   The  following  summary is  qualified  in its  entirety by the more  detailed
information  and the  Consolidated  Financial  Statements,  including  the notes
thereto, appearing elsewhere in this Prospectus. Unless otherwise indicated, all
information  in  this  Prospectus  assumes  no  exercise  of  the  Underwriters'

                                 THE COMPANY

   Knight  is a short  to  medium-haul,  dry  van  truckload  carrier  providing
regional service primarily in the western United States.  The Company transports
general  commodities,  including  consumer  goods,  packaged  foodstuffs,  paper
products,  beverage  containers,  and  imported and  exported  commodities.  The
Company has  recently  established  operations  near  Houston,  Texas to provide
dedicated  services  to one of its larger  customers  and to  commence  regional
service in Texas and  Louisiana.  The Company has also  initiated  operations in
Indianapolis, Indiana, from which it will provide regional and dedicated service
in the Midwest and on the East Coast.

   The Company's  operating  strategy is to achieve  significant  but controlled
growth by providing high quality services to service-sensitive  customers,  with
the goal of  obtaining  sustained,  predictable  business  that  will  allow the
Company to achieve a high level of  equipment  utilization  and other  operating
efficiencies.  Knight  commenced  operations in July 1990, when Kevin,  Gary and
Keith  Knight  joined  Randy  Knight to  establish  a new  short to  medium-haul
truckload  carrier.  The Knights average more than 20 years of experience in the
truckload  industry.  The Company's  goal is to attain growth and  profitability
through  intensive  management  and the creation of  simplified,  cost effective
operations.

   During the five year period  ended  December  31,  1995,  management  led the
Company to a 43.0% compounded  annual increase in operating  revenue and a 61.2%
compounded  annual  increase in net income.  The Company  intends to continue to
develop its business by servicing existing and new customers in its core markets
in the western  United  States,  while  expanding its  operations  and providing
regional and dedicated  service in Texas and Louisiana as well as in the Midwest
and on the East Coast.

   The Company was  incorporated in Arizona in 1989.  Knight's  headquarters are
located at 5601 West Buckeye Road,  Phoenix,  Arizona  85043,  and its telephone
number is (602) 269-2000.

                                  RISK FACTORS

   In  addition  to the other  information  contained  in this  Prospectus,  the
following factors should be carefully  considered in evaluating an investment in
the Company's Common Stock.

ECONOMIC FACTORS

   Fuel  prices,   insurance  costs,  liability  claims,   interest  rates,  the
availability of qualified  drivers,  fluctuations in the resale value of revenue
equipment  and  customers'  business  cycles and  shipping  demands are economic
factors over which the Company has little or no control.  Significant  increases
or rapid  fluctuations in fuel prices,  interest rates or increases in insurance
costs or  liability  claims,  to the extent not offset by  increases  in freight
rates,  would  reduce  the  Company's  profitability.   Although  the  Company's
independent contractors are responsible for paying for their own equipment, fuel
and other operating costs, significant increases in these costs could cause them
to seek higher compensation from the Company or other employment  opportunities.
Difficulty  in  attracting  or  retaining  qualified  drivers or a  downturn  in
customers'  business  cycles or  shipping  demands  also  could  have a material
adverse  effect on the growth and  profitability  of the Company.  If the resale
value of the Company's revenue  equipment were to decline,  the Company could be
forced to retain some of its  equipment  longer,  with a  resulting  increase in
operating  expenses  for  maintenance  and repairs.  At this time a  significant
portion of the Company's  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 material adverse effect on the growth and  profitability of
the Company.  If the Company is successful in deriving a significant  portion of
its revenues from markets in Texas and Louisiana and the Midwest and on the East
Coast in the near  future,  its growth  and  profitability  could be  materially
adversely  affected by general economic  declines or natural  disasters in those
markets.  See "Management's  Discussion and Analysis of Financial  Condition and
Results  of  Operations."  "--Growth  of  Business;  Expansion  of  Operations";
"Business -- Business Strategy"; "-- Fuel."

COMPETITION

   The Company  competes  primarily  with other  regional  short to  medium-haul
truckload carriers,  logistics  providers,  national carriers and other national
equipment providers.  Railroads and air freight also provide competition, but to
a lesser degree. The Company believes that the principal  competitive factors in
its business are service,  pricing and the  availability  and  configuration  of
equipment  that meets a variety of  customers'  needs.  Recently,  the  trucking
industry, including the short to medium-haul truckload market, has been affected
by the availability of excess revenue equipment, which has had a negative effect
on both equipment  utilization and rates. The entire trucking industry is highly
competitive  and  fragmented.  Competition  for the freight  transported  by the
Company is based on freight  rates,  service,  and  efficiency.  A number of the
Company's competitors have greater financial resources,  own more equipment, and
carry a larger volume of freight than the Company.

AVAILABILITY OF DRIVERS AND INDEPENDENT CONTRACTORS

   The Company  utilizes the services of both employee  drivers and  independent
contractors.  Competition for employee  drivers and  independent  contractors is
intense within the trucking  industry,  and the Company has at times experienced
difficulty   attracting  and  retaining   qualified   drivers  and   independent
contractors,  which has resulted in the temporary  idling of revenue  equipment.
From time to time, there have been industry-wide  shortages of qualified drivers
and independent  contractors and there can be no assurance that the Company will
not be affected by a shortage of qualified drivers or independent contractors in
the future. Prolonged difficulty in attracting or retaining qualified drivers or
independent  contractors  could have a material  adverse effect on the Company's
operations and limit its growth.  See "Business -- Drivers and Other  Employers;
Independent Contractor Program."

DEPENDENCE ON KEY PERSONNEL

   The  Company  is  highly  dependent  on the  services  of Randy  Knight,  its
Chairman;  Kevin P. Knight,  its Chief Executive  Officer;  Gary J. Knight,  its
President; and Keith T. Knight, its Executive Vice President. The loss of one or
more of these  officers  could have a material  adverse  effect on the Company's
operations  and  future   profitability.   The  Company  maintains  and  is  the
beneficiary of a "key man" life insurance policy of $1,000,000 on each of Randy,
Kevin, Gary and Keith Knight. See "Management."

GROWTH OF BUSINESS; EXPANSION OF OPERATIONS

   The Company has  experienced  significant  and rapid  growth in revenues  and
profits since the  inception of its business in 1990.  There can be no assurance
that the Company's business will continue to grow in a similar fashion

                                        5
<PAGE>
in the  future  or that  the  Company  can  effectively  adapt  its  management,
administrative and operational systems to respond to any future growth. Further,
there can be no  assurance  that the  Company's  operating  margins  will not be
adversely  affected by future changes in and expansion of the Company's business
or by changes in economic conditions.

   In  early  1996,  the  Company  commenced  regional  and  dedicated  services
operations  from  facilities  located  near Houston and in  Indianapolis.  These
initiatives represent the first established operations of the Company in markets
outside of its primary  regional  operations in the western United  States.  The
Company's senior  management team has not had extensive  experience  operating a
truckload  carrier in either of the Company's  new markets,  and the Company may
encounter  operating  conditions in these new markets that differ  substantially
from those  previously  experienced in its western United States markets.  There
can be no assurance that the Company's  regional  operating strategy as employed
in the western United States can be duplicated  successfully or that it will not
take longer than  expected or require a more  substantial  financial  commitment
than anticipated in order for the Company to generate positive operating results
in these new markets.  See  "Management's  Discussion  and Analysis of Financial
Condition and Results of Operations" and "Business --Marketing and Customers."

CAPITAL REQUIREMENTS

   The trucking industry is capital intensive.  The Company has depended on debt
financing and the proceeds of its initial public  offering in 1994 to obtain new
revenue  equipment,  to  expand  the size of its fleet  and to  maintain  modern
revenue  equipment.  If the  Company  were  unable in the  future to enter  into
acceptable financing arrangements, raise additional equity, or borrow sufficient
funds, it would be forced to limit its growth and operate its revenue  equipment
for longer periods,  which would likely adversely affect the Company's operating
results.  See "Use of Proceeds"  and  "Management's  Discussion  and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources."

ACQUISITION OF REVENUE EQUIPMENT

   The Company's  strategy for continued  growth is dependent on the acquisition
and  deployment  of  additional  revenue   equipment,   and  the  expansion  and
development of operations  beyond the western  region of the United States.  The
Company has recently  established  operations near Houston to provide  dedicated
services  to one of its larger  customers  and to commence  regional  service in
Texas and Louisiana.  The Company has also recently  initiated  expansion of its
operations by establishing operations in Indianapolis in order to access markets
in the  Midwest  and on the  East  Coast.  These  operations  will  require  the
commitment of additional revenue equipment and personnel,  as well as management
resources,  for future  development.  The Company  currently  has orders for the
purchase of 37 tractors (net of  trade-ins)  and 264 trailers (net of trade-ins)
during the 12-month period  commencing  April 1, 1996. There can be no assurance
that the Company will be able to attract and retain  enough  qualified  employee
drivers or engage a sufficient  number of  independent  contractors  to meet its
growth  targets.  Although  Knight  expects  to take  delivery  of this  revenue
equipment during the course of this 12-month period,  delays in the availability
of  equipment  could  occur  due to a number of  factors  beyond  the  Company's
control,  including work  stoppages at the equipment  supplier and equipment and
supply shortages.  Any delay or interruption in the availability of equipment in
the future could have a material  adverse  effect on the Company.  Finally,  the
Company may be forced to curtail its plans for growth due to the  occurrence  of
certain  changes  in  economic  conditions,  particularly  decreased  demand for
truckload  carrier  services.  See  "Business  --  Business  Strategy;   Revenue
Equipment and Maintenance." 

DEPENDENCE ON CERTAIN CUSTOMERS

   For the year ended  December 31,  1995,  the  Company's 25 largest  customers
represented 53.2% of operating  revenue,  its ten largest customers  represented
32.1% of operating revenue and its five largest  customers  represented 19.4% of
operating  revenue.  Most of the Company's  truckload  carriage  contracts  with
customers  are  cancellable  on 30 days  notice.  The loss of one or more  large
customers  could  have a  material  adverse  effect on the  Company's  operating
results. See "Business -- Marketing and Customers."

FUEL

   Fuel is one of the Company's largest operating expenses,  and the Company has
recently experienced sharp increases in its fuel costs.  Increases in fuel taxes
or fuel  prices,  to the extent not offset by  freight  rate  increases,  or any
interruption in the supply of fuel,  could have a material adverse effect on the
Company's  operating  results.  See  "Management's  Discussion  and  Analysis of
Financial  Condition and Results of  Operations  -- Inflation"  and "Business --
Fuel."

                                        6

REGULATION

   Historically,  the Interstate  Commerce  Commission ("ICC") and various state
agencies regulated  truckload  carriers'  operating rights,  accounting systems,
rates  and  charges,  safety,  mergers  and  acquisitions,   periodic  financial
reporting and other matters. In 1995, the passage of certain federal legislation
preempted state regulation of prices,  rates, and services of motor carriers and
eliminated the ICC.  Several ICC functions were transferred to the Department of
Transportation  ("DOT"),  but  a  lack  of  implementing  regulations  currently
prevents the Company from  assessing the full impact of this action.  Generally,
the trucking industry is subject to regulatory and legislative  changes that can
have a material effect on operations. The Company's motor carrier operations are
also  subject  to  environmental  laws  and  regulations,   including  laws  and
regulations  dealing with underground fuel storage tanks, the  transportation of
hazardous  materials and other  environmental  matters. In the event the Company
should fail to comply with applicable regulations,  the Company could be subject
to substantial fines or penalties and to civil or criminal  liability.  There is
no assurance that compliance with  regulations  promulgated from time to time by
the DOT,  Environmental  Protection  Agency ("EPA") or other  regulatory  bodies
exercising  jurisdiction  over the Company will not require the  expenditure  of
substantial  monies.  Such  expenditures,  if they should occur, could adversely
affect the Company's results of operations. See "Business -- Legal Proceedings."

   The Company's  tractor and trailer fleets are registered in Oklahoma and Utah
and operate primarily in the western United States,  including  California.  The
Company is presently  being audited by the State of  California's  Department of
Motor  Vehicles.  Although  no  assessment  has yet  been  made,  California  is
asserting   that  all  the  Company's   trailers  are  subject  to   apportioned
registration  in  California  and that the Company  owes  California  additional
trailer  registration  fees in  excess of those  amounts  previously  paid.  The
Company  intends to vigorously  contest the position  taken by  California.  The
Company  believes  that the  outcome  of the  California  audit  will not have a
materially  adverse  effect on the  Company's  financial  position or results of
operations. See "Business -- Legal Proceedings." 

SELF-INSURED CLAIMS

   The Company is  self-insured  for personal injury and property damage up to a
maximum limit of $100,000 per  occurrence,  for  collision,  comprehensive,  and
cargo liability up to a combined limit of $25,000 per occurrence, and, in states
in which the Company elects to do so,  workers'  compensation up to $250,000 per
occurrence.  If the Company were to experience  numerous  claims in  significant
amounts for which it is self-insured,  or if significant  increases in insurance
costs  should  occur  which  could not be offset by higher  freight  rates,  the
Company's  results of operations could be adversely  affected.  See "Business --
Safety and Risk Management."

ENVIRONMENTAL HAZARDS

   The  Company's  operations  are  subject  to various  environmental  laws and
regulations dealing with the transportation,  storage,  presence,  use, disposal
and  handling  of  hazardous  materials  and  hazardous  wastes,   discharge  of
stormwater and underground fuel storage tanks. The Company rarely engages in the
transportation  of  hazardous  substances  and  underground  storage  tanks  are
situated only on its recently acquired  Indianapolis  property.  However, if the
Company  should be involved  in a spill or other  accident  involving  hazardous
substances,  or if any such substances were found on the Company's properties in
violation of applicable environmental laws and regulations, the Company could be
responsible for clean-up costs,  property damage, fines or other penalties,  any
one of which could have a material adverse effect on the Company.  See "Business
- -- Safety and Risk Management; Regulation; Properties"

SHARES ELIGIBLE FOR FUTURE SALE

   Sales  of a  substantial  number  of  shares  of the  Common  Stock  or their
availability  for sale in the public market  following this offering may have an
adverse effect on prevailing market prices for the Common Stock.  Following this
offering,  the 1,600,000  shares offered hereby will be freely  tradeable unless
acquired by affiliates of the Company. The Selling Shareholders, either in their
individual  capacities or through certain  related trusts and limited  liability
companies  established  for the  benefit  of  their  respective  families,  will
beneficially own 6,028,900 shares, or 60.9%, of the Company's outstanding Common
Stock,  after giving effect to this offering.  The Selling  Shareholders,  along
with the  Company and its other  officers  and  directors,  have agreed with the
Underwriters not to sell, offer or otherwise  dispose of any of their shares for
180 days from the date of this  Prospectus  without the prior written consent of
Alex. Brown & Sons  Incorporated.  After the 180 day period,  all of such shares
will be eligible  for sale under,  and subject to the  limitations  of, Rule 144
under the  Securities  Act of 1933,  as  amended  (the  "Securities  Act").  See
"Principal and Selling Shareholders" and "Shares Eligible for Future Sale."

LIMITS ON CHANGES IN CONTROL

   The Company's Articles of Incorporation and Bylaws contain certain provisions
that could have the effect of making it more  difficult  for a party to acquire,
or discouraging a party from attempting to acquire,  control of the Company. The
Articles of  Incorporation  authorize  the Board of Directors to issue shares of
preferred stock from time to time in one or more  designated  series or classes.
The Board of Directors, without the approval of the shareholders,  is authorized
to establish voting,  dividend,  redemption,  conversion,  liquidation and other
provisions of a particular series or class of preferred stock. In addition,  the
Articles of  Incorporation  contain  provisions  requiring  the  approval of the
holders of 67% or more of the  Company's  issued and  outstanding  voting stock,
voting as a single class, to sell  substantially  all of the Company's assets or
effect any plan of merger or  consolidation  pursuant to which  shares of common
stock of the  Company  are  converted  into the right to  receive  cash or other
consideration. See "Description of Capital Stock."

                               USE OF PROCEEDS

The net proceeds to the Company from the sale of the 800,000  shares  offered on
behalf of the Company are  estimated to be  approximately  $15.3  million  after
deduction of  underwriting  discounts and  commissions  and  estimated  offering
expenses.  It is expected that  approximately  $10.2 million of the net proceeds
from the  shares  offered  on  behalf of the  Company  will be used to repay its
current  line of credit  indebtedness  incurred  primarily  to  acquire  revenue
equipment, with the balance used to acquire additional revenue equipment and for
general corporate purposes. The indebtedness to be repaid has a current interest
rate equal to the London  Interbank  Offered  Rate  (LIBOR)  plus .75% (having a
weighted  average  rate of 5.9% as of March 31,  1996) and matures in July 1997.
The Company will not receive any  proceeds  from the sale of the Common Stock by
the Selling Shareholders.

                                CAPITALIZATION

   The following  table sets forth the current portion of long-term debt and the
capitalization  of the  Company  as of March 31,  1996 and as  adjusted  to give
effect to the sale of the 800,000  shares of Common Stock offered by the Company
hereby (assuming a public offering price of $20.50 per share) and application of
the  estimated  net  proceeds  to  repay  indebtedness  as set  forth in "Use of
Proceeds."

                               DIVIDEND POLICY

   The Company has never paid cash dividends on its Common Stock. Future payment
of  cash  dividends  will  depend  upon  the  financial  condition,  results  of
operations  and capital  requirements  of the Company,  as well as other factors
deemed  relevant by the Board of Directors.  It is the current  intention of the
Company's  Board of  Directors  to retain  earnings to finance the growth of the
Company's business, rather than to pay cash dividends.

                         PRICE RANGE OF COMMON STOCK

   Following the Company's  initial  public  offering of Common Stock on October
25, 1994,  the  Company's  Common  Stock has been traded on the Nasdaq  National

              MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                     CONDITION AND RESULTS OF OPERATIONS

   Except for the historical  information  contained  herein,  the discussion in
this  Prospectus  contains  forward-looking  statements  that involve  risks and
uncertainties.  The Company's actual results could differ  materially from those
discussed  herein.  Factors that could cause or contribute  to such  differences
include,  but are not limited to, those discussed in the sections entitled "Risk
Factors"  and  "Business",  as well as  those  discussed  in  this  section  and
elsewhere in this Prospectus.

GENERAL

   The  following  discussion  analyzes the  Company's  financial  condition and
results of operations for the three month periods ended March 31, 1995 and 1996,
and for the  three-year  period ended  December 31, 1995,  and should be read in
conjunction  with the  Company's  Consolidated  Financial  Statements  and Notes
thereto contained elsewhere in this Prospectus.  Knight was incorporated in 1989
and commenced  operations in July 1990.  For the five year period ended December
31, 1995,  the Company's  operating  revenue grew at a 43.0%  compounded  annual
rate, while net income increased at a 61.2% compounded annual rate.


   In 1994, the Company initiated an independent contractor program. As of March
31, 1996, the Company had retained 129 independent contractors, who provided the
Company with 131 tractors. As a result of the increase in the use of independent
contractors,  the Company has  experienced  a decrease  in  salaries,  wages and
benefits, fuel and maintenance,  and other expenses as a percentage of operating
revenues  and  a  corresponding  increase  in  purchased   transportation  as  a
percentage of operating revenues. Purchased transportation represents the amount
an independent  contractor is paid to haul freight for the Company on a mutually
agreed to per-mile  basis.  The Company's  decision to focus fleet  expansion on
independent  contractors  was based on such  factors  as the  Company's  reduced
capital  requirements  since  the  independent  contractors  provide  their  own
tractors,  the  lower  turnover  rate  that the  Company  has  experienced  with
independent  contractors,  and the  Company's  success in  attracting  qualified
independent contractors.


RESULTS OF OPERATIONS

   The following table sets forth the percentage  relationships of expense items
to operating revenue for the periods indicated:

THREE MONTHS ENDED MARCH 31, 1996 COMPARED TO THREE MONTHS ENDED MARCH 31, 1995

   Operating  revenue for the three  months  ended March 31, 1996  increased  by
39.2% to $16.6  million  from $11.9  million  over the same period in 1995.  The
increase in operating revenue resulted from expansion of the Company's

                                       11

<PAGE>
customer base and increased volume from existing customers,  and was facilitated
by the continued expansion of the Company's fleet,  including an increase in the
Company's  independent  contractor fleet. The Company's fleet increased by 44.4%
to 491 tractors (including 131 owned by independent contractors) as of March 31,
1996 from 340 tractors  (including 55 owned by  independent  contractors)  as of
March 31,  1995.  Average  Revenue  per mile  declined to $1.24 per mile for the
three  months  ended  March 31,  1996 from $1.29 per mile for the same period in
1995 and  equipment  utilization  declined  to an  average  of 29,815  miles per
tractor  for the three  months  ended  March 31,  1996 from an average of 30,534
miles per tractor  for the same  period in 1995 due to weakness in the  domestic
freight market.  These decreases were offset by revenue increases resulting from
the  growth  of the  Company's  independent  contractor  program  combined  with
additional  revenues generated by the Company's expansion of its operations with
the  commencement of dedicated  service and regional  operations near Houston in
early 1996.

   Salaries,  wages and benefits  decreased as a percentage of operating revenue
to 28.5% for the three  months  ended  March  31,  1996 from  31.3% for the same
period in 1995 primarily as a result of the increase in the ratio of independent
contractors  to Company  drivers.  The Company  records  accruals  for  workers'
compensation  insurance  as a component of its claims  accrual,  and the related
expense is reflected in salaries, wages and benefits expense in its consolidated
statements of income.

   Fuel expense  decreased as a percentage of operating revenue to 10.4% for the
three  months  ended  March  31,  1996 from  11.3% for the same  period in 1995.
Although fuel costs increased  slightly,  the overall decrease resulted from the
growth of the Company's independent contractor program.  Independent contractors
are required to pay their own fuel costs.  Increases in fuel costs,  which began
in the latter part of the first  quarter of 1996,  may  increase  the  Company's
operating expenses in subsequent quarters to the extent such increases cannot be
passed through to customers.

   Operations  and  maintenance  expense  decreased as a percentage of operating
revenue  to 5.0% for the three  months  ended  March 31,  1996 from 7.3% for the
corresponding period in 1995. This change resulted from a substantial decline in
trailer lease costs incurred due to an increase in Company owned trailers during
the period and the  continued  growth in the  Company's  independent  contractor
program.

   Insurance and claims expense  decreased as a percentage of operating  revenue
to 3.7% for the three  months ended March 31, 1996 from 4.8% for the same period
in 1995. This decrease was due to a reduction in insurance  premium costs and an
overall relative lower level of new claims reserves.

   Operating taxes and licenses decreased as a percentage of revenue to 3.6% for
the three  months  ended  March 31,  1996 from 4.0% for the same period in 1995.
This  decrease  resulted  primarily  from growth in the  independent  contractor
program. Independent contractors are required to pay their own mileage taxes.

   For  the  three  month  period  ended  March  31,  1996,   depreciation   and
amortization  expense decreased slightly as a percentage of operating revenue to
10.0% from 10.1% for the  corresponding  period in 1995. This decrease  resulted
from the  continued  growth of the  Company's  independent  contractor  program.
Although  depreciation  and  amortization  expense  decreased as a percentage of
operating revenue, depreciation expense increased due to the Company's expansion
of its trailer fleet during the period.

   Purchased  transportation  increased as a percentage of operating  revenue to
18.5% for the three months ended March 31, 1996 from 8.8% for the same period in
1995.  This  increase  was  due  to the  growth  of  the  Company's  independent
contractor  program from 55 tractors as of March 31, 1995 to 131 as of March 31,
1996.

   Communications  and  miscellaneous  operating  expenses  as a  percentage  of
revenues for the three months ended March 31, 1996 was slightly  higher than the
same period in 1995.

   The  Company's  operating  ratio  (operating  expenses  as  a  percentage  of
operating  revenue) for the three months ended March 31, 1996 increased to 82.9%
from 80.2% for the same period in 1995.  Management believes the increase in the
operating  ratio was mainly due to the  competitive  marketplace  resulting in a
lower revenue per mile and lower tractor utilization.

   For the three month period ended March 31,  1996,  net interest  expense as a
percentage  of  revenue  was  slightly  higher  than  the same  period  in 1995,
resulting  from  increased  borrowings  to finance the  purchase  of  additional
revenue equipment.

   Income  taxes have been  provided at the  statutory  federal and state rates,
adjusted for certain  permanent  differences  between  financial  statement  and
income tax reporting.

                                       12
<PAGE>

   As a  result  of  the  preceding  changes,  the  Company's  net  income  as a
percentage of operating  revenue was 9.6% for the three month period ended March
31, 1996 compared to 10.7% for the same period in 1995.

FISCAL 1995 COMPARED TO FISCAL 1994

   Operating  revenue  increased  by 49.6% to $56.2  million  in 1995 from $37.5
million in 1994. This increase resulted from expansion of the Company's customer
base and increased  volume from  existing  customers  and was  facilitated  by a
substantial  increase in the Company's  tractor and trailer fleet,  including an
increase in the Company's independent  contractor fleet, during 1995 compared to
1994.  The Company's  fleet  increased by 45.5% to 425 tractors  (including  115
owned by  independent  contractors)  as of December 31, 1995,  from 292 tractors
(including 30 owned by independent contractors) as of December 31, 1994. Average
Revenue per mile declined to $1.26 per mile for the year ended December 31, 1995
from  $1.29  per mile  for the same  period  in 1994 and  equipment  utilization
declined  to an average of 120,714  miles per tractor in 1995 from an average of
128,994  miles per  tractor  in 1994 due to  weakness  in the  domestic  freight
market.

   Salaries,  wages and benefits expense  decreased as a percentage of operating
revenue to 29.1% for 1995 from 33.8% for 1994 as a result of the increase in the
ratio of  independent  contractors  to  Company  drivers.  The  Company  records
accruals for workers' compensation as a component of its claims accrual, and the
related  expense is  reflected in  salaries,  wages and benefits  expense in its
consolidated statements of income.

   Fuel expense decreased as a percentage of operating revenue to 10.9% for 1995
from 12.7% in 1994. Though fuel costs per mile in 1995 remained  consistent with
1994 fuel costs per mile,  the decrease  was due to the growth of the  Company's
independent  contractor  program.  Independent  contractors  are required to pay
their own fuel costs.

   Operations  and  maintenance  expense  increased  slightly as a percentage of
operating  revenue to 6.6% for 1995 from 6.2% in 1994. This change resulted from
the Company's need to lease trailers on a short term basis to ensure an adequate
trailer pool. The Company's need for additional trailers resulted from the rapid
growth of its independent contractor program.

   Insurance and claims expense  decreased as a percentage of operating  revenue
to 3.7% for the year ended  December  31,  1995 from 4.9% for the same period in
1994.  This  decrease was due to a reduction in  insurance  premium  costs and a
lower than expected  level of actual claims costs during the period.  The claims
accrual  represents  accruals  for the  estimated  uninsured  portion of pending
claims,  including  the potential  for adverse  development  of known claims and
incurred but not reported claims.

