CERTAIN TERMS AND CONVENTIONS

Celulosa Arauco y Constitución S.A. is a corporation (sociedad anónima) organized under the laws of the Republic of
Chile, and subject to the rules of the Chilean public corporations (sociedades anónimas abiertas). Except where otherwise specified or the context otherwise requires, when we refer to the Company, Arauco or
we, in this annual report, we mean Celulosa Arauco y Constitución S.A. and its consolidated subsidiaries. When we refer to Chile, we mean the Republic of Chile; when we refer to Argentina, we mean the
Argentine Republic; when we refer to Brazil, we mean the Federative Republic of Brazil; and when we refer to Uruguay, we mean the Oriental Republic of Uruguay. All references to tons are to metric tons (1,000
kilograms), which equal 2,204.7 pounds. One hectare equals 10,000 square meters or 2.471 acres. Discrepancies in any table between totals and the sums of the amounts listed are due to rounding.

Unless otherwise specified, all references to $, U.S.$, U.S. dollars or dollars are to
United States dollars; references to Chilean pesos or Ch$ are to Chilean pesos; references to Argentine pesos or Ar$ are to Argentine pesos; references to Brazilian reals or
R$ are to Brazilian reals; references to  or euro are to the euro, the single European currency established pursuant to the European Economic and Monetary Union; and references to UF are
to Unidades de Fomento. The UF is a unit of account that is linked to, and adjusted daily to reflect changes in, the Chilean consumer price index reported by the Chilean National Institute of Statistics (Instituto Nacional de
Estadísticas). At December 31, 2009, one UF equaled U.S.$41.3 and Ch$20,942.9.

PRESENTATION OF FINANCIAL
INFORMATION

This annual report includes our audited consolidated balance sheets of Arauco and our subsidiaries as of
December 31, 2009 and 2008 and the related consolidated statements of income, shareholders equity and cash flows for each of the two years in the period ended December 31, 2009 (collectively, the audited consolidated financial
statements or financial statements).

Since January 1, 2009, our consolidated financial statements are
and will be prepared in accordance with the International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). Prior to our transition to IFRS, our consolidated financial
statements were prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP.

Our
consolidated financial information as of and for the year ended December 31, 2008 included in our audited consolidated financial statements was restated in accordance with IFRS. See Note 2 to our audited consolidated financial statements as of
and for the year ended December 31, 2009, included elsewhere in this annual report.

IFRS differs in certain significant
respects from U.S. GAAP. As a result, our financial information presented under IFRS is not directly comparable to our financial information presented under U.S. GAAP, and readers should avoid such a comparison.

Translations of certain amounts into dollars at a specified rate have been included in this annual report. Unless otherwise indicated,
the U.S. dollar equivalent for information in Chilean pesos is based on the observed exchange rate (dólar observado) reported by the Central Bank of Chile (Banco Central de Chile), which we refer to as the Central Bank, for
December 31, 2009, which was Ch$507.10 to U.S.$1.00. The observed exchange rate is, for any date, the average exchange rate at which transactions are actually carried out in the Formal Exchange Market (Mercado Cambiario Formal) on the
previous day, as certified by the Central Bank on the following business day. You should not construe these translations as representations that the Chilean peso amounts actually represent such dollar amounts or could be converted into dollars at
the rates indicated or at any other rate. On June 22, 2010, the observed exchange rate was Ch$530.32 to U.S.$1.00. For information regarding historical rates of exchange in Chile from January 1, 2004 see Item 3. Key
InformationExchange Rates.

The Federal Reserve Bank of New York does not report a noon buying rate for Chilean
pesos.

Unless otherwise specified, references to the devaluation or the appreciation of the Chilean peso against the U.S.
dollar are in nominal terms (without adjusting for inflation), based on the observed exchange rates for the relevant period.

RISK FACTORS

We are subject to various changing economic, political, social and competitive conditions, particularly in our principal markets. Any
of the following risks, if they actually occur, could materially and adversely affect our business, financial condition, results of operations and cash flows.

Risks Relating to Arauco and the Forestry Industry

Environmental concerns led us to temporarily suspend our operations at the Valdivia Mill in 2005, which adversely affected, and in the future may
continue to adversely affect, our business, financial condition, results of operations and cash flows

Our operations
at the Valdivia Mill, an industrial development in the Province of Valdivia in the Fourteenth Region of Chile (which was previously part of the Tenth Region of Chile), have been subject to environmental scrutiny by Chilean environmental regulators
and the Chilean public since the mill began its operations in 2004. A variety of concerns and claims were raised regarding potential environmental impacts in the area. Primarily, it was alleged that the mills operations impacted the nearby
Carlos Anwandter Nature Sanctuary and contributed to the migration and death of black-neck swans living in the area. In connection with an environmental administrative proceeding, environmental regulators required us to temporarily suspend
operations at the Valdivia Mill for approximately one month in January 2005. We resumed operations at the mill on February 18, 2005.

On June 8, 2005, we voluntarily suspended operations at the Valdivia Mill, until certain technical and legal conditions could be
clarified with the applicable regulatory authorities. We estimate this voluntary suspension resulted in a loss of sales of approximately U.S.$1.0 million per day and a loss of profits of approximately U.S.$250,000 per day. Pursuant to the decision
of our board of directors, based on certain clarifications provided by the Environmental Regional Commission (Comisión Regional del Medio Ambiente), or COREMA, of the Tenth Region of Chile, the mill resumed operations on
August 12, 2005 at 80% of its authorized production capacity, after 64 days of suspended operations. In order to achieve the full production capacity authorized by applicable permits, the mill had to fulfill certain new requirements established
by the COREMA. On January 18, 2008, the COREMA authorized the Valdivia Mill to return to its annual authorized production capacity of 550,000 metric tons. The mill gradually increased its production over a four-month period starting in March
2008 and reached full capacity in June 2008. The suspension of operations at the Valdivia Mill adversely affected our business, financial condition, results of operations and cash flows. Any future suspension of operations at the Valdivia Mill or at
any other of our significant operating plants can be expected to have similar adverse effects. We offer no assurance that the Valdivia Mill will be able to operate without further interruption. See Item 4. Information on the
CompanyDescription of BusinessPulpPulp millsChileValdivia Mill and Item 8. Financial InformationLegal Proceedings.

In June 2007, we submitted to the COREMA of the Tenth Region of Chile an environmental impact study for the implementation of substantial
technological improvements on the quality of the effluents generated by the Valdivia Mill. On June 30, 2008, the COREMA approved that environmental impact study. However, the approval was subject to certain conditions that, in the opinion of
Arauco, affected the feasibility of the project. For such reason, Arauco filed an appeal (recurso de reclamación) before the Directive Council (Consejo Directivo) of the Environmental National Commission (Comisión
Nacional del Medio Ambiente), or CONAMA, challenging the conditions. Such appeal (recurso de reclamación) was partially accepted by the CONAMA. However, some conditions that affect the feasibility of the project were maintained. As
a consequence, on September 17, 2009, we presented another appeal (recurso de reclamación) before the ordinary courts of justice, which has not been resolved as of the date of this annual report.

On February 19, 2009, we submitted to the COREMA of the Fourteenth Region of Chile an environmental impact study for the
construction of a pipeline to discharge the Valdivia Mills wastewater in the Pacific Ocean near Punta Maiquillahue, in compliance with the resolution of the COREMA, which required that such wastewater be discharged in a body of water other
than the Cruces River, the Carlos Anwandter Nature Sanctuary or their sources. The pipeline would transport the wastewaters of the Valdivia mill through an extension of 37 kilometers from the Valdivia mill to Punta Maiquillahue and would finally
discharge the wastewater two kilometers inside the Pacific Ocean. Such environmental impact study was approved by the COREMA by resolution dated February 24, 2010,

which has been partially challenged by us before the Directive Council (Consejo Directivo) of the CONAMA. As of the date of this annual report, the Directive Council of the CONAMA has not
resolved the action presented by us. As stated in the environmental impact study, the construction of this pipeline will commence once (i) the CONAMA finally and definitively approves the environmental impact study in its final form, and
(ii) all necessary permits for the construction of the pipeline have been issued by the competent authorities. The period of construction has been estimated at 24 months of actual work. According to the environmental impact study, once
construction has been initiated, if it is delayed for reasons not attributable to us (such as events of force majeure or acts from third parties), the construction period will be deemed extended for the duration of such delay. Once the construction
of the pipeline has been completed, we will conduct a 6-month trial phase of the pipeline and will then begin normal operations.

Approval by the COREMA or by the judicial courts of our appeal (as respectively applicable) regarding the resolutions that approved the
environmental impact study of the pipeline and the improvement of the quality of the effluents projects, as well as the construction and operation of the pipeline are each subject to many environmental, regulatory, engineering and political
uncertainties. As a result, we cannot provide any assurances that the projects will be finally approved as requested or completed. If either the request for the necessary permits for the construction of the pipeline is rejected, or the installation
of the pipeline is delayed for reasons attributable to us, we may face sanctions that include warnings, fines or the revocation of the Valdivia Mills environmental permit for operation. Alternatively, if any rejection or delays are
attributable to reasons beyond our control, we believe that the environmental authority should extend the applicable deadlines. However, we can provide no assurances that any deadline extensions would be granted, even if we comply with all the
requirements that may be set forth by those authorities. See Item 4. Information on the CompanyDescription of BusinessPulpPulp millsChileValdivia Mill and Item 8. Financial InformationLegal
Proceedings.

Environmental concerns led us to suspend our operations at the Licancel Mill, which adversely affected our business,
financial condition, results of operations and cash flows

Beginning in June 2007, our operations at the Licancel
Mill, a pulp mill located in the Seventh Region of Chile, became subject to environmental scrutiny by Chilean environmental regulators and the public, which arose in connection with the death of fish in the Mataquito River, approximately 15
kilometers downstream of the mill. As a result, Chilean authorities, including certain public health authorities and the Superintendencia de Servicios Sanitarios(Sanitary Services Superintendency), required that we suspend activities at the
Licancel Mill and that we suspend any further discharges into the river. We estimate that the suspension of operations at the Licancel Mill resulted in a total loss of profits of approximately U.S.$24 million. Several administrative and judicial
proceedings have been commenced regarding the events at the Licancel Mill and the death of fish at the Mataquito River. The mill resumed operations during January 2008. For further details in respect of the proceedings related to the 2007 suspension
of operations at the Licancel Mill, see Item 8. Financial InformationLegal Proceedings.

In 2007, we
invested U.S.$8 million in a new effluent treatment system for the Licancel Mill. However, we can offer no assurance that the Licancel Mill will be able to operate without further interruptions. Any future suspension of operations at the Licancel
Mill may adversely affect our business, financial condition, results of operations and cash flows. See Item 8. Financial InformationLegal Proceedings and Item 4. Information on the CompanyDescription of
BusinessPulpPulp millsChileLicancel Mill.

We are subject to legal proceedings related to our mills, which
could adversely affect our business, financial condition, results of operations and cash flows

On April 27,
2005, the National Defense Council (Consejo de Defensa del Estado), the Chilean national agency that institutes legal proceedings on behalf of the Chilean government, instituted a civil lawsuit seeking reparations, damages and indemnification from
us for environmental harm allegedly caused by the Valdivia Mill. On September 7, 2007, the National Defense Council instituted a civil lawsuit seeking reparations, damages and indemnification from us for environmental harm allegedly caused by
the Licancel Mill. The National Defense Council agreed to terminate this lawsuit pursuant to an agreement with Arauco dated January 29, 2010. However, the resolution that approved the agreement and declared the lawsuit terminated was challenged
by certain third parties. This action remains under review by the tribunal as of the date of this annual report. If the results of the Valdivia Mill lawsuit are unfavorable to us, we may be required to invest funds or take other action to repair any

environmental harm a court determines we have caused, which could materially and adversely affect our business, financial condition, results of operations and cash flows. We cannot predict the
outcome or impact of this lawsuit or when it may be resolved. See Item 8. Financial InformationLegal Proceedings.

Since the end of 2004, various criminal proceedings relating to alleged violations of several environmental laws have
been instituted in Chile in which some of our mills may be affected. We cannot predict the outcome or impact of these proceedings or when they may be resolved. While Chilean law in general provides that only individuals can be convicted in criminal
actions, as a consequence of these proceedings, certain measures may be taken that could materially and adversely affect our business, financial conditions, results of operations and cash flows. An exception to this rule is Chilean Law
No20,393, which was published in the Official Gazette on
December 2, 2009, and which established the criminal responsibility of legal entities for criminal offenses related to the financing of terrorism, money laundering or bribery. We do not have knowledge of any fact that could result in such
criminal responsibility for the Company. See Item 8. Financial InformationLegal Proceedings.

We are also
subject to certain other proceedings described in Item 8. Financial InformationLegal Proceedings. We cannot assure you that, as a result of such proceedings, our mills will be able to operate without interruption. Any such
interruption could have a material and adverse effect on our business, financial condition, results of operations and cash flows.

The
application of environmental regulations could adversely affect our ability to accomplish our development goals and adversely affect our business, financial condition, results of operations and cash flows

In each country where we have operations, we are subject to numerous national and local environmental laws concerning, among other
matters, health, the handling and disposal of waste and discharges into the air, soil and water. We have made and expect to continue to make substantial expenditures to manage our existing operations in accordance with environmental requirements.
The application of environmental laws in the countries where we have operations may affect our business strategy and our development goals, which may have an adverse effect on our business, financial condition, results of operations and cash flows.

Environmental requirements are a factor in the development and operation of new projects. Chilean environmental regulations
have become increasingly stringent in recent years, particularly in connection with the approval of new projects, and this trend is likely to continue. The implementation of these environmental policies in Chile will affect various aspects of our
operations, but the effect on our operations and the outcome of any regulatory review or proceedings is uncertain. Environmental concerns and enforcement matters also attract public interest and, therefore, may be subject to political considerations
that are beyond our control.

Since 2004, we have been subject to a number of environmental administrative and judicial
proceedings in Chile, including proceedings related to the Valdivia Mill, the Arauco Mill, the Nueva Aldea Complex, a forestry-industrial complex in the Eighth Region of Chile, and the Licancel Mill. As a result of these proceedings, we have been
subject to fines and sanctions, and we may be subject to fines, injunctions or other sanctions in the future. Additional proceedings, enforcement actions or claims related to environmental requirements or impacts may also be brought against us. Any
such proceedings or claims may have an adverse effect on our business, financial condition, results of operations and cash flows. See Item 4. Information on the CompanyDescription of the BusinessPulpChile,
Item 8. Financial InformationLegal Proceedings.

In the future, the addition of new or more stringent
environmental requirements or changes in the application, interpretation or enforcement of existing requirements, in any country where we have operations, could result in substantially increased capital, operating or compliance costs, impose
conditions that restrict or limit our operations or otherwise adversely affect our business, financial condition, results of operations and cash flows. These changes could limit the availability of our funds for other purposes, which could adversely
affect our business, financial condition, results of operations and cash flows.

Our operations may be subject to significant interruption or prolonged suspension if any of our
facilities experience a major accident or are damaged by natural disasters, severe weather or unexpected or catastrophic events (such as earthquakes, fires, floods, tsunamis and other similar events)

On February 27, 2010, a severe earthquake, followed by a tsunami, occurred off the coast of the southern-central region of Chile,
which is an area where we maintain our industrial operations. Immediately after the earthquake, all of our production units applied their contingency plans, which involved shutting down operations and evaluating the damage caused to each facility by
the earthquake. As a result of the earthquake and subsequent tsunami, our Mutrún sawmill was severely damaged. Our other operations that were affected by the earthquake and tsunami have been reopening gradually, with the timing of such
reopenings depending on the specific conditions of the respective mill as well as external factors such as infrastructure conditions, road connectivity, power supply and public safety concerns. As of June 22, 2010, all of our operations were
operating except for line 2 of the Arauco Pulp Mill (Arauco II), which will be reopened once the damages are assessed and repaired.

The suspension of our operations in Chile resulted in a decrease in sales volumes and adverse effects on our results of operations and
cash flows; however, we have insurance covering part of these losses. Our insurance policies cover damages to our property, plant, equipment and inventories and for business interruption caused by such damages up to an amount of U.S.$650 million,
with a deductible for such damages of U.S.$3.3 million and a deductible of 21 days for business interruption. For the first quarter of 2010, we recorded a loss for damages of property, plants and equipment and inventories of approximately U.S.$27
million, net of insurance coverage. As the date of this annual report, we expect to incur additional losses as a result of the earthquake and subsequent tsunami, but we cannot determine the total amount of such losses at this time.

We cannot assure you that we will not experience further suspensions or interruptions or experience damage to our property, plant,
equipment and inventories as a result of further earthquakes, aftershocks, floods, repair and maintenance, relocation of facilities or other consequences associated with such events, which could materially and adversely affect our business,
financial condition, results of operations and cash flows.

Climate change may negatively affect our business, results of operations and
cash flows

A growing number of scientists, environmentalists, international organizations, regulators and other
commentators argue that global climate change has contributed, and will continue to contribute, to the unpredictability, frequency and severity of natural disasters (including, but not limited to, hurricanes, tornadoes, freezes, other storms and
fires) in certain parts of the world. As a result, a number of legal and regulatory measures as well as social initiatives have been introduced in different parts of the world in an effort to reduce greenhouse gas and other carbon emissions, which
some argue to be substantial contributors to global climate change. In addition, public expectations for reductions in greenhouse gas emissions could result in increased energy, transportation and raw material costs and may require us to make
additional investments in facilities and equipment. Although we cannot predict the impact of changing global climate conditions, if any, nor can we predict the impact of legal, regulatory and social responses to concerns about global climate change,
any such occurrences may negatively affect our business, financial condition, results of operations and cash flows.

Fluctuations in
market price for our products could adversely affect our financial condition, results of operations and cash flows

Prices for pulp, forestry and wood products can fluctuate significantly. The average price, on an annual basis, for Norscan bleached
softwood kraft market pulp (pulp produced in Canada and Northern Europe sold to manufacturers of paper products delivered in Northern Europe, or NBSK), which is the benchmark for softwood bleached pulp, ranged from U.S.$598.69 per metric ton in 2005
to U.S.$641.51 per metric ton in 2008. In 2009, the price of NBSK ranged from a minimum of U.S.$577.09 per metric ton to a maximum of U.S.$798.79 per metric ton. During the first quarter of 2010, the price of NBSK ranged from a minimum of
U.S.$798.63 per metric ton to a maximum of U.S.$889.08 per metric ton. As of June 22, 2010 the price of NBSK was U.S.$975.70 per metric ton. Our business, financial condition, results of operations and cash flows could be materially and
adversely affected if the price of pulp or other forestry products were to decline significantly from current levels. The prices that we are able to obtain for pulp products and, to a lesser extent, other forestry products depend on the following:

Each of these factors is beyond our control.

Worldwide competition in the markets for our products could adversely affect our business, financial condition, results of operations and cash
flows

We experience substantial worldwide competition in each of our geographical markets and in each of our product
lines. Several of our competitors are larger than we are and have greater financial and other resources, which they could use to take steps that could adversely affect our financial and competitive position. The pulp industry is sensitive to changes
in industry capacity and producer inventories, as well as to cyclical changes in the worlds economies, all of which may significantly affect selling prices and, thereby, our profitability. Increased competition could materially and adversely
affect our business, financial condition, results of operations and cash flows.

Global economic developments, and particularly economic
developments in the U.S. economy, could adversely affect our business, financial condition, results of operations and cash flows

The decrease in demand of sawn timber products due primarily to the credit crisis and the continued downturn in the real estate market in
the United States resulted in our decision to close four sawmills in 2008. As a result, in 2008 we recorded a pre-tax impairment charge totaling U.S.$32.9 million, relating to the closure of our sawmills. Additionally, during 2008 and as a result of
the impact that the credit crisis had on the Brazilian market and the reduction of the quantities to be produced by the Curitiba fiberboard panels plant, we decided to conduct an impairment analysis pursuant to which we recorded in 2008 a pre-tax
impairment charge of U.S.$32.5 million to reduce the carrying value of this plant to the estimated sales price minus selling costs. See Note 14 to our audited consolidated financial statements.

Export sales to the United States market accounted for approximately 10.3% of our sales revenues in 2009 as compared to 14.0% in 2008 and
12.0% in 2007. In addition, we placed a significant quantity of our sawn timber products in other markets, especially Asia and the Middle East, in order to avoid additional staffing adjustments in the facilities and to mitigate the economic impact
of these events in our sawn timber division. Our business, financial condition, results of operations and cash flows could be materially and adversely affected if the economic conditions in the United States and abroad continue to deteriorate, and
if we are unable to re-allocate our sawn timber products to other markets on equally beneficial terms, which could require us to recognize additional impairment charges.

We depend on free international trade as well as economic and other conditions in our principal export markets

In 2009, export sales, defined as sales out of the country where our goods were produced, accounted for approximately 76.2% of our total
sales revenues. During this period, 52.7% of our export sales were to customers in Asia, 20.3% to customers in North America, 13.4% to customers in Europe, 10.9% to customers in Central and South America and 2.7% to customers in other countries. As
a result, our results of operations and cash flows depend, to a significant degree, on economic, political and regulatory conditions in our principal export markets. Our ability to compete effectively in our export markets could be materially and
adversely affected by a number of factors beyond our control, including deterioration in macroeconomic conditions, exchange rate volatility, government subsidies, and the imposition of increased tariffs or other trade barriers. If our ability to
sell our products competitively in one or more of our principal export markets were impaired by any of these developments,

it might be difficult to re-allocate our products to other markets on equally favorable terms and our business, financial condition, results of operations and cash flows might be adversely
affected.

Disease or fire could affect our forests and manufacturing processes and, in turn, adversely affect our business, financial
condition, results of operations and cash flows

Our operations are subject to various risks affecting our forests and
manufacturing facilities, including disease and fire. Although, in the past, certain pests and diseases afflicting radiata or taeda pine plantations in other parts of the world have not significantly affected the forestry industries in Chile,
Argentina, Brazil and Uruguay, these pests or diseases may appear in Chile, Argentina, Brazil or Uruguay in the future. Although, in the past, forest fires have not significantly affected our plantations partly due to the broad geographic extension
of our plantations and the varied ages and climatic conditions of our plantations, forest fires may affect our plantations in the future. Our operations and, as a result, our business, financial condition, results of operations and cash flows could
be adversely affected if any of these risks were realized. SeeItem 4. Description of BusinessForestry ActivityForest Management.

Risks Relating to Chile

Chilean
political and economic conditions directly impact our business and the market price of our securities

At
December 31, 2009, 76.6% of our property, plant and equipment and forest assets were located in Chile, and in 2009, approximately 80.1% of our net sales were attributable to our Chilean operations. Accordingly, our business, financial
condition, results of operations and cash flows depend, to a considerable extent, upon economic conditions in Chile. Future developments in the Chilean economy could adversely affect our business, financial condition, results of operations and cash
flows and may impair our ability to proceed with our strategic plan of business. In addition, such developments may impact the market price of our securities.

The Chilean government has exercised and continues to exercise a substantial influence over many aspects of the private sector and has
changed monetary, fiscal, tax and other policies to influence the Chilean economy. We have no control over and cannot predict how government intervention and policies will affect the Chilean economy or, directly and indirectly, our operations and
revenues. Our operations and financial condition and the market price of our securities may be adversely affected by changes in policies involving exchange controls, taxation and other matters. In addition, our operations and financial condition and
the market price of our securities may be adversely affected by factors such as:



| |  |  | fluctuations in exchange rates;
| | - |  | -------------------------------



| |  |  | base interest rate fluctuations; and
| | - |  | ------------------------------------



| |  |  | other political, diplomatic, social and economic developments in or affecting Chile.
| | - |  | ------------------------------------------------------------------------------------

Chiles rates of inflation, which were 7.1% in 2008 and -1.4% in 2009, as measured by changes in the Chilean consumer price index,
may adversely affect our operations and financial condition and the market price of our securities.

Risks Relating to Argentina

The economic conditions in Argentina may adversely affect our financial condition, results of operations and cash flows

At December 31, 2009, approximately 11.7% of our property, plant and equipment and forest assets were located in
Argentina, and in 2009, approximately 11.6% of our net sales were attributable to our Argentine operations. The financial condition and results of our Argentine operations, including the ability of Alto Paraná S.A., or Alto Paraná, our
Argentine subsidiary, to raise capital, depend, to a certain extent, upon political and economic conditions prevailing in Argentina. SeeItem 4. Information on the CompanyDescription of BusinessHistory.

From 1998 to 2002, the Argentine economy experienced an economic recession marked by reduced
levels of consumption and investment and an elevated unemployment rate. The Argentine gross domestic product, or GDP, decreased by 0.8% in 2000, 4.0% in 2001 and 10.9% in 2002. Since 2003, economic indicators have shown some signs of recovery, and
the Argentine GDP increased by 8.8% in 2003, 9.0% in 2004, 9.2% in 2005, 8.5% in 2006, 8.7% in 2007 and 6.8% in 2008. In 2009, Argentinas GDP growth slowed to 0.9% as a result of the global financial crisis. The future economic, social and
political developments in Argentina, over which we have no control, could adversely affect our business, financial condition, results of operations and cash flows.

In addition, the Argentine government has exercised and continues to exercise a significant influence over many aspects of the Argentine
economy. Accordingly, the Argentine governments actions, including actions with respect to inflation, price controls, interest rates, foreign exchange controls, organized labor and taxes, have had and may continue to have a material adverse
effect on private sector entities, including our operations in Argentina.

Argentine Central Bank restrictions may impair Alto
Paranás ability to meet its obligations and transfer money abroad

We guarantee a portion of Alto
Paranás debt. We may be required to fulfill our obligation under our guarantees if the Argentine government were to restrict Alto Paranás ability to transfer funds abroad. For a description of Alto Paranás debt
which we guarantee see Item 5. Operating and Financial Review and ProspectsLiquidity and Capital Resources.

Since 2001, the Argentine government has imposed a number of monetary and currency exchange control measures, which have included the
obligation to repatriate foreign currency earned abroad and tight restrictions on transferring funds abroad, with certain exceptions for authorized transactions. Although current restrictions have not materially affected Alto Paranás
business, financial condition, results of operations and cash flows, there can be no assurance that the Central Bank of Argentina will not reverse its position and again restrict payments, which could impose material obstacles to Alto
Paranás ability to transfer money abroad and negatively affect its business, financial condition, results of operations and cash flows.

Risks Relating to Brazil

Economic
conditions in Brazil may have a direct impact on our business, financial condition, results of operations and cash flows

At December 31, 2009, approximately 11.7% of our property, plant and equipment and forest assets were located in Brazil, and in
2009, approximately 8.3% of our net sales were attributable to our Brazilian operations. During the first quarter of 2005, we acquired all of the shares of capital stock of LD Forest Products S.A. and of Placas do Paraná S.A. in Brazil, as
well as 50% of the shares of capital stock of Dynea Brasil S.A. in Brazil. In April 2010, our subsidiary Arauco do Brasil S.A. acquired the other 50% of the shares of Dynea Brasil S.A. As a result of this acquisition, we own 100% of the shares of
Dynea Brasil S.A.

In September 2007, Arauco entered into an agreement for the joint ownership of land with Stora Enso Oyj, a
Finnish-Swedish multinational corporation. Pursuant to the agreement, Arauco acquired 80% of the shares in Stora Enso Arapoti Empreendimentos Agrícolas S.A., which owns 50,000 hectares of land, including 25,000 hectares of pine and 5,000
hectares of eucalyptus plantations; 20% of the shares in Stora Enso Arapoti Indústria de Papel S.A., which owns a paper mill with an annual production capacity of 205,000 tons of light weight coated paper; and 100% of the shares of Stora Enso
Arapoti Serraria Ltda., which owns a sawmill with an annual production capacity of 150,000 cubic meters per year. In August 2009, we acquired, through our Brazilian subsidiary Placas do Paraná S.A., Tafisa Brasil S.A. (Tafisa
Brasil), which has an annual total installed capacity of 640,000 cubic meters.

As a result of the foregoing, to a
certain extent, our business, financial condition, results of operations and cash flows will be dependent on economic conditions in Brazil. SeeItem 4. Information on the CompanyDescription of BusinessHistory.

The Brazilian government has exercised, and continues to exercise, significant influence over the
Brazilian economy. Brazilian political and economic conditions have a direct impact on our business

The Brazilian
government frequently intervenes in the Brazilian economy and, occasionally, makes drastic changes in policy and regulations. The Brazilian governments actions to control inflation and other policies and regulations have often involved, among
other measures, wage and price controls, currency devaluations, capital controls and limits on imports. The business, financial condition, results of operations and cash flows of our recently acquired Brazilian subsidiaries may be adversely affected
by changes in policy or regulation involving tariffs and exchange controls, as well as by factors such as:



| |  |  | currency fluctuations;
| | - |  | ----------------------



| |  |  | inflation;
| | - |  | ----------



| |  |  | social instability;
| | - |  | -------------------



| |  |  | price instability;
| | - |  | ------------------



| |  |  | interest rates;
| | - |  | ---------------



| |  |  | liquidity of domestic capital and lending markets;
| | - |  | --------------------------------------------------



| |  |  | tax policy; and
| | - |  | ---------------



| |  |  | other political, diplomatic, social and economic developments in or affecting Brazil.
| | - |  | -------------------------------------------------------------------------------------

Inflation and efforts by the Brazilian government to combat inflation may contribute significantly to economic uncertainty in Brazil and could harm
the business of our Brazilian subsidiaries

In the past, Brazil has experienced extremely high rates of inflation;
3.1% in 2006, 4.5% in 2007, 5.9% in 2008 and 4.3% in 2009 as measured by the Brazilian consumer price index (Índice de Preços ao Consumidor-Amplo). During this period, inflation, governmental measures to combat inflation and
public speculation about possible future actions have had significant negative effects on the Brazilian economy. Future measures taken by the Brazilian government, including interest rate increases, intervention in the foreign exchange market and
actions to adjust or fix the value of the real may trigger increases in inflation, and consequently, have adverse economic impacts on our business. If Brazil experiences high inflation in the future, the business, financial condition, results
of operations and cash flows of our recently acquired Brazilian subsidiaries could suffer.

Fluctuations in the value of Brazils
currency against the value of the U.S. dollar may result in uncertainty in the Brazilian economy and the Brazilian securities market, which may adversely affect the financial condition, results of operations and cash flows of our recently acquired
Brazilian subsidiaries

The Brazilian realhas historically suffered frequent devaluation. In the past, the
Brazilian government has implemented various economic plans and exchange rate policies, including sudden devaluations, periodic mini-devaluations during which the frequency of adjustments has ranged from daily to monthly, floating exchange rate
systems, exchange controls and dual exchange rate markets. Although over long periods depreciation of the realgenerally is correlated with the differential in the inflation rate in Brazil versus the inflation rate in the United States,
depreciation over shorter periods has resulted in significant fluctuations in the exchange rate between the realand the U.S. dollar and other currencies.

The realdepreciated 34.2% against the U.S. dollar in 2009, and appreciated 4.2% during the first five months of 2010. The
exchange rate between the realand the U.S. dollar may continue to fluctuate and may rise or decline substantially from current levels.

Devaluation of the Brazilian real and currency instability could adversely affect the
ability of our Brazilian subsidiaries to meet their foreign currency obligations in the future and could result in a monetary loss relating to this indebtedness.

Risks Relating to Other Markets

Our business, earnings and prospects may be adversely affected by developments in other countries that are beyond our control

Our business, financial condition, results of operations and cash flows depend, to a large extent, on the level of economic activity,
government and foreign exchange policies and political and economic developments in our principal export markets. In 2009, approximately 94.9% of our total pulp sales and approximately 60.4% of our total sales of forestry, wood and panel products
were attributable to exports, principally to customers in Asia, the Americas and Western Europe. Our business, earnings and prospects, as well as our financial condition, results of operations, cash flows and the market price of our securities, may
be materially and adversely affected by developments in these export markets relating to inflation, interest rates, currency fluctuations, protectionism, government subsidies, price and wage controls, exchange control regulations, taxation,
expropriation, social instability or other political, economic or diplomatic developments. We have no control over these conditions and developments, which could adversely affect our business, financial condition, results of operations and cash
flows.

Developments in other emerging and developed markets may adversely affect the market price of our securities and our ability to
raise additional capital

The market price of our securities may be adversely affected by declines in the
international financial markets and world economic conditions. Chilean securities markets are, to varying degrees, influenced by economic and market conditions in other emerging and developed market countries, especially those in the United States,
China and Latin America. Although economic conditions are different in each country, investors reactions to developments in one country can affect the securities markets and the securities of issuers in other countries, including Chile.
Negative developments in the international financial markets in the future could adversely affect the market price of our securities and impair our ability to raise additional capital.

Risks Relating to Our Securities

The non-payment of funds by our subsidiaries could have a material and adverse effect on our business, financial condition, results of operations
and ability to service our debt, including our securities

Our cash flow and our ability to service debt is dependent,
in part, on the cash flow and earnings of our subsidiaries and the payment of funds by those subsidiaries to us, in the form of loans, interest, dividends or otherwise. Our subsidiaries are separate and distinct legal entities and have no
obligation, contingent or otherwise, to pay any amounts due under the terms of our securities or to make any funds available for such purpose. Furthermore, claims of creditors of our subsidiaries, including trade creditors, will have priority over
our creditors, including holders of our securities, with respect to the assets and cash flow of the subsidiaries. Our right to receive assets of any of our subsidiaries upon their liquidation or reorganization (and the consequent right of the
holders of our securities to participate in those assets) will be effectively subordinated to the claims of that subsidiarys creditors.

Changes in Chilean tax laws could lead us to redeem our securities

Under current Chilean law and regulations, payments of interest to holders of debt securities that are not residents of Chile for
purposes of Chilean taxation will, generally, be subject to Chilean withholding tax at a rate of 4.0%. Subject to certain exceptions, we will pay additional amounts (as described in Item 10. Additional InformationTaxation) so that
the amount received by the holder of securities after Chilean withholding tax will equal the amount that would have been received if no such taxes had been applicable. In the event of certain changes in Chilean tax laws requiring that we pay
additional amounts that are in excess of the additional amounts that we would owe if payments of interest on our securities were subject only to a 4.0% withholding tax, we will have the right to redeem our securities.

|Item 4. | Information on the Company
|------- | --------------------------

DESCRIPTION OF BUSINESS

We believe that, as of December 31, 2009, we were Latin Americas largest forest plantation owner, and that we are Chiles
largest exporter of forestry and wood products in terms of sales revenue. We have industrial operations in Chile, Argentina and Brazil. As of December 31, 2009, we had approximately 1.0 million hectares of plantations in Chile, Argentina,
Brazil and Uruguay. During 2009, we harvested 16.2 million cubic meters of sawlogs and pulplogs and sold 4.9 million cubic meters of wood products, including sawn timber (green and kiln-dried lumber), remanufactured wood products and
panels (plywood, medium density fiber board, or MDF, particle board, or PBO, and high density fiber board, or HB).

