NOTE 4. ACQUISITION

The Company acquired the assets of a Mississippi-based  truckload carrier during
the quarter ended June 30, 2000. The Company's consolidated financial statements
include the  operations of this  subsidiary  from the date of  acquisition.  The
acquired  assets and assumed  liabilities  were recorded at their estimated fair
values at the acquisition  date in accordance with Accounting  Principles  Board
("APB") Opinion No. 16. In conjunction with the acquisition,  the Company issued
343,182  shares of common  stock from its  treasury  shares.  These  shares were
valued at fair  market  value less a discount  due to the  restricted  nature of
these shares.  Adjustments  to the purchase price  allocations,  if any, are not
expected to have a material impact on the  accompanying  consolidated  financial
statements.  Terms of the purchase  agreement set forth conditions upon which an
earn-out  adjustment to the purchase price based upon earnings may be necessary.
This  earn-out  adjustment  may be in  the  form  of  additional  shares  of the
Company's common stock and/or cash.

The aggregate purchase price of the acquisition  consisted of the following,  in
thousands:

NOTE 5. SEGMENT INFORMATION

The Company has seven operating segments; however, it has determined that it has
one  reportable  segment.  Six of the  segments  are  managed  based on  similar
economic characteristics.  Each of the six regional operating divisions provides
short to  medium-haul  truckload  carrier  services of general  commodities to a
similar  class  of  customers.  In  addition,  each  division  exhibits  similar
financial  performance,  including average revenue per mile and operating ratio.
The remaining  segment is not reported  because it does not meet the materiality
thresholds  in SFAS No.  131.  As a result of the  foregoing,  the  Company  has
determined that it is appropriate to aggregate its operating  divisions into one
reportable  segment  consistent with the guidance in SFAS No. 131.  Accordingly,
the Company has not presented  separate  financial  information  for each of its
operating divisions as the Company's  consolidated  financial statements present
its one reportable segment.

NOTE 6. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June, 1998 the Financial  Accounting Standards Board ("FASB") issued SFAS No.
133,  Accounting  for  Derivative  Instruments  and  Hedging  Activities.   This
statement   establishes   accounting  and  reporting  standards  for  derivative
instruments,  including derivative instruments embedded in other contracts,  and
for hedging  activities.  In June 1999, the FASB issued SFAS No. 137, Accounting
for Derivative  Instruments  and Hedging  Activities - Deferral of the Effective
Date of SFAS No.  133.  This  statement  was  adopted by the  Company  effective
January 1, 2001. The adoption of this  statement did not have a material  impact
on the Company's results of operations or financial position.

In July 2001, the FASB issued SFAS No. 141, Business Combinations,  and SFAS No.
142, Goodwill and Other Intangible Assets.  SFAS No. 141 requires the use of the
purchase method of accounting and prohibits the use of the  pooling-of-interests
method of accounting for business  combinations  initiated  after June 30, 2001.
This  statement  also requires that the Company  recognize  acquired  intangible
assets  apart from  goodwill if the  acquired  intangible  assets  meet  certain
criteria.  SFAS No. 142 requires,  among other things,  that companies no longer
amortize  goodwill,  but instead test goodwill for impairment at least annually.
In addition, SFAS No. 142 requires that the Company identify reporting units for
purposes of assessing  potential  future  impairments of goodwill,  reassess the
useful  lives  of  other  existing  recognized   intangible  assets,  and  cease
amortization of intangible  assets with an indefinite useful life. An intangible
asset  with an  indefinite  useful  life  should be  tested  for  impairment  in
accordance  with the guidance in SFAS No. 142. This  statement is required to be
applied in fiscal years  beginning  after  December 15, 2001 to all goodwill and
other intangible assets recognized at that date, regardless of when those assets
were  initially  recognized.  SFAS No. 142  requires  the  Company to complete a
transitional  goodwill  impairment  test  within  six  months  from  the date of
adoption and reassess the useful  lives of other  intangible  assets  within the
first  interim  quarter  after  adoption.  At present,  the Company is currently
assessing but has not yet  determined  the complete  impact the adoption of SFAS
No.  141 and SFAS No. 142 will have on its  financial  position  and  results of
operations.

