                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Stockholder of Decker Transport Co., Inc. and Van Houten Ltd.:

We have audited the accompanying combined balance sheet of Decker Transport
Co., Inc. (an Ohio corporation) and Van Houten Ltd. (a New Jersey corporation)
as of December 31, 1998, and the related combined statements of income,
retained earnings and cash flows for the year then ended. These financial
statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Decker Transport Co., Inc. and
Van Houten Ltd. as of December 31, 1998, and the results of their operations
and their cash flows for the year then ended, in conformity with generally
accepted accounting principles.

                 DECKER TRANSPORT CO., INC. AND VAN HOUTEN LTD.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

                               DECEMBER 31, 1998



1.  NATURE OF BUSINESS:

The principal activity of Decker Transport Co., Inc. (Decker) is as a contract
and common transportation carrier throughout the United States and portions of
Canada. The principal activity of Van Houten Ltd. (Van Houten) is the leasing
of transportation equipment. Decker Transport Co., Inc. and Van Houten Ltd.
(collectively, the Companies) shared common management, resources and
ownership. On January 11, 1999, all of the Companies' assets, with the
exception of certain related party notes receivable and loans, were sold to a
subsidiary of P.A.M. Transportation Services, Inc. (P.A.M.), along with the
assumption of substantially all of the Companies' liabilities.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

PRINCIPLES OF PRESENTATION

The combined financial statements include the accounts of Decker and Van
Houten. All significant intercompany accounts and transactions have been
eliminated.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the year. Actual results
could differ from these estimates.

PROPERTY AND EQUIPMENT

Property and equipment are recorded at cost and depreciated on a straight-line
basis over the following estimated useful lives of the respective assets:

<TABLE>
<CAPTION>
                Asset Class                  Estimated Asset Life
         ------------------------            --------------------

         <S>                                 <C>
         Revenue equipment                         5-7 years
         Service equipment                         3-7 years
         Furniture and equipment                   5-7 years
</TABLE>



                                     -10-
<PAGE>   11

Maintenance and repairs are charged directly to expense as incurred; purchases
of items which will benefit future periods are capitalized. When assets are
disposed of, the cost and accumulated depreciation are removed from the
accounts and any resulting gain or loss is recorded.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

Estimated uncollectible accounts are provided based on historical experience
and management's evaluation of outstanding accounts receivable.

INCOME TAXES

The Companies have elected S-corporation status for federal and state income
tax purposes. Therefore, the results of operations of the Companies are
included in the stockholder's individual tax returns. Accordingly, no
provisions for income taxes related to current operations have been made for
the Companies in the accompanying financial statements, except for provisions
required due to certain states in which the Companies operate that do not
recognize S-corporation status for state income tax purposes.

PREPAID EXPENSES

Prepaid expenses include licenses, registrations and insurance which are
amortized over the applicable period. Prepaid expenses also include tires and
parts which are expensed when placed on revenue equipment. Tires purchased with
revenue equipment are capitalized as a cost of the related equipment.

ACCRUED LIABILITIES

With respect to cargo loss and auto liability, Decker maintains the following
insurance coverage and deductibles: The auto liability coverage is subject to a
$25,000 deductible per occurrence while the cargo loss coverage has a $5,000
deductible. The auto liability policy covers incidents up to $5,000,000. Decker
has an excess liability policy for an additional $5,000,000 in coverage. Cargo
losses are limited to $500,000 per occurrence. Decker maintains collision
coverage on leased vehicles. The policy has a $5,000 deductible. Decker also
maintains an excess physical damage policy with a $100,000 deductible and a
$3,000,000 limit on the entire fleet. Decker maintains a reserve for estimated
losses for claims incurred. Decker maintains workers' compensation with
coverage maintained for all claims up to $500,000. Decker has a reserve for
estimated losses from previous policy periods which had a retroactive plan or a
deductible of $100,000. Letters of credits are maintained in the amounts of
$345,000 for the auto liability policy and $65,000 for the expired workers'
compensation policy, which had a deductible of $100,000. A reserve has been
established which management believes is adequate.

Decker is self-insured to the extent of specific stop-loss limits for its
employees' health care claims. Insurance providers assist Decker in determining
its estimated liabilities for these self-insured



                                     -11-
<PAGE>   12

claims. Decker has an employee benefit plan to provide health care coverage for
its employees. Due to a stop-loss insurance policy, benefits payable by Decker
are limited to $50,000 per person during the policy year ending February 28,
1999, with an aggregate limit of $746,000 in claims.

REVENUE RECOGNITION POLICY

Decker recognizes revenue based upon pickup date and relative transit time in
each reporting period with expenses recognized as incurred.

