Pasat was charged in connection with the sale of 21 warplanes to the United States in 1997, when he was defense minister.
He was accused of having sold 21 MiG-29s too cheaply at $40 million, causing a loss of $55 million to the state.
His lawyer, Gheorghe Amihalachioae, said the verdict is "not fair" and said he would appeal, including at the European Court of Human Rights.
