NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1  BASIS FOR PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, in the opinion of
management, include all adjustments (consisting of normal recurring adjustments, except for other operating credits and charges, net referred to in Note 10) necessary to present fairly, in all material respects, the consolidated financial position,
results of operations and cash flows of LP and its subsidiaries for the interim periods presented. Results of operations for interim periods are not necessarily indicative of results to be expected for an entire year. For those consolidated
subsidiaries in which LPs ownership interest is less than 100%, the outside shareholders interests are shown as non-controlling interest. The Company determined that there was an error in the Statement of Other Comprehensive Income in
the second quarter and six month periods ended June 30, 2009. The impact of this error was to reduce Other Comprehensive Income by $2.6 million and $3.0 million for the quarter and six month periods ended June 30, 2009 and has been
corrected in the accompanying financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in LPs Annual Report on Form 10-K for
the year ended December 31, 2009.

NOTE 2  STOCK-BASED COMPENSATION

For the quarters ended June 30, 2010 and 2009, the total compensation expense related to LPs stock-based compensation plans was $2.2 million
and $2.2 million. For the six month periods ended June 30, 2010 and 2009, the total compensation expense related to LPs stock-based compensation plans was $5.4 million and $4.0 million. At June 30, 2010, 5,837,288 shares were
available under the current stock award plans for stock-based awards. For the six month period ended June 30, 2010, the fair value of the options granted was estimated using the Black-Scholes option-pricing model with the following
weighted-average assumptions: a risk free interest rate of 2.43%; an expected volatility factor for the market price of the Companys common stock of 59.5% (based upon historical volatility over the expected life); a dividend yield of 0.0%; and
an expected life of 5.1 years (based upon historical experience). For the six month period ended June 30, 2009, the fair value of the options granted was estimated using the Black-Scholes option-pricing model with the following
weighted-average assumptions: a risk free interest rate of 1.76%; an expected volatility factor for the market price of the Companys common stock of 49.8% (based upon historical volatility over the expected life); a dividend yield of 0.0%; and
an expected life of 5 years (based upon historical experience). The weighted-average fair value of each option or stock settled stock appreciation right (SSARs) granted during the six month period ended June 30, 2010 and June 30, 2009
was $3.73 and $1.00.

NOTE 3  FAIR VALUE MEASUREMENTS

LPs investments that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy
has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant
other observable inputs and Level 3 includes fair values estimated using significant non-observable inputs.

Available for sale securities measured at fair value as of
June 30, 2010 and December 31, 2009 are auction rate securities recorded in long-term investments on LPs condensed consolidated balance sheets. Due to the lack of observable market quotations on LPs auction rate securities
(ARS) portfolio, LP evaluates the structure of its ARS holdings and current market estimates of fair value, including broker quotations and fair value estimates from issuing banks that rely on Level 3 inputs. These inputs include those that are
based on expected cash flow streams and collateral values, including assessments of counterparty credit quality, default risk underlying the security, discount rates and overall capital market liquidity. The valuation of LPs ARS investment
portfolio is subject to uncertainties that are difficult to predict. Factors that may impact LPs valuation include changes to credit ratings of the securities as well as to the underlying assets supporting those securities, rates of default of
the underlying assets, underlying collateral value, discount rates, counterparty risk and ongoing strength and quality of market credit and liquidity.

Trading securities consist of rabbi trust financial assets which are recorded in other assets in LPs consolidated balance sheets. The rabbi trust
holds the assets of the Louisiana-Pacific Corporation 2004 Executive Deferred Compensation Plan (EDC), a non-qualified deferred compensation plan which allows certain management employees to defer receipt of a portion of their compensation and
contribute such amounts to one or more investment funds. The assets of the rabbi trust are invested in mutual funds and are reported at fair value based on active market quotations, which represent Level 1 inputs.

The following table summarizes assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the periods
ended June 30, 2009 and June 30, 2010.

Carrying amounts reported on the balance sheet for cash, cash equivalents, receivables and accounts payable approximate fair
value due to the short-term maturity of these items.

During the six months ended June 30, 2010, LP recorded an impairment charge of $1.1
million to reduce the carrying value of the assets held for sale to the estimated selling price less selling cost. The valuation of these assets was determined using level one inputs under the market approach.

NOTE 4  EARNINGS PER SHARE

Basic
earnings per share are based on the weighted-average number of shares of common stock outstanding. Diluted earnings per share are based upon the weighted-average number of shares of common stock outstanding plus all potentially dilutive securities
that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires that the effect of potentially dilutive common stock equivalents (employee stock options, stock settled stock
appreciation rights, incentive shares and warrants) be excluded from the calculation of diluted earnings per share for the periods in which losses from continuing operations are reported because the effect is anti-dilutive. The following table sets
forth the computation of basic and diluted earnings per share:

For the quarter and six month period ended June 30, 2010, stock options and SSARs relating to approximately
5.6 million and 5.4 million shares of LP common stock were considered anti-dilutive or not in-the-money for purpose of LPs earnings per share calculation. For the quarter and six month period ended June 30, 2009, stock options,
stock warrants and SSARs relating to approximately 25.0 million and 17.6 million shares of LP common stock were considered anti-dilutive for purposes of LPs earnings per share calculation due to LPs loss position from

NOTE 7  ASSETS HELD FOR SALE

Over the last several years, LP has adopted and implemented plans to sell selected assets in order to improve its operating results. LP is required to
classify assets held for sale which are not part of a discontinued business separately on the face of the financial statements outside of Property, plant and equipment. As of June 30, 2010 and December 31, 2009, LP included
three OSB mills and various non-operating sites in its held for sale category. The current book values of assets held for sale by category is as follows:

LP issued $47.9 million of senior notes in 1997 in a private placement to institutional investors. The $7.9 million
remaining notes are secured by $10.0 million in notes receivable from Sierra Pacific Industries and mature in 2012. In the event of a default by Sierra Pacific Industries, LP is fully liable for the notes payable.

LP issued $348.6 million of senior debt in 1998 in a private placement to institutional investors. The remaining $112.0 million of these notes
($225.4 million at December 31, 2009) mature in principal amounts of $90.0 million in 2013 and $22.0 million in 2018. The remaining notes are secured by $113.7 million ($228.7 million at December 31, 2009) of notes receivable
from Green Diamond Resource Company (Green Diamond). Pursuant to the terms of the notes payable, in the event of a default by Green Diamond, LP would be liable to pay only 10% of the indebtedness represented by the notes payable.

LP issued $368.7 million of senior debt in 2003 in a private placement to unrelated third parties. The notes mature in 2018. The notes are supported by a
bank letter of credit. LPs reimbursement obligations under the letter of credit are secured by $410 million in notes receivable from assets sales. In general, the creditors under this arrangement have no recourse to LPs assets, other
than the notes receivable, However, under certain circumstances, LP may be liable for certain liabilities (including liabilities associated with the marketing or remarketing of the notes payable and reimbursement obligations, which are fully cash
collateralized under the letter of credit supporting the notes payable) in an amount not to exceed 10% of the aggregate principle amount of the notes receivable. LPs maximum exposure in this regard was approximately $41 million as of
June 30, 2010 and December 31, 2009.

LP estimates the senior notes maturing in 2010, included in current portion of long-term debt,
to have a fair market value of $60 million at June 30, 2010 and $ 62.0 million at December 31, 2009 based upon market quotations as compared to a book value of $60 million at June 30, 2010 and December 31, 2009. LP estimates
the senior secured notes maturing in 2017 to have a fair value of $262.0 million as of June 30, 2010 and $263.3 million at December 31, 2009 as compared to a book value of $180.7 million and $ 178.2 million at June 30, 2010 and
December 31, 2009.

Additional descriptions of LPs indebtedness are included in consolidated financial statements and the notes
thereto included in LPs Annual Report on Form 10-K for the year ended December 31, 2009.

NOTE 9  INCOME TAXES

Accounting standards require that LP account for income taxes using the asset and liability approach, which requires the recognition of
deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. This method also requires the recognition of future tax benefits, such as
net operating loss carry forwards and other tax credits. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those



13

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS(Continued)



temporary differences are expected to reverse. Valuation allowances are recorded as necessary to reduce deferred tax assets to the amount thereof that is more likely than not to be realized. The
likelihood of realizing deferred tax assets is evaluated by, among other things, estimating future taxable income to which the deferred tax assets may be applied and assessing the impact of tax planning strategies.

