NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

FOR THE QUARTERS ENDED MARCH 31, 2010 AND MARCH 31, 2009

NOTE 1: BASIS OF PRESENTATION

Our consolidated financial statements provide an overall view of our results and financial condition. They include our accounts and the accounts of entities that we control, including:

• majority-owned domestic and foreign subsidiaries and

• variable interest entities in which we are the primary beneficiary.

They do not include our intercompany transactions and accounts, which are eliminated.

We account for investments in and advances to unconsolidated equity affiliates using the equity method, with taxes provided on undistributed earnings. This means that we record earnings and accrue taxes in the period that the earnings are recognized by our unconsolidated equity affiliates.

We report our financial results and condition in two groups:

• Forest Products – our forest products-based operations, principally the growing and harvesting of timber, the manufacture, distribution and sale of forest products and corporate governance activities; and

• Real Estate – our real estate development and construction operations.

Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “we” and “our” refer to the consolidated company, including both Forest Products and Real Estate.

The accompanying unaudited Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. Except as otherwise disclosed in these Notes to Consolidated Financial Statements, such adjustments are of a normal, recurring nature. The Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements; as such certain disclosures normally provided in accordance with accounting principles generally accepted in the United States have been omitted. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2009.

RECLASSIFICATIONS

We have reclassified certain balances and results from the prior year for consistency with our 2010 reporting. This makes year-to-year comparisons easier. Our reclassifications had no effect on net earnings (loss) or Weyerhaeuser shareholders’ interest.

NOTE 2: ACCOUNTING PRONOUNCEMENTS

ACCOUNTING CHANGES WE IMPLEMENTED IN 2010

Variable Interest Entities (VIE)

In June 2009, the Financial Accounting Standards Board (FASB) issued guidance that amends existing consolidation guidance for VIEs by:

• changing the required approach for identifying the primary beneficiary of a VIE by replacing the quantitative-based risks and rewards calculation with a qualitative approach that focuses on identifying who has the power to direct activities that significantly affect an entity’s economic performance,

• requiring additional reconsideration events when determining whether an entity is a VIE to include loss of power from voting or similar rights to direct the activities that significantly affect the entity’s economic performance,

• requiring ongoing assessment of whether an enterprise is the primary beneficiary of a VIE and

• requiring additional disclosures over involvement with a VIE.

Our adoption of this guidance in first quarter 2010 did not have a material effect on our results of operations, financial position or cash flows.

Distributions to Shareholders with Components of Stock and Cash

The FASB issued guidance clarifying that the stock portion of a distribution to shareholders that allows them to elect to receive cash or stock with a limit on the amount of cash that will be distributed is considered a share issuance to be reflected in earnings per share prospectively.

Our adoption of this guidance did not affect our results of operations, financial position or cash flows. This guidance would apply to a distribution of earnings and profits to shareholders as part of a conversion to a real estate investment trust (REIT). See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Other Liquidity Related Disclosures” for more information regarding our conversion to a REIT.

NOTE 3: BUSINESS SEGMENTS

We are principally engaged in the growing and harvesting of timber; the manufacture, distribution and sale of forest products; and real estate development and construction. Our principal business segments are:

• Timberlands – which includes logs; timber; minerals, oil and gas; and international wood products;

• Wood Products – which includes softwood lumber, engineered lumber, structural panels, hardwood lumber and building materials distribution;

• Cellulose Fibers – which includes pulp, liquid packaging board and an equity interest in a newsprint joint venture;

• Real Estate – which includes real estate development, construction and sales; and

• Corporate and Other – which includes governance, corporate support activities and transportation. We also may record one-time gains or charges in the Corporate and Other segment related to dispositions or events that are not related to an individual operating segment.

6

An analysis and reconciliation of our business segment information to the respective information in the Consolidated Financial Statements is as follows:

	QUARTER ENDED
DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2010			MARCH 31, 2009
Sales to and revenues from unaffiliated customers:
Timberlands	$	202		$	157
Wood Products		604			542
Cellulose Fibers		410			364
Real Estate		151			172
Corporate and Other		52			40
		1,419			1,275
Intersegment sales:
Timberlands		171			171
Wood Products		16			18
Corporate and Other		4			3
		191			192
Total sales and revenues		1,610			1,467
Intersegment eliminations		(191	)		(192	)
Total	$	1,419		$	1,275
Net contribution to earnings:(1)
Timberlands	$	81		$	40
Wood Products		(19	)		(266	)
Cellulose Fibers		19			31
Real Estate		31			(96	)
Corporate and Other		12			(43	)
		124			(334	)
Interest expense		(112	)		(115	)
Less: capitalized interest		6			9
Income (loss) before income taxes		18			(440	)
Income tax benefit (expense)		(38	)		176
Net loss attributable to Weyerhaeuser common shareholders	$	(20	)	$	(264	)

(1) During first quarter 2010, we changed the methodology for allocating corporate costs to the business segments. The amounts presented for first quarter 2009 were not reclassified. Had 2009 been presented using the same methodology, net contribution to earnings would have decreased $4 million for Timberlands, $8 million for Wood Products, $4 million for Cellulose Fibers and $1 million for Real Estate, and increased by $17 million for Corporate and Other.

NOTE 4: NET EARNINGS (LOSS) PER SHARE

Our basic and diluted earnings (loss) per share attributable to Weyerhaeuser shareholders were:

• $(0.10) for the quarter ended March 31, 2010 and

• $(1.25) for the quarter ended March 31, 2009.

Basic earnings per share is net earnings divided by the weighted average number of our outstanding common shares.

Diluted earnings per share is net earnings divided by the sum of the:

• weighted average number of our outstanding common shares and

• the effect of our outstanding dilutive potential common shares.

Dilutive potential common shares may include:

• outstanding stock options,

• restricted stock units or

• performance share units.

We use the treasury stock method to calculate the effect of our outstanding dilutive potential common shares.

7

SHARES EXCLUDED FROM DILUTIVE EFFECT

The following shares were not included in the computation of diluted earnings (loss) per share for the quarters ended March 31, 2010, and March 31, 2009, due to our net loss position. However, some or all of these shares may be dilutive potential common shares in future periods.

Potential Shares Not Included in the Computation of Diluted Earnings (Loss) per Share

	QUARTER ENDED
SHARES IN THOUSANDS	MARCH 31, 2010	MARCH 31, 2009
Stock options	12,933	11,180
Restricted stock units	736	671
Performance share units	—	220

Share Repurchase Program

In December 2008, we announced a stock repurchase program under which we are authorized to repurchase up to $250 million of outstanding common shares. We repurchased a total of 66,691 shares of common stock for approximately $2 million under the program during first quarter 2009. All common stock purchases under the program were made in open-market transactions. We have not repurchased any more common shares since first quarter 2009.

