CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.	Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited consolidated financial statements of Martin Marietta Materials, Inc. (the “Corporation”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and to Article 10 of Regulation S-X. The Corporation has continued to follow the accounting policies set forth in the audited consolidated financial statements and related notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2007, filed with the Securities and Exchange Commission on February 25, 2008. In the opinion of management, the interim financial information provided herein reflects all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the results of operations, financial position and cash flows for the interim periods. The results of operations for the three and six months ended June 30, 2008 are not indicative of the results expected for other interim periods or the full year.
	Comprehensive Earnings

(Continued)

1.	Significant Accounting Policies (continued)
	Accounting Changes
	Effective January 1, 2008, the Corporation partially adopted Statement of Financial Accounting Standards No. 157,Fair Value Measurements(“FAS 157”). FAS 157 does not require any new fair value measurements; rather, it establishes a framework for measuring fair value in generally accepted accounting principles, clarifies the definition of fair value within that framework and expands disclosures about the use of fair value measurements. FAS 157 applies to all accounting pronouncements that require fair value measurements, except for the measurement of share-based payments. Additionally, in February 2008, the Corporation adopted Financial Accounting Standards Board Staff Position No. FAS 157-2,Effective Date of FASB Statement No. 157(“FSP 157-2”). FSP 157-2 delays the effective date of FAS 157 for all nonrecurring fair value measurements of nonfinancial assets and nonfinancial liabilities until fiscal years beginning after November 15, 2008. At June 30, 2008, the categories of assets and liabilities to which the Corporation did not apply FAS 157 include: nonfinancial assets and liabilities initially measured at fair value in a business combination; reporting units measured at fair value in the first step of goodwill impairment testing; indefinite-lived intangible assets and nonfinancial long-lived assets measured at fair value for impairment assessment and asset retirement obligations.
	Reclassifications
	Certain 2007 amounts included on the consolidated balance sheet have been reclassed to conform to the 2008 presentation. The reclassifications had no impact on previously reported financial position.
2.	Business Combinations and Divestitures
	Business Combinations
	On April 11, 2008, the Corporation entered into a swap transaction with Vulcan Materials Company (“Vulcan”), pursuant to which it acquired six quarry locations in North Georgia and Tennessee. The newly acquired locations significantly expand the Corporation’s presence in high-growth areas of Georgia and Tennessee, particularly south and west of Atlanta. The Corporation also acquired a land parcel previously leased from Vulcan at the Corporation’s Three Rivers Quarry near Paducah, Kentucky. For the year ended December 31, 2007, the Corporation’s newly acquired locations shipped nearly 4.5 million tons of aggregates and have aggregates reserves that exceed 300 million tons. The operating results of the acquired quarries have been included with those of the Corporation since the date of acquisition and are being reported through the Corporation’s Southeast Group in the financial statements.

2.

Business Combinations and Divestitures (continued)

In addition to a $192,000,000 cash payment and normal closing adjustments related to working capital, the Corporation divested to Vulcan its only California quarry located in Oroville, an idle facility north of San Antonio, Texas, and land in Henderson, North Carolina, formerly leased to Vulcan. Furthermore, the Corporation recognized goodwill in the amount of $45,862,000. The fair values of the assets acquired from Vulcan were allocated as follows (dollars in thousands):

Inventories	$	6,559
Mineral reserves	$	113,825
Land	$	22,260
Machinery and equipment	$	41,929
Other intangibles	$	3,260

Discontinued Operations

During 2008, the Corporation disposed of or permanently shut down certain operations, including its Oroville, California quarry, which was included in the West Group and divested as part of the Vulcan swap transaction. These divestitures represent discontinued operations, and, therefore, the results of their operations through the dates of disposal and any gain or loss on disposals are included in discontinued operations on the consolidated statements of earnings.

