Item 1.01  Entry into a Material Definitive Agreement

     The discussion under Item 5.02 below is incorporated herein by reference.

Item 5.02  Departure of Directors or Certain Officers; Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

     On May 20, 2008, pursuant to an agreement (the "Agreement") by and among
Unisys Corporation (the "Company"), on the one hand, and MMI Investments, L.P.,
MCM Capital Management, LLC, Clay B. Lifflander and Charles B. McQuade
(collectively, the "MMI Group") on the other hand, the Company increased the
size of its board of directors (the "Board") to thirteen members, and
appointed, effective immediately, Mr. Lifflander, President of MMI Investments,
L.P.,  to the class of directors serving until the Company's 2008 annual
meeting of stockholders (the "Annual Meeting"), and Mr. McQuade, Retired
Chairman and Chief Executive Officer of Securities Industry Automation Corp.,
to the class of directors serving until the Company's 2010 annual meeting of
stockholders.  Under the Agreement, the Board will nominate Mr. Lifflander for
election to the Board at the Annual Meeting.

     Pursuant to the Agreement, Mr. McQuade will be appointed to the
Board's Compensation Committee and Finance Committee, and Mr. Lifflander to the
Board's Nominating and Corporate Governance Committee and Finance Committee
immediately following the Annual Meeting.

     The parties have further agreed that, until the later of September 15,
2008 or the date on which Mr. Lifflander (or any replacement of Mr. Lifflander
appointed, in the event of Mr. Lifflander's resignation, removal, death or
incapacity, in accordance with the terms and conditions set forth in the
Agreement) ceases to be a director of the Company, the MMI Group and its
affiliates will not acquire any voting securities of the Company which would
increase their ownership to more than 20 percent of the outstanding shares of
the Company's common stock, or sell any voting securities of the Company to any
person who would, as a result of such sale, hold more than 10 percent of the
outstanding shares of the Company's common stock (subject to certain specified
exceptions).  The agreement also restricts the MMI Group from, among other
things, engaging in proxy solicitations in an election contest, advancing
stockholder proposals, seeking to call a meeting of stockholders or solicit
consents from stockholders, or seeking to obtain additional representation on
the Board or remove any Board member during the time period described above.

     The Agreement also contains provisions with respect to public
announcements, confidentiality and reimbursement of MMI Group's reasonable,
documented out-of-pocket fees and expenses, up to $125,000, incurred in
connection with the negotiation and execution of the Agreement and other
matters related to the Annual Meeting.

     The foregoing description of the Agreement is qualified in its entirety by
reference to the full text of the Agreement, which is attached as Exhibit 10.1
hereto and incorporated by reference herein.  A press release issued by the
Company regarding these matters is attached as Exhibit 99.1 hereto.

99.1                 Press Release dated May 21, 2008

                     GOVERNANCE AND COOPERATION AGREEMENT

        This Governance and Cooperation Agreement (this "Agreement") is made
and entered into as of May 20, 2008, by and among Unisys Corporation, a
Delaware corporation (the "Company"), and MMI Investments, L.P., a Delaware
limited partnership ("MMI"), MCM Capital Management, LLC, a Delaware limited
liability company, Clay B. Lifflander and Charles B. McQuade (such entities and
natural persons, collectively, the "MMI Group" and each, individually, a
"member" of the MMI Group) which presently are or may be deemed to be members
of a "group" with respect to the beneficial ownership of the common stock of
the Company, par value $.01 per share (the "Common Stock"), pursuant to Rule
13d-5 promulgated by the Securities and Exchange Commission (the "SEC") under
the Securities Exchange Act of 1934, as amended (the "Exchange Act").


                                  RECITALS:

        WHEREAS, the Company and the MMI Group have engaged in various
discussions and communications concerning the Company's business, financial
performance and strategic plans; and

        WHEREAS, the Company and the members of the MMI Group have determined
(i) that the interests of the Company and its stockholders would be best served
at this time by, among other things, providing for the appointment of certain
individuals to the Company's board of directors (the "Board") and (ii) to come
to an agreement with respect to certain matters related to the 2008 annual
meeting of stockholders of the Company (including any adjournment or
postponement thereof, the "2008 Annual Meeting") and certain other matters, as
provided in this Agreement.

        NOW, THEREFORE, in consideration of the foregoing premises and the
mutual covenants and agreements contained herein, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending to be legally bound hereby, agree
as follows:

1. BOARD MATTERS; BOARD APPOINTMENTS; 2008 ANNUAL MEETING; COMMITTEE
APPOINTMENTS.

               (a) The Company agrees to appoint Clay B. Lifflander
("Lifflander") and Charles B. McQuade ("McQuade" and, together with Lifflander,
the "MMI Nominees") to serve as directors of the Board immediately following
execution of this Agreement.  Lifflander will be appointed to the class of
directors to serve until the 2008 Annual Meeting and thereafter, if elected, for
a term of three years expiring at the Company's 2011 annual meeting of
stockholders, and McQuade will be appointed to the class of directors to serve
for a term expiring at the Company's 2010 annual meeting of stockholders. The
term of each MMI Nominee is referred to herein, as applicable, as the "MMI
Nominee Term".  At the 2008 Annual Meeting, the Board agrees to nominate
Lifflander for reelection as a director, recommend that the Company's
shareholders vote to elect Lifflander as a director, will recommend that the
Company's shareholders vote all proxies in favor of his election and will
otherwise use reasonable best efforts to cause the election of Lifflander in
the same manner as any other director nominees of the Board.  The Company will
file a definitive proxy statement with the SEC which includes such information
regarding Lifflander as is required by federal securities laws in connection
with his nomination by the Company.