For interim periods, accounting standards require that income tax expense be determined by applying the estimated annual effective income tax rate, by
income component, to year-to-date income or loss at the end of each quarter, then adding or subtracting the impact of changes in reserve requirements or statutory tax rates, if any. Each quarter the income tax accrual is adjusted to the latest
estimate and the difference from the previously accrued year-to-date balance is adjusted to the current quarter.

For the first six
months of 2010, the primary differences between the U.S. statutory rate of 35% and the effective rate applicable to LPs continuing operations relate to state income taxes, the effect of foreign tax rates, the effect of foreign currency
translation, and a discrete adjustment for state income taxes. For the second quarter and first six months of 2009, the primary differences between the U.S. statutory rate of 35% and the effective rate applicable to LPs continuing
operations relate to the Companys foreign debt structure, state income taxes and the effect of foreign tax rates.

The components
and associated estimated effective income tax rates applied to the quarter and six month periods ended June 30, 2010 and 2009 are as follows:

LP and its domestic subsidiaries are subject to U.S. federal income tax as well as income taxes of multiple state
jurisdictions. LPs foreign subsidiaries are subject to income tax in Canada, Chile, Brazil and Peru. Federal income tax examinations for the years through 2006 have been effectively settled. LP remains subject to state and local tax
examinations for the tax years 2005 through 2008. LPs Canadian income tax returns have been audited and effectively settled through 2004.

As of June 30, 2010, LP projects that its deferred tax assets associated with state net operating loss carry forwards may not be fully realized, and
has included a partial valuation allowance of $1.3 million in computing its annual effective tax rate estimate used to determine the tax expense for the period ending June 30, 2010.

If LP were to determine that it would not be able to realize a portion of an existing net deferred tax asset for which there is currently no
valuation allowance, an adjustment to the net deferred tax asset would be charged to earnings in the period in which such determination was made. Conversely, if it were to make a determination that it is more likely than not that an existing
deferred tax asset for which there is currently a valuation allowance would be realized, the related valuation allowance would be reduced and a benefit to earnings would be recorded in the period in which such determination was made.

NOTE 11  TRANSACTIONS WITH AFFILIATES

LP has equity investments in AbitibiBowater-LP (a manufacturer of I-joist) and Canfor-LP (a manufacturer of OSB). LP sells products and raw materials to
the AbitibiBowater-LP entity and purchases products for resale from the AbitibiBowater-LP and Canfor-LP entities. LP eliminates profits on these sales and purchases, to the extent the inventory has not been sold through to third parties, on the
basis of its 50% interest. For the quarters ended June 30, 2010 and 2009, LP sold $2.3 million and $1.8 million of products to AbitibiBowater-LP and purchased $13.3 million and $9.3 million of I-joist from AbitibiBowater-LP. LP also purchased
$30.5 million and $11.5 million of OSB from Canfor-LP during the quarters ended June 30, 2010 and 2009. For the six months ended June 30, 2010 and 2009, LP sold $4.0 million and $2.7 million of products to AbitibiBowater-LP and purchased
$24.0 million and $14.3 million of I-joist from AbitibiBowater-LP. LP also purchased $54.1 million and $18.5 million of OSB from Canfor-LP for the six months ended June 30, 2010 and 2009.

NOTE 12  LEGAL AND ENVIRONMENTAL MATTERS

Certain environmental matters and legal proceedings are discussed below.

Environmental Matters

LP is involved in a number of environmental proceedings and activities, and it may be wholly or partially responsible for known or unknown contamination
existing at a number of other sites at which LP has conducted operations or disposed of wastes. Based on the information currently available, management believes that any fines, penalties or other costs or losses resulting from these matters will
not have a material adverse effect on the financial position, results of operations, cash flows or liquidity of LP.

Antitrust Litigation

On December 1, 2008, LP was named as one of a number of defendants in Bailey Lumber & Supply and 84 Lumber Company v. Georgia-Pacific
Corporation et. al. (Civil Action No. 1:08cv1394) filed in the United States District Court for the Southern District of Mississippi Southern Division. The plaintiffs, who opted out of a class action

settlement of substantially identical claims that was implemented in 2008, seek treble damages alleged to have resulted from a conspiracy among the defendants to fix, raise, maintain and
stabilize the prices at which OSB and Plywood are sold in the United States during the period of 2002 into 2006, in violation of Section 1 of the Sherman Act, 15 U.S.C. §1, together with costs and attorneys fees. LP believes these
allegations are without merit and intends to vigorously defend this suit.

Although the complaint in this opt-out case does not specify the
amount of damages sought, a damages model subsequently filed by the plaintiffs suggests that they may be seeking damages in a range from $149 million to $174 million (or $447 million to $524 million if trebled). LP has not increased its reserves for
this opt-out case as a result of the filing of the damages model. LP believes that the resolution of this matter will not have a material adverse effect on LPs financial position, results of operations or cash flows.

ARS litigation

On July 31, 2009, LP filed suit In The United States District Court For The Northern District Of California captioned., Louisiana Pacific Corporation
v. Money Market 1 Institutional Investment Dealer; Merrill Lynch & CO., Inc.; Merrill Lynch, Pierce, Fenner & Smith Incorporated; And Deutsche Bank Securities Inc. (Civil Action No.09cv3529). This matter arose out of LPs
acquisition of certain ARS structured and underwritten by Merrill Lynch and Deutsche Bank with an approximate par value of $145.9 million. In the lawsuit, LP alleges that the defendants made misrepresentations and omissions of material facts in
connection with the issuance of and the auctions for the ARS which constitute a violation of both state and federal securities laws, as well as common law fraud. LP seeks recovery of compensatory damages, rescission of the purchase of the securities
at par value, consequential damages, punitive damages, attorneys fees and any other damages the court deems appropriate under the circumstances.

Other Proceedings

LP is party to other legal proceedings. Based on the information currently available, LP believes that the resolution of such proceedings will not have a
material adverse effect on its financial position, results of operations, cash flows or liquidity.

NOTE 13  SELECTED SEGMENT DATA

LP operates in three segments: Oriented Strand Board (OSB); Siding; and Engineered Wood Products (EWP). LPs business units have been
aggregated into these three segments based upon the similarity of economic characteristics, customers and distribution methods. LPs results of operations are summarized below for each of these segments separately as well as for the
other category which comprises other products that are not individually significant. Segment information was prepared in accordance with the same accounting principles as those described in Note 1 of the Notes to the financial statements
included in LPs Annual Report on Form 10-K for the year ended December 31, 2009.

NOTE 14  POTENTIAL IMPAIRMENTS

LP continues to review certain operations and investments for potential impairments. LPs management currently believes it has adequate support for
the carrying value of each of these operations and investments based upon the anticipated cash flows that result from estimates of future demand, pricing and production costs assuming certain levels of planned capital expenditures. As of
June 30, 2010, the undiscounted cash flows for the facilities indefinitely curtailed support the conclusion that no impairment is necessary for those facilities. However, should demand and pricing for the relevant products be at levels
significantly below cycle average demand and pricing, or should LP decide to invest capital in alternative projects, it is possible that impairment charges will be required.

LP also reviews from time to time possible dispositions of various assets in light of current and anticipated economic and industry conditions, its
strategic plan and other relevant circumstances. Because a determination to dispose of particular assets can require management to make assumptions regarding the transaction structure of the disposition and to estimate the net sales proceeds, which
may be less than previous estimates of undiscounted future net cash flows, LP may be required to record impairment charges in connection with decisions to dispose of assets.

NOTE 15  CONTINGENCY RESERVES

LP
is involved in various legal proceedings incidental to LPs business and is subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which it operates. LP maintains reserves for these various
contingencies as follows:

Hardboard Siding Reserves

LP has established reserves relating to certain liabilities associated with a settlement agreement resulting from a nationwide class action lawsuit
involving hardboard siding manufactured or sold by corporations acquired by LP in 1999 and installed prior to May 15, 2000 which was approved by the applicable courts in 2000. This settlement is discussed in greater detail in the Notes to the
financial statements included in LPs Annual Report on Form 10-K for the year ended December 31, 2009. LP believes that the reserve balance for this settlement at June 30, 2010 will be adequate to cover future payments to claimants
and related administrative costs.

