NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Basis of Presentation

The accompanying unaudited consolidated interim financial statements reflect, in the opinion of management, 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. The preparation of financial statements in accordance with accounting principles generally accepted in the United States 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 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 periods are not necessarily indicative of the results for the entire year.

There have been no significant changes in the accounting policies of Old Dominion Freight Line, Inc. or significant changes in our commitments and contingencies as previously described in the 2003 Annual Report to Shareholders and related annual report to the Securities and Exchange Commission on Form 10-K.

Common Stock Split

On April 22, 2004, Old Dominion announced a three-for-two stock split in the form of a 50% stock dividend for shareholders of record at the close of business on May 6, 2004. The distribution of those shares was effective May 20, 2004, and all references in this report to shares outstanding, weighted average shares outstanding and earnings per share have been restated retroactively for this stock split.

Revolving Credit Agreement

We entered into an unsecured revolving credit agreement dated June 30, 2003 with lenders consisting of Wachovia Bank, N.A.; Bank of America, N.A.; and Branch Banking and Trust Company, with Wachovia as agent for the lenders. This three-year facility, as amended, consists of $80,000,000 in line of credit commitments from the lenders, all of which are available for revolving loans. In addition, of that $80,000,000 line of credit, $40,000,000 may be used for letters of credit and $10,000,000 may be used for borrowings under Wachovia’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 $10,000,000 or initiates overnight investments for excess cash balances. Revolving loans under the facility bear interest at either: (a) an applicable margin plus the higher of Wachovia’s prime rate or one-half of one percentage point over the federal funds rate (the “Adjusted Base Rate”); or (b) LIBOR plus an applicable margin (the “Adjusted LIBOR Rate”). The applicable margin varies depending upon our ratio of adjusted debt to capital. In the case of the Adjusted Base Rate, the applicable margin ranges from 0% to .25%. In the case of the Adjusted LIBOR Rate, the applicable margin ranges from .75% to 1.25%. The applicable margin under this agreement for the second quarter of 2004 for the Adjusted Base Rate and the Adjusted LIBOR Rate was 0% and 1.0%, respectively. Revolving loans under the sweep program bear interest at the aggregate rate applicable under the sweep program plus the Adjusted LIBOR Rate.

Quarterly fees ranging from .20% to .30% are charged on the aggregate unused portion of the facility determined by our ratio of adjusted debt to capital. The applicable rate for the second quarter of 2004 was .25%. Quarterly fees are charged on the aggregate undrawn portion of outstanding letters of credit at a rate ranging from .75% to 1.25%, which was 1.0% for the second quarter of 2004 as determined by our ratio of adjusted debt to capital. In addition, a quarterly facing fee at an annual rate of .125% was charged on the aggregate undrawn portion of outstanding letters of credit.

The June 2003 credit facility contains customary covenants, including financial covenants that require us to observe a maximum ratio of adjusted debt to capital, to maintain a minimum fixed charge coverage ratio and to maintain a minimum consolidated tangible net worth. Our wholly owned subsidiary guaranteed payment of all of our obligations under the facility. Future wholly owned subsidiaries would be required to guarantee payment of all of our obligations under the facility. At June 30, 2004, there was $37,500,000 outstanding on the line of credit facility and there was $31,047,000 outstanding on the standby letter of credit facility.

Stock Based Compensation

Stock based compensation expense for our employee stock option plan is recognized under the provisions of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (“APB 25”), and related interpretations. Consistent with APB 25, the exercise price of our employee stock options equals the market price of the underlying stock on the date of grant; therefore, no compensation expense is recognized. Pro forma information regarding net income and earnings per share required by SFAS No. 123, Accounting for Stock-Based Compensation, is not significant.

