                                  RONALD L. TURNER
                                   ("EXECUTIVE")
 
 
DATE:     OCTOBER 1, 1999
 
RECITALS
 
A.     Ceridian wishes to obtain the services of Executive for the duration of
       this Agreement, and Executive wishes to provide his or her services for
       such period.
 
B.     Ceridian desires reasonable protection of Ceridian's Confidential
       Information (as defined below).
 
C.     Ceridian desires assurance that Executive will not compete with Ceridian,
       engage in recruitment of Ceridian's employees or make disparaging
       statements about Ceridian after termination of employment, and Executive
       is willing to refrain from such competition, recruitment and
       disparagement.
 
D.     Executive desires to be assured of a minimum Base Salary (as defined
       below) from Ceridian for Executive's services for the term of this
       Agreement (unless terminated earlier pursuant to the terms of this
       Agreement).
 
E.     It is expressly recognized by the parties that Executive's acceptance of,
       and continuance in, Executive's position with Ceridian and agreement to
       be bound by the terms of this Agreement represents a substantial
       commitment to Ceridian in terms of Executive's personal and professional
       career and a foregoing of present and future career options by Executive,
       for all of which Ceridian receives substantial value.
 
F.     The parties recognize that a Change of Control (as defined below) may
       result in material alteration or diminishment of Executive's position and
       responsibilities and substantially
 
 
                                       1
 
 
<PAGE>
 
 
       frustrate the purpose of Executive's commitment to Ceridian and
       forebearance of career options.
 
G.     The parties recognize that in light of the above-described commitment and
       forebearance of career options, it is essential that, for the benefit of
       Ceridian and its stockholders, provision be made for a Change of Control
       Termination (as defined below) in order to enable Executive to accept and
       effectively continue in Executive's position in the face of inherently
       disruptive circumstances arising from the possibility of a Change of
       Control of the Parent Corporation (as defined below), although no such
       change is now contemplated or foreseen.
 
H.     The parties wish to replace any and all prior agreements and undertakings
       with respect to Executive's employment and Change of Control occurrences
       and compensation.
 
NOW, THEREFORE, in consideration of Executive's acceptance of and continuance in
Executive's employment for the term of this Agreement and the parties' agreement
to be bound by the terms contained herein, the parties agree as follows:

                                     ARTICLE IV
 
                                 EARLY TERMINATION
 
4.01   EARLY TERMINATION.  This Article shall not apply to a Change of Control
       Termination which is governed solely by the provisions of Article VII,
       and does not alter the respective continuing obligations of the parties
       pursuant to Articles V, VI, and IX.
 
4.02   TERMINATION FOR CAUSE.  Ceridian may terminate this Agreement and
       Executive's employment immediately for cause.  For the purpose hereof
       "cause" means:
 
       (a)    fraud;
 
       (b)    misrepresentation;
 
       (c)    theft or embezzlement of Ceridian assets;
 
       (d)    intentional violations of law involving moral turpitude;
 
       (e)    failure to follow Ceridian's conduct and ethics policies; and/or
 
       (f)    the continued failure by Executive to attempt in good faith to
              perform his or her duties as reasonably assigned to Executive
              pursuant to Section 2.02 of Article II of this Agreement for a
              period of 60 days after a written demand for such performance
              which specifically identifies the manner in which it is alleged
              Executive has not attempted in good faith to perform such duties.
 
       In the event of termination for cause pursuant to this Section 4.02,
       Executive shall be paid at the usual rate of Executive's annual Base
       Salary through the date of termination specified in any written notice of
       termination.
 