The activity in the portion of LPs loss contingency reserves relating to hardboard siding
contingencies for the first quarters of 2010 and 2009 are summarized in the following table.

As of January 1, 2010, LP froze future contribution credits to its qualified U.S. defined benefit pension plans.
Through June 30, 2010 and 2009, LP recognized $3.8 million and $5.0 million of pension expense, respectively, for all of LPs defined benefit plans. LP presently anticipates recognizing an additional $2.6 million of pension expense in the
remainder of 2010 for a total of $6.4 million.

Through June 30, 2010, LP made no significant pension contributions for LPs defined
benefit plans. LP presently anticipates making approximately $10 to 12 million additional pension contributions for the plans during the remainder of 2010.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS(Continued)



NOTE 17  GUARANTEES AND INDEMNIFICATIONS

LP is a party to contracts in which LP agrees to indemnify third parties for certain liabilities that arise out of or relate to the subject matter of the
contract. In some cases, this indemnity extends to liabilities arising out of the negligence of the indemnified parties, but usually excludes any liabilities caused by gross negligence or willful misconduct of the indemnified parties. LP cannot
estimate the potential amount of future payments under these agreements until events arise that would trigger the liability. See Note 23 of the Notes to the financial statements included in LPs Annual Report on Form 10-K for the year ended
December 31, 2009 for further discussion of LPs guarantees and indemnifications.

Additionally, LP provides warranties on the sale
of most of its products and records an accrual for estimated future claims. Such accruals are based upon historical experience and managements estimate of the level of future claims. The activity in warranty reserves for the second quarter and
first six months of 2010 and 2009 are summarized in the following table:

The current portion of the warranty reserve is included in the caption Accounts payable and accrued liabilities
and the long-term portion is included in the caption Other long-term liabilities on LPs Condensed Consolidated Balance Sheets.

NOTE 18  RECENT AND PROSPECTIVE ACCOUNTING PRONOUNCEMENTS

In June 2009, the FASB issued guidance now codified under ASC Topic 860, Transfers and Servicing (ASC 860) and ASC Topic 810
Consolidation. Under ASC 860, the concept of a qualifying special-purpose entity (QSPE) is no longer relevant for accounting purposes, and formerly qualifying special purpose entities need to be evaluated for consolidation. ASC 810
requires an enterprise to perform an analysis to determine whether the enterprises variable interest gives it a controlling financial interest. As of January 1, 2010, LP adopted ASC 860 and 810 and consolidated the former QSPE established
in connection with the sale of southern timber and timberlands in 2003. The consolidation of the former QSPE results in adjustments to LPs consolidated financial statements to increase LPs assets by $368.1 million, to increase LPs
liabilities by $368.9 million and to reduce LPs net equity by $0.8 million. Specifically, Notes receivable from asset sales increased by $410 million; Advances to and investments in affiliates declined by $44.5 million;
Restricted cash increased $1.6 million; Deferred debt cost increased by $0.9 million; Accounts payable and accrued liabilities increased by $0.2 million; Long-term debt increased by $368.7 million and
Retained earnings declined of $0.8 million. The retroactive application of ASC 860 and 810 resulted in the recognition of additional net loss for the six months ended June 30, 2009 of $0.2 million.

NOTE 19  IMMATERIAL RESTATEMENT

During the third quarter of 2009, the Company determined that there was an error in the Statement of Other Comprehensive Income in the second quarter and
six month periods ended June 30, 2009. The impact of this error was to reduce Other Comprehensive Income by $2.6 million and $3.0 million for the quarter and six month periods ended June 30, 2009 and has been corrected in the accompanying
financial statements.

During the second quarter of 2010, LP identified an error in the calculation of the Equity in income (losses) of
affiliates relating to the foreign currency translation of income and losses of LPs foreign joint ventures. This error was related to foreign currency rates applied to depreciation expense which is included as a component of Equity in
income and losses of unconsolidated affiliates. As Equity in income (losses) of unconsolidated affiliates is a noncash item, this error did not impact net cash provided by (used in) operations in any period. This error resulted in
the understatement of Equity in (income) losses in unconsolidated affiliates in the amount of $0.6 million, $1.4 million and $1.9 million for the years ended December 31, 2009, December 31, 2008 and December 31, 2007
and the remaining in previous years with an accumulated understatement of the Investment in and advances to affiliates in the amounts of $4.8 million and $4.2 million as of December 31, 2009 and December 31, 2008. Since

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS(Continued)



this adjustment is related to the foreign currency process, there is no impact on LPs tax provision or related tax accounts.

LP believes the correction of the error is not material to its previously issued historical financial statements. However, given LPs financial
results through the second quarter of 2010, the error would be material to LPs current results and therefore LP made the decision to correct the error though an immaterial restatement of the previously issued financial statements. The impact
on the second quarter and first six months of 2009 is insignificant. The effects of this restatement on the audited Consolidated Balance sheet as previously presented in LPs Form 10-K as of December 31, 2009 is as follows:

|Item 2. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

GENERAL

Our products are used primarily
in new home construction, repair and remodeling, and manufactured housing. We also market and sell our products in light industrial and commercial construction and we have a modest export business. Our manufacturing facilities are primarily located
in the U.S. and Canada, but we also operate two facilities in Chile and have a 75% ownership interest in a Brazilian facility.

To serve our
markets, we operate in three segments: Oriented Strand Board (OSB), Siding, and Engineered Wood Products (EWP).

Demand for our products
correlates to a significant degree to the level of residential construction activity in North America, which historically has been characterized by significant cyclicality. For the six months of 2010, the U.S. Department of Census reported that
actual single and multi-family housing starts were about 14% higher than for the same period of 2009. We believe the improved level of building, while significantly below normal levels, is related to the slightly improving U.S. economy
and certain housing initiatives by the U.S. government. Our increase in sales is higher than the increase in housing starts due to significant inventory reductions taken by our customers during 2009 in response to the global recession and a
subsequent attempt to build inventory in the first two quarters of 2010 due to anticipated seasonal building activity. During the second quarter, OSB prices were much stronger than in previous periods. Building activity is unlikely to improve to
normal levels until the number of homes available for sale is reduced, foreclosure activity subsides, employment improves and housing prices stabilize further.

OSB is sold as a commodity for which sales prices fluctuate daily based on market factors over which we have little or no control. We cannot predict
whether the prices of our products will remain at current levels or increase or decrease in the future.

For additional factors affecting our
results, refer to the Management Discussion and Analysis overview contained in our Annual Report on Form 10-K for the year ended December 31, 2009 and to About Forward-Looking Statements and Risk Factors in this report.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES

Presented in Note 1 of the Notes to the financial statements included in LPs Annual Report on Form 10-K for the year ended December 31, 2009 is
a discussion of our significant accounting policies and significant accounting estimates and judgments. Throughout the preparation of the financial statements, we employ significant judgments in the application of accounting principles and methods.
These judgments are primarily related to the assumptions used to arrive at various estimates. For the first six months of 2010, these significant accounting estimates and judgments include:

Auction Rate Securities: Our auction-rate securities represent interests in collateralized debt obligations, a portion of which are supported
by pools of residential and commercial mortgages, credit-linked notes, bank trust preferred notes and other securities. Historically, liquidity for these auction-rate securities was typically provided by an auction process that reset the applicable
interest rate at pre-determined intervals, usually every 7, 28, 35 or 90 days. As of June 30, 2010, auction-rate securities that we hold had experienced multiple failed auctions as the amount of securities for sale exceeded the amount of
purchase orders. Consequently, we have classified $34.1 million ($96.8 million, par value) of auction-rate securities as long-term available-for-sale securities.

Our estimates of the valuation of our current holdings of auction rate securities are based upon our evaluation of the structure of our auction rate
securities and current market estimates of fair value, including fair value estimates from the issuing banks and indicative pricing from other parties. We review several factors to determine whether a loss is other-than-temporary. These factors
include but are not limited to: (i) the length of time a security is in an unrealized loss position, (ii) the extent to which fair value is less than cost, (iii) the financial condition and near term prospects of the issuer, and
(iv) our intent and ability to hold the security for a period of time sufficient to allow for any



21



---

anticipated recovery in fair value. Due to the numerous variables associated with these judgments, both the precision and reliability of the resulting estimates of the related valuation allowance
are subject to substantial uncertainties. We regularly monitor our estimated exposure to these investments and, as additional information becomes known, may change our estimates significantly.