Recent Accounting Pronouncements

In January 2003, the FASB issued SFAS Interpretation No. 46 (“FIN 46”), Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51, which addresses consolidation by business enterprises of variable interest entities (“VIEs”) either: (1) that do not have sufficient equity investment at risk to permit the entity to finance its activities without additional subordinated financial support, or (2) in which the equity investors lack an essential characteristic of a controlling financial interest. In December 2003, the FASB issued modifications to FIN 46 (“Revised Interpretations”) resulting in multiple effective dates based on the nature as well as the creation date of the VIE. VIEs created after January 31, 2003, but prior to January 1, 2004, may be accounted for either based on the original interpretation or the Revised Interpretations. However, the Revised Interpretations were required to be applied no later than the first quarter 2004. VIEs created after January 1, 2004 must be accounted for under the Revised Interpretations. Non-Special Purpose Entities created prior to February 1, 2003, should be accounted for under the Revised Interpretations’ provisions no later than the first quarter of fiscal 2004. We have adopted FIN 46, which did not have a material impact on our consolidated financial statements.

Related Party Transactions

Transactions with Old Dominion Truck Leasing, Inc.

Old Dominion Truck Leasing, Inc. (“Leasing”), a North Carolina corporation whose voting stock is owned by the Earl E. Congdon Intangibles Trust, David S. Congdon, Trustee, the John R. Congdon Revocable Trust and members of Earl E. Congdon’s and John R. Congdon’s families, is engaged in the business of purchasing and leasing tractors, trailers and other vehicles. John R. Congdon is Chairman of the Board of Leasing, and Earl E. Congdon is Vice Chairman of the Board of Leasing. Since 1986, we have combined our requirements with Leasing for the purchase of tractors, trailers, equipment, parts, tires and fuel. We believe that, by combining our requirements, we are often able to obtain pricing discounts because of the increased level of purchasing. While this is beneficial to us, our management believes that the termination of this relationship would not have a material adverse impact on our financial results.

We provide vehicle repair, maintenance and other services to Leasing at cost plus a negotiated markup, and we rent vehicle repair facilities to Leasing at two of our service center locations for fair market value. For these services and use of these facilities, we charged Leasing $16,000 and $15,000 for the first six months of 2004 and 2003, respectively.

We purchased $185,000 and $133,000 of maintenance and other services from Leasing in the first six months of 2004 and 2003, respectively. We did not lease any equipment from Leasing in the first six months of 2004 or for the entire year 2003. One trailer was purchased from Leasing on May 1, 2003 for a purchase price of $8,000.

Transactions with E & J Enterprises

On July 29, 2002, our Board of Directors approved the purchase of 163 trailers for $1,200 each, or a total of $195,600, from E & J Enterprises, a Virginia general partnership of which Earl E. Congdon, our Chief Executive Officer and Chairman of our Board of Directors, and John R. Congdon, Vice Chairman of our Board of Directors, are each 50% owners. These trailers had been leased to us by E & J Enterprises

8

since 1988 pursuant to a term lease, which converted to a month-to-month lease in 1999. At year-end 2002, we had completed the purchase of 50 of these trailers for a purchase price of $60,000. During the first quarter 2003, we continued to lease the remaining 113 trailers on a month-to-month basis until we completed the purchase of those trailers in March 2003 for a purchase price of $135,600. Also in March 2003, we purchased 10 additional trailers from E & J Enterprises for $5,000 each for a total purchase price of $50,000.

On July 29, 2002, our Board of Directors also approved the leasing from E & J Enterprises of 150 pickup and delivery trailers on a month-to-month basis for $204 per month for each trailer. On December 1, 2003, we purchased these 150 trailers for an aggregate purchase price of $907,000. The total amount paid for all trailers under lease was $0 and $204,000 for the first six months of 2004 and 2003, respectively.

Earnings Per Share

Net income per share of common stock is based on the weighted average number of shares outstanding during each period after giving retroactive effect for the three-for-two stock split that was effective on May 20, 2004.

Subsequent Events

On July 26, 2004, we issued and sold in an underwritten public offering, 370,000 shares of common stock in exchange for proceeds of $10,097,300, after deducting underwriting discounts and commissions. In addition to the shares sold by the Company in this public offering, Earl E. Congdon, our Chairman of the Board of Directors, and John R. Congdon, our Vice Chairman of the Board of Directors, and members of their respective families, sold an additional 2,070,000 shares of common stock.

On August 4, 2004, the underwriters for this public offering exercised their option to purchase from us an additional 366,000 shares of common stock to cover over-allotments. In exchange for these shares, we received proceeds of $9,988,140, after deducting all underwriting discounts and commissions.

