RAE SYSTEMS, ALL SET TRACKING JOIN FORCES TO RESPOND TO MARITIME TRANSPORTATION SECURITY ACT

Smart and secure containers feature internal sensors and communications to ensure integrity and security from shipping point to destination

SUNNYVALE, Calif. April 28, 2003 RAE Systems, (OTC BB: RAEE.OB) the hazardous environment detection company, and All Set Tracking AB, a provider of technology and security solutions to intermodal container transportation companies around the world, today announced that the companies are joining forces to respond to the U.S. Governments Maritime Transportation Security Act, signed into effect as Public Law 107-295 by President George W. Bush in November of 2002. The goal of the partnership is to offer joint solutions that address the security and integrity of the ocean freight that enter the United States 361 seaports each year.

Last year, more than 13 million shipping containers entered the United States, and less than two percent of these
were inspected, said Bob Chen, CEO of RAE Systems. Manual inspection of each container is simply not possible, so the role of pervasive, integrated container sensing and communications technologies is critical to our homeland defense. Our agreement with All Set Tracking provides a powerful technology solution to this important issue, and will offer peace of mind to shippers and citizens alike.

Continued Chen, A terrorist event at a cargo port would substantially disrupt the world economy. A recent report from the Brookings Institution stated that the illicit entry of weapons of mass destruction shipped in containers into the U.S. has the potential to cause the shutdown of deliveries, physical destruction, massive injuries and loss of lives. The report goes on to estimate that this potential economic devastation could be as high as $1 trillion.

RAE Systems family of hazardous environmental detection solutions can be customized for almost any maritime situation where a chemical, gaseous or radiological threat exists. The products can be calibrated to detect hundreds of different chemicals, a broad range of toxic substances, gamma and neutron radiation.

RAE Systems chemical and gas sensors are ultra-sensitive and can detect VOCs and other toxins within the 1ppb 10,000-ppm range in confined space of a cargo container. And unlike dosimeters, which provide weighted averages over time, RAE Systems radiological sensors are 20-50 times more sensitive than Geiger Muller or He tube technology of the same size and deliver instantaneous feedback.

Under terms of the marketing and engineering agreement, RAE Systems and All Set will jointly design a series
of sensors and sensor interfaces for Smart and Secure Container products in coordination with and to be
manufactured by CIMC (China International Marine Containers Co. Ltd.) to meet the needs of specifically identified market segments. CIMC is the largest manufacturer in the world of new ISO freight containers, with approximately a 40% market share and annual production in excess of 700,000 TEUs (twenty-foot equivalent units).

In addition to the new (OEM) container market, RAE Systems and All Set will develop a similar set of sensors
for the existing world fleet of some 13 million ISO International Standards Organization) intermodal freight containers to interface to All Sets ALLSeal product line. RAE Systems will have primary responsibility for sensor and related power supply design while All Set will have primary responsibility for design and development of the container e-sealing, processing and radio communications components and responsibility for the mechanical design of the container through its collaboration with CIMC.

We are pleased to include RAE Systems as a team member for our CIMC/All Set Safe and Secure Container
initiative, said Karl Bohman, CEO of All Set. The need for enhanced security in the global intermodal
transportation chain is clear and immediate, and the available market is quite substantial.
