GLENN DALE, MD – TVI Corporation (NASDAQ: TVIN), an international supplier of military and civilian emergency first responder and first receiver products, personal protection products, quick-erect shelter systems and event shelter and equipment rentals, today announced that it received a $700,000 order to deliver two Human Remains Affairs systems to the United States Army. TVI expects to fulfill the order in the second quarter of 2008. Fundamentally, these shelters and related equipment serve as mobile mortuaries for use by the military working in remote locations and battlefield environments as well as disaster response teams in situations like the aftermath of Hurricane Katrina. “We believe this contract sets the stage for TVI to expand its shelter expertise to areas beyond the markets we’ve traditionally served,” said Lt. General Harley Hughes, President and CEO of TVI Corporation. “With this system, we have added another product to TVI’s product suite, as we attempt to further diversify our revenue stream, not just within TVI, but within SafetyTech and Signature as well. More importantly, we proved to the Army that we can deliver a better system than our leading competitors in this segment.” “This sale represents an important milestone in our turnaround effort at TVI,” Hughes added. “With it, we’ve shown that we can bring a new product to market and land an early-adopter customer in the face of intense, entrenched competition, all in our continuing program to refill the pipeline, rebuild the backlog and generate profitable, sustainable revenue.” About TVI Corporation TVI Corporation, headquartered in Glenn Dale, Maryland, is an international supplier of military and civilian emergency first responder and first receiver products, personal protection products and quick erect shelter systems.
