Los Angeles, CA - April 13, 2007 -- In February, 2007 Material Technologies, Inc. (OTC BB; MTTG.OB - News) ("MATECH" or "the Company") was invited to discuss its revolutionary metal fatigue detection solutions with executives of Network Rail in London, England. At that time, renowned infrastructure engineering expert Dr. Brent Phares, PE discussed the technical and economic advantages of implementing MATECH's Electrochemical Fatigue Sensor™ (EFS) inspection system on a variety of railway assets. That February 2007 meeting was a follow-up to an earlier introduction of MATECH's fatigue detection capabilities at the 24th International Exhibition of Railtrack Technology in Munster/Westfalen, Germany last May.

Network Rail is the British equivalent of the Association of American Railroads and the Federal Railroad Administration in the U.S.; as with railroads in the United States, Network Rail is concerned about fatigue damage and interested in fatigue crack detection on critical components of their railway systems.

Since the meeting in February, Network Rail has been working on preparing to contract with MATECH to inspect several bridges.  Successful completion of these initial inspections is expected to lead to a recurring contract with MATECH.

"Railways are an ideal application for our metal fatigue detection solutions because of their constant cycles of heavy loading," said MATECH CEO Robert M. Bernstein. "Our EFS technology is the only nondestructive testing solution capable of finding growing cracks in metals as small as 0.01 inches-critical information that can help railroad engineers ensure safety, prioritize repairs and reduce costs."

MATECH's proprietary EFS inspection system can satisfy new welded rail safety requirements set forth by the $286 billion U.S. Transportation Bill, known as SAFETEA-LU, signed into law in late 2005. The legislation requires, among others, each railway track operator using continuous welded rail track to include procedures to improve the identification of cracks as well as improve the methods of inspection of joint bars in continuous welded rail.

About Material Technologies, Inc. (MTTG.OB)

MATECH is an engineering, research and development company specializing in technologies to measure microscopic fractures and flaws in metal structures and monitor metal fatigue in real time. The company’s leading edge metal fatigue detection, measurement and monitoring solutions can accurately test the integrity of metal structures and equipment including bridges, railroads, airplanes, ships, cranes, power plants, mining equipment, piping systems and heavy iron.

MATECH owns the only non-destructive testing technology able to find growing cracks as minute as 0.01 inches—critical information that allows structural engineers to isolate and repair the more than 100,000 steel bridges in the U.S. which have been classified as structurally deficient or functionally obsolete by the Federal Highway Administration. MATECH has exclusive rights to seven patents along with $8.3 million in already completed contracts from the US Government for research, testing and validation of its innovative solutions.
