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 11) 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 minority
interest. 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, 2007.

NOTE 2  STOCK-BASED COMPENSATION

For the quarters
ended September 30, 2008 and 2007, the total compensation expense related to LPs stock-based compensation plans was $2.5 million and $1.9 million. For the nine months ended September 30, 2008 and 2007, the total compensation expense
related to LPs stock-based compensation plans was $7.4 million and $5.2 million. At September 30, 2008, 2,634,084 shares were available under the current stock-based plans for stock-based awards. For the nine months ended
September 30, 2008, the fair value of the options granted was estimated using the Black-Sholes option-pricing model with the following weighted-average assumptions: a risk free interest rate of 2.97%; an expected volatility factor for the
market price of the Companys common stock of 30.2% (based upon historical volatility over the expected life of the options); a dividend yield of 4.0%; and an expected life of 5 years (based upon historical experience of the options). For
the nine months ended September 30, 2007, the fair value of the options granted was estimated using the Black-Sholes option-pricing model with the following weighted-average assumptions: a risk free interest rate of 4.84%; an expected volatility
factor for the market price of the Companys common stock of 29.8% (based upon historical volatility over the expected life of the options); a dividend yield of 2.6%; and an expected life of 4 years (based upon historical experience of the
options). The weighted-average fair value of options and stock settled stock appreciation rights (SSARs) granted during the nine months ended September 30, 2008 and September 30, 2007 was $2.85 and $5.55.

As of September 30, 2008, LP had $39.7 million ($151.8 million, par value) of principal invested in auction
rate securities (ARS). The ARS held by LP are securities with long-term nominal maturities for which the interest rates are reset through a dutch auction each month. These auctions historically have provided a liquid market for these securities.
LPs investments in ARS represent interests in collateralized debt obligations supported by pools of residential and commercial mortgages, credit linked notes and bank trust preferred notes.

Consistent with the companys investment policy guidelines, the ARS investments held by the company all had AAA or equivalent credit ratings (except for one
corporate ARS rated AA) at the time of purchase. With the liquidity issues experienced in global credit and capital markets, the ARS held by LP at September 30, 2008 have experienced multiple failed auctions as the amount of securities
submitted for sale has exceeded the amount of purchase orders. As of September 30, 2008 and November 6, 2008, all LPs ARS securities continue to pay interest according to their stated terms. With the exception of two investments, all
investments maintain their original credit rating from Standard and Poors; however both Moodys Investor Service and Fitch Ratings downgraded these investments multiple times.

The estimated market value of the companys ARS holdings at September 30, 2008 was $39.7 million, which reflects a $112.1 million adjustment to the par value of $151.8 million. Based upon LPs
evaluation of the structure of LPs ARS holdings and current market estimates of fair value from issuing banks, LP has recorded an other-than-temporary impairment of $88.7 million ($54.4 million after tax) in the third quarter of 2008 and $91.2
million ($55.9 million after tax) for the nine month period ended September 30, 2008 that was recorded as non-operating income (expense). The expense recorded in the third quarter of 2008 reflects the additional decline in value $31.8 million
($19.5 million after tax) as well as the reclassification of $56.9 million ($34.9 million after tax) of unrealized losses previously recorded in other comprehensive income as a reduction in shareholders equity.

LP reviews its marketable securities routinely for other-than-temporary impairment. The primary factors LP used 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.

NOTE 4  FAIR VALUE MEASUREMENTS

Effective January 1, 2008, LP adopted Statement of Financial Accounting Standards (SFAS) No. 157, Fair Value Measurements (SFAS 157), for financial assets and liabilities and any other
assets and liabilities carried at fair value. This pronouncement defines fair value (FV), provides guidance on how to measure FV under generally accepted accounting principles, and expands FV measurement disclosures. LPs adoption of SFAS 157
did not have a material impact on its consolidated financial position and results of operations.

SFAS 157 defines FV as the exchange price that would
be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. SFAS 157 also
establishes a FV hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Under this standard, LP is required to classify these financial assets and
liabilities into two groups: recurring  measured on a periodic basis and non-recurring  measured on an as needed basis.

SFAS 157
describes three levels of inputs that may be used to measure fair value:



|        |  |                                                                                                                                                                                                                                                                                 
|------- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1 |  | Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.                                                                                                                                       
|        | 
|Level 2 |  | Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; or valuations based on models where the
significant inputs are observable or can be corroborated by observable market data.
|        | 
|Level 3 |  | Valuations based on models where significant inputs are not observable. Unobservable inputs are used when little or no market data is available and reflect the Companys own assumptions
about the assumptions market participants would use.                                  

Assets measured at fair value on a recurring basis are summarized in the following table.



|                              |  |                   |       |                                                            |   |                                           |  |                                        |       |  |   |

Available for sale securities measured at fair value are recorded in cash and cash equivalents, short-term
investments, long-term investments and restricted cash on LPs condensed consolidated balance sheets. Included in available for sale securities are money market funds, U.S. government agency securities, commercial paper, corporate debt
obligations and auction rate securities.

Money market funds are valued at quoted market price from broker or dealer quotations or transparent pricing
sources at the reporting date, which represent Level 1 inputs. Government agency securities, commercial paper and corporate obligations are determined by evaluations based on observable market information from broker or dealer quotations, which
represent Level 2 inputs.

Due to the lack of observable market quotes on LPs auction rate securities (ARS) portfolio, LP evaluates the structure of
its ARS holdings and current market estimates of fair value, including fair value estimates from issuing banks that rely exclusively 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



11

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 and
grantor trust financial assets which are recorded in other assets in LPs condensed 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 quotes, which represent Level 1 inputs.

The grantor trust provides funds for benefits payable
under LPs Supplemental Executive Retirement Plan (SERP), an unfunded, non-qualified defined benefit plan that provides supplemental retirement benefits to key executives. The assets of the grantor trust, which are the cash surrender value of
corporate-owned life insurance, are invested in index funds which are reported at fair value based on the underlying share prices provided by the third party insurance carrier, which represent Level 3 inputs.

