                  SMITHWAY MOTOR XPRESS CORP. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                  (Dollars in thousands, except per share data)
                                   (Unaudited)

NOTE 1. BASIS OF PRESENTATION

      The condensed consolidated financial statements include the accounts of
      Smithway Motor Xpress Corp., a Nevada holding company, and its four wholly
      owned subsidiaries ("we," "us," or "our"). All significant intercompany
      balances and transactions have been eliminated in consolidation.

      The condensed consolidated financial statements have been prepared,
      without audit, in accordance with U.S. generally accepted accounting
      principles, pursuant to the published rules and regulations of the
      Securities and Exchange Commission. In our opinion, the accompanying
      condensed consolidated financial statements include all adjustments that
      are necessary for a fair presentation of the results for the interim
      periods presented, such adjustments being of a normal recurring nature.
      Certain information and footnote disclosures have been condensed or
      omitted pursuant to such rules and regulations. The December 31, 2005,
      Condensed Consolidated Balance Sheet was derived from our audited balance
      sheet for the year then ended. It is suggested that these condensed
      consolidated financial statements and notes thereto be read in conjunction
      with the consolidated financial statements and notes thereto included in
      our annual report on Form 10-K for the year ended December 31, 2005.
      Results of operations in interim periods are not necessarily indicative of
      results to be expected for a full year.

NOTE 2. NET EARNINGS PER COMMON SHARE

      Basic earnings per share have been computed by dividing net earnings by
      the weighted-average outstanding Class A and Class B common shares during
      each of the quarters. Diluted earnings per share have been calculated by
      also including in the computation the effect of employee stock options,
      nonvested stock, and similar equity instruments granted to employees and
      directors as potential common shares. The dilutive effect of stock options
      excludes 55,000 and 42,000 shares for the three months and six months
      ending on June 30, 2005 and 2006, respectively, as the exercise prices of
      the underlying options were out of the money and the effect was
      anti-dilutive. Stock options outstanding at June 30, 2005 and 2006,
      totaled 236,850 and 203,850, respectively.

NOTE 3. STOCK OPTION PLANS

      We have two active stock-based compensation plans:

            (1) We have reserved 400,000 shares of Class A common stock for
            issuance pursuant to an employee incentive stock plan adopted during
            2001. Any shares subject to awards which expire unexercised or are
            forfeited become available again for issuance under this plan. Under
            this plan, no award of incentive stock options may be made after
            August 6, 2011.

            (2) We have reserved 500,000 shares of Class A common stock for
            issuance pursuant to an omnibus stock plan adopted on May 13, 2005.
            Any shares subject to awards which expire unexercised or are
            forfeited become available again for issuance under this plan. This
            plan expires on May 13, 2015.

      Options granted under these plans vest in installments from 12 to 60
      months after the date of grant. The options are exercisable over a period
      not to exceed ten years from the date of grant. At June 30, 2006, 822,500
      shares were available for granting additional options.

                                        7


      Effective January 1, 2006, we adopted Statement of Financial Accounting
      Standards ("SFAS") No. 123 (revised 2004), "Share-Based Payment" ("No.
      123R"), using a modified version of the prospective transition method.
      Under this transition method, compensation cost is recognized on or after
      the required effective date for the portion of outstanding awards for
      which the requisite service has not yet been rendered, based on the
      grant-date fair value of those awards calculated under for either
      recognition or pro forma disclosures. Stock-based employee compensation
      expense for the six months ended June 30, 2006 was $12 and is included as
      an expense within the consolidated statements of operations, giving rise
      to a related tax benefit of $6. As of June 30, 2006, the total
      compensation cost related to non-vested awards not yet recognized was $104
      and the weighted-average period over which it is expected to be recognized
      was one year. There was no cumulative effect of initially adopting No.
      123R.

      The following table summarizes stock option activity for the six months
      ended June 30, 2006:



                                                                           WEIGHTED

      The total intrinsic value of options that vested during the six months
      ended June 30, 2005 and 2006 was $5 and $77, respectively.

      We granted 22,000 and 12,000 stock options during the six months ended
      June 30, 2005 and 2006, respectively. The weighted-average grant-date fair
      value of these options was $2.95 per share in the 2005 period and $5.45
      per share in the 2006 period. The fair value of stock options granted was
      estimated using a Black-Scholes valuation model with the following
      assumptions:



                                             Six months ended
                                                 June 30,

                                            ------      ------
                                                  
Risk-free interest rate                       3.69%       5.05%
Expected dividend yield                          0%          0%
Expected volatility                             69%         66%
Expected term (in years)                         3           3


      The risk-free interest rate assumptions were based upon the yield of a US
      Treasury interest only strip with a maturity date corresponding to the
      estimated term of the option. The expected volatility was based on
      historical bi-monthly price changes of our stock since July 1996. The
      estimated term was the average number of years that we estimate the
      options will be outstanding.

      In periods prior to January 1, 2006, we accounted for these plans under
      the recognition and measurement principles of Accounting Principles Board
      Opinion No. 25, "Accounting for Stock Issued to Employees," and related
      interpretations. No stock-based employee compensation cost was reflected
      in our statements of operations, as all options granted under these plans
      had an exercise price equal to the market value of the common stock on the
      date of the grant.

                                        8


      The following table illustrates the effect on net earnings and earnings
      per share if we had applied the fair value recognition provisions of No.
      123 to stock-based employee compensation. For purposes of pro forma
      disclosures, the estimated fair value of options is amortized to expense
      over the options' vesting periods.

