                                     PART I

Item 1. Business

General

     International Paper Company (the Company or International Paper, which may
be referred to as we or us), is a global forest products, paper and packaging
company that is complemented by an extensive distribution system, with primary
markets and manufacturing operations in the United States, Canada, Europe, the
Pacific Rim, and South America. Substantially all of our businesses have
experienced, and are likely to continue to experience, cycles relating to
available industry capacity and general economic conditions. We are a New York
corporation and were incorporated in 1941 as the successor to the New York
corporation of the same name organized in 1898. Our home page on the Internet
is www.internationalpaper.com. You can learn more about us by visiting that
site.

     In the United States at December 31, 2000, the Company operated 35 pulp,
paper and packaging mills, 105 converting and packaging plants, 46 wood
products facilities, seven specialty panels and laminated products plants and
eight specialty chemicals plants. Production facilities at December 31, 2000 in
Europe, Asia, Latin America, South America and Canada included 15 pulp, paper
and packaging mills, 48 converting and packaging plants, 15 wood products
facilities, three specialty panels and laminated products plants and seven
specialty chemicals plants. We distribute printing, packaging, graphic arts,
maintenance and industrial products through over 300 distribution branches
located primarily in the United States. At December 31, 2000, we owned or
managed approximately 12 million acres of forestlands in the United States,
mostly in the South, 1.5 million acres in Brazil and had, through licenses and
forest management agreements, harvesting rights on government-owned timberlands
in Canada.

     Through Carter Holt Harvey, a New Zealand company which is approximately
50.4% owned by International Paper, the Company operates five mills producing
pulp, paper, packaging and tissue products, 26 converting and packaging plants
and 56 wood products manufacturing and distribution facilities, primarily in
New Zealand and Australia. Carter Holt Harvey distributes paper and packaging
products through seven distribution branches located in New Zealand and
Australia. In New Zealand, Carter Holt Harvey owns approximately 820,000 acres
of forestlands.

     For financial reporting purposes, our businesses are separated into six
segments: Printing Papers; Industrial and Consumer Packaging; Distribution;
Forest Products; Chemicals and Petroleum; and Carter Holt Harvey. A description
of these business segments can be found on pages 7 through 13 of our 2000
Annual Report to Shareholders (Annual Report), which information is
incorporated herein by reference.

     From 1995 through 2000, International Paper's capital expenditures
approximated $8.8 billion, excluding mergers and acquisitions. These
expenditures reflect our continuing efforts to improve product quality and
environmental performance, lower costs, and improve forestlands. Capital
spending in 2000 was $1.4 billion and is budgeted to be approximately $1.2
billion in 2001. This amount is below our annual depreciation and amortization
expense of $2 billion. You can find more information about capital expenditures
on pages 13 and 14 of our Annual Report, which information is incorporated
herein by reference.

     Discussions of mergers and acquisitions can be found on pages 6, 13, 14,
39 and 40 of the Annual Report, which information is incorporated herein by
reference.

     You can find discussions of restructuring charges and other special items
on pages 15 through 23 and 41 through 49 of the Annual Report, which
information is incorporated herein by reference.

     Throughout this 10-K report, we 'incorporate by reference' certain
     information in parts of other documents filed with the Securities and
     Exchange Commission (SEC). The SEC permits us to disclose important
     information by referring to it in that manner. Please refer to such
     information.

Financial Information Concerning Industry Segments

     The financial information concerning segments is set forth on pages 30 and
31 of the Annual Report, which information is incorporated herein by reference.

   Financial Information About International and Domestic Operations

     The financial information concerning international and domestic operations
and export sales is set forth on page 31 of the Annual Report, which
information is incorporated herein by reference.

   Competition and Costs

     Despite the size of the Company's manufacturing capacities for paper,
paperboard, packaging and pulp products, the markets in all of the cited
product lines are large and highly fragmented. The markets for wood and
specialty products are similarly large and fragmented. There are numerous
competitors, and the major markets, both domestic and international, in which
the Company sells its principal products are very competitive. These products
are in competition with similar products produced by others, and in some
instances, with products produced by other industries from other materials.

     Many factors influence the Company's competitive position, including
prices, costs, product quality and services. You can find more information
about the impact of prices and costs on operating profits on pages 6 through 13
of the Annual Report, which information is incorporated herein by reference.

