         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. FINANCIAL INFORMATION

The  accompanying   condensed  consolidated  financial  statements  include  the
accounts of Knight Transportation,  Inc., and its wholly owned subsidiaries (the
Company).  All  material  inter-company  balances  and  transactions  have  been
eliminated in consolidation.

The condensed  consolidated  financial  statements included herein are unaudited
and have been  prepared  in  accordance  with  accounting  principles  generally
accepted  in the United  States of America  ("GAAP"),  pursuant to the rules and
regulations of the Securities and Exchange  Commission.  Certain information and
footnote  disclosures have been omitted or condensed  pursuant to such rules and
regulations. In the opinion of management, all adjustments (consisting of normal
recurring  adjustments)  considered  necessary for a fair presentation have been
included.   Results  of  operations  in  interim  periods  are  not  necessarily
indicative of results for a full year.  These condensed  consolidated  financial
statements and notes thereto  should be read in  conjunction  with the Company's
consolidated  financial  statements and notes thereto  included in the Company's
Annual Report on Form 10-K for the year ended December 31, 2002.

The  preparation  of  financial  statements  in  accordance  with GAAP  requires
management to make estimates and  assumptions.  Such  estimates and  assumptions
affect the reported  amounts of assets and  liabilities as well as disclosure of
contingent  assets and liabilities,  at the date of the  accompanying  condensed
consolidated financial statements,  and the reported amounts of the revenues and
expenses  during the reporting  periods.  Actual results could differ from those
estimates.

NOTE 2. STOCK BASED COMPENSATION

Stock-Based  Compensation  - At June 30, 2003,  the Company had one  stock-based
employee compensation plan. The Company applies the intrinsic-value-based method
of accounting  prescribed by Accounting  Principles  Board (APB) Opinion No. 25,
"Accounting  for  Stock  Issued  to  Employees,"  and  related   interpretations
including  FASB  Interpretation  No. 44,  "Accounting  for Certain  Transactions
involving Stock  Compensation,  an interpretation of APB Opinion No. 25," issued
in March 2000, to account for its fixed-plan  stock options.  Under this method,
compensation expense is recorded on the date of grant only if the current market
price of the  underlying  stock  exceeded the  exercise  price.  No  stock-based
employee  compensation  cost is reflected in net income,  as all options granted
under the plan had an exercise price equal to the market value of the underlying
common stock on the date of the grant. SFAS No. 123, "Accounting for Stock-Based
Compensation,"  as  amended  by  SFAS  No.  148,   "Accounting  for  Stock-Based
Compensation - Transition and Disclosure," established accounting and disclosure
requirements  using a  fair-value-based  method of  accounting  for  stock-based
employee compensation plans. As allowed by SFAS No. 123, the Company has elected
to continue to apply the  intrinsic-value-based  method of accounting  described
above,  and has adopted only the  disclosure  requirements  of SFAS No. 123. The
following  table  illustrates  the effect on net income if the  fair-value-based
method had been applied to all outstanding and unvested awards for the three and
six-month  periods ended June 30, 2003 and 2002 (in thousands,  except per share
data):

The fair value of each option  grant is estimated on the date of the grant using
the  Black-Scholes  option  pricing  model with the following  weighted  average
assumptions  used for grants in 2003;  risk free interest  rate 3.36%;  expected
life of six years;  expected  volatility of 51%; expected dividend yield rate of
zero,  and  expected  forfeitures  of  4.27%.  The  following  weighted  average
assumptions  were  used for  grants  in 2002;  risk free  interest  rate  3.36%;
expected life of six years;  expected volatility of 52%; expected dividend yield
rate of zero, and expected forfeitures of 3.04%.

NOTE 5. SEGMENT INFORMATION

Although we have eleven operating segments,  we have determined that we have one
reportable  segment.  Ten of the  segments  are managed  based on regions in the
United States in which we operate.  Each of these segments has similar  economic
characteristics  as they all  provide  short to  medium-haul  truckload  carrier
services of general  commodities  to a similar class of customers.  In addition,
each segment exhibits similar financial  performance,  including average revenue
per mile and operating ratio.  The remaining  segment is not reported because it
does not meet the  materiality  thresholds in Statement of Financial  Accounting
Standards (SFAS) No. 131. As a result, we have determined that it is appropriate
to aggregate our operating divisions into one reportable segment consistent with
the  guidance  in SFAS No.  131.  Accordingly,  we have not  presented  separate
financial  information for each of our operating  divisions as our  consolidated
financial statements present our one reportable segment.

NOTE 6. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

All  derivatives are recognized on the balance sheet at their fair value. On the
date the  derivative  contract is entered into,  we designate the  derivative as
either a hedge of the fair value of a  recognized  asset or  liability  or of an
unrecognized  firm  commitment  ("fair  value"  hedge),  a hedge of a forecasted
transaction or the variability of cash flows to be received or paid related to a
recognized asset or liability ("cash flow" hedge), a foreign-currency fair-value
or cash-flow hedge ("foreign currency" hedge), or a hedge of a net investment in
a foreign operation. We formally assess, both at the hedge's inception and on an
ongoing basis, whether the derivatives that are used in hedging transactions are
effective in  offsetting  changes in fair values or cash flows of hedged  items.
When it is  determined  that a derivative is not effective as a hedge or that it
has  ceased  to  be  an  effective   hedge,  we  discontinue   hedge  accounting
prospectively.