Derivatives are valued using quoted forward foreign exchange prices or quoted commodity index prices, depending upon the derivative, at the reported date, which
represents Level 2 inputs.

The following table summarizes assets measured at fair value on a recurring basis using significant unobservable inputs (Level
3) during the period.

NOTE 5  EARNINGS PER SHARE

Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares and
dilutive potential common shares outstanding during the period. Dilutive potential common shares primarily consist of employee stock options, stock settled stock appreciation rights (SSARs), restricted stock units and restricted common stock.

SFAS No. 128, Earnings per Share, requires that employee equity share options, non-vested shares and similar equity instruments granted
by the Company be treated as potential common shares outstanding in computing diluted earnings per share. Diluted shares outstanding include the dilutive effect of in-the-money options, which is calculated, based on the average share price for each
fiscal period using the treasury stock method. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount
of tax benefits that would be recorded in additional paid-in capital when the award becomes deductible are assumed to be used to repurchase shares.

NOTE 9  BUSINESS ACQUIRED

In May 2008, LP completed the initial phase of its purchase of a 75% ownership interest in Masisa OSB Industria e Comercio S.A., which operates OSB assets located in Ponta Grossa, Brazil. The purchase is being made through LP Brasil
Participacoes Ltda., a limited liability company, and a wholly-owned subsidiary of Louisiana-Pacific South America S.A., a wholly-owned subsidiary of LP. The minority ownership is subject to a put and call option that are exercisable three years
after the date of initial closing of the acquisition, is being accounted for as mandatory redeemable minority interest and will be accreted over the life of the put and call to the estimated price which is the greater of $18.5 million plus interest
or a multiple of earnings before interest and taxes (subject to certain adjustments). The purchase price was approximately $56.4 million (including expenses), of which $44.6 million was paid in cash at the time of initial closing and the remaining
amount (subject to closing date adjustments) was paid in early October. LP will take over operations in early November. As of September 30, 2008, the purchase price was allocated to tangible assets acquired based on their book value as of the
acquisition date with the remaining value allocated to goodwill. LP is obtaining an appraisal of the tangible and intangible assets and expects this allocation to be revised in the fourth quarter of 2008.

The following table summarizes the estimated fair values of the assets and liabilities acquired as of the acquisition date.

|NOTE 10  INCOME TAXES  Accounting standards require that income tax expense for interim periods 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 any changes in reserve requirements or statutory tax rate changes, if any. Each

These investments do not meet the Regulation S-X significance test requiring the inclusion of the separate investee
financial statements or summarized financial information.

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
September 30, 2008 and 2007, LP sold $3.4 million and $3.7 million of products to AbitibiBowater-LP and purchased $14.8 million and $18.0 million of I-joist from AbitibiBowater-LP. LP also purchased $24.8 million and $23.7 million of OSB from
Canfor-LP during the quarters ended September 30, 2008 and 2007. For the nine months ended September 30, 2008 and 2007, LP sold $7.3 million and $11.0 million of products to AbitibiBowater-LP and purchased $35.3 million and $54.9 million
of I-joist from AbitibiBowater-LP. LP also purchased $66.9 million and $60.5 million of OSB from Canfor-LP during the nine months ended September 30, 2008 and 2007.

NOTE 14  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, LP believes that any fines, penalties or other costs or losses resulting from these matters will not have a material adverse effect on our financial position, results of operations, cash flows or liquidity.

Siding Matters

On October 15, 2002, a jury returned a verdict
of $29.6 million against LP in a Minnesota State Court action entitled Lester Building Systems, a division of Butler Manufacturing Company, and Lesters of Minnesota, Inc., v. Louisiana-Pacific Corporation and Canton Lumber
Company. On December 13, 2002, the United States District Court for the District of Oregon, which maintains jurisdiction over a previously settled nationwide class action suit involving OSB siding manufactured by LP and installed prior to
January 1, 1996, permanently enjoined the Minnesota state trial court from entering judgment against LP with respect to $11.2 million of the verdict that related to siding that was subject to the nationwide OSB siding settlement. LP
satisfied this verdict, less the enjoined amount, during the second quarter of 2004. Lesters appealed the District Courts injunction to the Ninth Circuit Court of Appeals and, on October 24, 2005, the Court of Appeals vacated the
District Courts injunction. As a result of this decision, the injunction was lifted and the state court judgment of $11.2 million was entered on December 22, 2006. We timely filed our notice of appeal to the Minnesota State Court of
Appeals. On February 5, 2008, the Minnesota State Court of Appeals reversed the $11.2 million judgment entered against LP on December 22, 2006. Lesters timely appealed the Minnesota State Court of Appeals decision, and the
Minnesota State Supreme Court has granted review. Based upon the information currently available, LP believes that any further liability related to this case is remote and, accordingly, has not recorded any accrual with respect to its potential
exposure.

Lockhart Wood Treatment Facility

In 2004,
LP received a pre-litigation settlement demand letter from a law firm purporting to represent more than 1,400 potential plaintiffs who allegedly experienced various personal injuries and property damages as a result of the alleged release of
chemical substances from LPs wood treatment facility in Lockhart, Alabama during the period from 1953 to 1998. The letter was also addressed to Pactiv Corporation (Pactiv), from whom LP acquired the facility in 1983. LP, Pactiv,
and the potential plaintiffs agreed to exchange information and enter into non-binding mediation, which failed in December 2005. In the first quarter of 2006, plaintiffs attorneys filed 19 separate lawsuits on behalf of 1,429
plaintiffs. Each of these cases was filed in, or removed to, the United States District Court for the Middle District of Alabama, which court has designated a lead case under the caption Melanie Chambers v. Pactiv Corp et al, CV
2:06-CV-00083-LES-CSC. After extensive motion practice and the beginning

---

of discovery, Pactiv and plaintiffs have agreed to a tentative settlement. In addition, LP has agreed to a settlement pursuant to which LP would make a
payment of $7.75 million to resolve this matter on the terms of a full and final release of all claims by all plaintiffs. LP accrued the amount of this tentative settlement in the fourth quarter of 2007 and expects to make payment in the fourth
quarter of 2008.