NOTE 5: SHARE-BASED COMPENSATION

In first quarter 2010, we granted 1,264,337 stock options, 71,160 stock appreciation rights and 334,495 restricted stock units. In addition, 229,703 outstanding restricted stock unit awards vested during first quarter 2010. A total of 203,417 shares of common stock were issued as a result of restricted stock unit vesting and stock option exercises.

STOCK OPTIONS

Most of the stock options were granted with the following standard vesting and post-termination vesting terms:

• options vest ratably over 4 years;

• options granted prior to 2010 either vest or continue to vest in the event of death, disability, retirement or involuntary termination; and

• options granted in 2010:

• either vest or continue to vest in the event of death, disability, retirement at an age of at least 65 or age 62-64 with at least 10 years of service, or involuntary termination when the retirement criteria for full or continued vesting have been met;

• continue vesting for one year in the event of involuntary termination when the retirement criteria for full or continued vesting have not been met; and

• stop vesting for all other situations including early retirement prior to age 62 or at age 62-64 with fewer than 10 years of service.

The weighted average exercise price of all of the stock options granted in first quarter 2010 was $39.29.

Weighted Average Assumptions Used in Estimating the Value of Stock Options Granted in First Quarter 2010

	10-YEAR STANDARD OPTIONS
Expected volatility		37.62	%
Expected dividends		0.51	%
Expected term (in years)		5.16
Risk-free rate		2.52	%
Weighted average grant date fair value	$	14.01

STOCK APPRECIATION RIGHTS

Stock appreciation rights represent liability-classified awards that are remeasured to reflect the fair value at each reporting period. The following table shows the weighted average assumptions applied to all outstanding stock appreciation rights as of March 31, 2010.

Weighted Average Assumptions Used to Remeasure the Value of Stock Appreciation Rights as of March 31, 2010

	MARCH 31, 2010
Expected volatility		39.20	%
Expected dividends		0.44	%
Expected term (in years)		3.21
Risk-free rate		1.69	%
Weighted average fair value	$	9.47

RESTRICTED STOCK UNITS

The weighted average fair value of the restricted stock units granted in first quarter 2010 was $39.65. The post-termination vesting provisions for restricted stock units granted in 2010 were as follows:

• restricted stock units vest ratably over 4 years; and

• restricted stock units will be forfeited upon termination of employment for any reason, including retirement or involuntary termination.

We review the carrying value of our assets whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable through future operations. These events or changes in circumstances may include, but are not limited to:

• decisions made to curtail, close, sell or restructure operations;

• changes in the expected use of assets; and

• significant or prolonged adverse changes in financial markets and economic conditions in markets in which we operate.

Charges for Forest Products restructuring, closures and asset impairments for the quarters ended March 31, 2010, and March 31, 2009, include:

	QUARTER ENDED
DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2010			MARCH 31, 2009
Restructuring and closure charges:
Termination benefits	$	(1	)	$	66

Charges for restructuring and closures	$	—		$	82
Asset impairments:
Long-lived assets	$	1		$	11
Goodwill		—			3
Other assets		—			4
Impairment of goodwill and other assets	$	1		$	18

The charges recognized during first quarter 2009, are primarily related to the Wood Products closures and curtailments, corporate restructuring activities and additional costs recognized in connection with previously announced facility closures.

Asset impairment charges in 2009 include $9 million for software costs and $2 million related to a Wood Products distribution facility site. The fair value of the site was determined based on a broker’s quote classified as a Level 2 input in the fair value hierarchy. Goodwill impairment charges recognized in first quarter 2009 relate to goodwill in our hardwoods and industrial wood products reporting unit.

Changes in accrued termination benefits related to restructuring and facility closures during the quarter ended March 31, 2010, were as follows:

DOLLAR AMOUNTS IN MILLIONS
Accrued severance as of December 31, 2009	$	20
Payments		(9	)
Accrued severance as of March 31, 2010	$	11

The majority of the accrued severance balance as of March 31, 2010, is expected to be paid by the end of 2010.

NOTE 7: OTHER OPERATING COSTS (INCOME), NET

Other operating costs (income), net:

• exclude our Real Estate operations,

• include both recurring and occasional income and expense items and

• can fluctuate from year to year.

NOTE 8: REAL ESTATE ASSET IMPAIRMENTS AND OTHER RELATED CHARGES

We review homebuilding long-lived assets and investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. These assets are stated at cost unless events or circumstances trigger an impairment review. If a triggering event occurs and the asset’s carrying amount is not recoverable, we record an impairment loss, which is the difference between the asset’s book value and fair value. The determination of fair value is based on appraisals and market pricing of comparable assets when that information is available, or the discounted value of estimated future net cash flows from these assets.

During first quarter 2009, unfavorable market conditions caused us to re-evaluate our strategy to develop certain projects, reduce sales prices, increase customer incentives, or reassess the recoverability of our investments, which triggered impairment charges. Asset impairments are recorded as adjustments to the cost basis of inventory and investments.

Total Real Estate Impairment and Other Investment-Related Charges

	QUARTER ENDED
DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2010		MARCH 31, 2009
Real estate impairments	$	1	$	15

Other impairment related charges		—		3
Total impairments of long-lived assets and other related charges		1		42
Impairments of investments and other related charges		—		26
Total impairments and other related charges	$	1	$	68

The write-off of pre-acquisition costs primarily relates to forfeited deposits on options to purchase land. The first quarter 2009 charge represents the forfeiture of deposits on two projects that were planned for development of approximately 3,300 residential lots. As of March 31, 2010, we control approximately 63,000 lots under option.

Impairments of investments and other related charges relate to loans and investments in equity affiliates.

There may be individual homes or parcels of land that are held for sale within a community that is held for development. Impairment charges recognized as a result of adjusting individual held-for-sale assets within a community to estimated fair value less cost to sell are included in the total impairment charges below.

	Fair Value Measurements Using
DOLLAR AMOUNTS IN MILLIONS	Number of Projects Tested for Recoverability	Number of Projects Impaired	Impairment Charges Recognized		Fair Value of Impaired Projects		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
First Quarter 2010	12	2	$	1	$	7	$	5	$	2
First Quarter 2009	59	9	$	15	$	17	$	9	$	8

The significant unobservable inputs (Level 3) reported above are discounted future cash flows of the projects and investments. We use present value techniques based on discounting the estimated cash flows at a rate commensurate with the inherent risks associated with the assets and related estimated cash flow streams. Discount rates applied to the estimated future cash flows of our homebuilding assets in first quarter 2010 and 2009 were generally 18 percent.

In addition, the investments that were impaired in first quarter 2009 were written down to estimated fair values of zero based on Level 3 inputs.

NOTE 9: INVENTORIES

NOTE 11: FAIR VALUE OF FINANCIAL INSTRUMENTS

This note provides details about our:

• debt and

• other financial instruments.

