On February 28, 2008, Argon ST, Inc. and its subsidiaries (collectively, the "Company") entered into the Sixth Amendment to Second Amended and Restated Financing and Security Agreement (the "Agreement") with Bank of America, N.A. (the "Lender"), which replaces the Fifth Amendment to Second Amended and Restated Financing and Security Agreement dated as of March 31, 2006. The terms and conditions are substantially similar to the credit facility it replaced. The facility remains at $40 million and contains a sublimit $15 million to cover letters of credit. The interest charged on borrowings under the revolving credit agreement will continue to bear interest at the LIBOR rate plus 150 basis points. In addition, the Company is required to pay, quarterly in arrears, a fee of 0.25 percent per annum on the average daily unused portion of the commitment under this Agreement. The revolving credit agreement will terminate no later than February 28, 2010.

All borrowings under the line of credit are collateralized by all tangible assets of the Company. This Agreement includes customary restrictions regarding additional indebtedness, business operations, permitted acquisitions, liens, guaranties, and transfers and sales of assets, as well as maintaining its primary accounts with the Lender. The Agreement also requires the Company to comply with a specific EBITDA to Funded Debt ratio of not more than 1.50 to 1.00. The Company is currently in compliance and intends to maintain compliance with these covenants and financial ratio. The Agreement contains customary events of default which would permit the Lender to accelerate repayment of borrowings under the Agreement if not cured within applicable grace periods, including the failure to make timely payments under the Agreement or failure to satisfy covenants.

The foregoing description of the provisions of the Agreement is qualified in its entirety by reference to the full and complete terms of the Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein.

The information set forth above under Item 1.01 is hereby incorporated by reference into this Item 2.03

Exhibit 10.1 Sixth Amendment to Second Amended and Restated Financing and Security Agreement