Anti-trust Litigation

LP was named
as one of a number of defendants in multiple class action complaints filed on or after February 26, 2006 in the United States District Court for the Eastern District of Pennsylvania. These complaints were dismissed or consolidated into two
complaints under one caption: In Re OSB Anti-Trust Litigation, Master File No. 06-CV-00826 (PD). The first complaint is a consolidated amended class action complaint filed on March 31, 2006 on behalf of plaintiffs who directly
purchased OSB from the defendants from May 1, 2002 through the date the complaint was filed (the direct purchaser complaint). The second complaint is a consolidated amended class action complaint, filed on June 15, 2006, on behalf of
plaintiffs who indirectly purchased OSB from the defendants from May 1, 2002 through the date the complaint was filed (the indirect purchaser complaint).

The plaintiffs in both amended and consolidated complaints described above moved for and received class certification and sought treble damages totaling approximately $4.8 billion alleged to have resulted from a conspiracy among the
defendants to fix, raise, maintain and stabilize the prices at which OSB is sold in the United States, in violation of Section 1 of the Sherman Act, 15 U.S.C. §1. The plaintiffs in the indirect purchaser complaint also seek similar
remedies under individual state anti-trust and competition laws as well as consumer protection laws. LP believes that the claims asserted were without merit, but after being ordered to settlement conference by the judge in the cases, LP decided that
in order to limit the risks and costs associated with a prolonged trial schedule; it would settle the direct and indirect lawsuits. The settlement agreements are subject to court approval which is expected to occur in the fourth quarter of 2008. LP
accrued the settlement in the second quarter of 2008.

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 15  GOODWILL

Goodwill by operating segment is as follows:



|                              |  |     |       |        |   |       |  |       |      |  |   |      
|----------------------------- |  | --- | ----- | ------ | - | ----- |  | ----- | ---- |  | - | -----

|                              |  |     |       |        |   |       |  |       |      |  |   |      
|Balance at September 30, 2008 |  | $   | 232.5 |        | $ | 32.4  |  | $     | 13.5 |  | $ | 278.4
|                              |  |     |       |        |   |       |  |       |      |  |   |      

In connection with the acquisition described at note 9, LP recorded $4.9 million of goodwill. LP completes its
annual goodwill impairment analysis as of October 1, 2008. In testing for potential impairment, LP estimates the fair value of the reporting unit based upon its cash flow forecasts as compared to the book value of the respective reporting unit.
The key assumptions in estimating these cash flows include future production volumes and pricing of commodity products and future estimates of expenses to be incurred. LPs 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. As of September 30, 2008, based on the criteria in SFAS No. 142, Goodwill and Other Intangible Assets,
no analysis of LPs goodwill was required.

NOTE 17  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. However, should the markets for the relevant products continue to remain at
levels significantly below cycle average 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 18  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 relating to 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, 2007. During the second quarter of 2008, LP increased its reserves in connection with this class action settlement as a result of increased claims activity. The additional reserves reflect revised estimates of
undiscounted future claim payments and related administrative costs. LP believes that the reserve balance at September 30, 2008 will be adequate to cover future payments to claimants and related administrative costs. However, LP is
investigating the circumstances that gave rise to the increase in claims activity in order to better assess its potential future liability associated with such settlement agreement and may be required to further adjust its related reserves in the
fourth quarter.

The activity in the portion of LPs loss contingency reserves relating to hardboard siding contingencies for the first nine months of
2008 and 2007 are summarized in the following table.



|                                       |  |                    |      |   |                    |   |      |

Through September 30, 2008, LP recognized $7.8 million of pension expense for all of LPs defined benefit
plans. LP presently anticipates recognizing an additional $2.6 million of pension expense in the remainder of 2008 for a total of $10.4 million.

Through
September 30, 2008, LP made $0.9 million of pension contributions for all of LPs defined benefit plans. LP presently anticipates making approximately $0.4 million of additional pension contributions for the plans during the remainder of
2008 for a total of $1.3 million.

NOTE 20  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 20 of the Notes to the financial statements included in LPs Annual Report on Form 10-K for the year ended December 31, 2007 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 first nine months of 2008 and 2007 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.

During the third quarter of 2008, LP increased the warranty reserves relating to its discontinued composite decking products by $15.2 million resulting in total charges of $17.2 million for the nine month period ended September 30,
2008. The additional reserves reflect revised estimates of future claim payments based upon a significant increase in decking warranty claims related to a specific operation and specific time period. LP is currently investigating the causes of this
increase as well as reviewing other appropriate actions. LP believes that the warranty reserve balance at September 30, 2008 will be adequate to cover future warranty payments. However, it is possible that additional charges may be required in
the future.

NOTE 21 - RECENT AND PROSPECTIVE ACCOUNTING PRONOUNCEMENTS

In September 2006, the Financial Accounting Standard Board (FASB) finalized SFAS No. 157, Fair Value Measurements (SFAS 157). This Statement defines fair value, establishes a framework for measuring
fair value and expands disclosures about fair value measurements; however, it does not require any new fair value measurements. The provisions of SFAS 157 were applied prospectively to LPs fair value measurements and disclosures as of
January 1, 2008 with respect to recurring financial assets and liabilities and did not have a material effect on the companys Consolidated Financial Statements. The provisions of SFAS 157 related to LPs nonrecurring nonfinancial
assets and liabilities will be applied prospectively to fair value measurements and disclosures in the first quarter of 2009 and is not expected to have a material effect on the companys consolidated financial statements.



