The condensed consolidated financial statements as of June 30, 2008 and 2007 of Packaging Corporation of America (“PCA” or the “Company”) and for the three- and six-month periods then ended are unaudited but include all adjustments (consisting only of normal recurring adjustments) that management considers necessary for a fair presentation of such financial statements. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with Article 10 of SECRegulation S-X.Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete audited financial statements. Operating results for the period ended June 30, 2008 are not necessarily indicative of the results that may be expected for the year ending December 31, 2008. These condensed consolidated financial statements should be read in conjunction with PCA’s Annual Report onForm 10-Kfor the year ended December 31, 2007.

The accompanying condensed consolidated financial statements of PCA include all majority-owned subsidiaries. All intercompany transactions have been eliminated. The Company has one joint venture that is accounted for under the equity method.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts in the financial statements and the accompanying notes. Actual results could differ from those estimates.

The Company recognizes revenue as title to the products is transferred to customers. Shipping and handling billings to a customer are included in net sales. Shipping and handling costs are included in cost of sales. In addition, the Company offers volume rebates to certain of its customers. The total cost of these programs is estimated and accrued as a reduction to net sales at the time of the respective sale.

PCA is engaged in one line of business: the integrated manufacture and sale of packaging materials, boxes and containers for industrial and consumer markets. No single customer accounts for more than 10% of total net sales.

Comprehensive income is as follows:

On June 12, 2003, in connection with a contemplated issuance of five-year and ten-year debt securities, PCA entered into interest rate protection agreements with a counterparty to protect against increases in the five-year and ten-year U.S. Treasury Note rates. On January 17, 2008, in connection with the issuance of ten-year debt securities in March 2008, PCA entered into an interest rate protection agreement with a counterparty to protect against increases in the ten-year U.S. Treasury Note rate. These treasury rates served as references in determining the interest rates applicable to the debt securities the Company issued in July 2003 and March 2008. As a result of changes in the interest rates on those treasury securities between the time PCA entered into the agreements and the time PCA priced and issued the debt securities, the Company: (1) received a payment of $27.0 million from the counterparty upon settlement of the 2003 interest rate protection agreements on July 21, 2003; and (2) made a payment of $4.4 million to the counterparty upon settlement of the 2008 interest rate protection agreement on March 25, 2008. The Company recorded the settlements in accumulated other comprehensive income (loss) and is amortizing the $27.0 million gain and $4.4 million loss to interest expense over the lives of the respective notes.

In March 2008, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 161, “Disclosures about Derivative Instruments and Hedging Activities.” SFAS No. 161 changes the disclosure requirements for derivative instruments and hedging activities. Entities will be required to provide enhanced disclosures about how and why an entity uses derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities”

In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations.” SFAS No. 141(R) significantly changes the accounting for and reporting of business combination transactions in consolidated financial statements. These significant changes include: (1) recognition of 100% of the fair value of assets acquired, liabilities assumed and noncontrolling interests of acquired businesses, even if 100% of the business has not been acquired; (2) recognition of contingent consideration arrangements and preacquisition gain and loss contingencies at their acquisition-date fair values; (3) capitalization of research and development assets acquired at acquisition-date fair value; (4) recognition of acquisition-related transaction costs as expense when incurred; and (5) recognition of acquisition-related restructuring cost accruals only if the criteria in SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities,” are met as of the acquisition date. SFAS No. 141(R) is effective for fiscal years beginning after December 15, 2008. Early adoption is not permitted. To the extent the Company makes an acquisition after December 31, 2008, SFAS No. 141(R) will impact the Company’s accounting for such acquisition.

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.” This Statement permits entities to choose to measure many financial instruments and certain other items at fair value. Most of the provisions of SFAS No. 159 apply only to entities that elect the fair value option. However, the amendments to SFAS No. 115, “Accounting for Certain Investments In Debt and Equity Securities,” apply to all entities with available-for-sale and trading securities. SFAS No. 159 was effective as of the beginning of an entity’s first fiscal year that began after November 15, 2007. On January 1, 2008, the Company decided not to adopt the fair value option for any of its financial instruments.

