Dynamex Announces Resignation of Independent Auditors.

Business Editors

DALLAS--(BUSINESS WIRE)--March 7, 2000

Dynamex Inc. (AMEX:DDN) announced today that Deloitte & Touche LLP has resigned as the Company's independent auditors. Dynamex today filed a Current Report on Form 8-K with the Securities and Exchange Commission relating to the resignation. The Company is conducting a search for a new independent auditor.

The Company also announced the receipt of a letter from The American Stock Exchange confirming the Exchange's intention to proceed with the filing of an application with the SEC to strike the Company's common stock from listing and registration on the Exchange. The Company has not complied with the Exchange's continued listing rules in that it has failed to file its July 31, 1999 Form 10-K and its October 31, 1999 Form 10-Q as well as file amended Forms 10-K for fiscal 1997 and 1998. The Company will appeal this decision, and the appeal will stay the delisting until a final decision following the appeal hearing. It is anticipated the appeal hearing will be held in the next 14 to 45 days.

Trading in the Company's common stock will remain halted during the appeal process. In the event of an unfavorable appeal decision by the Exchange or a withdrawal of the appeal, the Company will make all reasonable efforts to have the common stock quoted on the National Quotation Bureau's Electronic Quotation System known as the "EQS" or the "Electronic Pink Sheets". Management can make no assurance with respect to the quotation, timing of quotation, trading or date of trading in the Company's common stock.

As discussed in previous press releases, the Company is in violation of certain financial reporting covenants under its bank credit agreement and may be in violation of other financial covenants and certain terms and conditions. The bank group approved a waiver in early February 2000 permitting the increase in a letter of credit related to insurance. The Company will continue to work with its banks to achieve any necessary forbearance, waivers or amendments. However, there is no assurance that such forbearance, waivers or amendments will be achieved.

This release contains forward-looking statements which involve assumptions regarding Company operations and future prospects. Although the Company believes its expectations are based on reasonable assumptions, such statements are subject to risk and uncertainty, including, among other things, those that may arise during the completion of the Company's fiscal year 1999 audit or the preparation of restated financial statements for fiscal year 1997, fiscal year 1998, and each quarter commencing with the first quarter of 1997 (including the possibility that additional entries may be identified that impact the Company's financial results for the current and/or prior reporting periods or that there may be a change in the period in which certain of the adjustments are recorded), the possibility that the Company's stock will be delisted from the American Stock Exchange, any action resulting from defaults under the Company's bank credit agreement, the outcome of the shareholder class action and SEC inquiry, acquisition strategy, competition, foreign exchange, and risks associated with the local delivery industry. These and other risks are mentioned from time to time in the Company's filings with the Securities and Exchange Commission. In light of such risks and uncertainties, the Company's actual results could differ materially from such forward-looking statements.
