NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED)

Basis of Presentation

The accompanying unaudited, interim condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and, in management’s opinion, contain all adjustments (consisting of normal recurring items) necessary for a fair presentation, in all material respects, of the financial position and results of operations for the periods presented. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.

The preparation of condensed financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The results of operations for the interim period ended March 31, 2010 are not necessarily indicative of the results that may be expected for subsequent quarterly periods or the year ending December 31, 2010.

The condensed financial statements should be read in conjunction with the financial statements and related footnotes, which appear in our Annual Report on Form 10-K for the year ended December 31, 2009.

There have been no significant changes in the accounting principles and policies, long-term contracts or estimates inherent in the preparation of the condensed financial statements of Old Dominion Freight Line, Inc. as previously described in our Annual Report on Form 10-K for the year ended December 31, 2009, other than the changes to certain estimated useful lives and salvage values in our property and equipment policy described in this quarterly report.

Unless the context requires otherwise, references in these Notes to “Old Dominion,” the “Company,” “we,” “us” and “our” refer to Old Dominion Freight Line, Inc.

Property and Equipment

Property and equipment are stated at cost. Major additions and improvements are capitalized, while maintenance and repairs that do not improve or extend the lives of the respective assets are charged to expense as incurred. We capitalize the cost of tires mounted on purchased revenue equipment as a part of the total equipment cost. Subsequent replacement tires are expensed at the time those tires are placed in service.

Depreciation of property and equipment is calculated using the straight-line method over the estimated useful lives of the related assets. The following table provides the estimated useful lives by asset type:

During the first quarter of 2010, we completed an evaluation of the estimated useful lives and salvage values for our equipment and determined that the actual period of service of certain revenue equipment and other equipment exceeded that of our previously estimated useful lives. As a result, we extended the estimated useful lives of most of our tractors to 9 years from 7 years and extended the estimated useful lives of our trailers to 15 years from 12 years. In addition, we reduced the estimated salvage values

NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

associated with this equipment to more accurately reflect the value we believe such equipment will have at the end of its respective useful life. We made similar changes to the estimated useful lives and salvage values for certain of our other equipment, but the results of these changes have less of an impact on our future depreciation expense. As a result of the impact on depreciation from these changes that were effective January 1, 2010, income from continuing operations increased by approximately $2.1 million and net income increased by approximately $1.3 million, or $0.03 per diluted share for the first quarter of 2010. We expect the results of these changes to increase income from continuing operations and net income in 2010 by approximately $12.7 million and $7.6 million, or $0.20 per diluted share, respectively.

Fair Values of Financial Instruments

At March 31, 2010 and December 31, 2009, the carrying values of financial instruments, such as cash and cash equivalents, customer and other receivables and trade payables, approximates their fair value due to the short maturities of these instruments. The cash surrender value relating to Company-owned life insurance contracts is included in “Other assets” on our Balance Sheets and totaled $19.7 million and $17.9 million at March 31, 2010 and December 31, 2009, respectively, which approximates fair value as determined by quoted market prices. The fair value of the senior notes included in our long-term debt was estimated to be $229.0 million and $238.6 million at March 31, 2010 and December 31, 2009, respectively. The fair value of these senior notes is based on discounted cash flows at market interest rates for similar issues of private debt.

Earnings Per Share

Earnings per common share is computed using the weighted average number of common shares outstanding during the period.

Recent Accounting Pronouncements

In January 2010, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2010-6, Improving Disclosures About Fair Value Measurements , which clarifies certain existing disclosure requirements and requires additional disclosures for recurring and nonrecurring fair value measurements. These additional disclosures include amounts and reasons for significant transfers between Level 1 and Level 2 of the fair value hierarchy; significant transfers in and out of Level 3 of the fair value hierarchy; and information about purchases, sales, issuances and settlements on a gross basis in the reconciliation of recurring Level 3 measurements. The requirements of ASU 2010-6 are effective for periods beginning after December 15, 2009, with the exception of the requirement of information about purchases, sales, issuances and settlements of Level 3 measurements, which becomes effective for periods ending after December 15, 2010. The Company adopted the requirements, with the exception of the requirement for information about purchases, sales, issuances and settlements of Level 3 measurements, during the first quarter of 2010 and the adoption did not have a material impact on our financial position, results of operations or cash flows.

NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

Long-term debt consisted of the following:

We have a five-year, $225.0 million senior unsecured revolving credit facility pursuant to the terms of an amended and restated credit agreement dated August 10, 2006 (the “Credit Agreement”), with Wells Fargo Bank, National Association as successor by merger to Wachovia Bank, National Association (“Wells Fargo”) serving as administrative agent for the lenders. Of the $225.0 million line of credit commitments, $150.0 million may be used for letters of credit and $15.0 million may be used for borrowings under Wells Fargo’s sweep program. The sweep program is a daily cash management tool that automatically initiates borrowings to cover overnight cash requirements up to an aggregate of $15.0 million or initiates overnight investments for excess cash balances. In addition, we have the right to request an increase in the line of credit commitments up to a total of $300.0 million in minimum increments of $25.0 million. At our option, revolving loans under the facility bear interest at either: (a) the higher of Wells Fargo’s prime rate or the federal funds rate plus 0.5% per annum; (b) LIBOR (one, two, three or six months) plus an applicable margin; or (c) one-month LIBOR plus an applicable margin (“LIBOR Index Rate”). The applicable margin is determined by a pricing grid in the Credit Agreement and ranges from 0.5% to 1.125%. The applicable margin for the Credit Agreement during the three months ended March 31, 2010, was 0.625%. Revolving loans under the sweep program bear interest at the LIBOR Index Rate.

The outstanding balance of borrowings on the line of credit facility was $80.0 million and $65.0 million at March 31, 2010 and December 31, 2009, respectively. There were $50.3 million of outstanding letters of credit at March 31, 2010 and December 31, 2009.

We are involved in various legal proceedings and claims that have arisen in the ordinary course of our business that have not been fully adjudicated. Many of these are covered in whole or in part by insurance. Our management does not believe that these actions, when finally concluded and determined, will have a material adverse effect upon our financial position or results of operations.

Management evaluated all subsequent events and transactions through the issuance date of these financial statements, and concluded that no subsequent events or transactions have occurred that require recognition or disclosure in our financial statements.

Overview

We are a leading less-than-truckload (“LTL”), non-union motor carrier providing regional, interregional and national LTL service and value-added logistics services from a single integrated organization. We operate as one business segment and offer our products and services through our four branded product groups: OD-Domestic, OD-Expedited, OD-Global and OD-Technology. In addition to our LTL services, we offer our customers a broad range of logistics services including ground and air expedited transportation, supply chain consulting, transportation management, truckload brokerage, container delivery and warehousing services. Through marketing and carrier relationships, we also offer door-to-door international freight services to and from all of North America, Central America, South America and the Far East. More than 90% of our revenue has historically been derived from transporting LTL shipments for our customers, whose demand for our services is generally tied to industrial production and the overall health of the U.S. domestic economy.

In analyzing the components of our revenue, we monitor changes and trends in the following key metrics:

Our primary revenue focus is to increase shipment and tonnage growth within our existing infrastructure, generally referred to as increasing density, thereby maximizing asset utilization and labor productivity. We measure density over many different functional areas of our operations including revenue per service center, linehaul load factor, pickup and delivery (“P&D”) stops per hour, P&D shipments per hour, platform pounds handled per hour and platform shipments per hour. In addition to our focus on density, it is critical for us to obtain an appropriate revenue yield on the shipments we handle. We manage our yields by focusing on individual account profitability. We believe yield management and improvements in density are key components in our ability to produce profitable growth.

Table of Contents

Our primary cost elements are direct wages and benefits associated with the movement of freight; operating supplies and expenses; and depreciation of our equipment fleet and service center facilities. We gauge our overall success in managing these costs by monitoring our operating ratio, a measure of profitability calculated by dividing total operating expenses by revenue, which also allows industry-wide comparisons with our competition.

