                                     PART I

ITEM 1.  BUSINESS.

        P.A.M. Transportation Services, Inc. (the "Company"), operating through
its wholly-owned subsidiaries, is an irregular route, common and contract motor
carrier authorized to transport general commodities throughout the continental
United States and the Canadian provinces of Ontario and Quebec, pursuant to
operating authorities granted by the former Interstate Commerce Commission
("ICC"), various state regulatory agencies and Canadian regulatory agencies.
Under its operating authorities, the Company may transport all types of freight
(except household goods, commodities in bulk and certain explosives) intrastate
within any state, and from any point in the continental United States, Ontario
or Quebec to any other point in the continental United States or in Ontario or
Quebec over any route selected by the Company. The Company transports dry
freight commodities ("freight") in 48-foot and 53-foot long, high cube
conventional and specialized freight vans ("trailers"). The freight consists
primarily of automotive parts, consumer goods, such as general retail store
merchandise and products from the manufacturing sector, such as heating and air
conditioning units, and industrial glass. All freight is transported as
truckload quantities.

        The Company is a holding company organized under the laws of the State
of Delaware in June 1986 and conducts its operations through its wholly-owned
subsidiaries, P.A.M. Transport, Inc. ("P.A.M. Transport"), P.A.M. Special
Services, Inc., T.T.X., Inc., P.A.M. Dedicated Services, Inc., P.A.M. Logistics
Services, Inc., Choctaw Express, Inc., Choctaw Brokerage, Inc. and Allen Freight
Services, Inc. The Company's operating authorities are held by P.A.M. Transport,
P.A.M. Dedicated Services, Inc., Choctaw Express, Inc., Choctaw Brokerage, Inc.
and Allen Freight Services, Inc. Although not organized until June 1986, the
Company is, for financial accounting purposes, the successor to P.A.M.
Transport, which was organized under the laws of the State of Arkansas in 1980.
Unless the context otherwise requires, all references to the Company in this
Annual Report on Form 10-K include P.A.M. Transportation Services, Inc. and its
subsidiaries. At December 31, 1997, the Company operated a transport fleet
consisting of 975 over-the-road tractors ("tractors") and 2,678 trailers.

        The Company is headquartered and maintains its primary terminal,
maintenance facilities and corporate and administrative offices in Tontitown in
the northwest corner of Arkansas, a major center for the trucking industry and
where the support services (including warranty repair services) of most major
tractor and trailer equipment manufacturers are readily available.

MARKETING/MAJOR CUSTOMERS

        The Company's marketing emphasis is directed to that segment of the
truckload market which is generally service-sensitive, as opposed to being
solely price competitive. Since 1990, the Company has diversified its marketing
efforts to gain access to non-traditional freight traffic, including
international (Mexico and Canada), domestic regional short-haul, dedicated fleet
services and intermodal transportation. The Company also participates in various
"core carrier" partnerships with its larger customers. The Company estimates
that approximately 60% of its deliveries to customers are made on a JIT ("just
in time") basis, whereby products and raw materials are scheduled for delivery
as they are needed on the retail customer's shelves or in the manufacturing
customer's production line. Such requirements place a premium on the freight
carrier's delivery performance and reliability. With respect to these JIT
deliveries, approximately 50% require the use of two-man driver teams to meet
the customer's schedule. The need for this service is a product of modern
manufacturing and assembly methods which are designed to drastically decrease
inventory levels and handling costs.

        The Company's marketing efforts are conducted by seven outside sales
persons domiciled within the Company's major markets. Field personnel are
supervised from Company headquarters, emphasizing an even flow of freight
traffic (balance between originations and destinations in a given geographical
area) and minimization of movement of empty equipment.

        During 1997, the Company's five largest customers, for which the Company
provides carrier services covering a number of geographic locations, accounted
for approximately 50% of total revenues. General Motors Corporation accounted
for approximately 25% of 1997 revenues and Packard Electric accounted for
approximately 12% of 1997 revenues. A total loss of General Motors or Packard
Electric business, however unlikely, would have an adverse impact on the
Company's operations, at least over the short term.

        The Company also provides transportation services to other manufacturers
who are suppliers for automobile manufacturers including General Motors. As a
result, concentration of the Company's business within the automobile industry
is greater than the concentration in a single customer. Of the Company's
revenues for 1997 which were attributable to its top ten customers,
approximately 41% were derived from transportation services provided to the
automobile industry.

        The Company is no longer required to file tariffs with the Interstate
Commerce Commission ("ICC") or any successor agency. See "Regulation."

OPERATIONS

        The Company maintains 24-hour dispatch offices at its headquarters, as
well as its offices in Oklahoma City, Oklahoma, Jacksonville, Florida and
Warren, Ohio, with a toll free WATS line to facilitate communications with both
customers and drivers. The location, status and contact assignment of all of the
Company's equipment are available on an up-to-date basis through the Company's
computer system, which permits the Company to better meet delivery schedules,
respond to customer inquiries and match equipment with the next available load.

        In early 1996, the Company began installing Qualcomm Omnitracs(TM)
display units in its tractors. The Omnitracs system is a satellite-based global
positioning and communications system that allows fleet managers to communicate
directly with drivers. Drivers can provide location status and updates directly
to


                                       3

<PAGE>   4

the customer's computer, saving telephone usage cost, lost productivity, and
inconvenience. The Omnitracs system provides customer service with accurate
estimated time of arrival information which optimizes load selection and service
levels to the Company's customers. At the end of 1997, substantially all of the
Company's tractors were equipped with these units and full implementation is
expected in early 1998.

        The Company communicates through electronic data interchange with many
of its customers, providing live status reports of freight shipments and arrival
time information. This system provides the Company's customers flexibility and
convenience by allowing the customer to tender freight electronically.

        The Company has contractual arrangements with some customers to move
freight in dedicated lanes within the United States. A majority of this freight
is moved on a round-trip basis, and due to the volume involved, the Company has
agreed to dedicate equipment and personnel to handle this part of its business.
The Company has found that dedicated service promotes increased utilization of
equipment and greater driver satisfaction due to the greater regularity of the
routes and schedules, which allows the drivers to be at home more often. There
exists a large volume of dedicated-type business throughout the continental
United States. The Company has enjoyed considerable success in entering this
market, and is aggressively seeking to expand its share of the dedicated
services market.

