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.


     Pursuant to the requirements of the Securities Exchange Act of 1934, the
registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
