            (such written notice must detail the action or conduct allegedly
            constituting Good Reason). If Executive fails to give such requisite
            notice, or if UGS timely corrects such alleged breach, the action or
            conduct shall not constitute Good Reason;

                   -----------------------
     voluntary termination of employment pursuant to Section 3.2.1 or the
     termination of Executive's employment by UGS for Cause pursuant to Section
     3.2.3, UGS shall have no further obligation to provide Executive with any

     bonus, or other compensation or benefits accrued to the Termination Date.

            3.3.2  Death and Disability Benefits. In the event of the
                   -----------------------------
     termination of the employment relationship by reason of death or Disability
     pursuant to Section 3.2.5, UGS shall pay Executive his salary to the date
     of his death or decision regarding Disability; and the right of Executive

     applicable death, disability, pension, insurance or other written benefit
     plans or policies.

            3.3.3  Other Termination Benefit Entitlements. Except as otherwise
                   --------------------------------------
     provided in Section 3.4 with respect to Executive's termination in the
     event of a Change of Control, if UGS terminates the employment of Executive
     with notice as set forth in Sections 3.1 or 3.2.2, or Executive terminates

     will be entitled to the following benefits:

                   (a) Full base salary and any bonus or long term incentive
            compensation to which Executive is entitled through the Termination
            Date.

                   (b) A severance payment, less all applicable deductions,
            equal to (i) one times the Executive's annual base salary in effect
            as of the Termination Date plus (ii) an amount equal to the
            Executive's bonus target in effect for the fiscal year in which the
            Termination Date falls, or if a bonus target has not yet been
            established, an amount equal to 1.25 times the Executive's bonus
            target for the previous fiscal year.

                   (c) Notwithstanding any provision to the contrary in any
            applicable award agreement(s), continued vesting of any unvested UGS
            stock options, other UGS stock awards, and EDS Incentive Plan awards
            granted as of the Termination Date in accordance with the vesting
            schedules set forth in the applicable award agreement(s) between the
            Executive and UGS and/or EDS. This Agreement shall be deemed to
            amend any employee award agreement to the extent required to comply
            with this Section 3.3.3(c).

                   (d) A cash payment to pay for twelve (12) months of (i)
            Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA")
            continuation health coverage for the Executive and his family, (ii)
            premiums for basic employee life

                                       5
<PAGE>

            insurance coverage ($50,000), and (iii) premiums for long term
            disability insurance providing income replacement of $7,000 per
            month.

                   (e) Reimbursement not to exceed $75,000 of the costs of
            existing home sale (including payment of any real estate sales
            commission up to six percent of the home sale price) and packing and
            shipping expenses in accordance with Company's then-existing
            household goods shipping policies for employees if within twelve
            (12) months of termination under this Section 3.3.3, Executive
            relocates to a new work location which is more than 35 miles from
            his primary work location on the Termination Date.

                   (f) Reimbursement not to exceed $25,000 for outplacement
            services provided by an outplacement service acceptable to UGS
            within twelve (12) months of termination under this Section 3.3.3.

     3.4    Termination as a Result of a Change of Control.  UGS recognizes that
            ----------------------------------------------
the continuing possibility of a Change of Control of UGS is unsettling to
Executives of the Company. Therefore, the arrangements set forth below are being
made to help assure a continuing dedication by Executive to his duties to the
Company, notwithstanding the occurrence or potential occurrence of a Change in
Control. In particular, UGS believes it important, should the Company receive
proposals or inquiries from third parties with respect to its future, to enable
Executive, without being influenced by uncertainties of his own situation, to
assess and advise the Company whether such proposals would be in the best
interests of the Company and its shareholders and to take such other action
regarding such proposals as the Company might determine to be appropriate.
Accordingly, if between effective date (the "Change of Control Date") of a
Change of Control (as defined below) and 24 months following the Change of
Control Date, UGS gives notice under Section 3.1 that this Agreement will not be
extended for reasons other than Cause, gives notice of termination under Section
3.2.2, or if Executive terminates for Good Reason, UGS shall provide the
Executive with the benefits as set forth below in this Section 3.4.
Notwithstanding any other provision of this Agreement, if a Change in Control
occurs and if the Executive's employment with the Company or any of its
subsidiaries is terminated by the Company less than six months prior to the date
on which the Change in Control occurs, and if it is demonstrated by the
Executive that such termination of employment by the Company (i) was at the
request of a third party which has taken steps reasonably calculated to result
in or effect the Change in Control or (ii) otherwise arose in connection with or
in anticipation of the Change in Control, then for all purposes of this
Agreement, such termination of employment shall be deemed to have occurred
within two years following such Change in Control provided that the obligations
contained in Section 3.1 to deliver a notice of termination shall not apply.
Benefits to which Executive shall be entitled are:

            3.4.1  Full base salary and any bonus or long term incentive
     compensation to which the Executive is entitled through the Termination
     Date.

            3.4.2  A severance payment, less all applicable deductions, equal to
     (i) two times the Executive's annual base salary in effect as of the
     Termination Date plus (ii) an

                                       6
<PAGE>

     amount equal to two times the Executive's bonus target in effect for the
     fiscal year in which the Termination Date falls, or if a bonus target has
     not yet been established, an amount equal to two times the Executive's
     bonus target for the previous fiscal year.

            3.4.3  Notwithstanding any provision to the contrary in any
     applicable award agreement(s), continued vesting of any unvested UGS stock
     options, other UGS stock awards, and EDS Incentive Plan awards granted as
     of the Termination Date in accordance with the vesting schedules set forth
     in the applicable award agreement(s) between the Executive and UGS and/or
     EDS. This Agreement shall be deemed to amend any employee award agreement
     to the extent required to comply with this Section 3.4.3.

            3.4.4  A cash payment to pay for twelve (12) months of (i)
     Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA")
     continuation health coverage for the Executive and his family, (ii)
     premiums for basic employee life insurance coverage ($50,000), and (iii)
     premiums for long term disability insurance providing income replacement of
     $7,000 per month.

            3.4.5  Reimbursement not to exceed $75,000 of the costs of existing
     home sale (including payment of any real estate sales commission up to six
     percent of the home sale price) and packing and shipping expenses in
     accordance with Company's then-existing household goods shipping policies
     for employees if within twelve (12) months of termination under this
     Section 3.4, Executive relocates to a new work location which is more than
     35 miles from his primary work location on the Termination Date.

            3.4.6  Reimbursement not to exceed $25,000 for outplacement services
     provided by an outplacement service acceptable to UGS within twelve (12)
     months of termination under this Section 3.4.

     3.5  Change of Control Conditions Precedent and Definition. No compensation
          -----------------------------------------------------
shall be payable under Section 3.4 unless and until (a) there shall have been a
Change of Control in UGS while the Executive is still an employee of UGS or was
an employee within six (6) months of the Change of Control Date if the second to
the last sentence of Section 3.4 applies and (b) the Executive's employment by
the Company thereafter shall have been terminated in accordance with Sections
3.1, 3.2.2 or 3.2.4. Under this Agreement, "Change of Control" of UGS means a
change in control of the Company occurring after the Effective Date of this
Agreement of a nature that would be required to be reported in response to Item
6(e) of Schedule 14A of Regulation 14A (or in response to any similar item on
any similar schedule or form) under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), whether or not the Company is then subject to such
reporting requirement; provided however, that, without limiting the generality
of the foregoing, a Change in Control shall be deemed to have occurred
(irrespective of the applicability of the initial clause of this definition) if
at any time after the Effective Date (a) any "person" (as such term is used in
Sections 13(d) and 14(d) of the Exchange Act, but excluding (i) any employee
benefit plan of the Company or of any subsidiary of the Company, and (ii) any
entity organized, appointed or established by the Company pursuant to the terms
of any such plan) is or becomes the "beneficial owner" (as defined in Rule 13d-3
under the

