BLUE BELL, Pa., February 28, 2011 – Unisys Corporation (NYSE: UIS) today announced that it has closed its previously announced offering of 2,250,000 shares of its 6.25% Mandatory Convertible Preferred Stock, Series A, at an initial liquidation preference of $100 per share (the “Mandatory Convertible Preferred Stock”).

With the exercise of the over-allotment option, a total of 2,587,500 shares of Mandatory Convertible Preferred Stock were issued in the offering. The offering was made under the company’s existing shelf registration statement filed with the Securities and Exchange Commission.

The company also announced that it is using the net proceeds from the offering to redeem an aggregate of $124.7 million of the company’s 12 ³/4% Senior Secured Notes due 2014 and an aggregate of $86.3 million of the company’s 14 ¹/4% Senior Secured Notes due 2015.

As also previously announced, the company has commenced a cash tender offer in respect of the 12 ³/4% Senior Secured Notes due 2014 and the 14 ¹/4% Senior Secured Notes due 2015, for a maximum aggregate consideration, excluding accrued and unpaid interest, not to exceed $220,000,000.