   Marketing and Distribution

     The Company sells paper and packaging products through our own sales
organization directly to users or converters for manufacture. Sales offices are
located throughout the United States as well as internationally. We also sell
significant volumes of products through paper merchants and distributors,
including facilities in our distribution network.

     We market our U.S. production of lumber and plywood through independent
and Company-owned distribution centers. Specialty products are marketed through
various channels of distribution.

   Description of Principal Products

     The Company's principal products are described on pages 7 through 9 of the
Annual Report, which information is incorporated herein by reference.

     Production of major products for 2000, 1999 and 1998 was as follows:

   Research and Development

     The Company operates research and development centers at Sterling Forest,
New York; Cincinnati, Ohio; Kaukauna, Wisconsin; West Chicago, Illinois;
Odenton, Maryland; Jacksonville, Florida; Savannah, Georgia; Saint- Priest,
France; Annecy, France; a regional center for applied forest research in
Bainbridge, Georgia; a forest biotechnology center in Rotorua, New Zealand; and
several product laboratories. We direct research and development activities to
short-term, long-term and technical assistance needs of customers and operating
divisions; process, equipment and product innovations; and improve profits
through tree generation and propagation research. Activities include studies on
improved forest species and management; innovation and improvement of pulping,
bleaching, chemical recovery, papermaking and coating processes; packaging
design and materials development; reduction of environmental discharges; re-use
of raw materials in manufacturing processes; recycling of consumer and
packaging paper products; energy conservation; applications of computer
controls to manufacturing operations; innovations and improvement of products;
and development of various new products. Our development efforts specifically
address product safety as well as the minimization of solid waste. The cost to
the Company of its research and development operations in 2000 was $92 million,
including Champion for the period of July- December, $88 million in 1999, and
$144 million in 1998.

   Environmental Protection

     The Company is subject to extensive federal and state environmental
regulation as well as similar regulations in all other jurisdictions in which
it operates. Our continuing objectives are to: (1) control pollutants
discharged into the air, water and groundwater to avoid adverse impacts on the
environment, (2) make continual improvements in environmental performance, and
(3) maintain 100% compliance with applicable laws and regulations. A total of
$190 million was spent in 2000 for capital projects to control environmental
releases into the air and water, and to assure environmentally sound management
and disposal of waste. We expect to spend approximately $136 million in 2001
for similar capital projects, including the costs to comply with the
Environmental Protection Agency's (EPA) Cluster Rule regulations. Amounts to be
spent for environmental control projects in future years will depend on new
laws and regulations and changes in legal requirements and environmental
concerns. Taking these uncertainties into account, our preliminary estimate for
additional environmental appropriations during the year 2002 is approximately
$164 million and during the year 2003 is approximately $143 million.

     On April 15, 1998, the EPA issued final Cluster Rule regulations that
established new requirements regarding air emissions and wastewater discharges
from pulp and paper mills to be met by 2006. The projected costs included in
our estimate related to the Cluster Rule regulations for the years 2001 through
2002 are $116 million. Projected


                                       5




Cluster Rule costs for 2003 through 2006 are in the range of $330 million to
$370 million. Included in these estimates are costs associated with combustion
source standards for the pulp and paper industry, which were issued by the EPA
on January 12, 2001. The final cost depends on the outcome of the Cluster Rule
water regulations for pulp and paper categories other than bleached kraft and
soda. Regulations for these categories are not likely to become final until
late 2001. We estimate that annual operating costs, excluding depreciation,
will increase approximately $22 million when these regulations are fully
implemented.

     Additional regulatory requirements that may affect future spending include
the EPA's requirements for states to assess current surface water loading from
industrial and area sources. This process, called Total Maximum Daily Load
(TMDL) allocation, could result in reduced allowable treated effluent
discharges from our manufacturing sites. To date there have been no significant
impacts due to the TMDL process, as the majority of our manufacturing sites
operate at levels significantly below allowable waste loadings.

     In recent years, the EPA has undertaken significant air quality
initiatives associated with nitrogen oxide emissions, regional haze, and
national ambient air quality standards. When regulatory requirements for new
and changing standards are finalized, we will add any resulting future cost
projections to our expenditure forecast.

     The Company has been named as a potentially liable party in a number of
environmental remediation actions under various federal and state laws,
including the Comprehensive Environmental Response, Compensation and Liability
Act (CERCLA). Related costs are recorded in the financial statements when they
are probable and reasonably estimable. As of December 31, 2000, these
liabilities totaled approximately $170 million. Completion of these actions is
not expected to have a material adverse effect on the Company's financial
condition or results of operations.

