Commission,  published draft risk assessment  reports,  including certain
conclusions  concerning  potential  human health hazards  associated with nickel
metal and certain soluble nickel  compounds,  including nickel sulphate,  nickel
chloride and nickel  nitrate.  This Agency  determined,  based on certain animal
studies,  that soluble nickel is a


                                       9



reproductive toxin and has proposed certain product labelling  requirements as a
result of this  determination.  It has also assessed certain other environmental
issues.   In  addition,   based  upon  these  draft   reports  and  taking  into
consideration  certain studies,  this Agency has proposed that soluble nickel be
classified under its hazard  classification  system as a known human carcinogen.
Before any such  proposed  classification  could come into  effect,  a number of
regulatory and administrative steps would have to be completed. If this proposed
classification were to come into effect as currently  proposed,  it could result
in use restrictions and other  requirements  which could have a material adverse
impact on certain producers and end users of the forms of nickel covered by such
classification and on our business,  results of operations,  financial condition
and liquidity.  The European Union  Commission also in 2002 proposed a directive
on air pollution  which includes  target limit values for nickel since nickel is
considered by this Commission to be a possible  carcinogenic  pollutant.  Member
states of the  European  Union will have until 2010 to achieve the target  limit
values,  after which more stringent binding limit values may be considered.  The
technical and  socio-economic  feasibility  of meeting such limits are currently
being  considered by the European  Union  Commission and those  industries  that
would be affected, including nickel producers.

    Further changes in environmental  laws, the restrictions on our discharge of
greenhouse  gases as a result  of  Canada's  program  to  comply  with the Kyoto
Protocol  and similar  developments  that may be  imposed,  new  information  on
existing environmental  conditions and other events, including legal proceedings
brought based upon such conditions or an inability to obtain necessary  permits,
could require increased  financial  reserves or compliance or other expenditures
or  otherwise  have a  material  adverse  effect  on our  business,  results  of
operation, financial condition and liquidity.

    Other changes in  environmental  legislation  could have a material  adverse
effect on  product  demand,  product  quality  and  methods  of  production  and
distribution.  The  complexity  and breadth of these  issues  make it  extremely
difficult  to  predict  their  future  impact  on  us.  We  anticipate   capital
expenditures  and operating  expenses will increase in the future as a result of
the implementation of new and increasingly stringent environmental  regulations.
Compliance with environmental  legislation can require significant  expenditures
and  failure  to  comply  with  environmental  legislation  may  result  in  the
imposition of fines and penalties, liability for clean up costs, damages and the
loss of important permits.

    There can be no assurance  that we will at all times be in  compliance  with
all  environmental  regulations or that steps to bring us into compliance  would
not materially  adversely affect our business,  results of operation,  financial
condition or liquidity.  We may also be subject to claims from persons  alleging
that they have  suffered  significant  damages as a result of the  environmental
impact of our  operations,  including  operations  that have ceased to exist for
many years.

COMPETITION

    The nickel  industry is highly  competitive  in all  aspects of  operations,
including the  exploration  for, and the  development of, new sources of supply,
the acquisition of deposits,  and the processing,  distribution and marketing of
nickel  products.  The level of  production  and  export of  primary  nickel and
secondary or  nickel-containing  scrap  material from the Russian  Federation as
well as other  sources of such scrap,  together with the  continuing  relatively
limited level of domestic  consumption of nickel in the Russian Federation since
the break-up of the former Soviet Union, has had, and is expected to continue to
have, a significant impact on the nickel industry's supply-demand balance.

    During  1999,  three new  nickel  projects  in  Australia  began  commercial
production  at costs of  production  which the  sponsors  of such  projects  had
estimated  to  be  very  favorable  relative  to  other  industry  participants,
including  us.  While these  projects  still have not operated at close to their
aggregate  indicated  production  capacity,  which had been  estimated  by their
sponsors to be approximately  65,000 tonnes annually in total,  increases in the
supply of nickel  resulting from those  projects,  and from other new sources of
nickel,  if developed,  could create downward  pressure on prices realized by us
for our primary nickel products.

    While we expect  that the demand for nickel  will  continue to grow over the
longer  term,  increases  in supply in excess of increases in demand could cause
nickel  prices to remain at  current  levels or to  decrease  further.  Any such
situation could materially adversely affect our business, results of operations,
financial  condition and  liquidity.  See  "--Volatility  of Price of Nickel and
Other Prices and their Effect on Our Financial  Results"  above. As we expect to
become a  significant  producer of cobalt once our  development  projects  begin
commercial  production,  our  results  will also be  affected  by the  currently
projected highly competitive market for cobalt.

GOVERNMENTAL REGULATIONS

    In addition to environmental  regulations  referred to above, the mining and
metals  industry in Canada  operates  under  federal,  provincial  and municipal
legislation,  regulation and intervention by governments in such matters as land
tenure, limitations on areas in which mining can be conducted, production rates,
income  and other  taxes and the  export of ore and other  products,  as well as
other matters.  Our operations in Indonesia,  the United Kingdom,  New Caledonia
and other countries outside Canada are also subject to various environmental and
other  applicable laws and regulations and governmental


                                       10



interventions, some of which are similar to those in Canada and all of which are
subject to change.  The mining and metals industry is also subject to regulation
and  intervention by governments in such matters as control over the development
and  abandonment  of mine  sites  (including  restrictions  on  production)  and
possible  expropriation  or cancellation of contract and mineral rights.  Before
proceeding  with major  projects,  including  significant  changes  to  existing
operations, we must obtain regulatory approvals. The regulatory approval process
can involve  stakeholder  consultation,  environmental  impact  assessments  and
public hearings,  among other things. In addition,  regulatory  approvals may be
subject to conditions,  including the  obligation to post security  deposits and
other financial commitments.  Failure to obtain regulatory approvals, or failure
to obtain them on a timely  basis,  could  result in delays and  abandonment  or
restructuring  of projects and increased  costs,  all of which could  negatively
affect our future earnings and cash flow. In addition,  such  regulations may be
changed from time to time in response to economic or political  conditions,  and
the   implementation   of  new  regulations  or  the  modification  of  existing
regulations  affecting the mining and metals  industry  could increase our costs
and have a material adverse impact on business, results of operations, financial
condition and liquidity.

    There can be no assurance that we will be in compliance  with all applicable
statutes or regulations  at all times or that steps to bring us into  compliance
would not  materially  adversely  impact our  business,  results of  operations,
liquidity or financial condition. See "--Environmental Risks" above.

CAPITAL REQUIREMENTS AND OPERATING RISKS


    Each of our  two  current  principal  primary  metals  business  units,  the
Canadian and U.K. operations and our 59 per cent owned Indonesian subsidiary, PT
Inco,  has required,  and is expected to continue to require,  certain levels of
investment to sustain its current levels of  production.  For 2003, we currently
forecast capital  expenditures  totalling  approximately $680 million,  covering
sustaining capital projects for these units as well as planned  expenditures for
our Goro and Voisey's Bay projects and other  development  projects.  This total
amount  assumes a level of  capital  expenditures  for our Goro  project of $260
million,  which may be higher or lower  depending upon the results of the review
referred  to under  "--Uncertainty  of  Production  and  Capital  and Other Cost
Estimates" above and other  developments,  and $185 million for our Voisey's Bay
project,  which is based upon upon the results of the bankable feasibility study
referred  to above  and  other  developments.  We  anticipate  very  substantial
continuing  capital  expenditures  in 2004 and  subsequent  years for sustaining
capital projects and for our development projects. The expected capital costs of
each of our two major  development  projects are under review and may ultimately
be much  higher  than  what  we  currently  anticipate.  To  meet  such  capital
expenditure  requirements,  we must generate  sufficient  positive internal cash
flow and/or utilize available financing sources.


    In addition, our mining operations and processing and related infrastructure
facilities  are subject to risks  normally  encountered in the mining and metals
industry.  Such  risks  include,  without  limitation,   environmental  hazards,
industrial accidents, labor disputes, changes in laws, technical difficulties or
failures,  late  delivery  of  supplies  or  equipment,  unusual  or  unexpected
geological  formations or pressures,  cave-ins,  pit-wall failures,  rock falls,
unanticipated ground, grade or water conditions,  flooding, periodic or extended
interruptions  due to the  unavailability of materials and force majeure events.
Such risks could result in damage to, or destruction  of, mineral  properties or
producing facilities, personal injury, environmental damage, delays in mining or
processing,  losses and possible  legal  liability.  Any  prolonged  downtime or
shutdowns at our mining or  processing  operations  could  materially  adversely
affect our business, results of operations, financial condition and liquidity.

    For example,  we recently  experienced  certain seismic conditions at two of
our  mines  at our  Ontario  operations  which  required  us to  curtail  mining
activities  while these  conditions  were  evaluated.  These  conditions did not
result in any significant production disruptions but could reoccur in the future
and  could  adversely  affect  our  production.   In  addition,  our  Indonesian
subsidiary recently experienced an unexpected  maintenance  requirement covering
one of its two hydroelectric  generating facilities which will require a limited
shutdown  of the  facility  to repair the  facility's  two  turbines.  We do not
currently  expect  that  this  shutdown  will  affect  PT  Inco's  2003  planned
production, although there can be no assurances in this regard.

    The wholesale  electricity markets in Ontario were deregulated for a portion
of 2002 and as a result we experienced  fluctuations  in some of our electricity
costs at our Ontario operations. Depending upon future changes in the regulatory
environment for these markets,  we could experience future  fluctuations in such
costs. We have from time to time experienced  adverse  production and production
cost  trends at our  operations  in Canada and  elsewhere  and could  experience
similar adverse trends in the future.

LABOR RELATIONS


    Our collective  agreement with unionized  hourly  production and maintenance
workers at our  Ontario  operations  expired on May 31,  2003.  On June 1, 2003,
these workers went on strike,  effectively shutting down our Ontario operations.
The Company at this time can not predict  when its  Ontario  operations  will be
back in production.  Such a disruption will adversely  affect our

                                       11




operations  and could  materially  adversely  impact  our  business,  results of
operations, financial condition and liquidity.

    A three-year  collective  agreement with our unionized office,  clerical and
technical  employees at our Ontario operations remains in effect until March 31,
2004.  On September 15, 2002, a new  three-year  collective  agreement  with our
unionized workers at our Manitoba operations was successfully negotiated. Our PT
Inco subsidiary entered into a new two-year  collective labor agreement with its
union in January  2003.  While  there were no  significant  problems in reaching
agreement on this new agreement  with PT Inco's labor force,  with the increased
potential for actions of non-government organizations and other activist groups,
as part of the current uncertain economic and political  situation in Indonesia,
and the general  increase in labor  activism  in that  country,  there can be no
assurance  that such  activism will not  adversely  affect PT Inco's  ability to
successfully  operate.  Any  disruption  in PT Inco's  operations as a result of
labor  issues or other  issues may  adversely  affect its  operations  and could
materially  adversely  impact our  business,  results of  operations,  financial
condition and liquidity. At Goro, we currently have two unions representing some
of our employees. In early September 2002, Goro experienced labor disruptions by
personnel  associated with certain  project  construction  subcontractors  which
resulted in the curtailment of certain activities at the project's site. Through
an employers' association, of which we are the controlling member, we negotiated
a collective  agreement effective September 2002 covering the construction phase
of the Voisey's Bay project.

    There  can  be  no  assurance  that  new  collective   agreements   will  be
successfully  negotiated when current  collective  agreements expire and without
work  interruptions.  We could also be adversely  affected by labor  disruptions
involving  third  parties  who may  provide  us with  goods or  services  at our
operations in Canada and elsewhere.  For example,  as discussed  above, our Goro
project has  experienced  labor  disruptions  by employees  of our  construction
contractors. Any lengthy work interruptions at our Goro or Voisey's Bay projects
could  materially  adversely  affect  the timing of  completion  and the cost of
either  project,  as well as our  business,  results  of  operations,  financial
condition and liquidity.


UNCERTAINTY OF RESERVE ESTIMATES

    Our reported ore reserves are  estimated  quantities  of proven and probable
ore  that  under  present  and   anticipated   conditions  can  be  legally  and
economically mined and processed by the extraction of their mineral content.  We
determine the amount of our ore reserves in accordance with the  requirements of
the  applicable  securities  regulatory  authorities  and  established  industry
practices,  based upon a number of assumptions,  including  long-term prices for
nickel,  copper and cobalt.  In some cases, we assume  long-term prices that are
above current and recent  prices.  Changes in these  assumptions,  including any
reduction in the assumed metals prices,  could  materially  adversely affect the
calculation  of the  quantities  of proven and  probable  ore  reserves  and any
significant  reduction in such reserves  could  adversely  affect our production
levels and, accordingly, our financial results. The volume and grade of reserves
actually  recovered and rates of production from our present ore reserves may be
less than what is indicated by geological measurements of the reserves. Further,
market  price  fluctuations  in nickel,  other metals and  exchange  rates,  and
changes in  operating  and capital  costs may in the future  render  certain ore
reserves uneconomic to mine. See also "--Volatility of Price of Nickel and Other
Prices  and  their  Effect  on Our  Financial  Results"  and  "--Uncertainty  of
Production and Capital and Other Cost Estimates".

    No assurance can be given that the indicated amount of ore will be recovered
or that it will  be  recovered  at the  rates  anticipated  by us.  Our  reserve
estimates are based on limited sampling and, consequently, are uncertain because
the samples may not be representative  of the entire orebody.  As more knowledge
and understanding of the ore body is obtained,  the reserve estimates may change
significantly, either positively or negatively.

RISKS RELATING TO BANK FACILITIES


    To provide liquidity for our operations,  we maintain  committed bank credit
facilities currently aggregating $630 million, none of which was drawn as of the
date hereof.  Covenants  contained in these bank credit facilities require us to
maintain a consolidated  indebtedness to tangible net worth ratio, as defined in
such  credit  facilities  ("debt:equity  ratio"),  of not more than  50:50 and a
minimum  tangible net worth (as defined in such credit  facilities)  of at least
$1.5 billion.  At December 31, 2002, pursuant to these covenants and taking into
account the non-cash impairment charge taken by us in the second quarter of 2002
relating to the reduction in the net carrying  value of our Voisey's Bay project
and certain  other  assets and the charge  referred to above taken in the fourth
quarter  of 2002  relating  to our  Goro  project,  the  debt:equity  ratio  was
approximately 31:69 and our tangible net worth was $3.3 billion. There can be no
assurance that future material adverse developments would not result in a breach
of these covenants. If we are unable to maintain a debt:equity ratio of not more
than 50:50 and  tangible  net worth of at least $1.5  billion,  our bank lenders
generally  would  have the  right to  declare  a default  and  require  all then
outstanding loans to be repaid and pursue the various remedies available to them
under the bank  credit  facilities,  including  declining  to make any new loans
under such facilities. Any such action by the lenders could materially adversely
affect our ability to finance our operating and  development  projects,  and our
results of operations, financial condition and liquidity.


                                       12



EXCHANGE RATE FLUCTUATIONS


    Our  results of  operations  are  affected  by various  exchange  rates,  in
particular  between  the  Canadian  dollar and the U.S.  dollar and, to a lesser
extent,  other exchange  rates.  These exchange rates have varied  substantially
over time,  including over the last five years. For example, the Canadian dollar
has  strengthened  significantly  compared  to the U.S.  dollar to date in 2003,
rising from $0.6350 per Cdn.$1.00 on January 2, 2003 to $0.7367 per Cdn.$1.00 on
June 4, 2003. A substantial  portion of our revenue is received in U.S.  dollars
since  the  price of  nickel  and  other  metals  produced  by us are  generally
referenced  in U.S.  dollars,  while a  significant  portion  of our  costs  and
expenses are incurred in Canadian dollars. Our consolidated financial statements
are expressed in U.S.  dollars.  Fluctuations in exchange rates between the U.S.
dollar and the Canadian dollar and between the U.S. dollar and other  currencies
may give rise to foreign  currency  exposure,  either  favorable or unfavorable,
which  have  materially  impacted  and may in the future  materially  impact our
financial  results.  We from time to time hedge a portion of our Canadian dollar
and other  currency  requirements  to limit any adverse  effect of exchange rate
fluctuations  with  respect to our  Canadian  dollar and other  costs,  but such
hedges have not  eliminated  the  potential  material  adverse  effect that such
fluctuations could have on our results of operations or financial condition.

    Our results of operations  for the first quarter of 2003 were  significantly
adversely  affected by the  strengthening of the Canadian dollar compared to the
U.S. dollar during that period.  The Canadian dollar's  continued  strengthening
compared to the U.S. dollar since that time is expected to adversely  affect our
results of  operations  in the  second  quarter of 2003.  We  estimate  that the
current  approximate  full year impact of changes in the Canadian  dollar - U.S.
dollar exchange rate is that, for every one cent change in such  exchange  rate,
our basic earnings per share would be impacted by approximately $0.12.


INTEREST RATE AND COUNTERPARTY RISK

    Our  exposure  to changes in  interest  rates  results  from  investing  and
borrowing   activities   undertaken   to  manage  our   liquidity   and  capital
requirements.  We  generally  have used  fixed-rate  debt to  finance  long-term
investments,  while  variable-rate  debt has been used to meet  working  capital
requirements  and related  requirements on a more near-term basis. At the end of
2002,  we entered  into an interest  rate swap  agreement to manage the interest
rate risk  associated  with a portion of our fixed-rate  debt. The interest rate
swap changes our exposure to interest risk by  effectively  converting a portion
of our  fixed-rate  debt to a floating rate. We may elect in the future to enter
into interest rate swaps to effectively convert floating-rate debt to fixed-rate
debt and enter into additional  fixed-rate to  floating-rate  swaps. At December
31,  2002,  approximately  $448  million,  or 27 per cent,  of our total debt of
$1,643 million was effectively  subject to variable  interest rates.  Based upon
our level of debt that is effectively floating rate, as of December 31, 2002 the
impact of a 10 per cent change in interest  rates,  or 14 basis points (based on
certain benchmark  interest rates as at December 31, 2002), over the course of a
full year would change our interest  expense by less than $1 million over a full
year. As noted above, we may be required to raise  additional debt in the future
and,  accordingly,  we could be  materially  adversely  affected  by  changes in
interest  rates in the future despite any interest rate swaps we then might have
in effect.  Since  year-end  2002,  we have entered  into an interest  rate swap
covering 100 per cent of our $400 million  aggregate  principal amount of 7 3/4%
Notes due 2012 that  effectively  converts all of those  securities  to floating
rate debt and increases the  sensitivity  of our interest  expense to changes in
interest  rates  proportionately.  There can be no assurance that we will not be
materially   adversely   affected  by  interest  rate  changes  in  the  future,
notwithstanding our use of interest rate swaps.