      Although we do not have a formal policy for issuing shares upon exercise
      of stock options, these shares are generally issued from treasury stock.
      Based on current treasury stock levels, we do not expect to repurchase
      additional shares specifically for stock option exercises during 2006.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
            RESULTS OF OPERATIONS

INTRODUCTION

      Except for the historical information contained herein, the discussion in
this quarterly report on Form 10-Q contains forward-looking statements that
involve risk, assumptions, and uncertainties that are difficult to predict.
Words such as "anticipates," "believes," "estimates," "projects," "plans,"
"expects," "may," "could," "likely," variations of these words, and similar
expressions, are intended to identify such forward-looking statements. These
statements are made pursuant to the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. These statements are based upon the
current beliefs and expectations of our management and are subject to
significant risks and uncertainties. Actual results may differ from those set
forth in forward-looking statements. The following factors, among others, could
cause actual results to differ materially from those in forward-looking
statements: economic recessions or downturns in customers' business cycles;
excessive increases in capacity within truckload markets; surplus inventories;
decreased demand for transportation services offered by us; increases or rapid
fluctuations in inflation, interest rates, fuel prices, and fuel hedging; the
availability and costs of attracting and retaining qualified drivers and
owner-operators; failure to sustain profitability, which could result in
violation of bank covenants and acceleration of indebtedness at several
financial institutions; the ability to obtain financing on acceptable terms;
increases in insurance premiums and deductible amounts, or changes in excess
coverage, relating to accident, cargo, workers' compensation, health, and other
claims; the resale value of used equipment and prices of new equipment; seasonal
factors such as harsh weather conditions that increase operating costs;
regulatory requirements that increase costs and decrease efficiency, including
new emissions standards and hours-of-service regulations; changes in management;
and the ability to negotiate, consummate, and integrate acquisitions. Readers
should review and consider the various disclosures made by us in our press
releases, stockholder reports, and public filings, as well as the factors
explained in greater detail under "Risk Factors" and elsewhere in our annual
report on Form 10-K.

      Our fiscal year ends on December 31 of each year. Thus, this report
discusses the second quarter and first six months of our 2005 and 2006 fiscal
years.

      We generate substantially all of our revenue by transporting freight for
our customers. Generally, we are paid by the mile for our services. We also
derive revenue from fuel surcharges, loading and unloading activities, equipment
detention, and other accessorial services. The main factors that affect our
revenue are the revenue per mile we receive from our customers, the percentage
of miles for which we are compensated, and the number of miles we generate with
our equipment. These factors relate, among other things, to the United States
economy, inventory levels, the level of capacity in the trucking industry,
specific customer demand, and driver availability.

We monitor our revenue production primarily through average revenue per tractor
per week (excluding fuel surcharge, brokerage, and other revenues). We exclude
fuel surcharge, brokerage and other more volatile revenues in this measurement
because we believe the analysis of tractor productivity is more meaningful if
these revenues are excluded from the computation, providing useful information
to investors regarding business trends relating to our financial condition and
results of ongoing operations. The components of operating revenue are as
follows:

      During the second quarter of 2006, our average revenue per tractor per
week (excluding fuel surcharge, brokerage, and other revenues) increased to
$2,947 from $2,864 in the second quarter of 2005, reflecting a 4.5% increase in
our average revenue per loaded mile (excluding fuel surcharge, brokerage, and
other revenues) and a 1.6% increase in our weighted average tractors to 1,256 in
the 2006 quarter from 1,236 in the 2005 quarter. Our ending fleet size grew by
27 units (2.2%) to 1,261 units at June 30, 2006 compared to 1,234 units at June
30, 2005.

                                       10


      The main factors that impact our profitability on the expense side are the
variable costs of transporting freight for our customers. These costs include
fuel expense, driver-related expenses, such as wages, benefits, training, and
recruitment, and independent contractor costs, which are recorded under
purchased transportation. Expenses that have both fixed and variable components
include maintenance and tire expense and our total cost of insurance and claims.
These expenses generally vary with the miles we travel, but also have a
controllable component based on safety, fleet age, efficiency, and other
factors. Our main fixed costs are the acquisition and financing of long-term
assets, such as revenue equipment and the compensation of non-driver personnel.

      For the three months ended June 30, 2006, operating revenue increased
10.0% to $60.9 million from $55.4 million during the same quarter in 2005. Net
earnings were $1.6 million, or $0.31 per basic and diluted share, compared with
net earnings of $1.4 million, or $0.27 per basic share and diluted share, during
the 2005 quarter.

      For the six months ended June 30, 2006, operating revenue increased 12.8%
to $118.6 million from $105.1 million during the same period in 2005. Net
earnings were $2.6 million, or $0.52 per basic share and $0.51 per diluted
share, compared with net earnings of $1.9 million, or $0.38 per basic share and
$0.37 per diluted share, during the first six months of 2005.

COMPARISON OF THREE MONTHS ENDED JUNE 30, 2006 WITH THREE MONTHS ENDED JUNE 30,
2005.

      Operating revenue increased $5.5 million (10.0%) to $60.9 million in the
2006 quarter from $55.4 million in the 2005 quarter. The increase in operating
revenue resulted from increased average operating revenue per tractor per week
and an increase in our weighted average tractors to 1,256 in the 2006 quarter
from 1,236 in the 2005 quarter.