The discontinued operations included the following net sales, pretax loss or gain on operations, pretax gain on disposals, income tax expense and overall net earnings:

5.	Long-Term Debt (continued)
	On April 21, 2008, the Corporation completed the issuance of $300,000,000 of 6.6% Senior Notes due in 2018 (the “6.6% Senior Notes”). The 6.6% Senior Notes, which are unsecured, may be redeemed in whole or in part prior to their maturity at a make whole redemption price. Upon a change of control repurchase event and a below investment grade credit rating, the Corporation will be required to make an offer to repurchase all outstanding 6.6% Senior Notes at a price in cash equal to 101% of the principal amount of the 6.6% Senior Notes, plus any accrued and unpaid interest to, but not including, the purchase date.
	In connection with the issuance of the 6.6% Senior Notes, on April 16, 2008, the Corporation unwound its two forward starting interest rate swap agreements with a total notional amount of $150,000,000 (the “Swap Agreements”). The Corporation made a cash payment of $11,139,000, which represented the fair value of the Swap Agreements on the date of termination. The accumulated other comprehensive loss at the date of termination will be recognized in earnings over the life of the 6.6% Senior Notes. For the quarter ended June 30, 2008, the Corporation recognized $165,000 of the accumulated other comprehensive loss as additional interest expense. At December 31, 2007 and June 30, 2007, the fair value of the Swap Agreements was a liability of $7,277,000 and an asset of $3,583,000, respectively. These fair values represented the estimated amount, using Level 2 observable market inputs for similar assets/liabilities, the Corporation expected to pay to terminate the Swap Agreements.
	The carrying values of the Notes due in 2008 included $1,005,000, $2,187,000 and $3,341,000 at June 30, 2008, December 31, 2007 and June 30, 2007, respectively, for the unamortized value of terminated interest rate swaps.
	Borrowings of $75,000,000 and $72,000,000 were outstanding under the commercial paper program at June 30, 2008 and December 31, 2007, respectively. No borrowings were outstanding at June 30, 2007.
	The Corporation’s Credit Agreement contains a leverage ratio covenant that requires the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve months (the “Ratio”) to not exceed 2.75 to 1.00 as of the end of any fiscal quarter. Furthermore, the covenant allows the Ratio to exclude debt incurred in connection with an acquisition for a period of 180 days, provided that the Ratio does not exceed 3.25 to 1.00. The Corporation was in compliance with the Ratio at June 30, 2008.

6. Income Taxes

	Six Months Ended June 30,
	2008			2007
Estimated effective income tax rate:
Continuing operations		29.4	%		32.3	%
Discontinued operations		40.3	%		41.2	%
Overall		30.2	%		32.4	%

The Corporation’s effective income tax rate reflects the effect of state income taxes and the impact of differences in book and tax accounting arising from the net permanent benefits associated with the depletion allowances for mineral reserves, the domestic production deduction and the tax effect of nondeductibility of goodwill related to asset sales. The effective income tax rates for discontinued operations reflect the tax effects of individual operations’ transactions and are not indicative of the Corporation’s overall effective income tax rate.

The decrease in the overall estimated effective tax rate for the six months ended June 30, 2008, as compared with the prior-year period, is primarily the result of discrete items related to effectively settling agreed upon issues from the Internal Revenue Service examination that covered the 2004 and 2005 tax years. Discrete items increased net earnings by $1,643,000, or $0.04 per diluted share, for the six months ended June 30, 2008.

The change in the year-to-date estimated overall effective income tax rate during the second quarter of 2008, when compared with the year-to-date effective tax rate as of March 31, 2008, decreased net earnings for the six months ended June 30, 2008 by $7,300,000, or $0.17 per diluted share. The first quarter 2008 effective tax rate was positively impacted by the settlement of the 2004 and 2005 tax examinations. The overall estimated effective tax rate for the six months ended June 30, 2008 is in line with management’s expectations for the full year 2008 tax rate of approximately 31.0%.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
Second Quarter and Six Months Ended June 30, 2008

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

OVERVIEW  Martin Marietta Materials, Inc. (the “Corporation”), conducts its operations through four reportable business segments: Mideast Group, Southeast Group, West Group (collectively, the “Aggregates business”) and Specialty Products. The Corporation’s net sales and earnings are predominately derived from its Aggregates business, which processes and sells granite, limestone, and other aggregates products from a network of 291 quarries, distribution facilities and plants to customers in 31 states, Canada, the Bahamas and the Caribbean Islands. The Aggregates business’ products are used primarily by commercial customers principally in domestic construction of highways and other infrastructure projects and for commercial and residential buildings. The Specialty Products segment produces magnesia-based chemicals products used in industrial, agricultural and environmental applications; dolomitic lime sold primarily to customers in the steel industry; and structural composite products.