4.03   TERMINATION WITHOUT CAUSE.  Either Executive or Ceridian may terminate
       this Agreement and Executive's employment without cause on at least 75
       days' written notice.  In the event of termination of this Agreement and
       of Executive's employment pursuant to this Section 4.03, compensation
       shall be paid as follows:
 
       (a)    if the notice of termination is given by Executive, Executive
              shall be paid at the usual rate of his or her annual Base Salary
              through the 75 day notice period;
 
       (b)    if the notice of termination is given by Ceridian, (1) Executive
              shall be paid at the usual rate of his or her annual Base Salary
              through the 75 day notice period, however, Ceridian shall have the
              option of making termination of the Agreement and Executive's
              employment effective immediately upon notice in which case
              Executive shall be paid a lump sum representing the value of 75
              days worth of salary; and (2) Executive shall receive, starting
              within 15 days after the end of the
 
 
                                       5
 
<PAGE>
 
 
              75 day notice period, two year's Base Salary payable, at the sole
              discretion of Ceridian, in either the form of a lump sum payment
              or on a regular payroll period basis.  In addition, Executive
              shall receive the bonus, if any, to which Executive would
              otherwise have become entitled under all applicable Ceridian bonus
              plans in effect at the time of termination of this Agreement had
              Executive remained continuously employed for the full fiscal year
              in which termination occurred and continued to perform his or
              her duties in the same manner as they were performed immediately
              prior to termination, multiplied by a fraction, the numerator of
              which shall be the number of whole months Executive was employed
              in the year in which termination occurred and the denominator of
              which is 12. This bonus amount shall be paid within 15 days
              after the date such bonus would have been paid had Executive
              remained employed for the full fiscal year.  In addition,
              Ceridian shall provide or make arrangements for reasonable
              outplacement services for Executive based on his or her level
              within Ceridian.
 
       (c)    In the event that termination occurs pursuant to Section 4.03(b),
              in addition to the payments specified therein, Ceridian shall pay
              to Executive an amount equal to one year's Base Salary payable, at
              the sole discretion of Ceridian, in either the form of a lump sum
              payment or on a regular payroll period basis, provided Executive
              executes a release, similar to that attached as Exhibit A, of all
              claims against Ceridian.
 
4.04   TERMINATION IN THE EVENT OF DEATH OR DISABILITY.  This Agreement shall
       terminate in the event of death or disability of Executive.
 
       (a)    In the event of Executive's death, Ceridian shall pay an amount
              equal to 12 months of Base Salary at the rate in effect at the
              time of Executive's death plus the amount Executive would have
              received in annual incentive plan bonus for the year in which the
              death occurs had "target" goals been achieved.  Such amount shall
              be paid (1) to the beneficiary or beneficiaries designated in
              writing to Ceridian by Executive, (2) in the absence of such
              designation to the surviving spouse, or (3) if there is no
              surviving spouse, or such surviving spouse disclaims all or any
              part, then the full amount, or such disclaimed portion, shall be
              paid to the executor, administrator or other personal
              representative of Executive's estate.  The amount shall be paid as
              a lump sum as soon as practicable following Ceridian's receipt of
              notice of Executive's death.  All such payments shall be in
              addition to any payments due pursuant to Section 4.04(c) below.
 
       (b)    In the event of Executive's disability, Base Salary shall be
              terminated as of the end of the month in which the last day of the
              six-month period of Executive's inability to perform his or her
              duties occurs.
 
       (c)    In the event of termination by reason of Executive's death or
              disability, Ceridian shall pay to Executive any amount equal to
              (1) the amount Executive would have received in annual incentive
              plan bonus for the year in which termination occurs
 
 
                                       6
 
 
<PAGE>
 
 
              had "target" goals been achieved, multiplied by (2) a fraction,
              the numerator of which shall be the number of whole months
              Executive was employed in the year in which the death or
              disability occurred and the denominator of which is 12.  The
              amount payable pursuant to this Section 4.04(c) shall be paid
              within 15 days after the date such bonus would have been paid
              had Executive remained employed for the full fiscal year.
 
4.05   RETIREMENT.
 
       (a)    Executive may terminate this Agreement and Executive's employment
              as a result of Executive's decision to retire from Ceridian.
              Executive shall provide Ceridian with at least 75 days' written
              notice of the date upon which Executive intends to retire.
              Executive shall be paid at the usual rate of his or her annual
              Base Salary through the date of retirement stipulated in the
              written notice.
 
