3.1      If the Administrator receives valid Applications over an aggregate
         number of Shares which exceeds the amount stated pursuant to Rule 2.2
         or any limitation determined pursuant to Rule 5 below in respect of
         Invitations issued on any day, then the following steps shall be
         carried out successively to the extent necessary to eliminate the
         excess:

         (i)      each election for a Maximum Bonus to be included in the
                  repayment under the Savings Contract shall be deemed to be an
                  election for the Standard 5 Year Bonus to be included;



                                       11
<PAGE>

         (ii)     each election for a Standard 5 Year Bonus or a Standard 3 Year
                  Bonus to be included in the repayment under the Savings
                  Contract shall be deemed to be an election for the bonus to be
                  excluded;

         (iii)    the excess over L.5 of the monthly savings contribution
                  chosen by each applicant shall be reduced pro rata to the
                  extent necessary;

         (iv)     applications will be selected by lot, each based on a monthly
                  savings contribution of L.5 and the inclusion of no bonus in
                  the repayment under the Savings Contract.

3.2      If after applying the provisions of Rule 3.1(i) to (iii) inclusive the
         number of Shares available is still insufficient to enable an Option
         based on monthly savings contributions of Pound Sterling5 to be granted
         to each Eligible Employee who made a valid Application the Committee
         may, as an alternative to selecting by lot as in (iv) above, determine
         in its absolute discretion that no Options shall be granted.

3.3      If the Committee so determines the provision in Rule 3.1(i) to (iv)
         inclusive may be modified or applied in any manner as may be agreed in
         advance with the Inland Revenue.

3.4      Each Application shall be deemed to have been modified or withdrawn in
         accordance with the application of the foregoing provisions and the
         Administrator shall complete or procure the completion of each Savings
         Contract proposal form to reflect any reduction in monthly savings
         contributions resulting therefrom.


4.       GRANT OF OPTION

4.1      Within 30 days of the first day Invitations are issued (or of the date
         on which Eligible Employees are notified of the Exercise Price where
         such notification is made after Invitations are issued) or within 42
         days of that day when Rule 3 applies and Options cannot be granted
         within the 30 day period, the Grantor shall grant to each applicant who
         is still an Eligible Employee and is not precluded from participation
         in the Plan by virtue of Paragraph 8 of Schedule 9 an Option over the
         number of Shares for which, pursuant to Rule 2.4 and subject to Rule 3,
         he is deemed to have applied.



                                       12
<PAGE>

4.2      Where the circumstances noted in Rule 7.2 apply New Options may be
         granted within the terms of paragraph 15(1) of Schedule 9 in
         consideration for the release of Options previously granted under this
         Plan. Such New Options are deemed to be equivalent to the old Options
         and to have been granted within the terms of this Plan.

4.3      No Option may be transferred, assigned or charged and any purported
         transfer, assignment or charge shall be void ab initio. Each Option
         Certificate shall carry a statement to this effect. For the avoidance
         of doubt, this Rule 4.3 shall not prevent the Option of a deceased
         Option Holder being exercised by his personal representative(s) within
         the terms of these Rules.

4.4      As soon as possible after Options have been granted the Administrator
         shall issue an Option Certificate specifying the Date of Grant, the
         number of Shares subject to Option and the Exercise Price.

5.       LIMITATIONS ON GRANT

         Before Invitations are issued on any occasion, the Committee may
         determine a limit on the number of Shares which are to be available in
         respect of that issue of Invitations.