   Operating  taxes and license  expense  decreased as a percentage of operating
revenue to 3.8% in 1995 from 4.9% in 1994. This decrease resulted primarily from
growth  in the  independent  contractor  program.  Independent  contractors  are
required to pay their own mileage taxes.

   Depreciation and  amortization  expense declined as a percentage of operating
revenue  to 9.7% for 1995 from 10.9% for 1994.  This  change  resulted  from the
continued  growth  of the  Company's  independent  contractor  program  and  the
Company's increased use of leased trailers.

   Purchased transportation expense increased to 14.0% in 1995 from 1.8% in 1994
due to an increase in the Company's use of independent  contractor tractors from
30 as of December 31, 1994 to 115 as of December 31, 1995.

   Communications and miscellaneous  operating expenses remained steady, with no
significant change taking place in 1995.

   The  Company's  operating  ratio  (operating  expenses  as  a  percentage  of
operating revenue) for 1995 was 81.1% as compared to 78.4% for 1994.  Management
believes the increase in the operating  ratio was due mainly to the  competitive
marketplace resulting in a lower revenue per mile and lower tractor utilization.

   Net interest  expense  declined as a percentage of operating  revenue to 0.4%
for 1995  from  2.0% for 1994.  This  change  resulted  from a  decrease  in the
Company's  debt.  The  decrease  also  reflects  the  full  year  effect  of the
application of the proceeds from the Company's initial public offering to reduce
the Company's debt.

   Income  taxes have been  provided at the  statutory  federal and state rates,
adjusted for certain permanent differences in income for tax purposes, primarily
resulting from the non-deductible portion of reimbursements to drivers for meals
and other expenses.

                                       13
<PAGE>

   As a  result  of  the  preceding  changes,  the  Company's  net  income  as a
percentage of operating revenue was 10.3% in 1995 as compared to 10.9% in 1994.

FISCAL 1994 COMPARED TO FISCAL 1993

   Operating  revenue  increased  by 42.3% to $37.5  million  in 1994 from $26.4
million in 1993. This increase resulted from expansion of the Company's customer
base and increased volume from existing customers.  The increase was facilitated
by a substantial increase in the Company's tractor and trailer fleet during 1994
compared to 1993. Operating revenue during 1994 was enhanced by improved tractor
utilization  resulting  from a reduction of the  Company's  empty mile factor to
10.1% from 11.8%. This improvement contributed to an increase in average revenue
per mile to $1.29 in 1994 from $1.22 in 1993.

   Salaries,  wages and benefits expense  decreased as a percentage of operating
revenue  to 33.8% for 1994 from 35.9% for 1993 as a result of  increased  driver
productivity, relatively fixed general and administrative salary costs per mile,
higher  revenue  per  mile,  and the  initiation  and  growth  of the  Company's
independent contractor program.

   Fuel expense decreased as a percentage of operating revenue to 12.7% for 1994
from 14.3% in 1993 due to the addition of newer,  more fuel  efficient  tractors
and the initiation and growth of the Company's independent contractor program.

   Operations  and  maintenance  expense  increased  slightly as a percentage of
operating  revenue to 6.2% for 1994 from 5.8% in 1993. This change resulted from
additional  maintenance  costs associated with an increase in the average age of
the Company's trailer fleet.

   Insurance and claims expense remained approximately 4.9% of operating revenue
for 1994 and 1993. During this period, the Company experienced relatively stable
insurance costs and claims expense.

   Operating  taxes and license  expense  increased as a percentage of operating
revenue to 4.9% in 1994 from 4.2% in 1993.  This  increase was due to more miles
operated in higher tax rate states.

   Depreciation and  amortization  expense declined as a percentage of operating
revenue  to 10.9% for 1994 from  11.6% for 1993.  The  change  resulted  from an
increase in the Company's revenue per mile and the initiation and development of
the Company's independent contractor program.

   Purchased  transportation expense increased from zero in 1993 to 1.8% in 1994
due to the  implementation of the Company's  independent  contractor  program in
1994.

   Miscellaneous  operating expenses (primarily  administrative costs) decreased
as a  percentage  of operating  revenue to 2.7% in 1994 from 3.4% in 1993.  This
change  resulted from  effective  cost  containment  programs and an increase in
revenue per mile.

   As a result of the changes described above, the Company's operating ratio for
1994 improved to 78.4% from 80.6% for 1993.

   Net interest  expense  declined as a percentage of operating  revenue to 2.0%
for  1994  from  3.2%  for  1993,   despite  the  Company's   increased  capital
requirements,  as a result  of a decline  in  effective  interest  rates and the
application of the proceeds from the Company's initial public offering to reduce
the Company's debt.

   Income  taxes have been  provided at the  statutory  federal and state rates,
adjusted for certain permanent differences in income for tax purposes, primarily
resulting from the non-deductible portion of reimbursements to drivers for meals
and other expenses.

   As a  result  of  the  preceding  changes,  the  Company's  net  income  as a
percentage of operating revenue increased to 10.9% in 1994 from 9.3% in 1993.

LIQUIDITY AND CAPITAL RESOURCES


   The growth of the Company's business has required a significant investment in
new revenue  equipment.  The Company's  primary  sources of liquidity  have been
funds  provided  by  operations,  its  initial  public  offering  in 1994,  term
borrowings to finance equipment purchases, and the Company's line of credit. Net
cash provided by operating  activities  totaled  approximately  $3.5 million and
$1.2  million for the first  three  months of 1996 and 1995,  respectively,  and
$10.7  million,  $10.1 million and $5.5 million for the years ended December 31,
1995, 1994 and 1993, respectively. 

                                       14
<PAGE>
   Capital expenditures for the purchase of revenue equipment,  office equipment
and leasehold  improvements  totaled $9.0 million and $3.0 million for the first
three months of 1996 and 1995, respectively, and $13.4 million, $8.2 million and
$9.5 million for the years ended December 31, 1995, 1994 and 1993, respectively.
The Company anticipates that capital expenditures for the acquisition of revenue
equipment to expand the Company's fleet, net of trade-ins, will be approximately
$8.0 million for the last nine months of 1996.

   Net cash used in financing  activities and net direct equipment financing was
$300,000  for the first three  months of 1996 and 1995 and $700,000 and $800,000
for the years ended  December  31, 1995 and 1994,  respectively.  These  amounts
remain  relatively  low due to the Company's  ability to finance the majority of
its revenue  equipment  purchases  from  operations  and, in 1994, the Company's
application of the net proceeds of its initial public  offering to repay certain
indebtedness. Net cash provided by financing activities and net direct equipment
financing was $2.5 million for the year ended  December 31, 1993.  The Company's
financing  activities  were  primarily  the result of  increasing  debt,  net of
repayments, and reductions from trade-ins to finance the growth of the Company's
tractor and trailer fleet.

   The Company  has a $15  million  line of credit from its lender and uses that
line to  finance  the  acquisition  of  revenue  equipment  and other  corporate
purposes to the extent the cost of such  acquisitions  are not provided by funds
from operations. Under the Company's line of credit, the Company is obligated to
comply with  certain  financial  covenants.  The rate of interest on  borrowings
against the line of credit will vary  depending  upon the interest rate election
made by the Company,  based on either the London Interbank Offered Rate (LIBOR),
the prime rate, or the lender's  certificate  of deposit rate. At March 31, 1996
and June 12, 1996, the Company had borrowings under the revolving line of credit
totaling $5.0 million and $10.2 million, respectively. As of March 31, 1996, the
Company was in technical default of certain financial covenants under one of its
credit facilities. The lender has waived those defaults.

   Management  believes  that the net proceeds of this  offering,  together with
cash flow from operating activities and available borrowings, will be sufficient
to meet the Company's capital needs through the next 18 months. The Company will
continue to have significant capital  requirements over the long term, which may
require  the  Company to incur  debt or seek  additional  equity  capital in the
future.  The  availability  of this capital will depend upon  prevailing  market
conditions,  the market price of the Common  Stock and other  factors over which
the Company has no control,  as well as the  Company's  financial  condition and
results of operations.

SEASONALITY


   To date,  the  Company's  revenue  has not  shown  any  significant  seasonal
pattern.  Because the Company has operated primarily in Arizona,  California and
the western United States,  winter weather generally has not adversely  affected
the Company's  business.  Expansion of the Company's  operations  into Texas and
Louisiana,  as well as in the Midwest and on the East  Coast,  could  expose the
Company to greater operating variances due to seasonal weather conditions. 

INFLATION


   Many of the  Company's  operating  expenses,  including  fuel  costs and fuel
taxes,  are sensitive to the effects of inflation,  which could result in higher
operating costs.  The effects of inflation on the Company's  business during the
first three months of 1996 and the years ended December 31, 1995,  1994 and 1993
generally were not significant. See "Business -- Fuel."

                              INDUSTRY OVERVIEW


   The Company operates in the non-local segment of the trucking industry, which
segment had estimated  revenues of $330 billion in 1995.  The trucking  industry
can be further  segmented  into an  estimated  $55  billion  for-hire  truckload
segment and an estimated $110 billion private fleet segment,  in which companies
transport goods for their own account.  Truckload carriers  typically  transport
full  trailer  loads  directly  from  origin  to  destination  without  en route
handling.

   The truckload  industry is highly  fragmented,  with the ten largest for-hire
truckload  carriers  accounting  for less than 18% of total  for-hire  truckload
revenues  in 1995.  A variety of niches  have  developed  within  the  truckload
industry  based  upon  equipment  type,  length of haul,  geographic  region and
service criteria. The truckload  transportation industry currently is undergoing
changes that affect both shippers and carriers. An increasing number of shippers
are  focusing  their  capital  resources  on their  primary  businesses  and are
outsourcing   their   transportation   requirements  to  independent   carriers.
Furthermore,  many  shippers are seeking to reduce the time and cost of bringing
finished  products  to the  market  quickly  through  the  use  of  just-in-time
inventory  management and regional  assembly/distribution  methods, all of which
make  on-time  pickup and  delivery  requirements  more  important  to shippers.
Shippers also are seeking to reduce the number of  authorized  carriers they use
and to establish  service-based,  long-term  relationships with a small group of
preferred  or "core  carriers."  This helps to ensure  higher  quality  and more
consistent service for the shipper,  while providing the carrier the opportunity
for higher equipment  utilization and more predictable  revenue streams. In this
environment,  shippers  selectively  choose carriers that are financially stable
and, based on measurable  attributes,  can meet their  distribution  and service
requirements. For example, carriers must deliver shipments on a timely basis and
possess reliable, quality equipment and offer specialized services to customers.
This  trend  toward  the  use  of  "core  carriers"  offers  significant  growth
opportunities for carriers that possess financial stability and critical mass to
support  high  equipment  utilization,  a  commitment  to  quality  service  and
technological  capabilities.  Carriers that do not possess these capabilities or
that are less  efficient  have  begun to exit  the  truckload  industry  through
liquidation or from continued industry consolidation.  The Company believes that
this consolidation trend in the industry will continue and that the trend toward
consolidation  will  provide  growth  opportunities  for  efficient,   well  run
carriers. 

   Many carriers have focused on regional growth strategies,  as over 66% of the
truckload market is in shorter length (less than 500 miles) markets.  A regional
focus  provides  a  carrier  the  opportunity  to  haul  loads  from  origin  to
destination,  without  any need for  intermediate  sorting,  and  increases  the
opportunities for providing higher service levels to customers.  Furthermore,  a
shortage of qualified drivers  continues to constrain the truckload market,  and
truckload  carriers are constantly  seeking  methods,  such as increased  driver
compensation and other techniques,  to attract and retain drivers. Carriers with
a regional focus participating in the short to medium-haul market generally have
had more success in attracting and retaining  drivers because drivers may return
home with more regularity.

                                   BUSINESS

   Except for the historical  information  contained  herein,  the discussion in
this  Prospectus  contains  forward-looking  statements  that involve  risks and
uncertainties.  The Company's actual results could differ  materially from those
discussed  herein.   Factors  that  could  cause  or  contribute  to  such  such

entitled "Risk Factors" and  "Management's  Discussion and Analysis of Financial
Condition and Results of Operations," as well as those discussed in this section
and elsewhere in this Prospectus.

OVERVIEW

   Knight  is a short  to  medium-haul,  dry  van  truckload  carrier  providing
regional service primarily in the western United States.  The Company transports
general  commodities,  including  consumer  goods,  packaged  foodstuffs,  paper
products,  beverage  containers,  and  imported and  exported  commodities.  The
Company has recently  established  operations near Houston to provide  dedicated
services  to one of its larger  customers  and to commence  regional  service in
Texas and Louisiana.  The Company has also initiated  operations in Indianapolis
from which it will provide regional and dedicated  service in the Midwest and on
the East Coast. 

   The Company's  operating  strategy is to achieve  significant  but controlled
growth by providing high quality services to service-sensitive  customers,  with
the goal of  obtaining  sustained,  predictable  business  that  will  allow the
Company to achieve a high level of  equipment  utilization  and other  operating
efficiencies.  Knight  commenced  operations in July 1990, when Kevin,  Gary and
Keith  Knight  joined  Randy  Knight to  establish  a new  short to  medium-haul
truckload  carrier.  The Knights average more than 20 years of experience in the
truckload  industry.  The Company's  goal is to attain growth and  profitability
through  intensive  management  and the creation of  simplified,  cost effective
operations.

   During the five year period  ended  December  31,  1995,  management  led the
Company to a 43.0% compounded  annual increase in operating  revenue and a 61.2%
compounded  annual  increase in net income.  The Company  intends to continue to
develop its business by servicing existing and new customers in its core markets
in the western  United  States,  while  expanding its  operations  and providing
regional and  dedicated  service in Texas and Lousiana as well as in the Midwest
and on the East Coast.

BUSINESS STRATEGY

   Knight's  business  strategy focuses on four key elements:  growth,  regional
operations, service and operating efficiencies.

   o  Growth.  Knight's  objective is to achieve  significant growth through the
      controlled expansion of high quality service to existing customers and the
      development of new customers in its expanded market areas. The Company has
      achieved  substantial  revenue growth in the western United States, with a
      particular emphasis on the Arizona and California markets. The Company has
      developed  an  independent  contractor  program in order to  increase  its
      tractor fleet,  while minimizing  capital  investment by the Company,  and
      provide additional  service to customers.  The Company believes that there
      are significant  opportunities to continue to increase its business in the
      short to medium-haul market by pursuing existing  strategies and expanding
      its dedicated services.


   o  Regional  Operations.  As part of its regional  operations focus, in early
      1996, the Company established operations near Houston to meet the needs of
      one of its larger customers and to commence  regional service in Texas and
      Louisiana.  During the same period, the Company also initiated  operations
      in  Indianapolis  in order to expand the  Company's  customer  base in the
      short to medium-haul  market and provide regional and dedicated service to
      customers in the Midwest and on the East Coast.


   o  Service. Knight's operating strategy is to provide a high level of service
      to customers,  establishing  the Company as a preferred or "core  carrier"
      for  shippers  who  have  time  sensitive,  high  volume  or  high  weight
      requirements.   The  Company's  services  include  multiple  pick-ups  and
      deliveries,  dedicated  equipment and  personnel,  pick-ups and deliveries
      within  narrow time  frames,  specialized  training of drivers,  and other
      services  tailored to  customers'  needs.  The Company  has  developed  an
      independent  contractor  program  to  increase  the  size  of its  revenue
      equipment  fleet and,  thus,  provide  better  service to  customers.  The
      Company has adopted an equipment  configuration  that meets a wide variety
      of customer  needs and  facilitates  customer  shipping  flexibility.  The
      Company  uses  lightweight  tractors  and high cube  trailers  capable  of
      handling both high volume and high weight shipments.

                                       17
<PAGE>

   o  Operating Efficiencies. The Company employs a number of strategies that it
      believes are instrumental to its efforts to achieve and maintain operating
      efficiencies. Knight seeks to maintain a simplified operation that focuses
      on operating dry vans in  particular  geographical  and shipping  markets.
      This approach allows the Company to concentrate  its marketing  efforts to
      achieve  higher  penetration of its targeted  service  areas.  The Company
      seeks operating economies by purchasing a generally uniform and compatible
      fleet of tractors and trailers that facilitates  Knight's ability to serve
      a  broad  range  of  customer  needs  and  thereby   maximizes   equipment
      utilization  and  efficiencies in equipment  maintenance and  positioning.
      Knight  intends  to  maintain  its new and  efficient  equipment  fleet by
      following  a regimen  of  tractor  replacement  on a three  year cycle and
      trailer replacement on a five to seven year cycle.

CUSTOMER SERVICE

   Knight  believes  that its principal  competitive  strength is its ability to
provide consistent, timely, flexible and cost effective service to shippers. The
Company's  strategy  is to  develop  and  service  specified  traffic  lanes for
customers  who ship on a  consistent  basis,  thereby  providing  a  predictable
traffic flow and ensuring high equipment  utilization.  The short to medium-haul
segment of the truckload  carrier market demands timely pickup and delivery and,
in some cases,  response on short  notice of  equipment  availability.  Although
price is a  primary  concern  to all  shippers,  the  Company  seeks to obtain a
competitive  advantage by  providing  high quality  service.  Knight's  services
include  multiple  pickups and  deliveries,  dedicated  equipment and personnel,
on-time  pickup and  delivery  within  narrow time  frames,  specialized  driver
training and other services  tailored to customers'  needs.  To be responsive to
customers' and drivers' needs, the Company often assigns  particular drivers and
equipment to prescribed  routes,  providing  better service to customers,  while
obtaining higher equipment utilization.

   Knight targets a trailer/tractor  ratio of 2.7 to 1. Management believes this
ratio  promotes  efficiency and allows it to serve a large variety of customers'
needs,  without  significantly  changing  or  modifying  equipment.  The Company
operates a uniform  fleet of 53 foot long,  102 inch wide,  high cube  trailers,
including 45  refrigerated  trailers in its dedicated  fleet as of June 1, 1996.
The efficiency and flexibility provided by its fleet  configurations  permit the
Company to handle  both high volume and high weight  shipments.  Knight's  fleet
configuration  also  allows  the  Company to move  freight on a  "drop-and-hook"
basis, increasing asset utilization and providing better service to customers.

DRIVERS AND OTHER EMPLOYEES

   The recruitment,  training and retention of qualified drivers is essential to
support the Company's  continued growth and to meet the service  requirements of
the  Company's  customers.  Drivers are  selected in  accordance  with  specific
Company  quality  guidelines  relating  primarily  to  safety  history,  driving
experience,  road test  evaluations  and other personal  evaluations,  including
physical examinations and mandatory drug and alcohol testing. Once selected, the
Company's  drivers are  referred to as "driving  associates"  to  emphasize  the
driver's important role within the Company. Drivers are trained in all phases of
the Company's policies and procedures,  including customer service requirements,
general operations,  fuel conservation and equipment maintenance,  operation and
safety.

   The  Company  seeks  to  maintain  a  qualified  driver  force  by  providing
attractive  and  comfortable   equipment,   direct   communication  with  senior
management,  competitive  wages and  benefits and other  incentives  designed to
encourage driver retention and long-term  employment.  Many drivers are assigned
to  dedicated  or  semi-dedicated   fleet  operations,   thereby  enhancing  job
predictability.  Drivers  are  recognized  for  providing  superior  service and
developing  good safety records and must  successfully  complete  driver reviews
administered by the Company's human resources department.

   Knight's  drivers are  compensated on the basis of miles driven and length of
haul. Drivers also are compensated for additional  flexible services provided to
the Company's  customers.  Drivers participate in Knight's 401(k) program and in
Company-sponsored  health, life and dental plans. The Company has also adopted a
stock option program in which drivers who meet certain  criteria are eligible to
participate.  See  "Executive  Compensation  and Other  Information--1994  Stock
Option Plan; 401(k) Plan."

   As of March 31, 1996, Knight employed 522 persons; of these 399 were drivers,
30  were  in  maintenance,  11  were  in  sales  and  marketing,  and 82 were in
administration  and  management.  The  Company  also  had  contracted  with  129
independent  contractors as of March 31, 1996 to provide  tractors.  None of the
Company's employees is represented by a labor union.

                                       18
<PAGE>

INDEPENDENT CONTRACTOR PROGRAM

   The Company initiated and began to develop an independent  contractor program
during 1994. Because  independent  contractors  provide their own tractors,  the
independent  contractor  program  provides the Company an alternative  method of
obtaining  additional  revenue  equipment.  The  Company  intends to continue to
increase its use of independent  contractors.  As of March 31, 1996, the Company
had 129  independent  contractors  who owned and  operated  131  tractors.  Each
independent contractor enters into a contract with the Company pursuant to which
it is required to furnish a tractor and a driver exclusively to transport,  load
and unload goods  carried by the  Company.  Independent  contractors  are paid a
fixed  level of  compensation  based  on  total  trip-loaded  and  empty  miles.
Independent  contractors  are obligated to maintain  their own equipment and pay
for  their  own  fuel.  The  Company  provides  trailers  for  each  independent
contractor.  The Company also provides  maintenance services for its independent
contractor tractors for a charge.

MARKETING AND CUSTOMERS

   Knight  provides   carrier   service  to   manufacturers,   retailers,   food
distributors,  agricultural  producers,  and  other  uses  of dry  van  service.
Knight's  location in Phoenix allows it to serve the western United States.  The
Company's  operations  near  Houston  allow it to serve the Texas and  Louisiana
region. Similarly, Knight's operations in Indianapolis allow it to serve markets
in the Midwest and on the East Coast. From these same locations,  Knight is able
to meet particular customer needs by providing dedicated services. The Company's
standard  dedicated fleet services involve management of a significant part of a
customer's  transportation  operations.   Under  a  dedicated  carriage  service
agreement, the Company provides drivers, equipment and maintenance, and, in some
instances,  transportation  management  services  that  supplement  the in-house
transportation  department.  The Company's  primary  arrangements  for dedicated
services in Houston  obligate the Company to provide a portion of its customer's
transportation  needs  from  one of the  customer's  distribution  centers.  The
Company provides these services through Company  furnished revenue equipment and
drivers.

   The Company's sales and marketing  function is led by its senior  management,
who are assisted by other sales  professionals.  The  Company's  marketing  team
emphasizes  the  Company's  high level of service and ability to  accommodate  a
variety of customer needs. The Company's  marketing efforts are designed to take
advantage  of  the  trend  among  shippers  toward  private  fleet  conversions,
outsourcing  transportation  requirements,  and the use of core carriers to meet
shippers' needs.

   For the year ended  December 31,  1995,  the  Company's 25 largest  customers
represented 53.2% of operating revenue.  The Company believes that a substantial
majority of the Company's 25 largest  customers  regard Knight as a preferred or
"core"  carrier.   Most  of  the  Company's  truckload  carriage  contracts  are
cancellable  on 30 days notice.  The loss of one or more large  customers  could
have a material adverse effect on the Company's operating results.

REVENUE EQUIPMENT AND MAINTENANCE

   A  substantial  majority of the  Company's  equipment  fleet is  standardized
equipment  manufactured to its  specifications.  The Company operates a standard
fleet of 53 foot long, 102 inch wide, high cube trailers,  and, in its dedicated
fleet,  approximately  45 refrigerated  trailers.  The Company believes that its
equipment  acquisition  program  allows it to meet the needs of a wide  range of
customers in the dry van truckload  market while, at the same time,  controlling
costs  relating to  maintenance,  driver  training and  operations.  The Company
considers a number of factors in deciding which equipment to purchase, including
economy,  price,  technology,  warranty terms,  manufacturers'  support,  safety
features, driver comfort and resale value. To reduce the Company's risk on trade
or resale, the Company has negotiated  conditional  repurchase  commitments with
the manufacturers to allow the Company, at its option, to trade back tractors to
the manufacturer at an agreed price, subject to certain conditions. To date, the
Company has not elected to exercise its rights under these agreements because it
has been able to negotiate more favorable trade-in terms. At March 31, 1996, the
Company operated 360 Company-owned tractors with an average age of 1.4 years and
1,264 trailers with an average age of 2.1 years.  The following  table shows the
number of units and age of revenue  equipment  operated  by the Company at March
31, 1996:

                                   ========== ==========

   The  Company  seeks to  minimize  the  operating  costs of its  tractors  and
trailers  by   maintaining  a  relatively   new  fleet   featuring  cost  saving
technologies.  The Company's  current  policy is to replace most of its tractors
within  36  months  after  the date of  purchase.  The  Company's  strategy  for
replacing its tractors is based on various factors, including the used equipment
market,  technological  improvements,  fuel  efficiency and prevailing  interest
rates. The Company's  current policy is to replace its trailer fleet over a five
to  seven  year  period.  Actual  replacement  depends  upon  the  condition  of
particular equipment,  its resale value and other factors. The Company employs a
strict preventive  maintenance program designed to minimize equipment down time,
facilitate customer service, and enhance trade value when equipment is replaced.

   The  Company  operates  primarily  Freightliner  tractors,  most of which are
powered  by  electronically  controlled  diesel  engines.  These  electronically
controlled  engines  decrease fuel  consumption and control speed.  All tractors
have air-ride  suspension  systems and other modern features designed to enhance
performance  and provide driver  comfort.  As of March 31, 1996, the Company had
ordered 37 new tractors  (net of trades),  and 264 new trailers  (net of trades)
intended for use  primarily by  independent  contractors,  for delivery over the
12-month period beginning April 1, 1996.

OPERATIONS

   The Company's  headquarters are located in Phoenix,  where the administrative
offices,  truck terminal,  and dispatching and maintenance  services relating to
Knight's  Western  region  operations  are located.  In early 1996,  the Company
established  regional  operations in Indianapolis and near Houston.  Each of the
Company's regional operations  includes  dispatchers and other support personnel
who are assigned a specific geographic area. Dispatchers work closely with sales
and marketing  personnel and drivers to enhance equipment  utilization and serve
as the contact,  on a daily basis,  with  customers  and shipping and  receiving
personnel.

   Knight uses an IBM AS/400  computer  driven by  Innovative  Software  and the
Octel  Voice   Communication   Systems  to  monitor   pick-ups  and  deliveries,
communicate with drivers and enhance overall control of Company operations. Each
of the Company's regional  operations centers is linked to the Company's Phoenix
headquarters by the IBM AS/400 computer system. The Company provides  electronic
data  interchange  ("EDI")  services to shippers  requiring  such  service.  The
capabilities  of these  systems  enhance the Company's  operating  efficiency by
providing cost effective access to detailed information concerning equipment and
shipment status and specific customer requirements,  and also permit the Company
to respond promptly and accurately to customer requests. The system also assists
the Company in matching available equipment and loads.

SAFETY AND RISK MANAGEMENT

   The Company is committed to ensuring that it has safe drivers and independent
contractors.  The Company regularly  communicates with drivers to promote safety
and to  instill  safe  work  habits  through  Company  media and  safety  review
sessions.  These programs reinforce the importance of driving safety, abiding by
all laws and regulations  regarding such matters as speed and driving hours, and
performing equipment inspections. The Company conducts quarterly safety training
meetings for its drivers and independent  contractors.  In addition, the Company
has an innovative recognition program for driver safety performance.