       (b)    In the event that Executive terminates this Agreement as a result
              of Executive's decision to retire from Ceridian and Executive is
              at least 55 years of age with five or more years of service to
              Ceridian, then Executive (and anyone entitled to claim under or
              through Executive) shall, until age 65, be entitled to receive
              from Ceridian the same or equivalent health, dental, accidental
              death and dismemberment, short and long-term disability, life
              insurance coverages, and all other insurance policies and health
              and welfare benefits programs, policies or arrangements, at the
              same levels and coverages as Executive was receiving on the day
              immediately prior to his or her retirement. Executive shall be
              required to pay no more for the above mentioned benefits than
              he/she paid as an active employee, or if provided by Ceridian
              at no cost to employees on the day immediately prior to
              Executive's retirement, they shall continue to be made
              available to Executive on this basis.
 
4.06   ENTIRE TERMINATION PAYMENT.  The compensation provided for in this
       Article IV for early termination of this Agreement and termination
       pursuant to this Article IV shall constitute Executive's sole remedy for
       such termination.  Executive shall not be entitled to any other
       termination or severance payment which may be payable to Executive under
       any other agreement between Executive and Ceridian.
 
 
                                     ARTICLE V

       (1) which does not relate (a) directly to the business of the employer or
       (b) to the employer's actual or demonstrably anticipated research or
       development, or (2) which does not result from any work performed by the
       employee for the employer.  Any provision which purports to apply to such
       an invention is to that extent against the public policy of this state
       and is to that extent void and unenforceable.
 
       Subdivision 2.
 
       No employer shall require a provision made void and unenforceable by
       subdivision 1 as a condition of employment or continuing employment.
 
       Subdivision 3.
 
       IF AN EMPLOYMENT AGREEMENT ENTERED INTO AFTER AUGUST 1, 1977, CONTAINS A

       DEVELOPED ENTIRELY ON THE EMPLOYEE'S OWN TIME, AND (1) WHICH DOES NOT
       RELATE (a) DIRECTLY TO THE BUSINESS OF THE EMPLOYER OR (b) TO THE

       OR (2) WHICH DOES NOT RESULT FROM ANY WORK PERFORMED BY THE EMPLOYEE FOR
       THE EMPLOYER.
 
5.06   EXECUTIVE'S DECLARATION. Executive has no inventions, data bases,
       improvements, discoveries, software, writings or other works of
       authorship useful to Ceridian in the normal course of business, which
       were conceived, made or written prior to the date of this Agreement and
       which are excluded from this Agreement.
 
5.07   SURVIVAL.  The obligations of this Article V shall survive the expiration
       or termination of this Agreement and Executive's employment.
 
 
                                     ARTICLE VI
 
              NON-COMPETITION, NON-RECRUITMENT, AND NON-DISPARAGEMENT
 
6.01   GENERAL.  The parties hereto recognize and agree that (a) Executive is
       a senior executive of Ceridian and is a key executive of Ceridian, (b)
       Executive has received, and will in the future receive, substantial
       amounts of Confidential Information, (c) Ceridian's business is
       conducted on a worldwide basis, and (d) provision for non-competition,
       non-recruitment and non-disparagement obligations by Executive is
       critical to Ceridian's continued economic well-being and protection of
       Ceridian's Confidential Information.  In light of these
       considerations, this Article VI sets forth the terms and conditions of
       Executive's obligations of non-competition, non-recruitment and
       non-disparagement subsequent to the termination of this Agreement
       and/or Executive's employment for any reason.
 