Based on
information published by Resource Information Systems, Inc., an independent research company for the pulp and paper industry, at December 31, 2009, we were one of the worlds largest producers of bleached and unbleached softwood kraft
market pulp in terms of production capacity, with an estimated 7.3% share of the total world production of bleached softwood kraft market pulp and a 15.7% share of the total world production of softwood kraft market unbleached pulp. Market
pulp is pulp sold to manufacturers of paper products, as opposed to pulp produced by an integrated paper producer for use in its paper production facilities. Kraft pulp is pulp produced using a chemical process.

Based on information published by Resource Information Systems, Inc., we were also one of the worlds lowest-cost producers of
softwood kraft market pulp. We believe that we are able to produce our products at a lower cost than our competitors because of the high growth rate and short harvest cycle of radiata and taeda pine compared to other commercial softwoods, the
advanced genetic and silviculture techniques we apply in our forest management, our competitive labor costs, our modern mill facilities and the proximity of our operations to Pacific coast ports.

History

Celulosa Arauco y Constitución S.A. is a corporation (sociedad anónima) organized under the laws
of Chile, and subject to the rules of the Chilean public corporations (sociedades anónimas abiertas). Our principal executive offices are located at Avenida El Golf 150,
14thFloor, Las Condes, Santiago, Chile, and our telephone
number is +56-2-461-7200.

We were formed on September 14, 1979 in a merger between Industrias de Celulosa Arauco S.A.,
or Industrias Arauco, and Celulosa Constitución S.A., or Celulosa Constitución. Our two predecessor companies were created in the late 1960s and early 1970s by Corporación de Fomento de la Producción, or Corfo, a Chilean
government development corporation, to develop forest resources, improve soil quality in former farming areas and promote employment. As part of the Chilean governments privatization program, Corfo sold Industrias Arauco to
Compañía de Petróleos de Chile S.A., or Copec, in 1977 and Celulosa Constitución to Copec in 1979. In October 2003, Copec transferred all of its gasoline- and fuel-related business assets to a new subsidiary, and changed
its legal name to Empresas Copec S.A., or Empresas Copec. SeeItem 7. Major Shareholders and Related Party TransactionsMajor Shareholders.

In 1996, we acquired Alto Paraná S.A., an Argentine company, which, at that time, owned plantations and other land in Argentina
and manufactured and sold bleached softwood kraft pulp. With this acquisition, we expanded our market opportunities outside of Chile.

In 2000, we acquired 98% of the shares of Forestal Cholguán S.A., or Cholguán, and 50% of Trupán S.A., or
Trupán, which permitted us to enter the MDF and HB markets, and in 2002, we began operations at two new MDF mills, one in Chile and one in Argentina.

In 2005, we expanded our presence in Chile, Argentina and Brazil through a series of
acquisitions that increased our land holdings and the production capacity of various sectors of our business.

On
June 30, 2006, through our subsidiaries Aserraderos Arauco S.A., Forestal Celco S.A., Bosques Arauco S.A. and Forestal Valdivia S.A., we acquired the forestry assets of Cementos Bío-Bío S.A. The acquisition represented an
investment of approximately U.S.$133.3 million. The acquired assets consisted of 21,000 hectares of pine plantations, one sawmill with an annual production capacity of approximately 250,000 cubic meters per year and a remanufacturing facility.

On September 27, 2007 we entered into an agreement for the joint ownership of land in Brazil with Stora Enso Oyj, a
Finnish-Swedish multinational corporation. Pursuant to the agreement, we acquired 80% of the shares in Stora Enso Arapoti Empreendimentos Agrícolas S.A., now Arauco Florestal Arapoti S.A., which owns 50,000 hectares of land, including 25,000
hectares of pine and 5,000 hectares of eucalyptus plantations; 20% of the shares in Stora Enso Arapoti Indústria de Papel S.A., which owns a paper mill with an annual production capacity of 205,000 tons of light weight coated paper; and 100%
of the shares of Stora Enso Arapoti Serraria Ltda., which owns a sawmill with an annual production capacity of 150,000 cubic meters per year. This alliance required an investment of U.S.$208.4 million, which was financed with our resources and
commercial bank loans.

On May 17, 2009, our subsidiary Arauco International S.A. and a subsidiary of Stora Enso Oyj
agreed through a joint venture partnership to acquire the Uruguayan subsidiaries of the Spanish Grupo Empresarial ENCE S.A., which acquisition was completed on October 16, 2009. The companies acquired by the joint venture partnership were
Eufores S.A., Celulosa y Energía Punta Pereira S.A. and Zona Franca Punta Pereira S.A. The main assets of these subsidiaries include 130,000 hectares of land, of which 73,000 have forestry plantations, 6,000 hectares under agreements with
third parties, an industrial site, the necessary environmental permits for the construction of a pulp mill, a river terminal, a chip producing mill and a nursery. The agreed value of these assets, pursuant to the aforementioned transaction, was
U.S.$335 million, of which Arauco paid 50% (or U.S.$167.5 million). SeeItem 5. Operating Financial Review and ProspectsResults of OperationsNegative Goodwill Immediately Recognized.

On August 26, 2009, our subsidiary Placas do Paraná S.A. acquired 100% of the shares of Tafisa Brasil, by means of a share
purchase agreement executed among SCS Beheer, B.V., Tafiber  Tableros de Fibras Ibéricos, S.L. (each of which is a subsidiary of Sonae Indústria, SGPS, S.A.) and Placas do Paraná S.A. Pursuant to the transaction, we paid a
purchase price of approximately U.S.$227 million, of which approximately U.S.$165.2 million was allocated to pay the value of the shares of Tafisa Brasil, with the balance corresponding to liabilities that the acquired company maintained. The
primary asset of Tafisa Brasil (which has been renamed Arauco do Brasil S.A.) is a panel production facility located in the city of Pien, Brazil, which is in the state of Paraná. The facility has an annual total installed capacity
of 640,000 cubic meters, which includes three production lines: two lines producing medium density fiberboard (MDF) and one line producing particleboard. The facility also has added-value lines to produce products for the construction and furniture
industries.

On September 27, 2009, Arauco and its subsidiary Arauco Internacional S.A., executed a series of joint
venture agreements with Stora Enso, pursuant to which Stora Enso Amsterdam B.V. agreed to transfer ownership of 100% of the shares of Stora Enso Uruguay S.A. to Forestal Cono Sur S.A., an Arauco subsidiary in Uruguay, which was subsequently renamed
Montes del Plata S.A. (Montes del Plata). As a consequence of this transaction, Arauco and Stora Enso equally control all assets that both companies own in Uruguay, which includes 74,000 hectares owned by Stora Enso (including 17,300
hectares which are already planted with forests) and 39,000 hectares owned by Arauco (of which 27,400 are already planted with forests). These assets, and those that we acquired from Grupo Empresarial ENCE, S.A. in May of 2009, have helped to secure
a strategic basis to consider the construction of a future pulp mill in Uruguay. SeeItem 5. Operating Financial Review and ProspectsResults of OperationsOther Profit (Loss).

In April 2010, our subsidiary Arauco do Brasil S.A. acquired 50% of the shares of Dynea Brasil S.A. from Dynea AS for U.S.$15 million. As
a result of this acquisition, we now own 100% of the shares of Dynea Brasil S.A.

Forestry Activity

Radiata pine grows at the fastest rates within a narrow band of latitude and under certain climatic conditions. One of Chiles main
advantages in the forestry products industry lies in the short growing cycle of its radiata pine plantations. The faster growth rate of radiata pine trees in Chile allows harvesting of pulplogs and sawlogs 16 to 18 years after planting and of high
quality sawlogs 25 years after planting. For most temperate softwood forests in the Northern Hemisphere this range is 18 to 45 years for pulplogs and 50 to 150 years for high quality sawn timber. Consequently, the Chilean forestry industry is a
relatively low cost producer, since a Chilean producer generally requires less time and a smaller area to produce the same volume of pine as its North American or European competitors, who face lower forest growth rates and higher transportation and
investment costs as a result of the larger tracts of forests necessary to produce equivalent yields of softwood. Accordingly, since the mid-1970s, we have focused our forest management toward the application of advanced genetic and silviculture
techniques to increase productivity and the quality of our plantations.

Eucalyptus, which we started planting in 1989, grows
well in the forest regions of Chile. Once planted, eucalyptus trees require no further forest management (other than fire control and reduction of weeds) until harvest. The average harvest cycle of eucalyptus plantations is approximately 12 years.
Once cut, eucalyptus regrows and it is only after two additional harvest rotations of approximately 12 years each that it becomes necessary to replant.

Throughout our history, we have demonstrated a continued commitment to the improvement of our forest management policies. In particular,
we have adopted environmentally sensitive policies towards our holdings of native forests, which are protected and preserved in their entirety. Our products come from our established plantations only; we do not sell any products derived from our
native forests. We conduct our forestry operations in accordance with current legislative and environmental sustainability standards. Certain of our subsidiaries have received various environmental certifications as of the date of this annual
report, which include, but are not limited to the following:



| |  |  | Sustainable Forest Management Certification: the Chilean certification of sustainable forest management, as determined since 2004 by the PEFC

Forest Plantations

At December 31, 2009, our planted forests consisted of 80% radiata and taeda pine and 20% mainly of eucalyptus. Radiata and taeda
pine have a rapid growth rate and a short harvest cycle compared to other commercial softwoods. Radiata and taeda pine are sufficiently versatile for both the production of forestry and wood products and the production of long fiber pulp for sale to
manufacturers of paper and packaging.

We seek to manage our forestry resources in a way that ensures that the annual growth
of our forest is equal to or greater than the volume of resources harvested each year. In 2009, Arauco planted a total of 47,094 hectares and harvested a total of 38,966 hectares in Chile, Argentina, Brazil and Uruguay (which includes 50% of the
total land owned in Uruguay by our joint venture, Montes del Plata). We believe that we will reach a long-term sustainable equilibrium within the next five years, with annual harvests and plantations of approximately 58,000 hectares.

Our planted radiata pine forests are located in central and southern Chile, and most are located in close proximity to our major
production facilities and to port facilities. The majority of our radiata pine is less than 16 years old.

At
December 31, 2009, our aggregate radiata pine holdings comprised approximately 43% of all Chilean radiata pine plantations, making us the countrys largest radiata pine plantation owner according to the Chilean Forestry Institute.At December 31, 2009, we owned approximately 1.1 million hectares of land in Chile, of which 0.7 million hectares are forest plantations.

At December 31, 2009, we owned 257,722 hectares of forest and other land in Argentina, 126,616 hectares of forest and other land in
Brazil and 126,786 hectares of forest and other land that our joint venture Montes de Plata owns in Uruguay. Of the total land we own in these three countries, approximately 179,621 hectares of land is planted with taeda pine and elliotti pine, a
species of softwood that has a growth rate similar to that of radiata pine. The balance includes plantations of other species of trees, land to be planted, protected areas and natural forests.

Land Acquisition and Afforestation

Our total land assets have increased from fewer than 170,000 hectares in 1980 to 1,610,970 hectares at December 31, 2009. That number
does not include 16,487 hectares owned by third parties or the assets owned by Forestal Río Grande S.A. as to which we have harvesting rights. In the five years ending December 31, 2009, we purchased 249,464 hectares of land, of which
43,841 hectares were purchased in Chile, 21,648 in Argentina, 86,738 in Brazil and 97,237 in Uruguay.

We expect to acquire
additional land in Argentina, Uruguay (through our joint venture, Montes del Plata) and Brazil, and to a lesser extent in Chile if we are presented with the opportunity to do so at a desired price or location. There can be no assurance that we would
be able to acquire land at the desired price or location.

We plan to continue our policy of supplementing our pulplog
production with purchases from domestic third parties. We believe that this policy is economically efficient, given the significant quantities of pulplog available from third parties and our increasing proportion of sawlogs yielded from our
plantations. We believe that the aggregate of our existing plantations, land currently held by us that we intend to afforest and the third-party purchases we make in the ordinary course of our business will be sufficient to satisfy our anticipated
future demand for sawlogs and pulplogs.

Chile

On January 6, 2005, through our subsidiary Forestal Valdivia S.A., we acquired 80% of Forestal Los Lagos S.A., which represented an
investment of U.S.$21.4 million and included 9,234 hectares of land planted with eucalyptus in the Fourteenth Region of Chile.

On June 30, 2006, through our subsidiaries Aserraderos Arauco S.A., Forestal Celco S.A., Bosques Arauco S.A. and Forestal Valdivia
S.A., we acquired the forestry assets of Cementos Bío-Bío S.A. The acquisition represented an investment of approximately U.S.$133.3 million. The acquired assets consist of 21,000 hectares of pine plantations, one sawmill with an
annual production capacity of approximately 250,000 cubic meters per year and a remanufacturing facility.

On October 11, 2006, the Bío Bío Investment Fund, a Chilean fund in which
a group of Chilean insurance companies and other private investors participate, acquired the assets of Forestal Bío-Bío S.A. for U.S.$346 million, which included approximately 40,000 hectares of plantations. On that same date, Arauco
entered into certain agreements with the Bío Bío Investment Fund pursuant to which Arauco became the administrator and exclusive buyer of these forestry assets. Arauco receives an annual fee for the administration of the forests.
Araucos obligations under these agreements include the purchase of the funds forestry assets over a seven-year term beginning in 2006 and the purchase of the funds supply of timber during the same period. Arauco will pay a total of
U.S.$461.6 million for the purchase of the funds forestry assets and timber supply over such seven-year term.

In
January 2007, the Bío Bío Investment Fund transferred all of its assets and financial debt to Forestal Río Grande S.A., its newly created subsidiary. At the same time, the Bío Bío Investment Fund assigned all the
administration and supply agreements it had entered into with Arauco to Forestal Río Grande S.A. Arauco has determined that Forestal Río Grande S.A. is a variable interest entity of which Arauco is the primary beneficiary. As a result,
commencing on October 11, 2006, Arauco consolidates the assets and liabilities of Forestal Río Grande S.A. The indebtedness of Forestal Río Grande S.A. is neither secured by Arauco nor is Arauco liable for such indebtedness. See
Note 1(c) to our audited consolidated financial statements.

In January 2007, through its subsidiary Bosques Arauco S.A.,
Arauco acquired 5,105 hectares of radiata pine plantation (excluding land) from Forestal Anchile Ltda. This acquisition represented an investment of approximately U.S.$43.6 million.

In July 2008, through its subsidiary Forestal Valdivia S.A., Arauco acquired U.S.$14 million worth of plantations from Lafarge Chile S.A.

Argentina

In October 2005, through our Argentine subsidiary Industrias Forestales S.A., we acquired from Louis Dreyfus S.A.S. 100% of the stock of
Ecoboard S.A.I.F. and Louis Dreyfus S.A.I.F. (subsequently renamed Ecoresine S.A.) in Argentina and, indirectly as a result of that purchase, 100% of the stock of Caif S.A. and LD Manufacturing S.A. (subsequently renamed Faplac S.A.) and 60% of the
stock of Flooring S.A. As a result of these acquisitions, we own another 8,000 hectares of plantations in Argentina.

In
November 2006, through its subsidiary Arauco Internacional S.A., Arauco acquired La Señora del Milagro S.R.L. (subsequently renamed Forestal Nuestra Señora del Carmen S.A.), an Argentine forestry company, which owns approximately 4,000
hectares of land in Argentina, for U.S. $5.4 million.

In September 2007, Faplac S.A acquired 40% of the stock of Flooring
S.A., from Fantoni SpA for U.S.$1.5 million.

In March 2008, Ecoboard SAIF, Ecoresine S.A. and CAIF S.A. merged with
Industrias Forestales S.A.

In March 2008, Faplac S.A. acquired 20% of the stock of Savitar S.A. and El Oasis S.A., for
U.S.$2.2 million, both Argentine forestry companies and owners of about 10,000 hectares of land.

In December 2008, Alto
Paraná S.A. acquired 99.99% of the stock of the Brazilian company Lucchese Empreendimentos e Participacoes Ltda., which was subsequently renamed Empreendimientos Santa Cruz S.A. and capitalized up to U.S.$29 million.

Brazil

In March 2005, through our Brazilian subsidiary Arauco do Brasil Ltda., we acquired from Louis Dreyfus S.A.S. 100% of the stock of LD
Forest Products S.A. in Brazil and, indirectly as a result of that purchase, 100% of the stock of Placas do Paraná S.A. and 50% of the stock of Dynea Brasil S.A. As a result of these acquisitions, we acquired 25,800 hectares of plantations in
Brazil.

In August 2006, through our subsidiary Arauco Forest Brasil S.A., we acquired from the
Marchiori Group certain forestry land in Brazil. This investment of U.S.$39.6 million includes 14,715 hectares of land and plantations, mostly consisting of elliotti pine.

On September 27, 2007 Arauco entered into an agreement for the joint ownership of land in Brazil with Stora Enso Oyj, a
Finnish-Swedish multinational corporation. Pursuant to the agreement, Arauco acquired 80% of the shares in Stora Enso Arapoti Empreendimentos Agrícolas S.A., now Arauco Florestal Arapoti S.A., which owns 50,000 hectares of land, including
25,000 hectares of pine and 5,000 hectares of eucalyptus plantations; 20% of the shares in Stora Enso Arapoti Indústria de Papel S.A., which owns a paper mill with an annual production capacity of 205,000 tons of light weight coated paper;
and 100% of the shares of Stora Enso Arapoti Serraria Ltda., which owns a sawmill with an annual production capacity of 150,000 cubic meters per year. This alliance required an investment of U.S.$208.4 million, which was financed with Araucos
resources and commercial bank loans.

Uruguay

On May 17, 2009, our subsidiary Arauco International S.A. and a subsidiary of Stora Enso Oyj agreed through a joint venture
partnership to acquire the Uruguayan subsidiaries of the Spanish Grupo Empresarial ENCE S.A. The companies acquired pursuant to this transaction were Eufores S.A., Celulosa y Energía Punta Pereira S.A. and Zona Franca Punta Pereira S.A. This
acquisition was completed on October 16, 2009. The main assets of these subsidiaries include 130,000 hectares of land, of which 73,000 have forestry plantations, 6,000 hectares under agreements with third parties, one industrial site, the
necessary environmental permits for the construction of a pulp mill, a river terminal, one chip producing mill and one nursery. The aggregate value of the assets acquired as a result of this transaction was U.S.$335 million, of which Arauco paid 50%
(or approximately U.S.$167.5 million).

On September 27, 2009, Arauco and its subsidiary Arauco Internacional S.A.,
executed a series of joint venture agreements with Stora Enso, pursuant to which Stora Enso Amsterdam B.V. agreed to transfer ownership of 100% of the shares of Stora Enso Uruguay S.A. to Forestal Cono Sur S.A., an Arauco subsidiary in Uruguay,
which was subsequently renamed Montes del Plata S.A. As a result of this transaction, Arauco and Stora Enso equally control all assets that both companies own in Uruguay, which includes 74,000 hectares owned by Stora Enso (including 17,300 hectares
which are already planted with forests) and 39,000 hectares owned by Arauco (of which 27,400 are already planted with forests). These assets, and those that we acquired from Grupo Empresarial ENCE, S.A. in October of 2009, have helped to secure a
strategic basis to consider the construction of a future pulp mill in Uruguay. For more information seeItem 5.Operating Financial Review and ProspectsResults of OperationsNegative Goodwill Immediately Recognized and
Other Profit (Loss).

Forest Management

For our pine plantations, our forestry management activities seek to increase sawlogs through advanced genetic techniques, planting and
site preparation procedures, thinning and pruning. Managed forests can produce trees of larger diameter and, if pruned, a higher proportion of clear wood, which generally commands a higher price than knotted wood. Although some land is not suitable
for the production of pruned logs, at December 31, 2009, over 66% of our pine forests in Chile were designed for clear wood production.

For our eucalyptus plantations, our forestry management activities seek to increase the amount of fiber production per hectare through
advanced genetic techniques and planting and site preparation procedures. Eucalyptus is more expensive to plant than pine; however, after planting, eucalyptus requires minimal forest management, yields more fiber per hectare and has a shorter growth
cycle and greater wood density than pine, resulting in a greater amount of pulp production per hectare.

As of
December 31, 2009, we had eight nurseries in Chile, Argentina and Brazil, in which we grow seedlings using seeds and using cuttings from genetically selected trees. To achieve higher quality trees and an increased growth rate, we apply strict
selection criteria to the trees from which seedlings are produced. We then plant the seedlings manually. Depending upon the species of tree to be planted and the nutrient and physical characteristics of the soil, we may also undertake a certain
amount of ground preparation before planting. Our other principal forest activities are thinning, pruning and harvesting.

##### Table of Contents

Thinning, or culling inferior trees from the plantation, occurs in the following two stages:



| |  |  | Thinning to waste. Some thinned trees are chipped and used in pulp production. Thinning to waste occurs after four to six years and results in
an average reduction of the number of trees per hectare from 1,250 to approximately 700.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Commercial thinning. Thinned trees are used in pulp production or, depending on the quality of the particular land, as sawlogs. Commercial
thinning occurs at 10 to 12 years and results in an average reduction of the number of trees per hectare from 700 to approximately 450.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This high level of thinning benefits Arauco for the following reasons:



| |  |  | the cost of planting is relatively low,
| | - |  | ---------------------------------------



| |  |  | the higher number of young trees provide each other with natural protection from the elements, and
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | the high degree of selection that thinning makes possible leaves only the highest quality trees to be harvested.
| | - |  | ----------------------------------------------------------------------------------------------------------------

Pruning involves removing branches, the source of knots, which are the main defect in sawn timber. Pruning results in a high-quality
clearwood sawlog of 5.3 meters from each tree, and is conducted three times:



| |  |  | at the time of the first thinning,
| | - |  | ----------------------------------



| |  |  | two years later, when trees are six to eight years old, and
| | - |  | -----------------------------------------------------------



| |  |  | one year later, when trees are seven to nine years old.
| | - |  | -------------------------------------------------------

Our eucalyptus plantations are neither thinned nor pruned.

Harvesting timber involves felling trees, removing branches from the logs, cutting the logs into appropriate sections and loading the
logs onto trucks for transport to sawmills, panel mills, pulp mills or ports for direct export. We use the lower section of the radiata pine, comprising the first 7 to 12 meters, in sawmills and plywood mills or it is exported as sawlogs. We use the
mid-section of the radiata pine, comprising, on average, the next 8 to 13 meters, in either sawmills or pulp mills, depending on the diameter and quality of the pine. We use the top section of the tree for pulp and MDF production.

We monitor product demand and our current inventory levels, and we match harvests from sections of our plantations that will provide the
optimal yield given our product requirements. This process involves the use of sophisticated operations research models and close communication between our different operating areas to ensure that the correct amounts of timber of the required
characteristics are supplied. We replant as soon as practicable after harvesting, with an average period between harvesting and replanting of one year.

The following table illustrates, on a hectare basis, the extent of our thinning, pruning and harvesting activities in Chile during the
periods indicated.

We manage our forest
activities, but we hire independent contractors to perform the bulk of our operations, including planting, maintenance, thinning, pruning, harvesting, transportation and access road construction. As of

##### Table of Contents

December 31, 2009, we had arrangements with more than 393 independent contractors that employed over
12,304 workers in Chile. Many of these contractors have long-standing relationships with us, but we award many contracts based on competitive bids. We believe that our arrangements with independent contractors provide greater flexibility and
efficiency than performing these activities directly.

Our plantations are interspersed with native forest and farmland, and,
as a result, they are naturally protected against the spread of certain diseases. In addition, our subsidiary Investigaciones Forestales Bioforest S.A., or Bioforest, has developed strategies to protect our forests from pests and
diseases. During the last five years, radiata pine plantations have been affected by two health problems in particular: 1) the sirex noctilio, a wasp which attacks stressed trees, has caused a natural selection for thinning and 2) the disease
produced by phytophthora pinifolia has reduced the growth rate of certain trees. To mitigate the effects of the sirex noctilio, Bioforest has implemented a biological control program under which it has released into the affected
forests natural enemies of the sirex noctilio, including the nematode, the beddingia siricidicola and the parasitoid ibalia leucospoide. To control the spread of phytophthora pinifolia, Bioforest has begun
genetically engineering our trees to be more tolerant to the disease and has also begun dispersing in our forests a fertilizer that further promotes resistance. For more information regarding certain risks to our forests presented by disease, seeItem 3. Key InformationRisk FactorsDisease or fire could affect our forests and manufacturing processes and, in turn, adversely affect our business, financial condition, results of operation and cash flows.

We operate an extensive fire control organization that interacts with the fire control organizations of other forestry companies to
ensure that any fire damage to our forests is minimal. The operation primarily consists of a system of spotter towers, manned 24 hours a day during the summer months, from which spotters report the direction of any fire observed to a central command
post, where the fires exact location is determined and an appropriate ground and/or aerial response is formulated. Over the last five years, this system has limited fire damage to our forests to an average of 0.2% of the plantations per year.

Forest Production

We harvested 16.2 million cubic meters of logs during the year ended December 31, 2009, consisting of 7.6 million cubic
meters of sawlogs, 7.0 million cubic meters of radiata pine pulplogs and 1.6 million cubic meters of eucalyptus pulplogs and other logs. We did not export any pulplogs during 2009 because substantially all of the pulplogs from our forests
were used in our pulp or panel mills. During 2009, our sawmills and panel mills used 6.3 million cubic meters of sawlogs, and no sawlogs were exported. We also sold 1.2 million cubic meters of sawlogs to unaffiliated domestic sawmills
during 2009.

A log merchandising facility located at the same site as our Horcones I and Horcones II Sawmills optimizes, cuts
and classifies wood destined for our plywood facility, sawmills or pulp mills with an annual processing capacity of 1.7 million cubic meters of logs per year. The Nueva Aldea Complex also includes a log merchandising facility, with an annual
processing capacity of 2.6 million cubic meters of logs per year.

Pulp

We believe that we were Chiles largest producer of bleached and unbleached softwood market pulp in terms of production in 2009. For
the year ended December 31, 2009, pulp sales were U.S.$1,605 million, representing 51.6% of our total sales revenue for the period.

Pulp obtained from wood fibers is used in the manufacture of printing and writing paper, hygienic and sanitary paper, board and
packaging. Whether a specific kind of pulp is suitable for a particular end use depends not only on the type of wood but also on the process used to transform the wood into pulp. Pulp made from softwoods, such as radiata pine, has long fibers and is
used to provide durability and strength to paper products. Bleached pulp is used primarily for printing and writing papers and for tissue. Unbleached pulp is used primarily for linerboard (a packaging material). Pulp made from hardwoods, such as
eucalyptus, has short fibers and is used in combination with long fiber in manufacturing paper products.

We use a chemical
process, known as the kraft process, in our pulp mills in Chile and Argentina. The raw wood is in the form of pulplogs and chips, which are combined in the production process to produce pulp. The



25

##### Table of Contents

pulplogs are first debarked and chipped. The chips are then screened, mixed and cooked with chemicals to separate the bulk of the lignin from the wood fibers. After the material is screened and
washed, it is then passed to high-density tanks. For bleached pulp, the next step is a five-stage bleaching process using chemicals, primarily chlorine dioxide. At all of our pulp mills, the bleaching process is preceded by an oxygen delignification
stage. Then, the fibers are subjected to a final stage where the sheets are formed and subsequently dried and baled for transport to customers. The lignin and bark produced during this process is used to fuel the boilers that produce steam,
providing heat and generating electricity for the mill. Our bleached pulp is bleached to a 90+ brightness level, as measured by the ISO test procedure, which is one of the industrys measurement methods.

Pulp Mills

At
December 31, 2009, we owned and operated five pulp mills in Chile and one in Argentina, with an aggregate installed annual production capacity of approximately 3.2 million metric tons. Our six pulp mills produced 2.6 million metric
tons of bleached pulp and 0.4 million metric tons of unbleached pulp in 2009.

All of our pulp mills in Chile
except for the Nueva Aldea Mill and the Licancel Mill are ISO 9001:2000 and ISO14001:2004 certified. The Nueva Aldea Mill and the Licancel Mill were certified ISO 9001:2008 and ISO 14001:2004 in February 2010. The Alto Paraná Mill in
Argentina is certified under ISO 9001:2000 and ISO14001:2004. No seasonal factors affect plant utilization, and the pulp mills generally run at full capacity throughout the year, with eight to ten days of maintenance scheduled every 12 months.

The following table sets out bleached and unbleached kraft pulp production by plant for each of the years indicated.

Chile

Arauco I.Arauco I, which was completed in 1972, is located at the Arauco Mill in the heart of a group of our radiata pine
plantations in the Eighth Region of Chile. Arauco I produces elementary chlorine-free pulp, which does not use chlorine gas. Elementary chlorine-free pulp is also produced by a significant portion of our competitors in each of the worlds major
pulp producing regions. The installed annual production capacity of Arauco I is approximately 290,000 metric tons of eucalyptus and pine bleached kraft pulp.

Arauco II.Also located at the Arauco Mill, Arauco II was completed in 1991. Arauco IIs pulping process is fundamentally the
same as that of Arauco I, but it includes technological improvements in its production

process and environmental design. Arauco II is also equipped to produce elementary chlorine-free pulp. The installed annual production capacity of Arauco II is approximately 500,000 metric tons
of pine bleached kraft pulp.

As a consequence of the earthquake that occurred in Chile on February 27, 2010, the
operations of Arauco II were temporarily suspended and will be reopened once the damages are assessed and repaired.

Constitución Mill. The Constitución Mill is located in the heart of a group of our radiata pine forests in the
Seventh Region of Chile. As of December 31, 2009, the Constitución Mill was the largest unbleached softwood market pulp mill in the world, with an installed annual production capacity of approximately 355,000 metric tons. In February
2006, the COREMA of the Seventh Region of Chile approved an environmental impact study for the construction of a new pipeline for the Constitución Mill, which commenced operations in February 2007. The Constitución Mill is equipped to
produce elementary chlorine-free pulp.

Licancel Mill.We acquired the Licancel Mill in September 1999. It is located
in Licantén, which is 250 kilometers south of Santiago. The mill has an installed annual production capacity of approximately 140,000 metric tons of eucalyptus kraft pulp and pine bleached and unbleached kraft pulp. The Licancel Mill is
equipped to produce elementary chlorine-free pulp.

Beginning in June 2007, our operations at the Licancel Mill became subject
to environmental scrutiny by Chilean environmental regulators and the public, which arose in connection with the death of fish in the Mataquito River, approximately 15 kilometers downstream of the mill. As a result, Chilean authorities, including
the health authorities and the Superintendencia de Servicios Sanitarios(Sanitary Services Superintendency), required that we suspend activities at the Licancel Mill and that we suspend any further discharges into the river. We estimate that
the suspension of operations at the Licancel Mill resulted in a total loss of profits of approximately U.S.$24 million. Several administrative and judicial proceedings have been commenced regarding the events at the Licancel Mill and the death of
fish at the Mataquito River. The mill resumed operations during January 2008. For further details in respect of the proceedings related to the 2007 suspension of operations at the Licancel Mill, see Item 8. Financial InformationLegal
Proceedings.

In 2007, we invested U.S.$8 million in a new effluent treatment system for the Licancel Mill. However, we
can offer no assurance that the Licancel Mill will be able to operate without further interruptions. Any future suspension of operations at the Licancel Mill may adversely affect our business, financial condition, results of operations and cash
flows. See Item 3. Environmental concerns led us to suspend our operations at the Licancel Mill, which adversely affected our business, financial condition, results of operations and cash flows and Item 8. Financial Information-
Legal Proceedings.

Valdivia Mill. We completed construction of the Valdivia Mill during the first quarter of
2004 and commenced operations in February 2004. The Valdivia Mill is located in Fourteenth Region of Chile (which was previously part of the Tenth Region of Chile), an area with significant radiata pine and eucalyptus plantations. The Valdivia Mill
has an installed potential annual production capacity of approximately 550,000 metric tons of bleached pulp, consisting of softwood pulp and eucalyptus pulp. The Valdivia Mill is equipped to produce elementary chlorine-free pulp.

The Valdivia Mill has been subject to legal and administrative proceedings by the Chilean environmental regulators. Primarily, it has
been alleged that the Valdivia Mills operations impacted the nearby Carlos Anwandter Nature Sanctuary and contributed to the migration and death of black-neck swans in an area downstream from the mill on the Cruces River. For a discussion of
the administrative and litigation proceedings in which we have been involved as a result of our operations at the Valdivia Mill, see Item 8. Financial InformationLegal Proceedings.

On June 16, 2009, we submitted to the COREMA a request to increase our production at the Valdivia Mill by 20% from 550,000 metric
tons to 660,000 metric tons per year, which request was rejected on July 20, 2009. Consequently, on May 28, 2010, we presented an environmental impact declaration to the COREMA pursuant to which we repeated our request to increase the
production of the Valdivia Mill from 550,000 metric tons to 660,000 metric tons per year. As of the date of this annual report, this environmental impact declaration remains under the review of the COREMA.

Nueva Aldea Mill. Located in the Eighth Region of Chile, this mill was completed in
2006 and currently has a production capacity of 1,027,000 metric tons per year, half of which is for the production of pine bleached kraft pulp and the other half of which is for the production of eucalyptus bleached kraft pulp. The Nueva Aldea Mill
is equipped to produce elementary chlorine-free pulp.

On February 20, 2006, the COREMA of the Eighth Region of Chile
approved the environmental impact study for the construction and operation of the Nueva Aldea Mill Pipeline, which will permit the mill to discharge certain liquid effluents into the ocean. The Nueva Aldea Mill Pipeline commenced its operations in
the first quarter of 2010. However, as result of damages to the pipeline caused by the earthquake that occurred in Chile on February 27, 2010, we decided to temporarily suspend our use of the pipeline. As a result, the Nueva Aldea Mill is
currently discharging its effluents in the same place in which the mills wastewaters were discharged prior to our use of the pipeline.

On February 9, 2009, COREMA approved our request to increase the Nueva Aldea Mills production to 20% above the previously
authorized level, which was 856,000 metric tons per year. The COREMA determined that it was not necessary for us to present an environmental impact study in connection with our request for increased production. As a result, our total annual
authorized production capacity has been increased to 1,030,000 metric tons. Furthermore, on October 7, 2009 we presented an environmental impact declaration requesting an additional increase in the production capacity of the Nueva Aldea Mill
from 1,030,000 metric tons to 1,200,000 metric tons per year. The COREMA approved this request on February 4, 2010. As of the date of this annual report, plans to carry out this increase in production capacity are underway.

