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, 2006, filed with the Securities and Exchange Commission on February 28, 2007. 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 for the interim periods. The results of operations for the six months ended June 30, 2007 are not indicative of the results expected for the full year.

Retirement Plans and Postretirement Benefits

On December 31, 2006, the Corporation adopted the recognition and disclosure provisions of Statement of Financial Accounting Standards No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an Amendment of FAS 87, 88, 106 and 132(R) (“FAS 158”) prospectively. In connection with the adoption, the Corporation increased accumulated other comprehensive loss by $20,418,000, net of tax, at December 31, 2006 for the net unrecognized actuarial losses, unrecognized prior service costs and unrecognized transition obligations remaining from the initial adoption of FAS 87 and FAS 106. During the six months ended June 30, 2007, $1,137,000, net of tax, of these unrecognized amounts was recognized as a component of net periodic benefit cost pursuant to the Corporation’s historical accounting policy for amortizing such amounts.

Uncertain Tax Positions

Effective January 1, 2007, the Corporation adopted Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FAS 109 (“FIN 48”). FIN 48 requires the recognition of a tax benefit when it is “more-likely-than-not,” based on the technical merits, that the position would be sustained upon examination by a taxing authority. The amount to be recognized should be measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information.

1. Significant Accounting Policies (continued)

Uncertain Tax Positions (continued)

In connection with the adoption of FIN 48, the Corporation increased its reserves for uncertain tax positions and reduced retained earnings at January 1, 2007 by $1,407,000, primarily as a result of providing interest accruals on uncertain temporary tax positions related to temporary or timing differences.

The adoption of FIN 48 affected the Corporation’s results of operations as follows:

	Three Months Ended		Six Months Ended
	June 30, 2007		June 30, 2007
Increased income tax expense and decreased net earnings by:	$	539,000	$	1,431,000
Decreased basic earnings per share by:	$	0.01	$	0.03
Decreased diluted earnings per share by:	$	0.01	$	0.03

At January 1, 2007, the total amount of gross unrecognized tax benefits, excluding interest, was $29,248,000. Unrecognized tax benefits of $10,577,000, net of federal tax benefits, related to interest accruals and permanent income tax differences would favorably affect the Corporation’s effective tax rate if recognized. There have been no significant changes to these amounts during the six months ended June 30, 2007.

The Corporation anticipates that it is reasonably possible that the total amounts of unrecognized tax benefits may significantly change within the succeeding twelve months as a result of the expiration of the federal statute of limitations for examination of the 2003 tax year and the settlement of the Internal Revenue Service audits for the 2004 and 2005 tax years. The Corporation estimates that these events could result in a reasonably possible change in unrecognized tax benefits ranging from $8,278,000 to $27,772,000.

The Corporation records interest accrued in relation to unrecognized tax benefits as income tax expense and penalties, if incurred, are recorded as operating expenses in the consolidated statement of earnings. Accrued interest of $6,081,000 was recorded as a current FIN 48 liability in the Corporation’s consolidated balance sheet at June 30, 2007.

The Corporation’s open tax years that are subject to examination are 2003 through 2006. The Internal Revenue Service is currently auditing the Corporation’s consolidated federal income tax returns for the years ended December 31, 2005 and 2004.

Comprehensive Earnings

Comprehensive earnings for the three and six months ended June 30, 2007 were $88,601,000 and $122,419,000, respectively, and consisted of net earnings, foreign currency translation adjustments, changes in the fair value of forward starting interest rate swap agreements and the amortization of unrecognized amounts related to pension and postretirement benefits. For the three and six month periods ended June 30, 2006, comprehensive earnings did not differ from net earnings.

2. Divestitures and Discontinued Operations

In 2007, the Corporation disposed of or permanently shut down certain underperforming operations in the following markets:

Reportable Segment	Markets
Mideast Group	West Virginia

On April 25, 2007, the Corporation issued $250,000,000 of 6.25% Senior Notes due in 2037 and $225,000,000 of Floating Rate Senior Notes due in 2010 (collectively, the “Senior Notes”). The 6.25% Senior Notes may be redeemed in whole or in part prior to their maturity at a “make whole” redemption price. The Floating Rate Senior Notes bear interest at a rate equal to the three-month LIBOR (5.355% at June 30, 2007) plus 0.15% and may not be redeemed prior to maturity. Upon a change of control repurchase event, the Corporation will be required to make an offer to repurchase all outstanding Senior Notes at a price in cash equal to 101% of the principal amount of the Senior Notes, plus any accrued and unpaid interest to, but not including, the purchase date.