In  August  and  September  2000,  and in  July  2001,  we  entered  into  three
agreements,  respectively,  which are designated as derivative contracts.  These
three contracts  relate to the price of heating oil on the New York  Merchantile
Exchange  ("NYMX") and were entered into in  connection  with volume diesel fuel
purchases between October 2000 and February 2002. The three agreements described
above are  stated  at their  fair  market  value in the  accompanying  condensed
consolidated financial statements.

During  2001,  we entered  into an  interest  rate swap  agreement  on the $12.2
million  outstanding on our line of credit for purposes of better  managing cash
flow. On November 7, 2001, we paid $762,500 to settle this swap  agreement.  The
amount is  included  in other  comprehensive  income and is being  amortized  to
interest expense over the original 36-month term of the swap agreement.

NOTE 7. RECENTLY ADOPTED AND TO BE ADOPTED ACCOUNTING PRONOUNCEMENTS

In June 2001,  the FASB issued SFAS No. 143,  "Accounting  for Asset  Retirement
Obligations"  (SFAS No.  143).  SFAS No. 143  requires the Company to record the
fair value of an asset  retirement  obligation  as a liability  in the period in
which it incurs a legal  obligation  associated  with the retirement of tangible
long-lived  assets that result from the acquisition,  construction,  development
and/or normal use of the assets. The Company also records a corresponding  asset
which is  depreciated  over the life of the  asset.  Subsequent  to the  initial
measurement of the asset retirement obligation,  the obligation will be adjusted
at the end of each  period to reflect  the  passage  of time and  changes in the
estimated future cash flows underlying the obligation.  The Company adopted SFAS
No. 143 on January 1, 2003. The adoption of SFAS No. 143 did not have a material
impact on our consolidated financial statements.

                                        9

In June 2002,  the FASB issued SFAS No.  146,  "Accounting  for Exit or Disposal
Activities" (SFAS No. 146). SFAS No. 146 addresses the recognition,  measurement
and reporting of costs associated with exit and disposal  activities,  including
restructuring  activities.  SFAS No. 146 also  addresses  recognition of certain
costs related to terminating a contract that is not a capital lease, recognition
of costs to  consolidate  facilities or relocate  employees and  recognition  of
costs for termination of benefits  provided to employees that are  involuntarily
terminated  under the terms of a  one-time  benefit  arrangement  that is not an
ongoing benefit  arrangement or an individual  deferred  compensation  contract.
SFAS No. 146 is effective  for exit or disposal  activities  that are  initiated
after  December 31,  2002.  The adoption of SFAS No. 146 did not have a material
impact on our consolidated financial statements.

In November 2002, the FASB issued Interpretation No. 45, "Guarantor's Accounting
and Disclosure  Requirements for Guarantees,  Including  Indirect  Guarantees of
Indebtedness to Others,  an  interpretation of FASB Statements No. 5, 57 and 107
and a rescission of FASB Interpretation No. 34." This interpretation  elaborates
on the disclosures to be made by a guarantor in its interim and annual financial
statements about its obligations under guarantees  issued.  This  interpretation
also  clarifies  that a guarantor  is required to  recognize  at  inception of a
guarantee,  a liability  for the fair value of the  obligation  undertaken.  The
initial  recognition  and  measurement  provisions  of this  interpretation  are
applicable to guarantees issued or modified after December 31, 2002, and are not
expected to have a material effect on our consolidated financial statements. The
disclosure  requirements  are effective for financial  statements of interim and
annual  periods  ending  after  December  31,  2002.  The  application  of  this
interpretation  did not have a  material  effect on our  consolidated  financial
statements.

In January  2003,  the FASB  issued  Interpretation  No. 46,  "Consolidation  of
Variable   Interest   Entities,   an   interpretation   of  ARB  No.  51."  This
interpretation  addresses the consolidation by business  enterprises of variable
interest entities as defined in this interpretation. This interpretation applies
immediately to variable  interests in variable  interest  entities created after
January 31,  2003,  and to variable  interests  in  variable  interest  entities
obtained after January 31, 2003. For public enterprises with a variable interest
in  a  variable   interest   entity  created  before   February  l,  2003,  this
interpretation  applies to that  enterprise  no later than the  beginning of the
first interim or annual  reporting  period  beginning  after June 15, 2003.  The
application of this  interpretation is not expected to have a material effect on
our consolidated financial statements.

In April,  2003, the Financial  Accounting  Standards Board issued SFAS No. 149,
"Amendment of Statement 133 on Derivative  Instruments and Hedging  Activities."
SFAS No.  149  amends and  clarifies  financial  accounting  and  reporting  for
derivative  instruments  embedded in other contracts and for hedging  activities
under  SFAS  No.  133,  "Accounting  for  Derivative   Instruments  and  Hedging
Activities."  It is effective for contracts  entered into or modified after June
30,  2003,  except  as stated  within  the  statement,  and  should  be  applied
prospectively.  We do not expect this statement to have a material effect on our
consolidated financial statements.