Argentina

Alto Paraná Mill. Alto Paranás softwood pulp mill is located in the Province of Misiones, a region whose soil
and climate are favorable for the rapid growth of pine trees. The Alto Paraná Mill is the only bleached softwood kraft market pulp facility in Argentina. The mill has an installed annual production capacity of approximately 350,000 tons of
pulp, of which approximately 68% is bleached softwood pulp, currently representing almost all of the total bleached softwood pulp production capacity in Argentina, and approximately 32% is fluff pulp.

Production Costs

Based on information published by Resource Information Systems, Inc., our cash costs for softwood pulp production are significantly lower
than the average costs of market pulp producers in Canada, the United States and Scandinavia, particularly with respect to timber and energy costs. While our modern facilities result in depreciation exceeding some of such Northern Hemisphere
producers, our costs are still significantly lower than the average costs of our Northern Hemisphere competitors, on a total delivered cost basis. The following table compares our costs for the production of bleached softwood kraft market pulp to
the average costs of market pulp producers in selected regions in the Northern Hemisphere for the year ended December 31, 2009.

Arauco.

Sales

The total production of bleached kraft market pulp in the global market during the year ended December 31, 2009 was approximately
51.5 million metric tons. Based on information published by Resource Information Systems, Inc., we believe that our production represented 5.0% of this market in 2009. During the year ended December 31, 2009, we sold approximately 95.1% of
our bleached pulp in our export markets, principally to customers in Asia and Western Europe.

Integrated manufacturers
dominate the world production of unbleached softwood pulp, which leaves non-integrated companies that sell market pulp, like us, with only a small percentage of total production. Market pulp is pulp sold to manufacturers of paper
products, as opposed to pulp produced by an integrated paper producer for use in its paper production facilities. With a total world production of unbleached softwood kraft pulp of 2.3 million metric tons for 2009, according to Resource
Information Systems, Inc., our Constitución Mill was the worlds largest single producer of unbleached softwood market pulp, with 15.7% of the total market in 2009. During the year ended December 31, 2009, approximately 93.6% of our
total unbleached market pulp sales consisted of export sales. While for the last five years Asia has been our principal export market for unbleached market pulp, we continually seek niche markets for our products in Western Europe and the United
States. Historically, our sales in the Chilean market have been less than 4.0% of our total unbleached pulp sales revenue.

The following table sets forth, by region, the sales volumes of bleached and unbleached pulp for the years indicated.

While there are many grades and varieties, pulp is a
commodity that is marketed primarily on the basis of price and service. In marketing our pulp, we seek to establish long-term relationships with non-integrated end users of pulp by providing a competitively priced, high-quality, consistent product
and excellent service. The consistency of our pulp derives from our high-quality mills and our use of a single species of tree, in contrast to pulp producers in some of the worlds major softwood pulp producing regions that mix different
species, depending on availability and seasonality. Our bleached pulp is marketed under the brand names Arauco and Alto Paraná, and our unbleached pulp is marketed under the brand name Celco.

Prices for bleached softwood kraft market pulp produced from radiata pine generally fluctuate depending on prevailing world prices, which
historically have been cyclical. The fluctuations generally depend on worldwide demand, world production capacity, business strategies adopted by major forestry, pulp and paper producers and the availability of substitutes. SeeItem 5.

In accordance with
customary pulp market practice, we do not have long-term sales contracts with our customers (except for in a few limited cases); rather we maintain long-standing relationships with our customers with whom we periodically reach agreements on specific
volumes and prices. We have a diversified customer base located throughout the world and totaling, as of December 31, 2009, more than 40 clients. As of December 31, 2009, we employed more than 15 sales agents to represent us in more than
30 countries. We manage this worldwide sales network from our headquarters in Chile.

Plywood and Fiberboard Panels

Our panel products consist of plywood and fiberboard panels. At December 31, 2009, we owned two plywood mills and one HB-MDF mill in
Chile, one MDF mill and one PBO mill in Argentina, and one MDF mill, one PBO mill and one MDF-PBO mill in Brazil. For the year ended December 31, 2009, sales of panels were U.S.$832.2 million, representing 26.7% of our total sales
revenues.

Exports, which include sales to countries other than Chile, Argentina and Brazil, accounted for 54.4% of our total
sales revenues of plywood and fiberboard panels for the year ended December 31, 2009. We sell plywood and fiberboard panels primarily to customers in North America, Europe, Brazil, Chile, Argentina and other countries in Latin America.

On March 9, 2005, we acquired from Louis Dreyfus S.A.S. 100% of the stock of LD Forest Products S.A. in Brazil and,
indirectly as a result of that purchase, 100% of the stock of Placas do Paraná S.A. and 50% of the stock of Dynea Brasil S.A. We paid an aggregate purchase price for these acquisitions of approximately U.S.$168.0 million. With these
acquisitions, we acquired an MDF mill with installed annual production capacity of approximately 250,000 cubic meters, a particleboard mill with installed annual production capacity of approximately 320,000 cubic meters, an impregnated paper mill
and a formaldehyde and resin plant.

On October 31, 2005, we acquired from Louis Dreyfus S.A.S. 100% of the stock of
Ecoboard S.A.I.F. and Louis Dreyfus S.A.I.F. in Argentina and, indirectly as a result of that purchase, 100% of the stock of CAIF S.A. and LD Manufacturing S.A. and 60% of the stock of Flooring S.A. As a result of these acquisitions, we own a
particleboard mill with installed annual production capacity of approximately 260,000 cubic meters, a chemical plant that produces resins used for the production of wood panels, and an MDF and particleboard-based wood floor mill with installed
annual production capacity of approximately two million square meters. We paid an aggregate purchase price of approximately U.S.$55.0 million for this acquisition.As discussed in Item 4. Description of BusinessHistory, we have
expanded our panel production capacity in Brazil. On August 26, 2009, we acquired Tafisa Brasil. Tafisa Brasils primary asset is a panel production facility, located in Pien, Brazil, which produces both MDF and particleboard and has an
annual total installed capacity of 640,000 cubic meters.

Aserraderos Arauco S.A.
was established in 1993 to centralize management and control production in our sawmill and remanufacturing operations. Our sawmills and remanufacturing facilities in Chile are currently operated by independent contractors that are paid sawing
service fees calculated on a fixed and variable basis depending on productivity, with price renegotiations in the event of material changes in costs or productivity. Each of our 12 independent contractors operates exclusively for us and only with
respect to one sawmill or remanufacturing facility. We believe that our arrangements with independent contractors provide us with greater flexibility and efficiency than performing such activities on our own. We operate our sawmills and
remanufacturing facilities in Argentina.

As of December 31, 2009, we had 10 sawmills in operation, eight in Chile and
two in Argentina, with aggregate installed annual processing capacity of approximately 5.38 million cubic meters of sawlogs and an aggregate installed annual production capacity of approximately 2.82 million cubic meters of lumber.
Contractors that are not related to us or to each other operate our eight sawmills in Chile. We operate our sawmills in coordination with our forestry and sales operations, since our sawn timber is generally produced in accordance with customer
specifications. All of our sawmills are located near our pine plantations.

As of December 31, 2009, we also own seven
remanufacturing facilities, six in Chile and one in Argentina, that reprocess sawn timber into remanufactured wood products, such as moldings, jams and pre-cut pieces that end users require for doors, furniture and door and window frames. These
facilities produced 289,000 cubic meters of remanufactured wood products in 2009.

During 2008, the decrease in demand of sawn
timber products, due primarily to the credit crisis and the continued downturn in the real estate market in the United States, resulted in our decision to close the following facilities (indicating the date of closure and the annual lumber
production capacity of each facility):



| |  |  | the Arapoti sawmill (closed on March 31, 2008 with an annual production capacity of 250,000 cubic meters),
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | the Lomas Coloradas sawmill (closed on August 9, 2008 with an annual production capacity of 250,000 cubic meters),
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | the Coronel sawmill (closed on November 17, 2008 with an annual production capacity of 150,000 cubic meters), and
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | the Coelemu sawmill (closed on December 30, 2008 with an annual production capacity of 80,000 cubic meters).
| | - |  | ------------------------------------------------------------------------------------------------------------

In November 2009 production at the Horcones II sawmill was suspended. However, due to favorable market conditions and in order to restore
jobs in a region that was seriously affected by the earthquake, Horcones II resumed operations June 2010 with an annual production capacity of 174,000 cubic meters.

The following is a brief description of our sawmills and remanufacturing facilities and their production capacity, as of
December 31, 2009.

cubic meters of lumber. It is also equipped with drying kilns with installed annual production capacity of approximately 320,000 cubic meters and a remanufacturing facility with installed annual
production capacity of approximately 65,000 cubic meters of remanufactured wood products.

Forestry Products

Our forestry products are sawlogs, pulplogs, posts and chips. As a result of our forest management policies and the increasing maturity of
our plantations, our plantations are yielding increasing volumes of forestry products, particularly clear wood. As the volume of clear wood has grown, we have broadened our range of forestry products. For the year ended December 31, 2009, sales
of forestry products were U.S.$89.5 million, representing 2.9% of our sales revenues for such year.

The following table sets
forth, by category, forestry product sales to unaffiliated third parties for each of the years indicated.

Sustainable Development

In June 2007, we registered three electricity co-generation power plants as projects of the Clean Development Mechanism
(CDM) within the Kyoto Protocol. The three power plants, located in Trupán, Nueva Aldea (first phase) and Nueva Aldea (second phase), generate electricity through forestry biomass (meaning forestry and wood industrial sub-products, including
the renewable resource called black liquor), which is a renewable resource, and replace fossil fuel energy from the electricity grid. In connection with the CDM in June 2007, we sold 482,129 Certified Emission Reductions (CERs or
carbon credits). With this issuance, we became the first Chilean forestry company to issue CERs through the CDM of the Kyoto Protocol. The following table presents the total amount of CERs sold by Arauco for each of the years indicated.

|CERs sold |  | 482,129                 |  | 255,592 |  | 333,067

In May 2008, we
approved the construction of a new biomass cogeneration plant with a capacity of 25 Megawatts and a power boiler with a capacity of 210 tons per hour of steam in the Horcones complex. We anticipate the plant and boiler will commence operations in
the second half of 2010. This operation will represent an investment of approximately U.S.$70 million. We expect that this operation will contribute 24 Megawatts per year of additional power to the Chilean Central Interconnected System (SIC), which
distributes electrical power throughout the Central and Southern Regions of Chile. We expect to register this new biomass power plant as a CDM project during 2010.

In January 2009, we announced plans to complete a Carbon Footprint Assessment (CFA) in order to determine the amount of carbon dioxide
stored in our wood products and, to calculate the carbon dioxide emissions resulting from our plantation business. The results of the assessment were obtained in July 2009.

In April 2009, we successfully registered a fourth CDM project: the Valdivia biomass power plant.

Competition

We experience substantial worldwide competition in each of our geographical markets and in each of our product lines.

Pulp

In
general, our competitors in the pulp market vary depending on the geographical region and variety of pulp involved. CMPC Celulosa S.A. and Fibria Cellulose S.A. are our main competitors in most geographical regions. While Fibria produces hardwood
pulp only, CMPC produces both softwood and hardwood pulp. In Asia, we also face competition from Canadian, Brazilian, Russian and Indonesian producers. In Europe, we also face competition from Brazilian, Scandinavian and American producers. Our main
competitors with respect to unbleached softwood pulp are from Canada and Russia.

Plywood and fiberboard panels

Araucos principal competitors in the plywood markets are located in the United States, Finland and Russia. In some
regions, Arauco also competes with hardwood plywood produced in China, Africa and other regions of the world.

Araucos
main competitors in the MDF market are: in Latin America, Duratex S.A., Masisa S.A. and other large South American producers; in North America, local producers such as Flakeboard Company Limited and Roseburg Forest Products Co.; in Asia, producers
from Malaysia and China, and in the Middle East, European producers.

For sales of PBO, we focus on the Latin American market,
where we compete with Duratex S.A., Masisa S.A., Berneck S.A. and Fibraplac S.A.

Wood Products

For remanufactured wood products, our main competitors are located in Chile, Brazil, and the United States. For sawn timber, our main
competitors are located in Europe, New Zealand, Canada, and Chile. Arauco believes that its operating efficiencies, competitive logistics costs, ability to serve customers with multiple specifications, geographical presence in thirty eight countries
and the versatility of its radiata and taeda pine allow it to compete effectively in the world market for wood products.

Transportation,
Storage and Distribution

To remain competitive worldwide, we ship our products to various distribution centers around the
world from which final delivery to the customer is made. Historically, we and other Chilean forestry products producers have coordinated our transportation requirements to achieve larger lots to fill specially designed forestry products ships and
thus obtain competitive freight rates.

The following are the principal Chilean ports that we use, each of which are
operational as of the date of this annual report:



| |  |  | Coronel. A private port located between Concepción and the Arauco Mill, which we constructed as a member of a consortium with five other
companies and in which we have an equity interest of 50%. We shipped approximately 27.2% of our aggregate export volume through this port in 2009;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Lirquén. A private port in Concepción in which we have an equity interest of 20.1% and through which we shipped approximately
36.5% of our aggregate export volume during 2009; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | San Vicente and Talcahuano. State-owned ports near the city of Concepción through which we shipped approximately 36.3% of our aggregate
export volume during 2009.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

The ports we use in Chile are approximately 55 kilometers from the Arauco Mill, 330
kilometers from the Constitución Mill, 390 kilometers from the Licancel Mill, 100 kilometers from the Nueva Aldea Mill, and 410 kilometers from the Valdivia Mill. We do not own pulp storage warehouses in any of these ports.

We ship pulp to various ports in Europe, North and South America and Asia and, as is customary in the pulp industry, we store some stock
in those ports. We use 11 foreign ports that have warehouse facilities available, and standard storage terms provide that we are entitled to a certain period of storage free of charge. We seek to ensure that it does not exceed the free storage
period for each shipment. At December 31, 2009, we had approximately 94,594 air dry metric tons of pulp in storage in warehouses at foreign ports.

We believe that our shipping costs are comparable to those of our international competitors, notwithstanding Chiles greater
distance from Europe, because of the proximity of our plantations and mills to the Pacific coast and the economies of scale we achieve through the volume of our exports.

In Argentina, timely and competitively priced delivery of finished products to our customers is an important factor in our ability to
compete effectively, and we ship most orders either by truck or railway almost immediately after they are produced.

In
Brazil, our efficient distribution system, which delivers finished products to almost two thousand customers in over 250 cities, many of which are separated by long distances, is a key component to our competitiveness.

Description of Property

Our principal properties consist of land and production plants and facilities, the majority of which are located in Chile. At
December 31, 2009, we owned approximately 1,099,846 hectares of land in Chile, over 735,824 hectares of which consist of forest plantations, and 637,910 hectares of land in Argentina, Brazil and Uruguay, of which 320,809 consist of forest
plantations. In addition, at December 31, 2009, we owned various plants and facilities, including five pulp mills, three panel mills, eight sawmills and six remanufacturing facilities in Chile; one pulp mill, two sawmills, one MDF mill, one PBO
mill and one remanufacturing facility in Argentina; and one MDF mill, one PBO mill and one MDF-PBO mill in Brazil. In Brazil, the Arapoti sawmill was closed on March 31, 2008. In Chile, the Lomas Coloradas sawmill, the Coronel sawmill and the
Coelemu sawmill were closed in 2008. In 2009 Horcones II was temporarily closed, with operations restarting in June 2010. In February 2010, the Mutrún sawmill was severely damaged as a result of the earthquake and is closed indefinitely.

Insurance

Consistent with industry practice, we maintain fire insurance coverage for all our Chilean forest holdings and nurseries but do not insure
against pests or disease. Depending on the age of the trees affected, our insurance covers timber loss, either at replacement cost or commercial value. In Argentina we maintain fire insurance for 8,520 hectares of timber assets located in the
Campana region, near Buenos Aires. For the rest of our Argentine operations we do not maintain fire insurance for our timber assets because we believe that the risk of damage from fire is low because Argentina receives significant amounts of
rainfall, particularly during the summer months. We do not carry fire insurance for our forests in Brazil because the risk of damage from fire does not justify the costs of carrying insurance.

We also carry insurance, consistent with industry practice, covering our production plants, facilities and equipment. This insurance
provides coverage, in the event of fire, explosion, machinery breakdown or natural disaster, which includes earthquakes and tsunamis. The insurance covers up to an amount of U.S.$650 million, which includes physical damage and 12 months of business
interruption (18 months in the case of a boiler explosion in our pulp mills), with a deductible of U.S.$3.3 million for asset damage and 21 days for business interruption. All of our insurance policies covering our forest holdings and production
plants, facilities and equipment in Chile are carried by the RSA group, Mapfre S.A., Chartis S.A. and Ace Group.

The forestry
insurance is carried by the RSA Group and Penta Security Compañía de Seguros SA. Our insurance policies for facilities and equipment in Argentina are carried by the RSA Group, Mapfre S.A., Ace Group,

##### Table of Contents

La Meridional (part of American International Group, Inc.) and the Zürich Financial Services Group, and these policies cover damage resulting from fire. Our MDF and particleboard mills in
Brazil are insured by Itaú XL Seguros Corporativos and Allianz Seguros S.A., and these policies cover fire, explosions, electrical damage, equipment damage and loss of profit.

CAPITAL EXPENDITURES

To utilize our increasing volume of forest production, we have added to, expanded and modernized our processing facilities. In 2009,
aggregate capital expenditures were U.S.$362.7 million, consisting primarily of U.S.$95.2 million in acquisitions of biological assets, U.S.$212.2 million in internal projects within our existing mills, U.S.$32.0 million in the construction of a new
biomass cogeneration plant in the Horcones Complex, U.S.$5.9 million in the construction of the Nueva Aldea Pipeline and U.S.$17.4 million in the installation of a new biomass cogeneration power plant in the Viñales sawmill. In August 2009
Arauco acquired Tafisa Brasil, an investment of U.S.$167.0 million (calculated as of the December 2009 Brazil real-U.S. Dollar exchange rate). In October 2009, through a joint venture with Stora Enso, Arauco acquired forest assets in
Uruguay. The aggregate value of the assets acquired as a result of this transaction was U.S.$335 million, of which Arauco paid 50% (or approximately U.S.$167.5 million).

These capital expenditures represent amounts accrued for purposes of our audited consolidated financial statements and do not necessarily
represent the cash cost of capital expenditures in 2009.

For the year ending December 31, 2010, we have planned capital
expenditures of approximately U.S.$650.0 million, which principally include U.S$102.4 million in acquisitions of biological assets, U.S.$289.2 million in internal projects within our existing mills, an additional U.S.$49.6 million for the biomass
cogeneration power plant in the Viñales sawmill, U.S.$58.8 million in increased production capacity at the Nueva Aldea Mill and approximately U.S.$100.0 million for property and assets damaged by the earthquake that occurred in Chile on
February 27, 2010 (which amount is almost completely covered by insurance).

GOVERNMENT REGULATION

Environment

In each
country where we have operations, we are subject to numerous national and local environmental laws, regulations, decrees and municipal ordinances concerning, among other things, health, the handling and disposal of solid and hazardous waste,
discharges into the air, soil and water and other environmental impacts. Some of these laws require us to conduct environmental impact studies of future projects or activities (or major modifications thereto). Under these laws, our operations may be
subject to specific approvals, consents and regulatory requirements, and emissions and discharges may be required to meet specific standards and limitations. We have made and will continue to make substantial expenditures to comply with such
environmental laws, regulations, decrees and ordinances.

Chile

The Chilean legislation to which we are subject includes the Chilean Environmental Law (Ley Sobre Bases Generales del Medio
Ambiente) and related regulations. The Chilean Environmental Law created the National Environmental Commission (Comisión Nacional del Medio Ambiente), or CONAMA, which includes under its organization the various Regional
Environmental Commissions (the COREMAs). CONAMA is a public agency under the supervision of the President of Chile through the Environmental Ministry (Ministro Presidente de la Comisión Nacional del Medio Ambiente). These commissions
are responsible for, among other things, coordinating existing environmental regulations and evaluating environmental impact studies or declarations of environmental impact. Under the Chilean Environmental Law, we are required to conduct
environmental impact studies or declarations of environmental impact of any future projects or activities (or their significant modifications) that may affect the environment. These and other regulations also establish procedures for private
citizens to object to the plans or studies submitted by project owners.



37

##### Table of Contents

CONAMA, the COREMA, and other governmental agencies may also participate in the oversight of
the implementation of projects in accordance with their environmental impact studies or declarations of environmental impact. Under the Chilean Environmental Law and other regulations, affected private citizens, public agencies and local authorities
can sue to enforce environmental compliance. Enforcement remedies include temporary or permanent closure of facilities and fines. The application of these environmental laws and remedies may adversely affect the manner in which we seek to implement
our business strategy and our ability to realize our strategy.

On January 26, 2010, Law
No20,417 was published in the Official Gazette. This new
law replaces the existing CONAMA and COREMA with a new set of public institutions: the Ministry of the Environment (aimed at developing national environmental policy), the Service of Environmental Evaluation (in charge of administering the
environmental assessment system) and the Superintendency of Environment (in charge of supervising and auditing environmental compliance). The creation, functioning and attributes of these new institutions are subject to the publication of
administrative decrees by the President of Chile, which have been sent to the Comptroller General of Chile for review in accordance with Chilean law. Nevertheless, certain provisions of the Law
No20,417 are already in force, including minor procedural
modifications to the Environmental Impact Evaluation System (SEIA), such as the requirement that local authorities opine on the compatibility of projects or activities submitted to the SEIA with local territorial ordinances and/or plans
and the prohibition against dividing up projects for the purpose of avoiding mandatory submission to the SEIA, among others. These decrees are expected to be published and to become effective by the end of 2010.

We recently faced, and continue to face, certain environmental proceedings in connection with certain of our pulp mills. For a
description of these proceedings, see Item 8. Financial Information Litigation Proceedings.

Argentina

Our operations in Argentina are subject to Argentine environmental legislation, including regulation by municipal, provincial
and federal governmental authorities. Argentine environmental legislation includes the requirement that water used or recovered in the production process be treated and purified before being returned to the Paraná River at the proper
temperature. All gaseous emissions must be scrubbed to ensure satisfactory levels of waste particle recovery and odor removal. Regular testing of river and air quality is used to monitor the ultimate impact of the mill on the environment.

We believe that we are currently in material compliance with all applicable local and national environmental regulations
governing our operations in Argentina.

Brazil

Our Brazilian operations are subject to environmental legislation, including municipal, regional and federal governmental laws,
regulations and licensing requirements. Law No. 6,938 establishes strict liability for environmental damage, mechanisms for enforcement of environmental standards and licensing requirements for activities that are damaging or potentially
damaging to the environment. A violation of environmental laws and regulations may result in



| |  |  | fines,
| | - |  | ------



| |  |  | partial or total suspension of activities,
| | - |  | ------------------------------------------



| |  |  | forfeiture or restriction of tax incentives or benefits, or
| | - |  | -----------------------------------------------------------



| |  |  | forfeiture or suspension of participation in credit lines with official credit establishments.
| | - |  | ----------------------------------------------------------------------------------------------

As a result, we may become liable for environmental damages caused by management of our materials, including damages caused during the transportation,
treatment and disposal of our industrial waste, even where third parties manage such activities on our behalf.

Law No. 9,605 provides that individuals or entities whose conduct or activities cause
harm to the environment are subject to criminal and administrative sanctions and are liable for any costs to repair the damages resulting from such harm. For individuals who commit environmental crimes, criminal sanctions range from fines to
imprisonment; for legal entities, criminal sanctions may include fines, partial or total suspension of activities, restrictions on participation in government contracts and, in cases of bad faith, dissolution. In addition, Law No. 9,605 also
establishes that the corporate structure of a company may be disregarded if the structure impedes the recovery for harm caused to the environment. We are not aware of any successful assertion of claims against shareholders under this provision of
Law No. 9,605.

We believe we are currently in material compliance with all applicable local and national environmental
regulations governing our operations in Brazil.

Forestry Regulation

Chile

The management and exploitation of forests in Chile is regulated by the Forests Law of 1931, as amended, and Decree-Law No. 701 of
1974, as amended. The Forests Law and Decree-Law No. 701 impose a variety of restrictions on the management and exploitation of forests. Forestry activities, including thinning, on land that is designated as preferably suited for forests or
that has natural or planted forests, are subject to management plans that require the approval of the CONAF (National Forest Service). In addition, the Forests Law and Decree-Law No. 701 impose certain standards for the prevention of forest
fires, as well as fines for the harvesting or destruction of trees and shrubs in violation of the terms of a forest management plan. We believe that we are in material compliance with the Forests Law and Decree-Law No. 701.

Law No. 20,283, published in the Official Gazette on July 30, 2008, provides a new policy for the management and conservation
of native tree forests and forest development. Its purposes are the protection, recovery and improvement of native forests in order to guarantee both forest sustainability and environmental policy. This law establishes a fund for the conservation
and sustainable management of native forests. According to the new law, owners of native forests are able to exploit them so long as they have a management plan approved by the National Forestry Corporation. Depending on the owners
approved plan, as well as other factors, the subsidy provided by the fund may vary between U.S.$200 and U.S.$400 per hectare. The law also prohibits the harvesting of native trees in certain areas and under certain conditions. Management believes
that this law will not have a material effect on our business. In compliance with applicable regulations, we have adopted environmentally sensitive policies towards our holdings of native forests, which are protected and preserved in their entirety.
Our products come from established plantations only; we do not sell any products derived from our native forests. Araucos forestry operations adhere to our international control systems, which are all in accordance with current legislative and
environmental sustainability standards. Certain of our subsidiaries have received various environmental certifications as of the date of this annual report. See Item 4. Description of BusinessForestry Activity.

All of our forest activities are ISO 14001 certified since 2001. During 2003, we obtained CERTFOR Forest Management
Certification in Chile. In 2004, PEFC (the Programme for the Endorsement of Forest Certification) undertook its first audit of our operations and confirmed that we complied with international PEFC requirements. See Item 4. Information
on the CompanyDescription of BusinessForestry Activity.

In 2005, CERTFOR certified the chain of custody of
the Arauco, Constitución, Licancel and Valdivia pulp mills and Arauco and Nueva Aldea plywood mills, pursuant to the Sustainable Forestry Management practices, which require that sources used for production are not endangered or that their
use is not otherwise prohibited. The National Regulatory Institute (Instituto Nacional de Normalización) also accredited the effluent laboratories of the Constitución and Arauco wood mills in accordance with the strict
requirements of Chilean environmental standards.

In 2009, Arauco began the pre-assessment process for FSC (Forest Stewardship
Council) forest management certification. This pre-evaluation allowed us to identify the Companys position regarding FSC principles and criteria, allowing it to better prepare for the FSCs official assessment. This pre-assessment process
covered all of Araucos forest operations in Chile and was conducted by Woodmark, a Soil Association certification body.

Argentina

The management and exploitation of forests in Argentina is regulated by National Law 13,273, National Law 25,080, National Decree 710,
Provincial Law No. 854, Provincial Law No. 3,426 and other regulations promulgated thereunder, which collectively constitute the regulatory framework. The regulatory framework imposes a variety of restrictions on the management and
exploitation of forests in Argentina. The regulatory framework regulates the replanting of land after harvesting. We believe that our Argentine operations are in material compliance with the regulatory framework.

Brazil

Environmental laws and regulations relating to the management and exploitation of forests and the protection of Brazilian plant and
wildlife govern our Brazilian forestry operations. Under this regulatory framework Brazilian authorities establish forest preservation areas and regulate replanting of forests after harvesting. We believe that our Brazilian operations are in
material compliance with the regulatory framework.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION, RESULTS OF OPERATIONS AND CASH FLOWS

The following discussion is based on and should be read in conjunction with our audited consolidated financial statements and the notes
thereto, included elsewhere in this annual report. Our consolidated financial statements are prepared in U.S. dollars in accordance with IFRS.

Overview

We derive our
sales revenue from the sale of bleached and unbleached pulp, forestry products, such as sawlogs and pulplogs, plywood and fiberboard panels and wood products, such as sawn timber and remanufactured wood products. For the year ended December 31,
2009, export sales constituted approximately 76.2% of our total sales revenue. Sales of pulp constitute the single largest component of our sales revenue. As with many commodities, pulp is subject to significant cyclical price fluctuations
determined by global supply and demand. Accordingly, our sales revenue is subject to cyclical fluctuations. World prices for forestry and wood products, which are also generally viewed as commodities, fluctuate significantly.

Although prices tend to have the most significant effect on our results of operations, sales volume and product mix, costs and exchange
rate fluctuations also can have a substantial impact on our results.

Our business , results of operations and cash flows
depend, to a large extent, on the level of economic activity, on government and foreign exchange policies and on political and economic developments in our principal export markets. In 2009, we exported our products to Asia, to North, Central and
South America, to Europe and, to a lesser extent, to Africa and the Middle East. In 2009, approximately 94.9% of our total pulp sales and approximately 60.4% of our total forestry, wood products and panel product sales were attributable to exports,
principally to customers in the Americas, Asia and Western Europe. Our business, earnings and prospects may be materially and adversely affected by developments in these export markets with respect to inflation, interest rates, currency
fluctuations, protectionism, government subsidies, price and wage controls, exchange control regulations, taxation, expropriation or social instability, as well as by political, economic or diplomatic developments.

At December 31, 2009, approximately 76.6% of our property, plant, equipment and forest assets were located in Chile, approximately
11.7% were located in Argentina and approximately 11.7% were located in Brazil. In 2009, approximately 80.1% of our consolidated sales revenue was derived from our operations in Chile, approximately 11.6% of our consolidated sales revenue was
derived from our operations in Argentina, and approximately 8.3% of our consolidated sales revenue was derived from our operations in Brazil. Accordingly, our financial condition, results of operations and cash flows depend, to a significant degree,
upon economic conditions in Chile, Argentina and Brazil.

Despite growth in the 1980s and 1990s, the Chilean economy has remained smaller than that of
certain other Latin American countries. In 2004, GDP growth was stronger than previous years, reaching 6.07% and 5.67% in 2005. The GDP grew at a slower rate in subsequent years (4.6% in 2006, 4.6% in 2007 and 3.7% in 2008). In 2009, the Chilean GDP
contracted 1.5%, mainly due to the global financial crisis.

From late 1998 to 2002, the Argentine economy went through an
economic recession marked by reduced levels of consumption and investment and an elevated unemployment rate. Argentine GDP decreased by 0.8% in 2000, 4.0% in 2001 and 10.9% in 2002. In December 2001, amid public demonstrations and the
resignation of the Argentine president, Argentina declared a suspension on payment of its foreign debt. In early 2002, the government released the Argentine peso from its one-to-one peg to the dollar and allowed the exchange rate to float, resulting
in a 49.6% devaluation of the Argentine peso from January 1, 2002 to December 31, 2002. From 2003 to 2008, economic indicators showed signs of recovery, and the Argentine GDP increased by 8.8% in 2003, 9.0% in 2004, 9.2% in 2005, 8.5% in
2006, 8.7% in 2007. In 2008 the Argentine economy growth slowed to 6.8%. Due to the global financial crisis, Argentinas GDP grew by only 0.9% in 2009. The future economic, social and political developments in Argentina, over which we have no
control, could impair Alto Paranás business, financial condition or results of operations.

Brazils GDP
decreased by an estimated 0.2% in real terms in 2009, compared to a growth rate of 4.8% in 2008 and 5.4% in 2007. This decrease is mainly explained by the financial crisis. Analyzing the previous years, the GDP decreased 0.5% in 2003, mainly due to
uncertainty regarding the election process and new economic policies to be implemented by the newly elected government of President Luis Ignacio Lula da Silva. The Brazilian real/U.S. dollar exchange rate also experienced turbulence in that
period. During 2001, the Brazilian real declined in value by 18.7% against the U.S. dollar, and in 2002, it further devalued by 52.3%, closing at R$3.5333/U.S.$1.00 on December 31, 2002. These changes were attributable primarily to
uncertainties regarding the ongoing presidential election process. Those concerns dissipated during 2003, resulting in an appreciation of the Brazilian real by 18.2% against the U.S. dollar in that year. During 2004, the Brazilian real
continued to recover against the U.S. dollar, with an 8.8% appreciation. The Brazilian real appreciated 20.7% in 2007. In 2008 and 2009, the real depreciated against the dollar by 32.2% and 34.2% respectively.

The global financial crisis has severely impacted the global paper industry, and current global economic conditions have resulted in a
decrease in demand for forest products in all markets, including Latin America. Our financial condition, results of operations and cash flows could be materially and adversely affected if the global economic conditions continue to deteriorate.
Future developments in the Chilean, Argentine and Brazilian economies may impair our ability to proceed with our strategic plan or our business, financial condition or results of operations. Our financial condition, results of operations and cash
flows could also be materially and adversely affected by changes in political, economic, regulatory or other policies of the Chilean, Argentine and Brazilian governments, which have exercised and continue to exercise substantial influence over many
aspects of the private sector in these countries, or other political or economic developments in Chile, Argentina and Brazil, as well as regulatory changes or administrative practices of Chilean authorities, over which we have no control.

Valdivia Mill Closure

Our operations at the Valdivia Mill, an industrial development in the Province of Valdivia in the Fourteenth Region of Chile (which was
previously part of the Tenth Region of Chile), have been subject to continued environmental scrutiny by Chilean environmental regulators and the Chilean public since the mill began its operations in 2004. A variety of concerns and claims have been
raised regarding potential environmental impacts in the area. Primarily, it was alleged that the mills operations impacted the nearby Carlos Anwandter Nature Sanctuary and contributed to the migration and death of black-neck swans living in
the area. In connection with an environmental administrative proceeding, environmental regulators required us to temporarily suspend operations at the Valdivia Mill for approximately one month in January 2005. We resumed operations at the mill on
February 18, 2005.