The carrying values of the Notes due in 2008 included $3,341,000, $4,469,000 and $5,570,000 at June 30, 2007, December 31, 2006 and June 30, 2006, respectively, for the unamortized value of terminated interest rate swaps.

The Corporation entered into two forward starting interest rate swap agreements in September 2006 related to $150,000,000 of the Corporation’s anticipated refinancing of its $200,000,000 5.875% Notes due in 2008 (the “Swap Agreements”). At June 30, 2007, the fair value of the Swap Agreements was an asset of $3,583,000 and was included in other noncurrent assets in the Corporation’s consolidated balance sheet. Other comprehensive earnings/loss for the three and six months ended June 30, 2007 included a gain of $3,143,000 and $3,345,000, respectively, net of tax, for the change in fair value of the Swap Agreements. At December 31, 2006, the fair value of the Swap Agreements was a liability of $1,951,000.

5. Long-Term Debt (continued)

No commercial paper borrowings were outstanding at June 30, 2007 and December 31, 2006. Borrowings of $10,000,000 were outstanding under the commercial paper program at June 30, 2006.

At December 31, 2006 and June 30, 2006, borrowings of $537,000 and $3,539,000, respectively, were outstanding under a $10,000,000 line of credit. No such borrowings were outstanding at June 30, 2007.

On April 17, 2007, the Corporation entered into an amendment of its $250,000,000 five-year revolving credit agreement, which modified the leverage ratio covenant in the agreement. As modified, the covenant 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 to not exceed 2.75 to 1.00 as of the end of any fiscal quarter. The covenant has certain exceptions related to qualifying acquisitions, as defined.

6. Income Taxes

	Six Months Ended June 30,
	2007			2006
Estimated effective income tax rate:
Continuing operations		32.3	%		31.2	%
Discontinued operations		41.6	%		41.1	%
Overall		32.4	%		31.3	%

The Corporation’s effective 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 tax rate.

The increase in the Corporation’s effective tax rate for continuing operations for the six months ended June 30, 2007 as compared with the prior-year period results from the discrete tax impact of stock option exercises during the period, tax on certain foreign source income and the effect of applying FIN 48. The effective income tax rate increased 75 basis points during the first six months of 2007 as a result of the evaluation of the Corporation’s tax positions in accordance with FIN 48.

The change in the year-to-date estimated overall effective income tax rate during the second quarter of 2007, when compared with the year-to-date effective tax rate as of March 31, 2007, increased net earnings for the six months ended June 30, 2007 by $2,400,000, or $0.05 per diluted share.

9. Business Segments

In the fourth quarter of 2006, the Corporation reorganized the operations and management of its Aggregates business, which resulted in a change to its reportable segments. Currently, the Corporation conducts its aggregates operations through three reportable business segments: Mideast Group, Southeast Group and West Group. The Corporation also has a Specialty Products segment that includes magnesia chemicals, dolomitic lime and targeted activity in structural composites.

The following tables display selected financial data for the Corporation’s reportable business segments (dollars in thousands). Corporate loss from operations primarily includes depreciation on capitalized interest, expenses for corporate administrative functions, unallocated corporate expenses and other nonrecurring and/or non-operational adjustments. Prior year information has been reclassified to conform to the presentation of the Corporation’s current reportable segments.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
Second Quarter and Six Months Ended June 30, 2007

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 306 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, 2006, filed with the Securities and Exchange Commission on February 28, 2007.

Prior to the three months ended June 30, 2007, the Corporation valued its finished goods inventories using standards that were updated annually during the fourth quarter. During the three months ended June 30, 2007, the Corporation recorded a $9.0 million inventory valuation adjustment to reflect increasing production costs and transportation costs to distribution yards. The adjustment, which increased the carrying value of inventories and reduced cost of sales, increased quarterly net earnings by $5.5 million, or $0.13 per diluted share.