Expenses associated with this offering will reduce the aggregate proceeds received by the Company by approximately $250,000.

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

Overview

We are a leading less-than-truckload multi-regional motor carrier providing timely one to five day service among five regions in the United States and next-day and second-day service within these regions. Through our four branded product groups, OD-Domestic, OD-Expedited, OD-Global and OD-Technology, we offer an expanding array of innovative products and services. At June 30, 2004, we provided full-state coverage to 28 of the 40 states that we serve directly within the Southeast, South Central, Northeast, Midwest and West regions of the country. Through marketing and carrier relationships, we also provide service to and from the remaining 10 states as well as international services around the globe.

We combine the rapid transit times of a regional carrier with the geographic coverage of an inter-regional carrier. We believe our transit times are generally faster than those of our principal national competitors and we are highly competitive with our principal regional competition. Historically, over 90% of our revenue is derived from transporting LTL shipments.

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 and platform pounds per hour. We believe density is a key component in our ability to sustain or increase profitable growth.

The majority of direct costs associated with our business are driver and service center wages and benefits, 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. This technology provides our customers with visibility of their shipments throughout our systems, while providing key metrics from which we can monitor our processes.

10

We believe our non-union workforce gives us a significant advantage over our unionized LTL competition. Advantages of our workforce include flexible hours and the ability of our employees to perform multiple tasks, which we believe result in greater productivity, customer service, efficiency and cost savings. We focus on communication and the continued education, development and motivation of our employees to promote our relationships with our employees.

Market fluctuations in the cost of key components of our cost structure, such as diesel fuel, affect our profitability. Our tariffs and contracts generally provide for a fuel surcharge as diesel fuel prices increase above stated levels. We are also subject to market changes in insurance rates, and we continue to evaluate our balance of excess insurance coverage and self-insurance to minimize that cost.

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

Results of Operations

For the second quarter and the first six months of 2004, we continued to produce double-digit growth in revenue, profitability and earnings per share. Second quarter revenue grew 23.4% to $202,129,000 from $163,817,000 for the prior-year comparable quarter. When combined with the 19.6% increase in revenue we recorded in the first quarter, our revenue grew to $384,898,000 for the first six months of 2004, an increase of 21.5% over the same period in 2003.

11

The additional revenue we produced in 2004 reflects an increase in our operational density and resulted in certain operating efficiencies that decreased our operating ratio. For the second quarter 2004 our operating ratio was 90.6% compared to 92.6% for the prior-year period. For the first six months of 2004 our operating ratio was 92.3% compared to 93.4% for the first six months of 2003. As a result, net income for the second quarter increased 60.7% to $10,461,000 and net income for the first six months of 2004 increased 50.4% to $16,173,000.

Basic and diluted earnings per share for the second quarter increased 59.3% to $.43, compared to $.27 for the second quarter of 2003. For the first six months of 2004, diluted earnings per share increased 48.9% to $.67 from $.45 for the same period in 2003.

Revenue

Revenue increases in the second quarter and the first half of 2004 were primarily a result of volume increases in LTL tonnage and LTL shipments. LTL tonnage grew 18.0% in the second quarter and 17.9% for the first half of the year compared to the same periods in 2003. LTL shipments grew 12.9% for the current quarter and 14.3% for the first six months of the year. Because LTL tonnage grew at a faster rate than LTL shipments, our weight per LTL shipment increased 4.4% to 1,062 pounds for the quarter and increased 3.1% to 1,052 for the first half of 2004.

We attribute the increase in LTL weight per LTL shipment to an improving economic environment and to a slight shift in our customer base. Since February 2004, we have experienced a trend of monthly increases in LTL weight per LTL shipment, which we believe indicates greater demand for our customers’ products and a resulting increase in shipment size and weight. In addition, we have seen higher year-over-year growth rates in our customer base that is priced through individual contracts. Our contract business increased approximately 33% over the second quarter 2003 and approximately 34% over the first six months of 2003. We believe the expansion of our service center network and full-state coverage in 28 of those states has positioned us to be attractive to larger customers that ship to and from many regions in the country and seek to reduce their number of core carriers. Our contract customers generally offer larger shipments, which increases our average LTL weight per LTL shipment.