   The Company's Safety Director reviews all accidents, takes appropriate action
related to drivers,  examines  trends and  implements  changes in  procedures or
communications  to address any safety  issues.  Management's  emphasis on safety
also is  demonstrated  through  its  equipment  specifications  and  maintenance
programs.

                                       20
<PAGE>
   The  Company  requires  prospective  drivers  to  meet  higher  qualification
standards than those required by the DOT. The DOT requires the Company's drivers
and independent  contractors to obtain  national  commercial  driver's  licenses
pursuant to  regulations  promulgated by the DOT. The DOT also requires that the
Company implement a drug testing program in accordance with DOT regulations. The
Company's program includes pre-employment, random, post-accident and post-injury
drug testing.

   The primary  claims arising in the Company's  business  consist of cargo loss
and damage,  workers'  compensation,  and auto  liability  (personal  injury and
property  damage).  The Company is self-insured for personal injury and property
damage  up to a  maximum  limit  of  $100,000  per  occurrence,  for  collision,
comprehensive  and  cargo  liability  up to a  combined  limit  of  $25,000  per
occurrence,  and, in states in which the Company  elects to do so, for  workers'
compensation up to $250,000 per occurrence.  The Company maintains  insurance to
cover liabilities in excess of these amounts.  The Company's  insurance policies
provide  for  general  liability  coverage  up  to  $2,000,000  per  occurrence,
automobile  liability coverage up to $1,000,000 per occurrence,  cargo insurance
coverage up to $2,500,000  per  occurrence  and  additional  umbrella  liability
coverage  up to  $14,000,000.  The  Company  also  maintains  primary and excess
coverage  for  employee  medical  expenses  and  hospitalization,  and damage to
physical  properties.  The Company  carefully  monitors claims and  participates
actively  in  claims  estimate  and  adjustment.  The  estimated  costs  of such
self-insured  claims,  which  include  estimates  for  incurred but not reported
claims, are accrued as liabilities on the Company's balance sheet.

REGULATION

   Historically,  the Interstate  Commerce  Commission ("ICC") and various state
agencies regulated  truckload  carriers'  operating rights,  accounting systems,
rates  and  charges,  safety,  mergers  and  acquisitions,   periodic  financial
reporting  and other  matters.  In 1995,  the  passage  of  federal  legislation
preempted state regulation of prices,  rates, and services of motor carriers and
eliminated the ICC.  Several ICC functions were transferred to the Department of
Transportation  ("DOT"),  but  a  lack  of  implementing  regulations  currently
prevents the Company from  assessing the full impact of this action.  Generally,
the trucking industry is subject to regulatory and legislative  changes that can
have a material effect on operations.

   Interstate  motor  carrier  operations  are  subject  to safety  requirements
prescribed  by the DOT Such matters as weight and  dimensions  of equipment  are
also subject to federal and state  regulation.  In 1988, the DOT began requiring
national commercial driver's licenses for interstate truck drivers.

   The Company's motor carrier operations are also subject to environmental laws
and  regulations,  including laws and regulations  dealing with underground fuel
storage tanks, the transportation of hazardous materials and other environmental
matters.  The Company  has  initiated  programs  to comply  with all  applicable
environmental  regulations.  As part of its safety and risk management  program,
the Company periodically performs an internal environmental review to assist the
Company  achieve  environmental  compliance  and avoid  environmental  risk. The
Company's Phoenix facility was designed,  after  consultation with environmental
advisors,  to contain and properly dispose of hazardous substances and petroleum
products used in connection with the Company's business.  The Company has rarely
transported  environmentally  hazardous substances and, to date, has experienced
no claims for hazardous  substance  shipments.  In the event the Company  should
fail to comply with  applicable  regulations,  the  Company  could be subject to
substantial fines or penalties and to civil or criminal liability.

   The State of  Arizona  has  enacted  laws that  provide  for a water  quality
assurance revolving fund ("WQARF"). The purpose of these laws is to identify and
remediate  areas of  groundwater  contamination  resulting  from the  release of
hazardous substances.  Once an area of contamination is identified,  the Arizona
Department of  Environmental  Quality  ("ADEQ")  designates  the area as a WQARF
Study Area in order to  determine  the extent of  contamination  and to identify
potentially responsible parties.  Responsible parties are liable for the cost of
remediating  contamination.  In December 1987,  ADEQ designated a 25 square mile
area in West Phoenix,  which includes the Company's Phoenix location, as a WQARF
Study  Area.  To date,  ADEQ has not  identified  the  Company as a  potentially
responsible  party or the Company's  facility as a facility  warranting  further
investigation with respect to the WQARF Study Area. The Company has been located
at its  present  Phoenix  facility  since  1990.  Neither  the  Company  nor its
predecessors  have  maintained   underground  petroleum  storage  tanks  at  the
Company's Phoenix location. Prior to 1974, the property upon which the Company's
Phoenix facilities are located was farm land.

   There are two  underground  storage tanks  located on the Company's  recently
acquired Indianapolis  property.  The tanks are subject to regulation under both
federal and state law and are currently being leased to and operated by an

                                       21

independent, third party fuel distributor. The Company assumed the lease as part
of its purchase of the  property.  The lessee has agreed to carry  environmental
impairment  liability  insurance,  naming the Company, as lessor, as an insured,
covering the spillage,  seepage or other loss of petroleum  products,  hazardous
wastes,  or  similar  materials  onto the  leased  premises  and has  agreed  to
indemnify  the Company,  as lessor,  against  damage from such  occurences.  The
Indianapolis  property is located  approximately 0.1 mile east of Reilly Tar and
Chemical Corporation ("Reilly"), a federal superfund site listed on the National
Priorities  List. The Reilly site has known soil and groundwater  contamination.
There are also other sites in the general vicinity of the Company's Indianapolis
property that have known  contamination.  Environmental  reports obtained by the
Company have disclosed no evidence that activities on the Company's Indianapolis
property have caused or contributed to the area contamination.

   The  Company is  currently  engaged in  negotiations  to  purchase a 6.5 acre
parcel of vacant land  adjacent  to its  Indianapolis  facility.  The Company is
still conducting due diligence  concerning the  environmental  condition of this
property.

   The Company  believes it is currently in material  compliance with applicable
laws and regulations and that the cost of compliance has not materially affected
results of operations.  See "-- Legal  Proceedings"  for additional  information
regarding certain regulatory matters.

FUEL

   In connection with its operations, the Company negotiates fuel discounts with
truck stop  operators and other fuel  suppliers.  The Company stores no fuel and
has no underground storage tanks at its Phoenix and Houston facilities. However,
a lessee of the  Company  conducts a fuel  service  business  and stores fuel in
underground storage tanks at Knight's recently acquired  Indianapolis  property.
The Company has not used derivative  products to hedge against increases in fuel
costs and has no current  plans to use any  derivative  products  in the future.
Increases in fuel costs,  which began in the latter part of the first quarter of
1996, may increase the Company's  operating  expenses in subsequent  quarters to
the extent such increases  cannot be passed  through to customers.  Although the
Company usually seeks rate increases to offset fuel  increases,  excess capacity
in the  trucking  industry  may limit the  Company's  ability to  maintain  rate
increases  or pass through  increases in fuel costs.  Increases in fuel taxes or
fuel prices could have a direct  effect on the  Company's  operating  results if
increases  cannot be passed on to  customers.  Similarly,  any increases in fuel
taxes  or  fuel  prices  could  also  adversely  affect  the   profitability  of
independent contractors and the Company's cost of retaining such contractors, to
the extent such increases could not be passed along to the Company's  customers.
See  "Risk  Factors  -- Fuel"  and  "Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operations -- Inflation." 

COMPETITION

   The Company  competes  primarily  with other  regional  short to  medium-haul
truckload carriers,  logistics  providers,  national carriers and other national
equipment providers.  Railroads and air freight also provide competition, but to
a lesser degree. The Company believes that the principal  competitive factors in
its business are service,  pricing and the  availability  and  configuration  of
equipment  that meets a variety of  customers'  needs.  Recently,  the  trucking
industry, including the short to medium-haul truckload market, has been affected
by an availability of excess revenue  equipment,  which has negatively  affected
both equipment  utilization and rates.  The entire  trucking  industry is highly
competitive  and  fragmented.  Competition  for the freight  transported  by the
Company is based on  freight  rates,  service  and  efficiency.  A number of the
Company's competitors have greater financial resources,  own more equipment, and
carry a larger  volume of freight  than the Company.  The Company also  competes
with  other  motor  carriers  for  the  services  of  drivers  and   independent
contractor.

PROPERTIES

   The Company's  headquarters  are located at 5601 West Buckeye Road,  Phoenix,
Arizona,  on approximately 43 acres. The Company owns approximately 35 of the 43
acres and leases the  remaining  eight acres from Randy  Knight,  an officer and
director of the Company and one if its principal  shareholders.  The term of the
Company's lease is for five years, with two options to extend for two additional
five-year  terms.  Under the lease between the Company and Mr. Knight,  the base
rent is $4,828 per month for the initial  three years of the lease and increases
by 3% on the third  anniversary of the commencement  date, the first anniversary
of each option  term,  and the third  anniversary  of the  commencement  of each
option term. See "Certain  Relationships and Related  Transactions,"  below, for
additional information.

                                       22
<PAGE>

   In early 1996,  the Company  purchased  a three acre  operations  facility in
Indianapolis.  The facility includes a truck terminal,  administrative  offices,
and dispatching and maintenance  services and will serve as a base for expanding
the Company's  operations  in the Midwest and on the East Coast.  The Company is
currently  engaged in  negotiations  to purchase a 6.5 net acre parcel of vacant
land  adjacent  to its  Indianapolis  facility  in order to  provide  for future
growth.  The  Company's  operations  near Houston are  currently  located on the
premises of one of the  Company's  significant  customers,  for whom it provides
dedicated services.

   The Company leases office facilities in California,  Oklahoma and Utah, which
it uses for fleet  maintenance,  record  keeping  and  general  operations.  The
Company also leases space in various  locations for temporary  trailer  storage.
Management  believes that  replacement  space  comparable to these facilities is
readily obtainable,  if necessary. As of March 31, 1996, the Company's aggregate
monthly rental for all leased properties was approximately $15,000.

LEGAL PROCEEDINGS

   The  Company  is party  to  ordinary  routine  litigation  incidental  to its
business  primarily  involving  claims for  personal  injury or property  damage
incurred in the  transportation of freight.  The Company maintains  insurance to
cover liabilities in amounts in excess of self-insured retentions.

   In 1994, the Company  received notice from the Equal  Employment  Opportunity
Commission  ("EEOC")  of charges  of race  discrimination  filed by two  drivers
seeking  employment as dispatchers.  The EEOC found  reasonable cause to believe
the Company had  discriminated  against the individuals and a class of similarly
situated  individuals  based on race. The EEOC also  determined that the Company
had engaged in retaliatory  conduct  against a charging  party.  The Company has
been notified by the EEOC that  conciliation  has failed with respect to the two
charges,  including  the class  charge,  and the EEOC has filed suit against the
Company alleging unlawful employment practices on the basis of race and unlawful
retaliation.  The EEOC is seeking damages on behalf of the individuals  involved
and a class  of  persons  the  Company  is  alleged  to have  failed  to hire as
dispatchers. The EEOC is also seeking injunctive relief against alleged unlawful
employment   practices,   the  institution  of  policies   providing  for  equal
employment,  pecuniary  relief  for the  affected  class,  including  back  pay,
pre-judgment  interest  and  compensation  for past  and  future  services,  and
punitive damages.  It is the Company's policy to comply with all applicable laws
relating to equal  employment  opportunity.  The Company  believes that the EEOC
claims are without  merit and that it has  defenses  to all claims.  The Company
intends to vigorously defend the claims.

   The Company's  tractor and trailer fleets are registered in Oklahoma and Utah
and operate primarily in the western United States,  including  California.  The
Company is presently  being audited by the State of  California's  Department of
Motor  Vehicles,  with  respect to the 1994,  1995,  and 1996  "mileage  years".
Although no assessment  has yet been made,  California is asserting that all the
Company's  trailers are subject to mileage based apportioned  registration,  and
that the  Company  owes  trailer  registration  fees in excess of those  amounts
previously paid. The Company intends to vigorously contest the position taken by
California.  To the extent the Company is unsuccessful in its efforts, it may be
required to pay additional  registration fees for the mileage years involved and
penalties as well as increased registration fees (relative to payments paid with
respect to prior  periods) for future  periods.  The Company  believes  that the
outcome of the California audit will not have a materially adverse effect on the
Company's financial position or results of operations.

   Two of the  Company's  officers,  Kevin P.  Knight  and Gary J.  Knight,  are
engaged  in  arbitration   proceedings   with  their  former   employer,   Swift
Transportation,  Inc.  ("Swift") with respect to claims by Swift for damages and
injunctive  relief in  connection  with disputes  related to their  departure in
March 1990 from  employment  with Swift.  The matter has been  submitted  to the
Superior Court of the State of Arizona for definition of issues and referral for
further  arbitration  proceedings.  The  Company  is not a party to any of these
proceedings and does not believe these  proceedings  will affect its business or
financial condition.

1994 STOCK OPTION PLAN


   The  Company  maintains  a  stock  incentive  plan  (the  "Plan")  to  enable
directors, executive officers and certain key and critical line employees of the
Company,  including drivers and other employees, to participate in the ownership
of the Company. The plan will terminate on August 31, 2004. The Plan is designed
to attract and retain directors,  executive officers, key employees and critical
line  employees of the Company,  and to provide  incentives to such persons.  In
July 1994,  650,000  shares of Common  Stock were  reserved for grants under the
Plan and, at present,  648,000 shares of Common Stock are available for issuance
of stock grants made under the Plan.  Common Stock  available  for grant will be
automatically  adjusted for stock splits, stock dividends,  reverse stock splits
and similar transactions.

   The Plan has three divisions:  Division I, the Stock Option Plan,  allows the
Compensation  Committee to grant  incentive  or  nonqualified  stock  options to
employees as a traditional form of incentive compensation.  Nonqualified options
may not provide for an exercise  price of less than 85% of the fair market value
of a share of the Company's  common stock as of the date of grant. No limitation
exists on the number of shares  that may be granted  to any  individual.  Unless
otherwise  provided in the granting  agreements,  unexercised  options  lapse on
termination of employment,  except in the case of death or retirement,  in which
event the right to exercise is extended.  Division II, the Independent Directors
Automatic Stock Option Plan,  provides for the automatic grant of a stock option
to an independent  director upon such director's  appointment to the Board in an
amount not less than 2,500 shares nor more than 5,000 shares. The exercise price
of an option granted under the Independent Directors Automatic Stock Option Plan
is 85% of the fair market value of a share of the  Company's  Common Stock as of
the date of grant.  Up to 25,000  shares of the  Company's  Common  Stock may be
issued to independent  directors under the Independent Directors Automatic Stock
Option Plan.  Division III, the Employee Incentive Plan, allows the Compensation
Committee to make incentive  awards of cash or stock, or a combination  thereof,
on an annual basis, to employees who have attained  performance goals set by the
Company.  Under  this  division  of the Plan,  Common  Stock may be issued as an
incentive award for the  performance of past services.  Awards granted under the
Employee  Incentive  Plan may not exceed  $10,000 per  employee in any  calendar
year.  Stock  grants  made under one  division  of the Plan reduce the number of
shares that may be awarded under the other divisions of the Plan.

   The Plan,  other than the Independent  Directors  Automatic Stock Option Plan
Division, is administered by the Compensation Committee,  which is authorized to
select from among the eligible  employees of the Company the individuals to whom
options,  restricted  stock  purchase  rights,  or  incentive  awards  are to be
granted,  the number of shares to be awarded and the terms and conditions of the
award.  The  Independent  Directors  Automatic  Stock  Option  Plan  Division is
administered by those directors who are not entitled to participate in the Plan.
The Compensation  Committee also is authorized to adopt, amend and rescind rules
relating  to the  administration  of the Plan.  No  member  of the  Compensation
Committee  may  participate  in or take action  with  respect to any grant of an
option or stock purchase right with respect to such member.

   Shares issued by the Company under its Stock Option Plan are registered  with
the Securities and Exchange Commission and, in general, are freely tradeable.

401(k) PLAN

   The Company sponsors a 401(k) Plan (the "401(k) Plan").  The 401(k) Plan is a
profit sharing plan that permits voluntary  employee  contributions on a pre-tax
basis under section 401(k) of the Internal Revenue Code. Under the 401(k) Plan a
participant  may  elect  to defer a  portion  of his  compensation  and have the
Company contribute a portion of his compensation to the 401(k) Plan. The Company
makes a matching  contribution in an amount not to exceed fifty percent (50%) of
a participant's contributions, up to a maximum amount of $750.00 per participant
per plan year. For 1995, the Company's  contribution  was $625 per  participant.
Beginning  in 1996,  the 401(k)  Plan  allows the  Company to make its  matching
contribution in cash or in newly issued shares of the Company's  common stock or
in a combination  thereof.  The Company has reserved 75,000 shares of its Common
Stock for contributions to the 401(k) Plan. Shares to be issued under the 401(k)
Plan are registered with the Securities and Exchange Commission and, in general,
are freely tradeable.

   Under the  401(k)  Plan,  eligible  employees  have the  right to direct  the
investment  of employee  and  employer  contributions  among four mutual  funds.
Participants  may not  direct the  investment  of their  contributions  into the
Company's common stock.

   Amounts  contributed  by the  Company for a  participant  will vest over five
years and will be held in trust until  distributed  pursuant to the terms of the
401(k) Plan. Employees of the Company are eligible to participate in the

                                       27

<PAGE>
401(k) Plan if they meet certain requirements  concerning minimum age and period
of service. Distributions from participant accounts will not be permitted before
age 59 1/2 ,  except  in the  event  of  death,  disability,  certain  financial
hardships or termination of employment.

COMPENSATION COMMITTEE INTERLOCKS

   COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION. The Compensation
Committee  of the Board of  Directors  consists of Keith L. Turley and Donald A.
Bliss.  Mr.  Bliss also serves as the  Chairman of the  Compensation  Committee.
Members of the Compensation  Committee are neither employees,  officers,  nor 10
percent or greater shareholders of the Company.  See "Certain  Relationships and
Related  Transactions" for a description of transactions between the Company and
members of the Board of Directors or their affiliates.

                    CERTAIN RELATIONSHIPS AND TRANSACTIONS

COMPANY'S PURCHASE AND LEASE OF PROPERTIES.

   The Company's  headquarters  is located at 5601 West Buckeye  Road,  Phoenix,
Arizona,  on approximately 43 acres. The Company owns approximately 35 acres and
leases  eight  acres from Randy  Knight,  an  officer,  director  and  principal
shareholder of the Company. The Company has leased its operating facilities from
Randy Knight.  Total payments of  approximately  $70,100,  $10,000,  $54,800 and
$14,900  were made by the Company  to, or on behalf of,  Total  Warehousing  and
Randy Knight for the years ended  December 31, 1993,  1994, and 1995 and for the
three months ended March 31, 1996, respectively.

   Under the lease between the Company and Randy Knight, the base rent is $4,828
per month for the initial  three years of the lease,  and increases by 3% on the
third  anniversary of the commencement  date, the first day of each option term,
and the third  anniversary  of the  commencement  date of each option  term.  In
addition to base rent,  the lease  requires  the Company to pay its share of all
expenses,  utilities,  taxes and other charges. Under the lease, the Company and
Total  Warehousing  will continue  jointly to use portions of the premises.  The
Company has granted Randy Knight access and utility easements over its owned and
leased  properties.  The purchase and lease  agreements  between the Company and
Randy Knight  include  cross-indemnities  relating to  liabilities  and expenses
arising  from  the use and  occupancy  of the  property  by the  parties  to the
agreements.

   The Company and Total Warehousing have jointly purchased  insurance and other
products and services and have shared other costs  relating to the  operation of
their  businesses.  Costs have been allocated on a basis  consistent  with their
respective  use of the product or service.  In  addition,  the Company and Total
Warehousing  from time to time  provide  services  to each  other.  The  Company
provided  maintenance  and  shipping,  insurance  and other  services  for Total
Warehousing and was paid $238,000,  $154,000,  $62,000 by Total  Warehousing for
the years ended  December 31, 1993,  1994 and 1995 and none for the three months
ended  March  31,  1996,   respectively.   Total  Warehousing  provided  general
warehousing services to the Company and was paid $53,000,  $18,000,  $60,000 and
$10,700 by the Company for the years ended December 31, 1993,  1994 and 1995 and
for the three months ended March 31, 1996, respectively.

FUTURE TRANSACTIONS WITH AFFILIATES

   Upon completion of its initial public offering,  the Company adopted a policy
that future  transactions with affiliated  persons or entities would be on terms
no less  favorable  to the  Company  than  those  that  could be  obtained  from
unaffiliated  third  parties  on an  arm's  length  basis,  and  that  any  such
transactions would be approved by the Company's independent directors.

                       SHARES ELIGIBLE FOR FUTURE SALE


   Upon completion of this offering, the Company will have outstanding 9,902,000
shares of Common Stock. Of these shares, the 1,600,000 shares to be sold in this
offering  (1,840,000 if the  over-allotment  option is exercised) will be freely
tradeable  without  restriction or registration  under the Securities Act unless
acquired by  affiliates  of the  Company.  Of the  remaining  8,302,000  shares,
2,282,100 were freely  tradeable  without  restriction or registration  prior to
this offering and 6,819,900 are restricted shares  ("Restricted  Shares") within
the meaning of Rule 144 of the Securities Act and may not be sold in the absence
of registration  under the Securities Act unless an exemption from  registration
is available, including the exemption contained in Rule 144. There are currently
available for issuance  648,000 shares under the Company's Stock Option Plan and
75,000 shares under its 401(k) Plan. These shares, when and if issued,  would be
freely tradeable unless acquired by an affiliate of the Company.

   All of the Restricted  Shares will become  eligible for sale pursuant to Rule
144 under the Act  beginning  90 days after the date of this  Prospectus  if the
conditions of that Rule have been met. The Selling Shareholders, either in their
individual  capacities or through certain  related trusts and limited  liability
companies  established  for the  benefit  of  their  respective  families,  will
beneficially own 6,028,900 shares, or 60.9%, of the Company's outstanding Common
Stock,  after giving  effect to this  offering  and have agreed,  along with the
Company and its other officers and directors, with the Underwriters not to sell,
offer or otherwise  dispose of any of their shares for 180 days from the date of
this  Prospectus  without  the  prior  written  consent  of  Alex.  Brown & Sons
Incorporated.  After the 180 day period, all of such shares will be eligible for
sale under,  and subject to the  limitations  of, Rule 144 under the  Securities
Act. See "Principal and Selling Shareholders". 

   In general,  under Rule 144 as currently in effect,  an affiliate (or persons
whose shares are aggregated with an affiliate) who has  beneficially  owned, for
at least two years,  shares acquired  directly or indirectly from the Company or
from an  affiliate  of the Company is  entitled  to sell within any  three-month
period a number of shares  that does not  exceed  the  greater of 1% of the then
outstanding  shares of the Company's  Common Stock or the average weekly trading
volume of the Company's  Common Stock during the four calendar  weeks  preceding
such  sale.  Sales  under Rule 144 are also  subject  to certain  manner-of-sale
limitations,  notice  requirements,  and  the  availability  of  current  public
information about the Company.  However,  a person who has not been an affiliate
of the Company at any time during the three months  preceding a sale and who has
beneficially  owned his shares for at least three years is entitled to sell such
shares under Rule 144 without regard to any of the limitations of the Rule.

   No  predictions  can be made of the  effect,  if any,  that  market  sales of
Restricted Shares or the availability of Restricted Shares for sale will have on
the  market  price  prevailing  from  time  to  time.  Nevertheless,   sales  of
substantial  amounts of the shares of Common  Stock in the public  market  could
adversely  affect the market  price of the  Company's  Common  Stock.  See "Risk
Factors -- Shares Eligible for Future Sale."

                         DESCRIPTION OF CAPITAL STOCK

COMMON STOCK

   The Company is authorized to issue  100,000,000  shares of Common Stock,  par
value $0.01 per share,  of which  9,102,000  shares were issued and  outstanding
immediately prior to this offering. Upon completion of this offering,  9,902,000
shares will be issued and outstanding.

   The issued and outstanding shares of Common Stock are, and the shares offered
hereby  when issued will be,  fully paid and  non-assessable.  Holders of Common
Stock do not vote as a class, except as required by law, and, except for certain
cumulative  voting  rights,  each share is  entitled  to one vote on all matters
submitted to a vote of the shareholders.  Under the Arizona State  Constitution,
cumulative  voting is required for the election of directors.  This means that a
shareholder  has the  right  to cast as many  votes  in the  aggregate  as he is
entitled to vote under the Articles of Incorporation multiplied by the number of
directors to be elected.  A shareholder  may cast all his votes for one director
candidate or distribute such votes among two or more director candidates,  as he
sees fit.

   Holders of Common  Stock are  entitled to receive  such  dividends  as may be
declared  from  time to time by the  Board of  Directors  out of  funds  legally
available  therefor and, in the event of liquidation,  dissolution or winding up
of the  Company,  to share  ratably in all assets  remaining  after  payments of
liabilities  and  liquidation  preferences to the holders of any preferred stock
then outstanding.

   The holders of Common Stock have no preemptive  or conversion  rights and are
not subject to  assessments  by the Company.  There are no redemption or sinking
funds provisions  applicable to Common Stock and holders of Common Stock have no
preference in liquidation. The rights of the holders of Common Stock are subject
to the  rights  of  holders  of any  preferred  stock  that may be issued in the
future.

PREFERRED STOCK

   The Company's  Articles of Incorporation  authorize the Board of Directors to
issue 50,000,000 preferred shares, par value $0.01 (the "Preferred Shares"),  in
one or more classes and to establish the preferences  and rights  (including the
right to vote and the right to convert  into the  Common  Stock) of any class of
Preferred Shares issued. No Preferred Shares will be issued or outstanding as of
the  closing of the  offering,  and the  Company  has no present  plans to issue
Preferred Shares.

CERTAIN PROVISIONS OF THE ARTICLES OF INCORPORATION AND BYLAWS

   A number of provisions of the Articles of Incorporation  and Bylaws deal with
matters of corporate governance and the rights of shareholders.  The Articles of
Incorporation  provide the Board of  Directors  the  ability to issue  shares of
preferred  stock and to set the  voting  rights,  preferences  and  other  terms
thereof.  The ability of the Board of  Directors  to  authorize  the issuance of
preferred  stock may have an  anti-takeover  effect and may discourage  takeover
attempts  not first  approved by the Board of  Directors  (including  a takeover
which  certain  shareholders  may deem to be in their  best  interests).  To the
extent takeover  attempts are  discouraged,  fluctuations in the market price of
the  Company's  Common Stock,  which may result from actual or rumored  takeover
attempts, will be inhibited.