6.02   NON-COMPETITION.
 
       (a)    Unless the obligation is waived or limited by Ceridian in
              accordance with subsection (b) of this Section 6.02, Executive
              agrees that for a period of three years following termination of
              employment for any reason ("Non-Compete Period"), Executive will
              not directly or indirectly, alone or as a partner, officer,
              director, shareholder or employee of any other firm or entity,
              engage in any commercial activity in competition with any part of
              Ceridian's business as conducted as of the date of such
              termination of employment or with any part of Ceridian's
              contemplated business with respect to which Executive has
              Confidential Information.  For purposes of this subsection (a),
              "shareholder" shall
 
 
                                       9
 
<PAGE>
 
 
              not include beneficial ownership of less than five percent (5%)
              of the combined voting power of all issued and outstanding
              voting securities of a publicly held corporation whose stock is
              traded on a major stock exchange.  Also for purposes of this
              subsection (a), "Ceridian's business" shall include business
              conducted by Ceridian or its affiliates and any partnership or
              joint venture in which Ceridian or its affiliates is a partner
              or joint venturer; provided that, "affiliate" as used in this
              sentence shall not include any corporation in which Ceridian
              has ownership of less than fifteen percent (15%) of the voting
              stock.
 
       (b)    At its sole option Ceridian may, by written notice to Executive at
              any time within the Non-Compete Period, waive or limit the time
              and/or geographic area in which Executive cannot engage in
              competitive activity.
 
       (c)    During the Non-Compete Period, prior to accepting employment with
              or agreeing to provide consulting services to, any firm or entity
              which offers competitive products or services, Executive shall
              give 30 days prior written notice to Ceridian.  Such written
              notice shall describe the firm and the employment or consulting
              services to be rendered to the firm or entity, and shall include a
              copy of the written offer of employment or engagement of
              consulting services.  Ceridian's failure to respond or object to
              such notice shall not in any way constitute acquiescence or waiver
              of Ceridian's rights under this Article VI.
 
       (d)    In the event Executive has provided notice to Ceridian pursuant to
              subsection (c) of this Section 6.02 and has not accepted
              employment with or agreed to provide consulting services to, any
              firm or entity directly as a result of his or her non-competition
              obligation pursuant to this Section 6.02, Ceridian shall pay
              Executive an amount equal to the usual rate of Executive's Base
              Salary in effect at the time of termination on a regular payroll
              period basis until the end of the Non-Compete Period.  There shall
              be credited against Ceridian's obligation to make such payments
              any other payments made by Ceridian to Executive pursuant to
              Article IV of this Agreement.  In the event that Ceridian elects,
              pursuant to subsection (b) of this Section 6.02, to waive all or
              any portion of the non-competition obligation set forth in
              subsection (a) hereof, no payment shall be required by Ceridian
              with respect to the portion of the Non-Compete Period which has
              been waived.
 
       (e)    In the event Executive fails to provide notice to Ceridian
              pursuant to subsection (c) of this Section 6.02 and/or in anyway
              violates its non-competition obligation pursuant to Section 6.02,
              Ceridian may enforce all of its rights and remedies provided to it
              under this Agreement, in law and in equity, and Executive shall be
              deemed to have expressly waived any rights he or she may have had
              to payments under subsection (d) of this Section 6.02.
 
6.03   NON-RECRUITMENT.  For a period of three years following termination of
       employment for any reason, Executive will not initiate or actively
       participate in any other employer's recruitment or hiring of Ceridian
       employees.  This provision shall not preclude Executive
 
 
                                       10

       from responding to a request (other than by Executive's employer) for a
       reference with respect to an individual's employment qualifications.
 
6.04   NON-DISPARAGEMENT.  Executive will not, during the term or after the
       termination or expiration of this Agreement or Executive's employment,
       make disparaging statements, in any form, about Ceridian, its officers,
       directors, agents, employees, products or services which Executive knows,
       or has reason to believe, are false or misleading.
 
6.05   SURVIVAL.  The obligations of this Article VI shall survive the
       expiration or termination of this Agreement and Executive's employment.

                            determine constitutes a Change of Control.

