Item 4.01. Changes in Registrant's Certifying Accountant. (a) Dismissal of Ernst & Young LLP On March 14, 2008, the Audit Committee of the Board of Directors of Unisys Corporation (the "Company") dismissed Ernst & Young LLP ("Ernst & Young") as the Company's independent registered public accounting firm. The audit reports of Ernst & Young on the consolidated financial statements of the Company for the years ended December 31, 2007 and 2006 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the Company's two most recent fiscal years ended December 31, 2007 and 2006 and from January 1, 2008 through March 14, 2008, there were no disagreements with Ernst & Young on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Ernst & Young's satisfaction, would have caused Ernst & Young to make reference to the subject matter of such disagreements in connection with its reports on the financial statements for such periods. During the Company's two most recent fiscal years ended December 31, 2007 and 2006 and from January 1, 2008 through March 14, 2008, there were no reportable events (as defined in Regulation S-K Item 304 (a)(1)(v)), except that as of December 31, 2007,the Company's internal control over financial reporting was not effective due to the existence of a material weakness as more fully described in Item 9A of the Company's Annual Report on Form 10-K for the year ended December 31, 2007. The Company concluded that a material weakness in internal control over financial reporting existed related to its control environment because the Company did not have a sufficient number of personnel with an appropriate level of U.S. GAAP knowledge and experience commensurate with its financial reporting requirements. The Company is currently in the process of remediating this material weakness. The Company has authorized Ernst & Young to respond fully to inquiries of the Company's new independent registered public accounting firm concerning the material weakness. The Company has provided Ernst & Young with a copy of this Form 8-K prior to its filing with the Securities and Exchange Commission ("SEC"). The Company requested Ernst & Young to furnish the Company with a letter addressed to the SEC stating whether or not it agrees with the above statements. A copy of Ernst & Young's letter, dated March 20, 2008, is attached hereto as Exhibit 16 to this Form 8-K. (b) Engagement of KPMG LLP On March 19, 2008, the Audit Committee engaged KPMG LLP ("KPMG") as the independent registered public accounting firm to audit the Company's financial statements for the fiscal year ending December 31, 2008. The Company did not, nor did anyone on its behalf, consult KPMG during the Company's two most recent fiscal years and any subsequent interim period prior to the Company's engagement of that firm regarding the application of accounting principles to a specified transaction (completed or proposed), the type of audit opinion that might be rendered on the Company's financial statements, any matter being the subject of disagreement or "reportable event" or any other matter as defined in Regulation S-K, Item 304 (a)(1)(iv) or (a)(1)(v).

Gentlemen:

We have read Item 4.01 of Form 8-K dated March 20, 2008 of Unisys Corporation
and are in agreement with the statements contained in the paragraphs 2, 3 and
5. We have no basis to agree or disagree with other statements of the
registrant contained therein.

With respect to paragraph 6 we have no basis to agree or disagree.  However, we
understand that on two separate occasions senior executives of the Company met
with representatives of KPMG LLP, including KPMG LLP's National Office, in the
fall of 2007 to discuss revenue recognition matters.

Regarding the registrant's statement concerning the lack of internal control to
prepare financial statements, included in the third paragraph therein, we had
considered such matter in determining the nature, timing and extent of
procedures performed in our audit of the registrant's 2007 financial statements.


/s/ Ernst & Young LLP