      Average operating revenue per tractor per week increased to $3,729 in the
2006 quarter from $3,445 in the 2005 quarter. Operating revenue includes revenue
from operating our trucks as well as other, more volatile revenue items,
including fuel surcharge, brokerage, and other revenue. We believe the analysis
of tractor productivity is more meaningful if fuel surcharge, brokerage, and
other revenue are excluded from the computation as this provides useful
information to investors regarding business trends relating to our financial
condition and results of ongoing operations. Average revenue per tractor per
week (excluding fuel surcharge, brokerage, and other revenue) increased to
$2,947 in the 2006 quarter from $2,864 in the 2005 quarter, primarily due to
improvements in our freight rates. Revenue per loaded mile (excluding fuel
surcharge, brokerage, and other revenue) increased $0.07 to $1.63 in the 2006
quarter from $1.56 in the 2005 quarter. Fuel surcharge revenue increased $3.5
million to $10.2 million in

                                       11


the 2006 quarter from $6.6 million in the 2005 quarter. During the second
quarter of 2006 and 2005, approximately $5.8 million and $3.9 million,
respectively, of the fuel surcharge revenue collected helped to offset our fuel
costs. The remainder was passed through to independent contractors.

      Purchased transportation consists primarily of payments to independent
contractor providers of revenue equipment, expenses related to brokerage
activities, and payments under operating leases of revenue equipment. Purchased
transportation increased $2.5 million (13.2%) to $21.7 million in the 2006
quarter from $19.1 million in the 2005 quarter. As a percentage of revenue,
purchased transportation increased to 35.6% in the 2006 quarter from 34.6% in
the 2005 quarter. The changes reflect higher pay to independent contractors
resulting from increases in fuel surcharge revenue and average revenue per
billed mile, higher payments to broker carriers and an increase in the
percentage of our fleet supplied by independent contractors. The percentage of
total operating revenue provided by independent contractors increased to 38.1%
in the 2006 quarter from 36.6% in the 2005 quarter.

      Compensation and employee benefits increased $102,000 (0.7%) to $14.7
million in the 2006 quarter from $14.6 million in the 2005 quarter reflecting
increases in the number of company drivers and in their rate of pay, as well as
increases in non-driver employee wages, that was partially offset by lower
health claims and worker's compensation expense. As a percentage of revenue,
compensation and employee benefits decreased to 24.1% in the 2006 quarter from
26.3% in the 2005 quarter, reflecting the changes described above and an
increase in our revenue per loaded mile and fuel surcharge revenue, which
increases revenue without a proportionate increase in wages. Our ratio of
tractors to non-driver employees, a key measure of administrative efficiency,
improved to 5.00 during the 2006 quarter compared to 4.91 in the 2005 quarter.
The market for recruiting drivers continues to be challenging. We increased
driver pay in April 2006 and expect that further increases will be necessary.
Future increases in driver pay will negatively impact our results of operations
to the extent that corresponding freight rate increases are not obtained.

      Fuel, supplies, and maintenance increased $2.2 million (18.8%) to $14.2
million in the 2006 quarter from $11.9 million in the 2005 quarter. As a
percentage of revenue, fuel, supplies, and maintenance increased to 23.3% of
revenue in the 2006 quarter compared with 21.6% in the 2005 quarter. This
reflects higher fuel prices, partially offset by an increase in our average
revenue per loaded mile, which increases revenue without a corresponding
increase in maintenance costs. As expected, maintenance costs have decreased as
we continue to update our fleet with new equipment. Fuel prices increased
approximately 28% to an average of $2.75 per gallon in the 2006 quarter from
$2.15 per gallon in the 2005 quarter. The $0.60 per gallon increase in fuel
prices was partially offset by a $0.46 per gallon ($2.0 million) increase in
fuel surcharge revenue attributable to company-owned tractors that is included
in operating revenue, mitigating 77% of the increase in fuel prices.

      Insurance and claims decreased $173,000 (10.4%) to $1.5 million in the
2006 quarter from $1.7 million in the 2005 quarter. As a percentage of revenue,
insurance and claims decreased to 2.4% of revenue in the 2006 quarter compared
with 3.0% in the 2005 quarter. This reflects a reduction in both primary and
excess insurance premiums, significantly lower auto liability, physical damage,
and cargo claims, and an increase in our average revenue per loaded mile, which
increases revenue without a corresponding increase in insurance and claims
costs. The insurance policies were renewed on July 1, 2006 with no material
change in coverage.

      Taxes and licenses were $1.0 million in both the 2006 quarter and 2005
quarter. As a percentage of revenue, taxes and licenses decreased to 1.7% of
revenue in the 2006 quarter compared with 1.9% of revenue in the 2005 quarter,
reflecting an increase in our average revenue per loaded mile and fuel surcharge
revenue, which increases revenue without a proportionate increase in taxes and
licenses.

      General and administrative expenses increased $202,000 (11.1%) to $2.0
million in the 2006 quarter from $1.8 million in the 2005 quarter, reflecting
increased advertising expense related to driver recruiting and the addition of
new agency relationships that has caused agent commissions to increase. As a
percentage of revenue, general and administrative expenses remained constant at
3.3% of revenue in both the 2006 quarter and 2005 quarter, reflecting the items
noted above offset by an increase in our average revenue per loaded mile and
fuel surcharge revenue, which increases revenue without a proportionate increase
in general and administrative expenses.

      Communications and utilities increased $8,000 (3.0%) to $273,000 in the
2006 quarter from $265,000 in the 2005 quarter. As a percentage of revenue,
communications and utilities decreased to 0.4% of revenue in the 2006 quarter
from 0.5% of revenue in the 2005 quarter, reflecting an increase in our average
revenue per loaded mile and fuel surcharge revenue which increases revenue
without a proportionate increase in communications and utilities expenses.

      Gains on the disposal of assets increased $270,000 (56.3%) to $750,000 in
the 2006 quarter from $480,000 in the 2005 quarter reflecting a stronger used
equipment market. As a percentage of revenue, gains on the disposal of assets
increased to 1.2% of revenue in the 2006 quarter compared to 0.9% of revenue in
the 2005 quarter.