We continually upgrade our technological capabilities to improve our customer service and lower our operating costs. Our technology provides customers with visibility of their shipments throughout our network, increases the productivity of our workforce and provides key metrics from which we can monitor our processes.

The following table sets forth, for the periods indicated, expenses and other items as a percentage of revenue from operations:

Table of Contents

Results of Operations

Key financial and operating metrics for the three-month periods ended March 31, 2010 and 2009 are presented below:

During the first quarter of 2010 we experienced year-over-year improvement in business levels and the operating environment, as compared to the unprecedented set of operating challenges we faced in 2009. We remained focused on providing best-in-class service during the first quarter of 2010, which was evidenced by our on-time service performance of approximately 99% and a historically low cargo claims ratio. The combination of our service performance and the improving operating environment led to a 5.8% increase in our tonnage as compared to the first quarter of 2009. This improvement in tonnage and an increase in fuel surcharge revenue resulted in the overall 7.7% increase in our revenue from the prior-year quarter.

We achieved the increases in tonnage and revenue in the first quarter of 2010 without changing our pricing philosophy. In addition, we improved the productivity of our operations and aggressively managed our variable costs. Our linehaul laden load average, P&D stops per hour and platform pounds per hour improved by 0.9%, 1.3% and 3.2%, respectively. Our first quarter of 2010 results also reflect a $2.1 million reduction in our depreciation and amortization expenses due to changes in the estimated useful lives and salvage values of certain equipment. As a result of all of these factors, our operating ratio decreased to 94.8% from 96.6% for the prior-year quarter and net income increased 93.8% to $7.7 million for the first quarter of 2010.

Revenue

Our revenue increased 7.7% to $317.8 million from $295.1 million in the first quarter of 2009. The improvement in first quarter revenue was primarily due to increases in both tonnage shipped and revenue per hundredweight. The increase in tonnage during the first quarter of 2010 resulted from a 5.7% increase in weight per shipment and 0.1% increase in shipments between the comparable quarters. The increase in weight per shipment was primarily due to changes in the overall mix of our freight, as our higher volume shipments made up a larger percentage of our total shipments. The increase in weight per shipment was primarily due to changes in the overall mix of our freight, as our higher volume shipments made up a larger percentage of our total, as well as a general increase in the weight for most of our shipments.

Revenue per hundredweight increased 2.1% to $12.84 in the first quarter of 2010 from $12.57 in the same period of 2009. The increase in our revenue per hundredweight for the first quarter of 2010 reflects an increase in fuel surcharge revenue partially offset by the overall unfavorable impact on this metric caused by changes in the weight, length of haul and other characteristics of our freight. Fuel surcharge revenue increased to 11.6% of revenue from 8.3% in the first quarter of 2009 as a result of an increase in the average price of diesel fuel. Revenue per hundredweight, excluding fuel surcharges, decreased 1.5% from the first quarter of 2009 primarily due to changes in the characteristics of our freight. In contrast, our revenue per shipment, excluding fuel surcharges, increased 4.1% from the comparable period.

Table of Contents

We believe our commitment to providing a superior level of customer service has differentiated us in the marketplace and allowed us to maintain relative stability with our pricing throughout the recent recession. Our on-time and claims-free service performance has been critical in providing us the ability to charge a fair and reasonable price for our services, despite the pricing pressures we have faced in the marketplace. We intend to maintain our pricing philosophy of continuously monitoring the components of our pricing, including base freight rates and fuel surcharges, and address individual account profitability with our customers, when necessary. Price increases have been difficult to obtain throughout the recession, however, due to the competitive pricing environment that resulted from reduced freight demand and overcapacity in the industry. Although the pricing environment remains competitive, we have observed recent trends that we believe may result in an improvement to the pricing environment in 2010. However, any further decreases in the demand for freight or increased price competition within the industry could impact our ability to maintain or increase our pricing in future periods, which could have a material adverse impact on our revenue and net income.