On June 8, 2005, we voluntarily suspended operations at the Valdivia Mill, until certain
technical and legal conditions could be clarified with the applicable regulatory authorities. We estimate this voluntary suspension resulted in a loss of sales of approximately U.S.$1.0 million per day and a loss of profits of approximately
U.S.$250,000 per day. Pursuant to the decision of our board of directors, based on certain clarifications provided by



41

##### Table of Contents

the Environmental Regional Commission (Comisión Regional del Medio Ambiente), or COREMA, of the Tenth Region of Chile, the mill resumed operations on August 12, 2005 at 80% of
its authorized production capacity, after 64 days of suspended operations. In order to achieve the full production capacity authorized by applicable permits, the mill had to fulfill certain new requirements established by the COREMA. On
January 18, 2008, the COREMA authorized the Valdivia Mill to return to its annual authorized production capacity of 550,000 metric tons. The mill gradually increased its production over a four-month period starting in March 2008 and reached
full capacity in June 2008. The suspension of operations at the Valdivia Mill adversely affected our business, financial condition, results of operations and cash flows. Any future suspension of operations at the Valdivia Mill or at any other of our
significant operating plants can be expected to have similar adverse effects. We offer no assurance that the Valdivia Mill will be able to operate without further interruption. See Item 4. Information on the CompanyDescription of
BusinessPulpPulp millsChileValdivia Mill and Item 8. Financial InformationLegal Proceedings.

Licancel Mill Closure

Since June 2007, our operations at the Licancel Mill, a pulp mill located in the Seventh Region of Chile, have been subject to
environmental scrutiny by Chilean environmental regulators and the public. On June 5, 2007, in connection with the death of fish in the Mataquito River, approximately 15 kilometers downstream of the mill, we decided to voluntarily suspend our
operations in the Licancel Mill as a preventive measure. In addition, Chilean authorities, including the health authorities and the Superintendencia de Servicios Sanitarios (Sanitary Services Superintendency), required that we suspend
activities at the Licancel Mill and that we suspend any further discharges into the river. On June 18, 2007, as a result of a pipe leakage in the effluent treatment system currently in place at the Licancel Mill, an estimated 50 cubic meters of
effluents reached the Mataquito River. On that same date, we decided to close the mill indefinitely and informed the Sanitary Services Superintendency of the incident. On October 3, 2007, Arauco requested that the health authority (Autoridad
Sanitaria) of the Seventh Region of Chile that it remove the suspension of activities at the Licancel mill. On October 22, 2007, the health authority of the Seventh Region of Chile removed the suspension and imposed certain conditions,
consisting primarily of the implementation of certain emergency detection and control programs and systems with which Arauco has complied. Furthermore, on November 12, 2007 the Sanitary Services Superintendency removed the suspension regarding
the release of discharges by the Licancel mill. The mill resumed operations during January 2008, using the new effluent treatment system in which we invested U.S.$8 million during 2007.

We estimate that the suspension of operations at the Licancel Mill resulted in a total loss of profits of approximately U.S.$24 million.
Several administrative and judicial proceedings have been commenced regarding the events at the Licancel Mill and the death of fish at the Mataquito River, including a civil lawsuit instituted by the National Defense Council seeking reparations,
damages and indemnification from us for environmental harm allegedly caused by the Licancel Mill, which action was subsequently terminated by agreement of the parties. However, the resolution that approved the agreement and declared the lawsuit
terminated was challenged by certain third parties. This action remains under review by the tribunal as of the date of this annual report. We can offer no assurance that the Licancel Mill will be able to operate without further interruptions. Any
future suspension of operations at the Licancel Mill may adversely affect our business, financial condition, results of operations and cash flows. See Item 8. Financial InformationLegal Proceedings and Item 4. Information on
the CompanyDescription of BusinessPulpPulp millsChileLicancel Mill.

Prices

In recent years, our sales revenue has been affected by price level volatility in the export market. The prices for each of our pulp,
panels, wood and forestry products depend on the markets in which they are sold. While prices are generally similar for a given product on a global basis, regionalized market conditions affect prices in markets such as Asia, Europe and the United
States.

Pulp Prices

Historically, world pulp prices have been subject to significant fluctuations over relatively short periods of time. Pulp prices mainly
depend on worldwide demand, world production capacity, worldwide pulp and paper inventory levels and availability of substitutes, and in general terms, are directly related to global economic growth. All of these factors are beyond our control.

Prices for bleached grades of hardwood pulp, including eucalyptus, generally follow the same cyclical pattern as prices for
Norscan Bleached Softwood Kraft market pulp, or NBSK, which is the benchmark for softwood bleached pulp. However, the latter historically has had higher prices mainly due to lower global supply. Moreover, during the last five years, the majority of
the added global pulp production capacity has been dedicated to the production of hardwood pulp, particularly eucalyptus pulp.

Prices for unbleached softwood market pulp also follow cyclical patterns related to worldwide demand. Unbleached softwood market pulp
represents about 4.3% of the total wood pulp market. The majority of such pulp is sold in Asia, and its price does not necessarily follow the cycle of prices for NBSK or Bleached Eucalyptus Kraft Pulp (BEKP).

During 2009, pulp prices for all grades increased with respect to 2008, which was mainly explained by a recovery from the global
financial crisis that began during the second half of 2008. This recovery brought as a consequence lower average inventory levels and higher demand for pulp, which are key drivers for price increases.

The market price for NBSK was U.S.$598.69 per ton at December 31, 2005, a 3.6% decrease as compared to December 31, 2004. The
price of U.S.$730.0 per ton recorded at December 31, 2006 represented an increase of 21.9% as compared to December 31, 2005. The price for NBSK was U.S.$869.30 at December 31, 2007, which represented an increase of 19.1% when compared
to December 31, 2006. The price for NBSK was U.S.$641.51 at December 31, 2008, a 26.2% decrease as compared to December 31, 2007. The price of U.S.$798.77 per ton recorded at December 31, 2009 represented an increase of 24.5% as
compared to December 31, 2008.

The market price for BEKP was U.S.$589 per ton at December 31, 2005, which
represented a 13.3% increase over the price at December 31, 2004. At December 31, 2006, the price for BEKP was U.S.$671.6 per ton, which represented a 14.0% increase over the price at December 31, 2005. The price for BEKP at
December 31,

2007 reached U.S.$775.20, which represented a 15.4% increase over the price at December 31, 2006. At December 31, 2008, the price for BEKP was U.S.$584.54, which represented a 24.6%
decrease as compared to December 31, 2007. The price for BEKP at December 31, 2009 reached U.S.$700, which represented a 19.8% increase of over the price at December 31, 2008.

The market price for unbleached kraftwood pulp, or UKP, reached U.S.$460.0 per ton at December 31, 2005, which represented a
decrease of 20.0% as compared to the price of December 31, 2004. In 2006, prices increased reaching U.S.$586.9 per ton by December 31, 2006, which represented an increase of 27.5% over the price at December 31, 2005. The price at
December 31, 2007 reached U.S.$598.5, which represented a 19.8% increase over the price at December 31, 2006. The price at December 31, 2008 dropped to U.S.$455.76, which represented a decrease of 23.8% as compared to
December 31, 2007. The price at December 31, 2009 was U.S.$603.65, which represented a 32.4% increase over the price at December 31, 2008.

Forestry, Wood Product, Plywood and Fiberboard Prices

Over the last five years, the average prices for our forestry and wood products have fluctuated significantly, reflecting the effect on
demand of global economic developments.

In spite of strong international growth and demand for wood products in 2005, prices
in the U.S. declined during the first three quarters of 2005 due to excess inventories of panel and remanufactured wood products at distributors. This trend affected the average prices for wood products during 2005. By the end of 2005, the average
prices for wood products demonstrated signs of recovery. However, the continued weakening of the construction sector in the United States caused a decrease in the price and demand for wood, particularly moldings, during 2006.

The continued weakening of the construction sector in the United States throughout 2006 caused a decrease in the price and demand for
wood, especially in moldings in that market. Along with the markets in Asia, the Middle East and Central America have been strengthening and Europe registered strong demand and prices for wood throughout 2006. The prices of plywood in the United
States and Canada slightly decreased during 2006, while the other markets maintained levels comparable to those for 2005. The demand for products directed at furniture markets in Latin America remained strong during the year, and sales of
medium-density fiberboard (MDF) panels also experimented important improvements due to the high demand in all the markets in which Arauco participates, which are concentrated in North, Central and South America.

The complications related to the United States construction and real estate markets continued throughout 2007. The construction sector
has continued to be affected by a significant stock of unsold houses, which caused construction to fall 30% in the United States during 2007. This negatively affected the sales volume of wood. Prices of moldings and wood continued to decrease. From
a commercial point of view, 2007 was marked by an increase in the demand in virtually all markets for panels. In Europe, consumer trends favoring products with a sustainable forestry management certification increased demand for the entire range of
Araucos panels. In the United States, the strong contraction of the real estate sector adversely affected the sale of MDF moldings. This was offset, however, by the strong increase in the demand for MDF boards in Latin America. In the case of
Araucos plywood panels, the demand benefited from a decrease in the supply from other manufacturers and by the highly diversified applications of these products unrelated to the construction sector.

The slowdown in the global growth markets during 2008 continued to affect the demand for timber in all markets. The construction sector
continued to decline in the United States. In particular, the construction of houses declined to a rate of approximately 550,000 houses per year by December 2008, which negatively compares with the 2 million homes built in the United States
during 2006. This decline negatively affected the sales volume and prices of wood and moldings, which reached their lowest levels during the last quarter of 2008. During most of 2008 there was a consistent demand for panels, which resulted in an
increase in price in most of the products produced by Arauco. During the latter part of 2008, however, demand lowered, which negatively affected sales volume and prices of plywood and MDF in most markets, especially in the United States and Europe.

The fiscal year 2009 was challenging for the panels business due to low demand and a weak dollar. However, Arauco was able to
sell all panels production without any plant shutdown despite the decline in demand. This was due to Araucos geographic diversification, with sales in over forty countries, and to Araucos broad product portfolio.

Our major administrative and selling expenses are wages and salaries, traffic, shipping and freight costs, insurance expenses and
commissions.

IAS 41 requires that biological assets, such as standing trees, are shown on the balance sheet at fair value.
Our forests are thus accounted for at fair value less estimated point-of sale costs at harvest, considering that the fair value of these assets can be measured reliably.

The recovery of forest plantations is based on discounted cash flow models, which means that the fair value of biological assets is
calculated using cash flows from continuing operations discounted on the basis of our sustainable forest management plans and the estimated growth of our forests. This recovery is performed on the basis of each stand identified and for each type of
tree species.

These discounted cash flows require estimates in growth, harvest, sales prices and costs. It is therefore
important that management make appropriate estimates of future levels and trends for sales and costs, as well as administer regular surveys of the forests to establish the volumes of wood available for harvesting and their current growth rates.

Our property, plant and equipment are depreciated on a straight-line basis over the remaining useful lives of the underlying
assets. However, the amount of such depreciation that relates to our fixed production assets, such as pulp mills and sawmills, is allocated to finished goods held as inventories and accumulates until charged to cost of sales when the finished goods
are sold. Forests and land are not depreciated.

Selling expenses consist primarily of per ton fees we paid to our selling
agents. Traffic, shipping and freight costs are the costs of carrying the product to the destination.

During 2008, cost of
sales increased principally due to higher cost of wood. Cost of chemicals and freight costs also increased due to a high average price in petroleum, especially during the first three quarters of the year.

During 2009, cost of sales decreased by 7.7% as a result of lower sawn timber sales volume as well as lower unit costs of wood, chemicals
and energy, reflecting Araucos stringent cost management and favorable market conditions for raw materials.

Exchange Rate Fluctuations

The Chilean peso has been subject to devaluation in the past and could be subject to significant fluctuations in the future. During 2009,
the value of the Chilean peso relative to the U.S. dollar increased approximately 25.5% in nominal terms and approximately 23.8% in real terms, based on the observed exchange rates on December 31, 2008 and December 31, 2009. The observed
exchange rate on June 22, 2010 was Ch$530.32 to U.S.$1.00. For information regarding historical rates of exchange in Chile from January 1, 2004 see Item 3. Key InformationExchange Rates.

We generally price our exports in U.S. dollars, whereas our domestic sales in Chile are priced in Chilean pesos; domestic sales in Brazil
are priced in reals and domestic sales in Argentina are priced in Argentine pesos except for pulp sales, which are priced in U.S. dollars. To the extent that the Chilean peso depreciates against the U.S. dollar, our domestic sales revenues may be
adversely affected when expressed in U.S. dollars. The same effects may occur for our domestic sales in Argentina and Brazil for products sold in each of the respective local currencies. The effect of exchange rate fluctuations is partially offset
by the fact that certain of our operating expenses are denominated in U.S. dollars (such as our freight costs and selling expenses in the form of commissions paid to our sales agents abroad) and a significant part of our indebtedness is denominated
in U.S. dollars. As of December 31, 2009, our U.S. dollar-denominated indebtedness was U.S.$ 2.8 billion. In addition, as the U.S. dollar appreciates against the local currency in any of our export markets, we must from time to time price our
sales in that local currency to compete effectively.

Critical Accounting Policies

A summary of our significant accounting policies is included in Note 1 to our audited consolidated financial statements, which are
included in this annual report. The preparation of consolidated financial statements in accordance with IFRS requires management to make subjective estimates and assumptions that affect the amounts reported. Estimates are based on historical
experience and various other assumptions that are believed to be reasonable, though actual results and timing could differ from the estimates. Management believes that the accounting policies below take into account those matters that require the
exercise of judgment, but acknowledge that different judgments could result in substantially different results. The most critical accounting policies and estimates are described below.

Property, Plant and Equipment

Property, plant and equipment are stated at cost and are depreciated using the straight-line method based on the estimated useful lives of
the assets. In estimating the useful lives (residual values are considered) we have primarily relied upon actual experience with the same or similar types of equipment and recommendations from the manufacturers. Useful lives are based on the
estimated amount of years an asset will be productive and are revised periodically to recognize potential impacts caused by new technologies, changes to maintenance procedures, changes in utilization of the equipment, and changing market prices of
new and used equipment of the same or similar types.

Property, plant and equipment assets are evaluated for possible
impairment. Factors that would indicate potential impairment may include, but are not limited to, significant decreases in the market value of a long-lived asset, a significant change in a long-lived assets physical condition and operating or
cash flow losses associated with the use of a long-lived asset. This process requires our estimate of future cash flows generated by each asset or group of assets. For any instance where this evaluation process indicates impairment, the appropriate
assets carrying values are written down to net realizable value and the amount of the write-down is charged against the results of continuing operations.

Expenditures that substantially improve and/or increase the useful life of facilities and equipment are capitalized. Other maintenance or
repair costs are charged to income as they are incurred.

Fair Value of Financial Instruments

The Company recognizes financial assets and liabilities on its balance sheet at fair value, which is the value that the Company estimates
would be attributable to such asset or liability in an arms-length transaction. As of the date of the initial recognition, the management of the Company classifies its financial assets at fair value through (i) income or (ii) collectible
credits and accounts, depending on the purpose for which the financial assets were acquired.

The fair value of financial
instruments that are not traded in an active market is determined by using valuation techniques. Arauco uses its judgment to select a variety of methods and make assumptions that are mainly based on market conditions existing at each balance sheet
date.

The doubtful provision of trade receivables is established when there is evidence that Arauco will not receive payments
under the original terms of sale. Provisions are made when the client is a party to a bankruptcy court agreement or cessation of payments, or when Arauco has exhausted all levels of recovery of debt in a reasonable time. See Note 23 to our
consolidated financial statements.

Biological Assets

The recovery of forest plantations is based on discounted cash flow models which mean that the fair value of biological assets is
calculated using cash flows from continuing operations, that is to say, on the basis of sustainable forest management plans considering the potential growth of forests. This recovery is performed on the basis of each forest stand identified and for
each type of tree species.

These discounted cash flows require estimates in growth, harvest, sales prices and costs. It is
therefore important that management make appropriate estimates of future levels and trends for sales and costs, as well as administer regular surveys of the forests to establish the volumes of wood available for harvesting and their current growth
rates. The principal considerations used to calculate the valuation of forest plantations are presented in Note 21.

Lawsuits and
Contingencies

Arauco and its subsidiaries are subject to certain ongoing lawsuits, the future effects of which need
to be estimated by the management of the Company in collaboration with its legal advisors. Arauco seeks to evaluate the reports of its legal advisors and make appropriate contingency estimates in each balance sheet based on such reports. Arauco also
makes contingency estimates and/or adjustments to prior contingency estimates upon the occurrence of material changes to the nature or underlying facts of such lawsuits.

Net Sales

Net sales decreased 16.2%, from U.S.$3,713.9 million in 2008 to U.S.$3,113.0 million in 2009, mainly as a result of decreases of
(i) 10.5% in pulp sales, (ii) 12.4% in panels sales, (iii) 19.6% in forestry products sales and (iv) 31.3% in wood products sales.

##### Table of Contents

Pulp Sales

Sales revenue of bleached and unbleached pulp decreased from U.S.$1,792.8 million in 2008 to U.S.$1,604.8 million in 2009, as a result of
a 21.9% decrease in average prices, which was partially offset by a 14.7% increase in sales volume. Sales revenue from the sale of bleached pulp decreased by 13.3% due to a 22.8% decrease in average prices, which was partially offset by a 12.3%
increase in sales volume. Sales revenue from the sale of unbleached pulp increased by 15.7%, principally due to a 33.2% increase in sales volume of unbleached pulp, which was partially offset by a reduction in overall prices of unbleached pulp by
13.1%. The increase in sales volume mainly results from the increase in production capacity of pulp at the Nueva Aldea Mill from 856,000 to 1,027,000 tons per year as of March 2009.

Wood Products Sales

Sales of wood products, including sawn timber and remanufactured products decreased by 31.3%, from U.S.$718.3 million in 2008 to
U.S.$493.8 million in 2009, reflecting a 22.3% decrease in sales volume and a 11.5% decrease in average prices. Sawn timber sales revenue decreased 36.0%, from U.S.$471.6 million in 2008 to U.S.$301.9 million in 2009, due principally to a 22.6%
decrease in the sales volume of wood products and a decrease of 17.3% in average prices. Sales of remanufactured wood products decreased 22.2% from U.S.$246.6 million in 2008 to U.S.$191.9 million in 2009, due to a 2.9% decrease in average prices
and a 19.9% decrease in sales volume. The decrease in the sales volume of wood products sales was mainly attributable to the closure of four of our sawmills during 2008. These closures were directly related to the weakening of the construction
sector in the United States and Latin America in 2008 as a result of the global financial crisis.

Plywood and Fiberboard
Panels Sales

Sales of plywood and fiberboard panels decreased 12.2%, from U.S.$946.9 million in 2008 to U.S.$831.0 million
in 2009. This decrease was primarily due to an average price decrease of 21.1%, which was partially offset by an 11.2% increase in sales volume. The decrease in prices, which has affected the majority of our panel product lines, resulted from the
weakening of the construction sector in 2009, particularly in Latin America and the United States, and an oversupply of panels in the Brazilian market, which added downward pressure to the prices of panels during the second half of 2009. The
increase in sales volume is largely attributable to our acquisition of Tafisa in August 2009, which added 640,000 cubic meters of annual capacity to our panels business. See Item 4. Description of BusinessHistory.

Forestry Sales

Sales revenue from forestry products decreased by 19.6%, from U.S.$101.6 million in 2008 to U.S.$81.7 million in 2009. This decrease is
mainly due to a decrease in sales volume of 31.0% of sawlogs, pulplogs and chips, which was partially offset by a 16.6% increase in the average prices of forestry products as compared to 2008.

Cost of Sales

Cost of sales decreased by 7.7% from U.S.$2,331.9 million for 2008 to U.S.$2,152.5 million for 2009, primarily due to an overall decrease
in the per unit cost of production for most of our products. In particular, we saw an annual decrease in our timber, forestry labor and chemicals costs of 14.0%, 14.3% and 22.9% respectively. These decreases were partially offset by both an increase
in our maintenance costs and depreciation.

Gross Margins

Gross margins decreased from 37.2% for 2008 to 30.9% for 2009, primarily due to decreases in average sales prices, which was partially
offset by a decrease in the per unit cost of sales.

Other Operating Income

Other operating income increased 75.8% from U.S.$104.3 million in 2008 to U.S.$183.3 million in 2009, primarily as a result of an increase
in the fair value of our biological assets. This increase in fair value is mainly explained by the higher price of wood, an increase in volume of our forests and an older average age of the trees in 2009 compared to 2008.

Distribution Costs

The distribution costs for all markets decreased from U.S.$455.2 million in 2008 to U.S.$388.5 million in 2009, mainly due to a decrease
in the per unit freight cost of our exports. This decrease in our freight costs was a result of the global financial crisis and the oversupply of shipment capacity.

Administrative Expenses

In 2009, administrative expenses were similar to those of 2008, slightly decreasing from U.S.$247.0 million to U.S.$242.2 million.

Financial Costs

Financial costs increased 10.6% from U.S.$175.2 million in 2008 to U.S.193.9 million in 2009, primarily due to an increase in interest
expense of 13.5%, partially offset by a decrease in other financial costs of 1.9% as compared to 2008. Our interest expense increased as result of higher levels of long-term debt; in particular, this increase was the result of U.S.$142.0 million in
long-term debt we issued in March 2009 in the local market and U.S.$500 million we issued in July 2009 in the U.S. market.

Exchange Rate Differences

We recorded foreign exchange gains of U.S.$17.6 million in 2009 compared to losses of U.S.$67.8 million in 2008. During 2009, the Chilean
peso appreciated 20.3% against the U.S. dollar compared to 2008, which positively impacted our sales and other accounts receivables positions recorded in Chilean Pesos. In the same period the Brazilian Real depreciated 34.2% against the U.S. dollar
in 2009, which also positively impacted our related party payables position recorded in Brazilian Reals.

Negative Goodwill
Immediately Recognized

Negative goodwill immediately recognized increased to U.S.$36.9 million in 2009 from zero in 2008.
This increase is a result of our purchase of ENCEs main assets in Uruguay at a purchase price below market value, which allowed us to recognize negative goodwill. SeeItem 4. Description of BusinessHistory.

Other Profit (Loss)

In 2009, we earned other profit of U.S.$27.2 million, as compared to the other losses we incurred in 2008 of U.S.$0.4 million. This
increase was primarily due to the gain that we recorded as a result of our contribution of 50% of our equity in Forestal Conosur S.A. (our wholly-owned subsidiary in Uruguay) to our joint venture with Stora Enso, Montes del Plata. This contribution
resulted in a change in control of Forestal Conosur S.A., which allowed us to recognize the assets and liabilities contributed to the joint venture at fair value under the equity method rather than at book value on a consolidated basis which
resulted in a gain for Arauco. SeeItem 4. Description of BusinessHistory.

Income Tax

In 2009, we incurred income tax expenses of U.S.$53.5 million, which is a decrease of U.S.$44.5 million from the income
tax expenses of U.S.$98.0 million in 2008. This decrease was principally due to our lower profit before income tax and to the increase in non-taxable items.

Net Profit

Net profit decreased 33.0% from U.S.$405.0 million in 2008 to U.S.$304.6 million in 2009. The main cause of this decrease was the global
financial crisis that continued to negatively affect the construction sector throughout 2009, which resulted in decreases in both our prices and total sales revenues.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity are funds from operations, domestic and international borrowings from commercial and investment banks
and debt offerings in the domestic and international capital markets.

Our net cash flow provided by operating activities was
U.S.$751.0 million during the year ended December 31, 2009 and U.S.$769.7 million during the year ended December 31, 2008. The decrease in net cash provided from operating activities in 2009 as compared to 2008 was principally due to a
lower collection of accounts receivable as a result of decreasing sales of our products. The decrease in income is explained by the global financial crisis.

Our net cash used in investing activities increased from U.S.$466.7 million during the year ended December 31, 2008 to U.S.$717.3
million during the same period of 2009. This increase is primarily explained by the acquisition of Tafisa Brasil for U.S.$167.0 million in August 2009 and the acquisition of forest assets through a joint venture with Stora Enso for U.S.$167.5
million in October 2009.

Our net cash related to financing activities increased from U.S.$378.5 million used in financing
activities during the year ended December 31, 2008 to U.S.$302.4 million provided by financing activities during the year ended December 31, 2009. This increase is mainly due to an increase in our levels of debt. In March 2009, we issued
two bond series for approximately U.S.$142.0 million in the local market and in July 2009 we issued U.S.$500 million in the U.S. market.

In accordance with customary practice in the pulp industry, we do not have long-term sales contracts with our customers (except for in a
few limited cases); rather, we maintain relationships with our customers pursuant to which we reach agreements from time to time on specific volumes and prices.

We expect our principal capital expenditures for 2010 to include the acquisition of biological assets, the biomass cogeneration power
plant at the Viñales sawmill, an increase in the production capacity of the Nueva Aldea Mill and the repair of property and assets damaged by the earthquake of February 27, 2010. SeeItem 4. Information on the
CompanyCapital Expenditures. For subsequent years, our capital expenditures will depend on the state of the economy in each country where we have operations, as well as market conditions.

We believe that cash flow generated by operations, cash balances, borrowings from commercial banks and debt offerings in the domestic and
international capital markets will be sufficient to meet our working capital, debt service and capital expenditure requirements for the foreseeable future.

The following table sets forth certain contractual obligations as of December 31, 2009, and the period in which the contractual
obligations come due.

Our total long-term bank, export credit agency and multilateral lending agency debt
(including the current portion of such debt) was U.S.$389.0 million at December 31, 2009, of which 97.6% was U.S. dollar-denominated. At December 31, 2009, we also had total capital markets borrowings (including the current portion of such
debt) of U.S.$2,686.6 million, 84.5% of which was U.S. dollar-denominated. At December 31, 2009, the weighted average maturity of our long-term debt was seven years. The interest rate on our variable rate debt is determined principally by
reference to the London inter-bank offered rate (LIBOR), and at December 31, 2009 the average interest rate for our U.S. dollar floating rate debt over six-month LIBOR was 0.2%. The average interest rate for our U.S. dollar fixed rate debt was
6.9%. These average rates do not reflect the effect of swap agreements and subsequent unwinds effective as of December 31, 2009.

The following are our principal financing activities during 2009 and through the date of this annual report:

On March 18, 2009, Arauco issued two series of bonds for approximately U.S.$142 million in the Chilean local market. The first series
of bonds in an aggregate principal amount of 2,000,000 UF was issued at 4.54% with a maturity of 21 years and a grace period of 10 years. The second series of bonds in an aggregate principal amount of 2,000,000 UF was issued at 3.35% with a maturity
of 5 years and a grace period of 2 years. Both series of bonds received a local rating of AA by Fitch Ratings and Feller-Rate.

On July 27, 2009, Arauco issued bonds (the 144A Bonds) in accordance with Rule 144A and Regulation S under the
Securities Act of 1933 for a total amount of U.S.$500,000,000 at 7.25% with a maturity of 10 years. Pursuant to the terms of the 144A Bonds, the bondholders had the option to exchange the 144A Bonds for bonds registered with the Securities and
Exchange Commission. As a result, beginning on October 15, 2009 and ending on November 13, 2009, the Company carried out an exchange offer whereby approximately 99.8% of the 144A Bonds were exchanged for new registered bonds.

The instruments and agreements governing our bank loans and local bonds set limits on our incurrence of debt and liabilities through the
use of financial covenants. The principal financial covenants contained in the bank loan agreements are as follows:



| |  |  | Our debt to equity ratio must not exceed 1.2:1;
| | - |  | -----------------------------------------------



| |  |  | Our interest coverage ratio must not be less than 2:1; and
| | - |  | ----------------------------------------------------------



| |  |  | We are required to maintain a minimum consolidated net worth of U.S.$2.5 billion, as measured in accordance with IFRS.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

The principal financial covenant contained in the local bond agreements is:



| |  |  | Our debt to equity ratio must not exceed 1.2:1.
| | - |  | -----------------------------------------------

We were in compliance with these covenants for both bank loans and local bonds agreements as of December 31, 2009.

Substantially all of our borrowings are denominated in dollars. See Item 11. Quantitative and Qualitative Disclosures about
Market RiskForeign Currency Risk.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any off-balance sheet arrangements.

TREASURY MANAGEMENT

Our treasury activities are centrally governed by our cash and deposits policy, which sets corporate guidelines for all of our
subsidiaries with respect to treasury management. Our international subsidiaries are aligned with these general corporate guidelines and may adopt specific policies to meet local needs. Our cash and deposits policy was developed by our Chief
Financial Officer (CFO) and it is periodically revised.

Our corporate finance office is based in Santiago, Chile and manages
our treasury activities in Chile. The corporate finance office also oversees our treasury activities outside of Chile, which are managed by our financial directors for each country in which we operate. Our CFO reviews, normally on a daily basis, our
cash balance on a consolidated basis and anticipates short- and long-term cash needs according to the companys normal operations, capital expenditures and obligations.

Our Chilean subsidiaries borrow from or lend money to us in accordance with their daily cash requirements or surplus, maintaining their
cash balance close to zero. Our policy is to invest all cash we receive from our Chilean subsidiaries in financial instruments on a centralized basis.

HEDGING

We periodically review our exposure to risks arising from fluctuations in foreign exchange rates and interest rates and make a
determination, on a case-by-case basis, at our senior management level whether or not to hedge such risks. As a result, from time to time we enter into currency and interest rate swaps with respect to a portion of our borrowings. See Note 23
to our audited consolidated financial statements.

We have two offsetting interest rate swap agreements outstanding, each in a
notional amount of U.S.$130 million, with respect to the interest rate on our 7.75% Notes due 2011. These interest rate swaps settle semi-annually and terminate in 2011. The net effect of our interest rate swap agreements is that we pay fixed
interest at a rate of 5.506% and receive fixed interest at a rate of 7.75%. See Note 23 to our audited consolidated financial statements.

The Bío Bío Investment Fund entered into one interest rate swap agreement, in an initial notional amount of U.S.$240
million with amortizations during the life of the swap in the same amount and dates of the amortizations of the credit agreement the Bío Bío Investment Fund obtained on October 6, 2006, with interest rate settled quarterly and
with a final maturity in October 2013. The net effect of this interest rate swap agreement is that the Bío Bío Investment Fund pays fixed interest rate at a rate of 5.256% and receives a floating rate at 3 months LIBOR. In January
2007, the Bío Bío Investment Fund transferred all of its assets and financial debt to Forestal Río Grande S.A.

Arauco entered into the following two cross currency swap agreements to hedge the amount of the UF 2,000,000 local bond issued in March
2009:



| |  |  | A cross currency swap agreement with Banco de Chile for UF 1,000,000. Arauco receives semi-annual interest based on the notional amount of UF 1,000,000
at a rate of 2.25% and pays semi-annual interest based on the notional amount of U.S.$35,700,986.39, which is equivalent to UF 1,000,000 at the currency exchange rate at the date of the agreement, at a rate of 4.99%. This swap matures in March 2014.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A cross currency swap agreement with JPMorgan Chase Bank for UF 1,000,000. Arauco receives semi-annual interest based on the notional amount of UF
1,000,000 at a rate of 2.25% and it pays semi-annual interest based on the notional amount of U.S.$35,281,193.28, which is the equivalent to UF 1,000,000 at the currency exchange rate at the date of the agreement, at a rate of 4.94%. This swap
agreement matures in March 2014.

1,000,000 at a rate of 4.25% and it pays semi-annual interest based on the notional amount of U.S.$38.42 million, which is equivalent to UF 1,000,000 at the currency exchange rate at the date of the agreement of 5.62%. This swap agreement matures in

These cross currency swap agreements allow us to address uncertainties regarding exchange
rates. Through these agreements, we receive cash flows in UF, which allow us to comply with the terms of the bonds and pay fixed amounts in dollars, the currency in which a significant amount of our assets are denominated.

We have also analyzed our exposure to risks associated with fluctuations in prices of commodities, including pulp, but have, thus far,
not entered into any material hedging transactions with respect to such risks. See Item 11. Quantitative and Qualitative Disclosures About Market Risk.

RESEARCH AND DEVELOPMENT

We spent U.S.$3.2 million in 2007, U.S.$3.8 million in 2008 and U.S.$3.9 million in 2009 on research and development. We conduct our
principal research and development programs through Bioforest, which concentrates its efforts on applying and implementing the advanced technology available in the market to the specific characteristics of our forests and mills.

We are continuously researching and attempting to develop different strains of long-fiber pine trees to improve their quality and to
shorten the average harvest cycle. Additionally, we maintain close relations with international research institutes, equipment suppliers and the scientific and engineering community involved with our industry.

TREND INFORMATION

On February 27, 2010, a severe earthquake, followed by a tsunami, occurred off the coast of the southern-central region of Chile,
which is an area where we maintain our industrial operations. Immediately after the earthquake, all of our production units applied their contingency plans, which involved shutting down operations and evaluating the damage caused to each facility by
the earthquake. As a result of the earthquake and subsequent

tsunami, our Mutrún sawmill was completely destroyed. Our other operations that were affected by the earthquake and tsunami have been reopening gradually, with the timing of such
reopenings depending on the specific conditions of the respective mill as well as external factors such as infrastructure conditions, road connectivity, power supply and public safety concerns. As of June 22, 2010, all of our operations were
operating except for line two of the Arauco Pulp Mill (Arauco II), which will be reopened once the damages are assessed and repaired.

The suspension of our operations in Chile resulted in a decrease in sales volumes and adverse effects on our results of operations,
subject to any recoveries under our insurance policies. Our insurance policies cover damages to our property, plant, equipment and inventories and business interruption up to an amount of U.S.$650 million, with a deductible for such damages of
U.S.$3.3 million and a deductible of 21 days for business interruption. For the first quarter of 2010, we recorded a loss for damages to our property, plant and equipment and inventories of approximately U.S.$27 million, net of insurance coverage.
As the date of this annual report, we expect to incur additional losses as a result of the earthquake and subsequent tsunami, but we cannot determine the total amount of such losses at this time.

Pulp sales reached U.S. $386.3 million during the first quarter of 2010, a 6.6% increase compared to the same quarter of the previous
year. This increase is mainly explained by higher average prices of 49.2%, partially offset by lower sales volume of 25.9%. The lower sales volume is largely explained by the interruption of operations at our pulp mills in March 2010 as a result of
the earthquake that hit the central and southern regions of Chile on February 27, 2010.

The global financial crisis that
affected the world paper market, especially in Europe and North America, led to a substantial decrease in the prices of our products during the last quarter of 2008. Prices began to show a slight recovery during the second quarter of 2009, and then
continued increasing for the rest of the year, almost reaching pre-crisis levels in the last quarter of 2009. The recovery in the pulp market was confirmed during the fourth quarter of 2009 and the first quarter of 2010, during which time pulp
prices have grown strongly, reaching near pre-crisis levels. We expect this positive price trend to continue throughout the remainder of 2010, although at a slower pace than that of the fourth quarter of 2009 and the first quarter of 2010.

Although inventory levels increased slightly at the end of the fourth quarter of 2009, on average inventory levels were low
as compared to 2008 levels. World stock levels at March 2010 were 23 days for long fiber and 29 days for short fiber, showing little variation from the same levels as December 2009, which were 23 and 30 days, respectively.