CRITICAL ACCOUNTING POLICIES  The Corporation outlined its critical accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2007, filed with the Securities and Exchange Commission on February 25, 2008. The following presents an update to the Property, Plant and Equipment critical accounting policy:

The Corporation begins capitalizing quarry development costs at a point when reserves are determined to be proven or probable, economically mineable and when demand supports investment in the market. Capitalization of these costs ceases when production commences. Quarry development costs are classified as land improvements.

There is diversity within the mining industry regarding the accounting treatment used to record pre-production stripping costs. At existing quarries, new pits may be developed to access additional reserves. Some companies within the industry expense pre-production stripping costs associated with new pits within a quarry. In making its determination as to the appropriateness of capitalizing or expensing pre-production stripping costs, management reviews the facts and circumstances of each situation when additional pits are developed within an existing quarry. If the additional pit operates in a separate and distinct area of a quarry, the costs are capitalized as quarry development costs and depreciated over the life of the uncovered reserves. Further, a separate asset retirement obligation is created for additional pits when the liability is incurred. Once a pit enters the production phase, all post-production stripping costs are expensed as incurred as periodic inventory production costs. During the quarter ended June 30, 2008, the Corporation capitalized $1 million of quarry development costs for a new pit being created at its Three Rivers quarry in Smithland, Kentucky.

RESULTS OF OPERATIONS

Except as indicated, the following comparative analysis in the Results of Operations section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations reflects results from continuing operations and is based on net sales and cost of sales.

Gross margin as a percentage of net sales and operating margin as a percentage of net sales represent non-GAAP measures. The Corporation presents these ratios calculated based on net sales, as it is consistent with the basis by which management reviews the Corporation’s operating results. Further, management believes it is consistent with the basis by which investors analyze the Corporation’s operating results given that freight and delivery revenues and costs represent pass-throughs and have no profit mark-up. Gross margin and operating margin calculated as percentages of total revenues represent the most directly comparable financial measures calculated in accordance with generally accepted accounting principles (“GAAP”). The following tables present the calculations of gross margin and operating margin for the three and six months ended June 30, 2008 and 2007 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales (dollars in thousands):

The economic environment of the second quarter of 2008 was one of the most challenging in the aggregates industry’s history. The Corporation faced diesel fuel and natural gas costs that escalated nearly 60%, a ninth consecutive quarter of declining aggregates product line volume, and its resulting impact on operating leverage as production volumes were aligned with sales expectations. Nonetheless, the Corporation’s management team and employees did an excellent job of matching operating levels with demand and aggressively addressed controllable costs.

Net sales for the Aggregates business for the 2008 second quarter were $482.0 million, a 1.7% decline compared with 2007 second-quarter sales of $490.4 million. Heritage aggregates product line pricing increased 6.3%. Heritage aggregates product line volumes decreased 9.3% in the second quarter.

The West Group generated net sales of $191.1 million, an increase of 7.4% over the prior-year quarter. The West Group’s results were driven by a 4.4% increase in heritage aggregates product line volume resulting from the comparative strength of the infrastructure and commercial construction markets in Texas, Oklahoma and Iowa. Shipments in Iowa increased over 9% during the quarter despite severe flooding in much of the state; however, lower production levels and higher operating costs as a result of the flooding had a negative impact on profitability compared with expectations and the prior-year period. Infrastructure demand in other key states, including North Carolina and Georgia, remains challenging to forecast as rising costs of construction materials have constrained state highway budgets as well as municipal spending. Demand dropped significantly in the Mideast Group, as the usually resilient North Carolina and South Carolina markets experience the effects of residential construction declines in addition to weakening infrastructure expenditures. Several states are taking active measures to address their infrastructure funding needs; however, it is difficult to predict the impact of these measures on volume levels for the remainder of 2008.

The Aggregates business is significantly affected by seasonal changes and other weather-related conditions. Aggregates production and shipment levels coincide with general construction activity levels, most of which occurs in the spring, summer and fall. Thus, production and shipment levels vary by quarter. Operations concentrated in the northern United States generally experience more severe winter weather conditions than operations in the Southeast and Southwest. Excessive rainfall, and conversely excessive drought, can also jeopardize shipments, production and profitability. Because of the potentially significant impact of weather on the Corporation’s operations, second quarter results are not indicative of expected performance for other interim periods or the full year.