On May 15, 2003, the Financial  Accounting  Standards Board issued SFAS No. 150,
"Accounting  for Certain  Financial  Instruments  with  Characteristics  of Both
Liabilities  and  Equity."  SFAS  No.  150  requires   issuers  to  classify  as
liabilities  (or assets in some  circumstances)  three  classes of  freestanding
financial  instruments that embody obligations for the issuer.  Generally,  SFAS
No. 150 is effective for financial  instruments  entered into or modified  after
May 31, 2003 and is otherwise  effective at the  beginning of the first  interim
period  beginning after June 15, 2003. We adopted the provisions of SFAS No. 150
on July 1, 2003.  We did not enter  into any  financial  instruments  within the
scope of the SFAS No. 150 during June 2003.

NOTE 8. COMMITMENTS AND CONTINGENCIES

We are involved in certain  legal  proceedings  arising in the normal  course of
business.  In the opinion of  management,  our potential  exposure under pending
legal  proceedings  is  adequately  provided for in the  accompanying  condensed
consolidated financial statements.

any forward-looking statement contained in this Quarterly Report.

OVERVIEW

We are a dry van  truckload  carrier  based in Phoenix,  Arizona.  We  transport
general  commodities  for  shippers  throughout  the  United  States,  generally
focusing our operations on short-to-medium  lengths of haul in our ten operating
regions.  Over the past five  years we have  achieved  substantial  growth  from
$125.0  million in revenue,  before  fuel  surcharge,  and $13.3  million in net
income in 1998 to $279.3 million in revenue,  before fuel  surcharge,  and $27.9
million in net income in 2002.  The main factors that affect our results are the
number of tractors we operate, our revenue per tractor (which includes primarily
our revenue per total mile and our number of miles per tractor), and our ability
to control our costs.

For the  quarter  ended June 30,  2003,  our  revenue,  before  fuel  surcharge,
increased  19.7% to $81.8  million  from $68.3  million for the same  quarter of
2002.  Net income  increased  33.5% to $8.9 million from $6.7  million,  and net
income per  diluted  share  increased  to $0.23  from  $0.18.  The main  factors
contributing to the improvement  were a 15.9% increase in average tractors and a
3.3% increase in revenue per tractor  versus the 2002  quarter.  We expanded our
business geographically and increased our volume in existing territories.  These
factors more than offset  higher costs of  insurance,  maintenance  and fuel. We
ended the quarter with $37.2  million in cash and $13.0  million in  borrowings.
Our shareholders' equity was $218.7 million.

                                       11

NOTE REGARDING REVENUE AND EXPENSES

Our total  revenue for the three months ended June 30, 2003,  increased to $85.1
million from $69.8 million for the same period in 2002.  Total revenue  included
$3.3  million of fuel  surcharge  revenue in the 2003 period and $1.5 million of
fuel  surcharge  revenue  in the 2002  period.  In  discussing  our  results  of
operations we use revenue,  before fuel  surcharge,  (and fuel  expense,  net of
surcharge,)  because we believe that eliminating this sometimes  volatile source
of  revenue  affords  a more  consistent  basis for  comparing  our  results  of
operations from period to period. We also discuss the changes in our expenses as
a percentage of revenue,  before fuel  surcharge,  rather than  absolute  dollar
changes.  We do this  because we believe  the high  variable  cost nature of our
business  makes a comparison  of changes in expenses as a percentage  of revenue
more meaningful than absolute changes.

RESULTS OF OPERATIONS

Our  revenue,  before fuel  surcharge,  for the six months  ended June 30, 2003,
increased by 19.3% to $155.3  million from $130.2 million for the same period in
2002. For the three months ended June 30, 2003, revenue,  before fuel surcharge,
increased by 19.7% to $81.8  million  from $68.3  million for the same period in
2002. The increase in revenue,  before fuel surcharge,  for the first six months
of 2003  resulted  primarily  from a 14.9%  increase  in average  tractors as we
expanded  our  geographic  coverage  and  increased  our  business  in  existing
territories,  as well as a 3.8%  increase  in revenue  per  average  tractor.  A
significant  increase in our revenue per tractor was accomplished from increased
revenue  per mile  resulting  from our sales  efforts and a market that was more
receptive to rate increases. Although it is our goal to improve revenue per mile
over time, we do not expect our  improvement in revenue per mile versus the same
period last year to continue  at the same level  because we believe  revenue per
mile for the first half of 2002 was at a low base.

Salaries,  wages and benefits decreased as a percentage of revenue,  before fuel
surcharge,  to 32.3% for the six months ended June 30, 2003,  from 33.9% for the
same period in 2002. For the three months ended June 30, 2003,  salaries,  wages
and benefits  decreased as a percentage of revenue,  before fuel  surcharge,  to
32.3% from 33.6% for the same period in 2002. These decreases were primarily the
result of increased  revenue per mile, which increased the revenue generated per
tractor without an increase in the miles for which our drivers were compensated.
Our cost of health  insurance  and  worker's  compensation  programs,  which are
included in salaries,  wages and  benefits,  remained  relatively  constant as a
percentage of revenue between the two periods.

