ITEM 5.  OTHER EVENTS

         On December 30, 1999, Dynamex Inc. (the Company) issued a press release
providing an update on a number of issues relating to the ongoing audits of the
Company's financial statements, preliminary first quarter 2000 results and other
related topics. In addition to the preliminary quarterly results the Company
indicated the filing of its FY99 Form 10-K and amended prior period reports will
be delayed approximately 60 days pending completion of the audit of its FY99
financial statements and re-audits of prior fiscal years. Based on the above and
resulting delays in timely filing audited financial statements with the SEC, the
American Stock Exchange (the Exchange) advised the Company it would no longer
meet the Exchange's continued listing guidelines after November 15, 1999.
Additionally, the Company indicated it has requested limited access to its line
of credit and a temporary waiver of covenants under its bank credit agreements.
Finally, the Company provided an update on a class action lawsuit and SEC
inquiry into the audits and restatement process. This press release is
incorporated herein as Exhibit 99.1.