6.       EXERCISE OF OPTIONS

6.1      Subject to each of the succeeding sections of this Rule 6 and Rule 9
         any Subsisting Option may be exercised by the Option Holder or, if
         deceased, by his personal representatives in whole or in part at the
         time of or at any time following the occurrence of the earliest of the
         following events:

                  (i)     the Bonus Date;

                  (ii)    the death of the Option Holder;

                  (iii)   upon the Option Holder ceasing to be an employee of
                          the Group where that cessation was by reason of Injury
                          or Disability, Redundancy or Retirement;

                  (iv)    an opportunity to exercise the Option pursuant to
                          Rule 7;

                  (v)     upon the Option Holder ceasing to be a Group Employee,
                          where that cessation was by reason only that the
                          Company has ceased to have Control of such



                                       13
<PAGE>

                           company, or that the employment relates to a business
                           or part of a business which is transferred to a
                           person who is neither an associated company (within
                           the meaning of section 416 of the Act) of the Company
                           nor a company of which the Company has Control;

                  (vi)     the relevant Bonus Date, where the Option Holder
                           holds an employment in a company which is not a Group
                           Company but which is:

                           (a)      an Associated Company of the Company; or

                           (b)      a company of which the Company has control.

6.2      No Option may be exercised by an Option Holder at any time when he is,
         or by the personal representatives of an individual who at the date of
         his death was, precluded by paragraph 8 of Schedule 9 from
         participating in the Plan.

6.3      An Option shall lapse and become thereafter incapable of exercise on
         the earliest of the following events:

                  (i)      except where the Option Holder has died, the expiry
                           of six months following the Bonus Date;

                  (ii)     where the Option Holder died within six months
                           following the Bonus Date, the first anniversary of
                           the Bonus Date;

                  (iii)    where the Option Holder has died before the Bonus
                           Date, the first anniversary of his death;

                  (iv)     unless the Option Holder has died, on the expiry of
                           six months after the Option has become exercisable by
                           virtue of Rule 6.1(iii) and (v);

                  (v)      save in the circumstances in Rule 6.1 (ii), (iii),
                           (iv) and (v) above, and subject to Rule 6.5,
                           immediately following the Option Holder ceasing to be
                           a Group Employee;

                  (vi)     the expiry of six months after
                           the Option has first become exercisable in accordance
                           with Rule 7;



                                       14
<PAGE>

                  (vii)    the Option Holder being adjudicated bankrupt;

                  (viii)   upon the Option Holder giving notice, (or under the
                           terms of his Savings Contract being deemed to have
                           given notice), to the Nominated Savings Authority
                           that he intends to stop paying monthly contributions
                           under his Savings Contract prior to the date upon
                           which a right to exercise the Option shall arise; and

                  (ix)     on the winding up other than a voluntary winding up
                           of the Company.

6.4      If an Option Holder continues to be employed by a Group Company after
         the date on which he reaches the Specified Age he may exercise any
         Subsisting Option within six months following that date.

6.5      No person shall be treated for the purposes of this Rule 6 as ceasing
         to be a Group Employee until he is no longer a director or employee of
         the Company, any Associated Company or a company of which the Company
         has Control.

7.       TAKE-OVERS, RECONSTRUCTIONS AND LIQUIDATIONS

7.1      If any person obtains Control of the Company as a result of making:

         (i)      a general offer to acquire the whole of the issued share
                  capital of the Company (other than that which is already owned
                  by him) which is unconditional or which is made on a condition
                  such that if it is satisfied the person making the offer will
                  have Control of the Company; or

         (ii)     a general offer to acquire all the shares (other than shares
                  which are already owned by him) in the Company which are of
                  the same class as Shares subject to a Subsisting Option

         then the Committee shall notify all Option Holders as soon as is
         practicable of the offer in accordance with Rule 10.4. Any Subsisting
         Option may be exercised from the date of the receipt of that
         notification up to the expiry of a period ending six months from the
         time when the person making the offer has obtained Control of the
         Company and any condition subject to which the offer is made has been
         satisfied.



                                       15
<PAGE>

7.2      If as a result of the events specified in Rule 7.1 an Acquiring Company
         has obtained Control of the Company, the Option Holder may, if the
         Acquiring Company so agrees, release any Subsisting Option he holds in
         consideration for the grant of a New Option.

         A New Option issued in consideration of the release of an Option shall
         be evidenced by an Option Certificate which shall import the relevant
         provisions of these Rules.

         A New Option shall, for all other purposes of this Plan, be treated as
         having been acquired at the same time as the corresponding released
         Option and the definition of Date of Grant shall be construed
         accordingly.

