Greetings! Material Technologies, Inc. (OTC BB: MTNA) MTNA's profile at www.WallStreetCorner.com has been updated. I have been covering its progress in editorials since May 1990. It went through a long process of development, including R, acquisition of additional related technologies, a series of U.S. Government development grants for specific applications of its technology. I feel this is now a Turn-Around. This is one of the uniquely attractive situations that I have investigated. I sincerely believe it has the type of appreciation potential that Intel, Microsoft, Xerox, IBM, similar situations had when they were just past their R phase entering their new huge markets. MTNA is in that same category in my opinion.

Background: MTNA's Electrochemical Fatigue Sensor (EFS) is the only nondestructive testing technology that can find growing cracks in metals, cracks below the surface, as small as 0.010 inches. This critical information allows bridge engineers to fix the specific bridges in most need of repair, verify that repairs are effective in halting further fatigue crack growth by determining that previously found fatigue cracks, which were repaired, are no longer growing. By prioritizing needed repairs using EFS, significant cost savings can be realized, the most critical bridges can be repaired sooner, thereby eliminating bridge postings (restricting the weights of some trucks) minimizing adverse economic impacts.

My Opinion This situation has huge long-term appreciation potential. It's one that you should look into before the investing public becomes aware of what it can in our opinion will do. Most investors who base their opinion of a company on its past performance will miss out on this opportunity, just as they would have done had they used that logic in looking at Microsoft Intel when those companies were at the same early stage as MTNA is now. I like the fact that MTNA's proprietary non-destructive testing technology allows structural engineers to isolate 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. MTNA has exclusive rights to seven patents along with $8.3 million in already completed contracts from the U.S. Government for research, testing, validation of its innovative solutions. CEO Robert M. Bernstein says: "State bridge engineers are looking for ways to maximize the effectiveness of transportation funding to maintain existing bridge infrastructure. The Transportation Equity Act set aside funds to test devices capable of finding growing cracks in bridges as small as 0.01 inches in length under the surface. Our EFS solution is the only non-destructive testing device able to find cracks that small. Based on what we believe is tremendous potential for market acceptance the highly favorable response we have received so far, we are intensifying our marketing programs to increase awareness, generate additional inquiries, achieve maximum results." I like the fact that MTNA's EFS can accurately test the integrity of not only bridges, but railroads, airplanes, ships, cranes, power plants, mining equipment, piping systems, heavy iron, etc.