The European paper market is still facing challenging circumstances. Local producers have not been able to transfer the higher global
pulp prices to paper products, consequently suffering decreases in margin due to the higher costs of raw material. Also, the sovereign debt crisis in Greece that occurred in the first months of 2010 has impacted the value of the euro against the US
dollar, which increased European pulp-buyer prices in euro terms. The status of the overall European economy is uncertain in the short term, and the pulp market may be negatively impacted if the crisis spreads to other European countries, as there
is a close relationship between the health of the economy of a region and its pulp and paper demand.

During the first months
of 2010, Asian countries (mainly China, Korea and India) continued to have increased demand for pulp, leading to pulp price increases throughout the region. Local producers are finding it difficult to transfer these price increases to their own
products, but they are still in a relatively comfortable position due to past purchases. Paper production is still very strong for local consumption and exports, fostering initiatives in Europe and North America for the establishment of tariffs on
most competitive products from these Asian countries. During the last quarter of 2009, the market in general was very strong in Asia, particularly China, a trend we should continue to see in the mid-term as new paper production will continue to come
from Asia and paper will be exported from these markets to Europe and North America.

For North American producers, the last
quarter of 2009 brought several challenges that may continue to be material during 2010. First, despite the strong lobby of American kraft pulp producers, the United States Senate decided not to renew the black liquor subsidy as a renewable
alternative fuel. Second, North American paper producers are facing strong competition coming from China, Indonesia and Korea, and are claiming antidumping measures against Chinese and Indonesian producers. In North America, during the first quarter
of 2010, we have

observed a lower demand for pulp and a lower production of paper mainly due to mill closures. This volume has been replaced by imports coming from China, South Korea and Indonesia.

Our sawn timber and panels business is strongly related to the real estate and construction industries. The real estate and construction
markets in the United States have showed signs of improvement during 2010, however, construction levels are still at their lowest in 50 years. During the early months of 2010, homebuilding levels have improved and have been on track to reach 600,000
units per year, as compared to an average of 580,000 units during 2009, and we expect the trend will remain positive throughout 2010. In Chile the construction sector has shown strong activity after the earthquake and we expect this will positively
impact the demand for our panels, molding and wood products.

DIRECTORS AND EXECUTIVE OFFICERS

Directors

A board of
directors manages our business. Our by-laws (estatutos) require that the board of directors consist of nine directors. Our directors cannot also be our executives. The entire board is elected every three years and can be re-elected for any
number of periods. The current board was elected in April 2010, and their terms will expire in 2013. The board may appoint replacements to fill any vacancies that occur during periods between elections; however, at the annual shareholders
meeting following any such replacement, an election of the entire board must take place. Scheduled meetings of the board of directors are, generally, held once a month. Extraordinary board meetings are called when summoned by the Chairman or when
requested by at least two directors.

We do not have an audit committee or compensation committee.

Our current directors are listed below.

In addition, as of December 31, 2009, we had
contracts with approximately 992 contractors, who employed approximately 26,899 employees. Contractors that are not affiliated with us or with each other operate our eight sawmills and six remanufacturing facilities in Chile. The 12 independent
contractors that operate our Chilean sawmills had 2,757employees at December 31, 2009. The independent contractors that operate our Chilean remanufacturing facilities had 1,887 employees at December 31, 2009 and the independent contractor
that operates the laminating beams line employed 60 employees at December 31, 2009.

Under Chilean labor legislation, we
are secondarily liable for the payment of labor and the social security obligations owed to employees of our contractors. In the event that we do not exercise the rights granted to us by the labor laws regarding the supervision of our contractors in
their compliance of their labor and social security obligations, then our responsibility is elevated from secondary to joint and several, thus enabling an employee of a contractor to bring a claim relating to these obligations against both the
contractor and to us, as the party hiring such contractor, although the contractor would remain primarily liable for such obligations. Furthermore, we are also responsible for the health and safety conditions of the contractors workers and are
obligated to ensure that the contractors comply with all obligations related to such conditions while such workers are performing activities for us within our corporate purpose.

Approximately 21.0% of our employees in Chile, 51.2% of our employees in Argentina and 19.8% of our employees in Brazil were unionized at
December 31, 2009. We negotiate collective bargaining agreements of two or three years duration with unionized employees.

We have stable employee relations in Chile, Argentina and Brazil. Our Chilean operations have not experienced any work stoppages in the
last five years other than (i) a ten-day work stoppage in November 2009 at our Constitución, Arauco, Nueva Aldea, Horcones and Cholguán complexes (ii) a three-day work stoppage in September 2009 at our Constitución,
Arauco, Nueva Aldea, Horcones, Valdivia and Trupán-Cholguán complexes; and (iii) a six-day work stoppage in May 2007 at our Horcones complex (which includes the Arauco pulp mill, a panel plant and two sawmills), each of which was
caused by the employees of our third party forestry contractors at each of the respective facilities.

In Argentina, during
January 2008, the chemical mill in Argentina experienced three days of work stoppage, but these strikes were limited to two hours per shift and did not materially affect operations. In addition, in January and February 2007, we experienced
(i) a 12-day stoppage at the Faplac mill due to problems with the labor union of its chemical division and (ii) a six-day suspension of operations at our Alto Paraná mill as a result of a strike by a group of approximately 150 power
saw operators.

During the last five years, there have been no strikes or other material work stoppages at our Brazilian
subsidiaries.

RELATED PARTY TRANSACTIONS

We engage in a variety of transactions in the ordinary course of business with related parties. Related parties include, among others,
directors, officers and affiliates of the Company. The new Title XVI, or Title XVI, of the Chilean Companies Act, which was included by Law No 20,382 published in the Official Gazette on October 20, 2009, amended among others,
articles 44 and 89 of the Chilean Companies Act, establishing the applicable norms for transactions with related parties by and among public corporations and their subsidiaries. Title XVI requires that our transactions with related parties
contribute to the companys interest and be on a market basis or on terms similar to those prevailing in the market. In addition, Title XVI provides that related party transactions must be approved by an informed majority of the disinterested
members of the board of directors. If a majority of the disinterested directors abstains from voting on a particular transaction, the transaction must be approved by a unanimous vote of the non-abstaining disinterested directors or by two-thirds of
the shares with voting rights. Resolutions approving any such transactions must be reported to our shareholders at the next annual shareholders meeting.

Notwithstanding the above, in accordance with Article 147 of the Chilean Companies Act, our Board has resolved that the following
transactions with related parties do not need to follow the procedure set forth in the previous paragraph: (i) transactions which do not involve material amounts; (ii) transactions with affiliates in which we control 95% or more of the
equity; and (iii) transactions that are considered by our Board to be performed in the ordinary course of our business in accordance with our general policy of customary dealings, which was approved by our Board on December 29, 2009 and is
available to shareholders at our main office and is published on our website, at www.arauco.cl.

(obligaciones negociables) issued by Alto Paraná S.A. in 2001 (the APSA Notes) and other existing debt and to finance capital expenditures in the ordinary course of business, Alto Paraná S.A. issued U.S.$270 million
of 6.375% Notes due 2017 in the form of Rule 144A/Regulation S notes sold in the local and international capital markets. Arauco fully and unconditionally guaranteed these notes. Alto Paraná paid down the APSA Notes with the proceeds of the
6.375% Notes.

EXPORT SALES

Export sales constituted approximately 76.2% of our sales revenue for the year ended December 31, 2009. Our total export sales
revenue for 2009 was U.S.$3.1 million. Our principal overseas markets are Asia, North America and Western Europe. SeeItem 4. Information on the CompanyDescription of BusinessDomestic and Export Sales.

LEGAL PROCEEDINGS

We have been and continue to be subject to environmental proceedings related to allegations by the Chilean environmental regulators and
private parties. We are also subject to certain other legal proceedings arising from the ordinary course of our business. For more information regarding the environmental proceedings and other legal proceedings arising from the ordinary course of
business, see Note 19 to our audited consolidated financial statements.

Since the end of 2004, various criminal proceedings
relating to alleged violations of several environmental laws have been instituted in Chile in which some of our mills may be affected. We cannot predict the outcome or impact of these proceedings or when they may be resolved. While Chilean law in
general provides that only individuals can be convicted in criminal actions, as a consequence of these proceedings, certain measures may be taken that could materially and adversely affect our business, financial conditions , results of operations
and cash flows. As an exception of the abovementioned general rule, Chilean Law No 20,393, which was published in the Official Gazette on December 2, 2009, established the criminal responsibility of legal entities for criminal offenses
related to the financing of terrorism, money laundering or bribery. We do not have knowledge of any fact that could

result in such criminal responsibility for the Company. See Item 8. Financial InformationLegal Proceedings. SeeItem 3. Key InformationRisk FactorsRisks
Relating to Arauco and the Forestry IndustryWe are subject to legal proceedings related to our mills, which could adversely affect our business, financial condition, results of operations and cash flows.

Valdivia Mill

Our
operations at the Valdivia Mill have been subject to continued environmental scrutiny by Chilean environmental regulators and the Chilean public since the mill began its operations in 2004. A variety of concerns and claims have been raised regarding
potential environmental impacts in the area.

The COREMA for the Tenth Region of Chile evaluated claims regarding the
migration and death of black-neck swans, whose habitat in the nearby Carlos Anwandter Nature Sanctuary is downstream from the mill on the Cruces River. There have been allegations of a causal connection between the migration and death of black-neck
swans and the operations at the Valdivia mill, and in a study dated April 18, 2005, researchers at the Austral University in Valdivia concluded that wastewater discharges from the Valdivia Mill had significantly altered the quality of the
Cruces River. The study also concluded that the effluent discharges were a significant contributing factor in the death or migration of a large population of the black-necked swans in the Carlos Anwandter Nature Sanctuary downstream from the
Valdivia Mill. The National Defense Council instituted an action seeking reparations, damages and indemnification from us for environmental harm allegedly caused by the discharges from the Valdivia Mill. In response, we have argued to the court that
this action should be rejected, as several studies have demonstrated that there is no relationship between the alleged damages and the operation of the Valdivia Mill.

On June 8, 2005, we voluntarily suspended operations at the Valdivia Mill pending the receipt of legal and technical guidance
from the applicable regulatory authorities. We estimate this voluntary suspension resulted in a loss of sales of approximately U.S.$1.0 million per day and a loss of profits of approximately U.S.$250,000 per day. Pursuant to the decision of our
board of directors, based on certain clarifications provided by the Environmental Regional Commission (Comisión Regional del Medio Ambiente), or COREMA, of the Tenth Region of Chile, the mill resumed operations on
August 12, 2005 at 80% of its authorized production capacity after 64 days of suspended operations. In order to achieve the full production capacity authorized by applicable permits, the mill had to fulfill certain new requirements established
by the COREMA. On January 18, 2008, the COREMA authorized the Valdivia Mill to return to its annual authorized production capacity of 550,000 metric tons. The mill gradually increased its production over a four-month period starting in March
2008 and reached full capacity in June 2008. The suspension of operations at the Valdivia Mill adversely affected our business, financial condition, results of operations and cash flows. Any future suspension of operations at the Valdivia Mill or at
any other of our significant operating plants can be expected to have similar adverse effects. We offer no assurance that the Valdivia Mill will be able to operate without further interruption. SeeItem 3. Key
InformationRisk FactorsRisks Relating to Arauco and the Forestry IndustryEnvironmental concerns led us to temporarily suspend our operations at the Valdivia Mill, which adversely affected, and in the future may continue to
adversely affect, our business, financial condition, results of operations and cash flows and Item 4. Information on the CompanyDescription of BusinessPulpPulp millsChileValdivia Mill.

In June 2007, we submitted to the COREMA of the Tenth Region of Chile an environmental impact study for the
implementation of substantial technological improvements on the quality of the effluents generated by the Valdivia Mill. On June 30, 2008, the COREMA approved that environmental impact study. However, the approval was subject to certain
conditions that, in the opinion of Arauco, affected the feasibility of the project. For such reason, Arauco filed an appeal (recurso de reclamación) before the Directive Council (Consejo Directivo) of the Environmental National
Commission (Comisión Nacional del Medio Ambiente), or CONAMA, challenging the conditions. Such appeal (recurso de reclamación) was partially accepted by the CONAMA. However, some conditions that affect the feasibility of
the project were maintained. As a consequence, on September 17, 2009, we presented another appeal (recurso de reclamación) before the ordinary courts of justice, which appeal has not been resolved as of the date of this annual
report.

On February 19, 2009, we submitted to the COREMA of the Fourteenth Region of Chile an environmental impact study
for the construction of a pipeline to discharge the Valdivia Mills wastewater in the Pacific Ocean near Punta Maiquillahue, that is, in a body of water other than the Cruces River, the Carlos Anwandter Nature Sanctuary



65

##### Table of Contents

or their sources. The pipeline would transport the wastewaters of the Valdivia mill through an extension of 37 kilometers from the Valdivia mill to Punta Maiquillahue and would finally discharge
the wastewater two kilometers inside the Pacific Ocean. Such environmental impact study was approved with certain conditions by the COREMA by resolution dated February 24, 2010. We have challenged these conditions before the Directive Council
(Consejo Directivo) of the CONAMA. As of the date of this annual report, the Directive Council of the CONAMA has not resolved the action presented by us. As stated in the environmental impact study, the construction of this pipeline will
commence once (i) the COREMA approves the environmental impact study in its final form, and (ii) all necessary permits for the construction of the pipeline have been issued by the competent authorities. In the environmental impact study,
we estimated that the construction of the pipeline will take 24 months. Once the construction of the pipeline has been completed, we will conduct a 6-month trial phase of the pipeline and will then begin normal operations.

Approvals by the COREMA and the judicial courts, as well as the construction and operation of the pipeline are each subject to many
environmental, regulatory, engineering and political uncertainties. As a result, we cannot provide any assurances that the projects will be finally approved as requested or completed. If our request for the necessary permits for the construction of
the pipeline is rejected, or if the installation of the pipeline is delayed for reasons attributable to us, we may face sanctions that include warnings, fines or the revocation of the Valdivia Mills environmental permit for operation.
Alternatively, if any rejections or delays are attributable to reasons beyond our control (such as a force majeure or the acts of a third party), we believe that the Chilean environmental authorities should extend the applicable deadlines for the
completion of these projects. However, we can provide no assurances that any deadline extensions would be granted, even if we comply with all the requirements that may be set forth by those authorities. SeeItem 3. Key
InformationRisk FactorsRisks Relating to Arauco and the Forestry IndustryEnvironmental concerns led us to temporarily suspend our operations at the Valdivia Mill, which adversely affected, and in the future may continue to
adversely affect, our business, financial condition, results of operations and cash flows and Item 4. Information on the CompanyDescription of BusinessPulpPulp millsChileValdivia Mill.

As part of the environmental resolution that modified the Valdivia Mill environmental permit in 2005, the COREMA of the Tenth Region
asked CONAF to elaborate an Integral Environmental Management Plan for the wetland, which was completed in 2006. The plan concluded that there was a need to develop a Conceptual Ecosystem Model for the wetland. CONAF selected the Science Faculty of
the University of Chile to conduct this study.

The study indicated in its second progress report that the disappearance of
the luchecillo, a water weed that was an important food source of black-necked swans, was likely related to natural causes. Specifically, the study proposed that the disappearance of the luchecillo was caused by the
convergence of three factors in May 2004: (i) low levels of precipitation, (ii) low levels of water flow in the rivers and the wetland and (iii) three instances in which temperatures reached zero degrees Celsius or lower. According to
the study, the simultaneous occurrence of these factors was likely responsible for the disappearance of the luchecillo which, in turn, lead to the death and migration of the swans. This second progress report was followed by a final
report issued by the Science Faculty of the University of Chile, which was not approved by CONAF.

Nueva Aldea

In January 2001, we obtained environmental approval for the Nueva Aldea Project that included the construction of a pulp mill with an
annual production capacity of 550,000 metric tons. After obtaining approval, we determined that we could increase the annual production capacity of the mill to 856,000 tons without an additional environmental impact study. The COREMA for the Eighth
Region of Chile determined that it was necessary to formally review the difference in capacity before we proceeded with construction, and in August 2004, we submitted a new environmental impact study that considered the higher capacity. In September
2004, while this new study was under consideration, we began construction of the pulp mill according to the parameters approved in 2001. The COREMA for the Eighth Region of Chile disagreed with our decision and, on January 12, 2005, initiated
an administrative proceeding and ordered suspension of construction of the mill until the new environmental impact study was approved.

##### Table of Contents

On March 10, 2005, the COREMA for the Eighth Region of Chile unanimously approved the
new study and expressly authorized construction of the mill with installed annual capacity of 856,000 metric tons. We promptly resumed the construction of the pulp mill. The COREMA for the Eighth Region of Chiles new approval requires
submission of a new environmental impact study of the discharge of wastewater through a pipeline into the sea. On February 20, 2006, the COREMA of the Eighth Region of Chile approved this new environmental impact study. Proceedings relating to
these approvals were decided on October 17, 2008 by the CONAMA without affecting the rights of Arauco. See Note 12 to our audited consolidated financial statements.

Licancel Mill

Beginning
in June 2007, our operations at the Licancel Mill, a pulp mill located in the Seventh Region of Chile, became subject to environmental scrutiny by Chilean environmental regulators and the public. On June 5, 2007, in connection with the death of
fish in the Mataquito River, approximately 15 kilometers downstream of the mill, we decided to voluntarily suspend our operations in the Licancel Mill as a preventive measure. In addition, Chilean authorities, including the health authorities and
the Superintendencia de Servicios Sanitarios(Sanitary Services Superintendency), required that we suspend activities at the Licancel Mill and that we suspend any further discharges into the river. On June 18, 2007, as a result of a pipe
leakage in the effluent treatment system currently in place at the Licancel Mill, an estimated 50 cubic meters of effluents reached the Mataquito River. On that same date, we decided to close the mill indefinitely and informed the Sanitary Services
Superintendency of the incident. On October 3, 2007, we requested to the health authority (Autoridad Sanitaria) of the Seventh Region of Chile that it remove the suspension of activities at the Licancel Mill. On October 22, 2007,
the health authority of the Seventh Region of Chile removed the suspension and imposed certain conditions relating to our activities in the mill consisting primarily of the implementation of certain emergency detection and control programs and
systems, with which we have complied. Furthermore, on November 12, 2007 the Sanitary Services Superintendency removed the suspension regarding the release of discharges by the Licancel Mill. The mill resumed operations during January 2008,
using the new effluent treatment system in which we invested U.S. $8 million during 2007.

On September 7, 2007, the
National Defense Council instituted a civil lawsuit seeking reparations, damages and indemnification from us for environmental harm allegedly caused by the Licancel Mill. The National Defense Council agreed to terminate this lawsuit pursuant to an
agreement with Arauco dated January 29, 2010. However, the resolution that approved the agreement and declared the lawsuit terminated was challenged by certain third parties. This action remains under review by the tribunal as of the date of
this annual report. Several other administrative and judicial proceedings have been commenced as a result of the event at the Licancel Mill, including one proceeding arising from the death of fish at the Mataquito River.

Tax Litigation in Argentina

On December 14, 2007, Argentinas internal revenue service (AFIP), notified our Argentine subsidiary, Alto Paraná S.A.,
of a claim for unpaid taxes in the amount of approximately AR $418 million (including principal, interest and penalties), arising from a dispute regarding certain income tax deductions taken by Alto Paraná S.A. in connection with certain debt
service payments made beginning in 2001 in respect of outstanding bonds. On February 8, 2010, Argentinas Tribunal Fiscal de la Nación issued an unfavorable administrative ruling requiring that Alto Paraná S.A. satisfy the
abovementioned claim.

Alto Paranás legal and tax advisors continue to believe that this claim lacks merit, and
as a result, Alto Paraná has appealed the decision to the Court of Appeals. Alto Paraná also filed an injunctive action requesting that the court stay the companys payment obligation until the appeal has been fully resolved. On
May 13, 2010, the Court of Appeals granted the request in exchange for a guarantee by Alto Paraná until the final judgment has been issued.

Tax Litigation in Chile

On August 25, 2005, the Chilean Servicio de Impuestos Internos (the Chilean IRS) issued tax calculations
No. 184 and No. 185 of 2005 objecting to certain capital reduction transactions effected by Arauco on April 16, 2001 and October 31, 2001, and furthermore, requested reimbursement from the Company for amounts

##### Table of Contents

returned to it in respect of certain claimed tax losses. On November 7, 2005, the Company requested a Review of the Supervision Action (Revisión de la Actuación
Fiscalizadora, or RAF), which is an administrative review of the tax action brought by the Chilean IRS, and subsidiarily, a claim was filed against the abovementioned tax calculations No. 184 and 185 of 2005. The RAF was
resolved on January 9, 2009 by the Chilean IRS, which resolution, however, only partially sustained the Companys request. In response, the Company filed an additional complaint with regard to the portion of the RAF that was not granted by
the administrative review. As of the date of this annual report, the investigation in respect of this complaint is pending.

The Company believes that its position in respect of this complaint is supported by solid legal arguments and that there is a reasonable
likelihood that this matter will result in a favorable outcome for the Company. However, if this result does not occur, it is possible that an obligation will arise for the amount specified, which was $3,362,265,453 Chilean Pesos, plus any accrued
interest as of the payment date.

DIVIDEND POLICY

Chilean law currently requires that, unless otherwise decided by the unanimous vote of our issued and subscribed shares eligible to vote,
public corporations distribute a cash dividend in an amount equal to at least 30% of the corporations consolidated net income for each year on the basis of IFRS, unless and except to the extent the corporation has unabsorbed losses from prior
years. In April 2002, our shareholders approved the current dividend policy, setting the cash dividend at 40% of our consolidated net income for each year which was determined on a Chilean GAAP basis through the year ended December 31, 2008,
and as of January 1, 2009, is now determined on an IFRS basis. In accordance with IFRS, the determination of the dividend amount is based on the effective realized profit net of any relevant variations in the value of unrealized assets and
liabilities. For information regarding the differences between Chilean GAAP and IFRS, see note 2 to our audited consolidated financial statements.

On November 27, 2007, our board of directors approved a provisory dividend for U.S.$0.95 per share, which was distributed on
December 12, 2007 and charged to net income. On April 22, 2008, our shareholders approved a final dividend for 2007, which was distributed on May 7, 2008. On November 25, 2008, our board of directors approved a provisory dividend
for U.D.$0.89 per share, which was distributed on December 10, 2008 and charged to net income. On April 23, 2009, our shareholders approved a final dividend for 2008, which was distributed on May 7, 2009. In the aggregate, dividends
distributed equaled 40% of our consolidated net income for 2008, on a Chilean GAAP basis. On November 24, 2009, our board of directors approved an interim dividend of U.S.$0.2294 per share, which was distributed on December 11, 2009 and
charged to net income. On April 27, 2010, our shareholders approved a final dividend of U.S.$0.5016 per share for 2009, which was distributed on May 11, 2010. In the aggregate, dividends distributed equaled 40% of our consolidated net
income for 2009 as determined on an IFRS basis.

Although the board of directors has no current plans to recommend changes in
our dividend policy, the policy has been changed in the past and no assurance can be given that the policy will not be changed in the future, due to changes in Chilean law, capital requirements, operating results or other factors.

ARTICLES OF INCORPORATION AND BY-LAWS

When we refer to the Company, Arauco or we, in this description of the articles of
incorporation and by-laws, we mean Celulosa Arauco y Constitución S.A.

Organization and Registration

We are a corporation (sociedad anónima) organized in Chile under the laws of Chile, and subject to the rules of the Chilean
public corporations (sociedades anónima abiertas) and registered on August 18, 1971, by resolution 300-S of the Chilean Securities Commission and recorded in the Santiago Commercial Register of 1971 on page 6433 under entry number
2994 and on page 6431 under entry number 2993. Notice was published in the Official Gazette on September 4, 1971.

Objects and
Purposes

Our purpose, as stated in our by-laws (estatutos), includes the manufacture of forestry products, the
management of forestry lands and other activities.

Capital

In 2002, our by-laws were amended such that our capital is denominated in U.S. dollars. In 2002, we and two of our subsidiaries,
Aserraderos Arauco and Paneles Arauco, received authorization from the Chilean Internal Tax Service to prepare our audited consolidated financial statements in U.S. dollars, beginning January 1, 2002. In January 1, 2003, our subsidiaries
Forestal Arauco, Bosques Arauco, Forestal Valdivia, Forestal Celco and Cholguán obtained the same permission from the Chilean Internal Tax Service.

Directors

Pursuant to
our by-laws, our board of directors is composed of nine members elected by a general meeting of our shareholders. Our directors are not required to be shareholders. Our by-laws state that the amount of compensation to be received by the directors
for their directorial services shall be fixed by the general shareholders meeting. Directors may be compensated for any non-directorial services rendered to us at levels of compensation comparable with compensation commonly paid for these
services, compensation which is compatible with the directors compensation fixed by the general shareholders meeting. The by-laws also state that our board of directors has all of the authorities of administration and disposal that
Chilean law or the by-laws do not confer upon the general shareholders meeting. The board of directors has the right to act on our behalf without the need for a special power of attorney, even in cases where a power of attorney is required by
law. In particular, the by-laws provide that the board of directors is empowered to encumber our assets, real and personal property with mortgages, easements or pledges regardless of the value of such property or the amount of the respective
encumbrances and to borrow money paying interest, with or without a guaranty for the loan.

Our by-laws provide that we may
enter into acts or contracts in which one or more directors are interested only if the interested directors interest is made known to the board, the acts or contracts are approved by the board and the terms of the act or contract conform to
those prevailing in the market. In addition, board resolutions approving interested director transactions must be reported by the chair of the meeting at the first general shareholders meeting following the approval of the interested director
transaction.

SeeItem 6. Directors, Senior Management and Employees for further information about our
board of directors.

Shareholders

Our share capital consists of ordinary shares of no par value issued in registered form. Record holders of shares are registered in our
share register. Any transfer of shares must be noted in our share register.

Voting Rights

Each share of our stock entitles the holder to one vote at any meeting of shareholders. Resolutions may be taken upon a vote of an
absolute majority of the voting shares present or represented. Any resolution relating to amendments to our by-laws must be approved by an absolute majority of the voting shares issued. Resolutions with regard to the following matters require the
affirmative vote of two-thirds of the voting shares issued:



| |  |  | transformation, including division or merger with another company;
| | - |  | ------------------------------------------------------------------



| |  |  | advanced dissolution;
| | - |  | ---------------------



| |  |  | change of corporate domicile;
| | - |  | -----------------------------



| |  |  | reduction in our equity capital;
| | - |  | --------------------------------



| |  |  | approval and appraisal of non-cash capital contributions;
| | - |  | ---------------------------------------------------------



| |  |  | reduction in the number of members of the board of directors;
| | - |  | -------------------------------------------------------------



| |  |  | the disposal of 50% or more of our assets, whether or not such disposal also includes any of our liabilities; the disposal of 50% or more of the assets
of one our subsidiaries, provided that such subsidiary represents at least 20% of our assets; and any disposal of shares by the company that causes us to lose control of a subsidiary; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes to the way in which corporate benefits will be distributed.
| | - |  | -------------------------------------------------------------------

According to our by-laws, holders of our shares also have the right to vote at the general shareholders meeting for the election of
directors. Shareholders or their representatives may accumulate their votes in favor of one candidate or distribute them among various candidates. A vote on the election of directors may be omitted if an election is proposed by acclamation and none
of the shareholders present or represented opposes the motion. The board of directors may also be dismissed by a regular or special general shareholders meeting, though the shareholders may only vote to dismiss the board as a whole.

Changes to Shareholders Rights

To change the rights of holders of our shares or create a new series of our shares, we must amend our by-laws. Any reduction in the number
of our shares requires a two-thirds majority vote of all holders of our shares under Chilean law. Chilean law also requires that public corporations distribute a cash dividend in an amount equal to at least 30% of the corporations consolidated
net income for each year (on an IFRS basis), unless otherwise decided by a unanimous vote of the corporations issued and subscribed shares eligible to vote. Any changes to the way in which corporate benefits are distributed must be approved by
a two-thirds majority of all holders of the corporations shares.

Shareholders Meetings

Our by-laws provide that the board of directors shall call general shareholders meetings. Notice of general shareholders
meetings must be made by a prominent notice published at least three times, on different days, in the newspaper of one of our corporate domiciles, as determined by a general shareholders meeting, or in the absence of a determination, in the
Official Gazette.

##### Table of Contents

A shareholder must be registered in our share register as of the meeting date to be entitled
to participate and vote at any shareholders meeting. In addition, other persons may represent shareholders at general meetings. Powers of attorney must be given in writing and must be granted with respect to all of the shares the shareholder
is entitled to vote as of the date five days before the general shareholders meeting.

General shareholders
meetings may be regular or special meetings. Regular shareholders meetings are held once a year within the first four months of the year. Among other things, the regular general shareholders meeting appoints independent external auditors
to examine our accounts, inventory, balance sheet and other financial results. The by-laws provide that the following matters are to be considered at regular shareholders meetings:



| |  |  | the review of our results of operations and external auditors reports and the approval or rejection of our annual report, our balance sheet and
financial statements;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the distribution of profits of each financial period and the distribution of our dividends;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | the election or dismissal of the members of the board of directors; and
| | - |  | -----------------------------------------------------------------------



| |  |  | any matter of corporate interest that is not transacted at a special general shareholders meeting.
| | - |  | ---------------------------------------------------------------------------------------------------

Special shareholders meetings may be held at any time required by corporate needs to consider any matter that the law or our
by-laws require to be considered at a general shareholders meeting. Our by-laws require the meeting notice to disclose any matters to be discussed at a special shareholders meeting. According to the by-laws, the following matters must be
considered at special shareholders meetings:



| |  |  | dissolution;
| | - |  | ------------



| |  |  | transformation, merger or division and the amendment of our by-laws;
| | - |  | --------------------------------------------------------------------



| |  |  | the issue of bonds or debentures convertible into shares;
| | - |  | ---------------------------------------------------------



| |  |  | the disposal of 50% or more of our assets, whether or not such disposal also includes any of our liabilities; the disposal of 50% or more of the assets
of one our subsidiaries, provided that such subsidiary represents at least 20% of our assets; and any disposal of shares by the company that causes us to lose control of a subsidiary; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the grant of real or personal guarantees to secure obligations of third parties, unless they are subsidiaries, in which case the approval of the board
of directors will be sufficient.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Any other matters within the competence of general shareholders meetings may be
considered at special shareholders meetings.

Any act of a general shareholders meeting relating to our
dissolution, transformation, merger or division, the amendment of our by-laws, any disposal of 50% or more of our assets or the issue of bonds convertible into shares or convertible debentures must be held before a notary public, who must certify
that the minutes of such meeting are the true expression of what occurred and was resolved at such meeting.

Allocation of Net Income
and Distribution of Dividends

Our by-laws provide that the shareholders at a general shareholders meeting shall
determine the annual distribution of our net profits for each financial period, within the limitations prescribed by law. The shareholders shall also set the date on which any distribution shall be paid, within the time limits prescribed by law.
Chilean law prescribes that distributions shall be paid within 30 days of the general shareholders meeting at which such distribution was determined.

##### Table of Contents

In accordance with Chilean law, in the event of liquidation, capital can be distributed to
the shareholders only after the rights of the creditors have been secured or debts owed to creditors have been paid. Our by-laws provide that a general shareholders meeting will appoint one or more liquidators to carry out the liquidation and
to call shareholders meetings, as required under Chilean law.

Regulation of and Restrictions on Foreign Investors

There are no limitations on the rights to hold securities, including rights of non-resident or foreign shareholders to hold or exercise
voting rights on securities.

Disclosure of Shareholder Ownership

We register certain information about our shareholders in our shareholder registry. We are required to disclose this information to the
Chilean Securities Commission on a quarterly basis.

Rights of Shareholders

Our by-laws provide that, in the case of a dispute between shareholders or between shareholders and management, the parties will submit
their dispute to a mixed arbitrator, who may determine the procedural rules to be used in the arbitration but must issue a final judgment in accordance with Chilean law. Subject to limited exceptions, the arbitrators judgment shall not be
subject to appeal. The parties shall appoint the arbitrator by mutual agreement and if no agreement is reached, an arbitrator will be appointed by the civil court system from among present and former associate justices of the Supreme Court of
Justice of Chile.

EXCHANGE CONTROLS

The Central Bank is responsible for, among other things, monetary policies and exchange controls in Chile. Prior to 1989, Chilean law
permitted the purchase and sale of foreign currency only in cases explicitly authorized by the Central Bank. Law No. 18,840, the Organic Law of the Central Bank of Chile (Ley Orgánica Constitucional del Banco Central de Chile), or
the Central Bank Act, enacted in 1989, liberalized the rules that govern the ability to buy and sell foreign currency.

The
Central Bank Act empowers the Central Bank to determine which types of foreign exchange operations must be carried out in the Formal Exchange Market rather than the Informal Exchange Market (Mercado Cambiario Informal).The
Central Bank has ruled that certain foreign exchange transactions, including those attendant to foreign investments and bond issuances, may be effected only in the Formal Exchange Market. The Central Bank may also impose restrictions on foreign
exchange operations that are conducted or are required to be conducted in the Formal Exchange Market. These restrictions may include the requirement of prior authorization from the Central Bank, the imposition of reserve requirements and the
limitation of foreign exchange operations that may be conducted by the entities that participate in the Formal Exchange Market.

The Formal Exchange Market consists of banks and other entities authorized by the Central Bank to participate in such Formal Exchange
Market. On April 16, 2001, the Central Bank agreed that, effective April 19, 2001, the prior foreign exchange restrictions would be eliminated and a new Compendium of Foreign Exchange Regulations (Compendio de Normas de Cambios
Internacionales) would be applied.

The main objective of this change is to facilitate capital movements from and into
Chile and to encourage foreign investment.

The following specific restrictions were eliminated:



| |  |  | a reserve requirement with the Central Bank for a period of one year;
| | - |  | ---------------------------------------------------------------------



| |  |  | the requirement for prior approval by the Central Bank for certain operations, such as repatriation of investments and payments to foreign creditors;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | the mandatory conversion of foreign currencies into Chilean pesos.

Under the amended regulations, only the following limitations are applicable to these operations:



| |  |  | the Central Bank must be provided with information related to certain operations, such as foreign investments and foreign credits; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | certain operations,such as money transfers to and from Chile related to foreign investments and foreign credits, must be conducted within the
Formal Exchange Market.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

International Issue of Bonds

Before April 19, 2001, any international issue of bonds was subject to approval by the Central Bank after submission of an
application to the Central Bank through a bank or other participant in the Formal Exchange Market. Absent the Central Banks authorization, issuers were unable to offer bonds outside of Chile. On April 19, 2001, the Central Bank issued new
foreign exchange regulations, effective as of March 1, 2002, that were included in the new Chapters XIV and VIII of the Compendium, applicable to bond issues made either from Chile or through an agency abroad. It must be noted however,
that all debt issues made before the new regulations remain subject to the regulations existing at the time of their issue.