NOTE 7. COMMITMENTS AND CONTINGENCIES

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

NOTE 8. RECAPITALIZATION AND STOCK SPLIT

On May 9, 2001,  the Board of  Directors  approved a three for two stock  split,
effected in the form of a 50 percent stock dividend. The stock split occurred on
June 1, 2001, to  stockholders  of record as of the close of business on May 18,
2001. The number of common shares  authorized,  issued and outstanding,  and all
per share amounts, have been adjusted to reflect the stock split for all periods
presented.

RESULTS OF OPERATIONS

The Company's revenue, before fuel surcharge,  for the six months ended June 30,
2001,  increased  by 18.4% to $112.7  million  from $95.2  million over the same
period in 2000. For the three months ended June 30, 2001,  revenue,  before fuel
surcharge,  increased by 13.6% to $58.7 million from $51.7 million over the same
period in 2000.

The increase in revenue,  before fuel surcharge,  resulted from expansion of the
Company's customer base and increased volume from existing  customers.  This was
facilitated  by the continued  expansion of the Company's  fleet,  including the
addition of approximately 225 tractors in the April 19, 2000 acquisition of John
Fayard Fast  Freight,  Inc.  The  Company's  fleet  increased  by 15.4% to 1,797
tractors  (including 209 owned by independent  contractors) as of June 30, 2001,
from 1,557 tractors (including 243 owned by independent  contractors) as of June
30, 2000.

Salaries,  wages and benefits increased as a percentage of revenue,  before fuel
surcharge,  to 33.6% for the six months ended June 30, 2001,  from 33.1% for the
same period in 2000.  This  increase was primarily the result of the increase in
the ratio of Company drivers to independent  contractors.  At June 30, 2001, 88%
of the Company's fleet was operated by Company drivers,  compared to 84% at June
30, 2000. For the three months ended June 30, 2001, salaries, wages and benefits
decreased as a percentage of revenue, before fuel surcharge, to 33.3% from 33.9%
for the same  period in 2000.  This  decrease  was the  result of the  Company's
efforts to improve the ratio of  non-driving  employees to tractors by utilizing
technology to increase efficiencies. The Company's insurance program for medical
claims which involves self- insurance with risk retention levels, was higher for
the 2001 period compared to the 2000 period. Claims in excess of these retention
levels are  covered by  insurance,  which  management  considers  adequate.  The
Company records the cost of medical insurance coverage, along with the uninsured
portion,  to salaries,  wages and benefits  expense.  For Company  drivers,  the
Company records accruals for worker's  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.

                                       10

Fuel  expense,  net of fuel  surcharge,  remained  consistent as a percentage of
revenue,  before fuel surcharge, at 12.5% for the six months ended June 30, 2001
and for the same period in 2000. For the three months ended June 30, 2001,  fuel
expense as a percentage of revenue,  before fuel  surcharge,  increased to 12.7%
from 12.6% for the same period in 2000.  This  increase was primarily the result
of recent higher fuel costs per gallon,  as well as the increase in the ratio of
Company vehicles to independent  contractors.  Independent contractors pay their
own fuel costs.

Operations and maintenance expense increased as a percentage of revenue,  before
fuel surcharge, to 5.6% for the six months ended June 30, 2001 from 5.4% for the
same period in 2000.  This  increase  was  primarily  due to the increase in the
ratio of Company vehicles to independent contractors. For the three months ended
June 30,  2001 and for the same  period  in  2000,  operations  and  maintenance
expense as a percentage of revenue,  before fuel surcharge,  remained consistent
at 5.4%.