The Specialty Products segment, which includes magnesia chemicals, dolomitic lime and targeted activity in structural composites, continued to perform exceptionally well. The United States’ steel market has remained strong, leading to increased demand for dolomitic lime. The Corporation has experienced increased demand for magnesia-based chemicals products used in a number of environmental applications as well as for its flame retardant products. The Specialty Products business delivered record second-quarter net sales of $45.2 million, an increase of 13.8% compared with the prior-year quarter, and record earnings from operations of $9.7 million, an increase of 20% compared with the prior-year quarter. The business’ operating margin excluding freight and delivery revenues increased 120 basis points to 21.6% for the quarter.

The rapid and extreme increases in the cost of petroleum-based products affected both costs and sales. Liquid asphalt, used in the production of asphalt paving products, increased approximately 135% over the prior year with average prices approaching $700 per ton. The Corporation’s customers cannot react quickly enough to these escalating costs and, when possible, have made the choice to defer work in anticipation of future potential cost reductions. Cost control initiatives in place throughout the Corporation served to limit the increase in consolidated cost of sales, despite the nearly 60% increase in diesel fuel and natural gas costs compared with the prior-year quarter. The rise in the cost of petroleum-based products alone resulted in additional production costs of $18 million, or $0.26 per diluted share, for the quarter. Compounding the sharply-escalating energy costs, the Corporation incurred expenses of $24 million, or $0.35 per diluted share, to control aggregates production and reduce inventory levels.

Selling, general and administrative expenses for the quarter ended June 30, 2008 were $42.0 million versus $44.3 million in the 2007 period, a decrease of $2.3 million. The Corporation’s focus and execution on cost control decreased selling, general and administrative expenses as a percentage of net sales to 8.0% from 8.4% for the prior-year quarter.

Among other items, other operating income and expenses, net, includes gains and losses on the sale of assets; gains and losses related to certain accounts receivable; rental, royalty and services income; and the accretion and depreciation expenses related to Statement of Financial Accounting Standards No. 143,Accounting for Asset Retirement Obligations. For the second quarter, consolidated other operating income and expenses, net, was income of $7.6 million in 2008 compared with $2.8 million in 2007, primarily as a result of a $7.2 million gain on the disposals of an idle facility north of San Antonio, Texas (West Group), and land in Henderson, North Carolina (Mideast Group), in connection with the Vulcan Materials Company (“Vulcan”) exchange transaction (see also page 30).

Consolidated interest expense was $19.3 million for the second quarter 2008 as compared with $16.7 million for the prior-year quarter. The increase primarily resulted from interest for the 6.6% Senior Notes issued in April 2008, as well as other short-term borrowings.

In addition to other offsetting amounts, other nonoperating income and expenses, net, are comprised generally of interest income, net equity earnings from nonconsolidated investments and eliminations of minority interests for consolidated non-wholly owned subsidiaries. Consolidated other nonoperating income and expenses, net, for the quarter ended June 30, was expense of $1.0 million in 2008 compared with income of $1.2 million in 2007, primarily as a result of higher earnings from consolidated subsidiaries which increased the expense for the elimination of minority interests in 2008. Additionally, earnings on nonconsolidated investments were lower as compared with 2007.

Six Months Ended June 30

Notable items for the six months ended June 30, 2008 included:

• Earnings per diluted share of $2.02 compared with $2.62 for the prior-year period

• Net sales of $923.9 million, down 2% compared with the prior-year period

• Heritage aggregates product line pricing up 5.1%, volume down 8.9%

• Specialty Products earnings from operations up 21.5% from prior-year period

• Acquisition and integration of six quarry acquisitions from Vulcan Materials Company, plus two other small acquisitions

• Issuance of $300 million of Senior Notes

The following table presents net sales, gross profit, selling, general and administrative expenses and earnings (loss) from operations data for the Corporation and its reportable segments for the six months ended June 30, 2008 and 2007. In each case, the data is stated as a percentage of net sales of the Corporation or the relevant segment, as the case may be.

Earnings from operations include research and development expense and other operating income and expenses, net. Research and development expense for the Corporation was $0.3 million and $0.4 million for the six months ended June 30, 2008 and 2007, respectively. Consolidated other operating income and expenses, net, was income of $13.2 million and $5.3 million for the six months ended June 30, 2008 and 2007, respectively.