Typically, our revenue per hundredweight on contract business is priced lower than non-contract business, due to allowances for operating efficiencies gained from the increased number, size and consistency of the shipments, as well as the long-term potential benefit of these contractual relationships. Despite this impact, our LTL revenue per LTL hundredweight increased 2.4% for the comparative quarters and 1.3% for the comparative six-month periods. This increase was partially due to increases in our average length of haul to 937 miles for the second quarter, an increase of .8% over the comparable quarter in 2003, and to 945 miles for the first half of 2004, an increase of 2.2% over the same period in 2003. In addition, we implemented a general price increase on our public tariff base rates on June 1, 2004, which impacted approximately 40% of our revenue base.

The combination of increases in LTL weight per LTL shipment and LTL revenue per LTL hundredweight produced improvements in LTL revenue per LTL shipment. LTL revenue per LTL shipment was $155.68 for the second quarter of 2004 and $153.07 for the first half of the year, an improvement over the prior-year period of 7.0% and 4.5%, respectively.

During the first half of 2004, we opened service centers in Bakersfield, California; Sarasota, Florida; Dayton and Youngstown, Ohio; Portland, Oregon; Seattle, Washington; and La Crosse and Wausau, Wisconsin. In addition to these openings, we improved our direct service capabilities in Canada and initiated sales operations in Toronto and Montreal. In the second quarter of 2004, we began providing full-state coverage in Wisconsin and on August 2, 2004, we also began to provide full-state coverage in Michigan, increasing our full-state coverage to 29 states. While the expansion of our service center network and improvement in our service capabilities should provide a platform for future growth, these events did not have a significant impact on our second quarter and six-month results.

Our tariffs and contracts generally provide for a fuel surcharge as diesel fuel prices increase above stated levels. This surcharge is recorded as additional revenue and is intended to offset significant fluctuations in the price of diesel fuel, which is one of the larger components of our operating expenses.

12

Due to increases in diesel fuel prices in 2004, our fuel surcharge per gallon of fuel consumed increased 39.6% over the second quarter of 2003 and 13.7% over the comparable six-month periods.

In the first six months of 2004, we exceeded our targeted revenue growth projections of between 10% and 15% that was established as our goal for 2004. Based upon these results and our current projections, we are confident of achieving this goal for the entire year of 2004.

Operating Costs and Other Expenses

During the second quarter and first half of 2004, increases in tonnage and concentrations of shipments moving through our route structure and service center network generated operating efficiencies that resulted in increased profitability. The benefits of this improved density, measured over many functions of our operations, were instrumental in the reduction of our operating ratio to 90.6% for the second quarter and 92.3% for the first half of the year compared to prior-year periods of 92.6% and 93.4%, respectively. Much of that improvement was achieved through reductions as a percentage of revenue in salaries, wages and benefits, the largest component of our cost structure, which decreased to 57.0% of revenue for the second quarter from 59.3% for the second quarter of 2003, and decreased to 58.1% of revenue for the first half of 2004 from 59.7% for the first half of 2003.

The additional freight volumes enabled us to leverage the costs of our salaried and clerical workforce. In the comparative second quarters, salary and clerical wages decreased to 12.9% of revenue from 13.3% and decreased to 12.8% of revenue from 13.6% for the comparable six-month periods.

We continued to reduce our P&D driver labor as a percent of revenue, which decreased to 11.1% for the second quarter from 11.9% for the same quarter of 2003. For the first six months of 2004, P&D driver labor decreased to 11.4% of revenue from 11.9% for the comparable period in 2003. A portion of these savings resulted from the rollout of our driver hand-held computers, which was completed by year-end 2003. These handheld computers provide direct communication between our drivers, service center personnel and other Old Dominion systems, which results in more efficient routing of our P&D fleet and increased productivity. In addition, these devices allow our drivers to capture real-time information during pickups and deliveries, including the number and weight of shipments as well as other vital shipping information that allows for increased efficiency in our dock and linehaul operations. For the six-month comparable periods, we achieved a 2.3% increase in P&D shipments per hour and a .6% improvement in P&D stops per hour.

