                         DYNAMEX ANNOUNCES THIRD QUARTER
                            FISCAL YEAR 2003 RESULTS

THIRD QUARTER HIGHLIGHTS:
o  SALES INCREASE 9.0% TO $62 MILLION.
o  NET INCOME TOTALS $2.1 MILLION OR $0.18 PER FULLY DILUTED SHARE.
o  BANK CREDIT FACILITY EXTENDED THROUGH NOVEMBER 30, 2005.
o  MANAGEMENT RAISES OUTLOOK FOR FY 2003 AND AFFIRMS FY 2004.

JUNE 4, 2003 -- DALLAS, TEXAS -- Dynamex Inc. (Amex: DDN), a leading provider of
same-day delivery and logistics services in the United States and Canada, today
announced net income of $2.1 million or $0.18 diluted earnings per common share
for the FY 2003 third quarter versus net income of $1.3 million or $0.12 diluted
earnings per common share for the same period last year. Current year net income
includes income tax benefits of approximately $425,000 ($0.04 per share)
associated with Dynamex Canada Corp.'s payment of a $2.5 million cash dividend
to Dynamex Inc. this quarter. Current year earnings per share also include the
impact of the issuance of 700,000 common shares during the third quarter of FY
2002.

FY 2003 third quarter sales were $62 million, 9.0% higher than the prior year.
Current year sales were positively impacted by the strengthening Canadian
dollar. The favorable change in the exchange rate between the Canadian dollar
and the U.S. dollar in the current year versus the prior year had the effect of
increasing sales $1.4 million in the current year quarter. Excluding the impact
of the exchange rate, sales were 6.5% higher in the current year quarter than
last year, in line with the Company's outlook of 5% to 9% year-over-year growth.
On demand sales, which currently represent approximately 47% of sales, were 6.0%
higher while other services were 11.8% higher.

Earnings before interest, taxes, depreciation and amortization ("EBITDA") were
$3.4 million (5.5% of sales) in the FY 2003 third quarter compared to $3.4
million (6.0% of sales) in the prior year. Current year EBITDA was negatively
impacted by the write-off of receivables from Air Canada ($200,000) and costs
related to the start-up of new business ($60,000) as well as the impact of
unusually harsh weather conditions in both the U.S. and Canada.

Selling, general and administrative ("SG&A") expenses were $14.4 million in the
current year quarter compared to $13.7 million in last year's quarter. SG&A
expenses were 23.2% of sales in the current year quarter compared to 24.0% in
the same quarter last year. Approximately $0.3 million of the increase results
from the change in the exchange rate between the Canadian dollar and the U.S.
dollar in the current year versus the prior year. Higher wages and benefits, the
result of an increase in sales and operating personnel to support expanding
operations along with the lifting of the salary freeze, higher unemployment
taxes and medical insurance, account for most of the remaining increase.

THIRD QUARTER HIGHLIGHTS

"We delivered improved financial results during the third fiscal quarter despite
the sluggish economic environment and some unusually harsh weather conditions.
We maintained a healthy momentum in sales growth with all three of our revenue
streams increasing during the period and we are particularly pleased with the
execution and results from our national accounts programs. Even though the
period was challenging due to increases in healthcare costs and general
insurance and the Air Canada write-off, we were able to manage our costs
accordingly to offset the financial impact of these issues. We have also
implemented plans to compensate for some of these increases going forward," said
Dynamex Chairman and Chief Executive Officer, Rick McClelland.

"Our unique position in the same-day transportation industry is proving
beneficial to the Company under current economic conditions. While the weak
economy has resulted in lower volumes from some accounts, new business activity
has increased and thus offsets this decline. With the current economic market,
shippers are seeking ways to reduce costs, reduce assets and improve customer
service in all areas of their business related to the final delivery of their
products whether it is on a local, regional or national basis. As a result, our
distribution and outsourcing services are doing especially well. We are
benefiting from solid execution and from the significant investments we have
made in the network of businesses that we acquired and integrated, the
development of our same day service menu, our local, regional and national sales
initiatives, and our industry leading technology," McClelland added.

"Our financial outlook remains firm as we go into the fourth quarter of this
fiscal year. We are focused on continued improvement in our overall financial
performance, reducing debt and maintaining a strong balance sheet. We believe
our business is well positioned for continued growth," McClelland concluded.