   Knight's Articles of Incorporation  provide that the consent of those persons
holding 67% of the Company's issued and outstanding  voting shares,  voting as a
single class, is required to approve any transaction to sell  substantially  all
of the  Company's  assets or to merge or  consolidate  the Company  with another
corporation  in a  transaction  in  which  shares  of the  Company's  stock  are
converted into cash or the right to receive other  consideration in exchange for
their shares of the Company.

   Indemnification.  The Articles of Incorporation and the Bylaws of the Company
provide that  directors of the Company will be indemnified by the Company to the
fullest  extent not  prohibited  by Arizona  law, as it now exists or may in the
future be amended,  against all expenses and liabilities  reasonably incurred in
connection  with  service  for or on  behalf of the  Company.  The  Articles  of
Incorporation  also  require  that the  Company  advance  expenses to defend any
claim, subject to a director agreeing to reimburse the Company for such advances
in the event indemnity is not permitted.  The Articles of Incorporation  and the
Bylaws  also  provide  that the right of  directors  to  indemnification  is not
exclusive  of any other right now  possessed  or  hereafter  acquired  under any
statute, agreement or otherwise.

                                       31

<PAGE>

   The Company has entered into  agreements to provide  indemnification  for its
directors  (including  actions in their capacity as officers) in addition to the
indemnification  provided for in the Articles of  Incorporation  and the Bylaws.
These agreements,  among other things,  indemnify the Company's directors to the
fullest  extent not prohibited by Arizona law, for certain  expenses  (including
attorneys'  fees),  judgments,  fines and  settlement  amounts  incurred by such
person in any action or  proceeding,  including any action by or in the right of
the  Company,  on account of services as a director or officer of the Company or
any subsidiary of the Company,  or as a director or officer of any other company
or  enterprise  to which the  person  provides  services  at the  request of the
Company,  subject  to  reimbursement  if  it  is  subsequently  determined  that
indemnification  is not  permitted.  The Company must also advance the costs and
expenses of directors seeking to enforce their rights under the  indemnification
agreements,  and cover  directors  under the  Company's  directors  and officers
liability insurance, to the extent insurance coverage is available on reasonable
terms. Although the form of the indemnification  agreements offers substantially
the  same  scope  of  coverage   afforded  by  provisions  in  the  Articles  of
Incorporation  and the Bylaws,  it provides greater  assurance to directors that
indemnification will be available, because, as a contract, it cannot be modified
unilaterally  by the Board of Directors or by the  shareholders to eliminate the
rights it provides. This provision does not affect a director's responsibilities
under  certain  other  laws,  such as the  federal  securities  laws or state or
federal  environmental  laws.  There  is no  pending  litigation  or  proceeding
involving  any  director  of the  Company as to which  indemnification  is being
sought,  and the  Company is not aware of any pending or  threatened  litigation
that may result in claims for indemnification by a director,  officer,  employee
or other agent. 

   Limitation of Liability. The Articles of Incorporation provide that directors
of the Company will not be personally liable for monetary damages to the Company
for certain breaches of their fiduciary duty as directors,  unless they violated
their duty of loyalty to the  Company or its  shareholders,  acted in bad faith,
knowingly or intentionally  violated the law, authorized the unlawful payment of
dividends or redemptions, derived an improper personal benefit from their action
as  directors,  or engaged  in  certain  transactions  involving  a conflict  of
interest. This provision has no effect on the availability of equitable remedies
or  non-monetary  relief,  such as an injunction or rescission for breach of the
duty of care.  In  addition,  the  provision  applies  only to claims  against a
director  arising  out of his role as a director  and not in any other  capacity
(such as an  officer  or  employee  of the  Company).  Further,  liability  of a
director for violations of the federal  securities  laws or  environmental  laws
will  not  be  limited  by  this  provision.  Directors  will,  however,  not be
personally  liable  for  monetary  damages  arising  from  decisions   involving
violations  of the duty of care,  including  conduct  that  could be  considered
grossly negligent.

TRANSFER AGENT

   First Interstate Bank of Arizona, N.A. has been appointed transfer agent
and registrar for the Company's Common Stock.

   The Underwriting  Agreement provides that the obligations of the Underwriters
are  subject to certain  conditions  precedent  and that the  Underwriters  will
purchase all of the shares of Common Stock offered  hereby if any of such shares
are purchased.

   The  Company  and  the  Selling   Shareholders   have  been  advised  by  the
Representatives  of the Underwriters that the Underwriters  propose to offer the
shares of Common Stock  directly to the public at the public  offering price set
forth on the cover page of this  Prospectus and to certain dealers at such price
less a concession not in excess of $. per share. The Underwriters may allow, and
such dealers may reallow,  a concession not in excess of $. per share to certain
other dealers. After commencement of the offering, the public offering price and
other selling terms may be changed by the Representatives.

   The  Selling  Shareholders  have  granted  to  the  Underwriters  an  option,
exercisable  not  later  than 30 days  after  the  date of this  Prospectus,  to
purchase up to 240,000  additional shares of Common Stock at the public offering
price set forth on the cover page of this  Prospectus.  To the  extent  that the
Underwriters  exercise such option,  each of the  Underwriters  will have a firm
commitment to purchase approximately the same percentage thereof that the number
of shares of Common  Stock to be  purchased  by it in the above  table  bears to
1,600,000,  and the  Selling  Shareholders  will be  obligated,  pursuant to the
option, to sell such shares to the  Underwriters.  The Underwriters may exercise
such option only to cover  over-allotments  made in connection  with the sale of
the shares of the Common Stock offered hereby.  If purchased,  the  Underwriters
will  sell  such  additional  shares  on the same  terms  as those on which  the
1,600,000 shares of Common Stock are being offered.

                                       33

<PAGE>
   The Underwriting  Agreement  contains covenants of indemnity and contribution
among the Underwriters, the Company and the Selling Shareholders with respect to
certain civil liabilities, including liabilities under the Securities Act.

   The Company, its officers, directors and the Selling Shareholders have agreed
not to offer, sell or otherwise dispose of any additional shares of Common Stock
for a period of 180 days  after the date of this  Prospectus  without  the prior
written consent of Alex. Brown & Sons Incorporated, except that the Company may,
without such consent, issue shares as consideration for future acquisitions. The
sales of shares by any  affiliate  is also  restricted  by Rule 144. See "Shares
Eligible for Future Sale."

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
Knight Transportation, Inc.

We  have  audited  the  accompanying   consolidated  balance  sheets  of  KNIGHT
TRANSPORTATION,  INC. (an Arizona corporation) and subsidiary as of December 31,
1994 and 1995, and the related consolidated statements of income,  shareholders'
equity and cash flows for each of the three years in the period  ended  December
31, 1995.  These financial  statements are the  responsibility  of the Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the financial position of Knight Transportation, Inc. and
subsidiary as of December 31, 1994 and 1995, and the results of their operations
and their cash flows for each of the three  years in the period  ended  December
31, 1995, in conformity with generally accepted  accounting  principles.  


                                   Arthur Andersen LLP

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

NATURE OF BUSINESS

   Knight  Transportation,  Inc.  and  Subsidiary  (the  Company)  is a short to
medium-haul,  truckload carrier of general  commodities  operating  primarily in
Arizona,  California  and other western  states.  The operations are centered in
Phoenix,  Arizona,  where the Company has its corporate offices, truck terminal,
and dispatching and maintenance  services.  The Company has recently established
operations  near  Houston,  Texas to provide  dedicated  services  to one of its
larger customers and to commence regional  services in Texas and Louisiana.  The
Company has also initiated  operations in Indianapolis,  Indiana,  from which it
will provide  regional service in the Midwest and on the East Coast. The Company
operates  predominantly  in  one  industry,  road  transportation,   subject  to
regulation by the  Department  of  Transportation  and various state  regulatory
authorities.

   The Company initiated and began to develop an independent  contractor program
during 1994. Because  independent  contractors  provide their own tractors,  the
Company views  independent  contractors  as an  alternative  method of obtaining
additional  revenue  equipment.  The Company intends to continue to increase its
use of  independent  contractors.  The  Company  had 30,  115  and 131  tractors
operated by  independent  contractors  at December 31, 1994,  1995 and March 31,
1996, respectively.

SIGNIFICANT ACCOUNTING POLICIES


   PRINCIPLES  OF  CONSOLIDATION  --  The  accompanying  consolidated  financial
statements  include the parent  company  Knight  Transportation,  Inc.,  and its
wholly owned subsidiary.  All material  intercompany items and transactions have
been eliminated in consolidation.  During the first quarter of 1996, the Company
formed three additional  wholly-owned  subsidiaries,  KTTE Holdings,  Inc., QKTE
Holdings,  Inc., and Knight  Dedicated  Services Limited  Partnership,  which is
comprised of KTTE Holdings,  Inc. as general partner and QKTE Holdings,  Inc. as
the sole limited partner. The unaudited  consolidated financial statements as of
March 31,  1996 and for the  quarter  then  ended  include  these  subsidiaries,
although they did not have significant activity.

   PREPARATION  OF  FINANCIAL   STATEMENTS  --  The   preparation  of  financial
statements in conformity with generally accepted accounting  principles requires
management to make estimates and assumptions that affect the reported amounts of
assets and  liabilities  and disclosure of contingent  assets and liabilities at
the date of the financial  statements  and the reported  amounts of revenues and
expenses  during the reporting  period.  Actual  results could differ from those
estimates.

   CASH AND CASH  EQUIVALENTS  -- The Company  considers  all highly liquid debt
instruments  purchased  with  original  maturities of three months or less to be
cash equivalents.

   INVENTORIES  AND SUPPLIES --  Inventories  and supplies  consist of tires and
spare parts which are stated at the lower of cost using the first-in,  first-out
(FIFO) method or net realizable value.

   PROPERTY  AND  EQUIPMENT  --  Property  and  equipment  are  stated  at cost.
Depreciation on property and equipment is calculated by the straight-line method
over the following estimated useful lives:


                                                             YEARS
                                                            -------

Buildings and improvements ...............................   5-20
Furniture and fixtures ...................................   5
Shop and service equipment ...............................   5
Revenue equipment ........................................   5-7
Leasehold improvements ...................................   10


   Revenue equipment is depreciated to a 10% salvage value for all trailers, and
a 15% salvage value for all tractors.

   TIRES -- Tires on revenue  equipment  purchased are  capitalized as a part of
the equipment  cost and  depreciated  over the life of the vehicle.  Replacement
tires and recapping costs are expensed when placed in service.

   INVESTMENTS IN REAL ESTATE -- During 1994 the Company  purchased  undeveloped
real property in Deer Valley,  Utah from an unrelated  third party.  The Company
then sold the property to its original  shareholders  at the original  cost plus
expenses.

                  KNIGHT TRANSPORTATION, INC. AND SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

   REVENUE  RECOGNITION -- The Company's  typical customer delivery is completed
one day after pickup.  Accordingly,  the Company  recognizes  operating revenues
when the freight is picked up for  delivery  and accrues  the  estimated  direct
costs to  complete  the  delivery.  This  method of revenue  recognition  is not
materially different from recognizing revenue based on completion of delivery.

   INCOME TAXES -- The Company uses the asset and liability method of accounting
for income taxes. Under the asset and liability method of Statement of Financial
Accounting  Standards (SFAS) No. 109, Accounting for Income Taxes,  deferred tax
assets  and  liabilities   are  recognized  for  the  future  tax   consequences
attributable to differences  between the financial  statement carrying amount of
existing  assets and liabilities  and their  respective tax bases.  Deferred tax
assets and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
be recovered  or settled.  Under SFAS No. 109, the effect on deferred tax assets
and  liabilities  of a change  in tax rates is  recognized  in the  period  that
includes the enactment date.

   CONCENTRATION  OF  CREDIT  RISK --  Financial  instruments  that  potentially
subject the Company to credit risk consist principally of trade receivables. The
Company earns revenues primarily from companies in California and Arizona.

   NET INCOME PER COMMON  SHARE -- Net income per common  share is  computed  by
dividing  net income by the weighted  average  number of common stock and common
stock equivalents  assumed outstanding during the year. Fully diluted net income
per share is  considered  equal to primary  net income per share in all  periods
presented.

   RECENTLY  ISSUED  ACCOUNTING  STANDARDS -- Statement of Financial  Accounting
Standards No. 121,  Accounting for the  Impairment of Long-Lived  Assets and for
Long-Lived  Assets to Be  Disposed  Of,  which is  required to be adopted by the
Company  in  fiscal  1996,  is not  expected  to have a  material  effect on the
Company's  financial  position  or its  results  of  operations  upon  adoption.
Statement of Financial  Accounting Standards No. 123, Accounting for Stock-Based
Compensation  (SFAS No. 123),  is also  required to be adopted by the Company in
fiscal  1996.  Pursuant  to the  provisions  of SFAS No. 123,  the Company  will
continue to account for transactions  with its employees  pursuant to Accounting
Principles  Board  Opinion No. 25,  Accounting  for Stock  Issued to  Employees.
Therefore,  this  statement  is not  expected  to have a material  effect on the
Company's financial position or its results of operations when adopted.

   FAIR VALUE OF FINANCIAL  INSTRUMENTS  -- During  October 1994,  the Financial
Accounting  Standards  Board issued SFAS No. 119,  Disclosure  about  Derivative
Financial  Instruments and Fair Value of Financial  Instruments.  This statement
requires the disclosure of estimated  fair values for all financial  instruments
for which it is practicable to estimate fair value.

   For instruments including cash, accounts receivable and payable, accruals and
line of credit, it was assumed that the carrying amount  approximated fair value
because of their short maturities.

   The fair value of long-term debt,  including  current  portion,  is estimated
based on current  rates  offered to the Company for debt of the same  maturities
and approximates the carrying amounts of long-term debt.

   INTERIM FINANCIAL  INFORMATION -- In management's  opinion,  the consolidated
financial  statements for the three-month  periods ended March 31, 1995 and 1996
include all adjustments,  consisting of normal recurring adjustments,  necessary
to present fairly the Company's  financial  position,  results of operations and
cash flows as of and for the periods then ended. Operating results for the three
month period ending March 31, 1996 are not necessarily indicative of the results
that may be expected for the fiscal year ending December 31, 1996.

                   KNIGHT TRANSPORTATION, INC. AND SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

   As of December  31, 1995,  the Company had a  $10,000,000  revolving  line of
credit with principal due at maturity,  July 1997, and interest  payable monthly
using one of three variable interest rate options selected by the Company at the
time of borrowing (prime, LIBOR plus .9%, or Certificate of Deposit plus 2.15%).
Effective  March 31, 1996, the Company's  maximum  borrowing  capacity under the
line of credit  increased to $15 million and its LIBOR  interest rate option was
adjusted to LIBOR plus .75%.  Borrowings under the line of credit are limited to
80% of eligible accounts receivable, as defined, and 50% of net fixed assets, as
defined and amounted to $2,000,000 at December 31, 1995, and $5,000,000 at March
31, 1996.


   Under the terms of the line of credit,  the  Company is  required to maintain
certain  financial  ratios.  These ratios are the total liabilities to net worth
ratio,  current  ratio,  and certain  debt service  ratios.  The Company is also
required to maintain  certain other financial  conditions  relating to corporate
structure, ownership and management. As of December 31, 1995, the Company was in
compliance  with all  covenants.  As of  March  31,  1996,  the  Company  was in
technical  default of certain financial  covenants,  for which it has received a
letter of waiver from the lender. 

   The weighted  average  interest rate on these notes payable was 7.08%,  7.50%
and 6.66% at December 31, 1994, 1995 and March 31, 1996, respectively.

(5) COMMITMENTS AND CONTINGENCIES:

LEASES

   The Company leased its  facilities  from Total  Warehousing,  Inc., a related
party, on a 32-month  cancellable lease through October 1994. Beginning November
1994 the Company entered into a five year lease with a shareholder (see Note 7).
In addition,  the Company  leased  three  tractors  under an operating  lease at
$3,885 per month during 1994.  These  tractors were purchased and traded in June
1994.

PURCHASE COMMITMENTS

   As of December  31,  1995,  and March 31,  1996,  the  Company  had  purchase
commitments for additional tractors and trailers for an estimated purchase price
of $13,000,000, and $12,200,000, respectively.

   Although Knight expects to take delivery of this revenue equipment, delays in
the  availability  of equipment  could occur due to factors beyond the Company's
control.  Any delay or  interruption  in the  availability  of  equipment in the
future could have a material adverse effect on the Company.

   The  Company is in the  process of  acquiring  both a  terminal  facility  in
Indianapolis, Indiana for approximately $1,000,000 and approximately 15 acres of
land adjacent to the Company's Phoenix facility for approximately $1,000,000.

DISABILITY PLAN

   The Company has a disability plan for certain of its key employees.  The plan
provides  disability  benefits  of $75,000  annually  for sixty  months if a key
employee terminates by reason of disability.  The plan is subject to termination
at any time by the Board of Directors.

OTHER

   The Company's  tractor and trailer fleets are registered in Oklahoma and Utah
and operate primarily in the western United States,  including  California.  The
Company is presently  being audited by the State of  California's  Department of
Motor Vehicles with respect to 1994,  1995 and 1996 mileage  years.  Although no
assessment  has yet been made,  California  is asserting  that all the Company's
trailers  are  subject  to  apportioned  registration,   and  the  Company  owes
additional  trailer  registration fees in excess of the amounts previously paid.
The Company  believes that the outcome of the  California  audit will not have a
materially  adverse  effect on the  Company's  financial  position or results of
operations.  The Company  intends to  vigorously  contest the position  taken by
California.  To the extent the Company is not successful in its efforts,  it may
be required to pay additional  registration  fees for the mileage years involved
and  possible  penalties  as well as increased  registration  fees  (relative to
payments previously paid) for future periods.

<PAGE>
                   KNIGHT TRANSPORTATION, INC. AND SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

   The Company is involved in certain  administrative  legal proceedings arising
in the normal course of business.  In the opinion of  management,  the Company's
potential exposure under the pending  proceedings is adequately  provided for in
the accompanying consolidated financial statements.

(6) CLAIMS ACCRUAL:


   Under an agreement with its insurer,  the Company acts as a self-insurer  for
bodily injury and property  damage claims up to $100,000 per single  occurrence.
Beginning in 1995, the Company is  self-insured  for workers'  compensation  for
claims up to $250,000 per single  occurrence  in states in which the Company has
elected to do so. The Company is also self-insured for collision,  comprehensive
and cargo liability up to $25,000 per  occurrence.  Liability in excess of these
amounts is  assumed by the  insurer,  subject to certain  coverage  limitations.
Exposure  greater than  individual  coverage  limitations  is insured  under the
Company's umbrella liability policy.


   The claims accrual represents accruals for the estimated uninsured portion of
pending claims  including  adverse  development of known claims and incurred but
not reported claims.  These estimates are based on historical  information along
with certain assumptions about future events.  Changes in assumptions as well as
changes in actual  experience  could cause these estimates to change in the near
term. The agreements  with the  underwriters  are  collateralized  by letters of
credit  totaling  $650,000.  These  letters  of  credit  reduces  the  available
borrowings under the Company's line of credit (see Note 4).

(7) RELATED PARTY TRANSACTIONS:

   The Company  leased  facilities  from Total  Warehousing,  Inc. (TWI) under a
32-month lease that was  terminated in 1994.  Terms of the lease called for rent
of $7,500 per month  until June 1992,  and $5,000 per month from July 1992 until
the end of the lease.  TWI is owned by a  shareholder  of the Company.  In March
1994,  the  Company  leased  approximately  eight acres from a  shareholder  and
officer,  "the  Shareholder",  under a five year lease, with an option to extend
for two additional  five-year terms. The lease terms include base rent of $4,828
per month for the initial  three years of the lease,  and increases of 3% on the
third  anniversary of the commencement  date, the first day of each option term,
and the third  anniversary  of the  commencement  date of each option  term.  In
addition to base rent,  the lease  requires  the Company to pay its share of all
expenses, utilities, taxes and other charges. The rent expense paid to TWI under
the former lease was $70,100 for the year ended  December 31, 1993,  and $10,000
for the year ended December 31, 1994.  Rent expense paid to the  Shareholder was
approximately  $54,800 and $14,900 for the year ended  December 31, 1995 and the
three months ended March 31, 1996, respectively.

   In September  1994,  the Company  purchased for $1,285,000  approximately  20
acres of property from the Shareholder.

   The Company provided  maintenance and shipping for TWI and was paid $238,000,
$154,000, $62,000, $45,800 and none for the years ended December 31, 1993, 1994,
1995 and the three  months  ended  March 31,  1995 and 1996,  respectively.  TWI
provided  general  warehousing  services to the  Company  and was paid  $53,000,
$18,000,  $60,000,  $3,300 and $10,700 for the years ended  December  31,  1993,
1994, 1995 and the three months ended March 31, 1995 and 1996, respectively.

(8) SHAREHOLDERS' EQUITY:

   The Company's authorized capital stock consists of 100,000,000 shares of $.01
par value common  stock.  In  addition,  the Company has  authorized  50,000,000
shares  of  $.01  par  value  preferred  stock,  none of  which  was  issued  or
outstanding at December 31, 1994, 1995 and March 31, 1996.

   In October 1994,  the Company issued 900,000 shares of common stock at $12.00
per share in its initial public  offering.  The offering  consisted of 1,800,000
shares comprised of 900,000  newly-issued Company shares and 900,000 shares from
shareholders.

(9) EMPLOYEE BENEFIT PLANS:

1994 STOCK OPTION PLAN

   The  Company  established  the 1994  Stock  Option  Plan (the 1994 Plan) with
650,000 shares of common stock reserved for issuance  thereunder.  The Plan will
terminate  on  August  31,  2004.  The  Compensation  Committee  of the Board of
Directors  administers  the stock  incentive  plan,  and has the  discretion  to
determine the  employees,  officers and  independent  directors who will receive
awards, the type of awards to be granted (incentive stock options,  nonqualified
stock options and  restricted  stock grants) and the term,  vesting and exercise
price.  Incentive  stock options will be designed to comply with the  applicable
provisions  of the  Internal  Revenue  Code (the  Code) and will be  subject  to
restrictions contained in the Code, including a requirement that exercise prices
are equal to at least 100% of the fair market value of the common  shares on the
grant date and a ten-year restriction on the option term.

   Independent  directors are not permitted to receive  incentive stock options.
Non-qualified stock options may be granted to directors,  including  independent
directors,  officers,  and  employees and will provide for the right to purchase
common  stock at a specified  price,  which may not be less than 85% of the fair
market  value on the date of grant,  and  usually  will  become  exercisable  in
installments  after the grant date.  Non-qualified  stock options may be granted
for any reasonable term. The 1994 Plan provides that each  independent  director
shall  receive,  on the  date of his  appointment  to the  Board  of  Directors,
non-qualified options to purchase not less than 2,500 nor more than 5,000 shares
of common  stock,  at an exercise  price  equal to the fair market  value of the
common stock on the date of the grant.

   No options were exercisable at December 31, 1995.

   The following summarizes the activity for the 1994 Plan:

401(k) PROFIT SHARING PLAN


   The Company has a 401(k) profit sharing plan (the Plan) for all employees who
are 19 years of age or older and have completed one year of service. The Plan as
amended in 1995 provides for an annual matching  contribution  not to exceed 50%
of the employee's  salary  contribution  up to $750.  Contributions  made by the
Company were equal to 35%,  40%,  50% and 50% for the plan years ended  December
31, 1993,  1994, 1995, and 1996,  respectively,  of the amount of the employee's
salary  deduction not to exceed $350,  $500, $625 and $625 annually per employee
for the plan years ended December 31, 1993,  1994, 1995 and 1996,  respectively.
The Plan also provides for a discretionary  matching contribution not limited to
the amount permitted under the Internal Revenue Code as deductible expenses. For
the years ended  December  31,  1993,  1994 and 1995 and the three  months ended
March 31, 1995 and 1996, there were no discretionary  contributions.  Employees'
rights to  employer  contributions  vest  after  five  years  from their date of
employment.  The Company's  matching  contribution  was  approximately  $23,500,
$40,300,  $60,000,  $20,900 and $24,800 for the years ended  December  31, 1993,
1994,  1995 and the three  months  ended March 31, 1995 and 1996,  respectively.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

   Article 13 of the Company's  Restated  Articles of Incorporation  provides as
follows:

   The Corporation shall indemnify and hold harmless its incorporators, and each
of its existing and former  directors,  to the fullest  extent not prohibited by
law,  as it now  exists or may  hereafter  be  amended,  for any and all acts or
omissions  done or omitted to be done while employed by, or acting on behalf of,
the  Corporation  or its  subsidiaries,  including  indemnity for service in the
capacity  as an  officer  of the  Corporation.  The  Corporation,  subject  to a
director  executing and delivering any undertaking  required by law to reimburse
the  Corporation  if indemnity  should not be allowed,  shall  advance costs and
expenses to defend any claim subject to  indemnification.  Without  limiting the
foregoing,  a director shall not be personally  liable to the Corporation or its
shareholders  for monetary  damages for breach of fiduciary  duty as a director,
except  as  otherwise  provided  by law;  provided  that no  provision  of these
Articles of  Incorporation  shall eliminate or limit the liability of a director
for (i) any breach of a  director's  duty of loyalty to the  Corporation  or its
shareholders,  (ii)  acts or  omissions  which  are not in good  faith  or which
involve intentional  misconduct or a knowing violation of law, (iii) authorizing
the unlawful  payment of a dividend or other  distribution on the  Corporation's
common  capital stock or the unlawful  purchase of its capital  stock,  (iv) any
transaction from which a director received an improper personal benefit,  or (v)
any  violation  of  Section  10-041  of the  Arizona  Revised  Statutes,  or any
successor provisions thereto.  The indemnification  rights provided herein shall
not be exclusive of or preclude any other rights of  indemnification  to which a
director,  officer, employee or agent may be entitled,  whether pursuant to law,
bylaws or agreement.