FAIR VALUE OF DEBT

The fair value of our long-term debt was $5.9 billion as of March 31, 2010. The estimated fair values and carrying values consisted of the following:

	MARCH 31, 2010				DECEMBER 31, 2009
DOLLAR AMOUNTS IN MILLIONS	CARRYING VALUE		FAIR VALUE		CARRYING VALUE		FAIR VALUE
Financial Liabilities:
Long-term debt (including current maturities)
Forest Products	$	5,284	$	5,512	$	5,284	$	5,256
Real Estate	$	390	$	387	$	402	$	398

To estimate the fair value of long-term debt, we used the following valuation approaches:

• market approach – based on quoted market prices for the same types and issues of our debt; or

• income approach – based on the discounted value of the future cash flows using market yields for the same type and comparable issues of debt.

The inputs to the valuations are based on market data obtained from independent sources or information derived principally from observable market data.

The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at the measurement date.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

We believe that our other financial instruments, including cash, short-term investments, receivables, and payables, have net carrying values that approximate their fair values with only insignificant differences. This is primarily due to:

• the short-term nature of these instruments,

• carrying short-term investments at expected net realizable value and

• the allowance for doubtful accounts.

We also have long-term investments that are classified as available-for-sale securities. These securities’ carrying values approximate their fair values.

11

NOTE 12: PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

We recognized net pension credits of $8 million and other postretirement benefit costs of $7 million, for net credits of $1 million during first quarter 2010. This compares to net pension credits of $10 million and other postretirement benefit credits of $5 million, for total credits of $15 million during first quarter 2009. The components of net periodic benefit credits (costs) are:

Total net periodic benefit credits (costs)	$	8		$	10		$	(7	)	$	5

First quarter 2010 curtailment and special termination benefits are primarily related to the sale of Wood Products facilities announced in fourth quarter 2009.

FAIR VALUE OF PENSION PLAN ASSETS

As disclosed in our Annual Report on Form 10-K for the year ended December 31, 2009, the value reported for our pension plan assets at the end of 2009 was estimated. Additional information regarding the year-end values generally becomes available to us during the first half of the following year. We expect to complete the valuation of our pension plan assets during second quarter 2010. The final adjustments could affect net pension benefit (expense) depending on the magnitude of the adjustment.

RECEIVABLE FROM PENSION TRUST

In first quarter 2010, the pension trust repaid $50 million of the short-term loans made in 2008 and 2009, bringing the total receivable from the pension trust down to $96 million. The remaining $96 million balance was repaid in April 2010.

EXPECTED PENSION FUNDING

At the end of 2009, we reported that we intended to make a voluntary contribution of approximately $100 million to our U.S. qualified pension plans for the 2009 year by September 15, 2010. We contributed $100 million to our U.S. qualified pension plans in first quarter 2010. The contribution reduced 2009 taxable income, thereby increasing the amount of the 2009 operating loss refund that we received in first quarter 2010. The contribution also decreased the amount of earnings and profits that would have to be distributed in 2010 in order to convert to a real estate investment trust. The company estimates the required 2010 contribution could be as much as $20 million, which would be due by September 15, 2011.

MEDICARE PART D

We recorded a $28 million charge in first quarter 2010 as a result of the Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act. The charge is included in income tax benefit (provision) in our Consolidated Statement of Operations. We will no longer be able to claim an income tax deduction for prescription drug benefits provided to retirees and reimbursed under the Medicare Part D subsidy beginning in 2013. Accounting rules require the effect of the change to be recorded in the period that the law is enacted.

NOTE 13: COMPREHENSIVE INCOME (LOSS)

Our comprehensive income attributable to Weyerhaeuser common shareholders, net of tax, was $9 million for the quarter ended March 31, 2010.

NOTE 14: LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

This note provides details about our:

• legal proceedings and

• environmental matters.

LEGAL PROCEEDINGS

We are party to legal matters generally incidental to our business. The ultimate outcome of any legal proceeding:

• is subject to a great many variables and

• cannot be predicted with any degree of certainty.

However, whenever probable losses from litigation could reasonably be determined — we believe that we have established adequate reserves. In addition, we believe the ultimate outcome of the legal proceedings:

• could have a material adverse effect on our results of operations, cash flows or financial position in any given quarter or year; but

• will not have a material adverse effect on our long-term results of operations, cash flows or financial position.

ENVIRONMENTAL MATTERS

The issues we have concerning environmental matters are:

• site remediation and

• asbestos management.

Site Remediation

Under the Comprehensive Environmental Response Compensation and Liability Act – commonly known as the Superfund – and similar state laws, we:

• are a party to various proceedings related to the cleanup of hazardous waste sites and

• have been notified that we may be a potentially responsible party related to the cleanup of other hazardous waste sites for which proceedings have not yet been initiated.

Our Established Reserves. We have established reserves for estimated remediation costs on the active Superfund sites and other sites for which we are responsible.

Changes in the Reserve for Environmental Remediation

DOLLAR AMOUNTS IN MILLIONS
Reserve balance as of December 31, 2009	$	31
Reserve charges and adjustments, net		1
Payments		(3	)
Reserve balance as of March 31, 2010	$	29
Total active sites as of March 31, 2010		56

The changes in our reserves for remediation costs reflect:

• new information on any site concerning implementation of remediation alternatives,

• updates on prior cost estimates and new sites and

• costs incurred to remediate sites.

Estimates. We believe it is reasonably possible – based on currently available information and analysis – that remediation costs for all identified sites may exceed our reserves by up to $95 million. The increase in potential remediation costs of $65 million this quarter is due to the bankruptcy of a potentially responsible party with whom we are co-responsible for site remediation.

That estimate – in which those additional costs may be incurred over several years – is the upper end of the range of reasonably possible additional costs. The estimate:

• is much less certain than the estimates on which our accruals currently are based and

• uses assumptions that are less favorable to us among the range of reasonably possible outcomes.

13

In estimating our current accruals and the possible range of additional future costs, we:

• assumed we will not bear the entire cost of remediation of every site,

• took into account the ability of other potentially responsible parties to participate and

• considered each party’s financial condition and probable contribution on a per-site basis.

We have not recorded any amounts for potential recoveries from insurance carriers.

Asbestos Management

Some of our sites have asbestos containing materials. We have met our current legal obligation to identify and manage these materials. In situations where we cannot reasonably determine when asbestos containing materials might be removed from the sites, we have not recognized a liability because its fair value cannot be reasonably estimated.

NOTE 15: SUBSEQUENT EVENTS

At the annual meeting of shareholders on April 15, 2010, our shareholders approved amendments to the company’s articles of incorporation to increase the number of shares of common stock the company is authorized to issue up to 1.36 billion shares from 400 million shares and to impose ownership and transfer restrictions, which limit the number of shares any person or entity may own, including those attributed to it under the attribution provisions of the Internal Revenue Code, to no more than 9.8 percent of the aggregate value of the outstanding shares of any class or series of Weyerhaeuser equity shares. The amendments will be filed and become effective only if the company’s Directors elect to declare a dividend of the company’s accumulated earnings and profits (“Special Dividend”) so that Weyerhaeuser Company would be eligible to convert to a real estate investment trust. The Special Dividend, if declared, would be paid in a combination of stock and cash and is estimated to be approximately $5.5 billion to $5.7 billion. The board intends to cap the cash portion of the payout at 10 percent, or approximately $550 to $570 million, assuming a 2010 conversion. Shareholders also approved the issuance of up to 960 million shares of common stock to be used to pay out the Special Dividend, if declared.