Specialty Products’ net sales were $88.1 million for the first six months of 2008 compared with $78.3 million for the prior-year period. Earnings from operations for the six months ended June 30, 2008 were $18.8 million compared with $15.5 million in the year-earlier period. Increased sales of magnesia chemical products and dolomitic lime contributed to these results.

Selling, general and administrative expenses for the six months ended June 30, 2008 were $79.7 million versus $82.6 million in the 2007 period. Selling, general and administrative expenses decreased 3.4% as the focus on cost control extended to all aspects of the business.

For the six months ended June 30, consolidated other operating income and expenses, net, was income of $13.2 million in 2008 compared with $5.3 million in 2007, primarily as a result of a $7.2 million gain on the disposals of an idle facility north of San Antonio, Texas (West Group), and land in Henderson, North Carolina (North Carolina), in connection with the Vulcan exchange transaction (see also page 30).

Consolidated interest expense was $35.1 million for the six months ended June 30, 2008 as compared with $27.9 million for the prior-year period. The increase primarily resulted from interest for the 6.6% Senior Notes issued in April 2008, as well as other short-term borrowings.

The change in the year-to-date estimated overall effective income tax rate during the second quarter of 2008, when compared with the year-to-date effective tax rate as of March 31, 2008, decreased net earnings for the six months ended June 30, 2008 by $7,300,000, or $0.17 per diluted share. The first quarter 2008 effective tax rate was positively impacted by the settlement of the 2004 and 2005 tax examinations. The overall estimated effective tax rate for the six months ended June 30, 2008 is in line with management’s expectations for the full year 2008 tax rate of approximately 31.0%.

LIQUIDITY AND CAPITAL RESOURCES  Net cash provided by operating activities during the six months ended June 30, 2008 was $125.1 million compared with $140.0 million in the comparable period of 2007. Operating cash flow is generally from net earnings, before deducting depreciation, depletion and amortization, offset by working capital requirements. Net cash provided by operating activities for the first six months of 2008 as compared with the year-earlier period reflects lower net earnings before depreciation, depletion and amortization and a higher increase in accounts receivable, partially offset by a decline in the rate of inventory build as the Corporation managed production and inventory levels and decreased tax benefits from stock option exercise activity.

The seasonal nature of the construction aggregates business impacts quarterly operating cash flow when compared with the year. Full year 2007 net cash provided by operating activities was $395.6 million, compared with $140.0 million for the first six months of 2007.

First six months capital expenditures, exclusive of acquisitions, were $159.4 million in 2008 and $115.0 million in 2007. Capital expenditures during the first six months of 2008 included work on several major plant expansion and efficiency projects. Comparable full-year capital expenditures were $264.9 million in 2007. Full-year capital spending is expected to approximate $240 million for 2008, including capital spending in connection with the Hunt Martin joint venture and exclusive of acquisitions. The Aggregates business expects its new plant in Augusta, Georgia, will begin operations in the fourth quarter of 2008 versus the prior forecast of second quarter 2009. The earlier completion of this project, which increases capacity from 2 million tons to 6 million tons annually, is expected to increase the Corporation’s market share in high-growth markets in Georgia and Florida.

During the first six months of 2008 and 2007, the Corporation paid $218.4 million and $12.1 million, respectively, for acquisitions. On April 11, 2008, the Corporation entered into a swap transaction with Vulcan, pursuant to which it acquired six quarry locations in North Georgia and Tennessee. In addition to a $192.0 million cash payment plus normal closing adjustments for working capital, the Corporation divested to Vulcan its only California quarry located in Oroville, an idle facility north of San Antonio, Texas, and land in Henderson, North Carolina, formerly leased to Vulcan. As part of the transaction, the Corporation also acquired a land parcel previously leased from Vulcan at its Three Rivers Quarry near Paducah, Kentucky. During 2008, the Corporation also acquired certain assets of the Specialty Magnesia Division of Morton International, Inc. relating to the ElastoMag^®product and a granite quarry near Asheboro, North Carolina that contains approximately 40 million tons of reserves.

The Corporation can purchase its common stock through open-market purchases pursuant to authority granted by its Board of Directors. The Corporation did not repurchase any shares of common stock during the six months ended June 30, 2008. However, $24.0 million in cash was used during January 2008 to settle common stock repurchases made as of December 31, 2007. During the six months ended June 30, 2007, the Corporation repurchased 3,585,000 shares at an aggregate cost of $495.2 million. At June 30, 2008, 5,042,000 shares of common stock were remaining under the Corporation’s repurchase authorization.