Legal Contingencies. Our estimates of loss contingencies for legal proceedings are based on various judgments and assumptions regarding the
potential resolution or disposition of the underlying claims and associated costs. In making judgments and assumptions regarding legal contingencies for ongoing class action settlements, we consider, among other things, discernible trends in the
rate of claims asserted and related damage estimates and information obtained through consultation with statisticians and economists, including statistical analyses of potential outcomes based on experience to date and the experience of third
parties who have been subject to product-related claims judged to be comparable. Due to the numerous variables associated with these judgments and assumptions, both the precision and reliability of the resulting estimates of the related loss
contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to these contingencies and, as additional information becomes known, may change our estimates significantly.

Environmental Contingencies. Our estimates of loss contingencies for environmental matters are based on various judgments and assumptions. These
estimates typically reflect judgments and assumptions relating to the probable nature, magnitude and timing of required investigation, remediation and/or monitoring activities and the probable cost of these activities, and in some cases reflect
judgments and assumptions relating to the obligation or willingness and ability of third parties to bear a proportionate or allocated share of the cost of these activities, including third parties who purchased assets from us subject to
environmental liabilities. We consider the ability of third parties to pay their apportioned cost when developing our estimates. In making these judgments and assumptions related to the development of our loss contingencies, we consider, among other
things, the activity to date at particular sites, information obtained through consultation with applicable regulatory authorities and third-party consultants and contractors and our historical experience at other sites that are judged to be
comparable. Due to the numerous variables associated with these judgments and assumptions, and the effects of changes in governmental regulation and environmental technologies, both the precision and reliability of the resulting estimates of the
related contingencies are subject to substantial uncertainties. We regularly monitor our estimated exposure to environmental loss contingencies and, as additional information becomes known, may change our estimates significantly. At June 30,
2010, we excluded from our estimates approximately $1.0 million of potential environmental liabilities that we estimate will be allocated to third parties pursuant to existing and anticipated future cost sharing arrangements.

Impairment of Long-Lived Assets. We review the long-lived assets held and used by us (primarily property, plant and equipment and timber and
timberlands) for impairment when events or changes in circumstances indicate that the carrying amount of assets may not be recoverable. We consider the necessity of undertaking such a review at least quarterly, and also when certain events or
changes in circumstances occur. Events and changes in circumstances that may necessitate such a review may include, but are not limited to: a significant decrease in the market price of a long-lived asset or group of long-lived assets; a significant
adverse change in the extent or manner in which a long-lived asset or group of long-lived assets is being used or in its physical condition; a significant adverse change in legal factors or in the business climate that could affect the value of a
long-lived asset or group of long-lived assets, including an adverse action or assessment by a regulator; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset or
group of long-lived assets; current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or group of
long-lived assets; and a current expectation that, more likely than not, a long-lived asset or group of long-lived assets will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. Identifying these
events and changes in circumstances, and assessing their impact on the appropriate valuation of the affected assets under accounting principles generally accepted in the U.S., requires us to make judgments, assumptions and estimates.

In general, for assets held and used in our operations, impairments are recognized when the carrying amount of the long-lived asset or groups of
long-lived assets is not recoverable and exceeds the fair value of the asset or groups of assets. The carrying amount of a long-lived asset or groups of long-lived assets is not recoverable if it exceeds the sum of the undiscounted cash flows
expected to result from the use and eventual disposition of the assets or group of assets. The key assumptions in estimating these cash flows relate to future production volumes, pricing of



22



---

commodity or specialty products and future estimates of expenses to be incurred as reflected in our long-range internal planning models. Our assumptions regarding pricing are based upon the
average pricing over the commodity cycle (generally five years) due to the inherent volatility of commodity product pricing, and reflect our assessment of information gathered from industry research firms, research reports published by investment
analysts and other published forecasts. Our assumptions regarding expenses reflect our expectation that we will continue to reduce production costs to offset inflationary impacts.

When impairment is indicated for assets held and used in our operations, the book values of the affected assets are written down to their estimated fair
value, which is generally based upon discounted future cash flows associated with the affected assets. When impairment is indicated for assets to be disposed of, the book values of the affected assets are written down to their estimated fair value,
less estimated selling costs. Consequently, a determination to dispose of particular assets can require us to estimate the net sales proceeds expected to be realized upon such disposition, which may be less than the estimated undiscounted future net
cash flows associated with such assets prior to such determination, and thus require an impairment charge. In situations where we have experience in selling assets of a similar nature, we may estimate net sales proceeds on the basis of that
experience. In other situations, we hire independent appraisers to estimate net sales proceeds.

Due to the numerous variables associated with
our judgments and assumptions relating to the valuation of assets in these circumstances, and the effects of changes in circumstances affecting these valuations, both the precision and reliability of the resulting estimates of the related impairment
charges are subject to substantial uncertainties and, as additional information becomes known, we may change our estimates significantly.

Income Taxes. The determination of the provision for income taxes, and the resulting current and deferred tax assets and liabilities, involves
significant management judgment, and is based upon information and estimates available to management at the time of such determination. The final income tax liability to any taxing jurisdiction with respect to any calendar year will ultimately be
determined long after our financial statements have been published for that year. We maintain reserves for known estimated tax exposures in federal, state and international jurisdictions; however, actual results may differ materially from our
estimates.

Judgment is also applied in determining whether deferred tax assets will be realized in full or in part. When we consider it to be
more likely than not that all or some portion of a deferred tax asset will not be realized, a valuation allowance is established for the amount of the deferred tax asset that is estimated not to be realizable. As of June 30, 2010, we had
established valuation allowances against certain deferred tax assets, primarily related to state and foreign carryovers of net operating losses, credits and capital losses. We have not established valuation allowances against other deferred tax
assets based upon tax strategies planned to mitigate the risk of impairment of these assets. Accordingly, changes in facts or circumstances affecting the likelihood of realizing a deferred tax asset could result in the need to record additional
valuation allowances.

Pension Plans. Most of our U.S. employees and many of our Canadian employees participate in defined
benefit pension plans sponsored by LP. We account for the consequences of our sponsorship of these plans in accordance with accounting principles generally accepted in the U.S., which require us to make actuarial assumptions that are used
to calculate the related assets, liabilities and expenses recorded in our financial statements. While we believe we have a reasonable basis for these assumptions, which include assumptions regarding long-term rates of return on plan
assets, life expectancies, rates of increase in salary levels, rates at which future values should be discounted to determine present values and other matters, the amounts of our pension related assets, liabilities and expenses recorded in our
financial statements would differ if we used other assumptions.

Workers Compensation. We are self insured for most of
our U.S. employees workers compensation claims. We account for these plans in accordance with accounting principles generally accepted in the U.S., which require us to make actuarial assumptions that are used to calculate the related
assets, liabilities and expenses recorded in our financial statements. While we believe we have a reasonable basis for these assumptions, which include assumptions regarding rates at which future values should be discounted to determine
present values, expected future health care costs and other matters. The amounts of our liabilities and related expenses recorded in our financial statements would differ if we used other assumptions.

NON-GAAP FINANCIAL MEASURES

In evaluating our business, we utilize several non-GAAP financial measures. A non-GAAP financial measure is generally defined by the SEC as one that
purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so excluded or included under applicable GAAP guidance. In this report on Form 10-Q, we disclose
earnings from continuing operations before interest expense, taxes, depreciation and amortization (EBITDA from continuing operations) which is a non-GAAP financial measure. Additionally, we disclose Adjusted EBITDA from continuing
operations which further adjusts EBITDA from continuing operations to exclude stock based compensation expense, (gain) loss on sales or impairment of long lived assets, other operating charges and credits, other than temporary investment impairment,
early debt extinguishment and investment income. Neither EBITDA from continuing operations nor adjusted EBITDA from continuing operations are a substitute for the GAAP measures of net income or operating cash flows or for any other GAAP measures of
operating performance or liquidity.