EXPORTING ISSUES

We are a large exporter, affected by changes in:

• economic activity in Europe and Asia – especially Japan and China;

• currency exchange rates – particularly the relative value of the U.S. dollar to the Euro and the Canadian dollar; and

• restrictions on international trade or tariffs imposed on imports.

RESULTS OF OPERATIONS

In reviewing our results of operations, it is important to understand these terms:

• Price realizations refer to net selling prices – this includes selling price plus freight, minus normal sales deductions.

• Net contribution to earnings can be positive or negative and refers to:

• earnings (loss) before interest and income taxes for the Forest Products business segments; and

• earnings (loss) before income taxes for the Real Estate business segment. Interest that previously was capitalized to Real Estate assets that are sold is included in cost of products sold and is included in contribution to earnings for the Real Estate segment.

In the following discussion, unless otherwise noted, references to increases or decreases in income and expense items, price realizations, shipment volumes, and net contributions to earnings are based on the quarter ended March 31, 2010, compared to the quarter ended March 31, 2009. The periods are also referred to as 2010 and 2009.

Net loss attributable to Weyerhaeuser common shareholders per share, basic and diluted	$	(0.10	)	$	(1.25	)	$	1.15

Comparing 2010 with 2009

In 2010:

• Net sales and revenues increased $144 million – 11 percent.

• Net loss decreased $244 million – 92 percent.

Net sales and revenues

Net sales and revenues increased $144 million – 11 percent – primarily due to slight improvements in the U.S. homebuilding industry from historic lows and stronger pulp markets, which was reflected in the following:

• increased prices for residential building products – refer to the Wood Products segment discussion;

• increased price realizations and higher land sales and non-strategic dispositions – refer to the Timberlands segment discussion; and

• increased pulp sales realizations – refer to the Cellulose Fibers segment discussion.

The above increases were partially offset by a decrease in the number of single-family homes closed and in their average selling prices – refer to the Real Estate segment discussion.

Net loss attributable to Weyerhaeuser common shareholders

Our net loss was $244 million lower primarily due to the following:

• decreased restructuring, closure and asset impairment charges – refer to the Wood Products, Real Estate and Corporate and Other segment discussions;

• higher price realizations and gain on sale of assets – refer to the Wood Products segment discussion;

• decreased costs as a result of our cost reduction initiatives and portfolio changes – refer to the Wood Products, Real Estate, and Corporate and Other segment discussions;

• higher gross margins on single-family homes closed and gains on the sale of partnership interests – refer to the Real Estate segment discussion;

• increased domestic log prices in the West and higher contributions from land sales – refer to the Timberlands segment discussion; and

• increased pulp prices and volumes sold – refer to the Cellulose Fibers segment discussion.

16

These decreases in our loss were partially offset by the following:

• reduced income tax benefit primarily due to having earnings before tax this year compared to a loss in 2009,

• a tax charge related to the federal tax law change for Medicare Part D subsidies and

• increased maintenance and other operating costs - refer to the Cellulose Fibers segment discussion.

TIMBERLANDS

How We Did in First Quarter 2010

Here is a comparison of net sales and revenues to unaffiliated customers, intersegment sales, and net contribution to earnings for the quarters ended March 31, 2010, and March 31, 2009:

(1) Dispositions of higher and better use timberland and non-strategic timberlands are conducted through Forest Products subsidiaries.

(2) Includes logs, plywood and hardwood lumber harvested or produced by our international operations, primarily in South America.

Comparing 2010 with 2009

In 2010:

• Net sales and revenues to unaffiliated customers increased $45 million – 29 percent.

• Intersegment sales were flat.

• Net contribution to earnings increased $41 million – 103 percent.

Net sales and revenues – unaffiliated customers

The $45 million increase in net sales and revenues to unaffiliated customers resulted primarily from the following:

• Western log sales were flat as increased price realizations of 12 percent driven by stronger domestic markets were offset by an 11 percent decrease in log sales volumes.

• Canadian log sales volumes increased 195,000 cubic meters as a result of increased demand and price realizations increased 10 percent.

• We had more land exchanges, dispositions of non-strategic timberlands and sales of higher and better use lands in 2010.

• Products from our international operations increased primarily due to higher price realizations across all products.

The above items were partially offset by an 18 percent decrease in southern log sales volumes as a result of reduced harvest.

Intersegment sales

Intersegment sales remained flat as an increase in Canadian intersegment sales driven by increased demand was fully offset by a decrease in intersegment sales within the United States due to fewer Weyerhaeuser mills in operation as a result of closures and curtailments of several Wood Products operations in the United States during 2009.

17

Net contribution to earnings

The $41 million increase in net contribution to earnings consisted of:

• $26 million increase primarily due to higher domestic prices in the West, which offset lower export prices;

• $15 million in higher contributions from sales of higher and better use property and non-strategic timberland; and

• $12 million decrease in operating costs, which includes less salvage logging, less thinning and reduced spending on silviculture.

This was partially offset by a $9 million decrease as a result of a 15 percent reduction of harvest in the West and a 10 percent reduction of harvest in the South.

Our Outlook

Excluding the disposition of non-strategic timberlands, we expect second quarter operating earnings from the segment to be somewhat lower than first quarter, as higher log prices are offset by increased silviculture and road costs and lower fee timber harvest in the south.

Comparing 2010 with 2009

In 2010:

• Net sales and revenues increased $62 million – 11 percent.

• Net contribution to earnings improved $247 million – 93 percent.

Net sales and revenues

The lumber and oriented strand board markets were significantly affected by supply-related events in first quarter 2010. Production capacity that had been reduced by mill closures was hit with a sudden surge of orders, as customers restocked highly depleted inventories to accommodate an increase in housing starts. Though we are encouraged by the improvement in market conditions during the quarter, any lasting recovery must be supported by a sustained increase in core housing demand.

The $62 million increase in net sales and revenues was primarily due to the following:

• Structural lumber average price realizations increased 32 percent and shipment volumes decreased 14 percent.

• Engineered solid section average price realizations decreased 6 percent and shipment volumes increased 28 percent.

• Engineered I-joists average price realizations decreased 15 percent and shipment volumes increased 69 percent.

• Oriented strand board (OSB) average price realizations increased 26 percent and shipment volumes decreased 4 percent.

• Softwood plywood average price realizations decreased 3 percent and shipment volumes increased 18 percent.