Insurance and claims expense  increased as a percentage of revenue,  before fuel
surcharge,  to 3.8% for the six months  ended June 30,  2001,  from 2.1% for the
same period in 2000.  For the three months ended June 30,  2001,  insurance  and
claims expense increased as a percentage of revenue,  before fuel surcharge,  to
3.7% from 2.4% for the same period in 2000. These variations  reflect the effect
of the increases in insurance rates and self-insurance retention levels incurred
during the 2001 periods compared to the same periods in 2000.

Operating taxes and licenses  decreased as a percentage of revenue,  before fuel
surcharge,  to 3.0% for the six months  ended June 30,  2001,  from 3.8% for the
same period in 2000. For the three months ended June 30, 2001,  operating  taxes
and licenses as a percentage  of revenue,  before fuel  surcharge,  decreased to
2.9% compared to 3.7% for the same period in 2000.  These  decreases were due to
overall improved  management of the tractor and trailer licensing in the various
states the Company operates in.

Communications  expense as a percentage of revenue,  before fuel surcharge,  for
both the six months and three  months  ended June 30, 2001  remained  relatively
consistent with the same periods in 2000, at less than 1.0% of revenue.

Depreciation  and amortization  expense as a percentage of revenue,  before fuel
surcharge,  decreased to 8.6% for the six month period ended June 30, 2001, from
9.4% for the same  period in 2000.  For the three  months  ended June 30,  2001,
depreciation and amortization decreased as a percentage of revenue,  before fuel
surcharge,  to 8.2% from 9.3% for the same period in 2000.  These decreases were
due to the initiation of a leasing program as described below.

Lease  Expense -  Revenue  Equipment  as  percentage  of  revenue,  before  fuel
surcharge, was 3.5% for the six months ended June 30, 2001, compared to 0.9% for
the same period in 2000.  For the three months ended June 30, 2001 Lease Expense
- - Revenue Equipment as a percentage of revenue, before fuel surcharge,  was 3.6%
compared to 1.6% for the same period in 2000.  These  increases  were due to the
initiation of a leasing program to obtain additional revenue equipment,  as well
as the increase in the ratio of the company vehicles to independent contractors.

Purchased  transportation  decreased  as a  percentage  of revenue,  before fuel
surcharge,  to 10.7% for the six months ended June 30, 2001,  from 13.7% for the
same  period in 2000.  For the  three  months  ended  June 30,  2001,  purchased
transportation as a percentage of revenue,  before fuel surcharge,  decreased to
10.5% from 12.2% for the same period in 2000.  These  decreases  were due to the
decrease in the ratio of independent contractors to Company drivers to 12% as of
June 30, 2001, from 16% as of June 30, 2000.  Independent  contractors pay their
own expenses, including fuel, and are compensated at a fixed rate per mile.

                                       11

Miscellaneous  operating  expenses,  as a  percentage  of  revenue,  before fuel
surcharge,  were  slightly  higher for the three and six months  ending June 30,
2001,  compared to the same periods in 2000.  These increases were primarily due
to decreased  utilization of the Company's  fleet and increased  travel expenses
during the 2001 periods.

As a result of the above  factors,  the  Company's  operating  ratio  (operating
expenses,  net of fuel  surcharge,  as a  percentage  of  revenue,  before  fuel
surcharge) for the six months ended June 30, 2001, increased to 85.0% from 84.4%
for the same period in 2000. The Company's  operating ratio remained  consistent
at 84.5% for the three months  ended June 30,  2001,  and for the same period in
2000.

For both the six  months and three  months  ended June 30,  2001,  net  interest
expense decreased as a percentage of revenue, before fuel surcharge, compared to
the same  periods  in 2000.  This  decrease  was  primarily  the  result  of the
Company's ability to reduce its average  outstanding debt by approximately $19.6
million at June 30,  2001  compared  to June 30,  2000.  Recent  trends of lower
interest  rates on the  Company's  line of credit  borrowings  and the equipment
leasing program discussed above, have also contributed to this decrease.

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

As a result of the preceding  changes,  the Company's net income as a percentage
of revenue,  before fuel  surcharge,  was 8.2% for the six months ended June 30,
2001,  compared to 8.9% for the same period in 2000.  For the three months ended
June 30, 2001, net income as a percentage of revenue, before fuel surcharge, was
8.6%, compared to 8.9% for the same period in 2000.