INTERMODAL SERVICE

        The Company entered the intermodal transportation business in 1992, and
has contractual arrangements with Consolidated Rail Corporation ("Conrail"),
Norfolk Southern, the Atchison, Topeka and Santa Fe Railway Company ("Santa
Fe"), Burlington Northern, Union Pacific, Illinois Central, and CSX Intermodal
("CSX"). Intermodal service provides customers with an alternative to highway
long-hauls. Management expects to take advantage of opportunities to expand this
business and views the intermodal market as a mechanism to realize non-asset
based revenue growth.

OVER-THE-ROAD EQUIPMENT

        The Company operated a fleet of 975 tractors and 2,678 trailers at
December 31, 1997. All of the trailers and all except 94 tractors are owned or
leased by the Company. The trailer fleet is made up of 863 48' by 102" dry vans
and 1,815 53' by 102" dry vans. In 1993, the Company began its trailer fleet
conversion to air ride equipment and the Company intends to purchase only air
ride trailers in the future. The Company also has certain specialized drop-frame
trailers. The tractors that are not Company owned are leased from
owner/operators on a per mile basis.

        At the end of the respective years, the average age of the Company's
tractors was 1.26 in 1995, 1.85 in 1996, and 1.94 in 1997. The average age of
the Company's trailer fleet was 2.34, 2.60 and 2.85 at the end of 1995, 1996 and
1997, respectively.

        During 1997, the Company purchased 242 new tractors and 127 new trailers
and disposed of 160 tractors and 162 trailers. During 1998, the Company expects
to purchase 495 new tractors and 700 new trailers while continuing to sell or
trade older equipment.

MAINTENANCE

        The Company has a strictly enforced comprehensive preventive maintenance
program for the tractors and trailers it operates. Inspections and various
levels of repair and preventive maintenance are performed at set mileage
intervals on both tractors and trailers. Although a significant portion of
maintenance is performed at the Company's maintenance facility in Tontitown,
Arkansas, the Company's subsidiaries have additional maintenance facilities in
Warren, Ohio; Springfield, Missouri; Dallas, Laredo and El Paso, Texas; Oklahoma
City, Oklahoma; and Columbia, Mississippi. These facilities enhance the
Company's preventive and routine maintenance operations and are strategically
located on major transportation routes where a majority of the Company's freight
originates and terminates. A maintenance and safety inspection is performed on
all vehicles each time they return to a terminal. The Company's primary
maintenance facilities consist of thirteen mechanical repair bays, four bodyshop
bays and three safety and maintenance inspection bays. The Company believes that
its current maintenance facilities will be adequate to accommodate its fleet for
the foreseeable future.

        The Company's tractors carry full warranty coverages of at least 100,000
miles. Extended warranties are negotiated with the manufacturer and major
component manufacturer (i.e., engine, transmission, differential) for up to
1,000,000 miles. Trailers are also warranted by the manufacturer and major
component manufacturer for up to five years.

        Manufacturers of tractors are required to certify that new tractors meet
federal emission standards and the Company receives such certifications on each
new tractor it acquires. Certain governmental regulations require the Company to
adhere to a fuel and oil spillage prevention plan and to comply with regulations
concerning the discharge and disposal of waste oil. The Company believes it is
in compliance with applicable waste disposal and emission regulations. The
Company also maintains insurance to cover clean up expense in the event of a
spill.

DRIVERS

        At December 31, 1997, the Company utilized 1,175 drivers in its
operations. All drivers are recruited, screened, drug tested and trained and are
subject to the control and supervision of the Company's operations and safety
departments. The Company's driver training program stresses the importance of
safety and reliable, on-time delivery. Drivers are required to report to their
dispatchers daily and at the earliest possible moment when any condition en
route occurs which might delay their scheduled delivery time.

        The Company has established relationships with recruiting and training
schools in Indiana, Missouri, and Arkansas to enhance its ability to secure the
services of qualified drivers. The Company agrees to pay a student's costs for
attending the training school so long as the student fulfills a commitment to
work for the Company for at least twelve months. Drivers who fail to complete
their 12 month commitment are required to reimburse all or a portion of the
Company's costs in training the driver, depending upon the date of termination
of employment.

        The Company's drivers are selected only after strict application
screening and drug testing. Before being permitted to operate a vehicle for the
Company, drivers must undergo classroom instruction on Company policies and
procedures, safety techniques and proper operation of equipment and then must
pass both written and road tests. Instruction in defensive driving and safety
techniques continues after hiring, with the Company holding seminars at its
terminals in Tontitown, Arkansas, Oklahoma City, Oklahoma,




                                       5
<PAGE>   6

Jacksonville, Florida, Warren, Ohio, and Columbia, Mississippi. The Company
currently employs approximately 38 persons on a full-time basis in its driver
recruiting, training and safety instruction programs.

        The Company's drivers are compensated on the basis of miles driven,
loading and unloading, extra stop pay and layovers in transit. Drivers can earn
bonuses by recruiting other qualified drivers who are employed by the Company
and both cash and non-cash prizes are awarded for consecutive periods of safe,
accident-free driving.

        Intense competition in the trucking industry for qualified drivers over
the last several years, along with difficulties and added expense in recruiting
and retaining qualified drivers, has had a negative impact on the industry. The
Company's operations have also been impacted and from time to time the Company
has experienced under-utilization and increased expenses due to a shortage of
qualified drivers. Management places the highest of priorities on the
recruitment and retention of an adequate supply of qualified drivers.

EMPLOYEES

        At December 31, 1997, the Company employed 1,446 persons, of which 1,175
are drivers, 69 are maintenance personnel, 80 are employed in operations, 29 are
employed in marketing, 38 are employed in safety and personnel, and 55 are
employed in general administration and accounting. Of the total number of
employees, 166 of the Company's employees are salaried, and the remainder are
employed on an hourly or mileage basis. The Company also has 94 owner/operators
under contract who are compensated on a per mile basis. None of these employees
are represented by a collective bargaining unit and the Company believes that
its employee relations are good.

REGULATION

        The Company is a common and contract motor carrier that is regulated by
certain state and Canadian regulatory agencies. Prior to January 1, 1996, the
Company was also regulated by the ICC. The ICC governed such activities as the
authority to engage in motor carrier operations, rates and charges, accounting
systems, certain mergers, consolidations, acquisitions and periodic financial
reporting. On January 1, 1996, however, the ICC Termination Act of 1995 (the
"Termination Act") was enacted, terminating the ICC and substantially
deregulating the rail and motor carrier industries.