   Section 7 of the Company's Amended and Restated Bylaws provides as follows:

   Indemnification. The corporation shall indemnify and save harmless all of its
existing and former  directors  from and against all expenses  incurred by them,
including,  but not limited to, legal fees,  judgments,  penalties,  and amounts
paid in settlement or  compromise,  to the fullest extent not prohibited by law,
as it now exists or may hereafter be amended, in connection with any proceeding,
actual  or  threatened,  to which  they may be made a party by  reason  of their
service to or at the  request  of the  corporation,  including  service in their
capacity as officers,  unless it is established that: (i) the act or omission of
the indemnified party was committed in bad faith; (ii) the indemnified party did
not believe such act or omission to be in, or not opposed to, the best interests
of  the  corporation;  (iii)  in  the  case  of  any  criminal  proceeding,  the
indemnified  party had reasonable  cause to believe that the act or omission was
unlawful; or

                                      II-1

<PAGE>

(iv) the indemnified party is adjudged to be liable to the corporation  unless a
court of  competent  jurisdiction  determines  that such  person is  entitled to
indemnity.  The corporation shall advance to any person seeking  indemnification
pursuant  to Section 7.1  expenses,  including  attorneys'  fees,  actually  and
reasonably  incurred  in  defending  any  civil  or  criminal  action,  suit  or
proceeding  in  advance  of any  final  disposition  of  such  action,  suit  or
proceeding  upon  receipt  of an  undertaking  by or on behalf  of the  director
seeking indemnification to repay such amount if it is ultimately determined that
he is not  entitled  to be  indemnified  by the  corporation.  In the  event the
corporation  is  requested  to  indemnify  an  existing  or former  director  in
connection with any threatened, pending or completed action or suit by or in the
right of the corporation to procure  judgment in its favor by reason of the fact
that  such  person  was a  director,  officer,  or  employee  or  agent  of  the
corporation,  or is or was  serving at the  request of the  corporation  in such
capacity,   the  corporation  shall  indemnify  such  person  against  expenses,
including  attorneys'  fees, but excluding  judgments and fines, and for amounts
paid in settlement,  actually and reasonably  incurred by him in connection with
the defense or  settlement  of such action or suit,  if such  person  acted,  or
failed to act, in good faith and in a manner he reasonably believed to be in, or
not  opposed  to,  the  best  interests  of  the  corporation,  except  that  no
indemnification  shall be made in respect  to any  claim,  issue or matter as to
which such  person  shall have been  adjudged  to be liable to the  corporation,
unless  and only to the  extent  that a court in which  such  action or suit was
brought shall  determine,  upon  application,  that despite the  adjudication of
liability,  but in view of all  circumstances of the case, such person is fairly
and  reasonably  entitled to indemnity for such  expenses  which the court shall
deem to be proper.

   Determination by Board. Whenever any existing or former director shall report
to the President that he has incurred or may incur expenses described in Section
7.1, the Board of Directors  (other than any interested  director) shall, at its
next  regular  meeting or at a special  meeting  held within a  reasonable  time
thereafter,  determine whether, in regard to the matter involved,  the person in
question is entitled to  indemnification  pursuant to Section  7.l. If the Board
determines that the standards of Section 7.1 are met,  indemnification  shall be
made.  In the event the Board of Directors  refuses to indemnify a person who is
determined   by  a  court  of   competent   jurisdiction   to  be   entitled  to
indemnification  under Section 7.1 or applicable law, the corporation  shall, in
addition to extending  such  indemnification,  reimburse the person  entitled to
indemnification  for all attorneys'  fees and costs of court actually  incurred.
The corporation shall have the right to refuse  indemnification  in any instance
in which the person to whom  indemnification  would otherwise have been extended
unreasonably refuses to cooperate in the investigation or defense of such matter
or to permit the corporation,  at its own expense,  to retain counsel of its own
choosing to defend him.

   The Company  has entered  into  indemnification  agreements  with each of its
directors that  requires,  among other things,  that the Company  indemnify each
director  to the  fullest  extent  not  prohibited  by  Arizona  law,  including
indemnity  for a director's  service in his capacity as an officer,  and advance
all related  fees and  expenses to the  directors  and  officers,  subject to an
agreement  to  reimburse  the  Company  if it is  subsequently  determined  that
indemnification is not permitted.

ITEM 17. UNDERTAKINGS

   Insofar as indemnification  for liabilities  arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the registrant of expenses incurred
or paid by a director,  officer or  controlling  person of the registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

   The undersigned registrant hereby undertakes that:

   1. For purposes of  determining  any liability  under the  Securities  Act of
1933, the information  omitted from the form of prospectus filed as part of this
registration  statement  in reliance  upon Rule 430A and  contained in a form of
prospectus  filed by the registrant  pursuant to Rule 424(b)(1) or (4) or 497(h)
under  the  Securities  Act  shall  be  deemed  to be part of this  registration
statement as of the time it was declared effective.

   2. For the purpose of determining  any liability  under the Securities Act of
1933, each post-effective  amendment that contains a form of prospectus shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                              POWER OF ATTORNEY

attorneys-in-fact with full power of substitution and resubstitution, to execute

individually  and  in  each  capacity  stated  below,  any  and  all  amendments
(including  post-effective  amendments)  to this  Registration  Statement as the
attorney-  in-fact and to file any such amendment to the Registration  Statement
with   the   Securities   and   Exchange   Commission,    granting   unto   said
attorneys-in-fact  and their  substitutes,  full power and  authority  to do and
perform  each and every  act and thing  requisite  and  necessary  to be done in
connection  therewith,  as fully as he  might  or  could  do in  person,  hereby
ratifying and confirming all that said  attorneys-in-fact  and their substitutes
may lawfully do or cause to be done by virtue hereof.

                                                                          , 1996

MORGAN KEEGAN & COMPANY, INC.
WILLIAM BLAIR & COMPANY, L.L.C.
As Representatives of the Several Underwriters
c/o Alex. Brown & Sons Incorporated
135 East Baltimore Street
Baltimore, Maryland 21202

Gentlemen:

     Knight  Transportation,  Inc. an Arizona  corporation (the "Company"),  and
certain shareholders of the Company identified on Schedule II hereto,  either in
their  individual  capacity  or  through  related  trusts or  limited  liability
companies  as  identified  on Schedule II hereto  (the  "Selling  Shareholders")
propose  to sell to the  several  underwriters  (the  "Underwriters")  named  in
Schedule   I  hereto   for  whom  you  are   acting  as   representatives   (the
"Representatives")  an  aggregate of 1,600,000  shares of the  Company's  Common
Stock, $.01 par value (the "Firm Shares"),  of which 800,000 shares will be sold
by the Company and 800,000 shares will be sold by the Selling Shareholders.  The
respective  amounts  of the  Firm  Shares  to be so  purchased  by  the  several
Underwriters  are set forth opposite  their names in Schedule I hereto,  and the
respective amounts to be sold by the Selling Shareholders are set forth opposite
their names in Schedule II hereto. The Company and the Selling  Shareholders are
sometimes  referred  to  herein  collectively  as  the  "Sellers."  The  Selling
Shareholders also propose to sell at the Underwriters' option an aggregate of up
to                          additional shares of the Company's Common Stock (the
"Option Shares") as set forth below.

     As the  Representatives,  you have  advised  the  Company  and the  Selling
Shareholders  (a) that you are authorized to enter into this Agreement on behalf
of the several Underwriters,  and (b) that the several Underwriters are willing,
acting  severally  and not  jointly,  to purchase the numbers of Firm Shares set
forth opposite their respective names in Schedule I, plus their pro rata portion
of the Option Shares if you elect to exercise the over-allotment option in whole
or in part for the accounts of the several Underwriters. The Firm Shares and the
Option Shares (to the extent the aforementioned  option is exercised) are herein
collectively called the "Shares."

     In  consideration  of the  mutual  agreements  contained  herein and of the
interests of the parties in the transactions  contemplated  hereby,  the parties
hereto agree as follows:

     1.   Representations   and  Warranties  of  the  Company  and  the  Selling
Shareholders.

     (a) The Company  represents  and  warrants to each of the  Underwriters  as
follows:

          (i) A  registration  statement on Form S-1 (File No. ) with respect to
     the Shares has been  carefully  prepared by the Company in conformity  with
     the requirements of the Securities Act of 1933, as amended, (the "Act") and
     the Rules and Regulations  (the "Rules and  Regulations") of the Securities
     and Exchange  Commission (the  "Commission")  thereunder and has been filed
     with the Commission.  Copies of such registration statement,  including any
     amendments thereto, the preliminary prospectuses and the final prospectuses
     (meeting the requirements of the Rules and Regulations)  contained  therein
     and the exhibits,  financial  statements and schedules,  as finally amended
     and revised,  have  heretofore  been  delivered by the Company to you. Such
     registration  statement,  together with any registration statement filed by
     the Company pursuant to Rule 462(b) of the Act, shall be referred to herein
     as the  "Registration  Statement,"  which  shall be deemed to  include  all
     information omitted therefrom in reliance upon Rule 430A and contained in

                                        1


<PAGE>

     the Prospectus referred to below, has become effective under the Act and no
     post-effective amendment to the Registration Statement has been filed as of
     the date of this Agreement.  "Prospectus"  means (a) the form of prospectus
     first filed by the Company with the Commission  pursuant to its Rule 424(b)
     or (b)  the  last  preliminary  prospectus  included  in  the  Registration
     Statement filed prior to the time it becomes effective or filed pursuant to
     Rule  424(a)  under  the  Act  that  is  delivered  by the  Company  to the
     Underwriters  for delivery to purchasers  of the Shares,  together with the
     term sheet or abbreviated term sheet filed with the Commission  pursuant to
     Rule 424(b)(7) under the Act. Each preliminary  prospectus  included in the
     Registration  Statement  prior to the time it becomes  effective  is herein
     referred to as a "Preliminary Prospectus."

          (ii) The Company has been duly organized and is validly  existing as a
     corporation in good standing  under the laws of the State of Arizona,  with
     corporate  power and authority to own or lease its  properties  and conduct
     its  business  as  described  in the  Registration  Statement.  Each of the
     subsidiaries  of the  Company  as listed in Exhibit 21 to Item 16(a) of the
     Registration  Statement  (collectively  the  "Subsidiaries")  has been duly
     organized and is validly  existing as a corporation  in good standing under
     the laws of the jurisdiction of its incorporation, with corporate power and
     authority  to own or lease its  properties  and  conduct  its  business  as
     described in the Registration  Statement;  the Company and the Subsidiaries
     are duly qualified to transact  business in all  jurisdictions in which the
     conduct of their  business  requires such  qualification;  the  outstanding
     shares  of  capital  stock  of  each of the  Subsidiaries  have  been  duly
     authorized and validly issued,  are fully paid and  non-assessable  and are
     owned by the  Company  or another  Subsidiary  free and clear of all liens,
     encumbrances  and  equities and claims;  and no options,  warrants or other
     rights  to  purchase,  agreements  or other  obligations  to issue or other
     rights to convert any obligations into shares of capital stock or ownership
     interests  in  the  Subsidiaries  are  outstanding;  and,  other  than  the
     Subsidiaries,  the Company does not directly or indirectly beneficially own
     any  equity or other  interest  in any  corporation,  partnership,  limited
     liability company or other entity.

          (iii) The outstanding shares of Common Stock of the Company, including
     all  shares  to be  sold  by  the  Selling  Shareholders,  have  been  duly
     authorized  and validly issued and are fully paid and  non-assessable;  the
     portion of the Shares to be issued and sold by the  Company  have been duly
     authorized  and when  issued and paid for as  contemplated  herein  will be
     validly issued, fully-paid and non-assessable;  and no preemptive rights of
     stockholders  exist with respect to any of the Shares or the issue and sale
     thereof.  Neither the filing of the Registration Statement nor the offering
     or sale of the Shares as  contemplated  by this Agreement gives rise to any
     rights,  other  than  those  which have been  waived or  satisfied,  for or
     relating to the registration of any shares of Common Stock.

          (iv) The information set forth under the caption  "Capitalization"  in
     the  Prospectus  is true and  correct.  All of the  Shares  conform  to the
     description  thereof contained in the Registration  Statement.  The form of
     certificates   for  the  Shares  conforms  to  the  corporate  law  of  the
     jurisdiction of the Company's incorporation.

          (v) The  Commission  has not issued an order  preventing or suspending
     the use of any Prospectus  relating to the proposed  offering of the Shares
     nor instituted  proceedings for that purpose.  The  Registration  Statement
     contains, and the Prospectus and any amendments or supplements thereto will
     contain,  all  statements  which are required to be stated  therein by, and
     will conform, to the requirements of the Act and the Rules and Regulations.
     The Registration  Statement and any amendment  thereto do not contain,  and
     will not contain,  any untrue statement of a material fact and do not omit,
     and will not omit, to state any material fact required to be stated therein
     or necessary to make the statements therein not misleading.  The Prospectus
     and any amendments  and  supplements  thereto do not contain,  and will not
     contain,  any untrue  statement of material fact; and do not omit, and will
     not omit,  to state any  material  fact  required  to be stated  therein or
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not  misleading;  provided,  however,  that the
     Company makes no representations or warranties as to information  contained
     in or omitted from the  Registration  Statement or the  Prospectus,  or any
     such  amendment or supplement,  in reliance pon, and in conformity  with,
     written  information  furnished  to  the  Company  by or on  behalf  of any
     Underwriter  through  the  Representatives,  specifically  for  use  in the
     preparation thereof.

          (vi) The  consolidated  financial  statements  of the  Company and the
     Subsidiaries, together with related notes and schedules as set forth in the
     Registration Statement, present fairly the financial position and the

                                        2


<PAGE>

     results of  operations  and cash flows of the Company and the  consolidated
     Subsidiaries,  at the indicated dates and for the indicated  periods.  Such
     financial statements and related schedules have been prepared in accordance
     with  generally  accepted  principles of accounting,  consistently  applied
     throughout  the  periods  involved,  except as  disclosed  herein,  and all
     adjustments  necessary for a fair  presentation of results for such periods
     have been made. The summary  financial and statistical data included in the
     Registration  Statement  presents fairly the information  shown therein and
     such  dates has been  compiled  on a basis  consistent  with the  financial
     statements presented therein and the books and records of the Company.

          (vii) Arthur Andersen LLP, who have certified certain of the financial
     statements filed with the Commission as part of the Registration Statement,
     are independent public accountants as required by the Act and the Rules and
     Regulations.

          (viii) There is no action,  suit,  claim or proceeding  pending or, to
     the knowledge of the Company,  threatened against the Company or any of the
     Subsidiaries  before any court or administrative  agency or otherwise which
     if  determined  adversely to the Company or any of the  Subsidiaries  might
     result  in  any  material   adverse  change  in  the  earnings,   business,
     management, properties, assets, rights, operations, condition (financial or
     otherwise) or prospects of the Company and of the  Subsidiaries  taken as a
     whole or to  prevent  the  consummation  of the  transactions  contemplated
     hereby, except as set forth in the Registration Statement.

          (ix) The Company and the  Subsidiaries  have good and marketable title
     to all of the properties and assets  reflected in the financial  statements
     (or as  described in the  Registration  Statement)  hereinabove  described,
     subject to no lien,  mortgage,  pledge,  charge or  encumbrance of any kind
     except those reflected in such financial statements (or as described in the
     Registration  Statement)  or which are not material in amount.  The Company
     and the Subsidiaries occupy their leased properties under valid and binding
     leases conforming in all material  respects to the description  thereof set
     forth in the Registration Statement.

          (x) The Company and the  Subsidiaries  have filed all Federal,  State,
     local and foreign  income tax returns  which have been required to be filed
     and have paid all  taxes  indicated  by said  returns  and all  assessments
     received  by them or either of them to the  extent  that  such  taxes  have
     become due and are not being  contested in good faith.  All tax liabilities
     have  been  adequately  provided  for in the  financial  statements  of the
     Company.

          (xi) Since the  respective  dates as of which  information is given in
     the Registration Statement, as it may be amended or supplemented, there has
     not been  any  material  adverse  change  or any  development  involving  a
     prospective material adverse change in or affecting the earnings, business,
     management, properties, assets, rights, operations, condition (financial or
     otherwise),  or  prospects of the Company and its  Subsidiaries  taken as a
     whole,  whether or not  occurring in the ordinary  course of business,  and
     there has not been any  material  transaction  entered into or any material
     transaction  that is probable of being  entered  into by the Company or the
     Subsidiaries,  other than  transactions  in the ordinary course of business
     and changes and transactions described in the Registration Statement, as it
     may be amended or supplemented.  The Company and the  Subsidiaries  have no
     material  contingent  obligations  which are not disclosed in the Company's
     financial statements which are included in the Registration Statement.

          (xii) Neither the Company nor the  Subsidiaries  or with the giving of
     notice or lapse of time or both,  will be, in  violation  of or in  default
     under its  Charter  or  By-Laws or under any  agreement,  lease,  contract,
     indenture or other  instrument  or  obligation to which it is a party or by
     which  it, or any of its  properties,  is bound  and  which  default  is of
     material  significance in respect of the condition,  financial or otherwise
     of the  Company  and its  Subsidiaries  taken as a whole  or the  business,
     management, properties, assets, rights, operations, condition (financial or
     otherwise)  as  prospects  of the Company and the  Subsidiaries  taken as a
     whole. The execution and delivery of this Agreement and the consummation of
     the  transactions  herein  contemplated  and the  fulfillment  of the terms
     hereof will not conflict  with or result in a breach of any of the terms or
     provisions of, or constitute a default under, any indenture, mortgage, deed
     of trust or other  agreement  or  instrument  to which the  Company  or any
     Subsidiaries is a party, or of the Charter or By-Laws of the Company or any
     order, rule or regulation  applicable to the Company or any Subsidiaries of
     any  court or of any  regulatory  body or  administrative  agency  or other
     governmental body having jurisdiction.

          (xiii) Each  approval,  consent,  order,  authorization,  designation,
     declaration or filing by or with any  regulatory,  administrative  or other
     governmental body necessary in connection with the execution and

                                        3

<PAGE>

     delivery  by the  Company of this  Agreement  and the  consummation  of the
     transactions  herein  contemplated  (except such additional steps as may be
     required by the Commission, the National Association of Securities Dealers,
     Inc. (the "NASD") or such  additional  steps as may be necessary to qualify
     the Shares for public offering by the  Underwriters  under State securities
     or Blue Sky  laws)  has been  obtained  or made  and is in full  force  and
     effect.

          (xiv) The  Company  and each of the  Subsidiaries  holds all  material
     licenses,  certificates and permits from governmental authorities which are
     necessary to the conduct of their  businesses;  and neither the Company nor
     any of the  Subsidiaries  has infringed any patents,  patent rights,  trade
     names,  trademarks or  copyrights,  which  infringement  is material to the
     business of the Company and the Subsidiaries taken as a whole.

          (xv) Neither the Company, nor to the Company's best knowledge,  any of
     its affiliates,  has taken or may take, directly or indirectly,  any action
     designed  to cause or result  in, or which  has been  constituted  or which
     might   reasonably  be  expected  to  constitute,   the   stabilization  or
     manipulation  of the price of the shares of Common Stock to facilitate  the
     sale or resale of the Shares.

          (xvi)  Neither  the  Company  nor  any  of  its   subsidiaries  is  an
     "investment  company"  within the meaning of such term under the Investment
     Company  Act of 1940  and  the  Rules  and  Regulations  of the  Commission
     thereunder.

          (xvii) The Company maintains a system of internal  accounting controls
     sufficient  to provide  reasonable  assurances  that (i)  transactions  are
     executed in accordance with management's general or specific authorization;
     (ii)  transactions  are  recorded as  necessary  to permit  preparation  of
     financial  statements  in conformity  with  generally  accepted  accounting
     principles  and to  maintain  accountability  for assets;  (iii)  access to
     assets  is  permitted  only in  accordance  with  management's  general  or
     specific authorization;  and (iv) the recorded accountability for assets is
     compared with  existing  assets at  reasonable  intervals  and  appropriate
     action is taken with respect to any differences.

          (xviii) The Company and each of its Subsidiaries carry, or are covered
     by,  insurance in such  amounts and covering  such risks as is adequate for
     the  conduct  of  their  respective  businesses  and  the  value  of  their
     respective  properties and as is customary for companies engaged in similar
     industries.

          (xix) The Company is in compliance  in all material  respects with all
     presently applicable  provisions of the Employee Retirement Income Security
     Act  of  1974,  as  amended,   including  the   regulations  and  published
     intepretations  thereunder ("ERISA");  no "reportable event" (as defined in
     ERISA) has  occurred  with  respect to any  "pension  plan" (as  defined in
     ERISA) for which the Company would have any liability;  the Company has not
     incurred and does not expect to incur liability under (i) Title IV of ERISA
     with respect to termination  of, or withdrawal  from, any "pension plan" or
     (ii) Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended,
     including the  regulations  and published  interpretations  thereunder (the
     "Code");  and each  "pension  plan" for which the  Company  would  have any
     liability that is intended to be qualified under Section 401(a) of the Code
     is so qualified in all material respects and nothing has occurred,  whether
     by  action  or by  failure  to act,  which  would  cause  the  loss of such
     qualification.

     (b) Each of the Selling  Shareholders  severally represents and warrants as
follows:

          (i)  Such  Selling  Shareholder  has and at the  Closing  Date and the
     Option  Closing  Date,  as the case may be (as such  dates are  hereinafter
     defined)  will have good and valid  title to the Firm Shares and the Option
     Shares to be sold by such Selling Shareholder, free and clear of any liens,
     encumbrances,  equities and claims,  and full right, power and authority to
     effect the sale and  delivery  of such Firm Shares and Option  Shares;  and
     upon the delivery  of,  against  payment  for,  such Firm Shares and Option
     Shares pursuant to this Agreement,  the Underwriters  will acquire good and
     valid title thereto,  free and clear of any liens,  encumbrances,  equities
     and claims.

          (ii) Such Selling  Shareholder has full right,  power and authority to
     execute  and  deliver  this  Agreement,  the  Power  of  Attorney,  and the
     Custodian  Agreement referred to below and to perform its obligations under
     such  Agreements.  The  execution  and delivery of this  Agreement  and the
     consummation  by  such  Selling  Shareholder  of  the  transactions  herein
     contemplated  and the fulfillment by such Selling  Shareholder of the terms
     hereof will not require any consent, approval, authorization or other order
     of any court,

                                        4

<PAGE>
     regulatory body,  administration  agency or other governmental body (except
     as may be required under the Act, state  securities  laws or Blue Sky laws)
     and will not result in a breach of any of the terms and  provisions  of, or
     constitute  a  default  under,  organizational  documents  of such  Selling
     Shareholder,  if not an  individual,  or any indenture,  mortgage,  deed of
     trust or other agreement or instrument to which such Selling Shareholder is
     a party,  or of any order,  rule or  regulation  applicable to such Selling
     Shareholder of any court or of any regulatory body or administrative agency
     or other governmental body having jurisdiction.

          (iii)  Such  Selling  Shareholder  has not  taken  and will not  take,
     directly or indirectly,  any action designed to, or which has  constituted,
     or which might  reasonably be expected to cause or result in  stabilization
     or  manipulation of the price of the Common Stock of the Company and, other
     than as permitted by the Act, the Selling  Shareholder  will not distribute
     any prospectus or other offering  material in connection  with the offering
     of the Shares.

          (iv) Such  Selling  Shareholder  will engage in no  offering,  sale or
     other  disposition  of any  Common  Stock of the  Company,  any  options or
     warrants to purchase  shares of Common Stock or any securities  convertible
     into or  exchangeable  for shares of Common  Stock for a period of 180 days
     after the date of this  Agreement,  directly or indirectly,  otherwise than
     hereunder  or  with  the  prior  written  consent  of  Alex.  Brown  & Sons
     Incorporated.

          (v) Without having undertaken to determine  independently the accuracy
     or completeness of either the representations and warranties of the Company
     contained   herein  or  the  information   contained  in  the  Registration
     Statement,  such  Selling  Shareholder  has no reason to  believe  that the
     representations  and warranties of the Company  contained in this Section 1
     are not true and correct,  is familiar with the Registration  Statement and
     has no  knowledge  of any  material  fact,  condition  or  information  not
     disclosed in the Registration Statement which has adversely affected or may
     adversely  affect the business of the Company or of the  Subsidiaries;  and
     the  sale  of the  Firm  Shares  and the  Option  Shares  by  such  Selling
     Shareholder  pursuant hereto is not prompted by any information  concerning
     the  Company  or any of the  Subsidiaries  which  is not set  forth  in the
     Registration   Statement.   The  information  pertaining  to  such  Selling
     Shareholder  under the caption "Selling  Shareholders" in the Prospectus is
     complete and accurate in all material respects.

     2. Purchase,  Sale and Delivery of the Firm Shares. (a) On the basis of the
representations,  warranties and covenants herein contained,  and subject to the
conditions  herein set forth,  the Sellers agree to sell to the Underwriters and
each Underwriter agrees, severally and not jointly, to purchase, at a price of $
per  share,  the  number  of Firm  Shares  set forth  opposite  the name of each
Underwriter  in Schedule I hereof,  subject to  adjustments  in accordance  with
Section 9 hereof.  The number of Firm Shares to be purchased by each Underwriter
from each Seller shall be as nearly as practicable in the same proportion to the
total  number of Firm  Shares  being  sold by each  Seller as the number of Firm
Shares  being  purchased by each  Underwriter  bears to the total number of Firm
Shares to be sold  hereunder.  The obligations of the Company and of each of the
Selling Shareholders shall be several and not joint.

     (b)  Certificates  in negotiable form for the total number of the Shares to
be sold hereunder by the Selling  Shareholders  have been placed in custody with
First Interstate Bank of Arizona,  N.A., as custodian (the "Custodian") pursuant
to the Custodian  Agreement and Power of Attorney  (the  "Custodian  Agreement")
executed by each  Selling  Shareholder  for  delivery of all Firm Shares and any
Option  Shares to be sold  hereunder  by the Selling  Shareholders.  Each of the
Selling  Shareholders  specifically  agrees  that the Firm Shares and any Option
Shares  represented  by  the  certificates  held  in  custody  for  the  Selling
Shareholders  under the Custodian  Agreement are subject to the interests of the
Underwriters  hereunder,  that the arrangements made by the Selling Shareholders
for such custody are to that extent irrevocable, and that the obligations of the
Selling Shareholders hereunder shall not be terminable by any act or deed of the
Selling Shareholders (or by any other person, firm or corporation  including the
Company,  the Custodian or the  Underwriters)  or by operation of law (including
the death of an individual Selling Shareholder or the dissolution of a corporate
Selling Shareholder or by the occurrence of any other event or events, except as
set forth in the  Custodian  Agreement.  If any such event should occur prior to
the  delivery  to the  Underwriters  of the Firm  Shares  or the  Option  Shares
hereunder,  certificates  for the Firm Shares or the Option Shares,  as the case
may be,  shall be delivered by the  Custodian in  accordance  with the terms and
conditions of this Agreement as if such event has not occurred. The Custodian is
authorized  to receive and  acknowledge  receipt of the  proceeds of sale of the
Shares held by it against delivery of such Shares.

                                        5

     (c) Payment for the Firm Shares to be sold  hereunder  is to be made in New
York  Clearing  House funds by certified or bank  cashier's  checks drawn to the
order of the  Company for the shares to be sold by it and to the order of "First
Interstate Bank of Arizona,  N.A. as Custodian" for the shares to be sold by the
Selling Shareholders,  in each case against delivery of certificates therefor to
the Representatives  for the several accounts of the Underwriters.  Such payment
and delivery are to be made at the offices of Alex.  Brown & Sons  Incorporated,
135 East Baltimore Street,  Baltimore,  Maryland, at 10:00 A.M., Baltimore time,
on the third business day after the date of this Agreement or at such other time
and date not later than five  business  days  thereafter  as you and the Company
shall agree upon,  such time and date being  herein  referred to as the "Closing
Date." (As used herein,  "business  day" means a day on which the New York Stock
Exchange  is open  for  trading  and on  which  banks  in New  York are open for
business  and  not  permitted  by law or  executive  order  to be  closed.)  The
certificates for the Firm Shares will be delivered in such  denominations and in
such registrations as the Representatives requests in writing not later than the
second full business day prior to the Closing Date,  and will be made  available
for  inspection  by the  Representatives  at least one business day prior to the
Closing Date.