      Depreciation and amortization increased $345,000 (12.9%) to $3.0 million
in the 2006 quarter from $2.7 million in the 2005 quarter reflecting an increase
in company owned tractors and trailers and an increase in the value of equipment
subject to depreciation. As a percentage of revenue, depreciation and
amortization increased to 4.9% of revenue in the 2006 quarter compared with 4.8%
in the 2005 quarter, reflecting the items noted above, the effect of which was
partially offset by an increase in our average revenue per loaded mile and fuel
surcharge revenue which increases revenue without a proportionate increase in
depreciation and amortization. As we continue to upgrade our equipment fleet, we
expect depreciation expense to increase.

      Interest expense, net, increased $117,000 (30.7%) to $498,000 in the 2006
quarter from $381,000 in the 2005 quarter. This increase was attributable to
higher average debt outstanding and higher interest rates. As a percentage of
revenue, interest expense, net, increased to 0.8% of revenue in the 2006 quarter
from 0.7% of revenue in the 2005 quarter.

      As a result of the foregoing, our pre-tax margin increased to 4.6% in the
2006 quarter from 4.2% in the 2005 quarter.

      Our income tax expense in the 2006 quarter was $1.2 million, or 43.9% of
earnings before income taxes. Our income tax expense in the 2005 quarter was
$990,000, or 42.2% of earnings before income taxes. In both quarters, the
effective tax rate was different from the expected combined tax rate for a
company headquartered in Iowa because a portion of the cost of driver per diem
expense is not deductible. The impact of paying per diem travel expenses varies
depending upon the ratio of drivers to independent contractors and the level of
our pre-tax earnings.

      As a result of the factors described above, net earnings were $1.6 million
in the 2006 quarter (2.6% of revenue), compared with $1.4 million in the 2005
quarter (2.4% of revenue). In addition, our operating ratio (operating expenses
as a percentage of operating revenue) was 94.6% during the 2006 quarter as
compared with 95.1% during the 2005 quarter. Our adjusted operating ratio
(operating expenses minus fuel surcharge revenue as a percentage of operating
revenue excluding fuel surcharge revenue) was 93.5% during the 2006 quarter as
compared with 94.4% during the 2005 quarter.

COMPARISON OF SIX MONTHS ENDED JUNE 30, 2006 WITH SIX MONTHS ENDED JUNE 30,
2005.

      Operating revenue increased $13.5 million (12.8%) to $118.6 million in the
first six months of 2006 from $105.1 million in first six months of 2005. The
increase in operating revenue resulted from increased average operating revenue
per tractor per week and an increase in our weighted average tractors to 1,262
in the 2006 period from 1,234 in the 2005 period.

      Average operating revenue per tractor per week increased to $3,614 in the
2006 period from $3,275 in the 2005 period. Operating revenue includes revenue
from operating our trucks as well as other, more volatile revenue items,
including fuel surcharge, brokerage, and other revenue. We believe the analysis
of tractor productivity is more meaningful if fuel surcharge, brokerage, and
other revenue are excluded from the computation as this provides useful
information to investors regarding business trends relating to our financial
condition and results of ongoing operations. Average revenue per tractor per
week (excluding fuel surcharge, brokerage, and other revenue) increased to
$2,881 in the 2006 period from $2,767 in the 2005 period, primarily due to
improvements in our freight rates. Revenue per loaded mile (excluding fuel
surcharge, brokerage, and other revenue) increased $0.08 to $1.62 in the 2006
period from $1.54 in the 2005 period. Fuel surcharge revenue increased $6.9
million to $18.4 million in the 2006 period from $11.5 million in the 2005
period. During the first six months of 2006 and 2005, approximately $10.5
million and $6.8 million, respectively, of the fuel surcharge revenue collected
helped to offset our fuel costs. The remainder was passed through to independent
contractors.

      Purchased transportation consists primarily of payments to independent
contractor providers of revenue equipment, expenses related to brokerage
activities, and payments under operating leases of revenue equipment. Purchased
transportation increased $6.7 million (18.9%) to $42.2 million in the 2006
period from $35.5 million in the 2005 period. As a percentage of revenue,
purchased transportation increased to 35.6% in the 2006 period from 33.8% in the
2005 period. The changes reflect higher pay to independent contractors resulting
from increases in fuel surcharge revenue and average revenue per billed mile,
higher payments to broker carriers and an increase in the percentage of our

                                       13


fleet supplied by independent contractors. The percentage of total operating
revenue provided by independent contractors increased to 37.6% in the 2006
period from 35.9% in the 2005 period.

      Compensation and employee benefits increased $1.6 million (5.6%) to $29.8
million in the 2006 period from $28.2 million in the 2005 period reflecting
increases in the number of company drivers and in their rate of pay, increases
in non-driver employee wages, and higher worker's compensation expense,
partially offset by lower health claims. As a percentage of revenue,
compensation and employee benefits decreased to 25.1% in the 2006 period from
26.9% in the 2005 period, reflecting the changes described above and an increase
in our revenue per loaded mile and fuel surcharge revenue, which increases
revenue without a proportionate increase in wages. Our ratio of tractors to
non-driver employees, a key measure of administrative efficiency, improved to
5.06 during the 2006 period compared to 4.94 in the 2005 period. The market for
recruiting drivers continues to be challenging. We increased driver pay in April
2006 and expect that further increases will be necessary. Future increases in
driver pay will negatively impact our results of operations to the extent that
corresponding freight rate increases are not obtained.