The Corporation’s five-year revolving credit agreement (the “Credit Agreement”) contains a leverage ratio covenant that requires the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve months (the “Ratio”) to not exceed 2.75 to 1.00 as of the end of any fiscal quarter. Furthermore, the covenant allows the Ratio to exclude debt incurred in connection with an acquisition for a period of 180 days, provided that the Ratio does not exceed 3.25 to 1.00. The Ratio is calculated as total long-term debt divided by consolidated EBITDA, as defined, for the trailing twelve months. Consolidated EBITDA is generally defined as earnings before interest expense, income tax expense, and depreciation, depletion and amortization expense for continuing operations. Additionally, stock-based compensation expense is added back and interest income is deducted in the calculation of consolidated EBITDA. Certain other nonrecurring items and noncash items, if they occur, can affect the calculation of consolidated EBITDA. At June 30, 2008, the Corporation’s ratio of consolidated debt to consolidated EBITDA, as defined, for the trailing twelve month EBITDA was 2.55 and was calculated as follows (dollars in thousands):

	Twelve Month Period

The management team and Board of Directors have focused on establishing prudent leverage targets that provide for value creation through strong operational performance, continued investment in internal growth opportunities, financial flexibility to support opportunistic and strategic acquisitions and a return of cash to shareholders through sustainable dividends and share repurchase programs while maintaining a solid investment grade rating. Given these parameters, in the ordinary course of business and absent any future debt incurred in connection with an acquisition, the Corporation expects to manage its leverage within a range of 2.0 to 2.5 times consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined by the underlying credit agreement. At June 30, 2008, the Corporation’s ratio of consolidated debt to consolidated EBITDA of 2.55 was outside management’s targeted range, primarily as a result of the financing for the Vulcan transaction. The Corporation plans to use available free cash flow to pay down outstanding debt balances and move within its targeted range by December 31, 2008.

On April 10, 2008, the Corporation amended its unsecured $250 million Credit Agreement to add another class of loan commitments, which had the effect of increasing the borrowing base under the agreement by $75 million. Borrowings under the Credit Agreement are unsecured and may be used for general corporate purposes, including to support the Corporation’s commercial paper program. The Credit Agreement expires on June 30, 2012.

On April 21, 2008, the Corporation completed the issuance of $300 million of 6.6% Senior Notes due in 2018 (the “6.6% Senior Notes”). The 6.6% Senior Notes, which are unsecured, may be redeemed in whole or in part prior to their maturity at a make whole redemption price. Upon a change of control repurchase event and a below investment grade credit rating, the Corporation will be required to make an offer to repurchase all outstanding 6.6% Senior Notes at a price in cash equal to 101% of the principal amount of the 6.6% Senior Notes, plus any accrued and unpaid interest to, but not including, the purchase date.

In connection with the issuance of $300 million of 6.6% Senior Notes due in 2018, on April 16, 2008, the Corporation unwound its two forward starting interest rate swap agreements with a total notional amount of $150 million (the “Swap Agreements”). The Corporation made a cash payment of $11.1 million, which represented the fair value of the Swap Agreements on the date of termination. The accumulated other comprehensive loss at the date of termination will be recognized in earnings over the life of the new Notes.

Based on prior performance and current expectations, the Corporation’s management believes that cash flows from internally generated funds and its access to capital markets are expected to continue to be sufficient to provide the capital resources necessary to fund the operating needs of its existing businesses, cover debt service requirements, and allow for payment of dividends. However, the Corporation is exposed to risk from tightening credit markets, through the interest cost related to its $225 million Floating Rate Senior Notes due in 2010 and the availability and interest cost related to its commercial paper program which is rated A-2 by Standard and Poor’s and P-2 by Moody’s. Commercial paper of $75 million was outstanding at June 30, 2008.

The Corporation may be required to obtain additional levels of financing in order to fund certain strategic acquisitions, if any such opportunities arise. Currently, the Corporation’s senior unsecured debt is rated BBB+ by Standard & Poor’s and Baa1 by Moody’s. The Corporation’s commercial paper obligations are rated A-2 by Standard & Poor’s and P-2 by Moody’s. While management believes its credit ratings will remain at an investment-grade level, no assurance can be given that these ratings will remain at those levels.