7.3      If the Company passes a resolution for voluntary winding up, any
         Subsisting Option may be exercised within 6 months of the passing of
         the resolution.

7.4      The periods of exercisability under Rule 6.1(iv) and the date of lapse
         under Rule 6.3 (vi) are those of whichever of the pre-conditions of
         Rules 7.1 or 7.3 are first achieved. The subsequent achievement of any
         other pre-conditions will not cause a period of exercisability to begin
         nor a date of lapse to arise.

7.5      For the purpose of this Rule 7 other than Rule 7.2 a person shall be
         deemed to have obtained Control of a Company if he and others acting in
         concert with him have together obtained Control of it.

7.6      The exercise of an Option pursuant to the preceding provisions of this
         Rule 7 shall be subject to the provisions of Rule 9.

7.7      A New Option shall not be exercisable by virtue of the event pursuant
         to which it was granted.

8.       VARIATION OF SHARE CAPITAL

8.1      In the event of any variation of the share capital of the Company,
         including, but without prejudice to the generality of the preceding
         words, any capitalisation or rights issue or any consolidation,
         sub-division or reduction of capital by the Company, the number and
         nominal amount of Shares subject to any Option and the Exercise Price
         may be adjusted (including retrospective adjustments) by the Committee
         in such manner as is fair and reasonable provided that:



                                       16
<PAGE>

         (i)      the aggregate amount payable on the exercise of an Option in
                  full is neither materially changed nor increased beyond the
                  expected repayment under the Savings Contract at the Bonus
                  Date;

         (ii)     the Exercise Price for a Share subject to an Option to
                  Subscribe is not reduced below its nominal value unless (and
                  to the extent that) the Company is authorised to capitalise
                  from its undistributed profits or reserves upon the exercise
                  of such Option an amount equal to the difference between the
                  aggregate Exercise Price and the aggregate nominal value of
                  the Shares to be issued upon such exercise and to apply such
                  sum in paying up the difference;

         (iii)    at any time when the Plan remains approved by the Inland
                  Revenue no adjustment shall take effect without the prior
                  approval of the Board of Inland Revenue; and

         (iv)     at any time when the Plan remains approved by the Inland
                  Revenue following the adjustment the Shares continue to
                  satisfy the conditions specified in paragraphs 10 to 14
                  inclusive of Schedule 9.

                  Such variation shall be deemed to be effective, once Inland
                  Revenue approval has been given, from the record date at which
                  the respective variation applied to other shares of the same
                  class as the Shares. Any Options exercised within that period
                  shall be treated as exercised with the benefit of the
                  variation confirmed by the Auditors.

8.2      If an adjustment is made pursuant to Rule 8.1 above with the intention
         that the Plan shall cease to be approved by the Inland Revenue, the
         Company shall immediately notify the Inland Revenue.

8.3      The Administrator shall take such steps as he considers necessary to
         notify Option Holders of any adjustment made under Rule 8.1 and may
         call in, cancel, endorse, issue or reissue any Option Certificate
         consequent upon such adjustment.

9.       MANNER OF EXERCISE OF OPTIONS

9.1      No Option may be exercised whilst the Plan is and is intended to remain
         approved by the Inland Revenue unless the Shares satisfy the conditions
         specified in paragraphs 10 to 14 inclusive of Schedule 9.



                                       17
<PAGE>

9.2      An Option may only be exercised over the number of Shares which may be
         acquired with the sum obtained by way of payment under the related
         Savings Contract.

9.3      An Option shall be exercised by the Option Holder, or as the case may
         be by his personal representatives, delivering a notice in writing to
         the Treasurer of the Company, detailing the number of Shares in respect
         of which he wishes to exercise the Option accompanied by the
         appropriate payment (which shall not exceed the sum obtained by way of
         repayment under the related Savings Contract) or authority to the
         Company to withdraw and apply monies from the Savings Contract to
         acquire the Shares over which the Option is to be exercised and the
         relevant Option Certificate and shall be effective on the date of its
         receipt by the Treasurer of the Company.