Debt
securities issued directly by us

In accordance with regulations issued by the Central Bank, which were included in the
new Chapter XIV of the Compendium, effective March 1, 2002, as amended, any international issue of bonds in an aggregate amount exceeding U.S.$1,000,000 must be registered and dated by the Central Bank or by a bank or other entity
authorized by the Central Bank to participate in the Formal Exchange Market before the proceeds from the issuance can be remitted to Chile and received by the issuer or simultaneously with the remittance into Chile of such proceeds. The issuer must
submit forms regarding the offering to the registering entity or directly to the Central Bank, along with a letter of instructions indicating whether it prefers to receive the proceeds in Chilean pesos or in a foreign currency. If presented through
a Formal Exchange Market entity, such entity must, in turn, verify that the forms submitted by the issuer are in accordance with the documentation relating to the issue and inform the Central Bank of the operation no later than 11:00 a.m. on
the banking business day following the date on which the proceeds of the issue are transferred to the issuer.

If the issuer
opts to receive the proceeds of the issue outside of Chile, it must report this to the Central Bank directly or through a Formal Exchange Market entity during the first ten calendar days of the month following the one in which the proceeds were
received.

Chapter XIV of the Compendium also states that proceeds from the issue, as well as payment of capital and
interest relating to the issue, must be received and sent from and through the Formal Exchange Market, but purchases of U.S. dollars in connection with payments on debt securities issued directly by us can be made either in the Formal or in the
Informal Exchange Market. There can be no assurance, however, that we will be able to purchase U.S. dollars in the Informal Exchange Market or in the Formal Exchange Market at the time or in the amounts required to pay debt service related to any
such debt securities. There can also be no assurance that further Central Bank regulations or legislative changes to the current foreign exchange control regime in Chile would not restrict or prevent our purchase of U.S. dollars to make payments
under our securities.

In the case of debt securities issued directly by us before the effectiveness of the new regulations,
the registration of the debt securities with the Central Bank grants us access to the Formal Exchange Market for the purchase of U.S. dollars necessary to make payments in respect of those securities but requires that payments on such debt
securities shall be made only with U.S. dollars purchased in the Formal Exchange Market.

##### Table of Contents

The regulations of Chapter XIV of the Compendium do not make any reference to the
one-year mandatory deposit in the Central Bank that was previously required by Chapter XIV. However, the Central Bank is authorized, under the Central Bank Act, to impose such a requirement.

Debt securities issued through our Panamanian agency

In December 1996, we established a registered agency in Panama. We may from time to time issue debt securities directly or through our
Panamanian agency depending on, among other factors, whether or not we expect to bring the proceeds thereof into Chile. In such cases, the proceeds of such issuance of the notes may be brought into Chile or held abroad. In either case, however, in
accordance with Chapter VIII of the Compendium, we were required to inform the Central Bank of the issuance of international bonds through our Panamanian agency during the first ten calendar days of the month following the one in which the
disbursement of funds to the agency was produced, and provide the schedule of payments of the notes. On December 27, 2007, the requirement to provide such information to the Central Bank was eliminated. We will no longer be required to inform
the Central Bank of future issuances of bonds made through our Panamanian agency.

Purchases of U.S. dollars in connection
with payments on debt securities issued through our Panamanian agency, whether before or after April 19, 2001, can be made either in the Formal Exchange Market or in the Informal Exchange Market. Although we were required to inform the Central
Bank of the issuance of debt securities through our Panamanian agency, such communication to the Central Bank did not give us access to the Formal Exchange Market for the purchase of U.S. dollars necessary to make payments in respect of those debt
securities.

There can be no assurance that we will be able to purchase U.S. dollars in the Informal Exchange Market or in the
Formal Exchange Market at the time or in the amounts required to pay debt service related to any such debt securities. There can also be no assurance that further Central Bank regulations or legislative changes to the current foreign exchange
control regime in Chile and will not restrict or prevent our purchase of U.S. dollars to make payments under our securities from Chile.

TAXATION

General

The following summary contains a description of the principal Chilean and United States federal income tax consequences of
the purchase, ownership and disposition of our securities, but it does not purport to be a comprehensive description of all the tax considerations that may be relevant to a decision to purchase our securities. This summary does not describe any tax
consequences arising under the laws of any state, locality or taxing jurisdiction other than the United States and Chile.

This summary is based on the tax laws of Chile and the United States as in effect on the date of this Form 20-F, as well as regulations,
rulings and decisions of Chile and the United States available on or before such date and now in effect. All of the foregoing is subject to change, and any changes could apply retroactively and could affect the continued validity of this summary.

Prospective purchasers of our securities should consult their own tax advisors as to the Chilean, United States or other tax
consequences of the purchase, ownership and disposition of our securities, including, in particular, the application to their particular situations of the tax considerations discussed below, as well as the application of state, local, foreign or
other tax laws.

Chile and the United States have executed an income and capital tax treaty for the avoidance of double
taxation and the prevention of fiscal evasion, but this treaty is not in effect, and its effectiveness is contingent upon ratification in the United States Senate and by the Chilean Congress. At this time it is not clear when the United States
Senate and the Chilean Congress will consider ratification, and therefore the effective date of the treaty is uncertain.

Chilean Taxation

The following is a general summary of the principal consequences under Chilean tax law, as currently in effect, of an investment in our
securities made by a foreign holder. Foreign holder means either:



| |  |  | in the case of an individual, a person who neither is a resident nor is domiciled in Chile. For Chilean tax purposes, an individual is domiciled in
Chile if such individual has his or her principal place of business in Chile. The individual will be considered as a resident if she or he stays in Chile for more than six months in one calendar year or a total of more than six months in two
consecutive fiscal years; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in the case of a legal entity, a legal entity that is not organized under the laws of Chile, unless our securities are assigned to a branch or a
permanent establishment of such entity in Chile.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under Chiles income tax law, our payments of
interest made from Chile in respect of our securities to a foreign holder will generally be subject to a Chilean withholding tax assessed at a rate of 4.0% (the Chilean Interest Withholding Tax).

We have agreed, subject to specific exceptions and limitations, to pay to the foreign holders of notes additional amounts in respect of
the Chilean Interest Withholding Tax in order to ensure that the interest amount the foreign holder receives is net of Chilean Interest Withholding Tax. If we pay additional amounts in respect of the Chilean Interest Withholding Tax, any tax refunds
in respect of these amounts will be for the benefit of the company. In the event that certain changes in Chilean tax laws require us to pay additional interest amounts in respect of the Chilean Interest Withholding Tax at a rate in excess of 4.0%,
we have the right to redeem our securities.

Under existing Chilean law and regulations, a foreign holder will not be subject
to any Chilean taxes in respect of payments of principal that we make with respect to our securities. Our payments with respect to our securities of amounts not considered principal or interest may be subject to a Chilean withholding tax of up to
35%.

The Chilean Income Tax Law provides that a foreign holder is subject to income tax on his Chilean source income. For
this purpose, Chilean source income means earnings from activities developed in Chile or goods located in the country. According to the Chilean Income Tax Law, the source of interest income corresponds to the residence country of the debtor. Under
these rules, the capital gain realized on the sale or other disposition by a foreign holder of our securities will be generally subject to taxes on capital gain.

A foreign holder will not be liable for gift, inheritance or similar taxes with respect to its holdings unless the securities held by a
foreign holder:



| |  |  | are located in Chile at the time of such foreign holders death, or
| | - |  | -------------------------------------------------------------------



| |  |  | are located outside of Chile, but were purchased or acquired with funds derived from Chilean source income.
| | - |  | -----------------------------------------------------------------------------------------------------------

A foreign holder should not be liable for Chilean stamp, registration or similar taxes.

The issue of our securities directly by us was subject to the Chilean stamp tax, which we paid. The issue of our securities through our
Panamanian Branch was not subject to a stamp tax.

United States Taxation

This summary of certain United States federal income tax considerations deals principally with United States Holders that acquired our
securities as part of the initial offering of our securities, hold our securities as capital assets and whose functional currency is the United States dollar. It does not purport to be a comprehensive description of all of the tax considerations
that may be relevant to a particular investor, and generally does not address the tax treatment of United States Holders that may be subject to special tax rules, such as banks, financial

##### Table of Contents

institutions, tax-exempt entities, regulated investment companies, real estate investment trusts, insurance companies, dealers in securities or currencies, traders in securities electing to mark
to market, certain short-term holders of our securities, persons that will hold our securities as a position in a straddle or conversion transaction, or as part of a synthetic security or other integrated financial
transaction, persons that own (or are deemed to own for United States tax purposes) 10% or more of our voting stock or persons that are not United States Holders. United States Holders should be aware that the U.S. federal income tax consequences of
holding our securities may be materially different for investors described in the previous sentence, including as a result of certain laws applicable to investors with short holding periods or that engage in hedging transactions.

As used under this section United States Taxation, the term United States Holder means a beneficial owner of a
Note that is a citizen or resident of the United States or a United States domestic corporation or that otherwise is subject to United States federal income taxation on a net income basis in respect of our securities.

Taxation of Interest and Additional Amounts

A United States Holder will treat the gross amount of interest and Additional Amounts (i.e., without reduction for Chilean Interest
Withholding Tax, determined utilizing the 4.0% Chilean Interest Withholding Tax rate applicable to all United States Holders of our securities) as ordinary interest income in respect of our securities at the time that such payments are accrued or
are received, in accordance with the United States Holders method of tax accounting. Any Chilean Interest Withholding Tax paid will be treated as foreign income taxes eligible for credit against such United States Holders United States
federal income tax liability, subject to generally applicable limitations and conditions, or, at the election of such United States Holder, for deduction in computing such United States Holders taxable income. Interest and Additional Amounts
will constitute income from sources outside the United States for foreign tax credit purposes. Such income generally will constitute passive category income. Foreign tax credits will not be allowed for withholding taxes imposed in
respect of certain short-term or hedged positions in securities and may not be allowed for withholding taxes imposed in respect of arrangements in which a United States Holders expected economic profit is insubstantial. United States Holders
should consult their own advisors concerning the implications of these rules in light of their particular circumstances.

The
calculation of foreign tax credits and, in the case of a United States Holder that elects to deduct foreign taxes, the availability of deductions, involves the application of rules that depend on a United States Holders particular
circumstances. United States Holders should consult their own tax advisors regarding the availability of foreign tax credits and the treatment of Additional Amounts.

A Holder of our securities that is, with respect to the United States, a foreign corporation or a nonresident alien individual (a
Non-U.S. Holder) generally will not be subject to United States federal income or withholding tax on interest income or Additional Amounts earned in respect of our securities, unless such income is effectively connected with the conduct
by the Non-U.S. Holder of a trade or business in the United States.

Taxation of Dispositions

Gain or loss realized by a United States Holder on the sale, redemption or other disposition of our securities generally will be treated
as capital gain or loss and such gain or loss will be long-term capital gain or loss if at the time of the disposition, our securities have been held for more than one year. The net amount of long-term capital gain realized by a United States Holder
that is an individual is generally taxed at a reduced rate. Gain, if any, realized by a United States Holder generally will be treated as U.S. source income for U.S. foreign tax credit purposes.

A Non-U.S. Holder of our securities will not be subject to United States federal income or withholding tax on gain realized on the sale
or other disposition of our securities unless (i) such gain is effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States or (ii) in the case of gain realized by an individual Non-U.S. Holder,
the Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met.

Backup Withholding and Information Reporting

Payments of principal, premium, if any, and interest on our securities and payment of the proceeds of any disposition of our securities
made to certain United States Holders may be subject to U.S. information reporting requirements. In addition, certain United States Holders may be subject to a U.S. backup withholding tax in respect of such payments if they do not provide their
taxpayer identification numbers to the payor or otherwise establish an exemption. Non-U.S. Holders generally are exempt from these withholding and reporting requirements, but may be required to comply with applicable certification and identification
procedures to establish their eligibility for such an exemption.

from changes in interest rates and currency exchange rates. From time to time, we assess our exposure and monitor opportunities to manage these risks, including entering into derivative contracts. In the normal course of business, we also face risks
that are either non-financial or non-quantifiable. Such risks principally include country risk, credit risk and legal risk and are not represented in the tables below.

INTEREST RATE RISK

Interest rate risk exists principally with respect to our indebtedness that bears interest at floating rates. At December 31, 2009,
we had outstanding approximately U.S.$3,022.4 million of long-term indebtedness excluding accrued interest, of which approximately 87.2% bore interest at fixed interest rates and approximately 12.8% bore interest at floating rates of interest. These
average rates do not reflect the effect of swap agreements. 86.2% of the indebtedness was denominated in U.S. dollars as of that date. The interest rate on our variable rate debt is determined principally by reference to LIBOR.

The following table summarizes our long-term debt obligations, including 2010 maturities, at December 31, 2009 that are sensitive to
changes in interest rates. The table presents the aggregate principal amount of each category of indebtedness maturing in each year, at the weighted average interest rate for each category of indebtedness. Average interest rates for liabilities are
calculated based on the prevailing interest rate for each loan at December 31, 2009.

FOREIGN CURRENCY RISK

Our principal exchange rate risk involves changes in the value of the Chilean peso and, to a lesser extent, the Brazilian real, the euro
and the Argentine peso relative to the dollar. We generally believe that our foreign currency exposure is not material to our net income. In 2009, substantially all of our consolidated revenues were denominated in or indexed to foreign currencies.
We estimate that a majority of our consolidated costs and expenses are denominated in dollars. As of December 31, 2009:



| |  |  | 70% of our accounts receivable were denominated in U.S. dollars and a 19% in Chilean pesos;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | 34% of our cash and short-term investments were denominated in U.S. dollars, 41% were denominated in Chilean pesos and 12% in euros;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | substantially all of our indebtedness was denominated in U.S. dollars; and
| | - |  | --------------------------------------------------------------------------



| |  |  | a significant portion of our consolidated total assets was denominated in U.S. dollars.
| | - |  | ---------------------------------------------------------------------------------------

Substantially all of our foreign currency-denominated revenues, costs and expenses, receivables and indebtedness are denominated in U.S.
dollars. As of December 31, 2009, substantially all of our long-term debt was denominated in U.S. dollars.Accordingly, variations in the value of the Chilean peso relative to the dollar will not have a significant effect in the cost in
dollars of our foreign debt service obligations.

|Item 15T. | Controls and Procedures
|--------- | -----------------------

(a) Disclosure controls and procedures.We carried out an evaluation under the supervision and with the
participation of our management, including our Chief Executive Officer and Chief Accounting Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as of December 31, 2009. There are inherent
limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective controls and procedures
can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Accounting Officer concluded that the disclosure controls and procedures, as of December 31, 2009,
were effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the U.S. Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time
periods specified in the Commissions rules and forms and that such information is accumulated and communicated to the Companys management, including its Chief Executive Officer and Chief Accounting Officer, as appropriate to allow timely
decisions regarding required disclosure.

(b) Managements annual report on internal controls and procedures.Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Under the
supervision and with the participation of our management, including our Chief Executive Officer and Chief Accounting Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in
Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Based on our
evaluation under the framework in Internal ControlIntegrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2009.

(c) Attestation Report of the registered public accounting firm.This annual report
does not include an attestation report of the Companys registered public accounting firm regarding internal control over financial reporting pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to

(d) Changes in internal controls over
financial reporting.There has been no change in our internal control over financial reporting during 2009 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.



|Item 16A. | Audit Committee Financial Expert
|--------- | --------------------------------

We do not have an audit committee. Accordingly, certain rules under the U.S. federal securities laws that would otherwise apply to the
audit committee apply to our board of directors as a whole. We believe that the members of our board of directors have sufficient financial and other experience to perform their responsibilities under these rules. Our board of directors has
determined that Timothy C. Purcell qualifies as an audit committee financial expert within the meaning of Item 16A of Form 20-F. Our board of directors has determined that Timothy C. Purcell is independent as that term is defined in
Rule 10A-3 under the Exchange Act. For a description of Mr. Purcells professional experience, see Item 6. Directors, Senior Management and EmployeesDirectors and Executive Officers.



|Item 16B. | Code of Ethics
|--------- | --------------

We have adopted a code of ethics, as defined in Item 16B of Form 20-F under the Securities Exchange Act of 1934,
as amended. Our code of ethics applies to all of our employees, including, but not limited to, our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer. We will provide any person without charge, upon request, a copy of such
code of ethics. Requests for a copy of the code of ethics may be made to Celulosa Arauco y Constitución S.A., El Golf 150,

Accounting Officer, or if we grant any waiver of such provisions, we will disclose the amendment or waiver in our annual report on Form 20-F.

Report of
Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

Celulosa Arauco y Constitución S.A.

In
our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, comprehensive income, shareholders equity and cash flows present fairly, in all material respects, the financial position of Celulosa
Arauco y Constitución S.A. and its subsidiaries at December 31, 2009 and 2008, and January 1, 2008 and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2009 in
conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on
these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Functional Currency

Arauco has defined the U.S. Dollar as its main functional currency, as most of the Companys operations are a result of exports,
and its costs to a large extent are related to or index-linked to the U.S. Dollar.

For the pulp segment, most of the sales
operations are exports, and the costs are related mainly to plantation costs, which are settled in U.S. Dollars.

For the
sawmill and panel segments, although total sales include a mix of domestic sales and exports, the prices for the products are established in U.S. Dollars, as is also the case for the cost structure of the related raw materials.

Although the costs of labor and services are generally billed and paid in local currency, these costs are not as significant as the cost
of raw materials and depreciation of equipment, which are driven by the global market and therefore, are influenced mostly by the U.S.Dollar.

The financial information included herein is presented in thousands of U.S. Dollars without decimals.

All significant information required by International Financial Reporting Standards (IFRS), as issued by the International
Accounting Standard Board (IASB), is presented in these consolidated financial statements.

Additional Information Relevant to
the Understanding of the Consolidated financial statements

The company Fondo de Inversión Bío Bío and
its subsidiary Forestal Río Grande S.A. are entities that qualify as Special Purpose Entities. However, they are controlled by Arauco, which is determined, in part, by the fact that they maintain exclusive contracts with Arauco for wood
provision, forward purchase of land and forest administration. Consequently, the financial information of these companies is consolidated with the financial information of the Company and is included in these consolidated financial statements of
Arauco.

Compliance and Adoption of IFRS

The accompanying consolidated financial statements of Arauco include the balance sheet, statements of income from operations and cash
flows in accordance with IFRS.

This presentation is required to give a faithful representation of the effects of
transactions, as well as other events and conditions, according to the definitions and criteria established within the conceptual framework of IFRS for the recognition of assets, liabilities, income and expenses.

IFRS Compliance Declaration

These consolidated financial statements were prepared in accordance with International Financial Reporting Standards (IFRS),
as issued by the International Accounting Standard Board (IASB), and represent the wholesale adoption, explicitly and without reservation of the mentioned international standards.

The nature of external capital requirements is
determined by the obligation to maintain certain financial ratios that ensure compliance with either bank loans or bond payments, which provide guidelines on the capital ranges required for compliance with these requirements.

Arauco has fulfilled all its external requirements.

Arauco considers it unlikely that future uncertainty risks will result in any significant adjustment to the book value of assets and
liabilities within the next financial period. In the case of the fair value of biological assets, no risks are foreseen in which the value of forests will change significantly. Notably, the data used to make the foregoing determination contemplates
the long-term realization of such risks, and therefore the estimates provided are also relevant for the long term.

Summary of significant
accounting policies

The accompanying consolidated financial statements as of December 31, 2009 were prepared in
accordance with current IFRS accounting policies, uniformly applied to all items in these consolidated financial statements.

a) Basis for
Presentation of financial information

The consolidated financial statements have been prepared under the historic cost
convention, as modified for the revaluation of biological assets, financial assets and financial liabilities (including derivative instruments) at fair value through profit and loss.

b) Critical accounting estimates and judgments

The preparation of consolidated financial statements in accordance with IFRS requires management to make subjective estimates and
assumptions that affect the amounts reported. Estimates are based on historical experience and various other assumptions that are believed to be reasonable, though actual results and timing could differ from the estimates. Management believes that
the accounting policies below take into account those matters that require the exercise of judgment, but acknowledge that different judgments could result in substantially different results.

- Property, Plant and Equipment

The carrying amounts of fixed assets are reviewed whenever events or changes in circumstances indicate that the carrying amount of an
asset may be impaired. The recoverable amount of an asset is estimated as the higher of fair value less the cost to sell and the value in use, with an impairment charge being recognized whenever the carrying amount exceeds the recoverable amount.
The value in use is calculated using a discounted cash flow model, which is most sensitive to the discount rate as well as the expected future cash inflows.

- Fair Value of Financial Instruments

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. Arauco uses
its judgment to select a variety of methods and make assumptions that are mainly based on market conditions existing at each balance sheet date.

-Biological Assets

The
recovery of forest plantations is based on discounted cash flow models which means that the fair value of biological assets is calculated using cash flows from continuing operations on a discounted basis, on our sustainable forest management plans
and the estimated growth of forests. This recovery is performed on the basis of each stand identified and for each type of tree species.

These discounted cash flows require estimates in growth, harvest, sales prices and costs. It is therefore important that management make
appropriate estimates of future levels and trends for sales and costs, as well as conduct regular surveys of the forests to establish the volumes of wood available for harvesting and their current growth rates. The principal considerations used to
calculate the valuation of forest plantations are presented in Note 21.

-Lawsuits and Contingencies

Arauco and its subsidiaries are subject to lawsuits in process, whose future effects need to be estimated by the management of the
Company, in collaboration with its legal advisers. Arauco seeks to interpret the reports of its legal advisers and make appropriate contingency estimates in each balance sheet and/or upon each substantial modification to an underlying cause of any
such litigation.

c) Consolidation

The consolidated financial statements include all entities over which Arauco has the power to govern the financial and operating policies,
usually accompanying a shareholding of more than one half of the voting rights. Subsidiaries are fully consolidated from the date on which control is transferred to the group. They are de-consolidated from the date that control ceases.

Unrealized earnings from subsidiary operations have been eliminated from the consolidated financial statements and minority shareholder
equity is recognized in the equity balance.

The consolidated financial statements for the year ended December 31, 2009
include subsidiary balances shown in Note 13 and balances of the Fondo de Inversión Bío Bío balances, and its subsidiary Forestal Río Grande S.A., both of which qualify as Special Purpose Entities.

Some consolidated subsidiaries report legal financial statements in Brazilian Reales and
Chilean Pesos. For consolidation purposes, they have been translated as indicated in Note 11.

d) Segments

Arauco has defined its operating segments according to its business areas, which are defined by products and services sold to customers.
This is consistent with the management, resource allocation and performance assessment made by key personnel responsible for making such relevant decisions related to the Companys operation. The Chief Executive Officer and Corporate Managing
Directors of each segment are responsible for these decisions. Detailed financial information by segment is presented in Note 24.

e)
Functional currency

(i) Functional currency

Araucos entities are measured using the currency of the primary economic environment in which the Company operates (the functional
currency). The consolidated financial statements are presented in U.S. Dollars, which is the Companys functional currency and Araucos presentation currency.

(ii) Foreign Currency Translations  Subsidiaries and Associates

The income statements of subsidiaries, whose functional and presentational currencies are not the U.S. Dollar, are translated into
the Arauco reporting currency using the average monthly exchange rates, whereas the balance sheets of such subsidiaries are translated using the exchange rates at the reporting date. Exchange differences arising from the retranslation of net
investments in foreign entities are recorded directly in shareholders equity as Conversion reserves, as shown in the consolidated statement of changes in equity. The cumulative translation differences of divestments and liquidations are
combined with their gain or loss on disposal.

(iii) Foreign Currency Transactions

Transactions in foreign currencies are recorded at the rate of exchange prevailing at the transaction date. Gains and losses on foreign
currency resulting from the settlement of such transactions and from the conversion at the closing exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement, except that which matches
the deferral in net equity, such as those derived from cash flow hedges.

f) Cash and cash equivalents

Cash and cash equivalents include cash-in-hand, deposits held on call at banks and other liquid investments with an original maturity of
less than three months.

g) Financial Instruments

(i) Financial assets-liabilities at fair value through profit or loss

Financial assets at fair value through profit or loss are financial assets held for trading. A financial asset is classified in this
category if it is acquired principally for the purpose of selling in the short term.



F - 14



---

##### Table of Contents

LOGO



Derivatives are also classified as acquired for trading unless they are designated as
hedges. Assets in this category are classified as current assets and the obligation for these instruments is presented under Other financial liabilities within the Financial Statement.

Regular purchases and sales of financial assets are recognized on the trade-date, which is the date on which the Company commits to
purchase or sell the asset.

The financial assets and liabilities carried at fair value through profit or loss are initially
recognized at fair value and transaction costs are expensed in the income statement. They are subsequently recorded at fair value with the effect of the change in value recorded in income.

(ii) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market.
They are included in current assets, except for maturities greater than 12 months from the balance sheet date, which are classified as non-current assets. Loans and receivables include trade receivables and other receivables.

Loans and receivables are initially recorded at fair value and subsequently at amortized cost according to the effective interest rate
method. A provision of bad debts is recorded to reflect uncollective amounts.

(iii) Financial liabilities valued at amortized cost (loans)

Loans, bond obligations and liabilities of a similar nature are recognized initially at fair value, net of transaction costs
incurred. In subsequent periods, they are stated at amortized cost and any difference between proceeds (net of transaction costs), and redemption value is recognized in the income statement over the life of the debt according to the effective
interest rate method.

Financial obligations are classified as current liabilities unless the Company has an unconditional
right to defer settlement for at least 12 months after the balance sheet date.

(iv) Creditors and other payables

These instruments are initially recorded at fair value and subsequently at amortized cost using the effective interest rate method.

(v) Hedging instruments

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in
Other Comprehensive Results. The gain or loss relating to the ineffective portion is recognized immediately in the Income Statement within Other Operating Income or Operating Expenses, respectively.

When a hedging instrument expires or is sold, or when it ceases to meet the criteria to be recognized through the hedge accounting
treatment, any cumulative gain or loss in equity at that time remains in equity and is recognized in the Income Statement. When a possible transaction is no longer expected to occur, the cumulative gain or loss in equity is immediately transferred
to the Income Statement.

h) Inventories

Inventories are reported at the lower of cost or net realizable value. Cost is determined using the weighted average cost method.

The cost of finished goods and work in progress includes the cost of raw materials, direct labor, other direct costs and
general manufacturing expenses, excluding interest expenses.

Initial costs of harvested wood are determined at fair value
less cost of sale at the point of harvest.

Biological assets are transferred to inventories when forests are harvested.

Net realizable value is the estimated selling price in the normal course of business, less cost of sale.

When market conditions result in the manufacturing costs of a product exceeding its net realizable value, a valuation allowance is made.
This provision also includes obsolescence amounts resulting from slow moving inventories and technical obsolescence.

i) Business
Combinations

Business combinations are recognized using the purchase method. This involves recognizing identifiable assets
(including previously unrecognized intangible assets) and liabilities (including contingent liabilities and excluding future restructuring) of the acquired business at fair value.

The goodwill acquired in a business combination is initially measured at the cost of the business combination less the interest of the
company in the net fair value of assets, liabilities and contingent liabilities of the acquisition. After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For purposes of impairment testing, goodwill acquired
in a business combination is allocated as of the acquisition date to the cash generating unit of the group or groups of cash generating units expected to benefit from the synergies of the combination without prejudice to whether other assets or
liabilities of Arauco are assigned to those units or groups of units. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in the income statement as Negative
goodwill immediately recognized.

Arauco measures the fair value of the acquired company in the business combination on a step
by step basis, recognizing the effects of variation in the income statement in the period in which they occur.

Accounting
policies for subsidiaries will be adjusted if necessary to ensure consistency with the policies adopted by Arauco. Minority Interests are presented as a separate component of equity.

j) Investments in associates

Associates are entities over which Arauco exercises significant influence but not control, generally holding between 20 and 50% of the
voting rights. Investments in associates are accounted for using the equity method and are initially recognized at cost. Their book net equity is increased or decreased proportionately in the income statement and comprehensive income statement of
the period as a result of adjustments of conversion arising from the financial statement conversion into other currencies. Araucos investment in associates includes goodwill (net of any accumulated impairment loss).

k) Intangible assets



|(i) | Computer Software
|--- | -----------------

Computer
software programs are capitalized in terms of the costs incurred to make them compatible with specific programs. These costs are amortized over their estimated useful lives.

(ii) Goodwill

The excess of
the cost of acquisition over the fair value of the groups share of the identifiable net assets acquired is recorded as goodwill. Goodwill is not amortized but is tested for impairment on an annual basis.

(iii) Water-rights

Water-rights are recognized at historical cost and have an unlimited useful life as the expected cash flow generating period is
unpredictable. These rights are not amortized as they are perpetual and will not require renewal, but are subject to annual impairment tests.

l) Property, plant and Equipment

Property, plant and equipment are stated at historical cost less depreciation and accumulated impairment losses. Historical cost includes
expenditures that are directly attributable to the acquisition.

Subsequent costs are included in the assets carrying
amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the group and the cost of the item can be measured reliably.

Asset depreciation is calculated using the straight-line method, considering any adjustments for impairment.

The useful life of property, plant and equipment is determined according to expected use of the assets.

The assets residual values and useful lives are reviewed, and adjusted if appropriate, on an annual basis.

m) Leases

Fixed asset
leases in which Arauco substantially holds all ownership risks and advantages are classified as finance leases. Finance leases are capitalized at the leases commencement at the lower of the fair value of the leased property and the present
value of the minimum lease payments.



F - 17



---

##### Table of Contents

LOGO



Leases in which significant risks and rewards are not transferred to the lessee are
classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are charged to the income statement on a straight-line basis over the period of the lease.

n) Biological Assets

IAS 41 requires that biological assets, such as standing trees, are shown on the Balance Sheet at fair value. The forests are thus
accounted for at fair value less estimated point-of sale costs at harvest, assuming that the fair value of these assets can be measured reliably.

The valuation of forest plantations assets is based on discounted cash flow models whereby the fair value of the biological assets is
calculated using cash flows from continuous operations, which are discounted based on our sustainable forest management plans and the estimated growth of the forests. This valuation is performed on the basis of each identifiable farm block basis and
for each type of tree.

Forest plantations shown as current assets are those that will be harvested and sold in the short
term.

Biological growth and changes in fair value are recognized in the income statement within Other operating income.

o) Deferred income tax

Deferred income tax is recognized using the liability method, on temporary differences arising between the tax bases of assets and
liabilities and their carrying amounts in the consolidated financial statements. However, the deferred income tax is not accounted for if it arises from the initial recognition of an asset or liability in a transaction other than a business
combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted as of the balance sheet date that are expected to apply when
the related deferred income tax asset or the deferred income tax liability is settled.

The deferred income tax assets are
recognized to the extent that it is probable that future taxable benefits profit will be available against which temporary differences can be utilized.

p) Provisions

Provisions are recognized when the Company has a current legal or constructive obligation as a result of past events; it is probable that
an outflow will be required to settle the obligation; and the amount has been reliably estimated. This amount is quantified with the best possible estimate at the end of each period.

q) Revenue recognition

Revenues are recognized after Arauco has transferred the risks and rewards of ownership to the buyer and Arauco retains neither a
continuing right to dispose of the goods, nor effective control of those goods; this means that revenues are recorded upon delivery of goods to customers in accordance with agreed terms of delivery.

Segment revenues mentioned in Note 24 comply with the conditions indicated above.



F - 18



---

##### Table of Contents

LOGO



Revenues from inter-segment sales (which are made at prices that approximate market
prices) are eliminated in the consolidated financial statements.

r) Minimum dividend

Article No. 79 of the Privately Limited Companies Law of Chile provides that, unless otherwise unanimously agreed or adopted by the
shareholders, a dividend must be distributed annually in cash to shareholders in proportion to their shares or in the proportion established by the statutes if any preferred shares, in the amount of at least 30% of net profits for the current year,
except where necessary to absorb accumulated losses from prior years.

The General Shareholders Meeting of Arauco
resolved to maintain annual dividends at 40% of net distributable profit, including a provisional dividend share distribution at year-end. Dividends payable are recognized as a liability in the financial statements in the period they are declared
and approved by the Companys shareholders or when configuring the corresponding obligation on the basis of existing legislation or distribution policies established by the Shareholders Meeting.

The interim and final dividends are recorded in equity upon their approval by the relevant groups, which include the Companys Board
and the shareholders.

The amount of these dividends is presented in these consolidated financial statements under Other
Current Liabilities.

s) Impairment

Non-financial Assets

The
carrying amounts of property, plant and equipment are subject to impairment tests whenever some event or change in business circumstances indicates that the book value of assets may not be recoverable, whereas goodwill is tested annually. The
recoverable amount of an asset is estimated as the higher of net selling price and value in use. An impairment loss is recognized whenever the carrying amount exceeds the recoverable amount.

A previously recognized impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount,
however, not to an extent higher than the carrying amount that would have been determined and recognized in prior years. For goodwill, however, a recognized impairment loss is not reversed.

Goodwill is allocated to cash-generating units for the purpose of impairment testing. The allocation is made to those cash-generating
units or groups of cash-generating units that are expected to benefit from the business combination in which the goodwill arose.

Cash-generating units are the smallest identifiable groups of assets whose use generates continuous funds largely independent
of those produced by the use of other assets or groups of assets.

Goodwill is allocated to cash-generating units for the
purpose of impairment testing. The distribution is made between cash-generating units or groups of cash generating units expected to benefit from the business combination that resulted in the goodwill.

Financial Assets

At the end of each period, an evaluation is performed in order to measure the existence of any objective evidence that assets or a group
of financial assets have been adversely affected. Impairment effects will be recognized in the Consolidated Income Statement only if there is objective evidence that one or more events will occur after initial recognition of financial asset
impairment and if these events will affect associated future cash flows.

The provision for doubtful trade receivables is
established when there is evidence that Arauco will not receive payments under the original terms of sale. Provisions are made when the client is a party to a bankruptcy court agreement or cessation of payments, or when Arauco has exhausted all
levels of recovery of debt in a reasonable time. In the case of sales of our Chilean distribution subsidiary (Arauco Distribución S.A.), provisions are estimated using a percentage of accounts receivable to be determined on a case by case
basis depending on the internal classification of customer risk and age of the debt (days overdue).

t) Employee Benefit Costs

The Company has severance payment obligations. These are paid to certain workers according to conditions established
within collective or individual contracts.