       (including any transfer of property) in the nature of compensation, to or

                     (1)    A change in Executive's reporting responsibilities,
                            titles or offices as in effect immediately prior to
                            the Change of Control, or any removal of Executive
                            from, or any failure to re-elect Executive to, any
                            of such positions, which has the effect of
                            materially diminishing Executive's responsibility or
                            authority;
 
                     (2)    A reduction by Ceridian in Executive's Base Salary
                            as in effect immediately prior to the Change of
                            Control or as the same may be increased from time to
                            time thereafter;

                            location at the time of the Change of Control;

                            arrangements which, taken as a whole, provide
                            benefits to Executive at least reasonably comparable
                            to those discontinued or adversely affected, (A) the
                            failure by Ceridian to continue in effect, within
                            its maximum stated term, any pension, bonus,

                            or arrangement, in which Executive is participating
                            immediately prior to a Change of Control; or (B) the
                            taking of any action by Ceridian that would
                            materially adversely affect Executive's
                            participation or materially reduce Executive's
                            benefits under any of such plans, programs or
                            arrangements;
 
                     (5)    The failure by Ceridian to provide office space,
                            furniture, and secretarial support at least
                            comparable to that provided Executive immediately
                            prior to the Change of Control or the taking of any
                            similar action by Ceridian that would materially
                            adversely affect the working conditions in or under
                            which Executive performs his or her employment
                            duties;
 
 
                                      13
 
 
<PAGE>

                            Subsidiary, the sale, merger, contribution, transfer
                            or any other transaction in conjunction with which
                            Parent Corporation's ownership interest in such
                            Subsidiary decreases below the level specified in
                            Section 1.07 of Article I unless (A) this Agreement
                            is assigned to the purchaser/transferee with the
                            provisions of Article VII in full force and effect
                            and operative as if a Change of Control has occurred
                            with respect to the purchaser/transferee as Parent
                            Corporation immediately after the purchase/transfer
                            becomes effective, and (B) such purchaser/transferee
                            has a creditworthiness reasonably equivalent to
                            Parent Corporation's; or
 
                     (7)    Any material breach of this Agreement by Ceridian.
 
       (g)    "OTHER AGREEMENTS" means any agreement, contract or understanding
       heretofore or hereafter entered into between Executive and Ceridian for
       the direct or indirect provision of compensation to Executive.
 
7.02   CHANGE OF CONTROL TERMINATION RIGHT.  For a period of two years following
       a Change of Control that occurred during the term of this Agreement,
       Executive shall have the right, at any time and within Executive's sole
       discretion, to terminate employment with Ceridian for Good Reason.  Such
       termination shall be accomplished by, and effective upon, Executive
       giving written notice to Ceridian of Executive's decision to terminate.
       Except as otherwise expressly provided in this Agreement, upon the
       exercise of said right, all obligations and duties of Executive under
       this Agreement shall be of no further force and effect.
 
7.03   CHANGE OF CONTROL TERMINATION PAYMENT.
 
       (a)   In the event of a Change of Control Termination that occurred
             during the term of this Agreement, then, and without further
             action by the Board, Compensation Committee or otherwise, Ceridian
             shall, within five days of such termination, make a lump sum
             payment to Executive in an amount equal to three times the sum of
             (i) 12 months of Base Salary at the rate in effect at the time of
             Executive's termination, (ii) the bonus, if any, that Executive
             would have received under all applicable Ceridian bonus plans
             for the year in which the termination occurs had "superior" goals
             been achieved, and (iii) the annual perquisite cash adder
             Executive would have received in the year in which the termination
             occurs.
 