      Fuel, supplies, and maintenance increased $3.9 million (17.1%) to $26.9
million in the 2006 period from $23.0 million in the 2005 period. As a
percentage of revenue, fuel, supplies, and maintenance increased to 22.7% of
revenue in the 2006 period compared with 21.9% in the 2005 period. This reflects
higher fuel prices, partially offset by an increase in our average revenue per
loaded mile, which increases revenue without a corresponding increase in
maintenance costs. As expected, maintenance costs have decreased as we continue
to update our fleet with new equipment. Fuel prices increased approximately 25%
to an average of $2.56 per gallon in the 2006 period from $2.05 per gallon in
the 2005 period. The $0.51 per gallon increase in fuel prices was partially
offset by a $0.42 per gallon ($3.7 million) increase in fuel surcharge revenue
attributable to company-owned tractors that is included in operating revenue,
mitigating 82% of the increase in fuel prices.

      Insurance and claims decreased $748,000 (20.4%) to $2.9 million in the
2006 period from $3.7 million in the 2005 period. As a percentage of revenue,
insurance and claims decreased to 2.5% of revenue in the 2006 period compared
with 3.5% in the 2005 period. This reflects a reduction in both primary and
excess insurance premiums, significantly lower auto liability, physical damage,
and cargo claims, and an increase in our average revenue per loaded mile, which
increases revenue without a corresponding increase in insurance and claims
costs. The insurance policies were renewed on July 1, 2006 with no material
change in coverage.

      Taxes and licenses increased $61,000 (3.2%) to $2.0 million in the 2006
period from $1.9 million in the 2005 period. As a percentage of revenue, taxes
and licenses decreased to 1.7% of revenue in the 2006 period compared with 1.8%
of revenue in the 2005 period, reflecting an increase in our average revenue per
loaded mile and fuel surcharge revenue, which increases revenue without a
proportionate increase in taxes and licenses.

      General and administrative expenses increased $126,000 (3.3%) to $3.9
million in the 2006 period from $3.8 million in the 2005 period, reflecting
increased advertising expense related to driver recruiting and the addition of
new agency relationships that has caused agent commissions to increase. As a
percentage of revenue, general and administrative expenses decreased to 3.3% of
revenue in the 2006 period from 3.6% of revenue in the 2005 period, reflecting
the items noted above offset by an increase in our average revenue per loaded
mile and fuel surcharge revenue, which increases revenue without a proportionate
increase in general and administrative expenses.

      Communications and utilities increased $21,000 (3.5%) to $617,000 in the
2006 period from $596,000 in the 2005 period. As a percentage of revenue,
communications and utilities decreased to 0.5% of revenue in the 2006 period
from 0.6% of revenue in the 2005 period, reflecting an increase in our average
revenue per loaded mile and fuel surcharge revenue which increases revenue
without a proportionate increase in communications and utilities expenses.

      Gains on the disposal of assets increased $292,000 (28.6%) to $1.3 million
in the 2006 period from $1.0 million in the 2005 period reflecting a stronger
used equipment market. As a percentage of revenue, gains on the disposal of
assets increased to 1.1% of revenue in the 2006 period compared to 1.0% of
revenue in the 2005 period.

      Depreciation and amortization increased $531,000 (9.9%) to $5.9 million in
the 2006 period from $5.3 million in the 2005 period reflecting an increase in
company owned tractors and trailers and an increase in the value of equipment
subject to depreciation. As a percentage of revenue, depreciation and
amortization decreased to 5.0% of revenue in the 2006 period compared with 5.1%
in the 2005 period, reflecting the items noted above, the effect of which was
offset by an increase in our average revenue per loaded mile and fuel surcharge
revenue which increases revenue

                                       14


without a proportionate increase in depreciation and amortization. As we
continue to upgrade our equipment fleet, we expect depreciation expense to
increase.

      Interest expense, net, increased $264,000 (36.8%) to $981,000 in the 2006
period from $717,000 in the 2005 period. This increase was attributable to
higher average debt outstanding and higher interest rates. As a percentage of
revenue, interest expense, net, increased to 0.8% of revenue in the 2006 period
from 0.7% of revenue in the 2005 period.

      As a result of the foregoing, our pre-tax margin increased to 3.9% in the
2006 period from 3.2% in the 2005 period.

      Our income tax expense in the 2006 period was $2.0 million, or 44.0% of
earnings before income taxes. Our income tax expense in the 2005 period was $1.5
million, or 44.3% of earnings before income taxes. In both periods, the
effective tax rate was different from the expected combined tax rate for a
company headquartered in Iowa because a portion of the cost of driver per diem
expense is not deductible. The impact of paying per diem travel expenses varies
depending upon the ratio of drivers to independent contractors and the level of
our pre-tax earnings.

      As a result of the factors described above, net earnings were $2.6 million
in the 2006 period (2.2% of revenue), compared with $1.9 million in the 2005
period (1.8% of revenue). In addition, our operating ratio (operating expenses
as a percentage of operating revenue) was 95.3% during the 2006 period as
compared with 96.1% during the 2005 period. Our adjusted operating ratio
(operating expenses minus fuel surcharge revenue as a percentage of operating
revenue excluding fuel surcharge revenue) was 94.4% during the 2006 period as
compared with 95.7% during the 2005 period.

LIQUIDITY AND CAPITAL RESOURCES

      USES AND SOURCES OF CASH

      We require cash to fund working capital requirements and to service our
debt. We have historically financed acquisitions of new equipment with
borrowings under installment notes payable to commercial lending institutions
and equipment manufacturers, borrowings under lines of credit, cash flow from
operations, and equipment leases from third-party lessors. We also have obtained
a portion of our revenue equipment fleet from independent contractors who own
and operate the equipment, which reduces overall capital expenditure
requirements compared with providing a fleet of entirely company-owned
equipment.