We have included EBITDA from continuing operations and adjusted EBITDA from continuing operations in this
report on Form 10-Q because we use them as important supplemental measures of our performance and believe that they are frequently used by securities analysts, investors and other interested persons in the evaluation of companies in our industry,
some of which present EBITDA when reporting their results. We use EBITDA from continuing operations and adjusted EBITDA from continuing operations to evaluate our performance as compared to other companies in our industry that have different
financing and capital structures and/or tax rates. It should be noted that companies calculate EBITDA and adjusted EBITDA differently and, therefore, our EBITDA and adjusted EBITDA measures may not be comparable to EBITDA and adjusted EBITDA
reported by other companies. Our EBITDA and adjusted EBITDA measures have material limitations as performance measures because they exclude interest expense, income tax (benefit) expense and depreciation and amortization which are necessary to
operate our business or which we otherwise incurred or experienced in connection with the operation of our business.

The following table
represents significant items by operating segment and reconciles income (loss) from continuing operations to adjusted EBITDA from continuing operations:

For both the quarter and the
six month period ended June 30, 2010, OSB prices increased compared to the corresponding periods of 2009. The increase in OSB prices was likely due to tightening of the gap between supply and demand based upon currently operating facilities
across the industry as well as raw material shortages due to weather related issues. The increase in selling price favorably impacted net sales and operating losses by approximately $72 million for the quarter and $87 million for the six month
period as compared to the corresponding periods of 2009. As compared to the corresponding periods of 2009, the increase in sales volume was primarily due to increased demand as well as inventory restocking by our customers after dramatic declines in
2009. To balance supply and demand, we continue to have two of our ten OSB mills curtailed.

---

Compared to the second quarter and first six months of 2009, the primary factor that led to improved
operating results was the increase in commodity OSB sales prices. This increase was offset by an increase in our Canadian dollar denominated manufacturing costs and certain raw materials. The Canadian dollar has strengthened significantly from the
corresponding periods of 2009, which causes our Canadian production costs stated in U.S. dollars to increase.

SIDING

Our siding segment produces and markets wood-based siding and related accessories, together with commodity OSB products from one mill.

Segment sales, operating profits and adjusted EBITDA from continuing operations for this segment are as follows:

For the second quarter and
first six months of 2010 compared to the corresponding periods in 2009, sales volumes increased significantly in our SmartSide siding line due to improvement in both retail sales and housing starts as well as an inventory build in the sales
channels. In our Canexel siding lines, sales volumes declined due to the curtailment of certain production lines. Sales prices in our SmartSide siding product line for the quarter and six month period ended June 30, 2010 as compared to the
corresponding periods of 2009 changed slightly due to product mix with specific product prices remaining generally constant. In our Canexel product line, sales prices increased in the second quarter and first six months as compared to the
corresponding period of 2009 due to the impact of the strengthening Canadian dollar as a majority of these sales are made in Canada. Sales prices increased in our commodity OSB products as discussed in the OSB segment above.

Overall, the improvement in operating results for our siding segment for the second quarter and first six
months of 2010 compared to the same periods of 2009 was primarily due to increased sales volumes and improvements in OSB pricing.

During the second quarter and
first six months of 2010 compared to the corresponding periods of 2009, we saw increases in sales volumes in both LVL/LSL and I-Joist due to increased housing demand as well as customer inventory increases. Net average selling prices increased in
I-Joist due to price adjustments implemented in the early part of the second quarter of 2010 and increases in LVL/LSL due to changes in product mix. Our focus in the EWP segment continues to be on reductions in conversion costs, better geographic
manufacturing and distribution, and maintaining key customer relationships. Included in this segment is a plywood operation, which primarily produces plywood as a by-product from the LVL production process.

For the second quarter and first six months of 2010 compared to the corresponding periods of 2009, the results of operations for EWP improved due to
higher sales volume and prices and improvements in our LSL facility, which were partially offset by higher raw material costs.

OTHER PRODUCTS

Our other products category includes a moulding business, Chilean and Brazilian operations, export sales and a joint venture that produces and sells
cellulose insulation. This category also includes remaining timber and timberlands and other minor products, services and operations closed prior to January 1, 2002.

For the second quarter and first six months of 2010 compared to the corresponding periods of 2009, sales in our
moulding operation were higher due to increased retail demand and sales in Chilean and Brazilian operations increased as we continued to penetrate local markets, in response to the rebuilding efforts resulting from the Chilean earthquake.

Overall, operating results associated with these activities were positively impacted by improvements in our Chilean and Brazilian operations
and the performance of our U.S. Greenfiber joint venture.

GENERAL CORPORATE AND OTHER EXPENSE, NET

For the second quarter of 2010 compared to the corresponding period of 2009, general corporate expenses and overall selling and administrative have
remained relatively flat. For the first six months of 2010 compared to the corresponding period of 2009, general corporate expenses were flat and overall selling and administrative expenses increased by 4 percent. General corporate and other
expenses primarily consist of corporate overhead such as wages and benefits for corporate and sales personnel, professional fees, insurance and other expenses. Overall selling and administrative expenses increased in the first six months of 2010 as
compared to the first six months of 2010 due to several one-time benefits received in the first quarter of 2009 which did not occur in the first quarter of 2010 as well as increases in marketing and sales based upon the increased demand across
product lines.

INTEREST EXPENSE AND INVESTMENT INCOME

Investment income in the second quarter and first six months of 2010 was lower compared to the corresponding periods of 2009 due to lower returns on
investments, including both interest and market valuations. Interest expense was lower in the second quarter of 2010 due to our repurchase in the third quarter of 2009 of some of our debt that was issued in the first quarter of 2009. Interest
expense for the six month period ended June 30, 2010 compared to the same period of 2009 was relatively flat.

INCOME TAXES

Accounting standards require that we account for income taxes using the asset and liability approach, which requires the recognition of deferred tax
assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. This method also requires the recognition of future tax benefits, such as net
operating loss carry forwards and other tax credits. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Valuation
allowances are recorded as necessary to reduce deferred tax assets to the amount thereof that is more likely than not to be realized. The likelihood of realizing deferred tax assets is evaluated by, among other things, estimating future taxable
income to which the deferred tax assets may be applied and assessing the impact of tax planning strategies.

---

For interim periods, accounting standards require that income tax expense be determined by applying the
estimated annual effective income tax rate, by income component, to year-to-date income or loss at the end of each quarter, then adding or subtracting the impact of changes in reserve requirements or statutory tax rates, if any. Each quarter the
income tax accrual is adjusted to the latest estimate and the difference from the previously accrued year-to-date balance is adjusted to the current quarter.

For the first six months of 2010, the primary differences between the U.S. statutory rate of 35% and the effective rate applicable to our continuing
operations relate to state income taxes, the effect of foreign tax rates, the effect of foreign currency translation, and a discrete adjustment for state income taxes. For the second quarter and first six months of 2009, the primary
differences between the U.S. statutory rate of 35% and the effective rate applicable to our continuing operations relate to the Companys foreign debt structure, state income taxes and the effect of foreign tax rates.

The components and associated estimated effective income tax rates applied to the quarter and six month period ended June 30, 2010 and 2009 are as
follows:

We and our domestic subsidiaries are subject to U.S. federal income tax as well as income taxes of multiple state
jurisdictions. Our foreign subsidiaries are subject to income tax in Canada, Chile, Brazil and Peru. Federal income tax examinations for the years through 2006 have been effectively settled. LP remains subject to state and local tax examinations for
the tax years 2005 through 2008. Our Canadian returns have been audited and effectively settled through 2004.

If we were to determine that we
would not be able to realize a portion of an existing net deferred tax asset for which there is currently no valuation allowance, an adjustment to the net deferred tax asset would be charged to earnings in the period in which such determination
was made. Conversely, if we were to make a determination that it is more likely than not that an existing deferred tax asset for which there is currently a valuation allowance would be realized, the related valuation allowance would be reduced and a
benefit to earnings would be recorded in the period in which such determination was made.

DEFINED BENEFIT PENSION PLANS

We maintain several qualified and non-qualified defined benefit pension plans in the U.S. and Canada that cover a substantial portion
of our employees. See Note 15 of the Notes to financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009 for further information on our plans. We estimate that our net periodic pension cost for 2010
will be approximately $6.4 million. If a curtailment or settlement occurs in 2010, this estimate may change significantly. We estimate that we will contribute approximately $10 to $12 million to our defined benefit pension plans in 2010. At
December 31, 2009, we had $104.2 million of net actuarial loss and $1.4 million of prior service cost included in accumulated other comprehensive loss. Of these amounts, we expect to recognize a net actuarial loss of $4.5 million as a component
of net periodic pension cost in 2010, which will account for approximately 71% of our estimated 2010 net periodic pension cost.