       (b)   In addition to the payments made pursuant to Section 7.03(a)
             hereof, in the event the Change of Control Termination that
             occurred during the term of this Agreement, then, and without
             further action by the Board, Compensation Committee or otherwise,
             Ceridian shall provide to Executive a pension supplement
             equivalent to the difference, if any, between: (i) the monthly
             benefits to which Executive would have been entitled under the
             defined benefit pension plan or plans in which Executive
             participates immediately prior to the Change of Control
             Termination which includes an additional five years of age and
             service for terminations on or prior to December 31, 2004 or an
             additional three years of age and service for terminations after
             December 31, 2004; and (ii) the amount to which Executive is, in
             fact, entitled under such defined benefit pension plan or plans.
 
       (c)   Neither the payments made or the pension supplement provided
             pursuant to this Section 7.03 nor any other compensation to be
             provided to Executive by Ceridian pursuant to this Agreement or
             any other agreement or Benefit Plan which may be considered Change
             of Control Compensation shall be subject to any limitation on
             Change of Control Compensation which may otherwise be expressed
             in any such agreement or Benefit Plan.

7.04   TAX REIMBURSEMENT.
 
       (a)    Anything in this Agreement to the contrary notwithstanding, in the
              event it shall be determined that any payments or distributions by
              Ceridian to or for the benefit of Executive (whether paid or
              payable or distributed or distributable pursuant to the terms of
              this Agreement or otherwise, but determined without regard to any
              payments required under this Section 7.04) (collectively, the
              "Payments") would be subject to the excise tax imposed by Section
              4999 of the Code or any interest or penalties are incurred by
              Executive with respect to such excise tax (such excise tax,
              together with any such interest and penalties, are hereinafter
              collectively referred to as the "Excise Tax"), then Executive
              shall be entitled to receive an additional payment (a "Gross-Up
              Payment") in an amount such that, after payment by Executive of
              all taxes (and any interest or penalties imposed with respect to
              such taxes), including any income taxes and Excise Tax imposed
              upon the Gross-Up Payment, Executive retains an amount of the
              Gross-Up Payment equal to the Excise Tax imposed upon the
              Payments.
 
       (b)    Subject to the provisions of Section 7.04(d), all determinations
              required to be made under this Section 7.04, including whether and
              when a Gross-Up Payment is required and the amount such Gross-Up
              Payment and the assumptions to be utilized in arriving at such
              determination, shall be made by Ceridian's external auditors (the
              "Accounting Firm"), which shall provide detailed supporting
              calculations both to Ceridian and Executive within 15 business
              days of the receipt of notice from Executive that there has been a
              Payment, or such earlier time as is requested by Ceridian.  In the
              event that the Accounting Firm is serving as accountant or auditor
              for the individual, entity or group effecting the Change of
              Control, Executive shall appoint another nationally recognized
              accounting firm to make the determinations required hereunder
              (which accounting firm shall then be referred to as the
              "Accounting Firm" hereunder).  All fees and expenses of the
              Accounting Firm shall be borne solely by Ceridian.  Any Gross-Up
              Payment, as determined pursuant to this Section 7.04, shall be
              paid by Ceridian to Executive within five days of the receipt of
              the Accounting Firm's determination.  Any determination by the
              Accounting Firm shall be binding upon Ceridian and Executive.
 
       (c)    As a result of uncertainty in the application of Section 4999 of
              the Code at the time of the initial determination by the
              Accounting Firm hereunder, it is possible that Gross-Up Payments
              which should have been made by Ceridian will not have been made
              ("Underpayment"), consistent with the calculations required to be
              made hereunder.  In the event that Ceridian exhausts its remedies
              pursuant to Section 7.04(d) and Executive thereafter is required
              to make a payment of any additional Excise Tax, the Accounting
              Firm shall determine the amount of the Underpayment that has
              occurred and any such Underpayment shall be promptly paid by
              Ceridian to or for the benefit of Executive.
 
