                                    SERVICES

2.1      SERVICES TO BE PROVIDED. In addition to any obligation New Ceridian has
         to perform services for Ceridian pursuant to the Distribution Agreement
         and subject to the terms of this Agreement, New Ceridian will provide,
         or will cause a Subsidiary of New Ceridian to provide, to Ceridian or a
         Subsidiary of Ceridian the Services during the Term in a manner and at
         a level of service consistent in all material respects with the
         services provided to the Media Information Business as it existed prior
         to the Distribution Date.

2.2      STANDARD OF CARE. New Ceridian shall provide such Services exercising
         the same degree of care, priority and diligence as it exercises in
         performing the same or similar services for itself and its Affiliates
         (collectively, the "STANDARD OF CARE").

2.3      MODIFICATION OF SERVICES. Schedule A to this Agreement identifies the
         Services to be provided by New Ceridian and, subject to the mutual
         agreement of the parties hereto acting reasonably, it may be amended
         from time to time, to add any additional Services or to modify or
         delete Services. During the Term, service upgrades and improvements
         which New Ceridian provides to its own internal organizations will be
         made available to

                                      2

<PAGE>

         Ceridian to the extent that the parties mutually agree upon the price
         for any such upgrade or improvement.

2.4      INDEPENDENCE. Unless otherwise agreed in writing, all employees and
         representatives of New Ceridian will be deemed for purposes of all
         compensation and employee benefits matters to be employees or
         representatives of New Ceridian and not employees or representatives of
         Ceridian. In performing the Services, such employees and
         representatives will be under the direction, control and supervision of
         New Ceridian (and not Ceridian) and New Ceridian will have the sole
         right to exercise all authority with respect to the employment
         (including, without limitation, termination of employment), assignment
         and compensation of such employees and representatives.

2.5      NON-EXCLUSIVITY. Nothing in this Agreement shall preclude Ceridian from
         obtaining, in whole or in part, services of any nature that may be
         obtainable from New Ceridian, from its own employees or from providers
         other than New Ceridian.

2.6      COOPERATION. Ceridian shall, in a timely manner, take all such actions
         as may be reasonably necessary or desirable in order to enable or
         assist New Ceridian in the provision of the Services, including, but
         not limited to, providing necessary information and specific written
         authorizations and consents, and New Ceridian shall be relieved of its
         obligations hereunder to the extent that Ceridian's failure to take any
         such action renders performance by New Ceridian of such obligations
         unlawful or impracticable.

2.7      LIMITATION ON SERVICES. New Ceridian shall not be required to expand
         its facilities, incur new long-term capital expenses or employ
         additional personnel in order to provide the Services to Ceridian.
         Furthermore, New Ceridian shall not be obligated to provide Services
         hereunder that are greater in nature and scope than the comparable
         services provided by New Ceridian to Ceridian prior to the Distribution
         Date, or that are greater in nature or scope than comparable services
         provided by New Ceridian during the Term to its own internal
         organizations, except as may be specifically provided on Schedule A to
         this Agreement.

2.8      PERSONNEL. In providing the Services, New Ceridian as it deems
         necessary or appropriate in its sole discretion, may (a) use the
         personnel of New Ceridian or its Affiliates, and (b) employ the
         services of third parties to the extent such third party services are
         routinely utilized to provide similar services to other businesses of
         New Ceridian or are reasonably necessary for the efficient performance
         of any of such Services. Ceridian may retain at its own expense its own
         consultants and other professional advisers.

2.9      RIGHT TO DETERMINE PRIORITY. If there is an unavoidable conflict
         between the immediate needs of New Ceridian and those of Ceridian as to
         the use of or access to a particular Service to be provided by New
         Ceridian, New Ceridian shall have the right, in its sole discretion, to
         establish reasonable priorities, at particular times and under
         particular circumstances, as between New Ceridian and Ceridian. In any
         such situation, New Ceridian shall provide notice to Ceridian of the
         establishment of such priorities at the earliest practicable time.