HARDBOARD SIDING LITIGATION UPDATE

The following update should be read in conjunction with the discussion of our hardboard siding litigation set forth in Note 20 of the Notes to financial
statements included in our Annual Report on Form 10-K for the year ended December 31, 2009.

The average payment amount for
settled claims as of June 30, 2010, March 31, 2010 and December 31, 2009 was $1,000, $1,000 and $1,100. Dismissal of claims is typically the result of claims for product not produced by LP or predecessor companies or claims that
lack sufficient information or documentation after repeated efforts to correct those deficiencies.

LIQUIDITY AND CAPITAL RESOURCES

OVERVIEW

Our principal sources of liquidity are existing cash and investment balances, cash generated by our operations and our ability to borrow under credit
facilities. We may also from time to time issue and sell equity, debt or hybrid securities or engage in other capital market transactions.

Our principal uses of liquidity are paying the costs and expenses associated with our operations, servicing outstanding indebtedness and making capital
expenditures. We may also from time to time prepay or repurchase outstanding indebtedness, repurchase shares of our common stock and acquire assets or businesses that are complementary to our operations. Any such repurchases may be commenced,
suspended, discontinued or resumed, and the method or methods of effecting any such repurchases may be changed, at any time or from time to time without prior notice.

We expect to be able to meet the future cash requirements of our existing businesses through cash expected to be generated from operations, existing cash
and investment balances, existing credit facilities and other capital resources. The following discussion provides further details of our liquidity and capital resources.

OPERATING ACTIVITIES

During the first six months of 2010, we generated $35.6 million of cash from operating activities compared to $42.9 million in the first six months of
2009. The decline in cash provided from operating activities in the first six months of 2010 resulted primarily from reduced operating losses which were more than offset by lower income tax refunds and an increase in working capital.

During the first six months of 2010, our accounts receivable increased significantly due to higher sales volume across all product lines and increased
sales prices related to commodity OSB. No substantial change in credit terms or number of days outstanding occurred. Inventory increased based upon expected future demand. Accounts payable remained relatively constant between periods.



32



---

INVESTING ACTIVITIES

During the first six months of 2010, we generated approximately $122.2 million of cash from investing activities. Capital expenditures in the first six
months of 2010 were $5.4 million. Additionally, we received reimbursement of $6.1 million previously contributed to our joint ventures for working capital requirements and received $1.2 million in the sale of assets. We received $115.1 million in
principal payments on our notes receivable from asset sales. Restricted cash was reduced by $5.2 million. Included in Accounts payable is $1.5 million related to capital expenditures that had not yet been paid as of June 30, 2010.

During the first six months of 2009, we generated approximately $58.2 million from investing activities. Capital expenditures in the first
six months of 2009 were $4.7 million. Additionally, we contributed $1.4 million to our joint ventures for working capital requirements and received $5.2 million on the sale of assets. We also received $21.5 million in proceeds on the sale of
investments with maturities in excess of 90 days. Restricted cash was reduced by $37.6 million during the first six months of 2009. Included in Accounts payable is $0.5 million related to capital expenditures that had not yet been paid
as of June 30, 2009.

Capital expenditures for existing facilities and investments in existing joint ventures for 2010 are expected to
total about $20 to $25 million.

FINANCING ACTIVITIES

During the first six months of 2010, we repaid $113.4 million of our limited recourse notes payable.

In the first quarter of 2009, we issued and sold 375,000 Units consisting of (1) $375,000,000 principal amount at maturity of 13% Senior Secured
Notes due 2017 and (2) warrants to purchase 18,395,963 shares of our common stock at an exercise price of $1.39 per share, subject to adjustment in certain circumstances and to mandatory cashless exercise provisions. The issuance and sale of
the Units generated gross proceeds of $281.3 million, reflecting original issue discounts of $93.7 million, of which $126.6 million was used to retire $126.0 million aggregate principal amount of our 8.875% Senior Notes due 2010 and $14.5 million
which was used to pay related transaction costs. An additional $1.0 million of debt issuance costs were paid in the second quarter of 2009.

CREDIT AGREEMENTS

We have a credit facility which provides for a committed asset-based borrowing capacity of up to $100 million, with a $60 million sublimit for U.S.
letters of credit and a $10 million sublimit for Canadian letters of credit. The credit facility will end in September of 2012, so long as we maintain on deposit with the agent for the credit facility at all times until our 8.875% Senior Notes due
August 15, 2010 have been paid in full an amount of cash or cash equivalents sufficient to pay all principal of and interest on such Notes when due and satisfy certain other conditions (with any failure to do so being an event of default under
the credit facility). As of June 30, 2010, the principal amount outstanding under such Notes was $60 million.

The availability of credit
under the credit facility is subject to a borrowing base, which is calculated based on certain percentages of accounts receivable and inventory and at any given time may limit the amount of borrowings and letters of credit otherwise available under
the facility. In addition, the credit facility contains a covenant requiring us to maintain a fixed charge coverage ratio of at least 1.1 to 1.0 at any time that our unused borrowing base capacity after adjustment to exclude certain past due trade
payables falls below $50 million. At June 30, 2010, we had $76.0 million of unused borrowing base capacity under the credit facility, resulting from a borrowing base of $90.6 million less $14.6 million of outstanding non-cash collateralized
letters of credit. However, because our fixed charge coverage ratio at June 30, 2010 was less than 1.1 to 1.0 we were effectively precluded from utilizing $50 million of this capacity (other than cash-collateralized letters of credit, as
described below, subject to the applicable letter of credit sublimits). The credit facility allows LP to pledge, as security for its reimbursement obligations in respect of letters of credit issued under the facility, cash collateral in an amount
not less than 105% of the of the stated amount of such letters of credit. The above-described preclusion to our utilization of $50 million of the capacity otherwise available under the facility does not apply to such cash collateralized letters of
credit. At June 30, 2010, we had no borrowings outstanding under the facility. In addition to the $14.6 million of non-cash collateralized letters of credit mentioned above, there were outstanding under the facility at June 30, 2010, $12.6
million letters of credit which were collateralized by $13.2 million of cash. Based upon our available cash balances, we do not currently anticipate



33



---

using this facility except to obtain and maintain letters of credit. Additionally, we expect our fixed charge coverage ratio to be less than 1.1 to 1.0 at June 30, 2010 and throughout 2010,
and, accordingly to remain subject to the limitation on our ability to fully utilize our adjusted borrowing base capacity as described above. As a result, our ability to obtain and maintain non-cash collateralized letters of credit under this
facility will continue to be constrained to an amount that does not exceed the excess of our adjusted borrowing base over $50 million.

Subject to certain exceptions, obligations under the credit facility are secured by, among other things, a first-priority lien on our present and future
receivables, inventory and certain general intangibles, and by a second-priority lien on substantially all of our domestic property, plant and equipment, and are guaranteed by certain of our subsidiaries.

The credit facility contains customary covenants applicable to us and our subsidiaries, other than certain unrestricted subsidiaries, including certain
financial covenants as well as restrictions on, among other things, our ability to: incur debt; incur liens; declare or make distributions to our stockholders; make loans and investments; repay debt; enter into mergers, acquisitions and other
business combinations; form or acquire subsidiaries; amend or modify our governing documents; enter into hedging arrangements; engage in other businesses other than our business as currently conducted; and enter into transactions with affiliates.
The credit facility also contains customary events of default, the occurrence of which could result in the acceleration of our obligation to repay the indebtedness outstanding thereunder.

Obligations under the indenture governing our Senior Secured Notes due 2017 are, in general, secured by a first-priority lien on the collateral that
secures obligations under the credit facility on a second-priority basis, and by a second-priority lien on the collateral that secures obligations under the credit facility on a first-priority basis, subject to the terms of an intercreditor
agreement, and are guaranteed by the subsidiaries that guarantee obligations under the credit facility.

The indenture contains customary
covenants applicable to us and our subsidiaries, other than certain unrestricted subsidiaries, including restrictions on actions and activities that are restricted under the credit facility. The indenture also contains customary events of defaults,
the occurrence of which could result in acceleration of our obligations to repay the indebtedness outstanding thereunder.

OTHER LIQUIDITY MATTERS

As of June 30, 2010, we had $34.1 million ($96.8 million, par value) of principal invested in auction rate securities (ARS). The ARS held by us are
securities with long-term nominal maturities for which the interest rates were historically reset through a Dutch auction each month.