    In addition,  our interest rate swaps,  metals hedging and foreign  currency
risk   management   activities   expose  us  to  the  risk  of  default  by  the
counterparties  to such  arrangements.  Any such  default  could have a material
adverse effect on our business and financial condition.


RISKS RELATING TO THE DEBENTURES

POSSIBLE VOLATILITY OF OUR COMMON SHARES

    The Debentures are convertible into common shares; accordingly, fluctuations
in the  market  price of our common  shares  may affect the market  price of the
Debentures. We cannot predict whether the market price of our common shares will
rise or fall.  Factors that will affect the trading  price of our common  shares
include the following: our operating results and future prospects; nickel prices
and expectations  concerning future nickel prices; material public announcements
by us or our  competitors;  the extent to which we pay  dividends  or make other
distributions  to  holders of our common  shares;  whether we or another  person
issues  securities  like the Debentures or issues or sells a large number of our
common  shares;  trading on the New York Stock  Exchange  and the Toronto  Stock
Exchange where our common shares are traded;  conditions in the capital  markets
generally;  and political,  financial and economic conditions.  In addition, the
common  shares have from time to time in recent  years  experienced  significant
price  and   volume   fluctuations   that   often   have  been   unrelated   and
disproportionate  to our  operating  performance.  See  "Price  Range of  Common
Shares" and "Dividend Policy".

                                       13



TERMS OF THE DEBENTURES

    No adjustment to conversion rate for accrued interest. The rate at which the
Debentures  are  convertible  into our common shares is not adjusted for accrued
interest.  Such accrued  interest will be fully satisfied by the delivery of the
common  shares  (or cash in lieu of  common  shares  or a  combination  thereof)
received upon conversion,  so a converting  holder will not necessarily  receive
any cash payment  representing  accrued  interest.  Because the number of common
shares  issuable upon  conversion of each Debenture is not increased even though
the  accreted  value of the  Debentures  (i.e.,  the issue  price  plus  accrued
interest)  increases  over time,  the implied  effective  conversion  price will
increase over time.

    Your conversion right is conditional.  The Debentures have several features,
including conditions to conversion,  which, if not satisfied,  could prevent you
from  converting your Debentures and result in you receiving less than the value
of our common shares into which the Debentures are otherwise convertible.  These
features  could  adversely  affect  the  value  and the  trading  prices  of the
Debentures. See "Description of Debentures--Conversion Rights".

    Adverse  consequence of original issue discount.  The Debentures were issued
at a substantial  discount  from their amount  payable at maturity,  which,  for
United  States  federal  income tax purposes,  is referred to as original  issue
discount.  As a result,  if you purchased the Debentures,  you generally will be
required to include amounts in gross income for United States federal income tax
purposes  prior to the  conversion,  redemption,  purchase  or  maturity  of the
Debentures  to which  such  income is  attributable.  See  "Certain  Income  Tax
Considerations--Certain      United      States      Federal      Income     Tax
Considerations--Original Issue Discount".

    The  Debentures  are  subject to early  redemption.  The  Debentures  may be
redeemed at our option at any time on or after March 19, 2010, in cash or common
shares, or a combination of cash and common shares, at the redemption prices set
forth in this prospectus,  together with any accrued and unpaid cash interest to
the  redemption  date.  You should  assume that this  redemption  option will be
exercised  if we are  able  to  refinance  at a  lower  interest  rate  or it is
otherwise in our interest to redeem the Debentures.

    A change in control may not result upon the occurrence of certain  important
corporate  events.   Certain  important  corporate  events,  such  as  leveraged
recapitalizations  that would increase the level of our indebtedness,  would not
constitute a "change in control"  under the  indenture and therefore not require
us to purchase the Debentures. See "Description of Debentures--Change in Control
Requires Offer to Purchase Debentures".

TRADING MARKET FOR THE DEBENTURES

    The Debentures  comprise a new issue of securities for which there may be no
trading  market.  The Debentures  are not listed on any  securities  exchange or
included  in any  automated  quotation  system.  The  Debentures  may trade at a
discount from their initial  offering  price,  depending on prevailing  interest
rates, the market for similar  securities,  the price of our common shares,  our
performance  and other factors.  We do not know whether an active trading market
will develop for the  Debentures.  To the extent that an active  trading  market
does not develop, the price at which you may be able to sell the Debentures,  if
at all, may be less than the price you pay for them in this offering.

INABILITY TO FUND PURCHASE OF DEBENTURES

    Upon the occurrence of specified  change in control  events  occurring on or
prior  to  March  14,  2010,  we will be  required  to  offer  to  purchase  all
outstanding  Debentures for cash,  common  shares,  or a combination of cash and
common shares.  However, it is possible that if we elect to pay all or a portion
of the  purchase  price in cash upon such a change in  control,  we may not have
sufficient  funds at that time to make the required  purchase of  Debentures  or
that restrictions in our credit  facilities or other  indebtedness may not allow
those purchases of Debentures for cash.


                                 USE OF PROCEEDS

     Neither the sale of any Debentures by any holders  thereof nor the issue of
any underlying shares will result in any proceeds to Inco.

                          PRICE RANGE OF COMMON SHARES

                                 DIVIDEND POLICY

    Our  dividend  policy,  under  normal  circumstances  and after  taking into
account our short-term and long-term needs and objectives, is to declare and pay
dividends on the common shares averaging approximately one-third of reported net
earnings  over a period of  years.  A  sustainable  level of  regular  quarterly
dividends would be paid,  adjusted,  when appropriate,  by extra dividends.  The
quarter-to-quarter  decision  as to the  amount of the  quarterly  dividend  per
common share is determined with reference to current  business  results and cash
needs.  In  February  1999,  our board of  directors  eliminated  the payment of
quarterly  dividends on our common shares.  This action was taken as part of our
other  actions to maintain our  financial  flexibility  in the  commodity  price
environment  prevailing at that time.  Our board of directors has reviewed,  and
will continue to review,  on a periodic  basis,  a possible  decision to restore
and, accordingly, declare and pay dividends on our common shares in the future.


                                EARNINGS COVERAGE

    For 2002,  we recorded  total  non-cash  charges of $1,626  million,  net of
deferred  income and mining taxes of $789  million,  under  Canadian  GAAP. As a
result  of these  non-cash  charges,  we had a net  loss,  before  deduction  of
interest and income and mining  taxes,  of $2,070  million for the twelve months
ended  December  31, 2002 and,  after giving  effect to our initial  offering of
Debentures and our  concurrent  offering of 3 1/2%  subordinated  debentures due
2052 (the "Subordinated Debentures"), as if made as of January 1, 2002, we would
have had a  deficiency  of $2,181  million in the amount  required  to cover our
interest  requirement of $111 million.  Excluding these non-cash charges,  after
giving effect to our initial offering of Debentures and our concurrent  offering
of Subordinated  Debentures,  as if made as of January 1, 2002, consolidated net
earnings,  before  deduction  of  interest  and income and mining  taxes of $345
million for the twelve months ended December 31, 2002, would have been 3.1 times
our interest  requirement for 2002 of $111 million.  If our initial  offering of
Debentures and our concurrent offering of Subordinated  Debentures had been made
as of April 1,  2002,  excluding  non-cash  charges  of $1,613  million,  net of
deferred  income and mining taxes of $785  million,  consolidated  net earnings,
before deduction of interest and income and mining taxes of $302 million for the
twelve  months  ended  March 31,  2003  would  have been 2.7 times our  interest
requirement  of $112  million.  As our  zero  coupon  convertible  notes  ("LYON
Notes"),  the Debentures and the  Subordinated  Debentures are treated as equity
for  Canadian  GAAP  purposes,  our  interest  requirement  does not include the
carrying charges associated with these securities. Had we accounted for the LYON
Notes, the Debentures and the Subordinated Debentures as debt, as is required by
U.S.  GAAP,  the  carrying  charges of the LYON Notes,  the  Debentures  and the
Subordinated  Debentures  would have been  reflected in interest  expense and we
would have had a deficiency of $2,193  million and $2,220  million in the amount
required to cover our interest  requirement for the twelve months ended December
31, 2002 and March 31, 2003, respectively.

    The information included in this section is based upon our audited financial
statements  prepared in accordance  with

                                       15



Canadian GAAP,  which differ in certain  material  respects from U.S. GAAP. As a
result of the above-referenced  non-cash charges,  which totaled $2,247 million,
net of deferred income and mining taxes of $947 million, for U.S. GAAP purposes,
we had a net loss,  before  deduction  of the  cumulative  effect of a change in
accounting  principles  of $18  million,  interest  and  income  and  mining tax
expenses,  of $2,867  million for the twelve months ended December 31, 2002 and,
after giving  effect to our initial  offering of Debentures  and our  concurrent
offering of Subordinated Debentures,  as if made as of January 1, 2002, we would
have had a  deficiency  of $2,990  million in the amount  required  to cover our
interest  requirement  of $123 million for the twelve months ended  December 31,
2002.  Excluding  these  non-cash  charges,  after giving  effect to our initial
offering of Debentures and our concurrent offering of Subordinated Debentures as
if made as of January 1, 2002,  consolidated  net earnings,  before deduction of
interest and income and mining taxes of $327 million for the twelve months ended
December 31, 2002,  would have been 2.7 times our interest  requirement  of $123
million.   If  our  offering  of  Debentures  and  our  concurrent  offering  of
Subordinated  Debentures  had  been  made as of  April 1,  2002,  excluding  the
cumulative effect of a change in accounting principles of $18 million,  non-cash
charges of $2,234  million,  net of  deferred  income  and mining  taxes of $943
million,  consolidated net earnings, before deduction of interest and income and
mining taxes of $287 million for the twelve  months ended March 31, 2003,  would
have  been 2.3 times our  interest  requirement  of $124  million.  For  further
information  regarding the differences  between Canadian GAAP and U.S. GAAP, see
Note 22 to our consolidated  financial  statements included as an Exhibit to our
2002 10-K .


                                     RATINGS

    On March 6, 2003,  Standard & Poor's  Corporation  ("S&P") assigned a "BBB-"
rating  to the  Debentures  and  Moody's  Investors  Service,  Inc.  ("Moody's")
assigned a "Baa3" rating to the Debentures.


    Credit ratings are intended to provide investors with an independent measure
of credit quality of any issue of securities. The credit ratings accorded to the
Debentures by the rating agencies are not  recommendations to purchase,  hold or
sell the Debentures.  Each rating should be evaluated independently of any other
rating.  These is no  assurance  that any rating  will  remain in effect for any
given  period  of time or that any  rating  will  not be  revised  or  withdrawn
entirely by a rating  agency in the future if in its judgment  circumstances  so
warrant.


    S&P's credit  ratings are on a long-term  debt rating scale that ranges from
AAA to D,  which  represents  the range from  highest to lowest  quality of such
securities rated.  According to the S&P rating system, debt securities rated BBB
exhibit  adequate  protection  parameters.  However,  insofar as a BBB rating is
concerned, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial  commitments
on the securities. The ratings from AA to CCC may be modified by the addition of
a plus  (+) or  minus  (-)  sign to show  relative  standing  within  the  major
categories.

    Moody's credit ratings are on a long-term debt rating scale that ranges from
Aaa to C, which  represents  the range from  highest to lowest  quality for such
securities rated.  According to the Moody's rating system, debt securities rated
Baa are considered as medium grade obligations, that is, they are neither highly
protected nor poorly secured.  Interest  payments and principal  security appear
adequate for the present but certain  protective  elements may be lacking or may
be characteristically  unreliable over any great length of time. Such securities
lack  outstanding  investment  characteristics  and  in  fact  have  speculative
investment characteristics as well. Moody's applies numerical modifiers 1, 2 and
3 in each generic  rating  classification  from Aa through Caa in its  corporate
bond rating system.  The modifier 1 indicates that the issue ranks in the higher
end of its generic rating category, the modifier 2 indicates a mid-range ranking
and the  modifier  3  indicates  that the  issue  ranks in the  lower end of its
generic rating category.


                            DESCRIPTION OF DEBENTURES

    The Debentures  were issued under an indenture dated as of March 7, 2003, as
supplemented  by a first  supplemental  indenture  dated as of  March  7,  2003,
between us and The Bank of New York, as trustee.  References in this description
to  the  indenture  are to  the  indenture  as so  supplemented.  The  following
description  summarizes  the  material  provisions  of the  Debentures  and  the
indenture.  The following summary does not purport to be complete and is subject
to, and qualified by reference to, the definitions  and other  provisions of the
indenture.  As used in this description,  the words "we", "us", "our" and "Inco"
do not include any of our current or future subsidiaries.


GENERAL

    The  Debentures  are limited to  $272,679,000  aggregate  amount  payable at
maturity.  The  Debentures  mature on March 14,  2023.  The  amount  payable  at

                                       16



maturity of each  Debenture is $1,000.  We may, at our option,  elect to pay the
amount  payable at maturity in cash or our common shares or any  combination  of
cash and  common  shares.  If we elect to pay all or any part of this  amount in
common shares,  the number of common shares we will deliver will be equal to the
portion of the amount to be paid in common shares  divided by the average market
price of one  common  share,  which  we  define  under  "--Delivery  of  Shares;
Fractional Shares". The Debentures are payable at the office of the paying agent
(currently,  the trustee),  or an office or agency we maintain for this purpose,
in the Borough of Manhattan,  The City of New York. We discuss the tax treatment
of payments to holders in respect of the Debentures  under  "Certain  Income Tax
Considerations".

    The  Debentures  were offered at a  substantial  discount  from their amount
payable at maturity.  See  "Certain  Income Tax  Considerations--Certain  United
States  Federal  Income  Tax  Considerations--Original   Issue  Discount".  Each
Debenture  was  issued at an issue  price of  $913.81  per  Debenture.  Interest
accrues on the issue price of a Debenture in the period during which a Debenture
remains  outstanding  at a rate  of  1.5%  per  year  compounded  semi-annually.
However,  prior to stated maturity,  we will only pay interest in cash at a rate
of  1.0943%  per year on the  issue  price of the  Debentures.  The rate of cash
interest  and the amount  payable at maturity  over the issue price  represent a
yield to maturity of 1.5% computed on a semi-annual  bond equivalent basis using
a 360-day year composed of twelve 30-day  months.  Such accrual will commence on
the issue  date for the  Debentures  of March 7,  2003.  The  amount  payable at
maturity of a Debenture  represents the issue price plus accrued interest to the
stated maturity date of March 14, 2023.

    Only cash interest at a rate of 1.0943% per year on the issue price from the
issue  date of the  Debentures,  or from the  most  recent  date to  which  cash
interest has been paid or duly provided,  will be paid on the  Debentures  until
the Debentures  are converted in accordance  with the indenture or paid in full,
or until funds or common shares,  or any combination of funds and common shares,
are made  available for their payment in full in accordance  with the indenture.
Cash interest is payable at the stated  maturity (or earlier date of redemption,
purchase or, in certain circumstances,  conversion) and semi-annually in arrears
on March 14 and  September 14 of each year,  beginning on September  14, 2003 to
holders  of record  at the  close of  business  on the  March 1 or  September  1
(whether or not a business day)  immediately  preceding  such  interest  payment
date.  Each payment of cash  interest on the  Debentures  includes cash interest
accrued  through  the day before the  applicable  interest  payment  date or the
stated maturity (or earlier purchase,  redemption or, in certain  circumstances,
conversion),  as the case may be. Any  payment  required  to be made on any date
that is not a business day will be made on the next  succeeding  business day as
if made on the date that  payment  was due and no cash  interest  will accrue on
that  payment for the period from and after the date that payment was due to the
date of  payment  on the  next  succeeding  business  day.  In the  event of the
maturity, conversion,  purchase or redemption of a Debenture as described below,
all  interest  will  cease to  accrue on such  Debenture  under the terms of and
subject to the conditions in the indenture.  We may not reissue a Debenture that
has  matured or been  converted,  purchased,  redeemed or  otherwise  cancelled,
except for registration of transfer, exchange or replacement of such Debenture.

    Debentures  may be presented for  conversion at the office of the conversion
agent,  and for  exchange  or  registration  of  transfer  at the  office of the
registrar. The trustee is currently the conversion agent and registrar.

    The   indenture   limits  our  right  to  pledge  our  and  certain  of  our
subsidiaries' assets and to engage in some sale and leaseback  transactions,  as
described below under "--Certain Covenants",  but it does not limit our right to
incur  additional  indebtedness  or pay dividends or contain any other financial
covenants.  These  provisions  of the  indenture  would not  necessarily  afford
holders  of the  Debentures  protection  from a  decline  in the  value of their
investment in the event of a highly leveraged or other transaction  involving us
that may adversely affect such holders.


BOOK-ENTRY SYSTEM

    The  Debentures  were  issued in the form of two global  securities  held in
book-entry form. The Depository Trust Company ("DTC") or its nominee is the sole
registered holder of the Debentures for all purposes under the indenture. Owners
of beneficial  interests in the Debentures  represented by the global securities
hold such interests  pursuant to DTC's  procedures  and practices.  As a result,
beneficial  interests in any such securities are shown on, and transfers thereof
are only effected through, records maintained by DTC and its direct and indirect
participants  and any  such  interests  may not be  exchanged  for  certificated
securities, except in limited circumstances. Owners of beneficial interests must
exercise  any rights in  respect of their  interests  in  accordance  with DTC's
procedures and practices. Beneficial owners are not holders and are not entitled
to any rights  under the global  securities  or the  indenture  provided  to the
holders of the  Debentures.  Inco and the trustee,  and any of their  respective
agents,  may treat DTC as the sole  holder  and  registered  owner of the global
securities. See "Legal Ownership" below.

    DTC has  advised us that it is a  limited-purpose  trust  company  organized
under the New York Banking Law, a "banking  organization"  within the meaning of
the New York Banking Law, a member of the Federal  Reserve  System,  a "clearing
corporation"  within the meaning of the New York Uniform  Commercial  Code and a
"clearing  agency"  registered  pursuant to the provisions of Section 17A of the
U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"). DTC holds
securities that its participants  deposit with it and facilitates the settlement
among  participants of securities  transactions in

                                       17



deposited  securities  through  electronic  computerized  book-entry  changes in
participants'  accounts,  thereby  eliminating the need for physical movement of
securities  certificates.  Participants  include securities brokers and dealers,
banks, trust companies,  clearing  corporations and certain other organizations.
DTC is owned by a number of its participants and by the New York Stock Exchange,
Inc., The American Stock Exchange LLC and the National Association of Securities
Dealers,  Inc. Access to DTC's book-entry system is also available to securities
brokers and dealers, banks and trust companies, and others that clear through or
maintain  a  custodial  relationship  with a  participant,  either  directly  or
indirectly.  The rules  applicable to DTC and its  participants are on file with
the Securities and Exchange Commission (the "SEC").


RANKING OF DEBENTURES

    The Debentures are unsecured and unsubordinated obligations.  The Debentures
rank on parity in right of payment with all of our existing and future unsecured
and unsubordinated indebtedness.