                                   ARTICLE 3.

                              TERM AND TERMINATION

3.1      TERM. This Agreement shall become effective on the Distribution Date
         and shall remain in force for a period of one year (the "TERM"), unless
         terminated earlier pursuant to Section 3.2 below. Ceridian shall not
         have any obligation to continue to use any of the Services and may
         delete any Service from Schedule A that New Ceridian is providing to
         Ceridian by giving New Ceridian sixty (60) days notice thereof. In the
         event any Service is terminated by Ceridian, Schedule A shall be
         amended to reflect such amendment to the Services.

3.2      TERMINATION.

         (a)      TERMINATION WITHOUT CAUSE. The obligation of New Ceridian to
                  provide or cause to be provided each Service to be provided
                  hereunder shall terminate on the earliest to occur of:

                  (i)      The expiration of the Term;

                  (ii)     The expiration of the term (including any available
                           renewal term) during which such Service is to be
                           provided as specified in Schedule A, each such term
                           to commence on the Distribution Date;

                  (iii)    The date sixty (60) days following written notice
                           from New Ceridian that New Ceridian is discontinuing
                           permanently the provision of a Service to its own
                           internal organizations;

                  (iv)     The date sixty (60) days (or such longer period as is
                           specified in Schedule A) after New Ceridian receives
                           written notice that Ceridian no longer desires that a
                           Service be provided; or

                  (v)      The date of termination pursuant to Section 3.2(b).

         (b)      TERMINATION FOR CAUSE. Subject to Section 7.3, if either party
                  hereto shall fail to adequately perform in any material
                  respect any of its material obligations under this Agreement
                  (other than a payment default) (the "DEFAULTING PARTY"), the
                  other party entitled to the benefit of such performance (the
                  "NON-DEFAULTING PARTY") may give thirty (30) days' written
                  notice to the Defaulting Party specifying the nature of such
                  failure or default and stating that the Non-Defaulting Party
                  intends to terminate this Agreement, either in its entirety or
                  partially as set forth in Section 3.2(c), if such failure or
                  default is not cured within thirty (30) days of such written
                  notice. If any failure or default so specified is not cured
                  within such 30-day period, the Non-Defaulting Party may elect
                  to immediately terminate this Agreement in whole or in part
                  with respect to the Defaulting Party; provided, however, that
                  if the failure or default relates to a dispute contested in
                  good faith by the Defaulting Party, the Non-Defaulting Party
                  may not terminate this Agreement pending the resolution of
                  such dispute in accordance with Section 7.4 hereof. Such
                  termination shall be effective upon giving a written notice of
                  termination from the Non-Defaulting Party to the Defaulting
                  Party and shall be without prejudice to any other remedy which
                  may be available to the Non-Defaulting Party against the
                  Defaulting Party.

         (c)      PARTIAL TERMINATION. Under circumstances specified in Section
                  3.2(b) entitling the Non-Defaulting Party to terminate this
                  Agreement in its entirety, the Non-Defaulting Party shall have
                  the following options to partially terminate this Agreement
                  upon the same notice provisions as specified in Section
                  3.2(b):

                  (i)      If the default relates to the payment for a Service,
                           New Ceridian may terminate this Agreement as to the
                           provision of that Service or all Services to
                           Ceridian, but continue this Agreement in all other
                           respects; or

                  (ii)     If the default relates to the provision of a Service,
                           Ceridian may terminate this Agreement as to the
                           provision of that Service or all Services by New
                           Ceridian, but continue this Agreement in all other
                           respects.

3.3      EFFECT OF TERMINATION.

         (a)      Ceridian specifically agrees and acknowledges that all
                  obligations of New Ceridian to provide each Service for which
                  New Ceridian is responsible hereunder shall immediately cease
                  upon the termination of this Agreement. Upon the cessation of
                  New Ceridian's obligation to provide any Services, Ceridian
                  shall immediately cease using, directly or indirectly, such
                  Service (including, without limitation, any and all software
                  of New Ceridian or third party software provided through New
                  Ceridian, telecommunications services or equipment, or
                  computer systems or equipment).

