Item 8.01 Other Events.

On January 26, 2010, the Naval Air Warfare Center Aircraft Division (“NAVAIR”) awarded Argon ST, Inc. a non-competitive contract to provide twenty-eight ground surveillance units and associated spares for deployment in support of operational forces abroad. The award was justified as non-competitive based upon a statutory exception for urgent needs. As previously disclosed, the contract is the subject of a bid protest, an administrative proceeding before the Government Accountability Office (“GAO”). Prior to resolution of the protest by GAO, on March 1, 2010, NAVAIR decided to take corrective action to resolve the protest by terminating the contract for convenience, because of NAVAIR’s subsequent determination that more than one source for the units exists. NAVAIR has requested that GAO therefore dismiss the protest. The Navy anticipates that the Department of the Army will rapidly develop a specification for the units and conduct a competition. We intend to submit a proposal in response to the Army’s solicitation when it is released. We will also submit a claim, as is allowed by law, for costs under the current contract which were incurred prior to or as a result of termination.
