OSI Systems Chairman and CEO to Testify Before Congress on Aviation Checkpoint Security

OSI Systems, Inc. (Nasdaq:OSIS - News), today announced that its Chairman and CEO, Deepak Chopra, will testify before the United State House of Representatives Committee on Homeland Security, regarding "Leveraging Technology to Improve Homeland Security." The panel testimony is expected to be held at 2 p.m. EST (11 a.m. PST) on Wednesday, July 13, 2005.

The testimony will highlight Rapiscan Systems' airport checkpoint technologies and recent advances in inspection technologies that can improve checkpoint security and passenger flow. Mr. Chopra will discuss the importance of installing new systems at airport checkpoints that increase detection capabilities, fit within current airport infrastructure and facilitate air travel while minimizing inconveniences to the traveling public. The testimony will also highlight four of Rapiscan Systems' technologies:

    * QXR 1000 -- The QXR 1000 integrates Rapiscan's current checkpoint baggage x-ray systems with Quadrupole Resonance technology for automatic explosives detection. The technology's ability to integrate with existing baggage x-ray systems reduces the need to purchase new x-ray machines or hire additional TSA screeners.
    * Secure 1000 -- The Secure 1000, utilizing Rapiscan's patented backscatter technology, is a groundbreaking personnel screening technology that can detect explosives, plastic weapons and any other concealed foreign objects on the body. During the testimony, Mr. Chopra will also discuss some of the findings of the recently completed 6 month pilot program conducted by the British Airport Authority of the Secure 1000 at Heathrow airport in the United Kingdom.
    * Checkpoint Efficiency System (CES) -- The CES easily integrates with current checkpoint x-ray baggage inspection systems to facilitate the flow of passengers through airport checkpoints. The system allows for the continued inspection of passengers and their carry-on items as other passengers and bags are selected for secondary screening.
    * CXR 1000 -- The CXR 1000 is the next-generation of CT hold baggage screening technologies. The system will inspect up to 1,400 bags an hour and can be integrated in-line with the existing airport baggage handling conveyor infrastructure, unlike existing deployed technologies which require the infrastructure to be reconfigured. The CXR 1000 is a solid state CT with no moving gantry.

The testimony will be webcast by the Committee and can be accessed through www.house.gov. A transcript of the testimony will be available either through the Committee website at www.homeland.house.gov or at www.osi-sytems.com.