CONVERSION RIGHTS

    A holder may convert its  outstanding  Debentures,  in  multiples  of $1,000
amount  payable at maturity,  into our common shares prior to 5:00 p.m. New York
City time at stated maturity only under the circumstances  described below. If a
holder has submitted a holder  redemption notice or a change in control purchase
notice requiring us to redeem or purchase any Debentures, the holder may convert
these  Debentures  as described in this section only if the holder has withdrawn
its holder  redemption notice or change in control purchase notice in accordance
with the requirements of the indenture.

    A holder may convert a Debenture into common shares only under the following
circumstances:

    o   in a calendar quarter (and only during such calendar quarter)  beginning
        with the quarter ending September 30, 2003 if, as of the last day of the
        immediately  preceding  calendar quarter,  the closing sale price of our
        common  shares  for  at  least  20  trading  days  in the  period  of 30
        consecutive  trading  days  ending  on the  last  trading  day  of  such
        preceding quarter is more than 120% of the accreted conversion price (as
        defined  below)  per  common  share  on the  last  trading  day of  such
        preceding quarter; or

    o   during  the  five  business-day  period  following  any ten  consecutive
        trading-day period in which the trading price of the Debentures for each
        day of such period was less than 95% of the product of the closing  sale
        price of our common shares  multiplied by the conversion  rate in effect
        for that period; or

    o   if the Debentures have been called for redemption; or

    o   upon  the  occurrence of  the corporate  events  described  below  under
        "--Conversion upon Specified Corporate Events".

                                       18



CONVERSION UPON SATISFACTION OF MARKET PRICE CONDITION

    A holder may surrender any of its Debentures for conversion  into our common
shares in a calendar  quarter (and only during such quarter)  beginning with the
quarter  ending  September 30, 2003,  if, as of the last day of the  immediately
preceding  calendar quarter,  the closing sale price of our common shares for at
least 20 trading days in the period of 30 consecutive trading days ending on the
last  trading day of such  preceding  quarter is more than 120% of the  accreted
conversion  price per common  share on the last  trading  day of such  preceding
quarter.  The "accreted conversion price" per share as of any day will equal the
sum of the issue price of the  Debenture  plus accrued  interest  divided by the
number of  shares  issuable  upon  conversion  of a  Debenture,  subject  to any
adjustments to the conversion rate through that date.

    The "closing  sale price" of the common shares on any date means the closing
sale  price per  common  share (or if no closing  sale  price is  reported,  the
average  of the bid and ask  prices  or, if more than one in  either  case,  the
average of the  average bid and the average ask prices) on such date as reported
in composite  transactions for the principal U.S.  securities  exchange on which
the common shares are traded  (currently  being the New York Stock Exchange) or,
if the common  shares are not listed on a U.S.  national or regional  securities
exchange,  as reported by the Nasdaq System or, if no such price is reported, as
reported by the  principal  non-United  States market on which the common shares
are  traded  (currently  being the  Toronto  Stock  Exchange),  such price to be
converted  into U.S.  dollars  based on the Bank of Canada noon exchange rate as
reported for conversion  into U.S.  dollars on such date. In the absence of such
quotation,  we will  determine  the  closing  sale  price  on the  basis of such
quotations as we consider appropriate.

CONVERSION UPON SATISFACTION OF TRADING PRICE CONDITION

    A holder may surrender any of its Debentures for conversion  into our common
shares prior to stated maturity during the  five-business  day period  following
any ten  consecutive  trading-day  period  in  which  the  trading  price of the
Debentures  for each day of that  period  was less or was deemed to be less than
95% of the product of the closing sale price of our common shares  multiplied by
the applicable conversion rate.

    The "trading price" of the Debentures on any date of determination means the
average of the secondary  market bid  quotations  per Debenture  obtained by the
conversion agent for $5,000,000  amount payable at maturity of the Debentures at
approximately 3:30 p.m., New York City time, on such determination date from two
independent nationally recognized securities dealers we select; provided that if
the conversion  agent cannot  reasonably  obtain at least two such bids, but can
reasonably  obtain one such bid, this one bid shall be used. If for any date the
conversion agent cannot reasonably obtain at least one bid for $5,000,000 amount
payable at maturity of the Debentures  from a nationally  recognized  securities
dealer or in our reasonable  judgment,  the bid quotations are not indicative of
the  secondary  market value of the  Debentures,  then the trading  price of the
Debentures  for that date will be deemed to be less than 95% of the  product  of
the  closing  sale  price of our  common  shares  multiplied  by the  applicable
conversion rate.

    The  conversion  agent shall be obligated to determine  the trading price of
the  Debentures  only upon our  request.  We must make such a request  only if a
holder  provides  us with  reasonable  evidence  that the  trading  price of the
Debentures  would be less than 95% of the product of the  closing  sale price of
our common shares and the applicable  conversion rate for the applicable period.
If a holder  provides such evidence,  we will instruct the  conversion  agent to
determine the trading price of the Debentures for the applicable period.

CONVERSION UPON NOTICE OF REDEMPTION

    If we  call  the  Debentures  for  redemption,  a  holder  may  convert  the
Debentures from the date of the notice of redemption until the close of business
on the business day immediately  preceding the redemption date, after which time
the right to convert will expire unless we fail to pay the redemption price.


CONVERSION UPON SPECIFIED CORPORATE EVENTS

    If we elect to:

    o   distribute to all holders of our common shares certain rights  entitling
        them to  purchase,  for a period  expiring  within 45 days,  our  common
        shares at less than the then current market price (measured by averaging
        the  closing  sale prices of our common  shares for the 10 trading  days
        preceding   the  date  of  the  first   public   announcement   of  such
        distribution); or

    o   distribute to all holders of our common shares,  assets, debt securities
        or certain rights to purchase our securities,  which  distribution has a
        per share value  exceeding  15% of the closing  sale price of our common
        shares on the day preceding the date of the first public announcement of
        such distribution;

we must  notify the holders at least 10 days prior to the  ex-dividend  date for
the  distribution.  Once we have given this  notice,  the holders may  surrender
Debentures for conversion at any time until the earlier of the close of business
on the business day prior to the ex-dividend date or any announcement by us that
the distribution will not take place. No distribution will entitle the holder of
a  Debenture  to  convert  if the  holder  would  otherwise  participate  in the
distribution without conversion.

    In addition, if

    o   we are a  party  to a  consolidation,  amalgamation,  merger,  statutory
        arrangement  (involving  a  business  combination)  or  sale  of  all or
        substantially all of our consolidated assets;

    o   we are not the resulting or surviving entity;

    o   the transaction is not with one of our affiliates; and

    o   after the transaction, either

        o   more than 50% of the  surviving or resulting  entity's  total voting
            power is not held by our pre-transaction shareholders, or

                                       19



        o   more than 50% of the surviving or resulting  entity's directors were
            not  directors of ours or approved by our  pre-transaction  board of
            directors,

then holders may surrender  Debentures for conversion at any time from and after
the  date  that  is 15  days  prior  to the  anticipated  effective  date of the
transaction  until and  including the date that is 15 days after the actual date
of such transaction.  If the transaction also constitutes a "change in control,"
as defined below, the holder instead can require us to purchase all or a portion
of its  Debentures as described  under  "--Change in Control  Requires  Offer to
Purchase Debentures".

CONVERSION RATE AND CONVERSION PROCEDURES

    The  initial  conversion  rate is 31.9354  common  shares per $1,000  amount
payable at maturity of the Debentures, subject to adjustment upon the occurrence
of the events described below. This is equivalent to an initial conversion price
of  approximately  $28.61 per common share. On conversion,  we will pay cash for
any  fractional  shares  in an  amount  equal to  their  average  market  price,
determined as described under "--Delivery of Shares; Fractional Shares". We will
have the option to deliver  cash in lieu of some or all of the common  shares to
be  delivered  upon  conversion  of the  Debentures.  We will give notice of our
election to deliver part or all of the conversion  consideration  in cash to the
holder  converting the Debentures within two business days of our receipt of the
holder's  notice of conversion  unless we have already  informed  holders of our
election  in  connection  with our  optional  redemption  of the  Debentures  as
described under  "--Redemption  of Debentures at the Option of Inco". The amount
of cash to be  delivered  per  Debenture  will be equal to the  number of common
shares in respect of which the cash  payment  is being  made  multiplied  by the
average of the closing sale prices of our common shares on the five  consecutive
trading days  commencing one day after (a) the date of our notice of election to
deliver part or all of the conversion consideration in cash if we have not given
notice of redemption,  or (b) the  conversion  date, in the case of a conversion
following our notice of redemption specifying our intention to deliver cash upon
conversion.

    If we  elect to  deliver  cash in lieu of some or all of the  common  shares
issuable upon  conversion,  we will make the payment,  including the delivery of
any common  shares,  through  the  conversion  agent,  to  holders  surrendering
Debentures no later than the tenth business day following the  conversion  date.
Otherwise,  we will  deliver  the  shares,  together  with any cash  payment for
fractional shares, through the conversion agent no later than the fifth business
day following the conversion date. We may not deliver cash in lieu of any common
shares issuable upon a conversion (other than cash in lieu of fractional shares)
if an Event of  Default  with  respect to the  Debentures  has  occurred  and is
continuing, other than a default in payment of the conversion consideration.  We
discuss  the  tax  treatment  upon   conversion   under   "Certain   Income  Tax
Considerations--     Certain     United     States     Federal     Income    Tax
Considerations--Disposition or Conversion of the Debentures" and "Certain Income
Tax      Considerations--Certain      Canadian      Federal      Income      Tax
Considerations--Ownership of Debentures".

    Except as noted  below,  on  conversion  of a Debenture  the holder will not
receive any cash payment representing accrued interest. Accordingly,  Debentures
surrendered  for  conversion  by a holder  during the  period  from the close of
business  on any  regular  record  date to the  opening of  business of the next
interest  payment  date,  except for  Debentures to be redeemed on a date within
this period or on the next interest payment date, must be accompanied by payment
of an amount equal to the cash interest that the registered holder is to receive
on the  Debenture.  Our  delivery  to the  holder of the fixed  number of common
shares into which the  Debenture is  convertible  together with any cash payment
for fractional shares, or cash in lieu of such common shares, will fully satisfy
our  obligation  to pay the issue price of the Debenture  plus accrued  interest
attributable to the period from the issue date through the conversion date. As a
result,  accrued  interest  is  deemed  paid  in  full  rather  than  cancelled,
extinguished or forfeited.

    To exercise its conversion right, a holder must:

    o   complete and manually sign an original or facsimile copy of a conversion
        notice and deliver such conversion notice to the conversion agent;

    o   surrender the Debenture to the conversion agent;

    o   if required by the conversion agent,  furnish  appropriate  endorsements
        and transfer documents; and

    o   if required, pay all transfer or similar taxes.

    Pursuant  to  the  indenture,  the  date  on  which  all  of  the  foregoing
requirements have been satisfied is the conversion date.

    Beneficial holders of Debentures who wish to convert a Debenture into common
shares must do so in accordance with the procedures established by DTC.

                                       20



    The conversion rate will be adjusted for:

    o   dividends or  distributions on common shares payable in common shares or
        other shares;

    o   subdivisions or combinations of common shares;

    o   distributions  to all  holders  of common  shares of  certain  rights to
        purchase common shares for a period expiring within 45 days at less than
        the current market price per common share, as defined below,  subject to
        certain conditions;

    o   distributions   to  all  holders  of  common   shares  of  evidences  of
        indebtedness,  equity  securities  (other than  common  shares) or other
        assets  (other  than  cash  dividends  or cash  distributions  described
        below);

    o   distributions  consisting of cash to all holders of our common shares in
        an  aggregate  amount  that,  when  combined  with  (a)  other  all cash
        distributions  made within the  preceding 12 months and (b) the cash and
        the fair market  value,  as of the date of  expiration  of the tender or
        exchange offer referred to below, of the  consideration  paid in respect
        of any tender or exchange  offer by us or a  subsidiary  of ours for our
        common shares  concluded  within the preceding 12 months,  exceeds 5% of
        the product of the current market price of our common shares  multiplied
        by the number of common  shares then  outstanding  on the date fixed for
        the determination of shareholders entitled to receive the distribution;

    o   the  successful  completion of a tender or exchange  offer made by us or
        any  subsidiary of ours for our common shares that involves an aggregate
        consideration  that,  when  combined  with any cash and the fair  market
        value of other  consideration  payable in respect of any other tender or
        exchange  offer  by us or a  subsidiary  of ours for our  common  shares
        concluded  within the preceding 12 months,  exceeds 5% of the product of
        the current  market price of our common shares  multiplied by the number
        of common  shares  then  outstanding  on the date of  expiration  of the
        tender or exchange offer; and

    o   any  reclassification of our common shares or any reorganization or sale
        of Inco in which  holders of our common  shares are  entitled to receive
        common equity,  other securities or other property or assets in exchange
        for such common shares.

    For  the  purpose  of  (1)  cash  distributions  and  (2)  distributions  in
connection  with a tender or exchange offer as described  above,  any adjustment
required for a cash  distribution or distribution in connection with a tender or
exchange offer would be based upon the amount by which such distribution exceeds
the  amount  permitted  to be  excluded.  Any  adjustment  based  on  any  other
distribution would be based upon the full amount of the distribution.

    The "current  market  price" per common share on any date shall be deemed to
be the average of the daily closing sale price for the five consecutive  trading
days ending on the earlier of the day in question and the day before the related
ex-date with respect to any distribution, issuance or other event requiring such
computation.

    The conversion rate will not be adjusted for accrued interest.  Furthermore,
no adjustment need be made unless such  adjustment  would require an increase or
decrease of at least 1%. The  indenture  permits us to increase  the  conversion
rate from time to time.

    Our  Shareholder  Rights Plan  Agreement  provides that each common share of
Inco,  including  any we  issue  at the  stated  maturity  or  upon  conversion,
redemption  or  purchase  of the  Debentures,  issued  at any time  prior to the
distribution of separate certificates  representing our rights, will be entitled
to receive  such  rights.  However,  there  shall not be any  adjustment  to the
conversion privilege or conversion rate as a result of:

    o   the  issuance of the rights to purchase  common  shares  pursuant to our
        Shareholder Rights Plan Agreement or any successor agreement;

    o   the distribution of any entitlement to receive the common share purchase
        rights;

    o   the  exercise  or  redemption  of such  rights  in  accordance  with our
        Shareholder Rights Plan Agreement; or

    o   the  termination or  invalidation of the common share purchase rights or
        similar rights.

                                       21



    We describe  the  Shareholder  Rights Plan  Agreement  in more detail  under
"Description of Share Capital-- Shareholder Rights Plan".

    If we are party to a  consolidation,  amalgamation,  merger or binding share
exchange or a transfer of all or substantially  all of our assets,  the right to
convert a  Debenture  into our  common  shares  may be  changed  into a right to
convert it into the kind and amount of securities,  cash or other assets of Inco
or  another  person  which the  holder  would  have  received  if the holder had
converted  its  Debentures  immediately  prior  to such  event  or  transaction.
However,  if  such  event  or  transaction  occurs  before  March  7,  2008  the
consideration  into which the Debentures will be convertible  will be limited to
Inco common  shares or other  prescribed  securities  (within the meaning of the
Income Tax Act (Canada) (the  "Canadian Tax Act")),  which  includes  shares not
redeemable  by the holder within five years after their issue.  As a result,  in
these  circumstances,  the consideration  issuable on exercise of the conversion
right  could  differ  from the  consideration  received by the holders of common
shares  pursuant to the event or  transaction,  but the conversion rate would be
adjusted so that the consideration  into which the Debentures are convertible is
equivalent in value at the date of the event or  transaction to the value of the
consideration  received by the holders of common shares pursuant to the event or
transaction.

    Holders of the Debentures may, in certain  circumstances,  be deemed to have
received a distribution  subject to U.S. federal income tax as a dividend in the
amount of:

    o   a taxable  distribution  to holders of common shares which results in an
        adjustment of the conversion rate; or

    o   an increase in the conversion rate at our discretion.

See "Certain Income Tax Considerations--Certain United States Federal Income Tax
Considerations--Constructive Dividend".

    The exercise of our option to restate the amount  payable at maturity of the
Debentures  to include all accrued  interest to date  following a Tax Event will
not affect the number of our  common  shares the holder is  entitled  to receive
upon  conversion  of a Debenture.  See  "--Optional  Conversion to Full Cash Pay
Debentures upon a Tax Event".


REDEMPTION OF DEBENTURES AT THE OPTION OF THE HOLDERS

    On March 14 in each of 2010,  2014 and 2018,  we will,  at the option of the
holder,  be required to redeem,  at the redemption  prices set forth below,  any
outstanding  Debenture  for which a written  holder  redemption  notice has been
properly  delivered by the holder to the trustee and not  withdrawn,  subject to
certain  additional  conditions.  We may also add one or more holder  redemption
dates on which  holders may  require us to redeem  outstanding  Debentures  at a
special  redemption  rate.  Prior to or on any  scheduled or  additional  holder
redemption  date, we may also offer  additional  consideration to be received to
induce  holders  not to  exercise  a holder  redemption  right.  We are under no
obligation,  however,  to add  any  holder  redemption  dates  or to  offer  any
additional consideration.  Holders may submit their Debentures for redemption to
the paying agent at any time from the opening of business on the date that is 29
business days prior to the holder redemption date until the close of business on
the date that is nine business days prior to the holder redemption date.

    The  redemption  price,  which  consists  of the issue  price  plus  accrued
interest, excluding cash interest, at each holder redemption date, will be:

    o   $941.15 per Debenture on March 14, 2010;

    o   $958.05 per Debenture on March 14, 2014; and

    o   $976.00 per Debenture on March 14, 2018.

    If prior to a holder  redemption  date we have elected to restate the amount
payable at maturity of the  Debentures  following the occurrence of a Tax Event,
the  redemption  price  will be  equal to the  restated  principal  amount.  See
"--Optional Conversion to Full Cash Pay Debentures Upon a Tax Event".

    We may, at our option, elect to satisfy our obligation to pay the redemption
price by  delivering  common  shares in lieu of some or all of the cash  payment
based on the  average  market  price of one common  share.  See  "--Delivery  of
Shares; Fractional Shares".

    In each case, in addition to the  redemption  price we will also pay accrued
and unpaid cash interest to the date of

                                       22



redemption.