         (b)      Upon termination of a Service with respect to which New
                  Ceridian holds books, records or files, including current or
                  archived copies of computer files, owned by Ceridian and used
                  by New Ceridian in connection with the provision of a Service
                  to Ceridian, New Ceridian will return all of such books,
                  records or files as soon as reasonably practicable; provided,
                  however, that New Ceridian may make a copy, at its expense, of
                  such books, records or files for archival purposes only.

         (c)      Without prejudice to the survival of the other agreements of
                  the parties, the following obligations shall survive the
                  termination of this Agreement: (a) the obligations of each
                  party under Section 3.3(b) and Articles 5 and 6, and (b) New
                  Ceridian's right to receive the Service Charges for the
                  Services provided by it hereunder pursuant to Section 4.1
                  below incurred prior to the effective date of termination.

                                   ARTICLE 4.

                                  COMPENSATION

4.1      SERVICE CHARGE. As consideration for the provision of the Services,
         Ceridian shall, for each Service performed, pay New Ceridian the
         applicable fee for such Service set forth in Schedule A to this
         Agreement, plus any additional charges as described below (such fee and
         any additional charges being collectively referred to in this Agreement
         as the "SERVICE CHARGE" for such Service. The fee for each Service
         provided by New Ceridian shall be either (a) a base fee, as specified
         in Schedule A, or (b) if not otherwise specified on Schedule A, New
         Ceridian's fully loaded cost for such Service. Unless otherwise stated
         in Schedule A, such allocations shall be made on a basis consistent
         with the allocation methodology used by New Ceridian immediately prior
         to the Distribution Date, which shall include a fair and reasonable
         allocation for New Ceridian's employee benefit costs relating to
         employees, and for New Ceridian's facilities and other overhead. In
         addition to the Service Charge for such Services, New Ceridian shall
         also be entitled to reimbursement from Ceridian upon receipt of
         reasonable supporting documentation for all out-of-pocket expenses
         incurred in connection with New Ceridian's provision of the Services
         which are not included as part of the normal allocated cost. In the
         event the Service is terminated, the Service Charge will be prorated
         for the number of days of Service received in the calendar month (based
         on a thirty day month) in which the Service is terminated.

4.2      INVOICING AND PAYMENTS.

         (a)      INVOICES. After the end of each month, New Ceridian, together
                  with its Affiliates and/or Subsidiaries providing Services
                  will submit one invoice to Ceridian for all Services provided
                  to Ceridian and Ceridian's Subsidiaries by New Ceridian during
                  such month. Such monthly invoices shall be issued when New
                  Ceridian issues its invoices in the ordinary course of its
                  business. Each invoice shall include a summary list of the
                  previously agreed upon Services for which there are fixed
                  dollar fees, together with documentation supporting each of
                  the invoiced amounts that are not covered by the fixed fee
                  agreements. The total amount set forth on such summary list
                  and such supporting detail shall equal the invoice total, and
                  will be provided under separate cover apart from the invoice.
                  All invoices shall be sent to the attention of Ceridian at the
                  address set forth in Section 7.8 hereof or to such other
                  address as Ceridian shall have specified by notice in writing
                  to New Ceridian.

         (b)      PAYMENT. Payment of all invoices in respect of Service shall
                  be made by check or electronic funds transmission in U.S.
                  Dollars, without any offset or deduction of any nature
                  whatsoever, within thirty (30) days of the invoice date.
                  Invoices unpaid as of such date shall accrue interest at an
                  annual rate of the lower of (i) two percentage points higher
                  than the reference rate publicly announced from time to time
                  by Bank of America, N.A. or (ii) the highest possible rate
                  allowed by applicable law. All payments shall be made to the
                  account designated by New Ceridian to Ceridian, with written
                  confirmation of payment sent by facsimile to New Ceridian or
                  other person designated thereby. If any payment is not paid
                  when due, New Ceridian shall have the right, without any
                  liability to Ceridian, or anyone claiming by or through
                  Ceridian, upon thirty (30) days' notice, to cease

                                       6

<PAGE>

                  providing any or all of the Services provided by New
                  Ceridian to Ceridian, which right may be exercised by New
                  Ceridian in its sole and absolute discretion.

