American Science and Engineering, Inc. Establishes Marketing and Distribution Channel in China for the ZBV with Nuctech; AS&E to supply ZBV X-ray Sub-Systems to Nuctech Company Limited.

BILLERICA, Mass. -- Continuing to expand the global reach of its proprietary technology, American Science and Engineering, Inc. (NASDAQ: ASEI) (AS&E(R)), a worldwide leader in X-ray detection technology, announced today a marketing and distribution partnership in China with Nuctech Company Limited (Nuctech), a worldwide leading research and development enterprise and manufacturer of cargo X-ray inspection systems, for the Z(R) Backscatter Van(TM) (ZBV). In addition to acting as a value added reseller, Nuctech will supply parts, training, warranty and service and support for the ZBV. The partnership will enable AS&E access into the Chinese security inspection market.

The agreement provides for Nuctech to integrate a pre-assembled X-ray sub-system of AS&E's Z Backscatter Van (ZBV) into a local vehicle chassis for distribution to Chinese customers. The X-ray sub-system will include AS&E proprietary software. AS&E has also received the first order from Nuctech for the ZBV X-ray sub-system.

"This agreement offers AS&E a significant opportunity to bring our proprietary ZBV into the world's fastest growing market," said Anthony Fabiano, President and CEO. "Our new partner, Nuctech, with its reputation for delivering high-quality X-ray detection systems, will open up key distribution channels in China for the ZBV. The first order for the ZBV X-ray sub-system initiates this strategic alliance -- another important step for the ZBV's recognition in the world marketplace."

Fabiano continued, "In advance of this agreement, AS&E has filed for patents in China for AS&E's proprietary technology -- a move that is consistent with our strategy to secure protection for our critical Intellectual Property internationally as well as domestically. We look forward to working closely with our colleagues at Nuctech to make the sale of the ZBV in China a mutually successful business venture."

A breakthrough in X-ray detection technology, AS&E's Z Backscatter Van 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.