               (b) Upon the appointment of the MMI Nominees to the Board, the
size of the Board shall be increased to thirteen (13) directors.  Following the
2008 Annual Meeting, the size of the Board shall not be increased in excess of
thirteen (13) directors at any time while Lifflander is on the Board.

               (c) If Lifflander is not elected to the Board at the 2008 Annual
Meeting, (i) the MMI Group shall thereafter be entitled to select a replacement
nominee whom, subject to a determination by the Board's Nominating & Governance
Committee that such individual is qualified, which may not be unreasonably
withheld, the Company or the Board will promptly appoint to the Board to serve
until the Company's 2009 annual meeting of stockholders (the "2009 Annual
Meeting"); and (ii) the Company will nominate any such replacement nominee for
election to the Board at the 2009 Annual Meeting to serve in place of
Lifflander for a term which will expire at the Company's 2011 annual meeting of
stockholders.  Any replacement director appointed pursuant to this Section 1(c)
shall also be referred to as an "MMI Nominee" and the term for which such MMI
Nominee is appointed pursuant to this Section 1(c) shall be referred to as the
such MMI Nominee's "MMI Nominee Term."

               (d) If at any time during the period from the date of this
Agreement until the end of the applicable MMI Nominee Term: (i) there shall
occur a vacancy in the Board seat previously occupied by Lifflander by reason
of his resignation, removal, death or incapacity, then the Company shall take
all necessary action to promptly fill such vacancy with a person proposed by
the MMI Group, subject to a determination by the independent members of the
Board's Nominating and Governance Committee that such individual is qualified,
which may not be unreasonably withheld; provided that the MMI Group may choose
not to fill such vacancy; or (ii) there shall occur a vacancy in the Board seat
previously occupied by McQuade by reason of his resignation, removal, death or
incapacity, then the Company shall take all necessary action to promptly fill
such vacancy with a person proposed by the MMI Group, subject to a
determination by the independent members of the Board's Nominating and
Governance Committee that such individual is qualified; provided that if the
independent members of the Board's Nominating and Governance Committee
determine that such individual is not qualified, the MMI Group shall propose
three other individuals to fill such vacancy that MMI believes are qualified
and the Company shall appoint one of such three individuals to serve as a
replacement director.  Any replacement director appointed pursuant to this
Section 1(d) shall be appointed for the applicable MMI Nominee Term of the MMI
Nominee replaced and shall also be referred to as an "MMI Nominee."

               (e) The 2008 Annual Meeting shall be held on July 24, 2008, or
within 30 days thereafter. The 2009 Annual Meeting shall be held no later than
June 1, 2009.

               (f) Immediately following the 2008 Annual Meeting, the Board
will appoint McQuade to the Board's Compensation Committee and Finance Committee
and Lifflander to the Board's Finance Committee and Nominating and Governance
Committee, and the Board will appoint an MMI Nominee to each committee of the
Board created after the date of this Agreement, as and when requested by the
MMI Group.  In addition, in the event the powers of the Board's Audit Committee
are expanded after the date of this Agreement in any material respect, the
Board will appoint an MMI Nominee to the Audit Committee, as and when requested
by the MMI Group

               (g) As used in this Agreement, the terms "Affiliate" and
"Associate" shall have the respective meanings set forth in Rule 12b-2
promulgated by the SEC under the Exchange Act; the terms "beneficial owner" and
"beneficial ownership" shall have the respective meanings as set forth in Rule
13d-3 promulgated by the SEC under the Exchange Act; and the terms "person" or
"persons" shall mean any individual, corporation (including not-for-profit),
general or limited partnership, limited liability company, joint venture,
estate, trust, association, organization or other entity of any kind or nature.

               (h) At any meeting of the Company's stockholders taking place
while Lifflander (or any replacement of Lifflander appointed pursuant to
Section 1(d) hereof) is on the Board, MMI shall, and shall cause each of its
Associates and Affiliates to, be present for quorum purposes and to vote all
shares of Common Stock that such person is entitled to vote as of the record
date for such meeting of stockholders (a) in favor of each director nominated
or recommended by the Board for election at such meeting and (b) against any
shareholder nominations for director which are not approved and recommended by
the Board for election at such meeting.