Operating Costs and Other Expenses

Salaries, wages and benefits decreased to 56.9% of revenue for the first quarter of 2010 from 59.9% for the first quarter of 2009. The decrease, as a percent of revenue, primarily resulted from our salaries, wages and benefits increasing $4.1 million, or 2.3%, as compared to the prior-year quarter despite the 7.7% increase in revenue. Although tonnage increased 5.8%, our shipment count remained relatively consistent allowing us to efficiently handle the increased volume. We achieved this primarily through the increased productivity of our employees, as there was a 4.6% reduction in the total number of full-time employees from March 31, 2009 to March 31, 2010. Despite the reduction in the number of full-time employees, the $4.1 million increase in salaries, wages and benefits from the comparable quarter was due to an increase in performance-based pay associated with the increase in income before taxes, an increase in hours worked and scheduled wage increases provided to our driver and platform workers hired within the past three years as they gained experience. In addition, there was an increase in employee benefit costs to 35.1% of salaries and wages from 34.7% in the first quarter of 2009.

Operating supplies and expenses increased to 16.5% of revenue for the first quarter of 2010 from 13.8% for the first quarter of 2009. The increase is primarily due to an $11.2 million increase in our diesel fuel costs, excluding fuel taxes, which is the largest component of operating supplies and expenses. The increase in our diesel fuel costs is primarily the result of a 34.8% increase in our average price per gallon as compared to the first quarter of 2009. In addition, there was a 2.3% increase in gallons consumed as compared to the prior-year quarter. We do not use diesel fuel hedging instruments and are therefore subject to market price fluctuations.

The decrease in insurance and claims expense to 1.7% of revenue from 2.3% of revenue in the first quarter of 2009 is primarily attributable to the 52.9% decrease in cargo claims expense. In the first quarter of 2010, our cargo claims ratio continued to improve from the historically low levels we experienced in 2009 and total claims paid were approximately $1.4 million, or 44.4% less than the same period of 2009. We believe this improvement was the result of our continued focus on claims prevention through our ongoing investment in certain equipment and materials that help minimize claims, the continued training of our employees and the success of our safety program in reducing our accident frequency ratio.

Depreciation and amortization expense decreased to 6.8% of revenue for the first quarter of 2010 from 7.8% of revenue for the same period of 2009. Approximately 70 basis points of the improvement as a percent of revenue is attributable to the net effect on depreciation from changes in the estimated useful lives and salvage values of certain equipment, effective January 1, 2010. The changes we made are described in more detail under “Critical Accounting Policies” below. The impact of these changes resulted in a $2.1 million decrease in depreciation expense during the first quarter of 2010.

We purchase transportation services from other motor carriers and railroads for linehaul and P&D services. We also contract with lease operators for our container operations. We utilize these services when it is economically beneficial or when there are imbalances of freight flow within our service center network. Purchased transportation increased to 2.9% of revenue for the first quarter of 2010 from 2.7% for the prior-year period. These costs increased primarily due to certain imbalances of freight flow within

our network associated with the increase in our tonnage. If we continue to experience tonnage growth in 2010, we plan to employ more drivers and reduce our use of these services as it is more efficient to utilize our own personnel and equipment.

Our effective tax rate was 40.0% for the first quarter of 2010 as compared to 39.3% for the prior-year quarter, which benefited from the alternative fuel tax credits for the use of propane in our operations that expired on December 31, 2009. The effective tax rate exceeded the federal statutory rate of 35.0% primarily due to the impact of state taxes and, to a lesser extent, certain non-deductible items.

Liquidity and Capital Resources

A summary of our cash flows is presented below:

We have two primary sources of available liquidity to meet our operating, investing and financing needs: cash flows from operations and available borrowings under our senior unsecured revolving credit facility, which is described below. We believe we also have sufficient access to debt and equity markets, which provide an alternative source of liquidity, if needed. To facilitate our access to the equity markets, we have an automatic shelf registration statement on file with the Securities and Exchange Commission (the “SEC”) that provides us with the opportunity to offer and sell shares of common stock on a delayed or continuous basis at indeterminate prices from time to time.

Capital Expenditures

Our capital expenditure requirements are generally based upon expansion in the number and size of service center facilities to support our plan for long-term growth, our planned tractor and trailer replacement cycle and forecasted revenue growth. In order to support these requirements, we purchased property and equipment of $27.5 million during the first quarter of 2010.

