Forward-Looking Statements:

Except for the historical information contained herein, the matters
discussed in this press release are forward-looking statements . "In the
bridge industry alone, there are over 100,000 steel bridges that are
structurally impaired , comprising $400 Billion of repair liability,
impending accidents, and potential disruption of commerce . By offering a
product that can more accurately determine structural integrity and does
not require a skilled operator, we are saving engineering authorities time
and money by preventing structural collapse and possible human tragedy."

MATECH is engaged in the research and development of metal fatigue
detection, measurement, and monitoring technologies.

Brent Phares, PE, Marketing Director for Material Technologies, Inc. It
was utilized in tests last year in Ohio, California, Pennsylvania, and New
York to detect active fatigue cracks in highway bridge structures.

The groundbreaking Electrochemical Fatigue Sensor (EFS) can be applied to
virtually any industry in which fatigue of metal is a significant
structural issue: Bridges, Aerospace, Turbine Engines, Oil & Gas,
Construction, Shipping, etc.

"To put it simply, it is the most technologically advanced product of its
kind on the market," said Robert M.

"This technology is capable of locating actively growing cracks, including
below the surface, in metal structures . A remarkable feature is that it can
be used to evaluate the effectiveness of a crack repair with near 100%
accuracy," explained Dr. Phares.

About MATECH

MATECH is an engineering, research and development company that specializes
in technologies to measure the growth of microscopic fractures and flaws in
metal structures and monitor metal fatigue in real time.
Factors that could cause actual results to differ include activity levels
in the securities markets and other risk factors such as customer order
rates, cancellations, late delivery of customer components, late system
delivery , production delays, dependence upon certain customers,
dependencies upon key executives, competition , product liability risk,
control by management, development of new competing technology, and other
risks detailed in the applicable U.

Dr. Thus far, EFS techniques
have been used in New York, Ohio, California, and Pennsylvania to check for
cracks in welded joints, weld toes and surface cracks. The company holds
exclusive rights to seven patents in this important field and has developed
a suite of devices for the non-destructive evaluation of fatigue in metals
including the Electrochemical Fatigue Sensor (EFS) technique.