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, 2007 and 2006 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales (dollars in thousands):

Net sales for the Aggregates business for the 2007 second quarter were $494.9 million, a 3.0% increase over 2006 second-quarter sales of $480.3 million. Aggregates pricing at heritage locations was up 13.3%, while volume decreased 9.0%. Inclusive of acquisitions and divestitures, aggregates pricing for the quarter increased 13.1% and aggregates product line volume decreased 9.0%. Pricing improvements continued to hold in the Aggregates business in spite of greater than expected volume declines. During the quarter, the level of residential construction spending in the United States reached its lowest point since April 2004 as reported by the U.S. Census Bureau. Although residential construction contributed only 17% of the Corporation’s aggregates product line shipments in 2006, sales into this end-use sector have diminished in virtually every market. In addition, commercial construction activity in the South Central United States’ markets, notably, Alabama, Mississippi and Tennessee, is weak.

Weather also plagued performance during the second quarter. The West Group, particularly Texas, southern Oklahoma and Kansas, experienced near historic levels of rainfall and flooding which affected both shipments and operations. Volumes declined 9.4% in these areas and negatively contributed to financial performance during the quarter. Management does not believe that any significant construction projects have been permanently delayed and expects the volume for commercial and infrastructure to return to expected levels when weather conditions normalize.

(1)	Volume/pricing variances reflect the percentage increase/(decrease) from the comparable period in the prior year.
(2)	Heritage Aggregates product line excludes acquisitions that have not been included in prior-year operations for the comparable period and divestitures.
(3)	Aggregates Business includes all acquisitions from the date of acquisition and divestitures through the date of disposal.
(4)	Divestitures include the tons related to divested operations up to the date of divestiture.

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. Furthermore, excessive rainfall 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 the year.

Second-quarter results for the Specialty Products segment, which includes magnesia chemicals, dolomitic lime and targeted activity in structural composites, were positive. Specialty Products’ net sales were $39.7 million for the second quarter 2007 compared with $36.4 million for the prior-year period. Earnings from operations for the quarter were $8.1 million compared with $7.1 million in the year-earlier period. Management has established specific quarterly benchmarks for 2007 to evaluate the viability of the remaining components of the structural composites product line.

Selling, general and administrative expenses for the quarter ended June 30, 2007 was $44.3 million versus $37.1 million in the 2006 period. This increase of $7.2 million was primarily related to a $5.3 million increase in performance-based incentive compensation.

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 $3.1 million in 2007 compared with $3.6 million in 2006, primarily as a result of higher gains on the sales of assets in 2006.

During the quarter, the Corporation revised its finished goods inventory valuation standards to match finished goods inventory values with the significant escalation in cost, particularly related to the transportation of material to distribution yards. Historically, the Corporation has updated inventory standards once a year in the fourth quarter. However, given the magnitude of the cost change and since the Corporation’s inventory turns about once a quarter, this revaluation, which increased inventory values by $9.0 million, more closely approximates cost of sales. Management will continue to review its inventory standards on an ongoing basis.

Consolidated interest expense was $16.7 million for the second quarter 2007 as compared with $9.7 million for the prior-year quarter. The increase primarily resulted from the accrual of $4.7 million of interest for the 6.25% Senior Notes and Floating Rate Senior Notes issued in April 2007 and a lower amount of capitalized interest related to major plant expansion and efficiency projects in 2007 as compared with the prior-year quarter.

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 income of $1.2 million in 2007 compared with $0.3 million in 2006, primarily as a result of higher interest income in 2007.

Selling, general and administrative expenses for the six months ended June 30, 2007 was $82.6 million versus $73.3 million in the 2006 period. This increase of $9.3 million was primarily related to a $6.9 million increase in performance-based incentive compensation.

For the six months ended June 30, other operating income and expenses, net, was income of $5.6 million in 2007 compared with $7.2 million in 2006, primarily as a result of income from a $2.1 million judgment in favor of the Corporation in a land condemnation and higher gains on the sales of assets in 2006. These were partially offset by a higher gain on receivables in 2007.

Consolidated interest expense was $27.9 million for the six months ended June 30, 2007 compared with $19.7 million for the prior-year period. The increase resulted from the accrual of $4.7 million of interest for the 6.25% Senior Notes and Floating Rate Senior Notes issued in April 2007 and a lower amount of capitalized interest related to major plant expansion and efficiency projects in 2007 as compared with the prior-year period.

