On September 29, 2004, a wholly-owned subsidiary of Sensytech, Inc. (“Sensytech”) merged with and into Argon Engineering Associates, Inc. (“Argon Engineering”) in a merger whereby each outstanding share of Argon Engineering common stock was exchanged for two shares of Sensytech common stock. As a result of the merger, the former Argon Engineering stockholders acquired approximately 65.6% of the issued and outstanding shares of Sensytech common stock. In accordance with Statement of Financial Accounting Standards No. 141 “Business Combinations”, the merger was accounted for as a reverse acquisition, whereby Argon Engineering was deemed to have acquired Sensytech for financial reporting purposes. Consistent with the reverse acquisition accounting treatment, the historical financial statements presented for periods prior to the acquisition date are the statements of Argon Engineering except for stockholders’ equity which has been retroactively restated for the equivalent number of shares of the legal acquirer.

The following unaudited condensed pro forma results of operations reflect the pro forma combination of Argon Engineering and Sensytech as if the combination had occurred at the beginning of the period presented, compared with the actual results of operations of Argon Engineering for the same period.