     (d) In addition,  on the basis of the representations and warranties herein
contained and subject to the terms and conditions  herein set forth, the Selling
Shareholders listed on Schedule III hereto hereby grant an option to the several
Underwriters  to purchase the Option  Shares at the price per share as set forth
in the first paragraph of this Section 2. The maximum number of Option Shares to
be sold by the Selling Shareholders is set forth opposite their respective names
on Schedule III hereto.  The option  granted hereby may be exercised in whole or
in part by giving  written  notice (i) at any time before the  Closing  Date and
(ii) only once thereafter  within 30 days after the date of this  Agreement,  by
you, as Representatives of the several Underwriters, to the Selling Shareholders
(care of the Company) [the  Attorney-in-Fact,  and the Custodian]  setting forth
the number of Option Shares as to which the several  Underwriters are exercising
the option,  the names and  denominations  in which the Option  Shares are to be
registered and the time and date at which such certificates are to be delivered.
If the option  granted  hereby is exercised in part,  the  respective  number of
Option Shares to be sold by each of the Selling  Shareholders listed in Schedule
III  hereto  shall be  determined  on a pro rata  basis in  accordance  with the
percentages  set forth opposite their names on Schedule III hereto,  adjusted by
you in such  manner as to avoid  fractional  shares.  The time and date at which
certificates  for Option  Shares are to be delivered  shall be determined by the
Representatives  but  shall not be  earlier  than  three nor later  than 10 full
business  days after the exercise of such option,  nor in any event prior to the
Closing Date (such time and date being herein referred to as the "Option Closing
Date").  If the date of  exercise of the option is three or more days before the
Closing  Date,  the notice of exercise  shall set the Closing Date as the Option
Closing Date.  The number of Option  Shares to be purchased by each  Underwriter
shall be in the same  proportion  to the total  number of  Option  Shares  being
purchased as the number of Firm Shares being purchased by such Underwriter bears
to 1,600,000,  adjusted by you in such manner as to avoid fractional shares. The
option with respect to the Option Shares granted hereunder may be exercised only
to cover  over-allotments  in the sale of the Firm  Shares by the  Underwriters.
You, as Representatives of the several  Underwriters,  may cancel such option at
any time prior to its expiration by giving  written notice of such  cancellation
to the Selling  Shareholders (care of the Company).  To the extent, if any, that
the option is  exercised,  payment  for the Option  Shares  shall be made on the
Option  Closing  Date in New York  Clearing  House  funds by  certified  or bank
cashier's check drawn to the order of "First  Interstate Bank of Arizona,  N.A.,
as  Custodian"  for the  Option  Shares to be sold by the  Selling  Shareholders
against  delivery of certificates  therefor at the offices of Alex. Brown & Sons
Incorporated, 135 East Baltimore Street, Baltimore, Maryland. 

     (e) If on the Closing Date or Option  Closing Date, as the case may be, any
Selling  Shareholder  fails to sell the Firm Shares or Option  Shares which such
Selling  Shareholder has agreed to sell on such date as set forth in Schedule II
hereto,  the  Company  agrees  that it will sell or arrange for the sale of that
number of  shares of Common  Stock to the  Underwriters  which  represents  Firm
Shares or the Option Shares which such Selling  Shareholder  has failed to sell,
as set forth in Schedule II hereto, or such lesser number as may be requested by
the Representatives.

     3.  Offering  by  the  Underwriters.  It is  understood  that  the  several
Underwriters  are to make a public  offering  of the Firm  Shares as soon as the
Representatives  deem it advisable to do so. The Firm Shares are to be initially
offered  to the public at the  initial  public  offering  price set forth in the
Prospectus.  The  Representatives  may from time to time  thereafter  change the
public  offering price and other selling terms.  To the extent,  if at all, that
any Option Shares are purchased  pursuant to Section 2 hereof,  the Underwriters
will offer them to the public on the foregoing terms.

                                        6

<PAGE>
     It is further understood that you will act as the  Representatives  for the
Underwriters  in the offering and sale of the Shares in accordance with a Master
Agreement  Among  Underwriters  entered  into  by  you  and  the  several  other
Underwriters.

     4. Covenants of the Company and the Selling  Shareholders.  (a) The Company
covenants and agrees with the several Underwriters that:

          (i)  The  Company   will  (A)  use  its  best  efforts  to  cause  the
     Registration  Statement to become  effective  or, if the  procedure in Rule
     430A of the Rules and  Regulations is followed,  to prepare and timely file
     with the  Commission  under  Rule  424(b) of the Rules  and  Regulations  a
     Prospectus in a form approved by the Representatives containing information
     previously  omitted  at the  time  of  effectiveness  of  the  Registration
     Statement  in reliance on Rule 430A of the Rules and  Regulations,  and (B)
     not file any amendment to the  Registration  Statement or supplement to the
     Prospectus  of which the  Representatives  shall not  previously  have been
     advised and  furnished  with a copy or to which the  Representatives  shall
     have reasonably  objected in writing or which is not in compliance with the
     Rules and  Regulations  and (C) file on a timely  basis all reports and any
     definitive  proxy or  information  statements  required  to be filed by the
     Company with the  Commission  subsequent to the date of the  Prospectus and
     prior to the termination of the offering of the Shares by the Underwriters.

          (ii) The Company will advise the Representatives promptly (A) when the
     Registration  Statement or any post-effective  amendment thereto shall have
     become effective,  (B) of receipt of any comments from the Commission,  (C)
     of any  request  of  the  Commission  for  amendment  of  the  Registration
     Statement  or for  supplement  to the  Prospectus  or  for  any  additional
     information,  and (D) of the issuance by the  Commission  of any stop order
     suspending the  effectiveness of the  Registration  Statement or the use of
     the Prospectus or of the  institution of any  proceedings for that purpose.
     The Company  will use its best  efforts to prevent the issuance of any such
     stop order preventing or suspending the use of the Prospectus and to obtain
     as soon as possible the lifting thereof, if issued.

          (iii)  The  Company  will  cooperate  with  the   Representatives   in
     endeavoring  to qualify  the Shares for sale under the  securities  laws of
     such jurisdictions as the Representatives may reasonably have designated in
     writing and will make such applications,  file such documents,  and furnish
     such information as may be reasonably  required for that purpose,  provided
     the Company shall not be required to qualify as a foreign corporation or to
     file a general consent to service of process in any  jurisdiction  where it
     is not now so  qualified  or required  to file such a consent.  The Company
     will, from time to time,  prepare and file such  statements,  reports,  and
     other documents,  as are or may be required to continue such qualifications
     in  effect  for so long a  period  as the  Representatives  may  reasonably
     request for distribution of the Shares.

          (iv)  The  Company  will  deliver  to,  or  upon  the  order  of,  the
     Representatives,  from  time to time,  as many  copies  of any  Preliminary
     Prospectus as the Representatives may reasonably request.  The Company will
     deliver  to, or upon the order of,  the  Representatives  during the period
     when delivery of a Prospectus is required  under the Act, as many copies of
     the Prospectus in final form, or as thereafter amended or supplemented,  as
     the Representatives may reasonably request. The Company will deliver to the
     Representatives  at or before the Closing  Date,  four signed copies of the
     Registration  Statement and all amendments  thereto  including all exhibits
     filed  therewith,  and will deliver to the  Representatives  such number of
     copies of the  Registration  Statement  (including such number of copies of
     the exhibits filed therewith that may reasonably be requested),  and of all
     amendments thereto, as the Representatives may reasonably request.

          (v)  The  Company   will  comply  with  the  Act  and  the  Rules  and
     Regulations,  and the  Securities  Exchange  Act of 1934,  as amended  (the
     "Exchange   Act"),   and  the  rules  and  regulations  of  the  Commission
     thereunder,  so as to permit  the  completion  of the  distribution  of the
     Shares as contemplated in this Agreement and the Prospectus.  If during the
     period in which a  prospectus  is  required  by law to be  delivered  by an
     Underwriter  or dealer any event shall  occur as a result of which,  in the
     judgment of the Company or in the reasonable  opinion of the  Underwriters,
     it becomes necessary to amend or supplement the Prospectus in order to make
     the statements therein,  in the light of the circumstances  existing at the
     time the Prospectus is delivered to a purchaser, not misleading,  or, if it
     is necessary at any time to amend or  supplement  the  Prospectus to comply
     with  any  law,  the  Company  promptly  will  prepare  and  file  with the
     Commission  an  appropriate  amendment  to the  Registration  Statement  or
     supplement  to the  Prospectus  so that the  Prospectus  as so  amended  or
     supplemented  will  not,  in the light of the  circumstances  when it is so
     delivered, be misleading, or so that the Prospectus will comply with law.

                                        7
<PAGE>
          (vi)  The  Company  will  make  generally  available  to its  security
     holders,  as soon as it is practicable to do so, but in any event not later
     than 15 months after the effective date of the Registration  Statement,  an
     earnings  statement  (which  need not be  audited)  in  reasonable  detail,
     covering a period of at least 12  consecutive  months  beginning  after the
     effective date of the Registration Statement, which earning statement shall
     satisfy the  requirements  of Section  11(a) of the Act and Rule 158 of the
     Rules and  Regulations  and will advise you in writing when such  statement
     has been so made available.
       
          (vii) The  Company  will,  for a period of five years from the Closing
     Date, deliver to the Representatives copies of annual reports and copies of
     all other  documents,  reports and information  furnished by the Company to
     its  stockholders  or filed with any  securities  exchange  pursuant to the
     requirements of such exchange or with the Commission pursuant to the Act or
     the Exchange Act. The Company will deliver to the  Representatives  similar
     reports with respect to significant  subsidiaries,  as that term is defined
     in the Rules and  Regulations,  which are not consolidated in the Company's
     financial statements.

          (viii) No  offering,  sale,  short  sale or other  disposition  of any
     shares of Common Stock of the Company, or other securities convertible into
     or  exchangeable or exercisable for shares of Common Stock or derivative of
     Common Stock (or  agreement for such) will be made for a period of 180 days
     after the date of this  Agreement,  directly or indirectly,  by the Company
     otherwise than hereunder or with the prior written consent of Alex. Brown &
     Sons Incorporated,  except that the Company may, without such consent,  (i)
     issue options and shares  pursuant to the 1994 Stock Option Plan  described
     in the Registration  Statement and (ii) issue shares as  consideration  for
     future  acquisitions,  provided  that each  recipient of such shares in any
     such  acquisition   agrees  in  writing  to  be  subject  to  the  transfer
     restrictions  imposed  pursuant to this  Section 4 (viii) to the extent the
     day period following the date of this Agreement has not expired.
         
          (ix) The Company will use its best efforts to list,  subject to notice
     of issuance, the Shares on The Nasdaq Stock Market.

          (x) The Company has caused each  officer  and  director  and  specific
     shareholders  of the  Company to furnish to you, on or prior to the date of
     this agreement,  a letter or letters, in form and substance satisfactory to
     the  Underwriters,  pursuant to which each such  person  shall agree not to
     offer,  sell, sell short or otherwise dispose of any shares of Common Stock
     of the  Company  or  other  capital  stock  of the  Company,  or any  other
     securities  convertible,  exchangeable  or exercisable for Common Shares or
     derivative   of  Common   Shares  owned  by  such  person  or  request  the
     registration  for the offer or sale of any of the foregoing (or as to which
     such person has the right to direct the disposition of) for a period of 180
     days after the date of this Agreement,  directly or indirectly, except with
     the prior  written  consent  of Alex.  Brown & Sons  Incorporated  ("Lockup
     Agreements"). 

          (xi) The  Company  shall  apply  the net  proceeds  of its sale of the
     Shares as set forth in the Prospectus.

          (xii) The Company  shall not  invest,  or  othewise  use the  proceeds
     received  by the  Company  from its sale of the  Shares in such a manner as
     would  require  the  Company or any of the  Subsidiaries  to register as an
     investment  company  under the  Investment  Company Act of 1940, as amended
     (the "1940 Act").

          (xiii) The Company  will  maintain a transfer  agent and, if necessary
     under the jurisdiction of incorporation of the Company, a registrar for the
     Common Stock.

          (xiv) The Company will not take,  directly or  indirectly,  any action
     designed to cause or result in, or that has constituted or might reasonably
     be expected to constitute,  the  stabilization or manipulation of the price
     of any securities of the Company.

     (b) Each of the Selling Shareholders  covenants and agrees with the several
Underwriters that:

          (i) No offering,  sale, short sale or other  disposition of any shares
     of Common  Stock of the  Company or other  capital  stock of the Company or
     other securities convertible,  exchangeable or exercisable for Common Stock
     or derivative of Common Stock owned by the Selling  Shareholder  or request
     the  registration  for the offer or sale of any of the  foregoing (or as to
     which the Selling  Shareholder  has the right to direct the disposition of)
     will be made for a period  of 180 days  after  the date of this  Agreement,
     directly  or  indirectly,   by  such  Selling  Shareholder  otherwise  than
     hereunder  or  with  the  prior  written  consent  of  Alex.  Brown  & Sons
     Incorporated.

          (ii) In  order  to  document  the  Underwriters'  compliance  with the

     of 1983

                                        8

     with respect to the transactions herein  contemplated,  each of the Selling
     Shareholders  agrees to  deliver to you prior to or at the  Closing  Date a
     properly completed and executed United States Treasury  Department Form W-9
     (or other  applicable  form or statement  specified by Treasury  Department
     regulations in lieu thereof).

          (iii) Such Selling  Shareholder will not take, directly or indirectly,
     any action designed to cause or result in, or that has constituted or might
     reasonably be expected to constitute,  the stabilization or manipulation of

     5. Costs and  Expenses.  The Company will pay all costs,  expenses and fees

for the  Underwriters,  incurred in  connection  with the  qualification  of the
Shares under State securities or Blue Sky laws. The Company shall not,  however,
be  required  to pay for any of the  Underwriters'  expenses  (other  than those
related to qualification  under NASD regulation and State securities or Blue Sky
laws)  except  that,  if this  Agreement  shall not be  consummated  because the
conditions in Section 6 hereof are not  satisfied,  or because this Agreement is
terminated by the Representatives pursuant to Section 11 hereof, or by reason of
any  failure,  refusal or  inability  on the part of the  Company or the Selling
Shareholders  to perform  any  undertaking  or  satisfy  any  condition  of this
Agreement  or to  comply  with  any of the  terms  hereof  on  their  part to be
performed,  unless such failure to satisfy said condition or to comply with said
terms be due to the  default or omission  of any  Underwriter,  then the Company
shall reimburse the several Underwriters for reasonable  out-of-pocket expenses,
including fees and disbursements of counsel,  reasonably  incurred in connection
with  investigating,  marketing  and  proposing  to  market  the  Shares  or  in

Selling  Shareholders  shall not in any  event be  liable to any of the  several
Underwriters for damages on account of loss of anticipated profits from the sale
by them of the Shares.

     6. Conditions of Obligations of the Underwriters.  The several  obligations
of the  Underwriters  to purchase  the Firm  Shares on the Closing  Date and the
Option  Shares,  if any, on the Option Closing Date are subject to the accuracy,

representations  and  warranties  of the Company  and the  Selling  Shareholders
contained  herein,  and to  the  performance  by the  Company  and  the  Selling
Shareholders of their  covenants and obligations  hereunder and to the following
additional conditions: 

          (a)  The  Registration  Statement  and all  post-effective  amendments

     Subsidiaries are duly qualified to transact  business in all  jurisdictions
     in which the conduct of their business requires such  qualification,  or in

     agreements  or other  obligations  to issue or other  rights to convert any
     obligations  into any shares of capital stock or of ownership  interests in

     and sale thereof.

          (iii) Except as described in or contemplated by the Prospectus,  or in
     documents previously filed with the Commission as exhibits and incorporated
     into  the Registration  Statement,  to the knowledge of such counsel, there
     are no outstanding  securities of the Company  convertible or  exchangeable
     into or  evidencing  the right to purchase or  subscribe  for any shares of
     capital  stock of the Company and there are no  outstanding  or  authorized
     options,  warrants  or rights of any  character  obligating  the Company to
     issue any shares of its  capital  stock or any  securities  convertible  or
     exchangeable  into or evidencing the right to purchase or subscribe for any
     shares of such stock;  and except as  described in the  Prospectus,  to the
     knowledge of such  counsel,  no holder of any  securities of the Company or
     any other person has the right,  contractual  or  otherwise,  which has not
     been  satisfied  or  effectively  waived,  to cause the  Company to sell or
     otherwise  issue to them, or to permit them to underwrite  the sale of, any
     of the Shares or the right to have any Common Shares or other securities of
     the  Company  included in the  Registration  Statement  or the right,  as a
     result of the filing of the Registration Statement, to require registration
     under  the Act of any  shares of Common  Stock or other  securities  of the
     Company.

          (iv) The  Registration  Statement has become  effective  under the Act
     and, to the best of such  counsel's  knowledge,  no stop order  proceedings
     with respect  thereto  have been  instituted  or are pending or  threatened
     under the Act.

          (v) The Registration  Statement,  the Prospectus and each amendment or
     supplement  thereto  comply as to form in all  material  respects  with the
     requirements of the Act and the applicable Rules and Regulations thereunder
     (except  that such  counsel  need  express no  opinion as to the  financial
     statements and related schedules  therein).  [The conditions for the use of
     Form  S-1,  set  forth  in the  General  Instructions  thereto,  have  been
     satisfied.]

          (vi) The statements  under the captions "Risk Factors --  Regulation,"
     "Business -- Regulation," "-- Safety and Risk Management," "-- Properties,"
     "-- Legal  Proceedings,"  "Management  -- 1994 Stock  Incentive  Plan," "--
     401(k) Plan,"  "Certain  Transactions,"  "Description of Capital Stock" and
     "Shares  Eligible  for  Future  Sale" in the  Prospectus,  insofar  as such
     statements constitute a summary of documents referred to therein or matters
     of law, fairly  summarize in all material  respects the information  called
     for with respect to such documents and matters.

          (vii)  Such  counsel  does  not  know of any  contracts  or  documents
     required to be filed as exhibits to the Registration Statement or described
     in the  Registration  Statement or the Prospectus which are not so filed or
     described as required,  and such  contracts and documents as are summarized
     in the  Registration  Statement or the Prospectus are fairly  summarized in
     all material respects.

          (viii)  Such  counsel  knows  of no  material  legal  or  governmental
     proceedings  pending  or  threatened  against  the  Company  or  any of the
     Subsidiaries, except as set forth in the Prospectus.

          (ix) The execution and delivery of this Agreement and the consummation
     of the transactions  herein  contemplated do not and will not conflict with
     or result in a breach of any of the terms or provisions of, or constitute a
     default under,  the Charter or By-Laws of the Company,  or any agreement or
     instrument  known  to such  counsel  to  which  the  Company  or any of the
     Subsidiaries is a party or by which the Company or any of the  Subsidiaries
     may be bound.

          (x) This Agreement has been duly authorized, executed and delivered by
     the Company.

          (xi)  No  approval,   consent,  order,   authorization,   designation,
     declaration or filing by or with any  regulatory,  administrative  or other
     governmental  body is  necessary  in  connection  with  the  execution  and
     delivery of this Agreement and the consummation of the transactions  herein
     contemplated  (other  than as may be required by the NASD or as required by
     State  securities  and Blue Sky laws, as to which such counsel need express
     no opinion) except such as have been obtained or made, specifying the same.

          (xii) The  Company  is not,  and will not  become,  as a result of the
     consummation  of the  transactions  contemplated  by  this  Agreement,  and
     application of the net proceeds  therefrom as described in the  Prospectus,
     required to register as an investment company under the 1940 Act.

          (xiii) This Agreement has been duly authorized, executed and delivered
     on behalf of the Selling Shareholders.

          (xiv)  Each  Selling  Shareholder  has full  legal  right,  power  and
     authority,  and any  approval  required  by law (other  than as required by
     State securities and Blue Sky laws as to which such counsel need express no
     opinion),  to sell, assign,  transfer and deliver the portion of the Shares
     to be sold by such Selling Shareholder.

          (xv) The Custodian  Agreement  and the Power of Attorney  executed and
     delivered by each Selling Shareholder is valid and binding,  except as such
     enforceability may be limited by bankruptcy, moratorium, or similar laws or
     principles of equity.

          (xvi) The  Underwriters  (assuming that they are bona fide  purchasers
     within the meaning of the Uniform  Commercial  Code) have acquired good and
     marketable  title to the Shares being sold by each Selling  Shareholder  on
     the Closing Date, and the Option Closing Date, as the case may be, free and
     clear of all liens, encumbrances, equities and claims.

     In rendering  such  opinion,  Ryley,  Carlock &  Applewhite  may rely as to
matters  governed by the laws of states  other than  Arizona or Federal  laws on
local counsel in such  jurisdictions  provided that in each case such opinion is
also addressed to the underwriters  and Ryley,  Carlock & Applewhite shall state
that they believe  that they and the  Underwriters  are  justified in relying on
such other  counsel.  In addition to the matters set forth  above,  such opinion
shall also  include a  statement  to the  effect  that  nothing  has come to the
attention of such counsel which leads them to believe that (i) the  Registration
Statement,  at the time it  became  effective  under the Act (but  after  giving
effect to any modifications incorporated therein pursuant to Rule 430A under the
Act) and as of the Closing Date or the Option  Closing Date, as the case may be,
contained an untrue  statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the  statements  therein
not misleading,  and (ii) the Prospectus, or any supplement thereto, on the date
it was filed pursuant to the Rules and Regulations and as of the Closing Date or
the Option Closing Date, as the case may be,  contained an untrue statement of a
material fact or omitted to state a material fact necessary in order to make the
statements  in the light of the  circumstances  under  which they are made,  not
misleading  (except  that such  counsel  need  express  no view as to  financial
statements, schedules and statistical information therein). With respect to such
statement, Ryley, Carlock & Applewhite may state that their belief is based upon
the procedures set forth therein,  but is without independent  investigation and
verification.

          (c) The  Representatives  shall  have  received  from  Piper & Marbury
     L.L.P., counsel for the Underwriters,  an opinion dated the Closing Date or
     the Option  Closing Date, as the case may be,  substantially  to the effect
     specified in subparagraphs  (ii),  (iii),  (iv), (ix) and (xi) of Paragraph
     (b) of this Section 6, and that the Company is a duly organized and validly
     existing  corporation under the laws of the State of Arizona.  In rendering
     such opinion  Piper & Marbury  L.L.P.  may rely as to all matters  governed
     other  than by the laws of the State of  Maryland  or  Federal  laws on the
     opinion of  counsel  referred  to in  paragraph  (b) of this  Section 6. In
     addition to the matters set forth above,  such opinion shall also include a
     statement  to the effect  that  nothing has come to the  attention  of such
     counsel which leads them to believe that (i) the Registration Statement, or
     any amendment  thereto,  as of the time it became  effective  under the Act
     (but after giving effect to any modifications incorporated

                                       11
<PAGE>

     therein  pursuant to Rule 430A under the Act) as of the Closing Date or the
     Option Closing Date, as the case may be, contained an untrue statement of a
     material  fact or omitted to state a material  fact  required  to be stated
     therein or necessary to make the  statements  therein not  misleading,  and
     (ii) the Prospectus,  or any supplement  thereto,  on the date it was filed
     pursuant to the Rules and  Regulations  and as of the  Closing  Date or the
     Option Closing Date, as the case may be, contained an untrue statement of a
     material  fact or omitted to state a material  fact  necessary  in order to
     make the statements in the light of the circumstances under which they were
     made, not  misleading  (except that such counsel need express no view as to
     financial  statements,   schedules  and  statistical  information  included
     therein). With respect to such statement,  Piper & Marbury L.L.P. may state
     that their belief is based upon the procedures  set forth  therein,  but is
     without independent check and verification.

          (d) The Representatives shall have received at or prior to the Closing
     Date from Piper & Marbury  L.L.P.,  a  memorandum  or summary,  in form and
     substance  satisfactory  to  the  Representatives,   with  respect  to  the
     qualification for offering and sale by the Underwriters of the Shares under
     the  State  securities  or  Blue  Sky  laws of  such  jurisdictions  as the
     Representatives may reasonably have designated to the Company.

          (e) The  Representatives  shall  have  received,  on each of the dates
     hereof,  the Closing Date or the Option Closing Date, as the case may be, a
     signed  letter  from Arthur  Andersen  LLP,  dated the Closing  Date or the
     Option  Closing Date, as the case may be, which shall confirm that they are
     independent  public  accountants  within  the  meaning  of the  Act and the
     applicable  published Rules and Regulations  thereunder and stating that in
     their opinion the financial  statements and schedules  examined by them and
     included  in the  Registration  Statement  comply  in form in all  material
     respects with the  applicable  accounting  requirements  of the Act and the
     related  published  Rules  and  Regulations;   and  containing  such  other
     statements  and  information  as is  ordinarily  included  in  accountants'
     "conform letters" to Underwriters with respect to the financial  statements
     and  certain  financial  and  statistical   information  contained  in  the
     Registration Statement and Prospectus.

          (f) The Representatives shall have received on the Closing Date or the
     Option Closing Date, as the case may be, a certificate or  certificates  of
     the  President  or the Chief  Executive  Officer  and the  Chief  Financial
     Officer of the Company to the effect  that,  as of the Closing  Date or the
     Option Closing Date, as the case may be, each of them severally  represents
     as follows:

               (i) The Registration Statement has become effective under the Act
          and no stop order  suspending the  effectiveness  of the  Registration
          Statement has been issued,  and no  proceedings  for such purpose have
          been taken or are, to his knowledge, contemplated by the Commission.

               (ii) The  representations and warranties of the Company contained
          in Section 1 hereof are true and correct as of the Closing Date or the
          Option Closing Date, as the case may be;

               (iii) All filings  required  to have been made  pursuant to Rules
          424 or 430A under the Act have been made;

               (iv) He has carefully examined the Registration Statement and the
          Prospectus  and,  in his  opinion,  as of the  effective  date  of the
          Registration  Statement,  the statements contained in the Registration
          Statement were true and correct,  and such Registration  Statement and
          Prospectus did not omit to state a material fact required to be stated
          therein  or  necessary  in order to make the  statements  therein  not
          misleading,   and  since  the  effective  date  of  the   Registration
          Statement, no event has occurred which should have been set forth in a
          supplement to or an amendment of the Prospectus  which has not been so
          set forth in such supplement or amendment; and

               (v) Since the respective  dates as of which  information is given
          in the Registration  Statement and Prospectus,  there has not been any
          material  adverse  change or any  development  involving a prospective
          material  adverse change in or affecting the  condition,  financial or
          otherwise, of the Company and its Subsidiaries taken as a whole or the
          earnings,   business,   management,    properties,   assets,   rights,
          operations,  condition  (financial  or  otherwise) or prospects of the
          Company and the Subsidiaries taken as a whole,  whether or not arising
          in the ordinary course of business.