        The Termination Act substantially revises the Motor Carrier Act of 1980,
eliminating numerous unnecessary provisions and streamlining many of the ICC's
functions regarding the regulation of the motor carrier industry. The majority
of the remaining ICC functions are transferred to the Department of
Transportation ("DOT"), with limited responsibilities transferred to a newly
formed Surface Transportation Board. Some of the ICC functions that have been
eliminated include: tariff filings, except for non-contiguous domestic trade;
rate regulation, except for non-contiguous domestic trade and individual
household goods movements; federal grants of operating authority; price
regulation and tariff filing requirements for office and exhibit moves; the
possibility of future undercharge claims; restrictions on intermodal ownership;
review of motor carrier mergers; and state regulation of transportation
intermediaries. In addition, registration and insurance filings under the Motor
Carrier Act are streamlined into a single federal registration and insurance
system to eliminate duplicative and burdensome filing requirements. Exemption
authority to permit administrative deregulation has also been substantially
broadened, with restrictions remaining on only cargo loss and damage, insurance,
safety fitness and antitrust immunity.


                                       6

<PAGE>   7

        Prior to the enactment of the Termination Act, most of the ICC's
authority to oversee the commercial operation of the motor carrier industry had
already been transferred to the DOT. The primary remaining functions which are
transferred to the DOT by the Termination Act are motor carrier registration and
the setting and maintenance of minimum levels of liability insurance. In
addition, the maintenance of nationwide motor carrier industry commercial rules
(such as leasing rules, uniform cargo loss and damage rules, rules for shipper
payment, and perfecting security interests) are transferred to the DOT.

        Currently, the ICC and the DOT operate separate registration systems.
The ICC requires that interstate, for hire carriers receive a license (operating
authority) with the standards for granting of authority limited to a showing of
safety and fitness and insurance coverage at a specified level. The DOT
registration system extends to all carriers, including private and exempt
carriers not regulated by the ICC. DOT assigns each carrier an identification
number. Carriers are not required to show proof of insurance at the time of DOT
registration, nor is any fee currently charged. The Termination Act continues
the two registration systems for a period of twenty-four months, during which
time the Secretary of Transportation shall conduct a rule-making and implement
changes to consolidate these two registration systems into one system. The new
system will serve as a clearing house and depository of information on and
identification of all domestic and foreign motor carriers, brokers, freight
forwarders and others required to register. The DOT will utilize the information
in overseeing safety fitness and compliance with required levels of insurance.
Registrations will be renewed periodically and the on-line system will be
available to state authorities and the public.

        The Termination Act also continues antitrust immunity granted by the ICC
but contains reforms intended to prevent any potential market abuses.

        On January 1, 1995, federal legislation went into effect eliminating
intrastate regulation of motor carrier operations. This action allows the
Company to better compete for intrastate business, possibly reducing empty
miles, and should result in more comprehensive service to the Company's existing
customers.

        Motor carrier operations are also subject to safety requirements
prescribed by the United States Department of Transportation governing
interstate operation. Such matters as weight and dimensions of equipment are
also subject to federal and state regulations.

        The Company believes that it is in compliance in all material respects
with applicable regulatory requirements relating to its trucking business and
operates with a satisfactory rating from the United States Department of
Transportation.

COMPETITION

        The trucking industry is highly competitive. The Company competes
primarily with other irregular route long-haul truckload carriers, with private
carriage conducted by its existing and potential customers, and, to a lesser
extent, with the railroads. Increased competition has resulted from deregulation
of the trucking industry and has generally exerted downward pressure on prices.
The Company competes on the basis of its quality of service and delivery
performance as well as price. Many of the other irregular route long-haul
truckload carriers have substantially greater financial resources, own more
equipment or carry a larger total volume of freight than the Company.

ITEM 2.  PROPERTIES.

        The Company's executive offices and primary terminal facilities are
located in Tontitown, Arkansas. The Company's facilities are located on
approximately 45 acres and consist of 79,193 square feet of office space and
maintenance and storage facilities. The Company's facilities in Tontitown are
owned by the Company.

        The Company's subsidiaries also lease terminal facilities in
Jacksonville, Florida; Warren, Ohio; Springfield, Missouri; Laredo, El Paso, 
and Dallas, Texas; Memphis, Tennessee; and Oklahoma City, Oklahoma; the 
terminal facilities in Columbia, Mississippi are owned. These facilities are 
leased primarily on a month-to-month basis, and provide on-the-road maintenance
and trailer drop and relay stations. The Company's subsidiaries also lease an 
aggregate of 25 other locations as trailer drop and relay stations only.

        The Company has access to trailer drop and relay stations in various
locations across the country. Certain of these facilities are leased by the
Company on a month-to-month basis from an affiliate of its majority shareholder.

RESULTS OF OPERATIONS

1997 COMPARED TO 1996

        For the year ended December 31, 1997, revenues increased 12.6% to $127
million as compared to $113.0 million for the year ended December 31, 1996. The
Company's utilization (revenue per tractor per work day) increased .37% from
$537 in 1996 to $539 in 1997.


                                       13

<PAGE>   14



        The Company's operating ratio improved from 91.5% in 1996 to 89.3% in
1997.

        Salaries, wages and benefits decreased from 46.4% of revenues in 1996 to
45.3% in 1997. The major factor for the decrease was a 1.8% decrease in the
amounts paid to fleet owners of Allen Freight Services, Inc. ("AFS"). This
decrease was partially offset, however, by an increase of 0.6% in amounts paid
to AFS company drivers who replaced AFS fleet owners.

        Interest expense decreased $714,507 in 1997 when compared to 1996,
primarily as a result of the Company reducing its long term debt and its
borrowings under its line of credit during the fourth quarter of 1996. This
reduction was accomplished by using $4.6 million in proceeds received by the
Company in connection with the exercise of stock purchase warrants by the
Company's majority shareholder.

        The Company's effective tax rate decreased from 39.3% in 1996 to 38.2%
in 1997 as a result of discontinuing the practice of reimbursing nondeductible
per diem expenses to AFS company drivers. The Company's effective tax rate
reflects the statutory federal tax rate and the average tax rate of the states
in which the Company conducts business.