22



---

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial
Liabilities, Including an Amendment of FASB Statement No. 115, (SFAS 159). SFAS 159 permits entities to measure eligible financial assets, financial liabilities and firm commitments at fair value, on an instrument-by-instrument basis,
that are otherwise not permitted to be accounted for at fair value under other generally accepted accounting principles. The fair value measurement election is irrevocable and subsequent changes in fair value must be recorded in earnings. The
company adopted this Statement as of January 1, 2008 and it did not have a material effect on the companys consolidated financial statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements  an Amendment of Accounting Research Bulletin No. 51 (SFAS 160). SFAS 160 establishes accounting
and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 requires that noncontrolling interests in subsidiaries be reported in the equity section of the controlling
companys balance sheet. It also changes the manner in which the net income of the subsidiary is reported and disclosed in the controlling companys income statement. SFAS 160 is effective on a prospective basis for annual periods
beginning after December 15, 2008, except for the presentation and disclosure requirements which are to be applied retrospectively for all periods presented. LP is currently evaluating the impact of adopting SFAS 160 on its consolidated
financial statements.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations (SFAS 141(R)). SFAS 141(R)
addresses the recognition and accounting for identifiable assets acquired, liabilities assumed, and noncontrolling interests in business combinations. SFAS 141(R) also establishes expanded disclosure requirements for business combinations.
SFAS 141(R) is effective for annual periods beginning after December 15, 2008 and should be applied prospectively for all business combinations entered into after the date of adoption.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, an Amendment of FASB Statement
No. 133 (SFAS 161). SFAS 161 amends and expands the disclosure requirements of Statement 133 to provide a better understanding of how and why an entity uses derivative instruments, how derivative instruments and related hedged items are
accounted for, and their effect on an entitys financial position, financial performance, and cash flows. SFAS 161 is effective for fiscal years beginning after November 15, 2008. LP is currently evaluating the impact of adopting SFAS
161 on its consolidated financial statements.

In October 2008, the FASB issued Staff Position No. FAS 157-3, Determining the Fair Value of a
Financial Asset When the Market for That Asset is Not Active (FSP FAS 157-3). FSP FAS 157-3 amends SFAS 157 by incorporating an illustrative example on how to determine the fair value of a financial asset in an inactive market and clarifying
application issues associated with SFAS 157. FSP FAS 157-3 is effective as of October 10, 2008 and is applicable to prior periods for which financial statements have not yet been issued. The company adopted this Statement as of
September 30, 2008 and it did not have a material effect on the companys consolidated financial statements.

|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 for some of our specialty building products. Our manufacturing facilities are primarily located in the U.S. and Canada, but we also
operate two facilities in Chile and recently acquired an interest in a Brazilian facility.

To serve these markets, we operate in three segments: Oriented
Strand Board (OSB), Siding, and Engineered Wood Products (EWP). OSB is the most significant segment, accounting for about 44% of sales during the nine months ended September 30, 2008 and about 48% of sales in the nine months ended
September 30, 2007.

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. In the first nine months of 2008, the U.S. Department of Census reported that actual single and multi-family housing starts were about 31% lower than the first nine months of
2007. We believe that the reduced level of building is due to the increase in the inventory of homes for sale coupled with a much more restrictive mortgage market. Additionally, the reduction in home values and the large amount of variable rate
mortgages that are resetting has increased the number of foreclosures, which add to the stock of homes for sale. Building activity is unlikely to improve until the number of homes available for sale is reduced and the rate of purchases increases.

Our most significant product, 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, 2007 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, 2007 is a discussion of our significant accounting policies and significant accounting
estimates and judgments. The discussion of each of the policies and estimates outlines the specific accounting treatment related to each of these accounting areas.

Accounting Policies

There are several policies that we have adopted and implemented from among acceptable alternatives that could lead to
different financial results had another policy been chosen:

Inventory valuation.We use the LIFO (last-in, first-out) method for some of our log
inventories with the remaining inventories valued at FIFO (first-in, first-out) or average cost. Our inventories would have been approximately $3.2 million higher if the LIFO inventories were valued at average cost as of September 30, 2008.

Property, plant and equipment.We principally use the units of production method of depreciation for machinery and equipment. This method
amortizes the cost of machinery and equipment over the estimated units that will be produced during its estimated useful life.

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 2008, these significant accounting estimates and judgments include:

Auction Rate Securities: Auction-rate securities
represent interests in collateralized debt obligations, a portion of which are collateralized by pools of residential and commercial mortgages, interest-bearing corporate debt obligations, a dividend-yielding preferred stock or other instruments.
Liquidity for these auction-rate securities is typically provided by an auction process that resets the applicable interest rate at pre-determined intervals, usually every 7, 28, 35 or 90 days. Because of the short interest rate reset period,
we have historically recorded auction-rate securities in current available-for-sale securities. As of September 30, 2008, 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 $39.7 million ($151.8 million, par value) of auction-rate securities as long-term available-for-sale securities that were classified previously as short-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 issuing banks. During the nine months ended September 30, 2008, we recorded an other-than-temporary impairment of $91.2
million that was recorded as non-operating income (expense). This impairment includes the reversal of $31.5 million in cumulative unrealized losses associated with the temporary declines in value of our ARS holdings that were recorded net of tax in
accumulated other comprehensive income as of December 31, 2007. In accordance with EITF 03-1 and FSP FAS 115-1 and 124-1,The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments,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 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 September 30, 2008, we excluded from our estimates approximately $0.6 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. 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, on assets held and used, impairments are recognized when the book
values exceed our estimate of the undiscounted future net cash flows associated with the affected assets. The key assumptions in estimating these cash flows include future production volumes and pricing of commodity or specialty products and future
estimates of expenses to be incurred. 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. These prices are estimated from
information gathered from industry research firms, research reports published by investment analysts and other published forecasts. Our estimates of expenses are based upon our long-range internal planning models and our expectation that we will
continue to reduce product costs that will offset inflationary impacts.