Net contribution to earnings

The $247 million increase in net contribution to earnings was primarily due to the following:

• $70 million decrease in restructuring, closure and asset impairment charges;

• $58 million increase due to higher sales price realizations for structural lumber and OSB and increased sales volumes for engineered I-joists, engineered solid section and softwood plywood;

• $44 million net pretax gain on the sale of assets, including the sale of certain British Columbia forest licenses and associated rights and the sale of a sawmill;

• $28 million decrease in manufacturing costs due to increased operating efficiencies and lower warehousing and delivery costs;

• $22 million decrease in selling and administrative costs primarily due to previous cost reduction efforts; and

• $20 million decrease in litigation charges due to the settlement of Alder litigation in 2009.

Our Outlook

We expect the segment to be profitable in the second quarter. We anticipate improved operating rates, sales realizations and volumes, partially offset by higher log costs.

Net contribution to earnings	$	19	$	31	$	(12	)

Comparing 2010 with 2009

In 2010:

• Net sales and revenues increased $46 million – 13 percent.

• Net contribution to earnings decreased $12 million – 39 percent.

• On January 1, 2010, we exercised an option to acquire liquid packaging board extrusion equipment located at the Longview, Washington mill site. The acquisition will increase the mix of coated board sales and increase various costs, which will be partially offset by the elimination of extrusion service fees.

Net sales and revenues

Net sales and revenues increased $46 million, primarily due to the following:

• Pulp price realizations increased by $73 per ton – 11 percent – due to significant disruptions in available supply as a result of the Chilean earthquake and unseasonably wet weather in the southern U.S.

• Sales volumes for pulp increased 13,000 tons – 3 percent.

• Sales volumes for liquid packaging board increased 3,000 tons – 5 percent.

• Liquid packaging board price realizations increased by $30 per ton – 3 percent – due to a favorable mix shift to coated board sales partially offset by a decrease in market price.

Net contribution to earnings

Net contribution to earnings decreased $12 million, primarily due to the following:

• $37 million increase in maintenance and other operating costs, primarily due to timing of annual maintenance outages and the effect on Canadian operating costs of the weakening U.S. dollar compared to the Canadian dollar;

• $12 million increase in fiber and energy costs, related to higher prices for chips and fuel; and

• $8 million decrease in earnings from our newsprint joint venture.

Partially offsetting these decreases in earnings were the following:

• $31 million increase due to higher pulp price realizations and $2 million due to higher pulp sales volumes,

• $6 million improvement in liquid packaging board price realizations primarily due to improved coated board mix and

• $5 million decrease in chemical cost and extrusion fees reduced by consumption of extrusion resin.

Our Outlook

We expect second quarter earnings from the segment to improve significantly compared to first quarter. We anticipate higher pulp price realizations, partially offset by increased freight and slightly higher annual maintenance costs.

Single-family gross margin - excluding impairments (%)(1)	19.4	%	10.7	%	8.7	%

(1) Single-family gross margin equals revenue less cost of sales and period costs (other than impairments and deposit write-offs).

Comparing 2010 with 2009

In 2010:

• Net sales and revenues decreased $21 million – 12 percent.

• Net contribution to earnings increased $127 million.

Markets for new homes are highly differential across our operations with uneven demand patterns. Buyers in lower price points have been attracted by housing affordability, partially due to available tax credits and low mortgage rates. In certain regions, the market for new homes has experienced activity at higher price levels. Although the supply of new homes has stabilized, most of our markets have been affected by increasing levels of foreclosures and short-sales, high unemployment and low consumer confidence. We experienced improved market activity, as reflected in the following statistics:

• New orders for single-family homes sold increased 36 percent in first quarter 2010 compared to first quarter 2009.

• Contract cancellation rates in first quarter 2010 were 19 percent compared to 28 percent in first quarter 2009.

21

Net sales and revenues

The $21 million decrease in net sales and revenues resulted primarily from:

• Home closings decreased 8 percent to 393 in first quarter 2010 from 429 in first quarter 2009.

• Average selling prices of single-family homes decreased 3 percent to $365,000 in first quarter 2010 from $377,000 in first quarter 2009, primarily due to a change in mix.

• Revenues from land and lots sales decreased $2 million. Land and lots sales are a routine part of our home building and land development business, but they do not occur evenly throughout the year.

Net contribution to earnings

The $127 million increase in net contribution to earnings resulted primarily from:

• $72 million decrease in charges for impairments, pre-acquisition cost write-offs, and restructuring costs;

• $34 million increase in equity in income of equity affiliates – including gains of $33 million on the sale of interests in two commercial partnerships in first quarter 2010;

• $19 million decrease in selling, general and administrative costs – primarily due to lower volume of closings and overall cost reductions; and

• $8 million increase from single-family home closings, as lower per home construction costs and higher margins more than offset the effect of fewer closings and lower average sales prices.

Our Outlook

We expect second quarter results from single-family homebuilding operations to be comparable to the first quarter. We anticipate an increase in home sale closings, offset by lower average sales prices due to mix. We do not anticipate the significant level of earnings for the sale of commercial partnerships that we experienced in the first quarter.

CORPORATE AND OTHER

Our Corporate and Other segment includes:

• governance-related corporate support activities and company-wide initiatives, such as major system and infrastructure deployments; and

• transportation operations, including Westwood Shipping Lines and five short line railroads.

We also record certain gains or charges in the Corporate and Other segment related to dispositions or events that generally are not related to an individual operating segment.

How We Did in First Quarter 2010

Here is a comparison of net sales and revenues and net contribution to earnings for the quarters ended March 31, 2010, and March 31, 2009:

NET SALES AND REVENUES / NET CONTRIBUTIONS TO EARNINGS – CORPORATE AND OTHER

	QUARTER ENDED					AMOUNT OF CHANGE
DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2010		MARCH 31, 2009			2010 VS. 2009
Net sales and revenues	$	52	$	40		$	12
Net contribution to earnings	$	12	$	(43	)	$	55

Comparing 2010 with 2009

In 2010:

• Net sales and revenues increased $12 million – 30 percent.

• Net contributions to earnings increased $55 million.

Net sales and revenues

The $12 million increase in net sales and revenues primarily consisted of increased revenues generated by our Westwood shipping operations as a result of higher volumes and prices.

22

Net contribution to earnings

Net contribution to earnings increased $55 million, primarily due to the following:

• $20 million decrease in charges for corporate restructuring activities, primarily related to termination benefits;

• $16 million charge in first quarter 2009 for the market value of timberland property donated to the Weyerhaeuser Company Foundation;

• $15 million decrease in foreign exchange losses, primarily resulting from strengthening of the Canadian dollar relative to the U.S. dollar; and

• $9 million charge for asset impairments in first quarter 2009 with no comparable charge in 2010.

INTEREST EXPENSE

Including Real Estate, our interest expense incurred was:

• $112 million during first quarter 2010 and

• $115 million during first quarter 2009.

Interest expense incurred decreased $3 million, primarily due to reductions in our debt during third quarter 2009 offset slightly by net new debt issued in the fourth quarter of 2009.