In September 2006, the FASB issued 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 No. 158 requires plan sponsors of defined benefit pension and other postretirement benefit plans (collectively, “postretirement benefit plans”) to recognize the funded status of their postretirement benefit plans in the statement of financial position, measure the fair value of plan assets and benefit obligations as of the date of the fiscal year end statement of financial position, and provide additional disclosures. These requirements were effective for fiscal years ending after December 15, 2006, with the exception of the requirement to measure plan assets and benefit obligations as of the plan sponsor’s fiscal year-end. This requirement is effective for fiscal years ending after December 15, 2008. On December 31, 2006, the Company adopted the recognition and disclosure provisions of SFAS No. 158. The Company will adopt the measurement provision of SFAS No. 158 by December 31, 2008, as required. The cumulative effect of adopting this provision will be recorded in retained earnings and other accounts as applicable. The Company expects that the adoption of the measurement provision of SFAS No. 158 will decrease retained earnings by $3.3 million, increase the obligation for pension and postretirement benefit plans by $5.5 million, and decrease deferred taxes by $2.2 million.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements would be separately disclosed by level within the fair value hierarchy. This Statement was effective for fiscal years beginning after November 15, 2007. The Company adopted SFAS No. 157 on January 1, 2008. For additional information regarding SFAS No. 157, see Note 9.

The following table sets forth the computation of basic and diluted income per common share for the periods presented.

In October 1999, the Company adopted a long-term equity incentive plan, which provides for grants of stock options, stock appreciation rights, restricted stock and performance awards to directors, officers and employees of PCA, as well as others who engage in services for PCA. Option awards granted to directors, officers and employees have contractual lives of seven or ten years. Options granted to officers and employees vest ratably over a three- or four-year period, whereas options granted to directors vest immediately. The plan, which will terminate on October 19, 2009, provides for the issuance of up to 6,550,000 shares of common stock. As of June 30, 2008, options or restricted stock for 5,816,661 shares have been granted, net of forfeitures. Forfeitures are added back to the pool of shares of common stock available to be granted at a future date. On July 2, 2008, the Company granted

The Company measures and records stock-based compensation cost in accordance with SFAS No. 123(R), “Share-Based Payment.” Stock compensation cost includes: (a) compensation cost for all share-based payments granted prior to, but not vested, as of January 1, 2006, the effective date of SFAS 123(R), based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123, and (b) compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123(R). Compensation expense for both stock options and restricted stock recognized in the condensed consolidated statements of income for the three- and sixth- month periods ended June 30, 2008 and 2007 was as follows:

The Company uses the Black-Scholes-Merton option-pricing model to estimate the fair value of each option grant as of the date of grant. Expected volatilities are based on historical volatility of the Company’s common stock. The expected life of the option is estimated using historical data pertaining to option exercises and employee terminations. Separate groups of employees that have similar historical exercise behavior are considered separately for estimating the expected life. The risk-free interest rate is based on U.S. Treasury yields in effect at the time of grant. There were no option grants during the first six months of 2008.

A summary of the Company’s stock option activity and related information follows:

The total intrinsic value of options exercised during the three months ended June 30, 2008 and 2007 was $388,000 and $3,285,000, respectively, and during the six months ended June 30, 2008 and 2007 was $753,000 and

During 2003, the Company began granting shares of restricted stock to certain of its employees and directors. Restricted stock awards granted to employees vest at the end of a three- or four-year period, whereas restricted stock awards granted to directors vest at the end of a six-month period. The fair value of restricted stock is determined based on the closing price of the Company’s common stock on the grant date. The Company generally recognizes compensation expense associated with restricted stock awards ratably over their vesting periods. As PCA’s Board of Directors has the ability to accelerate vesting of restricted stock upon an employee’s retirement, the Company accelerates the recognition of compensation expense for certain employees approaching normal retirement age. A summary of the Company’s restricted stock activity follows:

As of June 30, 2008, there was $5,894,000 of total unrecognized compensation costs related to the above restricted stock awards. The Company expects to recognize the cost of these stock awards over a weighted-average period of 2.3 years.