Linehaul driver wages decreased to 11.8% from 12.1% for the comparative second quarters and decreased to 11.9% from 12.1% for the comparative six-month periods. Our linehaul laden load average, a measurement of linehaul trailer utilization, increased 4.2% for the second quarter of 2004 and 3.9% for the first half of 2004 over the comparable year periods. In addition, revenue per linehaul mile increased to $3.74 for the second quarter and to $3.70 for the first half of 2004, reflecting increases over the prior-year periods of 7.5% and 5.7%, respectively.

We purchase transportation services for our linehaul and local pickup and delivery operations from other motor carriers and rail providers when there are capacity restraints or imbalances of freight flow within our service center network or when it is economically beneficial. Purchased transportation increased to 3.4% of revenue from 3.0% for the comparative quarters and increased to 3.4% of revenue from 3.1% for the six-month periods, primarily due to increases in purchased motor and rail linehaul services. During the first half of 2004, these services were utilized to offset freight imbalances so that we could more efficiently utilize our drivers and equipment fleet.

Operating supplies and expenses increased to 11.4% of revenue for the second quarter of 2004 from 10.6% and increased to 11.4% of revenue for the first six months of 2004 from 11.2%, primarily due to diesel fuel price fluctuations. Diesel fuel costs, excluding fuel taxes, increased to 6.2% of revenue for the second quarter compared to 5.2% for the same period in 2003. For the comparable six-month periods, diesel fuel increased to 6.2% of revenue from 5.7%. We currently do not use diesel fuel hedging instruments; therefore, we are subject to price fluctuations and our ability to apply fuel surcharges. We believe that our fuel surcharges, which decrease or are eliminated as fuel prices approach base levels, have effectively offset price fluctuations in diesel fuel in 2004.

13

The 23.4% revenue growth in the second quarter 2004 enabled us to leverage our investments in property and equipment, thereby reducing our depreciation expense to 5.4% compared to 5.8% in the second quarter of 2003. For the comparable six months, depreciation expense decreased slightly to 5.6% from 5.7%. Approximately 81% of our 2004 planned net capital expenditures, or $68,536,000, was completed in the first half of the year for planned asset replacements and in order to increase our fleet and service center capacity to accommodate our growth. In addition, the investments in service centers coupled with a 9.4% increase in revenue per service center for the first half of 2004 resulted in a decrease in net service center lease costs of .1% of revenue for both the second quarter and first six months of 2004 versus the respective prior-year periods.

Insurance expenses, primarily for bodily injury, property damage and cargo claims, increased to 3.4% of revenue for the second quarter and 3.3% for the first half of 2004 compared to 3.0% and 2.8% for the respective periods in 2003. We choose to self-insure a portion of our bodily injury, property damage and cargo claims liabilities and obtain excess insurance coverage for claims above our retention levels. In the second quarter of 2004, self-insured bodily injury and property damage expenses, resulting from claims under insured retention levels, increased to 1.5% of revenue from 1.0% and increased to 1.3% for the first six months of 2004 from .8% for the same period in 2003.

During the second quarter and the first half of 2004, we successfully leveraged other costs, including operating taxes and licenses, communications and utilities, and miscellaneous expenses, which as a group decreased to 5.6% of revenue for the second quarter and 6.0% for the first half of 2004 compared to 6.3% of revenue for both comparable periods in 2003.

Long-term debt including current maturities was $107,310,000 at June 30, 2004 compared to $100,336,000 at June 30, 2003, an increase of 7.0%. Because our credit facility carries a lower interest rate than our senior notes, and due to a shift of average outstanding debt from senior notes to the credit facility, our interest expense for the second quarter and first half of 2004 decreased from the previous year comparable periods. Interest expense, net of interest income, decreased $171,000 for the comparative second quarters and $234,000 for the comparative six-month periods. We also capitalized $66,000 more interest in the second quarter and first six months of 2004 than the previous year periods, which also contributed to the decrease in net interest expense.

