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 the US Army’s TACOM Life Cycle Management Command (“TACOM LCMC”) has awarded a $5.1 million order for C2A1 filter canisters to the Company. This order serves as a follow-on to the US Army’s initial purchase, valued at more than $2.5 million. TVI expects to fulfill the new order by the end of 2008. “This substantial follow-on order from TACOM, which is more than double the original, reflects the confidence the military has in our ability to produce mission-critical, lifesaving equipment,” said Lt. General Harley Hughes, President and CEO of TVI Corporation. “The C2A1 canister serves as the standard negative pressure filter canister for US Army soldiers in harm’s way and we are proud to play such an important role in serving and protecting them.” “In addition to validating the capabilities of our filter canister operation, this order illustrates the successful execution of our turnaround plan,” Hughes added. “With the C2A1 filter canister, we entered a new market with a new product and are now beginning to be rewarded for our efforts. We view the order as a prime example of our continued efforts to return TVI Corporation to profitable operations.” 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.