          (g) The Company and the Selling  Shareholders  shall have furnished to
     the Representatives  such further certificates and documents confirming the
     representations and warranties,  covenants and conditions  contained herein
     and related matters as the Representatives may reasonably have requested.

                                       12

          (h) The Firm Shares, and Option Shares, if any, have been approved for
     designation upon notice of issuance on The Nasdaq National Market.

          (i) The Lockup  Agreements  described in Section 4 (a) (x) are in full
     force and effect.

     The opinions and  certificates  mentioned in this Agreement shall be deemed
to be in compliance with the provisions  hereof only if they are in all material
respects  satisfactory  to the  Representatives  and to Piper & Marbury  L.L.P.,
counsel for the Underwriters.

     If any of the conditions  hereinabove  provided for in this Section 6 shall
not have been  fulfilled when and as required by this Agreement to be fulfilled,
the  obligations  of  the  Underwriters  hereunder  may  be  terminated  by  the
Representatives  by notifying the Company and the Selling  Shareholders  of such
termination  in writing or by telegram  at or prior to the  Closing  Date or the
Option Closing Date, as the case may be.

     In such event, the Selling  Shareholders,  the Company and the Underwriters
shall not be under any  obligation to each other (except to the extent  provided
in Sections 5 and 8 hereof).

     7.  Conditions of the  Obligations of the Sellers.  The  obligations of the
Sellers to sell and deliver the portion of the Shares  required to be  delivered
as and when specified in this  Agreement are subject to the  conditions  that at
the Closing Date or the Option  Closing  Date, as the case may be, no stop order
suspending  the  effectiveness  of the  Registration  Statement  shall have been
issued and in effect or proceedings therefor initiated or threatened.

   8. Indemnification

          (a) The Company and the Selling  Shareholders,  jointly and severally,
     agree to indemnify and hold harmless each  Underwriter and each person,  if
     any, who controls any Underwriter within the meaning of the Act against any
     losses,  claims,  damages or liabilities  to which such  Underwriter or any
     such  controlling  person may become  subject  under the Act or  otherwise,
     insofar as such  losses,  claims,  damages or  liabilities  (or  actions or
     proceedings  in  respect  thereof)  arise out of or are based  upon (i) any
     untrue statement or alleged untrue statement of any material fact contained
     in the Registration Statement,  any Preliminary Prospectus,  the Prospectus
     or any  amendment or  supplement  thereto,  or (ii) the omission or alleged
     omission to state therein a material fact required to be stated  therein or
     necessary to make the statements therein not misleading, and will reimburse
     each  Underwriter and each such  controlling  person for any legal or other
     expenses reasonably incurred by such Underwriter or such controlling person
     in connection with investigating or defending any such loss, claim, damage,
     liability,  action  or  proceeding  or  in  responding  to  a  subpoena  or
     governmental inquiry related to the offering of the Shares,  whether or not
     such  Underwriters  or  controlling  person  is a party  to any  action  or
     proceeding;   provided,   however,   that  the   Company  and  the  Selling
     Shareholders  will not be liable in any such  case to the  extent  that any
     such loss,  claim,  damage or  liability  arises out of or is based upon an
     untrue  statement  or alleged  untrue  statement,  or  omission  or alleged
     omission made in the Registration  Statement,  any Preliminary  Prospectus,
     the  Prospectus,  or such amendment or supplement,  in reliance upon and in
     conformity with written information  furnished to the Company by or through
     the Representatives  specifically for use in the preparation thereof. In no
     event,  however,  shall  the  liability  of  any  Selling  Shareholder  for
     indemnification  under this Section  8(a) exceed the  proceeds  received by
     such  Selling  Shareholder  and any trusts or limited  liability  companies
     identified on Schedule II as being related to such Selling Shareholder from
     the  Underwriters  in the offering.  This  indemnity  agreement  will be in
     addition to any liability which the Company or the Selling Shareholders may
     otherwise  have,  (except  that no  party  shall  be  entitled  thereby  to
     duplicate recovery of the same item of damages).

          (b) Each Underwriter severally and not jointly will indemnify and hold
     harmless the Company, each of its directors,  each of its officers who have
     signed the  Registration  Statement,  the  Selling  Shareholders,  and each
     person, if any, who controls the Company or the Selling Shareholders within
     the meaning of the Act, against any losses,  claims, damages or liabilities
     to which the Company or any such director,  officer, Selling Shareholder or
     controlling  person may become subject under the Act or otherwise,  insofar
     as such losses,  claims,  damages or liabilities (or actions or proceedings
     in respect thereof) arise out of or are based upon (i) any untrue statement
     or  alleged  untrue  statement  of  any  material  fact  contained  in  the
     Registration Statement,  any Preliminary Prospectus,  the Prospectus or any
     amendment  or  supplement  thereto,  or (ii) the  omission  or the  alleged
     omission to state therein a material fact required to be stated  therein or
     necessary to make the statements therein not misleading in the light of the
     circumstances  under which they were made;  and will reimburse any legal or
     other  expenses  reasonably  incurred by the Company or any such  director,
     officer, Selling Shareholder or controlling

                               13

<PAGE>

     person in connection with  investigating or defending any such loss, claim,
     damage,  liability,  action or  proceeding;  provided,  however,  that each
     Underwriter  will be  liable in each  case to the  extent,  but only to the
     extent,  that such untrue statement or alleged untrue statement or omission
     or  alleged  omission  has been  made in the  Registration  Statement,  any
     Preliminary Prospectus,  the Prospectus or such amendment or supplement, in
     reliance upon and in conformity with written  information  furnished to the
     Company  by or  through  the  Representatives  specifically  for use in the
     preparation  thereof.  This indemnity  agreement will be in addition to any
     liability which such Underwriter may otherwise have,  (except that no party
     shall be  entitled  thereby  to  duplicate  recovery  of the  same  item of
     damages).

          (c) In case any proceeding (including any governmental  investigation)
     shall be instituted  involving any person in respect of which indemnity may
     be sought pursuant to this Section 8, such person (the "indemnified party")
     shall promptly  notify the person against whom such indemnity may be sought
     (the "indemnifying  party") in writing. No indemnification  provided for in
     Section  8(a) or (b) shall be available to any party who shall fail to give
     notice as provided in this Section 8(c) if the party to whom notice was not
     given was unaware of the proceeding to which such notice would have related
     and was materially  prejudiced by the failure to give such notice,  but the
     failure to give such notice  shall not relieve  the  indemnifying  party or
     parties  from any  liability  which it or they may have to the  indemnified
     party for  contribution  or otherwise  than on account of the provisions of
     Section 8(a) or (b). In case any such  proceeding  shall be brought against
     any  indemnified  party and it shall notify the  indemnifying  party of the
     commencement   thereof,   the  indemnifying  party  shall  be  entitled  to
     participate therein and, to the extent that it shall wish, jointly with any
     other indemnifying party similarly notified, to assume the defense thereof,
     with  counsel  satisfactory  to such  indemnified  party  and  shall pay as
     incurred  the  fees  and  disbursements  of such  counsel  related  to such
     proceeding.  In any such proceeding,  any indemnified  party shall have the
     right to retain its own  counsel at its own  expense.  Notwithstanding  the
     foregoing,  the  indemnifying  party  shall  pay as  incurred  the fees and
     expenses of the counsel retained by the indemnified  party in the event (i)
     the indemnifying party and the indemnified party shall have mutually agreed
     to the  retention  of such  counsel,  (ii) the  named  parties  to any such
     proceeding  (including any impleaded parties) include both the indemnifying
     party and the indemnified  party and  representation of both parties by the
     same counsel would be  inappropriate  due to actual or potential  differing
     interests between them or (iii) the indemnifying party shall have failed to
     assume in defense and employ counsel  acceptable to the indemnifying  party
     within a  reasonable  period of time after  notice of  commencement  of the
     action.  It is  understood  that  the  indemnifying  party  shall  not,  in
     connection  with  any  proceeding  or  related   proceedings  in  the  same
     jurisdiction,  be liable for the reasonable  fees and expenses of more than
     one  separate  firm for all such  indemnified  parties.  Such firm shall be
     designated in writing by you in the case of parties indemnified pursuant to
     Section 8(a) and by the Company in the case of parties indemnified pursuant
     to  Section  8(b).  The  indemnifying  party  shall not be  liable  for any
     settlement of any proceeding  effected  without its written  consent but if
     settled  with  such  consent  or if  there  be a  final  judgment  for  the
     plaintiff, the indemnifying party agrees to indemnify the indemnified party
     from and  against any loss or  liability  by reason of such  settlement  or
     judgment.  In addition,  the indemnifying party will not, without the prior
     written consent of the indemnified party settle or compromise or consent to
     the entry of any  judgment in any pending or  threatened  claim,  action or
     proceeding of which indemnification may be sought hereunder (whether or not
     any indemnified party is an actual or potential party to such claim, action
     or proceeding)  unless such  settlement,  compromise or consent includes an
     unconditional  release of each indemnified party from all liability arising
     out of such claim,  action or  proceeding,  but only to the extent any such
     liability is subject to indemnification under this Agreement.

          (d)  If  the  indemnification  provided  for  in  this  Section  8  is
     unavailable to or insufficient to hold harmless an indemnified  party under
     Section  8(a) or (b) above in respect  of any  losses,  claims,  damages or
     liabilities  (or actions or  proceedings  in respect  thereof)  referred to
     therein,  then each indemnifying  party shall contribute to the amount paid
     or payable by such  indemnified  party as a result of such losses,  claims,
     damages or liabilities  (or actions or  proceedings in respect  thereof) in
     such proportion as is appropriate to reflect the relative benefits received
     by the  Company  and  the  Selling  Shareholders  on the one  hand  and the
     Underwriters on the other from the offering of the Shares. If, however, the
     allocation provided by the immediately  preceding sentence is not permitted
     by applicable  law then each  indemnifying  party shall  contribute to such
     amount paid or payable by such  indemnified  party in such proportion as is
     appropriate  to  reflect  not  only  such  relative  benefits  but also the
     relative fault of the Company and the Selling  Shareholders on the one hand
     and the  Underwriters  on the other in  connection  with the  statements or
     omissions which resulted in such losses, claims, damages or liabilities (or

                                       14
<PAGE>

     actions or proceedings in respect  thereof),  as well as any other relevant
     equitable considerations. The relative benefits received by the Company and
     the Selling  Shareholders on the one hand and the Underwriters on the other
     shall be deemed to be in the same proportion as the total net proceeds from
     the offering (before  deducting  expenses)  received by the Company and the
     Selling   Shareholders  bear  to  the  total  underwriting   discounts  and
     commissions and compensation received by the Underwriters,  in each case as
     set forth in the table on the cover  page of the  Prospectus  and any other
     financial  benefits  received by the  Underwriters  from the offering.  The
     relative  fault shall be  determined  by reference  to, among other things,
     whether the untrue or alleged  untrue  statement of a material  fact or the
     omission  or  alleged   omission  to  state  a  material  fact  relates  to
     information  supplied by the Company or the Selling Shareholders on the one
     hand or the  Underwriters  on the other and the parties'  relative  intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement  or  omission.  

          The Company,  the Selling Shareholders and the Underwriters agree that
     it would  not be just  and  equitable  if  contributions  pursuant  to this
     Section  8(d)  were  determined  by  pro  rata  allocation   (even  if  the
     Underwriters  were treated as one entity for such  purpose) or by any other
     method  of  allocation  which  does  not  take  account  of  the  equitable
     considerations  referred to above in this Section 8(d).  The amount paid or
     payable by an indemnified party as a result of the losses,  claims, damages
     or liabilities  (or reasonable  actions or proceedings in respect  thereof)
     referred to above in this Section 8(d) shall be deemed to include any legal
     or  other  expenses  reasonably  incurred  by  such  indemnified  party  in
     connection  with  investigating  or  defending  any such  action  or claim.
     Notwithstanding  the provisions of this  subsection (d), (i) no Underwriter
     shall be required to  contribute  any amount in excess of the  underwriting
     discounts and commissions and benefits  applicable to the Shares  purchased
     by such Underwriter,  (ii) no person guilty of fraudulent misrepresentation
     (within  the  meaning of Section  11(f) of the Act)  shall be  entitled  to
     contribution  from  any  person  who was  not  guilty  of  such  fraudulent
     misrepresentation,  and (iii) no Selling  Shareholder  shall be required to
     contribute any amount in excess of the lesser of (A) that proportion of the
     total  of such  losses,  claims,  damages  or  liabilities  indemnified  or
     contributed  against  equal to the  proportion  of the  total  Shares  sold
     hereunder which is being sold by such Selling Shareholder and any trusts or
     limited liability  companies  identified on Schedule II as being related to
     such  Selling  Shareholder,  or (B) the  proceeds  received by such Selling
     Shareholder  and any trusts or limited  liability  companies  identified on
     Schedule  II  as  being  related  to  such  Selling  Shareholder  from  the
     Underwriters in the offering. The Underwriters' obligations in this Section
     8(d)  to  contribute   are  several  in  proportion  to  their   respective
     underwriting obligations and not joint.

          (e) In any  proceeding  relating to the  Registration  Statement,  any
     Preliminary  Prospectus,  the  Prospectus  or any  supplement  or amendment
     thereto,  each party  against  whom  contribution  may be sought under this
     Section  8  hereby  consents  to  the  jurisdiction  of  any  court  having
     jurisdiction over any other contributing party, agrees that process issuing
     from  such  court may be  served  upon him or it by any other  contributing
     party and consents to the service of such process and agrees that any other
     contributing  party may join him or it as an  additional  defendant  in any
     such proceeding in which such other contributing party is a party.

          (f)  The  indemnity  and  contribution  agreements  contained  in this
     Section 8 and the  representations  and warranties of the Company set forth
     in this  Agreement  shall  remain  operative  and in full force and effect,
     regardless of (i) any investigation made by or on behalf of any Underwriter
     or any person  controlling any Underwriter,  the Company,  its directors or
     offices or any persons  controlling  the Company,  (ii)  acceptance  of any
     Shares and payment  therefor  hereunder,  and (iii) any termination of this
     Agreement. A successor to any Underwriter, or to the Company, its directors
     or officers,  or any person  controlling the Company,  shall be entitled to
     the benefits of the indemnity,  contribution and  reimbursement  agreements
     contained in this Section 8.

     9. Default by  Underwriters.  If on the Closing Date or the Option  Closing
Date, as the case may be, any Underwriter shall fail to purchase and pay for the
portion of the Shares which such  Underwriter has agreed to purchase and pay for
on such date (otherwise than by reason of any default on the part of the Company
or a Selling  Shareholder),  you, as Representatives of the Underwriters,  shall
use your reasonable efforts to procure within 36 hours thereafter one or more of
the other  Underwriters,  or any others,  to  purchase  from the Company and the
Selling  Shareholders  such amounts as may be agreed upon and upon the terms set
forth herein,  the Firm Shares or Option  Shares,  as the case may be, which the
defaulting  Underwriter or  Underwriters  failed to purchase.  If during such 36
hours  you,  as  such  Representatives,  shall  not  have  procured  such  other
Underwriters,  or any others,  to purchase the Firm Shares or Option Shares,  as
the case may be, agreed to be purchased by the defaulting Underwriter or

                                       15

<PAGE>
Underwriters,  then (a) if the aggregate  number of shares with respect to which
such  default  shall  occur  does not  exceed  10% of the Firm  Shares or Option
Shares,  as the case may be, covered  hereby,  the other  Underwriters  shall be
obligated,  severally, in proportion to the respective numbers of Firm Shares or
Option  Shares,  as the  case  may be,  which  they are  obligated  to  purchase
hereunder,  to purchase  the Firm Shares or Option  Shares,  as the case may be,
which such defaulting  Underwriter or Underwriters failed to purchase, or (b) if
the aggregate number of shares of Firm Shares or Option Shares,  as the case may
be,  with  respect to which such  default  shall  occur  exceeds 10% of the Firm
Shares or Option Shares, as the case may be, covered hereby, the Company and the
Selling Shareholders or you as the Representatives of the Underwriters will have
the right, by written notice given within the next 36-hour period to the parties
to this Agreement,  to terminate this Agreement without liability on the part of
the non-defaulting Underwriters or of the Company or of the Selling Shareholders
except to the extent provided in Section 8 hereof.  In the event of a default by
any  Underwriter  or  Underwriters,  as set forth in this Section 9, the Closing
Date or Option  Closing  Date,  as the case may be,  may be  postponed  for such
period, not exceeding seven days, as you, as  Representatives,  may determine in
order  that  the  required  changes  in  the  Registration  Statement  or in the
Prospectus or in any other documents or arrangements  may be effected.  The term
"Underwriter" includes any person substituted for a defaulting Underwriter.  Any
action taken under this Section 9 shall not relieve any  defaulting  Underwriter
from  liability  in  respect  of any  default  of such  Underwriter  under  this
Agreement.

     10. Notices.  All communications  hereunder shall be in writing and, except
as  otherwise  provided  herein,  will  be  mailed,  delivered,   telecopied  or
telegraphed and confirmed as follows:  if to the Underwriters,  to Alex. Brown &
Sons  Incorporated,  135  East  Baltimore  Street,  Baltimore,  Maryland  21202,
Attention:  Robert  P.  Irwin,  Principal;  with a copy  to  Alex.  Brown & Sons

     11.  Termination.  This Agreement may be terminated by you by notice to the
Sellers as follows: 

          (a) at any time  prior to the  earlier  of (i) the time the Shares are
     released by you for sale by notice to the Underwriters,  or (ii) 11:30 A.M.
     on the first business day following the date of this Agreement;

          (b) at any time prior to the Closing Date if any of the  following has
     occurred:  (i) since the respective dates as of which  information is given
     in the  Registration  Statement and the  Prospectus,  any material  adverse
     change or any development  involving a prospective  material adverse change
     in or affecting the condition,  financial or otherwise,  of the Company and
     its Subsidiaries  taken as a whole or the earnings,  business,  management,
     properties, assets, rights, operations,  condition (financial or otherwise)
     or prospects of the Company and its Subsidiaries taken as a whole,  whether
     or not arising in the  ordinary  course of  business,  (ii) any outbreak or
     escalation of hostilities  or  declaration of war or national  emergency or
     other national or international calamity or crisis or change in economic or
     political   conditions  if  the  effect  of  such   outbreak,   escalation,
     declaration, emergency, calamity, crisis or change on the financial markets
     of  the  United  States  would,  in  your  reasonable  judgment,   make  it
     impracticable to market the Shares or to enforce  contracts for the sale of
     the Shares or, (iii)  suspension of trading in securities  generally on the
     New York Stock  Exchange or the American  Stock  Exchange or  limitation on
     prices (other than  limitations on hours or numbers of days of trading) for
     securities on either such Exchange, (iv) the enactment, publication, decree
     or other  promulgation  of any  statute,  regulation,  rule or order of any
     court or other governmental  authority which in your opinion materially and
     adversely  affects or may materially  and adversely  affect the business or
     operations  of the Company,  (v)  declaration  of a banking  moratorium  by
     United States or New York State authorities, (vi) the suspension of trading
     of the Company's  common stock by the Commission on The Nasdaq Stock Market
     or (vii) the  taking of any  action by any  governmental  body or agency in
     respect of its monetary or fiscal affairs which in your reasonable  opinion
     has a  material  adverse  effect on the  securities  markets  in the United
     States; or

     (c) as provided in Sections 6 and 9 of this Agreement.

     This Agreement also may be terminated by you, by notice to the Company,  as
to any obligation of the  Underwriters  to purchase the Option Shares,  upon the
occurrence  at any time  prior to the Option  Closing  Date of any of the events
described in  subparagraph  (b) above or as provided in Sections 6 and 9 of this
Agreement.

     12. Successors.  This Agreement has been and is made solely for the benefit
of the  Underwriters,  the  Company  and  the  Selling  Shareholders  and  their
respective successors, executors, administrators, heirs and assigns, and the 

                                       16

<PAGE>
officers,  directors and controlling  persons  referred to herein,  and no other
person will have any right or obligation  hereunder.  No purchaser of any of the
Shares from any Underwriter shall be deemed a successor or assign merely because
of such purchase.

     13.  Information  Provided  by  Underwriters.   The  Company,  the  Selling
Shareholders  and  the   Underwriters   acknowledge  and  agree  that  the  only
information  furnished or to be furnished by any  Underwriter to the Company for
inclusion  in any  Prospectus  or the  Registration  Statement  consists  of the
information  set forth in the last paragraph on the front cover page (insofar as
such information  relates to the Underwriters),  legends required by Item 502(d)
of  Regulation  S-K  under  the  Act  and  the  information  under  the  caption
"Underwriting" in the Prospectus.

     14.  Miscellaneous.  The  reimbursement,  indemnification  and contribution
agreements contained in this Agreement and the  representations,  warranties and
covenants in this Agreement shall remain in full force and effect  regardless of
(a) any  termination  of this  Agreement,  (b) any  investigation  made by or on
behalf of any Underwriter or controlling  person thereof,  or by or on behalf of
the Company or its directors or officers and (c) delivery of and payment for the
Shares under this Agreement.

     For  all  purposes  of  this  Agreement,   including  the   indemnification
provisions set forth in Section 8, the term "Selling Shareholder" shall mean not
only the applicable trust or limited  liability  company which is selling shares
of Common Stock hereunder but also shall include,  in the case of any such trust
(or  limited  liability  company) L. Randy  Knight,  Gary J. Knight and Kevin P.
Knight (in their individual capacities), as applicable.

     This Agreement may be executed in two or more  counterparts,  each of which
shall be deemed an original,  but all of which together shall constitute one and
the same instrument.

     This Agreement shall be governed by, and construed in accordance  with, the
laws of the State of Maryland.

     If the foregoing  letter is in accordance  with your  understanding  of our
agreement,  please  sign  and  return  to us  the  enclosed  duplicates  hereof,
whereupon it will become a binding agreement among the Selling Shareholders, the
Company and the several Underwriters in accordance with its terms.

                   Re:      Knight Transportation, Inc. - Registration Statement
                            on Form S-1  pertaining to One Million Eight Hundred
                            Forty Thousand  (1,840,000)  Shares of Common Stock,
                            par value $ .01 per share (the "Shares")

Ladies and Gentlemen:

                  In connection  with the  registration  of the Shares under the
Securities Act of 1933, as amended (the "Act"), by Knight Transportation,  Inc.,
an Arizona  corporation  (the  "Company"),  pursuant  to Form S-1 filed with the
Securities and Exchange Commission (the "Commission") on or about June 14, 1996,
as amended  ("Registration  Statement),  you have  requested  our  opinion  with
respect to the matters set forth below.

                  We  have  acted  as  corporate  counsel  for  the  Company  in
connection  with the matters  described  herein.  In our  capacity as  corporate
counsel to the Company,  we have reviewed and are familiar with the  proceedings
taken  and  proposed  to  be  taken  by  the  Company  in  connection  with  the
authorization,  issuance  and  sale of the  Shares  and,  for  purposes  of this
opinion,  we have assumed all such  proceedings  will be timely completed in the
manner presently  proposed.  In addition,  we have relied upon  certificates and
advice from the officers of the Company  upon which we believe we are  justified
in relying and on various  certificates  from, and documents  recorded with, the
Arizona  Corporation  Commission (the "ACC"),  including the Company's  Restated
Articles of  Incorporation  filed with the ACC on August 31, 1994.  We have also
examined  the Amended and  Restated  Bylaws of the Company  dated April 11, 1995
(the  "Bylaws")  and the  resolutions  of the Board of  Directors of the Company
adopted or effective on or before June 14, 1996, and in full force

                              ---------------------

         Section 4.1  Additional Provisions for Fixed Rate Advances.

                  (a)  Unavailability  of Deposits or Inability to Ascertain the
         Rates.  Notwithstanding any other provision of this Agreement, if prior
         to the commencement of any Interest Period,  Lender shall determine (i)
         that  United  States  dollar  deposits  in the amount of any LIBOR Rate
         Advance to be outstanding  during such Interest  Period are not readily
         available to Lender in the London interbank  market,  or (ii) by reason
         of circumstances  affecting the London interbank  market,  adequate and
         reasonable  means do not exist for  ascertaining  the LIBOR  Base Rate,
         then Lender shall  promptly give notice thereof to the Borrower and the
         obligation of Lender to create,  or effect by conversion any LIBOR Rate
         RLC Advance in such amount and for such Interest Period shall terminate
         until United States dollar deposits in such amount and for the Interest
         Period selected by the Borrower shall again be readily available in the
         market and adequate and  reasonable  means exist for  ascertaining  the
         LIBOR Base Rate.

                  (b) Increased  Costs.  (i) If, due to any  Regulatory  Change,
         there  shall be any  increase in the cost to Lender of agreeing to make
         or making,  funding or  maintaining  Fixed  Rate  Advances  (including,
         without   limitation,   any   increase   in  any   applicable   reserve
         requirement),  or of issuing or maintaining Letters of Credit, then the
         Borrower shall from time to time, upon demand by Lender,  pay to Lender
         such  amounts as Lender may  reasonably  determine  to be  necessary to
         compensate   Lender  for  any  additional  costs  which  it  reasonably
         determines are attributable to such Regulatory  Change;  (ii) if Lender
         determines  (in its  reasonable  discretion)  that,  as a result of any
         Regulatory  Change,  the amount of capital  required  or expected to be
         maintained  by Lender is  increased  by or based upon the  existence of
         Lender's commitment to lend hereunder, then, upon demand by Lender, the
         Borrower  shall  immediately  pay to Lender such  amounts as Lender may
         reasonably  determine  to be  necessary  to  compensate  Lender for any
         additional costs which it reasonably determines are attributable to the
         maintenance by Lender of capital in respect of

                                      -12-
<PAGE>
         Lender's commitment to lend hereunder; and (iii) Lender will notify the
         Borrower  of  any  Regulatory   Change  that  will  entitle  Lender  to
         compensation   pursuant   to  this   Section   3.7(b)  as  promptly  as
         practicable,  but in any event  within  90 days  after  Lender  obtains
         knowledge thereof; provided, however, that if Lender fails to give such
         notice  within 90 days after it obtains  knowledge of such a Regulatory
         Change,  Lender shall, with respect to compensation  payable in respect
         of any costs resulting from such Regulatory Change, only be entitled to
         payment  for costs  incurred  from and after the date that  Lender  has
         given  such  notice.  Lender  will  furnish to  Borrower a  certificate
         setting  forth in  reasonable  detail  the basis for the amount of each
         request by Lender  for  compensation.  Determinations  by Lender of the
         amounts  required to  compensate  Lender  shall be made on a reasonable
         basis.  Lender shall be entitled to compensation in connection with any
         Regulatory Chance only for costs actually incurred by such Lender. Upon
         receipt of notice of any such  Regulatory  Change from Under,  Borrower
         shall  have the option to prepay or  Convert  any Fixed  Rate  Advances
         adversely  affected by any  Regulatory  Change within seven (7) days of
         receipt of such notice,  without the  obligation  to pay to Lender with
         respect  to  such  prepayment  or  Conversion  any  amount  or  amounts
         otherwise payable to Lender by Borrower pursuant to Section 4.1(e).