        At December 31, 1997, the Company's deferred tax assets were $6.4
million and deferred tax liabilities were $15.7 million. In assessing the need
for a valuation allowance against deferred tax assets at December 31, 1997,
management considered the following factors: 1) the Company has recorded $9.3
million in deferred tax liabilities for future taxable temporary differences
(primarily depreciation related) which will result in additional taxable income
in future periods; 2) the Company's recent operating results have produced a
total of more than $23.7 million of pretax accounting income for 1997, 1996 and
1995 and net operating loss carryovers have offset all taxable income (total of
$4.1 million) in these years; 3) the Company has various alternatives, such as
equipment leasing to utilize net operating losses, which might otherwise expire;
and 4) the Company's carryover periods for its deferred tax assets are
extensive, with expiration beginning in 2003 for net operating losses and 1999
for investment credits.

1996 COMPARED TO 1995

        For the year ended December 31, 1996, revenues increased 23.4% to $113.0
million as compared to $91.6 million for the year ended December 31, 1995. The
main factor for the increase in revenues was an increase in average tractors
from 658 in 1995 to 843 in 1996, of which 162 were added in connection with the
acquisition of AFS. AFS produced revenues of $15.0 million from the acquisition
date to December 31, 1996.

        The Company's operating ratio was 91.5% of revenues in 1996 compared to
87.5% in 1995.

        Salaries, wages and benefits increased from 43.7% of revenues in 1995 to
46.4% in 1996. The major factor for the increase was a 2.6% increase in expense
attributable to wages paid to AFS fleet owners, which are higher than wages paid
to Company drivers.

        Operating supplies and expenses increased from 18.3% of revenues in 1995
to 19.3% of revenues in 1996, reflecting increased fuel costs for 1996.

        Interest expense increased approximately $616,000 in 1996 when compared
to 1995, primarily as a result of borrowings associated with new equipment
purchases and an increased line of credit balance


                                       14

<PAGE>   15

throughout the year.

        The Company's effective tax rate increased from 38% in 1995 to 39.3% in
1996, as a result of AFS' practice of paying per diem expenses to its drivers, a
portion of which is a nondeductible permanent difference in the calculation of
income tax expense. Per diems are no longer paid to AFS drivers effective July
1, 1996.

LIQUIDITY AND CAPITAL RESOURCES

        During 1997, the Company generated $25.0 million in cash from operating
activities. The ratio of current assets to current liabilities was 1.0 at the
end of 1997, compared to 1.0 and 1.1 at the end of 1996 and 1995, respectively.

        Investing activities used $16.5 million in cash in 1997 compared to
$16.8 million and $22.1 million in 1996 and 1995, respectively. The cash used in
all three years related primarily to the purchase of revenue equipment used in
the Company's operations.

        Financing activities used $8.0 million in cash in 1997 primarily to pay
off long-term debt and pay down line of credit borrowings.

        The Company's principal subsidiary, P.A.M. Transport, Inc., has a $15.0
million secured bank line of credit subject to borrowing limitations. The line
of credit includes a provision that allows the Company to finance equipment at a
reduced interest rate of LIBOR plus 1.75% (currently 7.47%). The maximum amount
of equipment that may be financed under this equipment provision is $7.5 million
with the remaining $7.5 million representing a general "working capital" line of
credit at an interest rate of LIBOR plus 2.15% (currently 7.87%). Outstanding
advances on this line of credit were approximately $6.7 million at December 31,
1997, including $1.5 million in letters of credit. The Company's borrowing
limitation at December 31, 1997 was $4.8 million. This line of credit is
guaranteed by the Company and matures May 31, 1999. The line of credit agreement
contains restrictive covenants which require the Company to maintain a net worth
of $12.5 million and a debt service coverage ratio of not less than 1.0 to 1.0.
The line of credit agreement also includes restrictions on dividend payments and
certain corporate acts such as mergers and consolidations. At December 31, 1997,
the Company was in compliance with all such covenants.

        In addition to cash flow from operations, the Company uses its existing
line of credit on an interim basis to finance capital expenditures and repay
long-term debt. Although longer-term obligations, such as installment notes
(generally three and four year terms at fixed rates) are typically entered into
for the


                                       15

<PAGE>   16

purchase of revenue equipment; the Company purchased such equipment during 1997
using its existing line of credit. The cost of this equipment was approximately
$5.7 million. Two subsidiaries of the Company, P.A.M. Transport and P.A.M.
Dedicated Services, Inc., entered into installment obligations during 1997 for
the purchase of replacement revenue equipment which totaled approximately $10.9
million and $1.7 million, respectively, payable in 36 and 48 monthly
installments, respectively, at interest rates ranging from 7.50% to 7.60%. The
Company's weighted average interest rates on all borrowings were 7.69%, 7.67%
and 7.9% for 1997, 1996 and 1995, respectively.

        During 1997, the Company sold or traded revenue equipment for
approximately $4.6 million. The Company plans to replace 300 trailers and 355
tractors, and to add 140 additional new tractors and 400 additional new trailers
during 1998, which would result in additional debt of approximately $41.2
million. Management expects that the Company's existing working capital and its
available line of credit will be sufficient to meet the Company's capital
commitments as of December 31, 1997, to repay indebtedness coming due in the
current year, and to fund its operating needs during fiscal 1998.

INSURANCE

        With respect to cargo loss, collision and auto liability, P.A.M.
Transport, P.A.M. Dedicated Services, Inc., and Choctaw Express, Inc. are
covered under the same insurance policy. The policy's auto liability and
collision coverage are subject to a $2,500 deductible per occurrence while the
cargo loss coverage has a $1,000 deductible. With respect to AFS, its auto
liability coverage is not subject to a deductible while the collision deductible
for tractors and trailers are $2,500 and $500, respectively, per occurrence.
AFS's cargo loss coverage is subject to a deductible of $5,000 per occurrence.
The Company maintains a reserve for estimated losses for claims incurred, and
maintains a reserve for claims incurred but not reported (based on the Company's
historical experience). As of July 1, 1994, the Company became self-insured for
workers' compensation, with excess coverage maintained for claims exceeding
$250,000 in Arkansas, Oklahoma, Ohio, Mississippi and Florida. Prior to July 1,
1994, the Company maintained an insurance policy for worker's compensation with
a deductible of $350,000 per occurrence. The Company has reserved for estimated
losses to pay such claims as incurred. Additionally, a reserve has been
estimated for those claims incurred but not reported. The Company has not
experienced any adverse trends involving differences in claims experienced
versus claims estimates for workers' compensation reserves. The Company
contracts with a third-party licensed associate of risk management and a
certified Hazard Control Manager to develop its workers' compensation reserves
using the Company's historical data of past injuries. Letters of credit in the
amounts of $300,000, $200,000, $250,000, and $500,000 are held by a bank as
security for workers' compensation claims in Arkansas, Oklahoma, Mississippi,
and Florida, respectively, and letters of credit in the amounts of $100,000 and
$150,000 are held by a bank for auto liability claims.