9.4      The number of Shares specified in the notice of exercise given in
         accordance with Rule 9.3 shall be allotted and issued to the
         participant or at his discretion (if such participant shall have given
         notice that he wishes to sell some or all of the Shares so acquired)
         immediately following such acquisition within 30 days of the date of
         exercise and the Company shall arrange for the delivery of a definitive
         share certificate in respect thereof or, as the case may be, the
         appropriate changes to the books of the Company to reflect such
         allotment and issue of Shares. Save for any rights determined by
         reference to a record date preceding the date of allotment or transfer,
         such Shares shall rank pari passu with the other Shares of the same
         class in issue at the date of allotment or transfer.

9.5      When an Option is exercised only in part, it shall lapse to the extent
         of the unexercised balance.

9.6      For the purpose of Rules 9.2 and 9.3 above, any repayment under the
         Savings Contract shall exclude the repayment of any contribution the
         due date for payment of which falls after the date on which repayment
         is made unless provided for in the terms of the Savings Contract.

10.      ADMINISTRATION AND AMENDMENT

10.1     The Plan shall be administered by the Committee in conjunction with the
         Administrator and the Committee's decision on all disputes shall be
         final save where the Rules require the concurrence of the Auditors.

10.2     The Board may from time to time amend these Rules provided that:



                                       18
<PAGE>

         (i)      no amendment may materially affect an Option Holder as regards
                  an Option granted prior to the amendment being made unless 75%
                  of such Option Holders consent in writing to such amendment;

         (ii)     no amendment may be made which would make the terms on which
                  Options may be granted materially more generous or would
                  increase the limits specified in Rule 5 without the prior
                  approval of the Board;

         (iii)    no amendment may be made to the advantage of participants
                  without the prior approval of the Board (except for minor
                  amendments to benefit the administration of the Plan or to
                  take account of a change in legislation and amendments to
                  obtain or maintain favourable tax, exchange control or
                  regulatory treatment for participants in the Plan, the Company
                  or for Group Companies);

         (iv)     no amendment shall have effect until approved by the Board of
                  Inland Revenue whilst the Plan is and is intended to remain
                  approved by the Inland Revenue pursuant to Schedule 9; and

         (v)      no amendment made with the intention that the Plan shall cease
                  to be approved by the Inland Revenue shall take effect unless
                  at the same time the Inland Revenue is notified of such
                  amendment.

10.3     The cost of establishing and operating the Plan shall be borne by the
         Group Companies in such proportions as the Board shall determine.

10.4     Any notice or other communication under or in connection with the Plan
         may be given by the Company either personally or by post, and to the
         Company either personally or by post for the attention of : Corporate
         Treasury, Ceridian Corporation, 3311 East, Old Shakopee Road,
         Minneapolis, Minnesota 55425; items sent by airmail post shall be
         pre-paid and shall be deemed to have been received 7 days after posting
         and items sent by pre-paid Federal Express or similar shall be deemed
         to have been received 5 days after posting.

10.5     The Company shall at all times keep available sufficient authorised and
         unissued Shares to satisfy the exercise to the full extent of all
         Subsisting Options, taking account of any other obligations of the
         Company to issue unissued shares of the same class as Shares.



                                       19
<PAGE>

11.      COMPLIANCE WITH LAWS AND REGULATIONS

11.1     The exercise of any Subsisting Option and the issuance or transfer of
         Shares pursuant to Rule 9 shall be subject to compliance by the Company
         and by the Option Holder with all applicable requirements of law
         relating thereto and with all applicable regulations of any stock
         exchange on which the Shares of the Company may be listed at the time
         of such exercise by the Option Holder.

11.2     Prior to exercise of an Option, the Company may request the Option
         Holder to execute and deliver to the Company such representations in
         writing in order that the Company and the Option Holder comply with the
         applicable requirements of federal and state securities law.

12.      CESSATION OF EMPLOYMENT

         The rights and obligations of any individual under the terms of his