      Our primary sources of liquidity have been funds provided by operations
and borrowings under credit arrangements with commercial lending institutions
and equipment manufacturers. At June 30, 2006, we had $4.5 million in cash and
adequate borrowing availability on our line of credit to finance any near-term
needs for working capital. During the first six months of 2006 we purchased 92
new tractors and 208 new trailers for $12.7 million, which was financed, in
part, with $10.9 million of new long term debt. We plan to purchase
approximately 118 new tractors and 182 new trailers throughout the remainder of
2006, allowing for the replacement of older, high mileage tractors and trailers.

      At June 30, 2006, we had positive working capital of $3.8 million compared
to positive working capital of $2.7 million at June 30, 2005. Working capital,
defined as current assets minus current liabilities, is not always fully
representative of our liquidity position because cash and trade receivables
account for a large portion of our current assets. Our trade accounts receivable
are generally collected within 31 days. Alternatively, current maturities of
long term debt, a large portion of our current liabilities, are paid over one
year.

      Our ability to fund cash requirements in future periods will depend on our
ability to comply with covenants contained in financing arrangements and the
availability of other financing options, as well as our financial condition and
results of operations. Our financial condition and results of operations will
depend on insurance and claims experience, general shipping demand by our
customers, fuel prices, the availability of drivers and independent contractors,
the continued success of our profit improvement plan, and other factors.

      Although there can be no assurance, we believe that cash generated by
operations and available sources of financing for acquisitions of revenue
equipment will be adequate to meet our currently anticipated working capital
requirements and other cash needs through June 2007. We will require additional
sources of financing over the long-term to upgrade our tractor and trailer
fleets. To the extent that actual results or events differ from our financial
projections or business plans, our liquidity may be adversely affected and we
may be unable to meet our financial covenants.

                                       15


Specifically, our short- and long-term liquidity may be adversely affected by
one or more of the following factors: costs associated with insurance and
claims; weak freight demand or a loss in customer relationships or volume; the
impact of new hours-of-service regulations on asset productivity; the impact of
stricter emissions standards; the ability to attract and retain sufficient
numbers of qualified drivers and independent contractors; elevated fuel prices
and the ability to collect fuel surcharges; inability to maintain compliance
with, or negotiate amendments to, loan covenants; the ability to finance the
tractors and trailers delivered and scheduled for delivery; and the possibility
of shortened payment terms by our suppliers and vendors worried about our
ability to meet payment obligations. Based upon our profitability, anticipated
future cash flows, current availability under the financing arrangement with
LaSalle Bank, and sources of equipment financing that are available, we do not
expect to experience significant liquidity constraints in the foreseeable
future. To the extent that actual results or events differ from our financial
projections or business plans, our liquidity may be adversely affected and we
may be unable to meet our financial covenants. In such event, we believe we
could renegotiate the terms of our debt or that alternative financing would be
available, although this cannot be assured.

      Net cash provided by operating activities was $8.4 million for the six
months ended June 30, 2006, compared to $6.7 million for the six months ended
June 30, 2005. Historically, our principal use of cash from operations is to
service debt and to internally finance acquisitions of revenue equipment. Total
receivables increased $1.4 million for the six months ended June 30, 2006. The
average age of our trade accounts receivable improved to 30.9 days in the 2006
period compared to 31.6 days in the 2005 period.

      Net cash provided by investing activities was $1.4 million for the six
months ended June 30, 2006. This related primarily to proceeds from the sale of
revenue equipment offset by the use of cash to purchase property and equipment.

      Net cash used in financing activities was $5.6 million for the six months
ended June 30, 2006, consisting primarily of net payments of principal under our
long-term debt agreements.

      We have a financing arrangement with LaSalle Bank, which expires on
October 31, 2010, and provides for automatic month-to-month renewals under
certain conditions after that date. LaSalle Bank may terminate the arrangement
prior to October 31, 2010, in the event of default, and may terminate at the end
of any renewal term. The agreement provides for a revolving line of credit which
allows for borrowings at up to 85% of eligible receivables. At June 30, 2006,
there was no balance owed under our revolving line of credit.

      The LaSalle Bank financing arrangement also includes financing for letters
of credit. At June 30, 2006, we had outstanding letters of credit totaling $7.6
million for self-insured amounts under our insurance programs. We are required
to pay an annual fee of 1.25% of the outstanding letters of credit. These
letters of credit directly reduce the amount of potential borrowings available
under the financing arrangement discussed above. Any increase in self-insured
retention, as well as increases in claim reserves, may require additional
letters of credit to be posted, which would negatively affect our liquidity.

      The combination of borrowings under the line of credit and outstanding
letters of credit with LaSalle Bank cannot exceed the lower of $15 million or a
specified borrowing base, which at June 30, 2006 was $15.0 million, leaving $7.4
million in remaining availability at such date. We are required to pay a
facility fee on the LaSalle Bank financing arrangement of .20% of the unused
loan limit. Borrowings under the arrangement are secured by accounts receivable.
The interest rate on outstanding borrowings under the arrangement is equal to a
spread on LaSalle Bank's prime rate or LIBOR, at our option. The spread is
determined by our ratio of funded debt to earnings before interest, taxes,
depreciation, amortization and rent, or EBITDAR, as defined under the agreement.
At June 30, 2006 the applicable interest rate under the arrangement was equal to
the prime rate minus 75 basis points.

