OSI Receives $3.4 Million Order for Hybrid-Technology Large Cargo Systems; To Be Used for Inspection of Air Cargo Containers

OSI Systems, Inc. (Nasdaq:OSIS) today announced that its wholly owned subsidiary, Rapiscan, has received a $3.4 million order from an international customer for hybrid-technology large cargo inspection systems and associated maintenance.

The hybrid-systems are to be installed at major international airports and used for the inspection of bulk air cargo. The systems are scheduled to be delivered in the second half of fiscal 2005.

These hybrid-systems will conduct a two-phased inspection process; imaging and material-specific inspection. The inspection process eliminates the current costly need to manually open, unpack, inspect and repack the contents of the air cargo container, thereby significantly improving throughput and reducing false alarm rate.

During the first phase of the inspection, the container is scanned with our imaging technology. The image is interpreted by the operator for manifest verification and threat detection. If a suspicious object is identified during this process, the operator has the ability to scan the container with the material-specific technology. This technology will automatically produce a "red light/green light" response for the operator, minimizing human error and false alarms, which result in costly and time-consuming manual inspection.

"We continue to expand our customer base in the international markets for large cargo systems. This unique hybrid-system demonstrates the ability and willingness of the OSI Security Group to develop products for our customers' needs, utilizing the broad range of inspection technologies that we have available," stated Mr. Ajay Mehra, President of OSI Security Group.
