Rapiscan Announces $2.2 Million Order for Advanced Cargo Pallet Screening System for an Asian Location

HAWTHORNE, Calif., Oct. 16, 2002 -- Rapiscan Security Products, Inc., a wholly owned subsidiary of OSI Systems, Inc. (Nasdaq:OSIS), and a worldwide provider of comprehensive security solutions, today announced that Rapiscan has received an order for a cargo screening system representing approximately $2.2 million in sales. This system will be installed at an undisclosed location in Asia. Rapiscan expects to deliver the system within the next fiscal year ending June 30, 2003.

The system covered by the initial procurement order, designated the Advanced Cargo Pallet Screening System, will be used in a commercial freight-forwarding environment where a high volume of large cargo pallets must be screened rapidly. Each pallet passes through a tunnel in the air cargo screening system, which can handle most standard pallet configurations. The pallet will be X-rayed with Rapiscan technology, with the X-ray image undergoing computerized image enhancement before appearing on a computer screen for evaluation. Additional scanning technology will also be integrated into this system. The cargo screening system scans the entire pallet in one pass, comparing the resulting data with sophisticated computerized `threat models,' and assisting screening personnel to determine the location of potential suspect contents.

"We are pleased to announce another project for our large cargo group," said OSI Systems Chairman and CEO, Deepak Chopra. "This system represents an opportunity for us to demonstrate our ability to integrate multiple scanning technologies into one inspection platform. Our continued success especially in the international arena and in open competition with our competitors bodes well for our technology."

Rapiscan's large cargo scanning systems have gained increasing interest throughout the world, for use in preventing the infiltration of explosives, weapons, drugs, and other contraband, as well as for use by government agencies, in catching misrepresentations on shipping manifests, which deprives governments of tax revenue. Rapiscan's scanners are designed for locations such as air and sea-ports, land entry points, customs facilities, mail, freight or courier service installations.

Rapiscan constructs large cargo scanning systems to inspect items ranging from airplane pallets and Unit Load Devices (ULDs) to intermodal freight containers and entire trucks including tractor-trailer combinations. Rapiscan's X-Ray technology has been proven to be more effective than manual searches to rapidly compare contents with a cargo manifest. Rapiscan's systems remove the possibility of breakage and pilferage associated with manual inspection. Manual searches are also labor-intensive, slow and unpopular with shippers.
