OSI Systems Receives Contracts for Approximately $4 Million for Hold Baggage Screening Systems

HAWTHORNE, Calif., Jul 01, 2008 (BUSINESS WIRE) -- OSI Systems, Inc. (NASDAQ: OSIS), a vertically-integrated provider of specialized electronic products for critical applications in the Security and Healthcare industries, announced today that its Security Division, Rapiscan Systems, has received contracts totaling approximately $4 million from six regional Australian airports for its Rapiscan MVXR5000 Inline Automated Hold Baggage Screening Systems ("HBS").

The systems are to be installed at regional airports across Australia. The contract awards are the result of an Australian Federal Government mandate in May 2007 for select regional airports to provide 100 percent inspection of checked baggage by December 2008.

The Rapiscan MVXR5000 is designed for the aviation industry for the inspection of checked baggage and has been deployed successfully in airports worldwide. The system provides automated explosives detection with low false alarm rates by utilizing multi-view dual-energy X-ray to produce high quality images. The systems can be integrated into existing baggage conveyor infrastructures operating at speeds up to 1,800 bags per hour. The high throughput and automatic detection is coupled with the systems' advanced network capabilities to allow near-real time suspicious bag analysis to be completed by a networked group of remote operators. Images are then transmitted to the manual inspection stations as a search aid. The Rapiscan MVXR5000 has multiple layers of network redundancy designed to ensure the highest levels of system availability and fail-safe operation for the most demanding aviation security environments.
