* V-One, a Germantown network security company, lost $717,736 (6 cents a share) on $519,012 in revenue during the second quarter, compared with a loss of $26,235 (1 cent) on $1.2 million in revenue during the same period last year. During the six months ended June 30, the company lost $1.7 million (14 cents) on $1.2 million in revenue, compared with a loss of $378,833 (5 cents) on $2.2 million in revenue during the same period last year. The company attributed its losses to delays in large government contracting programs. In May the company announced that SteelCloud had agreed to acquire V-One. The two companies revised the terms of the merger yesterday, agreeing to an all-stock transaction that guarantees V-One shareholders one SteelCloud common share plus one SteelCloud warrant for every 21 shares of V-One common stock. Under the initial terms of the May 19 letter of intent, common shareholders would have received one share of SteelCloud common stock in exchange for 8.5 shares of V-One common stock. The renegotiation takes into consideration V-One's recent losses and possible additional delays in V-One's government programs.