The effective tax rates for the second quarter and first half of 2004 were 39.5% and 39.3%, respectively, compared to 39.5% for the same periods in 2003.

Liquidity and Capital Resources

Expansion in both the size and number of service center facilities, our planned tractor and trailer replacement cycle and revenue growth have required continued investment in real estate and equipment. In order to support these requirements, we incurred net capital expenditures of $68,536,000 in the first six months of 2004. Cash and cash flows generated internally during the first six months of 2004 funded approximately 86% of these expenditures, the remainder of which were funded through additional borrowings. At June 30, 2004, long-term debt including current maturities increased to $107,310,000 from $97,426,000 at December 31, 2003.

We estimate net capital expenditures to be approximately $80,000,000 to $85,000,000 for the year ending December 31, 2004. Of that, approximately $55,000,000 is allocated for the purchase of tractors and trailers; $17,000,000 is allocated for the purchase of service center facilities, construction of new service center facilities or expansion of existing service center facilities; $8,000,000 is allocated for investments in technology; and the balance is allocated for other assets. We plan to fund these capital expenditures primarily through cash flows from operations supplemented by additional borrowings.

14

The table below sets forth our capital expenditures for the first six months of 2004 and the years ended December 31, 2003, 2002 and 2001, excluding assets acquired as part of business acquisitions:

We entered into an unsecured revolving credit agreement dated June 30, 2003 with lenders consisting of Wachovia Bank, N.A.; Bank of America, N.A.; and Branch Banking and Trust Company, with Wachovia as agent for the lenders. This three-year facility, as amended effective April 14, 2004, consists of $80,000,000 in line of credit commitments from the lenders, all of which are available for revolving loans. In addition, of that $80,000,000 line of credit, $40,000,000 may be used for letters of credit and $10,000,000 may be used for borrowings under Wachovia’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 $10,000,000 or initiates overnight investments for excess cash balances. Revolving loans under the facility bear interest at either: (a) an applicable margin plus the higher of Wachovia’s prime rate or one-half of one percentage point over the federal funds rate (the “Adjusted Base Rate”); or (b) LIBOR plus an applicable margin (the “Adjusted LIBOR Rate”). The applicable margin varies depending upon our ratio of adjusted debt to capital. In the case of the Adjusted Base Rate, the applicable margin ranges from 0% to .25%. In the case of the Adjusted LIBOR Rate, the applicable margin ranges from .75% to 1.25%. The applicable margin under this agreement for the second quarter of 2004 for the Adjusted Base Rate and the Adjusted LIBOR Rate was 0% and 1.0%, respectively. Revolving loans under the sweep program bear interest at the aggregate rate applicable under the sweep program plus the Adjusted LIBOR Rate.

Quarterly fees ranging from .20% to .30% are charged on the aggregate unused portion of the facility determined by our ratio of adjusted debt to capital. The applicable rate for the second quarter of 2004 was .25%. Quarterly fees are charged on the aggregate undrawn portion of outstanding letters of credit at a rate ranging from .75% to 1.25%, which was 1.0% for the second quarter of 2004 as determined by our ratio of adjusted debt to capital. In addition, a quarterly facing fee at an annual rate of .125% was charged on the aggregate undrawn portion of outstanding letters of credit.

The June 2003 credit facility contains customary covenants, including financial covenants that require us to observe a maximum ratio of adjusted debt to capital, to maintain a minimum fixed charge coverage ratio and to maintain a minimum consolidated tangible net worth. Our wholly owned subsidiary guaranteed payment of all of our obligations under the facility. Future wholly owned subsidiaries would be required to guarantee payment of all of our obligations under the facility. At June 30, 2004, there was $37,500,000 outstanding on the line of credit facility and there was $31,047,000 outstanding on the standby letter of credit facility.

We have three senior note agreements outstanding totaling $58,714,000 at June 30, 2004. These notes call for periodic principal payments with maturities ranging from 2005 to 2008, of which $16,607,000 is due in the next twelve months. Interest rates on these notes are fixed and range from 6.35% to 7.59%. Under the provisions of one of these notes, we may issue up to $15,000,000 of additional senior notes. The applicable interest rate and payment schedules for any new notes will be determined and mutually agreed upon at the time of issuance.