SEASONALITY

        The Company's revenues do not exhibit a seasonal pattern, due primarily
to its varied customer mix. Operating expenses are generally somewhat higher in
the winter months, primarily due to decreased fuel efficiency and increased
maintenance costs in cold weather.



                                       16

<PAGE>   17


ENVIRONMENTAL

        The Company has no outstanding inquiries with any federal or state
environmental agency at December 31, 1997.

INFLATION

        Inflation has an impact on most of the Company's operating costs.
Recently, the effect of inflation has been minimal.

        Competition for drivers has increased in recent years, leading to
increased labor costs. While increases in fuel and driver costs affect the
Company's operating costs, the effects of such increases are not greater for the
Company than for other trucking concerns.

YEAR 2000

        In the next two years, many companies may face a potentially serious
information systems problem because their computer software applications and
operational programs may not properly recognize calendar dates beginning in the
year 2000. This problem could force computers to either shut down or provide
incorrect data or information. The Company began the process of identifying the
changes required to its computer programs and hardware in early 1997. Software
upgrades designed to correct the year 2000 problem are scheduled to be
implemented in mid-1998. The Company believes that it will timely meet its year
2000 compliance requirements, and does not presently anticipate the cost of
these software and hardware changes to have a material adverse impact on its
business, financial condition, or results of operations. However, there can be 
no assurance that unforeseen difficulties or costs will not arise.

                   Notes to Consolidated Financial Statements
                                December 31, 1997


1.  ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS AND CONSOLIDATION

P.A.M. Transportation Services, Inc. (the "Company"), through its subsidiaries,
operates as a truckload motor carrier.

The consolidated financial statements include the accounts of the Company and
its subsidiaries. All significant intercompany accounts and transactions have
been eliminated.

Majority ownership of the Company is held by an affiliate of another
transportation company, with whom the Company has certain business
relationships. (See Note 8.)

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.

TIRE PURCHASES

Tires purchased with revenue equipment are capitalized as a cost of the related
equipment. Replacement tires are included in other current assets and are
amortized over a 24-month period. Amounts paid for the recapping of tires are
expensed when incurred.

EXCESS OF COST OVER NET ASSETS ACQUIRED

The excess of cost over net assets acquired, or goodwill, is being amortized on
a straight-line basis over 25 years. The carrying value of goodwill will be
reviewed if the facts and circumstances suggest that it may be impaired. If this
review indicates that goodwill will not be recoverable, as determined based on
undiscounted cash flows acquired over the remaining amortization period, the
Company's carrying value of the goodwill would be reduced by the estimated
shortfall of cash flows. No reduction of goodwill was required as of December
31, 1997.

CLAIMS LIABILITIES

With respect to cargo loss, collision and auto liability, the Company maintains
the following insurance coverage and deductibles: P.A.M. Transport, Inc., P.A.M.
Dedicated Services, Inc., and Choctaw Express, Inc. are covered under the same
insurance policy issued by St. Paul Insurance Company. The auto liability and
collision coverages are subject to a $2,500 deductible per occurrence while the
cargo loss coverage has a $1,000 deductible. Allen Freight Services, Inc., is
insured by Great West Insurance Company. The auto liability

coverage is not subject to a deductible while the collision deductible for
tractors and trailers are $2,500 and $500, respectively, per occurrence. The
cargo loss coverage is subject to a deductible of $5,000 per occurrence. The
Company maintains a reserve for estimated losses for claims incurred and
maintains a reserve for claims incurred but not reported (based on the Company's
historical experience). The Company is self-insured for workers' compensation,
with excess coverage maintained for claims exceeding $250,000 in Arkansas,
Oklahoma, Ohio, Mississippi and Florida. The Company has reserved for estimated
losses to pay such claims as incurred. Additionally, a reserve has been
estimated for those claims incurred but not reported. The Company has not
experienced any adverse trends involving differences in claims experienced
versus claims estimates for workers' compensation reserves. The Company
contracts a third-party licensed associate of risk management and a certified
Hazard Control Manager to develop its workers' compensation reserves using the
Company's historical data of past injuries. Letters of credit in the amounts of
$300,000, $200,000, $250,000, and $500,000 are held by a bank as security for
workers' compensation claims in Arkansas, Oklahoma, Mississippi, and Florida,
respectively, and letters of credit in the amounts of $100,000 and $150,000 are
held by a bank for auto liability claims.

REVENUE RECOGNITION POLICY

The Company recognizes revenue based upon relative transit time in each
reporting period with expenses recognized as incurred.

PROPERTY AND EQUIPMENT

Property and equipment is recorded at cost. For financial reporting purposes,
the cost of such property is depreciated principally by the straight-line
method. For tax reporting purposes, accelerated depreciation or applicable cost
recovery methods are used. Gains and losses are reflected in the year of
disposal. The following is a table reflecting estimated ranges of asset lives by
major class of depreciable assets:

1.  ACCOUNTING POLICIES (continued)

EQUIPMENT HELD FOR SALE

Equipment held for sale consists of revenue equipment no longer in service, that
is expected to be sold within the next year. This equipment is recorded at its
estimated net realizable value.

INCOME TAXES

The Company applies the provision of Statement of Financial Accounting Standards
No. 109, Accounting for Income Taxes ("SFAS No. 109"). SFAS No. 109 requires
recognition of deferred tax liabilities and assets for expected future
consequences of events that have been included in a company's financial
statements or tax return. Under this method, deferred tax liabilities and assets
are determined based on the difference between the financial statements and the
tax basis of assets and liabilities using enacted tax rates.