LIQUIDITY AND CAPITAL RESOURCES

The growth of the Company's  business has required a  significant  investment in
new revenue equipment.  The Company's primary source of liquidity has been funds
provided  by  operations  and the  Company's  lines of credit  with its  primary
lender.  Net cash  provided by  operating  activities  was  approximately  $19.8
million  for the first six months of 2001,  compared  to $13.7  million  for the
corresponding period in 2000.

Capital  expenditures for the purchase of revenue  equipment,  net of trade-ins,
office equipment and leasehold  improvements totaled $10.4 million for the first
six months of 2001 compared to $20.5 million for the same period in 2000.

Net cash used in financing  activities  was  approximately  $9.6 million for the
first six months of 2001,  compared to net cash used in financing  activities of
$0.4 million for the same period in 2000. Net cash used in financing  activities
during  the  first  six  months  of 2001 was  primarily  used  for pay  downs of
long-term debt and the Company's line of credit.

The Company  maintains a line of credit totaling $50 million with its lender and
uses this  line to  finance  the  acquisition  of  revenue  equipment  and other
corporate  uses to the extent the Company's  need for capital is not provided by
funds from operations. The Company is obligated to comply with certain financial
covenants under its line of credit.  The rate of interest on borrowings  against
the line of credit will vary  depending  upon the interest rate election made by
the Company,  based upon either the London Interbank Offered Rate ("Libor") plus
an adjustment factor, or the prime rate. The average interest rate

                                       12

for the three months ended June 30, 2001,  was 5.7%.  Borrowings  under the line
amounted to $30.2 million at June 30, 2001. The line expires in July 2003.

The Company,  through its subsidiaries,  has entered into lease agreements under
which it leased  revenue  equipment.  The  Company  has  guaranteed  all revenue
equipment  leases.  The total amount financed under these  agreements as of June
30, 2001, was  $45,556,409,  with effective  interest rates ranging from 5.2% to
8.2%, with $8,921,122 due in the next 12 months.

Management  believes  the Company  has  adequate  liquidity  to meet its current
needs. 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.  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.

FACTORS THAT MAY AFFECT FUTURE RESULTS

The Company's  future  results may be affected by a number of factors over which
the Company has little or no control.  Fuel prices,  insurance and claims costs,
liability  claims,  interest  rates,  the  availability  of  qualified  drivers,
fluctuations  in the resale  value of revenue  equipment,  economic and customer
business cycles and shipping demands are economic factors over which the Company
has little or no control.  Significant  increases or rapid  fluctuations in fuel
prices, interest rates or insurance costs or liability claims, to the extent not
offset by increases in freight rates, and the resale value of revenue  equipment
could  reduce the  Company's  profitability.  Weakness in the  general  economy,
including a weakness in consumer demand for goods and services,  could adversely
affect  the  Company's  customers  and the  Company's  growth and  revenues,  if
customers reduce their demand for transportation services.  Weakness in customer
demand for the Company's  services or in the general rate  environment  may also
restrain the Company's ability to increase rates or obtain fuel surcharges.

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 contractual opportunities. Difficulty in attracting or retaining qualified
drivers,  including independent contractors,  or a downturn in customer business
cycles or  shipping  demands  also could have a material  adverse  effect on the
growth and  profitability of the Company.  If a shortage of drivers should occur
in the future, or if the Company were unable to continue to attract and contract
with independent contractors, the Company could be required to adjust its driver
compensation package,  which could adversely affect the Company's  profitability
if not offset by a corresponding  increase in rates. The Company has experienced
the effects of fuel and driver  wage  increases  and is seeking to recover  such
charges  through rate increases and a fuel  surcharge.  By increasing  rates and
imposing a fuel surcharge, the Company could lose customers who are unwilling to
pay the increases.