Actuarial gains and losses are recognized in income in the year they are incurred.

These obligations are treated as post-employment benefits in accordance with current standards.

u) Employee Vacations

Arauco recognizes the expense for employee vacation on an accrual basis and the expense is recorded at nominal value.

This obligation is presented in the Consolidated Balance Sheet in the line Trade payables and Other payables, current.

v) Joint Venture Equity

Joint venture equity is recognized using the equity method. On acquisition, any excess of Araucos share of the net fair value of the
associates identifiable assets and liabilities over the cost of the investment is included as income in the determination of Araucos share of the associates profit or loss in the period in which the investment is acquired.

Description of adjustments

(a) Property, plant and equipment adjustment

The Company has applied the fair value as deemed cost exemption to pulp plants, land, buildings, and equipment owned in both Arauco and
Constitución in Chile, Misiones in Argentina, and the panel plant and sawmill in Brazil. This adjustment increased equity. As a result of this change in value, and the modification of their useful life and residual values of these assets,
depreciation for the period was also impacted. Further, given the fact that depreciation is included within the cost of inventories, this cost was also modified.

The fair value of the assets, where the fair value as deemed cost method was applied, amounted to ThU.S.$ 1,526,822 at January 1,
2008.

(b) Consolidation of special purpose entities

Under IFRS, as determined by IAS 27 Consolidated and separate financial statements and SIC 12 Consolidation  special purpose
entities, Arauco consolidated the assets and liabilities of Fondo de Inversión Bío Bío and its subsidiary Forestal Río Grande S.A. because it was determined that control exists even when there is no percentage of
participation in the property of such entities, unlike the requirements of Chilean GAAP. The consolidation of this entity had an impact on equity. The assets and liabilities assumed include the following:

(c) Biological assets adjustment

Management decided that future cash flows shall be the criteria to be used to determine the fair value of biological assets under IFRS.
This differs from criteria used under Chilean GAAP where biological assets were valued using standard commercial margins for forests with harvesting volume and plantation costs for biological assets with no harvesting volume.

Under IFRS, biological growth is recognized within the income statement, impacting earnings at each ending period. Furthermore, given the
change in the value of biological assets, the cost of inventories has also been impacted.

(d) Functional currency adjustment

This adjustment is comprised of the following:

|(i) | The Company determined that the functional currency for the majority of the its subsidiaries is the U.S. Dollar, and proceeded to convert all its non-monetary
assets and liabilities, particularly those related to Property, plant and equipment, to U.S. Dollars, using historical exchange rates at the time of the construction or acquisition of the assets.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(ii) | The Brazilian Real was determined to be the functional currency for subsidiaries in Brazil. Under Chilean GAAP these companies used the U.S. Dollar as their
functional currency. For this reason, the subsidiaries in Brazil adjusted their assets, liabilities, equity and results from historical U.S. Dollars to historical Reales. This change in functional currency has an impact on the accumulated
translation differences account within equity and on the determination and conversion of the results of the period.
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(e)
Negative goodwill adjustment

Under Chilean GAAP, negative goodwill was recorded within the balance sheet and amortized to
profit and loss. Under IFRS, negative goodwill is recorded in income. Accordingly, at the transition date previously recorded negative goodwill was adjusted against the accumulated results.

(f) Minimum dividend adjustment

Article No. 79 of the Private Limited Companies of Chile Act provides that, unless otherwise unanimously agreed or adopted by the
shareholders, shares-stock as a dividend must distribute annually in cash to shareholders, in proportion to their shares or in the proportion established by the statutes if any preferred shares, at least 30% of net profits for the current year,
except where necessary to absorb accumulated losses from prior years.

The General Shareholders Meeting of Arauco
resolved to maintain the dividend at 40% of net distributable profit.

|(i) | This derivative is recorded as a hedging instrument under Chilean GAAP. However, under IFRS hedge accounting has not been applied and, therefore this derivative has
been recorded within earnings.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Assets and liabilities at fair value through profit or loss at January 01,
2008 correspond to derivative contracts and mutual funds. The fair value amount of these instruments is detailed in the first table of Note 23. Chilean GAAP considers the derivative instruments as hedging instruments for existing items and expected
transactions. Derivatives of existing items were recognized in results when they involve a loss and in liability if they involved an unrealized profit. Expected derivative transactions were directly recorded in results (realized and unrealized).
Investments in mutual funds are valued at the respective value of shares at the closing date of each year, which does not generate differences to fair value under IFRS.

|(iii) | Under Chilean GAAP, interest is accrued using the nominal interest rate. Under IAS 39 Financial instruments: recognition and measurement, financial liabilities not at
fair value through profit and loss must be valued using the effective interest method.

|(ii) | Under Chilean GAAP, all temporary differences arising prior to the year 1999 were recorded against complementary accounts. These accounts would then reverse
when the related temporary difference would reverse. Under IFRS, these complementary accounts are not allowed and, therefore must be adjusted against retained earnings.

Adjustments caused by subsidiaries and affiliates using a functional currency different from the U.S. Dollar and due to adjustments in associates caused by variations in associates equity. Under Chilean GAAP these results were only reported as
equity variations and were not part of the Income Statement.

Description of adjustments

(a) Property, plant and equipment adjustment

The Company has applied the fair value as deemed cost exemption to pulp plants, land, buildings, and equipment owned by both Arauco and
Constitución in Chile, Misiones in Argentina, and the panel plant and sawmill in Brazil. This adjustment increased equity. As a result of this change in value, and the modification of their useful life and residual values, depreciation for
the period was also impacted. Further, given the fact that depreciation is included within the cost of inventories, this cost was also modified.

The fair value of the assets, where the fair value as deemed cost method was applied, amounted to ThU.S.$ 1,526,822 at January 1,
2008.

(b) Biological assets adjustment

Management decided that future cash flows shall be the criteria to be used to determine the fair value of biological assets under IFRS.
This differs from the criteria used under U.S. GAAP, which values biological assets at historical cost.

Under IFRS,
biological growth is recognized within the income statement, impacting earnings at each ending period. Further, given the change in the value of biological assets, the cost of inventories has also been impacted.

(c) Investment in associates through equity method

Due to the adoption of IFRS by companies in which Arauco has investments, the net equity of these companies changed. Correspondingly, the
respective net equity values of these investments were adjusted.

(d) Deferred tax adjustment

This refers to deferred taxes arising from assets and liabilities adjustments to IFRS, which constitute a temporary difference between
financial basis and taxable basis. The main components are the following:



|                                                                         |  |            |   |  |            |

|Total                                                                    |  | (691.880   | ) |  | (721.302   | )
|                                                                         |  |            |   |  |            |  

(e) Impairment in property, plant and equipment Brazil

This refers to a reverse of an impairment loss on property, plant and equipment in Brazil, since, as stated in subsection a), the fair
value as deemed cost exemption was applied with respect to the land, buildings, plants and equipment of the panel plant and sawmill in Brazil, which lowered the value of these assets to ThU.S.$59,966. The lowest value was recorded in the U.S. GAAP
results for the year 2008 as an impairment loss of assets.

NOTE 4. CASH FLOW STATEMENT (IAS 7)

Cash and cash equivalents includes cash flow, bank account balances, fixed term deposits, repurchase agreements and mutual funds. They are
short-term investments that are readily convertible into cash, and are subject to an immaterial change in value.

The
objective of fixed term deposits is to maximize earnings on short-term cash flow surpluses. This instrument is authorized by Araucos Investment Policy, which establishes a mandate that allows investments in fixed income securities. In general,
these instruments have a maturity period of less than ninety days.

Arauco invests in local mutual funds to maximize the
profitability of cash flow surpluses in Chilean Pesos, or in international mutual funds in foreign currencies such as U.S. Dollars or Euros. These instruments are acceptable under Araucos Investment Policy.

As of the date of these consolidated financial statements, there are no significant amounts of cash or cash equivalents that are freely
available.

Deferred Tax Liability

Deferred tax liability corresponds to income tax amounts payable in future periods related to taxable temporary differences.

Currently, Arauco has not recognized deferred taxes associated with temporary differences arising from investments in subsidiaries,
because the Company controls the date on which the temporary differences will be reversed and/or it is not likely that those differences will change in the foreseeable future.

The following table details deferred tax liabilities:

Description of Property, Plant and Equipment Pledged as Guarantee

Regarding Forestal Río Grande S.A, an affiliate of Fondo de Inversión Bío Bío, a special purpose entity, we
note that in October 2006, first and second mortgages were executed in favor of JPMorgan Chase Bank N.A. and Arauco, respectively, which prohibited the sale of any property currently belonging to the aforementioned special purpose entity, in order
to ensure fulfillment of payments to Fondo de Inversión Bío Bío.

In September 2007, Forestal Río
Grande S.A acquired real estate in Yungay, located in Chiles Region VIII, for which the company executed a first mortgage with prohibition to sell and encumber in favor of, among others, JPMorgan. Similarly, a second mortgage with prohibition
to sell and encumber was executed in favor of Arauco.

NOTE 9. ORDINARY REVENUE RECOGNITION (IAS 18)

(a) Policy on Revenue recognition from to the Sale of Goods

Revenue from the sale of goods is recognized when an Arauco entity has transferred to the buyer the significant risks and rewards of
ownership, when the amount of revenue can be reliably measured, when Arauco cannot influence the management of the sold goods and when it is probable that the economic benefits associated with the transaction will flow to the entity.

Sales are recognized in terms of the arranged price stated within the sales contract, net of volume discounts and estimated refunds at
the date of the sale. Volume discounts are evaluated in terms of estimated annual purchases. There is no significant financing component given that receivables for sales are collected within a low average time period, which is in line with market
practices.

(b) Policy on Revenue recognition from to Rendering of Services

Arauco has leases and pest control services whose incomes are derived from fixed price service contracts, generally recognized during the
period of the service contract on a straight-line basis throughout the duration of the contract.

NOTE 10. EMPLOYEE BENEFITS (IAS 19)

Disclosure of Termination Benefits

This refers to severance payment obligations for years of service due to termination of service contracts that arise from benefits stated
within work contracts and/or as severance payments stated in the Labor Law. According to IFRS these are considered post-employment benefits.

Description of Recognized Termination Benefits

This is an estimate of the years of service-based severance payments to be recognized as a future termination payment liability, according
to in force work contracts held with workers and pursuant to actuarial valuation criteria for this type of liability.

The
main factors considered for calculating the actuarial value of severance payments for years of service are employee turnover, salary increases and life expectancy of the workers included in this benefit.

NOTE 11. EFFECT OF FOREIGN CURRENCY EXCHANGE RATE VARIATIONS (IAS 21)

The functional currency of Brazilian subsidiaries and associate companies is the Brazilian Real. Therefore, their
individual financial statements have been expressed in the presentation currency as follows:



|(i) | Assets and liabilities for each balance sheet are translated at the closing exchange rate;
|--- | ------------------------------------------------------------------------------------------



|(ii) | Incomes and expenses for each income statement are translated at the average monthly exchange rate, given that to date this average has been a fair estimate of the
cumulative effect of the exchange rates at the time of the transactions;
|---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(iii) | All the resulting exchange differences are recognized as a separate component of net equity.
|----- | --------------------------------------------------------------------------------------------

In consolidation, the exchange rate differences arising from the translation of a net investment in companies that use currencies other
than the U.S. Dollar, and those from loans and other instruments in foreign currencies recognized as hedging these investments, are assigned to net equity.

NOTE 14. CONSOLIDATED AND SEPARATE FINANCIAL STATEMENTS (IAS 27)

Subsidiaries are all entities over which Arauco has the power to manage financial and operational policies. This
generally means holding more than one half of the voting rights of such entities. Stock held in an entity and the effect of the potential voting rights that are currently being exercised or converted are considered when evaluating whether the
Company controls another entity. Subsidiaries are consolidated as of the date on which control is transferred to the Company, and are excluded when control is terminated.

Arauco applies the purchase method to recorded a business combination. Acquisition cost is the fair value of assets delivered, of equity
instruments issued and of the liabilities incurred or committed at the date of exchange, plus all direct costs attributable to the acquisition. Identifiable acquired assets and liabilities as well as the contingencies committed to in business
combinations are initially recognized at fair value at the date of acquisition, despite minority interest scope. Excess of acquisition cost over the Fair Value off the Companys share of the identifiable net assets acquired is recorded as
goodwill. If this is less than Fair Value of the net assets of the subsidiary acquired, the difference is recognized directly in the statement of income.

All intercompany transactions, accounts receivable, accounts payable and intercompany unrealized profits are eliminated.

Disclosure of Subsidiary Investments

On 26 August, 2009, Placas do Paraná S.A., Araucos Brazilian subsidiary, acquired 100% shares of the company Tafisa
Brasil SA (now Arauco do Brasil S.A.) through a purchase agreement signed with SCS Beheer, B.V. and Tafiber-Tableros de Fibras Ibéricos, S.L., subsidiaries of Sonae Indústria, SGPS, S.A. Placas do Paraná S.A. paid ThU.S.$166,977
for Tafisa Brasil S.A. shares. This investment is recognized at provisional fair value, which is currently under review. As of December 31, 2009, goodwill was estimated to be ThU.S.$56,657. The acquisition of this partnership will allow
Arauco to strengthen its presence in the Brazilian market for fiberboards, where it is already involved through Placas do Paraná S.A.

On June 30, 2009, Arauco through its subsidiary Arauco Internacional S.A., acquired 80% of Savitar (Forestal Talavera S.A.) for
ThU.S.$10,131. Previously, on March 28, 2008, through its subsidiary Faplac S.A., Arauco Internacional S.A. acquired 20% of Savitar. This acquisition generated a profit of ThU.S.$701 presented in the Comprehensive Income Statement under
Negative goodwill and was immediately recognized.

NOTE 16. INTERESTS IN JOINT VENTURES (IAS 31)

These investments are presented in the Consolidated Balance Sheet together with investments in associates in the Investment in associates
line. They are presentedusing the equity method.

If a Joint Venture associate incurs negative equity as a result of legal or
implicit obligations of its associate, or has made payments on behalf of its associate, then it must recognize a liability by reducing the value of the investment to zero until the associate generates profits that would reverse the negative equity
previously generated due to the losses.

a) Stora Enso Amsterdam B.V.-Forestal Cono Sur S.A. joint venture

On September 27, 2009 Stora Enso Amsterdam B.V. (a subsidiary of the transnational Swedish-Finnish company Stora Enso Oyj) agreed to
provide 100% of the shares of Stora Enso Uruguay S.A, to Forestal Cono Sur S.A., a subsidiary of Arauco in Uruguay at that date and Arauco to provide 50% of the shares of Forestal Cono Sur S.A.to Stora Enso Amsterdam B.V., resulting in a change of
control of this subsidiary. Hence, Arauco has a 50% of participation in Forestal Cono Sur S.A. For accounting purposes, Arauco elected to early adopt IAS 27R Consolidated and Separate Financial Statements and recorded a profit as a
result of the incorporation of the joint venture of ThU.S.$ 28,167, which is presented in the Financial Income Statement in the line Other Profit (loss).

The main assets acquired from Ence are: 130,000
hectares of land (of which 73,000 hectares are forestry plantations and 6,000 hectares are under agreements with third parties); one industrial site, the necessary environmental permits for the construction of a pulp mill; a river terminal; one chip
producing mill, and one nursery.

All these assets are added to the land and plantations that Stora Enso and Arauco control
through a joint venture in Uruguay, which currently maintains a forestry equity of approximately 250,000 hectares of land, of which 125,677 hectares are planted.

At a later date as mentioned in paragraphs a) and b), Arauco made contribution to Forestal Cono Sur S.A. and Ence Group that amounted to
ThU.S.$2,000 and ThU.S.$10,000, respectively.

The investments in Uruguay mentioned above qualify as joint ventures by the
existence of contracts stipulating that both Arauco and Stora Enso maintain joint control of such investments.

Furthermore,
Arauco holds a 50% share in Eka Chile S.A.(Eka), a company that sells sodium chlorate to cellulose plants in Chile. A contractual agreement in effect between and Arauco and this company has permitted Arauco and Eka to initiate certain
joint venture activities.

NOTE 17. DISTRIBUTABLE NET PROFIT AND EARNINGS PER SHARE

Distributable net profit

As a general policy, the Board of Directors of Arauco agreed that the net profit to be distributed as dividend payment is determined based on the
effective realized profit, net of any relevant variations in the value of unrealized assets and liabilities, which are excluded from the calculation of net profit during the period such changes are made.

As a result of the foregoing, for purposes of determining the distributable net profit of the Company, which is the net profit to be considered for
calculating the minimum required and additional dividend, the following unrealized results are excluded from the results of the exercise:



|1) | Those relating to the fair value recorded for forestry assets covered by IAS 41, restoring them to the net profit at the time of its completion. For these purposes,
this includes the realized portion of such increases in fair value for assets sold or disposed by other means.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2) | Those generated through the acquisition of entities. These results will be restored to the net profit at the time of their realization. For this purpose, the results
are realized when acquired entities generate a profit after their acquisition or when such entities are sold.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The deferred taxes associated with the amounts described in points 1) and 2) are also excluded.

The following table details adjustments made for the determination of distributable net profits for the year ended December 31,
2009:



|                                                    |  |                         |

|Distributable Net Profit at 12/31/2009              |  | 206,789                 |  

As
a general matter, the Company expects to maintain its policy on dividends, for all future tax periods, around 40% of net profits to be distributed for each tax year, but will also consider the alternative of distributing a provisional dividend at
year end.

Other current liabilities included in the Consolidated Balance Sheet dated December 31, 2009 shows
ThU.S.$56,778 for the provision of minimum dividend. This balance represents 40% of distributable net profit less the interim dividend of ThU.S.$25,957 paid on December 16, 2009 based on net profits in this period.

The consolidated financial statements dated at December 31, 2008 were approved at
the 30th Shareholders Meeting, held on April 23, 2009 and were prepared in accordance with Chilean GAAP, which are issued by the Accountants Association of Chile in accordance with the standards issued by the Chilean Securities Commission and
do not compare with the balances for financial year 2008 included in these consolidated financial statements, because such balances have been restated according to the IFRS. Note 2 details the reconciliation of equity and the income statement.

Earnings per share

The earnings per share are calculated by dividing the profit attributable to shareholders of the Company with the weighted average of
outstanding common shares. Arauco has no dilutive shares.

NOTE 18. IMPAIRMENT OF ASSETS (IAS 36)

The recoverable amount of Property plant and equipment is measured whenever there is an indication that the asset may have suffered
deterioration of its value. Among the factors to consider as evidence of impairment are the diminution in market value of assets, significant changes in the technological environment, obsolescence or physical impairment of assets and changes in the
way the asset is used or expected to be used (which could involve its disuse). Arauco evaluates at the end of each reporting period whether there is any evidence of the factors mentioned.

For this evaluation, assets are grouped into the smallest group of assets that generates cash inflows independently.

At the end of 2009, there were signs of deterioration as follows:

The decrease in demand for sawn timber products due primarily to the credit crisis and the continued downturn in the real estate market
in the United States has led Arauco to decide to permanently close the following sawmills: La Araucana, Escuadrón, Lomas Coloradas, Coronel y Coelemu. Arauco has temporarily closed Horcones II and the remanufacturing plant Lomas Coloradas.
All closed facilities are located in Chile.

The recoverable value of the permanently closed facilities was determined based
on sales estimates and residual value. These estimates were made by both external and internal evaluators.

In the case of the
mill and remanufacturing plant that temporarily closed, our assessment of the deterioration indicated that the book value did not exceed the recoverable amount. This assessment was made using projections about factors such as volumes, sales prices
and production costs. The discount rate of discounted cashflow used by Arauco to evaluate its projects in Chile is 8%.

The
amount provisioned in net results for impairment is ThU.S.$3,110 at December 31, 2009 (ThU.S.$5,412 at December 31, 2008). ThU.S.$4,113 relates to an increase in value of such provision due to the closure of Coronel and Coelemu sawmills
and the increase in the obsolescence provision of machinery and equipment, less ThU.S.$1,003 due to a reduction of the provision for assets allocated to the closure of mills that, given current market conditions, are expected to have a recoverable
value.

Goodwill

Goodwill is allocated to groups of cash generating units identified according to the operating segments to which the goodwill is
attributable. The goodwill generated by the investment in Arauco do Brazil (formerly Tafisa) was assigned to the panel segment Pien plant. The recoverable amount of the cash-generating unit was determined based on calculations of its value in use
and for this calculation we used projected cash flows based on the operational plan approved by the management covering a period of 10 years, applying a discount rate of 10%, which does not exceed the long-term average growth rate for the panel
segment in Brazil. At December 31, 2009 this goodwill amounted to ThU.S.$60,642.

NOTE 19. PROVISIONS, CONTINGENT ASSETS AND CONTINGENT LIABILITIES (IAS
37)

Lawsuits or other Legal Proceedings

Below are details of the lawsuits in which Arauco is involved that have been deemed relevant to report:

1. (i) On October 8, 2007, the Administración Federal de Ingresos Públicos (Federal Administration of Public
Income) (AFIP) initiated an ex oficio procedure against the Companys Argentine affiliate Alto Paraná S.A. (APSA) questioning whether APSA erred in deducting from its income tax liability certain expenses,
interest payments and exchange rate differences generated by Private Negotiable Obligations which were issued by APSA on 2001 and paid in 2007.

On November 20, 2007, APSA submitted a counterclaim to the claims presented by AFIP, completely rejecting all AFIPs
allegations and asserting legal arguments that justify its actions in the determination of its tax burden.

On
December 14, 2007, AFIP notified APSA that its counterclaim had been dismissed, thus issuing an ex-oficio ruling and ordering the payment, within 15 working days, of the calculated income tax difference for the 2002, 2003 and 2004 fiscal years,
which includes the principal amount owed, interest and fines.

On February 11, 2008, APSA appealed the aforementioned
ruling before the Tribunal Fiscal de la Nación (National Tax Court) (TFN).

On February 8, 2010, APSA
was notified of TFNs ruling, which confirmed the ruling issued by AFIP, with court expenses, based on arguments different from those that justified AFIPs ex-oficio decision. This decision by the TFN extinguished the administrative
process.As a result, our only remaining option was to pursue a remedy before the Cámara de Apelaciones en lo Contencioso Administrativo Federal (Contentious Administrative Matters Federal Appeals Court) (CACAF) and, subsequently,
the Corte Suprema de Justicia de la Nación (National Supreme Court of Justice).

On February 15, 2010, APSA
appealed before the CACAF, making all necessary submissions with the purpose of attaining a revocation of the contested decision. APSA paid litigation fees (tasa de justicia) in the amount of $5,886,053 Argentine Pesos in connection with these
proceedings.

On March 18, 2010, the CACAF, issued a court decree in which it ordered the AFIP to refrain from requesting
the blocking of preventive interim relief measures, administratively demanding payment, issuing debt invoices, or initiating judicial collection actions, including seizure of property and other enforcement measures, against APSA until CACAF reaches
a decision on APSAs request for precautionary measures.

On May 13, 2010, following the posting of a guarantee by
APSA, the First Chamber (Sala 1) of the Contentious Administrative Matters Federal Appeal Court granted the preliminary injunction requested by APSA, suspending the execution of AFIPs resolution until a final decision could be reached in the
case.

In spite of the TFNs ruling, the opinion issued by APSAs external counsel
continued to be that APSA has proceeded in a lawful manner in deducting the amount questioned by the State. External counsel maintains that there is a good chance that the TFNs ruling will be overruled and that the AFIPs ex-oficio
decision will be rendered without effect. Due to the above, no provisions have been recognized for the periods in which the Negotiable Obligations were in force.

(ii) Within the course of this cases proceedings, and particularly regarding payment of the litigation fees (tasa de
justicia) before the TFN, on July 18, 2008, the Examining Officer ordered APSA to pay $10,447,705 Argentine Pesos as payment of Tasa de Actuación(Litigation Fee) before the TFN. On August 14 2008, APSA filed a petition
with the court requesting that this order be reconsidered, or in the alternative, rejected on the grounds that the requested amount was unreasonable. APSA provided evidence that it had paid $1,634,914 Argentine Pesos, considering that this was the
actual amount due, pursuant to Law, for the Tasa de Actuación(Litigation Fee). On April 13, 2010, the Sala I (First Courtroom) of the CACAF denied APSAs appeal. On April 26, APSA filed an ordinary appeal against the
latter decree before the Supreme Court of the Justice, the resolution of which is still pending. In order to avoid having the appeal denied by the Appeals Court or it being declared inadmissible by the Supreme Court of Justice, and to properly
defend APSAs rights, an extraordinary appeal was filed on May 6, 2010. Based on their analysis of the grounds underlying the appeal, APSAs counsel has an optimistic view of the case.

2. With regard to the Valdivia Mill, owned by Arauco, various criminal proceedings have been filed at the corresponding Tribunal de
Garantía (Warranty Court), relating to environmental violations that were allegedly committed as a result of operations at the mill. All criminal proceedings have been addressed through a single investigation. The complaints relate to Article
291 of the Código Penal (Penal Code), Article 136 of the Ley de Pesca (Fishing Law) and Article 38 of the Ley de Monumentos Nacionales (National Monuments Law).

In the Companys opinion, the evidence submitted in the investigation does not prove the existence of any offense or the
responsibility off the Company or of any of its employees for the alleged events.

3. With regard to the Valdivia Mill, on
April 27, 2005, the Consejo de Defensa del Estado (National Defense Council) filed a civil lawsuit against the Company for reparation of environmental harm and indemnification before the Primer Juzgado Civil de Valdivia (First Civil Court of
Valdivia) (Rol 746-2005).

The Company filed its response, arguing that it is not responsible for the environmental damages
and therefore that the indemnification payments as well as the alleged reparation, are inadmissible. The lawsuit is currently in progress.

4. With regard to the Nueva Aldea Mill, on December 20, 2007, the Company was notified of nine similar complaints. Eight complaints
are directed against Echeverría Izquierdo Montajes Industriales S.A., as employer, and against Arauco, as subsidiarily responsible, and also against the Company directly. The other complaint is directed against Mr. Leonel Enrique
Espinoza Canales, as employer, against Arauco, as subsidiarily responsible, and also against Arauco directly.

The complaints
request that all plaintiffs (72 plaintiffs in total) be indemnified for the damages that they allegedly suffered as a result of an accident in which three persons working for the contractor Echeverría Izquierdo Montajes Industriales S.A. were
allegedly involved. This contractor was undertaking construction work at the Nueva Aldea Pulp Mill in December 2005. After being notified of these complaints, the Company opposed them on the

basis of lack of jurisdiction, and, answered the principal complaints, arguing that they are invalid for failure to state a claim. The Company also responded to the secondary complaints made
directly against the Company, requesting that they be rejected for lacking any merit. All these demands have been consolidated into a single action, for which a trial is currently underway.

Based on these same events, on January 29, 2008, the Company was notified of an action for damages due to a work accident filed by
Mr. Fernando Vargas Llanos, against his former employer Inspección Técnica y Control de Calidad Limitada (ITC), the construction company Echeverría Izquierdo Montajes Industriales S.A. and against the Company. The complaint
requests that Mr. Vargas be indemnified for the damages that he allegedly suffered as a result of the events that took place in December 2005.

Notified of said complaint, the Company opposed it on the basis of lack of jurisdiction, and, answered the principal complaint stating
that it should be dismissed for lacking any merit. On July 20, 2009 the Court ordered the dismissal of the procedure, since the plaintiff had ceased in his procedural activity for more than six months. This order is currently being contested by
the plaintiff and is pending a final decision.

Finally, based on these same events, on November 10, 2009 the Company was
notified of a labor complaint, on a general application procedure, claimed by 14 ex-employees of Echeverría Izquierdo Montajes Industriales S.A. construction company, against the latter as a principal complaint, and against Arauco as
subsidiarily responsible, based on emotional distress suffered due to alleged exposure to a radioactive isotope during the accident that occurred in Planta Nueva Aldea on December 14 and 15, 2005. The date of the corresponding hearing is
pending.

Considering that the position of the Company is supported by solid legal arguments, there is a reasonable likelihood
of a favorable outcome for the Company.

5. With regard to the Constitución Mill, on January 24, 2006, the Company
was notified of a interdicto posesorio (civil claim) brought by Mrs. Alvaro Santa María Prieto and Alejandro Lagos Letelier before the Juzgado de Letras de Constitución (Constitucional Court), seeking an order outlining the
necessary measures in order that the air surrounding the Constitución Mill would not be harmful. This demand has not progressed in more than two years and has now been filed.

In the Companys opinion and based on information available to us, this complaint lacks merit.

6. With regard to the Lincancel Mill, pursuant to Resolution No. 1828 dated June 13, 2007, the Superintendencia de Servicios
Sanitarios (Sanitary Services Superintendency) (SIS) initiated an administrative sanctioning process against the Company regarding the Companys alleged surpassing of the maximum levels allowed for the pH parameters and suspended
solids. The Company presented its responses within the time established in the resolution, which was June 25, 2007.

Pursuant to a resolution dated June 26, 2007 the SIS resolved to broaden the charges included in Resolution 1828.

The Company submitted its response dated as of July 17, 2007. However, by Resolution No. 2589 of August 28, 2007, the SIS
sanctioned the Company with a fine of 100 UTA for not complying with the applicable emission norms (a fine that has already been paid by the Company) and with a fine of 1,000 UTA for having put in danger, as is indicated in the resolution, the
health of the population. The latter sanction was appealed in the Santiago Court system and the matter is currently in progress.

7. On August 14, 2009, the Company was notified of a demand for compensation for
damages filed by lawyers representing a group of 168 fishermen from Region VII and workers in related activities, located in the creeks of artisanal fishermen of Putu, La Trinchera, Iloca, Duao and Llico.

This demand seeks an order requiring payment by the Company for alleged damages caused in the Mataquito River, its estuary and the
adjacent coastline as a result of the alleged environmental damage, and requests that the Company be ordered to pay each plaintiff.

On May 25, 2010, the Court decided to accept the Companys objection based on the ground of incompetence of the plaintiff. The
plaintiff did not appeal this decision, and therefore, the case has been terminated.

8. The parents and brothers of
Mr. Julio Gonzalo Cartes Barrientos, a worker who was electrocuted while trying to repair a luminaire, filed on August 3, 2004 a civil suit for compensation for tort damages against the Company, as contractor, and against José
Reinaldo Vargas as a Company principal.

The Company claimed that the claim had lapsed and argued that the worker, who
disregarded the instructions of his superiors by not assembling scaffolding to repair the luminaire, was negligent. The decision of first instance was favorable to the Company, accepting that the claim had lapsed. But, the decision was quashed ex
officio, remitting the case back to the first instance. The new first instance decision found both defendants jointly and severally liable. The defendants filed an appeal and its resolution is still pending.

9. On August 25, 2005, the Chilean Servicio de Impuestos Internos (the Chilean IRS) issued tax calculations No. 184
and No. 185 of 2005 objecting to certain capital reduction transactions effected by Arauco on April 16, 2001 and October 31, 2001, and furthermore, requested reimbursement from the Company for amounts returned to it in respect of
certain claimed tax losses. On November 7, 2005, the Company requested a Review of the Supervision Action (Revisión de la Actuación Fiscalizadora, or RAF), which is an administrative review of the tax action brought by
the Chilean IRS, and subsidiarily, a claim was filed against the abovementioned tax calculations No. 184 and 185 of 2005. The RAF was resolved on January 9, 2009 by the Chilean IRS, which resolution, however, only partially sustained the
Companys request. In response, the Company filed an additional complaint with regard to the portion of the RAF that was not granted by the administrative review. As of the date of this annual report, the investigation in respect of this
complaint is pending.

Considering that the position of the Company is supported by solid legal arguments, there is a
reasonable likelihood of a favorable outcome for the Company. However, if this result does not occur, the Company may be subject to an obligation for the amount of taxes that it allegedly failed to pay, plus any accrued interest as of the payment
date.

10. On April 14, 2009, Forestal Celco S.A. was notified of a civil lawsuit filed by Mario Felipe Rojas
Sepúlveda on behalf of Víctor Adrián Gavilán Villarroel against Cooperativa Eléctrica de Chillán Limitada and against Forestal Celco S.A. The lawsuit aims to make both companies jointly and severally liable
for compensation of alleged material damages suffered as a result of a fire that occurred on January 12, 2007 on the El Tablón county property, which belongs to Forestal Celco S.A.

On April 30, 2009 Forestal Celco S.A. filed objections pointing to defects in the
demand. The plaintiff rectified the defects, and the Company replied to the demand. As of this date, following all mandatory proceedings, the ordinary probationary period has concluded, and the parties are currently waiting for an expert witness
report on causes of the fire.

11. On December 1, 2007, Forestal Celco S.A. was notified of a civil lawsuit filed by
Marcela Larraín Novoa on behalf of Nimia del Carmen Alvarez Delgado against Patricia del Carmen Muñoz Zamorano and Forestal Celco S.A. This lawsuit seeks to reclaim an 88% share of the rights to the Loma Angosta property,
which has a surface area of 281.89 hectares. This property was purchased by Forestal Celco S.A. from Patricia del Carmen Muñoz Zamorano in 1994. To date, Patricia del Carmen Muñoz Zamorano has not yet been notified of this action.

As a result on May 18, 2008, the Company filed a motion to correct the claim, which was allowed and accepted by the
Court. As of this date, the plaintiff has not corrected the defects of its claim.

12. On April 29, 2004, Aserraderos
Arauco S.A., an Arauco subsidiary, was notified of a lawsuit for contract fulfillment and compensatory damages, filed before the Second Civil Court of Concepción by Ingeniería y Construcciones Ralco Ltda, case No. 3.218-2008. The
plaintiff maintains that the contracts entered into with sawmill administrators include Aserraderos Arauco S.A. The court order dictated a ruling that established the facts to be proved by the parties. However, there have been no further
developments for over a year.

13. On January 29, 2009, Forestal Valdivia S.A. was notified of a civil lawsuit filed by
Carlos Nambrard Figueroa by himself and on behalf of the members of the Julia Figueroa Olivero Estate, against Forestal Valdivia S.A and Forestal Tornagaleones S.A., which aims to make both companies jointly and severally liable for compensation of
alleged material and moral damages suffered as a result of the occupancy, plantation and operation of an agricultural piece of land (Cerros del Lingue) over which the estate alleges ownership rights. Forestal Validivia S.A. has held ownership rights
and material and legal possession for more than ten years with respect to such piece of land.