BUSINESS SEGMENT AND CONCENTRATIONS OF CREDIT RISK

The Company operates in one business segment, motor carrier operations. The
Company provides transportation services to customers throughout the United
States and portions of Canada. The Company performs ongoing credit evaluations
and generally does not require collateral. The Company maintains reserves for
potential credit losses and such losses have been within management's
expectations. At December 31, 1997, one customer accounted for 25% of the
consolidated trade accounts receivable balance. At December 31, 1996, one
customer accounted for 16% of the consolidated trade accounts receivable
balance.

In 1997, 1996 and 1995, one customer accounted for 25%, 22% and 19% of revenues,
respectively. A second customer accounted for 12% of revenues in 1997, 1996 and
1995. The Company's largest customer is an automobile manufacturer. The Company
also provides transportation services to other manufacturers who are suppliers
for automobile manufacturers including the Company's largest customer. As a
result, concentration of the Company's business within the automobile industry
is greater than the concentration in a single customer. Of the Company's
revenues for 1997, 1996 and 1995, 41%, 37% and 40%, respectively, were derived
from transportation services provided to the automobile manufacturing industry.

COMPENSATION TO EMPLOYEES

Stock based compensation to employees is accounted for based on the instrinsic
value method under Accounting Principles Board Opinion No. 25, Accounting for
Stock Issued to Employees.

RECENT ACCOUNTING PRONOUNCEMENTS

In 1995, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of ("SFAS no. 121"). This statement was
adopted in the first quarter of 1996. The adoption of SFAS No. 121 did not have
a significant impact on the Company's financial position or results of
operations.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

2. ACQUISITIONS

On March 11, 1996, the Company closed the purchase of all of the outstanding
capital stock (the "Shares") of Allen Freight Services, Inc., a Missouri
corporation ("AFS"). The total purchase price for the shares was $200,000, which
was negotiated by the parties at arms length. Assets of approximately $2.2
million were acquired and liabilities of approximately $3.5 million were
assumed. The Company paid the purchase price by utilizing its existing line of
credit.

The acquisition has been accounted for under the purchase method, effective
March 11, 1996, with the operations of AFS included in the Company's financial
statements since that date. If the acquisition had occurred at the beginning of
fiscal 1996, the effect on consolidated operating revenues, net income and net
income per share would not have been material. The purchase price has been
allocated to assets and liabilities based on their estimated fair values as of
the date of the acquisition. Approximately $1.5 million in goodwill was recorded
as a result of the purchase allocation and is being amortized over a 25-year
period. The Company also entered into three-year non-competition agreements with
four former shareholders and officers/employees of AFS.

On January 31, 1995, the Company acquired substantially all the assets and
liabilities of Choctaw Express, Inc. and Choctaw Brokerage, Inc. based in
Oklahoma, (collectively "Choctaw"). Assets of approximately $2.7 million were
acquired and liabilities of approximately $.8 million were assumed. The total
purchase price for Choctaw was approximately $2.5 million.

2. ACQUISITIONS (continued)

The acquisition has been accounted for using the purchase method, effective
January 31, 1995, with operations included in the Company's financial statements
beginning on the acquisition date. The purchase price has been allocated to
assets and liabilities based on their estimated fair values as of the date of
acquisition. Goodwill in the amount of $600,000 was recorded as a result of the
purchase allocation and is being amortized over a 25-year period. The Company
entered into a five-year non-competition agreement with the former shareholder
of Choctaw which provides for payment of approximately $300,000 per year.

Pro forma unaudited financial information (as if the Choctaw acquisition was
completed at the beginning of the respective periods) for 1995 is provided

As of December 31, 1997, the Company has Federal net operating loss and
investment tax credit carryovers of approximately $2.3 million and $1.1 million,
respectively. The net operating loss carryovers begin to expire in 2003 and the
investment credit carryovers begin to expire in 1999. The current taxes provided
in 1997, 1996 and 1995 result from alternative minimum taxable income. The
Company has alternative minimum tax credits of approximately $3.0 million at
December 31, 1997 which carryover indefinitely.

Income taxes paid totaled approximately $1,300,000, $400,000 and $400,000 for
the years ended December 31, 1997, 1996 and 1995, respectively.

6. SHAREHOLDERS' EQUITY

The Company maintains an incentive stock option plan, a nonqualified stock
option plan, and an employee stock option plan for the issuance of options to
directors, officers, key employees and others. The option price under these

1997 must be exercised within six years from the date of grant and vest in
increments of 20% each year. Outstanding nonqualified stock options at December
31, 1997 must be exercised within five to six years and certain nonqualified

The Company adopted the disclosure-only provisions of Statement of Financial
Accounting Standards No. 123, Accounting for Stock-Based Compensation ("SFAS No.
123"). Accordingly, no compensation cost has been recognized for the stock
option plans. Had compensation cost for the Company's stock option plans been
determined consistent with the provisions of SFAS No. 123, the Company's net
income and earnings per share would have been reduced to the pro forma amounts
indicated below:

6. SHAREHOLDERS' EQUITY (continued)

Because the SFAS 123 method of accounting has not been applied to options
granted prior to January 1, 1995, the resulting pro forma compensation cost may
not be representative of that to be expected in future years.

The fair value of each option grant is estimated on the date of grant using the
Black-Scholes option pricing model with the following weighted average
assumptions: dividend yield of 0%; expected volatility of 65.15% to 76.64%;
risk-free interest rate of 5.73% to 7.02%; and expected lives of five years.

The majority shareholder exercised stock warrants to purchase an aggregate of
3,092,000 shares of the Company's common stock at $1.50 per warrant on December
30, 1996.

7. EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, Earnings Per Share ("SFAS No. 128"), establishing new standards for
computing and presenting earnings per share. The provisions of SFAS No. 128 are
effective for financial statements issued for periods ending after December 15,
1997. The Company has adopted SFAS No. 128 effective December 31, 1997, and all
earnings per share amounts for all periods have been presented, and where
appropriate, restated to conform to the SFAS No. 128 requirements. Basic
earnings per common share were computed by dividing the income by the weighted
average number of shares outstanding during the period. Diluted earnings per
share were computed assuming the exercise of stock warrants and options to
purchase a total of .3 million, 3.3 million, and 3.5 million shares of common
stock, for 1997, 1996, and 1995, respectively, as determined by applying the
treasury stock method. Under the treasury stock method of computing earnings per
share, the number of shares of treasury stock assumed repurchased is limited to
20% of common stock outstanding, with the remaining shares assumed to be newly
issued, and the excess proceeds assumed to have reduced long-term borrowings
outstanding for the year.