Fuel  expense,  net of fuel  surcharge,  decreased as a  percentage  of revenue,
before fuel surcharge, to 13.4% for the six months ended June 30, 2003, compared
to 13.6% for the same period in 2002.  For the three months ended June 30, 2003,
fuel expense as a percentage  of revenue,  before fuel  surcharge,  decreased to
12.6% from 13.5% for the same period in 2002. These decreases were primarily the
result of increases in revenue per mile.  Independent  contractors pay their own
fuel costs.

Operations and maintenance expense increased as a percentage of revenue,  before
fuel surcharge, to 6.3% for the six months ended June 30, 2003 from 5.7% for the
same period in 2002.  For the three months ended June 30, 2003,  operations  and
maintenance expense increased as a percentage of revenue, before fuel surcharge,
to 6.2%  compared  to 6.0% for the same  period in 2002.  These  increases  were
primarily due to increased tire expenses and increased  maintenance expenses due
to the aging of our fleet.

                                       12

Insurance and claims expense  increased as a percentage of revenue,  before fuel
surcharge,  to 5.2% for the six months  ended June 30,  2003,  from 4.4% for the
same period in 2002.  For the three months ended June 30,  2003,  insurance  and
claims expense increased as a percentage of revenue,  before fuel surcharge,  to
5.2%  from 4.4% for the same  period  in 2002.  The  primary  reasons  for these
increases were higher insurance  premiums and an increase in our  self-insurance
retention level.  Based on our current  insurance  policies and experience,  and
assuming the absence of any  catastrophic  events,  we expect our  insurance and
claims  expense  to be  approximately  4.7%  to  5.3% of  revenue,  before  fuel
surcharge, for the next several quarters.

Operating taxes and licenses  decreased as a percentage of revenue,  before fuel
surcharge,  to 2.8% for the six months  ended June 30,  2003,  from 2.9% for the
same period in 2002.  These  decreases were primarily due to increase in revenue
per mile. For the three months ended June 30, 2003, operating taxes and licenses
as  a  percentage  of  revenue,  before  fuel  surcharge,   remained  relatively
consistent at 2.8% for both the 2003 and 2002 periods.

Communications  expense as a percentage of revenue,  before fuel surcharge,  for
both the six months and three months ended June 30,  2003,  remained  relatively
consistent with the same periods in 2002, at less than 1.0% of revenue.

Depreciation  and amortization  expense as a percentage of revenue,  before fuel
surcharge,  increased to 9.0% for the six month period ended June 30, 2003, from
8.4% for the same  period in 2002.  For the three  months  ended June 30,  2003,
depreciation and amortization increased as a percentage of revenue,  before fuel
surcharge,  to 8.9% from 8.1% for the same period in 2002.  These increases were
primarily  related  to the  increase  in the ratio of  purchased  vehicles  as a
percentage of total vehicles in our fleet.  Our total fleet  includes  purchased
vehicles,  vehicles  acquired under  operating  lease  agreements,  and vehicles
provided by independent contractors.

Lease  Expense -  revenue  equipment  as  percentage  of  revenue,  before  fuel
surcharge, was 2.5% for the six months ended June 30, 2003, compared to 3.5% for
the same period in 2002.  For the three months ended June 30, 2003 Lease Expense
- - revenue equipment as a percentage of revenue, before fuel surcharge,  was 2.4%
compared to 3.4% for the same period in 2002. These decreases were primarily due
to the increase in purchased  vehicles as a percentage of total  vehicles in our
fleet, as discussed above.

Purchased  transportation  decreased  as a  percentage  of revenue,  before fuel
surcharge,  to 7.8% for the six months  ended June 30,  2003,  from 8.1% for the
same  period in 2002.  For the  three  months  ended  June 30,  2003,  purchased
transportation as a percentage of revenue,  before fuel surcharge,  decreased to
8.0% from  8.3% for the same  period in 2002.  These  decreases  were due to the
increase in revenue per mile. Our independent  contractors provided 10.3% of our
total  fleet at June 30,  2003,  compared  to 10.2% for the same period in 2002.
Independent  contractors  pay their own expenses and are  compensated at a fixed
rate per mile.

Miscellaneous  operating expenses  decreased as a percentage of revenue,  before
fuel  surcharge,  to 2.4% for the six months ended June 30, 2003,  from 2.6% for
the same period in 2002. For the three months ended June 30, 2003, miscellaneous
operating expenses as a percentage of revenue, before fuel surcharge,  decreased
to 2.5% from 2.6% for the same period in 2002.  These  decreases as a percentage
of  revenue  were  attributable  to  higher  revenue  per  tractor,  which  more
efficiently spread these costs over greater revenue.

                                       13

As a result of the above factors, our operating ratio (operating  expenses,  net
of fuel  surcharge,  as a percentage of revenue,  before fuel surcharge) for the
six  months  ended  June 30,  2003,  decreased  to 82.7% from 84.1% for the same
period in 2002.  Our  operating  ratio  decreased  to 81.7% for the three months
ended June 30, 2003, compared to 83.4% for the same period in 2002.