    We will be required to give notice on a date not less than 29 business  days
prior to any holder  redemption  date to all holders at their addresses shown in
the  register  of the  registrar,  and to  beneficial  holders  as  required  by
applicable law,  detailing the procedures that holders must follow to require us
to redeem their Debentures.  In addition,  we will be required to give notice on
the date that is eight business days prior to any holder  redemption date to all
holders  at their  addresses  shown in the  register  of the  registrar,  and to
beneficial holders as required by applicable law, stating:

    o   whether we will pay the redemption  price in cash or common  shares,  or
        any combination thereof, specifying the percentages of each;

    o   if we elect to pay any part of the  redemption  price in common  shares,
        the method of calculating the average market price of the common shares;
        and

    o   the  procedures   that  holders  must  follow  to  withdraw  any  holder
        redemption notice with respect to the Debentures.

    After we have given  notice that we will  deliver  common  shares in lieu of
some or all of the cash  payable,  we may not change the number or percentage of
common  shares to be  delivered  in lieu of cash  payment,  except as  described
below.

    A holder of a  Debenture  otherwise  entitled  to a  fractional  share  will
receive cash in an amount equal to the value of such  fractional  share based on
the average market price. See "--Delivery of Shares;  Fractional Shares".  For a
discussion of the tax treatment upon exercise of a holder  redemption right, see
"Certain  Income Tax  Considerations--Certain  United States  Federal Income Tax
Considerations--Disposition or Conversion of the Debentures" and "Certain Income
Tax      Considerations--Certain      Canadian      Federal      Income      Tax
Considerations--Ownership of Debentures".

    To  exercise  the  holder  redemption  right,  on or prior  to the  close of
business on the date that is nine business  days prior to the holder  redemption
date, a holder must:

    o   complete  and manually  sign an original or  facsimile  copy of a holder
        redemption  notice and  deliver  such  holder  redemption  notice to the
        paying  agent,  in each  case  indicating  the  exercise  of the  holder
        redemption right;

    o   if required by the conversion agent,  furnish  appropriate  endorsements
        and transfer documents;

    o   if required, pay all transfer or similar taxes; and

    o   if we  elect to  deliver  common  shares  in lieu of some or all of cash
        payable,  but any of the  conditions to the delivery of common shares is
        not  satisfied  prior to the close of business on the holder  redemption
        date, indicate whether the holder elects:

             (1) to withdraw the holder  redemption  notice as to some or all of
         the Debentures to which it relates, or

             (2) to receive cash in respect of the entire  redemption  price for
         all  Debentures  or  portions  of  Debentures  subject  to such  holder
         redemption notice.

    If the holder  fails to  indicate  its choice with  respect to the  election
described in the final  bullet  point above,  the holder shall be deemed to have
elected to  receive  cash in  respect  of the  entire  redemption  price for all
Debentures subject to the holder redemption notice.

    A holder may  withdraw any holder  redemption  notice by  delivering  to the
conversion  agent a written notice of withdrawal  prior to the close of business
on the holder redemption date. The notice of withdrawal must state:

    o   the amount payable at maturity of the Debentures being withdrawn;

    o   the certificate numbers of the Debentures being withdrawn; and

    o   the amount payable at maturity,  if any, of the  Debentures  that remain
        subject to the holder redemption right.

    Beneficial  holders of Debentures who wish to exercise the holder redemption
right  or  withdraw  a  previous  exercise  must do so in  accordance  with  the
procedures established by DTC.

                                       23



    Because the market  price of our common  shares is  determined  prior to the
applicable  holder  redemption  date,  in the event we elect to  deliver  common
shares in lieu of some or all of the cash payable,  holders of  Debentures  bear
the market  risk with  respect to the value of the common  shares to be received
from the date such market price is determined to such holder redemption date.

    Upon  determination of the actual number of common shares in accordance with
the foregoing  provisions,  we will publish such  information  on our website or
through such other public medium as we may use at that time.

    For any holder  redemption  date,  our right to deliver  common  shares upon
exercise  of a holder  redemption  right,  in whole or in part,  is  subject  to
various conditions, including:

    o   listing of the common shares on the principal  United States or Canadian
        securities  exchange  on which our common  shares are then listed or, if
        not so listed, on Nasdaq;

    o   the information  necessary to calculate the average market price must be
        published  daily in a newspaper  of national  circulation  in the United
        States or on our website or through such other  public  medium as we may
        use at that time;

    o   the  registration  of our common shares under the Securities Act and the
        Exchange Act, if required; and

    o   any necessary  qualification  or  registration  under  applicable  state
        securities   laws  or  the   availability  of  an  exemption  from  such
        qualification and registration.

    If these  conditions are not satisfied with respect to a holder prior to the
close of  business on the holder  redemption  date,  we will pay the  redemption
price to the holders of Debentures entirely in cash.

    In connection with any holder redemption, we will:

    o   comply  with the  provisions  of Rule  13e-4,  Rule  14e-1 and any other
        tender offer rules under the  Exchange  Act and Canadian  laws which may
        then be applicable; and

    o   if required, file a Schedule TO or any other schedule under the Exchange
        Act which may then be applicable.

    To the extent any time  period set forth in the  indenture  is  inconsistent
with  the  requirements  of the  Exchange  Act  or  Canadian  law  or any  rules
thereunder, we will comply with the provisions of such laws or rules.

    Payment  of  the  redemption  price  for a  Debenture  for  which  a  holder
redemption  notice had been  delivered and not validly  withdrawn is conditioned
upon delivery of the  Debenture,  together with necessary  endorsements,  to the
paying agent at any time after delivery of the holder redemption notice. Payment
of the redemption  price for the Debenture  will be made promptly  following the
later of the holder redemption date or the time of delivery of the Debenture.

    If the paying  agent holds  money or  securities  sufficient  to satisfy the
redemption  price for the  Debenture on the business  day  following  the holder
redemption date in accordance with the terms of the indenture, then, immediately
after the holder redemption date, the Debenture will cease to be outstanding and
interest on such Debenture will cease to accrue, whether or not the Debenture is
delivered to the paying agent. Thereafter,  all other rights of the holder shall
terminate, other than the right to receive the redemption price upon delivery of
the Debenture.

    Our  ability to redeem  Debentures  with cash may be limited by the terms of
our then existing borrowing agreements.

    We may not redeem Debentures for cash (other than cash in lieu of fractional
shares) if an Event of Default with respect to the  Debentures  has occurred and
is continuing,  other than a default in the payment of the redemption price with
respect to such Debentures.


REDEMPTION OF DEBENTURES AT THE OPTION OF INCO

    No sinking fund is provided for the  Debentures.  Except as described  below
under  "--Redemption for Tax Reasons",  we may only redeem the Debentures at our
option on or after March 19, 2010.  In  addition,  we may extend the time during
which we may not  redeem the  Debentures  upon  providing  notice by mail to the
holders of the  Debentures.  We may redeem all or a portion of the Debentures in
cash, common shares or a combination thereof. The redemption price will be equal
to the issue

                                       24



price per Debenture plus accrued  interest to the redemption  date. We will give
not less  than 20  business  days'  nor more than 60  business  days'  notice of
redemption  by mail to holders of  Debentures.  The  notice of  redemption  will
inform the holders of our  election to deliver  common  shares or to pay cash in
lieu of delivery of common shares with respect to any Debentures converted after
such notice and prior to the redemption  date. If we elect to pay the redemption
price, in whole or in part, in common shares,  the number of common shares to be
delivered by us will be equal to the portion of the redemption  price to be paid
in common shares  divided by the average  market price of one common share.  See
"--Delivery of Shares; Fractional Shares".

    The table below shows redemption prices of a Debenture on March 19, 2010, at
each March 14  thereafter  prior to stated  maturity  and at stated  maturity on
March 14,  2023.  These  prices  reflect the issue price plus  accrued  interest
calculated  to each such date.  The  redemption  price of a  Debenture  redeemed
between such dates would include an additional  amount reflecting the additional
interest,  excluding cash interest, accrued since the immediately preceding date
in the table to the actual redemption date.

    In each case,  we will also pay accrued and unpaid cash interest to the date
of redemption.

    If we restate the amount payable at maturity of the Debentures following the
occurrence  of a Tax Event,  the  Debentures  will be redeemable at the restated
principal  amount  plus  accrued  and  unpaid  interest  from  the  date of such
restatement  through the redemption  date.  However,  except as described  under
"--Redemption  of  Debentures  at the Option of Inco" or  "--Redemption  for Tax
Reasons",  in no event may the Debentures be redeemed prior to March 19, 2010 or
such later date as we may determine. See "--Optional Conversion to Full Cash Pay
Debentures Upon a Tax Event".

    If we redeem less than all of the outstanding Debentures,  the trustee shall
select the Debentures to be redeemed in amounts payable at maturity of $1,000 or
integral  multiples of $1,000, or following a Tax Event, the restated  principal
amount of the  Debentures  or  integral  multiples  of such  restated  principal
amount.  In this case, the trustee may select the Debentures by lot, pro rata or
by any other method the trustee considers fair and appropriate.  If a portion of
a holder's Debentures is selected for partial redemption and the holder converts
a portion of such Debentures,  the converted  portion shall be deemed to be from
the portion selected for redemption.


REDEMPTION FOR TAX REASONS

    We may also redeem all but not less than all of the  Debentures  for cash or
common  shares or a  combination  thereof if we have or would  become  obligated
(including on the future enactment of a proposed change) to pay to the holder of
any Debenture  "additional amounts" (which are more than a de minimis amount) as
a result of any change from March 4, 2003  (including any announced  prospective
change)  in the laws or any  regulations  of  Canada or any  Canadian  political
subdivision  or  taxing  authority,  or any  change  from  March  4,  2003 in an
interpretation  or application  of such laws or  regulations by any  legislative
body,  court,  governmental  agency,  taxing  authority or regulatory  authority
(including the enactment of any  legislation and the publication of any judicial
decision or regulatory or administrative  determination)  and if we cannot avoid
these obligations by taking reasonable  measures  available to us. We define the
term "additional amounts" under "--Canadian  Withholding Taxes". This redemption
would be at the issue price plus  accrued  interest  but without  reduction  for
applicable  Canadian  withholding  taxes (except in respect of certain  excluded
holders).  We will give holders not less than 20 business

                                       25



days' nor more than 60 business days' notice of this redemption, except that (i)
we will not give notice of redemption earlier than 60 business days prior to the
earliest date on or from which we would be obligated to pay any such  additional
amounts, and (ii) at the time we give the notice, the circumstances creating our
obligation to pay such additional  amounts remain in effect.  If we elect to pay
the  redemption  price,  in whole or in part,  in common  shares,  the number of
common shares we deliver will be equal to the portion of the redemption price to
be paid in common  shares  divided  by the  average  market  price of one common
share. See "--Delivery of Shares; Fractional Shares".


CHANGE IN CONTROL REQUIRES OFFER TO PURCHASE DEBENTURES

    Upon the  occurrence of a change in control (as defined below) of Inco on or
prior to March  14,  2010,  we will be  required  to offer to  purchase  all the
Debentures  as of  the  date  that  is 35  business  days  after  notice  of the
occurrence of such change in control (a "change in control  purchase date") at a
price  equal to the issue price plus  accrued  interest to the change in control
purchase  date.  We may,  at our  option,  elect to pay the  change  in  control
purchase  price  in  cash or  common  shares  or any  combination  thereof.  See
"--Delivery   of   Shares;    Fractional    Shares",    "Certain    Income   Tax
Considerations--Certain      United      States      Federal      Income     Tax
Considerations--Disposition or Conversion of the Debentures" and "Certain Income
Tax      Considerations--Certain      Canadian      Federal      Income      Tax
Considerations--Ownership of Debentures".

    If prior to a change in control purchase date the amount payable at maturity
of the Debentures has been restated  following the occurrence of a Tax Event, we
will be required to purchase  the  Debentures  at a price equal to the  restated
principal  amount plus accrued  interest from the date of such conversion to the
change in control purchase date.

    Within 15 business days after the occurrence of a change in control,  we are
obligated  to mail to the  trustee  and to all  holders of  Debentures  at their
addresses  shown in the register of the registrar,  and to beneficial  owners as
required by  applicable  law, a notice  regarding  the change in control,  which
notice shall state, among other things:

    o   the events causing a change in control;

    o   the date of such change in control;

    o   the last date on which the change in  control  purchase  notice  must be
        given;

    o   the change in control purchase price;

    o   the change in control purchase date;

    o   whether  we will pay the  change in  control  purchase  price in cash or
        common shares or any combination thereof,  specifying the percentages of
        each;

    o   if we elect to pay in  common  shares,  the  method of  calculating  the
        average market price of common shares;

    o   the name and address of the paying agent;

    o   the conversion rate and any adjustments to the conversion rate;

    o   that  Debentures  with  respect  to which a change in  control  purchase
        notice is given by the  holder  may be  converted  only if the change in
        control  purchase notice has been withdrawn in accordance with the terms
        of the indenture; and

    o   the procedures that holders must follow to exercise these rights.

    To accept the change in control  purchase  offer,  the holder must deliver a
written  change in  control  purchase  notice (a  "change  in  control  purchase
notice")  to the paying  agent  prior to the close of  business on the change in
control  purchase date.  The required  change in control  purchase  notice shall
state:

    o   the certificate numbers of the Debentures to be delivered by the holder;

    o   the  portion  of the amount  payable at  maturity  of  Debentures  to be
        purchased,  which  portion  must be $1,000 or an  integral  multiple  of
        $1,000 (or following a Tax Event,  the restated  principal amount of the
        Debentures or an integral multiple of such restated principal amount);

                                       26



    o   that we are to  purchase  such  Debentures  pursuant  to the  change  in
        control offer; and

    o   in the event that we elect,  pursuant to the notice that we are required
        to give, to pay the change in control  purchase  price in common shares,
        in  whole  or in part,  but the  change  in  control  purchase  price is
        ultimately to be paid to the holder  entirely in cash because any of the
        conditions  to  payment of such price or portion of such price in common
        shares is not satisfied  prior to the close of business on the change in
        control purchase date, as described below, whether the holder elects:

            (1) to withdraw the change in control  purchase notice as to some or
        all of the Debentures to which it relates, or

            (2) to  receive  cash in  respect  of the  entire  change in control
        purchase price for all  Debentures or portions of Debentures  subject to
        such change in control purchase notice.

    If the holder  fails to  indicate  its choice with  respect to the  election
described in the final  bullet  point above,  the holder shall be deemed to have
elected  to  receive  cash in  respect  of the  entire  purchase  price  for all
Debentures   subject  to  the  change  in  control   purchase  notice  in  these
circumstances.

    A holder may withdraw any change in control  purchase notice by delivering a
written  notice of withdrawal to the paying agent prior to the close of business
on the change in control purchase date. The notice of withdrawal shall state:

    o   the amount payable at maturity of the Debentures being withdrawn;

    o   the certificate numbers of the Debentures being withdrawn; and

    o   the amount payable at maturity,  if any, of the  Debentures  that remain
        subject to a change in control purchase notice.

    Payment of the change in control  purchase price for a Debenture for which a
change in control  purchase notice has been delivered and not validly  withdrawn
is  conditioned  upon  delivery  of  the  Debenture,   together  with  necessary
endorsements,  to the paying agent at any time after the delivery of such change
in control purchase notice.  Payment of the change in control purchase price for
such  Debenture  will be made  promptly  following  the  later of the  change in
control purchase date or the time of delivery of such Debenture.

    If the paying agent holds money or  securities  sufficient to pay the change
in control  purchase  price of the  Debenture on the business day  following the
change in control  purchase date in accordance  with the terms of the indenture,
then immediately  after the change in control purchase date, such Debenture will
cease to be outstanding and interest on such Debenture will cease to accrue, and
be deemed to be paid,  whether or not the  Debenture  is delivered to the paying
agent.  Thereafter,  all other rights of the holder shall terminate,  other than
the right to receive the change in control  purchase  price upon delivery of the
Debenture.

    A "change in control"  of Inco will be deemed to have  occurred at such time
as:


    o   any person,  including its affiliates and  associates,  other than Inco,
        its subsidiaries or their employee  benefit plans,  files or is required
        to file a Schedule 13D or Schedule TO (or any successor  schedule,  form
        or report  under the  Exchange  Act),  or a  comparable  report with any
        securities  commission  or  securities  regulatory  authority in Canada,
        disclosing  that such person has become the  beneficial  owner of 50% or
        more of the total number of votes attached to our share capital entitled
        to general  voting rights  (currently  our common shares  (collectively,
        "Voting   Securities")  or  other   securities  into  which  the  Voting
        Securities are reclassified or changed, with certain exceptions; or


    o   there shall be  consummated  any  consolidation,  merger,  amalgamation,
        statutory  arrangement  (involving  a business  combination)  or similar
        transaction  of Inco in which Inco is not the  continuing  or  surviving
        corporation  or pursuant to which the common  shares  would be converted
        into cash,  securities  or other  property,  in each case,  other than a
        consolidation,  merger,  statutory  arrangement  (involving  a  business
        combination) or similar  transaction of Inco in which the holders of the
        Voting Securities  immediately prior to such transaction have,  directly
        or  indirectly,  at  least  a  majority  of  the  voting  shares  of the
        continuing or surviving corporation immediately after such transaction.

    The indenture does not permit our board of directors to waive our obligation
to offer to purchase Debentures upon the occurrence of a change in control.

                                       27



    In connection  with any purchase  offer in the event of a change in control,
we will:

    o   comply  with the  provisions  of Rule  13e-4,  Rule  14e-1 and any other
        tender offer rules under the  Exchange  Act and any Canadian  laws which
        may then be applicable; and

    o   file a Schedule TO or any other  schedule  under the  Exchange Act rules
        which may then be applicable.

    To the extent any time  period set forth in the  indenture  is  inconsistent
with  the  requirements  of the  Exchange  Act  or  Canadian  law  or any  rules
thereunder, we will comply with the provisions of such laws or rules.

    The change in control  purchase  feature  of the  Debentures  may in certain
circumstances  make more  difficult or discourage a takeover of Inco. The change
in control purchase feature,  however, is not the result of our knowledge of any
specific effort:

    o   to accumulate Voting Securities;

    o   to obtain  control  of Inco by means of a merger,  amalgamation,  tender
        offer, solicitation or otherwise; or

    o   part  of a plan  by  management  to  adopt  a  series  of  anti-takeover
        provisions.

    Instead, the change in control purchase feature is a standard term contained
in other  offerings  that have been  marketed by the initial  purchasers  of the
Debentures.  The terms of the change in control  purchase  feature resulted from
negotiations between the initial purchasers and us.

    We could, in the future, enter into certain transactions,  including certain
recapitalizations, that would not constitute a change in control with respect to
the change in control purchase feature of the Debentures but that would increase
the amount of our outstanding indebtedness.

    Our ability to purchase  Debentures  upon a change in control may be limited
by the terms of our then existing credit agreements.

    No Debentures  may be purchased for cash or a combination of cash and common
shares by Inco  pursuant  to a change  in  control  purchase  offer if there has
occurred and is continuing  an Event of Default with respect to the  Debentures,
other than a default in the payment of the change in control purchase price with
respect to the Debentures.