                                       7
<PAGE>

Exchange Act), directly or indirectly, of securities of the Company representing
50% or more of the combined voting power of the Company's then outstanding
securities without the prior approval of at least two-thirds of the members of
the whole board in office immediately prior to such person attaining such
percentage interest; (b) the Company is a party to a merger, consolidation,
share exchange, sale of assets or other reorganization, or a proxy contest, as a
consequence of which members of the board in office immediately prior to such
transaction or event constitute less than a majority of the whole board
thereafter; or (c) during any period of two consecutive years, individuals who
at the beginning of such period constituted members of the board (including for
this purpose any new member whose election or nomination for election by the
Company's stockholders was approved by at least two-thirds of the members of the
whole board then still in office who were members of the board at the beginning
of such period) cease for any reason to constitute a majority of the whole
board. Notwithstanding the foregoing, a Change in Control shall not be deemed to
have occurred solely as a result of Electronic Data Systems Corporation (or a
successor corporation) remaining or becoming the beneficial owner of 50% or more
of the combined voting power of the Company's then outstanding securities.

     3.6    Excess Parachute Payment Limit. Notwithstanding anything contained
            ------------------------------
in this Agreement to the contrary, in the event that any payment (within the
meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended
or replaced (the "Code")), or distribution to or for the benefit of the
Executive, whether paid or payable or distributed or distributable pursuant to
the terms of this Agreement or otherwise in connection with, or arising out of,
his or her employment with the Company (a "Payment" or "Payments"), would be
subject to the excise tax imposed by Section 4999 of the Code or any interest or
penalties are incurred by the Executive with respect to such excise tax (such
excise tax, interest and penalties collectively referred to as the "Excise
Tax"), then the amount of Payments under this Agreement, when added to all other
Payments to which Executive is entitled, shall be reduced to one dollar ($1.00)
less than three hundred percent (300%) of Executive's Base Amount (as
hereinafter defined) in accordance with Section 280G of the Code.  For purposes
of this Section, Executive's "Base Amount" is his average annual taxable
compensation received from the Company for the five (5) calendar years (or such
lesser number which comprises the entire number of years of his employment with
the Company) preceding the calendar year in which a change in the ownership or
effective control of the Company or a change in the ownership of a substantial
portion of the Company's assets occurs (within the meaning of Section 280G(b)(2)
of the Code) occurs.

            3.6.1  Excess Parachute Payment Dispute Resolution. UGS shall notify
                   -------------------------------------------
     the Executive in writing within ten (10) days after a notice of termination
     is given by the Company or the Executive, of the amounts of payments to be
     made by UGS under this Agreement, together with any other payments made or
     to be made by the Company to the Executive, that constitute "parachute
     payments" (as such terms are defined in Section 280G of the Internal
     Revenue Code) and the excess payments and of the amount of the reduction,
     if any, required by Section 3.6. Within thirty (30) days after the notice
     of termination is given, the Executive shall notify the Company in writing
     whether or not he agrees with the Company's calculation of the amount of
     parachute payments and excess parachute payments, and the amount of any
     reduction. If the executive does not agree with UGS' calculations, the
     Executive shall inform the Company of the amounts he

                                       8

     believes to be the correct amounts. If UGS and the Executive cannot agree
     within forty five (45) days after the notice of termination is given on the
     amount of parachute payments and excess parachute payments, and on the
     amount of any reduction, the calculation of such amounts (and reduction)
     shall be made by independent tax counsel selected by the Company's
     independent auditors. Such determination shall be completed within fifteen
     (15) days after it is submitted to such independent counsel and shall be
     conclusive and binding on the parties.

     3.7    Net Payments.  Any amounts required to be paid by UGS to Executive
            -------------
under this Section 3 shall be paid net of applicable federal, state and local
tax withholding

            ------------
under this Section 3 shall be paid in cash in a lump sum on the tenth (10th) day
after the Termination Date. If it is later determined, under the procedure set
forth in Section 3.6.1, that the amount of any reduction is less than that
initially determined by UGS, the Company shall pay the difference to the
Executive in cash within five (5) days after the amount of an reduction is
finally determined. If it is later determined, under the procedures set forth in
Section 3.6.1, that the amount of any reduction is more than that initially
determined by UGS, the Executive shall repay the difference to the Company
within five (5) days after the amount of any reduction is finally determined.