When impairment is indicated, the book values of the assets to be held and used
are written down to their estimated fair value, which is generally based upon discounted future cash flows. Assets to be disposed of 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 September 30, 2008, we had established valuation
allowances against certain deferred tax assets, primarily related to foreign tax credit carryovers, state net operating loss and credit carryovers and foreign capital loss carryovers. We have not established valuation allowances against other
deferred tax assets based upon expected future taxable income and/or 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.

Goodwill. Goodwill and other intangible assets that are deemed to have an
indefinite life are no longer amortized. However, these indefinite life assets are tested for impairment on an annual basis, and otherwise when indicators of impairment are determined to exist, by applying a fair value based test. The process of
evaluating the potential impairment of goodwill is highly subjective and requires significant judgments at many points during the analysis. In testing for potential impairment, the estimated fair value of the reporting unit, as determined based upon
cash flow forecasts, is compared to the book value of the reporting unit. The key assumptions in estimating these cash flows include future production volumes and pricing of commodity products and future estimates of expenses to be incurred. 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. These prices are estimated from information gathered from industry research
firms, research reports published by investment analysts and other published forecasts. Our estimates of expenses are based upon our long-range internal planning models and our expectation that we will reduce product costs that will offset
inflationary impacts.

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, if any, are subject to substantial uncertainties. Consequently,
as additional information becomes known, we may change our estimates significantly.

Pension Plans. Most of our U.S. employees and some 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. See further discussion related to pension plans below under the heading Defined Benefit Pension Plans and in Note 13 of the Notes to the financial statements
included in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2007.

Workers Compensation.We are
self-insured for workers compensation in most U.S. states. 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.

RESULTS OF OPERATIONS

(Dollar amounts in tables in millions)

Our net loss for the third quarter of 2008 was $111 million, or $1.08 per diluted share, on sales of $390 million, compared to net loss for the third
quarter of 2007 of $68 million, or $0.65 per diluted share, on sales of $473 million. For the third quarter of 2008, loss from continuing operations was $100 million, or $0.98 per diluted share, compared to loss from continuing operations of $55
million, or $0.52 per diluted share, for the third quarter of 2007.

Our net loss for the nine months ended September 30, 2008 was $238 million, or
$2.32 per diluted share, on sales of $1.1 billion, compared to net loss for the nine months ended September 30, 2007 of $128 million, or $1.23 per diluted share, on sales of $1.3 billion. For the nine months ended September 30, 2008, loss
from continuing operations was $226 million, or $2.19 per diluted share, compared to loss from continuing operations of $106 million, or $1.02 per diluted share, for the nine months ended September 30, 2007.

Our results of operations for each of our segments are discussed below as well as for the other category, which comprises products that are not individually
significant.

Percent changes in average sales prices and unit shipments for the quarter and nine months ended September 30, 2008
compared to the quarter and nine months ended September 30, 2007 are as follows:



|              |  |                                             |   |  |                                                 |    |  |                          |   |  |               |

|Commodity OSB |  |                                             |   |  |                                                 |    |  |                          |   |  |               |   

OSB prices increased slightly for the third quarter and first nine months of 2008 as compared to the corresponding
periods of 2007. The weakened price as compared to cycle average pricing is due to dramatically lower housing demand coupled with increased industry capacity in OSB. The increase in selling price favorably impacted net sales and operating losses by
approximately $7 million for the quarter and $24 million for the first nine months as compared to the corresponding periods of 2007. As compared to the corresponding periods of 2007, the decline in sales volume was primarily due to the curtailment
of our Silsbee, TX operation in the fourth quarter of 2007 (which likely will not run in 2008 or 2009) as well as other production curtailments to balance supply and demand.

Compared to the third quarter of 2007 and the first nine months of 2007, the primary factors, along with the increased sales prices, for decreased operating losses were reduced sales volumes. While costs increased due
to higher prices for petroleum based products used in manufacturing and less absorption of fixed costs due to curtailed operations, we improved the overall financial results by curtailing certain operations.

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

For both the third quarter of 2008 and the nine month period ended September 30, 2008 compared to the
corresponding periods in 2007, sales volumes for our SmartSide siding remained relatively flat. Sales prices in our SmartSide siding product line for the quarter and nine month period ended September 30, 2008 as compared to the corresponding
periods of 2007 changed due to changes in product mix with specific product prices remaining generally constant. In our Canexel product line, sales volumes for the third quarter and nine month period of 2008 as compared the corresponding periods of
2007 declined due to higher than prior year volumes sold under our 2008 winter buy program which reduced the normal seasonal increases in the second and third quarters of 2008. Sales volumes were also impacted by weakening in the Canadian housing
market. Sales prices for our Canexel product line decreased in the third quarter and increased in the nine month period ended September 30, 2008 as compared to the same periods of last year due to the impact of the strengthening or weakening
Canadian dollar as a majority of these sales are made in Canada.

Overall, the decline in operating results for our siding segment for the third quarter of
2008 compared to the same period of 2007 was primarily due to losses on OSB sales and increased manufacturing costs at one of our siding mills resulting from technological changes in our manufacturing processes.

During the third quarter and first nine months of 2008 compared to the corresponding periods of 2007, we saw
reductions in sales volumes in both LVL and I-Joist. These declines are attributed to a slowdown in the housing market. Net average selling prices declined as we continued to see price pressure caused by lower demand. 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 mill, which primarily produces plywood as a by-product from the
LVL production process. During the third quarter and first nine months of 2008, this segment absorbed the start-up losses attributable to the Houlton, Maine LSL mill as we incurred expenses associated with the start-up but produced minimal saleable
product.

For the third quarter and first nine months of 2008 compared to the corresponding periods of 2007, the results of operations for EWP were lower
primarily due to lower sales volume which increased our conversion costs, reductions in sales prices and start up costs associated with our Houlton LSL mill. Additionally, we saw increases in raw materials costs for veneer while OSB and lumber cost
remained relatively consistent with the prior year.