INCOME TAXES

The 2010 income tax rate is higher than the statutory rate, primarily due to the effect of state and foreign income taxes on a low pre-tax earnings base. Additionally, income tax credits, which expired in 2009 and have not been extended, have not been included in the 2010 provision. Extension of the income tax credits would reduce the 2010 effective income tax rate.

Our effective income tax rates were:

• 42.3 percent for 2010 and

• 33.6 percent for 2009.

The 2010 rate excludes the effect of the following items:

• $28 million tax charge due to an inability to claim a tax deduction for prescription drug benefits provided to retirees and reimbursed under the Medicare Part D subsidy beginning in 2013.

• $3 million charge due to state tax law and rate changes.

The income tax rate for 2009 was lower primarily because foreign tax expense reduced the 2009 tax benefit and a provision for unrecognized tax benefits was recorded.

LIQUIDITY AND CAPITAL RESOURCES

We are committed to maintaining a sound and conservative capital structure which enables us to:

• protect the interests of our shareholders and lenders and

• have access at all times to all major financial markets.

Two important elements of our policy governing capital structure include:

• viewing the capital structure of Forest Products separately from that of Real Estate given the very different nature of their assets and business activity and

• minimizing liquidity risk by managing a combination of maturing short-term and long-term debt.

The amount of debt and equity for Forest Products and Real Estate will reflect the following:

• basic earnings capacity and

• liquidity characteristics of their respective assets.

CASH FROM OPERATIONS

Cash from operations includes:

• cash received from customers;

• cash paid to employees, suppliers and others;

• cash paid for interest on our debt; and

• cash paid for taxes.

Consolidated net cash (used in) provided by our operations in first quarter was:

• $190 million in 2010 and

• $(436) million in 2009.

23

Comparing 2010 with 2009

Net cash used in operations increased $626 million in 2010 as compared with first quarter 2009.

Net cash inflows related to income taxes increased $629 million for the quarter. We received income tax refunds of $576 million in first quarter 2010 for the carry back of the 2009 net operating loss and alternative fuel credits. We paid taxes of $53 million in first quarter 2009.

Cash received from customers, paid to employees and suppliers, and paid for interest did not change significantly first quarter 2010 compared to first quarter 2009.

CASH FROM INVESTING ACTIVITIES

Cash from investing activities includes:

• acquisitions of property, equipment, timberlands and reforestation;

• investments in or distribution from equity affiliates;

• proceeds from sale of assets and operations; and

• purchases and redemptions of short-term investments.

Summary of Capital Spending by Business Segment – Excluding Real Estate

We anticipate that our capital expenditures for 2010 – excluding acquisitions and our Real Estate business segment – will be approximately $200 million. However, that range could change due to:

• future economic conditions,

• weather and

• timing of equipment purchases.

Proceeds from the Sale of Nonstrategic Assets

Proceeds received from the sale of nonstrategic assets were $115 million in 2010. This included:

• $40 million for the sale of British Columbia forest licenses and associated rights,

• $33 million for the sale of partnership interests in our Real Estate Segment and

• $28 million for the sale of Wood Products assets.

In first quarter 2010, the pension trust repaid $50 million of the short-term loans made in 2008 and 2009, decreasing the total receivable from the pension trust to $96 million. The remaining $96 million balance was repaid in April 2010.

CASH FROM FINANCING ACTIVITIES

Cash from financing activities includes:

• issuances and payment of long-term debt,

• borrowings and payments under revolving lines of credit,

• changes in our book overdrafts,

• proceeds from stock offerings and option exercises and

• payment of cash dividends.

Debt

We repaid debt of:

• $20 million in first quarter 2010 and

• $1 million in first quarter 2009.

24

Long-term debt and revolving credit facilities

Weyerhaeuser Company and Weyerhaeuser Real Estate Company (WRECO) have a $1.0 billion 5-year revolving credit facility that expires in December 2011 (Credit Facility). WRECO can borrow up to $200 million under this facility. Neither of the entities is a guarantor of the borrowing of the other under this credit facility. In March 2010, Weyerhaeuser Company’s $400 million revolving credit facility expired and was not renewed.

There were no net proceeds from the issuance of debt or from borrowings (repayments) under our available credit facility in the first quarters of 2010 or 2009.

Debt covenants

As of March 31, 2010 Weyerhaeuser Company and WRECO:

• had no borrowings outstanding under the credit facilities,

• had $23 million in letters of credit drawn under the 2011 facility and

• were in compliance with the credit facility covenants.

Weyerhaeuser Company Covenants:

Key covenants related to Weyerhaeuser Company include the requirement to maintain:

• a minimum defined net worth of $3.0 billion and

• a defined debt-to-total-capital ratio of 65 percent or less.

Weyerhaeuser Company’s defined net worth is comprised of:

• total Weyerhaeuser shareholders’ interest,

• plus or minus accumulated comprehensive loss balance related to deferred pension and postretirement income or expense,

• minus Weyerhaeuser Company’s investment in subsidiaries in our Real Estate segment or other unrestricted subsidiaries.

Total Weyerhaeuser Company capitalization is comprised of:

• total Weyerhaeuser Company (excluding WRECO) debt

• plus total defined net worth.

As of March 31, 2010, Weyerhaeuser Company had:

• a defined net worth of $4.3 billion and

• a defined debt-to-total-capital ratio of 55.6 percent.

Weyerhaeuser Real Estate Company Covenants

Key covenants related to WRECO revolving credit facilities and medium-term notes include the requirement to maintain:

• a minimum defined net worth of $100 million,

• a defined debt-to-total-capital ratio of 80 percent or less and

• Weyerhaeuser Company or a subsidiary must own at least 79 percent of WRECO.

WRECO’s defined net worth is:

• total WRECO shareholders’ interest,

• minus intangible assets,

• minus WRECO’s investment in joint ventures and partnerships.

Total WRECO defined debt is:

• total WRECO debt – including any intercompany debt

• plus outstanding WRECO guarantees and letters of credit.

Total WRECO capitalization is defined as:

• total WRECO defined net worth.

As of March 31, 2010, WRECO had:

• a defined net worth of $799 million and

• a defined debt-to-total-capital ratio of 61.5 percent.

Paying dividends and repurchasing stock

We paid dividends of:

• $11 million in first quarter 2010 and

• $53 million in first quarter 2009.

The decrease in dividends paid is primarily due to the decrease in our quarterly dividend from 25 cents to 5 cents in July 2009.

During 2009, we repurchased 66,691 shares of common stock at a cost of $2 million under the stock-repurchase program authorized by the board of directors in December 2008.

25

OTHER LIQUIDITY RELATED DISCLOSURES

Expected Pension Funding

At the end of 2009, we reported that we intended to make a voluntary contribution of approximately $100 million to our U.S. qualified pension plans for the 2009 year by September 15, 2010. We contributed $100 million to our U.S. qualified pension plans in first quarter 2010. The contribution reduced 2009 taxable income, thereby increasing the amount of the 2009 operating loss refund that we received in first quarter 2010. The contribution also decreased the amount of earnings and profits that would have to be distributed in 2010 in order to convert to a real estate investment trust. The company estimates the required 2010 contribution could be as much as $20 million, which would be due by September 15, 2011.