For the six months and three months ended June 30, 2003, net interest expense as
a  percentage  of revenue,  before fuel  surcharge,  remained at less than 0.1%,
consistent with net interest expense levels for the same periods in 2002.

Income  taxes have been  provided  at the  statutory  federal  and state  rates,
adjusted for certain  permanent  differences  between  financial  statement  and
income tax  reporting.  Our effective tax rate declined from 40.7% to 40.0% from
the 2002  periods  to the 2003  periods as a result of  certain  tax  management
techniques.

As a result of the preceding changes, our net income as a percentage of revenue,
before  fuel  surcharge,  was  10.3% for the six  months  ended  June 30,  2003,
compared to 9.4% for the same period in 2002.  For the three  months  ended June
30, 2003,  net income as a percentage  of revenue,  before fuel  surcharge,  was
10.9%, compared to 9.8% for the same period in 2002.

LIQUIDITY AND CAPITAL RESOURCES

The growth of our business has required  significant  investment  in new revenue
equipment.  Our  primary  sources  of  liquidity  have been  funds  provided  by
operations and our line of credit. Net cash provided by operating activities was
approximately  $37.2 million for the first six months of 2003, compared to $28.8
million for the corresponding period in 2002.

Net cash used in investing  activities  totaled  $35.7 million for the first six
months of 2003  compared  to $13.3  million  for the same  period  in 2002.  The
increase  was the result of an  increase  in  delivery  and  payment for revenue
equipment in the 2003 period,  compared to the 2002 period.  The 2002 period was
an unusually low period for us with respect to deliveries of revenue  equipment.
We expect our capital  expenditures,  net of  dispositions,  to be approximately
$20.0 million for the remainder of 2003.

Net  cash  used  in  financing  activities  remained  relatively  consistent  at
approximately  $0.5  million for the first six months of 2003,  compared to $0.7
for the same period in 2002.  Net cash used in financing  activities  during the
first six months of 2003 and 2002 was  primarily  for the  payment of  long-term
debt.

We maintain a line of credit totaling $50.0 million.  We are obligated to comply
with certain financial covenants under our line of credit and were in compliance
with these  covenants  at June 30,  2003.  The rate of  interest  on  borrowings
against the line of credit will vary  depending  upon the interest rate election
made by us, based upon either the London  Interbank  Offered Rate ("Libor") plus
an applicable  margin,  or the prime rate.  Borrowings  under the line of credit
amounted to $12.2 million at June 30, 2003.  The line of credit  expires in June
2004.  The line of  credit  contains  a letter of  credit  subfacility  of $10.0
million that directly reduces available  borrowing.  At June 30, 2003, the total
amount of issued but unused letters of credit was $8.4 million.

Through our  subsidiaries,  we have entered into lease agreements under which we
lease revenue equipment.  The total amount outstanding under these agreements as
of June 30, 2003, was $9.7 million, with $4.9 million due in the next 12 months.

                                       14

As of June 30,  2003,  we held $37.2  million in cash and cash  equivalents.  We
believe we will be able to finance our near term needs for working  capital,  as
well as  acquisitions  of revenue  equipment,  with cash flows from  operations,
borrowings  available  under our line of credit or other sources,  and operating
lease financing believed to be available to finance revenue  equipment.  We will
continue to have significant capital  requirements over the long term, which may
require us to incur debt or seek additional equity capital.  The availability of
this capital will depend upon prevailing market conditions,  the market price of
the common stock and several other  factors over which we have limited  control,
as well as our financial condition and results of operations.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in accordance with accounting principles
generally accepted in the United States of America requires that management make
a number of  assumptions  and  estimates  that  affect the  reported  amounts of
assets,  liabilities,   revenue  and  expenses  in  our  consolidated  financial
statements and accompanying  notes. Our critical  accounting  policies are those
that affect our financial statements  materially and involve a significant level
of judgment by management.  Our critical  accounting  policies  include  revenue
recognition,  insurance  and claims  reserves,  depreciation  and  amortization,
valuation of long-lived  assets and accounting for income taxes.  For additional
information,  please refer to the  discussion  of Critical  Accounting  Policies
contained  in our most  recent  annual  report on Form 10-K under  "Management's
Discussion  and  Analysis of  Financial  Condition  and Results of  Operations -
Critical  Accounting  Policies  and  Estimates"  and  in  the  footnotes  to our
consolidated   financial   statements,   particularly  note  1.  There  were  no
significant  changes in our critical  accounting  policies  during the first six
months of 2003.