Contractual Obligations

ACCOUNTING CHANGES  As discussed in Note 1 to the Consolidated Financial Statements, effective January 1, 2008, the Corporation partially adopted FAS 157.

TRENDS AND RISKS  The Corporation outlined the risks associated with its business in its Annual Report on Form 10-K for the year ended December 31, 2007, filed with the Securities and Exchange Commission on February 25, 2008. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

During second quarter 2008, the North Carolina legislature passed a budget that provided funding for the construction of four toll road projects for a total of $3.2 billion. The first of these projects is scheduled for letting in the third quarter of 2008 with completion in 2011 and is valued at approximately $1 billion and will consume about 2 million tons of aggregates. Two additional projects will begin in 2009 and the remaining one is scheduled for 2010. These three projects are estimated to consume 4.5 million tons of aggregates. Of the total 6.5 million tons for the four projects, the Aggregates business should be fully competitive on about 85%.

Second Quarter and Six Months Ended June 30, 2008
(Continued)

OUTLOOK 2008  The Corporation’s 2008 outlook has turned decidedly more cautious in the past few months as the shock of high oil prices has affected both demand for its products and its costs. A challenging economic environment, energy inflation, credit market uncertainty and lagging infrastructure demand make forecasting increasingly difficult. Accordingly, management is adjusting downward its range for 2008 net earnings per diluted share to $5.00 to $5.65 from $6.25 to $7.00. Even in this difficult environment, management’s outlook for 2008 pricing for its Aggregates business remains positive. Accordingly, management reaffirms its 6.0% to 8.0% range for the rate of heritage aggregates price increases in 2008. Over the balance of the year, management expects infrastructure volumes in certain of the Corporation’s key states to be affected more by funding limitations than underlying demand. In addition, the sharp increase in diesel fuel prices may continue to affect infrastructure volume as customers do not have funding mechanisms to react quickly to the increases currently being experienced in liquid asphalt and other petroleum-based raw materials. However, assuming that recent downward trends in oil and commodity pricing continue, this could be a catalyst in turning demand in a positive direction. Residential construction continues to be dismal, but management still expects that large industrial commercial projects will be a plus for second-half 2008 results. As a result, the Corporation is lowering its range for 2008 heritage aggregates volumes to be down 3% to down 6%, both exclusive of acquisitions. The lime and magnesia chemicals businesses are fully expected to deliver record levels of net sales and earnings, thereby generating $36 million to $38 million in pretax earnings from Specialty Products.

The 2008 estimated earnings range includes management’s assessment of the likelihood of certain risk factors that will affect performance within the range. The most significant risk to 2008 earnings, whether within or outside current earnings expectations, continues to be the performance of the United States economy and its effect on construction activity.

Risks to the earnings range are primarily volume-related and include a greater-than-expected drop in demand as a result of the continued decline in residential construction, a decline in commercial construction, delays in infrastructure projects, or some combination thereof. Further, increased highway construction funding pressures as a result of either federal or state issues can affect profitability. Currently, North Carolina, Georgia, Texas, and South Carolina are experiencing state-level funding pressures, and these states may disproportionately affect profitability. The level of aggregates demand in the Corporation’s end-use markets, production levels and the management of production costs will affect the operating leverage of the Aggregates business and, therefore, profitability. Production costs in the aggregates business are also sensitive to energy prices, the costs of repair and supply parts, and the start-up expenses for large-scale plant projects. The continued rising cost of diesel and other fuels increases production costs either directly through consumption or indirectly through the increased cost of energy-related consumables, namely steel, explosives, tires and conveyor belts. Sustained periods of diesel fuel cost at the current level will continue to have a negative impact on profitability. The availability of transportation in the Corporation’s long-haul network, particularly the availability of barges on the

Mississippi River system and the availability of rail cars and locomotive power to move trains, affects the Corporation’s ability to efficiently transport material into certain markets, most notably Texas and the Gulf Coast region. The Aggregates business is also subject to weather-related risks that can significantly affect production schedules and profitability. Hurricane activity in the Atlantic Ocean and Gulf Coast generally is most active during the third and fourth quarters. Opportunities to reach the upper end of the earnings range depend on the aggregates product line demand exceeding expectations.