4.3      TAXES. To the extent not included directly in the price New Ceridian

         PROVISION OF THE SERVICES FOR ANY INDIRECT, SPECIAL OR CONSEQUENTIAL

         DAMAGES.

         and its Affiliates, officers, directors, agents and employees

         liabilities, losses, damages, expenses, fines and penalties of any
         kind, including reasonable attorneys' fees and disbursements, incurred
         by the Indemnitees either:

         (a)      as the result of any claim made against the Indemnitees by any
                  third party arising out of New Ceridian's provision of the
                  Services (except to the extent, and only to the extent, of New

                  provided in Section 6.1 above); and/or

         have the right to audit New Ceridian's calculations and schedules
         thereto, of the costs and expenses for the Services provided hereunder.
         Upon the request of Ceridian, New Ceridian shall provide Ceridian with
         copies of invoices relating to any third party costs and expenses
         relating to the Services.

7.3      FORCE MAJEURE. Neither Ceridian nor New Ceridian shall be liable for

         limitation: acts of God, acts of government, fire, equipment breakdown,
         strikes or other similar labor disputes (settlements of which shall be
         in the sole discretion of the employer), or the inability to acquire
         materials or third-party services. Upon the occurrence of any event
         which is reasonably expected to or does cause a delay in the
         performance hereunder, the person or party hereto whose performance is
         or may be delayed shall give prompt written notice thereof to the other
         party to this Agreement. The parties hereto shall use reasonable

         follows. The appropriate Contact Persons for such dispute shall
         negotiate in good faith for a reasonable period of time to settle such
         dispute; provided, however, such reasonable period shall not, unless
         otherwise agreed by the parties in writing, exceed thirty (30) days
         from the time the parties began such negotiations. If after such
         reasonable period the Contact Persons are unable to settle the dispute,
         New Ceridian and Ceridian agree to settle such dispute in accordance
         with the dispute resolution mechanism set forth in Article VI of the
         Distribution Agreement.

         process, summons, notice or document by U.S. registered mail to such
         party's respective address set forth below shall be effective service
         or process for any action, suit or proceeding in Minnesota with respect
         to any matters to which it has submitted to jurisdiction in this
         Section 7.5. Each of the parties irrevocably and unconditionally waives
         any objection to the laying of venue of any action, suit or proceeding
         arising out of this Agreement or the transactions contemplated hereby
         in (i) the District Court, County of Hennepin, Fourth Judicial

         3.   USE. Subtenant shall use the Sublease Premises for general
office purposes and for no other purpose without Sublandlord's prior written
consent.

         4.   "AS IS" SUBLEASE; ALTERATIONS. Subtenant accepts the Sublease
Premises in "as is" condition, "with all faults". Subtenant will pay for the
installation and cost of any and all improvements, alterations or other work
required on or to the Sublease Premises or on or to any other portion of the
property and/or building of which the Sublease Premises are a part by the
Americans With Disabilities Act of 1990 or any other applicable law, rule or
regulation as a result of Subtenant's use of the Sublease Premises. Subtenant
shall make or install no other improvements, alterations or work on or to the
Sublease Premises or on, to or about the Building without the prior written
consent of Sublandlord (which consent shall not be unreasonably withheld) and
Prime Landlord (to the extent such consent is required under the Prime Lease).