The table below sets forth our capital expenditures for property and equipment, including capital assets obtained through acquisition of business assets and capital leases, for the three-month period ended March 31, 2010 and the years ended December 31, 2009, 2008 and 2007:

13

Table of Contents

We currently project capital expenditures, net of anticipated proceeds from dispositions, to be approximately $95.0 million for the year ending December 31, 2010. Of our capital expenditures, approximately $50.0 million is allocated for the purchase of service center facilities, construction of new service center facilities or repairs and expansion of existing service center facilities; approximately $25.0 million is allocated for the purchase of tractors, trailers and other equipment; and approximately $16.0 million is allocated for investments in technology. We plan to fund the remaining balance of projected capital expenditures primarily through cash flows from operations and the use of our senior unsecured revolving credit facility, if necessary.

Financing Agreements

We have a five-year, $225.0 million senior unsecured revolving credit facility, which was established pursuant to the terms of an amended and restated credit agreement dated August 10, 2006 (the “Credit Agreement”), with Wells Fargo Bank, National Association as successor by merger to Wachovia Bank, National Association (“Wells Fargo”) serving as administrative agent for the lenders. Of the $225.0 million line of credit commitments, $150.0 million may be used for letters of credit and $15.0 million may be used for borrowings under Wells Fargo’s sweep program. The sweep program is a daily cash management tool that automatically initiates borrowings to cover overnight cash requirements up to an aggregate of $15.0 million or initiates overnight investments for excess cash balances. The amounts outstanding and remaining borrowing capacity under the Credit Agreement are presented below:

We have two unsecured senior note agreements outstanding totaling $228.6 million and $239.3 million at March 31, 2010 and December 31, 2009, respectively. These notes call for periodic principal payments with maturities in 2015 and 2016. The first principal payment on our 2016 notes of $25.0 million was due in April 2010. We utilized our available borrowing capacity under the Credit Agreement to fund a portion of this principal payment and, as a result, the outstanding balance of our borrowings under the Credit Agreement increased to $100.0 million at April 30, 2010.

With the exception of borrowings pursuant to the Credit Agreement, interest rates are fixed on all of our debt instruments. Therefore, short-term exposure to fluctuations in interest rates is limited to our line of credit facility. We do not currently use interest rate derivative instruments to manage exposure to interest rate changes.

Our Credit Agreement limits the amount of dividends that may be paid to shareholders pursuant to the greater of (i) $10.0 million; (ii) the amount of dividends paid in the immediately preceding fiscal year; or (iii) an amount equal to 25% of net income from the immediately preceding fiscal year. We did not declare or pay a dividend on our common stock in first three months of 2010, and we have no plans to declare or pay a dividend during the remainder of 2010.

A significant decrease in demand for our services could limit our ability to generate cash flow and affect profitability. Our Credit Agreement and two unsecured senior note agreements have covenants that require stated levels of financial performance, which if not achieved could cause acceleration of the payment schedules. As of March 31, 2010, we were in compliance with these covenants. We do not anticipate a decline in business levels or financial performance in 2010 that would cause us to violate our financial covenants, and we believe the combination of our existing Credit Agreement along with our additional borrowing capacity will be sufficient to meet our foreseeable seasonal and long-term capital needs.

Critical Accounting Policies

In preparing our condensed financial statements, we applied the same critical accounting policies as described in our Annual Report on Form 10-K for the year ended December 31, 2009 that affect judgments and estimates of amounts recorded for certain assets, liabilities, revenue and expenses, except for the changes made to estimates within our property and equipment policy, as described below.

Property and Equipment

Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated economic lives. Management uses historical experience, certain assumptions and estimates in determining the economic life of each asset. Periodically, we review property and equipment for impairment due to changes in operational and market conditions, and we adjust the carrying value and economic life of any impaired asset as appropriate.