 
                                      15
 
 
<PAGE>
 
 
 
       (d)    Executive shall notify Ceridian in writing of any claim by the
              Internal Revenue Service or any other taxing authority that, if
              successful, would require the payment by Ceridian of any Gross-Up
              Payment.  Such notification shall be given as soon as
              practicable but no later than ten business days after Executive
              knows of such claim and shall apprise Ceridian of the nature of
              such claim and the date on which such claim is requested to be
              paid.  Executive shall not pay such claim prior to the expiration
              of the thirty-day period following the date on which it gives
              such notice to Ceridian (or such shorter period ending on the
              date that any payment of taxes with respect to such claim is
              due).  If Ceridian notifies Executive in writing prior to the
              expiration of such period that it desires to contest such claim,
              Executive shall:
 
                            (i)    give Ceridian any information reasonably
                                   requested by Ceridian relating to such claim;
 
                            (ii)   take such action in connection with
                                   contesting such claim as Ceridian shall
                                   reasonably request in writing from time to
                                   time, including accepting legal
                                   representation with respect to such claim by
                                   an attorney reasonably selected by Ceridian;
 
                            (iii)  cooperate with Ceridian in good faith in
                                   order to effectively contest such claim; and
 
                            (iv)   permit Ceridian to participate in any
                                   proceedings relating to such claim;
 
              provided, however, that Ceridian shall bear and pay directly all
              costs and expenses (including additional interest and penalties)
              incurred in connection with such contest and shall indemnify and
              hold Executive harmless, on an after-tax basis, for any Excise Tax
              or income tax (including interest and penalties with respect
              thereto) imposed as a result of such representation and payment of
              costs and expenses.  Without limitation on the foregoing
              provisions of this Section 7.04(d), Ceridian shall control all
              proceedings taken in connection with such contest and, at its sole
              option, may pursue or forego any and all administrative appeals,
              proceedings, hearings and conferences with the taxing authority in
              respect of such claim and may, at its sole option, either direct
              Executive to pay the tax claimed and sue for a refund or contest
              the claim in any permissible manner, and Executive agrees to
              prosecute such contest to a determination before any
              administrative tribunal, in a court of initial jurisdiction and in
              one or more appellate courts, as Ceridian shall determine;
              provided further, however, that if Ceridian directs Executive to
              pay such claim and sue for a refund, Ceridian shall advance the
              amount of such payment to Executive on an interest-free basis and
              shall indemnify and hold Executive harmless, on an after-tax
              basis, from any
 
 
                                      16
 
 
<PAGE>
 
 
              Excise Tax or income tax (including interest or penalties with
              respect thereto) imposed with respect to such advance or with
              respect to any imputed income with respect to such advance; and
              provided further that any extension of the statute of
              limitations relating to payment of taxes for the taxable year
              of Executive with respect to which such contested amount is
              claimed to be due is limited solely to such contested amount.
              Furthermore, Ceridian's control of the contest shall be limited
              to issues with respect to which a Gross-Up Payment would be
              payable hereunder and Executive shall be entitled to settle or
              contest, as the case may be, any other issue raised by the
              Internal Revenue Service or any other taxing authority.
 
       (e)    If, after the receipt by Executive of an amount advanced by
              Ceridian pursuant to Section 7.04(d), Executive becomes entitled
              to receive any refund with respect to such claim, Executive shall
              (subject to Ceridian's complying with the requirements of Section
              7.04(d)) promptly pay to Ceridian the amount of such refund
              (together with any interest paid or credited thereon after taxes
              applicable thereto).  If, after the receipt by Executive of an
              amount advanced by Ceridian pursuant to Section 7.04(d), a
              determination is made that Executive shall not be entitled to any
              refund with respect to such claim and Ceridian does not notify
              Executive in writing of its intent to contest such denial of
              refund prior to the expiration of thirty days after such
              determination, then such advance shall be forgiven and shall not
              be required to be repaid and the amount of such advance shall
              offset, to the extent thereof, the amount of Gross-Up Payment
              required to be paid.
 