FACTORS THAT MAY AFFECT FUTURE RESULTS

Our future  results may be  affected  by a number of factors  over which we have
little or no control. Fuel prices, insurance and claims costs, liability claims,
interest  rates,  the  availability  of qualified  drivers,  fluctuations in the
resale value of revenue  equipment,  economic and customer  business  cycles and
shipping  demands  are  factors  over  which  we  have  little  or  no  control.
Significant  increases or rapid  fluctuations in fuel prices,  interest rates or
insurance costs or liability claims, to the extent not offset by fuel surcharges
and increases in freight rates, and the resale value of revenue equipment, could
reduce our profitability.  Weakness in the general economy, including a weakness
in consumer demand for goods and services,  could adversely affect our customers
and our growth and revenues, if customers reduce their demand for transportation
services.  Weakness in customer  demand for our  services or in the general rate
environment  may also  restrain  our  ability to  increase  rates or obtain fuel
surcharges.  It is also not possible to predict the effects of terrorist attacks
and  subsequent  events on the economy or on customer  confidence  in the United
States, or the impact, if any, on our future results of operations.

BUSINESS  UNCERTAINTIES.  We have  experienced  significant  and rapid growth in
revenue and profits since the inception of our business in 1990. There can be no
assurance  that our business will  continue to grow in a similar  fashion in the
future or that we can  effectively  adapt our  management,  administrative,  and
operational  systems to respond to any future growth.  Further,  there can be no
assurance  that our operating  margins will not be adversely  affected by future
changes in and expansion of our business or by changes in economic conditions.

                                       15

INSURANCE.  Our future  insurance and claims  expenses  might exceed  historical
levels,  which could reduce our earnings.  During 2002, we were self-insured for
personal injury and property damage  liability,  cargo liability,  collision and
comprehensive  up to a maximum  limit of $1.75 million per  occurrence.  We were
self-insured  for workers'  compensation  up to a maximum  limit of $500,000 per
occurrence.  In the  first  quarter  of  2003,  we  amended  our  self-insurance
retention  levels to a combined  $2.0 million for  personal  injury and property
damage  liability,  cargo  liability,  collision,   comprehensive  and  workers'
compensation   per   occurrence.   Our  maximum   self-retention   for  workers'
compensation  where a traffic  accident is not  involved  remains  $500,000  per
occurrence.  We maintain insurance with licensed  insurance  companies above the
amounts for which we self-insure. Following changes made in the first quarter of
2003, our insurance policies now provide for excess personal injury and property
damage  liability  up to a total of $35.0  million per  occurrence,  compared to
$30.0  million  per  occurrence  for  2002,  and  cargo  liability,   collision,
comprehensive and workers'  compensation coverage up to a total of $10.0 million
per  occurrence.  Our personal  injury and property damage policies also include
coverage for punitive damages where such coverage is allowed.

If the number of claims for which we are self-insured  increases,  our operating
results could be adversely  affected.  After several years of aggressive pricing
in the 1990s,  insurance  carriers raised premiums which increased our insurance
and claims  expense.  The terrorist  attacks of September 11, 2001,  exacerbated
already difficult  conditions in the United States insurance market resulting in
additional  increases in our insurance  expenses.  If these expenses continue to
increase,  or if the  severity  or  number  of claims  increase  or  exceed  our
self-retention  limits,  and if we are unable to offset the resulting  increases
with higher  freight  rates,  our earnings  could be  materially  and  adversely
affected.

REVENUE EQUIPMENT. Our growth has been made possible through the addition of new
revenue  equipment.  Difficulty in financing or obtaining new revenue  equipment
(for  example,  delivery  delays from  manufacturers  or the  unavailability  of
independent contractors) could restrict future growth.

In the past we have  acquired new  tractors  and  trailers at favorable  prices,
including  agreements with the  manufacturers to repurchase the tractors from us
at agreed  prices.  Current  developments  in the secondary  tractor and trailer
resale  market have  resulted in a large supply of used tractors and trailers on
the market.  This has  depressed  the market  value of used  equipment to levels
significantly  below  the  prices  at which  the  manufacturers  have  agreed to
repurchase  the  equipment.  Accordingly,  some  manufacturers  may refuse or be
financially unable to keep their commitments to repurchase  equipment  according
to the terms of our agreements with them. Some  manufacturers have significantly
increased new equipment prices,  in part to meet new engine design  requirements
imposed,  effective  October 1, 2002, by the EPA, and have eliminated or sharply
reduced the price of repurchase commitments.

Our business plan takes into account new equipment price increases due to engine
design  requirements  imposed  effective  October  1,  2002,  by  the  EPA,  and
potentially lower equipment  repurchase  prices. If new equipment prices were to
increase more than anticipated,  or if the price of repurchase  commitments were
to decrease or fail to be honored by equipment manufacturers, we may be required
to increase our depreciation  and financing costs,  write down the value of used
equipment, and/or retain some of our equipment longer, with a resulting increase
in  maintenance  expenses.  If our resulting  cost of revenue  equipment were to
increase, and/or prices of used revenue equipment were to decline, our operating
costs could increase,  which could  materially and adversely affect our earnings
and cash flows, if we are unable to obtain  commensurate  rate increases or cost
savings.  Additionally,  the cost of  operating  new  engines is  expected to be
somewhat higher than the cost of operating older engines, due primarily to lower
anticipated fuel efficiency and higher anticipated  maintenance expenses. If our
fuel or maintenance expenses were to increase as a result of our use of the new,
EPA-compliant  engines,  and we are unable to offset  such  increases  with fuel
surcharges or higher freight rates, our results of operations would be adversely
affected.