8. RELATED PARTY TRANSACTIONS

The Company provides motor carrier services to an affiliate of its majority
shareholder. Revenues from these transactions totaled approximately $14.5
million, $.4 million and $5.3 million for 1997, 1996, and 1995, respectively.

During 1993, the Company began leasing certain revenue equipment with an
original cost of $2.7 million to an affiliate of the majority shareholder under
a direct financing lease arrangement. The Company earned interest income of
$31,000 and $200,000 1996 and 1995, respectively, relating to this lease which
is included in other income in the accompanying financial statements. The
Company received full payment of the remaining balance on the lease agreement
during 1996 in the amount of $1.1 million.

8. RELATED PARTY TRANSACTIONS (continued)

Payments made by the Company to an affiliate of the majority shareholder for the
reimbursement of operating and other expenses paid on behalf of the Company and
debt repayments made on notes payable to the affiliate aggregated approximately
$.9 million, $6.4 million and $6.8 million in 1997, 1996, and 1995,
respectively.

Trade accounts payable at December 31, 1997 includes a payable to an affiliate
of the majority shareholder of $1,089,000.

9. LEASES AND COMMITMENTS

The Company leases certain revenue equipment under capital leases.

The future minimum payments under these leases (see Note 4) at December 31, 1997

13. FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used by the Company in estimating
fair value disclosures for financial instruments:

Cash and cash equivalents - The carrying amount reported in the balance sheet
for cash and cash equivalents approximates fair value.

Long-term debt - The fair values of the Company's long-term debt are estimated
using discounted cash flow analyses, based on the Company's current incremental
borrowing rates for similar types of borrowing arrangements.

Line of credit - The carrying amount for the line of credit approximates fair
value.

The carrying amounts and fair values of the Company's financial instruments at
December 31 are as follows (in thousands):

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE.

       On November 19, 1996, the Company dismissed its independent auditors,
Ernst & Young LLP, and on the same date engaged the firm of Arthur Andersen LLP
as its independent auditors for the fiscal year ending December 31, 1996. Each
of these actions was approved by the Board of Directors of the Company.

       The reports of Ernst & Young LLP on the financial statements of the
Company for the fiscal year ended December 31, 1995 did not contain an adverse
opinion or a disclaimer of opinion, nor were they qualified or modified as to
uncertainty, audit scope, or accounting principles.

       In connection with the audit of the Company's financial statements for
the year ended December 31, 1995, and in the subsequent interim period prior to
the dismissal of Ernst & Young LLP, there were no disagreements with Ernst &
Young LLP on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which disagreement, if not
resolved to the satisfaction of Ernst & Young LLP, would have caused it to make
reference to the subject matter of the disagreement in its report.

       Ernst & Young LLP has furnished the Company with a letter addressed to
the Securities and Exchange Commission stating that it agrees with the above
statements, a copy of which has been filed as an exhibit to the Current Report
on Form 8-K dated November 19, 1996.

                      P.A.M. TRANSPORTATION SERVICES, INC.
                           INCENTIVE COMPENSATION PLAN
                              (YEARS 1998 AND 1999)


        THIS IS THE INCENTIVE COMPENSATION PLAN of P.A.M. Transportation
Services, Inc., a Delaware corporation (the "Company"), under which bonuses may
be granted to certain employees of the Company and its subsidiaries subject to
the limitations, provisions and requirements hereinafter stated.
The Plan is as follows:

        1.      PURPOSES.  The purposes of the P.A.M. Transportation Services,
Inc. Incentive Compensation Plan (the "Plan") are as follows:

                (a) To encourage each participant in the Plan to make
exceptional contributions to further the growth, success and profits of the
Company.

                (b) To foster teamwork and personal involvement in the Company's
success.

                (c) To provide the Company with an objective method of
recognizing and rewarding certain employees who have been or will be given
substantial responsibility for the direction and management of the Company.

        2. ADMINISTRATION OF PLAN. This Plan shall be administered by the
Compensation and Stock Option Committee of the Company's Board of Directors (the
"Committee"). This Committee shall interpret the Plan in a manner consistent
with its purposes; and, subject to the terms of the Plan, will have discretion
to determine who shall participate in the Plan and the amounts of any incentive
compensation to be awarded pursuant to the Plan. All actions and determinations
of the Committee taken in connection with the Plan, including the awarding of
any incentive compensation, shall be final and conclusive. The Committee may
adopt rules from time to time for carrying out the Plan.

        3. ELIGIBLE EMPLOYEES. Upon the adoption of the Plan and at or near the
start of each succeeding calendar year, all full-time employees of the Company
and its subsidiaries, excluding those employees who are eligible to participate
in any other cash bonus plan of the Company or any subsidiary, shall be eligible
to participate in the Plan during such calendar year. Additionally, the
Committee may, in its discretion, allow a recently promoted or hired officer or
employee to participate in the Plan commencing with the date of his promotion or
his employment, as the case may be.

        In order to be considered an "Eligible Employee" for purposes of the
Plan and except as provided in Section 4(d), each participant must be employed
without interruption during the applicable calendar year from January 1 through
December 31 and furthermore must be employed at the time that the bonus is
actually paid pursuant to Section 4(c). In the event that the participant's
employment is terminated, by reason of (i) discharge with or without cause or
(ii) voluntary termination by the participant, at any time during the calendar
year, such terminated participant shall not be entitled to any bonus for such
calendar year.

        There shall be two classes of Eligible Employees as follows:

        (a) Class I shall include the chief executive officer, the chief
operating officer and the chief financial officer, respectively, of the Company,
and such additional officers and other key employees of the Company or its
subsidiaries as may be selected by the Committee or by the Board of Directors to
be

<PAGE>   2


eligible for participation in the Plan under the Class I category at the
beginning of any applicable calendar year.

        (b)     Class II shall include all Eligible Employees under the Plan 
other than those employees included in Class I.

        4.      MECHANICS OF THE PLAN.  The Plan will award participants for
above-average performance, measured by the Company's operating ratio, subject to
the following rules:

                (a) Annual Plan.  This Plan is an "annual plan" and incentive
awards shall be based on audited results of operations for each respective
fiscal year ending December 31.