         5.   RENT. Subtenant will pay monthly base rent for the Sublease
Premises in advance, without abatement, deduction or setoff, on the

during the Sublease Term, in an amount equal to $137,712.96 ("Base Rent").
Base Rent may increase on the anniversary of the Commencement

date as mutually agreed upon by the parties hereto. Subtenant will also pay,
as additional rent, Subtenant's Proportionate Share (as defined below) of all
other payments due the Prime Landlord under the Prime Lease, including,
without limitation, Additional Charges (as defined in the Prime Lease), as
and when they shall become due under the Prime Lease. For purposes of this
Sublease, "Subtenant's Proportionate Share" means the ratio of the Rentable
Area of the Sublease Premises to the Rentable Area of the Prime Lease
Premises expressed as a percentage.

         6.   PERFORMANCE OF PRIME LEASE BY SUBTENANT. Except as otherwise
set forth in this Sublease, Subtenant assumes and will keep, obey and perform
all of the terms, covenants and conditions of Sublandlord as Tenant under the
Prime Lease with respect to the Sublease Premises.

         7.   SUBTENANT'S RIGHTS AS TO PRIME LANDLORD. Sublandlord will not
be liable for any nonperformance of or noncompliance with or breach or
failure to observe any term, covenant or condition of the Prime Lease upon
Prime Landlord's part to be kept, observed, performed or complied with, or
for any delay or interruption in Prime Landlord's performing its obligations
thereunder. Sublandlord will, however, cooperate with and assist Subtenant in
enforcing the terms of the Prime Lease to the extent provided below.
Sublandlord assigns unto Subtenant, for so long as this Sublease shall be in
force and effect, any and all assignable rights and causes of action which
Sublandlord may have against Prime Landlord with respect to the Sublease
Premises due to defaults by Prime Landlord under the Prime Lease. Sublandlord
will cooperate with and join with Subtenant in any claims or suits brought by
Subtenant against Prime Landlord under the Prime Lease, provided that such
participation shall be without cost or expense to Sublandlord.

         8.   INSURANCE; WAIVERS. Subtenant will, during the Sublease Term,
continuously maintain commercial general liability insurance as required
under the Prime Lease, which insurance policy shall name Sublandlord as an
additional insured party, and a certificate thereof acceptable to Sublandlord
shall be delivered to Sublandlord prior to the delivery of the Sublease
Premises to Subtenant. Subtenant will indemnify and hold harmless Sublandlord
from, and will reimburse Sublandlord for, all costs and expenses, including
reasonable attorneys' fees, incurred by Sublandlord in connection with the
defense of all claims and demands of third persons, including but not limited
to those for death, personal injuries, or property damage, arising out of any
default of Subtenant in performing or observing any term, covenant, condition
or provision of this Sublease, or out of the use or occupancy of the Sublease
Premises by Subtenant, or out of any of the acts or omissions of the
Subtenant, its agents, representatives, employees, customers, guests,
invitees or other persons who are doing business with Subtenant or who are at
the Sublease Premises with Subtenant's consent. Subtenant, for itself and its
insurers, further expressly waives all claims against Sublandlord for any and
all damages to persons or property caused by or resulting from any thing or
circumstance.

         9.   ASSIGNMENT AND SUBLETTING. Subtenant may not, without the prior
written consent of Sublandlord (which may be withheld in Sublandlord's sole
discretion), assign or pledge this Sublease, sublet all or any part of the
Sublease Premises, allow any liens to be placed on this Sublease or the
Sublease Premises, or suffer this Sublease or the Sublease Premises or

                                       2
<PAGE>

any portion thereof to be attached or taken upon execution. Sublandlord may
assign its interest under this Sublease at any time, and in such case
Sublandlord shall be released from any liability arising under this Sublease
after the effective date of such assignment.