We have a term loan with principal outstanding of $8,640,000 as of June 30, 2004, which was used to purchase 300 tractors. The borrowing under the term loan is evidenced by 48-month term notes secured

15

by the purchased equipment pursuant to a security agreement with the lender. The notes call for equal monthly payments of principal and interest and mature in 2006, of which $4,052,000 in principal is due within the next 12 months. The interest rates on the notes are fixed and range from 4.21% to 4.39%. The term loan agreement contains customary affirmative and negative covenants. The term notes originally incorporated by reference the financial covenants from our May 2000 credit facility and were amended to incorporate by reference our financial covenants under our June 2003 facility.

With the exception of the line of credit, interest rates are fixed on all of our debt instruments. Therefore, short-term exposure to fluctuations in interest rates is limited to our credit facility, which had an outstanding balance of $37,500,000 at June 30, 2004. We do not currently use interest rate derivative instruments to manage exposure to interest rate changes. Also, we do not use fuel hedging instruments, as our tariff provisions and contracts generally allow for fuel surcharges to be implemented in the event that fuel prices exceed stipulated levels.

A significant decrease in demand for our services could limit our ability to generate cash flow and affect profitability. Most of our debt agreements have covenants that require stated levels of financial performance, which if not achieved could cause acceleration of the payment schedules. We do not anticipate a significant decline in business levels or financial performance, and we believe the combination of our existing credit facilities along with our additional borrowing capacity will be sufficient to meet seasonal and long-term capital needs.

The following table summarizes our significant contractual obligations and commercial commitments as of June 30, 2004:

Critical Accounting Policies

In preparing our consolidated financial statements, we apply the following critical accounting policies that affect judgments and estimates of amounts recorded in certain assets, liabilities, revenue and expenses:

16

Revenue and Expense Recognition - Operating revenue is recognized on a percentage of completion method based on average transit time. Expenses associated with operating revenue are recognized when incurred.

Allowance for Uncollectible Accounts - We maintain an allowance for uncollectible accounts for estimated losses resulting from the inability of our customers to make required payments. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Claims and Insurance Accruals - Claims and insurance accruals reflect the estimated ultimate total cost of claims, including amounts for claims incurred but not reported, for cargo loss and damage, bodily injury and property damage, workers’ compensation, long-term disability and group health not covered by insurance. These costs are charged to insurance and claims expense except for workers’ compensation, long-term disability and group health, which are charged to employee benefits expense.

We are currently self-insured for bodily injury and property damage claims up to $2,000,000 per occurrence. Cargo loss and damage claims are self-insured up to $100,000. We are self-insured for workers’ compensation in certain states and have first dollar or high deductible plans in the remaining states with self-insured retention levels ranging from $250,000 to $1,000,000. Group health claims are self-insured up to $300,000 per occurrence and long-term disability claims are self-insured to a maximum per individual of $3,000 per month.

Insurers providing excess coverage above retention levels adjust their premiums to cover insured losses and for other market factors. As a result, we periodically evaluate our self-insured retention levels to determine the most cost efficient balance of self-insurance and excess coverage.

In establishing accruals for claims and insurance expenses, we evaluate and monitor each claim individually, and we use factors such as historical experience, known trends and third-party estimates to determine the appropriate reserves for potential liability. We believe the assumptions and methods used to estimate these liabilities are reasonable; however, changes in the severity of previously reported claims, significant changes in the medical costs and legislative changes affecting the administration of our plans could significantly impact the determination of appropriate reserves in future periods.

Goodwill - The excess cost over net assets acquired in connection with acquisitions, or goodwill, is recorded in “Other Assets”. We adopted Statement of Financial Accounting Standard No. 142, Goodwill and Other Intangible Assets (“SFAS 142”) on January 1, 2002 and completed the required analyses of the fair value of our single reporting unit compared to the carrying value as of January 1, 2002, October 1, 2002 and October 1, 2003. Based on those analyses, we concluded that there was no impairment of goodwill on those measurement dates. At June 30, 2004, goodwill totaled $10,648,000. Prior to the adoption of SFAS 142, these intangible assets were amortized using a straight-line method over their estimated useful lives of 3 to 25 years.