7.05   INTEREST.  In the event Ceridian does not make timely payment in full of
       the Change of Control Termination payment described in Section 7.03,
       Executive shall be entitled to receive interest on any unpaid amount at
       the lower of:  (a) the prime rate of interest (or such comparable index
       as may be adopted) established from time to time by the Bank of America
       National Trust and Savings Association, New York, New York or its
       successor in interest; or (b) the maximum rate permitted under Section
       280G(d)(4) of the Internal Revenue Code.
 
7.06   ATTORNEYS' FEES.  In the event Executive incurs any legal expense to
       enforce or defend his or her rights under this Article VII of this
       Agreement, or to recover damages for breach thereof, Executive shall be
       entitled to recover from Ceridian any expenses for attorneys' fees and
       disbursements incurred.
 
7.07   BENEFITS CONTINUATION.  In the event of a Change of Control Termination,
       Executive (and anyone entitled to claim under or through Executive)
       shall, until age 65, be entitled to receive from Ceridian the same or
       equivalent health, dental, accidental death and dismemberment, short and
       long-term disability, life insurance coverages, and all other insurance
       policies and health and welfare benefits programs, policies or
       arrangements, at the same levels and coverages as Executive was receiving
       on the day immediately prior to
 
 
                                      17
 
 
<PAGE>
 
 
       the Change of Control at a cost not to exceed the amount Executive would
       continue to pay had he/she continued to be an active employee of
       Ceridian.  To the extent that election of continuation of any of such
       coverages, programs, policies, or arrangements is made available to
       employees terminating at age 55 with 15 or more years of service,
       Executive shall be required to pay no more for continuation than is
       required of such employees on the day immediately prior to the Change
       of Control.  If no such continuation program is available, Executive
       shall be required to pay no more than he/she paid as an active employee,
       or if provided by Ceridian at no cost to employees on the day
       immediately prior to the Change of Control, they shall continue to be
       made available to Executive on this basis.
 
 
                                    ARTICLE VIII
 
                            CHANGE OF SUBSIDIARY STATUS
 
In the event that, prior to a Change of Control: (a) a Subsidiary is sold,
merged, contributed, or in any other manner transferred, or if for any reason
Parent Corporation's ownership interest in any such Subsidiary falls below the
level specified in Section 1.07, (b) Executive's primary employment duties are
with the Subsidiary at the time of the occurrence of such event, and (c)
Executive does not, in conjunction therewith, transfer employment directly to
Parent Corporation or another Subsidiary, then:
 
       (1)    If Executive gives his or her written consent to the assignment of
              this Agreement to such Subsidiary, or to the purchaser or new
              majority interest holder of such Subsidiary, (and such assignment
              is accepted) this Agreement shall remain in full force and effect
              between Executive and the assignee, except that the provisions of
              Article VII of this Agreement shall become null and void;
 
       (2)    If such assignment is not accepted by the Subsidiary or purchaser,
              then this Agreement shall be deemed to have been terminated by
              Ceridian without cause pursuant to Section 4.03 of Article IV; and
 
       (3)    In all other cases, this Agreement shall be deemed terminated for
              cause pursuant to Section 4.02 of Article IV.
 
 
                                     ARTICLE IX
 
                                 GENERAL PROVISIONS
 
9.01   NO ADEQUATE REMEDY.  The parties declare that it is impossible to measure
       in money the damages which will accrue to either party by reason of a
       failure to perform any of the obligations under this Agreement and
       therefore injunctive relief is appropriate.  Therefore, if either party
       shall institute any action or proceeding to enforce the provisions
 
 
                                      18
 
<PAGE>
 
 
       hereof, such party against whom such action or proceeding is brought
       hereby waives the claim or defense that such party has an adequate remedy
       at law, and such party shall not urge in any such action or proceeding
       the claim or defense that such party has an adequate remedy at law.
 
9.02   SUCCESSORS AND ASSIGNS.  Except as otherwise provided in Article VIII,
       this Agreement shall be binding upon and inure to the benefit of the
       successors and assigns of Parent Corporation and each Subsidiary, whether
       by way of merger, consolidation, operation of law, assignment, purchase