LIQUIDITY AND CAPITAL RESOURCES Net cash provided by operating activities during the six months ended June 30, 2007 was $140.0 million compared with $113.9 million in the comparable period of 2006. 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 2007 as compared with the year-earlier period reflects higher earnings, a higher accrual for income tax obligations and a lower increase in accounts receivable in 2007 resulting from better collection results, and was partially offset by a higher build up of inventories due to declining shipment volumes and increased tax benefits from stock option exercise activity.

Depreciation, depletion and amortization was as follows (amounts in millions):

	Six Months Ended
	June 30,
	2007		2006
Depreciation	$	69.8	$	62.4
Depletion		2.1		2.2
Amortization		1.5		2.0
	$	73.4	$	66.6

The increase in depreciation expense is primarily due to the completion of several large capital projects, including new plants at the Three Rivers operations in Kentucky and North Troy operations in Oklahoma.

The seasonal nature of the construction aggregates business impacts quarterly operating cash flow when compared with the year. Full year 2006 net cash provided by operating activities was $338.2 million, compared with $113.9 million for the first six months of 2006.

First six months capital expenditures, exclusive of acquisitions, were $115.0 million in 2007 and $157.7 million in 2006. Capital expenditures during the first six months of 2006 included work on several major plant expansion and efficiency projects. Comparable full-year capital expenditures were $266.0 million in 2006. Full-year capital spending is expected to approximate $235.0 million for 2007, including the Hunt Martin joint venture and exclusive of acquisitions. Additionally, in 2007, the Corporation expects to enter into a lease agreement for 50 barges with a total commitment of approximately $24.0 million.

During the first six months of 2006, the Corporation received repayment of a $12.5 million note receivable related to the divestiture of its Houston asphalt operations. The Corporation continues to have a continuing financial interest in the Houston asphalt market via a supply agreement and therefore continues to include the divested locations in continuing operations.

During 2007, the Corporation continued its common stock repurchase plan through open-market purchases pursuant to authority granted by its Board of Directors. For the quarter ended June 30, 2007, the Corporation repurchased 1,250,000 shares at an aggregate cost of $193.2 million. During the six months ended June 30, the Corporation repurchased 3,585,000 shares at an aggregate cost of $495.2 million in 2007 compared with 914,400 shares at an aggregate cost of $83.2 million in 2006. At June 30, 2007, 646,000 shares of common stock were remaining under the Corporation’s repurchase authorization. The Corporation currently intends to review its share repurchase authorization.

The Corporation’s $125 million 6.9% Notes will mature in August 2007. Management currently intends to refinance the 6.9% Notes using the proceeds from the Corporation’s offering of public debt in April 2007. Those proceeds were utilized on an interim basis to repay short-term commercial paper incurred for common stock repurchases during the first quarter of 2007. Therefore, the Corporation will issue new commercial paper debt upon refinancing the 6.9% Notes.

In September 2006, the Corporation entered into two forward starting interest rate swap agreements (the “Swap Agreements”) related to $150 million of the Corporation’s anticipated refinancing of its $200 million 5.875% Notes due in 2008. The change in fair value of the Swap Agreements, net of income taxes, is recorded directly in shareholders’ equity as other comprehensive earnings/loss. At June 30, 2007, the fair value of the Swap Agreements was an asset of $3.6 million and was included in other noncurrent assets in the Corporation’s consolidated balance sheet. Other comprehensive earnings/loss for the six months ended June 30, 2007 included a gain of $3.3 million, net of tax, for the change in fair value of the Swap Agreements.

On April 17, 2007, the Corporation entered into an amendment of its $250 million five-year revolving credit agreement, which modified the leverage ratio covenant in the agreement. As modified, the covenant 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 to not exceed 2.75 to 1.00 as of the end of any fiscal quarter. The covenant has certain exceptions related to qualifying acquisitions, as defined. At June 30, 2007, the Corporation’s ratio of consolidated debt to consolidated EBITDA, as defined, was 2.03.