2. STANDSTILL.  For a period commencing upon the date hereof and ending on the
later of (i) the date Lifflander (or any replacement of Lifflander appointed
pursuant to Section 1(d) hereof) shall cease to be a director of the Company
and (ii) September 15, 2008, no member of the MMI Group nor any of its
Affiliates, without the prior written consent of the Board, will, directly or
indirectly, do any of the following provided that this Section 2 shall not
limit any member of the MMI Group from non-public communications with the Board

13(d)(3) of the Exchange Act), through swap or hedging transactions or
otherwise, any voting securities of the Company or any voting rights decoupled

outstanding shares of Common Stock; provided that nothing in this Section 2(b)
shall restrict any member of the MMI Group from engaging in open market

acknowledge that they, as well as their Representatives, are aware that the

the other's officers or directors.

7. SPECIFIC PERFORMANCE.  Each of the members of the MMI Group, on the one
hand, and the Company, on the other hand, acknowledges and agrees that
irreparable injury to the other party hereto would occur in the event any of
the provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached and that such injury would not be
adequately compensable in damages.  It is accordingly agreed that the members
of the MMI Group or any of them, on the one hand, and the Company, on the other
hand (the "Moving Party"), shall each be entitled to specific enforcement of,
and injunctive relief to prevent any violation of, the terms hereof, and the
other party hereto will not take action, directly or indirectly, in opposition
to the Moving Party seeking such relief on the grounds that any other remedy or
relief is available at law or in equity.

8. EXPENSES.  The Company shall reimburse the MMI Group for its reasonable,
documented out-of-pocket fees and expenses incurred (including legal expenses)
in connection with its Schedule 13D, matters related to the 2008 Annual Meeting
and the negotiation and execution of this Agreement, provided that such
reimbursement shall not exceed $125,000 in the aggregate.
9. SEVERABILITY.  If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated. It is hereby stipulated and
declared to be the intention of the parties that the parties would have
executed the remaining terms, provisions, covenants and restrictions without
including any of such which may be hereafter declared invalid, void or
unenforceable. In addition, the parties agree to use their best efforts to
agree upon and substitute a valid and enforceable term, provision, covenant or
restriction for any of such that is held invalid, void or unenforceable by a
court of competent jurisdiction.

obligations arising hereunder brought by the other party hereto or its
successors or assigns, shall be brought and determined exclusively in the

understood that all parties need not sign the same counterpart. In the event
that any signature to this Agreement or any amendment hereto is delivered by
facsimile transmission or by e-mail delivery of a ".pdf" format data file, such
signature shall create a valid and binding obligation of the party executing

respective successors or assigns.  No failure on the part of any party to
exercise, and no delay in exercising, any right, power or remedy hereunder

exercise thereof or the exercise of any other right, power or remedy.  All
remedies hereunder are cumulative and are not exclusive of any other remedies
provided by law.  The terms and conditions of this Agreement shall be binding
upon, inure to the benefit of, and be enforceable by the parties hereto and

UNISYS ADDS NEW DIRECTORS

BLUE BELL, Pa., May 21, 2008 - Unisys Corporation (NYSE: UIS) announced today
that it is expanding its Board of Directors from eleven to thirteen members to
include Clay B. Lifflander, President of MMI Investments, L.P., and Charles B.
McQuade, Retired Chairman and Chief Executive Officer of Securities Industry
Automation Corp.  MMI Investments, L.P., which owns approximately 9.1 percent
of the company's shares, is one of the company's largest shareholders.

"The Board is committed to enhancing value for our shareholders, and is pleased
to welcome Clay and Charles as directors," said Ric Duques, Unisys Chairman.
"The Board and management will benefit from their experience and guidance as we
continue to drive to enhance shareholder value."

Clay Lifflander said "We are firm believers that there is significant,
unrealized value in Unisys.  We are excited to work with the other members of
the Board and look forward to combining our efforts to improve Unisys
performance."

As previously announced, the company is working with its investment bankers to
help the Board explore certain portfolio rationalization and other actions to
enhance shareholder value.  Unisys has recently retained Goldman Sachs to
assist in this exploration.   There can be no assurance that any such
transaction will be pursued or consummated.

Clay Lifflander has been the President of Millbrook Capital Management, Inc.
and MMI Investments, L.P. since their inceptions in 1995 and 1996, respectively.
Previously he served as president of the New York City Economic Development
Corporation under then Mayor Rudolph Giuliani and as managing director in the
M&A Group at Smith Barney.  He served as chief executive officer of Key
Components LLC from 1995 to 2003 and currently serves on the Board of the
Hudson River Museum.  He is a former director of Dendrite International, Inc.,
Key Components and the United Nations Development Corporation.

Charles B. McQuade retired in 2002 from the position of Chairman and Chief
Executive Officer of Securities Industry Automation Corp. (SIAC) (now wholly
owned by NYSE Euronext) after more than 20 years of service as CEO.  He was a
member of the Board of Directors of Greenpoint Financial from 1992 until its
acquisition by North Fork Bank in 2002, and a member of the Board of Directors
of Gartner, Inc from 1999 through 2000.  He has served on numerous industry and
educational advisory boards.

Unisys also announced that it has entered into an agreement with MMI Investments
which provides for certain arrangements between Unisys and MMI, including the
appointment of the two new directors and MMI's agreement to work cooperatively
with the company.