DELIVERY OF SHARES; FRACTIONAL SHARES

DELIVERY OF SHARES

    We may,  at our option,  elect to pay the amount  payable at maturity of the
Debentures  in cash or  common  shares  or any  combination  of cash and  common
shares. We may also, at our option,  elect to pay the redemption price or change
in control  purchase price in cash or common shares or any combination  thereof,
or  deliver  cash in lieu of some  or all of the  common  shares  issuable  upon
conversion.  Our right to issue common shares in these  circumstances is subject
to our satisfying various conditions, including:

    o   listing of the common shares on the principal  United States or Canadian
        securities  exchange  on which our common  shares are then listed or, if
        not so listed, on Nasdaq;

    o   the  registration  of the common shares under the Securities Act and the
        Exchange Act, if required; and

    o   any necessary  qualification  or  registration  under  applicable  state
        securities   laws  or  the   availability  of  an  exemption  from  such
        qualification and registration.

    If these  conditions  are not  satisfied  with respect to a holder prior the
close of business on the  applicable  payment  date,  we will make the  required
payment on the Debentures of the holder  entirely in cash. We may not change the
form of components or percentages of components of  consideration to be paid for
the  Debentures  once we have given the notice  that we are  required to give to
holders of Debentures, except as described in the preceding sentence.

    If we elect to satisfy any payment at stated maturity, the redemption price,
or the change in control purchase price of the Debentures in common shares,  the
number of common shares to be delivered by us will be equal to the amount of the
payment

                                       28



to be made in common  shares  divided by the average  market price of one common
share.

    For any  payment  in  respect of the  Debentures,  including  payment of the
Debentures at stated  maturity,  the "average market price" means the average of
the  closing  sale prices of the common  shares for the five  trading day period
ending on the third business day prior to the applicable redemption, conversion,
purchase,  maturity  or  record  date (if the  third  business  day prior to the
applicable redemption, purchase, maturity or record date is a trading day, or if
not, then on the last trading day prior thereto), appropriately adjusted to take
into account the occurrence,  during the period  commencing on the first of such
trading days during such five trading day period and ending on such  redemption,
purchase,  maturity or record  date,  of certain  events that would result in an
adjustment of the conversion rate with respect to the common shares.

    If we elect to satisfy any payment of the amount  payable at  maturity,  the
redemption  price, or the change in control  purchase price of the Debentures in
common  shares,  we will give you notice at least 20  business  days  before the
payment date. Our notice will state:

    o   whether  we will  make  the  payment  in cash or  common  shares  or any
        combination thereof;

    o   if both cash and  common  shares are  payable,  the  percentage  of each
        applicable on a per Debenture basis; and

    o   the method of calculating the average market price of the common shares.

    When we determine the actual number of common shares in accordance  with the
foregoing provisions, we will publish the information on our web site or through
such other public medium as we may use at that time.

    Because the average market price of the common shares is determined prior to
the  applicable  payment date,  holders of Debentures  bear the market risk with
respect  to the value of the  common  shares to be  received  from the date such
average  market price is determined to such payment date. We may deliver  common
shares as payment for the amount payable at maturity,  the  redemption  price or
the change in control  purchase price of the Debentures  only if the information
necessary  to  calculate  the  average  market  price  is  published  daily in a
newspaper of U.S.  national  circulation or on our website or through such other
public medium as we may use at that time.

FRACTIONAL SHARES

    We will not issue any fractional  common shares.  Instead,  we will pay cash
based on the average market price on the  applicable  payment date or conversion
date for any fractional  common shares we would otherwise  deliver on account of
the Debentures.


CERTAIN COVENANTS

    "Attributable  Debt" means as to any particular lease under which any person
is liable at the time as lessee,  and at any date as of which the amount thereof
is to be  determined,  the total net amount of rent  required to be paid by such
person under such lease during the remaining term thereof  (including any period
for which such lease has been  extended or may, at the option of the lessor,  be
extended),  discounted  from the  respective due dates thereof to such date at a
rate per annum  equivalent to the rate inherent in such lease (as  determined in
good faith by Inco) compounded  semi-annually,  excluding amounts required to be

including,  in certain  circumstances,  any termination penalty in the case of a
lease terminable by the lessee.

the indenture or thereafter  acquired or  constructed  by Inco or any Restricted
Subsidiary,  which is located in Canada or the United States or its  territories
or  possessions,  the  gross  book  value  (without  deduction  of  any  reserve
depreciation) of which, in each case, on the date as of which the  determination
is being made,  is an amount which exceeds  0.25% of  Consolidated  Net Tangible
Assets,  except any such plant,  building,  structure or facility or any portion
thereof (together with the land upon which it is erected and fixtures comprising
a part  thereof)  (a)  acquired or  constructed  principally  for the purpose of
controlling or abating atmospheric pollutants or contaminants,  or water, noise,
odor or other  pollution  or (b)  which  our board of  directors  by  resolution
declares is not of material  importance to the total business  conducted by Inco

business outside Canada and the United States or its territories or possessions.

    "Subsidiary" of Inco means any corporation  more than 50% of the outstanding
voting stock of which is owned,  directly or  indirectly,  by Inco and/or one or
more Subsidiaries of Inco.


NEGATIVE PLEDGE

    We have  covenanted  under the indenture  that we will not, and that we will
not permit any Restricted  Subsidiary to, create,  incur or assume any mortgage,
hypothecation,   charge,  pledge,  lien  or  other  security  interest  (each  a
"mortgage") securing any indebtedness for money borrowed  ("Indebtedness") of or
upon any  Principal  Property,  or on  shares  of stock or  indebtedness  of any
Restricted  Subsidiary,  now owned or hereafter acquired by Inco or a Restricted
Subsidiary,  without making effective  provision for the outstanding  Debentures
(together  with,  if and  to  the  extent  we  shall  so  determine,  any  other
indebtedness  or other  obligations  then existing or thereafter  created) to be
secured by such  mortgage  equally  and  ratably  with (or prior to) any and all
indebtedness and obligations secured or to be secured thereby and for so long as
such  Indebtedness  is so  secured.  Such  negative  pledge in general  will not
prevent or  restrict  the  creation,  incurrence  or  assumption  by Inco or any
Restricted Subsidiary of:

    o   any  mortgage  on  property,  shares  of  stock or  Indebtedness  of any
        corporation  existing at the time such corporation  becomes a Restricted
        Subsidiary;

    o   any  mortgage  on  any  Principal  Property  existing  at  the  time  of
        acquisition  of  such  Principal   Property  by  Inco  or  a  Restricted
        Subsidiary,   whether  or  not  assumed  by  Inco  or  such   Restricted
        Subsidiary,  provided  that no such  mortgage  shall extend to any other
        Principal Property of Inco or any Restricted Subsidiary;

    o   any mortgage on any Principal Property (including any improvements on an
        existing Principal  Property)  hereafter acquired or constructed by Inco
        or any Restricted Subsidiary to secure the payment of all or any part of
        the purchase price or cost of  construction  of such Principal  Property
        (or  to  secure  any  Indebtedness  incurred  by  Inco  or a  Restricted
        Subsidiary  for the purpose of financing all or any part of the purchase
        price  thereof  or  cost  of  construction  thereof  or of  improvements
        thereon) created prior to, at the time or within 90 days after the later
        of the acquisition,  completion of construction, or commencement of full
        operation of such  Principal  Property,  provided  that no such mortgage
        shall  extend to any other  Principal  Property of Inco or a  Restricted
        Subsidiary  other  than,  in  the  case  of  any  such  construction  or
        improvement,  any  theretofore  unimproved  real  property  on which the
        Principal Property so constructed, or the improvement, is located;

    o   any mortgage on any Principal  Property or any Restricted  Subsidiary to
        secure  Indebtedness  owing  by it to  Inco  or  to  another  Restricted
        Subsidiary;

    o   any  mortgage  on any  Principal  Property  of  Inco  or any  Restricted
        Subsidiary  in favor of any  government  authority  in  Canada or in the
        United States to secure partial,  progress, advance or other payments to
        Inco or any  Restricted  Subsidiary  pursuant to the  provisions  of any
        contract or statute;

    o   any  mortgage  on any  Principal  Property  of  Inco  or any  Restricted
        Subsidiary existing on the date of the indenture;

    o   any  mortgage  on any  Principal  Property  of  Inco  or any  Restricted
        Subsidiary  created for the sole purpose of renewing or refunding any of
        the foregoing mortgages,  provided that the Indebtedness secured thereby
        shall not exceed the

                                       30



        principal  amount of Indebtedness so secured at the time of such renewal
        or  refunding,  and that such  renewal or  refunding  mortgage  shall be
        limited to all or any part of the same property and improvements thereon
        which secured the mortgage renewed or refunded; or

    o   any mortgage on any Principal  Property created,  incurred or assumed to
        secure  Indebtedness of Inco or any Restricted  Subsidiary,  which would
        otherwise  be subject to the  foregoing  restrictions,  in an  aggregate
        amount  which,  together with the  aggregate  principal  amount of other
        Indebtedness   secured  by  mortgages  on  Principal   Properties   then
        outstanding (excluding Indebtedness secured by mortgages permitted under
        the foregoing  exceptions) and the  Attributable  Debt in respect of all
        Sale and  Leaseback  Transactions  entered  into  after  the date of the
        indenture (not including  Attributable  Debt in respect of any such sale
        and  Leaseback  Transactions  the  proceeds  of which are applied as set
        forth below under  "--Limitation  on Sale and  Leaseback  Transactions")
        would not then exceed 5% of Consolidated Net Tangible Assets.

    The  following  types of  transactions  will not be deemed  to be  mortgages
securing  Indebtedness:  any acquisition by Inco or any Restricted Subsidiary of
any property or assets subject to any  reservation or exception  under the terms
of which any  vendor,  lessor or  assignor  creates,  reserves or excepts or has
created,  reserved or excepted an interest in nickel, copper,  cobalt,  precious
metals,  oil,  gas or any  other  mineral  or  timber  in place or the  proceeds
thereof; any conveyance or assignment whereby Inco or any Restricted  Subsidiary
conveys or assigns to any  person or  persons  an  interest  in nickel,  copper,
cobalt, precious metals, oil, gas or any other mineral or timber in place or the
proceeds thereof; or any mortgage upon any property or assets owned or leased by
Inco or any Restricted  Subsidiary or in which Inco or any Restricted Subsidiary
owns an  interest  to secure to the person or persons  paying  the  expenses  of
developing or conducting operations for the recovery, storage, transportation or
sale of the mineral resources of the said property (or property with which it is
utilized)  the  payment to such  person or  persons of Inco's or the  Restricted
Subsidiary's proportionate part of such development or operating expense.


LIMITATION ON SALE AND LEASEBACK TRANSACTIONS

    Sale and Leaseback  Transactions (which term is defined in the indenture and
which definition excludes certain temporary leases and leases between Inco and a
Restricted  Subsidiary  or  between  Restricted  Subsidiaries)  by  Inco  or any
Restricted  Subsidiary of any Principal Property are prohibited by the indenture
unless: (1) immediately prior to the entering into of such arrangement,  Inco or
such Restricted  Subsidiary  could create a mortgage on such Principal  Property
securing  Indebtedness in an amount equal to the Attributable  Debt with respect
to the particular Sale and Leaseback  Transaction;  or (2) within 120 days after
the sale or transfer,  an amount equal to the fair market value of the Principal
Property  so sold and  leased  back at the time of  entering  into such Sale and
Leaseback  Transaction  (as  determined by our board of directors) is applied to
the  prepayment  (other than  mandatory  prepayment) of Funded Debt of Inco or a
Restricted  Subsidiary  (other  than  Funded  Debt  held by the  Company  or any
Restricted Subsidiary).


AMALGAMATION AND MERGER

    We have  covenanted  in the  indenture  that  we will  not  enter  into  any
consolidation,  amalgamation  or merger with or into any other  corporation,  or
statutory  arrangement in which Inco  participates,  or any sale,  conveyance or
lease of all or substantially  all of our property unless (1) immediately  after
such  consolidation,   amalgamation,   merger,   statutory  arrangement,   sale,
conveyance or lease the  corporation  (whether  Inco or such other  corporation)
formed by or surviving any such  consolidation,  amalgamation  or merger,  or to
which  such sale,  conveyance  or lease  shall  have been made,  shall not be in
default in the  performance  or  observance  of any of the terms,  covenants and
conditions  of the  indenture to be kept or  performed by Inco;  (2) the due and
punctual payment of the principal of and interest on the Debentures, and the due
and punctual  performance  and observance of all of the covenants and conditions
of the  indenture  to be  performed  or  observed  by Inco and,  for which  each
security by its terms provided for conversion, shall have provided for the right
to convert  such  security  in  accordance  with its terms,  shall be  expressly
assumed,  by a  supplemental  indenture  satisfactory  in form  to the  trustee,
executed and delivered to the trustee,  by the  corporation (if other than Inco)
formed by or surviving any such consolidation, amalgamation, merger or statutory
arrangement  or into which Inco shall have been  merged,  or by the  corporation
which shall have  acquired or leased such  property  and (3) if the  corporation
(whether  Inco  or  another   corporation)  formed  by  or  surviving  any  such
consolidation,  amalgamation,  merger or statutory arrangement, or to which such
sale,  conveyance or lease will have been made, is organized under the laws of a
jurisdiction other than Canada or the United States or any province,  territory,
state or district thereof (each, a "relevant taxing jurisdiction"), we become or
such  successor  corporation  becomes  obligated  by  a  supplemental  indenture
satisfactory  in form to the  trustee  to make all  payments  on  account of the
Debentures without withholding of a deduction for, or on account of, any present
or future taxes or governmental charges ("specified taxes") imposed or levied by
a  relevant  taxing  jurisdiction,   unless  we  are  required  by  law  or  the
interpretation  or  administration  thereof to withhold or deduct such specified
taxes. In that event, we will pay as additional interest such additional amounts
("other  additional  amounts") as may be

                                       31



necessary  in order that the net amounts  received by each holder of  Debentures
after such withholding or deduction, including any withholding or deduction with
respect to such other additional amounts,  shall equal the respective amounts of
principal  and  interest  which  would  have been  receivable  in respect of the
Debentures in the absence of such withholding or deduction,  except that no such
other  additional  amounts  shall be payable with respect to payments  made to a
holder:

        (a) if such  holder is liable for such taxes by reason of such holder or
    the beneficial  owner of the Debenture  having a present or former direct or
    indirect  connection  with the relevant taxing  jurisdiction  other than the
    mere holding of the debenture or the receipt of payment in respect thereof;

        (b) for any taxes  imposed as a result of the  failure of such holder or
    beneficial owner to comply with certification,  identification,  declaration
    or similar reporting requirements, if such compliance is required by statute
    or by  regulation,  administrative  practice or an applicable  treaty,  as a
    precondition to relief or exemption from such tax;

        (c)  for  any  estate,  inheritance,  gift,  sales,  transfer,  personal
    property or similar  tax,  duty or fine,  assessment  or other  governmental
    charge;

        (d) for any tax  which  is  payable  otherwise  than by  withholding  or
    deduction from payment by us of principal of, or interest on, the debenture;

        (e)  if the  payment  of  other  additional  amounts  would  be for  any
    withholding  or  deduction  imposed on a payment to an  individual  which is
    required to be made pursuant to a European  Union  directive on the taxation
    of  savings  implementing  the  conclusions  of ECOFIN  Council  meeting  of
    November 26-27, 2000 or any law implementing or complying with or introduced
    in order to conform to such directive; or

        (f) any combination of items (a) to (e);

nor will such other additional  amounts be paid with respect to a payment on the
Debenture to a holder who is a fiduciary or  partnership  or other than the sole
beneficial  owner of such  Debenture to the extent that a beneficiary or settlor
with respect to such fiduciary,  or a member of such partnership or a beneficial
owner  thereof,  would not have been entitled to receive a payment of such other
additional  amounts had such  beneficiary,  settlor,  member or beneficial owner
received directly its beneficial or distributive share of such payment.

    We shall have the right  reasonably  to require a holder as a  condition  of
payment  of  amounts  on the  Debentures  to  present  at such place as we shall
reasonably  designate  a  certificate  in such  form as we may from time to time
prescribe to enable us to determine our duties and  liabilities  with respect to
(i) any  specified  taxes that we or any  withholding  agent may be  required to
deduct or withhold from payments in respect of a Debenture  under any present or
future law of any relevant  taxing  jurisdiction or any regulation of any taxing
authority thereof and (ii) any reporting or other  requirements  under such laws
or  regulations.  To the extent not otherwise  prohibited by applicable laws and
regulations,  we shall be entitled to determine our duties and liabilities  with
respect to such deduction,  withholding,  reporting or other requirements on the
basis of information contained in such certificate,  or, if no certificate shall
be  presented,  on the  basis  of any  presumption  created  by any  such law or
regulation, and shall be entitled to act in accordance with such determination.

    If,  upon  any  such  consolidation,   amalgamation,   merger  or  statutory
arrangement  or  upon  any  such  sale,   conveyance  or  lease,   or  upon  any
consolidation,  amalgamation,  merger or statutory arrangement of any Restricted
Subsidiary,  or upon the sale,  conveyance or lease of all or substantially  all
the  property  of any  Restricted  Subsidiary  to  any  other  corporation,  any
Principal  Property  of Inco or of any  Restricted  Subsidiary  or any shares of
stock or indebtedness of any Restricted Subsidiary owned by Inco or a Restricted
Subsidiary  immediately prior thereto or immediately  thereafter would thereupon
become subject to any mortgage securing any  Indebtedness,  unless assumption of
such  mortgage  would be  permitted  under the  covenant  described  above under
"--Negative Pledge" without securing the outstanding Debentures,  Inco, prior to
such  consolidation,   amalgamation,   merger,   statutory  arrangement,   sale,
conveyance  or  lease,  will  secure  or cause  to be  secured  by  supplemental
indenture,  the due and punctual  payment of the principal of and  interest,  if
any,  on the  Debentures  (together  with,  if and to the  extent  Inco shall so
determine,   any  other  indebtedness  or  other  obligation  then  existing  or
thereafter  created) by a direct mortgage equally and ratably with (or prior to)
any and all indebtedness and obligations secured or to be secured thereby and so
long as such indebtedness is so secured.


                                       32



DEFAULT AND RELATED MATTERS

EVENTS OF DEFAULT

    You will have special rights if an Event of Default occurs and is not cured,
as described later in this subsection.