For the third quarter and first nine months of 2008 compared to the corresponding periods of 2007, sales in our
moulding operations were lower due to reduced retail demand while our sales in South American operations increased as we continued to penetrate local South American markets and began producing at our second mill in Chile. Additionally, we saw a
significant increase in our export sales during the first and second quarters of 2008 as compared to the corresponding periods of the prior year as the weakened U.S. dollar has made U.S. products more competitive.

---

Overall, operating results associated with these activities were negatively impacted by the administrative costs
associated with the new mill start-up in Chile, lower sales prices due to competition from imported OSB and the effects on our U.S. Greenfiber joint venture of weakness in its contractor business and increased raw material costs.

GENERAL CORPORATE AND OTHER EXPENSE, NET

For the third quarter and first
nine months of 2008 compared to the corresponding periods of 2007, general corporate expenses increased slightly. 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. The increase in the third quarter and first nine months of 2008 as compared to the corresponding periods of 2007 resulted from higher sales and marketing costs as we have added additional
personnel in our efforts to increase market share and increased accruals for management incentive programs.

INTEREST EXPENSE AND INVESTMENT INCOME

Investment income in the third quarter and the first nine months of 2008 was significantly lower than in the corresponding periods of 2007 due to lower
cash balances as well as lower interest rates. Capitalized interest is lower due to the completion of our Clarke County OSB mill in the fourth quarter of 2007 and our LSL facility in the first quarter of 2008. Investment income was also impacted by
losses on our SERP of $1.2 million and $2.5 million for the third quarter and first nine months of 2008 as compared to income of $0.5 million and $1.2 million in the corresponding periods of the previous year. Components of investment income, net of
interest expense, are as follows:

DISCONTINUED OPERATIONS

Included in discontinued operations for the third quarter and first nine months of 2008 and 2007 are the results of the operations of mills that have been or are to be divested. At September 30, 2008, we had one remaining decking
facility classified as discontinued. For the third quarter and first nine months of 2008 and 2007, the loss on discontinued operations relates to our decking operations as well as residual losses from previously discontinued operations. During the
third quarter of 2008, we signed a non-binding letter of intent to sell our remaining decking facility in Selma, Alabama. This sale is expected to close in the fourth quarter. Based upon estimated sales price, no further impairment is required.

Included in the operating losses of discontinued operations for the third quarter of 2008 is an increase in our decking warranty reserves of $15.2 million
based upon significant increases in recent warranty claim activity. This charge is in addition to the $2.0 million increase recorded in the second quarter of 2008.

Included in the operating losses of discontinued operations for the third quarter of 2007 is an additional $7.5 million impairment charge on assets held for sale to reduce the carrying value of these assets to their estimated sales price
less selling costs. This charge is in addition to the $9.5 million recorded in the second quarter of 2007. Additionally, during the third quarter of 2007, we recorded a charge of $3.5 million associated with the loss on an executed take or pay
contract associated with our decking operations.

INCOME TAXES

Accounting
standards require that income tax expense or benefit for interim periods 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 any changes in reserve requirements or statutory tax rate changes, 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 nine months ended September 30, 2008, the primary differences between the U.S. statutory rate of 35% and the
effective rate applicable to our continuing operations relate to our foreign debt structure and state income taxes. For the nine months ended September 30, 2007, the primary differences between the U.S. statutory rate of 35% and the effective
rate applicable to our continuing operations relate to our foreign debt structure, state income taxes and the favorable resolution of an outstanding state tax contingency.

The components and associated estimated effective income tax rates applied to the quarter and nine month periods ended September 30, 2008 and 2007 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 and Brazil. Federal income tax examinations for the years through 2004 have been effectively settled and audits for 2005 and 2006 began in the fourth quarter of 2007.
We are subject to state and local income tax examinations for the tax years 2000 through 2006. Canadian returns have been audited through 1999 and Revenue Canada commenced an examination of the years 2002 through 2004 in the second quarter of 2007.

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. We account for all of these plans and provide aggregated disclosures about these plans in the Notes to our financial statements
as required by SFAS No. 158 Employers Accounting for Defined Benefit Pension and Other Postretirement Plans  an amendment of FASB Statements No. 87, 88, 106, and 132(R) (SFAS 158), the recognition and disclosure
requirements of which were adopted as of December 31, 2006. See Note 13 of the Notes to financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2007. We estimate that our net periodic pension cost
for 2008 will be approximately $10.4 million. If a curtailment or settlement does occur in 2008, this estimate may change significantly. We estimate that we will contribute approximately $1.3 million to our defined benefit pension plans in 2008. As
of September 30, 2008, we had contributed approximately $0.9 million to these plans. At December 31, 2007, we had $36.0 million of net actuarial loss and $5.2 million of prior service cost included in accumulated other comprehensive loss.
Of these amounts, we expect to recognize a net actuarial loss of $2.8 million and prior service cost of $1.2 million as components of net periodic pension cost in 2008, which will account for approximately 38% of our estimated 2008 net periodic
pension cost.

LEGAL AND ENVIRONMENTAL MATTERS

For a discussion of legal and environmental matters involving us and the potential impact thereof on our financial position, results of operations and cash flows, see Items 3, 7 and 8 in our Annual Report on Form 10-K
for the year ended December 31, 2007, Note 18 to the Notes to the financial statements contained therein and Item 1, Legal Proceedings, in Part II of this report.

HARDBOARD SIDING LITIGATION UPDATE

The following discussion updates should be read in conjunction with the discussion of
our hardboard siding litigation set forth in Note 18 of the Notes to financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2007 and notes 11 and 18 of the Notes to the financial statements contained
within this report.

Cumulative statistics under hardboard settlements are as follows:



|                          |  |                    |  |               |  |

The average payment amount for settled claims as of September 30, 2008, June 30, 2008 and
December 31, 2007 was $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.