The components of inventories are as follows:

An actual valuation of inventory under the LIFO method is made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations must necessarily be based on management’s estimates of expected year-end inventory levels and costs. Because these are subject to many factors beyond management’s control, interim results are subject to the final year-end LIFO inventory valuation.

There were no changes in the carrying amount of goodwill for the period ended June 30, 2008.

The components of other intangible assets are as follows:

For the three and six months ended June 30, 2008 and 2007, net pension costs were comprised of the following:

The Company makes pension plan contributions that are sufficient to fund its actuarially determined costs, generally equal to the minimum amounts required by the Employee Retirement Income Security Act (ERISA). However, from time to time the Company may make discretionary contributions in excess of the required minimum amounts. The Company expects to contribute $25.4 million to the pension plans in 2008, of which $11.3 million has been contributed through June 30, 2008.

For the three and six months ended June 30, 2008 and 2007, net postretirement costs were comprised of the following:

A summary of debt is set forth in the following table:

On March 25, 2008, PCA issued $150.0 million of 6.50% senior notes due March 15, 2018 through a registered public offering. PCA used the proceeds of this offering, together with cash on hand, to repay all of the $150.0 million of outstanding 43/8% senior notes on August 1, 2008.

On April 15, 2008, PCA replaced its existing senior credit facility that was scheduled to expire later in 2008, with a new five-year $150.0 million senior revolving credit facility. As of June 30, 2008, the Company had $130.6 million in unused borrowing capacity under this facility due to the impact on this borrowing capacity of $19.4 million of outstanding letters of credit.

The instruments governing PCA’s indebtedness contain covenants that limit the ability of PCA and its subsidiaries to enter into sale and leaseback transactions, incur liens, enter into certain transactions with affiliates, merge or consolidate with any other person or sell or otherwise dispose of all or substantially all of the assets of the Company. The senior credit facility also requires PCA to comply with certain financial covenants, including maintaining a minimum interest coverage ratio, a maximum ration of debt to total capitalization, and a minimum net worth level. A failure to comply with these restrictions could lead to an event of default, which could result in an acceleration of any outstanding indebtednessand/orprohibit us from drawing on the revolving credit facility. At June 30, 2008, the Company was in compliance with these covenants.

PCA adopted SFAS No. 157 on January 1, 2008. SFAS No. 157 defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. SFAS No. 157 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, SFAS No. 157 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1 — observable inputs such as quoted prices in active markets

Level 2 — inputs, other than quoted prices in active markets, that are observable either directly or indirectly

Level 3 — unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions

Assets and liabilities measured at fair value are based on one or more of three valuation techniques noted in SFAS No. 157. The valuation techniques are as follows:

Assets and liabilities measured at fair value on a recurring basis are as follows:

There were no changes in the Company’s valuation techniques used to measure fair values on a recurring basis as a result of adopting SFAS No. 157. PCA had no assets or liabilities that were measured on a nonrecurring basis.

On October 17, 2007, the Company announced that its Board of Directors authorized a $150.0 million common stock repurchase program. There is no expiration date for the common stock repurchase program. Through June 30, 2008, the Company repurchased 2,546,029 shares of common stock, with 984,400 shares repurchased during the second quarter of 2008. As of June 30, 2008, $88.6 million of the $150.0 million authorization remains available for repurchase of the Company’s common stock.