    The term "Event of Default" means any of the following:

    o   we do not pay or deliver (in cash or common shares,  as applicable)  the
        amount  payable at maturity (or if the amount payable at maturity of the
        Debentures  has  been  restated  following  a Tax  Event,  the  restated
        principal  amount),  the redemption price,  conversion  consideration or
        change in control purchase price with respect to any Debenture when such
        becomes due and payable;

    o   if we fail to pay interest  when due and such failure  continues  for 30
        days;

    o   we remain in breach of a  restrictive  covenant or any other term of the
        indenture  for 90 days after we  receive a notice of default  stating we
        are in  breach.  The notice  must be sent by either  the  trustee or the
        holders  of at  least  25% of the  amount  payable  at  maturity  of the
        Debentures;

    o   our  obligation  to repay any  outstanding  debt is  accelerated  by our
        lenders,  and this repayment  obligation remains accelerated for 10 days
        after we receive a notice of default as described in the second sentence
        of the previous bullet; or

    o   we file for  bankruptcy in Canada or certain other events in bankruptcy,
        insolvency or reorganization occur.

REMEDIES IF AN EVENT OF DEFAULT OCCURS

    If an Event of Default has occurred  and has not been cured,  the trustee or
the holders of at least 25% in amount  payable at maturity of the Debentures may
declare  the issue  price plus  accrued  interest  and  accrued  and unpaid cash
interest on the Debentures to be due and immediately  payable.  This is called a
declaration of acceleration  of maturity.  If an Event of Default occurs because
of certain events in bankruptcy,  insolvency or reorganization,  the issue price
plus  accrued  interest on the  Debentures  will be  automatically  accelerated,
without any action by the trustee or any holder.  A declaration of  acceleration
of  maturity  may be  cancelled  by the holders of at least a majority in amount
payable at maturity of the Debentures.

    Except in cases of default,  where the trustee has some special duties,  the
trustee is not required to take any action under the indenture at the request of
any  Debentures   holders  unless  the  holders  offer  the  trustee  reasonable
protection from expenses and liability  (called an  "indemnity").  If reasonable
indemnity is provided,  the holders of a majority in amount  payable at maturity
of the  outstanding  Debentures  may  direct  the  time,  method  and  place  of
conducting any lawsuit or other formal legal action seeking any remedy available
to the trustee. These majority holders may also direct the trustee in performing
any other action under the indenture.

    Before you bypass the  trustee  and bring your own  lawsuit or other  formal
legal  action  or take  other  steps to  enforce  your  rights or  protect  your
interests relating to the Debentures, the following must occur:

    o   you must give the  trustee  written  notice that an Event of Default has
        occurred and remains uncured;

    o   the  holders  of at least  25% in  amount  payable  at  maturity  of all
        outstanding Debentures must make a written request that the trustee take
        action because of the default,  and must offer  reasonable  indemnity to
        the  trustee  against  the cost and other  liabilities  of  taking  that
        action;

    o   the trustee must have not taken action for 60 days after  receipt of the
        above notice and offer of indemnity; and

    o   the trustee has not received  inconsistent  directions from holders of a
        majority in amount payable at maturity during such 60-day period.

    However,  you are entitled at any time to bring a lawsuit for the payment of
money due on your Debenture on or after its due date.

    We will furnish to the trustee every year a written  statement of certain of
our officers  certifying  that to their  knowledge

                                       33



we are in compliance with the indenture and the  Debentures,  or else specifying
any default.


OPTIONAL CONVERSION TO FULL CASH PAY DEBENTURES UPON A TAX EVENT

    From and after the date of the occurrence of a Tax Event (as defined below),
we shall have the option to elect to have semi-annual  coupon interest accrue at
1.5% per year on a  principal  amount per  Debenture  (the  "restated  principal
amount")  equal to the issue price plus accrued  interest to the date of the Tax
Event or the date on which we exercise the option  described herein whichever is
later (the "option exercise date").

    Semi-annual  coupon  interest shall accrue from the option exercise date and
shall be payable in cash semi-annually on the interest payment dates of March 14
and  September  14 of each year to holders of record at the close of business on
March 1 or September 1 immediately preceding the interest payment date. Interest
will be computed on a  semi-annual  bond  equivalent  basis using a 360-day year
comprised of twelve  30-day  months.  Interest  will accrue from the most recent
date on which  interest has been paid  subsequent  to our exercise of the option
or, if no interest had been paid subsequent to our exercise of the option,  from
the restatement date.

    A  "Tax  Event"  means  that  Inco  shall  have  received  an  opinion  from
independent  tax counsel  experienced  in such matters to the effect that, on or
after March 4, 2003, as a result of:

    o   any amendment to, or change (including any announced prospective change)
        in, the laws (or any  regulations  thereunder)  of the United  States or
        Canada or any  political  subdivision  or taxing  authority  thereof  or
        therein; or

    o   any amendment to, or change in, an interpretation or application of such
        laws or regulations by any legislative body, court,  governmental agency
        or regulatory  authority (including the enactment of any legislation and
        the publication of any judicial decision or regulatory determination),

in each case in which  amendment  or change is enacted,  promulgated,  issued or
announced  or which  interpretation  is issued or  announced  or which action is
taken, on or after March 4, 2003, there is more than an insubstantial  risk that
interest payable on the Debentures either:

    o   where it is now  deductible  on a current  accrual  basis,  would not be
        deductible on a current accrual basis, or

    o   would not be deductible under any other method,

in  either  case,  in  whole  or in  part,  by  Inco  (by  reason  of  deferral,
disallowance, or otherwise) for Canadian income tax purposes.

    The  modification  of the  terms  of  Debentures  by us upon a Tax  Event as
described above could possibly alter the timing of income recognition by holders
of the Debentures  with respect to the  semi-annual  payments of interest due on
the  Debentures  after  the  option  exercise  date.  See  "Certain  Income  Tax
Considerations--Certain United States Federal Income Tax Considerations".


CANADIAN WITHHOLDING TAXES

    We will make payments on account of the  Debentures  without  withholding or
deducting on account of any present or future  Canadian tax or other  government
charge ("Canadian  taxes"),  unless we are required by law or the interpretation
or  administration  thereof,  to withhold or deduct  Canadian  taxes.  If we are
required to withhold or deduct any amount on account of Canadian  taxes, we will
make such withholding or deduction and pay as additional interest the additional
amounts ("additional amounts") necessary so that the net amount received by each
holder of Debentures after the withholding or deduction  (including with respect
to  additional  amounts)  will not be less than the amount the holder would have
received if the Canadian  taxes had not been withheld or deducted.  We will make
similar  payment of  additional  amounts to holders of  Debentures  (other  than
excluded  holders) that are exempt from  withholding but are required to pay tax
directly on amounts  otherwise  subject to withholding.  However,  no additional
amounts will be payable  with respect to a payment made to holders  (referred to
as "excluded  holders")  subject to Canadian tax on those payments  because they
carry on  business  in  Canada,  or who fail to comply  with any  administrative
requirements  necessary as a precondition to exemption from withholding Canadian
taxes, or to certain other excluded holders,  as described in the indenture.  We
will  remit  the  amount  we  withhold  or  deduct  to the  relevant  authority.
Additional amounts will be paid in cash, as applicable,  at stated maturity,  on
any  redemption  date,  on a conversion  date,  on any  purchase  date or on any
semi-annual interest payment date.


                                       34



MODIFICATION AND WAIVER

    There  are  three  types of  changes  we can make to the  indenture  and the
Debentures.

    Changes  Requiring  Your Approval.  First,  there are changes that cannot be
made to your Debentures without your specific approval.  The following is a list
of those types of changes:

    o   alter the manner or rate of accrual of interest on any Debenture;

    o   change the stated maturity of the principal on any Debenture;

    o   reduce any amount payable upon conversion (except as provided for in the
        indenture),  redemption,  holder redemption, or purchase of a Debenture,
        including any additional amounts;

    o   make any Debenture payable in money or securities other than that stated
        in the indenture;

    o   make any  change  that  adversely  affects  our  obligation  to offer to
        purchase, or to purchase, a Debenture;

    o   adversely affect the right to convert any Debenture (except as permitted
        by the indenture);

    o   change the place or currency of payment on a Debenture;

    o   impair your right to sue for payment or conversion;

    o   reduce the  percentage of holders of Debentures  whose consent is needed
        to modify or amend the indenture;

    o   reduce the  percentage of holders of Debentures  whose consent is needed
        to waive compliance with certain provisions of the indenture or to waive
        certain defaults; or

    o   modify any other aspect of the provisions  dealing with modification and
        waiver of the indenture.

    Changes  Requiring a  Super-Majority  Vote. The second type of change to the
indenture  and the  Debentures  is the  kind  that  requires  a vote in favor by
holders of  Debentures  owning 66 2/3% of the amount  payable at maturity of the
Debentures.  Most changes fall into this category, except for clarifying changes
and  certain  other  changes  that  would not  adversely  affect  holders of the
Debentures.  The same vote would be required for us to obtain a waiver of all or
part of the restrictive  covenants described in the indenture,  or a waiver of a
past default.  However,  we cannot  obtain a waiver of a payment  default or any
other aspect of the  indenture or the  Debentures  listed in the first  category
described  previously  under "Changes  Requiring Your Approval" unless we obtain
your individual consent to the waiver.

    Changes Not  Requiring  Approval.  The third type of change does not require
any vote by holders of Debentures.  This type is limited to  clarifications  and
certain other changes that would not adversely affect holders of the Debentures.

    Further  Details  Concerning  Voting.  When  taking a vote,  we will use the
amount that would be due and  payable on the voting date if the stated  maturity
of the Debentures were accelerated to that date because of a default.

    Your Debentures are not considered "outstanding",  and therefore will not be
eligible to vote,  if we have  deposited  or set aside in trust for you money or
securities for their payment or redemption.

    We will  generally  be  entitled  to set any day as a  record  date  for the
purpose of determining  the holders of outstanding  Debentures that are entitled
to vote or take other action under the indenture.  If we set a record date for a
vote or other  action to be taken by  holders,  that vote or action may be taken
only by persons who are holders of outstanding Debentures on the record date.


--------------------------------------------------------------------------------
"STREET NAME" AND OTHER  INDIRECT  HOLDERS SHOULD CONSULT THEIR BANKS OR BROKERS
FOR  INFORMATION  ON HOW  APPROVAL MAY BE GRANTED OR DENIED IF WE SEEK TO CHANGE
THE INDENTURE OR THE DEBENTURES OR REQUEST A WAIVER.

                                       35



GOVERNING LAW

    The  indenture  and  the  Debentures  are  governed  by,  and  construed  in
accordance with, the laws of the State of New York.


CONSENT TO SERVICE

    In  connection  with the  indenture,  we have  designated  and  appointed CT
Corporation  System as our authorized  agent upon which process may be served in
any suit or  proceeding  arising  out of or  relating  to the  indenture  or the
Debentures that may be instituted in any federal or New York state court located
in the Borough of Manhattan,  in the City of New York, or brought by the trustee
(whether  in its  individual  capacity or in its  capacity as trustee  under the
indenture),  and we irrevocably submit to the non-exclusive jurisdiction of such
courts.


ENFORCEABILITY OF JUDGMENTS

    Since  substantially all of our assets, as well as the assets of most of our
directors  and officers,  are located  outside the United  States,  any judgment
obtained  in the  United  States  against  us or  certain  of our  directors  or
officers,  including  judgments  with respect to the payment of principal on the
Debentures, may not be collectible within the United States.

    We have been informed by Osler, Hoskin & Harcourt LLP, our Canadian counsel,
that  the  laws of the  Province  of  Ontario  and the  federal  laws of  Canada
applicable  therein  permit  an  action to be  brought  in a court of  competent
jurisdiction in the Province of Ontario on any final and conclusive  judgment in
personam of any federal or state court  located in the State of New York (a "New
York Court")  against Inco,  which judgment is subsisting and  unsatisfied for a
sum certain with respect to the  enforcement of the indenture and the Debentures
that is not impeachable as void or voidable under the internal laws of the State
of New York if (1) the New York Court  rendering such judgment had  jurisdiction
over the judgment debtor, as recognized by the courts of the Province of Ontario
(and  submission  by Inco in the indenture to the  jurisdiction  of the New York
Court will be sufficient for that  purpose);  (2) such judgment was not obtained
by fraud or in a manner contrary to natural justice and the enforcement  thereof
would not be inconsistent with public policy, as such terms are understood under
the laws of the  Province  of  Ontario,  or  contrary  to any order  made by the
Attorney  General of Canada  under the  Foreign  Extraterritorial  Measures  Act
(Canada); (3) the enforcement of such judgment would not be contrary to the laws
of general  application  limiting the enforcement of creditors'  rights and does
not  constitute,  directly or indirectly,  the  enforcement of foreign  revenue,
expropriatory  or penal laws in the Province of Ontario;  (4) no new  admissible
evidence relevant to the action is discovered prior to the rendering of judgment
by the court in the Province of Ontario;  (5) interest payable on the Debentures
is not  characterized  by a court in the Province of Ontario as interest payable
at a criminal  rate  within the  meaning of  Section  347 of the  Criminal  Code
(Canada);  and (6) the action to enforce such  judgment is commenced  within the
appropriate  limitation period; except that any court in the Province of Ontario
may only give  judgment in  Canadian  dollars.  In the opinion of such  counsel,
there are no reasons  under present laws of the Province of Ontario for avoiding
recognition of such a judgment of a New York Court under the indenture or on the
Debentures based upon public policy.


DISCHARGE OF THE INDENTURE

    We may  satisfy  and  discharge  our  obligations  under  the  indenture  by
delivering  to the trustee for  cancellation  all  outstanding  Debentures or by
depositing  with the  trustee,  the paying  agent or the  conversion  agent,  if
applicable,  after the Debentures have become due and payable, whether at stated
maturity,  on any  redemption  date, a change in control  purchase date, or upon
conversion or otherwise,  cash or common shares, or any combination  thereof (as
applicable  under  the  terms  of the  indenture)  sufficient  to pay all of the
outstanding  Debentures and paying all other sums payable under the indenture by
us.


LIMITATIONS OF CLAIMS IN BANKRUPTCY

    If a bankruptcy proceeding is commenced in respect of Inco under Title 11 of
the United States Code, the claim of the holder of a Debenture may be limited to
the issue price of the  Debenture  plus accrued  interest from the issue date to
the commencement of the proceeding.

    If an  assignment  is filed or a receiving  order  issued in respect of Inco
under the Bankruptcy and Insolvency Act (Canada) or a proceeding is commenced in
respect of Inco under the Winding-Up and Restructuring  Act (Canada),  the claim
of a holder may be limited in accordance  with the terms of the Debenture to the
issue price of the  Debenture  plus accrued  interest from the issue date to the
commencement  of the  proceeding  plus, if funds are available  after paying all
proven  claims in full,  interest  from that date to the date of  payment of the
claim at the rate of 5% per annum.

                                       36



    If a  proposal  is  filed  in  respect  of Inco  under  the  Bankruptcy  and
Insolvency  Act (Canada) or a  proceeding  is commenced in respect of Inco under
the  Companies'  Creditors  Arrangement  Act  (Canada) or under any  bankruptcy,
arrangement, reorganization, dissolution, liquidation, insolvency, winding-up or
similar  law now or  hereafter  in  effect  for  the  relief  from or  otherwise
affecting  creditors of us (other than an  assignment  filed or receiving  order
issued  under  the  Bankruptcy  and  Insolvency  Act  (Canada)  or a  proceeding
commenced under the Winding-Up and Restructuring  Act (Canada)),  the claim of a
holder may be limited in accordance with the terms of the Debenture to the issue
price  of the  Debenture  plus  accrued  interest  from  the  issue  date to the
commencement of such proceeding.


INFORMATION CONCERNING THE TRUSTEE


    We have  appointed  The Bank of New York as the trustee  under the indenture
and as paying agent,  conversion agent,  Debentures  registrar and custodian for
the  Debentures.  The trustee or its  affiliates  may provide  banking and other
services to us in the ordinary  course of their  business.  The Bank of New York
currently  acts as our trustee with respect our existing  indentures,  including
those related to our 7 3/4% Convertible  Debentures due 2016, our 9 7/8% Sinking
Fund Debentures due 2019, our 9.60% Debentures due 2022, our Liquid Yield Option
Notes due 2021, our 7.20% Debentures due 2032, our 7 3/4% Notes due 2012 and our
3 1/2% Subordinated Debentures due 2052.



                                 LEGAL OWNERSHIP


STREET NAME AND OTHER INDIRECT HOLDERS

    Investors who hold Debentures in accounts at banks or brokers will generally
not be recognized by us as legal holders of  Debentures.  This is called holding
in "street name".  Instead,  we would recognize only the bank or broker,  or the
financial  institution  the  bank  or  broker  uses to  hold  Debentures.  These
intermediary  banks,  brokers  and  other  financial   institutions  pass  along
principal,  interest and other payments on Debentures, either because they agree
to do so in their customer  agreements or because they are legally  required to.
If you  hold  Debentures  in  street  name,  you  should  check  with  your  own
institution to find out:

    o   how it handles securities payments, conversions,  redemptions, purchases
        and notices;

    o   whether it imposes fees or charges;

    o   how it would handle voting if ever required;

    o   whether and how you can instruct it to send you Debentures registered in
        your own name so you can be a direct holder in the limited circumstances
        described below; and

    o   how it would pursue  rights under the  Debentures if there was a default
        or other event  triggering  the need for holders to act to protect their
        interests.


DIRECT HOLDERS

    Our obligations,  as well as the obligations of the trustee and those of any
third parties employed by us or the trustee, run only to persons or entities who
are the direct  holders of the  Debentures,  i.e.,  those who are  registered as
holders of the Debentures.  As noted above, we do not have obligations to you if
you hold in street name or through  other  indirect  means,  either  because you
choose to hold the  Debentures  in that  manner or because  the  Debentures  are
issued in the form of global securities as described below. For example, once we
make payment to the registered holder, we have no further responsibility for the
payment even if that registered  holder is legally  required to pass the payment
along to you as a street name customer but does not do so.


GLOBAL SECURITIES

    A  global  security  is a  special  type of  indirectly  held  security,  as
described above under "--Street Name and Other Indirect Holders".

                                       37



    Since the  Debentures  were  issued in the form of  global  securities,  the
ultimate beneficial owners can only be indirect holders.  DTC is the depositary.
The Debentures  included in the global  securities may not be transferred to the
name of any other direct holder unless the special circumstances described below
occur.

    Any person wishing to own a Debenture  included in a global security must do
so  indirectly  by virtue of an account with a broker,  bank or other  financial
institution that in turn has an account with the depositary.


SPECIAL INVESTOR CONSIDERATIONS FOR GLOBAL SECURITIES

    As an indirect holder, an investor's rights relating to a global security is
governed by the account rules of the investor's financial institution and of the
depositary,  as well as general laws relating to securities transfers. We do not
recognize this type of investor as a registered holder of Debentures and instead
deal only with the depositary that holds the global securities.

