Item 8.01 Other Events.

On December 29, 2006, Victor F. Sellier, Vice President, Chief Financial Officer and a Director of Argon ST, Inc. (the "Company") entered into a written sales plan pursuant the guidance specified by Rule 10b5-1 under the Securities Exchange Act of 1934. This plan has been approved pursuant to the terms of the Company's trading policies and procedures. Mr. Sellier's plan is a component of his overall tax and financial planning to provide him enhanced diversification and liquidity.

Rule 10b5-1 enables corporate officers and directors to establish stock trading plans for the orderly sale of predetermined amounts of securities. Such plans may be initiated only when the officers and directors are not in possession of material and non-public information. The rule allows individuals adopting such plans to sell shares over a predetermined period of time, at specific predetermined prices in the future, even if subsequent material and non-public information becomes available to them.

Mr. Sellier's plan is effective January 2, 2007, and provides for the sale of a maximum of 300,000 shares of Argon ST common stock (representing less than 12% of his total Argon ST holdings) in the subsequent nine month period.