During the first quarter of 2010, we completed an evaluation of the estimated useful lives and salvage values for our equipment and determined that the actual period of service of certain revenue equipment and other equipment exceeded that of our previously estimated useful lives. As a result, we extended the estimated useful lives of most of our tractors to 9 years from 7 years and extended the estimated useful lives of our trailers to 15 years from 12 years. In addition, we reduced the estimated salvage values associated with this equipment to more accurately reflect the value we believe such equipment will have at the end of its respective useful life. We made similar changes to the estimated useful lives and salvage values for certain of our other equipment, but the results of these changes have less of an impact on our future depreciation expense. As a result of the impact on depreciation from these changes that were effective January 1, 2010, income from continuing operations increased by approximately $2.1 million and net income increased by approximately $1.3 million, or $0.03 per diluted share for the first quarter of 2010. We expect the results of these changes to increase income from continuing operations and net income in 2010 by approximately $12.7 million and $7.6 million, or $0.20 per diluted share, respectively.

Effective January 1, 2010, estimated economic lives for structures are 7 to 30 years; revenue equipment is 4 to 15 years; other equipment is 2 to 20 years; and leasehold improvements are the lesser of the economic life of the leasehold improvement or the remaining life of the lease. The use of different assumptions, estimates or significant changes in the resale market for our equipment could result in material changes in the carrying value and related depreciation of our assets.

Seasonality

Our tonnage levels and revenue mix are subject to seasonal trends common in the motor carrier industry, although other factors, such as the economy, could cause variation in these trends. Operating margins in the first quarter are normally lower due to reduced shipments during the winter months. Harsh winter weather can also adversely impact our performance by reducing demand and increasing operating expenses. Freight volumes typically build to a peak in the third or early fourth quarter, which generally results in improved operating margins for those periods. We believe seasonal trends will continue to impact our business; however, our tonnage trends could continue to be inconsistent with historical trends until there is a sustained improvement in the domestic economy.

Environmental Regulation

We are subject to various federal, state and local environmental laws and regulations that focus on, among other things: the emission and discharge of hazardous materials into the environment or their presence on or in our properties and vehicles; fuel storage tanks; transportation of certain materials; and the discharge or retention of storm water. Under specific environmental laws, we could also be held responsible for any costs relating to contamination at our past or present facilities and at third-party waste disposal sites. We do not believe that the cost of compliance with environmental laws or regulations will have a material adverse effect on our operations, financial condition, competitive position or capital expenditures for the remainder of fiscal year 2010 or fiscal year 2011.

We are exposed to interest rate risk directly related to loans under our Credit Agreement, which have variable interest rates. The average principal balance and the effective annual interest rate under the revolving credit agreement for the three-month period ended March 31, 2010 were $76.7 million and 1.6%, respectively. A 100 basis point increase in the average interest rate on this agreement would have a $0.8 million impact on our annual operating income. We have established policies and procedures to manage our exposure to market risk and use major institutions that we believe are creditworthy to minimize credit risk.

We are exposed to market risk for equity investments relating to Company-owned life insurance contracts on certain employees. Variable life insurance contracts expose the Company to fluctuations in equity markets; however, we utilize a third-party to manage these assets and minimize that exposure.

We are also exposed to commodity price risk related to diesel fuel prices and manage our exposure to this risk primarily through the application of fuel surcharges.

For further discussion related to these risks, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Item 2 of this report.

As of the end of the period covered by this quarterly report, our management, with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), conducted an evaluation of the effectiveness of our disclosure controls and procedures in accordance with Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on the evaluation of our disclosure controls and procedures as of the end of the period covered by this quarterly report, our CEO and CFO concluded that, as of such date, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is (a) accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure, and (b) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

There were no changes in our internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We are involved in various legal proceedings and claims that have arisen in the ordinary course of our business that have not been fully adjudicated. Many of these are covered in whole or in part by insurance. Our management does not believe that these actions, when finally concluded and determined, will have a material adverse effect upon our financial position or results of operations.

In addition to the other information set forth in this report and in our other reports and statements that we file with the SEC, including our quarterly reports on Form 10-Q, careful consideration should be given to the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2009, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K are not the only risks facing our
