Glenn Dale, MD – April 7, 2009 – TVI Corporation (NASDAQ: TVIN), an international supplier of military and civilian emergency first responder and first receiver products, personal protection products and quick-erect shelter systems, today announced that it was notified by The NASDAQ Stock Market on April 1, 2009 that NASDAQ will suspend and delist trading of the Company’s common stock on the NASDAQ Stock Market, effective at the opening of business on April 13, 2009 in accordance with NASDAQ Marketplace Rules 4300 and IM-4300. The notification also stated that NASDAQ will file a Form 25-NSE with the Securities and Exchange Commission to remove the Company’s securities from listing and registration on The NASDAQ Stock Market.

NASDAQ provided the following reasons for the delisting of TVI’s common stock: (i) the Company’s filing of voluntary bankruptcy petitions seeking relief under the provisions of Chapter 11 of the United States Bankruptcy Code, (ii) concerns regarding the residual equity interest of the existing listed securities holders, and (iii) concerns about the Company’s ability to sustain compliance with all requirements for continued listing on The NASDAQ Stock Market.