On April 25, 2007, the Corporation issued $250 million of 6.25% Senior Notes due in 2037 and $225 million of Floating Rate Senior Notes due in 2010 (collectively, the “Senior Notes”). The 6.25% Senior Notes may be redeemed in whole or in part prior to their maturity at a “make whole” redemption price. The Floating Rate Senior Notes bear interest at a rate equal to the three-month LIBOR plus 0.15% and may not be redeemed prior to maturity. Upon a change of control repurchase event, the Corporation will be required to make an offer to repurchase all outstanding Senior Notes at a price in cash equal to 101% of the principal amount of the Senior Notes, plus any accrued and unpaid interest to, but not including, the purchase date.

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, 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.

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 in 2007.

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

Upon adoption of FIN 48 at January 1, 2007, the Corporation had gross unrecognized tax benefits, excluding interest, of $29.2 million. The Corporation anticipates settlement of $27.8 million with the taxing authorities in the upcoming twelve months and settlement of $1.4 million in one to three years.

ACCOUNTING CHANGES As discussed in Note 1 to the Consolidated Financial Statements, effective January 1, 2007, the Corporation adopted FIN 48 and reduced retained earnings by $1.4 million.

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, 2006, filed with the Securities and Exchange Commission on February 28, 2007. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

In July 2007, the state of North Carolina approved the issuance of $300 million of Grant Anticipation Revenue vehicles, or GARVEE bonds, to fund various road projects statewide. The bonds will be repaid with federal money the state expects to receive for highway and interstate projects in future years. Management currently expects construction to begin on these projects in 2008.

OUTLOOK 2007 Based upon the Corporation’s strong first-half 2007 performance, management continues to have a positive outlook on the remainder of the year. Aggregates product line pricing is expected to increase 11% to 12% for the year, which is higher than earlier guidance. However, aggregates shipments are more difficult to estimate for the balance of the year. Management currently expects volume to decrease 4% to 6% for the year with the degree of decline predicated on a longer-than-expected correction in the residential construction market, in addition to commercial construction weakness in the Mississippi River markets. The Specialty Products segment, which includes magnesia chemicals, dolomitic lime and focused activity in structural composites, is expected to contribute $33 million to $36 million in pretax earnings in 2007 compared with $22 million in 2006. Management expects the magnesia chemicals business to continue to grow and demand for dolomitic lime from the steel industry to be flat or down slightly.

With this backdrop, management currently expects net earnings per diluted share for the third quarter to range from $1.95 to $2.25 and the range for the year is $6.15 to $6.65. In the third quarter, the overall effective tax rate is expected to be below 30%, which will bring the higher rate of the first two quarters in line with management’s 32% expectation for the year.

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. Since June 30, 2004, the Federal Reserve Board has increased the federal funds rate from 1.00% to 5.25% at June 30, 2007. This increase has affected the residential construction market, which accounted for approximately 17% of the Corporation’s aggregates product line shipments in 2006. 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 its 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 energy costs. Additionally, the shareholders’ equity of the Corporation is affected by changes in the fair value of forward starting interest rate swap agreements.

Commercial Paper Obligations. The Corporation has a $250 million commercial paper program in which borrowings bear interest at a variable rate based on LIBOR. At June 30, 2007, there were no commercial paper borrowings outstanding. As commercial paper borrowings bear interest at a variable rate, the Corporation has interest rate risk when such debt is outstanding.

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.

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, 2006, filed with the Securities and Exchange Commission on February 28, 2007.

Energy Costs. Energy 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. In 2006, energy costs increased significantly, with fuel price increases lowering earnings per diluted share by $0.36. A hypothetical 10% change in the Corporation’s energy prices in 2007 as compared with 2006, assuming constant volumes, would impact 2007 pretax earnings by approximately $17.8 million.

For the Quarter Ended June 30, 2007

Aggregate Risk for Interest Rates and Energy Sector Inflation. The pension expense for 2007 is calculated based on assumptions selected at December 31, 2006. Therefore, interest rate risk in 2007 is limited to the potential effect related to outstanding commercial paper, none of which is currently outstanding, and the Corporation’s Floating Rate Senior Notes. Assuming outstanding 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 $2.3 million. Additionally, a 10% change in energy costs would impact annual pretax earnings by $17.8 million.