Real Estate Investment Trust (REIT) Conversion

We announced in December 2009 that our board had determined that conversion to a REIT would best support the company’s strategic direction. Factors that the board will consider in determining the timing of converting to a REIT include the state of the economic recovery, changes in tax policy including shareholder tax rates and the distribution of earnings and profits required under tax laws for REIT election. We believe that 2010 is the most likely year in which conversion will occur. Following are points related to conversion:

• To implement our decision to be taxed as a REIT, the company is required to distribute our accumulated earnings and profits to our shareholders in a special dividend. The total amount of earnings and profits as of the beginning of the year is between $5.5 and $5.7 billion. The board intends to cap the cash portion of the payout at 10 percent, or approximately $550 to $570 million, assuming a 2010 conversion.

• We received shareholder approval on April 15, 2010 to issue a significant number of shares to enable the payout of earnings and profits to shareholders. See “Notes to Consolidated Financial Statements - Note 15: Subsequent Events” for more information.

• We will reverse certain current and deferred income tax liabilities and estimate that this would result in a benefit in the Consolidated Statement of Operations of approximately $1 billion based on current balances.

• The stock portion of the earnings and profits distribution would be treated as the issuance of new shares for accounting purposes. See “Notes to Consolidated Financial Statements - Note 2: Accounting Pronouncements” for more information. The required treatment will result in dilution of our earnings (loss) per share.

CRITICAL ACCOUNTING POLICIES

The preparation of our consolidated financial statements requires us to make judgments and estimates that affect our assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities.

In accounting, we base our judgments and estimates on:

• historical experience and

• assumptions we believe are appropriate and reasonable under current circumstances.

Actual results, however, may differ from the estimated amounts we have recorded. For a full description of our critical accounting policies, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2009 Annual Report on Form 10-K.

26

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

No changes occurred during first quarter 2010 that had a material effect on the information relating to quantitative and qualitative disclosures about market risk that was provided in the company’s Annual Report on Form 10-K for the year ended December 31, 2009.

CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

Disclosure controls are controls and other procedures that are designed to ensure that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. The company’s principal executive officer and principal financial officer have concluded that the company’s disclosure controls and procedures were effective as of March 31, 2010 based on an evaluation of the company’s disclosure controls and procedures as of that date.

CHANGES IN INTERNAL CONTROLS

No changes occurred in the company’s internal control over financial reporting during first quarter that have materially affected, or are reasonably likely to materially affect, the company’s internal control over financial reporting.

LEGAL PROCEEDINGS

Refer to “Notes to Consolidated Financial Statements – Note 14: Legal Proceedings, Commitments and Contingencies.”

RISK FACTORS

There have been no significant changes during first quarter 2010 to risk factors presented in the company’s 2009 Annual Report on Form 10-K.

UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In December 2008, we announced a stock-repurchase program under which we are authorized to repurchase up to $250 million of outstanding shares. We repurchased a total of 66,691 shares of common stock for approximately $2 million under the program during first quarter 2009. All common stock purchases under the program were made in open-market transactions. We have not repurchased any more common shares since first quarter 2009.

3. The preferences, limitations and relative rights of the preferred shares of each series, the preference shares of each series and the common shares are as follows:

(a) Out of the funds of the corporation legally available for payment of dividends, the holders of the preferred shares of each series and the preference shares of each series shall be entitled to receive, when and as declared by the Board of Directors, cumulative dividends at the rate determined by the Board of Directors for such series, and no more. Dividends on the preferred shares and the preference shares shall accrue on a daily basis from such date as may be fixed by the Board of Directors for any series. Unless dividends at the rate prescribed for each series of preferred shares shall have been declared and paid or set apart for payment in full on all outstanding preferred shares for all past dividend periods and the current dividend period, no dividends shall be declared or paid upon any class of shares ranking as to dividends subordinate to the preferred shares, and no sum or sums shall be set aside for the redemption of preferred shares of any series (including any sinking fund payment therefor) or for the purchase, redemption (including any sinking fund payment therefor) or other acquisition for value of any class or series of shares ranking as to dividends or assets on a parity with or subordinate to any such series of preferred shares. Unless dividends at the rate prescribed for each series of preference shares shall have been declared and paid or set apart for payment in full on all outstanding preference shares for all past dividend periods and the current dividend period, no dividends shall be declared or paid upon any class of shares ranking as to dividends subordinate to the preference shares, and no sum or sums shall be set aside for the redemption of preference shares of any series (including any sinking fund payment therefor) or for the purchase, redemption (including any sinking fund payment therefor) or other acquisition for value of any class or series of shares ranking as to dividends or assets on a parity with or subordinate to any such series of preference shares. Accrued and unpaid dividends on the preferred shares and on the preference shares shall not bear interest.

2

(b) Out of any funds of the corporation legally available for dividends and remaining after full cumulative dividends upon all series of preferred shares and preference shares then outstanding shall have been paid or set apart for payment for all past dividend periods and the current dividend period, then, and not otherwise, the Board of Directors may declare and pay or set apart for payment dividends on the common shares, and the holders of preferred shares and preference shares shall not be entitled to share therein.

(c) In the event of voluntary or involuntary liquidation of the corporation, before any distribution of the assets shall be made to the holders of any class of shares ranking as to assets subordinate to the preferred shares, the holders of the preferred shares of each series shall be entitled to receive out of the assets of the corporation available for distribution to its shareholders the sum of (i) the amount per share determined by the Board of Directors as provided in paragraph 2(c) of this Article III, and (ii) the amount per share equal to all accrued and unpaid dividends thereon, such sum constituting the “preferential amount” for the preferred shares. If, in the event of such liquidation, the assets of the corporation available for distribution to its shareholders shall be insufficient to permit full payment to the holders of the preferred shares of each series of their respective preferential amounts, then such assets shall be distributed ratably among such holders in proportion to their respective preferential amounts. In the event of such liquidation, subject to such right of the holders of the preferred shares of each series, but before any distribution of the assets shall be made to the holders of any class of shares ranking as to assets subordinate to the preference shares, the holders of the preference shares of each series shall be entitled to receive out of the assets of the corporation available for distribution to its shareholders the sum of (i) the amount per share determined by the Board of Directors as provided in paragraph 2(c) of this Article III, and (ii) the amount per share equal to all accrued and unpaid dividends thereon, such sum constituting the “preferential amount” for the preference shares. If, in the event of such liquidation, after full payment of the preferential amounts of the preferred shares of each series, the assets of the corporation available for distribution to its shareholders shall be insufficient to permit full payment to the holders of the preference shares of each series of their respective preferential amounts, then such assets shall be distributed ratably among such holders in proportion to their respective preferential amounts. If, in the event of such liquidation, the holders of the preferred shares of each series and the preference shares of each series shall have received full payment of their respective preferential amounts, the holders of the common shares shall be entitled, to the exclusion of the holders of the preferred shares of each series and the preference shares of each series, to share ratably in all remaining assets of the corporation available for distribution to shareholders. Neither the consolidation nor merger of the corporation with or into any other corporation or corporations, the sale or lease of all or substantially all of the assets of the corporation, nor the merger or consolidation of any other corporation into and with the corporation, shall be deemed to be a voluntary or involuntary liquidation.