      The LaSalle Bank financing arrangement requires compliance with certain
financial covenants, including compliance with a minimum tangible net worth,
debt to EBITDAR, and a fixed charge coverage ratio. We were in compliance with
these requirements at June 30, 2006. We believe we will maintain compliance with
all covenants throughout 2006, although there can be no assurance that the
required financial performance will be achieved. In addition, equipment
financing provided by a manufacturer contains a minimum tangible net worth
requirement. We were in compliance with the required minimum tangible net worth
requirement for June 30, 2006 and we expect to remain in compliance for the
foreseeable future. If we fail to maintain compliance with these financial
covenants, or to obtain a waiver of any noncompliance, the lenders will have the
right to declare all sums immediately due and pursue other remedies. In this
event, we believe we could renegotiate the terms of our debt or that alternative
financing would be available, although this cannot be assured. As of the filing
date, we were in compliance with all financial covenants.

      In our normal course of business we place orders with equipment
manufacturers for future delivery of new tractors and trailers. The orders for
trailers can be cancelled at any time without penalty prior to taking delivery.
The orders for tractors can be cancelled without penalty at any time up to 60
days prior to production of the tractor. If the termination occurs less than 60
days, but more than 45 days prior to production, we retain the right to cancel
subject to a per truck penalty of $500. Orders generally cannot be cancelled
within 45 days prior to production. At June 30, 2006, we had commercial
commitments of approximately $4.8 million, related to tractor and trailer orders
that cannot be cancelled. Financing for these commitments has been prearranged.

      Approximately 19% of our long-term debt carries a variable interest rate
making reliable estimates of future interest payments difficult. Using our
weighted average interest rate of 6.45% as of June 30, 2006, the following
approximately represents our expected obligations for future interest payments:

      We had no other commercial commitments at June 30, 2006.

OFF-BALANCE SHEET ARRANGEMENTS

      Our liquidity is not materially affected by off-balance sheet
transactions. As of June 30, 2006, our fleet included 126 tractors and 11
trailers obtained under operating leases. The lease payments for these tractors
and trailers increase equipment rent expense, a component of purchased
transportation expense, rather than depreciation and interest expense. These
obligations are included in our schedule of contractual obligations, and exclude
potential Terminal Remainder Adjustment Clause (TRAC) payments or refunds on 116
tractors amounting to 40% of the original purchase price due at the end of the
original 48 month term of the lease. After 48 months, we expect the residual
value of the tractors to be greater than 40% of the original cost, allowing us
to return the tractors without penalty.

                                       17


CRITICAL ACCOUNTING POLICIES

      The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires us to make decisions based upon
estimates, assumptions, and factors we consider as relevant to the
circumstances. Such decisions include the selection of applicable accounting
principles and the use of judgment in their application, the results of which
impact reported amounts and disclosures. Changes in future economic conditions
or other business circumstances may affect the outcomes of our estimates and
assumptions. Accordingly, actual results could differ from those anticipated. A
summary of the significant accounting policies followed in preparation of the
financial statements included in this Form 10-Q is contained in Note 1 of the
consolidated financial statements included in our Form 10-K for the year ended
December 31, 2005. Other footnotes in the Form 10-K describe various elements of
the financial statements included in this Form 10-Q and the assumptions on which
specific amounts were determined.

      Our critical accounting policies include the following:

      REVENUE RECOGNITION

      We generally recognize operating revenue when the freight to be
transported has been loaded. We operate primarily in the short-to-medium length
haul category of the trucking industry; therefore, our typical customer delivery
is completed one day after pickup. Accordingly, this method of revenue
recognition is not materially different from recognizing revenue based on
completion of delivery. We recognize operating revenue when the freight is
delivered for longer haul loads where delivery is completed more than one day
after pickup. Amounts payable to independent contractors for purchased
transportation, to company drivers for wages, and other direct expenses are
accrued when the related revenue is recognized.

      PROPERTY AND EQUIPMENT

      Property and equipment are recorded at cost. Depreciation is provided by
use of the straight-line and declining-balance methods over lives of 5 to 39
years for buildings and improvements, 5 years for tractors, 7 years for
trailers, and 3 to 10 years for other equipment. Tires purchased as part of
revenue equipment are capitalized as a cost of the equipment. Replacement tires
are expensed when placed in service. Expenditures for maintenance and minor
repairs are charged to operations, and expenditures for major replacements and
betterments are capitalized. The cost and related accumulated depreciation on
property and equipment retired, traded, or sold are eliminated from the property
accounts at the time of retirement, trade, or sale. The gain or loss on
retirement or sale is recognized in accordance with Statement of Financial
Accounting Standards No. 153, "Exchange of Nonmonetary Assets" (SFAS 153).

      ESTIMATED LIABILITY FOR INSURANCE CLAIMS

      Losses resulting from auto liability, physical damage, workers'
compensation, and cargo loss and damage are covered by insurance subject to
certain self-retention levels. Losses resulting from uninsured claims are
recognized when such losses are incurred. We estimate and accrue a liability for
our share of ultimate settlements using all available information. We accrue for
claims reported, as well as for claims incurred but not reported, based upon our
past experience. Expenses depend on actual loss experience and changes in
estimates of settlement amounts for open claims that have not been fully
resolved. However, final settlement of these claims could differ materially from
the amounts we have accrued at year-end. Our judgment concerning the ultimate
cost of claims and modification of initial reserved amounts is an important part
of establishing claims reserves, and is of increasing significance with higher
self-insured retention and lack of excess coverage.

      IMPAIRMENT OF LONG-LIVED ASSETS

      Long-lived assets are reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net undiscounted cash
flows expected to be generated by the asset. Our judgment concerning future cash
flows is an important part of this determination. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by
which the carrying amount of the assets exceeds the fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying amount or
fair value less the costs to sell.