                (b) Incentive Awards. The Board of Directors or Committee shall
establish the targeted operating ratios and corresponding bonus percentages for
each calendar year at or near the completion of the audit of the Company's
financial statements for the previous calendar year; provided, however, that the
targeted operating ratios and bonus percentages for the 1994 calendar year shall
be established by the Board of Directors upon the adoption of this Plan. Upon
adoption by the Board of Directors or Committee, the targeted operating ratio
and bonus percentages for the current calendar year shall be set forth on a
schedule and attached hereto as an exhibit. Under the Plan, each participant may
be awarded a bonus equal to the percentage of his annual base compensation which
corresponds to the Company's operating ratio for that calendar year. For
example, assume a participant has annual base compensation of $50,000 and the
Committee established the following targeted operating ratios and corresponding
bonus percentages for that calendar year:

<TABLE>
<CAPTION>

                Operating Ratios                  Bonus Percentage
                ----------------                  ----------------
                <S>                               <C>
                85.1% and over                                 0%
                84.1% to 85.0%                                 5%
                83.1% to 84.0%                                10%
                82.1% to 83.0%                                20%
                81.1% to 82.0%                                25%
                80.1% to 81.0%                                30%
                80.0% or less                                 40%
</TABLE>

If the operating ratio of the Company for the calendar year was 85.5%, the
participant would not be entitled to a bonus. If the operating ratio of the
Company for the calendar year was 80.5%, the participant would be entitled to a
bonus equal to $50,000 x 30% or $15,000.

                (c) Payment of Awards. Any bonus awarded hereunder shall be paid
by the Company upon the determination of the operating ratio for such calendar
year by the Company's independent accountants; provided, however, the bonuses
shall be paid no later than ninety (90) days after the end of each calendar
year.

                (d) Death or Disability. Notwithstanding anything contained
herein to the contrary, if a participant's employment ceases on account of death
or total disability, as defined in ss. 105(d)(4) of the Internal Revenue Code,
such participant shall be entitled to receive a pro-rata portion of any bonus he
otherwise would be awarded. In either event, the participant shall be entitled
to an amount equal to a normal bonus award under Section 4(b) multiplied by a
fraction the numerator of which shall be the number of days in the year during
which the participant was participating in the Plan and the denominator of
which shall be 365 days. For example, a participant with annual base
compensation of $50,000 dies on

                                       -2-

<PAGE>   3



July 1 of a calendar year. The Company has an operating ratio of 80.5% for that
calendar year which otherwise would entitle the participant to a bonus of 30% of
his annual base compensation or $15,000. Such participant would be entitled to a
bonus equal to $15,000 x 182/365 or $7,479. All bonus amounts payable to a
deceased or disabled participant shall be paid to such participant or his
personal representative, as the case may be.

           (e)    Recently Promoted or Hired Employees. In the event the 
Committee allows a recently promoted or hired employee to participate in the
Plan, such participant shall be entitled to receive a pro-rata portion of any
bonus he otherwise would be awarded. Such pro-rata bonus shall be the amount
equal to a normal bonus award under Section 4(b) multiplied by a fraction the
numerator of which shall be the number of days in the year during which the
participant was participating in the Plan and the denominator of which shall be
365 days. For example, a participant commences participation in the Plan on July
1 of a calendar year at annual base compensation of $60,000. The Company has an
operating ratio of 80.0% for that calendar year which otherwise would entitle
the participant to a bonus of 40% of his annual base compensation or $24,000.
Such participant would be entitled to a bonus equal to $24,000 x 183/365 or
$12,033.

           (f)    Applicable Base Annual Compensation.  For purposes of 
calculating all bonus awards hereunder, whenever the term "annual base
compensation" of a participant is referred to in this Plan it shall mean the
following:

                  i)    With respect to any eligible employee who is
compensated  on the basis of a fixed salary, annual base compensation shall be
the amount of such base salary determined at December 31 of each calendar year.

                  ii)   With respect to any eligible employee who is 
compensated  on the basis of hourly wages, the annual base compensation shall
be equal to the base wage of such eligible employee at December 31 of each
calendar year and then annualized.

           (g)    Operating Ratio. The "operating ratio" for any calendar year
means operating expenses as a percentage of operating revenues. For purposes of
this Plan, operating revenues shall not include interest income, other
non-operating income or extraordinary items, and operating expenses shall not
include any incentive compensation awarded hereunder, interest expense or income
taxes but shall include loss (gain) on sale of equipment. For purposes of this
Plan, the operating ratio shall be determined to the nearest one-hundredth of
one percent (.01%).

        5. NOTICES. The Board of Directors or the Committee shall notify all
employees selected to participate in the Plan as soon as practicable after such
determination has been made. The participants shall be notified of the targeted
operating ratios and corresponding bonus percentages for each calendar year, and
any subsequent modifications thereto, as soon as practicable after such
determinations have been made by the Committee.

        6. OTHER BENEFITS. This Plan is intended to provide a method of
rewarding employees for exceptional contributions made by such employees and any
awards hereunder are intended to be in addition to any other benefits which the
Company provides to the participants. The Board of Directors or the Committee
may, but is not obligated to, award one or more of the participants additional
bonuses in such amounts and at such times as the Board of Directors or the
Committee, in its sole discretion, shall determine.

        7. AMENDMENTS TO PLAN. The Board of Directors or the Committee may from
time to time make such amendments to the Plan as the Board or the Committee, in
its sole discretion, shall deem desirable, including modifying the targeted
operating ratios and the corresponding bonus percentages established pursuant to
Section 4(b) at any time during a calendar year.

        8. TERMINATION OF THE PLAN. The Board of Directors may at any time
terminate the Plan. In the event the Plan is terminated, the Company shall not
have any obligation to the participants under the Plan unless the Board of
Directors states that the Company has assumed an obligation. For example, assume
the Plan is terminated on December 15 of a calendar year. No participant shall
have a right to receive, and the Company shall not have any obligation to pay,
any bonus amount under the Plan for that calendar year unless the Board of
Directors expressly states the Company shall pay such bonus amount.

        9. NONASSIGNABILITY. No participant shall have the right to assign or
transfer any of his benefits or expected benefits under the Plan except by will
or by the laws of descent and distribution.

        This Plan has been adopted and approved at a meeting of the Board of
Directors of the Company on the 17th day of October, 1997, and shall be
effective for calendar years 1998 and 1999, unless otherwise amended by the
Board of Directors.