(d) Each outstanding preferred share shall be entitled to one vote, not as a class, on each matter submitted to a vote at a meeting of shareholders, and the holders of preference shares shall have no voting rights except as provided in this Article III, provided, however, that if

3

the Board of Directors is permitted by law to vary voting rights as between series of a class, and does in fact do so, then the voting rights of any series of either class shall be those determined by the Board of Directors under paragraph 2(f) of this Article III. Notwithstanding the foregoing: (i) as long as any preferred shares shall be outstanding, the corporation will not, without the affirmative vote or consent in writing of at least two-thirds of the outstanding preferred shares, amend these Articles of Incorporation for the purpose of, or take any other action to, (A) increase the aggregate number of preferred shares or shares of any other class ranking as to dividends or assets on a parity with or prior to the preferred shares, (B) change the designations, preferences, limitations, voting or other relative rights of the preferred shares or of any outstanding series of preferred shares, (C) effect an exchange, reclassification or cancellation of all or part of the preferred shares, (D) change the preferred shares into the same or a different number of shares, with or without par value of the same or any other class, or (E) cancel or otherwise affect dividends on the shares of any series of preferred shares which have accrued but have not been declared, and (ii) as long as any preference shares shall be outstanding, the corporation will not, without the affirmative vote or consent in writing of at least two-thirds of the outstanding preference shares, amend these Articles of Incorporation for the purpose of, or take any other action to, (A) increase the aggregate number of preferred or preference shares or shares of any other class ranking as to dividends or assets on a parity with or prior to the preference shares, (B) change the designations, preferences, limitations, voting or other relevant rights of the preference shares or of any outstanding series of preference shares, (C) effect an exchange, reclassification or cancellation of all or part of the preference shares, (D) change the preference shares into the same or a different number of shares, with or without par value, of the same or another class, or (E) cancel or otherwise affect dividends on the shares of any series of preference shares which have accrued but have not been declared.

(e) Whenever dividends on the preferred shares shall be in arrears in an aggregate amount equal to at least six quarterly dividends thereon, whether or not consecutive, then the holders of the preferred shares, voting as a class, shall be exclusively entitled to elect two additional directors beyond the number specified in the bylaws to be elected from time to time by all shareholders and beyond the number specified in this paragraph (e) to be elected by holders of the preference shares. Whenever dividends on the preference shares shall be in arrears in an aggregate amount equal to at least six quarterly dividends thereon, whether or not consecutive, then the holders of the preference shares, voting as a class, shall be exclusively entitled to elect two additional directors beyond the number specified in the bylaws to be elected from time to time by all shareholders and beyond the number specified in this paragraph (e) to be elected by holders of the preferred shares.

(f) At any time when the holders of a class of shares become entitled as a class to elect additional directors pursuant to paragraph 3(e) of this Article III (the “special voting rights”), the maximum authorized number of members of the Board of Directors shall automatically be increased by the number of such directors specified in such paragraph 3(e) and the vacancies so created shall be filled only by vote of the holders of such class as hereinafter set forth. Whenever the special voting rights of a class shall have vested, such rights may be exercised initially either at a special meeting of the holders of such class called as hereinafter provided or at any annual meeting of shareholders held for the purpose of electing directors, and thereafter at such annual meetings. If, at the time of the vesting of the special voting rights of a class, the date fixed for the

4

next annual meeting of shareholders is not within 90 days of such time, the president of the corporation shall call a special meeting of the holders of such class. Such special meeting shall be held at the earliest practicable date upon the notice required and at the place designated for annual meetings of shareholders. If such special meeting shall not be called by the president within 20 days after the special voting rights of such class shall have vested, holders of not less than one-tenth of the shares of such class entitled to vote at such special meeting may call such special meeting at the expense of the corporation. Any holder of shares of a class, the special voting rights for which shall have vested, shall have access to the appropriate share ledger of the corporation for the purpose of causing such special meeting to be so called. At any annual meeting of shareholders or at any special meeting at which the holders of a class of shares shall have special voting rights, 20% of the shares of such class entitled to special voting rights, represented in person or by proxy, shall constitute a quorum for such class. At any such meeting or adjournment thereof, (i) the absence of a quorum of a class of shares having special voting rights shall not prevent the election of directors, if any, to be elected pursuant to other special voting rights or pursuant to other than special voting rights, and the absence of a quorum of shares for the election of directors pursuant to other than special voting rights shall not prevent the election of directors pursuant to special voting rights, and (ii) in the absence of one or more of such quorums, a majority of the holders, represented in person or by proxy, of each class of shares which lacks a quorum shall have power to adjourn the meeting for the election of directors which they are entitled to elect, from time to time, without notice other than announcement at the meeting, until a quorum shall be present. If the office of any director elected pursuant to the special voting rights of a class becomes vacant by reason of death, resignation, retirement, disqualification, removal from office, or otherwise, the remaining director or directors elected pursuant to the special voting rights of such class shall choose a successor who shall hold office for the unexpired term in respect of which such vacancy occurred. The special voting rights of a class shall continue until all arrears in payment of quarterly dividends on such class shall have been paid and the dividends thereon for the current quarter shall have been declared and paid or set apart for payment. Upon any termination of the special voting rights of a class, the term of office of the directors then in office elected pursuant thereto shall terminate immediately and the maximum authorized number of members of the Board of Directors shall automatically be reduced accordingly.

(g) Subject to any applicable provision of law or this Article III, the corporation shall have the right to purchase, or otherwise reacquire, at public or private sale or otherwise any shares of any class, except that no preferred shares shall be purchased unless dividends on all preferred shares have been declared and paid or set apart for payment in full for all past dividend periods and no preference shares shall be purchased unless dividends on all preference shares have been declared and paid or set apart for payment in full for all past dividend periods.

4. The Board of Directors may from time to time authorize the issuance of shares of this corporation, whether now or hereafter authorized, without first offering such shares to the shareholders of this corporation.

ARTICLE IV

The time of the existence of this corporation shall be perpetual.

Whenever used in these Articles of Incorporation, the phrase “entire Board of Directors” shall mean that number of directors fixed by the most recent resolution adopted pursuant to the preceding sentence prior to the date as of which a determination of the number of directors then constituting the entire Board of Directors shall be relevant for any purpose under these Articles of Incorporation At each annual meeting of shareholders of the corporation, the successors to each director whose term expires at that meeting shall be elected to hold office for a term expiring at the next annual meeting of shareholders.
