NASDAQ DETERMINES MINORPLANET SYSTEMS USA, INC. TO RETAIN LISTING ON NASDAQ
SMALLCAP MARKET SUBJECT TO EXCEPTIONS

RICHARDSON, TEXAS, MAY 5, 2004 - Minorplanet Systems USA, Inc. (NASDAQ: MNPQC),
a leading provider of telematics-based management solutions for commercial
fleets, today announced that the company had received a written determination
notice from the Nasdaq Listing Qualifications Panel on May 3, 2004 indicating
that the company's securities would remain conditionally listed on The Nasdaq
SmallCap market subject to the following exceptions:

o        On or before May 28, 2004, the company must submit documentation to the
         Nasdaq evidencing that a hearing before the Bankruptcy Court for the
         approval of the company's Disclosure Statement was held;

o        On or before Jun. 30, 2004, the company must submit documentation to
         the Nasdaq evidencing confirmation of the company's plan of
         reorganization by the Bankruptcy Court and compliance with all
         requirements for continued listing on The Nasdaq SmallCap Market upon
         emergence from bankruptcy except for those deficiencies for which the
         company has been granted a "grace period" within which to regain
         compliance.

Pursuant to Nasdaq Marketplace Rule 4310(c)(8)(D), the Panel also granted the
company a 180-day grace period to achieve compliance with the $1.00 minimum bid
price requirement.

         The Panel further indicated that effective on the opening of business
on May 5, 2004, the trading symbol for the company's securities will be changed
from MNPLQ to MNPQC to indicate the conditional listing on The Nasdaq SmallCap
Market. As per the Panel, the fourth character "Q" will remain appended to the
company's trading symbol pending the company's emergence from bankruptcy, and
the fifth character "C" will be removed from the company's symbol upon
confirmation of the company's compliance with the terms of the exceptions and
all other criteria for continued listing.

         "We currently expect to obtain confirmation of our plan by Jun. 30,
2004 and retain the company's Nasdaq listing," said Dennis Casey, president and
chief executive officer. "In fact, the disclosure statement hearing is set for
May 24, 2004, ahead of the May 28, 2004 deadline." In closing remarks Mr. Casey
said, "We believe that the company will emerge from chapter 11 with a much
improved capital and expense structure and be well positioned to capitalize on
the large and growing market for mobile tracking and communications."