As a result, the company
responded to the lawsuit arguing that it should be rejected for a lack of legal basis. Furthemore as a result of the plaintiffs failure to prosecute the action, Forestal Valdivia S.A. requested that the proceedings be declared abandoned. The
Court decided to accept the unopposed Forestal Valdivia petition, and ordered the case abandoned.

14. On November 17,
2003, Bosques Arauco S.A., an affiliate of the Company, was notified of a property restitution claim brought by Ms. Celmira Maria Curin Tromo, whom requested the restitution of certain real estate, its profits and damages in a Special
Indigenous Lawsuit, claming that she is the sole and exclusive owner of the 5.5 hectares of land, which has allegedly been exploited by Bosques Arauco S.A., in blatant disregard of her property interest. On June 6, 2008, the first instance
decision was issued, denying the claim. The decision was appealed and the Ilustrísima Corte de Apelaciones de Temuco (High Court of Appeals of Temuco) overturned the decision on January 6, 2009, finding in favor of the plaintiff with
regard to every portion of the claim and ordering the restitution of the land, along with all profits and damages caused by Bosques Arauco S.A. to the land, the assessment of which was deferred to the decisions execution phase.

On October 28, 2009, the plaintiff requested the execution of the ruling with notice to the defendant. Aside from the restitution of
the property and its products, the plaintiff also requested damages for the pain and suffering she had allegedly personally endured. After being notified of the request, Bosques Arauco S.A., in turn, requested that this request be nullified on the
ground that the alleged pain and suffering was not an issue in the judicial proceedings and, hence, that the ruling should not include any such damages.

The Court then ordered the suspension of proceedings, while the ruling on the incidental
plea of nullity is pending.

15. On April 17, 2010, a worker of the Companys contractor, Obras Industriales Salfa
S.A., filed a complaint against his employer (Salfa) and also jointly and/or jointly and severally, against the Company. This complaint claims damages for loss of profits and pain and suffering caused by a labor accident (inhalation of sulfhydric
acid). Plaintiff claims $104.573.808 (Chilean pesos) for damages for loss of profits and $700.000.000 (Chilean pesos) for moral damages. There have been no significant developments in this action as of this date.

16.- On November 28, 2008, APSA was notified of Resolution 212 issued by the Argentine Central Bank (BCRA) on November 19,
2008, by which the BCRA ordered Indictment No. 3991 questioning the timely liquidation of certain foreign currency with respect to APSAs export proceeds. APSA responded to the charges in a timely and correct manner.

As of the date of these consolidated financial statements and considering the preliminary state of proceedings, APSA legal advisors are
not in a position to estimate the outcome. Therefore, with the understanding that there are no legal grounds for the charges, no provision has been made for this claim.

17.- As a consequence of the merger of APSA and Faplac S.A., APSA, as of January 1, 2010, assumed the contingency derived from
litigation between Faplac S.A. and Gas del Estado S.A. regarding the breach of the gas supply contract entered into by Resinfor Metanol S.A., a company which was Faplac S.A.s legal predecessor.

On August 27, 1985, Resinfor Metanol S.A. filed a suit against Gas del Estado S.A. Gas del Estado answered the complaint requesting
the lawsuits total dismissal. Gas del Estado also filed a counterclaim against Resinfor Metanol S.A., requesting the termination of the agreement entered into on August 27, 1985. The counterclaim also requested the full performance of the
contract as it was agreed upon by the parties, especially with regard to the maximum and minimum assured volume of flow and the penalty established in the event of breach of contract in Clause Seven, as well as the appropriate fine as a consequence
of the suspension of the application of article 4 of Ruling MOSP 391/85 (as provided by Law 23,697, Decree 1930/90 and other concurrent regulation).

On March 17, 2008, the Juzgado Nacional de Primera Instancia en lo Contencioso Administrativo Federal (Federal Contentious
Administrative National Court of First Instance No 1) issued a ruling, declaring the following:



|- | Resinfor Metanol S.A. was deemed to have abandoned its claim and its right, and was required to pay court costs.
|- | ----------------------------------------------------------------------------------------------------------------



|- | Resinfor Metanol S.A. was ordered to reimburse the defendant Gas del Estadofor payments made after
December 15th, 1992, as a consequence of the
injunctive relief granted and until said relief was revoked on December 1994, as well as interest, in accordance with the rate received by Banco de la Nación Argentina for its 30-day common discount operations.
|- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

On February 24, 2009, the Cámara Nacional de Apelaciones en lo Contencioso Administrativo Federal (Federal Contentious
Administrative National Chamber of Appeals) (Third Chamber) issued a ruling which partially dismissed the appeal filed by Faplac S.A., and confirmed both

the reimbursement to the plaintiff of payments carried out after December 15, 1992 and the court costs as defined before the First Instance Court. However, the Third Chamber did declare the
ruling which ordered the payment of interest on the amounts reimbursed as null and void, thus rendering ineffective the Court of First Instances decision on this particular issue.

Faplac S.A., Resinfor Metanol S.A.s successor, filed an Ordinary Remedy before the Corte Suprema de Justicia de la Nación
(Supreme Court of Justice)(CSJN), which was granted. In turn, Gas del Estado filed an extraordinary remedy before the CSJN. The CSJN has not yet ruled on the applicability of this remedy. Once Gas del Estados remedy has been ruled on, CSJN
will issue a ruling regarding the Ordinary Remedy filed by Faplac S.A.

At the closing date there are no other contingencies
that might significantly affect the Companys financial, economic or operational conditions.

NOTE 20. TYPES OF INTANGIBLE ASSETS (IAS 38)

Arauco holds the following main intangible assets:

Purchased goodwill

Computer software

Water-rights

Recognition and
Measurement criteria of Identifiable Intangible Assets

Cost Model

After initial recognition, intangible assets are carried at cost, including any accumulated amortization and impairment losses.

Amortization Method for Computer Software

Amortization of an intangible asset with a finite useful life shall be carried on a systematic basis over the asets useful life.
Amortization begins when the asset is available for use, which is when it complies with all the necessary conditions to operate in the manner foreseen by the Company.

Other Identifiable Intangible Assets

Acquired goodwill is assigned to each of the cash-generating units (CGU) in order to periodically test for impairment losses.
Assignment is carried out in the CGUs that are expected to benefit from the business combination in which the goodwill arose.

NOTE 21. BIOLOGICAL ASSETS (IAS 41)

Araucos biological assets include its forestry plantations of mainly radiata and taeda pine. The total plantation is distributed in
Chile, Argentina, and Brazil, reaching 1.5 million hectares, of which 931 thousand hectares are existing plantations, 324 thousand hectares are native forest, 184 thousand hectares are used for other purposes and 45 thousand
hectares are used for planting.

At December 31, 2009 the production volume totaled 26.1 million cubic meters (28.8
million cubic meters at December 31, 2008).

The main considerations in determining the fair value of biological assets
include the following:

- Arauco uses the discounted future cash flows of its forest plantations, which are based on a harvest
projection date for all existing plantations. Arauco does not consider future plantations.

- Current equity is projected
assuming that total volume does not decrease and a minimum demand equal to the current level is sustained.

- The harvest of
forest plantations supplies raw material for all other products that Arauco produces and sells. By directly controlling the development of forests that will be processed, Arauco is assured of having high quality timber for each of its products.

- Cash flows are determined in terms of harvest and expected sale of forestry products, associated with the demand from the
Companys owned industrial centers and sales to third parties. Sales margin is also considered in the valuation of the different products that are harvested in the forest. Any changes in the value of the plantations, in accordance with the
criteria previously described, are accounted for in the current financial years income statement, pursuant to IAS 41. These changes are presented in the Consolidated Statement of Income under Other operating income, and at December 31,
2009 amounted to ThU.S.$155,532 (ThU.S.$65,201 at December 31, 2008). Additionally, cost of sales include a higher cost of ThU.S.$115,969 (ThU.S.$172,710 at December 31, 2008) resulting from the difference between the cost of wood at fair
value versus cost basis.

- Forests are harvested according to the needs of Araucos production plants.

- The discount rates used are: in Chile 8%, in Argentina 12% and in Brazil 10%.

- It is assumed that prices of harvested timber are constant in real terms based on market prices.

- Cost expectations with respect to the lifetime of the forests are constant based on estimated costs included in the projections made by
Arauco.

- The average crop age by species and country is:

|                       |  | -10  |  | (390,006 | )

Forestry
plantations classified as current assets correspond to those to be harvested and sold within the next year.

The Company holds
fire insurance policies for its forestry plantations, which together with company resources and efficient protection measures for these forestry assets allow financial and operational risks to be minimized.

Uruguay

Arauco owns
biological assets in Uruguay through a joint venture in partnership with Stora Enso, which are presented in these consolidated financial statements under the equity method (see Note 16).

At December 31, 2009, Araucos investment in Uruguay represented a total of 126,786 hectares, of which 62,838 hectares are
allocated to plantations, 2,870 hectares to native forest, 42,625 hectares for other uses and 18,453 hectares for planting.

Detail of
Biological Assets Pledged as Security

There are no forestry plantations pledged as security, except for those belonging to
Forestal Río Grande S.A. (affiliate of Fondo de Inversiones Bio Bio, a special purpose entity). In October 2006, pledges without transfer and agreements not to sell and encumber were made in favor of JPMorgan and Arauco, for forests located
on their own land. At December 31, 2009, the fair value of these forests reached ThU.S.$59,819 as compared to ThU.S.$81,083 at December 31, 2008.

Detail of Biological Assets with Restricted Ownership

As of the date of these consolidated financial statements, there are no biological assets with restricted ownership.

Disclosure of Agricultural Products

Agricultural Products relate mainly to forestry products that are intended for sale pertaining to the operation and are valued at fair
value at the closing period.

No significant grants have been received.

NOTE 22. ENVIRONMENT

Environment Management

For Arauco, sustainability means management strategy. This strategy incorporates values, commitments and standards, that together with the
adoption of best practices as well as the use of the latest available technologies, seek to continuously improve the Companys environmental management. It is the environmental department and each of its specialists that ensures these
guidelines are met and are put in to practice in everyday company operations.

All of Araucos production units have
certified environmental management systems, which reinforce the Companys commitment to environmental performance and ensure the traceability of all raw materials used.

Arauco uses several supplies in its productive processes such as wood, chemical products, and water, etc., which in turn produce liquid
and gas emissions. As a way to make the companys environmental management more efficient, significant progress has been made to reduce consumption and emissions.

Environmental investments have been made related to the control of atmospheric emissions, process improvements, water and waste
management, as well as effluent treatment, in order to improve the environmental performance of all of Araucos business units.

Fair Value Financial Assets with Changes in
Profit and Loss

Fair value financial assets with changes in profit and loss are trading securities. Financial assets
classified in this category are mainly acquired for sale in the short term. Derivatives are also classified as trading securities unless they are defined as hedging instruments. Assets in this category are classified as current assets and are
recorded at fair value, recognizing changes in value in the income statement. These assets are held with the objective of maintaining adequate liquidity levels to meet the Companys obligations.

The following table details Araucos financial assets at fair value with changes in
profit and loss:

Swaps:
At the closing balance sheet date, financial assets classified in this category are not considered hedging instruments, as there is no uncertainty as to their underlying liability, so these instruments comply with the management strategy regarding
implicit structural liquidity risk for Arauco operations. The fair value of this item decreased by 25% compared to December 31, 2008 due to lower horizon cash flows from swaps.

Forwards: Arauco acquires this type of instrument to hedge functional currency exchange rate risks. These instruments are
generally acquired with short-term maturity periods. The fair value of this item has decreased by 54% because the Company has entered into fewer derivative contracts in 2009 as compared to 2008.

Mutual Funds: Arauco invests in local mutual funds to maximize the profitability of cash flow surpluses in Chilean Pesos, or in
international mutual funds in foreign currencies such as U.S. Dollars or Euros. These instruments are permitted under the Companys Invetment Policy. As of the date of these consolidated financial statements, the Company has increased its
position in this type of instrument by 277% as compared with December 2008.

Loans and Receivables

These are non-derivative financial assets with fixed or determinable payments. These instruments are not available for trading on any
active trading market or otherwise. In the balance sheet they are included in Current Assets, except for assets with a maturity exceeding 12 months. These assets are recorded at amortized cost using the effective interest method and are subject to
impairment testing. Financial assets that comply with this definition are: cash and cash-equivalents, fixed term deposits, repurchase agreements, trades and notes receivables, and other debtors.

Fix Term Deposits and Repurchased Agreements: The objective of this instrument is
to maximize short-term cash flow surpluses. This instrument is authorized by Araucos Placement Policy, which establishes a mandate that allows investments in fixed income securities. In general, these instruments have a maturity period of less
than ninety days. Any such instruments that have a maturity period of ninety days or more are not classified as cash.

Trades and Notes Receivable: These represent enforceable rights for Arauco resulting from the normal course of the business,
namely, operation activity or corporate purposes.

Other Debtors: These correspond to receivables from sales, services
or loans that are not considered within the normal course of the business.

Trades receivables are presented at net value,
which means that they are presented net of bad debt estimates. This provision is determined when there is evidence that Arauco will not receive the payments agreed to in the original sales terms. These provisions are carried out when a customer
files for and commences legal bankruptcy proceedings or is in default of payments, or when Arauco has exhausted all debt collection options within a reasonable period. These include telephone calls, e-mails and debt collection letters. In the case
of sales in Chile corresponding to the Companys distribution affiliate Arauco Distribución S.A., the provisions are estimated using a percentage of receivables which is determined on a case by case basis, considering the clients
internal risk classification and the debts aging (days past due).

The following table summarizes Araucos financial
assets at closing balance:

Fair Value Hierarchy

The assets and liabilities recorded at fair value in the Consolidated Balance Sheet dated December 31, 2009 and have been measured
based on the methodologies provided in IAS 39. The methodologies applied for each financial instrument are classified according to their hierarchy as follows:



|- | Level I: Values or quoted prices in active markets for identical assets and liabilities.
|- | ----------------------------------------------------------------------------------------



|- | Level II: Information (Inputs) from other sources than the quoted values of Level I, but observable in the market for assets and liabilities either directly
(prices) or indirectly (derived from prices).
|- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Level III: Inputs for assets or liabilities that are not based on observable market data.
|- | -----------------------------------------------------------------------------------------

Hedging Instruments

Hedging instruments registered at December 31, 2009 correspond to cash flow hedges. Specifically, at the closing balance date, Arauco
recorded rate swaps resulting at fair value for a total of ThU.S.$17,998, which is presented in Equity as Other comprehensive results, net of exchange rate and deferred taxes.

Nature of Risk

Arauco
is exposed to variations in cash flows due to exchange rate risk mainly resulting from having assets in U.S. Dollars and liabilities in UF (obligations to the public), which causes mismatches that could affect operating results.

In order to avoid exchange rate risk, Arauco made two cross-currency swap contracts
listed below:

1.- Cross Currency Swap with Banco de Chile for 1,000,000 UF

With this swap Arauco receives semi-annual interest payments (in March and September) based on a nominal amount of 1,000,000 UF at a 2.25%
annual rate, and pays semi-annual interest (in March and September) based on a notional amount of US$35,700,986.39 (equivalent to 1,000,000 UF at the exchange rate at the date of the contract) at a rate of 4.99%. The market value amounts to
ThU.S.$2,887 at December 31, 2009. Maturity date of this swap is March 1, 2014.

2.- Cross Currency Swap with JPMorgan for
1,000,000 UF

With this contract Arauco receives semi-annual interest payments (in March and September) based on a notional
amount of 1,000,000 UF at an annual rate of 2.25%, and pays semi-annual interest (in March and September) based on a notional amount of U.S.$35,281,193.28 (equivalent to 1,000,000 UF at the exchange rate at the date of the contract) at a rate of
4.94%. The market value amounts to ThU.S.$3,498 at December 31, 2009. The maturity date of this Swap is March 1, 2014.

Through a test of effectiveness, Arauco is able to validate that the instrument is highly effective within an acceptable range for the
Company to eliminate exchange rate uncertainty in commitments from the object of coverage.

Hedging Swaps F Series Bond

Hedging Objective

Arauco
placed a F series bond in November 2008 and, March 2009 for an amount of 7,000,000 UF at an annual rate of 4.25% payable semi-annually. To mitigate the risk of exchange rate, Arauco made four cross-currency swap contracts that partially cover the
bond amount fluctuations:

Contract 1: With this contract Arauco receives semi-annual interest payments (in April and October)
based on a notional amount of 1,000,000 UF at an annual rate of 4.25%, and pays semi-annual interest (in April and October) based on a notional amount of U.S.$38.38 million (equivalent to 1,000,000 UF at the exchange rate at the date of the
contract) at a rate of 5.86%. The market value amounts to ThU.S.$2,503 at December 31, 2009. This contract expires on October 30, 2014.

Contract 2: With this contract Arauco receives semi-annual interest payments (in April and October) based on a notional amount of
1,000,000 UF at an annual rate of 4.25%, and pays semi-annual interest (in April and October) based on a notional amount of U.S.$37.98 million (equivalent to 1,000,000 UF at the exchange rate at the date of the contract) at a rate of 5.79%. The
markets value amounts to ThU.S.$2,781 at December 31, 2009. This contract expires on April 30, 2014.

Contract 3:
With this contract Arauco receives semi-annual interest payments (in April and October) based on a notional amount of 1,000,000 UF at an annual rate of 4.25%, and pays semi-annual interest (in April and October) based on a notional amount of
U.S.$37.98 million (equivalent to 1,000,000 UF at the exchange rate at the date of the contract) at a rate of 5.8%. The markets value amounts to ThU.S.$2,957 at December 31, 2009. This contract expires on October 30, 2014.

Contract 4: With this contract Arauco receives semi-annual interest payments (April and
October) based on a notional amount of 1,000,000 UF at an annual rate of 4.25%, and pays semi-annual interest (in April and October) based on a notional amount of U.S.$37.62 million (equivalent to 1,000,000 UF at the exchange rate at the date of the
contract) at a rate of 5.79%. The markets value amounts to ThU.S.$3,372 at December 31, 2009. This contract expires on October 30, 2014.

Through a test of effectiveness, Arauco can validate that the above-detailed hedging instruments are highly effective within an
acceptable range for the Company to eliminate exchange rate uncertainty for commitments that are the objects of such coverage.

Hedging
Strategy

Given that Arauco holds a high percentage of assets in U.S. Dollars, the Company needs to reduce its exchange
rate risk as it has obligations in adjustable-rate Pesos. The aim of this swap is to eliminate exchange rate uncertainty, exchanging cash flows from adjustable-rate Pesos obligations generated by the above mentioned bonds with U.S. Dollar cash
flows (Araucos functional currency) at a fixed exchange rate and determined at the date of the contract execution.

Valuation Method

Fair value financial assets with changes in Profit and Loss (Negotiation)

Fair value financial assets with changes in profit and loss are initially recognized at fair value and transaction costs are recognized in
the Income Statement. Subsequently, they are recorded at fair value.

Swaps: These are valued using the discounted cash
flow method at a discount rate consistent with operational risk, using specific swap valuation tools that are publicly available.

Forwards:These instruments are initially recognized at fair value at the date on which the contract is entered into and are
subsequently remeasured at fair value. The forwards are recorded as assets when fair value is positive and, as liabilities when fair value is negative.

The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar
maturity profiles.

Loans and Receivables

Their value is recorded at amortized cost using the effective interest rate method, discounting the provision for bad debt. This value is
a reasonable approximation of fair value.

Repurchased Agreements: These are valued at initial investment cost
of the short-term instrument plus interest accrued at the closing date for the period.

Mutual Funds:Given their
nature, they are recognized at market value at the closing date for the period.

These financial instruments are valued using the discount cash flow method at a rate consistent with operational risk using the
information given by each bank as a counterparty.

Financial Liabilities at Amortized Cost

Financial instruments classified in this category are valued at amortized cost using the effective interest rate method.

For informational purposes, the fair value of these financial liabilities is shown. Estimates of bank obligations are determined using
specific valuation techniques using cash flow discounted at rates consistent with the risk of the operation, while bonds are valued at market price.

Financial Liabilities with Changes in Profit and Loss

Swap:These financial instruments are valued using the discounted cash flow method at a rate consistent with the operation risk,
using the information given by each bank as a counterparty.

Risk Management

Araucos financial assets are exposed to several financial risks: credit risk, liquidity risk and market risk (including exchange
rate risks, interest rate risks and price risks). Araucos global risk management program focuses on financial market uncertainty and tries to minimize potential adverse effects over Araucos financial profitability.

Araucos financial risk management is overseen by the Finance Department. This department identifies, assesses and hedges financial
risks in close collaboration with Araucos operational units. The Company does not actively participate in the trading of its financial assets for speculative purposes.

Type of risks that arise from financial instruments

Type of Risk: Credit Risk

Description

Credit risk refers to financial uncertainty at different time horizons concerning the fulfillment of obligations by
counterparties, at the time of exercising contract rights to receive cash or other financial assets on behalf of Arauco.

Explanation of
Risk Exposure and How These Risks Arise

Araucos exposure to credit risk is directly related to each of its
customers individual capacities to fulfill their contractual commitments, reflected in commercial debtor accounts. Furthermore, credit risk also arises for assets that are in the hands of third parties such as fixed term deposits, agreements
and mutual funds.

With regard to trade accounts receivables, as a policy, Arauco holds insurance policies for open account
sales. These are to cover export sales from the Company, Aserraderos Arauco S.A., Paneles Arauco S.A. and Forestal Arauco S.A., as well as local sales of Arauco Distribución S.A., Arauco México S.A. de C.V., Arauco Wood Inc., Arauco
Colombia S.A.,

Arauco Perú S.A. and Alto Paraná S.A. (and affiliates). Arauco works with Continental
Credit Insurance Company (AA- Fitch Ratings). Placas do Paraná and Arauco do Brasil (Brazil) local sales credits are insured with Euler Hermes Insurance Company. These insurance policies cover 90% of the invoice with no deductible.

In order to guarantee a credit line or an advanced payment to a supplier approved by the Credit Committee, Arauco holds
several guarantees, such as mortgages, pledges, standby letters of credit, bank guarantee bonds, checks, promissory notes, consumption loans or any other guarantee that may be needed pursuant to each countrys legislation. Debt covered by this
type of guarantee amounted to U.S.$ 29 million in December 2009. The guarantee procedure is regulated by Araucos Guarantee Policy, which controls accounting and reporting, maturity dates and value.

The Companys maximum credit risk exposure is limited to the amortized cost value of the registered trade accounts receivable, at
the date of this report, less the sales percentage insured by aforementioned credit insurance companies and by the guarantees provided to Arauco.

In 2009, Araucos consolidated sales amounted to ThU.S.$3,113,045, of which 56.69% correspond to credit sales, 32.70% to sales with
letters of credit, and 10.62% to other types of sales, such as Cash Against Documents (CAD) and advance payments.

At December
2009, Araucos Sales Debtors amounted to ThU.S.$506,503 of which 61.44% corresponded to credit sales, 33.29% to sales with letters of credit and 5.27% to other types of sales, such as CAD and advance payments, distributed among 2,459 clients.
The client with the highest open account debt did not exceed 1.99% of total receivables at that date.

The receivables covered
by the different insurance and guarantee policies reaches 88.86%, therefore, Araucos exposure portfolio is 11.14%.

Explanation of Risk Management
Objectives, Policies and Processes, and Measurement Methods

The Credit and Collections Department, which reports to the
Finance Department, is responsible for minimizing receivables credit risk and supervising past due accounts. It is also responsible for the approval or rejection of credit limits for all sales. The standards and procedures governing the control and
risk management of credit sales are set forth in the Companys Credit Policy.

For customer credit line approval and/or
modification, all Arauco group companies must follow an established procedure. All Credit requests are entered into a Credit Evaluation model (EVARIE) where all available information is analyzed, including the credit line given by the credit
insurance company. Subsequently, credit requests are approved or rejected by the internal committee of each company within the Arauco group considering the maximum amount authorized by the Credit Policy Department. If the credit line exceeds the
maximum established amount, it is subsequently analyzed by the Corporate Committee. Credit lines are renewed on a yearly basis.

Sales with letters of credit are mainly from Asia and the Middle East. Credit assessments of the issuing banks are performed
periodically, in order to obtain ratings made by the principal risk classification companies of country and world risk rankings, and of their financial position over the last five years. Depending on this evaluation, it is decided whether the
issuing bank is approved or confirmation is requested.

All sales are controlled by a credit verification system that has set parameters to
block orders from clients who have accumulated past due amounts of a defined percentage of the debt and/or clients who at the time of product delivery have exceeded their credit limit or whose credit has expired.

Of the total accounts receivable, 89.47% is current, 8.47% is between 1 and 15 days past due, 0.54% is between 16 and 30 days past due,
0.64% is between 31 and 60 days past due, 0.56% is between 61 and 90 days past due, 0.01% is between 91 and 180 days past due and 0.30% is more than 180 days late.

The amount

Explanation of any changes to risk exposure or changes in objectives, processes and policies regarding previous years risk management

In March 2009, Arauco implemented a Guarantee Policy in order to control accounting, valuation and expiration dates.

In December 2009, there was an update of the Corporate Credit Policy of Arauco group.

Regarding the risks of fix term deposits, agreements and mutual funds, Arauco has a placement policy that minimizes the risk through
guidelines for management of cash flow surpluses in low-risk institutions.

Investment Policy:

Arauco has an Investment Policy that identifies and limits financial instruments and companies in which Arauco and its subsidiaries are
authorized to invest in, specifically, Celulosa Arauco y Constitución S.A.

The Companys Treasury Department is
centralized with operations in Chile. The Head Office is responsible for carrying out investments, cash flow surplus investments, and short and long term debt subscriptions. Exceptions to this rule are specific investments made through other
companies where authorization is required from the Chief Financial Officer.

With regard to financial instruments, the only
permitted investments are fixed income investments and instruments with adequate liquidity. Each instrument has defined classifications and limits, which depend on duration and on the issuer.

With regard to intermediaries, a methodology is used with the objective of determining
the relative risk level of each bank or entitys financial position and debt and asset security using a point system that gives each subject entity a relative risk ranking. Arauco uses this system to define investment limits.

The required records for evaluation of the various criteria are obtained from official finance statements provided by the banks under
evaluation and from the classification of in-effect short and long term debt securities, as defined by the controlling entity (the Superintendency of Banks and Financial Institutions) and used by risk classification companies authorized by the
controlling entity, which in this case include Fitch Ratings Chile, Humphreys and Feller Rate.

Evaluated criteria are:
Capital and Reserves, Current Ratio, Equity Share in Total Investments in Financial System, Capital Yield, Operational Income Net Profit Ratio, Debt / Capital Ratio and the Risk Classifications of each entity.

Any necessary exceptions regarding investment limits in each particular instrument or entity must have express authorization from
Araucos Chief Financial Officer.

Type of Risk: Liquidity Risk

Description

This risk
corresponds to Araucos ability to fulfill debt obligations at the time of expiration.

Explanation of Risk Exposure and How These
Arise

Araucos exposure to liquidity risk is found mainly in its obligations to the public, banks and financial
institutions, creditors and other payables. These may arise if Arauco is unable to meet net cash flow requirements, which sustain its operations under both normal and exceptional circumstances.

Explanation of Objectives, Policies and Processes for Risk Management, and Measurement Methods

The Finance Management Department constantly monitors the Companys cash flow forecasts based on short and long term forecasts and
available financing alternatives. In order to control the risk level of available financial assets, Arauco follows its investment policy.

Guarantees given

As of the date of these consolidated financial statements, Arauco holds ThU.S.$ 2,566 of financial assets passed to third parties
(beneficiaries), as a direct guarantee. If Arauco does not meet its obligation, the beneficiaries can seek relief under the warranty.

At December 31, 2009, the assets covered by an indirect guarantee amounted to ThU.S.$305,649. The indirect guarantees are given to
protect the obligation assumed by a third party, either a related company (the full guarantee of Celulosa Arauco y Constitución S.A. on APSA bonds amounted to ThU.S.$ 270,000) or an unrelated company (the buy-back operations that guarantee
the obligation of forest service enterprises amounted to ThU.S.$ 31,337, and in the event of default, Arauco can cancel the obligation to obtain the asset exchange contract).

Direct and indirect guarantees granted by Arauco:

Type of Risk: Market Risk  Exchange Rate

Description

This risk
arises from the probability of being affected by exchange rate losses due to the currency in which assets, liabilities and investments are held, but which are not included in the balance sheet of an entity.

Explanation of Risk Exposures and How these Arise

Arauco is exposed to the risk of U.S. Dollar (functional currency) fluctuations for sales, purchases and obligations in other
currencies, such as the Chilean Peso, Brazilian Real or others. In the case of significant exchange rate variations, the Chilean Peso is the currency that represents the main risk.

Explanation of Risk Management Objectives, Policies and Processes, and Measurement Methods

Arauco performs sensitivity analyses to measure the effect of this variable on EBITDA and Profit.

Sensitivity analysis considers a variation of + / - 10% of the exchange rate at December 31, 2009 over the Chilean Peso. This
fluctuation range is considered possible given current market conditions at the closing date. With all other variables at a constant rate, a U.S.Dollar exchange rate variation of + / - 10% in relation to the Chilean Peso would mean a EBITDA an
annual variation of + / - 3.53% on the profit after tax and + / - 0.21% on equity.

The main financial instruments subject to
exchange rate risk are local bonds issued in UF. These are not covered by swaps described in the Hedging chapter.

2009, 8.3% of the Companys bonds and bank loans bear interest at variable rates. A change of + / - 10% interest rate, is considered a possible range of fluctuation. Such market conditions would affect the profit after tax at a rate of + / -
0.48% and + / - 0.03% on equity.

Type of Risk: Market Risk  Price of Pulp

Description

Pulp price
is determined by world and regional market conditions. Prices fluctuate based on demand, production capacity, commercial strategies adopted by large-scale forestry companies, pulp and paper producers and by the availability of substitutes.

Explanation of Risk Exposure and How These Arise

Pulp prices are reflected in operational sales within the income statement and directly affect the net profit for the period.

At December 31, 2009, operational income due to pulp sales accounted for 52% of total sales. Pulp prices are fixed on a monthly
basis in accordance with the market. Forward contracts or other financial instruments are not used for pulp sales.

Explanation of Risk
Management Objectives, Policies and Processes, and Measurement Methods

This risk is approached in different ways. Arauco
has a team of specialists who perform periodic market and competition analyses, providing tools to analyze and evaluate trends and adjust forecasts. Similarly, Arauco performs price sensitivity analysis in order to take the respective safeguards to
confront different scenarios in the best possible manner.

Sensitivity analysis considers a variation of + / - 10% of the
average pulp price, a possible fluctuation range given current market conditions at the date of the closing balance. With all other variables constant, a variation of + / - 10% in the average pulp price would mean a variation on profit after tax of
+ / - 33.32% and + / - 1.92% on equity.

Explanation on the measurements of Earnings, Assets and Liability of Each Segment

Pulp

The Pulp business
unit uses wood exclusively from pine and eucalyptus plantations for the production of different types of wood cellulose or pulp. Bleached pulp is mainly used as raw material for producing printing and writing paper, as well as toilet paper and high
quality wrapping paper. Unbleached pulp is used to produce packing paper, filters, fiber cement products, dielectric paper and others. On the other hand fluff pulp is mainly used in the production of diapers and female hygiene products.

NOTE 25. EVENTS AFTER REPORTING PERIOD (IAS 10)

1) On February 27, 2010, a severe earthquake, followed by a tsunami occurred off the coast of the southern-central region of Chile,
which is an area where the Company maintains its industrial operations. Immediately after the earthquake, all of our production units applied their contingency plans, which involved shutting down operations and evaluating the damage caused to each
facility by the earthquake. As a result of the earthquake and subsequent tsunami, its Mutrún sawmill was completely destroyed. Its other operations have been reopening gradually, with the timing of such reopenings depending on the specific
conditions of the respective mill as well as external factors such as infrastructure conditions, road connectivity, power supply and public safety concerns. As of June 24, 2010, all of its operations were operating except for line 2 of the
Arauco Pulp Mill (Arauco II), which will be reopened once the damages are assessed and repaired.

The suspension of the
Companys operations in Chile resulted in a decrease in sales volumes and adverse effects on our results of operations; however, we have insurance covering part of these losses. Our insurance policies cover damages to our property, plants,
equipment and inventories and for business interruption caused by such damages up to an amount of U.S.$650 million, with a deductible for such damages of U.S.$3.3 million and a deductible of 21 days for business interruption. For the first quarter
of 2010, we recorded a loss for damages of property, plants and equipment and inventories of approximately U.S.$27 million, net of insurance coverage. As the date of this annual report, we cannot determine the total amount of the losses incurred as
a consequence of the earthquake, for which we expect to record more losses in respect thereof in the future.

2) On
February 8, 2010, the Companys Argentinean affiliate Alto Paraná S.A. (APSA) was notified of the administrative ruling issued by the Argentinean National Tax Court instructing it to pay 300,965,382 Argentinean pesos corresponding
to taxes and interest accrued up to December 14, 2007; and 116,942,825 Argentine pesos corresponding to fines. Such amounts result from the rejection of the deductions made by the affiliate regarding Income Taxes applicable to expenses,
interests and exchange rates generated by the debts entered into by the company in 2001.

The Argentine affiliate appealed
this ruling before the respective judicial court, the Cámara de Apelaciones de lo Contencioso Administrativo Federal (Contentious Administrative Matters Federal Appeal Court) (CACAF), arguing that such collections are completely
out of order. On February 15, 2010, APSA appealed this ruling before the CACAF.

On March 18, 2010, the CACAF issued
a court decree in which it ordered the AFIP to refrain from requesting the block of preventive interim relief measures, administratively demand payment, issue debt invoices, or initiate judicial collection actions, including seizure of property and
other executive precautionary measures against APSA until said Court decides the respective precautionary measures.

On
May 13, 2010, the First Courtroom of the Contentious Administrative Matters Federal Appeal Court decided to accept the precautionary measure requested by APSA, ordering to suspend the enforcement of the AFIP resolution until the Court issue the
final decision on this matter. This precautionary measure was granted by the Appeal Court subject to the granting by APSA of a corresponding bond, which was duly granted by APSA.

Based on the opinion of the lawyers of the Argentinean affiliate, there are sustantive
arguments and legal precedents that lead them to believe that the claim submitted before the Superior Courts of Justice of Argentina will prevail.

3) The authorization for the issuance and publication of these consolidated financial statements for the period finished on
December 31, 2009 was approved by the Board of Directors of the Company (the Board) in Extraordinary Session No. 417 dated March 23, 2010.

No other events have occurred between December 31, 2009 and the issuance of these consolidated financial statements that may affect
significantly the financial situation of the Company.