     The Company expects the significant effort it has made in the analysis of
environmental issues and the development of environmental control technology
responses will enable it to keep costs for compliance with environmental
regulations at, or below, industry averages. According to the National Council
for Air & Stream Improvement (NCASI), pulp and paper industry averages for
environmental capital expenditures, expressed as a percentage of total capital
expenditures, ranged from 12% to 13% for the years 1995 through 1998. 1998 is
the last year for which public reports are available. During that same time
period, the Company's environmental capital expense, expressed as a percentage
of total capital expense, ranged from approximately 7% to 10%. In 1999 and
2000, the Company's environmental capital expense, expressed as a percentage of
total capital expense, were slightly below 8% and 13.5%, respectively. The
Company believes these percentages continue to be significantly below industry
averages.

     You can find a further discussion of environmental issues on pages 24 and
25 of the Annual Report, which information is incorporated herein by reference.

     You can also find additional information about environmental matters in
the Company's 1999-2000 Environment, Health & Safety Annual Environmental
Report, which can be obtained by contacting the Company or through the
Company's website.

   Employees

     As of December 31, 2000, we had approximately 112,900 employees, 77,000 of
whom were located in the United States. Of the domestic employees,
approximately 49,000 are hourly employees, approximately 23,000 of whom are
represented by the Paper, Allied-Industrial, Chemical and Energy International
Union.

     At December 31, 2000, employee reductions relating to the Union Camp
merger totaled approximately 2,200, based on a comparison of year end 2000
actual head count versus 1998 budget. During 2000, we completed the Union Camp
merger-related integration benefits program, eliminating 1,062 employees of the
combined company. Under a Union Camp restructuring plan implemented in 1998
before the merger, another 540 positions were eliminated. Approximately 600
additional positions of the combined company were eliminated where the
individuals affected were not eligible for benefits under these programs.


                                       6




     During 2000, labor agreements were ratified at seven mills. During 2001,
labor agreements are scheduled to be negotiated at five mills: Georgetown,
Erie, Pensacola, Sartell and Hudson River.

     During 2000, 27 labor agreements were settled in non-papermill operations.
Settlements included 12 in paper converting, six in building materials, six in
distribution and three in chemicals. At year end, one open contract existed
where negotiations were in progress. During 2001, 26 non-papermill operations
will negotiate new labor agreements.

     Approximately 5,500 of our U.S. based hourly employees are subject to
labor agreements that are scheduled to be negotiated during 2001.

Item 2.  Properties

Forestlands

     The principal raw material used by International Paper is wood in various
forms. As of December 31, 2000, the Company or its subsidiaries owned or
controlled approximately 12 million acres of forestlands in the United States,
1.5 million acres in Brazil and had, through licenses and forest management
agreements, harvesting rights on government-owned timberlands in Canada. An
additional 820,000 acres of forestlands in New Zealand were held through Carter
Holt Harvey, a consolidated subsidiary of International Paper.

     During 2000, the U.S. forestlands supplied 16 million tons of roundwood to
the Company's U.S. facilities. This amounted to the following percentages of
the roundwood requirements of its U.S. mills and forest products facilities:
15% in its Northern mills and 38% in its Southern mills. The balance was
acquired from other private industrial and nonindustrial forestland owners,
with only an insignificant amount coming from public lands of the United States


                                       7




government. In addition, in 2000, seven million tons of wood were sold to other
users. In November 1994, we adopted the Sustainable Forestry Principles
developed by the American Forest and Paper Association in August 1994.

     Given the size, scope and complexity of our business interests, we
continuously examine and evaluate a wide variety of business opportunities and
planning alternatives, including possible acquisitions and sales or other
dispositions of properties. You can find planned capital investments for 2001,
dispositions, and restructuring activities as of December 31, 2000 on pages 6
and 13 through 23 of the Annual Report, which information is incorporated

Item 3.  Legal Proceedings

Masonite Litigation

     Three nationwide class action lawsuits relating to products manufactured
by Masonite Corporation that were filed against the Company have been settled
in recent years.