We
review our marketable securities routinely for other-than-temporary impairment. The primary factors LP uses to determine if an impairment charge must be recorded because a decline in value of the security is other than temporary include
(i) whether the fair value of the investment is significantly below its cost basis, (ii) the financial condition of the issuer of the security (including its credit rating), (iii) the length of time that the cost of the security has
exceeded its fair value and (iv) LPs intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value.

If uncertainties in the credit and capital markets continue, these markets deteriorate further or we experience any ratings downgrades on any investments
in our portfolio (including on ARS), we may incur additional impairments to our investment portfolio, which could negatively affect our financial condition, results of operations and cash flow.

POTENTIAL IMPAIRMENTS

We
continue to review several mills and investments for potential impairments. Management currently believes we have adequate support for the carrying value of each of these assets based upon the anticipated cash flows that result from our estimates of
future demand, pricing and production costs assuming certain levels of planned capital expenditures. As of June 30, 2010, the undiscounted cash flows for the facilities indefinitely curtailed support the conclusion that no impairment is
necessary for those facilities. However, should the markets for our products continue to remain at levels significantly below cycle average pricing or should we decide to invest capital in alternative projects, it is possible that we will be
required to record further impairment charges.



34



---

We also review from time to time possible dispositions of various assets in light of current and anticipated
economic and industry conditions, our strategic plan and other relevant factors. Because a determination to dispose of particular assets can require management to make assumptions regarding the transaction structure of the disposition and to
estimate the net sales proceeds, which may be less than previous estimates of undiscounted future net cash flows, we may be required to record impairment charges in connection with decisions to dispose of assets.



|Item 3. | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------

A portion of our outstanding debt bears interest at variable rates and accordingly is sensitive to changes in interest rates. Interest rate changes would
result in gains or losses in the market value of our debt portfolio due to differences in market interest rates and the rates at the inception of the debt agreements. Offsetting the variable rate debt are variable rate notes receivable from asset
sales. Based upon the balances in the variable rate notes receivable from asset sales and the variable rate debt at June 30, 2010, a 100 basis point interest change would impact pre-tax net income and cash flows by $0.4 million annually.

Our international operations have exposure to foreign currency rate risks, primarily due to fluctuations in the Canadian dollar, Brazilian
real and the Chilean peso. Although we have in the past entered into foreign exchange contracts associated with certain of our indebtedness and may continue to enter into foreign exchange contracts associated with major equipment purchases to manage
a portion of the foreign currency rate risk, we historically have not entered into material currency rate hedges with respect to our exposure from operations, although we may do so in the future.

Some of our products are sold as commodities and therefore sales prices fluctuate daily based on market factors over which we have
little or no control. The most significant commodity product we sell is OSB. Based upon an assumed annual production capacity (including our joint venture operation) of 4.9 billion square feet
(3/8
 basis) or 4.2 billion square feet (7/16
 basis), a $1 change in the annual average price on7/16 basis would change annual pre-tax profits by
approximately $4.2 million. Because of the decline in the housing market and related indefinitely curtailed facilities in our OSB business, expected volumes will be significantly below our capacity.

We historically have not entered into material commodity futures and swaps, although we may do so in the future.



|Item 4. | Controls and Procedures
|------- | -----------------------

Evaluation
of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer have carried out, as of June 30,
2010, with the participation of LPs management, an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act (the Act). Based upon this evaluation, the
Chief Executive Officer and Chief Financial Officer have concluded that LPs disclosure controls and procedures are effective to provide reasonable assurance that material information required to be disclosed by us in reports we file under the
Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that information required to be disclosed by us in the reports we file or submit under the Act is accumulated and communicated to
our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

There were no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that materially
affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION



|Item 1. | Legal Proceedings.
|------- | ------------------

The
description of certain legal and environmental matters involving LP set forth in Part I of this report under Note 15  Contingency Reserves is incorporated herein by reference.



|Item 1A. | Risk Factors.
|-------- | -------------

You should be aware that
the occurrence of any of the events described in this Risk Factors section and elsewhere in this report or in any other of our filings with the SEC could have a material adverse effect on our business, financial position, results of operations and
cash flows. In evaluating us, you should consider carefully, among other things, the risks described below and the matters described in About Forward-Looking Statements.

Cyclical industry conditions and commodity pricing have and may continue to adversely affect our financial condition and results of operations.
Our operating results reflect the general cyclical pattern of the building products industry. Demand for our products correlates to a significant degree to the level of residential construction activity in North America, which historically has been
characterized by significant cyclicality. This cyclicality is influenced by a number of factors, including the supply of new and existing homes on the market, of which existing homes are currently at above average levels, the level of unemployment,
which has been increasing in recent periods, longer-term interest rates, which in recent years have been at relatively low levels, the availability of mortgage financing, which has recently declined, and mortgage foreclosure rates, which are higher
than normal. A significant increase in longer-term interest rates, a prolonged decline in the availability of mortgage financing, or the occurrence of other events that reduce levels of residential construction activity could have a material adverse
effect on our financial condition, results of operations and cash flows. Our primary product, OSB, and a significant portion of our raw materials are globally traded commodity products. In addition, our products are subject to competition from
manufacturers worldwide. Historical prices for our products have been volatile, and we, like other participants in the building products industry, have limited influence over the timing and extent of price changes for our products. Product pricing
is significantly affected by the relationship between supply and demand in the building products industry. Product supply is influenced primarily by fluctuations in available manufacturing capacity. Demand is affected by the state of the economy in
general and a variety of other factors. The level of new residential construction activity and home repair and remodeling activity primarily affects the demand for our building products. Demand is also subject to fluctuations due to changes in
economic conditions, interest rates, population growth, weather conditions and other factors. We are not able to predict with certainty market conditions and selling prices for our products. In this competitive environment with so many variables for
which we do not control, we cannot assure you that prices for our products will not decline from current levels. A prolonged and severe weakness in the markets for one or more of our principal products, particularly OSB, could seriously harm our
financial condition and results of operations and our ability to satisfy our cash requirements, including the payment of interest and principal on our debt.

We have a high degree of product concentration. OSB accounted for about 53% of our North American sales in the first six months of 2010 and 42% of
our North American sales in the first six months of 2009 and we expect OSB sales to continue to account for a substantial portion of our revenues and profits in the future. Concentration of our business in the OSB market further increases our
sensitivity to commodity pricing and price volatility. In this competitive environment with so many variables for which we do not control, we cannot assure you that pricing for OSB or our other products will not decline from current levels.

Intense competition in the building products industry could prevent us from increasing or sustaining our net sales and profitability.
The markets for our products are highly competitive. Our competitors range from very large, fully integrated forest and building products firms to smaller firms that may manufacture only one or a few types of products. We also compete less directly
with firms that manufacture substitutes for wood building products. Many of our competitors have greater financial and other resources than we do, and certain of the mills operated by our competitors may be lower-cost producers than the mills
operated by us.

Our results of operations may be harmed by potential shortages of raw materials and increases in raw material costs.
The most significant raw material used in our operations is wood fiber. We currently obtain about 79% of our



37



---

wood fiber requirements in the open market. Wood fiber is subject to commodity pricing, which fluctuates on the basis of market factors over which we have no control. In addition, the cost of
various types of wood fiber that we purchase in the market has at times fluctuated greatly because of governmental, economic or industry conditions, and may be affected by increased demand resulting from initiatives to increase the use of biomass
materials in the production of heat, power, biobased products and biofuels. In addition to wood fiber, we also use a significant quantity of various resins in our manufacturing processes. Resin product costs are influenced by changes in the prices
or availability of raw materials used to produce resins, primarily petroleum products, as well as demand for and availability of resin products. Selling prices of our products have not always increased in response to raw material cost increases. We
are unable to determine to what extent, if any, we will be able to pass any future raw material cost increases through to our customers through product price increases. Our inability to pass increased costs through to our customers could have a
material adverse effect on our financial condition, results of operations and cash flows.

Many of the Canadian forestlands also are subject
to the constitutionally protected treaty or common-law rights of the aboriginal peoples of Canada. Most of British Columbia is not covered by treaties and, as a result, the claims of British Columbias aboriginal peoples relating to forest
resources are largely unresolved, although many aboriginal groups are actively engaged in treaty discussions with the governments of British Columbia and Canada. Final or interim resolution of claims brought by aboriginal groups are expected to
result in additional restrictions on the sale or harvest of timber and may increase operating costs and affect timber supply and prices in Canada. It is possible that, over the long term, such claims could have an adverse effect on our business,
financial condition and results of operations.