                  (c)  Illegality.  Notwithstanding  any other provision of this
         Agreement,  if Lender shall  notify the Borrower  that as a result of a
         Regulatory Change it is unlawful for Lender, to perform its obligations
         hereunder to make LIBOR Rate Advances or to fund or maintain LIBOR Rate
         Advances  hereunder (i) the obligation of Lender to make, or to Convert
         RLC Advances into,  LIBOR Rate Advances shall be suspended until Lender
         shall notify Borrower that the circumstances causing such suspension no
         longer  exist and (ii) in the event such  Regulatory  Change  makes the
         maintenance  of LIBOR Rate Advances  hereunder  unlawful,  the Borrower
         shall   forthwith   prepay  in  full  all  LIBOR  Rate   Advances  then
         outstanding,  together with interest accrued thereon and all amounts in
         connection with such  prepayments  specified in Section 4.1(e),  unless
         the  Borrower,  within five (5)  Business  Days of notice from  Lender,
         converts all LIBOR Rate RLC Advances  then  outstanding  into  Variable
         Rate RLC Advances in accordance  with Section 3.4 with no obligation to
         pay any amount  described  in Section  4.1(e) in  connection  with such
         prepayments.

                  (d)   Discretion   of  Lender   as  to   Manner  of   Funding.
         Notwithstanding any provision of this Agreement to the contrary, Lender
         shall be entitled to fund and  maintain  its funding of all or any part
         of any Fixed Rate Advance in any manner it sees fit; provided, however,
         that for the purposes of this Agreement,  all determinations  hereunder
         shall be made as if Lender  had  actually  funded and  maintained  each
         Fixed Rate Advance  during the  Interest  Period  therefor  through the
         purchase of deposits having a maturity corresponding to the last day of
         the Interest

                                      -13-

         Period and bearing an interest  rate equal to the  applicable  Rate for

outstanding  principal  balance is less than $50,000.00,  and if the outstanding
principal  balance is equal to or more than  $50,000.00,  an amount equal to the
present value of the remaining  cash flows  discounted at the Treasury  Constant
Yield (TCY) + 100 basis points] - outstanding  principal.  The TCY is calculated
as the interpolated constant maturity Treasury rate with a maturity matching the
remaining  average 9 term of the Term Note to the Term Maturity Date.  Rate data
is obtained,  at the time of prepayment,  from the most recent  Federal  Reserve
statistical  release  H.15(519),  using data from the most  recent  week  ending
column.

the existence or form of the indebtedness treated herein, or by any performance,
or failure or waiver  thereof,  by any party of the terms hereof.  Specifically,

third  party  as  to  the  solvency  of  the  Borrower  or  of  the   commercial
practicability  of any business  enterprise  to which or for which the Loans are
made.

         Section  11.4  Notices.  All notices  required or permitted to be given

         Section 11.9  Arbitration.

                  (a) Binding Arbitration. Upon the demand of Borrower or Lender
         (collectively,  the "parties"),  whether made before the institution of
         any  judicial  proceeding  or not more than 60 days after  service of a
         complaint,  third party  complaint,  cross-claim or counterclaim or any
         answer  thereto or any  amendment to any of the above,  any Dispute (as
         defined  below) shall be resolved by binding  arbitration in accordance
         with the terms of this  arbitration  clause.  A "Dispute" shall include
         any action, dispute, claim, or controversy of any kind, whether founded
         in contract,  tort, statutory or common law, equity, or otherwise,  now
         existing or

                                      -23-
<PAGE>
         hereafter  occurring  between the parties arising out of, pertaining to
         or in  connection  with  this  Agreement  or  any  related  agreements,
         documents,  or instruments (the  "Documents").  The parties  understand
         that by this  Agreement  they have  decided  that the  Disputes  may be
         submitted to arbitration  rather than being decided through  litigation
         in court before a judge or jury and that once decided by an  arbitrator
         the claims involved cannot be brought, filed or pursued in court.

                  (b) Governing Rules.  Arbitrations  conducted pursuant to this
         Agreement, including selection of arbitrators, shall be administered by
         the American Arbitration Association  ("Administrator") pursuant to the
         Commercial   Arbitration  rules  of  the  Administrator.   Arbitrations
         conducted  pursuant  to the  terms  hereof  shall  be  governed  by the
         provisions of the Federal Arbitration Act (Title 9 of the United States
         Code), and to the extent the foregoing are inapplicable,  unenforceable
         or invalid,  the laws of the State of Arizona.  Judgment upon any award
         rendered  hereunder  may be entered in any court  having  jurisdiction;
         provided,  however, that nothing contained herein shall be deemed to be
         a waiver by any party that is a Lender of the  protections  afforded to
         it under 12 U.S.C. ss. 91 or similar governing state law. Any party who
         fails to submit to binding arbitration following a lawful demand by the
         opposing party shall bear all costs and expenses,  including reasonable
         attorney's   fees,   incurred  by  the  opposing  party  in  compelling
         arbitration of any Dispute.

                  (c) No Waiver,  Preservation of Remedies, Multiple Parties. No
         provision  of, nor the exercise of any rights under,  this  arbitration
         clause shall limit the right of any party to (1) foreclose  against any
         real or personal  property  collateral or other security,  (2) exercise
         self-help remedies  (including  repossession and set off rights) or (3)
         obtain  provisional  or ancillary  remedies such as injunctive  relief,
         sequestration, attachment, replevin, garnishment, or the appointment of
         a  receiver  from a  court  having  jurisdiction.  Such  rights  can be
         exercised at any time except to the extent such action is contrary to a
         final award or decision in any arbitration proceeding.  The institution
         and  maintenance of an action as described above shall not constitute a
         waiver of the right of any party,  including the  plaintiff,  to submit
         the Dispute to  arbitration,  nor render  inapplicable  the  compulsory
         arbitration provisions hereof. Any claim or Dispute related to exercise
         of any  self-help,  auxiliary  or other  exercise of rights  under this
         section (c) shall be a Dispute hereunder.

                  (d)   Arbitrator    Powers   and    Qualifications:    Awards.
         Arbitrator(s)  shall  resolve  all  Disputes  in  accordance  with  the
         applicable  substantive a Arbitrator(s) may make an award of attorneys'
         fees and expenses if permitted by law or the  agreement of the parties.
         All statutes of limitation applicable to any Dispute shall apply to any
         proceeding in accordance with this arbitration  clause.  Any arbitrator
         selected to act as the only  arbitrator  in a Dispute shall be required
         to be a  practicing  attorney  with not less than 10 years  practice in
         commercial law in the State of Arizona. With

                                      -24-

         respect to a Dispute in which the claims or amounts in  controversy  do
         not  exceed  five  hundred  thousand  dollars   ($500,000),   a  single
         arbitrator shall be chosen and shall resolve the Dispute.  In such case
         the arbitrator shall have authority to render an award up to but not to
         exceed five hundred thousand dollars  ($500,000)  including all damages
         of any kind  whatsoever,  costs,  fees and  expenses.  Submission  to a
         single  arbitrator  shall be a waiver of all parties' claims to recover
         more than five hundred thousand dollars ($500,000). A Dispute involving
         claims or  amounts  in  controversy  exceeding  five  hundred  thousand
         dollars  ($500,000)  shall be decided by a majority  vote of a panel of
         three arbitrators  ("Arbitration Panel"). An Arbitration Panel shall be
         composed of one  arbitrator  who would be  qualified to sit as a single
         arbitrator in a Dispute decided by one arbitrator, one who has at least
         ten years experience in commercial lending and one who has at least ten
         years experience in the trucking  industry.  Arbitrator(s)  may, in the
         exercise of their discretion,  at the written request of a party in any
         Dispute,  (1)  consolidate  in a single  proceeding  any multiple party
         claims that are substantially identical and all claims arising out of a
         single  loan  or  series  of  loans  including  claims  by  or  against
         borrower(s)  guarantors,  sureties  and  or  owners  of  collateral  if
         different from the Borrower,  and (2) administer  multiple  arbitration
         claims as class actions in accordance with Rule 23 of the Federal Rules
         of Civil Procedure. The arbitrator(s) shall be empowered to resolve any
         dispute  regarding the terms of this Agreement or the  arbitrability of
         any  Dispute  or  any  claim  that  all  or any  part  (including  this
         provision)  is void or  voidable  but shall  have no power to change or
         alter the terms of this Agreement. The award of the arbitrator(s) shall
         be in writing  and shall  specify  the  factual and legal basis for the
         award.

                  (e)  Miscellaneous.  To the maximum  extent  practicable,  the
         Administrator,  the Arbitrator(s) and the parties shall take any action
         necessary  to  require  that an  arbitration  proceeding  hereunder  be
         concluded  within  180  days of the  filing  of the  Dispute  with  the
         Administrator. The arbitrator(s) shall be empowered to impose sanctions
         for any party's failure to proceed within the times established herein.
         Arbitration  proceedings  hereunder  shall be conducted in Arizona at a
         location  determined  by the  Administrator.  In any such  proceeding a
         party shall state as a  counterclaim  any claim which arises out of the
         transaction  or  occurrence  or is in any way related to the  Documents
         which does not require the presence of a third party which could not be
         joined as a party in the proceeding. The provisions of this arbitration
         clause shall survive any termination,  amendment,  or expiration of the
         Documents  and  repayment  in full of sums owed to  Lender by  Borrower
         unless the parties  otherwise  expressly  agree in writing.  Each party
         agrees  to keep  all  Disputes  and  arbitration  proceedings  strictly
         confidential,  except for  disclosures of  information  required in the
         ordinary course of business of the parties or as required by applicable
         law or regulation.

year] ending  ___________ for Borrower as required under Section 7.5 of the Loan

condition  exists  that,  after  notice  or  passage  of time,  or  both,  would
constitute an Event of Default.

Very truly yours,

                                      -----



         THIS LEASE, made and entered into as of this 1st day of February, 1991,
by and between QUICK-FUEL,  INC., a Wisconsin corporation  ("Lessee"),  and RR-1
LIMITED PARTNERSHIP, an Illinois limited partnership ("Lessor").


                              W I T N E S S E T H:

         WHEREAS,  Lessor is the owner of certain real estate located at 3650 W.
Minnesota  St., City of  Indianapolis,  County of Marion,  State of Indiana (the
"Premises"); and

         WHEREAS,  Lessor desires to lease to Lessee and Lessee desires to lease
from Lessor a portion of the Premises.

         NOW,  THEREFORE,  Lessor and  Lessee,  in  consideration  of the mutual
agreements set forth herein, do hereby promise, covenant and agree as follows:

         1. Leased Premises.

                  1.1 Lessor hereby  leases to Lessee,  and Lessee hereby leases
from  Lessor,  that  portion of the Premises  (the  "Leased  Premises")  as more
particularly  described  on  Exhibit A attached  hereto and made a part  hereof,
which  Leased  Premises  are  necessary  for Lessee to  maintain  and operate an
automated  fueling  site for the sale of diesel and  gasoline  fuel using a card
lock fuel system (the "Fueling  Service").  Upon Lessor's  reasonable  approval,
Lessee may install such  equipment as is necessary to the  operation of Lessee's
Fueling  Service (the "Lessee's  Equipment").  Lessor further  acknowledges  and
agrees that Lessee is the sole owner of Lessee's Equipment and has all rights of
ownership  therein which  includes the right to remove such  equipment  upon the
termination of this Lease; provided,  however, that the right to remove Lessee's
Equipment  is  subject  to the terms and  conditions  of this  Lease,  including
Lessor's option to purchase Lessee's Equipment.

                  1.2 Lessor  hereby  acknowledges  and  agrees  that the Leased
Premises  will be used by Lessee in  connection  with the  operation of Lessee's
Fueling Service and Lessor hereby grants Lessee and Lessee's customers the right
of  occupancy  of and free and  unhindered  ingress  and  agress  to the  Leased
Premises and free and unhindered use of and access to Lessee's Equipment and the

will only be used by Lessee in connection with the operation of Lessee's Fueling
Service and that no other use of the Leased  Premises will be permitted  without
Lessor's consent. Lessee will not directly or indirectly,  including through the
use of vending machines, sell any other product or service.

         2. Leasehold Improvements.

                  2.1 Lessee  shall at its own cost and  expense  construct  all
improvements  reasonably  necessary to enable it to conduct the Fueling  Service
("Leasehold Improvements").  All construction drawings, plans and specifications
relating to the construction of the Leasehold Improvements shall be submitted to
and approved by Lessor, and/or its architects or contractors, prior to beginning
construction  of  the  Leasehold  Improvements,  which  approval  shall  not  be
unreasonably  withheld.  The Leasehold  Improvements  shall be  constructed in a
workmanlike  manner and in compliance with all applicable laws and  regulations,
including but not limited to applicable zoning and other land use laws.

                  2.2 Lessee shall  instruct its  contractors  to perform  their
work on the Leased Premises,  and in and about the Premises generally,  with due
care and regard for the  improvements  being  constructed  by Lessor  ("Lessor's
Improvements"),  minimizing as much as possible the interference  with Lessor or
its employees,  agents,  officers and invitees (including Lessor's  contractors,
subcontractors and others providing materials ro services in connection with the
construction of Lessor's Improvements).

                  2.3  Lessee  shall  keep the  Leased  Premises  free  from any
mechanic's liens created by any act or failure to act by Lessee,  its employees,
agents, officers and invitees. In the event any mechanic's lien is filed against
the  Leased  Premises  by  virtue  of any act or  failure  to act on the part of
Lessee,  Lessee shall promptly have the same removed or shall post a bond in the
amount of one hundred twenty-five percent (125%) of such lien or in an amount as
determined  by a Court in order to bond over such lien.  In the event Lessee doe
snot do so,  Lessor shall have the right to do so and shall also have the right,
but no  obligation,  to pay the amount of such lien to cause its release and any
amount so paid shall be recoverable from Lessee. All mechanic's liens created by
Lessee's acts shall attach only to Lessee's interests in the Leased Premises and
not to any other  interest  with  respect to either  the  Premises  or  Lessor's
Improvements.

                  2.4  All  signs  and  advertising  to be  used  by  Lessee  in
connection  with the Fueling Service at the Leased Premises shall be approved by
Lessor in advance of its use.  Lessor,  in its sole  discretion,  may disapprove
such signs or advertising if it determines it to be incompatible  with the "Road
Ready" image or signs.

                  3.1 The term of this Lease  shall  commence on the date hereof

option, may either purchase Lessee's Equipment and/or the Leasehold Improvements

Equipment  and/or the Leasehold  Improvements  to be removed.  Unless  otherwise
agreed by the  parties,  Lessor's  purchase  or  Lessee's  removal  of  Lessee's

calculation of the Monthly Rental for the month.  Lessor, at its expense,  shall
have the  right to  conduct  such  examinations  and  audits  as are  reasonably
required  to verify the  calculation  of the  Monthly  Rental and Lessee  hereby
acknowledges  and  agrees  to  grant  Lessor,  or  its   representatives,   such
examination or audit.  Such examination or audit shall be conducted so as to not
disturb daily business and all information obtained will be deemed confidential.

         5.  Warranty.  Lessee  warrants  that as of the date  hereof,  Lessee's
Equipment  is in good  condition  and,  to the best of  Lessee's  knowledge,  it

                                    additional  named  insured and loss payee as
                                    its interest may appear.

                           (c)      Certificates  evidencing such policies shall
                                    be   furnished  to  Lessor  by  Lessee  upon
                                    request by Lessor.

                  8.2  Lessor  shall,  during  the  term of this  Lease  and any
extension thereof,  at its own expense,  carry  comprehensive  general liability
insurance and fire and extended  coverage  insurance in amounts no less than the
level of insurance  required to be maintained by Lessee under  paragraph  8.1(a)
above.  The  policies  shall  cover  accident  or damage  in or on the  Premises
(including the Leased  Premises) and any associated  parking area,  entranceways
and other common areas of the
                                       -4-

Premises.  Such  policies  shall name Lessee as an  additional  insured and loss
payee to the  extent of  insuring  Lessee  from any  damages  or  claims  caused
directly or indirectly  from the operation of Lessor's  business or from acts or
omissions of the Lessor  and/or its  employees,  agents,  officers and invitees.
Certificates  evidencing  such  policies  shall be furnished to Lessee by Lessor
upon request by Lessee.

                  8.3 Each  party  hereto  shall  indemnify  and hold the  other
harmless from and against any and all claims, actions, damages,  liabilities and
expenses  (including  but not limited to attorney  fees) in connection  with (i)
loss of life,  personal injury and/or damage to property  arising from or out of
any occurrence  in/upon or at the Leased  Premises caused directly or indirectly
by such party or its  employees,  agents,  officers  and  invitees;  or (ii) any
breach by such party of its obligations  under this Lease.  In addition,  Lessee
shall  indemnify  and hold Lessor  harmless from and against any and all claims,
actions,  damages,  liabilities and expenses  incurred by Lessor which relate to
spillage,  seepage  or  other  loss of  petroleum  products  onto  the  Premises
(including the Leased  Premises) or any other  environmental  condition  arising
from the conduct of the  Fueling  Service  during the term hereof  except to the
extent that any such loss, damage,  claim,  action,  liability or expense (i) is
the  result of the  negligent  acts or  omissions  of  Lessor or its  employees,
agents,  officers  and  invitees,  or  (ii)  relates  to any  of  the  foregoing
conditions existing upon the commencement of the term hereof (including, without
limitation,  surface  contamination)  which  in  each  case  shall  be the  sole
responsibility  and  obligation of Lessor and Lessee shall be fully  indemnified
with respect thereto.

         9. Destruction or Condemnation of the Leased Premises.

                  9.1  Should  the  Leased  Premises,  or any part  thereof,  be
damaged or destroyed by fire, storm, explosion or other casualty, whether or not
of the same class or kind  enumerated,  Lessor shall repair the Leased Premises,
or any part thereof, at Lessor's expense and Lessee shall be responsible for the
repair and restoration of Lessee's Equipment and the Leasehold Improvements.  In
addition,  should such damage or destruction,  or repairs  resulting  therefrom,
require  Lessee to discontinue  operations of its Fueling  Service at the Leased
Premises, rental shall immediately abate from the date of such closing until the
Leased  Premises  are again fit for  operation of a Furling  Service;  provided,
however,  that the rental  shall not abate if such  damage or  destruction  is a
result of the acts or  omissions of Lessee or its  employees  or agents.  Should
more than one-third (1/3) of the Leased Premises be destroyed or damaged, Lessee
shall have the  option,  exercisable  by giving  Lessor  written  notice of such
exercise within thirty (30) days after such damage or destruction,  to terminate
this Lease.

                  9.2 Should  one-tenth (1/10) or more of the Leased Premises be
taken by eminent domain by any public authority,  purchased by such authority in
lieu of  condemnation,  or should  there be a change in any law,  regulation  or
order,  including any judicial decision,  action or order, which makes operation
of the Fueling Service  impracticable,  Lessee may elect to terminate this Lease
by written  notice within thirty (30) days of such taking or the effective  date
or the date of issuance (whichever is later) of such decision,  action, order or
legislation. In the event Lessee does
                                       -5-
<PAGE>
not elect to terminate the Lease or if less than one-tenth  (1/10) of the Leased
Premises is so taken,  this Lease shall continue in effect;  provided,  however,
that the rental due hereunder shall be subject to renegotiation if the taking of
any portion of the Leased Premises  materially  impacts upon Lessee's ability to
provide  the  Fueling  Service.  In the  event of any such  taking,  the  entire
compensation awarded shall belong to Lessor, except for any amounts specifically
applicable to damages incurred by Lessee, and except for any amount representing
prepaid rent.

         10. Quiet Enjoyment. Lessee shall peacefully and quietly have, hold and
enjoy the Leased Premises for the term of this Lease, free from lat or hindrance
by Lessor or any party  claiming  by or  through  Lessor,  for so long as Lessee
faithfully  performs  all the duties and  obligations  to be performed by Lessee
under this  Lease.  Further,  Lessee  shall have  reasonable  access to Lessor's
Improvements  to maintain and repair Lessee's  computer  equipment which will be
located in an area selected by Lessor.

         11. Repairs and Maintenance.

                  11.1 Lessee shall, at all times during the term of this Lease,
make all necessary repairs to the Leased Premises and the Leasehold Improvements
located thereon at its expense;  provided,  however,  that such repairs have not
been caused by the neglect,  misuse or  carelessness of Lessor or its employees,
agents,  officers or invitees.  Lessee shall be  responsible  for  repairing and
maintaining  Lessee's  Equipment  at all times  during  the term of this  Lease;
provided, however, that such repairs and maintenance have not been caused by the
neglect, misuse or carelessness of Lessor or its employees,  agents, officers or
invitees, in which event Lessor shall bear responsibility for the same.

                  11.2 Lessee agrees to make, at Lessee's  expense,  all repairs
to the Premises (including the Leased Premises) caused by the neglect, misuse or
carelessness of Lessee and its employees, agents, officers or invitees.

                  11.3 Lessor shall  provide to Lessee at no  additional  charge
daily trash and litter pick-up on the Leased Premises; provided, however, Lessee
agrees to keep the Leased Premises in a clean,  tenantable condition,  and shall
not permit any garbage,  rubbish,  refuse, or dirt to accumulate in or about the
Leased Premises.

                  11.4  Lessor  shall  provide  to  Lessee at  reasonable  times
general site maintenance for the Leased Premises,  including but not limited to,
snow removal,  landscape  maintenance,  maintenance  of the paved areas and site
lighting.

         12. Trade Fixtures. If all rents due herein are paid in full and Lessee
is not otherwise in default hereunder, all trade fixtures installed by Lessee or
by its permitted subtenants or assigns in connection with the business conducted
by it or them on the Leased  Premises  may be removed by it or them during or at
the expiration of this Lease or of any removal thereof. Notwithstanding the 
                                      -6-
<PAGE>
foregoing,  all trade fixtures installed by Lessee shall be so removed by Lessee
at Lessor's  request upon the  expiration of this Lease.  Any damages  caused by
removal of such trade fixtures shall be repaired by Lessee at Lessee's sole cost
and expense.

         13.  Mortgage  Subordination.  Lessee  agrees  that upon the request of
Lessor  it will  subordinate  this  Lease to the lien of any  present  or future
mortgagee  upon the Leased  Premises,  or any part  thereof,  provided  that the
mortgagee  agrees in writing that said  mortgagee will not terminate this Lease,
or disturb the Lessee's  possession of the Leased  Premises or do anything which
would adversely affect the right of Lessee hereunder so long as Lessee is not in
default hereunder.


         14. Transfer by Lessor.  In the event of a sale or conveyance by Lessor
of the Leased Premises, the same shall operate to release Lessor from any future
liability upon any of the covenants or conditions herein contained,  and in such
event Lessee  agrees to look solely to the  responsibility  of the  successor in
interest of Lessor in and to this Lease. Lessee has option of agreeing to attorn
to the  purchaser or grantee,  who in such case shall be obligated on this Lease
so  long  as it is  the  owner  of  Lessor's  interest  in and  to  this  Lease.
Alternatively,  upon any sale or  conveyance  by  Lessor,  Lessee  may  elect to
terminate  this Lease within thirty (30) days of Lessee's  notice of the sale or
conveyance.  In the event of  termination,  Lessor's  purchaser or grantee shall
elect to exercise one of the options set forth in Section 3.2 above.

         15. Default.

                  15.1 This Lease may,  upon five (5) days  written  notice,  be
terminated,  notwithstanding  the terms contained in Paragraph 3 above, upon the
occurrence of any of the following:

                                            within   ten  (10)  days   after  it
                                            becomes due,  except with respect to
                                            any portion of the rent which may be
                                            reasonably be in dispute; or

                                    (ii)    fail to perform or observe any other
                                            term,  covenant or agreement  herein
                                            to be  performed or observed and any
                                            such failure remains  unremedied for
                                            a  period  of ten  (10)  days  after
                                            receipt  of  notice  from  Lessor of
                                            such failure.

                           (b)      At the option of either  party,  exercisable

                                    (i)     the Leased Premises shall be used by
                                            Lessor  for any  purpose  other than

                                    AGREEMENT

This Agreement is entered into as of the 31 day of October, 1995, by and between
QUICK-FUEL,   INC.,  a  Wisconsin  corporation  ("Lessee"),   and  RR-1  LIMITED
PARTNERSHIP, an Illinois Limited Partnership ("Lessor").

                                    Recitals

Lessor and  Lessee are  parties  to four (4)  leases  dated:  February  1, 1991,
(Bridgeview  site);  February 1, 1991  (South  Holland  site);  February 1, 1991
(Indianapolis  site);  and March 1, 1991 (Elk Grove Village  site)(collectively,
the "Leases"),  pursuant to which Lessee sells fuel at four  locations  owned by
Lessor. Under paragraph 4 of each of the Leases, Lessee pays to Lessor a monthly
rental equal to $ .0275 time the number of gallons of fuel sold by Lessee at the
site. The parties  desire to amend  paragraph 4 of each of the Leases to provide
for a quarterly rental schedule based, in part, on the combined quarterly volume
of fuel sold by Lessee at the four locations.

NOW,  THEREFORE,  in  consideration  of the premises and other good and valuable
consideration, the parties agree as follows:

1. In satisfaction of Lessee's payment of rent under the four Leases  referenced
above, Lessee shall pay the Lessor, by check or other  consideration  acceptable
to Lessor, a quarterly rental calculated as follows:  $ .0275 times # of gallons
of fuel sold during the quarter to  purchasers  utilizing  Lessee's  proprietary
fuel  charge  card,  plus $ .0175  times # of  gallons  of fuel sold  during the
quarter to purchasers utilizing a third party fuel charge card. In addition,  in
any calender quarter where Lessee fails to sell at any location at least 100,000
gallons of fuel to purchasers  utilizing Lessee's  proprietary fuel charge card,
Lessee shall pay to Lessor an amount equal to $ .0275 times (% to equal  100,000
gallons minus # of gallons actually sold at such location). The quarterly rental
shall be payable on the thirtieth  (30th) day of the month  following the end of
the calender quarter.

2. This Agreement shall be deemed to amend paragraph 4 of the four Leases to the
extent  that the  provisions  herein are  inconsistent  with the  provisions  of
paragraph 4. In all other respects the terms and conditions of the Leases remain
unchanged and in full force and effect.

IN WITNESS  WHEREOF,  the parting  have  executed  this  Agreement by their duly
authorized representatives effective as of the date first set forth above.
