Credit Facility Upgraded by Agent Bank

Dynamex Inc. (AMEX:DDN), a leading provider of same-day delivery and logistics services in the United States and Canada, today announced Jeffrey N. MacDowell, Vice President-Finance and Corporate Development has resigned to join American Capital Strategies, Ltd. (Nasdaq:ACAS), a publicly traded buyout and mezzanine fund, as a principal in its Dallas office.

The Company also announced the promotion of Sharon L. Taylor to Director-Finance and Investor Relations to assume Mr. MacDowell's responsibilities in the areas of bank relations, investor relations and treasury. Ms. Taylor joined Dynamex in January 2001 from Union Pacific Resources where she was Assistant Treasurer in charge of bank relations with UPR's approximately 25 banks. Prior to joining UPR, Ms. Taylor was Vice President-Controller of United LP Gas Corporation, a privately held, energy marketing company with over $100 million in revenue.

Mr. MacDowell commented, "This was a very difficult decision in light of our accomplishments at Dynamex over the past two years and the opportunity for growth to leverage the Company's infrastructure of systems and people in the near future. However, I leave my responsibilities in capable hands and with confidence that Dynamex will capitalize on its unique market position in the same-day transportation and logistics industry."

Rick McClelland, Chairman and CEO, said, "During his tenure at Dynamex Jeff made many valuable contributions and we wish him well. One of the most important was the organization and development of a great team in the Finance, Treasury and Investor Relations area. And that team is very capable of executing on a go forward basis."

Dynamex also announced that Bank of America, the agent bank on its $50 million credit facility, upgraded the Company's loan and transferred the credit out of the bank's Special Assets Division. Bank One, another of the Company's five banks, also recently took similar action.