BUSINESS SEGMENT AND CONCENTRATIONS OF CREDIT RISKS

Decker operates in one business segment, motor carrier operations. Decker
provides transportation services to customers throughout the United States and
portions of Canada. Decker performs ongoing credit evaluations and generally
does not require collateral. Decker maintains reserves for potential credit
losses and such losses have been within management's expectations. At December
31, 1998, two customers accounted for approximately 27% and 13% of the trade
accounts receivable balance. The same two customers accounted for approximately
24% and 15% of combined operating revenues for the year. Decker's largest
customer is a lawn and garden equipment manufacturer. This customer also
accounted for 69% of lease receivables.

The Companies finance a large portion of their revenue equipment and service
equipment through banks and other lending institutions. The notes payable are

                    Report of Independent Public Accountants



To the Board of Directors and Shareholders of
P.A.M. Transportation Services, Inc.


We have audited the accompanying consolidated balance sheets of P.A.M.
Transportation Services, Inc. and subsidiaries as of December 31, 1998 and
1997, and the related consolidated statements of income, shareholders' equity,
and cash flows for each of the three years in the period ended December 31,
1998. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of P.A.M.
Transportation Services, Inc. and subsidiaries as of December 31, 1998 and
1997, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles.

                                December 31, 1998


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 7.)

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 expected 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 in 1998, 1997, or
1996.

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). During 1998, the Company changed from being self-insured
for workers' compensation coverage in Arkansas, Oklahoma, Mississippi and
Florida with excess coverage maintained for claims exceeding $250,000, to being
fully-insured through Virginia Surety Insurance Company for workers'
compensation coverage in those states. The Company continues to be self-insured
for workers' compensation coverage in Ohio with excess coverage maintained for
claims exceeding $350,000. The Company has reserved for estimated losses to pay
such claims as incurred as well as 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 two letters of credit in the amount of $150,000
each 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 provisions 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 and Mexico. 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.

In 1998, 1997 and 1996, one customer accounted for 35%, 25% and 22% of revenues,
respectively. A second customer accounted for 12% of revenues in 1998, 1997 and
1996. 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 1998, 1997 and 1996, 53%, 41% and 37%, 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 intrinsic
value method under Accounting Principles Board Opinion No. 25, Accounting for
Stock Issued to Employees.

RECENT ACCOUNTING PRONOUNCEMENTS

The Company adopted the provisions of Statement of Financial Accounting
Standards No. 129, Disclosures of Information about Capital Structure, ("SFAS
No. 129") effective for the year ended December 31, 1997. This Statement
consolidates existing pronouncements on required disclosures about a company's
capital structure including a brief discussion of rights and privileges for
securities outstanding. The adoption of this Statement had no material effect on
the Company's consolidated financial statements.

1.  ACCOUNTING POLICIES (continued)

In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, Reporting Comprehensive Income, ("SFAS
No. 130"). This Statement requires that all items that are required to be
recognized under accounting standards as components of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements. SFAS No. 130 is effective for fiscal years beginning
after December 15, 1997. The adoption of this Statement had no material effect
on the Company's consolidated financial statements.

In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, Disclosures about Segments of an
Enterprise and Related Information, ("SFAS No. 131"). This Statement established
standards for reporting information about operating segments in annual financial
statements and requires reporting of selected information about operating
segments in interim financial reports issued to stockholders. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. SFAS No. 131 is effective for financial
statement periods beginning after December 15, 1997. The adoption of this
Statement had no material effect on the Company's consolidated financial
statements.

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities, ("SFAS No. 133"). SFAS No. 133 establishes accounting
and reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair value. SFAS
No. 133 requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative's gains and losses to
offset related results on the hedged item in the income statement. Companies
must formally document, designate, and assess the effectiveness of transactions
that receive hedge accounting. SFAS No. 133 is effective for fiscal years
beginning after June 15, 1999; however, companies may implement the statement as
of the beginning of any fiscal quarter beginning on or after June 16, 1998.

SFAS No. 133 cannot be applied retroactively and must be applied to (a)
derivative instruments and (b) certain derivative instruments embedded in hybrid
contracts that were issued, acquired, or substantively modified after December
31, 1997 (and, at the company's election, before January 1, 1998). The Company
has not yet quantified the impact of adopting SFAS No. 133 on its financial
statements and has not determined the timing of or method of the adoption of
SFAS No. 133. However, as of December 31, 1998, the Company had no outstanding
derivative instruments.

RECLASSIFICATIONS

Certain reclassifications have been made to prior years' consolidated financial
statements to conform to the current year presentation.

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.

5. SHAREHOLDERS' EQUITY (continued)

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:

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.

6. 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 calculated as follows:

value.