Risks to earnings outside of the range include a change in volume beyond current expectations as a result of economic events outside of the Corporation’s control. In addition to the impact of residential and commercial construction, the Corporation is exposed to risk in its earnings expectations from tightening credit markets and the availability of and interest cost related to its commercial paper program, which is rated A-2 by Standards & Poor’s and P-2 by Moody’s. Commercial paper of $75 million was outstanding at June 30, 2008.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

The Corporation’s operations are highly dependent upon the interest rate-sensitive construction and steelmaking industries. Consequently, these marketplaces could experience lower levels of economic activity in an environment of rising interest rates or escalating costs.

The current credit environment has negatively affected the economy and management has considered the potential impact to the Corporation’s business. Demand for aggregates products, particularly in the commercial and residential construction markets, could continue to decline if companies and consumers are unable to obtain financing for construction projects or if the economic slowdown causes delays or cancellations to capital projects. Additionally, the Corporation may experience difficulty placing its A-2/P-2 commercial paper.

Demand in the residential construction market is affected by interest rates. Since December 31, 2007, the Federal Reserve Board cut the federal funds rate by 225 basis points to 2.0% in April, 2008. In addition to other factors that contributed to the rate cut, the Federal Open Market Committee stated that it saw a deepening of the housing contraction. The residential construction market accounted for approximately 12% of the Corporation’s aggregates product line shipments in 2007.

Aside from these inherent risks from within its operations, the Corporation’s earnings are affected also by changes in short-term interest rates, as a result of any temporary cash investments, including money market funds and overnight investments in Eurodollars; any outstanding commercial paper obligations; Floating Rate Senior Notes; defined benefit pension plans; and petroleum-based product costs.

Commercial Paper Obligations.The Corporation has a $325 million commercial paper program in which borrowings bear interest at a variable rate based on LIBOR. At June 30, 2008, commercial paper borrowings of $75 million were outstanding. As commercial paper borrowings bear interest at a variable rate, the Corporation has interest rate risk. The effect of a hypothetical 100-basis-point increase in interest rates on commercial paper borrowings of $75 million would increase interest expense by $0.8 million on an annual basis.

Floating Rate Senior Notes.The Corporation has $225 million of Floating Rate Senior Notes that bear interest at a rate equal to the three-month LIBOR plus 0.15%. As the Floating Rate Senior Notes bear interest at a variable rate, the Corporation has interest rate risk. The effect of a hypothetical 100 basis point increase in interest rates on borrowings of $225 million would increase interest expense by $2.3 million on an annual basis.

FORM 10-Q
For the Quarter Ended June 30, 2008

Pension Expense.The Corporation’s results of operations are affected by its pension expense. Assumptions that affect this expense include the discount rate and the expected long-term rate of return on assets. Therefore, the Corporation has interest rate risk associated with these factors. The impact of hypothetical changes in these assumptions on the Corporation’s annual pension expense is discussed in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2007, filed with the Securities and Exchange Commission on February 25, 2008.

Petroleum-Based Product Costs. Petroleum-based product costs, including diesel fuel, natural gas and liquid asphalt, represent significant production costs for the Corporation. Increases in these costs generally are tied to energy sector inflation. For the six months ended June 30, 2008, increases in these costs lowered net earnings by $0.39 per diluted share when compared with 2007.

Aggregate Risk for Interest Rates and Petroleum-Based Product Sector Inflation.The pension expense for 2008 is calculated based on assumptions selected at December 31, 2007. Therefore, interest rate risk in 2008 is limited to the potential effect related to outstanding commercial paper and the Corporation’s Floating Rate Senior Notes. Assuming outstanding commercial paper of $75 million and Floating Rate Senior Notes of $225 million, the impact of a hypothetical 100 basis point increase in interest rates would increase interest expense and decrease pretax earnings by $3.0 million. Additionally, increases in petroleum-based product costs have already had a significant impact on year-to-date 2008 pretax earnings.

Item 4. Controls and Procedures

As of June 30, 2008, an evaluation was performed under the supervision and with the participation of the Corporation’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and the operation of the Corporation’s disclosure controls and procedures. Based on that evaluation, the Corporation’s management, including the Chief Executive Officer and Chief Financial Officer, concluded that the Corporation’s disclosure controls and procedures were effective as of June 30, 2008. There have been no significant changes in the Corporation’s internal controls or in other factors that could significantly affect the internal controls subsequent to June 30, 2008.