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 to include changes in operational and market conditions, and we adjust the carrying value and economic life of any impaired asset as appropriate. Currently, estimated economic lives for structures are 5 to 30 years; revenue equipment is 2 to 12 years; other equipment is 2 to 10 years; and leasehold improvements are the lesser of 10 years or the 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 of our assets.

Inflation

Most of our expenses are affected by inflation, which generally results in increased operating costs. In response to fluctuations in the cost of petroleum products, particularly diesel fuel, we have implemented a fuel surcharge in our tariffs and contractual agreements. The fuel surcharge is designed to offset the cost of fuel above a base price and increases as fuel prices escalate over the base. For the first six months of 2004 and the entire year 2003, the net effect of inflation on our results of operations was minimal.

17

Seasonality

Our tonnage levels and revenue mix are subject to seasonal trends common in the motor carrier industry. Financial results 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. The remaining periods reflect increased demand for our services and generally result in improved operating margins.

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 from our properties and vehicles, fuel storage tanks 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 future compliance with environmental laws or regulations will have a material adverse effect on our operations or financial condition.

Related Party Transactions

Transactions with Old Dominion Truck Leasing, Inc.

Old Dominion Truck Leasing, Inc. (“Leasing”), a North Carolina corporation whose voting stock is owned by the Earl E. Congdon Intangibles Trust, David S. Congdon, Trustee, the John R. Congdon Revocable Trust and members of Earl E. Congdon’s and John R. Congdon’s families, is engaged in the business of purchasing and leasing tractors, trailers and other vehicles. John R. Congdon is Chairman of the Board of Leasing, and Earl E. Congdon is Vice Chairman of the Board of Leasing. Since 1986, we have combined our requirements with Leasing for the purchase of tractors, trailers, equipment, parts, tires and fuel. We believe that, by combining our requirements, we are often able to obtain pricing discounts because of the increased level of purchasing. While this is beneficial to us, our management believes that the termination of this relationship would not have a material adverse impact on our financial results.

We provide vehicle repair, maintenance and other services to Leasing at cost plus a negotiated markup, and we rent vehicle repair facilities to Leasing at two of our service center locations for fair market value. For these services and use of these facilities, we charged Leasing $16,000 and $15,000 for the first six months of 2004 and 2003, respectively.

We purchased $185,000 and $133,000 of maintenance and other services from Leasing in the first six months of 2004 and 2003, respectively. We believe that the prices we pay for such services are lower than would be charged by unaffiliated third parties for the same quality of work, and we intend to continue to purchase maintenance and other services from Leasing, provided that Leasing’s prices continue to be favorable to us. We did not lease any equipment from Leasing in the first six months of 2004 or for the entire year 2003.

We also purchased one trailer from Leasing on May 1, 2003 for a purchase price of $8,000.

Transactions with E & J Enterprises

On July 29, 2002, our Board of Directors approved the purchase of 163 trailers for $1,200 each, or a total of $195,600, from E & J Enterprises, a Virginia general partnership of which Earl E. Congdon, our Chief Executive Officer and Chairman of our Board of Directors, and John R. Congdon, Vice Chairman of our Board of Directors, are each 50% owners. These trailers had been leased to us by E & J Enterprises since 1988 pursuant to a term lease, which converted to a month-to-month lease in 1999. At year-end 2002, we had completed the purchase of 50 of these trailers for a purchase price of $60,000. During the first quarter 2003, we continued to lease the remaining 113 trailers on a month-to-month basis until we

18

completed the purchase of those trailers in March 2003 for a purchase price of $135,600. Also in March 2003, we purchased 10 additional trailers from E & J Enterprises for $5,000 each for a total purchase price of $50,000.

On July 29, 2002, our Board of Directors also approved the leasing from E & J Enterprises of 150 pickup and delivery trailers on a month-to-month basis for $204 per month for each trailer. On December 1, 2003, we purchased these 150 trailers for an aggregate purchase price of $907,000. The total amount paid for all trailers under lease was $0 and $204,000 for the first six months of 2004 and 2003, respectively.