Packaging Corporation of America, or PCA, is the fifth largest producer of containerboard and corrugated products in the United States, based on production capacity. During the second quarter of 2008, we produced approximately 614,000 tons of containerboard at our mills, of which about 80% was consumed in our corrugated products manufacturing plants, 13% was sold to domestic customers and 7% was sold in the export market. Our corrugated products manufacturing plants sold about 8.0 billion square feet (“bsf”) of corrugated products during the second quarter of 2008. Our net sales to third parties totaled $616.2 million in second quarter 2008, and were $1,193.7 million for the six months ended June 30, 2008.

Besides containerboard, we produce a wide variety of products ranging from basic corrugated shipping containers to specialized packaging such as wax-coated boxes for the agriculture industry. We also have multi-color printing capabilities to make high-impact graphics boxes and displays that offer our customers more attractive packaging. Our operating facilities and customers are located primarily in the United States.

In analyzing the operating performance of the company, we focus on the following factors that affect our business and are important to consider when reviewing our financial and operating results:

The market for containerboard is generally subject to changes in the U.S. economy. Historically, supply and demand, as well as industry-wide inventory levels, have influenced prices of containerboard. In addition to U.S. shipments, approximately 10% of domestically produced containerboard has been exported for use in other countries.

Reported industry-wide shipments of corrugated products decreased 2.1% for the three months ended June 30, 2008 compared to the same period in 2007. During this same period, industry containerboard inventory levels remained at historically low levels. Industry inventories of containerboard at the end of the second quarter were at the lowest June ending level in the past 30 years on a weeks-of-supply basis. Industry publications reported that linerboard prices remained unchanged during the second quarter and were $40 per ton higher than the second quarter of 2007 due to the August 2007 $40 per ton containerboard price increase. After the end of the second quarter of 2008, July industry publications reported that prices for containerboard, both linerboard and corrugating medium, had risen an additional $55 per ton.

The cost to manufacture containerboard is dependent, in large part, on the costs of wood fiber, recycled fiber, purchased fuels, electricity and labor and fringe benefits. While energy and other costs are significant in the manufacture of corrugated products, labor and fringe benefits make up the largest component of corrugated products’ manufactured costs, excluding the cost of containerboard.

During the second quarter of 2008, purchased fuel costs increased significantly from virtually all sources. Price increases occurred in fuels such as natural gas, fuel oil and diesel and related products such as chemicals and electricity. The impact of these fuel increases also affected transportation costs for inbound materials such as wood and recycled fiber as well as for outbound finished goods. Energy related costs were higher than the first quarter of 2008 and also the second quarter of 2007. Although industry publications reported that average prices for recycled fiber in the second quarter of 2008 were about 20% higher than the second quarter of 2007, monthly prices declined during the second quarter.

For the quarter ended June 30, 2008, PCA’s net income was lower than the prior year’s second quarter. The decline was primarily due to increased costs of energy and energy related items,start-upcosts for two major mill projects, costs related to debt refinancing, mill maintenance outage costs, labor costs and tornado damage at two

We expect our income from operations for the third quarter of 2008 to be higher than our income from operations for the second quarter of 2008, primarily due to higher prices for containerboard and corrugated products and no planned mill downtime for maintenance work. These increases are expected to be partially offset by higher prices paid for energy and energy related items, including transportation, chemicals and materials.

The historical results of operations of PCA for the three months ended June 30, 2008 and 2007 are set forth below:

Net sales increased by $30.6 million, or 5.2%, for the three months ended June 30, 2008 from the comparable period in 2007, primarily as a result of increased sales prices of corrugated products and containerboard to third parties. The increased sales prices resulted from the August 2007 increase in containerboard prices described above and the realization of those price increases in our sales of corrugated products and containerboard.