ENVIRONMENTAL COMPLIANCE

The U.S. government
has recently modified its position with respect to the enacted regulations related to Maximum Achievable Control Technology (MACT). MACT regulations govern the manner in which we measure and control the emissions from our manufacturing facilities
into the air. As of September 30, 2008 we have completed the capital expenditures necessary to achieve compliance with these regulations.

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 or debt 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.

Our net use of cash in operating and other activities, the decline in marketability and value of our investments in ARS and the recent turmoil in the credit and
financial markets have adversely affected our principal sources of liquidity. At September 30, 2008, we have $154.7 million in cash and cash equivalents, $143.9 million of short term investments, and $460.2 million of other current assets. In
addition, we expect to receive in the next three months around $50 million of net proceeds from disposition of non-core assets and income tax refunds.

---

We have undertaken a number of initiatives to reduce our use of liquidity, including: the suspension of dividends on our
common stock; the curtailment of operations at our OSB mills in Clarke County, Alabama, Chambord, Quebec, Athens, Georgia and Silsbee, Texas; the taking of downtime at many of our other facilities in order to manage the levels of our inventories of
finished goods; and the continued pursuit of efficiency gains and cost reductions through Lean Sigma Six programs implemented throughout our organization.

As of the date of this report, we are actively considering other possible measures to enhance our overall liquidity, including possible financing and refinancing transactions. In light of the recent turmoil in the credit and financial
markets, however, there can be no assurance as to whether, when or the terms upon which any such transactions will be consummated. The following discussion provides further details of our liquidity and capital resources.

OPERATING ACTIVITIES

During the first nine months of 2008, we used $91
million of cash in operating activities compared to $5 million in the first nine months of 2007. The increase in cash used in operating activities in the first nine months of 2008 was primarily a result of increased operating losses as well as
payment of legal settlements.

INVESTING ACTIVITIES

During
the first nine months of 2008, we used approximately $22 million in investing activities. Capital expenditures in the first nine months were $88 million and related primarily to the costs associated with our LSL facility in Houlton, Maine and $45
million to purchase an interest in an OSB mill in Brazil. Additionally, we contributed $3 million to our joint ventures for working capital requirements. We also used approximately $216 million to purchase investments with maturities in excess of 90
days and received $287 million on the sale of these types of investments. We received $54 million in principal payments on our notes receivable from asset sales. Additionally, included in accounts payable is $6 million related to capital
expenditures that had not yet been paid as of September 30, 2008.

During the first nine months of 2007, we generated approximately $92 million of
cash from investing activities. Capital expenditures for the first nine months of 2007 were $221 million and related primarily to the costs associated with our OSB mill in Alabama and the LSL facility in Houlton, Maine that were under construction.
Additionally, we contributed $5 million to our joint venture with Canfor Corporation for working capital requirements. We also used approximately $2.2 billion to purchase investments with maturities in excess of 90 days and received $2.5 billion on
the sale of these types of investments. Additionally, included in accounts payable is $35 million related to capital expenditures that had not yet been paid as of September 30, 2007.

Capital expenditures for existing facilities and investments in existing joint ventures for 2008 are expected to total about $100 to $120 million. We are working with
our expected partner to create a joint venture to manufacture LVL in which we would obtain a 50% ownership interest. We currently are the sole purchaser of this facilitys production through an exclusive sales arrangement. Given current market
conditions, the timing of this approximate $35 million contribution is uncertain.

FINANCING ACTIVITIES

In the first nine months of 2008, net cash used in financing activities was $89 million. During the first nine months of 2008, we repaid (net of borrowings) $16 million
under a credit facility to support general operating requirements in our Canadian and Chilean locations. Additionally, we borrowed $12 million under a long term credit facility to fund our Chilean expansion. We also repaid $54 million of our limited
recourse notes payable. Additionally, in the first nine months of 2008, we paid cash dividends of $31 million.

In the first nine months of 2007, net cash
used by financing activities was $8 million. In the first nine months of 2007, we borrowed $37 million under a revolving credit facility to support general operating requirements in our Canadian locations and borrowed $17 million under a secured
long-term credit facility to fund our Chilean expansion. Additionally, in the first nine months of 2007, we paid cash dividends of $47 million and repurchased one million shares of stock at a cost of $18 million.

CREDIT FACILITIES

We have a
revolving line of credit, expiring in September 2009, which provides for a committed borrowing capacity of $150 million. Subject to the willingness of existing or new lenders under the credit facility to advance additional funds, we may
increase our borrowing capacity under the facility by up to an additional $100 million. Based upon recent financial performance, the facility requires us to cash collateralize outstanding borrowings and letters of credit. This facility requires
LP to pledge, as security for its reimbursement obligations under the facility, cash collateral in an amount equal to 105% of the face amount of the borrowings or letters of credit outstanding under the facility at any time. At September 30,
2008, we had no borrowings outstanding under the facility. Letters of credit issued and outstanding, which reduce our borrowing capacity, totaled approximately $33.3 million as of September 30, 2008 and were cash collateralized with $34.9
million.

We also have a $10 million (Canadian) line of revolving credit facility in Canada. Our ability to obtain letters of credit under this facility
ends in December 2008. Based upon recent financial performance, the facility requires us to cash collateralize outstanding borrowings and letters of credit. This facility requires LP to pledge, as security for its reimbursement obligations under the
facility, cash collateral in an amount equal to 105% of the face amount of the borrowings or letters of credit outstanding under the facility at any time. Letters of credit issued and outstanding totaled approximately $0.8 million as of
September 30, 2008 and were cash collateralized with $0.8 million.

We have a $100 million (Canadian or US) credit facility in Canada. The facility
allows us to finance general operating requirements. At September 30, 2008, we had $24.6 million outstanding under this facility. Amounts outstanding under the facility are due upon demand and are included in LPs Condensed Consolidated
Balance Sheet under the caption short-term notes payable.