    As an  investor  in  Debentures  that are issued  only in the form of global
securities,  you should be aware that except in limited circumstances  described
in the indenture:

    o   you cannot get Debentures registered in your own name;

    o   you  cannot  receive  physical  certificates  for your  interest  in the
        Debentures;

    o   you  will be a street  name  holder  and  must  look to your own bank or
        broker for  payments  on the  Debentures  and  protection  of your legal
        rights relating to the Debentures. See "--Street Name and Other Indirect
        Holders";

    o   you  may  not be  able  to  sell  interests  in the  Debentures  to some
        insurance  companies and other  institutions that are required by law to
        own their securities in the form of physical certificates;

    o   the depositary's policies will govern conversions,  payments, transfers,
        exchange  and other  matters  relating  to your  interest  in the global
        securities.  We and the trustee have no responsibility for any aspect of
        the  depositary's  actions or for its records of ownership  interests in
        the global  securities.  We and the trustee  also do not  supervise  the
        depositary in any way.


SPECIAL SITUATIONS WHEN GLOBAL SECURITIES WILL BE TERMINATED

    In a few special  situations  described  later,  the global  securities will
terminate and interests in the global  securities will be exchanged for physical
certificates representing Debentures. After that exchange, the choice of whether
to hold the  Debentures  directly or in street name will be up to you.  You must
consult  your own bank or broker to find out how to have your  interests  in the
Debentures  transferred  to your own name, so that you will be a direct  holder.
The rights of street name investors and direct  holders in the  Debentures  have
been  described  in the sections  entitled,  "--Street  Name and Other  Indirect
Holders" and "--Direct Holders" above.

    The special situations for termination of global securities are:

    o   when the  depositary  notifies  us that it is  unwilling,  unable  or no
        longer qualified to continue as depositary;

    o   when  we  notify  the  trustee  that we wish  to  terminate  the  global
        securities; or

    o   when an Event of Default on the Debentures has occurred and has not been
        cured.

    Defaults are discussed above under "Description of  Debentures--Default  and
Related Matters".



    EXCEPT UNDER THE HEADING "LEGAL  OWNERSHIP",  IN THIS PROSPECTUS "YOU" MEANS
DIRECT  HOLDERS AND NOT STREET  NAME OR OTHER  INDIRECT  HOLDERS OF  DEBENTURES.
INDIRECT HOLDERS SHOULD READ THE PREVIOUS SECTIONS  ENTITLED  "--STREET NAME AND
OTHER  INDIRECT  HOLDERS"  AND  "--SPECIAL  INVESTOR  CONSIDERATIONS  FOR GLOBAL
SECURITIES".

                          DESCRIPTION OF SHARE CAPITAL


    We are  authorized to issue an unlimited  number of common  shares  (without
nominal or par value) and 45,000,000 Preferred Shares, issuable in series, for a
maximum  consideration  of  Cdn.$1,500,000,000   (or  its  equivalent  in  other
currencies)  with such rights,  privileges,  restrictions and conditions of each
series as the board of directors may determine  before the issue thereof.  As of
May 30, 2003, there were issued and outstanding 183,999,545 common shares.

    Effective  May 1, 2003 we redeemed  all of our issued and  outstanding  5.5%
Convertible Redeemable Preferred Shares Series E. We also redeemed, effective on
the same date, all of our outstanding 5 3/4% Convertible Debentures due 2004.



COMMON SHARES


    Our common  shares  have  general  voting  rights;  that is,  each holder is
entitled  to  receive  notice  of, to attend and to vote at, on the basis of one
vote for each  share  held,  all  meetings  of  shareholders  of Inco other than
meetings at which the holders of another  class or series of shares are entitled
to vote  separately.  Subject  to the rights and  priorities  of the  holders of
Preferred  Shares and any other class or series of shares in our  capital  stock
authorized  from time to time and ranking in priority to the common shares,  the
holders of common  shares are entitled to: (i) receive such  dividends as may be
declared  by our  board of  directors  in its  discretion  out of funds  legally
available therefor,  and (ii) in the event of a distribution of our assets among
our shareholders on a liquidation,  dissolution or winding-up, whether voluntary
or involuntary,  or any other  distribution of our assets among our shareholders
for the purpose of winding up our affairs,  receive, in respect of each share so
held,  a pro rata amount of such  assets of Inco  equivalent  to the  proportion
equal to the  common  shares  then  outstanding  divided by the number of common
shares then outstanding.


    The holders of common shares have no  pre-emptive,  redemption or conversion
rights.  The common shares rank junior to all Preferred Shares both as to return
of capital and as to dividends.


PREFERRED SHARES AS A CLASS

ISSUABLE IN SERIES

    Our Preferred Shares are issuable in series,  each series consisting of such
number  of  shares  and  having  such  provisions  attached  thereto  as  may be
determined by our board of directors.


PRIORITY

    The  Preferred  Shares of each series  rank on a parity  with the  Preferred
Shares of every other series,  and prior to the common  shares,  with respect to
the  payment  of  cumulative  dividends  and the  distribution  of  assets  on a
liquidation,  dissolution or winding up of Inco or for the purpose of winding up
our affairs ("liquidation").

CREATION AND ISSUE OF ADDITIONAL PREFERRED SHARES

    Subject to applicable law, we may, without the consent of the holders of the
Preferred Shares as a class, (1) create additional  Preferred Shares, (2) create
Preferred  Shares of  another  class or  classes  ranking  on a parity  with the
Preferred   Shares  with  respect  to  the  payment  of  dividends   and/or  the
distribution  of assets on  liquidation  or (3) increase  any maximum  number of
authorized  shares of any one or more of such other  classes of shares.  If (but
only so long as) any dividends are in arrears on any  outstanding  series of the
Preferred Shares,  we may not, without the consent,  by a simple majority of the
votes cast,  of the holders of the  Preferred  Shares as a class,  (i) issue any
additional  series of the Preferred  Shares,  or (ii) issue Preferred  Shares of
another class ranking on a parity with the Preferred  Shares with respect to the
payment of dividends and/or the distribution of assets on liquidation.

CLASS VOTING RIGHTS

    The holders of the Preferred Shares are not entitled to any voting rights as
a class  except (1) as  provided  above,  (2) as  provided  by law,  or (3) with
respect  to  the  right  to  vote  on  certain   matters  as   described   under
"--Modification" below. When the holders of Preferred Shares vote as a class, or
when two or more series of Preferred  Shares vote  together at a joint  meeting,
each holder has one  one-hundredth  of a vote in respect of each Canadian dollar
(or its  equivalent in a foreign  currency at the date of issuance) of the issue
price of the Preferred Shares he or she holds.

                                       39




    Our  board of  directors  may,  at the time of  creation  of any  series  of
Preferred Shares,  confer voting rights on such series in addition to the voting
rights of the  holders of the  Preferred  Shares as a class.  It is our board of
directors'  current  intention  that, with respect to the creation of any future
series of Preferred  Shares, to the extent that such Preferred Shares would have
general  voting  rights  then such  shares  would not have more than one vote in
respect of each Preferred Share.


MODIFICATION

    The class provisions attaching to the Preferred Shares may be amended at any
time with such approval of the holders of such shares as may then be required by
law, which  currently is approval by at least  two-thirds of the votes cast at a
meeting of such  holders  duly  called for the  purpose and at which a quorum is
present,  or as are required by the rules of any stock  exchange  upon which the
shares of any series of  Preferred  Shares are then  listed.  In  addition,  the
approval by at least two-thirds of the votes cast at a meeting of the holders of
all our shares carrying  general voting rights is currently  required by law for
the amendment of such class provisions.



COMMON SHARE PURCHASE WARRANTS


    We have  approximately  11,000,000 common share purchase warrants issued and
outstanding  as of May 30,  2003.  Each  whole  warrant  entitles  the holder to
purchase one common share at an exercise  price of Cdn.$30.00  (or at the option
of the  holder,  the  equivalent  in U.S.  dollars  based  upon  exchange  rates
prevailing at the time of exercise), subject to certain adjustments,  until 5:00
p.m. (Toronto time) on August 21, 2006. Any warrants not exercised prior to such
time will expire.



SHAREHOLDER RIGHTS PLAN

    On September 14, 1998, our board of directors  adopted a shareholder  rights
plan that took effect on October 3, 1998,  replacing a prior plan.  The plan was
amended in certain  respects by the board of directors in February 1999, and was
ratified and approved by  shareholders at the 1999 Annual and Special Meeting of
Shareholders. It was further amended in certain limited respects and restated by
the board of  directors  in  February  2002 and  reconfirmed,  as so amended and
restated,  by the  shareholders  at the 2002  Annual and Special  Meeting.  This
current plan,  set forth in an amended and restated  rights plan  agreement (the
"Shareholder  Rights Plan  Agreement")  entered  into between us and CIBC Mellon
Trust Company,  as rights agent, is designed to (i) encourage the fair and equal
treatment of  shareholders  in connection  with any take-over offer by providing
them with more time than the minimum  statutory  period during which a take-over
bid must remain open in order to fully consider their options,  and (ii) provide
the board of directors with  additional  time, if  appropriate,  to pursue other
alternatives  to maximize  shareholder  value.  The new plan is in effect  until
October 2008 subject to  reconfirmation  by holders of our Voting Securities (as
defined below) at our annual meeting in the year 2005.


    The  rights  issued  under the new plan  attach to and trade with our common
shares,  and no separate  certificates will be issued unless an event triggering
these rights occurs.  Certificates  evidencing common shares will be legended to
reflect  that they  evidence the rights  until the  Separation  Time (as defined
below).  Holders  of  our 7 3/4%  Convertible  Debentures,  LYONs,  Subordinated
Debentures and Debentures will generally be entitled to receive, upon conversion
of the  relevant  security,  rights in an amount  equal to the  number of common
shares issued upon conversion of such securities.

    The rights will separate from the common shares  ("Separation  Time") and be
transferable,  trade  separately  from the common shares and become  exercisable
only when a person,  including  any party  related  to or acting  jointly  or in
concert  with such  person,  acquires,  or  announces  its  intention to acquire
beneficial  ownership of 20 per cent or more of (1) our then outstanding  Voting
Securities  or (2) its then  outstanding  common  shares  alone,  in either case
without complying with the "permitted bid" provisions of the plan (as summarized
below),  or without  the  approval  of the board of  directors.  Should  such an
acquisition occur, each right would entitle its holder, other than the acquiring
person or persons  related to or acting  jointly or in concert with such person,
to purchase  additional  common  shares of Inco at a 50 per cent discount to the
then current market price. The acquisition by any person (an "Acquiring Person")
of 20 per cent or more of our common shares or Voting Securities,  other than by
way of a permitted bid, is referred to as a "Flip-in-Event".  Any rights held by
an Acquiring Person will become void upon the occurrence of a Flip-in Event.


    A  "permitted  bid" is a bid made to all holders of our  outstanding  Voting
Securities  that is open for at least  60  days.  If,  at the end of such 60 day
period, more than 50 per cent of our then outstanding common shares,  other than
those  securities owned by the party making the bid and certain related persons,
have been  tendered,  such party may take up and pay for the  common  shares but
must extend the bid for a further 10 business  days to allow other  shareholders
to tender. This feature is designed to provide shareholders who had not tendered
to the bid  with  enough  time to  tender  to the bid  once it is  clear  that a
majority of common shares have been tendered to that bid.

                                       40



    We will be  entitled  (1) to waive the  application  of the plan to enable a
particular  take-over  bid to proceed,  in which case the plan will be deemed to
have been  waived  with  respect  to any other  take-over  bid made prior to the
expiry of any bid subject to such waiver and (2) with the prior  approval of the
holders  of Voting  Securities  or  rights,  to redeem  the  rights  for  normal
consideration at any time prior to a Flip-in Event.


                        CERTAIN INCOME TAX CONSIDERATIONS


CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    THIS  SUMMARY IS OF A GENERAL  NATURE  ONLY AND IS NOT  INTENDED  TO BE, AND
SHOULD NOT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY  PARTICULAR  HOLDER OF
DEBENTURES OR INCO COMMON SHARES AND NO  REPRESENTATION  IS MADE WITH RESPECT TO
THE U.S. FEDERAL INCOME TAX CONSEQUENCES TO ANY PARTICULAR HOLDER.  ACCORDINGLY,
PROSPECTIVE  PURCHASERS OF DEBENTURES SHOULD CONSULT THEIR OWN TAX ADVISORS WITH
RESPECT TO THE U.S. FEDERAL INCOME TAX  CONSIDERATIONS  RELEVANT TO THEM, HAVING
REGARD  TO THEIR  PARTICULAR  CIRCUMSTANCES,  AS WELL AS THE  EFFECT OF ANY U.S.
STATE, LOCAL OR NON-U.S. TAX LAWS.

    This section  describes the material U.S. federal income tax consequences to
you if you are a U.S.  holder of  Debentures  and common  shares  into which the
Debentures  may be  converted.  It  applies  to you  only  if you  acquire  your
Debentures in this offering and you hold your  Debentures and common shares into
which those  Debentures  may be  converted  as capital  assets for U.S.  federal
income tax purposes. This section does not apply to you if you are a member of a
special class of holders subject to special rules, including:

    o   a dealer in securities,

    o   a trader in  securities  that elects to use a  mark-to-market  method of
        accounting for your securities holdings,

    o   a financial institution,

    o   a tax-exempt organization,

    o   a life insurance company,

    o   a person liable for alternative minimum tax,

    o   a person that actually or constructively owns 10 per cent or more of our
        voting stock,

    o   a person that holds Debentures or common shares as part of a straddle or
        a hedging or conversion transaction, or

    o   a person whose functional currency is not the dollar.

    This section is based on the Internal  Revenue Code of 1986, as amended (the
"Code"),   its  legislative   history,   existing  and  proposed  U.S.  Treasury
regulations,  published rulings and court decisions, all as currently in effect.
These laws are subject to change, possibly on a retroactive basis.

    You are a U.S. holder if you are a beneficial owner of common shares and you
are:

    o   a citizen or resident of the United States,

    o   a domestic corporation,

    o   an estate whose income is subject to U.S.  federal income tax regardless
        of its source, or

    o   a trust  if a U.S.  court  can  exercise  primary  supervision  over the
        trust's  administration  and one or more U.S.  persons are authorized to
        control all substantial decisions of the trust.

                                       41



PAYMENTS OF INTEREST

    Except as described below with respect to original issue discount,  interest
on a  Debenture  will be  taxable  to you as  ordinary  income at the time it is
received or accrued,  depending on your method of  accounting  for U.S.  federal
income tax purposes.

ORIGINAL ISSUE DISCOUNT

    The Debentures are being issued at a substantial  discount from their amount
payable at  maturity.  For U.S.  federal  income tax  purposes,  the  difference
between the issue price (i.e.,  the initial price at which a substantial  number
of the Debentures are sold to persons other than bond houses, brokers or similar
persons or  organizations  acting in the  capacity  of  underwriters,  placement
agents,  or  wholesalers)  and the stated  amount  payable at  maturity  of each
Debenture  constitutes original issue discount.  You will be required to include
original issue discount in gross income  periodically,  as described below, over
the term of the  Debentures  without regard to the timing of the receipt of cash
or other payments attributable to such income.

    You must include in gross income, for U.S. federal income tax purposes, your
"accrued  original  issue  discount",  which is the sum of the daily portions of
original  issue  discount  with respect to the Debenture for each day during the
taxable year or portion of a taxable year on which you hold the  Debenture.  The
daily portion is determined by allocating to each day of an accrual period a pro
rata portion of an amount equal to the adjusted  issue price of the Debenture at
the  beginning  of the  accrual  period  multiplied  by the  yield  to  maturity
determined on the basis of  compounding  at the close of each accrual period and
adjusted for the length of each  accrual  period of the  Debenture.  The accrual
period of a Debenture  may be of any length and may vary in length over the term
of the  Debenture,  provided that each accrual period is no longer than one year
and each  scheduled  payment of  principal  or interest  occurs at the end of an
accrual  period or on the first day of an accrual  period.  The  adjusted  issue
price of the Debenture at the start of any accrual  period is the issue price of
the Debenture  increased by the accrued  original  issue discount for each prior
accrual  period.  Under these  rules,  you will have to include in gross  income
increasingly  greater  amounts of original  issue  discount  in each  successive
accrual  period.  Any amount  included in income as original issue discount will
increase your tax basis in the Debenture.

    We will be required to furnish annually to the Internal Revenue Service (the
"IRS") and to certain noncorporate  holders information  regarding the amount of
the original issue discount attributable to that year.

    Original  issue  discount  accrued  with  respect  to your  Debentures  will
constitute  income from sources  outside the United  States,  but,  with certain
exceptions,  will be "passive" or "financial  services" income, which is treated
separately from other types of income for purposes of computing the U.S. foreign
tax credit allowable to you as a U.S. holder.

DISPOSITION OR CONVERSION OF THE DEBENTURES


    Except  as  described  below,  upon  the  sale  or  other  disposition  of a
Debenture, a U.S. holder will recognize gain or loss for U.S. federal income tax
purposes in an amount  equal to the  difference  between the dollar value of the
amount  realized  (except to the extent such amount is  attributable  to accrued
interest  income not  previously  included  in income,  which will be taxable as
ordinary  income)  and the U.S.  holder's  adjusted  tax  basis  (determined  in
dollars) in such Debenture.  Such gain or loss will generally be capital gain or
loss and will be long-term  capital gain or loss if your holding  period for the
Debenture  exceeds  one  year.  Such  gain or loss  will be  income or loss from
sources  within  the  United  States  for U.S.  foreign  tax  credit  limitation
purposes.  Long-term  capital  gain  of  a  noncorporate  U.S.  holder  that  is
recognized  before January 1, 2009 is generally subject to a maximum tax rate of
15 per cent.


    If a  Debenture  held by you is  converted  to  common  shares  or cash or a
combination  of common  shares and cash  pursuant  to your  conversion  right or
pursuant  to our or your  optional  redemption  right  or  right  to  convert  a
Debenture  upon a change in control,  you will not recognize any gain or loss to
the extent that you receive common shares in exchange for the Debenture, but you
will  recognize  any  realized  gain to the extent that you receive  cash.  Your
realized  gain  will be  measured  by the  difference  between  the value of the
consideration you receive for the Debenture and your tax basis in the Debenture.
Any gain  recognized  will  generally  be capital  gain,  and will be  long-term
capital  gain if the  tendered  Debenture  has been held for more than one year.
Your tax  basis in any  common  shares  received  in  exchange  for a  Debenture
(including any fractional shares for which cash is received) will be the same as
your tax basis in the  Debenture  tendered to us in  exchange,  decreased by the
amount of any cash  received in exchange for the  Debenture and increased by the
amount of any gain you recognize on the exchange. Your holding period for common
shares  received  in the  exchange  will  include  the  holding  period  for the
Debenture  tendered  to us in the  exchange.  However,  to the  extent  that the
holding  period for common  shares is  attributable  to accrued  original  issue
discount it will commence on the day following the conversion.