Total corrugated products volume sold for the three months ended June 30, 2008 decreased 0.4% to 7.97 billion square feet (“bsf”) compared to 8.0 bsf in the second quarter of 2007. On a comparableshipment-per-workdaybasis, corrugated products sales volume decreased 2.0% for the three months ended June 30, 2008 compared to the same period in 2007. The percentage decrease, on ashipment-per-workdaybasis, was higher due to one additional workday in the second quarter of 2008 (64 days), those days not falling on a weekend or holiday, than the second quarter of 2007 (63 days). Containerboard volume sold to domestic and export customers was 3.3% higher for the three months ended June 30, 2008 compared to the three months ended June 30, 2007. Containerboard mill production for the three months ended June 30, 2008 was 614,000 tons compared to 615,000 tons in the same period in 2007.

Income from operations decreased by $16.1 million, or 20.0%, for the three months ended June 30, 2008 compared to the three months ended June 30, 2007, primarily attributable to increased energy and energy related costs ($22.8 million), annual mill maintenance outage and repair costs ($5.1 million), labor costs ($3.4 million), expenses related to thestart-up of two major mill projects and facility tornado damage ($2.7 million), medical costs ($2.5 million), fixed asset write-offs primarily related to mill capital projects ($1.5 million) and other increased costs which were individually insignificant. The impact of higher costs was partially offset by increased sales prices for corrugated products and containerboard ($25.3 million).

Gross profit decreased $12.9 million, or 9.2%, for the three months ended June 30, 2008 from the comparable period in 2007. Gross profit as a percentage of net sales decreased from 23.9% of net sales in the three months ended June 30, 2007 to 20.6% of net sales in the current quarter due primarily to the cost increases described above.

Selling and administrative expenses increased $0.7 million, or 1.6%, for the three months ended June 30, 2008 compared to the same period in 2007, primarily as a result of higher expenses related to travel, meeting and entertainment expenses ($0.4 million) and higher warehousing costs due to customer requirements ($0.3 million).

Corporate overhead decreased $0.8 million, or 5.2%, for the three months ended June 30, 2008 compared to the same period in 2007, primarily due to a reduction in travel, meeting and entertainment costs ($0.3 million) and a decrease in professional fees paid for human resource and other matters ($0.3 million).

Other expense for the three months ended June 30, 2008 increased $3.2 million, or 139.6%, compared to the three months ended June 30, 2007, primarily related to increased fixed asset write-offs described above ($1.5 million), tornado damage to facilities ($0.9 million) and an increase in legal expenses ($0.6 million).

Net interest expense increased $1.3 million, or 18.3%, for the three months ended June 30, 2008 from the three months ended June 30, 2007, primarily as a result of additional interest expense on the Company’s higher debt levels as of June 30, 2008 compared to the same period in 2007, partially offset by lower interest expense on the Company’s receivables credit facility due to lower interest rates.

PCA’s effective tax rate was 37.1% for the three months ended June 30, 2008 and 36.9% for the comparable period in 2007. The effective tax rate varies from the U.S. federal statutory tax rate of 35% principally due to the impact of state and local income taxes offset by the domestic manufacturers’ deduction. The Company had no material changes impacting FIN No. 48 during the second quarter of 2008.

The historical results of operations of PCA for the six months ended June 30, 2008 and 2007 are set forth below:

Net sales increased by $48.9 million, or 4.3%, for the six months ended June 30, 2008 from the comparable period in 2007, primarily due to increased sales prices of corrugated products and containerboard to third parties.

Corrugated products volume sold for the six months ended June 30, 2008 decreased 0.7% compared to the same period in 2007 on a total andshipment-per-workdaybasis. Total corrugated products shipments decreased 0.1 bsf from 15.7 bsf in the first six months of 2007 to 15.6 bsf in the first half of 2008. Containerboard volume sold to domestic and export customers was 0.4% lower for the six months ended June 30, 2008 compared to the six months ended June 30, 2007. Containerboard mill production for the first half of 2008 was 1,199,500 tons, which was equal to production during the same period in 2007.