                                       16

REGIONAL  OPERATIONS.  Currently,  a  significant  portion  of our  business  is
concentrated  in the  Arizona  and  California  markets  and a general  economic
decline or a natural disaster in either of these markets could have a materially
adverse  effect on our growth and  profitability.  If we do not  continue  to be
successful at deriving a more  significant  portion of our revenues from markets
throughout the United States,  our growth and profitability  could be materially
and  adversely  affected by general  economic  declines or natural  disasters in
those markets.

In  addition  to our  headquarters  in  Phoenix,  Arizona,  we have  established
regional  operations in Katy, Texas;  Indianapolis,  Indiana;  Charlotte,  North
Carolina;  Gulfport,  Mississippi;  Salt Lake City, Utah;  Kansas City,  Kansas;
Portland,  Oregon; Memphis,  Tennessee;  and Atlanta,  Georgia in order to serve
markets in these regions.  Additionally,  we  established  operations in Denver,
Colorado,  subsequent to June 30, 2003.  These regional  operations  require the
commitment of additional revenue equipment and personnel,  as well as management
resources, for future development.  Should the growth of our regional operations
throughout  the United  States slow or stagnate,  the results of our  operations
could be adversely affected.  We may encounter operating conditions in these new
markets  that differ  substantially  from those  previously  experienced  in our
western  United  States  markets.  There can be no  assurance  that our regional
operating strategy,  as employed in the western United States, can be duplicated
successfully  in the other  areas of the United  States or that it will not take
longer than expected or require a more  substantial  financial  commitment  than
anticipated.

INFLATION. Many of our operating expenses,  including fuel costs and fuel taxes,
are  sensitive  to the  effects  of  inflation,  which  could  result  in higher
operating  costs.  During 2002 and the first six months of 2003, we  experienced
fluctuations in fuel costs, as a result of conditions in the petroleum industry.
We also have periodically experienced some wage increases for drivers. Increases
in fuel costs and driver  compensation could continue during 2003 and may affect
our  operating  income,  unless  we are able to pass  those  increased  costs to
customers  through  rate  increases  or fuel  surcharges.  We have  initiated an
aggressive  program to obtain rate increases and fuel  surcharges from customers
in order to cover increased costs due to these increases in fuel prices,  driver
compensation  and other expenses and have been successful in  implementing  some
fuel  surcharges.   Competitive  conditions  in  the  transportation   industry,
including lower demand for transportation  services,  could limit our ability to
continue to obtain rate increases or fuel surcharges.

DRIVER  RETENTION.  Difficulty  in attracting  or retaining  qualified  drivers,
including independent contractors,  or a downturn in customer business cycles or
shipping  demands also could have a materially  adverse effect on our growth and
profitability.  If a shortage of drivers  should  occur in the future,  or if we
were unable to continue to attract and contract with independent contractors, we
could be  required  to adjust  our  driver  compensation  package,  which  could
adversely affect our profitability if not offset by a corresponding  increase in
rates.

SEASONALITY.  In the transportation  industry,  results of operations frequently
show a seasonal  pattern.  Seasonal  variations  may result from weather or from
customer's  reduced shipments after the busy winter holiday season. To date, our
revenue  has  not  shown  any  significant  seasonal  pattern.  Because  we have
significant  operations in Arizona,  California  and the western  United States,
winter weather generally has not adversely affected our business.  The continued
expansion  of our  operations  throughout  the United  States could expose us to
greater operating  variances due to seasonal weather in these regions.  Shortage
of energy issues in California  and elsewhere in the Western United States could
result in an adverse effect on our operations and demand for our services should
these shortages  continue or increase.  This risk may exist in the other regions
in which we operate, depending upon availability of energy.

                                       17

TECHNOLOGY.  We utilize  Terion's  trailer-tracking  technology  to assist  with
monitoring  the majority of our  trailers.  Terion has emerged from a Chapter 11
bankruptcy  and a plan of  reorganization  has been  approved by the  Bankruptcy
Court. If Terion ceases operations or abandons that trailer-tracking technology,
we would be required to incur the cost of replacing that  technology or could be
forced to operate  without this  technology,  which could  adversely  affect our
trailer utilization and our ability to assess detention charges.

In addition,  substantially  all of our tractors are equipped  with the Qualcomm
tracking  and  communications  system.  If the  Qualcomm  system were to fail or
experience  significant  disruptions in service,  our tractor  utilization might
suffer,  we may be forced to incur the expense of  implementing  a new satellite
tracking and  communications  system or to operate without this technology,  and
our driver turnover could increase as a result of dissatisfaction with the level
or quality of satellite communications service available in our trucks.

STOCK PRICE VOLATILITY. The market price of our common stock could be subject to
significant  fluctuations in response to certain factors,  such as variations in
our  anticipated or actual results of operations or in the anticipated or actual
results of operations of other companies in the transportation industry, changes
in conditions  affecting the economy generally,  including incidents of military
action or terrorism,  analyst reports,  general trends in the industry, sales of
common stock by insiders,  as well as other  factors  unrelated to our operating
results. Volatility in the market price of our common stock may prevent you from
being able to sell your shares at or above the price you paid for your shares.