    Cash  received  in lieu of a  fractional  common  share upon  conversion  or
redemption  of a Debenture  or upon a tender of a Debenture  to us on a purchase
date  should be treated  as a payment  in  exchange  for the  fractional  share.
Accordingly,  if the

                                       42



common share is a capital asset in your hands,  the receipt of cash in lieu of a
fractional common share should generally result in capital gain or loss, if any,
measured by the difference  between the cash received for the  fractional  share
and your tax basis in the fractional share.

CONSTRUCTIVE DIVIDEND

    If at any time we make a distribution of property to our  shareholders  that
would be taxable to the  shareholders as a dividend for U.S.  federal income tax
purposes and, in accordance with the anti-dilution provisions of the Debentures,
the conversion rate of the Debentures is increased,  such increase may be deemed
to be the payment of a constructive  dividend to holders of the Debentures  that
is taxable to the extent paid out of our  current or  accumulated  earnings  and
profits (as determined for U.S. federal income tax purposes).

DIVIDENDS ON COMMON SHARES


    You will  include in gross  income  the gross  amount of any  dividend  paid
(before  reduction for Canadian  withholding  taxes) by us out of our current or
accumulated  earnings and profits (as  determined  for U.S.  federal  income tax
purposes)  as ordinary  income when you actually or  constructively  receive the
dividend.  Dividends  received by  non-corporate  U.S. holders before January 1,
2009 are generally taxed at a maximum rate of 15 per cent provided that the U.S.
holder  holds  the  shares  for  more  than 60 days  during  the 120 day  period
beginning  60  days  before  the  ex-dividend  date  and  other  holding  period
requirements   are   met.   The   dividend   will  not  be   eligible   for  the
dividends-received  deduction generally allowed to U.S.  corporations in respect
of dividends  received  from other U.S.  corporations.  The amount of a dividend
paid in foreign  currency that you must include in your income as a U.S.  holder
will be the U.S. dollar value of the foreign currency payments made,  determined
at the  spot  conversion  rate  for  that  foreign  currency  on the date of the
dividend  distribution,  and will be  includible  in your income,  regardless of
whether the payment is in fact converted into U.S. dollars.  Generally, any gain
or loss resulting from currency exchange fluctuations during the period from the
date you  include  the  dividend  payment in income to the date you  convert the
payment into U.S.  dollars will be treated as ordinary  income or loss. The gain
or loss  generally  will be income or loss from sources within the United States
for  U.S.  foreign  tax  credit  limitation  purposes.  Special  rules  apply in
determining the foreign tax credit limitation in respect of dividends subject to
the maximum 15 per cent rate. Distributions in excess of current and accumulated
earnings and profits,  as determined for U.S. federal income tax purposes,  will
be  treated as a return of capital to the extent of your tax basis in the common
shares and thereafter as capital gain.


    Subject to certain limitations and the provisions of the next paragraph, the
Canadian tax withheld  and paid over to Canada will be  creditable  against your
U.S.  federal  income tax  liability.  For U.S.  foreign  tax credit  limitation
purposes,  the dividend will be income from sources  without the United  States,
but generally will be treated separately,  together with other items of "passive
income" (or, in the case of certain holders, "financial services income").

    It is possible  that, on the date a dividend is paid, the Company will be at
least 50 per cent  owned by U.S.  persons.  Under  Section  904(g)  of the Code,
dividends  paid by a foreign  corporation  that is at least 50 per cent owned by
U.S.  persons may be treated as U.S.  source income  (rather than foreign source
income)  for  U.S.  foreign  tax  credit  purposes  to the  extent  the  foreign
corporation has more than an  insignificant  amount of U.S.  source income.  The
effect  of this  rule may be to treat a  portion  of the  dividends  paid by the
Company as U.S. source income.

    The rules relating to the  determination  of the U.S. foreign tax credit are
complex and you should  consult with your own tax advisors to determine  whether
and to what extent a credit would be available.

DISPOSITION OF COMMON SHARES


    Upon the sale, exchange or other disposition of common shares, a U.S. holder
will recognize  capital gain or loss for U.S.  federal income tax purposes in an
amount  equal to the  difference  between  the U.S.  dollar  value of the amount
realized and the U.S.  holder's tax basis  (determined in U.S.  dollars) in such
common  shares.  Generally,  such gain or loss will be capital  gain or loss and
will be long-term  capital gain or loss if the U.S.  holder's holding period for
such common shares  exceeds one year and any such gain or loss will be income or
loss  from  sources  within  the  United  States  for U.S.  foreign  tax  credit
limitation  purposes.  Long-term capital gain of a noncorporate U.S. holder that
is recognized  before January 1, 2009 is generally subject to a maximum tax rate
of 15 per cent.


PASSIVE FOREIGN INVESTMENT COMPANY


    We believe  that we  currently  are not,  and should not  become,  a passive
foreign investment company (a "PFIC") for U.S. federal income tax purposes,  but
this conclusion is a factual determination that is made annually and thus may be
subject  to change.  If we were to be treated as a PFIC,  unless you elect to be
taxed annually on a mark-to-market basis with respect to the


                                       43




common shares, gain realized on the sale or other disposition of your Debentures
or common  shares would in general not be treated as capital gain.  Instead,  if
you are a U.S. holder, you would be treated as if you had realized such gain and
certain  "excess  distributions"  ratably  over  your  holding  period  for  the
Debentures or common shares and would be taxed at the highest tax rate in effect
for each such year to which the gain was  allocated,  together  with an interest
charge in respect of the tax  attributable  to each such year. In addition,  any
dividends you receive  would be taxable at ordinary  income tax rates and not at
the maximum 15 per cent rate described above.


BACKUP WITHHOLDING AND INFORMATION REPORTING

    If you are a noncorporate U.S. holder,  information reporting  requirements,
on IRS Form 1099, generally will apply to:

    o   payments of principal and interest on your Debentures  within the United
        States, including payments made by wire transfer from outside the United
        States to an account you maintain in the United States,

    o   dividend  payments or other  taxable  distributions  made to you on your
        common shares within the United States, and

    o   the payment of the proceeds  from the sale of your  Debentures or common
        shares effected at a U.S. office of a broker.

    Additionally,  backup  withholding  will apply to such payments if you are a
noncorporate U.S. holder that:

    o   fails to provide an accurate taxpayer identification number,

    o   is notified by the IRS that you have failed to report all  interest  and
        dividends required to be shown on your federal income tax returns, or

    o   in certain circumstances,  fails to comply with applicable certification
        requirements.

TAX EVENT

    The  modification  of the terms of the Debentures by us upon a Tax Event, as
described in  "Description of  Debentures--Optional  Conversion to Full Cash Pay
Debentures  Upon a Tax Event",  could alter the timing of income  recognition by
you with  respect to the  semi-annual  payments of interest due after the option
exercise date.


CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

    The  following is a summary of the  principal  Canadian  federal  income tax
considerations  generally  applicable to a holder (a  "Non-Canadian  holder") in
respect of the  acquisition,  holding,  conversion and disposition of Debentures
purchased  pursuant to this prospectus who, for the purposes of the Canadian Tax
Act and any applicable income tax convention, and at all relevant times, is not,
and is not deemed to be, resident in Canada, deals at arm's length with Inco, is
not  affiliated  with Inco,  holds  Debentures  and will hold Inco common shares
acquired in respect of the  Debentures  as capital  property and does not use or
hold and is not deemed to use or hold the  Debentures  or the Inco common shares
in or in the course of carrying on business in Canada.  Special rules, which are
not discussed in this  summary,  may apply to a  Non-Canadian  holder that is an
insurer that carries on an insurance business in Canada and elsewhere.

    This summary is based on the current  provisions of the Canadian Tax Act and
the  Regulations,  all specific  proposals to amend the Canadian Tax Act and the
Regulations  announced by or on behalf of the Minister of Finance (Canada) prior
to the  date  hereof,  and our  understanding  of the  published  administrative
practices  of the  Canada  Customs  and  Revenue  Agency.  This  summary  is not
exhaustive of all Canadian  federal  income tax  considerations  and,  except as
mentioned  above,  does not take into account or anticipate  any changes in law,
whether by judicial,  governmental or legislative  decision or action or changes
in administrative  practices of the Canada Customs and Revenue Agency,  nor does
it  take  into   account   provincial,   territorial   or  foreign   income  tax
considerations   which  may  vary  from  the   Canadian   federal   income   tax
considerations described herein.

    All amounts  relating to the  ownership  of the  Debentures  and Inco common
shares must be converted  into Canadian  dollars for the purpose of the Canadian
Tax Act and the Regulations.

    THIS  SUMMARY IS OF A GENERAL  NATURE  ONLY AND IS NOT  INTENDED  TO BE, AND
SHOULD NOT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY  PARTICULAR  HOLDER OF
DEBENTURES OR INCO COMMON SHARES AND NO  REPRESENTATION  IS MADE WITH RESPECT TO
THE CANADIAN TAX CONSEQUENCES TO ANY PARTICULAR HOLDER. ACCORDINGLY, PROSPECTIVE
PURCHASERS OF DEBENTURES  SHOULD  CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO
THE  CANADIAN  TAX  CONSIDERATIONS  RELEVANT  TO THEM,  HAVING  REGARD  TO THEIR

                                       44



PARTICULAR CIRCUMSTANCES.

OWNERSHIP OF DEBENTURES

    Under the Canadian Tax Act, the payment to a Non-Canadian  holder by Inco of
interest  or the  amount  owing at  maturity,  on the  redemption,  purchase  or
conversion of a Debenture, will be exempt from Canadian withholding tax.

    In general, a Non-Canadian holder will not be subject to Canadian income tax
on capital gains arising on the  disposition of Debentures  unless the Debenture
constitutes  "taxable Canadian property" to the Non-Canadian holder. A Debenture
will constitute  taxable Canadian  property to a Non-Canadian  holder if, at any
time during the five-year  period  immediately  preceding the  disposition,  the
Non-Canadian holder, persons with whom such holder did not deal at arm's length,
or the  Non-Canadian  holder and  persons  with whom such holder did not deal at
arm's  length  owned 25 per cent or more of the shares of any class or series of
the capital stock of Inco.

OWNERSHIP OF INCO COMMON SHARES

    Under  the  Canadian  Tax  Act,  dividends  on Inco  common  shares  paid or
credited,  or deemed to be paid or credited,  to a  Non-Canadian  holder will be
subject  to  Canadian  withholding  tax at the rate of 25 per cent of the  gross
amount of such dividends.  The rate of this withholding tax may be reduced under
the terms of an  applicable  income  tax  convention.  Under the  Canada--United
States Income Tax Convention (1980),  this withholding tax rate is reduced to 15
per cent or, in the case of a  Non-Canadian  holder that is a corporation  which
beneficially owns at least 10 per cent of the voting shares of Inco, 5 per cent.

    In general, a Non-Canadian holder will not be subject to Canadian income tax
on capital gains arising on the  disposition  of Inco common shares unless those
Inco common shares constitute  "taxable  Canadian  property" to the Non-Canadian
holder.  An Inco common share will  constitute  taxable  Canadian  property to a
Non-Canadian  holder  if,  at any  time  in  the  five-year  period  immediately
preceding  the  disposition,  the  Non-Canadian  holder,  persons with whom such
holder did not deal at arm's length or the Non-Canadian  holder and persons with
whom such holder did not deal at arm's  length  owned 25 per cent or more of the
shares of any class or series of the capital stock of Inco.


                              PLAN OF DISTRIBUTION

    The  Debentures  were issued on March 7, 2003 and March 18, 2003 and offered
and sold in the United States to qualified  institutional  buyers in reliance on
Rule 144A  under the  Securities  Act.  This  prospectus  has not been  filed in
respect of, and will not qualify,  any  distribution of Debentures or underlying
shares in Ontario or any other province or territory of Canada.


    The  holders of the  Debentures  and the  underlying  shares  (together  the
"Registrable  Securities") are entitled to the benefits of a registration rights
agreement, entered into as of March 7, 2003, between us and Morgan Stanley & Co.
Incorporated  and Salomon Smith Barney Inc. (now Citigroup  Global Markets Inc.)
(the  "Registration  Rights  Agreement"),  pursuant  to which we have filed this
short form prospectus with the Ontario Securities  Commission under the Canadian
shelf prospectus system and a registration  statement  including this prospectus
with the Securities and Exchange Commission under the Securities Act (the "Shelf
Registration Statement") covering resales of the Registrable Securities.


    A list of the  holders  of  Registrable  Securities  who  have  delivered  a
completed  selling  securityholder's  questionnaire  to us (each,  an  "Electing
Holder") is set out in Schedule A to this prospectus, which is incorporated into
and forms part of this  prospectus and which may be updated by way of supplement
to  this  prospectus.  All  shelf  information  omitted  from  this  base  shelf
prospectus  will be  contained in a shelf  supplement  that will be delivered to
purchasers  together  with this base shelf  prospectus.  Each  shelf  prospectus
supplement will be incorporated by reference into this base shelf  prospectus as
of the date of the shelf prospectus  supplement and only for the purposes of the
distribution  to which the shelf  prospectus  supplement  pertains.  Each  shelf
prospectus  supplement to this base shelf prospectus will contain a current list
of the Electing Holders.

    Each Electing  Holder is the beneficial,  but not the registered,  holder of
the amount payable at maturity of Debentures  shown in Schedule A, any or all of
which may be sold by the  Electing  Holder  at any  time,  or from time to time,
pursuant to this  prospectus,  and the amount  payable at maturity of Debentures
held by such Electing  Holder shall  thereafter be reduced to the extent of such
sales.  All of the Debentures held by the Electing  Holders were either acquired
by them upon the issuance of the  Debentures on March 7, 2003 or March 18, 2003,
or in subsequent transactions thereafter.

    We are registering the Debentures and the underlying  shares covered by this
prospectus  under the  Securities  Act to permit any of the Electing  Holders to
conduct public secondary trading of these securities from time to time after the
date of this  prospectus in accordance  with the federal  securities laws of the
United States. We have agreed, in the Registration Rights

                                       45



Agreement, to bear all fees and expenses,  other than underwriting discounts and
selling  commissions,  in  connection  with  the  registration  and  sale of the
Registrable Securities covered by this prospectus.  Additionally, we have agreed
to indemnify the holders of Registrable  Securities against certain liabilities,
including  liabilities  under the Securities  Act, and each Electing  Holder has
agreed to indemnify us, other holders and any persons who control us, as defined
in the federal securities laws of the United States,  against any liability with
respect to any information  furnished by such holder in writing to us (including
the  selling  securityholder's  questionnaire)  expressly  for use in the  Shelf
Registration Statement.

    We will not receive  any of the  proceeds  from the sale of the  Registrable
Securities by the Electing Holders. We have been advised by the Electing Holders
that  the  Electing  Holders  may  sell all or any  portion  of the  Registrable
Securities beneficially owned by them and offered hereby from time to time:

    o   directly; or

    o   through   underwriters,   broker-dealers  or  agents,  who  may  receive
        compensation in the form of discounts,  commissions or concessions  from
        the  Electing   Holders  or  from  the  purchasers  of  the  Registrable
        Securities from whom they may act as agent.

    The  Registrable  Securities  may be sold  from  time to time in one or more
transactions at:

    o   fixed prices, which may be changed;

    o   varying prices determined at the time of sale; or

    o   negotiated prices.

     The prices  will be  determined  by the  Electing  Holders or by  agreement
between the Electing Holders and underwriters or dealers who may receive fees or
commissions in connection with the sale. The aggregate  proceeds to the Electing
Holders from the sale of the Registrable  Securities offered by them hereby will
be  the  purchase  price  of  the  Registrable   Securities  less  discount  and
commissions, if any.

     The  sales  described  in  the  preceding  paragraph  may  be  effected  in
transactions:

    o   on any U.S. national  securities  exchange or quotation service on which
        the  Registrable  Securities  may be listed or quoted at the time of the
        sale, including the NYSE in the case of the underlying shares;

    o   in the over-the-counter market;

    o   in  transactions  otherwise than on such exchanges or services or in the
        over-the-counter market; or

    o   through the writing of options.

     These transactions may include block  transactions or crosses.  Crosses are
transactions in which the same broker acts as agent on both sides of the trade.

     Once any  Registrable  Security is sold by any Electing  Holder pursuant to
the Shelf Registration  Statement,  such Registrable  Security is not thereafter
covered by the Shelf Registration  Statement even if subsequently  reacquired by
an Electing Holder.

     Our  outstanding  common shares are listed on the NYSE and the TSX, each of
which has approved  the listing of the  underlying  shares.  We do not intend to
list  the   Debentures  for  trading  on  any  national   securities   exchange.
Accordingly,  no  assurance  can be given as to the  development  of any trading
market  for  the  Debentures.   See  Risk  Factors  -  Trading  Market  for  the
Debentures".

     In  order  to  comply  with  the  securities  laws of  certain  states,  if
applicable,   the  Debentures  and  underlying   shares  may  be  sold  in  such
jurisdictions only through registered or licensed brokers or dealers.

     The selling  securityholders  and any underwriters,  dealers or agents that
participate in the distribution of the Debentures and underlying  shares offered
under this  prospectus  may be deemed to be  underwriters  within the meaning of
Section  2(11)  of  the  Securities  Act,  and  any  discounts,  commissions  or
concessions  received by them  pursuant to the sale of such  securities  by

                                       46



them might be deemed to be  underwriting  discounts  and  commissions  under the
Securities Act.

     We will be  permitted  pursuant to the  Registration  Rights  Agreement  to
suspend  the use of this  prospectus  that  is  part of the  Shelf  Registration
Statement   under   certain   circumstances   relating   to  pending   corporate
developments, public filings with the SEC and similar events for a period not to
exceed 45 days in any three-month period and 120 days in any 12-month period.

     In addition,  any securities  covered by this prospectus  which qualify for
sale pursuant to Rule 144 or Rule 144A of the  Securities  Act may be sold under
Rule 144 or Rule 144A  rather  than  pursuant  to this  prospectus.  There is no
assurance that any selling securityholder will sell any or all of the Debentures
or   underlying   shares   described  in  this   prospectus,   and  any  selling
securityholder  may transfer,  devise or gift such securities by other means not
described in this prospectus.


                           VALIDITY OF THE DEBENTURES

    The validity of the Debentures  under New York law was passed upon for us by
Sullivan & Cromwell  LLP, New York,  New York.  Certain other legal matters were
passed on for us by Stuart F. Feiner,  Inco's Executive Vice President,  General
Counsel and Secretary,  Mark J. Travers,  Inco's Assistant General Counsel,  and
Osler, Hoskin & Harcourt LLP, Toronto,  Ontario. As of the date hereof,  certain
lawyers with Osler,  Hoskin & Harcourt LLP, own, directly or indirectly,  in the
aggregate, less than one per cent of our outstanding common shares.