GROSS PROFIT MARGIN

The gross profit margin for the current year quarter was 28.7% compared to 29.9%
in the prior year. The reduced gross margin percentage is primarily attributable
to the write-off of receivables from Air Canada due to their filing under the
Companies' Creditors Arrangement Act (approximately $200,000), higher insurance
(approximately $310,000), costs related to new business startups (approximately
$60,000) and a change in business mix. On-demand sales were 47.4% of total sales
in the current quarter, compared to 48.7% in the prior year quarter.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization ("D&A") in the FY 2003 third quarter decreased to
$518,000 from $699,000 in the FY 2002 third quarter. As a percent of sales, D&A
decreased to 0.8% from 1.2% in the prior year. The reduction is primarily
attributable to lower capital expenditures in recent years and a switch to
two-way mobile data communication devices that require no capital expenditure.

INTEREST EXPENSE

Interest expense for the three months ended April 30, 2003 was $571,000, 14.4%
below the prior year period. This decrease is primarily attributable to lower
outstanding debt during the current quarter versus the prior year quarter and a
lower effective interest rate. As of April 30, 2003, long-term debt was $24.9
million, $8.5 million (25%) below the prior year.

BANK CREDIT AGREEMENT

On May 30, 2003, the Company amended and extended its bank credit agreement.
Under the terms of the amended agreement, the Company prepaid $1.2 million of
the amortizing term loan from available cash and the facility was extended
through November 30, 2005. The amended agreement consists of an amortizing term
loan of $13 million and a revolving credit facility of $19.5 million. Required
principal payments, on the amortizing term loan, consist of $1.375 million
quarterly, with a final payment of $625,000 due on November 30, 2005. Interest
on outstanding borrowings is payable monthly at prime, plus a margin ranging
from 0.50% to 0.0%, or LIBOR, plus an applicable margin ranging from 3.5% to
2.0%, based upon the ratio of Total Debt to EBITDA, as defined. A ratio of Total
Debt to EBITDA of less than 1.75 to 1.00 will lower the applicable margin from
0.5% to 0.125% for prime based loans and from 3.5% to 2.5% on LIBOR based loans
and removes certain restrictions. At April 30, 2003, the Total Debt to EBITDA
ratio was 2.04 to 1.00.

OUTLOOK

The following outlook is provided in connection with Regulation FD to ensure
that all investors continue to have equal access to information. The following
outlook contains forward-looking statements that involve assumptions regarding
Company operations and future prospects. Caution should be taken that the actual
results could differ materially from those stated or implied in this and other
Company communications.

The Company expects FY 2003 year-over-year Sales Per Day to increase between
5.5% and 6.5% compared to FY 2002, assuming the Canadian dollar remains at
current levels. The Company expects year-over-year Sales Per Day growth for
fourth quarter of FY 2003 to range between 9% and 11%.

In the FY 2003 4th quarter, Dynamex Canada Corp. is expected to pay Dynamex Inc.
approximately $1.6 million of accrued inter-company interest and royalties, net
of Canadian withholding taxes of $160,000. The Canadian taxes will be offset in
the Company's Statement

of Operations by the recognition of a foreign tax credit of $160,000. The cash
received by Dynamex Inc. will be used to further reduce outstanding debt.

The Company is raising its expectation for basic net income per share for FY
2003 from between $0.55 and $0.65 to between $0.60 and $0.70, due to the tax
benefit associated with the Canadian dividend and the strengthening Canadian
dollar.

The Company believes that sales will continue to strengthen and as this occurs,
net income should increase at a higher rate than sales due to the leverage from
our relatively fixed cost infrastructure and favorable U.S. income tax position.
The Company believes that an expected 10% increase in sales in FY 2004 should
result in net income per share of $0.75 to $0.85.

As on-demand sales decline as a percentage of total sales, and due to the rising
cost of cargo, liability and other insurance, the Company expects cost of sales
to continue to increase as a percentage of sales in FY 2004. SG&A expenses are
expected to increase in absolute dollars but decline as a percentage of sales.

The Company expects interest expense to decline as outstanding debt is repaid
and the applicable margin on the bank credit facility is reduced. The Company
expects to achieve a Total Debt to EBITDA ratio of less than 1.75 to 1.00 by the
end of the FY 2004 first quarter, resulting in a 1% reduction in the interest
rate.

The Company expects to pay only minimal cash income taxes in the U.S. in FY 2003
and FY 2004. For federal income tax purposes, the Company can offset
approximately $5.5 million of taxable income on an annual basis with goodwill
deductions. Purchased goodwill is amortized over 15 years for U.S. federal
income tax purposes. As the Company realizes the benefit of the goodwill
amortization, it records a reduction in deferred tax assets and a charge to
income tax expense using the Company's U.S. effective income tax rate, currently
at approximately 36%. Taxable U.S. income, in excess of the goodwill
amortization deduction, is expected to be offset by net operating loss
carryforwards. The current effective income tax rate for Canadian operations is
approximately 38%.