The Company's  growth has been made possible through the addition of new revenue
equipment.  Difficulty  in  financing or obtaining  new revenue  equipment  (for
example, delivery delays from manufacturers or the unavailability of independent
contractors)  could restrict future growth.  There is currently an excess supply
of  used  revenue  equipment  on the  market.  Although  the  Company  has  made
arrangements  to fix the  repurchase  or trade price of most of its used revenue
equipment it periodically sells or exchanges with its vendors, if the surplus of
used  revenue  equipment  continues  and the resale  price of revenue  equipment
continues to decline, the

                                       13

Company may be forced to retain its revenue equipment  longer,  with a resulting
increase in operating  expenses for maintenance and repairs.  The current supply
of used tractors and trailers on the market may  adversely  affect the Company's
ability to obtain favorable terms on the tractors and trailers the Company sells
or exchanges for new revenue equipment.

The  Company  periodically  makes  investments  in  companies  that may  provide
strategic  support for its  transportation  business.  The Company has  invested
approximately $6 million in such companies as of June 30, 2001. Current economic
conditions in the transportation industry have adversely affected demand for the
products and services such companies provide. The Company understands that these
businesses have modified their business plans to address  adverse  conditions in
the  transportation  industry.  Although the Company believes its investments in
these  companies  are  sound and may  ultimately  work to the  advantage  of the
Company and may fulfill their respective  purposes,  economic  conditions in the
transportation  industry, and the conditions of economy in general, have made it
more difficult for each of these  companies to sell their goods and services and
to  execute  and  achieve  their  original  business  objectives.  There  are no
assurances  that the Company's  investment in each of these entities will not be
adversely affected if adverse economic conditions in the transportation industry
continue,  including  the  deterioration  of the  financial  condition  of  many
carriers within the transportation industry, who purchase the goods and services
offered by these companies.

Current  economic  conditions  in the  transportation  industry  have  adversely
affected demand for Terion's products, particularly its two-way digital wireless
communications  product.  These same  economic  conditions  also have  adversely
affected  Concentrek's  ability to market its  logistics  services.  The Company
understands  that both Terion and Concentrek  have modified their business plans
to address  adverse  conditions  in the  transportation  industry.  Although the
Company  believes its  investments  in both Terion and  Concentrek are sound and
will  ultimately  work to the  advantage of the Company and will  fulfill  their
respective purposes, economic conditions in the transportation industry, and the
conditions of economy in general,  have made it more difficult for each of these
companies to execute and achieve their original business  objectives,  and there
are no assurances  that the Company's  investment in each of these entities will
not be adversely  affected if adverse economic  conditions in the transportation
industry  continue,  including the  deterioration of the financial  condition of
many carriers within the transportation  industry, who purchase the products and
services offered by Terion and Concentrek.

The Company has experienced  significant and rapid growth in revenue 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 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.

Currently,  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 more significant portion of its revenues from markets in the Midwest,
South  Central,  Southeastern  and Southern  regions and on the East Coast,  its
growth and  profitability  could be  materially  adversely  affected  by general
economic declines or natural disasters in those markets.

The Company has established  regional  operations in Katy, Texas;  Indianapolis,
Indiana; Charlotte, North Carolina; Gulfport, Mississippi; Salt Lake City, Utah;
and Kansas  City,  Missouri in order to serve  markets in these  regions.  These
regional  operations  require the commitment of additional revenue equipment and
personnel, as well as management resources,  for future development.  Should the
growth in the Company's regional operations throughout the United States slow or
stagnate,  the results of Company  operations could be adversely  affected.  The
Company may  encounter  operating  conditions  in these new markets  that differ
substantially from those previously experienced in its western United States

                                       14

markets.  There  can be no  assurance  that  the  Company's  regional  operating
strategy,   as  employed  in  the  western  United  States,  can  be  duplicated
successfully  in the other  areas of the United  States or that it will not take
longer than expected or require a more  substantial  financial  commitment  than
anticipated.

SEASONALITY

In the transportation industry, results of operations frequently show a seasonal
pattern.  Seasonal variations may result from weather or from customer's reduced
shipments after the busy winter holiday season.