Forward Starting Interest Rate Swap Agreements. In September 2006, the Corporation entered into forward starting interest rate swap agreements (the “Swap Agreements”) for the anticipated refinancing of $150.0 million of its $200.0 million 5.875% Notes due in 2008. In accordance with Statement of Financial Accounting Standards No. 133 Accounting for Derivative Instruments and Hedging Activities (“FAS 133”), the fair values of the Swap Agreements are recorded as an asset or liability in the consolidated balance sheet. The change in fair value is recorded directly in shareholders’ equity, net of taxes, as other comprehensive earnings/loss. At June 30, 2007, the fair value of the Swap Agreements was an asset of $3.6 million and was included in other noncurrent assets in the Corporation’s consolidated balance sheet.

As a result of the Swap Agreements, the Corporation’s comprehensive earnings/loss will be affected by changes in the LIBOR rate. A hypothetical change in interest rates of 100 basis points would change other comprehensive earnings/loss by approximately $9 million, which is net of taxes of $6 million.

Item 4. Controls and Procedures

As of June 30, 2007, 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, 2007. 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, 2007.

MARTIN MARIETTA MATERIALS, INC.
AMENDED AND RESTATED EXECUTIVE INCENTIVE PLAN

I. PURPOSE

The purpose of the Martin Marietta Materials, Inc. Executive Incentive Plan (the “Plan”) is to enhance profits and overall performance by providing for its key management an additional inducement for achieving and exceeding Martin Marietta Materials, Inc. (“MMM” or the “Corporation”) performance objectives. Additionally, the Plan will allow a level of compensation that is appropriate when compared with compensation levels of other comparable organizations.

II. STANDARD OF CONDUCT AND PERFORMANCE EXPECTATION

A.

It is expected that the business and individual goals and objectives established for this Plan will be accomplished in accordance with the Corporation’s policy on ethical conduct in business. It is a prerequisite before any award can be considered that a participant will have acted in accordance with the Martin Marietta Materials, Inc. Code of Ethics and Standards of Conduct and fostered an atmosphere to encourage all employees acting under the participant’s supervision to perform their duties in accordance with the highest ethical standards. Ethical behavior is imperative. Thus, in achieving one’s goals, the individual’s commitment and adherence to the Corporation’s ethical standards will be considered paramount in determining awards under this Plan.

B.

Plan participants whose individual performance is determined to be less than acceptable are not eligible to receive incentive awards.

III. EFFECTIVE DATE

The Plan will become effective each year commencing January 1.

IV. BASIC PROGRAM ELIGIBILITY

Subject to the discretion of the Chief Executive Officer of the Corporation, an employee will be eligible to participate in the Plan for any Plan year in which the employee is classified no later than July 1 of that year as one of the following:

President
Vice President
General Manager
Director
Others recommended by a Corporate Officer

A Corporate Officer is any elected officer of the Corporation.

V. BASIS FOR AWARDS

Awards will be paid based on the actual base salary paid to each participant during each Plan year, and will be determined based on the following criteria:

A.	Responsibility	Target Incentive Award
	Level	(% of Annual Salary)
	Chief Operating Officer	80-100%
	Division Presidents	60%-80%
	Designated VPs of major functions	60%-80%

	or Chief Executive Officer
	(Corporate Unit Head)
	Vice President/General Manager	40%-50%
	reporting to a Division President or
	Corporate Unit Head
	Designated Directors/General Managers/	30%-50%
	Vice Presidents
	Other Directors/Managers	30%-35%

The award percentages noted above may be adjusted up or down subject to the discretion of the Chief Executive Officer of the Corporation.

B. Available Award

Total incentive awards will be based on a combination of the performance of MMM, the Operating Unit (as defined below), the Corporate Unit (as defined below) and the individual, depending on the position occupied by the participant and other factors described below. An “Operating Unit” is an operating unit(s) of the Corporation for which the individual is responsible (for example, one or more segments, divisions, regions, districts, etc.) as designated by the Chief Executive Officer. A “Corporate Unit” is a non-operating unit(s) of the Corporation for which the individual is responsible (for example, one or more of finance, legal, marketing, purchasing, etc.) as designated by the Chief Executive Officer. The portion of the total award determined by the performance of MMM, the Operating Unit, the Corporate Unit and the individual is outlined below.

