Item 8.01. Other Events Effective May 31, 2006, Unisys Corporation entered into a three-year, secured revolving credit facility. The new credit agreement, which provides for loans and letters of credit up to an aggregate of $275 million, replaces the company's $500 million credit agreement that expired on May 31, 2006. Borrowings under the new facility will bear interest based on short-term rates and the company's credit rating. The credit agreement contains customary representations and warranties, including no material adverse change in the company's business, results of operations or financial condition. It also contains financial covenants requiring the company to maintain certain interest coverage, leverage and asset coverage ratios and a minimum amount of liquidity. Other covenants include covenants limiting liens, mergers, asset sales, dividends and the incurrence of debt. Events of default include non-payment, failure to perform covenants, materially incorrect representations and warranties, change of control and default under other debt aggregating at least $25 million. The facility is secured by the company's assets, except that the collateral does not include accounts receivable that are subject to the company's U.S. trade accounts receivable facility, U.S. real estate or the stock or indebtedness of the company's U.S. operating subsidiaries.