Louisiana Pacific Chile SA (LP Chile) has a committed term credit facility with a
Chilean bank for up to $40 million. LP Chiles ability to draw from this facility ends in December 2008, with the final maturity in March 2015. The proceeds from the facility are being used to fund construction of an additional OSB plant in
Chile. At September 30, 2008, there was $37 million outstanding under this facility. Borrowings under the facility were secured. Additionally, LP Chile has an unsecured working capital facility with a Chilean bank for up to $3.5 million. This
facility matures in May 2009. At September 30, 2008, there was $2 million outstanding under this facility.

OTHER LIQUIDITY MATTERS

As of September 30, 2008, we had $39.7 million ($151.8 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 are reset through a dutch auction each month. These auctions historically have provided a liquid market for these securities. Our investments in ARS represent interests in collateralized
debt obligations supported by pools of residential and commercial mortgages, credit linked notes and bank trust preferred notes.

Consistent with our
investment policy guidelines, the ARS investments held by us all had AAA or equivalent credit ratings (except for one corporate ARS rated AA) at the time of purchase. With the liquidity issues experienced in global credit and capital markets, the
ARS held by us at September 30, 2008 have experienced multiple failed auctions as the amount of securities submitted for sale has exceeded the amount of purchase orders. As of September 30, 2008 and November 6, 2008, all LPs ARS
securities continue to pay interest according to their stated terms. With the exception of two investments, all investments maintain their original credit rating from Standard and Poors; however both Moodys Investor Service and Fitch
Ratings downgraded these investments multiple times. The below table provides additional detail as to the composition of our auction rate securities as well as the year of issue.

The estimated market value of our ARS holdings at September 30, 2008 was $39.7 million, which reflects a $112.1
million adjustment to the par value of $151.8 million. Based upon our evaluation of the structure of our ARS holdings and current market estimates of fair value from issuing banks, we have recorded an other-than-temporary impairment of $88.7 million
($54.4 million after tax) in the third quarter of 2008 and $91.2 million ($55.9 million after tax) for the nine month period ended September 30, 2008 was recorded as non-operating income (expense). The expense recorded in the third quarter of
2008 reflects the additional decline in value $31.8 million ($19.5 million after tax) as well as the reclassification of $56.9 million ($34.9 million after tax) of unrealized losses previously recorded in other comprehensive income as a reduction in
shareholders equity.

Historically, given the liquidity created by the auctions, ARS were presented as current assets under marketable securities on
our balance sheet. Given the failed auctions, our ARS are illiquid until there is a successful auction for them. Accordingly, the entire amount of such remaining ARS has been reclassified from current to non-current assets on our balance sheet.

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.

The following details our debt ratings as of November 6, 2008:

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. 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.

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. Based upon our indebtedness at September 30, 2008, a 100 basis point interest rate change would impact the pre-tax net income and cash flow by $1.9 million annually.

Our international operations have exposure to foreign currency rate risks, primarily due to fluctuations in the Canadian dollar. Although we have in the
past entered into foreign exchange contracts associated with certain of our indebtedness and 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. Subsequent to September 30, 2008 to the date of this report, the US dollar strengthened significantly in relation to other
currencies in which we operate. Based on our current Canadian dollar denominated debt in our Canadian operation (functional currency is the US dollar) and the US denominated debt in our South American operations (functional currency is the local
currency), LP would report in the fourth quarter of 2008 a gain of $6.1 million (based upon rates in effect as of November 4, 2008) associated with these liabilities.

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 of 6.1 billion square feet (3/8 basis) or 5.2 billion square feet (7/16 basis), a $1 change in
the annual average price on 7/16 basis would change our annual pre-tax profits or losses by approximately $5.2 million.

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 September 30, 2008, 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 18  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 longer-term interest rates, which in recent years have been at relatively low levels, and the availability of mortgage financing, which has recently declined. A significant increase in longer-term interest rates, 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, the availability of mortgage financing, population growth, weather conditions and other factors. We
are not able to predict with certainty market conditions and selling prices for our products. 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 49% of our sales in 2007 and 55% of our sales in 2006 and we expect OSB
sales to continue to account for a substantial portion of our revenues and results of operations in the future. Concentration of our business in the OSB market further increases our sensitivity to commodity pricing and price volatility. 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 61% of our 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. 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



39



---

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, in the past, 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 and product liability and other legal proceedings
and subject to various product warranty claims. 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, the generation of contaminants and pollutants, and the sale of products and the making of product warranties. 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 and other 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 use or 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



40



---

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 known estimated exposures; however, if actual results differ materially from our estimates we
could experience a material adverse affect 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 Chilean pesoand the
functional currency in our Brazil subsidiary is the Brazilian real. 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 or further strengthening of the Canadian dollar, the Chilean pesoor the Brazilian realrelative to the U.S.
dollar may have a material adverse effect on our financial condition and results of operations.

We may be unable to service our indebtedness, to
refinance our indebtness or to fund our other liquidity needs.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 in the first nine months of 2008 were approximately 31% lower than in the first nine months of 2007. This reduced level of building has been caused, in part, by an increase in the inventory of homes for sale, a more restrictive mortgage
market and a slowing economy. Home building activity is unlikely to improve until the number of homes available for sale is reduced and the rate of home purchases increases. We have experienced significant losses from operations and significant net
cash used in operating activities in recent periods and expect to continue to experience such losses and net cash uses pending improvement in the factors referred to above. 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



41



---

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.

Execution of our business strategies could strain management and other resources, which could adversely affect our business and financial performance.Execution of our business strategies, particularly
those relating to international growth and the pursuit of strategic transactions, could place significant demands on our management, operational systems and capital and other resources, and could be disruptive to our relationships with suppliers,
distributors, customers and employees. If we are unable to effectively manage our growth, including business integration and other issues that may arise out of business combination transactions, our business, financial condition and results of
operations could be materially and adversely affected.