Income from operations decreased by $15.6 million, or 11.4%, for the six months ended June 30, 2008 compared to the six months ended June 30, 2007, primarily attributable to increased energy and energy related costs ($37.5 million), labor and fringe benefit costs ($7.2 million), mill maintenance outage costs ($5.3 million), recycled fiber costs ($3.6 million), medical costs ($3.5 million), fixed asset write-offs, primarily related to mill capital projects ($3.2 million), bad debt expense ($2.2 million) andstart-upcosts of two major mill projects ($1.9 million). The impact of higher costs was partially offset by increased sales prices for corrugated products and containerboard ($49.1 million).

Gross profit decreased $7.8 million, or 3.1%, for the six months ended June 30, 2008 from the comparable period in 2007. Gross profit as a percentage of net sales decreased from 22.1% of net sales in the six months ended June 30, 2007 to 20.6% of net sales in the first half of 2008 due primarily to the cost increases described above.

Selling and administrative expenses increased $2.3 million, or 2.8%, for the six months ended June 30, 2008 compared to the same period in 2007, primarily as a result of higher expenses related to labor and fringe benefit costs ($0.8 million), travel, meeting and entertainment expenses ($0.7 million), warehousing costs ($0.5 million) and information technology costs ($0.2 million).

Corporate overhead for the six months ended June 30, 2008 increased 0.1% compared to the same period in 2007.

Other expense for the six months ended June 30, 2008 increased $5.4 million, or 144.7%, compared to the six months ended June 30, 2007, due to higher fixed asset write-offs primarily related to mill capital projects ($3.2 million), tornado damage to facilities ($0.9 million) and an increase in legal expenses ($0.9 million).

Net interest expense increased $0.4 million, or 3.1%, for the six months ended June 30, 2008 from the six months ended June 30, 2007, primarily as a result of additional interest expense on the Company’s higher debt levels as of June 30, 2008 compared to the same period in 2007, partially offset by lower interest expense on the Company’s receivables credit facility due to lower interest rates.

PCA’s effective tax rate was 37.0% for both the six months ended June 30, 2008 and June 30, 2007. The effective tax rate varies from the U.S. federal statutory tax rate of 35% principally due to the impact of state and local income taxes offset by the domestic manufacturers’ deduction. The Company had no material changes impacting FIN No. 48 during the first half of 2008.

The following table presents a summary of our cash flows for the periods presented:

Net cash provided by operating activities for the six months ended June 30, 2008 was $110.6 million, a decrease of $19.0 million, or 14.7%, from the comparable period in 2007. The decrease in net cash provided by operating activities was primarily the result of lower net income in 2008 of $10.2 million as previously described and higher requirements for operating assets and liabilities of $14.4 million, partially offset by a higher deferred tax provision of $6.3 million for the six months ended June 30, 2008 compared to the same period in 2007. The higher

Net cash used for investing activities for the six months ended June 30, 2008 increased $24.1 million, or 55.7%, to $67.3 million, compared to the six months ended June 30, 2007. The increase was primarily related to higher additions to property, plant and equipment of $23.7 million during the six months ended June 30, 2008 compared to the same period in 2007.

Net cash provided by financing activities totaled $26.2 million for the six months ended June 30, 2008, compared to net cash used for financing activities of $40.2 million for the comparable period in 2007, a difference of $66.3 million, or 165.1%. The difference was primarily attributable to $144.7 million in net proceeds received from PCA’s notes offering described below, partially offset by a debt prepayment of $20.0 million made in the first quarter of 2008, $36.8 million in repurchases of PCA common stock during the first six months of 2008, $10.4 million in additional dividends paid on PCA’s common stock during the first six months of 2008 compared to the same period in 2007, and lower proceeds from the issuance of common stock upon exercise of stock options of $9.3 million during the six months ended June 30, 2008 compared to the same period in 2007.