To date, the Company's revenues have not shown any significant seasonal pattern.
Because the Company  has  operated  primarily  in  Arizona,  California  and the
western United States, winter weather conditions have not adversely affected the
Company's business.  The expansion of the Company's operations into the Midwest,
on the East  Coast,  the  Southeast  and Gulf Coast  regions,  could  expose the
Company to greater operating variances due to seasonal weather in these regions.
Recent  shortage of energy  issues in  California  and  elsewhere in the Western
United  States,  could  result in an  adverse  effect on the  operations  of the
Company and demand for the Company's services should these shortages continue or
increase.  This  risk may  exist in the  other  regions  in  which  the  Company
operates, depending upon changes in the energy industry.

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. In late 1999, the Company began to experience increases in fuel
costs, as a result of conditions in the petroleum industry. The Company has also
recently  experienced  some wage increases for drivers.  Increases in fuel costs
and driver  compensation are expected to continue during 2001 and may affect the
Company's  operating income,  unless the Company is able to pass those increased
costs to customers through rate increases or fuel surcharges. The Company has an
aggressive  program to obtain rate increases and fuel  surcharges from customers
in order to cover increased costs due to these increases in fuel prices,  driver
compensation  and other expenses and has been  successful in  implementing  some
fuel  surcharges.   Competitive  conditions  in  the  transportation   industry,
including lower demand for  transportation  services,  could limit the Company's
ability to continue to obtain rate increases or fuel surcharges.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company is exposed to market risk changes in interest  rate on debt and from
changes in commodity prices.

     INTEREST RATE RISK

The  Company is subject to interest  rate risk to the extent it borrows  against
its line of credit or incurs debt in the acquisition of revenue  equipment.  The
Company attempts to manage its interest rate risk by managing the amount of debt
the  Company  carries.  The  Company  has  entered  into an  interest  rate swap
agreement with its primary  lender to protect it against  interest rate risk. In
the opinion of management, an increase in short-term interest rates could have a
material adverse effect on the Company's financial

                                       15

condition  if the  Company's  debt  levels  increase  and if the  interest  rate
increases  are not offset by freight rate  increases or other items.  Management
does not  foresee or expect in the near  future any  significant  changes in the
Company's  exposure  to interest  rate  fluctuation  or in how that  exposure is
managed by the Company. The Company has not issued corporate debt instruments.

     COMMODITY PRICE RISK

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

For the  three-month  period  ended June 30,  2001,  fuel  expense,  net of fuel
surcharge,  represented 15.1% of the Company's operating  expenses,  net of fuel
surcharge,  compared  to 14.9% for the same  period  ending in 2000.  In August,
2000, the Company entered into an agreement to obtain price protection to reduce
a portion  of the  Company's  exposure  to fuel price  fluctuations.  Under that
arrangement,  the Company was obligated to purchase  certain  minimum volumes of
diesel fuel for the period beginning October 1, 2000, through March 31, 2001, at
a guaranteed price per gallon. If during the 48 month period following March 31,
2001, the price of the heating oil on the New York  Mercantile  Exchange ("NY MX
HO") falls below $.58 per gallon, the Company is obligated to pay, for a maximum
of twelve  different  months selected by the contract holder during the 48-month
period,  the  difference  between $.58 per gallon and the NY MX HO average price
for the minimum volume commitment

                          PART II -- OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The  Company  is a party to  ordinary,  routine  litigation  and  administrative
proceedings  incidental to its business.  These  proceedings  primarily  involve
personnel matters,  including Equal Employment  Opportunity  Commission ("EEOC")
claims  and  claims for  personal  injury or  property  damage  incurred  in the
transportation of freight.  The Company maintains insurance to cover liabilities
arising from the transportation of freight for amounts in excess of self-insured
retentions.  It  is  the  Company's  policy  to  comply  with  applicable  equal
employment  opportunity laws and the Company  periodically  reviews its policies
and practices for equal employment opportunity compliance.