      ACCOUNTING STANDARDS

      In February 2006, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 155, "Accounting for Certain Hybrid Financial Instruments-An Amendment
of FASB Statements No. 133 and 140." This statement amends FASB Statements No.
133, "Accounting for Derivative Instruments and Hedging Activities," and No.
140, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities" and eliminates the exemption from applying
Statement No. 133 to interests in securitized financial assets so that similar
items are accounted for in the same way. The provisions of SFAS No. 155 are
effective for all financial instruments acquired or issued after the beginning
of the first fiscal year that begins after September 15, 2006. As of June 30,
2006, we believe that SFAS No. 155 will have no effect on our financial
position, results of operations, and cash flows.

      In March 2006, the FASB issued SFAS No. 156, "Accounting for Servicing of
Financial Assets-An Amendment of FASB Statement No. 140." This Statement amends
FASB Statement No. 140, "Accounting for Transfers and Servicing of Financial
Assets and Extinguishments of Liabilities" and requires that all separately
recognized servicing assets and servicing liabilities be initially measured at
fair value, if practicable. The provisions of SFAS No. 156 are effective as of
the beginning of the first fiscal year that begins after September 15, 2006. As
of June 30, 2006, we believe that SFAS No. 156 will have no effect on our
financial position, results of operations, and cash flows.

      In July 2006, the FASB issued FASB Interpretation No. 48 ("FIN 48"),
"Accounting for Uncertainty in Income Taxes-an Interpretation of FASB Statement
No. 109." This interpretation prescribes a recognition threshold and measurement
process for recording in the financial statements uncertain tax positions taken
or expected to be taken in a tax return. Additionally, this interpretation
provides guidance on the derecognition, classification, accounting in interim
periods, and disclosure requirements for uncertain tax positions. The provisions
of FIN 48 will be effective at the beginning of the first fiscal year that
begins after December 15, 2006. We are evaluating the effect, if any, the
adoption of FIN 48 will have on our financial statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      We are exposed to a variety of market risks, most importantly the effects
of the price and availability of diesel fuel and changes in interest rates.

COMMODITY PRICE RISK

      Our operations are heavily dependent upon the use of diesel fuel. The
price and availability of diesel fuel can vary and are subject to political,
economic, and market factors that are beyond our control. Significant increases
in diesel fuel prices could materially and adversely affect our results of
operations and financial condition.

      We presently use fuel surcharges to address the risk of increasing fuel
prices. We believe these fuel surcharges are an effective means of mitigating
the risk of increasing fuel prices, although the competitive nature of our
industry prevents us from recovering the full amount of fuel price increases
through the use of these surcharges.

      In the past, we have used derivative instruments, including heating oil
price swap agreements, to reduce a portion of our exposure to fuel price
fluctuations. Since 2000, we have had no such agreements in place. We do not
trade in these derivatives with the objective of earning financial gains on
price fluctuations.

INTEREST RATE RISK

      We also are exposed to market risks from changes in certain interest rates
on our debt. Our financing arrangement with LaSalle Bank carries a variable
interest rate equal to a spread on LaSalle's prime rate or LIBOR, at our option.
The spread is determined by our ratio of funded debt to EBITDAR, as defined
under the agreement. In addition, approximately $7.4 million of our other debt
carries variable interest rates. This variable interest exposes us to the risk
that interest rates may rise. Assuming borrowing levels at June 30, 2006, a
one-point increase in the prime rate would increase interest expense by
approximately $74,000. The remainder of our other debt carries fixed interest
rates. At June 30, 2006, approximately 19% of our debt carried a variable
interest rate and the remainder was fixed.

                                       19


ITEM 4. CONTROLS AND PROCEDURES

      As required by Rule 13a-15 under the Securities Exchange Act of 1934 (the
"Exchange Act"), we have carried out an evaluation of the effectiveness of the
design and operation of our disclosure controls and procedures (as defined in
Exchange Act Rule 13a-15(e)) as of the end of the period covered by this report.
This evaluation was carried out under the supervision and with the participation
of our management, including our Chief Executive Officer and our Chief Financial
Officer. Based upon that evaluation, our Chief Executive Officer and our Chief
Financial Officer concluded that our disclosure controls and procedures were
effective as of June 30, 2006. During our second fiscal quarter, there were no
changes in our internal control over financial reporting that have materially
affected, or that are reasonably likely to materially affect, our internal
control over financial reporting. We intend to periodically evaluate our
disclosure controls and procedures as required by the Exchange Act rules.

      Disclosure controls and procedures are controls and other procedures that
are designed to ensure that information required to be disclosed in our reports
filed or submitted under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the Securities and Exchange
Commission's rules and forms. Disclosure controls and procedures include
controls and procedures designed to ensure that information required to be
disclosed in our reports filed under the Exchange Act is accumulated and
communicated to management, including our Chief Executive Officer and Chief
Financial Officer, as appropriate, to allow timely decisions regarding
disclosures.

      We have confidence in our disclosure controls and procedures and internal
controls and procedures. Nevertheless, our management, including our Chief
Executive Officer and our Chief Financial Officer, does not expect that our
disclosure controls and procedures or our internal controls will prevent all
errors or intentional fraud. A disclosure control system and an internal control
system, no matter how well conceived and operated, can provide only reasonable,
not absolute, assurance that the objectives of these controls are met. Further,
the design of these control systems must reflect the fact that there are
resource constraints, and the benefits of controls must be considered relative
to their costs. Because of the inherent limitations in all control systems, no
evaluation of controls can provide absolute assurance that all control issues
and instances of fraud, if any, within our company have been detected.
