American Science and Engineering, Inc. Receives Orders for ZBV and Multiple Gemini Systems from the Middle East; AS&E to Demonstrate its Technology This Week at Trade Show in Dubai.

BILLERICA, Mass. -- American Science and Engineering, Inc. (NASDAQ: ASEI) (AS&E(R)), a leader in X-ray detection technology, announced today the receipt of orders from two Middle Eastern entities for X-ray security systems. The orders include a Z(R) Backscatter Van(TM) (ZBV) and multiple units of the recently introduced Gemini(TM) parcel X-ray inspection system, totaling in excess of $1 million. E[acute accent]"We are experiencing an increased volume of business coming out of the Middle East," said Anthony R. Fabiano, President and CEO of AS&E. "Both of these clients require the highest level of security and these orders demonstrate their commitment to utilize technology to enhance their inspection protocol. With these two new prestigious clients, we continue to expand our install base and develop strong customer relationships in this strategic region." E[acute accent]Fabiano continued, "We are increasing our marketing efforts in the Middle East and this week we are exhibiting and demonstrating our technology at the Airport Build & Supply Show in Dubai. During the show, prospective clients will be able to view live demonstrations of our SmartCheck(TM) personnel screening system. As the industry's most comprehensive personnel X-ray detection system, SmartCheck clearly displays all types of threats concealed under a person's clothing, while ensuring privacy."

E[acute accent]About Gemini(TM)

E[acute accent]Gemini is the first conventional parcel inspection system on the market to combine dual-energy transmission and proprietary Z Backscatter X-rays, allowing operators to obtain the most information about the contents of a parcel. Operators simultaneously view two images, a Z Backscatter image and a dual-energy image, dramatically increasing the likelihood of finding illegal materials hidden in parcels. Gemini's unique capability to detect both metallic and non-metallic threats -- even in cluttered environments -- makes it an invaluable inspection tool for security officials.

E[acute accent]About ZBV

E[acute accent]A breakthrough in X-ray detection technology, AS&E's Z Backscatter Van(TM) is a low-cost, highly mobile screening system built into a commercially available delivery van. The ZBV allows for immediate deployment in response to security threats, and its high throughput capability facilitates rapid inspections. The system's unique "drive-by" capability allows one or two operators to conduct X-ray imaging while the ZBV drives past suspect vehicles and objects. For personnel safety in dangerous environments, a remote console is available for operating the system in stationary mode from a distance of up to 500 meters.

E[acute accent]About SmartCheck(TM)

E[acute accent]AS&E's SmartCheck system is the most effective way to screen for contraband and threats hidden under a person's clothing. Its capability goes well beyond that of metal detectors because it simultaneously detects both metallic and non-metallic objects, such as guns and knives, plastic explosives, composite weapons, drugs and other hidden threats and contraband. And its photo-like Z(R) Backscatter image gives the operator an easy-to-read display of where the threat or contraband is hidden, thus eliminating the need for intrusive and time-consuming pat-down and strip searches. It is easy to use and depending on the operating mode, the system requires only one or two operators. The SmartCheck system is safe for all individuals and complies with all applicable U.S. personnel scanning regulations. An optional privacy filter protects the privacy of screened persons and still effectively displays threats.