In connection with the notes offering in March of 2008, PCA received proceeds, net of discount, of $149.9 million and paid $4.4 million for settlement of a treasury lock that it entered into to protect it against increases in the ten-year U.S. Treasury rate, which served as a reference in determining the interest rate applicable to the notes. PCA also incurred financing costs in the amount of $0.8 million in connection with the notes offering.

PCA’s primary sources of liquidity are net cash provided by operating activities, borrowings under PCA’s revolving credit facility, and additional borrowings under PCA’s receivables credit facility. As of June 30, 2008, PCA had $171.6 million in unused borrowing capacity under its existing credit agreements, net of the impact on this borrowing capacity of $19.4 million of outstanding letters of credit. Currently, PCA’s primary uses of cash are for capital expenditures, debt service, declared common stock dividends and common stock repurchases, which it expects to be able to fund from these sources.

The following table provides the outstanding balances and the weighted average interest rates as of June 30, 2008 for PCA’s revolving credit facility, the receivables credit facility, and the five- and ten-year senior notes:

The above table excludes unamortized debt discount of $1.8 million at June 30, 2008. It also excludes from the projected annual cash interest payments, the non-cash income from the annual amortization of the $27.0 million received in July 2003 and the non-cash expense from the annual amortization of the $4.4 million paid in March 2008 to settle the treasury locks related to the five- and ten-year notes. The amortization is being recognized over the term of the five- and ten-year notes and is included in interest expense, net.

On March 25, 2008, PCA issued $150.0 million of 6.50% senior notes due March 15, 2018 through a registered public offering. PCA used the proceeds of this offering, together with cash on hand, to repay all of the $150.0 million of outstanding 43/8% senior notes on August 1, 2008.

On March 31, 2008, PCA repaid all borrowings under its old senior credit facility. This facility was replaced with a senior credit facility that provides a new $150.0 million revolving credit facility, including a $35.0 million subfacility for letters of credit. The new senior credit facility closed on April 15, 2008.

The new revolving credit facility is available to fund PCA’s working capital requirements, capital expenditures and other general corporate purposes. The new revolving credit facility will terminate in April 2013. The receivables credit facility will terminate in October 2008. The Company plans to refinance this facility in 2008.

The instruments governing PCA’s indebtedness contain financial and other covenants that limit, among other things, the ability of PCA and its subsidiaries to:

These limitations could limit our corporate and operating activities.

In addition, we must maintain minimum net worth, maximum debt to total capitalization and minimum interest coverage ratios under the senior credit facility. A failure to comply with the restrictions contained in our senior credit facility could lead to an event of default, which could result in an acceleration of any outstanding indebtednessand/orprohibit us from drawing on the revolving credit facility. Such an acceleration may also constitute an event of default under the notes indentures and the receivables credit facility. As of June 30, 2008, PCA was in compliance with these covenants.

PCA currently expects to incur capital expenditures of about $120.0 million in 2008. These expenditures will be used primarily for maintenance capital, cost reduction, business growth and environmental compliance. As of June 30, 2008, PCA spent $65.6 million for capital expenditures and had committed to spend an additional $56.0 million in the remainder of 2008 and beyond.

PCA believes that its net cash generated from operating activities, available cash reserves and available borrowings under its committed credit facilities and available capital through access to capital markets will be adequate to meet its current and future liquidity and capital requirements, including payments of any declared common stock dividends. As its debt or credit facilities become due, PCA will need to repay, extend or replace such facilities, which will be subject to future economic conditions and financial, business and other factors, many of which are beyond PCA’s control.

PCA is exposed to the impact of interest rate changes and changes in the market value of its financial instruments. PCA periodically enters into derivatives in order to minimize these risks, but not for trading purposes. On January 17, 2008, in connection with the issuance of ten-year debt securities in March 2008, PCA entered into an interest rate protection agreement with a counterparty to lock in the then current interest rate on ten-year U.S. Treasury notes to protect against increases in the ten-year U.S. Treasury note rate. This rate served as a

The interest rates on approximately 87% of PCA’s debt are fixed. A one percent increase in interest rates related to variable rate debt would have resulted in an increase in interest expense and a corresponding decrease in income before taxes of $1.1 million annually. In the event of a change in interest rates, management could take actions to mitigate its exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no changes in PCA’s financial structure.

