                ----------------------------------
     employment with UGS at any time for any reason whatsoever by giving 60
     days' written notice to UGS. Upon Executive giving the requisite notice of
     his intent to terminate his employment, the Company, at its sole
     discretion, shall have the option of immediately accepting Executive's
     resignation. Upon accepting Executive's resignation, the Company shall have

     notice to Executive. In lieu of providing Executive with 60 days' written
     notice, the Company shall have the sole discretion to immediately terminate

          3.2.3 Termination for Cause. UGS may terminate Executive's employment
                ----------------------
     at any time for Cause, with or without notice. For purposes of this
     Section, the term "Cause" shall mean (a) gross or habitual neglect of
     duties or misconduct in the performance of the duties and services required
     of Executive pursuant to this Agreement; (b) conduct of Executive which is
     materially detrimental to UGS' reputation or business operations or its
     ability to secure or renew future contracts; (c) Executive's conviction of
     a felony or of a misdemeanor involving moral turpitude; (d) Executive's
     breach of a material provision of this Agreement which remains uncorrected
     for 30 days following written notice to the Executive by UGS of such
     breach; (e) continued failure or refusal of Executive to faithfully,
     diligently and competently perform the usual and customary duties of his
     employment; or (f) failure or refusal of Executive to materially comply

     his employment with UGS at any time for Good Reason. The term "Good Reason"
     shall mean:

               (a) a material breach of a material provision of this Agreement
          by the Company which breach remains uncorrected for 30 days following
          written notice to UGS by Executive of such breach (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;

               (b) a reduction by UGS in Executive's base salary as in effect on
          the Effective Date by more than twenty five percent (25%);

               (c) Executive's ineligibility to participate in bonus and/or
          compensation programs (excluding those described in Paragraph 2.4) in
          which other similarly situated Executives are eligible to participate;

               (d) failure by the Company to provide Executive with benefits
          (e.g., life insurance, medical, dental, accident, and disability) that
          are available to other similarly situated executives;

               (e) if a Change of Control occurs, the Company's requiring
          Executive to be based at any office or location more than thirty five
          (35) miles from the location at which he was based prior to the Change
          of Control, except for travel reasonably required in the performance
          of the Executive's responsibilities; or

               (f) any failure by UGS to obtain the assumption of this Agreement
          by any successor or assign of UGS.

          3.2.5 Termination Upon Death or Incapacity. Executive's employment
                -------------------------------------
     will also terminate immediately upon Executive's death or Disability. For
     purposes of this Agreement, "Disability" shall mean the inability of the
     Executive to perform his duties on a full-time basis for 180 consecutive
     business days as a result of incapacity due to mental or physical illness
     which is determined to be total and permanent by a physician selected by
     the Company or its insurers and acceptable to Executive or Executive's
     legal representative (such agreement as to acceptability is not to be
     withheld unreasonably).

     3.3 Effects of Termination. The effects of termination of the employment
         -----------------------
relationship shall be as follows:

          3.3.1 Termination of Benefits. In the event of Executive's 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 benefits
     and/or payments, except as required by law or the terms of a controlling
     benefit or stock plan or policy and the payment of any salary, 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 or Executive's
     heirs to

                                  Page 3 of 9
<PAGE>

     compensation thereafter shall be governed by the 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
     the employment relationship for Good Reason under Section 3.2.4, Executive
     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 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

                                  Page 4 of 9
<PAGE>

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 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 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

                                  Page 5 of 9
<PAGE>

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 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

     3.8 Payment Date. Any amounts required to be paid by UGS to Executive 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.

Section 4. Executive's Non-Competition and Non-Solicitation Obligations
           ------------------------------------------------------------