         10.  TERMINATION. This Sublease shall terminate at the end of the
Sublease Term hereof. Subtenant will peacefully and quietly vacate and
surrender the Sublease Premises to Sublandlord at the expiration of the
Sublease Term, in the condition called for under the Prime Lease. The
existence of this Sublease is dependent and conditioned upon the continued
existence of the Prime Lease, and in the event of the cancellation or
termination of the Prime Lease, this Sublease automatically shall be
terminated; provided, however, that this provision shall not be deemed to
release Sublandlord of liability if the Prime Lease is canceled or terminated
due to a default by Sublandlord as Tenant under the Prime Lease, which
default did not result, in whole or in part, from a default by Subtenant
under this Sublease. Sublandlord agrees not to amend, alter or modify any of
the provisions of the Prime Lease affecting Subtenant, or to surrender the
Prime Lease, without Subtenant's consent, which consent will not be
unreasonably withheld or delayed. Sublandlord shall have no liability to
Subtenant due to the termination of the Prime Lease by reason of any default
by Subtenant under this Lease, or by reason of any condemnation or
destruction of the Prime Lease Premises.

         11.  DEFAULT. If Subtenant defaults in its obligations under this
Sublease, Sublandlord shall have all of the same rights and remedies against
Subtenant as would be available to the Prime Landlord against Sublandlord if
Sublandlord were in default under the Prime Lease, as fully as if such rights
and remedies were set forth in this Sublease.

         12.  NOTICES. Any notice or demand permitted or required hereunder
shall be deemed given or made if, and shall not be deemed to have been given
or made unless, it is in writing and deposited in the United States mails
certified, return receipt requested, postage prepaid, or deposited with a
reputable overnight courier, addressed as follows:

         13.  ENTIRE AGREEMENT. This Sublease contains the entire agreement
between Sublandlord and Subtenant regarding the Sublease Premises. Subtenant
agrees that it has not relied on any statement, representation or warranty of
any person except as set out in this Sublease. This Sublease may be modified
only by an agreement in writing signed by Sublandlord and Subtenant. No
surrender of the Sublease Premises, or of the remainder of the Sublease Term,
will be valid unless accepted by Sublandlord in writing.

         14.  SUCCESSORS AND ASSIGNS. All provisions of this Sublease will be
binding on and for the benefit of the successors and assigns of Sublandlord
and Subtenant, except that no person or entity holding under or through
Subtenant in violation of any provision of this Sublease will have any right
or interest in this Sublease or the Sublease Premises.

         15.  SUBORDINATION; ATTORNMENT. The parties hereto acknowledge,
pursuant to the requirements of Section 7.13 of the Prime Lease, that this
Sublease is subject and subordinate to the Prime Lease and to all interests
to which the Prime Lease is or shall be subordinate, and that in the event of
termination, re-entry or dispossess by Prime Landlord under the Prime Lease,
Prime Landlord may, at its option, take over all of the right, title and
interest of Sublandlord hereunder, and Subtenant will, at Prime Landlord's
option, attorn to Prime Landlord pursuant to the then-executory provisions of
this Sublease, except that Prime Landlord will not: (A) be liable for any
previous act or omission of Sublandlord hereunder, (B) be subject to any
offset, not expressly provided herein, or (C) be bound by any previous
modification of this Sublease or by any previous prepayment of more than one
month's rent.

         16.  FACILITIES MANAGEMENT SERVICES. Throughout the Sublease Term,
Subtenant will provide on an "as requested" basis certain facilities
management services to Sublandlord pertaining to those portions of the Prime
Lease Premises actually occupied by Sublandlord (no such services shall be
provided to space which is sublet by Sublandlord to unrelated third parties).
Such services will include without limitation (A) tenant, community, Prime
Landlord and vendor relations, (B) environmental, health, ADA and safety
services including disaster planning, security, safety, first aid training
and inspections, (C) occupancy budgeting and costs analyses, (D)
telecommunications services including PBX-voice, voice mail and video

allocation/utilization management, and (I) new construction and/or renovation
services. Sublandlord will be billed periodically for all actual costs
incurred by Subtenant in providing such services, and Sublandlord will timely
pay for all such services as and when billed.