We are subject to, and must comply with, a variety of federal, state and local environmental laws, particularly those relating to air and water quality, waste disposal and the cleanup of contaminated soil and groundwater. The most significant of these laws affecting us are:

We believe that we are currently in material compliance with these and all applicable environmental rules and regulations. Because environmental regulations are constantly evolving, we have incurred, and will continue to incur, costs to maintain compliance with these and other environmental laws. We work diligently to anticipate and budget for the impact of applicable environmental regulations, and do not currently expect that future environmental compliance obligations will materially affect our business or financial condition.

PCA does not believe that inflation has had a material impact on its financial position or results of operations during the three- and six-month periods ending June 30, 2008 and 2007.

PCA does not have any off-balance sheet arrangements as of June 30, 2008 that would require disclosure under SEC FR-67, “Disclosure in Management’s Discussion and Analysis About Off-Balance Sheet Arrangement and Aggregate Contractual Obligations.”

Management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to bad debts, inventories, intangible assets, pensions and other postretirement benefits, income taxes, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

PCA has included in its Annual Report onForm 10-Kfor the year ended December 31, 2007, a discussion of its critical accounting policies which we believe affect our more significant judgments and estimates used in the preparation of our consolidated financial statements. PCA has not made any changes in any of these critical accounting policies during the first six months of 2008.

Some of the statements in this Quarterly Report onForm 10-Q,and in particular, statements found in Management’s Discussion and Analysis of Financial Condition and Results of Operations, that are not historical in nature are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are often identified by the words “will,” “should,” “anticipate,” “believe,” “expect,” “intend,” “estimate,” “hope,” or similar expressions. These statements reflect management’s current views with respect to future events and are subject to risks and uncertainties. There are important factors that could cause actual results to differ materially from those in forward-looking statements, many of which are beyond our control. These factors, risks and uncertainties include the following:

Our actual results, performance or achievement could differ materially from those expressed in, or implied by, these forward-looking statements, and accordingly, we can give no assurances that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do occur, what impact they will have on our results of operations or financial condition. In view of these uncertainties, investors are cautioned not to place undue reliance on these forward-looking statements. We expressly disclaim any obligation to publicly revise any forward-looking statements that have been made to reflect the occurrence of events after the date hereof.

For a discussion of market risks related to PCA, see Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Market Risk and Risk Management Policies” in this Quarterly Report onForm 10-Q.

PCA maintains disclosure controls and procedures (as defined inRule 13a-15(e)of the Securities Exchange Act of 1934) that are designed to provide reasonable assurance that information required to be disclosed in PCA’s filings under the Securities Exchange Act is recorded, processed, summarized and reported within the periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to PCA’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Prior to filing this report, PCA completed an evaluation under the supervision and with the participation of PCA’s management, including PCA’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of PCA’s disclosure controls and procedures as of June 30, 2008. The evaluation of PCA’s disclosure controls and procedures included a review of the controls’ objectives and design, PCA’s implementation of the controls and the effect of the controls on the information generated for use in this report. Based on this

During the quarter ended June 30, 2008, there were no changes in internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, PCA’s internal control over financial reporting.

PCA is a party to various legal actions arising in the ordinary course of our business. These legal actions cover a broad variety of claims spanning our entire business. As of the date of this filing, we believe it is not reasonably possible that the resolution of these legal actions will, individually or in the aggregate, have a material adverse effect on our financial condition, results of operations or cash flows.

There have been no material changes to the risk factors disclosed in Item 1A. Risk Factors in our Annual Report onForm 10-Kfor the year ended December 31, 2007.