1. Operating Units

For Division Presidents, participants reporting to Division Presidents, and participants whose work is primarily related to an Operating Unit, the award will be based on the following:

	Operating Unit			Division			MMM			Individual
	Performance			Performance			Performance			Performance
Divisions
Line Management		50	%		—			25	%		25	%
Staff		37.5	%		—			25	%		37.5	%
Areas, Districts & Regions
Line Management		50	%		12.5	%		12.5	%		25	%
Staff		37.5	%		12.5	%		12.5	%		37.5	%

2. Corporate Units

For individuals reporting to the Chief Executive Officer who are responsible for a Corporate Unit and are not in an Operating Unit (“Corporate Unit head”), participants reporting to a Corporate Unit head, and participants whose work is primarily related to the Corporation, the award will be based on the following:

• Fifty percent (50%) of the award will be based on MMM performance, as defined in Paragraph V.C.1 below.

• Fifty percent (50%) of the award will be based on individual performance, as defined in Paragraph V.C.2 above.

3. Combined Responsibilities

For individuals who have responsibilities described in both Paragraphs V.B.1 and V.B.2 above, the award will be based on the following:

• Sixty-five percent (65%) of the award will be based on the performance of MMM and the Operating Unit(s) which that individual is responsible, as defined in Paragraph V.C.1 below.

• Thirty-five percent (35%) of the award will be based on individual performance, as defined in Paragraph V.C.2 below.

C. Performance Criteria

1. MMM, Operating Units and Corporate Units

MMM, Operating Unit and Corporate Unit performance will be measured by profit contribution, cash flow, sales and production metrics and/or other appropriate financial performance, return, safety and other factors reflecting the performance of the Corporation, Operating Unit and Corporate Unit.

The Management Development and Compensation Committee of the Board of Directors will determine the percentage that was achieved by MMM and the Chief Executive Officer of the Corporation will determine the percentage that was achieved by the Operating Units and the Corporate Units, each based on an assessment of the factors listed above and on a subjective evaluation of the overall contribution to the Corporation and will apply that percentage to the portion of the total award that is available for MMM, the Operating Unit(s) and/or the Corporate Unit(s) as outlined in Paragraph V.B. above.

2. Individual Performance

The portion of the total award based on individual performance, if applicable, will be based on an assessment of the actual achievement of the individual relative to quantitative, measurable goals established for the Plan year, conduct in accordance with the Corporation’s Code of Ethics and Standards of Conduct and a subjective evaluation of the relative significance of one’s efforts in respect to its bearing on the overall Corporation, Operating Unit(s) and/or Corporate Unit(s).

The Chief Executive Officer will determine the percentage that was achieved by the individual based on an assessment of the factors listed above and on a subjective evaluation of the overall contribution of the individual, and will apply that percentage to the portion of the total award that is available for the individual, as outlined in Paragraph V.B. above.

D. Discretion of the Chief Executive Officer

Subject to approval by the Management Development and Compensation Committee of the Board of Directors, the Chief Executive Officer of the Corporation may modify the percentage of available award for any or all of the MMM, Operating Unit, Corporate Unit and/or individual awards, based on an assessment of organizational and/or individual contribution. The participant’s individual performance may impact the percent of available MMM, Operating Unit and/or Corporate Unit award. The performance of MMM, the Operating Unit and/or Corporate Unit may impact the percent of available individual award.

E. Payment of Awards

Awards under the Plan shall be payable in a lump sum, excluding the amounts, if any, credited on an elective or non-elective basis to stock units pursuant to the Martin Marietta Materials, Inc. Incentive Stock Plan, as soon as practicable following the close of the Plan year.

F. Changes in Participation

An employee must be a full-time employee of the Corporation on December 31 of the Plan Year to be eligible to participate in the Plan. It is recognized that during a Plan year, individual changes in the eligibility group may occur as participants change jobs or terminate through death, retirement or other reasons. As these circumstances occur, the Chief Executive Officer of the Corporation may, in his discretion, give consideration to recommend the grant of the award under the Plan and/or to adjust the amount of incentive award paid.

Persons in the eligibility group hired during a Plan year may be eligible for an award under the Plan in that year at the discretion and approval of the Chief Executive Officer.