     The first suit alleged that hardboard siding manufactured by Masonite
fails prematurely, allowing moisture intrusion that in turn causes damage to
the structure underneath the siding (Hardboard Lawsuit). The class consisted of
all U.S. property owners having Masonite hardboard siding installed on and
incorporated into buildings between 1980 and January 15, 1998. The Court
granted final approval of the settlement on January 15, 1998. The settlement
provides for monetary compensation to class members meeting the settlement
requirements on a claims-made basis. It also provides for the payment of
attorneys' fees equaling 15% of the settlement amounts paid to class members,
with a non-refundable advance of $47.5 million plus $2.5 million in costs.

     The second suit made similar allegations with regard to Omniwood siding
manufactured by Masonite (Omniwood Lawsuit). The class consisted of all U.S.
property owners having Omniwood siding installed on and incorporated into
buildings from January 1, 1992 to January 6, 1999.

     The third suit alleged that Woodruf roofing manufactured by Masonite is
defective and causes damage to the structure underneath the roofing (Woodruf
Lawsuit). The class consisted of all U.S. property owners who had incorporated
and installed Masonite Woodruf roofing from January 1, 1980 to January 6, 1999.

     The Court granted final approval of the settlements of the Omniwood and
Woodruf Lawsuits on January 6, 1999. The settlements provide for monetary
compensation to class members meeting the settlement requirements on a
claims-made basis, and provide for payment of attorneys' fees equaling 13% of
the settlement amounts paid to class members with a non-refundable advance of
$1.7 million plus $75,000 in costs for each of the two cases.


                                       9




     Reserves for these matters total $92 million at December 31, 2000, net of
expected future insurance recoveries of $43 million. This amount includes $25
million added to the reserve for hardboard siding claims in the fourth quarter
of 1999 (some of which has now been paid to claimants) and an additional $125
million added to that reserve in the third quarter of 2000 to cover an expected
shortfall, resulting primarily from a higher number of hardboard siding claims
than anticipated. It is reasonably possible that the higher number of hardboard
siding claims might be indicative of the need for one or more future additions
to this reserve. However, whether or not any future additions to this reserve
become necessary, we believe that these settlements will not have a material
adverse effect on our consolidated financial position or results of operations.

     Through December 31, 2000, net settlement payments of $277 million,
including the $51 million of non- refundable advances of attorneys' fees
discussed above, have been made. Also, we have received $27 million related to
these matters from our insurance carriers through December 31, 2000.
International Paper and Masonite have the right to terminate each of the
settlements after seven years from the dates of final approval. The liability
for these matters will be retained after the planned sale of Masonite is
completed.

Other Litigation

     In March and April 2000, Champion and 10 members of its board of directors
were served with six lawsuits that have been filed in the Supreme Court for the
State of New York, New York County. Each of the suits purports to be a class
action filed on behalf of Champion shareholders and alleges that the defendants
breached their fiduciary duties in connection with the proposed merger with
UPM-Kymmene Corporation and the merger proposal from International Paper. The
lawsuits seek compensatory and other damages and costs and expenses associated
with the litigation. Champion has filed a motion to dismiss, which as of
February 26, 2001 has not been decided.

     On May 14, 1999, and May 18, 1999, two lawsuits were filed against
International Paper, the former Union Camp Corporation (Union Camp) and other
manufacturers of linerboard. These suits allege that the defendants conspired
to fix prices for linerboard and corrugated sheets during the period October 1,
1993, through November 30, 1995. Both lawsuits were filed seeking nationwide
class certification. The lawsuits allege that various purchasers of corrugated
sheets and corrugated containers were injured as a result of the alleged
conspiracy. These lawsuits seek injunctive relief as well as treble damages and
other costs and expenses associated with the litigation. The cases have been
consolidated in federal court in the Eastern District of Pennsylvania.
Defendants' motions to dismiss the cases were denied on October 4, 2000.
Plaintiffs filed motions for class certification on January 10, 2001, which
were pending as of February 26, 2001.

     Purchasers of high-pressure laminates have filed a number of purported
class actions under the federal antitrust laws in various federal district
courts in different states, alleging that International Paper's Nevamar
division participated in a price-fixing conspiracy with competitors. These
lawsuits seek injunctive relief as well as treble damages and other costs and
expenses associated with the litigation. These cases have been consolidated in
federal district court in New York. Indirect and direct purchasers of
high-pressure laminates have also filed similar purported class action cases
under various state antitrust and consumer protection statutes in California,
Florida, Maine, Michigan, Minnesota, New Mexico, New York, North Dakota, South
Dakota, Tennessee and the District of Columbia. International Paper filed a
motion to dismiss one of the cases in federal court, which was denied by the
court without prejudice. The federal plaintiffs filed a consolidated amended
complaint on February 22, 2001. As of February 26, 2001, International Paper
has filed a motion to dismiss the case pending in New York State court and has
filed answers in California, New Mexico, South Dakota and one of two complaints
filed in Michigan. Answers are not yet due in the remaining state cases.