Our operations require substantial capital. Capital expenditures for expansion or
replacement of existing facilities or equipment or to comply with future changes in environmental laws and regulations may be substantial. Although we maintain our production equipment with regular periodic and scheduled maintenance, we cannot
assure you that key pieces of equipment in our various production processes will not need to be repaired or replaced or that we will not incur significant additional costs associated with environmental compliance. The costs of repairing or replacing
such equipment and the associated downtime of the affected production line could have a material adverse effect on our financial condition, results of operations and cash flow. If for any reason we are unable to provide for our operating needs,
capital expenditures and other cash requirements on economic terms, we could experience a material adverse effect on our business, financial condition, results of operations and cash flows.

We are subject to significant environmental regulation and environmental compliance expenditures and liabilities. Our businesses are subject to
many environmental laws and regulations, particularly with respect to discharges of pollutants and other emissions on or into land, water and air, and the disposal and remediation of hazardous substances or other contaminants and the restoration and
reforestation of timberlands. Compliance with these laws and regulations is a significant factor in our business. We have incurred and expect to continue to incur significant expenditures to comply with applicable environmental laws and regulations.
Moreover, some or all of the environmental laws and regulations to which we are subject could become more stringent in the future. Our failure to comply with applicable environmental laws and regulations and permit requirements could result in civil
or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing operations or requiring corrective measures, installation of pollution control equipment or remedial actions.

Some environmental laws and regulations impose liability and responsibility on present and former owners, operators or users of facilities and sites for
contamination at such facilities and sites without regard to causation or knowledge of contamination. In addition, we occasionally evaluate various alternatives with respect to our facilities, including possible dispositions or closures.
Investigations undertaken in connection with these activities may lead to discoveries of contamination that must be remediated, and closures of facilities may trigger compliance requirements that are not applicable to operating facilities.
Consequently, we cannot assure you that existing or future circumstances or developments with respect to contamination will not require significant expenditures by us.

We are involved in various environmental matters, product liability and other legal proceedings. The outcome of these matters and proceedings and the
magnitude of related costs and liabilities are subject to uncertainties. The conduct of our business involves the use of hazardous substances and the generation of contaminants and pollutants. In addition, the end-users of many of our products
are members of the general public. We currently are and from time to time in the future will be involved in a number of environmental matters and legal proceedings, including legal proceedings involving anti-trust, warranty or non-warranty product
liability claims, negligence and other



38



---

claims, including claims for wrongful death, personal injury and property damage alleged to have arisen out of the use by others of our or our predecessors products or the release by us or
our predecessors of hazardous substances. Environmental matters and legal matters and proceedings, including class action settlements relating to certain of our products, have in the past caused and in the future may cause us to incur substantial
costs. We have established contingency reserves in our consolidated financial statements with respect to the estimated costs of existing environmental matters and legal proceedings to the extent that our management has determined that such costs are
both probable and reasonably estimable as to amount. However, such reserves are based upon various estimates and assumptions relating to future events and circumstances, all of which are subject to inherent uncertainties. We regularly monitor our
estimated exposure to environmental and litigation loss contingencies and, as additional information becomes known, may change our estimates significantly. However, no estimate of the range of any such change can be made at this time. We may incur
costs in respect of existing and future environmental matters and legal proceedings as to which no contingency reserves have been established. We cannot assure you that we will have sufficient resources available to satisfy the related costs and
expenses associated with these matters and proceedings.

The valuation of our investment in auction-rate securities (ARS) is subject to
uncertainties that are difficult to predict. With the liquidity issues experienced in global credit and capital markets, the ARS held by us have experienced multiple failed auctions as the amount of securities submitted for sale has exceeded the
amount of purchase orders. Given the failed auctions, the values of our ARS have been adversely affected. Factors that may further impact the valuation of our ARS include changes to credit ratings of the securities as well as to the underlying
assets supporting those securities, rates of default of the underlying assets, underlying collateral value, discount rates, counterparty risk and ongoing strength and quality of market credit and liquidity. If uncertainties in the credit and capital
markets continue, these markets deteriorate further or we experience additional ratings downgrades on any investments in our portfolio (including our ARS), we may incur additional impairments to our investment portfolio, which could negatively
affect our financial condition, results of operations and cash flows.

Settlements of tax exposures may exceed the amounts we have
established for known estimated tax exposures. We maintain reserves for known estimated tax exposures in federal, state and international jurisdictions and uncertain tax positions. Significant income tax exposures may include potential
challenges to intercompany pricing, the treatment of financing, acquisition and disposition transactions, the use of hybrid entities and other matters. These exposures are settled primarily through the closure of audits with the taxing jurisdictions
and, on occasion, through the judicial process, either of which may produce a result inconsistent with past estimates. We believe that we have established appropriate reserves for estimated exposures; however, if actual results differ materially
from our estimates we could experience a material adverse effect on our financial condition, results of operations and cash flows.

Fluctuations in foreign currency exchange rates could result in currency exchange losses. A significant portion of our operations are conducted
through foreign subsidiaries. The functional currency for our Canadian subsidiary is the U.S. dollar. The financial statements of this foreign subsidiary are remeasured into U.S. dollars using the historical exchange rate for property, plant and
equipment, timber and timberlands, goodwill, equity and certain other non-monetary assets and liabilities and related depreciation and amortization on these assets and liabilities. These transaction gains or losses are recorded in foreign exchange
gains (losses) in the income statement. The functional currency of our Chilean subsidiary is the Chileanpeso and the functional currency in our Brazil subsidiary is the Brazilianreal. Translation adjustments, which are based upon the
exchange rate at the balance sheet date for assets and liabilities and the weighted average rate for the income statement, are recorded in the Accumulated Comprehensive Income (Loss) section of Stockholders Equity. Therefore, a strengthening
of the Canadian dollar, the Chileanpeso or the Brazilianreal relative to the U.S. dollar may have a material adverse effect on our financial condition and results of operations.

Our ability to service our indebtedness, to refinance our indebtedness or to fund our other liquidity needs is subject to various risks. Our
ability to make scheduled payments on and to refinance our indebtedness depends on and is subject to our financial and operating performance, which in turn is affected by general and regional economic, financial, competitive, business and other
factors, including the availability of financing in the banking and capital markets as well as the other risks described herein. In particular, demand for our products correlates to a significant degree to the level of residential construction
activity in North America, which historically has been characterized by significant cyclicality. According to the U.S. Census Bureau, single-family and multi-family housing starts for



39



---

the first six months of 2010 were approximately 14% higher than the same period in 2009. However, housing starts remained below normal levels. This reduced level of building was
caused, in part, by an increase in the inventory of homes for sale, a more restrictive mortgage market and a slowing economy. Although home building activity has improved in recent months, there can be no assurance that such improvement will
continue at recent rates or at all. We have experienced significant losses from operations and significant net cash used in operating activities in recent periods, and any further improvement in our operating performance is subject to continuing
improvement in the factors referred to above. Accordingly, we cannot assure you that our business will generate sufficient cash flows from operations or that future borrowings will be available to us in an amount sufficient to enable us to service
our debt, to refinance our debt or to fund our other liquidity needs. If we are unable to service our debt obligations or to fund our other liquidity needs, we could be forced to curtail our operations, reorganize our capital structure or liquidate
some or all of our assets in a manner that could cause the holders of our securities to experience a partial or total loss of their investment in us.

We have not independently verified the results of third-party research or confirmed assumptions or judgments upon which it may be based, and the
forecasted and other forward-looking information contained therein is subject to inherent uncertainties. We refer in this report and other documents that we file with the SEC to historical, forecasted and other forward-looking information
published by sources such asRISI,Random Lengths and the U.S. Census Bureau that we believe to be reliable. However, we have not independently verified this information and, with respect to the forecasted and forward-looking
information, have not independently confirmed the assumptions and judgments upon which it is based. Forecasted and other forward looking information is necessarily based on assumptions regarding future occurrences, events, conditions and
circumstances and subjective judgments relating to various matters, and is subject to inherent uncertainties. Actual results may differ materially from the results expressed or implied by, or based upon, such forecasted and forward-looking
information.
