Varo Corp. said it will consider a sweetened takeover bid from United Scientific Holdings PLC, which already owns 9% of Varo. United Scientific, a British defense company, increased its offer from $17.50 to $22 a share, or about $90.1 million for Garland, Tex.-based Varo. The board of Varo, a maker of night vision systems such as goggles and tank sights for the defense industry, will take up the offer at a meeting to be scheduled.