Other Environmental

     In April 1999, the Franklin, Virginia mill received a Notice of Violation
(NOV) from the EPA, Region 3 in Philadelphia, and an NOV from the Commonwealth
of Virginia alleging that the mill violated the Prevention of Significant
Deterioration (PSD) regulations. The Franklin mill was owned by Union Camp at
that time and was one of seven paper mills in Region 3 owned by different
companies that received similar notices of violation. Union


                                       10




Camp merged with International Paper on April 30, 1999, and International Paper
has entered into negotiations with the EPA and the Commonwealth of Virginia.

     The Franklin mill NOVs were issued in connection with the EPA's well
publicized PSD air permit enforcement initiative against the paper industry. In
1999, our paper mills in Kaukauna, Wisconsin and Augusta, Georgia received
requests for information from the EPA regarding compliance with the PSD
regulations. Three additional facilities received information requests in 2000,
and the EPA's initiative may result in similar actions at other facilities.

     In August 1998, the former Union Camp Corporation informed the Virginia
Department of Environmental Quality (DEQ) of certain New Source Performance
Standards (NSPS) permitting discrepancies related to a power boiler at the
paper mill in Franklin, Virginia. On April 11, 2000, International Paper and
the DEQ entered into a consent order that resolved the matter for a civil
penalty of $134,000.

     In November 1999, the Wisconsin Department of Natural Resources filed a
civil complaint alleging past exceedences of air permit limits at the former
Union Camp flexible packaging facility located in Tomah, Wisconsin. The matter
was settled on November 2, 2000 for a civil penalty of $60,000.

     On December 30, 1999, the Company entered into a Consent Order with the
Florida Department of Environmental Protection relating to alleged violations
of the wastewater discharge permit at the Company's Pensacola, Florida, mill.
The Consent Order requires the Company to take additional steps to control the
discharge of suspended solids, nutrients and oxygen-consuming material in the
mill's wastewater and to pay a civil penalty of $137,730. The Consent Order has
not yet become effective due to the filing of administrative appeals by third
parties.

     In February 2000, the Town of Lyman, South Carolina, issued an
administrative order alleging past violations of a wastewater pretreatment
permit at the former Union Camp folding carton facility in Spartanburg, South
Carolina. While International Paper has satisfied the terms of the order, the
Town of Lyman recently indicated it may seek penalties and other surcharges
that together may exceed $100,000. We are engaged in settlement discussions
with the Town of Lyman.

     As of February 26, 2001, there were no other pending judicial proceedings,
brought by governmental authorities against International Paper, for alleged
violations of applicable environmental laws or regulations. International Paper
is engaged in various other proceedings that arise under applicable
environmental and safety laws or regulations, including approximately 97 active
proceedings under the CERCLA and comparable state laws. Most of these
proceedings involve the cleanup of hazardous substances at large commercial
landfills that received waste from many different sources. While joint and
several liability is authorized under the CERCLA, as a practical matter,
liability for CERCLA cleanups is allocated among the many potential responsible
parties. Based upon previous experience with respect to the cleanup of
hazardous substances and upon presently available information, International
Paper believes that it has no or de minimis liability with respect to 18 of
these sites; that liability is not likely to be significant at 51 sites; and
that estimates of liability at 28 of these sites is likely to be significant
but not material to International Paper's consolidated financial position or
results of operations.

     On June 19, 2000, before International Paper completed the acquisition of
Champion, Champion entered into a Consent Order with the Maine Department of
Environmental Protection that resolved allegations of past wastewater and
reporting deficiencies at Champion's lumber mills in Milford and Passadumkeag,
Maine. The U.S. EPA and the U.S. Attorney's Office in Maine have since that
time commenced a grand jury investigation of the same allegations.

     We are also involved in other contractual disputes, administrative and
legal proceedings and investigations of various types. While any litigation,
proceeding or investigation has an element of uncertainty, we believe that the
outcome of any proceeding, lawsuit or claim that is pending or threatened, or
all of them combined, will not have a material adverse effect on our
consolidated financial position or results of operations.