INVESTMENTS.   We  have   invested  in  and/or  loaned  to   Concentrek,   Inc.,
("Concentrek")  a  transportation  logistics  company  $2.2 million on a secured
basis. Of this $2.2 million, $1.2 million is personally guaranteed by members of
the Knight family. We own approximately 17% of Concentrek,  and the remainder is
owned  by  members  of  the  Knight  family  and  Concentrek's  management.   If
Concentrek's financial position does not continue to improve, or if it is unable
to raise  additional  capital,  we could be forced to write  down all or part of
this investment.

For other  risks and  uncertainties  that might  affect  our future  operations,
please  review  Part  II of our  Annual  Report  on  Form  10-K -  "MANAGEMENT'S
DISCUSSION  AND ANALYSIS OF  FINANCIAL  CONDITIONS  AND RESULTS OF  OPERATIONS -
FACTORS THAT MAY AFFECT FUTURE RESULTS."

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risk from changes in interest rates on debt and
from changes in commodity prices.  Under Financial  Accounting Reporting Release
Number 48, we are required to disclose  information  concerning market risk with
respect to foreign exchange rates, interest rates, and commodity prices. We have
determined that market risk for interest rates and currency fluctuations are not
material  because of our low level of debt and because  all of our  transactions
are in  Unites  States  dollars.  We have not used  derivative  instruments  for
speculation  or  trading.  We have  elected to make the  disclosures  concerning
commodity  price  risk  using  a  sensitivity   analysis   approach,   based  on
hypothetical changes in commodity prices.

COMMODITY  PRICE RISK.  We are subject to  commodity  price risk with respect to
purchases of fuel. Prices and availability of petroleum  products are subject to
political,  economic and market factors that are generally  outside our control.
Because our operations are dependent upon diesel fuel,  significant increases in
diesel  fuel  costs  could  materially  and  adversely  affect  our  results  of
operations and financial  condition if we are unable to pass increased  costs on
to customers  through rate increases or fuel surcharges.  Historically,  we have
sought  to  recover  a portion  of our  short-term  fuel  price  increases  from
customers through fuel surcharges.  Fuel surcharges that can be collected do not
always offset the increase in the cost of diesel fuel.

                                       18

We are party to three contracts  relating to the price of heating oil on the New
York  Merchantile  Exchange  ("NYMX")  that we entered into in  connection  with
volume  diesel fuel  purchases  between  October 2000 and February  2002. If the
price of heating oil on the NYMX falls below $0.58 per gallon we may be required
to pay the  difference  between  $0.58 and the index  price (1) for 1.0  million
gallons  per month for any  twelve  months  between  April 1, 2003 and March 31,
2005,  and (2) for 750,000  gallons per month for the twelve  months of 2005. At
July 4, 2003,  the price of heating oil on the NYMX was $0.79 for  October  2003
contracts.  For each $0.05 per gallon the price of heating  oil would fall below
$0.58  per  gallon  during  the  relevant  periods,  our  potential  loss on the
contracts would be approximately $1.0 million.  However, our net savings on fuel
costs from lower contracts would be approximately $700,000 after taking the loss
on the contracts into consideration. We have valued these items at fair value in
the accompanying June 30, 2003, condensed consolidated financial statements.

ITEM 4. CONTROLS AND PROCEDURES

As required by Rule 13a-15 under the  Exchange  Act, the Company has carried out
an evaluation of the  effectiveness of the design and operation of the Company's
disclosure  controls and  procedures as of the end of the period covered by this
report.  This  evaluation  was  carried out under the  supervision  and with the
participation of the Company's management, including our Chief Executive Officer
and our Chief Financial Officer. Based upon that evaluation, our Chief Executive
Officer and Chief Financial  Officer  concluded that our controls and procedures
were effective as of the end of the period covered by this report. There were no
changes in the Company's internal control over financial reporting that occurred
during the period covered by this report that have materially affected,  or that
are reasonably likely to materially  affect, the Company's internal control over
financial reporting.

Disclosure  controls and procedures are controls and other  procedures  that are
designed to ensure that  information  required to be disclosed in the  Company's
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 Company  reports filed under the Exchange Act is accumulated and
communicated to management,  including the Company's Chief Executive  Officer as
appropriate, to allow timely decisions regarding disclosures.

The  Company  has   confidence   in  its  internal   controls  and   procedures.
Nevertheless,  the Company's  management,  including the Chief Executive Officer
and Chief Financial  Officer,  does not expect that our disclosure  controls and
procedures  or our  internal  controls  will  prevent all errors or  intentional
fraud. An internal  control  system,  no matter how well conceived and operated,
can provide only reasonable, not absolute, assurance that the objectives of such
internal  controls are met.  Further,  the design of an internal  control system
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 internal  control  systems,  no  evaluation  of controls can
provide  absolute  assurance that all control issues and instances of fraud,  if
any, within the Company have been detected.
